    Detecting aberrant fetal growth has long been an important goal of modern obstetrics. Failure to diagnose abnormal fetal growth results in perinatal morbidity or mortality. However, the erroneous diagnosis of abnormal growth may lead to increased maternal anxiety and unnecessary obstetric interventions. We review the aetiology of deviant fetal growth and its implications both for the neonatal period and later in adult life. We examine maternal factors that may influence fetal growth such as obesity, glycaemic control and body composition. We discuss novel ways to improve our detection of abnormal fetal growth with a view to optimising antenatal care and clinical outcomes. These include using customised centiles or individualised growth assessment methods to improve accuracy. The role of fetal subcutaneous measurements as a surrogate marker of the nutritional status of the baby is also discussed. Finally, we investigate the role of Doppler measurements in identifying growth-restricted babies.

    This paper presents international and temporal extensions of evidence for a theory developed by the author concerning the interaction of transportation technology transitions and macroeconomic growth. The period 1970 to the present is examined for the nations of Japan, the US, and Europe (France, Germany, Italy and the United Kingdom collectively). An addition to the abstract logic supporting the general arguments of the theory is also presented. The theory has been developed concerning the role of significant transportation technology transitions as a cause of significant macroeconomic declines in nations for which the manufacture of transportation vehicles (ships, locomotives, and automobiles) is a dominant economic activity. The theory offers an explanation for periods of pronounced multiyear decline in economic growth rate--sometimes called depressions and sometimes called stagnations. One purpose of this paper is to explore whether or not Japan and Europe have each recently experienced a multiyear event of this type. In the theory and the evidence presented for it, environmental regulation of transportation vehicles has been shown to be an initiating cause of significant technical change, with sharp, sustained fuel price increases being a second frequent initiating cause. These causes of significant technical change, and their possible consequences, are potentially important considerations for those proposing policies to deal with global warming, since both fuel economy regulation and fuel price increases have been recommended by policy analysts as means to reduce transportation`s contribution to global warming. The theory has been offered and supported by publications developing mathematical models and examining US historical evidence consistent with the theory.

    Herbivores are credited with driving the evolutionary diversification of plant defensive strategies over macroevolutionary time. For this to be true, herbivores must also cause short-term evolution within plant populations, but few studies have experimentally tested this prediction. We addressed this gap using a long-term manipulative field experiment where exclosures protected 22 plant populations from natural rabbit herbivory for <1 to 26 years. We collected seeds of Rumex acetosa L. (Polygonaceae) from our plots and grew them in a common greenhouse environment to quantify evolved differences among populations in individual plant growth rate, tolerance to herbivory, competitive ability, and the concentration of secondary metabolites (tannins and oxalate) implicated in defense against herbivores. In 26 years without rabbit herbivory, plant growth rate decreased linearly by 30%. We argue that plant growth rate has evolved as a defense against intense rabbit herbivory. In contrast, we found no change in tolerance to herbivory or concentrations of secondary metabolites. We also found no change in competitive ability, suggesting that contemporary evolution may not feed back to alter ecological interactions within this plant community. Our results combined with those of other studies show that the evolution of gross morphological traits such as growth rate in response to herbivory may be common, which calls into question assumptions about some of the most popular theories of plant defense.

    A total of 648 purebred Holstein and 319 backcross Holstein × Jersey dairy cattle were compared for production, reproduction, health, linear type, and growth traits. Animals were born between 2003 and 2009 and were housed in the University of Wisconsin-Madison Integrated Dairy Facility. All animals had Holstein dams; lactating dams were mated to unproven Holstein sires to produce purebred (control) Holsteins or to unproven F(1) Jersey × Holstein crossbred sires to produce backcross animals, whereas nulliparous dams were mated to proven Holstein sires to produce purebred (other) Holsteins. Traits were analyzed using mixed linear models with effects of season of birth, age of dam, sire, birth year of sire, days in milk, lactation, and linear type score evaluator. Control Holsteins had greater 305-d milk yield (12,645 vs. 11,456 kg), 305-d mature equivalent milk yield (13,420 vs. 12,180 kg), peak daily milk yield (49.5 vs. 46.4 kg), total lactation milk yield (11,556 vs. 10,796 kg), and daily fat-corrected milk yield (43 vs. 40 kg) compared with backcrosses. Days open and services per conception as a heifer or cow did not differ between control Holsteins, other Holsteins, or backcrosses. The proportion of first-parity births that required assistance was less in control Holsteins than in backcross cows (3.7 vs. 11.2%). The incidence of scours or respiratory problems in calves did not differ between control Holsteins, other Holsteins, and backcrosses, nor did the incidence of mastitis, injury, or feet problems. Control Holstein heifers were heavier (629 vs. 557 kg), with greater hip height (145 vs. 139 cm), body length (167 vs. 163 cm), heart girth (205 vs. 198 cm), and hip width (54 vs. 53 cm) at 22 mo of age. On a 50-point scale for linear type traits, Holsteins were larger in stature compared with backcrosses (41 vs. 28), had wider rumps (37 vs. 33), and wider rear udders (34 vs. 32). Results of this study suggest that backcross Holstein × Jersey cattle have

    Rising atmospheric CO2 is increasing the availability of dissolved CO2 in the ocean relative to HCO3−. Currently, many marine primary producers use HCO3− for photosynthesis, but this is energetically costly. Increasing passive CO2 uptake relative to HCO3− pathways could provide energy savings, leading to increased productivity and growth of marine plants. Inorganic carbon-uptake mechanisms in the seagrass Amphibolis antarctica were determined using the carbonic anhydrase inhibitor acetazolamide (AZ) and the buffer tris(hydroxymethyl)aminomethane (TRIS). Amphibolis antarctica seedlings were also maintained in current and forecasted CO2 concentrations to measure their physiology and growth. Photosynthesis of A. antarctica was significantly reduced by AZ and TRIS, indicating utilization of HCO3−-uptake mechanisms. When acclimated plants were switched between CO2 treatments, the photosynthetic rate was dependent on measurement conditions but not growth conditions, indicating a dynamic response to changes in dissolved CO2 concentration, rather than lasting effects of acclimation. At forecast CO2 concentrations, seedlings had a greater maximum electron transport rate (1.4-fold), photosynthesis (2.1-fold), below-ground biomass (1.7-fold) and increase in leaf number (2-fold) relative to plants in the current CO2 concentration. The greater increase in photosynthesis (measured as O2 production) compared with the electron transport rate at forecasted CO2 concentration suggests that photosynthetic efficiency increased, possibly due to a decrease in photorespiration. Thus, it appears that the photosynthesis and growth of seagrasses reliant on energetically costly HCO3− acquisition, such as A. antarctica, might increase at forecasted CO2 concentrations. Greater growth might enhance the future prosperity and rehabilitation of these important habitat-forming plants, which have experienced declines of global significance. PMID:27293673

  10. Cloned cattle fetuses with the same nuclear genetics are more variable than contemporary half-siblings resulting from artificial insemination and exhibit fetal and placental growth deregulation even in the first trimester.

    2004-01-01

    The cloning of cattle by somatic cell nuclear transfer (NT) is associated with a high incidence of abnormal placentation, excessive fluid accumulation in the fetal sacs (hydrops syndrome), and fetal overgrowth. Fetal and placental development was investigated at Day 50, during placentome formation; at Day 100, when placentation was completed; and at Day 150, when the hydrops syndrome frequently develops. The NT fetuses were compared with contemporary half-siblings generated from in vitro-produced embryos or by artificial insemination (AI). Fetal cotyledon formation and vascularization of the chorioallantoic membranes was initiated normally in NT conceptuses, but fewer cotyledons successfully formed placentomes. By Day 100, the mean number of placentomes was significantly lower in surviving NT fetuses. Only those with normal placentome numbers were represented in surviving NT pregnancies at Day 150. The mean total caruncle tissue weight of the placentomes was significantly higher in the surviving NT groups at Days 100 and 150, irrespective of the placentome numbers, indicating that increased NT placental weight was caused by excessive uterine tissue growth. By Day 100, NT fetuses exhibited growth deregulation, and those that survived to Day 150 were 17% heavier than contemporary AI controls. Placentome, liver, and kidney overgrowth accompanied the hydrops syndrome at Day 150. The NT fetal overgrowth was not a consequence of in vitro embryo culture and showed no correlation with placental overgrowth. However, in vitro culture and incomplete reprogramming of the donor genome are epigenetic effects that may override genetic traits and contribute to the greater variability in placental and fetal development in the NT group compared with AI half-siblings.

    In this study, an impaired natural killer (NK) cell cytolytic activity in 135 hepatocellular carcinoma (HCC) patients parallel to a reduced expression level of insulin-like growth factor (IGF)-1 in NK cells of HCC patients has been revealed. Ectopic expression of miR-486-5p, a direct upstream regulator of IGF-1, restored the endogenous level of IGF-1 in NK cells of HCC patients, thus augmenting its cytolytic activity against Huh7 cells in an opposite manner to the IGF-1 siRNAs. Unorthodoxly, over-expression of miR-486-5p in target hepatocytes resulted in the repression of IGF-1, suppression of Huh7 cells proliferation and viability in a similar pattern to the IGF-1 siRNAs. Therefore, this study highlights a potential role of IGF-1 in modulating cytolytic potential of NK cells of HCC patients. miR-486-5p acts in a cell-specific manner, differentially modulating IGF-1 expression in NK cells and their target hepatocytes with a contemporary inhibitory impact on HCC progression.

  18. Charcot in contemporary literature.

    PubMed

    Goetz, Christopher G

    2006-03-01

    Charcot and his medical observations remain an enduring topic of scientific study in neurology, but he is also the topic of modern literary works. This essay examines the depiction of Jean-Martin Charcot (1825-1893) as a character in late-twentieth-century literature as an index of the contemporary nonmedical literary public's interest in neurology and Charcot. It focuses on three contemporary works that involve Charcot as a central figure with comparison between primary source documents and the rendered context, character development, and plot lines of these literary works. The two French novels [Slumbers of Indiscretion and Dr. Charcot of the Salpêtrière] and one American play [Augustine (Big Hysteria)] approach Charcot and neurology with differing levels of historical accuracy. All create a figure of authority, each with a different coloration of the balance between power and its abuse. Two focus almost exclusively on his work with hysteria and inaccurately amplify Charcot's concern with symbolic sexual conflict as the origin of hysteria and fictionalize more extensive interactions with Freud than historical documents support. The three works demonstrate that Charcot retains an enduring fascination with an enigmatic personality, a controversial career, and a pivotal role in the development of studies involving the brain and behavior. Neurologists should not look to these works as replacements for more seriously composed historical studies, but as enrichments anchored in the imaginative possibilities of Charcot and his fin de siècle era.

    The facial nerve is the most commonly paralyzed nerve in the human body. Facial paralysis affects aesthetic appearance, and it has a profound effect on function and quality of life. Management of patients with facial paralysis requires a multidisciplinary approach, including otolaryngologists, plastic surgeons, ophthalmologists, and physical therapists. Regardless of etiology, patients with facial paralysis should be evaluated systematically, with initial efforts focused upon establishing proper diagnosis. Management should proceed with attention to facial zones, including the brow and periocular region, the midface and oral commissure, the lower lip and chin, and the neck. To effectively compare contemporary facial reanimation strategies, it is essential to employ objective intake assessment methods, and standard reassessment schemas during the entire management period.

    Acute promyelocytic leukemia (APL) is characterized by coagulopathy, leukopenic presentation and sensitivity to anthracyclines, all-trans retinoic acid (ATRA) and arsenic trioxide (ATO). For the last 25 years, APL has been treated with a combination of ATRA and chemotherapy for induction followed by consolidation and maintenance therapy. This general treatment approach has resulted in cure rates of 80–90%. ATO, originally approved in relapsed APL, has been incorporated into contemporary upfront treatment regimens with excellent response rates. Recent studies show that most patients with APL can be cured with ATRA and ATO alone, eliminating cytotoxic chemotherapy and resulting in superior outcomes compared to standard treatment. We will herein review historical treatment of APL, treatment considerations in specific patient populations, and therapeutic updates. PMID:24643310

    Most ribosomal antibiotics obstruct distinct ribosomal functions. In selected cases, in addition to paralyzing vital ribosomal tasks, some ribosomal antibiotics are involved in cellular regulation. Owing to the global rapid increase in the appearance of multi-drug resistance in pathogenic bacterial strains, and to the extremely slow progress in developing new antibiotics worldwide, it seems that, in addition to the traditional attempts at improving current antibiotics and the intensive screening for additional natural compounds, this field should undergo substantial conceptual revision. Here, we highlight several contemporary issues, including challenging the common preference of broad-range antibiotics; the marginal attention to alterations in the microbiome population resulting from antibiotics usage, and the insufficient awareness of ecological and environmental aspects of antibiotics usage. We also highlight recent advances in the identification of species-specific structural motifs that may be exploited for the design and the creation of novel, environmental friendly, degradable, antibiotic types, with a better distinction between pathogens and useful bacterial species in the microbiome. Thus, these studies are leading towards the design of "pathogen-specific antibiotics," in contrast to the current preference of broad range antibiotics, partially because it requires significant efforts in speeding up the discovery of the unique species motifs as well as the clinical pathogen identification.

    Measuring sea level change and understanding its causes has considerably improved in the recent years, essentially because new in situ and remote sensing observations have become available. Here we report on most recent results on contemporary sea level rise. We first present sea level observations from tide gauges over the twentieth century and from satellite altimetry since the early 1990s. We next discuss the most recent progress made in quantifying the processes causing sea level change on timescales ranging from years to decades, i.e., thermal expansion of the oceans, land ice mass loss, and land water-storage change. We show that for the 1993-2007 time span, the sum of climate-related contributions (2.85 +/- 0.35 mm year(-1)) is only slightly less than altimetry-based sea level rise (3.3 +/- 0.4 mm year(-1)): approximately 30% of the observed rate of rise is due to ocean thermal expansion and approximately 55% results from land ice melt. Recent acceleration in glacier melting and ice mass loss from the ice sheets increases the latter contribution up to 80% for the past five years. We also review the main causes of regional variability in sea level trends: The dominant contribution results from nonuniform changes in ocean thermal expansion.

    Contemporary surgical management of nonsyndromic craniosynostosis requires the combined expertise of a pediatric craniofacial surgeon and pediatric neurosurgeon. The goals of surgical intervention are the release of the affected suture, which allows for unrestricted development of the visceral components (eg, brain, eyes) and three-dimensional reconstruction of the skeletal components, which establishes a more normal anatomic position and contour. Surgeon who care for infants with these cranial and orbital malformations must maintain a thorough understanding of the three-dimensional anatomy, characteristic dysmorphology associated with the different types of synostosis, and the complex interplay that exists between surgical intervention and ongoing skeletal growth.

  15. Growth

    NASA Astrophysics Data System (ADS)

    Waag, Andreas

    This chapter is devoted to the growth of ZnO. It starts with various techniques to grow bulk samples and presents in some detail the growth of epitaxial layers by metal organic chemical vapor deposition (MOCVD), molecular beam epitaxy (MBE), and pulsed laser deposition (PLD). The last section is devoted to the growth of nanorods. Some properties of the resulting samples are also presented. If a comparison between GaN and ZnO is made, very often the huge variety of different growth techniques available to fabricate ZnO is said to be an advantage of this material system. Indeed, growth techniques range from low cost wet chemical growth at almost room temperature to high quality MOCVD growth at temperatures above 1, 000∘C. In most cases, there is a very strong tendency of c-axis oriented growth, with a much higher growth rate in c-direction as compared to other crystal directions. This often leads to columnar structures, even at relatively low temperatures. However, it is, in general, not straight forward to fabricate smooth ZnO thin films with flat surfaces. Another advantage of a potential ZnO technology is said to be the possibility to grow thin films homoepitaxially on ZnO substrates. ZnO substrates are mostly fabricated by vapor phase transport (VPT) or hydrothermal growth. These techniques are enabling high volume manufacturing at reasonable cost, at least in principle. The availability of homoepitaxial substrates should be beneficial to the development of ZnO technology and devices and is in contrast to the situation of GaN. However, even though a number of companies are developing ZnO substrates, only recently good quality substrates have been demonstrated. However, these substrates are not yet widely available. Still, the situation concerning ZnO substrates seems to be far from low-cost, high-volume production. The fabrication of dense, single crystal thin films is, in general, surprisingly difficult, even when ZnO is grown on a ZnO substrate. However

  16. A climate for contemporary evolution.

    PubMed

    Skelly, David

    2010-01-01

    A new study of divergence in freshwater fish provides strong evidence of rapid, temperature-mediated adaptation. This study is particularly important in the ongoing debate over the extent and significance of evolutionary response to climate change because divergence has occurred in relatively few generations in spite of ongoing gene flow and in the aftermath of a significant genetic bottleneck, factors that have previously been considered obstacles to evolution. Climate change may thus be more likely to foster contemporary evolutionary responses than has been anticipated, and I argue here for the importance of investigating their possible occurrence.

    PubMed

    Kim, Leslie; Byrne, Patrick J

    2016-08-01

    Facial palsy is a devastating condition with profound functional, aesthetic, and psychosocial implications. Although the complexity of facial expression and intricate synergy of facial mimetic muscles are difficult to restore, the goal of management is to reestablish facial symmetry and movement. Facial reanimation surgery requires an individualized treatment approach based on the cause, pattern, and duration of facial palsy while considering patient age, comorbidities, motivation, and goals. Contemporary reconstructive options include a spectrum of static and dynamic procedures. Controversies in the evaluation of patients with facial palsy, timing of intervention, and management decisions for dynamic smile reanimation are discussed. PMID:27400842

  19. Contemporary issues in hydrogels research

    SciTech Connect

    Peppas, N.A.

    1993-12-31

    The last ten years has seen an explosion in hydrogels research, the result of improved understanding of the structure and behavior of these water-swollen, crosslinked polymers. After the early developments of Flory And Katchalsky in the 1940s, the great Czechoslovakian researchers of the 1960s and Andrade, Hoffman, Ratner and Merrill of the early 1970s, hydrogels have again attracted significant research interest, especially through the imaginative research of Tanaka in the 1980s and others. Eight general areas of contemporary research in hydrogels are identified: (i) kinetic analysis of the copolymerization/crosslinking reactions used in hydrogel preparation; (ii) gelation and percolation theories; (iii) novel methods for tailor-made copolymers with desirable functional groups, or biodegradable chains; (iv) biomimetic hydrogels; (V) hydrogels of controlled porous structure; (vi) ultrapure hydrogels devoid of crosslinking agents, emulsifiers, etc.; (vii) critical phenomena in hydrogels; and (viii) behavior of anionic, cationic and amphiphilic hydrogels.

    The Transfusion Medicine Service (TMS) covers diverse clinical and laboratory-based services that must be delivered with accuracy, efficiency and reliability. TMS oversight is shared by multiple regulatory agencies that cover product manufacturing and validation standards geared toward patient safety. These demands present significant informatics challenges. Over the past few decades, TMS information systems have improved to better handle blood product manufacturing, inventory, delivery, tracking and documentation. Audit trails and access to electronic databases have greatly facilitated product traceability and biovigilance efforts. Modern blood bank computing has enabled novel applications such as the electronic crossmatch, kiosk-based blood product delivery systems, and self-administered computerized blood donor interview and eligibility determination. With increasing use of barcoding technology, there has been a marked improvement in patient and specimen identification. Moreover, the emergence of national and international labeling standards such as ISBT 128 have facilitated the availability, movement and tracking of blood products across national and international boundaries. TMS has only recently begun to leverage the electronic medical record to address quality issues in transfusion practice and promote standardized documentation within institutions. With improved technology, future growth is expected in blood bank automation and product labeling with applications such as radio frequency identification devices. This article reviews several of these key informatics issues relevant to the contemporary practice of TMS. PMID:21383927

    Racine, Eric; Waldman, Sarah; Rosenberg, Jarett; Illes, Judy

    2010-08-01

    Technological innovations in neuroscience have opened new windows to the understanding of brain function and the neuronal underpinnings of brain activity in neuropsychiatric disorders and social behavior. Public interest and support for neuroscience research through initiatives like the Decade of the Brain project and increasingly diverse brain-related initiatives have created new interfaces between neuroscience and society. Against this backdrop of dynamic innovation, we set out to examine how different features of neuroscience are depicted in print media. We used the 'guided news' function of the LexisNexis Academic database with keyword searches to find news articles published between 1995 and 2004 in major U.S. and U.K. English-language news sources. We performed searches on headlines, lead paragraphs, and body terms to maximize search yields. All articles were coded for overall tone of coverage, details on reported studies, presence of ethical, legal, and social discussion as well as the emerging interpretations of neuroscience - in the form of neuro-essentialism, neuro-realism, and neuro-policy. We found that print media coverage of the use of neurotechnology for diagnosis or therapy in neuropsychiatric disorders was generally optimistic. We also found that, even within articles that were identified as research reports, many did not provide details about research studies. We also gained additional insights into the previously identified phenomena of neuro-essentialism, neuro-realism, and neuro-policy showing some profound impacts of neuroscience on personal identity and policy-making. Our results highlight the implications of transfer of neuroscience knowledge to society given the substantial and authoritative weight ascribed to neuroscience knowledge in defining who we are. We also discuss the impact of these findings on neuroscience and on the respective contributions of the social sciences and the biological sciences in contemporary psychiatry and mental

  6. Contemporary Treatment Paradigms in Keratoconus.

    PubMed

    McGhee, Charles N J; Kim, Bia Z; Wilson, Peter J

    2015-10-01

    The past 20 years have witnessed an explosion in our knowledge of keratoconus, accompanied by a radical transformation of management options. A 2-hit hypothesis proposes an underlying genetic predisposition coupled with external environmental factors, including eye rubbing and atopy. The variable prevalence and natural history have been better defined including significant cone progression in middle age. Therefore, current management must include early diagnosis, regular monitoring, and treatment of environmental cofactors. Spectacles and contact lenses remain fundamental to the optical management of keratoconus. Intrastromal corneal ring segments have been increasingly used, providing improvement in the corneal shape, corrected visual acuity, and contact lens wear. However, like contact lenses, intrastromal corneal ring segments do not treat the underlying disease process. Therefore, current approaches must also consider treatments to minimize keratoconus progression. Fortunately, there is increasing evidence that corneal collagen crosslinking will halt or slow progression in most cases. Until relatively recently, penetrating keratoplasty was the preferred intervention for advanced keratoconus, with long-term success in the region of 90%; however, the greatest risk of failure remains endothelial allograft rejection. Deep anterior lamellar keratoplasty has emerged in the new millennium as a preferred approach to conserve the host endothelium and avoid rejection. Nonetheless, the overall superiority of deep anterior lamellar keratoplasty compared with penetrating keratoplasty, in terms of optical and survival benefits, is still debated. This perspective provides an overview of our current knowledge of keratoconus and current management options. A step-ladder approach to managing keratoconus is outlined to provide the practitioner with a contemporary management paradigm.

    Wanna, George B; Sweeney, Alex D; Haynes, David S; Carlson, Matthew L

    2015-04-01

    Jugular paragangliomas are generally benign slow-growing tumors that can cause pulsatile tinnitus, hearing loss, and cranial nerves neuropathy. Progressive growth can also lead to intracranial extension. Historically, the treatment of choice for these lesions has been gross total resection. However, over the last 15 years, many groups have adopted less invasive management strategies including stereotactic radiation therapy, subtotal resection, and primary observation in order to reduce treatment-associated morbidity. The focus of this article is to review the modern management of jugular paraganglioma, highlighting the evolving treatment paradigm at the Otology Group of Vanderbilt.

    This paper presents a reconceptualisation of language rights, drawing on historical sources and contemporary practice. It shows that early advocates of rights saw these as limits on the state's ability to deprive citizens of basic liberties. Only later did the concept come to include the requirement that the state be proactive in providing…

    There is no shortage of treatment approaches offered to people with pain. The maze of options presents patients and clinicians with difficult choices. Key to making those choices is evidence of treatment effectiveness provided by clinical trials and systematic reviews. Recent growth in the number of clinical trials and systematic reviews, of both high and low quality, makes it vital that users of this evidence-clinicians, researchers, patients, and policy makers-have the skills and knowledge to critically interpret these studies. In this review, we discuss some contemporary issues regarding evidence of effectiveness derived from clinical trials and systematic reviews-issues that we think are critical to understanding the field. We focus on evidence of treatment effectiveness in pain, although many of these issues are relevant to and transferable across the spectrum of evidence-based practice. PMID:25929527

    Hay, Melissa E; Connelly, Denise M; Kinsella, Elizabeth Anne

    2016-05-01

    Contemporary discourses in the health sciences vary in their treatment of aging bodies and the mind-body relationship, yet our understanding of aging experiences and health care practices can be limited by an overreliance on biomedical or social constructionist approaches alone. This paper offers a conceptual exploration of embodiment as an innovative approach to enhance our understandings of aging bodies and health in physiotherapy practice. Embodiment attends to body and mind, nature and culture, structure and agency, while appreciating differences in aging bodies and health in aging. Conclusions consider embodiment in the practice and disciplinary discourse of contemporary physiotherapy, specifically, considering the ways embodied perspectives can support therapists in their health care practice and relationships with people with aging bodies.

    This article draws on recent research in the medical humanities to analyze two contemporary Chinese films: Zhang Yuan's Sons (1996) and Zhou Xiaowen's The Common People (1998). By portraying psychic and physical anguish in ways that refuse to divorce biology from culture, such films offer rare moral dialogues on biomedical issues and contribute a cross-cultural perspective invaluable to the task of responding to illness and suffering.

