    2010-12-01

    Full Text Available In this work, we provide two case studies on interoperability and transfer of knowledge in the environment of acompany dealing with plant protection. We find that the area of plant protection is highly oriented on workingwith knowledge. In this case interoperability of knowledge can play an important role in acquiring knowledgefrom different environments to solve specific problem in companies dealing with plant protection. Nevertheless,the concept of interoperability is well-developed on the level of data and information only.We stem from our previous works, where we defined a logical concept for the interoperability of knowledge onthe level of knowledge units. The objective of this work is to show how to apply our process model ofknowledge interoperability in a particular plant protection company. Two case studies are provided in order todemonstrate distinguishing between simple knowledge transfer and knowledge interoperability.

    While there has been interest in promoting the use of renewable energy in electricity production for a number of years in the United States, the market share of non-hydro renewable energy sources in electricity production has remained at about 2 percent over the past decade. The paper reviews the principal energy resources used for electricity production, considers the changing regulatory environment for the electricity industry, and describes government policies that have been used to promote green electricity in the United States, with an emphasis on measures adopted by state governments. Factors influencing the development of green power markets are also discussed, including underlying economic issues, public policy measures, the regulatory environment, external costs, and subsidies. Without significant increases in fossil fuel prices, much more stringent environmental regulations, or significant changes in electricity customer preferences, green electricity markets are likely to develop slowly in the United States.

    This report expands on a previous National Renewable Energy Laboratory (NREL) technical report (Lowder et al. 2015) that focused on the United States' unique approach to distributed generation photovoltaics (DGPV) support policies and business models. While the focus of that report was largely historical (i.e., detailing the policies and market developments that led to the growth of DGPV in the United States), this report looks forward, narrating recent changes to laws and regulations as well as the ongoing dialogues over how to incorporate distributed generation (DG) resources onto the electric grid. This report also broadens the scope of Lowder et al. (2015) to include additional countries and technologies. DGPV and storage are the principal technologies under consideration (owing to market readiness and deployment volumes), but the report also contemplates any generation resource that is (1) on the customer side of the meter, (2) used to, at least partly, offset a host's energy consumption, and/or (3) potentially available to provide grid support (e.g., through peak shaving and load shifting, ancillary services, and other means).

  10. Three case studies involving Leptospira interrogans serovar pomona infection in mixed farming units : case report

    Directory of Open Access Journals (Sweden)

    B. Gummow

    1999-07-01

    Full Text Available Three case studies involving Leptospira interrogans serovar pomona outbreaks within mixed farming systems in South Africa are described. On 2 farms, pigs constituted the main enterprise with cattle and sheep of secondary importance. On each of these 2 farms, abortion due to L. pomona in sows was confirmed by culture, and antibody titres to pomona were detected in cattle, sheep, horses and dogs. On the 3rd farm, a piggery was ofsecondary importance to cattle farming. Abortion and death in cows occurred on this farmand serology showed titres to various serovars, including pomona. L. pomona was also isolated from bovine urine, an aborted bovine foetus and kidneys from slaughtered pigs. This particular case study was regarded as clinically atypical in that adult Jersey cattle died of acute leptospirosis in a semiarid region of South Africa. In all 3 case studies, the poor management of pig effluent and of the drinking water and its sources played a pivotal role in the transmission of the disease. Inadequate vaccination of animals against Leptospira and poor record-keeping within the secondary farming enterprises were also contributing factors to the spread of leptospirosis.

    1981-01-01

    A case-control study of bladder cancer was conducted in five United States rubber and tyre companies to determine if there were high-risk jobs and work areas within the industry. The study included 220 male cases of bladder cancer, of whom 107 were identified from hospital record reviews and 113 from death certificates. Each case was matched individually with two industry controls by sex, race, year of birth, and company. One control was matched additionally by year of hire and duration of employment. Comparisons of cases and controls not matched by year of hire and age of hire showed no differences for those variables, which suggests that age and calendar period of first exposure to the industry were not risk determinants. When the work histories of both cases and controls were contrasted it was found that cases were more likely than controls to have worked in milling (odds ratio (OR) = 1.91) and calender operation (OR = 2.21) jobs. The relative risk estimates for milling and calender operation both exhibited linear trends of increase with duration of exposure. Milling and calender operation jobs entail potential exposures to volatilised reaction products from heated rubber stock. A better understanding of aetiological associations with job type will require more detailed characterisation of the work environment with regard to the sources and levels of aromatic amines and other suspected bladder carcinogens.

    The Par Pond unit designated under CERCLA consists of sediments within a Savannah River Site (SRS) cooling water reservoir. The sediments are contaminated with radionuclides and nonradioactive constituents from nuclear production reactor operations. The mercury in Par Pond is believed to have originated from the Savannah River. Because of Par Pond Dam safety Issues, the water level of the reservoir was drawn down, exposing more than 1300 acres of contaminated sediments and triggering the need for CERCLA interim remedial action. This paper presents the interim action approach taken with Par Pond as a case study. The approach considered the complexity of the Par Pond ecosystem, the large size of Par Pond, the volume of contaminated sediments, and the institutional controls existing at SRS. The Environmental Protection Agency (EPA) considers units with large volumes of low-concentration wastes, as is the case with Par Pond, to be {open_quotes}special sites.{close_quotes} Accordingly, EPA guidance establishes that the range of alternatives developed focus primarily on containment options and other remedial approaches that mitigate potential risks associated with the {open_quotes}special site.{close_quotes} The remedial alternatives, according to EPA, are not to be prohibitively expensive or difficult to implement. This case study also is representative of the types of issues that will need to be addressed within the Department of Energy (DOE) complex as nuclear facilities are transitioned to inactive status and corrective/remedial actions are warranted.

    Objective To evaluate Candida parapsilosis candidaemia in a neonatal unit over 7 years. Design Case series study. Setting A 2000-bed tertiary-care university hospital at São Paulo, Brazil. Participants Neonates hospitalised in a 63-bed neonatal unit. Primary and secondary outcome measures We evaluated the incidence of C parapsilosis fungemia in a neonatal unit from 2002 through 2008 and the main microbiological, clinical and epidemiological aspects of this disease in neonates. During the study period an outbreak occurred, an infection control programme was implemented, and isolates from blood and hand healthcare workers (HCWs) were submitted to molecular typing. Results During 7 years, there were 36 cases of C parapsilosis fungaemia and annual incidence varied from 0 to 19.7 per 1000 admissions. Evaluating 31 neonates with fungemia, the mean age at diagnosis was 19 days. All children except for one were premature; all had received total parenteral nutrition and all but one had used central venous catheter. Three neonates had received antifungal treatment previously to the diagnosis. Thirty-day mortality was 45%. Only lower birthweight was associated with mortality. C parapsilosis species complex was isolated from hand cultures in eight (11%) of the HCWs (one isolate was identified as C orthopsilosis). By molecular typing no HCW isolate was similar to any of the blood isolates. Conclusions The incidence of C parapsilosis fungemia in a neonatal unit varied widely over 7 years. We observed in our series a higher death rate than that reported in European countries and the USA. PMID:22869093

    2013-01-01

    The purpose of this case study was to examine environmental variables that lead to staff error in acute care settings: noise; lighting; ergonomics, furniture, and equipment; and patient room design and unit layout. Chaudhury, Mahmood, & Valente (2009) reviewed a number of design considerations related to reducing errors by nursing staff in acute care settings. The Neurological Rehabilitation Unit (NRU) at one hospital served to further examine the design recommendations outlined by Chaudhury et al. (2009). Based on photographs, a site tour, interviews with the NRU manager and with the son of a patient of 5 months, comparisons were made between the NRU and the acute care setting design considerations reviewed by Chaudhury et al. (2009). The NRU appeared to comply with many recommendations: enforced noise reduction was facilitated through limiting both the number of patients per room and the number of patients admitted to the unit. Distinct rooms were used for various tasks that helped to contain activity-based noise. A combination of daylighting and artificial lighting was in place, but efforts to control glare and thermal comfort were not integrated into the design. The ergonomic needs of employees were incorporated in the design of the NRU, and the layouts of patient rooms and the layout of the NRU in general also were compatible with the design recommendations reviewed by Chaudhury et al. (2009). Many of the design attributes advocated by Chaudhury et al. (2009) were included in the NRU. Supplemental research should be undertaken, however, to objectively measure nursing error, efficiency, and staff satisfaction with respect to the comparisons and assumptions presented in this study.

    Numerous epidemiologic investigations have identified links between high concentrations of arsenic in drinking water and cancer, although the risks at lower exposures are largely unknown. This paper presents the results of a case-control study of arsenic ingestion and bladder cancer in seven counties in the western United States. These counties contain the largest populations historically exposed to drinking water arsenic at concentrations near 100 microg/liter. All incident cases diagnosed from 1994 to 2000 were recruited. Individual data on water sources, water consumption patterns, smoking, and other factors were collected for 181 cases and 328 controls. Overall, no increased risks were identified for arsenic intakes greater than 80 microg/day (odds ratio=0.94, 95% confidence interval: 0.56, 1.57; linear trend, p=0.48). These risks are below predictions based on high dose studies from Taiwan. When the analysis was focused on exposures 40 or more years ago, an odds ratio of 3.67 (95% confidence interval: 1.43, 9.42; linear trend, p<0.01) was identified for intakes greater than 80 microg/day (median intake, 177 microg/day) in smokers. These data provide some evidence that smokers who ingest arsenic at concentrations near 200 microg/day may be at increased risk of bladder cancer.

    To assess the association between risk of sudden cardiac death and stressful law enforcement duties compared with routine/non-emergency duties. Case distribution study (case series with survey information on referent exposures). United States law enforcement. Summaries of deaths of over 4500 US police officers provided by the National Law Enforcement Officers Memorial Fund and the Officer Down Memorial Page from 1984 to 2010. Observed and expected sudden cardiac death counts and relative risks for sudden cardiac death events during specific strenuous duties versus routine/non-emergency activities. Independent estimates of the proportion of time that police officers spend across various law enforcement duties obtained from surveys of police chiefs and front line officers. Impact of varying exposure assessments, covariates, and missing cases in sensitivity and stability analyses. 441 sudden cardiac deaths were observed during the study period. Sudden cardiac death was associated with restraints/altercations (25%, n=108), physical training (20%, n=88), pursuits of suspects (12%, n=53), medical/rescue operations (8%, n=34), routine duties (23%, n=101), and other activities (11%, n=57). Compared with routine/non-emergency activities, the risk of sudden cardiac death was 34-69 times higher during restraints/altercations, 32-51 times higher during pursuits, 20-23 times higher during physical training, and 6-9 times higher during medical/rescue operations. Results were robust to all sensitivity and stability analyses. Stressful law enforcement duties are associated with a risk of sudden cardiac death that is markedly higher than the risk during routine/non-emergency duties. Restraints/altercations and pursuits are associated with the greatest risk. Our findings have public health implications and suggest that primary and secondary cardiovascular prevention efforts are needed among law enforcement officers. © Varvarigou et al 2014.

  20. Are Oligotypes Meaningful Ecological and Phylogenetic Units? A Case Study of Microcystis in Freshwater Lakes

    Oligotyping is a computational method used to increase the resolution of marker gene microbiome studies. Although oligotyping can distinguish highly similar sequence variants, the resulting units are not necessarily phylogenetically and ecologically informative due to limitations of the selected marker gene. In this perspective, we examine how oligotyping data is interpreted in recent literature, and we illustrate some of the method’s constraints with a case study of the harmful bloom-forming cyanobacterium Microcystis. We identified three Microcystis oligotypes from a western Lake Erie bacterial community 16S rRNA gene (V4 region) survey that had previously clustered into one OTU. We found the same three oligotypes and two additional sequence variants in 46 Microcystis cultures isolated from Michigan inland lakes spanning a trophic gradient. In Lake Erie, shifts in Microcystis oligotypes corresponded to spatial nutrient gradients and temporal transitions in bloom toxicity. In the cultures, Microcystis oligotypes showed preferential distributions for different trophic states, but genomic data revealed that the oligotypes identified in Lake Erie did not correspond to toxin gene presence. Thus, oligotypes could not be used for inferring toxic ecotypes. Most strikingly, Microcystis oligotypes were not monophyletic. Our study supports the utility of oligotyping for distinguishing sequence types along certain ecological features, while it stresses that 16S rRNA gene sequence types may not reflect ecologically or phylogenetically cohesive populations. Therefore, we recommend that studies employing oligotyping or related tools consider these caveats during data interpretation. PMID:28337183

    Full Text Available Background & Aims of the Study: Nowadays, heat stress is one of the most harmful physical agents in workplaces. According to the consequences of heat stress and have no information about it in Qom dry cleaner units, Iran, this study have been designed to evaluate the heat stress among workers of dry cleaner units in Qom province of Iran, in Jul-Aug 2011. Materials & Methods: This cross-sectional study was conducted in 113 units of active dry cleaner units. WBGT (Wet Bulb Globe Temperature index was selected for heat stress evaluation. In order to measure the requisite parameters, WBGT meter made of Casella Company had been used according to ISO 7243. Data had been analyzed according to Occupational Exposure Limits (OELs with SPSS V.16, using analysis of variance, independent T and LSD tests. Results: The average of WBGT index in Qom dry cleaner units of Iran were 28.98±1.64 °C. The average of WBGT index in 66.4% of units was up to 28°C. The average of relative humidity was 42.86%, the average of wet bulb temperature and globe temperature were 25.56°C and 36.72°C, respectively. The findings showed a significant correlation between the average of WBGT index and the standard recommendation level (p<0.0001. In dry cleaner units with less than 10 m2 area, heat stress was higher than other units  significantly (p<0.05. Conclusions: Heat stress in many dry cleaner units in Qom, Iran, was more than recommended OELs. Because of wet bulb and globe temperature in units were high value, the most important measures to heat controls, are technical engineering controls such as  radiation shield, insulation on boilers and modify the cooling systems.

    Full Text Available Forest management plans were firstly prepared and implemented in Turkey between 1963 and 1973. All forests in Turkey have been managed with timber oriented forest management philosophy; however, there have been some developments about inventory and silviculture techniques for approximately 40 years. Last decade, Turkey participated in Convention of Biological Diversity in Rio (1992 and included in both Pan – European and Near East Region Conventions. Nowadays, Turkish forest management philosophy has changed from timber management to ecosystem-based multiple-use forest planning with the principles of “sustainable forest management” criteria and indicators drafted in a few national and international agreements. Thus, Turkish forestry is underway in a restructuring process. This paper presents evolution of the traditional forest management philosophy in Turkey since 1963. This study was carried out in Artvin Planning Unit. Past two decade planning periods (managed under timber management approach was compared with current case study data used for forest multiple use management approach based on ecosystem in terms of distribution of age class, site class and change of volume and increment. In conclusion, former applications and techniques for adaptation of improvement must be analyzed and interpreted properly. Monetary resources and experts as well as legal, technique and scientific framework must be provided.

    This study was undertaken to improve the performance of a Chemotherapy Treatment Unit by increasing the throughput and reducing the average patient's waiting time. In order to achieve this objective, a scheduling template has been built. The scheduling template is a simple tool that can be used to schedule patients' arrival to the clinic. A simulation model of this system was built and several scenarios, that target match the arrival pattern of the patients and resources availability, were designed and evaluated. After performing detailed analysis, one scenario provide the best system's performance. A scheduling template has been developed based on this scenario. After implementing the new scheduling template, 22.5% more patients can be served. 1. CancerCare Manitoba is a provincially mandated cancer care agency. It is dedicated to provide quality care to those who have been diagnosed and are living with cancer. MacCharles Chemotherapy unit is specially built to provide chemotherapy treatment to the cancer patients of Winnipeg. In order to maintain an excellent service, it tries to ensure that patients get their treatment in a timely manner. It is challenging to maintain that goal because of the lack of a proper roster, the workload distribution and inefficient resource allotment. In order to maintain the satisfaction of the patients and the healthcare providers, by serving the maximum number of patients in a timely manner, it is necessary to develop an efficient scheduling template that matches the required demand with the availability of resources. This goal can be reached using simulation modelling. Simulation has proven to be an excellent modelling tool. It can be defined as building computer models that represent real world or hypothetical systems, and hence experimenting with these models to study system behaviour under different scenarios.1, 2 A study was undertaken at the Children's Hospital of Eastern Ontario to identify the issues behind the long waiting

Main Outcome Measures: Seropositivity for leptospirosis, patient demographics, risk factors, complications, treatment and survival. Results: One hundred and four patients were admitted with a clinical suspicion of leptospirosis. Fifty-three (50.7% were serologically confirmed cases. Males dominated both groups. Most of the admissions were in the monsoon season. Exposure to moist soil was the main risk factor. The mortality in the seronegative group was 26.8% while it was only 3.8% in the seropositive group. Multi-organ dysfunction syndrome, primarily acute respiratory distress syndrome with thromboctyopenia and renal failure were the causes for mortality. All the patients who died presented late into the illness. Conclusions: The initial diagnosis of leptospirosis depends on a high index of clinical suspicion, routinely available diagnostic tests being unreliable in the initial period. A reliable, unsophisticated test should be developed for early detection of this disease. As leptospirosis in its early stage mimics other tropical infections, both medical professionals and the general public (especially with risk of occupational exposure should be educated about the disease and the need to seek early medical intervention.

    Three case studies involving Leptospira interrogans serovar pomona outbreaks within mixed farming systems in South Africa are described. On 2 farms, pigs constituted the main enterprise with cattle and sheep of secondary importance. On each of these 2 farms, abortion due to L. pomona in sows was confirmed by culture, and antibody titres to pomona were detected in cattle, sheep, horses and dogs. On the 3rd farm, a piggery was of secondary importance to cattle farming. Abortion and death in cows occurred on this farm and serology showed titres to various serovars, including pomona. L. pomona was also isolated from bovine urine, an aborted bovine foetus and kidneys from slaughtered pigs. This particular case study was regarded as clinically atypical in that adult Jersey cattle died of acute leptospirosis in a semiarid region of South Africa. In all 3 case studies, the poor management of pig effluent and of the drinking water and its sources played a pivotal role in the transmission of the disease. Inadequate vaccination of animals against Leptospira and poor record-keeping within the secondary farming enterprises were also contributing factors to the spread of leptospirosis.

    Background Dabbing is an emerging method of marijuana ingestion. However, little is known about dabbing owing to limited surveillance data on dabbing. Objective The aim of the study was to analyze Google search data to assess the scope and breadth of information seeking on dabbing. Methods Google Trends data about dabbing and related topics (eg, electronic nicotine delivery system [ENDS], also known as e-cigarettes) in the United States between January 2004 and December 2015 were collected by using relevant search terms such as “dab rig.” The correlation between dabbing (including topics: dab and hash oil) and ENDS (including topics: vaping and e-cigarette) searches, the regional distribution of dabbing searches, and the impact of cannabis legalization policies on geographical location in 2015 were analyzed. Results Searches regarding dabbing increased in the United States over time, with 1,526,280 estimated searches during 2015. Searches for dab and vaping have very similar temporal patterns, where the Pearson correlation coefficient (PCC) is .992 (Poil and e-cigarette, in which the corresponding PCC is .931 (Pcannabis surveillance, and these findings can help enhance the understanding of the popularity of dabbing and provide insights for future research and informed policy making on dabbing.

    Precipitation frequently triggers shallow landslides in the Loess Plateau of Shaanxi, China, resulting in loss of life, damage to gas and oil routes, and destruction of transport infrastructure and farmland. To assess the possibility of shallow landslides at different precipitation levels, a method to draw slope units and steepest slope profiles based on ARCtools and a new method for calculating slope stability areproposed. The methods were implemented in a case study conducted in Yan’an, north-west China. High resolution DEM (Digital Elevation Model) images, soil parameters from in-situ laboratory measurements and maximum depths of precipitation infiltration were used as input parameters in the method. Next,DEM and reverse DEM were employed to map 2146 slope units in the study area, based on which the steepest profiles of the slope units were constructed. Combining analysis of the water content of loess, strength of the sliding surface, its response to precipitation and the infinite slope stability equation, a newequation to calculate infinite slope stability is proposed to assess shallow landslide stability. The slope unit stability was calculated using the equation at 10-, 20-, 50- and 100-year return periods of antecedent effective precipitation. The number of slope units experiencing failure increased in response to increasing effective antecedent rainfall. These results were validated based on the occurrence of landslides in recent decades. Finally, the applicability and limitations of the model are discussed.

    Darajat unit III geothermal power plant is developed by PT. Chevron Geothermal Indonesia (CGI). The plant capacity is 121 MW and load 110%. The greatest utilization power is consumed by Hot Well Pump (HWP) and Cooling Tower Fan (CTF). Reducing the utility power can be attempted by utilizing the wet bulb temperature fluctuation. In this study, a modelling process is developed by using Engineering Equation Solver (EES) software version 9.430.The possibility of energy saving is indicated by Specific Steam Consumption (SSC) net in relation to wet bulb temperature fluctuation from 9°C up to 20.5°C. Result shows that the existing daily operation reaches its optimum condition. The installation of Variable Frequency Drive (VFD) could be applied to optimize both utility power of HWP and CTF. The highest gain is obtained by VFD HWP installation as much as 0.80% when wet bulb temperature 18.5 °C.

    Full Text Available Anaerobic digestion technology is available for converting livestock waste to bio-energy, but its potential is far from fully exploited in the United States because the technology has a scale effect. Utilization of the centralized anaerobic digester (CAD concept could make the technology economically feasible for smaller dairy farms. An interdisciplinary methodology to determine the cost minimizing location, size, and number of CAD facilities in a rural dairy region with mostly small farms is described. This study employs land suitability analysis, operations research model and Geographical Information System (GIS tools to evaluate the environmental, social, and economic constraints in selecting appropriate sites for CADs in Windham County, Connecticut. Results indicate that overall costs are lower if the CADs are of larger size and are smaller in number.

    During the past decade, many community task forces have formed to address hoarding problems that come to public attention. Such task forces provide a societal-level intervention to assist people with the most severe cases of hoarding, who do not voluntarily seek or want help for their hoarding behaviour. This qualitative study of five U.S. hoarding task forces included sites selected for their diversity of purpose, approaches to hoarding intervention and community geography, composition and resources. Data were collected during the period of September 2007-March 2008. The case study methodology used multiple forms of data, including semi-structured interviews, analysis of documents, small group interviews and investigator observation. This study captured the perspectives of public and private sector service providers such as mental health, housing, social service, public health agencies and community enforcement organisations (fire, police, legal, animal control) to examine how task forces organise and operate and the emerging practice and policy changes. Study findings suggest that structural factors (e.g. leadership, purpose, funding and membership) impact hoarding task force viability, that participation on a task force influences practice and policy decisions about hoarding, and that social work can expand its role in task force leadership. Task forces may be a mechanism for improving community policies about hoarding and mechanisms for addressing other social problems across multiple sectors.

    Full Text Available Existing research on undocumented migration has focused predominantly on Latin American and Mexican immigrants and largely overlooked the experiences of immigrants originating from other parts of the world. As such, very few studies have considered how the lack of legal residency status can influence life opportunities of undocumented immigrants from Eastern Europe. The overarching aim of the present study was to explore the personal experiences of unauthorized Eastern European immigrants in the United States in order to: (a augment research on undocumented migration, and (b highlight the experiences of undocumented Eastern Europeans who remain an understudied group of the undocumented immigrants. Comprehensive personal interviews were conducted with a small group of unauthorized immigrants to explore: (1 reasons for immigration and prior expectations, and (2 psychosocial experiences (i.e., status related anxiety, experience with prejudice and discrimination, job satisfaction, sense of belonging, family relations, and future plans. Some of the results are presented in terms of similarity and differences between the current study's sample and the undocumented immigrants from other regions of the world, namely, Mexico and Latin America.

    The national forests (NFs) in the United States are protected areas managed for multiple purposes, and therefore are subject to both natural and anthropogenic disturbances. Monitoring forest changes arising from such disturbances and the post-disturbance recovery processes is essential for assessing the conditions of the NFs and the effectiveness of management approaches. In this study, we used time series stacks of Landsat images (LTSS) to evaluate the dynamics of seven NFs in eastern United States, including the De Soto NF, the Talladega NF, the Francis Marion NF, and the Uwharrie NF in southeastern U.S., and the Chequamegon NF, the Hiawatha NF, and the Superior NF in northern U.S. Each LTSS consisted of 12-14 Landsat images acquired for the same location, spanning from 1984 to 2006 with a nominal interval of one image every 2??years. Each LTSS was analyzed using a vegetation change tracker (VCT) algorithm to map forest disturbance. Accuracy assessments of the derived disturbance maps revealed that they had overall accuracy values of about 80%, with most of the disturbance classes having user's accuracies ranging from 70% to 95%. The producer's accuracies were generally lower, with the majority being in the range between 50% and 70%. While this may suggest that the disturbance maps could slightly underestimate disturbances, a more detailed assessment of the omission errors revealed that the majority of the disagreements were due to minor disturbances like thinning or storm damages that were identified by the image analysts but were not captured by the VCT algorithm. The derived disturbance year maps revealed that while each of the seven NFs consisted of 90% or more forest land, significant portions of the forests were disturbed since 1984. Mapped disturbances accounted for about 30%-45% of total land area in the four NFs in southeastern U.S. and about 10%-20% in the three NFs in northern U.S. The disturbance rates were generally higher in the buffer zones

    Food misdescription has become of paramount importance as consumers come into contact daily with a great variety of foods. The controversies surrounding genetically modified organism (GMO) labelling and malpractices in the food chain have forced regulatory authorities to authenticate food from production to consumption. This paper reports the results of a surveillance programme conducted in the United Arab Emirates (UAE) market to assess the status of food misdescription and authenticity. A DNA test was used to screen random samples of processed meat products bought from supermarkets in the UAE. A total of 246 samples were analysed from different geographical locations. The majority of samples showed a high standard of legal compliance, with over 95% confirmed for authenticity. However, 5% of samples were found to contain undeclared species. In conclusion, this study confirms the presence of undeclared food in the UAE market. Regular surveillance and monitoring programmes along with strict implementation of the Food and Adulteration Act may alleviate misdescription issues to a greater extent.

    Taking its development in Baoding City as an example, we introduced service fields of rural cooperative economic organized united association. It mainly includes setting up service platform and providing scientific and technological services; organizing economic and trade negotiation and exchange, and promoting farmer-supermarket partnership; providing financial services and solving fund-raising problems. In line with these fields, we analyzed existing problems: (i) regional development is unbalanced and organization lacks internal connection; (ii) the development in some counties (cities) is to be improved, and the promotion effect is not significant; (iii) there is shortage of talent and the innovation strength is not enough; and (iv) it lacks system and management lacks restriction mechanism. Finally, we put forward countermeasures and recommendations: strengthen propaganda and cultivate farmers’ cooperative awareness; incorporate rural cooperative economic organized united association into formal system arrangement, and absorb professional talents; innovate upon organization system of rural cooperative economic organized united association and improve service methods; improve internal operating mechanism and innovate upon working contents of rural cooperative economic organized united association at new development background.

    Full Text Available This article addresses the difficulties faced by farmers who implement new production methods on their land. We discuss the nature of the new competences that farmers must develop, highlighting the complexities of the means they use, the difficulties they confront in this process, and the strategies farmers develop in consonance with the practical knowledge of their profession. The method used includes elements of Ergonomic Work Analysis combined with a case study. Le Boterf's model of the process of constructing competences is used to support the data analysis. The discussion is organized based on an analysis of the evolution of consolidated competences that are re-elaborated for a new agricultural production. The analysis of the strategies and operational modes is introduced, and their contribution to the development of new competences is noted, thus enriching the model proposed by Le Boterf. It is essential to understand the cognitive processes, strategies, and operating modes involved in the development of competences. This procedure provides mechanisms that preserve the opportunity for observation of significant variables in managing variability to be included in the transformation or evolution of work situations and to define the activities that workers will perform.

