  1. Transportation technology transitions and macroeconomic growth -- Contemporary evidence

    SciTech Connect

    Santini, D.J.

    1994-12-31

    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.

    Schell, Lawrence M; Gallo, Mia V; Ravenscroft, Julia

    2009-01-01

    Over the past 100 years, the study of environmental influences on human physical growth and development has focused on the influences of social and economic factors; family and household characteristics; urbanization/modernization; nutrition; and features of the physical environment such as altitude, temperature and climate. Continuing in this tradition are current investigations into the roles of pollutants and other aspects of the human-made environment in affecting patterns of human growth and development, specifically the timing of sexual maturation and the development of obesity. Some of the methodological problems in conducting such studies are presented, as are results from an ongoing investigation among one Native American community that show relationships of pollutants to sexual maturation, overweight/obesity and thyroid system function which can impact growth and maturation.

    2011-10-01

    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

  7. Contemporary reliance on bicarbonate acquisition predicts increased growth of seagrass Amphibolis antarctica in a high-CO2 world.

    PubMed

    2014-01-01

    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.

    1997-01-01

    The diagnosis and management of aniseikonia has become a lost art. Refractive surgery and intraocular lens implantation has created a new patient population of anisometropia. Measurement of aniseikonia through instrumentation such as the space eikonometer is not readily available. Therefore, estimating the degree of aniseikonia based on the dioptral differences between the two eyes may be the most practical approach. The optical principles of spectacle magnification can be translated by the prescribing eye doctor to reduce ocular image disparity. Contemporary lens designs, such as hi-index and aspherics, allow the practitioner to modify shape and power factors to achieve higher levels of aniseikonic correction in a cosmetically fashionable pair of spectacles.

  16. 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.

    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

    2010-01-01

    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.

    2010-04-01

    Mastocytosis denotes a wide range of disorders characterized by having abnormal growth and accumulation of mast cells. Mast cells contain histamine and other inflammatory mediators, which have diverse actions within the body, and play crucial roles in acquired and innate immunity. The diverse actions of these inflammatory mediators can lead to puzzling symptoms in individuals with mastocytosis. These symptoms can include flushing, pruritus, nausea, vomiting, abdominal pain, diarrhea, vascular instability, and headache. These clinical features generally divide into cutaneous and systemic manifestations, giving rise to the two divisions of mastocytosis: cutaneous mastocytosis (CM) and systemic mastocytosis. CM has a highly favorable clinical prognosis. Systemic mastocytosis has a range of severity, with the milder forms often remaining chronic conditions, while the severe forms have rapid complex courses with poor prognoses. Generally, treatment is aimed at avoiding mast cell degranulation, inhibiting the actions of the constitutive mediators released by mast cells and, in severe cases, cytoreductive and polychemotherapeutic agents. Behavioral intervention includes avoidance of triggers, such as heat, cold, pressure, exercise, sunlight, and strong emotions. Treatment for released histamine and other inflammatory mediators includes H1 antihistamines, H2 antihistamines, proton pump inhibitors, anti-leukotriene agents, and injectible epinephrine (for possible anaphylaxis). For severe cases, treatment includes cytoreductive agents (interferon alpha, glucocorticoids, and cladribine) and polychemotherapeutic agents (daunomycin, etoposide, and 6-mercaptopurine). For very specific and severe cases, tyrosine kinase inhibitors, imatinib and midostaurine, have shown promise.

    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

    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.

    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

    While contemporary mental health services have been marked by the burgeoning of outpatient and preventive care, the historiography of psychiatry remains largely tied to the study of custodial and palliative treatment.The work in which contemporary psychiatry has been involved cannot be adequately understood as a singular, autonomous enterprise based in a residential facility. It has become a technoscience that operates in numerous settings and alongside multiple sciences, technologies and decision-makers. This paper explores what it might mean to 'deinstitutionalize' the history of contemporary psychiatry by examining the case of social therapy for sex offenders in West Germany.

    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

  5. 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.

  6. Women and class structure in contemporary Japan.

    PubMed

    Shirahase, S

    2001-09-01

    The main purpose of this study is to examine how to determine the class position of women, especially married women, in Japan. This study examines three different approaches to conceptualizing women's position in the class structure: the conventional approach, the individual approach, and the dominance approach. Since 1975, the overall rate of female labour force participation in Japan has increased, and given this growth, particularly of employees working outside home, I discuss whether the increased entry of women, particularly married women, into the labour market challenges the conventional way of assigning class positions to women by simply deriving them from their husband's class positions. The data set used in this study is derived from the 1995 Japanese Social Stratification and Mobility Survey. An examination of class distributions suggests that the pictures of macro-class structure provided by the conventional approach and the dominance approach show very little difference. Married women who belong to the female-dominant family still form a very small minority of all married women in the society. Furthermore, the male-dominant family shows the greatest stability over the life course whereas the female-dominant family, where the wife experiences withdrawal from the labour market, is least stable. The increasing number of married women in the labour market, thus, has not yet become a major threat to the conventional way of assigning women to a class position in contemporary Japan. Women, even among those working on a full-time basis, perceive their position in the stratification system using not only their own work, but also their husband's. In contrast, men's perception is determined by their own education and employment, not by their wives'. This asymmetry in the effect of the husband's class and of the wife's class on class identification is related not only to gender inequality within the labour market but also to the division of labour by gender within

  7. Fitness in contemporary dance: a systematic review.

    PubMed

    2009-07-01

    It has been suggested that dancers are less fit compared to other athletes. However, the majority of studies make their arguments based on data deriving mainly from ballet. Therefore, the aim of the current review was to investigate: a) aerobic and anaerobic fitness, muscular strength and body composition characteristics in contemporary dancers of different levels, and b) whether supplementary exercise interventions, in addition to normal dance training, further improves contemporary dance performance. Three databases (Medline, Cochrane and the Cumulative Index to Nursing & Allied Health research database) were searched to identify publications regarding the main fitness components of contemporary professional and student dancers. At a professional level, it appears that contemporary dancers demonstrate higher maximal oxygen uptake and higher scores in muscular endurance than ballet dancers. However, contemporary dance students are equally fit compared to their ballet counterparts and their body composition is also very similar. Only two studies have investigated the effects of supplementary exercise training on aspects of dance performance. Further research is needed in order to confirm preliminary data, which suggest that the implementation of additional fitness training is beneficial for contemporary dance students to achieve a better performance outcome.

  8. The mandibular muscles in contemporary orthodontic practice: a review.

    PubMed

    Woods, M G

    2017-03-01

    It is widely accepted that all dentists should have a thorough understanding of the muscles involved in moving or stabilizing the mandible. However, there is still much discussion regarding the influence of the mandibular muscles on normal facial growth and dental development, as well as on orthodontic treatment and post-treatment stability. Potential patients with different underlying vertical muscle patterns will have differences in the expected directions of future mandibular growth, lateral profile shape, facial and arch widths and vertical occlusal relationships. In turn, thorough diagnoses are likely to lead to differences in individual aims and objectives, treatment plans, timing of commencement, mechanical design, lateral profile and smile-aesthetics outcomes, choice of retention and plans for long-term maintenance. The potential influence of the mandibular muscles on normal morphologic variation and the soft tissue implications on contemporary orthodontic treatment and stability will be addressed in this review.

    PubMed

    2015-01-01

    The new positron emission tomography (PET/CT) methods for neuroendocrine tumors detection are presented and compared with classic, conventional methods. Conventional methods use a gamma scintillation camera for patients with neuroendocrine tumor imaging, after intravenous injection of one of the following radiopharmaceuticals: 1) somatostatin analogues labeled with indium-111 (111In-pentetreotide) or technetium-99m (99mTc-EDDA/HYNIC-TOC); 2) noradrenaline analogue labeled with iodine-131 or -123 (131/123I-MIBG); or 3) 99mTc(V)-DMSA. Contemporary methods use PET/CT equipment for patients with neuroendocrine tumor imaging, after intravenous injection of pharmaceuticals labeled with positron emitters [fluorine-18 (18F), galium-68 (68Ga), or carbon-11 (11C)]: 1) glucose analogue (18FDG); 2) somatostatin analogue (68Ga-DOTATOC/68Ga-DOTATATE/68Ga-DOTANOC); 3) aminoacid precursors of bioamines: [a) dopamine precursor 18F-DOPA (6-18F-dihydroxyphenylalanine), b) serotonin precursor 11C-5HTP (11C-5-hydroxytryptophan)]; or 4) dopamine analogue 18F-DA (6-18F-fluorodopamine). Conventional and contemporary (PET/ CT) somatostatin receptor detection showed identical high spe- cificity (92%), but conventional had very low sensitivity (52%) compared to PET/CT (97%). It means that almost every second neuroendocrine tumor detected by contemporary method cannot be discovered using conventional (classic) method. In metastatic pheochromocytoma detection contemporary (PET/ CT) methods (18F-DOPA and 18F-DA) have higher sensitivity than conventional (131I/123I-MIBG). In medullary thyroid carcinoma diagnostics contemporary method ([18F-DOPA) is more sensitive than conventional 99mTc(V)-DMSA method, and is similar to 18FDG, computed tomography and magnetic resonance. In carcinoid detection contemporary method (18F-DOPA) shows similar results with contemporary somatostatin receptor detection, while for gastroenteropancreatic neuroendocrine tumors it is worse. To conclude, contemporary (PET

    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.

    With conflicting evidence regarding the effectiveness of manual therapy calls have arisen within some quarters of the physiotherapy profession challenging the continued use of manual skills for assessment and treatment. A reconceptualisation of the importance of manual examination findings is put forward, based upon a contemporary understanding of pain science, rather than considering these skills only in terms of how they should "guide" manual therapy interventions. The place for manual examination findings within complex, multidimensional presentations is considered using vignettes describing the presentations of five people with low back pain. As part of multidimensional, individualised management, the balance of evidence relating to the effectiveness, mechanisms of action and rationale for manual skills is discussed. It is concluded that if manual examination and therapeutic skills are used in a manner consistent with a contemporary understanding of pain science, multidimensional patient profiles and a person-centred approach, their selective and judicious use still has an important role.

  14. Contemporary Review on Spontaneous Coronary Artery Dissection.

    2016-07-19

    Spontaneous coronary artery dissection (SCAD) is gaining recognition as an important cause of myocardial infarction, especially in young women. There has been a surge in the diagnosis of SCAD in recent years, presumably due to an increased use of coronary angiography, and the clinical availability and application of high-resolution intracoronary imaging. The improved recognition and diagnosis, together with increased publications and attention through social media, have considerably raised awareness of this condition, which was once believed to be very rare. Recent publications of moderate to large contemporary case series have helped elucidate the early natural history, presenting characteristics (clinical and angiographic), underlying etiology, management, and cardiovascular outcomes with this condition, thus providing observations and important clinical insights of value to clinicians managing this challenging and perplexing patient cohort. The aim of our review is to provide a comprehensive contemporary update of SCAD to aid health care professionals in managing these patients in both the acute and chronic settings.

    Outcomes are, simply put, why a surgeon comes to work each day. For decades, surgeons have insisted on a regular self-examination of outcomes to ensure the optimal treatment of our patients. Clinical research in pediatric surgery has largely subsisted on outcome analysis as it relates to the rudimentary end-result of an operation, utilizing variables such as mortality, operative time, specific complication rates, and hospital length of stay to name a few. Recently, outcomes research has become a more complex endeavor. This issue of Seminars in Pediatric Surgery addresses a wide array of these newfound complexities in contemporary outcomes research. The purpose of this review is to assist the pediatric surgeon in understanding the tools that are used in contemporary outcomes research and to be able to use this information to ask new questions of our patients and ourselves as we continue to strive for excellence in caring for sick infants and children.

    Contemporary visual artists are incorporating genetic concepts into their work, and this work has become prominently featured in numerous museum and gallery exhibitions. Such art uses visual images that represent the language of genomics, the values affected by genetic understanding of the body and the implications of bioengineering. Here, we present various examples of how artists depict aspects of genetics as cultural icons and symbols; in particular, their focus on DNA as information and on the commercialization of genetics research material.

    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.