    Primary prevention, specifically skin care, is an important principle in Islamic theology just as it is emphasized in contemporary medicine. Many skin diseases can be prevented by a proactive approach to skin care, such as proper hygiene and routine inspections, principles that are constantly highlighted in the Islamic literature. Islam promotes primary prevention of disease, including recommendations for skin care practices. The recommendations for skin care practices in Islamic teachings are analogous to current medical guidelines. Sun avoidance, which is recommended by Islam, is mandatory for diseases such as systemic lupus erythematosus, melasma and skin cancers. Skin care and hygiene practices are recommended in Islam and it is considered an important mechanism for reducing the transmission of infections in modern medicine. The body creases and hair are ideal sites for malicious infestations to grow. The practice of “Wudu” includes washing the hands, feet, and hair with clean water. It is an indispensible part of daily prayers which is mandatory for every Muslim. Oral hygiene is also an integral part of both preventive medicine and Islamic teachings. Genital hygiene, particularly after urination and defecation, is recommended in Islamic teachings and is known to prevent urinary and vaginal infections in contemporary medicine. Male circumcision is an Islamic practice. Recently, it was proven that circumcised men are less likely to have sexually transmitted diseases, including HIV. This paper reviews skin care from an Islamic perspective and its relevance to contemporary medicine by translating the simple self care principles into practical guidelines in everyday use.

The Limits to Growth model, a general equilibrium anti-growth model, is the gloomiest economic model ever constructed. None of the doomsday models, the Malthusian theory, the classical stationary state, the neo-Malthusian medical triage model, the Global 2000 study, are so far reaching in their consequences. The course of events that followed the publication of the "Limits to Growth" in 1972 in the form of 2 oil shocks, food shock, pollution shock, and price shock seemed to bear out formally the gloomy predictions of the thesis with a remarkable speed. The 12 years of economic experience and the knowledge of resource trends postulate that even if the economic pressures visualized by the model are at work they are neither far reaching nor so drastic. Appropriate action can solve them. There are several limitations to the Limits to Growth model. The central theme of the model, which is overshoot and collapse, is unlikely to be the course of events. The model is too aggregative to be realistic.

    The paper strives to elucidate the complex yet intimate relation between spirituality and mental health from contemporary perspectives. The diverse and constantly evolving views that spiritualists and mental health professionals have held toward each other over last century are discussed with special accent on the transpersonal spiritual framework within psychology. The role of spirituality in promoting mental health and alleviating mental illness is highlighted. The paper is concluded with an increasing need to integrate spirituality within the mental health field albeit there are several impediments in achieving the same, which need to be worked through circumspectly.

    The management of acute facial nerve insult may entail medical therapy, surgical exploration, decompression, or repair depending on the etiology. When recovery is not complete, facial mimetic function lies on a spectrum ranging from flaccid paralysis to hyperkinesis resulting in facial immobility. Through systematic assessment of the face at rest and with movement, one may tailor the management to the particular pattern of dysfunction. Interventions for long-standing facial palsy include physical therapy, injectables, and surgical reanimation procedures. The goal of the management is to restore facial balance and movement. This article summarizes a contemporary approach to the management of facial nerve insults.

    SCUBA diving is a popular recreational sport. Although serious injuries occur infrequently, when they do knowledge of diving medicine and/or where to obtain appropriate consultation is essential. The emergency physician is likely to be the first physician contact the injured diver has. We discuss 8 subjects in diving medicine which are contemporary, yet may have controversies associated with them. From this information the physician dealing primarily with the injured diver will have a basis for understanding and managing, as well as where to find additional help, for his/her patients' diving injuries.

    Tales around the World give visibility to local, national and international fundamental connection that always existed between people and the night sky that means Astronomy. In this paper we discuss and analyze further the role of Astronomy Education for achieving an integrated concept of education, one that enables individuals to adapt to a rapidly changing social, economic and cultural environment, and to continue to learn throughout life. It is no longer enough to learn how to read, write and count. We also discuss and present initiatives undertaken in the context of various national, and international educational projects in Greece as best practices on how Astronomy Education can actually reinforce the Contemporary Education.

    Sexually transmitted infections continue to be a severe health problem in contemporary Western societies, despite the considerable funds allocated for control programs. In this article, we present and discuss a variety of explanations that have been advanced on why this type of disease is so hard to eradicate, despite the fact that the contact by which it is spread is far less frequent than is the case with most other infectious diseases. We conclude that several processes and mechanisms facilitate the spread of sexually infected diseases, and that both broad and targeted intervention is therefore needed to eradicate such diseases.

    This article applies a contemporary Kleinian understanding to the problem of racism and, in particular, to microaggressions. The article contributes to the social work literature on racism by (1) moving closer to an explanatory model of the relation between the social and the psyche; (2) adding depth and structure to the concept of unconscious racism; and (3) highlighting a range of Kleinian concepts, such as projection, projective identification, splitting, developmental positions, envy, and reparation, that contribute to understanding the internal and external dimensions of racialized encounters. The dynamic interaction of the psyche and the social is central to understanding racism and to effective antiracist intervention strategies.

  4. What is urban in the contemporary world?

    PubMed

    Monte-Mór, Roberto Luís

    2005-01-01

    Central concepts of contemporary life such as politics, civilization, and citizenship derive from the city's form and social organization. The city expresses the socio-spatial division of labor, and Henri Lefebvre proposes to view its transformation within a continuum from the political city to the urban, whereby it completes its domination over the countryside. The city's transformation into the urban takes place when industry brings production (and the proletariat) into that space of power. The city, locus of surplus, power, and the fiesta, a privileged scenario for social reproduction, was subordinated to the industrial logic and underwent a dual process: its centrality imploded, and its outskirts exploded on surrounding areas through the urban fabric, bearing with it the seeds of the polis and civitas. The urban praxis, formerly restricted to the city, re-politicized social space as a whole. In Brazil, the urban has its origins in the military governments' centralizing and integrating policies, following Vargas's expansionism and Kubitschek's developmental interiorization (or occupation of the hinterlands). Today, urban-industrial processes impose themselves over virtually all social space, in contemporary extended urbanization.

    Childhood obesity represents not only a health risk but results also in social exclusion and stigmatization. While several studies have been conducted on this topic in America [1-3], there are hardly any German trials on the social impact of obesity in childhood and adolescence. This study investigates whether and how obese children and adolescents are stigmatized by their contemporaries because of their corpulence. A total of 454 (230 female, 224-male) children and adolescents aged 10-15 years from high and secondary modern schools in a Southern German university city were asked about how they appreciate their obese contemporaries. The interviewees were asked to assess six photographs of girls and boys with regard to sympathy, playmate preference, activity, intelligence and attractiveness. Obese children were assessed far more negatively in all asked areas compared to normal weight healthy and physically disabled children respectively. They were also referred to as more dislikable, lazy, less intelligent, unalluring and less considerable as playmates. This applies particularly for the obese boy. Hence, negative stereotypization of obese people can already be observed in childhood and adolescence.

    The present study addresses the distinction between contemporary and old-fashioned prejudice using survey data from a national sample (n=600) of self-identified whites living in the United States and interviewed by telephone in 2001. First, we examine associations among indicators of contemporary and old-fashioned prejudice. Consistent with the literature, contemporary and old-fashioned prejudice indicators represent two distinct but correlated common factors. Second, we examine whether belief in genetic race differences uniformly predicts both types of prejudice. As might be expected, belief in genetic race differences predicts old-fashioned prejudice but contrary to recent theorizing, it also predicts contemporary prejudice. PMID:20076765

    As the evidence for warming climate became better established in the latter part of the 20th century (IPCC 2001), some scientists raised the alarm that large quantities of methane (CH4) might be liberated by widespread destabilization of climate-sensitive gas hydrate deposits trapped in marine and permafrost-associated sediments (Bohannon 2008, Krey et al. 2009, Mascarelli 2009). Even if only a fraction of the liberated CH4 were to reach the atmosphere, the potency of CH4 as a greenhouse gas (GHG) and the persistence of its oxidative product (CO2) heightened concerns that gas hydrate dissociation could represent a slow tipping point (Archer et al. 2009) for Earth's contemporary period of climate change.

    The Bhagavad Gita is based on a discourse between Lord Krishna and Arjuna at the inception of the Kurukshetra war and elucidates many psychotherapeutic principles. In this article, we discuss some of the parallels between the Gita and contemporary psychotherapies. We initially discuss similarities between psychodynamic theories of drives and psychic structures, and the concept of three gunas. Arjuna under duress exhibits elements of distorted thinking. Lord Krishna helps remedy this through a process akin to Cognitive Behavioral Therapy (CBT). We ascertain the analogies between the principles of Gita and CBT, grief emancipation, role transition, self-esteem, and motivation enhancement, as well as interpersonal and supportive psychotherapies. We advocate the pragmatic application of age old wisdom of the Gita to enhance the efficacy of psychotherapeutic interventions for patients from Indian subcontinent and to add value to the art of western psychotherapies.

  9. Contemporary art and the ethics of anatomy.

    PubMed

    Barilan, Y Michael

    2007-01-01

    The ethics of anatomy bears on the ways in which we present and behold human bodies and human remains, as well as on the duties we have with regard to the persons whose bodies or body parts are presented. Anatomy is also a mode of thought and of social organization. Following Merleau-Ponty's assertion that the human body belongs both to the particular and to the metaphysical, I contend that art's ways of rendering of the particular in human anatomy often bring into relief metaphysical and ethical insights relevant to clinical medicine. This paper discusses the art of Gideon Gechtman, Mary Ellen Mark, Shari Zolla, and Christine Borland. It considers the relationship of these artists to earlier artistic traditions and the implications of their work for contemporary medicine and the biopsychosocial paradigm. Andrew Wyeth, the Visible Male Project, the Isenheim Altarpiece by GrA(1/4)newald, and an anonymous Dutch Baroque portrait are also discussed. PMID:17259679

    Contemporary Electronics is an advanced undergraduate lecture and laboratory introduction to analog and digital electronics. Fundamentals of analog measurements, analog data collection, and digital data collection are included in this one-semester course. Laboratory exercises introduce diodes, transistors, operational amplifiers, and their use in simple circuits. Focus and continuity are provided by the construction of a printed circuit board nanoammeter. The nanoammeter is used to measure the tunneling current generated by a commercial field emission electron microscope. An introduction to LABVIEW programming allows each student to create a "virtual instrument" for data collection and analysis. An analysis of the tunneling data using Fowler-Nordheim theory is the focus of a midterm and a final exam.

    2009-01-01

    The preoccupation of philosophy with madness can be traced back till the Greek antiquity. For many philosophers like Descartes psychotic phenomena were symbols for the fragility of human mental powers, while others like Plato or Nietzsche saw madness as a way to escape the constraints of rationality. After 1960 three direction of contemporary philosophy dealt with the topics madness--schizophrenia--psychosis: Following Nietzsche and Bataille, Foucault as well as Deleuze and Guattari considered schizophrenia as the societal oppressed reverse of modern rationality, a notion which had a strong influence on the anti-psychiatric movement. Philosophical phenomenology primarily focussed on ontological problems of the psychotic existence. Finally Philosophy of Mind, the modern Anglo-American version of analytical philosophy, analyzed the logical coherence of psychotic inferences and experiences. Especially the insights of analytical philosophy may be important for a more sophisticated interpretation of psychopathological research as well as of the new findings of neuroscience.

    The paper presents a simple method of avoiding singular configurations of contemporary industrial robot manipulators of such renowned companies as ABB, Fanuc, Mitsubishi, Adept, Kawasaki, COMAU and KUKA. To determine the singular configurations of these manipulators a global form of description of the end-effector kinematics was prepared, relative to the other links. On the basis of this description , the formula for the Jacobian was defined in the end-effector coordinates. Next, a closed form of the determinant of the Jacobian was derived. From the formula, singular configurations, where the determinant's value equals zero, were determined. Additionally, geometric interpretations of these configurations were given and they were illustrated. For the exemplary manipulator, small corrections of joint variables preventing the reduction of the Jacobian order were suggested. An analysis of positional errors, caused by these corrections, was presented

    In terms of group theory—the language of symmetries, the concept of spontaneous symmetry breaking is represented in terms of chains of group-subgroup structures that define the dynamical symmetry of the system under consideration. This framework enables exact analytic solutions of the associated eigenvalue problems. We review two types of applications of dynamical symmetries in contemporary theoretical nuclear structure physics: first for a classification of the many-body systems under consideration, with respect to an important characteristic of their behavior; and second for the creation of exactly solvable algebraic models that describe specific aspects of this behavior. This is illustrated with the boson and fermion realizations of symplectic structures. In the first case with an application of the sp(4, R) classification scheme of even-even nuclei within the major nuclear shells and next with of the sp(4) microscopic model for the description of isovector pairing correlations.

    PubMed

    Sandberg, Larry S; Busch, Fredric N

    2012-09-01

    A contemporary perspective on psychotherapy and pharmacotherapy views both treatments as somatic in nature. Abandoning Cartesian dualism frees the clinician to consider therapeutic options based on the best available evidence rather than falsely dichotomizing approaches as biological or psychological. Evidence-based medicine is a helpful though limited paradigm upon which to base treatment decisions. Instead, clinicians should strive for an evidence-informed approach that is patient centered. This approach is illustrated in relation to depressive illness where moderators of outcome are examined (illness severity, history of trauma, personality disorders, patient preference) that will influence clinical recommendations on combining treatment. Psychotherapy is increasingly proving to be a valuable therapeutic modality across the severity spectrum, a finding at odds with current treatment practices.

    Evans, Jack B.

    2005-09-01

    Contemporary medical facilities, whether for diagnosis, treatment or research, must accommodate the needs of humans and medical instruments or equipment. With regard to acoustics, the disparate requirements vary from acoustic privacy to freedom from intrusive noise, to vibration control. Medical facilities also grow and change, subjecting occupants to demolition and construction disturbances. Acoustical criteria employed in building designs are often inadequate to control the full spectral range of requirements, although criteria for many conditions do exist. This paper presents interesting problems and conditions that occur in healthcare and research facilities with brief case studies to illustrate them, including construction disturbances, tonal noise affects on patients, privacy, and vibration and low frequency noise affects on medical equipment. Measurement data will contrast ambient versus disturbed conditions. Solution concepts to example problems will be presented with photo or drawing illustrations. Discussion will include typical conflicts, constraints, limitations and compromises. Concluding remarks will suggest application of appropriate and comprehensive acoustical, noise and vibration criteria.

  17. Aquinas and Contemporary Cosmology: Creation and Beginnings

    NASA Astrophysics Data System (ADS)

    Carroll, William E.

    Discussions in the Middle Ages about creation and the temporal beginning of the world involved sophisticated analyses in theology, metaphysics, and natural philosophy. Mediaeval insights on this subject, especially Thomas Aquinas' defense of the intelligibility of an eternal, created universe, can help to clarify reflections about the philosophical and theological implications of contemporary cosmological theories: from the "singularity" of the Big Bang, to "quantum tunneling from nothing," to multiverse scenarios. Thomas' insights help us to see the value of Georges Lemaître's insistence that his cosmological reflections must be kept separate from an analysis of creation. This essay will look at different senses of "beginning" and examine the claim that creation, in its fundamental meaning, tells us nothing about whether there is a temporal beginning to the universe. Multiverse models, like that recently proposed by Stephen Hawking and Leonard Mlodinow, may challenge certain views of a Grand Designer, but not of a Creator.

    2016-06-01

    Intracranial atherosclerotic disease is the most common cause of cerebral vasculopathy and an important stroke etiology worldwide, with a higher prevalence in Asian, Hispanic and African ethnicities. Symptomatic intracranial atherosclerotic disease portends a recurrent stroke risk as high as 18% at one year. The key to secondary prevention is an understanding of the underlying stroke mechanism and aggressive control of conventional cardiovascular risks. Contemporary treatment includes antiplatelet therapy, optimal glycemic and blood pressure control, statin therapy and lifestyle modifications. For patients with high-grade (70-99%) symptomatic steno-occlusion, short-term dual antiplatelet therapy with aspirin and clopidogrel followed by life-long single antiplatelet therapy may reduce the recurrent risk. Current evidence does not advocate percutaneous transluminal angioplasty and stenting as an initial treatment. External counterpulsation, encephaloduroarteriosynangiosis and remote limb ischemic preconditioning are treatments under investigation. Future studies should aim at predicting patients prone to recurrence despite of medical therapies and testing the efficacy of emerging therapies.

    Rothman, H B; Diaz, J A; Vincent, K E

    2000-06-01

    This study is an attempt to ascertain if singers from different traditions and milieus follow similar aesthetic trends regardless of training and/or background. Cantors who sang the Jewish synagogue liturgy during the Golden Age of cantorial singing prior to World War II came from Eastern and Central Europe. For the most part, they were not trained in the classical Western opera tradition. They received training from choir leaders and other cantors and the training was primarily in the modes of synagogue chant. Cantors today receive the same kinds of training that opera singers receive, often from the same teachers. Four groups of singers, consisting of four singers in each group, were utilized in this study. The four groups are: historical opera singers, contemporary opera singers, historical cantors, and contemporary cantors. The historical opera singer recordings date from as early as 1909 to as late as 1939. It was not possible to determine the dates of the historical cantor recordings. However, the four cantors chosen for this group were active only to the 1940s. Contemporary samples were taken from CDs and/or live recordings and all the singers from the contemporary groups are either still active or were active in the 1960s through the 1980s and all of them are considered to be premier-level singers in their respective areas. The variables analyzed were: vibrato pulse rate, frequency variation of the vibrato pulse above and below the mean sustained sung frequency in percent, the mean amplitude variation of the amplitude vibrato pulse above and below the mean sustained amplitude in percent and the fast Fourier transform (FFT) power spectrum of the sustained samples. Results indicate that most of the significant differences were found between eras and not between groups within a time period. PMID:10875572

  11. Codes of medical ethics: traditional foundations and contemporary practice.

    The Hippocratic Coprus recognized the interaction of 'business' and patient-health moral considerations, and urged that the former be subordinated to the latter. During the 1800s with the growth of complexity in both scientific knowledge and the organization of health services, the medical ethical codes addressed themselves to elaborate rules of conduct to be followed by the members of the newly emerging national medical associations. After World War II the World Medical Association was established as an international forum where national medical associations could debate the ethical problems presented by modern medicine. The International Code of Medical ethics and the Declaration of Geneva were written as 20th century restatements of the medical profession's commitment to the sovereignty of the patient-care norm. Many ethical statements have been issued by the World Medical Association in the past 35 years; they show the variety and difficulties of contemporary medical practice. The newest revisions were approved by the General Assembly of the World Medical Association in Venice, Italy October 1983. Their content is examined and concern is voiced about the danger of falling into cultural relativism when questions about the methods of financing medical services are the subject of an ethical declaration which is arrived at by consensus in the W.M.A. PMID:3529416

    Although Neanderthals are extinct, fragments of their genomes persist in contemporary humans. Here we show that while the genome-wide frequency of Neanderthal-like sites is approximately constant across all contemporary out-of-Africa populations, genes involved in lipid catabolism contain more than threefold excess of such sites in contemporary humans of European descent. Evolutionally, these genes show significant association with signatures of recent positive selection in the contemporary European, but not Asian or African populations. Functionally, the excess of Neanderthal-like sites in lipid catabolism genes can be linked with a greater divergence of lipid concentrations and enzyme expression levels within this pathway, seen in contemporary Europeans, but not in the other populations. We conclude that sequence variants that evolved in Neanderthals may have given a selective advantage to anatomically modern humans that settled in the same geographical areas. PMID:24690587

    Foundry practices are used in contemporary world to produce large volume of components and products. Foundry practices involve the melting of metals and pouring the molten metal into the cavities called molds. On solidification, the metals which assume the shape of molds are removed as castings. Foundries that employ these practices were growing in large number till the middle part of the twentieth century in the world. After the middle part of the twentieth century, the world community begun to realize that, foundries were emitting pollutants which were affecting the health of humans. In order to overcome this situation, several countries in the world promulgated laws stipulating the maximum level of pollutants that can emit by foundries. These laws affected the functioning and growth of foundries. In order to sustain amidst these constraints, foundries begun to install energy efficient melting technologies and pollution control devices (PCDs). In this back ground, this paper reports to assess the contemporary scenario and project the future needs for sustaining the foundries. During the conduct of this literature review, it was discernable that, research papers have reported three categories of researches. In the first category of research papers, the researches reporting the achievement of cleaner production technologies in foundries using PCDs have appeared. In the second category of research papers, the application of cleaner production technology in foundries located in different countries has been examined. In the third category of research papers, the application of efficient melting technologies and PCDs in different clusters of foundries located in different parts of world has been explored. Subsequently implementation technics of Environmental Management System in cleaner production technics in foundries has been described the analysis of the information and knowledge drawn from these three categories of papers has revealed that, researches exploring the

    2012-01-01

    The link between music and astronomy has deep historical roots. William Herschel, who is considered to be the father of modern astronomy, began his career as a musician. He was a composer, organist at a church in Bath, UK, and a major contributor to the musical life of that community. Like Herschel, I too am an organist and composer, and much of my creative work focuses on connections between music and astronomy. This presentation will explore briefly aspects of William Herschel's musical career, and will then focus on contemporary music inspired by astronomical phenomena. Emphasis will be placed on the use of music as a creative teaching tool in informal education environments. The University of Arizona's Astronomy Camp, hosted at both Mt. Lemmon and Kitt Peak National Observatory, will be used as an example and case study. Examples from my creative activity as an organ performer and composer will be important features of this presentation. This presentation builds on the session exploring the life and work of the Herschels at the January 2011 AAS Historical Astronomy Division meeting in Seattle, WA.

  16. Contemporary Research of Dynamically Induced Phase Transitions

    2015-06-01

    Dynamically induced phase transitions in metals, within the present discussion, are those that take place within a time scale characteristic of the shock waves and any reflections or rarefactions involved in the loading structure along with associated plastic flow. Contemporary topics of interest include the influence of loading wave shape, the effect of shear produced by directionality of the loading relative to the sample dimensions and initial velocity field, and the loading duration (kinetic effects, hysteresis) on the appearance and longevity of a transformed phase. These topics often arise while considering the loading of parts of various shapes with high explosives, are typically two or three-dimensional, and are often selected because of the potential of the transformed phase to significantly modify the motion. In this paper, we look at current work on phase transitions in metals influenced by shear reported in the literature, and relate recent work conducted at Los Alamos on iron's epsilon phase transition that indicates a significant response to shear produced by reflected elastic waves. A brief discussion of criteria for the occurrence of stress induced phase transitions is provided. Closing remarks regard certain physical processes, such as fragmentation and jet formation, which may be strongly influenced by phase transitions.

    1988-01-01

    Foodborne disease has become a contemporary issue. Several large, well-publicized outbreaks of foodborne disease have heightened public awareness that harmful microorganisms may be present in food and that chronic as well as acute disease may be caused by foodborne microbes. The field of food microbiology has likewise experienced a resurgence of interest. New tools, such as recombinant deoxyribonucleic acid technology and monoclonal antibody production, used to elucidate microbial virulence factors have facilitated identification of disease-causing microbes once thought to be harmless and demonstrated the complexity of individual virulence mechanisms previously considered to be well understood. Foodborne pathogens are also causing disease via some surprising food vectors, such as chopped, bottled garlic and sauteed onions. In addition to acute gastrointestinal disturbances, certain microorganisms may, through complex interactions with the human immune response, cause chronic diseases that affect several major organ systems. These microbes are serving as models in studies of molecular mimicry and genetic interrelatedness of procaryotes and eucaryotes. Other recently recognized attributes of foodborne microorganisms, such as the heat shock phenomenon and the possible nonculturability of some bacteria, may affect their ability to cause disease in humans. Because foodborne disease is a major cause of morbidity and mortality, the study of these diseases and their causative microorganisms presents a unique challenge to many professionals in the subdisciplines of microbiology, epidemiology, and clinical medicine.

    Students not familiar with chemistry tend to misinterpret analytical chemistry as some kind of the sorcery where analytical chemists working as modern wizards handle magical black boxes able to provide fascinating results. However, this approach is evidently improper and misleading. Therefore, the position of modern analytical chemistry among sciences and in the contemporary world is discussed. Its interdisciplinary character and the necessity of the collaboration between analytical chemists and other experts in order to effectively solve the actual problems of the human society and the environment are emphasized. The importance of the analytical method validation in order to obtain the accurate and precise results is highlighted. The invalid results are not only useless; they can often be even fatal (e.g., in clinical laboratories). The curriculum of analytical chemistry at schools and universities is discussed. It is referred to be much broader than traditional equilibrium chemistry coupled with a simple description of individual analytical methods. Actually, the schooling of analytical chemistry should closely connect theory and practice.

  19. Contemporary spirituality: a call to wholeness.

    PubMed

    Coleman, H

    1986-06-01

    Our society and thus our health care organizations are beset by a dualistic perspective that identifies some groups as embodying "masculine" characteristics that are desirable, implying that other groups are less valuable. This perspective, visible in ageism, sexism, and racism, threatens the call to live and heal as Jesus lived and healed, which is the cornerstone of the Catholic health care ministry. A contemporary wholistic spirituality must be articulated that emphasizes individual responsibility for living as a person who believes in the dignity of all persons created by God. Modifying the language of health care is one way to better reflect a wholistic orientation. Two expressions that require special attention are "health care provider" and "patient." Substituting "health care promoter" and "client" for these terms would emphasize the health care ministry's role in helping persons with health care needs to be involved in the healing process. Since a health care organization's effectiveness depends on its members' commitment to healing, it is imperative that the organization's values be modeled and communicated to the members through the organization's decisions and activities. It likewise is important that those involved in the healing ministry reflect on their spirituality, their relationships with self, God, and others, to monitor those values that affect their relationships and experiences.

