Effects of climate change on surface-water photochemistry: a review.

PubMed

De Laurentiis, Elisa; Minella, Marco; Maurino, Valter; Minero, Claudio; Vione, Davide

2014-10-01

Information concerning the link between surface-water photochemistry and climate is presently very scarce as only a few studies have been dedicated to the subject. On the basis of the limited knowledge that is currently available, the present inferences can be made as follows: (1) Warming can cause enhanced leaching of ionic solutes from the catchments to surface waters, including cations and more biologically labile anions such as sulphate. Preferential sulphate biodegradation followed by removal as organic sulphides in sediment could increase alkalinity, favouring the generation of the carbonate radical, CO3 (·-). However, this phenomenon would be easily offset by fluctuations of the dissolved organic carbon (DOC), which is strongly anticorrelated with CO3 (·-). Therefore, obtaining insight into DOC evolution is a key issue in understanding the link between photochemistry and climate. (2) Climate change could exacerbate water scarcity in the dry season in some regions. Fluctuations in the water column could deeply alter photochemistry that is usually favoured in shallower waters. However, the way water is lost would strongly affect the prevailing photoinduced processes. Water outflow without important changes in solute concentration would mostly favour reactions induced by the hydroxyl and carbonate radicals (·OH and CO3 (·-)). In contrast, evaporative concentration would enhance reactions mediated by singlet oxygen ((1)O2) and by the triplet states of chromophoric dissolved organic matter ((3)CDOM*). (3) In a warmer climate, the summer stratification period of lakes would last longer, thereby enhancing photochemical reactions in the epilimnion but at the same time keeping the hypolimnion water in the dark for longer periods.

Economic impacts and impact dynamics of Bt (Bacillus thuringiensis) cotton in India

Kathage, Jonas; Qaim, Matin

2012-01-01

Despite widespread adoption of genetically modified crops in many countries, heated controversies about their advantages and disadvantages continue. Especially for developing countries, there are concerns that genetically modified crops fail to benefit smallholder farmers and contribute to social and economic hardship. Many economic studies contradict this view, but most of them look at short-term impacts only, so that uncertainty about longer-term effects prevails. We address this shortcoming by analyzing economic impacts and impact dynamics of Bt cotton in India. Building on unique panel data collected between 2002 and 2008, and controlling for nonrandom selection bias in technology adoption, we show that Bt has caused a 24% increase in cotton yield per acre through reduced pest damage and a 50% gain in cotton profit among smallholders. These benefits are stable; there are even indications that they have increased over time. We further show that Bt cotton adoption has raised consumption expenditures, a common measure of household living standard, by 18% during the 2006–2008 period. We conclude that Bt cotton has created large and sustainable benefits, which contribute to positive economic and social development in India. PMID:22753493

Music in Research and Rehabilitation of Disorders of Consciousness: Psychological and Neurophysiological Foundations.

PubMed

Kotchoubey, Boris; Pavlov, Yuri G; Kleber, Boris

2015-01-01

According to a prevailing view, the visual system works by dissecting stimuli into primitives, whereas the auditory system processes simple and complex stimuli with their corresponding features in parallel. This makes musical stimulation particularly suitable for patients with disorders of consciousness (DoC), because the processing pathways related to complex stimulus features can be preserved even when those related to simple features are no longer available. An additional factor speaking in favor of musical stimulation in DoC is the low efficiency of visual stimulation due to prevalent maladies of vision or gaze fixation in DoC patients. Hearing disorders, in contrast, are much less frequent in DoC, which allows us to use auditory stimulation at various levels of complexity. The current paper overviews empirical data concerning the four main domains of brain functioning in DoC patients that musical stimulation can address: perception (e.g., pitch, timbre, and harmony), cognition (e.g., musical syntax and meaning), emotions, and motor functions. Music can approach basic levels of patients' self-consciousness, which may even exist when all higher-level cognitions are lost, whereas music induced emotions and rhythmic stimulation can affect the dopaminergic reward-system and activity in the motor system respectively, thus serving as a starting point for rehabilitation.

[The consolidation of memory, one century on].

PubMed

Prado-Alcala, R A; Quirarte, G L

The theory of memory consolidation, based on the work published by Georg Elias Muller and Alfons Pilzecker over a century ago, continues to guide research into the neurobiology of memory, either directly or indirectly. In their classic monographic work, they concluded that fixing memory requires the passage of time (consolidation) and that memory is vulnerable during this period of consolidation, as symptoms of amnesia appear when brain functioning is interfered with before the consolidation process is completed. Most of the experimental data concerning this phenomenon strongly support the theory. In this article we present a review of experiments that have made it possible to put forward a model that explains the amnesia produced in conventional learning conditions, as well as another model related to the protection of memory when the same instances of learning are submitted to a situation involving intensive training. Findings from relatively recent studies have shown that treatments that typically produce amnesia when they are administered immediately after a learning experience (during the period in which the memory would be consolidating itself) no longer have any effect when the instances of learning involve a relatively large number of trials or training sessions, or relatively high intensity aversive events. These results are not congruent with the prevailing theories about consolidation.

Emergent long-range synchronization of oscillating ecological populations without external forcing described by Ising universality

PubMed Central

Noble, Andrew E.; Machta, Jonathan; Hastings, Alan

2015-01-01

Understanding the synchronization of oscillations across space is fundamentally important to many scientific disciplines. In ecology, long-range synchronization of oscillations in spatial populations may elevate extinction risk and signal an impending catastrophe. The prevailing assumption is that synchronization on distances longer than the dispersal scale can only be due to environmental correlation (the Moran effect). In contrast, we show how long-range synchronization can emerge over distances much longer than the length scales of either dispersal or environmental correlation. In particular, we demonstrate that the transition from incoherence to long-range synchronization of two-cycle oscillations in noisy spatial population models is described by the Ising universality class of statistical physics. This result shows, in contrast to all previous work, how the Ising critical transition can emerge directly from the dynamics of ecological populations. PMID:25851364

[Knowledge and opinions concerning legal and ethical issues with abortion among physicians working in emergency wards in Ribeirão Preto, São Paulo, Brazil].

PubMed

Loureiro, David Câmara; Vieira, Elisabeth Meloni

2004-01-01

This study focused on the knowledge and opinions of physicians regarding legal and ethical aspects of abortion. A self-administered questionnaire was filled out by 57 physicians working in the emergency rooms of two hospitals in Ribeirão Preto, São Paulo State, Brazil in 2001. The questionnaire had 38 questions on general knowledge, legislation, and attitudes towards abortion. Interviewees' mean age was 28.3, most were females, 52.6% were single, 42.1% were married, 54.4% were Catholic, and 21% were Spiritists. Although most of the physicians had a good level of overall knowledge on abortion (70%), one in five was not aware that abortion is the main cause of maternal mortality in Brazil. Most accepted the prevailing legal conditions for performing an abortion in Brazil but would also include fetal malformation incompatible with life, while opposing decriminalization of abortion on other grounds. Limited knowledge is revealed by misconceptions concerning enforcement of the prevailing legislation in practice. The study strongly suggests that many physicians lack knowledge or face difficulties in conforming to the Brazilian legislation on abortion.

Court-mediated disputes between physicians and families over the medical care of children.

To describe the judiciary's approach to parent-physician disputes over the care of sick children. Court publications. Fifty parent-physician disagreements over the care of children led to physician requests for court intervention and resulted in judicial opinions published by the court. The opinions describe 66 children from 20 states. Physicians prevailed at the initial decision in 44 (88%) of the 50 disputes and at the final decision in 40 disputes (80%). Physicians were more likely to prevail in religion-based disputes than in other cases (27 of 30 vs 13 of 20; P<.03), but they were less likely to prevail in disputes concerning life-threatening or potentially disabling conditions (23 of 31 vs 17 of 19; P<.19). Courts acknowledged the pediatric patients' views in only 10 of the disputes (9 of the 19 cases involving adolescents and 1 of the 31 cases involving children younger than 12 years). For most courts, the petitioning physicians provided the only source of scientific information. Published court opinions create precedents for future decisions and provide insight into the consequences of seeking court intervention for the physician who encounters parental refusal of care.

The article presents the analysis of the occurrence of diabetes mellitus-linked sight impairment and proliferative retinopathy after data of National Diabetes Population Register among patients receiving insulin therapy. The number of women with above mentioned impairments has been found to prevail significantly over that of men. This tendency is also observed among the patients aged to 50 y. o., although in this age group the number of men with diabetes mellitus prevails over that of women. This discrepancy can be explained through higher death rate linked with diabetes mellitus among men as compared with women. Death rate statistics concerning patients with diabetes mellitus complicated with sight impairment for 2003 y. confirms this supposition.

Enzalutamide significantly improved radiographic progression-free survival (rPFS) and overall survival (OS) among men with chemotherapy-naïve metastatic castration-resistant prostate cancer at the prespecified interim analysis of PREVAIL, a phase 3, double-blind, randomized study. We evaluated the longer-term efficacy and safety of enzalutamide up to the prespecified number of deaths in the final analysis, which included an additional 20 mo of follow-up for investigator-assessed rPFS, 9 mo of follow-up for OS, and 4 mo of follow-up for safety. Enzalutamide reduced the risk of radiographic progression or death by 68% (hazard ratio [HR] 0.32, 95% confidence interval [CI] 0.28–0.37; p < 0.0001) and the risk of death by 23% (HR 0.77, 95% CI 0.67–0.88; p = 0.0002). Median investigator-assessed rPFS was 20.0 mo (95% CI 18.9–22.1) in the enzalutamide arm and 5.4 mo (95% CI 4.1–5.6) in the placebo arm. Median OS was 35.3 mo (95% CI 32.2–not yet reached) in the enzalutamide arm and 31.3 mo (95% CI 28.8–34.2) in the placebo arm. At the time of the OS analysis, 167 patients in the placebo arm had crossed over to receive enzalutamide. The most common adverse events in the enzalutamide arm were fatigue, back pain, constipation, and arthralgia. This final analysis of PREVAIL provides more complete assessment of the clinical benefit of enzalutamide. PMID:27477525

Plasticity-mediated collapse and recrystallization in hollow copper nanowires: a molecular dynamics simulation.

PubMed

Dutta, Amlan; Raychaudhuri, Arup Kumar; Saha-Dasgupta, Tanusri

2016-01-01

We study the thermal stability of hollow copper nanowires using molecular dynamics simulation. We find that the plasticity-mediated structural evolution leads to transformation of the initial hollow structure to a solid wire. The process involves three distinct stages, namely, collapse, recrystallization and slow recovery. We calculate the time scales associated with different stages of the evolution process. Our findings suggest a plasticity-mediated mechanism of collapse and recrystallization. This contradicts the prevailing notion of diffusion driven transport of vacancies from the interior to outer surface being responsible for collapse, which would involve much longer time scales as compared to the plasticity-based mechanism.

Strangers or Friends?

PubMed Central

Curlin, Farr A; Hall, Daniel E

2005-01-01

We argue that debate regarding whether and how physicians should engage religious concerns has proceeded under inadequate terms. The prevailing paradigm approaches dialogue regarding religion as a form of therapeutic technique, engaged by one stranger, the physician, upon another stranger, the patient. This stranger-technique framework focuses the debate on questions of physicians' competence, threats to patients' autonomy, and neutrality regarding religion, and in so doing, it too greatly circumscribes the scope of physician-patient dialogue. In contrast, we argue that dialogue regarding religion is better approached as a form of philosophical discourse about ultimate human concerns. Such moral discourse is often essential to the patient-physician relationship, and rather than shrinking from such discourse, physicians might engage patients regarding religious concerns guided by an ethic of moral friendship that seeks the patient's good through wisdom, candor, and respect.

2012-09-15

It remains undefined if transradial coronary angiography from a right or left radial arterial approach differs in real-world practice. To address this issue, we performed a subanalysis of the PREVAIL study. The PREVAIL study was a prospective, multicenter, observational survey of unselected consecutive patients undergoing invasive cardiovascular procedures over a 1-month observation period, specifically aimed at assessing the outcomes of radial approach in the contemporary real world. The choice of arterial approach was left to the discretion of the operator. Prespecified end points of this subanalysis were procedural characteristics. Of 1,052 patients consecutively enrolled, 509 patients underwent transradial catheterization, 304 with a right radial and 205 with a left radial approach. Procedural success rates were similar between the 2 groups. Compared to the left radial group, the right radial group had longer procedure duration (46 ± 29 vs 33 ± 24 minutes, p <0.0001) and fluoroscopy time (765 ± 787 vs 533 ± 502, p <0.0001). At multivariate analysis, including a parsimonious propensity score for the choice of left radial approach, duration of procedure (beta coefficient 11.38, p <0.001) and total dose-area product (beta coefficient 11.38, p <0.001) were independently associated with the choice of the left radial artery approach. The operator's proficiency in right/left radial approach did not influence study results. In conclusion, right and left radial approaches are feasible and effective to perform percutaneous procedures. In the contemporary real world, however, the left radial route is associated with shorter procedures and lower radiologic exposure than the right radial approach, independently of an operator's proficiency.

The protean toxicities of lead: new chapters in a familiar story.

PubMed

Bellinger, David C

2011-07-01

Many times in the history of lead toxicology the view that "the problem" has been solved and is no longer a major health concern has prevailed, only to have further research demonstrate the prematurity of this judgment. In the last decade, an extraordinary amount of new research on lead has illustrated, all too clearly, that "the problem" has not disappeared, and that, in fact, it has dimensions never before considered. Recent risk assessments have concluded that research has yet to identify a threshold level below which lead can be considered "safe." Although children's intelligence has traditionally been considered to be the most sensitive endpoint, and used as the basis for risk assessment and standard setting, increased lead exposure has been associated with a wide variety of other morbidities both in children and adults, in some cases at biomarker levels comparable to those associated with IQ deficits in children. In adults, these endpoints include all-cause mortality and dysfunctions in the renal, cardiovascular, reproductive, central nervous systems. In children, IQ deficits are observed at blood lead levels well below 10 μg/dL, and the dose-effect relationship appears to be supra-linear. Other health endpoints associated with greater early-life lead exposure in children include ADHD, conduct disorder, aggression and delinquency, impaired dental health, and delayed sexual maturation. Studies employing neuroimaging modalities such as volumetric, diffusion tensor, and functional MRI are providing insights into the neural bases of the cognitive impairments associated with greater lead exposure.

Jumping the gun: the problematic discourse on socioeconomic status and cardiovascular health in India.

PubMed

2013-10-01

There has been an increased focus on non-communicable diseases (NCDs) in India, especially on cardiovascular diseases and associated risk factors. In this essay, we scrutinize the prevailing narrative that cardiovascular risk factors (CVRF) and cardiovascular disease (CVD) are no longer confined to the economically advantaged groups but are an increasing burden among the poor in India. We conducted a comprehensive review of studies reporting the association between socioeconomic status (SES) and CVRF, CVD, and CVD-related mortality in India. With the exception of smoking and low fruit and vegetable intake, the studies clearly suggest that CVRF/CVD is more prevalent among high SES groups in India than among the low SES groups. Although CVD-related mortality rates appear to be higher among the lower SES groups, the proportion of deaths from CVD-related causes was found to be greatest among higher SES groups. The studies on SES and CVRF/CVD also reveal a substantial discrepancy between the data presented and the authors' interpretations and conclusions, along with an unsubstantiated claim that a reversal in the positive SES-CVRF/CVD association has occurred or is occurring in India. We conclude our essay by emphasizing the need to prioritize public health policies that are focused on the health concerns of the majority of the Indian population. Resource allocation in the context of efforts to make health care in India free and universal should reflect the proportional burden of disease on different population groups if it is not to entrench inequity.

National differences in environmental concern and performance are predicted by country age.

PubMed

Hershfield, Hal E; Bang, H Min; Weber, Elke U

2014-01-01

There are obvious economic predictors of ability and willingness to invest in environmental sustainability. Yet, given that environmental decisions represent trade-offs between present sacrifices and uncertain future benefits, psychological factors may also play a role in country-level environmental behavior. Gott's principle suggests that citizens may use perceptions of their country's age to predict its future continuation, with longer pasts predicting longer futures. Using country- and individual-level analyses, we examined whether longer perceived pasts result in longer perceived futures, which in turn motivate concern for continued environmental quality. Study 1 found that older countries scored higher on an environmental performance index, even when the analysis controlled for country-level differences in gross domestic product and governance. Study 2 showed that when the United States was framed as an old country (vs. a young one), participants were willing to donate more money to an environmental organization. The findings suggest that framing a country as a long-standing entity may effectively prompt proenvironmental behavior.

The Egyptian state was formed prior to the existence of verifiable historical records. Conventional dates for its formation are based on the relative ordering of artefacts. This approach is no longer considered sufficient for cogent historical analysis. Here, we produce an absolute chronology for Early Egypt by combining radiocarbon and archaeological evidence within a Bayesian paradigm. Our data cover the full trajectory of Egyptian state formation and indicate that the process occurred more rapidly than previously thought. We provide a timeline for the First Dynasty of Egypt of generational-scale resolution that concurs with prevailing archaeological analysis and produce a chronometric date for the foundation of Egypt that distinguishes between historical estimates.

Plasticity-mediated collapse and recrystallization in hollow copper nanowires: a molecular dynamics simulation

PubMed Central

Raychaudhuri, Arup Kumar; Saha-Dasgupta, Tanusri

2016-01-01

Summary We study the thermal stability of hollow copper nanowires using molecular dynamics simulation. We find that the plasticity-mediated structural evolution leads to transformation of the initial hollow structure to a solid wire. The process involves three distinct stages, namely, collapse, recrystallization and slow recovery. We calculate the time scales associated with different stages of the evolution process. Our findings suggest a plasticity-mediated mechanism of collapse and recrystallization. This contradicts the prevailing notion of diffusion driven transport of vacancies from the interior to outer surface being responsible for collapse, which would involve much longer time scales as compared to the plasticity-based mechanism.

The turbulent state of health care and the rapid changes that show no sign of abating point to many career-related challenges for physician executives. How can you predict the impact of these changes on your career? What measures can be taken to prevent any negative impact of change? And how can you prevail when dealt a negative blow like job loss? The signs that foreshadow the unraveling of a physician executive's career are described. The warning signs are: Not keeping up with change, losing your influence; getting negative feedback; turning your "concerns" into complaints; the economy working against you; and being blindsided because we think leaders operate logically. Being proactive puts more control in your hands and leaves less to chance. You can prevent being blindsided if you: develop your people skills; get comfortable and involved with e-business; stay abreast of health care trends; pick up the pace; and develop "You, Inc." There is a final component to prevailing over adverse circumstances--find your work-related passion and apply it to your career.

Scientific misconduct: three forms that directly harm others as the modus operandi of Mill's tyranny of the prevailing opinion.

PubMed

Cabbolet, Marcoen J T F

2014-03-01

Scientific misconduct is usually assumed to be self-serving. This paper, however, proposes to distinguish between two types of scientific misconduct: 'type one scientific misconduct' is self-serving and leads to falsely positive conclusions about one's own work, while 'type two scientific misconduct' is other-harming and leads to falsely negative conclusions about someone else's work. The focus is then on the latter type, and three known issues are identified as specific forms of such scientific misconduct: biased quality assessment, smear, and officially condoning scientific misconduct. These concern the improper ways how challenges of the prevailing opinion are thwarted in the modern world. The central issue is pseudoskepticism: uttering negative conclusions about someone else's work that are downright false. It is argued that this may be an emotional response, rather than a calculated strategic action. Recommendations for educative and punitive measures are given to prevent and to deal with these three forms of scientific misconduct.

Farmers prevailing perception profiles regarding GM crops: A classification proposal.

PubMed

Almeida, Carla; Massarani, Luisa

2018-04-01

Genetically modified organisms have been at the centre of a major public controversy, involving different interests and actors. While much attention has been devoted to consumer views on genetically modified food, there have been few attempts to understand the perceptions of genetically modified technology among farmers. By investigating perceptions of genetically modified organisms among Brazilian farmers, we intend to contribute towards filling this gap and thereby add the views of this stakeholder group to the genetically modified debate. A comparative analysis of our data and data from other studies indicate there is a complex variety of views on genetically modified organisms among farmers. Despite this diversity, we found variations in such views occur within limited parameters, concerned principally with expectations or concrete experiences regarding the advantages of genetically modified crops, perceptions of risks associated with them, and ethical questions they raise. We then propose a classification of prevailing profiles to represent the spectrum of perceptions of genetically modified organisms among farmers.

Some Behaviorial Science Measurement Concerns and Proposals.

PubMed

Nesselroade, John R; Molenaar, Peter C M

2016-01-01

Primarily from a measurement standpoint, we question some basic beliefs and procedures characterizing the scientific study of human behavior. The relations between observed and unobserved variables are key to an empirical approach to building explanatory theories and we are especially concerned about how the former are used as proxies for the latter. We believe that behavioral science can profitably reconsider the prevailing version of this arrangement because of its vulnerability to limiting idiosyncratic aspects of observed/unobserved variable relations. We describe a general measurement approach that takes into account idiosyncrasies that should be irrelevant to the measurement process but can intrude and may invalidate it in ways that distort and weaken relations among theoretically important variables. To clarify further our major concerns, we briefly describe one version of the measurement approach that fundamentally supports the individual as the primary unit of analysis orientation that we believe should be preeminent in the scientific study of human behavior.

In 1808, Dom João VI issued an edict which regulated the shipping and treatment of slaves on the transatlantic crossing from Africa. Two years later, Antonio de Saldanha da Gama, a member of the Treasury Council, drafted a letter discussing some points of the resolution. This key figure in the Portuguese administration of Brazil argued that his respectful considerations concerning the determinations of His Royal Highness were designed to improve them "for humanitarian and economic reasons." Safeguarded in the archives of Arquivo Histórico Ultramarino, this letter is transcribed, annotated, and contextualized here, supplying an interesting perspective on the prevailing concerns and justifications about the trafficking of African slaves to Brazil.

Are you sitting comfortably? Perspectives of the researchers and the researched on "being comfortable".

PubMed

Morris, Norma; Balmer, Brian

2006-01-01

In a study of volunteers in medical research, we found contrasting readings of "being comfortable" by the volunteer research subjects and the researchers. Although the experimental process (testing a new kind of diagnostic technology) involved some physical discomfort--and the researchers focused on this--the volunteers' concerns centred on feeling socially comfortable and managing feelings of embarrassment or isolation, and they generally made light of the physical aspects. The bias of volunteer concerns, which is understandable in terms of the different situations of researchers and volunteers and the different tensions they create, has potential implications for the engagement of researchers with their research subjects and prevailing standards for the ethical and accountable conduct of research.

Geographic distribution of dementia mortality: elevated mortality rates for black and white Americans by place of birth.

2011-01-01

We hypothesized that patterns of elevated stroke mortality among those born in the United States Stroke Belt (SB) states also prevailed for mortality related to all-cause dementia or Alzheimer Disease. Cause-specific mortality (contributing cause of death, including underlying cause cases) rates in 2000 for United States-born African Americans and whites aged 65 to 89 years were calculated by linking national mortality records with population data based on race, sex, age, and birth state or state of residence in 2000. Birth in a SB state (NC, SC, GA, TN, AR, MS, or AL) was cross-classified against SB residence at the 2000 Census. Compared with those who were not born in the SB, odds of all-cause dementia mortality were significantly elevated by 29% for African Americans and 19% for whites born in the SB. These patterns prevailed among individuals who no longer lived in the SB at death. Patterns were similar for Alzheimer Disease-related mortality. Some non-SB states were also associated with significant elevations in dementia-related mortality. Dementia mortality rates follow geographic patterns similar to stroke mortality, with elevated rates among those born in the SB. This suggests important roles for geographically patterned childhood exposures in establishing cognitive reserve.

Late Quaternary environmental dynamics in the Atacama Desert reconstructed from rodent midden pollen records

USGS Publications Warehouse

de Porras, M.E.; Maldonado, A.; De Pol-Holz, R.; Latorre, C.; Betancourt, Julio L.

2017-01-01

In the past two decades, much has been learned about the late Quaternary climate history of the Atacama Desert with some details still unclear about the seasonality, timing and extent of wet and dry phases. Modern climate studies reveal that, far from exhibiting a unique pattern, seasonal precipitation originates from many sources and mechanisms. For the last 16 ka, we attempt to sort out these complexities in pollen records from four fossil rodent midden series spanning 22°–25°S in northern Chile. Widespread wet conditions prevailed during the late Pleistocene and early Holocene, particularly between 13 and 9 ka, evidenced by <400 m lowering of pollen zones (plant communities) compared to today. Regional differences in the timing and magnitude of this displacement may be related to the prevailing source (tropical/extra‐tropical) or mode (NNW/SE) of tropical precipitation through time. Wet conditions persisted well into the early Holocene, lasting ∼1–1.5 ka longer than previously suggested. The pollen record suggests extreme drying ∼8 ka, possibly associated with a northward shift of the Inter Tropical Convergence Zone, tracking minimum insolation values at subtropical latitudes during the austral summer. The establishment of conditions similar to today happened ∼4 ka.

Advances in technology have led to the availability of smaller and more accurate sensors. Computer power to process large amounts of data is no longer the prevailing issue; thus multiple and redundant sensors can be used to obtain more accurate and comprehensive measurements in a space vehicle. The successful integration and commercialization of micro- and nanotechnology for aerospace applications require that a close and interactive relationship be developed between the technology provider and the end user early in the project. Close coordination between the developers and the end users is critical since qualification for flight is time-consuming and expensive. The successful integration of micro- and nanotechnology into space vehicles requires a coordinated effort throughout the design, development, installation, and integration processes

Clarifying conflict of interest.

