    High-reliability components for high-consequence systems require detailed testing of operation after having undergone highly accelerated stress testing (HAST) under unusual conditions of high-temperature and humidity. This paper describes the design and operation of a system called "Wormwood" that is a highly multiplexed temperature measurement system that is designed to operate under HAST conditions to allow measurement of the temperature as a function of time and position in a HAST chamber. HAST chambers have single-point temperature measurements that can be traceable to NIST standards. The objective of these "Wormwood" measurements is to verify the uniformity and stability of the remaining volume of the HAST chamber with respect to the single traceable standard.

    It is with great sadness that we learned that our friend and former colleague, David Warner, passed away on Christmas Eve. The funeral was held the following Monday. David was a "linac man". His career centred around linacs, but with a multitude of different subjects. He began at CERN by building the 3 MeV linac in the extension of the South Hall. He did pioneering work on this machine, which paved the way towards the design of the Alvarez cavities for the CERN Linac 2, for which he was responsible. After this challenge was successfully finished, David was the first member of the small but growing team, that was in charge of building the LEP Injector Linacs (LIL). After having been recognised as a proton linac expert, he quickly converted to electron linacs where he soon became the respected key expert for the design, parameters and ultimate performance of LIL. His predilection for precise and detailed documentation, and his vision that the know-how acquired with LIL should be preserved a...

    In April 1852 in Cape Town, South Africa, Dr David Livingstone, then 39 years of age and yet to commence the explorations of Africa which would bring him to public attention, underwent the surgical procedure of uvulectomy. This article reviews the history of Livingstone's uvulectomy and its indications and outcome, as documented by his own writings. The practice of uvulectomy in indigenous African societies and some contemporary ideas about uvulectomy are also considered in order to try to ascertain why Livingstone elected to undergo this procedure.

    2001-01-01

    Our purpose was to evaluate and compare the performance of ultra-fast single-shot T2-weighted sequences: echo-planar imaging (EPI) versus half-Fourier single-shot turbo spin-echo (HASTE) and to assess the usefulness of their combined reading. Comparative experiments on a phantom as well as a prospective clinical study in 47 patients were done. Axial images acquired with the following methods were compared: (a) HASTE; (b) segmented HASTE (s-HASTE); (c) single-shot spin-echo EPI (SE-EPI); and (d) gradient-echo EPI (GRE-EPI). Quantitative and qualitative criteria as well as lesion detectability were analyzed against the ''gold standard'' fast spin-echo (FSE) sequence. For contrast and contrast-to-noise ratio (CNR) between gray and white matter, GRE-EPI was best. The visibility of small markedly hyperintense lesion was best with HASTE and s-HASTE in the clinical study. Small hyperintense lesions were detected equally well with all four sequences, although all performed significantly worse than FSE. The two HASTE variants were better than the EPIs for the extraaxial lesions. The combination of the GRE-EPI and s-HASTE was judged best, and sometimes superior to the FSE image. HASTE or EPI alone cannot substitute for FSE in the screening evaluation of the brain. However, together, EPI and HASTE could provide comparable diagnostic information to that of FSE because their combination compensates for their individual limitations. (orig.)

    2013-06-01

    In the mid-1950s, a new staff member appeared at the Theory Division of the Physical Institute of the Academy of Sciences (FIAN): David Abramovich Kirzhnits. A Moscow State University alumnus, after graduation he had been assigned to a large defense plant in the city of Gorky, where he had worked for several years as an engineer. He was "liberated" from there by Igor Evgenyevich Tamm, our department head, who managed to transfer him to FIAN. Igor Evgenyevich knew D. A. Kirzhnits - they had met in Moscow before Kirzhnits finished university. At that time Kirzhnits was performing thesis work with professor A. S. Kompaneyets as academic adviser. At his adviser's suggestion, D. Kirzhnits consulted with I. E. Tamm on questions pertaining to the thesis topic. I. E. Tamm took a great liking for the diploma student, and he even wanted to recruit D. A. Kirzhnits for the Theory Division immediately after graduation. But at that time (1949) this proved impossible for several reasons. First, D. Kirzhnits was, as they say, an "invalid of the fifth group" - a Jew - which during those years of violent struggle against cosmopolitanismb often proved an obstacle in looking for work. Second, during the years of mass repressions D. Kirzhnits' father had been arrested on treason charges (according to the charges, he had wanted to sell the Far East to Japan). After intensive investigation his father was released, but he lived only a little longer. Reports of this also could have impeded his acceptance. Third, Igor Evgenyevich didn't have enough weight in officials' eyes at that time and so was unable to overcome "first" and "second."...

    To asses the usefulness of the projectional HASTE sequence in the diagnosis of chronic flank pain caused by obstructive uropathy in comparison with conventional urography. 28 patients with chronic flank pain and hydronephrosis on ultrasound underwent conventional urography and HASTE sequence of static MR urography. The methods were evaluated for image quality, presence, agree, level and cause of urinary tract dilatation. The image quality of the urinary tract on HASTE was good in 57.1% and satisfactory in 42.9%; in conventional urography - good in 28.6%, satisfactory in 42.8% and poor in 28.6%. HASTE demonstrated hydronephrosis and degree of hydronephrosis in all the cases and conventional urography in 25 (83.3%). HASTE identified correctly the site of obstruction in 29 cases (96.7%), and conventional urography in 21 cases (70%). The sensitivity of HASTE in diagnosis of the intrinsic and extrinsic causes of obstruction was 73.7% and 80%, accuracy 73.3% and that of conventional urography 68.4%, 40% and 56.7%, respectively. HASTE is a valuable method in the diagnostics of chronic obstructive uropathy. It allows to evaluate the degree of hydronephrosis, the level and in many cases the cause of obstruction. When the urinary tract is not visualized in conventional urography, static MR urography is especially useful. (author)

  5. A general construction for parallelizing Metropolis−Hastings algorithms

    Calderhead, Ben

    2014-01-01

    Markov chain Monte Carlo methods (MCMC) are essential tools for solving many modern-day statistical and computational problems; however, a major limitation is the inherently sequential nature of these algorithms. In this paper, we propose a natural generalization of the Metropolis−Hastings algorithm that allows for parallelizing a single chain using existing MCMC methods. We do so by proposing multiple points in parallel, then constructing and sampling from a finite-state Markov chain on the proposed points such that the overall procedure has the correct target density as its stationary distribution. Our approach is generally applicable and straightforward to implement. We demonstrate how this construction may be used to greatly increase the computational speed and statistical efficiency of a variety of existing MCMC methods, including Metropolis-Adjusted Langevin Algorithms and Adaptive MCMC. Furthermore, we show how it allows for a principled way of using every integration step within Hamiltonian Monte Carlo methods; our approach increases robustness to the choice of algorithmic parameters and results in increased accuracy of Monte Carlo estimates with little extra computational cost.

    Full Text Available RESUMO Uma das formas de melhoria da qualidade e da produção do tomateiro é a adoção de técnicas adequadas de manejo da cultura, destacando-se o uso da enxertia e o método de condução das plantas. Contudo, no Brasil, há falta de informações que estimulem essas práticas. Por isso, este trabalho teve por objetivo avaliar o desempenho de porta-enxertos para tomateiro, com vigoroso sistema radicular, conduzido com quatro hastes, em fibra da casca de coco, em ambiente protegido. Adotou-se o espaçamento de 2,0 m entrelinhas e 0,40 m entre plantas. Para isso, foi utilizado o delineamento em blocos casualizados, com quatro tratamentos e seis repetições, sendo, os tratamentos, dois porta-enxertos (‘Maxifort’ e ‘Multifort’, autoenxertia (‘Alambra’ em ‘Alambra’, e o pé franco (‘Alambra’. Cada parcela foi constituída de 20 plantas, sendo avaliadas as 14 plantas centrais. Não houve efeito significativo no uso dos porta-enxertos sobre as características de produção e de qualidade dos frutos. Na avaliação do estado nutricional, houve diferenças para os teores de P, Mg e Ca em plantas enxertadas. Portanto, os porta-enxertos ‘Maxifort’ e ‘Multifort’, cultivados nas condições em que o experimento foi realizado, não proporcionaram aumento da produção e da qualidade dos frutos.

    2014-11-01

    We describe the synthesis of a [2]catenane that consists of two triply entwined 114-membered rings, a molecular link. The woven scaffold is a hexameric circular helicate generated by the assembly of six tris(bipyridine) ligands with six iron(II) cations, with the size of the helicate promoted by the use of sulfate counterions. The structure of the ligand extension directs subsequent covalent capture of the catenane by ring-closing olefin metathesis. Confirmation of the Star of David topology (two rings, six crossings) is provided by NMR spectroscopy, mass spectrometry and X-ray crystallography. Extraction of the iron(II) ions with tetrasodium ethylenediaminetetraacetate affords the wholly organic molecular link. The self-assembly of interwoven circular frameworks of controlled size, and their subsequent closure by multiple directed covalent bond-forming reactions, provides a powerful strategy for the synthesis of molecular topologies of ever-increasing complexity.

    Within the fields of medicine and sociology, the descriptor "profession" (along with its brethren: profession, professionalization, and professionalism) has had a rich etymological history, with terms taking on different meanings at different times-sometimes trespassing into shibboleth and jargon. This etymological journey has co-evolved with the career of David Mechanic to whom this issue of the Journal of Health Politics, Policy and Law is devoted. We exploit a provocative metaphor applied to Mechanic's work on the challenges facing medicine as a profession as a playful exegesis on what we call "profession" to excavate an ensconced and encrusted domain of health jargon operating at the tensive interface of society and modern medical work.

  15. Do Surrealismo em David Lynch

    2009-01-01

    Full Text Available O surrealismo, como a arte do seu tempo, propõe uma nova estética, capaz de extrair o belo do absurdo e de instaurar o desvio para que daí surja, de fato, o real. Através da análise de algumas obras de David Lynch e dos livros Les champs magnétiques de Breton e Philippe Soupault e Poisson soluble, de Breton, irei mostrar a pertinência da designação surrealista para a obra do cineasta norte-americano. Lynch, como os surrealistas, constrói uma operação dialética entre o racional/irracional. Ao mesmo tempo em que opera no campo artístico em direção à irracionalidade absoluta, Lynch não nega a sua inserção na sociedade. Acredito que o realizador, como os surrealistas, tenha conseguido encontrar um equilíbrio entre as duas formas de se estar no mundo, racional/irracional, jogando com suas antíteses. O prazer do jogo surrealista consiste em ir até as profundezas do inconsciente e retornar com matéria suficiente para fazer uma obra de arte.Surrealism, as the art of its time, proposes a new aesthetics, one that is able to extract the beautiful from the absurd and to establish the swerve from the standard, from which, in fact, the real comes through. Through the analysis of some works by David Lynch, of Breton and Soupault's Les champs magnétiques, and of Breton's Poisson soluble, I will attempt to show the relevance of the surrealist designation for the work of the American filmmaker. Lynch, like the surrealists, builds a dialectic operation between the rational and the irrational. While operating in the artistic field towards absolute irrationality, Lynch does not deny its role in society. It is my belief that the director, as the surrealists, has managed to find a balance between the two ways of being in the world: rational and irrational; by playing with their antitheses. The pleasure of the surrealist game is to go to the depths of the unconscious and return with sufficient material to make a work of art out of it.

    2018-01-01

    As a single-shot sequence with a long train of refocusing pulses, Half-Fourier Acquisition Single-Shot Turbo-Spin-Echo (HASTE) suffers from high power deposition limiting use at high resolutions and high field strengths, particularly if combined with acceleration techniques such as simultaneous multi-slice (SMS) imaging. Using a combination of multiband (MB)-excitation and PINS-refocusing pulses will effectively accelerate the acquisition time while staying within the SAR limitations. In particular, uncooperative and young patients will profit from the speed of the MB-PINS HASTE sequence, as clinical diagnosis can be possible without sedation. Materials and MethodsMB-excitation and PINS-refocusing pulses were incorporated into a HASTE-sequence with blipped CAIPIRINHA and TRAPS including an internal FLASH reference scan for online reconstruction. Whole brain MB-PINS HASTE data were acquired on a Siemens 3T-Prisma system from 10 individuals and compared to a clinical HASTE protocol. ResultsThe proposed MB-PINS HASTE protocol accelerates the acquisition by about a factor 2 compared to the clinical HASTE. The diagnostic image quality proved to be comparable for both sequences for the evaluation of the overall aspect of the brain, the detection of white matter changes and areas of tissue loss, and for the evaluation of the CSF spaces although artifacts were more frequently encountered with MB-PINS HASTE. ConclusionsMB-PINS HASTE enables acquisition of slice accelerated highly T2-weighted images and provides good diagnostic image quality while reducing acquisition time. Copyright © 2017 Elsevier B.V.

    Forty-six patients with acute displaced subcapital fractures of the femur were treated between December 1982 and December 1984 with Charnley-Hastings bipolar prostheses. The interprosthetic movement in 23 patients was assessed radiologically at least 1 year after surgery. Four patients (17.4 per cent) had no interprosthetic movement in abduction but the remainder (82.6 per cent) had some movement, although only 3 patients (13 per cent) had more than 5 degrees of abduction within the prosthesis.

  3. Obituary: David Stanley Evans, 1916-2004

    Science.gov (United States)

    Bash, Frank N.

    2005-12-01

    David Stanley Evans died on 14 November 2004 in Austin, Texas. He was a noted observational astronomer whose career was divided between South Africa and Texas. He also used the extensive historical collections at the University of Texas to write several books on the history of astronomy. He was born in Cardiff, Wales on 28 January 1916. David received his BA degree in mathematics in 1937 from Kings College, Cambridge. He became a PhD student at Cambridge Observatory in 1937, and was one of Sir Arthur Eddington's last surviving students. He received his PhD degree in 1941 with a dissertation entitled, "The Formation of the Balmer Series of Hydrogen in Stellar Atmospheres." He was a conscientious objector to war and, thus, spent the war years at Oxford working with physicist Kurt Mendelssohn on medical problems, involving cadavers, relating to the war. During these years, David was scientific editor of "Discovery", and he was editor of "The Observatory". David left England in 1946 in order to take up the position of Second Assistant at the Radcliffe Observatory, Pretoria, South Africa. He and H. Knox Shaw were the entire staff after R. O. Redman left, and they aluminized and installed the mirrors in the 74-inch telescope. His notable scientific contribution was to use lunar occultations to measure stellar angular diameters during the 1950s. He succeeded in determining the angular diameter of Antares and determined that Arcturus was not circular but had an elliptical shape. The elliptical shape was later shown to be an instrumental artifact, but the utility of using lunar occultations to measure stellar diameters and stellar multiplicity was conclusively demonstrated. T. Gold presented David's paper on lunar occultation angular diameters at the January 1953 meeting of the Royal Astronomical Society. For the rest of his life, David resented Gold's remarks, because he felt that he had been ridiculed. By 1953, David Evans was Chief Assistant at the Royal Observatory

  4. Excretory MR urography using breathhold three-dimensional FISP: comparison with MR urography using HASTE technique

    To compare the usefulness of gadolinium-enhanced excretory MR urography using breath-hold three-dimensional fast imaging with steady state precession (3-D FISP) with conventional MR urography using the half-Fourier acquisition single-shot turbo spin-echo (HASTE) sequence in the evaluation of obstructive uropathy. Twenty-three patients in whom ultrasonography (US) and/or intravenous urography (IVU) revealed signs of urinary obstruction were enrolled in this study. Fifteen were men and eight were women, and their mean age was 54 (range, 21-80) years. All MR images were obtained using a 1.5T MR unit. MR urography using the HASTE technique (MRU) and gadolinium-enhanced excretory MR urography using the 3D-FISP technique were performed, and in all cases, reconstructions involved maximum intensity projection. For contrast-enhanced MR urography(CEMRU), images were obtained 3, 5, 20, and 30 minutes after the administration of intravenous contrast media, and for selected cases, additional images were obtained until 24 hours after contrast media injection. For qualitative analysis, two experienced radiologists compared CEMRU and MRU in terms of their diagnostic value as regards the level and cause of urinary obstruction, and morphologic accuracy. In addition, signal to noise ration(SNR) and contrast to noise ration (CNR) of the urinary tract at each anatomic level were quantitatively analysed. Quantitative analysis showed that in terms of SNR and CNR of the urinary tract at the level of the mid and distal ureter, CEMRU using 3-D FISP was better than MRU using HASTE (p less than 0.05). Qualitative analysis indicated that for the depiction of the whole length of normal ureter, and detection of the level of obstruction, anatomic anomalies and intrinsic tumors, 3-D FISP was superior to HASTE. There was, however, no difference between these two modalities in the diagnosis of ureteral stone and the degree of hydronephrosis. In addition, 3-D FISP was better than HASTE for the

  8. MR cholangiopancreatography of pancreaticobiliary diseases: Comparison of single-shot RARE and multislice HASTE sequences

    Energy Technology Data Exchange (ETDEWEB)

    Morrin, Martina M.; Farrell, Richard J.; McEntee, Gerry; MacMathuna, Padraic; Stack, John P.; Murrah, John G

    2000-11-01

    AIMS: We prospectively compared two breath-hold magnetic resonance cholangiopancreatography (MRCP) sequences: single-shot rapid acquisition with relaxation enhancement (RARE) and multislice half-Fourier acquisition single-shot turbo spin echo (HASTE) in imaging the pancreaticobiliary system. PATIENTS AND METHODS: The diagnostic accuracy of single-shot RARE and multislice HASTE was studied in 34 subjects who had undergone conventional cholangiopancreatography. Overall image quality, duct conspicuity, image artifact, signal intensity and contrast-to-noise ratios were assessed independently by two radiologists who were unaware of the underlying diagnosis. RESULTS: Both sequences had comparable diagnostic accuracy regarding a normal biliary system, choledocholithiasis, extra-hepatic and intra-hepatic strictures. Single-shot RARE was superior to multislice HASTE in diagnosing a normal pancreatic system, pancreatic and intrahepatic duct strictures, while providing significantly better image quality (mean {+-} SE 3.7 {+-} 0.07 vs 3.3 {+-} 0.08: P = 0.02) and significantly less image artifact (mean {+-} SE 3.6 {+-} 0.07 vs 3.2 {+-} 0.08:P = 0.01). Single-shot RARE provided significantly better duct conspicuity regarding the pancreatic duct within the body (2.7 {+-} 0.2 vs 2.1 {+-} 0.2: P = 0.003) and tail (2.4 {+-} 0.2 vs 1.6 {+-} 0.2;P = 0.0001), as well as the intrahepatic ducts (3.0 {+-} 0.1 vs 2.6 {+-} 0.1: P = 0.004) but there was no significant difference regarding the remainder of the biliary tree. CONCLUSION: Single-shot RARE provides superior image quality, duct conspicuity with the added advantage of less image artifact and shorter acquisition time. However, volume averaging can cause common bile duct stones to be missed. Therefore, multislice HASTE sequences should still be acquired if choledocholithiasis is suspected. Larger studies are required to assess the diagnostic efficacy of single-shot RARE sequences in pancreatic duct and intra-hepatic duct disease

  9. Metropolis-Hastings Algorithms in Function Space for Bayesian Inverse Problems

    KAUST Repository

    Ernst, Oliver

    2015-01-07

    We consider Markov Chain Monte Carlo methods adapted to a Hilbert space setting. Such algorithms occur in Bayesian inverse problems where the solution is a probability measure on a function space according to which one would like to integrate or sample. We focus on Metropolis-Hastings algorithms and, in particular, we introduce and analyze a generalization of the existing pCN-proposal. This new proposal allows to exploit the geometry or anisotropy of the target measure which in turn might improve the statistical efficiency of the corresponding MCMC method. Numerical experiments for a real-world problem confirm the improvement.