    This discussion of the issues relating to the problem posed by population explosion in the developing countries and economic growth in the contemporary world covers the following: predictions of economic and social trends; the Malthusian theory of population; the classical or stationary theory of population; the medical triage model; ecological disaster; the Global 2000 study; the limits to growth; critiques of the Limits to Growth model; nonrenewable resources; food and agriculture; population explosion and stabilization; space and ocean colonization; and the limits perspective. 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. It exaggerates the ecological disaster arising out of the exponential growth of population and industry. The gross underestimation of renewable resources is a basic flaw of the model. The most critical weakness of the model is its gross underestimation of the historical trend of technological progress and the technological possiblities within industry and agriculture. The model does correctly emphasize

    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.

    Darwin's On the Origin of Species[1] introduced the world to the most fundamental concept in biological sciences - evolution. However, in the 150 years following publication of his seminal work, much has been made of the fact that Darwin was missing at least one crucial link in his chain of evidence - he had no evidence for contemporary evolution through natural selection. Indeed, as one commentator noted on the centenary of the publication of Origin, "Had Darwin observed industrial melanism he would have seen evolution occurring not in thousands of years but in thousands of days - well within his lifetime. He would have witnessed the consummation and confirmation of his life's work"[2].

    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.

    2008-01-01

    Objectives To implement and evaluate an innovative approach to a pharmacy seminar course intended to develop students' presentation skills and encourage them to think critically about contemporary pharmacy issues. Design The instructor provided lectures intended to prepare students for their presentations. These lectures included tips on writing abstracts, learning objectives, use of visual aids, and presentation delivery. Pairs of students chose a pharmacy issue, researched their topic including identifying various strengths of evidence to support a perspective, wrote an abstract and learning objectives, prepared their visual aids, and delivered a pro/con perspective. Students also provided peer evaluations for these presentations. A personal response system was used to provide class input on the presentations. Assessment Ninety-five percent of the peer evaluations of the presentations were good to excellent. The overall course evaluations indicated achievement of course goals. Conclusions A pharmacy seminar course intended to develop student presentation skills and critical thinking about contemporary pharmacy issues was demonstrated to be successful. The “taking sides” format was an effective design for accomplishing these objectives. PMID:18483598

  9. 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.

    2011-01-01

    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.

  11. 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.

    2014-08-01

    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

  13. 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.

    An active microbial assemblage cycles sulfur in a sulfate-rich, ancient marine brine beneath Taylor Glacier, an outlet glacier of the East Antarctic Ice Sheet, with Fe(III) serving as the terminal electron acceptor. Isotopic measurements of sulfate, water, carbonate, and ferrous iron and functional gene analyses of adenosine 5'-phosphosulfate reductase imply that a microbial consortium facilitates a catalytic sulfur cycle. These metabolic pathways result from a limited organic carbon supply because of the absence of contemporary photosynthesis, yielding a subglacial ferrous brine that is anoxic but not sulfidic. Coupled biogeochemical processes below the glacier enable subglacial microbes to grow in extended isolation, demonstrating how analogous organic-starved systems, such as Neoproterozoic oceans, accumulated Fe(II) despite the presence of an active sulfur cycle.

  15. Digoxin: its role in contemporary medicine.

    Stucky, Marcelle A; Goldberger, Zachary D

    2015-09-01

    Digoxin has been a key therapeutic for heart failure and atrial tachyarrhythmias for over 200 years following Withering's groundbreaking work depicting the therapeutic benefit of the common botanical foxglove in his 1785 monograph. The use of digoxin preceded any randomised evidence or even basic understanding of its mechanism of action. Over the past two decades, there has been mounting evidence further challenging the safety and efficacy of digoxin, while multiple other therapies for both heart failure and atrial tachyarrhythmias have proven to be more effective and safe. Altogether, digoxin still has an important role in contemporary pharmacotherapeutics, though its role remains controversial and should be reserved for selective patients and clinical situations, with careful attention to serum concentrations.

    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.

    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.

    2016-01-01

    Virginia Satir continues to be a highly influential figure in family therapy. The summation of her decades of work with families, the Satir growth model (SGM), remains a relevant therapeutic approach that is still practiced by many. This narrative review sought to examine (a) the core therapeutic methods developed by Satir for working with families, and (b) the empirical evidence to support the use of such methods. The author reviewed both firsthand and secondhand accounts of Satir's model of therapy, as well as extant research. Results from four included studies lend equivocal support for the continued use of Satir's approaches in contemporary family therapy. Implications for clinicians include the need for further refinement and systematization of the SGM. Also, researchers must empirically test Satir's methods using stronger methodology with larger and more diverse samples. In an age where evidence-based practice has become standard, all stakeholders must actively work to bolster the support for Virginia Satir's work, lest her important contributions to family therapy be forgotten due to insufficient evidence.

    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.

    2015-10-01

    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.

  14. [Thoughts on demographic optimization in contemporary Poland].

    PubMed

    Oledzki, M

    1980-01-01

    This article presents the viewpoint of the Polish school of social policy of the Institute of Social Economy concerning the problem of optimization of demographic structures and processes in contemporary Poland. This school was created under the leadership of the outstanding sociologist Ludwik Krzywicki (1859-1941). The reasoning concerns, first of all, the scientific premises of the choice of criteria of demographic optimization examined and then there is a critical assessment of modern simplified approaches to the definition of optimum population. It also shows actual possibilities of demographic optimization and the complexity of analytical categories of socioeconomic processes which determine the development of the population in specific time and space. In conclusion, the theory of demographic optimization is regarded as a task too ambitious and perhaps even utopian in view of the assumptions needed for its satisfactory realization. This conclusion confirms the thesis contained in the handbook of demography by J.Z. Holzer published in 1970. The author considers, however, that the search for a theory of demographic optimization is still a task which mobilizes social sciences to an integration centered on demography and social policy.

    Aim: The purpose of this paper is to review the literature on the clinical effectiveness of contemporary resin-based dentin bonding agents primarily focussing on the longevity of restoration. Materials and Methods: The literature published from June 2004 up to September 2010 was reviewed for clinical trials that tested the effectiveness of dentin bonding agents in the longevity of noncarious class V restoration. Results of each study reported using the USPHS criteria for clinical assessment of restoration were included and tabulated. The American Dental Association guidelines for dentin and enamel adhesives were used as a reference to compare the performance of individual bonding agents. Kruskal–Wallis followed by Mann–Whitney U was done to compare the mean Alfa score percentage for the three categories of bonding systems [etch-and-rinse (ER), self-etch primer (SEP), and self-etch-adhesive (SEA)]. Results: A comparison of the mean Alfa score percentages revealed no difference between the ER, SEP, and SEA categories of bonding systems except for marginal adaptation where ER was found to be superior to SEA. Conclusion: The clinical effectiveness of resin-based bonding agents is comparable among the three categories. PMID:21217944

    History and astronomy can be brought to bear on problems in contemporary geophysics. From seemingly crude ancient and medieval observations of eclipses, we show that variations in the length of the day can be traced back over the past 2500 years. The tidal torque exerted by the Moon (and, to a lesser extent, by the Sun) is the dominant mechanism in reducing the Earth's spin. It is known that by this mechanism, the length of the day is increasing by .- 1 + 2 3ms per century (mscy ). By analysing observations of eclipses, we find the actual measured change in the length of the day to be + 1.7mscy , from which we conclude that besides the tidal contribution, there is another long-term component acting to reduce - 1 the length of the day by- 0.6mscy . This component, which is thought to result from the decrease in the Earth's oblateness following the last Ice Age, is consistent with recent measurements made by artificial satellites. - 1

  17. Music and Astronomy: Historical and Contemporary Perspectives

    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.

  18. 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.

  19. Growing pains: contemporary knowledge and recommended practice

    Background Leg pain in children, described as growing pains, is a frequent clinical presentation seen by an array of health care professionals. Described since 1823, growing pains continues to puzzle practitioners, yet diagnostic criteria and evidence based treatment is available. Methods The medical literature has been searched exhaustively to access all articles (English language) pertaining to leg pains in children which are ascribed to being 'growing pains'. Results The literature, whilst plentiful in quantity and spanning two centuries, is generally replete with reiterated opinion and anecdote and lacking in scientific rigour. The author searched 45 articles for relevance, determined according to title, abstract and full text, resulting in a yield of 22 original studies and 23 review articles. From the original studies, one small (non-blinded) randomised controlled trial that focused on GP treatment with leg muscle stretching was found. Nine prevalence studies were found revealing disparate estimates. Ten cohort (some case-controlled) studies, which investigated pain attribute differences in affected versus unaffected groups, were found. One series of single case experiment designs and one animal model study were found. Conclusion Growing pains is prevalent in young children, presents frequently in the health care setting where it is poorly managed and is continuing to be researched. A common childhood complaint, growing pains needs to be acknowledged and better managed in the contemporary medical setting. PMID:18822152

    BACKGROUND The Fifth Evian Annual Reproduction (EVAR) Workshop Meeting discussed knowledge regarding contemporary genetics in female reproduction. METHODS Specialist reproductive medicine clinicians and geneticists delivered presentations based on published literature and current research. The content of this report is based on the expert presentations and subsequent group discussions that took place during this Workshop. RESULTS Numerous ovarian genes with a role in infertility have been identified. Future challenges for genetic screening of patients, such as those with polycystic ovary syndrome, primary ovarian insufficiency or endometriosis, include the identification of high-throughput strategies and how to apply these findings to infertile patients. The identification of high-quality embryos in IVF using objective technologies remains a high priority in order to facilitate single-embryo transfer. Gene expression profiling of cumulus cells surrounding the oocyte, and proteomic and metabolomic approaches in embryo culture media may significantly improve non-invasive embryo quality assessment. CONCLUSIONS The way forward in advancing the knowledge of genes involved in reproduction was considered to be through genome-wide association studies involving large numbers of patients. Establishing international collaboration is required to enable the application of such technologies in sufficient numbers of patients. PMID:21896560

    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.

    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.

  3. Benefits of Greenery in Contemporary City

    2016-10-01

    Greenery has always played an important role in the construction of cities. The need for green spaces has been present at city level since ancient times. However, the description of the evolutionary process of form and function of urban green spaces as it has developed from antiquity depends greatly upon the different roles played by these places throughout history. Nowadays, given that the main part of the world population is living in cities, it can be said that greenery has a strategic importance in the contemporary urban fabric. Therefore, urban design solutions should always consider both buildings and vegetation as being defining city's elements. However, the city is currently dominated by building structures which are detrimental to green spaces, causing problems of congestion and pollution. The most recent and compulsory Portuguese urban rehabilitation principles emphasize the improvement of sustainability. It is, therefore, critical to draw attention to this area and find innovative solutions in this domain, especially with regards the integration of vegetation in historical areas. In this sense, this research aims to present an approach about the importance of greenery in cities, referring some examples of green spaces as landmarks in the urban historiography. It is also focused on the benefits of green spaces in dense urban areas and their contribution for the sustainability of the cities.

  4. 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.

    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.

    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.

    A comparison of Upper Palaeolithic and contemporary salmonid vertebrae from the Iberian Peninsula indicates that there has been a significant decrease in the mean body size for a given age among Atlantic salmon and brown trout inhabiting the southernmost range of their endemic distribution. Mean size at age was greater in prehistoric specimens for all age classes during the freshwater phase of their life histories. Fisheries-induced evolution (selection for smaller sizes) is an obvious explanation for the observed reduction in fish body size, but recent changes in the aquatic habitat affecting density-dependent growth cannot be ruled out.

    1996-01-01

    Unprecedented advances in the natural sciences and in medical technology bring many moral issues unknown to previous generations. Very often in their medical practice physicians face problems in which the basic role is played by moral commitment. In this context, a set of qualitatively new questions emerges: Should we continue medical treatment when the patient asks that it be discontinued? Must we preserve the life of the irreversibly comatose patients? How to assess moral aspects of various forms of donating organs for transplants in evolving social-cultural situation? Does any religion provide a definition of biological death that would be inconsistent with the definition provided by the medical sciences? To answer such ethical questions that emerge in our evolving culture, there is an urgent need for interdisciplinary discussions developed by scientists, philosophers, and theologians. In a philosophically justified attitude of Christian personalism, any life has an unique value, though it cannot be regarded as an absolutely highest value (The Catechism of the Catholic Church, p. 2289). The donation of the organs should be regarded as an act of love. To be an act of human person, the decision of donation should be expressed in a free and deliberate, manne. In this perspective, the principle of the presumed consent is assessed critically because it implies hierarchy of values in which pure pragmatism is appreciated more than the love to our neighbours (The Catechism... p. 2296). Certainly, the standpoint of pragmatism as such must not be assessed negatively; the sacredness of life, its dignity, God-dependence and objective value cannot be, however, adequately expressed in purely pragmatic terms. The latter categories are basic also in providing Christman answer to may ethical questions raised in contemporary medical sciences.

