    The primary objective of this working group is to identify major technical, regulatory, and environmental issues that are relevant to the abandonment of offshore wellbores. Once the issues have been identified, the working group also has the objective of making recommendations or providing potential solutions for consideration. Areas for process improvement will be identified and {open_quotes}best practices{close_quotes} will be discussed and compared to {open_quotes}minimum standards.{close_quotes} The working group will primarily focus on wellbore abandonment in the Gulf of Mexico. However, workshop participants are encouraged to discuss international issues which may be relevant to wellbore abandonment practices in the Gulf of Mexico. The Abandoning Wells Group has identified several major areas for discussion that have concerns related to both operators and service companies performing wellbore abandonments in the Gulf of Mexico. The following broad topics were selected for the agenda: (1) MMS minimum requirements and state regulations. (2) Co-existence of best practices, new technology, and P & A economics. (3) Liability and environmental issues relating to wellbore abandonment.

    A preliminary study of the feasibility of using geophysical exploration methods to locate abandoned wells containing steel casing indicated that magnetic methods promise to be effective and that some electrical techniques might be useful as auxiliary methods. Ground magnetic measurements made in the vicinity of several known cased wells yielded total field anomalies with peak values ranging from about 1,500 to 6,000 gammas. The anomalies measured on the ground are very narrow and, considering noise due to other cultural and geologic sources, a line spacing on the order of 50 feet (15.2 m) would be necessary to locate all casings in the test area. The mathematical model used to represent a casing was a set of magnetic pole pairs. By use of a non-linear least squares curve fitting (inversion) program, model parameters which characterize each test casing were determined. The position and strength of the uppermost pole was usually well resolved. The parameters of lower poles were not as well resolved but it appears that the results are adequate for predicting the anomalies which would be observed at aircraft altitudes. Modeling based on the parameters determined from the ground data indicates that all of the test casings could be detected by airborne measurements made at heights of 150 to 200 feet (45.7-61.0 m) above the ground, provided lines spaced as closely as 330 feet (100 m) were used and provided noise due to other cultural and geologic sources is not very large. Given the noise levels of currently available equipment and assuming very low magnetic gradients due to geologic sources, the detection range for total field measurements is greater than that for measurements of the horizontal or vertical gradient of the total intensity. Electrical self-potential anomalies were found to be associated with most of the casings where measurements were made. However, the anomalies tend to be very narrow and, in several cases, they are comparable in magnitude to other small

    The history of hydrocarbon development in Louisiana and off its coast is one of the interdependence of technological innovation, entrepreneurial risk-taking, resource management, judicial decisions, legislation, marketing, employee good will, infrastructure and support services, coupled with favorable geologic structures that made early exploration and development relatively easy. Mariners sailing off the coast of Louisiana and Texas in the 1600`s recorded one of the earliest known natural oil seeps. They shrugged it off as unimportant, as there was no market for the substance they witnessed. The seepage, however, provided a tiny clue to the vast storehouse of hydrocarbons trapped in the earth`s crust extending from the uplands, through Louisiana`s swamps and marshes, and into the subaqueous habitats of the Gulf of Mexico-the world`s ninth largest body of water. In all cases, each move into a new geographic province required considerable change in operation philosophy and in the science supporting the exploration and development activity. As technology changed, or was developed to meet the industry`s needs, new frontiers were explored. However, with time-as is the case with any nonrenewable resource-fields and wells lost their productive life. They had to be abandoned. In fact, the Minerals Management Service suggests that within the next 10 years the offshore industry will remove 150 platforms per year, or nearly half of the current number of production units. The industry will be asked to dispose of nearly one unit every 2.4 days. If this is the case, abandonment issues are going to continue to surface.

    The artesian well tasked for abandonment was located on the LOX side (northwest area) of the launch complex. The exact date of well installation is unknown. The well was no longer in use at the time of the abandonment request, but was previously utilized under St. Johns River Water Management District (SJRWMD) consumptive use permit (No. 50054) for the Floridian Aquifer. The exact construction details of the LOX artesian well were also unknown; however, a similar-type artesian well was previously located on the LH2 side of the site, which was abandoned in 2012. Based on discussions with the NASA RPM and review of the LH2 artesian well abandonment completion report, the LH2 artesian well was reported to be an 8-inch diameter, 330-foot deep well. The NASA RPM communicated that the LOX artesian well was likely to be an 8-inch diameter, 380-foot deep well. This information was used for scoping, and was subsequently confirmed to be substantially accurate. No additional information could be found for the LOX artesian well using the NASA Remediation Information System (RIS).

    The objective of this study is to provide a new methodology for well abandonment. This practice is becoming more and more important because of the increasing number of production fields being abandoned. We strongly recommend a study of cement slurries properties for specific use in temporary and permanent abandonment plugs based on the estimation of the cement slurry hardened when placed in the well. By using specific additives, it is possible to achieve very stable slurries. For example, when permeability is reduced, formation fluid migration can be blocked and chemical reactions between the fluid and the slurry may be inhibited. With this objective, we present a laboratory investigation model and an example of slurry testing recommendation. During the abandonment operation, all records of the well characteristics should be maintained to include the reason for the abandonment, and location of fresh water, brine, and hydrocarbon zones that may exist. This documentation will also allow the analysis of solutions for the problems that originally caused the abandonment of the well. This data could be important for future use by environmental protection commissions to reopen or to drill an adjacent well. Given the high price of oil, it may now be economically feasible to reopen the well, if the reason for abandonment was low productivity. This way, a critical analysis of the current conditions of well and field abandonment in the country is presented. Based on this information, a review of the current standards is suggested. (author)

    More than three million abandoned oil and gas wells exist in the U.S., and information on many of these wells are lost. Recent measurements of 93 abandoned wells in Pennsylvania show that they may be a significant source of methane emissions to the atmosphere. Data such as depth and producing formation of 98% of these measured wells are unavailable. Information on the likely depth of the well and the formation, from which the well likely produced from, is important when evaluating the wells' potential to emit methane and/or to contaminate overlying aquifers, and when developing mitigation strategies. We use geospatial analysis that combines available public databases from the Pennsylvania Department of Environmental Protection and historic documents to determine the likely depth and formation from which the measured abandoned wells produced. We develop a framework to systematically evaluate the nearest well, pool, and field attributes and assign depth and producing formation to the measured wells based on how well these attributes match. We then use this information to perform a cost analysis for plugging based on well depth for Pennsylvania. The geospatial analysis framework presented here for determining abandoned well properties can be valuable for future field measurement designs, upscaling methane emissions, and mitigating abandoned wells in Pennsylvania but also the many other states with a long history of oil and gas production.

    The influence of the ventilation system on the abandoned gob weakens, so the gas seepage characteristics in the abandoned gob are significantly different from those in a normal mining gob. In connection with this, this study physically simulated the movement of overlying rock strata. A spatial distribution function for gob permeability was derived. A numerical model using FLUENT for abandoned gob methane drainage through surface wells was established, and the derived spatial distribution function for gob permeability was imported into the numerical model. The control range of surface wells, flow patterns and distribution rules for static pressure in the abandoned gob under different well locations were determined using the calculated results from the numerical model.

    An estimated 12 million wells have been drilled during the 150 years of oil and gas production in the United States. Many old oil and gas fields are now populated areas where the presence of improperly plugged wells may constitute a hazard to residents. Natural gas emissions from wells have forced people from their houses and businesses and have caused explosions that injured or killed people and destroyed property. To mitigate this hazard, wells must be located and properly plugged, a task made more difficult by the presence of houses, businesses, and associated utilities. This paper describes well finding methods conducted by the National Energy Technology Laboratory (NETL) that were effective at two small towns in Wyoming and in a suburb of Pittsburgh, Pennsylvania.

    The FY 2005 program was initiated on March 31, 2005, and concluded on July 16, 2005. The FY 2005 program initially included 25 wells requiring workover (P&A, Magenta reconfiguration, cleaning and keeping). During the process, the U.S. Bureau of Land Management (BLM) requested transfer of two wells (H-7c and H-8c) to their ownership for future livestock watering. These wells were transferred to the BLM through execution of Form wr-03, Declaration of Owner of Underground Water Rights, between the New Mexico Office of the State Engineer (NMOSE), the BLM, and the DOE Carlsbad Field Office (CBFO). One well (H-2b2) was cleaned and retained as a Culebra monitor well for continued use. One well (H-3d) was converted to a shallow well to monitor the formational contact between the Dewey Lake Redbeds Formation and the Santa Rosa Formation in support of the DP-831 discharge permit monitoring program. Nine dual-completion wells were reconfigured as Magenta-only monitor wells, and 12 wells were plugged and abandoned permanently. This report presents the summary in the same order that the wells were worked in the field.

    Full Text Available Abstract Background The care and protection of the estimated 143,000,000 orphaned and abandoned children (OAC worldwide is of great importance to global policy makers and child service providers in low and middle income countries (LMICs, yet little is known about rates of child labour among OAC, what child and caregiver characteristics predict child engagement in work and labour, or when such work infers with schooling. This study examines rates and correlates of child labour among OAC and associations of child labour with schooling in a cohort of OAC in 5 LMICs. Methods The Positive Outcomes for Orphans (POFO study employed a two-stage random sampling survey methodology to identify 1480 single and double orphans and children abandoned by both parents ages 6-12 living in family settings in five LMICs: Cambodia, Ethiopia, India, Kenya, and Tanzania. Regression models examined child and caregiver associations with: any work versus no work; and with working Results The majority of OAC (60.7% engaged in work during the past week, and of those who worked, 17.8% (10.5% of the total sample worked 28 or more hours. More than one-fifth (21.9%; 13% of the total sample met UNICEF's child labour definition. Female OAC and those in good health had increased odds of working. OAC living in rural areas, lower household wealth and caregivers not earning an income were associated with increased child labour. Child labour, but not working fewer than 28 hours per week, was associated with decreased school attendance. Conclusions One in seven OAC in this study were reported to be engaged in child labour. Policy makers and social service providers need to pay close attention to the demands being placed on female OAC, particularly in rural areas and poor households with limited income sources. Programs to promote OAC school attendance may need to focus on the needs of families as well as the OAC.

  20. Remediation of the Old Ecological Load in the Protected Area of the Morava River – Re-abandonment of the Oil and Gas Production Wells

    2015-06-01

    Full Text Available The presence of the former oil and gas producing wells that are or can be improperly abandoned creates a possible environmental hazard in terms of contamination of the groundwater and soil in the present. In the area of the Czech Republic, specifically in South Moravia part, which has a long oil and gas production history, plenty of such wells can be found. Finding out the information about their abandonment in archives is often very demanding (sometimes even impossible. During various survey works and re-abandonment attempts it was found out that many wells are originally abandoned improperly, insufficiently or not at all. The occurrence of such wells is not just potential but also very actual hazard for the cultural landscape of the South Moravia, especially for aquifers, agriculture and natural protected areas of national significance. This paper is focused on the possibility of the definitive abandonment of this particular ecological load. The proposed method was verified in laboratory conditions and in the field. It is now a standard form of the re abandonment of oil and gas wells without precise localization in the South Moravian oil fields.

    This report summarizes the well installation, plugging and abandonment, and redevelopment activities conducted during the federal fiscal year (FY) 1998 at the Y-12 Plant, Oak Ridge, Tennessee. Five new groundwater monitoring wells were installed at the Y-12 Plant under the FY 1998 drilling program. Two of the wells are located in west Bear Creek Valley, one is in the eastern Y-12 Plant area near Lake Reality, and two are located near the Oil Landfarm Waste Management Area, which were installed by Bechtel Jacobs Company LLC (Bechtel Jacobs) as part of a site characterization activity for the Oak Ridge Reservation (ORR) Disposal Cell. Also, two existing wells were upgraded and nine temporary piezometers were installed to characterize hydrogeologic conditions at the Disposal Cell site. In addition, 40 temporary piezometers were installed in the Boneyard/Bumyard area of Bear Creek Valley by Bechtel Jacobs as part of the accelerated remedial actions conducted by the Environmental Restoration Program. Ten monitoring wells at the Y-12 Plant were decommissioned in FY 1998. Two existing monitoring wells were redeveloped during FY 1998 (of these, GW-732 was redeveloped tsvice). All well installation and development (including redevelopment) was conducted following industry-standard methods and approved procedures from the Environmental Surveillance Procedures Quality Control Program (Energy Systems 1988); the Resource Conservation and Recovery Act (RCRA) Groundwater Monitoring Technical Enforcement Guidance Document (EPA 1992); and the Monitoring Well Installation Plan for the Department of Energy Y-12 Plant, Oak Ridge, Tennessee (Energy Systems 1997a).

    The aim of this study was to consider the potential legacy of increased onshore, unconventional gas production by examining the integrity of decommissioned, onshore, oil and gas wells in the UK. In the absence of a history of unconventional hydrocarbon exploitation in the UK, conventional onshore sites were considered and an examination of pollution incidents records had suggested that only a small fraction of onshore wells could show integrity failures. In this study the fugitive emissions of methane from former oil and gas production wells onshore in the UK were considered as a measure of well integrity. The survey considered 49 decommissioned (abandoned) wells from 4 different basins that were between 8 and 78 years old; all but one of these wells would be considered as having been decommissioned properly, i.e. wells cut, sealed and buried by soil cover to the extent that the well sites were being used for agriculture. For each well site the soil gas methane was analysed multiple times and assessed relative to a nearby control site of similar land-use and soil type. The results will be expressed in terms of the proportion and extent of well integrity failure, or success, over time since decommissioning and relative to local control sites. The probability of failure and the emissions factor for decommissioned wells will be presented.

    Plugging and abandonment (P&A) of defunct groundwater monitoring wells is a primary element of the Oak Ridge Y-12 Plant Groundwater Protection Program (GWPP) (AJA Technical Services, Inc. 1996). This document is the revised groundwater monitoring well P&A plan for the U.S. Department of Energy (DOE) Y-12 Plant located in Oak Ridge, Tennessee. This plan describes the systematic approach employed by Y-12 Plant GWPP to identify wells that require P&A, the technical methods employed to perform P&A activities, and administrative requirements. Original documentation for Y-12 Plant GWPP groundwater monitoring well P&A was provided in HSW, Inc. (1991). The original revision of the plan specified that a comprehensive monitoring well P&A was provided in HSW, Inc. (1991). The original revision of the plan specified that a comprehensive monitoring well P&A schedule be maintained. Wells are added to this list by issuance of both a P&A request and a P&A addendum to the schedule. The current Updated Subsurface Data Base includes a single mechanism to track the status of monitoring wells. In addition, rapid growth of the groundwater monitoring network and new regulatory requirements have resulted in constant changes to the status of wells. As a result, a streamlined mechanism to identify and track monitoring wells scheduled for P&A has been developed and the plan revised to formalize the new business practices.

    Abandoned oil and gas (AOG) wells can provide pathways for subsurface fluid migration, which can lead to groundwater contamination and gas emissions to the atmosphere. Little is known about the millions of AOG wells in the U.S. and abroad. Recently, we acquired data on methane emissions from 42 plugged and unplugged AOG wells in five different counties across western Pennsylvania. We used historical documents to estimate well depths and used these depths with the emissions data to estimate the wells' effective permeabilities, which capture the combined effects of all leakage pathways within and around the wellbores. We find effective permeabilities to range from 10(-6) to 10(2) millidarcies, which are within the range of previous estimates. The effective permeability data presented here provide perspective on older AOG wells and are valuable when considering the leakage potential of AOG wells in a wide range of applications, including geologic storage of carbon dioxide, natural gas storage, and oil and gas development.

    A major question in philosophy of science involves the unreasonable effectiveness of mathematics in physics. Why should mathematics, created or discovered, with nothing empirical in mind be so perfectly suited to describe the laws of the physical universe? We review the well-known fact that the symmetries of the laws of physics are their defining properties. We show that there are similar symmetries of mathematical facts and that these symmetries are the defining properties of mathematics. By examining the symmetries of physics and mathematics, we show that the effectiveness is actually quite reasonable. In essence, we show that the regularities of physics are a subset of the regularities of mathematics.

    Research has clearly shown the relationship between subjective well-being and work performance, even though there is debate over the causality of that relationship (i.e., does subjective well-being cause higher work performance or does greater work performance lead to subjective well-being?). Regardless, researchers and practitioners would agree…

    For a variety of reasons, thousands of oil and gas wells have been abandoned in the Gulf Coast Region of the United States. Many of these wells penetrated geopressured zones whose resource potential for power generation was undervalued or ignored. The U.S. Department of Energy (DOE) Geopressured-Geothermal Research Program was chartered to improve geothermal technology to the point where electricity could be commercially produced from a substantial number of geopressured resource sites. This research program focused on relatively narrow technical issues that are unique to geopressured resources such as the ability to predict reservoir production capacity based on preliminary flow tests. Three well sites were selected for the research program. These are the Willis Hulin and Gladys McCall sites in Louisiana, and the Pleasant Bayou site in Texas. The final phase of this research project consists of plug and abandonment (P&A) of the wells and site restoration.

    In August 2004, the corporative databank of the Brazilian Petroleum Agency included the records of 21,508 wells drilled in the country, of which 17,621 onshore. Evaluation of the suitability of well abandonment and decommissioning procedures in areas explored by the oil industry, particularly those lacking the legal protection by contracts signed with the Agency, has demanded the definition of priorities compatible with the limited human and financial resources. Excluding the wells covered by concession contracts in exploration blocks and production fields, 1,127 onshore wells still remained in the priority's list, of which 730 drilled from the 1920's through the 70's, 207 during the 80's, and 90 in the past decade until August 1998. In regard to the oldest 730 wells, all drilled in a period when environmental concerns were still irrelevant, and abandonment and decommissioning most likely inadequate, geo processing resources have been used to select the priority-determining criteria for evaluation of the various well groups. This work presents the methodology followed in the selection of the most critical cases. (author)

    Unplugged abandoned oil and gas wells in the Appalachian region can serve as conduits for the movement of waters impacted by fossil fuel extraction. Strontium isotope and geochemical analysis indicate that artesian discharges of water with high total dissolved solids (TDS) from a series of gas wells in western Pennsylvania result from the infiltration of acidic, low Fe (Fe < 10 mg/L) coal mine drainage (AMD) into shallow, siderite (iron carbonate)-cemented sandstone aquifers. The acidity from the AMD promotes dissolution of the carbonate, and metal- and sulfate-contaminated waters rise to the surface through compromised abandoned gas well casings. Strontium isotope mixing models suggest that neither upward migration of oil and gas brines from Devonian reservoirs associated with the wells nor dissolution of abundant nodular siderite present in the mine spoil through which recharge water percolates contribute significantly to the artesian gas well discharges. Natural Sr isotope composition can be a sensitive tool in the characterization of complex groundwater interactions and can be used to distinguish between inputs from deep and shallow contamination sources, as well as between groundwater and mineralogically similar but stratigraphically distinct rock units. This is of particular relevance to regions such as the Appalachian Basin, where a legacy of coal, oil and gas exploration is coupled with ongoing and future natural gas drilling into deep reservoirs.

  15. Hydro-mechanical simulations of well abandonment at the Ketzin pilot site for CO2 storage verify wellbore system integrity

    2015-04-01

    In geological underground utilisation, operating and abandoned wells have been identified as a main potential leakage pathways for reservoir fluids. In the scope of the well abandonment procedure currently carried out at the Ketzin pilot site for CO2 storage in Germany, a hydro-mechanical model was built to carry out a coupled analysis of the integrity in the entire wellbore system. The main aim of the present study was to assess the impacts of stress changes associated with CO2 injection as well as the cement backfill undertaken in the scope of well abandonment. A numerical model comprising cement sheaths, steel casings, tubing, multiple packers and wellbore annuli was implemented to enable a detailed representation of the entire wellbore system. The numerical model grid has a horizontal discretisation of 5 m x 5 m to focus on near wellbore effects, whereby element sizes increase with increasing distance from the wellbore. Vertical grid discretisation uses a tartan grid type over the entire model thickness of 1,500 m to ensure a sufficient discretisation of all wellbore system elements as well as of the reservoir unit. The total number of elements amounts to 210,672. Mechanical model parameters were taken from geological, drilling, logging and laboratory test data based on Ketzin pilot site-specific information as well as related literature (Kempka et al., 2014). The coupled calculations were performed using an elasto-plastic constitutive law, whereby an initial simulation run ensured a static mechanical equilibrium to represent the initial state before the start of CO2 injection. Thereto, gravitational load of the overburden rocks and pore pressure distribution following available well logs were integrated for initial model parameterisation including a normal faulting stress regime defined by a horizontal to vertical total stress ratio of 0.85. A correction accounting for the temperature and pressure dependent CO2 density was carried out in advance of each

    Full Text Available This study aimed to investigate the different dimensions of well-being (namely, work engagement, job satisfaction, and psychological stress and possible predictors such as personality and perceived organizational support. A cross-sectional survey design was used, with a sample of 490 ambulance personnel in the United Kingdom. Significant correlations were found between the dimensions of job satisfaction, engagement, and stress. The results also supported a hierarchical model with job satisfaction, stress, and engagement loading onto one higher order factor of work well-being. Emotional stability and perceived organizational support were identified as significant predictors of well-being. The findings suggest the importance of measuring the work-related well-being of ambulance personnel holistically and present perceived organizational support as a possible area for interventions to improve well-being.

    Abandoned coal mine groundwater frequently contains depressed pH levels and elevated levels of hydrogen sulphide, iron, aluminium and nitrates. Abandoned coal mine groundwater is also usually high in copper, zinc, mercury, and lead. Groundwater from abandoned mines can seriously affect public health through the discharge of non-point source pollution. This paper presents information on a research project regarding the possible impacts of abandoned coal mines and its effects on groundwater as it relates to the health of residents in South Wellington, Nanaimo, British Columbia. The purpose of the project is to determine which illnesses are more common in South Wellington, Nanaimo and in the control area. The paper provides a discussion of the Nanaimo coal field and three major seams; the Wellington, Newcastle and Douglas which are most likely to have a significant impact on groundwater in South Wellington. 27 refs.

    Christenson, Scott C.

    1995-01-01

    The Roubidoux aquifer in Ottawa County Oklahoma is used extensively as a source of water for public supplies, commerce, industry, and rural water districts. Water in the Roubidoux aquifer in eastern Ottawa County has relatively low dissolved-solids concentrations (less than 200 mg/L) with calcium, magnesium, and bicarbonate as the major ions. The Boone Formation is stratigraphically above the Roubidoux aquifer and is the host rock for zinc and lead sulfide ores, with the richest deposits located in the vicinity of the City of Picher. Mining in what became known as the Picher mining district began in the early 1900's and continued until about 1970. The water in the abandoned zinc and lead mines contains high concentrations of calcium, magnesium, bicarbonate, sulfate, fluoride, cadmium, copper, iron, lead, manganese, nickel, and zinc. Water from the abandoned mines is a potential source of contamination to the Roubidoux aquifer and to wells completed in the Roubidoux aquifer. Water samples were collected from wells completed in the Roubidoux aquifer in the Picher mining district and from wells outside the mining district to determine if 10 public supply wells in the mining district are contaminated. The chemical analyses indicate that at least 7 of the 10 public supply wells in the Picher mining district are contaminated by mine water. Application of the Mann-Whitney test indicated that the concentrations of some chemical constituents that are indicators of mine-water contamination are different in water samples from wells in the mining area as compared to wells outside the mining area. Application of the Wilcoxon signed-rank test showed that the concentrations of some chemical constituents that are indicators of mine-water contamination were higher in current (1992-93) data than in historic (1981-83) data, except for pH, which was lower in current than in historic data. pH and sulfate, alkalinity, bicarbonate, magnesium, iron, and tritium concentrations consistently

    Full Text Available This paper is the result of a research related to the school culture studies. The school culture is an important theoretical key for the internal comprehension of the day-to-day of the school, by focusing on the interaction of the school´s actors. Our goal was to comprehend the functionalism of the abandonment of teaching in Physical Education (PE for the school culture. It was an ethnomethodological research and carried out in a school situated in Curitiba – PR, using field diary and biographical interview as instruments for data collection. We observed two classes of PE, one of the 4th and another of the 5th school year. We concluded that the abandonment of teaching in PE is functional to the school culture, being supported by other actors of the school day living.

    2009-06-01

    The author describes briefly some experiences of his sense of non-existence as an analyst in relation to five patients. He considers the possible countertransference significance of these experiences and puts forward a hypothesis that his sense of non-existence as an analyst might be a clue to regression in the patient to the anxieties of a baby without a mother, even though other clinical evidence of regression might be lacking. Referring back to Jung's early formulation of transference and countertransference as aspects of the unconscious identity shared between analyst and patient, he further develops his hypothesis, suggesting that, in the cases he has presented, analyst and patient were relating through shared dynamic roots in the archetype of the abandoned child. He briefly demonstrates how the understanding thus achieved was of clinical use in the analyses of the patients he has presented.

    2010-07-01

    Previous coal mining activities in Sydney, Nova Scotia (NS) have included the creation of shallow, unrecorded underground coal extraction sites known as bootleg pits. The sites are a public safety hazard and can also impact groundwater flow. This paper presented an outline of the remediation strategies used to mitigate the hazards associated with the bootleg pits as part of a mine site closure and reclamation program currently being completed by the Cape Breton Corporation (ECBC). The strategies included the use of sinkhole subsidence hazard maps. Long-term visual monitoring is also being used in areas associated with sinkhole development. Larger abandoned areas have been cleared, backfilled and re-graded while including provisions for the ongoing drainage of mine waters. Gas monitoring and safety procedures were also reviewed. 2 refs., 4 figs.

    After successfully locating one abandoned brine well by an electromagnetic method during testing in 2001 and five abandoned brine wells by a high-resolution magnetic method during 2002, a high-resolution magnetic method was again proposed to search for wells in 2003 when a second sensor was employed to acquire data for calculating the pseudo-vertical gradient of magnetic fields. Total area surveyed in 2003 was 1,024,000 ft2, which was divided into grids with an average size of 10,000 ft2 and distributed across eight different sites. Magnetic anomalies and their vertical gradients from known brine wells were first recorded as signatures to identify anomalies caused by possible buried brine wells. Of fifty-one verified anomalies, thirtyone anomalies were due to wells buried at depths from 0 to 8.5 ft: twenty-one 6- to 9-inch abandoned brine wells, seven 1.5- to 3-inch probable water wells, one 16-inch dewatering well for a construction site at a depth of 3 ft, and two 4-inch wells on the ground surface. Approximate monopole shaped anomalies were observed from all these wells after data corrections. However, the range of amplitudes of magnetic anomalies from 7,000 to 28,000 nT from these abandoned brine wells was measured. This range of anomalies is mainly due to the thickness and depth of buried wells. Anomaly amplitudes from 1.5- to 3-inch wells are 4,000 to 8,000 nT and linearly correlate with the buried depth. One 3-inch well that caused an anomaly of 13,000 nT could be the inner pipe of a brine well. Gradient anomalies are roughly in a range of 100 to 200 nT/inch for 1.5-to 3-inch wells and 200 to 300 nT/inch for brine wells.As indicated by the potential-field theory, gradient data possess higher horizontal resolution than the magnetic field itself. Gradient data provide valuable assistance in determining horizontal locations of anomaly sources for excavation. In practice, however, improvement in the horizontal resolution is limited by surveyline spacing. If only

  6. What Works and What Does Not: A Discussion of Popular Approaches for the Abandonment of Female Genital Mutilation

    Directory of Open Access Journals (Sweden)

    R. Elise B. Johansen

    2013-01-01

    Full Text Available The prevalence of Female Genital Mutilation (FGM is reducing in almost all countries in which it is a traditional practice. There are huge variations between countries and communities though, ranging from no change at all to countries and communities where the practice has been more than halved from one generation to the next. Various interventions implemented over the last 30–40 years are believed to have been instrumental in stimulating this reduction, even though in most cases the decrease in prevalence has been slow. This raises questions about the efficacy of interventions to eliminate FGM and an urgent need to channel the limited resources available, where it can make the most difference in the abandonment of FGM. This paper is intended to contribute to the design of more effective interventions by assessing existing knowledge of what works and what does not and discusses some of the most common approaches that have been evaluated: health risk approaches, conversion of excisers, training of health professionals as change agents, alternative rituals, community-led approaches, public statements, and legal measures.

  7. Well-being at work--overview and perspective.

    Schulte, Paul; Vainio, Harri

    2010-09-01

    This paper provides an overview of and perspective on the concept of well-being at work. Well-being is a term that reflects not only on one's health but satisfaction with work and life. Well-being is a summative concept that characterizes the quality of working lives, including occupational safety and health (OSH) aspects, and it may be a major determinant of productivity at the individual, enterprise and societal levels. Based on a review of the literature and a recent conference, we suggest a model linking workforce well-being, productivity, and population well-being. To appraise the validity of the model, we consider five questions: (i) is there a robust and usable definition of workplace well-being? (ii) have the variables that influence well-being been aptly described and can they be measured and used in risk assessments? (iii) what is the nature of evidence that well-being is linked to productivity? (iv) what is the state of knowledge on the effectiveness of interventions to promote workplace well-being? and (v) should interventions aimed at improving well-being at work focus on more than work-related factors?

    Previous research on authenticity has mainly focused on trait conceptualizations of authenticity (e.g., Wood et al., 2008), whereas in specific environments (e.g., at work) state conceptualizations of authenticity (cf. Van den Bosch & Taris, 2013) are at least as relevant. For example, working conditions are subject to change, and this could well have consequences for employees' perceived level of authenticity at work. The current study employs a work-specific, state-like conceptualization of authenticity to investigate the relations between authenticity at work, well-being, and work outcomes. A series of ten separate hierarchical regression analyses using data from 685 participants indicated that after controlling for selected work characteristics and demographic variables, authenticity at work accounted for on average 11% of the variance of various wellbeing and work outcomes. Of the three subscales of authenticity at work (i.e., authentic living, self-alienation, and accepting influence), self-alienation was the strongest predictor of outcomes, followed by authentic living and accepting external influence, respectively. These findings are discussed in the light of their practical and theoretical implications.

    The services in charge of managing the CERN site have recently noted an increase in the number of abandoned vehicles. This poses a risk from the point of view of safety and security and, on the eve of several important events in honour of CERN's fiftieth anniversary, is detrimental to the Organization's image. Owners of vehicles that have been left immobile for some time on the CERN site, including on the external car park by the flags, are therefore invited to contact the Reception and Access Control Service (service-parking-longterm@cern.ch) before 1st October 2004 and, where appropriate, move their vehicle to a designated long-term parking area. After this date, any vehicle whose owner has failed to respond to this request and which is without a number plate, has been stationary for several weeks or is out of service, may be impounded at the owner's risk and expense.

    2015-03-01

    Well-being or quality of life is thought to give a more accurate picture of the impact a condition has on day-to-day functioning than traditional outcome measures. This study sought to examine the relationship between engagement in play and well-being for preschool children with and without developmental coordination disorder (DCD). A quasi-experimental design was used with two independent groups of preschool children aged 4-6 years with (n=32) and without (n=31) probable DCD. Play skills were assessed using the Play Observation Scale based on 30min of videotape of free-play at preschool. Well-being was assessed using a parent-proxy version of the Revised Children Quality of Life Questionnaire (KINDL(R)). Spearman rho correlations were performed to examine the relationship between play and well-being. Well-being at preschool was significantly lower for the children in the DCD group however overall well-being was not significantly different. Engagement in type of social play (solitary, parallel or group) was found to predict well-being for the typically developing children. For the children with DCD, engagement in group play was not associated with well-being. An explanation for this difference may be that children with DCD may not experience free-play at preschool as "play" but rather as hard work. Further research is needed to determine why children with DCD experience lower well-being at preschool than their peers and to investigate children's perceptions of free-play. This may enable teachers and therapists to better support children with DCD in the preschool environment.

    The aim was to examine whether work engagement and work commitment can be empirically discriminated and how they are associated with well-being. The terminology used in literature and in practice is confused by the interchangeable use of these terms. Only few studies, like Hallberg and Schaufeli's study, have examined the relationships between work engagement and work commitment systematically by using empirical data. In this study, the data were gathered via self-reported questionnaire from the healthcare staff working in 14 health centres and four hospitals in Finland. The data consisted of 435 responses. The material was analysed by using structural equation modelling (SEM) and correlations. The items of work engagement and work commitment dimensions (identification with organization, willingness to exert in organization's favour, occupational commitment and job involvement) loaded on their own latent variables in SEM analysis, so the data supported this five-factor model. Work engagement and work commitment dimensions were positively related, sharing between 2 and 33% of their variances. These constructs also displayed different correlations with some indicators of well-being measured as personal accomplishment, psychological well-being, mental resources, internal work motivation and willingness to stay on at work. Work engagement had moderate positive correlation to personal accomplishment (r = 0.68, p work engagement can be empirically discriminated from work commitment. They are distinct, yet related constructs that complement each other, describing different aspects of positive attitudes towards work. The results can be utilized in interventions aimed at quality of working life in health care as well as in studies investigating discriminant and construct validity.