    This is a review of the United States experience with issues of child health and services as they relate to changes in economic trends. No existing data systems are entirely adequate for reporting on the current health status of children. An important consideration for the monitoring of children's health in the United States is the status of subgroups such as those who are disadvantaged for reasons of poverty, discrimination or geographic isolation. Ample evidence confirms that children living in poverty suffer adverse health consequences and that the proportion of children living in poverty in the United States has increased steadily since 1975 and dramatically since 1981. Most measures of health status and health risks for children show steady improvements throughout the 1970s. The exercise of public responsibility for financing and providing essential services and supports held constant or improved during this period, especially during the recession of 1974-75. The health status and risks for children since 1981 appear to be adversely affected which must be attributed to a combination of circumstances that include serious recession, increased poverty rates for households with children and diminished health benefits and social support services. These findings suggest that when either local or widespread economic reversals are anticipated, health services and social supports for children need to be expanded rather than contracted.

  13. Groundwater Drought and Recovery: a Case Study from the United Kingdom

    Peach, D.; McKenzie, A. A.; Bloomfield, J.

    2012-12-01

    An understanding of the processes leading to the onset, duration and end of hydrological droughts is necessary to help improve the management of stressed or scarce water resources during such periods. In particular, the role and use of groundwater during episodes of drought is crucially important, since groundwater can provide relatively resilient water supplies during early stages of drought but maybe highly susceptible to relatively persistent or sustained droughts. Nevertheless, groundwater is seldom considered in drought analyses, and compared with other types of hydrological drought there have been few studies to date. The few previous studies of groundwater droughts at catchment- and regional-scale have shown that catchment and aquifer characteristics exert a strong influence on the spatio-temporal development of groundwater droughts as water deficit propagates through the terrestrial water cycle. In this context, the relationships between hydrogeological heterogeneity, catchment engineering infrastructure (storage), and decisions related to water resource management during drought events all shape the evolution and consequences of groundwater droughts. Here we examine the evolution of a recent regionally significant two-year drought across the United Kingdom (UK) and use it to investigate these relationships. We identify the drivers, characterise the development and spatio-temporal extent of the groundwater drought. In particular, we focus on the unusually rapid end and recovery from drought during what would normally be a period of groundwater recession. The UK, and in particular southern England, relies extensively on groundwater for public water supply, agricultural and industrial use, as well as for sustaining river flows that are essential to ecosystem health. In normal years relatively consistent rainfall patterns prevail, recharging aquifers over winter when evapotranspiration is minimal. However, by March 2012 large parts of the southern UK had

    There are a number of theoretical frameworks which aim to provide a language for understanding and discussing the nature of power and influence in organisational decision making. One of the most recent and comprehensive frameworks is that developed by Mintzberg. Following a resumé of the most pertinent sections of Mintzberg's framework, this paper uses it to investigate the power relationships in an NHS Mental Health Unit (MHU) considering NHS Trust status. This investigation reveals some important conclusions about the nature of power in the NHS but also explores some of the limitations of the framework as a descriptive and predictive tool.

    Coal fires occur in all coal producing nations. Like most other environmental problems fires are not confined by political boundaries. Important economic coal seams in the United States are found across the Inter-montaine west, the Midwest, and Appalachia. The age of these deposits differs, as does the grade and sulfur content of the coal, the mining techniques utilized for exploitation of this resource, and the markets in which the coal is traded. Coal fires are ordinary occurrences under extraordinary conditions. Every coal bed exposed in an underground or surface mine has the potential to ignite. These fires are spread thinly over the political geography and over time, so that constituencies rarely coalesce to petition government to address the coal fire problem. Coal fires produce serious problems with long term consequences for society. They threaten mine safety, consume a non-renewable resource, and produce toxic gases with serious health effects for local populations. Additionally, as coal production in the developing world intensifies, these problems worsen. The lack of government attention to coal fires is due to the confluence of at least four independent political factors: 1) The separated powers, federated system in which decisions in the United States are made; 2) Low levels of political energy available in Congress to be expended on coal fires, measured by the magnitude of legislative majorities and seniority; 3) The mid-twentieth century model of scientific and technical information moving indirectly to legislators through the bureaucratic agencies; 4) The chronic and diffuse nature of fires across space and time.

    Psychological interventions in cardiac rehabilitation programs appear relevant in as much they significantly contribute to achieve the goals of rehabilitation, to reduce the risk of relapses and to improve patients' adherence to therapy. To this aim, motivational interviewing (MI) has shown promising results in improving motivation to change and individuals' confidence in their ability to do so. The purpose of this article is to integrate theory with practice by describing a three-session case scenario. It illustrates how MI's skills and strategies can be used to enhance heart-healthy habits. MI may be synergistic with other treatment approaches and it is used here in conjunction with brief strategic therapy. By the use of MI principles and techniques, the patient reported an increase in his motivation and ability to change, developing a post discharge plan that incorporates self-care behaviors. MI may be effective in motivating and facilitating health behavior change among obese patients suffering from heart failure.

    Full Text Available This article describes the novel phenomenon of librarian-initiated publications discovery (LIPD in state-level digital depositories in the United States. LIPD is a series of actions taken by digital depository librarians to discover and inspect government Web sites and select Web content qualifying as government publications for inclusion in the state depositories. In a current popular model in which states employ OCLC Digital Archive™ for the depositories, the power of content selection has shifted from government agencies (content producers to digital depositories. This study systematically documented and compared the LIPD actions in four case states and developed a LIPD process model for descriptive and analytic purposes. It also discusses the impacts and challenges facing the changing practices in preserving government information as historical record. [Article content in Chinese

    Recent research from the United Kingdom (UK) has highlighted some of the differences in breast cancer presentations between women of different ethnic groups. Analysis of a large database showed that Black women of African or Caribbean heritage living in England and Wales are more likely to present with stage 3 or 4 cancer than White British women and less likely to have their cancer detected through screening. In many countries around the world, migrant and cultural minority groups experience social and economic disadvantage and this is reflected in their health outcomes. With world migration at record levels, it is timely to reflect on ethnic disparities and to consider how developed nations can care for their minority groups, which are increasing in number and diversity. These issues and challenges are discussed, using the UK's migrant population and Australia's Indigenous and migrant populations as case studies.

  7. Assessing potential human health hazards and benefits from subtherapeutic antibiotics in the United States: tetracyclines as a case study.

    Science.gov (United States)

    Cox, Louis Anthony Tony; Popken, Douglas A

    2010-03-01

    Many scientists, activists, regulators, and politicians have expressed urgent concern that using antibiotics in food animals selects for resistant strains of bacteria that harm human health and bring nearer a "postantibiotic era" of multidrug resistant "super-bugs." Proposed political solutions, such as the Preservation of Antibiotics for Medical Treatment Act (PAMTA), would ban entire classes of subtherapeutic antibiotics (STAs) now used for disease prevention and growth promotion in food animals. The proposed bans are not driven by formal quantitative risk assessment (QRA), but by a perceived need for immediate action to prevent potential catastrophe. Similar fears led to STA phase-outs in Europe a decade ago. However, QRA and empirical data indicate that continued use of STAs in the United States has not harmed human health, and bans in Europe have not helped human health. The fears motivating PAMTA contrast with QRA estimates of vanishingly small risks. As a case study, examining specific tetracycline uses and resistance patterns suggests that there is no significant human health hazard from continued use of tetracycline in food animals. Simple hypothetical calculations suggest an unobservably small risk (between 0 and 1.75E-11 excess lifetime risk of a tetracycline-resistant infection), based on the long history of tetracycline use in the United States without resistance-related treatment failures. QRAs for other STA uses in food animals also find that human health risks are vanishingly small. Whether such QRA calculations will guide risk management policy for animal antibiotics in the United States remains to be seen.

    Full Text Available This thesis observed the recent trend of privatization and the effect of foreign investment, and the example of the overseas experience of sale of the state-own enterprises. To study the enlightenment of the strategy which attracted foreign investment by way of privatization or the issue the Korean government needs to be paid attention to when foreigners invest in public sections. The most important enlightenment getting from the foreign instances is that although it takes a long time before privatization, the foreign investment could be effectively attracted and the price could be risen maximum only when the stable and transparent restriction system is established. In order to get a price as high as possible, the sell of stocks should be done in many times. Promote the competition of demand between investment institutions and private investors. Control and make use of the financial institutions properly by way of various attractive economic policies. And so on.

    This paper examines the feasibility of using multivariate data analysis (MVDA) for supporting some of the key activities that are required for successful manufacturing of biopharmaceutical products. These activities include scale-up, process comparability, process characterization, and fault diagnosis. Multivariate data analysis and modeling were performed using representative data from small-scale (2 L) and large-scale (2000 L) batches of a cell-culture process. Several input parameters (pCO2, pO2, glucose, pH, lactate, ammonium ions) and output parameters (purity, viable cell density, viability, osmolality) were evaluated in this analysis. Score plots, loadings plots, and VIP plots were utilized for assessing scale-up and comparability of the cell-culture process. Batch control charts were found to be useful for fault diagnosis during routine manufacturing. Finally, observations made from reviewing VIP plots were found to be in agreement with conclusions from process characterization studies demonstrating the effectiveness of MVDA as a tool for extracting process knowledge.

    Making material available through learning management systems is standard practice in most universities, but this is generally seen as an adjunct to the 'real' teaching, that takes place in face-to-face classes. Lecture attendance is poor, and it is becoming increasingly difficult to engage students, both in the material being taught and campus life. This paper describes the redevelopment of a large course in scientific practice and communication that is compulsory for all science students studying at our Melbourne and Malaysian campuses, or by distance education. Working with an educational designer, a blended learning methodology was developed, converting the environment provided by the learning management system into a teaching space, rather than a filing system. To ensure focus, topics are clustered into themes with a 'question of the week', a pre-class stimulus and follow up activities. The content of the course did not change, but by restructuring the delivery using educationally relevant design techniques, the content was contextualised resulting in an integrated learning experience. Students are more engaged intellectually, and lecture attendance has improved. The approach we describe here is a simple and effective approach to bringing this university's teaching and learning into the 21 (st) century.

  12. Expectations and reality: a case study of return migration from the United States to Southern Italy.

    Science.gov (United States)

    Cerase, F P

    1974-01-01

    A summary of Italy's emigration flows shows that Southern Italy sent her people abroad in great number, and, at the same time, return migration to Italy has been characteristic of a minority, e.g., an estimated 3000 from the US alone, 1964-68. Italy's modernization proceeded unevenly, the South remaining agricultural and for the most part, economically backward. Any form of identification with Italy as a country did not affect the Southern peasant thus preparing his/her way to emigrate as soon as any opportunity presented itself. Due to all the conditions which facilitated emigration from Italy on an individualistic and nonideological basis and without an understanding of the economic forces pushing the emigrant out, and in view of the lack of understanding of how the New World economy of the US was constituted, it is no surprise that the return migration of some remained as much ad hoc and based solely on individual motivations as was the emigration. The 2 fundamental approaches to the concept of immigrant both start by considering the immigrant in his/her new situation. 1 approach views the immigrant's success in the new situation as dependent upon acquiring values and patterns of behavior which would resolve his/her problems in the new society. According to the other approach, in order to resolve the problems of his/her new situation the immigrant must become critically aware of the consequences of his/her actions. The 1st view of conceiving integration has been prevalent, particularly in the study of international migration. And, mass migration from Italy, from the emigrant's perspective, is connected to a repeatedly unsuccessful search for economic success and failure to reach prevailing cultural objectives. The act of emigration, of abandonment, may thus be seen as the resolution of the disparity between the means at the emigrant's disposal and the objectives he/she seeks. The great majority succeed but some fail, and if they have a home and family to return

    1998-07-01

    This report analyses the driving forces of, and barriers to, biomass energy technology implementation with the objective of defining the most important factors behind the growth of bioenergy markets and suggesting strategies for policy makers and investors. The approach is to describe the important factors for the development of real bioenergy markets at two levels: (1) Institutional, primarily policy, and (2) market structure. Concepts from economic theory, primarily transaction cost theory and industrial organisation, are used in a qualitative way. The report is based on literature studies and field studies of bioenergy markets in three countries: the United States of America, Austria, and Sweden. It is divided into five sections. After the introduction in section one, literature with relevance for this study is reviewed in section two. In section three the energy policy and energy sectors of each country are described. The descriptions include an overview of the biomass energy sectors. Five cases of developed bioenergy markets in the three countries are presented in section four. The cases are residential heating with wood pellets in New Hampshire, United States, biomass power production in Maine, residential heating with pellets in Sweden, biomass district heating in Sweden, and biomass district heating in Austria. All markets are described in terms of the historical development, technical issues, economics, market structure and local policy influences. In the discussion in section five a number of key factors behind the success or failure of bioenergy are presented. Six factors are most important: (1) Complementaries between the bioenergy operations and another activity (for instance when the bioenergy production uses biomass waste products from another industry); (2) economics of scale within the bioenergy business through larger production series, standards, specialization etc.; (3) a competitive bioenergy market (Many sellers and buyers operate in the

    Full Text Available Background: Prevention of accidents—a crucial requirement in oil industries—involves hazard recognition, risk assessment, and corrective actions. The purpose of this study was to compare the ETBA and HAZOP techniques for risk assessment in a gasoline refinery unit. Methods: In this case study, data were collected using process flow diagram, walking–talking through method, piping and instrumentation diagram, and direct observations. Worksheets for both techniques were filled on the basis of the risk assessment matrix MIL-STD-882E. Results: The HAZOP method identified 44 deviations attributable to 118 causes. In addition, 11.37% of the identified hazards were associated with unacceptable risk, and 36.36%, with unfavorable risk. The ETBA method detected 10 groups of energy (24 subgroups; 33 hazards were detected, 10.62% of which were associated with unacceptable risk. Conclusion: HAZOP proved to be the more powerful technique for the prediction and identification of hazards. However, ETBA detected certain hazards that were not identifiable using HAZOP. Therefore, a combination of these two methods is desirable for the assessment of hazard risk in process industries.

    A qualitative study was conducted that reflected an analysis of a 6-week poetry unit in a language arts classroom of 6th and 8th graders at a school for the deaf in a large city in the northeastern United States. The school served a large population of children of poverty who were of Latino and African American descent. The study was guided by 4 research questions: (a) Would students benefit from having American Sign Language (ASL) poetry as a part of the unit? (b) Would teachers' signing of poems increase students' understanding of the poems? (c) Could students analyze the meaning of poems independently? (d) Would students view writing poetry as a vehicle for expressing their feelings and ideas through themes that were important to them? The evidence provided support for affirmative answers to questions a, b, and d.

    2014-05-01

    Full Text Available In this article we explore recent history to uncover the role that public engagement has played in the effort to reform America's urban schools. In the place of narratives that focus on elite actors (foundations, unions, corporations, etc., we focus on the role of local stakeholders. Specifically, we look to how the changing political context (policy agendas and governance structures of urban school systems has shifted possibilities for communities to participate in determining the direction of reform efforts in urban school systems. Through interviews and archival research, we examine the case of a single parent-led advocacy organization, Parents United for the D.C. Public Schools. Established in 1980 and remaining active until the late 1990s, Parents United developed a broad-based vision of educational equity and had a significant impact on the local public school system during that time.  We show that in the current political and social context of education reform, communities may derive important lessons from Parents United while also devising new strategies for public engagement.

  20. Detecting Robust Patterns in the Spread of Epidemics: A Case Study of Influenza in the United States and France

    CERN Document Server

    Crépey, Pascal

    2008-01-01

    In this paper, the authors develop a method of detecting correlations between epidemic patterns in different regions that are due to human movement and introduce a null model in which the travel-induced correlations are cancelled. They apply this method to the well-documented cases of seasonal influenza outbreaks in the United States and France. In the United States (using data for 1972-2002), the authors observed strong short-range correlations between several states and their immediate neighbors, as well as robust long-range spreading patterns resulting from large domestic air-traffic flows. The stability of these results over time allowed the authors to draw conclusions about the possible impact of travel restrictions on epidemic spread. The authors also applied this method to the case of France (1984-2004) and found that on the regional scale, there was no transportation mode that clearly dominated disease spread. The simplicity and robustness of this method suggest that it could be a useful tool for dete...

    2008-06-01

    The Aguadulce aquifer unit in southeastern Spain is a complex hydrogeological system because of the varied lithology of the aquifer strata and the variability of the processes that can take place within the unit. Factorial analysis of the data allowed the number of variables to be reduced to 3 factors, which were found to be related to such physico-chemical processes as marine intrusion and leaching of saline deposits. Variographic analysis was applied to these factors, culminating in a study of spatial distribution using ordinary kriging. Mapping of the factors allowed rapid differentiation of some of the processes that affect the waters of the Gador carbonate aquifer within the Aguadulce unit, without the need to recur to purely hydrogeochemical techniques. The results indicate the existence of several factors related to salinity: marine intrusion, paleowaters, and/or leaching of marls and evaporitic deposits. The techniques employed are effective, and the results conform to those obtained using hydrogeochemical methods (vertical records of conductivity and temperature, ion ratios, and others). The findings of this study confirm that the application of such analytical methods can provide a useful assessment of factors affecting groundwater composition.

    The Algerian desert dominates large parts of the country's vast territory, and Algeria is among the countries filling most of the world's largest desert. In fact the country is over 80% desert. Even though more than 80% of the population is located in the northern Mediterranean coastal zone, most of oil and gas fields are located in the country's vast southern desert called Sahara. Furthermore, the desert region is developed into a major tourist destination. This arid zone region is characterized by a lack of potable water. However, in addition to the abundant solar energy, the region is also endowed with important wind and brackish groundwater resources with different qualities. Therefore, a brackish water greenhouse desalination unit that is powered by wind energy is a good solution for desalting groundwater for irrigation purposes in this region. Brackish water can be used to cool the greenhouse, creating the proper climate to grow valuable crops. Moreover, at the same time the fresh water that is produced in this system may be sufficient for the irrigation of crops grown inside the unit. In this study, five typical regions in the Sahara were selected and investigated. These regions were selected since they were areas of traditional agriculture. The frequency distributions of wind speed data were collected from Surface Meteorology and Solar Energy (SSE) statistics developed by NASA and evaluated for a 10-year period. The distributions were used to determine the average wind speed and the available wind power for the five locations. The results indicated that the available wind energy is a suitable resource for power production and can be used to provide the required electricity for the brackish groundwater greenhouse desalination units.

    Infill drilling of wells on a uniform spacing, without regard to reservoir performance and characterization, must become a process of the past. Such efforts do not optimize reservoir development as they fail to account for the complex nature of reservoir heterogeneities present in many low permeability carbonate reservoirs. New and emerging technologies such as cross-borehole tomography, geostatistical modeling, and rigorous decline type curve analysis can be used to quantify reservoir quality and the degree of interwell communication. These results can be used to develop a 3-D simulation model for prediction of infill locations. In this work, the authors will demonstrate the application of reservoir surveillance techniques to identify additional reservoir ``pay`` zones, and to monitor pressure and preferential fluid movement in the reservoir. These techniques are: long-term production and injection data analysis, pressure transient analysis, and advanced open and cased hole well log analysis. The major contribution of this paper is the summary of cost effective reservoir characterization and management tools that will be helpful to both independent and major operators for the optimal development of heterogeneous, low permeability carbonate reservoirs such as the North Robertson (Clearfork) Unit.

    Novel policy interventions may lack evaluation-based evidence. Considerations to introduce minimum unit pricing (MUP) of alcohol in the UK were informed by econometric modelling (the 'Sheffield model'). We aim to investigate policy stakeholders' views of the utility of modelling studies for public health policy. In-depth qualitative interviews with 36 individuals involved in MUP policy debates (purposively sampled to include civil servants, politicians, academics, advocates and industry-related actors) were conducted and thematically analysed. Interviewees felt familiar with modelling studies and often displayed detailed understandings of the Sheffield model. Despite this, many were uneasy about the extent to which the Sheffield model could be relied on for informing policymaking and preferred traditional evaluations. A tension was identified between this preference for post hoc evaluations and a desire for evidence derived from local data, with modelling seen to offer high external validity. MUP critics expressed concern that the Sheffield model did not adequately capture the 'real life' world of the alcohol market, which was conceptualized as a complex and, to some extent, inherently unpredictable system. Communication of modelling results was considered intrinsically difficult but presenting an appropriate picture of the uncertainties inherent in modelling was viewed as desirable. There was general enthusiasm for increased use of econometric modelling to inform future policymaking but an appreciation that such evidence should only form one input into the process. Modelling studies are valued by policymakers as they provide contextually relevant evidence for novel policies, but tensions exist with views of traditional evaluation-based evidence. © The Author 2013.

    Full Text Available Abstract Background Non alcoholic fatty liver disease (NAFL consists in the accumulation of fat vacuoles in the cytoplasm of hepatocytes. Many etiologic factors are associated with NAFL, such as, the metabolic syndrome factors, medications, bariatric surgery, nutritional disorders. However, very little information is available on the clinical relevance of this disorder as a health problem in the general population. Methods and design The aim of the study is establish the risk factors most frequently associated with NAFL in a general adult population assigned to the primary care units and to investigate the relationship between each component of the metabolic syndrome and the risk of having a NAFL. A population based case-control, observational and multicenter study will be carried out in 18 primary care units from the "Area de Gestión del Barcelonés Nord y Maresme" (Barcelona attending a population of 360,000 inhabitants and will include 326 cases and 370 controls. Cases are defined as all subjects fulfilling the inclusion criteria and with evidence of fatty liver in an abdominal ultrasonography performed for any reason. One control will be randomly selected for each case from the population, matched for age, gender and primary care center. Controls with fatty liver or other liver diseases will be excluded. All cases and controls will be asked about previous hepatic diseases, consumption of alcohol, smoking and drugs, and a physical examination, biochemical analyses including liver function tests, the different components of the metabolic syndrome and the HAIR score will also be performed. Paired controls will also undergo an abdominal ultrasonography. Discussion This study will attempt to determine the factors most frequently associated with the presence of NAFL investigate the relationship between the metabolic syndrome and the risk of fatty liver and study the influence of the different primary care professionals in avoiding the evolution

    Mass media influence public acceptability, and hence feasibility, of public health interventions. This study investigates newsprint constructions of the alcohol problem and minimum unit pricing (MUP). Quantitative content analysis of 901 articles about MUP published in 10 UK and Scottish newspapers between 2005 and 2012. MUP was a high-profile issue, particularly in Scottish publications. Reporting increased steadily between 2008 and 2012, matching the growing status of the debate. The alcohol problem was widely acknowledged, often associated with youths, and portrayed as driven by cheap alcohol, supermarkets and drinking culture. Over-consumption was presented as a threat to health and social order. Appraisals of MUP were neutral, with supportiveness increasing slightly over time. Arguments focused on health impacts more frequently than more emotive perspectives or business interests. Health charities and the NHS were cited slightly more frequently than alcohol industry representatives. Emphases on efficacy, evidence and experts are positive signs for evidence-based policymaking. The high profile of MUP, along with growing support within articles, could reflect growing appetite for action on the alcohol problem. Representations of the problem as structurally driven might engender support for legislative solutions, although cultural explanations remain common. © The Author 2014.

    Research by the USDA-Agricultural Research Service (ARS) on biological control of weeds has been practiced for many years because of its inherent ecological and economic advantages. Today, it is further driven by ARS adherence to Presidential Executive Order 13112 (3 February 1999) on invasive species and to USDA-ARS policy toward developing technology in support of sustainable agriculture with reduced dependence on non-renewable petrochemical resources. This paper reports examples or case studies selected to demonstrate the traditional or classical approach for biological control programs using Old World arthropods against Tamarix spp, Melaleuca quinquenervia (Cav) ST Blake and Galium spurium L/G aparine L, and the augmentative approach with a native plant pathogen against Pueraria lobata Ohwi = P montana. The examples illustrated various conflicts of interest with endangered species and ecological complexities of arthropods with associated microbes such as nematodes.

    Geomechanical investigations in shale reservoir are crucial to understand rock behavior during hydraulic fracturing treatment and to solve borehole wall stability problem. Anisotropy should be considered as key mechanical parameter while trying to characterize shale properties in variety of scales. We are developing a concept of step-by-step approach to characterize and upscale the Consistent Lithological Units (CLU) at several scales of analysis. We decided that the most regional scale model, comparable to lithostratigraphic formations, is too general for hydraulic fracture propagation study thus a more detailed description is needed. The CLU's hierarchic model aims in upscale elastic properties with their anisotropy based on available data from vertical borehole. For the purpose of our study we have an access to continuous borehole core profile and full set of geophysical logging from several wells in the Pomeranian part of the Ordovician and Silurian shale complex belongs to the Baltic Basin. We are focused on shale properties that might be crucial for mechanical response to hydraulic fracturing: mineral components, porosity, density, elastic parameters and natural fracture pattern. To prepare the precise CLU model we compare several methods of determination and upscaling every single parameter used for consistent units secretion. Mineralogical data taken from ULTRA log, GEM log, X-ray diffraction and X-ray fluorescence were compared with Young modulus from sonic logs and Triaxial Compressive Strength Tests. The results showed the impact of clay content and porosity increase on Young's modulus reduction while carbonates (both calcite and dolomite) have stronger impact on elastic modulus growth, more than quartz, represented here mostly by detrital particles. Comparing the shales of similar composition in a few wells of different depths we concluded that differences in diagenesis and compaction due to variation in formation depth in a range of 1 km has negligible

    Full Text Available The present study aims to analyze, on the one hand, the flash-floods forming potential in the Subcarpathian sector of Buzău catchment, an area with high susceptibility to hydrological hazards such as flash-floods, and, on the other hand, the vulnerability of the territorial-administrative units to these risk phenomena. Thus, in the first stage, the Flash floods Susceptibility Index (FFSI index was defined for the Subcarpathian sector of Buzău catchment, based on environmental factors with a relatively static nature, considered causal factors in the flash-flood phenomena genesis. The next stage of this work was the delimitation of the vulnerability index of the territorial-administrative units, based on the highest FFSI index values which correspond to the built surfaces from the analyzed units. The results showed that more than 80% of the territorial-administrative units are exposed to flood phenomena, while almst 20% is currently under serious risk of damage in case of hydrological risk phenomena occurrence.

    Full Text Available Many Romanian cities are confronted with difficulties regarding the insertion of redundant industrial objectives in the present urban landscape. This study focuses on two industrial units that have created a certain place identity through time, both undergoing a conversion process, due to relict or underused industrial structures. These industrial units are reclaimed by the increasingly public demand for new construction spaces that are more adapted to the cultural, social, economic and ecological context. Belvedere Cigarette Factory was an important factory in Bucharest because it initiated the tobacco manufacturing in the Romanian capital city. The buildings of the cigarette factory, which were constructed from the late 19th century until the early 20th century, are considered heritage objectives. Currently, some factory buildings and annexes are demolished and in their place shopping and entertainment spaces have been built. S.C. MEFIN S.A. Sinaia was established on a pre-existing industrial unit in 1953 and in 2007 it was decided to be integrated into the services sector (tourist accommodation, commercial spaces, sports and leisure in order to raise the attractiveness of the area. However, the transformation of this unit cannot be dissociated from the community`s preferences regarding the area`s revitalization (Stan A, 2009, p. 201. The methods applied in this study are the case study research and the survey that allows the comparison of the reuse perception of the industrial units. The need to return these productive areas to the urban context recognizes people (residents as active participants in the revitalization process of industrial landscapes.