    2015-01-01

    The accelerated greying of its population along with birth rates plummeting below replacement levels synergise into one of the most acute social issues in contemporary Japan. Although singleness, childlessness, delayed marriage and late-in-life-childbirth have become endemic, official records nevertheless reveal an increase in childbirth among women aged 15-19 in 2013. Furthermore, official statistics for 2010 show that 50% of Japanese women aged 25 or younger who married were expecting a baby. This paper focuses on 17 Japanese mothers who had a 'shotgun wedding' (dekichatta kekkon)--a ceremony organised due to an unplanned pregnancy. Aged between 29 and 35 years, the mothers came from Tokyo and Kanagawa and were interviewed for the purposes of exploring their experiences with and viewpoints on unplanned childbirth, contraception and marriage. Grounded in a symbolic interactionist perspective, the analysis of interviews suggested that shotgun weddings largely stem from contraception issues, the will to get pregnant in order to keep a partner and homosocial pressure to prevent the termination of the unexpected pregnancy.

  1. Contemporary perspectives on Lacanian theories of psychosis

    Redmond, Jonathan D.

    2013-01-01

    In contemporary Lacanian psychoanalysis, Verhaeghe's theory of actualpathology psychopathology in psychosis and the Millerian idea of “ordinary psychosis” provide diverging conceptual approaches to psychosis. In this paper, the two approaches to psychosis are examined with a particular emphasis on “mild psychosis” and compensatory mechanisms. Despite the shared focus on similar clinical phenomena, particularly body disturbances, these two theories provide different explanations of psychosis. Verhaeghe's theory of psychosis is a synthesis of Lacanian theory, Freud's idea of actual neurosis and psychoanalytic attachment concepts. Moreover, these ideas are situated in the “schizophrenia/paranoia dichotomy” an important heuristic device utilized in clinical practice with psychosis. In contrast, the Millerian field of ordinary psychosis aims to broaden the idea of psychosis by reviving the idea of “mild psychosis” and the different forms of stabilization possible in psychosis. Clinicians adapting the idea of ordinary psychosis aim to rethink pivotal Lacanian concepts—“untriggered” psychosis and stabilization—beyond the scope of the schizophrenia/paranoia dichotomy. Although the idea of ordinary psychosis requires further development, it promise greater utility than Verhaeghe's model, as it provides a broader and more nuanced approach to the complex vicissitudes of triggering and restitution in psychosis.

    The polymerization shrinkage of composite resins may affect negatively the clinical outcome of the restoration. Extensive research has been carried out to develop new formulations of composite resins in order to provide good handling characteristics and some dimensional stability during polymerization. The purpose of this study was to analyze, in vitro, the magnitude of the volumetric polymerization shrinkage of 7 contemporary composite resins (Definite, Suprafill, SureFil, Filtek Z250, Fill Magic, Alert, and Solitaire) to determine whether there are differences among these materials. The tests were conducted with precision of 0.1 mg. The volumetric shrinkage was measured by hydrostatic weighing before and after polymerization and calculated by known mathematical equations. One-way ANOVA (á=0.05) was used to determine statistically significant differences in volumetric shrinkage among the tested composite resins. Suprafill (1.87±0.01) and Definite (1.89±0.01) shrank significantly less than the other composite resins. SureFil (2.01±0.06), Filtek Z250 (1.99±0.03), and Fill Magic (2.02±0.02) presented intermediate levels of polymerization shrinkage. Alert and Solitaire presented the highest degree of polymerization shrinkage. Knowing the polymerization shrinkage rates of the commercially available composite resins, the dentist would be able to choose between using composite resins with lower polymerization shrinkage rates or adopting technical or operational procedures to minimize the adverse effects deriving from resin contraction during light-activation.

    2011-01-01

    Contemporary medicine is a large and complex system involving many participants, all of whom play a critical role in managing the risks intrinsic to medical product use. Despite the robust premarket review and approval process of the U.S. Food and Drug Administration (FDA), new information will inevitably be learned in the postmarketing period about the safety of medicines and how they are and should be used. For much of this information, FDA relies on public reports about possible adverse events. In turn, the public depends on FDA to communicate the most up-to-date safety information on medical products to better inform treatment decisions. Expanding the scope and strengthening the capabilities of the drug safety surveillance system are among key FDA projects designed to reduce avoidable injury and death from medication use. Although improving drug safety is our goal and obligation to the public, FDA cannot protect the public adequately without the active involvement of all participants in healthcare. PMID:20809798

    Cordero, Alberto

    2009-06-01

    This paper discusses the impact of contemporary scientific knowledge on worldviews. The first three sections provide epistemological background for the arguments that follow. Sections 2 and 3 discuss the reliable part of science, specifically the characterization, scope and limits of the present scientific canon. Section 4 deals with the mode of thinking responsible for both the canon’s credibility and its power to guide speculative activity. With these preliminaries in place, the remainder of the paper addresses the issue of tolerance to “alternative perspectives”. The analyses in this part focus on the extent to which mature scientific thought embodies open-mindedness, with pluralism and competition between perspectives as central themes. I argue for four related claims, concerning scientific literacy, the impact of the canon on rational speculation, the limits of scientific pluralism, and the popular idea that recent forms of “scientific (natural) theology” have rational merit and can help worldview-making in our age, respectively: (C1) Which theories and narratives (or parts of them) belong in the scientific canon, and whether they are worldview independent, are matters contingent upon the state of knowledge—not something one can convincingly determine on metascientific or transcendental insight. (C2) The current scientific canon and its associated methodology provide research with strong directionality, often against popular currents. (C3) Current science does marginalize some views dear to many people. (C4) Although natural theology “officially” purports to embody scientific methodology, all it presently has on offer are poorly thought out ventures embodying (at best) only relaxed versions of that methodology; if so, the relationship between current projects in natural theology and science cannot (without begging the question) be reasonably described as one of “partial overlap”, “mutual modification”, or “ongoing complementarity”.

    The prevalence of cribra orbitalia (CO) is often used as an indicator of the general health status of past populations. Although debates as to its exact etiology are still ongoing, cribra is generally accepted to be the result of an anemic condition. Cribra has been reported to be declining in modern populations or even to be absent. The aim of this study was to compare modern, historic, and prehistoric prevalences of CO to assess whether it has changed through time and if it still occurs in contemporary populations. CO in skeletons (n = 844) from two widely different regions, the northeastern US and the central Gauteng area of South Africa, were compared in order to evaluate temporal trends. The sample comprised 245 prehistoric, 381 historic, and 218 modern skeletons. In adult skeletons the prevalence was found to be lower in historic South Africans (2.23%) than in historic North Americans (6.25%). It was lower in modern North Americans than in modern South Africans (12.35 and 16.8%, respectively). Its prevalence in prehistoric North Americans (11.86%) was also not much different from that of modern North Americans (12.35%). The frequency of CO in historic South African juveniles was higher (10.71%) than in historic North American juveniles (1.35%). Modern South African children had a lower frequency (25.14%) than modern American juveniles (40%), although the sample in the North American group was small. It seems that CO is still present in modern populations, and that health may indeed have declined for some groups in recent times. Clin. Anat. 29:823-830, 2016. © 2016 Wiley Periodicals, Inc.

  6. Health action to meet contemporary challenges.

    1988-01-01

    While India has made rapid strides in building its medical manpower and medical service, yet many of the major health problems are far from being controlled. Although earlier Health problems have not been resolved, newer threats to health through misguided development are getting superadded. The major health threats today are the denial of minimal sustenance base, such as adequate food and water to an increasing number of people. The rapidly increasing uncontrolled chemicalization of body and environment is another health hazard. Experience has shown that health needs cannot be satisfied merely by expansion of the medical industry. Health care work would have to involve an attempt to arrest the growing threats to health and survival, and rebuilding of the ecological base, to ensure provision of basic needs to all. These efforts would be towards a new economics, because they include radical shifts in food agriculture policy, resources use policy, industrial policy etc and can only be guided by a deep sense of social justice and human concern. Contemporary health care work has increasingly to involve those who are already looking for alternatives e.g., those involved in ecology movements, feminist movement, peace and civil rights groups, those involved in alternative education, agriculture, health care journalism. Priority has to be given and strategies evolved to help add a health dimension, to various health or non health work and initiatives already existing, with a special effort to safeguard the traditional health care knowledge systems from total disintegration. Grass root level feed back should constitute an essential pre-requisite for any (health) policy formulation and its implementation.

  7. A contemporary definition and classification of hydrocephalus.

    PubMed

    Rekate, Harold L

    2009-03-01

    This review focuses on the problems related to defining hydrocephalus and on the development of a consensus on the classification of this common problem. Such a consensus is needed so that diverse research efforts and plans of treatment can be understood in the same context. The literature was searched to determine the definition of hydrocephalus and to identify previously proposed classification schemes. The historic perspective, purpose, and result of these classifications are reviewed and analyzed. The concept of the hydrodynamics of cerebrospinal fluid (CSF) as a hydraulic circuit is presented to serve as a template for a contemporary classification scheme. Finally, a definition and classification that include all clinical causes and forms of hydrocephalus are suggested. The currently accepted classification of hydrocephalus into "communicating" and "noncommunicating" varieties is almost 90 years old and has not been modified despite major advances in neuroimaging, neurosciences, and treatment outcomes. Despite a thorough search of the literature using computerized search engines and bibliographies from review articles and book chapters, I identified only 6 previous attempts to define and classify different forms of hydrocephalus. This review proposes the following definition for hydrocephalus: hydrocephalus is an active distension of the ventricular system of the brain related to inadequate passage of CSF from its point of production within the ventricular system to its point of absorption into the systemic circulation. Based on this definition (potential points of flow restriction) and on the view of the CSF system as a hydraulic circuit, a classification system is proposed. The acceptance of this proposed definition and classification schema would allow clinicians and basic scientists to communicate effectively, to share information and results, and to develop testable hypotheses.

  8. Contemporary issues in Australian midwifery regulation.

    PubMed

    Brodie, P; Barclay, L

    2001-01-01

    This paper reports on research that examined the Nurses' Acts, regulations and current policies of each state and territory in Australia, in order to determine their adequacy in regulating the education and practice of midwifery. This is part of a three-year study (Australian Midwifery Action Project) set up to identify and investigate barriers to midwifery within the provision of mainstream maternity services in Australia. Through an in-depth examination and comparison of key factors in the various statutes, the paper identifies their effect on contemporary midwifery roles and practices. The work assessed whether the current regulatory system that subsumes midwifery into nursing is adequate in protecting the public appropriately and ensuring that minimum professional standards are met. This is of particular importance in Australia, where many maternity health care services are seeking to maximise midwives' contributions through the development of new models of care that increase midwives' autonomy and level of accountability. A lack of consistency and evidence of discrepancies in the standards of midwifery education and practice regulation nationally are identified. When these are considered alongside the planned development of a three-year Bachelor of Midwifery, due to be introduced into Australia in mid-2002, there exists an urgent need for regulatory change. The need is also identified for appropriate national midwifery competency standards that meet consumer, employer and practitioner expectations, which can be used to guide state and territory regulations. We argue the importance of a need for change in the view and legal positioning of the Australian Nursing Council and all Nurses Boards regarding the identification of midwifery as distinct from nursing, and substantiate it with a rationale for a national and consistent approach to midwifery regulation.

    The impact of folate on health and disease, particularly pregnancy complications and congenital malformations, has been extensively studied. Mandatory folic acid fortification therefore has been implemented in multiple countries, resulting in a reduction in the occurrence of neural tube defects. However, emerging evidence suggests increased folate intake may also be associated with unexpected adverse effects. This literature review focuses on contemporary issues of concern, and possible underlying mechanisms as well as giving consideration the future direction of mandatory folic acid fortification. Folate fortification has been associated with the presence of unmetabolized folic acid (PteGlu) in blood, masking of vitamin B12 deficiency, increased dosage for anti-cancer medication, photo-catalysis of PteGlu leading to potential genotoxicity, and a role in the pathoaetiology of colorectal cancer. Increased folate intake has also been associated with twin birth and insulin resistance in offspring, and altered epigenetic mechanisms of inheritance. Although limited data exists to elucidate potential mechanisms underlying these issues, elevated blood folate level due to the excess use of PteGlu without consideration of an individual’s specific phenotypic traits (e.g. genetic background and undiagnosed disease) may be relevant. Additionally, the accumulation of unmetabolized PteGlu may lead to inhibition of dihydrofolate reductase and other enzymes. Concerns notwithstanding, folic acid fortification has achieved enormous advances in public health. It therefore seems prudent to target and carefully monitor high risk groups, and to conduct well focused further research to better understand and to minimize any risk of mandatory folic acid fortification.

    Cosmic impacts pose a continuing hazard of loss of human life and property. Significant contemporary risk is associated with projectiles in the energy range from about 10 megatons of TNT up to the size of the K/T impactor. The lower threshold for damage is defined by the atmosphere of the Earth, which effectively shields us From smaller projectiles. Up to energies of about a gigaton of TNT, the effects are local or regional for impacts on the land, or coastal for ocean impacts, which can generate large tsunamis. A greater risk is associated with still larger impacts, which are capable of causing global ecological catastrophe, possibly leading to mass mortality From starvation and epidemics. If such a impact took place anywhere on Earth during our lifetimes, we would each be in danger, independent of where the projectile struck. Statistical estimates indicate that each human on this planet runs a risk of roughly 1 in 20,000 of dying from this cause. Prudence suggests that we should be concerned about such impacts and seek ways of avoiding them or mitigating their consequences. The primary objective of any program to deal with this hazard is to determine whether or not such a near-term impact is likely. The best approach for the asteroidal component is a comprehensive telescopic survey, which can discover all Earth-crossing asteroids larger than 1 km in diameter and provide decades of warning in which to plan ways to deflect or destroy a threatening object. Long-period comets, however, pose a much greater challenge, since they cannot be discovered long in advance of a possible impact, their orbits are harder to predict, and they are significantly more difficult to deflect or destroy.

  11. Contemporary fault mechanics in southern Alaska

    NASA Astrophysics Data System (ADS)

    Kalbas, James L.; Freed, Andrew M.; Ridgway, Kenneth D.

    Thin-shell finite-element models, constrained by a limited set of geologic slip rates, provide a tool for evaluating the organization of contemporary faulting in southeastern Alaska. The primary structural features considered in our analysis are the Denali, Duke River, Totschunda, Fairweather, Queen Charlotte, and Transition faults. The combination of fault configurations and rheological properties that best explains observed geologic slip rates predicts that the Fairweather and Totschunda faults are joined by an inferred southeast-trending strike-slip fault that crosses the St. Elias Mountains. From a regional perspective, this structure, which our models suggest slips at a rate of ˜8 mm/a, transfers shear from the Queen Charlotte fault in southeastern Alaska and British Columbia northward to the Denali fault in central Alaska. This result supports previous hypotheses that the Fairweather-Totschunda connecting fault constitutes a newly established northward extension of the Queen Charlotte-Fairweather transform system and helps accommodate right-lateral motion (˜49 mm/a) of the Pacific plate and Yakutat microplate relative to stable North America. Model results also imply that the Transition fault separating the Yakutat microplate from the Pacific plate is favorably oriented to accommodate significant thrusting (23 mm/a). Rapid dip-slip displacement on the Transition fault does not, however, draw shear off of the Queen Charlotte-Fairweather transform fault system. Our new modeling results suggest that the Totschunda fault, the proposed Fairweather-Totschunda connecting fault, and the Fairweather fault may represent the youngest stage of southwestward migration of the active strike-slip deformation front in the long-term evolution of this convergent margin.

  12. A review of contemporary ideomotor theory.

    A framework for action planning, called ideomotor theory, suggests that actions are represented by their perceivable effects. Thus, any activation of the effect image, either endogenously or exogenously, will trigger the corresponding action. We review contemporary studies relating to ideomotor theory in which researchers have investigated various manipulations of action effects and how those effects acquire discriminative control over the actions. Evidence indicates that the knowledge about the relation between response and effect is still a critical component even when other factors, such as stimulus-response or response-response relations, are controlled. When consistent tone effects are provided after responses are made, performance in serial-reaction tasks is better than when the effects are random. Methodology in which acquisition and test stages are used with choice-reaction tasks shows that an action is automatically associated with its effect bilaterally and that anticipation of the effect facilitates action. Ideomotor phenomena include stimulus-response compatibility, in which the perceptual feature of the stimulus activates its corresponding action code when the stimulus itself resembles the effect codes. For this reason, other stimulus-driven action facilitation such as ideomotor action and imitation are treated as ideomotor phenomena and are reviewed. Ideomotor theory also implies that ongoing action affects perception of concurrent events, a topic which we review briefly. Issues concerning ideomotor theory are identified and evaluated. We categorize the range of ideomotor explanations into several groups by whether intermediate steps are assumed to complete sensorimotor transformation or not and by whether a general theoretical framework or a more restricted one is provided by the account.

  18. The future historian: Reflections on the archives of contemporary sciences.

    PubMed

    2016-02-01

    Historians working on recent science work close to where the archives are created or become accessible. Based on this experience, the essay presents a reflection on the archives of contemporary life sciences. It addresses three questions: firstly, what is special about the archival situation of contemporary sciences? Secondly, which sources do contemporary historians use and what opportunities and challenges do they offer? And finally, what potential changes to the archives of contemporary sciences are we witnessing? The essay draws a distinction between, on the one side, the history of science when the actors are still alive-a situation that presents a particular set of issues in respect to the available sources-and, on the other side, questions relating specifically to the life sciences at the turn of the millennium--a period which will eventually not be considered as 'contemporary' any more. It reviews changes in scientific practice, historiographical trends and archival practices and considers the place of paper records, digital sources, material artefacts and oral sources in the archives of contemporary sciences. It argues that the commercialisation and privatisation of science may prove a bigger problem for the future historian than the shift to the digital medium. It concludes by welcoming the closer interactions between scientists, historians, curators and archivists prompted by recent developments.

    Corneal neovascularization (NV), the excessive ingrowth of blood vessels from conjunctiva into the cornea, is a common sequela of disease insult that can lead to visual impairment. Clinically, topical steroid, argon laser photocoagulation, and subconjunctival injection of bevacizumab have been used to treat corneal NV. Sometimes, the therapies are ineffective, especially when the vessels are large. Large vessels are difficult to occlude and easily recanalized. Scientists and physicians are now dedicated to overcoming this problem. In this article, we briefly introduce the pathogenesis of corneal NV, and then highlight the existing animal models used in corneal NV research-the alkali-induced model and the suture-induced model. Most of all, we review the potential therapeutic targets (i.e., vascular endothelial growth factor and platelet-derived growth factor) and their corresponding inhibitors, as well as the immunosuppressants that have been discovered in recent years by corneal NV studies.

    There is no diet that is recommended for all individuals. Some special diets (eg, gluten-free for celiac disease) are necessary for health and quality of life. Other diets may be recommended for a short period of time to aid in symptom relief but may not be recommended for the long- term (eg, LFD). Popular diets continue to come and go with varying levels of success. When considering adolescents, continued growth and development are most important, and restrictive diets can lead to nutrient inadequacies and poor growth. Before making any recommendation, it is important to consider the goal of the diet and the cost versus benefits associated with following the diet. Adherence is always a challenge, regardless of the type of diet implemented. If a special diet is not warranted for the health, safety, and desired quality of life of the individual, it should not be implemented. PMID:27363236

    Primary teeth play a critical role in the growth and development of a child. In addition to their role in esthetics, eating, speech, and to encourage normal function and resultant expected growth, the other main function of a primary tooth is to hold space for the permanent successor until it is ready to erupt. Space maintenance forms an integral part of preventive and interceptive orthodontics. After the premature loss of a tooth, not only do space maintainers maintain function and preserve arch length, they also maintain esthetics and eliminate any potential psychological damage a child could face as a result of the premature loss of teeth. The space maintainer also allows the permanent tooth to erupt unhindered into proper alignment and occlusion.

    This study investigates the relationship between economic trends and entry into marriage in a rapidly developing setting. We examine Indonesian marriage in the 1990’s, a decade of substantial economic growth followed by a sudden financial collapse in 1998. We use discrete-time hazard models to analyze information on 4,078 women and 4,496 men from the Indonesia Family Life Survey. While previous research has shown that marriages may be postponed after economic downturn, we find no evidence of such delays at the national level following the 1998 financial crisis. In contrast, we use regional wage rate data to show that entry into marriage is inversely related to economic growth throughout the decade for all women and for men from lower socioeconomic strata.

    2014-09-01

    Uterine fibroids (leiomyomata) are extremely common lesions that are associated with detrimental effects including infertility and abnormal uterine bleeding. Fibroids cause molecular changes at the level of endometrium. Abnormal regulation of growth factors and cytokines in fibroid cells may contribute to negative endometrial effects. Understanding of fibroid biology has greatly increased over the last decade. Although the current armamentarium of Food and Drug Administration-approved medical therapies is limited, there are medications approved for use in heavy menstrual bleeding that can be used for the medical management of fibroids. Emergence of the role of growth factors in pathophysiology of fibroids has led researchers to develop novel therapeutics. Despite advances in medical therapies, surgical management remains a mainstay of fibroid treatment. Destruction of fibroids by interventional radiological procedures provides other effective treatments. Further experimental studies and clinical trials are required to determine which therapies will provide the greatest benefits to patients with fibroids.

It assesses the development pattern that prevailed between 1940 and 1970 and the ways and policies that were instrumental in accommodating the rapid population growth of the period. The author considers that by 1970 the relatively acceptable demo-economic system in place since 1940 entered a period of emerging tensions, and examines the responses to those difficulties, among them the change in population policy. It closes with a brief review of the tasks ahead considering future demographic and economic tendencies in Mexico. PMID:2740942

  6. Growth hormone and growth?

    PubMed

    Harvey, Steve

    2013-09-01

    Pituitary GH is obligatory for normal growth in mammals, but the importance of pituitary GH in avian growth is less certain. In birds, pituitary GH is biologically active and has growth promoting actions in the tibia-test bioassay. Its importance in normal growth is indicated by the growth suppression following the surgical removal of the pituitary gland or after the immunoneutralization of endogenous pituitary GH. The partial restoration of growth in some studies with GH-treated hypophysectomized birds also suggests GH dependency in avian growth, as does the dwarfism that occurs in some strains with GHR dysfunctions. Circulating GH concentrations are also correlated with body weight gain, being high in young, rapidly growing birds and low in slower growing older birds. Nevertheless, despite these observations, there is an extensive literature that concludes pituitary GH is not important in avian growth. This is based on numerous studies with hypophysectomized and intact birds that show only slight, transitory or absent growth responses to exogenous GH-treatment. Moreover, while circulating GH levels correlate with weight gain in young birds, this may merely reflect changes in the control of pituitary GH secretion during aging, as numerous studies involving experimental alterations in growth rate fail to show positive correlations between plasma GH concentrations and the alterations in growth rate. Furthermore, growth is known to occur in the absence of pituitary GH, as most embryonic development occurs prior to the ontogenetic appearance of pituitary somatotrophs and the appearance of GH in embryonic circulation. Early embryonic growth is also independent of the endocrine actions of pituitary GH, since removal of the presumptive pituitary gland does not impair early growth. Embryonic growth does, however, occur in the presence of extrapituitary GH, which is produced by most tissues and has autocrine or paracrine roles that locally promote growth and development

  7. Stratification of women's sport in contemporary China.

    2011-01-01

    Since economic reform in the 1980s, Chinese sport has undergone an extraordinary transformation. The most distinguishing phenomenon is the rapid growth of mass sport at the grassroots level with increasing demands for physical activities in women's daily lives. The rapid growth of women's sports participation at the grassroots is deeply embedded in the process of social stratification as a result of the urbanisation of Chinese society. The purpose of this paper is to use the socialist, feminist and theoretical framework to explore how Chinese women's different economic, educational, domestic and cultural situations shape their sports values and patterns of participation, marking social boundaries in Chinese urban communities. Semi-structured interviews and observations were conducted with 60 female physical exercisers in sports clubs, parks and neighbourhood playgrounds. Documentary research was also applied as a complement method to the interview. The findings indicate that within different classes (middle class, working class and a group who were unemployed), many different opportunities for and limitations on women to participate in sport are noticed. Chinese women have not fully and equally utilised sports opportunities created by urbanisation. Most Chinese women still live within patriarchal arrangements. Consequently, they do not completely fulfil their ambitions in sport.

    The vast number and variety of erosion lesions encountered today require reconsideration of the traditional definition. Dental erosion associated with modern dietary habits can exhibit unique features that symbolize a departure from the decades-old conventional image known as tooth surface loss. The extent and diversity of contemporary erosion lesions often cause conflicting diagnoses. Specific examples of these features are presented in this article. The etiologies, genesis, course of development, and characteristics of these erosion lesions are discussed. Contemporary and conventional erosion lesions are distinguished from similar defects, such as mechanically induced wear, carious lesions, and dental fluorosis, which affect the human dentition.

    It is difficult to find a visual representation of any fat individual, let alone a queer woman, that is not denigrating and oppressive in conventional media outlets and contemporary visual culture. But even as the negative imagery of fat individuals has expanded over the past forty years in mainstream distribution channels, fat-positive imagery has come to the fore within many feminist and lesbian publications during this same time frame. This article looks at the strategies of representation taken by three contemporary United States lesbian feminist periodicals in visualizing fat and lesbian women within their pages since the 1980s.

    In an earlier series of papers by the author it was proposed that photochemical weathering of Fe(2+) in magnetite and in mafic silicates may be occurring in the contemporary surface environment with a resultant loss of O2 from the atmosphere. Morris and Lauer challenged the photochemical weathering model, proposing that oxidation by radiant heating rather than UV photoelectron emission induced oxidation may have dominated in the authors experiments. Subsequent laboratory studies of photochemical weathering of magnetite described here support the authors original proposal that UV illunimation can indeed drive the oxidation of magnetite under contemporary Martian surface conditions. The negative results of the Morris and Lauer study can now be explained.