    Science.gov (United States)

    Erdoğmuş, Beşir; Bozkurt, Mahmut; Bakir, Zeki

    2004-12-01

    To compare the diagnostic value of static-liquid magnetic resonance urography (MRU) in T2-weighted HASTE (half-fourier acquisition single-shot turbo spinecho) sequences and T1-weighted excretory MRU with i.v. diuretic and contrast material injection. The study included 29 patients (15 men, 14 women). Thirty-one urinary obstructions were detected on intravenous urography (IVU) two of which were due to bilateral obstructions. The cases were evaluated by T2 HASTE sequences combined with T1-weighted FLASH 3D sequences after i.v. diuretics and gadolinium DTPA injection. Thirty-one urinary obstructions were detected on IVU. Thirty of which were confirmed by T2-weighted MRU and all were confirmed by excretory MRU. In one nonobstructive case, unilateral grade 1 ureteropelvicaliectasis related to ureteral stone was falsely interpreted by both sequences. There were no statistical differences among IVU, T2-weighted MRU and excretory MRU in detecting the obstruction levels. In 22 cases with ureteral stones, 12 of which were confirmed by T2-weighted MRU and 18 cases were confirmed by excretory MRU. Sensitivity and specificity fo detecting the ureteral stones as a cause of obstruction with T2-weighted MRU were 50%and 89% and with excretory MRU were 77% and 89% respectively. In 9 obstructive cases due to causes other than the stones, 8 of which were detected by T2-weighted MRU and all of which were detected by excretory MRU. Sensitivity and specificity for detecting the causes other than the stones with T2-weighted MRU were 96% and 100% and with excretory MRU were 100% and 100% respectively. MRU is a useful thechnique revealing high-quality images to determine the urinary system obstructions to obtain the causes of obstructions. MRU should be used as an alternative imaging technique in cases which IVU can not be applied. The existence and the causes of obstruction can be detected by HASTE MRU. Excretory MRU can supply additional information in cases with functional kidneys where

  14. A Monte Carlo Metropolis-Hastings Algorithm for Sampling from Distributions with Intractable Normalizing Constants

    KAUST Repository

    2013-08-01

    Simulating from distributions with intractable normalizing constants has been a long-standing problem inmachine learning. In this letter, we propose a new algorithm, the Monte Carlo Metropolis-Hastings (MCMH) algorithm, for tackling this problem. The MCMH algorithm is a Monte Carlo version of the Metropolis-Hastings algorithm. It replaces the unknown normalizing constant ratio by a Monte Carlo estimate in simulations, while still converges, as shown in the letter, to the desired target distribution under mild conditions. The MCMH algorithm is illustrated with spatial autologistic models and exponential random graph models. Unlike other auxiliary variable Markov chain Monte Carlo (MCMC) algorithms, such as the Møller and exchange algorithms, the MCMH algorithm avoids the requirement for perfect sampling, and thus can be applied to many statistical models for which perfect sampling is not available or very expensive. TheMCMHalgorithm can also be applied to Bayesian inference for random effect models and missing data problems that involve simulations from a distribution with intractable integrals. © 2013 Massachusetts Institute of Technology.

    Liang, Faming; Kim, Jinsu; Song, Qifan

    2016-01-01

    Markov chain Monte Carlo (MCMC) methods have proven to be a very powerful tool for analyzing data of complex structures. However, their computer-intensive nature, which typically require a large number of iterations and a complete scan of the full dataset for each iteration, precludes their use for big data analysis. In this paper, we propose the so-called bootstrap Metropolis-Hastings (BMH) algorithm, which provides a general framework for how to tame powerful MCMC methods to be used for big data analysis; that is to replace the full data log-likelihood by a Monte Carlo average of the log-likelihoods that are calculated in parallel from multiple bootstrap samples. The BMH algorithm possesses an embarrassingly parallel structure and avoids repeated scans of the full dataset in iterations, and is thus feasible for big data problems. Compared to the popular divide-and-combine method, BMH can be generally more efficient as it can asymptotically integrate the whole data information into a single simulation run. The BMH algorithm is very flexible. Like the Metropolis-Hastings algorithm, it can serve as a basic building block for developing advanced MCMC algorithms that are feasible for big data problems. This is illustrated in the paper by the tempering BMH algorithm, which can be viewed as a combination of parallel tempering and the BMH algorithm. BMH can also be used for model selection and optimization by combining with reversible jump MCMC and simulated annealing, respectively.

    Considering the centrality of subjectivism in modern philosophy, this article attempts to explain subject in Tractatus according to David Pears. A review of Wittgenstein’s earlier teachings reveals that he considers a fundamental limitation for language. The subject serves as a point of view from which the language can be understood. The subject is the presupposition of understanding. Another way of putting this would be to say that any experience is understood from a point of view which is not represented in that experience. Regarding this, it seems that earlier Wittgenstein is somehow subjectivist. This specific form of subjectivism is different from Kantian subjectivism.

Galton, and Ernest Waterlow, and the other is about the nature of medical representations and of Ferrier's illustrations in particular. Medical illustrations are characterized either as pictures, line drawings, or brain maps. Ferrier's illustrations will be shown to be increasingly sophisticated brain maps that contrast with early nineteenth-century standards of medical illustrations, as exemplified by John Bell (1763-1829). © 2013 Elsevier B.V.

  7. A Sanctuary for Science: The Hastings Natural History Reservation and the Origins of the University of California's Natural Reserve System.

    Alagona, Peter S

    2012-01-01

    In 1937 Joseph Grinnell founded the University of California's (U.C.) first biological field station, the Hastings Natural History Reservation. Hastings became a center for field biology on the West Coast, and by 1960 it was serving as a model for the creation of additional U.C. reserves. Today, the U.C. Natural Reserve System (NRS) is the largest and most diverse network of university-based biological field stations in the world, with 36 sites covering more than 135,000 acres. This essay examines the founding of the Hastings Reservation, and asks how it managed to grow and develop, in the 1940s and 1950s, during a time of declining support for natural history research. It shows how faculty and staff courted the support of key institutional allies, presented themselves as the guardians of a venerable tradition in nature study, and emphasized the station's capacity to document ecological change and inform environmental policy and management. In the years since, Hastings and other U.C. reserves have played crucial roles in California environmental politics. Biological field stations in the post-war era deserve more attention not only from historians of biology, but also from environmental historians and other scholars interested in the role of science in society.

  8. Metropolis–Hastings thermal state sampling for numerical simulations of Bose–Einstein condensates

    Grišins, Pjotrs; Mazets, Igor E.

    2014-01-01

    We demonstrate the application of the Metropolis–Hastings algorithm to sampling of classical thermal states of one-dimensional Bose–Einstein quasicondensates in the classical fields approximation, both in untrapped and harmonically trapped case. The presented algorithm can be easily generalized to higher dimensions and arbitrary trap geometry. For truncated Wigner simulations the quantum noise can be added with conventional methods (half a quantum of energy in every mode). The advantage of the presented method over the usual analytical and stochastic ones lies in its ability to sample not only from canonical and grand canonical distributions, but also from the generalized Gibbs ensemble, which can help to shed new light on thermodynamics of integrable systems.

    2011-03-01

    We present a simple, efficient, and computationally cheap sampling method for exploring an un-normalized multivariate density on ℝ(d), such as a posterior density, called the Polya tree sampler. The algorithm constructs an independent proposal based on an approximation of the target density. The approximation is built from a set of (initial) support points - data that act as parameters for the approximation - and the predictive density of a finite multivariate Polya tree. In an initial "warming-up" phase, the support points are iteratively relocated to regions of higher support under the target distribution to minimize the distance between the target distribution and the Polya tree predictive distribution. In the "sampling" phase, samples from the final approximating mixture of finite Polya trees are used as candidates which are accepted with a standard Metropolis-Hastings acceptance probability. Several illustrations are presented, including comparisons of the proposed approach to Metropolis-within-Gibbs and delayed rejection adaptive Metropolis algorithm.

    We demonstrate the application of the Metropolis-Hastings algorithm to sampling of classical thermal states of one-dimensional Bose-Einstein quasicondensates in the classical fields approximation, both in untrapped and harmonically trapped case. The presented algorithm can be easily generalized to higher dimensions and arbitrary trap geometry. For truncated Wigner simulations the quantum noise can be added with conventional methods (half a quantum of energy in every mode). The advantage of the presented method over the usual analytical and stochastic ones lies in its ability to sample not only from canonical and grand canonical distributions, but also from the generalized Gibbs ensemble, which can help to shed new light on thermodynamics of integrable systems.

    Between December 1982 and June 1986, 98 displaced subcapital femoral neck fractures were treated using the Charnley-Hastings bipolar hemiarthroplasty. Although the patients were elderly, often with associated medical problems, the operation was well tolerated and the mortality at one and six months was 14.4% and 24.5% respectively. Fifty-four hips were reviewed after an average follow-up of 33 months; 64.8% of patients had a good or excellent result. The fair or poor results were seen mainly in patients with poor pre-operative mobility and multiple medical problems. A significant cause of morbidity was dislocation (two interprosthetic) which occurred in six hips. There were two cases of deep sepsis but neither patient was fit for further surgery. There were no cases of acetabular erosion requiring revision surgery.

    To compare the feasibility of gadolinium-enhanced excretory MR urography (GEMRU) and conventional MR urography using the half-Fourier acquisition single-shot turbo spin-echo (HASTE) sequence in patients with hydronephrosis or non-visualized kidney. Fifteen patients with hydronephrosis or non-visualized kidney, as demonstrated by ultrasonography or intravenous urography, were enrolled in this study. Nine were men and six were women, and their age ranged from 18 to 77 (mean, 60.6) years. For all MR examinations, a 1.5T MR unit was employed. For breath-hold MR urography, the HASTE technique (MRU) was used, and reconstruction involved the use of a maximum intensity-projection (MIP) algorithm. For gadolinium-enhanced excretory MR urography, the fast low angle shot (FLASH) 3-D method was used and images were obtained at 5, 10, 20, and 30 minutes, and reconstruction again involved the use of MIP algorithm. In some cases, additional GEMRU was obtained 24 hour after contrast material injection, and an MIP algorithm was used for reconstruction. MRU and GEMRU were independently interpreted by two radiologists who for quantitative analysis compared SNR with CNR, and at each anatomic level qualitatively analyzed morphologic accuracy and diagnostic value of the lesions. In quantitative analysis, SNR and CNR differences between the two sequences at the renal pelvis and the level of the ureter were not significant (p greater than 0.05). In qualitative analysis, GEMRU was superior to MRU for the assessment of evaluated ureter at each level (p less than 0.05), anatomic anomaly and intrinsic tumor. Ureteral stones, however, were more easily diagnosed with MRU. For assessment of the ureter GEMRU is superior to MRU and has the advantage of evaluating renal function. We believe that for evaluation of the urinary tract, especially the distal ureter, GEMRU may be a valuable adjunct to routine MR urography. (author)

  15. Subject in Tractatus according to David Pears

    M Hoseinzadeh Yazdi

    2013-02-01

    Full Text Available Subjectivism is viewed as one of the most fundamental underpinnings of modern philosophy. In modern philosophy, subject takes up a new position in human knowledge. The formation of the concept of subject is a decisive turn with which the modern philosophy starts. Considering the centrality of subjectivism in modern philosophy, this article attempts to explain subject in Tractatus according to David Pears. A review of Wittgenstein’s earlier teachings reveals that he considers a fundamental limitation for language. The subject serves as a point of view from which the language can be understood. The subject is the presupposition of understanding. Another way of putting this would be to say that any experience is understood from a point of view which is not represented in that experience. Regarding this, it seems that earlier Wittgenstein is somehow subjectivist. This specific form of subjectivism is different from Kantian subjectivism.

    Presents an obituary for David L. Rosenhan (1929-2012). A distinguished psychologist and professor emeritus at Stanford University, Rosenhan died February 6, 2012, at the age of 82, after a long illness. Born in Jersey City, New Jersey, on November 22, 1929, he received a bachelor's degree in mathematics (1951) from Yeshiva College and a master's degree in economics (1953) and a doctorate in psychology (1958) from Columbia University. A professor of law and of psychology at Stanford University from 1971 until his retirement in 1998, Rosenhan was a pioneer in applying psychological methods to the practice of law, including the examination of expert witnesses, jury selection, and jury deliberation. A former president of the American Psychology-Law Society and of the American Board of Forensic Psychology, Rosenhan was a fellow of the American Association for the Advancement of Science, of the American Psychological Association, and of the American Psychological Society. Before joining the Stanford Law School faculty, he was a member of the faculties of Swarthmore College, Princeton University, Haverford College, and the University of Pennsylvania. He also served as a research psychologist at the Educational Testing Service. As generations of Stanford students can attest, David Rosenhan was a spellbinding lecturer who managed to convey the sense that he was speaking to each individual, no matter how large the group. To his graduate students, he was consistently encouraging and optimistic, always ready to share a joke or story, and gently encouraging of their creativity and progressive independence as researchers. The lessons he cared most about offering, in the classroom as in his research, were about human dignity and the need to confront abuse of power and human frailties. © 2013 APA, all rights reserved.

    The FAIR-HASTE method is a kind of noninvasive perfusion MR imaging obtained without the use of contrast media. By subtracting a flow-insensitive image from a flow-sensitive image, contrast enhancement of inflowing blood achieved. In the present study, we applied pulmonary perfusion FAIR-HASTE sequence for 23 patients with various pulmonary diseases, and compared the findings with those by pulmonary perfusion scintigraphy and Gadolinium perfusion MRI. Pulmonary perfusion imaging with the FAIR-HASTE method was possible in all clinical cases, and the findings corresponded well to those obtained by perfusion MRI using contrast media or pulmonary scintigraphy. The FAIR-HASTE method is a promising method for the evaluation of pulmonary perfusion. (author)

    2011-12-01

    David L. Band, of Potomac Maryland, died on March 16, 2009 succumbing to a long battle with spinal cord cancer. His death at the age of 52 came as a shock to his many friends and colleagues in the physics and astronomy community. Band showed an early interest and exceptional aptitude for physics, leading to his acceptance at the Massachusetts Institute of Technology as an undergraduate student in 1975. After graduating from MIT with an undergraduate degree in Physics, Band continued as a graduate student in Physics at Harvard University. His emerging interest in Astrophysics led him to the Astronomy Department at the Harvard Smithsonian Center for Astrophysics (CfA), where he did his dissertation work with Jonathan Grindlay. His dissertation (1985) entitled "Non-thermal Radiation Mechanisms and Processes in SS433 and Active Galactic Nuclei" was "pioneering work on the physics of jets arising from black holes and models for their emission, including self-absorption, which previewed much to come, and even David's own later work on Gamma-ray Bursts," according to Grindlay who remained a personal friend and colleague of Band's. Following graduate school, Band held postdoctoral positions at the Lawrence Livermore Laboratory, the University of California at Berkeley and the Center for Astronomy and Space Sciences at the University of California San Diego where he worked on the BATSE experiment that was part of the Compton Gamma Ray Observatory (CGRO), launched in 1991. BATSE had as its main objective the study of cosmic gamma-ray bursts (GRBs) and made significant advances in this area of research. Band became a world-renowned figure in the emerging field of GRB studies. He is best known for his widely-used analytic form of gamma-ray burst spectra known as the "Band Function." After the CGRO mission ended, Band moved to the Los Alamos National Laboratory where he worked mainly on classified research but continued to work on GRB energetics and spectra. When NASA planned

  1. Chaos control of Hastings-Powell model by combining chaotic motions

    Science.gov (United States)

    Danca, Marius-F.; Chattopadhyay, Joydev

    2016-04-01

    In this paper, we propose a Parameter Switching (PS) algorithm as a new chaos control method for the Hastings-Powell (HP) system. The PS algorithm is a convergent scheme that switches the control parameter within a set of values while the controlled system is numerically integrated. The attractor obtained with the PS algorithm matches the attractor obtained by integrating the system with the parameter replaced by the averaged value of the switched parameter values. The switching rule can be applied periodically or randomly over a set of given values. In this way, every stable cycle of the HP system can be approximated if its underlying parameter value equalizes the average value of the switching values. Moreover, the PS algorithm can be viewed as a generalization of Parrondo's game, which is applied for the first time to the HP system, by showing that losing strategy can win: "losing + losing = winning." If "loosing" is replaced with "chaos" and, "winning" with "order" (as the opposite to "chaos"), then by switching the parameter value in the HP system within two values, which generate chaotic motions, the PS algorithm can approximate a stable cycle so that symbolically one can write "chaos + chaos = regular." Also, by considering a different parameter control, new complex dynamics of the HP model are revealed.