    This report describes work done to characterize by chemical methods the temperature/ time degradation behavior of polymer based fluids that may be used in stimulating geothermal wells by fracturing. The polymers tested were hydroxypropulguar (HP guar), hydroxethylcellulose (HEC), carboxymethylcellulose (CMC), and XC Polymer. Also two commercially available cross-linked HP guar systems were tested. The report covers the development of analytical techniques for characterizing the polymers and the results of static and dynamic high temperature aging of the polymers in various salt water environments. The fluids were tested at 150, 200, and 250{degree}C. The report covers the implications of these results based on the time/ temperature degradation of the polymers and the relative ease of removing the degraded polymer from a sandpack. [DJE-2005

    Full Text Available Abstract Background Insufficient PA has been shown to cluster with other CVD risk factors including insufficient fruit and vegetable intake, overweight, increased serum cholesterol concentrations and elevated blood pressure. This paper describes the development of Working on Wellness (WOW, a worksite intervention program incorporating motivational interviewing by wellness specialists, targeting employees at risk. In addition, we describe the evaluation the effectiveness of the intervention among employees at increased risk for cardiovascular disease. Methods The intervention mapping (IM protocol was used in the planning and design of WOW. Focus group discussions and interviews with employees and managers identified the importance of addressing risk factors for CVD at the worksite. Based on the employees’ preference for individual counselling, and previous evidence of the effectiveness of this approach in the worksite setting, we decided to use motivational interviewing as part of the intervention strategy. Thus, as a cluster-randomised, controlled control trial, employees at increased risk for CVD (N = 928 will be assigned to a control or an intervention group, based on company random allocation. The sessions will include motivational interviewing techniques, comprised of two face-to-face and four telephonic sessions, with the primary aim to increase habitual levels of PA. Measures will take place at baseline, 6 and 12 months. Secondary outcomes include changes in nutritional habits, serum cholesterol and glucose concentrations, blood pressure and BMI. In addition, healthcare expenditure and absenteeism will be measured for the economic evaluation. Analysis of variance will be performed to determine whether there were significant changes in physical activity habits in the intervention and control groups at 6 and 12 months. Discussion The formative work on which this intervention is based suggests that the strategy of targeting

    This paper contrasts the offshore scene of 30 years ago with today, within the limits of inadequate monitoring, then and now. It identifies stress, bullying, change, long working hours and offshore trips and lifestyle as major factors that now have to be addressed if the health of the ageing work force is not to be compromised. Activity external to formal working hours such as travel to and from home and domestic and social relationships are all modified by the nature of offshore work but rarely acknowledged as the responsibility of the employer or operator. The development of a superior lifelong health tracking system is essential for long-term surveillance and epidemiological studies. The acceptance by operators of their long-term responsibilities for staff and the families of offshore workers needs to be better developed. (author)

    Employee stress is a significant issue in the hospitality industry, and it is costly for employers and employees alike. Although addressing and reducing stress is both a noble goal and is capable of resulting in expense reductions for employers, the nature and quantity of hospitality employee stress is not fully understood. The first aim of this study was to identify common work stressors in a sample of 164 managerial and hourly workers employed at 65 different hotels who were each interviewed for eight consecutive days. The two most common stressors were interpersonal tensions at work and overloads (e.g., technology not functioning). The second aim was to determine whether there were differences in the types and frequency of work stressors by job type (i.e., managers v. non-managers), gender, and marital status. Hotel managers reported significantly more stressors than hourly employees. There were no significant differences by gender or marital status. The third aim was to investigate whether the various stressors were linked to hotel employee health and work outcomes. More employee and coworker stressors were linked to more negative physical health symptoms. Also, interpersonal tensions at work were linked to lower job satisfaction and greater turnover intentions.

    Underground pumped storage hydroelectricity (UPSH) plants using open-pit or deep mines can be used in flat regions to store the excess of electricity produced during low-demand energy periods. It is essential to consider the interaction between UPSH plants and the surrounding geological media. There has been little work on the assessment of associated groundwater flow impacts. The impacts on groundwater flow are determined numerically using a simplified numerical model which is assumed to be representative of open-pit and deep mines. The main impact consists of oscillation of the piezometric head, and its magnitude depends on the characteristics of the aquifer/geological medium, the mine and the pumping and injection intervals. If an average piezometric head is considered, it drops at early times after the start of the UPSH plant activity and then recovers progressively. The most favorable hydrogeological conditions to minimize impacts are evaluated by comparing several scenarios. The impact magnitude will be lower in geological media with low hydraulic diffusivity; however, the parameter that plays the more important role is the volume of water stored in the mine. Its variation modifies considerably the groundwater flow impacts. Finally, the problem is studied analytically and some solutions are proposed to approximate the impacts, allowing a quick screening of favorable locations for future UPSH plants.

  6. Abandoned Texas oil fields

    1980-12-01

    Data for Texas abandoned oil fields were primarily derived from two sources: (1) Texas Railroad Commission (TRRC), and (2) Dwight's ENERGYDATA. For purposes of this report, abandoned oil fields are defined as those fields that had no production during 1977. The TRRC OILMASTER computer tapes were used to identify these abandoned oil fields. The tapes also provided data on formation depth, gravity of oil production, location (both district and county), discovery date, and the cumulative production of the field since its discovery. In all, the computer tapes identified 9211 abandoned fields, most of which had less than 250,000 barrel cumulative production. This report focuses on the 676 abandoned onshore Texas oil fields that had cumulative production of over 250,000 barrels. The Dwight's ENERGYDATA computer tapes provided production histories for approximately two-thirds of the larger fields abandoned in 1966 and thereafter. Fields which ceased production prior to 1966 will show no production history nor abandonment date in this report. The Department of Energy hopes the general availability of these data will catalyze the private sector recovery of this unproduced resource.

    2016-01-01

    Based on a lifespan perspective on work design, person-environment interaction and fit theories, models of successful aging at work, and role theory, we review research on the role of worker age in relationships between work characteristics and occupational well-being. We first focus on interaction effects of work characteristics and age on occupational well-being. Research has found that age can moderate associations between work characteristics and occupational well-being indicators, and that work characteristics can moderate associations between age and occupational well-being indicators. Next, we describe research showing that work characteristics can mediate associations between age and occupational well-being indicators. The relationships of age with specific work characteristics and occupational well-being indicators can be linear or non-linear. We conclude our literature review by discussing implications for future research. PMID:27713711

    Full Text Available OBJECTIVE To assess the determinants of exclusive breastfeeding abandonment. METHODS Longitudinal study based on a birth cohort in Viçosa, MG, Southeastern Brazil. In 2011/2012, 168 new mothers accessing the public health network were followed. Three interviews, at 30, 60, and 120 days postpartum, with the new mothers were conducted. Exclusive breastfeeding abandonment was analyzed in the first, second, and fourth months after childbirth. The Edinburgh Postnatal Depression Scale was applied to identify depressive symptoms in the first and second meetings, with a score of ≥ 12 considered as the cutoff point. Socioeconomic, demographic, and obstetric variables were investigated, along with emotional conditions and the new mothers’ social network during pregnancy and the postpartum period. RESULTS The prevalence of exclusive breastfeeding abandonment at 30, 60, and 120 days postpartum was 53.6% (n = 90, 47.6% (n = 80, and 69.6% (n = 117, respectively, and its incidence in the fourth month compared with the first was 48.7%. Depressive symptoms and traumatic delivery were associated with exclusive breastfeeding abandonment in the second month after childbirth. In the fourth month, the following variables were significant: lower maternal education levels, lack of homeownership, returning to work, not receiving guidance on breastfeeding in the postpartum period, mother’s negative reaction to the news of pregnancy, and not receiving assistance from their partners for infant care. CONCLUSIONS Psychosocial and sociodemographic factors were strong predictors of early exclusive breastfeeding abandonment. Therefore, it is necessary to identify and provide early treatment to nursing mothers with depressive symptoms, decreasing the associated morbidity and promoting greater duration of exclusive breastfeeding. Support from health professionals, as well as that received at home and at work, can assist in this process.

    2011-12-01

    This article investigates a change in the structuring of work time, using a natural experiment to test whether participation in a corporate initiative (Results Only Work Environment; ROWE) predicts corresponding changes in health-related outcomes. Drawing on job strain and stress process models, we theorize greater schedule control and reduced work-family conflict as key mechanisms linking this initiative with health outcomes. Longitudinal survey data from 659 employees at a corporate headquarters shows that ROWE predicts changes in health-related behaviors, including almost an extra hour of sleep on work nights. Increasing employees' schedule control and reducing their work-family conflict are key mechanisms linking the ROWE innovation with changes in employees' health behaviors; they also predict changes in well-being measures, providing indirect links between ROWE and well-being. This study demonstrates that organizational changes in the structuring of time can promote employee wellness, particularly in terms of prevention behaviors.

    Well-being at work is based on Positive Psychology, and is defined as a psychological state with positive affective links towards work and also towards the organisation. The purpose of this study was to look at the degree of well-being at work among nursing professionals who work at a University hospital and also identify differences between occupational categories and types of work contracts. The sample was made up of 340 professionals who answered valid scales of the following constructs: Work Satisfaction, Involvement with Work and Affective Organisational Commitment. For the analysis of the data we used SPSS, version 12, for descriptive statistics, and also for testing differences between means. The results showed an average level of well-being in the workplace and also differences between professional categories and work regime, when it comes to satisfaction with salaries and promotions, which can have a reflection in the quality of service provided to the patients of this University hospital.

    Full Text Available We present a social work study on relationship between parenting styles and career aspirations as well as psychological well-being among third year high school female students in city of Khomeinishahr, Iran during the year of 2012. The study selects a sample of 300 students from 1260 female students who were enrolled in third year high school education, randomly. The study uses the Baumrind’s questionnaire on parenting style, which consists of 30 questions which equally measure three parenting styles including authoritarian, indulgent and authoritative in Likert scale. The survey also uses Gottfredson’s questionnaire to examine occupational aspirations. The study examines whether there is any relationship between parenting style from one side and three personal characteristics including gender, career aspiration and wishes type on the other side. Using Chi-Square technique, the survey examines three hypotheses and the results confirm all three hypotheses of the survey.

    Full Text Available Integrating theories of adult attachment and well-being at the workplace, the present study tested the role of attachment style in predicting work-related well-being in terms of job satisfaction and job involvement, over and above dispositional trait measures (emotional traits and work-related traits. A sample of workers took part in a correlational study that explored the relationships among a adult attachment, b emotional traits, c work-related traits, and d work-related well-being indices. The results showed that both secure and anxious attachment style explained workers’ job involvement, whereas the secure and avoidant attachment styles explained workers’ job satisfaction. The current findings thus confirm and expand the literature's emphasis on studying the variables and processes that underlie people's mental health in the work setting, and have implications for assessing and promoting well-being in the workplace.

    Full Text Available Early childhood education teachers’ happiness at work reflects in children. Finnish day care system has faced plenty of changes and they can also reflect in well-being at day care. The aim of this article to dissect the state of well-being and thriving at work in Finnish day care centers from early childhood education teachers’ point of view and to discuss how well-being could be promoted. The data comprises group interviews (N=9 collected with memory-work method among North-Finnish early childhood education teachers (N=4. The results revealed that several factors were reported as threatening early childhood education teachers’ well-being. These kinds of factors were, among others, increasing amount of administrative tasks as well as concern about their educational task becoming narrower, the sufficiency of one’s own resources, and how the economic measures for efficiency have started to extend to day care as well. Perceived well-being increases when early childhood education teachers have time to encounter an individual child and concentrate on their basic work, rearing and teaching children. Based on the findings, suggestions how to enhance early childhood education teachers’ well-being are discussed. Promotion of well-being necessitates development actions both at the level of society, day care system and early childhood education teachers’ personal level. In this article, we highlight how organizational structures enhance or hinder well-being.

    2016-01-01

    Despite research advances, work-family scholars still lack an understanding of how leadership constructs relate to an employee's ability to effectively manage the work-family interface. In addition, there remains a need to examine the process through which leadership and work-family conflict influence well-being outcomes. Using a sample of 312 workers, a mediated process model grounded in social exchange theory is tested wherein the authors seek to explain how leaders shape employee perceptions, which, in turn, impact organizational fulfillment of expectations (i.e., psychological contract breach), work-family conflict, and well-being. A fully latent structural equation model was used to test study hypotheses, all of which were supported. Building on existing theory, findings suggest that the supervisor plays a critical role as a frontline representative for the organization and that work-family conflict is reduced and well-being enhanced through a process of social exchange between the supervisor and worker.

    2006-01-01

    Flexible working hours can have several meanings and can be arranged in a number of ways to suit the worker and/or employer. Two aspects of "flexible" arrangement of working hours were considered: one more subjected to company control and decision (variability) and one more connected to individual discretion and autonomy (flexibility). The aim of the study was to analyze these two dimensions in relation to health and well-being, taking into consideration the interaction with some relevant background variables related to demographics plus working and social conditions. The dataset of the Third European Survey on working conditions, conducted in 2000 and involving 21,505 workers, was used. Nineteen health disorders and four psycho-social conditions were tested by means of multiple logistic regression analysis, in which mutually adjusted odds ratios were calculated for age, gender, marital status, number of children, occupation, mode of employment, shift work, night work, time pressure, mental and physical workload, job satisfaction, and participation in work organization. The flexibility and variability of working hours appeared inversely related to health and psycho-social well-being: the most favorable effects were associated with higher flexibility and lower variability. The analysis of the interactions with the twelve intervening variables showed that physical work, age, and flexibility are the three most important factors affecting health and well-being. Flexibility resulted as the most important factor to influence work satisfaction; the second to affect family and social commitment and the ability to do the same job when 60 years old, as well as trauma, overall fatigue, irritability, and headache; and the third to influence heart disease, stomachache, anxiety, injury, and the feeling that health being at risk because of work. Variability was the third most important factor influencing family and social commitments. Moreover, shift and night work confirmed to

    2016-10-03

    This article aims to analyze work-to-family conflict (WFC) and enrichment (WFE) profiles related to job characteristics and well-being at work and general well-being. A cross-sectional survey data of 1885 employees was analyzed. The Latent Profile Analysis revealed that the five-profile solution exhibited strong statistical significance (p > .001). ANCOVAs were performed to analyze the relationship of the identified profiles with job characteristics and well-being. Employees in the Beneficial profile had the best perception of job characteristics (lowest demands and the highest control and support) and the highest well-being, and those in the Harmful profile had the lowest job characteristics perceptions and the lowest well-being. Through a comparison of the Moderate Active profile and the Moderate Harmful profile, WFE was found to buffer the effects of the WFC on well-being at work (burnout; engagement) and on general well-being (i.e., health perceptions). The promotion of WFE through higher job autonomy, job support, and fewer demands is a crucial aspect to consider. This study helps to consolidate the work-family balance typology and its effects on employees' well-being, and broadens this framework to consider job characteristics.

    OBJECTIVES: This study examined a project designed to improve the health and wellness of employees of Brabantia, a Dutch manufacturer of household goods, by means of lifestyle changes and changes in working conditions. METHODS: The workers at one Brabantia site constituted the experimental group, and the workers from two other sites formed the control group. Biomedical variables, lifestyles, general stress reactions, and quality of work were measured identically in both groups at baseline and 1, 2, and 3 years later. During this period, there was continuous registration of absenteeism. RESULTS: The interventions brought about favorable short-term changes in terms of health risks, and there were stable effects on working conditions (especially decision latitude) and absenteeism. CONCLUSIONS: A combination of interventions directed at both lifestyles and the work environment can produce extensive and stable effects on health-related variables, wellness, and absenteeism.

    2004-04-01

    This study examined how working in an organizational context perceived as hostile toward women affects employees' well-being, even in the absence of personal hostility experiences. Participants were 289 public-sector employees who denied any personal history of being targeted with general or gender-based hostility at work. They completed measures of personal demographics, occupational and physical well-being, and perceptions of the organizational context for women. Results showed that 2 contextual indices of hostility toward women related to declines in well-being for male and female employees. The gender ratio of the workgroup moderated this relationship, with employees in male-skewed units reporting the most negative effects. These findings suggest that all employees in the workplace can suffer from working in a context of perceived misogyny.

    ABSTRACT OBJECTIVE To analyze the relations between the meanings of working and the levels of doctors work well-being in the context of their working conditions. METHOD The research combined the qualitative methodology of textual analysis and the quantitative one of correspondence factor analysis. A convenience, intentional, and stratified sample composed of 305 Spanish and Latin American doctors completed an extensive questionnaire on the topics of the research. RESULTS The general meaning of working for the group located in the quartile of malaise included perceptions of discomfort, frustration, and exhaustion. However, those showing higher levels of well-being, located on the opposite quartile, associated their working experience with good conditions and the development of their professional and personal competences. CONCLUSIONS The study provides empirical evidence of the relationship between contextual factors and the meanings of working for participants with higher levels of malaise, and of the importance granted both to intrinsic and extrinsic factors by those who scored highest on well-being.

    The main aim of this study was to develop a short questionnaire to assess work-related well-being from the organizational behaviour perspective. The short well-being questionnaire enables measuring longitudinal work-related well-being. Work-related well-being was assessed with a 147-item questionnaire covering both organizational and intrinsic factors of work-related well-being. The questionnaire consisted of 27 categories. The respondents were 114 women (65%) and 62 men (35%), mean age 39.2 years, in various occupations. From the extensive questionnaire a shorter questionnaire with 33 items was developed by principal component analysis. The Kaiser-Meyer-Olkin measure to test the sampling adequacy of 27 factor solutions varied from .62 to .91 and Cronbach?s α was .74-.94. Most κ values of the shorter questionnaire were .50-.94 (p < .001). The reliability of the short version was comparable to that of the original questionnaire.

    Full Text Available Orientation: Hospital pharmacists in South Africa are experiencing increased stress because of the high demand for their services, a lack of resources in hospital pharmacies, and the shortage of pharmacists in South Africa.Research purpose: The objective of this study was to investigate whether job stress and coping strategies could predict the work-related well-being (burnout and work engagement of hospital pharmacists in South Africa.Motivation for the study: Information about the work-related well-being and coping strategies of hospital pharmacists could be used to plan individual and organisational interventions which can be used to retain them and to manage their well-being and performance.Research design, approach and method: A survey design was used. A stratified random sample (N = 187 of pharmacists in South African hospitals was studied. The Maslach Burnout Inventory – Human Services Survey, Utrecht Work Engagement Scale, Pharmacist Stress Inventory and the COPE questionnaire were administered.Main findings: The results showed that job related stress and three coping strategies (approach coping, avoidant coping, and turning to religion predicted burnout and work engagement of South African hospital pharmacists.Practical implications: Job stressors that are in the main responsible for the unfavourable work environment and that lead to the development of burnout amongst hospital pharmacists should be addressed. It is also important to enhance the coping capabilities of the hospital pharmacists.Contribution/value-add: The findings of this study provide insight into the factors impacting on the work-related well-being of hospital pharmacists in South Africa.

    This report documents the activities and findings of the Phase I Preliminary Characterization of Abandoned Septic Tank Systems. The purpose of the preliminary characterization activity was to investigate the Tiger Team abandoned septic systems (tanks and associated leachfields) for the purpose of identifying waste streams for closure at a later date. The work performed was not to fully characterize or remediate the sites. The abandoned systems potentially received wastes or effluent from buildings which could have discharged non-domestic, petroleum hydrocarbons, hazardous, radioactive and/or mixed wastes. A total of 20 sites were investigated for the preliminary characterization of identified abandoned septic systems. Of the 20 sites, 19 were located and characterized through samples collected from each tank(s) and, where applicable, associated leachfields. The abandoned septic tank systems are located in Areas 5, 12, 15, 25, and 26 on the Nevada Test Site.

    This study investigated the distinctiveness between workaholism and work engagement by examining their longitudinal relationships (measurement interval=7 months) with well-being and performance in a sample of 1,967 Japanese employees from various occupations. Based on a previous cross-sectional study (Shimazu & Schaufeli, 2009), we expected that workaholism predicts future unwell-being (i.e., high ill-health and low life satisfaction) and poor job performance, whereas work engagement predicts future well-being (i.e., low ill-health and high life satisfaction) and superior job performance. T1-T2 changes in ill-health, life satisfaction and job performance were measured as residual scores that were then included in the structural equation model. Results showed that workaholism and work engagement were weakly and positively related to each other. In addition, workaholism was related to an increase in ill-health and to a decrease in life satisfaction. In contrast, work engagement was related to a decrease in ill-health and to increases in both life satisfaction and job performance. These findings suggest that workaholism and work engagement are two different kinds of concepts that are oppositely related to well-being and performance.

    Kelloway, E K; Gottlieb, B H

    1998-01-01

    The growth of women's participation in the labor force and evidence of the conflict they experience between job and family demands have spurred many employers to introduce alternative work arrangements such as flextime, job sharing, and telecommuting. Drawing on data gained from a sample of women (N = 998) in two large Canadian organizations, this study evaluates two mediational models of the impact of alternative work arrangements on women's stress and family role competence. Specifically, it tests and finds support for the hypotheses that (a) work arrangements involving scheduling flexibility (telecommuting and flextime) promote these aspects of women's well-being by increasing their perceived control over their time, and (b) arrangements involving reduced hours of employment (part-time employment and job sharing) promote well-being by reducing perceived job overload. Discussion of these findings centers on their implications for employed women, their employers, and future research.

    The purpose of this correlational study was to investigate the relations between professional well-being (as characterized by positive attitudes toward work and longevity as a practicing music therapist) and the following factors: age, level of education, income, attitudes regarding the workplace (e.g., perceived control, feeling valued, as well as the amount of perceived comfort and input into administrative policies), attitudes toward work as measured by the Maslach Burnout Inventory (Maslach & Jackson, 1986a), and measures of stress and stress management as measured by the Stress Profile (Nowack, 1999a). Participants included 49 music therapists who had between one to 36 years of work experience. Correlations indicated that those respondents with greatest professional longevity tended to have higher ratings on items regarding cognitive coping strategies (e.g., positive appraisal and threat minimization) and greater perception of personal achievement. These correlational results are related to psychological theories regarding occupational burnout and cognitive hardiness.

  10. Work-family conflict and well-being in university employees.

    2014-01-01

    This is one of the first reported studies to have reviewed the role of work-family conflict in university employees, both academic and nonacademic. The goal of this research was to examine the role of work-family conflict as a mediator of relationships between features of the work environment and worker well-being and organizational outcomes. A sample of 3,326 Australian university workers responded to an online survey. Work-family conflict added substantially to the explained variance in physical symptoms and psychological strain after taking account of job demands and control, and to a lesser extent to the variance in job performance. However, it had no extra impact on organizational commitment, which was most strongly predicted by job autonomy. Despite differing in workloads and work-family conflict, academic ("faculty") and nonacademic staff demonstrated similar predictors of worker and organizational outcomes. Results suggest two pathways through which management policies may be effective in improving worker well-being and productivity: improving job autonomy has mainly direct effects, while reducing job demands is mediated by consequent reductions in work-family conflict.

    2016-06-01

    Hotel housekeepers are exposed to a plethora of disproportionately high work-induced hazards that can lead to adverse health consequences. Latina hotel housekeepers are rendered particularly vulnerable to elevated occupational hazards and resultant health strains due to their socioeconomic status, immigration status, language barriers, and lack of access to healthcare services. The findings from the 27 interviews with Latina hotel housekeepers indicated that the interviewees were exposed to physical, chemical, and social hazards in the workplace and suffered musculoskeletal injuries. In terms of psychological wellness, the time pressure of cleaning rooms quickly and work-related stress stemming from workplace mistreatment emerged as major work-related stressors. Recommendations are made for the introduction of multilevel interventions designed to prevent work-related injuries and illnesses and to promote healthier workplaces.

    This study examined the role of partners and children for employees' psychological detachment from work during off-job time. Building on boundary theory, we hypothesized that not only employees' own work-home segmentation preference but also their partners' work-home segmentation preference is associated with employees' psychological detachment. In addition, partners' psychological detachment should influence employees' psychological detachment. We hypothesized that the presence of children in the household moderates partners' influence on employees' psychological detachment. Further, we expected both employees' and their partners' psychological detachment to contribute to employees' well-being. Participants were 114 dual-earner couples who responded to Web-based questionnaires. The hypotheses were tested with multilevel analyses, using the actor-partner interdependence model. Results confirmed our hypotheses. Employees' and their partners' work-home segmentation preferences were associated with employees' psychological detachment. The presence of children moderated the relation between partners' work-home segmentation preference and employees' psychological detachment. The relation was weaker when there were children in the household. Moreover, employees' and their partners' psychological detachment were positively associated. Again, the relation was weaker when there were children in the household. Finally, both employees' and their partners' psychological detachment contributed to employees' well-being.

    2016-09-13

    Based on an adjusted Job Demands-Resources (JD-R) model that considers the mediation of personal resources, this study examined the relationships between two characteristics of teachers' work environment (i.e., emotional job demands and trust in colleagues) and two indicators of teachers' well-being (i.e., teaching satisfaction and emotional exhaustion). In particular, the study focused on how emotion regulation strategies (i.e., reappraisal and suppression) mediate these relationships. Data collected from a questionnaire survey of 1115 primary school teachers in Hong Kong was analyzed to test the hypothesized relationships. The results of structural equation modeling indicated that: (1) the emotional job demands of teaching were detrimental to teacher well-being, whereas trust in colleagues was beneficial; (2) both emotion regulation strategies mediated the relationships between both emotional job demands and trust in colleagues and teacher well-being; and (3) teachers who tend to use more reappraisal may be psychologically healthier than those tend to adopt more suppression. These findings support the applicability of the JD-R model to school settings and highlight the role of teachers' emotion regulation in teachers' well-being. Implications for the improvement of school environments and teachers' well-being are identified.

    Construction well divers in Taiwan reportedly suffer a high prevalence of dysbaric osteonecrosis. We studied five divers working at the same construction site. We recorded their diving methods, diving depths, bottom times, work patterns, water temperatures, and heart rates. We also monitored gas bubbles in the subclavian vein in selected dives. A crude but effective hot-water system protected divers against hypothermia and allowed them to work in 24 degrees-27 degrees C water. Divers worked approximately 6.6 h a day and progressed approximately 3.0 m a day while excavating an average of 148 buckets of sand and rock each weighing 49.5 kg. The divers sustained a heart rate increase of 49%. Sixty percent of their equivalent single dive bottom times exceeded the U.S. Navy's no-decompression limits. Two cases of venous bubbles were detected, and one of these divers showed symptoms of decompression sickness. The prolonged bottom time and lack of a decompression schedule probably contributed to a risk of decompression sickness and dysbaric osteonecrosis.

    Dealing with negative emotions is a crucial work demand, particularly for employees in health care. Job resources (e.g., autonomy, social support, or reward) but also personal resources (such as emotion regulation strategies) might reduce job stress and support well-being. Following this, the present study focused on strengthening emotion regulation as 1 way of dealing with high job demands. The aim of this study was to evaluate the impact of a standardized emotion regulation training (Affect Regulation Training [ART]; Berking, 2010) to improve emotion regulation skills and well-being of employees in elderly health care. Therefore, 96 elderly care workers filled out an established questionnaire of emotion regulation skills as well as a measure of well-being at pretreatment, posttreatment and at 6-month follow-up. The findings show that the ART fosters emotion regulation skills. In particularly, acceptance, tolerance, and modification of negative emotions was enhanced in the training groups in comparison to a control-group. Modification, meaning the ability to actively change emotions, improved even more over the follow-up-period. Simultaneously, well-being of participants increased over all measurement time points in the ART-group compared with the control-group. Additionally, the improvement in emotion regulation skills from pre to posttreatment was related to well-being at follow-up. In summary, our results support the ART as an effective intervention for dealing with negative emotions and to enhance well-being among employees in elderly care. (PsycINFO Database Record

    The relation of fathers' participation in family work (child care and home chores) to parents' role strain and well-being was examined in an interview study of 160 Caucasian middle-class fathers and mothers of kindergarten and fourth-grade children. In half of the families, mothers were employed. Four forms of paternal participation were examined. Role-strain items referred to immediate and specific problems such as time and energy constraints and role conflicts. Well-being measures assessed self-esteem, life satisfaction, and quality of experience in the parental and marital roles. Regression analyses, carried out separately for fathers and for mothers, indicated that, contrary to expectation, when the level of fathers' participation was controlled maternal employment did not condition the relation between participation and the outcome variables. Findings varied for the different forms of participation. For fathers, higher levels of participation were associated with feeling more involved and competent as a parent and with being more critical of wives' patterns and parenting. For mothers, those whose husbands were more participant praised their husbands' parenting, but they were lower in life satisfaction and were more self-critical about their balance of work and family responsibilities.

    Those working in the fields of harm reduction, healthcare, and human services must cope with a range of stresses, including post traumatic stress and vicarious trauma. Pain and loss are just a part of the job. So is dealing with premature death as a result of HIV, hypertension, and even overdose. Faced with a range of challenges, some workers in the field even turn to self-medication. For some, it is about pleasure; for others it is about alleviating suffering. In recent years, several leaders in the AIDS and harm reduction fields have died ahead of their time. Some stopped taking their medications; others overdosed. Rather than weakness or pathology, French sociologist Emile Durkheim saw self-destructive behavior as a byproduct of social disorganization and isolation, as a way of contending with a breakdown of social bonds and alienation. There are any number of reasons why such behavior becomes part of work for those involved with battling the dueling epidemics of Hepatitis C, HIV, and related concerns. Forms of stress related to this work include secondary trauma, compassion fatigue, organizational conflict, burnout, complications of direct services, and lack of funding. Faced with day-to- day struggles over poverty, punitive welfare systems, drug use, the war on drugs, high risk behavior, structural violence, and illness, many in the field are left to wonder how to strive for wellness when taking on so much pain. For some, self-injury and self-medication are ways of responding. Building on ethnographic methods, this reflective analysis considers the stories of those who have suffered, as well as a few of the ways those in the field cope with harm and pain. The work considers the moral questions we face when we see our friends and colleagues suffer. It asks how we as practitioners strive to create a culture of wellness and support in the fields of harm reduction, healthcare, and human services.

    Full Text Available Authentic leadership has been purported to influence psychological well-being through its impact on work climate. Using a sample of 406 nurses, a time-lagged study design was employed to determine the mediational role of work climate in explaining the impact of authentic leadership. Two self-reported questionnaires were completed to ascertain: (1 authentic leadership; and (2 work climate at baseline. In addition, nurses completed a measure to determine their level of psychological well-being at work at the 6 month time period. A mediation analysis with the use of a bootstrapping technique reveals that work climate mediates the relationship between authentic leadership and psychological well-being at work. These findings indicate that authentic leadership impacts the work climate in a positive manner; thereby, increasing levels of psychological well-being at work. We discuss theoretical and practical implications of the findings for future research as well as outline some limitations.

