Sample records for female perspective long-term

  1. Microfinance and rural development: a long-term perspective

    Moll, H.A.J.

    2006-01-01

    The long-term perspective on microfinance starts with a discussion of three central issues: first, views and policies, with two opposing views: "credit for target group" and "pushing the financial frontier"; second, the performance of microfinance institutions measured via two objectives: outreach

  3. Long-term potentiation and long-term depression: a clinical perspective

    Timothy V.P. Bliss

    2011-01-01

    Full Text Available Long-term potentiation and long-term depression are enduring changes in synaptic strength, induced by specific patterns of synaptic activity, that have received much attention as cellular models of information storage in the central nervous system. Work in a number of brain regions, from the spinal cord to the cerebral cortex, and in many animal species, ranging from invertebrates to humans, has demonstrated a reliable capacity for chemical synapses to undergo lasting changes in efficacy in response to a variety of induction protocols. In addition to their physiological relevance, long-term potentiation and depression may have important clinical applications. A growing insight into the molecular mechanisms underlying these processes, and technological advances in non-invasive manipulation of brain activity, now puts us at the threshold of harnessing long-term potentiation and depression and other forms of synaptic, cellular and circuit plasticity to manipulate synaptic strength in the human nervous system. Drugs may be used to erase or treat pathological synaptic states and non-invasive stimulation devices may be used to artificially induce synaptic plasticity to ameliorate conditions arising from disrupted synaptic drive. These approaches hold promise for the treatment of a variety of neurological conditions, including neuropathic pain, epilepsy, depression, amblyopia, tinnitus and stroke.

  4. Space ventures and society long-term perspectives

    Brown, W. M.

    1985-01-01

    A futuristic evaluation of mankind's potential long term future in space is presented. Progress in space will not be inhibited by shortages of the Earth's physical resources, since long term economic growth will be focused on ways to constrain industrial productivity by changing social values, management styles, or government competence. Future technological progress is likely to accelerate with an emphasis on international cooperation, making possible such large joint projects as lunar colonies or space stations on Mars. The long term future in space looks exceedingly bright even in relatively pessimistic scenarios. The principal driving forces will be technological progress, commercial and public-oriented satellites, space industrialization, space travel, and eventually space colonization.

  5. Long-term leptin fluctuations in female donkeys.

    Čebulj-Kadunc, N; Škibin, A; Kosec, M

    2015-11-01

    The interest in donkeys is growing due to their integration in the systems of ecological farming, among other reasons. Due to limited reports on leptin concentrations in donkeys, the aim of the present study was to examine age-dependent and seasonal changes in the circulating leptin concentration in female donkeys (jennies) and thus contribute to knowledge about the physiological characteristics of this species. Prospective longitudinal study. The study was performed over a year (September 2008 to September 2009) on 20 yearling and young adult (pregnant, lactating or barren) jennies aged 1-5 years at the onset of the study; the animals were kept on pasture from May to September and stabled for the rest of the year. Blood samples were taken monthly and analysed for serum leptin concentrations by a commercial radioimmunoassay kit. Circulating leptin concentrations in studied jennies were lower than those reported for donkeys and horses. Despite the tendency for lower values in yearling vs. young adult jennies, the age range of the examined animals was insufficient to confirm any age-related leptin variations. Significant seasonal leptin fluctuations with peak levels in late spring and the lowest levels in autumn months, correlated with photoperiod, were detected in yearling, barren as well as pregnant jennies. Therefore, it was impossible to identify any effects of gestation or lactation on leptin concentrations of jennies. The results of this study cannot be used as evidence of a causal relationship between the photoperiod and seasonal circulating leptin fluctuations in donkeys, but could reflect changes induced by various external or internal factors enabling adaptations of grazing animals in variable submediterranean environments. © 2014 EVJ Ltd.

  6. Long-term wave measurements in a climate change perspective.

    Pomaro, Angela; Bertotti, Luciana; Cavaleri, Luigi; Lionello, Piero; Portilla-Yandun, Jesus

    2017-04-01

    At present multi-decadal time series of wave data needed for climate studies are generally provided by long term model simulations (hindcasts) covering the area of interest. Examples, among many, at different scales are wave hindcasts adopting the wind fields of the ERA-Interim reanalysis of the European Centre for Medium-Range Weather Forecasts (ECMWF, Reading, U.K.) at the global level and by regional re-analysis as for the Mediterranean Sea (Lionello and Sanna, 2006). Valuable as they are, these estimates are necessarily affected by the approximations involved, the more so because of the problems encountered within modelling processes in small basins using coarse resolution wind fields (Cavaleri and Bertotti, 2004). On the contrary, multi-decadal observed time series are rare. They have the evident advantage of somehow representing the real evolution of the waves, without the shortcomings associated with the limitation of models in reproducing the actual processes and the real variability within the wave fields. Obviously, observed wave time series are not exempt of problems. They represent a very local information, hence their use to describe the wave evolution at large scale is sometimes arguable and, in general, it needs the support of model simulations assessing to which extent the local value is representative of a large scale evolution. Local effects may prevent the identification of trends that are indeed present at large scale. Moreover, a regular maintenance, accurate monitoring and metadata information are crucial issues when considering the reliability of a time series for climate applications. Of course, where available, especially if for several decades, measured data are of great value for a number of reasons and can be valuable clues to delve further into the physics of the processes of interest, especially if considering that waves, as an integrated product of the local climate, if available in an area sensitive to even limited changes of the

  7. HIV-related politics in long-term perspective.

    Friedman, S R

    1998-06-01

    Some long-term, large-scale socio-economic changes may affect the politics of HIV and other emerging viruses such as hepatitis C. It is useful to ask why the potential peace dividend of the early 1990s failed to provide adequate resources for HIV-related social and medical service delivery in developed or developing nations. This failure can be understood by looking at long-term global economic trends and the pressures they put on governments and corporations. They have produced a period in which fundamental issues of political and economic structure are at stake and, often, the response is a divide-and-rule politics to promote stability. National politics differ in terms of the extent to which such a 'politics of scapegoating' is institutionalized and in terms of which groups are scapegoated. Groups such as drug injectors, gay and bisexual men and sex traders are particularly likely to be targeted both by the scapegoaters and by HIV. Given this framework, how should public health professionals and activists engaged in HIV-related issues respond? Under what circumstances should we orient efforts upwards towards corporate, political or bureaucratic leaders? Under what circumstances, and how, should we orient towards popular forces? Relatedly, we need to consider an issue we often ignore: What do we have to offer potential allies? That is, in terms of their goals, philosophies and needs, why should they ally with us?

  8. Who owns the long term? Perspectives from global business leaders.

    Lévy, Maurice; Eskew, Mike; Bernotat, Wulf H; Barner, Marianne

    2007-01-01

    Day-to-day management is challenging enough for CEOs. How do they manage for the long term as well? We posed that question to four top executives of global companies. According to Maurice Levy, chairman and CEO of Publicis Groupe, building the future is really about building the present and keeping close to the front line--those who deal with your customers and markets. He also attributes his company's success in large part to knowing when to take action: In a market where clients' needs steer your long-term future, timing is everything. UPS Chairman and CEO Mike Eskew emphasizes staying true to your vision and values over the long run, despite meeting obstacles along the way. It took more than 20 years, and many lessons learned, to produce consistent profits in what is today the company's fastest-growing and most profitable business: international small packages. Wulf H. Bernotat, CEO of E.ON, examines the challenges facing business leaders and politicians as they try to balance energy needs against potential environmental damage. He calls for educating people about consumption and waste, and he maintains that a diverse and reliable mix of energy sources is the only way to ensure a secure supply while protecting our environment. Finally, Marianne Barner, the director of corporate communications and ombudsman for children's issues at IKEA, discusses how the company is taking steps to improve the environment and be otherwise socially responsible. For example, it's partnering with NGOs to address child labor issues and, on its own, is working to help mitigate climate change. IKEA's goals include using renewable sources for 100% of its energy needs and cutting its overall energy consumption by 25%.

  9. Few long-term consequences after prolonged maternal separation in female Wistar rats.

    Stina Lundberg

    Full Text Available Environmental factors during the early-life period are known to have long-term consequences for the adult phenotype. An intimate interplay between genes and environment shape the individual and may affect vulnerability for psychopathology in a sex-dependent manner. A rodent maternal separation model was here used to study the long-term effects of different early-life rearing conditions on adult behavior, HPA axis activity and long-term voluntary alcohol intake in female rats. Litters were subjected to 15 min (MS15 or 360 min (MS360 of daily maternal separation during postnatal day 1-21. In adulthood, the behavioral profiles were investigated using the multivariate concentric square field™ (MCSF test or examined for HPA axis reactivity by cat-odor exposure with subsequent characterization of voluntary alcohol intake and associated changes in HPA axis activity. Adult female MS360 offspring showed mostly no, or only minor, effects on behavior, HPA axis reactivity and long-term alcohol intake relative to MS15. Instead, more pronounced effects were found dependent on changes in the natural hormonal cycle or by the choice of animal supplier. However, changes were revealed in corticosterone load after long-term alcohol access, as females subjected to MS360 had higher concentrations of fecal corticosterone. The present findings are in line with and expand on previous studies on the long-term effects of maternal separation in female rats with regard to behavior, HPA axis activity and voluntary alcohol intake. It can also be a window into further studies detailing how early-life experiences interact with other risk and protective factors to impact the adult phenotype and how possible sex differences play a role.

  10. Hydrogen in a global long-term perspective

    Quakernaat, J.

    1994-01-01

    For many countries, the hydrogen economy offers an operational objective for their long-term energy structure. At the end of the next century, the world will depend on the predominate use of carbon-free and carbon-neutral sources of energy, such as flow energy, energy from modern biomass, and safe nuclear energy. The direct and indirect costs involved in the use of traditional energy supplies will increase sharply in the process of time, so that the economic feasibility of a less intensive use of energy and the introduction of alternative energy supply systems will no longer be insurmountable problems. The supply and demand structures of energy will be optimally blended by the use of hydrogen and electricity, an almost ideal combination of secondary energy carriers. With these carriers, practically every centralized or decentralized, environmentally sound energy supply can be permanently maintained, both within and outside of industrialized, metropolitan areas. The economic development of developing countries will depend on the predominate use of relatively 'cheap' fossil energy carriers (coal, petroleum and natural gas), as well as on the accompanying energy supplies structures. Yet those countries as well, similar to the wealthy industrial countries, will have to start using the highly capital intensive and very energy efficient energy supply systems and energy consumption technologies. This requires innovative strategies that are aimed at compensating developing countries (temporarily) for their lack of purchasing power and knowledge infrastructure. The costs involved in the hydrogen chain are still too high, and the world energy prices are still too low for such a transfer to take place. The attention, however, will focus on drastic energy saving, decarbonization of fossil fuels, substitution to natural gas, the opening up of flow energy, biomass production, and the development of inherent, safe nuclear energy. 49 refs

  11. HAMMLAB 2000 - Long-Term Perspectives for Use of HAMMLAB

    Kvalem, J.; Berg, Oe.; Foerdestroemmen, N.T.; Groven, A.-K.; Hollnagel, E.; Pettersen, F.; Solie, Aa.S.; Stokke, E.; Sundling, C.-V.

    1996-01-01

    This report discusses the perspectives around future use of the Halden Man-Machine Laboratory, HAMMLAB, to ensure that it continues to be the major tool for the Halden Project's research in man-machine systems and process control. The past few years HAMMLAB has undergone major upgrades to fulfill the requirements from the research programmes, and the present HAMMLAB will, with some modifications, be able to serve the research programme for 1997-99. There is, however, a need to look beyond the coming three-year period in order to make sure that HAMMLAB also in the next decades will serve as a global centre of excellence for human-technology interaction studies. Hence, an attempt is made to identify future research needs regarding process control for the beginning of the 21st century. Different aspects of process control are discussed, and their needs for experimental evaluation are pointed out. Based upon the expressed needs for an experimental facility, a discussion is raised around what this means for HAMMLAB, and which specific requirements this imposes on the laboratory. The conclusion is that there is a need for a new, larger and multi-purpose HAMMLAB facility to meet the identified requirements to a complete experimental facility. In the last part of the report a development plan for a new HAMMLAB facility is proposed, and a brief discussion is raised regarding utilisation of resources and the financing aspect. (author)

  12. Analysis on long-term perspectives of sustainable nuclear energy towards global warming protection

    Yamazawa, M.; Ichimura, E.; Shibata, Y.; Kobayashi, K.; Wajima, T.

    1998-01-01

    Study of long-term perspectives of the nuclear power generation was made from the point of views of both CO 2 emission constraints and sustainability of nuclear energy. To this end, STREAM (Semi-empirical TRiple E Analysis Model) program, as a social model, has been developed by Tokyo Electric Power Co. and Hitachi, Ltd. Using this program, long-term world demands of primary and nuclear energy were deduced, in view of the protection against the global warming due to the CO 2 gas accumulation. The inevitable conclusion has been drawn that nuclear energy plays an indispensable role in the reduction of green house effect. Evaluations were then made on conditions that the nuclear power system would be the long-term major sustainable energy source. (author)

  13. Long term verbal memory recall deficits in fragile X premutation females.

    Shelton, Annie L; Cornish, Kim; Fielding, Joanne

    2017-10-01

    Carriers of a FMR1 premutation allele (between 55 and 199 CGG repeats) are at risk of developing a wide range of medical, psychiatric and cognitive disorders, including executive dysfunction. These cognitive deficits are often less severe for female premutation carriers compared to male premutation carriers, albeit similar in nature. However, it remains unclear whether female premutation carriers who exhibit executive dysfunction also report verbal learning and memory deficits like those of their male counterparts. Here we employed the CVLT to assess verbal learning and memory function in 19 female premutation carriers, contrasting performance with 19 age- and IQ-matched controls. Group comparisons revealed similar performance during the learning and short delay recall phases of the CVLT. However, after a long delay period, female premutation carriers remembered fewer words for both free and cued recall trials, but not during recognition trials. These findings are consistent with reports for male premutation carriers, and suggest that aspects of long term memory may be adversely affect in a subgroup of premutation carriers with signs of executive dysfunction.

  14. Long-term moderate treadmill exercise promotes stress-coping strategies in male and female rats.

    Lalanza, Jaume F; Sanchez-Roige, Sandra; Cigarroa, Igor; Gagliano, Humberto; Fuentes, Silvia; Armario, Antonio; Capdevila, Lluís; Escorihuela, Rosa M

    Recent evidence has revealed the impact of exercise in alleviating anxiety and mood disorders; however, the exercise protocol that exerts such benefit is far from known. The current study was aimed to assess the effects of long-term moderate exercise on behavioural coping strategies (active vs. passive) and Hypothalamic-Pituitary-Adrenal response in rats. Sprague-Dawley male and female rats were exposed to 32-weeks of treadmill exercise and then tested for two-way active avoidance learning (shuttle-box). Two groups were used as controls: a non-handled sedentary group, receiving no manipulation, and a control group exposed to a stationary treadmill. Female rats displayed shorter escape responses and higher number of avoidance responses, reaching criterion for performance earlier than male rats. In both sexes, exercise shortened escape latencies, increased the total number of avoidances and diminished the number of trials needed to reach criterion for performance. Those effects were greater during acquisition in female rats, but remained over the shuttle-box sessions in treadmill trained male rats. In females, exercise did not change ACTH and corticosterone levels after shuttle-box acquisition. Collectively, treadmill exercise improved active coping strategies in a sex-dependent manner. In a broader context, moderate exercise could serve as a therapeutic intervention for anxiety and mood disorders.

  15. Immediate and Long-Term Mental Health Outcomes in Adolescent Female Rape Survivors.

    Oshodi, Yewande; Macharia, Muiruri; Lachman, Anusha; Seedat, Soraya

    2016-12-01

    Rape is considered a stressful trauma and often has long-lasting health consequences. Compared with adult females, limited data exist on the psychological impact of rape in adolescents. The aim of this study was to assess the prevalence and associated factors of emotional distress in a cohort of adolescent rape survivors in Cape Town. Participants in this prospective longitudinal study were 31 adolescent female rape survivors recruited from a rape clinic in Cape Town and assessed within 2 weeks of the assault. Assessment measures included a sociodemographic questionnaire and initial screening with the Child and Adolescent Trauma Survey (CATS), the patient-rated Children's Depression Inventory (CDI), and the Multidimensional Anxiety Scale for Children (MASC). The CATS, CDI, and MASC were repeated at 1, 3, 6, 9, and 12 months post enrollment. Psychiatric diagnoses were made with the clinician-administered Mini International Neuropsychiatric Interview-Child and Adolescent version (MINI-Kid). At baseline, on the MINI-Kid, a definitive diagnosis of major depressive episode was endorsed in 22.6% of the participants. Stress-related disorders were found in 12.9%, whereas 16.1% had anxiety disorders. There was no diminution of symptoms on self-reported psychopathology measures at follow-up assessment over the five follow-up time points, suggesting persistent psychopathology over a 1-year period despite repeated clinical assessments and supportive counseling. Symptoms of anxiety, depression, and posttraumatic stress disorder in this sample of adolescent female rape survivors were high at enrollment and found to be persistent, underlining the need for long-term support, screening, and evidence-based follow-up care.

  16. Perspectives of survivors of traumatic brain injury and their caregivers on long-term social integration.

    Lefebvre, Hélène; Cloutier, Geneviève; Josée Levert, Marie

    2008-07-01

    Traumatic brain injury (TBI) has damaging impacts on victims and family members' lives and their long-term social integration constitutes a major challenge. The objective of the study was to document the repercussions of TBI on victims' long-term social integration (10 years post-trauma) and the contribution made by the services received from the point of view of TBI victims and family caregivers. This article examines the determinants of long-term social integration as well as the impact of TBI on family caregivers. A qualitative design was used (semi-directed interviews). The sample consisted of 22 individuals who had sustained a moderate or severe TBI and 21 family caregivers. The results show that TBI is an experience that continues to present difficulties, even 10 years after the accident, and that different barriers contribute to this difficulty: not going back to work, depressive episodes, problems in relationships and sequellae. Family caregivers must help TBI victims confront the barriers in their path. This study adopts a longitudinal perspective to help professionals determine how to intervene with TBI victims and their families. It validates the importance of having clients and family caregivers describe their reality.

  17. Long-term effects of prenatal x-ray of human females. II. Growth and development.

    Meyer, M B; Tonascia, J

    1981-09-01

    Experimental studies and studies of survivors of in-utero exposure to atomic bomb blasts have shown significant stunting of growth and mental retardation following these exposures. Central nervous system damage following very low doses of x-ray at around the time of birth has also been observed in experimental animals. This long term follow-up studies of 1458 human females exposed in utero to diagnostic x-rays and of 1458 matched unexposed controls studied in Baltimore, Maryland, included measurements of height, weight and school achievement. Women who had been exposed to x-rays in utero were significantly shorter in their mid-twenties than were their matched, unexposed controls, even after adjustment for other social and economic factors. However, additional follow-up revealed that mothers of exposed women were also shorter than the control mothers. Short stature appeared to be a selective factor for x-ray during pregnancy (mostly pelvimetry, 1947-1952). Mothers' and daughters' heights were similarly correctly among exposed and control mother-daughter pairs, suggesting that the height differences between exposed daughters and their controls were due to these selective factor rather than to any direct effect of radiation on growth. Exposed women reported poorer school achievement than control women. However, except for a higher proportion of exposed women leaving school because of pregnancy, these measurements were no longer significantly different when rates were simultaneously adjusted for socioeconomic differences between exposed and control women.

  18. Functional Connectivity of the Precuneus in Female University Students with Long-Term Musical Training.

    Tanaka, Shoji; Kirino, Eiji

    2016-01-01

    Conceiving concrete mental imagery is critical for skillful musical expression and performance. The precuneus, a core component of the default mode network (DMN), is a hub of mental image processing that participates in functions such as episodic memory retrieval and imagining future events. The precuneus connects with many brain regions in the frontal, parietal, temporal, and occipital cortices. The aim of this study was to examine the effects of long-term musical training on the resting-state functional connectivity of the precuneus. Our hypothesis was that the functional connectivity of the precuneus is altered in musicians. We analyzed the functional connectivity of the precuneus using resting-state functional magnetic resonance imaging (fMRI) data recorded in female university students majoring in music and nonmusic disciplines. The results show that the music students had higher functional connectivity of the precuneus with opercular/insular regions, which are associated with interoceptive and emotional processing; Heschl's gyrus (HG) and the planum temporale (PT), which process complex tonal information; and the lateral occipital cortex (LOC), which processes visual information. Connectivity of the precuneus within the DMN did not differ between the two groups. Our finding suggests that functional connections between the precuneus and the regions outside of the DMN play an important role in musical performance. We propose that a neural network linking the precuneus with these regions contributes to translate mental imagery into information relevant to musical performance.

    , responses to this treatment in females and long-term effects on outcome are not known. Initial experiments used in vitro organ culture of cerebral arteries, confirming ERK1/2 activation and increased ETB receptor-mediated vasoconstriction in female cerebral arteries. Transient middle cerebral artery......-mediated contraction was studied with myograph and protein expression with immunohistochemistry. In vitro organ culture and tMCAO resulted in vascular ETB receptor upregulation and activation of ERK1/2 that was prevented by U0126. Although no effect on infarct size, U0126 improved the long-term neurologic function...

  1. Interpersonal and group processes in long-term spaceflight crews: perspectives from social and organizational psychology.

    Dion, Kenneth L

    2004-07-01

    The issues of interpersonal and group processes in long-term spacecrews from the perspectives of social and organizational psychology are considered here. A contrast between the Amundsen vs. Scott expeditions to the South Pole 90 yrs. ago highlights the importance of personnel selection and attention to interpersonal and group dynamics in expeditions to extreme and dangerous environments, such as long-term spaceflights today. Under the rubric of personnel selection, some further psychological "select-in" and "select-out" criteria are suggested, among them implicit measures of human motivation, intergroup attitudes ("implicit" and "explicit" measures of prejudice, social dominance orientation, and right-wing authoritarianism), attachment styles, and dispositional hardiness. The situational interview and the idea of "selection for teams," drawn from current advances in organizational psychology, are recommended for selecting members for future spacecrews. Under the rubrics of interpersonal and group processes, the social relations model is introduced as a technique for modeling and understanding interdependence among spacecrew members and partialling out variance in behavioral and perceptual data into actor/perceiver, partner/target, and relationship components. Group cohesion as a multidimensional construct is introduced, along with a consideration of the groupthink phenomenon and its controversial link to cohesion. Group composition issues are raised with examples concerning cultural heterogeneity and gender composition. Cultural value dimensions, especially power distance and individual-collectivism, should be taken into account at both societal and psychological levels in long-term space missions. Finally, intergroup processes and language issues in crews are addressed. The recategorization induction from the common ingroup identity model is recommended as a possible intervention for overcoming and inhibiting intergroup biases within spacecrews and between space

  2. Lock-in and change: Distributed generation in Denmark in a long-term perspective

    Vleuten, Erik van der; Raven, Rob

    2006-01-01

    There is a renewed attention for distributed generation (DG) in European electricity sectors, but implementing DG is often problematic. This article studies the current relative success of DG in Denmark. We take into account not only recent drivers of change such as energy policy and green activism, but also long-term stability and change in the electricity supply sector. In particular we analyse the lock-in on centralized electricity supply, that still frustrates DG development elsewhere. We discuss three successive national electricity regimes, analysing regime lock-in and change in terms of technologies, actors, institutions and the position of DG. Our analysis shows that Danish energy policy as well as innovative activity by key actors indeed were crucial to the recent DG revival in Denmark. On the other hand, our long-term perspective shows that Danish energy policy and actor strategies were tuned to specifically Danish opportunities and barriers created during earlier regimes. These include experience with wind turbines and CHP as well as urban municipal and rural cooperative involvement. Copying the Danish energy policy model to other countries, regardless of national specific opportunities and barriers, will therefore not guarantee a similar outcome

  3. Long-term perspectives of the worldwide use of nuclear power

    Jaek, W.

    1981-01-01

    The world energy scenarios developed by WEC and IIASA, which contain analyses and estimates on the long-term development perspectives of regional development areas, show that the worldwide energy requirement can no longer be met without the large-scale expansion of nuclear power. This implies an expansion on nuclear power in the next forty or fifty years to more than the 38 countries at present known to use or wanting to use nuclear power. With respect to the aspects of supply and non-proliferation, the question of the geographic distribution of future nuclear power plants is becoming more and more important. If the more global statements in the different world energy scenarios can be translated into information about the potential use of nuclear power in specific countries in the fifty years, this will allow a picture of a possible nuclear future to be sketched, on the basis of which considerations of non-proliferation and nuclear transfer can be put on a firm basis. This is not meant to be another set of long-term forecasts of nuclear power, but a concrete implementation of world energy scenarios and the consequences with respect to non-proliferation and transfer potentially arising from them.

  4. Nonsurgical Outpatient Therapies for the Management of Female Stress Urinary Incontinence: Long-Term Effectiveness and Durability

    G. Willy Davila

    2011-01-01

    Results. Thirty-two clinical trial reports were included. Prospective long-term studies of pelvic floor rehabilitation were limited but indicated significant improvements with treatment adherence for at least 12 months. Poor initial tolerability with duloxetine resulted in substantial discontinuation. Most patients receiving transurethral radiofrequency collagen denaturation or urethral bulking agents reported significant long-term improvements, generally good tolerability, and safety. Conclusions. Conservative therapy is an appropriate initial approach for female SUI, but if therapy fails, radiofrequency collagen denaturation or bulking agents may be an attractive intermediate management step or alternative to surgery.

  5. Bullying in Senior Living Facilities: Perspectives of Long-Term Care Staff.

    Andresen, Felicia J; Buchanan, Jeffrey A

    2017-07-01

    Resident-to-resident bullying has attracted attention in the media, but little empirical literature exists related to the topic of senior bullying. The aim of the current study was to better understand resident-to-resident bullying from the perspective of staff who work with older adults. Forty-five long-term care staff members were interviewed regarding their observations of bullying. Results indicate that most staff members have observed bullying. Verbal bullying was the most observed type of bullying, but social bullying was also prevalent. Victims and perpetrators were reported to commonly have cognitive and physical disabilities. More than one half of participants had not received formal training and only 21% reported their facility had a formal policy to address bullying. The implications of these results support the need for detailed policies and training programs for staff to effectively intervene when bullying occurs.

  6. Walrus history around the North Water: Human-animal relations in a long-term perspective.

    Gotfredsen, Anne Birgitte; Appelt, Martin; Hastrup, Kirsten

    2018-04-01

    This article highlights the relationship between walruses and humans in and around the North Water polynya in a long-term perspective. The present study draws on a combination of biological, archaeological, archaeo-zoological, historical, and ethnographic sources covering the period from the 8th century AD to the late 20th century. The study demonstrates that the walrus was an important resource of meat, blubber, and other products throughout all the studied periods, if always supplemented by other kinds of game. It is suggested that walrus distribution and behaviour, as well as hunting strategies and technologies historically constituted a powerful component not only in forming human action and social life in the region but also in serving as an imaginative resource. It is further argued that the walrus and the walrus hunt still play a significant role in the present community living on the edge of the North Water, even if the hunt is increasingly circumscribed due to changing ice conditions.

    2015-05-01

    To assess the prospective associations between self-reported physical capacity and risk of long-term sickness absence among female health care workers. Female health care workers answered a questionnaire about physical capacity and were followed in a national register of sickness absence lasting for two or more consecutive weeks during 1-year follow-up. Using Cox regression hazard ratio analyses adjusted for age, smoking, body mass index, physical workload, job seniority, psychosocial work conditions, and previous sickness absence, we modeled risk estimates for sickness absence from low and medium physical capacity. Low and medium aerobic fitness, low muscle strength, low flexibility, and low overall physical capacity significantly increased the risk for sickness absence with 20% to 34% compared with health care workers with high capacity. Low physical capacity increases the risk of long-term sickness absence among female health care workers.

  9. Rubble Women: The Long-Term Effects of Postwar Reconstruction on Female Labor Market Outcomes

    Akbulut-Yuksel, Mevlude; Khamis, Melanie; Yuksel, Mutlu

    2011-01-01

    During World War II, more than one-half million tons of bombs were dropped in aerial raids on German cities, destroying about forty percent of the total housing stock nationwide. With a large fraction of the male population gone, the reconstruction process had mainly fallen on women in postwar Germany. This paper provides causal evidence on long-term legacies of postwar reconstruction and mandatory employment on women's labor market outcomes. We combine a unique dataset on city-level destruct...

  10. Functional Connectivity of the Precuneus in Female University Students with Long-Term Musical Training

    Tanaka, Shoji; Kirino, Eiji

    2016-01-01

    Conceiving concrete mental imagery is critical for skillful musical expression and performance. The precuneus, a core component of the default mode network (DMN), is a hub of mental image processing that participates in functions such as episodic memory retrieval and imagining future events. The precuneus connects with many brain regions in the frontal, parietal, temporal, and occipital cortices. The aim of this study was to examine the effects of long-term musical training on the resting-sta...

  11. Long Term Fuel Sustainable Fission Energy Perspective Relevant for Combating Climate Change

    Knapp, V.; Matijevic, M.; Pevec, D.; Crnobrnja, B.; Lale, D.

    2016-01-01

    In recent research we outlined climate relevant and immediately available proven light water nuclear strategy with a potential to contribute essentially and timely to reduction of carbon dioxide emission to the year 2065. We consider in this paper what is the perspective of fission energy after that year should its contribution be needed. Singling out two technologies with long term perspective which need no or small amounts of uranium, fast breeders and molten salt thorium reactors, we consider their main technical and safety characteristics. In both of these technologies it is essential to have starter nuclides as neither U238 nor Th232 are fissile. We investigated whether plutonium from spent fuel of light water reactors generated to the year 2065 would be present in quantities sufficient to continue operation on the same or similar level in both technologies. However in operational safety, proliferation risks, waste production, in our judgement we must give preference to thorium technology, if it would be ready in second half of the century.(author).

    2014-01-01

    Full Text Available Introduction: Limbic encephalitis (LE is characterized by rapidly progressive short-term memory loss, psychiatric symptoms and seizures. We describe the clinical spectrum, underlying etiology and long-term follow-up of patients with LE from India. Materials and Methods: This prospective study included patients during the period of January 2009 and December 2011 with the clinical features consistent with LE with one or more of the following: (1 Magnetic resonance imaging (MRI evidence of temporal lobe involvement; (2 cerebrospinal fluid inflammatory abnormalities, or (3 detection of antineuronal antibodies. Patients with metastasis, infection, metabolic and nutritional deficits, stroke, were excluded. Results: There were 16 patients (9 females, mean age of presentation was 36.6 years (range 15-69 years. The mean duration of symptoms before presentation was 11 months (range 5 days-2 years. The most common symptom at presentation was short-term memory impairment in 7 patients followed by seizures in 5 and behavioral changes in three. Nine patients had seizures, 11 had change in behavior, language involvement in eight, cerebellar features in 3 and autonomic dysfunction in two. Four patients had associated malignancy, 3 of four presented with neurological symptoms and on investigations found to be have malignancy. Antineuronal antibody testing was done in 6 of 12 non paraneoplastic and two paraneoplastic patients, one positive for N-methyl-D-aspartate and one for anti-Hu antibody. MRI brain showed typical fluid attenuated inversion recovery or T2 bilateral temporal lobe hyperintensities in 50% of patients. At a mean follow-up of 21 months (3-36 months, 10 patients improved, 4 patients remained same and two patients expired. Conclusion: Early recognition of LE is important based upon clinical, MRI data in the absence of antineuronal surface antibody screen in developing nations. Early institution of immunotherapy will help in improvement in outcome of

  13. Workplace Violence and Safety Issues in Long-Term Medical Care Facilities: Nurses' Perspectives.

    Fasanya, Bankole K; Dada, Emmanuel A

    2016-06-01

    Workplace violence (WPV) is becoming an issue that needs immediate attention in the United States, especially during this period as more states are adopting the "stand your ground laws to promote worker protection." This study was conducted to investigate how WPV has contributed to an unsafe environment for nurses and nursing assistants who work in long-term medical care facilities. A structure questionnaire was used to collect data for the study. Three facilities were sampled and 80 nurses and certified nursing assistants participated in the study. Ninety-two percent (n = 74) were female and 8% (n = 6) were male. Approximately 62% were black or African American, approximately 33% were Caucasians, and only 2% were from other ethnicities. We found that 65% of the participants had experienced WPV while 41% believed that management shows little or no concern for their safety. Approximately 23% of respondents believed that reporting supervisor's WPV act is an unsafe action. In addition, 22% of those who reported that they have experienced WPV believed that the work environment is not safe to perform their duties. This significant difference in perception of workplace safety between those who had experienced WPV and those who had not was significant (t = 3.95, df = 158, p < 0.0001). WPV is an epidemic problem that affects all health-care professionals. The findings of this study could help long-term medical care facilities' management identify the areas to focus on mitigating, controlling, and/or eliminating incidents of WPV.

  14. Long-term contracts vs. short-term trade of natural gas - a European perspective

    Neuhoff, Karsten; Hirschhausen, Christian von

    2005-01-01

    This paper analyses the economics of long-term gas contracts under changing institutional conditions, mainly gas sector liberalisation. The paper is motivated by the increasingly tense debate in continental Europe, UK and the US on the security of long-term gas supply. We discuss the main issues regarding long-term contracts, i.e. the changing role of the flexibility clause, the effect of abandoning the destination clause, and the strategic behaviour of producers between long-term sales and spot-sales. The literature suggests consumers and producers benefit from risk hedging through long-term contracts. Furthermore long-term contracts may reduce exercise of market power. Our analysis adds an additional benefit if the long-run demand elasticity is significantly lower than the short-run elasticity, both strategic producers and consumers benefit from lower prices and larger market volume. Some policy implications of the findings are also discussed. (Author)

  15. Neonatal overfeeding disrupts pituitary ghrelin signalling in female rats long-term; Implications for the stress response.

    Sominsky, Luba; Ziko, Ilvana; Spencer, Sarah J

    2017-01-01

    The hypothalamic-pituitary-adrenal (HPA) axis responses to psychological stress are exacerbated in adult female but not male rats made obese due to overfeeding in early life. Ghrelin, traditionally known for its role in energy homeostasis, has been recently recognised for its role in coordinating the HPA responses to stress, particularly by acting directly at the anterior pituitary where the growth hormone secretagogue receptor (GHSR), the receptor for acyl ghrelin, is abundantly expressed. We therefore hypothesised that neonatal overfeeding in female rats would compromise pituitary responsiveness to ghrelin, contributing to a hyperactive central stress responsiveness. Unlike in males where hypothalamic ghrelin signalling is compromised by neonatal overfeeding, there was no effect of early life diet on circulating ghrelin or hypothalamic ghrelin signalling in females, indicating hypothalamic feeding and metabolic ghrelin circuitry remains intact. However, neonatal overfeeding did lead to long-term alterations in the pituitary ghrelin system. The neonatally overfed females had increased neonatal and reduced adult expression of GHSR and ghrelin-O-acyl transferase (GOAT) in the pituitary as well as reduced pituitary responsiveness to exogenous acyl ghrelin-induced adrenocorticotropic hormone (ACTH) release in vitro. These data suggest that neonatal overfeeding dysregulates pituitary ghrelin signalling long-term in females, potentially accounting for the hyper-responsive HPA axis in these animals. These findings have implications for how females may respond to stress throughout life, suggesting the way ghrelin modifies the stress response at the level of the pituitary may be less efficient in the neonatally overfed.

  16. Perspective of long term demand and supply of energy and general inspection of energy policy

    1983-01-01

    Since the oil crisis, Japanese energy policy was promoted to get rid of the excess dependence on petroleum and to attain energy security, but energy situation largely changed during the past ten years, and it has become necessary to make general inspection on the long term demand and supply of energy and the energy policy. After the second oil crisis, the worldwide demand of petroleum decreased drastically due to the rapid price rise, and the base price of crude oil was lowered for the first time. It is necessary to positively endeavor to reduce energy cost with new idea. The points of the general inspection are the correspondence of the energy policy to the large structural change of energy, the most desirable system for attaining the optimum structure of energy demand and supply and the utilization of market mechanism as far as possible. This report is the results of discussion held eight times since April, 1983. The change of energy situation in Japan and abroad and the perspective, the new problems in energy countermeasures and the trend of response, the preferential and effective promotion of general energy countermeasures and so on are reported. This report shows the fundamental direction of energy countermeasures hereafter, and the concrete and special examination must be made on many remaining problems. (Kako, I.)

  17. Impact of short-term severe accident management actions in a long-term perspective. Final Report

    2000-03-01

    The present systems for severe accident management are focused on mitigating the consequences of special severe accident phenomena and to reach a safe plant state. However, in the development of strategies and procedures for severe accident management, it is also important to consider the long-term perspective of accident management and especially to secure the safe state of the plant. The main reason for this is that certain short-term actions have an impact on the long-term scenario. Both positive and negative effects from short-term actions on the accident management in the long-term perspective have been included in this paper. Short-term actions are accident management measures taken within about 24 hours after the initiating event. The purpose of short-term actions is to reach a stable status of the plant. The main goal in the long-term perspective is to maintain the reactor in a stable state and prevent uncontrolled releases of activity. The purpose of this short Technical Note, deliberately limited in scope, is to draw attention to potential long-term problems, important to utilities and regulatory authorities, arising from the way a severe accident would be managed during the first hours. Its objective is to encourage discussions on the safest - and maybe also most economical - way to manage a severe accident in the long term by not making the situation worse through inappropriate short-term actions, and on the identification of short-term actions likely to make long-term management easier and safer. The Note is intended as a contribution to the knowledge base put at the disposal of Member countries through international collaboration. The scope of the work has been limited to a literature search. Useful further activities have been identified. However, there is no proposal, at this stage, for more detailed work to be undertaken under the auspices of the CSNI. Plant-specific applications would need to be developed by utilities

  18. New long-term plan of nuclear development and perspectives of nuclear fuel cycle policy

    Uchiyama, Yohji

    2005-01-01

    Japan's nuclear fuel cycle policy, recently issued as an interim report of the Council to Formulate the New Long-Term Nuclear Program of the Atomic Energy Commission, is summarized and briefly explained together with the concluding remarks from the sub-committee for discussing technical and economical problems on the spent nuclear fuels with the present state of the Rokkasho reprocessing plant in mind. As for the nuclear fuel treatment, the panel considered four scenarios: (1) total reprocessing (the reprocessing for spent fuel after an appropriate period of storage); (2) partial reprocessing (spent fuel is reprocessed, with direct disposal of any spent fuel in excess of reprocessing capacity); (3) total direct disposal (direct disposal of all spent fuel); and (4) temporary storage (spent fuel is temporarily stored, and in about 2060 a choice will be made about whether to reprocess it or directly dispose of it). These four scenarios were studied from various perspectives, namely: (1) ensuring safety; (2) energy security; (3) environmental compatibility; (4) economic efficiency; (5) nuclear nonproliferation; (6) technical feasibility; (7) social acceptance; (8) securing choices; (9) issues concerning change in policy; and (10) overseas trends. Regarding economic efficiency, the council in particular conducted detailed studies and reassessment of nuclear fuel cycle costs. Scenario 1 (total reprocessing) is about 0.5-0.7 yen/kWh higher than scenario 3 (total direct disposal). However, looking at the situation from the perspectives of energy security, that is the stable supply and moderate use of resources, and environmental compatibility, scenario 1 (total reprocessing) can be evaluated as superior to the other scenarios. And more importantly, if the fast-breeder reactor cycle is commercialized, this superiority increases considerably. (S. Ohno)

  19. Long-term follow-up after urethral injection with polyacrylamide hydrogel for female stress incontinence

    Mouritsen, Lone; Lose, Gunnar; Møller-Bek, Karl

    2014-01-01

    Urethral injection therapy for treatment of stress urinary incontinence has been in use for years, but only a few long-term follow-up studies have been published. Twenty-five women, injected with polyacrylamide hydrogel 8 years earlier, were invited for follow-up. Twenty-four could be contacted; 15...... had had no further treatment, seven had been re-operated with placement of mid-urethral slings, and two had been re-injected with polyacrylamide hydrogel. Eleven women attended for objective examination; all non-attenders were interviewed by telephone. Subjectively, in 44% the stress incontinence...... was cured or much improved, with a positive outcome according to the King's Health Questionnaire. Objectively, all patients had visible polyacrylamide hydrogel deposits on vaginal ultrasonography. No local adverse reactions were seen in the vaginal mucosa. The results of a later mid-urethral sling were...

    Conditional survival is defined as the probability of surviving an additional number of years beyond that already survived. The aim of this study was to compute conditional survival in patients who received a robotically assisted, minimally invasive mitral valve repair procedure (RMVP). Patients who received RMVP with annuloplasty band from May 2000 through April 2011 were included. A 5- and 10-year conditional survival model was computed using a multivariable product-limit method. Non-smoking men (≤65 years) who presented in sinus rhythm had a 96% probability of surviving at least 10 years if they survived their first year following surgery. In contrast, recent female smokers (>65 years) with preoperative atrial fibrillation only had an 11% probability of surviving beyond 10 years if alive after one year post-surgery. In the context of an increasingly managed healthcare environment, conditional survival provides useful information for patients needing to make important treatment decisions, physicians seeking to select patients most likely to benefit long-term following RMVP, and hospital administrators needing to comparatively assess the life-course economic value of high-tech surgical procedures.

    The United States population is rapidly aging, and retaining direct care workers (DCWs) will continue to be a workforce concern for the industry in addressing the demand for long term care services. To date, scant literature exists that addresses the DCW perspective of leadership behaviors and their influence on organizational commitment. To…

  2. A United States perspective on long-term management of areas contaminated with radioactive materials

    Jones, C. R.

    2004-01-01

    The US has far-reaching and extensive experience in the long-term management of areas contaminated with radioactive materials. This experience base includes the Dept. of Energy's continued follow-up with Hiroshima and Nagasaki from the 1940's at the Radiological Effects Research Foundation in Hiroshima (Japan)), the long-term management of the Marshall Islands Programme, the clean-up of the US nuclear weapons complex and the ongoing management of accident sites such as in Palomares (Spain)). This paper discusses the lessons learnt and best practices gained from this far-reaching and extensive experience in the long-term management of areas contaminated with radioactive materials.

  3. Female urethral strictures: successful management with long-term clean intermittent catheterization after urethral dilatation.

    Smith, Ariana L; Ferlise, Victor J; Rovner, Eric S

    2006-07-01

    To report our experience in the diagnosis and treatment of urethral stricture in women. A retrospective review of records and video-urodynamics identified women treated for urethral stricture between 1999 and 2004 at one institution by one surgeon. Urethral stricture was defined as a fixed anatomical narrowing between the bladder neck and distal urethra of or = 30 F. After a period of indwelling catheterization, the women were placed on clean intermittent self-catheterization (CISC) at least once daily, and monitored every 3-6 months. At each follow-up, the urethra was catheterized to exclude recurrence. American Urological Association (AUA) symptom scores were obtained at presentation and at the initial 3 month follow-up. Seven women met the criteria for urethral stricture, and were followed for a mean (range) of 21 (6-34) months. All were initially maintained on daily CISC, and some were gradually reduced to weekly CISC for the duration of follow-up. No patient had a recurrent stricture while on CISC, and none has had a urethral reconstruction to manage their condition. AUA symptom scores improved in all of the women by a mean of 10.7 points. No complications related to catheterization were noted. Urethral stricture is rare in women. Long-term CISC in these women is safe and effective, and can avoid the need for major reconstructive surgery.

  4. Long-term effects of prenatal x-ray of human females: mortality and morbidity

    Meyer, M.B.; Tonascia, J.

    1981-01-01

    Experimental studies and long-term studies of humans exposed to ionizing radiation in utero and after birth show that these exposures increase the risk of cancer in childhood and in later life. A possible life-shortening effect has also been reported. This study followed to their mid-twenties 1458 women exposed in utero to diagnostic x-rays and 1458 matched, unexposed controls in Baltimore, Maryland, and obtained responses from over 100 women in each group. Information about general health and specific diseases was obtained from questionnaires. Deaths were ascertained through family members and death certificates. Mortality rates were slightly higher among exposure. Exposed women reported poor general health significantly more often than controls. Specific diseases occurred similarly in the two groups, although exposed women reported more epilepsy or fits, more ovarian tumors, and more high blood pressure. These strong correlation between weight and high blood pressure and the heavier weights of exposed women seemed to account for this difference. In summary, these matched exposed and control women, followed to their mid-twenties, experienced similar rates of morbidity and mortality. Radiation-induced cancers and life-shortening effects, if any, might not become evident until older ages

  5. Torture and Long-Term Health Effects Among Lebanese Female Political Prisoners.

    Ghaddar, Ali; Elsouri, Ghadier; Abboud, Zeinab

    2016-02-01

    Lebanese prisoners during the Israeli occupation of Lebanon (1981-1999) were subject to regular torture. We examined the association between torture events and post-traumatic stress and cardiovascular diseases (CVDs) among former women political prisoners. We conducted a retrospective survey and performed health check-ups among 108 former women prisoners. Post-traumatic stress disorder (PTSD) was measured through the Clinician-Administered PTSD Scale (CAPS), and CVDs were assessed by physicians' diagnoses. The study was conducted between September 2008 and March 2010. All 67 participants in the study reported having been subjected to a variety of torture events. The prevalence of PTSD was 28.4% and that of CVD was 16.42%, respectively. PTSD and CVD were more likely to occur among women who had had longer imprisonment periods, and PTSD specifically was associated with exposure to torture (beating: OR = 1.49; 95% CI [0.48, 4.27] and threatening by rape: OR = 1.43; 95% CI [0.82, 9.30]). CVD was associated with asphyxia with water (OR = 3.86; 95% CI [0.03, 2.28]). Devoutness decreased the risk of PTSD (OR = 0.24; 95% CI [0.08, 1.41]). Torture had adverse long-term effects on prisoners' physiological and psychological health; devoutness played a significant protective role. This study highlights the importance of documenting torture events and identifying the indicators of associated morbidity among surviving political prisoners for the provision of additional resources to care. © The Author(s) 2014.

  6. Predictors of short- and long-term sickness absence in female post office workers in Poland

    Zuzanna Szubert

    2016-08-01

    Full Text Available Background: The aim of this study was to highlight major predictors of the frequency of sickness absence in a group of workers directly involved in customer service. Material and Methods: The study was carried out on a random sample of 229 women employed as assistants and clerks in post offices. The survey was based on the Subjective Work, Health Status and Life Style Characteristics Questionnaire, and sickness absence data for the years 2004–2006. Results: The negative binominal regression model of sickness absence risk revealed the following significant predictors of short-term absence spells (1–29 days: 1 marital status, sickness absence risk for single women was (rate ratio (RR = 1.56 (95% confidence interval (CI: 1.01–2.39 vs. married women; 2 post offices employing 7 workers had a rate ratio of sickness absence of 1.6 (95% CI: 1.04–2.42; 13–25 workers – RR = 2.03 (95% CI: 1.41–2.93; > 25 workers – RR = 1.82 (95% CI: 1.15–2.88 compared with an average number of 8–12 workers; 3 shift work, RR = 1.57 (95% CI: 1.14–2.14; 4 breaks from work – the risk of absence in the case of any breaks amounted to RR = 1.5 (95% CI: 1.07–2.07 in comparison with the statutory breaks; 5 self-rated health reported as moderate relative to good health, RR = 1.71 (95% CI: 1.26–2.32; and 6 occurrence of respiratory diseases resulted in the risk of RR = 1.51 (95% CI: 1.08–2.08. The Poisson regression model of long-term sickness absence spells (≥ 30 days revealed the following significant predictors: 1 number of clients per shift: 51–100 clients, RR = 3.62 (95% CI: 1.07–22.6 compared with a lower number of clients; 2 self-rated health, assessed as moderate, RR = 1.97 (95% CI: 1.06–3.78 and 3 household chores performed for at least 4 h a day, RR = 0.4 (95% CI: 0.18–0.79. Conclusions: Association between sickness absence and workload as well as work organization indicates directions of corrective actions, which could reduce the

  7. Long-Term Effects of Intermittent Adolescent Alcohol Exposure in Male and Female Rats

    Eva M. Marco

    2017-11-01

    Full Text Available Alcohol is a serious public health concern that has a differential impact on individuals depending upon age and sex. Patterns of alcohol consumption have recently changed: heavy episodic drinking—known as binge-drinking—has become most popular among the youth. Herein, we aimed to investigate the consequences of intermittent adolescent alcohol consumption in male and female animals. Thus, Wistar rats were given free access to ethanol (20% in drinking water or tap water for 2-h sessions during 3 days, and for an additional 4-h session on the 4th day; every week during adolescence, from postnatal day (pnd 28–52. During this period, animals consumed a moderate amount of alcohol despite blood ethanol concentration (BEC did not achieve binge-drinking levels. No withdrawal signs were observed: no changes were observed regarding anxiety-like responses in the elevated plus-maze or plasma corticosterone levels (pnd 53–54. In the novel object recognition (NOR test (pnd 63, a significant deficit in recognition memory was observed in both male and female rats. Western Blot analyses resulted in an increase in the expression of synaptophysin in the frontal cortex (FC of male and female animals, together with a decrease in the expression of the CB2R in the same brain region. In addition, adolescent alcohol induced, exclusively among females, a decrease in several markers of dopaminergic and serotonergic neurotransmission, in which epigenetic mechanisms, i.e., histone acetylation, might be involved. Taken together, further research is still needed to specifically correlate sex-specific brain and behavioral consequences of adolescent alcohol exposure.