    To determine the efficacy of flow-sensitive alternating inversion recovery using half-Fourier single-shot turbo spin-echo (FAIR-HASTE) in detecting cerebral hypoperfusion in chronic carotid occlusive disease, we subjected 12 patients with various degrees of cervical internal carotid artery stenoses and/or occlusion (Stenosis group) and 24 volunteers (Normal group) to FAIR-HASTE. In addition, 10 out of 12 patients in the Stenosis group underwent dynamic susceptibility contrast-perfusion magnetic resonance imaging (DSC-pMRI) before and after revascularization in the dominantly affected side. The absolute asymmetry indexes (AIs) of both cerebral hemispheres in the Normal and Stenosis groups were compared in FAIR-HASTE. In addition, the AIs were compared with those in the Stenosis group before and after revascularization in both FAIR-HASTE and regional cerebral blood flow (rCBF), calculated with DSC-pMRI. A statistically significant difference was recognized between the AIs in the Normal and Stenosis groups (AI=2.25±1.92, 8.09±4.60, respectively; p<0.0001). Furthermore, in the Stenosis group the AIs on both FAIR-HASTE (8.88±4.93, 2.22±1.79, respectively; p=0.0003) and rCBF (7.13±3.57, 1.25±1.33, respectively; p=0.0003) significantly decreased after revascularization. In the Stenosis group, before revascularization, signal intensity on both FAIR-HASTE and rCBF had a tendency to be lower in the dominantly affected side. FAIR-HASTE imaging was useful in the detection and evaluation of cerebral hypoperfusion in chronic occlusive carotid disease. (author)

    2004-12-01

    David Fulmer Bender died in San Diego, California, on 13 September 2004, at the age of 91. His heart stopped suddenly while he was dancing. His pioneering work in establishing comprehensive, computer-accessible ephemerides of asteroids and comets found many applications, including the first-ever visit to an asteroid, Gaspra, by an interplanetary spacecraft. Dave was born in Reno, Nevada, on 10 February 1913, to Homer Charles Bender and Susan Bowers Bender. The family moved to Spokane, Washington, while Dave was very young. His father was a civil engineer and a graduate of MIT, who helped design bridges and dams throughout the Northwest, including the Grand Coolie Dam. Dave had a brother, Phillip (now deceased), who was one year younger. Advancing rapidly in the Spokane school system, Dave finished high school when he was 15 years old. At 16 he moved to Pasadena, California, and began his studies at the California Institute of Technology (Caltech). In addition to pursuing his course work, he was active in track and football, a tendency toward physical exercise that stayed with him for the rest of his life. It was probably during these years that Dave heard a lecture by Albert Einstein, as mentioned to colleagues many years later. Dave received a BS degree in physics in 1933, an MS in 1934, and a PhD in 1937, all from Caltech. His dissertation was entitled, "The Index of Refraction of Air in the Photographic Infrared." During his sophomore year he found his way to Pomona College in Claremont, California, where he met his future wife, Elizabeth Boyden at a social gathering. They were married in 1935. Dave's academic career spanned the years from 1937 to 1970, initially at Louisiana State University, Vanderbilt University, and then Fisk. As a life-long pacifist and conscientious objector, Dave served alternate duty during World War II. In 1946 he joined the faculty of the physics department at Whittier College in California, where he became the department chair and

    How deeply honoured I am to have the opportunity to express my thoughts at this delightful celebration of David's achievements, so far, in his remarkable career. I have been asked to center my remarks on David's contributions to the mentoring and professional development of scientists early in their careers. This is a topic that I am more than happy to reflect on, because it gives me the opportunity to recall the exciting period I spent as one of David's postgraduate students at Imperial College in the early 1980s. It also gives me the chance to publicly express my gratitude to David for the opportunities he created for me at that time, as well as for the interest and care he has shown in my career and well-being ever since, as we have met up and exchanged news and ideas around the world: in New Mexico and Colorado, in Cancun, Paris and Trieste, at numerous March Meetings of the American Physical Society and, of course in London, Oxford, and my home town, Champaign-Urbana, location of the University of Illinois. I have been a member of David's circle for 25 years now, and I would like to tell you a little about how this came to be. Not because of what this says about me, but, rather, because of what it tells you about David and the rich generosity of his spirit and effort when it comes to supporting the underdog. I was indeed one such underdog—and that's putting it charitably—when I first met David in September of 1982, not long before the academic year was to begin. I had heard about the exciting circle of physical and mathematical ideas swirling around the spin glass question during the previous year, which I had spent at the University of California's Los Angeles campus, through an opportunity kindly arranged, as it happens, by Sam Edwards. But I was eager to return to the UK for postgraduate studies and to work on spin glasses, so I simply showed up at David's Imperial College office, unannounced (if I remember correctly). And with his characteristic

    To evaluate the image quality of two fast dynamic magnetic resonance imaging (MRI) sequences: True fast imaging with steady state precession (TrueFisp) was compared with half-Fourier acquired single turbo-spin-echo (HASTE) sequence for the characterization of velopharyngeal insufficiency (VPI) in repaired cleft palate patients. Twenty-two patients (10 female and 12 male; mean age, 17.7 ± 10.6 years; range, 9-31) with suspected VPI underwent 3-T MRI using TrueFisp and HASTE sequences. Imaging was performed in the sagittal plane at rest and during phonation of ''ee'' and ''k'' to assess the velum, tongue, posterior pharyngeal wall and a potential VP closure. The results were analysed independently by one radiologist and one orthodontist. HASTE performed better than TrueFisp for all evaluated items, except the tongue evaluation by the orthodontist during phonation of ''k'' and ''ee''. A statistically significant difference in favour of HASTE was observed in assessing the velum at rest and during phonation of ''k'' and ''ee'', and also in assessing VP closure in both raters (p < 0.05). TrueFisp imaging was twice as fast as HASTE (0.36 vs. 0.75 s/image). Dynamic HASTE images were of superior quality to those obtained with TrueFisp, although TrueFisp imaging was twice as fast.

As inflorescências produzidas do tratamento sob omissão de N apresentaram coloração laranja-pálido e deformação nas hastes florais. O comprimento e o diâmetro da haste floral e o comprimento da inflorescência foram reduzidos nos tratamentos com omissão de N, P ou K em até 31,23%, em relação ao tratamento completo. A massa de matéria seca e a durabilidade pós-colheita das hastes florais foram reduzidas em 67 e 38,46%, respectivamente, em ambos os tratamentos com omissão de N ou K. As deficiências desses macronutrientes reduziram, ainda, a produção de hastes florais, a partir do segundo perfilho emitido. Hastes florais com maior massa de matéria seca e diâmetro apresentaram maior durabilidade pós-colheita. O teor de carboidrato na parte subterrânea mostrou correlação positiva (0,90 com a massa de matéria seca das hastes florais. Hastes florais com maior teor de carboidratos solúveis nas folhas retardaram a emissão da inflorescência.The objective of this work was to evaluate Heliconia psittacorum x H. spathocircinata Aristeguieta 'Golden Torch' first flower stem morphological and physiological characteristics as well as postharvest longevity, under macronutrients omissions.

    Full Text Available David Tuveson, Director of the Cancer Center at Cold Spring Harbor Laboratory, is a clinician-scientist with a longstanding interest in understanding and treating pancreatic cancer. Since developing the first mouse model of pancreatic cancer in 2002, the Tuveson lab has made a series of discoveries that shed light on the molecular drivers of this disease and provide promising therapeutic avenues for a malignancy that is notoriously challenging to treat. In collaboration with Hans Clevers, David developed the first pancreatic cancer organoids, which revolutionized the field by providing a powerful model system for basic discoveries and advancement of personalized medicine. Here, David talks to Ross Cagan about his path from chemistry student to world-renowned oncologist, highlighting how his colleagues, mentors and patient interactions shaped his research interests and unique approach to scientific discovery. As well as discussing the story behind some of his breakthroughs, he provides tips on running a lab and succeeding in or outside academia.

    Directory of Open Access Journals (Sweden)

    Paolo Sebastiano Lanzi

    2013-02-01

    Full Text Available L’opera di David Lynch non si limita al cinema, come ha dimostrato l’esposizione del 2007 alla Fondation Cartier di Parigi, The Air is on Fire. Tuttavia gli studi teorici hanno trascurato ciò che gallerie e musei hanno evidenziato da tempo: il Lynch pittore, fotografo, musicista, artista poliedrico. L’articolo si focalizza su una serie fotografica, Snowmen, ed è tratto da una ricerca di Paolo Sebastiano Lanzi sulla figura di David Lynch fotografo. Alla luce del saggio di Freud sul Perturbante (Das Unheimliche, 1919 si interpretano gli Snowmen come immagini di morte. Si chiariscono alcuni aspetti della poetica dell’artista-regista, come l’inquietudine dell’Inland Empire o di certe idee care al Surrealismo. Lo studio della produzione fotografica di Lynch riempie un vuoto nell’analisi critica sul suo lavoro, che va necessariamente riconsiderato in una prospettiva più ampia.

    Interpretations of the narratives about David in the Books of Samuel can be divided roughly into works that understand them one way or the other as products of history, and works that tend to disregard questions about their historical conditions. But neither strategy – studying the meaning...... of their production in terms of history, or not at all – can bring out all facets in the meaning of producing these narratives. Here a spatial approach is taken, according to which the production of literature is not simply caused by historical contexts that can be accounted for in research; it takes place...... in unresolved social situations of which the authors are not in control. From this perspective, some nuances are suggested about how the writing of the David narratives could be meaningful to their author(s)....

    Purpose: To evaluate gadolinium-enhanced T{sub 1}-weighted excretory MR urography (EMRU) versus T{sub 2}-weighted (HASTE) MR urography in children with upper urinary tract abnormalities. Patients and Methods: In a prospective study 63 children, aged from 3 weeks to 15 years, underwent MR urography in a 1.5-T scanner. Before and after an intravenous injection of 0.05 mg/kg body weight of furosemide, respiratory-triggered HASTE images were obtained for T{sub 2}-weighted MR urography. EMRU was performed subsequent to i.v. gadolinium injection with respiratory-gated, coronal 3D-gradient-echo sequences. Results: Compared to T{sub 2}-weighted (HASTE) MR urography, gadolinium-enhanced MR urography revealed a superior diagnostic accuracy in non-dilated collecting systems (horseshoe kidneys, ectopic kidneys, duplex systems, single ectopic ureters, ureteroceles). EMRU and T{sub 2}-weighted (HASTE) MRU turned out to be equivalent in the assessment of obstructed but normal functioning upper urinary tracts (UPJ obstructions, megaureters). Non-functioning dilated collecting systems and multicystic dysplastic kidneys were best visualized with use of T{sub 2}-weighted (HASTE) MR urography. Conclusion: Respiratory-gated gadolinium-enhanced T{sub 1}-weighted MRU allows accurate evaluation of most upper urinary tract abnormalities. T{sub 2}-weighted (HASTE) MRU complements GMRU in the evaluation of non-functioning renal units and cystic disease of the kidneys. (orig.)

  14. The Metropolis-Hastings algorithm, a handy tool for the practice of environmental model estimation : illustration with biochemical oxygen demand data

    Directory of Open Access Journals (Sweden)

    Franck Torre

    2001-02-01

    Full Text Available Environmental scientists often face situations where: (i stimulus-response relationships are non-linear; (ii data are rare or imprecise; (iii facts are uncertain and stimulus-responses relationships are questionable. In this paper, we focus on the first two points. A powerful and easy-to-use statistical method, the Metropolis-Hastings algorithm, allows the quantification of the uncertainty attached to any model response. This stochastic simulation technique is able to reproduce the statistical joint distribution of the whole parameter set of any model. The Metropolis-Hastings algorithm is described and illustrated on a typical environmental model: the biochemical oxygen demand (BOD. The aim is to provide a helpful guideline for further, and ultimately more complex, models. As a first illustration, the MH-method is also applied to a simple regression example to demonstrate to the practitioner the ability of the algorithm to produce valid results.

    Full Text Available Flores de zínia (Zinnia elegans Jacq. são adaptadas às condições climáticas da Região Sudeste do País, com excelente potencial para a comercialização como flor de corte. O presente trabalho objetivou avaliar a influência da sacarose aplicada na forma de solução de condicionamento, e do corte periódico da base das hastes sobre a longevidade e absorção de água pelas flores. Hastes florais uniformizadas em tamanho foram submetidas ao condicionamento, por seis horas, com sacarose a 5, 10, 15 e 20% ou com soluções de 10% de sacarose por 0, 6, 12, 18 e 24 horas, com ou sem cortes periódicos na base das hastes a cada 48 horas. O tratamento das flores por seis horas com sacarose a 5, 10, 15 ou 20% não afetou a longevidade das flores, comparado àquelas mantidas somente com água destilada. O corte periódico da base das hastes promoveu melhor suprimento de água às flores, estendendo a longevidade. O condicionamento das flores com 10% de sacarose por 18 ou 24 horas acelerou a senescência das flores em vaso. A taxa de produção de etileno foi inibida pelo aumento da concentração de sacarose na solução de condicionamento.

  16. Finite Adaptation and Multistep Moves in the Metropolis-Hastings Algorithm for Variable Selection in Genome-Wide Association Analysis

    Science.gov (United States)

    Peltola, Tomi; Marttinen, Pekka; Vehtari, Aki

    2012-01-01

    High-dimensional datasets with large amounts of redundant information are nowadays available for hypothesis-free exploration of scientific questions. A particular case is genome-wide association analysis, where variations in the genome are searched for effects on disease or other traits. Bayesian variable selection has been demonstrated as a possible analysis approach, which can account for the multifactorial nature of the genetic effects in a linear regression model. Yet, the computation presents a challenge and application to large-scale data is not routine. Here, we study aspects of the computation using the Metropolis-Hastings algorithm for the variable selection: finite adaptation of the proposal distributions, multistep moves for changing the inclusion state of multiple variables in a single proposal and multistep move size adaptation. We also experiment with a delayed rejection step for the multistep moves. Results on simulated and real data show increase in the sampling efficiency. We also demonstrate that with application specific proposals, the approach can overcome a specific mixing problem in real data with 3822 individuals and 1,051,811 single nucleotide polymorphisms and uncover a variant pair with synergistic effect on the studied trait. Moreover, we illustrate multimodality in the real dataset related to a restrictive prior distribution on the genetic effect sizes and advocate a more flexible alternative. PMID:23166669

    Full Text Available David Kasner, MD (1927–2001, used his extensive dissections of eye bank eyes and experiences in teaching cataract surgery to resident physicians to realize that excision of vitreous when present in the anterior chamber of eyes undergoing cataract surgery was preferable to prior intraoperative procedures. Noting that eyes tolerated his maneuvers, he then performed planned subtotal open-sky vitrectomies; first on a traumatized eye in 1961, then on two eyes of patients with amyloidosis (1966–1967. The success of these operations was noted by others, most particularly Robert Machemer, MD. Kasner's work directly led to further surgical developments, including closed pars plana vitrectomy.

    1993-01-01

    The attitudes of 211 students at a university in Mississippi were investigated both before and after seeing the Public Broadcasting Film Who Is David Duke? The film provided evidence of Duke's current racism, anti-Semitism, and pro-Nazi leanings. In a previous study with university students in Louisiana, the majority did not change their attitudes after watching the film (Eisenman, 1993). However, in the present study, students' attitudes showed change in an anti-Duke direction. The findings are discussed and reasons given for the differences between the two samples, and for the popularity of Duke, a former leader of the Ku Klux Klan.

  2. The Will to Touch: David Copperfield’s Hand

    Directory of Open Access Journals (Sweden)

    Pamela K. Gilbert

    2014-10-01

    Full Text Available In the nineteenth century, touch was considered to be a more privileged sense than has been generally noted, and the hand was pre-eminently the site of active touching. The hand comes newly to rival the face in descriptive significance in mid-nineteenth-century fiction, and reflects contemporary notions of the role of touch in the exercise of the will and the development of the sensorium. This article explores medical and philosophical understandings of embodied touch within the period, and examines why the hand emerged as a focal point for scientific, poetic, and popular discussion. Such scientists as Charles Bell, Herbert Spencer, and Alexander Bain tend to work within two paradigms: the hand as a site of sensory input that forms a conduit between inner and outer worlds, and the hand as an instrument of the will. The article explores Dickens's use of these ideas about touch and development in his 1850 'Bildungsroman', 'David Copperfield'. David struggles to establish his proper status as a middle-class male, in part by learning to use his hands to impose his own will and to resist the dominance of inappropriate others through touch.

    The aim of this study was to investigate the effect of dredging intensity on the physical and biological recovery times of the seabed following marine aggregate dredging. Two areas of seabed, previously subject to, respectively, relatively high and lower levels of dredging intensity, were identified on the Hastings Shingle Bank. Two reference areas were also selected for comparative purposes. All four sites were monitored annually over the period 2001-2004, using a combination of acoustic, video and grab sampling techniques. Since the site was last dredged in 1996, this was intended to provide a sequence of data 5-8 years after cessation of dredging. However, an unexpected resumption of dredging within the high intensity site, during 2002 and 2003, allowed an additional assessment of the immediate effects and aftermath of renewed dredging at the seabed. The early stages of recovery could then be assessed after dredging ceased in 2003. Results from both dredged sites provide a useful insight into the early and latter stages of physical and biological recovery. A comparison of recent and historic dredge track features provided evidence of track erosion. However, tracks were still visible 8 years after the cessation of dredging. Within the high dredging intensity site, recolonisation was relatively rapid after the cessation of dredging in 2003. Rather than indicating a full recovery, we suggest that this initial 'colonization community' may enter a transition phase before eventually reaching equilibrium. This hypothesis is supported by results from the low intensity site, where biological recovery was judged to have taken 7 years. Further monitoring is needed in order to test this. An alternative explanation is that the rapid recovery may be explained by the settlement of large numbers of Sabellaria spinulosa. As the resumption of dredging within the high intensity site limited our assessment of longer-term recovery it is not yet possible to assume that a 7-year

    2004-12-01

    Full Text Available Among all the great philosophers, David Hume has the rare merit of joining to a properly philosophical work an equally important output as historian. According to him, the interpretation of history by means of the general principles of political theory must not be guided by ethical or normative considerations, as when judging historic events according to what things ought to be, for instance, in view of the best government, but it should be restricted to explain the exercise of power in the different times, just as it can be established by the testimony of the sources. Only this methodological attitude allows us to avoid the partisan interpretations that try to justify the present by the past, instead of investigating it to corroborate the most appropriate explanation.

    Mitte des 20. Jahrhunderts entwickelten David Bohm und Richard Feynman zwei grundlegend verschiedene Ansätze der moderne Quantenmechanik: Bohm eine realistische Deutung mit Hilfe verborgener Parameter und Feynman den Pfadintegralformalismus. Dies ist umso bemerkenswerter, weil beide Physiker von ähnlichen Voraussetzungen ausgingen und aus ähnlichen Zusammenhängen stammten. Durch ihren vergleichenden Ansatz bietet diese Studie mehr als einen Beitrag zur Geschichte der Quantentheorie. Mit der Frage nach den sozialen und kulturellen Bedingungen der Theoriebildung ist sie darüberhinaus von wissenschaftssoziologischem und wissenschaftstheoretischem Interesse. Die anfangs ähnliche und später unterschiedliche Einbindung der beiden Wissenschaftler in die Scientific Community erlaubt es überdies zu untersuchen, welchen Anpassungsdruck die jeweilige Gruppe auf den individuellen Wissenschaftler und die Kernbestandteile seiner Forschungen ausübt und welche neuen Freiheitsgrade für die Theoriebildung entstehen, ...

    Throughout his life, David Bohm felt himself to be different, and this was reflected in his lifestyle and in his physics. His life was one of unfulfilled searching. If one compares mainstream physics to the church, with a solid hierarchy of cardinals, archbishops and bishops, Bohm was an ascetic hermit who would occasionally come in from the wilderness with a compelling message, only to disappear again. Bohmian quantum mechanics is not part of mainstream physics, but for those who do cross over, like John Bell, the commitment can be rewarding. In the post-war 'Un-American Activities' purge, Bohm lost a prestigious job at Princeton and t emporarily his US citizenship, and his nomadic career took him to Brazil, Israel and Bristol before he finally settled in London's Birkbeck College. A sensitive-written book about a gifted, unusual and sometimes provocative figure. The interaction between Bohm and Oppenheimer is especially interesting, while Bohm's later life was bizarre.

  8. David Duke, running for governor, proposes tattooing people with HIV.

    Science.gov (United States)

    1995-05-19

    Former Ku Klux Klan leader, David Duke, planning a second run for governor of Louisiana, said he would curb the AIDS epidemic by tattooing people who are infected with HIV. His suggestion is to put indelible, glow-in-the-dark tattoos on the genitals of people infected with HIV. According to Duke, it may sound very draconian but it would not demean people. He also believes that tattooing would be legal because courts have a history of supporting the quarantining and institutionalizing of people with infectious diseases, such as tuberculosis. Duke said Cuba has had some success in using quarantines to reduce HIV infection, but he does not think it would work in the United States because it would cost too much. According to Duke, many people who get HIV from irresponsible behavior do not tell their partners that they have AIDS--these people are mad at the world and engage in dangerous behaviors even more.

The theory refers to a rational law as a way to achieve development in Third World nations, away from the traditional order, but the host of a modern law. The central conception found intentionality and the universality of the rules and, after empirical analysis, the author proved fundamentally flawed due to its ethnocentric and evolutionism , to believe that developing countries only achieve the full development of importing the legal system of the West. In any case, the studies on the social theory of law contributed to the current concept of law and development.

