    This report is the third in a series concerned with the annual genetically significant dose to the population of Great Britain from diagnostic radiology. It combines information from a frequency survey of diagnostic radiological examinations carried out in Great Britain in 1977 and estimates of gonadal doses for different examination types, together with population and child expectancy data. The annual genetically significant dose from diagnostic radiology carried out in Great Britain in 1977, is estimated to 118 μGy (11.8 millirad) of which 113 μGy (11.3 millirad) is contributed by diagnostic radiology carried out in National Health Service hospitals. There has been a sharp fall in the contribution from obstetric examinations since 1957 when the last national survey was carried out. The contribution from most other examination types is broadly similar and there is little evidence of a change in the overall level of genetically significant dose. This is in spite of an increase in the frequency of radiological examinations per thousand of the population of about 50 per cent. No significant differences were found as between England, Scotland and Wales. The British figure compares favourably with the levels of GSD reported from other countries with developed radiological services. (author)

  2. Best Practices for Wind Energy Development in the Great Lakes Region

    2011-07-19

    This report offers a menu of 18 different, yet complementary, preferred practices and policies. The best practices cover all phases of the wind energy development process - from the policies that allow for wind development, to the sustainable operation of a wind project, to the best practices for decommissioning a spent turbine - including applications for offshore wind. Each best practice describes the opportunities and challenges (pros and cons), and offers a case example that illustrates how that best practice is being utilized by a particular jurisdiction or wind project. The practices described in this publication were selected by a diverse group of interests from the Great Lakes Wind Collaborative that included environmental groups, industry, academia, and federal, state and local government regulators. The practices were identified through a year-long process that included a literature review, online survey and interviews with individuals from the public, private and non-profit sectors. Optimally, a suite of these best practices would be applied in an appropriate combination to fit the conditions of a particular wind project or a set of wind projects within a given locality or region.

    This document offers a menu of 18 different, yet complimentary preferred practices and policies. The best practices cover all phases of the wind energy development process - from the policies that allow for wind development, to the sustainable operation of a wind project, to the best practices for decommissioning a spent turbine - including applications for offshore wind. The practices include those that have been previously tested and proven effective, as well as new practices that were identified by experts in the field as needed for future wind developments. Each best practice includes information about the opportunities and challenges (pros and cons), and offers a case example that illustrates how that best practice is being utilized by a particular jurisdiction or wind project. The practices described in this publication were selected by a diverse group of interests from the Great Lakes Wind Collaborative that included environmental groups, industry, and federal, state and local government regulators.

    Polyethylene passive samplers (PEs) were used to measure concentrations of gaseous and dissolved polycyclic aromatic hydrocarbons (PAHs) in the air and water throughout the lower Great Lakes during summer and fall of 2011. Atmospheric Σ15PAH concentrations ranged from 2.1 ng/m3 in Cape Vincent (NY) to 76.4 ng/m3 in downtown Cleveland (OH). Aqueous Σ18PAH concentrations ranged from 2.4 ng/L at an offshore Lake Erie site to 30.4 ng/L in Sheffield Lake (OH). Gaseous PAH concentrations correlated strongly with population within 3-40 km of the sampling site depending on the compound considered, suggesting that urban centers are a primary source of gaseous PAHs (except retene) in the lower Great Lakes region. The significance of distant population (within 20 km) versus local population (within 3 km) increased with subcooled liquid vapor pressure. Most dissolved aqueous PAHs did not correlate significantly with population, nor were they consistently related to river discharge, wastewater effluents, or precipitation. Air-water exchange calculations implied that diffusive exchange was a source of phenanthrene to surface waters, while acenaphthylene volatilized out of the lakes. Comparison of air-water fluxes with temperature suggested that the significance of urban centers as sources of dissolved PAHs via diffusive exchange may decrease in warmer months.

    The low reproducibility of findings within the scientific literature is a growing concern. This may be due to many findings being false positives which, in turn, can misdirect research effort and waste money. We review factors that may contribute to poor study reproducibility and an excess of 'significant' findings within the published literature. Specifically, we consider the influence of current incentive structures and the impact of these on research practices. The prevalence of false positives within the literature may be attributable to a number of questionable research practices, ranging from the relatively innocent and minor (e.g. unplanned post-hoc tests) to the calculated and serious (e.g. fabrication of data). These practices may be driven by current incentive structures (e.g. pressure to publish), alongside the preferential emphasis placed by journals on novelty over veracity. There are a number of potential solutions to poor reproducibility, such as new publishing formats that emphasize the research question and study design, rather than the results obtained. This has the potential to minimize significance chasing and non-publication of null findings. Significance chasing, questionable research practices and poor study reproducibility are the unfortunate consequence of a 'publish or perish' culture and a preference among journals for novel findings. It is likely that top-down change implemented by those with the ability to modify current incentive structure (e.g. funders and journals) will be required to address problems of poor reproducibility. © 2014 Society for the Study of Addiction.

  9. The significance of routines in nursing practice.

    The aim of this study was to illuminate the significance of routines in nursing practice. Clinical nursing is performed under the guidance of routines to varying degrees. In the nursing literature, routine is described as having both negative and positive aspects, but use of the term is inconsistent, and empirical evidence is sparse. In the research on organisational routines, a distinction is made between routine as a rule and routine as action. A qualitative design using a phenomenological-hermeneutic approach. Data collection from three focus groups focused on nurses' experience of routines. Seventeen individual interviews from a previous study focusing on caring culture were also analysed in a secondary qualitative analysis. All participants were employed as 'qualified nursing pool' nurses. Routines are experienced as pragmatic, obstructive and meaningful. The aim of the pragmatic routine was to ensure that daily working life works; this routine is practised more on the basis of rational arguments and obvious intentions. The obstructive routine had negative consequences for nursing practice and was described as nursing losing its humanity and violating the patient's integrity. The meaningful routine involved becoming one with the routine and for the nurses, it felt right and meaningful to adapt to it. Routines become meaningful when the individual action is in harmony with the cultural pattern on which the nursing work is based. Instead of letting contemporary practice passively become routine, routines can be assessed and developed using research and theoretical underpinnings as a starting point for nursing practice. Leaders have a special responsibility to develop and support meaningful routines. One approach could be to let wards examine their routines from a patient perspective on the basis of the themes of pragmatic, meaningful and obstructive routine. © 2010 Blackwell Publishing Ltd.

    OBJECTIVE: Caesarean section is one of the most commonly performed major operations on women worldwide. Operative morbidity includes haemorrhage, anaemia, blood transfusion and in severe cases, maternal death. Various clinical guidelines address oxytocin use at the time of caesarean section. We previously reported wide variation in practice amongst clinicians in the United Kingdom in the use of oxytocin at caesarean section. The aim of this current study was to determine whether the variation in approach is universal across the individual countries of Great Britain and Ireland and whether this reflects differences in interpretation and implementation of clinical practice guidelines. STUDY DESIGN: We conducted a survey of practice in the five individual countries of Great Britain and Ireland. A postal questionnaire was sent to all lead consultant obstetricians and anaesthetists with responsibility for the labour ward. We explored the use of oxytocin bolus and infusion, the measurement of blood loss at caesarean section and the rates of major haemorrhage. Existing clinical guidelines from the National Institute for Clinical Excellence (NICE), the Royal College of Obstetricians and Gynaecologists (RCOG) and ALSO (Advanced Life Support in Obstetrics) were used to benchmark reported practice against recommended practice for the management of blood loss at caesarean section. RESULTS: The response rate was 82% (391 respondents). Use of a 5 IU oxytocin bolus was reported by 346 respondents (85-95% for individual countries). In some countries, up to 14% used a 10 IU oxytocin bolus despite recommendations against this. Routine use of an oxytocin infusion varied greatly between countries (11% lowest-55% highest). Marked variations in choice of oxytocin regimens were noted with inconsistencies in the country-specific recommendations, e.g. NICE (which covers England and Wales) recommends a 30 IU oxytocin infusion over 4h, but only 122 clinicians (40%) used this.

    Background On March 11, 2011, a massive undersea earthquake and tsunami struck East Japan. Few studies have investigated the impact of exposure to a natural disaster on preschool children. We investigated the association of trauma experiences during the Great East Japan Earthquake on clinically significant behavior problems among preschool children 2 years after the earthquake. Method Participants were children who were exposed to the 2011 disaster at preschool age (affected area, n = 178; unaffected area, n = 82). Data were collected from September 2012 to June 2013 (around 2 years after the earthquake), thus participants were aged 5 to 8 years when assessed. Severe trauma exposures related to the earthquake (e.g., loss of family members) were assessed by interview, and trauma events in the physical environment related to the earthquake (e.g. housing damage), and other trauma exposure before the earthquake, were assessed by questionnaire. Behavior problems were assessed by caregivers using the Child Behavior Checklist (CBCL), which encompasses internalizing, externalizing, and total problems. Children who exceeded clinical cut-off of the CBCL were defined as having clinically significant behavior problems. Results Rates of internalizing, externalizing, and total problems in the affected area were 27.7%, 21.2%, and 25.9%, respectively. The rate ratio suggests that children who lost distant relatives or friends were 2.36 times more likely to have internalizing behavior problems (47.6% vs. 20.2%, 95% CI: 1.10–5.07). Other trauma experiences before the earthquake also showed significant positive association with internalizing, externalizing, and total behavior problems, which were not observed in the unaffected area. Conclusions One in four children still had behavior problems even 2 years after the Great East Japan Earthquake. Children who had other trauma experiences before the earthquake were more likely to have behavior problems. These data will be

  15. Theoretical and practical significance of formal reasoning

    Science.gov (United States)

    Linn, Marcia C.

    Piaget's theory has profoundly influenced science education research. Following Piaget, researchers have focused on content-free strategies, developmentally based mechanisms, and structural models of each stage of reasoning. In practice, factors besides those considered in Piaget's theory influence whether or not a theoretically available strategy is used. Piaget's focus has minimized the research attention placed on what could be called practical factors in reasoning. Practical factors are factors that influence application of a theoretically available strategy, for example, previous experience with the task content, familiarity with task instructions, or personality style of the student. Piagetian theory has minimized the importance of practical factors and discouraged investigation of (1) the role of factual knowledge in reasoning, (2) the diagnosis of specific, task-based errors in reasoning, (3) the influence of individual aptitudes on reasoning (e.g., field dependence-independence), and (4) the effect of educational interventions designed to change reasoning. This article calls for new emphasis on practical factors in reasoning and suggests why research on practical factors in reasoning will enhance our understanding of how scientific reasoning is acquired and of how science education programs can foster it.

  18. Determination of significance in Ecological Impact Assessment: Past change, current practice and future improvements

    Ecological Impact Assessment (EcIA) is an important tool for conservation and achieving sustainable development. 'Significant' impacts are those which disturb or alter the environment to a measurable degree. Significance is a crucial part of EcIA, our understanding of the concept in practice is vital if it is to be effective as a tool. This study employed three methods to assess how the determination of significance has changed through time, what current practice is, and what would lead to future improvements. Three data streams were collected: interviews with expert stakeholders, a review of 30 Environmental Statements and a broad-scale survey of the United Kingdom Institute of Ecology and Environmental Management (IEEM) members. The approach taken in the determination of significance has become more standardised and subjectivity has become constrained through a transparent framework. This has largely been driven by a set of guidelines produced by IEEM in 2006. The significance of impacts is now more clearly justified and the accuracy with which it is determined has improved. However, there are limitations to accuracy and effectiveness of the determination of significance. These are the quality of baseline survey data, our scientific understanding of ecological processes and the lack of monitoring and feedback of results. These in turn are restricted by the limited resources available in consultancies. The most notable recommendations for future practice are the implementation of monitoring and the publication of feedback, the creation of a central database for baseline survey data and the streamlining of guidance. - Highlights: Black-Right-Pointing-Pointer The assessment of significance has changed markedly through time. Black-Right-Pointing-Pointer The IEEM guidelines have driven a standardisation of practice. Black-Right-Pointing-Pointer Currently limited by quality of baseline data and scientific understanding.

  1. Impromptu: great impromptu speaking is never just impromptu

    2015-10-01

    Full Text Available Great impromptu speaking, reciting and singing are never just an isolated impromptu act. It is the result of endless practice to perfect performance that can then be given impromptu. One of the main objectives of learning English as a Second Language (ESL is to be able to speak English impromptu, not just on the stage or in front of an audience but also in a casual meeting, on the street or during a formal meeting in a board-room. In fact to be able to speak “impromptu” should be the Holy Grail of teaching and learning ESL, more important than reading, writing and listening. So how come it is not given the priority it deserves – and how come it seems such a difficult goal? We believe it is because teachers and learners neglect to emphasize and practice the key to learning impromptu speaking. That key we believe is practice, practice and more practice. We can remember songs from our kindergarten years and we can still sing them because we practiced, practiced and practiced them. We believe that the teaching of ESL often overlooks the critical importance of lots of practice to create depth of learning and that creative methods of practicing need to be taught and practiced in ESL courses until such methods become deeply habitual, in fact they become a new personal paradigm. If our students aim to become great at ESL, they, too, must take continuous never-ending practice to heart.

    Understanding the distribution and determinants of disease in animal populations must be underpinned by knowledge of animal demographics. For companion animals, these data have been difficult to collect because of the distributed nature of the companion animal veterinary industry. Here we describe key demographic features of a large veterinary-visiting pet population in Great Britain as recorded in electronic health records, and explore the association between a range of animal's characteristics and socioeconomic factors. Electronic health records were captured by the Small Animal Veterinary Surveillance Network (SAVSNET), from 143 practices (329 sites) in Great Britain. Mixed logistic regression models were used to assess the association between socioeconomic factors and species and breed ownership, and preventative health care interventions. Dogs made up 64.8% of the veterinary-visiting population, with cats, rabbits and other species making up 30.3, 2.0 and 1.6% respectively. Compared to cats, dogs and rabbits were more likely to be purebred and younger. Neutering was more common in cats (77.0%) compared to dogs (57.1%) and rabbits (45.8%). The insurance and microchipping relative frequency was highest in dogs (27.9 and 53.1%, respectively). Dogs in the veterinary-visiting population belonging to owners living in least-deprived areas of Great Britain were more likely to be purebred, neutered, insured and microchipped. The same association was found for cats in England and for certain parameters in Wales and Scotland. The differences we observed within these populations are likely to impact on the clinical diseases observed within individual veterinary practices that care for them. Based on this descriptive study, there is an indication that the population structures of companion animals co-vary with human and environmental factors such as the predicted socioeconomic level linked to the owner's address. This 'co-demographic' information suggests that further

  6. Won-Buddhism and a Great Turning in Civilization: The Role of Religion

    Directory of Open Access Journals (Sweden)

    Paik Nak-chung

    2017-03-01

    Full Text Available Addressing the theme of a great turning in civilization, this essay focuses on the Korean religion Won-Buddhism with its founding motto, “With this Great Opening of matter, let there be a Great Opening of spirit.” Both its doctrine and practice arguably possess great potential. Unlike the traditional Buddhist view of enlightenment, Won-Buddhism’s “Great Opening of spirit” starts from a specific diagnosis of the current time as an age of “Great Opening of matter” and proposes a double project of at once adapting to and overcoming modernity. In this way, it carries on the tradition of Korea’s indigenous religious movements since the mid-nineteenth century, but by combining that strain with Buddhism as its core doctrine, it achieves a fuller global significance than its predecessors. The essay examines Roberto Unger’s The Religion of the Future for both parallels and divergences, sympathizing with Unger’s emphasis on a religious revolution, but finding his thought essentially confined within the limits of Western metaphysics. Martin Heidegger is brought in to elucidate this point, as is Karl Marx, for comparison and contrast with Won-Buddhism’s diagnosis of and response to modernity. In closing, the essay takes up two Won-Buddhist agendas that are also of global concern: gender equality and the “church and state” relation.

  9. Distinguishing between statistical significance and practical/clinical meaningfulness using statistical inference.

    2014-03-01

    Decisions about support for predictions of theories in light of data are made using statistical inference. The dominant approach in sport and exercise science is the Neyman-Pearson (N-P) significance-testing approach. When applied correctly it provides a reliable procedure for making dichotomous decisions for accepting or rejecting zero-effect null hypotheses with known and controlled long-run error rates. Type I and type II error rates must be specified in advance and the latter controlled by conducting an a priori sample size calculation. The N-P approach does not provide the probability of hypotheses or indicate the strength of support for hypotheses in light of data, yet many scientists believe it does. Outcomes of analyses allow conclusions only about the existence of non-zero effects, and provide no information about the likely size of true effects or their practical/clinical value. Bayesian inference can show how much support data provide for different hypotheses, and how personal convictions should be altered in light of data, but the approach is complicated by formulating probability distributions about prior subjective estimates of population effects. A pragmatic solution is magnitude-based inference, which allows scientists to estimate the true magnitude of population effects and how likely they are to exceed an effect magnitude of practical/clinical importance, thereby integrating elements of subjective Bayesian-style thinking. While this approach is gaining acceptance, progress might be hastened if scientists appreciate the shortcomings of traditional N-P null hypothesis significance testing.

  11. What great managers do.

    Science.gov (United States)

    Buckingham, Marcus

    2005-03-01

    Much has been written about the qualities that make a great manager, but most of the literature overlooks a fundamental question: What does a great manager actually do? While there are countless management styles, one thing underpins the behavior of all great managers. Above all, an exceptional manager comes to know and value the particular quirks and abilities of her employees. She figures out how to capitalize on her staffers' strengths and tweaks her environment to meet her larger goals. Such a specialized approach may seem like a lot of work. But in fact, capitalizing on each person's uniqueness can save time. Rather than encourage employees to conform to strict job descriptions that may include tasks they don't enjoy and aren't good at, a manager who develops positions for his staff members based on their unique abilities will be rewarded with behaviors that are far more efficient and effective than they would be otherwise. This focus on individuals also makes employees more accountable. Because staffers are evaluated on their particular strengths and weaknesses, they are challenged to take responsibility for their abilities and to hone them. Capitalizing on a person's uniqueness also builds a stronger sense of team. By taking the time to understand what makes each employee tick, a great manager shows that he sees his people for who they are. This personal investment not only motivates individuals but also galvanizes the entire team. Finally, this approach shakes up existing hierarchies, which leads to more creative thinking. To take great managing from theory to practice, the author says, you must know three things about a person: her strengths, the triggers that activate those strengths, and how she learns. By asking the right questions, squeezing the right triggers, and becoming aware of your employees' learning styles, you will discover what motivates each person to excel.

Comparing the Great Recession with the 1980s recession it is concluded that there is a

  14. Energy and water in the Great Lakes.

    The nexus between thermoelectric power production and water use is not uniform across the U.S., but rather differs according to regional physiography, demography, power plant fleet composition, and the transmission network. That is, in some regions water demand for thermoelectric production is relatively small while in other regions it represents the dominate use. The later is the case for the Great Lakes region, which has important implications for the water resources and aquatic ecology of the Great Lakes watershed. This is today, but what about the future? Projected demographic trends, shifting lifestyles, and economic growth coupled with the threat of global climate change and mounting pressure for greater U.S. energy security could have profound effects on the region's energy future. Planning for such an uncertain future is further complicated by the fact that energy and environmental planning and regulatory decisionmaking is largely bifurcated in the region, with environmental and water resource concerns generally taken into account after new energy facilities and technologies have been proposed, or practices are already in place. Based on these confounding needs, the objective of this effort is to develop Great Lakes-specific methods and tools to integrate energy and water resource planning and thereby support the dual goals of smarter energy planning and development, and protection of Great Lakes water resources. Guiding policies for this planning are the Great Lakes and St. Lawrence River Basin Water Resources Compact and the Great Lakes Water Quality Agreement. The desired outcome of integrated energy-water-aquatic resource planning is a more sustainable regional energy mix for the Great Lakes basin ecosystem.

    Full Text Available Aiming at the problem of navigation error caused by unified earth model in great circle route planning using sphere model and modern navigation equipment using ellipsoid mode, a method of great ellipse route planning based on space vector is studied. By using space vector algebra method, the vertex of great ellipse is solved directly, and description of great ellipse based on major-axis vector and minor-axis vector is presented. Then calculation formulas of great ellipse azimuth and distance are deduced using two basic vectors. Finally, algorithms of great ellipse route planning are studied, especially equal distance route planning algorithm based on Newton-Raphson(N-R method. Comparative examples show that the difference of route planning between great circle and great ellipse is significant, using algorithms of great ellipse route planning can eliminate the navigation error caused by the great circle route planning, and effectively improve the accuracy of navigation calculation.

    The term tumor markers include a spectrum of molecules and substances with widely divergent characteristics whose presence in the significant amount can be related to the malignant disease. An ideal tumor marker should have high specificity and sensitivity, which would allow its use in early diagnosis and prognosis of malignant disease, as well as in prediction of therapeutic response and follow-up of the patients. Numerous biochemical entities have emerged as potentially valuable tumor markers so far, but only few markers showed to be of considerable clinical reliability and have been accepted into standard clinical practice. Recent development of genomics and proteomics has enabled the examination of many new potential tumor markers. Scientific studies on discovery, development, and application of tumor markers have been proceeding quite rapidly providing great opportunities for improving the management of cancer patients. This review is focusing on the clinical usefulness of various tumor markers already in clinical practice as well as certain potential markers, giving a brief description of their prognostic and predictive significance in most common malignancies.

    OBJECTIVE To determine the prevalence of unrecognized lower extremity peripheral arterial disease (PAD) among men and women aged 55 years and older in a general internal medicine (GIM) practice and to identify characteristics and functional performance associated with unrecognized PAD. DESIGN Cross-sectional. SETTING Academic medical center. PARTICIPANTS We identified 143 patients with known PAD from the noninvasive vascular laboratory, and 239 men and women aged 55 and older with no prior PAD history from a GIM practice. Group 1 consisted of patients with PAD consecutively identified from the noninvasive vascular laboratory (n = 143). Group 2 included GIM practice patients found to have an ankle brachial index less than 0.90, consistent with PAD (n = 34). Group 3 consisted of GIM practice patients without PAD (n = 205). MEASUREMENTS AND MAIN RESULTS Leg functioning was assessed with the 6-minute walk, 4-meter walking velocity, and Walking Impairment Questionnaire (WIQ). Of GIM practice patients, 14% had unrecognized PAD. Only 44% of patients in Group 2 had exertional leg symptoms. Distances achieved in the 6-minute walk were 1,130, 1,362, and 1,539 feet for Groups 1, 2, and 3, respectively, adjusting for age, gender, and race (P < .001). The degree of difficulty walking due to leg symptoms as reported on the WIQ was comparable between Groups 2 and 3 and significantly greater in Group 1 than Group 2. In multiple logistic regression analysis including Groups 2 and 3, current cigarette smoking was associated independently with unrecognized PAD (odds ratio [OR], 6.82; 95% confidence interval [95% CI], 1.55 to 29.93). Aspirin therapy was nearly independently associated with absence of PAD (OR, 0.37; 95% CI, 0.12 to 1.12). CONCLUSION Unrecognized PAD is common among men and women aged 55 years and older in GIM practice and is associated with impaired lower extremity functioning. Ankle brachial index screening may be necessary to diagnose unrecognized PAD in a GIM

  19. The practicality of defensive ice walls: How would the great ice wall in Game of Thrones hold up?

    Truffer, M.

    2017-12-01

    The Game of Thrones great ice wall is a colossal feature stretching several hundred miles and over 200 m high. Its purpose is to defend the realm from the wildlings. It is generally pictured as a near vertical wall. An ice wall of these proportions poses interesting challenges, mainly because ice acts as a non-linear shear-thinning fluid. A 200 m high vertical wall would create a large effective stress near its base of almost 1.8 MPa. Typical stresses responsible for ice flow in glaciers and ice sheets are more than a magnitude lower (0.1 MPa). Extrapolating a commonly used flow law for temperate ice to such high stresses would lead to strain rates at the bottom of the wall in excess of 1/day, meaning the wall would rapidly collapse and spread laterally under its own weight. To keep the wall stable, it would help to cool it significantly, as the flow of ice is also very temperature dependent. Cooling to a chilly -40 C would reduce strain rates by two orders of magnitude, but this still leads to significant slumping of the wall within just a few weeks. A time-dependent similarity solution for simplified ice flow equations that describe the evolving shape of the ice wall was provided by Halfar (1981), and demonstrates the rapid decay of the wall. A simple estimate can be derived by assuming that ice is a perfectly plastic fluid, able to maintain a basal shear stress of about 0.1 MPa. A stable ice wall would then spread laterally to about 4 km width. The resulting slope would only be steep at the very margin and the ice wall would loose much of its defensive capabilities. I conclude that the ice wall as proposed would not be a practicable defense under typical Earth conditions, and special magical powers would be necessary to maintain its shape, even for just a few days.

    Treatment of insomnia with acupuncture is taken as an example to explore the significance and problems existed in the present systematic evaluation in establishment of guidance for clinical practice. Fifteen articles on systematic evaluation of both English and Chinese were retrieved and studied carefully, their basic information was analyzed. Through study on the establishing process of the guidance of clinical practice, researches were focused on the possible significance of the articles to the guidance as well as the notes in the reuse of those articles since problem still existed. It is held that the systematic evaluation has great significance on the establishment of the guidance from the aspects of applicable people, recommended standards of diagnosis and therapeutic evaluation, extended recommendation and methodology. Great importance should also be attached to the direct application of the research result and understanding of the evaluation result. The data should be rechecked when necessary. Great guiding function can be found on the systematic evaluation of articles to the guidance. Moreover, if information needed to be taken into a full play, specific analysis should also be done on the concrete research targets.

    Based on the researches of Szydlowski and Krawiec, we studied the inherent complexity of a chaotic business cycle with great excitements in non-resonant condition. First, we got the first-order and second-order approximate solutions of the system by using multiple scale method. Then deduced the formulation reflecting the complex relations between vibration, phase, bifurcation parameter μ and excite frequency Ω of first-order solution. As the great excitement F varied, the global changes of the system solutions were analyzed. We also explored the different paths leading the systems with different parameter combinations into catastrophe region, fuzzy region or chaos region. Finally, we discussed the evolution trends of business cycle models under the above-mentioned conditions. Hence, this paper has some theoretical and practical significance.

  3. Policies and practices of beach monitoring in the Great Lakes, USA: a critical review

    Nevers, Meredith B.; Whitman, Richard L.

    2010-01-01

    Beaches throughout the Great Lakes are monitored for fecal indicator bacteria (typically Escherichia coli) in order to protect the public from potential sewage contamination. Currently, there is no universal standard for sample collection and analysis or results interpretation. Monitoring policies are developed by individual beach management jurisdictions, and applications are highly variable across and within lakes, states, and provinces. Extensive research has demonstrated that sampling decisions for time, depth, number of replicates, frequency of sampling, and laboratory analysis all influence the results outcome, as well as calculations of the mean and interpretation of the results in policy decisions. Additional shortcomings to current monitoring approaches include appropriateness and reliability of currently used indicator bacteria and the overall goal of these monitoring programs. Current research is attempting to circumvent these complex issues by developing new tools and methods for beach monitoring. In this review, we highlight the variety of sampling routines used across the Great Lakes and the extensive body of research that challenges comparisons among beaches. We also assess the future of Great Lakes monitoring and the advantages and disadvantages of establishing standards that are evenly applied across all beaches.

    The mass migration of African Americans out of the South during the first two-thirds of the twentieth century represents one of the most significant internal migration flows in U.S. Those undertaking the Great Migration left the South in search of a better life, and their move transformed the cultural, social, and political dynamics of African American life specifically and U.S. society more generally. Recent research offers conflicting evidence regarding the migrants' success in translating their geographic mobility into economic mobility. Due in part to the lack of a large body of longitudinal data, almost all studies of the Great Migration have focused on the migrants themselves, usually over short periods of their working lives. Using longitudinally linked census data, we take a broader view, investigating the long-term economic and social effects of the Great Migration on the migrants' children. Our results reveal modest but statistically significant advantages in education, income, and poverty status for the African American children of the Great Migration relative to the children of southerners who remained in the South. In contrast, second-generation white migrants experienced few benefits from migrating relative to southern or northern stayers.

    In France, attempts to define common ground during spine surgery meetings have revealed significant variability in clinical practices across different schools of surgery and the two specialities involved in spine surgery, namely, neurosurgery and orthopaedic surgery. To objectively characterise this variability by performing a survey based on a fictitious spine trauma case. Our working hypothesis was that significant variability existed in trauma practices and that this variability was related to a lack of strong scientific evidence in spine trauma care. We performed a cross-sectional survey based on a clinical vignette describing a 31-year-old male with an L1 burst fracture and neurologic symptoms (numbness). Surgeons received the vignette and a 14-item questionnaire on the management of this patient. For each question, surgeons had to choose among five possible answers. Differences in answers across surgeons were assessed using the Index of Qualitative Variability (IQV), in which 0 indicates no variability and 1 maximal variability. Surgeons also received a questionnaire about their demographics and surgical experience. Of 405 invited spine surgeons, 200 responded to the survey. Five questions had an IQV greater than 0.9, seven an IQV between 0.5 and 0.9, and two an IQV lower than 0.5. Variability was greatest about the need for MRI (IQV=0.93), degree of urgency (IQV=0.93), need for fusion (IQV=0.92), need for post-operative bracing (IQV=0.91), and routine removal of instrumentation (IQV=0.94). Variability was lowest for questions about the need for surgery (IQV=0.42) and use of the posterior approach (IQV=0.36). Answers were influenced by surgeon specialty, age, experience level, and type of centre. Clinical practice regarding spine trauma varies widely in France. Little published evidence is available on which to base recommendations that would diminish this variability. Copyright © 2015. Published by Elsevier Masson SAS.

  6. Humans as major geological and geomorphological agents in the Anthropocene: the significance of artificial ground in Great Britain.

    2011-03-13

    Since the first prehistoric people started to dig for stone to make implements, rather than pick up loose material, humans have modified the landscape through excavation of rock and soil, generation of waste and creation of artificial ground. In Great Britain over the past 200 years, people have excavated, moved and built up the equivalent of at least six times the volume of Ben Nevis. It is estimated that the worldwide deliberate annual shift of sediment by human activity is 57,000 Mt (million tonnes) and exceeds that of transport by rivers to the oceans (22,000 Mt) almost by a factor of three. Humans sculpt and transform the landscape through the physical modification of the shape and properties of the ground. As such, humans are geological and geomorphological agents and the dominant factor in landscape evolution through settlement and widespread industrialization and urbanization. The most significant impact of this has been since the onset of the Industrial Revolution in the eighteenth century, coincident with increased release of greenhouse gases to the atmosphere. The anthropogenic sedimentological record, therefore, provides a marker on which to characterize the Anthropocene.

  8. Impact significance determination-Pushing the boundaries

    International Nuclear Information System (INIS)

    Lawrence, David P.

    2007-01-01

    Impact significance determination practice tends to be highly variable. Too often insufficient consideration is given to good practice insights. Also, impact significance determinations are frequently narrowly defined addressing, for example, only individual, negative impacts, focusing on bio-physical impacts, and not seeking to integrate either the Precautionary Principle or sustainability. This article seeks to extend the boundaries of impact significance determination practice by providing an overview of good general impact significance practices, together with stakeholder roles and potential methods for addressing significance determination challenges. Relevant thresholds, criteria, contextual considerations and support methods are also highlighted. The analysis is then extended to address how impact significance determination practices change for positive as compared with negative impacts, for cumulative as compared with individual impacts, for socio-economic as compared with bio-physical impacts, when the Precautionary Principle is integrated into the process, and when sustainability contributions drive the EIA process and related impact significance determinations. These refinements can assist EIA practitioners in ensuring that the scope and nature of impact significance determinations reflect the broadened scope of emerging EIA requirements and practices. Suggestions are included for further refining and testing of the proposed changes to impact significance determination practice

    The Great Recession's influence on American undergraduate students' values was examined, testing Greenfield's and Kasser's theories concerning value development during economic downturns. Study 1 utilised aggregate-level data to investigate (a) population-level value changes between the pre-recession (2004-2006: n = 824,603) and recession freshman cohort (2008-2010: n = 662,262) and (b) overall associations of population-level values with national economic climates over long-term periods by correlating unemployment rates and concurrent aggregate-level values across 1966-2015 (n = 10 million). Study 2 examined individual-level longitudinal value development from freshman to senior year, and whether the developmental trajectories differed between those who completed undergraduate education before the Great Recession (freshmen in 2002, n = 12,792) versus those who encountered the Great Recession during undergraduate years (freshmen in 2006, n = 13,358). Results suggest American undergraduate students' increased communitarianism (supporting Greenfield) and materialism (supporting Kasser) during the Great Recession. The recession also appears to have slowed university students' development of positive self-views. Results contribute to the limited literature on the Great Recession's influence on young people's values. They also offer theoretical and practical implications, as values of this privileged group of young adults are important shapers of societal values, decisions, and policies. © 2016 International Union of Psychological Science.

  10. Artificial propagation of coregonines in the management of the Laurentian Great Lakes

    Science.gov (United States)

    Todd, Thomas N.

    1986-01-01

    Numerous stresses caused wide fluctuations in the abundance of Great Lakes coregonine fishes during the last century. State, Provincial, and Federal agencies attempted to bolster these fisheries by stocking more than 32 billion fry of lake whitefish (Coregonus clupeaformis) and 6 billion fry of lake herring (C. artedii) over a period of about 90 years (1870-1960). Propagation efforts were unsuccessful in arresting the decline of these fishes, perhaps because the stocking densities were too low. It appears that stocking densities must exceed 41% of the natural hatch to produce measurable success in a planting program that augments natural reproduction. Stocking of any of the Great Lakes with lake whitefish at these levels would require several billion fry per lake annually. Such a program is too large to be practical and intensified protection of the remaining stocks would be more cost effective. A species such as the shortnose cisco (C. reighardi) which has only a small number of extant individuals, and can therefore be significantly augmented with fewer stocked fish, may be a much better candidate for propagation than is the lake whitefish. Propagation of coregonines in the Great Lakes should be considered only in localities that have little or no natural recruitment and then only for rehabilitation, and only if accompanied by adequate assessment of the performance of the stocked fish.

    2016-06-01

    Full Text Available Since reading and writing digitally demand partially different competencies, there is a change in some of the premises of related educational practices. This study aims to contribute to the knowledge of educational reading practices by scrutinizing how literacy events evolve in a digital classroom where each student has a personal digital device (1:1, iPads in this study. Our study is grounded in sociocultural theories of learning and focuses on the structuring resources utilized by students, namely the notion of multiple ongoing activities and the ways in which specific resources take precedence in shaping these activities. One class of 13–14 year-old students was studied for a week across several subjects through video-recordings and observations. The findings imply that the students moved among vast array of reading practices. However, the main structuring resource is a strong focus on task-solving and the practice of schooling, which mainly builds on principles emanating from traditional text. It is only occasionally that structuring resources that also include the opportunities associated with digital technology are utilized. This indicates the importance of further studies on how educational practices could be organized to scaffold the basis of traditional reading comprehension as well as other approaches required in digital environments.

  12. The Great Recession, unemployment and suicide.

    2015-02-01

    How have suicide rates responded to the marked increase in unemployment spurred by the Great Recession? Our paper puts this issue into a wider perspective by assessing (1) whether the unemployment-suicide link is modified by the degree of unemployment protection, and (2) whether the effect on suicide of the present crisis differs from the effects of previous economic downturns. We analysed the unemployment-suicide link using time-series data for 30 countries spanning the period 1960-2012. Separate fixed-effects models were estimated for each of five welfare state regimes with different levels of unemployment protection (Eastern, Southern, Anglo-Saxon, Bismarckian and Scandinavian). We included an interaction term to capture the possible excess effect of unemployment during the Great Recession. The largest unemployment increases occurred in the welfare state regimes with the least generous unemployment protection. The unemployment effect on male suicides was statistically significant in all welfare regimes, except the Scandinavian one. The effect on female suicides was significant only in the eastern European country group. There was a significant gradient in the effects, being stronger the less generous the unemployment protection. The interaction term capturing the possible excess effect of unemployment during the financial crisis was not significant. Our findings suggest that the more generous the unemployment protection the weaker the detrimental impact on suicide of the increasing unemployment during the Great Recession.

    Bibliometrics are the methods used to quantitatively analyze scientific literature. In this study, bibliometrics were used to quantify the scientific output of neurosurgical departments throughout Great Britain and Ireland. A list of neurosurgical departments was obtained from the Society of British Neurological Surgeons website. Individual departments were contacted for an up-to-date list of consultant (attending) neurosurgeons practicing in these departments. Scopus was used to determine the h-index and m-quotient for each neurosurgeon. Indices were measured by surgeon and by departmental mean and total. Additional information was collected about the surgeon's sex, title, listed superspecialties, higher research degrees, and year of medical qualification. Data were analyzed for 315 neurosurgeons (25 female). The median h-index and m-quotient were 6.00 and 0.41, respectively. These were significantly higher for professors (h-index 21.50; m-quotient 0.71) and for those with an additional MD or PhD (11.0; 0.57). There was no significant difference in h-index, m-quotient, or higher research degrees between the sexes. However, none of the 16 British neurosurgery professors were female. Neurosurgeons who specialized in functional/epilepsy surgery ranked highest in terms of publication productivity. The 5 top-scoring departments were those in Addenbrooke's Hospital, Cambridge; St. George's Hospital, London; Great Ormond Street Hospital, London; National Hospital for Neurology and Neurosurgery, Queen Square, London; and John Radcliffe Hospital, Oxford. The h-index is a useful bibliometric marker, particularly when comparing between studies and individuals. The m-quotient reduces bias toward established researchers. British academic neurosurgeons face considerable challenges, and women remain underrepresented in both clinical and academic neurosurgery in Britain and Ireland.

  14. The statistical significance of error probability as determined from decoding simulations for long codes

    Science.gov (United States)

    Massey, J. L.

    1976-01-01

    The very low error probability obtained with long error-correcting codes results in a very small number of observed errors in simulation studies of practical size and renders the usual confidence interval techniques inapplicable to the observed error probability. A natural extension of the notion of a 'confidence interval' is made and applied to such determinations of error probability by simulation. An example is included to show the surprisingly great significance of as few as two decoding errors in a very large number of decoding trials.

    In the organizations in the face of unexpected events in the 2011 Great East Japan Earthquake, the organizational behavior which was coped with by their members was seen. It is important to prepare emergency that the backgrounds of those organizational behavior were understood. This study aimed to explore the factors that contribute to the practice of organizational behavior as coping with unexpected events through the case survey of the Great East Japan Earthquake. This study carried out literature survey and interview survey of personnel in charge of disaster prevention, BCP in the 10 organizations which coped with the earthquake. As the result, the following two outcomes were obtained. 1) Factors that contribute to the practice of the 13 kinds of the organizational behavior were clarified. 2) Discussion from the view point of the factors classification indicated the importance of the factors which are classified into normal business and features of organization.