  13. Contemporary Science and Worldview-Making

    NASA Astrophysics Data System (ADS)

    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 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.

  16. The Contemporary Hazard of Cometary Impacts

    NASA Technical Reports Server (NTRS)

    Morrison, David

    1994-01-01

    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.

  17. Population changes: contemporary models and theories.

    PubMed

    Sauvy, A

    1981-01-01

    In many developing countries rapid population growth has promoted a renewed interest in the study of the effect of population growth on economic development. This research takes either the macroeconomic viewpoint, where the nation is the framework, or the microeconomic perspective, where the family is the framework. For expository purposes, the macroeconomic viewpoint is assumed, and an example of such an investment is presented. Attention is directed to the following: a simplified model--housing; the lessons learned from experience (primitive populations, Spain in the 17th and 18th centuries, comparing development in Spain and Italy, 19th century Western Europe, and underdeveloped countries); the positive factors of population growth; and the concept of the optimal rate of growth. Housing is the typical investment that an individual makes. Hence, the housing per person (roughly 1/3 of the necessary amount of housing per family) is taken as a unit, and the calculations are made using averages. The conclusion is that growth is expensive. A population decrease might be advantageous, for this decrease would enable the entire population to benefit from past capital accumulation. It is also believed, "a priori," that population growth is more expensive for a developed than for a developing country. This belief may be attributable to the fact that the capital per person tends to be high in the developed countries. Any further increase in the population requires additional capital investments, driving this ratio even higher. Yet, investment is not the only factor inhibiting economic development. The literature describes factors regarding population growth, yet this writer prefers to emphasize 2 other factors that have been the subject of less study: a growing population's ease of adaptation and the human factor--behavior. A growing population adapts better to new conditions than does a stationary or declining population, and contrary to "a priori" belief, a growing

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

    PubMed

    de Chadarevian, Soraya

    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.

    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.

  3. 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

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

    PubMed

    Xiong, Huan

    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.

  5. Subhealth: questioning the quality of bodies in contemporary China.

    PubMed

    Bunkenborg, Mikkel

    2014-01-01

    In this article, I explore contemporary medical and popular discourse on subhealth (yajiankang) in China. The idea that most people suffer from subhealth was at first associated with the marketing of a health product in the 1990 s, but subhealth acquired new meanings when it was popularized in media reports of sudden death and it gradually became a field of medical research. Subhealth discourse revolves around bodies characterized by lack and need of improvement, and thus it mirrors the governmental concern with lack of quality (suzhi) that has figured prominently in contemporary anthropological writings on China. The widespread concern with subhealth, however, suggests that the health care industry has significant influence on the way bodies are imagined and acted upon, and I argue that anthropological research on processes of subject formation in contemporary China might be enriched by looking beyond the state and exploring the field of liberalized health care ethnographically.

  6. Historic land use influences contemporary establishment of invasive plant species.

    The legacy of agricultural land use can have widespread and persistent effects on contemporary landscapes. Although agriculture can lead to persistent changes in soil characteristics and plant communities, it remains unclear whether historic agricultural land use can alter the likelihood of contemporary biological invasions. To understand how agricultural land-use history might interact with well-known drivers of invasion, we conducted factorial manipulations of soil disturbance and resource additions within non-agricultural remnant sites and post-agricultural sites invaded by two non-native Lespedeza species. Our results reveal that variation in invader success can depend on the interplay of historic land use and contemporary processes: for both Lespedeza species, establishment was greater in remnant sites, but soil disturbance enhanced establishment irrespective of land-use history, demonstrating that contemporary processes can help to overcome legacy constraints on invader success. In contrast, additions of resources known to facilitate seedling recruitment (N and water) reduced invader establishment in post-agricultural but not in remnant sites, providing evidence that interactions between historic and contemporary processes can also limit invader success. Our findings thus illustrate that a consideration of historic land use may help to clarify the often contingent responses of invasive plants to known determinants of invasibility. Moreover, in finding significantly greater soil compaction at post-agricultural sites, our study provides a putative mechanism for historic land-use effects on contemporary invasive plant establishment. Our work suggests that an understanding of invasion dynamics requires knowledge of anthropogenic events that often occur decades before the introduction of invasive propagules.

    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 dines. 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 needed

    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.

    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.

    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.

    2016-01-01

    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

    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

    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.

    The clinical use of information technology in the dental profession has increased substantially in the past 10 to 20 years. In most developing countries an insufficiency of medical and dental specialists has increased the mortality of patients suffering from various diseases. Employing technology, especially artificial intelligence technology, in medical and dental application could reduce cost, time, human expertise and medical error. This approach has the potential to revolutionise the dental public health scenario in developing countries. Clinical decision support systems (CDSS) are computer programs that are designed to provide expert support for health professionals. The applications in dental sciences vary from dental emergencies to differential diagnosis of orofacial pain, radiographic interpretations, analysis of facial growth in orthodontia to prosthetic dentistry. However, despite the recognised need for CDSS, the implementation of these systems has been limited and slow. This can be attributed to lack of formal evaluation of the systems, challenges in developing standard representations, cost and practitioner scepticism about the value and feasibility of CDSS. Increasing public awareness of safety and quality has accelerated the adoption of generic knowledge based CDSS. Information technology applications for dental practice continue to develop rapidly and will hopefully contribute to reduce the morbidity and mortality of oral and maxillofacial diseases and in turn impact patient care.

    2006-12-01

    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.

  17. 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.

    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.

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

    PubMed

    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.

    Rudan, Dusko; Jakovljevic, Miro; Marcinko, Darko

    2016-12-01

    The article discusses the impact of contemporary culture on the individual's personality. We used the "psychocultural" approach whose key feature is the amalgamation of theories and methods belonging to psychodynamic and psychosocial studies, as well as those used in the field of media and cultural studies. The idea of a potentially therapeutic effect of culture (therapy culture) can already been seen in Freud's and Lacan's texts, and it is often used in critical analyses of contemporary corporate culture, which is more or less developed in some parts of the world. In their criticisms, many contemporary authors emphasize that modern societies have a tendency towards the weakening of basic commitment, or lack thereof, to a social equivalent of Winnicott's concept of environmental provisions as an inalienable democratic right essential for human emotional and mental progress or emotional well-being. The article describes frequent resorting to the so-called manic defences that defensively distort, deny and obscure the awareness that a human being is not the omnipotent source of life, but instead depends on other human beings, and often tries to compensate for loss through various activities. The article describes excessive shopping as an activity that often serves as an attempt to find what was lost, i.e. to fill an emotional void. This solution (resorting to manic defences) is encouraged by contemporary culture, especially through promotional material (e.g. advertising). The main theses of this article are supported by quotations and data from world literature.

  3. Thinking in action: thought made visible in contemporary dance.

    PubMed

    Stevens, Catherine; McKechnie, Shirley

    2005-12-01

    Contemporary dance-movement deliberately and systematically cultivated for its own sake-is examined in the light of the procedural and declarative view of long-term knowledge. We begin with a description of two settings in which new works of contemporary dance are created and performed. Although non-verbal, contemporary dance can be a language declared through movement and stillness of the body. Ideas for new movement material come from objects, events or imaginings that are spoken, seen, heard, imagined, or felt. Declared through movement, the idea becomes visible. Communication in dance involves general psychological processes such as direct visual perception of motion and force, motor simulation via mirror neurons, and implicit learning of movement vocabularies and grammars. Creating and performing dance appear to involve both procedural and declarative knowledge. The latter includes the role of episodic memory in performance and occasional labelling of movement phrases and sections in rehearsal. Procedural knowledge in dance is augmented by expressive nuance, feeling and communicative intent that is not characteristic of other movement-based procedural tasks. Having delineated lexical and grammatical components in dance, neural mechanisms are identified based on Ullman's (Ullman in Cognition 92:231-270, 2004) alignment of lexical knowledge with declarative memory and mental grammar with procedural memory. We conclude with suggestions for experiments to test these assumptions that concern thought in action in composition, performance and appreciation of contemporary dance.

  1. The oblique perspective: philosophical diagnostics of contemporary life sciences research.

    PubMed

    Zwart, Hub

    2017-12-01

    This paper indicates how continental philosophy may contribute to a diagnostics of contemporary life sciences research, as part of a "diagnostics of the present" (envisioned by continental thinkers, from Hegel up to Foucault). First, I describe (as a "practicing" philosopher) various options for an oblique (or symptomatic) reading of emerging scientific discourse, bent on uncovering the basic "philosophemes" of science (i.e. the guiding ideas, the basic conceptions of nature, life and technology at work in contemporary life sciences research practices). Subsequently, I outline a number of radical transformations occurring both at the object-pole and at the subject-pole of the current knowledge relationship, namely the technification of the object and the anonymisation or collectivisation of the subject, under the sway of automation, ICT and big machines. Finally, I further elaborate the specificity of the oblique perspective with the help of Lacan's theorem of the four discourses. Philosophical reflections on contemporary life sciences concur neither with a Master's discourse (which aims to strengthen the legitimacy and credibility of canonical sources), nor with university discourse (which aims to establish professional expertise), nor with what Lacan refers to as hysterical discourse (which aims to challenge representatives of the power establishment), but rather with the discourse of the analyst, listening with evenly-poised attention to the scientific files in order to bring to the fore the cupido sciendi (i.e. the will to know, but also to optimise and to control) which both inspires and disrupts contemporary life sciences discourse.

  9. 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.

    1998-03-01

    The contemporary women's movement in India (1975-present) has played an important role in bringing gender issues to the forefront of development planning and defining feminist politics. This paper examines how this movement has addressed the issue of women's education. The first section highlights contributions of the social reformist movement in the 19th century and the nationalist movement in promoting women's education. The role of the contemporary women's movement in changing school curricula is examined in the second section, followed by discussion on how women's studies has contributed to redefining knowledge. The fourth section discusses women's empowerment and education from the perspective of the women's movement. The article concludes by highlighting challenges facing the women's movement in promoting women's education for equality and empowerment.

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

    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.

  20. Gaps and spaces: representations of dementia in contemporary British poetry.

    PubMed

    Zeilig, Hannah

    2014-03-01

    This article considers the work of a number of contemporary British poets who have attempted to articulate some of the experiences that dementia entails. The unique potential of poetry as a means of portraying the dislocations and reinventions of self that dementia involves has been mostly overlooked. The insights offered by critical gerontology are central to this article. This perspective calls for critical thought about the ways in which dementia has been socially constructed. The challenges posed by poets such as Vuyelwa Carlin, Valerie Laws and Jo Shapcott in particular, are examined. The complex poetic representations offered by these poets acknowledge the pathological declines of dementia and simultaneously celebrate the individuality and life of their subjects. Considering dementia with reference to the work of contemporary poets and critical gerontology is one way in which we can deepen our understanding of what this illness involves and humanise those who suffer from it.

    2013-01-01

    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.

    A case study on a contemporary Indian miniature was carried out through the application of different spectroscopic techniques. Painting support, pigments, and dyes were largely characterized by means of energy dispersive x-ray fluorescence and Raman microspectroscopy directly on the artwork. Regarding golden motifs and silvered areas, for which these techniques have not provided enough information, scanning electron microscopy coupled with energy dispersive x-ray spectroscopy was used as a complementary technique. The painting support was identified as the Bombyx mori silk. Among the colorant matters, several pigments were identified such as chrome yellow, lithopone, hematite, lamp black, mica-titania pearlescent pigment, and tin-based metallic silver, and dyes such as phthalocyanine blue and the recent synthetic pigment red PR9 naphthol AS. All this materials will provide evidence in the support of the contemporary production of the artwork for future studies.

  3. Defenses and morality: Adam Smith, Sigmund Freud, and contemporary psychoanalysis.

    PubMed

    Gabrinetti, Paul A; Özler, Sule

    2014-10-01

    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.