PubMed

Brody, Howard

2011-01-01

As the debate over how to manage or discourage physicians' financial conflicts of interest with the drug and medical device industries has become more heated, critics have questioned or dismissed the concept of "conflict of interest" itself. A satisfactory definition relates conflict of interest to concerns about maintaining social trust and distinguishes between breaches of ethical duty and temptations to breach duty. Numerous objections to such a definition have been offered, none of which prevails on further analysis. Those concerned about conflicts of interest have contributed to misunderstandings, however, by failing to demonstrate when social arrangements leading to temptations to breach duties are in themselves morally blameworthy. Clarifying "conflict of interest" is important if we are eventually going to develop productive modes of engagement between medicine and for-profit industry that avoid the serious ethical pitfalls now in evidence.

Identity, prudential concern, and extended lives.

PubMed

Glannon, Walter

2002-06-01

Recent advances in human genetics suggest that it may become possible to genetically manipulate telomerase and embryonic stem cells to alter the mechanisms of aging and extend the human life span. But a life span significantly longer than the present norm would be undesirable because it would severely weaken the connections between past- and future-oriented mental states and turn the psychological grounds for personal identity and prudential concern for our future selves. In addition, the collective effects of longer lives might lower the quality of life for all people. These two problems provide reasons against genetic manipulation of cells to alter the length of the human life span.

Low-residue euthanasia of stranded mysticetes.

2014-01-01

Euthanasia of stranded large whales poses logistic, safety, pharmaceutical, delivery, public relations, and disposal challenges. Reasonable arguments may be made for allowing a stranded whale to expire naturally. However, slow cardiovascular collapse from gravitational effects outside of neutral buoyancy, often combined with severely debilitating conditions, motivate humane efforts to end the animal's suffering. The size of the animal and prevailing environmental conditions often pose safety concerns for stranding personnel, which take priority over other considerations. When considering chemical euthanasia, the size of the animal also necessitates large quantities of euthanasia agents. Drug residues are a concern for relay toxicity to scavengers, particularly for pentobarbital-containing euthanasia solutions. Pentobarbital is also an environmental concern because of its stability and long persistence in aquatic environments. We describe a euthanasia technique for stranded mysticetes using readily available, relatively inexpensive, preanesthetic and anesthetic drugs (midazolam, acepromazine, xylazine) followed by saturated KCl delivered via custom-made needles and a low-cost, basic, pressurized canister. This method provides effective euthanasia while moderating personnel exposure to hazardous situations and minimizing drug residues of concern for relay toxicity.

The Protean Toxicities of Lead: New Chapters in a Familiar Story

PubMed Central

Bellinger, David C.

2011-01-01

Many times in the history of lead toxicology the view that “the problem” has been solved and is no longer a major health concern has prevailed, only to have further research demonstrate the prematurity of this judgment. In the last decade, an extraordinary amount of new research on lead has illustrated, all too clearly, that “the problem” has not disappeared, and that, in fact, it has dimensions never before considered. Recent risk assessments have concluded that research has yet to identify a threshold level below which lead can be considered “safe.” Although children’s intelligence has traditionally been considered to be the most sensitive endpoint, and used as the basis for risk assessment and standard setting, increased lead exposure has been associated with a wide variety of other morbidities both in children and adults, in some cases at biomarker levels comparable to those associated with IQ deficits in children. In adults, these endpoints include all-cause mortality and dysfunctions in the renal, cardiovascular, reproductive, central nervous systems. In children, IQ deficits are observed at blood lead levels well below 10 μg/dL, and the dose-effect relationship appears to be supra-linear. Other health endpoints associated with greater early-life lead exposure in children include ADHD, conduct disorder, aggression and delinquency, impaired dental health, and delayed sexual maturation. Studies employing neuroimaging modalities such as volumetric, diffusion tensor, and functional MRI are providing insights into the neural bases of the cognitive impairments associated with greater lead exposure.

Two alternative models concerning the perialveolar microcirculation in mammalian lungs.

2005-01-01

Despite the fact that the concept of sheet-flow in the pulmonary microcirculation of mammals was introduced more than three decades ago, the capillary circulatory model still prevails in the physiological literature. Since cardiac output is identical in the systemic and in pulmonary circulations, it is noteworthy that in the former, the resulting arterial pressure is five times higher than that of the latter, which means that the corresponding microcirculations must be radically different. The present study addresses this problem from both morphological and physiological perspectives.

This article attempts to review the most current and the well-established facts concerning drug addiction and sexual dysfunction. Surprisingly, even though alcohol is prevalent in many societies with many myths surrounding its sexual-enhancing effects, current scientific research cannot provide a solid conclusion on its effect on sexual function. Unfortunately, the same concept applies to tobacco smoking; however, most of the current knowledge tends to support the notion that it, indeed, can negatively affect sexual function. Similar ambiguities also prevail with substances of abuse. Copyright © 2013 Elsevier Inc. All rights reserved.

The spectroscopic analysis of pristine cometary material provides a very important probe of the chemical identity of the material as well as of the physical and chemical conditions which prevailed during the comet's history. Concerning classical spectroscopy, the spectral regions which will most likely prove most useful are the infrared, the visible and ultraviolet. Newer spectroscopic techniques which have the potential to provide equally important information include nuclear magnetic resonance (NMR) and electron spin resonance (ESR). Each technique is summarized with emphasis placed on the kind of information which can be obtained.

On the theory of dynamics of dust grain in plasma

2013-03-01

The dynamics of rotationally symmetric dust grains in plasma embedded in a magnetic field are of concern. The general expressions for forces and torques acting on dust are found. It is shown that dust spinning is determined by torques related to both the Lorentz force (dominant for relatively small grains) and the gyro-motion of plasma particles impinging the grain (which prevails for large grains). The stability of grain spinning is analyzed and it is shown that, for some cases (e.g., oblate spheroid), there is no stable dynamic equilibrium of grain spinning.

Challenges and issues concerning mycotoxins contamination in oil seeds and their edible oils: Updates from last decade.

2017-01-15

Safety concerns pertaining towards fungal occurrence and mycotoxins contamination in agri-food commodities has been an issue of high apprehension. With the increase in evidence based research knowledge on health effects posed by ingestion of mycotoxins-contaminated food and feed by humans and livestock, concerns have been raised towards providing more insights on screening of agri-food commodities to benefit consumers. Available reports indicate majority of edible oil-yielding seeds to be contaminated by various fungi, capable of producing mycotoxins. These mycotoxins can enter human food chain via use of edible oils or via animals fed with contaminated oil cake residues. In this review, we have decisively evaluated available data (from the past decade) pertaining towards fungal occurrence and level of mycotoxins in various oil seeds and their edible oils. This review can be of practical use to justify the prevailing gaps, especially relevant to the research on presence of mycotoxins in edible plant based oils. Copyright © 2016 Elsevier Ltd.

Toxicity persistence to the nontarget amphipod Hyalella curvispina in runoff events following chlorpyrifos applications to soy experimental plots was compared in conventional and no-till management. Two application scenarios were compared: an early-season application with the soil almost bare and a late-season application after the foliage had attained complete soil cover. H. curvispina was exposed to chlorpyrifos using two different test systems: a short-term (48 h) runoff water exposure and a long-term (10 days) soil exposure. Both commonly used crop management practices for soybean production resulted in runoff toxicity following pesticide applications and represent a toxicity risk for adjacent inland waters. Toxicity persistence was longer after the earlier than the late season application, likely because of higher volatilization and photodecomposition losses from the soy canopy than from the soil. For the early-season application, toxicity persisted longer in the no-till plots than in the conventional tillage plots. Suspended matter was higher in the conventional treatment. Chlorpyrifos sorption to suspended matter likely contributed to the shorter persistence. For the late-season application, toxicity persisted longer in the conventional treatment. The causes remain conjectural. The soil organic carbon content was higher in the no-till treatment. Sorption to organic matter might have contributed to the shorter chlorpyrifos toxicity persistence in no-till management. Late applications are more frequent and prevail longer throughout the soy growing season. Overall, the no-till management practice seems preferably because shorter toxicity persistence in runoff represents a lower environmental risk for the adjacent inland waters.

Leukocyte Telomere Length in Newborns: Implications for the Role of Telomeres in Human Disease

PubMed Central

Factor-Litvak, Pam; Susser, Ezra; Kezios, Katrina; McKeague, Ian; Kark, Jeremy D.; Hoffman, Matthew; Kimura, Masayuki; Wapner, Ronald

2016-01-01

BACKGROUND AND OBJECTIVE: In adults, leukocyte telomere length (LTL) is variable, familial, and longer in women and in offspring conceived by older fathers. Although short LTL is associated with atherosclerotic cardiovascular disease, long LTL is associated with major cancers. The prevailing notion is that LTL is a “telomeric clock,” whose movement (expressed in LTL attrition) reflects the pace of aging. Accordingly, individuals with short LTL are considered to be biologically older than their peers. Recent studies suggest that LTL is largely determined before adulthood. We examined whether factors that largely characterize LTL in adults also influence LTL in newborns. METHODS: LTL was measured in blood samples from 490 newborns and their parents. RESULTS: LTL (mean ± SD) was longer (9.50 ± 0.70 kb) in newborns than in their mothers (7.92 ± 0.67 kb) and fathers (7.70 ± 0.71 kb) (both P < .0001); there was no difference in the variance of LTL among the 3 groups. Newborn LTL correlated more strongly with age-adjusted LTL in mothers (r = 0.47; P < .01) than in fathers (r = 0.36; P < .01) (P for interaction = .02). Newborn LTL was longer by 0.144 kb in girls than in boys (P = .02), and LTL was longer by 0.175 kb in mothers than in fathers (P < .0001). For each 1-year increase in father’s age, newborn LTL increased by 0.016 kb (95% confidence interval: 0.04 to 0.28) (P = .0086). CONCLUSIONS: The large LTL variation across newborns challenges the telomeric clock model. Having inherently short or long LTL may be largely determined at birth, anteceding by decades disease manifestation in adults. PMID:26969272

Child health interventions in urban slums: are we neglecting the importance of nutrition?

PubMed

Wray, J D

1986-12-01

During the early part of the twentieth century, there were dramatic falls in the mortality rates in many cities in the West. The reasons for this improvement are of considerable relevance today because the conditions which prevailed at that time in cities such as New York are comparable to those prevailing in many slums of the Third World today. Some early studies linked the improvements in health, as measured by mortality rates, to a better level of nutrition. The importance of nutrition is now widely accepted and there are many studies which show the association between nutrient intake and both mortality and morbidity, and in particular between breast feeding and infant mortality rates. It is sometimes assumed that, because nutrition indicators for city populations have improved, there is no longer a major problem of malnutrition in urban areas. However, it is likely that the figures hide disparities through aggregation, and studies in slums rather than cities as a whole give a much less encouraging picture. Poverty is at the root of many of the nutritional and associated health problems, but the children who will be born over the coming decades cannot afford to wait for a new economic order to provide the solution. Through the promotion of breast feeding, education, growth monitoring and food supplementation, necessary help can be targeted at this vulnerable population.

Determinants of breast-feeding patterns in an urban society of India.

Nath, D C; Goswami, G

1997-08-01

Breast feeding is the focus of rapidly growing interest in many areas of demographic research. However, relatively few rigorous studies on breast-feeding patterns and correlates in contemporary India have been published. This study uses data from a retrospective survey conducted in 1991-1992 to investigate current breast-feeding patterns and to identify the key factors that influence the duration of exclusive breast feeding and infant's age at the time of weaning in an urban Hindu society of the northeast Indian state of Assam. Applying life table procedures and a hazards regression model, we found evidence that the median duration of exclusive breast feeding and infant's age at the time of weaning were negatively associated with mother's education, per capita income, and social status of the household. Those infants who were breast-fed longer at night than in the daytime were also at greater risk of earlier introduction of non-breast-milk foods and of earlier termination of breast feeding than infants who were breast-fed longer during the day. Gender bias toward males in rearing infants prevails in this urban society, and male infants were found to have a significantly lower risk of early weaning than female infants.

Understanding men's health and illness: a gender-relations approach to policy, research, and practice.

PubMed

Schofield, T; Connell, R W; Walker, L; Wood, J F; Butland, D L

2000-05-01

Men's health has emerged as an important public concern that may require new kinds of healthcare interventions and increased resources. Considerable uncertainty and confusion surround prevailing understandings of men's health, particularly those generated by media debate and public policy, and health research has often operated on oversimplified assumptions about men and masculinity. A more useful way of understanding men's health is to adopt a gender-relations approach. This means examining health concerns in the context of men's and women's interactions with each other, and their positions in the larger, multidimensional structure of gender relations. Such an approach raises the issue of differences among men, which is a key issue in recent research on masculinity and an important health issue. The gender-relations approach offers new ways of addressing practical issues of healthcare for men in college environments.

Ising universality describes emergent long-range synchronization of coupled ecological oscillators

NASA Astrophysics Data System (ADS)

Noble, Andrew

Understanding the synchronization of oscillations across space is fundamentally important to many scientific disciplines. In ecology, long-range synchronization of oscillations in spatial populations may elevate extinction risk and signal an impending catastrophe. The prevailing assumption is that synchronization on distances longer than the dispersal scale can only be due to environmental correlation. By contrast, recent work shows how scale-invariant synchronization can emerge from locally coupled population dynamics. In particular, we have found that the transition from incoherence to long-range synchronization of coupled ecological two-cycles is described by the Ising universality class. I will discuss evidence that an Ising critical point describes long-range correlations found in data on the individual yields of female pistachio trees in a large orchard.

Seasonal prevailing surface winds are analyzed in the territory of Northern Serbia, using observational data from 12 meteorological stations over several decades. In accordance with the general definition of prevailing wind, two special definitions of this term are used. The seasonal wind roses in 16 directions at each station are analyzed. This study shows that the prevailing winds in Northern Serbia have northwestern and southeastern directions. Circulation weather types over Serbia are presented in order to determine the connections between the synoptic circulations and prevailing surface winds. Three controlling pressure centers, i.e., the Mediterranean cyclone, Siberian high, and the Azores anticyclone, appear as the most important large-scale factors that influence the creation of the prevailing winds over Northern Serbia. Beside the synoptic cause of the prevailing winds, it is noted that the orography of the eastern Balkans has a major influence on the winds from the second quadrant. It was found that the frequencies of circulation weather types are in agreement with those of the prevailing winds over Northern Serbia.

Management of a hyperactive teen and cardiac safety.

PubMed

Sowinski, Heather; Karpawich, Peter P

2014-02-01

Since the earliest descriptions of the condition, controversy has prevailed as to the existence of as well as appropriate management of attention deficit hyperactivity disorder. Often diagnosed in childhood, symptoms of attention deficit hyperactivity disorder can continue into adolescence and adulthood, requiring lifelong therapy. Effective therapeutic interventions include stimulant medications with all their respective potential side effects, including the cardiovascular system. However, although initial studies raised concerns for an increase in serious adverse cardiovascular effects among children receiving these drugs, more recent and extensive reports have failed to substantiate those findings among young patients.

Diniz, Debora

2005-01-01

The Case Against Non-Compliance with the Fundamental Principle concerning Anencephaly, under review by the Brazilian Supreme Court, is a milestone in the debate on abortion in Latin America. Since the currently prevailing version of the Brazilian Penal Code was enacted in 1940, there has been fierce resistance to any change in the country's abortion policy. This article discusses the arguments and political strategies used in the anencephaly suit brought before the Supreme Court, particularly the ethical and legal position that interruption of pregnancy in cases of anencephaly does not constitute abortion, but should be considered a therapeutic anticipation of delivery.

Lignin biopolymer based triboelectric nanogenerators

NASA Astrophysics Data System (ADS)

Bao, Yukai; Wang, Ruoxing; Lu, Yunmei; Wu, Wenzhuo

2017-07-01

Ongoing research in triboelectric nanogenerators (TENGs) focuses on increasing power generation, but obstacles concerning economical and eco-friendly utilization of TENGs continue to prevail. Being the second most abundant biopolymer on earth, lignin offers a valuable opportunity for low-cost TENG applications in biomedical devices, benefitting from its biodegradability and biocompatibility. Here, we develop for the first time a lignin biopolymer based TENGs for harvesting mechanical energy in the environment, which shows great potential for self-powered biomedical devices among other applications and opens doors to new technologies that utilize otherwise wasted materials for economically feasible and ecologically friendly production of energy devices.

Submerged Gas Jet Penetration: A Study of Bubbling Versus Jetting and Side Versus Bottom Blowing in Copper Bath Smelting

NASA Astrophysics Data System (ADS)

Kapusta, Joël P. T.

2017-06-01

Although the bottom blowing ShuiKouShan process has now been widely implemented in China, in both lead and copper smelters, some doubts, questions, and concerns still seem to prevail in the metallurgical community outside China. In the author's opinion, part of these doubts and concerns could be addressed by a better general understanding of key concepts of submerged gas injection, including gas jet trajectory and penetration, and the concept, application, and benefits of sonic injection in jetting regime. To provide some answers, this article first offers a discussion on the historical developments of the theory and mathematical characterization of submerged gas jet trajectory, including the proposed criteria for the transition from bubbling to jetting regime and the application of the Prandtl-Meyer theory to submerged gas jets. A second part is devoted to a quantitative study of submerged gas jet penetration in copper bath smelting, including a comparison between bubbling and jetting regimes, and side versus bottom blowing. In the specific cases studied, the calculated gas jet axis trajectory length in jetting regime is 159 cm for bottom blowing, whereas it varies between 129 and 168 cm for side blowing for inclination angles of +18° to -30° to the horizontal. This means that side blowing in the jetting regime would provide a deeper penetration and longer gas jet trajectory than generally obtained by conventional bath smelting vessels such as the Noranda and Teniente reactors. The theoretical results of this study do corroborate the successful high-intensity practice of the slag make converting process at Glencore Nickel in Canada that operates under high oxygen shrouded injection in the jetting regime, and this would then suggest that retrofitting conventional low-pressure, side-blowing tuyeres of bath smelting and converting reactors with sonic injectors in jetting regime certainly appears as a valuable option for process intensification with higher oxygen enrichment, without major process changes or large capital expenditure, i.e., no need for full reactor replacement.

Melatonin for insomnia in children with autism spectrum disorders.

PubMed

Andersen, Ivy M; Kaczmarska, JoAnna; McGrew, Susan G; Malow, Beth A

2008-05-01

We describe our experience in using melatonin to treat insomnia, a common sleep concern, in children with autism spectrum disorders. One hundred seven children (2-18 years of age) with a confirmed diagnosis of autism spectrum disorders who received melatonin were identified by reviewing the electronic medical records of a single pediatrician. All parents were counseled on sleep hygiene techniques. Clinical response to melatonin, based on parental report, was categorized as (1) sleep no longer a concern, (2) improved sleep but continued parental concerns, (3) sleep continues to be a major concern, and (4) worsened sleep. The melatonin dose varied from 0.75 to 6 mg. After initiation of melatonin, parents of 27 children (25%) no longer reported sleep concerns at follow-up visits. Parents of 64 children (60%) reported improved sleep, although continued to have concerns regarding sleep. Parents of 14 children (13%) continued to report sleep problems as a major concern, with only 1 child having worse sleep after starting melatonin (1%), and 1 child having undetermined response (1%). Only 3 children had mild side-effects after starting melatonin, which included morning sleepiness and increased enuresis. There was no reported increase in seizures after starting melatonin in children with pre-existing epilepsy and no new-onset seizures. The majority of children were taking psychotropic medications. Melatonin appears to be a safe and well-tolerated treatment for insomnia in children with autism spectrum disorders. Controlled trials to determine efficacy appear warranted.

Wind ripples in low density atmospheres

NASA Technical Reports Server (NTRS)

Miller, J. S.; Marshall, J. R.; Greeley, R.

1987-01-01

The effect of varying fluid density (rho) on particle transport was examined by conducting tests at atmospheric pressures between 1 and 0.004 bar in the Martian Surface Wind Tunnel (MARSWIT). This study specifically concerns the effect of varying rho on the character of wind ripples, and elicits information concerning generalized ripple models as well as specific geological circumstances for ripple formation such as those prevailing on Mars. Tests were conducted primarily with 95 micron quartz sand, and for each atmospheric pressure chosen, tests were conducted at two freestream wind speeds: 1.1 U*(t) and 1.5 U*(t), where U*(t) is saltation threshold. Preliminary analysis of the data suggests: (1) ballistic ripple wavelength is not at variance with model predictions; (2) an atmospheric pressure of approximately 0.2 bar could represent a discontinuity in ripple behavior; and (4) ripple formation on Mars may not be readily predicted by extrapolation of terrestrial observations.

Christianity and epilepsy.

PubMed

Owczarek, K; Jędrzejczak, J

2013-01-01

Epileptic seizures have been known from time immemorial. Throughout the ages, however, ideas concerning the aetiology and treatment of epilepsy have changed considerably. Epilepsy is mentioned many times in the Pentateuch, where it is portrayed as a mysterious condition, whose symptoms, course and contingencies evade rational laws and explanations. In the Middle Ages, the accepted view which prevailed in social consciousness was that patients with epilepsy were possessed by Satan and other impure spirits. One common method of treatment of epileptic seizures was to submit the patient to cruel exorcisms. Patients were frequently injured in the process and some of them even died. Our understanding of epilepsy and its social consequences has improved considerably within the last century. The most significant progress as far as diagnosis and treatment of epilepsy is concerned took place in the last four decades of the twentieth century. Although we now know much more about epilepsy than we used to, this knowledge is still insufficiently popularized.

Safety climate in dialysis centers in Saudi Arabia: a multicenter study.

The aim of this study was to assess the safety climate as perceived by nurses and physicians in the dialysis units in Saudi Arabia. This is a cross-sectional survey-based multicenter study using the Safety Climate Scale, which assesses the perception by staff of the prevailing climate of safety. We used 17 items in this survey. These could be further divided into 3 summative categories: (a) handling of errors and safety concerns (9 items), (b) leadership emphasis of safety (7 items), and (c) overall safety recommendation (1 item). The survey uses 5 Likert scale options (1, disagree strongly; 2, disagree slightly; 3, neutral; 4, agree slightly; and 5, agree strongly). There were 509 respondents--a response rate of 76.6% and 53.3% among nurses and physicians, respectively. The internal consistency using Cronbach α was 0.899. The overall mean (SD) of satisfaction with safety climate was higher among the nurses than the physicians (4.13 [1.1] and 4.05 [1.7], respectively; P = 0.029). The overall agreement rate was 73.8%, with more nurses than physicians agreeing that safety climate prevails the dialysis center (75.4% versus 72.1%, respectively; P = 0.047).The respondents perceived a stronger commitment to safety from their clinical area leaders than from senior leaders in the organization (76.2% and 72.4%, respectively). In addition, the physicians gave lower scores to more questions than the nurses particularly in 3 areas, namely, "leadership is driving us to be a safety-centered institution" (71.5% versus 76.5%; P = 0.037), "I am encouraged by my colleagues to report any patient safety concerns I may have" (67.4% versus 84.7%; P = 0.03), and "I know proper channels to ask questions about safety" (69.6% versus 87.2%; P = 0.002).The scores by the physicians in all the 3 summative categories were again less than the scores by the nurses, but this did not reach a statistical significance. The nurses had higher perceptions of a prevailing safety climate than the physicians. There was a perception of a stronger commitment to safety from their clinical area leaders than from senior leaders in the organization. Senior management needs to relay their commitments to safety more effectively especially to physicians and to open clear and easily accessible channels for communication for safety issues.

The meteorologic phenomenon of drought in the Southwest: Chapter A in Drought in the Southwest, 1942-56

USGS Publications Warehouse

Thomas, H.E.

1962-01-01

The recent drought is one of several which have been recorded in the arid Southwest in the past century. In regions where precipitation comes chiefly from a single source, as in California and the Great Plains, prevailingly dry periods have alternated with wetter periods, each lasting 10 to 15 years. In the intervening area that includes the basins of the Colorado River and Rio Grande and numerous basins of interior drainage, a deficiency from one source may be ameliorated in some localities by precipitation from another source; in other areas all sources have failed and the drought has continued for a quarter of a century. Earlier droughts of similar duration, and some of longer period, are indicated by historic records and by studies of tree rings, lake levels, and archeologic data.