    Due to the increasing lack of physicians, an ageing and thus multi-morbid society and a misdistribution of physicians in Germany primary care provided by general practitioners is at risk. Therefore, approaches to recruit more physicians for general practice are being sought. The aim of the present study was to explore individual motivations for choosing a career in general practice, vocational trainees' perspectives on the current situation of vocational training and to identify possible approaches to improve the situation with suggestions from vocational trainees in Germany. A qualitative study was conducted by interviewing 13 trainees. The interviews that were based on a predefined interview guideline were recorded and transcribed. The analysis was performed according to Mayring supported by the software Atlas.ti. In general, the reasons given for choosing general practice include the holistic view towards patients, the opportunity to see the direct impact of therapies and self-employment. Furthermore, general practice was perceived as a job with a positive work-life balance. Barriers to vocational training are the lack of structure of individual rotations and the low salaries during the rotation in practice. Furthermore, the basic conditions for working as a self-employed general practitioner in Germany were described as being a disincentive. A general suggestion for improvement was to promote professional recognition of general practice at universities. A qualification of vocational trainers was requested. Specific suggestions were: better payment, better-structured rotations and a specific preparation for the self-employed general practitioner. The results of this study reveal that a single measure is insufficient for recruiting more young doctors for general practice. In fact, a package of measures is necessary to improve aspects of the vocational training but also general conditions for the profession. Copyright © 2010. Published by Elsevier GmbH.

  20. Great Apes

    2014-01-01

    Anesthesia of great apes is often necessary to conduct diagnostic analysis, provide therapeutics, facilitate surgical procedures, and enable transport and translocation for conservation purposes. Due to the stress of remote delivery injection of anesthetic agents, recent studies have focused on oral delivery and/or transmucosal absorption of preanesthetic and anesthetic agents. Maintenance of the airway and provision of oxygen is an important aspect of anesthesia in great ape species. The provision of analgesia is an important aspect of the anesthesia protocol for any procedure involving painful stimuli. Opioids and nonsteroidal anti-inflammatory drugs (NSAIDs) are often administered alone, or in combination to provide multi-modal analgesia. There is increasing conservation management of in situ great ape populations, which has resulted in the development of field anesthesia techniques for free-living great apes for the purposes of translocation, reintroduction into the wild, and clinical interventions.

  1. Modelling psychological responses to the Great East Japan earthquake and nuclear incident.

    Full Text Available The Great East Japan (Tōhoku/Kanto earthquake of March 2011 was followed by a major tsunami and nuclear incident. Several previous studies have suggested a number of psychological responses to such disasters. However, few previous studies have modelled individual differences in the risk perceptions of major events, or the implications of these perceptions for relevant behaviours. We conducted a survey specifically examining responses to the Great Japan earthquake and nuclear incident, with data collected 11-13 weeks following these events. 844 young respondents completed a questionnaire in three regions of Japan; Miyagi (close to the earthquake and leaking nuclear plants, Tokyo/Chiba (approximately 220 km from the nuclear plants, and Western Japan (Yamaguchi and Nagasaki, some 1000 km from the plants. Results indicated significant regional differences in risk perception, with greater concern over earthquake risks in Tokyo than in Miyagi or Western Japan. Structural equation analyses showed that shared normative concerns about earthquake and nuclear risks, conservation values, lack of trust in governmental advice about the nuclear hazard, and poor personal control over the nuclear incident were positively correlated with perceived earthquake and nuclear risks. These risk perceptions further predicted specific outcomes (e.g. modifying homes, avoiding going outside, contemplating leaving Japan. The strength and significance of these pathways varied by region. Mental health and practical implications of these findings are discussed in the light of the continuing uncertainties in Japan following the March 2011 events.

    From Harvard to high school, concern related to academic misconduct, specifically cheating and its impact on societal issues, has become a great concern for educational communities. While a significant number of studies on ethical behaviors in practice in other professions such as business have been published, little research exists on registered nurses in practice. Even fewer studies have, for registered nurses, addressed if there is an association between perceived academic misconduct as students and perceived unethical behaviors in the workplace. The purpose of this study was to determine the relationship between perceptions of registered professional nurses' (RNs) current workplace behaviors and the RNs' retrospective perceptions of their academic misconduct as students. A convenience sample of 1 66 RNs enrolled in master's degree programs at four university schools of nursing completed questionnaires regarding their beliefs and behaviors. The outcome of this study was significant. Results revealed a strong relationship between unethical behaviors of the RN in practice and their prior academic misconduct when they were students.

    There has been a substantial rise in 'economic suicides' in the Great Recessions afflicting Europe and North America. We estimate that the Great Recession is associated with at least 10 000 additional economic suicides between 2008 and 2010. A critical question for policy and psychiatric practice is whether these suicide rises are inevitable. Marked cross-national variations in suicides in the recession offer one clue that they are potentially avoidable. Job loss, debt and foreclosure increase risks of suicidal thinking. A range of interventions, from upstream return-to-work programmes through to antidepressant prescriptions may help mitigate suicide risk during economic downturn. Royal College of Psychiatrists.

    2012-01-01

    Health workforce shortages are a major problem in rural areas. Australian medical schools have implemented a number of rural education and training interventions aimed at increasing medical graduates' willingness to work in rural areas. These initiatives include recruiting students from rural backgrounds, delivering training in rural areas, and providing all students with some rural exposure during their medical training. However there is little evidence regarding the impact of rural exposure versus rural origin on workforce outcomes. The aim of this study is to identify and assess factors affecting preference for future rural practice among medical students participating in the Australian Rural Clinical Schools (RCS) Program. Questionnaires were distributed to 166 medical students who had completed their RCS term in 2006; 125 (75%) responded. Medical students were asked about their preferred location and specialty for future practice, their beliefs about rural work and life, and the impact of the RCS experience on their future rural training and practice preferences. Almost half the students (47%; n=58) self-reported a 'rural background'. Significantly, students from rural backgrounds were 10 times more likely to prefer to work in rural areas when compared with other students (ppreferring general practice, 80% (n=24) wished to do so rurally. Eighty-five per cent (n=105) of students agreed that their RCS experience increased their interest in rural training and practice with 62% (n=75) of students indicating a preference for rural internship/basic training after their RCS experience. A substantial percentage (86%; n=108) agreed they would consider rural practice after their RCS experience. This baseline study provides significant evidence to support rural medical recruitment and retention through education and training, with important insights into the factors affecting preference for future rural practice.

    Who has got the competence in Great Britain to decide about criteria to be applied and methods to be taken in the prevention of damage thus ensuring the required safety standards and definine the maximum acceptable risk to be taken due to the operation of industrial and other facilities. The answer is laid down in the legal regulations covering virtually all industrial and technical installations. The author discusses the skeleton regulations of the 'Health and Safety at Work Act 1974', which is to be considered as the basis of British industrial law. Giving numerous examples, the author explains the legal status and administrative practice concerning the wide range of conventional technical facilities. Furthermore, he describes legal status and administrative practice concerning nuclear facilities and aircraft. After discussing methods of environmental pollution control, especially air pollution, the author enters into the regulations governing planning procedures of great relevance in Britain's legal practice, and the administrative procedures, shown by the example of the Windscale Inquiry. Finally, the author describes methods of risk assessment in other fields of law and some possible approaches to use risk analyses in the framework of the legal system. (orig./HSCH) [de

    Lakes Superior, Huron, Michigan, Ontario, and Erie together form North America's Great Lakes, a region that contains 20% of the world's fresh surface water and is home to roughly one quarter of the U.S. population (Figure 1). Supporting a $4 billion sport fishing industry, plus $16 billion annually in boating, 1.5 million U.S. jobs, and $62 billion in annual wages directly, the Great Lakes form the backbone of a regional economy that is vital to the United States as a whole (see http://www.miseagrant.umich.edu/downloads/economy/11-708-Great-Lakes-Jobs.pdf). Yet the grandeur and importance of this freshwater resource are little understood, not only by people in the rest of the country but also by many in the region itself. To help address this lack of knowledge, the Centers for Ocean Sciences Education Excellence (COSEE) Great Lakes, supported by the U.S. National Science Foundation and the National Oceanic and Atmospheric Administration, developed literacy principles for the Great Lakes to serve as a guide for education of students and the public. These “Great Lakes Literacy Principles” represent an understanding of the Great Lakes' influences on society and society's influences on the Great Lakes.

  11. Does Sympathy Motivate Prosocial Behaviour in Great Apes?

    Liebal, Katja; Vaish, Amrisha; Haun, Daniel; Tomasello, Michael

    2014-01-01

    Prosocial behaviours such as helping, comforting, or sharing are central to human social life. Because they emerge early in ontogeny, it has been proposed that humans are prosocial by nature and that from early on empathy and sympathy motivate such behaviours. The emerging question is whether humans share these abilities to feel with and for someone with our closest relatives, the great apes. Although several studies demonstrated that great apes help others, little is known about their underlying motivations. This study addresses this issue and investigates whether four species of great apes (Pongo pygmaeus, Gorilla gorilla, Pan troglodytes, Pan paniscus) help a conspecific more after observing the conspecific being harmed (a human experimenter steals the conspecific’s food) compared to a condition where no harming occurred. Results showed that in regard to the occurrence of prosocial behaviours, only orangutans, but not the African great apes, help others when help is needed, contrasting prior findings on chimpanzees. However, with the exception of one population of orangutans that helped significantly more after a conspecific was harmed than when no harm occurred, prosocial behaviour in great apes was not motivated by concern for others.

    2017-02-01

    Full Text Available The financial crises of 2007-2008, caused wide-spread falling output and unemployment, in the affected countries and also globally. The severity of the recession was such that it was called the “Great Recession”. As a result of an increase in demand from China and India, at the same time, oil prices rose significantly. The empirical results from this study show that oil price changes negatively affected global growth rate in the 1970s but not in the 1990s and 2000s. These results suggest that the Great Recession in 2008 that initiated by the financial crises, was independent of a significant rise in oil prices.

  13. Making Psychotherapy Great Again?

    Plakun, Eric M

    2017-05-01

    Psychotherapy never stopped being as "great" as other treatments. This column explores the evidence base for both psychotherapy and medications, using depression as a specific example. The limitations are comparable for psychotherapy and medication, with much of the evidence based on small degrees of "statistically significant" rather than "clinically meaningful" change. Our field's biomedical emphasis leads to a false assumption that most patients present with single disorders, when comorbidity is the rule rather than the exception. This false assumption contributes to limitations in the evidence base and in our ability to treat patients optimally.

  14. Great Apes and Biodiversity Offset Projects in Africa: The Case for National Offset Strategies

    The development and private sectors are increasingly considering “biodiversity offsets” as a strategy to compensate for their negative impacts on biodiversity, including impacts on great apes and their habitats in Africa. In the absence of national offset policies in sub-Saharan Africa, offset design and implementation are guided by company internal standards, lending bank standards or international best practice principles. We examine four projects in Africa that are seeking to compensate for their negative impacts on great ape populations. Our assessment of these projects reveals that not all apply or implement best practices, and that there is little standardization in the methods used to measure losses and gains in species numbers. Even if they were to follow currently accepted best-practice principles, we find that these actions may still fail to contribute to conservation objectives over the long term. We advocate for an alternative approach in which biodiversity offset and compensation projects are designed and implemented as part of a National Offset Strategy that (1) takes into account the cumulative impacts of development in individual countries, (2) identifies priority offset sites, (3) promotes aggregated offsets, and (4) integrates biodiversity offset and compensation projects with national biodiversity conservation objectives. We also propose supplementary principles necessary for biodiversity offsets to contribute to great ape conservation in Africa. Caution should still be exercised, however, with regard to offsets until further field-based evidence of their effectiveness is available. PMID:25372894

    The National Radiological Protection Board of the UK has just completed a national survey to determine the genetically significant dose (GSD) to the population of Great Britain from diagnostic radiology. A statistically selected sample of about 80 hospitals spread throughout England, Scotland and Wales has supplied information on the numbers of patients examined in their X-ray departments during a week in June 1977, together with details of age, sex and examination technique. This sample is sufficient to make a reliable estimate of the total diagnostic work-load in all National Health Service Hospitals throughout Great Britain for a year. Gonadal doses from 16 examination types that are likely to be the main contributors to the GSD have been measured on nearly 5000 patients at 20 hospitals throug'out the country using specially developed thermoluminescent dosemeters. These gonadal doses are combined with the examination frequency figures and current values for child expectancy derived from data supplied by tthe registrar general, to estimate the GSD. Those changes in practice which have occurred since the late 1950's which may have influenced the new value for the GSD are discussed, as well as the progress that has been made in estimating population somatic doses from diagnostic radiology using clinical measurements that are currently underway.

    2011-04-01

    Revolutionary changes have taken place to nurses' roles and clinical responsibilities over the past decade, leading to new ways of working and higher levels of nursing practice. However, despite the development of nurse-led clinics and services within oncology there has been little formal evaluation. A survey of 103 UK oncology specialist nurses was undertaken to explore their scope of practice, with emphasis on nurse-led services. The survey highlighted significant developments within nurses' roles and nurse-led services, although there was a distinct lack of clarity between nurses' titles and their roles/responsibilities. Most nurses had extended their role. However there were significant differences in the nature of clinical practice, such as clinical examination and nurse prescribing. Overall, new roles were greatly valued by the multidisciplinary team, reducing waiting times and providing benefits for patients. However other nurses felt frustrated by deficiencies in infrastructure and support, which often overshadowed potential benefits. There is a great diversity in oncology specialist nurses' roles; however lack of clarity in titles, training, competencies and responsibilities is creating confusion. Role developments and nurse-led clinics have been ad hoc and poorly evaluated. The introduction of a competency framework, national standards and a system of clinical appraisals seems key to providing increased transparency and vital safeguards for both nurses and patients. Without further exploration and evaluation of nurse-led initiatives it is difficult to fully appreciate their impact on patients, staff and service delivery. Copyright © 2010 Elsevier Ltd.

    2013-01-01

    There is increasing demand for the implementation of effects-based monitoring and surveillance (EBMS) approaches in the Great Lakes Basin to complement traditional chemical monitoring. Herein, we describe an ongoing multiagency effort to develop and implement EBMS tools, particularly with regard to monitoring potentially toxic chemicals and assessing Areas of Concern (AOCs), as envisioned by the Great Lakes Restoration Initiative (GLRI). Our strategy includes use of both targeted and open-ended/discovery techniques, as appropriate to the amount of information available, to guide a priori end point and/or assay selection. Specifically, a combination of in vivo and in vitro tools is employed by using both wild and caged fish (in vivo), and a variety of receptor- and cell-based assays (in vitro). We employ a work flow that progressively emphasizes in vitro tools for long-term or high-intensity monitoring because of their greater practicality (e.g., lower cost, labor) and relying on in vivo assays for initial surveillance and verification. Our strategy takes advantage of the strengths of a diversity of tools, balancing the depth, breadth, and specificity of information they provide against their costs, transferability, and practicality. Finally, a series of illustrative scenarios is examined that align EBMS options with management goals to illustrate the adaptability and scaling of EBMS approaches and how they can be used in management decisions.

    Debates around policies regulating e-cigarette use make it important to obtain an overview of current practice, people's attitudes and correlates of policy support. Aims were to assess (i) current practices for e-cigarette use in homes and workplaces; (ii) characteristics associated with allowing e-cigarette use in the home; and (iii) level of, and characteristics associated with, support for extending smoke-free legislation to include e-cigarettes. Online survey in 2016, n = 11 389 adults in Great Britain. Descriptives for all measures; multivariable logistic regressions assessed correlates of allowing e-cigarette use and support for extension of legislation. Most (79%) reporting on workplace policies reported some level of restrictions on e-cigarette use. Small majorities would not allow e-cigarette use in their home (58%) and supported an extension of smoke-free legislation (52%; 21% opposed). Allowing use was less likely and supporting an extension more likely among men, respondents from a higher socio-economic status, ex-smokers, never-smokers, non-users of e-cigarettes and respondents with increased perceived harm of e-cigarettes or nicotine (all P e-cigarette use. Over half of adults would not allow use of e-cigarettes in their home and support prohibiting the use of e-cigarettes in smoke-free places. Adjusting for socio-demographics, more restrictive attitudes are more common among never-smokers, never-users and those with increased perception of relative harms of e-cigarettes or nicotine as cause of smoking-related illness. © The Author 2017.

    2013-01-01

    In this article recession magnitudes in Europe, the USA and Japan during the Great Recession are compared. The strongest recessions (of severe category) occurred in Latvia, Lithuania and Estonia, while recessions in Japan and the USA were significantly weaker. Even the strongest recession (in Latvia) was found smaller in its magnitude than the Great Depression 1929-1933 in the USA. Hence, comparisons of the Great Recession to the Great Depression in the literature are somewhat exaggerated.

    2006-01-01

    We examined the possible effects of heavy metal exposure on the quality and health of adult great tits (Parus major) at four study sites along a pollution gradient near a non-ferrous smelter in Belgium. Tarsus length, wing length, body mass and condition of great tits were compared with respect to study site, age (first-year and older great tits), sex and season (birds caught in winter and during breeding). Tarsus length did not differ significantly among study sites. The wing length of great tits was larger at the study site furthest from the smelter, especially for older great tits. The length of the outermost tail feathers, however, did not differ significantly among study sites. We found no signs of loss of body mass or condition towards the pollution source. The body mass and condition was lowest for female great tits at the site furthest from the smelter, especially during winter. Haematocrit values did not differ significantly among sites. Overall, we found no clear significant effects of heavy metal pollution on morphological measurements and health parameters of great tits. - Heavy metal pollution had no clear effect on condition and health, but this may have been masked by habitat quality differences and gene flow

  7. The Evolving Law of Disputed Relocation: constructing inner-city renewal practices in Shanghai, 1990-2005.

    Science.gov (United States)

    Shih, Mi

    2010-01-01

    The forceful pursuit of inner-city renewal in Shanghai since the early 1990s has to a great extent achieved spatial modernization, but at the same time it has given rise to increasing conflicts over residential relocation. Using law as a prism through which to examine the dialectic relationship between renewal practices and disputed relocation, this article argues that the series of unprecedented enactments in law that have taken place during this period have both paved the way for real estate market expansion and been a significant source of relocation disputes in Shanghai. Rather than viewing law as simply given and determinate, the article traces the regulatory regime's codification of property practices as a means of actively responding to the requirements of the real estate market. Under large-scale renewal practices, residents' legal rights of "return settlement" (huiban) in inner-city areas were largely denied in the early 1990s, before being effectively abolished by the adoption of monetary compensation for displacement in the 2000s. The evolving law on property practices has greatly shaped the process of disputed relocation while simultaneously posing a potential challenge to China's use of law for market-oriented development.

  10. Great apes prefer cooked food.

    Wobber, Victoria; Hare, Brian; Wrangham, Richard

    2008-08-01

    The cooking hypothesis proposes that a diet of cooked food was responsible for diverse morphological and behavioral changes in human evolution. However, it does not predict whether a preference for cooked food evolved before or after the control of fire. This question is important because the greater the preference shown by a raw-food-eating hominid for the properties present in cooked food, the more easily cooking should have been adopted following the control of fire. Here we use great apes to model food preferences by Paleolithic hominids. We conducted preference tests with various plant and animal foods to determine whether great apes prefer food items raw or cooked. We found that several populations of captive apes tended to prefer their food cooked, though with important exceptions. These results suggest that Paleolithic hominids would likewise have spontaneously preferred cooked food to raw, exapting a pre-existing preference for high-quality, easily chewed foods onto these cooked items. The results, therefore, challenge the hypothesis that the control of fire preceded cooking by a significant period.

    More than three years ahead of the "Great American Eclipse" of August 2017, the American Astronomical Society formed the AAS Solar Eclipse Task Force to function as a think tank, coordinating body, and communication gateway to the vast resources available about the 2017 eclipse and solar eclipses more generally. The task force included professional and amateur astronomers, formal and informal educators, and science journalists; many had experienced total solar eclipses before, and others would experience their first totality in August 2017. The AAS task force secured funding from the AAS Council, the National Science Foundation, and NASA. These resources were used mainly for three purposes: (1) to build a website that contains basic information about solar eclipses, safe viewing practices, and eclipse imaging and video, along with resources for educators and the media and a searchable map of eclipse-related events and activities, with links to other authoritative websites with more detailed information; (2) to solicit, receive, evaluate, and fund proposals for mini-grants to support eclipse-related education and public outreach to underrepresented groups both inside and outside the path of totality; and (3) to organize a series of multidisciplinary workshops across the country to prepare communities for the eclipse and to facilitate collaborations between astronomers, meteorologists, school administrators, and transporation and emergency-management professionals. Most importantly, the AAS Solar Eclipse Task Force focused on developing and disseminating appropriate eclipse safety information. The AAS and NASA jointly developed safety messaging that won the endorsement of the American Academies of Opthalmology and Optometry. In the weeks immediately preceding the eclipse, it became clear that the marketplace was being flooded by counterfeit eclipse glasses and solar viewers, leading to a last minute change in our communication strategy. In this talk, we'll review the

    2007-01-01

    Impact significance determination is widely recognized as a vital and critical EIA activity. But impact significance related concepts are poorly understood. And the quality of approaches for impact significance determination in EIA practice remains highly variable. This article seeks to help establish a sound and practical conceptual foundation for formulating and evaluating impact significance determination approaches. It addresses the nature (what is impact significance?), the core characteristics (what are the major properties of significance determination?), the rationale (why are impact significance determinations necessary?), the procedural and substantive objectives (what do impact significance determinations seek to achieve?), and the process for making impact significance judgments (how is impact significance determination conducted?). By identifying fundamental attributes and key distinctions associated with impact significance determinations, a basis is provided for designing and evaluating impact significance determination procedures at both the regulatory and applied levels

    The Great Lakes region, as defined here, includes the Great Lakes and their drainage basins in Minnesota, Wisconsin, Illinois, Indiana, Ohio, Pennsylvania, and New York. The region also includes the portions of Minnesota, Wisconsin, and the 21 northernmost counties of Illinois that lie in the Mississippi River drainage basin, outside the floodplain of the river. The region spans about 9º of latitude and 20º of longitude and lies roughly halfway between the equator and the North Pole in a lowland corridor that extends from the Gulf of Mexico to the Arctic Ocean.The Great Lakes are the most prominent natural feature of the region (Fig. 1). They have a combined surface area of about 245,000 square kilometers and are among the largest, deepest lakes in the world. They are the largest single aggregation of fresh water on the planet (excluding the polar ice caps) and are the only glacial feature on Earth visible from the surface of the moon (The Nature Conservancy 1994a).The Great Lakes moderate the region’s climate, which presently ranges from subarctic in the north to humid continental warm in the south (Fig. 2), reflecting the movement of major weather masses from the north and south (U.S. Department of the Interior 1970; Eichenlaub 1979). The lakes act as heat sinks in summer and heat sources in winter and are major reservoirs that help humidify much of the region. They also create local precipitation belts in areas where air masses are pushed across the lakes by prevailing winds, pick up moisture from the lake surface, and then drop that moisture over land on the other side of the lake. The mean annual frost-free period—a general measure of the growing-season length for plants and some cold-blooded animals—varies from 60 days at higher elevations in the north to 160 days in lakeshore areas in the south. The climate influences the general distribution of wild plants and animals in the region and also influences the activities and distribution of the human

    Full Text Available The study determined the effective teaching practices in handling nonreaders. This seeks to answer the following objectives: describe the adjustments, effective strategies, and scaffolds utilized by teachers in handling nonreaders; differentiate the teachers’ reading adjustments, strategies and scaffolds in teaching nonreaders; analyze the teaching reading efficiency of nonreaders using effective teaching reading strategies; and find significant correlation of nonreaders’ grades and reading teachers’ reading adjustments, strategies and scaffolds. This study utilized mixed methods of research. Case studies of five public schools teachers were selected as primary subjects, who were interviewed in handling nonreaders in the areas of adjustments, strategies, and reading scaffolds. Actual teaching observation was conducted according to the five subjects’ most convenient time. In ascertaining the nonreaders’ academic performance, the students’ grades in English subject was analyzed using T-Test within subject design. Handling nonreaders in order to read and understand better in the lesson is an arduous act, yet; once done with effectiveness and passion, it yielded a great amount of learning success. Effective teaching practices in handling nonreaders comprised the use of teachers’ adjustments, strategies, and scaffolds to establish reading mastery, exposing them to letter sounds, short stories, and the use of follow-up. WH questions enhanced their reading performance significantly. Variations of reading teachers’ nature as: an enabler, a facilitator, a humanist, a behaviorist, and an expert, as regards to their teaching practices, were proven significant to students’ reading effectiveness.

    Transfusion practice might significantly influence patient morbidity and mortality. Between European countries, transfusion practice of red blood cells (RBC) greatly differs. Only sparse data are available on transfusion practice of general internal medicine physicians in Switzerland. In this cross-sectional survey, physicians working in general medicine teaching hospitals in Switzerland were investigated regarding their self-reported transfusion practice in anemic patients without acute bleeding. The definition of anemia, transfusion triggers, knowledge on RBC transfusion, and implementation of guidelines were assessed. 560 physicians of 71 hospitals (64%) responded to the survey. Anemia was defined at very diverging hemoglobin values (by 38% at a hemoglobin Switzerland. Identifying and subsequently correcting this deficit in knowledge translation may have a significant impact on patient care.

  1. Do invasive quagga mussels alter CO2 dynamics in the Laurentian Great Lakes?

    Lin, Peng; Guo, Laodong

    2016-12-01

    The Laurentian Great Lakes have experienced unprecedented ecological and environmental changes, especially after the introduction of invasive quagga mussel (Dreissena rostriformis bugensis). While impacts on ecological functions have been widely recognized, the response of carbon dynamics to invasive species remains largely unknown. We report new CO2 data showing significant increases in pCO2 (up to 800 μatm in Lake Michigan) and CO2 emission fluxes in most of the Great Lakes compared to those prior to or during the early stage of the colonization of invasive quagga mussels. The increased CO2 supersaturation is most prominent in Lakes Huron and Michigan, followed by Lakes Ontario and Erie, but no evident change was observed in Lake Superior. This trend mirrors the infestation extent of invasive quagga mussels in the Great Lakes and is consistent with the decline in primary production and increase in water clarity observed pre- and post-Dreissena introduction, revealing a close linkage between invasive species and carbon dynamics. The Great Lakes have become a significant CO2 source to the atmosphere, emitting >7.7 ± 1.0 Tg-C annually, which is higher than the organic carbon burial rate in global inland-seas and attesting to the significant role of the Laurentian Great Lakes in regional/global CO2 budget and cycling.

    The management of radioactive waste and its ultimate dispoal have been a significant problem for the nuclear industry. A lot of resources have been devoted to developing management and dispoal systems. As well as being one of the major technical problems, it has been a very significant public relations issue. Public concern about risks associated with disposal of radioactive waste has been on a global scle. It has focused on local issues in some countries, but generl attitudes have been common worldwide. Great differences exist between countries in the scale and aspects of nuclear technoloy in use. In particular the presence or absence of a nuclear power programme, and to a lesser extent of any nuclear reactors, greatly influence the magnitude of the waste disposal problem. Nevertheless, public perceptions of the problem are to some degree independent of these differences. What radioactive wastes are there in New Zealand? Is there a hazard to the New Zealand public or the New Zealand environment from current radioactive waste disposal practices? What policies are in place to control these practices? This report seeks to provide some information on these questions. It also brings together in one document the waste disposal policies followed by the National Radiation Laboratory for different uses of radioactive mateials. Except for some small quantities which are exempt from most controls, radioactive material can be used in New Zealand only under the control of a person holding a licence under the Radiation Protection Act 1965. All requirements of the Radiation Protection Regulations 1982 must also be observed. More detailed safety advice and further mandatory requirements are contained in codes of safe practice. Compliance with one of these is a condition on most licencees. These provisions are administered by the National Radiation Laboratory (NRL) of the Ministry of Health.

    Family Physician (FP) trainees are expected to be provided with high quality training in well organized practice settings. This study examines differences between FP trainers and non-trainers and their practices to see whether there are differences in trainers and non-trainers and in how their practices are organized and their services are delivered. 203 practices (88 non-training and 115 training) with 512 FPs (335 non-trainers and 177 trainers) were assessed using the "Visit Instrument Practice organization (VIP)" on 369 items (142 FP-level; 227 Practice level). Analyses (ANOVA, ANCOVA) were conducted for each level by calculating differences between FP trainees and non-trainees and their host practices. Trainers scored higher on all but one of the items, and significantly higher on 47 items, of which 13 remained significant after correcting for covariates. Training practices scored higher on all items and significantly higher on 61 items, of which 23 remained significant after correcting for covariates. Trainers (and training practices) provided more diagnostic and therapeutic services, made better use of team skills and scored higher on practice organization, chronic care services and quality management than non-training practices. Trainers reported more job satisfaction and commitment and less job stress than non-trainers. There are positive differences between FP trainers and non-trainers in both the level and the quality of services provided by their host practices. Training institutions can use this information to promote the advantages of becoming a FP trainer and training practice as well as to improve the quality of training settings for FPs.

  8. Building Indigenous Community Resilience in the Great Plains

    Gough, B.

    2014-12-01

    Indigenous community resilience is rooted in the seasoned lifeways, developed over generations, incorporated into systems of knowledge, and realized in artifacts of infrastructure through keen observations of the truth and consequences of their interactions with the environment found in place over time. Their value lies, not in their nature as artifacts, but in the underlying patterns and processes of culture: how previous adaptations were derived and evolved, and how the principles and processes of detailed observation may inform future adaptations. This presentation examines how such holistic community approaches, reflected in design and practice, can be applied to contemporary issues of energy and housing in a rapidly changing climate. The Indigenous Peoples of the Great Plains seek to utilize the latest scientific climate modeling to support the development of large, utility scale distributed renewable energy projects and to re-invigorate an indigenous housing concept of straw bale construction, originating in this region. In the energy context, we explore the potential for the development of an intertribal wind energy dynamo on the Great Plains, utilizing elements of existing federal policies for Indian energy development and existing federal infrastructure initially created to serve hydropower resources, which may be significantly altered under current and prospective drought scenarios. For housing, we consider the opportunity to address the built environment in Indian Country, where Tribes have greater control as it consists largely of residences needed for their growing populations. Straw bale construction allows for greater use of local natural and renewable materials in a strategy for preparedness for the weather extremes and insurance perils already common to the region, provides solutions to chronic unemployment and increasing energy costs, while offering greater affordable comfort in both low and high temperature extremes.

    Full Text Available Surveys on breast-feeding practices have revealed a satisfactory situation in many parts of the country. However, adequacy in terms of quality and quantity of breast milk has not been studied much. Reports available indicate secretion of adequate amount of milk by the mother. This however should not be equated with adequacy of nutrients to this growing child. Concentrations of vitamins are low. The immunologica factors, proteins, minerals and calorie content are in the normal ranges observed in milk samples obtained from well-nourished mother. Breast-feeding should be recommended for as long as possible with adequate supplements. This will have a salubrious effect on the infant and help mothers in spacing births of children. Growth of infants fed soley on breast milk is satisfactory during the first 4 to 5 months. Proper time and type of supplements to be recommended for the community in general need to be studied. Effect of work outside the house on the mother and child, if any, has not received the attention it deserves. High priority has to be a corded to this study, in the present context of dynamic change occurring in the country in relation to the working status of women. Indian is considered a developing country and Indians are conservative by nature. Attitude of the community to infant feeding has not change much except in the educated urban elite and a small section of the poor who consider practice among the former as ideal. The concern and anxiety expressed with regard to breast-feeding by health personnel in foreign countries have not evoked the same response in our country. Reasons are many but if any single reason is to be assigned, it is the popularity of breast-feeding in a vast majority of our mothers. This article will highlight the findings of selected surveys on breast-feeding in the context of our present infant and pre-school feeding practices and refers to the quality and quantity of breast milk briefly.

    2009-01-01

    We examined thiaminase activity in dreissenid mussels collected at different depths and seasons, and from various locations in Lakes Michigan, Ontario, and Huron. Here we present evidence that two dreissenid mussel species (Dreissena bugensis and D. polymorpha) contain thiaminase activity that is 5-100 fold greater than observed in Great Lakes fishes. Thiaminase activity in zebra mussels ranged from 10,600 to 47,900??pmol g- 1??min- 1 and activities in quagga mussels ranged from 19,500 to 223,800??pmol g- 1??min- 1. Activity in the mussels was greatest in spring, less in summer, and least in fall. Additionally, we observed greater thiaminase activity in dreissenid mussels collected at shallow depths compared to mussels collected at deeper depths. Dreissenids constitute a significant and previously unknown pool of thiaminase in the Great Lakes food web compared to other known sources of this thiamine (vitamin B1)-degrading enzyme. Thiaminase in forage fish of the Great Lakes has been causally linked to thiamine deficiency in salmonines. We currently do not know whether linkages exist between thiaminase activities observed in dreissenids and the thiaminase activities in higher trophic levels of the Great Lakes food web. However, the extreme thiaminase activities observed in dreissenids from the Great Lakes may represent a serious unanticipated negative effect of these exotic species on Great Lakes ecosystems.

  16. Precipitation Dynamical Downscaling Over the Great Plains

    2018-02-01

    Detailed, regional climate projections, particularly for precipitation, are critical for many applications. Accurate precipitation downscaling in the United States Great Plains remains a great challenge for most Regional Climate Models, particularly for warm months. Most previous dynamic downscaling simulations significantly underestimate warm-season precipitation in the region. This study aims to achieve a better precipitation downscaling in the Great Plains with the Weather Research and Forecast (WRF) model. To this end, WRF simulations with different physics schemes and nudging strategies are first conducted for a representative warm season. Results show that different cumulus schemes lead to more pronounced difference in simulated precipitation than other tested physics schemes. Simply choosing different physics schemes is not enough to alleviate the dry bias over the southern Great Plains, which is related to an anticyclonic circulation anomaly over the central and western parts of continental U.S. in the simulations. Spectral nudging emerges as an effective solution for alleviating the precipitation bias. Spectral nudging ensures that large and synoptic-scale circulations are faithfully reproduced while still allowing WRF to develop small-scale dynamics, thus effectively suppressing the large-scale circulation anomaly in the downscaling. As a result, a better precipitation downscaling is achieved. With the carefully validated configurations, WRF downscaling is conducted for 1980-2015. The downscaling captures well the spatial distribution of monthly climatology precipitation and the monthly/yearly variability, showing improvement over at least two previously published precipitation downscaling studies. With the improved precipitation downscaling, a better hydrological simulation over the trans-state Oologah watershed is also achieved.

    2016-03-01

    The practice parameters for allergy and immunology (A/I) are a valuable tool guiding practitioners' clinical practice. The A/I practice parameters have evolved over time in the context of evidence-based medicine milestones. To identify evolutionary trends in the character, scope, and evidence underlying recommendations in the A/I practice parameters. Practice parameters that have guided A/I from 1995 through 2014 were analyzed. Statements and recommendations with strength of recommendation categories A and B were considered to have a basis in evidence from controlled trials. Forty-three publications and updates covering 25 unique topics were identified. There was great variability in the number of recommendations made and the proportion of statements with controlled trial evidence. The mean number of recommendations made per practice parameter has decreased significantly, from 95.8 to a mean of 38.3. There also is a trend toward an increased proportion of recommendations based on controlled trial evidence in practice parameters with fewer recommendations, with a mean of 30.7% in practice parameters with at least 100 recommendations based on controlled trial evidence compared with 48.3% in practice parameters with 30 to 100 recommendations and 51.0% in those with fewer than 30 recommendations. The A/I practice parameters have evolved significantly over time. Encouragingly, greater controlled trial evidence is associated with updated practice parameters and a recent trend of more narrowly focused topics. These findings should only bolster and inspire confidence in the utility of the A/I practice parameters in assisting practitioners to navigate through the uncertainty that is intrinsic to medicine in making informed decisions with patients.

    2014-12-01

    The Vietnam Low-Carbon Rice Project (VLCRP) seeks to significantly reduce GHG emissions from rice cultivation, an activity responsible for more than 30% of Vietnam's overall GHG emissions, while improving livelihoods for the rice farmer community by decreasing costs and enhancing yield as well as providing supplemental farmer income through the sale of carbon credits. The Mekong Delta makes up 12% of Vietnam's land area, but produces more than 50% of the country's rice, including more than 90% of the rice for export. Rice cultivation is the main source of income for 80% of farmers in the Mekong Delta. VLCRP was launched in late 2012 in the Mekong Delta in two major rice production provinces, Kien Giang and An Giang. To date, VLCRP has completed 11 crop seasons (in Kien Giang and An Giang combined), training over 400 farmer households in applying VLCRP's package of practices (known as 1 Must - 6 Reductions) and building technical capacity to its key stakeholders and rice farmer community leaders. By adopting the 1 Must- 6 Reductions practices (including reduced seeding density, reduced fertilizer and pesticide application, and alternative wetting and drying water management), rice farmers reduce their input costs while maintaining or improving yields, and decreasing greenhouse gas emissions. The VLCRP package of practices also deliver other environmental and social co-benefits, such as reduced water pollution, improved habitat for fishery resources and reduced health risks for farmers through the reduction of agri-chemicals. VLCRP farmers use significantly less inputs (50% reduction in seed, 30% reduction in fertilizer, 40-50% reduction in water) while improving yields 5-10%, leading to an increase in profit from 10% to as high as 60% per hectare. Preliminary results indicate that the 1 Must- 6 Reductions practices have led to approximately 40-65% reductions in greenhouse gas emissions, equivalent to 4 tons of CO2e/ha/yr in An Giang and 35 tons of CO2e/ha/yr in Kien

  2. Great Lakes waters: radiation dose commitments, potential health effects, and cost-benefit considerations

    1977-07-01

    In 1972, a Great Lakes Water Quality Agreement was signed by the United States and Canadian Governments. It was stipulated that the operation and effectiveness of the agreement were to be reviewed comprehensively in 1977. Aspects of the agreement concern nondegradation of Great Lakes waters and maintenance of levels of radioactivity or other potential pollutants at levels considered as low as practicable. A refined radioactivity objective of one millirem is proposed in the Water Quality Agreement. The implications of adoption of this objective are not known fully. The Division of Environmental Impact Studies was commissioned by ERDA's Division of Technology Overview to summarize the information available on the current levels of radioactivity in Great Lakes waters, compute radiation-dose commitment (integrated dose over 50 years after consumption of 2.2 liters of water of one year), and to comment on the feasibility and cost-benefit considerations associated with the refined one-millirem objective. Current levels of radioactivity in the waters of Lakes Michigan, Ontario, Erie, and Huron result in dose commitments in excess of 1 mrem for whole body and 6 mrem for bone. Future projections of isotope concentrations in Great lakes water indicate similar dose commitments for drinking water in the year 2050. Reduction of the levels of radioactivity in Great Lakes waters is not feasible, but cost-benefit considerations support removal of 226 Ra and 90 Sr through interceptive technology before water consumption. Adoption of the one-millirem objective is not propitious

    Full Text Available Alternative ways to control caterpillar pests and reduce the use of pesticides in apple orchards are in the interest of the environment, farmers and the public. Great tits have already been shown to reduce damage under high caterpillar density when breeding in nest boxes in an experimental apple orchard. We tested whether this reduction also occurs under practical conditions of Integrated Pest Management (IPM, as well as Organic Farming (OF, by setting up an area with nest boxes while leaving a comparable area as a control within 12 commercial orchards. We showed that in IPM orchards, but not in OF orchards, in the areas with breeding great tits, apples had 50% of the caterpillar damage of the control areas. Offering nest boxes to attract insectivorous passerines in orchards can thus lead to more limited pesticide use, thereby adding to the natural biological diversity in an agricultural landscape, while also being economically profitable to the fruit growers.