  4. 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.

  5. Clinical Growth: An Evolutionary Concept Analysis.

    PubMed

    Barkimer, Jessica

    2016-01-01

    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.

    Fascination with the interworkings of the human body has permeated scientific discovery for eons. Materials for dissection proved problematic for anatomists. Andreas Vesalius solved his dilemma by visiting local gallows where criminals had been executed. Eduard Pernkopf has been alleged to have taken some of his materials from victims of the Holocaust. Even today, executed criminals have served as subjects for anatomical educational purposes. These circumstances are explored and the contemporary ethics of each are compared.

  7. 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.

  8. Contemporary Evolutionary Divergence for a Protected Species following Assisted Colonization

    2011-01-01

    Background Contemporary evolution following assisted colonization may increase the probability of persistence for refuge populations established as a bet-hedge for protected species. Such refuge populations are considered “genetic replicates” that might be used for future re-colonization in the event of a catastrophe in the native site. Although maladaptive evolutionary divergence of captive populations is well recognized, evolutionary divergence of wild refuge populations may also occur on contemporary time scales. Thus, refuge populations may lose their “value” as true genetic replicates of the native population. Here, we show contemporary evolutionary divergence in body shape in an approximately 30-year old refuge population of the protected White Sands pupfish (Cyprinodon tularosa) resulting in a body-shape mismatch with its native environment. Methodology/Principal Findings Geometric morphometic data were collected from C. tularosa cultures raised in experimental mesocosms. Cultures were initiated with fish from the two native populations, plus hybrids, in high or low salinity treatments representing the salinities of the two native habitats. We found that body shape was heritable and that shape variation due to phenotypic plasticity was small compared to shape variation due to population source. C. tularosa from the high salinity population retained slender body shapes and fish from the low salinity population retained deep body shapes, irrespective of mesocosm salinity. These data suggest that the observed divergence of a recently established pupfish population was not explained by plasticity. An analysis of microsatellite variation indicated that no significant genetic drift occurred in the refuge population, further supporting the adaptive nature of changes in body shape. These lines of evidence suggest that body shape divergence of the refuge population reflects a case of contemporary evolution (over a 30-year period). Conclusions

    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.

  11. 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.

    Critical limb ischemia (CLI) remains a significant cause of morbidity and mortality in patients with peripheral arterial disease. Optimal treatment strategies for CLI remain controversial. The only randomized trial comparing surgical with endovascular revascularization suggests no significant difference in limb salvage between open surgical bypass and angioplasty. Although novel endovascular strategies are now available, their efficacies remain largely untested in a randomized fashion. This review provides an overview of the data surrounding contemporary outcomes of endovascular therapy with an emphasis on current knowledge gaps.

  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

    1999-01-01

    This paper advances three claims. First, according to contemporary Western advocates of physician-assisted suicide and voluntary euthanasia, "death with dignity" is understood negatively as bringing about death to avoid or prevent indignity, that is, to avoid a degrading existence. Second, there is a similar morally affirmative view on death with dignity in ancient China, in classical Confucianism in particular. Third, there is a consonance as well as dissonance between these two ethics of death with dignity, such as that the Confucian perspective would regard the argument for physician-assisted suicide and voluntary euthanasia as less than compelling because of the latter's impoverished vision of human life.

    2013-01-01

    In 1692 and 1693, in Salem, Massachusetts, more than 150 colonists were accused of witchcraft, resulting in 19 being hanged and one man being crushed to death. Contributions to these events included: historical, religious and cultural belief systems; social and community concerns; economic, gender, and political factors; and local family grievances. Child witnessing, certainty of physician diagnosis, use of special evidence in the absence of scholarly and legal scrutiny, and tautological reasoning were important factors, as well. For forensic psychiatry, the events at Salem in 1692 still hold contemporary implications. These events of three centuries ago call to mind more recent daycare sexual abuse scandals.

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.

  6. 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.

    Measuring population connectivity is a critical task in conservation biology. While genetic markers can provide reliable long-term historical estimates of population connectivity, scientists are still limited in their ability to determine contemporary patterns of gene flow, the most practical time frame for management. Here, we tackled this issue by developing a new approach that only requires juvenile sampling at a single time period. To demonstrate the usefulness of our method, we used the Speartooth shark (Glyphis glyphis), a critically endangered species of river shark found only in tropical northern Australia and southern Papua New Guinea. Contemporary adult and juvenile shark movements, estimated with the spatial distribution of kin pairs across and within three river systems, was contrasted with historical long-term connectivity patterns, estimated from mitogenomes and genome-wide SNP data. We found strong support for river fidelity in juveniles with the within-cohort relationship analysis. Male breeding movements were highlighted with the cross-cohort relationship analysis, and female reproductive philopatry to the river systems was revealed by the mitogenomic analysis. We show that accounting for juvenile river fidelity and female philopatry is important in population structure analysis and that targeted sampling in nurseries and juvenile aggregations should be included in the genomic toolbox of threatened species management.

  8. Contemporary doming of the Adirondack mountains: Further evidence from releveling

    USGS Publications Warehouse

    Isachsen, Y.W.

    1981-01-01

    The Adirondack Mountains constitute an anomalously large, domical uplift on the Appalachian foreland. The dome has a NNE-SSW axis about 190 km long, and an east-west dimension of about 140 km. It has a structural relief of at least 1600 m, and a local topographic relief of up to 1200 m. First-order leveling in 1955, and again in 1973 along a north-south line at the eastern margin of the Adirondack shows an uplift rate of 2.2 mm/yr at the latitude of the center of the dome and a subsidence rate of 2.8 mm/yr at the northern end of the line near the Canadian border. The net amount of arching along this releveled line is 9 cm ?? 2 cm (Isachsen, 1975). To test the idea that this arching represented an "edge effect" of contemporary doming of the Adirondacks as a whole, the National Geodetic Survey was encouraged to relevel a 1931 north-south line between Utica and Fort Covington (near the Canadian border) which crosses the center of the dome. The releveling showed that the mountain mass is undergoing contemporary domical uplift at a rate which reaches 3.7 mm/yr near the center of the dome (compare with 1 mm/yr for the Swiss Alps). Three other releveled lines in the area support this conclusion. ?? 1981.

  9. 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.

  10. Slide track analysis of eight contemporary hip simulator designs.

    In an earlier paper, the authors presented a new method of computation of slide tracks in the relative motion between femoral head and acetabular cup of total hip prostheses. For the first time, computed tracks were verified experimentally and with an alternative method of computation. Besides being an efficient way to illustrate hip kinematics, the shapes of the slide tracks are known to be of fundamental importance regarding the wear behaviour of prostheses. The verified method was now applied to eight contemporary hip simulator designs. The use of correct motion waveforms and an Euler sequence of rotations in each case was again found to be essential. Considerable differences were found between the simulators. For instance, the shapes of the tracks drawn by the resultant contact force included a circle, ellipse, irregular oval, leaf, twig, and straight line. Computation of tracks correctly for the most widely used hip simulator, known as biaxial, was made possible by the insight that the device is actually three-axial. Slide track patterns have now been computed for virtually all contemporary hip simulators, and both for the heads and for the cups. This comparative analysis forms a valuable basis for studies on the relationship between the type of multidirectional motion and wear. These studies can produce useful information for the design of joint simulators, and improve the understanding of wear phenomena in prosthetic joints.

  11. Contemporary art and Hanna Segal's thinking on aesthetics.

    PubMed

    Abella, Adela

    2010-02-01

    From the point of view of the history of ideas in psychoanalysis, a major shift may be described from Freud's starting point considering art as sublimation of sexual desires on a largely objectal level to later developments emphasizing the presence in art of destructiveness and narcissistic conflicts. Segal's contribution represents a watershed in this evolution. Following Klein, Hanna Segal suggests considering art in relation to depressive anxieties and reparation in such a way that artistic activity may be seen as an attempt 'to restore and re-create the loved object outside and inside the ego' which implies a successful work of mourning accompanied by symbol formation. For Segal, these reparative processes are conveyed through formal beauty which represents the victory of reparation over destruction. Nevertheless, contemporary art demands that we consider the intervention, in art, of more raw and less symbolized/sublimated processes, including acting-out in often primitive, psychotic or perverse ways. Thus this paper unfolds in two directions: on the one hand, it examines the differences and continuities between Freud's and Segal's thinking whilst, on the other, the author presents some alternative ideas which stress the search for truth and new thinking in contemporary art.

  12. Measurements and modeling of contemporary radiocarbon in the stratosphere

    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.

  13. Eating disorders and attachment: a contemporary psychodynamic perspective.

    PubMed

    Tasca, Giorgio A; Balfour, Louise

    2014-06-01

    A contemporary psychodynamic framework can add much to our understanding of eating disorders. Eating disorders are associated with complex comorbidities, high levels of mortality, and therapist countertransferences that can complicate psychological treatments. Mainstream models currently focus on cognitive, biological, or cultural factors to the near exclusion of attachment functioning, and the individual's dynamics. As such, standard models appear to exclude person-centred and developmental considerations when providing treatments. In this article, we describe a contemporary psychodynamic model that understands eating disorder symptoms as a consequence of vulnerability to social pressures to be thin and biological predispositions to body weight. Individual vulnerabilities are rooted in unmet attachment needs causing negative affect, and subsequent maladaptive defenses and eating disorder symptoms as a means of coping. We describe how this model can inform transdiagnostic eating disorder treatment that focuses on symptoms as well as specific attachment functions including: interpersonal style, affect regulation, reflective functioning, and coherence of mind. Two clinical examples are presented to illustrate case formulations and psychological treatments informed by these conceptualizations.

  14. 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.

    1975-01-01

    Each of fifteen scientific specialty fields was represented by a journal and the percent of "legendary" papers (those with at least one reference twenty-five or more years old) was calculated for each field. Non-legendary papers were designated as "contemporary". A historical divergence was uncovered when the highly legendary field, physiology, was compared with the highly contemporary field, microbiology, both fields being moderately contemporary in 1922. The legendary contemporary field characteristics of a field are useful for estimating libraries' requirements for back holdings and for appraising literature searches. PMID:1095096

  16. Body metaphors--reading the body in contemporary culture.

    2004-01-01

    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.

    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.

  18. Mario Bunge's Materialist Theory of Mind and Contemporary Cognitive Science

    2012-10-01

    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.

    2012-07-01

    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.

    2009-01-01

    Binge drinking is a matter of current social, political and media concern. It has a long-term, but also a recent, history. This paper discusses the contemporary history of the concept of binge drinking. In recent years there have been significant changes in how binge drinking is defined and conceptualised. Going on a ‘binge’ used to mean an extended period (days) of heavy drinking, while now it generally refers to a single drinking session leading to intoxication. We argue that the definitional change is related to the shifts in the focus of alcohol policy and alcohol science, in particular in the last two decades, and also in the role of the dominant interest groups. The paper is a case study in the relationship between science and policy. We explore key themes, raise questions and point to a possible agenda for future research.

    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.

    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.

    An overview is presented of the broad perspective of all plasma science. Detailed discussions are given of scientific opportunities in various subdisciplines of plasma science. The first subdiscipline to be discussed is the area where the contemporary applications of plasma science are the most widespread, low temperature plasma science. Opportunities for new research and technology development that have emerged as byproducts of research in magnetic and inertial fusion are then highlighted. Then follows a discussion of new opportunities in ultrafast plasma science opened up by recent developments in laser and particle beam technology. Next, research that uses smaller scale facilities is discussed, first discussing non-neutral plasmas, and then the area of basic plasma experiments. Discussions of analytic theory and computational plasma physics and of space and astrophysical plasma physics are then presented.

    2003-12-01

    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.

    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.

    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

    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.

    Adult congenital aortic coarctation is an entity rarely seen in clinical practice. It is commonly diagnosed and managed in the early stages of life, mean in the neo-natal or young children's ages. Some cases however can be overlooked at this scrutinity and become recognizable at later stages, in adulthood, through symptoms and signs resulting from the deep hemodynamic deregulation caused by the disease in the proximal and distal aortic physiology, requiring often imperative therapeutic repair. In this paper, an extensive revision is made on the main pathologic, clinical and diagnostic features of the disease, culminating in a critical analysis on the contemporary therapeutic methods available, which includes the conventional open surgery and the endovascular intervention, which includes the balloon angioplasty, the stenting and the covered stents.