The Obligation to Participate in Biomedical Research

PubMed Central

Schaefer, G. Owen; Emanuel, Ezekiel J.; Wertheimer, Alan

2009-01-01

The prevailing view is that participation in biomedical research is above and beyond the call of duty. While some commentators have offered reasons against this, we propose a novel public goods argument for an obligation to participate in biomedical research. Biomedical knowledge is a public good, available to any individual even if that individual does not contribute to it. Participation in research is a critical way to support that important public good. Consequently, we all have a duty to participate. The current social norm is that people participate only if they have a good reason to do so. The public goods argument implies that people should participate unless they have a good reason not to. Such a shift would be of great aid to the progress of biomedical research, eventually making our society significantly healthier and longer-lived. PMID:19567441

Migration, settlement change and health in post-apartheid South Africa: Triangulating health and demographic surveillance with national census data1

PubMed Central

COLLINSON, MARK A.; TOLLMAN, STEPHEN M.; KAHN, KATHLEEN

2010-01-01

Background World population growth will be increasingly concentrated in the urban areas of the developing world; however, some scholars caution against the oversimplification of African urbanization noting that there may be “counter-urbanization” and a prevailing pattern of circular rural–urban migration. The aim of the paper is to examine the ongoing urban transition in South Africa in the post-apartheid period, and to consider the health and social policy implications of prevailing migration patterns. Methods Two data sets were analysed, namely the South African national census of 2001 and the Agincourt health and demographic surveillance system. A settlement-type transition matrix was constructed on the national data to show how patterns of settlement have changed in a five-year period. Using the sub-district data, permanent and temporary migration was characterized, providing migration rates by age and sex, and showing the distribution of origins and destinations. Findings The comparison of national and sub-district data highlight the following features: urban population growth, particularly in metropolitan areas, resulting from permanent and temporary migration; prevailing patterns of temporary, circular migration, and a changing gender balance in this form of migration; stepwise urbanization; and return migration from urban to rural areas. Conclusions Policy concerns include: rural poverty exacerbated by labour migration; explosive conditions for the transmission of HIV; labour migrants returning to die in rural areas; and the challenges for health information created by chronically ill migrants returning to rural areas to convalesce. Lastly, suggestions are made on how to address the dearth of relevant population information for policy-making in the fields of migration, settlement change and health. PMID:17676507

Removal of Mycobacterium avium subspecies hominissuis (MAH) from drinking water by coagulation, flocculation and sedimentation processes.

PubMed

Wong, E A; Shin, G-A

2015-03-01

There has been a growing concern over human exposure to Mycobacterium avium subspecies hominissuis (MAH) through drinking water due to its ubiquitous presence in natural waters and remarkable resistance to both chemical and physical disinfectants in drinking water treatment processes. However, little is known about the effectiveness of physico-chemical water treatment processes to remove MAH. Therefore, we determined the removal of MAH by alum coagulation, flocculation and sedimentation processes in optimized drinking water treatment conditions using standard jar test equipment. Contrary to the prevailing hypothesis, the results of this study show that removal of MAH by coagulation, flocculation and sedimentation processes was only moderate (approx. 0.65 log10) under low turbidity treatment conditions and the removal of MAH was actually lower than that of Escherichia coli (reference bacterium) in all the waters tested. Overall, the results of this study suggested that coagulation, flocculation and sedimentation processes may not be a reliable treatment option for removing MAH, and more efforts to find an effective control measures against MAH should be made to reduce the risk of MAH infection from drinking water.

As these processes have been the last remaining conventional drinking water treatment processes that might be effective against MAH, more efforts should be urgently made to find an effective control measures against this important waterborne pathogen. © 2014 The Society for Applied Microbiology.

Patterns of trunk spine growth in two congeneric species of acanthocephalan: investment in attachment may differ between sexes and species.

PubMed

Hernández-Orts, Jesús S; Timi, Juan T; Raga, Juan A; García-Varela, M; Crespo, Enrique A; Aznar, Francisco J

2012-06-01

Acanthocephalans have evolved a hooked proboscis and some taxa have trunk spines to attach to their definitive hosts. These structures are generated before being used, thus a key question is how investment in attachment could optimally be allocated through the ontogeny. The number and arrangement of hooks and spines are never modified in the definitive host, but it is unclear whether these structures grow during adult development. A comparison of the size of trunk spines between cystacanths and adults of Corynosoma cetaceum and C. australe indicated that spines grow in both species, but only in females, which also had significantly larger spines than males. This sexual dimorphism did not result from pure allometry because the body of females was smaller, and did not grow more than that of males. However, having a longer lifespan, females would need to withstand the extreme flow conditions prevailing in marine mammals for longer, inducing different investment and development schedules for spines. Patterns of spine growth also differed between species: fore-trunk spines grew in both species, but hind-trunk spines did only in C. cetaceum. In conclusion, investment strategies on attachment may differ, not only between congeneric species of acanthocephalan, but also between sexes of the same species.

2015-01-01

Governmental officials, health and safety professionals, early responders, and the public are interested in the perceptions and concerns of people faced with a crisis, especially during and immediately after a disaster strikes. Reliable information can lead to increased individual and community preparedness for upcoming crises. The objective of this research was to evaluate concerns of coastal and central New Jersey residents within the first 100 days of Superstorm Sandy’s landfall. Respondents living in central New Jersey and Jersey shore communities were differentially impacted by the storm, with shore residents having higher evacuation rates (47% vs. 13%), more flood waters in their homes, longer power outages (average 23 vs. 6 days), and longer periods without Internet (29 vs. 6 days). Ratings of concerns varied both among and within categories as a function of location (central vs. coastal New Jersey), stressor level (ranging from 1 to 3 for combinations of power outages, high winds, and flooding), and demographics. Respondents were most concerned about property damage, health, inconveniences, ecological services, and nuclear power plants in that order. Respondents from the shore gave higher ratings to the concerns within each major category, compared to those from central Jersey. Four findings have implications for understanding future risk, recovery, and resiliency: (1) respondents with the highest stressor level (level 3) were more concerned about water damage than others, (2) respondents with flood damage were more concerned about water drainage and mold than others, (3) respondents with the highest stressor levels rated all ecological services higher than others, and (4) shore respondents rated all ecological services higher than central Jersey residents. These data provide information to design future preparedness plans, improve resiliency for future severe weather events, and reduce public health risk. PMID:27011757

Matrix management in hospitals: testing theories of matrix structure and development.

PubMed

Burns, L R

1989-09-01

A study of 315 hospitals with matrix management programs was used to test several hypotheses concerning matrix management advanced by earlier theorists. The study verifies that matrix management involves several distinctive elements that can be scaled to form increasingly complex types of lateral coordinative devices. The scalability of these elements is evident only cross-sectionally. The results show that matrix complexity is not an outcome of program age, nor does matrix complexity at the time of implementation appear to influence program survival. Matrix complexity, finally, is not determined by the organization's task diversity and uncertainty. The results suggest several modifications in prevailing theories of matrix organization.

Electromagnetic eigenmodes of collisional and collisionless plasmas and their stability to stimulated Brillouin scattering

NASA Astrophysics Data System (ADS)

Pathak, Vishwa Bandhu; Tripathi, V. K.

2007-02-01

Nonlinear electromagnetic eigenmodes of collisional and collisionless plasmas, when the temporal extent of the modes is longer than the ambipolar diffusion time, have been investigated. The nonlinearity in a collisionless plasma arises through ponderomotive force, whereas in collisional plasmas Ohmic nonlinearity prevails. The mode structure in both cases, representing a balance between the nonlinearity-induced self-convergence and diffraction-induced divergence, closely resembles Gaussian form. The spot size of the mode decreases with the increasing axial amplitude of the laser, attains a minimum, and then rises very gradually. The modes are susceptible to stimulated Brillouin backscattering. The growth rate of the Brillouin process initially increases with mode amplitude, attains a maximum, and then decreases. The reduction in the growth rate is caused by strong electron evacuation from the axial region by the ponderomotive force and thermal pressure gradient force created by nonuniform Ohmic heating.

Distributed Egg Production Functions for Meloidogyne arenaria in Grape Varieties and Consideration of the Mechanistic Relationship between Plant and Parasite.

PubMed

Ferris, H; Schneider, S M; Semenoff, M C

1984-04-01

Nematode egg production rates, as mediated by environmental conditions and host status, are important determinants of population development. Rates of egg production by Meloidogyne arenaria varied from 0.48 to 1.0 egg per female per DD (degree days above 10 C) in different grape varieties. The length of the egg production period ranged from 550 to 855 DD where measurable, and was generally longer in those varieties where the production rate was slow. We hypothesize that if a successful infection site is established, a constant number of eggs is produced if favorable environmental conditions prevail. Mechanistic coupling structures between plant growth and nematode population models are formulated. The nematode population influences metabolite supply through its effect on physiological efficiency and also acts as a metabolic sink; the degree of plant physiological stress influences nematode population development by affecting the sex ratio and egg production rates.

Collisional and radiative processes in high-pressure discharge plasmas

Becker, Kurt H.; Kurunczi, Peter F.; Schoenbach, Karl H.

2002-05-01

Discharge plasmas at high pressures (up to and exceeding atmospheric pressure), where single collision conditions no longer prevail, provide a fertile environment for the experimental study of collisions and radiative processes dominated by (i) step-wise processes, i.e., the excitation of an already excited atomic/molecular state and by (ii) three-body collisions leading, for instance, to the formation of excimers. The dominance of collisional and radiative processes beyond binary collisions involving ground-state atoms and molecules in such environments allows for many interesting applications of high-pressure plasmas such as high power lasers, opening switches, novel plasma processing applications and sputtering, absorbers and reflectors for electromagnetic waves, remediation of pollutants and waste streams, and excimer lamps and other noncoherent vacuum-ultraviolet light sources. Here recent progress is summarized in the use of hollow cathode discharge devices with hole dimensions in the range 0.1-0.5 mm for the generation of vacuum-ultraviolet light.

Internet Pornography Use, Body Ideals, and Sexual Self-Esteem in Norwegian Gay and Bisexual Men.

PubMed

Kvalem, Ingela Lundin; Træen, Bente; Iantaffi, Alex

2016-01-01

The purpose of this study was to explore the relationship between perception of own appearance, Internet pornography consumption, preferences for pornographic actors' appearance, and sexual self-esteem in gay and bisexual men in Norway. An online survey of 477 gay and bisexual men showed that, despite the prevailing muscular and lean gay body ideal, many men with less ideal bodies also preferred to watch pornographic actors with body types similar to their own. Self-perceived attractiveness, having an ideal body type, and viewing Internet pornography in longer sessions each made a unique contribution to higher self-esteem as a sexual partner. Preferring to watch pornographic actors with ideal bodies was not related to sexual self-esteem. The findings underscore the importance for gay or bisexual men of both self-perceived attractiveness and being athletic or young and fit, for a positive self-evaluation of sexual performance and competence.

Population dynamics of transgenic strain Escherichia coli Z905/pPHL7 in freshwater and saline lake water microcosms with differing microbial community structures

Popova, L. Yu.; Kargatova, T. V.; Ganusova, E. E.; Lobova, T. I.; Boyandin, A. N.; Mogilnaya, O. A.; Pechurkin, N. S.

Populations of Escherichia coli Z905/pPHL7, a transgenic microorganism, were heterogenic in the expression of plasmid genes when adapting to the conditions of water microcosms of various mineralization levels and structure of microbial community. This TM has formed two subpopulations (ampicillin-resistant and ampicillin-sensitive) in every microcosm. Irrespective of mineralization level of a microcosm, when E. coli Z905/pPHL7 alone was introduced, the ampicillin-resistant subpopulation prevailed, while introduction of the TM together with indigenous bacteria led to the dominance of the ampicillin-sensitive subpopulation. A high level of lux gene expression maintained longer in the freshwater microcosms than in sterile saline lake water microcosms. A horizontal gene transfer has been revealed between the jointly introduced TM and Micrococcus sp. 9/pSH1 in microcosms with the Lake Shira sterile water.

[Women's complaint leadership in the Causa Kleinwächter. A contribution to patient history of the Innsbruck maternity hospital].

PubMed

Hilber, Marina

On the basis of the Innsbruck Maternity Clinic this paper deals with the individual and collective worlds of experience of obstetric patients. However, not only the patient's view on the proceedings in this specific medical space is being reconstructed, also the prevailing conventions surrounding the treatment of pregnant, parturient and puerperal patients serving as clinical material in obstetric research and education are critically scrutinised. At the centre of this paper stands Dr. Ludwig Kleinwächter's period of duty, who acted as professor for obstetrics and gynaecology in Innsbruck between 1877 and 1881. During this period numerous conflicts regarding the treatment of patients are documented. Concerned about the good reputation of the Maternity Clinic, the Tyrolean State Committee, as the Clinic's provider, tried to solve the crisis. The existing letters of complaint and protocols do not only give a voice to the women concerned, but also to the medical professions as well as the local political representatives involved.

Preliminary acclimation strategies for successful startup in conventional biofilters.

PubMed

Elías, Ana; Barona, Astrid; Gallastegi, Gorka; Rojo, Naiara; Gurtubay, Luis; Ibarra-Berastegi, Gabriel

2010-08-01

The question of how to obtain the best inocula for conventional biofilters arises when an acclimation/adaptation procedure is to be applied. Bearing in mind that no standardized procedure for acclimating inocula exists, certain preliminary strategies for obtaining an active inoculum from wastewater treatment sludge are proposed in this work. Toluene was the contaminant to be degraded. Concerning the prior separation of sludge phases, no obvious advantage was found in separating the supernatant phase of the sludge before acclimation. As far as a continuous or discontinuous acclimation mode is concerned, the latter is recommended for rapidly obtaining acclimated sludge samples by operating the system for no longer than 1 month. The continuous mode rendered similar degradation rates, although it required longer operating time. Nevertheless, the great advantage of the continuous system lay in the absence of daily maintenance and the ready availability of the activated sample.

Water Velocities and the Potential for the Movement of Bed Sediments in Sinclair Inlet of Puget Sound, Washington

Gartner, Jeffrey W.; Prych, E.A.; Tate, G.B.; Cacchione, D.A.; Cheng, R.T.; Bidlake, W.R.; Ferreira, J.T.

Sinclair Inlet is a small embayment of Puget Sound in the State of Washington. The inlet, about 6.5 kilometers long and 1.5 kilometers wide, is the site of Puget Sound Naval Shipyard. There are concerns that bed sediments in the inlet may have been contaminated as a result of activities at the shipyard, and that these sediments could be resuspended by tide- and wind-driven currents and transported within the inlet or out of the inlet to other parts of Puget Sound. This study was conducted to provide information concerning the potential for sediment resuspension in the inlet. To obtain the necessary data, vertical profiles of water current from about 2 meters above the bed to 2 meters below the water surface were monitored with acoustic Doppler current profilers (ADCPs) at three locations during a 6.5-week winter period and a 4.5-week summer period in 1994. In addition, during the winter period, water velocites between 0.19 and 1.20 meters above the bed were measured with current meters using an instrument package called Geoprobe, which was deployed near one of the ADCPs. Other instruments on the Geoprobe measured light transmissivity, and a camera periodically took photographs of the bottom. Instruments on the Geoprobe and on the ADCPs also measured conductivity (for determining salinity), temperature, and pressure (for determinining tide). Samples of bed sediment and water samples for determining suspended-sediment concentration were collected at each of the current-measurement stations. Wind speed and direction were measured at three stations during a 12-month period, and tide was measured at one of these stations. Water currents measured at the three locations in Sinclair Inlet were relatively weak. Typical speeds were 5 to 10 centimeters per second, and the RMS (root-mean-square) speeds were less than 8 centimeters per second. Tidal and residual currents were of similar magnitude. Residual currents near the bottom typically were flowing in the opposite direction of the prevailing wind, while surface currents were in the same direction as the prevailing wind. During most of the year, the prevailing wind was from the soutwest quadrant; however, during July and August, the prevailing wind was usually from the northeast quadrant. The RMS of the total shear velocity for each ADCP station and measurement period, which was estimated from observed profiles of current velocity, ranged from 0.31 centimeters per second to 0.44 centimeters per second. The skin-friction component of the shear velocity was estimated to be no more than half the total. Critical shear velocity, estimated from particle sizes and density of the bed material, was 0.39 centimeters per second or larger. Comparisons of the skin-friction components of total bottom shear velocities with estimates of the critical shear velocity necessary for resuspension of the bed sediments indicate that resuspension occurs only infrequently, usually at times of maximum current during the tidal cycle. This conclusion is supported by measurements near the bed of light transmissivity, which is related to suspended-sediment concentration.

Between exclusion and emancipation: Foucault's ethics and disability.

PubMed

Pezdek, Krzysztof; Rasiński, Lotar

2017-04-01

The aim of the study was to demonstrate how Foucault's ethics, which we understand as a tension between exclusion and emancipation, helps both critically reassess two disability models that prevail in the contemporary literature concerning disability, that is the medical model and the social one, and support and inspire an ethical project of including people with disabilities in spheres of life from which they have been excluded by various power/knowledge regimes. We claim, following Foucault, that such a project should be informed by critical reflection on exclusion-generating forms of knowledge about people with disabilities and focused on individual ethical actions fostering self-realization and emancipation of people with disability. © 2016 John Wiley & Sons Ltd.

In France, since the approval of the first bioethics laws in 1994, the principle of the anonymity of sperm donors has prevailed. This choice is regularly challenged, namely by children who have been conceived under these conditions and have now reached adulthood. In this paper, we will briefly describe the reasons that led practitioners of assisted reproduction to endorse the anonymity principle in 1994. Secondly, we will elaborate on the reasons why this principle is becoming so controversial today. Finally, we shall examine two possible outcomes of the debate, highlighting their respective legitimacy as well as their consequences, as far as the rights of children, the notion of the family, and medical practice are concerned.

A parabolic variational inequality arising from the valuation of strike reset options

NASA Astrophysics Data System (ADS)

Yang, Zhou; Yi, Fahuai; Dai, Min

A strike reset option is an option that allows its holder to reset the strike price to the prevailing underlying asset price at a moment chosen by the holder. The pricing model of the option can be formulated as a one-dimensional parabolic variational inequality, or equivalently, a free boundary problem, where the free boundary just corresponds to the optimal reset strategy adopted by the holder of the option. This paper is concerned with the theoretical analysis of the model. The existence and uniqueness of the solution are established. Furthermore, we study properties of the free boundary. The monotonicity and C smoothness of the free boundary are proven in some situations.

The myth of hypnosis: the need for remythification.

PubMed

Meyerson, Joseph

2014-01-01

Myths or misconceptions concerning hypnosis are regarded among the major barriers to effective implementation of hypnosis. Contemporary hypnotherapists are expected to elicit patients' misconceptions and to provide explanations that distinguish between mystical and scientific perceptions of hypnosis and that offer a picture of the state of the art of hypnosis. Dealing with misconceptions on a rational and cognitive level seems to have the ability to change a patient's conscious knowledge and understanding of hypnosis. Nevertheless, deeply rooted and emotionally saturated misbeliefs with historical-cultural origins still prevail. This article focuses on the prehypnotic phase of therapy and proposes remythification to deal with the myth of hypnosis. This approach aims to promote the hypnotherapeutic process by utilizing myth-related misconceptions.

Economic Impacts of Climate Change on Winter Tourism: Challenges for Ski Area Operators

NASA Astrophysics Data System (ADS)

Damm, A.; Köberl, J.; Prettenthaler, F.; Töglhofer, C.

2012-04-01

Increasing temperatures and snow scarce winter seasons pose a big challenge for the winter tourism industry. Changing natural snow reliability influences tourism demand and ski area operators are faced with an enhanced need of technical snow production. The goal of the present research work is to analyze the economic effects of technical snow production under future climate conditions. Snowmaking as an adaptation strategy to climate change impacts on the ski tourism industry is already taken into consideration in several studies from a scientific perspective concerning snowmaking potentials under future climate conditions and the impacts on ski season length (e.g. Scott et al. 2003; Scott & McBoyle 2007; Hennessy et al. 2008; Steiger 2010). A few studies considered economic aspects of technical snowmaking (e.g. Teich et al. 2007; Gonseth 2008). However, a detailed analysis of the costs and benefits of snowmaking under future climate and snow conditions based on sophisticated climate and snow models has not been carried out yet. The present study addresses the gap of knowledge concerning the economic profitability of prospective snowmaking requirements under future climate scenarios. We carry out a detailed cost-revenue analysis of snowmaking under current and future climate conditions for a case study site in Styria (Austria) using dynamic investment models. The starting point of all economic calculations is the daily demand for artificial snow that determines the requirements for additional snowmaking investments and additional operating costs. The demand for artificial snow is delivered by the snow cover model AMUNDSEN (see Strasser et al. 2011) and is driven by four climate scenarios. Apart from future climate conditions the profitability of snowmaking depends on changes in costs and visitor numbers. The results of a ski tourism demand model analyzing daily visitor numbers and their dependencies of prevailing weather conditions enter the cost-revenue analysis of snowmaking and enable the determination of the immediate benefits in terms of additional revenues of ski ticket sales. Furthermore, we conduct an econometric analysis of how snowmaking investments changed ski ticket prices in previous years, as the positive effects of snowmaking on snow reliability could be offset in the longer term by the effects of higher prices for skiing, possibly resulting in lower demand.

Prevailing Torque Locking Feature in Threaded Fasteners Using Anaerobic Adhesive

NASA Technical Reports Server (NTRS)

Hernandez, Alan; Hess, Daniel P.

2016-01-01

This paper presents results from tests to assess the use of anaerobic adhesive for providing a prevailing torque locking feature in threaded fasteners. Test procedures are developed and tests are performed on three fastener materials, four anaerobic adhesives, and both unseated assembly conditions. Five to ten samples are tested for each combination. Tests for initial use, reuse without additional adhesive, and reuse with additional adhesive are performed for all samples. A 48-hour cure time was used for all initial use and reuse tests. Test data are presented as removal torque versus removal angle with the specification required prevailing torque range added for performance assessment. Percent specification pass rates for the all combinations of fastener material, adhesive, and assembly condition are tabulated and reveal use of anaerobic adhesive as a prevailing torque locking feature is viable. Although not every possible fastener material and anaerobic adhesive combination provides prevailing torque values within specification, any combination can be assessed using the test procedures presented. Reuse without additional anaerobic adhesive generally provides some prevailing torque, and in some cases within specification. Reuse with additional adhesive often provides comparable removal torque data as in initial use.

Similarities in affect, perceived stress, and weight concerns between Black and White women who quit smoking during pregnancy.

Mood and weight concerns may relate to postpartum smoking, and racial differences in these concerns may be important in developing interventions to prevent postpartum relapse. We compared differences in the smoking patterns, mood, and weight concerns of Black and White women who quit smoking during pregnancy (N = 174). In univariate comparisons, there were no consistent differences in nicotine dependence, smoking history, or motivation to remain abstinent postpartum. Moreover, although there were univariate differences in negative affect, smoking for weight control, and eating disinhibition, after controlling for differences in income and educational background between Black and White women, these differences in mood and weight concerns were no longer significant. In our sample of pregnant women who had quit smoking, Black and White women did not differ in mood and weight concerns, two potentially modifiable variables that may affect smoking postpartum relapse.

Parent-Child Interaction Therapy for sexual concerns of maltreated children: A preliminary investigation.

PubMed

Allen, Brian; Timmer, Susan G; Urquiza, Anthony J

2016-06-01

The current study examines whether an evidence-based treatment for externalizing behavior problems may reduce sexual concerns among children with maltreatment histories. An archival analysis identified 44 children between the ages of 3 and 8 exhibiting externalizing problems and co-morbid sexual concerns who were treated using Parent-Child Interaction Therapy (PCIT). A second group of children receiving PCIT for externalizing behaviors without sexual concerns was included for comparison purposes (n=143). Wilcoxon Signed-Ranks Tests indicated significant improvement among the group with sexual concerns, with 63.6% of children no longer displaying clinically significant sexual concerns at post-treatment. In addition, these children showed a decline in general externalizing problems comparable to that observed among the group of children receiving PCIT and not displaying sexual concerns. Lastly, logistic regression analyses showed that pre-treatment posttraumatic stress scores did not moderate improvement of sexual concerns, suggesting that posttraumatic stress-related sexual concerns may improve from PCIT treatment. These findings suggest that evidence-based parent training interventions, specifically PCIT, may successfully reduce sexual concerns among children who experienced maltreatment.

Brazil's Cuiabá- Santarém (BR-163) Highway: the environmental cost of paving a soybean corridor through the Amazon.

PubMed

Fearnside, Philip M

2007-05-01

Brazil's Cuiabá-Santarém (BR-163) Highway provides a valuable example of ways in which decision-making procedures for infrastructure projects in tropical forest areas need to be reformulated in order to guarantee that environmental concerns are properly weighed. BR-163, which is slated to be paved as an export corridor for soybeans via the Amazon River, traverses an area that is largely outside of Brazilian government control. A climate of generalized lawlessness and impunity prevails, and matters related to environment and to land tenure are especially unregulated. Deforestation and illegal logging have accelerated in anticipation of highway paving. Paving would further speed forest loss in the area, as well as stimulate migration of land thieves (grileiros) to other frontiers. An argument is made that the highway should not be reconstructed and paved until after a state of law has been established and it has been independently certified that sufficient governance prevails to secure protected areas and enforce environmental legislation. A waiting period is needed after this is achieved before proceeding with the highway paving. Above all, the logical sequence of steps must be followed, whereby environmental costs are assessed, reported, and weighed prior to making de facto decisions on implementation of infrastructure projects. Deviation from this logical sequence is a common occurrence in many parts of the world, especially in tropical areas.

What Therapies are Favored in the Treatment of the Psychological Sequelae of Trauma in Human Trafficking Victims?