  8. [Two cases of giant female urethral stone in long-term bedridden elderly].

    Kato, K; Murase, T; Kuromatsu, I; Hasegawa, M; Kawamura, J

    2001-08-01

    A 78-year-old female suffering from a cerebral infarction and subdural hematoma was referred to us due to a hard mass in the anterior vaginal wall which was disclosed during gynecological examination. An abdominal X-ray, computed tomography (CT) and magnetic resonance imaging (MRI) showed that a large spindle-shaped stone, 60 x 42 mm in size, was impacting the urethra. It was impossible to catheterize the urethra. The stone gradually projected through the external urethral meatus and was removed by grasping and drawing with forceps. Another 83-year-old female with senile dementia was referred to us because of macrohematuria. An abdominal X-ray and CT showed the presence of two oval bladder stones, 32 x 24 mm and 30 x 21 mm in size. During a follow-up, one of the stones projected partially through the external urethral meatus and was removed by drawing with forceps. After a week, the other stone impacted the urethra and was removed in the same way. Both women were frail, bedridden institutionalized elderly with severe dementia, and their urination had been managed with diapers for years. As the proportion of elderly people in Japan rapidly increases, female urethral stones migrating from the urinary bladder, once very rare, may increase in number, to which we must pay attention.

  9. Effect of long-term caloric restriction on brain monoamines in aging male and female Fischer 344 rats.

    Kolta, M G; Holson, R; Duffy, P; Hart, R W

    1989-05-01

    The present study examines the changes in central monoamines and their metabolites in aged male and female rats after long-term caloric restriction. Fischer 344 rats of both sexes (n = 5-10/group) were maintained on one of two dietary regimens: ad libitum NIH 31 diet or 60% by weight of the ad lib. intake (restricted), supplemented with vitamins and minerals. Animals received these diets from the age of 14 weeks until killed at 22.25 months of age. Caudate nucleus (CN), hypothalamus (HYPO), olfactory bulb (OB) and nucleus accumbens (NA) were assayed for content of norepinephrine (NE), dopamine (DA) and its metabolites (dihydroxyphenylacetic acid, DOPAC, and homovanillic acid, HVA) and serotonin (5-HT) and its metabolite 5-hydroxyindoleacetic acid (5-HIAA) using HPLC/EC. Relative to the ad lib. group, restricted rats of both sex showed significant decreases in NE content in CN, HYPO and OB. DA and 5-HT content were decreased significantly in the CN and HYPO. No significant changes were found in the levels of DA metabolites in all brain regions studied. While the 5-HIAA level was significantly reduced in the HYPO and NA of the female restricted rats, it was increased several-fold in the OB of the male restricted animals. These preliminary results suggest that long-term caloric restriction alters brain monoamine concentrations, an effect which may in turn modify the normal rate of aging.

  10. Post-learning stress enhances long-term memory and differentially influences memory in females depending on menstrual stage.

    Zoladz, Phillip R; Peters, David M; Cadle, Chelsea E; Kalchik, Andrea E; Aufdenkampe, Rachael L; Dailey, Alison M; Brown, Callie M; Scharf, Amanda R; Earley, McKenna B; Knippen, Courtney L; Rorabaugh, Boyd R

    2015-09-01

    Most work has shown that post-learning stress enhances long-term memory; however, there have been recent inconsistencies in this literature. The purpose of the present study was to examine further the effects of post-learning stress on long-term memory and to explore any sex differences that may exist. Male and female participants learned a list of 42 words that varied in emotional valence and arousal level. Following encoding, participants completed a free recall assessment and then submerged their hand into a bath of ice cold (stress) or lukewarm (no stress) water for 3 min. The next day, participants were given free recall and recognition tests. Stressed participants recalled more words than non-stressed participants 24h after learning. Stress also enhanced female participants' recall of arousing words when they were in the follicular, but not luteal, phase. These findings replicate previous work examining post-learning stress effects on memory and implicate the involvement of sex-related hormones in such effects. Copyright © 2015 Elsevier B.V.

  11. Experiences of long-term home care as an informal caregiver to a spouse: gendered meanings in everyday life for female carers.

    Eriksson, Henrik; Sandberg, Jonas; Hellström, Ingrid

    2013-05-01

    In this article, we explore the gender aspects of long-term caregiving from the perspective of women providing home care for a spouse suffering from dementia. One of the most common circumstances in which a woman gradually steps into a long-term caregiver role at home involves caring for a spouse suffering from dementia. Little attention has been paid to examining the experiences and motivations of such caregivers from a feminist perspective. Twelve women, all of whom were informal caregivers to a partner suffering from dementia, were interviewed on the following themes: the home, their partner's disease, everyday life, their relationship and autonomy. The results of these interviews were analysed in relation to gender identity and social power structures using a feminist perspective. The findings of this study show that the informants frequently reflected on their caregiving activities in terms of both general and heteronormative expectations. The results suggest that the process of heteropolarisation in these cases can be an understood as a consequence of both the spouse's illness and the resulting caring duties. Also, the results suggest that the act of caring leads to introspections concerning perceived 'shortcomings' as a caregiver. Finally, the results indicate that it is important to recognise when the need for support in day-to-day caring is downplayed. Women view their caregiving role and responsibilities as paramount; their other duties, including caring for themselves, are deemed less important. We stress that the intense commitment and responsibilities that women experience in their day-to-day caring must be acknowledged and that it is important for healthcare professionals to find mechanisms for providing choices for female caregivers without neglecting their moral concerns. Female carers face difficulties in always living up to gendered standards and this need to be considered when evaluating policies and practices for family carers. © 2012 Blackwell

  12. A United States perspective on long-term management of areas contaminated with radioactive materials.

    Jones, C Rick

    2004-01-01

    The US has far-reaching and extensive experience in the long-term management of areas contaminated with radioactive materials. This experience base includes the Department of Energy's continued follow-up with Hiroshima and Nagasaki from the 1940s at the Radiological Effects Research Foundation in Hiroshima, Japan, the long-term management of the Marshall Islands Programme, the clean-up of the US nuclear weapons complex and the ongoing management of accident sites such as in Palomares, Spain. This paper discusses the lessons learnt and best practices gained from this far-reaching and extensive experience in the long-term management of areas contaminated with radioactive materials.

  13. Prenatal alcohol exposure results in long-term serotonin neuron deficits in female rats: modulatory role of ovarian steroids.

    Sliwowska, Joanna H; Song, Hyun Jung; Bodnar, Tamara; Weinberg, Joanne

    2014-01-01

    Previous studies on male rodents found that prenatal alcohol exposure (PAE) decreases the number of serotonin immunoreactive (5-HT-ir) neurons in the brainstem. However, data on the effects of PAE in females are lacking. In light of known sex differences in responsiveness of the 5-HT system and known effects of estrogen (E2 ) and progesterone (P4 ) in the brain, we hypothesized that sex steroids will modulate the adverse effects of PAE on 5-HT neurons in adult females. Adult females from 3 prenatal groups (Prenatal alcohol-exposed [PAE], Pair-fed [PF], and ad libitum-fed Controls [C]) were ovariectomized (OVX), with or without hormone replacement, or underwent Sham OVX. 5-HT-ir cells were examined in key brainstem areas. Our data support the hypothesis that PAE has long-term effects on the 5-HT system of females and that ovarian steroids have a modulatory role in these effects. Intact (Sham OVX) PAE females had marginally lower numbers of 5-HT-ir neurons in the dorsal raphe nucleus of the brainstem compared with PF and C females. This marginal difference became significant following removal of hormones by OVX. Replacement with E2 restored the number of 5-HT-ir neurons in PAE females to control levels, while P4 reversed the effects of E2 . Importantly, despite these differential responses of the 5-HT system to ovarian steroids, there were no differences in E2 and P4 levels among prenatal treatment groups. These data demonstrate long-term, adverse effects of PAE on the 5-HT system of females, as well as differential sensitivity of PAE compared with control females to the modulatory effects of ovarian steroids on 5-HT neurons. Our findings have important implications for understanding sex differences in 5-HT dysfunction in depression/anxiety disorders and the higher rates of these mental health problems in individuals with fetal alcohol spectrum disorder.

  14. Long-term effects of prenatal x-ray of human females: reproductive experience

    Meyer, M.B.; Tonascia, J.

    1981-01-01

    A cohort of singleton black human females exposed to diagnostic x-ray in utero and controls matched by parity, hospital of birth and birthdate have been followed to ages 25 to 30 years in Baltimore, Maryland. The search for possible effects of prenatal irradiation has focused on health, growth, development, and reproductive experience of exposed and control women. This paper reports findings related to reproductive experience. From an original data set of 1458 matched exposed-control pairs of women, questionnaire responses were received from 1109 exposed and 1124 control women including 852 each from pairs in which both the exposed and control woman responded. After careful search for alternative explanations of the findings, the authors concluded that females exposed in utero to low doses of x-ray (probably 1 to 5 rads) had significant increases in their rates of early onset of menses, births at age 15 years or less, numbers of living children, stillbirths, and sterilizing operations by their mid-twenties. These findings are compatible with animal studies in which prenatal irradiation kills many oocytes, but accelerates the development of remaining cells to stages more closely correlated with fertility. Although these animals subsequently became sterile, this cannot be tested in the current study because significantly more of the irradiated women have had surgical sterilizations

  15. Long-term effects of prenatal X ray on development and fertility of human females

    1976-01-01

    This continuing epidemiologic study investigates possible effects of X-ray exposure during foetal life on the subsequent development and fertility of human females and on their offspring. The study population comprises 1458 females exposed in utero to maternal diagnostic X ray such as pelvimetry, and 1458 unexposed controls matched by hospital of birth, parity, race and birthdate (1947-1952). Phase I of the study showed a 10-15% increase in fertility in young exposed women, based on ascertainment of live births and foetal deaths registered in Baltimore City. This statistically significant difference (p=0.011) remained after adjustment for differences between exposed and control women in economic, social and medical factors. Phase II of the study, a direct follow-up of exposed control pairs of women now aged 22-28, continues to show more total pregnancies among exposed women. Exposed-in-utero women had 15% more total pregnancies than controls in 1960-1969, and 7% more in 1970-1975. Exposed and control women are similar in number of siblings, number of children wanted, contraceptive use, and frequency of therapeutic abortion. Other findings suggest possible exposed-control differences in growth, development and behaviour. Exposed women have completed fewer grades of school, have poorer general health, more menstrual problems, more of certain diseases and accidents, and are heavier for height than controls. (author)

  16. Influence of lifestyle factors on long-term sickness absence among female healthcare workers

    Quist, Helle Gram; Thomsen, Birthe L; Christensen, Ulla

  17. Long-term ophthalmic health care in Usher syndrome type I from an ICF perspective.

    Möller, Kerstin; Eriksson, Kristina; Sadeghi, André M; Möller, Claes; Danermark, Berth

    2009-01-01

    The aim was to explore ophthalmic health care in female patients with Usher Syndrome type I (USH I) over 20 years and to evaluate the relationship between the ophthalmic health care and the health state of the patients from a health perspective. A retrospective study of records from ophthalmology departments (OD) and low vision clinics (LVC) from 1985 to 2004. Assessment of the reports was performed based on the International Classification of Functioning, Disability and Health (ICF). Findings were analysed by manifest content analysis with ICF as a framework and using four themes: health care system, procedure examinations, patient's functioning and disability and procedure actions. The records of nine female patients (aged 25-39 years, 1985) with USH I were selected from the national database of USH. A great number of notes were collected (OD 344 and LVC 566). Procedure examinations were exclusively oriented towards body structure and function. All patients showed aggravated visual impairment over and above the hearing and vestibular impairment. Procedure actions were oriented towards environmental factors. No correlation was found between procedures performed and patient's experience of disability. The high degree of resource allocation was not correlated to the patients' impairment. The study indicates that the ophthalmic health care was characterised by inefficiency. This conclusion is very serious because patients very likely face severe disability and emotional difficulties. ICF is ought to be incorporated in ophthalmic health care strategy to improve the health care.

  19. Vitamin D and the Promotion of Long-Term Metabolic Health from a Programming Perspective

    Saranya Palaniswamy

    2015-01-01

    Full Text Available Studies linking vitamin D and long-term metabolic health have generated much debate. Recommendations for the intake of vitamin D by the general public and by the health care professionals have been complicated by a number of inconsistencies in the literature. These caveats relate to the methodological approaches, differences in the populations (and the species of study, and the definitions used for thresholds of vitamin D status. This review addresses current evidence available for assessing the potential programming of long-term metabolic health of offspring by maternal vitamin D status in pregnancy. It summarizes knowledge on the early origins of metabolic health and analyzes evidence for an association between the vitamin D status in pregnancy and maternal and fetal health status. In addition, we analyze the link between the regulation of inflammation and the vitamin D status in the general population to inform on the general mechanisms through which early vitamin D might affect the programming of long-term health. The evidence suggests an association between the vitamin D status in early life and the programming of long-term health. However, to the best of our knowledge, the current finding is insufficient to draw a final conclusion for evidence-based preventive actions. The data warrant replication in prospective studies and additional research substantiating the causal factors and pathways.

  1. Are female children more vulnerable to the long-term effects of maternal depression during pregnancy?

    Quarini, Catherine; Pearson, Rebecca M; Stein, Alan; Ramchandani, Paul G; Lewis, Glyn; Evans, Jonathan

    2016-01-01

    Female fetuses are more vulnerable to high levels of maternal glucocorticoids. We examined whether exposure to prenatal maternal depression, a condition associated with high glucocorticoids, carries greater risk for depression at 12 and 18 years in girls. Our sample comprised 7959 mothers and children from the Avon Longitudinal Study of Parents and Children following imputation for missing data. Maternal depression was assessed pre-and post-natally, and offspring depression at ages 12 and 18. We used logistic regression models to examine the relationship between exposure to prenatal and postnatal depression and offspring depression at 18 and 12 and interactions with gender. There was an interaction between prenatal depression and gender (P=0.027) and between postnatal depression and gender (P=0.027) for offspring depression at 18. Following adjustment in pre-natally depressed mothers, the odds ratio for offspring depression at 18 was 1.55 (95% c.i. 1.03-2.34) for girls and 0.54 (0.23-1.26) for boys. In post-natally depressed mothers, the odds ratio for offspring depression at 18 was 1.15 (0.70-1.89) in girls and 3.13 (1.52-6.45) in boys. However there was no evidence for interaction between prenatal or postnatal depression and gender (P=0.559 and 0.780 respectively) for offspring depression at 12. As expected with this large cohort spanning over 18 years, there was loss-to-follow-up. This is the first evidence in humans that increased vulnerability of female fetuses to maternal stress responses during pregnancy persists into adolescence. One explanation for gender differences emerging later is more depressive symptomatology is attributed to heritable risk at 12, whereas biological processes involved in brain development at 18 may be influenced by foetal programming. If replicated, this study has potential to help understand intergenerational transmission of depression, a leading cause of morbidity worldwide. Copyright © 2015 The Authors. Published by Elsevier B

  2. A United States perspective on long term management of areas contaminated with radioactive materials

    Jones, C.R.

    2003-01-01

    Full text: The United States has far-reaching experience in the long-term management of areas contaminated with radioactive materials. The events resulting from the atmospheric testing of nuclear weapons in the Marshall Islands, follow-up from Hiroshima and Nagasaki, accidents, and the environmental cleanup of our weapons complex have resulted in an extensive body of lessons learned and best practices. The lack of trust created in the affected population, regardless of cause of the spread of radioactive material, creates the working environment for long-term management of the situation. The extent of advanced planning for such an event will define and bound your ultimate success in reaching a conclusion acceptable to the affected parties. The two key issues to be addressed in the long-term management of areas contaminated with radioactive materials are the two 'T's' - technical and trust. The technical issues to be resolved include: access to the affected area; infrastructure to support operations; local and imported staffing; health care for the affected population; and payment to name a few. In addressing the issue of trust it is critical to establish open, honest and inclusive communications and decision making with the affected population and stakeholders, with clear roles and responsibilities defined. Actions must be sensitive to local cultural issues and agreements reached with affected populations prior to actions being taken. Establishment of an alternative views resolution process helps build trust and allow actions to taken. Government to government relations and agreements must be established with an acceptance and understanding of the long term investment in time and resources needed. Planning ahead for such an eventuality and putting in place procedures, agreements and resources needed to address the technical and trust issues associated with the long-term management of areas contaminated with radioactive materials enhances success.

  3. The stability of the international oil trade network from short-term and long-term perspectives

    Sun, Qingru; Gao, Xiangyun; Zhong, Weiqiong; Liu, Nairong

    2017-09-01

    To examine the stability of the international oil trade network and explore the influence of countries and trade relationships on the trade stability, we construct weighted and unweighted international oil trade networks based on complex network theory using oil trading data between countries from 1996 to 2014. We analyze the stability of international oil trade network (IOTN) from short-term and long-term aspects. From the short-term perspective, we find that the trade volumes play an important role on the stability. Moreover, the weighted IOTN is stable; however, the unweighted networks can better reflect the actual evolution of IOTN. From the long-term perspective, we identify trade relationships that are maintained during the whole sample period to reveal the situation of the whole international oil trade. We provide a way to quantitatively measure the stability of complex network from short-term and long-term perspectives, which can be applied to measure and analyze trade stability of other goods or services.

    PurposeThe aim of this retrospective study was to analyze the long-term outcome of peripherally implanted venous access ports in the forearm at our institution in a female patient collective.MethodsBetween June 2002 and May 2011, a total of 293 female patients with an underlying malignancy had 299 forearm ports implanted in our interventional radiology suite. The mean age of the cohort was 55 ± 12 years (range 26–81 years). The majority of women suffered from breast (59.5 %) or ovarian cancer (28.1 %). Complications were classified as infectious complications, thrombotic and nonthrombotic catheter dysfunction (dislocation of the catheter or port chamber, fracture with/without embolization or kinking of the catheter, port occlusion), and others.ResultsWe analyzed a total of 90,276 catheter days in 248 port systems (47 patients were lost to follow-up). The mean device service interval was 364 days per catheter (range 8–2,132, median 223 days, CI 311–415, SD 404). Sixty-seven early (≤30 days from implantation) or late complications (>30 days) occurred during the observation period (0.74/1,000 catheter days). Common complications were port infection (0.18/1,000 days), thrombotic dysfunction (0.12/1,000 days), and skin dehiscence (0.12/1,000 days). Nonthrombotic dysfunction occurred in a total of 21 cases (0.23/1,000 days) and seemed to cumulate on the venous catheter entry site on the distal upper arm.ConclusionPeripherally implanted venous access ports in the forearm are a safe alternative to chest or upper-arm ports in female oncology patients. Special attention should be paid to signs of skin dehiscence and nonthrombotic dysfunction, especially when used for long-term treatment.

  5. ADRA2B deletion variant selectively predicts stress-induced enhancement of long-term memory in females.

    Zoladz, Phillip R; Kalchik, Andrea E; Hoffman, Mackenzie M; Aufdenkampe, Rachael L; Lyle, Sarah M; Peters, David M; Brown, Callie M; Cadle, Chelsea E; Scharf, Amanda R; Dailey, Alison M; Wolters, Nicholas E; Talbot, Jeffery N; Rorabaugh, Boyd R

    Clarifying the mechanisms that underlie stress-induced alterations of learning and memory may lend important insight into susceptibility factors governing the development of stress-related psychological disorders, such as post-traumatic stress disorder (PTSD). Previous work has shown that carriers of the ADRA2B Glu(301)-Glu(303) deletion variant exhibit enhanced emotional memory, greater amygdala responses to emotional stimuli and greater intrusiveness of traumatic memories. We speculated that carriers of this deletion variant might also be more vulnerable to stress-induced enhancements of long-term memory, which would implicate the variant as a possible susceptibility factor for traumatic memory formation. One hundred and twenty participants (72 males, 48 females) submerged their hand in ice cold (stress) or warm (no stress) water for 3min. Immediately afterwards, they studied a list of 42 words varying in emotional valence and arousal and then completed an immediate free recall test. Twenty-four hours later, participants' memory for the word list was examined via free recall and recognition assessments. Stressed participants exhibiting greater heart rate responses to the stressor had enhanced recall on the 24-h assessment. Importantly, this enhancement was independent of the emotional nature of the learned information. In contrast to previous work, we did not observe a general enhancement of memory for emotional information in ADRA2B deletion carriers. However, stressed female ADRA2B deletion carriers, particularly those exhibiting greater heart rate responses to the stressor, did demonstrate greater recognition memory than all other groups. Collectively, these findings implicate autonomic mechanisms in the pre-learning stress-induced enhancement of long-term memory and suggest that the ADRA2B deletion variant may selectively predict stress effects on memory in females. Such findings lend important insight into the physiological mechanisms underlying stress

  6. Changes in the female arcuate nucleus morphology and neurochemistry after chronic ethanol consumption and long-term withdrawal.

    Rebouças, Elce C C; Leal, Sandra; Silva, Susana M; Sá, Susana I

    2016-11-01

    Ethanol is a macronutrient whose intake is a form of ingestive behavior, sharing physiological mechanisms with food intake. Chronic ethanol consumption is detrimental to the brain, inducing gender-dependent neuronal damage. The hypothalamic arcuate nucleus (ARN) is a modulator of food intake that expresses feeding-regulatory neuropeptides, such as alpha melanocyte-stimulating hormone (α-MSH) and neuropeptide Y (NPY). Despite its involvement in pathways associated with eating disorders and ethanol abuse, the impact of ethanol consumption and withdrawal in the ARN structure and neurochemistry in females is unknown. We used female rat models of 20% ethanol consumption for six months and of subsequent ethanol withdrawal for two months. Food intake and body weights were measured. ARN morphology was stereologically analyzed to estimate its volume, total number of neurons and total number of neurons expressing NPY, α-MSH, tyrosine hydroxylase (TH) and estrogen receptor alpha (ERα). Ethanol decreased energy intake and body weights. However, it did not change the ARN morphology or the expression of NPY, α-MSH and TH, while increasing ERα expression. Withdrawal induced a significant volume and neuron loss that was accompanied by an increase in NPY expression without affecting α-MSH and TH expression. These findings indicate that the female ARN is more vulnerable to withdrawal than to excess alcohol. The data also support the hypothesis that the same pathways that regulate the expression of NPY and α-MSH in long-term ethanol intake may regulate food intake. The present model of long-term ethanol intake and withdrawal induces new physiological conditions with adaptive responses. Copyright © 2016 Elsevier B.V. All rights reserved.

  7. Perspectives for hydropower stations in Switzerland: long-term competitiveness and possibilities for improvement

    Filippini, M.; Banfi, S.; Luchsinger, C.; Wild, J.; Balmer, M.; Grand, D.; Henkels, L.; Semadeni, M.; Gnansounou, E.

    2001-01-01

    This first general study - which has the character of a preliminary study - examines the questions if the liberalisation of the electricity market will have a negative effect on the competitiveness of hydropower in the long-term and what measures can be taken against such effects. Long-term competitiveness is defined as the ability of a business in this sector to make investments in renewal in the long-term, i.e. after its concessions have expired. The three main aims of the study are: 1. Assessment of the long-term competitiveness of the sector and identification of the factors which could either have a negative effect on it or improve it, 2. Analysis of cost structures and presentation of measures through which the long-term competitiveness of the sector can be reinforced, 3. Presentation of possible political measures to be taken in this business area in order to improve the long-term competitiveness of hydropower stations. The study identifies the most important factors that determine future competitiveness as being the market prices for electricity and capital costs (depreciation and interest on own and borrowed capital). Further, water fees, taxes and regulations concerning residual water flow can be of great importance for investment decisions, in particular for those enterprises that operate close to their profitability limits. The results of the analysis indicate that, in the future, a considerable number of enterprises must be reckoned with that will refrain from renewing their plant. Such outcomes depend, of course, on developments in electricity market prices, specific investment costs, rates of interest and other economic, political, and legal conditions. Making a prognosis about the development of such parameters is linked with a high degree of uncertainty. By means of sensitivity calculations and the definition of various scenarios, attempts are made to take these uncertainties into account . Finally, the study makes reference to the fact that

  8. Long term effects of prenatal X ray on human females: early fertility and frequency of operations to prevent pregnancy

    Meyer, M.B.; Tonascia, J.A.

    1980-01-01

    The subject of this paper is a long-term epidemiological study of human females who were exposed to radiation from maternal diagnostic x-ray procedures when they were in utero, compared with matched, unexposed controls. The study was designed to investigate possible effects of in-utero exposure, with particular interest being paid to reproductive capacity. In the human female and other mammals, because all mitotic divisions of germ cells occur during fetal life, the female baby is born with a finite supply of oocytes and future eggs. This supply is continuously depleted throughout life by ovulation and by cell degeneration, and there is no way for damaged or lost cells to be replaced. Experimental studies in a number of species have shown that female germ cells are extremely sensitive to radiation damage at two times during development. In humans the first of these probably occurs at around 4 to 5 months of gestation, and the second probably occurs around the time of birth. Radiation damage at these sensitive stages might show up at puberty ad during reproductive life, and might be detected by a well-designed study

  9. Long-term storage of radioactive waste: IAEA perspectives on safety and sustainability

    Rowat, J.H.; Louvat, D.; Metcalf, P.E.

    2006-01-01

    As the amounts of radioactive waste in surface storage have increased, concern has grown over the safety and sustainability of storage in the long term. In response to increasing concerns, the International Atomic Energy Agency (IAEA) has included an action to address the safety implications of the long-term storage (LTS) of radioactive waste in its action plan for waste safety; the action plan was endorsed by the IAEA's Member States in 2001. In 2003, the IAEA published a position paper on the safety and sustainability of LTS as part fulfilment of the action in question. A key theme of the position paper is the contrast of safety and sustainability implications of LTS with those of disposal. The present paper provides a summary of the position paper, describes current IAEA activities that deal with the subject of LTS, and discusses findings from the 2004 Cordoba symposium on disposal of low activity radioactive waste that pertain to LTS.

    Long-term capacity expansion models of the U.S. electricity sector have long been used to inform electric sector stakeholders and decision-makers. With the recent surge in variable renewable energy (VRE) generators — primarily wind and solar photovoltaics — the need to appropriately represent VRE generators in these long-term models has increased. VRE generators are especially difficult to represent for a variety of reasons, including their variability, uncertainty, and spatial diversity. This report summarizes the analyses and model experiments that were conducted as part of two workshops on modeling VRE for national-scale capacity expansion models. It discusses the various methods for treating VRE among four modeling teams from the Electric Power Research Institute (EPRI), the U.S. Energy Information Administration (EIA), the U.S. Environmental Protection Agency (EPA), and the National Renewable Energy Laboratory (NREL). The report reviews the findings from the two workshops and emphasizes the areas where there is still need for additional research and development on analysis tools to incorporate VRE into long-term planning and decision-making. This research is intended to inform the energy modeling community on the modeling of variable renewable resources, and is not intended to advocate for or against any particular energy technologies, resources, or policies.

    This thesis is an interpretive analysis of experts' perspectives on the climate implications of New England's reliance on natural gas for electricity generation. Specifically, this research, conducted through interviews and literature review, examines experts' opinions on the desired role of natural gas within the regional electricity sector, alternative energy resources, and state and regional policy opportunities toward the achievement of New England's ambitious long-term greenhouse gas reduction goals. Experts expressed concern about the climate dilemma posed by a dependence on natural gas. However, interviews revealed that short-term reliability and cost considerations are paramount for many experts, and therefore a reliance on natural gas is the existing reality. To incentivize renewable generation technologies for the purposes of long-term climate stabilization, experts advocated for the expanded implementation of renewable portfolio standard, net metering, and feed-in tariff policies. More broadly, interviewees expressed the need for an array of complementary state and regional policies.

    Long-term capacity expansion models of the U.S. electricity sector have long been used to inform electric sector stakeholders and decision makers. With the recent surge in variable renewable energy (VRE) generators - primarily wind and solar photovoltaics - the need to appropriately represent VRE generators in these long-term models has increased. VRE generators are especially difficult to represent for a variety of reasons, including their variability, uncertainty, and spatial diversity. To assess current best practices, share methods and data, and identify future research needs for VRE representation in capacity expansion models, four capacity expansion modeling teams from the Electric Power Research Institute, the U.S. Energy Information Administration, the U.S. Environmental Protection Agency, and the National Renewable Energy Laboratory conducted two workshops of VRE modeling for national-scale capacity expansion models. The workshops covered a wide range of VRE topics, including transmission and VRE resource data, VRE capacity value, dispatch and operational modeling, distributed generation, and temporal and spatial resolution. The objectives of the workshops were both to better understand these topics and to improve the representation of VRE across the suite of models. Given these goals, each team incorporated model updates and performed additional analyses between the first and second workshops. This report summarizes the analyses and model 'experiments' that were conducted as part of these workshops as well as the various methods for treating VRE among the four modeling teams. The report also reviews the findings and learnings from the two workshops. We emphasize the areas where there is still need for additional research and development on analysis tools to incorporate VRE into long-term planning and decision-making.

  15. Long-term monitoring of fecal steroid hormones in female snow leopards (Panthera uncia during pregnancy or pseudopregnancy.

    Kodzue Kinoshita

    Full Text Available Knowledge of the basic reproductive physiology of snow leopards is required urgently in order to develop a suitable management conditions under captivity. In this study, the long-term monitoring of concentrations of three steroid hormones in fecal matter of three female snow leopards was performed using enzyme immunoassays: (1 estradiol-17β, (2 progesterone and (3 cortisol metabolite. Two of the female animals were housed with a male during the winter breeding season, and copulated around the day the estradiol-17β metabolite peaked subsequently becoming pregnant. The other female was treated in two different ways: (1 first housed with a male in all year round and then (2 in the winter season only. She did not mate with him on the first occasion, but did so latter around when estradiol-17β metabolite peaked, and became pseudopregnant. During pregnancy, progesterone metabolite concentrations increased for 92 or 94 days, with this period being approximately twice as long as in the pseudopregnant case (31, 42, 49 and 53 days. The levels of cortisol metabolite in the pseudopregnant female (1.35 µg/g were significantly higher than in the pregnant females (0.33 and 0.24 µg/g (P<0.05. Similarly, during the breeding season, the levels of estradiol-17β metabolite in the pseudopregnant female (2.18 µg/g were significantly higher than those in the pregnant females (0.81 and 0.85 µg/g (P<0.05. Unlike cortisol the average levels of estradiol-17β during the breeding season were independent of reproductive success.The hormone levels may also be related to housing conditions and the resulting reproductive success in female leopards. The female housed with a male during the non-breeding season had high levels of cortisol metabolites and low levels of estradiol-17β in the breeding season, and failed to become pregnant. This indicates that housing conditions in snow leopards may be an important factor for normal endocrine secretion and resulting breeding

    A qualitative approach was used in the exploration of meaning in life for long-term care (LTC) residents. This hermeneutic phenomenological study, as described by van Manen, was conducted using semi-structured interviews with 11 LTC residents from a rural region in Atlantic Canada. Four themes emerged as enhancing meaning in life for the residents in this study: Connectedness, Survival Despite Declining Functional Capacity, Engaging in "Normal" Activities, and Seeking a Place of Refuge. In this article, we describe the emerging themes and the implications for LTC education, practice, and future research. Copyright 2012, SLACK Incorporated.

  17. Long-term doctor-patient relationships: patient perspective from online reviews.

    Detz, Alissa; López, Andrea; Sarkar, Urmimala

    2013-07-02

    Continuity of patient care is one of the cornerstones of primary care. To examine publicly available, Internet-based reviews of adult primary care physicians, specifically written by patients who report long-term relationships with their physicians. This substudy was nested within a larger qualitative content analysis of online physician ratings. We focused on reviews reflecting an established patient-physician relationship, that is, those seeing their physicians for at least 1 year. Of the 712 Internet reviews of primary care physicians, 93 reviews (13.1%) were from patients that self-identified as having a long-term relationship with their physician, 11 reviews (1.5%) commented on a first-time visit to a physician, and the remainder of reviews (85.4%) did not specify the amount of time with their physician. Analysis revealed six overarching domains: (1) personality traits or descriptors of the physician, (2) technical competence, (3) communication, (4) access to physician, (5) office staff/environment, and (6) coordination of care. Our analysis shows that patients who have been with their physician for at least 1 year write positive reviews on public websites and focus on physician attributes.

  18. Market structure in the US electricity industry: a long-term perspective

    Kamerschen, D.R.

    2005-01-01

    We estimate changes in market structure in the US electric power industry during the last three decades using two independent approaches. First, we estimate an industry-wide conjectural-variations parameter. We find that industry concentration was generally rising during the 1970s but has been gradually and consistently falling since the early 1980s. To check the robustness of these results, we then use a translog production function to estimate the Lerner Index. The results confirm that the industry was becoming less concentrated during the 1980s, though the Lerner Index tended to fluctuate during the late 1980s and early 1990s. Our results suggest that the current state of the electricity industry may have more to do with long-term changes in market structure than recent attempts to establish competitive wholesale electricity markets.

  19. Energy development and environment: What about solar energy in a long term perspective?

    Dessus, Benjamin; Pharabod, Francois

    After decades of strong growth, the next century might be that in which the world population is stabilized around 11 billion inhabitants. Next century's main concerns include the development hoped for the probable consequences of an increase of the greenhouse effect due to main induced emissions, and the risks posed by possible dissemination of nuclear energy to all the regions of the globe. In order to shed some light on these questions, we propose an energy scenario, based on an analysis of evolution of demographics, energy needs, renewable and fossil reserves, environmental issues, technological possibilities and regional imbalances. This scenario shows that solar energy could contribute significantly in the long term energy mix. We discuss the respective advantages and drawbacks of the different solar technologies: solar power satellites, ground solar power plants and decentralized applications, as they to the needs that must be satisfied.

  20. Long-term perspectives on giant earthquakes and tsunamis at subduction zones

    Satake, K.; Atwater, B.F.; ,

    2007-01-01

    Histories of earthquakes and tsunamis, inferred from geological evidence, aid in anticipating future catastrophes. This natural warning system now influences building codes and tsunami planning in the United States, Canada, and Japan, particularly where geology demonstrates the past occurrence of earthquakes and tsunamis larger than those known from written and instrumental records. Under favorable circumstances, paleoseismology can thus provide long-term advisories of unusually large tsunamis. The extraordinary Indian Ocean tsunami of 2004 resulted from a fault rupture more than 1000 km in length that included and dwarfed fault patches that had broken historically during lesser shocks. Such variation in rupture mode, known from written history at a few subduction zones, is also characteristic of earthquake histories inferred from geology on the Pacific Rim.

    Hines, Harrison G; Avila, Cynthia J; Rudakevych, Tanya M; Curlin, Farr A; Yoon, John D

    2017-11-01

    Shifts in the healthcare environment have introduced challenges to the long-term continuity of the doctor-patient relationship. This study examines whether certain demographic or religious characteristics of physicians are associated with maintaining long-term relationships (LTRs) and/or friendships with their patients and describes physicians' opinions regarding the influence of such patient relationships on health outcomes. In 2011, survey responses were obtained from 1289 US physicians from various specialties. Physicians answered 8 items that assessed their opinions regarding their friendships, sense of meaningfulness, and experience in LTRs. The χ 2 test was used to examine bivariate associations between each demographic characteristic and physician responses to the importance of LTRs. The survey included 2 questions about the duration of physician practice and the number of patients seen in a typical week, 4 questions about perceived meaningfulness and friendship in the doctor-patient relationship, and 2 questions about the doctor-patient relationship setting. The adjusted survey response rate was 69% (1289/1863), 43% of physicians indicated that many or most of their patient relationships are LTRs, and 13.7% indicated they consider many or most of their patients to be friends. Just fewer than half of physicians (45.1%) perceive LTRs to have a great impact on clinical outcomes, 64.8% believe that LTRs contribute to patient trust, and 52.2% believe that LTRs are more likely to cause a patient to follow a physician's medical recommendations. This study presents a representative picture of US physicians' perceptions regarding relationships with patients. Physicians generally perceive LTRs to have a positive impact on patients' clinical outcomes, although the majority of physicians report they have few or no such relationships.

  2. Threshold of musculoskeletal pain intensity for increased risk of long-term sickness absence among female healthcare workers in eldercare.

    Lars L Andersen

    Full Text Available PURPOSE: Musculoskeletal disorders increase the risk for absenteeism and work disability. However, the threshold when musculoskeletal pain intensity significantly increases the risk of sickness absence among different occupations is unknown. This study estimates the risk for long-term sickness absence (LTSA from different pain intensities in the low back, neck/shoulder and knees among female healthcare workers in eldercare. METHODS: Prospective cohort study among 8,732 Danish female healthcare workers responding to a questionnaire in 2004-2005, and subsequently followed for one year in a national register of social transfer payments (DREAM. Using Cox regression hazard ratio (HR analysis we modeled risk estimates of pain intensities on a scale from 0-9 (reference 0, where 0 is no pain and 9 is worst imaginable pain in the low back, neck/shoulders and knees during the last three months for onset of LTSA (receiving sickness absence compensation for at least eight consecutive weeks during one-year follow-up. RESULTS: During follow-up, the 12-month prevalence of LTSA was 6.3%. With adjustment for age, BMI, smoking and leisure physical activity, the thresholds of pain intensities significantly increasing risk of LTSA for the low back (HR 1.44 [95%CI 1.07-1.93], neck/shoulders (HR 1.47 [95%CI 1.10-1.96] and knees (HR 1.43 [95%CI 1.06-1.93] were 5, 4 and 3 (scale 0-9, respectively, referencing pain intensity of 0. CONCLUSION: The threshold of pain intensity significantly increasing the risk for LTSA among female healthcare workers varies across body regions, with knee pain having the lowest threshold. This knowledge may be used in the prevention of LTSA among health care workers.

  3. A long-term perspective on anthropogenic activities and management strategies in a prairie wetland

    Multiple stressors to shallow lake/wetland ecosystems have the ability to control the relative stability of alternative states (clear, macrophyte-dominated or turbid, algal dominated). As a consequence, the use of remedial biomanipulations to induce trophic cascades and shift a turbid lake to a clear state is often only a temporary solution. Here we show the instability of short-term manipulations in the shallow Lake Christina (a Class V wetland in the prairie ecoregion of western Minnesota, USA) is governed by the long-term state following a regime shift in the lake. During the modern, managed period of the lake, three top-down manipulations (fish kills) were undertaken inducing temporary (5-10 years) unstable clear-water states. Paleoecological remains of diatoms, along with proxies of primary production (total chlorophyll a and total organic carbon accumulation rate) and trophic state (total P) from sediment records clearly show a single regime shift in the lake during the early 1950s; following this shift, the functioning of the lake ecosystem is dominated by a persistent turbid state. We find that multiple stressors contributed to the regime shift. First, the lake began to eutrophy (from agricultural land use and/or increased waterfowl populations), leading to a dramatic increase in primary production. Soon after, the construction of a dam in 1936 effectively doubled the depth of the lake, compounded by increases in regional humidity; this resulted in an increase in planktivorous and benthivorous fish reducing phytoplankton grazers. These factors further conspired to increase the stability of a turbid regime during the modern managed period, such that switches to a clear-water state were inherently unstable and the lake consistently returned to a turbid state. We conclude that while top-down manipulations have had measurable impacts on the lake state, they have not been effective in providing a return to an ecosystem similar to the stable historical period

  4. The long-term effect of perspective change on the emotional intensity of autobiographical memories.

    Sekiguchi, Takahiro; Nonaka, Saori

    2014-01-01

    Autobiographical memories can be recalled from either a field (first-person) or an observer (third-person) perspective. Previous studies have reported that field-to-observer perspective change reduced the emotional intensity of recalled events. In the present study, we examined whether this effect has a long duration by employing follow-up measurements. The participants were asked to recall the same events repeatedly across three sessions (S1, S2, and S3): S2 was conducted about three days after S1, and S3 was conducted about four weeks after S2. The results showed a reduction in the emotional intensity of the recalled events when the perspective was changed from field to observer at S2. More importantly, this reduction in emotional intensity persisted until S3. These effects were not observed under observer-to-field perspective change at S2. These results suggest that observer perspective taking can cause plastic change in the autobiographical memory system.

  5. [Pay for performance (P4P). Long-term effects and perspectives].

    Schrappe, M; Gültekin, N

    2011-02-01

    After 10 years of experience and research, a wide array of results on evaluation and long-term effects of pay for performance (P4P) programs have been published. These data do not only give insight into most of the problems of implementation, but also into aspects which, in part, may attenuate the high expectations at the beginning of the discussion. P4P programs exhibit a ceiling effect, some improvements are reversed after incentives are cancelled, and improvements show opportunity costs as absent improvements for indicators, which are not object to financial incentives (in some cases for the same disease). These observations can be explained by the hypothesis that P4P programs have characteristics of fee-for-service reimbursement, if symmetric information is available for insurance and provider. P4P programs are local instruments. While integration of healthcare is considered as an important issue, they should be combined with programs and incentives which foster further vertical and horizontal integration. For Germany, further research in the implementation and effects of P4P programs is necessary.

    2012-10-01

    The relative significance of child injury as a cause of preventable death has increased as mortality from infectious diseases has declined. Unintentional child injuries are now a major cause of death and disability across the world with the greatest burden falling on those who are most disadvantaged. A review of long-term data on child injury mortality was conducted to explore trends and inequalities and consider how data were used to inform policy, practice and research. The authors systematically collated and quality appraised data from publications and documents reporting unintentional child injury mortality over periods of 20 years or more. A critical narrative synthesis explored trends by country income group, injury type, age, gender, ethnicity and socioeconomic group. 31 studies meeting the inclusion criteria were identified of which 30 were included in the synthesis. Only six were from middle income countries and none were from low income countries. An overall trend in falling child injury mortality masked rising road traffic injury deaths, evidence of increasing vulnerability of adolescents and widening disparities within countries when analysed by ethnic group and socioeconomic status. Child injury mortality trend data from high and middle income countries has illustrated inequalities within generally falling trends. There is scope for greater use of existing trend data to inform policy and practice. Similar evidence from low income countries where the burden of injury is greatest is needed.

  7. Evolutionist approach of upstream activities competitiveness of the petroleum industry in a long term perspective

    Dos Santos, E.M.

    1997-01-01

    The purpose of this work is to analyze the concept of competitiveness of companies and nations in the upstream sector of the international oil industry, trying to identify the possibilities of future development of this sector as well as the interactions that may exist between different actors such as governments, consumers and oil companies to boost or re-launch the competitive position of their enterprises and countries in the international context of the industry. In order to attain that, we analyze the developments of the most important economic attributes that characterize the oil activity as well as its most crucial political aspects. We develop a model of 'oil competition' and a definition of 'oil competitiveness' that take clearly into consideration both the differences between various oil actors and the dynamic aspects linked to the evolution of the oil industry. We do so by constructing an evolutionist model of competition and competitiveness. This approach emulates a 'biological process' where firms and the economic environment interact with each other within a process similar to 'natural selection' with the survival of the fittest. This evolutionist model adopts some analytical instruments established by Michael Porter, from the University of Harvard, to interpret the changes and the dissimilarities of behavior of various oil actors as well as to explain their respective role in the new oil world that is being organized. Thus, we introduce the notions of 'dominant form of competition' and 'generic strategy of enterprises'. Then, we use our methodology to analyze the past of the oil industry (the stability and the instability). We conclude this work by discussing about the future evolution of the oil activities in the context of a new long term cycle of investment for the sector. (author)

  8. Long-term effects of whole-body vibration training in high-level female basketball players.

    Fernandez-Rio, J; Terrados, N; Suman, O

    2012-02-01

    The aim of this study was to investigate the long-term effects of Whole-Body Vibration (WBV) training on the jumping capabilities of high-level female basketball players. A 12-week WBV program was applied to 10 national and international level female basketball players. They were randomly distributed into a control group (CG: 23.2±3.96 years, 69.64±11.17 kg, 179.7±7.96 cm) and an experimental group (VG: 24.0±2.65 years, 70.17±9.86 kg, 181.9±10.83 cm). In order to determine the effects of the WBV program on the jumping capabilities of the subjects, the following tests were used: SJ, CMJ, ACMVJ, and 15-seconds maximal jump. In the SJ test, the CG significantly increased from 455.4±25.91 to 476.6±26.6 ms (+4.42%; P=0.05), while the VG also increased significantly from 455±15.62 to 478.33±16.56 ms (+5.13%; P=0.02). In the CMJ test, the CG significantly increased from 470.2±12.15 to 496±23.38 ms (+5.49%; P=0.04), while the VG remained unchanged: 472±15.62 to 474.67±8.74 ms (+0.76%). In the ACMVJ test, the CG increased from 514±37.67 to 520±15.5 ms (+1.42%), while the VG decreased from 515±31.43 to 510.33±16.56 ms (-0.77%). In the 15-seconds jump test, the CG increased from 459±23.48 to 481.6±15.53 ms (+5.15%), while the VG increased from 464±36.66 to 471±33.96 ms (+1.6%). In this same test, the power generated by the CG increased from 20.01±1.84 to 22.14±2.21 W/kg (+11.12%), while the VG increased from 17.28±2.39 to 22.21±5.82 W/kg (+29.7%). WBV has no extra appreciable effect or benefit on the jumping capabilities of high-level female basketball players compared to regular strength training methods.

  9. Perspectives for long-term competition in the central European electricity market

    Haas, Reinhard

    2005-01-01

    In this paper we focus on the Central European electricity market and analyse whether liberalization, deregulation, and privatization are sufficient to bring about real competition. Moreover, we discuss the relevance of the following conditions to bring about real competition and to avoid market power: 1) A rigorous correct un bundling; 2) excess capacities in transmission; 3) excess capacities in generation; 4) a large number of generators and suppliers; 5) the balanced existence of short-term (e.g. spot markets) and long-term markets (e.g. bilateral contracts, forwards); 6) full liberalization; Some major findings of this analysis are: 1) Currently, demand is continuously increasing while capacities are shut down. At least in 2009 demand will have caught up with generation capacities. This could lead to severe price spikes. 2) The Central European electricity market is separated from other markets by means of limited transmission capacities; 3) With respect to effective competition in Central Europe the major problems are: i) a very small (and continuously decreasing) number of generators, and ii) a lack of serious un bundling between generation and transmission mainly in Germany; This leads to cross-subsidization of generation by the network operation and to a heavy discrimination of other and new generators; 4) Moreover, a crucial condition for active competition is a sufficiently large transmission grid. Yet, currently especially at the border to the new EU member countries transmission capacities are rather scarce and there are no signs of extensions of the grid. This also limits the access of countries with potential excess capacities like Ukraine, Bulgaria, Romania to the Central European market The major conclusion of this analysis is: All conditions investigated above must be fulfilled simultaneously to bring about a competitive electricity market in Western Europe and the extended European Union. If only one of these conditions is missing, competition

    Historically, the function of Arctic ecosystems in terms of cycles of nutrients and carbon has led to low levels of primary production and exchanges of energy, water and greenhouse gases have led to low local and regional cooling. Sequestration of carbon from atmospheric CO2, in extensive, cold organic soils and the high albedo from low, snow-covered vegetation have had impacts on regional climate. However, many aspects of the functioning of Arctic ecosystems are sensitive to changes in climate and its impacts on biodiversity. The current Arctic climate results in slow rates of organic matter decomposition. Arctic ecosystems therefore tend to accumulate organic matter and elements despite low inputs. As a result, soil-available elements like nitrogen and phosphorus are key limitations to increases in carbon fixation and further biomass and organic matter accumulation. Climate warming is expected to increase carbon and element turnover, particularly in soils, which may lead to initial losses of elements but eventual, slow recovery. Individual species and species diversity have clear impacts on element inputs and retention in Arctic ecosystems. Effects of increased CO2 and UV-B on whole ecosystems, on the other hand, are likely to be small although effects on plant tissue chemisty, decomposition and nitrogen fixation may become important in the long-term. Cycling of carbon in trace gas form is mainly as CO2 and CH4. Most carbon loss is in the form of CO2, produced by both plants and soil biota. Carbon emissions as methane from wet and moist tundra ecosystems are about 5% of emissions as CO2 and are responsive to warming in the absence of any other changes. Winter processes and vegetation type also affect CH4 emissions as well as exchanges of energy between biosphere and atmosphere. Arctic ecosystems exhibit the largest seasonal changes in energy exchange of any terrestrial ecosystem because of the large changes in albedo from late winter, when snow reflects most

  11. Job mismatching, unequal opportunities and long-term sickness absence in female white-collar workers in Sweden.

    Sandmark, Hélène

    2009-01-01

    To investigate associations between long-term sick-listing and factors at work and in family life. Associations were investigated in a cross-sectional case-referent study. The study base included women in white-collar jobs, aged 30-55 years, living in three urban areas in Sweden between February 2004 and October 2004. A postal questionnaire was constructed with questions on occupational and family circumstances, and sent to 513 randomly selected female white-collar workers, of whom 233 had ongoing sick-leave of 90 days or more. The response rate was 81% (n = 413). Most of the women in this study were in managerial positions. The unadjusted associations showed that sick-listed women with children showed the highest estimates regarding reported long working hours, bullying, high mental strain, low control and low influence at work, and work-family imbalance. In a regression model, the strongest associations were: experiencing too high mental strain in work tasks (odds ratio (OR) = 2.57, 95% confidence interval (CI) = 2.09-3.15) and low control and influence at work (OR=2.17, 95% CI= 1.60-2.94). Sick-listed women reported an overall higher dissatisfaction with their workplace and working life. There seems to be a greater tendency for the sick-listed women in this study to experience low control and too high mental strain at work and to live in traditional family relationships with unequal opportunities. The women who were sick-listed were probably less able to cope with work stress and to find a balance between work and family life.