    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

    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.

    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.

    While most global productivity is driven by modern photosynthesis, river ecosystems are supplied by locally fixed and imported carbon that spans a range of ages. Alluvial aquifers of gravel-bedded river floodplains present a conundrum: despite no possibility for photosynthesis in groundwater and extreme paucity of labile organic carbon, they support diverse and abundant large-bodied consumers (stoneflies, Insecta: Plecoptera). Here we show that up to a majority of the biomass carbon composition of these top consumers in four floodplain aquifers of Montana and Washington is methane-derived. The methane carbon ranges in age from modern to up to >50,000 years old and is mostly derived from biogenic sources, although a thermogenic contribution could not be excluded. We document one of the most expansive ecosystems to contain site-wide macroinvertebrate biomass comprised of methane-derived carbon and thereby advance contemporary understanding of basal resources supporting riverine productivity.

    2014-06-01

    ICU readmissions are a commonly used quality measure but despite decades of research, these adverse events continue to occur. Of particular concern is that readmitted patients have much worse prognoses than those not readmitted. In recent years new clinical service roles have evolved to assist ward staff with the care of acutely ill patients, such as those discharged from ICU. Given the recent emergence of these service roles, a review of contemporary ICU readmission studies was warranted to determine their impact on this adverse event. Reviewed studies indicated the incidence of readmissions and outcomes of these patients have changed little in recent years. Few studies mentioned whether clinical service roles existed to support ward staff caring for patients recently discharged from ICU. Future research needs to focus on identifying modifiable factors in care processes to reduce the incidence and outcomes of this adverse event and to determine how clinical service roles can best help prevent its occurrence.

    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.

    Since antiquity, biology has had two opposing views of life and organisms: holistic (organismic) and reductionist. In contemporary biology, the molecular reductionist approach prevails--its central entity being the gene. Organicism lingers on the margin of biology, having well-elaborated ideas but no empirical confirmation for the integrative biological entity. The latter could be found in the endogenous coherent EM field (ECEMF), since it organizes countless cellular processes, including cell's division, and through the coupling of coherence domains integrates the whole organism. A serious and thorough reconsideration of life and organisms in light of this new biological entity would have far-reaching consequences in all areas of biological science, i.e., in ontogeny, the theory of evolution, understanding and combating serious illnesses, and above all, cancer.

    Foreclosure rates in America reached unprecedented levels during the last half of the 2000s, and many observers have speculated that elevated crime rates were one of the probable negative collateral consequences of this trend. We examine this issue with a comprehensive county-level analysis of the role of foreclosure in shaping contemporary crime patterns, highlighting the possibility of theoretically informed non-linear and conditional relationships. Multivariate regression models that account for the well-documented spatial autocorrelation of crime rates and the possible endogeneity of foreclosure reveal a positive association between rates of foreclosure and property crime that accelerates significantly once foreclosure rates attain historically high levels. Multiplicative models indicate that this pattern holds for burglary across diverse county conditions, but the observed non-linear effect of foreclosure on robbery rates is limited primarily to areas that also exhibit relatively high levels of resource deprivation and limited new housing construction.

  1. Ancient and methane-derived carbon subsidizes contemporary food webs

    While most global productivity is driven by modern photosynthesis, river ecosystems are supplied by locally fixed and imported carbon that spans a range of ages. Alluvial aquifers of gravel-bedded river floodplains present a conundrum: despite no possibility for photosynthesis in groundwater and extreme paucity of labile organic carbon, they support diverse and abundant large-bodied consumers (stoneflies, Insecta: Plecoptera). Here we show that up to a majority of the biomass carbon composition of these top consumers in four floodplain aquifers of Montana and Washington is methane-derived. The methane carbon ranges in age from modern to up to >50,000 years old and is mostly derived from biogenic sources, although a thermogenic contribution could not be excluded. We document one of the most expansive ecosystems to contain site-wide macroinvertebrate biomass comprised of methane-derived carbon and thereby advance contemporary understanding of basal resources supporting riverine productivity.

  2. 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.

  3. Collaboration, interdisciplinarity, and the epistemology of contemporary science.

    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.

  4. Complexity and postmodernism in contemporary theory of psychoanalytic change.

    2008-01-01

    The contemporary literature on change in psychoanalysis has struggled to integrate recent developments in theory. Reasons for its limitations are discussed. The present article brings to bear relevant concepts drawn from postmodernism and complexity theory on ideas about how change occurs in psychoanalysis. In elaborating these two skeins, it looks critically at some recent attempts to incorporate them and considers their relationship to each other. A general description of complexity theory is offered because it has not yet been well documented in the analytic literature. Postmodern theory is talked about in relation to change; it has been discussed more generally in the author's earlier work. Ways in which postmodernism and complexity theory can inform psychoanalysis but also constrain some of its assumptions are explored. The nature and occurrence of qualitative events of psychoanalytic change are described. Four kinds of such events are described and illustrated with clinical vignettes. Analytic change viewed from a macro rather than a micro level is also discussed.

    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.

  6. 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.

    Contemporary evolution through human-induced hybridization occurs throughout the taxonomic range. Formerly allopatric species appear especially susceptible to hybridization. Consequently, hybridization is expected to be more common in regions with recent sympatry owing to human activity than in areas of historical range overlap. Coyotes (Canis latrans) and gray wolves (C. lupus) are historically sympatric in western North America. Following European settlement gray wolf range contracted, whereas coyote range expanded to include eastern North America. Furthermore, wolves with New World (NW) mitochondrial DNA (mtDNA) haplotypes now extend from Manitoba to Québec in Canada and hybridize with gray wolves and coyotes. Using mtDNA and 12 microsatellite markers, we evaluated levels of wolf-coyote hybridization in regions where coyotes were present (the Canadian Prairies, n = 109 samples) and absent historically (Québec, n = 154). Wolves with NW mtDNA extended from central Saskatchewan (51°N, 69°W) to northeastern Québec (54°N, 108°W). On the Prairies, 6.3% of coyotes and 9.2% of wolves had genetic profiles suggesting wolf-coyote hybridization. In contrast, 12.6% of coyotes and 37.4% of wolves in Québec had profiles indicating hybrid origin. Wolves with NW and Old World (C. lupus) mtDNA appear to form integrated populations in both regions. Our results suggest that hybridization is more frequent in historically allopatric populations. Range shifts, now expected across taxa following climate change and other human influence on the environment, might therefore promote contemporary evolution by hybridization.

    Objective: The phenomenal popularity of social networking sites has been used globally by medical professionals to boost professional associations and scientific developments. They have tremendous potential to forge professional liaisons, generate employment,upgrading skills and publicizing scientific achievements. We highlight the role of social networking mediums in influencing teaching, training and research in anaesthesiology. Background: The growth of social networking sites have been prompted by the limitations of previous facilities in terms of ease of data and interface sharing and the amalgamation of audio visual aids on common platforms in the newer facilities. Review: Contemporary social networking sites like Facebook, Twitter, Tumblr,Linkedn etc and their respective features based on anaesthesiology training or practice have been discussed. A host of advantages which these sites confer are also discussed. Likewise the potential pitfalls and drawbacks of these facilities have also been addressed. Conclusion: Social networking sites have immense potential for development of training and research in Anaesthesiology. However responsible and cautious utilization is advocated. PMID:27625491

    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 CO2 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.

  6. Countercurrents from the West: “blue-eyed” Zen masters, Vipassanā meditation, and Buddhist psychotherapy in contemporary Korea.

    2011-01-01

    One surprising and yet relatively unknown aspect of contemporary Korean Buddhism is the significant influence of American and European Buddhism. Between 1989 and 2009, South Koreans witnessed well-educated “blue-eyed” monastic residents via the Korean media, and the emergence of new bestsellers by authors like Thich Nhat Hahn and Jack Kornfield, written initially for Western audiences but since translated into Korean. The new teachings from the West have inspired a sudden growth of interest in vipassanā meditation as an “alternative” to Kanhwa Sŏn practice, and the emergence of a new academic field: Buddhist psychotherapy. This new wave of transnational influence from the West has changed not only the way Koreans practice Buddhism but also how they perceive Buddhist history and their own identities. In addition, the perceived “prestige” of Buddhism in the West has provided a new rhetorical strategy to defend Buddhism against other religions, particularly Korean evangelical Christianity.

  7. Regional hydro-climatic impacts of contemporary Amazonian deforestation

    NASA Astrophysics Data System (ADS)

    Khanna, Jaya

    More than 17% of the Amazon rainforest has been cleared in the past three decades triggering important climatological and societal impacts. This thesis is devoted to identifying and explaining the regional hydroclimatic impacts of this change employing multidecadal satellite observations and numerical simulations providing an integrated perspective on this topic. The climatological nature of this study motivated the implementation and application of a cloud detection technique to a new geostationary satellite dataset. The resulting sub daily, high spatial resolution, multidecadal time series facilitated the detection of trends and variability in deforestation triggered cloud cover changes. The analysis was complemented by satellite precipitation, reanalysis and ground based datasets and attribution with the variable resolution Ocean-Land-Atmosphere-Model. Contemporary Amazonian deforestation affects spatial scales of hundreds of kilometers. But, unlike the well-studied impacts of a few kilometers scale deforestation, the climatic response to contemporary, large scale deforestation is neither well observed nor well understood. Employing satellite datasets, this thesis shows a transition in the regional hydroclimate accompanying increasing scales of deforestation, with downwind deforested regions receiving 25% more and upwind deforested regions receiving 25% less precipitation from the deforested area mean. Simulations robustly reproduce these shifts when forced with increasing deforestation alone, suggesting a negligible role of large-scale decadal climate variability in causing the shifts. Furthermore, deforestation-induced surface roughness variations are found necessary to reproduce the observed spatial patterns in recent times illustrating the strong scale-sensitivity of the climatic response to Amazonian deforestation. This phenomenon, inconsequential during the wet season, is found to substantially affect the regional hydroclimate in the local dry and parts of

  8. Contemporary deformation and stressing rates in Southern Alaska

    NASA Astrophysics Data System (ADS)

    Ali, Syed Tabrez; Freed, Andrew M.

    2010-11-01

    The subduction of the Pacific Plate beneath North America induces broad scale stressing of the Alaskan crust that has led to the development of the highest mountains in North America, the highest slip rates along some of the longest strike-slip faults on Earth, and widespread seismicity that includes the 1964 M9.2 Alaska earthquake, the second largest ever recorded. These features are a consequence of deformation associated with three primary processes, interseismic loading due to relative plate motions, large earthquakes and post-seismic processes. How these mechanisms contribute to the evolution of stress in the Alaskan crust is not well understood. Here we use observed contemporary surface velocities to constrain 2-D and 3-D viscoelastic numerical models of relative Pacific/North American plate motions, coseismic slip associated with the 1964 (M9.2) megathrust event and strike-slip earthquakes on the transform boundary in 1949 (M8.1), 1958 (M7.8) and 1972 (M7.6) (the four largest events prior to the 2002 M7.9 Denali quake), viscoelastic relaxation following these events, and afterslip, to gain insight into how these processes are shaping Alaska today. Results suggest that interseismic deformation and on-going post-seismic deformation following the 1964 earthquake both contribute significantly to the GPS measured contemporary velocity field. Viscoelastic relaxation associated with a mantle with a viscosity of ~1019 Pa s is required to explain southerly directed velocities that are observed in the Cook Inlet region to well north of the Denali fault. Results also suggest that subduction of the Pacific Plate leads to a broad zone of deformation with high stressing rates concentrated in a band that lies several hundred kilometres from the plate boundary, coeval with the inboard location of the maximum locking depth of the megathrust. Interseismic deformation and stressing rates remain high further inland across the Yakutat microplate, where flat subduction extends

    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

    Six discriminant functions, developed from an historic White population, were tested on a contemporary White population for determination of sex from the hyoid. One hundred and thirty four fused and unfused hyoids from a contemporary White population were used. Individuals ranged between 20 and 49 years old. Six historic White discriminant functions were applied to the fused and unfused hyoids of the pooled contemporary White population, i.e. all males and females and all age ranges combined. The overall accuracy rates were between 72.1% and 92.3%. Correct sex determination for contemporary White males ranged between 88.2% and 96.3%, while correct sex determination for contemporary White females ranged between 31.3% and 92.0%. Discriminant functions were created for the contemporary White population with overall mean accuracy rates between 67.0% and 93.0%. The multivariate discriminant function overall accuracy rates were between 89.0% and 93.0% and the univariate discriminant function overall accuracy rates were between 67.0% and 86.8%. The contemporary White population data were compared to other populations and showed significant differences between many of the variables measured. This study illustrated the need for population-specific and temporally-specific discriminant functions for determination of sex from the hyoid bone.