2018-03-01

Human trafficking is a major public health concern that brings about deleterious psychological consequences and sequelae. Although a number of risk and protective factors for the health consequences of human trafficking victims have been identified, there is a dearth of information in the area of treatment. Specifically, we found no articles comparing the different components of prevailing trauma treatment strategies, and the potential usefulness of these strategies in the treatment of human trafficking victims. To this end, we compared and contrasted the different therapeutic treatments typically implemented with victims of trauma (including domestic violence victims and torture victims), and discussed how the different components of these treatments may or may not be helpful for human trafficking victims. We assessed the impact of these treatments on the psychological consequences of trauma and, in particular on posttraumatic stress disorder. We also assessed the potential usefulness of these treatments with co-occurring problems such as substance use, psychosis, dissociation, and other mood and anxiety disorders. On the basis of the prevailing research, we highlighted cognitive therapies as being preferred in addressing the needs of human trafficking victims. Mental health providers who work with human trafficking victims should become aware of and practiced in the use of cognitive therapeutic approaches in treating this population. Efficacy and effectiveness studies are needed to validate our recommendations.

Implementation of a competency assessment tool for agency nurses working in an acute paediatric setting.

PubMed

Hennerby, Cathy; Joyce, Pauline

2011-03-01

This paper reports on the implementation of a competency assessment tool for registered general agency nurses working in an acute paediatric setting, using a change management framework. The increased number of registered general agency nurses working in an acute children's hospital alerted concerns around their competency in working with children. These concerns were initially raised via informal complaints about 'near misses', parental dissatisfaction, perceived competency weaknesses and rising cost associated with their use. [Young's (2009) Journal of Organisational Change, 22, 524-548] nine-stage change framework was used to guide the implementation of the competency assessment tool within a paediatric acute care setting. The ongoing success of the initiative, from a nurse manager's perspective, relies on structured communication with the agency provider before employing competent agency nurses. Sustainability of the change will depend on nurse managers' persistence in attending the concerns of those resisting the change while simultaneously supporting those championing the change. These key communication and supporting roles highlight the pivotal role held by nurse managers, as gate keepers, in safe-guarding children while in hospital. Leadership qualities of nurse managers will also be challenged in continuing to manage and drive the change where resistance might prevail. © 2011 The Authors.

Alcoholics' and nonalcoholics' attributions of control of future life events.

PubMed

Wright, M H; Obitz, F W

1984-03-01

Alcoholic and nonalcoholic subjects rated the degree of control that they and others possess over future life events. Alcoholics attributed less personal control over events to themselves than nonalcoholics did. Alcoholics also attributed less control to themselves than to others, whereas nonalcoholics attributed more control to themselves than to others. These differences prevailed despite the similar socioeconomic and demographic characteristics, recent life experiences and beliefs concerning the general controllability of events of both alcoholics and nonalcoholics. The attributions of alcoholics were consistent with others' notions of self-handicapping. The attributions of nonalcoholics were consistent with control motivation. Alcoholics who attributed less control to themselves than to others more frequently failed to complete treatment than did alcoholics who attributed more control to themselves.

Ionospheric Composition and Reactions: Our present knowledge of what ions are in the ionosphere, and why, is summarized.

PubMed

Donahue, T M

1968-02-02

Recent measurements of ion densities in the ionosphere seem to be more or less compatible with current data for ion-molecule reaction rates in some parts of the ionosphere under conditions in which a steady state prevails. There is no such agreement for the upper ionosphere, where the densities of He(+) and H(+) are difficult to understand in terms of present concepts concerning the relevant production and loss processes. Sources of ionizing radiation are needed to explain night- time observations in the E region and perhaps also in the F region. The D region remains a poorly understood laboratory of negative-ion and positiveion chemistry, where neither observation nor theory is as yet adequate.

Slow changing postural cues cancel visual field dependence on self-tilt detection.

PubMed

Scotto Di Cesare, C; Macaluso, T; Mestre, D R; Bringoux, L

2015-01-01

Interindividual differences influence the multisensory integration process involved in spatial perception. Here, we assessed the effect of visual field dependence on self-tilt detection relative to upright, as a function of static vs. slow changing visual or postural cues. To that aim, we manipulated slow rotations (i.e., 0.05° s(-1)) of the body and/or the visual scene in pitch. Participants had to indicate whether they felt being tilted forward at successive angles. Results show that thresholds for self-tilt detection substantially differed between visual field dependent/independent subjects, when only the visual scene was rotated. This difference was no longer present when the body was actually rotated, whatever the visual scene condition (i.e., absent, static or rotated relative to the observer). These results suggest that the cancellation of visual field dependence by dynamic postural cues may rely on a multisensory reweighting process, where slow changing vestibular/somatosensory inputs may prevail over visual inputs.

Effect of Ring Strain on the Charge Transport of a Robust Norbornadiene–Quadricyclane-Based Molecular Photoswitch

PubMed Central

2017-01-01

Integrating functional molecules into single-molecule devices is a key step toward the realization of future computing machines based on the smallest possible components. In this context, photoswitching molecules that can make a transition between high and low conductivity in response to light are attractive candidates. Here we present the synthesis and conductance properties of a new type of robust molecular photothermal switch based on the norbornadiene (NB)–quadricyclane (QC) system. The transport through the molecule in the ON state is dominated by a pathway through the π-conjugated system, which is no longer available when the system is switched to the OFF state. Interestingly, in the OFF state we find that the same pathway contributes only 12% to the transport properties. We attribute this observation to the strained tetrahedral geometry of the QC. These results challenge the prevailing assumption that current will simply flow through the shortest through-bond path in a molecule. PMID:28408968

Effects of thermal fluctuations and fluid compressibility on hydrodynamic synchronization of microrotors at finite oscillatory Reynolds number: a multiparticle collision dynamics simulation study.

PubMed

Theers, Mario; Winkler, Roland G

2014-08-28

We investigate the emergent dynamical behavior of hydrodynamically coupled microrotors by means of multiparticle collision dynamics (MPC) simulations. The two rotors are confined in a plane and move along circles driven by active forces. Comparing simulations to theoretical results based on linearized hydrodynamics, we demonstrate that time-dependent hydrodynamic interactions lead to synchronization of the rotational motion. Thermal noise implies large fluctuations of the phase-angle difference between the rotors, but synchronization prevails and the ensemble-averaged time dependence of the phase-angle difference agrees well with analytical predictions. Moreover, we demonstrate that compressibility effects lead to longer synchronization times. In addition, the relevance of the inertia terms of the Navier-Stokes equation are discussed, specifically the linear unsteady acceleration term characterized by the oscillatory Reynolds number ReT. We illustrate the continuous breakdown of synchronization with the Reynolds number ReT, in analogy to the continuous breakdown of the scallop theorem with decreasing Reynolds number.

Gender and globalization. A century in retrospect.

PubMed

Chinkin, C

2000-01-01

In the past, power structures of the nation-State have been organized around patriarchal assumptions, granting men monopoly over power, authority, and wealth. A number of structures have been erected to achieve this imbalance, which have disguised its inequity by making it appear as natural and universal. However, with globalization, this centralization of power within the Sovereign State has been fragmented. Although globalization opens up new spaces by weakening the nation-State, subsequently making possible the undermining of traditional gender hierarchies and devising new bases for gender relations, the reality that the State is no longer the sole institution that can define identity and belonging within it has denied women the space to assert their own claims to gendered self-determination. In this regard, globalization has impacted upon gender relations in complex and contradictory ways. This paper discusses such impacts of globalization on gender relations. Overall, it has become apparent that forms of inequality still exist regardless of a State's prevailing political ideology. Their manifestations may differ, but the reality of women's subordination remains constant.

This study presents the first well-dated high resolution stable isotope (δ18 O and δ13 C) and trace element (Mg and Sr) speleothem records from southwestern Morocco covering the last 1000 yrs. Our records reveal substantial decadal to multidecadal swings between dry and humid periods, consistent with regional paleorecords with prevailing dry conditions during the Medieval Climate Anomaly (MCA), wetter conditions during the second part of the Little Ice Age (LIA), and a trend towards dry conditions during the current warm period. These coherent regional climate signals suggest common climate controls. Statistical analyses indicate that the climate of southwestern Morocco remained under the combined influence of both the North Atlantic Oscillation (NAO) and the Atlantic Multidecadal Oscillation (AMO) over the last millennium. Interestingly, the generally warmer MCA and colder LIA at longer multidecadal timescales probably influenced the regional climate in North Africa through the influence on Sahara Low which weakened and strengthened the mean moisture inflow from the Atlantic Ocean during the MCA and LIA respectively.

Populations of Escherichia coli Z905/pPHL7, a transgenic microorganism, were heterogenic in the expression of plasmid genes when adapting to the conditions of water microcosms of various mineralization levels and structure of microbial community. This TM has formed two subpopulations (ampicillin-resistant and ampicillin-sensitive) in every microcosm. Irrespective of mineralization level of a microcosm, when E. coli Z905/pPHL7 alone was introduced, the ampicillin-resistant subpopulation prevailed, while introduction of the TM together with indigenous bacteria led to the dominance of the ampicillin-sensitive subpopulation. A high level of lux gene expression maintained longer in the freshwater microcosms than in sterile saline lake water microcosms. A horizontal gene transfer has been revealed between the jointly introduced TM and Micrococcus sp. 9/pSH1 in microcosms with the Lake Shira sterile water. c2005 COSPAR. Published by Elsevier Ltd.

Intestinal worm infections, including roundworm, hookworm, and whipworm, are major international health concerns, affecting approximately one fourth of the world's population. Many intervention schemes have been attempted to control these infections in heavily exposed populations, but success has been limited because individuals are readily reinfected upon renewed exposure. Few data are available concerning people's health beliefs about soil-transmitted helminthic infections in such populations. The purpose of this study was to assess health beliefs about common helminthiasis in a population experiencing moderate to high rates of infection. The focal population for the study was the Jirel population, a tribal group distributed across nine villages in the Jiri Region of Dolakha District, eastern Nepal. The results indicate that beliefs about the types, causes, and treatments of helminthic infections have been developed and reinforced by experience and empirical evidence. People's frequent inability to confirm the efficacy of drug therapy by observing worms in stools has led to dissatisfaction with biomedical approaches. Carefully planned education programs are required to alter prevailing attitudes and improve control of soil-transmitted helminthiasis in the region.

At the time of writing, the Italian Parliament is debating a new law that would make it legal to practice an unproven stem cell treatment in public hospitals. The treatment, offered by a private non-medical organization, may not be safe, lacks a rationale, and violates current national laws and European regulations. This case raises multiple concerns, most prominently the urgent need to protect patients who are severely ill, exposed to significant risks, and vulnerable to exploitation. The scientific community must consider the context—social, financial, medical, legal—in which stem cell science is currently situated and the need for stringent regulation. Additional concerns are emerging. These emanate from the novel climate, created within science itself, and stem cell science in particular, by the currently prevailing model of ‘translational medicine'. Only rigorous science and rigorous regulation can ensure translation of science into effective therapies rather than into ineffective market products, and mark, at the same time, the sharp distinction between the striving for new therapies and the deceit of patients.

Perception and Cognition Are Largely Independent, but Still Affect Each Other in Systematic Ways: Arguments from Evolution and the Consciousness-Attention Dissociation

PubMed Central

Montemayor, Carlos; Haladjian, Harry H.

2017-01-01

The main thesis of this paper is that two prevailing theories about cognitive penetration are too extreme, namely, the view that cognitive penetration is pervasive and the view that there is a sharp and fundamental distinction between cognition and perception, which precludes any type of cognitive penetration. These opposite views have clear merits and empirical support. To eliminate this puzzling situation, we present an alternative theoretical approach that incorporates the merits of these views into a broader and more nuanced explanatory framework. A key argument we present in favor of this framework concerns the evolution of intentionality and perceptual capacities. An implication of this argument is that cases of cognitive penetration must have evolved more recently and that this is compatible with the cognitive impenetrability of early perceptual stages of processing information. A theoretical approach that explains why this should be the case is the consciousness and attention dissociation framework. The paper discusses why concepts, particularly issues concerning concept acquisition, play an important role in the interaction between perception and cognition. PMID:28174551

An alert system for triggering different levels of coastal management urgency: Tunisia case study using rapid environmental assessment data.

Rapid environmental assessment (REA) involves scoring abundances of ecosystems/species groups and magnitude of pressures, concurrently, using the same logarithmic (0-6) assessment scale. We demonstrate the utility of REA data for an alert system identifying different levels of coastal management concern. Thresholds set for abundances/magnitudes, when crossed, trigger proposed responses. Kerkennah, Tunisia, our case study, has significant natural assets (e.g. exceptional seagrass and invertebrate abundances), subjected to varying levels of disturbance and management concern. Using REA thresholds set, fishing, green algae/eutrophication and oil occurred at 'low' levels (scores 0-1): management not (currently) necessary. Construction and wood litter prevailed at 'moderate' levels (scores 2-4): management alerted for (further) monitoring. Solid waste densities were 'high' (scores 5-6): management alerted for action; quantities of rubbish were substantial (20-200 items m⁻¹ beach) but not unprecedented. REA is considered a robust methodology and complementary to other rapid assessment techniques, environmental frameworks and indicators of ecosystem condition. Copyright © 2014 Elsevier Ltd.

Impact of molecular flexibility on binding strength and self-sorting of chiral π-surfaces.

In this work, we have explored for the first time the influence of conformational flexibility of π-core on chiral self-sorting properties of perylene bisimides (PBIs) that are currently one of the most prominent classes of functional dyes. For this purpose, two series of chiral macrocyclic PBIs 3a-c and 4a-c comprising oligoethylene glycol bridges of different lengths at the 1,7 bay positions were synthesized and their atropo-enantiomers (P and M enantiomers) were resolved. Single crystal analysis of atropo-enantiomerically pure (P)-3a not only confirmed the structural integrity of the ethylene glycol bridged macrocycle but also illustrated the formation of π-stacked dimers with left-handed supramolecular helicity. Our detailed studies with the series of highly soluble chiral PBIs 4a-c by 1- and 2-D (1)H NMR techniques, and temperature- and concentration-dependent UV/vis absorption and circular dichroism (CD) spectroscopy revealed that in π-π-stacking dimerization of these PBIs chiral self-recognition (i.e., PP and MM homodimer formation) prevails over self-discrimination (i.e., PM heterodimer formation). Our studies clearly showed that with increasing conformational flexibility of PBI cores imparted by longer bridging units, the binding strength for the dimerization process increases, however, the efficiency for chiral self-recognition decreases. These results are rationalized in terms of an induced-fit mechanism facilitating more planarized π-scaffolds of PBIs containing longer bridging units upon π-π-stacking.

Deep geothermal: The ‘Moon Landing’ mission in the unconventional energy and minerals space

2015-01-30

Deep geothermal from the hot crystalline basement has remained an unsolved frontier for the geothermal industry for the past 30 years. This poses the challenge for developing a new unconventional geomechanics approach to stimulate such reservoirs. While a number of new unconventional brittle techniques are still available to improve stimulation on short time scales, the astonishing richness of failure modes of longer time scales in hot rocks has so far been overlooked. These failure modes represent a series of microscopic processes: brittle microfracturing prevails at low temperatures and fairly high deviatoric stresses, while upon increasing temperature and decreasing applied stressmore » or longer time scales, the failure modes switch to transgranular and intergranular creep fractures. Accordingly, fluids play an active role and create their own pathways through facilitating shear localization by a process of time-dependent dissolution and precipitation creep, rather than being a passive constituent by simply following brittle fractures that are generated inside a shear zone caused by other localization mechanisms. We lay out a new paradigm for reservoir stimulation by reactivating pre-existing faults at reservoir scale in a reservoir scale aseismic, ductile manner. A side effect of the new “soft” stimulation method is that owing to the design specification of a macroscopic ductile response, the proposed method offers the potential of a safer control over the stimulation process compared to conventional stimulation protocols such as currently employed in shale gas reservoirs.« less

We investigated the impact of skeletal-related events (SREs) on health-related quality of life (HRQoL) in patients with metastatic castration-resistant prostate cancer (mCRPC) in phase III trials of enzalutamide versus placebo. Patients with mCRPC experiencing at least one SRE during AFFIRM and PREVAIL were assessed for trajectory-adjusted mean change in HRQoL by first SRE using Functional Assessment of Cancer Therapy-Prostate (FACT-P; AFFIRM, three domains, and PREVAIL, nine domains) and EQ-5D (PREVAIL) instruments. First SREs caused HRQoL deterioration in both trials. Spinal cord compression had the largest impact, with clinically meaningful reductions in seven of nine FACT-P domains in PREVAIL and all three in AFFIRM (mean (95% confidence interval (CI)) change in FACT-P total score -16.95 (-26.47, -7.44) and -9.69 (-16.10, -3.27), respectively). In PREVAIL, first SREs caused clinically meaningful declines in EQ-5D utility index, irrespective of category; spinal cord compression had the largest impact (mean (95% CI) change -0.24 (-0.39, -0.08)). In AFFIRM, FACT-P and FACT-General total scores showed clinically meaningful declines after radiation/surgery to bone. SREs were associated with clinically meaningful functional declines in the daily lives of patients with mCRPC. Spinal cord compression had the largest impact on HRQoL.

PREVAIL - Projection Reduction Exposure with Variable Axis Immersion Lenses represents the high throughput e-beam projection approach to NGL which IBM is pursuing in cooperation with Nikon Corporation as alliance partner. This paper discusses the challenges and accomplishments of the PREVAIL project. The supreme challenge facing all e-beam lithography approaches has been and still is throughput. Since the throughput of e-beam projection systems is severely limited by the available optical field size, the key to success is the ability to overcome this limitation. The PREVAIL technique overcomes field-limiting off-axis aberrations through the use of variable axis lenses, which electronically shift the optical axis simultaneously with the deflected beam so that the beam effectively remains on axis. The resist images obtained with the Proof-of-Concept (POC) system demonstrate that PREVAIL effectively eliminates off- axis aberrations affecting both resolution and placement accuracy of pixels. As part of the POC system a high emittance gun has been developed to provide uniform illumination of the patterned subfield and to fill the large numerical aperture projection optics designed to significantly reduce beam blur caused by Coulomb interaction.

Racial and ethnic disparities in dental care for publicly insured children.

PubMed

Pourat, Nadereh; Finocchio, Len

2010-07-01

Poor oral health has important implications for the healthy development of children. Children in Medicaid, especially Latinos and African Americans, experience high rates of tooth decay, yet they visit dentists less often than privately insured children. Even Latino and African American children with private insurance are less likely than white children to visit dentists and have longer intervals between dental visits. Furthermore, Latino and African American children in Medicaid are more likely than white children in Medicaid to have longer intervals between visits. These findings raise concerns about Medicaid's ability to address disparities in dental care access and, more broadly, in health care.

Skeletal-related events significantly impact health-related quality of life in metastatic castration-resistant prostate cancer: data from PREVAIL and AFFIRM trials

2017-01-01

Background: We investigated the impact of skeletal-related events (SREs) on health-related quality of life (HRQoL) in patients with metastatic castration-resistant prostate cancer (mCRPC) in phase III trials of enzalutamide versus placebo. Methods: Patients with mCRPC experiencing at least one SRE during AFFIRM and PREVAIL were assessed for trajectory-adjusted mean change in HRQoL by first SRE using Functional Assessment of Cancer Therapy-Prostate (FACT-P; AFFIRM, three domains, and PREVAIL, nine domains) and EQ-5D (PREVAIL) instruments. Results: First SREs caused HRQoL deterioration in both trials. Spinal cord compression had the largest impact, with clinically meaningful reductions in seven of nine FACT-P domains in PREVAIL and all three in AFFIRM (mean (95% confidence interval (CI)) change in FACT-P total score –16.95 (–26.47, –7.44) and –9.69 (–16.10, –3.27), respectively). In PREVAIL, first SREs caused clinically meaningful declines in EQ-5D utility index, irrespective of category; spinal cord compression had the largest impact (mean (95% CI) change –0.24 (–0.39, –0.08)). In AFFIRM, FACT-P and FACT-General total scores showed clinically meaningful declines after radiation/surgery to bone. Conclusions: SREs were associated with clinically meaningful functional declines in the daily lives of patients with mCRPC. Spinal cord compression had the largest impact on HRQoL. PMID:28045115

Antibodies, synthetic peptides and related constructs for planetary health based on green chemistry in the Anthropocene.

PubMed

Caoili, Salvador Eugenio

2018-03-01

The contemporary Anthropocene is characterized by rapidly evolving complex global challenges to planetary health vis-a-vis sustainable development, yet innovation is constrained under the prevailing precautionary regime that regulates technological change. Small-molecule xenobiotic drugs are amenable to efficient large-scale industrial synthesis; but their pharmacokinetics, pharmacodynamics, interactions and ultimate ecological impact are difficult to predict, raising concerns over initial testing and environmental contamination. Antibodies and similar agents can serve as antidotes and drug buffers or vehicles to address patient safety and decrease dosing requirements. More generally, peptidic agents including synthetic peptide-based constructs exemplified by vaccines can be used together with or instead of nonpeptidic xenobiotics, thus enabling advances in planetary health based on principles of green chemistry from manufacturing through final disposition.

Hemorrhoidectomy - making sense of the surgical options.

PubMed

Yeo, Danson; Tan, Kok-Yang

2014-12-07

While debate continues as to which is the best surgical method for the treatment of hemorrhoids, none of the currently available surgical methods approach the ideal surgical option, which is one that is effective while being safe and painless. In reality, the less painful the procedure, the more likely it is to be associated with recurrence post-op. Where hemorrhoids surgery is concerned, there isn't a "one size fits all" option. Most of the randomized controlled trials performed to date include hemorrhoids of various grades and with a focus on only comparing surgical methods while failing to stratify the outcomes according to the grade of hemorrhoid. We believe that surgery needs to be tailored not only to the grade of the hemorrhoids, but also to the size, circumferential nature of the disease, and prevailing symptomatology.

Junking Good Science: Undoing Daubert v Merrill Dow Through Cross-Examination and Argument

PubMed Central

Givelber, Daniel; Strickler, Lori

2006-01-01

For more than 40 years, the tobacco industry prevailed in lawsuits brought by injured smokers, despite overwhelming epidemiological evidence that smoking caused lung cancer. Tobacco lawyers were able to create doubt about causation. They sought to persuade jurors that “everybody knew” smoking was harmful but “nobody knows” what causes cancer by recreating in court the scientific debate resolved by the 1964 Surgeon General’s Report. The particularistic structure of jury trials combined with the law’s mechanistic view of causation enables a defendant to contest virtually any claim concerning disease causation. Despite judicial efforts to eliminate “junk science” from lawsuits, a well-financed defendant may succeed in persuading jurors of the epidemiological equivalent of the proposition that the earth is flat.

Strong-smelling plant extracts, such as essential oils, have a variety of feeding effects on mammals. Considering current concerns over long-term health issues and environmental effects of chemicals, plant-based products with repellent or antifungal activities may represent good solutions for improvement of rodent pest control programs. The present study was therefore focused on examining the effects of bergamot, lavender, and thyme essential oils as additional bait components on daily intakes of cereal-based baits by wild house mice. Lavender essential oil, containing linalool and linalyl acetate as main components, and thyme essential oil with a prevailing thymol component had no effects on house mice diet. Bergamot essential oil, whose main components were linalool, limonene, and linalyl acetate, showed a repellent effect on house mouse diet.

To determine the prevalence of refractive errors in 7 and 8 year-old schoolchildren in the province of Western Pomerania. 140 pupils of elementary schools were examined. Measurements of visual acuity and retinoscopy after cycloplegia were carried out. Prevalence of hyperopia, myopia, and astigmatism was 76.1%, 3.3% and 5.1%, respectively. No statistically significant differences between 7 and 8 year-old children were found. 1. There is a relatively high prevalence of refractive errors, with hyperopia prevailing, among 7 and 8 year-old schoolchildren. 2. Myopia in young children is a cause for concern an further studies. 3. High prevalence of refractive errors in children calls for systematic examination and focused interviewing by medical professionals of the school health care system.

Community perceptions of intimate partner violence - a qualitative study from urban Tanzania

PubMed Central

2011-01-01

Background Intimate partner violence against women is a prevailing public health problem in Tanzania, where four of ten women have a lifetime exposure to physical or sexual violence by their male partners. To be able to suggest relevant and feasible community and health care based interventions, we explored community members' understanding and their responses to intimate partner violence. Methods A qualitative study using focus group discussions with 75 men and women was conducted in a community setting of urban Tanzania. We analysed data using a grounded theory approach and relate our findings to the ecological framework of intimate partner violence. Results The analysis resulted in one core category, "Moving from frustration to questioning traditional gender norms", that denoted a community in transition where the effects of intimate partner violence had started to fuel a wish for change. At the societal level, the category "Justified as part of male prestige" illustrates how masculinity prevails to justify violence. At the community level, the category "Viewed as discreditable and unfair" indicates community recognition of intimate partner violence as a human rights concern. At the relationship level, the category "Results in emotional entrapment" shows the shame and self-blame that is often the result of a violent relationship. At the individual level, the risk factors for intimate partner violence were primarily associated with male characteristics; the category "Fed up with passivity" emerged as an indication that community members also acknowledge their own responsibility for change in actions. Conclusions Prevailing gender norms in Tanzania accept women's subordination and justify male violence towards women. At the individual level, an increasing openness makes it possible for women to report, ask for help, and become proactive in suggesting preventive measures. At the community level, there is an increased willingness to intervene but further consciousness-raising of the human rights perspective of violence, as well as actively engaging men. At the macro level, preventive efforts must be prioritized through re-enforcement of legal rights, and provision of adequate medical and social welfare services for both survivors and perpetrators.