    This article advances nursing research by presenting transnationalism as a framework for inquiry with contemporary immigrants. Transnationalism occurs when immigrants maintain relationships that transcend the geographical borders of their origin and host countries. Immigrants use those relationships to experience health differently within concurrent socioeconomic, political, and cultural contexts than national situated populations. Nurse researchers are called upon to consider these trans-border relationships when exploring the health of contemporary immigrants. Such consideration is needed to develop relevant research designs, methods, analysis, and dissemination strategies. PMID:26836998

    Interacting threats to ecosystem function, including climate change, wildfire, and invasive species necessitate native plant restoration in desert ecosystems. However, native plant restoration efforts often remain unguided by ecological genetic information. Given that many ecosystems are in flux from climate change, restoration plans need to account for both contemporary and future climates when choosing seed sources. In this study we analyze vegetative responses, including mortality, growth, and carbon isotope ratios in two blackbrush (Coleogyne ramosissima) common gardens that included 26 populations from a range-wide collection. This shrub occupies ecotones between the warm and cold deserts of Mojave and Colorado Plateau ecoregions in western North America. The variation observed in the vegetative responses of blackbrush populations was principally explained by grouping populations by ecoregions and by regression with site-specific climate variables. Aridity weighted by winter minimum temperatures best explained vegetative responses; Colorado Plateau sites were usually colder and drier than Mojave sites. The relationship between climate and vegetative response was mapped within the boundaries of the species–climate space projected for the contemporary climate and for the decade surrounding 2060. The mapped ecological genetic pattern showed that genetic variation could be classified into cool-adapted and warm-adapted ecotypes, with populations often separated by steep clines. These transitions are predicted to occur in both the Mojave Desert and Colorado Plateau ecoregions. While under contemporary conditions the warm-adapted ecotype occupies the majority of climate space, climate projections predict that the cool-adapted ecotype could prevail as the dominant ecotype as the climate space of blackbrush expands into higher elevations and latitudes. This study provides the framework for delineating climate change-responsive seed transfer guidelines, which are

    Mechanical circulatory support has seen numerous advances in the recent years, with important observations made to guide patient selection for the therapy, indications for use, and management of devices after implantation. There is rapid growth in the use of left ventricular assist device therapy (LVAD) for advanced heart failure, with a movement to pursue device intervention earlier in the disease spectrum before comorbidities escalate. With this increase in LVAD use have come new challenges, including unanticipated adverse events and high readmission rates. Simultaneously, complications encountered during LVAD support and an increased number of patients supported with a goal for transplant have had an important effect on the allocation of cardiac allografts. Still, the field continues to evolve and address these challenges in systematic fashion to provide novel solutions and meet the needs of a growing population with advanced heart failure. This has led to an extensive body of literature, ranging from case reports to multicenter clinical trials, which will enhance the future of LVAD technology and patient outcomes. This review summarizes important publications in mechanical circulatory support during the past 24 months. PMID:24721183

    The introduction of targeted therapy has revolutionized the treatment of patients with metastatic renal cell carcinoma (mRCC). The current standard of care focuses on the inhibition of angiogenesis through the targeting of the vascular endothelial growth factor receptor (VEGFR) and the mammalian target of rapamycin (mTOR). Over the past few years, research exploring novel targeted agents has blossomed, leading to the approval of various targeted therapies. Furthermore, results from the CheckMate025 and the METEOR trials have brought about two additional novel options: the programmed cell death 1 (PD-1) checkpoint inhibitor nivolumab and the MET/VEGFR/AXL inhibitor cabozantinib, respectively. With the variety of therapeutic agents available for treatment of mRCC, research examining appropriate sequencing and combinations of the drugs is ongoing. This review discusses the role of prognostic criteria, such as those from the International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) criteria. It also covers the current standard of treatment for mRCC with targeted therapy in first-, second-, and third-line setting. Additionally, the novel mechanism of action of nivolumab and cabozantinib, therapeutic sequencing and ongoing clinical trials are discussed. PMID:27471582

    Polycystic ovary syndrome is a multi-system endocrinopathy with long-term metabolic and cardiovascular health consequences. Patients typically present due to symptoms of irregular menstruation, hair growth, or infertility; however, recent management options are aimed at further treating underlying glucose-insulin abnormalities as well as androgen excess for proactive control of symptoms. By a 2003 international consensus conference, diagnosis is made by two out of three criteria: chronic oligoovulation or anovulation after excluding secondary causes, clinical or biochemical evidence of hyperandrogenism (but not necessarily hirsutism due to inter-patient variability in hair follicle sensitivity), and radiological evidence of polycystic ovaries. Traditional medical treatment options include oral contraceptive pills, cyclic progestins, ovulation induction, and anti-androgenic medications (aldosterone antagonist, 5alpha-reductase antagonist, and follicle ornithine decarboxylase inhibitor). Recent pharmacotherapies include insulin-sensitizing medications metformin and two thiazolidinediones (rosiglitazone/Avandia and pioglitazone/Actos), a CYP19 aromatase inhibitor (letrozole/Femara), and statins to potentially lower testosterone levels.

    2015-07-01

    Genetic variation and contemporary evolution within populations can shape the strength and nature of species interactions, but the relative importance of these forces compared to other ecological factors is unclear. We conducted a field experiment testing the effects of genotypic variation, abundance, and presence/absence of green peach aphids (Myzus persicae) on the growth, leaf nitrogen, and carbon of two plant species (Brassica napus and Solanum nigrum). Aphid genotype affected B. napus but not S. nigrum biomass explaining 20 and 7% of the total variation, respectively. Averaging across both plant species, the presence/absence of aphids had a 1.6× larger effect size (Cohen's d) than aphid genotype, and aphid abundance had the strongest negative effects on plant biomass explaining 29% of the total variation. On B. napus, aphid genotypes had different effects on leaf nitrogen depending on their abundance. Aphids did not influence leaf nitrogen in S. nigrum nor leaf carbon in either species. We conducted a second experiment in the field to test whether contemporary evolution could affect plant performance. Aphid populations evolved in as little as five generations, but the rate and direction of this evolution did not consistently vary between plant species. On one host species (B. napus), faster evolving populations had greater negative effects on host plant biomass, with aphid evolutionary rate explaining 23% of the variation in host plant biomass. Together, these results show that genetic variation and evolution in an insect herbivore can play important roles in shaping host plant ecology. PMID:25740334

    2013-03-01

    This paper evaluates the association between income and physical development in a nationally representative sample of contemporary US schoolchildren followed from kindergarten to eighth grade (average ages of 6-14). A generalized linear mixed modeling framework is used to evaluate height and body mass index (BMI) as both levels and annualized growth in a pooled sample. Contemporary US schoolchildren show income variation in height that is significant but modest at around .1cm (in kindergarten) to .4cm (eighth grade) increases per doubling of income. An exception is found for Hispanic children who show faster height velocity associated with higher income through childhood yielding a 1.0cm increase per doubling of income by the eighth grade. All groups except black males show a negative relationship between income and BMI that becomes stronger with age with an average .8kg/m(2) lower BMI per doubling of income by the eighth grade. These results are robust to the inclusion of baseline anthropometric controls. The analysis suggests that higher-income US schoolchildren enter mid-adolescence as taller but with lower proportional body mass relative to their lower-income counterparts.

  19. Low birth weight of contemporary African Americans: an intergenerational effect of slavery?

    PubMed

    Jasienska, Grazyna

    2009-01-01

    The average birth weight in the contemporary African-American population is about 250 g lower than the average birth weight of European Americans. Differences in genetic and socioeconomic factors present between these two groups can explain only part of birth weight variation. I propose a hypothesis that the low birth weight of contemporary African Americans not only results from the difference in present exposure to lifestyle factors known to affect fetal development but also from conditions experienced during the period of slavery. Slaves had poor nutritional status during all stages of life because of the inadequate dietary intake accompanied by high energetic costs of physical work and infectious diseases. The concept of "fetal programming" suggests that physiology and metabolism including growth and fat accumulation of the developing fetus, and, thus its birth weight, depend on intergenerational signal of environmental quality passed through generations of matrilinear ancestors. I suggest that several generations that have passed since the abolition of slavery in the United States (1865) has not been enough to obliterate the impact of slavery on the current biological and health condition of the African-American population.

  11. The contemporary mindfulness movement and the question of nonself1.

    PubMed

    Samuel, Geoffrey

    2015-08-01

    Mindfulness-based stress reduction (MBSR), mindfulness-based cognitive therapy (MBCT), and other "mindfulness"-based techniques have rapidly gained a significant presence within contemporary society. Clearly these techniques, which derive or are claimed to derive from Buddhist meditational practices, meet genuine human needs. However, questions are increasingly raised regarding what these techniques meant in their original context(s), how they have been transformed in relation to their new Western and global field of activity, what might have been lost (or gained) on the way, and how the entire contemporary mindfulness phenomenon might be understood. The article points out that first-generation mindfulness practices, such as MBSR and MBCT, derive from modernist versions of Buddhism, and omit or minimize key aspects of the Buddhist tradition, including the central Buddhist philosophical emphasis on the deconstruction of the self. Nonself (or no self) fits poorly into the contemporary therapeutic context, but is at the core of the Buddhist enterprise from which contemporary "mindfulness" has been abstracted. Instead of focussing narrowly on the practical efficacy of the first generation of mindfulness techniques, we might see them as an invitation to explore the much wider range of practices available in the traditions from which they originate. Rather, too, than simplifying and reducing these practices to fit current Western conceptions of knowledge, we might seek to incorporate more of their philosophical basis into our Western adaptations. This might lead to a genuine and productive expansion of both scientific knowledge and therapeutic possibilities.

  7. Relevance of the Flexner Report to contemporary medical education in South Asia.

    Amin, Zubair; Burdick, William P; Supe, Avinash; Singh, Tejinder

    2010-02-01

    A century after the publication of Medical Education in the United States and Canada: A Report to the Carnegie Foundation for the Advancement of Teaching (the Flexner Report), the quality of medical education in much of Asia is threatened by weak regulation, inadequate public funding, and explosive growth of private medical schools. Competition for students' fees and an ineffectual accreditation process have resulted in questionable admission practices, stagnant curricula, antiquated learning methods, and dubious assessment practices. The authors' purpose is to explore the relevance of Flexner's observations, as detailed in his report, to contemporary medical education in South Asia, to analyze the consequences of growth, and to recommend pragmatic changes. Major drivers for growth are the supply-demand mismatch for medical school positions, weak governmental regulation, private sector participation, and corruption. The consequences are urban-centric growth, shortage of qualified faculty, commercialization of postgraduate education, untenable assessment practices, emphasis on rote learning, and inadequate clinical exposure. Recommendations include strengthening accreditation standards and processes possibly by introducing regional or national student assessment, developing defensible student assessment systems, recognizing health profession education as a field of scholarship, and creating a tiered approach to faculty development in education. The relevance of Flexner's recommendations to the current status of medical education in South Asia is striking, in terms of both the progressive nature of his thinking in 1910 and the need to improve medical education in Asia today. In a highly connected world, the improvement of Asian medical education will have a global impact.

    2016-03-01

    In this paper I discuss a contemporary 'take' on the concept of adaptation in light of Crichton-Miller's original 1926 paper. I look briefly at some of the ways that contemporary thinking is both similar to and different from ideas of 90 years ago. In particular I think about how recent neurobiological findings, epigenetic research and attachment theory have cast new light on our understanding of the ways humans adapt to social and emotional environments. It looks at how psychiatric presentations which are seen as maladaptive might well have an adaptive origin in early life. In this account I emphasise how a more modern version of evolutionary theory can be developed, particularly one influenced by life history theory, and suggest that such ideas have powerful explanatory power as well as being based solidly in good research.

  13. Boscovich's philosophical meditations in the history of contemporary thought

    NASA Astrophysics Data System (ADS)

    Gori, P.

    The content of Boscovich's Theoria philosophiae naturalis was well-known to his contemporaries, but both scientists and philosophers chiefly discussed it during the 19th century. The observations that Boscovich presented in this text, and that he himself defined as ``philosophicas metitationes", soon showed their being a good programme for the forthcoming atomic physics, and contributed to get rid of the mechanistic paradigm in science. In this paper I will go back to some meaningful moments of the history of Boscovich's reception in the era of contemporary philosophy, by referring to what authors such as Popper, Cassirer, Nietzsche and Fechner wrote about him. These thinkers, indeed, particularly stressed the importance of the Theoria in the history of Western thought, and showed that it can easily be evaluated beyond the plane of a pure scientific investigation.

  14. Rupturing otherness: becoming Estonian in the context of contemporary Britain.

    PubMed

    Märtsin, Mariann

    2010-03-01

    While identity construction continues to be a widely discussed and researched area in contemporary social sciences, the existing theories have overlooked the importance of understanding why and how identities as semiotic constructions emerge in individuals' consciousness in the flow of their everyday functioning. This article seeks to address this limitation in the theorizing by proposing an alternative conceptualization of identity, according to which identity construction is triggered by rupturing life-experience, which surfaces another perspective and makes the person aware of a possibility to be otherwise or of the reality of being different. Theoretical claims put forward in the paper are drawn from data gathered in a recent study, which explored lived-through experiences of young Estonians, who made study-visits to the United Kingdom. The discussed data will also highlight some interesting aspects in Estonians' self-definition as it is constructed in relation to Eastern-European identity in the context of contemporary Britain.

    In this paper we follow the development and transmission of moral learning from Adam Smith's impartial spectator to Sigmund Freud's superego and then to contemporary psychoanalysis. We argue that defenses are an integral component in the acquisition of any moral system. Elaborating on this argument, we assert that there is a progression from defensive systems that are "closed" to defensive systems that are "open," as defined in a recent work by Novick and Novick. The former system is "static, avoids reality, and is characterized by power dynamics, sadomasochism, and omnipotent defense." The latter, on the other hand, is a system that allows for "joy, creativity, spontaneity, love and it is attuned to reality." Furthermore, while Smith and Freud's systems are more one-person systems of defense, contemporary psychoanalysis has moved to more of a two-person system.

    We investigate the role of deeply-rooted pre-colonial ethnic institutions in shaping comparative regional development within African countries. We combine information on the spatial distribution of ethnicities before colonization with regional variation in contemporary economic performance, as proxied by satellite images of light density at night. We document a strong association between pre-colonial ethnic political centralization and regional development. This pattern is not driven by differences in local geographic features or by other observable ethnic-specific cultural and economic variables. The strong positive association between pre-colonial political complexity and contemporary development obtains also within pairs of adjacent ethnic homelands with different legacies of pre-colonial political institutions.

  19. The ethics of postmortem examinations in contemporary Islam.

    PubMed Central

    Rispler-Chaim, V

    1993-01-01

    Postmortem examinations have recently become common practice in Western medicine: they are used to verify the cause of death and to obtain additional scientific information on certain diseases, as well as to train medical students. For religious people of the monotheistic faiths postmortems present several ethical questions even though the advantages attributed to postmortems in the West are also acknowledged by Jews, Christians and Muslims. The Islamic way of dealing with such questions will be surveyed via contemporary fatawa (legal opinions) issued primarily by Egyptian scholars; Islamic law, which was formulated in the eighth to ninth centuries, did not speak of postmortems. I will therefore depict the means whereby contemporary scholars approach postmortems in the absence of clear legal reference. The difficulties that postmortems create for Muslims at present will be weighed against some shar i instructions which may help circumvent them. While the ethical and religious debate continues, postmortems seem to be accepted but not, however, without certain reservations. PMID:8230149

  20. Contemporary discursive psychology: issues, prospects, and Corcoran's awkward ontology.

    PubMed

    Potter, Jonathan

    2010-12-01

    This paper is both an overview of the status of contemporary discursive psychology and a response to Corcoran's critical article. The first part of the paper reports on the main traditions that make up contemporary discursive psychology and how they relate to one another. Then it responds to Corcoran's claims that much of contemporary discursive psychology: (a) is over concerned with epistemic issues at the expense of ontological issues; (b) is too concerned with data purity while failing reflexively to address its own practices; (c) fails to address ethical, applied, and political issues in the way that a reformed 'ontological' discursive psychology would be able to; (d) fails to provide an adequate and rich account of relationality (of the kind offered by thinkers such as Bakhtin, Shotter, and Chouliaraki). The limitations of each point are addressed in turn, highlighting errors and confusions. The broadly epistemic focus is appropriate for the subject matter of discursive psychology; discursive psychology is less concerned with data purity than with pursuing the radical and empirically progressive possibilities in studying records of people living their lives in everyday and institutional settings (a surprising oversight in a discipline focused on the actions of human beings) and it has a reflexive tradition going back two decades; it has a strong and distinctive focus on ethical, applied, and political issues; it has an account of relationality that is grounded in conversational materials. A single example from interaction on a child protection helpline is analysed to illustrate the way relationality, knowledge, and intersubjectivity have been made analytically tractable in contemporary discursive research.

  5. Organisms as natural purposes: the contemporary evolutionary perspective.

    PubMed

    Walsh, D M

    2006-12-01

    Kant's conception of organisms as natural purposes raises a challenge to the adequacy of mechanistic explanation in biology. Certain features of organisms appear to be inexplicable by appeal to mechanical law alone. Some biological phenomena, it seems, can only be accounted for teleologically. Contemporary evolutionary biology has by and large ignored this challenge. It is widely held that Darwin's theory of natural selection gives us an adequate, wholly mechanical account of the nature of organisms. In contemporary biology, the category of the organism plays virtually no explanatory role. Contemporary evolutionary biology is a science of sub-organismal entities-replicators. I argue that recent advances in developmental biology demonstrate the inadequacy of sub-organismal mechanism. The category of the organism, construed as a 'natural purpose' should play an ineliminable role in explaining ontogenetic development and adaptive evolution. According to Kant the natural purposiveness of organisms cannot be demonstrated to be an objective principle in nature, nor can purposiveness figure in genuine explain. I attempt to argue, by appeal to recent work on self-organization, that the purposiveness of organisms is a natural phenomenon, and, by appeal to the apparatus of invariance explanation, that biological purposiveness provides genuine, ineliminable biological explanations.

    Recent reports suggest that historically typical sexual identity labels-"gay," "lesbian" and "bisexual"-have lost meaning and relevance for contemporary adolescents. Yet there is little empirical evidence that contemporary teenagers are "post-gay." In this brief study we investigate youths' sexual identity labels. The Preventing School Harassment survey included 2,560 California secondary school students administered over 3 years: 2003-2005. We examined adolescents' responses to a closed-ended survey question that asked for self-reports of sexual identity, including an option to write-in a response; we content analyzed the write-in responses. Results suggest that historically typical sexual identity labels are endorsed by the majority (71%) of non-heterosexual youth. Some non-heterosexual youth report that they are "questioning" (13%) their sexual identities or that they are "queer" (5%); a small proportion (9%) provided alternative labels that describe ambivalence or resistance to sexual identity labels, or fluidity in sexual identities. Our results show that lesbian, gay, and bisexual identities remain relevant for contemporary adolescents.

  7. Glacial Isostatic Adjustment and Contemporary Sea Level Rise: An Overview

    NASA Astrophysics Data System (ADS)

    Spada, Giorgio

    2016-08-01

    Glacial isostatic adjustment (GIA) encompasses a suite of geophysical phenomena accompanying the waxing and waning of continental-scale ice sheets. These involve the solid Earth, the oceans and the cryosphere both on short (decade to century) and on long (millennia) timescales. In the framework of contemporary sea-level change, the role of GIA is particular. In fact, among the processes significantly contributing to contemporary sea-level change, GIA is the only one for which deformational, gravitational and rotational effects are simultaneously operating, and for which the rheology of the solid Earth is essential. Here, I review the basic elements of the GIA theory, emphasizing the connections with current sea-level changes observed by tide gauges and altimetry. This purpose is met discussing the nature of the "sea-level equation" (SLE), which represents the basis for modeling the sea-level variations of glacial isostatic origin, also giving access to a full set of geodetic variations associated with GIA. Here, the SLE is employed to characterize the remarkable geographical variability of the GIA-induced sea-level variations, which are often expressed in terms of "fingerprints". Using harmonic analysis, the spatial variability of the GIA fingerprints is compared to that of other components of contemporary sea-level change. In closing, some attention is devoted to the importance of the "GIA corrections" in the context of modern sea-level observations, based on tide gauges or satellite altimeters.

    Clinical growth is an essential component of nursing education, although challenging to evaluate. Considering the paradigm shift toward constructivism and student-centered learning, clinical growth requires an examination within contemporary practices. A concept analysis of clinical growth in nursing education produced defining attributes, antecedents, and consequences. Attributes included higher-level thinking, socialization, skill development, self-reflection, self-investment, interpersonal communication, and linking theory to practice. Identification of critical attributes allows educators to adapt to student-centered learning in the clinical environment. These findings allow educators to determine significant research questions, develop situation-specific theories, and identify strategies to enhance student learning in the clinical environment.

The rapid development of innovative tissue transfer techniques over the past decade provides today's reconstructive urologist with a high probability of achieving excellent long-term outcomes after urethroplasty, even in the reoperative setting. Fundamental principles such as accurate initial stricture staging by urethrography, along with critical assessment of both stricture severity and tissue quality during urethroplasty are critical for success. This review illustrates the way in which stricture length, location, severity, and etiology influences the application of reconstructive techniques during contemporary urethroplasty.

  15. Promoting Science Learning and Scientific Identification through Contemporary Scientific Investigations

    NASA Astrophysics Data System (ADS)

    Van Horne, Katie

    This dissertation investigates the implementation issues and the educational opportunities associated with "taking the practice turn" in science education. This pedagogical shift focuses instructional experiences on engaging students in the epistemic practices of science both to learn the core ideas of the disciplines, as well as to gain an understanding of and personal connection to the scientific enterprise. In Chapter 2, I examine the teacher-researcher co-design collaboration that supported the classroom implementation of a year-long, project-based biology curriculum that was under development. This study explores the dilemmas that arose when teachers implemented a new intervention and how the dilemmas arose and were managed throughout the collaboration of researchers and teachers and between the teachers. In the design-based research of Chapter 3, I demonstrate how students' engagement in epistemic practices in contemporary science investigations supported their conceptual development about genetics. The analysis shows how this involved a complex interaction between the scientific, school and community practices in students' lives and how through varied participation in the practices students come to write about and recognize how contemporary investigations can give them leverage for science-based action outside of the school setting. Finally, Chapter 4 explores the characteristics of learning environments for supporting the development of scientific practice-linked identities. Specific features of the learning environment---access to the intellectual work of the domain, authentic roles and accountability, space to make meaningful contributions in relation to personal interests, and practice-linked identity resources that arose from interactions in the learning setting---supported learners in stabilizing practice-linked science identities through their engagement in contemporary scientific practices. This set of studies shows that providing students with the

The comparison of the vertical fluxes of the particulate matter and the absolute masses of the sediments showed that the contemporary fluxes of sedimentary material to the bottom provided the distribution of the absolute masses of the sediments in the survey area during the Holocene.

It is concluded that apart from the tidewater glacier which is the main source of sediment in this area, the material is transported also from the shores. Subsequently, the material is redeposited by iceberg-caused reworking, slides and gravity flows. Strong decreasing trend of particles' diameters with increasing distance from the ice cliff is observed.

  2. The body complex in contemporary science, literature, and culture

    1998-12-01

    In the simplest terms, the purpose of this dissertation, entitled The Body Complex in Contemporary Science, Literature, and Culture is to examine the relationships between popular quantum mechanics, Chaos Theory (or complex dynamics), and contemporary Feminist/Gender theory. As the title is intended to suggest, this examination is narrowed to the 'event' of the body as it appears within the discourses of several different disciplines. The primary question is, 'what is the body and how do we define it?' And more, how do we conceive of 'a body' at all, from the cosmic to the molecular. How do these very different ideas of body reinforce and/or challenge our own concept of self and the experience of our bodies? And, how is this sense of embodiment represented in popular science, literature, and culture? Finally, the conclusion explores the possibility of liberating practices-complex actions-which may help to reveal the structures of power and alter in some useful ways our own sense of embodiment. This project relies most heavily upon the work of Michel Foucault and other gender critics such as Donna J. Harraway and Judith Butler. However, in support of these arguments a geneology of criticism is established which includes the Renaissance view of the body, a discussion of Karl Marx and materialism, Sigmund Freud and the body as the origin of mind, Lacan's linguistic approach to self-perception, and the theories of the French school of Feminism.

  3. Exploring compassion: implications for contemporary nursing. Part 2.

    PubMed

    Straughair, Collette

    A range of contemporary political and professional literature endorse the principle of compassion in nursing as a core and underpinning philosophy fundamental to the profession. However, despite pledges to ensure that compassion lies at the heart of nursing, the concept has not been clearly defined. It is evident that uncovering the true meaning is complex and challenging owing to its subjective nature. In light of this, several implications must be considered. Effective student nurse recruitment is essential to ensure that the most appropriate individuals are selected. Contemporary marketing campaigns must be implemented, and recruitment strategies developed, which consider specific values and attitudes. Service user involvement in recruitment and selection, curriculum planning and learning and teaching strategies, and post-qualification education, can enhance nurses' understanding of the patient perspective and make headway in embedding compassion as a core nursing value. Additionally, effective role modelling in practice which demonstrates high-quality compassionate nursing care is essential. Nurses must be adequately supported in the clinical environment to facilitate compassionate behaviours and clinical leadership at all levels must uphold political and professional pledges to achieve this. Consideration of these implications for practice is essential to ensure that nurses are able to respond to patients with humanity and kindness, and deliver high-quality, compassionate care to all.