    Gompertz growth curves were fitted to the data of 137 rabbits from control (C) and selected (S) lines. The animals came from a synthetic rabbit line selected for an increased growth rate. The embryos from generations 3 and 4 were frozen and thawed to be contemporary of rabbits born in generation 10. Group C was the offspring of generations 3 and 4, and group S was the contemporary offspring of generation 10. The animals were weighed individually twice a week during the first four weeks of life, and once a week thereafter, until 20 weeks of age. Subsequently, the males were weighed weekly until 40 weeks of age. The random samples of the posterior distributions of the growth curve parameters were drawn by using Markov Chain Monte Carlo (MCMC) methods. As a consequence of selection, the selected animals were heavier than the C animals throughout the entire growth curve. Adult body weight, estimated as a parameter of the Gompertz curve, was 7% higher in the selected line. The other parameters of the Gompertz curve were scarcely affected by selection. When selected and control growth curves are represented in a metabolic scale, all differences disappear. PMID:12605849

    2007-03-01

    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.

    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.

    Contemporary sedimentation in the Azov Sea was estimated spatially detailed mathematical model for transport and sedimentation of the particulate matter. The model TRASEAS includes dynamic of suspended and eposited terrigenous matter in water column and at the bottom and accounts for realistic bathymetry. Distinct spatiotemporal features of the terrigenous sedimentation in the second half of the 20th century were recognized. The decrease in the accumulation of terrigenous sediments and diminishing in the areas with a negative balance of the terrigenous matter was found. This was related to the 2.5-fold fall in the volumes of the matter supplied from land. In general, during the second half of the 20thcentury the rate of sedimentation decreased from 1000 to 400 g/m2/year with spatial variation. In the central part of the sea, which is relatively far from source of terrigenous matter, the rate of sedimentation has value of about 300 g/m2/year. In Taganrog Bay and in the inner sea , areas with a negative balance of terrigenous sedimentation increased up to 30%.

    The main function of erythropoietin (EPO) is to maintain red blood cell mass, but in recent years, increasing evidence has suggested a wider biological role not solely related to erythropoiesis, e.g. angiogenesis and tissue protection. EPO is produced in the liver during fetal life, but the main production shifts to the kidney after birth. The liver maintains a production capacity of up to 10% of the total EPO synthesis in healthy controls, but can be up-regulated to 90-100%. However, the hepatic EPO synthesis has been shown not to be adequate for correction of anemia in the absence of renal-derived EPO. Elevated circulating EPO has been reported in a number of diseases, but data from cirrhotic patients are sparse and the level of plasma EPO in patients with cirrhosis is controversial. Cirrhosis is characterized by liver fibrosis, hepatic dysfunction and the release of proinflammatory cytokines, which lead to arterial hypotension, hepatic nephropathy and anemia. An increase in EPO due to renal hypoperfusion, hypoxia and anemia or an EPO-mediated hepato-protective and regenerative mechanism is plausible. However, poor hepatic synthesis capacity, a decreasing co-factor level and inflammatory feedback mechanisms may explain a potential insufficient EPO response in end-stage cirrhosis. Finally, the question remains as to whether a potential increase in EPO production in certain stages of cirrhosis originates from the kidney or liver. This paper aims to review contemporary aspects of EPO relating to chronic liver disease.

    As society ages and the frequency of falls increases, counteracting gait and posture decline is a challenging issue for countries of the developed world. Previous studies have shown that exercise and hazard management help to improve balance and/or decrease the risks for falling in normal aging. Motor activity based on motor-skill learning, particularly dance, can also benefit balance and decreases falls with age. Recent studies have suggested that older dancers have better balance, posture, or gait than non-dancers. Additionally, clinical or laboratory measures have shown improvements in some aspects of balance after dance interventions in elderly trainees. This study examined the impact of contemporary dance (CD) and of fall prevention (FP) programs on postural control of older adults. Posturography of quiet upright stance was performed in 41 participants aged 59-86 years before and after 4.4-month training in either CD or FP once a week. Though classical statistic scores failed to show any effect, dynamic analyses of the center-of-pressure displacements revealed significant changes after training. Specifically, practice of CD enhanced the critical time interval in diffusion analysis, and reduced recurrence and mathematical stability in recurrence quantification analysis, whereas practice of FP induced or tended to induce the reverse patterns. Such effects were obtained only in the eyes open condition. We suggest that CD training based on motor improvisation favored stochastic posture inducing plasticity in motor control, while FP training based on more stereotyped behaviors did not.

  17. Yesterday's ethics in contemporary medicine - is it still of concern?

    PubMed

    2011-01-01

    Discussions on questions and problems of medical ethics are on everyone's lips. The debates center for instance around the just allocation of public resources, demographical changes in our society or the guarantee of patient autonomy, thus posing questions on the technical progress in modern medicine. These contemporary conflicts in medicine are numerous, but not all of them are new; rather, the discussion in medical ethics on these dilemmas is bound to contexts and has historical roots. Some of these conflicts reach back to the medicine of the Renaissance and Antiquity, thus assigning actuality to the historical viewpoint. Taking history into account, one can benefit from a timeless content and not least get a feeling for historicity and contingency. Considering the creation of identity, the old authorities also represent central normative reference points for the ethical competence of physicians understood as an attitude within an interpersonal medicine. For this reason, the heritage of Hippocrates, which encompasses values and norms of the Hippocratic Oath, needs to be respected. Apart from other dimensions of knowledge and skills, the development of an individual ethical competence also requires awareness of the past, leading to an understanding for the historical, social and cultural relativity of medical action.

  18. Heavy viewing: emergent frames in contemporary news coverage of obesity.

    In the last 10 years, rising rates of obesity in the United States have drawn significant and increasing public attention from various quarters, which has led to commensurately increased news coverage of the issue. A handful of scholars to date have examined how obesity has been "framed" in the news, given that news framing of issues has proven effects on cultural and political attitudes, practices, and policies as regards the subject of coverage. Consistent with these studies, this qualitative framing analysis assesses how obesity is framed in more recent mainstream news coverage. Framing patterns identified in this analysis represent a notable departure from those identified in earlier studies, specifically as relevant to troubling the individual/environmental attribution binary that historically has characterized public discourse around obesity, in particular, and health more broadly. These findings signal important shifts for contemporary cultural attitudes toward obesity and, accordingly, public health policies designed to redress the issue. Further, the findings suggest a reconsideration and elaboration of established tenets of framing theory.

    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.

    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.

    2011-01-01

    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

    Historical representations explicitly depicting Blacks as apelike have largely disappeared in the United States, yet a mental association between Blacks and apes remains. Here, the authors demonstrate that U.S. citizens implicitly associate Blacks and apes. In a series of laboratory studies, the authors reveal how this association influences study participants' basic cognitive processes and significantly alters their judgments in criminal justice contexts. Specifically, this Black-ape association alters visual perception and attention, and it increases endorsement of violence against Black suspects. In an archival study of actual criminal cases, the authors show that news articles written about Blacks who are convicted of capital crimes are more likely to contain ape-relevant language than news articles written about White convicts. Moreover, those who are implicitly portrayed as more apelike in these articles are more likely to be executed by the state than those who are not. The authors argue that examining the subtle persistence of specific historical representations such as these may not only enhance contemporary research on dehumanization, stereotyping, and implicit processes but also highlight common forms of discrimination that previously have gone unrecognized.

    The interdisciplinary field of reflections on food as politics goes through a process of expansion and overflow to the private sphere, and routine daily food consumption. This process seems to be a reflection of transformations in the global agrifood markets, the wide publicity and awareness of food hazards and the politicization of consumption. To the extent that individuals are to assume responsibility for the environmental and social consequences of their everyday choices, the specificity of political power in contemporary societies goes beyond the institutional level (food security and nutrition, social inequalities in access to food, agricultural policies and regulations advertising of food) to meet the private sphere. This paper shows, initially, some of the recent debates about the process of politicization of consumption and then explores a theoretical reflection on the ethical, political and ideological habits that relate to food consumption, including the locations and ways of acquiring and food preparation, the values of environmental preservation, solidarity with local producers and reflexive caution against food risks. Finally, points to a research agenda capable of capturing the processes of politicization of food and consumer practices in the field of political power.

    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.

    In contemporary laboratory animal facilities, workplace exposure to zoonotic pathogens, agents transmitted to humans from vertebrate animals or their tissues, is an occupational hazard. The primary (e.g., macaques, pigs, dogs, rabbits, mice, and rats) and secondary species (e.g., sheep, goats, cats, ferrets, and pigeons) of animals commonly used in biomedical research, as classified by the American College of Laboratory Animal Medicine, are established or potential hosts for a large number of zoonotic agents. Diseases included in this review are principally those wherein a risk to biomedical facility personnel has been documented by published reports of human cases in laboratory animal research settings, or under reasonably similar circumstances. Diseases are listed alphabetically, and each section includes information about clinical disease, transmission, occurrence, and prevention in animal reservoir species and humans. Our goal is to provide a resource for veterinarians, health-care professionals, technical staff, and administrators that will assist in the design and on-going evaluation of institutional occupational health and safety programs.

    Our aims were to demonstrate that natural selection is operating on contemporary humans, predict future evolutionary change for specific traits with medical significance, and show that for some traits we can make short-term predictions about our future evolution. To do so, we measured the strength of selection, estimated genetic variation and covariation, and predicted the response to selection for women in the Framingham Heart Study, a project of the National Heart, Lung, and Blood Institute and Boston University that began in 1948. We found that natural selection is acting to cause slow, gradual evolutionary change. The descendants of these women are predicted to be on average slightly shorter and stouter, to have lower total cholesterol levels and systolic blood pressure, to have their first child earlier, and to reach menopause later than they would in the absence of evolution. Selection is tending to lengthen the reproductive period at both ends. To better understand and predict such changes, the design of planned large, long-term, multicohort studies should include input from evolutionary biologists.

    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.

    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

    As society ages and the frequency of falls increases, counteracting gait and posture decline is a challenging issue for countries of the developed world. Previous studies have shown that exercise and hazard management help to improve balance and/or decrease the risks for falling in normal aging. Motor activity based on motor-skill learning, particularly dance, can also benefit balance and decreases falls with age. Recent studies have suggested that older dancers have better balance, posture, or gait than non-dancers. Additionally, clinical or laboratory measures have shown improvements in some aspects of balance after dance interventions in elderly trainees. This study examined the impact of contemporary dance (CD) and of fall prevention (FP) programs on postural control of older adults. Posturography of quiet upright stance was performed in 41 participants aged 59–86 years before and after 4.4-month training in either CD or FP once a week. Though classical statistic scores failed to show any effect, dynamic analyses of the center-of-pressure displacements revealed significant changes after training. Specifically, practice of CD enhanced the critical time interval in diffusion analysis, and reduced recurrence and mathematical stability in recurrence quantification analysis, whereas practice of FP induced or tended to induce the reverse patterns. Such effects were obtained only in the eyes open condition. We suggest that CD training based on motor improvisation favored stochastic posture inducing plasticity in motor control, while FP training based on more stereotyped behaviors did not. PMID:22232582

    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.

    We examine the influence of socio-environmental (and birth cohort specific) effects on both adult height and gender dimorphism (height gap). Our data set is from contemporary Spain, a country governed by an authoritarian regime for about 40 years. Both OLS and quantile regression approaches are used to examine these patterns. Furthermore, we then draw upon a Blinder-Oaxaca decomposition approach to explain the influence of socio-political environment in explaining gender dimorphism. Our findings point to a significant increase in adult height in the generations that benefited from the country's economic liberalization in the 1950s, and especially among those brought up after the transition to democracy in the 1970s. In contrast, individual heterogeneity suggests that only in recent generations has "height increased more among the tallest". We also find that the effects of education on height are greater among shorter individuals. Although the mean gender difference in height is 11.7cm, birth cohort and capabilities effects along with other controls explain on average roughly 4% of the gender height dimorphism, irrespective of the quantile considered.