    Directory of Open Access Journals (Sweden)

    Leire Ituarte Pérez

    2017-12-01

    Full Text Available In this article we address a hermeneutic approach to David Fincher’s Fight Club. Inspired by some of the methodological principles of Psychoanalysis and Queer Theory the study tries to thresh the details of the representation of Masculinity in the film. Departing from the hypothesis that such representation in the film is closely linked to the masculine castration anxiety, the essay traces the recurrent and more or less parodic, more or less subliminal allusions to emasculation as well as the fetishistic compensatory strategies displayed. The analysis concludes that the overwhelming mise en scène of the masculine Oedipal scenario in the film pursues to underpin an hegemonic discourse of Masculinity threatened by the taboo of Homosexuality. Hence, the prominent erotisization of masculine masochism reveals itself, in all its ambivalence, as a performative strategy to institutionalise a heteronormative sexual regime.

    To compare the performance of non-contrast MRI with half-Fourier acquisition single-shot turbo spin echo (HASTE) vs. contrast-enhanced MRI/3D-MRCP for assessment of suspected choledocholithiasis in hospitalized patients. 123 contrast-enhanced abdominal MRI/MRCP scans in the hospital setting for possible choledocholithiasis were retrospectively evaluated. Endoscopic retrograde cholangiopancreatography, intraoperative cholangiogram or documented clinical resolution served as the reference standard. Readers first evaluated the biliary tree using coronal and axial HASTE and other non-contrast sequences, and later reviewed the entire exam with post-contrast sequences and 3D-MRCP. Test performance for the image sets was compared for choledocholithiasis, acute hepatitis, cholangitis, and acute cholecystitis. Reader agreement, MRCP image quality, and confidence levels were also assessed. Clinical predictors of age and fever were tested for association with perceived need for contrast in biliary assessment. There were 27 cases of choledocholithiasis, 31 cases of acute hepatitis, 37 cases of acute cholecystitis, and 3 clinically diagnosed cases of acute cholangitis. Both the abbreviated and full contrast-enhanced/MRCP image sets resulted in high accuracy for choledocholithiasis (91.1-94.3% vs. 91.9-92.7%). There was no difference in sensitivity or specificity for either reader for any diagnosis between image sets (p > 0.40). 1 reader showed improved confidence (p choledocholithiasis, performance of non-contrast abdominal MRI with HASTE is similar to contrast-enhanced MRI with 3D-MRCP, offering potential for decreased scanning time and improved patient tolerability.

As alterações de equilíbrio e força muscular decorrentes do envelhecimento, que contribuem para a ocorrência de quedas, podem ser parcialmente revertidas com o exercício físico. Objetivo: Verificar os efeitos de 8 semanas de treinamento de equilíbrio com haste vibratória, sobre o comprimento de passo e a ativação muscular do membro inferior de idosas durante marcha com duplas tarefas. Métodos: Participaram do estudo 16 idosas divididas aleatoriamente em dois grupos: grupo treinamento de equilíbrio (GTE e grupo de treinamento de equilíbrio com haste vibratória (GTEHV. A avaliação da marcha foi composta por três condições distintas que incluiram marcha em velocidade de preferencia e duplas tarefas. Foram coletados os dados eletromiográficos dos músculos reto femoral, vasto lateral, bíceps femoral, tibial anterior e gastrocnêmio lateral, e dados cinemáticos de comprimento de passo. Resultados: O GTEHV apresentou maiores valores de comprimento de passo após o treinamento. Ambos os grupos (GTE e GTEHV mostraram menores valores de ativação muscular após o treinamento. Conclusão: Os resultados sugerem que o treinamento de equilíbrio com haste vibratória pode ser eficaz para melhora do desempenho durante diferentes condições de marcha em idosos, contribuindo para a prevenção de quedas nesta população.

Imediatamente após o surgimento dos sintomas, avaliou-se a doença a cada 10 dias até o final do ciclo, aos 205 dias, calculando-se a porcentagem de hastes infectadas por planta. Calculou-se a área abaixo da curva de progresso para a incidência (AACPI. As curvas de progresso da doença dos tratamentos foram submetidas ao ajuste dos modelos linear, exponencial, monomolecular, logístico e Gompertz. Houve interação significativa de métodos e épocas de plantio na incidência da doença. Constatou-se menor incidência da seca da haste em transplantio de mudas comparado à semeadura direta em todas as épocas de plantio. Verificou-se aumento da incidência proporcionado pelo atraso na época de plantio nos dois métodos. O modelo exponencial foi o que melhor descreveu o comportamento da doença em todos os tratamentos. As diferenças estatísticas entre os tratamentos, considerando a taxa de progresso, não refletiram a intensidade da doença no campo. Na mesma época de plantio, as quantidades inicial e máxima da doença, observadas na semeadura direta, foram superiores aos tratamentos referentes ao transplantio de mudas, coerentes com os valores da AACPI. Registrou-se uma relação direta entre queda de temperatura e aumento da incidência da seca da haste.

    2014-11-01

    Full Text Available In a filmmaking career replete with extraordinary images and sounds, David Lynch's Mulholland Drive (2001 stands out for attention as a striking and seemingly inexhaustible resource for analysis. In this article, this film is used to examine the specific ways in which Lynch uses pre-existing pop songs to wrap the spectator within the filmic soundscape. Nowhere is the complexity and uncanniness of pop music made more explicit than in Rebekah Del Rio's stunning performance of “Llorando (Crying” in the Club Silencio scene. The split between the singer's powerful performance and her subsequent collapse with the sound of the voice left hanging in the air marks a pivotal point in the film. This scene, coupled with other examples of feminine jouissance, is contrasted with the deadening roar of the master's voice, which solely demands obedience but is deaf to any reply. At the core of this article is an analysis of the status of the voice (and the gaze as examples of the Lacanian object a and its relationship to Marx's concept of surplus value. Mulholland Drive provides a powerful demonstration of how these concepts can be seen, heard, and felt in relation to film, and how sound can reverberate into the spaces and silences beyond the screen.

    2013-09-01

    Full Text Available The American Dream is a recurrent theme in American literature. In this response, this paper is an attempt to expose the destructive effects of the dream on human spirits and relations and how it is contradicted in different ways through the analysis of his brilliant play, American Buffalo by David Mamet. Beneath the seeming simple surface of the play lies a deep current of meanings that reflect the calamities of modern American life, and in a broader sense, the modern world. This article indicates how capitalism inculcates ideologies in the mind of individuals in order to facilitate the exploiting process and unquestioning subordination. Ragged individualism, as one of these ideologies, disrupts all communal bonds and even exceeds to the disintegration of friendship and family life. On the other hand, this individualism, as an ideology, is sustained by other capitalist ideologies such as advertising, consumerism and emulation. It will also be discussed that monetary interests are all one seeks in a highly competitive atmosphere and nothing is privileged over business ethics. In brief, this reading of the play tries to illuminate that we live in a dream-like world of ideologies that block logical thinking and forge our relationship with our real existence through less suspected ways.

  4. David Malament and the Conventionality of Simultaneity: A Reply

    Science.gov (United States)

    Grünbaum, Adolf

    2010-10-01

    In 1977, David Malament proved the valuable technical result that the simultaneity relation of standard synchrony ɛ=1/2 with respect to an inertial observer O is uniquely definable in terms of the relation κ of causal connectibility. And he claimed that this definability undermines my own version of the conventionality of metrical simultaneity within an inertial frame. But Malament’s proof depends on the imposition of several supposedly “innocuous” constraints on any candidate for the simultaneity relation relative to O. Relying on Allen I. Janis’s 1983 challenge to one of these constraints, I argue that Malament’s technical result did not undermine my philosophical construal of the ontological status of relative metrical simultaneity. Furthermore, I show that (a) Michael Friedman’s peremptorily substantivalist critique of my conception, which Malament endorses, is ill-founded, and (b) if Malament had succeeded in discrediting my own conventionalist version of metrical simultaneity, he would likewise have invalidated Einstein’s pioneering version of it.

    2015-11-01

    Full Text Available The present paper examines the main biographical traits of the Italian author, politician and Risorgimento activist David Levi (1816-1898. Early in life, Levi abandoned the traditional religious spheres of Judaism but always remained attached to his Jewish heritage, as emerges from his oeuvre. Levi’s relevance derives from his constant effort to amalgamate Italian and Jewish identities in a context of increasing secularity. An analysis of his figure and activities, therefore enables us to investigate some crucial issues at the center of current historiographical debate, such as the nineteenth-century Jewish transition from a traditional to a modern identity, the discussion around the concepts of “assimilation”and “integration,” orientalist researches and the study of religions in nineteenth-century Italy, and the important role of Freemasonry and Saintsimonism in Levi’s secularization modes. In fact, their concept of “Religion of Humanity” helped him to create a synthesis between Enlightenment’s aspirations to universalism and Risorgimento’s cosmopolitan nationalism.

    Directory of Open Access Journals (Sweden)

    2012-11-01

    Full Text Available The research is related to David Hume. This philosopher is described as being an empiricist, but it should be noted that the empiricism promoted by Hume represents the development up to the final consequences of this philosophical doctrine that should be subjected to the observability requirement. The core problem for Hume’s philosophy is the difficulty of causality thinking. The Scottish philosopher promotes a moderate and inconsistent skepticism because he does not doubt the permanency of facts. The Humean epistemology is mixed with elements belonging to some naïve ontology of a materialistic nature and with elements of a sensualistic psychology of an associationist type. The causality or the causal connection between events is based on a psychological belief, which has a pragmatic end for people, in that it offers us the psychological comfort of habitual events and the familiar existential. Causality refers to certain events that have already happened in a certain way, but it cannot constitute a necessary and sufficient basis for similar future events.

    To compare turbo spin-echo (TSE), breath-hold TSE and half-Fourier acquisition single-shot turbo spin-echo (HASTE) sequences quantitatively and qualitatively in T2-weighted images of liver lesions. The authors evaluated prospectively 89 liver lesions in 73 patients using a 1.0-T magnetic resonance system to compare TSE, breath-hold TSE and HASTE sequences. The quantitative parameters were: lesion-to-liver contrast and lesion-to-liver contrast-to-noise ratio. The qualitative analysis was performed by two observers in consensus who examined four parameters: respiratory artifacts, lesion edge definition, intrahepatic vessel definition and image quality. Repeated measures analysis of variance was utilized to compare the quantitative variables and Friedman's nonparametric test for the qualitative parameters. In quantitative terms, the lesion-to-liver contrast was similar in TSE and breath-hold TSE sequences (2.45±1.44 versus 2.60±1.66), both of which were significantly better than the HASTE sequence (1.12±0.72; p<0.001). The lesion-to-liver contrast-to-noise ratio was significantly higher in the TSE sequence (62.60±46.40 versus 40.22±25.35 versus 50.90±32.10 for TSE, breath-hold TSE and HASTE sequences, respectively; p<0.001). In the qualitative comparisons, the HASTE sequence was significantly better than the TSE and breath-hold TSE sequences (p<0.001) in terms of artifacts and definition of lesion edge and intrahepatic vessels. Image quality was also significantly greater in the HASTE sequence (p<0.001). In quantitative terms, the TSE sequence is better than the breath-hold TSE and HASTE sequences, but there are no movement artifacts in the HASTE sequence, which is also significantly superior to TSE and breath-hold TSE sequences in qualitative terms and, thus, can be employed for T2-weighted images in liver studies.

    The database for annotation, visualization and integrated discovery (DAVID), which can be freely accessed at http://david.abcc.ncifcrf.gov/, is a web-based online bioinformatics resource that aims to provide tools for the functional interpretation of large lists of genes/proteins. It has been used by researchers from more than 5000 institutes worldwide, with a daily submission rate of ∼1200 gene lists from ∼400 unique researchers, and has been cited by more than 6000 scientific publications. However, the current web interface does not support programmatic access to DAVID, and the uniform resource locator (URL)-based application programming interface (API) has a limit on URL size and is stateless in nature as it uses URL request and response messages to communicate with the server, without keeping any state-related details. DAVID-WS (web service) has been developed to automate user tasks by providing stateful web services to access DAVID programmatically without the need for human interactions. The web service and sample clients (written in Java, Perl, Python and Matlab) are made freely available under the DAVID License at http://david.abcc.ncifcrf.gov/content.jsp?file=WS.html.

    Full Text Available Estudamos os resultados clínicos e radiográficos de 31 pacientes portadores de fraturas diafisárias do úmero que foram operados com hastes intramedulares. Destes quatro apresentaram fraturas no local da inserção da haste e foram tratados com outro método. Dos 27 pacientes restantes o índice de consolidação foi de 96,1 % e que durou em média de 63,4 dias. Cinco queixaram-se de dor no ombro e em apenas um apresentou limitação da abdução. Paralisia temporária do nervo radial foi constatada em dois pacientes e pseudartrose em um que após 5 meses da cirurgia foi submetido a nova intervenção cirúrgica com o emprego de placa e enxerto ósseo autólogo. Concluímos que embora o emprego de hastes intramedulares bloqueadas apresentou alto índice de a via de acesso retrógrada pode levar a fraturas no seu ponto de entrada e via anterógrada com violação do manguito rotador pode gerar dores no ombro.Clinical and radiographic outcomes of 31 patients with humeral diaphyseal fractures submitted to surgery with intramedullary shafts were studied. From these, four patients presented fractures at the shaft insertion site and were treated using a different method. From the 27 patients left, the healing rate was 96.1%, with an average duration of 63.4 days. Five of them complained of pain in the shoulder and only one presented abduction limitation. Temporary palsy of the radial nerve was found in two patients and pseudoarthrosis in one of them, who was submitted to a new surgical intervention with plate and autologous bone graft, after 5 months. It was concluded that, although blocked intramedullary shafts presents a high incidence of the retrograde access port leading to fractures in its insertion site and the anterograde port causing pain in the shoulder.

    Full Text Available The aim of this study was to explore the applicability of fast MR techniques to routine paediatric abdominopelvic MRI at 1.5 Tesla. “Controlled Aliasing in Parallel Imaging Results in Higher Acceleration-” (CAIPIRINHA- accelerated contrast-enhanced-T1w 3D FLASH imaging was compared to standard T1w 2D FLASH imaging with breath-holding in 40 paediatric patients and to respiratory-triggered T1w TSE imaging in 10 sedated young children. In 20 nonsedated patients, we compared T2w TIRM to fat-saturated T2w HASTE imaging. Two observers performed an independent and blinded assessment of overall image quality. Acquisition time was reduced by the factor of 15 with CAIPIRINHA-accelerated T1w FLASH and by 7 with T2w HASTE. With CAIPIRINHA and with HASTE, there were significantly less motion artefacts in nonsedated patients. In sedated patients, respiratory-triggered T1w imaging in general showed better image quality. However, satisfactory image quality was achieved with CAIPIRINHA in two sedated patients where respiratory triggering failed. In summary, fast scanning with CAIPIRINHA and HASTE presents a reliable high quality alternative to standard sequences in paediatric abdominal MRI. Paediatric patients, in particular, benefit greatly from fast image acquisition with less breath-hold cycles or shorter sedation.

As variáveis ambientais foram avaliadas em condições controladas com inoculação artificial e as épocas e métodos de plantio foram avaliados em condições de infecção natural em campo. Os dados de frequência de infecção analisados, como área abaixo da curva de progresso da frequência de infecção (AACPF e comprimento de lesões relacionados às variáveis ambientais, foram submetidos à análise de variância e regressão e, em seguida, plotadas as superfícies de resposta. Os dados de incidência (AACPI relacionados às épocas e métodos de plantio foram submetidos à análise de variância, utilizando-se o programa estatístico Sisvarâ/UFLA. A interação da temperatura e da duração do período de molhamento foliar influenciou a frequência de infecção e o comprimento de lesões da seca da haste. Houve aumento na frequência de infecção e no comprimento de lesões com o incremento do período de molhamento foliar e redução da temperatura. As lesões apresentaram maior tamanho na temperatura de 15ºC e 24 horas de molhamento foliar. Na ausência de molhamento foliar houve manifestação de sintomas somente a 15ºC. A 30ºC houve dependência de maior período de molhamento foliar para a manifestação de sintomas. Houve interação significativa de métodos e épocas de plantio na incidência da doença. Constatou-se menor incidência da seca da haste em transplantio de mudas comparado à semeadura direta em todas as épocas de plantio. Verificou-se aumento da incidência proporcionado pelo atraso na época de plantio nos dois métodos. Registrou-se uma relação direta entre queda de

    Full Text Available Com este trabalho, objetivou-se avaliar o desempenho de diferentes modelos matemáticos para ajuste dos dados de umidade, em função da constante dielétrica aparente do solo, e a viabilidade de uso de guias de onda de duas e três hastes, com diferentes espaçamentos. Amostras de solo deformadas foram acondicionadas em segmentos de tubos de PVC de 0,075 m de diâmetro. Construíram-se 24 guias de onda com capacitor e 24 guias de onda sem capacitor, sendo que, para cada tipo, 12 guias de onda de duas hastes e 12 de três hastes, com espaçamento entre hastes de 0,009 a 0,022 m, de impedâncias previamente determinadas, foram inseridas no solo, após a saturação em cada segmento de tubo. Dados de umidade do solo determinados por gravimetria e da constante dielétrica aparente obtidos pelo analisador Trase System, foram tomados em cada recipiente durante a secagem do solo de 0,31 a 0,13 m³ m-3. Cinco modelos matemáticos foram ajustados aos dados de umidade em função da correspondente constante dielétrica aparente do solo e o efeito dos modelos na obtenção da umidade do solo, em função da constante dielétrica aparente, foi avaliado estatisticamente. O modelo de Malicki foi o de melhor ajuste dos dados da constante dielétrica aparente, em função da umidade do solo. As guias de onda de três hastes, de diâmetro 0,003 m, comprimento 0,15 m, com espaçamentos entre hastes de 0,017 m, foram as de melhor desempenho, enquanto as guias de onda de três hastes sem capacitor indicaram melhor desempenho na determinação da umidade do solo, comparadas com as de duas hastes sem capacitor. As guias de onda de três hastes sem capacitor apresentaram melhor desempenho na determinação da umidade do solo que as de três hastes com capacitor.The objective of this study was to evaluate the performance of different mathematical models to adjust the humidity data as a function of the apparent dielectric constant of the soil and to evaluate the

    Directory of Open Access Journals (Sweden)

    Timothy Bertolet

    2017-10-01

    Full Text Available This article proposes a better source for the Son’s cry in Hebrews 5:7. It begins by surveying sources previous scholars have identified, including Jesus’ cry in Gethsemane and Golgotha, several Psalms, and the Maccabean martyr literature. It is then argued that these background sources for the language are insufficient. Instead the author of Hebrews has an entire motif from the Psalter as his informing source: the Davidic figure that cries out in trust to be delivered from a death-like experience. Firstly, the motif of the Davidic righteous suffering in the LXX Psalms is demonstrated. Secondly, Hebrews’ use of the Messianic royal figure is demonstrated and thirdly, Hebrews 5:7 as a portrait of the Christ who cries out for deliverance is demonstrated. Thus, Hebrews 5:7 sees the Son as the Davidic king who is the true representative human exercising trust in YHWH, bringing to fulfilment the theme from various Psalms.