  12. Long-Term Outcomes of Cognitive–Behavioral Treatments for Posttraumatic Stress Disorder Among Female Rape Survivors

    Resick, Patricia A.; Williams, Lauren F.; Suvak, Michael K.; Monson, Candice M.; Gradus, Jaimie L.

    2012-01-01

    Objective We conducted a long-term follow-up (LTFU) assessment of participants from a randomized controlled trial comparing cognitive processing therapy (CPT) with prolonged exposure (PE) for posttraumatic stress disorder (PTSD). Competing hypotheses for positive outcomes (i.e., additional therapy, medication) were examined. Method Intention-to-treat (ITT) participants were assessed 5–10 years after participating in the study (M = 6.15, SD = 1.22). We attempted to locate the 171 original participants, women with PTSD who had experienced at least one rape. Of 144 participants located, 87.5% were reassessed (N = 126), which constituted 73.7% of the original ITT sample. Self-reported PTSD symptoms were the primary outcome. Clinician-rated PTSD symptoms, comorbid diagnoses, and self-reported depression were secondary outcomes. Results Substantial decreases in symptoms due to treatment (as reported in Resick, Nishith, Weaver, Astin, & Feuer, 2002) were maintained throughout the LTFU period, as evidenced by little change over time from posttreatment through follow-up (effect sizes ranging from pr = .03 to .14). No significant differences emerged during the LTFU between the treatment conditions (Cohen’s d = 0.06–0.29). The ITT examination of diagnostics indicated that 22.2% of CPT and 17.5% of PE participants met the diagnosis for PTSD according to the Clinician-Administered PTSD Scale (Blake et al., 1995) at the LTFU. Maintenance of improvements could not be attributed to further therapy or medications. Conclusions CPT and PE resulted in lasting changes in PTSD and related symptoms over an extended period of time for female rape victims with extensive histories of trauma. PMID:22182261

  13. The immediate and long-term effects of time perspective on Internet gaming disorder.

    Lukavská, Kateřina

    2018-03-01

    Backgrounds and aims This study focuses on the role of time perspective (TP) in Internet gaming disorder (IGD). An inventory-based study on 377 massive multiplayer online role playing game players was conducted, followed by a 3-year-follow-up in which 48 active players from the original sample participated. We proposed that TP factors (negative TP and future positive TP) will influence either the current presence of IGD symptoms or the further development of IGD over time. In other words, the effect of TP is stable. Finally, game usage patterns were analyzed in the sense of changes in playing time and IGD symptoms in gamers after 3 years. Methods To access the variables, two scales were administered through online inventory, the Zimbardo Time Perspective Inventory-short, and Charlton and Danforths' Core Addiction Scale, both in 2012 (N = 377) and 2015 (N = 48). The amount of time that gamers usually spent playing were obtained through self-reports. Results The study's primary presumptions were confirmed. Both negative TP and future positive TP were confirmed as significant predictors of the presence of IGD symptoms, either immediately or in the following 3 years. Data on game usage showed a significant decrease in playing time and IGD symptoms between year 0 and year 3 of the study.

  14. Public Perspectives Toward the Sexual Behavior of an Individual With Dementia Residing in Long-Term Care.

    Yelland, Erin L; Cless, Adam W; Mallory, Allen B; Cless, Jessica D

    2018-06-01

    This study examines public perspectives toward sexual behavior within a heterosexually married couple in which one individual has dementia and resides in a long-term care facility. Respondents included 318 adults in the Southern United States. Paired sample t tests were used to understand how the diagnosis of dementia statistically influenced participants' responses, and a logistic regression model was used to understand how a vignette character's sex and respondent characteristics influenced attitudes. Fifty-eight percent of respondents believed that a sexual relationship should be permitted for an adult with dementia, and t tests revealed that dementia had a statistical effect on participants' responses. Sex of the vignette character was not a predictor of attitudes. Participant's qualitative rationales are offered for additional insight. Respondents who felt that a couple should not engage in a sexual relationship commonly cited consent-related issues as their primary concern. Implications for policy development are discussed.

  16. Accessibility Long Term Perspectives

    Kay Axhausen

    2008-11-01

    Full Text Available Improved accessibility and its correlate lower generalized cost of contact, travel and transport have been sought by dynamic human societies for their economic and social benefits through- out recorded history. The paper will reflect about this process at a number of different spatial and temporal scales based on a conceptual model. Looking back at European history, it will trace the interaction between Christaller's logic of local market areas and the idea of (low contact cost network cities. Focusing on Switzerland since 1950 it will show how network investment changed the relative distribution of population and employment and how this interacted with changes in the preferences of the travelers. Using a recent snapshot of how a substantial sample of Swiss maintain their social networks over often very large areas, it will try to answer the question of what will happen in the future, if the current trend of ever lower costs of contact will persist.

    The purpose of this study was to clarify administrators' perspectives on availability of recommended strategies for end-of-life (EOL) care for cancer patients at long-term care (LTC) facilities in Japan. A cross-sectional survey was conducted with administrators at Japanese LTC facilities. Participants were surveyed about their facilities, reasons for hospitalization of cancer patients, and their perspectives on availability of and strategies for EOL care. The 97 responses were divided into medical facility (n = 24) and non-medical facility (n = 73) groups according to physician availability. The most frequent reasons for hospitalization were a sudden change in patient's condition (49.4%), lack of around-the-clock care (43.0%), and inability to palliate symptoms (41.0%). About 50% of administrators believed their facilities could provide EOL care if supported by palliative care experts. There was no significant difference between facility types (P = 0.635). Most administrators (81.2%) regarded unstable cancer patients as difficult to care for. However, many (68.4%) regarded opioids given orally as easy to administer, but regarded continuous subcutaneous infusion/central venous nutrition as difficult. Almost all administrators believed the most useful strategy was transferring patients to hospitals at the request of patients or family members (96.9%), followed by consultation with palliative care experts (88.5%). Although LTC facilities in Japan currently do not provide adequate EOL care for cancer patients, improvement might be possible with support by palliative care teams. Appropriate models are necessary for achieving a good death for cancer patients. Interventions based on these models are necessary for EOL care for cancer patients in LTC facilities.

  18. The long-term effects of stress and kappa opioid receptor activation on conditioned place aversion in male and female California mice.

    Psychosocial stress leads to the activation of kappa opioid receptors (KORs), which induce dysphoria and facilitate depression-like behaviors. However, less is known about the long-term effects of stress and KORs in females. We examined the long-term effects of social defeat stress on the aversive properties of KOR activation in male and female California mice (Peromyscus californicus) using a conditioned place aversion paradigm. Female California mice naïve to social defeat, formed a place aversion following treatment with 2.5mg/kg of the KOR agonist U50,488, but females exposed to defeat did not form a place aversion to this dose. This supports the finding by others that social defeat weakens the aversive properties of KOR agonists. In contrast, both control and stressed males formed an aversion to 10mg/kg of U50,488. We also examined EGR1 immunoreactivity, an indirect marker of neuronal activity, in the nucleus accumbens (NAc) and found that stress and treatment with 10mg/kg of U50,488 increased EGR1 immunoreactivity in the NAc core in females but reduced activation in males. The effects of stress and U50,488 on EGR1 were specific to the NAc, as we found no differences in the bed nucleus of the stria terminalis. In summary, our data indicate important sex differences in the long-term effects of stress and indicate the need for further study of the molecular mechanisms mediating the behavioral effects of KOR in both males and females.

  20. Long-term disease-free survival in advanced melanomas treated with nitrosoureas: mechanisms and new perspectives.

    Durando, Xavier; Thivat, Emilie; D'Incan, Michel; Sinsard, Anne; Madelmont, Jean-Claude; Chollet, Philippe

    2005-11-15

    Median survival of metastatic malignant melanoma is 6.0 to 7.5 months, with a 5-year survival of approximately 6.0%. Although long-term complete remissions are rare, few reports describe cases after chemotherapy. Fifty-three patients with metastatic melanoma were treated with Cystemustine, a chloroethyl nitrosourea (CENU) (60 or 90 mg/m2). We describe 5 cases, presenting with complete response with long-term disease-free survival of long-term remission of 14, 12, 9, 7 and 6 years after Cystemustine therapy alone. Long-term survival has already been described in literature, but in all cases they have been obtained after chemotherapy associated with or followed by surgery. But despite these noteworthy and encouraging but also rare results, it appears essential to increase Cystemustine efficiency.

    2007-01-01

    We report a female with amyloid arthropathy of the hip joints. She was a 67-year-old woman who had been treated by hemodialysis for 22 years. She had demonstrated a 5-month history of continuous low-grade fever and pain in her left hip and she was finally unable to walk by herself. Findings on X-ray films and MRI of the hip joints suggested avascular necrosis in both femur heads. To palliate symptoms, bipolar surgery on the left hip joint was performed. Pathological examination of bone tissue specimen demonstrated that there was some , β 2 -microglobulin (β 2 -MG)-related amyloid accumulation in the femur head. Based on this clinical experience, we performed MRI screening for amyloid lesions of the hip joints in another 11 asymptomatic female patients undergoing hemodialysis for 20 years or more. Cystic lesions of the hip joints were observed in 8 patients, amyloid arthropathy in 2 patients, and fluid trapped in the joint in 1 patient. Patients with amyloidosis had significantly lower serum β 2 -MG levels than patients without amyloidosis (28.6 mg/L versus 41.4 mg/L; p=0.0339). Our findings show that dialysis-related amyloidosis of the hip joints is one of the potential and significant problems in female patients on long-term hemodialysis therapy. It may be important to screen for this pathological condition in long-term hemodialysis patients. (author)

    2017-01-01

    Full Text Available The present preclinical study was created to determine the therapeutic effects of vitamin D hormone treatment as an adjunctive therapy alone or in a combination with low dose of 17β-estradiol (17β-E2 on anxiety-like behavior in female rats with long-term absence of estrogen. Accordingly, the aim of the current study was to examine the effects of chronic cholecalciferol administration (1.0, 2.5 or 5.0 mg/kg subcutaneously, SC, once daily, for 14 days on the anxiety-like state after long-term ovariectomy in female rats. Twelve weeks postovariectomy, cholecalciferol was administered to ovariectomized (OVX rats and OVX rats treated with 17β-E2 (0.5 µg/rat SC, once daily, for 14 days. Anxiety-like behavior was assessed in the elevated plus maze (EPM and the light/dark test (LDT, and locomotor and grooming activities were tested in the open field test (OFT. Cholecalciferol at two doses of 1.0 and 2.5 mg/kg alone or in combination with 17β-E2 produced anxiolytic-like effects in OVX rats as evidenced in the EPM and the LDT, as well as increased grooming activity in the OFT. Our results indicate that cholecalciferol, at two doses of 1.0 and 2.5 mg/kg, has a profound anxiolytic-like effects in the experimental rat model of long-term estrogen deficiency.

    STUDY DESIGN: Cost-utility evaluation of a randomized, controlled trial with a 4- to 8-year follow-up. OBJECTIVE: To investigate the incremental cost per quality-adjusted-life-year (QALY) when comparing circumferential fusion to posterolateral fusion in a long-term, societal perspective. SUMMARY...... OF BACKGROUND DATA: The cost-effectiveness of circumferential fusion in a long-term perspective is uncertain but nonetheless highly relevant as the ISSLS prize winner 2006 in clinical studies reported the effect of circumferential fusion superior to the effect of posterolateral fusion. A recent trial found...... no significant difference between posterolateral and circumferential fusion reporting cost-effectiveness from a 2-year viewpoint. METHODS: A total of 146 patients were randomized to posterolateral or circumferential fusion and followed 4 to 8 years after surgery. The mean age of the cohort was 46 years (range...

  11. Effect of a Short-Term and Long-Term Melatonin Administration on Mammary Carcinogenesis in Female Sprague-Dawley Rats Influenced by Repeated Psychoemotional Stress

    M. Kassayová

    2007-01-01

    Full Text Available The aim of this study was to evaluate the effect of melatonin (MEL on N-methyl-N-nitrosourea (NMU-induced mammary carcinogenesis in female Sprague-Dawley rats exposed to repeated psychoemotional stress - immobilization in boxes. NMU was applied intraperitoneally in two doses each of 50 mg/kg b.w. between 40 - 50 postnatal days. Melatonin was administered in drinking water at a concentration of 4 μg/ml daily from 15:00 h to 8:00 h. The application was initiated 5 days prior to the fi rst NMU dose and lasted 15 days, i.e. during the promotion phase of tumour development, or long-term until the end of the experiment (week 20. Immobilization (2 h per day began on the third day after the second carcinogen application and lasted for 7 consecutive days. Short-term MEL administration to immobilized animals increased incidence by 22%, decreased tumour frequency per animal by 26% and reduced tumour volume gain (by 21% when compared to the immobilized group without MEL application. Decreased frequency per animal by 28% and more than a 40% decrease in tumour volume gain and cumulative volume were the most pronounced changes in the animals drinking MEL until the end of the experiment. Long-term MEL administration reduced the number and size of mammary tumours more markedly than its short-term administration. Melatonin decreased certain attributes of mammary carcinogenesis in female rats influenced by psychoemotional stress.

  12. Stress responses of adolescent male and female rats exposed repeatedly to cat odor stimuli, and long-term enhancement of adult defensive behaviors.

    Wright, Lisa D; Muir, Katherine E; Perrot, Tara S

    2013-07-01

    In order to characterize the short- and long-term effects of repeated stressor exposure during adolescence, and to compare the effects of using two sources of cat odor as stressor stimuli, male and female adolescent rats (postnatal day (PND) ∼ 38-46) were exposed on five occasions to either a control stimulus, a cloth stimulus containing cat hair/dander, or a section of cat collar previously worn by a cat. Relative to control stimulus exposure, activity was suppressed and defensive behavior enhanced during exposure to either cat odor stimulus (most pervasively in rats exposed to the collar). Only cloth-exposed rats showed elevated levels of corticosterone (CORT), and only after repeated stressor exposure, but interestingly, rats exposed to the collar stimulus during adolescence continued to show increased behavioral indices of anxiety in adulthood. In this group, the time an individual spent in physical contact with a cagemate during the final adolescent exposure was negatively related to stress-induced CORT output in adulthood, which suggests that greater use of social support during adolescent stress may facilitate adult behavioral coping, without necessitating increased CORT release. These findings demonstrate that adolescent male and female rats respond defensively to cat odor stimuli across repeated exposures and that exposure to such stressors during adolescence can augment adult anxiety-like behavior in similar stressful conditions. These findings also suggest a potential role for social behavior during adolescent stressor exposure in mediating long-term outcomes. Copyright © 2012 Wiley Periodicals, Inc.

  13. Long term effects of exposure to automobile exhaust on the pulmonary function of female adults in Tokyo, Japan

    Sekine, K; Shima, M; Nitta, Y; Adachi, M

    2004-01-01

    Aims: To investigate the chronic effects of air pollution caused mainly by automobiles in healthy adult females. Methods: Respiratory symptoms were investigated in 5682 adult females who had lived in the Tokyo metropolitan area for three years or more in 1987; 733 of them were subjected to pulmonary function tests over eight years from 1987 to 1994. The subjects were divided into three groups by the level of air pollution they were exposed to during the study period. The concentrations of nitrogen dioxide and suspended particulate matter were the highest in group 1, and the lowest in group 3. Results: The prevalence rates of respiratory symptoms in group 1 were higher than those in groups 2 and 3, except for wheezing. Multiple logistic regression analysis showed significant differences in persistent phlegm and breathlessness. The subjects selected for the analysis of pulmonary function were 94, 210, and 102 females in groups 1, 2, and 3, respectively. The annual mean change of FEV1 in group 1 was the largest (-0.020 l/y), followed by that in group 2 (-0.015 l/y), and that in group 3 (-0.009 l/y). Testing for trends showed a significant larger decrease of FEV1 with the increase in the level of air pollution. Conclusions: The subjects living in areas with high levels of air pollution showed higher prevalence rates of respiratory symptoms and a larger decrease of FEV1 compared with those living in areas with low levels of air pollution. Since the traffic density is larger in areas with high air pollution, the differences among the groups may reflect the effect of air pollution attributable to particulate matter found in automobile exhaust.

  14. Estradiol attenuates ischemia-induced death of hippocampal neurons and enhances synaptic transmission in aged, long-term hormone-deprived female rats.

    Tomoko Inagaki

    Full Text Available Transient global forebrain ischemia causes selective, delayed death of hippocampal CA1 pyramidal neurons, and the ovarian hormone 17β-estradiol (E2 reduces neuronal loss in young and middle-aged females. The neuroprotective efficacy of E2 after a prolonged period of hormone deprivation is controversial, and few studies examine this issue in aged animals given E2 treatment after induction of ischemia.The present study investigated the neuroprotective effects of E2 administered immediately after global ischemia in aged female rats (15-18 months after 6 months of hormone deprivation. We also used electrophysiological methods to assess whether CA1 synapses in the aging hippocampus remain responsive to E2 after prolonged hormone withdrawal. Animals were ovariohysterectomized and underwent 10 min global ischemia 6 months later. A single dose of E2 (2.25 µg infused intraventricularly after reperfusion significantly increased cell survival, with 45% of CA1 neurons surviving vs 15% in controls. Ischemia also induced moderate loss of CA3/CA4 pyramidal cells. Bath application of 1 nM E2 onto brain slices derived from non-ischemic aged females after 6 months of hormone withdrawal significantly enhanced excitatory transmission at CA1 synapses evoked by Schaffer collateral stimulation, and normal long-term potentiation (LTP was induced. The magnitude of LTP and of E2 enhancement of field excitatory postsynaptic potentials was indistinguishable from that recorded in slices from young rats.The data demonstrate that 1 acute post-ischemic infusion of E2 into the brain ventricles is neuroprotective in aged rats after 6 months of hormone deprivation; and 2 E2 enhances synaptic transmission in CA1 pyramidal neurons of aged long-term hormone deprived females. These findings provide evidence that the aging hippocampus remains responsive to E2 administered either in vivo or in vitro even after prolonged periods of hormone withdrawal.

  15. Working and reference memory across the estrous cycle of rat: a long-term study in gonadally intact females.

    Pompili, Assunta; Tomaz, Carlos; Arnone, Benedetto; Tavares, Maria Clotilde; Gasbarri, Antonella

    2010-11-12

    The results of many studies conducted over the past two decades suggested a role of estrogen on mammal's ability to learn and remember. In the present paper, we analyzed the influence that the endogenous fluctuation of estrogen, naturally present across the different phases of estrous cycle of female rats, can exert over the performance of tasks utilized to assess memory. In particular, we analyzed the performances in an eight arms radial maze task, dependent upon working memory, and in a water maze (WM) task, dependent upon spatial reference memory. The water maze is aversively motivated by the desire to escape onto a safe platform, whereas the radial arm maze (RAM) is motivated by food reward. The difference in reinforcement may affect the speed of learning, the strategy adopted and the necessity for accurate navigation. Therefore, coherent results obtained through the two different tasks can be due to mnemonic factors. The study was conducted during a long period of time, 14 months, utilizing gonadally intact females, without pharmacological and surgical treatments. In order to evaluate the post-acquisition phase we first trained the animals to reach the criterion in performing tasks, and then we submitted them to experimental phase. Our results show that estrogen can have an effect on memory processes, and that this effect may be different in relation to different kinds of memory. In fact, in our study, estrogen selectively improved working memory, but not reference memory, during post-acquisition performance of a RAM task with four baited and four un-baited arms. Moreover, WM performances showed that estrogen have a negative effect on spatial reference memory. (c) 2010 Elsevier B.V. All rights reserved.

    2017-10-24

    Specific macronutrient distribution and training can alter acute and chronic hormone behavior and, subsequently, sport performance. The main aim was to examine relationships between dietary intake and anabolic/catabolic hormone response in elite female volleyball players during a 29-week season. Twenty-two elite female volleyballers (26.4 ± 5.6 years; 178 ± 9 cm; 67.1 ± 7.5 kg) had dietary intake (seven-day dietary recall and food frequency questionnaire), blood concentration of anabolic/catabolic hormones concentration, physical performance, and body composition assessed at four time points: a) T1: baseline/pre-testing; b) T2: eleven weeks after T1; c) T3: ten weeks after T2; and d) T4: eight weeks after T3. Hormones evaluated were: total testosterone (TT), free testosterone (FT) adrenocorticotropic hormone (ACTH), and cortisol (C), along with hormone ratios. Positive correlations were observed between carbohydrate/protein ratio with ΔFT (r = 0.955; p 0.05) in body mass or body mass index at any time point, and the sum of six skinfolds improved (p < 0.05) from T1 (86.5 ± 6.9 mm) to T4 (75.2 ± 5.6 mm) as did muscle mass (T1: 28.9 ± 0.7 kg vsT4: 30.1 ± 0.8 kg). Vertical jump, spike-jump and speed improved (p < 0.05) from T1 to T4. A high carbohydrate/protein ratio was associated with positive changes in anabolism, while high protein and low carbohydrates (CHO) were associated with an attenuated anabolic response.

  17. Long-term effects of conflict-related sexual violence compared with non-sexual war trauma in female World War II survivors: a matched pairs study.

    2014-08-01

    The aim of the study was to compare the long-term effects of conflict-related sexual violence experienced at the end of World War II (WWII) with non-sexual WWII trauma (e.g., being exposed to shell shock or physical violence). A total of 27 elderly wartime rape survivors were compared to age- and gender-matched control subjects who were drawn from a larger sample of subjects over 70 years of age who had experienced WWII-related trauma. A modified version of the Posttraumatic Diagnostic Scale was used to assess trauma characteristics and posttraumatic stress disorder (PTSD) symptoms and the Brief Symptom Inventory-18 was used to assess current psychopathology. Additionally, measures of posttraumatic growth (Posttraumatic Growth Inventory) and social acknowledgement as a trauma survivor (Social Acknowledgement Questionnaire) were used to assess two mediating variables in post-trauma conditions of rape victims. Women exposed to conflict-related sexual violence reported greater severity of PTSD-related avoidance and hyperarousal symptoms, as well as anxiety, compared with female long-term survivors of non-sexual WWII trauma. The vast majority (80.9 %) of these women also reported severe sexual problems during their lifetimes relative to 19.0 % of women who experienced non-sexual war trauma. Women exposed to conflict-related sexual violence also reported greater posttraumatic growth, but less social acknowledgement as trauma survivors, compared to survivors of non-sexual war trauma. The results were consistent with emerging neurobiological research, which suggests that different traumas may be differentially associated with long-term posttraumatic sequelae in sexual assault survivors than in other survivor groups and highlights the need to treat (or better prevent) deleterious effects of conflict-related sexual violence in current worldwide crisis zones.

  18. Living Well With a Long-Term Condition: Service Users' Perspectives of a Self-Management Intervention.

    Stenberg, Nicola; Furness, Penny J

    2017-03-01

    The outcomes of self-management interventions are commonly assessed using quantitative measurement tools, and few studies ask people with long-term conditions to explain, in their own words, what aspects of the intervention they valued. In this Grounded Theory study, a Health Trainers service in the north of England was evaluated based on interviews with eight service-users. Open, focused, and theoretical coding led to the development of a preliminary model explaining participants' experiences and perceived impact of the service. The model reflects the findings that living well with a long-term condition encompassed social connectedness, changed identities, acceptance, and self-care. Health trainers performed four related roles that were perceived to contribute to these outcomes: conceptualizer, connector, coach, and champion. The evaluation contributes a grounded theoretical understanding of a personalized self-management intervention that emphasizes the benefits of a holistic approach to enable cognitive, behavioral, emotional, and social adjustments.

  19. Reforming Management of Behavior Symptoms and Psychiatric Conditions in Long-Term Care Facilities: A Different Perspective.

    Levenson, Steven A; Desai, Abhilash K

    2017-04-01

    Despite much attention including national initiatives, concerns remain about the approaches to managing behavior symptoms and psychiatric conditions across all settings, including in long-term care settings such as nursing homes and assisted living facilities. One key reason why problems persist is because most efforts to "reform" and "correct" the situation have failed to explore or address root causes and instead have promoted inadequate piecemeal "solutions." Further improvement requires jumping off the bandwagon and rethinking the entire issue, including recognizing and applying key concepts of clinical reasoning and the care delivery process to every situation. The huge negative impact of cognitive biases and rote approaches on related clinical problem solving and decision making and patient outcomes also must be addressed.

    The immediate and short-term consequences of adult HIV for affected children are well documented. Little research has examined the long-term implications of childhood adversity stemming from caregiver HIV infection. Through overviews provided by experts in the field, together with an iterative process of consultation and refinement, we have extracted insights from the broader field of child development of relevance to predicting the long-term consequences to children affected by HIV and AIDS. We focus on what is known about the impact of adversities similar to those experienced by HIV-affected children, and for which there is longitudinal evidence. Cautioning that findings are not directly transferable across children or contexts, we examine findings from the study of parental death, divorce, poor parental mental health, institutionalization, undernutrition, and exposure to violence. Regardless of the type of adversity, the majority of children manifest resilience and do not experience any long-term negative consequences. However, a significant minority do and these children experience not one, but multiple problems, which frequently endure over time in the absence of support and opportunities for recovery. As a result, they are highly likely to suffer numerous and enduring impacts. These insights suggest a new strategic approach to interventions for children affected by HIV and AIDS, one that effectively combines a universal lattice of protection with intensive intervention targeted to selected children and families.

    Full Text Available The precise role of neural plasticity under pathological conditions remains not well understood. It appears to be well accepted, however, that changes in the ability of neurons to express plasticity accompany neurological diseases. Here, we discuss recent experimental evidence, which suggests that synaptic plasticity induced by a pathological stimulus, i.e., ischemic long-term-potentiation (iLTP of excitatory synapses, could play an important role for post-stroke recovery by influencing the post-lesional reorganization of surviving neuronal networks.

  2. Negotiated risk and resident autonomy: Frontline care staff perspectives on culture change in long term care in Nova Scotia, Canada.

    Roberts, Emily

    2016-08-12

    Regulating risk, freedom of action, and autonomy in decision making are problems shared by both caregivers and residents in long term care settings, and may become the subject of tension and constant negotiation. This study focuses on long term care staff and management perceptions of day to day life in a care community which has gone through a culture change transition, where small residentially scaled households replace large instutional models of care. In each household, the setting is considered to be home for the 8-12 residents, creating a major shift of roles for the caregivers; they are, in essence, coming into a home rather than institutional environment as a place of work. This potentially changes the dynamics of both patterns of work for caregivers and patterns of daily living for residents. Participant observations and care staff interviews. Several key themes emrged which include: teamwork; the culture of care; regulating risk; the physical environment and care staff empowerment. An unexpected outcome was the consensus among care staff that it is they who feel at home while working in the care households, leading to empowerment in their work roles and a deeper understanding of the importance of their role in the lives of the residents.

  4. Long-Term Perspectives of Family Quality of Life Following Music Therapy With Young Children on the Autism Spectrum: A Phenomenological Study.

    Thompson, Grace A

    2018-01-13

    Parents of children on the autism spectrum have consistently reported feeling uncertain in their parenting role, and desire more practical advice from service providers about how to support their child in the home. There is growing recognition of the need for interventions to provide support to the family as well as fostering child development outcomes. This study explores mothers' follow-up perspectives of family-centered music therapy (FCMT) four years after participating in a 16-week home-based program, and therefore provides a unique long-term viewpoint on FCMT outcomes. Eight mothers who previously participated in FCMT sessions with their young children on the autism spectrum were interviewed to explore their perception of any long-term outcomes. A descriptive phenomenological analysis revealed five global themes, including: improvement in mothers' confidence to engage their child; rare opportunities for mutual mother-child enjoyment; improved child social communication and quality of life; mothers' new understanding of the child's interests and strengths; and more opportunities for continuing the child's interest in music. Mothers perceived long-term benefits to social relationships within the family, leading to perceived enrichment in child and family quality of life following music therapy sessions. © American Music Therapy Association 2017.

  5. Explaining the success or failure of quality improvement initiatives in long-term care organizations from a dynamic perspective.

    Etheridge, Francis; Couturier, Yves; Denis, Jean-Louis; Tremblay, Lucie; Tannenbaum, Cara

    2014-09-01

    The purpose of this study was to better understand why change initiatives succeed or fail in long-term care organizations. Four case studies from Québec, Canada were contrasted retrospectively. A constipation and restraints program succeeded, while an incontinence and falls program failed. Successful programs were distinguished by the use of a change strategy that combined "let-it happen," "help-it happen," and "make-it happen" interventions to create senses of urgency, solidarity, intensity, and accumulation. These four active ingredients of the successful change strategies propelled their respective change processes forward to completion. This paper provides concrete examples of successful and unsuccessful combinations of "let-it happen," "help-it happen," and "make-it happen" change management interventions. Change managers (CM) can draw upon these examples to best tailor and energize change management strategies in their own organizations. © The Author(s) 2013.

    2009-03-01

    ASSISTIVE TECHNOLOGIES ARE RELATIVELY novel tools for research and daily care in long-term care (LTC) facilities that are faced with the burgeoning of the older adult population and dwindling staffing resources. The degree to which stakeholders in LTC facilities are receptive to the use of these technologies is poorly understood. Eighteen semi-structured focus groups and one interview were conducted with relevant groups of stakeholders at seven LTC facilities in southwestern Pennsylvania. Common themes identified across all focus groups centered on concerns for privacy, autonomy, cost, and safety associated with implementation of novel technologies. The relative importance of each theme varied by stakeholder group as well as the perceived severity of cognitive and/or physical disability. Our findings suggest that ethical issues are critical to acceptance of novel technologies by their end users, and that stakeholder groups are interdependent and require shared communication about the acceptance of these emerging technologies.

  7. Evaluating the Impact of an Active Labour Market Policy on Employment: Short- and Long-Term Perspectives

    José M. Cansino

    2018-04-01

    Full Text Available The Labour Market Insertion Contract was an Active Labour Market Policy introduced in Spain. It was aimed at individuals who had difficulties entering the labour market, and it was introduced with the purpose of reducing the rate of unemployment. This article provides an estimation of the average impact that this contract had on the employability of individuals in the short and long term. A microeconomic analysis was carried out based on causal statistical inference by using propensity score matching and kernel and radial estimators. Data was taken from the most comprehensive database available, which is the Continuous Sample of Work Histories. Results are consistent with literature reports and show that the employability of participants was inferior to that of individuals with similar, temporary-type contracts. This research contributes to the literature by evaluating whether there was empirical evidence to support the political decision to revoke or replace this kind of direct employment programme.

    Full Text Available Abstract Background Sick leave rates in Sweden have been significant since the end of the 1990s. In this paper we focus on individual female white-collar workers and explore various factors and setting-based sources of ill health in working life and in private life, in order to understand impaired work ability, leading ultimately to long-term sick leave. Methods A qualitative methodology was chosen, and thematic, open-ended interviews were carried out with 16 women. The interviewees were strategically selected from a cohort of 300 women in full-time white-collar jobs in high-level positions, living in three urban areas in Sweden, and on long-term sick leave ≥90 days. A qualitative content analysis was carried out. Results The informants in the study were generally well educated, but a few had surprisingly little formal education considering their salary level and position on the labour market. The women were in professional positions more commonly held by men, either as specialists with some degree of managerial role or as executives with managerial responsibilities. Both external and internal stressors were identified. The analysis indicated that being in these gender-typed jobs could have induced sex discrimination and role conflicts. The women expressed strong agreement regarding success in working life, but emphasised the lack of competence matching in their present jobs. They also lacked the sense of having a rewarding job, saw leadership as weak, and disliked their present workplace and colleagues. Impaired health may have hindered them from changing jobs; conversely, their locked-in positions could have resulted in deterioration in their health status. The women displayed personal overcommitment, both at work and in private life, and had difficulties in setting limits.

  10. Long Term Physiologic and Behavioural Effects of Housing Density and Environmental Resource Provision for Adult Male and Female Sprague Dawley Rats

    Christopher J. Pinelli

    2017-06-01

    Full Text Available There is considerable interest in refining laboratory rodent environments to promote animal well-being, as well as research reproducibility. Few studies have evaluated the long term impact of enhancing rodent environments with resources and additional cagemates. To that end, male and female Sprague Dawley (SD rats were housed singly (n = 8/sex, in pairs (n = 16/sex, or in groups of four (n = 16/sex for five months. Single and paired rats were housed in standard cages with a nylon chew toy, while group-housed rats were kept in double-wide cages with two PVC shelters and a nylon chew toy and were provided with food enrichment three times weekly. Animal behaviour, tests of anxiety (open field, elevated plus maze, and thermal nociception, and aspects of animal physiology (fecal corticoid levels, body weight, weekly food consumption, organ weights, and cerebral stress signaling peptide and receptor mRNA levels were measured. Significant differences were noted, primarily in behavioural data, with sustained positive social interactions and engagement with environmental resources noted throughout the study. These results suggest that modest enhancements in the environment of both male and female SD rats may be beneficial to their well-being, while introducing minimal variation in other aspects of behavioural or physiologic responses.

    Full Text Available Lauren L Levy, Jason J Emer Department of Dermatology, Mount Sinai School of Medicine, New York, NY, USA Abstract: Hair loss is a commonly encountered problem in clinical practice, with men presenting with a distinctive pattern involving hairline recession and vertex balding (Norwood-Hamilton classification and women exhibiting diffuse hair thinning over the crown (increased part width and sparing of the frontal hairline (Ludwig classification. Female pattern hair loss has a strikingly overwhelming psychological effect; thus, successful treatments are necessary. Difficulty lies in successful treatment interventions, as only two medications – minoxidil and finasteride – are approved for the treatment of androgenetic alopecia, and these medications offer mediocre results, lack of a permanent cure, and potential complications. Hair transplantation is the only current successful permanent option, and it requires surgical procedures. Several other medical options, such as antiandrogens (eg, spironolactone, oral contraceptives, cyproterone, flutamide, dutasteride, prostaglandin analogs (eg, bimatoprost, latanoprost, and ketoconazole are reported to be beneficial. Laser and light therapies have also become popular despite the lack of a profound benefit. Management of expectations is crucial, and the aim of therapy, given the current therapeutic options, is to slow or stop disease progression with contentment despite patient expectations of permanent hair regrowth. This article reviews current perspectives on therapeutic options for female pattern hair loss.

  13. Evolutionist approach of upstream activities competitiveness of the petroleum industry in a long term perspective; Approche evolutionniste de la competitivite des activites amont de la filiere petroliere dans une perspective de long terme

    Dos Santos, E M

    1997-01-24

    The purpose of this work is to analyze the concept of competitiveness of companies and nations in the upstream sector of the international oil industry, trying to identify the possibilities of future development of this sector as well as the interactions that may exist between different actors such as governments, consumers and oil companies to boost or re-launch the competitive position of their enterprises and countries in the international context of the industry. In order to attain that, we analyze the developments of the most important economic attributes that characterize the oil activity as well as its most crucial political aspects. We develop a model of `oil competition` and a definition of `oil competitiveness` that take clearly into consideration both the differences between various oil actors and the dynamic aspects linked to the evolution of the oil industry. We do so by constructing an evolutionist model of competition and competitiveness. This approach emulates a `biological process` where firms and the economic environment interact with each other within a process similar to `natural selection` with the survival of the fittest. This evolutionist model adopts some analytical instruments established by Michael Porter, from the University of Harvard, to interpret the changes and the dissimilarities of behavior of various oil actors as well as to explain their respective role in the new oil world that is being organized. Thus, we introduce the notions of `dominant form of competition` and `generic strategy of enterprises`. Then, we use our methodology to analyze the past of the oil industry (the stability and the instability). We conclude this work by discussing about the future evolution of the oil activities in the context of a new long term cycle of investment for the sector. (author).

  14. Complications Associated with Long-Term Disposition of Newly-Generated Transuranic Waste: A National Laboratory Perspective

    Orchard, B.J.; Harvego, L.A.; Carlson, T.L.; Grant, R.P.

    2009-01-01

    The Idaho National Laboratory (INL) is a multipurpose national laboratory delivering specialized science and engineering solutions for the U.S. Department of Energy (DOE). Sponsorship of INL was formally transferred to the DOE Office of Nuclear Energy, Science and Technology (NE) by Secretary Spencer Abraham in July 2002. The move to NE, and designation as the DOE lead nuclear energy laboratory for reactor technology, supports the nation's expanding nuclear energy initiatives, placing INL at the center of work to develop advanced Generation IV nuclear energy systems; nuclear energy/hydrogen coproduction technology; advanced nuclear energy fuel cycle technologies; and providing national security answers to national infrastructure needs. As a result of the Laboratory's NE mission, INL generates both contact-handled and remote-handled transuranic (TRU) waste from ongoing operations. Generation rates are relatively small and fluctuate based on specific programs and project activities being conducted; however, the Laboratory will continue to generate TRU waste well into the future in association with the NE mission. Currently, plans and capabilities are being established to transfer INL's contact-handled TRU waste to the Advanced Mixed Waste Treatment Plant (AMWTP) for certification and disposal to the Waste Isolation Pilot Plant (WIPP). Remote-handled TRU waste is currently placed in storage at the Materials and Fuels Complex (MFC). In an effort to minimize future liabilities associated with the INL NE mission, INL is evaluating and assessing options for the management and disposition of all its TRU waste on a real-time basis at time of generation. This paper summarizes near-term activities to minimize future re handling of INL's TRU waste, as well as, potential complications associated with the long-term disposition of newly-generated TRU waste. Potential complications impacting the disposition of INL newly-generated TRU waste include, but are not limited to: (1

  15. Straw-to-soil or straw-to-energy? An optimal trade off in a long term sustainability perspective

    Monteleone, Massimo; Cammerino, Anna Rita Bernadette; Garofalo, Pasquale; Delivand, Mitra Kami

    2015-01-01

    Highlights: • Energy balance and GHG savings of a straw-to-electricity value chain were determined. • An “expanded” LCA was performed, from farm field to electricity delivery. • Both direct and indirect factors of land use change have been considered in the analysis. • No-tillage and crop rotation significantly improved the system performance. • A win–win, sustainable solution for the energy use of straw has been identified. - Abstract: This study examined some management strategies of wheat cultivation system and its sustainability in using straw as an energy feedstock. According to the EU regulatory framework on biofuels, no GHG emissions should be assigned to straws when they are used for energy. Given this relevance in the current energy policy, it is advisable to include all possible marginal effects related to land use, resource utilization and management changes in the comparison of different biomass options. Coherently, an expanded life cycle assessment (LCA) was applied to include the upstream cultivation phase and to make a comparison between “straw to soil” and “straw to energy”. Different crop management conditions in Southern Italy were simulated, by using the CropSyst model, to estimate the long-term soil organic carbon and annual N 2 O soil emissions. Three wheat cropping systems were considered: the conventional single wheat system without straw removal (W0) and with partial straw removal (W1), together with a no-tillage “wheat-wheat-herbage” rotation system with partial straw removal (W2). The results of the simulations were integrated in the LCA to compare fossil energy consumption and greenhouse gas (GHG) emissions of straw-to-electricity with respect to the fossil-based electricity system. The “improved” rotational wheat cropping system (W2) gave the best performance in terms both of GHG savings and fossil displacement, thus stressing that straw use for energy generation in parallel with the optimization of the

  16. Innovative Perspective: Gadolinium-Free Magnetic Resonance Imaging in Long-Term Follow-Up after Kidney Transplantation

    Mick J. M. van Eijs

    2017-05-01

    Full Text Available Since the mid-1980s magnetic resonance imaging (MRI has been investigated as a non- or minimally invasive tool to probe kidney allograft function. Despite this long-standing interest, MRI still plays a subordinate role in daily practice of transplantation nephrology. With the introduction of new functional MRI techniques, administration of exogenous gadolinium-based contrast agents has often become unnecessary and true non-invasive assessment of allograft function has become possible. This raises the question why application of MRI in the follow-up of kidney transplantation remains restricted, despite promising results. Current literature on kidney allograft MRI is mainly focused on assessment of (sub acute kidney injury after transplantation. The aim of this review is to survey whether MRI can provide valuable diagnostic information beyond 1 year after kidney transplantation from a mechanistic point of view. The driving force behind chronic allograft nephropathy is believed to be chronic hypoxia. Based on this, techniques that visualize kidney perfusion and oxygenation, scarring, and parenchymal inflammation deserve special interest. We propose that functional MRI mechanistically provides tools for diagnostic work-up in long-term follow-up of kidney allografts.

  17. The long-term effects of parental divorce on the mental health of young adults: a developmental perspective.

    Chase-Lansdale, P L; Cherlin, A J; Kiernan, K E

    1995-12-01

    The effects of parental divorce during childhood and adolescence on the mental health of young adults (age 23) were examined, using the National Child Development Study (NCDS), a longitudinal, multimethod, nationally representative survey of all children born in Great Britain during 1 week in 1958 (N = 17,414). Children were assessed at birth and subsequently followed up at ages 7, 11, 16, and 23 by means of maternal and child interviews, and by psychological, school, and medical assessments. Parental divorce had a moderate, long-term negative impact on adult mental health, as measured by the Malaise Inventory total score, and controlling for economic status, children's emotional problems, and school performance preceding marital dissolution. The likelihood of scoring above the clinical cutoff of the Malaise Inventory rose from 8% to 11% due to parental divorce. This indicated that the relative risk of serious emotional disorders increased in the aftermath of divorce, but that the large majority of individuals did not exhibit such risks. Path analyses revealed that the negative effects of divorce on adult mental health operated indirectly through higher emotional problems and lower levels of school achievement and family economic status at age 16. Results related to timing of divorce, remarriage, and interactions between age 7 emotional problems and divorce, and between age 7 emotional problems and child gender, are also discussed.

  18. Barriers and enablers to returning to work from long-term sickness absence: Part I-A quantitative perspective.

    Board, Belinda J; Brown, Jennifer

    2011-04-01

    Long-term sickness absence (LTSA) in the United Kingdom labor market has become a major health issue in recent years. In contrast to short-term sickness absence, rates for LTSA have been on the increase. This paper, part 1 of a two-part paper, identifies individual domain barriers to returning to work (RTW) from LTSA across the work disability timeline in the UK labor market. This is a retrospective cohort study of 6,246 workers from an occupationally diverse Police Force within the UK using a large administrative database. A series of chi-squared analyses were conducted to analyze the between and within group associations. Next, multiple logistic regression analyses using the Enter method were performed to develop a predictive model for RTW and Absence Phase. Findings substantiated the presence of individual domain barriers to RTW and predictors of RTW outcome and established the absence phase specificity of a number of risk factors of prolonged work disability. In particular, injury/illness especially mental ill health (MIH), physical job demands, sex, and number of episodes of LTSA are significant individual domain barriers to RTW and represent important risk factors for prolonged work disability. Duration of work disability is associated with medical diagnosis, especially MIH, physical job demands, sex, and number of LTSA episodes. Findings also support the importance of using the outcome measure of absence phase of risk factors in addition to RTW outcome. Copyright © 2010 Wiley-Liss, Inc.

  19. China's Building Energy Use: A Long-Term Perspective based on a Detailed Assessment

    Eom, Jiyong; Clarke, Leon E.; Kim, Son H.; Kyle, G. Page; Patel, Pralit L.

    2012-01-13

    We present here a detailed, service-based model of China's building energy use, nested in the GCAM (Global Change Assessment Model) integrated assessment framework. Using the model, we explore long-term pathways of China's building energy use and identify opportunities of reducing greenhouse gas emissions. The inclusion of a structural model of building energy demands within an integrated assessment framework represents a major methodological advance. It allows for a structural understanding of the drivers of building energy consumption while simultaneously considering the other human and natural system interactions that influence changes in the global energy system and climate. We also explore a range of different scenarios to gain insights into how China's building sector might evolve and what the implications might be for improved building energy technology and carbon policies. The analysis suggests that China's building energy growth will not wane anytime soon, although technology improvement will put downward pressure on this growth. Also, regardless of the scenarios represented, the growth will involve the continued, rapid electrification of the buildings sector throughout the century, and this transition will be accelerated by the implementation of carbon policy.

  1. Changing perspectives in pre-existing diabetes and obesity in pregnancy: maternal and infant short- and long-term outcomes.

    Barbour, Linda A

    2014-08-01

    Climbing obesity rates in women have propelled the increasing prevalence of type 2 diabetes mellitus (T2DM) in pregnancy, and an increasing number of women with type 1 diabetes mellitus (T1DM) are also affected by obesity. Increasing recognition that an intrauterine environment characterized by obesity, insulin resistance, nutrient excess, and diabetes may be fueling the obesity epidemic in children has created enormous pressure to re-examine the conventional wisdom of our current approaches. Compelling data in pregnancies complicated by diabetes, in particular those accompanied by insulin resistance and obesity, support a fetal programming effect resulting in increased susceptibility to metabolic disease for the offspring later in life. Recent data also underscore the contribution of obesity, lipids, and lesser degrees of hyperglycemia on fetal fat accretion, challenging the wisdom of current gestational weight gain recommendations with and without diabetes. The risks of adverse pregnancy outcomes in T2DM are at least as high as in T1DM and there remains controversy about the ideal glucose treatment targets, the benefit of different insulin analogues, and the role of continuous glucose monitoring in T1DM and T2DM. It has become unmistakably evident that achieving optimal outcomes in mothers with diabetes is clearly impacted by ideal glycemic control but goes far beyond it. The intrauterine metabolic environment seems to have long-term implications on the future health of the offspring so that the effectiveness of our current approaches can no longer be simply measured by whether or not maternal glucose values are at goal.

    Objective(s): Weight gain and metabolic disturbances such as dyslipidemia, are frequent side effects of second-generation antipsychotics, including olanzapine. This study examined the metabolic effects of chronic olanzapine exposure. In addition, we investigated the hepatic fatty acid effects of olanzapine in female C57BL/6J mice fed a normal diet. Materials and Methods: Female C57BL/6J mice orally received olanzapine or normal saline for 7 weeks. The effects of long-term olanzapine exposure on body weight changes, food efficiency, blood glucose, triglyceride (TG), insulin, and leptin levels were observed. Hepatic TG and abdominal fat mass were investigated, and fat cell morphology was analyzed through histopathological methods. The levels of protein markers of fatty acid regulation in the liver, namely fatty acid synthase (FAS) and stearoyl-CoA desaturase-1 (SCD-1), were measured. Results: Olanzapine treatment increased the food intake of the mice as well as their body weight. Biochemical analyses showed that olanzapine increased blood TG, insulin, leptin, and hepatic TG. The olanzapine group exhibited increased abdominal fat mass and fat cell enlargement in abdominal fat tissue. Western blotting of the mouse liver revealed significantly higher (1.6-fold) levels of SCD-1 in the olanzapine group relative to the control group; by contrast, FAS levels in the two groups did not differ significantly. Conclusion: Enhanced lipogenesis triggered by increased hepatic SCD-1 activity might be a probable peripheral mechanism of olanzapine-induced dyslipidemia. Some adverse metabolic effects of olanzapine may be related to the disturbance of lipid homeostasis in the liver. PMID:29922430

    The aim of this study is to identify physiological responses of male and female rats to either a short- or long-term administration of two doses of Maca (Lepidium peruvianum) and observe relationships which may exist between groups of hormones and effects mediated by them. The effect of pre-gelatinized (extruded) organic Maca powder (Maca-GO) was studied on Sprague-Dowley male and female rats (1:1 ratio) receiving two dietary levels of Maca-GO (0.75 g/kg and 7.5 g/kg body weight) and assessed against control during 28 and 90 day laboratory trials on 30 and 60 rats respectively. Blood morphology, biochemistry (hormones, lipids and minerals) and histology of internal organs were determined. Homogenates of skeletal muscles and bones of rats were also analyzed. Maca-GO has low toxicity (LD=7.5 g/kg) and appears to be safe for short-term and extended use as dietary supplement or as a component of functional dietary and therapeutic preparations. There were different responses of male and female rats to different levels of Maca-GO administered during a short- and a longer-term periodl. When administered at higher dose for extended period of time (90 days), Maca-GO acted as a toner of hormonal processes in adult female rats at increased progesterone and a steady estradiol level, without affecting levels of blood FSH, LH and TSH. Obtained results justify further clinical research on use of Maca-GO in sportsmen, physically-active people of both sexes and peri-menopausal women to clarify mechanisms underlaying physiological mode of action of Maca-GO validaet in clinical study on humans. Substantial decrease in blood cortisol levels in a short- and longer-term trial and simultaneous tendency to lower blood ACTH, may indicate antidepressive effect of Maca-GO, which together with reduction in body weight, lowering triglycerides in blood plasma and increasing calcium and phosphorus deposition in bone and muscle tissues is worthy consideration in potential application to women at

    Full Text Available Background: This study determines whether -week high-fat diet (HFD consumption alters insulin sensitivity, kidney function, and blood pressure (BP in female rats when compared with standard rodent diet (ND intake in gender- and age-matched rats. Methods: The present study investigates, in female Wistar HanUnib rats, the effect of long-term high-fat fed group (HFD compared with standard chow on BP by an indirect tail-cuff method using an electrosphygmomanometer, insulin and glucose function, and kidney function by creatinine and lithium clearances. Results: The current study shows glucose tolerance impairment, as demonstrated by increased fasting blood glucose (ND: ±2.8 vs. HFD: 87±3.8 mg/dL associated with reduced insulin secretion (ND: 0.58±0.07 vs. HFD: 0.40±0.03 ng/mL in 8-week female HFD-treated rats. The incremental area under the curve (AUC, ND: 1,4558.0±536.0 vs. HFD: 1,6507.8±661.9, homeostasis model assessment of insulin resistance (HOMA-IR index, and the first-order rate constant for the disappearance of glucose (Kitt were significantly enhanced in 8-week HFD-treated rats compared with age-matched ND group (respectively, P=0.03, P=0.002, and P<0.0001. The current study also shows a significantly higher systolic BP measured in 5 and 8 weeks posttreatment in HFD (5-week HFD-treated: 155.25±10.54 mmHg and 8-week HFD-treated: 165±5.8 mmHg (P=0.0001, when compared to BP values in 5-week ND, 137±4.24 mmHg and 8-week ND, 131.75±5.8 mmHg age-matched group. Otherwise, the glomerular filtration rate and renal sodium handling evaluated by FENa, FEPNa and FEPPNa, were unchanged in both groups. Conclusion: We may conclude that 8-week female HFD-fed rats compared with ND group stimulate harmful effects, such as BP rise and peripheral glucose intolerance. The increased BP occurs through insulin resistance and supposedly decreased vasodilatation response without any change on renal function.