    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.

    1976-01-01

    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.

    2011-12-01

    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.

    A myriad of previous studies from a variety of disciplines has shown several effects of music on mind and body. This study investigated the relationship between different categories of contemporary music (n = 6) and the mood states of a group of students (n = 12), using the Profile of Mood States (POMS), to measure mood before and after exposure to these different pieces of music. When analysed together, all six pieces of music produced an overall change in mood (P = 0.008) as measured by 2-way repeated measures analysis of variance (ANOVA). When each category was examined individually, four categories of music produced highly significant changes in mood: the tense category (score -4.0 +/- 1.8 POMS Units; P < 0.001); depressed category (+0.5 +/- 0.2; P < 0.001); angry category (+0.9 +/- 1.6; P < 0.03); and the all moods category (1.6 +/- 0.3; P < 0.04). One piece of dance music produced changes in all mood categories, giving the largest positive mean mood change. By contrast, the popular/independent music, associated with the tense category, produced the largest negative mean mood change. The five POMS mood states were analysed separately for each piece of music. These findings are consistent with previous work. In addition, the finding of the effects of specific music categories on mood may have important implications for therapy in mental health and mental health nursing.

    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.

    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.

    The 20th century eugenics movement in the USA and contemporary practices involving prenatal screening (PNS), prenatal diagnosis (PND), abortion and preimplantation genetic diagnosis (PGD) share important morally relevant similarities. 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.

  1. Extrapituitary growth hormone and growth?

    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.

    2009-12-01

    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'.

    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.

    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.

    The clinically relevant pathologic consequences of primary ocular, genital, or respiratory human infection by members of the genus Chlamydia are conjunctivitis, cervicitis, urethritis and sinusitis. The major complications and sometimes debilitating evolutionary outcomes of these infections include: trichiasis and cicatrizing trachoma, endometritis or pelvic inflammatory disease and involuntary tubal factor infertility and bronchopulmonary pneumonia. These diseases, in addition to other chlamydia-associated chronic syndromes (e.g., artherosclerosis, multiple sclerosis and Alzheimer's disease), pose serious public healthcare and huge budgetary concerns. The current medical opinion is that an efficacious prophylactic vaccine is a sine qua non--to control the morbidity of chiamydial infection in the human population. The research goal for an efficacious human chlamydial vaccine has faced key challenges to define the elements of protective immunity to facilitate vaccine evaluation, the judicious selection of appropriate vaccine candidates that possess stable antigenic and immunologic properties and the development of effective delivery vehicles and adjuvants to boost immune effectors to achieve long-term protective immunity. Progress in the functional immunobiology of Chlamydia has established the essential immunologic paradigms for vaccine selection and evaluation, including the obligatory requirement for a vaccine to induce T-helper Type 1 immune response that controls chlamydiae. Recent advances in chlamydial genomics and proteomics should enhance the identification of likely chlamydial gene products that fulfill the antigenic requirements of putative vaccine candidates. Major inroads are however needed in the construction and development of novel and effective delivery systems, such as vectors and adjuvants. This review summarizes the status of contemporary chlamydial vaccine research and promising trends fueling the growing optimism for an efficacious vaccine. The

    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.

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

    NASA Astrophysics Data System (ADS)

    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.

  11. Contemporary issues and future directions for research into pathological gambling.

    PubMed

    The recent healthy increase in research into all aspects of gambling is noted. The dominant theme accounting for most of this research is the mental disorder model of pathological gambling and measures that have been derived from this conceptualization. It is suggested that an alternative approach focusing on the construct of choice or subjective control over gambling may be a research direction that will ensure that progress is maintained. In this paper a context for the discussion is provided by first identifying briefly fundamental conceptual and methodological issues associated with the mental disorder model. In particular it is argued that the heterogeneity of the diagnosis of pathological gambling makes the research task of assessing truly independent variables extremely difficult. Subsequently an illustrative schema is presented that demonstrates both the potential advantages and some of the complexities associated with the dependent variable of self-control over gambling behaviour. The main advantages are argued to be (a) the focus of research is narrowed to one potential cause of harmful impacts rather than the great diversity of impacts themselves, (b) prospective studies of regular gamblers in real gambling venues may be a key source of insight into the development of pathological gambling and (c) it promotes the development of theoretical links with the mainstream of the discipline of psychology. Despite the conceptual difficulties that may be associated with the variable of self-control, it is suggested that these may be overcome because contemporary research into the addictive behaviours has demonstrated considerable success in the definition and measurement of control and related themes such as craving, restraint and temptation.

    Degenerative spondylolisthesis is a common presentation, yet the best surgical treatment continues to be a matter of debate. Interbody fusion is one of a number of options, but its exact role remains ill defined. The aim of this study was to provide a contemporary review of the literature to help determine the role, if any, of interbody fusion in the surgical treatment of degenerative spondylolisthesis. A systematic review of the literature since 2005 was performed. Details on study size, patient age, surgical treatments, levels of slip, patient reported outcome measures, radiographic outcomes, complications and selected utility measures were recorded. Studies that compared a cohort treated with interbody fusion and at least one other surgical intervention for comparison were included for review. Only studies examining the effect in degenerative spondylolisthesis were included. Two authors independently reviewed the manuscripts and extracted key data. Thirteen studies were included in the final analysis. A total of 565 underwent interbody fusion and 761 underwent other procedures including decompression alone, interspinous stabilisation and posterolateral fusion with or without instrumentation. Most studies were graded Level III evidence. Heterogeneous reporting of outcomes prevented formal statistical analysis. However, in general, studies reviewed concluded no significant clinical or radiographic difference in outcome between interbody fusion and other treatments. Two small studies suggested interbody fusion is a better option in cases of definite instability. Interbody fusion only provided outcomes as good as instrumented posterolateral fusion. However, most studies were Level III, and hence, we remain limited in defining the exact role of interbody fusion-cases with clear instability appear to be most appropriate. Future work should use agreed-upon common outcome measures and definitions.

    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.

    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.

    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.

    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

    Strong selection in the Israeli Holstein dairy cattle population over the last three decades should have left clear signatures of selection. Two experimental approaches were applied to detect evidence of contemporary selection based on the 54K BeadChip genotypes of ~1000 Israeli Holstein bulls: (i) the long-range haplotype test, which searches for structural evidence resulting from selective sweep, and (ii) direct analysis of the changes in haplotypes frequencies over time combined with linkage disequilibrium blocks haplotype-based association analysis. Ten traits were analyzed: the PD07 Israeli selection index, milk, milk fat, % fat, milk protein, % protein, somatic cell score, female fertility, milk production persistency and herd life. The long-range haplotype test detected ~15% of the 3288 haplotypes that showed significant positive frequency trends (P < 0.05) and was significantly correlated with the substitution effects of the haplotypes and the selection intensities for the different traits. Thirty signatures of recent selection, which correspond to both approaches and affect the Israeli PD07 selection index, were identified on 17 of the 29 autosomes. The second experimental approach also was used to estimate the selection intensity of the different traits. The correlation between the selection intensities for the traits analyzed, derived from changes in haplotype frequencies in the population of bulls, and those derived from trait-based analysis of the cow population was 0.93 over all traits. Thus, the changes in haplotypes frequencies in the bulls' population accurately estimate genetic trends in the general cow population and can be used to detect signatures of recent selection.

    Introduction Hemorrhagic cystitis presents a difficult clinical challenge, yet data regarding treatment options is sparse. Here, we sought to evaluate outcomes of a contemporary cohort of patients treated with intravesical formalin for hemorrhagic cystitis. Methods We identified a retrospective cohort of eight patients managed with formalin for hemorrhagic cystitis from 2000–2014. All patients failed prior measures, including bladder irrigation, clot evacuation, and other intravesical agents. Treatment success was defined as hematuria resolution during the given hospitalization without use of additional invasive therapies. We also evaluated treatment complications and additional treatments following hospital dismissal. Results Etiology of cystitis was radiation for malignancy in all cases. The formalin concentration ranged from 1–4%, with escalation used in treatment failures. Five patients (62.5%) received a single dose of 1% formalin, two patients received two doses, and one patient received three doses. Notably, intraoperative cystography identified vesicoureteral reflux (VUR) in 50.0% of patients. Six patients (75.0%) achieved treatment success, with a median time to resolution of four days (range 1–17 days). Of those refractory to formalin, one was managed with indwelling nephrostomy tubes and one underwent cystectomy. Median followup was eight months. Of the responders, two eventually required cystectomy, one for recurrent hematuria and one for recalcitrant bladder neck contracture and bladder dysfunction. The remaining four patients (50%) required no additional therapy. Conclusions Formalin remains an important tool for treating refractory hemorrhagic cystitis, with roughly 75.0% of patients requiring no additional therapy prior to hospital discharge. Notably, there is a risk of bladder dysfunction following formalin. PMID:28360951

    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.

  3. The Coevolution of Galaxies and Supermassive Black Holes: Insights from Surveys of the Contemporary Universe

    2014-08-01

    We summarize what large surveys of the contemporary Universe have taught us about the physics and phenomenology of the processes that link the formation and evolution of galaxies with their central supermassive black holes. We present a picture in which the population of active galactic nuclei (AGNs) can be divided into two distinct populations. The radiative-mode AGNs are associated with black holes (BHs) that produce radiant energy powered by accretion at rates in excess of ˜1% of the Eddington limit. They are primarily associated with less massive BHs growing in high-density pseudobulges at a rate sufficient to produce the total mass budget in these BHs in ˜10 Gyr. The circumnuclear environment contains high-density cold gas and associated star formation. Major mergers are not the primary mechanism for transporting this gas inward; secular processes appear dominant. Stellar feedback is generic in these objects, and strong AGN feedback is seen only in the most powerful AGNs. In jet-mode AGNs the bulk of energetic output takes the form of collimated outflows (jets). These AGNs are associated with the more massive BHs in more massive (classical) bulges and elliptical galaxies. Neither the accretion onto these BHs nor star formation in their host bulge is significant today. These AGNs are probably fueled by the accretion of slowly cooling hot gas that is limited by the feedback/heating provided by AGN radio sources. Surveys of the high-redshift Universe paint a similar picture. Noting that the volume-averaged ratio of star formation to BH growth has remained broadly constant over the past 10 Gyrs, we argue that the processes that linked the cosmic evolution of galaxies and BHs are still at play today.

    We present the latest updating and the complete collection of data on the contemporary stress orientations in Italy. Data are relative to different stress indicators: borehole breakouts from deep drillings, crustal earthquake focal mechanisms and fault data. With respect to the previous compilation, performed in 2004, 206 new entries complete the definition of the horizontal stress orientation and tectonic regime in the most part of the territory, and bring new information mainly in Sicily and along the Apenninic belt. With an increase of 37% with respect to the previous compilation, now the global Italian dataset consists of 499 records with a reliable quality for stress maps. The total dataset includes the following active stress indicators: 56% borehole breakouts, 39% single earthquake focal mechanisms, and 5% represented by formal inversions of focal mechanisms, faults and overcoring data. A quality ranking between A and E is assigned to each stress data, with A being the highest quality and E the lowest. Only A-, B- and C-quality stress indicators are considered consistent for analyzing stress patterns. Depth interval of the entire dataset is between 0 to 40 km. The results in map are reported in terms of minimum horizontal stress (Shmin) because most of earthquakes present an extensional regime. Concerning breakouts, their orientations correspond to Shmin; since all the considered faults are normal faults, we assume the Shmin direction as perpendicular to the fault strike when no information on slip direction is available. The achieved results can be summarized in 3 main points: i) in some areas of Italy (Sicily, Friuli and Po Plain in the northern Italy), the alignment of horizontal stresses closely matches the ~N-S direction of ongoing crustal motions with respect to stable European plate. This result can be associated to the first-order stress field that drives the plate movement; ii) along the entire Apenninic belt - from north to south- a diffuse

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.

    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.