    Full Text Available What would happen if Macbeth returned as a zombie? David Mence's "Macbeth Re-Arisen", a daring sequel of Shakespeare's Macbeth, is the answer to that question. According to award-winning author David Mence, the borders between pulp science fiction, fantasy and horror and literary fiction are more permeable than we think (Mence, 2014. In his audacious "Macbeth Re-Arisen", entirely written in blank verse, Mence blends the medieval Scotland depicted by Shakespeare with the maniacal zombies of Sam Raimi's "Evil Dead" series. This article analyses the representation of zombies as characters in relation to David Mence's "Macbeth Re-Arisen", showing some continuity between this sequel of Shakespeares "Macbeth" and zombies in cinema, popular culture, and social studies. This article also analyses characters and topoi in ÒMacbeth Re-ArisenÓ and compares them to those in Shakesperare's "Macbeth".

    Full Text Available A presença de camada de solo compactada pode significar sérios problemas ao desenvolvimento do sistema radicular das culturas em geral. A correção pode ser feita por métodos biológicos ou mecânicos. Uma das formas de diagnóstico da sua presença é com o uso de penetrômetros que exigem tempo considerável para a obtenção de dados. Com o advento dos recursos de espacialização das informações na forma de mapas, a necessidade de amostragem passou a ser ainda maior. Este trabalho reporta a busca de uma solução alternativa ao uso do penetrômetro. Envolve a geração de mapas de resistência mecânica do solo ao deslocamento de uma haste em três profundidades, baseado em três hastes instrumentadas, um receptor de GPS e um sistema de aquisição de dados. O sistema é acoplado a uma barra porta-ferramenta montada no engate de três pontos do trator. A configuração mostrou ser mecanicamente bastante simples e confiável. Dados de um teste inicial em campo demonstraram que o sistema pode produzir mapas que denotam a variabilidade espacial da referida resistência nas áreas amostradas, com alta resolução, densidade de amostragem elevada e com capacidade operacional ainda mais elevada se comparada com levantamentos feitos com métodos convencionais.The presence of soil compaction may be considered a serious problem for the development of crop root systems. It can be alleviated by biological or mechanical methods (such as tillage. One of the most popular diagnostic methods is based on standardized cone penetrometer measurements, which requires a considerable amount of time to obtain the data. With the advent of site-specific field management, high-density measurements have become a necessity. This work reports on an alternative approach to use a cone penetromenter. It involves the generation of maps of soil mechanical resistance at three depths using three instrumented blades, a GPS receiver and a data logger. The system is attached

    Whether prey retains antipredator behavior after a long period of predator relaxation is an important question in predator-prey evolution. Père David's deer have been raised in enclosures for more than 1200 years and this isolation provides an opportunity to study whether Père David's deer still respond to the cues of their ancestral predators or to novel predators. We played back the sounds of crows (familiar sound) and domestic dogs (familiar non-predators), of tigers and wolves (ancestral predators), and of lions (potential naïve predator) to Père David's deer in paddocks, and blank sounds to the control group, and videoed the behavior of the deer during the experiment. We also showed life-size photo models of dog, leopard, bear, tiger, wolf, and lion to the deer and video taped their responses after seeing these models. Père David's deer stared at and approached the hidden loudspeaker when they heard the roars of tiger or lion. The deer listened to tiger roars longer, approached to tiger roars more and spent more time staring at the tiger model. The stags were also found to forage less in the trials of tiger roars than that of other sound playbacks. Additionally, it took longer for the deer to restore their normal behavior after they heard tiger roars, which was longer than that after the trial of other sound playbacks. Moreover, the deer were only found to walk away after hearing the sounds of tiger and wolf. Therefore, the tiger was probably the main predator for Père David's deer in ancient time. Our study implies that Père David's deer still retain the memories of the acoustic and visual cues of their ancestral predators in spite of the long term isolation from natural habitat.

    Pablo Picasso (1881-1973) is quoted as saying, "The meaning of life is to find your gift. The purpose of life is to give it away." With these few words Picasso captures the essence of David Drum's existence. From his birth in Moncton, NB, through his formal education in Toronto, ON, to his so-called "retirement" in Crystal Beach, ON, this paper spans 72 years, unveiling the broad range of opportunities for growth David Drum has encountered in his life's journey and documenting his acceptance of the obligations for proud philanthropy that accompany them. Dr. Drum's many accomplishments, gifts, and contributions to the profession and world of art are discussed.

  20. David I reimplantation procedure for aortic root replacement in Marfan patients: medium-term outcome.

    Technical variations of the David reimplantation valve-sparing aortic root replacement (V-SARR) procedure have been proposed to be advantageous in patients with connective tissue disease, such as the Marfan syndrome (MFS). We report results of a Marfan cohort treated exclusively with the non-modified David I procedure. Forty-eight Marfan patients (25 males, mean age 33 ± 12 years, range 15-62 years) underwent the original variant of the David V-SARR (David I) between 1997 and 2013. Forty-two operations (88%) were performed as elective procedures for aortic root aneurysms and six for acute dissections (12%). Seventeen had aortic regurgitation (AR) grades ≥2+ preoperatively, and 3 had AR >2+. No patients with severe AR (4+) were selected for V-SARR. Three full or hemi-arch replacements were performed. Patients who were operated on using a variation of the David I or David II procedure were excluded. Mean prosthesis size was 28 ± 3 mm (18-30 mm). Mean clinical and echocardiographic follow-up (98% complete) was 3.8 ± 3.7 years with a cumulative follow-up of 178 patient-years. The early mortality rate was 2% (one hospital death). The survival rate was 98% (95% confidence 84-99%) at 4 years and 90% (57-98%) at 8 years with 5 patients at risk at 10 years. The rate of freedom from root or valve reoperation was 97% (79-99%) and 97% (79-99%) at 4 and 8 years, respectively. Only one patient required mechanical aortic valve replacement for progression of AR. Despite potential theoretical drawbacks of the David I V-SARR technique without neo-sinuses or a neo-sinotubular junction, it results in a favourable mid-term outcome in Marfan patients and compares well with reported results of different modifications of David V-SARR. © The Author 2014.

    Full Text Available Taking Anne Friedberg's notion of the post-perspectival as the point of departure for her analysis of David Lynch's digitally shot and edited Inland Empire from 2006, Anne Jerslev argues that the film deconstructs continuous time and coherent space by constructing multiple planes of representation, multiple layerings of screens and, hence, multiple and fractured modes of perception. The article further suggests that the film's enigmatic structure might best be understood with reference to a new media genre like the website with its hyperlink structure. Finally, the article discusses how a sense of ubiquitous surveillance coalesces with the screen logic.Author Biography Anne Jerslev (PhD is Professor of Film and Media Studies at the Department of Media, Cognition and Communication, University of Copenhagen.

  13. Benefits of a new Metropolis-Hasting based algorithm, in non-linear regression for estimation of ex vivo antimalarial sensitivity in patients infected with two strains.

    Science.gov (United States)

    Bauer, Rebecca; Mentré, France; Kaddouri, Halima; Le Bras, Jacques; Le Nagard, Hervé

    2014-12-01

    Malaria is one of the world׳s most widespread parasitic diseases. The parasitic protozoans of the genus Plasmodium have developed resistance to several antimalarial drugs. Some patients are therefore infected by two or more strains with different levels of antimalarial drug sensitivity. We previously developed a model to estimate the drug concentration (IC50) that inhibits 50% of the growth of the parasite isolated from a patient infected with one strain. We propose here a new Two-Slopes model for patients infected by two strains. This model involves four parameters: the proportion of each strain and their IC50, and the sigmoidicity parameter. To estimate the parameters of this model, we have developed a new algorithm called PGBO (Population Genetics-Based Optimizer). It is based on the Metropolis-Hasting algorithm and is implemented in the statistical software R. We performed a simulation study and defined three evaluation criteria to evaluate its properties and compare it with three other algorithms (Gauss-Newton, Levenberg-Marquardt, and a simulated annealing). We also evaluated it using in vitro data and three ex vivo datasets from the French Malaria Reference Center. Our evaluation criteria in the simulation show that PGBO gives good estimates of the parameters even if the concentration design is poor. Moreover, our algorithm is less sensitive than Gauss-Newton algorithms to initial values. Although parameter estimation is good, interpretation of the results can be difficult if the proportion of the second strain is close to 0 or 1. For these reasons, this approach cannot yet be implemented routinely. Copyright © 2014 Elsevier Ltd. All rights reserved.

    2017-03-01

    Full Text Available This article analyses the influence of David Bowie’s work in JoJo’s Bizarre Adventure, a manga known for its wealth of references to western popular culture. It is argued that David Bowie’s cultural reception can be attested via the presence of three narrative themes featuring in this manga series. The first theme is the exploration of diverse genres and an innovative, genre-defying attitude. The second theme is the use of avant-garde, flamboyant and gender-ambiguous aesthetics for its fictional characters. The third theme is a self-reflexive approach to the creation of fictional characters, intended as an awareness of the temporary, transient nature of their role as reluctant heroes in their own stories.

    Forstner, C.

    2005-07-01

    This paper touches on some general questions of theory construction in physics, by presenting a biographical case study of David Bohm through the perspective of Fleckian thought-collectives and their thought-style. In the 1920s a small elite of physicists established the Copenhagen Interpretation of quantum mechanics as a new thought-style in the thought-collective of the physicists. In the following decade the Copenhagen Interpretation was transferred from Europe to the USA, from one thought-collective into another, and was integrated into a specific American thought-style. David Bohm was initiated in this mode of thought during his undergraduate studies at the Pennsylvania State College and his graduate studies at Caltech and the University of California at Berkeley.

    Full Text Available Quando o artigo Uma proposta de interpretação da teoria quântica em termos de variáveis" escondidas", de autoria de David Bohm, foi publicado, ele estava no Brasil, na Universidade de São Paulo. Atingido pelo McCarthysm, Bohm perdeu sua posição na Universidade de Princeton e, por isto, veio para o Brasil, onde permaneceu de outubro de 1951 a janeiro de 1955. Analisamos sua atividade neste período, incluindo sua interpretação da teoria quântica, e a recepção desta pela comunidade científica. Destacamos que, apesar das condições adversas, a sociedade brasileira foi capaz de acolher o cidadão e cientista perseguido politicamente, e assegurar a continuidade de seu trabalho científico. A ciência brasileira foi bastante beneficiada pelo ensino, pela pesquisa e pela permanente preocupação com os fundamentos da física, características do trabalho de David Bohm.When the paper A Suggested interpretation of the quantum theory in terms of "hidden" variables, by David Bohm, was published he has been in Brazil at University of São Paulo.

    Modern 3D scanning technologies allow to reconstruct 3D digital representations of Cultural Heritage artifacts in a semi-automatic way, characterized by very high accuracy and wealth of details. The availability of an accurate digital representation opens several possibilities of utilization to experts (restorers, archivists, museum curators), or to ordinary people (students, museum visitors). 3D scanned data are commonly used for the production of animations, interactive visualizations, or virtual reality applications. A much more exciting opportunity is to use these data in the restoration of Cultural Heritage artworks. The integration between 3D graphic and restoration represents an open research field where many new supporting tools are required; the David restoration project has given several starting points and guidelines to the definition and development of innovative solutions. Digital 3D models can be used in two different but not subsidiary modes: as an instrument for the execution of specific investigations and as a supporting media for the archival and integration of all the restoration-related information, gathered with the different studies and analysis performed on the artwork. In this paper we present some recent work done in the framework of the Michelangelo's David restoration project. A 3D model of the David was reconstructed by the Digital Michelangelo Project, using laser-based 3D scanning technology. We have developed some tools to make those data accessible and useful in the restoration. Preliminary results are reported here together with some directions for further research.

    Full Text Available RESUMEN La ocupación del Centro Financiero Cofinanzas, más conocido como Torre David, ha sido tan alabada como criticada. Quizá porque más allá de la ilegalidad, la apropiación del símbolo de una época de desigualdad puso en jaque ciertos pilares fundamentales en la producción de lo urbano. De un lado las políticas económicas y sociales, que salvo excepciones no han hecho sino impulsar la desigualdad, la pobreza y la exclusión social. Del otro la academia, la profesión y las políticas urbanas heredadas del planeamiento urbano moderno, las cuales han probado fomentar la segregación espacial, anular la diversidad y destruir el ámbito público. Pero este complejo de 45 plantas y 110.000 m2 era una entidad híbrida, vertical y vacante en el mismo corazón de la ciudad cuya obsolescencia como objeto físico, político y económico fue objetivo de una presión social ya incontenible. Tanto por su escala y diversidad como por su estado inacabado, sus moradores descubrieron una condición urbana excepcional para reconstruir su nueva identidad como ciudadanos. Un conjunto de cinco sistemas abiertos con los que transformar aquella obsolescencia en una parte de la ciudad alternativa; una infraestructura social. Como ya hicieran otros maestros en el pasado el proceso de Torre David replantea, ahora de forma anónima, bajo qué condiciones los sistemas abiertos permiten elaborar estrategias de regeneración urbana y social, sistemas con los que diluir las complicadas fronteras internas creadas en la ciudad contemporánea. SUMMARY The occupation of the Cofinanzas Financial centre, better known as the Tower of David, has been praised as well as criticised. Perhaps because beyond the illegality, the appropriation of a symbol of a time of inequality threatened certain fundamental pillars on the production of urban.

  13. DAVID Knowledgebase: a gene-centered database integrating heterogeneous gene annotation resources to facilitate high-throughput gene functional analysis

    Directory of Open Access Journals (Sweden)

    Baseler Michael W

    2007-11-01

    Full Text Available Abstract Background Due to the complex and distributed nature of biological research, our current biological knowledge is spread over many redundant annotation databases maintained by many independent groups. Analysts usually need to visit many of these bioinformatics databases in order to integrate comprehensive annotation information for their genes, which becomes one of the bottlenecks, particularly for the analytic task associated with a large gene list. Thus, a highly centralized and ready-to-use gene-annotation knowledgebase is in demand for high throughput gene functional analysis. Description The DAVID Knowledgebase is built around the DAVID Gene Concept, a single-linkage method to agglomerate tens of millions of gene/protein identifiers from a variety of public genomic resources into DAVID gene clusters. The grouping of such identifiers improves the cross-reference capability, particularly across NCBI and UniProt systems, enabling more than 40 publicly available functional annotation sources to be comprehensively integrated and centralized by the DAVID gene clusters. The simple, pair-wise, text format files which make up the DAVID Knowledgebase are freely downloadable for various data analysis uses. In addition, a well organized web interface allows users to query different types of heterogeneous annotations in a high-throughput manner. Conclusion The DAVID Knowledgebase is designed to facilitate high throughput gene functional analysis. For a given gene list, it not only provides the quick accessibility to a wide range of heterogeneous annotation data in a centralized location, but also enriches the level of biological information for an individual gene. Moreover, the entire DAVID Knowledgebase is freely downloadable or searchable at http://david.abcc.ncifcrf.gov/knowledgebase/.

  14. Getting Past the ‘Post-’: History and Time in the Fiction of David Mitchell

    Full Text Available This paper examines David Mitchell’s Cloud Atlas (2004 and The Thousand Autumns of Jacob de Zoet (2010, with a particular focus on history and narrative time. It seeks to offer an alternative perspective on the multiple and intertwined fictional narratives of Mitchell’s oeuvre as these evidence a move past the "post-" of postmodernism. Keywords: David Mitchell, time, narrative, historiography, experimental fiction, post-postmodernismPostmodernism has cast an extended influence over much literary criticism in the last fifty years. However, with the end of the noughties now in reach of critical hindsight, and with the shock of September 11, 2001 beginning to subside, significant attention is turning once again toward the new literary vanguard. Efforts to discuss post-postmodernism, critical realism, new materialism, and new-millennial writing are certainly on a par with artistic and literary efforts to move beyond postmodernist playfulness and relativism. Within this broader framework, scholars have debated the fiction of David Mitchell, often straining to include his literary experimentalism with categories of the postmodern. However, resisting these efforts in the two novels chosen for analysis here, Mitchell’s writing appears to return from the abstraction and playfulness of postmodern poetics to settle as an engaged writing practice concerned with the materiality of time and of history. With time and history as its conceptual anchors, Mitchell’s more literary practice in the novels discussed here confronts developed postmodernist approaches to the past through an insistence upon a sense of time that abjures postmodern paradigms of uncertainty and relativity. This paper will examine time and narrative in relation to selected recent works by Mitchell in order to allow an alternative perspective on the workings of the multiple and intertwined fictional narratives across his novels; a perspective which can enlarge our understanding of how

    Aortic valve-sparing David procedure has gained broad acceptance. However, few long-term results have been published. We present our results. More than 450 David procedures have been performed in our institution so far. Of these, 126 patients were operated between July 1993 and December 2000. Median age was 57 (8-83) years and 46 (36.5%) were female. As many as 26 (20.6%) had Marfan syndrome, 21 (16.7%) had acute aortic dissection type A (AADA) and 67 (53.2%) had additional procedures. There were six (4.8%) deaths in 30 post-operative period (POD), four of whom had AADA. In the follow-up, there were 32 (25.4%) late deaths, 11 (34.4%) of these were caused by cardiac or underlying disease or op-related. As many as 15 (11.9%) patients were re-operated; six (40%) were Marfan patients and two (13.3%) had early endocarditis. Follow-up echocardiography of 76 (60.3%) event-free patients showed valve insufficiency (AI)≤AI I° in 68 (89.5%) and grade II in 7 (9.2%) patients. Leaflet degeneration due to proposed leaflet contact with the straight Dacron graft was not observed. A total of 36 (47.4%) patients were in New York Heart Association (NYHA) class I, 33 (43.4%) in NYHA II, and five (6.6%) were in class III. During the entire follow-up of 790 patient-years, there was no stroke or major bleeding. Survival at 1, 5 and 10 years was 93%, 85% and 70%, respectively. Freedom from valve replacement at 1, 5 and 10 years was 96%, 91% and 87%, respectively. Regardless of the underlying pathology, valve-sparing David I procedure has acceptable long-term results. Valve-related complications such as stroke or major bleeding is exceedingly low.

At the same time, we challenge the author to incorporate more of a process perspective into the theory. This would include greater exploration of how individuals enter and exit this hypothesized Circle of Discontent, how these mechanisms lead to obesity rather than other internalizing or externalizing disorders, and how the interactions among key variables differ for males and females and developmental stages.

    2012-05-01

    Writing a study of psychologist David Boder's 1946 displaced persons (DP) interview project gave me a chance to further document the substantial early response to the Holocaust. This was clearly one important piece of my study, and one that was eminently straightforward. Yet much of the research on Boder's project at the point in time that I carried it out was elliptical, partly because the primary interview materials were coming to light at an astonishing pace, partly because the archive collections were virtually untapped, and partly because of the misconception of Boder and his interview project itself.

    Full Text Available OBJECTIVE: To compare efficiency of external fixator in modular form with unilateral and uniplanar intramedullary locked seeking definitive treatment of fractures of the tibia diaphysis. METHODS: Orthopedic surgical treatments were compared to 50 patients with definite diafisária fracture of the tibia, through the use of the external fixator, modular and intramedullary locked. The fractures were treated at emergency hospital school of Orthopedics and Traumatology service in the period from January 2007 to January 2011, with a variation of 15 to 48 weeks. RESULTS: this study has proven functional results and excellent consolidation when locked intramedullary rods were used and the versatility and speed of application of external fixator reaching the necessary stabilization of bony fragments. Consolidation of fractures was obtained in 95 cases when using the intramedullary locked and 90 cases undergoing external fixation. CONCLUSIONS: the definitive treatment of tibial diaphysis fractures by external fixator modular presented themselves as valid alternative treatment in patients who could not be submitted for early conversion to internal osteosynthesis or when the intramedullary nails are not available to the surgeon.