    Afshin Afshari

    2014-01-01

    Full Text Available A consensus is forming among experts that the best way to achieve emissions’ reduction in the near and mid-term is increasing the demand-side energy efficiency—this is especially true in developing countries where the potential for demand reduction is significant and achievable at relatively lower cost. Enhanced energy efficiency also reduces energy costs and can result in a financial benefit to end-users, if the life-cycle value of energy savings offsets the upfront cost of implementing the measure. At the same time, reducing energy demand translates into lower pull for fossil fuel import and supply/distribution capacity expansion. An ideal candidate for the implementation of demand-side energy efficiency measures is the building sector, since it contributes to a large extent to the total amount of greenhouse gases (GHGs emitted worldwide. In most developing countries, the contribution of the building sector to the total national GHG emissions is significantly higher than the worldwide average. This is in part due to the lower level of industrial activity. Other drivers of the high emissions of the building sector are the inefficiency of the envelope and technical systems of the existing buildings, as well as harsh climatic conditions requiring the use of energy intensive air-conditioning equipment. The United Arab Emirates (UAE currently have the highest ecological footprint per capita in the world. The Emirate of Abu Dhabi, the focus of this study, can be expected to have a footprint that is even higher, being the largest economy and the major oil producer among the seven Emirates. In addition to the environmental consequences of unrestrained energy consumption, the fact that energy prices are heavily subsidized in Abu Dhabi results in a significant financial burden for the government. In the UAE and the Emirate of Abu Dhabi, the air-conditioning load in buildings is the ideal target for demand-side management because it constitutes more

    Full Text Available This paper presents results of the study of feed quality and its effect on the performance of the fluid catalytic cracking unit using Port-Harcourt Refinery Company (PHRC as a case study. The important feed qualities used are the hydrocarbon content and a hydrotreated feed. Data on the feed properties used in PHRC were collected and a product mass balance was carried out on the fluid catalytic cracking unit. Conversion and gasoline yield of the unit were found to be 73.43 vol% and 52.07 vol% respectively. On comparison with cracking of aromatic feed, from literature, with 61.3 vol% conversion and 45.64 vol% gasoline yields, the feed is said to be paraffinic because of its higher conversion and gasoline yield. On comparison with that collected for hydrotreated feed, 80.62 vol% conversion and 63.9 vol% gasoline yield, it is concluded that feed hydrotreating increases conversion and gasoline yield by a significant amount.

    The aim of this paper was to outline a proposed a new brackish water greenhouse desalination unit powered by geothermal energy for the development of arid and relatively cold regions, using Algeria as a case study. Countries which have abundant sea/brackish water resources and good geothermal conditions are ideal candidates for producing fresh water from sea/brackish water. The establishment of human habitats in these arid areas strongly depends on availability of fresh water. The main advantage of using geothermal energy to power brackish water greenhouse desalination units is that this renewable energy source can provide power 24 h a day. This resource is generally invariant with less intermittence problems compared to other renewable resources such as solar or wind energy. Geothermal resources can both be used to heat the greenhouses and to provide fresh water needed for irrigation of the crops cultivated inside the greenhouses. A review of the geothermal potential in the case study country is also outlined. (author)

    The United State federal program coordinates scientific research on Global Change that provides useful information for the public and national and international policymakers? The U.S. Global Change Research Program (USGCRP) was started in 1990 by an act of Congress and it has sought the advice of the U.S. academies of science, engineering, and medicine. The academies have a special relationship to the government which draws upon the expertise of the academies to provide rigorous peer reviewed advice. Specifically, the academies' advisory committee and its other committees helps identify future directions and priorities, provides consensus on science controversies, gives a "state of science', and technical analyses, peer review documents, serves as neutral convening body, and facilitates collaboration. The academies produce reports, workshops, and reports. One of the major tasks of the USGCRP is to produce a National Climate Assessment (NCA) report about every four years, which is reviewed by the academies and the public. This report provides "mature" and balanced scientific information to a broad set of sectors and regional stakeholders as well as local, regional and national governments that are involved in decision-making. Recently the USGCRP representatives have held a meeting with United Kingdom assessment representatives to compare and learn from each other about different national assessment methods.

As a manager or a supervisor, it is your job to make sure that the desperate pieces of a mosaic fit together in a harmonious, coordinated way, maximally utilizing the talents and abilities of each employee. If skillfully managed, this diversity can bring a competitive advantage to an organization. If not, however, the bottom line can be negatively affected, and the work environment can become unwelcoming. Dealing with a diverse work group is new terrain for most managers and supervisors.

    Full Text Available This manuscript uses data from the U.S. Environmental Protection Agency to analyze the potential for energy recovery from wastewater treatment plants via anaerobic digestion with biogas utilization and biosolids incineration with electricity generation. These energy recovery strategies could help offset the electricity consumption of the wastewater sector and represent possible areas for sustainable energy policy implementation. We estimate that anaerobic digestion could save 628 to 4,940 million kWh annually in the United States. In Texas, anaerobic digestion could save 40.2 to 460 million kWh annually and biosolids incineration could save 51.9 to 1,030 million kWh annually.

    2008-01-01

    The main purpose of this paper is to describe and analyze the ways of inserting physicians into the health production process. This subject is justified by a belief that that this way of working may be a problem but at the same time may well be the key to implementing healthcare models that are ethically and politically committed to the lives of public health system users. Initially, the problem is presented through the construction of an archetype physician and his historical and social and cultural conditioning factors, taking the work processes of physicians at Basic Healthcare Units in Belo Horizonte as an example that is built up through interviews and participative observations. Some possibilities for intervention are indicated through the introduction of new concepts and technologies that could transform the work of these practitioners in ways that would build up links with more responsibility for the care and lives of users of public healthcare services.

    Groundwater is an increasingly important source of freshwater, especially where surface water resources are fully or over-allocated or becoming less reliable due to climate change. Groundwater reliance has created new challenges for sustainable management. This article examines how regional groundwater users coordinate and collaborate to manage shared groundwater resources, including attention to what drives collaboration. To identify and illustrate these facets, this article examines three geographically diverse cases of groundwater governance and management from the United States Sun Belt: Orange County Water District in southern California; Prescott Active Management Area in north-central Arizona; and the Central Florida Water Initiative in central Florida. These regions have different surface water laws, groundwater allocation and management laws and regulations, demographics, economics, topographies, and climate. These cases were selected because the Sun Belt faces similar pressures on groundwater due to historical and projected population growth and limited availability of usable surface water supplies. Collectively, they demonstrate groundwater governance trends in the United States, and illustrate distinctive features of regional groundwater management strategies. Our research shows how geophysical realities and state-level legislation have enabled and/or stimulated regions to develop groundwater management plans and strategies to address the specific issues associated with their groundwater resources. We find that litigation involvement and avoidance, along with the need to finance projects, are additional drivers of regional collaboration to manage groundwater. This case study underscores the importance of regionally coordinated and sustained efforts to address serious groundwater utilization challenges faced by the regions studied and around the world.

    Groundwater is an increasingly important source of freshwater, especially where surface water resources are fully or over-allocated or becoming less reliable due to climate change. Groundwater reliance has created new challenges for sustainable management. This article examines how regional groundwater users coordinate and collaborate to manage shared groundwater resources, including attention to what drives collaboration. To identify and illustrate these facets, this article examines three geographically diverse cases of groundwater governance and management from the United States Sun Belt: Orange County Water District in southern California; Prescott Active Management Area in north-central Arizona; and the Central Florida Water Initiative in central Florida. These regions have different surface water laws, groundwater allocation and management laws and regulations, demographics, economics, topographies, and climate. These cases were selected because the Sun Belt faces similar pressures on groundwater due to historical and projected population growth and limited availability of usable surface water supplies.

    The presence of openly gay soldiers does not undermine unit cohesion, according to a new statistical analysis of the Israel Defense Force (IDF). The study surveyed 417 male Israeli soldiers from 22 military installations. Statistical analysis of responses to the survey indicated that for both combat and non-combat units, the presence of openly gay troops in a unit had no relationship to the cohesiveness of the unit. Israel has allowed gays and lesbians to serve openly in the military since 1993.

    This study examines how pollutant linkage of contaminants will be influenced by predicted changes in precipitation and subsequent rainfall erosion of soils and spoils in the United Kingdom during the 21st century. Two contrasting regional climates were used in conjunction with 2 extreme emissions scenarios (low and high greenhouse gas emissions) to run the Revised Universal Soil Loss Equation 2 (RUSLE2) model for a case study that represents a high risk of pollutant linkage through water erosion. Results for the 2 scenarios and the 2 regions showed a significant and gradual increase in erosion rates with time as a consequence of climate change, by up to 32% for the southwest and 6.6% for the southeast regions by the 2080s. Revegetation of the site showed a dramatic reduction in predicted future amounts of sediment production and subsequent contaminant movement, well below existing levels. Limitations and future improvements of the methodology are discussed.

    High-resolution (downscaled) projections of future climate conditions are critical inputs to a wide variety of ecological and socioeconomic models and are created using numerous different approaches. Here, we conduct a sensitivity analysis of spatial predictions from climate envelope models for threatened and endangered vertebrates in the southeastern United States to determine whether two different downscaling approaches (with and without the use of a regional climate model) affect climate envelope model predictions when all other sources of variation are held constant. We found that prediction maps differed spatially between downscaling approaches and that the variation attributable to downscaling technique was comparable to variation between maps generated using different general circulation models (GCMs). Precipitation variables tended to show greater discrepancies between downscaling techniques than temperature variables, and for one GCM, there was evidence that more poorly resolved precipitation variables contributed relatively more to model uncertainty than more well-resolved variables. Our work suggests that ecological modelers requiring high-resolution climate projections should carefully consider the type of downscaling applied to the climate projections prior to their use in predictive ecological modeling. The uncertainty associated with alternative downscaling methods may rival that of other, more widely appreciated sources of variation, such as the general circulation model or emissions scenario with which future climate projections are created.

    Water quality monitoring is a cornerstone of environmental protection and ambient monitoring provides managers with the critical data they need to take informed action. Unlike site-specific monitoring that is at the heart of regulatory permit compliance, regional monitoring can provide an integrated, holistic view of the environment, allowing managers to obtain a more complete picture of natural variability and cumulative impacts, and more effectively prioritize management actions. By reviewing four long-standing regional monitoring programs that cover portions of all three coasts in the United States – Chesapeake Bay, Tampa Bay, Southern California Bight, and San Francisco Bay – important insights can be gleaned about the benefits that regional monitoring provides to managers. These insights include the underlying reasons that make regional monitoring programs successful, the challenges to maintain relevance and viability in the face of ever-changing technology, competing demands and shifting management priorities. The lessons learned can help other managers achieve similar successes as they seek to establish and reinvigorate their own monitoring programs.

    Globally, rivers and streams are highly altered by impoundments, diversions, and stream channelization associated with agricultural and water delivery needs. Climate change imposes additional challenges by further reducing discharge, introducing variability in seasonal precipitation patterns, and increasing temperatures. Collectively, these changes in a river or stream’s annual hydrology affects surface and groundwater dynamics, fluvial processes, and the linked aquatic and riparian responses, particularly in arid regions. Recognizing the inherent ecosystem services that riparian and aquatic habitats provide, society increasingly supports restoring the functionality of riparian and aquatic ecosystems.Given the wide range in types and scales of riparian impacts, approaches to riparian restoration can range from tactical, short-term, and site-specific efforts to strategic projects and long-term collaborations best pursued at the watershed scale. In the spirit of sharing information, the U.S. Geological Survey’s Grand Canyon Monitoring and Research Center convened a workshop June 23-25, 2015, in Flagstaff, Ariz. for practitioners in restoration science to share general principles, successful restoration practices, and discuss the challenges that face those practicing riparian restoration in the southwestern United States. Presenters from the Colorado River and the Rio Grande basins, offered their perspectives and experiences in restoration at the local, reach and watershed scale. Outcomes of the workshop include this Proceedings volume, which is composed of extended abstracts of most of the presentations given at the workshop, and recommendations or information needs identified by participants. The organization of the Proceedings follows a general progression from local scale restoration to river and watershed scale approaches, and finishes with restoration assessments and monitoring.

    Introduction: In any complex human system, human error is inevitable and shows that can’t be eliminated by blaming wrong doers. So with the aim of improving Intensive Care Units (ICU) reliability in hospitals, this research tries to identify and analyze ICU’s process failure modes at the point of systematic approach to errors. Methods: In this descriptive research, data was gathered qualitatively by observations, document reviews, and Focus Group Discussions (FGDs) with the process owners in two selected ICUs in Tehran in 2014. But, data analysis was quantitative, based on failures’ Risk Priority Number (RPN) at the base of Failure Modes and Effects Analysis (FMEA) method used. Besides, some causes of failures were analyzed by qualitative Eindhoven Classification Model (ECM). Results: Through FMEA methodology, 378 potential failure modes from 180 ICU activities in hospital A and 184 potential failures from 99 ICU activities in hospital B were identified and evaluated. Then with 90% reliability (RPN≥100), totally 18 failures in hospital A and 42 ones in hospital B were identified as non-acceptable risks and then their causes were analyzed by ECM. Conclusions: Applying of modified PFMEA for improving two selected ICUs’ processes reliability in two different kinds of hospitals shows that this method empowers staff to identify, evaluate, prioritize and analyze all potential failure modes and also make them eager to identify their causes, recommend corrective actions and even participate in improving process without feeling blamed by top management. Moreover, by combining FMEA and ECM, team members can easily identify failure causes at the point of health care perspectives. PMID:27157162

  6. “Build It and They Will Come?” A Case Study of the Use of a Wiki in a Higher Education Research Unit

    Full Text Available With collaborative web technologies such as wikis becoming increasingly popular in the workplace, this case study examined how workers at an education research unit within a graduate school of education perceive the wiki as a platform for communication and collaboration, and the extent to which they actually use a workplace wiki for that purpose. Twenty staff members, for whom a wiki was built, were surveyed, while records of their activities on the wiki over a 6-month period were retrieved and analyzed. Findings reveal that though most of these staff members have positive views towards the wiki as a space that can effectively promote information sharing and collaboration, they are not quite as enthusiastic about engaging the wiki as a medium for their daily collaborative work activities. The possible reasons for this discrepancy are discussed together with recommendations on the strategies similar organizations can adopt to help encourage and maximize wiki usage in the workplace.

    Full Text Available Professional ethics is a factor that is under the influence of external factors and with the help of individual conscience causes adherence in a person. As professional ethics is properly guided and strengthened by social or environmental elements, its effects will appear on the output or final product in a desirable way. The present study examines the social influential factors on individual’s level of professional ethics in the workplace. For this purpose, 400 workers in both branches of industrial townships of Ardabil participated in this study. The data for this study was collected from administering a researcher-made questionnaire (consisting of 78 questions, interview, and observation. The findings revealed that socio-cultural factors primarily and individual-personality factors secondarily, affect the person’s work ethics. In addition, social factors such as intimate relationship, gender, education, skill, income, religious belief, and job stability have a positive impact on a person's work ethics.

    There is growing awareness that the poor uptake of evidence in health care is not a knowledge-transfer problem but rather one of knowledge production. This issue calls for re-examination of the evidence produced and assumptions that underpin existing knowledge-to-action (KTA) activities. Accordingly, it has been advocated that KTA studies should treat research knowledge and local practical knowledge with analytical impartiality. The purpose of this case report is to illustrate the complexities in an evidence-informed improvement process of organized stroke care in a local rehabilitation setting. A participatory action approach was used to co-create knowledge and engage local therapists in a 2-way knowledge translation and multidirectional learning process. Evidence regarding rehabilitation stroke units was applied in a straightforward manner, as the setting met the criteria articulated in stroke unit reviews. Evidence on early supported discharge (ESD) could not be directly applied because of differences in target group and implementation environment between the local and reviewed settings. Early supported discharge was tailored to the needs of patients severely affected by stroke admitted to the local rehabilitation stroke unit by combining clinical and home rehabilitation (CCHR). Local therapists welcomed CCHR because it helped them make their task-specific training truly context specific. Key barriers to implementation were travel time, logistical problems, partitioning walls between financing streams, and legislative procedures. Improving local settings with available evidence is not a straightforward application process but rather a matter of searching, logical reasoning, and creatively working with heterogeneous knowledge sources in partnership with different stakeholders. Multiple organizational levels need to be addressed rather than focusing on therapists as sole site of change. © 2015 American Physical Therapy Association.

  11. Toward enhanced capability for detecting and predicting dust events in the western United States: the Arizona case study

    Dust aerosols affect human life, ecosystems, atmospheric chemistry and climate in various aspects. Some studies have revealed intensified dust activity in the western US during the past decades despite the weaker dust activity in non-US regions. It is important to extend the historical dust records, to better understand their temporal changes, and to use such information to improve the daily dust forecasting skill as well as the projection of future dust activity under the changing climate. This study develops dust records in Arizona in 2005-2013 using multiple observation data sets, including in situ measurements at the surface Air Quality System (AQS) and Interagency Monitoring of Protected Visual Environments (IMPROVE) sites, and level 2 deep blue aerosol product by the Moderate Resolution Imaging Spectroradiometer. The diurnal and inter-annual variability of identified dust events are shown related to observed weather patterns (e.g., wind and soil moisture) and surface conditions (e.g., land cover type and vegetation conditions), suggesting a potential for use of satellite soil moisture and land products to help interpret and predict dust activity. Backtrajectories computed using NOAA's Hybrid Single Particle Lagrangian Integrated Trajectory (HYSPLIT) model indicate that the Sonoran and Chihuahuan deserts are important dust source regions during identified dust events in Phoenix, Arizona. Finally, we assess the impact of a recent strong dust event on western US air quality, using various observational and modeling data sets, during a period with a stratospheric ozone intrusion event. The capability of the current US National Air Quality Forecasting Capability (NAQFC) Community Multi-scale Air Quality (CMAQ) modeling system to represent the magnitude and the temporal variability of aerosol concentrations is evaluated for this event. Directions for integrating observations to further improve dust emission modeling in CMAQ are also suggested.

    Full Text Available Today, organization cannot firmly survive without having a broad captive market. Rather, through value creation for customers and achieve their loyalty, we can maintain and increase the existing market share. Providing a specific product or service requires modern ideas and approaches to be applied in organizations. Resource limitations prevent organizations from being the best on all value creation contexts; so they must focus on some range of customer-centric values regarding the given customer groups; because customer needs will change as time goes by and it requires different kinds of values to be taken into consideration. In this research, organizational value creation effects on customer loyalty is studied by more recent and complete customer value model designed by Flint et al. (2010 [Flint et al. (2010. Customer value anticipation, customer satisfaction and loyalty: An empirical examination. Industrial Marketing Management, 40, 219-230]. In this regard, some questionnaires are distributed among a statistical population including 90 customers of Tehran Food Industries. Results show that organizational value creation affects on customer loyalty. Among effective factors, product quality has the most effects on organizational value creation following by product price, marketing and after-sales services.

    This study examined a nutrition education program consisting of two content sessions: food-label reading, and food pyramid guide. In each session two groups of nutrition interns utilized four teaching methods: role-play/video presentation/display, grocery store tour, overhead transparency and lecture, and power point lecture, among a group of (N = 29) ninth grade, high school students. The purpose was to determine the most effective method of delivering nutrition education to high school students. Analysis using the Kruskal Wallis One-way Analysis of Variance showed that the combination method of role-playing/video presentation/visual display was most effective in the food pyramid session (χ² = 8.13, p = .04). While this method was given the highest rank in the food-label reading session it was not statistically significant. These results show that a combination of methods classified as the teacher's style, is more effective than a style that involves a single teaching method.

    Full Text Available Making material available through learning management systems is standard practice in most universities, but this is generally seen as an adjunct to the ‘real’ teaching, that takes place in face-to-face classes. Lecture attendance is poor, and it is becoming increasingly difficult to engage students, both in the material being taught and campus life. This paper describes the redevelopment of a large course in scientific practice and communication that is compulsory for all science students studying at our Melbourne and Malaysian campuses, or by distance education. Working with an educational designer, a blended learning methodology was developed, converting the environment provided by the learning management system into a teaching space, rather than a filing system. To ensure focus, topics are clustered into themes with a ‘question of the week’, a pre-class stimulus and follow up activities. The content of the course did not change, but by restructuring the delivery using educationally relevant design techniques, the content was contextualised resulting in an integrated learning experience. Students are more engaged intellectually, and lecture attendance has improved. The approach we describe here is a simple and effective approach to bringing this university’s teaching and learning into the 21st century.

    Tuberculosis (TB) remains a highly prevalent and potentially severe disease. However, since 2002 the annual incidence has been decreasing both worldwide and in Spain, where the incidence varies widely between regions. The main objective of this study is to describe the experience of a monographic TB unit in a second level hospital. A descriptive study was carried out which included all cases of TB diagnosed in a monographic unit of a secondary hospital between 2003 and 2011. Demographic, clinical, epidemiological and microbiological data were recorded. We analyzed 500 TB cases and found an increasing annual incidence in all subgroups, including native and immigrant populations. Most cases (63.8%) were male, with a median age of 36 years (range 8 months-90 years). In total, 39.8% of patients were foreign born. Coinfection with human immunodeficiency virus was found in 11% of cases. The pulmonary form was most frequently diagnosed (63.8%). Overall mortality was 5.8% with no significant differences between groups (including foreign born and human immunodeficiency virus positive patients). Although TB incidence is globally decreasing, in our study we found an increasing number of cases in recent years in all subgroups, which can be explained by this being a monographic unit with an intensive contact tracing program.

    Full Text Available Abstract Background Ventilator-associated pneumonia (VAP which is an important part of all nosocomial infections in intensive care unit (ICU is a serious illness with substantial morbidity and mortality, and increases costs of hospital care. We aimed to evaluate costs and risk factors for VAP in adult ICU. Methods This is a-three year retrospective case-control study. The data were collected between 01 January 2000 and 31 December 2002. During the study period, 132 patients were diagnosed as nosocomial pneumonia of 731 adult medical-surgical ICU patients. Of these only 37 VAP patients were assessed, and multiple nosocomially infected patients were excluded from the study. Sixty non-infected ICU patients were chosen as control patients. Results Median length of stay in ICU in patients with VAP and without were 8.0 (IQR: 6.5 and 2.5 (IQR: 2.0 days respectively (P Conclusion Respiratory failure, coma, depressed consciousness, enteral feeding and length of stay are independent risk factors for developing VAP. The cost of VAP is approximately five-fold higher than non-infected patients.

    Full Text Available One of the necessary actions in many organizations is to reduce the number of workers in an attempt to restructure business activities. However, layoff could have negative consequences since many employees may decide to leave since they lose their tolerance. The layoff must be accompanied with some supportive plans to reduce stress among the remaining workers and increase their commitment for long-term work. The present study of this paper considers the effects of layoff on job satisfaction and commitment among the remaining employees of a detergent producer unit. The results indicate that a good supportive program including wage increase, family support, health care plans, etc. could significantly improve employee long-term commitments and it leads to job satisfaction.

    Full Text Available Non-alcoholic fatty liver disease (NAFLD is the most common cause of chronic liver disease in children, with prevalence rising alongside childhood obesity rates. This study aimed to characterise the habitual diet and activity behaviours of children with NAFLD compared to obese children without liver disease in the United Kingdom (UK.

Groups were well matched for age and gender. Obese children had higher BMI z-scores (p = 0.006 and BMI centiles (p = 0.002 than participants with NAFLD. After adjusting for multiple hypotheses testing and controlling for differences in BMI, no differences in macro- or micronutrient intake were observed as assessed using either 24-h recall or 7-day FAD (p > 0.001. Under-reporting was prevalent (NAFLD 75%, Obese Control 87%: p = 0.15. Restrained eating behaviours were significantly higher in the NAFLD group (p = 0.005, who also recorded more steps per day than the obese controls (p = 0.01. In conclusion, this is the first study to assess dietary and activity patterns in a UK paediatric NAFLD population. Only a minority of cases and controls were meeting current dietary and physical activity recommendations. Our findings do not support development of specific dietary/ physical activity guidelines for children with NAFLD; promoting adherence with current general paediatric recommendations for health should remain the focus of clinical management.

    Numerous studies have examined the elasticities of electricity demand---residential as well as commercial and industrial---in the private sector. However, no one appears to have examined the behavior of the public sector demand. This study aims to fill that gap and to provide insights into the electricity demand in the public sector, using the U.S. Navy bases as a case study. This study examines electricity demand data of 38 Navy activities within the United States for a 16-year time period from 1985 through 2000. The Navy maintains a highly diverse shore infrastructure to conduct its mission and to support the fleet. The types of shore facilities include shipyards, air stations, aviation depots, hospital, and many others. These Navy activities are analogous to commercial or industrial organizations in the private sector. In this study, I used a number of analytical approaches to estimate short-run and long-run elasticities of electricity demand. Estimation using pooled data was rejected because it failed the test for homogeneity. Estimation using the time series data of each Navy activity had several wrong signs for coefficients. The Stein-rule estimator did not differ significantly from the separate cross-section estimates because of the strong rejection of the homogeneity assumption. The iterative Bayesian shrinkage estimator provided the most reasonable results. The empirical findings from this study are as follows. First, the Navy's electricity demand is price elastic. Second, the price elasticities appear to be lower than those of the private sector. The short-run price elasticities for the Navy activities ranged from -0.083 to -0.157. The long-run price elasticities ranged from -0.151 to -0.769.

    Landslide susceptibility assessment forms the basis of any hazard mapping, which is one of the essential parts of quantitative risk mapping. For the same study area, different susceptibility maps can be achieved depending on the type of susceptibility mapping methods, mapping unit, and scale. In the Ubaye Valley (South French Alps), we investigate the effect of resolution and method of production of the DEM to delineate slope units for landslide susceptibility mapping method. Slope units delineation has been processed using multiple combinations of circular variance and minimum area size values, which are the input parameters for a new software for terrain partitioning. We rely on this method taking into account homogeneity of aspect direction inside each unit and inhomogeneity between different units. We computed slope units delineation for 5, 10 and 25 meters resolution DEM, and investigate statistical distributions of morphometric variables within the different polygons. Then, for each different slope units partitioning, we calibrated a landslide susceptibility model, considering landslide bodies and scarps as a dependent variable (binary response). This work aims to analyse the role of DEM resolution on slope-units delineation for landslide susceptibility assessment. Area Under the Curve of the Receiver Operating Characteristic is investigated for the susceptibility model calculations. In addition, we analysed further the performance of the Logistic Regression Model by looking at the percentage of significant variable in the statistical analyses. Results show that smaller slope units have a better chance of containing a smaller number of thematic and morphometric variables, allowing for an easier classification. Reliability of the models according to the DEM resolution considered as well as scarp area and landslides bodies presence/absence as dependent variable are discussed.

    Full Text Available This case study was developed from an actual scenario by Dr. Steve Leybourne of Boston University.  The case documents the historical evolution of an organization, and has been used successfully in courses dealing with organizational and cultural change, and the utilization of ‘soft skills’ in project-based management. This is a short case, ideal for classroom use and discussion.  The issues are easily accessible to students, and there is a single wide ranging question that allows for the inclusion of many issues surrounding strategic decision-making, and behavioural and cultural change. Alpha was one of the earlier companies in the USA to invest in large, edge-of-town superstores, with plentiful free vehicle parking, selling food and related household products. Alpha was created in the 1950s as a subsidiary of a major publicly quoted retail group.  It started business by opening a string of very large discount stores in converted industrial and warehouse premises in the south of the United States. In the early days shoppers were offered a limited range of very competitively priced products. When Alpha went public in 1981 it was the fourth largest food retailer in the US, selling an ever-widening range of food and non-food products.  Its success continued to be based on high volume, low margins and good value for money, under the slogan of ‘Alpha Price.’

  8. Changing policy framing as a deliberate strategy for public health advocacy: a qualitative policy case study of minimum unit pricing of alcohol.

    Scotland is the first country in the world to pass legislation introducing a minimum unit price (MUP) for alcohol in an attempt to reduce consumption and associated harms by increasing the price of the cheapest alcohol. We investigated the competing ways in which policy stakeholders presented the debate. We then established whether a change in framing helped explain the policy's emergence. We conducted a detailed policy case study through analysis of evidence submitted to the Scottish parliament, and in-depth, one-to-one interviews (n = 36) with politicians, civil servants, advocates, researchers, and industry representatives. Public- and voluntary-sector stakeholders tended to support MUP, while industry representatives were more divided. Two markedly different ways of presenting alcohol as a policy problem were evident. Critics of MUP (all of whom were related to industry) emphasized social disorder issues, particularly among young people, and hence argued for targeted approaches. In contrast, advocates for MUP (with the exception of those in industry) focused on alcohol as a health issue arising from overconsumption at a population level, thus suggesting that population-based interventions were necessary. Industry stakeholders favoring MUP adopted a hybrid framing, maintaining several aspects of the critical framing. Our interview data showed that public health advocates worked hard to redefine the policy issue by deliberately presenting a consistent alternative framing. Framing alcohol policy as a broad, multisectoral, public health issue that requires a whole-population approach has been crucial to enabling policymakers to seriously consider MUP, and public health advocates intentionally presented alcohol policy in this way. This reframing helped prioritize public health considerations in the policy debate and represents a deliberate strategy for consideration by those advocating for policy change around the world and in other public health areas. © 2014

    This article describes case study research for nursing and healthcare practice. Case study research offers the researcher an approach by which a phenomenon can be investigated from multiple perspectives within a bounded context, allowing the researcher to provide a 'thick' description of the phenomenon. Although case study research is a flexible approach for the investigation of complex nursing and healthcare issues, it has methodological challenges, often associated with the multiple methods used in individual studies. These are explored through examples of case study research carried out in practice and education settings. An overview of what constitutes 'good' case study research is proposed.