    Subjective feelings of risk are a central feature of everyday life, and evidence shows that people who do not conform to contemporary normative notions are often more exposed to everyday risks than others. Despite this, normative notions are rarely acknowledged as risk objects. By drawing on the theory of 'doing' and 'undoing' risk, which combines intersectional and risk theory, this study contributes new perspectives on the everyday risks in contemporary society that face people who many would label as being 'at risk' - lesbian, gay, bisexual and transgender people. The study consists of five focus group interviews with lesbian, gay, bisexual and transgender people of different ages in Sweden. Findings pinpoint risks and how these are done and un-done in different spheres of interviewees' lives: the emotional risks prevailing in their private lives; the risk of discrimination at work and in relations with other institutions; and the risk of violence and harassment in public places. These risks are all related to the heteronormative order in which the mere fact of being lesbian, gay, bisexual and transgender is perceived as a risk. PMID:26242996

    Gynecologic cancers account for approximately 11% of the newly diagnosed cancers in women in the United States and 18% in the world.1 The most common gynecologic malignancies occur in the uterus and endometrium (53%), ovary (25%), and cervix (14%).2 Cervical cancer is most prevalent in premenopausal women, during their childbearing years, whereas uterine and ovarian cancers tend to present in the perimenopausal or menopausal period. Vaginal and vulvar cancers and malignancies arising from gestation, or gestational trophoblastic neoplasms, occur to a lesser extent. Regardless of cancer origin or age of onset, the disease and its treatment can produce short- and long-term sequelae (ie, sexual dysfunction, infertility, or lymphedema) that adversely affect quality of life (QOL). This article outlines the primary contemporary issues or concerns that may affect QOL and offers strategies to offset or mitigate QOL disruption. These contemporary issues are identified within the domains of sexual functioning, reproductive issues, lymphedema, and the contribution of health-related QOL (HRQOL) in influential gynecologic cancer clinical trials.

    Poleward declines in species diversity [latitudinal diversity gradients (LDG)] remain among the oldest and most widespread of macroecological patterns. However, their contemporary dynamics remain largely unexplored even though changing ecological conditions, including global change, may modify LDG and their respective ecosystems. Here, we examine temporal variation within a temperate Northwest Atlantic LDG using 31 years of annual fisheries-independent surveys and explore its dynamics in relation to a dominant climate signal [the wintertime North Atlantic Oscillation (NAO)] that varies interannually and alters the latitudinal gradient of Northwest Atlantic continental shelf bottom water temperatures. We found that the slopes of the annual LDG vary dramatically due to changes in geographic distributions of 100+ species, variations that are concealed within the cumulative, static LDG. These changes are strongly associated with changes in NAO sign and strength. This is the first illustration of temporal dynamics in a contemporary LDG and the first demonstration of the speed at which local environmental variations can alter an LDG. Our findings underscore the need to investigate factors that modify LDG separately from those that contribute to their origins. PMID:18616548

    Measurements of the 14C content of carbon dioxide in air collected by high-altitude balloon flights in 2003-2005 reveal the contemporary radiocarbon distribution in the northern midlatitude stratosphere, four decades after the Limited Test Ban Treaty restricted atmospheric testing of nuclear weapons. Comparisons with results from a 3-D chemical-transport model show that the 14CO2 distribution is now largely governed by the altitude/latitude dependence of the natural cosmogenic production rate, stratospheric transport, and propagation into the stratosphere of the decreasing radiocarbon trend in tropospheric CO2 due to fossil fuel combustion. From the observed correlation of 14CO2 with N2O mixing ratios, an annual global mean net flux of 14CO2 to the troposphere of 1.6(±0.4) × 1017‰ mol CO2 yr-1 and a global production rate of 2.2(±0.6) × 1026 atoms 14C yr-1 are empirically derived. The results also indicate that contemporary 14CO2 observations provide highly sensitive diagnostics for stratospheric transport and residence times in models.

  9. Implications of Historic River Channel Modifications on Contemporary Restoration Opportunities

    2013-12-01

    Identifying contemporary river management and restoration opportunities relies on understanding how river ecosystems respond to historic forcing from natural events and human impacts. Over the past 70 years, the Big Wood River in central Idaho, USA, has experienced significant engineered channel modifications and realignment, as well as natural changes in channel location and riverbank instability. Understanding the effects of these historic conditions on contemporary river characteristics and processes was needed to inform river management and restoration planning. A geomorphic assessment along 16 km of the Big Wood River was completed in order to understand the physical characteristics and processes upstream, within, and downstream of a 3 km long project reach. This evaluation included analysis of the longitudinal profile, planform pattern, cross-section dimensions, cross-section hydraulics, riverbed and riverbank materials, sediment transport conditions, and large roughness elements such as boulders and large wood material. As a result of residential and highway encroachment along the river corridor, river channel modifications (bank revetments, grade-control drop structures, training channels, sediment traps) have been implemented in attempts to limit the vertical and lateral channel adjustments that would negatively affect infrastructure along the river corridor. These river channel modifications have interrupted the geomorphic processes of the Big Wood River, and have initiated the need for ongoing maintenance of in-channel structures and new efforts at river restoration. Future river ecosystem response along this reach of the Big Wood River will be constrained as a result of river channel and floodplain modifications throughout the valley.

  10. Suffering, meaning, and healing: challenges of contemporary medicine.

    PubMed

    Egnew, Thomas R

    2009-01-01

    This essay explores the thesis that changes in contemporary society have transformed the work of doctoring and challenge doctors to be physician-healers. Medical advances in the prevention and management of acute disease have wrought a growing population of chronically ill patients whose care obliges physicians to become holistic healers. Holistic healing involves the transcendence of suffering. Suffering arises from perceptions of a threat to the integrity of person-hood, relates to the meaning patients ascribe to their illness experience, and is conveyed as an intensely personal narrative. Physician-healers use the power of the doctor-patient relationship to help patients discover or create new illness narratives with fresh meanings that reconnect them to the world and to others and thereby transcend suffering and experience healing. Physician-healers equipped with the attitudes, skills, and knowledge to assist patients to transcend suffering are indispensable if contemporary medicine is to maintain its tradition as a healing profession. In the process, physicians may discover meaningful connections with patients that bring new and refreshing perspectives to their work.

  11. The role of historical and contemporary processes on phylogeographic structure and genetic diversity in the Northern Cardinal, Cardinalis cardinalis

    PubMed Central

    2011-01-01

    Background Earth history events such as climate change are believed to have played a major role in shaping patterns of genetic structure and diversity in species. However, there is a lag between the time of historical events and the collection of present-day samples that are used to infer contemporary population structure. During this lag phase contemporary processes such as dispersal or non-random mating can erase or reinforce population differences generated by historical events. In this study we evaluate the role of both historical and contemporary processes on the phylogeography of a widespread North American songbird, the Northern Cardinal, Cardinalis cardinalis. Results Phylogenetic analysis revealed deep mtDNA structure with six lineages across the species' range. Ecological niche models supported the same geographic breaks revealed by the mtDNA. A paleoecological niche model for the Last Glacial Maximum indicated that cardinals underwent a dramatic range reduction in eastern North America, whereas their ranges were more stable in México. In eastern North America cardinals expanded out of glacial refugia, but we found no signature of decreased genetic diversity in areas colonized after the Last Glacial Maximum. Present-day demographic data suggested that population growth across the expansion cline is positively correlated with latitude. We propose that there was no loss of genetic diversity in areas colonized after the Last Glacial Maximum because recent high-levels of gene flow across the region have homogenized genetic diversity in eastern North America. Conclusion We show that both deep historical events as well as demographic processes that occurred following these events are critical in shaping genetic pattern and diversity in C. cardinalis. The general implication of our results is that patterns of genetic diversity are best understood when information on species history, ecology, and demography are considered simultaneously.

    2008-01-01

    Spontaneous rupture of membranes (ROM) is a normal component of labor and delivery. Premature ROM (PROM) refers to rupture of the fetal membranes prior to the onset of labor irrespective of gestational age. Once the membranes rupture, delivery is recommended when the risk of ascending infection outweighs the risk of prematurity. When PROM occurs at term, labor typically ensues spontaneously or is induced within 12 to 24 hours. The management of pregnancies complicated by preterm PROM (defined as PROM occurring prior to 37 weeks of gestation) is more challenging. Preterm PROM complicates 2% to 20% of all deliveries and is associated with 18% to 20% of perinatal deaths. Management options include admission to hospital, amniocentesis to exclude intra-amniotic infection, and administration of antenatal corticosteroids and broad-spectrum antibiotics, if indicated. This article reviews in detail the contemporary diagnosis and management of preterm PROM. PMID:18701929

    2006-01-01

    Despite the considerable success of contemporary associative models of learning in stimulating new behavioral research and modest success in providing direction to both neuroscience and psychotherapy, these models are confronted with at least three challenges. The first challenge is to the assumption that animals encode only one or a few summary statistics to capture what has been experienced over many training trials. This assumption is contrary to overwhelming evidence that the brain retains episodic information. The second challenge is that the learning-performance distinction has been largely ignored. Most models erroneously assume that behavior is a nearly perfect reflection of what has been encoded. The third challenge is to account for interactions between stimuli that have been presented separately (e.g., stimulus interference) as well as between stimuli that have been presented together (e.g., stimulus competition).

    A contemporary underground coal mine in eastern Kentucky was assessed in order to determine potential off-site and on-site environmental impacts associated with the mining system in the given environmental setting. A 4 section, continuous room and pillor mine plan was developed for an appropriate site in eastern Kentucky. Potential environmental impacts were identified, and mitigation costs determined. The major potential environmental impacts were determined to be: acid water drainage from the mine and refuse site, uneven subsidence of the surface as a result of mining activity, and alteration of ground water aquifers in the subsidence zone. In the specific case examined, the costs of environmental impact mitigation to levels prescribed by regulations would not exceed $1/ton of coal mined, and post mining land values would not be affected.

    Popular music is a key cultural expression that has captured listeners' attention for ages. Many of the structural regularities underlying musical discourse are yet to be discovered and, accordingly, their historical evolution remains formally unknown. Here we unveil a number of patterns and metrics characterizing the generic usage of primary musical facets such as pitch, timbre, and loudness in contemporary western popular music. Many of these patterns and metrics have been consistently stable for a period of more than fifty years. However, we prove important changes or trends related to the restriction of pitch transitions, the homogenization of the timbral palette, and the growing loudness levels. This suggests that our perception of the new would be rooted on these changing characteristics. Hence, an old tune could perfectly sound novel and fashionable, provided that it consisted of common harmonic progressions, changed the instrumentation, and increased the average loudness.

    According to the World Health Organization, globally 4.9 million are blind due to corneal pathology. Corneal transplantation is successful and curative of the blindness for a majority of these cases. However, it is less successful in a number of diseases that produce corneal neovascularization, dry ocular surface and recurrent inflammation, or infections. A keratoprosthesis or KPro is the only alternative to restore vision when corneal graft is a doomed failure. Although a number of KPros have been proposed, only two devices, Boston type-1 KPro and osteo-odonto-KPro, have came to the fore. The former is totally synthetic and the latter is semi-biological in constitution. These two KPros have different surgical techniques and indications. Keratoprosthetic surgery is complex and should only be undertaken in specialized centers, where expertise, multidisciplinary teams, and resources are available. In this article, we briefly discuss some of the prominent historical KPros and contemporary devices. PMID:25945031

    Intracoronary stents have markedly improved the short- and long-term safety and efficacy of percutaneous coronary intervention by improving acute gains in luminal dimensions, decreasing abrupt vessel occlusion, and reducing restenosis. At present, nearly 90% of all coronary interventions involve stenting. A variety of advances in stent technology and design have expanded the clinical application of stenting to include complex coronary lesions, multivessel disease, and small-diameter vessels. In addition, the development of stents as drug delivery systems for antithrombotic or antiproliferative agents has the potential to expand the role of coronary stenting, and early clinical experience appears promising. The purpose of this review is to describe recent developments in stent design, examine the results of clinical trials of contemporary stents, and present future directions for investigation of new stent technologies.

    Bunge's writings on the mind-body problem provide a rigorous, analytical antidote to the persistent anti-materialist tendency that has characterized the history of philosophy and science. Bunge gives special attention to dualism and its shortcomings, and this attention is welcome in view of the resurgence of the doctrine today. However, I focus my comments selectively on Bunge's more controversial, provocative claims, not to dismiss them, but to engage with them seriously. For example, a difficulty arising from Bunge's rhetorical style and its undoubted virtues is that not all the targets of his selfconfessed "bashings" (2010, xi) are equally deserving. For example, Bunge suggests "most contemporary philosophers of mind are indifferent to psychology, or are remarkably uninformed about it". This charge cannot be sustained today in light of the work of foremost philosophers today.

    Cardiac electrophysiologic derangements often coexist with disorders of the circulatory system. Capturing and diagnosing arrhythmias and conduction system disease may lead to a change in diagnosis, clinical management and patient outcomes. Standard 12-lead electrocardiogram (ECG), Holter monitors and event recorders have served as useful diagnostic tools over the last few decades. However, their shortcomings are only recently being addressed by emerging technologies. With advances in device miniaturization and wireless technologies, and changing consumer expectations, wearable “on-body” ECG patch devices have evolved to meet contemporary needs. These devices are unobtrusive and easy to use, leading to increased device wear time and diagnostic yield. While becoming the standard for detecting arrhythmias and conduction system disorders in the outpatient setting where continuous ECG monitoring in the short to medium term (days to weeks) is indicated, these cardiac devices and related digital mobile health technologies are reshaping the clinician-patient interface with important implications for future healthcare delivery.

    The development of critical consciousness (CC) has been theorized to be an essential prerequisite for individual and collective action toward changing inequitable social conditions. However, empirically supported instruments intended to measure this important construct have only recently been introduced to the literature. The purpose of this project was to create a brief, psychometrically sound measure of CC. Two studies with over 600 observations provide initial reliability and validity data on the Contemporary Critical Consciousness Measure (CCCM). Results from exploratory and confirmatory factor analyses suggest that the final 19-item CCCM assesses CC associated with racism, classism, and heterosexism and provides a general index of CC. Results support the internal consistency and factor structure of the measure. Expected relationships between the CCCM and existing measures of symbolic racism, classism, and homonegativity provide evidence for the validity of the instrument. Limitations, future directions for research, and counseling implications are discussed.

    2003-04-01

    In recent decades, social psychologists have suggested that contemporary racism is more subtle in nature than it had been in previous times. However, such theorizing has been from the perspective of the perpetrators. The present study follows a small number of other studies that have focused on the perspective of the victims of racism. It investigated the experiences of racism reported by 34 Aboriginal Australians during semi-structured, open-ended interviews. The data suggest that racism is experienced commonly and frequently by the participants and that much of it is overt or old-fashioned rather than subtle and modern. It is argued that if the data are reflective of what happens in intergroup encounters, social scientists may have embraced the theories of modern racism too readily. This may have contributed to the maintenance of social institutions that impact negatively on the minority populations in the community.

    This paper addresses the linguistic reframing of the human body in contemporary culture. Our aim is to provide a linguistic description of the ways in which the body is represented in modern English language. First, we will try to focus on body metaphors in general. We have collected a sample of 300 words and phrases functioning as body metaphors in modern English language. Reading the symbolism of the body we are witnessing changes in the basic metaphorical structuring of the human body. The results show that new vocabulary binds different fields of knowledge associated with machines and human beings according to a shared textual frame: human as computer and computer as human metaphor. Humans are almost blended with computers and vice versa. This metaphorical use of the human body and its parts reveals not only currents of unconscious though but also the structures of modern society and culture.

    Prior research showed that danwei, the work unit, was very important in determining workers’ social, economic, and political lives in pre-reform urban China. In this paper, we argue that danwei continues to be an agent of social stratification in contemporary urban China. Using data from a 1999 survey we conducted in three large Chinese cities, Wuhan, Shanghai, and Xi’an, we assess the extent to which workers’ socioeconomic well-being depends on the financial conditions of their danwei. Results show that the financial situation of danwei remains one of the most important determinants of earnings and benefits. However, the explanatory power of danwei’s financial situation is much greater for earnings than for benefits. PMID:20191102

    Effective clinical leadership is offered as the key to healthy, functional and supportive work environments for nurses and other health professionals. However, as a concept it lacks a standard definition and is poorly understood. This paper reports on an integrative review undertaken to uncover current understandings of defining attributes of contemporary clinical leadership in nursing. Data collection involved a search of relevant electronic databases for a 10-year period. Keywords for the search were 'clinical leadership' and 'nursing'. Ten research papers met the inclusion criteria for the integrative review. Analysis of these studies indicated clinical leadership attributes had a clinical focus, a follower/team focus or a personal qualities focus; attributes necessary to sustain supportive workplaces and build the capacity and resilience of nursing workforces. The small number of research-based studies yielded for the review indicates the need for further research in the area of clinical leadership. PMID:24099222

    2016-09-15

    Peripheral artery disease (PAD) includes atherosclerosis of the aorta and lower extremities. Affecting a large segment of the population, PAD is associated with impaired functional capacity and reduced quality of life as well as an increased risk of stroke, myocardial infarction and cardiovascular death. The evaluation of PAD begins with the physical examination, incorporating non-invasive testing such as ankle-brachial indices to confirm the diagnosis. Therapeutic interventions are aimed at alleviating symptoms while preserving limb integrity and reducing overall cardiovascular risk. With this in mind, risk factor modification with exercise and medical therapy are the mainstays of treatment for many patients with PAD. Persistent symptoms or non-healing wounds should prompt more aggressive therapies with endovascular or surgical revascularisation. The following manuscript provides a comprehensive review on the contemporary evaluation and management of PAD.

    2014-01-01

    Submarine canyons are morphological incisions into continental margins that act as major conduits of sediment from shallow- to deep-sea regions. However, the exact mechanisms involved in sediment transfer within submarine canyons are still a subject of investigation. Several studies have provided direct information about contemporary sedimentary processes in submarine canyons that suggests different modes of transport and various triggering mechanisms. Storm-induced turbidity currents and enhanced off-shelf advection, hyperpycnal flows and failures of recently deposited fluvial sediments, dense shelf-water cascading, canyon-flank failures, and trawling-induced resuspension largely dominate present-day sediment transfer through canyons. Additionally, internal waves periodically resuspend ephemeral deposits within canyons and contribute to dispersing particles or retaining and accumulating them in specific regions. These transport processes commonly deposit sediments in the upper- and middle-canyon reaches for decades or centuries before being completely or partially flushed farther down-canyon by large sediment failures.

    The activities of German doctors during the Nazi regime are well known and documented. They include efforts at eugenic sterilization and euthanasia, gruesome medical experimentation, and contributions to genocide. The German medical profession embraced the Nazi ideology of racial superiority. Nazi doctors enthusiastically perverted traditional medical mores of viewing each patient as a full individual towards a misguided sense of protecting the racial well-being of the nation from the perceived threat of certain groups of people. Similarly, some 20th-century American physicians engaged in activities prompted by a misguided sense of patients' worth as individuals. This essay will examine the ethical problems of Nazi medicine and ethical missteps in the United States in the context of challenges for contemporary physicians, particularly the way in which we refer to our patients.

    Work in our laboratory has focused on the hypothesis that certain environmental contaminants will interfere with reproductive function because they disrupt the neuroendocrine regulation of gonadal function. In this article, we review the evidence that certain classes of contemporary-use pesticides alter gonadotropin secretion through a disruption of hypothalamic mechanisms. Specifically, we discuss the effect of formamidine and dithiocarbamate pesticides on the noradrenergic control of pituitary hormone secretion, ovarian function, and pregnancy in the rat. This is followed by a review of studies evaluating the effect of a chlorotriazine herbicide, atrazine, on the hormonal control of ovulation and lactation. We also discuss the physiological consequences of these endocrine alterations in the female, how toxicant-induced endocrine alterations may differ in physiological outcome in the male and female, and the fact that the reproductive risk assessment of some pesticides that act on the central nervous system (CNS) may be influenced by the development of tolerance.

    The purpose of this study was to evaluate the abrasive wear and surface roughness of 20 currently available commercial dental composite resins, including nanofilled, supra-nanofilled, nanohybrid and microhybrid composite resins. The volume loss, maximum vertical loss, surface roughness (R(a)) and surface morphology [Scanning electron microscopy (SEM)] were determined after wear. The inorganic filler content was determined by thermogravimetric analysis. The result showed that the volume loss and vertical loss varied among the materials. The coefficients of determination (R(2)) of wear volume loss and filler content (wt%) was 0.283. SEM micrographs revealed nanofilled composites displayed a relatively uniform wear surfaces with nanoclusters protrusion, while the performance of nanohybrid composites varied. The abrasive wear resistance of contemporary dental composite resins is material-dependent and cannot be deduced from its category, filler loading and composite matrix; The abrasive wear resistance of some flowable composites is comparable to the universal/posterior composite resins.

    Immigration into the United States is a particularly salient topic of current contemporary educational, social, and political discussions. The school-related needs of immigrant children and youth can be well served by rigorous research and effective school psychology preservice training and preparation. This overview highlights key definitions, demographic statistics, and current resources related to immigration in U.S. society. This special topic section on understanding immigrants, schooling, and school psychology features articles relevant to this important topic. We conclude with a call for this effort to serve as a springboard for future discussions, scholarship, and school psychology training in preparing practitioners for serving children who are immigrants.

  15. A contemporary theoretical view of ion-atom, -molecule interactions

    Energetic interactions among electrons, ions, atoms, and molecules within gaseous, plasma, and even material environments are fundamental to such diverse phenomena as low temperature plasma processing of semiconductors, collapsing giant molecular clouds forming stars, fluorescent lighting, cold atom condensates, radiation treatment of disease, and the chemistry of earth's atmosphere. Consequently, they have been studied using the contemporary theoretical and computational methods of the time for many years, yet progress continues as we are confronted with challenges presented by new, often more complex systems and by the drive to understand these foundational interactions at an ever more subtle and predictive level. I will illustrate some of this progress using examples from recent work treating very simple systems, for which our knowledge has been both subtly refined and significantly changed, and more complex systems, where complementary methods based on either elaborate treatments or broadly applicable simple models can be used to advance our knowledge.

  16. "Scientific peep show": the human body in contemporary science museums.

    PubMed

    Canadelli, Elena

    2011-01-01

    The essay focuses on the discourse about the human body developed by contemporary science museums with educational and instructive purposes directed at the general public. These museums aim mostly at mediating concepts such as health and prevention. The current scenario is linked with two examples of past museums: the popular anatomical museums which emerged during the 19th century and the health museums thrived between 1910 and 1940. On the museological path about the human body self-care we went from the emotionally involving anatomical Venuses to the inexpressive Transparent Man, from anatomical specimens of ill organs and deformed subjects to the mechanical and electronic models of the healthy body. Today the body is made transparent by the new medical diagnostics and by the latest discoveries of endoscopy. The way museums and science centers presently display the human body involves computers, 3D animation, digital technologies, hands-on models of large size human parts.

  17. Evaluating the Legitimacy of Contemporary Legal Strategies for Obesity.

    Contemporary legal strategies for obesity raise troubling questions regarding individual liberty and the legitimate scope of public health authority. This article argues that the predominant approach to assessing public health legitimacy--John Stuart Mill's "harm principle"--may be unsuitable for evaluating the legitimacy of legal strategies for obesity. The article proposes an alternative test for assessing the legitimate scope of public health authority: John Rawls's liberal principle of legitimacy. It outlines how Rawls's principle would evaluate obesity policies, and contrasts this evaluation to that of Mill. The alternative test avoids some of the limitations of the Millian approach, and may offer an improved mechanism for assessing the liberty effects of policies for obesity and other public health activities.

  19. Contemporary sediment-transport processes in submarine canyons.

    Puig, Pere; Palanques, Albert; Martín, Jacobo

    2014-01-01

    Submarine canyons are morphological incisions into continental margins that act as major conduits of sediment from shallow- to deep-sea regions. However, the exact mechanisms involved in sediment transfer within submarine canyons are still a subject of investigation. Several studies have provided direct information about contemporary sedimentary processes in submarine canyons that suggests different modes of transport and various triggering mechanisms. Storm-induced turbidity currents and enhanced off-shelf advection, hyperpycnal flows and failures of recently deposited fluvial sediments, dense shelf-water cascading, canyon-flank failures, and trawling-induced resuspension largely dominate present-day sediment transfer through canyons. Additionally, internal waves periodically resuspend ephemeral deposits within canyons and contribute to dispersing particles or retaining and accumulating them in specific regions. These transport processes commonly deposit sediments in the upper- and middle-canyon reaches for decades or centuries before being completely or partially flushed farther down-canyon by large sediment failures.

    The new wide-field radio telescopes, such as: ASKAP, MWA, LOFAR, eVLA and SKA; will produce spectral-imaging data-cubes (SIDC) of unprecedented size-in the order of hundreds of Petabytes. Servicing such data as images to the end-user in a traditional manner and formats is likely going to encounter significant performance fallbacks. We discuss the requirements for extremely large SIDCs, and in this light we analyse the applicability of the approach taken in the JPEG2000 (ISO/IEC 15444) standards. We argue the case for the adaptation of contemporary industry standards and technologies versus the modification of legacy astronomy standards or development of new standards specific to astronomy only.

    Hydrologic science has largely built its understanding of the hydrologic cycle using contemporary data sources (i.e., last 100 years). However, as we try to meet water demand over the next 100 years at scales from local to global, we need to expand our scope and embrace other data that address human activities and the alteration of hydrologic systems. For example, the accumulation of human impacts on water systems requires exploration of incompletely documented eras. When examining these historical periods, basic questions relevant to modern systems arise: (1) How is better information incorporated into water management strategies? (2) Does any point in the past (e.g., colonial/pre-European conditions in North America) provide a suitable restoration target? and (3) How can understanding legacies improve our ability to plan for future conditions? Beginning to answer these questions indicates the vital need to incorporate disparate data and less accepted methods to meet looming water management challenges.