    Full Text Available Abstract Background The transition from medical student to junior doctor in postgraduate training is a critical stage in career progression. We report junior doctors' views about the extent to which their medical school prepared them for their work in clinical practice. Methods Postal questionnaires were used to survey the medical graduates of 1999, 2000, 2002 and 2005, from all UK medical schools, one year after graduation, and graduates of 2000, 2002 and 2005 three years after graduation. Summary statistics, chi-squared tests, and binary logistic regression were used to analyse the results. The main outcome measure was the level of agreement that medical school had prepared the responder well for work. Results Response rate was 63.7% (11610/18216 in year one and 60.2% (8427/13997 in year three. One year after graduation, 36.3% (95% CI: 34.6, 38.0 of 1999/2000 graduates, 50.3% (48.5, 52.2 of 2002 graduates, and 58.2% (56.5, 59.9 of 2005 graduates agreed their medical school had prepared them well. Conversely, in year three agreement fell from 48.9% (47.1, 50.7 to 38.0% (36.0, 40.0 to 28.0% (26.2, 29.7. Combining cohorts at year one, percentages who agreed that they had been well prepared ranged from 82% (95% CI: 79-87 at the medical school with the highest level of agreement to 30% (25-35 at the lowest. At year three the range was 70% to 27%. Ethnicity and sex were partial predictors of doctors' level of agreement; following adjustment for them, substantial differences between schools remained. In years one and three, 30% and 34% of doctors specified that feeling unprepared had been a serious or medium-sized problem for them (only 3% in each year regarded it as serious. Conclusions The vast knowledge base of clinical practice makes full preparation impossible. Our statement about feeling prepared is simple yet discriminating and identified some substantial differences between medical schools. Medical schools need feedback from graduates about

  18. Superconductivity in optimally doped cuprates: BZA program works well and superexchange is the glue

    Directory of Open Access Journals (Sweden)

    G. Baskaran

    2006-09-01

    Full Text Available   Resonating valence bond states in a doped Mott insulator was proposed to explain superconductivity in cuprates in January 1987 by Anderson. A challenging task then was proving existence of this unconventional mechanism and a wealth of possibilities, with a rigor acceptable in standard condensed matter physics, in a microscopic theory and develop suitable many body techniques. Shortly, a paper by Anderson, Zou and us (BZA undertook this task and initiated a program. Three key papers that followed, shortly, essentially completed the program, as far as superconductivity is concerned,i a gauge theory approach by Anderson and us, that went beyond mean field theory ii Kotliar’s d -wave solution in BZA theory iii improvement of a renormalized Hamiltonian in BZA theory, using a Gutzwiller approximation by Zhang, Gros, Rice and Shiba. In this article I shall focus on the merits of BZA and gauge theory papers. They turned out to be a foundation for subsequent developments dealing with more aspects that were unconventional - d -wave order parameter with nodal Bogoliubov quasi particles, Affleck-Marston’s π-flux condensed spin liquid phase, unconventional spin-1 collective mode at (π, π, and other fascinating developments. Kivelson, Rokhsar and Sethna’s idea of holons and their bose condensation found expression in the slave boson formalism and lead to results similar to BZA program. At optimal doping, correlated electrons acquire sufficient fermi sea character, at the same time retain enough superexchange inherited from a Mott insulator parentage, ending in a BCS like situation with superexchange as a glue! Not surprisingly, mean field theory works well at optimal doping, even quantitatively. Further, t-J model is a minimal model only around optimal doping, where RVB superconductivity is also at its best.

  20. Estimating Limits for the Geothermal Energy Potential of Abandoned Underground Coal Mines: A Simple Methodology

    Directory of Open Access Journals (Sweden)

    Rafael Rodríguez Díez

    2014-07-01

    Full Text Available Flooded mine workings have good potential as low-enthalpy geothermal resources, which could be used for heating and cooling purposes, thus making use of the mines long after mining activity itself ceases. It would be useful to estimate the scale of the geothermal potential represented by abandoned and flooded underground mines in Europe. From a few practical considerations, a procedure has been developed for assessing the geothermal energy potential of abandoned underground coal mines, as well as for quantifying the reduction in CO2 emissions associated with using the mines instead of conventional heating/cooling technologies. On this basis the authors have been able to estimate that the geothermal energy available from underground coal mines in Europe is on the order of several thousand megawatts thermal. Although this is a gross value, it can be considered a minimum, which in itself vindicates all efforts to investigate harnessing it.

  5. 'They might as well brand us': working-class resistance to compulsory vaccination in Victorian England.

    Science.gov (United States)

    Durbach, N

    2000-04-01

    From its origins in resistance to the 1853 Compulsory Vaccination Act, the Victorian anti-vaccination movement successfully challenged the public health policies of an increasingly interventionist state. Anti-vaccinationists were not only middle-class reformers, but were also drawn from a politically active working class. These campaigners saw compulsory vaccination as an extreme example of class legislation, for its policy and administration implicitly targeted working-class infants and inflicted multiple penalties on a public who considered themselves 'conscientious objectors'. Anti-vaccinationism was quickly absorbed into English working-class culture. Indeed, it helped to reorganize working-class identities around the site of the vulnerable body thereby absorbing many people into a working class who interpreted the violation of their bodies as a form of political tyranny. Participation in this movement was, however, also an exclusive exercise for anti-vaccinators, as respectable working-class citizens distinguished themselves from members of the 'undeserving' classes. This paper explores the class nature of the Vaccination Acts, their relationship to the New Poor Law, and the political implications of their administration. It also imbeds anti-vaccinationism firmly within working-class culture, illustrating the campaign's relationship to popular protest and entertainment, and this legislation's impact upon working-class bodies.

  6. Who abandons embryos after IVF?

    Walsh, A P H

    2010-04-01

    This investigation describes features of in vitro fertilisation (IVF) patients who never returned to claim their embryos following cryopreservation. Frozen embryo data were reviewed to establish communication patterns between patient and clinic; embryos were considered abandoned when 1) an IVF patient with frozen embryo\\/s stored at our facility failed to make contact with our clinic for > 2 yrs and 2) the patient could not be located after a multi-modal outreach effort was undertaken. For these patients, telephone numbers had been disconnected and no forwarding address was available. Patient, spouse and emergency family contact\\/s all escaped detection efforts despite an exhaustive public database search including death records and Internet directory portals. From 3244 IVF cycles completed from 2000 to 2008, > or = 1 embryo was frozen in 1159 cases (35.7%). Those without correspondence for > 2 yrs accounted for 292 (25.2%) patients with frozen embryos; 281 were contacted by methods including registered (signature involving abandoned embryos did not differ substantially from other patients. The goal of having a baby was achieved by 10\\/11 patients either by spontaneous conception, adoption or IVF. One patient moved away with conception status unconfirmed. The overall rate of embryo abandonment was 11\\/1159 (< 1%) in this IVF population. Pre-IVF counselling minimises, but does not totally eliminate, the problem of abandoned embryos. As the number of abandoned embryos from IVF accumulates, their fate urgently requires clarification. We propose that clinicians develop a policy consistent with relevant Irish Constitutional provisions to address this medical dilemma.

    2016-09-01

    Full Text Available State Holding Company makes a number of improvements, followed by a process of changes each year. This study was conducted to understand how the changes in the company affect the employees working in it and how the employees deal with the stress caused by such changes. The purpose of the study was to investigate the links between personnel work stress, subjective and psychological well-being of employees during changes in State Holding Company. The research undertakes issues such as: the levels of employee stress and subjective well-being, the levels of employee psychological well-being, links, if any, between subjective and psychological well-being and work stress, and the methods used in the research study. The survey was created with reference to works of other authors such as “Professional Life Stress Scale”, “Life Satisfaction Scale” and “Psychological Well-being Survey”. It was concluded that the employees had medium levels of stress, medium levels of life satisfaction, and medium levels of overall psychological well-being. There are statistically significant links between subjective well-being, psychological well-being and work stress. Recommendations were prepared for the Human Resources Department to reduce stress levels of personnel working and successful management of changes.

    2014-06-01

    Measuring spiritual well-being among clergy is particularly important given the high relevance of God to their lives, and yet its measurement is prone to problems such as ceiling effects and conflating religious behaviors with spiritual well-being. To create a measure of closeness to God for Christian clergy, we tested survey items at two time points with 1,513 United Methodist Church clergy. The confirmatory factor analysis indicated support for two, six-item factors: Presence and Power of God in Daily Life, and Presence and Power of God in Ministry. The data supported the predictive and concurrent validity of the two factors and evidenced high reliabilities without ceiling effects. This Clergy Spiritual Well-being Scale may be useful to elucidate the relationship among dimensions of health and well-being in clergy populations.

    2015-04-01

    There is consistent evidence suggesting a relationship between individuals' sleep-wake rhythms and well-being. The indiscriminate demands from daily working routines, which do not respect this individual physiological rhythm, might be mediating this phenomenon. The aim of the present study was to evaluate the relationship between the characteristics of sleep routines during working days and psychological well-being. This was a cross-sectional study on 825 individuals from rural communities from southern Brazil. The study protocol included a questionnaire on demographic characteristics, working routines, health complaints, and habits; the Munich Chronotype Questionnaire for sleep-wake rhythm and; the WHO-Five well-being index. Since sex has been shown to affect sleep circadian rhythm and well-being, analysis was performed on men and women separately. In the proposed hierarchical regression models, different factors contributed to well-being according to sex. Among men, sleep-wake and work-related variables did not predict well-being scores. Among women, later midpoints of sleep on working days (B = -1.243, SE B = 0.315, β = -0.220), working more days per week (B = -1.507, SE B = 0.494, β = 0.150), having longer working journeys (B = -0.293, SE B = 0.105, β = -0.166), earlier working journey midpoints (B = 0.465, SE B = 0.222, β = 0.115), and being exposed to less sunlight (B = 0.140, SE B = 0.064, β = 0.103) predicted worse well-being. For the subgroup of women with days free from work, we have found a correlation between later midpoints of sleep during the week with worse well-being (Pearson's r = -0.159, p = 0.045) while the same relationship was not significantly observed with the midpoint of sleep on non-working days (Pearson's r = -0.153, p = 0.054). Considering WHO-Five as categorical, based on proposed clinical cut-offs, among women working 7-d/week, those with worst well

  1. Localized Detection of Abandoned Luggage

    Directory of Open Access Journals (Sweden)

    Jing-Ying Chang

    2010-01-01

    Full Text Available Abandoned luggage represents a potential threat to public safety. Identifying objects as luggage, identifying the owners of such objects, and identifying whether owners have left luggage behind are the three main problems requiring solution. This paper proposes two techniques which are “foreground-mask sampling” to detect luggage with arbitrary appearance and “selective tracking” to locate and to track owners based solely on looking only at the neighborhood of the luggage. Experimental results demonstrate that once an owner abandons luggage and leaves the scene, the alarm fires within few seconds. The average processing speed of the approach is 17.37 frames per second, which is sufficient for real world applications.

  2. Dual-earner families: the importance of work stress and family stress for psychological well-being.

    Science.gov (United States)

    Schwartzberg, N S; Dytell, R S

    1996-04-01

    Scales of work stress and family stress as well as outcome measures of depression and self-esteem were completed by 94 mothers and 48 fathers in dual-earner families. Working mothers and working fathers reported equivalent levels of family stress, work stress, job-family interference, and psychological well-being, although mothers did report a higher level of lack of task sharing. Self-esteem and depression of dual-earner mothers and fathers were affected by both job and family stress. Insignificance within their work role affected both self-esteem and depression. Lack of task sharing significantly predicted depression among dual-earner mothers. Lack of challenge in their work role appeared to be a positive characteristic for dual-earner fathers.

    2014-11-01

    In the present study, we examine competing predictions of stress reaction models and adaptation theories regarding the longitudinal relationship between work-family conflict and subjective well-being. Based on data from 432 participants over 3 time points with 2 lags of varying lengths (i.e., 1 month, 6 months), our findings suggest that in the short term, consistent with prior theory and research, work-family conflict is associated with poorer subjective well-being. Counter to traditional work-family predictions but consistent with adaptation theories, after accounting for concurrent levels of work-family conflict as well as past levels of subjective well-being, past exposure to work-family conflict was associated with higher levels of subjective well-being over time. Moreover, evidence was found for reverse causation in that greater subjective well-being at 1 point in time was associated with reduced work-family conflict at a subsequent point in time. Finally, the pattern of results did not vary as a function of using different temporal lags. We discuss the theoretical, research, and practical implications of our findings.

    2014-11-01

    This article describes an ethnographic study focused on exploring leaders of team learning in well-established nephrology teams in an academic healthcare organization in Canada. Employing situational theory of leadership, the article provides details on how well established team members advance as "learning leaders". Data were gathered by ethnographic methods over a 9-month period with the members of two nephrology teams. These learning to care for the sick teams involved over 30 regulated health professionals, such as physicians, nurses, social workers, pharmacists, dietitians and other healthcare practitioners, staff, students and trainees, all of whom were collectively managing obstacles and coordinating efforts. Analysis involved an inductive thematic analysis of observations, reflections, and interview transcripts. The study indicated how well established members progress as team-learning leaders, and how they adapt to an interprofessional culture through the activities they employ to enable day-to-day learning. The article uses situational theory of leadership to generate a detailed illumination of the nature of leaders' interactions within an interprofessional context.

    Work in the field of sexual abuse is extremely stressful and may arouse negative personal reactions. Although these secondary trauma effects are well described on a personal level, there is not enough evidence to understand whether these professionals carry these effects to their homes, families, and offspring. This study aims to identify the effects of working with child abuse cases on the anxiety level and parenting styles of childhood trauma workers and on their children's well-being. A total of 43 health and legal system workers who worked with abused children in any step of their process and who had children constituted the study group, and 50 control cases, each working in the same institution and having the same occupation as 1 of the participants from the study group and having children but not working directly with children and child abuse cases, were included in the study. Participants were asked to fill out a sociodemographic form, the Parental Attitude Research Instrument, the trait portion of the State-Trait Anxiety Inventory, and an age-appropriate form of the Child Behavior Checklist for each child they had. Professionals in the study working with child abuse cases demonstrated significantly higher democratic parenting attitudes. Law enforcement workers working with child abuse cases demonstrated stricter and more authoritarian parenting strategies, as well as more democratic attitudes, than their colleagues. There was not a statistically significant relationship between child abuse workers' anxiety level and their children's well-being among control subjects.

    This works tries to establish the performance of truncated CI calculations on the evaluation of magnetic coupling parameters with respect to available FCI estimates on a set of carbon-beryllium clusters. First-, second- and third-neighbor magnetic coupling constants have been evaluated and many body effective parameters as the cyclic terms. They result from the fitting of the low-lying states to the eigenvalues of an extended Heisenberg Hamiltonian, involving not only two-body isotropic terms but also cyclic terms. SDCI and DDCI calculations have been carried out and their performance compared with FCI ones. The impact of the basis set choice and size-consistency errors have been explored.

    Phase-sensitive radar (pRES) has become one of the mostly used tools to determine basal melt rates as well as vertical strain in ice sheets. Whereas most applications are performed on ice shelves, only few experiments were conducted on thick ice in Greenland or Antarctica. The technical constrains on an ice shelf to deduce basal melt rates are less demanding than on inland ice of more than 2 km thickness. First, the ice itself is usually only several 100s of meters thick; and, second, the reflection coefficient at the basal interface between sea water and ice is the second strongest one possible. Although the presence of marine ice with higher conductivities might increase attenuation in the lower parts, most experiments on shelves were successful. To transfer this technology to inland regions, either for the investigation of basal melt rates of subglacial hydrological networks or for determining vertical strain rates in basal regions, a reliable estimate of the current system performance is necessary. To this end we conducted an experiment at and in the vicinity of the EPICA deep ice core drill site EDML in Dronning Maud Land, Antarctica. That site has been explored in extraordinary detail with different geophysical methods and provides an already well-studied ice core and borehole, in particular with respect to physical properties like crystal orientation fabric, dielectric properties and matching of internal radar horizons with conductivity signals. We present data from a commercially available pRES system initially recorded in January 2015 and repeated measurements in January 2016. The pRES data are matched to existing and already depth-calibrated airborne radar data. Apart from identifying prominent internal layers, e.g. the one originating from the deposits of the Toba eruption at around 75 ka, we put special focus on the identification of the basal reflection at multiple polarizations. We discuss the potential uncertainty estimates and requirements to

    The aim of the present study is to demonstrate the empirical distinctiveness of workaholism and work engagement by examining their relationships with well-being in a sample of 776 Japanese employees. We expected that workaholism is associated with unwell-being (i.e., high psychological distress and physical complaints, low job and family satisfaction, and low job performance), whereas work engagement is associated with well-being. Well-validated questionnaires were used to measure workaholism (DUWAS), work engagement (UWES), and well-being (BJSQ, HPQ). Structural Equation Modeling showed that, as expected, workaholism was positively associated with ill-health (i.e., psychological distress and physical complaints) and negatively associated with life satisfaction (i.e., job and family satisfaction) and job performance. In contrast, work engagement was negatively associated with ill-health and positively associated with life satisfaction and job performance. These findings suggest that workaholism and work engagement are two different kinds of concepts, which are negatively and positively related to various indicators of well-being, respectively.

    The decision of where, when, and how to apply the most effective postfire erosion mitigation treatments requires land managers to assess the risk of damaging runoff and erosion events occurring after a fire. The Erosion Risk Management Tool (ERMiT) was developed to assist post fire assessment teams identify high erosion risk areas and effectiveness of various mitigation treatments to reduce that risk. ERMiT is a web-based application that uses the Water Erosion Prediction Project (WEPP) technology to estimate erosion, in probabilistic terms, on burned and recovering forest, range, and chaparral lands with and without the application of mitigation treatments. User inputs are processed by ERMiT to combine rain event variability with spatial and temporal variabilities of hillslope burn severity and soil properties which are then used as WEPP inputs. Since 2007, the model has been used in making hundreds of land management decisions in the US and elsewhere. We use eight published field study sites in the Western US to compare ERMiT predictions to observed hillslope erosion rates. Most sites experience only a few rainfall events that produced runoff and sediment except for a California site with a Mediterranean climate. When hillslope erosion occurred, significant correlations occurred between the observed hillslope erosion and those predicted by ERMiT. Significant correlation occurred for most mitigation treatments as well as the five recovery years. These model validation results suggest reasonable estimates of probabilistic post-fire hillslope sediment delivery when compared to observation.

Participants interacted with clients on average 5.44 hr a day (SD 2.41). The mean working time was 7.36 hr per day (SD 1.91)."] Negative work events can diminish daily occupational well-being, yet the degree to which they do so depends on the way in which people deal with their emotions. The aim of the current study was to examine the role of acceptance in the link between daily negative work events and occupational well-being. We hypothesized that acceptance would be associated with better daily occupational well-being, operationalized as low end-of-day negative emotions and fatigue, and high work engagement. Furthermore, we predicted that acceptance would buffer the adverse impact of negative work events on daily well-being. A microlongitudinal study across 10 work days was carried out with 92 employees of the health care sector, yielding a total of 832 daily observations. As expected, acceptance was associated with lower end-of-day negative emotions and fatigue (though there was no association with work engagement) across the 10-day period. Furthermore, acceptance moderated the effect of negative event occurrence on daily well-being: Highly accepting employees experienced less increase in negative emotions and less reduction in work engagement (though comparable end-of-day fatigue) on days with negative work events, relative to days without negative work events, than did less accepting employees. These findings highlight affective, resource-saving, and motivational benefits of acceptance for daily occupational well-being and demonstrate that acceptance is associated with enhanced resilience to daily

  20. How well does end-member modelling analysis of grain size data work?

    2014-05-01

    End-member modelling analysis (EMMA) is a powerful and flexible statistic approach to identify and quantify generic sediment transport processes from multimodal grain-size distributions. EMMA has been introduced over 15 years ago and is now available in different approaches as encapsulated FORTRAN code (Weltje, 1997), Matlab-script (Dietze et al., 2012) and the R-package EMMAgeo (Dietze and Dietze, 2013). EMMA was mainly used to reconstruct past sedimentation processes in a variety of sedimentary environments (marine, aeolian, lacustrine). Typically, it is rather difficult to assess how meaningful and well the model performs in a certain environment, since neither the actual process end-members (generic grain-size distributions sorted by a certain sediment transport) nor their individual contributions to each sample are known a priori. To allow a comprehensive performance test, we sampled a set of four known process end-members: alluvial sand (main mode: 0.70±0.55 φ), dune sand (main mode: 1.35±0.60 φ), loess (main mode: 4.71±0.65 φ) and overbank deposit (main mode: 5.81±1.62 φ). High resolution grain-size information is based on laser-diffraction analysis (116 classes). The four process end-members were artificially mixed with random, but known proportions to yield 100 samples. This mixed data set was measured again with the laser particle size analyser and served as input for EMMA within the R-package EMMAgeo. This contribution discusses the ability of EMMA to identify and characterise the four distinct process end-members and quantify their contributions to each sample. Different ways to estimate uncertainties are presented. Further evaluations focus on the influence of numbers of included samples, numbers of grain-size classes, vertical mixing of samples (simulating turbation) and self-similarity of process end-members.

    We examine relations between perceived organisational autonomy support and different types of work motivation and well-being outcomes in 266 teachers from two government schools in China. We hypothesised that greater autonomy support would be associated with more autonomous forms of employee motivation, and that teacher motivation would in turn mediate the effects of autonomy support on indicators of work well-being (i.e., job satisfaction, work stress and physical ill symptoms). Results generally supported the hypothesised relations between perceived autonomy support and SDT's five types of motivations. Findings also showed that perceived autonomy support predicted job satisfaction directly and indirectly through the mediating roles of intrinsic motivation, identified regulation, introjected regulation and external regulation. Perceived autonomy support predicted work stress directly and indirectly through the mediating roles of external regulation and amotivation. Autonomy support also predicted illness symptoms via the mediating roles of intrinsic motivation, introjected regulation and amotivation. The current findings highlight how perceived organisational support for autonomy relates to motivational differences in a Chinese work context, and the potential relevance of autonomy support for employee well-being.

    The issue of the assessment of work-related stress has stimulated in recent years, the production of several theoretical paradigms and assessment tools. In this paper we present a new scale for the assessment of organizational well-being and work-related stress specific for healthcare organizations (Work-related Stress Assessment Scale - WSAS). The goal of the authors is to examine the psychometric properties of the scale, so that it can be used in the healthcare setting as a work-related stress assessment tool. The answers of 230 healthcare professionals belonging to different roles have been analyzed. The study was realized in 16 Units of the University Hospital "S. Maria alle Scotte "of Siena. The exploratory factor analysis (EFA) revealed the presence of five factors with good internal consistency and reliability, "relationship to the structure of proximity" (α = 0.93) "change" (α = 0.92), "organization of work "(α = 0.81)," relationship with the company / Governance "(α = 0.87)" working environment "(α = 0.83). The analysis of SEM (Structural Equation Models) has confirmed the goodness of the factor solution (NNFI = 0.835, CFI = 0.921, RMSEA = 0.060). The good psychometric qualities, the shortness and simplicity of the scale WSAS makes it a useful aid in the assessment of work-related stress in health care organizations.

    Full Text Available Abstract Background A large body of international research reveals that single mothers experience poorer mental health than their partnered counterparts, with socioeconomic disadvantage identified as an important contributory factor in understanding this health disparity. Much less research, however, has focused specifically on the psychological well-being of single mothers who are employed, despite their growing presence in the labor force. Of the research which has considered employment, the focus has been on employment status per se rather than on other important work-related factors which may impact psychological health, such as psychosocial work quality and work-family conflict. The aim of this study was to: (1 compare employed single mothers and employed partnered mothers on measures of psychological distress, psychosocial work quality and work-family conflict; and (2 explore the potential role of work-family conflict and psychosocial work quality as explanations for any observed differences in psychological distress based on partner status. Method Analysis of data obtained from a cross-sectional telephone survey of employed parents in a mid-sized Western Canadian city. Analyses were based on 674 employed mothers (438 partnered and 236 single, who were 25-50 years old, with at least one child in the household. Results Compared to employed single mothers, employed partnered mothers were older, had more education and reported fewer hours of paid work. Single mothers reported higher levels of psychological distress, financial hardship, work-family conflict and poor psychosocial work quality. Statistical adjustment for income adequacy, psychosocial work quality and work-family conflict each independently resulted in single motherhood no longer being associated with psychological distress. Conclusions While single employed mothers did experience higher levels of psychological distress than their partnered counterparts, differences between these

    Widespread cropland abandonment occurred after the collapse of socialism across the former Soviet Union, but the rates and spatial patterns of abandoned lands are not well known. As a result, the potential of this region to contribute to global food production and estimates of the carbon sink developing on currently idle lands are highly uncertain. We developed a spatial allocation model that distributes yearly and subnational sown area statistics to the most agriculturally suitable plots. This approach resulted in new, high-resolution (1 km2) annual time series of cropland and abandoned lands in European Russia, Ukraine, and Belarus from 1990 to 2009. A quantitative validation of the cropland map confirms the reliability of this data set, especially for the most important agricultural areas of the study region. Overall, we found a total of 87 Mha of cropland and 31 Mha of abandoned cropland in European Russia, Ukraine, and Belarus combined, suggesting that abandonment has been severely underestimated in the past. The abandonment rates were highest in European Russia. Feeding our new map data set into the dynamic vegetation model LPJmL revealed that cropland abandonment resulted in a net carbon sink of 470 TgC for 1990 to 2009. Carbon sequestration was generally slow in the early years after abandonment, but carbon uptake increased significantly after approximately 10 years. Recultivation of older abandoned lands would be associated with high carbon emissions and lead to substantial amounts of carbon not being sequestered in vegetation formations currently developing on idle croplands. Our spatially and temporally explicit cropland abandonment data improve the estimation of trade-offs involved in reclaiming abandoned croplands and thus in increasing agricultural production in this globally important agricultural region.

    New principles of work and energy as well as power and energy rate with cross terms for polar and nonlocal polar continuum field theories were presented and from them all corresponding equations of motion and boundary conditions as well as complete equations of energy and energy rate with the help of generalized Piola' s theorems were naturally derived in all and without any additional requirement. Finally, some new balance laws of energy and energy rate for generalized continuum mechanics were established. The new principles of work and energy as well as power and energy rate with cross terms presented in this paper are believed to be new and they have corrected the incompleteness of all existing corresponding principles and laws without cross terms in literatures of generalized continuum field theories.

    Although previous theory and research suggest that employee well-being should be predicted by work conditions (viz., Karasek and colleagues' job demands-control-social support [J-DCS] model), other factors are also likely to be important. In this study, the authors consider correlates of employee psychological distress and well-being using a goal-focused approach grounded in Ford's (1992) motivational systems theory. Specifically, work conditions and midlevel work goal processes (WGP) were examined in a questionnaire study of health care employees. Regarding predictions derived from the J-DCS model, the authors found full support for the iso-strain, partial support for the nonlinearity, and no support for the buffer hypothesis. Of importance, however, WGP (i.e., cognitions and emotions involved in the pursuit of self-set work goals) explained variance in job satisfaction, burnout, depression, and somatic complaints, over and above that of the J-DCS model. This suggests that investigation of WGP can enhance our understanding of employee psychological distress and well-being.

    Full Text Available It is well established that negative work-home interference (NegWHI impacts upon several work attitudes and behaviors. In the interests of both organizational effectiveness and employee well-being, it is important to identify concepts related to NegWHI and investigate their effects on well-being outcomes. This study examines the mediating role of (1 perceived organizational support (POS in the relationship between organizational justice (OJ and NegWHI; and (2 NegWHI in the relationships between POS and four well-being outcomes. A total of 509 employees of a Belgian hospital were surveyed. Data were analyzed using structural equation modeling and the bootstrapping method. Results showed that POS partially mediates the relationships between distributive and passive procedural justice and NegWHI, and fully mediates the relationship between the other justice dimensions and NegWHI. NegWHI partially mediates the relationships between POS and both job satisfaction and intention to quit, and fully mediates the relationship between POS and job strain. Furthermore, POS is positively related to job engagement. This study showed that organizations can help employees to better manage their work and family lives and reduce the impact of NegWHI by enhancing employees’ feeling that they are supported by their organization. In order to increase POS, organizations need to promote justice in the workplace.

    Using data from the first two waves of the Netherlands Kinship Panel Study for 338 women and 262 men, we examine the consequences of making the transition to parenthood for life satisfaction, loneliness, positive affect, negative affect, and partnership satisfaction. We extend previous work by taking transitions in partner status and work hours into account. Results show a moderate impact of becoming a parent on well-being. In so far as effects of making the transition to parenthood emerge, they are attributable to changes in partner status and work hours. First, the decrease in negative affect upon making the transition to motherhood is attributable to the group of women who increase their working hours. Second, the detrimental impact of making the transition to motherhood on partnership satisfaction is attributable to the group of new mothers who quit their job. Third, the detrimental impact of making the transition to fatherhood on loneliness is attributable to the group of new fathers who become married. There is one exception to this pattern of partner status and work hours as mechanisms for changes in well-being. Men who become fathers remain less satisfied with their partnership, even when transitions in partner status and work hours have been taken into account. In the discussion-section, we consider the possible underestimation of negative effects because of the focus on the continuously partnered. We also reflect on our results in the light of the high incidence of part-time work in the Netherlands and Dutch policies aimed at supporting new parents.

    Many European mothers, single and coupled, combine work outside the home and family life. The effects of this on their mental well-being may vary depending on the level of support available from the State's welfare system, since welfare may buffer working mothers from some of the stress that can arise from trying to manage significant responsibilities on the job and at home. Welfare may be especially important for single working mothers, for whom the burden of multiple roles may be even heavier. The present study assessed levels and predictors of well-being of single and coupled employed mothers in Greece, Portugal and Spain, where welfare support is relatively limited. Results were compared to a parallel study with data from Denmark, Norway and Sweden, where welfare support is relatively comprehensive. Coupled mothers in Scandinavia had significantly lower financial hardship, longer education, higher life satisfaction, more enriching jobs, practical support, financial support and social participation than coupled mothers in the Southern European sample. On the other hand, the Scandinavian coupled mothers had higher levels of work family conflict than coupled mothers in Southern Europe. Single mothers in Scandinavia, compared to single mothers in Southern Europe, had significantly longer education, higher life satisfaction and positive affect, more enriching jobs, confidant support, practical support, financial support and social participation. Level of job stress was the same for all mother groups. All groups differed significantly from each other in level of financial hardship, with Scandinavian coupled mothers being best off, followed by Scandinavian single mothers, Southern European coupled mothers, and Southern European single mothers. The regional differences suggest that single motherhood per se need not be a risk factor for poorer well-being, and that welfare policies may have a protective effect for the mental well-being of single mothers.

    Background: Physical activity (PA) includes muscle activity during exercise, manual work, and leisure time activities including sport. Conflicting results exist regarding health effects of PA that may deteriorate with manual work and elite sports, but improve when performed in moderation in accordance with international guidelines and may additionally enhance well-being and productivity. Methods: In Denmark 15 randomized controlled trials have been conducted, introducing exercise at the workplace enrolling>3500 workers. The interventions lasted from 10 to 52 weeks and offered~1 h weekly supervised exercise during working hours according to the concept of intelligent physical exercise training (IPET) that is based on evidenced sports sciences training principles and tailored to work exposure, employee health status, and physical capacity. Questionnaire surveys and health checks including blood and muscle sampling were performed at baseline and follow-up. The job groups included: office and computer workers, dentists, industrial technicians, cleaning personnel, health care workers, construction workers, and fighter/helicopter pilots. Results: In all job groups significant improvements were documented regarding health outcomes. These were job group specific:neck pain was reduced among office and computer workers, dentists, industrial laboratory technicians, health care workers as well as fighter pilots. Cardio-respiratory fitness—a health risk indicator for cardio-metabolic diseases—was improved among office and computer workers, health care workers, and construction workers. Additionally, other improvements were evidenced such as increased muscle strength and balance control. Importantly, productivity increased with improved muscle strength and decreased body mass index. Conclusion: IPET does enhance health if an exercise program with evidenced efficacy is implemented by expert trainees with support of the employer. Accordingly, in every study group outcomes of

    The grinding properties of abandoned concrete, which consists primarily of hardened cement, limestone aggregate and river sand, are studied. Theoretical models of grinding are used to explain the experimental observation. The results show that 1) The principle disintegration mechanism of hardened cement and river sand is volumetric grinding, although at later stages grinding of cement becomes difficult because of its flaked structure; 2) The limestone grinding process can be divided into two steps. First, volumetric grinding, with an obvious component of surface grinding, followed by primarily surface grinding as the micro-particle content increases; 3) Initially, the principle mechanism of grinding limestone and river sand is volumetric grinding, albeit less efficient grinding than if these components were ground separately, and; 4) After 10 to 20 min of grinding the grinding bottleneck phenomenon appears and after 20 min of grinding the content of micro-particles is large and surface grinding is the main mechanism while the particle size of the mixture is smaller than that of separately ground river sand and cement but bigger than that of separately ground limestone.

    The abandonment of agricultural lands promotes temporal changes both in soil characteristics (i.e., increasing organic matter and other quality indicators) and in plant community (i.e., changing its composition and structure, and increasing the fuel load). As a consequence, we can expect differences in the resilience to fire as succession progresses. The aim of this work is to analyse the capacity of an ecosystem to return to pre-fire conditions as a function of the stage of abandonment of old agricultural lands. The study was carried out in the north of Alicante province (E Spain). In long-term abandoned lands, post-fire modulated plant response, which in turn determined soil crusting, runoff and erosion dynamics. In recently-abandoned lands, the plant community seemed less dependent on ratio to recover. Results show a large increase in soil surface crusting in the short term after the fire and it remained high at medium term in long-abandoned lands colonised by pine forest. Fire scarcely modified runoff and erosion in recently-abandoned lands whereas in forest lands the post-fire values increased by some orders of magnitude and remained highly dependent on rain characteristics in the short and medium term after the fire. The results obtained show evidence of increased vulnerability to fire in long-abandoned lands colonised by pine forests. (Author) 4 refs.