  7. Paleoecological studies on variability in marine fish populations: A long-term perspective on the impacts of climatic change on marine ecosystems

    2010-02-01

    The use of historical fishing records to understand relationships between climatic change and fish abundance is limited by the relatively short duration of these records, and complications due to the strong influence of human activity in addition to climatic change. Sedimentary records containing scales, bones or geochemical proxies of variability in fish populations provide unique insights on long-term ecosystem dynamics and relationships with climatic change. Available records from Holocene sediments are summarized and synthesized. The records are from several widespread locations near or along the continental margins of the South Atlantic and Pacific oceans, including Alaska, USA (Pacific salmon), Saanich and Effingham Inlets, British Columbia, Canada (pelagic fish), Santa Barbara Basin, California, USA (Northern anchovies and Pacific sardines), Gulf of California, Mexico (Pacific sardines, Northern anchovies and Pacific hake), Peru upwelling system (sardines, anchovies and hake), and Benguela Current System, South Africa (sardines, anchovies and hake). These records demonstrate that fish population sizes are not constant, and varied significantly over a range of time scales prior to the advent of large-scale commercial fishing. In addition to the decadal-scale variability commonly observed in historical records, the long-term records reveal substantial variability over centennial and millennial time scales. Shifts in abundance are often, but not always, correlated with regional and/or global climatic changes. The long-term perspective reveals different patterns of variability in fish populations, as well as fish-climate relationships, than suggested by analysis of historical records. Many records suggest prominent changes in fish abundance at ca. 1000-1200 AD, during the Little Ice Age, and during the transition at the end of the Little Ice Age in the 19th century that may be correlative, and that were likely driven by major hemispheric or global

  8. The Long-term Impact of Early Life Pain On Adult Responses to Anxiety and Stress: Historical Perspectives and Empirical Evidence

    Victoria, Nicole C.; Murphy, Anne Z.

    2016-01-01

    Approximately 1 in 6 infants are born prematurely each year. Typically, these infants spend 25 days in the Neonatal Intensive Care Unit (NICU) where they experience 10–18 painful and inflammatory procedures each day. Remarkably, pre-emptive analgesics and/or anesthesia are administered less than 25% of the time. Unalleviated pain during the perinatal period is associated with permanent decreases in pain sensitivity, blunted cortisol responses and high rates of neuropsychiatric disorders. To date, the mechanism(s) by which these long-term changes in stress and pain behavior occur, and whether such alterations can be prevented by appropriate analgesia at the time of insult, remains unclear. Work in our lab using a rodent model of early life pain suggests that inflammatory pain experienced on the day of birth blunts adult responses to stress- and pain-provoking stimuli, and dysregulates the hypothalamic pituitary adrenal (HPA) axis in part through a permanent upregulation in central endogenous opioid tone. This review focuses on the long-term impact of neonatal inflammatory pain on adult anxiety- and stress-related responses, and underlying neuroanatomical changes in the context of endogenous pain control and the HPA axis. These two systems are in a state of exaggerated developmental plasticity early in postnatal life, and work in concert to respond to noxious or aversive stimuli. We present empirical evidence from animal and clinical studies, and discuss historical perspectives underlying the lack of analgesia/anesthetic use for early life pain in the modern NICU.

  9. Circadian activity rhythms and voluntary ethanol intake in male and female ethanol-preferring rats: effects of long-term ethanol access.

    Rosenwasser, Alan M; McCulley, Walter D; Fecteau, Matthew

    2014-11-01

    Chronic alcohol (ethanol) intake alters fundamental properties of the circadian clock. While previous studies have reported significant alterations in free-running circadian period during chronic ethanol access, these effects are typically subtle and appear to require high levels of intake. In the present study we examined the effects of long-term voluntary ethanol intake on ethanol consumption and free-running circadian period in male and female, selectively bred ethanol-preferring P and HAD2 rats. In light of previous reports that intermittent access can result in escalated ethanol intake, an initial 2-week water-only baseline was followed by either continuous or intermittent ethanol access (i.e., alternating 15-day epochs of ethanol access and ethanol deprivation) in separate groups of rats. Thus, animals were exposed to either 135 days of continuous ethanol access or to five 15-day access periods alternating with four 15-day periods of ethanol deprivation. Animals were maintained individually in running-wheel cages under continuous darkness throughout the experiment to allow monitoring of free-running activity and drinking rhythms, and 10% (v/v) ethanol and plain water were available continuously via separate drinking tubes during ethanol access. While there were no initial sex differences in ethanol drinking, ethanol preference increased progressively in male P and HAD2 rats under both continuous and intermittent-access conditions, and eventually exceeded that seen in females. Free-running period shortened during the initial ethanol-access epoch in all groups, but the persistence of this effect showed complex dependence on sex, breeding line, and ethanol-access schedule. Finally, while females of both breeding lines displayed higher levels of locomotor activity than males, there was little evidence for modulation of activity level by ethanol access. These results are consistent with previous findings that chronic ethanol intake alters free-running circadian

  11. Living and managing with the long-term implications of neonatal chronic lung disease: The experiences and perspectives of children and their parents.

    Bray, Lucy; Shaw, Nigel J; Snodin, Jill

    2015-01-01

    The purpose of the study was to investigate children's perspectives of living with chronic lung disease (CLD) and their parents' long-term experiences of caring for them. CLD caused by prematurity of birth is associated with continuing respiratory, neuro-developmental and psychosocial issues. 10 children (6-15 years old) with CLD and 12 parents were involved in semi-structured qualitative interviews. Data were analyzed using thematic analysis. CLD was described as 'getting easier over time' and that you 'learnt to live with it.' Expertise was acquired in controlling symptoms and recognizing the onset of illness, despite expressed uncertainty of the nature of the condition. Children experienced difficulties engaging in peer activities and encountered cases of teasing and isolation at school. CLD was reported as becoming easier over time to live with. Despite this, children experienced challenges engaging in peer activities and families described difficulties interacting with health and education services. Copyright © 2015 Elsevier Inc.

    2009-09-01

    Full Text Available This article highlights a study which explored youths’ perspectives on their long-term involvement at Adventure Central, a comprehensive 4-H youth development program based at an urban park facility. We conducted four focus groups with 16 youth between the ages of 12 and 16 who had participated in the program between three and seven years. The youth experienced a wide range of opportunities including nature-related activities, jobs at park facilities, and travel. They spoke positively of their experiences and described how they benefited from their participation. Novelty, challenge, and leadership were key features of these opportunities. The youth noted the connection between learning and fun. In the process, they learned new skills, such as teamwork and public speaking, and developed personal qualities, such as responsibility, that helped them as they were growing up, transferred to other settings, and would benefit them in the future. Findings from this study suggest some clear implications for youth development professionals.

  14. GENDER BIAS AND CHILD LABOR: SPAIN, LATIN AMERICA AND DEVELOPING COUNTRIES FROM A LONG-TERM COMPARATIVE PERSPECTIVE

    Enriqueta Camps-Cura

    2016-11-01

    Full Text Available In this paper, several historical scenarios are compared, each very different to the each other in both institutional and geographical terms. What they have in common is the relative poverty of part of the population. This approach allows combining micro historical analysis (in the Catalan case with a macro comparative approach in developing countries. Through these micro historical and macro regression analyses we obtain the result that adult women’s skills and real wages are a key factor when we wish to explain the patterns of child labor. While female real wages increased sharply in 19th century Catalonia, we obtain very different results in the case of developing countries. This gender bias is identified as one of the very significant effects of human capital which held by women and helps to explain why in some cases children continue to work and also why some parts of the world continue to be poor according to our regression analysis.

  15. Long-Term Sustainability from the Perspective of Cullet Recycling in the Container Glass Industry: Evidence from Italy

    Mario Testa

    2017-10-01

    Full Text Available Glass manufacturing is a high-volume process, during which large substance quantities are transformed into commercial products, and significant amounts of non-renewable resources and energy (i.e., thermal fuels and electrical power are consumed. The main purpose of this study is to give a critical explanation of the performance of the Italian container glass industry from the perspective of cullet being recycled, to outline the opportunities for transition towards circular business models that stimulate innovation in new sectors based on reverse-cycle activities for recycling. In 2015, disparate performances have been achieved as regards the container glass recycling rate in northern, central, and southern Italy, accounting for around 73%, 64%, and 55%, respectively. In fact, only northern Italy is in line with European targets, as by 2025 it will only need to increase its current performance by two percentage points, unlike central and southern Italy that will have to increase performance by, respectively, 11% and 20%. This shows a need to improve the efficiency of municipal waste collection systems in central and southern Italy, where undifferentiated waste still holds appreciable amounts of glass. Consequently, we propose several improvement channels, from the revision of waste legislation to the re-engineering of waste management supply chains.

This study showed for the first time that a short post-weaning social isolation was able to induce long-term changes in the striatal dopaminergic system and increased the response to psychostimulants. These results emphasize the importance of stressful experiences during a short period of development on programming susceptibility to psychostimulants later in life. Copyright © 2017 ISDN.

  17. Exploring futures from an energy perspective. A natural capital accounting model study into the long-term economic development potential of the Netherlands

    Noorman, K.J.

    1995-01-01

    The need to quantify economic activity in physical flows has been stressed several times elsewhere. To relate economic development with 'physical reality', in this thesis Resource Accounting (or Natural Capital Accounting) has been adopted as a method. This physical perspective on sustainable development has been made operational by designing an ECCO (Enhancement of Capital Creation Options) model for the Netherlands using energy as a physical numeraire. The purpose of the model is to investigate the long-term physical aspects of contemporary and future (economic or political) strategies to move the economy towards a more sustainable state and to explore the dynamics of such a process. Chapter 2 deals with the physical nature of economic processes and the fundamental role of thermodynamics in an economic system. Chapter 3 discusses the application of the ECCO paradigm within the context of Natural Capital Accounting methodology. Furthermore, the main structure of an ECCO model is presented. Chapter 4 elaborates on the Dutch model. Historical trends in direct energy use and the methodology of I-O analysis as well as the results of I-O analysis are presented in chapter 5. A method has been developed to estimate the primary energy captured in capital stocks in the diverse ECCO sectors. This method as well as the results, derived from applying this method, are presented in chapter 6. In chapter 7 the application of ECCO as a tool for assessing long term physical consequences of different development strategies is discussed. With respect to reducing the throughput of matter and energy, this study concentrates on energy conservation to reduce the demand for primary energy and the transition to a more sustainable energy supply sector by introducing renewable energy sources. figs., tabs., appendices, refs

  19. A long-term assessment of the variability in winter use of dense conifer cover by female white-tailed deer.

    Glenn D Delgiudice

    Full Text Available Long-term studies allow capture of a wide breadth of environmental variability and a broader context within which to maximize our understanding of relationships to specific aspects of wildlife behavior. The goal of our study was to improve our understanding of the biological value of dense conifer cover to deer on winter range relative to snow depth and ambient temperature.We examined variation among deer in their use of dense conifer cover during a 12-year study period as potentially influenced by winter severity and cover availability. Female deer were fitted with a mixture of very high frequency (VHF, n = 267 and Global Positioning System (GPS, n = 24 collars for monitoring use of specific cover types at the population and individual levels, respectively. We developed habitat composites for four study sites. We fit multinomial response models to VHF (daytime data to describe population-level use patterns as a function of snow depth, ambient temperature, and cover availability. To develop alternative hypotheses regarding expected spatio-temporal patterns in the use of dense conifer cover, we considered two sets of competing sub-hypotheses. The first set addressed whether or not dense conifer cover was limiting on the four study sites. The second set considered four alternative sub-hypotheses regarding the potential influence of snow depth and ambient temperature on space use patterns. Deer use of dense conifer cover increased the most with increasing snow depth and most abruptly on the two sites where it was most available, suggestive of an energy conservation strategy. Deer use of dense cover decreased the most with decreasing temperatures on the sites where it was most available. At all four sites deer made greater daytime use (55 to >80% probability of use of open vegetation types at the lowest daily minimum temperatures indicating the importance of thermal benefits afforded from increased exposure to solar radiation.

  20. Hair as a long-term retrospective cortisol calendar in orang-utans (Pongo spp.): new perspectives for stress monitoring in captive management and conservation.

    Carlitz, Esther H D; Kirschbaum, Clemens; Stalder, Tobias; van Schaik, Carolus P

    2014-01-01

    This study examined whether the method of hair cortisol analysis is applicable to orang-utans (Pongo spp.) and can help to advance the objective monitoring of stress in non-human primates. Specifically, we examined whether fundamental prerequisites for hair cortisol analysis are given in orang-utans and, subsequently, whether segmental hair analysis may provide a retrospective calendar of long-term cortisol levels. For this, hair samples were examined from 71 zoo-living orang-utans (38 males, mean age=22.5years; 33 females, mean age=24years) for which detailed records of past living conditions were available. Hair samples were cut from defined body regions and were analyzed either in full length or in segments. Results showed that hair cortisol concentrations (HCC) were unrelated to age or sex of the individual animal. HCC were found to be higher in orang-utans, with perceived long-term stressful periods (mean HCC=43.6±26.5pg/mg, n=13) compared to animals without perceived stressful periods (19.3±5.5pg/mg, n=55, P40cm. The possibility of obtaining a retrospective calendar of stress-related cortisol changes through hair analysis was further supported by data of three case studies showing close correspondence between the segmental HCC results and keeper reports of stress exposure during the respective time periods. Finally, low within-animal variation in HCC from different body regions (CV%: 14.3) suggested that this method may also be applicable to naturally shed hair, e.g., as found in nests of wild orang-utans and other great apes. Therefore, using HCC may provide an ideal non-invasive tool for both captive management as well as conservation in orang-utans and potentially other great apes. Copyright © 2013 Elsevier Inc.

  2. Perspective for Female Medical Physicists

    Naqvi, Syed Mansoor; Hasnain, Aziz Fatima

    2009-01-01

    Due to cultural and religious reasons, Pakistani women can be reluctant to seek medical attention for disorders affecting their genitals or breasts. As a result, in the case of cervical and breast cancers, oncological treatment is often not received until the diseases are in the late stages. Once a cancer is classified and the tumor marked, the role of the medical physicist begins. Medical physicists' responsibilities include treatment planning, supervising treatment through radiation, dosimetry, contouring, training, equipment selection, education, research, and supervising radiotherapy facilities. In brachytherapy, isotopes are placed at the tumor site in the form of wires or seeds. There are very few female medical physicists in Pakistan. This leads to further hesitation on the part of many women to seek treatment. To help female patients obtain needed medical care, female physics students should be encouraged to pursue the emerging field of medical physics. This would provide a new professional opportunity for female physics students and give comfort to female patients.

  3. Keep going in adversity – using a resilience perspective to understand the narratives of long-term social assistance recipients in Sweden

    2013-01-01

    Full Text Available Abstract Introduction In Sweden, means-tested social assistance serves as a temporary, last resort safety net. However, increasing numbers of people are receiving it for longer periods and about a third has assistance for more than a year. The aim of this study was to explore the ways social assistance recipients manage long lasting adversity and their roles as active, rather than passive, agents in this process, using a resilience perspective. Method The study is based on thirteen in-depth interviews with long-term social assistance recipients from diverse areas in Stockholm County. The interviews were guided by narrative inquiry to interpret and construct stories of experiences and are part of a larger qualitative study exploring experiences of living on social assistance in Sweden. Results Experiences of cumulative adversity during many years compounded recipients’ difficulties in finding ways out of hardship. They had different strategies to deal with adversities, and many had underlying “core problems”, including mental health problems, which had not been properly resolved. Recipients’ showed resistance in adverse situations. Some made attempts to find ways out of hardship, whereas others struggled mainly to achieve a sense of mastering life. They received important support from individual professionals in different authorities, but mostly the help from the welfare system was fragmented. Conclusions Social assistance recipients in this study demonstrated agency in ways of managing long lasting difficulties, sometimes caused by “core problems”, which were often accumulated into complex difficulties. Resilience was about keeping going and resisting these difficulties. To find ways out of social assistance required help from different welfare agencies and professionals and was hindered by the fragmentation of services. This study shows that there is a need for more long-term personalised, comprehensive support, including

    One of the most relevant topics in the field of pelvic floor dysfunction treatment is the long-term efficacy of surgical procedures, in particular, the use of prosthesis. Hence, a systematic review and meta-analysis was conducted to evaluate the long-term effectiveness and safety of midurethral sling (MUS) procedures for stress urinary incontinence (SUI), as reported in randomised controlled trials (RCTs) and non-randomised studies. This systematic review is based on material searched and obtained via PubMed/Medline, Scopus, and the Cochrane Library between January 2000 and October 2016. Peer-reviewed, English-language journal articles evaluating the long-term (≥5 years) efficacy and safety of MUS in women affected by SUI were included. A total of 5,592 articles were found after the search, and excluding duplicate publications, 1,998 articles were available for the review process. Among these studies, 11 RCTs (0.6%) and 5 non-RCTs (0.3%) could be included in the qualitative and quantitative synthesis. Objective and subjective cumulative cure rates for retropubic technique (TVT) and transobturator tape (TOT; both out-in and in-out) were 61.6% (95% CI: 58.5-64.8%) and 76.5% (95% CI: 73.8-79.2%), and 64.4% (95% CI: 61.4-67.4%) and 81.3% (95% CI: 78.9-83.7%) respectively. When considering TOT using the out-in technique (TOT-OI) and TOT using the in-out technique (TVT-O) the objective and subjective cumulative cure rates were 57.2% (95% CI: 53.7-60.7%) and 81.6% (95% CI: 78.8-84.4%), and 68.8% (95% CI: 64.9-72.7%) and 81.3% (95% CI: 77.9-84.7%) respectively. Furthermore, this article demonstrates that both TVT and TOT are associated with similar long-term objectives (OR: 0.87 [95% CI: 0.49-1.53], I 2  = 67%, p = 0.62) and subjective (OR: 0.84 [95% CI: 0.46-1.55], I 2  = 68%, p = 0.58) cure rates. Similarly, no significant difference has been observed between TTOT-OI and TVT-O) in objective (OR: 3.03 [95% CI: 0.97-9.51], I 2  = 76%, p = 0

    Full Text Available With the current status of the technological and medical knowledge advancements the subject of the quality of death and the way one dies has become remarkably important. Such findings have also had their own influences. Therefore, the present study with the objective of comparing the treatment team and the patients’ perspectives regarding euthanasia in conscious patients connected to ventilator with long term ICU stays. the present research is an analytical-descriptive study which has dealt with the comparison of the 123 points of view from a treatment team (physicians and nurses with 100 patients points of view in one of the therapy centers in Gilan Province based on the availability method. The data have been collected by making use of the questionnaires. The data were then analyzed through the use of SPSS software and the application of Spearman, Mann Whitney and Kruskal Wallis Utests as well. The results indicated that that the study population significantly opposed the conduction of euthanasia of any sort respective to the treatment team. There was not observed any significant statistical difference between the matched obtained scores from the general overview of the euthanasia in the studied patients based on the demographic variables (gender, age, education level and hospital stay duration (P>0.05 in the entire cases. From the other side, according to the treatment team education level the results are indicative that the higher the education level of the treatment team the rate of euthanasia acceptance by them would be higher as well. considering the changes and evolutions advancement pace in the current era regarding technology, culture and other cases the medical sciences cannot be excluded from such a principle and the treatment team as the leaders in health area can enhance their care services through attracting the trust and confidence of the patients as the main treatment centers clients.

  10. Designing and evaluating an electronic patient falls reporting system: perspectives for the implementation of health information technology in long-term residential care facilities.

    Mei, Yi You; Marquard, Jenna; Jacelon, Cynthia; DeFeo, Audrey L

    2013-11-01

    Patient falls are the leading cause of unintentional injury and death among older adults. In 2000, falls resulted in over 10,300 elderly deaths, costing the United States approximately $179 million in incidence and medical costs. Furthermore, non-fatal injuries caused by falls cost the United States $19 billion annually. Health information technology (IT) applications, specifically electronic falls reporting systems, can aid quality improvement efforts to prevent patient falls. Yet, long-term residential care facilities (LTRCFs) often do not have the financial resources to implement health IT, and workers in these settings are often not ready to adopt such systems. Additionally, most health IT evaluations are conducted in large acute-care settings, so LTRCF administrators currently lack evidence to support the value of health IT. In this paper, we detail the development of a novel, easy-to-use system to facilitate electronic patient falls reporting within a LTRCF using off-the-shelf technology that can be inexpensively implemented in a wide variety of settings. We report the results of four complimentary system evaluation measures that take into consideration varied organizational stakeholders' perspectives: (1) System-level benefits and costs, (2) system usability, via scenario-based use cases, (3) a holistic assessment of users' physical, cognitive, and marcoergonomic (work system) challenges in using the system, and (4) user technology acceptance. We report the viability of collecting and analyzing data specific to each evaluation measure and detail the relative merits of each measure in judging whether the system is acceptable to each stakeholder. The electronic falls reporting system was successfully implemented, with 100% reporting at 3-months post-implementation. The system-level benefits and costs approach showed that the electronic system required no initial investment costs aside from personnel costs and significant benefits accrued from user time savings

    2012-03-01

    Full Text Available Purpose To assess the long-term outcomes of tension-free vaginal tape (TVT for stress urinary incontinence (SUI with intrinsic sphincter deficiency (ISD and to identify influencing factors for failure in these cases. Methods A total of 136 women who underwent TVT procedures with minimum follow-up duration of 3 years were included in the study. Patients were divided into two groups (non-ISD and ISD groups based on preoperative urodynamic studies. Patient outcomes were assessed from retrospective chart review and telephone research. Cure was defined as the subjective resolution of SUI in any circumstances. Improvement was defined as the subjective improvement of SUI without complete resolution. Failure was defined as the subjective lack of improvement of SUI. Patients in ISD group were subdivided into two subgroups (cure and non-cure groups and were compared to identify influencing factors for TVT procedure failure. Results Eighty-nine patients were in non-ISD group, and 47 in ISD group. The mean follow-up durations were 50.3±9.2 and 49.7±9.7 months, respectively. Subjective cure rate was 75.3% for non-ISD group, and 76.7% for ISD group (P>0.05. Improvement rate was 6.7% for non-ISD group, and 2.1% for ISD group (P>0.05. Satisfaction scores was 3.8±1.2 points in the non-ISD group, and 3.5±1.2 points in ISD group (P>0.05. In ISD subgroups, VLPP was 41.9±12.0 cmH2O for non-cure group, and 50.5±8.6 cmH2O for cure group, and was the only factor that showed significant statistical difference between the two subgroups (P=0.011. Conclusions With our long-term results, TVT is an effective treatment even in women with ISD. However, ISD patients with low VLPP should be counseled carefully about TVT outcome.

  14. Introduction: Long term prediction

    Beranger, G.

    2003-01-01

    Making a decision upon the right choice of a material appropriate to a given application should be based on taking into account several parameters as follows: cost, standards, regulations, safety, recycling, chemical properties, supplying, transformation, forming, assembly, mechanical and physical properties as well as the behaviour in practical conditions. Data taken from a private communication (J.H.Davidson) are reproduced presenting the life time range of materials from a couple of minutes to half a million hours corresponding to applications from missile technology up to high-temperature nuclear reactors or steam turbines. In the case of deep storage of nuclear waste the time required is completely different from these values since we have to ensure the integrity of the storage system for several thousand years. The vitrified nuclear wastes should be stored in metallic canisters made of iron and carbon steels, stainless steels, copper and copper alloys, nickel alloys or titanium alloys. Some of these materials are passivating metals, i.e. they develop a thin protective film, 2 or 3 nm thick - the so-called passive films. These films prevent general corrosion of the metal in a large range of chemical condition of the environment. In some specific condition, localized corrosion such as the phenomenon of pitting, occurs. Consequently, it is absolutely necessary to determine these chemical condition and their stability in time to understand the behavior of a given material. In other words the corrosion system is constituted by the complex material/surface/medium. For high level nuclear wastes the main features for resolving problem are concerned with: geological disposal; deep storage in clay; waste metallic canister; backfill mixture (clay-gypsum) or concrete; long term behavior; data needed for modelling and for predicting; choice of appropriate solution among several metallic candidates. The analysis of the complex material/surface/medium is of great importance

  17. GnRH neurons of young and aged female rhesus monkeys co-express GPER but are unaffected by long-term hormone replacement.

    Naugle, Michelle M; Gore, Andrea C

    2014-01-01

    Menopause is caused by changes in the function of the hypothalamic-pituitary-gonadal axis that controls reproduction. Hypophysiotropic gonadotropin-releasing hormone (GnRH) neurons in the hypothalamus orchestrate the activity of this axis and are regulated by hormonal feedback loops. The mechanisms by which GnRH responds to the primary regulatory sex steroid hormone, estradiol (E2), are still poorly understood in the context of menopause. Our goal was to determine whether the G protein-coupled estrogen receptor (GPER) is co-expressed in adult primate GnRH neurons and whether this changes with aging and/or E2 treatment. We used immunofluorescence double-labeling to characterize the co-expression of GPER in GnRH perikarya and terminals in the hypothalamus. Young and aged rhesus macaques were ovariectomized and given long-term (~2-year) hormone treatments (E2, E2 + progesterone, or vehicle) selected to mimic currently prescribed hormone replacement therapies used for the alleviation of menopausal symptoms in women. We found that about half of GnRH perikarya co-expressed GPER, while only about 12% of GnRH processes and terminals in the median eminence (ME) were double-labeled. Additionally, many GPER-labeled processes were in direct contact with GnRH neurons, often wrapped around the perikarya and processes and in close proximity in the ME. These results extend prior work by showing robust co-localization of GPER in GnRH in a clinically relevant model, and they support the possibility that GPER-mediated E2 regulation of GnRH occurs both in the soma and terminals in nonhuman primates.

  19. Evaluating long term forecasts

    Lady, George M. [Department of Economics, College of Liberal Arts, Temple University, Philadelphia, PA 19122 (United States)

    2010-03-15

    The U.S. Department of Energy's Energy Information Administration (EIA), and its predecessor organizations, has published projections of U.S. energy production, consumption, distribution and prices annually for over 30 years. A natural issue to raise in evaluating the projections is an assessment of their accuracy compared to eventual outcomes. A related issue is the determination of the sources of 'error' in the projections that are due to differences between the actual versus realized values of the associated assumptions. One way to do this would be to run the computer-based model from which the projections are derived at the time the projected values are realized, using actual rather than assumed values for model assumptions; and, compare these results to the original projections. For long term forecasts, this approach would require that the model's software and hardware configuration be archived and available for many years, possibly decades, into the future. Such archival creates many practical problems; and, in general, it is not being done. This paper reports on an alternative approach for evaluating the projections. In the alternative approach, the model is run many times for cases in which important assumptions are changed individually and in combinations. A database is assembled from the solutions and a regression analysis is conducted for each important projected variable with the associated assumptions chosen as exogenous variables. When actual data are eventually available, the regression results are then used to estimate the sources of the differences in the projections of the endogenous variables compared to their eventual outcomes. The results presented here are for residential and commercial sector natural gas and electricity consumption. (author)

  2. What factors are most relevant to the assessment of work ability of employees on long-term sick leave? The physicians' perspective.

    2013-07-01

    To reach insurance physician (IPs) consensus on factors that must be taken into account in the assessment of the work ability of employees who are sick-listed for 2 years. A Delphi study using online questionnaires was conducted from October 2010 to March 2011. One hundred and two insurance physicians reached a consensus on important factors for return to work (RTW) of employees on long-term sick leave; from those factors, the most relevant for the assessment of work ability was determined. From a total of 22 relevant factors considered for the return to work of long-term sick-listed employees, consensus was reached on nine relevant factors that need to be taken into account in the assessment of the work ability of employees on long-term sick leave. Relevant factors that support return to work are motivation, attitude towards RTW, assessment of cognitions and behaviour, vocational rehabilitation in an early stage and instruction for the sick-listed employee to cope with his disabilities. Relevant factors that hinder RTW are secondary gain from illness, negative perceptions of illness, inefficient coping style and incorrect advice of treating physicians regarding RTW. Non-medical personal and environmental factors may either hinder or promote RTW and must be considered in the assessment of the work ability of long-term sick-listed employees. Assessment of work ability should start early during the sick leave period. These factors may be used by IPs to improve the quality of the assessment of the work ability of employees on long-term sick leave.

  3. Post-weaning voluntary exercise exerts long-term moderation of adiposity in males but not in females in an animal model of early-onset obesity.

    Schroeder, Mariana; Shbiro, Liat; Gelber, Vered; Weller, Aron

    2010-04-01

    Given the alarming increase in childhood, adolescent and adult obesity there is an imperative need for understanding the early factors affecting obesity and for treatments that may help prevent or at least moderate it. Exercise is frequently considered as an effective treatment for obesity however the empirical literature includes many conflicting findings. In the present study, we used the OLETF rat model of early-onset hyperphagia-induced obesity to examine the influence of early exercise on peripheral adiposity-related parameters in both males and females. Rats were provided voluntary access to running wheels from postnatal day (PND) 22 until PND45. We examined fat pad weight (brown, retroperitoneal, inguinal and epididymal); inguinal adipocyte size and number; and leptin, adiponectin, corticosterone and creatinine levels. We also examined body weight, feeding efficiency and spontaneous intake. Early voluntary exercise reduced intake, adiposity and leptin in the OLETF males following a sharp reduction in adipocyte size despite a significant increase in fat cell number. Exercising males from the lean LETO control strain presented stable intake, but reduced body fat, feeding efficiency and increased plasma creatinine, suggesting an increment in muscle mass. OLETF females showed reduced feeding efficiency and liver fat, and a significant increase in brown fat. Exercising LETO control females increased intake, body weight and creatinine, but no changes in body fat. Overall, OLETF rats presented higher adiponectin levels than controls in both basal and post-exercise conditions. The results suggest an effective early time frame, when OLETF males can be successfully "re-programmed" through voluntary exercise; in OLETF females the effect is much more moderate. Findings expose sex-dependent peripheral mechanisms in coping with energy challenges. Copyright 2010 Elsevier Inc. All rights reserved.

    This first general study - which has the character of a preliminary study - examines the questions if the liberalisation of the electricity market will have a negative effect on the competitiveness of hydropower in the long-term and what measures can be taken against such effects. Long-term competitiveness is defined as the ability of a business in this sector to make investments in renewal in the long-term, i.e. after its concessions have expired. The three main aims of the study are: 1. Assessment of the long-term competitiveness of the sector and identification of the factors which could either have a negative effect on it or improve it, 2. Analysis of cost structures and presentation of measures through which the long-term competitiveness of the sector can be reinforced, 3. Presentation of possible political measures to be taken in this business area in order to improve the long-term competitiveness of hydropower stations. The study identifies the most important factors that determine future competitiveness as being the market prices for electricity and capital costs (depreciation and interest on own and borrowed capital). Further, water fees, taxes and regulations concerning residual water flow can be of great importance for investment decisions, in particular for those enterprises that operate close to their profitability limits. The results of the analysis indicate that, in the future, a considerable number of enterprises must be reckoned with that will refrain from renewing their plant. Such outcomes depend, of course, on developments in electricity market prices, specific investment costs, rates of interest and other economic, political, and legal conditions. Making a prognosis about the development of such parameters is linked with a high degree of uncertainty. By means of sensitivity calculations and the definition of various scenarios, attempts are made to take these uncertainties into account . Finally, the study makes reference to the fact that

  5. Reproduction impairment and endocrine disruption in female zebrafish after long-term exposure to MC-LR: A life cycle assessment

    2016-01-01

    Microcystin-LR (MC-LR) has been found to cause reproductive and developmental impairments as well as to disrupt sex hormone homeostasis of fish during acute and sub-chronic toxic experiments. However, fish in natural environments are continuously exposed to MC-LR throughout their entire life cycle as opposed to short-term exposure. Here, we tested the hypothesis that the mechanism by which MC-LR harms female fish reproduction and development within natural water bodies is through interference of the reproductive endocrine system. In the present study, zebrafish hatchlings (5 d post-fertilization) were exposed to 0, 0.3, 3 and 30 μg/L MC-LR for 90 d until reaching sexual maturity. Female zebrafish were selected, and the changes in growth and developmental indicators, ovarian ultrastructure as well as the levels of gonadal steroid hormones and vitellogenin (VTG) were examined along with the transcription of related genes in the hypothalamic–pituitary–gonadal–liver axis (HPGL-axis). The results showed for the first time, a life cycle exposure to MC-LR caused growth inhibition, decreased ovary weight and ovarian ultra-pathological lesions. Decreased ovarian testosterone levels indicated that MC-LR disrupted sex steroid hormone balance. Significantly up-regulated transcription of brain FSHβ and LHβ along with ovarian ERα, FSHR and LHR suggested positive feedback regulation in the HPGL-axis was induced as a compensatory mechanism for MC-LR damage. It was also noted that ovarian VTG content and hepatic ERα and VTG1 expression were all down-regulated, which might be responsible for reduced vitellus storage noted in our histological observations. Our findings indicate that a life cycle exposure to MC-LR impairs the development and reproduction of female zebrafish by disrupting the transcription of related HPGL-axis genes, suggesting that MC-LR has potential adverse effects on fish reproduction and thus population dynamics in MCs-contaminated aquatic

    2014-01-01

    The metabolic peptide hormone nesfatin-1 has been linked to the reproductive axis in fishes. The purpose of this study was to determine how energy availability after spawning affects plasma levels of nesfatin-1, the metabolic peptide hormone ghrelin, and sex steroid hormones in rematuring female rainbow trout (Oncorhynchus mykiss). To limit reproductive maturation, a group of female trout was food-restricted after spawning and compared with a control group that was fed a standard broodstock ration. The experiment was conducted twice, once using two-year-old trout (second-time spawners) and once using three-year-old trout (third-time spawners). During monthly sampling, blood was collected from all fish, and a subset of fish from each treatment was sacrificed for pituitaries. Pituitary follicle-stimulating hormone-beta (fsh-β) mRNA expression was analyzed with q-RT-PCR; plasma hormone levels were quantified by radioimmunoassay (17β-estradiol and ghrelin) and enzyme-linked immunosorbent assay (11-keto-testosterone and nesfatin-1). Although plasma nesfatin-1 levels increased significantly in the months immediately after spawning within both feeding treatments, plasma nesfatin-1 did not differ significantly between the two treatments at any point. Similarly, plasma ghrelin levels did not differ significantly between the two treatments at any point. Food restriction arrested ovarian development by 15-20 weeks after spawning, shown by significantly lower plasma E2 levels among restricted-ration fish. Pituitary fsh-β mRNA levels were higher among control-ration fish than restricted-ration fish starting at 20 weeks, but did not differ significantly between treatment groups until 30 weeks after spawning. Within both treatment groups, plasma 11-KT was elevated immediately after spawning and rapidly decreased to and persisted at low levels; starting between 20 and 25 weeks after spawning, plasma 11-KT was higher among control-ration fish than restricted-ration fish.

    2014-01-01

    Infrastructure projects, given their long life, require long term financing. The main sources of long term financings are insurance and pension funds who seek long term investments with low credit risk. However, in India household financial savings are mainly invested in bank deposits. Insurance and pension funds account for only a small percentage of household financial savings. In addition most infrastructure projects do not qualify for investment by insurance and pension funds because of t...

  9. A long-term cohort study of the muscle apparatus of female volleyball players after the application of a compensatory programme

    Full Text Available Volleyball is a sport with great unilateral load that can have a negative impact on a postural system. The aim of the study was to perform a detailed examination of posture and muscle imbalance in elite female volleyball athletes and, according to the results of the examination, to put together compensatory exercises and to assess their effect. A group of elite junior female volleyball players (n = 12 was examined by an experienced physiotherapist using a complex kinesiological analysis especially focused on body posture (from frontal, sagittal and dorsal plane, shortened muscles and performance of basic movement patterns (hip extension, hip abduction, sit-up, cervical flexion, shoulder abduction, push-up. The preliminary examination showed that every tested player had some kind of posture deficiency. The compensatory programme, consisting of breathing techniques, stretching exercises, strengthening exercises with an elastic band, and balance exercises with a Bosu balance trainer, was applied at the end of every training session over the competitive parts of two volleyball seasons. Before the application of the exercise programme we found flat back in 92% subjects, whereas 33% of subjects exhibited it after compensation. Improvement was noted in the intensified lumbar lordosis (from 50% subjects to 42%, and scoliotic body posture (from 50% to 17%. The biggest improvement in shortened muscles in the upper body was observed on the m. levator scapulae (from 83% subjects to 8% and the m. trapezius (from 42% subjects to 8%; and in the lower body m. triceps surae (from 75% subjects to 33% and hip abductors (from 83% subjects to 25%. The study suggests that balance exercises with a Bosu balance trainer and exercises with an exercise elastic band seem to be useful for volleyball since we noted improvement in body posture, movement patterns and muscle shortness. We therefore highly recommend this compensatory programme.

  10. Neonatal vaginal irritation results in long-term visceral and somatic hypersensitivity and increased hypothalamic–pituitary–adrenal axis output in female mice

    Abstract Experiencing early life stress or injury increases a woman's likelihood of developing vulvodynia and concomitant dysregulation of the hypothalamic–pituitary–adrenal (HPA) axis. To investigate the outcome of neonatal vaginal irritation (NVI), female mouse pups were administered intravaginal zymosan on postnatal days 8 and 10 and were assessed as adults for vaginal hypersensitivity by measuring the visceromotor response to vaginal balloon distension (VBD). Western blotting and calcium imaging were performed to measure transient receptor potential ankyrin 1 (TRPA1) and vanilloid 1 (TRPV1) in the vagina and innervating primary sensory neurons. Serum corticosterone (CORT), mast cell degranulation, and corticotropin-releasing factor receptor 1 (CRF1) expression were measured as indicators of peripheral HPA axis activation. Colorectal and hind paw sensitivity were measured to determine cross-sensitization resulting from NVI. Adult NVI mice had significantly larger visceromotor response during VBD than naive mice. TRPA1 protein expression was significantly elevated in the vagina, and calcium transients evoked by mustard oil (TRPA1 ligand) or capsaicin (TRPV1 ligand) were significantly decreased in dorsal root ganglion from NVI mice, despite displaying increased depolarization-evoked calcium transients. Serum CORT, vaginal mast cell degranulation, and CRF1 protein expression were all significantly increased in NVI mice, as were colorectal and hind paw mechanical and thermal sensitivity. Neonatal treatment with a CRF1 antagonist, NBI 35965, immediately before zymosan administration largely attenuated many of the effects of NVI. These results suggest that NVI produces chronic hypersensitivity of the vagina, as well as of adjacent visceral and distant somatic structures, driven in part by increased HPA axis activation.

  11. Cannabis use in male and female first episode of non-affective psychosis patients: Long-term clinical, neuropsychological and functional differences.

    Esther Setién-Suero

    Full Text Available Numerous studies show the existence of a high prevalence of cannabis use among patients with psychosis. However, the differences between men and women who debut with a first episode of psychosis (FEP regarding cannabis use have not been largely explored. The aim of this study was to identify the specific sex factors and differences in clinical evolution associated with cannabis use.Sociodemographic characteristics at baseline were considered in our sample of FEP patients to find differences depending on sex and the use of cannabis. Clinical, functional and neurocognitive variables at baseline, 1-year, and 3-years follow-up were also explored.A total of 549 patients, of whom 43% (N = 236 were cannabis users, 79% (N = 186 male and 21% (N = 50 female, were included in the study. There was a clear relationship between being male and being a user of cannabis (OR = 5.6. Cannabis users were younger at illness onset. Longitudinal analysis showed that women significantly improved in all three dimensions of psychotic symptoms, both in the subgroup of cannabis users and in the non-users subgroup. Conversely, subgroups of men did not show improvement in the negative dimension. In cognitive function, only men presented a significant time by group interaction in processing speed, showing a greater improvement in the subgroup of cannabis users.Despite knowing that there is a relationship between cannabis use and psychosis, due to the high prevalence of cannabis use among male FEP patients, the results showed that there were very few differences in clinical and neurocognitive outcomes between men and women who used cannabis at the start of treatment compared to those who did not.

    Turner, Bruce; Dickens, Nicola

    This article discusses long-term urethral catheterisation, focusing on the relevant anatomy and physiology, indications for the procedure, catheter selection and catheter care. It is important that nurses have a good working knowledge of long-term catheterisation as the need for this intervention will increase with the rise in chronic health conditions and the ageing population.

  15. A unit-level perspective on the long-term sustainability of a nursing best practice guidelines program: An embedded multiple case study.

    2016-01-01

    Best practice guidelines are a tool for narrowing research-to-practice gaps and improving care outcomes. There is some empirical understanding of guideline implementation in nursing settings, yet there has been almost no consideration of the longer-term sustainability of guideline-based practice improvements. Many healthcare innovations are not sustained, underscoring the need for knowledge about how to promote their survival. To understand how a nursing best practice guidelines program was sustained on acute healthcare center nursing units. We undertook a qualitative descriptive case study of an organization-wide nursing best practice guidelines program with four embedded nursing unit subcases. The setting was a large, tertiary/quaternary urban health center in Canada. The nursing department initiated a program to enhance patient safety through the implementation of three guidelines: falls prevention, pressure ulcer prevention, and pain management. We selected four inpatient unit subcases that had differing levels of program sustainability at an average of almost seven years post initial program implementation. Data sources included 39 key informant interviews with nursing leaders/administrators and frontline nurses; site visits; and program-related documents. Data collection and content analysis were guided by a framework for the sustainability of healthcare innovations. Program sustainability was characterized by three elements: benefits, routinization, and development. Seven key factors most accounted for the differences in the level of program sustainability between subcases. These factors were: perceptions of advantages, collaboration, accountability, staffing, linked levels of leadership, attributes of formal unit leadership, and leaders' use of sustainability activities. Some prominent relationships between characteristics and factors explained long-term program sustainability. Of primary importance was the extent to which unit leaders used sustainability

    This work provides an efficiency analysis of the LightForce space debris collision avoidance scheme in the current debris environment and describes a simulation approach to assess its impact on the long-term evolution of the space debris environment. LightForce aims to provide just-in-time collision avoidance by utilizing photon pressure from ground-based industrial lasers. These ground stations impart minimal accelerations to increase the miss distance for a predicted conjunction between two objects. In the first part of this paper we will present research that investigates the short-term effect of a few systems consisting of 10kW class lasers directed by 1.5 m diameter telescopes using adaptive optics. The results found such a network of ground stations to mitigate more than 85 percent of conjunctions and could lower the expected number of collisions in Low Earth Orbit (LEO) by an order of magnitude. While these are impressive numbers that indicate LightForce's utility in the short-term, the remaining 15 percent of possible collisions contain (among others) conjunctions between two massive objects that would add large amount of debris if they collide. Still, conjunctions between massive objects and smaller objects can be mitigated. Hence we choose to expand the capabilities of the simulation software to investigate the overall effect of a network of LightForce stations on the long-term debris evolution. In the second part of this paper, we will present the planed simulation approach for that effort.

  18. Radiocesium in migratory aquatic game birds using contaminated U.S. Department of Energy reactor-cooling reservoirs: A long-term perspective.

    Kennamer, Robert A; Oldenkamp, Ricki E; Leaphart, James C; King, Joshua D; Bryan, A Lawrence; Beasley, James C

    2017-05-01

    Low-level releases of radiocesium into former nuclear reactor cooling-reservoirs on the U.S. Department of Energy's Savannah River Site (SRS) in South Carolina, USA, dating primarily to the late 1950s and early 1960s, have allowed examination of long-term contaminant attenuation in biota occupying these habitats. Periodic collections of migratory game birds since the 1970s have documented 137 Cs (radiocesium) activity concentrations in birds of SRS reservoirs, including mainly Par Pond and Pond B. In this study, during 2014 and 2015 we released wild-caught American coots (Fulica americana) and ring-necked ducks (Aythya collaris) onto Pond B. We made lethal collections of these same birds with residence times ranging from 32 to 173 days to examine radiocesium uptake and estimate the rate of natural attenuation. The two species achieved asymptotic whole-body activity concentrations of radiocesium at different times, with ring-necked ducks requiring almost three times longer than the 30-35 days needed by coots. We estimated ecological half-life (T e ) for Pond B coots over a 28-yr period as 16.8 yr (95% CI = 12.9-24.2 yr). Pond B coot T e was nearly four times longer than T e for coots at nearby Par Pond where radiocesium bioavailability had been constrained for decades by pumping of potassium-enriched river water into that reservoir. T e could not be estimated from long-term data for radiocesium in Pond B diving ducks, including ring-necked ducks, likely because of high variability in residence times of ducks on Pond B. Our results highlight the importance: (1) for risk managers to understand site-specific bio-geochemistry of radiocesium for successful implementation of countermeasures at contaminated sites and (2) of residence time as a critical determinant of observed radiocesium activity concentrations in highly mobile wildlife inhabiting contaminated habitats.

    Treatment with 131 I-MIBG is associated with significant thyroid damage. This study was undertaken to investigate the long-term efficacy of current thyroid prophylaxis, to explore the relationship between thyroid dysfunction and thyroid volume after exposure to 131 I-MIBG and to evaluate the possible negative effects of 131 I - on the parathyroid glands. Of 81 long-term surviving patients with neuroblastoma treated with 131 I-MIBG during the period 1999-2012, 24 were finally evaluated. Patients received thyroxine (T4), methimazole and potassium iodide as thyroid protection. In all patients (para)thyroid function was evaluated and ultrasound investigation of the (para)thyroid gland(s) was performed. Thyroid dysfunction was defined as a plasma thyrotropin concentration >5.0 mU/L (thyrotropin elevation, TE) or as the use of T4 at the time of follow-up. Hyperparathyroidism was defined as a serum calcium concentration above the age-related reference range in combination with an inappropriately high parathyroid hormone level. At a median follow-up of 9.0 years after 131 I-MIBG treatment, thyroid disorders were seen in 12 patients (50 %; 9 with TE, 5 with a thyroid nodule and 1 patient was subsequently diagnosed with differentiated thyroid carcinoma). No significant risk factors for the occurrence of thyroid damage could be identified. In 14 of 21 patients (67 %) in whom thyroid volume could be determined, the volume was considered small (<-2SD) for age and gender. Patients treated with T4 at the time of follow-up had significantly smaller thyroid volumes for age than patients without T4 treatment (p = 0.014). None of the patients was diagnosed with hyperparathyroidism. Thyroid protection during treatment with 131 I-MIBG needs attention and must be further improved, as thyroid disorders are still frequently seen despite current thyroid prophylaxis. Reduced thyroid volume in neuroblastoma survivors may be related to previous 131 I-MIBG therapy or current T4 treatment. No

  1. Female impulsive aggression: a sleep research perspective.

    The rate of violent crimes among girls and women appears to be increasing. One in every five female prisoners has been reported to have antisocial personality disorder. However, it has been quite unclear whether the impulsive, aggressive behaviour among women is affected by the same biological mechanisms as among men. Psychiatric sleep research has attempted to identify diagnostically sensitive and specific sleep patterns associated with particular disorders. Most psychiatric disorders are typically characterized by a severe sleep disturbance associated with decreased amounts of slow wave sleep (SWS), the physiologically significant, refreshing part of sleep. Among men with antisocial behaviour with severe aggression, on the contrary, increased SWS has been reported, reflecting either specific brain pathology or a delay in the normal development of human sleep patterns. In our preliminary study among medication-free, detoxified female homicidal offenders with antisocial personality disorder, the same profound abnormality in sleep architecture was found. From the perspective of sleep research, the biological correlates of severe impulsive aggression seem to share similar features in both sexes.