    Cook, Douglas; Julias, Margaret; Nauman, Eric

    2014-04-11

    Biological systems are characterized by high levels of variability, which can affect the results of biomechanical analyses. As a review of this topic, we first surveyed levels of variation in materials relevant to biomechanics, and compared these values to standard engineered materials. As expected, we found significantly higher levels of variation in biological materials. A meta-analysis was then performed based on thorough reviews of 60 research studies from the field of biomechanics to assess the methods and manner in which biological variation is currently handled in our field. The results of our meta-analysis revealed interesting trends in modeling practices, and suggest a need for more biomechanical studies that fully incorporate biological variation in biomechanical models and analyses. Finally, we provide some case study example of how biological variability may provide valuable insights or lead to surprising results. The purpose of this study is to promote the advancement of biomechanics research by encouraging broader treatment of biological variability in biomechanical modeling. Copyright © 2014 Elsevier Ltd.

    Birdwell, Kevin R. [Oak Ridge National Lab. (ORNL), Oak Ridge, TN (United States)

    2011-05-01

    This research was designed to provide an understanding of physical wind mechanisms within the complex terrain of the Great Valley of Eastern Tennessee to assess the impacts of regional air flow with regard to synoptic and mesoscale weather changes, wind direction shifts, and air quality. Meteorological data from 2008 2009 were analyzed from 13 meteorological sites along with associated upper level data. Up to 15 ancillary sites were used for reference. Two-step complete linkage and K-means cluster analyses, synoptic weather studies, and ambient meteorological comparisons were performed to generate hourly wind classifications. These wind regimes revealed seasonal variations of underlying physical wind mechanisms (forced channeled, vertically coupled, pressure-driven, and thermally-driven winds). Synoptic and ambient meteorological analysis (mixing depth, pressure gradient, pressure gradient ratio, atmospheric and surface stability) suggested up to 93% accuracy for the clustered results. Probabilistic prediction schemes of wind flow and wind class change were developed through characterization of flow change data and wind class succession. Data analysis revealed that wind flow in the Great Valley was dominated by forced channeled winds (45 67%) and vertically coupled flow (22 38%). Down-valley pressure-driven and thermally-driven winds also played significant roles (0 17% and 2 20%, respectively), usually accompanied by convergent wind patterns (15 20%) and large wind direction shifts, especially in the Central/Upper Great Valley. The behavior of most wind regimes was associated with detectable pressure differences between the Lower and Upper Great Valley. Mixing depth and synoptic pressure gradients were significant contributors to wind pattern behavior. Up to 15 wind classes and 10 sub-classes were identified in the Central Great Valley with 67 joined classes for the Great Valley at-large. Two-thirds of Great Valley at-large flow was defined by 12 classes. Winds

    Full Text Available The rules of monasticism were collected and published in a single work entitled Asketikon by Saint Basil the Great. It is arranged in the form of questions and answers to create one coherent work. It has two different publications.The first publication named The Small Asketikon dates to 370-370. It is the fruit of the Saint’s work among Pontic communities and consists of 203 questions and answers. The orignial Greek manuscript has not survived and it is available only in two translations: the Latin Rufin and fragments in Syrian language. The second publication named The Great Asketikon appeard in about 377 and presents the most mature step of cenobitic monasticismin Basil’s elaboration. The Great Asketikon was created by adding new questions to The Small Asketikon and consists of two parts called the The Longer Rules and The Shorter Rules. The Longer Rules are primarily a set of questions and answers. It includes a wide range of rules and norms of the overall life in community. It refers to the fundamental rules of spirituality, such as love, sacrifice, obedience and rudimental problems connected withcommunity organization, cenobitic monasticism and the role of the superior, work and prayer. The second part of The Great Asketikon consists of shorter rules. Two publications are known: the first one originated in Pont andincludes 286 questions and answers and second arose in Cezarei and includes 318 questions and answers. In this work, the Hierarch explains in detail issues regarding community life and solves difficult problems connected with conscience. He writes about behavior towards brothers and explains the significance of weaknesses and virtues.

    Monoclonal gammopathy of undetermined significance and smoldering multiple myeloma are precursor conditions of symptomatic multiple myeloma (MM). Diagnostic principles are aimed at excluding MM requiring therapy, other conditions associated with paraproteins that may require different management, and risk stratifying patients for the purposes of tailored follow-up and investigation. The International Myeloma Working Group have recently published a revised definition of MM, which singles out a small group of patients with smoldering multiple myeloma who are at very high risk of progression and organ damage; such patients are now included under the definition of MM and recommended to start anti-myeloma treatment. Furthermore, the recently published National Institute of Health and Care Excellence guideline recommends cross-sectional imaging techniques in place of skeletal survey. These recent recommendations are discussed, and practical guidance for investigation and management are presented. Copyright © 2016 John Wiley & Sons, Ltd.

    Pollen and sediment analyses of two cores from coastal freshwater swamps at northern Kaitoke (Kaitoke Swamp and Police Station Swamp), Great Barrier Island, show that c. 7300 calibrated yr BP Kaitoke Swamp was an estuary with tidal flats. Avicennia, now absent from the swamp area, was present in the estuary. By c. 4500 yr BP fresh water conditions had developed at the Kaitoke Swamp site as marine influences decreased. Around the same time, fresh water swamp conditions commenced at the Police Station Swamp site on the surface of a low lying area of a Late Pleistocene dune. A sandy layer at Kaitoke may represent rapid infilling followed by a dry soil surface until c. 1000 yr BP. Conifer-hardwood forest on the hills surrounding the sites c. 7300-c. 1800 yr BP was dominated by Dacrydium and Metrosideros. During this period, environmental conditions were relatively stable, with little change in forest composition. Between 1800 yr and 800 yr BP Kaitoke Swamp was reflooded, and the Police Station Swamp extended as a shallow lake over the nearby dune flat. These new shallow swamps were invaded by swamp forest (mainly Dacrycaprus with some Laurelia). The presence of charcoal and Pteridium spores above the Kaharoa Tephra suggests that major Polynesian deforestation at northern Kaitoke began c. 600 calibrated yr BP.

    Okamoto, Carol Midori

    2006-04-01

    This study explored how individuals (biomedical scientists, Great Ape Project activists, lay adults, undergraduate biology and environmental studies students, and Grade 12 and 9 biology students) morally judge and reason about using great apes in biomedical and language research. How these groups perceived great apes' mental capacities (e.g., pain, logical thinking) and how these perceptions related to their judgments were investigated through two scenarios. In addition, the kinds of informational statements (e.g., biology, economics) that may affect individuals' scenario judgments were investigated. A negative correlation was found between mental attributions and scenario judgments while no clear pattern occurred for the informational statements. For the biomedical scenario, all groups significantly differed in mean judgment ratings except for the biomedical scientists, GAP activists and Grade 9 students. For the language scenario, all groups differed except for the GAP activists, and undergraduate environmental studies and Grade 9 students. An in-depth qualitative analysis showed that although the biomedical scientists, GAP activists and Grade 9 students had similar judgments, they produced different mean percentages of justifications under four moral frameworks (virtue, utilitarianism, deontology, and welfare). The GAP activists used more virtue reasoning while the biomedical scientists and Grade 9 students used more utilitarian and welfare reasoning, respectively. The results are discussed in terms of developing environmental/humane education curricula.

  14. Managing authenticity: the paradox of great leadership.

    Science.gov (United States)

    Goffee, Rob; Jones, Gareth

    2005-12-01

    Leaders and followers both associate authenticity with sincerity, honesty, and integrity. It's the real thing--the attribute that uniquely defines great managers. But while the expression of a genuine self is necessary for great leadership, the concept of authenticity is often misunderstood, not least by leaders themselves. They often assume that authenticity is an innate quality--that a person is either genuine or not. In fact, the authors say, authenticity is largely defined by what other people see in you and, as such, can to a great extent be controlled by you. In this article, the authors explore the qualities of authentic leadership. To illustrate their points, they recount the experiences of some of the authentic leaders they have known and studied, including the BBC's Greg Dyke, Nestlé's Peter Brabeck-Letmathe, and Marks & Spencer's Jean Tomlin. Establishing your authenticity as a leader is a two-part challenge. You have to consistently match your words and deeds; otherwise, followers will never accept you as authentic. But it is not enough just to practice what you preach. To get people to follow you, you also have to get them to relate to you. This means presenting different faces to different audiences--a requirement that many people find hard to square with authenticity. But authenticity is not the product of manipulation. It accurately reflects aspects of the leader's inner self, so it can't be an act. Authentic leaders seem to know which personality traits they should reveal to whom, and when. Highly attuned to their environments, authentic leaders rely on an intuition born of formative, sometimes harsh experiences to understand the expectations and concerns of the people they seek to influence. They retain their distinctiveness as individuals, yet they know how to win acceptance in strong corporate and social cultures and how to use elements of those cultures as a basis for radical change.

  16. Dental education and evidence-based educational best practices: bridging the great divide.

    Science.gov (United States)

    Masella, Richard S; Thompson, Thomas J

    2004-12-01

    Research about educational best practices is negatively perceived by many dental faculty. Separation between teaching and learning strategies commonly employed in dental education and evidence-based educational techniques is real and caused by a variety of factors: the often incomprehensible jargon of educational specialists; traditional academic dominance of research, publication, and grantsmanship in faculty promotions; institutional undervaluing of teaching and the educational process; and departmentalization of dental school governance with resultant narrowness of academic vision. Clinician-dentists hired as dental school faculty may model teaching activities on decades-old personal experiences, ignoring recent educational evidence and the academic culture. Dentistry's twin internal weaknesses--factionalism and parochialism--contribute to academic resistance to change and unwillingness to share power. Dental accreditation is a powerful impetus toward inclusion of best teaching and learning evidence in dental education. This article will describe how the gap between traditional educational strategies and research-based practices can be reduced by several approaches including dental schools' promotion of learning cultures that encourage and reward faculty who earn advanced degrees in education, regular evaluation of teaching by peers and educational consultants with inclusion of the results of these evaluations in promotion and tenure committee deliberations, creating tangible reward systems to recognize and encourage teaching excellence, and basing faculty development programs on adult learning principles. Leadership development should be part of faculty enrichment, as effective administration is essential to dental school mission fulfillment. Finally, faculty who investigate the effectiveness of educational techniques need to make their research more available by publishing it, more understandable by reducing educational jargon, and more relevant to the day

    Full Text Available Varicoceles are the most common correctable etiology of male factor infertility. However, the detection and management of varicoceles have not been standardized. This has led to decades of debate regarding the effect of varicocele on male infertility and subsequently whether repair leads to an improved fertility status. The current body of evidence investigating the role of varicocele and varicocelectomy is weak and conflicting. The stance taken by the AUA and ASRM suggests that there is insufficient outcomes data to support evidenced-based guidelines, citing evidence used to provide current recommendations are generally of a low quality level. On the other hand, the EAU Guidelines give a level 1a of evidence for management of varicoceles that are clinically palpable, associated with subnormal semen analyses and having otherwise unexplained fertility. Besides aiding with clinical varicocele detection and management, clinical practice opinion statements and guidelines aim to direct and strengthen the infrastructure of future studies. We review the current status of opinion statements and guidelines in varicocele and management detection with focus on their application in practice.

  4. The great intimidators.

    Kramer, Roderick M

    2006-02-01

    After Disney's Michael Eisner, Miramax's Harvey Weinstein, and Hewlett-Packard's Carly Fiorina fell from their heights of power, the business media quickly proclaimed thatthe reign of abrasive, intimidating leaders was over. However, it's premature to proclaim their extinction. Many great intimidators have done fine for a long time and continue to thrive. Their modus operandi runs counter to a lot of preconceptions about what it takes to be a good leader. They're rough, loud, and in your face. Their tactics include invading others' personal space, staging tantrums, keeping people guessing, and possessing an indisputable command of facts. But make no mistake--great intimidators are not your typical bullies. They're driven by vision, not by sheer ego or malice. Beneath their tough exteriors and sharp edges are some genuine, deep insights into human motivation and organizational behavior. Indeed, these leaders possess political intelligence, which can make the difference between paralysis and successful--if sometimes wrenching--organizational change. Like socially intelligent leaders, politically intelligent leaders are adept at sizing up others, but they notice different things. Those with social intelligence assess people's strengths and figure out how to leverage them; those with political intelligence exploit people's weaknesses and insecurities. Despite all the obvious drawbacks of working under them, great intimidators often attract the best and brightest. And their appeal goes beyond their ability to inspire high performance. Many accomplished professionals who gravitate toward these leaders want to cultivate a little "inner intimidator" of their own. In the author's research, quite a few individuals reported having positive relationships with intimidating leaders. In fact, some described these relationships as profoundly educational and even transformational. So before we throw out all the great intimidators, the author argues, we should stop to consider what

    2001-05-01

    The displacement of important native species in the Great Lakes is a result of an invasion by a succession of non indigenous aquatic species. These invasion also resulted in interference with the proper human water uses and cost billions of dollars. The problem was considered serious enough that the International Joint Commission asked the Great Lakes Water Quality Board in 1999 to review the regulations in place and make recommendations, if necessary, for the implementation of additional measures that could be considered to keep control over the introduction of alien invasive species. Escapes from aquaria, aquaculture, research and educational facilities, canal and diversion water flows, and release of live bait are all sources of this invasion. The effectiveness of alternative technologies to control the invasion was to be examined by the Board. Other efforts taking place to address the situation in the basin are being complemented by the publication of this report. It is considered that the most important source of alien invasive species (AIS) to the Great Lakes is the discharge of ballast water from shipping vessels coming from outside the United States and Canada. A major concern is the role played by vessels reporting no ballast on board (NOBOB) upon entering the basin. A number of recommendations were made concerning: (1) implementation and enforcement of the ballast water discharge standards agreed upon by both countries, (2) the evaluation of the effectiveness of alternative technologies to achieve ballast water discharge standards over the long term, combined with the use of chemical treatment while the evaluation is being performed, (3) the implementation of optimal management practices to control sediments in shipping vessels, (4) modifications to the design of shipping vessels, and (5) the monitoring and contingency plans in the event of a repeat scenario in the future.

    Full Text Available Abstract Background Significant event analysis (SEA is promoted as a team-based approach to enhancing patient safety through reflective learning. Evidence of SEA participation is required for appraisal and contractual purposes in UK general practice. A voluntary educational model in the west of Scotland enables general practitioners (GPs and doctors-in-training to submit SEA reports for feedback from trained peers. We reviewed reports to identify the range of safety issues analysed, learning needs raised and actions taken by GP teams. Method Content analysis of SEA reports submitted in an 18 month period between 2005 and 2007. Results 191 SEA reports were reviewed. 48 described patient harm (25.1%. A further 109 reports (57.1% outlined circumstances that had the potential to cause patient harm. Individual 'error' was cited as the most common reason for event occurrence (32.5%. Learning opportunities were identified in 182 reports (95.3% but were often non-specific professional issues not shared with the wider practice team. 154 SEA reports (80.1% described actions taken to improve practice systems or professional behaviour. However, non-medical staff were less likely to be involved in the changes resulting from event analyses describing patient harm (p Conclusion The study provides some evidence of the potential of SEA to improve healthcare quality and safety. If applied rigorously, GP teams and doctors in training can use the technique to investigate and learn from a wide variety of quality issues including those resulting in patient harm. This leads to reported change but it is unclear if such improvement is sustained.

    To assist the pharmacy clinician engaged in nutrition support in staying current with the most pertinent literature. Several experienced board-certified clinical pharmacists engaged in nutrition support therapy compiled a list of articles published in 2014 and 2015 that they considered to be important to their practice. Only those articles available in print format were considered for potential inclusion. Articles available only in preprint electronic format were not evaluated. The citation list was compiled into a single spreadsheet where the author participants were asked to ascertain whether they considered the paper important to nutrition support pharmacy practice. A culled list of publications was then identified whereby the majority of author participants (at least 5 out of 8) considered the paper to be important. A total of 108 articles were identified; 36 of which were considered to be of high importance. An important guideline article published in early 2016, but not ranked, was also included.

    2017-09-15

    In a study of tick and tick-borne pathogen prevalence, between May and October 2016, 278 veterinary practices in Great Britain examined 1855 cats. Six-hundred and one cats were found to have attached ticks. The most frequently recorded tick species was Ixodes ricinus (57.1%), followed by Ixodes hexagonus (41.4%) and Ixodes trianguliceps (1.5%). Male cats, 4-6 years of age living in rural areas were most likely to be carrying a tick; hair length and tick treatment history had no significant association with attachment. For cats that were parasitized by ticks in large urban areas, I. hexagonus was the most frequent species recorded. Molecular analysis was possible for 541 individual tick samples, others were too damaged for analysis; Babesia spp., and Borrelia burgdorferi sensu lato were identified in 1.1% (n=6) and 1.8% (n=10) of these, respectively. Babesia spp. included Babesia vulpes sp. nov./Babesia microti-like (n=4) in I. hexagonus and Babesia venatorum (n=2) in I. ricinus. Borrelia burgdorferi s.l. species included Borrelia garinii (n=6) and Borrelia afzelii (n=4). The majority of B. burgorferi s.l. cases were found in I. ricinus, with B. afzelii in one I. hexagonus nymph. No Borrelia or Babesia spp. were present in I. trianguliceps. To determine a true prevalence for ticks on cats, practices that only submitted questionnaires from cats with ticks and practices that submitted fewer than 5 returns per week were removed; amongst those considered to have adhered strictly to the collection protocol, feline tick prevalence amongst cats that had access to the outdoors was 6.6%. These results show that ticks can be found on cats throughout Great Britain, which harbour a range of species of Babesia and B. burgdorferi s.l. and that cats, particularly in green spaces within urban areas, may form an important host for I. hexagonus, a known vector of pathogens.

    2015-07-01

    Full Text Available In eight novels, Ayu Utami has presented critical attacks on doctrines and practices of the major religions in Indonesia. The two books, that describe the spiritual struggle of the Catholic priest Saman (1998–2002, call for a religion that is more active in the political arena, but leaves sexual rules to the individual people. The novel Bilangan Fu (2008 condemns the monopoly of the great religions in favour of local and individual spirituality. This is developed in a series of novels of which two more have already appeared. A third cycle of three more or less autobiographic novels (2003–2013 sketch her personal quest from atheism towards a critical but positive spirituality condemning a clerical and monopolist trend in Catholicism. Utami’s criticism of the great religions is external (more players in the field should be recognised and internal (religious leaders should have more modest claims towards their faithful and leave more space for personal choice.

    Million Hearts is a national initiative to prevent 1 million heart attacks and strokes over 5 years by improving cardiovascular prevention. An important tool in the success of programs like Million Hearts is public ranking on the quality of practices, yet different measures may provide different rankings, so the true quality of practices is difficult to discern. We evaluated the quality of ambulatory cardiology care using performance measure metrics. We compared rankings of practices participating in the National Cardiovascular Data Registry's Practice Innovation and Clinical Excellence Registry using measures from (1) the physician quality reporting system and (2) the American College of Cardiology/American Heart Association/Physician Consortium for Performance Improvement. We compared achievement rates for measures between the 2 frameworks and determined correlations in rankings using Spearman correlation coefficients. From January 1, 2008 to December 31, 2012, there were 1,711,326 patients enrolled from 111 US practices. Among eligible patients, the physician quality reporting system and American College of Cardiology/American Heart Association/Physician Consortium for Performance Improvement measures were achieved in 76.1% versus 77.4% for antiplatelet prescription (P performance and failing to achieve public health goals.

  17. Dynamics of DNA methylation in recent human and great ape evolution.

    Directory of Open Access Journals (Sweden)

    Irene Hernando-Herraez

    Full Text Available DNA methylation is an epigenetic modification involved in regulatory processes such as cell differentiation during development, X-chromosome inactivation, genomic imprinting and susceptibility to complex disease. However, the dynamics of DNA methylation changes between humans and their closest relatives are still poorly understood. We performed a comparative analysis of CpG methylation patterns between 9 humans and 23 primate samples including all species of great apes (chimpanzee, bonobo, gorilla and orangutan using Illumina Methylation450 bead arrays. Our analysis identified ∼800 genes with significantly altered methylation patterns among the great apes, including ∼170 genes with a methylation pattern unique to human. Some of these are known to be involved in developmental and neurological features, suggesting that epigenetic changes have been frequent during recent human and primate evolution. We identified a significant positive relationship between the rate of coding variation and alterations of methylation at the promoter level, indicative of co-occurrence between evolution of protein sequence and gene regulation. In contrast, and supporting the idea that many phenotypic differences between humans and great apes are not due to amino acid differences, our analysis also identified 184 genes that are perfectly conserved at protein level between human and chimpanzee, yet show significant epigenetic differences between these two species. We conclude that epigenetic alterations are an important force during primate evolution and have been under-explored in evolutionary comparative genomics.

    Administration in the social field is examined based on an analysis of its practices, the rationalist myth and its ideological dimensions. In this way, the article discusses the most frequently utilized concepts (administration, management, gerencia, gestión) and their etymologies; the limitations of teaching administration; the complexity of a practice marked by the dimensions of science, art and the social game; and the ideological question underlying the great thought factory that the general theory of administration has been since the start of the 19th century. The article reflects upon the need to construct a theory based in practice contextualized in the global south that goes beyond the classic frames of reference and, above all, to transform administration into a problem to be discussed outside of the knowledge that recognizes it as a technical practice.

    In the long-term biomonitoring of wild populations inhabiting polluted areas, the use of non-destructive biomarkers as markers of condition is very important. We examined the possible effects of metal pollution on the haematological status of adult great tits (Parus major) along a well-established pollution gradient near a non-ferrous smelter in Belgium. We measured blood and feather metal concentrations and assessed the haematological status (amount of red blood cells, haemoglobin concentration, haematocrit, mean corpuscular volume and mean corpuscular haemoglobin) of adult great tits during winter at four study sites. Metal concentrations in blood and feathers indicated that cadmium and lead were the most important metals in the pollution gradient under study. Measurements of haematological parameters revealed that haemoglobin concentration, haematocrit, mean corpuscular volume and mean corpuscular haemoglobin were lower in great tits from the more polluted sites. These parameters were significantly negatively correlated with blood lead concentration. The amount of red blood cells, however, did not significantly differ among study sites. Our results indicate that the haematological status of great tits is negatively affected by metal pollution and may therefore be used as a successful biomarker for monitoring the negative impact of metal exposure in the wild.

  3. Climate variability and Great Plains agriculture

    Rosenberg, N.J.; Katz, L.A.

    1991-01-01

    The ways in which inhabitants of the Great Plains, including Indians, early settlers, and 20th century farmers, have adapted to climate changes on the Great Plains are explored. The climate of the Great Plains, because of its variability and extremes, can be very stressful to plants, animals and people. It is suggested that agriculture and society on the Great Plains have, during the last century, become less vulnerable to the stresses imposed by climate. Opinions as to the sustainability of agriculture on the Great Plains vary substantially. Lockeretz (1981) suggests that large scale, high cost technologies have stressed farmers by creating surpluses and by requiring large investments. Opie (1989) sees irrigation as a climate substitute, however he stresses that the Ogallala aquifer must inevitably become depleted. Deborah and Frank Popper (1987) believe that farming on the Plains is unsustainable, and destruction of shelterbelts, out-migration of the rural population and environmental problems will lead to total collapse. With global warming, water in the Great Plains is expected to become scarcer, and although improvements in irrigation efficiency may slow depletion of the Ogallala aquifer, ultimately the acreage under irrigation must decrease to levels that can be sustained by natural recharge and reliable surface flows. 23 refs., 2 figs

  4. Misinterpretation of the strategic significance of cost driver analysis: evidence from management accounting theory and practice

    Directory of Open Access Journals (Sweden)

    Henry T Palowski

    2011-06-01

    Full Text Available This paper traces the development of cost driver theory in the Strategy literature and reflects on misinterpretations of the strategic significance of the theory in related academic disciplines, notably Management Accounting. Management Accounting has largely been responsible for informing costing practice in a wide range of organizational settings. The paper considers one such application- i.e. the case of the Higher Education Funding Council’s (HEFC costing and pricing initiative for UK universities. The project was completed just under five years ago, although details of implementation are still ongoing, to a degree. The systems in place incorporate most of the theoretical flaws outlined in this paper. Rather than providing cost driver analysis to aid the strategic management process in universities, the system appears to represent little more than a compliance and reporting framework between university central administrations and the funding provider, HEFC.

    1993-09-01

    The practicality of underwater abrasive water jet cutting technology was studied in experiments. A study of abrasives in slurried form showed that optimum polymer concentration can be selected to suit underwater conditions. For the long-distance transport of slurry from the ocean surface to the ocean floor, a direct supply system by hose proved to be practical. This system takes advantage of the insolubility of the slurry in water due to a difference in specific gravity. For cutting thick steel plate at great ocean depths, a simulation with a pressurized container revealed the requirements for actual cutting. Confirmation of remote cutting operations will become the most important technology in field applications. Underwater sound vibration characteristics were found to change significantly in direct response to modifications in cutting conditions. This will be important basic data to develop an effective sensoring method.

    Liver samples from red-tailed hawks (Buteo jamaicensis) and great horned owls (Bubo virginianus) were analyzed for anticoagulant rodenticides. Residues of one or more second generation anticoagulant rodenticides (SGARs) were detected in 81 % of red-tailed hawks and 82 % of great horned owls. The most frequently detected SGAR was brodifacoum, which was detected in 76 % of red-tailed hawks and 73 % of great horned owls. Bromadiolone was detected in 20 % of red-tailed hawks and 27 % of great horned owls. Difenacoum was detected in one great horned owl. No other ARs were detected. There were no significant differences between species in the frequency of detection or concentration of brodifacoum or bromadiolone. There was a marginally significant difference (p = 0.0497) between total SGAR residues in red-tailed hawks (0.117 mg/kg) and great horned owls (0.070 mg/kg). There were no seasonal differences in the frequency of detection or concentration of brodifacoum in red-tailed hawks. The data suggest that SGARs pose a significant risk of poisoning to predatory birds in New Jersey.

    Economic stressors have been retrospectively associated with net population increases in nonspecific psychological distress (PD). However, no sentinels exist to evaluate contemporaneous associations. Aggregate Internet search query surveillance was used to monitor population changes in PD around the United States' Great Recession. Monthly PD query trends were compared with unemployment, underemployment, homes in delinquency and foreclosure, median home value or sale prices, and S&P 500 trends for 2004-2010. Time series analyses, where economic indicators predicted PD one to seven months into the future, were performed in 2011. PD queries surpassed 1,000,000 per month, of which 300,000 may be attributable to the Great Recession. A one percentage point increase in mortgage delinquencies and foreclosures was associated with a 16% (95%CI, 9-24) increase in PD queries one-month, and 11% (95%CI, 3-18) four months later, in reference to a pre-Great Recession mean. Unemployment and underemployment had similar associations half and one-quarter the intensity. "Anxiety disorder", "what is depression", "signs of depression", "depression symptoms", and "symptoms of depression" were the queries exhibiting the strongest associations with mortgage delinquencies and foreclosures, unemployment or underemployment. Housing prices and S&P 500 trends were not associated with PD queries. A non-traditional measure of PD was used. It is unclear if actual clinically significant depression or anxiety increased during the Great Recession. Alternative explanations for strong associations between the Great Recession and PD queries, such as media, were explored and rejected. Because the economy is constantly changing, this work not only provides a snapshot of recent associations between the economy and PD queries but also a framework and toolkit for real-time surveillance going forward. Health resources, clinician screening patterns, and policy debate may be informed by changes in PD query

    Dentists have much invested in their practices. They need to protect their practices from fraud and noncompliance. The author provides practical suggestions for how to significantly reduce the risk of fraud and theft in the practice without disrupting day-to-day operations. By adhering to nonintrusive policy and procedure changes, dental practice owners can reduce inherent risks of fraud and theft, while increasing financial and human resource knowledge regarding their practice. Practice owners with the appropriate policies and procedures benefit from significantly lower risk of loss from fraud and theft. Furthermore, they have a better understanding of their practice's finances and human resources. Copyright © 2015 American Dental Association. Published by Elsevier Inc. All rights reserved.

    Full Text Available The present study investigates the impact of customer relationship management practices on the service quality in the banking sector. CRM practices have been found to greatly influence not only the customer satisfaction and loyalty but also the quality of services provided by organization. The study focuses on three CRM practices of Attitude towards clients, Efficiency of banking services and Knowledge ability and their impact on the service quality. As customers are more aware about the services so they ensure service quality. Employee’s knowledge ability helps customers to gain experience that actually leads towards service quality and efficiency in services provided by the banks also help in service quality. The study used survey design and the sample consisted of 230 respondents. These respondents were customers of different banks in the city of Rawalpindi, Pakistan. The results indicate that knowledge ability of employees and attitude towards clients is having significant influence on service quality. However, CRM practice of Efficiency of banking services was found to be insignificant. The study has managerial implications for the banking industry. The study also provides future directions.

  13. Understanding students' epistemologies: Examining practice and meaning in community contexts

    Science.gov (United States)

    Bang, Megan Elisabeth

    There is a great need to raise the levels of science achievement for those groups of children who have traditionally underperformed. Prior cognitive research with Native people suggests that problems with achievement for Native students may be more complicated then simple problems with knowing or not knowing content knowledge. This dissertation hypothesizes that Native Americans engage in practices and have funds of knowledge that facilitate sophisticated reasoning in the domain of science. However, the knowledge and patterns of reasoning are not elicited, acceptable, or recognized in classroom science, or perhaps are in conflict with classroom science. Furthermore the divergence is not simply in the details of what is known; there is discord at the level of epistemology, in the fundamental ways in which Native people conceptualize knowledge of the natural world. This work proposes a new framework, Micro-practice epistemology, for understanding epistemology. I propose that epistemology should be understood as implicitly and explicitly imbedded in the worldviews, values, beliefs and practices of our everyday lives. Using both qualitative and quantitative methods this work investigates the everyday practices related to nature, the epistemological stances and biological knowledge embedded in those practices in a 3X3 model (age cohort: child, adult, elder X community). The three communities involved in this work include: Chicago urban Indian community, Menominee reservation community, and a rural working poor white community. I find significant differences in all three areas across communities. Native communities tend to participate in practices in which some aspect of nature is fore-grounded while non-Native participants tended to participate in practices in which nature is the back-grounded. These findings are extended to explore the ways in which worldviews and values are connected to practice and knowledge about the natural world. I find significant differences in

    Large earthquakes have been associated with cardiovascular disease (CVD) mortality. In Japan, the 1995 Great Hanshin-Awaji (H-A) Earthquake was an urban-underground-type earthquake, whereas the 2011 Great East Japan (GEJ) Earthquake was an ocean-trench type. In the present study, we examined how these different earthquake types affected CVD mortality. We examined death certificate data from 2008 to 2012 for 131 municipalities in Iwate, Miyagi, and Fukushima prefectures (n=320,348) and from 1992 to 1996 for 220 municipalities in Hyogo, Osaka, and Kyoto prefectures (n=592,670). A Poisson regression model showed significant increases in the monthly numbers of acute myocardial infarction (AMI)-related deaths (incident rate ratio [IRR] GEJ=1.34, P=0.001; IRR of H-A=1.57, Pdeaths (IRR of GEJ=1.42, Pdeaths remained significant only for H-A (IRR=1.13, P=0.029). When analyzing the standardized mortality ratio (SMR) after the earthquakes using the Cochran-Armitage trend test, seismic intensity was significantly associated with AMI mortality for 2 weeks after both the GEJ (P for trend=0.089) and H-A earthquakes (P for trend=0.005). Following the GEJ and H-A earthquakes, there was a sharp increase in CVD mortality. The effect of the disaster was sustained for months after the H-A earthquake, but was diminished after the GEJ Earthquake.

    The five largest magnetic storms that occurred between 1971 and 1986 are studied to determine their solar and interplanetary causes. All of the events are found to be associated with high speed solar wind streams led by collisionless shocks. The high speed streams are clearly related to identifiable solar flares. It is found that (1) it is the extreme values of the southward interplanetary magnetic fields rather than solar wind speeds that are the primary causes of great magnetic storms, (2) shocked and draped sheath fields preceding the driver gas (magnetic cloud) are at least as effective in causing the onset of great magnetic storms (3 of 5 events ) as the strong fields within the driver gas itself, and (3) precursor southward fields ahead of the high speed streams allow the shock compression mechanism (item 2) to be particularly geoeffective

This region faces critical challenges regarding balancing food needs, resource conservation (e.g Ogallala aquifer), environmental concerns, and rural economy development. Developing transformative, multifunctional systems will require equally imaginative and efficient tools to help farmers manage complex agroecosystems in a rapidly changing climate. The Northern Plains long-term agroecosystem research (LTAR) site at Mandan, ND and the Platte River High Plains LTAR (ARS/University of Nebraska-Lincoln) at Lincoln, NE in collaboration with USDA-ARS research units in Brookings, SD and Fargo, ND are collaborating to address the grand challenge of providing and sustaining multiple service provisions from Northern Great Plains agroecosystems. We propose to attain these goals through sustainable intensification based on the adoption of conservation agriculture principles including reduced soil disturbance, livestock integration, and greater complexity and diversity in the cropping system. Here, we summarize new concepts these locations have pioneered in dynamic cropping systems, resource use efficiency, and agricultural management technologies. As part of the LTAR network, we will conduct long-term cross-site research to design and assess new agricultural practices and systems aimed at improving our understanding of decision making processes and outcomes across an array of agricultural systems.

    Spinal cord injury arising during anaesthetic practice is a rare event, but one that carries a significant burden in terms of morbidity and mortality. In this article, we will review the pathophysiology of spinal cord injury. We will then discuss injuries relating to patient position, spinal cord hypoperfusion and neuraxial techniques. The most serious causes of spinal cord injury - vertebral canal haematoma, spinal epidural abscess, meningitis and adhesive arachnoiditis - will be discussed in turn. For each condition, we draw attention to practical, evidence-based measures clinicians can undertake to reduce their incidence, or mitigate their severity. Finally, we will discuss transient neurological symptoms. Some cases of spinal cord injury during anaesthesia can be ascribed to anaesthesia itself, arising as a direct consequence of its conduct. The injury to a spinal nerve root by inaccurate and/or incautious needling during spinal anaesthesia is an obvious example. But in many cases, spinal cord injury during anaesthesia is not caused by, related to, or even associated with, the conduct of the anaesthetic. Surgical factors, whether direct (e.g. spinal nerve root damage due to incorrect pedicle screw placement) or indirect (e.g. cord ischaemia following aortic surgery) are responsible for a significant proportion of spinal cord injuries that occur concurrently with the delivery of regional or general anaesthesia. © 2018 The Association of Anaesthetists of Great Britain and Ireland.

  3. Sources of plutonium to the great Miami River

    Progress is reported in the study of 238 Pu, in the Great Miami River watershed the contribution of various sources to the total 238 Pu transported by the river. Periodic discharges of industrial wastewater from Mound Laboratory from 1973 to 1975 have released approximately 20 mCi of 238 Pu each year to the Great Miami River. Changes in the wastewater treatment system in 1976 have reduced the annual discharge to less than 3 mCi/year. However, despite this sevenfold reduction of plutonium in the wastewater discharge, the annual flux of 238 Pu down the river has remained relatively constant and is approximately 10 times greater than can be accounted for by the reported effluent discharges. Therefore, other sources of the 238 Pu in the Great Miami River exist. A second possible source of plutonium is the resuspension of sediments enriched by earlier waste water releases and deposited in the river. However, since there appear to be few areas where large accumulations of sediment could occur, it seems improbable that resuspension of earlier sediment deposits would continue to be a significant contributor to the annual flux of plutonium. A much more likely source is the continuing erosion of soil from a canal and stream system contaminated with approx. 5 Ci of 238 Pu, 7 which connects directly to the river 6.9 km upstream from Franklin. Results from samples analyzed in 1978 show the average concentration of 238 Pu in suspended sediments from the canal to be approximately 10 3 times greater than suspended sediment concentrations in the river and waste water effluent.Thus the main contributor to the total amount of plutonium transported by the Great Miami River appears to be highly enriched sediment from the canal, which is eroded into the river where it is then diluted by uncontaminated sediments

    In our world of seemingly unlimited computing, numerous analytical approaches to the estimation of stress, strain, and displacement, including analytical, numerical, physical, and analog techniques, have greatly advanced the practice of engineering. Combining theory and experimentation, computer simulation has emerged as a third path for engineering design and performance evaluation. As a result, structural engineers working in the practical world of engineering must apply, and ideally, thrive, on these idealizations of science-based theories.

    Described are what Fukushima Medical University (FMU) faced and how FMU responded at Fukushima Daiichi Power Plant (FDPP) Accident by hydrogen explosions (Mar. 12 and 14, 2011) following the Great Eastern Japan Earthquake (Mar. 11). The Accident accompanying the forced evacuation of resident in the area 20 km afar from FDPP brought about the concern, fear and anger, different from those in the neighboring Miyagi Prefecture; and strong psychosomatic stress; as well as the significant alteration of composition of generation in population and in sickness proportion in the whole Prefecture. Under these circumstances, FMU decided to hold information in common and make a service window single, to give the top leadership with rough-and-ready practice and a flexible policy, which all were the president's responsibility for making staff work relieved and united. For holding information in common, frequent meetings of the whole FMU personnel were held (42 times from Mar. 11 to Nov.) and of managing staff (81 times until Nov.). During the period, FMU took measures to meet with the situation of patient receiving and transporting, measures against rumor, and cooperation with related medical institutions. Medicare support included the acute phase medicare, and planning and practice of healthcare management for >30 years onward in the Prefecture. The author summarizes 9 lessons proposed from the Disaster to be considered hereafter, like the system perfection at an emergency, more education about radiation for the resident and medicare staff, measures for aging of engineers and scientists related to atomic energy, and so on. As well, 6 lessons are summarized for the next generation using old aphorism and recent commentary in media. The people should follow the excellent leader at crisis; but it's the problem whether there is such a leader on site or in administration at the very time. (T.T.)