    Full Text Available Inúmeros problemas relativos à mecanização dizem respeito aos esforços demandados pelas máquinas e implementos agrícolas. A medição dos esforços em implementos de hastes é geralmente feita por instrumentos complexos e de difícil construção, como os anéis octogonais. Sendo assim, o objetivo deste artigo é apresentar o desenvolvimento de um dispositivo de mediç��o de esforços horizontais e verticais em hastes sulcadoras de semeadoras-adubadoras de plantio direto, utilizando transdutores de força extensiométricos do tipo viga em balanço, comercialmente disponíveis. Para tanto, projetou-se um dispositivo tipo pórtico, composto de dois transdutores para medição de esforços horizontais e um transdutor para medição do esforço vertical. Os três transdutores foram montados de modo a restringir qualquer movimento da haste durante a interação com o solo. O protótipo construído foi submetido a ensaios estáticos em bancada de laboratório. Em um dos ensaios, aplicou-se carga horizontal na haste; no outro, aplicou-se carga vertical e no terceiro, a carga foi aplicada com inclinação de 15º em relação à horizontal, para simular as condições de operação da haste no campo. O dispositivo mostrou-se robusto e, durante os testes de bancada, foi capaz de medir esforços horizontais de até 5.300 N, e esforços verticais de até 2.000 N, de forma linear e com grande coeficiente de correlação com as cargas aplicadas.Many problems related to the mechanization involve the draft demanded by machinery and agricultural implements. The measurement of forces in shank implements is generally made by complex and difficult building instruments, as the octagonal ring. Therefore, the aim of this paper is to present the development of a device for measuring the horizontal and vertical forces in shanks of no-till planters by employing off the shelf shear beam force transducers. For this purpose a square shaped frame was designed

    Over the last forty years, David Vogan has left an indelible imprint on the representation theory of reductive groups.  His groundbreaking ideas have lead to deep advances in the theory of real and p-adic groups, and have forged lasting connections with other subjects, including number theory, automorphic forms, algebraic geometry, and combinatorics. Representations of Reductive Groups is an outgrowth of the conference of the same name, dedicated to David Vogan on his 60th birthday, which took place at MIT on May 19-23, 2014.  This volume highlights the depth and breadth of Vogan's influence over the subjects mentioned above, and point to many exciting new directions that remain to be explored.  Notably, the first article by McGovern and Trapa offers an overview of Vogan's body of work, placing his ideas in a historical context.

    2010-10-01

    Full Text Available This essay analyzes two works, My Brother by Jamaica Kincaid, and "Saturn Street" by David Leavitt, investigating the construction of homosexuality as a process accomplished by resorting to illness (AIDS and death. In both works, indeed, the slow and dramatic course of AIDS amounts to the progressive unveiling of homosexuality as a social threat or a cause of anxiety and repulsion. The two works are set in different contexts: whereas Jamaica Kincaid refers to the problematic situation of homosexuality in the Caribbean, David Leavitt explores the social and cultural scenario of the 1990s Los Angeles, in the wake of a by now ended utopian confidence in science and technology.  This comparative approach helps us understand the political dynamics through which, in different and, to some extents, opposite realities, the social stigma of AIDS worked as a means to construct homosexual identity and set it apart from the sanitized spectrum of normal and sanctioned sexual behaviors. The point I want to make in this essay is that the corpse is used as an effective metaphor for a dehumanized depiction of male homosexual and ill subjects.

    Network structures based on Star-of-David catenanes with multiple superior functionalities have been so far elusive, although numerous topologically interesting networks are synthesized. Here, a metal-organic framework featuring fused Star-of-David catenanes is reported. Two triangular metallacycles with opposite handedness are triply intertwined forming a Star-of-David catenane. Each catenane fuses with its six neighbors to generate a porous twofold intercatenated gyroid framework. The compound possesses exceptional stability and exhibits multiple functionalities including highly selective CO 2 capture, high proton conductivity, and coexistence of slow magnetic relaxation and long-range ordering. © 2017 WILEY-VCH Verlag GmbH & Co.

    sufficiently close to any corrugated—and/or any smooth—surface and thus enforce a strong vdW-type adhesion; it exploits what is then essentially a contact force (dominated by the attraction exerted in the near-surface regions) to defy the pull of gravity on its own bulk. This Journal of Physics: Condensed Matter special issue is dedicated to the memory of David C Langreth. David is a dearly missed friend and mentor who inspired many of us. He was an outstanding condensed matter theorist and a scholar who greatly influenced us through his many-particle-physics based insights into density functional theory (DFT), surface science and related areas. His seminal works range from conserving formulations of interacting nonequilibrium transport [1] and formal-scattering theory [2] to an explicit formulation [3] of the exact DFT exchange-correlation energy in the adiabatic connection formula (ACF), the latter also being derived independently by Gunnarsson and Lundqvist [4]. David's portfolio also includes an analysis [5] that helped catalyze and guide the development of DFT from the local-density approximation (LDA) to the formulations of generalized gradient approximations (GGAs). Another salient contribution of David's is in the area of vdW interactions in materials. He was a key architect of the vdW density functional (vdW-DF) method [6, 7]. This method was developed in a long-standing Rutgers-Chalmers collaboration between David's group and that of Bengt I Lundqvist, later extending to a wider group of researchers on both sides of the Atlantic. Plasmons are collective excitations that depend on electron-density variation. The plasmon response can be seen as defining the nature of the LDA [4] and their description can thus also be seen as contributing to the success of GGA. The vdW-DF method is a regular constraint-based density functional (for ground-state DFT) which is derived within the ACF framework and which emphasizes the electrodynamical nature of the coupling between

After a 15-minutes-immersion in distilled water and NAA and GA3 solutions at concentrations of 10, 100, 500 and 1000 µmol L-1, and 2,4-D solutions at concentrations of 1, 10, 50 and 100 µmol L-1, the shoots were stored in polyethylene bags at 5 ± 1ºC for 74 days. Percentage of leaf petiole abscission, fresh and dry matter losses, bud viability, and growth flush were evaluated. NAA and 2,4-D had the highest efficiency for petiole abscission inhibition, reaching almost 99% of success. The packaging system and shoot storage under low temperature efficiently reduced fresh and dry matter losses. Bud viability of 'Baianinha', 'Valencia' and 'Murcott' shoots was not reduced by storage, maintaining above 95% of grafting success. NAA, GA3 and 2,4-D treatments had no influence on sprout growth.O armazenamento refrigerado possibilita a conservação de hastes porta-borbulhas de citros por vários meses, embora ocorra perda gradual da viabilidade das borbulhas e abscisão dos pecíolos foliares.

O trabalho avaliou os efeitos de quatro níveis de nitrogênio e dois níveis de boro e da interação entre eles na incidência de hastes ocas e na produção de brócolis. As doses de N (100, 150, 200 e 250 kg ha-1 foram divididas em quatro aplicações iguais aos 15, 30, 45 e 60 dias após o transplante. O boro (0, 4 e 8 kg ha-1 foi aplicado metade no plantio e a outra metade em cobertura aos 45 dias após o transplante. A massa média das inflorescências e a produção total foram diminuídas com a aplicação de B em função do crescimento mais lento das plantas provocado pela toxicidade desse elemento. Contudo, nas áreas não adubadas com B, a porcentagem de plantas com hastes ocas foi, em média, de 44,14%, sendo que a incidência dessa anomalia sofreu drástica redução com a aplicação de B, onde a maior dose (8 kg ha-1 resultou em apenas 4,52% de inflorescências afetadas. Doses de N superiores a 215,4 kg ha-1 aumentaram o número de plantas com hastes ocas somente nas áreas que não receberam B.The incidence of hollow stem in broccoli (Brassica oleracea L. var. italica Plenck depends on several factors that affect the absorption and transport of boron, which is the element responsible for the appearance of this physiological disorder.

    2013-01-01

    During the last half of the twentieth century, the concept of system was arguably the most important concept in the theoretical repertoire of the discipline of American political science. Although systems analysis was broadly employed in the behavioral sciences, David Easton's work was particularly influential in the study of politics. This is in part because he attempted to develop a distinct account of the political system that was not theoretically subservient either to general systems theory or to conceptions of the social system such as that advanced by Talcott Parsons. Although a great deal of attention has been devoted to Easton's theory, the origins and evolution of the system concept in his work have not been carefully reconstructed and analyzed. © 2013 Wiley Periodicals, Inc.

    James Wright

    2008-05-01

    Full Text Available In his most recent contribution to an important and well-framed series of papers on auditory grouping and the perception of polyphonic music, David Huron seeks further evidence for his working hypothesis that J.S. Bach controls the employment of perfect consonances by desynchronizing their onsets, thereby inhibiting the perceptual fusion of polyphonic voices. However the more novel contribution of the present study would seem to be its demonstration that Bach also regulates the employment of dissonant tones by consistently desynchronizing their onsets. This finding provides the first concrete evidence for Wright and Bregman’s otherwise untested hypothesis that the control and salience of dissonance in polyphonic music are closely related to principles of auditory stream segregation (Wright, 1986; Wright & Bregman, 1987.

    Full Text Available The American Dream is a recurrent theme in American literature. In this response, this paper is an attempt to expose the destructive effects of the dream on the human spirit. It is also shown, through the analysis of David Mamet’s glengarry Glen Ross, that despite the promise of the dream it contains many contradictions. Beneath the seeming simple surface of the play lies a deep current of meanings that reflect the calamities of modern American life, and in a broader sense, the modern world.

    L. David Marquet, a decorated Navy Captain, transformed an underperforming submarine crew by empowering his subordinates to be leaders and reach their full potential. He called this intent-based leadership (IBL). What would happen if Marquet's model were implemented in Graduate Medical Education (GME)?In this letter to the editor, we summarize the potential of the IBL model in graduate medical education as opposed to the traditional leader-follower method. IBL harnesses human productivity toward the shared goals of GME, which are patient care and trainee learning. This shift in mindset could lead both teachers and trainees to focus more on the real reason that we undertake GME and change behaviors for the better. We suggest that IBL can and should be adopted in GME and propose that both patients and providers will benefit from this action.

    This remedial investigation (RI)/feasibility study (FS) supports the selection of remedial actions for the David Witherspoon, Inc. 901 Maryville Pike Site in Knoxville, Tennessee. Operations at the site, used as a recycling center, have resulted in past, present, and potential future releases of hazardous substances in to the environment. This Site is a Tennessee Superfund site. A phased approach was planned to (1) gather existing data from previous investigations managed by the Tenn. Dept. of Environment and Conservation; (2) perform a preliminary RI, including risk assessments, and an FS with existing data to identify areas where remedial action may be necessary; (3) gather additional field data to adequately define the nature and extent of risk-based contaminants that present identifiable threats to human and/or ecological receptors; and (4) develop remedial action alternatives to reduce risks to acceptable levels.

  14. Modeling Instruction of David Hestenes: a proposal of thematic modeling cycle and discussion of scientific literacy

    2016-07-01

    Full Text Available The pedagogical work with mathematical modeling assumes investigate situations of reality. However, mental models formed from the contact with the experiential world are generally incompatible with the conceptual models. So David Hestenes supports the view that one of the biggest challenges of teaching and learning in science and mathematics is to coordinate conceptual models with mental models, which led to the elaboration of a didactic in mathematical modeling: Modeling Instruction. Our goal is to present a proposal for thematic modeling cycle drawn up in hestenesianos assumptions and discuss possibilities for scientific literacy. The main question was to know how to emerge indicators for scientific literacy for the proposed cycle. This is a bibliographic research in order to identify the available literature contributions on the subject and raise the possibility and challenges for the brazilian teaching science and mathematics. Preliminary results indicate that the proposed modeling cycle can develop indicators for scientific literacy of different natures.

  15. David Hartley's views on Madness: With an introduction by GE Berrios.

    The psychiatric aspects of David Hartley's writings have received less attention than the rest of his work. This Classic Text deals with Section VI of his Observations on Man …, namely, the 'Imperfections of the rational Faculty'. Hartley defines madness as an imperfection of reason that can be temporary or enduring. He makes use of his model of mental functioning to differentiate between eight clinical categories of madness, each representing a different pattern of vibrations of the nerves. Hartley developed this model based on Newton's theory of vibrations and, to explain the complexity of mental acts and entities, he combined it with his own version of the mechanism of Association of Ideas borrowed from John Locke. Much work needs to be done to identify the provenance of Hartley's nosology and nosography. © The Author(s) 2015.

    An important area of applied mathematics is the Chemical reaction network theory. The behavior of real world problems can be modeled by using this theory. Due to applications in theoretical chemistry and biochemistry, it has attracted researchers since its foundation. It also attracts pure mathematicians because it involves interesting mathematical structures. In this report, we compute newly defined topological indices, namely, Arithmetic-Geometric index (AG1 index), SK index, SK1 index, and SK2 index of the dominating David derived networks [type="bibr" rid="j_phys-2017-0126_ref_001">1, type="bibr" rid="j_phys-2017-0126_ref_002">2, type="bibr" rid="j_phys-2017-0126_ref_003">3, type="bibr" rid="j_phys-2017-0126_ref_004">4, type="bibr" rid="j_phys-2017-0126_ref_005">5].

    2011-11-01

    Full Text Available While historical materialism and evolutionism provide similar explanations and ideas regarding the cause of long-term social change, the two theories are rarely used in conjunction with one another. In Deep History,the author David Laibman addresses some of the standard questions of evolutionary social theory and attempts to bridge the two concepts, by showing that historical and materialist explanations are present in both Marxian and evolutionary interpretations of history. His goal: develop a Marxist theory of history from an evolutionist perspective, and surmount the traditional confines of historical materialism, so as to embrace evolutionary conceptions in explaining social change. However, the unbalanced research methodology limits the reach and depth of Laibman’s contribution. The two main shortcomings of his work are discussed in the following sections: The Audience Problem and The Evolutionary Problem.

  18. Fairness and Respect in Obesity Prevention Policies: A Response to David Buchanan

    Directory of Open Access Journals (Sweden)

    Katherine King

    2014-01-01

    Full Text Available In his response to our article (1,2, David Buchanan introduces some useful and important distinctions in the concepts of equality and autonomy. He highlights, for example, the distinction between inequality and inequity, which captures the insight that not all differences between people are unjust. Unjust inequalities are a subset of differences between people, and theories of justice can be defined by how they determine which of these differences are unjust. In addition, he points out that autonomy is not simply a matter of negative liberty, but also about a positive capacity to act. This understanding of autonomy is consistent with the account we offered in the paper, which underlines the importance of both the capacity to understand available options, and the capacity to act on the choices that one makes.

  19. Hacking the aesthetic: David Haines and Joyce Hinterding's new ecologies of signal

    Directory of Open Access Journals (Sweden)

    Andrew Murphie

    2012-06-01

    Full Text Available Award winning Australian electronic artists David Haines and Joyce Hinterding's installation work is discussed as “signal-work.” Their work reconfigures signal within original assemblages involving subtle audio, high resolution video (both recorded and animated, kilometers of coiled copper wire, antennae or home-built electronics, electrostatic disturbances, the like of very low frequency radiation from the Milky Way, and cross-signal processing. The article develops a context for thinking about the work in terms of Whitehead's process philosophy, as this is relevant to media theory, as well as concepts of plural ecology and ongoing differentiation drawn from Bateson and Guattari. Signal processing is seen as key to all this. The article argues that in Hinterding and Haines’ signal-work new sensations are produced, outside of the normal “syntax” of some models of aesthetic experience. This challenges some aspects of thinking about both aesthetics and political ecology.

  1. M-Polynomials and Topological Indices of Dominating David Derived Networks

    Directory of Open Access Journals (Sweden)

    Kang Shin Min

    2018-03-01

    Full Text Available There is a strong relationship between the chemical characteristics of chemical compounds and their molecular structures. Topological indices are numerical values associated with the chemical molecular graphs that help to understand the physical features, chemical reactivity, and biological activity of chemical compound. Thus, the study of the topological indices is important. M-polynomial helps to recover many degree-based topological indices for example Zagreb indices, Randic index, symmetric division idex, inverse sum index etc. In this article we compute M-polynomials of dominating David derived networks of the first type, second type and third type of dimension n and find some topological properties by using these M-polynomials. The results are plotted using Maple to see the dependence of topological indices on the involved parameters.

  2. David Mitrany and South-East Europe: The Balkan Key to World Peace

    Directory of Open Access Journals (Sweden)

    Lucian M. Ashworth

    2006-01-01

    Full Text Available Today David Mitrany is best known for his work on international functionalism, which influenced the development of European integration and the organisation of United Nations specialised agencies. What is often ignored in the West is his work on South-East Europe. During the inter-war period Mitrany studied both the operation of war government and the subsequent peasant revolution in the Balkans. War government demonstrated that political organisation could bridge the gap between social action and private property, while the peasant social revolution showed that the abstract economics associated with both capitalist and Marxist economics was not applicable outside of urban industrial production. It was through his studies of South-East Europe that Mitrany drew many of the lessons and concepts that were to form the foundations of his international theory.

    profile as a whole. We present results from an Observing System Simulation Experiment (OSSE) designed to investigate the impact of management and climate change on peatland carbon fluxes, as well as how observations from satellites may be able to constrain modeled carbon fluxes. We use an adapted version of the Carnegie-Ames-Stanford Approach (CASA) model (Potter et al., 1993) that includes a representation of methane dynamics (Potter, 1997). The model formulation is further modified to allow for assimilation of satellite observations of surface soil moisture and land surface temperature. The observations are used to update model estimates using a Metropolis Hastings Markov Chain Monte Carlo (MCMC) approach. We examine the effect of temporal frequency and precision of satellite observations with a view to establishing how, and at what level, such observations would make a significant improvement in model uncertainty. We compare this with the system characteristics of existing and future satellites. We believe this is the first attempt to assimilate surface soil moisture and land surface temperature into an ecosystem model that includes a full representation of CH4 flux. Bubier, J., and T.

    The continent of Antarctica has approximately the same surface area as the continental United States, though we know significantly less about its underlying geology and seismic activity. In recent years, improvements in seismic instrumentation, battery technology, and field deployment practices have allowed for continuous broadband stations throughout the dark Antarctic winter. We utilize broadband seismic data from a recent experiment (TAMNNET), which was originally proposed as a structural seismology experiment, for seismic event detection. Our target is to address fundamental questions about regional-scale crustal and environmental seismicity in the study region that comprises the Transantarctic Mountain area of Victoria and Oates Land. We identify most seismicity emanating from David Glacier, upstream of the Drygalski Ice Tongue, which has been documented by several other studies. In order to improve the catalog completeness for the David Glacier area, we utilize a matched-filter technique to identify potential missing earthquakes that may not have been originally detected. This technique utilizes existing cataloged waveforms as templates to scan through continuous data and to identify repeating or nearby earthquakes. With a more robust catalog, we evaluate relative changes in icequake positions, recurrence intervals, and other first-order information. In addition, we attempt to further refine locations of other regional seismicity using a variety of methods including body and surface wave polarization, beamforming, surface wave dispersion, and other seismological methods. This project highlights the usefulness of archiving raw datasets (i.e., passive seismic continuous data), so that researchers may apply new algorithms or techniques to test hypotheses not originally or specifically targeted by the original experimental design.