  2. [Long-term psychiatric hospitalizations].

    Plancke, L; Amariei, A

    2017-02-01

    Long-term hospitalizations in psychiatry raise the question of desocialisation of the patients and the inherent costs. Individual indicators were extracted from a medical administrative database containing full-time psychiatric hospitalizations for the period 2011-2013 of people over 16 years old living in the French region of Nord-Pas-de-Calais. We calculated the proportion of people who had experienced a hospitalization with a duration of 292 days or more during the study period. A bivariate analysis was conducted, then ecological data (level of health-care offer, the deprivation index and the size of the municipalities of residence) were included into a multilevel regression model in order to identify the factors significantly related to variability of long-term hospitalization rates. Among hospitalized individuals in psychiatry, 2.6% had had at least one hospitalization of 292 days or more during the observation period; the number of days in long-term hospitalization represented 22.5% of the total of days of full-time hospitalization in psychiatry. The bivariate analysis revealed that seniority in the psychiatric system was strongly correlated with long hospitalization rates. In the multivariate analysis, the individual indicators the most related to an increased risk of long-term hospitalization were: total lack of autonomy (OR=9.0; 95% CI: 6.7-12.2; P<001); diagnoses of psychological development disorders (OR=9.7; CI95%: 4.5-20.6; P<.001); mental retardation (OR=4.5; CI95%: 2.5-8.2; P<.001): schizophrenia (OR=3.0; CI95%: 1.7-5.2; P<.001); compulsory hospitalization (OR=1.7; CI95%: 1.4-2.1; P<.001); having experienced therapeutic isolation (OR=1.8; CI95%: 1.5-2.1; P<.001). Variations of long-term hospitalization rates depending on the type of establishment were very high, but the density of hospital beds or intensity of ambulatory activity services were not significantly linked to long-term hospitalization. The inhabitants of small urban units had

  6. The Cross-scale Interplay between Social and Biophysical Context and the Vulnerability of Irrigation-dependent Societies: Archaeology's Long-term Perspective

    Margaret C. Nelson

    2010-09-01

    Full Text Available What relationships can be understood between resilience and vulnerability in social-ecological systems? In particular, what vulnerabilities are exacerbated or ameliorated by different sets of social practices associated with water management? These questions have been examined primarily through the study of contemporary or recent historic cases. Archaeology extends scientific observation beyond all social memory and can thus illuminate interactions occurring over centuries or millennia. We examined trade-offs of resilience and vulnerability in the changing social, technological, and environmental contexts of three long-term, pre-Hispanic sequences in the U.S. Southwest: the Mimbres area in southwestern New Mexico (AD 650-1450, the Zuni area in northern New Mexico (AD 850-1540, and the Hohokam area in central Arizona (AD 700-1450. In all three arid landscapes, people relied on agricultural systems that depended on physical and social infrastructure that diverted adequate water to agricultural soils. However, investments in infrastructure varied across the cases, as did local environmental conditions. Zuni farming employed a variety of small-scale water control strategies, including centuries of reliance on small runoff agricultural systems; Mimbres fields were primarily watered by small-scale canals feeding floodplain fields; and the Hohokam area had the largest canal system in pre-Hispanic North America. The cases also vary in their historical trajectories: at Zuni, population and resource use remained comparatively stable over centuries, extending into the historic period; in the Mimbres and Hohokam areas, there were major demographic and environmental transformations. Comparisons across these cases thus allow an understanding of factors that promote vulnerability and influence resilience in specific contexts.

  7. Quantification of long-term wastewater fluxes at the surface water/groundwater-interface: an integrative model perspective using stable isotopes and acesulfame.

    Engelhardt, I; Barth, J A C; Bol, R; Schulz, M; Ternes, T A; Schüth, C; van Geldern, R

    2014-01-01

    The suitability of acesulfame to trace wastewater-related surface water fluxes from streams into the hyporheic and riparian zones over long-term periods was investigated. The transport behavior of acesulfame was compared with the transport of water stable isotopes (δ(18)O or δ(2)H). A calibrated model based on a joint inversion of temperature, acesulfame, and piezometric pressure heads was employed in a model validation using data sets of acesulfame and water stable isotopes collected over 5months in a stream and groundwater. The spatial distribution of fresh water within the groundwater resulting from surface water infiltration was estimated by computing groundwater ages and compared with the predicted acesulfame plume obtained after 153day simulation time. Both, surface water ratios calculated with a mixing equation from water stable isotopes and simulated acesulfame mass fluxes, were investigated for their ability to estimate the contribution of wastewater-related surface water inflow within groundwater. The results of this study point to limitations for the application of acesulfame to trace surface water-groundwater interactions properly. Acesulfame completely missed the wastewater-related surface water volumes that still remained in the hyporheic zone under stream-gaining conditions. In contrast, under stream-losing conditions, which developed after periods of stagnating hydraulic exchange, acesulfame based predictions lead to an overestimation of the surface water volume of up to 25% in the riparian zone. If slow seepage velocities prevail a proportion of acesulfame might be stored in smaller pores, while when released under fast flowing water conditions it will travel further downstream with the groundwater flow direction. Therefore, under such conditions acesulfame can be a less-ideal tracer in the hyporheic and riparian zones and additional monitoring with other environmental tracers such as water stable isotopes is highly recommended. © 2013 Elsevier

  8. Making tradeoffs between the reasons to leave and reasons to stay employed in long-term care homes: perspectives of licensed nursing staff.

    McGilton, Katherine S; Boscart, Veronique M; Brown, Maryanne; Bowers, Barbara

    2014-06-01

    Turnover of licensed nursing staff in long-term care (LTC) settings (e.g., nursing homes) is a mounting concern and is associated with poor quality of care and low staff morale. Retention and turnover research in LTC have focused primarily on direct care workers (i.e., nurse aides) leaving the issues largely unexplored for licensed nursing staff (i.e., registered nurses and licensed practical nurses). The main objective of this study was to understand factors that influence nurses' intentions to remain employed at their current job. Qualitative descriptive study. Seven nursing homes in Ontario, Canada. A convenience sample of forty-one licensed LTC nurses. Data were collected through focus groups conducted at each of the participating nursing homes. Focus group discussions were transcribed verbatim. Directed content analysis was used to identify and develop themes. Work conditions were a salient element affecting nurses' intention to stay and included impact of regulations on nurse role flexibility and professional judgment, an underfunded system contributing to insufficient resources and staffing, and a lack of supportive leadership. Factors promoting nurses' willingness to stay included the development of meaningful relationships with residents and staff and opportunities for learning and professional development. Nurses also considered personal and life circumstances (e.g., marital status and seniority) when discussing intention to stay. Nurses in this study weighed positive and negative work-related factors as well as personal circumstances to determine their intent to stay. Developing a more individualized approach to address attrition of licensed nurses in LTC may be the most successful strategy for improving retention of highly skilled staff in this sector.

    A growing body of evidence suggests the consumption of high-fat diet (HFD) during pregnancy to model maternal obesity and the associated increase in oxidative stress (OS), might act as powerful prenatal stressors, leading to adult stress-related metabolic or behavioral disorders. We hypothesized that administration of antioxidants throughout gestation might counteract the negative effects of prenatal exposure to metabolic challenges (maternal HFD feeding during pregnancy) on the developing fetus. In this study, female C57BL/6J mice were fed HFD for 13 weeks (from 5-weeks of age until delivery) and were exposed to the N-acetyl-cysteine (NAC) antioxidant from 10-weeks of age until right before delivery. Body weight of the offspring was assessed following birth, up to weaning and at adulthood. The metabolic, neuroendocrine and emotional profile of the adult offspring was tested at 3-months of age. Prenatal HFD increased mother's body weight and offspring's weight at the time of weaning, when administered in conjunction with NAC. In females, NAC administration reduced high levels of leptin resulting from prenatal HFD. Prenatal NAC administration also resulted in greater glucose tolerance and insulin sensitivity while increasing adiponectin levels, as well as increasing exploratory behavior, an effect accompanied by reduced plasma corticosterone levels in response to restraint stress. Analysis of glutathione levels in the hypothalamus and in brown adipose tissue indicates that, while HFD administration to pregnant dams led to reduced levels of glutathione in the offspring, as in the male hypothalamus, NAC was able to revert this effect and to increase glutathione levels both in the periphery (Brown Adipose Tissue, both males and females) and in the central nervous system (males). Overall, results from this study indicate that the body redox milieu should be tightly regulated during fetal life and that buffering OS during pregnancy can have important long-term

  11. Quantification of long-term wastewater fluxes at the surface water/groundwater-interface: An integrative model perspective using stable isotopes and acesulfame

    The suitability of acesulfame to trace wastewater-related surface water fluxes from streams into the hyporheic and riparian zones over long-term periods was investigated. The transport behavior of acesulfame was compared with the transport of water stable isotopes (δ{sup 18}O or δ{sup 2}H). A calibrated model based on a joint inversion of temperature, acesulfame, and piezometric pressure heads was employed in a model validation using data sets of acesulfame and water stable isotopes collected over 5 months in a stream and groundwater. The spatial distribution of fresh water within the groundwater resulting from surface water infiltration was estimated by computing groundwater ages and compared with the predicted acesulfame plume obtained after 153 day simulation time. Both, surface water ratios calculated with a mixing equation from water stable isotopes and simulated acesulfame mass fluxes, were investigated for their ability to estimate the contribution of wastewater-related surface water inflow within groundwater. The results of this study point to limitations for the application of acesulfame to trace surface water–groundwater interactions properly. Acesulfame completely missed the wastewater-related surface water volumes that still remained in the hyporheic zone under stream-gaining conditions. In contrast, under stream-losing conditions, which developed after periods of stagnating hydraulic exchange, acesulfame based predictions lead to an overestimation of the surface water volume of up to 25% in the riparian zone. If slow seepage velocities prevail a proportion of acesulfame might be stored in smaller pores, while when released under fast flowing water conditions it will travel further downstream with the groundwater flow direction. Therefore, under such conditions acesulfame can be a less-ideal tracer in the hyporheic and riparian zones and additional monitoring with other environmental tracers such as water stable isotopes is highly recommended

  12. Long term aspects of uranium tailings management

    Bragg, K.

    1980-05-01

    This paper sets out the background issues which lead to the development of interim close-out criteria for uranium mill tailings. It places the current state-of-the-art for tailings management into both a national and international perspective and shows why such interim criteria are needed now. There are seven specific criteria proposed dealing with the need to have: passive barriers, limits on surface water recharge, durable systems, long term performance guarantees, limits to access, controls on water and airborne releases and finally to have a knowledge of exposure pathways. This paper is intended to serve as a focus for subsequent discussions with all concerned parties. (auth)

  13. Nuclear Energy, Long Term Requirements

    Knapp, V.

    2006-01-01

    There are serious warnings about depletion of oil and gas and even more serious warnings about dangers of climate change caused by emission of carbon dioxide. Should developed countries be called to replace CO2 emitting energy sources as soon as possible, and the time available may not be longer then few decades, can nuclear energy answer the call and what are the requirements? Assuming optimistic contribution of renewable energy sources, can nuclear energy expand to several times present level in order to replace large part of fossil fuels use? Paper considers intermediate and long-term requirements. Future of nuclear power depends on satisfactory answers on several questions. First group of questions are those important for near and intermediate future. They deal with economics and safety of nuclear power stations in the first place. On the same time scale a generally accepted concept for radioactive waste disposal is also required. All these issues are in the focus of present research and development. Safer and more economical reactors are targets of international efforts in Generation IV and INPRO projects, but aiming further ahead these innovative projects are also addressing issues such as waste reduction and proliferation resistance. However, even assuming successful technical development of these projects, and there is no reason to doubt it, long term and large-scale nuclear power use is thereby not yet secured. If nuclear power is to play an essential role in the long-term future energy production and in reduction of CO2 emission, than several additional questions must be replied. These questions will deal with long-term nuclear fuel sufficiency, with necessary contribution of nuclear power in sectors of transport and industrial processes and with nuclear proliferation safety. This last issue is more political then technical, thus sometimes neglected by nuclear engineers, yet it will have essential role for the long-term prospects of nuclear power. The

  14. World's trend of national nuclear power policy and long-term perspective of nuclear power and supply and demand of uranium fuels

    Matsuo, Yuji; Nishida, Naoki; Yamaguchi, Yuji; Shimogoori, Kei; Murakami, Tomoko

    2013-01-01

    Based on perspective of nuclear power reflecting latest trend of national nuclear policy, supply and demand of uranium resources until 2035 was evaluated based on latest data. After the Fukushima nuclear accident, Germany and Italy dramatically changed nuclear power to phase out, while United States, Russia, France and Korea as well as China and India continued to promote nuclear power with no essential change of policy. Thus world's nuclear power capacity was foreseen to expand from 389 GW (2010) to 471 GW (2035, low growth case) and 760 GW (2035, high growth case). Following sharp increase of uranium cost after 2005, investment on natural uranium development became active and new operation start of uranium enrichment plants was anticipated in US and Europe, and then both supply and demand of natural uranium and uranium enrichment service would tend to relax until around 2020 and until 2035 extreme tightness of supply and demand might not occur even for high growth case. Uranium demand of Asian region including China and India would be largely expanded with natural uranium from Africa and Australia and uranium enrichment services from US, and Asian high overseas dependence would be continued.

  15. Analysing long term discursive processes

    Horsbøl, Anders

    which extend beyond the single interaction, for instance negotiations or planning processes, seems to have played a less important role, with studies such as Iedema 2001 and Wodak 2000 as exceptions. These long term processes, however, are central to the constitution and workings of organizations......What do timescales - the notion that processes take place or can be viewed within a shorter or longer temporal range (Lemke 2005) - mean for the analysis of discourse? What are the methodological consequences of analyzing discourse at different timescales? It may be argued that discourse analysis...... in general has favored either the analysis of short term processes such as interviews, discussions, and lessons, or the analysis of non-processual entities such as (multimodal) texts, arguments, discursive repertoires, and discourses (in a Foucaultian sense). In contrast, analysis of long term processes...

  16. Comparing long term energy scenarios

    Cumo, M.; Simbolotti, G.

    2001-01-01

    Major projection studies by international organizations and senior analysts have been compared with reference to individual key parameters (population, energy demand/supply, resources, technology, emissions and global warming) to understand trends and implications of the different scenarios. Then, looking at the long term (i.e., 2050 and beyond), parameters and trends have been compared together to understand and quantify whether and when possible crisis or market turbulence might occur due to shortage of resources or environmental problems [it

  17. Long term radioactive waste management

    Lavie, J.M.

    1984-01-01

    In France, waste management, a sensitive issue in term of public opinion, is developing quickly, and due to twenty years of experience, is now reaching maturity. With the launching of the French nuclear programme, the use of radioactive sources in radiotherapy and industry, waste management has become an industrial activity. Waste management is an integrated system dealing with the wastes from their production to the long term disposal, including their identification, sortage, treatment, packaging, collection and transport. This system aims at guaranteing the protection of present and future populations with an available technology. In regard to their long term management, and the design of disposals, radioactive wastes are divided in three categories. This classification takes into account the different radioisotopes contained, their half life and their total activity. Presently short-lived wastes are stored in the shallowland disposal of the ''Centre de la Manche''. Set up within the French Atomic Energy Commission (CEA), the National Agency for waste management (ANDRA) is responsible within the framework of legislative and regulatory provisions for long term waste management in France [fr

  18. Sexually transmitted diseases and HIV. A female perspective.

    Horgan, M

    2012-02-03

    Sexually transmitted diseases have the greatest impact on the health of women. They are frequently asymptomatic, so screening for infection is important in preventing the long-term sequelae which include infertility, ectopic pregnancy, and chronic pelvic pain. HIV continues to increase in the female population and the gynecologic complications associated with it are unique to this population. Use of zidovudine in pregnant HIV-infected women has substantially decreased the rate of vertical transmission of HIV infection. The epidemiologic synergy between HIV and STDs is well recognized and prevention of one is dependent on prevention of the other.

  19. After Childhood Cancer: a Qualitative Study of Family Physician, Parent/Guardian, and Survivor Information Needs and Perspectives on Long-Term Follow-up and Survivorship Care Plans.

    2018-03-19

    Despite support for the provision of a survivorship care plan (SCP) to every cancer survivor, there is a lack of understanding of the needs and preferences of key stakeholders. We examined perspectives of a novel personalized SCP for childhood cancer survivors (CCS), their family, and family physicians (FP). We conducted semi-structured telephone interviews with a purposefully selected sample of CCS, parents/guardians, and FPs. Data included responses to stakeholder cancer care information needs, concerns with or gaps in communication, the perceived role of the FP in the long-term management of CCS care, utility of the SCP, preferred format, and suggestions for improvement. A deductive content analysis was conducted. Twenty-four participants including 8 CCS, 10 parents/guardians, and 6 FPs completed an interview. Four main and several sub-categories emerged. Core categories were coded as (1) informative reference, (2) coordination of follow-up, (3) barriers to follow-up care, and (4) suggestions for improvement and future implementation. The majority of participants preferred an electronic- or web-based format. Overall, the SCP was seen as an informative and concise resource. The SCP was thought to be a valuable tool to foster communication and empower CCSs to become more fully engaged in their own cancer-related health care. FPs viewed the SCP as a useful resource to facilitate and guide the long-term management of the CCS. In addition to the treatment summary, a comprehensive follow-up timeline, personalized lifestyle information, and details on how to access additional psychosocial support were highlighted as important components.

  20. Long-term biodosimetry Redux

    Simon, Steven L.; Bouville, Andre

    2016-01-01

    This paper revisits and reiterates the needs, purposes and requirements of bio-dosimetric assays for long-term dose and health risk assessments. While the most crucial need for bio-dosimetric assays is to guide medical response for radiation accidents, the value of such techniques for improving our understanding of radiation health risk by supporting epidemiological (long-term health risk) studies is significant. As new cohorts of exposed persons are identified and new health risk studies are undertaken with the hopes that studying the exposed will result in a deeper understanding of radiation risk, the value of reliable dose reconstruction is underscored. The ultimate application of biodosimetry in long-term health risk studies would be to completely replace model-based dose reconstruction-a complex suite of methods for retrospectively estimating dose that is commonly fraught with large uncertainties due to the absence of important exposure-related information, as well as imperfect models. While biodosimetry could potentially supplant model-based doses, there are numerous limitations of presently available techniques that constrain their widespread application in health risk research, including limited ability to assess doses received far in the past, high cost, great inter-individual variability, invasiveness, higher than preferred detection limits and the inability to assess internal dose (for the most part). These limitations prevent the extensive application of biodosimetry to large cohorts and should be considered a challenge to researchers to develop new and more flexible techniques that meet the demands of long-term health risk research. Events in recent years, e.g. the Fukushima reactor accident and the increased threat of nuclear terrorism, underscore that any event that results in significant radiation exposures of a group of people will also produce a much larger population, exposed at lower levels, but that likewise needs (or demands) an exposure

  1. Long Term Perspective On Interstellar Flight

    Millis, M. G.

    2017-12-01

    The process and interim findings of a broad interstellar flight assessment is presented. In contrast to precursor mission studies, this assessment takes a longer view and also considers factors that have been underrepresented in prior studies. The goal is to chart a conceptual roadmap for interstellar flight development that takes all the factors into account and ultimately identifies which research options, today, might have the greatest overall impact on future progress. Three envisioned flight eras are examined, the "era of precursors," the "era of infrastructure," and the "unforeseeable future." Several influential factors have typically been missing from prior studies that will now be assessed; a) the impact of different, often implicit, motivations, b) the interdependency of infrastructure with vehicle design, c) the pace of different developments, and d) the enormous energy required for any interstellar mission. Regarding motivations for example, if the driving motivation is to launch soon, then the emphasis is on existing technologies. In contrast, if the motivation is the survival of humanity, then the emphasis would be on 'world ships.' Infrastructure considerations are included in a broader system-level context. Future infrastructure will support multiple in-space activities, not just one mission-vehicle development. Though it may be too difficult to successfully assess, the study will attempt to compare the rates of different developments, such as the pace of Earth-based astronomy, miniaturization, artificial intelligence, infrastructure development, transhumanism, and others. For example, what new information could be acquired after 30 years of further advances in astronomy compared to a space probe with current technology and a 30 year flight time? The final factor of the study is to assess the pace and risks of the enormous energy levels required for interstellar flight. To compare disparate methods, a set of 'meta measures' will be defined and calculated for all the different approaches. For example, rather than comparing performance in terms of rocket specific impulse or sail reflectivity, more general measures like mass, energy, power, time, and efficiency will be used.

  2. Long-term governance for sustainability

    Martell, M.

    2007-01-01

    Meritxell Martell spoke of the long-term aspects of radioactive waste management. She pointed out that decision-making processes need to be framed within the context of sustainability, which means that a balance should be sought between scientific considerations, economic aspects and structural conditions. Focusing on structural aspects, Working Group 3 of COWAM-Spain came to the conclusion that the activity of the regulator is a key factor of long-term management. Another finding is that from a sustainability perspective multi-level governance is more effective for coping with the challenges of radioactive waste management than one tier of government-making decisions. The working group also felt that the current Local Information Committees need to evolve towards more institutionalized and legitimized mechanisms for long-term involvement. Ms. Martell introduced a study comparing the efficiency of economic instruments to advance sustainable development in nuclear communities vs. municipalities in mining areas. The study found that funds transferred to nuclear zones had become a means to facilitate local acceptance of nuclear facilities rather than a means to promote socio-economic development. Another finding is that economic instruments are not sufficient guarantees of sustainable development by themselves; additional preconditions include leadership, vision and entrepreneur-ship on the part of community leaders, private or public investments, among others. Finally, Ms. Martell summarised the challenges faced by the Spanish radioactive waste management programme, which include the need for strategic thinking, designing the future in a participatory fashion, and working with local and regional governments and citizens to devise mechanisms for social learning, economic development and environmental protection.

    2017-03-01

    Full Text Available Americans over age 65 constitute a larger percentage of the population each year: from 14% in 2010 (40 million elderly to possibly 20% in 2030 (70 million elderly. In 2015, an estimated 66 million people provided care to the ill, disabled, and elderly in the United States. In 2000, according to the Centers for Disease Control and Prevention (CDC, 15 million Americans used some form of long-term care: adult day care, home health, nursing home, or hospice. In all, 13% of people over 85 years old, compared with 1% of those ages 65 to 74, live in nursing homes in the United States. Transitions of care, among these various levels of care, are common: Nursing home to hospital transfer, one of the best-studied transitions, occurs in more than 25% of nursing home residents per year. This article follows one patient through several levels of care.

  5. Effect of long-term impact-loading on mass, size, and estimated strength of humerus and radius of female racquet-sports players: a peripheral quantitative computed tomography study between young and old starters and controls.

    % greater in young starters compared with that of the old starters and 14% compared with that in controls, whereas the difference between old starters and controls was 6%, in favor of the former. All these between-group differences were statistically significant. At the distal radius, the player groups differed significantly from controls in the side-to-side bone mineral content, TrD, and aBMD differences only: the young starters' bone mineral content difference was 9% greater, TrD and aBMD differences were 5% greater than those in the controls, and the old starters' TrD and aBMD differences were both 7% greater than those in the controls. In summary, in both of the female player groups, the structural adaptation of the humeral shaft to long-term loading seemed to be achieved through periosteal enlargement of the bone cortex, although this adaptation was clearly better in the young starters. Exercise-induced cortical enlargement was not so clear at the distal radius (a trabecular bone site), and the study suggested that at long bone ends, the trabecular density could be a modifiable factor to built a stronger bone structure. Conventional DXA-based aBMD measurement detected the intergroup differences in the exercise-induced bone gains, although, because it measured two dimensions of bone only, it seemed to underestimate the effect of exercise on the apparent bone strength, especially if the playing had been started during the growing years.

    Puberty is unique in the sense that its onset shows an extraordinary individual variability of about 5 years, the basis of which being still elusive despite research efforts to understand the reason why. Continuing changes in environmental influences and interaction with genetic determinants...... with less obvious changes in menarcheal age. Conceptually, puberty and subsequent reproduction appear now to be influenced by conditions not only at the time when they occur, but also during fetal and perinatal life. In addition, these influences can be apparently opposing since early maturation follows...... fetal malnourishment and postnatal overfeeding. In this review, the semiology and pathophysiology of puberty are discussed in a lifelong developmental perspective....

  7. Long term study of mechanical

    2016-06-01

    Full Text Available In this study, properties of limestone cement concrete containing different replacement levels of limestone powder were examined. It includes 0%, 5%, 10%, 15%, 20% and 25% of limestone powder as a partial replacement of cement. Silica fume was added incorporated with limestone powder in some mixes to enhance the concrete properties. Compressive strength, splitting tensile strength and modulus of elasticity were determined. Also, durability of limestone cement concrete with different C3A contents was examined. The weight loss, length change and cube compressive strength loss were measured for concrete attacked by 5% sodium sulfate using an accelerated test up to 525 days age. The corrosion resistance was measured through accelerated corrosion test using first crack time, cracking width and steel reinforcement weight loss. Consequently, for short and long term, the use of limestone up to 10% had not a significant reduction in concrete properties. It is not recommended to use blended limestone cement in case of sulfate attack. The use of limestone cement containing up to 25% limestone has insignificant effect on corrosion resistance before cracking.

  8. Long-term competence restoration.

    Morris, Douglas R; DeYoung, Nathaniel J

    2014-01-01

    While the United States Supreme Court's Jackson v. Indiana decision and most state statutes mandate determinations of incompetent defendants' restoration probabilities, courts and forensic clinicians continue to lack empirical evidence to guide these determinations and do not yet have a consensus regarding whether and under what circumstances incompetent defendants are restorable. The evidence base concerning the restoration likelihood of those defendants who fail initial restoration efforts is even further diminished and has largely gone unstudied. In this study, we examined the disposition of a cohort of defendants who underwent long-term competence restoration efforts (greater than six months) and identified factors related to whether these defendants were able to attain restoration and adjudicative success. Approximately two-thirds (n = 52) of the 81 individuals undergoing extended restoration efforts were eventually deemed restored to competence. Lengths of hospitalization until successful restoration are presented with implications for the reasonable length of time that restoration efforts should persist. Older individuals were less likely to be restored and successfully adjudicated, and individuals with more severe charges and greater factual legal understanding were more likely to be restored and adjudicated. The significance of these findings for courts and forensic clinicians is discussed.

  9. Uranium ... long-term confidence

    Anon.

    1983-01-01

    Half way through 1983 the outlook for the world's uranium producers was far from bright if one takes a short term view. The readily accessible facts present a gloomy picture. The spot prices of uranium over the past few years decreased from a high of $42-$43/lb to a low of $17 in 1982. It now hovers between $23 and $24. the contract prices negotiated between producers and consumers are not so accessible but they do not reflect the spot price. The reasons why contractual uranium prices do not follow the usual dictates of supply and demand are related to the position in which uranium and associated power industries find themselves. There is public reaction with strong emotional overtones as well as much reduced expectations about the electric power needs of the world. Furthermore the supply of uranium is not guaranteed despite present over production. However the people in the industry, taking the medium- and long-term view, are not despondent

  10. Long-term corrosion studies

    Gdowski, G.

    1998-01-01

    The scope of this activity is to assess the long-term corrosion properties of metallic materials under consideration for fabricating waste package containers. Three classes of metals are to be assessed: corrosion resistant, intermediate corrosion resistant, and corrosion allowance. Corrosion properties to be evaluated are general, pitting and crevice corrosion, stress-corrosion cracking, and galvanic corrosion. The performance of these materials will be investigated under conditions that are considered relevant to the potential emplacement site. Testing in four aqueous solutions, and vapor phases above them, and at two temperatures are planned for this activity. (The environmental conditions, test metals, and matrix are described in detail in Section 3.0.) The purpose and objective of this activity is to obtain the kinetic and mechanistic information on degradation of metallic alloys currently being considered for waste package containers. This information will be used to provide assistance to (1) waste package design (metal barrier selection) (E-20-90 to E-20-92), (2) waste package performance assessment activities (SIP-PA-2), (3) model development (E-20-75 to E-20-89). and (4) repository license application

    estos trabajos compilados contribuyan a la consolidación de la aproximación de LTSER en el sur de Sudamérica dentro de la comunidad académica y también para una mayor integración entre la academia y la sociedad.Since their formal inception in 1980, long-term ecological research (LTER programs have served as a successful organizing framework to create research agendas and funding mechanisms that allow scientists to address meaningful ecological phenomena at the scales they occur. In its 30 years of existence, LTER has expanded its geographic range (currently the International LTER network has more than 40 country members with sites on every continent and disciplinary foci (principally encompassing the natural and social sciences and leading some to call for a name change to long-term socio-ecological research - LTSER. Nonetheless, the temperate and subantarctic biomes of southern South America have lacked formalized long-term research sites and networks. Yet, at the same time, numerous uncoordinated long-term research efforts exist in both Chile and Argentina, and in 2008, the Institute of Ecology and Biodiversity launched Chile’s first concerted effort to link three existing sites (Fray Jorge Forest National Park - 33° S, Senda Darwin Biological Station - 43° S, and Omora Ethnobotanical Park - 55° S. Here, we present a special feature of the Revista Chilena de Historia Natural, dedicated to LTSER, with the aim of 1 providing a synthesis of some of the most emblematic cases of long-term socio-ecological research in Chile; 2 demonstrating the value of these efforts for the integration of research, education and social outcomes, such as decision making; and 3 offering the perspective of a broad array of participants involved in these initiatives, including graduate students and associated programs from Ibero-America and North America. It is our hope that these compiled works will contribute to the consolidation of the LTSER approach in southern South America

  12. Endorsement of Social and Personal Values Predicts the Desirability of Men and Women as Long-Term Partners.

    A prospective romantic partner's desirability as a long-term partner may be affected by the values that he or she endorses. However, few studies have examined the effects of "values" on a person's desirability as a long-term partner. We hypothesized that individuals who endorse social values (vs. personal values) will be perceived as more desirable long-term partners (Hypothesis 1) and that the endorsement of social values will be especially desirable in a male (vs. female) long-term partner (Hypothesis 2). The current study employed a 2 (sex of prospective partner: male vs. female) × 2 (values of prospective partner: personal vs. social) × 2 (physical attractiveness of prospective partner: unattractive vs. highly attractive) mixed-model design. Participants were 339 undergraduates (174 men, 165 women), with ages varying between 18 and 33 years ( M = 19.9, SD = 3.6), and mostly in a romantic relationship (53.7%). Participants reported interest in a long-term relationship with prospective partners depicted in four scenarios (within subjects), each varying along the dimensions of values (personal vs. social) and physical attractiveness (unattractive vs. highly attractive). Individuals endorsing personal values (vs. social values) and men (vs. women) endorsing personal values were rated as less desirable as long-term partners. The current research adds to the partner preferences literature by demonstrating that an individual's ascribed values influence others' perceptions of desirability as a long-term partner and that these effects are consistently sex differentiated, as predicted by an evolutionary perspective on romantic partner preferences.

  14. A Female Therapist's Perspective on Growing Older.

    Fodor, Iris

    2015-11-01

    As an older woman therapist, I find that my life experience grounds me in my work with people of all ages and backgrounds as they deal with life crises, aging issues, and loss. People with whom I work in therapy appreciate the fact that I am older and have had varied life experiences. Gender issues are still central to my work with clients whether I am working with a man or a woman. I am an integrative therapist, with a background in cognitive-behavioral therapy and gestalt therapy. Therapists need to help clients to identify less with their aging bodies and our culture's view of attractiveness, shifting instead to a paradigm that values life experience and the cultivation of wisdom. We need to find ways of embracing what we have learned about life instead of extolling youthful values. As I get older, I more fully appreciate a constructivism framework and life-cycle perspective, focusing on making sense of clients' life narratives. Storytelling and memoirs have both provided a framework for working with clients on coping with the many changes and challenges of life that bring them to therapy and added another layer to my integrative therapeutic work. © 2015 Wiley Periodicals, Inc.

    2015-01-01

    This paper reviews several grid tariff schemes, including flat tariff, time-of-use, time-varying tariff, demand charge and dynamic tariff (DT), from the perspective of the long term incentives. The long term incentives can motivate the owners of flexible demands to change their energy consumption...... behavior in such a way that the power system operation issues, such as system balance and congestion, can be alleviated.

    charges and fees levied from the waste producers. Altogether, financial resources for decommissioning are needed for the following steps: the post-operational phase in which the facility is prepared for dismantling after its final shut-down, dismantling of the radioactive part of the facility, management, storage and disposal of the radioactive waste, restoration of the site, licensing and regulatory supervision of all these steps. Additional means are necessary for the management, storage and disposal of the spent fuel. The way in which the availability of financial resources is secured differs between public owned installations and installations of the private power utilities. In Germany, past practices has resulted in singular contaminated sites of limited extent, mainly during the first half of the 20. century. Those contaminated sites have been or are being cleaned up and redeveloped. In large areas of Saxony and Thuringia, the geological formations permitted the surface and underground mining of Uranium ore. Facilities of the former Soviet-German WISMUT Ltd. where ore was mined and processed from 1946 until the early 1990's can be found at numerous sites. In the course of the re-unification of Germany, the soviet shares of the WISMUT were taken over by the Federal Republic of Germany and the closure of the WISMUT facilities was initiated. In that phase the extent of the damages to the environment and of the necessary remediation work became clear. All mining and milling sites are now closed and are under decommissioning. A comprehensive remediation concept covers all WISMUT sites. Heaps and mill-tailing ponds are transferred into a long-term stable condition. The area of the facilities to be remediated amounts to more than 30 km 2 . Heaps cover a total area of ca. 15,5 km 2 , tailing ponds in which the tailings resulting from the Uranium production are stored as sludges cover 6,3 km 2 ). In total, the remediation issues are very complex and without precedent. The

  19. ERDA's long-term waste management goals and programs

    Perge, A.F.; Trice, V.G. Jr.; Walton, R.D. Jr.

    1976-01-01

    This paper presents an overview of the ERDA's major program for the long-term waste management of radioactive waste and provides a perspective for symposium participants with regard to the interrelationship of specific components of the program that are discussed in detail in other ERDA-sponsored papers. Needs, goals, and plans are reviewed for ERDA's management of the commercially generated wastes which are expected to be delivered to ERDA in accordance with Federal regulations. At present, ERDA responsibilities include long-term management of commercial-level wastes. Possible future regulations may give ERDA responsibility for the long-term management of commercial low-level solid wastes contaminated with transuranic nuclides. Primary planning goals and programs for the development of terminal storage facilities and waste processing technology to produce acceptable waste forms for long-term management are reviewed for each of the waste types identified above. The status of development programs for the long-term management of airborne radionuclides, which may be required at some time in the future, is also reviewed. (author)

  20. Short-Term and Long-Term Educational Mobility of Families: A Two-Sex Approach.

    Song, Xi; Mare, Robert D

    2017-02-01

    We use a multigenerational perspective to investigate how families reproduce and pass their educational advantages to succeeding generations. Unlike traditional mobility studies that have typically focused on one-sex influences from fathers to sons, we rely on a two-sex approach that accounts for interactions between males and females-the process in which males and females mate and have children with those of similar educational statuses and jointly determine the educational status attainment of their offspring. Using data from the Panel Study of Income Dynamics, we approach this issue from both a short-term and a long-term perspective. For the short term, grandparents' educational attainments have a direct association with grandchildren's education as well as an indirect association that is mediated by parents' education and demographic behaviors. For the long term, initial educational advantages of families may benefit as many as three subsequent generations, but such advantages are later offset by the lower fertility of highly educated persons. Yet, all families eventually achieve the same educational distribution of descendants because of intermarriages between families of high- and low-education origin.

  3. Long term wet spent nuclear fuel storage

    1987-04-01

    The meeting showed that there is continuing confidence in the use of wet storage for spent nuclear fuel and that long-term wet storage of fuel clad in zirconium alloys can be readily achieved. The importance of maintaining good water chemistry has been identified. The long-term wet storage behaviour of sensitized stainless steel clad fuel involves, as yet, some uncertainties. However, great reliance will be placed on long-term wet storage of spent fuel into the future. The following topics were treated to some extent: Oxidation of the external surface of fuel clad, rod consolidation, radiation protection, optimum methods of treating spent fuel storage water, physical radiation effects, and the behaviour of spent fuel assemblies of long-term wet storage conditions. A number of papers on national experience are included

  4. Industrial Foundations as Long-Term Owners

    Thomsen, Steen; Poulsen, Thomas; Børsting, Christa Winther

    Short-termism has become a serious concern for corporate governance, and this has inspired a search for institutional arrangements to promote long-term decision-making. In this paper, we call attention to long-term ownership by industrial foundations, which is common in Northern Europe but little...... known in the rest of the world. We use a unique Danish data set to document that industrial foundations are long-term owners that practice long-term governance. We show that foundation ownership is highly stable compared to other ownership structures. Foundation-owned companies replace managers less...... frequently. They have conservative capital structures with low financial leverage. They score higher on an index of long-termism in finance, investment, and employment. They survive longer. Overall, our paper supports the hypothesis that corporate time horizons are influenced by ownership structures...

  9. Filming Critical Female Perspectives: Edward Yang’s The Terrorizers

    Kai-man Chang

    2017-04-01

    Full Text Available From his first film—a twenty-minute short, “Expectations” (1982—to his last—a three-hour masterpiece, 'Yi Yi' (2000—Edward Yang, one of the leading figures of the Taiwan New Cinema movement, devoted his career to portraying the impact of neoliberal capitalism on the lives of the citizens of Taipei. Interestingly, Yang’s films often employ female perspectives to criticize Taiwan’s education system and transnational corporations for perpetuating neoliberal capitalism’s ideology of self-fulfillment and upward mobility. This paper draws upon feminist film theory to investigate the ways in which Yang’s third feature, 'The Terrorizers' (1986, utilizes various innovative cinematic languages to engender a multitude of women’s perspectives to expose male voyeurism and ultimately criticize the impact of neoliberal capitalism in Taipei.

    Adaptation is an automatic neural mechanism supporting the optimization of visual processing on the basis of previous experiences. While the short-term effects of adaptation on behaviour and physiology have been studied extensively, perceptual long-term changes associated with adaptation are still poorly understood. Here, we show that the integration of adaptation-dependent long-term shifts in neural function is facilitated by sleep. Perceptual shifts induced by adaptation to a distorted imag...

  11. Patient empowerment in long-term conditions: development and preliminary testing of a new measure

    2013-01-01

    Background Patient empowerment is viewed by policy makers and health care practitioners as a mechanism to help patients with long-term conditions better manage their health and achieve better outcomes. However, assessing the role of empowerment is dependent on effective measures of empowerment. Although many measures of empowerment exist, no measure has been developed specifically for patients with long-term conditions in the primary care setting. This study presents preliminary data on the development and validation of such a measure. Methods We conducted two empirical studies. Study one was an interview study to understand empowerment from the perspective of patients living with long-term conditions. Qualitative analysis identified dimensions of empowerment, and the qualitative data were used to generate items relating to these dimensions. Study two was a cross-sectional postal study involving patients with different types of long-term conditions recruited from general practices. The survey was conducted to test and validate our new measure of empowerment. Factor analysis and regression were performed to test scale structure, internal consistency and construct validity. Results Sixteen predominately elderly patients with different types of long-term conditions described empowerment in terms of 5 dimensions (identity, knowledge and understanding, personal control, personal decision-making, and enabling other patients). One hundred and ninety seven survey responses were received from mainly older white females, with relatively low levels of formal education, with the majority retired from paid work. Almost half of the sample reported cardiovascular, joint or diabetes long-term conditions. Factor analysis identified a three factor solution (positive attitude and sense of control, knowledge and confidence in decision making and enabling others), although the structure lacked clarity. A total empowerment score across all items showed acceptable levels of internal

    2001-01-01

    The current international climate negotiations (including CoP-6,recently held in The Hague, Netherlands) are mainly concerned with short term actions and barriers, and are experiencing considerable difficulties, as was once again revealed in The Hague. But we should not forget that keeping climate risks under control also demands a long term perspective. Such a perspective demands an estimate of both possible consequences and risks of climate change, and the possible solutions, in terms of strategies, policy measures, consequences and costs. 2 refs

  13. Where are the female science professors? A personal perspective.

    Kamerlin, Shina Caroline Lynn

    2016-01-01

    The first woman to earn a Professorship at a University in Europe was Laura Maria Caterina Bassi, who earned a professorship in physics at the University of Bologna in 1732. Almost 300 years and three waves of feminism later, in 2016, women typically still only comprise 20% (or less) of the number of full professors in Europe. This opinion article will discuss the experiences of being a female academic today and the factors contributing to the academic gender gap from the perspective of a "young" natural scientist, as well as providing constructive suggestions for strategies to empower women in the academic world.

    To determine the presenting systems, complications, stone coincidence in adult patients with primary ureteropelvic junction (UPJ) obstruction seen at King Abdul-Aziz University Hospital, Jeddah, Kingdom of Saudi Arabia. We are also reporting the success rate and long term results of adult pyeloplasty. We reviewed the records of 34 patients who underwent 37 pyeloplasty operations during the period January 1992 through to June 2002. The preoperative radiological diagnosis made by intravenous urogram or renal isotopes scan. We excluded from our study patients with previous history of passage of stones, renal or ureteral surgeries, large renal pelvis stone that may cause UPJ obstruction or abnormalities that may lead to secondry UPJ obstruction such as vesicoureteral reflux. There were 28 male patients and 8 females, their age varied between 16 and 51-years, the mean age was 36.1 years, and 18 (52.9%) patients had concomitant renal stones. Ispsilateral split renal function improved by 3-7% post pyeloplasty in 23 patients, while in one patient the function stayed the same, and in another patient the split function reduced by 4%. T1/2 renal isotopes washout time became less than 15 minutes in 19 patients and less than 20 minutes in 6 patients. Intravenous urogram revealed disappearence of the obstruction at UPJ in 7 patients while in 2 patients it became poorly functioning. Anderson Hynes pyeloplasty is an excellent procedure for treating UPJ obstruction in adults. Our success rate is comparable to the international repoted rates, while our study revealed a higher incidence of concomitant renal stones than the international studies. (author)

  15. Issues for the long term management of radioactive waste

    Schneider, T.; Schieber, C.; Lavelle, S.

    2006-01-01

    High-level radioactive waste are currently managed in interim storage installations, providing an adequate protection of the public and the workers for the short term period. However, the long-term persistence of the radioactivity of the waste gives a new timescale dimension, never experimented by the society for the development of protection systems. In the framework of the European Commission research project 'COWAM-2' (COmmunity WAste Management) dedicated to the governance of radioactive waste management, the issues of 'long term governance' have been addressed by exploring the elements which can contribute to a better integration of the technical and societal time dimensions, taking into account technical, ethical, economic and organizational considerations. The originality of this project is to address the various issues within working groups involving stakeholders from different origins and European countries together with a research team. After a discussion on the time dimensions to be taken into account from the technical and societal perspective, this paper presents, mainly based on the findings of the COWAM-2 project, a brief analysis of the ethical criteria to be considered when future generations are concerned as well as some performance criteria regarding long term governance. Finally, it proposes a discussion on the interest for the radiation protection experts to engage a process with stakeholders concerned by radioactive waste management in order to favour the emergence of a sustainable management responding to the issues at stake and including radiation protection considerations for long term periods.

    Studies investigating long-term health conditions in patients with craniopharyngioma are limited by short follow-up durations and generally do not compare long-term health effects according to initial craniopharyngioma treatment approach. In addition, studies comparing long-term health conditions between patients with childhood- and adult-onset craniopharyngioma report conflicting results. The objective of this study was to analyse a full spectrum of long-term health effects in patients with craniopharyngioma according to initial treatment approach and age group at craniopharyngioma presentation. Cross-sectional study based on retrospective data. We studied a single-centre cohort of 128 patients with craniopharyngioma treated from 1980 onwards (63 patients with childhood-onset disease). Median follow-up since craniopharyngioma presentation was 13 years (interquartile range: 5-23 years). Initial craniopharyngioma treatment approaches included gross total resection ( n  = 25), subtotal resection without radiotherapy ( n  = 44), subtotal resection with radiotherapy ( n  = 25), cyst aspiration without radiotherapy ( n  = 8), and 90 Yttrium brachytherapy ( n  = 21). Pituitary hormone deficiencies (98%), visual disturbances (75%) and obesity (56%) were the most common long-term health conditions observed. Different initial craniopharyngioma treatment approaches resulted in similar long-term health effects. Patients with childhood-onset craniopharyngioma experienced significantly more growth hormone deficiency, diabetes insipidus, panhypopituitarism, morbid obesity, epilepsy and psychiatric conditions compared with patients with adult-onset disease. Recurrence-/progression-free survival was significantly lower after initial craniopharyngioma treatment with cyst aspiration compared with other therapeutic approaches. Survival was similar between patients with childhood- and adult-onset craniopharyngioma. Long-term health conditions were comparable after

    2012-01-01

    Background. Although patients with Hodgkin's lymphoma (HL) achieve prolonged survival, long-term complications are a major cause of morbidity and mortality among long-term survivors of HL. Methods. We retrospectively evaluated long-term complications in 336 HL survivors treated between January 1990 and January 2006 at the Department of Medical Oncology of the Hacettepe University Institute of Oncology who were >16 years old at presentation. All patients were regularly followed up every 3 months for the first 2 years after complete response, biannually for 3 years, and annually after 5 years. Results. Median follow-up was 8.5 years. The mean age (±SD) of the patients at the time of diagnosis was 35.7 ± 13.1 years. The male to female ratio was 61%/39%. During follow-up, 29 second malignancies (8.6%) were diagnosed in 28 patients with HL; 22 were solid tumors and 7 were hematological malignancies. Forty-seven (14.0%) of all patients with HL were found to have thyroid abnormalities. During follow-up, 54 (16.1%) patients developed cardiovascular complications. Overall, 29 (8.6%) patients developed late pulmonary toxicities. The cumulative number of chronic viral infections was 13 (3.9%). Conclusions. Long-term survivors of HL need to be properly followed up not only for disease control but also for evaluation of possible late morbidities to minimize the consequences.

  20. [Participation as Target of Social Medicine and Nursing Care: - Legal Definition of Long-Term Care Dependency - Strategies to Prevent Long-Term Care Dependency].

    Nüchtern, Elisabeth; Gansweid, Barbara; Gerber, Hans; von Mittelstaedt, Gert

    2017-01-01

    Objective: By the "Second Bill to Strengthen Long-Term Care", a new concept of long-term care dependency will be introduced, valid from 2017. Long-term care dependency according to Social Code XI will be defined covering more aspects than today. Therefore, the working group "Nursing Care" of the division "Social Medicine in Practice and Rehabilitation" in the German Society for Social Medicine and Prevention presents their results after working on the social medicine perspective of the definition and prevention of long-term care dependency. Methods: Both the definition and strategies to prevent long-term care dependency are systematically taken into consideration from the point of view of social medicine on the basis of the International Classification of Functioning, Disability and Health (ICF), as long-term care dependency means a defined condition of disability. Results: Both the current and the new concept of long-term care dependency focus activity limitations. The perspective of social medicine considers the interactions of health condition, its effects on daily activities and personal as well as environmental factors. From this point of view approaches for social benefits concerning prevention and rehabilitation can be identified systematically so as to work against the development and progression of long-term care dependency. The reference to the ICF can facilitate the communication between different professions. The new "graduation" of long-term care dependency would allow an international "translation" referring to the ICF. Conclusion: Experts from the field of social medicine as well as those of nursing care, care-givers and nursing researchers have in common the objective that persons in need of nursing care can participate in as many aspects of life of importance to them in an autonomous and self-determined way. The point of view of social medicine on long-term care dependency is fundamental for all occupational groups that are involved and for their

    Full Text Available Long-term prisoner belongs to a particular category of people who are imprisoned in prisons. On the one hand in this group are often heavily demoralized people who committed the most serious crimes, on the other hand it is a group of prisoners, who should be well thought out and programmed the impact of rehabilitation. The situation of man trapped for years poses in a complicated situation not only the prisoners, but also the entire prison staff. They have to take care of the fact that the prison isolation did not cause the state in which convicts form itself in learned helplessness and lack of skills for self-planning and decision-making. In addition, planning the rehabilitation impact of long-term prisoners should not be forgotten that these prisoners in the short or the long term will return to the libertarian environment therefore, should prevent any negative effects of long-term imprisonment. This article presents the main issues related to the execution of imprisonment against long-term prisoners. It is an attempt to systematize the knowledge of this category of people living in prison isolation.