    The purpose of this study was to investigate and assess the nutritional practices of open-water swimmers, during the preparation period and the competition, as well as their implications on performance and anthropometric parameters according to their age. Twenty-four (n = 24) men open-water swimmers, twelve young (26.3 ± 4.9 years) and twelve older athletes (45.8 ± 9.7 years), participated in this study. Nutritional behavior-energy intake consumption, and anthropometric characteristics were evaluated prior to the Toroneos Gulf crossing (26 km). In addition, nutritional intakes during the race and anthropometrics after the race were also evaluated. Significant differences between the two groups were found for Toroneos Gulf crossing performance, BMI, and all variables of body composition at the preparation period (P nutritional intakes during the preparation period and the competition, and athletes' performance. In summary, this study provides strong evidence about the malnutrition of ultra-endurance swimmers prior and during their competition, with potential dangers for their health and performance as certain deficiencies in both macro- and micronutrient contents are present. © 2017 John Wiley & Sons A/S.

    Acoustic signals play a fundamental role in avian territory defence and mate attraction. Several studies have now shown that spectral properties of bird song differ between urban and rural environments. Previously this has been attributed to competition for acoustic space as a result of low......-frequency noise present in cities. However, the physical structure of urban areas may have a contributory effect. Here we investigate the sound degradation properties of woodland and city environments using both urban and rural great tit song. We show that although urban surroundings caused significantly less...... degradation to both songs, the transmission efficiency of rural song compared to urban song was significantly lower in the city. While differences between the two songs in woodland were generally minimal, some measures of the transmission efficiency of rural song were significantly lower than those of urban...

  9. Commentary. The diseases of Alexander the Great.

    York, George K; Steinberg, David A

    2004-06-01

    The accompanying articles that speculate that Alexander the Great had a traumatic carotid dissection or congenital cervical scoliosis demonstrate the difficulties in retrospective diagnosis as a historical enterprise. The extant primary sources were written centuries after Alexander's death and are ambiguous in their original languages, and even more so in translation. Thus we cannot be certain what illness Alexander actually had. Furthermore, anachronistic diagnosis removes Alexander from the medical context of this time, telling us little of historical significance about him. Such investigations also illustrate the more general limits that the absence of context imposes on the study of ancient history.

    Full Text Available Aims:The aims of this study were to assess the prevalence of self-reported halitosis, oral hygiene practices and related diseases among Libyan students and employees.Methods: Six hundred self-administered structured questionnaires were used to investigate self-perception of halitosis and oral hygiene practices among a group of Libyan volunteers. Chi square test was used to detect significant differences between frequencies and to test correlation between self-perception of halitosis and measures of oral hygiene. Results: Forty three percent of the subjects were males and 57% were females. Forty four percent of the males and 54% of the females revealed self-perception malodour. Malodour was reported with the highest frequency (68% during wake up time. Malodour was perceived by 31.7% of the females and 23.4% of the males during the hand-on-mouth test (p=0.04. Significantly more females (89.9% than males (75.7% practiced brushing (p<0.001. Fifty one percent of the males and 49.6% of females had dental caries. Smoking was significantly (p<0.001 more prevalent among males (17% than among females (1%. Brushing was practiced by 85% of non-smokers and 68% of smokers (p=0.004. About 71% of the subjects who practiced brushing reported malodour during wake up time in comparison to subjects who did not practice brushing (p=0.041. Conclusions: The prevalence of self-perceived malodour among the Libyan volunteers in this study is within the range of other studies. There is a great demand to reduce the incidence of dental caries and periodontal diseases.

  11. From the "metaphysics of the individual" to the critique of society: on the practical significance of Michel Henry's phenomenology of life.

    Science.gov (United States)

    Staudigl, Michael

    This essay explores the practical significance of Michel Henry's "material phenomenology." Commencing with an exposition of his most basic philosophical intuition, i.e., his insight that transcendental affectivity is the primordial mode of revelation of our selfhood, the essay then brings to light how this intuition also establishes our relation to both the world and others. Animated by a radical form of the phenomenological reduction, Henry's material phenomenology brackets the exterior world in a bid to reach the concrete interior transcendental experience at the base of all exteriority. The essay argues that this "counter reduction," designed as a practical orientation to the world, suspends all traditional parameters of onto(theo)logical individuation in order to rethink subjectivity in terms of its transcendental corporeality, i.e., in terms of the invisible display of "affective flesh." The development of this "metaphysics of the individual" anchors his "practical philosophy" as he developed it-under shifting accents-throughout his oeuvre. In particular, the essay brings into focus Henry's reflections on modernity, the industry of mass culture and their "barbaric" movements. The essay briefly puts these cultural and political areas of Henry's of thinking into contact with his late "theological turn," i.e., his Christological account of Life and the (inter)subjective self-realization to which it gives rise.

    Full Text Available Background/Aims: Although the role of capsule endoscopy (CE in Crohn's disease (CD has expanded, CE is not used routinely for diagnosing and evaluating CD in Korea. We aimed to investigate current patterns of practice and evaluate the clinical significance of the use of CE in CD in Korean patients.Methods: Among 651 CE procedures performed for various indications, we retrospectively analyzed the medical records of patients who underwent CE in 57 cases of suspected CD (sCD and 14 cases of established CD (eCD.Results: In the sCD group, CE was most commonly used for the initial diagnosis of CD (54.4%. Capsule retention was found in only 1 patient in the eCD group (1/71, 1.4%. In the sCD group, 28.1% of patients were diagnosed with CD on the basis of CE findings; other diseases diagnosed included tuberculous enteritis (7.0%, non-steroidal anti-inflammatory drug-induced enteropathy (5.3%, and other enteritis (17.5%. Only 11.5% of patients with eCD (14/122 underwent CE. The indication for CE in the 14 patients with eCD was to assess disease extent and activity. The overall diagnostic yield of CE was 59.7%. Therapeutic strategies were changed in 70.2% of patients in the sCD group and 50% of those in the eCD group based on CE findings.Conclusions: In clinical practice, CE was most commonly indicated for the initial diagnosis of CD and was not generally performed in patients with eCD. CE appears to be an effective diagnostic modality for evaluating sCD and is useful for determining therapeutic strategies for patients with sCD and those with eCD.

    2009-01-01

    Over the last decade, a consensus has emerged regarding a set of evidence-based practices for schizophrenia that address symptom management and psychosocial functioning. Yet, surveys suggest that the great majority of the population of individuals with schizophrenia do not receive evidence-based care. In this article, we review the empirical literature on implementation of evidence-based practices for schizophrenia patients. We first examine lessons learned from implementation studies in general medicine. We then summarize the implementation literature specific to schizophrenia, including medication practices, psychosocial interventions, information technology, and state- and federal-level interventions. We conclude with recommendations for future directions. PMID:19491315

    Tomasello, Michael; Call, Josep

    2018-02-21

    We and our colleagues have been doing studies of great ape gestural communication for more than 30 years. Here we attempt to spell out what we have learned. Some aspects of the process have been reliably established by multiple researchers, for example, its intentional structure and its sensitivity to the attentional state of the recipient. Other aspects are more controversial. We argue here that it is a mistake to assimilate great ape gestures to the species-typical displays of other mammals by claiming that they are fixed action patterns, as there are many differences, including the use of attention-getters. It is also a mistake, we argue, to assimilate great ape gestures to human gestures by claiming that they are used referentially and declaratively in a human-like manner, as apes' "pointing" gesture has many limitations and they do not gesture iconically. Great ape gestures constitute a unique form of primate communication with their own unique qualities.

    In the decade after World War II, psychologists, eager to bring the benefits of counseling to larger numbers, convinced hundreds of American colleges and universities to establish counseling centers. Inspired by the educational-vocational counseling center founded by psychologists at the University of Minnesota in 1932, Carl R. Rogers's "client-centered" methods of personal adjustment counseling, and the 400-plus college counseling centers created by the Veterans Administration to provide the educational-vocational counseling benefit promised to returning World War II servicemen under the 1944 GI Bill, these counseling psychologists created a new place to practice where important currents in psychology, higher education, and federal policy converged and where they attempted to integrate educational-vocational counseling with personal adjustment counseling based on techniques from psychotherapy. By the mid-1960s, half of America's colleges and universities had established counseling centers, and more than 90% offered students educational, vocational, and psychological counseling services, a great achievement of the first generation of counseling psychologists.

    2003-09-01

    Against the background of a beginning shortage of psychiatrists, results from interviews with 112 employees of an automotive company with the topic "Great Job" are presented to discuss their relevance to psychiatry. The interviews were analysed by means of a qualitative content analysis. Most employees assigned importance to great pay, constructive collaboration with colleagues, and work appealing to personal interests. Further statements particularly relevant to psychiatry were: successful career, flexible working hours, manageable job, work-life balance, well-founded training, no bureaucracy within the company, and personal status in society. The well-known economic restrictions in health care and the still negative attitude towards psychiatry currently reduce the attraction of psychiatry as a profession. From the viewpoint of personnel management, the attractors of a great job revealed in this study are proposed as important clues for the recruitment of medical students for psychiatry and the development of psychiatric staff.

    Pacific salmon (genus Oncorhynchus) are a valuable resource, both within their native range in the North Pacific rim and in the Great Lakes basin. Understanding their value from a biological and economic perspective in the Great Lakes, however, requires an understanding of changes in the ecosystem and of management actions that have been taken to promote system stability, integrity, and sustainable fisheries. Pacific salmonine introductions to the Great Lakes are comprised mainly of Chinook salmon, coho salmon, and steelhead and have accounted for 421, 177, and 247 million fish, respectively, stocked during 1966-2007. Stocking of Pacific salmonines has been effective in substantially reducing exotic prey fish abundances in several of the Great Lakes (e.g., lakes Michigan, Huron, and Ontario). The goal of our evaluation was to highlight differences in management strategies and perspectives across the basin, and to evaluate policies for Pacific salmonine management in the Great Lakes. Currently, a potential conflict exists between Pacific salmonine management and native fish rehabilitation goals because of the desire to sustain recreational fisheries and to develop self-sustaining populations of stocked Pacific salmonines in the Great Lakes. We provide evidence that suggests Pacific salmonines have not only become naturalized to the food webs of the Great Lakes, but that their populations (specifically Chinook salmon) may be fluctuating in concert with specific prey (i.e., alewives) whose populations are changing relative to environmental conditions and ecosystem disturbances. Remaining questions, however, are whether or not “natural” fluctuations in predator and prey provide enough “stability” in the Great Lakes food webs, and even more importantly, would a choice by managers to attempt to reduce the severity of predator-prey oscillations be antagonistic to native fish restoration efforts. We argue that, on each of the Great Lakes, managers are pursuing

    2004-01-01

    Metal concentrations (Ag, As, Cd, Cu, Hg, Ni, Pb, Zn) were determined in the feathers and excreta of nestling great tits (Parus major), in their main invertebrate prey (Lepidoptera larvae) and in vegetation samples, all collected from four sites along a pollution gradient. Metal contamination in vegetation samples increased significantly towards the pollution source. The Ag, As, Hg, Ni and Pb concentrations in food samples were significantly higher at the site closest to the pollution source compared to the other three sites. Great tit nestlings from the site closest to the pollution source had significantly higher concentrations of Ag, As, Hg and Pb in their excreta than did nestlings at the other three sites. For five metals (Ag, As, Cu, Ni and Pb), we found concentrations in caterpillars to be significantly positively correlated with vegetation samples. We also found clear significant positive correlations between excreta and caterpillars for Ag, As, Hg and Pb and between feathers and caterpillars for As and Pb. Our data suggest that excreta are a good monitor for the presence and concentrations of non-essential metals in the food and the environment of passerine birds

  6. The Study of Airline Merger and Acquisition in the Great China Area

    2003-01-01

    The Asian financial crisis in the late 20 th century has some long lasting effect on the air transportation industry in Asia, especially in the Great China Area. Starting from 1998, airlines in both China and Taiwan suffered some serious financial losses due to the diminishing travel demand caused by the economic recession. Airlines were forced to cut price to attract passengers and hence crashed the market discipline. A number of airline mergers and acquisitions were then driven by the markets and the governments. After China and Taiwan have both entered the World Trade Organization, some mega-merging cases were finalized in late 2002 for better fitting the world's aviation competitions. This paper reviews the nine merging and acquiring cases in the Great China Area in the past 5 years. Almost all the airlines in the area were involved. The new groups of airlines and the survival airlines are introduced. Market response to the airline mergers will also be examined. A general look over the performance of the new airlines will be discussed. And the future of the market will also be analyzed. Finally, the practices and the impacts of current inter-state mergers in the Great China Area will be examined. The study has expected a highly concentrated domestic market in both China and Taiwan. Each of the market will be dominated by three major airline groups of their own. Cross-holding equity within these 6 leading aviation groups would also be possible after further deregulations.

    Expansion of oil palm plantations has led to extensive wildlife habitat conversion in Southeast Asia [1]. This expansion is driven by a global demand for palm oil for products ranging from foods to detergents [2], and more recently for biofuels [3]. The negative impacts of oil palm development on biodiversity [1, 4, 5], and on orangutans (Pongo spp.) in particular, have been well documented [6, 7] and publicized [8, 9]. Although the oil palm is of African origin, Africa's production historically lags behind that of Southeast Asia. Recently, significant investments have been made that will likely drive the expansion of Africa's oil palm industry [10]. There is concern that this will lead to biodiversity losses similar to those in Southeast Asia. Here, we analyze the potential impact of oil palm development on Africa's great apes. Current great ape distribution in Africa substantially overlaps with current oil palm concessions (by 58.7%) and areas suitable for oil palm production (by 42.3%). More importantly, 39.9% of the distribution of great ape species on unprotected lands overlaps with suitable oil palm areas. There is an urgent need to develop guidelines for the expansion of oil palm in Africa to minimize the negative effects on apes and other wildlife. There is also a need for research to support land use decisions to reconcile economic development, great ape conservation, and avoiding carbon emissions. Copyright © 2014 Elsevier Ltd.

    Full Text Available Beginning with a characterization of contemporaneity (dominance of the financial sector and high technology, politicization of economy, ideological use of culture and control of the capacity for thought and a brief analysis of expansionism (political, economic, cultural on the eve of the Great War, the author embarks on a more detailed description of the spiritual situation in the wake of the Great War: in philosophy, literature, art, as well as the national-political programmatic texts and war propaganda publications of German intellectuals of the time. The continuity of the Austro-Hungarian colonial policy towards the Balkans and Serbia culminates in instigating a preventive war against Serbia by the elites in Berlin and Vienna, which is of importance with regard to the question of responsibility for the war, guided by concrete aims of war in which causes for war are reflected. These war elites wanted to declare the assassination in Sarajevo as the cause of war, which in fact was a political assassination and tyrannicide. The freedom movement of democratic youth, Mlada Bosna (Young Bosnia, needs to be viewed in the European context as inspired by the Serbian tradition of the cult of Kosovo and the ethics of Vidovdan (St Vitus' Day which speaks both about the victim's sacrifice as sublimation of history and about just suffering as elements of identity.

    Full Text Available The present paper has been written within the framework of a project called "Analysis of alternative experiences to tackle massive school failure in the surrounding urban areas of Buenos Aires". Two categories were considered relevant as a means to analyzing the complexity that characterises present-day state school institutions in the Great Buenos Aires area. The paper intends to reflect on the concept and meanings of border in social sciences, emphasizing its potential to better understand the practices that take place in state schools. The other category analysed is that of "school-family alliance", in order to understand its development during the last decades in view of the extreme poverty that permeates the area studied.

Most importantly, researchers should abandon the misleading practice of interpreting the results from inferential tests based solely on whether they are statistically significant (or not) and, instead, focus on reporting and interpreting effect sizes, confidence intervals, and significance levels. Nursing researchers also need to conduct and report a priori power analyses, and to address the issue of Type I experiment-wise error inflation in their studies. Crown Copyright © 2013.

    Between the North American Great Lakes and their tributaries are the places where the confluence of river and lake waters creates a distinct ecosystem: the rivermouth ecosystem. Human development has often centered around these rivermouths, in part, because they provide a rich array of ecosystem services. Not surprisingly, centuries of intense human activity have led to substantial pressures on, and alterations to, these ecosystems, often diminishing or degrading their ecological functions and associated ecological services. Many Great Lakes rivermouths are the focus of intense restoration efforts. For example, 36 of the active Great Lakes Areas of Concern (AOCs) are rivermouths or areas that include one or more rivermouths. Historically, research of rivermouth ecosystems has been piecemeal, focused on the Great Lakes proper or on the upper reaches of tributaries, with little direct study of the rivermouth itself. Researchers have been divided among disciplines, agencies and institutions; and they often work independently and use disparate venues to communicate their work. Management has also been fragmented with a focus on smaller, localized, sub-habitat units and socio-political or economic elements, rather than system-level consideration. This Primer presents the case for a more holistic approach to rivermouth science and management that can enable restoration of ecosystem services with multiple benefits to humans and the Great Lakes ecosystem. A conceptual model is presented with supporting text that describes the structures and processes common to all rivermouths, substantiating the case for treating these ecosystems as an identifiable class.1 Ecological services provided by rivermouths and changes in how humans value those services over time are illustrated through case studies of two Great Lakes rivermouths—the St. Louis River and the Maumee River. Specific ecosystem services are identified in italics throughout this Primer and follow definitions described

    The possible effects of radiation from fallout on childhood leukaemia mortality from 1950 to 1987 and registrations from 1963 to 1987 were assessed using a division of Great Britain into regions with higher rainfall and a consequently higher fallout radiation dose in the 1960s and regions with lower rainfall and a lower radiation dose. Childhood leukaemia mortality rates declined and registration rates increased throughout the period. For ages 0-14 years, the differences between rates in wet regions and dry regions were small and appeared unrelated to periods of low, medium and high radiation exposure based on dose equivalent to the red bone marrow after birth. For the 0-4 years age group the highest ratios of leukaemia death rates and registration rates in the wet compared with the dry part of Great Britain occurred in the period of highest radiation exposure after birth. The death rate ratio was significantly raised in the period of high exposure compared with the surrounding medium exposure periods, but the difference in registration rate ratios between the high exposure period and the medium exposure period following was not statistically significant. The results might be explained by survival and registration changes, or chance in the case of registrations, but do not exclude the possibility that low doses of radiation from fallout were responsible for an increased risk of leukaemia in young children in Great Britain.

    Full Text Available The appearance of new conceptual approaches and trends in modern historiography, changing the contents and the source base on the history of the Great Patriotic War created new opportunities for the study of the history of everyday life, the “human dimension” of the war. As part of the article the war daily life is considered through the prism of one of the stories of the children’s and teenagers’ life in militarized space – the reality of consolidated pastime. Daily practice of this social category is the least studied in the historical literature. Leisure activities occupied a significant place in the structure of everyday life of children and teenagers during the war. Its organization both for military and peacetime was formally regulated along with informal and personal time. Changes in the structure and filling the free time of students in a militarized space appeared in the content and the intensity of certain forms of leisure time, destructive tendencies, limited material and time resources. The greatest amount of free time of the younger generation was in the informal, unregulated practice of leisure, the solution of domestic problems and housework. Due to objective circumstances of the wartime the role of the family, educational, cultural and entertainment establishments in the life of children and adolescents significantly fell. Thus, during the war a street became the center of their “leisure routine,” including asocial orientation. Free time proceeded among coevals; there was a formation of personality and values. Partly the formal structures responsible for leisure activities of students, in particular, hobby clubs, is a tool for their inclusion in the process of providing possible assistance for front and rear and give them the skills necessary in combat. At the same time unauthorized, individual leisure had a relaxing effect contributed to the displacement of negative emotions, lifting the state of anxiety and fear

    In 1999, NEL developed the transmit-receive type ECT array probe for steam generator (SG) tubing, called 'X-probe', in cooperation with foreign firms. Recently NEL has developed the advanced ECT array probe, 'Smart Array Probe', characterized with a significantly improved resolution for circumferential cracks. The doubled channels in the circumferential mode have greatly improved the circumferential resolution of Smart Array Probe. With all the circumferential mode channels on the same circle, there is no need for axial position correction of inspection data. This report describes both the field practical performance and the compliance assessment to a Japanese SG-ECT guideline 'JEAG4208' of Smart Array ECT System, composed of Smart Array Probe, pusher-in-tester 'OMNI-200', and NEL's ECT Analysis System.

    Angelov, V.; Bonchev, Ts.; Mavrodiev, V.; Kyrdzhilov, N.

    1995-01-01

    In order to facilitate quantitative and qualitative characterisation of radioactive contamination the authors introduce a relative estimate of radionuclide activity by setting as a reference the most abundant element -Co-60 in the case of the Kozloduy NPP. The ratio η i of the mean annual permissible concentration in air for each radionuclide (RPC-92) to that of Co-60 is calculated. It is found that η i has the same or close values for groups of radionuclides, e.g. η i = 2.10 -4 for 238 Pu, 239 Pu, 240 Pu, 241 Am, 244 Cm; η i = 5 for 89 Sr, 91 Y; 93 Nb, 134 Cs, 137 Cs; η i = 50 for 55 Fe, 63 Ni, 95 Zr, 95 Nb, 140 Ba, 140 La. Then it is compared to the experimentally measured values of the same quantity η iexp , derived from surface contamination data. The ratio η iexp /η i is plotted against log η i . The resulting nomograms give graphic representation of the radiobiological significance of various radionuclide groups. Data from different locations at the Kozloduy NPP are presented. It is found that the alpha emitter contamination has highest values in the Unit 1 (WWER-440) control rooms after repair. The Unit 5 (WWER-1000) has lower alpha contamination compared to WWER-440 units. 1 ref., 5 figs., 1 tab

  18. The research and practice based on the full-time visitation model in clinical medical education

    Full Text Available Most of the higher medical colleges and universities teaching hospital carry certain clinical teaching tasks, but the traditional teaching pattern of "two stage", including the early stage of the theory of teaching, the late arrangement of clinical practice, had some drawbacks such as practice time is too concentrated and the chasm between students' theory and practice. It is suggested that students contact clinical diagnosis and treatment earlier, visit more patients and increase the ratio of visitation and course. But as more and more students flood into university, clinical visitation has turned into a difficulty to improve students’ ability. To resolve this problem, we have made some efficient practice and exploration in Rizhao City People's Hospital from September 2005 to July 2014. The students were divided into full-time visitation model group and “two stage” pattern group randomly. The single factors are of great difference between the two groups. The full-time visitation model in clinical medical education builds a new mode of practice of clinical practice teaching in the medical stuents' concept of doctor-patient communication, humanistic care to patients, basic theoretical knowledge, clinical practice skills and graduate admission rate increased significantly. Continuous improvement of OSCE exam is needed to make evaluation more scientific, objective and fair.

  19. The Great Depression and the Great Recession: A Comparative Analysis of their Analogies

    Directory of Open Access Journals (Sweden)

    Cristina Peicuti

    2014-06-01

    Full Text Available The decades preceding the Great Depression and the U.S. subprime mortgage crisis have close similarities. Both decades were characterized by rapid growth without major contractions, by an increase in liquidity, a lack of inflation, and a generalized decrease in risk premiums. Additional similarities included significant changes in the financing of real estate by commercial banks along with a consolidation of the banking sector and high hopes that the efficiency of monetary policy would prevent financial crises. These decades were also characterized by the consolidation of the powers of young central banks (the Federal Reserve System in the 1920s and the European Central Bank in the 2000s, by unsuccessful attempts to control market speculation, by their international dimensions, and by the eruption of crises after the failure of a major American financial institution that could have been avoided. Understanding these analogies help us better identify the causes of the subprime mortgage crisis and prevent history from repeating itself to the extentof such large-scale devastating consequences.

    Thirteen polymorphic microsatellite markers were isolated and characterized from the great hornbill, Buceros bicornis. In analyses of 20 individuals, the numbers of alleles per locus varied from two to 11. The expected and observed heterozygosities ranged from 0.22 to 0.88 and from 0.20 to 1.00, respectively. The mean polymorphic information content was 0.62. Among these, three loci deviated from the Hardy-Weinberg equilibrium. However, no significant genotypic disequilibrium was detected between any pair of loci. These microsatellite markers are useful for the population genetic study of the great hornbill. © 2009 The Authors. Journal compilation © 2009 Blackwell Publishing Ltd.

    2018-04-01

    : The Great London Smog of December 1952 lasted five days and killed up to 12,000 people. The smog developed primarily because of extensive burning of high-sulfur coal. The health effects were both immediate and long lasting, with a recent study revealing an increased likelihood of childhood asthma development in those exposed to the Great Smog while in utero or during their first year of life. Subsequent pollution legislation-including the U.S. Clean Air Act and its amendments-have demonstrably reduced air pollution and positively impacted health outcomes. With poor air quality events like the Great Smog continuing to occur today, nurses need to be aware of the impact such environmental disasters can have on human health.

    The small group of recently discovered galactic globular clusters (Pal 12, Ter 7, Rup 106, Arp 2) significantly younger than the average cluster population of the Galaxy are shown to lie near great circles passing in the proximity of most satellite galaxies of the Milky Way. Assuming that these great circles are in some way preferential planes of interaction between the Galaxy and its companions, the authors identified along one of them another candidate "young" globular cluster, IC 4499. Within this observational framework, the possibility that the sample of young globulars found in the halo of the Galaxy could have been captured from a satellite galaxy or formed during a close interaction between the Milky Way and one of its companions is briefly discussed.

    The old standard dental practice of yesterday, with a stubborn dentist who thinks marketing and advertising (concepts key to retail establishment success) are "unethical" doesn't cut it anymore. The practical retail concepts discussed about in this article allow dentists to create a marketing and professionalism hybrid. Providing first-class, customer-service treatment is the underlying principle. Patients who feel their dentist and staff know them will always feel at ease and a great sense of loyalty. The reward for treating patients like customers, consumers, and friends is that patients patronize businesses, including dental practices that meet or exceed their expectations.

  7. “Remembering with advantages”: The memory of the Great War in Australia

    Directory of Open Access Journals (Sweden)

    Carolyn Holbrook

    2015-02-01

    Full Text Available Australian memory of the Great War has always been expressed most enthusiastically in the rituals of Anzac Day: an occasion that recognises the anniversary of the Australians’ first battle of the war in Turkey on 25 April 1915. In the decades after 1914–1918, the devastating effects of the war were assuaged in part by the pride that Australians felt in the fighting reputation of their soldiers. By the 1960s the rituals of Anzac were in noticeable decline. Young Australians were hostile to the values of the Great War generation and believed that the commemorative practices of Anzac Day glorified war. Despite the widespread belief that Anzac Day would die with the last of the old veterans, it has staged a remarkable resurgence. This can be explained by the remaking of the Anzac legend, from a myth anchored in British race patriotism and martial nationalism to one that speaks in the modern idiom of trauma, suffering and empathy. What remains of the original Anzac legend is the belief commonly held by contemporary Australians that their national consciousness was born at Gallipoli on 25 April 1915.

    To examine the association between the Great Recession of 2007-2009 and health care expenditures along the health care spending distribution, with a focus on racial/ethnic disparities. Secondary data analyses of the Medical Expenditure Panel Survey (2005-2006 and 2008-2009). Quantile multivariate regressions are employed to measure the different associations between the economic recession of 2007-2009 and health care spending. Race/ethnicity and interaction terms between race/ethnicity and a recession indicator are controlled to examine whether minorities encountered disproportionately lower health spending during the economic recession. The Great Recession was significantly associated with reductions in health care expenditures at the 10th-50th percentiles of the distribution, but not at the 75th-90th percentiles. Racial and ethnic disparities were more substantial at the lower end of the health expenditure distribution; however, on average the reduction in expenditures was similar for all race/ethnic groups. The Great Recession was also positively associated with spending on emergency department visits. This study shows that the relationship between the Great Recession and health care spending varied along the health expenditure distribution. More variability was observed in the lower end of the health spending distribution compared to the higher end. © Health Research and Educational Trust.

    There has in recent years been great concern about possible cardiac side effects of thiazolidinediones (TZDs). We present a case-report of a 60 year-old male who developed significant mitral regurgitation during six months treatment with pioglitazone in parallel with laboratory indications of fluid retention. Echocardiography six months after discontinuation of medication showed regression of mitral regurgitation and the laboratory parameters were also normalized. It is noteworthy that six months treatment with pioglitazone could induce significant valve dysfunction, which was reversible, and this underlines the importance of carefully monitoring patients when placing them on treatment with TZDs.

    2014-12-01

    Tsunamis have inflicted death and destruction on the coastlines of the world throughout history. The occurrence of tsunamis and the resulting effects have been collected and studied as far back as the second millennium B.C. The knowledge gained from cataloging and examining these events has led to significant changes in our understanding of tsunamis, tsunami sources, and methods to mitigate the effects of tsunamis. The most significant, not surprisingly, are often the most devastating, such as the 2011 Tohoku, Japan earthquake and tsunami. The goal of this poster is to give a brief overview of the occurrence of tsunamis and then focus specifically on several significant tsunamis. There are various criteria to determine the most significant tsunamis: the number of deaths, amount of damage, maximum runup height, had a major impact on tsunami science or policy, etc. As a result, descriptions will include some of the most costly (2011 Tohoku, Japan), the most deadly (2004 Sumatra, 1883 Krakatau), and the highest runup ever observed (1958 Lituya Bay, Alaska). The discovery of the Cascadia subduction zone as the source of the 1700 Japanese "Orphan" tsunami and a future tsunami threat to the U.S. northwest coast, contributed to the decision to form the U.S. National Tsunami Hazard Mitigation Program. The great Lisbon earthquake of 1755 marked the beginning of the modern era of seismology. Knowledge gained from the 1964 Alaska earthquake and tsunami helped confirm the theory of plate tectonics. The 1946 Alaska, 1952 Kuril Islands, 1960 Chile, 1964 Alaska, and the 2004 Banda Aceh, tsunamis all resulted in warning centers or systems being established.The data descriptions on this poster were extracted from NOAA's National Geophysical Data Center (NGDC) global historical tsunami database. Additional information about these tsunamis, as well as water level data can be found by accessing the NGDC website www.ngdc.noaa.gov/hazard/

Established Federal programs that are overseen by the National Oceanic and Atmospheric Administration (NOAA) and the U.S. Army Corps of Engineers (USACE) are responsible for most of the existing watershed models for specific tributaries. The NOAA Great Lakes Environmental Research Laboratory (GLERL) uses the Large Basin Runoff Model to provide data for the management of water levels in the Great Lakes by estimating United States and Canadian inflows to the Great Lakes from 121 large watersheds. GLERL also simulates streamflows in 34 U.S. watersheds by a grid-based model, the Distributed Large Basin Runoff Model. The NOAA National Weather Service uses the Sacramento Soil Moisture Accounting model to predict flows at river forecast sites. The USACE created or funded the creation of models for at least 30 tributaries to the Great Lakes to better understand sediment erosion, transport, and aggradation processes that affect Federal navigation channels and harbors. Many of the USACE hydrologic models have been coupled with hydrodynamic and sediment-transport models that simulate the processes in the stream and harbor near the mouth of the modeled tributary. Some models either have been applied or have the capability of being applied across the entire Great Lakes Basin; they are (1) the SPAtially Referenced Regressions On Watershed attributes (SPARROW) model, which was developed by the USGS; (2) the High Impact Targeting (HIT) and Digital Watershed models, which were developed by the Institute of Water Research at Michigan State University; (3) the Long-Term Hydrologic Impact Assessment (L–THIA) model, which was developed by researchers at Purdue University; and (4) the Water Erosion Prediction Project (WEPP) model, which was

    The Mizunami underground research laboratory is planned to consist of greatly deeper shaft and horizontal drifts. A junction space between a greatly deeper shaft and horizontal drifts forms which would take a complicated mechanical behavior during a junction excavation. However, a quantitative design method of supporting measures for a deep junction has not yet been established. This is because a conventional shaft design has been conducted based on past experience. Detail records have not been left either in what kind of collapses and deformed phenomena occurring in shaft constructions in a past. In order to examine a collapse mechanism of greatly deeper shaft junction, we have conducted literature surveys and interview studies concerned with deep shaft construction works in a past, and investigated what collapses or difficulties had been occurred in deep shaft junctions. Considering the results of investigations with reviews of intellectuals, a collapse mechanism of a super deep shaft junction depends on both a construction procedure of shaft junction and a geological condition at great depth. During a construction of a shaft junction, stress state of rock masses near junction wall would take a complicated stress path. Especially, it should be necessary to take a most careful consideration on that tangential stress acted around a shaft wall may reduce during horizontal drift excavation. On the other hand, where greatly deeper junction intersects faults and/or fractures with a large angle, a collapse called 'Take-nuke' may occur or extraordinary earth pressure acts on a concrete wall. This is the most typical difficulties during shaft construction. In order to recognize a mechanism of these phenomena and to find out a cause of collapse generation, numerical studies that can simulate a practical rock mass behavior around a shaft junction should be carry out. We demonstrate the finite difference method is most adequate for these simulations with intellectual review

    Medical practice is inherently ambiguous and uncertain. The physicians' ability to tolerate ambiguity and uncertainty has been proved to have a great impact on clinical practice. The primary aim of the present study was to test the hypothesis that higher degree of physicians' ambiguity and uncertainty intolerance and higher need for cognitive closure will predict higher work stress. Two hundred and twelve physicians (mean age = 42.94 years; SD = 10.72) from different medical specialties with different levels of expertise were administered a set of questionnaires measuring perceived levels of work-related stress, individual ability to tolerate ambiguity, stress deriving from uncertainty, and personal need for cognitive closure. A linear regression analysis was performed to examine which variables predict the perceived level of stress. The regression model was statistically significant [R 2  = .32; F(10,206) = 8.78, p ≤ .001], thus showing that, after controlling for gender and medical specialty, ambiguity and uncertainty tolerance, decisiveness (a dimension included in need for closure), and the years of practice were significant predictors of perceived work-related stress. Findings from the present study have some implications for medical education. Given the great impact that the individual ability to tolerate ambiguity and uncertainty has on the physicians' level of perceived work-related stress, it would be worth paying particular attention to such a skill in medical education settings. It would be crucial to introduce or to empower educational tools and strategies that could increase medical students' ability to tolerate ambiguity and uncertainty.

    Australia's Great Sandy Region is of international significance containing two World Heritage areas and patches of rainforest growing on white sand. Previous broad-scale analysis found the Great Sandy biogeographic subregion contained a significantly more phylogenetically even subset of species than expected by chance contrasting with rainforest on white sand in Peru. This study aimed to test the patterns of rainforest diversity and relatedness at a finer scale and to investigate why we may find different patterns of phylogenetic evenness compared with rainforests on white sands in other parts of the world. This study focussed on rainforest sites within the Great Sandy and surrounding areas in South East Queensland (SEQ), Australia. We undertook field collections, expanded our three-marker DNA barcode library of SEQ rainforest plants and updated the phylogeny to 95% of the SEQ rainforest flora. We sampled species composition of rainforest in fixed area plots from 100 sites. We calculated phylogenetic diversity (PD) measures as well as species richness (SR) for each rainforest community. These combined with site variables such as geology, were used to evaluate patterns and relatedness. We found that many rainforest communities in the Great Sandy area were significantly phylogenetically even at the individual site level consistent with a broader subregion analysis. Sites from adjacent areas were either not significant or were significantly phylogenetically clustered. Some results in the neighbouring areas were consistent with historic range expansions. In contrast with expectations, sites located on the oldest substrates had significantly lower phylogenetic diversity (PD). Fraser Island was once connected to mainland Australia, our results are consistent with a region geologically old enough to have continuously supported rainforest in refugia.

    GREAT (Genome REgulatory Architecture Tools) is a novel web portal for tools designed to generate user-friendly and biologically useful analysis of genome architecture and regulation. The online tools of GREAT are freely accessible and compatible with essentially any operating system which runs a modern browser. GREAT is based on the analysis of genome layout -defined as the respective positioning of co-functional genes- and its relation with chromosome architecture and gene expression. GREAT tools allow users to systematically detect regular patterns along co-functional genomic features in an automatic way consisting of three individual steps and respective interactive visualizations. In addition to the complete analysis of regularities, GREAT tools enable the use of periodicity and position information for improving the prediction of transcription factor binding sites using a multi-view machine learning approach. The outcome of this integrative approach features a multivariate analysis of the interplay between the location of a gene and its regulatory sequence. GREAT results are plotted in web interactive graphs and are available for download either as individual plots, self-contained interactive pages or as machine readable tables for downstream analysis. The GREAT portal can be reached at the following URL https://absynth.issb.genopole.fr/GREAT and each individual GREAT tool is available for downloading. © The Author(s) 2016.

    Orthopaedic residents and attending physicians who report having a supportive spouse show lower levels of burnout and psychological distress than those without supportive spouses. However, little is known about the experiences of the spouses. This nationwide study examines burnout, psychological distress, and marital satisfaction of the spouses and significant others (collectively referred to hereafter as spouses) of orthopaedists in training and in orthopaedic practice in an academic setting. Employing previously reported methodology, 259 spouses of orthopaedic residents and 169 spouses of full-time orthopaedic faculty completed a voluntary, anonymous survey. The survey included three validated instruments (the Maslach Burnout Inventory, the General Psychological Health Questionnaire-12, and the Revised Dyadic Adjustment Scale) and three novel question sets addressing demographic information, relationship issues, stress, and work/life balance. Psychological distress was noted in 18% of resident spouses compared with only 10% of faculty spouses (p = 0.014). Resident spouses reported greater loneliness (p < 0.0009) and stress (p = 0.03) than faculty spouses. Among working spouses, 30% of resident spouses and 13% of faculty spouses showed high levels of emotional exhaustion (p < 0.003). Twenty-eight percent of employed resident spouses and 5% of employed faculty spouses showed problematic levels of depersonalization (p < 0.0001). Twenty-six percent of employed resident spouses and 12% of employed faculty spouses showed a diminished sense of personal accomplishment (p = 0.012). Marital satisfaction was high for both resident and faculty spouses. Decreased satisfaction correlated with excessive mate irritability and fatigue that precluded their mate's involvement in family activities. A gratifying sex life, full-time work outside the home, and spending more than ninety minutes a day with their mate correlated significantly with marital satisfaction. Many orthopaedic

    The purpose of this preliminary study was to evaluate the prospects for using populations of the great tit (Parus major) and the pied flycatcher (Ficedula hypoleuca) in ecological monitoring of territories contaminated with radionuclides. Studies were performed in the summer of 1992 in birch forests of the Southern Urals. Artificial nesting sites (log houses) located 1.5 m above the ground were distributed over territories of two test plots: 30 log houses on the contaminated plot and 60 on the control plot (contamination with Sr-90 1.5 and 2 · 10 -3 mCi/m 2 , respectively). The nesting success in the great tit was similar on both plots, whereas that in the pied flycatcher was significantly greater on the control plot (in a open-quotes cleanclose quotes forest). Pied flycatchers build their nests out of highly radioactive materials, whereas great tits use nonradioactive or weakly emitting materials. Hence, pied flycatcher's nestlings receive a significant radiation dose from components of the nest: From the moment of egg laying, this dose amounts to 0.5 rem. The pied flycatcher can be used as an indicator of radioactive contamination. This species is more sensitive than the great tit, which has been successfully used as an indicator for monitoring the industrial air pollution

    A Cross-sectional survey was carried out to determine the environmental and personal hygiene practices of mothers of children aged less than five years in two markets in Ibadan--one with poor sanitary conditions (Bodija) and the other one with better sanitation facilities (Gbagi). The study sought to identify the risk factors for diarrhoea among these children. Two hundred and sixty-six mothers in Bodija and 260 in Gbagi were interviewed. A questionnaire was used for collecting information on social and demographic characteristics, personal and environmental hygiene practices, including sources of food and water for their children, waste-disposal practices and occurrence of diarrhoea among their children aged less than five years. The educational status of the women in Bodija was lower than that of the women in Gbagi (p homes, and 45 (17%) bought it from vendors in the market. The corresponding figures for women of the Gbagi market were 41 (16%), 98 (38%) and 19 (7%). Two hundred and thirty-four (90%) women in Gbagi prepared breakfast at home for their children compared to 216 (81%) women in Bodija. This difference was statistically significant (p Waste disposal and personal hygiene practices were poorer among the women in Bodija. Yet the occurrence of diarrhoea was not significantly different in both the markets. Risk factors for diarrhoea identified in this study were water and food bought from vendors, child defaecation practices, mothers' cleaning up practices after child's defaecation, and refuse-disposal practices. The inherent risk of sale of unwholesome food and water by vendors is a great concern for public health authorities in Nigeria. Efforts to control diarrhoea must not only be focused on improving mothers' knowledge about food hygiene but also on environmental hygiene practices within the community.