  15. Growth Kinetics in Epitaxial Growth

    NASA Astrophysics Data System (ADS)

    Hessinger, Uwe

    Growth kinetics in heteroepitaxial growth are related to the nucleation and growth of atomic-height islands during the deposition of a material on a dissimilar substrate. Experimental measurements of the initial morphology of CaF_2 films deposited on Si(111) substrates were performed. These measurements consisted of photoemission spectroscopy and diffraction, which give sub-nanometer scale information averaged over the entire sample, and plan-view transmission electron microscopy, which gives localized information on a scale of several nanometers. These results, combined with others in the literature, revealed four distinct growth morphologies dependent on the deposition rate, substrate temperature and spacing between atomic-height steps on the surface, two of which had not been previously explained. A model based on two extant theories of homoepitaxial growth kinetics was developed to explain the different observed growth morphologies for the heteroepitaxial system CaF_2/Si(111). The first theory deals with whether the initial nucleation will occur at substrate steps or through adatom collisions on flat terraces, while the second deals with the nucleation of subsequent layers as these initial atomic islands increase in size. In extending these theories to heteroepitaxy, very different rates of upper-layer nucleation for the different size islands that nucleated at steps and on terraces are predicted. By applying this theory to CaF_2/Si(111), the diffusion barriers for CaF_2 molecule migration both on the reacted Si-Ca-F interface layer and on subsequent CaF_2 layers was extracted. The four different growth morphologies are explained within a common framework. The theory is quite general, and should apply to most heteroepitaxial systems. These theories were extended to predict a means by which the upper-layer nucleation may be inhibited while the underlying layer is completed. This method involves initiating the growth at conditions favoring many, small islands on

    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.

    The rapid rise in antimicrobial resistance in bacteria has generated an increased demand for the development of novel therapies to treat contemporary infections, especially those caused by methicillin-resistant Staphylococcus aureus (MRSA). However, antimicrobial development has been largely abandoned by the pharmaceutical industry. We recently isolated the previously described thiopeptide antibiotic nosiheptide from a marine actinomycete strain and evaluated its activity against contemporary clinically relevant bacterial pathogens. Nosiheptide exhibited extremely potent activity against all contemporary MRSA strains tested including multiple drug-resistant clinical isolates, with MIC values 0.25 mg l(-1). Nosiheptide was also highly active against Enterococcus spp. and the contemporary hypervirulent BI/NAP1/027 strain of Clostridium difficile but was inactive against most Gram-negative strains tested. Time-kill analysis revealed nosiheptide to be rapidly bactericidal against MRSA in a concentration- and time-dependent manner, with a nearly 2-log kill noted at 6 h at 10 × MIC. Furthermore, nosiheptide was found to be non-cytotoxic against mammalian cells at >100 × MIC, and its anti-MRSA activity was not inhibited by 20% human serum. Notably, nosiheptide exhibited a significantly prolonged post-antibiotic effect against both healthcare- and community-associated MRSA compared with vancomycin. Nosiheptide also demonstrated in vivo activity in a murine model of MRSA infection, and therefore represents a promising antibiotic for the treatment of serious infections caused by contemporary strains of MRSA.

  18. Landscape genetics in a changing world: disentangling historical and contemporary influences and inferring change.

    Epps, Clinton W; Keyghobadi, Nusha

    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.

    Video analysis has become a useful tool in the preparation for sport performance and its use has highlighted the different physiological demands of seemingly similar sports and playing positions. The aim of the current study was to examine the performance differences between classical ballet and contemporary dance. In total 93 dance performances (48 ballet and 45 contemporary) were analysed for exercise intensity, changes in direction and specific discrete skills (e. g., jumps, lifts). Results revealed significant differences between the 2 dance forms for exercise intensity (p<0.001), changes in direction (p<0.001) and discrete skills (p<0.05) with gender differences noted in the latter (p<0.05). Ballet was characterised by longer periods at rest (38 s x min(-1)) and high to very high exercise intensities (9 s x min(-1)), whilst contemporary dance featured more continuous moderate exercise intensities (27 s x min(-1)). These differences have implications on the energy systems utilised during performance with ballet potentially stressing the anaerobic system more than contemporary dance. The observed high rates in the discrete skills in ballet (5 jumps x min(-1); 2 lifts x min(-1)) can cause local muscular damage, particularly in relatively weaker individuals. In conclusion, classical ballet and contemporary dance performances are as significantly different in the underlying physical demands placed on their performers as the artistic aspects of the choreography.

  20. 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.

    This paper summarizes the current state of knowledge with respect to post-Paleozoic tectonic features and their relationship to the contemporary stress field outside coastal plain regions of the eastern United States. Until the early 1970s very little was known about such features. By the end of 1992 post-Paleozoic faults had been observed in at least five widely separated regions. Pleistocene-Holocene surface ruptures and liquefaction features had been observed over a steadily increasing area of the upper Mississippi embayment and adjacent regions. Ages of most recent ruptures on post-Paleozoic faults range from uncertain to Holocene and their senses of motion are compatible with the contemporary stress field. The cumulative amount of post-Paleozoic displacement on these faults is generally less than three meters. Fracture systems in Paleozoic rocks also are compatible with the contemporary stress field over a wide region of Indiana.

    Etiologic diagnostics of sepsis is one of the most difficult problems of contemporary medicine due to a wide variety of sepsis causative agents, many of which are components of normal human microflora. Disadvantages of contemporary "golden standard" of microbiologic diagnostics of sepsis etiology by seeding of blood for sterility are duration of cultivation, limitation in detection of non-cultivable forms of microorganisms, significant effect of preliminary empiric antibiotics therapy on results of the analysis. Methods of molecular diagnostics that are being actively developed and integrated during the last decade are deprived of these disadvantages. Main contemporary methods of molecular-biological diagnostics are examined in the review, actualdata on their diagnostic characteristic are provided. Special attention is given to methods of PCR-diagnostics, including novel Russian developments. Methods of nucleic acid hybridization and proteomic analysis are examined in comparative aspect. Evaluation of application and perspectives of development of methods of molecular diagnostics of sepsis is given.

    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 1,930teragrams of carbon a year (TgCyr-1), followed by a prolonged decrease averaging 190TgCyr-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.

    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.

    Trauma resulting in hemorrhage from vascular disruption within the torso is a challenging scenario, with a propensity to be lethal in the first hour following trauma. The term noncompressible torso hemorrhage (NCTH) was only recently coined as part of contemporary studies describing the epidemiology of wounding during the wars in Afghanistan and Iraq. This article provides a contemporary review of NCTH, including a unifying definition to promote future study as well as a description of resuscitative and operative management strategies to be used in this setting, and sets a course for research to improve mortality following this vexing injury pattern.

    This article studies a contemporary treatment approach toward both diabetes and depression management by vanadium-enriched Cordyceps sinensis (VECS). Streptozotocin-induced hyperglycemic rats were used in the study. After the rats were administered with VECS, a significant reduction in blood glucose levels was seen (P < .05) and the levels of serum insulin increased significantly (P < .05). At the same time, the study revealed a significant decrease in immobility with a corresponding increase in the swimming and climbing behavior in hyperglycemic rats following VECS treatment. The results described herein demonstrate that VECS is a contemporary treatment approach that advocates an aggressive stance toward both diabetes and depression management. PMID:21799679

    Dairy products are associated with numerous health benefits. They are good source of nutrients like carbohydrates, protein (bioactive peptides), lipids, minerals and vitamins which are essential for growth, development and maintenance of the human body. Accordingly, dairy bioactive peptides are one of targeted compounds present in different dairy products. Dairy bioactive compounds can be classified as anti-hypertensive, anti-oxidative, immmunomodulant, anti-mutagenic, anti-microbial, opoid, anti-thrombotic, anti-obesity and mineral-binding agents depending upon biological functions. These bioactive peptides can easily be produced by enzymatic hydrolysis, during fermentation and gastrointestinal digestion. For the reason, fermented dairy products like yogurt, cheese and sour milk are gaining popularity worldwide and considered excellent sources of dairy peptides. Furthermore, fermented and non-fermented dairy products are associated with lower risks of hypertension, coagulopathy, stroke and cancer insurgences. The current review article is an attempt to disseminate general information about dairy peptides and their health claims to scientists, allied stakeholders and certainly readers.

  9. 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.

  10. 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.

    2014-01-01

    Anthracimycin is a recently discovered novel marine-derived compound with activity against Bacillus anthracis. We tested anthracimycin against an expanded panel of Staphylococcus aureus strains in vitro and in vivo. All strains of S. aureus tested, including methicillin-sensitive (MSSA), methicillin-resistant (MRSA), and vancomycin-resistant strains of S. aureus were sensitive to anthracimycin at minimum inhibitory concentrations (MIC) of < 0.25 mg/L. Although its post-antibiotic effects were minimal, anthracimycin exhibited potent and rapid bactericidal activity, with a > 4-log kill of USA300 MRSA within 3 hours at 5 times its MIC. At concentrations significantly below the MIC, anthracimycin slowed MRSA growth and potentiated the bactericidal activity of the human cathelicidin, LL-37. The bactericidal activity of anthracimycin was somewhat mitigated in the presence of 20% human serum, and the compound was minimally toxic to human cells, with an IC50 = 70 mg/L against human carcinoma cells. At concentrations near the MIC anthracimycin inhibited S. aureus nucleic acid synthesis as determined by optimized macromolecular synthesis methodology, with inhibition of DNA and RNA synthesis occurring in the absence of DNA intercalation. Anthracimycin at a single dose of 1 or 10 mg/kg was able to protect mice from MRSA-induced mortality in a murine peritonitis model of infection. Anthracimycin provides an interesting new scaffold for future development of a novel MRSA antibiotic. PMID:24736856

  13. Population growth.

    PubMed

    1984-01-01

    Despite efforts to reduce population growth, the World Bank projects a world population of 10 billion by 2050, with 7 billion living in developing countries. From October 1979 to September 1984, the US Agency for International Development (AID) funded the Research Triangle Institute's (RTI) Integrated Population and Development Planning (IPDP) project to assess rapid population growth effects in 25 developing countries. In October 1984, US AID extended funding for the program, nicknamed INPLAN, for 3 years, at a cost of $6.3 million. Up to 50% of people in developing countries are under age 15, a fact that guarantees large population increases for the next 50-75 years. Also, many regions have been slow to correlate high fertility with socioeconomic development, and in some areas, fertility is actually increasing. INPLAN aims to make governments more aware of population dynamics and to provide training and tools for effective development planning. 40% of INPLAN's work will be done in Africa, 25% in Latin America, and 20% in Asia, with some activity in the Near East. One project in Egypt, involving the use of model generation by microcomputer, was developed by RTI to show rural to urban migration and rapid population growth affects on the educational system. INPLAN expects to develop several other planning sector models on labor force and employment, health and family planning, food supply, housing, and urban development, and apply them to 20-25 countries. Another project provided 9 microcomputer systems and training to Nigerian government agencies. IMPLAN will purchase and distribute 60 such systems in the future.

  17. How a network of conservationists and population control activists created the contemporary US anti-immigration movement.

    PubMed

    Normandin, Sebastian; Valles, Sean A

    2015-06-01

    Continuing historical narratives of the early twentieth century nexus of conservationism, eugenics, and nativism (exemplified by Madison Grant), this paper traces the history of the contemporary US anti-immigration movement's roots in environmentalism and global population control activism, through an exploration of the thoughts and activities of the activist, John Tanton, who has been called "the most influential unknown man in America." We explore the "neo-Malthusian" ideas that sparked a seminal moment for population control advocacy in the late 1960s and early 1970s, leading to the creation of Zero Population Growth (ZPG). After rising to the presidency of ZPG, Tanton, and ZPG spun off the Federation for American Immigration Reform. After leaving ZPG's leadership, Tanton created additional anti-immigration advocacy groups and built up connections with existing organizations such as the Pioneer Fund. We trace Tanton's increasingly radical conservative network of anti-immigration advocates, conservationists, and population control activists to the present day. Tanton's archived papers illustrate, among other things, his interactions with collaborators such as ecologist Garrett Hardin (author of the famous "Tragedy of the Commons") and his documented interest in reviving eugenics. We contend that this history of Tanton's network provides key insights into understanding how there came to be an overlap between the ideologies and activist communities of immigration restrictionism, population control, conservationism and eugenics.

    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.

  10. 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.