    Full Text Available The number of long-term survivors is increasing in the western countries due to remarkable improvements in the treatment of childhood cancer. The long-term complications of childhood cancer survivors in these countries were brought to light by the childhood cancer survivor studies. In Korea, the 5-year survival rate of childhood cancer patients is approaching 70%; therefore, it is extremely important to undertake similar long-term follow-up studies and comprehensive long-term care for our population. On the basis of the experiences of childhood cancer survivorship care of the western countries and the current Korean status of childhood cancer survivors, long-term follow-up study and long-term care systems need to be established in Korea in the near future. This system might contribute to the improvement of the quality of life of childhood cancer survivors through effective intervention strategies.

    The Swedish Nuclear Fuel and Waste Management Company is responsible for the management and disposal of Sweden's radioactive waste. It is intended to deposit the spent nuclear fuel in a deep geological repository. This repository shall keep the radiotoxic material separated from humans and the environment for extended periods, from decades to millennia and possibly to geological timescales. During this time perspective climate induced changes such as shore-level displacement and evolution of permafrost and ice sheets are expected to occur which may affect the repository. The possible occurrence, extent and duration of these long-term changes, are therefore of interest when considering the assessment of repository performance and safety. The main climate parameters determining both surface and subsurface conditions are temperature and precipitation. As a result of the last advance of the Weichselian ice sheet only few geological archives exist, which contain information on past climatic conditions in Sweden before c 16,000 years BP. The purpose of this literature review is to compile and evaluate available information from Scandinavian, Northern and Central European geological archives, which record climatic conditions during the Weichselian time period. The compilation provides paleotemperature data sets, which may be used to explore the possible evolution of periglacial permafrost in Sweden. This report is a synopsis of 22 publications detailing climatic and environmental changes during the Weichselian time period in Northwestern Europe based on quantified paleotemperature records. Some of the data is presented as temperature curves which were digitised specifically for this report. The time range covered by the different publications varies considerably.

We show that both classic R/S analysis and the modified R/S statistic if enhanced by bootstrapping techniques can be proven very reliable tools to this end. Our findings support persistence and long-term dependence with non-periodic cycles for the Deutsche Mark and the French Franc series. In addition a noisy chaos explanation is favored over fractional Brownian motion. On the contrary, the US Dollar and British Pound were found to exhibit a much more random behavior and lack of any long-term structure.

  8. Long term planning for wind energy development

    Trinick, M.

    1995-01-01

    In a planning system intended to be governed primarily by policies in statutory plans a reasonable horizon for long term planning is 10 years or longer. Because of statutory requirements, developers have no option but to pay due regard to, and take a full part in, long term planning. The paper examines the type of policies which have emerged in the last few years to cater for wind energy development. It canvasses the merits of different types of policies. Finally, it discusses the policy framework which may emerge to cater for development outside NFFO. (Author)

  9. Long-term characteristics of nuclear emulsion

    Naganawa, N; Kuwabara, K

    2010-01-01

    Long-term characteristics of the nuclear emulsion so called 'OPERA film' used in the neutrino oscillation experiment, OPERA, has been studied for 8 years since its production or refreshing after it. In the results, it turned out to be excellent in sensitivity, amount of random noise, and refreshing characteristics. The retention capacity of latent image of tracks was also studied. The result will open the way to the recycling of 7,000,000 emulsion films which will remain not developed after 5 years of OPERA's run, and other long-term experiments with emulsion.

  11. Long-term home care scheduling

    Gamst, Mette; Jensen, Thomas Sejr

    In several countries, home care is provided for certain citizens living at home. The long-term home care scheduling problem is to generate work plans spanning several days such that a high quality of service is maintained and the overall cost is kept as low as possible. A solution to the problem...... provides detailed information on visits and visit times for each employee on each of the covered days. We propose a branch-and-price algorithm for the long-term home care scheduling problem. The pricing problem generates one-day plans for an employee, and the master problem merges the plans with respect...

  12. Long term storage techniques for 85Kr

    Foster, B.A.; Pence, D.T.; Staples, B.A.

    1975-01-01

    As new nuclear fuel reprocessing plants go on stream, the collection of fission product 85 Kr will be required to avoid potential local release problems and long-term atmospheric buildup. Storage of the collected 85 Kr for a period of at least 100 years will be necessary to allow approximately 99.9 percent decay before it is released. A program designed to develop and evaluate proposed methods for long-term storage of 85 Kr is discussed, and the results of a preliminary evaluation of three methods, high pressure steel cylinders, zeolite encapsulation, and clathrate inclusion are presented.

  5. Impact of mining on the female community: a perspective of female miners in the Indian context

    Mrinal K. Ghose [Indian School of Mines, Dhanbad (India). Centre of Mining Environment

    2004-12-01

    India ranks among the top ten mineral producing nations in the world. This paper investigates mineral production and focuses on the total value of minerals produced in the country. However, mining is seen as one of the most 'masculine' of industries and it is believed that women play an insignificant role in it. The paper examines the employment and social perspectives of women in the mineral industry and overviews the Indian Mines Act for providing employment to female miners. It also investigates the employment of women in coal, lignite and metalliferous mines and discusses the impact of mining in the female community. The study reveals that women take part in mining in non-traditional activities and there is a tendency to conceal the fact that women comprise an important part of the work force. The paper highlights the socioeconomic characteristics of women as miners and on the productive roles they play in mining. It also reviews the prospect of female miners with more involvement in the industry and concludes that women's work in mines needs to be valued and enhanced. The paper suggests certain ways that this can be achieved, such as providing training, leading to ability-building, skill enhancement and improved safety in mines.

  6. Long-term energy futures: the critical role of technology

    Grubler, A.

    1999-01-01

    The paper briefly reviews the results of a 5-year study conducted by IIASA jointly with the World Energy Council (WEC) on long term-energy perspectives. After summarizing the study's main findings, the paper addresses the crucial role of technological change in the evolution of long-term energy futures and in responding to key long-term uncertainties in the domains of energy demand growth, economics, as well as environmental protection. Based on most recent empirical and methodological findings, long-term dynamics of technological change portray a number of distinct features that need to be taken account of in technology and energy policy. First, success of innovation efforts and ultimate outcomes of technological are uncertain. Second, new, improved technologies are not a free good, but require continued dedicated efforts. Third, technological knowledge (as resulting from R and D and accumulation of experience, i.e. technological learning) exhibits characteristics of (uncertain) increasing returns. Forth, due to innovation - diffusion lags, technological interdependence, and infrastructure needs (network externalities), rates of change in large-scale energy systems are necessarily slow. This implies acting sooner rather than later as a contigency policy to respond to long-term social, economic and environmental uncertainties, most notably possible climate change. Rather than picking technological 'winners' the results of the IIASA-WEC scenario studies are seen most appropriate to guide technology and R and D portfolio analysis. Nonetheless, robust persistent patterns of technological change invariably occur across all scenarios. Examples of primising groups of technologies are given. The crucial importance of meeting long-energy demand in developing countries, assuring large-scale infrastructure investments, maintaining a strong and diversified R AND D protfolio, as well as to dvise new institutional mechnisms for technology development and diffusion for instance

  7. Designing indicators of long-term energy supply security

    Jansen, J.C.; Van Arkel, W.G.; Boots, M.G.

    2004-01-01

    To our knowledge, so far amazingly little research work has been undertaken to construct meaningful indicators of long-run energy supply security for a particular nation or region. Currently, in addressing energy supply security, policy makers tend to emphasise short-term supply disruptions. In contrast, this pre-study accords with the broader Sustainability Outlook in considering the long-term perspective. This report starts with taking stock, in a concise way, of the official EU energy outlook and issues related to the opportunities to administer changes in the energy mix at the level of major energy use categories. Then a brief survey of relevant literature is made on long-term strategies to ensure survival of systems - be it biological, social, etc. - in an environment largely characterised by high uncertainty and a lot of unchartered territory. We found the work of Andrew Stirling very inspiring in this context. Based on his work and considering the limitations of the present research activity, we retained the Shannon index as the best 'simple' indicator of diversity. In the core of the report, the Shannon index is elaborated into four indicators of long-term energy supply security. Stepwise, additional aspects of long-term energy supply security are introduced. These aspects are: Diversification of energy sources in energy supply; Diversification of imports with respect to imported energy sources; Long-term political stability in regions of origin; The resource base in regions of origin, including the home region/country itself. After small adjustments to allow for data availability, these indicators were applied to the reference year 2030 of four long-term scenarios with data of base year 1995 and projections for underlying variables provided by the Netherlands Environmental Assessment Agency (MNP). Preliminary interpretation of the results suggests the usefulness of the indicators presented in this report. A second activity undertaken in this report was

  8. Postmortem analysis of encapsulation around long-term ventricular endocardial pacing leads.

    1999-02-01

    To analyze the site and thickness of encapsulation around ventricular endocardial pacing leads and the extent of tricuspid valve adhesion, from today's perspective, with implications for lead removal and sensor location. Gross cardiac postmortem analysis was performed in 11 cases (8 female and 3 male patients; mean age, 78+/-7 years). None of the patients had died because of pacemaker malfunction. The mean implant time was 61+/-60 months (range, 4 to 184). The observations ranged from encapsulation only at the tip of the pacing lead to complete encapsulation along the entire length of the pacing lead within the right ventricle. Substantial areas of adhesion at the tricuspid valve apparatus were noted in 7 of the 11 cases (64%). The firmly attached leads could be removed only by dissection, and in some cases, removal was possible only by damaging the associated structures. No specific optimal site for sensor placement could be identified along the ventricular portion of the pacing leads; however, the fibrotic response was relatively less prominent in the atrial chamber. Extensive encapsulation is present in most long-term pacemaker leads, which may complicate lead removal. The site and thickness of encapsulation seem to be highly variable. Tricuspid valve adhesion, which is usually underestimated, may be severe. In contrast to earlier reports, our study demonstrates that the extent of fibrotic encapsulation may not be related to the duration since lead implantation. Moreover, we noted no ideal encapsulation-free site for sensors on the ventricular portion of long-term pacing leads.

    The association of sub-optimal selenium status with increased risk factors for some cancers has been reported in two recent epidemiological studies. In both studies the same threshold in selenium status was observed, below which, cancer incidence increased. To assess the use of nails as a biologic monitor to measure the long-term selenium status, an eight-year longitudinal study was undertaken with a group of 11 adult subjects, 5 women and 6 men. Selenium has been measured by instrumental neutron activation analysis. Differences between fingernails and toenails with be discussed. In addition, the results will be discussed in the context of the long-term stability of the nail monitor to measure selenium status during those periods when selenium determinants are static; and the changes that occur as a result of selenium supplementation.

  10. Influenza in long-term care facilities.

    Lansbury, Louise E; Brown, Caroline S; Nguyen-Van-Tam, Jonathan S

    2017-09-01

    Long-term care facility environments and the vulnerability of their residents provide a setting conducive to the rapid spread of influenza virus and other respiratory pathogens. Infections may be introduced by staff, visitors or new or transferred residents, and outbreaks of influenza in such settings can have devastating consequences for individuals, as well as placing extra strain on health services. As the population ages over the coming decades, increased provision of such facilities seems likely. The need for robust infection prevention and control practices will therefore remain of paramount importance if the impact of outbreaks is to be minimised. In this review, we discuss the nature of the problem of influenza in long-term care facilities, and approaches to preventive and control measures, including vaccination of residents and staff, and the use of antiviral drugs for treatment and prophylaxis, based on currently available evidence. © 2017 The Authors.

    2016-01-01

    in Denmark. Industrial foundations are independent legal entities without owners or members typically with the dual objective of preserving the company and using excess profits for charity. We use a unique Danish data set to examine the governance of foundation-owned companies. We show that they are long......-term in several respects. Foundations hold on to their shares for longer. Foundation-owned companies replace managers less frequently. They have more conservative capital structures with less leverage. Their companies survive longer. Their business decisions appear to be more long term. This paper supports...... the hypothesis that time horizons are influenced by ownership structures and particularly that industrial foundations promote longtermism. Policymakers which are interested in promoting longtermism should allow and perhaps even encourage the creation of industrial foundations. More generally they should consider...

  12. Analysis of long-term energy scenarios

    Lemming, J.; Morthorst, P.E.

    1998-09-01

    When addressing the role of fusion energy in the 21. century, the evaluation of possible future structures in the electricity market and the energy sector as a whole, can be a useful tool. Because fusion energy still needs demonstration, commercialized fusion energy is not likely to be a reality within the next few decades. Therefore long-term scenarios are needed describing the energy markets, which fusion energy eventually will be part of. This report performs an analysis of two of the most detailed existing long-term scenarios describing possible futures of the energy system. The aim is to clarify the frames in which the future development of the global energy demand, as well as the structure of the energy system can be expected to develop towards the year 2100.

  13. Long-term effects of radiation

    Smith, J.; Smith, T.

    1981-01-01

    It is pointed out that sources of long-term damage from radiation are two-fold. People who have been exposed to doses of radiation from initial early fallout but have recovered from the acute effects may still suffer long-term damage from their exposure. Those who have not been exposed to early fallout may be exposed to delayed fallout, the hazards from which are almost exclusively from ingesting strontium, caesium and carbon isotopes present in food; the damage caused is relatively unimportant compared with that caused by the brief doses from initial radiation and early fallout. A brief discussion is presented of the distribution of delayed long-lived isotope fallout, and an outline is sketched of late biological effects, such as malignant disease, cataracts, retarded development, infertility and genetic effects.

    Vicente, Renato; Pereira, Carlos de B.; Leite, Vitor B. P.; Caticha, Nestor

    2007-07-01

    We employ the Bayesian framework to define a cointegration measure aimed to represent long term relationships between time series. For visualization of these relationships we introduce a dissimilarity matrix and a map based on the sorting points into neighborhoods (SPIN) technique, which has been previously used to analyze large data sets from DNA arrays. We exemplify the technique in three data sets: US interest rates (USIR), monthly inflation rates and gross domestic product (GDP) growth rates.

    2016-01-01

    Background With the recent emergence of conjugated bile acids as signaling molecules in cancer, a murine model of obstructive jaundice by cholestasis with long-term survival is in need. Here, we investigated the characteristics of 3 murine models of obstructive jaundice. Methods C57BL/6J mice were used for total ligation of the common bile duct (tCL), partial common bile duct ligation (pCL), and ligation of left and median hepatic bile duct with gallbladder removal (LMHL) models. Survival was assessed by Kaplan-Meier method. Fibrotic change was determined by Masson-Trichrome staining and Collagen expression. Results 70% (7/10) of tCL mice died by Day 7, whereas majority 67% (10/15) of pCL mice survived with loss of jaundice. 19% (3/16) of LMHL mice died; however, jaundice continued beyond Day 14, with survival of more than a month. Compensatory enlargement of the right lobe was observed in both pCL and LMHL models. The pCL model demonstrated acute inflammation due to obstructive jaundice 3 days after ligation but jaundice rapidly decreased by Day 7. The LHML group developed portal hypertension as well as severe fibrosis by Day 14 in addition to prolonged jaundice. Conclusion The standard tCL model is too unstable with high mortality for long-term studies. pCL may be an appropriate model for acute inflammation with obstructive jaundice but long term survivors are no longer jaundiced. The LHML model was identified to be the most feasible model to study the effect of long-term obstructive jaundice. PMID:27916350

  16. Long-term course of opioid addiction.

    Hser, Yih-Ing; Evans, Elizabeth; Grella, Christine; Ling, Walter; Anglin, Douglas

    2015-01-01

    Opioid addiction is associated with excess mortality, morbidities, and other adverse conditions. Guided by a life-course framework, we review the literature on the long-term course of opioid addiction in terms of use trajectories, transitions, and turning points, as well as other factors that facilitate recovery from addiction. Most long-term follow-up studies are based on heroin addicts recruited from treatment settings (mostly methadone maintenance treatment), many of whom are referred by the criminal justice system. Cumulative evidence indicates that opioid addiction is a chronic disorder with frequent relapses. Longer treatment retention is associated with a greater likelihood of abstinence, whereas incarceration is negatively related to subsequent abstinence. Over the long term, the mortality rate of opioid addicts (overdose being the most common cause) is about 6 to 20 times greater than that of the general population; among those who remain alive, the prevalence of stable abstinence from opioid use is low (less than 30% after 10-30 years of observation), and many continue to use alcohol and other drugs after ceasing to use opioids. Histories of sexual or physical abuse and comorbid mental disorders are associated with the persistence of opioid use, whereas family and social support, as well as employment, facilitates recovery. Maintaining opioid abstinence for at least five years substantially increases the likelihood of future stable abstinence. Recent advances in pharmacological treatment options (buprenorphine and naltrexone) include depot formulations offering longer duration of medication; their impact on the long-term course of opioid addiction remains to be assessed.

  19. French Approach for Long Term Storage Safety

    Marciano, Jacob; Carreton, Jean-Pierre; Lizot, Marie Therese; Lhomme, Veronique

    2014-01-01

    IRSN presents its statement regarding long-term storage facilities; in France, the regulatory documents do not define the long term duration. The storage facility lifetime can only be appreciated according to the needs and materials stored therein. However, the magnitude of the long-term can be estimated at a few hundred years compared to a few decades for current storage. Usually, in France, construction of storage facilities is driven from the necessity various necessities, linked to the management of radioactive material (eg spent fuel) and to the management of radioactive waste. Because of the variety of 'stored materials and objects' (fission product solutions, plutonium oxide powders, activated solids, drums containing technological waste, spent fuel...), a great number of storage facility design solutions have been developed (surface, subsurface areas, dry or wet conditions...) in the World. After describing the main functions of a storage facility, IRSN displays the safety principles and the associated design principles. The specific design principles applied to particular storage (dry or wet spent fuel storage, depleted uranium or reprocessed uranium storage, plutonium storage, waste containing tritium storage, HLW and ILLW storage...) are also presented. Finally, the concerns due to the long-term duration storage and related safety assessment are developed. After discussing these issues, IRSN displays its statement. The authorization procedures governing the facility lifetime are similar to those of any basic nuclear installation, the continuation of the facility operation remaining subject to periodic safety reviews (in France, every 10 years). The applicant safety cases have to show, that the safety requirements are always met; this requires, at minimum, to take into account at the design stage, comfortable design margins. (author)

    Long-term investors face a common problem-how to maintain the purchasing power of their assets over time and achieve a level of real returns consistent with their investment objectives. While inflation-linked bonds and derivatives have been developed to hedge the effects of inflation, their limited supply and liquidity lead many investors to continue to rely on the indirect hedging properties of traditional asset classes. In this paper, we assess these properties over different time horizons,...

    This paper examines the adequacy of world economic uranium resources to meet requirements in the very long term, that is until at least 2025 and beyond. It does so by analysing current requirements forecasts, existing and potential production centre supply capability schedules and national resource estimates. It takes into account lead times from resource discovery to production and production rate limitations. The institutional and political issues surrounding the question of adequacy are reviewed.

    Heinen, Esther; Birkholz, Peter; Willmes, Klaus; Neuschaefer-Rube, Christiane

    2017-10-01

    To explore possible effects of tongue piercing on perceived speech quality. Using a quasi-experimental design, we analyzed the effect of tongue piercing on speech in a perception experiment. Samples of spontaneous speech and read speech were recorded from 20 long-term pierced and 20 non-pierced individuals (10 males, 10 females each). The individuals having a tongue piercing were recorded with attached and removed piercing. The audio samples were blindly rated by 26 female and 20 male laypersons and by 5 female speech-language pathologists with regard to perceived speech quality along 5 dimensions: speech clarity, speech rate, prosody, rhythm and fluency. We found no statistically significant differences for any of the speech quality dimensions between the pierced and non-pierced individuals, neither for the read nor for the spontaneous speech. In addition, neither length nor position of piercing had a significant effect on speech quality. The removal of tongue piercings had no effects on speech performance either. Rating differences between laypersons and speech-language pathologists were not dependent on the presence of a tongue piercing. People are able to perfectly adapt their articulation to long-term tongue piercings such that their speech quality is not perceptually affected.

  8. Sexuality and Physical Intimacy in Long Term Care: Sexuality, long term care, capacity assessment

    Lichtenberg, Peter A.

    2014-01-01

    Sexuality and sexual needs in older adults remains a neglected area of clinical intervention, particularly so in long term care settings. Because older adults in medical rehabilitation and long term care beds present with significant frailties, and often significant neurocognitive disorders it makes it difficult for occupational therapists and other staff to evaluate the capacity of an older adult resident to participate in sexual relationships. The current paper reviews the current literatur...

  9. Management challenges faced by managers of New Zealand long-term care facilities.

    Madas, E; North, N

    2000-01-01

    This article reports on a postal survey of 78 long-term care managers in one region of New Zealand, of whom 45 (58%) responded. Most long-term care managers (73.2%) were middle-aged females holding nursing but not management qualifications. Most long-term care facilities (69%) tended to be stand-alone facilities providing a single type of care (rest home or continuing care hospital). The most prominent issues facing managers were considered to be inadequate funding to match the growing costs of providing long-term care and occupancy levels. Managers believed that political/regulatory, economic and social factors influenced these issues. Despite a turbulent health care environment and the challenges facing managers, long-term care managers reported they were coping well and valued networking.

  10. Finding The Baseline--Putting Recent Eutrophication Of Two South Texas Coastal Water Bodies Into Perspective By Using Sedimentary Records To Examine The Long-Term, Natural Variability Of The Systems

    reservoirs along the Nueces River, the primary inflow for the system. The lack of long-term environmental monitoring records makes it difficult to disentangle the complex interrelationships between the natural and anthropogenic factors that have contributed to eutrophication. To address this issue, we are examining proxy evidence from sediment cores to look back in time, and understand the true baseline conditions and natural variability of these systems long before they were affected by anthropogenic impacts. We are using a suite of geological, chemical, and biological indicators including color spectral reflectance (for total chlorophyll content), organic carbon content via loss-on-ignition, Terrigenous/Aquatic Ratio (TARHC), TOC, C/N ratio analysis, pigment analysis via HPLC, and microfossil assemblage analysis. Age control for the stratigraphy will be provided by radiometric age analyses using 137Cs, 210Pb, and 14C. Initial results from spectral reflectance scanning of sediment cores from the Nueces Estuary appear to indicate an increased chlorophyll content up core, which probably reflects a long-term increase of primary productivity in the system.

    Energy planning and policy development require an in-depth assessment of energy resources and long-term demand forecast estimates. Pakistan, unfortunately, lacks reliable data on its energy resources as well do not have dependable long-term energy demand forecasts. As a result, the policy makers could not come up with an effective energy policy in the history of the country. Energy demand forecast has attained greatest ever attention in the perspective of growing population and diminishing fo...

Application to the specific case of Belgium/A perspective on the national implementation of the conventions to nuclear activities. Long-term operation of NPP's measured by the yardstick of environmental impact assessment and public participation

    Beyens, Marc

    2017-01-01

    Mr Beyens illustrated the challenges regarding the applicability of the concepts of environmental impact assessment and public participation, as defined in the Aarhus and Espoo Conventions and the relevant directives of the European Union, to the federal laws extending the operation of two nuclear power plants in Belgium. The Belgian authorities considered that those laws only opened the possibility to extend the operational period of those nuclear plants, subject to conditions set by the Belgian regulatory authority. Therefore, these laws should be considered as 'policies', exempt from the requirements of environmental impact assessment and public participation. In addition, Mr Beyens explained that, after an environmental screening had been carried out, the regulator ruled that its decision to authorise the long-term operation project did not require an environmental impact assessment, since it considered that the modifications to the installations would not significantly impact existing radiological environmental effects. However, in both instances legal challenges have been filed before the constitutional and administrative courts and are still pending. It is possible that a request for a preliminary ruling be submitted to the Court of Justice of the European Union in this regard

  15. LONG-TERM OUTCOME IN PEDIATRIC TRICHOTILLOMANIA.

    Schumer, Maya C; Panza, Kaitlyn E; Mulqueen, Jilian M; Jakubovski, Ewgeni; Bloch, Michael H

    2015-10-01

    To examine long-term outcome in children with trichotillomania. We conducted follow-up clinical assessments an average of 2.8 ± 0.8 years after baseline evaluation in 30 of 39 children who previously participated in a randomized, double-blind, placebo-controlled trial of N-acetylcysteine (NAC) for pediatric trichotillomania. Our primary outcome was change in hairpulling severity on the Massachusetts General Hospital Hairpulling Hospital Hairpulling Scale (MGH-HPS) between the end of the acute phase and follow-up evaluation. We also obtained secondary measures examining styles of hairpulling, comorbid anxiety and depressive symptoms, as well as continued treatment utilization. We examined both correlates and predictors of outcome (change in MGH-HPS score) using linear regression. None of the participants continued to take NAC at the time of follow-up assessment. No significant changes in hairpulling severity were reported over the follow-up period. Subjects reported significantly increased anxiety and depressive symptoms but improvement in automatic pulling symptoms. Increased hairpulling symptoms during the follow-up period were associated with increased depression and anxiety symptoms and increased focused pulling. Older age and greater focused pulling at baseline assessment were associated with poor long-term prognosis. Our findings suggest that few children with trichotillomania experience a significant improvement in trichotillomania symptoms if behavioral treatments are inaccessible or have failed to produce adequate symptom relief. Our findings also confirm results of previous cross-sectional studies that suggest an increased risk of depression and anxiety symptoms with age in pediatric trichotillomania. Increased focused pulling and older age among children with trichotillomania symptoms may be associated with poorer long-term prognosis. © 2015 Wiley Periodicals, Inc.

  16. Long-term EEG in children.

    Montavont, A; Kaminska, A; Soufflet, C; Taussig, D

    2015-03-01

    Long-term video-EEG corresponds to a recording ranging from 1 to 24 h or even longer. It is indicated in the following situations: diagnosis of epileptic syndromes or unclassified epilepsy, pre-surgical evaluation for drug-resistant epilepsy, follow-up of epilepsy or in cases of paroxysmal symptoms whose etiology remains uncertain. There are some specificities related to paediatric care: a dedicated pediatric unit; continuous monitoring covering at least a full 24-hour period, especially in the context of pre-surgical evaluation; the requirement of presence by the parents, technician or nurse; and stronger attachment of electrodes (cup electrodes), the number of which is adapted to the age of the child. The chosen duration of the monitoring also depends on the frequency of seizures or paroxysmal events. The polygraphy must be adapted to the type and topography of movements. It is essential to have at least an electrocardiography (ECG) channel, respiratory sensor and electromyography (EMG) on both deltoids. There is no age limit for performing long-term video-EEG even in newborns and infants; nevertheless because of scalp fragility, strict surveillance of the baby's skin condition is required. In the specific context of pre-surgical evaluation, long-term video-EEG must record all types of seizures observed in the child. This monitoring is essential in order to develop hypotheses regarding the seizure onset zone, based on electroclinical correlations, which should be adapted to the child's age and the psychomotor development.

    We develop an agency model of financial contracting. We derive long-term debt, a line of credit, and equity as optimal securities, capturing the debt coupon and maturity; the interest rate and limits on the credit line; inside versus outside equity; dividend policy; and capital structure dynamics. The optimal debt-equity ratio is history dependent, but debt and credit line terms are independent of the amount financed and, in some cases, the severity of the agency problem. In our model, the ag...

    Patterns of benzodiazepine (BZD) use and long-term use among young adults are not well known. Our aim was to study trends in BZD use and long-term use among 18-25-year-old young adults by gender and active substance in a nationwide retrospective longitudinal register-based setting. All Finns aged 18-25 years with reimbursed purchases of BZDs in 2006-2014 recorded to the Finnish Prescription Register were included. Annual prevalence rates of BZD use and long-term use among young adults were reported overall, according to gender, drug group (anxiolytic or hypnotic), and active substance. Long-term use of BZDs was defined as purchasing ≥180 Defined Daily Doses (DDDs) in at least two drug purchases during a calendar year. Overall prevalence of BZD use among young adults decreased from 24.0 to 18.8 users per 1000 inhabitants in 2006-2014. Prevalence of long-term use decreased from 5.5 to 3.3 users per 1000 inhabitants. Overall BZD use was higher among females, whereas long-term use was more common among males. Use of anxiolytics was more common than use of hypnotics. Oxazepam, alprazolam, zopiclone, and zolpidem were the most used BZDs, whereas alprazolam and clonazepam were the substances with most long-term use. The use and long-term use of BZDs have decreased annually since 2008 among Finnish young adults. Further research is needed to investigate the reasons behind the decline.

  20. Long-term environmental behaviour of radionuclides

    Brechignac, F.; Moberg, L.; Suomela, M.

    2000-04-01

    The radioactive pollution of the environment results from the atmospheric nuclear weapons testing (during the mid-years of twentieth century), from the development of the civilian nuclear industry and from accidents such as Chernobyl. Assessing the resulting radiation that humans might receive requires a good understanding of the long-term behaviour of radionuclides in the environment. This document reports on a joint European effort to advance this understanding, 3 multinational projects have been coordinated: PEACE, EPORA and LANDSCAPE. This report proposes an overview of the results obtained and they are presented in 6 different themes: i) redistribution in the soil-plant system, ii) modelling, iii) countermeasures, iv) runoff v) spatial variations, and vi) dose assessment. The long term behaviour of the radionuclides 137 Cs, 90 Sr and 239-240 Pu is studied through various approaches, these approaches range from in-situ experiments designed to exploit past contamination events to laboratory simulations. A broad scope of different ecosystems ranging from arctic and boreal regions down to mediterranean ones has been considered. (A.C.)

  1. Craniopharyngioma in Children: Long-term Outcomes

    STEINBOK, Paul

    2015-01-01

    The survival rate for childhood craniopharyngioma has been improving, with more long-term survivors. Unfortunately it is rare for the patient to be normal, either from the disease itself or from the effects of treatment. Long-term survivors of childhood craniopharyngioma suffer a number of impairments, which include visual loss, endocrinopathy, hypothalamic dysfunction, cerebrovascular problems, neurologic and neurocognitive dysfunction. Pituitary insufficiency is present in almost 100%. Visual and hypothalamic dysfunction is common. There is a high risk of metabolic syndrome and increased risk of cerebrovascular disease, including stroke and Moyamoya syndrome. Cognitive, psychosocial, and emotional problems are prevalent. Finally, there is a higher risk of premature death among survivors of craniopharyngioma, and often this is not from tumor recurrence. It is important to consider craniopharyngioma as a chronic disease. There is no perfect treatment. The treatment has to be tailored to the individual patient to minimize dysfunction caused by tumor and treatments. So “cure” of the tumor does not mean a normal patient. The management of the patient and family needs multidisciplinary evaluation and should involve ophthalmology, endocrinology, neurosurgery, oncology, and psychology. Furthermore, it is also important to address emotional issues and social integration. PMID:26345668

  2. Institutionalization and Organizational Long-term Success

    Denise L. Fleck

    2007-05-01

    Full Text Available Institutionalization processes have an ambivalent effect on organizational long-term success. Even though they foster organizational stability and permanence, they also bring about rigidity and resistance to change. As a result, successful organizations are likely to lose their competitive advantage over time. The paper addresses this issue through the investigation of the institutionalization processes of two long-lived companies: General Electric, a firm that has been a long-term success and its rival, Westinghouse, which was broken up after eleven decades of existence. The longitudinal, multilevel analysis of firms and industry has identified two different modes of organizational institutionalization. The reactive mode gives rise to rigidity and change resistance, much like institutional theory predicts; the proactive mode, on the other hand, neutralizes those negative effects of institutionalization processes. In the reactive mode, structure predominates. In the proactive mode, agency plays a major role in organizational institutionalization, and in managing the organization’s relations with the environment, clearly contributing to environmental institutionalization.

    Long term tests of PSI membranes based on radiation-grafted FEP and ETFE films were carried out and FEP-based membranes were evaluated by monitoring the in-situ membrane area resistance measured by a current pulse method. By modifying our irradiation procedure and using the double crosslinking concept we obtain reproducible membrane cell lifetimes (in term of in-situ membrane resistance) of greater than 5000 hours at 60-65{sup o}C. Preliminary tests at 80-85{sup o}C with lifetimes of greater than 2500 demonstrate the potential long term stability of PSI proton exchange membranes based on FEP over the whole operating temperature range of low-temperature polymer electrolyte fuel cells. Radiation grafted PSI membranes based on ETFE have better mechanical properties than those of the FEP membranes. Mechanical properties are particularly important in large area cells and fuel cell stacks. ETFE membranes have been tested successfully for approximately 1000 h in a 2-cell stack (100 cm{sup 2} active area each cell). (author) 4 figs., 4 refs.

    One of the commonest forms of orthotopic bladder substitution for bladder cancer surivors, used in our institute, is the use of ileocecal segment. Sometimes, the need for Indiana pouch heterotropic continent diversion arises. Aim: To compare the long-term effect of orthotopic ileocecal bladder and heterotropic Indiana pouch following radical cystectomy in bladder cancer patients. Patients and methods: Between January 2008 and December 2011, 91 patients underwent radical cystectomy/anterior pelvic exentration and ortho topic ileocecal bladder reconstruction (61 patients) and Indiana pouch (30 patients), when orthotopic diversion could not be technically or oncologically feasible. Results: Convalescence was uneventful in most patients. All minor and major urinary leakage cases, in both diversions groups, where successfully conservatively treated. Only one patient in the ileocecal group with major urinary leak required re-exploration with successful revision of uretro-colonic anastomosis. Only one patient in the Indiana pouch group had accidentally discovered sub-centimetric stone, which was simply expelled. The overall survival proportion of ileocecal group was 100% compared to 80% in the Indiana pouch group (p < 0.001). The disease free survival proportion of ileocecal group was 90.8% compared to 80% in the Indiana pouch group (p = 0.076). Effective comparative daytime and nighttime urinary continence as well as renal function deterioration were not statistically significant between both reconstruction types. Conclusion: Both ileocecal bladder and Indiana pouch are safe procedures in regard to long-term effects over kidney function following radical cystectomy

  5. Toward a comprehensive long term nicotine policy.

    Global tobacco deaths are high and rising. Tobacco use is primarily driven by nicotine addiction. Overall tobacco control policy is relatively well agreed upon but a long term nicotine policy has been less well considered and requires further debate. Reaching consensus is important because a nicotine policy is integral to the target of reducing tobacco caused disease, and the contentious issues need to be resolved before the necessary political changes can be sought. A long term and comprehensive nicotine policy is proposed here. It envisages both reducing the attractiveness and addictiveness of existing tobacco based nicotine delivery systems as well as providing alternative sources of acceptable clean nicotine as competition for tobacco. Clean nicotine is defined as nicotine free enough of tobacco toxicants to pass regulatory approval. A three phase policy is proposed. The initial phase requires regulatory capture of cigarette and smoke constituents liberalising the market for clean nicotine; regulating all nicotine sources from the same agency; and research into nicotine absorption and the role of tobacco additives in this process. The second phase anticipates clean nicotine overtaking tobacco as the primary source of the drug (facilitated by use of regulatory and taxation measures); simplification of tobacco products by limitation of additives which make tobacco attractive and easier to smoke (but tobacco would still be able to provide a satisfying dose of nicotine). The third phase includes a progressive reduction in the nicotine content of cigarettes, with clean nicotine freely available to take the place of tobacco as society's main nicotine source.

  6. Long term ground movement of TRISTAN synchrotron

    Endo, K.; Ohsawa, Y.; Miyahara, M.

    1989-01-01

    The long term ground movement is estimated through the geological survey before a big accelerator is planned. For the case of TRISTAN-MR (main ring), its site was surveyed to reflect the underground information to the building prior to the construction. The movement of the synchrotron magnet mainly results from the structure of the tunnel. If an individual movement of the magnet exceeds a certain threshold limit, it gives a significant effect on the particle behavior in a synchrotron. Height of the quadrupole magnets were observed periodically during past two years at the TRISTAN-MR and their height differences along the 3 km circumference of the accelerator ring were decomposed into the Fourier components depicting the causes of the movements. Results shows the movement of the tunnel foundation which was also observed by the simultaneous measurement of both magnets and fiducial marks on the tunnel wall. The long term movement of the magnets is summarized with the geological survey prior to construction. 1 ref., 6 figs., 1 tab

    Rothrock, Michael J; Vanotti, Matias B; Szögi, Ariel A; Gonzalez, Maria Cruz Garcia; Fujii, Takao

    2011-10-01

    Deposit of useful microorganisms in culture collections requires long-term preservation and successful reactivation techniques. The goal of this study was to develop a simple preservation protocol for the long-term storage and reactivation of the anammox biomass. To achieve this, anammox biomass was frozen or lyophilized at two different freezing temperatures (-60°C and in liquid nitrogen (-200°C)) in skim milk media (with and without glycerol), and the reactivation of anammox activity was monitored after a 4-month storage period. Of the different preservation treatments tested, only anammox biomass preserved via freezing in liquid nitrogen followed by lyophilization in skim milk media without glycerol achieved stoichiometric ratios for the anammox reaction similar to the biomass in both the parent bioreactor and in the freshly harvested control treatment. A freezing temperature of -60°C alone, or in conjunction with lyophilization, resulted in the partial recovery of the anammox bacteria, with an equal mixture of anammox and nitrifying bacteria in the reactivated biomass. To our knowledge, this is the first report of the successful reactivation of anammox biomass preserved via sub-zero freezing and/or lyophilization. The simple preservation protocol developed from this study could be beneficial to accelerate the integration of anammox-based processes into current treatment systems through a highly efficient starting anammox biomass.

    Document available in abstract form only. Full text of publication follows: Long term memory of repositories is required by safety, reversibility and social expectations. Thus Andra has implemented since 2010 a long-term memory project to reinforce and diversify its current arrangements in this field, as well as to explore opportunities to extend memory keeping over thousands years. The project includes opportunity studies of dedicated facilities. The 'Ecotheque' and 'Geotheque' projects contribute to memory respectively through environmental and geological samples preservation. The options of creating (i) an archive centre for Andra's interim and permanent archives, (ii) an artist center to study the contribution of arts to memory preservation, (iii) a museum of radioactive waste disposal history and technology (radium industry..., sea disposal, current solutions...) are considered. Other studies provided by the project examine our heritage. This includes the continuity of languages and symbolic systems, the continuity of writing and engraving methods, the archaeology of landscapes (memory of the earths evolution, multi-century memory of industrial and agricultural landscapes), the archaeology practices (how might a future archaeologist be interested in our current activity?), the preservation of historical sites and industrial memory, the continuity of institutional organizations, the memory and history of science evolution as well as broad history

  10. Long term creep behavior of concrete

    Kennedy, T.W.

    1975-01-01

    This report presents the findings of an experimental investigation to evaluate the long term creep behavior of concrete subjected to sustained uniaxial loads for an extended period of time at 75 0 F. The factors investigated were (1) curing time (90, 183, and 365 days); (2) curing history (as-cast and air-dried); and (3) uniaxial stress (600 and 2400 psi). The experimental investigation applied uniaxial compressive loads to cylindrical concrete specimens and measured strains with vibrating wire strain gages that were cast in the concrete specimen along the axial and radial axes. Specimens cured for 90 days prior to loading were subjected to a sustained load for a period of one year, at which time the loads were removed; the specimens which were cured for 183 or 365 days, however, were not unloaded and have been under load for 5 and 4.5 years, respectively. The effect of each of the above factors on the instantaneous and creep behavior is discussed and the long term creep behavior of the specimens cured for 183 or 365 days is evaluated. The findings of these evaluations are summarized. (17 figures, 10 tables) (U.S.)

  11. Sleep facilitates long-term face adaptation.

    Ditye, Thomas; Javadi, Amir Homayoun; Carbon, Claus-Christian; Walsh, Vincent

    2013-10-22

    Adaptation is an automatic neural mechanism supporting the optimization of visual processing on the basis of previous experiences. While the short-term effects of adaptation on behaviour and physiology have been studied extensively, perceptual long-term changes associated with adaptation are still poorly understood. Here, we show that the integration of adaptation-dependent long-term shifts in neural function is facilitated by sleep. Perceptual shifts induced by adaptation to a distorted image of a famous person were larger in a group of participants who had slept (experiment 1) or merely napped for 90 min (experiment 2) during the interval between adaptation and test compared with controls who stayed awake. Participants' individual rapid eye movement sleep duration predicted the size of post-sleep behavioural adaptation effects. Our data suggest that sleep prevented decay of adaptation in a way that is qualitatively different from the effects of reduced visual interference known as 'storage'. In the light of the well-established link between sleep and memory consolidation, our findings link the perceptual mechanisms of sensory adaptation--which are usually not considered to play a relevant role in mnemonic processes--with learning and memory, and at the same time reveal a new function of sleep in cognition.

  12. Sexual and social competition: broadening perspectives by defining female roles.

    Rubenstein, Dustin R

    2012-08-19

    Males figured more prominently than females in Darwin's view of sexual selection. He considered female choice of secondary importance to male-male competition as a mechanism to explain the evolution of male ornaments and armaments. Fisher later demonstrated the importance of female choice in driving male trait evolution, but his ideas were largely ignored for decades. As sexual selection came to embrace the notions of parent-offspring and sexual conflict, and experimental tests of female choice showed promise, females began to feature more prominently in the framework of sexual selection theory. Recent debate over this theory has centred around the role of females, not only over the question of choice, but also over female-female competition. Whereas some have called for expanding the sexual selection framework to encompass all forms of female-female competition, others have called for subsuming sexual selection within a broader framework of social selection, or replacing it altogether. Still others have argued for linking sexual selection more clearly to other evolutionary theories such as kin selection. Rather than simply debating terminology, we must take a broader view of the general processes that lead to trait evolution in both sexes by clearly defining the roles that females play in the process, and by focusing on intra- and inter-sexual interactions in males and females.

    2005-01-01

    either stored in small vials or spiked to polyester Salivette tampons before analysis for cortisol using Spectria RIA kits. The effects of storage were evaluated by a linear regression model (mixed procedure) on a logarithmic scale. No effects on cortisol concentrations were found after storage of saliva......The measurement of salivary cortisol provides a simple, non-invasive, and stress-free measure frequently used in studies of the hypothalamic-pituitary-adrenal axis activity. In research projects, samples are often required to be stored for longer periods of time either because of the protocol...... of the project or because of lack of funding for analysis. The aim of the present study was to explore the effects of long-term storage of samples on the amounts of measurable cortisol. Ten pools of saliva were collected on polyester Salivette tampons from five subjects. After centrifugation the samples were...

    Discussion of the design, fabrication and testing of a 225-cu ft spherical cryogenic storage system for long-term subcritical applications under zero-g conditions in storing subcritical cryogens for space vehicle propulsion systems. The insulation system design, the analytical methods used, and the correlation between the performance test results and analytical predictions are described. The best available multilayer insulation materials and state-of-the-art thermal protection concepts were applied in the design, providing a boiloff rate of 0.152 lb/hr, or 0.032% per day, and an overall heat flux of 0.066 Btu/sq ft hr based on a 200 sq ft surface area. A six to eighteen month cryogenic storage is provided by this system for space applications.

  15. Long-term control of root growth

    Burton, Frederick G.; Cataldo, Dominic A.; Cline, John F.; Skiens, W. Eugene

    1992-05-26

    A method and system for long-term control of root growth without killing the plants bearing those roots involves incorporating a 2,6-dinitroaniline in a polymer and disposing the polymer in an area in which root control is desired. This results in controlled release of the substituted aniline herbicide over a period of many years. Herbicides of this class have the property of preventing root elongation without translocating into other parts of the plant. The herbicide may be encapsulated in the polymer or mixed with it. The polymer-herbicide mixture may be formed into pellets, sheets, pipe gaskets, pipes for carrying water, or various other forms. The invention may be applied to other protection of buried hazardous wastes, protection of underground pipes, prevention of root intrusion beneath slabs, the dwarfing of trees or shrubs and other applications. The preferred herbicide is 4-difluoromethyl-N,N-dipropyl-2,6-dinitro-aniline, commonly known as trifluralin.

  16. Long term performance of radon mitigation systems

    Prill, R.; Fisk, W.J.

    2002-01-01

    Researchers installed radon mitigation systems in 12 houses in Spokane, Washington and Coeur d'Alene, Idaho during the heating season 1985--1986 and continued to monitor indoor radon quarterly and annually for ten years. The mitigation systems included active sub-slab ventilation, basement over-pressurization, and crawlspace isolation and ventilation. The occupants reported various operational problems with these early mitigation systems. The long-term radon measurements were essential to track the effectiveness of the mitigation systems over time. All 12 homes were visited during the second year of the study, while a second set 5 homes was visited during the fifth year to determine the cause(s) of increased radon in the homes. During these visits, the mitigation systems were inspected and measurements of system performance were made. Maintenance and modifications were performed to improve system performance in these homes

  17. Rising Long-term Interest Rates

    Hallett, Andrew Hughes

    Rather than chronicle recent developments in European long-term interest rates as such, this paper assesses the impact of increases in those interest rates on economic performance and inflation. That puts us in a position to evaluate the economic pressures for further rises in those rates......, the first question posed in this assignment, and the scope for overshooting (the second question), and then make some illustrative predictions of future interest rates in the euro area. We find a wide range of effects from rising interest rates, mostly small and mostly negative, focused on investment...... till the emerging European recovery is on a firmer basis and capable of overcoming increases in the cost of borrowing and shrinking fiscal space. There is also an implication that worries about rising/overshooting interest rates often reflect the fact that inflation risks are unequally distributed...

  18. Prediction of long-term creep curves

    Oikawa, Hiroshi; Maruyama, Kouichi

    1992-01-01

    This paper aims at discussing how to predict long-term irradiation enhanced creep properties from short-term tests. The predictive method based on the θ concept was examined by using creep data of ferritic steels. The method was successful in predicting creep curves including the tertiary creep stage as well as rupture lifetimes. Some material constants involved in the method are insensitive to the irradiation environment, and their values obtained in thermal creep are applicable to irradiation enhanced creep. The creep mechanisms of most engineering materials definitely change at the athermal yield stress in the non-creep regime. One should be aware that short-term tests must be carried out at stresses lower than the athermal yield stress in order to predict the creep behavior of structural components correctly. (orig.)

  19. Hanford grout: predicting long-term performance

    Sewart, G.H.; Mitchell, D.H.; Treat, R.L.; McMakin, A.H.

    1987-01-01

    Grouted disposal is being planned for the low-level portion of liquid radioactive wastes at the Hanford site in Washington state. The performance of the disposal system must be such that it will protect people and the environment for thousands of years after disposal. To predict whether a specific grout disposal system will comply with existing and foreseen regulations, a performance assessment (PA) is performed. Long-term PAs are conducted for a range of performance conditions. Performance assessment is an inexact science. Quantifying projected impacts is especially difficult when only scant data exist on the behavior of certain components of the disposal system over thousands of years. To develop defensible results, we are honing the models and obtaining experimental data. The combination of engineered features and PA refinements is being used to ensure that Hanford grout will meet its principal goal: to protect people and the environment in the future

  20. The discovery of long-term potentiation.

    Lømo, Terje

    2003-04-29

    This paper describes circumstances around the discovery of long-term potentiation (LTP). In 1966, I had just begun independent work for the degree of Dr medicinae (PhD) in Per Andersen's laboratory in Oslo after an eighteen-month apprenticeship with him. Studying the effects of activating the perforant path to dentate granule cells in the hippocampus of anaesthetized rabbits, I observed that brief trains of stimuli resulted in increased efficiency of transmission at the perforant path-granule cell synapses that could last for hours. In 1968, Tim Bliss came to Per Andersen's laboratory to learn about the hippocampus and field potential recording for studies of possible memory mechanisms. The two of us then followed up my preliminary results from 1966 and did the experiments that resulted in a paper that is now properly considered to be the basic reference for the discovery of LTP.

    Fibroids (leiomyoma) are the most frequent benign tumors of the uterus during female reproductive age. In the case of clinical symptoms, uterine artery embolization (UAE) is a well established treatment option for symptomatic fibroids, resulting in promising long-term results. In order to estimate long-term success after UAE, reduction of fibroids and uterus volume is less important than complete improvement and disappearance of fibroid-related symptoms. In addition to a high technical success rate and a low perioperative complication rate, UAE results in high short-term and long-term patient satisfaction (>87%) and improvement of symptoms (>81%). Candidates for UAE should be informed about potential reinterventions in terms of repeated UAE (up to 18% of cases) or surgical treatment options. (orig.) [German] Myome sind die haeufigsten gutartigen soliden Tumoren des weiblichen Genitaltrakts im reproduktiven Alter. Bei klinischen Beschwerden stellt die Uterusarterienembolisation (UAE) zur Therapie des symptomatischen Uterus myomatosus einen fest etabliertes Verfahren dar, das mit viel versprechenden Langzeitergebnissen aufwarten kann. Im Vordergrund der Abschaetzung eines lang andauernden Therapieerfolgs nach UAE stehen weniger die Volumenreduktion eines dominanten Myoms bzw. des gesamten Uterus nach der Behandlung, sondern vielmehr die Besserung oder das voellige Verschwinden der von der Patientin initial vor der UAE angegebenen (myombedingten) Beschwerden. Neben einer hohen technischen Erfolgsrate und geringen perioperativen Komplikationsrate fuehrt die fachkundig durchgefuehrte UAE sowohl im Kurz- als auch Langzeitverlauf zu einem hohen Mass an Patientenzufriedenheit (>87%), verbunden mit einer deutlichen Symptombesserung (>81%). Ueber eine Reintervention (in bis zu ca. 18% der Faelle) im Sinne einer erneuten UAE oder einer operativen Massnahme sollten die Patientinnen allerdings im Vorfeld aufgeklaert werden. (orig.)