  10. An ecosystem approach to the health effects of mercury in the Great Lakes basin ecosystem

    2004-01-01

    New concerns about the global presence and human health significance of mercury have arisen as a result of recent epidemiological data demonstrating subtle neurological effects from consumption of mercury-contaminated fish. In the Great Lakes Basin, the complexity of the diverse sources, pools, and sinks of mercury and of the pathways of distribution, fate, and biotransformation requires an ecosystem approach to the assessment of exposures of Great Lakes' human populations. Further epidemiological research is needed to verify preliminary indications of harmful effects in people living near the Great Lakes. Great Lakes fish are valuable resources for subsistence nutrition, recreation, and commerce, but the benefits of fish consumption must be balanced by concern for the hazards from the contaminants that they may contain. The efficacy of fish consumption advisories in reducing exposures should continue to be evaluated while planning continues for remedial actions on contaminated sediments from historic industrial activities and for regulatory action to control sources

    Scope of practice, competencies, and philosophy of maternity practice are similar among midwives in the United States and Canada. However, there are marked differences in intrapartum practice sites between registered midwives (RMs) and certified nurse-midwives (CNMs). This study linked data from 2 national surveys: 1) a 2007 survey of CNM members of the American College of Nurse-Midwives (n = 1893); and 2) the Canadian Birth Place Study of maternity providers, including RM members of the Canadian Association of Midwives (n = 451) to compare the demographics, practice experience, and attitudes to home birth between these 2 types of North American midwives. A Provider Attitudes To Planned Home Birth scale-international (PAPHB-i) was developed for this analysis. Descriptive and bivariate analyses are presented. Educational exposure to planned home birth varied greatly when comparing CNMs and RMs, as did practice patterns regarding continuity of care, primary and gynecologic care, and involvement with research and teaching. Registered midwives were almost 4 times more likely than CNMs to have practiced in the home (99.1% vs 26.0%). Certified nurse-midwives scored significantly lower than RMs on the PAPHB-i scale (36.5 vs 41.0), indicating less favorable attitudes toward home birth overall. Certified nurse-midwives were less confident than RMs in their management skills for home birth practice. Age, exposure to planned home birth during midwifery education, and practice experience in the home setting emerged as significant covariates of attitudes toward home birth. Significantly more RMs and CNMs with home birth experience expressed concerns about disapproval of hospital-based peers, but they were significantly less likely to agree that midwives face other systemic barriers than CNMs with no home birth experience. Differences in favorability toward and confidence with practice during planned home births among CNMs and RMs were predicted associated with differences in

    The concentrations of fallout 239 240 Pu in the surface waters from all the Great Lakes were slightly lower in 1976 samples than in those from 1973. The same trend of higher concentrations in the surface waters of the upper lakes as in the surface waters of the lower lakes was observed for both years. In addition, the 239 240 Pu concentration in samples of deep water collected during the summer of 1976 was higher than in the surface waters but was similar to the surface water values of the 1973 spring samples. This observation is significant in that it suggests that the surface waters of all the Great Lakes undergo a seasonal decrease in plutonium concentration similar to that already observed in Lake Michigan

    Purpose: The Radiation Incident and Safety Committee (RISC), established and supported by Cancer Care Ontario (CCO), is responsible for advising the Provincial Head of the Radiation Treatment program on matters relating to provincial reporting of radiation incidents with the goal of improved risk mitigation. Methods: The committee is made up of Radiation Incident Leads (RILs) with representation from each of the 14 radiation medicine programs in the province. RISC routinely meets to review recent critical incidents and to discuss provincial reporting processes and future directions of the committee. Regular face to face meetings have provided an excellent venue for sharing incident learning practices. A summary of the incident learning practices across Ontario has been compiled. Results: Almost all programs in Ontario employ an incident learning committee to review incidents and identify corrective actions or process improvements. Tools used for incident reporting include: paper based reporting, a number of different commercial products and software solutions developed in-house. A wide range of classification schema (data taxonomies) are employed, although most have been influenced by national guidance documents. The majority of clinics perform root cause analyses but utilized methodologies vary significantly. Conclusions: Most programs in Ontario employ a committee approach to incident learning. However, the reporting tools and taxonomies in use vary greatly which represents a significant challenge to provincial reporting. RISC is preparing to adopt the National System for Incident Reporting – Radiation Therapy (NSIR-RT) which will standardize incident reporting and facilitate data analyses aimed at identifying targeted improvement initiatives.

    Full Text Available The conception of sustainable development has been implemented into practice in numerous economic sectors, including forestry. Forest ecosystems are extremely important in the global ecological system, therefore maintenance and appropriate management of forest resources according to sustainable development principles have engaged a great deal of attention. The concept of sustainable forest management (SFM encompasses three dimensions: ecological, economic and social. A powerful tool to promote SFM are criteria and indicators. The aim of the article was evaluation of SFM in Poland, using one of the methods proposed by the Food and Agriculture Organization (FAO. According to data available, Polish forestry has a number of advantages: Poland has avoided the problem of deforestation, forest area has been permanently increasing, there has been observed improvement of forest health and vitality as well as a significant share of forests has carried out protective functions with no impact on timber production. Poland’s model of SFM is an adaptive process of balancing the ever-changing set of economic, environmental and social expectations. Such a complicated undertaking requires constant assessing and adjusting forest practices, in response to new circumstances, scientific advances and societal input

    Due to tsunami triggered by the Great East Japan Earthquake, the operating and refueling reactor facilities at Fukushima Dai-ichi and Dai-ni Nuclear Power Plants caused a nuclear hazard. Given the fact, Japanese electric power companies voluntarily began to compile various urgent measures against tsunami. And then the Nuclear and Industrial Safety Agency (NISA) ordered the licensees to put into practice the voluntarily compiled urgent safety measures, in order to ensure the effectiveness of the means for recovering cooling functions along with avoiding the release of radioactive substances to the possible minimum, even if a huge tsunami following a severe earthquake hits nuclear power plants. The following describes the state and the effect of the urgent safety measures implemented for 44 reactors (under operation) and 1 reactor (under construction) in Japan and also describes the measures to be implemented by the licensees of reactor operation in the future.

  3. Great Basin geologic framework and uranium favorability

    Larson, L.T.; Beal, L.H.

    1978-01-01

    Work on this report has been done by a team of seven investigators assisted over the project span by twenty-three undergraduate and graduate students from May 18, 1976 to August 19, 1977. The report is presented in one volume of text, one volume or Folio of Maps, and two volumes of bibliography. The bibliography contains approximately 5300 references on geologic subjects pertinent to the search for uranium in the Great Basin. Volume I of the bibliography lists articles by author alphabetically and Volume II cross-indexes these articles by location and key word. Chapters I through IV of the Text volume and accompanying Folio Map Sets 1, 2, 3, 4, and 5, discuss the relationship of uranium to rock and structural environments which dominate the Great Basin. Chapter 5 and Map Sets 6 and 7 provide a geochemical association/metallogenic grouping of mineral occurrences in the Great Basin along with information on rock types hosting uranium. Chapter VI summarizes the results of a court house claim record search for 'new' claiming areas for uranium, and Chapter VII along with Folio Map Set 8 gives all published geochronological data available through April 1, 1977 on rocks of the Great Basin. Chapter VIII provides an introduction to a computer analysis of characteristics of certain major uranium deposits in crystalline rocks (worldwide) and is offered as a suggestion of what might be done with uranium in all geologic environments. We believe such analysis will assist materially in constructing exploration models. Chapter IX summarizes criteria used and conclusions reached as to the favorability of uranium environments which we believe to exist in the Great Basin and concludes with recommendations for both exploration and future research. A general summary conclusion is that there are several geologic environments within the Great Basin which have considerable potential and that few, if any, have been sufficiently tested

    A pilot survey of radiological protection in dental practice in Great Britain has been requested by the Health and Safety Executive and is now in progress. The survey should provide more precise data on the use of X-ray equipment. There are approximately 13,000 dentists in Great Britain using X-ray apparatus, and some 600 of these have been selected, on a statistical basis, to be invited to make use of a postal survey over a six month period. The postal survey technique to be used has already been developed as a service following requests from individual dentists. The dentist receives a questionnaire and three initial films to test the timer, then two special cassettes incorporating film and filters. Film badges are worn over a 12 week period by the dentist and by any staff who assist in radiography. Follow-up visits to discuss the survey will be made to one in ten of the selected dentists. The results will give the individual dentists, without cost, assurance of the efficient functioning of their equipment, and advice, should any remedial measures be necessary. Concurrently, the resulting statistics will give an indication of how many, if any, practices fall short of the recommendations of the Code of Practice for the Protection of Persons against Ionizing Radiations arising from Medical and Dental Use. Further action in respect of the Health and Safety at Work Act will be determined in the light of the survey.

    Climate change is now considered the greatest long-term threat to coral reefs, with some future change inevitable despite mitigation efforts. Managers must therefore focus on supporting the natural resilience of reefs, requiring that resilient reefs and reef regions be identified. We develop a framework for assessing resilience and trial it by applying the framework to target management responses to climate change on the southern Great Barrier Reef. The framework generates a resilience score for a site based on the evaluation of 19 differentially weighted indicators known or thought to confer resilience to coral reefs. Scores are summed, and sites within a region are ranked in terms of (1) their resilience relative to the other sites being assessed, and (2) the extent to which managers can influence their resilience. The framework was applied to 31 sites in Keppel Bay of the southern Great Barrier Reef, which has a long history of disturbance and recovery. Resilience and ‘management influence potential’ were both found to vary widely in Keppel Bay, informing site selection for the staged implementation of resilience-based management strategies. The assessment framework represents a step towards making the concept of resilience operational to reef managers and conservationists. Also, it is customisable, easy to teach and implement and effective in building support among local communities and stakeholders for management responses to climate change.

    Community pharmacy practice in Australia is changing and Research and Development (R&D) in community pharmacy plays an important role in contributing to the changes. A range of Cognitive Pharmacy Services (CPS) were developed from R&D programs, yet their implementation has been minimal indicating slow practice change within community pharmacy. Given the vital role of R&D, little is known about the operation and the extent to which it has been effective in supporting practice change in community pharmacy. In depth, semi-structured interviews were conducted with 27 key stakeholders in the pharmacy and healthcare system in Australia. All interviews were audio-recorded, transcribed ad verbatim and analysed using an inductive approach. Participants perceived that the R&D program has played an important role in the advent of CPS. Furthermore, they considered that evidence generated by the R&D projects is a critical influence on policy formulation, funding and implementation of CPS into practice. However, policy decisions and subsequent implementation are also influenced by other factors associated with context and facilitation which in turn foster or inhibit effective Knowledge Translation (KT) in the community pharmacy sector. While R&D programs have been viewed as essential for supporting changes in community pharmacy practice through development and funding of CPS, the overall impact has been small, as contemporary practice continues to be predominantly a dispensing model. Given the complexity and dynamic nature of the community pharmacy system, stakeholders must take into account the inter-relationship between context, evidence and facilitation for successful KT in community pharmacy practice.

    Although feminist social work has been practiced in Israel since the 1970s, little has been written about it. This qualitative study aims to fill this gap by documenting and conceptualizing feminist theory of practice and actual practice based on interviews with 12 feminist social workers. Findings reveal that the interviewees perceive feminist practice as significantly different from traditional social work practice based on four analytical principles: (1) gender analysis, (2) awareness of power relations, (3) analysis of welfare services as structures of oppression, and (4) utilization of feminist language, as well as 10 principles of action. The principles are discussed in the context of feminist social work in Israel and in light of feminist principles described in international literature.

    Water clarity trends in three upper Great Lakes, Lakes Superior, Michigan, and Huron, were assessed via satellite imagery from 1998 to 2012. Water attenuation coefficients (Kd490) from SeaWiFS and Aqua MODIS satellites compared favorably with in situ measurements. Significant temporal and spatial trends and differences in Kd490 were noted within all three of the lakes. Lake-wide average Kd490 for Lake Superior did not exhibited any changes between 1998 and 2012. Annual Kd490 values for Lake Huron, however, showed a significant negative trend during the study period using both SeaWiFS and MODIS datasets. Similarly, annual Kd490 values of Lake Michigan declined between 1998 and 2010. Additionally, Kd490 trend for depths >90m in northern Lake Michigan reversed (increased) after 2007. Photic depth increased significantly in both Lake Michigan (≃5m), and Lake Huron (≃10m) when comparing annual Kd490 for pre- (1998-2001) and post-mussel (2006-2010). At seasonal level, significant decreases in Kd490 in lakes Michigan and Huron were mainly noted for the spring/fall/winter mixing periods. After current changes in water clarity, lake-wide photic depths in lakes Michigan and Huron superseded Lake Superior; thus, making Lake Superior no longer the clearest Great Lake. Combination of several factors (filtering activities of quagga mussels [Dreissena bugensis rostriformis], phosphorus abatement, climate change, etc.) are likely responsible for these large changes.

    Fibrodysplasia ossificans progressiva (FOP) is a rare genetic disorder and the most disabling condition of heterotopic (extraskeletal) ossification in humans. Extraskeletal bone formation associated with inflammation preceding the osseous conversion usually begins in the first decade, predominantly in the head, neck, and shoulders. All patients have malformed great toes. Most patients have a spontaneous mutation of the ACVR1 gene. We report a 17-year-old girl with malformed great toes who had her first episode of heterotopic ossification and impaired mobility of the left hip at the age of 13 years. No inflammatory fibroproliferative masses preceded the onset of heterotopic ossification. Radiographic studies demonstrated myositis ossificans, but failure to associate the great toe malformation with heterotopic ossification led to a failure to diagnose FOP. She underwent repeated and unnecessary operative procedures to remove a recurrent lesion. FOP was finally suspected when the great toe malformation was correlated with the trauma-induced heterotopic ossification. Genetic analysis confirmed the presence of the classic FOP mutation (ACVR1 c.617G>A; R206H). This case highlights the importance of examining the great toes in anyone with heterotopic ossification. The association of malformations of the great toe with heterotopic ossification in all cases of classic FOP will lead to prompt clinical diagnosis and the prevention of iatrogenic harm.

    The practice of oncology can be a source of both great satisfaction and great stress. Although many oncologists experience burnout, depression, and dissatisfaction with work, others experience tremendous career satisfaction and achieve a high overall quality of life. Identifying professional goals, optimizing career fit, identifying and managing stressors specific to practice type, and achieving the optimal personal work-life balance can increase the likelihood of individual oncologists' achieving personal and professional satisfaction. In this article, we will explore how oncologists can accomplish these tasks and will examine several pervasive professional myths that often distort perspective. The article concludes in a conversation with four oncologists regarding what they find most meaningful about their work, how they manage career-specific stressors, and how they achieve balance between their personal and professional lives.

    The "Great Recession" lasted from December 2007 to June 2009, and it wreaked havoc on the revenues of state (and local) governments. While the U.S. economy has improved since the end of the Great Recession, state government revenues have in most cases still not completely recovered. We use various indicators to measure how different states have -- or have not -- recovered in the aftermath of the Great Recession, and we also attempt to explain why these different patterns of recovery have emer...

    2013-11-01

    Over half of general anesthetics in the UK involve supraglottic airway devices (SADs). The National Audit Project 4 undertaken by the Royal College of Anaesthetists demonstrated that aspiration was the most frequent complication relating to SAD use. SADs designed to reduce this risk (second-generation devices) are increasingly recommended in both adults and children. As well as routine use, SADs are recommended for use in cases of 'difficult airway'. This survey assessed current usage of SADs in routine practice and difficult airways. Sixteen questions, approved by the Association of Paediatric Anaesthetists of Great Britain and Ireland (APAGBI) survey committee, were distributed to all its members. Two hundred and forty-four members responded. Eighty-eight percent preferentially use first-generation rather than second-generation devices. The most important design feature was the availability of a complete range of sizes (84%). Seventy-seven percent felt that randomized controlled trials assessing SAD safety in children are needed. In cases of failed intubation, classically shaped SADs are preferred (79%). Three percent of responders intubate via an SAD routinely. Eighteen percent have employed this technique in an emergency. Thirty-six percent of responders have found an SAD to function poorly. Pediatric anesthesiologists appear slow to embrace second-generation SADs. The role of SADs in the management of difficult airways is widely accepted. Research currently has little influence over the choice of which SAD to use, which is more likely determined by personal choice and departmental preference. There is a risk that some SADs are unsafe. © 2013 John Wiley & Sons Ltd.

    Full Text Available Fractionation of biomass by filtration is a standard method for sampling planktonic microbes. It is unclear how the taxonomic composition of filtered biomass changes depending on sample volume. Using seawater from a marine oxygen minimum zone, we quantified the 16S rRNA gene composition of biomass on a prefilter (1.6 μm pore-size and a downstream 0.2 μm filter over sample volumes from 0.05 to 5 L. Significant community shifts occurred in both filter fractions, and were most dramatic in the prefilter community. Sequences matching Vibrionales decreased from ~40-60% of prefilter datasets at low volumes (0.05-0.5 L to less than 5% at higher volumes, while groups such at the Chromatiales and Thiohalorhabdales followed opposite trends, increasing from minor representation to become the dominant taxa at higher volumes. Groups often associated with marine particles, including members of the Deltaproteobacteria, Planctomycetes and Bacteroidetes, were among those showing the greatest increase with volume (4 to 27-fold. Taxon richness (97% similarity clusters also varied significantly with volume, and in opposing directions depending on filter fraction, highlighting potential biases in community complexity estimates. These data raise concerns for studies using filter fractionation for quantitative comparisons of aquatic microbial diversity, for example between free-living and particle-associated communities.

    Patient-reported outcome (PRO) is an "umbrella term" that covers a whole range of potential types of measurement but it is used specifically to refer to all measures quantifying the state of health through the evaluation of outcomes reported by the patient himself/herself. PROs are increasingly seen as complementary to biomedical measures and they are being incorporated more frequently into clinical trials and clinical practice. After considering the cultural background of PROs - that is the well known patient-centered model of medicine -, their historical profile (since 1914, the year of the first outcome measure) and typologies, the paper aims at debating their methodological complexity and implementation into practice. Some clinical trials and therapeutic managements utilizing patient-centered measures will be also analyzed.

  4. The origin of 'Great Walls'

    International Nuclear Information System (INIS)

    Shandarin, Sergei F.

    2009-01-01

    A new semi-analytical model that explains the formation and sizes of the 'great walls' - the largest structures observed in the universe is suggested. Although the basis of the model is the Zel'dovich approximation it has been used in a new way very different from the previous studies. Instead of traditional approach that evaluates the nonlinear density field it has been utilized for identification of the regions in Lagrangian space that after the mapping to real or redshift space (depending on the kind of structure is studied) end up in the regions where shell-crossing occurs. The set of these regions in Lagrangian space form the progenitor of the structure and after the mapping it determines the pattern of the structure in real or redshift space. The particle trajectories have crossed in such regions and the mapping is no longer unique there. The progenitor after mapping makes only one stream in the multi-stream flow regions therefore it does not comprise all the mass. Nevertheless, it approximately retains the shape of the structure. The progenitor of the structure in real space is determined by the linear density field along with two non-Gaussian fields derived from the initial potential. Its shape in Eulerian space is also affected by the displacement field. The progenitor of the structure in redshift space also depends on these fields but in addition it is strongly affected by two anisotropic fields that determine the pattern of great walls as well as their huge sizes. All the fields used in the mappings are derived from the linear potential smoothed at the current scale of nonlinearity which is R nl = 2.7 h −1 Mpc for the adopted parameters of the ΛCDM universe normalized to σ 8 = 0.8. The model predicts the existence of walls with sizes significantly greater than 500 h −1 Mpc that may be found in sufficiently large redshift surveys

    This study is about a questionnaire survey of delegates attending the chronic pancreatitis symposium at the 2016 meeting of the Pancreatic Society of Great Britain and Ireland and seeks a multidisciplinary "snapshot" overview of practice. A questionnaire was developed with multidisciplinary input. Questions on access to specialist care, methods of diagnosis and treatment including specific scenarios were incorporated. Eighty-three (66%) of 125 delegates effectively participated in this survey. Twenty-four (29%) had neither a chronic pancreatitis MDT in their hospital nor a chronic pancreatitis referral MDT. Most frequently utilised diagnostic modalities were CT, MR and EUS with no respondents utilising duodenal intubation tests. Initial treatment was provided through non-opiate analgesia by 69 (93%), through the use of opiates by 56 (76%) and through the use of co-analgesics by 49 (66%). Fifty two (68%) routinely referred patients with alcohol-related disease for counselling. Preferred treatment for large duct disease without mass was endoscopic therapy. In older patients with a mass, pancreaticoduodenectomy was preferred. This is a small study likely to be skewed by sampling bias but is thought to be the first multidisciplinary survey of the management of chronic pancreatitis in the United Kingdom and Ireland. The results show a need for comprehensive access to specialist pancreatitis MDT care and there remains substantial variation in management. © 2018 S. Karger AG, Basel.

    2016-01-01

    The paper is devoted to one of the most important and, at the same time, relatively unexplored phases in the history of Russian science and technology. The Great War coincided with the beginning of a heyday in science, engineering education, and technology in Russia. It was precisely the time in which Russia's era of "Big Science" was emer- ging. Many Russian and Soviet technical projects and scientific schools were rooted in the time of the Great War. The "engineerization" of science and a "physical-technical" way of thinking had already begun before the war. But it was precisely the war which encouraged a large proportion of the Russian academic community to take part in industrial projects. Academics also played a significant role in developing concepts and implementing strategic plans during the Great War. This article also discusses how the organization of science and the academic community was transformed during, and after, the Great War. And it looks at the impact that war had on Russia's participation in the international scientific community.

    2016-01-01

    The social safety net responded in significant and favorable ways during the Great Recession. Aggregate per capita expenditures grew significantly, with particularly strong growth in the SNAP, EITC, UI, and Medicaid programs. Distributionally, the increase in transfers was widely shared across demographic groups, including families with and without children, single-parent and two-parent families. Transfers grew as well among families with more employed members and with fewer employed members. However, the increase in transfer amounts was not strongly progressive across income classes within the low-income population, increasingly slightly more for those just below the poverty line and those just above it, compared to those at the bottom of the income distribution. This is mainly the result of the EITC program, which provides greater benefits to those with higher family earnings. The expansions of SNAP and UI benefitted those at the bottom of the income distribution to a greater extent. PMID:27065356

    Cardiovascular injuries after trauma present with high mortality. The aim of the study was to present our experience in cardiac and great vessel injuries after chest trauma. During the 10-year period, 104 patients with cardiac (n=94) and great vessel (n=10) injuries presented to our hospital. The demographic data, mechanism of injury, location of injury, other associated injuries, timing of surgical intervention, surgical approach, and clinical outcome were reviewed. Eighty-eight (84.6%) males presented after chest trauma. The mean age of the patients was 32.5±8.2 years (range: 12-76). Penetrating injuries (62.5%) were the most common cause of trauma. Computed tomography was performed in most cases and echocardiography was used in some stable cases. Cardiac injuries mostly included the right ventricle (58.5%). Great vessel injuries involved the subclavian vein in 6, innominate vein in 1, vena cava in 1, and descending aorta in 2 patients. Early operations after admission to the emergency were performed in 75.9% of the patients. Thoracotomy was performed in 89.5% of the patients. Operative mortality was significantly high in penetrating injuries (p=0.01). Clinicians should suspect cardiac and great vessel trauma in every patient presenting to the emergency unit after chest trauma. Computed tomography and echocardiography are beneficial in the management of chest trauma. Operative timing depends on hemodynamic status, and a multidisciplinary team approach improves the patient's prognosis.

  14. Practice Location Characteristics of Non-Traditional Dental Practices.

    Solomon, Eric S; Jones, Daniel L

    2016-04-01

    Current and future dental school graduates are increasingly likely to choose a non-traditional dental practice-a group practice managed by a dental service organization or a corporate practice with employed dentists-for their initial practice experience. In addition, the growth of non-traditional practices, which are located primarily in major urban areas, could accelerate the movement of dentists to those areas and contribute to geographic disparities in the distribution of dental services. To help the profession understand the implications of these developments, the aim of this study was to compare the location characteristics of non-traditional practices and traditional dental practices. After identifying non-traditional practices across the United States, the authors located those practices and traditional dental practices geographically by zip code. Non-traditional dental practices were found to represent about 3.1% of all dental practices, but they had a greater impact on the marketplace with almost twice the average number of staff and annual revenue. Virtually all non-traditional dental practices were located in zip codes that also had a traditional dental practice. Zip codes with non-traditional practices had significant differences from zip codes with only a traditional dental practice: the populations in areas with non-traditional practices had higher income levels and higher education and were slightly younger and proportionally more Hispanic; those practices also had a much higher likelihood of being located in a major metropolitan area. Dental educators and leaders need to understand the impact of these trends in the practice environment in order to both prepare graduates for practice and make decisions about planning for the workforce of the future.

    2016-06-01

    This paper presents a complete overview of the scientific, professional and social activity of a great Polish pathologist, Witold Nowicki (1878-1941), from mainly Polish-written, original sources with a major impact on mostly his own publications. The biographical commemoration of this eminent professor is not only due to the fact that he provided a profound microscopic characterization of pneumatosis cystoides in 1909 and 1924. Nowicki greatly influenced the development of anatomical pathology in Poland, having authored over 82 publications, with special reference to tuberculosis, lung cancer, sarcomatous carcinomas, scleroma and others. However, the first of all his merits for the readership of Polish pathologists was his textbook titled Anatomical Pathology, which was a basic pathology manual in pre-war Poland. Witold Nowicki - as the head of the academic pathological anatomy department and former dean of the medical faculty - was shot with other professors by Nazi Germans in the Wuleckie hills in Lvov during World War Two. Professor Nowicki was described as being "small in size but great in spirit" by one of his associates, and remains an outstanding example of a meticulous pathologist, a patient tutor and a great social activist to follow.

  16. The Great California ShakeOut: Science-Based Preparedness Advocacy

    2009-12-01

    The Great Southern California ShakeOut in November 2008 was the largest earthquake drill in U.S. history, involving over 5 million southern Californians through a broad-based outreach program, media partnerships, and public advocacy by hundreds of partners. The basis of the drill was a comprehensive scenario for a magnitude 7.8 earthquake on the southern San Andreas fault, which would cause broad devastation. In early 2009 the decision was made to hold the drill statewide on the third Thursday of October each year (October 15 in 2009). Results of the 2008 and 2009 drills will be shared in this session. In addition, prospects of early warning systems will be described, that will one day provide the needed seconds before strong shaking arrives in which critical systems and be shut down, and people can do what they've been practicing in the ShakeOut drills: drop, cover, and hold on. A key aspect of the ShakeOut is the integration of a comprehensive earthquake scenario (incorporating earth science, engineering, policy, economics, public health, and other disciplines) and the lessons learned from decades of social science research about why people get prepared. The result is a “teachable moment” on par with having an actual earthquake (often followed by increased interest in getting ready for earthquakes). ShakeOut creates the sense of urgency that is needed for people, organizations, and communities to get prepared, to practice what to do to be safe, and to learn what plans need to be improved.

  17. Skill-specificity of language practice and transferability of language skills: The case of listening and speaking

    Full Text Available The study of skill acquisition is of great importance in cognitive psychology. One aspect of skill acquisition research is whether practice in SLA is skill-specific or not. To date, research done has not led to either unanimous rejection or acceptance of the theory. This article is an attempt to examine this question in an EFL context where L2 learners have limited or no access to target language data outside the classroom. More specifically, it tries to see whether listening and speaking in an EFL context necessitate their own specific practice or not. Based on a post-test only design, 16 male, beginner Iranian EFL learners received input-based instruction for three months. When the instruction was over, both listening and speaking performances of the subjects were assessed. The result showed that the subjects had significantly improved their listening ability while their speaking ability had little or no improvement, indicating that different language skills in EFL contexts need specific practice. The findings not only confirm the skill-specificity of language practice, but also rejects VanPatten’s seminal claim that comprehension practice is enough to bring about development, not only in comprehension but also in production.

  18. OF THE GREAT TEMPLE OF BEL

    2017-02-01

    Full Text Available The Great Temple of Bel in Palmyra was a unique edifice which had blended the well established lines of Greco-Roman architecture with the art and taste of the Orient. With the gilded bronze capitals of its 41 Corinthian columns it was the product of enormous effort and budget. It was the gem of a remarkable epoch of wealthy Palmyra and mighty Roma. With its splendidly decorated adyta ceilings it became a source of inspiration and imagination for Western architecture and decorative arts. While continuing to captivate the World, it was leveled and vanished as a grim result of conflict based vandalism. The aim of this work is to piece together this, the most eloquent and stupendous monument of the Roman East, from its ruins and reconstruct it as it was once extant. Its loss is irreplacable, but its photo-realistic reconstruction can offer some solace by waking the memories of the great temple as in the past. The lost reality of the Great Temple of Bel is revived here by digitally constructing its “ghost images".

    Guangshigou uranium deposit is one of the typical granite-pegmatite uranium deposits in China, the ore-body are located in the density zone of the outside contact zone of granite pluton. To distinguish the ore-bearing and Non-ore-bearing pegmatite is one of the most practices and have great significance for the effect of mineral exploration. Based on the field investigation and former research results, contrast research on the characteristics of the pegmatite on petrology, geophysical, geochemistry and stable isotopes have been carried out. It is pointed out that the ore-bearing pegmatite differ from the non-ore-bearing one from macro-and-micro-view in Guangshigou Uranium deposits, the main characteristics are summarized; the macro-and-micro signs are established, the genetic difference between the ore-bearing and non-ore-bearing pegmatite are discussed primarily. The achievements would be helpful for prospecting and researching of this type uranium deposits in China. (authors)

  20. Transposition of the great arteries - a phenotype associated with 16p11.2 duplications?

    2017-12-26

    Genetic analyses of patients with transposition of the great arteries have identified rare copy number variations, suggesting that they may be significant to the aetiology of the disease. This paper reports the identification of a 16p11.2 microduplication, a variation that has yet to be reported in association with transposition of the great arteries. The 16p11.2 microduplication is associated with autism spectrum disorder and developmental delay, but with highly variable phenotypic effects. Autism and attention deficit disorders are observed more frequently in children with congenital heart disease than in the general population. Neonatal surgery is proposed as a risk factor, but as yet unidentified genetic abnormalities should also be taken into account. Thus, congenital heart abnormalities may constitute a part of the phenotypic spectrum associated with duplications at 16p11.2. We suggest chromosomal microarray be considered part of the diagnostic work-up in patients with transposition of the great arteries.

    Herring gulls (Larus argentatus) bioaccumulate mercury (Hg) but it is unknown whether they are exposed at levels of neurological concern. Here we studied brain tissues from gulls at five Great Lakes colonies and one non-Great Lakes colony during spring of 2001 and 2003. Total brain Hg concentrations ranged from 0.14 to 2.0 {mu}g/g (dry weight) with a mean of 0.54 {mu}g/g. Gulls from Scotch Bonnet Island, on the easternmost edge of the Great Lakes, had significantly higher brain Hg than other colonies. No association was found between brain Hg concentration and [3H]-ligand binding to neurochemical receptors (N-methyl-D-aspartate, muscarinic cholinergic, nicotinic cholinergic) or nicotinic receptor {alpha}-7 relative mRNA expression as previously documented in other wildlife. In conclusion, spatial trends in Hg contamination exist in herring gulls across the Great Lakes basin, and herring gulls accumulate brain Hg but not at levels associated with sub-clinical neurochemical alterations. - Spatial trends in brain mercury exist in herring gulls across the Laurentian Great Lakes though levels are not associated with neurochemical biomarkers.

    2006-09-01

    There is a growing trend in Great Britain (GB) for pharmacists to work as self-employed "locums" rather than as permanent employees. Despite this trend, little is known about their work patterns or why they choose to pursue nonstandard forms of work. The overall aim of the study was to explore why locums choose self-employment over a permanent contract and to explore a number of issues commonly associated with nonstandard working, such as marginalization and job satisfaction. A qualitative interview study was undertaken. In-depth telephone interviews were conducted with 34 locum pharmacists randomly selected from the GB register of pharmacists. Locums from a range of age groups, different sectors of practice, and with different work patterns were selected to ensure that a wide range of experiences and views were covered. The need or desire for flexibility was the overriding factor for choosing to work as a locum. A wide range and variety of individual personal circumstances were important drivers, but a desire for work-life balance was fundamental to many. A variety of work patterns were found, ranging from those with more ad hoc working arrangements to those who worked in the same store on a regular basis. Avoiding stress, paperwork, and nonprofessional duties were among reasons for choosing to locum. Disadvantages associated with being a locum included being viewed and treated negatively by peers, and having fewer opportunities for training. No conclusive evidence could be found for locums being marginalized, except for the training issues for some pharmacists. The findings do suggest some cause for concern, with some locums selecting places to work on the basis of attitudes not congruent with socially inclusive approaches to public health care. The locum workforce is far from homogenous or uniform. Freelance working of this kind has advantages for the individual: freedom and independence. But there may be risks for the profession if nonstandard work practices

    Land use change has impacts upon many natural processes, and is one of the key measures of anthropogenic disturbance on ecosystems. Agricultural land covers 70% of Great Britain's (GB) land surface and annually undergoes disturbance and change through farming practices such as crop rotation, ploughing and the planting and subsequent logging of forestry. It is important to quantify how much of GB's agricultural land undergoes such changes and what those changes are at an annual temporal resolu...

    Evaporation is an important yet poorly constrained component of the water budget of the Laurentian Great Lakes, but is known historically to have a significant impact on regional climate, including enhanced humidity and downwind lake effect precipitation. Sparse over lake climate monitoring continues to limit ability to quantify bulk lake evaporation and precipitation rates by physical measurements, impeded by logistical difficulties and costs of instrumenting large areas of open water (10{sup 3}-10{sup 5} km2). Measurements of stable isotopes of oxygen and hydrogen in water samples of precipitation and surface waters within the great lakes basin are used to better understand the controls on the region's water cycle. A stable isotope mass balance approach to calculate long term evaporation as a proportion of input to each lake is discussed. The approach capitalizes on the well understood systematic isotopic separation of an evaporating water body, but includes added considerations for internal recycling of evaporated moisture in the overlying atmosphere that should be incorporated for surface waters sufficiently large to significantly influence surrounding climate.

  9. The emerging role of large eddy simulation in industrial practice: challenges and opportunities.

    2009-07-28

    That class of methods for treating turbulence gathered under the banner of large eddy simulation is poised to enter mainstream engineering practice. There is a growing body of evidence that such methods offer a significant stretch in industrial capability over solely Reynolds-averaged Navier-Stokes (RANS)-based modelling. A key enabling development will be the adaptation of innovative processor architectures, resulting from the huge investment in the gaming industry, to engineering analysis. This promises to reduce the computational burden to practicable levels. However, there are many lessons to be learned from the history of the past three decades. These lessons should be analysed in order to inform, if not modulate, the unfolding of this next cycle in the development of industrial modelling capability. This provides the theme for this paper, which is written very much from the standpoint of the informed practitioner rather than the innovator; someone with a strong motivation to improve significantly the competence with which industrial turbulent flows are treated. It is asserted that the reliable deployment of the methodology in the industrial context will prove to be a knowledge-based discipline, as was the case with RANS-based modelling, if not more so. The community at large should collectively make great efforts to put in place that knowledge base from which best practice advice can be derived at the very start of this cycle of advancement and continue to enrich it as the cycle progresses.

    In developed countries, changes in agriculture practices have greatly accelerated the degradation of the landscape and the functioning of adjacent aquatic ecosystems. Such alteration can in turn impair the services provided by aquatic ecosystems, namely the decomposition of organic matter, a key process in most small streams. To study this alteration, we recorded three measures of heterotrophic activity corresponding to microbial hydrolasic activity (FDA hydrolysis) and leaf litter breakdown rates with (k{sub c}) and without invertebrates (k{sub f}) along a gradient of contrasted agricultural pressures. Hydrolasic activity and k{sub f} reflect local/microhabitat conditions (i.e. nutrient concentrations and organic matter content of the sediment) but not land use while k{sub c} reflects land-use conditions. k{sub c}, which is positively correlated with the biomass of Gammaridae, significantly decreased with increasing agricultural pressure, contrary to the taxonomic richness and biomass of Trichoptera and Plecoptera. Gammaridae may thus be considered a key species for organic matter recycling in agriculture-impacted streams. - This study highlights the consequences of intensive agricultural practices on heterotrophic processes in streams along a strong gradient of perturbation.

    Recent advances in microsurgery, imaging, and transplantation have led to significant refinements in autologous reconstructive options; however, the morbidity of donor sites remains. This would be eliminated by successful clinical translation of tissue-engineered solutions into surgical practice. Plastic surgeons are uniquely placed to be intrinsically involved in the research and development of laboratory engineered tissues and their subsequent use. In this article, we present an overview of the field of tissue engineering, with the practicing plastic surgeon in mind. The Medical Research Council states that regenerative medicine and tissue engineering “holds the promise of revolutionizing patient care in the twenty-first century.” The UK government highlighted regenerative medicine as one of the key eight great technologies in their industrial strategy worthy of significant investment. The long-term aim of successful biomanufacture to repair composite defects depends on interdisciplinary collaboration between cell biologists, material scientists, engineers, and associated medical specialties; however currently, there is a current lack of coordination in the field as a whole. Barriers to translation are deep rooted at the basic science level, manifested by a lack of consensus on the ideal cell source, scaffold, molecular cues, and environment and manufacturing strategy. There is also insufficient understanding of the long-term safety and durability of tissue-engineered constructs. This review aims to highlight that individualized approaches to the field are not adequate, and research collaboratives will be essential to bring together differing areas of expertise to expedite future clinical translation. The use of tissue engineering in reconstructive surgery would result in a paradigm shift but it is important to maintain realistic expectations. It is generally accepted that it takes 20–30 years from the start of basic science research to clinical utility

    2014-01-01

    Full Text Available Legal position of non-marital children according to 19th century Serbian legislature and judicial practice is examined in this paper. Provisions and court decisions on personal rights, property rights and rights of succession of illegitimate children are presented and critically analyzed. Children born out of wedlock were not equal to children born in lawful marriage. Therefore, significance of legalization of illegitimate children regarding improvement of their legal status is accentuated. As non-marital relationships were condemned in patriarchal Serbian 19th century society, illegitimate children were considered a product of sin and family disgrace. Hence, legislative and judicial attempts to protect their interests and improve their legal position are emphasized in this paper. Beside legalization, adoption was also the way to better position of illegitimate children in great extent, as adopted child was granted the status of a child born in lawful marriage. That is a reason why judicial practice concerning adoption, widespread in 19th century Serbia, is scrutinized and critically analyzed in the article.