    Over the last decades, science has grown increasingly collaborative and interdisciplinary and has come to depart in important ways from the classical analyses of the development of science that were developed by historically inclined philosophers of science half a century ago. In this paper, I shall provide a new account of the structure and development of contemporary science based on analyses of, first, cognitive resources and their relations to domains, and second of the distribution of cognitive resources among collaborators and the epistemic dependence that this distribution implies. On this background I shall describe different ideal types of research activities and analyze how they differ. Finally, analyzing values that drive science towards different kinds of research activities, I shall sketch the main mechanisms underlying the perceived tension between disciplines and interdisciplinarity and argue for a redefinition of accountability and quality control for interdisciplinary and collaborative science.

  3. Authoritative knowledge and birth territories in contemporary Japan.

    PubMed

    Fiedler, D C

    1996-06-01

    In Japan, as in the United States, the change from home to health care institution as the location of birth has been marked by depicting the obstetrician as having authoritative knowledge about birthing. The obstetrician's access to and control over specialized obstetrical technology reflect and legitimate his authoritative status. In Japan a prevailing cultural view of birth as a natural and healthy event places a value on using the least possible amount of obstetrical intervention in the birthing process. This results in the valuation of the potential, rather than the actual, application of obstetrical technology. In contemporary Japan midwives remain integral participants in maternity care and attend normal deliveries in the hospital setting. But because of the culturally depicted potential for pathology at the time of birth, the obstetrician-the birthing specialist who controls the more complex technological tools-is viewed as having greater authoritative knowledge than the midwife and the woman giving birth.

    Popular music is a key cultural expression that has captured listeners' attention for ages. Many of the structural regularities underlying musical discourse are yet to be discovered and, accordingly, their historical evolution remains formally unknown. Here we unveil a number of patterns and metrics characterizing the generic usage of primary musical facets such as pitch, timbre, and loudness in contemporary western popular music. Many of these patterns and metrics have been consistently stable for a period of more than fifty years. However, we prove important changes or trends related to the restriction of pitch transitions, the homogenization of the timbral palette, and the growing loudness levels. This suggests that our perception of the new would be rooted on these changing characteristics. Hence, an old tune could perfectly sound novel and fashionable, provided that it consisted of common harmonic progressions, changed the instrumentation, and increased the average loudness.

    The goal of this work is to learn from nature the rules that govern evolution and the design of protein function. The fundamental laws of physics lie in the foundation of the protein structure and all stages of the protein evolution, determining optimal sizes and shapes at different levels of structural hierarchy. We looked back into the very onset of the protein evolution with a goal to find elementary functions (EFs) that came from the prebiotic world and served as building blocks of the first enzymes. We defined the basic structural and functional units of biochemical reactions—elementary functional loops. The diversity of contemporary enzymes can be described via combinations of a limited number of elementary chemical reactions, many of which are performed by the descendants of primitive prebiotic peptides/proteins. By analyzing protein sequences we were able to identify EFs shared by seemingly unrelated protein superfamilies and folds and to unravel evolutionary relations between them. Binding and metabolic processing of the metal- and nucleotide-containing cofactors and ligands are among the most abundant ancient EFs that became indispensable in many natural enzymes. Highly designable folds provide structural scaffolds for many different biochemical reactions. We show that contemporary proteins are built from a limited number of EFs, making their analysis instrumental for establishing the rules for protein design. Evolutionary studies help us to accumulate the library of essential EFs and to establish intricate relations between different folds and functional superfamilies. Generalized sequence-structure descriptors of the EF will become useful in future design and engineering of desired enzymatic functions.

  7. May 14C be used to date contemporary art?

    The use of radiocarbon in forensics is by now widespread, thanks to the so-called bomb peak, which makes it possible to perform high-precision dating. Since 1955, 14C concentration in the atmosphere had strongly increased due to nuclear explosions, reaching its maximum value in 1963-1965. After the Nuclear Test Ban Treaty, 14C started to decrease as a consequence of the exchanges between atmosphere and the other natural carbon reservoirs. Nowadays, it is still slightly above the pre-bomb value. The work presented in this paper is based on the idea of exploiting the bomb peak to “precisely” date works of contemporary art, with the aim at identifying possible fakes. We analysed two kinds of materials from the 20th century: newspapers and painting canvases. Newspaper samples were taken because they might in principle be considered to represent dated samples (considering the date on the issues). Our data (28 samples) show a trend similar to atmospheric data in the literature, although with some differences; the paper peak is flatter and shifted towards more recent years (about five years) with respect to the atmospheric data. This can be explained by taking paper manufacturing processes into account. As to the canvas samples, the measured 14C concentrations were generally reasonably consistent with the expected concentrations (based on the year on the paintings). However, this does not indicate that the interpretation of the results is simpler and more straightforward. Obviously, we only measure the 14C concentration of the fibre used for the canvas, which does not necessarily measure the date the painting was manufactured. In this paper, sample preparation and experimental results will be discussed, in order to show the potential as well as the limitations of radiocarbon to date contemporary art.

    PCDD/Fs were determined in samples of archived surface soils collected from different locations around the world in the early 1880s, in contemporary surface soils from around the world, in archived subsurface soils collected at Rothamsted Experimental Station in the 1870/1880s, and in sections of peat core deposited between 5000 BP and the present. PCDD/Fs were detected in most of the samples. The potential sources and implications of the levels and mixtures of PCDD/Fs present in the samples are discussed. The homologue and isomer patterns observed in most of the contemporary European surface soils are commonly observed for European air samples and soil samples. The homologue pattern in the Rothamsted surface soils collected in the 1800s was similar, suggesting that similar sources of atmospheric emissions of PCDD/ Fs were operating in the UK in the 1800s as currently. Very different patterns, dominated by OCDD and with contributions of HpCDD and HxCDD, were found in some other samples. It is proposed that the PCDD/Fs present in the subsurface Rothamsted soils, archived (1880s) surface soils from Illinois and the Congo, clay beneath the peat bog (deposited approximately 5000 BP), and possibly surface soil samples from Thailand and Australia are of a natural origin. The most abundant TeCDD/F congeners measured in the peat samples here were also those observed by previous workers who studied a Canadian peat bog and are consistent with the microbially mediated oxidative coupling of chlorophenols. The study provides evidence for the widespread occurrence of PCDD/Fs in the environment prior to 1900 and for a complex array of sources (including natural) and environmental transformation processes.

    Matteliano, Deborah

    2003-01-01

    Nursing is rooted in caring for those who suffer and experience pain. As nursing has grown through the ages, technological advances and socioeconomic changes have required nurses to adapt as they continue to provide holistic, patient-centered care. Over the past century, nursing practice has been dominated by Western medical culture, resulting in a relegation of the caring-healing practices of nurses to the margins of healthcare delivery. Recent changes in the ontology of caring-healing practices are rooted in a new knowledge of complimentary practices. Advancements in behavioral sciences and the neurobiology of pain and suffering, together with an acceptance of Eastern and other healing practices, have enriched and enlightened our understanding of pain management. The recent growth of self-help and support programs has enlightened the healthcare consumer in choosing treatments. Contemporary clinical practice may now include methods that reflect the interconnectedness between the mind and body, such as biofeedback, healing touch, aromatherapy, progressive relaxation, meditation, and behavioral therapy. This article examines the historical concepts of pain and suffering that have influenced the approach to pain management and describes significant holistic methods that may be utilized by the nurse in managing pain.

    With 207 million ha of forest covering 22% of its land area, China ranks fifth in the world in forest area. Rapid economic growth, climate change, and forest disturbances pose new, complex challenges for forest research and management. Progress in meeting these challenges is relevant beyond China, because China's forests represent 34% of Asia's forests and 5% of the worlds' forests. To provide a broader understanding of these management challenges and of research and policies that address them, we organized this special issue on contemporary forest research and management issues in China. At the national level, papers review major forest types and the evolution of sustainable forestry, the development of China's forest-certification efforts, the establishment of a forest inventory system, and achievements and challenges in insect pest control in China. Papers focused on Northern China address historical, social, and political factors that have shaped the region's forests; the use of forest landscape models to assess how forest management can achieve multiple objectives; and analysis and modeling of fuels and fire behavior. Papers addressing Central and South China describe the "Grain for Green" program, which converts low productivity cropland to grassland and woodland to address erosion and soil carbon sequestration; the potential effects of climate change on CO(2) efflux and soil respiration; and relationships between climate and net primary productivity. China shares many forest management and research issues with other countries, but in other cases China's capacity to respond to forest management challenges is unique and bears watching by the rest of the world.

    Background Quaternary climatic oscillations had dramatic effects on species evolution. In northern latitudes, populations had to survive the coldest periods in refugial areas and recurrently colonized northern regions during interglacials. Such a history usually results in a loss of genetic diversity. Populations that did not experience glaciations, in contrast, probably maintained most of their ancestral genetic diversity. These characteristics dramatically affected the present-day distribution of genetic diversity and may influence the ability of species to cope with the current global changes. We conducted a range-wide study of mitochondrial genetic diversity in the pine processionary moth (Thaumetopoea pityocampa/T. wilkinsoni complex, Notodontidae), a forest pest occurring around the Mediterranean Basin and in southern Europe. This species is responding to the current climate change by rapid natural range expansion and can also be accidentally transported by humans. Our aim was to assess if Quaternary climatic oscillations had a different effect across the species' range and to determine if genetic footprints of contemporary processes can be identified in areas of recent introduction. Results We identified three main clades that were spatially structured. In most of Europe, the genetic diversity pattern was typical for species that experienced marked glaciation cycles. Except in refugia, European populations were characterized by the occurrence of one main haplotype and by a strong reduction in genetic diversity, which is expected in regions that were rapidly re-colonized when climatic conditions improved. In contrast, all other sub-clades around the Mediterranean Basin occurred in limited parts of the range and were strongly structured in space, as is expected in regions in which the impact of glaciations was limited. In such places, genetic diversity was retained in most populations, and almost all haplotypes were endemic. This pattern was extreme on remote

    Humoral regulation of somatic and hematopoietic cell growth has been intensely investigated during the past decade. Growth hormone is unique because it regulates the size of the person within the constraints of the genetic program. The somatomedins and insulin growth factors are low molecular weight polypeptides believed to mediate some functions of growth hormone. Epithelial growth factor and nerve growth factor are well-characterized polypeptides that influence the growth and differentiation of epithelial and neural tissues and interact with specific cell surface receptors. The hematopoietins are a family of polypeptide hormones that specifically regulate the proliferation and differentiation of stem cells giving rise to erythrocytes, granulocytes, monocytes, megakaryocytes, and B and T lymphocytes. Platelet-derived growth factor modulates the proliferation of fibroblasts in vitro and may have a role in the development of atherosclerosis and myelofibrosis. New knowledge on the biochemistry and physiology of growth factors will probably have a substantial impact on our understanding of human diseases involving abnormal cell growth.

    Prostate cancer remains among the most commonly diagnosed malignancies worldwide. Early diagnosis and curative treatment appear to improve survival in men with unfavorable-risk cancers, but significant concerns exist regarding the overdiagnosis and overtreatment of men with lower-risk cancers. To this end, active surveillance (AS) has emerged as a primary management strategy in men with favorable-risk disease, and contemporary data suggest that use of AS has increased worldwide. Although published surveillance cohorts differ by protocol, reported rates of metastatic disease and prostate cancer-specific mortality are exceedingly low in the intermediate term (5–10 years). Such outcomes appear to be closely associated with program-specific criteria for selection, monitoring, and intervention, suggesting that AS – like other management strategies – could be individualized based on the level of risk acceptable to patients in light of personal preferences. Additional data are needed to better establish the risks associated with AS and to identify patient-specific characteristics that could modify prognosis. PMID:26954332

    In the last several hundred years agriculture has caused significant human induced Land Cover Land Use Change (LCLUC) with dramatic cropland expansion and a marked increase in agricultural productivity. The size of agricultural fields is a fundamental description of rural landscapes and provides an insight into the drivers of rural LCLUC. Increasing field sizes cause a subsequent decrease in the number of fields and therefore decreased landscape spatial complexity with impacts on biodiversity, habitat, soil erosion, plant-pollinator interactions, diffusion of disease pathogens and pests, and loss or degradation in buffers to nutrient, herbicide and pesticide flows. In this study, globally distributed locations with significant contemporary field size change were selected guided by a global map of agricultural yield and literature review and were selected to be representative of different driving forces of field size change (associated with technological innovation, socio-economic conditions, government policy, historic patterns of land cover land use, and environmental setting). Seasonal Landsat data acquired on a decadal basis (for 1980, 1990, 2000 and 2010) were used to extract field boundaries and the temporal changes in field size quantified and their causes discussed.

  11. Change Ringing - communicating climate change through contemporary classical music

    Change Ringing is a collaborative artwork by artist Peter Shenai and composer Laurence Osborn that forms around a playable sculpture and a large-scale composition. The sculpture incorporates a set of six bronze bells designed and cast by artist Peter Shenai. Their shapes are mathematically derived from graphic statistical representations of summer temperatures at seventeen-year intervals over the course of the twentieth century. Arranged according to the chronology of their corresponding data sets and struck in order, the bells voice a series of inharmonic spectra that communicate sonically the story of climate change during the twentieth century. This series forms the basis for Laurence Osborn's twenty-five minute composition, scored for string orchestra and the bells themselves. In Change Ringing, an artwork that combines music, sculpture, performance, and ritual, we want to move audiences and, in doing so, facilitate their engagement with ideas that are highly relevant today. We believe that the medium of musically organized sound, so often wrongly dismissed as "abstract" and non-referential, can be a more than adequate reflection of lived human experience in the 21st Century, and we work in the hope that Change Ringing will connect with contemporary audiences on the most fundamental level.

  12. Organisational and educational internal impediments of psychoanalysis: contemporary challenges.

    2002-12-01

    Our psychoanalytic discipline originated, has evolved and is still located within a congregational network that blends and binds together, in an inextricable and contradictory way, the missionary mandates and commendations of a 'movement' and a 'cause' with the inherent prerogatives and functions of academic professions and sciences. In this paper the author explores the consequential past and present impedimenta of this organisational and educational syncretism, for six fundamental dimensions of action for psychoanalysis. Subsequently, the nature of a proposition is delineated, suggesting a reorganisation, local and international, to address what the author visualises as five of our most pressing contemporary challenges: a) an autonomous university educational model, freed from regressive societal-political inertias, enabling us to abandon our seclusive monasticism; b) the consolidation of an epistemological frame of reference, idiographic and nomothetically substantiated against our cumulative inductivism, which is the seedbed of our sectarianism, cross-sterilisation and pseudo-ecumenism; c) local and external educational and professional systems of accreditation and certification, independent from affiliation and membership privileges of our supraordinate ecclesia; d) social relevance and community presence, moving away from our meaningless organisational and educational cloistering; and e) a local and international functional and interdependent reorganisation, in the context of sovereignty and integrity, in contrast to our prevalently crusading and indoctrinating homogamous pathological co-dependency. The author concludes that only a harmonisation of objectives and administrative structure might loosen the talons of faith that keep us retrogressively tied to our past.

    As society ages and frequency of dementia increases exponentially, counteracting cognitive aging decline is a challenging issue for countries of the developed world. Previous studies have suggested that physical fitness based on cardiovascular and strength training helps to improve attentional control in normal aging. However, how motor activity based on motor-skill learning can also benefit attentional control with age has been hitherto a neglected issue. This study examined the impact of contemporary dance (CD) improvisation on attentional control of older adults, as compared to two other motor training programs, fall prevention and Tai Chi Chuan. Participants performed setting, suppressing, and switching attention tasks before and after 5.7-month training in either CD or fall prevention or Tai Chi Chuan. Results indicated that CD improved switching but not setting or suppressing attention. In contrast, neither fall prevention nor Tai Chi Chuan showed any effect. We suggest that CD improvisation works as a training for change, inducing plasticity in flexible attention. PMID:21960971

  14. Remapping worker citizenship in contemporary occupational health and safety regimes.

    2007-01-01

    The article draws on the rapidly growing field of citizenship studies to map and explore the dynamics of contemporary occupational health and safety (OHS) regulation. Using two key dimensions of OHS regulation (protection and participation), the author constructs four ideal types of worker citizenship (market, public, private industrial, and public industrial citizens). Historically, workers have been written into OHS regulatory regimes in each of these ways. Most recently lawmakers have created a new species of OHS regimes, best described as mandated partial self-regulation. Its distinguishing characteristic is its flexibility, such that worker citizenship can take on any of the forms previously described, often without changing the statutory framework. Using Ontario as an example, the study finds that in the late 20th century, workers made significant strides toward public industrial citizenship and, surprisingly, even under a neoconservative government, workers successfully defended their participatory rights and saw their right to protection modestly strengthened through increased enforcement. The conditions under which this regime operates, however, constantly threaten to undermine the efficacy of worker participation rights and to weaken the enforcement effort. Some suggestions are made about using a citizenship discourse to revitalize the worker OHS movement and strengthen OHS rights.

This work belongs to the Contemporary Art Museum of the University of São Paulo (MAC-USP) and such coating modified the artwork characteristics, causing an unpleasant effect and compromising its exhibition. The choice of the proper conservation and restoration strategies involves the understanding of the degradation process, demanding the identification of the chemical compounds formed on the painting surface, as well as of the other components in the painting. The results here obtained from Raman and optical microscopies, FTIR-ATR, SEM-EDS and GC-MS, revealed that the efflorescence chemical composition is almost only palmitic acid, with minor contents of stearic acid and their methyl esters, and that the paints are composed by chrome yellow, amorphous carbon and toluidine red pigment; an aluminum silicate filler in the black paint applied on the aluminum ground was also detected. Hierarchical Cluster Analyses (HCA) of the Raman spectra also revealed that the concentration of the efflorescence minor components depends on the paint composition. It was suggested, therefore, that the degradation process resulted from segregation and migration of mainly palmitic acid from the dried paints. Restoration methodologies used in similar cases, as well as factors that contribute to this process, were discussed. PMID:26836452

    Results are reported for detailed sterol analyses of several depths (corresponding to between zero and about 150 yr in age) in a contemporary lacustrine sediment from a freshwater lake of postglacial origin in England. Delta 5-, delta 22-, and delta 5,22-sterols are identified along with 5 alpha- and 5 beta-stanols as well as a C26 stanol with a C7 side chain. Solvent extraction yields carbon number distributions for the 5 alpha- and 5 beta-stanol sediment constituents that parallel the corresponding delta 5-sterol distributions. The amounts of 5 alpha-stanols are found to exceed those of 5 beta-stanols in the sediment, and variations in the ratio of 5 alpha- to 5 beta-stanol between sediment samples from similar depths are shown to suggest an inhomogeneity of the sediment. It is found that the sterol composition of sediment cores varies markedly with depth, reflecting both the effects of a sterol hydrogenation process and a changing input to the sediment. It is concluded that C29 sterols, of probable higher-plant origin, predominate at lower sediment depths while C27 sterols, possibly derived from autochthonous sources, are more abundant in the surface sediment.

    The mechanisms shaping island biotas are not yet well understood mostly because of a lack of studies comparing eco-evolutionary fingerprints over entire taxonomic groups. Here, we linked community structure (richness, frequency and nestedness) and genetic differentiation (based on mitochondrial DNA) in order to compare insular butterfly communities occurring over a key intercontinental area in the Mediterranean (Italy-Sicily-Maghreb). We found that community characteristics and genetic structure were influenced by a combination of contemporary and historical factors, and among the latter, connection during the Pleistocene had an important impact. We showed that species can be divided into two groups with radically different properties: widespread taxa had high dispersal capacity, a nested pattern of occurrence, and displayed little genetic structure, while rare species were mainly characterized by low dispersal, high turnover and genetically differentiated populations. These results offer an unprecedented view of the distinctive butterfly communities and of the main processes determining them on each studied island and highlight the importance of assessing the phylogeographic value of populations for conservation.

    Global population increases, coupled with intensive animal and livestock production practices, have resulted in the generation, accumulation, and disposal of large amounts of wastes around the world. Aerosolization of microbial pathogens, endotoxins, odors, and dust particles is an inevitable consequence of the generation and handling of waste material. Bioaerosols can be a source of microbial pathogens, endotoxins, and other allergens. Given the close proximity of population centers to concentrated animal-rearing operations and municipal treatment facilities in many parts of the world, there is concern regarding the occupational and public health impacts associated with the exposure to bioaerosols from municipal and animal wastes. Major advances have been made in our understanding of bioaerosol characteristics, identifying the hazards, and identifying possible human and animal health links with aerosolized pathogens and allergens. However, significant knowledge and technology gaps still exist. These include a lack of clear understanding of the fate and transport of bioaerosols, especially within the open environment, an inability to accurately predict the health risks associated with bioaerosolized pathogens, and a lack of standardized bioaerosol sampling protocols, and efficient samplers. This review synthesizes the information related to bioaerosols and addresses the contemporary issues associated with bioaerosols from municipal and animal wastes, with a focus on pathogens.

    A country-level stock and flow model for cement, an important construction material, was developed based on a material flow analysis framework. Using this model, the contemporary cement cycle of the United States was constructed by analyzing production, import, and export data for different stages of the cement cycle. The United States currently supplies approximately 80% of its cement consumption through domestic production and the rest is imported. The average annual net addition of in-use new cement stock over the period 2000-2004 was approximately 83 million metric tons and amounts to 2.3 tons per capita of concrete. Nonfuel carbon dioxide emissions (42 million metric tons per year) from the calcination phase of cement manufacture account for 62% of the total 68 million tons per year of cement production residues. The end-of-life cement discards are estimated to be 33 million metric tons per year, of which between 30% and 80% is recycled. A significant portion of the infrastructure in the United States is reaching the end of its useful life and will need to be replaced or rehabilitated; this could require far more cement than might be expected from economic forecasts of demand for cement. ?? 2009 Springer Japan.

  3. Vicarious learning revisited: a contemporary behavior analytic interpretation.

    1997-03-01

    Beginning in the 1960s, social learning theorists argued that behavioral learning principles could not account for behavior acquired through observation. Such a viewpoint is still widely held today. This rejection of behavioral principles in explaining vicarious learning was based on three phenomena: (1) imitation that occurred without direct reinforcement of the observer's behavior; (2) imitation that occurred after a long delay following modeling; and (3) a greater probability of imitation of the model's reinforced behavior than of the model's nonreinforced or punished behavior. These observations convinced social learning theorists that cognitive variables were required to explain behavior. Such a viewpoint has progressed aggressively, as evidenced by the change in name from social learning theory to social cognitive theory, and has been accompanied by the inclusion of information-processing theory. Many criticisms of operant theory, however, have ignored the full range of behavioral concepts and principles that have been derived to account for complex behavior. This paper will discuss some problems with the social learning theory explanation of vicarious learning and provide an interpretation of vicarious learning from a contemporary behavior analytic viewpoint.

    The discipline of studying medication errors and implementing medication safety programs in hospitals dates to the 1970s. These initial programs to prevent errors focused only on pharmacy operation changes - and not the broad medication use system. In the late 1990s, research showed that faulty systems, and not faulty people, are responsible for errors and require a multidisciplinary approach. The 2013 ASHP Statement on the Role of the Medication Safety Leader recommended that medication safety leaders be integrated team members rather than a single point of contact. Successful medication safety programs must employ a new approach - one that embraces the skills of all health care team members and positions many leaders to improve safety. This approach requires a new set of leadership skills based on contemporary management principles, including followership, team-building, tracking and assessing progress, storytelling and communication, and cultivating innovation, all of which promote transformational change. The application of these skills in developing or changing a medication safety program is reviewed in this article.

    The neuronal processes underlying dance observation have been the focus of an increasing number of brain imaging studies over the past decade. However, the existing literature mainly dealt with effects of motor and visual expertise, whereas the neural and cognitive mechanisms that underlie the interpretation of dance choreographies remained unexplored. Hence, much attention has been given to the action observation network (AON) whereas the role of other potentially relevant neuro-cognitive mechanisms such as mentalizing (theory of mind) or language (narrative comprehension) in dance understanding is yet to be elucidated. We report the results of an fMRI study where the structural coherence of short contemporary dance choreographies was manipulated parametrically using the same taped movement material. Our participants were all trained dancers. The whole-brain analysis argues that the interpretation of structurally coherent dance phrases involves a subpart (superior parietal) of the AON as well as mentalizing regions in the dorsomedial prefrontal cortex. An ROI analysis based on a similar study using linguistic materials (Pallier et al., 2011) suggests that structural processing in language and dance might share certain neural mechanisms.

    This article engages with the philosophical reflections of the French historian of science Hélène Metzger (1886–1944) in order to develop a vocabulary for understanding the rise of non-reductive Continental naturalism in the contemporary humanities. The bibliography of current naturalist approaches in the arts and the human sciences is still in the making, but it is altogether clear that the trend is not scientist or historicist or relativist. This epistemological diagnosis refers us to Metzger, who found herself surrounded with the logical positivism of the Wiener Kreis, on the one hand, and the historicism of her French colleagues, on the other, as well as with the infiltration of the history of science by a chronological empiricism. In this article I will take the most recent book of Vicki Kirby – Quantum Anthropologies: Life at Large from 2011 – as an exemplary case of non-reductive Continental naturalist scholarship in the humanities today and by reading it through the concepts of Metzger, I will demonstrate how this type of research leads to refreshing insights in what constitutes positive humanities knowledge and what is the role of the a priori in the field.