Particulate contamination is of concern in a variety of environments. This issue is especially important in confined spaces with highly controlled atmospheres such as space exploration vehicles involved in extraterrestrial surface missions. Lunar dust was a significant challenge for the Apollo astronauts and will be of greater concern for longer duration, future missions. Passive mitigation strategies, those not requiring external energy, may decrease some of these concerns, and have been investigated in this work. A myriad of approaches to modify the surface chemistry and topography of a variety of substrates was investigated. These involved generation of novel materials, photolithographic techniques, and other template approaches. Additionally, single particle and multiple particle methods to quantitatively evaluate the particle-substrate adhesion interactions were developed.

Professional liability insurance and medical error disclosure.

PubMed

McLennan, Stuart; Shaw, David; Leu, Agnes; Elger, Bernice

2015-01-01

To examine medicolegal stakeholders' views about the impact of professional liability insurance in Switzerland on medical error disclosure. Purposive sample of 23 key medicolegal stakeholders in Switzerland from a range of fields between October 2012 and February 2013. Data were collected via individual, face-to-face interviews using a researcher-developed semi-structured interview guide. Interviews were transcribed and analysed using conventional content analysis. Participants, particularly those with a legal or quality background, reported that concerns relating to professional liability insurance often inhibited communication with patients after a medical error. Healthcare providers were reported to be particularly concerned about losing their liability insurance cover for apologising to harmed patients. It was reported that the attempt to limit the exchange of information and communication could lead to a conflict with patient rights law. Participants reported that hospitals could, and in some case are, moving towards self-insurance approaches, which could increase flexibility regarding error communication The reported current practice of at least some liability insurance companies in Switzerland of inhibiting communication with harmed patients after an error is concerning and requires further investigation. With a new ethic of transparency regarding medical errors now prevailing internationally, this approach is increasingly being perceived to be misguided. A move away from hospitals relying solely on liability insurance may allow greater transparency after errors. Legalisation preventing the loss of liability insurance coverage for apologising to harmed patients should also be considered.

Man in the age of technology.

PubMed

Galimberti, Umberto

2009-02-01

This paper argues that technology is no longer merely a tool for man's use but has become the environment in which man undergoes modifications. The author traces the role of technology from the Greeks to the present day. For the Greeks, Nature was governed by necessity and therefore unchangeable whereas in the Judeo-Christian tradition, nature was entrusted to man for him to dominate. Modern science studies the world in order to manipulate and dominate nature through the use of technology which has now become an end in itself, governing the solution of political problems and confronting us with problems beyond our competence to resolve. The ethical impact of technology has been to create a change from 'acting' which assumes responsibility for one's actions to 'doing' which is concerned only with the effective execution of a 'job' without concern for the wider consequences. It can no longer be argued that technology is good or bad according to the use we make of it since technology now makes use of us and thus transforms our ethics, social relationships and psychological being.

2013 Immune Risk Standing Review Panel Research Plan Review for: The Risk of Crew Adverse Health Event Due to Altered Immune Response

NASA Technical Reports Server (NTRS)

Steinberg, Susan

2014-01-01

The 2013 Immune Risk Standing Review Panel (from here on referred to as the SRP) participated in a meeting with representatives from the Human Research Program (HRP) Human Health Countermeasures (HHC) Element and HRP management on February 3-4, 2014 in Houston, TX to review the updated Research Plan for the Risk of Crew Adverse Health Event Due to Altered Immune Response in the HRP Integrated Research Plan. The SRP is impressed with the work the immune discipline has done since the 2012 SRP review and agrees with the new wording of the Gaps, no longer questions, now statements. The SRP also likes the addition of adding targets for closing the Gaps, but it is not clear how they got to some of the interim stages (interval percentages). A major concern that the SRP has mentioned since the initial 2009 SRP meeting is that there is still not enough emphasis on the interdisciplinary aspect of the immune risk associated with other risks (i.e., nutrition, radiation, etc.). The SRP recommends that a "translational SRP" or advisory group be developed that is composed of members from all of the HRP SRPs. The SRP also thinks that the immune discipline should consider a more systems biology approach. Lastly, the SRP is concerned that the risks observed in research from low Earth orbit (LEO) missions may not accurately reflect all the risks of longer duration flight beyond LEO. Also, there does not seem to be a concern for immune responses that may occur when someone is in space longer than six months, for example, a Mars mission would take three years. The absence of disease in past and current flight scenarios does not mean the risk may not be there in future flight settings.

Honorable son might be a girl: social effects of China's one-child policy.

PubMed

Wu, D Y

1984-01-01

The population growth of China continues to outpace economic production despite a tremendous decrease in fertility rates in the last decade. The dual goals of modernization and population control now hinge on the success of the government's policy of 1-child families. Limiting couples to 1 child appears to be a simple and effective way of achieving the goal of 1.2 billion population by 2020, but closer examination suggests that success in population control could mean social and cultural problems. Is the "onyl child" raised radically different from the child who grows up with siblings? The predominant view is that child rearinfg in China has become too soft. Based on equal parts of observation abd speculation, the prevailing wisdom contends that the only child runs the risk of becoming a self-centered, demanding, uncooperative, and materialistic adult who lacks self-discipline and has no interest in serving others. Single children appear to have more "bad habits", yet preliminary testing in a few kindergartens shows them to faster learners and intellectually moe mature. By directing their resources and attention on 1 child, parents are better able to provide better nutrition and living conditions. Yet, concentrated parental expectations and pressure to succeed may result in mental health complications for the only child. To counteract the effects of 1-child families and their fostering of individualism, institutional child rearing at the nursery and kindergarten levels is emphasized. However, parents seeing their child only 1 day a week, may overcompensate for the time of separation, teaching the child a double standard concerning school values vs. home values. Future residential arrangements for elderly parents and grandparents will create problems for the only child. Another prevailing problem is the traditional Chinese preference for male children, particularly in rural areas. Discrimination against females has become a serious problem in the countryside, and infanticide of girl babies has been reported in several villages. This causes an imbalance in the male/female ratio that is so prominent in some areas that the number of potential brides is of serious concern.

[Clinical experiences with Climen in peri- and postmenopausal women].

Husmann, F

1997-01-01

42 women with signs of androgenization were treated with Climen in the peri- and postmenopause for a period longer than 12 months. The effect on most typical climacteric syndromes was comparable to other free available compounds. Concerning our patients, Climen was more effective than other compounds. In no case the withdrawal of Climen due to side-effects was necessary. Surprisingly an androgenetical loss of hair was stopped in 9 out of 10 cases. Climen widens essentially the therapeutical possibilities concerning hormone replacement in peri- and postmenopausal women and should not only be used in women with signs of androgenization.

Short-lived infected cells support virus replication in sooty mangabeys naturally infected with simian immunodeficiency virus: implications for AIDS pathogenesis.

2008-04-01

Sooty mangabeys (SMs) naturally infected with simian immunodeficiency virus (SIV) do not develop AIDS despite high levels of virus replication. At present, the mechanisms underlying this disease resistance are poorly understood. Here we tested the hypothesis that SIV-infected SMs avoid immunodeficiency as a result of virus replication occurring in infected cells that live significantly longer than human immunodeficiency virus (HIV)-infected human cells. To this end, we treated six SIV-infected SMs with potent antiretroviral therapy (ART) and longitudinally measured the decline in plasma viremia. We applied the same mathematical models used in HIV-infected individuals and observed that SMs naturally infected with SIV also present a two-phase decay of viremia following ART, with the bulk (92 to 99%) of virus replication sustained by short-lived cells (average life span, 1.06 days), and only 1 to 8% occurring in longer-lived cells. In addition, we observed that ART had a limited impact on CD4(+) T cells and the prevailing level of T-cell activation and proliferation in SIV-infected SMs. Collectively, these results suggest that in SIV-infected SMs, similar to HIV type 1-infected humans, short-lived activated CD4(+) T cells, rather than macrophages, are the main source of virus production. These findings indicate that a short in vivo life span of infected cells is a common feature of both pathogenic and nonpathogenic primate lentivirus infections and support a model for AIDS pathogenesis whereby the direct killing of infected cells by HIV is not the main determinant of disease progression.

Sooty mangabeys (SMs) naturally infected with simian immunodeficiency virus (SIV) do not develop AIDS despite high levels of virus replication. At present, the mechanisms underlying this disease resistance are poorly understood. Here we tested the hypothesis that SIV-infected SMs avoid immunodeficiency as a result of virus replication occurring in infected cells that live significantly longer than human immunodeficiency virus (HIV)-infected human cells. To this end, we treated six SIV-infected SMs with potent antiretroviral therapy (ART) and longitudinally measured the decline in plasma viremia. We applied the same mathematical models used in HIV-infected individuals and observed that SMs naturally infected with SIV also present a two-phase decay of viremia following ART, with the bulk (92 to 99%) of virus replication sustained by short-lived cells (average life span, 1.06 days), and only 1 to 8% occurring in longer-lived cells. In addition, we observed that ART had a limited impact on CD4+ T cells and the prevailing level of T-cell activation and proliferation in SIV-infected SMs. Collectively, these results suggest that in SIV-infected SMs, similar to HIV type 1-infected humans, short-lived activated CD4+ T cells, rather than macrophages, are the main source of virus production. These findings indicate that a short in vivo life span of infected cells is a common feature of both pathogenic and nonpathogenic primate lentivirus infections and support a model for AIDS pathogenesis whereby the direct killing of infected cells by HIV is not the main determinant of disease progression.

Urban Water and Riverine Quality: Participatory Science in Singapore

NASA Astrophysics Data System (ADS)

Higgitt, D. L.

2011-12-01

Singapore is a highly urbanised environment experiencing tropical monsoon hydrological regimes. A heavily engineered fluvial system has been developed over time to provide efficient drainage and reduce the area subject to flood risk. However, recent interest in ecosystem-based approaches to river management and the enhancement of the aesthetic and ecological 'quality' of riverine landscape, coupled with concerns about climate change, has challenged the prevailing engineering view. This is reflected in the Public Utility Board (PUB) ABC Waters Programme, which also seeks to develop community interest in riverine environments and engagement with water-related concerns. As part of a programme developing participatory GIS (PGIS) with school and university students, we have undertaken applications involving participant observation, reporting and analysis of water quality data and habitat quality based on a simplified version of the UK Environment Agency's River Habitat Survey. From an educational perspective, there is evidence that these PGIS initiatives raise environmental awareness and enhance geospatial thinking, particularly in relation to catchment management concepts. The extent to which participant-derived data can contribute to a citizen science of urban water quality and hence deliver some aspects of the community engagement sought after by the authorities, is a topic of debate.

Are theories of perception necessary? A review of Gibson's The Ecological Approach to Visual Perception.

PubMed Central

Costall, A P

1984-01-01

Representational theories of perception postulate an isolated and autonomous "subject" set apart from its real environment, and then go on to invoke processes of mental representation, construction, or hypothesizing to explain how perception can nevertheless take place. Although James Gibson's most conspicuous contribution has been to challenge representational theory, his ultimate concern was the cognitivism which now prevails in psychology. He was convinced that the so-called cognitive revolution merely perpetuates, and even promotes, many of psychology's oldest mistakes. This review article considers Gibson's final statement of his "ecological" alternative to cognitivism (Gibson, 1979). It is intended not as a complete account of Gibson's alternative, however, but primarily as an appreciation of his critical contribution. Gibson's sustained attempt to counter representational theory served not only to reveal the variety of arguments used in support of this theory, but also to expose the questionable metaphysical assumptions upon which they rest. In concentrating upon Gibson's criticisms of representational theory, therefore, this paper aims to emphasize the point of his alternative scheme and to explain some of the important concerns shared by Gibson's ecological approach and operant psychology.

An overview on safety issues related to erythropoiesis-stimulating agents for the treatment of anaemia in patients with chronic kidney disease.

PubMed

Del Vecchio, Lucia; Locatelli, Francesco

2016-08-01

Erythropoiesis stimulating agents (ESA) are effective drugs, which have been used for decades in patients with chronic kidney disease (CKD) with few side effects. More recently, concern has been raised around their safety, from higher cardiovascular and thrombosis risk to cancer progression and increased mortality. We made a literature search on PubMed looking for adverse effects of ESA in CKD patients. The topics covered are cardiovascular adverse events, thrombosis, increased mortality, hypertension, cancer progression, diabetic retinopathy, pure red cell aplasia and anaphylactic reactions. Concerns around ESA therapy have questioned treatment indications in high-risk CKD patients (those with cancer, diabetes and cardiovascular comorbidities). A more cautious approach has then prevailed. In our opinion, intermediate Hb values (Hb 10-12 g/dl) should be aimed with ESA therapy, being more cautious in high-risk patients. As a consequence, IV iron is administered more frequently. However, excessive iron use may cause iron overload and in rare cases severe anaphylactic reactions. There are expectations of new erythropoietic agents, such as those manipulating the hypoxia-inducible transcription factors (HIF) system. Differing from ESAs, they stimulate the production of endogenous EPO, avoiding over-physiological plasmatic levels.

The nocturnal bottleneck and the evolution of activity patterns in mammals.

Gerkema, Menno P; Davies, Wayne I L; Foster, Russell G; Menaker, Michael; Hut, Roelof A

2013-08-22

In 1942, Walls described the concept of a 'nocturnal bottleneck' in placental mammals, where these species could survive only by avoiding daytime activity during times in which dinosaurs were the dominant taxon. Walls based this concept of a longer episode of nocturnality in early eutherian mammals by comparing the visual systems of reptiles, birds and all three extant taxa of the mammalian lineage, namely the monotremes, marsupials (now included in the metatherians) and placentals (included in the eutherians). This review describes the status of what has become known as the nocturnal bottleneck hypothesis, giving an overview of the chronobiological patterns of activity. We review the ecological plausibility that the activity patterns of (early) eutherian mammals were restricted to the night, based on arguments relating to endothermia, energy balance, foraging and predation, taking into account recent palaeontological information. We also assess genes, relating to light detection (visual and non-visual systems) and the photolyase DNA protection system that were lost in the eutherian mammalian lineage. Our conclusion presently is that arguments in favour of the nocturnal bottleneck hypothesis in eutherians prevail.

Birthweight of Children of Immigrants by Maternal Duration of Residence in the United States

PubMed Central

Teitler, Julien O.; Hutto, Nathan; Reichman, Nancy E.

2012-01-01

A large literature on immigrant health in the U.S. has shown that immigrants tend to be healthier and live longer than both individuals who remain in their countries of origin and natives of their host countries who are of the same race or ethnicity. However, this immigrant health advantage appears to diminish with duration of residence in the U.S. Few studies of the effects of immigrants' exposure to the U.S. have focused on perinatal health. This study used three contemporary national datasets to describe patterns in infant birthweight by maternal duration of residence in the U.S. For both immigrants overall and Hispanic immigrants in particular, rates of low birthweight appeared to decline over the first few years in the U.S. and increase thereafter. This curvilinear association was robust across the three datasets and deviates somewhat from the prevailing notion that health declines monotonically over time. Additionally, we found no evidence that prenatal substance use increased with duration of residence in the U.S. PMID:22580075

[Orthopedics and patients under national socialism dictatorship].

PubMed

Thomann, K D; Rauschmann, M

2001-10-01

The 12-year dictatorship of National Socialism represents a decisive event in the history of orthopedics in Germany. Treatment and care was limited to those patients whose prognosis promised their reintegration into the work force. Those orthopedic patients with mental and psychological handicaps no longer came under the care of orthopedists and were potential candidates for annihilation. Despite concerted efforts to the contrary, as can be gleaned from the lists of topics at the annual meetings, the prevailing political circumstances encumbered scientific activities. The almost total isolation from international contacts had a negative effect. Orthopedists were hindered in their work by the law on sterilization, which provided for sterilization in cases of severe physical deformity. Some orthopedists even considered the presence of hip dysplasia to be an indication. The roles played by Georg Hohmann, Hellmut Eckhardt, Lothar Kreuz, and other leading orthopedists are described in detail. It can be regarded as certain that Hohmann and Eckhardt were able to prevent dire consequences for their orthopedic patients and the profession by cautious tactics. The ethnical problems of involvement with National Socialism are thoroughly discussed.

Annual gonadal cycles in birds: modeling the effects of photoperiod on seasonal changes in GnRH-1 secretion.

PubMed

Dawson, Alistair

2015-04-01

This paper reviews current knowledge of photoperiod control of GnRH-1 secretion and proposes a model in which two processes act together to regulate GnRH1 secretion. Photo-induction controls GnRH1 secretion and is directly related to prevailing photoperiod. Photo-inhibition, a longer term process, acts through GnRH1 synthesis. It progresses each day during daylight hours, but reverses during darkness. Thus, photo-inhibition gradually increases when photoperiods exceed 12h, and reverses under shorter photoperiods. GnRH1 secretion on any particular day is the net result of these two processes acting in tandem. The only difference between species is their sensitivity to photo-inhibition. This can potentially explain differences in timing and duration of breeding seasons between species, why some species become absolutely photorefractory and others relatively photorefractory, why breeding seasons end at the same time at different latitudes within species, and why experimental protocols sometimes produce results that appear counter to what happens naturally.

The effect of latitude on photoperiodic control of gonadal maturation, regression and molt in birds.

PubMed

Dawson, Alistair

2013-09-01

Photoperiod is the major cue used by birds to time breeding seasons and molt. However, the annual cycle in photoperiod changes with latitude. Within species, for temperate and high latitude species, gonadal maturation and breeding start earlier at lower latitudes but regression and molt both occur at similar times at different latitudes. Earlier gonadal maturation can be explained simply by the fact that considerable maturation occurs before the equinox when photoperiod is longer at lower latitudes - genetic differences between populations are not necessary to explain earlier breeding at lower latitudes. Gonadal regression is caused either by absolute photorefractoriness or, in some species with long breeding seasons, relative photorefractoriness. In either case, the timing of regression and molt cannot be explained by absolute prevailing photoperiod or rate of change in photoperiod - birds appear to be using more subtle cues from the pattern of change in photoperiod. However, there may be no difference between absolute and relative photorefractory species in how they utilise the annual cycle in photoperiod to time regression. Copyright © 2013 Elsevier Inc.

Sperm production responds to perceived sperm competition risk in male Drosophila melanogaster.

PubMed

Moatt, Joshua P; Dytham, Calvin; Thom, Michael D F

2014-05-28

Postcopulatory sexual selection arising from female multiple mating leads to the evolution of ejaculates that maximize a male's reproductive success under sperm competition. Where the risk of sperm competition is variable, optimal fitness may be achieved by plastically altering ejaculate characteristics in response to the prevailing sperm competition environment. In the model species Drosophila melanogaster, males expecting to encounter sperm competition mate for longer and transfer more accessory proteins and sperm. Here we show that after being housed with a single rival for one week, the seminal vesicles of male D. melanogaster contain a significantly greater proportion of live sperm than those of males maintained alone, indicating adaptive adjustment of sperm quality in response to the perceived risk of sperm competition. This effect is due to an increase in the number of live sperm produced, indicating that males upregulate sperm production in response to the presence of rivals. Our data suggest that males show plasticity in the rate of spermatogenesis that is adaptive in the context of a fluctuating sperm competition environment. Copyright © 2014 Elsevier Inc.

A taxometric study of hypochondriasis symptoms.

PubMed

Longley, Susan L; Broman-Fulks, Joshua J; Calamari, John E; Noyes, Russell; Wade, Michael; Orlando, Carissa M

2010-12-01

Hypochondriasis has been conceptualized as both a distinct category that is characterized by a disabling illness preoccupation and as a continuum of health concerns. Empirical support for one of these theoretical models will clarify inconsistent assessment approaches and study designs that have impeded theory and research. To facilitate progress, taxometric analyses were conducted to determine whether hypochondriasis is best understood as a discrete category, consistent with the DSM, or as a dimensional entity, consistent with prevailing opinion and most self-report measures. Data from a large undergraduate sample that completed 3 hypochondriasis symptom measures were factor analyzed. The 4 factor analytically derived symptom indicators were then used in these taxometric analyses. Consistent with our hypotheses and existing theory, results supported a dimensional structure for hypochondriasis. Implications for the conceptualization of hypochondriasis and directions for future study are discussed. Copyright © 2010. Published by Elsevier Ltd.

Negligence in securing informed consent and medical malpractice.

PubMed

Perry, C

1988-01-01

The doctrine of informed consent requires that the patient must act voluntarily and in the light of adequate information in order to give legally valid consent to medical care. Different models have been developed by various courts to determine whether the informational requirement, what the physician must disclose to the patient about the potential risks of the proposed treatment, has been met under the tort theory of negligence. To prevail, the patient plaintiff must show that a particular jurisdiction's disclosure standard has been breached, that harm has resulted, and that the defendant physician's negligent failure to discuss certain risks was causally responsible for the patient's failure to withhold consent. Perry discusses possible problems of redundancy or inconsistency concerning the relationship between different models for disclosure and causality, and notes that these problems may have serious implications for patient autonomy.

An Isomer-Specific Approach to Endocrine-Disrupting Nonylphenol in Infant Food.

PubMed

Günther, Klaus; Räcker, Torsten; Böhme, Roswitha

2017-02-15

Nonylphenols (NPs) are persistent endocrine disruptors that are priority hazardous substances of the European Union Water Framework Directive. Their presence in the environment has caused growing concern regarding their impact on human health. Recent studies have shown that nonylphenol is ubiquitous in commercially available foodstuffs and is also present in human blood. The isomer distribution of 4-nonylphenol was analyzed by gas chromatography - mass spectrometry in 44 samples of infant food. Our study shows that the distribution of nonylphenol isomers is dependent on the foodstuff analyzed. Although some isomer groups prevail, different distributions are frequent. Variations are even found in the same food group. Nonylphenol is a complex mixture of isomers, and the estrogenic potentials of each of these isomers are very different. Consequently, to determine the potential toxicological impact of NP in food, an isomer-specific approach is necessary.

Hemorrhoidectomy - making sense of the surgical options

PubMed Central

Yeo, Danson; Tan, Kok-Yang

2014-01-01

While debate continues as to which is the best surgical method for the treatment of hemorrhoids, none of the currently available surgical methods approach the ideal surgical option, which is one that is effective while being safe and painless. In reality, the less painful the procedure, the more likely it is to be associated with recurrence post-op. Where hemorrhoids surgery is concerned, there isn’t a “one size fits all” option. Most of the randomized controlled trials performed to date include hemorrhoids of various grades and with a focus on only comparing surgical methods while failing to stratify the outcomes according to the grade of hemorrhoid. We believe that surgery needs to be tailored not only to the grade of the hemorrhoids, but also to the size, circumferential nature of the disease, and prevailing symptomatology. PMID:25493010

We then turn to explanation: what gender dynamics drive such patterns of work segregation according to sex? Drawing on interviews, we claim that the following stereotypes or prevailing discourses, concerning the distinctive attributes of women and men, may influence such segregation: that women are more caring, supportive and nurturing; that women are better communicators; that women are ‘better organized’; and that men are more creative because they are less bound by rules.

Paleoparasitological Studies on Mummies of the Joseon Dynasty, Korea

Araujo, Adauto; Reinhard, Karl; Chai, Jong Yil

2014-01-01

Paleoparasitology is the application of conventional or molecular investigative techniques to archeological samples in order to reveal parasitic infection patterns among past populations. Although pioneering studies already have reported key paleoparasitological findings around the world, the same sorts of studies had not, until very recently, been conducted in sufficient numbers in Korea. Mummified remains of individuals dating to the Korean Joseon Dynasty actually have proved very meaningful to concerned researchers, owing particularly to their superb preservation status, which makes them ideal subjects for paleoparasitological studies. Over the past several years, our study series on Korean mummies has yielded very pertinent data on parasitic infection patterns prevailing among certain Joseon Dynasty populations. In this short review, we summarized the findings and achievements of our recent paleoparasitological examinations of Joseon mummies and discussed about the prospects for future research in this vein.

1989-04-01

In a maternity clinic the circulation of group B streptococci among the newborns, their mothers and the personnel was established during the period of 1982-1985. Group B streptococci were detected at different biotypes of newborns (the pharynx, the imbilical stump, external suditory meatus, nasal and oral mucosa, eyes and feces), their mothers (the vagina, the perianal area, breast milk, the pharynx, urine, the umbilical cord, amniotic fluid) and in the pharynx of the personnel. In this maternity clinic 15 combinations of type antigens were detected, two combinations (1a/c and 1 b/c) prevailing among them. These results confirmed earlier data concerning two possible ways of transferring infection to newborn infants: vertical, i.e. from the mother to the child during parturition, and nosocomial, i.e. from contaminated newborns or members of the personnel.

We present a brief review of Cosmological Inflation from the personal perspective of the speaker who almost 30 years ago proposed a way of resolving the problem of Cosmological Horizon by employing certain notions and developments from the field of High Energy Physics. Along with a brief introduction of the Horizon and Flatness problems of standard cosmology, this lecture concentrates on personal reminiscing of the notions and ideas that prevailed and influenced the author's thinking at the time. The lecture then touches upon some more recent developments related to the subject including exact solutions to conformal gravity that provide a first principles emergence of a characteristic acceleration in the universe and concludes with some personal views concerning the direction that the cosmology field has taken in the past couple of decades and certain speculations some notions that may indicate future directions of research.

Persistent multi-scale fluctuations shift European hydroclimate to its millennial boundaries.