  18. The Great Kanto earthquake and F. Scott Fitzgerald

    Kawakatsu, Hitoshi; Bina, Craig R.

    How many recall the following striking sentence from The Great Gatsby by F. Scott Fitzgerald, which appears on the second page of the novel, where Fitzgerald first introduces Gatsby? “If personality is an unbroken series of successful gestures, then there was something gorgeous about him, some heightened sensitivity to the promises of life, as if he were related to one of those intricate machines that register earthquakes ten thousand miles away.”This line may have failed to focus our attention when we first read the book in our younger days. Now, however, as a Japanese seismologist and an American geophysicist (and student of Japanese culture), we would be greatly remiss for failing to take greater note of this statement. Indeed, as The Great Gatsby was published in 1925, it occurred to us that the earthquake Fitzgerald might have been thinking of was the Great Kanto earthquake, which occurred on September 1, 1923 and devastated the Tokyo metropolitan area.

  19. Standardizing the practice of human reliability analysis

    International Nuclear Information System (INIS)

    Hallbert, B.P.

    1993-01-01

    The practice of human reliability analysis (HRA) within the nuclear industry varies greatly in terms of posited mechanisms that shape human performance, methods of characterizing and analytically modeling human behavior, and the techniques that are employed to estimate the frequency with which human error occurs. This variation has been a source of contention among HRA practitioners regarding the validity of results obtained from different HRA methods. It has also resulted in attempts to develop standard methods and procedures for conducting HRAs. For many of the same reasons, the practice of HRA has not been standardized or has been standardized only to the extent that individual analysts have developed heuristics and consistent approaches in their practice of HRA. From the standpoint of consumers and regulators, this has resulted in a lack of clear acceptance criteria for the assumptions, modeling, and quantification of human errors in probabilistic risk assessments

  20. Practice of Environmentally Significant Behaviours in Rural China: From Being Motivated by Economic Gains to Being Motivated by Environmental Considerations.

    A continuous and increasing crisis that present-day China is facing is environmental degradation. The cultivation of citizens who have environmentally friendly behaviours has been deemed as a fundamental way to solve environmental crises. However, the main focus of environmentalism studies has been urban residents, whereas rare research attention was put on rural Chinese. This paper focuses on environmentally significant behaviours in rural China and aims to clarify the practice of five environmentally significant behaviours and two motivations underlying these behaviours. In total, 508 rural residents in 51 villages of Ningyang county were interviewed. Analytical results derived from survey data showed that environmentally significant behaviours are widely conducted in rural areas. However, these behaviours are mainly motivated by economic gains rather than environmental considerations. In addition, based on the norm-activation theory and considering the influences of demographic factors, the formation of environmentally motivated behaviours were quantitatively analysed. Analytical results indicated that the more people worried about environmental deterioration, the more likely they were to form environmentally motivated behaviours, and people who ascribe the most important environmental responsibility to the government are less likely to form environmentally motivated behaviours. Increasing people's anxiety towards the environment, decreasing people's dependency on the government in protecting the environment, and using females, the elderly, and people with low income and education levels as the main targets of environmental education are suggested to promote environmentally motivated behaviours in rural China.

Increasing people’s anxiety towards the environment, decreasing people’s dependency on the government in protecting the environment, and using females, the elderly, and people with low income and education levels as the main targets of environmental education are suggested to promote environmentally motivated behaviours in rural China.

    Staphylococcus aureus is a pathogen of major concern. The emergence of methicillin-resistant S. aureus (MRSA) has increasingly complicated the therapeutic approach of hospital-acquired infections. Surveillance of MRSA and control measures must be implemented in different healthcare settings, including screening programs for carriers. Our first aim was to determine the prevalence of methicillin-susceptible S. aureus (MSSA) and MRSA nasal carriage in medical students from the Clínico San Carlos Hospital (Madrid). As the MRSA carrier rate in healthcare workers is higher than in the general population, we hypothesised that carrier rate could be increased during their clinical practice in their last three years. We performed an epidemiologic al study of the prevalence of S. aureus colonisation among a group of medical students, who were sampled in 2008 in their third-year, and in 2012 when this class was in its sixth year. We have found a significant increase in MSSA carriage, from 27% to 46%. There were no MRSA colonisations in the third-year, but one was found in the sixth-year group. The large majority of strains (89%) of strains were resistant to penicillin, and 27% to erythromycin and clindamycin. As 19 coagulase-negative Staphylococcus MR were also identified, a horizontal transfer of genes, such as mecA gene to S. aureus, could have occurred. Medical students are both, at risk for acquiring, and a potential source of nosocomial pathogens, mainly MSSA. Therefore, they should take special care for hygienic precautions, such as frequent and proper hand washing, while working in the hospital. Copyright © 2012 Elsevier España, S.L.

    Traffic accidents are the second leading cause of death among adolescents and young adults in Chile. However, few studies have examined this behavior among this age group. Parental practices have a great influence on risk behaviors in adolescents, such as substance use, sexuality and violence, among others. Specifically, we propose that these practices will influence pedestrian risk behaviors among adolescents. To study the role of parental practices such as mother and father support, and behavioral control (monitoring and presence of rules) in pedestrian risk behaviors of teenagers. A sample of 470 adolescents attending schools in the Metropolitan Region of Santiago, Chile were studied. They answered a self-administered questionnaire in which they were asked about parental practices and pedestrian risk behaviors. Analyses were performed using descriptive and inferential statistics, using multiple regression. Paternal support and the presence of rules were protective factors for pedestrian risky behaviors. However, maternal support or monitoring did not influence these behaviors. Parental practices influence pedestrian behaviors of teenagers. The study provides further evidence for the importance of these practices in the development of behavioral self-regulation.

    Full Text Available The purpose of this paper is to present a basic compendium of how companies can integrate social responsibility into their strategies. The paper analyzes and synthesizes ideas and proposals based on the literature review from different fields. It proposes a practical approach that does not highlight the differences but the positive and mutual synergy of social responsibility with firm’s strategy. There are many practical proposals in the literature and a lot of successful examples from business practice that show how organizations can or have made the implementation of social responsibility into their strategy to work efficiently, but their strategic, social, and environmental importance differs and is limited by many factors. The paper presents different means of connecting social responsibility with organizational strategy to make it work, which can be useful for practitioners, students, and wider public. The paper adds the praxiological or practical perspective to deal with a small but persisting organizational problem and a great social expectation, how to link efficiently social responsibility with organizational strategy into one coherent stream of purposes.

  8. Individual and population-level impacts of an emerging poxvirus disease in a wild population of great tits.

    Directory of Open Access Journals (Sweden)

    Shelly Lachish

    Full Text Available Emerging infectious diseases of wildlife can have severe effects on host populations and constitute a pressing problem for biodiversity conservation. Paridae pox is an unusually severe form of avipoxvirus infection that has recently been identified as an emerging infectious disease particularly affecting an abundant songbird, the great tit (Parus major, in Great Britain. In this study, we study the invasion and establishment of Paridae pox in a long-term monitored population of wild great tits to (i quantify the impact of this novel pathogen on host fitness and (ii determine the potential threat it poses to population persistence. We show that Paridae pox significantly reduces the reproductive output of great tits by reducing the ability of parents to fledge young successfully and rear those young to independence. Our results also suggested that pathogen transmission from diseased parents to their offspring was possible, and that disease entails severe mortality costs for affected chicks. Application of multistate mark-recapture modelling showed that Paridae pox causes significant reductions to host survival, with particularly large effects observed for juvenile survival. Using an age-structured population model, we demonstrate that Paridae pox has the potential to reduce population growth rate, primarily through negative impacts on host survival rates. However, at currently observed prevalence, significant disease-induced population decline seems unlikely, although pox prevalence may be underestimated if capture probability of diseased individuals is low. Despite this, because pox-affected model populations exhibited lower average growth rates, this emerging infectious disease has the potential to reduce the resilience of populations to other environmental factors that reduce population size.

    2017-12-01

    Full Text Available The major goal of the paper was to develop a theoretical framework that conceptualizes the indirect impact on human resource management practice on knowledge sharing in the organization. In the current competitive environment, the ability to use knowledge assets and to continuously renovate it is required for organizational success. Therefore, the field of human resource management should dedicate great effort to understanding how to enhance the knowledge flows within the organization. Theoretical indications were provided about HRM practices that influence the quality and quantity of knowledge sharing within an organization. Further, a conceptual model of relations between HRM practices and factors influencing knowledge sharing within an organization was introduced. It is supposed that HRM practices have direct impacts on personality traits of employees, organizational culture, characteristics of managers, and instruments used for knowledge sharing. Subsequently, these factors have direct effects on the perceived intensity of knowledge sharing. The paper offers 12 testable propositions for the indirect relation between HRM practices and knowledge sharing in the organization. The suggested model could assist future research to examine the influence of HRM practices upon managing knowledge is a more complex way. Via a theoretical contribution to the debate on the influence on HRM practices upon managing knowledge, the study contributes to further research development in this field.

    Mark D. Cohen

    2016-07-01

    Full Text Available Abstract Mercury contamination in the Great Lakes continues to have important public health and wildlife ecotoxicology impacts, and atmospheric deposition is a significant ongoing loading pathway. The objective of this study was to estimate the amount and source-attribution for atmospheric mercury deposition to each lake, information needed to prioritize amelioration efforts. A new global, Eulerian version of the HYSPLIT-Hg model was used to simulate the 2005 global atmospheric transport and deposition of mercury to the Great Lakes. In addition to the base case, 10 alternative model configurations were used to examine sensitivity to uncertainties in atmospheric mercury chemistry and surface exchange. A novel atmospheric lifetime analysis was used to characterize fate and transport processes within the model. Model-estimated wet deposition and atmospheric concentrations of gaseous elemental mercury (Hg(0 were generally within ∼10% of measurements in the Great Lakes region. The model overestimated non-Hg(0 concentrations by a factor of 2–3, similar to other modeling studies. Potential reasons for this disagreement include model inaccuracies, differences in atmospheric Hg fractions being compared, and the measurements being biased low. Lake Erie, downwind of significant local/regional emissions sources, was estimated by the model to be the most impacted by direct anthropogenic emissions (58% of the base case total deposition, while Lake Superior, with the fewest upwind local/regional sources, was the least impacted (27%. The U.S. was the largest national contributor, followed by China, contributing 25% and 6%, respectively, on average, for the Great Lakes. The contribution of U.S. direct anthropogenic emissions to total mercury deposition varied between 46% for the base case (with a range of 24–51% over all model configurations for Lake Erie and 11% (range 6–13% for Lake Superior. These results illustrate the importance of atmospheric

  16. Training directionally selective motion pathways can significantly improve reading efficiency

    Lawton, Teri

    2004-06-01

    This study examined whether perceptual learning at early levels of visual processing would facilitate learning at higher levels of processing. This was examined by determining whether training the motion pathways by practicing leftright movement discrimination, as found previously, would improve the reading skills of inefficient readers significantly more than another computer game, a word discrimination game, or the reading program offered by the school. This controlled validation study found that practicing left-right movement discrimination 5-10 minutes twice a week (rapidly) for 15 weeks doubled reading fluency, and significantly improved all reading skills by more than one grade level, whereas inefficient readers in the control groups barely improved on these reading skills. In contrast to previous studies of perceptual learning, these experiments show that perceptual learning of direction discrimination significantly improved reading skills determined at higher levels of cognitive processing, thereby being generalized to a new task. The deficits in reading performance and attentional focus experienced by the person who struggles when reading are suggested to result from an information overload, resulting from timing deficits in the direction-selectivity network proposed by Russell De Valois et al. (2000), that following practice on direction discrimination goes away. This study found that practicing direction discrimination rapidly transitions the inefficient 7-year-old reader to an efficient reader.

  20. Enamel hypoplasia in deciduous teeth of great apes: do differences in defect prevalence imply differential levels of physiological stress?

    Science.gov (United States)

    Lukacs, J R

    1999-11-01

    This paper presents new data on enamel hypoplasia in the deciduous canine teeth of great apes. The enamel defect under consideration is known as localized hypoplasia of primary canines (LHPC), and is characterized by an area of thin or missing enamel on the labial surface of deciduous canine teeth (Skinner [1986a] Am. J. Phys. Anthropol. 69:59-69). Goals of this study are: 1) to determine if significant differences in the frequency of LHPC occur among three genera of great apes, and 2) to evaluate variation in LHPC prevalence among great apes as evidence of differential physiological stress. Infant and juvenile apes with deciduous teeth were examined at the Cleveland Museum of Natural History (n = 100) and at the Smithsonian Institution, National Museum of Natural History (n = 36). Deciduous teeth were observed under oblique incandescent light, with the naked eye and with a 10x hand lens. Enamel hypoplasia was scored using Federation Dentaire International (FDI)-Defects of Dental Enamel (DDE) standards. Hypoplasias were recorded by drawing defect location and size on a dental chart, and by measuring defect size and location with Helios needlepoint dial calipers. The prevalence of LHPC is reported by genus and sex, using two approaches: 1) the frequency of affected individuals-those having one or more deciduous canine teeth scored positive for LHPC; and 2) the number of canine teeth scored positive for LHPC as a percentage of all canine teeth observed. Variation in defect size and location will be described elsewhere. Localized hypoplasia of primary canine teeth was found in 62.5% of 128 individual apes, and in 45.5% of 398 great ape deciduous canines. As in humans, LHPC is the most common form of enamel hypoplasia in deciduous teeth of great apes, while LEH is rare or absent. The distribution and pattern of expression of LHPC in great apes is similar to that described in humans: side differences are not significant, but mandibular canines exhibit the defect two to

  1. Transgenic Anopheles gambiae expressing an antimalarial peptide suffer no significant fitness cost.

    Directory of Open Access Journals (Sweden)

    Clare C McArthur

    Full Text Available Mosquito-borne diseases present some of the greatest health challenges faced by the world today. In many cases, existing control measures are compromised by insecticide resistance, pathogen tolerance to drugs and the lack of effective vaccines. In light of these difficulties, new genetic tools for disease control programmes, based on the deployment of genetically modified mosquitoes, are seen as having great promise. Transgenic strains may be used to control disease transmission either by suppressing vector populations or by replacing susceptible with refractory genotypes. In practice, the fitness of the transgenic strain relative to natural mosquitoes will be a critical determinant of success. We previously described a transgenic strain of Anopheles gambiae expressing the Vida3 peptide into the female midgut following a blood-meal, which exhibited significant protection against malaria parasites. Here, we investigated the fitness of this strain relative to non-transgenic controls through comparisons of various life history traits. Experiments were designed, as far as possible, to equalize genetic backgrounds and heterogeneity such that fitness comparisons focussed on the presence and expression of the transgene cassette. We also employed reciprocal crosses to identify any fitness disturbance associated with inheritance of the transgene from either the male or female parent. We found no evidence that the presence or expression of the effector transgene or associated fluorescence markers caused any significant fitness cost in relation to larval mortality, pupal sex ratio, fecundity, hatch rate or longevity of blood-fed females. In fact, fecundity was increased in transgenic strains. We did, however, observe some fitness disturbances associated with the route of inheritance of the transgene. Maternal inheritance delayed male pupation whilst paternal inheritance increased adult longevity for both males and unfed females. Overall, in comparison to

    In recent years solvent extraction has been developed to a stage that allows practical application first for the recovery of uranium and later also for winning copper from low-grade acid-soluble ores. By now it has been realized in several plants with great technical and ecomomic success. Solvent extraction includes the following essential operations: leaching, solvent extraction, back extraction of the organically bonded valuable mineral to an acid, aqueous solution and finally separation of the valuable metal from the final acid by precipitation or electrolytic procedures. Upon assessing the cost of the solvent extraction process for the recovery of copper it turns out that from an economic point of view it is significantly superior to the conventional cementation process.

    2002-01-01

    Antifoulant concentrations are generally low in the Great Barrier Reef, although ship grounding sites present a previously unidentified significant source of antifoulant pollutants in the Great Barrier Reef. - Antifoulant concentrations were determined in marine sediments collected from commercial harbours, marinas, mooring locations on mid-shelf continental islands, and outer reef sites in four regions within the Great Barrier Reef World Heritage Area in 1999. Highest copper concentrations were present in sediments collected from commercial harbour sampling sites (28-233 μg Cu g -1 dry wt.). In contrast, copper concentrations in sediments collected from boat mooring sites on mid-shelf continental islands and outer reef sites were at background concentrations (i.e. -1 dry wt.). Butyltin was only detectable in four of the 42 sediments sampled for analysis, and was only present in sediments collected from commercial harbours (18-1275 ng Sn g -1 dry wt.) and from marinas (4-5 ng Sn g -1 dry wt.). The detection of tributyltin at marina sites implies that this antifoulant may continue to be used illegally on the hulls of smaller recreational vessels. Sediment samples were also collected opportunistically from the site of a 22,000 t cargo ship grounding in May 1999 at Heath Reef, in the far northern Great Barrier Reef. Butyltin concentrations were grossly elevated (660-340,000 ng Sn g -1 dry wt.) at the grounding site. The impact of residual antifoulants at large ship grounding sites should be recognised as a significant, long-term environmental problem unless antfoulant clean-up strategies are undertaken

    2017-01-01

    The United States Northern Great Plains (NGP) has a high potential for landscape-scale conservation, but this grassland landscape is threatened by encroachment of woody species. We surveyed NGP land managers to identify patterns in, and illustrate a broad range of, individual managers' perceptions on (1) the threat of woody encroachment to grasslands they manage, and (2) what management practices they use that may influence woody encroachment in this region. In the 34 surveys returned, which came from predominantly public lands in the study area, 79% of responses reported moderate or substantial woody encroachment. Eastern redcedar (Juniperus virginiana) and Rocky Mountain juniper (Juniperus scopulorum) were the most problematic encroachers. Thirty-one survey respondents said that prescribed fire was used on the lands they manage, and 64% of these responses reported that controlling woody encroachment was a fire management objective. However, only 18% of survey respondents using prescribed fire were achieving their desired fire return interval. Most respondents reported using mechanical and/or chemical methods to control woody species. In contrast to evidence from the central and southern Great Plains, few survey respondents viewed grazing as affecting encroachment. Although the NGP public land managers we surveyed clearly recognize woody encroachment as a problem and are taking steps to address it, many feel that the rate of their management is not keeping pace with the rate of encroachment. Developing strategies for effective woody plant control in a variety of NGP management contexts requires filling ecological science gaps and overcoming societal barriers to using prescribed fire.

    Cadmium (Cd) and arsenic (As) accumulation in rice grains is a great threat to its productivity, grain quality, and thus human health. Pot and field studies were carried out to unravel the effect of different water management practices (aerobic, aerobic-flooded, and flooded) on Cd and As accumulation in rice grains of two different varieties. In pot experiment, Cd or As was also added into the soil as treatment. Pots without Cd or As addition were maintained as control. Results indicated that water management practices significantly influenced the Cd and As concentration in rice grains and aerobic cultivation of rice furnished less As concentration in its grains. Nonetheless, Cd concentration in this treatment was higher than the grains of flooded rice. Likewise, in field study, aerobic and flooded rice cultivation recorded higher Cd and As concentration, respectively. However, growing of rice in aerobic-flooded conditions decreased the Cd concentration by 9.38 times on average basis as compared to aerobic rice. Furthermore, this treatment showed 28% less As concentration than that recorded in flooded rice cultivation. The results suggested that aerobic-flooded cultivation may be a promising strategy to reduce the Cd and As accumulations in rice grains simultaneously.

    2016-01-01

    Motor practice in lucid dreams is a form of mental rehearsal where the dreamer can consciously rehearse motor skills in the dream state while being physically asleep. A previous pilot study showed that practice in lucid dreams can improve subsequent performance. This study aimed to replicate those findings with a different task (finger-tapping) and compare the effectiveness of lucid dream practice (LDP) not only to physical but also to mental practice (MP) in wakefulness. An online experiment was completed by 68 participants within four groups: LDP group, MP group, physical practice (PP) group and control (no practice) group. Pre-test was accomplished in the evening, post-test in the next morning, while the practice was done during the night. All three practice groups significantly improved their performance from pre-test to post-test, but no significant improvements were observed for the control group. Subjective sleep quality was not affected by night practice. This study thus corroborates the previous findings that practice in lucid dreams is effective in improving performance. Its effects seem to be similar to actual PP and MP in wakefulness. Future studies should establish reliable techniques for lucid dream induction and verify the effects of LDP in sleep laboratory conditions.

  12. Environmental lead: a survey of its possible physiological significance

    Energy Technology Data Exchange (ETDEWEB)

    Warren, H.V.

    1974-01-01

    Sources of environmental lead are discussed in a survey of diseases of the nervous system. Only 5-10 percent of the Pb ingested in food and water is absorbed, while 40-50 percent of the Pb present in inhaled air is absorbed. Air, dust, and leaded gasoline are among the sources of Pb. Normal rural air in the United States may contain 0.05 micrograms of Pb/cu m, while 0.3-2.5 may be representative of general urban areas. An urban dweller can inhale daily 60-120 micrograms of Pb, but it is not known whether 25 or 50 percent of this Pb is absorbed. Values from 0.5 to 6 percent Pb in dust are common in many large cities in Great Britain, Canada, and the United States. Evidence exists in the United States and Great Britain to show the significance of atmosphere and vegetative pollution by tetraethyl Pb discharged in the exhaust fumes of motor vehicles. It not only is a major contribution to the Pb occurring in urban air and dust but also adds indirectly, and significantly, to the Pb content of the food grown in some localities. Many diseases of the nervous system as multiple sclerosis, swayback, kuru, motor neurone disease, and amyotrophic lateral sclerosis frequently have an unexplained association with Pb or mercury.

    Three great physical revolutions are studied here: the theory of relativity (general and restricted); the quantum mechanics (and its different interpretations); the theory of the determinist chaos (its pre-history as its applications). These three theories contribute to modify the answers that it is possible to bring to great metaphysical questions and to give a hint of a new philosophical landscape. (N.C.)

    The amount of time that people, especially young people, spend on communicative activities in social media is rapidly increasing. We are facing new arenas with great potential for learning in general and for language learning in particular, but their impact on learning is not yet acknowledged as such in educational practice (e.g., Conole, 2010;…

  18. Estimation of the ancestral effective population sizes of African great apes under different selection regimes.

    2014-08-01

    Reliable estimates of ancestral effective population sizes are necessary to unveil the population-level phenomena that shaped the phylogeny and molecular evolution of the African great apes. Although several methods have previously been applied to infer ancestral effective population sizes, an analysis of the influence of the selective regime on the estimates of ancestral demography has not been thoroughly conducted. In this study, three independent data sets under different selective regimes were used were composed to tackle this issue. The results showed that selection had a significant impact on the estimates of ancestral effective population sizes of the African great apes. The inference of the ancestral demography of African great apes was affected by the selection regime. The effects, however, were not homogeneous along the ancestral populations of great apes. The effective population size of the ancestor of humans and chimpanzees was more impacted by the selection regime when compared to the same parameter in the ancestor of humans, chimpanzees and gorillas. Because the selection regime influenced the estimates of ancestral effective population size, it is reasonable to assume that a portion of the discrepancy found in previous studies that inferred the ancestral effective population size may be attributable to the differential action of selection on the genes sampled.

    2013-01-01

    There is an abundance of data for levels of metals from a range of species, but relatively few long-term time series from the same location. In this paper I examine the levels of arsenic, cadmium, chromium, lead, manganese, mercury and selenium in feathers from fledgling great egrets (Ardea alba) collected at nesting colonies in Barnegat Bay, New Jersey from 1989 to 2011. The primary objectives were to test the null hypotheses that (1) There were no temporal differences in metal levels in feathers of fledgling great egrets, and (2) Great egrets nesting in different areas of Barnegat Bay (New Jersey) did not differ in metal levels. There were significant yearly variations in levels of all heavy metals in feathers of fledgling great egret, but levels decreased significantly from 1989 to 2011 only for lead (1470 ppb to 54.3 ppb), cadmium (277 ppb to 30.5 ppb), and manganese (only since 1996; 2669 ppb to 329 ppb)). Although mercury levels decreased from 2003–2008 (6430 ppb to 1042 ppb), there was no pattern before 2003, and levels increased after 2008 to 2610 ppb in 2011. Lead, cadmium, chromium, manganese and mercury were higher in feathers from great egrets nesting in the northern part of the bay, and selenium was highest in feathers from mid-bay. The lack of a temporal decline in mercury levels in feathers of great egrets is cause for concern, since the high levels in feathers from some years (means as high as 6430 ppb) are in the range associated with adverse effects (5000 ppb for feathers). -- Highlights: ► Metals were monitored in feathers of great egrets from Barnegat Bay, New Jersey. ► Levels of cadmium and lead decreased significantly from 1989–2011. ► Mercury levels in feathers from great egrets did not decline from 1989–2011. ► Metal levels were generally higher in great egrets and black-crowned night heron feathers than in snowy egrets

    2010-01-01

    This review and statistical analysis was conducted to better understand the nature and significance of environmental exposures in the Great Lakes Basin and watershed to a variety of environmental contaminants. These contaminants of interest included current-use pesticides, pharmaceuticals, organic wastewater contaminants, alkylphenol ethoxylates, perfluorinated surfactants, flame retardants, and chlorinated paraffins. The available literature was critically reviewed and used to develop a database containing 19,611 residue values for 326 substances. In many papers, sampling locations were characterized as being downstream from municipal wastewater discharges, receiving waters for industrial facilities, areas susceptible to agricultural or urban contamination, or harbors and ports. To develop an initial assessment of their potential ecological significance, the contamination levels found were compared with currently available regulatory standards, guidelines, or criteria. This review was prepared for the IJC multi-board work group, and served as background material for an expert consultation, held in March, 2009, in which the significance of the contaminants found was discussed. Moreover, the consultation attempted to identify and assess opportunities for strengthening future actions that will protect the Great Lakes. Based on the findings and conclusions of the expert consultation, it is apparent that a wide variety of chemicals of emerging concern have been detected in environmental media (air, water, sediment, biota) from the Great Lakes Basin, although many are present at only trace levels. Although the presence of these contaminants raises concerns in the public and among the scientific community, the findings must be placed in context. Significant scientific interpretation is required to understand the extent to which these chemicals may pose a threat to the ecosystem and to human health. The ability to detect chemicals in environmental media greatly surpasses

    For wind resource assessment projects, it is common practice to use a power-law relationship (U(z) {proportional_to} z{sup {alpha}}) and a fixed shear exponent ({alpha} = 1/7) to extrapolate the observed wind speed from a low measurement level to high turbine hub-heights. However, recent studies using tall-tower observations have found that the annual average shear exponents at several locations over the United States Great Plains (USGP) are significantly higher than 1/7. These findings highlight the critical need for detailed spatio-temporal characterizations of wind shear climatology over the USGP, where numerous large wind farms will be constructed in the foreseeable future. In this paper, a new generation numerical weather prediction model - the Weather Research and Forecasting (WRF) model, a fast and relatively inexpensive alternative to time-consuming and costly tall-tower projects, is utilized to determine whether it can reliably estimate the shear exponent and the magnitude of the directional shear at any arbitrary location over the USGP. Our results indicate that the WRF model qualitatively captures several low-level wind shear characteristics. However, there is definitely room for physics parameterization improvements for the WRF model to reliably represent the lower part of the atmospheric boundary layer. (author)

  7. Practical virtue ethics: healthcare whistleblowing and portable digital technology.

    Bolsin, S; Faunce, T; Oakley, J

    2005-10-01

    Medical school curricula and postgraduate education programmes expend considerable resources teaching medical ethics. Simultaneously, whistleblowers' agitation continues, at great personal cost, to prompt major intrainstitutional and public inquiries that reveal problems with the application of medical ethics at particular clinical "coalfaces". Virtue ethics, emphasising techniques promoting an agent's character and instructing their conscience, has become a significant mode of discourse in modern medical ethics. Healthcare whistleblowers, whose complaints are reasonable, made in good faith, in the public interest, and not vexatious, we argue, are practising those obligations of professional conscience foundational to virtue based medical ethics. Yet, little extant virtue ethics scholarship seriously considers the theoretical foundations of healthcare whistleblowing. The authors examine whether healthcare whistleblowing should be considered central to any medical ethics emphasising professional virtues and conscience. They consider possible causes for the paucity of professional or academic interest in this area and examine the counterinfluence of a continuing historical tradition of guild mentality professionalism that routinely places relationships with colleagues ahead of patient safety.Finally, it is proposed that a virtue based ethos of medical professionalism, exhibiting transparency and sincerity with regard to achieving uniform quality and safety of health care, may be facilitated by introducing a technological imperative using portable computing devices. Their use by trainees, focused on ethical competence, provides the practical face of virtue ethics in medical education and practice. Indeed, it assists in transforming the professional conscience of whistleblowing into a practical, virtue based culture of self reporting and personal development.

  8. Observing Semi-Arid Ecoclimates across Mountain Gradients in the Great Basin, USA

    Strachan, Scotty

    Observation of climate and ecohydrological variables in mountain systems is a necessary (if challenging) endeavor for modern society. Water resources are often intimately tied to mountains, and high elevation environments are frequently home to unique landscapes and biota with limited geographical distributions. This is especially true in the temperate and semi-arid mountains of the western United States, and specifically the Great Basin. Stark contrasts in annual water balance and ecological populations are visible across steep elevational gradients in the region; and yet the bulk of our historical knowledge of climate and related processes comes from lowland observations. Interpolative models that strive to estimate conditions in mountains using existing datasets are often found to be inaccurate, making future projections of mountain climate and ecosystem response suspect. This study details the results of high-resolution topographically-diverse ecohydrological monitoring, and describes the character and seasonality of basic climatic variables such as temperature and precipitation as well as their impact on soil moisture and vegetation during the 2012-2015 drought sequence. Relationships of topography (elevation/aspect) to daily and seasonal temperatures are shown. Tests of the PRISM temperature model are performed at the large watershed scale, revealing magnitudes, modes, and potential sources of bias that could dramatically affect derivative scientific conclusions. A new method of precipitation phase partitioning to detect and quantify frozen precipitation on a sub-daily basis is described. Character of precipitation from sub-daily to annual scales is quantified across all major Great Basin vegetation/elevation zones, and the relationship of elevation to precipitation phase, intensity, and amount is explored. Water-stress responses of Great Basin conifers including Pinus flexilis, Pinus longaeva, and Pinus ponderosa are directly observed, showing potential

  9. Locating the Great Red Spot: Yesterday, Today, and Tomorrow

    The Great Red Spot, a persistent storm in Jupiter's atmosphere, is the most prominent feature of that planet's disk as viewed from Earth. Combined with the fact that Jupiter is a gas giant planet and has no visible surface with discernible landmarks, this means that following the passage of the Great Red Spot is the primary method of observing the planet's rotation. Therefore, it is paramount for any program which generates synthetic images of the planet to accurately place the feature. The U.S. Naval Observatory's "Apparent Disk of a Solar System Object" online web service (http://aa.usno.navy.mil/data/docs/diskmap.php) is such a program. The Great Red Spot's planetary latitude is locked between two of Jupiter's striated atmospheric layers at 22 °S. However, its planetary longitude is not constant; over time it migrates east and west along the atmospheric layer boundary it is trapped within. Observing and recording its longitude is made difficult because Jupiter's atmosphere is subject to differential rotation and the Great Red Spot slowly migrates with respect to the surrounding atmospheric layers. Furthermore, the Great Red Spot does not move at a uniform rate. Currently its relative motion is approximately 0°.051 per day. Since its first recorded observation in 1831, the Great Red Spot has made almost three complete laps around the planet at the 22nd parallel. "Apparent Disk of a Solar System Object" operates over any requested date between 1700 and 2100 A.D. Therefore, our treatment of the Great Red Spot needs to take into account both historical positions and future predicted motion. Based on researching past observations of the spot's position on the disk, we find that its behavior prior to 2009 is best represented by a 10-part piecewise function. Each component of the piecewise function is a 2nd order polynomial. Observations from 2009-present are better fit with a linear function; this function is used for future years by extrapolation. Using these fits

    In Great Britain, several policy measures have been implemented in order to increase energy efficiency and reduce carbon emissions. In the domestic sector, this could, for example, be achieved by improving space heating efficiency and thus decreasing heating expenditure. However, in order to efficiently design and implement such policy measures, a better understanding of the determinants affecting heating expenditure is needed. In this paper we examine the following determinants: socio-economic factors, building characteristics, heating technologies and weather conditions. In contrast to most other studies we use panel data to investigate household demand for heating in Great Britain. Our data sample is the result of an annual set of interviews with more than 5000 households, starting in 1991 and ending in 2005. The sample represents a total of 64,000 observations over the fifteen-year period. Our aim is to derive price and income elasticities both for Britain as a whole and for different types of household. Our results suggest that differences exist between owner-occupied and renter households. These households react differently to changes in income and prices. Our results also imply that a number of socio-economic criteria have a significant influence on heating expenditure, independently of the fuel used for heating. Understanding the impacts of different factors on heating expenditure and impact differences between types of household is helpful in designing target-oriented policy measures. (author)

    National early childhood obesity prevention policies recommend that child-care providers avoid controlling feeding practices (CFP) (eg, pressure-to-eat, food as reward, and praising children for cleaning their plates) with children to prevent unhealthy child eating behaviors and childhood obesity. However, evidence suggests that providers frequently use CFP during mealtimes. Using the Academy of Nutrition and Dietetics (2011) benchmarks for nutrition in child care as a framework, researchers assessed child-care providers' perspectives regarding their use of mealtime CFP with young children (aged 2 to 5 years). Using a qualitative design, individual, face-to-face, semi-structured interviews were conducted with providers until saturation was reached. Providers were selected using maximum variation purposive sampling from varying child-care contexts (Head Start, Child and Adult Care Food Program [CACFP]-funded centers, non-CACFP programs). All providers were employed full-time in Head Start or state-licensed center-based child-care programs, cared for children (aged 2 to 5 years), and were directly responsible for serving meals and snacks. Child-care providers' perspectives regarding CFP. Thematic analysis using NVivo (version 9, 2010, QSR International Pty Ltd) to derive themes. Providers' perspectives showed barriers, motivators, and facilitators regarding their use of mealtime CFP. Providers reported barriers to avoiding CFP such as CFP were effective for encouraging desired behaviors, misconceptions that providers were encouraging but not controlling children's eating, and fear of parents' negative reaction if their child did not eat. Providers who did not practice CFP were motivated to avoid CFP because they were unnecessary for encouraging children to eat, and they resulted in negative child outcomes and obesity. Facilitators as an alternative to CFP included practicing healthful feeding practices such as role modeling, peer modeling, and sensory exploration of

  16. A Dynamical Downscaling study over the Great Lakes Region Using WRF-Lake: Historical Simulation

    2014-12-01

    As the largest group of fresh water bodies on Earth, the Laurentian Great Lakes have significant influence on local and regional weather and climate through their unique physical features compared with the surrounding land. Due to the limited spatial resolution and computational efficiency of general circulation models (GCMs), the Great Lakes are geometrically ignored or idealized into several grid cells in GCMs. Thus, the nested regional climate modeling (RCM) technique, known as dynamical downscaling, serves as a feasible solution to fill the gap. The latest Weather Research and Forecasting model (WRF) is employed to dynamically downscale the historical simulation produced by the Geophysical Fluid Dynamics Laboratory-Coupled Model (GFDL-CM3) from 1970-2005. An updated lake scheme originated from the Community Land Model is implemented in the latest WRF version 3.6. It is a one-dimensional mass and energy balance scheme with 20-25 model layers, including up to 5 snow layers on the lake ice, 10 water layers, and 10 soil layers on the lake bottom. The lake scheme is used with actual lake points and lake depth. The preliminary results show that WRF-Lake model, with a fine horizontal resolution and realistic lake representation, provides significantly improved hydroclimates, in terms of lake surface temperature, annual cycle of precipitation, ice content, and lake-effect snowfall. Those improvements suggest that better resolution of the lakes and the mesoscale process of lake-atmosphere interaction are crucial to understanding the climate and climate change in the Great Lakes region.

    The natural history of congenitally corrected transposition of the great arteries is of clinical/surgical importance once the fetus is born without heart block or signs of heart failure. Without significant tricuspid valve malformation, associated defects such as ventricular septal defect and left ventricular outflow obstruction can be repaired surgically. The mortality and long-term outcome appear to be linked strongly with the severity of tricuspid valve regurgitation. Some patients with an intact ventricular septum and no right ventricular dysfunction will live long lives without detection, and some women will successfully complete pregnancy.

    Rising atmospheric carbon dioxide (CO2) concentration and increased air temperature and climatic variability concerns have prompted considerable interest regarding CO2 dynamics of terrestrial ecosystems in response to major climatic and biophysical factors. However, detailed information on CO2 dynamics in winter wheat (Triticum aestivum L.) and canola (Brassica napus L.) under different agricultural management practices is lacking. As a part of the GRL-FLUXNET, a cluster of eight eddy covariance (EC) systems was deployed on the 420-ha Grazinglands Research on agroEcosystems and the ENvironment (GREEN) Farm at the United States Department of Agriculture, Agricultural Research Service (USDA-ARS), Grazinglands Research Laboratory (GRL), El Reno, OK. The GRL is also one of 18 USDA-ARS Long-Term Agroecosystem Research (LTAR) network sites in the United States. A 4-year crop rotation plan at the farm includes winter wheat for grain only, graze-grain, and graze-out, and canola under conventional till and no-till management conditions. Biometric measurements such as biomass, leaf area index (LAI), canopy cover %, canopy height, and chlorophyll content were collected approximately every 16 days to coincide with Landsat satellite overpass dates. As expected, biomass and LAI were highest in the grain only wheat fields followed by graze-grain and graze-out wheat fields, but they were similar for till and no-till wheat fields within the same grazing practice. Biomass and LAI were similar in till and no-till canola in fall 2016, but both were substantially lower in no-till compared to tilled canola during spring 2017 due to more severe winter damage. Because net ecosystem CO2 exchange (NEE) is strongly regulated by vegetation cover, the magnitudes of NEE were highest in the grain only wheat fields due to more biomass and LAI, followed by graze-grain and graze-out wheat fields. Similarly, the magnitudes of NEE were also higher in tilled canola (i.e., higher biomass and LAI) than

    Both field and laboratory studies demonstrate that hummingbirds (Apodiformes, Trochilidae) have exceptional spatial memory. The complexity of spatial-temporal information that hummingbirds must retain and use daily is probably subserved by the hippocampal formation (HF), and therefore, hummingbirds should have a greatly expanded HF. Here, we compare the relative size of the HF in several hummingbird species with that of other birds. Our analyses reveal that the HF in hummingbirds is significantly larger, relative to telencephalic volume, than any bird examined to date. When expressed as a percentage of telencephalic volume, the hummingbird HF is two to five times larger than that of caching and non-caching songbirds, seabirds and woodpeckers. This HF expansion in hummingbirds probably underlies their ability to remember the location, distribution and nectar content of flowers, but more detailed analyses are required to determine the extent to which this arises from an expansion of HF or a decrease in size of other brain regions.