    Excessive ground-water use and saline intrusion to the aquifer led, in less than three decades, to an increase in abandoned agricultural fields at La Costa de Hermosillo, within the Sonoran Desert. Using a chronosequence from years since abandonment, patterns of field succession were developed. Contrary to most desert literature, species replacement was found, both in fields with and without saline intrusion. Seasonal photosynthetic capacity as well as water and nitrogen use efficiencies were different in dominant early and late successional plant species. These ecological findings provided a framework for a general explanation of species dominance and replacement within abandoned agricultural fields in the Sonoran Desert. ?? 2004 Elsevier Ltd.

    Full Text Available The aim of the work is to evaluate the spatial distribution of Hg in the soil-plant system within an area where intense activity of Hg was dominant over a long period. An abandoned metallurgical plant from the 17th-18th centuries was chosen as the study area. It is situated in Almadenejos within the Almadén mining district (Spain that constitutes the largest and most unusual concentration of mercury in the world and has provided a third of the entire world production of mercury (Hg. Nowadays, this study area is covered with cinnabar mine tailings and village habitants use it for livestock. The area has elevated Hg concentrations of natural origin and from human activities. Soil parameters are similar throughout the study area; however, data reveal high variability in total and available Hg concentrations in soils, making it difficult to establish a tendency. Marrubium vulgare L.has been studied due to its high presence in the field plot, and there is no evidence of phenological toxicity. Furthermore, in spite of elevated Hg concentrations, a good biological activity is tested in the soil samples. All these characteristics, spatial variation, high Hg concentration, good biological activity, enhance the peculiarity of the study area for studies involving Hg.

    Full Text Available Physician-patient relationship is unique in some aspects and not-so-unique in other aspects when compared to other human interactions. Until-unless for the sake of health promotional activities, this relationship is almost always conceived in the times of human sufferings and consequently culminated when those sufferings have subsided as well as sought out happiness has ensued/been achieved. However, not all physician-patient relationships follow the normal course and/or meet the natural ends. These abnormal relationships are not inconsequential in terms of numbers and/or their effects (short-term and long term on both patients and physicians. Every country has its own baggage in the wake of why, how and what about these abnormal ends to physician-patient relationships; however, the most common causes are the patients’ inability to pay their medical bills, the conflicting goals of physicians and their patients in regards to patients’ sufferings’ management and finally the behavioral issues (patients’ and/or physicians’ interfering these relationships. Irrespective of any cause, the physicians should never forget that the patient can always discharge their physicians and discontinue their relationship with their physicians without any reason (until unless the physicians deem those patients either incapable/non-consentable to do so and/or potential threat to their own personal safety or other people’s safety. Contrarily, physicians can also discharge patients from their care but cannot abandon these patients (1-3 which mean that physicians have to ensure their discharged patients either are referred to or have sought another physician within appropriate time frame post-relationship-discontinuation.

    2014-04-01

    Grounded in a multistudy framework, we examined the relationship between family-supportive supervisor behaviors, work engagement, and subjective well-being as a contextually dependent mediated process. In Study 1 (N = 310), based on broaden-and-build and conservation of resources theories, we tested the proposed mediated process while controlling for perceived organizational support and perceived managerial effectiveness. We also demonstrated that family-supportive supervisor behaviors are distinguishable from general supervisor behaviors. In Study 2 (N = 1,640), using multigroup structural equation modeling, we validated and extended Study 1 results by examining how the mediated model varied based on 2 contextualizing constructs: (a) dependent care responsibilities and (b) availability of family-friendly benefits. Although the mediational results were contextually dependent, they were not necessarily consistent with hypothesizing based on conservation of resources theory. Practical implications are emphasized in addition to future research directions.

    This paper estimates the short-run causal effect of tumor detection and treatment on psychosocial well-being, work and income. Tumor detection can be considered as a random event, so that we can compare individuals' average outcomes in the year of diagnosis with the year before. We argue for using panel data estimation techniques that enable us to control for observed and unobserved information intrinsic to the individual and time constants. We use data of a national representative panel in the Netherlands that includes health survey information and data on work, education, and income between 2007 and 2012. Our findings show differences in the psychosocial dysfunction of men and women in response to tumor detection and treatment. Women, not men, are decreasingly likely to participate in the labor force as a result of malignant tumor detection, while no significant effects are found on her personal or household income. We also demonstrate that fixed effects panel data models are superior to matching techniques.

  11. "I no longer believe": did Freud abandon the seduction theory?

    Science.gov (United States)

    Ahbel-Rappe, Karin

    2006-01-01

    Recent accounts of the seduction theory and the question of its abandonment have emphasized the continuity of Freud's work before and after the seduction theory, claiming that Freud did not abandon his concern with the event of seduction but rather came to appreciate that an understanding of fantasy was also essential. This claim is challenged. It is shown that Freud did abandon the passionate concerns of his seduction theory for the most part; that he left behind his early interest in reconstructing unconscious infantile incest and focused instead on later, conscious seduction; that he at times clearly reduced apparent paternal incest to fantasy; that he turned away from the phenomenology of incest he had begun to develop; and that he theoretically nullified the value of the difference between real and fantasied seduction. It is also shown that, contrary to a persistent concern in psychoanalytic history, attention to actual seduction need not detract from the essential psychoanalytic concern with fantasy and infantile sexuality. Thinking about incest specifically illuminates the capacity for fantasizing, the core of the Freudian psyche. In this way the intuition of the seduction theory that there is something of distinctive psychoanalytic significance about incest finds support.

    2010-01-01

    Full Text Available It is since mythology to classical ages in Greece, since Medieval Ages to the end of the 19th century in Smyrna and in Athens, that history indicates the abandonment of the infants as a phenomenon always existing. A time flashback and the research of the phenomenon through the historic examples contribute unequivocally to the remonstrance of the social facts in each era.Aim: The aim of this study was to critically review all the historical data and the evidence from the international and Greek literature and to explore the factors that are accountable for to the infant’s abandonment and especially in Greece.Method: A critical literature search was performed using of MEDLINE and CINAHL (1990-2008 databases. The literature review referred to historical data related to the care of the abandoned infants since ancient Greek times.Conclusion: The literature review leads to the conclusion that the detection of the historical sources combines a “mosaic” which reflects the multiple needs of the Greek society, with target to encounter the infant abandonment. The ways used each time in order the phenomenon to be faced, not rarely were doubted. Still they stand as the salutary solutions for the abandoned infants and they are explained and established through the social background of each era and through the needs serviced each time.

    Agricultural land abandonment is recognized as a major environmental threat in Europe, being particularly pronounced in south-eastern Europe, where knowledge on its effects is limited. Taking the Balkan Peninsula as a case study, we investigated agricultural abandonment impact on passerine communities at regional level. We set up a standard methodology for site selection (70 sites) and data collection, along a well-defined forest-encroachment gradient that reflects land abandonment in four countries: Albania, Bulgaria, Croatia and Greece. Regardless the different socio-economic and political histories in the Balkans that led to diverse land abandonment patterns in space and time, rural abandonment had a consistent negative effect on bird communities, while regional-level analysis revealed patterns that were hidden at local level. The general trends were an increase of forest-dwelling bird species at the expense of farmland birds, the decline of overall bird species richness, as well as the decline of Species of European Conservation Concern (SPECs) richness and abundance. Many farmland bird species declined with land abandonment, whereas few forest species benefited from the process. In conclusion, our results support CAP towards hampering rural land abandonment and preserving semi-open rural mosaics in remote upland areas, using a suite of management measures carefully tailored to local needs. The maintenance of traditional rural landscapes should be prioritized in the Balkans, through the timely identification of HNV farmland that is most prone to abandonment. We also suggest that coordinated transnational research is needed, for a better assessment of conservation options in remote rural landscapes at European scale, including the enhancement of wild grazers' populations as an alternative in areas where traditional land management is rather unlikely to be re-established.

    2002-01-01

    Microbiological evaluation of sandy grassland soils from two different stages of secondary succession on abandoned fields (4 and 8 years old fallow) was carried out as a part of research focused on restoration of semi-natural vegetation communities in Kiskunság National Park in Hungary. There was an apparent total N and organic C enrichment, stimulation of microbial growth and microbial community structure change on fields abandoned by agricultural practice (small family farm) in comparison with native undisturbed grassland. A successional trend of the microbial community was found after 4 and 8 years of fallow-lying soil. It consisted in a shift of r-survival strategy to more efficient C economy, in a decrease of specific respiration and metabolic activity, forced accumulation of storage bacterial compounds and increased fungal distribution. The composition of microbial phospholipid fatty acids mixture of soils abandoned at various times was significantly different.

    Infant abandonment and infanticide are poorly understood in Malaysia. The information available in the public arena comes predominantly from anecdotal sources. The aim of this study was to describe the prevalence and characteristics of infanticide and illegal infant abandonment in Malaysia and to estimate annual rates for the most recent decade. Summaries of data about infanticide and illegal infant abandonment were gathered from police records; the annual number of live births was ascertained from the national registry. The estimated inferred infanticide rates for Malaysia were compared with the infanticide rates among countries of very high, high, medium, and low rankings on the Human Development, Gender Inequality, and Gini indices. From 1999 to 2011, 1,069 cases of illegal infant abandonment were recorded and 1,147 people were arrested as suspected perpetrators. The estimated inferred infanticide rate fluctuated between 4.82 and 9.11 per 100,000 live births, a moderate rate relative to the infanticide rates of other countries. There are substantial missing data, with details undocumented for about 78-87% of cases and suspected perpetrators. Of the documented cases, it appeared that more boys than girls were victims and that suspected perpetrators were predominantly Malays who were women, usually mothers of the victim; the possibility of arrest bias must be acknowledged. Economic and social inequality, particularly gender inequality, might contribute to the phenomena of infanticide and abandonment. Strategies to reduce rates of infanticide and illegal infant abandonment in Malaysia will require strengthening of the surveillance system and attention to the gender-based inequalities that underpin human development.

  18. Abandonment, Ecological Assembly and Public Health Risks in Counter-Urbanizing Cities

    Directory of Open Access Journals (Sweden)

    Alexandra Gulachenski

    2016-05-01

    Full Text Available Urban landscapes can be transformed by widespread abandonment from population and economic decline. Ecological assembly, sometimes referred to as “greening”, following abandonment can yield valuable ecosystem services, but also can pose a risk to public health. Abandonment can elevate zoonotic vector-borne disease risk by favoring the hyperabundance of commensal pests and pathogen vectors. Though greater biodiversity in abandoned areas can potentially dilute vector-borne pathogen transmission, “greening” can elevate transmission risk by increasing movement of pathogen vectors between fragmented areas and by giving rise to novel human-wildlife interfaces. Idled and derelict infrastructure can further elevate disease risk from vector-borne and water-borne pathogens, which can build up in stagnant and unprotected water that maintenance and routine use of delivery or sanitation systems would otherwise eliminate. Thus, framing “greening” as inherently positive could result in policies and actions that unintentionally exacerbate inequalities by elevating risks rather than delivering benefits. As counter-urbanism is neither a minor pattern of urban development, nor a short-term departure from urban growth, homeowner and municipal management of abandoned areas should account for potential hazards to reduce health risks. Further socioecological assessments of public health risks following abandonment could better ensure the resilience and well-being of communities in shrinking cities.

    It is well known that some sinkholes or subsidence take place from time to time in the areas where abandoned room and pillar type mines exist. The author has been involved with the stability of abandoned mines beneath urbanized residential areas in Tokai region and there is a great concern about the stability of these abandoned mines during large earthquakes as well as in the long term. The 2003 Miyagi Hokubu and 2011 Great East Japan earthquakes caused great damage to abandoned mines and resulted in many collapses. The author presents the effect of the depth and groundwater on the formation of sinkholes or ground subsidence associated with abandoned room and pillar lignite mines under static and dynamic conditions and discusses the implications on the areas above abandoned lignite mines in this paper.

  5. Exploring the Dynamic Mechanisms of Farmland Abandonment Based on a Spatially Explicit Economic Model for Environmental Sustainability: A Case Study in Jiangxi Province, China

    Directory of Open Access Journals (Sweden)

    Hualin Xie

    2014-03-01

    Full Text Available Farmland abandonment has important impacts on biodiversity and ecosystem recovery, as well as food security and rural sustainable development. Due to rapid urbanization and industrialization, farmland abandonment has become an increasingly important problem in many countries, particularly in China. To promote sustainable land-use management and environmental sustainability, it is important to understand the socioeconomic causes and spatial patterns of farmland abandonment. In this study, we explored the dynamic mechanisms of farmland abandonment in Jiangxi province of China using a spatially explicit economical model. The results show that the variables associated with the agricultural products yield are significantly correlated with farmland abandonment. The increasing opportunity cost of farming labor is the main factor in farmland abandonment in conjunction with a rural labor shortage due to rural-to-urban population migration and regional industrialization. Farmlands are more likely to be abandoned in areas located far from the villages and towns due to higher transportation costs. Additionally, farmers with more land but lower net income are more likely to abandon poor-quality farmland. Our results support the hypothesis that farmland abandonment takes place in locations in which the costs of cultivation are high and the potential crop yield is low. In addition, our study also demonstrates that a spatially explicit economic model is necessary to distinguish between the main driving forces of farmland abandonment. Policy implications are also provided for potential future policy decisions.

  11. The Oedipus complex revisited: Oedipus abandoned, Oedipus adopted.

    Science.gov (United States)

    Quinodoz, D

    1999-02-01

    The author considers that the Oedipus of Sophocles' drama, who kills his biological father and marries his biological mother, is an illustration of the failure to work through the complex named after him. She draws attention to the contrast between the obscurity that surrounds the hero's adoptive parents and the notoriety of their biological counterparts arguing that the former are equally important in the universal oedipal fantasy. In her view the fact that Oedipus has two sets of parents--abandoning and adopting respectively--is significant in that the resulting dichotomisation of the parental imago enables him seemingly to avoid a conflict of ambivalence in relation to a single object. The author further contends that the plague of Thebes represents the symptomatic return of repressed or disavowed aggression. Three clinical examples reveal the parental imago's division to be an unconscious defence against oedipal anxieties and the sense of solitude vis-à-vis the intimacy of the parental couple. The working through of the Oedipus complex is stated to require the synthesis of love and hate and of the abandoning and adoptive aspects of the parents whereby the formerly sadistic superego becomes protective. The author also argues that a useful distinction can be made between splitting and dichotomisation.

  14. Hospital Qualities Related to Return to Work from Occupational Injury after Controlling for Injury Severity as Well as Occupational Characteristics

    Science.gov (United States)

    2016-01-01

    We examined associations between hospital quality in the workers’ compensation system and injured patients’ return to work after controlling for injury severity, occupational factors, and demographic factors. Return to work data of injured workers were constructed from 2 datasets: 23,392 patients injured in 2009–2011 from the Korea Workers’ Compensation & Welfare Service and return to work data from Korea Employment Information Services. After de-identifying the data, quality scores were matched for each hospital that cared for injured patients. Injury severity was measured by Abbreviated Injury Scales. Relative risk and 95% confidence interval were calculated using log binomial regression models. After adjusting for age, sex, injury severity, occupation, factory size, city, and hospital type, the relative risk (95% confidence interval) for the total score was 1.04 (1.02–1.06), 1.06 (1.04–1.09), and 1.07 (1.05–1.10) in the 2nd, 3rd, and 4th quartiles, respectively, compared to the 1st quartile.

    We examined associations between hospital quality in the workers' compensation system and injured patients' return to work after controlling for injury severity, occupational factors, and demographic factors. Return to work data of injured workers were constructed from 2 datasets: 23,392 patients injured in 2009-2011 from the Korea Workers' Compensation & Welfare Service and return to work data from Korea Employment Information Services. After de-identifying the data, quality scores were matched for each hospital that cared for injured patients. Injury severity was measured by Abbreviated Injury Scales. Relative risk and 95% confidence interval were calculated using log binomial regression models. After adjusting for age, sex, injury severity, occupation, factory size, city, and hospital type, the relative risk (95% confidence interval) for the total score was 1.04 (1.02-1.06), 1.06 (1.04-1.09), and 1.07 (1.05-1.10) in the 2(nd), 3(rd), and 4(th) quartiles, respectively, compared to the 1(st) quartile. The RR (95% CI) in the 2(nd), 3(rd), and 4(th) quartiles was 1.05 (1.02-1.07), 1.05 (1.02-1.08), and 1.06 (1.04-1.09) for the process score; and 1.02 (1.01-1.04), 1.05 (1.03-1.07), and 1.06 (1.04-1.09) for the outcome score compared to the 1(st) quartile score, respectively. In conclusion, our study design with blinded merge methods shows that total, process, and outcome qualities are related to the return to work of injured workers after controlling for other factors.

    Heavy workloads have been central to the discussion of well-being. However, fluctuations in workloads have received sparse attention, even though transient and routine levels of workloads may have independent effects on well-being. The article assesses this, particularly focusing on the effort-recovery model of the workload/well-being relationship in which work-nonwork interference mediates this relationship. Using data from a weekly diary study of freelance or portfolio workers, multilevel analyses showed that both routine and transient levels of work to nonwork interference mediated the job demands-calmness relationship. Work to nonwork interference also negatively mediated the hours worked-calmness relationship, but the direct relationship between hours worked and calmness was a positive one so the mediating effect reduced this positive effect. In the case of enthusiasm, which was a second measure of well-being, there were no mediating effects but both routine and nonroutine levels of job demands and transient levels of hours worked were related to it. The study highlights the value of introducing the temporal dimension into the study of the work-nonwork interface, and the diversity of relationships that occur across different dimensions of workload and well-being.

    Reports an error in "Let It Be and Keep on Going! Acceptance and Daily Occupational Well-Being in Relation to Negative Work Events" by Katharina Kuba and Susanne Scheibe (Journal of Occupational Health Psychology, Advanced Online Publication, Feb 25, 2016, np). In the article, there were errors in the Participants subsection in the Method section. The last three sentences should read "Job tenure ranged from less than 1 year to 32 years, with an average of 8.83 years (SD 7.80). Participants interacted with clients on average 5.44 hr a day (SD 2.41). The mean working time was 7.36 hr per day (SD 1.91)." (The following abstract of the original article appeared in record 2016-09702-001.) Negative work events can diminish daily occupational well-being, yet the degree to which they do so depends on the way in which people deal with their emotions. The aim of the current study was to examine the role of acceptance in the link between daily negative work events and occupational well-being. We hypothesized that acceptance would be associated with better daily occupational well-being, operationalized as low end-of-day negative emotions and fatigue, and high work engagement. Furthermore, we predicted that acceptance would buffer the adverse impact of negative work events on daily well-being. A microlongitudinal study across 10 work days was carried out with 92 employees of the health care sector, yielding a total of 832 daily observations. As expected, acceptance was associated with lower end-of-day negative emotions and fatigue (though there was no association with work engagement) across the 10-day period. Furthermore, acceptance moderated the effect of negative event occurrence on daily well-being: Highly accepting employees experienced less increase in negative emotions and less reduction in work engagement (though comparable end-of-day fatigue) on days with negative work events, relative to days without negative work events, than did less accepting employees. These

    Although an increasing number of studies on adults have indicated that working memory (WM) contributes to the ability to understand the mental states of others (i.e., theory of mind), the detailed mechanism by which WM contributes to successful reasoning has not previously been revealed. This study shows that WM modulates the degree of attribution of one's own knowledge to others' mental states. Participants were asked to read a story twice (Experiment 2) or as carefully as possible (Experiment 3) and to estimate the probability percentages of possible choices for a naive protagonist's behavior. The participants were then asked to maintain either a two- or seven-letter alphabet string (i.e., a light or heavy WM load, respectively) during the probability estimation but not during the story comprehension. The results showed that compared to the participants with a light WM load, those with a heavy WM load estimated a significantly higher probability of the choice indicating that the protagonist would behave on the basis of a fact that the participants knew but the protagonist did not. This result indicates that WM moderates the extent to which adults attribute their own knowledge to others' mental states. The role of WM in theory of mind and in heuristic strategy for making probability judgments was then discussed.

Adopting a personal survey method data was collected from 373 managers (both males and females) from the public and private sectors representing manufacturing and service industry in India. The study bridges the knowledge gap by operationalizing the construct of perceived gender equity and studying its role in the work engagement and employee well-being. Conceptualization of the well-being in an unconventional way covering both the positive and the negative aspects extends the understanding of the emerging concept of well-being. It has practical implications for talent management and work engagement besides promoting gender equity at the workplace for employee well-being. It opens vistas for the gender based theory and cross cultural research on gender equity.

    Li, Andrew; Shaffer, Jonathan; Bagger, Jessica

    2015-01-01

    We draw on the cross-domain model of work-family conflict and conservation of resources theory to examine the relationship between disability caregiving demands and the psychological well-being of employed caregivers. Using a sample of employed disability caregivers from a national survey, we found that the relationship between caregiving demands and family-to-work conflict was stronger when employees experienced high levels of strain from family. Additionally, we found high levels of family to-work conflict were subsequently associated with decreases in life satisfaction and increases in depression, but only when perceived supervisor support was low. Overall, our findings suggest an indirect relationship between caregiving demands and psychological well-being that is mediated by family-to-work conflict and is conditional on family strain and perceived supervisor support. The theoretical and practical implications of these findings are discussed.

  8. DETERMINANTS OF CULTIVATED LAND ABANDONMENT IN THE HILLS OF WESTERN NEPAL

    Directory of Open Access Journals (Sweden)

    CHHABI LAL CHIDI

    2016-06-01

    Full Text Available Determinants of Cultivated Land Abandonment in the Hills of Western Nepal. This paper deals with the change in agricultural land use pattern in the Andhi khola watershed of Syangja district, Western hills of Nepal, where the population has decreased for the last two decades, which is being the main cause of the agricultural land abandonment, resulting into increase in the fallow lands and vegetation wilderness. This phenomenon has also occurred elsewhere in other parts of the hill region of Nepal, resulting in labor deficit in the agriculture activities. Landsat images of 1999 and 2014 have been used for land use change. Topographic map has been used as the map source. DEM was generated from the contours of the topographic map to derive altitude, slope gradient and slope aspect. The Geographically Weighted Regression Model has been used for prediction of abandonment of cultivated land by location across the study region as well as to identify local variability of the strength of the explanatory variables. Changes in population and altitudinal variation are found as significant factors of agricultural land abandonment. Besides, slope gradient and slope aspect are also found as determining factors. Combined effects of accessibility, landform, land suitability, and irrigation facility on change in agricultural land use pattern are the result of greater strength of the altitudinal variation effect. The lowland areas together with easy access to market and better irrigation facilities are found suitable for the cultivation of a variety of crops. Therefore, these areas have less land abandonment as compared to the highland areas, which were used by local residents for cultivation, though marginal. It is concluded that most of the previously cultivated marginal land in the hills has released population pressure, resulting into land abandonment, which is further accelerated by institutional weaknesses.

    In 2002, a child was abandoned in a Burger King restaurant in Amsterdam by a Chinese woman, who hoped that the baby would be picked up by someone able to give the child a better life. She was convicted for child abandonment and imprisoned. Whereas some forms of child abandonment are criminalised, others are socially accepted and not even on the ethics agenda. This paper is an invitation to reflect on the inconsistency in the ways in which we prosecute, punish or try to correct some forms of child abandonment and yet make allowances for others.

    The Hanford Site contains about 2200 wells constructed from pre-Hanford Works days to the present. As of June 1977, about 1900 wells still exist, and about 850 of these existing wells were drilled to the ground-water table. About 700 of these wells (including about 24 farm wells) still contain water. The others have become dry through infiltration of sediments or a general lowering of the water table in their vicinity. This report, providing the most complete documentation of wells in and adjacent to the Hanford Site, supersedes all previous compilations of Hanford wells.

    This study evaluated the effectiveness of a computer-based stress management training (SMT) program in improving employees' psychological well-being and work performance. A total of 12 work units (N=263) were randomly assigned to either an intervention group (8 work units, n=142) or to a wait-list control group (4 work units, n=121). All participants were requested to answer online questionnaires assessing psychological well-being as a primary outcome, and coping style, social support, and knowledge about stress management as secondary outcomes at baseline (T0), immediately after the intervention (T1), and 2 months after the intervention (T2). The group × time interaction was tested using a mixed-model repeated measures ANOVA. Results showed a group × time interaction for "knowledge about stress management" in the entire sample. Among participants who had more than 3 d of training, a significant group × time interaction was observed for "problem-solving" and "avoidance and suppression" as well as "knowledge about stress management." Our computer-based stress management program was effective for improving knowledge about stress management. It was also effective for improving coping skills in instances where participants had enough time (at least 3 d) to complete all sessions.

    Full Text Available Abstract Background It is well-known that health care workers in today’s general hospitals have to deal with high levels of job demands, which could have negative effects on their health, well-being, and job performance. A way to reduce job-related stress reactions and to optimize positive work-related outcomes is to raise the level of specific job resources and opportunities to recover from work. However, the question remains how to translate the optimization of the balance between job demands, job resources, and recovery opportunities into effective workplace interventions. The aim of the DISCovery project is to develop and implement tailored work-oriented interventions to improve health, well-being, and performance of health care personnel. Methods/Design A quasi-experimental field study with a non-equivalent control group pretest-posttest design will be conducted in a top general hospital. Four existing organizational departments will provide both an intervention and a comparison group. Two types of research methods are used: (1 a longitudinal web-based survey study, and (2 a longitudinal daily diary study. After base-line measures of both methods, existing and yet to be developed interventions will be implemented within the experimental groups. Follow-up measurements will be taken one and two years after the base-line measures to analyze short-term and long-term effects of the interventions. Additionally, a process evaluation and a cost-effectiveness analysis will be carried out. Discussion The DISCovery project fulfills a strong need for theory-driven and scientifically well-performed research on job stress and performance interventions. It will provide insight into (1 how a balance between job demands, job resources, and recovery from work can be optimized, (2 the short-term and long-term effects of tailored work-oriented effects, and (3 indicators for successful or unsuccessful implementation of interventions.

  16. A 12-year cavern abandonment test

    Brouard B.

    2010-06-01

    Full Text Available In 1997-1998, an abandonment test was performed in a 950-m deep, 8000-m3 salt cavern operated by GDF SUEZ at Etrez, France. In this relatively small brine-filled cavern, which had been kept idle for 15 years before the test, thermal equilibrium was reached. A special system was designed to monitor leaks, which proved to be exceedingly small. In these conditions, brine permeation and cavern creep closure are the only factors to play significant roles in pressure evolution. This test strongly suggested that obtaining an equilibrium pressure such that the effects of these two factors were exactly equal would be reached in the long term. Four years later, pressure monitoring in the closed cavern resumed. Pressure evolution during the 2002-2009 period confirmed that cavern brine pressure will remain constant and significantly smaller than geostatic pressure in the long term, precluding any risk of fracturing and brine seepage to the overburden layers.

  5. Meanings of Consumption and Abandonment: Understanding Smoking Cessation Symbolism

    Directory of Open Access Journals (Sweden)

    Maribel Carvalho Suarez

    2014-04-01

    Full Text Available In consumption studies, very little attention has been focused on investigating abandonment and, more specifically, its symbolic dimension. The present study aims to investigate how meanings are created and negotiated through the abandonment of cigarettes. This study used a qualitative methodology to collect and analyze the data generated by one-on-one semi-structured in-depth interviews with 15 Brazilian ex-smokers. Results suggest that abandonment of cigarettes can be offered as a connection, gift, or sacrifice that makes relations special and even magical. As regards abandonment, the present study evidences the interactions and movements of positive and negative meanings related to the consumption and non-consumption of a category. The study proposes a framework that highlights the cooling, decontamination, reinforcement and defensive symbolical movements, thus constructing a tool for analyzing abandonment, offering possible paths of intervention for organizations that are interested in this issue.

With increasing neglect, abandonment, and rising conversions of centuries old rice fields into other uses, ecological and environmental consequences of these transitions are becoming progressively clear. Field observations in Sri Lanka's central highlands suggest that small shifts in rice to non-rice land uses in headwater watersheds can have a domino effect on the productivity and viability of rice fields and other ecological systems downstream by inflicting groundwater recharge reductions, lowering groundwater yields, and causing other hydrological changes. Preliminary analysis shows that although rice itself is a very water intensive crop, the presence of rain-fed upland rice-fields is hugely beneficial to the watersheds they reside. In particular, water benefits of rice appear to be derived from ponded conditions (3-5 inches of standing water) in which rice is grown, and the contribution rice fields makes to enhance water retention and storage capacity of their watersheds during the monsoon season that coincide with the cropping season. In the absence of well managed rice-fields, hilly upland landscapes produce more runoff and retain little rainwater during the wet season. Furthermore, after centuries of intensive use, much of South Asia's rice fields are nutrient poor and minimally productive without fertilizer applications and other interventions. Consequently, when abandoned, soil erosion and other impacts that affect aquatic ecosystems and watershed health also emerge. Despite these multiple concerns however, little research is currently done to better understand the environmental significance of rice cultivations that are a dominant land-use in many South Asian landscapes. The aim of this presentation is to stir interest among the scientific community to engage more broadly in rice, water, and environmental change research in the face of new economic realities in

    CO2CARE is an EU funded project within FP7-research, which started in January 2011 with a funding period of three years. The project objectives will be achieved through an international consortium consisting of 23 partners from Europe, USA, Canada, Japan, and Australia, belonging to universities, research institutes, and energy companies. According to the EC Guidance Document 3, the lifetime of a CO2 storage site can be generally subdivided into 6 phases: 1. assessment, 2. characterisation, 3. development, 4. operation, 5. post-closure/pre-transfer, and 6. post transfer. CO2CARE deals with phases 5 and 6. The main goals of the project are closely linked to the three high-level requirements of the EU Directive 2009/31/EC, Article 18 for CO2 storage which are: (i) absence of any detectable leakage, (ii) conformity of actual behaviour of the injected CO2 with the modelled behaviour, and (iii) the storage site is evolving towards a situation of long-term stability. These criteria have to be fulfilled prior to subsequent transfer of responsibility to the competent authorities, typically 20 or 30 years after site closure. CO2CARE aims to formulate robust procedures for site abandonment which will meet the regulatory requirements and ensure long-term integrity of the storage complex. We present key results from the first year of the project via a report on international regulatory requirements on CO2 geological storage and site abandonment that includes a general overview on the current state-of-the art in abandonment methodologies in the oil and gas industry worldwide. Due to the long time-frames involved in CO2 storage (in the range of several thousands of years), the behaviour of a system with respect to, for example, long-term well stability can be demonstrated only by using long-term predictive modelling tools to study potential leakage pathways. Trapping mechanisms for CO2 are of high interest concerning a quantitative estimation of physically captured, capillary

    The associations of work stress, types of work and gender-role orientation with psychological well-being and sickness absence were investigated in a questionnaire survey of 588 male and female nurses and 387 male and female accountants. We hypothesised that health might be impaired among women working in the male-dominated occupation (accountancy), and men in the female-dominated occupation (nursing), but that effects might be moderated by job strain (perceptions of high demand and low control), work and home hassles, and traditional male (instrumentality) and female (expressivity) psychological characteristics. Responses were analysed from 172 female and 61 male nurses, and from 53 female and 81 male commercial accountants. Female accountants were more likely than other groups to have high anxiety scores on the Hospital Anxiety and Depression Scales, while male nurses had the highest rates of sickness absence. Male nurses and female accountants also reported more work-related hassles than did female nurses and male accountants. Men and women in the same occupation did not differ in job strain or job social support, but nurses reported greater job strain than accountants, due to higher ratings of demands and lower skill utilisation. After adjusting for age, sex, occupation, paid work hours and a measure of social desirability bias, risk of elevated anxiety was independently associated with higher job strain, lower job social support, more work hassles, more domestic responsibility, lower instrumentality and higher expressivity. The association between sex and anxiety was no longer significant after instrumentality had been entered into the regression model. Sickness absence of more than three days over the past 12 months was independently associated with higher job strain, more work hassles, lower instrumentality and higher expressivity. The results suggest that when men and women occupy jobs in which they are in the cultural and numerical minority, there may be

    After about seven years of pumping more than 30 million barrels of oil from the two relatively small fields of Cohasset-Panuke, the fields' five wells ran dry, and operations were subsequently shut down. The latest development is that EnCana Corporation, and Nova Scotia Resources Limited, current owners of the venture, have decided to remove from the Scotian Shelf the project's two huge platforms and all their attached subsea equipment, ultimately to be scrapped or resold. Cohasset-Panuke were first developed by LASMO Nova Scotia Limited in 1990, and bought out by Pan-Canadian in the mid-1990s. Since then Pan-Canadian merged with Alberta Energy to become EnCana. Three of the five wells produced crude; the other two were directionally drilled wells which revealed commercially-viable quantities of deposits in the field. One of these wells led to the discovery of Deep Panuke, lying almost directly beneath Cohasset-Panuke, which contains one trillion cubic feet of sour natural gas. A $35-million loan guarantee will be made available to the owners by the Canada-Nova Scotia Offshore Petroleum Board once a managing contractor for the decommissioning work is selected. Development of Deep Panuke is expected to be delayed until EnCana is satisfied that the project is financially justifiable.