    Atrial fibrillation (AF) is one of the most frequent arrhythmias in clinical practice. Previous studies have reported the influence of AF on patients with heart failure (HF). The effect of AF on the non-HF critically ill patients in a medical intensive care unit (ICU) remains largely unclear. The study aimed to investigate the impact of AF presenting on ICU admission on the weaning outcome of non-HF mechanically ventilated patients in a medical ICU.A retrospective observational case-control study was conducted over a 1-year period in a medical ICU at Taipei Veterans General Hospital, a tertiary medical center in north Taiwan. Non-HF mechanically ventilated patients who were successful in their spontaneous breathing trial and underwent ventilator discontinuation were enrolled. The primary outcome measure was the ventilator status after the first episode of ventilator discontinuation.A total of 285 non-HF patients enrolled were divided into AF (n = 62) and non-AF (n = 223) groups. Compared with the non-AF patients, the AF patients were significantly associated with old age (P = 0.002), a higher rate of acute respiratory distress syndrome causing respiratory failure (P = 0.015), a higher percentage of sepsis before liberation from mechanical ventilation (MV) (P = 0.004), and a higher serum level of blood urea nitrogen on the day of liberation from MV (P = 0.003). Multivariate logistic regression analysis demonstrated that AF independently increased the risk of weaning failure [adjusted odds ratio (AOR), 3.268; 95% confidence interval (CI), 1.254-8.517; P = 0.015]. Furthermore, the AF patients were found to be independently associated with a high rate of ventilator dependence (log rank test, P = 0.026), prolonged total ventilator use (AOR, 1.979; 95% CI, 1.032-3.794; P = 0.040), increased length of ICU stay (AOR, 2.256; 95% CI, 1.049-4.849; P = 0.037), increased length of hospital stay (AOR, 2.921; 95% CI, 1.363-6.260; P = 0

    Full Text Available In Turkey, the understanding of planning focused on timber production has given its place on Multiple Use Management (MUM. Because the whole infrastructure of forestry with inventory system leading the way depends on timber production, some cases of bottle neck are expected during the transition period. Database design, probably the most important stage during the transition to MUM, together with the digital basic maps making up the basis of this infrastructure constitute the main point of this article. Firstly, the forest management philosophy of Turkey in the past was shortly touched upon in the article. Ecosystem Based Multiple Use Forest Management (EBMUFM approaches was briefly introduced. The second stage of the process of EBMUFM, database design was described by examining the classical planning infrastructure and the coverage to be produced and consumed were suggested in the form of lists. At the application stage, two different geographical databases were established with GIS in Balcı Planning Unit of the years 1984 and 2006. Following that the related basic maps are produced. Timely diversity of the planning unit of 20 years is put forward comparatively with regard to the stand parameters such as tree types, age class, development stage, canopy closure, mixture, volume and increment.

    Full Text Available Objective: Neonatal pneumothoraces are associated with high mortality. Prompt recognition to minimize its complications is paramount for ultimate outcome of these babies.Methods: A retrospective case series study was carried out at Aga khan University Hospital, from January 2010 to December 2010 to determine the etiology and outcome of neonates with pneumothorax in a neonatal tertiary care unit.Results: Ten neonates diagnosed radiologically with pneumothoraces were included. M: F ratio was 1:2.3. Birth weight ranged from 1750-3600 grams with a mean of 2100 grams. The occurrence of pneumothoraces was 50% on the left side, 20% on right, and 30% were bilateral. Primary etiology included pneumonia and sepsis (30%, hyaline membrane disease (20%, meconium aspiration syndrome (20% and congenital diaphragmatic hernia (10%. Spontaneous pneumothoraces were present in 20% of cases. In our study, the incidence of neonatal pneumothoraces was 2.5/1000 births compared to 10-15/1000 in Denmark, 10-20/1000 in Turkey and 6.3/1000 from Vermont Oxford Group. Despite the small number of cases, one incidental finding was the occurrence of pneumothorax, which declined in elective cesarean section after 37 weeks gestation i.e., 1.3 of 1000 births. Mortality was 60% determined mainly by the primary etiology and other co-morbid conditions.Conclusion: The study showed a higher number of mortality cases (60%. Although, it was difficult to draw a conclusion from the limited number of cases, there may be a benefit on neonatal respiratory outcome to be obtained by better selection of mothers and by waiting until 37 weeks before performing elective cesarean section. Adequate clinician training in soft ventilation strategies will reduce the occurrence of pneumothoraces.

    Fish consumption advisories are used to inform citizens in the United States about noncommercial game fish with hazardous levels of methylmercury (MeHg). The US Environmental Protection Agency (USEPA) suggests issuing a fish consumption advisory when concentrations of MeHg in fish exceed a human health screening value of 300 ng/g. However, states have authority to develop their own systems for issuing fish consumption advisories for MeHg. Five states in the south central United States (Arkansas, Louisiana, Mississippi, Oklahoma, and Texas) issue advisories for the general human population when concentrations of MeHg exceed 700 ng/g to 1000 ng/g. The objective of the present study was to estimate the increase in fish consumption advisories that would occur if these states followed USEPA recommendations. The authors used the National Descriptive Model of Mercury in Fish to estimate the mercury concentrations in 5 size categories of largemouth bass-equivalent fish at 766 lentic and lotic sites within the 5 states. The authors found that states in this region have not issued site-specific fish consumption advisories for most of the water bodies that would have such advisories if USEPA recommendations were followed. One outcome of the present study may be to stimulate discussion between scientists and policy makers at the federal and state levels about appropriate screening values to protect the public from the health hazards of consuming MeHg-contaminated game fish.

    Full Text Available In a globalization scenario, uncertainty and high competitive edge between the companies, every manager needs to make decisions that bring competitive advantage to his/her organization. These decisions are increasingly complex, which demands more rapid and precise information to allow efficient decision-making. It is in this scenario that Information Systems (IS have gained importance in the decision-making process. Yet, many of these IS may not be adequate to the manager’s needs. This study aims to identify the perception of the managers of an Organizational Unit at an oil and derivatives company about the support given by ISs regarding their decision making. To obtain the expected results, a questionnaire based on the critical factors involved in IS quality and directed to the managers of the Organizational Unit. Results of this study will enable professionals responsible for developing ISs, as well as managers and those working with these systems to identify strengths and weaknesses of existing systems.

    Sociologists designed a random sampling study based on an adaptation of the Housing Unit Method and the local expert method to determine the socioeconomic features of a 3 unincorporated rural communities near Yucca Mountain, Nevada which scientists will use to conduct a comprehensive impact analysis of the proposed geologic nuclear waste repository at Yucca Mountain, about 90 miles northwest of Las Vegas. Electrical company representatives indicated the location and type of housing with all up to date electrical connections in southern Nye county. This information was included in the housing unit file made from utility records from each community. After determining the sample size needed, households were randomly chosen from each file (326 Amargosa Valley, 672 Beatty, and 3224 Pahrump). Meter readers from the local utility companies were the local experts. 2 local experts worked together to authenticate the accuracy of recorded data which included number of person in the household as of July 15, 1990 and age and gender of each member. Data accuracy was tested and it was found that the 1990 US Census counts were within the relatively narrow 95% confidence intervals. The mean width was 7.2% of the estimated population, thus the estimates were meaningful. The estimates were too low for Pahrump (7190 vs. 7425) and Amargosa Valley (841 vs. 853), however. This may have been due to recent in-migration from the Las Vegas Valley. Age and gender accuracy could not be tested since the 1990 census data were not yet ready. Nevertheless, it is believed that this procedure can obtain very accurate estimates.

  8. The science case of WISH-Spec, an Integral-field unit for the WISH telescope to study the first populations of galaxies in the universe

    Science.gov (United States)

    Burgarella, Denis

    2015-08-01

    WISH is a new space science mission concept whose primary goal is to study the first galaxies in the early universe. WISH will be a 1.5m telescope equipped with a 1000 arcmin2 wide-field Near-IR camera that would fly in ~2020 in order to conduct unique ultra-deep and wide-area sky surveys in the wavelength range 1-5 micron. A spectroscopic mode (Integral-Field Unit) in the same Near-IR range is also planned. The primary science goal of WISH mission is to push the high-redshift frontier beyond the epoch of reionization by utilizing its unique imaging capability and the dedicated survey strategy. Which spectral range should we select to optimize the detection of very high-redshift (i.e., z > 5) galaxies ? In the rest-frame Far-UV or in the rest-frame Far-IR? In a recent paper, Burgarella et al. (2013) showed that the Far-UV dust attenuation (AFUV) reaches the same level at z ~ 3 than at z = 0 . This suggest that the early universe would be better studied in the rest-frame Far-UV. At z > 5, this Far-UV range moves into the Near-IR (1 - 5um) which is WISH’s preferred spectral range. The baseline of WISH-Spec is a 1x1 arcmin2 Integral-Field Unit (IFU) using slicers. WISH-Spec could observe in a parallel mode which translates into spectroscopic exposure times as long as the telescope lifetime. WISH features two 100-deg2 and 1000-deg2 surveys. However, WISHSpec will allow to acquire very large samples of high-redshift and primordial galaxies by combining spectroscopic detections within total (non contiguous) 1-deg2 and 10-deg2 fields of views. Therefore, the first strong advantage of WISHSpec wrt JWST is that 10^4 - 10^5 faint emission-line galaxies in 1 deg2 and 10^3 - 10^6 bright emission-line galaxies in 10 deg2 in the redshift range 3 < z < 8 will be detected.

  9. Identifying potential areas for biofuel production and evaluating the environmental effects: a case study of the James River Basin in the Midwestern United States

    2012-01-01

    Biofuels are now an important resource in the United States because of the Energy Independence and Security Act of 2007. Both increased corn growth for ethanol production and perennial dedicated energy crop growth for cellulosic feedstocks are potential sources to meet the rising demand for biofuels. However, these measures may cause adverse environmental consequences that are not yet fully understood. This study 1) evaluates the long-term impacts of increased frequency of corn in the crop rotation system on water quantity and quality as well as soil fertility in the James River Basin and 2) identifies potential grasslands for cultivating bioenergy crops (e.g. switchgrass), estimating the water quality impacts. We selected the soil and water assessment tool, a physically based multidisciplinary model, as the modeling approach to simulate a series of biofuel production scenarios involving crop rotation and land cover changes. The model simulations with different crop rotation scenarios indicate that decreases in water yield and soil nitrate nitrogen (NO3-N) concentration along with an increase in NO3-N load to stream water could justify serious concerns regarding increased corn rotations in this basin. Simulations with land cover change scenarios helped us spatially classify the grasslands in terms of biomass productivity and nitrogen loads, and we further derived the relationship of biomass production targets and the resulting nitrogen loads against switchgrass planting acreages. The suggested economically efficient (planting acreage) and environmentally friendly (water quality) planting locations and acreages can be a valuable guide for cultivating switchgrass in this basin. This information, along with the projected environmental costs (i.e. reduced water yield and increased nitrogen load), can contribute to decision support tools for land managers to seek the sustainability of biofuel development in this region.

    Men are at a higher risk of developing both squamous cell carcinoma (SCC) and basal cell carcinoma (BCC) than women, but there is emerging evidence that women may be experiencing greater increases in the incidence rates of these malignancies than men. One possible explanation is the expanding use of sex steroids among women, although only a few studies have examined this hypothesis. As part of a population-based, case-control study of women in New Hampshire, USA, we sought to evaluate the risk of SCC, BCC, and early-onset BCC in relation to exogenous and endogenous sex hormones. We found that oral contraceptive (OC) use was associated with an increased risk of SCC (OR = 1.4, 95% CI = 1.1-1.8) and BCC (OR = 1.4, 95% CI = 1.0-1.8), particularly high estrogen dose (>50 mg) OC use. Hormone replacement therapy (HRT) use also related to SCC, with an elevated OR largely for progestin use (OR = 1.4, 95% CI = 1.1-1.8). Additionally, both OC use and combination HRT use were associated with more aggressive BCC subtypes. In contrast, menstrual and reproductive history did not appear to influence keratinocyte cancer risk in our data. Our findings provide evidence that use of sex steroids may enhance risk of keratinocyte cancer.

  11. Research on sequence stratigraphy, hydrogeological units and commingled drainage associated with coalbed methane production: a case study in Zhuzang syncline of Guizhou province, China

    Exploitation of coalbed methane (CBM) involves groundwater extraction to depressurize coal reservoirs. This can involve groundwater extraction from multiple coal seams (commingled drainage). Interlayer interferences, caused by heterogeneity of hydrodynamic fields of the different coal gas reservoirs, can restrain CBM production. Understanding of the hydrogeological characteristics of each reservoir, inseparable from characteristics of the sequence stratigraphic framework, is critical for CBM exploration. Analysis of Zhuzang syncline in Guizhou province, China, found gas- and water-blocking strata near the maximum flooding surface in the upper part of each third-order stratigraphic sequence; thus, the hydrogeological units were divided vertically (SQ4, SQ3, SQ2 and SQ1) by the boundaries of the third-order sequence. The commingled-drainage CBM wells were analyzed by numerical simulation and Extenics theory, on the basis of characteristics of the hydrogeological units. Gas content, reservoir pressure and hydrodynamic parameters were found to vary between the hydrogeological units. The interlayer interference was not obvious where there was commingled drainage within single hydrogeological units with similar hydrodynamic force; this was validated by observing the consistent pressure decrease within each reservoir using historical matching. Since the source of drainage water varied from stratum SQ3 to SQ4 (containing lower hydrodynamic force compared to SQ3), it was obvious that groundwater extraction from SQ4 was restrained by SQ3, by showing obvious interlayer interference and restrained CBM production during commingled drainage across the different hydrogeological units. Reservoirs within each single hydrogeological unit tend to obtain higher CBM yield, thus take priority for commingled drainage.

    Exploitation of coalbed methane (CBM) involves groundwater extraction to depressurize coal reservoirs. This can involve groundwater extraction from multiple coal seams (commingled drainage). Interlayer interferences, caused by heterogeneity of hydrodynamic fields of the different coal gas reservoirs, can restrain CBM production. Understanding of the hydrogeological characteristics of each reservoir, inseparable from characteristics of the sequence stratigraphic framework, is critical for CBM exploration. Analysis of Zhuzang syncline in Guizhou province, China, found gas- and water-blocking strata near the maximum flooding surface in the upper part of each third-order stratigraphic sequence; thus, the hydrogeological units were divided vertically (SQ4, SQ3, SQ2 and SQ1) by the boundaries of the third-order sequence. The commingled-drainage CBM wells were analyzed by numerical simulation and Extenics theory, on the basis of characteristics of the hydrogeological units. Gas content, reservoir pressure and hydrodynamic parameters were found to vary between the hydrogeological units. The interlayer interference was not obvious where there was commingled drainage within single hydrogeological units with similar hydrodynamic force; this was validated by observing the consistent pressure decrease within each reservoir using historical matching. Since the source of drainage water varied from stratum SQ3 to SQ4 (containing lower hydrodynamic force compared to SQ3), it was obvious that groundwater extraction from SQ4 was restrained by SQ3, by showing obvious interlayer interference and restrained CBM production during commingled drainage across the different hydrogeological units. Reservoirs within each single hydrogeological unit tend to obtain higher CBM yield, thus take priority for commingled drainage.

  13. Youth action research in the marine environment: A case study analysis of selected education projects in Hawai'i, United States of America

    Zicus, Sandra A.

    The marine environment has always been extremely important to the human inhabitants of the Hawaiian Islands. Today, the ocean environment around Hawai'i is no less important, but it is far more threatened. Coastal and urban development, overfishing, introduction of alien species, and other commercial and recreational uses pose serious risks to coastal and marine ecosystems. There is a recognized need for greater public awareness and understanding of the importance of marine and coastal ecosystems. Involving children actively in the care and management of community resources is an essential factor for long-term societal change in environmental attitudes and behavior. Agencies and organizations in Hawai'i offer a wide range of marine education programs and materials aimed at children. However, there has been little assessment of their overall effectiveness, or analysis of factors that encourage or impede their success. The goal of this research was to begin to address this gap. The first stage of the research examined the perceptions and attitudes of Hawai'i resource managers and educators toward youth involvement in coastal and marine protection, and to answer the question "What is currently being done and by whom?" The second stage examined in detail three different programs that represent a range of approaches and age levels, and include two public charter schools (one elementary and one high school) and a nonprofit after-school program that drew youth from four area high schools. The case study research was conducted over the course of the 2001--2002 school year by means of observations, participant-observations, interviews, focus groups, and reviews of written and electronic media. The case studies were exploratory in nature and differed in their settings, age groups, administration, size, and focus. However, an analysis using the assessment rubric revealed broad patterns common to all three projects. This allowed the development of analytical generalizations

    Full Text Available The United States of America, a home to immigrants and refugees from various cultures and corners of the world continues to encounter waves of mass immigration. Some immigrated due to well-founded fears of persecution (i.e. religious, political, race, or social group or economic hardships. Others immigrated to, reunite with family members, seek economic and education opportunities, and better standards of living. Notwithstanding their channels of admission or entry and their pivotal role in enriching the culture and the economy of the United States of America, many confront several health and lifestyle related challenges as they acculturate and integrate into the mainstream of American life and culture. Although many individuals and organizations have created numerous programs and activities to help ease these difficulties, minimal documentation is available on the involvement and engagement of the non-traditional work force, such as the lay health cultural brokers.

  20. The impact of science methods courses on preservice elementary teachers' science teaching self-efficacy beliefs: Case studies from Turkey and the United States

    Bursal, Murat

    Four case studies in two American and two Turkish science methods classrooms were conducted to investigate the changes in preservice elementary teachers' personal science teaching efficacy (PSTE) beliefs during their course periods. The findings indicated that while Turkish preservice elementary teachers (TR sample) started the science methods course semester with higher PSTE than their American peers (US sample), due to a significant increase in the US sample's and an insignificant decline in the TR sample's PSTE scores, both groups completed the science methods course with similar PSTE levels. Consistent with Bandura's social cognitive theory, describing four major sources of self-efficacy, the inclusion of mastery experiences (inquiry activities and elementary school micro-teaching experiences) and vicarious experiences (observation of course instructor and supervisor elementary teacher) into the science methods course, providing positive social persuasion (positive appraisal from the instructor and classmates), and improving physiological states (reduced science anxiety and positive attitudes toward becoming elementary school teachers), were found to contribute to the significant enhancement of the US sample's PSTE beliefs. For the TR sample, although some of the above sources were present, the lack of student teaching experiences and inservice teacher observations, as well as the TR samples' negative attitudes toward becoming elementary school teachers and a lack of positive classroom support were found to make Turkish preservice teachers rely mostly on their mastery in science concepts, and therefore resulted in not benefiting from their science methods course, in terms of enhancing their PSTE beliefs. Calls for reforms in the Turkish education system that will include more mastery experiences in the science methods courses and provide more flexibility for students to choose their high school majors and college programs, and switch between them are made.

    Improved indoor air quality (IAQ) is one of the critical components of green building design. Green building tax credit (e.g., New York State Green Building Tax Credit (GBTC)) and certification programs (e.g., Leadership in Energy & Environmental Design (LEED)) require indoor air quality measures and compliance with allowable maximum concentrations of common indoor air pollutants. It is not yet entirely clear whether compliance with these programs results in improved IAQ and ultimately human health. As a case in point, annual indoor air quality measurements were conducted in a residential green high-rise building for five consecutive years by an industrial hygiene contractor to comply with the building's GBTC requirements. The implementation of green design measures resulted in better IAQ compared to data in references of conventional homes for some parameters, but could not be confirmed for others. Relative humidity and carbon dioxide were satisfactory according to existing standards. Formaldehyde levels during four out of five years were below the most recent proposed exposure limits found in the literature. To some degree, particulate matter (PM) levels were lower than that in studies from conventional residential buildings. Concentrations of Volatile Organic Compounds (VOCs) with known permissible exposure limits were below levels known to cause chronic health effects, but their concentrations were inconclusive regarding cancer health effects due to relatively high detection limits. Although measured indoor air parameters met all IAQ maximum allowable concentrations in GBTC and applicable LEED requirements at the time of sampling, we argue that these measurements were not sufficient to assess IAQ comprehensively because more sensitive sampling/analytical methods for PM and VOCs are needed; in addition, there is a need for a formal process to ensure rigor and adequacy of sampling and analysis methods. Also, we suggest that a comprehensive IAQ assessment should

The analytical error model, using the maximum relative representation error (MRRE and the average relative representation error (ARRE, is developed to obtain the maximum and average output errors for the bit-width reduced FPUs. After the development of the analytical error model, the bit-width reduced FPUs and an NN are designed using MATLAB and VHDL. Finally, the analytical (MATLAB results, along with the experimental (VHDL results, are compared. The analytical results and the experimental results show conformity of shape. We demonstrate that incremented reductions in the number of bits used can produce significant cost reductions including area, speed, and power.

    In this paper the feasibility of adopting Graphic Processor Units towards real-time emotion aware computing is investigated for boosting the time consuming computations employed in such applications. The proposed methodology was employed in analysis of encephalographic and electrodermal data gathered when participants passively viewed emotional evocative stimuli. The GPU effectiveness when processing electroencephalographic and electrodermal recordings is demonstrated by comparing the execution time of chaos/complexity analysis through nonlinear dynamics (multi-channel correlation dimension/D2) and signal processing algorithms (computation of skin conductance level/SCL) into various popular programming environments. Apart from the beneficial role of parallel programming, the adoption of special design techniques regarding memory management may further enhance the time minimization which approximates a factor of 30 in comparison with ANSI C language (single-core sequential execution). Therefore, the use of GPU parallel capabilities offers a reliable and robust solution for real-time sensing the user's affective state.

    Emergent discourses of social responsibility and accountability have in part fuelled the expansion of distributed medical education (DME). In addition to its potential for redressing physician maldistribution, DME has conferred multiple unexpected educational benefits. In several countries, its recent rise has occurred around the boundaries of traditional medical education practices. Canada has been no exception, with DME proliferating against a backdrop of its longstanding central node, the clinical teaching unit (CTU). The CTU first appeared just over 50 years ago with its position in Canadian health care largely taken-for-granted. Given the increasing prominence of DME, however, it is timely to reconsider what the place of tertiary centre-based practices such as the CTU might be in shifting medical education systems. From a genealogical perspective, it becomes clear that the CTU did not just "happen". Rather, its creation was made possible by multiple interrelated cultural, social, and political changes in Canadian society that, while subtle, are powerfully influential. Making them visible offers a better opportunity to harmonize the benefits of longstanding entities such as the CTU with novel practices such as DME. In so doing, the medical education field may sidestep the pitfalls of investing significant resources that may only produce superficial changes while unwittingly obstructing deeper transformations and improvements. Although this work is refracted through a Canadian prism, reconceptualizing the overall design of medical education systems to take advantage of both tradition and innovation is a persistent challenge across the international spectrum, resistant to tests of time and constraints of context.

    Full Text Available The Health Service Waste Management is a set of technical and legal procedures for waste management in any type of health facilities. It is known about the limited resources, so reducing environmental costs can contribute to the management of hospital costs. The objective was to estimate the cost of the phases of HSWM to the Intensive Care Unit for public service. Data collecting was done through a script of questions and observations on site at the Emilio Ribas Infectious Diseases Institute in Sao Paulo. The ABC costing method was used. The most costly step was wrapping (40.68%, followed by segregation (40.17%, which is justified by both being associated with health workers’ salaries. The daily cost of the management of health care waste from segregation to final disposal in the ICU was R$ 4,288.81 a day, being R$ 314.80/bed-patient/day. To know the cost of an activity allows for the analysis of strategies for price negotiation. Health care waste is little remembered when pricing a daily ICU, many managers believe this value to be irrelevant; but< if not measured, it may bring losses to the institution.

  11. A new concept of irrigation response units for effective management of surface and groundwater resources: a case study from the multi-country Fergana Valley, Central Asia

    2016-09-09

    When estimating canal water supplies for large-scale irrigation schemes and especially in arid regions worldwide, the impact of all factors affecting the gross irrigation requirements (GIR) are not properly accounted for, which results in inefficient use of precious freshwater resources. This research shows that the concept of irrigation response units (IRU)—areas having unique combinations of factors effecting the GIR—allows for more precise estimates of GIR. An overlay analysis of soil texture and salinity, depth and salinity of groundwater, cropping patterns and irrigation methods was performed in a GIS environment, which yielded a total of 17 IRUs combinations of the Oktepa Zilol Chashmasi water consumers’ association in multi-country Fergana Valley, Central Asia. Groundwater contribution, leaching requirements, losses in the irrigation system through field application and conveyance and effective rainfall were included in GIR estimates. The GIR varied significantly among IRUs [average of 851 mm (±143 mm)] with a maximum (1051 mm) in IRU-12 and a minimum (629 mm) in IRUs-15, 16. Owing to varying groundwater levels in each IRU, the groundwater contribution played a key role in the estimation of the GIR. The maximum groundwater contribution occurred in IRUs dominated by cotton–fallow rotations as evidenced by an average value of 159 mm but a maximum of 254 mm and a minimum of 97 mm. Percolation losses depended on irrigation methods for different crops in their respective IRUs. The novel approach can guide water managers in this and similar regions to increase the accuracy of irrigation demands based on all the factor effecting the GIR. © 2016 Springer-Verlag Berlin Heidelberg

    Rapid urbanisation coupled with climate change poses a significant threat of increased flooding in urban locations around the world. In the UK there is a lack of joined up science and monitoring data to support model development and management decisions required for a rapidly growing population. Here, we present the findings from a multi-disciplinary research project entitled POLLCURB involving a combination of both monitoring and modelling approaches, including participatory citizen science, to evaluate impacts of urbanisation and climate change on flooding and water quality in the Thames basin, United Kingdom. Empirical analysis of five years of monitoring data in intensely monitored sub-catchments reveals the degree to which urban land-use impacts upon hydrological and water quality response. Analysis reveals hydrological impacts do not always follow the expected urban gradient due to intra-catchment differences in hydraulic functions. Statistical detection and attribution techniques are used to assess long-term river data, highlighting strong signals of urban growth after climate variability is accounted for. Historical land-use change mapping of the Thames basin using remote sensing shows growth in urban coverage from around 13% (1980's) to 15% (2015) and was used to develop and train a cellular automata model. Projections of a business-as-usual scenario indicates future growth of 12% by 2035. Future potential changes to flooding and water quality are assessed under urbanisation and climate scenarios for the Thames region to provide comparative and cumulative analysis of how these drivers will affect existing and new urban areas within the Thames basin. Results show the relative and cumulative impacts that both urbanisation and climate change have on basin hydrology and water quality, and highlight the improvements in modelling accuracy when utilising high-resolution data. Discussion is made of results in relation to modelling, policy, mitigation options, and

    Full Text Available A traqueostomia apresenta uma série de vantagens em relação à entubação endotraqueal prolongada: conforto e maior possibilidade de comunicação para o paciente, diminuição da resistência respiratória, melhor controle de via aérea e facilidade de aspiração. No período de setembro de 1996 a dezembro de 1997 foram realizadas setenta traqueostomias à beira de leito na UTI, sob anestesia local, com tempo operatório médio de 30,5 minutos. A principal indicação foi ventilação mecânica prolongada, com uma média de 6,5 dias. Os pacientes foram acompanhados durante a internação por 1.494 dias. No terceiro dia de pós-operatório foi colhida cultura de secreção traqueal em 49 pacientes, predominando Pseudomonas aeruginosa em 40,8% dos casos. Houve 11 casos (15,7% de complicações maiores: uma fístula traqueoesofágica, uma fasciíte necrotizante, uma úlcera traqueal, duas infecções e seis sangramentos, que necessitaram reintervenção. Um óbito foi relacionado ao procedimento, devido à fasciíte necrotizante cervical. Tendo em vista a gravidade dos pacientes, a traqueostomia à beira de leito demonstrou ser um procedimento seguro e com baixo índice de complicações maiores.