    Rheumatoid arthritis (RA) is a chronic, systemic, autoimmune disease. Physiotherapy interventions for people with RA are predominantly targeted at ameliorating disability resulting from articular and peri-articular manifestations of the disease and providing advice and education to improve functional capacity and quality of life. To ensure safe and effective care, it is critical that physiotherapists are able to identify potentially serious articular and peri-articular manifestations of RA, such as instability of the cervical spine. Additionally, as primary contact professionals, it is essential that physiotherapists are aware of the potentially serious extra-articular manifestations of RA. This paper provides an overview of the practice-relevant manifestations associated with RA that might warrant further investigation by a medical practitioner (red flags), their relevance to physiotherapy practice, and recommended management pathways.

    The Laurentian Great Lakes region provides opportunities for shipping, recreation, and consumptive water use to a large part of the United States and Canada. Water levels in the lakes fluctuate yearly, but attempts to model the system are inadequate because the water and energy budgets are still not fully understood. For example, water levels in the Great Lakes experienced a 15-year low period ending in 2013, the recovery of which has been attributed partially to decreased evaporation and increased precipitation and runoff. Unlike precipitation, the exchange of water vapor between the lake and the atmosphere through evaporation or condensation is difficult to measure directly. However, estimates have been constructed using off-shore eddy covariance direct measurements of latent heat fluxes, remote sensing observations, and a small network of monitoring buoys. When the lake surface temperature is colder than air temperature as it is in spring, condensation is larger than evaporation. This is a relatively small component of the net annual water budget of the lakes, but the total amount of condensation may be important for seasonal energy fluxes and atmospheric deposition of pollutants and nutrients to the lakes. Seasonal energy fluxes determine, and are influenced by, ice cover, water and air temperatures, and evaporation in the Great Lakes. We aim to quantify the amount of spring condensation on the Great Lakes using the National Center for Atmospheric Prediction North American Regional Reanalysis (NCEP NARR) Data for Winter 2013 to Spring 2017 and compare the condensation values of spring seasons following high volume, high duration and low volume, low duration ice cover.

    This study investigated the levels of public trust in organizations associated with the Great East Japan Earthquake. In Study 1 (N = 639), the levels of trust in eight organizations as well as the determinants of trust--perceived salient value similarity (SVS), ability, and motivation--were measured twice, first immediately after the earthquake and then a year later. The results indicated that the trust levels for six of the eight organizations had been preserved, supporting the double asymmetric effect of trust. The results of structural equation modeling (SEM) revealed that SVS explained trust more when the organization had been less trusted. Trust in the organization explains well the perceived reduction of the target risk. The results of SEM in Study 2 (N = 1,030) replicated those of Study 1, suggesting the stability of the explanatory power of the determinants of trust. Implications of the study for risk management practices are discussed.

    Full Text Available Dextrotransposition of the great arteries (DTGA is a common cardiac cause of cyanosis in newborn infants that can cause acidosis and death within a short period of time unless there is a large atrial-level shunt or a patent ductus arteriosus. Here, we report a case of prenatal diagnosis of DTGA at 24+1 gestational weeks. In a tilted 4-chamber view, the pulmonary trunk branched to the left and the right pulmonary, with its root connected to the left ventricle outflow tract. In the short-axis view, the pulmonary trunk was shown to be parallel with the ascending aortic root. Cesarean section was performed due to the nonreassuring fetal status at 38+5 gestational weeks. The male neonate appeared to have mild cyanotic symptoms and weighed 3,108 g. Apgar scores were 8 and 9 at 1 and 5 minutes, respectively. Neonatal echocardiography was performed immediately after birth and the findings confirmed DTGA associated with atrial septal defect secundum. Postnatally, angiography confirmed the echocardiographic diagnosis of DTGA with a large atrial septal defect secundum and a large patent ductus arteriosus. Jatene arterial switch operation and atrial septal defect closure with Gore-Tex patch were performed. The neonate withstood the operation well and was discharged 27 days after birth weighing 2,950 g and in a stable condition. Prenatal diagnosis of DTGA can greatly aid to prepare the patient's family and the surgeon and significantly improve the outcome of complex heart disease in the neonatal period.

    2016-03-01

    In the present study, we investigated associations of macro-economic conditions - the Great Recession - with cellular epigenetic aging, allostatic load, and self-reported health, in a group that experiences significant health disparities, African Americans. A sample of 330 African American adolescents in Georgia was followed from pre-recession (2007, M age=16.6) to post-recession (2010, M age=19.3). Economic data were collected in both 2007 and 2010. Three groups were formed to represent economic trajectories across the period of the Great Recession (stable low economic hardship, downward mobility, and stable high economic hardship). At age 19, measures of cellular epigenetic aging (derived from leukocyte DNA methylation profiles, reflecting the disparity between a person's biological and chronological age), allostatic load (composite of blood pressure, C reactive protein, cortisol, epinephrine, norepinephrine, and body mass index), and adolescent self-report of health were obtained. Linear trend analyses documented significant differences across all outcomes. The more time adolescents spent under economic hardship, the higher their epigenetic aging [estimate=1.421, SE=0.466, p=.002] and allostatic load [estimate=1.151, SE=0.375, p=.002] scores, and the worse their self-report of health [estimate=4.957, SE=1.800, p=.006]. Specific group comparisons revealed that adolescents in the downward mobility group had higher levels of allostatic load than adolescents in the stable low hardship group [p<.05]. Overall, these findings suggest that the health profiles of African American youth may in part be shaped by environmental macro-economic societal conditions, and that effects on biological markers can be detected relatively early in life.

    2003-05-01

    This study sought to clarify if Alexander the Great indulged pathologically in alcohol and whether it contributed to his death. The texts of the historians Diodorus of Sicily, Plutarch, Arrian, Curtius Rufus, Athenaeus, Aelian and Justin were studied, with their information concerning wine consumption by Macedonians, and especially Alexander, and were evaluated. The surviving historical texts, all later than Alexander's epoch, are based on a series of contemporary histories and especially on the 'Royal Journals', an official diary written in the imperial court. Alexander consumed large quantities of undiluted wine periodically, reaching pathological intoxication. However, the existing data do not provide convincing evidence that Alexander the Great manifested abuse of or dependence on alcohol according to DSM-IV or ICD-10 criteria and it seems unlikely that alcohol was involved in his untimely death.

    2015-02-01

    The literature reports great variation in the knowledge levels and application of the recent changes of cervical cancer screening guidelines into clinical practice. Evidence-based screening guidelines for the prevention and early detection of cervical cancer offers healthcare providers the opportunity to improve practice patterns among female adolescents by decreasing psychological distress as well as reducing healthcare costs and morbidities associated with over-screening. The purpose of this pilot intervention study was to determine the effects of a Web-based continuing education unit (CEU) program on advanced practice nurses' (APNs) knowledge of current cervical cancer screening evidence-based recommendations and their application in practice. This paper presents a process improvement project as an example of a way to disseminate updated evidence-based practice guidelines among busy healthcare providers. This Web-based CEU program was developed, piloted, and evaluated specifically for APNs. The program addressed their knowledge level of cervical cancer and its relationship with high-risk human papillomavirus. It also addressed the new cervical cancer screening guidelines and the application of those guidelines into clinical practice. Results of the study indicated that knowledge gaps exist among APNs about cervical cancer screening in adolescents. However, when provided with a CEU educational intervention, APNs' knowledge levels increased and their self-reported clinical practice behaviors changed in accordance with the new cervical cancer screening guidelines. Providing convenient and readily accessible up-to-date electronic content that provides CEU enhances the adoption of clinical practice guidelines, thereby decreasing the potential of the morbidities associated with over-screening for cervical cancer in adolescents and young women. © 2014 Sigma Theta Tau International.

  13. Advanced clinical practice for radiographers in Great Britain: professional roles, accountability and the educational provision

    International Nuclear Information System (INIS)

    Hogg, P.

    2004-01-01

    A change in British health care has resulted in a broadening of roles and responsibilities beyond 'traditional boundaries' for a range of health care professionals. This has occurred because of staff shortages (particularly within the medical profession) and the recognition that many 'non-doctor' health care staff can make safe, competent and effective contributions outside their 'normal' sphere of responsibilities. In the context of advanced clinical practice, this paper will explain the current arrangements for radiographers' roles and responsibilities, their accountability and the educational provision that underpins the development of competencies at these higher clinical levels. Some advanced roles that British radiographers perform, within their current normal responsibilities, will be identified and some British legislation and professional body guidance that make role advancement possible will be outlined. The article will conclude with an indication of the educational level at which the advanced competencies are learned and assessed. (author)

    From historical sources, it is evident that Alexander the Great was indebted to one of his teachers, Aristotle of Stagira. It was the teaching of Aristotle that evoked all the nascent talents of young Alexander and turned him into a great man. Alexander was extremely interested in the secrets of medicine and considered it an art. The medical knowledge he acquired from Aristotle may have saved his life and the lives of his troops on many occasions. If Alexander did not possess medical knowledge and if his everyday life had not been so greatly influenced by medicine, he might never have been able to create his empire.

    Full Text Available Meditation proficiency is related to trait-like (learned effects on brain function, developed over time. Previous studies show increases in EEG power in lower frequency bands (theta, alpha in experienced meditators in both meditation states and baseline conditions. Higher gamma band power has been found in advanced Buddhist meditators, yet it is not known if this occurs in Yoga meditation practices. This study used eLORETA to compare differences in cortical source activity underlying scalp EEG from intermediate (mean experience 4 years and advanced (mean experience 30 years Australian meditators from the Satyananda Yoga tradition during a body-steadiness meditation, mantra meditation and non-meditation mental calculation condition. Intermediate Yoga meditators showed greater source activity in low frequencies (particularly theta and alpha1 during mental calculation, body-steadiness and mantra meditation. A similar spatial pattern of significant differences was found in all conditions but the number of significant voxels was double during body-steadiness and mantra meditation than in the non-meditation (calculation condition. These differences were greatest in right (R superior frontal and R precentral gyri and extended back to include the R parietal and occipital lobes. Advanced Yoga meditators showed greater activity in high frequencies (beta and especially gamma in all conditions but greatly expanded during meditation practice. Across all conditions (meditation and non-meditation differences were greatest in the same regions; R insula, R inferior frontal gyrus and R anterior temporal lobe. Distinct R core networks were identified in alpha1 (8-10 Hz and gamma (25-42 Hz bands respectively. The voxels recruited to these networks greatly expanded during meditation practice to include homologous regions of the left hemisphere. Functional interpretation parallels traditionally described stages of development in Yoga proficiency.

    Studying the isotopic composition of the hair of two rodent species trapped in the territories of Great Cormorant colonies, we aimed to show that Great Cormorants transfer biogens from aquatic ecosystems to terrestrial ecosystems, and that these substances reach small mammals through the trophic cascade, thus influencing the nutrient balance in the terrestrial ecosystem. Analysis of δ"1"3C and δ"1"5N was performed on two dominant species of small mammals, Apodemus flavicollis and Myodes glareolus, inhabiting the territories of the colonies. For both species, the values of δ"1"3C and δ"1"5N were higher in the animals trapped in the territories of the colonies than those in control territories. In the hair of A. flavicollis and M. glareolus, the highest values of δ"1"5N (16.31 ± 3.01‰ and 17.86 ± 2.76‰, respectively) were determined in those animals trapped in the biggest Great Cormorant colony. δ"1"5N values were age dependent, highest in adult A. flavicollis and M. glareolus and lowest in juvenile animals. For δ"1"3C values, age-dependent differences were not registered. δ"1"5N values in both small mammal species from the biggest Great Cormorant colony show direct dependence on the intensity of influence. Biogenic pollution is at its strongest in the territories of the colonies with nests, significantly diminishing in the ecotones of the colonies and further in the control zones, where the influence of birds is negligible. Thus, Great Cormorant colonies alter ecosystem functioning by enrichment with biogens, with stable isotope values in small mammals significantly higher in the affected territories. - Highlights: • Cormorants transport nutrients from water to land ecosystems and pollute biogenically. • We studied stable isotope composition of small mammal hair in 3 cormorant colonies. • δ"1"3C and δ"1"5N were measured using elemental analyzer–isotope ratio mass spectrometer. • δ"1"3C and δ"1"5N values were higher in rodents inhabiting

    Great Exuma has been a UNESCO Eco-hydrology Project Site with a focus on coastal restoration and flood management. Great Exuma and its largest settlement, George Town, support a population of just over 8.000 people on an island dominated by extensive coastal wetlands. The Victoria Pond Eco-Hydrology project restored flow and drainage to highly-altered coastal wetlands to reduce flooding of the built environment as well as regain ecological function. The project was designed to show the value of a protected wetland and coastal environment within a populated settlement; demonstrating that people can live alongside mangroves and value "green" infrastructure for flood protection. The restoration project was initiated after severe storm flooding in 2007 with Tropical Storm Noel. In 2016, the passing of Hurricane Matthew had unprecedented impacts on the coastal communities of Great Exuma, challenging past practices in restoration and flood prevention. This talk reviews the loss of natural capital (for example, fish populations, mangroves, salt water inundation) from Hurricane Matthew based on a rapid response survey of Great Exuma. The surprisingly find was the impact of storm surge on low-lying areas used primarily for personal farms and small-scale agriculture. Although women made up the overwhelming majority of people who attended Coastal Restoration workshops, women were most adversely impacted by the recent hurricane flooding with the loss of their small low-lying farms and gardens. Although increasing culverts in mangrove creeks in two areas did reduce building flood damage, the low-lying areas adjacent to mangroves, mostly ephemeral freshwater wetlands, were inundated with saltwater, and seasonal crops in these areas were destroyed. These ephemeral wetlands were designed as part of the wetland flooding system, it was not known how important these small areas were to artisanal farming on Great Exuma. The size and scope of Hurricane Matthew passing through the

Neuropraxia of the great auricular nerve (GAN is an uncommon complication of shoulder surgery, with the patient in the beach chair position. We report a case of great auricular neuropraxia associated with direct compression by a horseshoe headrest, used in routine positioning for uncomplicated shoulder surgery. In this case, an arthroscopic approach was taken, under regional anesthesia with sedation in the beach chair position. The GAN, a superficial branch of the cervical plexus, is vulnerable to neuropraxia due to its superficial anatomical location. We recommend that for the procedures of the beach chair position, the auricle be protected and covered with cotton and gauze to avoid direct compression and the position of the head and neck be checked and corrected frequently.

    Success in problem solving, a form of innovativeness, can help animals exploit their environments, and recent research suggests that it may correlate with reproductive success. Innovativeness has been proposed to be especially beneficial in urbanized habitats, as suggested by superior problem-solving performance of urban individuals in some species. If there is stronger selection for innovativeness in cities than in natural habitats, we expect problem-solving performance to have a greater positive effect on fitness in more urbanized habitats. We tested this idea in great tits (Parus major) breeding at two urban sites and two forests by measuring their problem-solving performance in an obstacle-removal task and a food-acquisition task. Urban pairs were significantly faster problem-solvers in both tasks. Solving speed in the obstacle-removal task was positively correlated with hatching success and the number of fledglings, whereas performance in the food-acquisition task did not correlate with reproductive success. These relationships did not differ between urban and forest habitats. Neophobia, sensitivity to human disturbance, and risk taking in the presence of a predator did not explain the relationships of problem-solving performance either with habitat type or with reproductive success. Our results suggest that the benefit of innovativeness in terms of reproductive success is similar in urban and natural habitats, implying that problem-solving skills may be enhanced in urban populations by some other benefits (e.g. increased survival) or reduced costs (e.g. more opportunities to gain practice with challenging tasks).

    Erdogan, Ibrahim

    The purposes of the study were: (1) to examine the effectiveness of the Iowa Chautauqua Professional Development Program (ICPDP) in moving elementary science teachers toward the use of more constructive teaching practices and (2) to investigate the effectiveness of different levels of teaching practices, especially in terms of a sample of teachers achieving "expert" state at the end of program compared with some attaining only with "competent" level. The variables considered were their perceptions of their own classroom practices, stated philosophy of teaching and learning, and their actual classroom practices and question asking behaviors observed via videotape recording. Structured questionnaires, focus group interviews, teacher reflections, and examination of lesson modules were used to collect data from thirty-three K-5 in-service teachers who were involved in a one-year ICPDP. Qualitative and quantitative analyses of data revealed that: (1) Teacher perceptions regarding their teaching and learning, and their actual teaching practices in classroom in terms of constructivist approaches were significantly changed after participation in the ICPDP. (2) Teacher perceptions of their classroom practices and stated philosophies of teaching and learning have a great affect on their actual practices that can be observed. (3) Teacher stated philosophies of teaching and learning significantly influence the quantity and quality of their use of questions in their classrooms. (4) The "expert" teachers accept students' alternative answers and deliberately ask high cognitive level questions that enable students to think critically and to guide them based on what the students are thinking. Alternatively, the "competent" teachers do not follow student responses and used questions which do not help students to understand their current level of understanding nor encourage students to reflect on their own thinking. (5) The role of "expert" teacher is more geared toward challenging

    There is increasing interest of the worldwide kidney community in home hemodialysis (HHD). This is due to emerging evidence of its superiority over conventional hemodialysis (HD), largely attributed to improved outcomes on intensive schedule HD, best deployed in patient's own homes. Despite published work in this area, universal uptake remains limited and reasons are poorly understood. All those who provide HD care were invited to participate in a survey on HHD, initiated to understand the beliefs, attitudes, and practice patterns of providers offering this therapy. The survey was developed and posted on the Nephrology Dialysis Transplantation-Educational (NDT-E) website. Two hundred and seventy-two responses were deemed suitable for complete analysis. It is apparent from the survey that there is great variability in the prevalence of HHD. Physicians have a great deal of interest in this modality, with majority viewing home as being the ideal location for the offer of intensive HD schedules (55%). A significant number (21%) feel intensive HD may be offered even outside the home setting. Those who offer this therapy do not see a financial disadvantage in it. Many units identify lack of appropriately trained personnel (35%) and funding for home adaptation (50.4%) as key barriers to widespread adoption of this therapy. Despite the interest and belief in this therapy among practitioners, HHD therapy is still not within reach of a majority of patients. Modifiable organizational, physician, and patient factors exist, which could potentially redefine the landscape of HHD provision. Well-designed systematic research of national and local barriers is needed to design interventions to help centers facilitate change. © 2014 International Society for Hemodialysis.

    I propose that Alexander the Great died of acute pancreatitis secondary to heavy alcohol consumption and a very rich meal. The cause of death of prominent historic or artistic figures attracts considerable interest of historians and researchers. This is especially the case for Alexander the Great. More than 20,000 publications, books, or monographs on the life and work of Alexander the Great have been published. There are several theories and hypotheses regarding the cause of his death, that are based on historic descriptions, diaries, notations, and interpretations of events. It is inevitable that history and myth intermingle in any investigative approach, no matter how scholarly. In this article, on the basis of several historic sources. I have made an effort to reconstruct the final 14 days of his life and record the course of medical events that preceded his death with the formulation of a plausible diagnosis.

    . Results from all three study collections reveal that among the great apes, gorillas (87-92%) and orangutans (91%) have a significantly higher prevalence of canine enamel defects than chimpanzees (22-48%). Sex differences in canine enamel hypoplasia are small and not statistically significant in any great ape. Factors influencing intergroup variation in prevalence of enamel defects and their distribution on the canine crown, including physiological stress and interspecific dento-gnathic morphological variation, are evaluated.

    2011-01-01

    The present article analyzes the environmental practices of the social actors related to the tourist companies of the municipality of Valle de Bravo, Mexico State. The environmental practices were considered from the socioeconomic point of view, including not only the natural resources management, but also the social and economic environment. Considering the previous, using a methodological proposal based on the theory of complex systems, the effects on the above mentioned environments of this tourist destination were analyzed, allowing to holistically visualizing the situation that prevails towards the environmental caring performed by all the social actors of the locality. The results show a great weakness in the implementation of the above mentioned practices, due to the fact that nowadays these practices are imposed by the municipal government and are not an initiative of the actors of the tourist companies. For this reason, the conditions of environmental deterioration in Valle de Bravo are increasing. Based on the results, some recommendations are proposed for the implementation and improvement of environmental practices that contribute to the conservation and care of the environment.

    2005-04-01

    In response to a growing concern regarding physician discrimination in the workplace, this study was developed to: (1) describe the types of discrimination that exist for the practicing physician and (2) determine which groups of physicians are more likely to experience the various forms of discrimination. Surveys were mailed to 1930 practicing physicians in Massachusetts. Participants were asked if they had encountered discrimination, how significant the discrimination was against a specific group, the frequency of personal discrimination, and the type of discrimination. Factor analysis identified four types of discrimination: career advancement, punitive behaviors, practice barriers and hiring barriers. A total of 445 responses were received (a 24% response rate). Sixty-three percent of responding physicians had experienced some form of discrimination. Respondents were women (46%), racial/ethnic minorities (42%) and international medical graduates (IMGs) (40%). In addition, 26% of those classified as white were also IMGs. Over 60% of respondents believed discrimination against IMGs was very or somewhat significant. Almost 27% of males acknowledged that gender bias against females was very or somewhat significant. IMGs were more likely to indicate that discrimination against IMGs was significant in their current organization. Of U.S. medical graduates (USMGs) 44% reported that discrimination against IMGs in their current organization was significant. Nonwhites were more likely to report that discrimination based on race/ethnicity was significant. Nearly 29% of white respondents also believed that such discrimination was very or somewhat significant. Physicians practicing in academic, research, and private practice sectors experience discrimination based on gender, ethnic/racial, and IMG status.

  18. The Great American Recession and forgone healthcare: Do widened disparities between African-Americans and Whites remain?

    2017-01-01

    During the Great Recession in America, African-Americans opted to forgo healthcare more than other racial/ethnic groups. It is not understood whether disparities in forgone care returned to pre-recession levels. Understanding healthcare utilization patterns is important for informing subsequent efforts to decrease healthcare disparities. Therefore, we examined changes in racial disparities in forgone care before, during, and after the Great Recession. Data were pooled from the 2006-2013 National Health Interview Survey. Forgone medical, mental, and prescription care due to affordability were assessed among African-Americans and Whites. Time periods were classified as: pre-recession (May 2006-November 2007), early recession (December 2007-November 2008), late recession (December 2008-May 2010) and post-recession (June 2010-December 2013). Multivariable logistic regressions of race, interacted with time periods, were used to identify disparities in forgone care controlling for other demographics, health insurance coverage, and having a usual place for medical care across time periods. Adjusted Wald tests were performed to identify significant changes in disparities across time periods. The sample consisted of 110,746 adults. African-Americans were more likely to forgo medical care during the post- recession compared to Whites (OR = 1.16, CI = 1.06, 1.26); changes in foregone medical care disparities were significant in that they increased in the post-recession period compared to the pre-recession (OR = 1.17, CI = 1.08, 1.28 and OR = 0.89, CI = 0.77, 1.04, respectively, adjusted Wald Test p-value Great Recession and may be a result of outstanding issues related to healthcare access, cost, and quality. While health insurance is an important component of access to care, it alone should not be expected to remove these disparities due to other financial constraints. Additional strategies are necessary to close remaining gaps in care widened by the Great Recession.

In the article, the copyright attribution was incorrect. The copyright is "In the public domain". The online version of this article has been corrected. (The following abstract of the original article appeared in record 2014-04967-001.) In the decade after World War II, psychologists, eager to bring the benefits of counseling to larger numbers, convinced hundreds of American colleges and universities to establish counseling centers. Inspired by the educational-vocational counseling center founded by psychologists at the University of Minnesota in 1932, Carl R. Rogers's "client-centered" methods of personal adjustment counseling, and the 400-plus college counseling centers created by the Veterans Administration to provide the educational-vocational counseling benefit promised to returning World War II servicemen under the 1944 GI Bill, these counseling psychologists created a new place to practice where important currents in psychology, higher education, and federal policy converged and where they attempted to integrate educational-vocational counseling with personal adjustment counseling based on techniques from psychotherapy. By the mid-1960s, half of America's colleges and universities had established counseling centers, and more than 90% offered students educational, vocational, and psychological counseling services, a great achievement of the first generation of counseling psychologists.

The article presents an overview of the different approaches to the definition of the term «individual educational path» (IEP. It also gives a brief overview of the existing terms in the Russian terminological system, which are close in meaning to the term above. The author formulates her own tentative definition of the term «IEP» which is based on the analysis made. The article further addresses the solution to the problem of the individualization of higher education learning process in Great Britain, which is described through the term «Personal Development Planning». The meaning of the term is shown through the set of actions: planning, doing things, recording of the self experience, reviewing and evaluating, using the personal knowledge derived from reflection and self understanding as well as own learning abilities to plan future actions. In conclusion, the meanings of the terms «IEP» and «PDP» are compared. The author emphasires the importance of studying Great Britain's experience - the practice of solving problems connected with the individualization of the university learning process and the possibilities to use it to facilitate the implementation of students' individual educational paths in Russian higher education institutions.

    The runoff of pesticides (insecticides, herbicides and fungicides) from agricultural lands is a key concern for the health of the iconic Great Barrier Reef, Australia. Relatively low levels of herbicide residues can reduce the productivity of marine plants and corals. However, the risk of these residues to Great Barrier Reef ecosystems has been poorly quantified due to a lack of large-scale datasets. Here we present results of a study tracing pesticide residues from rivers and creeks in three catchment regions to the adjacent marine environment. Several pesticides (mainly herbicides) were detected in both freshwater and coastal marine waters and were attributed to specific land uses in the catchment. Elevated herbicide concentrations were particularly associated with sugar cane cultivation in the adjacent catchment. We demonstrate that herbicides reach the Great Barrier Reef lagoon and may disturb sensitive marine ecosystems already affected by other pressures such as climate change. - Herbicide residues have been detected in Great Barrier Reef catchment waterways and river water plumes which may affect marine ecosystems.

  4. Testing Significance Testing

    2018-04-01

    Full Text Available The practice of Significance Testing (ST remains widespread in psychological science despite continual criticism of its flaws and abuses. Using simulation experiments, we address four concerns about ST and for two of these we compare ST’s performance with prominent alternatives. We find the following: First, the 'p' values delivered by ST predict the posterior probability of the tested hypothesis well under many research conditions. Second, low 'p' values support inductive inferences because they are most likely to occur when the tested hypothesis is false. Third, 'p' values track likelihood ratios without raising the uncertainties of relative inference. Fourth, 'p' values predict the replicability of research findings better than confidence intervals do. Given these results, we conclude that 'p' values may be used judiciously as a heuristic tool for inductive inference. Yet, 'p' values cannot bear the full burden of inference. We encourage researchers to be flexible in their selection and use of statistical methods.

    Objective The purposes of this study were to (1) quantify dentists' practice patterns regarding caries prevention and (2) test the hypothesis that certain dentists' characteristics are associated with these practice patterns. Design The study used a cross-sectional study design consisting of a questionnaire survey. Participants The study queried dentists who worked in outpatient dental practices who were affiliated with the Dental Practice-Based Research Network Japan, which seeks to engage dentists in investigating research questions and sharing experiences and expertise (n=282). Measurement Dentists were asked about their practice patterns regarding caries preventive dentistry. Background data on patients, practice and dentist were also collected. Results 38% of dentists (n=72) provided individualised caries prevention to more than 50% of their patients. Overall, 10% of the time in daily practice was spent on caries preventive dentistry. Dentists who provided individualised caries prevention to more than 50% of their patients spent significantly more time on preventive care and less time on removable prosthetics treatment, compared to dentists who did not provide individualised caries prevention. Additionally, they provided oral hygiene instruction, patient education, fluoride recommendations, intraoral photographs taken and diet counselling to their patients significantly more often than dentists who did not provide individualised caries prevention. Multiple logistic regression analysis suggested that the percentage of patients interested in caries prevention and the percentage of patients who received hygiene instruction, were both associated with the percentage of patients who receive individualised caries prevention. Conclusions We identified substantial variation in dentists' practice patterns regarding preventive dentistry. Individualised caries prevention was significantly related to provision of other preventive services and to having a higher percentage

    The aim of this study was to explore the current role of general practice nurses and the scope of nursing practice to inform the development of national professional practice standards for Australian general practice nurses. Increasing numbers of nurses have been employed in Australian general practice to meet the growing demand for primary care services. This has brought significant changes to the nursing role. Competency standards for nurses working in general practice were first developed in Australia in 2005, but limited attention has been placed on articulating the contemporary scope of practice for nurses in this setting. Concurrent mixed methods design. Data collection was conducted during 2013-2014 and involved two online surveys of Registered and Enrolled Nurses currently working in general practice, a series of 14 focus groups across Australia and a series of consultations with key experts. Data collection enabled the development of 22 Practice Standards separated into four domains: (i) Professional Practice; (ii) Nursing Care; (iii) General Practice Environment and (iv) Collaborative Practice. To differentiate the variations in enacting these Standards, performance indicators for the Enrolled Nurse, Registered Nurse and Registered Nurse Advanced Practice are provided under each Standard. The development of national professional practice standards for nurses working in Australian general practice will support ongoing workforce development. These Standards are also an important means of articulating the role and scope of the nurses' practice for both consumers and other health professionals, as well as being a guide for curriculum development and measurement of performance. © 2017 John Wiley & Sons Ltd.

    Ng, Patrick; Keich, Uri

    2008-01-01

    We recently introduced a biologically realistic and reliable significance analysis of the output of a popular class of motif finders. In this paper we further improve our significance analysis by incorporating local base composition information. Relying on realistic biological data simulation, as well as on FDR analysis applied to real data, we show that our method is significantly better than the increasingly popular practice of using the normal approximation to estimate the significance of a finder's output. Finally we turn to leveraging our reliable significance analysis to improve the actual motif finding task. Specifically, endowing a variant of the Gibbs Sampler with our improved significance analysis we demonstrate that de novo finders can perform better than has been perceived. Significantly, our new variant outperforms all the finders reviewed in a recently published comprehensive analysis of the Harbison genome-wide binding location data. Interestingly, many of these finders incorporate additional information such as nucleosome positioning and the significance of binding data.

    We present a temporally fine-grained characterization of faculty practice in workshop-style introductory physics courses. Practice is binned in five minute intervals and coded through two complementary observational protocols: the Reform Teaching Observation Protocol provides a summative assessment of fidelity to reform-teaching principles, while the Teaching Dimensions Observation Protocol records direct practice. We find that the TDOP's direct coding of practice explains nuances in the holistic RTOP score, with higher RTOP scores corresponding to less lecture, but not necessarily more student-directed activities. Despite using similar materials, faculty show significant differences in practice that manifests in both TDOP and RTOP scores. We also find a significant dependence of practice on course subject reflected in both RTOP and TDOP scores, with Electricity & Magnetism using more instructor-centered practices (lecture, illustration, etc.) than Mechanics courses.

    Since 1996, the emergence of Asian-origin highly pathogenic avian influenza subtype H5N1 has spurred great concern for the global poultry industry. In the United States, there is concern over the potential of a foreign avian disease incursion into the country. Noncommercial poultry operations, such as upland game bird facilities in the United States, may serve as a potential source of avian disease introduction to other bird populations including the commercial poultry industry, backyard flocks, or wildlife. In order to evaluate how to prevent disease transmission from these facilities to other populations, we examined biosecurity practices and bird movement within the upland game bird industry in the United States. Persons that held a current permit to keep, breed, or release upland game birds were surveyed for information on biosecurity practices, flock and release environments, and bird movement parameters. Biosecurity practices vary greatly among permit holders. Many facilities allow for interaction between wild birds and pen-reared birds, and there is regular long-distance movement of live adult birds among facilities. Results suggest that upland game bird facilities should be targeted for biosecurity education and disease surveillance efforts.

    Full Text Available The paper investigates whether the stock market of Bangladesh can be related with the last world recession. The Pearson’s correlation analysis model was used to find the correlation between the Dhaka Stock Exchange General index and real GDP growth rate of the world. The findings show that no statistically significant correlation exists between the two variables inferring that the stock market of Bangladesh was not significantly affected by ‘the great recession’ (2007-2009. The findings of this study are inconsistent with the results of previous studies which claimed that the Bangladesh stock market shares a common stochastic trend with the capital market of USA. The results of this study may be explained mainly by domestic factors such as low market capitalization, market inefficiency, strict monitoring and control by the Security and Exchange Commission and low international participation in the stock market of Bangladesh. All these factors, along with the inconsistency with past results, instigate further investigation.

    2015-09-01

    Environmental pollution is one of the main causes of human cancer. Exposures to environmental carcinogens result in genetic and epigenetic alterations which induce cell transformation. Epigenetic changes caused by environmental pollution play important roles in the development and progression of environmental pollution-related cancers. Studies on DNA methylation are among the earliest and most conducted epigenetic research linked to cancer. In this review, the roles of DNA methylation in carcinogenesis and their significance in clinical medicine were summarized, and the effects of environmental pollutants, particularly air pollutants, on DNA methylation were introduced. Furthermore, prospective applications of DNA methylation to environmental pollution detection and cancer prevention were discussed.

    Prediction of yield is a critical component of fisheries management. The development of sound yield prediction methodology and the application of the results of yield prediction are central to the evolution of strategies to achieve stated goals for Great Lakes fisheries and to the measurement of progress toward those goals. Despite general availability of species yield models, yield prediction for many Great Lakes fisheries has been poor due to the instability of the fish communities and the inadequacy of available data. A host of biological, institutional, and societal factors constrain both the development of sound predictions and their application to management. Improved predictive capability requires increased stability of Great Lakes fisheries through rehabilitation of well-integrated communities, improvement of data collection, data standardization and information-sharing mechanisms, and further development of the methodology for yield prediction. Most important is the creation of a better-informed public that will in turn establish the political will to do what is required.

The ratio of responding female to male orthodontists was 1:8.8. Overall, more orthodontists were in solo private practice than associateships or partnerships. New Zealand orthodontists were more likely to be in associateships. Australian orthodontists had twice the number of practices (Mean: 2.4; SD: 1.4) than their New Zealand counterparts (Mean: 1.1; SD: 0.3). Orthodontists estimated they saw a mean of 21.3 (SD: 11.3) patients per day. Older orthodontists saw few patients in a day and spent fewer hours in any practice activity in a week. The mean waiting time for a consultation appointment in the private sector in New Zealand was nearly twice that in Australia. There was a significant association between male orthodontists and referral of patients by general dental practitioners. More than three quarters of respondents incorporated retention fees into the treatment fee. Overall, orthodontists were satisfied with the workload and did not want more orthodontists in their geographical area. This study provides a sound basis for consideration of challenges in practice and changes over time.

    Full Text Available With the need to increase crop production to meet the needs of a growing population, protecting the productivity of our soil resource is essential. However, conservationists are concerned that conservation practices that were effective in the past may no longer be effective in the future under projected climate change. In winter wheat cropland in the Southern Great Plains of the U.S., increased precipitation intensity and increased aridity associated with warmer temperatures may pose increased risks of soil erosion from vulnerable soils and landscapes. This investigation was undertaken to determine which conservation practices would be necessary and sufficient to hold annual soil erosion by water under a high greenhouse gas emission scenario at or below the present soil erosion levels. Advances in and benefits of agricultural soil and water conservation over the last century in the United States are briefly reviewed, and challenges and climate uncertainties confronting resource conservation in this century are addressed. The Water Erosion Prediction Project (WEPP computer model was used to estimate future soil erosion by water from winter wheat cropland in Central Oklahoma and for 10 projected climates and 7 alternative conservation practices. A comparison with soil erosion values under current climate conditions and conventional tillage operations showed that, on average, a switch from conventional to conservation tillage would be sufficient to offset the average increase in soil erosion by water under most projected climates. More effective conservation practices, such as conservation tillage with a summer cover crop would be required to control soil erosion associated with the most severe climate projections. It was concluded that a broad range of conservation tools are available to agriculture to offset projected future increases in soil erosion by water even under assumed worst case climate change scenarios in Central Oklahoma.