  5. Long term radiological impact of thorium extraction

    Menard, S.; Schapira, J.P.

    1995-01-01

    Thorium extraction produces a certain amount of radioactive wastes. Potential long term radiological impact of these residues has been calculated using the recent ICRP-68 ingestion dose factors in connection with the computing code DECAY, developed at Orsay and described in this work. This code solves the well known Bateman's equations which govern the time dependence of a set of coupled radioactive nuclei. Monazites will be very likely the minerals to be exploited first, in case of an extensive use of thorium as nuclear fuel. Because monazites contain uranium as well, mining residues will contain not only the descendants of 232 Th and a certain proportion of non-extracted thorium (taken here to be 5%), but also this uranium, if left in the wastes for economical reasons. If no uranium would be present at all in the mineral, the potential radiotoxicity would strongly decrease in approximately 60 years, at the pace of the 5.8 years period of 228 Ra, which becomes the longest-lived radionuclide of the 4n radioactive family in the residues. Moreover, there is no risk due to radon exhalation, because of the very short period of 220 Rn. These significant differences between uranium and thorium mining have to be considered in view of some estimated long term real radiological impacts due to uranium residues, which could reach a value of the order of 1 mSv/year, the dose limit recommended for the public by the recent ICRP-60.

    The U.S. Department of Energy (DOE) is responsible for managing vast amounts of information documenting historical and current operations. This information is critical to the operations of the DOE Office of Legacy Management. Managing legacy records and information is challenging in terms of accessibility and changing technology. The Office of Legacy Management is meeting these challenges by making records and information management an organizational priority. The Office of Legacy Management mission is to manage DOE post-closure responsibilities at former Cold War weapons sites to ensure the future protection of human health and the environment. These responsibilities include environmental stewardship and long-term preservation and management of operational and environmental cleanup records associated with each site. A primary organizational goal for the Office of Legacy Management is to 'Preserve, Protect, and Share Records and Information'. Managing records for long-term preservation is an important responsibility. Adequate and dedicated resources and management support are required to perform this responsibility successfully. Records tell the story of an organization and may be required to defend an organization in court, provide historical information, identify lessons learned, or provide valuable information for researchers. Loss of records or the inability to retrieve records because of poor records management processes can have serious consequences and even lead to an organisation's downfall. Organizations must invest time and resources to establish a good records management program because of its significance to the organization as a whole. The Office of Legacy Management will continue to research and apply innovative ways of doing business to ensure that the organization stays at the forefront of effective records and information management. DOE is committed to preserving records that document our nation's Cold War legacy, and the

  8. PEBS. Long-term performance of engineered barrier systems

    Wieczorek, Klaus; Czaikowski, Oliver; Miehe, Ruediger

    2014-12-15

    The evolution of the engineered barrier system (EBS) of geological repositories for radioactive waste has been the subject of many national and international research programmes. The emphasis of the research activities was on the elaboration of a detailed understanding of the complex THMC processes, which are expected to evolve in the early post closure period in the near field. From the perspective of radiological long-term safety, an in-depth understanding of these coupled processes is of great significance, because the evolution of the EBS during the early post-closure phase may have a non-negligible impact on the radiological safety functions at the time when the canisters breach. Unexpected process interactions during the resaturation phase could impair the safety-relevant parameters in the EBS (e. g. swelling pressure, hydraulic conductivity, diffusivity).

    To determine the long-term outcomes of a prospective cohort of 20 patients who had nasopharyngectomy using an open partial-maxillectomy approach. A prospective cohort study of the surgical outcomes of patients with recurrent T1 (rT1) and rT2 nasopharyngeal carcinoma recurrence. There were 14 male and six female patients. The mean age was 49 years. The mean duration of follow-up was 60.4 months. All of the surgical margins were free of malignancy. Ten patients (50%) developed recurrences. The 5-year local control rate, disease-free, disease-specific, and overall survivals were 70%, 48.9%, 70.2%, and 66.7%, respectively. There were no major intraoperative complications. The most common morbidity was pain. The median length of hospitalization was 4 days. Early local recurrence of nasopharyngeal carcinoma can be treated surgically using a partial maxillectomy approach. The long-term outcomes are similar to nasopharyngectomy performed using the more common approaches. 4.

    1998-01-01

    A retrospective study was performed in 41 patients, in chronic hemodialysis with severe hyperparathyroidism (HPT), who underwent surgery during time period from 1985 to 1997. 22 females, 19 males, aged 50 and 14 years, with PTHI 1345 and 604 pg/ml were followed up 32 and 22 months. Three surgical methods we evaluated: group I) total para thyroidectomy(PTX) with Implants(n=24); group II) subtotal PTX(n=14) and group III) total PTX(n=3). It considered recurrence of HPT when PTH levels were higher than upper range of normal, after 6 months post surgery. persistence was defined when there was no standardization of PTH levels. In group I, 9 patients had normal parathyroid function, 7 had persistent hypoparathyroidism and had hyperparathyroidism (7 recurrences). Group II patients had parathyroid over function in 5 cases (4 persistence s), 5 were normal and 4 hypoparathyroidism. All patients of the third group had hypoparathyroidism. Long term normalization of parathyroid gland activity was achieved in one third of troduccion patients (34,1%) whereas 34,1% permanent hypoparathyroidism and 31,8% hyperparathyroidism. It found no differences in recurrence and histological subtype of parathyroid gland in the different groups. In conclusion, similar long term clinical results were obtained with the different groups. The surgical ideal treatment is controversial. We think that in the long run, the evolution of parathyroid status is mostly influenced by the persistence of uremic state rather than the type of surgery performed [es

    Background. We report long-term outcomes in adult patients with craniopharyngioma following surgery and radiation therapy (RT). Material and methods. Fifty-three patients treated with RT (median, 50 Gy in 25 fractions) between 1980 and 2009 with pathologically confirmed craniopharyngioma were reviewed (53% solid and 47% cystic/solid). The median age was 53 years (range, 22-76), 53% were female, 83% were sub-totally resected, 6% were gross totally resected and 11% had a biopsy and/or cyst aspiration alone. RT was delivered adjuvantly in 53% of patients as opposed to salvage intent upon progression. Results. Median follow-up was seven years (86 months, range, 8-259). The 5- and 10-year progression-free survival (PFS) rates were 85% and 69%, overall survival (OS) rates were 76% and 70%, and cause-specific survival (CSS) rates were both 88%, respectively. Both univariable and multivariable analysis identified age ( 2 surgeries prior to RT (p =0.01). Neither the intent of radiation or tumor type (cystic vs. solid/cystic) were prognostic or predictive. New endocrinopathies and visual dysfunction were observed in 53% and 17% of patients post-surgery, and in 11% and 6% post-RT, respectively. Conclusion. We report long-term favorable PFS, CSS and OS for craniopharyngioma post-RT. We observe age as a significant prognostic factor, however, timing of radiation was not

  13. Robotics for Long-Term Monitoring

    Shahin, Sarkis; Duran, Celso

    2002-01-01

    While long-term monitoring and stewardship means many things to many people, DOE has defined it as The physical controls, institutions, information, and other mechanisms needed to ensure protection of people and the environment at sites where DOE has completed or plans to complete cleanup (e.g., landfill closures, remedial actions, and facility stabilization). Across the United States, there are thousands of contaminated sites with multiple contaminants released from multiple sources where contaminants have transported and commingled. The U.S. government and U.S. industry are responsible for most of the contamination and are landowners of many of these contaminated properties. These sites must be surveyed periodically for various criteria including structural deterioration, water intrusion, integrity of storage containers, atmospheric conditions, and hazardous substance release. The surveys, however, are intrusive, time-consuming, and expensive and expose survey personnel to radioactive contamination. In long-term monitoring, there's a need for an automated system that will gather and report data from sensors without costly human labor. In most cases, a SCADA (Supervisory Control and Data Acquisition) unit is used to collect and report data from a remote location. A SCADA unit consists of an embedded computer with data acquisition capabilities. The unit can be configured with various sensors placed in different areas of the site to be monitored. A system of this type is static, i.e., the sensors, once placed, cannot be moved to other locations within the site. For those applications where the number of sampling locations would require too many sensors, or where exact location of future problems is unknown, a mobile sensing platform is an ideal solution. In many facilities that undergo regular inspections, the number of video cameras and air monitors required to eliminate the need for human inspections is very large and far too costly.

  16. A Literature Review on the Experience of Long-Term Mental Illness.

    Collier, Elizabeth; Grant, Maria J

    2018-06-01

    To illuminate long-term experiences of mental illness from both research and autobiographical accounts. A literature review of English-language papers, 1950-2014, relating to the experience of long-term mental illness indexed in AgeInfo, AMED, ASSIA, British Nursing Index (BNI), CINAHL, MEDLINE, PsycEXTRA, and PsychINFO. Twenty-five research papers and nine autobiographic accounts met the review criteria. Thematic analysis revealed nine themes: fear, explanation seeking, stigma, disability, coping strategies, control, support, change and learning, and life history. Specific gaps of note relate to age differences, acknowledgement of longevity of mental illnesses, and different cultural perspectives. Research Implications: There is an absence of longitudinal studies focused on experiences of long-term mental illness. The considerable length-of-time implicated in the experiences suggests that more individual life experience rather than illness focused studies are needed, enabling a holistic understanding. This includes studies from cultures other than the Western world. Greater transparency is needed in justifying age inclusions or passive exclusion of older peoples' perspectives. Knowledge of long-term mental illness experiences is of great importance to mental health practitioners. Evidence-based services cannot be provided if we do not have an holistic understanding of long-term mental illness. Social Implications: This review questions our ability to provide effective support for those experiencing long-term mental illness, in particular older people and different cultural perspectives. There appear to be no literature reviews that focus on the individual experience of long-term mental illness. It highlights the surprisingly small number of research studies available to inform mental health practitioners.

    Batra Puneet

    2006-03-01

    Full Text Available Mandibular distraction osteogenesis has become a popular surgical modality due to its many advantages over conventional orthognathic surgical procedures. However, in spite of the technique having been used for over 15 years, no concrete long term results are available regarding the stability of results. We discuss the various studies which have reported either in favour or against the stablility of results after distraction. We report a series of 6 cases (3 unilateral and 3 bilateral distraction where distraction was carried out before puberty and followed them up to seven years after removal of distractors. This case series shows that results achieved by distraction osteogenesis are unstable or best unpredictable with respect to producing a permanent size increase in the mandible. The role of the distraction osteogenesis in overcoming the pterygomassetric sling is questionable. We suggest a multicenter study with adequate patient numbers treated with a similar protocol and documented after growth cessation to have meaningful conclusions on the debate of distraction osteogenesis versus orthognathic surgery.

  1. [Perioperative management of long-term medication].

    Vogel Kahmann, I; Ruppen, W; Lurati Buse, G; Tsakiris, D A; Bruggisser, M

    2011-01-01

    Anesthesiologists and surgeons are increasingly faced with patients who are under long-term medication. Some of these drugs can interact with anaesthetics or anaesthesia and/or surgical interventions. As a result, patients may experience complications such as bleeding, ischemia, infection or severe circulatory reactions. On the other hand, perioperative discontinuation of medication is often more dangerous. The proportion of outpatient operations has increased dramatically in recent years and will probably continue to increase. Since the implementation of DRGs (pending in Switzerland, introduced in Germany for some time), the patient enters the hospital the day before operation. This means that the referring physician as well as anesthesiologists and surgeons at an early stage must deal with issues of perioperative pharmacotherapy. This review article is about the management of the major drug classes during the perioperative period. In addition to cardiac and centrally acting drugs and drugs that act on hemostasis and the endocrine system, special cases such as immunosuppressants and herbal remedies are mentioned.

  2. Long term agreements energy efficiency. Progress 1999

    NONE

    2000-11-01

    Long Term Agreements (LTAs) on energy efficiency have been contracted with various business sectors since 1992, as part of energy conservation policy: industrial sectors, commercial services, agrarian sectors and non-profit services. LTAs are voluntary agreements between a specific sector and the Minister of Economic Affairs. In some cases, the Minister of Agriculture, Nature Management and Fisheries is also involved. The sector commits to an effort to improve energy efficiency by a particular percentage within an agreed period. As at 31 December 1999, a total of 29 LTAs had been contracted with industrial sectors and 14 with non-industrial ones. This report describes the progress of the LTAs in 1999. It reviews the energy efficiency improvements realised through the LTAs, both overall and in each individual sector. The aim is to make the efforts and results in the various sectors accessible to the general public. Appendix 1 describes the positioning of the LTA instrument. This Appendix provides and insight into the position of the LTAs within the overall set of policy instruments. It also covers the subsidy schemes and fiscal instruments that support the LTAs, the relationships between LTAs and environmental policy and new developments relating to the LTAs in the years ahead. Appendices 2 to 6 contain the reports on the LTAs and a list of abbreviations (Appendix 7)

    Full Text Available INTRODUCTION: Neuroparacoccidioidomycosis (NPCM is a term used to describe the invasion of the central nervous system by the pathogenic fungus Paracoccidioides brasiliensis. NPCM has been described sporadically in some case reports and small case series, with little or no focus on treatment outcome and long-term follow-up. METHODS: All patients with NPCM from January 1991 to December 2006 were analyzed and were followed until December 2009. RESULTS: Fourteen (3.8% cases of NPCM were identified out of 367 patients with paracoccidioidomycosis (PCM. A combination of oral fluconazole and sulfamethoxazole/trimethoprim (SMZ/TMP was the regimen of choice, with no documented death due to Paracoccidioides brasiliensis infection. Residual neurological deficits were observed in 8 patients. Residual calcification was a common finding in neuroimaging follow-up. CONCLUSIONS: All the patients in this study responded positively to the association of oral fluconazole and sulfamethoxazole/trimethoprim, a regimen that should be considered a treatment option in cases of NPCM. Neurological sequela was a relatively common finding. For proper management of these patients, anticonvulsant treatment and physical therapy support were also needed.

  4. Long term prospects for world gas trade

    Linder, P.T.

    1991-01-01

    Results are presented from a world gas trade model used to forecast long term gas markets. Assumptions that went into the model are described, including the extent of current proven gas reserves, production ratios, total energy and gas demand, gas supply cost curves for each producing country, available gas liquefaction and transportation facilities, and liquefied natural gas (LNG) shipping costs. The results indicate that even with generally very low supply costs for most gas producing basins, gas trade will continue to be restricted by the relatively high cost of transportation, whether by pipeline or tanker. As a consequence, future gas trade will tend to be regionally oriented. United States gas imports will come mostly from Canada, Venezuela, and Mexico; Western Europe will largely be supplied by the Soviet Union and Africa, and Japan's requirements will generally be met by Pacific Rim producers. Although the Middle East has vast quantities of gas reserves, its export growth will continue to be hampered by its remote location from major markets. 16 figs

  5. Long term results of childhood dysphonia treatment.

    Mackiewicz-Nartowicz, Hanna; Sinkiewicz, Anna; Bielecka, Arleta; Owczarzak, Hanna; Mackiewicz-Milewska, Magdalena; Winiarski, Piotr

    2014-05-01

    The aim of this study was to assess the long term results of treatment and rehabilitation of childhood dysphonia. This study included a group of adolescents (n=29) aged from 15 to 20 who were treated due to pediatric hyperfunctional dysphonia and soft vocal fold nodules during their pre-mutational period (i.e. between 5 and 12 years of age). The pre-mutational therapy was comprised of proper breathing pattern training, voice exercises and psychological counseling. Laryngostroboscopic examination and perceptual analysis of voice were performed in each patient before treatment and one to four years after mutation was complete. The laryngostroboscopic findings, i.e. symmetry, amplitude, mucosal wave and vocal fold closure, were graded with NAPZ scale, and the GRBAS scale was used for the perceptual voice analysis. Complete regression of the childhood dysphonia was observed in all male patients (n=14). Voice disorders regressed completely also in 8 out of 15 girls, but symptoms of dysphonia documented on perceptual scale persisted in the remaining seven patients. Complex voice therapy implemented in adolescence should be considered as either the treatment or preventive measure of persistent voice strain, especially in girls.

  6. Long-term data storage in diamond

    Dhomkar, Siddharth; Henshaw, Jacob; Jayakumar, Harishankar; Meriles, Carlos A.

    2016-01-01

    The negatively charged nitrogen vacancy (NV−) center in diamond is the focus of widespread attention for applications ranging from quantum information processing to nanoscale metrology. Although most work so far has focused on the NV− optical and spin properties, control of the charge state promises complementary opportunities. One intriguing possibility is the long-term storage of information, a notion we hereby introduce using NV-rich, type 1b diamond. As a proof of principle, we use multicolor optical microscopy to read, write, and reset arbitrary data sets with two-dimensional (2D) binary bit density comparable to present digital-video-disk (DVD) technology. Leveraging on the singular dynamics of NV− ionization, we encode information on different planes of the diamond crystal with no cross-talk, hence extending the storage capacity to three dimensions. Furthermore, we correlate the center’s charge state and the nuclear spin polarization of the nitrogen host and show that the latter is robust to a cycle of NV− ionization and recharge. In combination with super-resolution microscopy techniques, these observations provide a route toward subdiffraction NV charge control, a regime where the storage capacity could exceed present technologies.

  8. Long-term predictions using natural analogues

    Ewing, R.C.

    1995-01-01

    One of the unique and scientifically most challenging aspects of nuclear waste isolation is the extrapolation of short-term laboratory data (hours to years) to the long time periods (10 3 -10 5 years) required by regulatory agencies for performance assessment. The direct validation of these extrapolations is not possible, but methods must be developed to demonstrate compliance with government regulations and to satisfy the lay public that there is a demonstrable and reasonable basis for accepting the long-term extrapolations. Natural systems (e.g., open-quotes natural analoguesclose quotes) provide perhaps the only means of partial open-quotes validation,close quotes as well as data that may be used directly in the models that are used in the extrapolation. Natural systems provide data on very large spatial (nm to km) and temporal (10 3 -10 8 years) scales and in highly complex terranes in which unknown synergisms may affect radionuclide migration. This paper reviews the application (and most importantly, the limitations) of data from natural analogue systems to the open-quotes validationclose quotes of performance assessments

  9. Long-term effects of islet transplantation.

    Holmes-Walker, D Jane; Kay, Thomas W H

    2016-10-01

    Islet transplantation has made great progress in recent years. This is a remarkable technical feat but raises the question of what the long-term benefits and risks are for type I diabetes recipients. Graft survival continues to improve, and recent multicenter studies show that islet transplantation is particularly effective to prevent hypoglycemic events even in those who do not become insulin-independent and to achieve excellent glycemic control. Concerns include histocompatability leucocyte antigen (HLA) sensitization and other risks including from immunosuppression that islet transplantation shares with other forms of allotransplantation. Reversal of hypoglycemia unawareness and protection from severe hypoglycemia events are two of the main benefits of islet transplantation and they persist for the duration of graft function. Islet transplantation compares favorably with other therapies for those with hypoglycemia unawareness, although new technologies have not been tested head-to-head with transplantation. HLA sensitization increases with time after transplantation especially if immunosuppression is ceased and is a risk for those who may require future transplantation as well as being associated with loss of graft function.

    2016-01-01

    In this paper we describe the services that are offered by CERN for Long Term preservation of High Energy Physics (HEP) data, with the Large Hadron Collider (LHC) as a key use case. Data preservation is a strategic goal for European High Energy Physics (HEP), as well as for the HEP community worldwide and we position our work in this global content. Specifically, we target the preservation of the scientific data, together with the software, documentation and computing environment needed to process, (re-)analyse or otherwise (re-)use the data. The target data volumes range from hundreds of petabytes (PB – 10^15 bytes) to hundreds of exabytes (EB – 10^18 bytes) for a target duration of several decades. The Use Cases driving data preservation are presented together with metrics that allow us to measure how close we are to meeting our goals, including the possibility for formal certification for at least part of this work. Almost all of the services that we describe are fully generic – the exception being A...

  11. Containment long-term operational integrity

    Sammataro, R.F.

    1990-01-01

    Periodic integrated leak rate tests are required to assure that containments continue to meet allowable leakage limits. Although overall performance has been quite good to date, several major containment aging and degradation mechanisms have been identified. Two pilot plant life extension (PLEX) studies serve as models for extending the operational integrity of present containments for light-water cooled nuclear power plants in the United States. One study is for a Boiling-Water Reactor (BWR) and the second is for a Pressurized-Water Reactor (PWR). Research and testing programs for determining the ultimate pressure capacity and failure mechanisms for containments under severe loading conditions and studies for extending the life of current plants beyond the present 40-year licensed lifetime are under way. This paper presents an overview of containment designs in the United States. Also presented are a discussion of the American Society of Mechanical Engineers Boiler and Pressure Vessel Code (ASME Code) and regulatory authority requirements for the design, construction, inservice inspection, leakage testing and repair of steel and concrete containments. Findings for containments from the pilot PLEX studies and continuing containment integrity research and testing programs are discussed. The ASME Code and regulatory requirements together with recommendations from the PLEX studies and containment integrity research and testing provide a basis for continued containment long-term operational integrity.

  12. Long term results of compression sclerotherapy.

    Labas, P; Ohradka, B; Cambal, M; Reis, R; Fillo, J

    2003-01-01

    To compare the short and long term results of different techniques of compression sclerotherapy. In the past 10 years the authors treated 1622 pts due to chronic venous insufficiency. There were 3 groups of patients: 1) Pts treated by Sigg's technique using Aethoxysclerol, 2) Pts treated by Fegan's technique with Fibrovein, and 3) Pts treated by Fegan's procedure, but using a combination of both sclerosants. In all cases, the techniques of empty vein, bubble air, uninterrupted 6-week compression and forced mobilisation were used. In the group of pats. treated by Sigg's procedure, the average cure rate was 67.47% after 6 months, 60.3% after 5 years of follow-up. In Fegan's group this rate was 83.6% after 6 months and 78.54% after 5 year assessment. Statistically, significant differences were found only by the disappearance of varices and reduction of pain in favour of Fegan's technique. In the group of pts treated by Fegan's (Aethoxysclerol + Fibrovein) this rate after 5 years was 86%. The only statistically significant difference was found by the disappearance of varices in favour of Fegan's technique using a combination of 2 detergent sclerosants. Sclerotherapy is effective when properly executed in any length of vein no matter how dilated it has become. The recurrences are attributed more to inadequate technique than to the shortcoming of the procedure. Sclerotherapy is miniinvasive, with few complications, and can be repeated on out-patient basis.

  13. Transuranic waste: long-term planning

    Young, K.C.

    1985-07-01

    Societal concerns for the safe handling and disposal of toxic waste are behind many of the regulations and the control measures in effect today. Transuranic waste, a specific category of toxic (radioactive) waste, serves as a good example of how regulations and controls impact changes in waste processing - and vice versa. As problems would arise with waste processing, changes would be instituted. These changes improved techniques for handling and disposal of transuranic waste, reduced the risk of breached containment, and were usually linked with regulatory changes. Today, however, we face a greater public awareness of and concern for toxic waste control; thus, we must anticipate potential problems and work on resolving them before they can become real problems. System safety analyses are valuable aids in long-term planning for operations involving transuranic as well as other toxic materials. Examples of specific system safety analytical methods demonstrate how problems can be anticipated and resolution initiated in a timely manner having minimal impacts upon allocation of resource and operational goals. 7 refs., 1 fig

    Wilkey, D.D.; Wood, W.T.; Guenther, C.D.

    1994-01-01

    An important part of the Department of Energy (DOE) Weapons Complex Reconfiguration (WCR) Program is the development of facilities for long-term storage of plutonium. The WCR design goals are to provide storage for metals, oxides, pits, and fuel-grade plutonium, including material being held as part of the Strategic Reserve and excess material. Major activities associated with plutonium storage are sorting the plutonium inventory, material handling and storage support, shipping and receiving, and surveillance of material in storage for both safety evaluations and safeguards and security. A variety of methods for plutonium storage have been used, both within the DOE weapons complex and by external organizations. This paper discusses the advantages and disadvantages of proposed storage concepts based upon functional criteria. The concepts discussed include floor wells, vertical and horizontal sleeves, warehouse storage on vertical racks, and modular storage units. Issues/factors considered in determining a preferred design include operational efficiency, maintenance and repair, environmental impact, radiation and criticality safety, safeguards and security, heat removal, waste minimization, international inspection requirements, and construction and operational costs

  17. Scientific Understanding from Long Term Observations: Insights from the Long Term Ecological Research (LTER) Program

    Gosz, J.

    2001-12-01

    The network dedicated to Long Term Ecological Research (LTER) in the United States has grown to 24 sites since it was formed in 1980. Long-term research and monitoring are performed on parameters thatare basic to all ecosystems and are required to understand patterns, processes, and relationship to change. Collectively, the sites in the LTER Network provide opportunities to contrast marine, coastal, and continental regions, the full range of climatic gradients existing in North America, and aquatic and terrestrial habitats in a range of ecosystem types. The combination of common core areas and long-term research and monitoring in many habitats have allowed unprecedented abilities to understand and compare complex temporal and spatial dynamics associated with issues like climate change, effects of pollution, biodiversity and landuse. For example, McMurdo Dry Valley in the Antarctic has demonstrated an increase in glacier mass since 1993 which coincides with a period of cooler than normal summers and more than average snowfall. In contrast, the Bonanza Creek and Toolik Lake sites in Alaska have recorded a warming period unprecedented in the past 200 years. Nitrogen deposition effects have been identified through long-term watershed studies on biogeochemical cycles, especially at Coweeta Hydrological Lab, Harvard Forest, and the Hubbard Brook Experimental Forest. In aquatic systems, such as the Northern Temperate Lakes site, long-term data revealed time lags in effects of invaders and disturbance on lake communities. Biological recovery from an effect such as lake acidification was shown to lag behind chemical recovery. The long-term changes documented over 2 decades have been instrumental in influencing management practices in many of the LTER areas. In Puerto Rico, the Luquillo LTER demonstrated that dams obstruct migrations of fish and freshwater shrimp and water abstraction at low flows can completely obliterate downstream migration of juveniles and damage

    Dessus, Benjamin [ed.] [Centre National de la Recherche Scientifique (CNRS), 75 - Paris (France)

    2000-02-02

    This report presents the results of a workshop intending to anticipate the long term challenges, to guide better the short term power options, to understand the available political, economical and technical assumptions for the prospective world situation, to give some strategic hints on the necessary transition. Indeed, the difficult issue which the workshop tried to tackle was how should we prepare to reveal the energetic challenge of the development of the eight to ten billion inhabitants of our Planet in the next century without jeopardizing its existence. The energetic problems, a hardcore of the international preoccupation of both growth and environment, as it was recently evidenced by the climatic conference in Kyoto, have ever been the object of a particular attention on the part of General Commissariat of Plan. Thus, the commission 'Energy in 2010 - 2020' has been instituted in April 1996 in order to update the works done in 1990 - 1991 by the commission 'Energy 2010'. Soon it occurred to this new commission the task of illuminating its works by a long term (2050 - 2100) world prospective analysis of the challenges and problems linked to energy, growth and environment. In conclusion, this document tried to find answers to questions like: - which are the risks the energy consumption augmentation entail? - can we control them by appropriate urbanism and transport policies or technological innovation?. Four options for immediate action are suggested: - the energy efficiency should become a priority objective of policies; -coping with the long term challenges requires acting at present; - building the transition between governmental leadership and market; - taking profit of all the possible synergies between short and long term planning.

  19. Monitoring long-term oral corticosteroids.

    Mundell, Lewis; Lindemann, Roberta; Douglas, James

    2017-01-01

    Corticosteroids are synthetic analogues of human hormones normally produced by the adrenal cortex. They have both glucocorticoid and mineralocorticoid properties. The glucocortoid components are anti-inflammatory, immunosuppressive, anti-proliferative and vasoconstrictive. They influence the metabolism of carbohydrate and protein, in addition to playing a key role in the body's stress response. Mineralocorticoid's main significance is in the balance of salt and water concentrations. Due to the combination of these effects, corticosteroids can cause many adverse effects. Oral corticosteroids are absorbed systemically and are therefore more likely to cause adverse effects than topical or inhaled corticosteroids. Furthermore, it is assumed that greater duration of treatment will lead to a greater number of adverse effects, and therefore the most at risk group are those taking high dose, long-term oral corticosteroids (LTOC). High dose is defined as a prescription of >5 mg oral prednisolone and long term as duration of treatment >1 month (based on National Institute for Health and Care Excellence guidance for patient's 'at risk' of systemic side effects). Parameters to be monitored in primary care include weight, blood pressure, triglycerides, glucose and urea and electrolytes. From clinical experience within the general practice setting, the authors propose that these patients do not receive adequate baseline monitoring before starting corticosteroids nor are these markers monitored consistently thereafter. This project intended to evidence this claim, evaluate the adverse effect profile and improve monitoring in this patient group. The initial audit of 22 patients, within a single general practice, detected at least one documented adverse effect in 64% of patients, while 41% reported more than one adverse effect. 45% had recorded weight gain, 18% had recorded osteoporosis, 18% had at least one recorded cataract, 14% had recorded Hypertension, 14% had recorded

  20. A security/safety survey of long term care facilities.

    Acorn, Jonathan R

    2010-01-01

    What are the major security/safety problems of long term care facilities? What steps are being taken by some facilities to mitigate such problems? Answers to these questions can be found in a survey of IAHSS members involved in long term care security conducted for the IAHSS Long Term Care Security Task Force. The survey, the author points out, focuses primarily on long term care facilities operated by hospitals and health systems. However, he believes, it does accurately reflect the security problems most long term facilities face, and presents valuable information on security systems and practices which should be also considered by independent and chain operated facilities.

  1. HLW Long-term Management Technology Development

    Choi, Jong Won; Kang, C. H.; Ko, Y. K.

    2010-02-01

    Permanent disposal of spent nuclear fuels from the power generation is considered to be the unique method for the conservation of human being and nature in the present and future. In spite of spent nuclear fuels produced from power generation, based on the recent trends on the gap between supply and demand of energy, the advance on energy price and reduction of carbon dioxide, nuclear energy is expected to play a role continuously in Korea. It means that a new concept of nuclear fuel cycle is needed to solve problems on spent nuclear fuels. The concept of the advanced nuclear fuel cycle including PYRO processing and SFR was presented at the 255th meeting of the Atomic Energy Commission. According to the concept of the advanced nuclear fuel cycle, actinides and long-term fissile nuclides may go out of existence in SFR. And then it is possible to dispose of short term decay wastes without a great risk bearing. Many efforts had been made to develop the KRS for the direct disposal of spent nuclear fuels in the representative geology of Korea. But in the case of the adoption of Advanced nuclear fuel cycle, the disposal of PYRO wastes should be considered. For this, we carried out the Safety Analysis on HLW Disposal Project with 5 sub-projects such as Development of HLW Disposal System, Radwaste Disposal Safety Analysis, Feasibility study on the deep repository condition, A study on the Nuclide Migration and Retardation Using Natural Barrier, and In-situ Study on the Performance of Engineered Barriers

  2. The long-term nuclear explosives predicament

    Swahn, J.

    1992-01-01

    A scenario is described, where the production of new military fissile materials is halted and where civil nuclear power is phased out in a 'no-new orders' case. It is found that approximately 1100 tonnes of weapons-grade uranium, 233 tonnes of weapons-grade plutonium and 3795 tonnes of reactor-grade plutonium have to be finally disposed of as nuclear waste. This material could be used for the construction of over 1 million nuclear explosives. Reactor-grade plutonium is found to be easier to extract from spent nuclear fuel with time and some physical characteristics important for the construction of nuclear explosives are improved. Alternative methods for disposal of the fissile material that will avoid the long-term nuclear explosives predicament are examined. Among these methods are dilution, denaturing or transmutation of the fissile material and options for practicably irrecoverable disposal in deep boreholes, on the sea-bed, and in space. It is found that the deep boreholes method for disposal should be the primary alternative to be examined further. This method can be combined with an effort to 'forget' where the material was put. Included in the thesis is also an evaluation of the possibilities of controlling the limited civil nuclear activities in a post-nuclear world. Some surveillance technologies for a post-nuclear world are described, including satellite surveillance. In a review part of the thesis, methods for the production of fissile material for nuclear explosives are described, the technological basis for the construction of nuclear weapons is examined, including use of reactor-grade plutonium for such purposes; also plans for the disposal of spent fuel from civil nuclear power reactors and for the handling of the fissile material from dismantled warheads is described. The Swedish plan for the handling and disposal of spent nuclear fuel is described in detail. (490 refs., 66 figs., 27 tabs.)

  3. Nutritional deficit and Long Term Potentiation alterations

    2009-01-01

    Full Text Available In the present work we examined the ability of prenatally malnourished offspring to produce and maintain long-term potentiation (LTP of the perforant path/dentate granule cell synapse in freely moving rats at 15,30, and 90 days of age. Population spike amplitude (PSA was calculated from dentate field potential recordings prior to and at 15, 30, 60 min. and 3, 5, 18 and 24 h following tetanization of the perforant pathway. All animals of both malnourished and well-nourished diet groups at 15 days of age showed potentiation of PSA measures but the measures obtained from 15-day-old prenatally malnourished animals were significantly less than that of age-matched, well-nourished controls. At 30 days of age, remarkable effect of tetanization was likely observed from PSA measures for this age group followed much the same pattern. At 90 days of age, PSA measures obtained from malnourished animals decreased from pretetanization levels immediately following tetanization. At this age, however, at three hours time recordings, this measure growing up to a level which did not differ significantly from that of the control group. These results indicate that the width of tetanization induced enhancement of dentate granule cell response in preweanling rats (15-day-old animals is signifacantly affected fromgestational protein malnutrition and this trend is kept in animals tested at 30 and 90 days of age. The fact, however, that considerable limitation in LTP generation was gained from prenatally malnourished animals at 90 days of age, implying that dietary rehabilitation starting at birth is an intervention strategy not capable to imbrove the effects of the gestational stress.

  4. Perinatal respiratory infections and long term consequences

    Luciana Indinnimeo

    2015-10-01

    Full Text Available Respiratory syncytial virus (RSV is the most important pathogen in the etiology of respiratory infections in early life. 50% of children are affected by RSV within the first year of age, and almost all children become infected within two years. Numerous retrospective and prospective studies linking RSV and chronic respiratory morbidity show that RSV bronchiolitis in infancy is followed by recurrent wheezing after the acute episod. According to some authors a greater risk of wheezing in children with a history of RSV bronchiolitis would be limited to childhood, while according to others this risk would be extended into adolescence and adulthood. To explain the relationship between RSV infection and the development of bronchial asthma or the clinical pathogenetic patterns related to a state of bronchial hyperreactivity, it has been suggested that RSV may cause alterations in the response of the immune system (immunogenic hypothesis, activating directly mast cells and basophils and changing the pattern of differentiation of immune cells present in the bronchial tree as receptors and inflammatory cytokines. It was also suggested that RSV infection can cause bronchial hyperreactivity altering nervous airway modulation, acting on nerve fibers present in the airways (neurogenic hypothesis.The benefits of passive immunoprophylaxis with palivizumab, which seems to represent an effective approach in reducing the sequelae of RSV infection in the short- and long-term period, strengthen the implementation of prevention programs with this drug, as recommended by the national guidelines of the Italian Society of Neonatology. Proceedings of the 11th International Workshop on Neonatology and Satellite Meetings · Cagliari (Italy · October 26th-31st, 2015 · From the womb to the adultGuest Editors: Vassilios Fanos (Cagliari, Italy, Michele Mussap (Genoa, Italy, Antonio Del Vecchio (Bari, Italy, Bo Sun (Shanghai, China, Dorret I.

  8. Exploration of life experiences of positive growth in long-term childhood cancer survivors.

    Kim, Yoonjung

    2017-10-01

    The aim of this study was to explore experiences of positive growth in long-term childhood cancer survivors, from their perspective. Fifteen long-term survivors of childhood cancer provided descriptions of their experiences. Data were collected through face-to-face interviews and the analysis was based on Giorgi's phenomenological research method. The analysis of positive growth experienced by long-term childhood cancer survivors revealed three themes: self-directed life, normalcy in life, and inner maturity. Long-term survivors defined positive growth as a successful transition to a self-satisfactory life based on motivation acquired through their cancer experience and on subjective goal-setting, as well as becoming cancer-free and living a normal life within society. They seemed to have acquired optimistic, flexible, active attitudes toward life while demonstrating profound gratefulness and consideration of people around them, as well as prudent approaches to health. The findings of this study verified that long-term survivors of childhood cancer have grown positively due to their negative past experience. We expect these findings to contribute to the development of programs that promote positive growth in long-term childhood cancer survivors. Copyright © 2017 Elsevier Ltd. All rights reserved.

  9. A retrospective cost-analysis of additional homeopathic treatment in Germany: Long-term economic outcomes

    Ostermann, Julia K.; Witt, Claudia M.; Reinhold, Thomas

    2017-01-01

    Objectives This study aimed to provide a long-term cost comparison of patients using additional homeopathic treatment (homeopathy group) with patients using usual care (control group) over an observation period of 33 months. Methods Health claims data from a large statutory health insurance company were analysed from both the societal perspective (primary outcome) and from the statutory health insurance perspective (secondary outcome). To compare costs between patient groups, homeopathy and control patients were matched in a 1:1 ratio using propensity scores. Predictor variables for the propensity scores included health care costs and both medical and demographic variables. Health care costs were analysed using an analysis of covariance, adjusted for baseline costs, between groups both across diagnoses and for specific diagnoses over a period of 33 months. Specific diagnoses included depression, migraine, allergic rhinitis, asthma, atopic dermatitis, and headache. Results Data from 21,939 patients in the homeopathy group (67.4% females) and 21,861 patients in the control group (67.2% females) were analysed. Health care costs over the 33 months were 12,414 EUR [95% CI 12,022–12,805] in the homeopathy group and 10,428 EUR [95% CI 10,036–10,820] in the control group (phomeopathy: EUR 6,289 [6,118–6,460]; control: EUR 5,498 [5,326–5,670], phomeopathy: EUR 1,794 [1,770–1,818]; control: EUR 1,438 [1,414–1,462], phomeopathy patients generated higher costs than control patients. Conclusion The analysis showed that even when following-up over 33 months, there were still cost differences between groups, with higher costs in the homeopathy group. PMID:28915242

  10. Long-Term Planning in Restructured Power Systems

    Botterud, Audun

    2003-01-01

    This thesis describes the development of three decision support models for long-term investment planning in restructured power systems. The model concepts address the changing conditions for the electric power industry, with the introduction of more competitive markets, higher uncertainty and less centralised planning. Under these circumstances there is an emerging need for new planning models, also for analyses of the power system in a long-term perspective. The thesis focuses particularly on how dynamic and stochastic modelling can contribute to the improvement of decision making in a restructured power industry. We argue that the use of such modelling approaches has become more important after the introduction of competitive power markets, due to the participants' increased exposure to price fluctuations and economic risk. Our models can be applied by individual participants in the power system to evaluate investment projects for new power generation capacity. The models can also serve as a decision support tool on a regulatory level, providing analyses of the long-term performance of the power system under different regulations and market designs. In Chapter 1, we give a brief introduction to the ongoing development towards restructuring and liberalisation of the electrical power system. A discussion of the operation and organisation of restructured power systems is also provided. In Chapter 2, we look more specifically at different modelling approaches for expansion planning in electrical power systems. We also discuss how the contributions in this thesis compare to previous work in the field of decision support models for long-term planning in both regulated and competitive power systems. In Chapter 3, we develop a power market simulation model based on system dynamics. The advantages and limitations of using descriptive system dynamics models for long-term planning purposes in this context are also discussed. Chapter 4 is devoted to a novel optimisation

  11. Long-term availability of global uranium resources

    Monnet, Antoine

    2016-01-01

    From a global perspective, a low-carbon path to development driven by a growth of nuclear power production raises issues about the availability of uranium resources. Future technologies allowing nuclear reactors to overcome the need for natural uranium will take time to fully deploy. To address these issues, we analyze the conditions of availability of uranium in the 21. century. The first two conditions are technical accessibility and economic interest, both related to the cost of production. We study them using a model that estimates the ultimate uranium resources (amounts of both discovered and undiscovered resources) and their costs. This model splits the world into regions and the resource estimate for each region derives from the present knowledge of the deposits and economic filtering. The output is a long-term supply curve that illustrates the quantities of uranium that are technically accessible as a function of their cost of production. We identify the main uncertainties of these estimates and we show that with no regional breakdown, the ultimate resources are underestimated. The other conditions of availability of uranium covered in our study are related to the market dynamics, i.e. they derive from the supply and demand clearing mechanism. To assess their influence, they are introduced as dynamic constraints in a partial equilibrium model. This model of the uranium market is deterministic, and market players are represented by regions. For instance, it takes into account the short-term correlation between price and exploration expenditures, which is the subject of a dedicate econometric study. In the longer term, constraints include anticipation of demand by consumers and a gradual depletion of the cheapest ultimate resources. Through a series of prospective simulations, we demonstrate the strong influence on long-term price trends of both the growth rate of demand during the 21. century and its anticipation. Conversely, the uncertainties related to the

  12. Long-term variability of dust-storms in Iceland

    Dagsson-Waldhauserová, Pavla; Ólafsson, Haraldur; Arnalds, Ólafur

    2013-04-01

    Iceland is a volcanic island in the North Atlantic Ocean with maritime climate. In spite of moist climate, large areas are with limited vegetation cover where >40% of Iceland is classified with considerable to very severe erosion and 21% of Iceland are volcanic sandy deserts. Natural emissions from these sources influenced by strong winds affect not only regional air quality in Iceland ("Reykjavik haze") but dust particles are transported over the Atlantic ocean and Arctic Ocean > 1000 km at times. The study places Icelandic dust production area into international perspective, present long term frequency of dust storm events in NE Iceland, and estimate dust aerosol concentrations during reported dust events. Meteorological observations with dust presence codes and related visibility were used to identify the frequency and the long-term changes in dust production in NE Iceland. There were annually 16.4 days on average with reported dust observations on weather stations within the NE erosion area, indicating extreme dust plume activity and erosion within the NE deserts, even though the area is covered with snow during the major part of winter. During the 2000s the highest occurrence of dust events in six decades was reported. We have measured saltation and aeolian transport during dust/volcanic ash storms in Iceland which give some of the most intense wind erosion events ever measured. Icelandic dust affects the ecosystems over much of Iceland and causes regional haze. It is likely to affect the ecosystems of the oceans around Iceland, and it brings dust that lowers the albedo of the Icelandic glaciers, increasing melt-off due to global warming. The study indicates that Icelandic dust is not only a substantial source for regional air pollution, but may be considered to contribute to the Arctic haze phenomena and Arctic air pollution.

  13. Hot functional test chemistry - long term experience

    Vonkova, K.; Kysela, J.; Marcinsky, M.; Martykan, M.

    2010-01-01

    Primary circuit materials undergo general corrosion in high temperature, deoxygenated, neutral or mildly alkaline solutions to form thin oxide films. These oxide layers (films) serve as protective film and mitigate the further corrosion of primary materials. Inner chromium-rich oxide layer has low cation diffusion coefficients and thus control iron and nickel transport from the metal surface to the outer layer and their dissolution into the coolant. Much less corrosion products are generated by the compact, integral and stable oxide (passivation) layer. For the latest Czech and Slovak stations commissioned (Temelin and Mochovce) a modified Hot Functional Test (HFT) chemistry was developed in the NRI Rez. Chromium rich surface layer formatted due to modified HTF chemistry ensures lower corrosion rates and radiation field formation and thus also mitigates crud formation during operation. This procedure was also designed to prepare the commissioned unit for the further proper water chemistry practise. Mochovce 1 (SK) was the first station commissioned using these recommendations in 1998. Mochovce 2 (1999) and Temelin 1 and 2 (CZ - 2000 and 2002) were subsequently commissioned using these guidelines too. The main principles of the controlled primary water chemistry applied during the hot functional tests are reviewed and importance of the water chemistry, technological and other relevant parameters is stressed regarding to the quality of the passive layer formed on the primary system surfaces. Samples from Mochovce indicated that duplex oxide layers up to 20 μm thick were produced, which were mainly magnetite substituted with nickel and chromium (e.g. 60-65% Fe, 18-28% Cr, 9-12% Ni, <1% Mn and 1-2% Si on a stainless steel primary circuit sample). Long term operation experience from both nuclear power plants are discussed in this paper. Radiation field, occupational radiation exposure and corrosion layers evolution during the first c. ten years of operation are

  16. Nuclear power from a long term global perspective

    Davis, D.A.

    1994-01-01

    The global problem with energy, now and into the longer term, is the same as the global problem with food. There is no absolute shortage of either and nor is there likely to be. But the pattern of availability is such that large numbers of people have inadequate supplies of one or the other, or of both. Thus, in considering global energy futures the problems are more about energy distribution than about its absolute availability: it is important that in arguing its case for expansion the nuclear industry bears that fact in mind.

  17. Advanced design cultures long-term perspective and continuous innovation

    2015-01-01

    This book describes new thinking and practice in Advanced Design (ADD) – design that is not merely highly developed but anticipates the future by envisioning novel products and processes. The focus is especially on the front end of innovation and the search for solutions in complex pioneering processes using design-related tools and practices. The book opens by describing these tools, the approaches that characterize ADD, and its historical dimension. Specific fields in which ADD has flourished are then examined, exploring the dynamics between research and design. The coverage ranges from transportation, lighting, and electrical appliances through to business networks, technology parks, and the development of ground-breaking materials. AdvanceDesign is the name of the research group at the Politecnico di Milano (Italy’s largest technical university) of which the authors are members. It was chosen to reflect both the “advanced”, tangible dimension of design in terms of modern product development, mater...

  18. Oncology nurses′ recognition of long-term cancer survivorship care in Japan

    Asako Miura

    2015-01-01

    Full Text Available Objective: This study aims to assess the knowledge of definition of cancer survivors among Japanese oncology nurses and their roles in long-term cancer survivorship care. Methods: A structured self-administered and self-report questionnaire created by the study investigators was given to members of the Japanese Society of Cancer Nursing. The subjects were 81 female oncology nurses. Results: Forty-nine nurses had 11 or more years of nursing experience, while 27 nurses had cancer-related nursing certifications such as, certification in oncology nursing specialist. This study population had rather rich experience in oncology nursing. Sixty-two nurses defined a cancer survivor from the time of diagnosis, while the nurses′ recognition of long-term survivorship care was poor, compared with nursing care at the time of diagnosis, during treatment, and end of life. Conclusions: The nurses were aware of the needs to recognize and address issues faced by long-term cancer survivors and for nursing study, but very few put the effective patient education and interventions into practice. It is because oncology nurses have few chances to see cancer survivors who go out of the hands of healthcare professionals. In increasing the number of long-term survivors, long-term survivorship care is needed in addition to incorporating such education into undergraduate and graduate programs. Further study on the knowledge of long-term cancer survivorship care and nursing practices are required.

  1. African-American Female Students and STEM: Principals' Leadership Perspectives

    Sampson, Kristin Morgan

    As the U.S. becomes more diverse, school leaders, major corporations, and areas of national defense continue to investigate science, technology, engineering and math (STEM) education issues. African-American female students have historically been underrepresented in STEM fields, yet educational leadership research, examining this population is limited. The purpose of this qualitative study was to explore how principals support African-American female students in schools with a STEM program. The Critical Race Theory (CRT)was used as a theoretical framework to highlight the inadequacies to support educational inequalities. The application of the CRT in this study is due to the embedded inequality practices within the educational system, that have resulted in the underrepresentation of African-American female students in STEM. To complement CRT, the transformative leadership model was also utilized to examine the emancipatory leadership practices principals utilized. These theories framed the context of this study by recognizing the need to address how support is actualized to African-American female students in STEM by their principals. A case study approach was an appropriate method to answer the two research questions, 1) How do principals feel they support African-American female students in their STEM programs? and 2) What practices do principals engage in that support underrepresented students in STEM? This approach intended to uncover how a principal leads a multifaceted population of underrepresented students in STEM programs. Two principals of STEM schools, where more than 50% of the population were African-American, were interviewed and observed completing daily operations at community-wide events. The STEM Coordinators and a teacher were also interviewed, and test scores were examined to provide further information about the STEM program, and public records were obtained to analyze the principals' means of communication. I found that principals supported

    Background. We report long-term outcomes in adult patients with craniopharyngioma following surgery and radiation therapy (RT). Material and methods. Fifty-three patients treated with RT (median, 50 Gy in 25 fractions) between 1980 and 2009 with pathologically confirmed craniopharyngioma were reviewed (53% solid and 47% cystic/solid). The median age was 53 years (range, 22-76), 53% were female, 83% were sub-totally resected, 6% were gross totally resected and 11% had a biopsy and/or cyst aspiration alone. RT was delivered adjuvantly in 53% of patients as opposed to salvage intent upon progression. Results. Median follow-up was seven years (86 months, range, 8-259). The 5- and 10-year progression-free survival (PFS) rates were 85% and 69%, overall survival (OS) rates were 76% and 70%, and cause-specific survival (CSS) rates were both 88%, respectively. Both univariable and multivariable analysis identified age (<53 or {>=}53) as a prognostic factor for OS (p =0.0003) and CSS (p =0.05). PFS was observed to be worse in patients with >2 surgeries prior to RT (p =0.01). Neither the intent of radiation or tumor type (cystic vs. solid/cystic) were prognostic or predictive. New endocrinopathies and visual dysfunction were observed in 53% and 17% of patients post-surgery, and in 11% and 6% post-RT, respectively. Conclusion. We report long-term favorable PFS, CSS and OS for craniopharyngioma post-RT. We observe age as a significant prognostic factor, however, timing of radiation was not.