  12. Nurses' attitudes and knowledge of their roles in newborn abandonment.

    2003-01-01

    The practice of abandoning newborns shortly after birth has always existed. Occurring in primitive and contemporary societies, the motivations for newborn abandonment are varied and dependent upon the social norms of a specific geographic region at a given point in time. Because the desire to abandon an infant has had no support system in American society, such unwanted infants have been abandoned in a manner leading to their deaths. In response, many states have passed safe-haven legislation to save the lives of unwanted newborns. The laws typically specify a mother's ability to "abandon" her child to a medical service provider. However, judgmental attitudes and a lack of accurate information may impede a health care provider's ability to carry out a safe-haven law. The study described here examines a sample of nurses in a state with a safe-haven law. The study revealed no significant correlation between a nurse's knowledge, attitude, and self-perception of preparedness to manage a newborn abandonment event. owever, the outcomes highlight the negative attitudes and lack of knowledge many nurses possess regarding newborn abandonment and the women who commit this act. Educational programs for all health care providers and the community are essential to the efficacy of the legislation that currently exists. Continued multidisciplinary strategizing and general awareness are needed to serve as catalysts to build supports for unwanted newborns and their safe assimilation into the community.

The pH of the topsoil was higher in the S-sequence, and correlated significantly negatively with the age of abandonment in both sequences (r=-0.893; p=0.01 in S, and r=-0.739; p=0.05 in SW). TOC stocks of the top 6 cm soil layers were higher in the S-sequence (1.82±0.71 kg m-2) than in the SW-sequence (0.95 ± 0.49 kg m-2), and correlated significantly positively with the duration of self-restoration. When calculated for the whole profile, TOC stocks were similar in both S- and SW-sequences (S: 8.21±3.31 kg m-2; SW: 8.24±6.01 kg m-2). The TOC accumulation rates of the top 6 cm soil layers exhibited 18.9±10.0 g C m-2y-1 in the S and 7.0±4.2 g C m-2y-1 in the SW-sequence. Sites with the same age of abandonment developed to different vegetation and had different soil features in both chronosequences, indicating that duration of self-restoration is only one of the directive factors in soil development and carbon sequestration processes after abandonment of viticulture on Tokaj Nagy-Hill, which was significantly affected by lithology, slope steepness and exposition as well.

  15. Robust Abandoned Object Detection Using Dual Foregrounds

    2007-11-01

    Full Text Available As an alternative to the tracking-based approaches that heavily depend on accurate detection of moving objects, which often fail for crowded scenarios, we present a pixelwise method that employs dual foregrounds to extract temporally static image regions. Depending on the application, these regions indicate objects that do not constitute the original background but were brought into the scene at a subsequent time, such as abandoned and removed items, illegally parked vehicles. We construct separate long- and short-term backgrounds that are implemented as pixelwise multivariate Gaussian models. Background parameters are adapted online using a Bayesian update mechanism imposed at different learning rates. By comparing each frame with these models, we estimate two foregrounds. We infer an evidence score at each pixel by applying a set of hypotheses on the foreground responses, and then aggregate the evidence in time to provide temporal consistency. Unlike optical flow-based approaches that smear boundaries, our method can accurately segment out objects even if they are fully occluded. It does not require on-site training to compensate for particular imaging conditions. While having a low-computational load, it readily lends itself to parallelization if further speed improvement is necessary.

    The aim of this research on 143 workers of the ENEA area in Bologna, has been to survey the degree of well-being perceived and expressed by these workers with respect to different factors of the work environment. This study follows some training/information seminars on environment, health and safety organized in ENEA by Occupational Medicine Group to comply with Leg. Decr. 626/94. In a multidisciplinary approach the health idea has been interpreted not as lack of illness but as pursuit and preservation of the well-being in the work environment. For this purpose, also the involvement and participation of the workers seem to be very useful for subjective reports about individual task, equipment, interfaces, workplace and work organization. In this research, we have adopted an ergonomic checklist based on guiding principles to be applied to the design of optimal working conditions with regard to human well-being, safety and health (see UNI ENV 26385, 1991). Data processing and analysis have requested occupational medicine, ergonomics and statistics competencies. [Italian] La ricerca condotta su un campione ENEA di 143 dipendenti dell'area bolognese ha inteso verificare il grado di benessere percepito ed espresso dai lavoratori in rapporto alle diverse variabili presenti nel contesto lavorativo. Tale indagine e' stata preceduta da specifici seminari di formazione/informazione su ambiente, salute e sicurezza, organizzati a cura della Medicina del Lavoro di Bologna presso le sedi ENEA, a seguito delle disposizioni contenute nel D.Lvo. 626/94. In un'ottica multidisciplinare, il concetto di salute e' stato interpretato non tanto come assenza di malattia quanto come ricerca e mantenimento del benessere lavorativo e, per raggiungere questo scopo, sembra essere molto utile anche il diretto coinvolgimento e la partecipazione dei lavoratori per valutazioni soggettive sulle mansioni assegnate, le attrezzature, le interfacce, la postazione di lavoro e l

    This study aimed at analyzing the reasons that patients co-infected with tuberculosis and HIV leave the treatment of tuberculosis and to know the conduct of the health team toward that abandonment. The study, using a qualitative approach, performed semi-structured interviews on 45 professionals working at a referral health center in Pará state. Two units emerged based on the thematic analysis: patient-associated factors that make TB treatment adherence difficult; and service-associated factors that contribute to treatment abandonment. It was found that, in terms of the patients, that their low socioeconomic condition was the most common factor that led to abandonment. Other factors that led to this outcome included the adverse drug effects, the use of illegal drugs, and poor personal motivation. Regarding the service, issues related to the physical structure, working process organization and accessibility were also relevant to their non-adherence. Results show there is a need to change the practices performed at the health care services.

    As a part of the license application, according to the nuclear activities act, for a final repository for spent nuclear fuel at Forsmark, the Swedish Nuclear Fuel and Waste Management Company (SKB) has undertaken a series of groundwater flow modelling studies. These represent time periods with different hydraulic conditions and the simulations carried out contribute to the overall evaluation of the repository design and long-term radiological safety. The modelling study presented here serves as an input for analyses of so-called future human actions that may affect the repository. The objective of the work was to investigate the hydraulic influence of an abandoned partially open repository. The intention was to illustrate a pessimistic scenario of the effect of open tunnels in comparison to the reference closure of the repository. The effects of open tunnels were studied for two situations with different boundary conditions: A 'temperate' case with present-day boundary conditions and a generic future 'glacial' case with an ice sheet covering the repository. The results were summarized in the form of analyses of flow in and out from open tunnels, the effect on hydraulic head and flow in the surrounding rock volume, and transport performance measures of flow paths from the repository to surface

    The decommissioning and abandonment of platforms and pipelines are big challenges for the pipeline industry. This paper presents a review of the decommissioning and abandonment processes based on a study case, the Rabon Grande pipeline system. First, the applicable international codes, standards and regulations associated with the decommissioning of pipelines are discussed. Next, this paper presents a review of the decommissioning and abandonment options and considerations available for the study case. The Rabon Grande pipeline system, which was shut down and isolated in 1990 pending decommissioning, is used as an example of applying decommissioning and abandonment best practice and establishing a realistic scope of work. A decommissioning plan is developed in light of these previous studies, followed by an environmental impact assessment. It is found that contrary to what was done in the case of the Rabon Grande pipeline, when a pipeline is to be shutdown, the best practice methodology is to temporally or fully decommission the system as soon as possible.

  3. New perspectives on a 140-year legacy of mining and abandoned mine cleanup in the San Juan Mountains, Colorado

    2016-01-01

    The Gold King mine water release that occurred on 5 August 2015 near the historical mining community of Silverton, Colorado, highlights the environmental legacy that abandoned mines have on the environment. During reclamation efforts, a breach of collapsed workings at the Gold King mine sent 3 million gallons of acidic and metal-rich mine water into the upper Animas River, a tributary to the Colorado River basin. The Gold King mine is located in the scenic, western San Juan Mountains, a region renowned for its volcano-tectonic and gold-silver-base metal mineralization history. Prior to mining, acidic drainage from hydrothermally altered areas was a major source of metals and acidity to streams, and it continues to be so. In addition to abandoned hard rock metal mines, uranium mine waste poses a long-term storage and immobilization challenge in this area. Uranium resources are mined in the Colorado Plateau, which borders the San Juan Mountains on the west. Uranium processing and repository sites along the Animas River near Durango, Colorado, are a prime example of how the legacy of mining must be managed for the health and well-being of future generations. The San Juan Mountains are part of a geoenvironmental nexus where geology, mining, agriculture, recreation, and community issues converge. This trip will explore the geology, mining, and mine cleanup history in which a community-driven, watershed-based stakeholder process is an integral part. Research tools and historical data useful for understanding complex watersheds impacted by natural sources of metals and acidity overprinted by mining will also be discussed.

    In the present study we contrast materialistic (i.e., income and economic inequality) and psychosocial (i.e., social circumstances) pathway perspectives on whether volunteering while being unemployed mitigates the well-documented negative effects of unemployment on health, health behaviors, and well-being. We test our hypotheses using data from the 2010 and 2012 waves of the Swedish Longitudinal Occupational Study of Health (SLOSH; n = 717). This is a nationally representative, longitudinal, cohort survey. We compared groups of individuals who were (a) unemployed and volunteering during both SLOSH waves (n = 58), (b) unemployed and not volunteering during both SLOSH waves (n = 194), (c) employed and volunteering during both SLOSH waves (n = 139), and (d) employed and not volunteering during both SLOSH waves (n = 326). Conducting a path analysis in Mplus, we examined the interaction effects between labor market status (i.e., employed or unemployed) and voluntary work (i.e., volunteering or not) when predicting changes in health, health behaviors, and psychological well-being. Our results indicate that volunteering during unemployment significantly decreased the likelihood to smoke, the amount of cigarettes smoked, the likelihood of consuming alcohol, and the likelihood of being diagnosed with hypertension. These results support a psychosocial pathway perspective. For all other indicators no such buffering interaction effect was obtained, thereby supporting a materialistic pathway perspective. Nevertheless, for some indicators, volunteering was found to be beneficial for both the unemployed and employed. Consequently, integrating both perspectives might offer a better explanation for the onset of ill-health and ill-being.

  6. Exposure to nature versus relaxation during lunch breaks and recovery from work: development and design of an intervention study to improve workers’ health, well-being, work performance and creativity

    Science.gov (United States)

    2014-01-01

    Background The objective of this research project is to understand and to improve workers’ recovery from work stress. Although recovery during lunch breaks is the most common within-workday break, it has received only minor research attention. Therefore, we will study whether lunch breaks including a relaxation session or exposure to nature have more favorable outcomes than usually spent lunch breaks concerning: a) recovery processes, b) health, c) well-being, d) job performance and e) creativity. We approach recovery by combining the theoretical frameworks of work and environmental psychology. Methods/Design We conduct an intervention study in a sample of 268 knowledge-workers who engage in different lunch break activities for 15-minutes per day, two weeks in a row. We randomly assign participants to three experimental conditions: 1) exposure to nature, 2) relaxation and 3) control group (lunch break spent as usual). Online questionnaires before and after the intervention assess long term changes regarding recovery processes and the major outcome variables. Before, during and after the intervention, SMS and paper-pencil questionnaires measure the same constructs four times a day with fewer items. We also measure blood pressure and collect saliva samples to map cortisol excretion across the intervention period. A timed experimental task (i.e., the Alternative Uses Task) is used to examine differences in creativity between the three groups after the intervention period. Discussion By combining the knowledge of work and environmental psychology about recovery and restorative experiences, by merging three recovery perspectives (settings, processes, and outcomes) and by using data triangulation, we produce valid results that broaden our view on mechanisms underlying recovery and enhance our understanding about their links to psychological, behavioural and physiological outcomes, resulting in a more comprehensive picture of work stress recovery in general.

  7. Magnitude of Treatment Abandonment in Childhood Cancer.

    Full Text Available Treatment abandonment (TxA is recognized as a leading cause of treatment failure for children with cancer in low-and-middle-income countries (LMC. However, its global frequency and burden have remained elusive due to lack of global data. This study aimed to obtain an estimate using survey and population data.Childhood cancer clinicians (medical oncologists, surgeons, and radiation therapists, nurses, social workers, and psychologists involved in care of children with cancer were approached through an online survey February-May 2012. Incidence and population data were obtained from public sources. Descriptive, univariable, and multivariable analyses were conducted.602 responses from 101 countries were obtained from physicians (84%, practicing pediatric hematology/oncology (83% in general or children's hospitals (79%. Results suggested, 23,854 (15% of 155,088 children 6% were outside the capital. Lower national income category, higher reliance on out-of-pocket payments, and high prevalence of economic hardship at the center were independent contextual predictors for TxA ≥ 6% (p<0.001. Global survival data available for more developed and less developed regions suggests TxA may account for at least a third of the survival gap between HIC and LMC.Results show TxA is prevalent (compromising cancer survival for 1 in 7 children globally, confirm the suspected high burden of TxA in LMC, and illustrate the negative impact of poverty on its occurrence. The present estimates may appear small compared to the global burden of child death from malnutrition and infection (measured in millions. However, absolute numbers suggest the burden of TxA in LMC is nearly equivalent to annually losing all kids diagnosed with cancer in HIC just to TxA, without even considering deaths from disease progression, relapse or toxicity-the main causes of childhood cancer mortality in HIC. Results document the importance of monitoring and addressing TxA as part of childhood

  8. Long-Term Forest Dynamics and Land-Use Abandonment in the Mediterranean Mountains, Corsica, France

    2013-06-01

    Full Text Available Human practices have had an impact on Mediterranean ecosystems for millennia, particularly through agricultural and pastoral activities. Since the mid-19th century, land-use abandonment has led to the expansion of shrubland and forest, especially in the mountainous areas of the northern Mediterranean basin. Knowledge of these factors is vital to understanding present forest patterns and predicting future forest dynamics in the Mediterranean mountains. We aimed to analyze and understand how land-use abandonment affected spatial modifications of landscapes in two study areas, 44,000 ha and 60,000 ha, located on the island of Corsica, France, representing a typical Mediterranean environment with chestnut forests. Our approach used land-cover archive documents from 1774, 1913, 1975, and 2000, and human population history, 1770 to present day, to describe landscape patterns following land-use abandonment. This research showed that dramatic changes in landscape at the two study areas were caused by the suspension of human influence and the interruption of traditional farming practices. Over the study period, both study sites showed significant reforestation of shrubland and cultivated areas marked by the presence of Quercus ilex forests (+3.40% yr-1 between 1975 and 2000 and by Pinus pinaster (+3.00% yr-1 between 1975 and 2000 at one study site that had experienced heavy rural exodus. At the same time, areas containing chestnut forests decreased by 50% between 1774 and 2000 (-0.09% yr-1 between 1774 and 1975 and -1.42% yr-1 between 1975 and 2000. Shrubland expansion remained limited at both study sites. Our study highlights the value of small-scale approaches for understanding the ecological consequences of land-use abandonment and present and future land-management decisions. Discussion concludes on the importance of working with long-term series for studies on resilience in social-ecological systems and on the consequences in terms of provision of

    2004-12-01

    Full Text Available OBJECTIVE: To carry out a survey data collection from health care workers in Brazil, Croatia, Poland, Ukraine and the USA with two primary goals: (1 to provide information about which aspects of well-being are most likely to need attention when shiftwork management solutions are being developed, and (2 to explore whether nations are likely to differ with respect to the impacts of night work on the well-being of workers involved in health care work. METHODS: The respondents from each nation were sorted into night worker and non-night worker groups. Worker perceptions of being physically tired, mentally tired, and tense at the end of the workday were examined. Subjective reports of perceived felt age were also studied. For each of these four dependent variables, an ANCOVA analysis was carried out. Hours worked per week, stability of weekly work schedule, and chronological age were the covariates for these analyses. RESULTS: The results clearly support the general proposal that nations differ significantly in worker perceptions of well-being. In addition, perceptions of physical and mental tiredness at the end of the workday were higher for night workers. For the perception of being physically tired at the end of a workday, the manner and degree to which the night shift impacts the workers varies by nation. CONCLUSIONS: Additional research is needed to determine if the nation and work schedule differences observed are related to differences in job tasks, work schedule structure, off-the-job variables, and/or other worker demographic variables.OBJETIVO: Coletar dados de pesquisa de profissionais da saúde no Brasil, Croácia, Polônia, Ucrânia e Estados Unidos com duas metas principais: (1 proporcionar informações quanto a aspectos do bem-estar que mais provavelmente precisam de atenção durante a elaboração de soluções administrativas para os turnos de trabalho e (2 examinar a existência de possíveis diferenças entre os países quanto ao

    In the Old Coal Mine District of East Limburg, in the south of the Netherlands, a number of abandoned mine shafts exist of which the exact coordinates are uncertain. The area is now densely populated, and the majority of the shafts are located near or underneath roads and/or houses. Some of these shafts urgently need to be secured for reasons related to a recent rise in deep ground water levels. This paper describes preliminary investigations for abandoned mine shafts by means of aerial photographs and georadar. Inspection of various photo series indicates that the chances of finding clues for abandoned mine shafts are reasonable, and that digital techniques facilitate identification and exact determination of shaft coordinates. In a densely populated survey environment, such as the area in which the abandoned shafts are located, georadar is a suitable shallow geophysical method for mine shaft detection. In these circumstances, shielded antennae give a clearer subsurface image than unshielded antennae. Signal penetration in the loess-rich deposits commonly found in the area is limited, but the results of a trial survey over a known abandoned shaft accurately confirm the geometry of a collapse zone surrounding the shaft center.

    Sweet chestnut has been fundamental for Italian mountainous economies for many centuries. This kind of forest was traditionally managed by coppicing in shortly rotation (15-20 years) to rapidly produce wood biomass until half of XX century. In the last decades these forests were in large part abandoned due to change in economy which made coppiced forest management unprofitable, especially in steeper slopes and where forest viability is scarce. As a consequence most of them are over aged and very dense, leading to an observed increasing in localized slope instability, primary because of the uprooting of stools (Vogt et al., 2006). In this work the effect of the abandon of chestnut coppice on slope stability was analyzed, focusing on shallow landslides triggering. The mechanical contribution to soil shear strength of differently managed chestnut stand was estimated and compared in terms of additional root cohesion. The study area is located in the Valcuvia Valley (Lombardy Prealps - Northern Italy) at an elevation about 600 m a.s.l., where two different stands, one managed and the other abandoned (over 40 year aged), were chosen. The two sampling stands are on cohesionless slopes (quaternary moraine deposits) and are homogeneous with regard to the substrate, exposure and elevation. Slope steepness influences heavily forestry practices and steeper stands are more frequently abandoned than stands on gentler terrain: in fact in the abandoned coppice the slope was higher (35 degrees against 13 in the managed stand) and no stands completely homogeneous can be found. In each site the main characteristics of the stand were surveyed and a trench in each stand was excavated to analyze root diameter and number distribution with depth; root specimens were also collected for the tensile force determination through laboratory tensile tests. Root distribution and force were then used to estimate root cohesion values through a Fiber Boundle Model (Pollen and Simon, 2005). Results

    The abandoning of nuclear energy can not be considered without economic and social damages, it would amplify the des-industrialization process of France and would spoil its energy independence and would mean a step backwards in terms of world strategy. In France the nuclear sector gives work to a total of 410.000 people and generates a total added value of 33 billions euros each year. It would make no sense to stop an activity whose perspective is promising: a lot of reactors in the world will need soon maintenance, upgrading or replacement. (A.C.)

  16. Modeling Wood Encroachment in Abandoned Grasslands in the Eifel National Park - Model Description and Testing.

    Directory of Open Access Journals (Sweden)

    Silvana Hudjetz

    Full Text Available The degradation of natural and semi-natural landscapes has become a matter of global concern. In Germany, semi-natural grasslands belong to the most species-rich habitat types but have suffered heavily from changes in land use. After abandonment, the course of succession at a specific site is often difficult to predict because many processes interact. In order to support decision making when managing semi-natural grasslands in the Eifel National Park, we built the WoodS-Model (Woodland Succession Model. A multimodeling approach was used to integrate vegetation dynamics in both the herbaceous and shrub/tree layer. The cover of grasses and herbs was simulated in a compartment model, whereas bushes and trees were modelled in an individual-based manner. Both models worked and interacted in a spatially explicit, raster-based landscape. We present here the model description, parameterization and testing. We show highly detailed projections of the succession of a semi-natural grassland including the influence of initial vegetation composition, neighborhood interactions and ungulate browsing. We carefully weighted the single processes against each other and their relevance for landscape development under different scenarios, while explicitly considering specific site conditions. Model evaluation revealed that the model is able to emulate successional patterns as observed in the field as well as plausible results for different population densities of red deer. Important neighborhood interactions such as seed dispersal, the protection of seedlings from browsing ungulates by thorny bushes, and the inhibition of wood encroachment by the herbaceous layer, have been successfully reproduced. Therefore, not only a detailed model but also detailed initialization turned out to be important for spatially explicit projections of a given site. The advantage of the WoodS-Model is that it integrates these many mutually interacting processes of succession.

    2016-04-01

    As urban and suburban areas expand into previously unoccupied sites, the problem of accurately determining the locations of abandoned mine workings and the possible effects of fault reactivation on surface subsidence becomes more important. Here, we present the results of DC electrical resistivity imaging (ERI) surveys above an abandoned coal mine in the Jurassic Walloon Coal Measures of the Clarence-Moreton Basin, Queensland. Objectives were to: (1) locate the surface entrance to a coal mine access shaft, (2) determine the extent of the mine workings, (3) determine if the workings are open, partly- or fully-collapsed, (4) locate the possible existence of a high angle fault delineating the western extent of the workings. Coal seams were mined underground by the bord-and-pillar technique at the site until the first half of the 20th century to within ~20 m of the ground surface. This has led to ground settlement post-abandonment, with an additional hazard of this stress-redistribution being the possible reactivation of steeply-dipping faults known to pervade the coal measures. After an initial site reconnaissance, desktop study and modelling, it was determined that existing mine plans, maps and records were poorly kept and inaccurate, making a satisfactory geotechnical risk assessment prior to land development and construction difficult. The 2D ERI transects, coupled with boreholes, identified lateral zones of moderate-high resistivity that are interpreted to be partly-collapsed workings. The second key feature identified was a reverse fault that delineated the western edge of the mine workings. The key outcome is that for abandoned mine risk assessment to be optimised, careful integration of geophysical data and direct testing needs to be made.

    2011-07-01

    The Zuata Field in the Orinoco oil belt, Venezuela, has important recoverable reserves but faces sand production and low reservoir pressures in many cases. Thus solid removal and cleaning are necessary and increase stimulation time and cost. The aim of this paper is to present a new technique for minimizing the rig time/cost. This new scheme of completion uses a cleaning technology with CCTU WellVac SandVac to clean the filling and remove formation damage from low pressure wells. Field tests were conducted in the Zuata Field on two wells operated by PDVSA. The new methodology proved successful in stimulating low pressure reservoirs and results showed that sediments were removed without significant loss of fluids, the CAPEX/OPEX per well was reduced and profitability in low and medium production wells increased. The methodology proposed herein was shown to be a good alternative for stimulating and cleaning low productivity wells.

    Commercial and centralized drilling-fluid disposal (CCDD) sites receive a portion of spent drilling fluids for disposal from oil and gas exploration and production (E&P) operations. Many older and some abandoned sites may have operated under less stringent regulations than are currently enforced. This study provides a census, compilation, and summary of information on active, inactive, and abandoned CCDD sites in Louisiana, New Mexico, Oklahoma, and Texas, intended as a basis for supporting State-funded assessment and remediation of abandoned sites. Closure of abandoned CCDD sites is within the jurisdiction of State regulatory agencies. Sources of data used in this study on abandoned CCDD sites mainly are permit files at State regulatory agencies. Active and inactive sites were included because data on abandoned sites are sparse. Onsite reserve pits at individual wells for disposal of spent drilling fluid are not part of this study. Of 287 CCDD sites in the four States for which we compiled data, 34 had been abandoned whereas 54 were active and 199 were inactive as of January 2002. Most were disposal-pit facilities; five percent were land treatment facilities. A typical disposal-pit facility has fewer than 3 disposal pits or cells, which have a median size of approximately 2 acres each. Data from well-documented sites may be used to predict some conditions at abandoned sites; older abandoned sites might have outlier concentrations for some metal and organic constituents. Groundwater at a significant number of sites had an average chloride concentration that exceeded nonactionable secondary drinking water standard of 250 mg/L, or a total dissolved solids content of >10,000 mg/L, the limiting definition for underground sources of drinking water source, or both. Background data were lacking, however, so we did not determine whether these concentrations in groundwater reflected site operations. Site remediation has not been found necessary to date for most abandoned

  5. Hazardous waste: Abandoned disposal sites may be affecting Guam's water supply

    Energy Technology Data Exchange (ETDEWEB)

    1987-01-01

    In 1978 Anderson Air Force Base in Guam discovered that the base's drinking water was contaminated with the cleaning solvent trichloroethylene, a suspected carcinogen. The sources of the contamination were old, abandoned landfills where the solvents had been disposed. Testing of the drinking water has been sporadic and has not included water consumed by portions of the installation populace. Anderson officials established procedures to test water samples monthly at different points in the water distribution system and if the test results indicate contamination, corrective action will be taken to make the drinking water safe, or the wells will be shut down.

    2013-04-01

    Plants growing on abandoned mine sites are of particular interest in the perspective to remediate contaminated soils by phytoremediation, a low cost and environmental friendly technique which uses metal-accumulator plants to clean up moderately contaminated areas. The choice of plants is a crucial aspect for the practical use of this technique, given the ability to accumulate metals in their tissues, being genetically tolerant to high metal concentrations. Up today, more than 400 native plants that hyperaccumulate metals are reported, Brassicaceae being the family with the largest number of hyperaccumulator species. For example, Alyssum bertoloni is well known as Ni accumulator, as well as Thlaspi caerulescens for Zn and Brassica napus for Pb. However, metal hyperaccumulation is not a common phenomenon in terrestrial higher plants, and many of the European hyperaccumulator plants are of small biomass, and have a slow growth rate. Therefore, there is an urgent need for surveying and screening of plants with ability to accumulate metals in their tissues and a relatively high biomass. In recent years, a survey of soils and plants growing on contaminated areas at several abandoned sulphide mines in Italy was carried out by working groups of the Universities of Florence, Siena, Cagliari, Bologna, Udine and Venice, in order to evaluate the ability of these plants to colonize mine waste and to accumulate metals, in the perspective of an ecological restoration of contaminated sites. We investigated the heavy metal concentration of the waste material, and the soils developed from, in order to determine the extent of heavy metal dispersion, and the uptake by plants, and deserved attention to wild plants growing at that sites, to find out new metal-tolerant species to utilize in soil remediation. Current results of these investigations, with particular emphasis on the Tuscan areas, are reported here. All the studied profiles are strongly enriched in metals; their

    1990-03-01

    Full Text Available Adoption and Abandonment of Dual Exchange Rate Systems When facing persistent balance of payments problems, some countries have resorted to a dual exchange rate system as an alternative to a uniform exchange rate adjustment. Typically, under the dual system, certain selected transactions take place at a fixed official exchange rate, while there remaining transactions are effected at a more depreciated rate, which is usually determined by market forces. This paper examines the circumstances that lead to the adoption of a dual system, and the conditions under which the foreign exchange market can be unified successfully or a later stage. In this paper, the adoption of the dual system is linked to the unsustainability of a crawling peg (or a fixed exchange rate system in the presence of large budgret deficits. We show that the initiai spiral between the financial at the commercial exchange rates and the extent of capital flight largely depends on whether the switch in regime is anticipated or unanticipated. Although the dual system improves the external position of the economy, to the extent that there is no change in domestic noticies the country will continue to experience a deficit in the balance of payments. A correction of these policies is the only enduring solution to the external imbalance, and a precondition for a successful unification of the foreirg exchange market. If the economv unifies the foreign exchange market into a crawling peg, the financial exchahnge rate could be an adequate indicator of the initlal level of which the new exchange rate should be set if a capital outflow is to be avoided. If the economy instead moves to a flexible exchange rate system, the initial value of the exchange rate could be higher or lower than the prevailing financial exchange rate.

    Full Text Available Female genital mutilation (FGM, sometimes referred to as female circumcision or female genital cutting, is a harmful cultural practice without any known health benefit. Its short-term and long-term health risks have led to numerous initiatives toward its eradication at international and local levels, over the last two decades. While major challenges remain and millions of girls and women are still at risk of being subjected to FGM, there is growing evidence that interventions that take into account the social dynamics that perpetuate FGM are yielding positive results toward its reduction. Well-recognized as a human rights violation in international treaties, the elimination of female genital mutilation requires ongoing interventions through cross-sectoral approaches that address attitudinal, cultural and behavioral change.

    Hunting cheetah reportedly store metabolic heat during the chase and abandon chases because they overheat. Using biologging to remotely measure the body temperature (every minute) and locomotor activity (every 5 min) of four free-living cheetah, hunting spontaneously, we found that cheetah abandoned hunts, but not because they overheated. Body temperature averaged 38.4°C when the chase was terminated. Storage of metabolic heat did not compromise hunts. The increase in body temperature following a successful hunt was double that of an unsuccessful hunt (1.3°C ± 0.2°C versus 0.5°C ± 0.1°C), even though the level of activity during the hunts was similar. We propose that the increase in body temperature following a successful hunt is a stress hyperthermia, rather than an exercise-induced hyperthermia.

  17. Listing causes of risk of vulnerability and abandonment

    María Luisa Santamaría Pérez

    2016-11-01

    Full Text Available In a state of law, a citizen must live under the protection of their fundamental rights. Therefore, when authorities makes an intervention in a family nucleus and separates children from their parents for alleged protection purposes, it should be noted that if the decision was misguided, during the time that the separation remains, fundamental rights of the whole family are being infringed, especially for children, as stated in Article 9 of the CRC. With these premises, this article reveals that the reasons of risk and abandonment of a child should be typified in order to ensure the full success of the decisions of family separation. In addition, following a declaration of abandonment of a child, a lawsuit should be arise, whose procedural aspects would ensure fully adequate protection of the fundamental rights of the child in question, regardless of their parents' litigator ability.

  18. A Critique of Block on Abortion and Child Abandonment

    Directory of Open Access Journals (Sweden)

    Jakub Bożydar Wiśniewski

    2010-05-01

    Full Text Available The present paper offers a critique of Block on the issues of abortion and child abandonment. Block regards aborting a fetus or abandoning a child as an instance of exercising one’s libertarian right of expelling trespassers from one’s private property. I argue that the above reasoning is flawed due to the lack of the appreciation of the fact that if one voluntarily initiates the causal chain which leads to someone else ending up on his property, the latter person cannot be considered a trespasser. Furthermore, in the light of the above observation, any direct effects resulting from that person’s eviction should be considered the responsibility of the property’s owner. All of this follows from the simple logical fact that in all links of the causal chain under consideration the owner is the ultimate causal agent.

    2011-01-01

    We have studied three plans for re-use of the abandoned mine roadway tunnels as an energy center.These are the thermostat plan,the thermal accumulator plan,and the CAES plan.Calculations show that the thermostat plan can provide over 15,000 m2 of building air-conditioning/heating load for each kilometer of roadway,but electric power is needed to run the system.Numerical research proved that the accumulation of hot water in the roadway for seasonal heating purposes (a temperature swing from 90 to 54 ℃) is a viable possibility.The CAES plan proposes using the discarded coal mine tunnel as a peaking power station with an energy storage density over 7000 kJ/m3.It can be concluded that presently abandoned coal mines could be reformed into future energy centers for a city.