    Objective To describe contemporary cesarean delivery practice in the U.S. Study Design Consortium on Safe Labor collected detailed labor and delivery information from 228,668 electronic medical records from 19 hospitals across the U.S., 2002 – 2008. Results The overall cesarean delivery rate was 30.5%. 31.2% of nulliparas were delivered by cesarean section. Prelabor repeat cesarean delivery due to a previous uterine scar contributed 30.9% of all cesarean sections. 28.8% of women with a uterine scar had a trial of labor and the success rate was 57.1%. 43.8% women attempting vaginal delivery had induction. Half of cesarean for dystocia in induced labor were performed before 6 cm of cervical dilation. Conclusion To decrease cesarean delivery rate in the U.S., reducing primary cesarean delivery is the key. Increasing VBAC rate is urgently needed. Cesarean section for dystocia should be avoided before the active phase is established, particularly in nulliparas and in induced labor. PMID:20708166

    The fraction of naturally produced bis (2-ethylhexyl) phthalate (DEHP), a ubiquitous plasticizer known to contaminate packaged foods, was determined for each of five 1.10 kg samples of unsalted market butter by accelerator mass spectrometry (AMS). After extraction and concentration enrichment with liquid-liquid extraction, flash column chromatography, and preparative-scale high performance liquid chromatography, each sample provided ≈ 250 μg extracts of DEHP with carbon purity ranging from 92.5 ± 1.2% (n = 3, 1σ) to 97.1 ± 0.8% (n = 3, 1σ) as measured with gas chromatography mass spectrometry (GC-MS). After corrections for method blank DEHP, co-eluting compounds, and unidentified carbon, the mean fraction of naturally produced DEHP in butter was determined to be 0.16 ± 0.12 (n = 5, 1σ). To our knowledge, this is the first report of the contemporary fraction of DEHP isolated from market butter in the U.S.

    Because health care professions exist to provide a good for society, ethical questions are inherently part of them. Such professions and their members can be assessed based on how effective they are in developing knowledge and enacting practices that further the health and well-being of individuals and society. The complexity of contemporary health care environments makes it important to prepare clinicians who can anticipate, recognize, and address problems that arise in practice or that prevent a profession from fulfilling its service goals and obligations. Different health care professions have evolved distinct perspectives about appropriate goals for, and the purposes of, their clinicians, even when the goal of improving health and well-being for society is shared across professions. While medicine and nursing goals are shared in principle, they differ in the particulars. Given the centrality to nursing of ethical questions, the profession has a collective responsibility to help clinicians at all levels of practice become ethically savvy and to reinforce their moral agency as needed. Both knowledge of nursing ethics and knowledge of the interdisciplinary field of bioethics are critical to nursing work. PMID:27649912

    A whitish crystalline-like coating was observed on the surface of the painting "Incêndio", 1990, produced by Emmanuel Nassar and awarded at the 6th Biennial of Cuenca. This work belongs to the Contemporary Art Museum of the University of São Paulo (MAC-USP) and such coating modified the artwork characteristics, causing an unpleasant effect and compromising its exhibition. The choice of the proper conservation and restoration strategies involves the understanding of the degradation process, demanding the identification of the chemical compounds formed on the painting surface, as well as of the other components in the painting. The results here obtained from Raman and optical microscopies, FTIR-ATR, SEM-EDS and GC-MS, revealed that the efflorescence chemical composition is almost only palmitic acid, with minor contents of stearic acid and their methyl esters, and that the paints are composed by chrome yellow, amorphous carbon and toluidine red pigment; an aluminum silicate filler in the black paint applied on the aluminum ground was also detected. Hierarchical Cluster Analyses (HCA) of the Raman spectra also revealed that the concentration of the efflorescence minor components depends on the paint composition. It was suggested, therefore, that the degradation process resulted from segregation and migration of mainly palmitic acid from the dried paints. Restoration methodologies used in similar cases, as well as factors that contribute to this process, were discussed.

    Because autosomal genes in sexually reproducing organisms spend on average half their time in each sex, and because the traits that they influence encounter different selection pressures in males and females, the evolutionary responses of one sex are constrained by processes occurring in the other sex. Although intralocus sexual conflict can restrict sexes from reaching their phenotypic optima, no direct evidence currently supports its operation in humans. Here, we show that the pattern of multivariate selection acting on human height, weight, blood pressure and glucose, total cholesterol, and age at first birth differs significantly between males and females, and that the angles between male and female linear (77.8 ± 20.5°) and nonlinear (99.1 ± 25.9°) selection gradients were closer to orthogonal than zero, confirming the presence of sexually antagonistic selection. We also found evidence for intralocus sexual conflict demonstrated by significant changes in the predicted male and female responses to selection of individual traits when cross-sex genetic covariances were included and a significant reduction in the angle between male- and female-predicted responses when cross-sex covariances were included (16.9 ± 15.7°), compared with when they were excluded (87.9 ± 31.6°). We conclude that intralocus sexual conflict constrains the joint evolutionary responses of the two sexes in a contemporary human population. PMID:23034705

  14. Contemporary therapy: aromatherapy in the management of acute pain?

    PubMed

    Ching, M

    1999-12-01

    Recent surveys indicate that people are increasingly using complementary therapies as an adjunct or alternative to conventional treatment options as well as for general health and well being. Whilst complementary therapies such as aromatherapy have been utilised in clinical settings as diverse as long term care facilities and palliative care, its application to the acute care setting has not been explored in depth. The changes in contemporary health care practices such as post-operative pain management and length of hospital admissions have provided nurses with the challenge of examining the range of therapeutic interventions that can be applied to their practice. The purpose of this paper is to examine critically the potential uses of aromatherapy in the management of acute post-operative pain. The concept of aromatherapy will be explored in relation to its effects on the pain pathways, methods of administration and therapeutic effects. Specific reference will be made to Lavender (Lavandula angustifolia) and its use in aromatherapy. A review of the literature points to gaps in the knowledge related to the clinical application of aromatherapy in relation to issues of dosage, methods of administration and therapeutic effects. The relatively small number of studies that have looked at aromatherapy in the acute care setting supports the literature reviewed. Issues such as small sample sizes and the difficulty in replicating these studies make it difficult to generalize the findings. In order to achieve best practice, further research is necessary to explore the use of aromatherapy in the management of acute post-operative pain.

    Background Paper mulberry has been used for thousands of years in Asia and Oceania for making paper and bark-cloth, respectively. Museums around the world hold valuable collections of Polynesian bark-cloth. Genetic analysis of the plant fibers from which the textiles were made may answer a number of questions of interest related to provenance, authenticity or species used in the manufacture of these textiles. Recovery of nucleic acids from paper mulberry bark-cloth has not been reported before. Methodology We describe a simple method for the extraction of PCR-amplifiable DNA from small samples of contemporary Polynesian bark-cloth (tapa) using two types of nuclear markers. We report the amplification of about 300 bp sequences of the ITS1 region and of a microsatellite marker. Conclusions Sufficient DNA was retrieved from all bark-cloth samples to permit successful PCR amplification. This method shows a means of obtaining useful genetic information from modern bark-cloth samples and opens perspectives for the analyses of small fragments derived from ethnographic materials.

  16. Contemporary models of change in the health professions.

    1996-01-01

    This article reviews the special position that health professionals have occupied and the ways in which changes threaten the foundations of professional work. The application of modern management principles to health care runs the risk of overriding the "action orientation" that is a defining component of professional work. One goal of health workforce design should be the engineering of opportunities for the preservation of "professional voice" as a countervailing force to ensure high quality health care. Contemporary models of change applied to health care workforce include: (1) the system of professions models in which securing and maintaining jurisdiction are the mechanisms that professions employ to sustain their position, (2) a strategic adaptation model by which professions attempt to adjust to changing environments, (3) a model of redesigning patient care which applies Total Quality Management (TQM) and other "industrial techniques" to the health care workplace, and, (4) model of "consumer sovereignty" in which groups of citizens come together to determine the nature of care services and professional work, with the participation of the organizations and providers.

    Fine particulate matter collected at two urban, four near-urban, and six remote sites throughout the United States were analyzed for total carbon (TC) and radiocarbon ({sup 14}C). Samples were collected at most sites for both a summer and winter season. The radiocarbon was used to partition the TC into fossil and contemporary fractions. On average, contemporary carbon composed about half of the carbon at the urban, {approx}70-97% at near-urban, and 82-100% at remote sites. At Phoenix, Arizona, and Seattle, Washington, one monitor was located within the urban center and one outside to assess the urban excess over background concentrations. During the summer the urban and rural sites had similar contemporary carbon concentrations. However, during the winter the urban sites had more than twice the contemporary carbon measured at the neighboring sites, indicating anthropogenic contributions to the contemporary carbon. The urban fossil carbon was 4-20 times larger than the neighboring rural sites for both seasons. Organic (OC) and elemental carbon (EC) from TOR analysis were available. These and the radiocarbon data were used to estimate characteristic fossil and contemporary EC/TC ratios for the winter and summer seasons. These ratios were applied to carbon data from the Interagency Monitoring of Protected Visual Environments network to estimate the fraction of contemporary carbon at mostly rural sites throughout the United States. In addition, the ratios were used to develop a semiquantitative, lower bound estimate of secondary organic carbon (SOC) contribution to fossil and contemporary carbon. SOC accounted for more than one-third of the fossil and contemporary carbon.

  18. Extrapituitary growth hormone and growth?

    2014-09-01

    While growth hormone (GH) is obligatory for postnatal growth, it is not required for a number of growth-without-GH syndromes, such as early embryonic or fetal growth. Instead, these syndromes are thought to be dependent upon local growth factors, rather than pituitary GH. The GH gene is, however, also expressed in many extrapituitary tissues, particularly during early development and extrapituitary GH may be one of the local growth factors responsible for embryonic or fetal growth. Moreover, as the expression of the GH receptor (GHR) gene mirrors that of GH in extrapituitary tissues the actions of GH in early development are likely to be mediated by local autocrine or paracrine mechanisms, especially as extrapituitary GH expression occurs prior to the ontogeny of pituitary somatotrophs or the appearance of GH in the circulation. The extrapituitary expression of pituitary somatotrophs or the appearance of GH in the circulation. The extrapituitary expression of GH in embryos has also been shown to be of functional relevance in a number of species, since the immunoneutralization of endogenous GH or the blockade of GH production is accompanied by growth impairment or cellular apoptosis. The extrapituitary expression of the GH gene also persists in some central and peripheral tissues postnatally, which may reflect its continued functional importance and physiological or pathophysiological significance. The expression and functional relevance of extrapituitary GH, particularly during embryonic growth, is the focus of this brief review.

    Understanding the human aging of postural control and how physical or motor activity improves balance and gait is challenging for both clinicians and researchers. Previous studies have evidenced that physical and sporting activity focusing on cardiovascular and strength conditioning help older adults develop their balance and gait and/or decrease their frequency of falls. Motor activity based on motor-skill learning has also been put forward as an alternative to develop balance and/or prevent falls in aging. Specifically dance has been advocated as a promising program to boost motor control. In this study, we examined the effects of contemporary dance (CD) on postural control of older adults. Upright stance posturography was performed in 38 participants aged 54–89 years before and after the intervention period, during which one half of the randomly assigned participants was trained to CD and the other half was not trained at all (no dance, ND). CD training lasted 4 weeks, 3 times a week. We performed classical statistic scores of postural signal and dynamic analyses, namely signal diffusion analysis (SDA), recurrence quantification analysis (RQA), and detrended fluctuation analysis (DFA). CD modulated postural control in older trainees, as revealed in the eyes closed condition by a decrease in fractal dimension and an increase in DFA alpha component in the mediolateral plane. The ND group showed an increase in length and mean velocity of postural signal, and the eyes open a decrease in RQA maximal diagonal line in the anteroposterior plane and an increase in DFA alpha component in the mediolateral plane. No change was found in SDA in either group. We suggest that such a massed practice of CD reduced the quantity of exchange between the subject and the environment by increasing their postural confidence. Since CD has low-physical but high-motor impact, we conclude that it may be recommended as a useful program to rehabilitate posture in aging. PMID:24611047

    O'Mathúna, Dónal P

    2006-01-01

    Background The justification for Nazi programs involving involuntary euthanasia, forced sterilisation, eugenics and human experimentation were strongly influenced by views about human dignity. The historical development of these views should be examined today because discussions of human worth and value are integral to medical ethics and bioethics. We should learn lessons from how human dignity came to be so distorted to avoid repetition of similar distortions. Discussion Social Darwinism was foremost amongst the philosophies impacting views of human dignity in the decades leading up to Nazi power in Germany. Charles Darwin's evolutionary theory was quickly applied to human beings and social structure. The term 'survival of the fittest' was coined and seen to be applicable to humans. Belief in the inherent dignity of all humans was rejected by social Darwinists. Influential authors of the day proclaimed that an individual's worth and value were to be determined functionally and materialistically. The popularity of such views ideologically prepared German doctors and nurses to accept Nazi social policies promoting survival of only the fittest humans. A historical survey reveals five general presuppositions that strongly impacted medical ethics in the Nazi era. These same five beliefs are being promoted in different ways in contemporary bioethical discourse. Ethical controversies surrounding human embryos revolve around determinations of their moral status. Economic pressures force individuals and societies to examine whether some people's lives are no longer worth living. Human dignity is again being seen as a relative trait found in certain humans, not something inherent. These views strongly impact what is taken to be acceptable within medical ethics. Summary Five beliefs central to social Darwinism will be examined in light of their influence on current discussions in medical ethics and bioethics. Acceptance of these during the Nazi era proved destructive to many

    To explore contemporary (from 1990) utilization and practice of electroconvulsive therapy (ECT) worldwide. Systematic search (limited to studies published 1990 and after) was undertaken in the databases Medline, Embase, PsycINFO, SveMed, and EBSCO/Cinahl. Primary data-based studies/surveys with reported ECT utilization and practice in psychiatric institutions internationally, nationally, and regionally; city were included. Two reviewers independently checked study titles and abstracts according to inclusion criteria, and extracted ECT utilization and practice data from those retrieved in full text. Seventy studies were included, seven from Australia and New Zealand, three Africa, 12 North and Latin America, 33 Europe, and 15 Asia. Worldwide ECT differences and trends were evident, average number ECTs administered per patient were eight; unmodified (without anesthesia) was used in Asia (over 90%), Africa, Latin America, Russia, Turkey, Spain. Worldwide preferred electrode placement was bilateral, except unilateral at some places (Europe and Australia/New Zealand). Although mainstream was brief-pulse wave, sine-wave devices were still used. Majority ECT treated were older women with depression in Western countries, versus younger men with schizophrenia in Asian countries. ECT under involuntary conditions (admissions), use of ambulatory-ECT, acute first line of treatment, as well as administered by other professions (geriatricians, nurses) were noted by some sites. General trends were only some institutions within the same country providing ECT, training inadequate, and guidelines not followed. Mandatory reporting and overall country ECT register data were sparse. Many patients are still treated with unmodified ECT today. Large global variation in ECT utilization, administration, and practice advocates a need for worldwide sharing of knowledge about ECT, reflection, and learning from each other's experiences.

    2007-01-01

    The Council on Aviation Accreditation (CAA) was established in 1988 in response to the need for formal, specialized accreditation of aviation academic programs, as expressed by institutional members of the University Aviation Association (UAA). The first aviation programs were accredited by the CAA in 1992, and today, the CAA lists 60 accredited programs at 21 institutions nationwide. Although the number of accredited programs has steadily grown, there are currently only 20 percent of UAA member institutions with CAA accredited programs. In an effort to further understand this issue, a case study of the CAA was performed, which resulted in a two-part case study report. Part one addressed the historical foundation of the organization and the current environment in which the CAA functions. Part two focuses on the following questions: (a) what are some of the costs to a program seeking CAA accreditation (b) what are some fo the benefits of being CAA accredited; (c) why do programs seek CAA accreditation; (d) why do programs choose no to seek CAA accreditation; (e) what role is the CAA playing in the international aviation academic community; and (f) what are some possible strategies the CAA may adopt to enhance the benefits of CAA accreditation and increase the number of CAA accredited programs. This second part allows for a more thorough understanding of the contemporary issued faced by the organization, as well as alternative strategies for the CAA to consider in an effort to increase the number of CAA accredited programs and more fully fulfill the role of the CAA in the collegiate aviation community.

    In recent decades the rate and geographic extent of land-use and land-cover change has increased throughout the world's humid tropical forests. The pan-tropical geography of forest change is a challenge to assess, and improved estimates of the human footprint in the tropics are critical to understanding potential changes in biodiversity. We combined recently published and new satellite observations, along with images from Google Earth and a literature review, to estimate the contemporary global extent of deforestation, selective logging, and secondary regrowth in humid tropical forests. Roughly 1.4% of the biome was deforested between 2000 and 2005. As of 2005, about half of the humid tropical forest biome contained 50% or less tree cover. Although not directly comparable to deforestation, geographic estimates of selective logging indicate that at least 20% of the humid tropical forest biome was undergoing some level of timber harvesting between 2000 and 2005. Forest recovery estimates are even less certain, but a compilation of available reports suggests that at least 1.2% of the humid tropical forest biome was in some stage of long-term secondary regrowth in 2000. Nearly 70% of the regrowth reports indicate forest regeneration in hilly, upland, and mountainous environments considered marginal for large-scale agriculture and ranching. Our estimates of the human footprint are conservative because they do not resolve very small-scale deforestation, low-intensity logging, and unreported secondary regrowth, nor do they incorporate other impacts on tropical forest ecosystems, such as fire and hunting. Our results highlight the enormous geographic extent of forest change throughout the humid tropics and the considerable limitations of the science and technology available for such a synthesis.

    Transits of Venus are among the rarest predictable astronomical event that humans can enjoy, and the 2012 transit will be visible by almost all the people on Earth. It is our job as educators to bring out the thrill of being able to see the tiny dot of Venus silhouetted against the solar disk even with just a simple eye-protection filter. My Website at http://www.transitofvenus.info brings together not only historical information about the five previous transits of Venus that were observed through the 20th century--1639, 1761, 1769, 1874, and 1882--but also the scientific work carried out at the 2004 transit and at recent transits of Mercury. Based on space observations of the 1999 transit of Mercury with NASA's Transition Region and Coronal Explorer (TRACE), Glenn Schneider and I provided proof of the contemporary explanation of the black-drop effect as an amalgam of instrumental point-spread and solar limb-darkening [1]. Based on observations of the changes in the total solar irradiance during the transit, we provided an analysis of this solar-system analogue to exoplanet transits [2]. High-resolution (0.5 arcsec pixels) observations of ingress and egress with TRACE during the 2004 transit provided information about the visibility of Venus's atmosphere through its refraction of sunlight, interpreted with Venus Express observations [3]. We anticipate observing the 2012 transit with groundbased facilities of the University of Hawaii at Haleakala, and of the National Solar Observatory at Sacramento Peak, and Kitt Peak, as well as with NASA and JAXA spacecraft, including Solar Dynamics Observatory, ACRIMsat, and Hinode. The Program Group on Public Education on the Occasions of Eclipses and Transits of Commission 46 on Education and Development of the International Astronomical Union, which I chair, looks forward to participating in Education and Public Outreach efforts related to the 2012 transit.

    Historically, the Carpathian Basin was the final destination for many nomadic peoples who migrated westward from Inner and Central Asia towards Europe. Proto-Hungarians (Steppe Magyars) were among those who came from the East, the Eurasian Steppe in the early middle ages. In order to detect the paternal genetic contribution from nomadic Steppe tribes, we tested 966 samples from Central Asian (Uzbekistan, Kazakhstan), Inner Asian (Mongolians and Buryats in Mongolia) and Hungarian-speaking European (Hungarian, Sekler and Csango) populations. We constructed median-joining networks of certain haplogroups in Hungarian-speaking European, and Altaic-speaking Central and Inner Asian populations. We estimated that the possible paternal genetic contribution from the above described populations among contemporary Hungarian speaking populations ranged between 5% and 7.4%. It is lowest among Hungarians from Hungary (5.1%), while higher among Hungarian-speaking groups in Romania, notably Sekler (7.4%) and Csango (6.3%). However, these results represent only an upper limit. Actual Central/Inner Asian admixture might be somewhat lower as some of the related lineages may have come from a common third source. The main haplogroups responsible for the Central/Inner Asian admixture among Hungarians are J2*-M172 (xM47, M67, M12), J2-L24, R1a-Z93; Q-M242 and E-M78. Earlier studies showed very limited Uralic genetic influence among Hungarians, and based on the present study, Altaic/Turkic genetic contribution is also not significant, although significantly higher than the Uralic one. The conclusion of this study is that present-day Hungarian speakers are genetically very similar to neighbouring populations, isolated Hungarian speaking groups having relatively higher presence of Central and Inner Asian genetic elements. At the same time, the reliable historical and genetic conclusions require an extension of the study to a significantly larger database with deep haplogroup resolution

  7. Contemporary transatlantic developments concerning compelled medical treatment of pregnant women.

    1995-05-01

    This paper had identified a contemporary ethicolegal dilemma concerning the circumstances, if any, in which a pregnant woman's refusal of medical treatment may be judicially overridden either in her interests or those of the unborn child. On the one hand, the obstetrician will be concerned about the interests of both his patients in potentially life-threatening situations when they can be protected by what might be regarded as relatively straightforward procedures and where to fail to take those steps might expose the practitioner (at least outside New Zealand where its accident compensation legislation has impact in this regard) to allegations of negligence. On the other hand, the imposition of treatment in these circumstances will necessarily interfere with the woman's rights of autonomy and self-determination. In such cases also, the conduct of medical procedures in the face of an express prohibition by the woman may give rise to liability for battery. (In New Zealand, such a potential liability would not, in the writer's view, be affected by the prohibition on proceedings for damages for medical misadventure as contained in the Accident Rehabilitation and Compensation Insurance Act 1992.) At the heart of an analysis of this issue is the status of the fetus as it is the fact of the woman patient's pregnancy which distinguishes the cases discussed in this paper from others in which the Courts have had to deal with refusals of treatment by those competent to do so. In regard to this aspect, the approach of the Courts in various jurisdictions has arguably been confused and contradictory.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:7677674

  8. Possible contemporary evaporites formation at the Martian Northern Polar Cap

    Losiak, Anna; Czechowski, Leszek

    Evaporitic minerals are abundant on the surface of Mars (e.g., Wentworth et al. 2005, Velbel 2012, Clark and Van Hart 1981, Wang et al. 2006, Kuzmin et al. 2009), especially within the Circumpolar Dune Field and on the Northern Ice Cap itself (e.g., Langevin et al., 2005, Roach et al. 2007, Horgan et al. 2009, Masse et al. 2010, 2012). Most of their proposed formation mechanisms require significant amounts of liquid water and are thus not possible under current Martian conditions (Arvidson et al. 2006, Andrews-Hanna et al. 2007, Fishbaugh et al. 2007, Szynkiewicz et al. 2010). Some authors have considered the potential role of ice and ice- or snowmelt-related alteration in the weathering of Martian materials (e.g., Catling et al. 2006, Zolotov and Mironenko 2007, Niles and Michalski 2009, Masse et al. 2010). However, none of those studies discussed details of the process leading to the formation of the evaporites or the timing of the processes. The aim of this paper is to model numerically if the current radiant heating is sufficient to melt a thin layer of ice surrounding a single dust grain exposed within the south facing side of the Martian North Polar Cap trench. The results of our initial study suggest that for dust grains with basaltic properties and ice with low values of coefficient of heat conduction, and solar constant = 492 W/m2 liquid water may exist below a dust grain for up to 4 hours a sol. This suggest that contemporary evaporites formation on Martian Polar Cap is possible.

  9. Bodystorming: effects of collaboration and familiarity on improvising contemporary dance.

    2015-09-01

    In contemporary dance, cognitive events are not necessarily restricted "to the skin or skull of an individual" (Hutchins in Int Encycl Soc Behav Sci 2068-2072, 2001) but distributed across dancers during collaborative improvisation. There is some experimental evidence of greater output when people perform problem-solving tasks alone. However, when a task is challenging and paired participants are familiar with each other, pairwise and emergent outcomes are more plentiful than solo outcomes. We investigate these factors in the context of dance with the broad hypothesis that innovation is enhanced when dancers improvise together compared with when they improvise alone. Dancers (N = 10) in a professional company improvised for 2 min alone and then with another dancer. Dancer familiarity (familiar, unfamiliar) and task (expressive, non-expressive) were crossed (within-subjects). The improvisations were video-recorded over 2 h in the dancers' usual improvisation space. After each improvisation, the dancers: stated the number of movement ideas expressed and rated task ease, satisfaction, interest, novelty, originality and clarity. In both tasks, there was a tendency for self-report of a greater number of movement ideas expressed in familiar and unfamiliar pairs than alone. Ratings of task ease, satisfaction, interest, clarity, etc. were slightly higher in the unfamiliar pair condition. In the non-expressive task, ratings of the task were higher in pairs (M = 3.02, SD 0.82) than in the solo (M = 2.67, SD 0.96) condition. Distributed creativity, relational cognition and social facilitation are used to interpret the results. PMID:26233523

    2014-05-01

    Heart failure (HF) is an important public health problem, and strategies are needed to improve outcomes and decrease health care resource utilization and costs. Its prevalence has increased as the population ages, and HF continues to be associated with a high mortality rate and frequent need for hospitalization. The total cost of care for patients with HF was $30.7 billion in 2012, and it is estimated to more than double to $69.8 billion by 2030. Given this reality, there has been recent investigation into ways of identifying and preventing HF in patients at risk (stage A HF) and those with cardiac structural and functional abnormalities but no clinical HF symptoms (stage B). For patients who have symptoms of HF (stage C), there has been important research into the most effective ways to decongest patients hospitalized with acute decompensated HF and prevent future hospital readmissions. Successful strategies to treat patients with HF and preserved ejection fraction, which has increased in prevalence, continue to be sought. We are in the midst of a rapid evolution in our ability to care for patients with end-stage HF (stage D) because of the introduction of and improvements in mechanical circulatory support. Left ventricular assist devices used as destination therapy offer an important therapeutic option to patients who do not qualify for heart transplant because of advanced age or excessive comorbidity. This review provides a thorough update on contemporary strategies in the diagnosis and management of HF by stage (A to D) that have emerged during the past several years.