    Full Text Available Landfill sites receive 92% of total annual solid waste produced by municipalities in the emirate of Abu Dhabi. In this study, candidate sites for an appropriate landfill location for the Abu Dhabi municipal area are determined by integrating geographic information systems (GIS and multi-criteria evaluation (MCE analysis. To identify appropriate landfill sites, eight input map layers including proximity to urban areas, proximity to wells and water table depth, geology and topography, proximity to touristic and archeological sites, distance from roads network, distance from drainage networks, and land slope are used in constraint mapping. A final map was generated which identified potential areas showing suitability for the location of the landfill site. Results revealed that 30% of the study area was identified as highly suitable, 25% as suitable, and 45% as unsuitable. The selection of the final landfill site, however, requires further field research.

    The intubation difficulties in obese patients are not a new problem. They may result from an accumulation of fat in the oral cavity and cheeks. A thick tongue is also a significant factor. The literature reports that some tests to determine the intubation difficulties in obese people may be unreliable. The observed predictors of difficult intubation were the thyromental and sternomental distance and the intubation difficulty scale: FRONT score.The aim of this study was to assess the degree of difficult intubation in obese patients by the parameters such as the thyromental and sternomental distance. The authors also tried to evaluate the frequency of the guidewire usage and the number of intubation attempts in obese patients in the research sample.The study included the group of 153 patients intubated in prehospital conditions. The research was conducted in 3 clinical centers receiving patients from prehospital care. Among the members of the research sample, obese patients with body mass index >35 were selected and evaluated for various predictors of intubation difficulties. Quantitative analysis of differences in the incidence of the variables was assessed using the chi-squared test for P < 0.05. Analyses were performed in STATISTICA.Complications such as postintubation hematomas were more frequent in obese patients of the research sample. The frequency of the guidewire usage observed in that group was also higher. As anticipated by the adopted predictors, most of the obese patients were classified as difficult to intubate.There is a correlation between the occurrence of injuries and the prevalence of obesity in the research sample and the same dependency has been demonstrated in the issue concerning the use of the guidewire. Although the majority of predictors indicated patients with intubation difficulties, many predictors could show falsely positive results. The greater amount of intubation attempts was observed in obese patients. Further studies devoted to

    Full Text Available This paper discusses the development and functioning of foster families, one of the priority interventions for children without parental care in Russia and abroad. The paper analyzes the current official statistics on the problem of child abandonment in Russia as a whole and in the Saratov and Belgorod regions of Russia in particular. The mechanism of social adaptation of children in foster care is based on the qualitative and quantitative methods (surveys and interviews of foster parents and foster children. The author identifies obstacles to the development of social institutions in the regions and the necessity of its active implementation in domestic social practices. The study found that foster care has been successful in areas where accepted legal basis allowed the recruiting, selecting candidates for adoptive parents, and foster care maintenance are carried out by social services. In addition, in order to reduce risk factors such as the secondary abandonment of foster children it is necessarily to increase assistance from the social guardianship bodies and professionals as well as building trusting parent-child relationships that use the democratic parenting style by foster parents.DOI: http://dx.doi.org/10.12731/2218-7405-2013-8-8

  4. Theoretical study of the adsorption of aromatic units on carbon allotropes including explicit (empirical) DFT dispersion corrections and implicitly dispersion-corrected functionals: the pyridine case.

    2015-01-01

    The suitability of implicitly dispersion-corrected functionals, namely the M06-2X, for the determination of interaction energies and electron polarization densities in adsorption studies of aromatic molecules on carbon allotropes surfaces is analysed by comparing the results with those obtained using explicit dispersion through Grimme's empirical corrections. Several models of increasing size for the graphene sheet together with one-dimensional curved carbon structures, (5,5), (6,6) and (7,7) armchair single-walled nanotubes, and two-dimensional curved carbon structures, C60 fullerene, have been considered as substrates in this work, whereas pyridine has been chosen as an example for the adsorbed aromatic molecule. Comparison with recent experimental estimations of the adsorption energy and calculations using periodic boundary conditions on a supercell of 72 carbon atoms indicates that a finite model containing ninety six carbon atoms (C96) approaches quite well the adsorption on a graphene sheet. Analysis of the interaction energy components reveals that the M06-2X functional accounts for most of the dispersion energy implicitly, followed far by wB97X and B3LYP, whereas B97 and BLYP do not differ too much from HF. It has been found that M06-2X corrects only the energy component associated to dispersion and leaves the rest, electrostatic, Pauli and induction "unaltered" with respect to the other DFT functionals investigated. Moreover, only the M06-2X functional reflects the effect of dispersion on the electron polarization density, whereas for the remaining functionals the polarization density does not differ too much from the HF density. This makes the former functional more suitable a priori for the calculation of electron density related properties in these adsorption complexes.

    Science.gov (United States)

    Bond, G G

    1993-01-01

    The need to notify individuals of a possible health risk from their past exposure to potentially hazardous agents frequently extends beyond workers to include community groups. The issues to consider in community notification are frequently similar to those that are important for worker notification but may include some that are unique. This case study traces the evolution of one company's strategy for communicating with the public about possible dioxin contamination associated with its operations. Early communications tended to emphasize the technical aspects of the issues in the fashion of scientists talking to other scientists. This was interpreted by some to be symptomatic of an arrogant and uncaring attitude. Beginning in the early 1980s, the company's management recognized the need to reach out to a variety of audiences on multiple levels, and shifted to a more comprehensive communications strategy. A similar shift is now occurring throughout the chemical manufacturing industry as top managers realize that, if they expect to continue to operate, they must become more accountable and responsive to the public.

    OBJECTIVES. To review the characteristics of a series of obstetric patients admitted to the intensive care unit in a regional hospital in 2006-2010, to compare them with those of a similar series reported from the same hospital in 1989-1995 and a series reported from another regional hospital in 1998-2007. DESIGN. Retrospective case series. SETTING. A regional hospital in Hong Kong. PATIENTS. Obstetric patients admitted to the Intensive Care Unit of Kwong Wah Hospital from 1 January 2006 to 31 December 2010. RESULTS. From 2006 to 2010, there were 67 such patients admitted to the intensive care unit (0.23% of total maternities and 2.34% of total intensive care unit admission), which was a higher incidence than reported in two other local studies. As in the latter studies, the majority were admitted postpartum (n=65, 97%), with postpartum haemorrhage (n=39, 58%) being the commonest cause followed by pre-eclampsia/eclampsia (n=17, 25%). In the current study, significantly more patients had had elective caesarean sections for placenta praevia but fewer had had a hysterectomy. The duration of intensive care unit stay was shorter (mean, 1.8 days) with fewer invasive procedures performed than in the two previous studies, but maternal and neonatal mortality was similar (3% and 6%, respectively). CONCLUSION. Postpartum haemorrhage and pregnancy-induced hypertension were still the most common reasons for intensive care unit admission. There was an increasing trend of intensive care unit admissions following elective caesarean section for placenta praevia and for early aggressive intervention of pre-eclampsia. Maternal mortality remained low but had not decreased. The intensive care unit admission rate by itself might not be a helpful indicator of obstetric performance.

    Case studies may have different research goals. One such goal is the testing of small-scale and middle-range theories. Theory testing refers to the critical examination, observation, and evaluation of the 'why' and 'how' of a specified phenomenon in a particular setting. In this paper, we focus...... on the strengths of theory-testing case studies. We specify research paths associated with theory testing in case studies and present a coherent argument for the logic of theoretical development and refinement using case studies. We emphasize different uses of rival explanations and their implications for research...... design. Finally, we discuss the epistemological logic, i.e., the value to larger research programmes, of such studies and, following Lakatos, conclude that the value of theory-testing case studies lies beyond naïve falsification and in their contribution to developing research programmes in a progressive...

    Systems to meet the on-demand learning needs of nurses in intensive care units are not well studied beyond the traditional classroom models. To study the feasibility and effect of implementing an online discussion forum for nurses in a busy neuroscience intensive care unit. A baseline survey was done to highlight the areas of educational need in the unit. Freeform-a password-protected, online discussion forum supported by the university-was used for the pilot project. Freeform has functions similar to Facebook, with "likes," "follow," discussion/comment spaces, and the capacity for uploading images and files. A page called "All things NeuroCritical Care" was created. All nurses working in the intensive care unit were automatically enrolled. Clinical vignettes relevant to neurocritical care were posted once a month with 1 to 2 lead questions. All participation was voluntary, and topics were chosen on the basis of the needs survey. At the end of each case, a recent review article on the topic was posted for secure download. Eight sentinel diagnoses have been presented as clinical vignettes, and 34 of 76 members formally follow the page. The mean number of discussion strings per case is 8.3 posts. The number of unique visitors to the page during active case discussions exceeds 100. A secure, online, problem-based learning discussion format is a feasible point-of-care learning opportunity that can help overcome some of the traditional barriers to ongoing nursing education needs in a busy intensive care unit. ©2016 American Association of Critical-Care Nurses.

Young scientists are often unaware of the rules in science and make mistakes because of their ignorance of the rules in that particular field of study. Then there are an increasing number of cases in the news of overt cases of misrepresentation in science. All are welcome to attend this discussion of case studies. A case study on topics such as: how to treat data properly, how our values in science affect our work, who gets authorship on scientific papers, who is first author on a paper, what you should do if you uncover misconduct or plagiarism in your university, and we will discuss the scientist's role in society. This will be a painless, non-confrontational small group, then large group discussion of each case

  16. Rabbit care unit for intravenous feeding and metabolic studies.

    Science.gov (United States)

    Haukipuro, K; Harju, E

    1986-01-01

    A simple rabbit care unit for peripheral intravenous feeding and metabolic studies was developed. The unit consists of six aluminum boxes with a common cover. Inverted T-shaped mobile supports hanging from the upper horizontal part of a frame hold the infusion lines. The side walls of the box prevent the rabbit from turning around, but other movements are possible. After initial training with 21 surgically treated animals, there was only one early anesthetic death among the subsequent 21 rabbits (4.8%). There was one late death (4.8%), and one animal was slightly, and two animals clearly, deteriorated. The ear vein cannula had to be changed in one-third of the animals not more than 3 days from the outset. Problems associated with the infusion systems or urinary bladder catheterization were minor. The results showed that it is practical to infuse rabbits via a peripheral intravenous route in a semi-restraining metabolic unit. The cases of late death and deterioration can be explained in part by the stress of experimental conditions with starvation and surgery, rather than by the effect of the metabolic unit alone. With previous experience in treating rabbits, we find the period required to learn this technique is short.

    Full Text Available This article is a qualitative case study describing the experience of Angélica an international graduate student from Latin America, who received her doctorate at the University of New Mexico in the United States. Her case demonstrated how administrators and faculty learn about the experience and struggles endured by international students, especially those who learned English a short time before admission to graduate studies. While a single case is understandably idiographic in nature and inevitably requires a larger sample, from the analysis of Angélica’s case and the analysis of the relevant literature common topics emerged persuading me to conclude that the issues that commonly impact the life of international students have to do with: 1 second language problems; 2 the quality of academic advisement received; 3 the availability of financial support; 4 the level of integration into their academic program; and 5 the level of cultural adjustment in their host country.

    In the course of the Ebola outbreak in West Africa that was witnessed since early 2014, the response mechanisms showed deficits in terms of timeliness, volume and adequacy. The authors were deployed in the Ebola campaign in the West African country Liberia, where by September 2014 the changing epidemiological pattern made reconsiderations of guidelines and adopted procedures necessary. A temporary facility set up as a conventional Ebola Treatment Unit in the Liberian capital Monrovia was re-dedicated into a Severe Infections Temporary Treatment Unit. This facility allowed for stratification based on the nosocomial risk of exposure to Ebola virus for a growing subgroup of admitted patients that in the end would turn out as Ebola negative cases. At the same time, adequate diagnostic measures and treatment for the non-Ebola conditions of these patients could be provided without compromising work safety of the employed staff. The key elements of the new unit comprised a Suspect Cases Area similar to that of conventional Ebola treatment units for newly arriving patients, an Unlikely Cases Area for patients with a first negative Ebola PCR result, and a Confirmed Negative Cases Area for patients in whom Ebola could be ruled out. The authors, comprising representatives of the Liberian Ministry of Health and Social Welfare, as well as infectious disease specialists from the German Ebola Task Force are presenting key features of the adapted concept, and are highlighting its relevance in raising acceptance for outbreak counter-measures within the population at stake.

  8. The epidemiology of pertussis and pertussis immunization in the United Kingdom and the United States: a comparative study.

    Science.gov (United States)

    Cherry, J D

    1984-02-01

    Pertussis is a common serious illness of childhood that can be controlled by immunization. It is a unique disease in that it is clinically manifested more often in females than in males. In the 20th century the mortality from pertussis has decreased steadily in both the United Kingdom and the United States. This decline in death rate was well underway prior to the introduction of pertussis vaccine but was accelerated after vaccine use became widespread. In recent years the case fatality rate in the United States has been considerably greater than that in the United Kingdom. One obvious reason for this difference is the difference in age-specific attack rates in the two nations. Available data also suggest that recent pertussis deaths in infants in England and Wales may frequently be reported as due to respiratory diseases other than pertussis. Although it is frequently suggested by some observers, there is no evidence that the incidence of pertussis was declining prior to the widespread use of vaccine. All available evidence indicates that pertussis vaccine use in both the United Kingdom and the United States was responsible for a drastic reduction in the magnitude of both endemic and epidemic pertussis. Decreased utilization of pertussis vaccine in England and Wales beginning in 1975 resulted in two major epidemics of pertussis in 1977-1979 and 1982-1983. Moderate local and systemic reactions commonly occur following pertussis immunization. These reactions appear to be less common and less severe in the United Kingdom than in the United States, but in contrast to recent studies in the United States, there are no recent quantitative studies in the United Kingdom. There are virtually no data available in the United States on the incidence of serious neurologic disease resulting from pertussis immunization. In contrast, the recently published findings of the NCES, a case-control study of national scope, have allowed attributable risk estimates of serious neurologic

  10. Functional redundancy and the process of professionalization: the case of registered nurses in the United States.

    Science.gov (United States)

    Levi, M

    1980-01-01

    Registered nurses have been attempting to achieve professional status for nearly a century. Historical investigation of their efforts in the United States and a case study of the 1976 Seattle Nurses' strike indicate major obstacles to the professionalizing project. The most important of these are the inability of the nurses to control the labor supply, and their failure to define or monopolize a distinct set of tasks. One result is functional redundancy: there is no job nurses perform that is not also performed by some other occupation.

  18. Guidelines for Conducting Positivist Case Study Research in Information Systems

    Directory of Open Access Journals (Sweden)

    Graeme Shanks

    2002-11-01

    Full Text Available The case study research approach is widely used in a number of different ways within the information systems community. This paper focuses on positivist, deductive case study research in information systems. It provides clear definitions of important concepts in positivist case study research and illustrates these with an example research study. A critical analysis of the conduct and outcomes of two recently published positivist case studies is reported. One is a multiple case study that validated concepts in a framework for viewpoint development in requirements definition. The other is a single case study that examined the role of social enablers in enterprise resource planning systems implementation. A number of guidelines for successfully undertaking positivist case study research are identified including developing a clear understanding of key concepts and assumptions within the positivist paradigm; providing clear and unambiguous definitions of the units and interactions when using any theory; carefully defining the boundary of the theory used in the case study; using hypotheses rather than propositions in the empirical testing of theory; using fuzzy or probabilistic propositions in recognising that reality can never be perfectly known; selecting case studies carefully, particularly single case studies; and recognising that generalisation from positivist, single case studies is inherently different from generalisation from single experiments. When properly undertaken, positivist, deductive case study research is a valuable research approach for information systems researchers, particularly when used within pluralist research programs that use a number of different research approaches from different paradigms.

    Currently in the United States, the heavy majority of plug-in electric vehicle (PEV) sales have been in highly conducive, selected, metropolitan areas; opposed to more broad distribution across the country. The U.S. Department of Energy’s EV Everywhere Grand Challenge is looking carefully at the barriers and opportunities that exist to enable small and midsize communities to partake in the PEV market and benefit from the economic and environmental advantages of PEVs. In order to gain insight into these challenges and barriers, DOE selected a success story (i.e., Drive Electric Vermont) as the subject of this case study, as the state of Vermont is tied with Detroit, Michigan in having the highest percentage of 2014 (most recent complete data) PEV registrations for cold weather U.S. cities and has seen more than a sixfold increase in charging stations over the last three years. The overall objective of this case study was to use the lessons learned from Drive Electric Vermont to determine what activities are most effective at encouraging acquisitions of PEVs and deployment of charging infrastructure in small to midsize communities, prioritizing and sequencing their implementation, identifying robust means for extrapolation, and applying this understanding to other small to midsize communities across the nation. The Drive Electric Vermont Program was formed in 2012 with a goal of increasing the use of electrified transportation in Vermont through policy development, education and outreach, and infrastructure development. The Drive Electric Vermont Program can be broadly broken into four components: (1) strategic planning/leadership, (2) stakeholder/partnership development, (3) education and outreach, and (4) incentives. The early phases of the program focused heavily on strategic planning, and stakeholder and partnership development, followed by a transition to education and outreach activities, charging infrastructure development, and grant and incentive programs

    2015-04-01

    Full Text Available This article describes an action research project conducted at Los Alamos National Laboratory (LANL to resolve a problem with the ability of licensed and/or certified engineers to obtain the ethics-related professional development units or hours (PDUs or PDHs needed to maintain their credentials. Because of the recurring requirement and the static nature of the information, an initial, in-depth training followed by annually updated refresher training was proposed. A case model approach, with online delivery, was selected as the optimal pedagogical model for the refresher training. In the first two years, the only data that was collected was throughput and information retention. Response rates indicated that the approach was effective in helping licensed professional engineers obtain the needed PDUs. The rates of correct responses suggested that knowledge transfer regarding ethical reasoning had occurred in the initial training and had been retained in the refresher. In FY13, after completing the refresher, learners received a survey asking their opinion of the effectiveness and utility of the course, as well as their impressions of the case study format vs. the typical presentation format. Results indicate that the courses have been favorably received and that the case study method supports most of the pedagogical needs of adult learners as well as, if not better than, presentation-based instruction. Future plans for improvement are focused on identifying and evaluating methods for enriching online delivery of the engineering ethics cases.

    2001-01-01

    The Global Hydrology and Climate Center and NASA's Marshall Space Flight Center conducted a fact-finding case study for the Data Management Working Group (DMWG), now referred to as the Data and Information Working Group (DIWG), of the U.S. Global Change Research Program (USGCRP) to determine the feasibility of an interagency National Environmental Change Information System (NECIS). In order to better understand the data and information needs of policy and decision makers at the national, state, and local level, the DIWG asked the case study team to choose a regional water resources issue in the southeastern United States that had an impact on a diverse group of stakeholders. The southeastern United States was also of interest because the region experiences interannual climatic variations and impacts due to El Nino and La Nina. Jointly, with input from the DIWG, a focus on future water resources planning in the Apalachicola-Chattahoochee-Flint (ACF) River basins of Alabama, Georgia, and Florida was selected. A tristate compact and water allocation formula is currently being negotiated between the states and U.S. Army Corps of Engineers (COE) that will affect the availability of water among competing uses within the ACF River basin. All major reservoirs on the ACF are federally owned and operated by the U.S. Army COE. A similar two-state negotiation is ongoing that addresses the water allocations in the adjacent Alabama-Coosa-Tallapoosa (ACT) River basin, which extends from northwest Georgia to Mobile Bay. The ACF and ACT basins are the subject of a comprehensive river basin study involving many stakeholders. The key objectives of this case study were to identify specific data and information needs of key stakeholders in the ACF region, determine what capabilities are needed to provide the most practical response to these user requests, and to identify any limitations in the use of federal data and information. The NECIS case study followed the terms of reference

  5. Growth units and nucleation: The case of calcium phosphates

    Science.gov (United States)

    Boistelle, Roland; Lopez-Valero, Isabel

    1990-05-01

    Calcium phosphates are precipitated at 37°C from solutions the pH of which ranges from 5.0 to 11.0. Despite the fact that the supersaturations of hydroxyapatite HAP, octocalcium phosphate OCP and brushite B are often in the order HAP≫OCP≫B, brushite nucleates more easily than OCP and HAP at low pH, while OCP nucleates more easily than HAP at mean to high pH. These facts cannot be explained, as usually, by the only differences in the surface free energies of the three solid phases. On the other hand, they may be explained by assuming that the values of the kinetic coefficients change as a function of the concentration in the proper growth units which have to integrate in the nuclei of either phase. In the model we propose, the kinetic coefficients of OCP and HAP are smaller than that of B by 10 and 18 orders of magnitude at pH=6.5, differences which reduce to 3 orders of magnitude at pH=10.0. Accordingly, nucleation of OCP and HAP is favoured with increasing pH.

    Objective. The aim of this study was to determine the protein-calorie nutritional status of elderly hospitalized patients admitted to the hepato-gastroenterology, cardiology and internal medicine departments of the Lomé Campus University Hospital and identify the endogenous and mixed undernutrition to provide patients with better nutrition and assistance. Methodology. This cross-sectional study conducted between April 1 and July 31, 2009, included 33 hospitalized case patients aged at least 55 years and 30 age-matched outpatient control subjects. Patients were evaluated according to body mass index (BMI), the Mini Nutritional Assessment (MNA), and their serum albumin, serum prealbumin and orosomucoid levels. Results. Among the hospitalized case patients, 37% had protein-calorie undernutrition (low serum albumin), and 73% were at risk of this undernutrition (low serum prealbumin). Five patients (16%) were endogenously undernourished and 17 (57%) exogenously undernourished. Six to 13% of the oupatient controls were undernourished and 33% at risk of undernutrition according to the MNA scale. A significant difference existed between the mean albumin values of case patients and controls (38 ± 9 g/L vs 46 ± 7 g/L, p = 0.002). Conclusion. Our results confirm that the elderly inpatients were regularly malnourished. Knowledge of their nutritional profile has allowed us to launch an improved nutritional assistance program and to supervise it properly.

    Full Text Available This is a report of a case study on 234 patients with impetigo who referred to Razi Dermatology Hospital from April to November, 1989. Treatment was started immediately after obtaining direct smear and performing culture and antibiotic sensitivity test. The most common organism responsible for impetigo was the coagulase-positive staphylococcus (71%. In 13.7% of the cases, the coagulase-negative staphylococcus was grown on culture media, but none of the cultures showed streptococcus as the main organism. Treatment was started with oral penicillin V, oral erythromycin, benzathine penicillin G injection, oral cephalexin, and topical fuccidin. Clinical and bacteriological evaluation after 3-7 days showed that it is preferable to use oral cephalexin instead of other protocols such as oral erythromycin, which has previously been the drug of choice for impetigo. In addition, topical fuccidin with a 75% curative rate was the first drug for treatment, with the same effect as the oral cephalexin

    Previous studies have failed to identify mutations in the Wilson's disease gene ATP7B in a significant number of clinically diagnosed cases. This has led to concerns about genetic heterogeneity for this condition but also suggested the presence of unusual mutational mechanisms. We now present our findings in 181 patients from the United Kingdom with clinically and biochemically confirmed Wilson's disease. A total of 116 different ATP7B mutations were detected, 32 of which are novel. The overall mutation detection frequency was 98%. The likelihood of mutations in genes other than ATP7B causing a Wilson's disease phenotype is therefore very low. We report the first cases with Wilson's disease due to segmental uniparental isodisomy as well as three patients with three ATP7B mutations and three families with Wilson's disease in two consecutive generations. We determined the genetic prevalence of Wilson's disease in the United Kingdom by sequencing the entire coding region and adjacent splice sites of ATP7B in 1000 control subjects. The frequency of all single nucleotide variants with in silico evidence of pathogenicity (Class 1 variant) was 0.056 or 0.040 if only those single nucleotide variants that had previously been reported as mutations in patients with Wilson's disease were included in the analysis (Class 2 variant). The frequency of heterozygote, putative or definite disease-associated ATP7B mutations was therefore considerably higher than the previously reported occurrence of 1:90 (or 0.011) for heterozygote ATP7B mutation carriers in the general population (P Wilson's disease of 1:30 000 (P = 0.00093). Our study provides strong evidence for monogenic inheritance of Wilson's disease. It also has major implications for ATP7B analysis in clinical practice, namely the need to consider unusual genetic mechanisms such as uniparental disomy or the possible presence of three ATP7B mutations. The marked discrepancy between the genetic prevalence and the number of

    Acute limb ischemia is a complication of severe peripheral arterial disease that can be a threatening limb as well as life. Multiple procedures exist today to help revascularize extremities; however, even with the latest technologies, surgical amputation of the limb may still be necessary. Cryoamputation, or physiologic amputation, is a method used to treat patients who are hemodynamically unstable for the operating room and who are in need of urgent amputation owing to arterial ischemia. This procedure is used in the rare instance where not only a persons' limb is threatened, but also their life. This is a case study regarding one patient who presented to the hospital with limb-threatening ischemia who became hemodynamically unstable owing to the rhabdomyolysis associated with the ischemia of his lower extremity. Cryoamputation was used to stabilize the patient and prevent further deterioration, so that he could safely undergo surgical amputation of the limb without an increase in mortality risk. Cryoamputation must be followed by formal surgical amputation when the patient is hemodynamically stabilized. It is not a limb salvaging, procedure but it is a life-saving procedure. This case study demonstrates the usefulness of the procedure and discusses the technique used for cryoamputation.

    Obsessional slowness is a rare psychiatric disorder with few treatment options and limited research to date. Some suggest that targeted behavioural interventions may reduce the time taken for functional daily activities. To examine whether a behavioural intervention would reduce the amount of time taken for an adolescent with obsessional slowness to walk to class. A single-subject A-B-A withdrawal design was incorporated into this case study. The treatment involved one-to-one pacing and prompting during the subject's walk to gym class. Walking times to gym class were measured during a baseline phase, during a one-month treatment phase, and during a post-treatment follow-up phase. The subject's walking times decreased during the treatment phase. Post-treatment walking times suggested a carry-over effect. This study adds to the sparse evidence on treatments for obsessional slowness and suggests occupation-based treatment options.

    Because the Mexican government has encouraged investment in Mexico by increasing the percentage of ownership of a Mexican business that a US company can hold, joint ventures are more attractive now than they had been in the past. This study provides preliminary information for US renewable energy companies who are interested in forming a joint venture with a Mexican company. This report is not intended to be a complete reference but does identifies a number of important factors that should be observed when forming a Mexican joint venture: (1)Successful joint ventures achieve the goals of each partner. (2)It is essential that all parties agree to the allocation of responsibilities. (3)Put everything in writing. (4)Research in depth the country or countries in which you are considering doing business.