    Full Text Available With technology constantly improving, modern highways can nowadays be built through terrains where construction used to be either technically infeasible or too costly. While this results in faster connections and shorter commuting times, it leaves the abandoned historic routes behind without any use. This workshop was aimed at developing solutions for the requalification of abandoned highway sections, focusing on the example of the Autostrada del Sole which bypasses the little town of Vado, Bologna. A concept of converting the section into a Sole Park - a park which offers both relaxation and amusement elements - was developed in order to attract visitors from the neighboring villages and the high-speed highway. Within this context, potential locations for lookouts were identified, giving stunning vistas of the Tuscan-Emilian landscape.

    This document is a compendium of results of the 1995 Monitor Well Inspection and Maintenance Program at the US Department of Energy`s Oak Ridge Y-12 Plant. This report documents the work relating to well inspections and maintenance requests. Inspections are implemented in order to better assess the condition and maintenance needs of wells that are actively being monitored. Currently this approach calls for inspecting all wells on a routine (annual or triennial) basis which are: (1) in an active sampling program; (2) included in a hydrologic study; or (3) not in service, but not scheduled for plugging and abandonment. Routine inspections help to ensure that representative groundwater samples and hydrologic data are being collected, and contribute to the effective longevity of each well. This report formally presents well inspection and maintenance activities that were conducted at the Y-12 Plant from August through December 1995.

  2. Characterization of abandoned rocket body families for active removal

    2016-09-01

    A new ranking index was developed and applied to a wide set of rocket body families, characterized by stage dry masses greater than 500 kg and by the presence of at least 5 stages abandoned in LEO. The upper stages selected accounted for more than 80% of the unclassified rocket bodies in LEO and nearly 95% of the associated dry mass. The detailed results obtained for 657 objects clearly identified the most critical altitude-inclination bands and stage models, to be targeted first if and when a debris remediation strategy including the active removal of intact abandoned objects were deemed necessary. Apart from the evaluation of the criticality regarding the long-term evolution of the debris environment, resulting in a priority listing for optimal active removal, the application of the new ranking index is not limited to debris remediation. In fact, if applied before launch to spacecraft and rocket bodies to be disposed in orbit, at the end of mission, it would provide an additional debris mitigation analysis tool for evaluating competing disposal options. Concerning the rocket bodies abandoned in LEO, 274 resulted to have a criticality equal or larger than the average intact object abandoned in an 800 km sun-synchronous orbit. Among them, 243 belonged to the Russian Federation and Ukraine, 25 to China, 5 to Europe and 1 to Japan. In addition to being concentrated in relatively few and narrow altitude-inclinations bands, the most numerous rocket body families often present a quite uniform distribution in right ascension of the ascending node, which is especially convenient for multiple target removal missions.

A case presentation is followed by a description of diagnostic and management challenges, a review of the relevant literature, and a summary of the authors' suggested management approaches. The goal of this series is to help readers better understand how to apply the results of key studies, including those published in Journal of Clinical Oncology, to patients seen in their own clinical practice.A 46-year-old premenopausal woman with a body mass index of 21 was found on screening mammography to have a new, approximately 1-cm spiculated mass with associated calcifications in the upper outer quadrant of the left breast. Stereotactic core biopsy showed a focus of invasive duct carcinoma, strongly positive for estrogen and progesterone receptors and negative for human epidermal growth factor receptor 2, with associated ductal carcinoma in situ. Clinical examination revealed no palpable mass or axillary lymphadenopathy. She underwent a left lumpectomy with seed localization and sentinel lymph node biopsy. Final pathology revealed an 8-mm well-differentiated invasive carcinoma without lymphovascular invasion and intermediate grade ductal carcinoma in situ. The margins were clear, and three sentinel lymph nodes were negative for metastasis. The 21-gene recurrence score was 10, suggesting a 7% risk of 10-year distant recurrence with adjuvant endocrine treatment. After the completion of adjuvant radiotherapy (42.50 Gy in 16 fractions to the breast), the patient has returned for a follow-up visit. She is a professional violinist and would like to know what she can do to prevent lymphedema on her upcoming flight to Vienna.

    Full Text Available Housing industry is one of the most dynamic, risky, and challenging industries. In Malaysia, this industry has a poor reputation for managing risks, with many major projects failing to be completed within the allotted time. Due to the inherent risks involved in construction projects, it is essential to recognize the risks that cause problems associated with abandoned housing projects. Therefore, this study aims to identify the risks that contribute to issues of abandoned housing projects and to propose mitigation strategies. The methodologies used in this study are combination of qualitative and quantitative methods of literature review, questionnaire survey, and interview. The results show that many risks are involved in housing project, including risks related to environmental impacts, construction, politics, law, management, finance, materials, and economy, of which the probability of risks from unexpected ground condition, project delays, bureaucracy, contractual disputes between developer and landlord, weakness in management by inexperience developer, and financial crisis is very high. It was also found that all relevant parties involved in housing industry are required to have extensive cooperation in advance and should perform systematic risk management strategies in order to mitigate the risks leading to problems associated with abandoned housing projects.

  5. Secondary Forests from Agricultural Abandonment in Amazonia 2000-2009

    Ongoing negotiations to include reducing emissions from tropical deforestation and forest degradation (REDD+) in a post-Kyoto climate agreement highlight the critical role of satellite data for accurate and transparent accounting of forest cover changes. In addition to deforestation and degradation, knowledge of secondary forest dynamics is essential for full carbon accounting under REDD+. Land abandonment to secondary forests also frames one of the key tradeoffs for agricultural production in tropical forest countries-whether to incentivize secondary forest growth (for carbon sequestration and biodiversity conservation) or low-carbon expansion of agriculture or biofuels production in areas of secondary forests. We examined patterns of land abandonment to secondary forest across the arc of deforestation in Brazil and Bolivia using time series of annual Landsat and MODIS data from 2000-2009. Rates of land abandonment to secondary forest during 2002-2006 were less than 5% of deforestation rates in these years. Small areas of new secondary forest were scattered across the entire arc of deforestation, rather than concentrated in any specific region of the basin. Taken together, our analysis of the satellite data record emphasizes the difficulties of addressing the pool of new secondary forests in the context of REDD+ in Amazonia. Due to the small total area of secondary forests, land sparing through agricultural intensification will be an important element of efforts to reduce deforestation rates under REDD+ while improving agricultural productivity in Amazonia.

  8. A Coupled Economic and Physical Model of Coastal Adaptation and Abandonment: Are human occupied coastlines a bubble waiting to burst?

    McNamara, D.; Keeler, A.

    2011-12-01

    Policy discussions of adaptation by coastal residents to increasing rates of sea level rise and changing frequency of damaging storms have focused on community land use planning processes. This view neglects the role that market dynamics and climate change expectations play in the way coastal communities choose among risk mitigation options and manage land use decisions in an environment of escalating risks. We use a model coupling physical coastal processes with an agent-based model of behavior in real estate and mitigation markets to examine the interplay of climate-driven coastal hazards, collective mitigation decisions, and individual beliefs. The physical component model simulates barrier island processes that respond to both storms and slow scale dynamics associated with sea level rise. The economic component model is an agent-based model of economic behavior where agents are rational economic actors working off different assessments of future climate-driven events. Agents differentially update their beliefs based on a) how much emphasis they give to observed coastal changes and b) how much weight they give to scientific predictions. In essence, agents differ along a spectrum of how much they believe that the past is the best guide to the future and how quickly they react to new information. We use the coupled model to explore three questions of interest to coastal policy. First, how do the interplay of costal processes, beliefs, and mitigation choices affect the level and stability of real estate prices? Second, how does this interplay affect the incentives for community investments in shoreline protection? Third, how do expectations and reactions to observed events, as well as mitigation investments, affect the built environment in circumstances when climate risks reach very high levels? This last question relates to a key aspect of climate change adaptation on the coast - when does mitigation give way to abandonment as an optimal adaptation strategy

  9. Radon concentrations in abandoned mines, Cumbria, UK: safety implications for industrial archaeologists

    2011-05-01

    Full Text Available This paper presents a number of surveys performed in a geographical area of the UK, part of which until recently was considered low radon risk. The Cumbrian region was identified by the Building Research Establishment (BRE in its 1999 guide as an area without a significant radon problem in the built environment. The geology of the region, which includes the Northern Pennine Orefield is varied, but consists of granites, andesites, tuffs, carbonates, sandstones and shales. Mineralisation has taken place (mostly lead and copper ores primarily along fault and fracture zones, one example being Copper Valley, northwest of Coniston village. This work quantifies the risk of exposure to radon in a number of abandoned mine environments. High radon levels, up to 28 589 Bq m−3, have been measured in parts of one mine. This study demonstrates that industrial archaeologists (such as the Cumbrian Amenity Trust Mining History Society or CATMHS members and explorers of abandoned mines can be at risk from radon exposure and it proposes a management scheme to allow industrial archaeologists to continue exploration whilst minimising the risk to health from radon.

  11. Leak Path Development in CO2 Wells

    2014-12-01

    Wells have in numerous scientific works been denoted the "weak link" of safe and cost-efficient CO2 Capture and Storage (CCS). Whether they are active or abandoned, all wells are man-made intrusions into the storage reservoir with sealing abilities depending on degradable materials like steel and cement. If dense CO2 is allowed to expand (e.g. due to leakage) it will cool down its surroundings and cause strong thermal and mechanical loading on the wellbore. In addition, CO2 reacts chemically with rock, cement and steel. To ensure long-term underground containment, it is therefore necessary to study how, why, where and when leakage occurs along CO2wells. If cement bonding to rock or casing is poor, leak paths can form already during drilling and completion of the well. In the present work, we have mapped the bonding quality of cement-rock and cement-steel interfaces - and measured their resistance towards CO2 flow. This involved a large experimental matrix including different rocks, steels, cement types and well fluids. The bonding qualities were measured on composite cores using micro computed tomography (µ-CT), and CO2 was flooded through the samples to determine leakage rates. These were further compared to numerical simulations of leakage through the digitalized µ-CT core data, and CO2chemical interactions with the materials were mapped using electron microscopy. We also present a new laboratory set-up for measuring how well integrity is affected by downhole temperature variations - and we showcase some initial results. Our work concludes that leak path development in CO2 wells depends critically on the drilling fluids and presflushes/spacers chosen already during drilling and completion of a well. Fluid films residing on rock and casing surfaces strongly degrade the quality of cement bonding. The operation of the well is also important, as even slight thermal cycling (between 10°C and 95°C on casing) leads to significant de-bonding of the annular cement.

    In order to understand the mechanism and regularity of the groundwater contamination from mine water of abandoned mines, experiments were conducted on an abandoned coal mine in Fuxin, a representative city with lots of mine water in northeast China. The groundwater pollution from different contaminants of coal-mining voids (total hardness, SO2-4, Cl and total Fe) and pollution factors transportation situation in the coal rock were simulated by soil column experiment under the conditions of mine water leaching and main water leaching (similar to rainwater leaching), and the water-rock interaction mechanism was discussed during mine water infiltration through saturated coal rock by application of principle of mass conservation, based on physical properties of coal rock, as well as monitored chemical composition. The results show that, compared with the clear water leaching process, trends of change in pollutant concentrations presented different characteristics in the mine water leaching process. Groundwater is contaminated by the water rock interactions such as migration & accumulation, adsorption & transformation,dissolution & desorption and ion exchange during the mine water permeation. The experiments also suggest that at first dissolution rate of some kinds of dissoluble salts is high,but it decreases with leaching time, even to zero during both the mine water leaching and main water leaching.

    The current economic crisis has left numerous residential developments in the southeastern United States in various stages of construction.Many of them are currently graded and essentially abandoned,creating a major source of sediment runoff to waterways.Residential development locations with significant bare soil areas were identified through classification of Landsat 5 TM satellite imagery and subsequently verified from high-resolution county aerial photographs.The revised universal soil loss equation (RUSLE) was used in a geographic information system (GIS) as a tool for prioritizing identified locations on the basis of potential soil loss assuming the worst case scenario of a completely unmaintained site.Initial GIS identification indicated 301 sites with a total bare soil area of 2 378 ha over three counties in Upstate South Carolina.A random sample of 153 sites was visited over 17 days and assessed using a mobile GIS,global positioning system (GPS),and digital camera for field validation.Results indicated that 78% (119) of the sites were classified correctly (residential construction sites in varying stages of completion); 88% of identified areas were less than 25% built compared to the previous year; 48% were categorized as moderate to severe problems.Abandoned and unfinished developments in Upstate South Carolina may represent a major source of sediment pollution to streams.Well-maintained erosion control devices may be useful in preventing offsite sedimentation.

    Full Text Available Within days of each other, Pfizer, Merck, and GlaxoSmithKline announced that they will focus on a few therapeutic areas only and abandon others entirely. Pfizer alone will close well over a hundred drug development projects that have reached two-thirds of the way to launch. The programs are deemed to be too risky and not lucrative enough for Big Pharma in the current climate. Society has a real need for the drugs that are no longer going to be developed for, among others, drug-resistant epilepsy, neuropathic and cancer pain, type-2 diabetes, obesity, and schizophrenia. The authors propose a radical response by the U.S. government and the National Institutes of Health to rescue these abandoned projects, and to continue selected programs for drug approval by the U.S. Food and Drug Administration and the European Medicines Agency. The investment required is small compared to the Troubled Asset Relief Program bank bail out, but the return on investment in financial terms and in satisfying societal needs makes this proposal attractive.

    Full Text Available In the developing phase of a hydrocarbon reservoir and planning for drilling the production wells, it is necessary to drill the wells in an appropriate spacing to achieve maximum economic revenues during the reservoir life span. Well spacing which is the real location and interrelationship between producing oil or gas wells in an oil field is an important parameter. It is determined for the maximum ultimate production of a given reservoir and should be taken in consideration during well planning to avoid drilling of unnecessary wells. This study presents the concept of drainage area on horizontal well and horizontal productivity indices with different equations and their applications. A user friendly Excel Spreadsheet program was developed to calculate the productivity values of horizontal wells using three major available productivity equations. Also, the developed spreadsheet program was used to evaluate the effect of well spacing on the productivities of horizontal wells using productivity index approach and drainage area concept. It also helps to review the comparison between vertical and horizontal wells spacing based on drainage area concept. This program was validated, and then was used to study the effect of horizontal well length on the ratio of horizontal well productivity to vertical well productivity. The results show that higher ratio of horizontal well productivity to vertical well productivity values are obtained with increase length of the horizontal well. It is a very useful tool for making decision about the application of well spacing for horizontal wells.

    Since the days of the Spanish and Portuguese conquerors, South America has been closely associated with the metalliferous ore mining. Gold, silver, tin, lead, tungsten, nickel, copper, and palladium ores have been explored over the last centuries. In addition, there has also been the development and promotion of other economic activities related to mining, as the underground mine tourism. A few works have been published on radon levels in the South American mining. In this study, we investigated the radon transport process and its health hazard in two exhausted and abandoned mines in San Luis Province, Argentina. These mines were chosen because they have different physical configurations in their cavities, features which can affect the air flow patterns and radon concentrations. La Carolina gold mine (32 deg 48' 0'' S, 66 deg 60' 0'' W) is currently a blind end system, corresponding to a horizontal excavation into the side of a mountain, with only a main adit. Los Condores wolfram mine (32 deg 33' 25'' S, 65 deg 15' 20'' W) is also a horizontal excavation into the side of a mountain, but has a vertical output (a shaft) at the end of the main gallery. Three different experimental methodologies were used. Radon concentration measurements were performed by CR-39 nuclear track detectors. The distribution of natural radionuclide activities ({sup 40}K, {sup 232}Th and {sup 238}U) was determined from rock samples collected along their main adits, using in laboratory gamma-ray spectrometry. The external gamma dose rate was evaluated using thermoluminescent dosimeters and a portable survey meter. The values for the {sup 222}Rn concentration ranged from 0.43 {+-} 0.04 to 1.48 {+-} 0.12 kBq/m{sup 3} in the Los Condores wolfram mine and from 1.8 {+-} 0.1 to 6.0{+-}0.5 kBq/m{sup 3} in the La Carolina gold mine, indicating that, in this mine, the radon levels exceed up to four times the action level of 1.5 kBq/m{sup 3

    The knowledge of engineering systems has been developed to choose optimal technology for subsidence prevention over abandoned mines. The expert system treats a specific case, maps consequences of actions and derives relevant technology (or a set of technologies) that should be used to prevent ground subsidence. Input parameters that characterise the case are treated using fuzzy logic and are then fed to a neural network. The network has been successfully trained by a backpropagation algorithm on the basis of three fuzzy rules. 5 refs., 2 figs., 3 tabs.

    Kennedy, Clovis A.

    1980-04-03

    This prospective well of opportunity was originally drilled and completed as a gas producer by Wrightsman Investment Company in early 1973. The original and present producing interval was from 15,216 to 15,238 feet. IMC Exploration Company, Inc. acquired the property from Wrightsman and is the present owner operator. The well is presently shut in s a non-economic producer and IMC proposed to perform plug and abandonment operations in April, 1980. This well has a good geopressured-geothermal water sand behind the 5-1/2 inch casing that has 94 feet of net sand thickness. Pursuant to DOE/NVO authorization of March 11,1980, Eaton negotiated an option agreement with IMC whereby IMC would delay their abandonment operations for a period of 90 days to permit DOE to evaluate the well for geopressure-geothermal testing. The IMC-Eaton option agreements provide that IMG will delay plugging the well until June 15, 1980. If Eaton exercises its option to acquire the well, IMC will sell the well bore, and an adjacent salt water disposal well, to Eaton for the sole consideration of Eaton assuming the obligation to plug and abandon the wells in accordance with lease and regulatory requirements. If Eaton does not exercise its option, then Eaton will pay IMC $95,000 cash and IMC will proceed with plugging and abandonment at the termination of the option period.

    Presently, the BLM (Bureau of Land Management) has identified a multitude of abandoned mine sites in primarily Western states for cleanup. These sites are prioritized and appropriate cleanup has been called in to reclaim the sites. The task is great in needing considerable amounts of agency resources. For instance, in Colorado alone there exists an estimated 23,000 abandoned mines. The problem is not limited to Colorado or to the United States. Cooperation for reclamation is sought at local, state, and federal agency level to aid in identification, inventory, and cleanup efforts. Dangers posed by abandoned mines are recognized widely and will tend to increase with time because some of these areas are increasingly used for recreation and, in some cases, have been or are in the process of development. In some cases, mines are often vandalized once they are closed. The perpetrators leave them open, so others can then access the mines without realizing the danger posed. Abandoned mine workings often fill with water or oxygen-deficient air and dangerous gases following mining. If the workings are accidentally entered into, water or bad air can prove fatal to those underground. Moreover, mine residue drainage negatively impacts the local watershed ecology. Some of the major hazards that might be monitored by higher-resolution satellites include acid mine drainage, clogged streams, impoundments, slides, piles, embankments, hazardous equipment or facilities, surface burning, smoke from underground fires, and mine openings.

    Toxocariasis is an infection that has worldwide distribution. Toxocara canis is the most relevant agent due to its frequent occurrence in humans. Soil contamination with embryonated eggs is the primary source of T. canis. This study aimed to determine the seroprevalence of toxocariasis in 10-month to 3 year-old abandoned infants, considered to be at high risk because of their orphanhood status and early age. Blood samples were collected from 120 children institutionalized in an orphanage in the city of La Plata. In this study, we observed 38.33% of seropositive cases for T. canis by ELISA and 45% by Western blot techniques; significant differences among groups A (2 years) were also found. In research group A, children presented a seropositivity rate of 23.91%, in group B of 42.85% and in group C of 56%, which indicates an increase in frequency as age advances, probably because of greater chances of contact with infective forms of the parasite since canines and soil are frequently infected with T. canis eggs. Abandoned children come from poor households, under highly unsanitary conditions resulting from inadequate or lack of water supply and sewer networks, and frequent promiscuity with canines, which promotes the occurrence of parasitic diseases. These children are highly vulnerable due to their orphanhood status and age.

    Records describing wells located on or near the Hanford Site have been maintained by Pacific Northwest Laboratory and the operating contractor, Westinghouse Hanford Company. In support of the Ground-Water Surveillance Project, portions of the data contained in these records have been compiled into the following report, which is intended to be used by those needing a condensed, tabular summary of well location and basic construction information. The wells listed in this report were constructed over a period of time spanning almost 70 years. Data included in this report were retrieved from the Hanford Envirorunental Information System (HEIS) database and supplemented with information not yet entered into HEIS. While considerable effort has been made to obtain the most accurate and complete tabulations possible of the Hanford Site wells, omissions and errors may exist. This document does not include data on lithologic logs, ground-water analyses, or specific well completion details.

    1982-01-01

    The planning process for a statewide reclamation plan of Ohio abandoned minelands in response to the Federal Surface Mining Control and Reclamation Act of 1977 included: (1) the development of a screening and ranking methodology; (2) the establishment of a statewide review of major watersheds affected by mining; (3) the development of an immediate action process; and (4) a prototypical study of a priority watershed demonstrating the data collection, analysis, display and evaluation to be used for the remaining state watersheds. Historical methods for satisfying map information analysis and evaluation, as well as current methodologies being used were discussed. Various computer mapping and analysis programs were examined for their usability in evaluating the priority reclamation sites. Hand methods were chosen over automated procedures; intuitive evaluation was the primary reason.

  11. L’abandon et l’appel, ou l’optimisme paradoxal de Graham Greene dans The Power and the Glory Abandoned and Called, or Graham Greene’s Paradoxical Optimism in The Power and the Glory

    Full Text Available The Power and the Glory is often seen as a pessimistic, if not tragic, work. However, this fails to consider Greene’s little-known statement to the contrary, as well as important aspects of the novel, one of them being the idea of “glory” in the title. In the narrative itself, a fragmented presence of beauty can be discovered as early as the opening scene, and more particularly within Mr Tench’s seedy universe. Two contrasting worlds are thus intermingled from the very beginning, and the rest of the novel is interspersed with similar examples. A related observation can be made about the feeling of abandonment voiced by most of the characters. When examined more closely, the feeling turns out to be highly ambiguous, and not always devoid of bad faith. It should be contrasted with the repeated phenomenon of calls to responsible action. The most striking one is also found in the opening scene, where the fugitive priest is reminded of his duty by the mysterious, though seedy-looking, native child. And through the priest a call is addressed to Mr Tench, who fails to perceive anything. This call to his repressed conscience is repeated in the final scene when he witnesses the priest’s execution. Newman’s understanding of man’s condition probably underlies such contrasts “between the beautiful and the treacherous”. The degraded world in which most characters evolve is not to be isolated from the experience of conscience which both confirms the reality of this negative state of affairs and, in varying degrees, distances the characters from it.

    This document is a compendium of results of the calendar year 1994 Monitor Well Inspection and Maintenance Program at the Department of Energy Y-12 Plant in Oak Ridge, Tennessee. This report documents the work relating to well inspections and maintenance requests. Inspections are implemented in order to better assess the condition and maintenance needs of wells that are actively being monitored. Currently this approach calls for inspecting all wells on a routine (annual or triennial) basis which are: (1) in an active sampling program; (2) included in a hydrologic study; or (3) not in service, but not scheduled for plugging and abandonment. Routine inspections help to ensure that representative groundwater samples and hydrologic data are being collected, and contribute to the life expectancy of each well. This report formally presents well inspection and maintenance activities that were conducted at the Y-12 Plant during 1994. All inspections were conducted between April and December.

  14. Why do leaf-tying caterpillars abandon their leaf ties?

    Full Text Available Leaf-tying caterpillars act as ecosystem engineers by building shelters between overlapping leaves, which are inhabited by other arthropods. Leaf-tiers have been observed to leave their ties and create new shelters (and thus additional microhabitats, but the ecological factors affecting shelter fidelity are poorly known. For this study, we explored the effects of resource limitation and occupant density on shelter fidelity and assessed the consequences of shelter abandonment. We first quantified the area of leaf material required for a caterpillar to fully develop for two of the most common leaf-tiers that feed on white oak, Quercus alba. On average, Psilocorsis spp. caterpillars consumed 21.65 ± 0.67 cm2 leaf material to complete development. We also measured the area of natural leaf ties found in a Maryland forest, to determine the distribution of resources available to caterpillars in situ. Of 158 natural leaf ties examined, 47% were too small to sustain an average Psilocorsis spp. caterpillar for the entirety of its development. We also manipulated caterpillar densities within experimental ties on potted trees to determine the effects of cohabitants on the likelihood of a caterpillar to leave its tie. We placed 1, 2, or 4 caterpillars in ties of a standard size and monitored the caterpillars twice daily to track their movement. In ties with more than one occupant, caterpillars showed a significantly greater propensity to leave their tie, and left sooner and at a faster rate than those in ties as single occupants. To understand the consequences of leaf tie abandonment, we observed caterpillars searching a tree for a site to build a shelter in the field. This is a risky behavior, as 17% of the caterpillars observed died while searching for a shelter site. Caterpillars that successfully built a shelter traveled 110 ± 20 cm and took 28 ± 7 min to find a suitable site to build a shelter. In conclusion, leaf-tying caterpillars must frequently

  15. PRELIMINARY STUDY OF FISH CULTURE IN ABANDONED SAND MINING POOL

    Full Text Available One of main problems in freshwater aquaculture development in Indonesia, especially in Java, is unavailability of developing zone. It is important to find an underutilized area that meets for industrial scale freshwater aquaculture, i.e. sufficient water supply, wide area, and located in one area or zone. The abandoned mining (sand, tin, etc. pools distributed along the country might be the potential area for freshwater aquaculture business. For example, there are at least 13 water pools with total surface area of 250 ha at 15 km side of Citarum River in Karawang District (West Java Province. This study was conducted to obtain preliminary data about the prospect and potency of fish culture (tilapia, clariid catfish, and ‘patin’ catfish in abandoned sand-mining pools in Karawang District. Mini floating net cages of 1 x 1 x 1.5 m3 size were used for culturing fish, i.e. patin catfish (Pangasianodon hypophthalmus, nile tilapia (Oreochromis niloticus, and clariid catfish (Clarias gariepinus, separately. Patin catfish were stocked at a size of 2 g with a density of 300 fish per cage, tilapia were stocked at a size of 6 g with a density of 400 fish per cage, while  the clariid catfish were stocked at a size of 1.4 g with a density of 980 fish per cage. A floating commercial feed (30%—32% protein, 3%—5% fat was used at a daily rate of 9% biomass weight at the beginning and reduced gradually to 3% at the final culture period. Observed data showed that patin catfish grew from the initial size of 2.08 g to the final size 299.59 g in 5 months, nile tilapia grew from individual initial size of 5.92 g to the final size of 247.12 g in 14 weeks, and clariid catfish grew from initial size of 1.39 g to the final size of 73.10 g in 8 weeks. These three species were technically prospective for aquaculture development in the abandoned sand-mining pools.

  16. ENVIRONMENTAL ASSESSMENT OF OKLAHOMA ABANDONED DRILLING AND PRODUCTION SITES AND ASSOCIATED PUBLIC EDUCATION/OUTREACH ACTIVITIES

    The U.S. Department of Energy has participated with the Oklahoma Energy Resource Board (OERB) since 1995 by providing grant funding for on-going work in both environmental assessment of abandoned oilfield exploration and production sites and associated public education/outreach activities. The OERB, a state agency created in 1993 by the Oklahoma legislature, administers programs funded by an assessment of one tenth of one percent on all oil and natural gas produced and sold in the state of Oklahoma. Approximately one half of the funds are used to assess and remediate abandoned oilfield sites and the other half are being used to educate about the importance of the oil and natural gas industry and OERB's environmental efforts. Financial participation through grant funding by the U.S. D.O.E. has been $200,000 annually which represents approximately 3 percent of OERB's private funding. Most of OERB's revenues come from an assessment of 1/10th of 1% on the sale of crude and natural gas in Oklahoma. The assessment is considered voluntary in that any interest owner may ask for a refund annually of their contributions to the fund. On average, 95% of the assessment dollars have remained with OERB, which shows tremendous support by the industry. This Final Report summarizes the progress of the three year grant. The purpose of this three-year project was to continue the progress of the OERB to accomplish its environmental and educational objectives and transfer information learned to other organizations and producing states in the industry.

  17. Coastal rainforest boundary dynamics during the late Holocene in monsoonal Australia: evidence from radiocarbon dates of abandoned nests of Orange-footed Scrubfowl

    The late Holocene history of monsoon rainforest retreat was explored by radiocarbon dating abandoned Orange-footed Scrubfowl (Megapodius reinwardt Gaimard) nests in coastal savannas in the Northern Territory of Australia. Previous work has demonstrated that in savanna environments this rainforest bird can not build nor maintain the large heaps of soil and leaf litter that it uses for nests. Excavations of two earthen mounds in a savanna habitat verified that they were abandoned Scrubfowl nests, and not Aboriginal middens, given their lack of stratigraphy, non-sequential dating of charcoal in a vertical profile, and absence of archaeological material. Radiocarbon dates of material taken from the surface of abandoned nests were determined for three sites on the coast of the Northern Territory. These analyses revealed that for all three sites, rainforests have contracted within the last 1800 years BP. On Elcho Island an abandoned nest was found to contain the land snail Xanthomelon spheroidea Le Guillou (known to prefer rainforest habitat) with a modern radiocarbon age, suggesting recent contraction of rainforest. The results of this study further weaken the theory that Aboriginal burning was a major cause of rain forest fragmentation in the monsoon tropics, and possibly elsewhere in Australia.

Though conflict and warfare may provide strange points of departure for talking about well-being, imaginaries of happiness...... stand out from a background of hardship and are talked about in both a quite concrete way, as a lack of insecurity, as well as in an abstract way, as realization of social being. However, for most of the people I talk to, happiness remains elusive and evades their desperate attempts to grasp it....... It appears, as such, simultaneously to be what life is most profoundly about, as well as the dimension of it that constantly seems to avoid capture....

  19. 'Moral distress'--time to abandon a flawed nursing construct?

    Science.gov (United States)

    Johnstone, Megan-Jane; Hutchinson, Alison

    2015-02-01

    Moral distress has been characterised in the nursing literature as a major problem affecting nurses in all healthcare systems. It has been portrayed as threatening the integrity of nurses and ultimately the quality of patient care. However, nursing discourse on moral distress is not without controversy. The notion itself is conceptually flawed and suffers from both theoretical and practical difficulties. Nursing research investigating moral distress is also problematic on account of being methodologically weak and disparate. Moreover, the ultimate purpose and significance of the research is unclear. In light of these considerations, it is contended that the notion of moral distress ought to be abandoned and that concerted attention be given to advancing inquiries that are more conducive to improving the quality and safety of moral decision-making, moral conduct and moral outcomes in nursing and healthcare domains.

  20. Contamination from abandoned mine tailings: the geochemical approach

    The oxidation of sulphide minerals in flotation tailings and waste materials in the main source of chemical contamination at abandoned mine sites. Pyrite and the other iron-bearing sulphide minerals are responsible for acid mine drainage which leads to the weathering of other sulphides and mobilizes toxic metals such as Cd, Pb and As. An environment rich in earth-alkaline carbonates buffers the ph close to neutrality and mitigates chemical pollution, but liming is insufficient to control pollution. Prevention has to be based essentially on fighting sulphide oxidation with water covers or organic matter covers impermeable to atmospheric oxygen. Remediation strategies are to be addressed to the application of soft biological technologies.

    Rapid increase in the production of marine shrimps in the coastal zone has resulted in large - scale conversion of mangrove forests to shrimp ponds. Productions of the shrimps in some regions have been unstable. Consequently, a number of ponds are left idle. Restoring environmental conditions within the pond site by planting a suitable mangrove species considered an option. The experiment herein was carried out to explore the effect of planting methods on growth of Nipa palm in abandoned shrimp ponds in the Southern Thailand. Economically, coastal villagers in this area earn their income from the palm in several ways, the most importantly in Nipa sugar production. Most seedlings were planted on top of furrows were constructed in the pond to avoid flooding, except for some seedlings which were planted in the pond base where additional pond sludge were slightly filled up to compare their growth rates. The results showed that planting seedlings with attached rhizomes had the best growth rate and without seedling death at 14 months after planting. At this stage, however, the height of seedlings grown from the fallen fruits was similar to those growth from bare rooted seedlings (70 cm tall). Also, seedling mortality was not observed when growth from fallen fruits whereas about6% mortality was experienced by the bare rooted ones. Among the bare rooted seedling treatments, however no significant differences in growth rates were found when applying the soil with chemical fertilizers or farm manure or liming with CaCO3. In addition, it was found that seedling growth measured at 40 months after planting for those growths in pond base was almost 100% greater than those grown on the furrows. Therefore, this finding may be applied for the restoration of abandoned shrimp ponds by growing Nipa palm.