    Full Text Available To improve the efficiency and competitiveness of the regional economy, an effective interaction between educational institutions in the Great Altai region is needed. The innovation growth can enhancing this interaction. The article explores the state of network structures in the economy and higher education in the border territories of the countries of Great Altai. The authors propose an updated approach to the three-level classification of network interaction. We analyze growing influence of the countries with emerging economies. We define the factors that impede the more stable and multifaceted regional development of these countries. Further, the authors determine indicators of the higher education systems and cooperation systems at the university level between the Shanghai Cooperation Organization countries (SCO and BRICS countries, showing the international rankings of the universities in these countries. The teaching language is important to overcome the obstacles in the interregional cooperation. The authors specify the problems of the development of the universities of the SCO and BRICS countries as global educational networks. The research applies basic scientific logical methods of analysis and synthesis, induction and deduction, as well as the SWOT analysis method. We have indentified and analyzed the existing economic and educational relations. To promote the economic innovation development of the border territories of the Great Altai, we propose a model of regional network university. Modern universities function in a new economic environment. Thus, in a great extent, they form the technological and social aspects of this environment. Innovative network structures contribute to the formation of a new network institutional environment of the regional economy, which impacts the macro- and microeconomic performance of the region as a whole. The results of the research can help to optimize the regional economies of the border

    Using the MAIN galaxy data from the SDSS Data Release 4 (SDSS4), we further study the Sloan Great Wall by three-dimensional cluster analysis. Because the basic properties of Main galaxies change with redshift, we select 50942 Main galaxies having the same redshift region (0.07 ≤ z ≤ 0.09) as the Sloan Great Wall from the Main galaxy sample, and construct our SubMain sample. From the SubMain sample, 2013 isolated galaxies are identified at dimensionless radius r = 1.4. We perform the comparative studies of galaxy properties among the Sloan Great Wall, isolated galaxies and the SubMain sample in different redshift bins. It turns out that the statistical properties of luminosities and sizes of galaxies for the Sloan Great Wall, isolated galaxies and the SubMain sample are almost the same, the proportion of early-type isolated galaxies is relatively low. We also d that mean color of member galaxies of the Sloan Great Wall is redder than that of isolated galaxies. These results indicate that some properties of galaxies may be closely correlated with the environment or clustering. (author)

    Full Text Available Background In the field of education, a great deal of quality improvement is remained to be achieved Assessment of educational courses appears to be necessary for quality improvement in all curriculums, therefore studies for assessment of educational outcomes and impacts are of high priority. In a dentistry faculty, the mouth and dental health care among dentistry students can be considered as a potential indicator of students' educational achievement. Purpose To study knowledge, attitude and practice impact on mouth and dental health care among dentistry faculty students both before and after passing practical periodontic courses in Shaheed University of Medical Sciences during academic year 2001-2002 Methods In this cross-sectional study 140 students of dentistry faculty of Shaheed University of Medical Sciences took part. Necessary data were collected by means of a questionnaire. Knowledge of the subjects on mouth and dental health care were assessed by 10 close-ended questions and their altitude on mouth and dental health care were assessed by 5 Likert scale questions. Assessment of practice was performed in a 3-step researcher-administrated interview. Results Demographic data gathered via questionnaires indicated that 49.6 % {6-1 students of the students who took part in the study were male and 50.4% (65 students were female. of our participants, 59.7% were admitted through Shahed quota, while the rest were admitted through free quota. There was no significant difference in students' knowledge, attitude and practice on mouth and dental health care between the students who had not passed practical courses in periodontics and those who had passed these courses. Conclusions There was no significant association between knowledge, altitude and practice on mouth and dental health care and passing practical courses in periodontics among dentistry faculty students in Shahed University of Medical Science. Our results suggest that students' practice

    The corrected transposition of the great arteries is an usual congenital cardiac malformation, which consists of transposition of great arteries and ventricular inversion, and which is caused by abnormal development of conotruncus and ventricular looping. High frequency of associated cardiac malformations makes it difficult to get accurate morphologic diagnosis. A total of 18 cases of corrected transposition of the great arteries is presented, in which cardiac catheterization and angiocardiography were done at the Department of Radiology, Seoul National University Hospital between September 1976 and June 1981. The clinical, radiographic, and operative findings with the emphasis on the angiocardiographic findings were analyzed. The results are as follows: 1. Among 18 cases, 13 cases have normal cardiac position, 2 cases have dextrocardia with situs solitus, 2 cases have dextrocardia with situs inversus and 1 case has levocardia with situs inversus. 2. Segmental sets are (S, L, L) in 15 cases, and (I, D,D) in 3 cases and there is no exception to loop rule. 3. Side by side interrelationships of both ventricles and both semilunar valves are noticed in 10 and 12 cases respectively. 4. Subaortic type conus is noted in all 18 cases. 5. Associated cardic malformations are VSD in 14 cases, PS in 11, PDA in 3, PFO in 3, ASD in 2, right aortic arch in 2, tricuspid insufficiency, mitral prolapse, persistent left SVC and persistent right SVC in 1 case respectively. 6. For accurate diagnosis of corrected TGA, selective biventriculography using biplane cineradiography is an essential procedure.

    Full Text Available Here we provide a broad overview of the Great Amazon Reef System (GARS based on the first-ever video surveys of the region. This footage supports four major hypotheses: (1 the GARS area may be six times larger than previously suggested (up to 56,000 km2; (2 the GARS may extend deeper than previously suggested (up to 220 m; (3 the GARS is composed of a greater complexity and diversity of habitats than previously recognized (e.g., reef platforms, reef walls, rhodolith beds, and sponge bottoms; and (4 the GARS represents a useful system to test whether a deep corridor connects the Caribbean Sea to the Southwest Atlantic Ocean. We also call attention to the urgent need to adopt precautionary conservation measures to protect the region in the face of increasing threats from extractive oil and gas practices. With less than 5% of the potential area of the GARS surveyed so far, more research will be required to inform a systematic conservation planning approach and determine how best to establish a network of marine protected areas. Such planning will be required to reconcile extractive activities with effective biodiversity conservation in the GARS.

    Diseases of the heart and great vessels were diagnosed by CT through comparison of the pictures with that of control. Indications for CT included pericardiac diseases such as pericardial effusion, pericardiac cyst, pericardiac defect, pericardiac fat pad, and dilated or hypertrophic ventriculus. Of coronary artery diseases, myocardial infarction is the best indication for CT; and coronary artery calcification and coronary artery bypass graft for checking up the patency were also indications for this method. CT was useful for diagnosis of valvular diseases, especially mitral valve diseases, congenital heart diseases with structural abnormalities, abnormalities of the aorta and great veins, and of the pulmonary arteries and veins, and for follow-up of pulmonary congestion.

    Although a great deal of empirical evidence has indicated that retrieval practice is an effective means of promoting learning and memory, very few studies have investigated the strategy in the context of an actual class. The primary purpose of this study was to determine if a series of very brief retrieval quizzes could significantly improve the retention of previously tested information throughout an anatomy and physiology course. A second purpose was to determine if there were any significant differences between expanding and uniform patterns of retrieval that followed a standardized initial retrieval delay. Anatomy and physiology students were assigned to either a control group or groups that were repeatedly prompted to retrieve a subset of previously tested course information via a series of quizzes that were administered on either an expanding or a uniform schedule. Each retrieval group completed a total of 10 retrieval quizzes, and the series of quizzes required (only) a total of 2 h to complete. Final retention of the exam subset material was assessed during the last week of the semester. There were no significant differences between the expanding and uniform retrieval groups, but both retained an average of 41% more of the subset material than did the control group (ANOVA, F = 129.8, P = 0.00, ηp(2) = 0.36). In conclusion, retrieval practice is a highly efficient and effective strategy for enhancing the retention of anatomy and physiology material.

    Full Text Available Transfusion practice might significantly influence patient morbidity and mortality. Between European countries, transfusion practice of red blood cells (RBC greatly differs. Only sparse data are available on transfusion practice of general internal medicine physicians in Switzerland.In this cross-sectional survey, physicians working in general medicine teaching hospitals in Switzerland were investigated regarding their self-reported transfusion practice in anemic patients without acute bleeding. The definition of anemia, transfusion triggers, knowledge on RBC transfusion, and implementation of guidelines were assessed.560 physicians of 71 hospitals (64% responded to the survey. Anemia was defined at very diverging hemoglobin values (by 38% at a hemoglobin <130 g/L for men and by 57% at <120 g/L in non-pregnant women. 62% and 43% respectively, did not define anemia in men and in women according to the World Health Organization. Fifty percent reported not to transfuse RBC according to international guidelines. Following factors were indicated to influence the decision to transfuse: educational background of the physicians, geographical region of employment, severity of anemia, and presence of known coronary artery disease. 60% indicated that their knowledge on Transfusion-related Acute Lung Injury (TRALI did not influence transfusion practice. 50% of physicians stated that no local transfusion guidelines exist and 84% supported the development of national recommendations on transfusion in non-acutely bleeding, anemic patients.This study highlights the lack of adherence to current transfusion guidelines in Switzerland. Identifying and subsequently correcting this deficit in knowledge translation may have a significant impact on patient care.

    Why does modern life revolve around objectives? From how science is funded, to improving how children are educated -- and nearly everything in-between -- our society has become obsessed with a seductive illusion: that greatness results from doggedly measuring improvement in the relentless pursuit of an ambitious goal. In Why Greatness Cannot Be Planned, Stanley and Lehman begin with a surprising scientific discovery in artificial intelligence that leads ultimately to the conclusion that the objective obsession has gone too far. They make the case that great achievement can't be bottled up int

    While of great national and societal significance, and importance in its own right, the Great Artesian Basin of Australia is an iconic example of a continental scale artesian groundwater system. New geochemical, hydrological, and neo-tectonic data suggests that existing models that involve recharge in eastern Australia, relatively simple flow paths and discharge in springs in the western margin require modification. New geochemical data indicate a small volume flux of deeply derived (endogenic) fluids mixing into the aquifer system at a continental scale. Neotectonic data indicates active tectonism today that provides a fluid pathway through faults for the deeply sourced endogenic fluids to discharge in GAB travertine depositing springs. (authors)

    The Great Silence explores the multifaceted problem named after the great Italian physicist Enrico Fermi and his legendary 1950 lunchtime question "Where is everybody?" In many respects, Fermi's paradox is the richest and the most challenging problem for the entire field of astrobiology and the Search for ExtraTerrestrial Intelligence (SETI) studies. This book shows how Fermi's paradox is intricately connected with many fields of learning, technology, arts, and even everyday life. It aims to establish the strongest possible version of the problem, to dispel many related confusions, obfuscations, and prejudices, as well as to offer a novel point of entry to the many solutions proposed in existing literature. Cirkovic argues that any evolutionary worldview cannot avoid resolving the Great Silence problem in one guise or another.

    For the past few years, disasters like earthquakes, landslides, mudslides, tsunamis, and traffic accidents have occurred with an ever-growing frequency, coverage, and intensity greatly beyond the expectation of the public. In order to respond effectively to disasters and to reduce casualties and property damage, countries around the world have invested more efforts in the theoretical study of emergency medicine and the construction of emergency medical rescue forces. Consequently, emergency medical rescue teams of all scales and types have come into being and have played significant roles in disaster response work. As the only state-level emergency medical rescue force from the Chinese People's Armed Police Forces, the force described here has developed, through continuous learning and practice, a characteristic mode in terms of grouping methods, equipment system construction, and training.

    The western Amazon continues to be an active and controversial zone of hydrocarbon exploration and production. We argue for the urgent need to implement best practices to reduce the negative environmental and social impacts associated with the sector. Here, we present a three-part study aimed at resolving the major obstacles impeding the advancement of best practice in the region. Our focus is on Loreto, Peru, one of the largest and most dynamic hydrocarbon zones in the Amazon. First, we develop a set of specific best practice guidelines to address the lack of clarity surrounding the issue. These guidelines incorporate both engineering-based criteria and key ecological and social factors. Second, we provide a detailed analysis of existing and planned hydrocarbon activities and infrastructure, overcoming the lack of information that typically hampers large-scale impact analysis. Third, we evaluate the planned activities and infrastructure with respect to the best practice guidelines. We show that Loreto is an extremely active hydrocarbon front, highlighted by a number of recent oil and gas discoveries and a sustained government push for increased exploration. Our analyses reveal that the use of technical best practice could minimize future impacts by greatly reducing the amount of required infrastructure such as drilling platforms and access roads. We also document a critical need to consider more fully the ecological and social factors, as the vast majority of planned infrastructure overlaps sensitive areas such as protected areas, indigenous territories, and key ecosystems and watersheds. Lastly, our cost analysis indicates that following best practice does not impose substantially greater costs than conventional practice, and may in fact reduce overall costs. Barriers to the widespread implementation of best practice in the Amazon clearly exist, but our findings show that there can be great benefits to its implementation.

    Objective This retrospective study presents the long-term results of catheter-directed foam sclerotherapy of the great saphenous vein. Method From January 2003 to June 2017, 277 patients with varices and great saphenous vein incompetence were treated with echo-guided foam sclerotherapy. Forty-six patients were treated with long-catheters guided by foam sclerotherapy. Foaming was carried out with sodium-tetra-decyl-sulphate. Results Results were examined in the two groups: A (long-catheters) and B (other procedures). The median overall follow-up was 52.1 months. In the A-group, the complete occlusion rate was 34/46 pts (73.9%) and partial occlusion was 10/46 (21.7%). In the B-group, respectively, 130/231 (56.2%) and 90/231 (38.9%). Comparisons between groups were statistically significant (p = 0.023; p = 0.021). Failures involved, respectively, 2/46 (4.3%) and 11/231 (4.7%) with no statistical significance. The complication rates were similar in the two groups. Conclusions In this long-term experience (median follow-up exceeding four years), foam-guided sclerotherapy of the great saphenous vein with a long-catheter turned out to be more effective than the usual foam-guided sclerotherapy.

    Caffeine has relevance for women's health and pregnancy, including significant associations with spontaneous abortion and low birth weight. According to scientific data, pregnant women and women of reproductive age should be advised to limit their caffeine consumption. This article reviews the implications of caffeine for women's psychological and physical health, and presents data on obstetrician-gynecologists' (ob-gyns) knowledge and practices pertaining to caffeine. Ob-gyns (N = 386) who are members of the American College of Obstetricians and Gynecologists' Collaborative Ambulatory Research Network responded to a 21-item survey about caffeine. Although most knew that caffeine is passed through breast milk, only 24.8% were aware that caffeine metabolism significantly slows as pregnancy progresses. Many respondents were not aware of the caffeine content of commonly used products, such as espresso and Diet Coke, with 14.3% and 57.8% indicating amounts within an accurate range, respectively. Furthermore, ob-gyns did not take into account large differences in caffeine content across different caffeinated beverages with most recommending one to two servings of coffee or tea or soft drinks per day. There was substantial inconsistency in what was considered to be "high levels" of maternal caffeine consumption, with only 31.6% providing a response. When asked to indicate the risk that high levels of caffeine have on various pregnancy outcomes, responses were not consistent with scientific data. For example, respondents overestimated the relative risk of stillbirths and underestimated the relative risk of spontaneous abortion. There was great variability in assessment and advice practices pertaining to caffeine. More than half advise their pregnant patients to consume caffeine under certain circumstances, most commonly to alleviate headache and caffeine withdrawal. The data suggest that ob-gyns could benefit from information about caffeine and its relevance to their

    Great earthquakes (having seismic magnitudes of at least 8) usually involve abrupt sliding of rock masses at a boundary between tectonic plates. Such interplate ruptures produce dynamic and static stress changes that can activate nearby intraplate aftershocks, as is commonly observed in the trench-slope region seaward of a great subduction zone thrust event1-4. The earthquake sequence addressed here involves a rare instance in which a great trench-slope intraplate earthquake triggered extensive interplate faulting, reversing the typical pattern and broadly expanding the seismic and tsunami hazard. On 29 September 2009, within two minutes of the initiation of a normal faulting event with moment magnitude 8.1 in the outer trench-slope at the northern end of the Tonga subduction zone, two major interplate underthrusting subevents (both with moment magnitude 7.8), with total moment equal to a second great earthquake of moment magnitude 8.0, ruptured the nearby subduction zone megathrust. The collective faulting produced tsunami waves with localized regions of about 12metres run-up that claimed 192 lives in Samoa, American Samoa and Tonga. Overlap of the seismic signals obscured the fact that distinct faults separated by more than 50km had ruptured with different geometries, with the triggered thrust faulting only being revealed by detailed seismic wave analyses. Extensive interplate and intraplate aftershock activity was activated over a large region of the northern Tonga subduction zone. ?? 2010 Macmillan Publishers Limited. All rights reserved.

    Full Text Available The concept of "public accountability" is a challenge for political science as a new concept in this area in full debate and developement ,both in theory and practice. This paper is a theoretical approach of displaying some definitions, relevant meanings and significance odf the concept in political science. The importance of this concept is that although originally it was used as a tool to improve effectiveness and eficiency of public governance, it has gradually become a purpose it itself. "Accountability" has become an image of good governance first in the United States of America then in the European Union.Nevertheless,the concept is vaguely defined and provides ambiguous images of good governance.This paper begins with the presentation of some general meanings of the concept as they emerge from specialized dictionaries and ancyclopaedies and continues with the meanings developed in political science. The concept of "public accontability" is rooted in economics and management literature,becoming increasingly relevant in today's political science both in theory and discourse as well as in practice in formulating and evaluating public policies. A first conclusin that emerges from, the analysis of the evolution of this term is that it requires a conceptual clarification in political science. A clear definition will then enable an appropriate model of proving the system of public accountability in formulating and assessing public policies, in order to implement a system of assessment and monitoring thereof.

    Full Text Available The practical classes in the teaching of biochemistry could provide great contributions to the process of teaching and learning, and the understanding of these by students depend on, generally,  previous concepts about the experiment and procedures performed. It is presented in this paper the educational software protVirt, which could be used as a pedagogical innovation in the method of practical classes involving dosage of proteins, focusing on the development of skills for understanding the activities. The software was developed in Adobe Flash, with the possibility of online or offline use. Despite the possibilities of using protVirt in various modalities of education, highlights the use in online courses, in which students develop, commonly, the practical class without the teacher centers, accompanied by monitors and tutors.

    Many biotic and abiotic parameters affect the metabolites involved in the organoleptic and health value of fruits. It is therefore important to understand how the growers' decisions for cultivar and orchard management can affect the fruit composition. Practices, cultivars and/or year all might participate to determine fruit composition. To hierarchize these factors, fruit weight, dry matter, soluble solids contents, titratable acidity, individual sugars and organics acids, and phenolics were measured in three apple cultivars (‘Ariane’, ‘Melrose’ and ‘Smoothee’) managed under organic, low-input and conventional management. Apples were harvested at commercial maturity in the orchards of the cropping system experiment BioREco at INRA Gotheron (Drôme, 26) over the course of three years (2011, 2012 and 2013). The main factors affecting primary and secondary metabolites, in both apple skin and flesh, were by far the cultivar and the yearly conditions, while the management system had a very limited effect. When considering the three cultivars and the year 2011 to investigate the effect of the management system per se, only few compounds differed significantly between the three systems and in particular the total phenolic content did not differ significantly between systems. Finally, when considering orchards grown in the same pedoclimatic conditions and of the same age, instead of the usual organic vs. conventional comparison, the effect of the management system on the apple fruit quality (Fruit weight, dry matter, soluble solids content, titratable acidity, individual sugars, organic acids, and phenolics) was very limited to non-significant. The main factors of variation were the cultivar and the year of cropping rather than the cropping system. More generally, as each management system (e.g. conventional, organic…) encompasses a great variability of practices, this highlights the importance of accurately documenting orchard practices and design beside the

    Some hope is returning for recovery of the fish stocks of the Great Lakes, which have been outstanding examples of abuse although they are the world's largest and most valuable freshwater fishery resource. The lakes and the fish in them have been under complete jurisdiction of sovereign nations and their subdivisions almost since the settlement of north-central North America, but ironically this control has not prevented their decadence. For the first time in the long history of the Great Lakes fishery, management measures have been taken to meliorate conditions that contributed to earlier difficulties.

  13. Oil and the geopolitics of Central Asia: A "new 'great game'"?

    Science.gov (United States)

    Al-Sati, Saud M.

    The nineteenth century rivalry between the Russian Empire and Great Britain over Central Asia, known as the "great game," was triggered by the quest for power and dominance. This study revisits Sir Halford Mackinder's thesis, which viewed the "heartland," consisting of Russia and Central Asia, as being crucial for international politics. It also discusses the influence of Mackinder's ideas on twentieth century geopolitical thinking. The study also examines the common assumption that the new "great game" in Central Asia is evolving around the exploitation of energy resources, and analyzes the consequences of this new factor for the geopolitical significance of the region. The landlocked nature of the Central Asian countries makes it necessary for them to rely on their neighbors for the export of oil and gas to international markets. Thus, the political and economic interests of Russia, Iran, and Turkey motivate them to compete with each other for export routes through their territories. This study also shows that the estimates of Central Asian proven oil reserves are characterized by considerable ambiguity. Estimates vary from seven to twenty-two billion barrels. Despite the fact that these proven oil reserves are limited compared to those of other regions, such as the Middle East, continued exploration is compatible with the Western strategy of energy resource diversification. Another primary aim of American involvement is to prevent the reintegration of Central Asia into the Russian federation and to block Chinese influence in Central Asia. This study reveals that realities in today's Central Asia are different from those of the nineteenth century. Central Asia now consists of independent countries; the competing powers have changed, with the exception of Russia; and oil has emerged as a new factor. However, the perpetual quest for power and dominance that marked the historical "great game" is still at work in the last decade of the twentieth century. Finally, the

    Full Text Available Background: Primary health care has undergone great changes as a consequence of demographic changes, growing patients’ awareness and organizational changes in the healthcare system. Declining interest in family medicine specialization further worsens the situation. In the period of lack of GPs and their overloading, it is necessary to include a diploma graduate nurse in the team of GPs and to define competencies and activities in such a way that encourage more active approach to the patients, meeting the indicators of quality.The purpose of the article is to describe the project of model practice in Slovenia and to present some results.Methods: A model practice introduces a new concept in the areas of human resource standards (to existing team, a diploma graduate nurse is included on a part-time basis; work competences (use of protocols for the treatment of chronic patients, extended and well-defined preventive screenings, establishing registers of chronic patients and assessing quality by means of quality indicators and work management (redistribution of workload .Results: Due to great interest of general practitioners, a total of 271 model practices were introduced in 2011 and 2012. MPs have been distributed evenly through different regions inSlovenia. Registers of patients with chronic diseases (COPD, asthma and diabetes have been established and during the preventive screening, on average 2 patients with a chronic disease and 15 patients with risk factors have been detected. Patients are treated actively according to their needs rather than their preferences.Conclusions: The project of MPs enables a high quality and cost effectiveness of patients’ treatment in family medicine. With a gradual introducing of new MPs, a well planed and monitored patients’ care will be implemented in the practice. In a long run, disburdening of a secondary care level and more rational consumption of drugs are expected

    Full Text Available Arterial sclerosis has been extensively described but reports on venous sclerosis are very sparse. Phlebosclerosis refers to the thickening and hardening of the venous wall. Despite its morphological similarities with arteriosclerosis and potential morbid consequences, phlebosclerosis has gained only little attention. We report a 72 year old male with paralysis and atrophy of the right leg due to childhood poliomyelitis who was referred for coronary artery bypass surgery. The great saphenous vein, harvested from the left leg, showed a hardened cord-like obliterated vein. Surprisingly, harvested veins from the atrophic limb were normal and successfully used for grafting.

    A common problem of some information technology courses is the difficulty of providing practical exercises. Although different approaches have been followed to solve this problem, it is still an open issue, specially in security and computer network courses. This paper proposes NETinVM, a tool based on nested virtualization that includes a fully functional lab, comprising several computers and networks, in a single virtual machine. It also analyzes and evaluates how it has been used in different teaching environments. The results show that this tool makes it possible to perform demos, labs and practical exercises, greatly appreciated by the students, that would otherwise be unfeasible. Also, its portability allows to reproduce classroom activities, as well as the students' autonomous work.

    2005-05-01

    Although many native mollusc populations have been eliminated in the Laurentian Great Lakes by the exotic zebra mussel, recent surveys have found abundant unionid (Bivalvia: Unionidae) populations in some coastal wetlands. Unionid burrowing in soft sediments and predation by fish have been shown to reduce numbers of attached zebra mussels, and we tested these factors in a Lake Erie coastal wetland. In 2002, we held live unionids (Leptodea fragilis, Quadrula quadrula) and Pyganodon grandis shells in exclosures with wire mesh bottoms that were buried to sediment depths of either 5, 10, or 20 cm. After 2 months, numbers of attached dreissenids on unionids were significantly higher inside all exclosure treatments than outside exclosures. This indicated that either unionid burrowing was prevented in all sediment depth treatments or molluscivores were excluded by exclosures. In 2004, we measured dreissenid colonization on Q. quadrula and PVC plates in bottomless exclosures with different mesh sizes. After 6 months, dreissenid numbers on PVC plates and on Q. quadrula in 2.5 cm X 2.5 cm and 5 cm X 10 cm mesh exclosures were significantly higher than in open exclosures. These data suggest that molluscivores are important in limiting dreissenids in Great Lake coastal wetlands.

  1. Management and non-supervisory perceptions surrounding the implementation and significance of high-performance work practices in a nuclear power plant

    Science.gov (United States)

    Ashbridge, Gayle Ann

    Change management has become an imperative for organizations as they move into the 21st century; up to 75 percent of change initiatives fail. Nuclear power plants face the same challenges as industrial firms with the added challenge of deregulation. Faced with this challenge, restructuring the electric utility has raised a number of complex issues. Under traditional cost-of-service regulation, electric utilities were able to pass on their costs to consumers who absorbed them. In the new competitive environment, customers will now choose their suppliers based on the most competitive price. The purpose of this study is to determine the degree of congruence between non-supervisory and supervisory personnel regarding the perceived implementation of high performance workplace practices at a nuclear power plant. This study used as its foundation the practices identified in the Road to High Performance Workplaces: A Guide to Better Jobs and Better Business Results by the U.S. Department of Labor's Office of the American Workplace (1994). The population for this study consisted of organizational members at one nuclear power plant. Over 300 individuals completed surveys on high performance workplace practices. Two surveys were administered, one to non-supervisory personnel and one to first line supervisors and above. The determination of implementation levels was accomplished through descriptive statistical analysis. Results of the study revealed 32 areas of noncongruence between non-supervisory and supervisory personnel in regard to the perceived implementation level of the high performance workplace practices. Factor analysis further revealed that the order in which the respondents place emphasis on the variables varies between the two groups. This study provides recommendations that may improve the nuclear power plants alignment of activities. Recommendations are also provided for additional research on high-performance work practices.

    This study examines the changes in health care utilization for mental health disorders among patients who were diagnosed with depressive and/or anxiety disorders during the Great Recession 2007-2009 in the USA. Negative binomial regressions are used to estimate the association of the economic recession and mental health care use for females and males separately. Results show that prescription drug utilization (e.g., antidepressants, psychotropic medications) increased significantly during the economic recession 2007-2009 for both females and males. Physician visits for mental health disorders decreased during the same period. Results show that racial disparities in mental health care might have increased, while ethnic disparities persisted during the Great Recession. Future research should separately examine mental health care utilization by gender and race/ethnicity.

    Heart disease is the fifth most common cause of death in infants and children (preceded by anoxic and hypoxic conditions, gross congenital malformations, accidental death, and immaturity). Of all the cardiac lesions, congenital heart disease (CHD) makes up the gross majority, accounting for approximately 90% of all cardiac deaths. Approximately two-thirds of all infants who die from CHD do so within the first year of life; of these, approximately one-third die within the first month. The most common cause of death in the first month is hypoplastic left heart syndrome and lesions associated with it, i.e., aortic atresia/critical aortic stenosis and mitral atresia/critical mitral stenosis. Severe coarctation of the aorta (coarctation syndrome) and transposition of the great arteries are the other most important causes of death in this age group. CHD occurs as a familial condition in approximately 1-4% of cases; ventricular septal defects, patent ductus arteriosus, and atrial septal defect are particularly common forms. Parental age plays an important role, with a significantly increased risk of CHD in infants of mothers over 39 years of age. Patent ductus arteriosus is more prevalent in firstborn children, particularly those born prematurely to young mothers. Environmental factors, such as exposure to teratogenic agents, have also been shown to increase the incidence of CHD. Children with various syndromes also have increased incidence of CHD. Down syndrome is a classic example, as are other trisomies

    2017-01-01

    Full Text Available The article revises an established view of Russian Revolution as two separate events - February Revolution and October Revolution. The author supports the concept of the «Great Russian Revolution», which unites these two events in a single process of revolutionary development. The author draws attention to the following advantages of the concept under consideration. First, it conceptualizes the revolution as a process contingent of a local and global historical context. In this sense, the revolution is presented as the transition of society to the modern stage of development, meaning the transition to modernity. Second, revolutionary events in Russia are considered from the point of view of the evolution of the spatial and socioeconomic distribution and rearrangement of key social groups: peasantry, elites, national and ethnic minorities. Third, it takes into account the personal factor in the revolutionary events, the influence of individual personalities on escalation or the reduction of socio-political tensions. Fourth, it draws attention to the fact that revolutions imply the use of various forms of political violence. Each revolution is characterized by a unique correlation of forms and intensity of political violence. Finally, it gives a normative assessment of the Revolution, encouraging a national discussion on the results and consequences of this great event.

    2011-01-01

    Unless you have flown over the region or seen aerial photographs, it is hard to grasp the scale of the millions of lakes and wetlands that dot the prairie landscape of the glaciated Northern Great Plains (Figure 1). This region of abundant aquatic habitats within a grassland matrix provides for the needs of a wide diversity of wildlife species and has appropriately been deemed the "duck factory of North America." While the sheer number of lakes and wetlands within this area of the Northern Great Plains can be truly awe-inspiring, their diversity in terms of the chemical composition of their water adds an equally important component supporting biotic diversity and productivity. Water within these lakes and wetlands can range from extremely fresh with salinities approaching that of rainwater to hypersaline with salinity ten times greater than that of seawater. Additionally, while variation in salinity among these water bodies can be great, the ionic composition of lakes and wetlands with similar salinities can vary markedly, influencing the overall spatial and temporal diversity of the region's biota.

    Full Text Available Construction waste management (CWM has received worldwide attention for some time. As a result, a plethora of research, investigating a wide array of CWM issues such as their profiles, practices, and performance, has been reported in individual economies around the globe. However, a cross-jurisdictional comparison of these issues is limitedly presented in the literature despite its importance to benchmarking performance and identifying best CWM practices in the context of globalization whereby knowledge sharing has already transcended traditional country boundaries. The aim of this ex post facto research is to compare CWM profiles, practices, and performance in Australia, Europe (Europe refers to EU-27 member countries in the European Union, including Belgium, France, Germany, Italy, Luxembourg, Netherlands, Denmark, Great Britain, Ireland, Portugal, Spain, Greece, Austria, Finland, Sweden, Czech Republic, Estonia, Hungary, Latvia, Lithuania, Poland, Slovakia, Slovenia, Malta, Cyprus, Bulgaria, and Romania., Hong Kong, and the United Kingdom at a national-level, with a view to facilitating CWM knowledge sharing internationally. It does so by triangulating empirical data collected from various national statistical yearbooks with research papers and professional reports on CWM in these economies. It is found that in producing one million (US dollars’ work, construction contributes a volume of solid waste ranging from 28 to 121 tons among countries. Conscientious CWM practices can make a significant difference in reducing, reusing, or recycling construction waste, as evident in the large variation in the CWM performance. While it might be oversimplified to conclude that the best practices in one country can be applied in another, the research provides insightful references into sharing CWM knowledge across boundaries.

    2010-03-01

    Europe, because of its geographical location, strategic position on trade routes, and colonial past, has a long history of caring for travellers' health. Within Europe, there is great diversity in the practice of travel medicine. Some countries have travel medicine societies and provisions for a periodic distribution of recommendations, but many countries have no national pre-travel guidelines and follow international recommendations such as those provided by the WHO. Providers of travel medicine include tropical medicine specialists, general practice nurses and physicians, specialist 'travel clinics', occupational physicians, and pharmacists. One of the core functions of the European Centre for Disease Prevention and Control-funded network of travel and tropical medicine professionals, EuroTravNet, is to document the status quo of travel medicine in Europe. A three-pronged approach is used, with a real-time online questionnaire, a structured interview with experts in each country, and web searching.

    Despite published guidelines on Peyronie's disease (PD), there are limited data on actual surgical practice among surgeons. To evaluate the surgical practice patterns in PD among surgeons from different continents and members of various sexual medicine societies. An anonymous survey on various pre-, intra-, and postoperative aspects of PD surgical care was distributed in printed format during International Society of Sexual Medicine meetings and as an online survey to International Society of Sexual Medicine members. 390 surgeons responded to the survey, with great variations in pre-, intra-, and postoperative strategies in PD surgical care. Most surgeons performed fewer than 10 penile plications and 10 graft surgeries per year. Modified Nesbit plication was the preferred option by most surgeons. Surgeons who received fellowship training were more likely to perform autologous than allograft surgery (odds ratio = 1.79, 95% CI = 1.13-2.82, P = .01). The use of penile color duplex ultrasound was inconsistently performed, with higher-volume surgeons (ie, >20 cases operated a year) more likely to use this diagnostic modality (odds ratio = 70.18, 95% CI = 20.99-234.6, P worldwide survey study has the potential to assist in the formation of a new practice guideline and serve as the basis for future prospective multinational studies. This is one of the largest surveys on PD practice and, to our knowledge, the only survey conducted across various sexual medicine societies, with the inclusion of many high-volume and experienced PD surgeons. This also is the 1st study to comprehensively evaluate many key aspects in surgical practice patterns for PD. However, the categorization on the questionnaire used in this survey was not designed to allow for direct comparison given the possibility of some surgeons with dual society memberships, reporting biases, large CIs in outcomes, different patient demographics, and cultural acceptance. There is great variation in surgical

  13. Assessing Canadian inventories to understand the environmental impacts of mercury releases to the Great Lakes region

    International Nuclear Information System (INIS)

    Trip, Luke; Bender, Tonya; Niemi, David

    2004-01-01

    North American pollutant release and transfer registries have been continuously developing with an eye to understanding source/receptor relationships and ensuring that the polluter-paid principle is applied to the appropriate parties. The potential contribution of mercury to the Great Lakes Basin arising from the rerelease of historic mercury pollution from contaminated aquatic and terrestrial media is poorly understood and the subject of concern. Although a considerable amount of data may be available on the atmospheric component of mercury releases to the Basin, further inventory work is needed to quantify the rerelease of the historic mercury. Much of the related existing inventory information is either not derived from direct measurement or not bounded by a mass-balance accounting. Critical to this determination is an increased confidence in the inventories of mercury from past and current practices. This may be enhanced through comprehensive and thorough surveys of contributions from specific products and their life-cycle assessments. An even greater challenge is to determine the bioavailability of the mercury emanating from land-based sources and from aquatic media. This paper describes the interplay among the sources and receptors of mercury and provides a quantitative assessment of current Canadian contributions of mercury as a contaminant to the Great Lakes. Recommendations for improved assessments are provided

  14. Factors contributing to record-breaking heat waves over the Great Plains during the 1930s Dust Bowl

    Cowan, T.; Hegerl, G. C.

    2016-12-01

    Record-breaking summer heat waves that plagued contiguous United States in the 1930s emerged during the decade-long "Dust Bowl" drought. Using high-quality daily temperature observations, the Dust Bowl heat wave characteristics for the Great Plains are assessed using metrics that describe variations in heat wave activity and intensity. We also quantify record-breaking heat waves over the pre-industrial period for 22 CMIP5 model multi-century realisations. The most extreme Great Plains heat wave summers in the Dust Bowl decade (e.g. 1931, 1934, 1936) were pre-conditioned by anomalously dry springs, as measured by proxy drought indices. In general, summer heat waves over the Great Plains develop 15-20 days earlier after anomalously dry springs, and are also significantly longer and hotter, indicative of the importance of land surface feedbacks in heat wave intensification. The majority of pre-industrial climate model experiments capture regionally clustered summer heat waves across North America, although the North Pacific and Atlantic sea surface temperature patterns associated with the heat waves vary considerably between models. Sea surface temperature patterns may be more important for influencing winter and spring precipitation, thus amplifying summer heat waves during drought periods. The synoptic pattern that commonly appeared during the exceptional Dust Bowl heat waves featured an anomalous broad surface pressure ridge straddling an upper level blocking anticyclone over the western United States. This forced significant subsidence and adiabatic warming over the Great Plains, and triggered anomalous southward warm advection over southern regions, prolonging and amplifying the heat waves over central United States. Importantly, the results show that despite the sparsity of stations in the 1930s, homogeneous observations are crucial in accurately quantifying the Dust Bowl decade heat waves, as opposed to solely relying on atmospheric reanalysis.

    We use a novel enterprise survey to gauge the relationship between saving instruments and entrepreneurial reinvestment. We show that while most informal saving practices are not associated with a lower likelihood of reinvestment when compared with formal saving practices, there is a significantly

    Environmental legislation has reduced the anthropogenic loadings of Pb and Cd to the Great Lakes region over the past 3 decades. However, the accumulation rates of these metals still remain above background values. Because environmental legislation was targeted at major sources (e.g., Pb in gasoline) whose influence on the environment was on a regional scale, local sources (e.g., watershed scale) for the metals may now play a more significant role. The relative importance of regional versus local scale influences on metal inputs to the environment is poorly understood. In this study, sediment chronologies of Pb and Cd were examined from 12 inland lakes that cover the broad geographic area of the State of Michigan. These chronologies were compared temporally and spatially and to watershed population densities and metal production records to gain an understanding of local and regional influences on metal inputs to the Great Lakes region. Results show that anthropogenic Pb loading during the 1930s and 1970s was dominated by regional sources. such as coal burning and use of leaded gasoline. Current loadings are now more related to local influences such as watershed population densities, rather than atmospheric deposition. Anthropogenic Cd loadings to the Great Lakes region have been dominated by both regional and local sources over time. Lead may also have shown the influence of local sources over time, if the influence of emissions from gasoline had not been present. This work shows that Pb and Cd loadings in the Great Lakes region are strongly related to watershed population densities; however, the specific sources and pathways for the metal cycling are unclear.

    Full Text Available The Great Prespa region is situated in the Balkan Peninsula and is divided between Albania, Macedonia and Greece. It includes the Great Prespa Lake and the surrounding beach and meadow, areas designated for agricultural use and the towns of Pusteci (formerly known as Liqenas and Resen. This region is now part of the Trans-Boundary Biosphere Reserve ‘Ohrid-Prespa Watershed. Great and Small Prespa lakes plus Ohrid Lake are included in this newly-approved UNESCO world Heritage Site, but for this paper, we are looking only at the area surrounding the Great Prespa Lake. It is critical for this area to be protected immediately, because of the overuse it has undergone in recent years. While current levels of fauna are dangerously declining due to recent over-harvesting, this area has been known historically for its diverse natural and cultural features. Thus it is important to take drastic measures to reclaim the natural beauty immediately, including those areas currently covered by Prespa National Parks in Albania and Greece and Galichica and Pelisteri National Parks in Macedonia. Due to many wars over the centuries, it exists a mixture of Albanian and Macedonian culture. The historical and architectural remaining, religious structures and artifacts testify the richness and uniqueness of the communities of Pustec and Resen have. The cultural heritage is now a key element designated for the development of the region’s sustainable tourism development. This study was enhanced via the Geographic Info System (GIS digital presentation showing the opportunities for natural and cultural tourism in both countries (Albania and Macedonia.

    Great hornbills (Buceros bicornis) are a long-lived, monogamous species that forms strong pair-bonds, and mate compatibility is thought to be important for successful reproduction. Within AZA, great hornbills are listed as a red SSP. The population consists of a limited number of individuals that do not breed reliably, and improving reproduction is a top priority for the Coraciiformes TAG. To better understand mating behavior and evaluate mate compatibility, this study documented the behavior of pairs of great hornbills during and immediately after courtship. Using live observations, the study followed one female, an experienced and successful breeder, as she was paired with four successive males over 11 breeding seasons. Initially, males frequently vocalized, investigated the nest, and approached the female. As the female spent more time in the nest, these behaviors were replaced by regurgitation and food offering. The female was most often observed plastering and vocalizing. Behavioral differences between successful and unsuccessful pairs, possibly indicative of pair compatibility, included rates of approaching, billing, and biting. Numerous behaviors occurred more frequently during years that a chick hatched, including pseudoregurgitation, regurgitation, offering food items, and nest investigation. Males also spent more time in proximity to both the female and the nest during years that a chick hatched. Together, these results suggest that the amount of time pairs spend in proximity, the amount of time a male spends near the nest, and the frequency of certain behaviors may help evaluate compatibility and the likelihood of successful reproduction for pairs of great hornbills. © 2015 Wiley Periodicals, Inc.