    Full Text Available David Roberts' views of Córdoba were carried out in 1833 and later redrafted as lithographs, engravings, and oils. These artworks enjoyed great commercial success and international diffusion due to their thematic and undoubted artistic value. The authors analyze their documentary value as a graphic record -prior to the advent of photography- of the urban landscape and architecture of Cordoba, a city now denominated a World Heritage Site. These images are studied here for the first time as a group, since they are either virtually untraceable or dispersed in museums throughout the world. In addition, these views have been contextualized with information concerning the artist and his Spanish journey, including a letter that he wrote from Córdoba. The documentary reliability of every image is also assessed, while the significant transformations of the places represented are indicated.Las vistas realizadas en Córdoba por David Roberts en 1833, reelaboradas como litografías, grabados y óleos, han gozado de gran éxito comercial y difusión internacional por su temática e indudable interés artístico. Esta investigación profundiza en su valor documental como registros gráficos previos a la aparición de la fotografía, del paisaje y la arquitectura de una ciudad hoy considerada Patrimonio de la Humanidad. Las imágenes presentadas se analizan por primera vez como conjunto, pues algunas son de difícil localización o están dispersas en museos de todo el mundo, y se contextualizan con datos sobre el pintor y su viaje por España, considerando una carta que éste escribió desde Córdoba. También se valora la fiabilidad documental de cada vista, a la vez que se detectan significativas transformaciones de los lugares representados.

    Directory of Open Access Journals (Sweden)

    2016-11-01

    Full Text Available The recent death of David Bowie activated a memorial process which incites to retrace the cultural, social, aesthetic, of costume, fashion and art history of the last forty years. It’s impossible, therefore, not reflect on the mechanisms that led to the creation of he who in the collective imaginary is reductive to consider just a symbol of modern rock.Several books, prestigious magazines and important exhibitions devoted space to the infinite nuances of he who is defined not only icon but also idol, star, legend and myth. These terms have subtle interferences between them as Jean Jacques Wunenburger underlined and all refer to the concept of Mythology. Even if many authors stated the “disappearance of the myth” in the postmodern epoch (Jewett and Lawrence, the myth is one of those phenomena which involves the everyday life, also in the contemporary time.Certainly the ever closer relations between art, mass media and advertisement played a decisive role in restructuring the concept of myth, but didn’t essentially change its meaning. Actually, the mass reproducibility of images, instead of provoking the “fall of aura”, as stated by Walter Benjamin, seems to have increased the "sacred" magnetism of the images.The icon David Bowie is the result of a multifaceted and outstanding personality which involved and influenced every possible contemporary language - fashion, music, theatre, film, performance, video and more recently internet. As always the photographic gaze captured and crystallized over time the different visions making them eternal and “biting” in the meaning which Barthes clarified in his famous book.The intense collaboration with “the man who photographed the Seventies”, the English Mick Rock, produced images intended to write an important piece of the history of contemporary photography. Ziggy Stardust, the character masterfully interpreted and documented by Mick Rock, is the symbol of Bowie’s fascinating ability

  14. David Stafford-Clark (1916-1999): Seeing through a celebrity psychiatrist

    Science.gov (United States)

    Miller, Gavin

    2017-01-01

    This article uses the mass-media career of the British psychiatrist David Stafford-Clark (1916-1999) as a case study in the exercise of cultural authority by celebrity medical professionals in post-war Britain. Stafford-Clark rose to prominence in the mass media, particularly through his presenting work on medical and related topics for BBC TV and Radio, and was in the vanguard of psychiatrists and physicians who eroded professional edicts on anonymity. At the height of his career, he traded upon his celebrity status, and consequent cultural authority, to deliver mass media sermons on a variety of social, cultural, and political topics. Stafford-Clark tried to preserve his sense of personal and intellectual integrity by clinging to a belief that his authority in the public sphere was ultimately to be vindicated by his literary, intellectual, and spiritual significance. But as his credibility dwindled, he came to distrust the cultural intermediaries, such as broadcasters and publishers, who had supported him. PMID:28503668

    Walker, Michael J A

    2015-11-15

    David Triggle's scientific career began as a chemist, went through medicinal chemistry into pharmacology, and finally on to somewhat more philosophical interests in later years. It was a career marked by many contributions to all of those aspects of science. Chief amongst his many contributions, in addition to those in medicinal chemistry, was his work on the drugs known as calcium ion channel blockers or (calcium antagonists). In the calcium ion channel field he was a particularly instrumental figure in sorting out the mechanisms, actions and roles of the class of calcium channel blockers, known chemical and pharmacologically as the dihydropyridines (DHPs) in particular, as well as other calcium blockers of diverse structures. During the course of a long career, and extensive journeys into medicinal chemistry and pharmacology, he published voluminously in terms of papers, reviews, conference proceedings and books. Notably, many of his papers often had limited authorship where, as senior author it reflected his deep involvement in all aspects of the reported work. His work always helped clarify the field while his incisive reviews, together with his role in coordinating and running scientific meetings, were a great help in clarifying and organizing various fields of study. He has had a long and illustrious career, and is wellknown in the world of biomedical science; his contributions are appreciated, and well recognized everywhere. The following article attempts to chart a path through his work and contributions to medicinal chemistry, pharmacology, science, academia and students. Copyright © 2015 Elsevier Inc.

Mais precisamente, o texto destaca a estratégia de formalização adotada por David G. Champernowne em seu artigo intitulado "Unemployment, Basic and Monetary: the classical analysis and the keynesian", publicado em 1935-36 na Review of Economic Studies. Chamamos a atenção para o fato dele distinguir a teoria clássica da teoria de Keynes não apenas pelos pressupostos adotados por cada teoria, mas principalmente pela construção de subsistemas a partir de um sistema geral, com características recursivas (relações de causalidade distintas. As explicações "em prosa", a descrição algébrica das funções comportamentais e condições de equilíbrio e a ilustração por meio de diagramas, além da escolha de conjuntos específicos de variáveis para representar cada uma das teorias e suas diferentes versões são aspectos deste artigo de Champernowne que merecem uma análise mais minuciosa.

    Full Text Available El fenómeno de la delincuencia juvenil es un tema que aún en la actualidad sigue generando polémica; las líneas de investigación enfocan su esfuerzo en la búsqueda de las razones por las cuales un menor entra en el mundo delincuencial. Sin embargo, omiten la existencia de autores que dedicaron sus estudios a dar respuesta a tal cuestión. Un autor clave en el estudio del fenómeno delincuencial es el sociólogo estadounidense David Matza, pionero en las teorías de carácter social que pretenden dar respuestas a las incógnitas planteadas dentro de la temática juvenil; el presente artículo se enfocará en el análisis y reflexión de los principales postulados de su teoría de las subculturas delincuenciales, por medio de una perspectiva basada en la interacción, lo cual nos mostrará que es una subcultura a la par de la cultura convencional, con miembros que no distan de aquellos jóvenes que son considerados normales por la mayoría de la sociedad. Así se explica por qué algunos jóvenes se aproximan al quebrantamiento de la ley.

    Rafalowski, Chaim; Peleg, Kobi; Bin, Eli

    2010-07-01

    The activities of Magen David Adom (MDA) during the 2nd Lebanese War led to a series of conclusions (some established during the fighting) regarding the operational concept of the organization, the response to the needs of the team members, and the resource requirements. The fighting led to an update in the operational concept, moving to the smaller based operational unit--the station, creating a flexible concept, enabling response to various simultaneous scenes, quickly generating a common situational awareness, and relocation of resources to the more relevant events. TechnoLogy must support the operational concept. The response to stress-related victims should be part of the operational concept during conflict. Debriefing and learning processes are part of the response and enable adaptation to the changing reality. A comprehensive response to the needs of the team members is required, by relocation of family members, meeting the daily needs and preventing stress-related reactions among them. A rotation of leave of absence, central management of human resources and the management of volunteers--spontaneous and those who return to active work, are other components of this issue. The required resources--personal protective equipment, collective protection, command control and communications equipment, the supplies level and the different vehicles required for the operation, are important issues in the operational program of the organization. Collecting blood, maintaining a strategic stockpile and protecting the units, are all part of MDA missions.

  19. Theory of Money of David Ricardo: Quantity Theory and Theory of Value

    Directory of Open Access Journals (Sweden)

    Susumu Takenaga

    2003-01-01

    Full Text Available En lo que es necesario enfatizar, al caracterizar la teoría cuantitativa de David Ricardo, es en que ésta es una teoría de determinación del valor del dinero en una situación particular en la cual se impide que el dinero, sin importar cual sea su forma, entre y salga libremente de la circulación. Para Ricardo, la regulación del valor del dinero por su cantidad es un caso particular en el cual el ajuste del precio de mercado al precio natural requiere un largo periodo de tiempo. La determinación cuantitativa es completamente inadmisible, pero solo cuando el período de observación es más corto que el de ajuste. En todo caso, la determinación del valor del dinero rara vez es vinculada a su teoría del valor de las mercancías. Contrario a la interpretación aceptada comúnmente, Ricardo no aplicó a la determinación del valor del dinero una teoría del valor distinta de aquélla aplicada a las mercancías en general.

  20. El enigma de las montañas reales: propuesta narrativa de David Toscana

    Directory of Open Access Journals (Sweden)

    Iwona Kasperska

    2013-01-01

    Full Text Available The objective of this paper is to reflect on some features of David Toscana’s novel Los puentes de Königsberg. In this contribution by the Northern Mexican writer there are unusual parallelisms between different realities of the cities of Monterrey (Mexico and Königsberg (East Prussia, which become the basis of the structure of the novel. In this framework the author situates certain eccentric characters, providing them with a “double life”, a real Mexican one and an imaginary East-Prussian one, in order to contrast the cities and validate the superiority of Königsberg, the actual protagonist of the novel. Toscana uses selected criteria, such as scientific and cultural contributions by the cities, their different historical fates, and the moral attitudes of their inhabitants towards discrimination, war crimes and gender violence, which implies a severe critique of Monterrey’s society. The set of parallelisms between the cities is totally convincing as a fictional structure and emphasizes the most prominent quality of Toscana’s analysed prose.

  1. Review: David Lohmann (2003. Das Bielefelder Diakonie-Management-Modell [The Bielefeld Deaconry Management Model

    Directory of Open Access Journals (Sweden)

    Jürgen Rausch

    2006-01-01

    Full Text Available In six chapters, David LOHMANN makes suggestions for theological-ethical deaconry management, including a consideration of economic necessities. Through a qualitative comparison of documented sources, the author generates a theory of theological-ethical enterprise management. Following that, the author considers the theology of the deaconry in the context of TILLICH's model of believed realism and WICHERN’s theological concept of the inner mission. At the center of the examination lies a formulation of a cybernetic theory of deaconry theology. Of the available management models, the author favours the St. Galler model as the basic model of deaconry enterprise management. In doing so, the author lays out theological ground rules for the normative, strategic and operational levels of deaconry. In attempting to formulate this prospective deaconry management model through the consideration of the work of the two 20th century theologians and his own personal experience, the current needs and knowledge-base of specific deaconries are not considered. A systematic consideration of quantitative social research would have been a worthwhile supplement. In conclusion, the analysis develops a management model for deaconry enterprises that emphasizes the interdisciplinary aspects of theology and business economics. The book confirms the competitive value of a management model attuned to the theological and economic aspects of a deaconry. URN: urn:nbn:de:0114-fqs0601356

    Frost, Darrel R.; McDiarmid, Roy W.; Mendelson, Joseph R.

    2009-01-01

    The Point of View by Gregory Pauly, David Hillis, and David Cannatella misrepresents the motives and activities of the anuran subcommittee of the Scientific and Standard English Names Committee, contains a number of misleading statements, omits evidence and references to critical literature that have already rejected or superseded their positions, and cloaks the limitations of their nomenclatural approach in ambiguous language. Their Point of View is not about promoting transparency in the process of constructing the English Names list, assuring that its taxonomy is adequately reviewed, or promoting nomenclatural stability in any global sense. Rather, their Point of View focuses in large part on a single publication, The Amphibian Tree of Life, which is formally unrelated to the Standard English Names List, and promotes an approach to nomenclature mistakenly asserted by them to be compatible with both the International Code of Zoological Nomenclature and one of its competitors, the PhyloCode.

    Full Text Available A crescente utilização de materiais poliméricos bioreabsorvíveis em medicina, tem estimulado pesquisadores na área ortopédica na busca de soluções mais biológicas, substituindo artefatos tais como fios, hastes e placas metálicas por polímeros bioreabsorvíveis no tratamento de fraturas. Para tanto, resolveu-se estudar implantes da blenda de PLLA/PHBV (dois polímeros bioreabsorvíveis moldados em uma mini-injetora. Esses implantes foram utilizados para recuperação de fraturas de fêmur de coelhos e avaliados em comparação ao fio de Steinmann (aço inox, usado comercialmente. Após eutanásia com 6, 12 e 24 semanas de implantação dos artefatos, os ossos foram estudados com radiografias, exame histológico e ensaio mecânico, enquanto os implantes poliméricos foram submetidos a microscopia eletrônica de varredura (SEM, ensaio mecânico e calorimetria diferencial de varredura modular (MDSC. As radiografias mostraram calos ósseos bem formados, tanto com o uso da haste de polímero como com o controle metálico. O estudo histológico mostrou ausência de reações inflamatórias ou osteólise. O ensaio mecânico mostrou que a consolidação óssea ocorreu nos dois grupos. Tanto no ensaio mecânico como na calorimetria observou-se que a haste polimérica apresentou sinais de degradação progressiva no tempo estudado. Com os dados obtidos neste estudo, podemos afirmar que o implante PLLA/PHBV demonstrou ser efetivo na reparação de fraturas do fêmur de coelhos quando comparado com o controle metálico.The growing interest in medicine with the use of bioreabsorbable polymeric materials has been stimulating researchers from orthopedic area to develop more biological solutions, substituting threads, stems and metallic plates for bioreabsorbable polymers in the treatment of fractures. So, we decided to study implants of the PLLA/PHBV blends (two bioreabsorbable polymers moulded in a mini-injector. Those implants were used for

    Full Text Available As plantas ornamentais, em geral, e o gladíolo, em particular, são bastante suscetíveis às variações do nível de água no solo. No presente estudo foram avaliados os efeitos de diferentes níveis de tensão de água no solo sobre o crescimento e produção do gladíolo, em experimento realizado em casa-de-vegetação em Lavras, Minas Gerais. Esses efeitos foram caracterizados nas fases de crescimento vegetativo, espigamento e floração, por análises das seguintes medidas de crescimento: altura da planta, tamanho da haste floral e número de flores. O delineamento experimental foi o inteiramente casualizado em esquema de faixas, avaliando-se quatro níveis de tensão de água no solo (15, 25, 40 e 60 kPa em cada uma das três fases fenológicas da cultura, totalizando doze tratamentos e seis repetições. Os resultados mostraram que a altura da planta, tamanho da haste floral e o número de flores foram significativamente reduzidos pelo aumento dos níveis de tensão de água no solo, sendo os efeitos mais intensos nas fases de crescimento e espigamento. Os melhores resultados em relação ao tamanho da planta, da haste floral e número de flores, foram obtidos mantendo-se a tensão de água no solo próxima à capacidade de campo.The ornamental plants in general, and specially the gladiolus, are susceptible to variations of the soil water level. The effects of different soil water tensions on growth and production of gladiolus were evaluated in an experiment carried out in a greenhouse located in Lavras, Minas Gerais State, Brazil.

    Full Text Available Uma série de 103 casos de fraturas diafisárias complexas do fêmur foram tratadas com a haste intramedular bloqueada FMRP, no período de maio de 1987 a dezembro 1995. Das 103 fraturas, 67 eram cominutivas, 12 bifocais (segmentar, 4 espirais, 13 proximais e 21 distais, instáveis, rotacionalmente, da diáfise femoral. Do total dos casos, constatou-se 97 bloqueios estáticos e 6 dinâmicos. Dessas 97 estáticas, 7 foram dinamizadas durante a evolução. Clínica e radiográficamente a consolidação ocorreu em 97,09% dos casos, com média de 16,72 semanas e em 3 casos não houve consolidação. Houve 4 casos de infecção suspeita e 3 estabelecidas que foram debeladas e evoluíram para consolidação. Houve 81 casos de encurtamentos que variaram entre 0,5 a 4 cm com média de 1 cm. O encurtamento menor ou igual a 2 cm ocorreu em 73 casos. Desvio de alinhamento em qualquer plano acima de 10 º e igual a 15º foi observado em 8 pacientes. Houve 10 casos de deformidades rotacionais, porém nenhum caso acima de 10º. A incidência de infecção foi baixa e a de consolidação alta. A estabilização dessas fraturas complexas permitiu imediata mobilização do paciente, reabilitação precoce do membro e diminuição da permanência hospitalar, excetuando os politraumatizados. A haste FMRP permitiu o tratamento dessas fraturas sem o uso de intensificador de imagens e de fresas flexíveis com baixo custo operacional. Os resultados foram semelhantes aos obtidos com as hastes intramedulares bloqueadas que necessitam de aparelhagem técnica mais sofisticada, porém com vantagens para o paciente e a equipe cirúrgica.A series of 103 cases of complex femoral fracture were treated with FMRP (Faculdade de Medicina de Ribeirão Preto nail.

    Full Text Available O conhecimento da umidade do solo é de fundamental importância para a agricultura, sobretudo na determinação de sua variação, na otimização do manejo do solo e da água. Para medidas de umidade do solo existe tendência de utilização da técnica de TDR (Reflectometria no Domínio do Tempo que, de certa forma, é nova no Brasil. Colaborando com a difusão da técnica, estudou-se a possibilidade de utilização de sondas multi-haste segmentadas em um equipamento de TDR. O trabalho foi dividido em duas partes, em que na primeira, as performances de duas configurações de sonda foram analisadas e, na segunda parte, as sondas foram avaliadas durante o monitoramento da umidade em condições de laboratório e de campo. Foi possível verificar-se a viabilidade do uso de sondas multi-haste segmentadas na estimativa da umidade de um perfil de solo; entretanto, a utilização da Sonda 1, com segmentação de 0,10 m, ficou limitada à profundidade de 0,40 m, devido à dificuldade da interpretação dos picos de impedância em sua extremidade.The knowledge of soil water content is important for agriculture, mainly the determination of its changes in the soil profile in order to optimize irrigation management. The tendency to use the technique of TDR (Time Domain Reflectometry to measure the soil water content is relatively new in Brazil. To help the diffusion of this technique, the objective of this work was to study the possibility of using multi-wire probes with electrical impedance discontinuities in TDR equipment. The experiment was divided in to two parts. In the first one, the laboratory performance of two multi-wire probe configurations was studied; and in the second one, the evaluation of the probe reliability to monitor water content changes in porous media. The viability of the use of multi-wire probes to estimate the water content in the porous media profile was confirmed. However, the use of a probe with 0.10 m segmentation was

    Full Text Available BACKGROUND: Pain and dysfunction of the shoulder complex are commonly found physiotherapy practice. These musculoskeletal abnormalities are related to instability and inadequate kinematic function, that depend on the integrity of the muscle tissues. Thus, to enhance the results of exercise therapies, and prevent and attenuate pain and dynfunction, the use of oscillatory pole has been implemented in clinical practice. OBJECTIVES: The purpose of this study was to analyze the electromyographic (EMG activity of shoulder stabilizing muscles during exercises performed with an oscillatory and a non-oscillatory pole. METHODS: Twelve female volunteers, aged 20.4 years±1.9, participated in this study. EMG data were collected from upper trapezius (UT, lower trapezius (LT and middle deltoid (MD during three different exercises with an oscillatory and a non-oscillatory pole. The EMG signals were analyzed in the time domain through the calculation of Root Mean Square (RMS. The RMS values were normalized by the peak value obtained over all trials for each muscle. Statistical analysis was performed with repeated measures ANOVA and post-hoc of Bonferroni tests.