    Utilization of the openings of the abandoned mines could be planned by the principal parameters such as location and geotechnical impact. The local governments have not only to lead the each stage of the utilization project from the very beginning of conceptual design up to the construction stage, but also to promote the project for the development of public purpose. The possible tentative candidates for the utilization of the abandoned mine openings which are supported by the local governments could be summarized as follows. a. The Gahak mine of Kwangmyung, Kyunggi: The mine caverns which have been served as the storage of the pickled fishes, could be reexcavated by taking into consideration the geotechnical parameters for the public use such as: 1) Training center for the youth, 2) Fermentation and storehouse of marine products, 3) Sightseeing resort, 4) Sports and leisure complex, 5) Underground parking lot, 6) Underground shopping mall and chilled room storage, 7) Library, concert hall and museum. b. Hamtae mine of Taebaek, Kangwon: The Hambaek main haulage way and its shaft should be investigated in detail in order to find out a possible use as the underground challenging park of the coal mining operation. c. Mines of Boryung and Hongsung, Chungnam: Lots of mine caverns have been used as the storehouse for the pickled shrimp. However, they have to be promoted to a large scale industries. d. Imgok mine of Kwangju and Palbong mine of Jeongeup, Chunbuk: Mine caverns which have been used as the storehouse of pickles, need a detailed investigation for alternative promotion. e. Yongho mine of Pusan Dalsung mine of Taegu: Both of the mines are located near metropolitan communities. Reconstruction of the old mine caverns of the Yongho mine is highly recommended for a public use. The caverns of the Dalsung mine could be utilized as the storage facilities. Detailed geotechnical survey and sit investigation could be suggested to design the recommended facilities for both

    This work exploited the application of Haar wavelet approach to sedimentary microfacies analysis using log data and gradually abandoned channel facies identifying. This method first, uses wavelet transformation to separate noise and minutiae from large scale patterns for log data. Then normal channels and gradually abandoned channels are regarding as the same, distinguished from the other sedimentary microfacies by Bayesian model created by SP, RMN and RMG values obtained from the large scale patterns. Finally, according to difference in the RMN-GMG between the two microfacies, the slope of the best fit line of RMN-RMG against depth is used to identify gradually abandoned channels and normal ones. A program to implement the method was developed in C/C++ on C++ Builder platform, which computerizes the sedimentary microfacies analysis with log data and facies ichnography creation. This highly computerized, easy-operating method has been used to analyze the log data of 1 480 wells in the east part of No. 2 south area and 20 wells in No. 1 south area in Daqing Oil Field, and the result was well consistent with that of manual work. The success rate of the procedure in correctly identifying the sedimentary microfacies is 80%, which shows its great potential for use in the exploration of meandering depositional oil fields.%针对测井曲线进行沉积微相分析和渐弃型废弃河道微相计算机自动识别的问题,提出基于Haar小波变换的测井曲线沉积微相和渐弃型废弃河道识别的方法.在该方法中,应用小波分解将测井曲线的信号分解为宏观特征信息、细节信息和噪音信息三部分;将渐弃型废弃河道和普通河道作为同一类,利用Bayes判别分析对经小波变换后得到的SP、RMN、RMG曲线的宏观特征信息建立其判相模型,通过该模型将渐弃型废弃河道和普通河道与其他沉积微相进行分离;利用渐弃型废弃河道和普通河道沉积微相在微电

    2010-01-01

    Turkey Vultures (Cathartes aura) lay their eggs on an existing substrate in the dark recesses of a variety of natural sites (Kirk and Mossman 1998). Although an important requirement of Turkey Vulture nest-site selection is isolation from human disturbances (Kirk and Mossman 1998), their nests have been reported in abandoned buildings since at least the early 1800s (Nuttall 1832). Depopulation of rural areas in North America in recent decades has resulted in many abandoned buildings within the Turkey Vulture's breeding range (Peck 2003). Increased use of abandoned buildings by nesting Turkey Vultures has been implicated in the species' recent northward range expansion (Peck 2003, Nelson et al. 2005, Houston et al. 2007). Although abandoned or inoperative vehicles also are widespread in rural areas, we found no published literature documenting Turkey Vultures' use of these potential nest sites. Herein, we summarize the first documented incidence of a Turkey Vulture nesting in an abandoned vehicle.

  17. Natural regeneration in abandoned fields following intensive agricultural land use in an Atlantic Forest Island, Brazil

    Full Text Available The time required to regrowth a forest in degraded areas depends on how the forest is removed and on the type of land use following removal. Natural regeneration was studied in abandoned old fields after intensive agricultural land use in areas originally covered by Brazilian Atlantic Forests of the Anchieta Island, Brazil in order to understand how plant communities reassemble following human disturbances as well as to determine suitable strategies of forest restoration. The fields were classified into three vegetation types according to the dominant plant species in: 1 Miconia albicans (Sw. Triana (Melastomataceae fields, 2 Dicranopteris flexuosa (Schrader Underw. (Gleicheniaceae thickets, and 3 Gleichenella pectinata (Willd. Ching. (Gleicheniaceae thickets. Both composition and structure of natural regeneration were compared among the three dominant vegetation types by establishing randomly three plots of 1 x 3 m in five sites of the island. A gradient in composition and abundance of species in natural regeneration could be observed along vegetation types from Dicranopteris fern thickets to Miconia fields. The gradient did not accurately follow the pattern of spatial distribution of the three dominant vegetation types in the island regarding their proximity of the remnant forests. A complex association of biotic and abiotic factors seems to be affecting the seedling recruitment and establishment in the study plots. The lowest plant regeneration found in Dicranopteris and Gleichenella thickets suggests that the ferns inhibit the recruitment of woody and herbaceous species. Otherwise, we could not distinguish different patterns of tree regeneration among the three vegetation types. Our results showed that forest recovery following severe anthropogenic disturbances is not direct, predictable or even achievable on its own. Appropriated actions and methods such as fern removal, planting ground covers, and enrichment planting with tree species were

    The Mejillones Peninsula, in northern Chile, shows a well-preserved set of beach ridges parallel to the present coast. These beach ridges can be observed up to 20 km inland and at 200 m above sea level. Previous dating performed in fossils extracted from the oldest beach ridges yielded ages of 400 ka (Victor et al., 2011). However, numerical ages for younger beach ridges have not been determined, therefore a complete time record is not available. InSar data show that the Mejillones Peninsula was uplifted several centimeters during the last two subduction earthquakes (Antofagasta Mw 8.1, 1995 earthquake and the Mw 7.7, 2007 Tocopilla earthquake) occurred in the area (Loveless et al., 2010). A permanent GPS station deployed by CALTECH (http://web.gps.caltech.edu/~jeff/andes/) in this peninsula has measured a coseismic uplift during the 2007 Tocopilla earthquake. This data suggest that the beach ridges were abandoned as a consequence of coseismic uplift during great subduction earthquakes and therefore they represent the long-term record of past earthquakes. In order to prove this hypothesis we excavated five trenches across the beach ridges. Our idea is to look for stratigraphic evidence of the abandonment mechanism and to collect samples for dating the beach ridges using the method of optically stimulated luminescence (OSL). The ages will be used to estimate long-term uplift rate and temporal variation of this rate. By confronting short-term uplift rate provided by GPS data with long-term rate we hope to know what it is the amount of the coseismic slip that remain in the geological record.

    Mercury mining was a large and thriving industry during the last century in Asturias (NW Spain). At Brañalamosa, mining activity introduced significant quantities of wastes in spoil heaps located close to the mining operations. In these mining wastes, in addition to mercury, high concentrations of other potentially dangerous elements like As have been found. As a consequence, pollution and dereliction of the local environment occurred. This paper focuses on the environmental impact of these old mining operations and describes a preliminary assessment of the extent of contamination. This includes analytical data from systematic sampling of soils, stream sediments, wastes from spoil heaps, water and herbaceous plants in areas affected by mining activities. The potential risk that spoil materials imply for human health and the environment is documented on the basis of the application of EPA Risk Assessment methodology.

    The relationship of measured or modelled Cd concentrations in soil, house dust and available to plants with human urinary Cd concentrations were assessed in a population living around a Cd/Pb/Zn smelter in the UK. Modelled air concentrations explained 35% of soil Cd variation indicating the smelter contributed to soil Cd loads. Multi-variate analysis confirmed a significant role of biological and life-style factors in determining urinary Cd levels. Significant correlations of urinary Cd with soil, house dust and modelled plant available Cd concentrations were not, however, found. Potential reasons for the absence of clear relationships include limited environmental contact in urban populations; the role of undefined factors in determining exposure; and the limited spatial scope of the survey which did not sample from the full pollution gradient. Further, the absence of any significant relationship indicates that environmental measures provide limited advantage over atmospheric model outputs for first stage human exposure assessment. - Highlights: > Environmental measurements indicate smelter pollution of a surrounding urban area. > Life-style and biology influenced U-Cd more than measured environmental levels. > Limited contact with outdoor environments may limit Cd uptake in urban populations. > Better life-style data could improve the attribution of human Cd exposure routes. > Measured Cd levels provide limited added exposure insight over dispersion models. - Measured and modelled environmental cadmium concentrations provide limited additional explanation of human urinary cadmium concentrations.

    This work presents a method for optimizing the itinerary of work over rigs, i.e., the search for the route of minimum total cost, and demonstrates the importance of the dynamics of reservoir behaviour. The total cost of a route includes the rig expenses (transport, assembly and operation), which are functions of time and distances, plus the losses of revenue in wells waiting for the rig, which are also dependent of time. A reservoir simulator is used to evaluate the monetary influence of the well shutdown on the present value of the production curve. Finally, search algorithms are employed to determine the route of minimal cost. The Simulated Annealing algorithm was also successful in optimizing the distribution of a list of wells among different work over rigs. The rational approach presented here is recommended for management teams as a standard procedure to define the priority of wells scheduled for work over. (author)

    As more Alberta oil and gas fields become depleted, attention is being given to development of economically and environmentally sound abandonment procedures. The objective of this study was to identify and assess residual internal and external contaminants associated with abandoned pipelines, particularly those to be abandoned in place. Circumstances which might increase the risk of contaminant release, and other issues relating to residual pipeline contaminants, were also identified. It was found that there are thousands of different substances which could potentially be associated with abandoned pipelines. A wide range in the potential quantities of residual contaminants was also found. Of the issues identified, the effectiveness of pipeline pigging and cleaning procedures prior to abandonment was the most critical determinant of the potential quantities of residual contaminants. However, a number of trace contaminants, such as PCBs (Polychlorinated Biphenyls) and NORMs (Naturally Occurring Radioactive Materials) may remain after thorough cleaning. A brief review of the legislation and regulations from a number of jurisdictions shows that pipeline abandonment has only recently become an issue of concern. Regulations specific to abandonment are lacking, and more general regulations and guidelines are being applied on a contaminant-specific basis, or in terms of waste disposal requirements.

  8. A Novel Abandoned Object Detection System Based on Three-Dimensional Image Information

    2015-03-01

    Full Text Available A new idea of an abandoned object detection system for road traffic surveillance systems based on three-dimensional image information is proposed in this paper to prevent traffic accidents. A novel Binocular Information Reconstruction and Recognition (BIRR algorithm is presented to implement the new idea. As initial detection, suspected abandoned objects are detected by the proposed static foreground region segmentation algorithm based on surveillance video from a monocular camera. After detection of suspected abandoned objects, three-dimensional (3D information of the suspected abandoned object is reconstructed by the proposed theory about 3D object information reconstruction with images from a binocular camera. To determine whether the detected object is hazardous to normal road traffic, road plane equation and height of suspected-abandoned object are calculated based on the three-dimensional information. Experimental results show that this system implements fast detection of abandoned objects and this abandoned object system can be used for road traffic monitoring and public area surveillance.

  9. Microbial Nitrogen-Cycle Gene Abundance in Soil of Cropland Abandoned for Different Periods.

    Directory of Open Access Journals (Sweden)

    Huhe

    Full Text Available In Inner Mongolia, steppe grasslands face desertification or degradation because of human overuse and abandonment after inappropriate agricultural management. The soils in these abandoned croplands exist in heterogeneous environments characterized by widely fluctuating microbial growth. Quantitative polymerase chain reaction analysis of microbial genes encoding proteins involved in the nitrogen cycle was used to study Azotobacter species, nitrifiers, and denitrifiers in the soils from steppe grasslands and croplands abandoned for 2, 6, and 26 years. Except for nitrifying archaea and nitrous oxide-reducing bacteria, the relative genotypic abundance of microbial communities involved in nitrogen metabolism differed by approximately 2- to 10-fold between abandoned cropland and steppe grassland soils. Although nitrogen-cycle gene abundances varied with abandonment time, the abundance patterns of nitrogen-cycle genes separated distinctly into abandoned cropland versus light-grazing steppe grassland, despite the lack of any cultivation for over a quarter-century. Plant biomass and plant diversity exerted a significant effect on the abundance of microbial communities that mediate the nitrogen cycle (P < 0.002 and P < 0.03, respectively. The present study elucidates the ecology of bacteria that mediate the nitrogen cycle in recently abandoned croplands.

    The reduction of the demand on space for settlement and traffic as well as the improvement of cities and rural settlement structures are the most important key questions and challenges of current environmental policy. An intelligent utilisation of the limited resource space is not only related with positive effects of soil protection (Protection of the ''Green Field''). Measures for estate development on industrial, business and settlement fallow grounds contribute to support a long-lasting city development as well to an economic development. In order to improve the re-integration of pre-used land holdings into the real estate business appropriate legal, planning, financial, tax and incentive instruments are required as well as supplemental measures and activity fields like tradable space certification rights, model projects, research incentives, an optimised space management and improved public work. In the frame of this symposium experts report on their experience in the field of space reactivation of large industrial sites and allow for a discussion of their risks, chances and the resulting challenges. A main focus of the conference programme will be the affects of the present European legal guidelines on water and soil protection. (orig.)

  11. Well Integrity and Sealing in CO2 Sequestration Wells

    2009-12-01

    CO2 sequestration is a cost-effective and safe way to help mitigate climate change. Sustained well integrity and zonal isolation of CO2 by cement for the required 1000 year trapping period may be challenging. Some researchers report that cement fails when exposed to CO2 leading to potential leakage into the atmosphere or other underground zones. Others show cement samples from 30-50 year old CO2 wells that maintain the well’s sealing integrity, even though carbonization was found. This presentation provides reasons likely for this disparity between research lab test results and actual well performance data along with best practices to provide efficient cement-based systems for maintaining CO2 containment in storage and EOR (enhanced oil recovery) reservoirs. This discussion includes the geochemical conditions surrounding wells and the positive, long-term effects on cement durability, sealing integrity, and the protection of well casing from CO2 induced corrosion. Also discussed are recent laboratory results testing cement samples surrounded by formation material treated at two different downhole conditions. In one case the cement specimens were treated with a 40% humid CO2 at 140°F and 2000 psi whereas in the second case they were treated with saturated CO2 in water at 200°F and 2000 psi for various time intervals. Results show that samples of carefully designed cement systems had carbonization without any sign of loss of mechanical or sealing integrity which could lead to zonal isolation and well integrity failures. We also will report on a new lab method proposed to determine CO2 sealing performance by cement in a relatively short time period compared to previous methods. In summary, we will discuss a comprehensive approach that may be taken to help ensure longer term effective well integrity and CO2 containment in new CO2 wells and remedial solutions for old wells and for plugging and abandoning wells.

  14. Opiate written behavioral agreements: a case for abandonment.

    2014-01-01

    Written behavioral agreements (WBAs) are gaining popularity as part of the effort to manage the alarming increase in prescription drug abuse. The rationale for increased use of WBAs in managing patients with chronic pain is that they are believed to increase adherence to agreed-upon behaviors, reduce addiction to or diversion of prescription drugs, and satisfy informed consent requirements. However, there are no high-quality data to support their widespread use in any of these areas. The evidence used to support the use of WBAs is insufficient to justify their unfairness and the high risk of harm they pose to the doctor-patient relationship. Instead, we contend that WBAs are being used to provide leverage for severing relationships with some of our most challenging patients. We propose that physicians treating patients for chronic pain abandon the use of WBAs. Alternatives include open communication, detailed informed consent processes, carefully documented discussions, and most important, commitment to ongoing relationships even with difficult patients.

  15. Design Parameters for Abandoned Dumpsite Soil as Liner Material

    Full Text Available This paper presents the findings of laboratory tests that were carried out on abandoned dumpsite soil from Orita-Aperin, Ibadan, and Southwestern Nigeria, to determine its potentiality as hydraulic barrier. Three soil samples were collected (labeled AB1 - AB3 and compacted at –2, 0, 2 and 4% of optimum moisture content using four compactive energy levels namely reduced Proctor (RP, Standard Proctor (SP, West African Standard (WAS and modified Proctor (MP. The design parameters namely: hydraulic conductivity, volumetric shrinkage and unconfined compressive strength showed appreciable variations in their respective values as moulding water contents and compactive efforts were varied. The soil samples studied had hydraulic conductivity that was less than or equal to 1 x 10-7cm/s provided that: the initial dry unit weight is greater than or equal to 16.48 kN/m3; the initial degree of saturation is greater than or equal to 85%; compaction is carried out at a compactive effort greater than or equal to that of the standard Proctor. Hence, the samples can be used as hydraulic barrier in waste containment structure.

  16. How adoption speed affects the abandonment of cultural tastes.

    Products, styles, and social movements often catch on and become popular, but little is known about why such identity-relevant cultural tastes and practices die out. We demonstrate that the velocity of adoption may affect abandonment: Analysis of over 100 years of data on first-name adoption in both France and the United States illustrates that cultural tastes that have been adopted quickly die faster (i.e., are less likely to persist). Mirroring this aggregate pattern, at the individual level, expecting parents are more hesitant to adopt names that recently experienced sharper increases in adoption. Further analysis indicate that these effects are driven by concerns about symbolic value: Fads are perceived negatively, so people avoid identity-relevant items with sharply increasing popularity because they believe that they will be short lived. Ancillary analyses also indicate that, in contrast to conventional wisdom, identity-relevant cultural products that are adopted quickly tend to be less successful overall (i.e., reduced cumulative adoption). These results suggest a potential alternate way to explain diffusion patterns that are traditionally seen as driven by saturation of a pool of potential adopters. They also shed light on one factor that may lead cultural tastes to die out.

    In Italy ore research and exploitation have been nearly exhausted since the end of the last century, and have left on the land a huge amount of mine waste, therefore provoking evident environmental damage including surface and groundwater, soils, vegetation and the food chain, and a potential threat to human health. The main processes occurring at these sites are: rock disgregation, fragments migration, dust dispersion, oxidation (Eh>250mV), acidification (pHlevels. The results obtained suggest that the abandoned mine sites represent actual natural laboratories where to experiment new opportunities for restoration of anthropogenically contaminated areas, and to study new pedogenetic trends from these peculiar parent materials. Moreover, plants growing on these substrates are genetically adapted to metal-enriched soils, and therefore may be utilized in phytoremediation of contaminated sites. Furthermore, the institution of natural parks in these areas could enhance their educational and scientific value, contributing in the meantime to general population amusement and recreation. Finally, it is the occasion for soil scientists to submit to the scientific community new classification proposals of this new kind of soils. Key-words: mine waste, heavy metals, phytoremediation, soil genesis, soil classification

  18. Psychoanalysis and the brain - why did freud abandon neuroscience?

    Science.gov (United States)

    Northoff, Georg

    2012-01-01

    Sigmund Freud, the founder of psychoanalysis, was initially a neuroscientist but abandoned neuroscience completely after he made a last attempt to link both in his writing, "Project of a Scientific Psychology," in 1895. The reasons for his subsequent disregard of the brain remain unclear though. I here argue that one central reason may be that the approach to the brain during his time was simply not appealing to Freud. More specifically, Freud was interested in revealing the psychological predispositions of psychodynamic processes. However, he was not so much focused on the actual psychological functions themselves which though were the prime focus of the neuroscience at his time and also in current Cognitive Neuroscience. Instead, he probably would have been more interested in the brain's resting state and its constitution of a spatiotemporal structure. I here assume that the resting state activity constitutes a statistically based virtual structure extending and linking the different discrete points in time and space within the brain. That in turn may serve as template, schemata, or grid for all subsequent neural processing during stimulus-induced activity. As such the resting state' spatiotemporal structure may serve as the neural predisposition of what Freud described as "psychological structure." Hence, Freud and also current neuropsychoanalysis may want to focus more on neural predispositions, the necessary non-sufficient conditions, rather than the neural correlates, i.e., sufficient, conditions of psychodynamic processes.

    One of the concerns during the planning phase of an exploratory offshore well drilling is the possibility of occurrence of a shallow gas accumulation. In spite of being a rare event, taking into account that an event like this can have disastrous consequences, the cares to work with that type of incident cannot be despised. As example, in 2003, during the operations in the extension well 3-ELPS-15D-SPS, it happened the uncontrolled influx of water and gas to the bottom of the sea: the annular space between the 30'' and 13 3/8'' casings was not filled out with cement, allowing the flow from a shallow permeable interval to the bottom of the sea through the wellhead's cement return orifices, generating the need of an corrective action to make the abandonment of the well in accordance with the Regulation of Abandonment of Wells existent in Brazil. This work presents the mechanical conditions of the interval close to the wet wellhead of the 3-ELPS-15D-SPS, enumerating the sequence of operations accomplished to solve the problem. (author)

    2013-05-01

    Full Text Available Fire is a natural factor in the evolution of Earth ecosystems. Due to land abandonment wildfire are widespread in Mediterranean Type Ecosystems, which contribute to increase the soil erosion rates. Fire is also found in recently abandoned citrus orchards due to the quick vegetation recovery and the dry biomass found after 2 years of abandonment. Rainfall simulation experiments (1 hour at 45 mm h-1 in a plot of 0.25 m2 show that although land abandonment on irrigated citrus orchards reduces the soil losses to very low values, the fire increase runoff and soil erosion. Water and soil losses are much lower in the fire-affected plots than on the cultivated ones due to the use of herbicides.

    2015-12-01

    California currently ranks third in oil production by U.S. state and more than 200,000 wells have been drilled in the state. Oil and gas wells provide a potential pathway for subsurface migration, leading to groundwater contamination and emissions of methane and other fluids to the atmosphere. Here we compile available public databases on oil and gas wells from the California Department of Conservation's Division of Oil, Gas, and Geothermal Resources, the U.S. Geological Survey, and other state and federal sources. We perform geospatial analysis at the county and field levels to characterize depths, producing formations, spud/completion/abandonment dates, land cover, population, and land ownership of active, idle, buried, abandoned, and plugged wells in California. The compiled database is designed to serve as a quantitative platform for developing field-based groundwater and air emission monitoring plans.

  4. Releasing mother's burdens: child abandonment and retrieval in Madrid, 1890-1935.

    Revuelta Eugercios, Bárbara A

    2012-01-01

    In nineteenth-century Europe, the foundling hospital grew beyond its traditional purpose of mitigating the shame of unwed mothers by also permitting widows, widowers, and poor married couples to abandon their children there temporarily. In the Foundling Hospital of Madrid (FHM), this new short-term abandonment could be completely anonymous due to the implementation of a wheel—a device on the outside wall of the institution that could be turned to place a child inside—which remained open until 1929. The use of survival-analysis techniques to disentangle the determinants of retrieval in a discrete framework reveals important differences in the situations of the women who abandoned their children at the FHM, partly depending on whether they accessed it through the Maternity Hospital after giving birth or they accessed it directly. The evidence suggests that those who abandoned their children through the Maternity Hospital retrieved them only when they had attained a certain degree of economic stability, whereas those who abandoned otherwise did so just as soon as the immediate condition prompting the abandonment had improved.

  5. Microbial Community and Greenhouse Gas Fluxes from Abandoned Rice Paddies with Different Vegetation.

    The area of rice paddy fields has declined continuously in East Asian countries due to abandonment of agriculture and concurrent socioeconomic changes. When they are abandoned, rice paddy fields generally transform into wetlands by natural succession. While previous studies have mainly focused on vegetation shifts in abandoned rice paddies, little information is available about how these changes may affect their contribution to wetland functions. As newly abandoned fields proceed through succession, their hydrology and plant communities often change. Moreover, the relationships between these changes, soil microbial characteristics, and emissions of greenhouse gasses are poorly understood. In this study, we examined changes over the course of secondary succession of abandoned rice paddies to wetlands and investigated their ecological functions through changes in greenhouse gas fluxes and microbial characteristics. We collected gas and soil samples in summer and winter from areas dominated by Cyperaceae, Phragmites, and Sphagnum in each site. We found that CO2 emissions in summer were significantly higher than those in winter, but CH4 and N2O emission fluxes were consistently at very low levels and were similar among seasons and locations, due to their low nutrient conditions. These results suggest that microbial activity and abundance increased in summer. Greenhouse gas flux, soil properties, and microbial abundance were not affected by plant species, although the microbial community composition was changed by plant species. This information adds to our basic understanding of the contribution of wetlands that are transformed from abandoned rice paddy systems.

    The Bienener Altrhein is an abandoned channel of the Lower Rhine (Germany). Following a late 16th century abandonment event, the channel was disconnected from the main stream and the oxbow lake gradually filled with 8 meters of flood deposits. This process still continues today. During annual floods, a limited proportion of overbank discharge is routed across the oxbow lake. Large floods produce individual flood layers, which are visually recognized in the sedimentary sequence. Based on the sedimentary characteristics of these event layers, we created a ~450-year flood chronology for the Lower Rhine. Laser-diffraction grain size measurements were used to assess relative flood magnitudes for individual flood event layers. Continuous sampling at a ~2 cm interval provided a high-resolution record, resolving the record at an annual scale. Standard descriptive techniques (e.g., mean grain size, 95th percentile, % sand) and the more advanced 'end member modelling' were applied to zoom in on the coarse particle bins in the grain size distributions, which are indicative of higher flow velocities. The most recent part of the record was equated to modern discharge measurements. This allows to establish relations between deposited grain size characteristics in the abandoned channel and flood magnitudes in the main river. This relation can also be applied on flood event layers from previous centuries, for which only water level measurements and historical descriptions exist. This makes this method relevant to expand data series used in flood frequency analysis from 100 years to more than 400 years. To date event-layers in the rapidly accumulated sequence, we created an age-depth model that uses organic content variations to tune sedimentation rates between the known basal and top ages. No suitable identifiable organic material for radiocarbon dating was found in the cores. Instead, palynological results (introduction of agricultural species) and palaeomagnetic secular

    Full Text Available Accumulation of high concentrations of heavy metals in environments can cause many human health risks and serious ecological problems. Nowadays, bioremediation using microorganisms is receiving much attention due to their good performance. The aim of this work is to investigate heavy metals resistance and bioaccumulation potential of actinobacteria strains isolated from some abandoned mining areas. Analysis of mining residues revealed that high concentration of zinc “Zn” was recorded in Sidi Bouatman, Arbar, and Bir Nhass mining residues. The highest concentration of lead “Pb” was found in Sidi Bouatman. Copper “Cu,” cadmium “Cd,” and chromium “Cr” were found with moderate and low concentrations. The resistance of 59 isolated actinobacteria to the five heavy metals was also determined. Using molecular identification 16S rRNA, these 27 isolates were found to belong to Streptomyces and Amycolatopsis genera. The results showed different levels of heavy metal resistance; the minimum inhibitory concentration (MIC recorded was 0.55 for Pb, 0.15 for Cr, and 0.10 mg·mL−1 for both Zn and Cu. Chemical precipitation assay of heavy metals using hydrogen sulfide technic (H2S revealed that only 27 isolates have a strong ability to accumulate Pb (up to 600 mg of Pb per g of biomass for Streptomyces sp. BN3.

    Full Text Available The objective of the work was to evaluate establishment and forage production of native grasses with application of biosolids, a byproduct of waste-water treatment, at an abandoned field, in Ejido Nuevo Delicias, Chihuahua, Mexico. Four biosolids rates from 0 (control to 30 dry Mg ha−1 and two methods of application, surface applied (BioSur and soil incorporated (BioInc, were evaluated. Seedbed preparation included plowing and harrowing before rainfall. Field plots of 5 × 5 m were manually sown with a mix of blue grama (Bouteloua gracilis (50% and green sprangletop (Leptochloa dubia (50% in early August 2005. Experimental design was a randomized block with a split plot arrangement. Grass density, height, and forage production were estimated for three years. Data were analyzed with mixed linear models and repeated measures. Green sprangletop density increased under all biosolids rates regardless of method of application, while blue grama density slightly decreased. Biosolids were more beneficial for green sprangletop height than for blue grama height. Blue grama forage production slightly increased, while green sprangletop forage production increased the most at 10 Mg ha−1 biosolids rate under BioSur method. It was concluded that BioSur application at 10 and 20 Mg ha−1 rates had positive effects on the establishment and forage production of native grasses, especially green sprangletop.

    Full Text Available We consider an overloaded multiclass nonidling first-in-first-outsingle-server queue with abandonment. The interarrival times, servicetimes, and deadline times are sequences of independent and identically,but generally distributed random variables. In prior work, Jennings andReed studied the workload process associated with this queue. Undermild conditions, they establish both a functional law of large numbersand a functional central limit theorem for this process. We build on thatwork here. For this, we consider a more detailed description of thesystem state given by K finite, nonnegative Borel measures on thenonnegative quadrant, one for each job class. For each time and jobclass, the associated measure has a unit atom associated with each jobof that class in the system at the coordinates determined by what arereferred to as the residual virtual sojourn time and residual patiencetime of that job. Under mild conditions, we prove a functional law oflarge numbers for this measure-valued state descriptor. This yieldsapproximations for related processes such as the queue lengths andabandoning queue lengths. An interesting characteristic of theseapproximations is that they depend on the deadline distributions intheir entirety.

    Full Text Available Este trabalho investiga o abandono de crianças no Recife, geradas nas relações castas e lascivas, sacramentadas e duvidosas, entre os anos de 1789 a 1832. Como provas da "fraqueza moral" ou "fruto da miséria", eram os "miúdos" abandonados às intempéries e aos animais carnívoros, deixados em portas de casas e igrejas, ruas e becos quando foi instituída a Casa dos Expostos que visava acolher e criá-los, salvaguardar a honra de moças de família e desestimular o infanticídio. Paradoxalmente, os discursos, as interdições e a normatização relativas à sexualidade e à religiosidade que regulavam a vida dos colonos foi também o esteio para o costume de se abandonar bebês. Os sinais e fragmentos desses "pequenos" são encontrados nos livros de batismos que falam de crianças sem família, vidas excedentes e indesejadas, como fica patente no alto índice de mortalidade dentro da Instituição.This work investigates the abandonment of children born from chaste and lascivious, blessed and doubtful, relationships in Recife between 1789 and 1832. As live evidence of the moral "weakness" or as a "fruit of misery", they were abandoned to bad weather conditions and carnivorous animals, left at houses' and churches' doors, on the streets and alleys, until the House of the Bare was finally created, mainly to shelter and rear them, to protect the honor of the well-born women and to discourage the infanticide. Paradoxically, the discourses, interdictions and the normalization relating to sexuality and religiousness of the settlers' lives were also a support for the habit of abandoning children. The traces and fragments of these "little ones" are found in baptism books which tell us about boys and girls without families, exceeding and undesired lives, as the high rate of mortality in that institution indicates.