    The acquisition and display of material artefacts is the raison d'être of museums. But what constitutes a museum artefact? Contemporary medicine (biomedicine) is increasingly producing artefacts that do not fit the traditional museological understanding of what constitutes a material, tangible artefact. Museums today are therefore caught in a paradox. On the one hand, medical science and technologies are having an increasing pervasive impact on the way contemporary life is lived and understood and is therefore a central part of the contemporary world. On the other hand, the objects involved in medical diagnostics and therapies are becoming increasingly invisible and intangible and therefore seem to have no role to play as artefacts in a museum context. Consequently, museums are at risk of becoming alienated from an increasingly important part of contemporary society. This essay elaborates the paradox by employing Gumbrecht's (2004) distinction between 'presence' and 'meaning'.

  17. Pleistocene Aridification Cycles Shaped the Contemporary Genetic Architecture of Southern African Baboons

    Plio-Pleistocene environmental change influenced the evolutionary history of many animal lineages in Africa, highlighting key roles for both climate and tectonics in the evolution of Africa’s faunal diversity. Here, we explore diversification in the southern African chacma baboon Papio ursinus sensu lato and reveal a dominant role for increasingly arid landscapes during past glacial cycles in shaping contemporary genetic structure. Recent work on baboons (Papio spp.) supports complex lineage structuring with a dominant pulse of diversification occurring 1-2Ma, and yet the link to palaeoenvironmental change remains largely untested. Phylogeographic reconstruction based on mitochondrial DNA sequence data supports a scenario where chacma baboon populations were likely restricted to refugia during periods of regional cooling and drying through the Late Pleistocene. The two lineages of chacma baboon, ursinus and griseipes, are strongly geographically structured, and demographic reconstruction together with spatial analysis of genetic variation point to possible climate-driven isolating events where baboons may have retreated to more optimum conditions during cooler, drier periods. Our analysis highlights a period of continuous population growth beginning in the Middle to Late Pleistocene in both the ursinus and the PG2 griseipes lineages. All three clades identified in the study then enter a state of declining population size (Nef) through to the Holocene; this is particularly marked in the last 20,000 years, most likely coincident with the Last Glacial Maximum. The pattern recovered here conforms to expectations based on the dynamic regional climate trends in southern Africa through the Pleistocene and provides further support for complex patterns of diversification in the region’s biodiversity.

    Global change requires plant ecologists to predict future states of biological diversity to aid the management of natural communities, thus introducing a number of significant challenges. One major challenge is considering how the many interacting features of biological systems, including ecophysiological processes, plant life histories, and species interactions, relate to performance in the face of a changing environment. We have employed a functional trait approach to understand the individual, population, and community dynamics of a model system of Sonoran Desert winter annual plants. We have used a comprehensive approach that connects physiological ecology and comparative biology to population and community dynamics, while emphasizing both ecological and evolutionary processes. This approach has led to a fairly robust understanding of past and contemporary dynamics in response to changes in climate. In this community, there is striking variation in physiological and demographic responses to both precipitation and temperature that is described by a trade-off between water-use efficiency (WUE) and relative growth rate (RGR). This community-wide trade-off predicts both the demographic and life history variation that contribute to species coexistence. Our framework has provided a mechanistic explanation to the recent warming, drying, and climate variability that has driven a surprising shift in these communities: cold-adapted species with more buffered population dynamics have increased in relative abundance. These types of comprehensive approaches that acknowledge the hierarchical nature of biology may be especially useful in aiding prediction. The emerging, novel and nonstationary climate constrains our use of simplistic statistical representations of past plant behavior in predicting the future, without understanding the mechanistic basis of change.

    With 207 million ha of forest covering 22% of its land area, China ranks fifth in the world in forest area. Rapid economic growth, climate change, and forest disturbances pose new, complex challenges for forest research and management. Progress in meeting these challenges is relevant beyond China, because China's forests represent 34% of Asia's forests and 5% of the worlds' forests. To provide a broader understanding of these management challenges and of research and policies that address them, we organized this special issue on contemporary forest research and management issues in China. At the national level, papers review major forest types and the evolution of sustainable forestry, the development of China's forest-certification efforts, the establishment of a forest inventory system, and achievements and challenges in insect pest control in China. Papers focused on Northern China address historical, social, and political factors that have shaped the region's forests; the use of forest landscape models to assess how forest management can achieve multiple objectives; and analysis and modeling of fuels and fire behavior. Papers addressing Central and South China describe the "Grain for Green" program, which converts low productivity cropland to grassland and woodland to address erosion and soil carbon sequestration; the potential effects of climate change on CO(2) efflux and soil respiration; and relationships between climate and net primary productivity. China shares many forest management and research issues with other countries, but in other cases China's capacity to respond to forest management challenges is unique and bears watching by the rest of the world.

Velocity and diffusion are also potential measurements. Two unique capabilities of contemporary interest are the ability to image the spatial distribu-tion of relaxation parameters which give information about the local tissue characteristics, and the ability of NMR spectroscopy to sample (not image) the energy state of phosphorous in selected regions of the body. A third attribute of importance is that possible tissue heating seems to be the only hazard and this can be controlled.

CONCLUSIONS: Our experience suggest that contemporary perioperative mortality for combined aortic and renal repair has improved compared with earlier reports; however, perioperative mortality for simultaneous reconstruction remains greater than repair of aortic disease alone. Moreover, a lower rate of favorable hypertension response was observed after combined correction compared with renal artery repair alone. These differences suggest that aortic and renal artery repair should only be combined for clinical indications rather than for prophylactic repair of clinically silent disease. PMID:8651746

    have significantly lower (by 55%) thermal conductivity and increased (by almost 20%) specific heat capacity at 90 days after laboratory production. At the same time, even though porosity values are higher for the PCM-enhanced renders, compared to the reference mixtures, their capillary absorption coefficient is significantly reduced (up to 60%). This is of great importance in the case of renders and may well be an indication for better expected durability in the long-term. Regarding the mechanical properties of the laboratory composites, PCM addition seems to have a negative effect on the hydraulic plasters. In contrast, when PCM is added to the hydrated lime-based plaster, no change is observed for the flexural strength, while the compressive strength is notably improved (up to 36%). The apparently improved properties of the PCM-enhanced plasters render them particularly appropriate for application in southern European climatic conditions. Due to their compatibility with traditional substrate materials (e.g. natural stone), the aforementioned composites may be used not only in new contemporary structures, but also for the renovation and retrofitting of existing buildings. The lime-based nature of their matrix and their physico-mechanical properties further extend their applicability to listed and monumental buildings.

    Context Androgen deprivation therapy (ADT) for prostate cancer (PCa) represents one of the most effective systemic palliative treatments known for solid tumors. Although clinical trials have assessed the role of ADT in patients with metastatic and advanced locoregional disease, the risk–benefit ratio, especially in earlier stages, remains poorly defined. Given the mounting evidence for potentially life-threatening adverse effects with short- and long-term ADT, it is important to redefine the role of ADT for this disease. Objective Review the published experience with currently available ADT approaches in various contemporary clinical settings of PCa and reported serious treatment-related adverse events. This review addresses the level of evidence associated with the use of ADT in PCa, focusing upon survival outcome measures. Furthermore, this paper discusses evolving approaches targeting androgen receptor signaling pathways and emerging evidence from clinical trials with newer compounds. Evidence acquisition A comprehensive review of the literature was performed, focusing on data from the last 10 yr (January 2000 to July 2011) and using the terms androgen deprivation, hormone treatment, prostate cancer and adverse effects. Abstracts from trials reported at international conferences held in 2010 and 2011 were also evaluated. Evidence synthesis Data from randomized controlled trials and population-based studies were analyzed in different clinical paradigms. Specifically, the role of ADT was evaluated in patients with nonmetastatic disease as the primary and sole treatment, in combination with radiation therapy (RT) or after surgery, and in patients with metastatic disease. The data suggest that in men with nonmetastatic disease, the use of primary ADT as monotherapy has not shown a benefit and is not recommended, while ADT combined with conventional-dose RT (<72 Gy) for patients with high-risk disease may delay progression and prolong survival.

    2015-12-01

    Landscape genetics seeks to determine the effect of landscape features on gene flow and genetic structure. Often, such analyses are intended to inform conservation and management. However, depending on the many factors that influence the time to reach equilibrium, genetic structure may more strongly represent past rather than contemporary landscapes. This well-known lag between current demographic processes and population genetic structure often makes it challenging to interpret how contemporary landscapes and anthropogenic activity shape gene flow. Here, we review the theoretical framework for factors that influence time lags, summarize approaches to address this temporal disconnect in landscape genetic studies, and evaluate ways to make inferences about landscape change and its effects on species using genetic data alone or in combination with other data. Those approaches include comparing correlation of genetic structure with historical versus contemporary landscapes, using molecular markers with different rates of evolution, contrasting metrics of genetic structure and gene flow that reflect population genetic processes operating at different temporal scales, comparing historical and contemporary samples, combining genetic data with contemporary estimates of species distribution or movement, and controlling for phylogeographic history. We recommend using simulated data sets to explore time lags in genetic structure, and argue that time lags should be explicitly considered both when designing and interpreting landscape genetic studies. We conclude that the time lag problem can be exploited to strengthen inferences about recent landscape changes and to establish conservation baselines, particularly when genetic data are combined with other data.

    Contemporary human populations conform to ecogeographic predictions that animals will become more compact in cooler climates and less compact in warmer ones. However, it remains unclear to what extent this pattern reflects plastic responses to current environments or genetic differences among populations. Analyzing anthropometric surveys of 232,684 children and adults from across 80 ethnolinguistic groups in sub-Saharan Africa, Asia and the Americas, we confirm that body surface-to-volume correlates with contemporary temperature at magnitudes found in more latitudinally diverse samples (Adj. R2 = 0.14-0.28). However, far more variation in body surface-to-volume is attributable to genetic population structure (Adj. R2 = 0.50-0.74). Moreover, genetic population structure accounts for nearly all of the observed relationship between contemporary temperature and body surface-to-volume among children and adults. Indeed, after controlling for population structure, contemporary temperature accounts for no more than 4% of the variance in body form in these groups. This effect of genetic affinity on body form is also independent of other ecological variables, such as dominant mode of subsistence and household wealth per capita. These findings suggest that the observed fit of human body surface-to-volume with current climate in this sample reflects relatively large effects of existing genetic population structure of contemporary humans compared to plastic response to current environments.

  12. Contemporary post-humanism: technological and human singularity.

    PubMed

    Colombetti, Elena

    2014-01-01

    Posthumanism entails the idea of transcendence of the human being achieved through technology. The article begins by distinguishing perfection and change (or growth). It also attempts to show the anthropological premises of posthumanism itself and suggests that we can identify two roots: the liberal humanistic subject (autonomous and unrelated that simply realizes herself/himself through her/his own project) and the interpretation of thought as a computable process. Starting from these premises, many authors call for the loosening of the clear boundaries of one's own subject in favour of blending with other beings. According to these theories, we should become post-human: if the human being is thought and thought is a computable process, whatever is able to process information broader and faster is better than the actual human being and has to be considered as the way towards the real completeness of the human being itself. The paper endeavours to discuss the adequacy of these premises highlighting the structural dependency of the human being, the role of the human body, the difference between thought and a computational process, the singularity of some useless and unexpected human acts. It also puts forward the need for axiological criteria to define growth as perfectionism. PMID:25684377

I summarise some features of the 20th century eugenics movement; describe the contemporary standard of care in the USA regarding PNS, PND, abortion and PGD; and demonstrate that the 'old eugenics' the contemporary standard of care share the underlying view that social resources should be invested to prevent the birth of people with certain characteristics. This comparison makes evident the difficulty of crafting moral arguments that treat some uses of PNS, PND, abortion and PGD as licit and others as illicit. PMID:27161556

    This report draws upon data from a variety of sources to estimate the size, scope, and growth rate of the contemporary tissue engineering enterprise. At the beginning of 2001, tissue engineering research and development was being pursued by 3,300 scientists and support staff in more than 70 startup companies or business units with a combined annual expenditure of over $600 million. Spending by tissue engineering firms has been growing at a compound annual rate of 16%, and the aggregate investment since 1990 now exceeds $3.5 billion. At the beginning of 2001, the net capital value of the 16 publicly traded tissue engineering startups had reached $2.6 billion. Firms focusing on structural applications (skin, cartilage, bone, cardiac prosthesis, and the like) comprise the fastest growing segment. In contrast, efforts in biohybrid organs and other metabolic applications have contracted over the past few years. The number of companies involved in stem cells and regenerative medicine is rapidly increasing, and this area represents the most likely nidus of future growth for tissue engineering. A notable recent trend has been the emergence of a strong commercial activity in tissue engineering outside the United States, with at least 16 European or Australian companies (22% of total) now active.

    Contributing roughly half of the biosphere's net primary production (NPP), photosynthesis by oceanic phytoplankton is a vital link in the cycling of carbon between living and inorganic stocks. Each day, more than a hundred million tons of carbon in the form of CO2 are fixed into organic material by these ubiquitous, microscopic plants of the upper ocean, and each day a similar amount of organic carbon is transferred into marine ecosystems by sinking and grazing. The distribution of phytoplankton biomass and NPP is defined by the availability of light and nutrients (nitrogen, phosphate, iron). These growth-limiting factors are in turn regulated by physical processes of ocean circulation, mixed-layer dynamics, upwelling, atmospheric dust deposition, and the solar cycle. Satellite measurements of ocean colour provide a means of quantifying ocean productivity on a global scale and linking its variability to environmental factors. Here we describe global ocean NPP changes detected from space over the past decade. The period is dominated by an initial increase in NPP of 1,930 teragrams of carbon a year (Tg C yr(-1)), followed by a prolonged decrease averaging 190 Tg C yr(-1). These trends are driven by changes occurring in the expansive stratified low-latitude oceans and are tightly coupled to coincident climate variability. This link between the physical environment and ocean biology functions through changes in upper-ocean temperature and stratification, which influence the availability of nutrients for phytoplankton growth. The observed reductions in ocean productivity during the recent post-1999 warming period provide insight on how future climate change can alter marine food webs. PMID:17151666

    Kant's concept of autonomy and the Kantian notion of autonomy are often conflated in bioethics. However, the contemporary Kantian notion has very little at all to do with Kant's original. In order to further bioethics discourse on autonomy, I critically distinguish the contemporary Kantian notion from Kant's original concept of moral autonomy. I then evaluate the practical relevance of both concepts of autonomy for use in bioethics. I argue that it is not appropriate to appeal to either concept toward assessing which patients we ought to respect as autonomous. Finally, I sketch criteria for what I take to be a more promising concept of autonomy for patients.

    The current review and synthesis serves to define and contextualize fear of the unknown relative to related constructs, such as intolerance of uncertainty, and contemporary models of emotion, attachment, and neuroticism. The contemporary models appear to share a common core in underscoring the importance of responses to unknowns. A recent surge in published research has explored the transdiagnostic impact of not knowing on anxiety and related pathologies; as such, there appears to be mounting evidence for fear of the unknown as an important core transdiagnostic construct. The result is a robust foundation for transdiagnostic theoretical and empirical explorations into fearing the unknown and intolerance of uncertainty.

    This paper explores the architecture, theoretical foundations, and paradigms of contemporary cybernetics from perspectives of cognitive informatics (CI) and computational intelligence. The modern domain and the hierarchical behavioral model of cybernetics are elaborated at the imperative, autonomic, and cognitive layers. The CI facet of cybernetics is presented, which explains how the brain may be mimicked in cybernetics via CI and neural informatics. The computational intelligence facet is described with a generic intelligence model of cybernetics. The compatibility between natural and cybernetic intelligence is analyzed. A coherent framework of contemporary cybernetics is presented toward the development of transdisciplinary theories and applications in cybernetics, CI, and computational intelligence.

    Diabetes Mellitus (Madhumeha) is a well-known clinical syndrome since antiquity. First time the role of Diet in the prevention, etiology and treatment of Diabetes was mentioned in Ayurveda under the heading of Prameha and Madumeha. Caraka Samhita, Susruta Samhita and other Ayurvedic classics have appropriate descriptions on the role of diet, habits and life style in Prameha and Madhumeha, which is akin to Diabetes. Recent modern (contemporary) Researches and statistics support these descriptions. Aim of this article is to alarm people regarding role of diet and lifestyle in Diabetes through Ayurvedic approach and contemporary scientific correlation with support of clinical and statistical data.

  4. Growth hormone.

    PubMed

    Bidlingmaier, Martin; Strasburger, Christian J

    2010-01-01

    Human growth hormone (hGH) is a proteohormone secreted by the pituitary gland. It acts through binding to the hGH receptor, inducing either direct effects or initiating the production of insulin-like growth-factor I (IGF-I), the most important mediator of hGH effects. Growth hormone is primarily known to promote longitudinal growth in children and adolescents, but has also various important metabolic functions throughout adult life. Effects of hGH on the adult organism are well established from studies with recombinant growth hormone (rhGH) therapy in growth hormone deficient subjects. In this particular group of patients, replacement of hGH leads to increased lipolysis and lean body mass, decreased fat mass, improvements in VO(2max), and maximal power output. Although extrapolation from these findings to the situation in well trained healthy subjects is impossible, and controlled studies in healthy subjects are scarce, abuse of hGH seems to be popular among athletes trying to enhance physical performance. Detection of the application of rhGH is difficult, especially because the amino acid sequence of rhGH is identical to the major 22,000 Da isoform of hGH normally secreted by the pituitary. Furthermore, some physiological properties of hGH secretion also hindered the development of a doping test: secreted in a pulsatile manner, it has a very short half-life in circulation, which leads to highly variable serum levels. Concentration alone therefore cannot prove the exogenous administration of hGH.Two approaches have independently been developed for the detection of hGH doping: The so-called "marker approach" investigates changes in hGH-dependent parameters like IGF-I or components of bone and collagen metabolism, which are increased after hGH injection. In contrast, the so-called "isoform approach" directly analyses the spectrum of molecular isoforms in circulation: the pituitary gland secretes a spectrum of homo- and heterodimers and - multimers of a variable

  5. Pyrazoles as potential anti-angiogenesis agents: a contemporary overview

    Kasiotis, Konstantinos M.; Tzanetou, Evangelia N.; Haroutounian, Serkos A.

    2014-01-01

    Angiogenesis is a mulit-step process by which new blood vessels are formed from preexisting vasculature. It is a key rate limiting factor in tumor growth since new blood vessels are necessary to increase tumor size. In this context it has been shown that anti-angiogenic factors can be used in cancer therapy. Among the plethora of heterocyclic compounds administered as anti-angiogenesis agents, pyrazoles constitute one of the bottlenecks of this category. Currently, several pyrazole based compounds are administered or are in Phase II and III trials and new targets emerge. It is highly possible that the advent of the next two decades will lead to the discovery and use of additional pyrazoles whose anti-angiogenic profile will position them in the forefront of the battle of various malignancies. The present review is an attempt to focus on those pyrazoles that arise as anti-angiogenesis agents commenting both on the chemistry and bioactivity that these exhibit aiming to contribute to the perspectives that they hold for future research.

  6. Contemporary Evaluation and Management of the Diabetic Foot

    PubMed Central

    Sumpio, Bauer E.

    2012-01-01

    Foot problems in patients with diabetes remain a major public health issue and are the commonest reason for hospitalization of patients with diabetes with prevalence as high as 25%. Ulcers are breaks in the dermal barrier with subsequent erosion of underlying subcutaneous tissue that may extend to muscle and bone, and superimposed infection is a frequent and costly complication. The pathophysiology of diabetic foot disease is multifactorial and includes neuropathy, infection, ischemia, and abnormal foot structure and biomechanics. Early recognition of the etiology of these foot lesions is essential for good functional outcome. Managing the diabetic foot is a complex clinical problem requiring a multidisciplinary collaboration of health care workers to achieve limb salvage. Adequate off-loading, frequent debridement, moist wound care, treatment of infection, and revascularization of ischemic limbs are the mainstays of therapy. Even when properly managed, some of the foot ulcers do not heal and are arrested in a state of chronic inflammation. These wounds can frequently benefit from various adjuvants, such as aggressive debridement, growth factors, bioactive skin equivalents, and negative pressure wound therapy. While these, increasingly expensive, therapies have shown promising results in clinical trials, the results have yet to be translated into widespread clinical practice leaving a huge scope for further research in this field.

  7. Contemporary Concepts for the Bilateral Cleft Lip and Nasal Repair

    PubMed Central

    Khosla, Rohit K.; McGregor, Jyoti; Kelley, Patrick K.; Gruss, Joseph S.

    2012-01-01

    The bilateral cleft lip and nasal deformity presents a complex challenge for repair. Surgical techniques continue to evolve and are focused on primary anatomic realignment of the tissues. This can be accomplished in a single-stage or two-stage repair early in infancy to provide a foundation for future growth of the lip and nasal tissue. Most cleft surgeons currently perform a single-stage repair for simplifying patient care. Certain institutions utilize presurgical orthopedics for alignment of the maxillary segments and nasal shaping. Methods for the bilateral cleft lip repair are combined with various open and closed rhinoplasty techniques to achieve improved correction of the primary nasal deformity. There is recent focus on shaping the nose for columellar and tip support, as well as alar contour and alar base position. The authors will present a new technique for closure of the nasal floor to prevent the alveolar cleft fistula. Although the alveolar fistula is closed, alveolar bone grafting is still required at the usual time in dental development to fuse the maxilla. It is paramount to try and minimize the stigmata of secondary deformities that historically have been characteristic of the repaired bilateral cleft lip. A properly planned and executed repair reduces the number of revisions and can spare a child from living with secondary deformities. PMID:24179448

  12. Contemporary Japanese view of life and death as depicted in the film Departures (Okuribito).

    PubMed

    Asai, Atsushi; Fukuyama, Miki; Kobayashi, Yasunori

    2010-06-01

    Through films, we can see many aspects of a country and its times: culture, morality and religion, and views on life and death. The best films can both entertain audiences and provide viewers with opportunities to think about fundamental human problems. In this article, we use Departures (Okuribito) to examine the contemporary Japanese view of life and death. All sorts of deaths are depicted and each scene provides an insight into the contemporary Japanese view of death. We use the medium of film to consider the issue of death: what death is, the relationship that exists between life and death, and how the impurity and dignity of the dead are recognised by contemporary Japanese people. The ritual of 'encoffinment' will also be discussed, and what it suggests and reveals about Japanese views on what happens to a person when they die, and what requirements exist for someone to be able to depart from this world to the afterlife. The view of death depicted in Departures is thought to accept and even hope for a worldview that postulates continuity between life and death, wherein not only the soul but also personal individuality continues on as it existed in life. The rite of encoffinment is required to relieve the family's grief as well as to wipe away the impurity of the dead. The Japanese traditional view that the 'dead are impure' seems to die hard. It is also suggested that complicated and ambivalent attitudes towards the dead exist among contemporary Japanese people. PMID:21393271

  15. Contemporary Ceramic Total Hip Arthroplasty in Patients with Cerebral Palsy: Does It Work?

    PubMed Central

    Yoon, Byung-Ho; Ha, Yong-Chan; Koo, Kyung-Hoi

    2015-01-01

    Background Adult patients with cerebral palsy (CP), who have advanced degenerative arthritis of the hip, have been treated with resection arthroplasty and arthrodesis. Although total hip arthroplasty (THA) has also been used as one of the alternative options, there are few studies on contemporary bearings used in THA. Therefore, we evaluated the results of the contemporary ceramic-on-ceramic THA in adult patients with CP. Methods From January 2005 to December 2007, five adult CP patients (5 hips) underwent THA using contemporary ceramic-on-ceramic bearings. All patients were able to stand or ambulate with intermittent use of assistive devices at home. We retrospectively reviewed the series to determine the results of THA in terms of pain relief, improved function, and durability of prosthesis. Results There were 3 men and 2 women with a mean age of 35.9 years. All patients had pain relief without decline in mobility postoperatively. One hip was dislocated, which was treated successfully with closed reduction and an abduction brace for 2 months. There was no ceramic fracture, loosening, or osteolysis during the mean follow-up of 6.8 years (range, 5.8 to 8.3 years). Conclusions Cementless THA using contemporary ceramic-on-ceramic bearings is a useful option for the treatment of advanced degenerative arthritis of the hip in ambulatory adults with CP.

  17. The "contemporary synthesis": when politically inclusive genomic science relies on biological notions of race.

    PubMed

    Fullwiley, Duana

    2014-12-01

    This essay outlines the emergence of a contemporary synthesis regarding racial thinking in genetic science and in society more broadly. A departure from what Julian Huxley in 1942 termed the "modern synthesis," the contemporary version does not purport to leave race thinking behind in favor of evolution, population genetics, and population-based accounts of natural selection and human diversity. Specifically, the contemporary synthesis blends old concepts (such as that of pure human "types," located within continental land masses) with new attitudes (democratic inclusion, multicultural diversity, and anti-racism). Through various examples, the essay shows how this new synthesis combines ideas about human biological difference that draw on measures of physical characteristics and human genetic material that are both race and population based, yet conflated. This specific amalgam allows old notions of racial types to thrive through conceptual framings that comprise ideas that were once imagined to have the potential to liberate society from racial thinking--and that today remain attached to ideas of progress. As an emergent dynamic, the contemporary synthesis holds the possibility of reinvigorating racism, while simultaneously possessing the potential to promote antiracist science education, disease awareness, and social justice efforts.