    Awareness with recall after general anesthesia is an infrequent, but well described, phenomenon that may result in posttraumatic stress disorder. There are no recent data on the incidence of this complication in the United States. We, therefore, undertook a prospective study to determine the incidence of awareness with recall during general anesthesia in the United States. This is a prospective, nonrandomized descriptive cohort study that was conducted at seven academic medical centers in the United States. Patients scheduled for surgery under general anesthesia were interviewed in the postoperative recovery room and at least a week after anesthesia and surgery by using a structured interview. Data from 19,575 patients are presented. A total of 25 awareness cases were identified (0.13% incidence). These occurred at a rate of 1-2 cases per 1000 patients at each site. Awareness was associated with increased ASA physical status (odds ratio, 2.41; 95% confidence interval, 1.04-5.60 for ASA status III-V compared with ASA status I-II). Age and sex did not influence the incidence of awareness. There were 46 additional cases (0.24%) of possible awareness and 1183 cases (6.04%) of possible intraoperative dreaming. The incidence of awareness during general anesthesia with recall in the United States is comparable to that described in other countries. Assuming that approximately 20 million anesthetics are administered in the United States annually, we can expect approximately 26,000 cases to occur each year.

    Our objective was to describe racial and ethnic differences of amyotrophic lateral sclerosis (ALS) in distinct geographic locations around the United States (U.S.). ALS cases for the period 2009-2011 were identified using active case surveillance in three states and eight metropolitan areas. Of the 5883 unique ALS cases identified, 74.8% were white, 9.3% were African-American/black, 3.6% were Asian, 12.0% were an unknown race, and 0.3% were marked as some other race. For ethnicity, 77.5% were defined as non-Hispanic, 10.8% Hispanic, and 11.7% were of unknown ethnicity. The overall crude average annual incidence rate was 1.52 per 100,000 person-years and the rate differed by race and ethnicity. The overall age-adjusted average annual incidence rate was 1.44 per 100,000 person-years and the age-adjusted average incidence rates also differed by race and ethnicity. Racial differences were also found in payer type, time from symptom onset to diagnosis, reported El Escorial criteria, and age at diagnosis. In conclusion, calculated incidence rates demonstrate that ALS occurs less frequently in African-American/blacks and Asians compared to whites, and less frequently in Hispanics compared to non-Hispanics in the U.S. A more precise understanding of racial and ethnic variations in ALS may help to reveal candidates for further studies of disease etiology and disease progression.

    Full Text Available Country image is an issue that is becoming more relevant in the last few years due to competition generated among countries to attract tourists and increase their exports in the wake of globalization. Nowadays, countries are more concerned about country image being projected and, therefore, the favourable or unfavourable perception that consumers have of the country. This research is an exploratory study to determine the components of the United States of America country image, from the perspective of consumers of Peru and France. The United States was chosen for purposes of this study because it is the country that provides the greatest flow of tourists to Peru and is the main destination market for exports; while in the case of France it is the opposite: it has a low rate of tourists and trade. This allows comparing the results of two samples: one with a high level of familiarity (Peru and one with a low level of familiarity (France. The same questionnaire was used for both markets under the same conditions, and the same variables and indicators were measured.

At present, many manufacturing companies are facing problems such as high quality rejection, high inventories, high lead time, high costs of production, and inability to cope with customer orders. By implementing and practicing the lean production system many problems can be solved without employing high-tech and high-touch approaches but by involving people on the shop floor in Kaizen activities. Kaizen is one of the powerful tools of lean manufacturing. Kaizen refers to continuous improvement in performance, cost and quality. Kaizen ensures that manufacturing processes become leaner and fitter, but eliminate waste (problem where value is added. The main objective of this paper is to provide a background on kaizen, present an overview of kaizen concepts that are used to transform a company into a high performing lean enterprise. A case study of implementation of Kaizen‟s has been discussed.

    2011-06-01

    Case studies can be useful in assessing and learning lessons from emergency situations. In this paper, different uses for disaster case studies, are explored with identification of potential pitfalls that should be avoided. In addition, ways to improve the rigor and significance of case studies are suggested. Case studies can be used as examples or as a research tool. If conducted properly, they can provide robust and compelling results. It is argued that sharing a common guide to conducting and writing case studies among all disaster risk reduction professionals could improve the quality of case study reports and thereby strengthen their value in advancing the prevention, preparedness, and management of disasters and emergencies.

    2011-01-01

    Pain is a widespread issue in the United States. Nine of 10 Americans regularly suffer from pain, and nearly every person will experience low back pain at one point in their lives. Undertreated or unrelieved pain costs more than $60 billion a year from decreased productivity, lost income, and medical expenses. The ability to diagnose and provide appropriate medical treatment is imperative. This case study examines a 23-year-old Active Duty woman who is preparing to be involuntarily released from military duty for an easily correctable medical condition. She has complained of chronic low back pain that radiates into her hip and down her leg since experiencing a work-related injury. She has been seen by numerous providers for the previous 11 months before being referred to the chronic pain clinic. Upon the first appointment to the chronic pain clinic, she has been diagnosed with sacroiliac joint dysfunction. This case study will demonstrate the importance of a quality lower back pain assessment.

    Full Text Available It is widely accepted that universities can play critical roles in promoting sustainability. In the United States and China, many universities have initiated sustainability programs. Employing Indiana University, Bloomington, the U.S. (IUB and Tsinghua University, Beijing, China (Tsinghua as two cases, we examine the conceptualization and implementation of university sustainability programs through a comparison of their respective definitions, goals, organizational dynamics, and strategies. We find that IUB’s sustainability scheme is more detailed and specific, while Tsinghua’s is more general; this is principally attributable to differences in national and local contexts. Furthermore, IUB values the environmental, economic, and social aspects of university sustainability equally, while Tsinghua focuses more on the environmental aspect. In addition, IUB has a more loosely-structured and more inclusive sustainability organizational dynamic while Tsinghua has a more hierarchical one. This comparative study helps us to understand how these two research universities understand and implement sustainability within the respective cultural, political, and institutional contexts of the United States and China.

    2003-05-01

    The twenty-seventh documented case of human Mesocestoides infection, which corresponds to the seventh documented case in the United States, is reported. The case had its origin in Alexandria, Louisiana in the summer of 1998. The patient was a 19-month-old boy. The strobila consisted of 35 proglottids that included mature as well as gravid segments containing a ventral genital pore and a parauterine organ. After a detailed microscopic examination, the tapeworm was identified as belonging to the genus Mesocestoides. Mesocestoides variabilis is the probable species responsible for the infection, since the six cases previously reported in the United States were identified as this species. After the treatment with a single dose of praziquantel (10 mg/kg), the tapeworm segments were no longer detectable in the child's feces. A food-borne origin of this infection derived from culinary customs of the Acadian and Creole communities in Louisiana is proposed.

    Full Text Available Aim: The aim of this study was to evaluate the suicide and intoxication cases between April 2011 and April 2013. Methods: We retrospectively analyzed hospital records of patients who were admitted to our intensive care unit due to suicide and intoxication. The age, sex, intoxication causes, laboratory analyses, treatment refusal rates, and the prognosis were evaluated. Results: A total of 308 patients (105 males, 203 females were admitted to the intensive care unit. The mean age of the patients was 27.45±10.26 years (males: 28.70±9.86 years, females: 26.80±10.43 years. There were only 4 patients over 65 years of age. 275 patients had drug intoxication (antidepressant drug, pain killer, antibiotic, etc. and 33 patients had other causes of intoxication. When analyzing the prognosis; a total of 234 patients were discharged after initial treatment and 57 patients were discharged due to treatment refusal. 15 patients were referred for inpatient psychiatric treatment, 1 patient to the Alcohol and Drug Addiction Treatment Center (AMATEM and 1 patient was referred to İstanbul University Medical Faculty due to acute hepatic failure. Conclusion: The patients admitted to our intensive care unit due to suicide and intoxications were mainly females (65.9% and individuals of young age (median age: 27.45 years. Female patients had used antidepressants for suicide attempts and males had used antiflu-acetaminophen combinations. No mortality was observed. (The Me­di­cal Bul­le­tin of Ha­se­ki 2014; 52:153-7

  4. A case study for effects of operational taxonomic units from intracellular endoparasites and ciliates on the eukaryotic phylogeny: phylogenetic position of the haptophyta in analyses of multiple slowly evolving genes.

    Directory of Open Access Journals (Sweden)

    Hisayoshi Nozaki

    Full Text Available Recent multigene phylogenetic analyses have contributed much to our understanding of eukaryotic phylogeny. However, the phylogenetic positions of various lineages within the eukaryotes have remained unresolved or in conflict between different phylogenetic studies. These phylogenetic ambiguities might have resulted from mixtures or integration from various factors including limited taxon sampling, missing data in the alignment, saturations of rapidly evolving genes, mixed analyses of short- and long-branched operational taxonomic units (OTUs, intracellular endoparasite and ciliate OTUs with unusual substitution etc. In order to evaluate the effects from intracellular endoparasite and ciliate OTUs co-analyzed on the eukaryotic phylogeny and simplify the results, we here used two different sets of data matrices of multiple slowly evolving genes with small amounts of missing data and examined the phylogenetic position of the secondary photosynthetic chromalveolates Haptophyta, one of the most abundant groups of oceanic phytoplankton and significant primary producers. In both sets, a robust sister relationship between Haptophyta and SAR (stramenopiles, alveolates, rhizarians, or SA [stramenopiles and alveolates] was resolved when intracellular endoparasite/ciliate OTUs were excluded, but not in their presence. Based on comparisons of character optimizations on a fixed tree (with a clade composed of haptophytes and SAR or SA, disruption of the monophyly between haptophytes and SAR (or SA in the presence of intracellular endoparasite/ciliate OTUs can be considered to be a result of multiple evolutionary reversals of character positions that supported the synapomorphy of the haptophyte and SAR (or SA clade in the absence of intracellular endoparasite/ciliate OTUs.

    2014-12-01

    Concentrated Photovoltaics (CPV), once a niche technology, has now reached the maturity and reliability for large scale power generation. Especially in regions where temperatures are very high, the use of high efficiency triple junction solar cells with concentrating optics allows stable energy yield. Thus CPV can be seen as complementary and not in concurrence with silicon photovoltaics. The state of the art, the advantages and limitations of this technology will be shown. Among the main advantages of CPV is the possibility of a much higher energy supply, when compared to silicon photovoltaics, both comparing CPV and silicon with same area or the same installed power. The use of recycled and recyclable materials allows a more environmentally friendly production. The possibility to couple CPV with desalination facilities, energy storage will be analysed. As an example a case study of a CPV installation in Northern Italy is discussed. Here the use of mature technologies, derived from automotive and lighting sectors resulted in a simple and efficient module.

As an example a case study of a CPV installation in Northern Italy is discussed. Here the use of mature technologies, derived from automotive and lighting sectors resulted in a simple and efficient module.

  18. Women’s experience of transfer from midwifery unit to hospital obstetric unit during labour: a qualitative interview study

    Directory of Open Access Journals (Sweden)

    Rowe Rachel E

    2012-11-01

    Full Text Available Abstract Background Midwifery units offer care to women with straightforward pregnancies, but unforeseen complications can arise during labour or soon after birth, necessitating transfer to a hospital obstetric unit. In England, 21% of women planning birth in freestanding midwifery units are transferred; in alongside units, the transfer rate is 26%. There is little high quality contemporary evidence on women’s experience of transfer. Methods We carried out a qualitative interview study, using semi-structured interviews, with women who had been transferred from a midwifery unit (freestanding or alongside in England up to 12 months prior to interview. Maximum variation sampling was used. Interviews with 30 women took place between March 2009 and March 2010. Thematic analysis using constant comparison and exploration of deviant cases was carried out. Results Most women hoped for or expected a natural birth and did not expect to be transferred. Transfer was disappointing for many; sensitive and supportive care and preparation for the need for transfer helped women adjust to their changing circumstances. A small number of women, often in the context of prolonged labour, described transfer as a relief. For women transferred from freestanding units, the ambulance journey was a “limbo” period. Women wondered, worried or were fearful about what was to come and could be passive participants who felt like they were being “transported” rather than cared for. For many this was a direct contrast with the care they experienced in the midwifery unit. After transfer, most women appreciated the opportunity to talk about their experience to make sense of what happened and help them plan for future pregnancies, but did not necessarily seek this out if it was not offered. Conclusions Transfer affects a significant minority of women planning birth in midwifery units and is therefore a concern for women and midwives. Transfer is not expected by women, but

    Circiumaru, B; Baldock, G; Cohen, J

    1999-07-01

    To determine the epidemiology of fever on the intensive care unit (ICU). Prospective, observational study. Nine-bed general ICU in a 500-bed tertiary care inner city institution. 100 consecutive admissions of 93 patients over a 4-month period between July and October 1996. All patients were seen and examined by one investigator within 24 h of ICU admission. Patients were followed up on a daily basis throughout their ICU stay, and all clinical and laboratory data were recorded during the admission. Fever (core temperature > or = 38.4 degrees C) was present in 70% of admissions, and it was caused by infective and non-infective processes in approximately equal number. Most fevers occurred early in the course of the admission, within the first 1-2 days, and most lasted less than 5 days. The median Acute Physiology and Chronic Health Evaluation (APACHE) II score was 15 (+/- 0.6). The 70 episodes associated with fever at any time were associated with a significantly higher APACHE II score on admission than the afebrile episodes (15.8 +/- 6.1 vs 12.1 +/- 6.7, p = 0.04). The most common cause of non-infective fever was in the group designated post-operative fever (n = 34). All the patients in the post-operative fever group were febrile on day 0 or day 1; their mean admission APACHE score was 12.4 (+/- 4.4) compared to 15.9 (+/- 7.1) for the remaining patients (p = 0.01). Fever alone was not associated with a higher mortality: 26/70 (37%) of febrile patients died, compared to 8/30 (27%) of afebrile patients, (chi 2 = 1.23, p = 0.38). Prolonged fever (> 5 days) occurred in 16 patients. In 13 cases, fever was due to infection, and in the remaining 3 both infective and non-infective processes occurred concurrently. The mortality in the group with prolonged fever was 62.5% (10/16) compared to 29.6% (16/54) in patients with fever of less than 5 days' duration, a highly significant difference (p Fever is a common event on the intensive care unit.

  2. Five misunderstandings about case study research

    DEFF Research Database (Denmark)

    Flyvbjerg, Bent

    2004-01-01

    This article examines five common misunderstandings about case-study research: (1) Theoretical knowledge is more valuable than practical knowledge; (2) One cannot generalize from a single case, therefore the single case study cannot contribute to scientific development; (3) The case study is most...... useful for generating hypotheses, while other methods aremore suitable for hypotheses testing and theory building; (4) The case study contains a bias toward verification; and (5) It is often difficult to summarize specific case studies. The article explains and corrects these misunderstandings one by one...... and concludes with the Kuhnian insight that a scientific discipline without a large number of thoroughly executed case studies is a discipline without systematic production of exemplars, and that a discipline without exemplars is an ineffective one. Social science may be strengthened by the execution of more...

    Full Text Available Systems analysis students seldom experience the practical difficulties of the initial investigation into a client’s requirements. They get little chance to practice the skills they need to investigate complex and confused problem situations, or to appreciate the wider organizational issues that can impact on a situation. This teaching case is designed to give students the opportunity to practice and apply investigation skills and to challenge them to consider the wider work environment when considering possible solutions to a problem situation. The case is conducted as a role-play, with students acting as systems analysts and teaching staff role-playing the clients. The students develop a report analyzing the client’s situation based on the issues that arise during the interviews. Feed-back sessions focus on discussing how well the students applied various interviewing strategies previously covered in lectures, and on the wider organizational problems that could impact proposed information system solutions.

    Lewis, Geraint; Wright, Lorraine; Vaithianathan, Rhema

    2012-10-01

    Virtual wards are a model for delivering multidisciplinary case management to people who are at high predicted risk of unplanned acute care hospitalization. First introduced in Croydon, England, in 2006, this concept has since been adopted and adapted by health care organizations in other parts of the United Kingdom and internationally. In this article, the authors review the model of virtual wards as originally described-with its twin pillars of (1) using a predictive model to identify people who are at high risk of future emergency hospitalization, and (2) offering these individuals a period of intensive, multidisciplinary preventive care at home using the systems, staffing, and daily routines of a hospital ward. The authors then describe how virtual wards have been modified and implemented in 6 sites in the United Kingdom, United States, and Canada where they are subject to formal evaluation. Like hospital wards, virtual wards vary in terms of patient selection, ward configuration, staff composition, and ward processes. Policy makers and researchers should be aware of these differences when considering the evaluation results of studies investigating the cost-effectiveness of virtual wards.

    Full Text Available SUMMARY Invasive pulmonary aspergillosis (IPA is an infection rarely seen in intensive care units (ICU. We aimed to discuss the case of IPA found in a patient followed up in our ICU due to chronic obstructive pulmonary disease (COPD. A 58-year old patient diagnosed with COPD has been admitted to our ICU due to respiratory failure. There were not any other diseases except from COPD. In his radiological imaging there were diffuse bilateral infiltrates in the chest X-ray and diffuse infiltration in the thorax tomography. Aspergillus spp was isolated in the bronchoalveolar lavage sample from patient and caspofungin was added to the treatment. On the 12th day of the treatment, it was observed that the results of the control radiological imaging became normal and there was no isolation in the control cultures. In recent years, fungal infections have been determined at an increasing rate in the patients who are not immunosuppressed and hospitalized in ICU. In the IPA cases, it has been shown that such underlying causes as diabetes, malnutrition, use of steroid, uremia, cirrhosis and COPD may create risk. Our patient did not have other disease except from COPD and there was a story of prolonged using of steroid. Steroids are quite frequently used in the ICUs. In the patients with chronic pulmonary diseases, even if it is low dose and short-term, the treatment of steroid is accepted as a risk factor in terms of IPA. Since signs and symptoms are atypical in this group of patients, it is rather difficult to diagnose IPA in the short term. The isolation of aspergillus in our patient’s tracheal aspirate taken earlier enabled us to start the treatment early. Although there are not comprehensive studies, it should be kept in mind that İPA may develop in the patients who is using long-term steroid, is admitted to the ICUs due to COPD exacerbations without any other disease.

    Zamorano, Lucia J.; Dujovny, Manuel

    1991-05-01

    A unit is presented that provides the neurosurgeon with CT, MRI, x-ray, DA, and DSA compatible headholder and multimodality image localization as well as freedom of choice for surgical approach on patient's intraoperative positioning. The unit consists of a carbon fiber ring-shaped headholder which allows free selection for location of three or four fixation pins, avoiding interference with the flap sites or craniotomy. The base ring is mounted intraoperatively on a special adapter that allows any patient positioning including supine, lateral, prone, 3/4 prone, sitting, etc. Surgical draping can be performed given a completely sterile field. An arc/quadrant localizing device can be mounted on any four alternative positions according to the neurosurgeon's preference. A PC compatible software gives the setting for any possible mounting. Intraoperative the localizing unit can be used in a 'fixed' permanent setting or as a 'non-fixed' system to provide intraoperative three-dimensional orientation. Different are adapted instruments which give the unit further capabilities, especially 'bayonet' type brain retractors (cylinders and speculum) that allows the neurosurgeon to keep the surgical corridor unobstructed from the arc. As an alternative, in the 'non-fixed' setting, self-retaining arms are fixed to the base ring and brain retractors and conventional microsurgical technique can be used without any mechanical obstruction. This article presents the unit details, methodology and the clinical experience in 103 consecutive cases of 'open stereotaxis' for resection or internal decompression of deep seated or near eloquent area lesions.

    Full Text Available Abstract Background In view of the close relationship of Portugal with African countries, particularly former Portuguese colonies, the diagnosis of malaria is not a rare thing. When a traveller returns ill from endemic areas, malaria should be the number one suspect. World Health Organization treatment guidelines recommend that adults with severe malaria should be admitted to an intensive care unit (ICU. Methods Severe cases of malaria in patients admitted to an ICU were reviewed retrospectively (1990-2011 and identification of variables associated with in-ICU mortality performed. Malaria prediction score (MPS, malaria score for adults (MSA, simplified acute physiology score (SAPSII and a score based on WHO's malaria severe criteria were applied. Statistical analysis was performed using StataV12.

    Full Text Available The aim of the present study was raising the innovativeness of sand reclamation units through application of a new material - austempered ductile iron (ADI - for elements exposed to abrasion wear and impacts. Methods used for casting of ADI blades for disk-type reclamation units were described along with the results of tests and measurements of the obtained hardness, strength and microstructure. The ready ADI castings of blades were next subjected to performance tests to compare them with the conventionally made cast steel blades operating under industrial conditions. The obtained results of the tests confirmed high properties and numerous benefits offered by ADI respetive of cast steel used as a material for elements of sand reclamation units.

    Full Text Available Abstract Background Since 1953, through the cooperation of state and local health departments, the U.S. Centers for Disease Control and Prevention (CDC has collected information on incident cases of tuberculosis (TB disease in the United States. In 2009, TB case rates declined -11.4%, compared to an average annual -3.8% decline since 2000. The unexpectedly large decline raised concerns that TB cases may have gone unreported. To address the unexpected decline, we examined trends from multiple sources on TB treatment initiation, medication sales, and laboratory and genotyping data on culture-positive TB. Methods We analyzed 142,174 incident TB cases reported to the U. S. National Tuberculosis Surveillance System (NTSS during January 1, 2000-December 31, 2009; TB control program data from 59 public health reporting areas; self-reported data from 50 CDC-funded public health laboratories; monthly electronic prescription claims for new TB therapy prescriptions; and complete genotyping results available for NTSS cases. Accounting for prior trends using regression and time-series analyses, we calculated the deviation between observed and expected TB cases in 2009 according to patient and clinical characteristics, and assessed at what point in time the deviation occurred. Results The overall deviation in TB cases in 2009 was -7.9%, with -994 fewer cases reported than expected (P Conclusions Our assessments show that the decline in reported TB was not an artifact of changes in surveillance methods; rather, similar declines were found through multiple data sources. While the steady decline of TB cases before 2009 suggests ongoing improvement in TB control, we were not able to identify any substantial change in TB control activities or TB transmission that would account for the abrupt decline in 2009. It is possible that other multiple causes coincident with economic recession in the United States, including decreased immigration and delayed access to

    Assessment of caprock sealing behavior for secure CO2 storage is a multiscale endeavor. Sealing behavior arises from the nano-scale capillarity of pore throats, but sealing lithologies alone do not guarantee an effective seal since bypass systems, such as connected, conductive fractures can compromise the integrity of the seal. We apply pore-to-formation-scale data to characterize the multiscale caprock sealing behavior of the Morrow shale and Thirteen Finger Limestone. This work is part of the Southwest Regional Partnership on Carbon Sequestration's Phase III project at the Farnsworth Unit, Texas. The caprock formations overlie the Morrow sandstone, the target for enhanced oil recovery and injection of over one million metric tons of anthropogenically-sourced CO2. Methods include: focused ion beam-scanning electron microscopy; laser scanning confocal microscopy; electron and optical petrography; multi-stress path mechanical testing and constitutive modeling; core examinations of sedimentary structures and fractures; and a noble gas profile for formation-scale transport of the sealing lihologies and the reservoir. We develop relationships between diagenetic characteristics of lithofacies to mechanical and petrophysical measurements of the caprocks. The results are applied as part of a caprock sealing behavior performance assessment. Funding for this project is provided by the U.S. Department of Energy's National Energy Technology Laboratory through the Southwest Regional Partnership on Carbon Sequestration (SWP) under Award No. DE-FC26-05NT42591.

    Bisulca, Christina

    The research presented in this dissertation covers three separate topics of conservation as defined by the National Science Foundation: 1) Materials Stabilization, Strengthening, Monitoring, and Repair; 2. Understanding Material Degradation and Aging; and 3) Materials and Structural Characterization of Cultural Heritage Objects (the 'technical study'). The first topic is addressed through a study to assess the consolidant tetraethoxysilane for the stabilization of alum treated wood. Falling under materials degradation studies is a study published in American Museum Novitates to understand how environmental conditions affect the aging of fossil resins from five different deposits. Two separate studies are included in technical study of cultural heritage objects which comprises the third research area of materials characterization. The first is a survey of red dyes used in Chinese paintings from the Ming Dynasty to the Early Republic (1364-1911). The second is a study of the pigments, dyes and binders used in Hawaiian barkcloth (kapa) from the 19th century.

    The proportion of Campylobacter contaminated food and water samples collected by different surveillance systems often exhibit seasonal patterns. In addition, the incidence of foodborne campylobacteriosis also tends to exhibit strong seasonal patterns. Of the various product classes, the occurrence of Campylobacter contamination can be high on raw poultry products, and chicken is often thought to be one of the leading food vehicles for campylobacteriosis. Two different federal agencies in the United States collected samples of raw chicken products and tested them for the presence of Campylobacter. During the same time period, a consortium of federal and state agencies operated a nationwide surveillance system to monitor cases of campylobacteriosis in the United States. This study uses a common modeling approach to estimate trends and seasonal patterns in both the proportion of raw chicken product samples that test positive for Campylobacter and cases of campylobacteriosis. The results generally support the hypothesis of a weak seasonal increase in the proportion of Campylobacter positive chicken samples in the summer months, though the number of Campylobacter on test-positive samples is slightly lower during this time period. In contrast, campylobacteriosis cases exhibit a strong seasonal pattern that generally precedes increases in contaminated raw chicken. These results suggest that while contaminated chicken products may be responsible for a substantial number of campylobacteriosis cases, they are most likely not the primary driver of the seasonal pattern in human illness.

  10. Definition of sampling units begets conclusions in ecology: the case of habitats for plant communities

    Full Text Available In ecology, expert knowledge on habitat characteristics is often used to define sampling units such as study sites. Ecologists are especially prone to such approaches when prior sampling frames are not accessible. Here we ask to what extent can different approaches to the definition of sampling units influence the conclusions that are drawn from an ecological study? We do this by comparing a formal versus a subjective definition of sampling units within a study design which is based on well-articulated objectives and proper methodology. Both approaches are applied to tundra plant communities in mesic and snowbed habitats. For the formal approach, sampling units were first defined for each habitat in concave terrain of suitable slope using GIS. In the field, these units were only accepted as the targeted habitats if additional criteria for vegetation cover were fulfilled. For the subjective approach, sampling units were defined visually in the field, based on typical plant communities of mesic and snowbed habitats. For each approach, we collected information about plant community characteristics within a total of 11 mesic and seven snowbed units distributed between two herding districts of contrasting reindeer density. Results from the two approaches differed significantly in several plant community characteristics in both mesic and snowbed habitats. Furthermore, differences between the two approaches were not consistent because their magnitude and direction differed both between the two habitats and the two reindeer herding districts. Consequently, we could draw different conclusions on how plant diversity and relative abundance of functional groups are differentiated between the two habitats depending on the approach used. We therefore challenge ecologists to formalize the expert knowledge applied to define sampling units through a set of well-articulated rules, rather than applying it subjectively. We see this as instrumental for progress in

    Particulate air pollution is known to be associated with cardiovascular disease. The relation of particulate air pollution with cerebrovascular disease (CVD) has not been extensively studied, particularly in relation to different subtypes of stroke. A time-series study was conducted to evaluate the association between daily air pollution and acute stroke unit hospitalizations in Mantua, Italy. We analyzed 781 CVD consecutive patients living in Mantua county admitted between 2006-08. Data on stroke types, demographic variables, risk factors were available from the Lombardia Stroke Registry. Daily mean value of particulate matter with a diameter <10 µm (PM(10)), carbon monoxide, nitric oxide, nitrogen dioxide, sulphur dioxide, benzene and ozone were used in the analysis. The association between CVD, ischemic strokes subtypes and pollutants was investigated with a case-crossover design, using conditional logistic regression analysis, adjusting for temperature, humidity, barometric pressure and holidays. Among the 781 subjects admitted 75.7% had ischemic stroke, 11.7% haemorrhagic stroke 12.6% transient ischemic attack. In men admission for stroke was associated with PM(10) [odds ratio (OR) 1.01, 95%; confidence interval (CI) 1.00-1.02; P<0.05]. According to the clinical classification, lacunar anterior circulation syndrome stroke type was related to PM(10) level registered on the day of admission for both genders (OR: 1.01, 95%; CI: 1.00-1.02; P<0.05) while for total anterior circulation syndrome stroke only in men (OR: 1.04, 95%; CI 1.01-1.07; P<0.05).In conclusion, our study confirms that air pollution peaks may contribute to increase the risk of hospitalization for stroke and particulate matter seems to be a significant risk factor, especially for lacunar stroke.