  14. Design of the Bottom-up Innovation project - a participatory, primary preventive, organizational level intervention on work-related stress and well-being for workers in Dutch vocational education

    Science.gov (United States)

    2013-01-01

    Background In the educational sector job demands have intensified, while job resources remained the same. A prolonged disbalance between demands and resources contributes to lowered vitality and heightened need for recovery, eventually resulting in burnout, sickness absence and retention problems. Until now stress management interventions in education focused mostly on strengthening the individual capacity to cope with stress, instead of altering the sources of stress at work at the organizational level. These interventions have been only partly effective in influencing burnout and well-being. Therefore, the “Bottom-up Innovation” project tests a two-phased participatory, primary preventive organizational level intervention (i.e. a participatory action approach) that targets and engages all workers in the primary process of schools. It is hypothesized that participating in the project results in increased occupational self-efficacy and organizational efficacy. The central research question: is an organization focused stress management intervention based on participatory action effective in reducing the need for recovery and enhancing vitality in school employees in comparison to business as usual? Methods/Design The study is designed as a controlled trial with mixed methods and three measurement moments: baseline (quantitative measures), six months and 18 months (quantitative and qualitative measures). At first follow-up short term effects of taking part in the needs assessment (phase 1) will be determined. At second follow-up the long term effects of taking part in the needs assessment will be determined as well as the effects of implemented tailored workplace solutions (phase 2). A process evaluation based on quantitative and qualitative data will shed light on whether, how and why the intervention (does not) work(s). Discussion “Bottom-up Innovation” is a combined effort of the educational sector, intervention providers and researchers. Results will

    Currently, there are approximately 150 uranium mines in Europe at various stages of either operation, development, decommissioning, restoration or abandonment (wise-uranium.com). The particulate matter comprising the mounds of waste rock and mill tailings poses a risk to human health through the inadvertent ingestion of particles contaminated with uranium and thorium, and their decay products, which exposes recipients to the dual toxicity of heavy elements and their radioactive emissions. We investigated the bioaccessibility of 238U, 232Th and 206,214,210Pb in particulate samples taken from a contaminated, abandoned uranium mine in South West England. Sampling included a mine shaft, dressing floor and waste heap, as well as soils from a field used for grazing. The contaminants were extracted using the in-vitro Unified Bioaccessibility Research Group of Europe Method (UBM) in order to mimic the digestion processes in the human stomach (STOM) and the combined stomach and gastrointestinal tract (STOM+INT). Analyses of concentrations of U, Th and Pb in the extracts were by ICP-MS and the activity concentrations of radionuclides were determined on the same particles, before and after extraction, using gamma spectroscopy. 'Total' concentrations of U, Th and Pb for all samples were in the range 57 to 16,200, 0.28 to 3.8 and 69 to 4750 mg kg-1, respectively. For U and Pb the concentrations in the STOM fraction were lower than the total and STOM+INT fractions were even lower. However, for Th the STOM+INT fractions were higher than the STOM due to the presence of Th carbonate species within the gastrointestinal fluid. Activity concentrations for 214Pb and 210Pb, including total, STOM and STOM+INT, were in the range 180 to <1 Bq g-1 for the dressing floor and waste heap and 18 to <1 Bq g-1 for the grazing land. Estimates of the bioaccessible fractions (BAFs) of 238U in the most contaminated samples were 39% and 8% in the STOM and STOM+INT, respectively, whereas the respective

    The Almadén area (Spain) is known for its high natural mercury background as well as for the anthropogenic impact due to mining activities. After the end of these activities, appropriate alternative use of the soil has to be found, and agricultural activities stand out as an environmentally-friendly and potentially profitable alternative, giving to the soil a sustainable use without risks for human or animal health according to current legislation. Experiments performed at different scales (involving hydroponics, growth in pots and lysimeters) allow recommendations to be made regarding the adequacy of cultivation of different crops for animal or human consumption before they are sown in the field. Regarding crops for animal feeding, mercury accumulation in vegetative organs represents a higher potential risk for animals. Nevertheless, seeds and fruits can be used, both for human and animal consumption. Finally, this work will lead the way to obtain a scientific basis for elaborating a list of recommendations on sustainable and safe alternative land use, according to current international legislation.

    Farmland abandonment (FLA) could be defined as the cessation of agricultural activities on a given surface of land (Pointereau et al., 2008). FLA, often associated with social and economic problems in rural areas, has significant environmental consequences. During the 1990s, millions of hectares of farmland in the new EU Member States, from Central and Eastern Europe, were abandoned as a result of the transition process from centralized and planned to market economy. The policy tools adopted gradually within the Common Agricultural Policy of the European Union (EU CAP), as well as the EU environmental and structural policies, aimed to prevent further expansion of this phenomenon and to facilitate the revival of the agriculture land, being abandoned (ComReg 1122/2009). The Agri-Environment (AGRI-ENV) component of the Core Information Service (CIS), developed within the scope of the FP7-funded project "geoland2" were designed to support the agricultural user community at pan-European and national levels by contributing to the improvement of more accurate and timely monitoring of the status of agricultural land use in Europe and its change. The purpose of the product 'Farmland abandonment', as part of the AGRI-ENV package, is to detect potentially abandoned agriculture land, based on multi-annual SPOT data with several acquisitions per year. It provides essential independent information on the status of the agricultural land as recorded in the Land Parcel Identification System (LPIS), which is one of the core instruments of the implementation of CAP. The production line is based on object-based image analysis and benefits from the extensive availability of Biophysical parameters derived from the satellite data (geoland2). The method detects/tracks those land (or so-called reference) parcels in the LPIS, holding significant amount of land agriculture found as potentially abandoned. Reference parcels with such change are flagged and reported, enabling the National

    For decades, hazard assessments for environmental chemicals have used intra-gastric gavage to assess the effects of 'oral' exposures. It is now widely used--and in some cases required--by US federal agencies to assess potential toxicity of endocrine disrupting chemicals (EDCs). In this review we enumerate several reasons why gavage is not appropriate for the assessment of EDCs using bisphenol A (BPA) as a main example. First, whereas human dietary exposures interact with the oral mucosa, gavage exposures avoid these interactions, leading to dramatic differences in absorption, bioavailability and metabolism with implications for toxicokinetic assumptions and models. Additionally, there are well acknowledged complications associated with gavage, such as perforation of the esophagus that diminish its value in toxicological experiments. Finally, the gavage protocol itself can induce stress responses by the endocrine system and confound the assessment of EDCs. These serious flaws have not been taken into account in interpreting results of EDC research. We propose the exploration of alternatives to mimic human exposures when there are multiple exposure routes/sources and when exposures are chronic. We conclude that gavage may be preferred over other routes for some environmental chemicals in some circumstances, but it does not appropriately model human dietary exposures for many chemicals. Because it avoids exposure pathways, is stressful, and thus interferes with endocrine responses, gavage should be abandoned as the default route of administration for hazard assessments of EDCs.

    Various biomonitoring approaches were tested in the field to assess the response of natural periphythic algal communities to chronic metal contamination downstream from an abandoned mine tailings site. The accumulation of cadmium (Cd), copper (Cu), lead (Pb) and zinc (Zn) as well as the production of phytochelatins, the presence of diatom taxa known to tolerate high metal concentrations, diatom diversity and the presence of teratologies were determined. We observed highly significant relationships between intracellular metal and calculated free metal ion concentrations. Such relationships are often observed in laboratory studies but have been rarely validated in field studies. These results suggest that the concentration of metal inside the field-collected periphyton, regardless of its species composition, is a good indicator of exposure and is an interesting proxy for bioavailable metal concentrations in natural waters. The presence of teratologies and metal-tolerant taxa at our contaminated sites provided a clear indication that diatom communities were responding to this metal stress. A multi-metric approach integrating various bioassessment methods could be used for the field monitoring of metal contamination and the quantification of its effects. Highlights: Black-Right-Pointing-Pointer Various approaches for metal contamination biomonitoring were used in the field. Black-Right-Pointing-Pointer Metal accumulation in periphyton is correlated to free ion concentration. Black-Right-Pointing-Pointer Teratologies and metal-tolerant taxa provided a clear indication of metal stress. Black-Right-Pointing-Pointer Stream periphyton shows great potential as a biomonitor of metal contamination.

    Predation is one of the most important drivers of natural selection. In consequence a huge variety of anti-predator defenses have evolved in prey species. Under unpredictable and temporally variable predation pressure, the evolution of phenotypically plastic defensive traits is favored. These "inducible defenses", range from changes in behavior, life history, physiology to morphology and can be found in almost all taxa from bacteria to vertebrates. An important group of model organisms in ecological, evolutionary and environmental research, water fleas of the genus Daphnia (Crustacea: Cladocera), are well known for their ability to respond to predators with an enormous variety of inducible morphological defenses. Here we report on the "twist", a body torsion, as a so far unrecognized inducible morphological defense in Daphnia, expressed by Daphnia barbata exposed to the predatory tadpole shrimp Triops cancriformis. This defense is realized by a twisted carapace with the helmet and the tail spine deviating from the body axis into opposing directions, resulting in a complete abolishment of bilateral symmetry. The twisted morphotype should considerably interfere with the feeding apparatus of the predator, contributing to the effectiveness of the array of defensive traits in D. barbata. As such this study does not only describe a completely novel inducible defense in the genus Daphnia but also presents the first report of a free living Bilateria to flexibly respond to predation risk by abandoning bilateral symmetry.

    Small islands are widely agreed to be vulnerable to human-induced sea-level rise during the 21st century and beyond, with forced abandonment of some low-lying oceanic islands being a real possibility. A regional abandonment of islands in the Chesapeake Bay, USA provides an historical analog of such vulnerability as this has been linked to a mid 19th Century acceleration in relative sea-level rise. Using a case study approach for Holland Island, Maryland, this hypothesis was tested using a range of physical and human historical data. While sea-level rise was the underlying driver, this analysis shows that the abandonment was more complex than a direct response to sea-level rise. Between 1850 and 1900, Holland Island was a booming community and population increased from 37 to 253, with immigration causing the majority of the increase. At the same time, the upland area where people made their homes was steadily diminishing, losing about 15 ha or 38% of the total. After 1900, the island experienced a decrease in population to 169 in 1916, with final abandonment in 1918, with the exception of one family who left by 1920. Final abandonment was triggered by this depopulation as the population fell below a level that could support critical community services, and the community lost faith in their future on Holland Island. It is likely that similar social processes determined the abandonment of the other Chesapeake Bay islands. Looking to the future, it shows that many small low-lying islands could be abandoned due to sea-level rise long before they become physically uninhabitable. (author)

    Cocoa agroforests like the cabrucas of Brazil's Atlantic forest are among the agro-ecosystems with greatest potential for biodiversity conservation. Despite a global trend for their intensification, cocoa agroforests are also being abandoned for socioeconomic reasons especially on marginal sites, because they are incorporated in public or private protected areas, or are part of mandatory set-asides under Brazilian environmental legislation. However, little is known about phylogenetic structure, the processes of forest regeneration after abandonment and the conservation value of former cabruca sites. Here we compare the vegetation structure and composition of a former cabruca 30-40 years after abandonment with a managed cabruca and mature forest in the Atlantic forest region of Espirito Santo, Brazil. The forest in the abandoned cabruca had recovered a substantial part of its original structure. Abandoned cabruca have a higher density (mean ± CI95 %: 525.0 ± 40.3 stems per ha), basal area (34.0 ± 6.5 m2 per ha) and species richness (148 ± 11.5 species) than managed cabruca (96.0 ± 17.7; 24.15 ± 3.9 and 114.5 ± 16.0, respectively) but no significant differences to mature forest in density (581.0 ± 42.2), basal area (29.9.0 ± 3.3) and species richness (162.6 ± 15.5 species). Thinning (understory removal) changes phylogenetic structure from evenness in mature forest to clustering in managed cabruca, but after 30-40 years abandoned cabruca had a random phylogenetic structure, probably due to a balance between biotic and abiotic filters at this age. We conclude that abandoned cocoa agroforests present highly favorable conditions for the regeneration of Atlantic forest and could contribute to the formation of an interconnected network of forest habitat in this biodiversity hotspot.

    Abandoned gas wells in western Canada often leak gas to the surface. An experimental study was conducted in order to determine the possibility of using an asphalt-in-water emulsion as sealant for abandoned leaky wells. This is considered a more efficient and cost-effective method to the conventional cement grout barrier. The study objective was to test this new sealant technology proposed by Seal-MastR and to examine the effect of those parameters affecting the placement and fixing of an emulsion in the near well bore matrix, thereby hindering the flow of water or gas. Two types of experiments were conducted as part of this study. The mechanism of the emulsion penetration into the porous matrix was studied making observations of the process in a transparent core holder. The process was investigated using a steel core holder that allows injection of the emulsion at actual well pressures. It was concluded that the asphalt-in-water emulsion technology can be used with success for sealing abandoned gas-leaking wells or water-producing formations. The study also proposed recommendations for field application and suggested areas for further research to improve the process, such as finding the optimum concentration for the surfactant solution pre-flush that would yield the highest penetration, and testing the emulsion in oil-wet or partially oil-wet formation. 4 refs., 3 tabs., 19 figs.

    The closure and decay of industrial activity involving mining has scarred the landscape of urban areas and geo-hazards posed by subsurface cavities are ubiquitous throughout Europe. Features of concern consist of natural solution cavities (e.g. swallow holes and sinkholes in limestone gypsum and chalk) and man-made cavities (mine workings, shafts) in a great variety of post mining environments, including coal, salt, gypsum, anhydrite, tin and chalk. These problems restrict land utilisation, hinder regeneration, pose a threat to life, seriously damage property and services and blight property values. This paper outlines the application of microgravity techniques to characterise abandoned mining hazard in case studies from Coal, Chalk and Salt Mining environments in the UK. (authors)

    The abandonment of olive orchards is a phenomenon of great importance triggered mainly by economic and social causes. The aim of this study was to investigate some chemical, biochemical, and microbiological properties in a soil of a southern olive grove abandoned for 25 years. In order to define the effect of the long-term land abandonment on soil properties, an adjacent olive grove managed according to extensive practices was taken as reference (essentially minimum tillage and no fertilization). Soil organic matter, total nitrogen, and pH were significantly higher in the abandoned olive grove due to the absence of tillage and the natural inputs of organic matter at high C/N ratio which, inter alia, increased the number of cellulolytic bacteria and stimulated the activity of β -glucosidase, an indicator of a more advanced stage of soil evolution. The soil of the abandoned olive orchard showed a lower number of total bacteria and fungi and a lower microbial diversity, measured by means of the Biolog method, as a result of a sort of specialization trend towards low quality organic substrates. From this point of view, the extensive cultivation management seemed to not induce a disturbance to microbiological communities.

    To determine whether ambulatory psychotherapy targeted to abandonment experiences and fears can reduce suicidality and improve outcome in borderline patients referred to the emergency room with major depressive disorder and self-destructive behavior severe enough to require medical/surgical treatment and a brief psychiatric hospitalization. A total of 170 subjects were randomized at hospital discharge into three treatment groups: treatment as usual (TAU), abandonment psychotherapy delivered by certified psychotherapists, and abandonment psychotherapy delivered by nurses. Assessments were performed before randomization and at 3-month follow-up. Continued suicidality and other outcome measures were significantly worse in the treatment-as-usual as compared to both abandonment psychotherapy groups, but there were no differences between the two psychotherapy groups. These results suggest the efficacy of manualized psychotherapy that specifically targets the abandonment fears and experiences that are so common as precipitants to suicidal and self-destructive acts in borderline patients. It does not appear that formal psychotherapy training is associated with better outcomes.

    Full Text Available Different land cover types are related to different levels of fire hazard through their vegetation structure and fuel load composition. Therefore, understanding the relationships between landscape changes and fire behavior is of crucial importance for developing adequate fire fighting and fire prevention strategies for a changing world. In the last decades the abandonment of agricultural lands and pastoral activities has been the major driver of landscape transformations in Mediterranean Europe. As agricultural land abandonment typically promotes an increase in plant biomass (fuel load, a number of authors argue that vegetation succession in abandoned fields and pastures is expected to increase fire hazard. In this short paper, based on 28 493 fires in Sardinia (Italy in the period 2001–2010, we show that there is no evidence of increased probability of fire ignition in abandoned rural areas. To the contrary, in Sardinia the decreased human impact associated with agricultural land abandonment leads to a statistically significant decrease of fire ignition probability.

    Artemisia scoparia, Artemisia sacrorum and Artemisia giraldii were three dominant Artemisia species which successive grew in the secondary succession on abandoned land of the Loess Plateau. The succession accompanied the soil moisture steady decrease with field age after their abandonment. To elucidate the relationship between the Artemisia species succession and their drought-adaptation, three dominant species and a contrastive species Artemisia annua (mesophyte), were selected to compare their drought-resistant characteristics, including morphological and anatomical traits of leaf and root. Then physiological responses were investigated in mature plants after drought treatment. The results indicated that three dominant species leaf presented drought-adaptive structures, such as bushy trichomes, transitional or isolateral leaf cells, thick cuticles and epidermal cells. However, A. annua had no leaf traits involved in drought-adaptation. In addition, A. sacrorum and A. giraldii contained large root systems, while A. scoparia and A. annua utilized succulent roots. The physiological responses to drought suggested that A. giraldii had strong regulation in water using strategy, growth, as well as superoxide dismutase and catalase activity. A. sacrorum and A. giraldii could maintain high ascorbate peroxidase activity and malondialdehyde content, while A. scoparia and A. giraldii presented higher peroxidase activity, ascorbate and soluble sugar content. A. annua exhibited high proline and carotenoid contents under drought. The drought-resistant of the four Artemisia species presented the order of A. giraldii > A. sacrorum > A. scoparia > A. annua, which was consistent with their succession on abandoned land.

    2016-01-01

    Full Text Available Usually, traditional methods for investment project appraisal such as the net present value (hereinafter NPV do not incorporate in their values the operational flexibility offered by including a real option included in the project. In this paper, real options, and more specifically the option to abandon, are analysed as a complement to cash flow sequence which quantifies the project. In this way, by considering the existing analogy with financial options, a mathematical expression is derived by using the binomial options pricing model. This methodology provides the value of the option to abandon the project within one, two, and in general n periods. Therefore, this paper aims to be a useful tool in determining the value of the option to abandon according to its residual value, thus making easier the control of the uncertainty element within the project.

    Within the European Union, guidance in the form of a uniform Soil Directive does not exist and member states are left to enact their own legislation governing historic soil contamination. Several historic or "legacy" sites exist in Cyprus - an EU member state with a long history of mining and a significant number of abandoned mining sites. The gold-silver enrichment plant of Mitsero village was abandoned 70 years ago, yet soil samples inside and outside the plant were extremely low in pH, exhibited high leachability of heavy metals and high cyanide levels. Water samples collected from an ephemeral stream located down-gradient of the site contained high levels of heavy metals. Two abandoned open-pit mines (Kokkinopezoula and Mathiatis) were investigated, where elevated metal content in soil samples from the surrounding streams and spoil heaps, and extremely low pH and high metal content in water samples from the mine crater were measured.

    This study presents a new Windows-based program based on GRAM(Groundwater Rebound in Abandoned Mineworkings) model which can analyze the groundwater rebound in abandoned mines. The program consists of the graphic user interface and the simulation engine modules. Intel Parallel Studio XE 2013 and Visual Studio.NET 2010 were used to effectively implement the graphic user interface and the simulation engine modules. The standard formats of input and output files were designed by considering the characteristics of GRAM model. We carried out a case study to analyze groundwater rebound at the Dongwon coal mine, Korea. As a result, we could know that the developed program can provide useful information for predicting the groundwater rebound in abandoned mines.

    Full Text Available Similar to other Asian nations, suburban areas in Japan are characterized by dense intermixtures of residential areas and farmlands. These hybrid rural/urban areas are evaluated negatively in modern planning frameworks. However, mixed rural/urban landscapes may prove advantageous when attempting to reconstruct sustainable wastewater treatment systems. This research examines the potential for abandoned paddy fields to reduce nitrogen (T-N and phosphorous (T-P loads, an increasingly problematic source of eutrophication in many closed water areas, from households in suburban areas. Our results indicate that abandoned paddy fields remaining in mixed urban/rural areas have significant potential to reduce both nitrogen and phosphorous loads. Accordingly, we suggest that abandoned paddy fields can play an important role in reducing pollution loads in mixed urban/rural areas.

    Fires in anthropogenically-dominated landscapes are generally attributed to ecosystem management, agriculture, and policy drivers. In European Russia, fire mainly occurring on agricultural lands, wetlands, and abandoned lands. In the agricultural practice in Russia prescribed fires are believed to increase pasture and hay productivity, suppress trees and shrub expansion, and reduce fire hazards, with fire frequency fire dependent on land use and agricultural practices. The large-scale socio-economic transition since the fall of the Soviet Union has led to changes in land use and land management, including land abandonment and changing agricultural practices. In June 2014, an extensive field campaign was completed in the Smolensk Oblast, located approximately two hundred kilometers west of Moscow on the border with Belarus. Our field sampling was based on circa 1985 Landsat-based forest cover map (Potapov et al., 2014). Points were randomly selected from the non-forested class of the 1985 classification, prior to the collapse of the Soviet Union. Of total field collects, 55% points were sampled on land in either early or late stage of abandonment, 15% from actively cropped fields, and 30% from hay or pasture. Fire frequency was calculated for the 108 field points using 1 km Moderate Resolution Imaging Spectroradiometer (MODIS) active fire data for years 2000-2014. Also we calculated percent of points burned in spring 2014 using 30 m Landsat 8 Operational Land Imager (OLI) data to derive burn scars. Actively cropped fields had lowest burn frequency while abandoned lands - early and late stage abandonment - had highest frequency. Fire frequency was significantly higher on wet soils than dry soils, with no relationship between fire frequency and tree canopy cover. We hypothesize, higher fire frequency on abandoned lands was likely due to greater fuel loads and because of traditional belief in rural Russia that fire is efficient way to suppress tree and shrub expansion.

    Full Text Available In the Nordic countries, child abandonment seems to have been a commonly accepted social tradition until the acceptance of Christianity. When Christian influences reached the Far North, this old practice was gradually criminalized. When the old practice was criminalized by Christian sanctions and norms, the abandoned, murdered or aborted unbaptized children were experienced supernaturally. Their supranormal manifestations are described in Nordic folk beliefs and narratives concerning dead children; in Old Norse sagas, Swedish and Norwegian provincial and ecclesiastical laws and in Finnish runic poetry, all stemming from the Middle Ages.

    1982-01-01

    Coal was last mined in Saginaw County, Michigan in 1950. Water from abandoned mines and from undisturbed coal-bearing beds in the Saginaw Formation is highly mineralized and contains high concentrations of iron. Compared to streams in the area, the water contains higher concentrations of at least 15 constituents including boron, phenol, lithium, strontium, and manganese. Water from abandoned mines and coal-bearing beds is a poor source of water for domestic, public, or agricultural uses. Large amounts of this highly mineralized ground water reaching local streams would have a deleterious effect on surface-water quality.

    Ionising radiation has the ability to induce DNA damage. While the effects of high doses of radiation of short duration have been well documented, the biological effects of long-term exposure to low doses are poorly understood. This study evaluated the clastogenic effects of low dose ionising radiation on a population of bats (Chiroptera) residing in an abandoned monazite mine. Bats were sampled from two chambers in the mine, where external radiation levels measured around 20 microSv/h (low dose) and 100 microSv/h (higher dose), respectively. A control group of bats was sampled from a cave with no detectable radiation above normal background levels. The micronucleus assay was used to evaluate residual radiation damage in binucleated lymphocytes and showed that the micronucleus frequency per 500 binucleated lymphocytes was increased in the lower radiation-exposed group (17.7) and the higher radiation-exposed group (27.1) compared to the control group (5.3). This study also showed that bats exposed to radiation presented with an increased number of micronuclei per one thousand reticulocytes (2.88 and 10.75 in the lower and high radiation-exposed groups respectively) when compared to the control group (1.7). The single-cell gel electrophoresis (comet) assay was used as a means of evaluating clastogenecity of exposure to radiation at the level of individual cells. Bats exposed to radiation demonstrated increased DNA damage as shown by the length of the comet tails and showed an increase in cumulative damage. The results of the micronucleus and the comet assays indicated not only a statistically significant difference between test and control groups (P<0.001), but also a dose-dependent increase in DNA damage (P<0.001). These assays may thus be useful in evaluating the potential clastogenecity of exposure to continuous low doses of ionising radiation.

    In Murcia Region, SE Spain, there are 85 tailing ponds due to intensive mining activities that occurred during last century, especially in Sierra Minera de Cartagena-La Union. Although mining activity was abandoned several decades ago, those tailing ponds with high amounts of heavy metals still remain in the area. The ponds, due to their composition and location, may create environmental risks of geochemical pollution, negatively affecting soil, water, and plant, animal, and human populations, as well as infrastructures. The main objective of this research is to evaluate the restoration possibilities of two representative mining ponds in order to minimize the risk for human and ecosystems. To achieve this objective, two tailing ponds generated by mining activities were selected, El Lirio and El Gorguel. These ponds are representative of the rest of existent ponds in Sierra Minera de Cartagena-La Unión, with similar problems and characteristics. Several techniques and studies were applied to the tailing ponds for their characterization, including: geophysics, geotechnics, geochemical, geological, hydrological, and vegetation studies. In addition, effects of particulate size in the distribution of heavy metals will be used to assess the risk of dispersion of these metals in finest particles. Once the ponds were characterized, they were divided in several sectors in order to apply different amendments (pig slurry and marble waste) to reduce the risk of metal mobility and improve soil quality for a future phytostabilization. It is known that organic amendments promote soil development processes, microbial diversity, and finally, soil ecosystem restoration to a state of self-sustainability. By comparing the results before and after applications we will be able to evaluate the effect of the different amendments on soil quality and their effectively on risk reduction. Finally, plant metal-tolerant species are used to restore vegetation in the ponds, thereby decreasing

    The afforestation of abandoned farmland significantly influences soil organic carbon (OC). However, the dynamics between OC inputs after afforestation and the original OC are not well understood. To learn more about soil OC dynamics after afforestation of farmland, we measured the soil OC content in paired forest and farmland plots in Shaanxi Province, China. The forest plots had been established on farmland 18, 24, 48, 100, and 200 yr previously. The natural (13)C abundance of soil organic matter was also analyzed to distinguish between crop- and forest-derived C in the afforested soils. We observed a nonlinear accumulation of total OC in the 0-80 cm depth of the mineral soil across time. Total soil OC accumulated more rapidly under forest stands aged 18 to 48 yr than under forest stands aged 100 or 200 yrs. The rate of OC accumulation was also greater in the 0-10 cm depth than in the 10-80 cm depth. Forest-derived OC in afforested soils also accumulated nonlinearly across time, with the greatest increase in the 0-20 cm depth. Forest-derived OC in afforest soils accounted for 52-86% of the total OC in the 0-10 cm depth, 36-61% of the total OC in the 10-20 cm depth, and 11-50% of the total OC in the 20-80 cm depth. Crop-derived OC concentrations in the 0-20 cm depth decreased slightly after afforestation, but there was no change in crop-derived OC concentrations in the 20-80 cm depth. The results of our study support the claim that afforestation of farmland can sequester atmospheric CO(2) by increasing soil OC stocks. Changes in the OC stocks of mineral soils after afforestation appear to be influenced mainly by the input of forest-derived C rather than by the loss of original OC.

    At present,as an effective form of public opinion participation,as an important channel for government to know social conditions and public opinions,call-in radio shows focusing on the enhancement of public supervision concerning working style and vocational display have played an important role to promote the government administration according to law,resolve conflicts and promote harmonious society construction.To run this kind of radio shows well,it is suggested that the supervision of public opinion,of the masses and of administration should be set in one body.The supervision of public opinion should be given full play to the initiative of the independent supervision,not only to combine the supervision of the masses,making the public opinion a strong supervision platform,but also to cooperate with the administrative supervision,making it the backbone of the anti-corruption.%现阶段,以舆论监督为主的政风行风热线节目作为群众参与纠风的有效形式,作为政府倾听社情民意的重要渠道,对促进政府依法行政、化解各种社会矛盾、推动社会和谐建设发挥着重要作用。做好政风行风类节目,必须坚持集舆论监督、群众监督和行政监督于一体。舆论监督要充分发挥独立监督的能动性,不仅要与群众监督相结合,使之构建强有力的公共舆论监督平台,也要与行政监督相配合,使之成为反腐倡廉的中坚力量。

    Water repellency is a natural soil property with implications on infiltration, erosion and plant growth. It depends on soil texture, type and amount of organic matter, fungi, microorganisms, and vegetation cover (Doerr et al., 2000). Human activities as agriculture can have implications on soil water repellency (SWR) due tillage and addition of organic compounds and fertilizers (Blanco-Canqui and Lal, 2009; Gonzalez-Penaloza et al., 2012). It is also assumed that SWR has a high small-scale variability (Doerr et al., 2000). The aim of this work is to study the spatial probability of SWR in an abandoned field testing several geostatistical methods, Organic Kriging (OK), Simple Kriging (SK), Indicator Kriging (IK), Probability Kriging (PK) and Disjunctive Kriging (DK). The study area it is located near Vilnius urban area at (54 49' N, 25 22', 104 masl) in Lithuania (Pereira and Oliva, 2013). It was designed a experimental plot with 21 m2 (07x03 m). Inside this area it was measured SWR was measured every 50 cm using the water drop penetration time (WDPT) (Wessel, 1998). A total of 105 points were measured. The probability of SWR was classified in 0 (No probability) to 1 (High probability). The methods accuracy was assessed with the cross validation method. The best interpolation method was the one with the lowest Root Mean Square Error (RMSE). The results showed that the most accurate probability method was SK (RMSE=0.436), followed by DK (RMSE=0.437), IK (RMSE=0.448), PK (RMSE=0.452) and OK (RMSE=0.537). Significant differences were identified among probability tests (Kruskal-Wallis test =199.7597 p<0.001). On average the probability of SWR was high with the OK (0.58±0.08) followed by PK (0.49±0.18), SK (0.32±0.16), DK (0.32±0.15) and IK (0.31±0.16). The most accurate probability methods predicted a lower probability of SWR in the studied plot. The spatial distribution of SWR was different according to the tested technique.

    Time-use information is preferably obtained from diaries, as this method is considered more reliable than information from questionnaires. The diary-technique seems to be unique in catching the rhythm of every day life and thereby the structuring of work and leisure during a well......-questions are asked about the time spent on paid work and unpaid/household work. The advantage of the latter technique is that it can easily be integrated into surveys. Thus the American National Survey of Families and Households (NSFH) already contains two waves, and a new wave for 2001-2002, which allows...

  17. Analysis of the abundance of abandoned tanks in Hambantota District, Sri Lanka using GIS techniques

    Full Text Available Around two thirds of the area in Sri Lanka is covered by the dry zone, which receives less than 1750 mm average annual rainfall, but not equally distributed over the land. Due to rainfall variations, dry zone of Sri Lanka faced periodic drought conditions in the past. On the basis of surface water availability, Hambantota District appears to be a highly affected area. Tanks have been constructed in order to harvest rainwater to overcome this problem. But, there are many abandoned tanks in Hambantota, which decrease the effectiveness and efficiency of water harvesting. In order to minimize the number of abandoned tanks, an analysis is carried out to find the cause for the abundance of abandoned tanks in the area. Integrating GIS techniques with the relevant data such as rainfall, topographic contours, spot heights, land use, temperature, geology, etc. gives an accurate and updated database, which helps to analyze the reason for the abundance of the abandoned tanks in the area, and hence facilitate the increase of efficiency and effectiveness of rainwater harvesting through a proper water management system.

    Many studies on technology adoption demonstrate that uncertainty leads to a postponement of investments by integrating a wait option in the economic analysis. The aim of this study however is to demonstrate how the investment in new technologies can be stimulated by integrating an option to abandon.

  19. Is sex advantageous in adverse environments? A test of the abandon-ship hypothesis.

    Understanding the evolution and maintenance of sexual reproduction remains a long-standing challenge in evolutionary biology. Stress often induces sexual reproduction in facultatively sexual species (those species capable of both sexual and asexual reproduction). The abandon-ship hypothesis predicts higher allocation to sex under stress to allow low-fitness individuals to recombine their genotype, potentially increasing offspring fitness. However, effective tests of the abandon-ship hypothesis, particularly in multicellular organisms, are lacking. Here we test the abandon-ship hypothesis, using cyanogenic and acyanogenic defense phenotypes of the short-lived perennial herb Trifolium repens. Cyanogenesis provides an effective defense against herbivores and is under relatively simple genetic control (plants dominant for cyanogenesis at two alleles express the defended phenotype). Thus, maladapted individuals can acquire adaptive defense alleles for their offspring in a single episode of sexual reproduction. Plants were grown under high- and low-herbivory treatments (plants were exposed to herbivorous snails) and a control treatment (no herbivory). Herbivores reduced growth and fitness in all treated plants, but herbivory induced higher sexual allocation only in maladapted (acyanogenic) individuals. Overall, our results support the abandon-ship hypothesis.