    2002-01-01

    Within the framework of nuclear waste management studies, the 'ose-composent' concept is considered to be an attractive option for the long-term perspective. This paper proposes a new system called TASSE ('Thorium-based Accelerator-drives System with Simplified fuel cycle for long-term Energy production') destined for the current French park renewal. The main idea of the TASSE concept is to simplify both the front end and the back end of the fuel cycle. Its major goal is to provide electricity with low waste production and economical competitiveness. (author)

    2015-09-01

    To evaluate the long-term effects of the standard (Class II) Balters bionator in growing patients with Class II malocclusion with mandibular retrusion by using morphometrics (thin-plate spline [TPS] analysis). Twenty-three Class II patients (8 male, 15 female) were treated consecutively with the Balters bionator (bionator group). The sample was evaluated at T0, start of treatment; T1, end of bionator therapy; and T2, long-term observation (including fixed appliances). Mean age at the start of treatment was 10 years 2 months (T0); at posttreatment, 12 years 3 months (T1); and at long-term follow-up, 18 years 2 months (T2). The control group consisted of 22 subjects (11 male, 11 female) with untreated Class II malocclusion. Lateral cephalograms were analyzed at the three time points for all groups. TPS analysis evaluated statistical differences (permutation tests) in the craniofacial shape and size between the bionator and control groups. TPS analysis showed that treatment with the bionator is able to produce favorable mandibular shape changes (forward and downward displacement) that contribute significantly to the correction of the Class II dentoskeletal imbalance. These results are maintained at a long-term observation after completion of growth. The control group showed no statistically significant differences in the correction of Class II malocclusion. This study suggests that bionator treatment of Class II malocclusion produces favorable results over the long term with a combination of skeletal and dentoalveolar shape changes.

  5. Safety analysis SFR 1. Long-term safety

    2008-12-15

    An updated assessment of the long-term safety of SKB's final repository for radioactive operational waste, SFR 1, is presented in this report. The report is included in the safety analysis report for SFR 1. The most recent account of long-term safety was submitted to the regulatory authorities in 2001. The present report has been compiled on SKB's initiative to address the regulatory authorities' viewpoints regarding the preceding account of long-term safety. Besides the new mode of working with safety functions there is another important difference between the 2001 safety assessment and the current assessment: The time horizon in the current assessment has been extended to 100,000 years in order to include the effect of future climate changes. The purpose of this renewed assessment of the long-term safety of SFR 1 is to show with improved data that the repository is capable of protecting human health and the environment against ionizing radiation in a long-term perspective. This is done by showing that calculated risks lie below the risk criteria stipulated by the regulatory authorities. SFR 1 is built to receive, and after closure serve as a passive repository for, low. and intermediate-level radioactive waste. The disposal chambers are situated in rock beneath the sea floor, covered by about 60 metres of rock. The underground part of the facility is reached via two tunnels whose entrances are near the harbour. The repository has been designed so that it can be abandoned after closure without further measures needing to be taken to maintain its function. The waste in SFR 1 is short-lived low- and intermediate-level waste. After 100 years the activity is less than half, and after 1,000 years only about 2% of the original activity remains. The report on long-term safety comprises eleven chapters. Chapter 1 Introduction.

  11. Long-Term Patency of Lymphovenous Anastomoses: A Systematic Review.

    Tourani, Saam S; Taylor, G Ian; Ashton, Mark W

    2016-08-01

    With advancements in technology and microsurgical techniques, lymphovenous anastomosis has become a popular reconstructive procedure in the treatment of chronic lymphedema. However, the long-term patency of these anastomoses is not clear in the literature. A systematic review of the MEDLINE and EMBASE databases was performed to assess the reported long-term patency of lymphovenous anastomoses. A total of eight studies satisfied the inclusion criteria. Pooled data from four similar experiments in normal dogs showed an average long-term (≥5 months) patency of 52 percent. The only experiment in dogs with chronic lymphedema failed to show any long-term patency. The creation of peripheral lymphovenous anastomoses with a moderate long-term patency rate has become technically possible. However, the long-term results in chronic lymphedema are limited.

  12. Reforming Long-Term Care Funding in Alberta.

    Crump, R Trafford; Repin, Nadya; Sutherland, Jason M

    2015-01-01

    Like many provinces across Canada, Alberta is facing growing demand for long-term care. Issues with the mixed funding model used to pay long-term care providers had Alberta Health Services concerned that it was not efficiently meeting the demand for long-term care. Consequently, in 2010, Alberta Health Services introduced the patient/care-based funding (PCBF) model. PCBF is similar to activity-based funding in that it directly ties the complexity and care needs of long-term care residents to the payment received by long-term care providers. This review describes PCBF and discusses some of its strengths and weaknesses. In doing so, this review is intended to inform other provinces faced with similar long-term care challenges and contemplating their own funding reforms.

  13. The Role of Online Communication in Long-Term Cyberbullying Involvement Among Girls and Boys.

    Festl, Ruth; Quandt, Thorsten

    2016-09-01

    Digital media, especially mobile communication technologies, enable adolescents to explore and experiment with each other with only limited adult control. Conflicts between peers can be easily staged since nearly everybody can be reached at any time under the radar of authorities. Therefore, involvement in conflicts and bullying might depend on how adolescents use and behave online. In the present study, we provide a comprehensive picture of the role aspects of online communication play in long-term involvement in cyberbullying. We focused on a gender-specific perspective, as girls and boys were found to differ not only according to their online communication but also in their cyberbullying involvement. Using a two-wave panel survey of 1817 adolescents between 13 and 17 years (56 % female), we found that girls' cyberbullying involvement (perpetration and victimization) could be traced back to more intensive online social activities and a higher amount of online contact with strangers. In contrast, for boys, only higher exposure to antisocial media content predicted higher levels of victimization over time. The findings indicate that certain patterns of online communication increase the cyberbullying risk over time. However, it needs to be noted that these risk factors vary between girls and boys.

    Mery, Frederic; Kawecki, Tadeusz J.

    2005-01-01

    Two distinct forms of consolidated associative memory are known in Drosophila: long-term memory and so-called anesthesia-resistant memory. Long-term memory is more stable, but unlike anesthesia-resistant memory, its formation requires protein synthesis. We show that flies induced to form long-term memory become more susceptible to extreme stress (such as desiccation). In contrast, induction of anesthesia-resistant memory had no detectable effect on desiccation resistance. This finding may hel...

  15. Private long-term care insurance and state tax incentives.

    Stevenson, David G; Frank, Richard G; Tau, Jocelyn

    2009-01-01

    To increase the role of private insurance in financing long-term care, tax incentives for long-term care insurance have been implemented at both the federal and state levels. To date, there has been surprisingly little study of these initiatives. Using a panel of national data, we find that market take-up for long-term care insurance increased over the last decade, but state tax incentives were responsible for only a small portion of this growth. Ultimately, the modest ability of state tax incentives to lower premiums implies that they should be viewed as a small piece of the long-term care financing puzzle.

    Negin, C.A.; Simpson, J.M.; Hostetler, D.R.

    1992-09-01

    The creation of a Life Cycle Management (LCM) group at utilities to evaluate the long term capital refurbishment needs is gaining favor. Among the functions of such groups can be the responsibility for recommending long term capital planning projects based on results of evaluations of systems, structures, and components that are not only essential to achieving the full current license term of operation, but also to extend the service life of the plant. Making such recommendations, in content and timing, requires the ability to view all recommendations in the context of an overall capital budget and long range outage impacts. This report illustrates an approach for creating a Long-Term Capital Plan with methods for deciding on, compiling, integrating, and presenting projects from the perspective of an LCM program for a nuclear power plant. It also addresses a rationale for capitalization of LCM program activities that would not be allowed under current accounting treatment

    Stilling, Nicolaj M; Fristrup, Claus; Wettergren, André

    2015-01-01

    BACKGROUND: The aim of this retrospective study was to evaluate the peri-operative and long-term outcome after early repair with a hepaticojejunostomy (HJ). METHODS: Between 1995 and 2010, a nationwide, retrospective multi-centre study was conducted. All iatrogenic bile duct injury (BDI) sustained...... during a cholecystectomy and repaired with HJ in the five Hepato-Pancreatico-Biliary centres in Denmark were included. RESULTS: In total, 139 patients had an HJ repair. The median time from the BDI to reconstruction was 5 days. A concomitant vascular injury was identified in 26 cases (19%). Post...... with BDI repaired by early HJ we found a considerable risk of long-term complications (e.g. 30% stricture rate) and mortality in both the short- and the long-term perspective....

    2018-03-01

    To explore barriers to ethical nursing practice for older adults in long-term care facilities from the perspectives of nurses in South Korea. The number of older adults admitted to long-term care facilities is increasing rapidly in South Korea. To provide this population with quality care, a solid moral foundation should be emphasised to ensure the provision of ethical nursing practices. Barriers to implementing an ethical nursing practice for older adults in long-term care facilities have not been fully explored in previous literature. A qualitative, descriptive design was used to explore barriers to ethical nursing practice as perceived by registered nurses in long-term care facilities in South Korea. Individual interviews were conducted with 17 registered nurses recruited using purposive (snowball) sampling who care for older adults in long-term care facilities in South Korea. Data were analysed using qualitative content analysis. Five main themes emerged from the data analysis concerning barriers to the ethical nursing practice of long-term care facilities: emotional distress, treatments restricting freedom of physical activities, difficulty coping with emergencies, difficulty communicating with the older adult patients and friction between nurses and nursing assistants. This study has identified methods that could be used to improve ethical nursing practices for older adults in long-term care facilities. Because it is difficult to improve the quality of care through education and staffing alone, other factors may also require attention. Support programmes and educational opportunities are needed for nurses who experience emotional distress and lack of competency to strengthen their resilience towards some of the negative aspects of care and being a nurse that were identified in this study. © 2017 John Wiley & Sons Ltd.

  1. Family ties after divorce: long-term implications for children.

    Ahrons, Constance R

    2007-03-01

    Drawing on the data from the longitudinal Binuclear Family Study, 173 grown children were interviewed 20 years after their parents' divorce. This article addresses two basic questions: (1) What impact does the relationship between parents have on their children 20 years after the divorce? and (2) When a parent remarries or cohabits, how does it impact a child's sense of family? The findings show that the parental subsystem continues to impact the binuclear family 20 years after marital disruption by exerting a strong influence on the quality of relationships within the family system. Children who reported that their parents were cooperative also reported better relationships with their parents, grandparents, stepparents, and siblings. Over the course of 20 years, most of the children experienced the remarriage of one or both parents, and one third of this sample remembered the remarriage as more stressful than the divorce. Of those who experienced the remarriage of both of their parents, two thirds reported that their father's remarriage was more stressful than their mother's. When children's relationships with their fathers deteriorated after divorce, their relationships with their paternal grandparents, stepmother, and stepsiblings were distant, negative, or nonexistent. Whether family relationships remain stable, improve, or get worse is dependent on a complex interweaving of many factors. Considering the long-term implications of divorce, the need to emphasize life course and family system perspectives is underscored.

  2. Long-term monitoring of blazars - the DWARF network

    Backes, Michael; Biland, Adrian; Boller, Andrea; Braun, Isabel; Bretz, Thomas; Commichau, Sebastian; Commichau, Volker; Dorner, Daniela; von Gunten, Hanspeter; Gendotti, Adamo; Grimm, Oliver; Hildebrand, Dorothée; Horisberger, Urs; Krähenbühl, Thomas; Kranich, Daniel; Lustermann, Werner; Mannheim, Karl; Neise, Dominik; Pauss, Felicitas; Renker, Dieter; Rhode, Wolfgang; Rissi, Michael; Rollke, Sebastian; Röser, Ulf; Stark, Luisa Sabrina; Stucki, Jean-Pierre; Viertel, Gert; Vogler, Patrick; Weitzel, Quirin

    The variability of the very high energy (VHE) emission from blazars seems to be connected with the feeding and propagation of relativistic jets and with their origin in supermassive black hole binaries. The key to understanding their properties is measuring well-sampled gamma-ray lightcurves, revealing the typical source behavior unbiased by prior knowledge from other wavebands. Using ground-based gamma-ray observatories with exposures limited by dark-time, a global network of several telescopes is needed to carry out fulltime measurements. Obviously, such observations are time-consuming and, therefore, cannot be carried out with the present state of the art instruments. The DWARF telescope on the Canary Island of La Palma is dedicated to monitoring observations. It is currently being set up, employing a costefficient and robotic design. Part of this project is the future construction of a distributed network of small telescopes. The physical motivation of VHE long-term monitoring will be outlined in detail and the perspective for a network for 24/7 observations will be presented.

  3. Nursing Work in Long-Term Care: An Integrative Review.

    Montayre, Jed; Montayre, Jasmine

    2017-11-01

    Evidence suggests that delivery of good nursing care in long-term care (LTC) facilities is reflected in nurses' descriptions of the factors and structures that affect their work. Understanding the contemporary nature of nursing work in aged care will influence policies for improving current work structures in this practice setting. The current review aims to present a contemporary perspective of RNs' work in LTC facilities. A comprehensive search and purposeful selection of the literature was conducted using CINAHL, PubMed, Medline, Scopus, and Google Scholar databases. Nine studies were eligible for review. Common themes revealed that nursing work in aged care settings is characterized by RNs providing indirect care tasks-primarily care coordination, engaging in non-nursing activities, and having an expanded and overlapping role. As care providers, aged care RNs do not always provide direct care as part of their nursing work. The scope of RN work beyond its clinical nature or performance of non-nursing tasks adds complexity in clarifying RN work roles in aged care. [Journal of Gerontological Nursing, 43(11), 41-49.].

  4. Modulation of working memory updating: Does long-term memory lexical association matter?

    Artuso, Caterina; Palladino, Paola

    2016-02-01

    The aim of the present study was to investigate how working memory updating for verbal material is modulated by enduring properties of long-term memory. Two coexisting perspectives that account for the relation between long-term representation and short-term performance were addressed. First, evidence suggests that performance is more closely linked to lexical properties, that is, co-occurrences within the language. Conversely, other evidence suggests that performance is linked more to long-term representations which do not entail lexical/linguistic representations. Our aim was to investigate how these two kinds of long-term memory associations (i.e., lexical or nonlexical) modulate ongoing working memory activity. Therefore, we manipulated (between participants) the strength of the association in letters based on either frequency of co-occurrences (lexical) or contiguity along the sequence of the alphabet (nonlexical). Results showed a cost in working memory updating for strongly lexically associated stimuli only. Our findings advance knowledge of how lexical long-term memory associations between consonants affect working memory updating and, in turn, contribute to the study of factors which impact the updating process across memory systems.

  5. Long-Term Engagement in Formal Volunteering and Well-Being: An Exploratory Indian Study.

    Elias, Jereesh K; Sudhir, Paulomi; Mehrotra, Seema

    2016-09-27

    Sustained engagement in volunteering and its correlates have been examined in many studies across the globe. However, there is a dearth of research that explores the perspectives of long-term formal volunteers on the nature of changes perceived in oneself as a result of volunteering. Moreover, the linkages between psychological well-being and volunteering have been insufficiently explored. The present study was aimed at addressing these gaps. A heterogeneous sample of 20 long-term formal volunteer engaged in volunteering across different voluntary organisations in a southern metropolitan Indian city formed the primary sample for the study. In addition, a group of 21 short-term volunteers, matched on age, income and gender, was utilised for comparison with long-term volunteers on well-being indices. A semi structured interview schedule was used to explore self-perceived changes attributable to volunteering experience. In addition, a few standardised measures were used to comprehensively assess subjective well-being and psychological well-being. The interview data provided rich descriptions of perceived positive changes in self across cognitive, behavioral and emotional domains. Mirroring these patterns, the quantitative analyses indicated that long-term volunteers experienced higher levels of psychological well-being (sense of mastery and competence, self-acceptance and sense of engagement and growth) than short-term volunteers. The potential mechanisms involved in beneficial outcomes of long-term volunteering and implications for further research are highlighted.

  6. Dystrophic Cutaneous Calcification and Metaplastic Bone Formation due to Long Term Bisphosphonate Use in Breast Cancer

    Ali Murat Tatlı

    2013-01-01

    Full Text Available Bisphosphonates are widely used in the treatment of breast cancer with bone metastases. We report a case of a female with breast cancer presented with a rash around a previous mastectomy site and a discharge lesion on her right chest wall in August 2010. Biopsy of the lesion showed dystrophic calcification and metaplastic bone formation. The patient’s history revealed a long term use of zoledronic acid for the treatment of breast cancer with bone metastasis. We stopped the treatment since we believed that the cutaneous dystrophic calcification could be associated with her long term bisphosphonate therapy. Adverse cutaneous events with bisphosphonates are very rare, and dystrophic calcification has not been reported previously. The dystrophic calcification and metaplastic bone formation in this patient are thought to be due to long term bisphosphonate usage.

  1. Long-Term Dynamics of Autonomous Fractional Differential Equations

    Liu, Tao; Xu, Wei; Xu, Yong; Han, Qun

    This paper aims to investigate long-term dynamic behaviors of autonomous fractional differential equations with effective numerical method. The long-term dynamic behaviors predict where systems are heading after long-term evolution. We make some modification and transplant cell mapping methods to autonomous fractional differential equations. The mapping time duration of cell mapping is enlarged to deal with the long memory effect. Three illustrative examples, i.e. fractional Lotka-Volterra equation, fractional van der Pol oscillator and fractional Duffing equation, are studied with our revised generalized cell mapping method. We obtain long-term dynamics, such as attractors, basins of attraction, and saddles. Compared with some existing stability and numerical results, the validity of our method is verified. Furthermore, we find that the fractional order has its effect on the long-term dynamics of autonomous fractional differential equations.

  2. Experimental Researches on Long-Term Strength of Granite Gneiss

    Lin Liu

    2015-01-01

    Full Text Available It is important to confirm the long-term strength of rock materials for the purpose of evaluating the long-term stability of rock engineering. In this study, a series of triaxial creep tests were conducted on granite gneiss under different pore pressures. Based on the test data, we proposed two new quantitative methods, tangent method and intersection method, to confirm the long-term strength of rock. Meanwhile, the isochronous stress-strain curve method was adopted to make sure of the accuracy and operability of the two new methods. It is concluded that the new methods are suitable for the study of the long-term strength of rock. The effect of pore pressure on the long-term strength of rock in triaxial creep tests is also discussed.

  3. Long-Term Memory Performance in Adult ADHD.

    Skodzik, Timo; Holling, Heinz; Pedersen, Anya

    2017-02-01

    Memory problems are a frequently reported symptom in adult ADHD, and it is well-documented that adults with ADHD perform poorly on long-term memory tests. However, the cause of this effect is still controversial. The present meta-analysis examined underlying mechanisms that may lead to long-term memory impairments in adult ADHD. We performed separate meta-analyses of measures of memory acquisition and long-term memory using both verbal and visual memory tests. In addition, the influence of potential moderator variables was examined. Adults with ADHD performed significantly worse than controls on verbal but not on visual long-term memory and memory acquisition subtests. The long-term memory deficit was strongly statistically related to the memory acquisition deficit. In contrast, no retrieval problems were observable. Our results suggest that memory deficits in adult ADHD reflect a learning deficit induced at the stage of encoding. Implications for clinical and research settings are presented.

  4. Current perspectives on the etiology and manifestation of the "silent" component of the Female Athlete Triad

    Mallinson RJ

    2014-05-01

    Full Text Available Rebecca J Mallinson, Mary Jane De SouzaDepartment of Kinesiology, Women's Health and Exercise Laboratory in Noll Laboratory, Pennsylvania State University, University Park, PA, USAAbstract: The Female Athlete Triad (Triad represents a syndrome of three interrelated conditions that originate from chronically inadequate energy intake to compensate for energy expenditure; this environment results in insufficient stored energy to maintain physiological processes, a condition known as low energy availability. The physiological adaptations associated with low energy availability, in turn, contribute to menstrual cycle disturbances. The downstream effects of both low energy availability and suppressed estrogen concentrations synergistically impair bone health, leading to low bone mineral density, compromised bone structure and microarchitecture, and ultimately, a decrease in bone strength. Unlike the other components of the Triad, poor bone health often does not have overt symptoms, and therefore develops silently, unbeknownst to the athlete. Compromised bone health among female athletes increases the risk of fracture throughout the lifespan, highlighting the long-term health consequences of the Triad. The purpose of this review is to examine the current state of Triad research related to the third component of the Triad, ie, poor bone health, in an effort to summarize what we know, what we are learning, and what remains unknown.Keywords: female athlete Triad, bone health, treatment

  5. Long-term neuromuscular training and ankle joint position sense.

    Kynsburg, A; Pánics, G; Halasi, T

    2010-06-01

    Preventive effect of proprioceptive training is proven by decreasing injury incidence, but its proprioceptive mechanism is not. Major hypothesis: the training has a positive long-term effect on ankle joint position sense in athletes of a high-risk sport (handball). Ten elite-level female handball-players represented the intervention group (training-group), 10 healthy athletes of other sports formed the control-group. Proprioceptive training was incorporated into the regular training regimen of the training-group. Ankle joint position sense function was measured with the "slope-box" test, first described by Robbins et al. Testing was performed one day before the intervention and 20 months later. Mean absolute estimate errors were processed for statistical analysis. Proprioceptive sensory function improved regarding all four directions with a high significance (pneuromuscular training has improved ankle joint position sense function in the investigated athletes. This joint position sense improvement can be one of the explanations for injury rate reduction effect of neuromuscular training.

    2011-01-01

    Little is known about the long-term effectiveness of albendazole in the medical therapy of non-complicated hepatic cystic echinococcosis (HCE) in resource-constrained settings. We performed a retrospective review of patients starting albendazole for HCE in Lima, Peru from January 1997 to December 2007. Patients successfully recontacted underwent chart abstraction and clinical and ultrasonographic reevaluation. Descriptive statistics were used to delineate patient characteristics and treatment effectiveness at the conclusion of albendazole and after reevaluation. Patients (N = 27) were primarily female, mean age was 51. Initial treatment success at albendazole conclusion was 26% (N = 7) per patient and 37.5% (N = 24) per cyst. After 3.8 ± 2.5 years, albendazole success was 34% (N = 9) per patient and 40% (N = 24) per cyst. We found a gap in the effectiveness of albendazole HCE therapy compared with the efficacy reported in clinical trials. This underscores the need for further investigation into alternate therapeutic strategies for this neglected disease. PMID:22144447

    Movsas, Benjamin; Movsas, Tammy Z.; Steinberg, Seth M.; Okunieff, Paul

    1995-01-01

    Purpose: To analyze possible long-term effects of pituitary irradiation on visual fields and acuity. Methods and Materials: Eighty-six patients were treated with radiotherapy for pituitary tumors at the National Cancer Institute between 1980 and 1991. Twenty-one patients had baseline preradiation and long-term follow-up visual fields. Eyes were followed with serial Goldmann or Humphrey visual field testing. Neuroradiologic correlation was made with the available brain scans. There were 12 females and 9 males with an median age of 44. Eighteen patients had hormone-secreting tumors and three had chromophobe adenomas. All but one patient with an inoperable invasive macroadenoma were irradiated after one or more transphenoidal resections or a craniotomy. The indications for radiation in the operable patients were: nine patients, partial tumor resection; nine patients, tumor recurrence; and two patients, persistent hormonal elevation after surgery. The median dose delivered was 50 Gy (45-59.4 Gy). The average field size was 6 x 6 cm (5 x 5 cm to 10 x 12.5 cm). Results: With a median follow-up of 48 months (14-128) after radiotherapy, 1 out of 21 patients has recurred (at 8 months) and all patients are alive. Of the 38 sighted eyes, 27 had normal visual fields before and after radiation, 7 eyes showed improvement, and 4 eyes had a stable defect, mostly in the superior temporal region. There were no cases of radiation-induced visual field or acuity deterioration. Six out of 21 patients (29%) had neurologic symptoms in follow-up, most of which appeared vascular in nature. Four patients complained of atypical migranous-like headaches that first began 1.5-3 years following treatment. One patient complained of recurrent vertical diplopia and one patient had a cerebral vascular accident 7 years following therapy. A dose-related association with these neurovascular symptoms approached statistical significance. Only 1 out of 11 (9%) patients who received doses less than or equal

  9. Analysis of the Italian generic medicines retail market: recommendations to enhance long-term sustainability.

    Dylst, Pieter; Vulto, Arnold; Simoens, Steven

    2015-02-01

    Italy is among the European countries with the lowest uptake of generic medicines. This paper provides a perspective on the Italian generic medicines retail market. Fast market entrance of generic medicines in Italy is hindered by several factors: the existence of Complementary Protection Certificates in the past, the large market for copies and multiple cases of patent linkage. Prices of generic medicines in Italy are low compared to other European countries. To contain pharmaceutical expenditure, pharmaceutical companies are currently forced to pay back in case of overspending, which disproportionally penalizes small and fast growing companies, to which most generic companies belong to. Current demand-side policies do not successfully stimulate the use of generic medicines. The current market environment surrounding the Italian generic medicines retail market (i.e., low prices, low volumes) threatens its long-term sustainability. Recommendations to enhance the long-term sustainability of the Italian generic medicines retail market round off this perspective paper.

    Intracranial germinomas are sensitive to both chemotherapy and radiotherapy. For this reason, long-term survival or cure rate is excellent. It is therefore important for such patients, especially for younger children, to keep a high quality of life (QOL) after the treatment. Recently, whole ventricle radiotherapy with chemotherapy has been the treatment of choice for these tumors. However, in our institute, we perform radiotherapy alone as a standard treatment, using prophylactic craniospinal irradiation (CSI) or whole brain irradiation (WBI) with local tumor booster. The purpose of this study is to assess the long-term outcome of pediatric patients with intracranial germinomas in our institute. Twenty-three young patients (17 males and 6 females) ranging from 5 to 15 years were treated between 1990 and 2009 at University of Niigata. Mean age at the time of diagnosis was 10.7 years. Tumor locations were as follows: pineal regions in 6, suprasellar in 6, basal ganglia in 4, ventricles in 1, bifocal regions (pineal and suprasellar) in 2, and dissemination in 4 patients. Twenty (88%) patients had received radiotherapy alone: 15 (66%) with CSI, and 5 (22%) with WBI. Median doses for the whole brain, spine, and primary site were 26.6 Gy (range, 23.8-35.0), 25.9 Gy (range, 23.8-30.6), 49.8 Gy (range, 44.7-52.8), respectively. Three (12%) received chemotherapy with or without radiotherapy. We analyzed the survival and long-term QOL including hormonal sequel after the above treatments. The median follow-up period was 126 months (26 to 235 months). None of the 20 patients with radiotherapy alone suffered tumor recurrence, while 2 of the 3 with chemotherapy developed recurrences. Eleven (48%), including 9 with supurasellar region required hormone replacement therapy. Two (9%) were short stature compared with normal (mean-2 standard deviation). One (4%) developed a possible radiation-induced menigioma. In 15 patients aged 19 years or older, 13 (87%) graduated from senior high

    Korinko M.D.

    2017-03-01

    Full Text Available The article determines the importance of long-term and short-term liabilities for the management of financial and material resources of an enterprise. It reviews the aim, objects and information generators for realization of audit of short-term and long-term obligations. The organizing and methodical providing of audit of long-term and short-term liabilities of an enterprise are generalized. The authors distinguish the stages of realization of audit of long-term and short-term liabilities, the aim of audit on each of the presented stages, and recommend methodical techniques. It is fixed that it is necessary to conduct the estimation of the systems of internal control and record-keeping of an enterprise by implementation of public accountant procedures for determination of volume and maintenance of selection realization. After estimating the indicated systems, a public accountant determines the methodology for realization of public accountant verification of long-term and short-term liabilities. The analytical procedures that public accountants are expedient to use for realization of audit of short-term and long-term obligations are determined. The authors suggest the classification of the educed defects on the results of the conducted public accountant verification of short-term and long-term obligations.

  12. Modeling long-term dynamics of electricity markets

    Olsina, Fernando; Garces, Francisco; Haubrich, H.-J.

    2006-01-01

    In the last decade, many countries have restructured their electricity industries by introducing competition in their power generation sectors. Although some restructuring has been regarded as successful, the short experience accumulated with liberalized power markets does not allow making any founded assertion about their long-term behavior. Long-term prices and long-term supply reliability are now center of interest. This concerns firms considering investments in generation capacity and regulatory authorities interested in assuring the long-term supply adequacy and the stability of power markets. In order to gain significant insight into the long-term behavior of liberalized power markets, in this paper, a simulation model based on system dynamics is proposed and the underlying mathematical formulations extensively discussed. Unlike classical market models based on the assumption that market outcomes replicate the results of a centrally made optimization, the approach presented here focuses on replicating the system structure of power markets and the logic of relationships among system components in order to derive its dynamical response. The simulations suggest that there might be serious problems to adjust early enough the generation capacity necessary to maintain stable reserve margins, and consequently, stable long-term price levels. Because of feedback loops embedded in the structure of power markets and the existence of some time lags, the long-term market development might exhibit a quite volatile behavior. By varying some exogenous inputs, a sensitivity analysis is carried out to assess the influence of these factors on the long-run market dynamics

    Variable generation (VG) can reduce market prices over time and also the energy that other suppliers can sell in the market. The suppliers that are needed to provide capacity and flexibility to meet the long-term reliability requirements may, therefore, earn less revenue. This chapter discusses the topics of resource adequacy and revenue sufficiency - that is, determining and acquiring the quantity of capacity that will be needed at some future date and ensuring that those suppliers that offer the capacity receive sufficient revenue to recover their costs. The focus is on the investment time horizon and the installation of sufficient generation capability. First, the chapter discusses resource adequacy, including newer methods of determining adequacy metrics. The chapter then focuses on revenue sufficiency and how suppliers have sufficient opportunity to recover their total costs. The chapter closes with a description of the mechanisms traditionally adopted by electricity markets to mitigate the issues of resource adequacy and revenue sufficiency and discusses the most recent market design changes to address these issues.

  14. Long-Term Stewardship Baseline Report and Transition Guidance

    Kristofferson, Keith

    2001-11-01

    Long-term stewardship consists of those actions necessary to maintain and demonstrate continued protection of human health and the environment after facility cleanup is complete. As the Department of Energy’s (DOE) lead laboratory for environmental management programs, the Idaho National Engineering and Environmental Laboratory (INEEL) administers DOE’s long-term stewardship science and technology efforts. The INEEL provides DOE with technical, and scientific expertise needed to oversee its long-term environmental management obligations complexwide. Long-term stewardship is administered and overseen by the Environmental Management Office of Science and Technology. The INEEL Long-Term Stewardship Program is currently developing the management structures and plans to complete INEEL-specific, long-term stewardship obligations. This guidance document (1) assists in ensuring that the program leads transition planning for the INEEL with respect to facility and site areas and (2) describes the classes and types of criteria and data required to initiate transition for areas and sites where the facility mission has ended and cleanup is complete. Additionally, this document summarizes current information on INEEL facilities, structures, and release sites likely to enter long-term stewardship at the completion of DOE’s cleanup mission. This document is not intended to function as a discrete checklist or local procedure to determine readiness to transition. It is an overarching document meant as guidance in implementing specific transition procedures. Several documents formed the foundation upon which this guidance was developed. Principal among these documents was the Long-Term Stewardship Draft Technical Baseline; A Report to Congress on Long-Term Stewardship, Volumes I and II; Infrastructure Long-Range Plan; Comprehensive Facility Land Use Plan; INEEL End-State Plan; and INEEL Institutional Plan.

  17. The long-term power purchase: Recovery of capacity costs

    Cross, P.S.

    1990-01-01

    As electric utilities increase their reliance on the long-term power purchase as an alternative to utility-owned generation, the appropriate rate treatment of the costs established in the purchase agreement assumes growing importance. In the November 9, 1989, issue, the authors examined the recent trend among state regulators to treat the long-term purchase in a manner similar to the addition by a utility of a new plant, including a full-scale prudence review. This installment will review recent rulings on the related issue of rate recovery of long-term capacity costs through the fuel cost adjustment clause

  18. Long-term care financing through Federal tax incentives.

    Moran, D W; Weingart, J M

    1988-12-01

    Congress and the Administration are currently exploring various methods of promoting access to long-term care. In this article, an inventory of recent legislative proposals for using the Federal tax code to expand access to long-term care services is provided. Proposals are arrayed along a functional typology that includes tax mechanisms to encourage accumulation of funds, promote purchase of long-term care insurance, or induce the diversion of funds accumulated for another purpose (such as individual retirement accounts). The proposals are evaluated against the public policy objective of encouraging risk pooling to minimize social cost.

  19. Evaluation of long term leaching of borosilicate glasses

    Lanza, F.; Parnisari, E.

    1978-01-01

    For the evaluation of long term hazard of glass, data on long term glass leaching are needed. Moreover for long term leaching a model of homogeneous dissolution seems reasonable and ask for confirmation. Tests were performed at 30 0 , 80 0 , 100 0 , using an apparatus of the Soxhlet type, to 3.600 hours. Results were obtained as a weight loss and analysed following a relation with time composed by a parabolic and a linear part. Analysis of the surface layer using energy dispersion X ray spectrometry were performed. A critical analysis of the results and of the apparatus is presented

    2011-06-01

    Full Text Available Abstract Background Previous studies have shown the short-term or intermediate-term practice of yoga to be useful for ameliorating several mental disorders and psychosomatic disorders. However, little is known about the long-term influences of yoga on the mental state or stress-related biochemical indices. If yoga training has a stress-reduction effect and also improves an individual's mental states for a long time, long-term yoga practitioners may have a better mental state and lower stress-related biochemical indices in comparison to non-experienced participants. This study simultaneously examined the differences in mental states and urinary stress-related biochemical indices between long-term yoga practitioners and non-experienced participants. Methods The participants were 38 healthy females with more than 2 years of experience with yoga (long-term yoga group and 37 age-matched healthy females who had not participated in yoga (control group. Their mental states were assessed using the Profile of Mood States (POMS questionnaire. The level of cortisol, 8-hydroxydeoxyguanosine (8-OHdG and biopyrrin in urine were used as stress-related biochemical indices. Results The average self-rated mental disturbance, tension-anxiety, anger-hostility, and fatigue scores of the long-term yoga group were lower than those of the control group. There was a trend toward a higher vigor score in the long-term yoga group than that in the control group. There were no significant differences in the scores for depression and confusion in the POMS between the two groups. The urine 8-OHdG concentration showed a trend toward to being lower in the long-term yoga group in comparison to the control group. There were no significant differences in the levels of urine biopyrrin or cortisol. Conclusions The present findings suggest that long-term yoga training can reduce the scores related to mental health indicators such as self-rated anxiety, anger, and fatigue.

  4. In search of the elusive long-term price

    Connor, M.J.; Combs, J.

    1989-01-01

    The Uranium Institute, WNFM, and past USCEA sessions described and compared existing price reporting systems. The McGraw-Hill conference led to a rather heated discussion as to the propriety of spot prices having the influence they do on amounts paid in long-term contracts. The Ux representative proposed a future's market as a way that producers could hedge against some of the uncertainty of volatile spot market. In discussing the search for the elusive long-term price, there are two interrelated issues. The first is obvious-the search for a starting or initializing price that is representative of recently-signed or pending long-term contracts. The second is less obvious, but perhaps more important-the search for a successful mechanism for determining later delivery values in long-term contracts. This paper addresses the question of pricing mechanisms first

  6. Advancing an ethical framework for long-term care.

    Carter, Mary Whelan

    2002-02-01

    This article represents an effort to formulate an ethical framework for long-term care with the explicit purpose of providing a catalyst to promote further discourse and expand consideration of what an ethic of long-term care might entail. Grounding the discussion, an introduction to traditional ethical philosophy is presented, focusing mainly on the fundamentals of deontological and teleological ethical theories. Attention then shifts to a review of the more frequently cited principles found in the long-term care ethics literature, followed by a critique of the current reliance upon principlism to resolve ethical dilemmas in long-term care. In response to this criticism, an agent-driven ethical framework stressing dignity and respect for personhood, drawn from the philosophy of Immanuel Kant, is advanced.

  9. Strategies to meet the need for long-term data.

    Chalmers, John; Woodward, Mark; Borghi, Claudio; Manolis, Athanasios; Mancia, Giuseppe

    2016-08-01

    Chronic diseases afflict patients for many years, often to the end of life, and there is increasing need for estimating lifelong risk and for evaluating the effects of treatment in the long term. Yet recommendations for lifelong treatment are most frequently based on findings from randomized clinical trials lasting only a few years. There is therefore a clear need for much longer term data, and here we present the advantages and disadvantages of many strategies, including the use of long-term posttrial follow-up, of long-term prospective cohort studies, registry databases, and of administrative databases. We also emphasize the need for long-term cost-effectiveness studies. One of the most promising strategies comes from linkage of data gathered through the ever-expanding pool of administrative databases worldwide with data from other sources, including randomized trials and the many forms of observational study.

  11. Long-term memory, sleep, and the spacing effect.

    Bell, Matthew C; Kawadri, Nader; Simone, Patricia M; Wiseheart, Melody

    2014-01-01

    Many studies have shown that memory is enhanced when study sessions are spaced apart rather than massed. This spacing effect has been shown to have a lasting benefit to long-term memory when the study phase session follows the encoding session by 24 hours. Using a spacing paradigm we examined the impact of sleep and spacing gaps on long-term declarative memory for Swahili-English word pairs by including four spacing delay gaps (massed, 12 hours same-day, 12 hours overnight, and 24 hours). Results showed that a 12-hour spacing gap that includes sleep promotes long-term memory retention similar to the 24-hour gap. The findings support the importance of sleep to the long-term benefit of the spacing effect.

  18. Bentall operation in 375 patients: long-term results and predictors of death.

    Varrica, Alessandro; Satriano, Angela; de Vincentiis, Carlo; Biondi, Andrea; Trimarchi, Santi; Ranucci, Marco; Menicanti, Lorenzo; Frigiola, Alessandro

    2014-01-01

    The Bentall operation is a 40-year-old standardized procedure for treating aortic valve diseases and aneurysms involving the aortic root. The study aim was to analyze the results and predictors of long-term outcome after the Bentall procedure for aortic root diseases. Between January 1990 and December 2007, a total of 375 patients (296 males, 79 females) underwent the Bentall operation at the authors' institution. Bicuspid aortic valve (BAV) was present in 91 patients, and Marfan syndrome in 13. Thirty-six patients were treated as emergencies, and 30 for acute dissection. A concomitant surgical procedure was performed in 78 patients. The operative procedure included both classic Bentall and button techniques. Follow up data were obtained from hospital and office records and from telephone contacts. Kaplan-Meier survival analysis and Cox regression analysis were performed to investigate the predictors of long-term outcome. The overall in-hospital mortality was 4.5%, and after elective operations was 2.3%. A 20-year long-term follow up included 32 late deaths, of which 14 were cardiac-related. Freedom from late all-cause mortality at 5, 10, and 15 years was 97.1%, 81.9%, and 53.9%, respectively. At univariate analysis, long-term mortality was associated with age, diabetes, BAV, NYHA class III/IV, emergency treatment, cardiopulmonary bypass time, and coronary artery bypass grafting. Independent predictors of long-term mortality were age (OR 1.16; CI: 1.08-1.23), emergency surgery (OR 28; CI: 4-192) and BAV (OR 3; CI: 1.3-6.9). The Bentall procedure is a safe and durable operation, with a very good early and long-term results and a low rate of reoperation. In the present series, age, BAV and emergency surgery were important independent predictors of mortality.

    Evidence of long-term solar variability is reviewed, including historical data and the tree-ring record of radiocarbon. Epochs of suppressed activity like the Maunder Minimum are shown to be frequent occurences of the last several thousand years, but without no obvious period of recurrence. Weak evidence exists for the 11-year cycle as early as Medieval times, although with insufficient accuracy to establish long-term phase stability. (orig.)

    The treatment for pediatric craniopharyngioma remains challenging and controversial. Although this tumor is histologically benign, the treatments include radical surgery, conservative surgery, radiotherapy, intracystic chemotherapy and multimodality approaches. In addition, the long-term functional outcomes including visual function, endocrine function, cognitive function, hypothalamic function, and quality of life are complex and major problems among survivors. In this paper, we reviewed the recent treatments for pediatric craniopharyngioma and the long-term outcomes after treatment in literatures. (author)

    2013-04-01

    To describe adverse event reporting processes in long-term care facilities in the Czech Republic. Prospective cohort study involving a written questionnaire followed by in-person structured interviews with selected respondents. Long-term care facilities located in the Czech Republic. Staff of 111 long-term care facilities (87% of long-term care facilities in the Czech Republic). None. Sixty-three percent of long-term health-care facilities in the Czech Republic have adverse event-reporting processes already established, but these were frequently very immature programs sometimes consisting only of paper recording of incidents. Compared to questionnaire responses, in-person interview responses only partially tended to confirm the results of the written survey. Twenty-one facilities (33%) had at most 1 unconfirmed response, 31 facilities (49%) had 2 or 3 unconfirmed responses and the remaining 11 facilities (17%) had 4 or more unconfirmed responses. In-person interviews suggest that use of a written questionnaire to assess the adverse event-reporting process may have limited validity. Staff of the facilities we studied expressed an understanding of the importance of adverse event reporting and prevention, but interviews also suggested a lack of knowledge necessary for establishing a good institutional reporting system in long-term care.

  12. Changing incentives for long-term gas contracts

    Bohi, D.R.

    1992-01-01

    There is much concern about the absence of long-term gas contracts with fixed price and quantity conditions, which until recent years was the standard way of doing business in the gas industry. These types of contracts performed a valuable service in the development of the gas industry, and there comparative absence today is sometimes thought to be one reason for the current malaise in the industry. One hears the argument that there must be some kind of 'market failure' that prevents buyers and sellers from entering into these long term arrangements, and recent changes in state and federal regulations are often cited as the cause of the problem. The purpose of the author's remarks is to argue that what is taken as a breakdown in the market may be simply a reaction to a decline in economic incentives to enter into long-term contracts with rigid price and quantity terms. This is, in other words, simply one more aspect of change in the gas business that Frank Heintz referred to in his opening remarks this morning. The author starts by giving a brief description of the motives for engaging in long-term contracts, and then describes how incentives to use long-term contracts have declined for both gas buyers and gas sellers. He concludes that the decline in the use of long-term contracts is not cause for regulatory concern, but a result of the continuing transformation of the gas business to one that more closely resembles other commodity markets

    Orthostatic tremor is a rare condition characterised by high-frequency tremor that appears on standing. Although the essential clinical features of orthostatic tremor are well established, little is known about the natural progression of the disorder. We report the long-term outcome based on the largest multicentre cohort of patients with orthostatic tremor. Clinical information of 68 patients with clinical and electrophysiological diagnosis of orthostatic tremor and a minimum follow-up of 5 years is presented. There was a clear female preponderance (76.5%) with a mean age of onset at 54 years. Median follow-up was 6 years (range 5-25). On diagnosis, 86.8% of patients presented with isolated orthostatic tremor and 13.2% had additional neurological features. At follow-up, seven patients who initially had isolated orthostatic tremor later developed further neurological signs. A total 79.4% of patients reported worsening of orthostatic tremor symptoms. These patients had significantly longer symptom duration than those without reported worsening (median 15.5 vs 10.5 years, respectively; p=0.005). There was no change in orthostatic tremor frequency over time. Structural imaging was largely unremarkable and dopaminergic neuroimaging (DaTSCAN) was normal in 18/19 cases. Pharmacological treatments were disappointing. Two patients were treated surgically and showed improvement. Orthostatic tremor is a progressive disorder with increased disability although tremor frequency is unchanged over time. In most cases, orthostatic tremor represents an isolated syndrome. Drug treatments are unsatisfactory but surgery may hold promise. Published by the BMJ Publishing Group Limited.

  14. Long term socio-ecological research across temporal and spatial scales

    Long term socio-ecological research across temporal and spatial scales Simron Jit Singh and Helmut Haberl Institute of Social Ecology, Vienna, Austria Understanding trajectories of change in coupled socio-ecological (or human-environment) systems requires monitoring and analysis at several spatial and temporal scales. Long-term ecosystem research (LTER) is a strand of research coupled with observation systems and infrastructures (LTER sites) aimed at understanding how global change affects ecosystems around the world. In recent years it has been increasingly recognized that sustainability concerns require extending this approach to long-term socio-ecological research, i.e. a more integrated perspective that focuses on interaction processes between society and ecosystems over longer time periods. Thus, Long-Term Socio-Ecological Research, abbreviated LTSER, aims at observing, analyzing, understanding and modelling of changes in coupled socio-ecological systems over long periods of time. Indeed, the magnitude of the problems we now face is an outcome of a much longer process, accelerated by industrialisation since the nineteenth century. The paper will provide an overview of a book (in press) on LTSER with particular emphasis on 'socio-ecological transitions' in terms of material, energy and land use dynamics across temporal and spatial scales.

  15. Long-term cognitive impairment after first-ever ischemic stroke in young adults.

    Up to 14% of all ischemic strokes occur in young adults (young stroke, especially not on the long term. This long-term perspective is important because young patients have a long life expectancy during which they start forming a family, have an active social life, and make decisive career moves. We aimed to evaluate the long-term cognitive outcome. All consecutive patients between January 1, 1980, and November 1, 2010, with a first-ever young ischemic stroke were recruited for cognitive assessment, using a matched stroke-free population as a reference. Composite Z scores for 7 cognitive domains were calculated and the ANCOVA model was used (Bonferroni correction). A below average performance was defined as >1.0 SD below the age-adjusted mean of the controls and cognitive impairment as >1.5 SD. Two hundred seventy-seven patients and 146 matched controls completed cognitive assessment (mean follow-up, 11.0 years, SD, 8.2; age, 50.9 years, SD, 10.3). Long-term cognitive outcome after an ischemic stroke was worse in most cognitive domains compared with a nonstroke population. Up to 50% of the patients had a below average performance or cognitive impairment. Deficits in processing speed, working memory, and attention were most common. Even 11 years after ischemic stroke in young adults, a substantial proportion of patients must cope with permanent cognitive deficits. These results have implications for information given to patients and rehabilitation services.

  16. Does stress remove the HDAC brakes for the formation and persistence of long-term memory?

    White, André O; Wood, Marcelo A

    2014-07-01

    It has been known for numerous decades that gene expression is required for long-lasting forms of memory. In the past decade, the study of epigenetic mechanisms in memory processes has revealed yet another layer of complexity in the regulation of gene expression. Epigenetic mechanisms do not only provide complexity in the protein regulatory complexes that control coordinate transcription for specific cell function, but the epigenome encodes critical information that integrates experience and cellular history for specific cell functions as well. Thus, epigenetic mechanisms provide a unique mechanism of gene expression regulation for memory processes. This may be why critical negative regulators of gene expression, such as histone deacetylases (HDACs), have powerful effects on the formation and persistence of memory. For example, HDAC inhibition has been shown to transform a subthreshold learning event into robust long-term memory and also generate a form of long-term memory that persists beyond the point at which normal long-term memory fails. A key question that is explored in this review, from a learning and memory perspective, is whether stress-dependent signaling drives the formation and persistence of long-term memory via HDAC-dependent mechanisms.

    Full Text Available Abstract Background This study aims to describe the development, testing and optimization of a new standard instrument, the Consumer Quality Index (CQ-index® Long-term Care, for measuring client experiences with long-term care in the Netherlands. Methods Three versions of the CQ-index questionnaires and protocols for study sampling and data collection were developed, designed for interviews with residents of nursing or residential care homes and postal surveys among representatives of psychogeriatric residents and homecare clients. From July to November 2006 a pilot study was conducted among 2,697 clients of 68 nursing or residential care homes, 2,164 representatives of clients in 57 psychogeriatric care institutions, and 1,462 clients of 19 homecare organizations. We performed psychometric analyses and descriptive analyses, and evaluated the pilot study. Results The pilot study showed the feasibility and usability of the instruments, supported the multidimensionality of the questionnaires and showed first findings on client experiences and possibilities for quality improvement. Nine scales applied to all care settings: shared decision making, attitude and courtesy, information, body care, competence and safety of care, activities, autonomy, mental well-being, and availability of personnel. The pilot resulted in three optimized questionnaires and recommendations for nationwide implementation. Conclusions The CQ-index® Long-term Care provides a good basis to investigate the quality of nursing homes, residential care homes and homecare from the clients' perspective. This standardized instrument enables a nationwide comparison of the quality of long-term care for the purpose of transparency and quality assurance.