    Based on various criteria, civil servant pension systems can be divided into different types. Based on comparison between civil servant pension system and other population group's pension system, the civil servant pen- sion system can be divided into fully integration, complete separation and partial integration. Singapore, Germany and the United Kingdom are examples of these three types respectively, with their system model, operating mecha- nism and management systems being different with each other. In terms of the fairness and efficiency, the civil serv- ant pension systems of these countries have their own advantages and disadvantages. The comparative analysis on the civil servant pension systems of these three countries provides the inspiration for the Chinese civil servant pension system reform:the system must be suitable with the condition of our country and equally address the issue of equity and efficiency. It seems that the inevitable choice of the reform is to move towards partial integration.%根据不同的标准,公务员养老保险制度可以分成不同的类型。根据公务员与其他群体养老保险制度的比较,公务员养老保险制度可以分为完全融合型、完全独立型、部分融合型三类。新加坡、德国、英国是这三类公务员养老保险制度的代表,其制度模式、运行机制、管理体制均有所不同。在公平性与效率性方面,三个国家的公务员养老保险制度各有优劣。三国公务员养老保险制度的比较分析,为中国公务员养老保险制度改革提供了启示:必须与我国国情相结合,必须注意公平与效率的结合,走向部分融合是改革的必然选择。

  13. The Prosecution of State-Level Human Trafficking Cases in the United States

    Full Text Available In an effort to combat human trafficking, the United States federal government and all fifty states passed new laws that criminalise human trafficking and support the identification and prosecution of human trafficking perpetrators. Despite the passage of these laws, only a small number of human trafficking cases have been prosecuted in the last fifteen years. Guided by the notion that prosecutors seek to avoid uncertainty when making decisions to pursue criminal prosecution, we explore how human trafficking crimes are indicted under these newly defined state laws. Using a sample of cases from twelve US counties and interviews with police, prosecutors and court personnel, we examine the factors that influence the decision to prosecute crimes investigated as human trafficking in state court. This research informs our understanding of why so few human trafficking cases are prosecuted and why human trafficking suspects are rarely convicted of trafficking offenses.

    Since 1982 when secondary. poisoning of Red-tailed Hawks (Buteo jamaicensis) was documented following the recommended use of famphur on cattle, the Patuxent Wildlife Research Center has tested for organophosphate (OP) poisoning in selected birds of prey found dead. This report documents the circumstances for a number of. cases where birds of prey were killed by OP pesticides in the United States. Many of the cases were brought to our attention by the U S. Fish and Wildlife Service Division of Law Enforcement The cases may be divided into three categories: misuse, approved use, and unknown. Now that we are looking for OP poisoning of birds of prey, we are finding it more frequently than previously suspected.

    Africa is the final continent to be affected by the nutrition transition and, as elsewhere, is characterized by the paradoxical coexistence of malnutrition and obesity. Several features of the obesity epidemic in Africa mirror those in other emerging nations: it penetrates the richer nations and urban areas first with a strong urban- rural gradient; initially it affects the wealthy, but later there is a demographic switch as obesity becomes a condition more associated with poverty, and it shares many of the same drivers related to the increasing affordability of highly refined oils and carbohydrates, and a move away from subsistence farm work and towards sedentary lifestyles. Africa also has some characteristics of the obesity epidemic that stand out from other regions such as: (1) excepting some areas of the Pacific, Africa is probably the only region in which obesity (especially among women) is viewed culturally as a positive and desirable trait, leading to major gender differences in obesity rates in many countries; (2) most of Africa has very low rates of obesity in children, and to date African obesity is mostly an adult syndrome; (3) Africans seem genetically prone to higher rates of diabetes and hypertension in association with obesity than Caucasians, but seem to be relatively protected from dislipidemias; (4) the case-specific deaths and disabilities from diabetes and hypertension in Africa are very high due to the paucity of health services and the strain that the 'double burden' of disease places on health systems.

    Full Text Available The paper presents a case of leishmaniasis in a 2.5-month-old dog imported from France. The clinical examination established a generally poor state of health, expressed cachexia, atrophy of the temporal musculature, weakness of movement, as well as abnormally long and brittle nails. There was also hyperkeratosis of the nose tip and paws. A histological examination of biopsy sections of the altered skin parts showed inflammatory changes in the area of the dermis, together with infiltration of macrophages and a smaller number of lymphocytes, plasmocytes and neutrophil granulocytes in the area around the sebaceous glands and hair follicles. The determined changes correspond to superficial dermatitis. Edema followed by partial degeneration of connective-tissue fibers is observed in connective tissue. A smaller number of intracellular parasitic forms was established in mononuclear cells. A smaller number of oval amastigotes with round dark red nucleis were observed in sections stained using the Gimza method in the cytoplasm of macrophages located in the dermis, but also extracellularly. It was concluded that the dog was diseased with leishmaniasis on the grounds of the clinical picture and the microscopic findings.

    This feasibility study examines a range of alternatives and provides recommendations for selecting a preferred alternative for remediating contamination at the 200-BP-1 operable unit. The 200-BP-1 operable unit is located in the center of the Hanford Site along the northern boundary of the 200 East Area. The 241-BY Tank Farm is located immediately to the south of the operable unit. 200-BP-1 is a source operable unit with contaminated soils associated primarily with nine inactive cribs (known as the 216-B cribs). These cribs were used for disposal of low-level radioactive liquid waste from U Plant uranium recovery operations, and waste storage tank condensate from the adjacent 241-BY Tank Farm. The cribs used for disposal of U Plant waste were in operation from 1955--1965, and the cribs used for disposal of tank condensate were in operation from 1965--1975. In addition to the cribs, four unplanned releases of radioactive materials have occurred within the operable unit. Contaminated surface soils associated with the unplanned releases have been consolidated over the cribs and covered with clean soil to reduce contaminant migration and exposure. Discharge of wastes to the cribs has resulted in soil and groundwater contamination. The groundwater is being addressed as part of the 200 East Aggregate Area, groundwater operable unit. Contaminated soils at the site can be categorized by the types of contaminants, their distribution in the soil column, and the risk posed by the various potential exposure pathways. Below the clean soil cover, the near surface soils contain low-levels of contamination with cesium-137, radium-226, strontium-90, thorium-228, and uranium. The lifetime incremental cancer risk associated with these soils if they were exposed at the surface is 9{times}10{sup {minus}5}.

    Internationally, there is no consensus on how to best deal with admission requests in cases of full ICU bed occupancy. Knowledge about the degree of dissension and insight into the reasons for this dissension is lacking. Information about the opinion of ICU physicians can be used to improve decision-making regarding allocation of ICU resources. The aim of this study was to: Assess which factors play a role in the decision-making process regarding the admission of ICU patients; Assess the adherence to a Dutch guideline pertaining to rationing of ICU resources; Investigate factors influencing the adherence to this guideline. In March 2013, an online questionnaire was sent to all ICU physician members (n = 761, in 90 hospitals) of the Dutch Society for Intensive Care. 166 physicians (21.8 %) working in 64 different Dutch hospitals (71.1 %) completed the questionnaire. Factors associated with a patient's physical condition and quality of life were generally considered most important in admission decisions. Scenario-based adherence to the Dutch guideline "Admission request in case of full ICU bed occupancy" was found to be low (adherence rate 50.0 %). There were two main reasons for this poor compliance: unfamiliarity with the guideline and disagreement with the fundamental approach underlying the guideline. Dutch ICU physicians disagree about how to deal with admission requests in cases of full ICU bed occupancy. The results of this study contribute to the discussion about the fundamental principles regarding admission of ICU patients in case of full bed occupancy.

    The aim of a series of sessions on Company Case Studies, is to learn from practical experiences, to give feed back to researchers on applicability of theories, methods and techniques, and last but not least, to market ergonomics. In order to learn from case material, reports need to be easy accessible and well structured. System ergonomics provides such a structure. Usually a project is not done twice, i.e. with and without ergonomics. Therefore, it is not possible to make comparisons and determine the impact of ergonomics directly. A different approach is needed. It has been suggested at the IEA2006 World Congress, to compile a database of published case studies, each case to be reported in a fixed report format and critically reviewed to enable generalizing the outcomes. This paper proposes such a format. At the IEA2012 World Congress 40 case studies have been accepted, representing applied ergonomics cases in manufacturing, process industries, aviation and logistic systems.

    2009-07-01

    Recent developments in case study methodology reflect a rising interest that clinicians and researchers share in building a clinically useful and empirically sound knowledge base from single-case studies. The present article describes three types of single-case studies (clinical, experimental, systematic) and examines their potential contributions to psychotherapy research. It then lays out three ways in which single-case studies can be aggregated and synthesized to enhance clinical understanding: (a) a case database that allows clinicians to efficiently search for relevant cases, (b) a metasynthesis of single-case studies that integrates common themes across similar cases, and (c) an individual case comparison method in which closely matched cases are compared to identify both therapeutic and hindering processes.

    Ergotamine is a well known pharmacological remedy applied in neurology (treatment of vascular headache) and in obstetrics (abortive remedy, uterus atony). But today it is rarely used, because of new safer anti-migraine medicine (triptanes) which cause fewer side effects. According to obstetrical indications ergotamine is applied only in hospital treatment. For that reason, cases of intoxication by this class of drugs are rarely observed. Ergotamine causes constriction of the blood vessels through the blockade of alpha-receptors and stimulation of the serotonin-receptors on the walls of blood vessels both in the central nervous system and in peripheral circulation. Intoxication/overdose symptoms may appear on application of therapeutic dose by sensitive patients, mostly by patients with migraine headache using ergotamine preparation for relief of migraine attacks. In the Regional Centre of Clinical Toxicology, a 21-year-old patient was hospitalized. She took about 20 tablets of Cafergot (complex preparation containing 1mg ergotamine tartare and 100mg caffeine). During her stay on the ward, typical symptoms of severe poisoning were observed: nausea, severe vomiting, dizziness, decreased blood pressure without perceptible pulse, narrowing of the blood vessels in the extremities of the body (peripheral vasoconstriction) - paresthesia, digital cyanosis, refrigeration of legs, angina. Due to taking once of a great dose of the drug by the patient, violent process of intoxication, possibility of dangerous complication and also the unavailability of specific antidotes and lack of efficient methods of extracorporeal elimination of the drug, the patient was intensively controlled and symptomatic treatments according to the law of intensive therapy was applied.

    The multifamily case studies that are the subject of this report were conducted to provide a better understanding of the approach taken by program operators in weatherizing large buildings. Because of significant variations in building construction and energy systems across the country, five states were selected based on their high level of multifamily weatherization. This report summarizes findings from case studies conducted by multifamily weatherization operations in five cities. The case studies were conducted between January and November 1994. Each of the case studies involved extensive interviews with the staff of weatherization subgrantees conducting multifamily weatherization, the inspection of 4 to 12 buildings weatherized between 1991 and 1993, and the analysis of savings and costs. The case studies focused on innovative techniques which appear to work well.

    The aim of this study is to provide an overview of the scientific activity of different psychoanalytic schools of thought in terms of the content and production of case studies published on ISI Web of Knowledge. Between March 2013 and November 2013, we contacted all case study authors included in the online archive of psychoanalytic and psychodynamic case studies (www.singlecasearchive.com) to inquire about their psychoanalytic orientation during their work with the patient. The response rate for this study was 45%. It appears that the two oldest psychoanalytic schools, Object-relations psychoanalysis and Ego psychology or "Classical psychoanalysis" dominate the literature of published case studies. However, most authors stated that they feel attached to two or more psychoanalytic schools of thought. This confirms that the theoretical pluralism in psychoanalysis stretches to the field of single case studies. The single case studies of each psychoanalytic school are described separately in terms of methodology, patient, therapist, or treatment features. We conclude that published case studies features are fairly similar across different psychoanalytic schools. The results of this study are not representative of all psychoanalytic schools, as some do not publish their work in ISI ranked journals.

    Coals in the eastern United States (east of the Mississippi River) have been the subject of a number of coal facies studies, going back to the 19th century. Such studies would not necessarily fall within a strict modern classification of coal facies studies, but if a study encompassed some aspects of paleobotany, palynology, petrology, geochemistry, or sedimentology, we assumed that some data and interpretations may be of use in evaluations of the facies. References are presented, as a guide for further research, with annotation in the tables.

    Full Text Available This paper describes the potential suitability of case study methodology for inquiry with the homeless population. It references a research study that uses case study research method to build theory. This study's topic is the lived experience of destitute individuals who reside in homeless shelters, and explores the homeless shelter built environment's potential influence on resident satisfaction and recovery. Case study methodology may be appropriate because it explores real-life contextual issues that characterize homelessness and can also accommodate the wide range of homeless person demographics that make this group difficult to study in a generalized fashion. Further, case study method accommodates the need within research in this area to understand individualized treatments as a potential solution for homelessness.

    This paper discusses the use of bioremediation as an effective method to clean up diesel-range hydrocarbon spills in northern latitudes. The results of a laboratory study of microbial degradation of hydrocarbons under simulated arctic conditions showed that bioremediation can be effective in cold climates and led to the implementation of a large-scale field program. The results of 3 years of field testing have led to a significant reduction in diesel-range hydrocarbon concentrations in the contaminated area.

  17. Two cases of burns caused by misuse of coagulation unit and monitoring.

    Rolly, G

    1978-01-01

    Two cases of severe burns with monitoring apparatus are described. In a female patient of 45 years, a severe third degree burn occurred by misuse of coagulation apparatus (inversion of the poles of an older Bovie apparatus), in the presence of a non-floating ECG monitoring device. A high intensity current was established from the coagulation unit, via the earth plate under the buttocks, to the indifferent electrode placed on the chest, where burns occurred. In an 8 month female baby, having laparotomy for a neuroblastoma, a third degree burn of 5 cm diameter occurred with a non-floating ECG monitor. A twin-wired disposable earth plate was placed just beneath the indifferent ECG electrode on the leg. A burning current was established between the Bovie coagulation unit and the monitor.

    Full Text Available We report a case of massive associative visual agnosia. In the light of current theories of identification and semantic knowledge organization, a deficit involving both levels of structural description system and visual semantics must be assumed to explain the case. We suggest, in line with a previous case study [1], an alternative account in the framework of (non abstractive episodic models of memory [4].

  19. A sociological study of bed blocking in psychiatric rehabilitation units.

    Science.gov (United States)

    Leighton, Kevin

    2002-08-01

    This study focuses on the reported problem of psychiatric patients who are 'bed-blocking' mental health rehabilitation units. It explores the concept of individualized care within psychiatric nursing and argues that this 'received view' is counterproductive for some client groups. Individualized care assumes a number of mainstream social values and beliefs that may conflict radically with the attitudes to life (ideologies) of some service users. These clients may resist normalisation, independence and individualism, preferring instead a more collective, pastoral and spiritual lifestyle. Clients and nurses may reject culture-biased care policy, using various strategies to neutralize individualized care in practice. In the absence of a coherent alternative, such action may lead to frustration, alienation and bed blocking. The study uses structured and unstructured interviews in two psychiatric units to examine this hypothesis.

    Lemierre syndrome is a rare but serious illness that associates throat infection and thrombosis of the internal jugular vein (IJV) or one of its tributaries with subsequent distant septic emboli. The purpose of our study was to review the pathogenesis, clinical presentation, and treatment of this disease. Patients with confirmed Lemierre syndrome were included in our retrospective monocentric study. All patients had bacteriologic analyses as well as radiologic imaging. There were 11 patients in our study (from 1998-2012). Fusobacterium necrophorum was responsible for the infection in 45% of cases. Surgical drainage of pharyngeal, cervical, or mediastinal abscesses was carried out in 8 cases. All patients received broad-spectrum antibiotics. Six patients were admitted to the intensive care unit (ICU). One patient (9%) died. Treatment with broad-spectrum antibiotics is the primary choice of treatment of Lemierre syndrome. Surgery is indicated in case of abscess formation. Copyright © 2013 Wiley Periodicals, Inc.

    Full Text Available This research reviews the literature on case study as a strategic qualitative research methodology. Although case studies have been criticised by some authors as lacking scientific rigour and do not address generalizability, this research, however, reiterated its appropriateness when dealing with a process or a complex real-life activities in great-depth. Case study has been commonly used in social science fields like sociology, industrial relations and anthropology eventhough generally was considered an underutilized strategy. Hence, this research explained the general concept of a case study, strengths and weaknesses of using this method knowing that theoretically case is exciting and data rich. Based on a study of four organizations and the researcher’s own experience, this article described matters on how case study was undertaken, gaining excess to those organizations and the systematic process of data collection and triangulation (multiple techniques. It was noted that combining multiple techniques for elicitng data in case study research actually strengthens and confirmed results.

    Full Text Available Through these lines it is presented a qualitative investigation in a rural school according to the Physical Education subject. The aim of this investigation is to check if there are any meaningful differences in the teaching of acrosport in accordance with the methodology used: cooperative learning and task assignment. To that effect, different instruments have been used in order to tally the information, which is: a ranking to see the social relationships among students, a practical exam, a pupil’s term evaluation sheet, a motivational question paper and a teacher’s notebook. Among the results, it could be observed an improvement in the social relationships ranking, in the creative learning and in the perception of the participation of cooperative learning groups. There are some individual facts in these groups where the acceptance from partners and the sense of acceptance from the learner improve with the cooperative learning. These results are similar to other studies which are longer.

    Full Text Available Background. Polyorchidism, alternatively supernumerary testes (SNT, is a condition where an individual is born with more than two testicles. This congenital anomaly is quite rare and the literature has described various presentations. Questions/Purposes. To our knowledge, this presentation of polyorchidism has yet to be described in the literature. The goal of this case study is to add to the pediatric, general, and urologic surgery’s body of knowledge of the subject matter. Case Study. A nine-month-old boy was admitted for an impalpable right testis and phimosis. At the time of surgical exploration, there appeared to be polyorchid testis on the right-hand side, with three masses that potentially appeared to be undescended testes. Discussion. Proponents of a conservative approach argue that infertility is common in patients with polyorchidism and, by preserving a potentially functional SNT, there may be improved spermatogenesis. When performing definitive surgical treatment, meticulous intra-abdominal and intrainguinal exploration must be undertaken. Orchiopexy should be performed to reduce the chances of torsion, malignancy, and infertility. Conclusion. Our case is important to the literature as it is the first known case of polyorchidism with 3 SNT on the right side, located intra-abdominally, and in a patient less than 1 year of age.

Despite such achievements the gapbetween demand and supply of electrical energy is increasingevery year and power sector is highly capital – intensive. Thusthe deficit in installed capacity was nearly 10000MWper year.So the gap between demand and supply is continuouslyincreasing day by day. An energy audit is a study of a plant orfacility to determine how and where energy is used and toidentify methods for energy savings. The opportunities lie inthe use of existing renewable energy technologies, greaterefforts at energy efficiency and the dissemination of thesetechnologies and options. This thesis provides an overview of ageneral energy conservation measures (ECMs that can becommonly recommended for NIT Hamirpur. It should be notedthat the Energy auidut presented in this paper does not pretendto be exhaustive nor comprehensive. It provides merely toindicate some of the options that energy auditor can considerwhen performing an analysis of this institute. Energyconservation and exploration of new energy avenues are thewell accepted solution to fulfil the demand in future. The totalcost of energy plays a vital role in determining the product costof a commodity. Therefore the identification of potential energysavings and implementation for a given institutional facility isunimportant to ensure its competitive advantage over otherinstitute. This paper work presents such energy saving methodsin a methodological approach, experienced during a detailedenergy audit of NIT Hamirpur.

    Full text: A forty-two-year-old male presented to the Royal Adelaide Hospital with symptoms of increasing shortness of breath, swelling in both ankles, petechial rash and blood in his sputum. Initial investigations showed cardiomegaly, right ventricular hypertrophy, patchy lung infiltrates, a platelet count of 1500 and a clotting time of 60 seconds. A V/Q scan indicated a high probability of pulmonary embolism. Further investigations showed that the patient was positive for lupus anticoagulant and cardiolipin antibodies. A diagnosis of primary antiphospholipid syndrome was made. The patient``s high risk of strokes and hemorrhaging prompted investigation by a {sup 99}mTc-HMPAO brain scan. Further V/Q scans were performed to follow up the initial finding of multiple pulmonary embolism and a R-L shunt study was performed to investigate a left subclavian murmur. The patient was admitted for four weeks and began treatment which included cyclaphosphamide, corticosteroids and plasmaphoresis and was discharged when stable. Over the next six months he was re admitted three times for relapse of antiphospholipid syndrome. On his fourth admission he collapsed and died five hours after admission. Cause of death was due to cardiac arrhythmia secondary to severe right ventricular hypertrophy and dilation. The effects of antiphospholipid syndrome was believed to be responsible for this outcome.

    Full Text Available Modern educational technologies are based on competence approach and focus on the future professional activity. Case study is one of the most significant technologies in modern higher education. The basic concepts used in the case study method are a “situation” and an “analysis”, as well as their derivative - “analysis of the situation”. The case study method of is one of the best tools for gaining experience, as it investigates practical situations that occur in managerial job. It combines theoretical knowledge with the analysis of the actual practical experience in accordance with a major. Doing case studies students read the description of the situation and offer divergent projects of managerial decisions that could be used by real managers dealing with the problem posed by the case study author. Answers to the questions posed in the case description are not given, as a rule, since the main purpose in the case analysis is to organize a discussion in the classroom or provoke speculations of those who do the self-study.

    Full Text Available Introduction. Hot water bottles are commonly used to relieve pain and for warmth during the colder months of the year. However, they pose a risk of serious burn injuries. The aim of this study is to retrospectively review all burn injuries caused by hot water bottles presenting to our regional burns unit. Methods. Patients with burns injuries resulting from hot water bottle use were identified from our burns database between the periods of January 2004 and March 2013 and their cases notes reviewed retrospectively. Results. Identified cases involved 39 children (aged 17 years or younger and 46 adults (aged 18 years or older. The majority of burns were scald injuries. The mean %TBSA was 3.07% (SD ± 3.40. Seven patients (8.24% required debridement and skin grafting while 3 (3.60% required debridement and application of Biobrane. One patient (1.18% required local flap reconstruction. Spontaneous rupture accounted for 48.20% of injuries while accidental spilling and contact accounted for 33% and 18.80% of injuries, respectively. The mean time to heal was 28.87 days (SD ± 21.60. Conclusions. This study highlights the typical distribution of hot water bottle burns and the high rate of spontaneous rupture of hot water bottles, which have the potential for significant burn injuries.

  8. Towards More Case Study Research in Entrepreneurship

    Directory of Open Access Journals (Sweden)

    Tom Duxbury

    2012-03-01

    Full Text Available Entrepreneurship as an emerging discipline has made good strides, but according to some, has fallen short of bringing its theory and literature up to the standards of others in the management sciences. Rich with the descriptive detail needed for insightful theory building in entrepreneurship, scholars have called for more case study research, particularly those incorporating non-retrospective and longitudinal observations. At the same time however, it has become rare to find such research published in A-level journals dedicated to entrepreneurship. A survey presented here of major entrepreneurship journals over the past six years revealed a publication rate of only 3% using the case study method. This presents a major impediment for developing fresh research in this field based upon the study of real cases. The author explores how the case study method has been applied to entrepreneurship research and provides recommendations for improved publication rates.

  9. Two Case Reports of Neuroinvasive West Nile Virus Infection in the Critical Care Unit

    Directory of Open Access Journals (Sweden)

    Edgardo M. Flores Anticona

    2012-01-01

    Full Text Available We describe the clinical course of two cases of neuroinvasive West Nile Virus (WNV infection in the critical care unit. The first case is a 70-year-old man who presented during summer with mental status changes. Cerebrospinal fluid (CSF analysis revealed pleocytosis with lymphocyte predominance. WNV serology was positive in the CSF. His condition worsened with development of left-sided weakness and deterioration of mental status requiring intensive care. The patient gradually improved and was discharged with residual left-sided weakness and near-complete improvement in his mental status. The second case is an 81-year-old man who presented with mental status changes, fever, lower extremity weakness, and difficulty in walking. CSF analysis showed pleocytosis with neutrophil predominance. WNV serology was also positive in CSF. During the hospital stay his mentation worsened, eventually requiring intubation for airway protection and critical care support. The patient gradually improved and was discharged with residual upper and lower extremity paresis. Neuroinvasive WNV infection can lead to significant morbidity, especially in the elderly. These cases should be suspected in patients with antecedent outdoor activities during summer. It is important for critical care providers to be aware of and maintain a high clinical suspicion of this disease process.

    2001-12-01

    We determined the results of shock wave lithotripsy with a newer electromagnetic lithotriptor and compared them with those in a contemporary series of cases managed by an electrohydraulic lithotriptor using identical treatment and followup criteria at a single center. Between 1995 and 1999, 356 patients (375 renal units, 483 upper urinary tract stones) meeting study inclusion criteria were treated with an MFL 5000 electrohydraulic shock wave lithotripsy unit (Dornier Medical Systems, Inc., Marietta, Georgia). From 1999 to 2000, 173 patients (175 renal units; 218 upper urinary tract stones) meeting identical study inclusion criteria were treated using an electromagnetic Modulith SLX shock wave lithotripsy unit (Karl Storz Lithotripsy, Atlanta, Georgia). In each group stone-free results were determined by plain abdominal x-ray and renal ultrasound 1 month after lithotripsy and efficiency quotients were developed. Baseline patient and stone characteristics were compared by the Wilcoxon rank sum and Fisher exact tests. All variables significant at p electromagnetic lithotripsy units (0.45 and 0.42, respectively, p = 0.43). Electrohydraulic lithotripsy resulted in a higher stone-free rate at 1 month, although it was associated with a higher rate of auxiliary measures. Ultimately the efficiency quotients were equivalent, implying that these 2 contemporary energy sources are acceptable. According to single center treatment and followup criteria they are equally efficacious.

In addition, the economizer exit gas temperature has been too high, and the reheat surface has become routinely fouled. To determine the cause of these problems and to find possible solutions, NPPD contracted with a boiler manufacturer to review results of a recent performance test on the boiler and offer possible solutions. Some of the solutions offered by the boiler manufacturer were unrealistic, while others offered some promise. In early 1994, NPPD and Performance Engineering, Inc. (PEI) reviewed the results of the boiler manufacturer using a PEPSE (Performance Evaluation of Power System Efficiencies) model originally developed by NPPD and later modified by PEI. In addition, solutions not offered by the boiler manufacturer were studied. Results of the PEPSE study showed that increases to the reheat and superheat surface areas would increase the steam temperatures to the design levels while decreasing the gas temperature leaving the economizer. However, the studies also showed that keeping the surfaces clean would produce the same effect as adding more area without the capital investment. The results of the PEPSE study on GGS1 are presented and solutions are offered. A discussion of the PEPSE model and modeling techniques used for this study are also presented.

    Ground-source heat pump systems are one of the promising new energy technologies that has shown rapid increase in usage over the past ten years in the United States. These systems offer substantial benefits to consumers and utilities in energy (kWh) and demand (kW) savings. The purpose of this study was to determine what existing monitored data was available mainly from electric utilities on heat pump performance, energy savings and demand reduction for residential, school and commercial building applications. In order to verify the performance, information was collected for 253 case studies from mainly utilities throughout the United States. The case studies were compiled into a database. The database was organized into general information, system information, ground system information, system performance, and additional information. Information was developed on the status of demand-side management of ground-source heat pump programs for about 60 electric utility and rural electric cooperatives on marketing, incentive programs, barriers to market penetration, number units installed in service area, and benefits.

    Full Text Available The dissociative identity disorder (DID can be considered a rare disorder because of its seemingly low prevalence. However, in recent years it points to the possible underdiagnosis because its complexity and confusion at the time of differential diagnosis. On the other hand, the malingering of mental psychopathology can have a major socio-economic and legal impact, particularly important in this type of disorder, given the inability it generates and its complex diagnostic. This paper refers the case of a patient admitted to the short-term hospitalization unit of Dr. Rodríguez Lafora Hospital (Madrid with depressive symptoms. Then the patient seemed to become a TID case. The evaluation consisted of a psychological history and the application of the Structured Inventory of Malingered Symptoms (SIMS and the Millon Clinical Multiaxial Inventory (MCMI-II. The results showed an altered personality profile as well as likely malingered symptoms, what prevented us from a DID diagnosis. In view of the results, possible implications of this case for the clinical setting are discussed.