PubMed

Markonis, Y; Hanel, M; Máca, P; Kyselý, J; Cook, E R

2018-05-02

In recent years, there has been growing concern about the effect of global warming on water resources, especially at regional and continental scales. The last IPCC report on extremes states that there is medium confidence about an increase on European drought frequency during twentieth century. Here we use the Old World Drought Atlas palaeoclimatic reconstruction to show that when Europe's hydroclimate is examined under a millennial, multi-scale perspective, a significant decrease in dryness can be observed since 1920 over most of central and northern Europe. On the contrary, in the south, drying conditions have prevailed, creating an intense north-to-south dipole. In both cases, hydroclimatic conditions have shifted to, and in some regions exceeded, their millennial boundaries, remaining at these extreme levels for the longest period of the 1000-year-long record.

Three-dimensional structure of dominant instabilities in turbulent flow over smooth and rough boundaries

The current status of knowledge regarding coherent vortical structures in turbulent boundary layers and their role in turbulence generation are reviewed. The investigations reported in the study concentrate attention on rough-wall flows prevailing in the geophysical environment and include an experiment determining the three-dimensional form of the turbulence structures linked to the ejection and inrush events observed over rough walls and an experiment concerned with measuring the actual spanwise scale of the near-wall structures for boundary conditions ranging from hydrodynamically smooth to fully rough. It is demonstrated that horseshoe vortical structures are present and play an important role in rough-wall flows and they increase in scale with increasing wall distance, while a dominant spanwise wavelength occurs in the instantaneous cross-flow distribution of streamwise velocity close to the rough wall.

Global and Local Partitioning of the Charge Transferred in the Parr-Pearson Model.

PubMed

Orozco-Valencia, Angel Ulises; Gázquez, José L; Vela, Alberto

2017-05-25

Through a simple proposal, the charge transfer obtained from the cornerstone theory of Parr and Pearson is partitioned, for each reactant, in two channels: an electrophilic, through which the species accepts electrons, and the other, a nucleophilic, where the species donates electrons. It is shown that this global model allows us to determine unambiguously the charge-transfer mechanism prevailing in a given reaction. The partitioning is extended to include local effects through the Fukui functions of the reactants. This local model is applied to several emblematic reactions in organic and inorganic chemistry, and we show that besides improving the correlations obtained with the global model it provides valuable information concerning the atoms in the reactants playing the most important roles in the reaction and thus improving our understanding of the reaction under study.

Despite heightened rates of depression and posttraumatic stress disorder (PTSD) among in Iraq/Afghanistan veterans, the majority of distressed veterans will not receive mental health care. Overcoming barriers to mental health services requires innovative approaches to broaden the reach of evidence-based treatment. The current study examined the efficacy and acceptability of an innovative and dynamic online cognitive-behavioral therapy intervention for PTSD and depression called Vets Prevail. A randomized clinical trial conducted between 2011 and 2013 assessed changes in PTSD and depression in veterans with mild-to-moderate distress. Veterans randomized to Vets Prevail (n = 209) were aged 34.2 ± 7.6 years, mostly male (81.3%), and nonminority (73.7%). Veterans randomized to adjustment as usual (n = 94) were aged 34.7 ± 8.9, mostly male (81.9%), and White (67.0%). Veterans completed the PTSD Checklist-Military Version and the Center for Epidemiological Studies Depression scale (10-item version) postintervention and at 12-week follow-up. Veterans in the Vets Prevail condition reported significantly greater reductions in PTSD, t(250) = 3.24, p = .001 (Mreduction = 5.51, SD = 9.63), and depression, t(252) = 4.37, p = .001 (Mreduction = 2.31, SD = 5.34), at 12-week follow-up compared with veterans in the adjustment as usual condition (PTSD Mreduction = 1.00, SD = 7.32; depression Mreduction = 0.48, SD = 4.95), with moderate effect sizes for PTSD (Cohen's d = 0.42) and depression (Cohen's d = 0.56). Exploratory analysis shows that Vets Prevail may be effective regardless of combat trauma exposure, gender, and ethnic minority status. Vets Prevail circumvents many barriers to care and effectively addresses the dire mental health needs of veterans. (c) 2015 APA, all rights reserved).

Autonomy and the Moral Authority of Advance Directives.

PubMed

Vogelstein, Eric

2016-10-01

Although advance directives are widely believed to be a key way to safeguard the autonomy of incompetent medical patients, significant questions exist about their moral authority. The main philosophical concern involves cases in which an incompetent patient no longer possesses the desires on which her advance directive was based (e.g., in cases of severe dementia). The question is, does that entail that prior expressions of medical choices are no longer morally binding? I believe that the answer is "yes." I argue that a patient's autonomy is not respected by honoring the desires she used to have but no longer does. I also consider and reject the view that honoring an advance directive that reflects the patient's previous values must be in that patient's best interests. If that is correct, then advance directives in the kind of case at issue are not morally binding. © The Author 2016.

Determinants of longer job tenure among home care aides: what makes some stay on the job while others leave?

PubMed

Butler, Sandra S; Brennan-Ing, Mark; Wardamasky, Sara; Ashley, Alison

2014-03-01

An inadequate supply of direct care workers and a high turnover rate in the workforce has resulted in a "care gap" in our long-term care system. As people are increasingly choosing community-based care, retention of home care workers is particularly important. The mixed-method study described herein explored determinants of longer job tenure for home care aides (n = 261). Study participants were followed for 18 months, completing two mail surveys and one telephone interview each. Predictors of longer job tenure included older age, living rurally, lower physical function, higher wages, a greater sense of autonomy on the job, and less frequent feelings of personal accomplishment. Thematic analysis of telephone interviews revealed long-term stayers to be less concerned about low wages and inconsistent hours than those who left their jobs within a year; both groups of workers reported high levels of job satisfaction. Policy implications of study findings are discussed.

Doctor-patient communication in a Southeast Asian setting: the conflict between ideal and reality.

PubMed

Claramita, Mora; Utarini, Adi; Soebono, Hardyanto; Van Dalen, Jan; Van der Vleuten, Cees

2011-03-01

Doctor-patient communication has been extensively studied in non-Western contexts and in relation to patients' cultural and education backgrounds. This study explores the perceived ideal communication style for doctor-patient consultations and the reality of actual practice in a Southeast Asian context. We conducted the study in a teaching hospital in Indonesia, using a qualitative and a quantitative design. In-depth interviews were conducted with ten internal medicine specialists, ten internal medicine residents, 16 patients in two groups based on education level and ten most senior medical students. The contributions of doctors and patients to the communication during consultations were observed and rated quantitatively by thirty internal medicine residents, 393 patients with different educational backgrounds and ten senior medical students. The 'informed and shared decision making' is the central observation in this quantitative study. The results of the interviews showed that Southeast Asian stakeholders are in favor of a partnership style of communication and revealed barriers to achieving this: doctors and patients are not prepared for a participatory style and high patient load due to an inefficient health care system does not allow sufficient time for this type of communication. The results of the quantitative study showed a sharp contrast between observed and ideal communication styles. A paternalistic style seems to prevail, irrespective of patients' educational background. We found a sharp conflict between ideal and reality concerning doctor-patient communication in a Southeast Asian context. Further studies should examine ways to change the prevailing communication style in the desired direction.

Does it get easier to use an EHR? Report from an urban regional extension center.

Ryan, Mandy Smith; Shih, Sarah C; Winther, Chloe H; Wang, Jason J

2014-10-01

Little is known about whether more experience with an electronic health record (EHR) makes it easier for providers to meaningfully use EHRs. To assess whether the length of time that small practice providers have been using the EHR is associated with greater ease in performing meaningful use-related tasks and fewer EHR-related concerns. We administered a web-based survey to 400 small practice providers in medically underserved communities in New York City participating in an EHR implementation and technical assistance project. We used logistic regression to estimate the association between the length of time a provider had been using the EHR (i.e., "live") and the ease of performing meaningful use-related tasks and EHR-related concerns, controlling for provider and practice characteristics. Compared to providers who had been live 6 to 12 months, providers who had been live 2 years or longer had 2.02 times greater odds of reporting it was easy to e-prescribe new prescriptions (p < 0.05), 2.12 times greater odds of reporting it was easy to e-prescribe renewal prescriptions (p < 0.05), 2.02 times greater odds of reporting that quality measures were easy to report (p < 0.05), 2.64 times greater odds of reporting it was easy to incorporate lab results as structured data (p < 0.001), and 2.00 times greater odds of reporting it was easy to generate patient lists by condition (p < 0.05). Providers who had been live 2 years or longer had 0.40 times lower odds of reporting financial costs were a concern (p < 0.001), 0.46 times lower odds of reporting that productivity loss was a concern (p < 0.05), 0.54 times lower odds of reporting that EHR unreliability was a concern (p < 0.05), and 0.50 times lower odds of reporting that privacy/security was a concern (p < 0.05). Providers can successfully adjust to the EHR and over time are better able to meaningfully use the EHR.

The behavioral, psychological, and sociological aspects of space travel, particularly with emphasis on longer duration missions, are discussed along with the biomedical aspects of space flight. These factors may strongly interact with the various psycho-social factors and as such they stand as an immensely important area of concern in and of themselves. A foundation for understanding weightlessness related medical problems through a discussion of the history of symptoms reported specific details on the major areas of concern and approaches to their investigation are presented. Also, discussion is given to the possibility of various countermeasures. Some indication of the effects of various biomedical changes in performance are also covered.

Your friends know how long you will live: a 75-year study of peer-rated personality traits.

PubMed

Jackson, Joshua J; Connolly, James J; Garrison, S Mason; Leveille, Madeleine M; Connolly, Seamus L

2015-03-01

Although self-rated personality traits predict mortality risk, no study has examined whether one's friends can perceive personality characteristics that predict one's mortality risk. Moreover, it is unclear whether observers' reports (compared with self-reports) provide better or unique information concerning the personal characteristics that result in longer and healthier lives. To test whether friends' reports of personality predict mortality risk, we used data from a 75-year longitudinal study (the Kelly/Connolly Longitudinal Study on Personality and Aging). In that study, 600 participants were observed beginning in 1935 through 1938, when they were in their mid-20s, and continuing through 2013. Male participants seen by their friends as more conscientious and open lived longer, whereas friend-rated emotional stability and agreeableness were protective for women. Friends' ratings were better predictors of longevity than were self-reports of personality, in part because friends' ratings could be aggregated to provide a more reliable assessment. Our findings demonstrate the utility of observers' reports in the study of health and provide insights concerning the pathways by which personality traits influence health. © The Author(s) 2015.

Hymen protection and the sexual practices, perceptions, and attitudes of female university students from Lebanon.

El Kak, Faysal; El Salibi, Noura; Yasmine, Rola; Ghandour, Lilian

2017-11-01

To investigate associations between hymen protection and women's alternative sexual practices, perceptions, and attitudes. A cross-sectional online survey was administered among university students (aged 18-30 years) in Lebanon between April 30 and August 31, 2012. The present analysis focused on female students who had engaged in oral/anal sex. Among 416 included women, 163 (39.3%) reported anal/oral sex to protect their hymen. Women ever concerned with hymen protection were less likely to be non-Lebanese and not religious/spiritual, but more likely to report unwanted sexual activities, a relationship in which they felt things were moving too fast physically, and to feel guilty about sexual feelings (all P<0.01). They were two-to-three times more likely to agree that it is harder to refuse sex after the first time and that oral sex is not as big of a deal as sexual intercourse (both P<0.001). Concerned women who later engaged in vaginal sex (n=75) were less religious and more accepting of premarital sex than were those who continued to protect their hymen (n=88; all P<0.005). Women concerned about hymen-breaking engage in alternative sexual practices, yet experience pressure, guilt, worry, and indecisiveness regarding their sex-related decisions. The navigation of sexual decisions is a more vulnerable process for these women because of prevailing patriarchal values and discriminating gender norms in Lebanon. © 2017 International Federation of Gynecology and Obstetrics.

The dead donor rule and the concept of death: severing the ties that bind them.

PubMed

Koppelman, Elysa R

2003-01-01

One goal of the transplant community is to seek ways to increase the number of people who are willing and able to donate organs. People in states between life and death are often medically excellent candidates for donating organs. Yet public policy surrounding organ procurement is a delicate matter. While there is the utilitarian goal of increasing organ supply, there is also the deontologic concern about respect for persons. Public policy must properly mediate between these two concerns. Currently the dead donor (dd) rule is appealed to as an attempt at such mediation. I argue that given the lack of consensus on a definition of death, the dd rule is no longer successful at mediating utilitarian and deontologic concerns. I suggest instead that focusing on a particular person's history can be successful.

Building public trust in uses of Health Insurance Portability and Accountability Act de-identified data.

PubMed

McGraw, Deven

2013-01-01

The aim of this paper is to summarize concerns with the de-identification standard and methodologies established under the Health Insurance Portability and Accountability Act (HIPAA) regulations, and report some potential policies to address those concerns that were discussed at a recent workshop attended by industry, consumer, academic and research stakeholders. The target audience includes researchers, industry stakeholders, policy makers and consumer advocates concerned about preserving the ability to use HIPAA de-identified data for a range of important secondary uses. HIPAA sets forth methodologies for de-identifying health data; once such data are de-identified, they are no longer subject to HIPAA regulations and can be used for any purpose. Concerns have been raised about the sufficiency of HIPAA de-identification methodologies, the lack of legal accountability for unauthorized re-identification of de-identified data, and insufficient public transparency about de-identified data uses. Although there is little published evidence of the re-identification of properly de-identified datasets, such concerns appear to be increasing. This article discusses policy proposals intended to address de-identification concerns while maintaining de-identification as an effective tool for protecting privacy and preserving the ability to leverage health data for secondary purposes.

Opportunities and challenges of nanotechnology in the green economy.

Iavicoli, Ivo; Leso, Veruscka; Ricciardi, Walter; Hodson, Laura L; Hoover, Mark D

2014-10-07

In a world of finite resources and ecosystem capacity, the prevailing model of economic growth, founded on ever-increasing consumption of resources and emission pollutants, cannot be sustained any longer. In this context, the "green economy" concept has offered the opportunity to change the way that society manages the interaction of the environmental and economic domains. To enable society to build and sustain a green economy, the associated concept of "green nanotechnology" aims to exploit nano-innovations in materials science and engineering to generate products and processes that are energy efficient as well as economically and environmentally sustainable. These applications are expected to impact a large range of economic sectors, such as energy production and storage, clean up-technologies, as well as construction and related infrastructure industries. These solutions may offer the opportunities to reduce pressure on raw materials trading on renewable energy, to improve power delivery systems to be more reliable, efficient and safe as well as to use unconventional water sources or nano-enabled construction products therefore providing better ecosystem and livelihood conditions.However, the benefits of incorporating nanomaterials in green products and processes may bring challenges with them for environmental, health and safety risks, ethical and social issues, as well as uncertainty concerning market and consumer acceptance. Therefore, our aim is to examine the relationships among guiding principles for a green economy and opportunities for introducing nano-applications in this field as well as to critically analyze their practical challenges, especially related to the impact that they may have on the health and safety of workers involved in this innovative sector. These are principally due to the not fully known nanomaterial hazardous properties, as well as to the difficulties in characterizing exposure and defining emerging risks for the workforce. Interestingly, this review proposes action strategies for the assessment, management and communication of risks aimed to precautionary adopt preventive measures including formation and training of employees, collective and personal protective equipment, health surveillance programs to protect the health and safety of nano-workers. It finally underlines the importance that occupational health considerations will have on achieving an effectively sustainable development of nanotechnology.

A carbon dioxide stripping model for mammalian cell culture in manufacturing scale bioreactors.

Xing, Zizhuo; Lewis, Amanda M; Borys, Michael C; Li, Zheng Jian

2017-06-01

Control of carbon dioxide within the optimum range is important in mammalian bioprocesses at the manufacturing scale in order to ensure robust cell growth, high protein yields, and consistent quality attributes. The majority of bioprocess development work is done in laboratory bioreactors, in which carbon dioxide levels are more easily controlled. Some challenges in carbon dioxide control can present themselves when cell culture processes are scaled up, because carbon dioxide accumulation is a common feature due to longer gas-residence time of mammalian cell culture in large scale bioreactors. A carbon dioxide stripping model can be used to better understand and optimize parameters that are critical to cell culture processes at the manufacturing scale. The prevailing carbon dioxide stripping models in literature depend on mass transfer coefficients and were applicable to cell culture processes with low cell density or at stationary/cell death phase. However, it was reported that gas bubbles are saturated with carbon dioxide before leaving the culture, which makes carbon dioxide stripping no longer depend on a mass transfer coefficient in the new generation cell culture processes characterized by longer exponential growth phase, higher peak viable cell densities, and higher specific production rate. Here, we present a new carbon dioxide stripping model for manufacturing scale bioreactors, which is independent of carbon dioxide mass transfer coefficient, but takes into account the gas-residence time and gas CO 2 saturation time. The model was verified by CHO cell culture processes with different peak viable cell densities (7 to 12 × 10 6  cells mL -1 ) for two products in 5,000-L and 25,000-L bioreactors. The model was also applied to a next generation cell culture process to optimize cell culture conditions and reduce carbon dioxide levels at manufacturing scale. The model provides a useful tool to understand and better control cell culture carbon dioxide profiles for process development, scale up, and characterization. Biotechnol.

Projection Exposure with Variable Axis Immersion Lenses: A High-Throughput Electron Beam Approach to “Suboptical” Lithography

NASA Astrophysics Data System (ADS)

Pfeiffer, Hans

1995-12-01

IBM's high-throughput e-beam stepper approach PRojection Exposure with Variable Axis Immersion Lenses (PREVAIL) is reviewed. The PREVAIL concept combines technology building blocks of our probe-forming EL-3 and EL-4 systems with the exposure efficiency of pattern projection. The technology represents an extension of the shaped-beam approach toward massively parallel pixel projection. As demonstrated, the use of variable-axis lenses can provide large field coverage through reduction of off-axis aberrations which limit the performance of conventional projection systems. Subfield pattern sections containing 107 or more pixels can be electronically selected (mask plane), projected and positioned (wafer plane) at high speed. To generate the entire chip pattern subfields must be stitched together sequentially in a combination of electronic and mechanical positioning of mask and wafer. The PREVAIL technology promises throughput levels competitive with those of optical steppers at superior resolution. The PREVAIL project is being pursued to demonstrate the viability of the technology and to develop an e-beam alternative to “suboptical” lithography.

[Paradigmatic shifts in clinical practice in the the last generation].

PubMed

Benbassat, J

1996-05-01

Physicians have always used theoretical models (paradigms) to interpret clinical reality, and have changed the prevailing model only when it could no longer satisfy clinical needs. The purpose of this essay is to review some of the paradigmatic changes in clinical reasoning that have occurred since my undergraduate medial education. My training in the 50's was along the bio-medical model that reduced all diseases to structural or biochemical dysfunctions. Within this framework, causes were perceived as leading inevitably rather than probabilistically to their consequences, and chance and ambiguity had a very small role in explication of pathophysiologic mechanisms and in diagnostic reasoning. The doctor-patient relationship was paternalistic and the orientation to extending survival rejected notions of quality of life and involved parsimonious utilization of health care resources. Today however, clinical reasoning has shifted from deductive and deterministic to inductive (evidence-based) and probabilistic. Disease is believed to result from multiple factors rather than from single causes, and there is increasing acceptance of psycho-social factors of disease. Awareness of the confounding effects of false-positive and false-negative tests has changed the attitude to diagnostic evaluation. Terms, such as risk indicators of disease, predictive value of tests and risk-benefit ratio are increasingly used in discussing clinical decisions. We respect the patient's autonomy more than we did in the past, and consider his/her preferences and quality of life in clinical decision-making. Fair distribution of medical resources is considered as an ethical principle. Finally, clinical guidelines are no longer viewed as counter-intuitive, but rather as effective means to reduce the disturbingly high rates of medical error.

Long-term outcome of major depressive disorder in psychiatric patients is variable.

2008-02-01

The prevailing view of outcome of major depressive disorder (MDD), based on mostly inpatient cohorts sampled from tertiary centers, emphasizes chronicity and frequent recurrences. We investigated the long-term outcome of a regionally representative psychiatric MDD cohort comprising mainly outpatients. The Vantaa Depression Study included 163 patients with DSM-IV MDD (71.5% of those eligible) diagnosed using structured and semistructured interviews and followed up at 6 months, 18 months, and 5 years with a life chart between February 1, 1997, and April 30, 2004. The effects of comorbid disorders and other predictors on outcome were comprehensively investigated. Over the 5-year follow-up, 98.8% of patients achieved a symptom state below major depressive episode (MDE) criteria, and 88.4% reached full remission, with the median time to full remission being 11.0 months. Nearly one third (29.3%) had no recurrences, whereas 30.0% experienced 1, 12.9% experienced 2, and 27.9% experienced 3 or more recurrences. Preceding dysthymic disorder (p = .028), cluster C personality disorder (p = .041), and longer MDE duration prior to entry (p = .011) were the most significant predictors of longer time in achieving full remission. Severity of MDD and comorbidity, especially social phobia, predicted probability of, shorter time to, and number of recurrences. Previous literature on mostly inpatient MDD may have, by generalizing from patients with the most severe psychopathology, overemphasized chronicity of MDD. The long-term outcome of MDD in psychiatric care is variable, with about one tenth of patients having poor, one third having intermediate, and one half having favorable outcomes. In addition to known predictors, cluster C personality disorders and social phobia warrant further attention as predictors of MDD outcome among outpatients.

Determinants of Malnutrition and Post-operative Complications in Hospitalized Surgical Patients

PubMed Central

de Aquino, José Luiz Braga

2014-01-01

ABSTRACT The study aimed to determine the nutritional status (NS) of hospitalized surgical patients and investigate a possible association between NS and type of disease, type of surgery and post-operative complications. The gender, age, disease, surgery, complications, length of hospital stay, number of medications, laboratory test results, and energy intake of 388 hospitalized surgical patients were recorded. NS was determined by classical anthropometry. The inclusion criteria were: nutritional status assessment done within the first 24 hours of admission, age ≥20 years, and complete medical history. Univariate and multiple Cox's regression analyses were employed to determine which variables were possible risk factors of malnutrition and complications. Malnutrition was more common in males (p=0.017), individuals aged 70 to 79 years (p=0.000), and individuals with neoplasms and digestive tract diseases (p=0.000). Malnourished individuals had longer hospital stays (p=0.013) and required more medications (p=0.001). The risk of malnutrition was associated with age and disease. Individuals aged 70 years or more had a two-fold increased risk of malnutrition (p=0.014; RR=2.207; 95% CI 1.169-4.165); those with neoplasms (p=0.008; RR=14.950; 95% CI 2.011-111.151) and those having digestive tract diseases (p=0.009; RR=14.826; 95% CI 1.939-113.362) had a 14-fold increased risk of malnutrition. Complications prevailed in older individuals (p=0.016), individuals with longer hospital stays (p=0.007), and individuals who died (p=0.002). The risk of complications was associated with age and BMI. In the present study, the risk of malnutrition was associated with age and type of disease; old age and low BMI may increase complications.

[Health and gender relations: a reflection on the challenges for the implementation of public policies for health care for indigenous women].

PubMed

Ferreira, Luciane Ouriques

2013-04-01

This article presents some contrasts that exist between the discourses of public policies concerning women's health care, especially with respect to indigenous women, and the ethnological discourse which emphasizes the specificity of gender relations within indigenous societies. We worked on the assumption that the development of these public policies as well as the organization of health care services offered, which in fact are necessary, have a transforming effect on prevailing gender relations within Amerindian Societies. On the one hand, gender relations between indigenous people are associated with the domains of kinship and corporeality. On the other hand, the process of creating public policies, by means of biomedical intervention and the medicalization of the female body, constitutes a powerful tool for body modeling and the construction of subjectivities contributing to making women worthy of citizenship. The female gender is under discussion and its content is being negotiated.

The changing pattern of higher education in England and Wales — The end of an era?

NASA Astrophysics Data System (ADS)

Watson, Keith

1989-09-01

During the past twenty years great changes have taken place in British higher education. During the 1980s these changes have been even more noticeable, so that by the middle of the 1990s the pattern and the ethos of British higher education will be very different from that prevailing in the 1970s. Not only have there been structural changes but there have also been concerns about autonomy and freedom, accountability and appraisal in the face of government demands for improved management efficiency, restrictions on tenure and alternative forms of finance. This paper analyses these changes in universities, polytechnics and teacher education colleges and traces the growing intervention on the part of government. It also seeks to draw out implications for other education systems facing the same pressures. A glossary of abbreviations and acronyms appears on p. 301.

Plastic litter in sediments from the coasts of south Tuscany (Tyrrhenian Sea).

2017-06-15

This study estimated the total loads of plastic litter (macro-meso- and micro-plastics) in sediments from a wide stretch of marine and coastal environment of Tyrrhenian Sea. The prevailing category of debris was microplastic. The results obtained, in terms of average amount of microplastic per kilogram of dry sediment, are in agreement with data reported by various Authors internationally. The study area resulted to be uniform for plastic items levels. Particularly evident was the influence of a flood, occurred in November 2012 in Talamone, on sediments collected at the harbour of this locality: in this area, a difference in levels and quality of plastic debris, attributable to periods before and after the flood, was observed in sediments. In addition to focusing on the effect of this phenomenon, this study gives an important overview, for what concerns the presence of plastic litter, of a significant naturalistic area.

Probabilistic estimation of long-term volcanic hazard under evolving tectonic conditions in a 1 Ma timeframe

NASA Astrophysics Data System (ADS)

Jaquet, O.; Lantuéjoul, C.; Goto, J.

2017-10-01

Risk assessments in relation to the siting of potential deep geological repositories for radioactive wastes demand the estimation of long-term tectonic hazards such as volcanicity and rock deformation. Owing to their tectonic situation, such evaluations concern many industrial regions around the world. For sites near volcanically active regions, a prevailing source of uncertainty is related to volcanic hazard. For specific situations, in particular in relation to geological repository siting, the requirements for the assessment of volcanic and tectonic hazards have to be expanded to 1 million years. At such time scales, tectonic changes are likely to influence volcanic hazard and therefore a particular stochastic model needs to be developed for the estimation of volcanic hazard. The concepts and theoretical basis of the proposed model are given and a methodological illustration is provided using data from the Tohoku region of Japan.

Elucidating unconscious processing with instrumental hypnosis

PubMed Central

Landry, Mathieu; Appourchaux, Krystèle; Raz, Amir

2014-01-01

Most researchers leverage bottom-up suppression to unlock the underlying mechanisms of unconscious processing. However, a top-down approach – for example via hypnotic suggestion – paves the road to experimental innovation and complementary data that afford new scientific insights concerning attention and the unconscious. Drawing from a reliable taxonomy that differentiates subliminal and preconscious processing, we outline how an experimental trajectory that champions top-down suppression techniques, such as those practiced in hypnosis, is uniquely poised to further contextualize and refine our scientific understanding of unconscious processing. Examining subliminal and preconscious methods, we demonstrate how instrumental hypnosis provides a reliable adjunct that supplements contemporary approaches. Specifically, we provide an integrative synthesis of the advantages and shortcomings that accompany a top-down approach to probe the unconscious mind. Our account provides a larger framework for complementing the results from core studies involving prevailing subliminal and preconscious techniques. PMID:25120504

Skin interaction with absorbent hygiene products.

PubMed

Runeman, Bo

2008-01-01

Skin problems due to the use of absorbent hygiene products, such as diapers, incontinence pads, and feminine sanitary articles, are mostly due to climate or chafing discomfort. If these conditions are allowed to prevail, these may develop into an irritant contact dermatitis and eventually superficial skin infections. Skin humidity and aging skin are among the most significant predisposing and aggravating factors for dermatitis development. Improved product design features are believed to explain the decline in observed diaper dermatitis among infants. Where adult incontinence-related skin problems are concerned, it is very important to apply a holistic perspective to understand the influences due to the individual's incontinence level and skin condition, as well as the hygiene and skin care measures provided. Individuals with frail, sensitive skin or with skin diseases may preferably have to use high-quality products, equipped with superabsorbent polymers and water vapor-permeable back sheets, to minimize the risk of skin complications.

Electromagnetic resonances of plasma column between two metallic plates

NASA Astrophysics Data System (ADS)

Dvinin, Sergey; Dovzhenko, Vitaly; Sinkevich, Oleg

2015-09-01

It is known that there are two types of electrodynamic resonances of bounded supercritical plasma, placed between the two metal planes are possible. The first type is associated with the excitation of surface waves propagating along the lateral surface. The second one is caused by standing surface waves in the sheath at plasma-metal boundary. This work is concerned with theoretical study of the resonance properties of plasma slab in cases where both effects can be observed together. Resonance densities and frequencies are calculated. Solution of Maxwell's equations is demonstrated that directions of energy flows in first and second cases are opposite. Energy transfer to lateral surface waves is prevailing, if the field frequency is higher than the frequency, corresponding to the geometric plasma-sheath resonance. Amplitude of waves at plasma metal boundary becomes greater in opposite case. Discharge properties in both cases are calculated including joint excitation.

Could Revision of the Embryology Influence Our Cesarean Delivery Technique: Towards an Optimized Cesarean Delivery for Universal Use

PubMed Central

Stark, Michael; Mynbaev, Ospan; Vassilevski, Yuri; Rozenberg, Patrick

2016-01-01

Until today, there is no standardized Cesarean Section method and many variations exist. The main variations concern the type of abdominal incision, usage of abdominal packs, suturing the uterus in one or two layers, and suturing the peritoneal layers or leaving them open. One of the questions is the optimal location of opening the uterus. Recently, omission of the bladder flap was recommended. The anatomy and histology as results from the embryological knowledge might help to solve this question. The working thesis is that the higher the incision is done, the more damage to muscle tissue can take place contrary to incision in the lower segment, where fibrous tissue prevails. In this perspective, a call for participation in a two-armed prospective study is included, which could result in an optimal, evidence-based Cesarean Section for universal use. PMID:28078171

Putting houses in place: rebuilding communities in post-tsunami Sri Lanka.

PubMed

Ruwanpura, Kanchana N

2009-07-01

This paper interrogates the social and political geographies of resettlement and reconstruction of temporary and permanent shelters, which are fundamental to rebuilding tsunami-affected communities. War and ethnic cleavages are an endemic feature of Sri Lanka's social polity, and uneven development processes in the country are clearly visible. This paper draws attention to these spaces of inequality by drawing on in-depth interviews and participant observation carried out in Eastern and Southern Sri Lanka. It argues that communities' concerns and anxieties regarding displacement and resettlement have tended to be articulated against prevailing fault lines of war and inequality. This is the backdrop against which communities negotiated the recovery process. My fieldwork shows that it is critical to understand that disaster and development relief are ingrained within context specificities. Relief efforts therefore need to recognise that the process of 'putting houses in place' should be embedded within local social relations.

Feyerabend on politics, education, and scientific culture.

PubMed

Kidd, Ian James

2016-06-01

The purpose of this paper is to offer a sympathetic reconstruction of the political thought of Paul Feyerabend. Using a critical discussion of the idea of the 'free society' it is suggested that his political thought is best understood in terms of three thematic concerns-liberation, hegemony, and the authority of science-and that the political significance of those claims become clear when they are considered in the context of his educational views. It emerges that Feyerabend is best understood as calling for the grounding of cognitive and cultural authorities-like the sciences-in informed deliberation, rather than the uncritical embrace of prevailing convictions. It therefore emerges that a free society is best understood as one of epistemically responsible citizenship rather than epistemically anarchistic relativism of the 'anything goes' sort-a striking anticipation of current debates about philosophy of science in society.

A historical synopsis of farm animal disease and public policy in twentieth century Britain

PubMed Central

Woods, Abigail

2011-01-01

The diseases suffered by British livestock, and the ways in which they were perceived and managed by farmers, vets and the state, changed considerably over the course of the twentieth century. This paper documents and analyses these changes in relation to the development of public policy. It reveals that scientific knowledge and disease demographics cannot by themselves explain the shifting boundaries of state responsibility for animal health, the diseases targeted and the preferred modes of intervention. Policies were shaped also by concerns over food security and the public's health, the state of the national and livestock economy, the interests and expertise of the veterinary profession, and prevailing agricultural policy. This paper demonstrates how, by precipitating changes to farming and trading practices, public policy could sometimes actually undermine farm animal health. Animal disease can therefore be viewed both as a stimulus to, and a consequence of, twentieth century public policy. PMID:21624915

Poverty and experiences of social devaluation: a qualitative interview study of 25 long-standing recipients of social security payments.

PubMed

Underlid, Kjell

2005-07-01

The purpose of this study is to explore experiences of social devaluation among people living in poverty. Twenty-five long-standing recipients of social security payments living in a city in Norway were interviewed. Most felt that people in their environment held low opinions of them regarding issues related to personality and moral integrity. Several factors play a role in the formation of such beliefs or assumptions: (a) impressions of prevailing views of the social category "the poor" and observations concerning devaluation of that category; (b) knowledge others are assumed to possess of the respondents' financial predicament; (c) perception of own social situation; (d) undesired behavior that signals low social status and low esteem; (e) actions by others that signal devaluation. Social devaluation is also experienced at the affective level: the sense of shame and guilt is widespread.

Substance use disorders in schizophrenia: review, integration, and a proposed model.

PubMed

Blanchard, J J; Brown, S A; Horan, W P; Sherwood, A R

2000-03-01

Substance use disorders occur in approximately 40 to 50% of individuals with schizophrenia. Clinically, substance use disorders are associated with a variety of negative outcomes in schizophrenia, including incarceration, homelessness, violence, and suicide. An understanding of the reasons for such high rates of substance use disorders may yield insights into the treatment of this comorbidity in schizophrenia. This review summarizes methodological and conceptual issues concerning the study of substance use disorders in schizophrenia and provides a review of the prevalence of this co-occurrence. Prevailing theories regarding the co-occurrence of schizophrenia and substance use disorders are reviewed. Little empirical support is found for models suggesting that schizophrenic symptoms lead to substance use (self-medication), that substance use leads to schizophrenia, or that there is a genetic relationship between schizophrenia and substance use. An integrative affect-regulation model incorporating individual differences in traits and responses to stress is proposed for future study.

Annual banned-substance review: Analytical approaches in human sports drug testing.

Thevis, Mario; Kuuranne, Tiia; Geyer, Hans

2018-01-01

Several high-profile revelations concerning anti-doping rule violations over the past 12 months have outlined the importance of tackling prevailing challenges and reducing the limitations of the current anti-doping system. At this time, the necessity to enhance, expand, and improve analytical test methods in response to the substances outlined in the World Anti-Doping Agency's (WADA) Prohibited List represents an increasingly crucial task for modern sports drug-testing programs. The ability to improve analytical testing methods often relies on the expedient application of novel information regarding superior target analytes for sports drug-testing assays, drug elimination profiles, alternative test matrices, together with recent advances in instrumental developments. This annual banned-substance review evaluates literature published between October 2016 and September 2017 offering an in-depth evaluation of developments in these arenas and their potential application to substances reported in WADA's 2017 Prohibited List.

Knowledge levels of food handlers in Portuguese school canteens and their self-reported behaviour towards food safety.

PubMed

Santos, Maria-José; Nogueira, José Rocha; Patarata, Luis; Mayan, Olga

2008-12-01

Food safety levels in school food services are an important concern, given that any incident can affect a high number of students. The purpose of this research was to evaluate food handlers' knowledge and self-reported behaviour as regards the safe handling of food in school canteens. The study was conducted in 32 school canteens and included 124 participants. Food handlers displayed a reasonable level of knowledge, particularly regarding personal hygiene and cross-contamination, but fared worse in other areas. The level of knowledge displayed was influenced by age, motivation and training. A high correctness in handlers' self-reported behaviour towards food safety was observed, with a negative trend appearing when workload was increased. Our assessment of prevailing knowledge levels indicates that food professionals need to be made significantly more aware of the importance their actions can have on children's health.

Legal issues in the development and use of clinical practice guidelines.

PubMed

Gevers, S

2001-01-01

Over the last ten years, the development and dissemination of practice guidelines has increased at a rapid pace. From a legal point of view, it should always be made clear whether a guideline has been developed to improve the quality of care and is based on medical evidence and professional experience, or whether other concerns and considerations (organisational, financial) did prevail. Guidelines should not simply be imposed on health professionals; that would result in a standardisation of care that does no justice to individual patient needs and preferences. Patients have the right to be informed about reasonable and realistic treatment alternatives, even if they are not included in the guideline. Using cost effectiveness analysis in guideline development can help to reduce care of dubious effectiveness. But if cost considerations are used as a reason to limit effective medical care, the guidelines in question need political legitimation.

The politics of paranoia.

PubMed

Belkin, Aaron

2013-01-01

For almost 20 years, gay rights advocates and defenders of military anti-gay discrimination engaged in a phony debate about whether allowing open service would undermine unit cohesion. To be sure, a preponderance of evidence showed that open service would not undermine cohesion, and the repeal of don't ask, don't tell (DADT) required advocates to prevail on that point in the court of public opinion. But concerns about cohesion were never the basis of opposition to open service. Rather, opposition was a modern incarnation of the politics of paranoia, a dangerous tradition in American history. Acknowledging that DADT had nothing to do with cohesion and that military leaders allowed the armed forces to be implicated in the politics of paranoia could facilitate disabling paranoia as the basis for other political projects such as anti-immigrant xenophobia. For a video on DADT and paranoia, search for "Donnelly Belkin DADT" on YoutTube.

'You Wouldn't have Your Granny Using Them': Drawing Boundaries Between Acceptable and Unacceptable Applications of Civil Drones.

PubMed

Boucher, Philip

2016-10-01

Some industry and policy actors are concerned about public opposition to civil drones, in particular because of their association with military drones. However, very little is understood about public reactions to the technology. Strategies to 'manage public acceptance' have so far relied upon several untested assumptions. We conducted public engagement activities to explore citizens' visions of civil drones. Several insights counteracted the prevailing assumptions. Rejecting the notion of blanket support for or opposition to civil drones, we found that citizens make nuanced decisions about the acceptability of civil drones depending upon the purpose of the flight and the actors involved. The results are positioned in support for calls to strengthen the role of citizens in civil drone development and, in particular, to shift away from the current focus on citizens' acceptance of civil drone development towards the development of civil drones that are acceptable to citizens.

The politics of protection: aid, human rights discourse, and power relations in Kyaka II settlement, Uganda.

PubMed

Clark-Kazak, Christina R

2010-01-01

This paper explores the conceptualisation and application of 'protection' by the United Nations High Commissioner (UNHCR), Ugandan government, and Congolese refugees in Kyaka II refugee settlement, Uganda. Analysing the origins and consequences of a demonstration against school fees, and drawing on other ethnographic data, it explores how different interpretations of this incident reflect different conceptions of, and approaches to, protection. Ugandan government officials viewed the demonstration as a security incident; Congolese and Ugandan adults responded with increased monitoring and 'sheltering' of children and young people; students justified the demonstration as a legitimate manifestation of their rights; while UNHCR promoted assistance and resettlement. The paper argues that prevailing protection responses, including 'sensitisation', sheltering, and resettlement, are de-contextualised from daily realities and fail to address the underlying power relations that undermine protection. It concludes with recommendations on how international refugee agencies can reorient assistance to address protection concerns in refugee contexts.

Duration of extinction trials as a determinant of instrumental extinction in terrestrial toads (Rhinella arenarum).

PubMed

Puddington, Martín M; Papini, Mauricio R; Muzio, Rubén N

2018-01-01

Instrumental learning guides behavior toward resources. When such resources are no longer available, approach to previously reinforced locations is reduced, a process called extinction. The present experiments are concerned with factors affecting the extinction of acquired behaviors in toads. In previous experiments, total reward magnitude in acquisition and duration of extinction trials were confounded. The present experiments were designed to test the effects of these factors in factorial designs. Experiment 1 varied reward magnitude (900, 300, or 100 s of water access per trial) and amount of acquisition training (5 or 15 daily trials). With total amount of water access equated in acquisition, extinction with large rewards was faster (longer latencies in 900/5 than 300/15), but with total amount of training equated, extinction with small rewards was faster (longer latencies in 100/15 than 300/15). Experiment 2 varied reward magnitude (1200 or 120 s of water access per trial) while holding constant the number of acquisition trials (5 daily trials) and the duration of extinction trials (300 s). Extinction performance was lower with small, rather than large reward magnitude (longer latencies in 120/300 than in 1200/300). Thus, instrumental extinction depends upon the amount of time toads are exposed to the empty goal compartment during extinction trials.

Data compared to WHO child grows standard percentage-charts, and to percentile diagram made for georgian children and adolescents in 2001-2003. Concerning the height indexes stunting was noticed among the village resident girls at the age 9-14 (8,9%) and 9-11 year old boys (3,8%) and it also prevails among girls that require further researches to reveal reasons. Also the amount of law height index among girls and boys is high in the cities as well as villages although it prevails in the villages, mostly among boys (30, 8%). Comparing with village residents high height index prevails among the city resident boys (18,7%) and among girls (11, 9%), and higher than 97 percentile indexes is revealed among 4,9% of boys living in the city. Mass deficiency was reveled among the city girls 2,4 % and the village resident girls 5,1%; accordingly it is prevailed among girls living in the villages. Mass deficiency among the boys was only revealed among the city residents and it was 3,9 %. According to our data, decrease of the body mass average index is fixed among girls but among the boys it increase. and among 2,4% of girls. So village resident girls are shorter and thinner, but boys are short and overweight, comparing with the city residents. Research based on questionnaires showed that city resident school children food ration, whose social-economic condition is better, is rich with proteins, when majority of village residents food ration lack proteins and mostly consist of those products which are rich of carbohydrates. According to surveys low physical activity was revealed among city as well as village resident school children, especially in boys. Average height indexes based on our researches have been compared to percentile diagrams for children and adolescents of Georgia , based on researches held in 2001-2003. The average height indexes of the students born in 2000 and following years (including from 6 - 13 years) are located between the percentage indexes 50-90 established for Georgian children, but at the ages 14-18 between 10-50 which indicates to the tendency of increasing height of schoolchildren in the city and villages During the last years, tendency in the increasing of height is fixed in India and Sri Lanka.

Nanoparticle Toxicity Mechanisms: Oxidative Stress and Inflammation

NASA Astrophysics Data System (ADS)

L'Azou, Béatrice; Marano, Francelyne

Toxicology plays a key role in understanding the potentially harmful biological effects of nanoparticles, since epidemiological studies are still difficult to implement given the lack of data concerning exposure. For this reason, in 2005, Günter Oberdörster coined the term `nanotoxicology' to specify the emerging discipline that dealt with ultrafine particles (UFP). It involves in vivo or in vitro studies under controlled conditions to establish the dose-response relationship, so difficult to expose by epidemiological studies. It also aims to determine the thresholds below which biological effects are no longer observed. It is concerned with the role played by properties specific to nanoparticles in the biological response: size, surface reactivity, chemical composition, solubility, etc.

PREVAIL was a phase III multinational, double-blind, placebo-controlled trial that enrolled chemotherapy-naïve men with metastatic castration-resistant prostate cancer (mCRPC), which showed remarkable improvement in co-primary endpoints with an overall 81% reduction in the risk of radiographic progression, as well as 29% reduction in the risk of death in favor of the enzalutamide arm over placebo. All secondary endpoints including time to subsequent chemotherapy initiation and prostate specific antigen (PSA) progression were in favor of the enzalutamide arm. The results of PREVAIL shows the utility of enzalutamide that would likely soon expand the indication to asymptomatic or minimally symptomatic men with mCRPC not previously treated with chemotherapy.

Elements form a basic and natural constituent of the Earth's crust and are released into the atmosphere due to many human activities like mining and manufacturing. Of all, the elements, lead toxicity is a prevailing as well as a growing concern the world over because of its ability to affect multiple clinical functions. Blood lead levels have been analyzed in a large pan-India cohort of 222,668 comprising of 121,115 males and 101,553 females respectively. The cohort included all age groups from <2 to >55 years old. The analytical platform of Inductively Coupled Plasma-Mass Spectrometry has been used to assess lead levels. Blood lead levels of ≥150 μg/L was considered high for analysis. The total frequency of high lead levels detected in our study was 1.16%. The frequency of males affected were higher than females, with the difference being statistically significant.. Lead being ubiquitous in its presence and also serving no biological function, has grown today to become a serious threat to human health. The high frequency of affected detected in our study raises a cause for concern. Determining its presence and the most affected geography in any country will aid in charting guidelines on controlling its release as well as exposure. Copyright © 2015 Elsevier B.V.

The Provision of Healthcare to Young and Dependent Children: The Principles, Concepts, and Utility of the Children Act 1989.

PubMed

Bridgeman, Jo

2017-08-01

This article undertakes a thorough analysis of the case law concerned with the provision of healthcare to young and dependent children. It demonstrates how, despite the procedural changes introduced by the Children Act 1989 at an early stage in this body of case law, cases have continued to be brought to court by way of applications for the court to exercise its inherent jurisdiction or in wardship rather than using the orders introduced by the Act. In determining these cases, the court is focused upon its protective duty to the vulnerable but proceedings appear to be adversarial contests between the claims of adults to know what is best for the child in which the medical view normally prevails. Through consideration of the principles and concepts of the Children Act of parental responsibility, working together, the welfare principle and placing the child at the centre of care, this article demonstrates their utility, as yet to be fully realised, in relation to the responsibilities of parents, professionals, public authorities, and the courts concerned with the provision of healthcare to young and dependent children. © The Author 2017.

Strategic action or self-control? Adolescent information management and delinquency.

PubMed

Grigoryeva, Maria S

2018-05-01

Recent scholarship has begun to challenge the prevailing view that children are passive recipients of parental socialization, including the common belief that parental disciplinary practices are central to explaining adolescent problem behaviors. This research shows that children exert a significant influence over parents via information management, or the degree to which children disclose information about their behavior to parents. Despite the incorporation of child information management into contemporary models of parenting, significant theoretical and empirical concerns cast doubt on its utility over classic parent-centered approaches. The current paper addresses these concerns and adjudicates between disparate definitions of adolescent information management in two ways. First, it provides a theoretically grounded definition of information management as agentic behavior. Second, it specifies a model that tests definitions of secret keeping as agentic against a non-agentic definition of secret keeping supplied by criminological theories of self-control. The model is estimated with three four-wave cross-lagged panel models, which disentangle the interrelationships between parenting, child concealment of information, and child problem behavior in a sample of high risk youth. The results offer support for a definition of concealment as strategic and self-regarding, and have implications for research on delinquency, parent-child interactions, and child agency.

Towards a systematic approach to comparing distributions used in flood frequency analysis

NASA Astrophysics Data System (ADS)

Bobée, B.; Cavadias, G.; Ashkar, F.; Bernier, J.; Rasmussen, P.

1993-02-01

The estimation of flood quantiles from available streamflow records has been a topic of extensive research in this century. However, the large number of distributions and estimation methods proposed in the scientific literature has led to a state of confusion, and a gap prevails between theory and practice. This concerns both at-site and regional flood frequency estimation. To facilitate the work of "hydrologists, designers of hydraulic structures, irrigation engineers and planners of water resources", the World Meteorological Organization recently published a report which surveys and compares current methodologies, and recommends a number of statistical distributions and estimation procedures. This report is an important step towards the clarification of this difficult topic, but we think that it does not effectively satisfy the needs of practitioners as intended, because it contains some statements which are not statistically justified and which require further discussion. In the present paper we review commonly used procedures for flood frequency estimation, point out some of the reasons for the present state of confusion concerning the advantages and disadvantages of the various methods, and propose the broad lines of a possible comparison strategy. We recommend that the results of such comparisons be discussed in an international forum of experts, with the purpose of attaining a more coherent and broadly accepted strategy for estimating floods.

Frailty's Place in Ethics and Law: Some Thoughts on Equality and Autonomy and on Limits and Possibilities for Aging Citizens.

PubMed

McNally, Mary; Lahey, William

2015-01-01

Consideration of ethical and legal themes relating to frailty must engage with the concern that frailty is a pejorative concept that validates and reinforces the disadvantage and vulnerability of aging adults. In this chapter, we consider whether a greater focus on frailty may indeed be part of the solution to the disadvantages that aging adults face in achieving equality and maintaining their autonomy within systems that have used their frailty to deny them equality and autonomy. First, by examining equality both as an ethical norm and as a requirement for protections against discrimination, we raise questions about the grounds on which health providers and health systems can be required to give equal concern and respect to the needs of frail older persons. Second, we explore autonomy and identify the tension between meaningful self-determination and prevailing ethical and legal norms associated with informed choice. Third, we argue that a proper understanding of frailty is essential within both of these themes; it respects equality by enabling health providers and systems to identify and address the distinct care needs of aging adults and helps to align informed choice theory with appropriate processes for decision-making about those needs. 2015 S.

The main aspects of occupational exposure to chromium and chromium compounds are surveyed. Special attention is paid to the toxic action of this metal at the different target organs. The nutritional aspect of CrIII is examined preliminarily, and data detailing the metal contents in water and food are provided. As far the different working processes that entail occupational exposure to chromium are concerned, hygienic and environmental problems are discussed while identifying the average environment exposure to the different chemical forms of chromium (CrIII, CrIV, soluble and not soluble), as a function of the worker's tasks, and the relevant human response (total human Cr). Different hygienic and environmental standards in force in various countries and applicable to chromium compounds are compared. Additional information is given on the main aspects of chromium metabolism (absorption, distribution, excretion), and on the prevailing toxic actions, with specific reference to cancerogenesis. As far as biologic monitoring of the exposed people is concerned, the significance of Cr-U as dose-exposure indicator is discussed, also in the light of a critical review of the reference values. The report describes a series of analytical methods for the identification of chromium in aqueous and biologic matrices. The problems connected with health monitoring and fitness for work are eventually covered.

Patients' attitudes towards privacy in a Nepalese public hospital: a cross-sectional survey.

PubMed

Moore, Malcolm; Chaudhary, Ritesh

2013-01-29

Many people in western countries assume that privacy and confidentiality are features of most medical consultations. However, in many developing countries consultations take place in a public setting where privacy is extremely limited. This is often said to be culturally acceptable but there is little research to determine if this is true. This research sought to determine the attitudes of patients in eastern Nepal towards privacy in consultations. A structured survey was administered to a sample of patients attending an outpatients department in eastern Nepal. It asked patients about their attitudes towards physical privacy and confidentiality of information. The majority of patients (58%) stated that they were not comfortable having other patients in the same room. A similar percentage (53%) did not want other patients to know their medical information but more patients were happy for nurses and other health staff to know (81%). Females and younger patients were more concerned to have privacy. The results challenge the conventional beliefs about patients' privacy concerns in Nepal. They suggest that consideration should be given to re-organising existing outpatient facilities and planning future facilities to enable more privacy. The study has implications for other countries where similar conditions prevail. There is a need for more comprehensive research exploring this issue.