    Many poisoned patients may only require a period of observation after their exposure. There are limited data describing the use of observation units for managing poisoned adult and pediatric patients. We performed a retrospective review of all patients reported to the ToxIC Case Registry between January 1, 2012 and December 31, 2013. Eligible patients included those who received a bedside consultation by a medical toxicologist and whose care was provided in an observation unit, or those who were admitted under the care of a medical toxicologist in an observation unit. A total of 15,562 poisonings were reported to the registry during the study period, of which 340 (2.2 %) involved patients who were cared for in an observation unit. Of these patients, 22.1 % were 18 years of age or younger, and the remaining 77.9 % were greater than 18 years of age. The most common reason for exposure was the intentional ingestion of a pharmaceutical agent in both adult (30.2 %) and pediatric patients (36.0 %). Alcohols (ethanol) (24.9 %), opioids (20.0 %), and sedative-hypnotics (17.7 %) were the most common agent classes involved in adult patient exposures. The most common agent classes involved in pediatric exposures were antidepressants (12.0 %), anticonvulsants (10.7 %), and envenomations (10.7 %). In adult patients, the most common signs and symptoms involved the nervous system (52.0 %), a toxidrome (17.0 %), or a major vital sign abnormality (14.7 %). In pediatric patients, the most common signs and symptoms involved the nervous system (53.3 %), a toxidrome (21.3 %), or a major vital sign abnormality (17.3 %). The results of this study demonstrate that a wide variety of poisoned patients have been cared for in an observation unit in consultation with a board-certified medical toxicologist. Patterns for the reasons for exposure, agents responsible for the exposure, and toxicological treatments will continue to evolve. Further study is needed to identify

    1984-01-01

    The vitreous of three patients with asteroïd hyalosis (average age: 57 years) was obtained by a two-hand closed pars plana vitrectomy. Asteroïd hyalosis was associated with alcoholic neuropathy in the first case, long standing retinal detachment in the second case, and diabetes mellitus in the third case. The visual acuity before and after the surgical procedure improved from 1.2/6 to 6/6 in the first case, from light perception to 0.3/6 in the second case, from 0.6/6 to 4.8/6 in the third case. The vitreous was studied by different ultrastructural technics : transmission electron microscopy (T.E.M.) scanning electron microscopy (S.E.M.) and electron diffraction X ray analysis (E.D.A.X.). By S.E.M. the asteroïd bodies appeared as rounded structures with an irregular surface connected to each other by fibrous strands among sodium chloride crystals. No cellular remnants were observed. By T.E.M. the asteroïd bodies were composed of interwinned ribbons of multilaminar membranes with a periodicity (10 to 60 A) characteristic of complex lipids, especially phospholipids. At the edge of the ribbons there were dots and sometimes clumps of opaque material that tended to crack out of the specimen with the heat of the electron beam. T.E.M. study disclosed the irregular disposition of the calcific bodies. By E.D.A.X. the calcific composition of the rounded structures could be determined : calcium and phosphorus were the main elements detectable in asteroïd bodies of all sizes for all three patients. The average calcium counts for the three successive cases were : 18, 30, 43 and for phosphorus : 9, 14, 26. Potassium was found in the first case, and sulfur in the third case.(ABSTRACT TRUNCATED AT 250 WORDS)

    Full Text Available Food innovation and entrepreneurship are important topics in graduate food studies. Students should be challenged to promote an innovative attitude towards their future career in the food industry sector, as professionals working in a small and medium-sized enterprise, or in a large multinational company, or even as entrepreneurs with their own working projects. The present case study shows a curricular unit of a master course that intends to integrate the knowledge on new and sustainable technologies and products, based on seminars of experts on hot topics, on visits to food industry enterprises and market expositions and on the development of a state-of-the-art report about an emergent or novel food technology or product with oral presentation. Hot topic seminars included edible coatings, bioprocessing, allying tradition and innovation in food products, new convenience foods, challenging tests, and new clean and sustainable processes. Entrepreneur alumni lectures were also promoted allowing exchange of experiences. Visits included a high pressure technology unit of a food industry, an innovation and development department of a food industry, an entrepreneurship centre and a food exhibition. A satisfaction survey was made, through the response of a questionnaire by the students, proving the effectiveness and success of this unit course framework. A SWOT analysis was carried out to gain a better understanding of the strengths, weaknesses, opportunities, and threats involved in the curricular unit objectives.

    2002-01-01

    The major goal of this research case study was to investigate the effectiveness of Virtual Reality Therapy (VRT) in the treatment of the fear of public speaking. A twenty-eight-year-old Caucasian male was selected from questionnaires distributed to a class of undergraduate students enrolled at Kennesaw State University. Two assessment measures were used in this study. The first measure used was the Attitude Towards Public Speaking (ATPS) Questionnaire. The second measure used was the eleven-point Subjective Units of Disturbance (SUD) scale. These measurements assessed the anxiety, avoidance, attitudes and disturbance associated with the subject's fear of public speaking before and after each VRT treatment session. This case study of public speaking fear indicates that VRT may be used as an effective treatment method for reducing self-reported anxiety.

    Full Text Available Over the last forty years, case study research has undergone substantial methodological development. This evolution has resulted in a pragmatic, flexible research approach, capable of providing comprehensive in-depth understanding of a diverse range of issues across a number of disciplines. Change and progress have stemmed from parallel influences of historical transformations in approaches to research and individual researcher's preferences, perspectives, and interpretations of this design. Researchers who have contributed to the development of case study research come from diverse disciplines with different philosophical perspectives, resulting in a variety of definitions and approaches. For the researcher new to using case study, such variety can create a confusing platform for its application. In this article, we explore the evolution of case study research, discuss methodological variations, and summarize key elements with the aim of providing guidance on the available options for researchers wanting to use case study in their work.

  17. Nanomaterial Case Study: A Comparison of Multiwalled ...

    Science.gov (United States)

    The draft document is intended to be used as part of a process to identify what is known and, more importantly, what is not yet known that could be of value in assessing the broad implications of specific nanomaterials. Like previous case studies (see History/ Chronology below), this draft case study on multiwalled carbon nanotubes (MWCNTs) is based on the comprehensive environmental assessment (CEA) approach, which consists of both a framework and a process. Unlike previous case studies this case study incorporates information about a traditional (i.e., “non-nano-enabled”) product, against which the MWCNT flame-retardant coating applied to upholstery textiles (i.e., the “nano-enabled” product) can be compared. The comparative element serves dual-purposes: 1) to provide a more robust database that facilitates identification of data gaps related to the nano-enabled product and 2) to provide a context for identifying key factors and data gaps for future efforts to evaluate risk-related trade-offs between a nano-enabled and non-nano-enabled product. This draft case study does not represent a completed or even a preliminary assessment of MWCNTs; rather, it uses the CEA framework to structure information from available literature and other resources (e.g., government reports) on the product life cycle, fate and transport processes in various environmental media, exposure-dose characterization, and impacts in human, ecological, and environmental receptors.

    Green roof construction in the United States is growing at a rate of 60 to 80 per cent per year. This paper presented two case studies of green roof construction in Minnesota. In both cases, construction and budgeting delays moved the installation of the green roofs from early-May to mid-July. The first case study was a 20,000 square foot extensive green roof on the new Minneapolis Central Library which was completed in 2005. The second case study was a 30,000 square foot extensive green roof on the Mdewakanton Sioux Waste Water Treatment Plant in Shakopee, which was completed in 2006. This paper demonstrated that in order for green roofs to serve the functions for which they were intended, clear guidelines and specifications are needed to ensure that they are healthy. The size and locations of the two roofs were quite different, but they were identical in terms of waterproofing. State-of-the-art inverted hot-applied roof membrane technology was used in both roofs along with sub-surface irrigation systems. A mycorrhizae fungi was used in both cases to amend the growing medium. Both roofs used a diverse pallet of native and traditional sedum plant material. This paper highlighted preventative measures taken to ensure the successful installation and establishment of the two roofs built during extreme heat and drought-like conditions. The positive results confirm that it is possible to install green roofs during extremely harsh summer conditions. 9 refs., 4 tabs., 3 figs.

    Full Text Available This case study examines two 10th-grade US History teachers who collaborated to create and implement an integrated, thematic eight-week unit on war with an emphasis differentiated instruction. Drawing on the National Council for the Social Studies (2010 framework for powerful and purposeful social studies instruction, the case study uses multiple sources of data, including 38 lesson observations, analyses of the teachers’ lesson plans and student work, and interviews of teachers. Initially, the teachers were successful at engaging students in simulations, small-group discussions, and higher-order thinking. As the unit progressed, however, the teachers reverted to transmission-style teaching with an emphasis on breadth over depth. Changing teaching practice requires overcoming barriers associated with prior experiences and deeply-held beliefs about teaching and learning.

    Breeman, Wim

    2009-01-01

    The port of Rotterdam, The Netherlands, is the world's largest container port. In 2006, one of these containers caused a chemical incident. Methylbromide is used in some countries as a pesticide for the fumigation of maritime containers. Because of an insufficiently performed detoxification, this insecticide intoxicated several employees and some of the ambulance crew and Mobile Medical Team (MMT). The victims displayed symptoms of sore throat, irritated eyes, and hypersalivation. One of the victims suffered from multiple epileptic seizures. Two victims were admitted to the intensive care unit for respiratory support. Three other employees showed milder symptoms and received supportive care but were not admitted to the hospital. This complicated case shows that the safety of the ambulance crew and MMT must be guaranteed. It also demonstrates that healthcare providers cannot always oversee the accident scene and that there are some pitfalls that are almost impossible to prevent.

Materials and methods: A retrospective, observational and descriptive study that included patients operated in the Otorhinolaryngology Unit of the Northwest National Medical Center, Sonora, from August 2014 to August 2015. Fifty-two (52 complete clinical records of consecutive series of cases were reviewed, out of which 57% were men with an average age of 56.2 years old. Descriptive statistics was used to characterize the distribution, and the differences were evaluated by chi-square test and Student’s t-test. Results: Seventy-one percent (71% of the patients underwent surgery in an operating room and 29% in the ICU. In the latter, more than half of the cases had a tracheostomy (51.92%. Prolonged intubation was the main cause of 51% of the tracheostomy procedures. Complications reached 34.61% of the cases and included the following disorders in descending order: cannula occlusion, peristomal emphysema, hemorrhage, bilateral pneumothorax, decanulation and innominate fistula. These complications were significantly associated with obesity, prolonged endotracheal intubation and general anesthesia. Mortality occurred in 7.69% of the patients. Conclusions: No significant difference was found between complications occurred in an operating room and the ICU. Prolonged mechanical ventilation was the primary indication for tracheotomy. Decannulation was the main cause of complication. Moreover, BMI was a risk factor for complications. The mortality rate was 7.69%, which was more elevated compared to other studies.

    Sturgeons and paddlefish are freshwater fish which are highly valued for their caviar. Despite the fact that every single species of sturgeon and paddlefish is listed under CITES, there are reports of illegal trade in caviar where products are deliberately mislabeled. Three samples of caviar purchased in the United Kingdom were investigated for accurate CITES labeling using COI and cyt b sequencing. Initial species identification was carried out using BLAST followed by phylogenetic analyses using both maximum parsimony and maximum likelihood methods. Results showed no evidence for mislabeling with respect to CITES labels in any of the three samples, but we observed clear evidence for a case of misleading the customer in one sample.

    ABSTRACT OBJECTIVE To test the association between diabetes and tuberculosis. METHODS It is a case-control study, matched by age and sex. We included 323 new cases of tuberculosis with positive results for bacilloscopy. The controls were 323 respiratory symptomatic patients with negative bacilloscopy, from the same health services, such as: ambulatory cases from three referral hospitals and six basic health units responsible for the notifications of new cases of tuberculosis in Salvador, Bahia. Data collection occurred between 2008 and 2010. The instruments used were structured interview, including clinical data, capillary blood glucose (during fasting or postprandial), and the CAGE questionnaire for screening of abusive consumption of alcohol. Descriptive, exploratory, and multivariate analysis was performed using conditional logistic regression. RESULTS The average age of the cases was 38.5 (SD = 14.2) years and of the controls, 38.5 (SD = 14.3) years. Among cases and controls, most subjects (61%) were male. In univariate analysis we found association between the occurrence of diabetes and tuberculosis (OR = 2.37; 95%CI 1.04–5.42), which remained statistically significant after adjustment for potential confounders (OR = 3.12; 95%CI 1.12–7.94). CONCLUSIONS The association between diabetes and tuberculosis can hinder the control of tuberculosis, contributing to the maintainance of the disease burden. The situation demands increasing early detection of diabetes among people with tuberculosis, in an attempt to improve disease control strategies. PMID:28099656

    2012-01-01

    As a continuation from summer 2012, the Shuttle Case Study Collection has been developed using lessons learned documented by NASA engineers, analysts, and contractors. Decades of information related to processing and launching the Space Shuttle is gathered into a single database to provide educators with an alternative means to teach real-world engineering processes. The goal is to provide additional engineering materials that enhance critical thinking, decision making, and problem solving skills. During this second phase of the project, the Shuttle Case Study Collection website was developed. Extensive HTML coding to link downloadable documents, videos, and images was required, as was training to learn NASA's Content Management System (CMS) for website design. As the final stage of the collection development, the website is designed to allow for distribution of information to the public as well as for case study report submissions from other educators online.

    In this paper, the solution of the power flow for unbalanced three phase microgrids systems is proposed. The study aims at the integration of inverter interfaced units using the control law used for primary voltage and frequency regulation, so as to take into account possible small variations...... of these parameters to account for sudden load changes. The proposed study deals with unbalanced systems which is the typical case of small distribution systems and shows how the power losses term varies as the regulators parameters vary as well, thus showing that these are sensitive parameters that could have...... an important role in optimal management of such systems....

  16. [Phenylephrine dosing error in Intensive Care Unit. Case of the trimester].

    Science.gov (United States)

    2013-01-01

    A real clinical case reported to SENSAR is presented. A patient admitted to the surgical intensive care unit following a lung resection, suffered arterial hypotension. The nurse was asked to give the patient 1 mL of phenylephrine. A few seconds afterwards, the patient experienced a hypertensive crisis, which resolved spontaneously without damage. Thereafter, the nurse was interviewed and a dosing error was identified: she had mistakenly given the patient 1 mg of phenylephrine (1 mL) instead of 100 mcg (1 mL of the standard dilution, 1mg in 10 mL). The incident analysis revealed latent factors (event triggers) due to the lack of protocols and standard operating procedures, communication errors among team members (physician-nurse), suboptimal training, and underdeveloped safety culture. In order to preempt similar incidents in the future, the following actions were implemented in the surgical intensive care unit: a protocol for bolus and short lived infusions (<30 min) was developed and to close the communication gap through the adoption of communication techniques. The protocol was designed by physicians and nurses to standardize the administration of drugs with high potential for errors. To close the communication gap, repeated checks about saying and understanding was proposed ("closed loop"). Labeling syringes with the drug dilution was also recommended.

    2016-01-01

    Background: Biotinidase deficiency (BD) is a rare, inherited autosomal recessive disorder that is treatable within childhood. We present a patient with pneumonia and respiratory acidosis who was not diagnosed with any systemic disorders; the patient was finally diagnosed as BD. Case Report: A thirty-year-old woman was admitted to the emergency department with respiratory failure that had persisted for a few days and progressively weakening over the previous six months. Then, the patient was admitted to the intensive care unit with marked respiratory acidosis, respiratory failure and alterations in consciousness. At the follow-up, the patient was not diagnosed with a systematic disorder. Rather, the patient’s historical clinical findings suggested a metabolic disorder. Finally, the patient was diagnosed with biotinidase deficiency. Conclusion: Even though biotinidase deficiency is not frequently seen in the intensive care unit, metabolic syndromes such as biotinidase deficiency should be considered. Patients should be evaluated holistically with attention to medical history, family history and clinical findings. PMID:27761288

  2. UNITS OF MEASUREMENT: ORAL TRADITION, TRANSLATION STUDIES AND CORPUS LINGUISTICS

    Directory of Open Access Journals (Sweden)

    John ZEMKE

    2017-06-01

    Full Text Available The study of the world’s verbal arts offers an opportunity to consider ways that computational analysis and modeling of narratives may lead to new understandings of how they are constructed, their dynamics and relationships. Similarly, as corpus linguistics operations must define metrics, it offers an occasion to review basic interpretive concepts such as “units of analysis, context, and genre." My essay begins with an admittedly cursory overview from a novice perspective of what capabilities corpus linguistics currently possesses for the analysis and modeling of narratives. Consideration is given to the epistemological issue in the social sciences with the positivistic prescription or empiricist description of units of analysis and the potential pitfalls or advantages corpus linguistics encounters in searching for adequate equivalent terms. This review leads naturally to reflection on the crucial determinative action of context on meaning and the extent to which current computational interfaces are able to account for and integrate into global analysis of linguistic and performance dimensions such as performer, intonation, gesture, diction, idioms and figurative language, setting, audience, time, and occasion. As a tentative conclusion from this review, it can be stated that artificial intelligence for modeling narratives or devising narrative algorithms must develop capacities to account for performance dimensions in order to fulfill their analytical potential.

    Full Text Available Digoxin is used for heart failure associated to systolic dysfunction and high ventricular rate. It has a narrow therapeutic range and intoxication may occur due to drug interactions or comorbidities. The aim of this work was to study digoxin use in a public health unit delineating the profile of patients susceptible to digitalis intoxication. Medical records belonging to patients admitted to the cardiomyopathy ward of the health unit (2009-2010 and in use of digoxin were analyzed. Among 647 patients admitted, 185 individuals using digoxin and possessed records available. The registration of plasma digoxin concentration was found in 80 records and it was out of the therapeutic range in 42 patients (52.5%. This group of individuals was constituted mainly by males patients (79%, functional class III of heart failure (65%, exhibiting renal failure (33%. The evaluated sample reflects the epidemiology of heart failure in Brazil and, although pharmacotherapy had been according to Brazilian Guidelines, apparently the monitoring was not performed as recommended. This work highlighs the necessity of plasma digoxin constant monitoring during pharmacotherapy and the development of protocols that enable a safer use, especially in male patients, functional class III and with renal dysfunction.

    Full Text Available This paper discusses what the methods of conversation analysis (CA might have to offer the study of linguistic synonymy. It takes as a case study two items commonly held to be synonyms -'actually' and 'in fact'- and shows considerable differences between the two in their interactional implementation: they are implicated in the prosecution of differing courses of action. Such cases argue that it is analytically more profitable to consider what a lexical item does in the context of talk than what it means.

  8. Does United States v. Windsor (The DOMA Case Open the Door to Congressional Standing Rights?

    Directory of Open Access Journals (Sweden)

    Bradford C. Mank

    2015-06-01

    Full Text Available In rare cases, a president refuses to defend a statute based upon a belief that the statute is unconstitutional. The law is unclear whether either House of Congress has Article III standing to defend a statute that the president refuses to defend. In United States v. Windsor, the Supreme Court in 2013 addressed the onstitutionality of the Defense of Marriage Act (DOMA. The Obama Administration took the middle position of declining to defend DOMA, but still enforcing it, despite its view that the statute was unconstitutional to assist federal courts in reviewing the constitutionality of the statute. It was unclear whether an appeal was proper in the case once a district court held the statute was unconstitutional, and the Executive Branch essentially agreed with that decision. Applying both prudential standing principles and mandatory Article III standing rules, Justice Kennedy, writing for the majority, recognized that the Executive Branch was an appropriate party on appeal because it continued to enforce the statute. Additionally, the majority acknowledged that briefs filed by House of Representatives leadership supporting the constitutionality of DOMA supplied the necessary adverseness in the case given the Executive's view that DOMA was unconstitutional. The majority did not fully resolve the thorny issue of Congressional standing in cases where a president refuses to enforce a federal statute. Justice Scalia, in his dissent, emphasized the almost exclusive role of the Executive Branch in defending federal laws under Article II, squarely rejected Congressional standing, and argued that no party had standing to appeal in Windsor because the Executive agreed with the district court's judgment holding Section 3 unconstitutional. By contrast, Justice Alito, in his dissent, would have expressly recognized the authority and standing of the leaders of either House to defend any federal statute that the president does not defend. Yet by acknowledging

    2014-03-01

    The U.S. Geological Survey (USGS) resource assessment (Williams et al., 2008) outlined a mean 30 GWe of undiscovered hydrothermal resource in the western United States. One goal of the U.S. Department of Energy's (DOE) Geothermal Technology Office (GTO) is to accelerate the development of this undiscovered resource. DOE has focused efforts on helping industry identify hidden geothermal resources to increase geothermal capacity in the near term. Increased exploration activity will produce more prospects, more discoveries, and more readily developable resources. Detailed exploration case studies akin to those found in oil and gas (e.g. Beaumont and Foster, 1990-1992) will give developers central location for information gives models for identifying new geothermal areas, and guide efficient exploration and development of these areas. To support this effort, the National Renewable Energy Laboratory (NREL) has been working with GTO to develop a template for geothermal case studies on the Geothermal Gateway on OpenEI. In 2012, the template was developed and tested with two case studies: Raft River Geothermal Area (http://en.openei.org/wiki/Raft_River_Geothermal_Area) and Coso Geothermal Area (http://en.openei.org/wiki/Coso_Geothermal_Area). In 2013, ten additional case studies were completed, and Semantic MediaWiki features were developed to allow for more data and the direct citations of these data. These case studies are now in the process of external peer review. In 2014, NREL is working with universities and industry partners to populate additional case studies on OpenEI. The goal is to provide a large enough data set to start conducting analyses of exploration programs to identify correlations between successful exploration plans for areas with similar geologic occurrence models.

    The joint commission recognizes effective communication among caregivers as an important factor for ensuring patient safety, especially at times when the patient's care is handed off from one caregiver or service to another. This case study reviews the course of treatment for one patient throughout the perioperative continuum, including the postoperative unit where a pre-arrest situation developed. A workshop using Bloom's Taxonomy of Educational Objectives enabled staff members to more clearly understand the patient's situation. It also allowed the participants to gain an increased understanding of significant data and has been strategic in preventing patient complications.

    Necrotizing fasciitis represents a group of highly lethal infections characterized by rapidly progressing inflammation and necrosis. The aim of the study was to analyze the clinical profile, microbial flora, and predisposing risk factors in patients with necrotizing fasciitis. Lastly, we aimed to formulate a protocol for management of necrotizing fasciitis. Forty-eight cases of necrotizing fasciitis patients who reported to our hospital between April 2007 and September 2009 were included in the study. The commonest predisposing factors were age greater than 50 years (58 % cases) and diabetes mellitus (52 % cases). The commonest site involved was extremity (70.8 %). Majority of infections were polymicrobial (87.5 %). Repeated aggressive debridement was the commonest surgical procedure performed. Early and aggressive surgical debridement, often in multiple sittings, supplemented by appropriate antibiotics and supportive therapy, forms the key to a successful outcome in necrotizing fasciitis.

    Meningitis and/or encephalitis can pose a serious public health problem especially during outbreaks. A rapid and accurate diagnosis is important for effective earlier treatment. This study aimed to identify the possible microbial causes of meningitis and/or encephalitis cases. CSF and serum samples were collected from 322 patients who had signs and symptoms suggestive of meningitis and/or encephalitis. Out of 250 cases with confirmed clinical diagnosis, 83 (33.2%) were definitely diagnosed as bacterial meningitis and/or encephalitis cases (by using CSF culture, biochemical tests, latex agglutination test, and CSF stain), 17 (6.8%) were definitely diagnosed as having viral causes ( by viral isolation on tissue culture, PCR and ELISA), and one (0.4%) was diagnosed as fungal meningitis case (by India ink stain, culture, and biochemical tests). Also, there was one encephalitis case with positive serum ELISA IgM antibodies against Sandfly scilian virus. N. meningitidis, S. pneumonia and M. tuberculosis were the most frequently detected bacterial agents, while Enteroviruses, herpes simplex viruses and varicella zoster viruses were the most common viral agents encountered. Further studies are needed to assess the role of different microbial agents in CNS infections and their effective methods of diagnosis.

    2016-09-01

    Full Text Available BACKGROUND We have studied 200 patients of pleural fluid presenting to our tertiary care centre. Presence of cases of pleural fluid is a common presentation both in pulmonary and extrapulmonary diseases. We analysed the patients having both exudates and transudates and studied the results. MATERIALS AND METHODS We selected patients above 20 years of age and classified the patients with pleural fluid as having transudates and exudates. We studied the causes of transudates and exudates. A total of 200 patients are studied in this prospective study. Diagnosis of pleural exudates is made on the basis of Light’s criteria, chest x-ray, pleural fluid analysis, CT scan in selected patients, sputum examination, bronchoscopy and bronchial washings. Moribund and non-cooperative patients and HIV positives were excluded from the study. RESULTS Among the 200 patients, 91% have exudates. 9% have transudates by Light’s criteria. Tuberculosis is the commonest cause of effusions (64.83% followed by malignancy (13.73% and sympneumonic or parapneumonic effusions (9.89%. Pleural effusions occurred predominantly in males. Prevalence of diabetes Mellitus among cases of tuberculous pleural effusions is 13.56%. Tuberculous effusions are predominantly right-sided. CONCLUSION Predominant cases of pleural fluid are exudates. Commonest cause of pleural effusion is Tuberculosis followed by malignancy both pulmonary and extrapulmonary and sym. and parapneumonic effusions. Prevalence of Diabetes among Tuberculous pleural effusion cases is more or less same as in general population. Cough, expectoration fever, chest pain and breathlessness are the common symptoms occurring in three fourths of the patients of tuberculous pleural effusion. Most of the cases of Tuberculous effusion are above 30 years of age. In the diagnosis of tuberculous pleural effusion, Pleural fluid ADA is very important.

    To date, investigators have not demonstrated a clear relationship between a parent's history of prior perinatal losses and intensity of grief response following a subsequent perinatal loss. Examining this relationship for low-income, African-American parents is important because they are a vulnerable population due to the high incidence of perinatal mortality in Blacks and their other life stressors that can impact on grief response and caring needs. The purpose of this case study was to examine the impact of recurrent perinatal loss on a low-income African-American parent. The research design for this study was case report, using interview data collected from a mother who had recently experienced her fourth perinatal loss, which occurred at twenty-five weeks of gestation. Transcripts from two open-ended interviews were analyzed. The theoretical framework used to guide analysis of this case study was Lazarus and Folkman's stress and coping theory. Results demonstrated that the prior perinatal losses did not appear as critical components of the way the mother responded to her most recent loss. Instead, perception of the care she received from healthcare providers and how that care related to her experiences with her one living child who was born at the same gestational age was an important determinant in how she responded to her loss. The results of this case study demonstrate the importance assessing a person's perception of their experience and those factors which contribute to the way they respond.

  8. Nanomaterial Case Studies: Nanoscale Titanium Dioxide ...

    Science.gov (United States)

    This draft document presents two case studies of nanoscale titanium dioxide (nano-TiO2) used (1) to remove arsenic from drinking water and (2) as an active ingredient in topical sunscreen. The draft case studies are organized around a comprehensive environmental assessment approach that combines a product life cycle framework with the risk assessment paradigm. The document does not draw conclusions about potential risks. Rather, the case studies are intended to help identify what needs to be known in order to conduct a comprehensive environmental assessment of the potential risks related to nano-TiO2. This draft document is part of a process that will inform the development of EPA’s research strategy to support nanomaterial risk assessments. The complex properties of various nanomaterials make evaluating them in the abstract or with generalizations difficult if not impossible. Thus, this document focuses on two specific uses of nano-TiO2, as a drinking water treatment and as topical sunscreen. These case studies do not represent completed or even preliminary assessments; rather, they present the structure for identifying and prioritizing research needed to support future assessments.