Local Impacts of Mercury Emissions from the Three Pennsylvania Coal Fired Power Plants.

DOE Office of Scientific and Technical Information (OSTI.GOV)

Sullivan,T.; Adams,J.; Bender, M.

2008-02-01

The Clean Air Interstate Rule (CAIR) and the Clean Air Mercury Rule (CAMR) as proposed by the U.S. Environmental Protection Agency (EPA) when fully implemented will lead to reduction in mercury emissions from coal-fired power plants by 70 percent to fifteen tons per year by 2018. The EPA estimates that mercury deposition would be reduced 8 percent on average in the Eastern United States. The CAMR permits cap-and-trade approach that requires the nationwide emissions to meet the prescribed level, but do not require controls on each individual power plant. This has led to concerns that there may be hot-spots ofmore » mercury contamination near power plants. Partially because of this concern, many states including Pennsylvania have implemented, or are considering, state regulations that are stricter on mercury emissions than those in the CAMR. This study examined the possibility that coal-fired power plants act as local sources leading to mercury 'hot spots'. Soil and oak leaf samples from around three large U.S. coal-fired power plants in Western Pennsylvania were collected and analyzed for evidence of 'hot spots'. These three plants (Conemaugh, Homer City, and Keystone) are separated by a total distance of approximately 30 miles. Each emits over 500 pounds of mercury per year which is well above average for mercury emissions from coal plants in the U.S. Soil and oak leaf sampling programs were performed around each power plant. Sampling rings one-mile apart were used with eight or nine locations on each ring. The prevailing winds in the region are from the west. For this reason, sampling was conducted out to 10 miles from the Conemaugh plant which is southeast of the others. The other plants were sampled to a distance of five miles. The objectives were to determine if local mercury hot spots exist, to determine if they could be attributed to deposition of coal-fired power plant emissions, and to determine if they correlated with wind patterns. The study found the following: (1) There was some correlation between the prevailing wind direction and measured soil and oak leaf concentrations. This correlation was not statistically significant, but higher soil concentrations were generally found in the east and southeast from the plants and lower soil concentrations were found west/southwest from the plants. The prevailing winds are to the east. The Conemaugh plant which was the most southeast of the three plants did have the highest average oak leaf and soil mercury concentrations. Based on emissions, the Keystone plant would be expected to see the highest concentrations as it emitted about 25% more mercury than the other two plants. (2) The results of this study did not turn up strong evidence for large areas (several square miles) of elevated mercury concentrations around the three coal-fired power plants that were tested. This does not mean that there is no effect, there was some evidence of increasing mercury content to the east and south of these plants, however, the trends were not statistically significant suggesting that if the effects exist, they are small.« less

Sibling sexual abuse: why don't we talk about it?

PubMed

Yates, Peter

2017-08-01

To explore two hypotheses for explaining why there is little written about sibling sexual abuse and to raise awareness of the subject in order better to protect children and to facilitate sensitive patient care. While there is no universal agreement over its definition, sibling sexual abuse is acknowledged internationally as a prevalent form of child sexual abuse but tends not to be recognised by health professionals. It is also under-represented within the literature in comparison with other forms of intrafamilial sexual abuse. Understanding why this is may help to illuminate the potential barriers to effective professional responses. Two explanations which emerge strongly are the existence of a sibling incest taboo and a prevailing belief that sibling sexual behaviour is largely harmless. Discursive position paper. The paper examines the two hypotheses through exploration of the extant literature on sibling incest and sibling sexual abuse. Sibling sexual abuse accounts for a significant minority of child sexual abuse and has the potential to be as harmful as sexual abuse by a parent. An abhorrence at the thought of sibling sexual activity and a prevailing view of its harmlessness may hinder nurses' detection of and appropriate responses to sibling sexual abuse, but do not provide convincing explanations for the dearth of literature. Instead, a deeply held perspective of sibling relationships as non-abusive offers a more profound explanation. A knowledge of sibling sexual abuse and its consequences are important both for the effective protection of children and the sensitive and appropriate treatment of patients who present with a variety of physical and mental health concerns. A perspective that sibling relationships are non-abusive provides a deeper level of understanding of the powerful obstacles to raising awareness of and responding appropriately to this form of abuse. © 2016 John Wiley & Sons Ltd.

On the theory of intensity distributions of tornadoes and other low pressure systems

NASA Astrophysics Data System (ADS)

Schielicke, Lisa; Névir, Peter

Approaching from a theoretical point of view, this work presents a theory which unifies intensity distributions of different low pressure systems, based on an energy of displacement. Resulting from a generalized Boltzmann distribution, the expression of this energy of displacement is obtained by radial integration over the forces which are in balance with the pressure gradient force in the horizontal equation of motion. A scale analysis helps to find out which balance of forces prevail. According to the prevailing balances, the expression of the energy of displacement differs for various depressions. Investigating the system at the moment of maximum intensity, the energy of displacement can be interpreted as the work that has to be done to generate and finally eliminate the pressure anomaly, respectively. By choosing the appropriate balance of forces, number-intensity (energy of displacement) distributions show exponential behavior with the same decay rate β for tornadoes and cyclones, if tropical and extra-tropical cyclones are investigated together. The decay rate is related to a characteristic (universal) scale of the energy of displacement which has approximately the value Eu = β- 1 ≈ 1000 m 2s - 2 . In consequence, while the different balances of forces cause the scales of velocity, the energy of displacement scale seems to be universal for all low pressure systems. Additionally, if intensity is expressed as lifetime minimum pressure, the number-intensity (pressure) distributions should be power law distributed. Moreover, this work points out that the choice of the physical quantity which represents the intensity is important concerning the behavior of intensity distributions. Various expressions of the intensity like velocity, kinetic energy, energy of displacement and pressure are possible, but lead to different behavior of the distributions.

[Theoretical risk management and legitimacy of the precautionary principle in medicine. Look back at HIV contamination through blood transfusion in France, twenty years ago].

2005-02-01

The precautionary principle first appeared in France during the health crisis following the contamination of patients with HIV via blood transfusion. This study analyses whether the risk associated with blood transfusion was taken into account early enough considering the context of scientific uncertainty between 1982 and 1985. The aim was to evaluate whether a precautionary principle was applied and whether it was relevant. First, we investigated the context of scientific uncertainty and controversies prevailing between 1982 and 1985. Then we analysed the attitude and decisions of the French authorities in this situation to determine whether a principle of precaution was applied. Finally, we explored the reasons at the origin of the delay in controlling the risk. Despite the scientific uncertainties associated with the potential risk of HIV contamination by transfusion in 1983, we found that a list of recommendations aiming to reduce this risk was published in June of that year. In the prevailing climate of uncertainty, these measures could be seen as precautionary. However, the recommended measures were not widely applied. Cultural, structural and economic factors hindered their implementation. Our analysis provides insight into the use of precautionary principle in the domain of blood transfusion and, more generally, medicine. It also sheds light on the expectations that health professionals should have of this principle. The aim of the precautionary principle is to manage rather than to reduce scientific uncertainty. The principle is not a futile search for zero risk. Rather, it is a principle for action allowing precautionary measures to be taken. However, we show that these measures must appear legitimate to be applied. This legitimacy requires an adapted decision-making process, involving all those concerned in the management of collective risks.

Due to concerns about adverse health effects associated with inhalation of atmospheric polycyclic aromatic hydrocarbons (PAHs), 30 ambient air samples were obtained at an air quality monitoring station in Palm Beach County, Florida, from March 2013 to March 2014. The ambient PAH concentration measurements and fractional emission rates of known sources were incorporated into a chemical mass balance model, CMB8.2, developed by EPA, to apportion contributions of three major PAH sources including preharvest sugarcane burning, mobile vehicles, and wildland fires. Strong association between the number of benzene rings and source contribution was found, and mobile vehicles were identified to be the prevailing source (contribution≥56%) for the observed PAHs concentration with lower molecular weights (four or fewer benzene rings) throughout the year. Preharvest sugarcane burning was the primary contributing source for PAHs with relatively higher molecular weights (five or more benzene rings) during the sugarcane burning season (from October to May of the next year). Source contribution of wildland fires varied among PAH compounds but was consistently lower than for sugarcane burning during the sugarcane harvest season. Determining the major sources responsible for ground-level PAHs serves as a tool to improving management strategies for PAH emitting sources and a step toward better protection of the health of residents in terms of exposure to PAHs. The results obtain insight into temporal dominance of PAH polluting sources for those residential areas located near sugarcane burning facilities and have implications beyond Palm Beach County, in areas with high concerns of PAHs and their linked sources. Source apportionment of atmospheric polycyclic hydrocarbons (PAHs) in Palm Beach County, Florida, meant to estimate contributions of major sources in PAH concentrations measured at Belle Glade City of Palm Beach County. Number of benzene rings was found to be the key parameter in determining the source with the prevailing contribution. Mobile vehicle sources showed a higher contribution for species with four or fewer benzene rings, whereas sugarcane burning contributed more for species with five or more benzene rings. Results from this study encourage more control for sugarcane burns and help to better manage authorization of the sugarcane burning incidents and more restrictive transportation plans to limit PAH emissions from mobile vehicles.

Determine stones composition of the upper urinary tract in the eastern region of Algeria. Our study focuses on a set of 359 stones of the upper urinary tract collected between January 2007 and December 2012 at hospitals in the eastern region of Algeria and analyzed by Fourier transform infrared spectroscopy. The male/female ratio was only 1.32. Calcium oxalate prevailed in 68.5% of stones and 49.3% of nuclei, mainly as whewellite (51.8% of stones and 37.9% of nuclei vs 16.7% and 11.4% respectively for weddellite). Carbapatite prevailed in 15% of stones and 29.8% of nuclei. The struvite, identified in 11.1% of calculi, prevailed in 3.9% of stones and 3.1% of nuclei. Among purines, uric acid prevailed with frequencies quite close to 8.9% and 7% respectively in the stone and in the nucleus while the ammonium urate prevailed in only 0.3% of stones and 3.3% of nuclei. The cystine frequency was 3.6% in both stone and nucleus. The frequency of stone with umbilication was 26.2%. Whewellite was the main component of umbilicated stones with Randall's plaque. Our results suggest that stones of the urinary tract in the Algerian east region resemble those observed in industrialized countries. Some features such as stones location, the whewellite prevalence, the frequencies of main components in both the stone and the nucleus as well as the formation of stones on renal papilla confirm this trend. 4.

The Proximate Determinants of Educational Homogamy: The Effects of First Marriage, Marital Dissolution, Remarriage, and Educational Upgrading

PubMed Central

Schwartz, Christine R.; Mare, Robert D.

2014-01-01

This paper adapts the population balancing equation to develop a framework for studying the proximate determinants of educational homogamy. Using data from the National Longitudinal Survey of Youth on a cohort of women born between 1957 and 1964, we decompose the odds of homogamy in prevailing marriages into four proximate determinants: (1) first marriages, (2) first and later marital dissolutions, (3) remarriages, and (4) educational attainment after marriage. The odds of homogamy among new first marriages are lower than among prevailing marriages, but not because of selective marital dissolution, remarriage, and educational attainment after marriage, as has been speculated. Prevailing marriages are more likely to be educationally homogamous than new first marriages because of the accumulation of homogamous first marriages in the stock of marriages. First marriages overwhelmingly account for the odds of homogamy in prevailing marriages in this cohort. Marital dissolutions, remarriages, and educational upgrades after marriage have relatively small and offsetting effects. Our results suggest that, despite the high prevalence of divorce, remarriage, and continued schooling after marriage in the United States, the key to understanding trends in educational homogamy lies primarily in variation in assortative mating into first marriage.

Building public trust in uses of Health Insurance Portability and Accountability Act de-identified data

PubMed Central

2013-01-01

Objectives The aim of this paper is to summarize concerns with the de-identification standard and methodologies established under the Health Insurance Portability and Accountability Act (HIPAA) regulations, and report some potential policies to address those concerns that were discussed at a recent workshop attended by industry, consumer, academic and research stakeholders. Target audience The target audience includes researchers, industry stakeholders, policy makers and consumer advocates concerned about preserving the ability to use HIPAA de-identified data for a range of important secondary uses. Scope HIPAA sets forth methodologies for de-identifying health data; once such data are de-identified, they are no longer subject to HIPAA regulations and can be used for any purpose. Concerns have been raised about the sufficiency of HIPAA de-identification methodologies, the lack of legal accountability for unauthorized re-identification of de-identified data, and insufficient public transparency about de-identified data uses. Although there is little published evidence of the re-identification of properly de-identified datasets, such concerns appear to be increasing. This article discusses policy proposals intended to address de-identification concerns while maintaining de-identification as an effective tool for protecting privacy and preserving the ability to leverage health data for secondary purposes.

Research of inmate social order is a once-vibrant area that receded just as American incarceration rates climbed and the country's carceral contexts dramatically changed. This study reengages inmate society with an abductive mixed methods investigation of informal status within a contemporary men's prison unit. The authors collect narrative and social network data from 133 male inmates housed in a unit of a Pennsylvania medium-security prison. Analyses of inmate narratives suggest that unit "old heads" provide collective goods in the form of mentoring and role modeling that foster a positive and stable peer environment. This hypothesis is then tested with Exponential Random Graph Models (ERGMs) of peer nomination data. The ERGM results complement the qualitative analysis and suggest that older inmates and those who have been on the unit longer are perceived by their peers as powerful and influential. Both analytical strategies point to the maturity of aging and the acquisition of local knowledge as important for attaining informal status in the unit. In sum, this mixed methods case study extends theoretical insights of classic prison ethnographies, adds quantifiable results capable of future replication, and points to a growing population of older inmates as important for contemporary prison social organization.

Experimental evidence of massive-scale emotional contagion through social networks

PubMed Central

Kramer, Adam D. I.; Guillory, Jamie E.; Hancock, Jeffrey T.

2014-01-01

Emotional states can be transferred to others via emotional contagion, leading people to experience the same emotions without their awareness. Emotional contagion is well established in laboratory experiments, with people transferring positive and negative emotions to others. Data from a large real-world social network, collected over a 20-y period suggests that longer-lasting moods (e.g., depression, happiness) can be transferred through networks [Fowler JH, Christakis NA (2008) BMJ 337:a2338], although the results are controversial. In an experiment with people who use Facebook, we test whether emotional contagion occurs outside of in-person interaction between individuals by reducing the amount of emotional content in the News Feed. When positive expressions were reduced, people produced fewer positive posts and more negative posts; when negative expressions were reduced, the opposite pattern occurred. These results indicate that emotions expressed by others on Facebook influence our own emotions, constituting experimental evidence for massive-scale contagion via social networks. This work also suggests that, in contrast to prevailing assumptions, in-person interaction and nonverbal cues are not strictly necessary for emotional contagion, and that the observation of others’ positive experiences constitutes a positive experience for people.

The cyber threat, trophy information and the fortress mentality.

PubMed

Scully, Tim

2011-10-01

'It won't happen to me' is a prevalent mindset among senior executives in the private and public sectors when considering targeted cyber intrusions. This is exacerbated by the long-term adoption of a 'fortress mentality' towards cyber security, and by the attitude of many of our cyber-security professionals, who speak a different language when it comes to communicating cyber-security events to senior executives. The prevailing approaches to cyber security have clearly failed. Almost every week another serious, targeted cyber intrusion is reported, but reported intrusions are only the tip of the iceberg. Why have we got it so wrong? It must be acknowledged that cyber security is no longer the domain of cyber-security experts alone. Many more of us at various levels of leadership must understand, and be more deeply engaged in, the cyber-security challenge if we are to deal with the threat holistically and effectively. Governments cannot combat the cyber threat alone, particularly the so-called advanced persistent threat; they must work closely with industry as trusted partners. Industry will be the 'boots on the ground' in cyber security, but there are challenges to building this relationship, which must be based on sound principles.

A case of Munchausen syndrome by proxy (factitious disorder by proxy) wherein the patient presented with symptoms of severe borderline personality disorder and questionable psychotic symptoms is discussed. This patient was also adjudicated for harassing and stalking a child protective services worker assigned to her case. Issues pertaining to possible feigning of psychotic symptoms were addressed in her inpatient treatment. Despite doubts concerning the veracity of some of her psychotic symptoms, the patient responded well to clozapine, and she was subsequently able to stay out of the psychiatric hospital for longer periods and make a reasonably good adjustment to living in a group home. After refusing to continue with clozapine therapy because of weight gain concerns, her adjustment declined.

Interdisciplinary Collaboration in Medication-Related Falls Prevention in Older Adults.

2018-04-01

The older adult population continues to steadily increase. Largely attributed to longer life spans and aging of the Baby Boomer generation, continued growth of this population is expected to affect a multitude of challenging public health concerns. Specifically, falls in older adults are prevalent but overlooked concerns. Health care providers are well-positioned to provide valuable interventions in this aspect. An interdisciplinary, team-based approach of health care providers is required to maximize falls prevention through patient-centered and collaborative care. The current article highlights the implications of inappropriate medication use and the need to improve care coordination to tackle this public health issue affecting older adults.

To avoid complications associated with plating in anterior cervical discectomy and fusion (ACDF), stand-alone anchored PEEK cage was developed and favourable outcomes with a low rate of dysphasia have been described. The objective of this study was to compare the clinical and radiological outcomes of ACDF using a standalone anchored PEEK cage (PREVAIL; Medtronic Sofamor Danek, Memphis, TN) with those of a PEEK cage with plating in a prospective randomized manner. Fifty patients with single-level cervical radiculopathy were randomly assigned to a PREVAIL or a PEEK cage with plating. Following 3, 6, 12, and 24 months, clinical and radiological outcomes were assessed. The mean surgical time for the patients with a PREVAIL was significantly shorter than that for those with a PEEK cage with plating. The clinical outcomes evaluated by visual analogue scale for pain and the Odom's criteria were comparable between both the groups. Both the groups demonstrated the high fusion rate (92% in PREVAIL; 96% in PEEK cage with plating). The subsidence rate and the improvement of cervical alignment were comparable between both the groups. The incidence of adjacent-level ossification was significantly lower for patients with a PREVAIL than that for those with a PEEK cage with plating. The rate of dysphasia graded by the method of Bazaz and measurement of prevertebral soft tissue swelling indicated no significant differences between both the groups. Our prospective randomized study confirmed that stand-alone anchored PEEK cage is a valid alternative to plating in ACDF with a low rate of adjacent-level ossification. However, the potential to reduce the incidence of dysphasia was not confirmed.

Prevailing surface winds in Northern Serbia in the recent and past time periods; modern- and past dust deposition

This study utilizes four different methodological approaches to examine the prevailing surface winds and their associated aeolian processes in Northern Serbia, focusing on the southeastern part of the Carpathian Basin. We utilized wind and atmospheric pressure data from 1939-2014 and 1960-2010 for the climatological analyses. Geomorphological data and numerical simulations were used to estimate prevailing paleowind systems. Northern Serbia is currently dominated by surface winds coming from the fourth (270°-360°) and second (90°-180°) quadrants, with frequencies of ca. 116 and 105 days/year, respectively. Comparable frequencies within Banatska Peščara are 115 and 129 days/year, respectively. Crestal orientations of the vast majority of the ≈1300 parabolic dunes here suggest that they have formed from winds derived from the second quadrant, indicating formation during the early Holocene. The remaining dunes, of the transverse type, have orientations aligned to the third quadrant. Grain size analysis of loess deposits near Banatska Peščara points to deposition driven by southeasterly winds, probably during the period between the Last Glacial Maximum (LGM) and the early Holocene. Modern wind measurements and geomorphological data showed that the prevailing winds in the recent and past periods were from the same quadrant, in and around Banatska Peščara. These results were confirmed with an explicit numerical simulation that modelled prevailing winds from the second quadrant during the LGM. Thus, the various geomorphologic and climatic data analyzed in this study show that the general air circulation patterns in the recent period are not dissimilar to those operative during the LGM.

Human immunodeficiency virus (HIV) self-testing presents an empowering alternative to facility-based testing for reaching undiagnosed HIV infected individuals, but is not currently available in Canada. We surveyed stakeholders (clinical providers, public health professionals, researchers) engaged in HIV testing initiatives nationwide to identify the concerns, opportunities and challenges to implementing HIV self-testing in Canada. An online cross-sectional survey was disseminated by the Canadian Institutes of Health Research Centre for REACH 2.0 National HIV & sexually transmitted and blood borne infections working group to stakeholders nationwide, with a target sample size of 200. Quantitative and qualitative data were analyzed using a mixed-methods, respondent-informed approach, to inform subsequent HIV self-testing in a country where self-testing is not yet accessible. A total of 183 responses were received. A majority (70.7%) (128/181) felt that self-testing was a necessary investment to reach the undiagnosed. 64.6% (117/181) felt that self-tests should be made available to their clients and 71.5% (128/179) of respondents agreed that self-test instructions required improvements. However, 50% (90/180) felt that self-testing will pose an economic challenge to current HIV testing models. Regardless, 21% urged for timely action and availability of HIV self-tests. Thematic analyses reflected the following concerns: (a) need for affordable self-tests, (b) need for expedited, customized, and accessible linkages to counselling, (c) concern for patients to cope with positive self-test results, (d) accuracy of self-tests to detect acute HIV and (e) liability in the context of non-disclosure. Stakeholders agreed to the provision of an option of HIV self-testing to reach the undiagnosed individuals. Concerns regarding costs and accuracy of self-tests, expedited linkages to counselling, and integration of self-test within prevailing HIV testing models, will need to be addressed before their widespread implementation.

Health insurance and quality of care: Comparing perceptions of quality between insured and uninsured patients in Ghana's hospitals.

The introduction of health insurance in Ghana in 2003 has resulted in a tremendous increase in utilization of health services. However, concerns are being raised about the quality of patient care. Some of the concerns include long waiting times, verbal abuse of patients by health care providers, inadequate physical examination by doctors and discrimination of insured patients. The study compares perceptions of quality of care between insured and uninsured out-patients in selected hospitals in Ghana to determine whether there is any unequal treatment between insured and uninsured patients in terms of quality of care, as empirical and anecdotal evidence seem to suggest. A cross-sectional survey of 818 out-patients was conducted in 17 general hospitals from three regions of Ghana. These are the Upper East, Brong Ahafo and Central Regions. Convenience sampling was employed to select the patients in exit interviews. Descriptive statistics, including frequency distributions, means and standard deviations, were used to describe socio-economic and demographic characteristics of respondents. Factor analysis was used to determine distinct quality of care constructs; t-test statistic was used to test for differences in quality perceptions between the insured and uninsured patients; and regression analysis was used to test the association between health insurance and quality of care. Overall, there was no significant difference in perceptions of quality between insured and uninsured patients. However, there was a significant difference between insured and uninsured patients in respect of financial access to care. The major quality of care concern affecting all patients was the problem of inadequate resources, especially lack of doctors, lack of drugs and other basic supplies and equipment to work with. It was concluded that generally, insured and uninsured patients are not treated unequally, contrary to prevailing anecdotal and empirical evidence. On the contrary, quality of care is a concern of both insured and uninsured patients.

Intra-annual variability of cloud cover over the Mediterranean region based on NCEP/NCAR, MODIS and ECAD data sets

The seasonal variability of total cloud cover in the Mediterranean region is examined for the period 1948-2014 using a multivariate statistical methodology. The data used consist of: i) daily gridded (1.875°x1.905°) values of total cloud cover over the broader Mediterranean region for the 66-year period 1948-2014, obtained from NCEP/NCAR Reanalysis data set, ii) daily gridded (1°x1°) values of total cloud cover for the period 2003-2014 obtained from the Moderate resolution Imaging Spectroradiometer (MODIS) satellite data set and iii) daily station cloud cover data for the period 2003-2014 obtained from the European Climate Assessment & Dataset (ECA&D). At first, the multivariate statistical method of Factor Analysis (S-mode) with varimax rotation is applied as a dimensionality reduction tool on the mean day to day intra-annual variation of NCEP/NCAR cloud cover for the period 1948-2014. According to the results, three main modes of intra-annual variation of cloud cover are found. The first mode is characterized by a winter maximum and a summer minimum and prevails mainly over the sea; a weak see-saw teleconnection over the Alps represents the opposite intra-annual marching. The second mode presents maxima in early autumn and late spring, and minima in late summer and winter, and prevails over the SW Europe and NW Africa inland regions. The third mode shows a maximum in June and a minimum in October and prevails over the eastern part of central Europe. Next, the mean day to day intra-annual variation of NCEP/NCAR cloud cover over the core regions of the above factors is calculated for the entire period 1948-2014 and the three 22-year sub-periods 1948-70, 1970-92 and 1992-2014. A comparison is carried out between each of the three sub-periods and the total period in order to reveal possible long-term changes in seasonal march of total cloud cover. The results show that cloud cover was reduced above all regions during the last 22-year sub-period 1992-2014 throughout the year, but especially in winter. Finally, given the different nature of the utilized NCEP/NCAR (Reanalysis), MODIS (satellite) and ECAD (stations) cloud cover data sets, an inter-comparison is made among them as it concerns the intra-annual variation of cloud cover for the common period 2003-2014. The results show a nice similarity among the three datasets, with some differences in magnitude during the cold period of the year.