    Accuracy and precision of leaf positioning in multileaf collimators (MLCs) are significant factors for the accuracy of IMRT treatments. This study aimed to inves-tigate the accuracy and repeatability of the MLC leaf positioning via the DAVID invivo dosimetric system for dynamic and static MLC systems. The DAVID system was designed as multiwire transmission ionization chamber which is placed in accessory holder of linear accelerators. Each wire of DAVID system corresponds to a MLC leaf-pair to verify the leaf positioning accuracy during IMRT treatment and QA. In this study, verifications of IMRT plans of five head and neck (H&N) and five prostate patients treated in a Varian DHX linear accelerator with 80-leaf MLC were performed using DAVID system. Before DAVID-based dosimetry, Electronics Portal Imaging Device (EPID) and PTW 2D ARRAY dosimetry system were used for 2D verification of each plan. The measurements taken by DAVID system in the first day of the treatments were used as reference for the following measurements taken over the next four weeks. The deviations in leaf positioning were evaluated by "Total Deviation (TD)" parameter calculated by DAVID software. The delivered IMRT plans were originally prepared using dynamic MLC method. The same plans were subsequently calculated based on static MLC method with three different intensity levels of five (IL5), 10 (IL10) and 20 (IL20) in order to compare the performances of MLC leaf positioning repeatability for dynamic and static IMRT plans. The leaf positioning accuracy is also evaluated by analyzing DynaLog files based on error histograms and root mean square (RMS) errors of leaf pairs' positions. Moreover, a correlation analysis between simultaneously taken DAVID and EPID measurements and DynaLog file recordings was subsequently performed. In the analysis of DAVID outputs, the overall deviations of dynamic MLC-based IMRT calculated from the deviations of the four weeks were found as 0.55% ± 0.57% and 1.48% ± 0

    Full Text Available During the campaign which took place in 1983 at the site of Pontes - Trajan’s Bridge near Kostol, in the layer between a house from the second half of the 9th century and a house from the 11th century, a treasury consisting of medieval iron tools placed around, or inserted into, a bronze flagon was discovered in a shallow pit. The whole find was named Treasury B. At first, the flagon itself was dated into the period between the 6th and the 8th centuries, however, we have recently dated it into the 6th-7th century. The inscription on the neck of the vessel is a paraphrase of the 3rd verse from the 29th Psalm of David. This is proof that the flagon was a liturgical vessel. In this text we are trying to show that this flagon was analogous to the specimen from the treasury from Vrap in Albania, whose deposition during the third part of the 7th century is connected with the activity of Bulgarian Khan Kuber. The Byzantine vessel was a part of treasure plundered from the Avars, and the production of this flagon, just as of that one from Pontes, can be dated into the period between the 6th century and the first half or the middle of the 7th century.

    We reviewed our experience with aortic valve-sparing operations in Marfan syndrome during last 5 years. Between March 2004 and June 2009, 94 patients with aortic root aneurysms underwent valve-sparing operations. Of these, 37 (68% male) were diagnosed with Marfan syndrome, according to the Ghent diagnostic criteria. Mean age was 30 +/- 10 years (range, 11 to 59 years). Moderate/severe aortic regurgitation was present in 13%, and the mean diameter of the Valsalva sinuses was 50 +/- 4 mm (range, 42 to 62 mm). The David V modification was performed in the last 28 patients. Additional procedures were mitral valve repair in 6, tricuspid valve repair in 3, closure of septal atrial defect in 2, and closure of a patent foramen ovale in 13. Mean follow-up was 27 +/- 16 months (range, 1 to 61 months). There were no in-hospital deaths and no major adverse outcomes. One patient required implantation of a mechanical prosthesis during the same procedure because of moderate aortic regurgitation. One late death occurred. No patients required reoperation. In the last follow-up, 23 patients did not have aortic regurgitation, 12 had grade I, and 1 had grade II. No thromboembolic complications have been documented, and 97% of the patients are free from anticoagulation. Short-term and midterm results with the reimplantation technique for aortic root aneurysms in Marfan patients are excellent. If long-term results are similar, this technique could be the treatment of choice for these patients. 2010 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.

    The US Air Mobility Command (AMC) has tasked Pacific Northwest Laboratory (PNL) with supporting the US Department of Energy (DOE) Federal Energy Management Program's (FEMP) mission to identify, evaluate, and assist in acquiring all cost-effective energy resource opportunities (EROs) at the David Grant Medical Center (DGMC). This report describes the methodology used to identify and evaluate the EROs at DGMC, provides a life-cycle cost (LCC) analysis for each ERO, and prioritizes any life-cycle cost-effective EROs based on their net present value (NPV), value index (VI), and savings to investment ratio (SIR or ROI). Analysis results are presented for 17 EROs that involve energy use in the areas of lighting, fan and pump motors, boiler operation, infiltration, electric load peak reduction and cogeneration, electric rate structures, and natural gas supply. Typical current energy consumption is approximately 22,900 MWh of electricity (78,300 MBtu), 87,600 kcf of natural gas (90,300 MBtu), and 8,300 gal of fuel oil (1,200 MBtu). A summary of the savings potential by energy-use category of all independent cost-effective EROs is shown in a table. This table includes the first cost, yearly energy consumption savings, and NPV for each energy-use category. The net dollar savings and NPV values as derived by the life-cycle cost analysis are based on the 1992 federal discount rate of 4.6%. The implementation of all EROs could result in a yearly electricity savings of more than 6,000 MWh or 26% of current yearly electricity consumption. More than 15 MW of billable load (total billed by the utility for a 12-month period) or more than 34% of current billed demand could also be saved. Corresponding natural gas savings would be 1,050 kcf (just over 1% of current consumption). Total yearly net energy cost savings for all options would be greater than $343,340. This value does not include any operations and maintenance (O M) savings.

Typical current energy consumption is approximately 22,900 MWh of electricity (78,300 MBtu), 87,600 kcf of natural gas (90,300 MBtu), and 8,300 gal of fuel oil (1,200 MBtu). A summary of the savings potential by energy-use category of all independent cost-effective EROs is shown in a table. This table includes the first cost, yearly energy consumption savings, and NPV for each energy-use category. The net dollar savings and NPV values as derived by the life-cycle cost analysis are based on the 1992 federal discount rate of 4.6%. The implementation of all EROs could result in a yearly electricity savings of more than 6,000 MWh or 26% of current yearly electricity consumption. More than 15 MW of billable load (total billed by the utility for a 12-month period) or more than 34% of current billed demand could also be saved. Corresponding natural gas savings would be 1,050 kcf (just over 1% of current consumption). Total yearly net energy cost savings for all options would be greater than $343,340. This value does not include any operations and maintenance (O&M) savings.

    Valve-sparing root replacement (VSRR) is an established therapy for aortic root pathology. However, late aortic valve dysfunction requiring reoperation remains a primary concern of this procedure. This study examines risk factors for late aortic insufficiency (AI) and aortic stenosis (AS) after David V VSRR. A retrospective review from 2005 to 2015 at a US academic center identified 282 patients who underwent VSRR. Cox proportional hazards regression analysis was used to identify risk factors for late AI and AS after VSRR. The mean age was 46.4 years. Sixty-four patients (22.7%) had bicuspid valves, and 41 patients (14.5%) had Marfan syndrome. The incidence of reoperations was 27 (9.6%), and 42 cases (14.9%) presented with acute type A dissection. Operative mortality was 8 (2.8%). Seven-year survival was 90.9%. Seven-year cumulative incidence of reoperation, greater than 2+ AI and greater than moderate AS were 3.1%, 2.2%, and 0.8%, respectively. Multivariable analysis showed aortic root size 55 mm or larger (hazard ratio 3.44, 95% confidence interval: 1.27 to 9.29, p = 0.01) to be a risk factor for late AI whereas bicuspid valve (hazard ratio 16.07, 95% confidence interval: 3.12 to 82.68, p = 0.001) and cusp repair were found to be risk factors (hazard ratio 5.91, 95% confidence interval: 1.17 to 29.86, p = 0.03) for late AS. Valve-sparing root replacement can be performed with low operative risk and good overall long-term survival even in complex clinical settings. Durable valve function can be expected; however, aortic root size 55 cm or more, bicuspid valve anatomy, and cusp repair represent independent risk factors for late aortic valve dysfunction after these procedures.

    Full Text Available O enrolamento da fôlha é, presentemente, a moléstia de vírus de maior importância em relação à produção da batata-semente certificada, no Estado de São Paulo. Determinações relativamente precisas sôbre a ocorrência do virus em lotes de batata-semente certificada são necessárias para garantia dos lavradores que adquirem tais sementes e bom funcionamento do Serviço de Certificação. Os métodos de determinação baseados em amostras do produto depois de colhido são os que podem oferecer maior precisão, mas geralmente demandam um período de tempo que os tornam desvantajosos para a comercialização do produto. A determinação da ocorrência do vírus nos tubérculos de batata após colheita, com base em testes feitos com amostras de hastes das plantas produtoras, colhidas ao acaso, em fins de ciclo, tem-se mostrado extremamente prometedora nos testes efetuados e é considerada exequível mesmo para uso em larga escala. Os melhores resultados nas determinações foram obtidas usando-se Datura stramonium como planta-teste aos 40 dias de idade, para enxertia com as hastes das plantas a serem provadas, colhidas 60 a 70 dias depois de brotadas. Os sintomas desenvolvidos nos casos positivos são de fácil identificação, e as determinações podem ser obtidas dentro de 30 a 40 dias após a enxertia.Leaf roll is, at present, the most important virus problem in connection with the production of certified seed potato in São Paulo, Brazil. Leaf roll virus determinations based on samples obtained from seed lots can offer a high degree of accuracy, but generally demand a period of time that interferes with the seed potato sales to growers. The use of potato stems, collected at random late in the season, for grafting tests to determine the occurrence of the leaf roll virus in the planting and consequently in the tubers, is considered very promising for the conditions encountered in São Paulo and feasible even on a large scale.

    We investigated the impact of enclosure size and animal density on behavior and adrenocortical secretion in Père David's deer in Dafeng Nature Reserve, China. From February 15 to April 16 in 2004, we conducted two experiments. First, we studied maintenance behavior and conflict behavior of Père David's deer stags in a large enclosure (200 ha) with low animal density (0.66 deer/ha) and a small display pen (0.75 ha) with high animal density (25.33 deer/ha). The maintenance behavior we recorded included standing, locomotion, foraging and rest. During the behavioral observations, we collected fresh voided fecal samples from the stags periodically, and analyzed the fecal cortisol concentrations in those samples using radioimmunoassay technique. Second, we monitored the fecal cortisol concentrations of one group of stags (12 deer lived in an enclosure of 100 ha) before and after transferred into a small pen (0.5 ha). We found that in the first experiment: (1) there were significant differences in standing and rest whereas no significant differences of locomotion and foraging between the free-ranging group and the display group; (2) frequency of conflict behavior in the display group was significantly higher than those in the free-ranging group; and (3) fecal cortisol concentration of the display group (326.17+/-16.98 ng/g dry feces) was significantly higher than that of the free-ranging group (268.98+/-15.21 ng/g dry feces). In the second experiment, there was no significant difference of the fecal cortisol concentrations among sampling days, but the mean fecal cortisol concentration of the day after transferring (337.46+/-17.88 ng/g dry feces) was significantly higher than that of the day before transferring (248.44+/-7.99 ng/g dry feces). Comparison with published findings, our results indicated that enclosure size and animal density affect not only behaviors, but also adrenocortical secretion in Père David's deer. Small living space with high animal density may

  11. Hear After: Matters of Life and Death in David Tudor’s Electronic Music

    Full Text Available In David Tudor’s electronic music, home-brew modular devices were carefully connected together to form complex feedback networks wherein all components—including the composer/performer himself—could only partially ‘influence’ one another. Once activated, the very instability of mismatched connections between the components triggered a cascade of signals and signal modulations, so that the work “composed itself,” and took “a life of its own.” Due to this self-producing, perpetuating nature of his works, Tudor insisted on what he called “the view from inside,” focusing more on the internal observation of his devices and sound than in materials external to the immanence of performance. When Tudor passed away in 1996, it became apparent that the sheer lack of resources outside the work—scores, instructions, recordings, texts—had made many of his music impossible to perform in his absence. The works that took a life of their own could not survive their composer’s death partially because of his utter reliance on them to do their work. By connecting often mismatched resources obtained from extended research on Tudor, this paper presents modular observations that seem to offer certain perspectives on the issue of life and death surrounding Tudor’s music. A comparison with developments in systems theory, most notably autopoiesis, outlines a mechanism for the endless life of sounds that compose themselves. Moving out of this theoretical reflection, a fieldwork report of an ongoing attempt to ‘revive’ some of Tudors works is offered. This report demonstrates the observer shifting from one ‘inside’ to another—from an electronic circuitry inside a particular device, to a network composed of several devices, and further into the activation of a composite instrument. Meandering away from the archives, the composer’s “view from inside” of his electronic devices is set side by side with recent insights of object

    Full Text Available La interpretación de la novela de Charles Dickens David Copperfield se propone destacar las formas en que la literatura somete a debate bosquejos de subjetividad e interacción. El interés central es la asignación cultural de atributos individuales que derivan de esquemas predeterminados sobre valores personales y de formas de vida. A la construcción social del prejuicio se le brinda especial atención. El hilo del análisis lo lleva la interacción entre la figuras narrativas de David Copperfield y Urias Heep, pues conforman antípodas reflejo de antagonismos sociales. La configuración de contrastes entre las características de los personajes –los proyectos que encarnan y sus destinos– ofrece un campo para el estudio de las orientaciones para la acción en la vida cotidiana. Tal configuración prevé ordenamientos de la experiencia. Se hace énfasis en los elementos fundadores de una jerarquía de estilos y mundos de vida, que a su vez muestran cómo diferentes niveles simbólicos están comprometidos en la asignación de roles sociales y sus significados para un colectivo.

    This article applies the moral sentimentalism founded by David Hume to the moral status of the embryo. It will attempt to explain the paradoxical fact that in Germany abortion is common and socially accepted while preimplantation genetic diagnosis is banned with the aid of an approach based on moral sentimentalism. David Hume established the thesis that the human being is guided by the emotions and not by reason when making moral decisions. Scientific innovations often create a feeling of anxiety. Consequently, the initial moral judgment about it is negative. Due to this habit, the innovation is often accepted after a phase of indifference. This phenomenon has been observed in the case of heart transplantation, as well as for IVF. Consequently, the apparent contradiction in the varying degrees of the embryo's worthiness of protection in the womb and in the Petri dish is due to the simple fact that these are different stages of habituation. Therefore, the ethics of Hume cannot stipulate the embryo's moral status for once and for all; however, they can paradoxically raise the ongoing current debate to a more rational level through the insight that the underlying moral concepts are not based on reason alone.

    Full Text Available With its profound implications, Brexit is set to be the defining issue for the United Kingdom (UK and one of the most unique challenges that the European Union (EU and its member states have ever faced.  It was under the premiership of the former Prime Minister David Cameron that Britain’s relationship with the EU took such a dramatic turn. As it is essential, now more than ever, to understand the intriguing issue of Cameron’s European legacy, this article aims to deepen our understanding of his EU policy and provide key insights into the logic of his European dilemmas. As such, it explores how Cameron’s EU policy evolved under his Conservative Party leadership and investigates patterns of continuity and discontinuity in his EU discourse. More specifically, the inquiry compares three stages of Cameron’s EU policy corresponding with his three cabinets 1 shadow cabinet (2005-2010; 2 first cabinet (Cameron–Clegg coalition; 2010-2015; and 3 second cabinet (single-party ministry; 2015-2016. In each of these stages, attention is primarily given to trends, hallmarks and strategies of his European policy. The article concludes that whilst continuity can be detected in David Cameron’s EU policies throughout the whole tenure of his Conservative Party leadership, his EU strategies and tactics were marked by substantial discontinuity.

    Full Text Available Japan has often been portrayed by orientalist stereotypes, as famously framed by Edward Said, that were mainly constituted within Europe and North America. There are two distinct streams of orientalist discourse around Japan: traditional Orientalism and techno-Orientalism. Here the West speaks of the Other/the non-West rather than allowing it to speak for itself. In regards to the discourse of ‘Otherness’, another interesting phenomenon is Japan’s self-Orientalising: through the internalisation of the Western Orientalist discourse, Japan identifies itself and constructs its own subjectivity. In his literary works, the author David Mitchell attempts to subvert the conventional orientalist approach to describe Japan while concurrently maintaining his position as a British observer. He makes use of Western perspectives to cater to his Western readers’ preference for Japan’s traditional and cultural elements, and yet at the same time attempts to subvert stereotypes. Mitchell’s approach is reminiscent of Japanese author Murakami Haruki’s use of both ‘Japaneseness’ and ‘un-Japaneseness’ in his works. Mitchell also learnt the importance of the use of the subjective narrative voice from Murakami. In this article, I examine how David Mitchell, as a western author, attempts to go beyond orientalist stereotypes, and how his writing is influenced by Murakami Haruki.

    Full Text Available Apesar da expressiva evolução da ortopedia veterinária nos últimos anos, as fraturas de ossos longos em grandes animais são constante desafio para o médico-veterinário. O presente estudo é parte da proposta de desenvolvimento de um sistema de haste intramedular polimérica, de baixo custo e fácil aplicação, para uso em bovinos jovens e neonatos. Os objetivos foram avaliar, in vivo, hastes de poliacetal e poliamida para imobilização de fraturas femorais em bovinos jovens. Cinco bezerros machos foram submetidos à anestesia geral e tiveram os fêmures esquerdos fraturados e, em seguida, imobilizados, utilizando-se uma haste cilíndrica de poliacetal ou poliamida inserida no canal intramedular e bloqueada por quatro parafusos corticais de aço inoxidável, inseridos na diáfise em seu sentido lateral-medial e igualmente distribuídos distal e proximal à linha de fratura. Durante um período de 60 dias pós-cirúrgico, os animais foram avaliados por meio de exames clínicos e radiográficos. Houve fratura em quatro das cinco hastes de poliacetal implantadas pela primeira vez e em duas das quatro hastes de poliamida que foram implantadas após a quebra das de poliacetal. Todas as falhas ocorrerem nas primeiras duas semanas de imobilização. Não foram verificados quaisquer sinais de rejeição aos materiais usados.

    Full Text Available This article discusses Michael Berkeley’s first opera, Baa Baa Black Sheep: A Jungle Tale. Premiered under the baton of Paul Daniel on July 3rd 1993 at the Cheltenham International Festival of Music, this opera is based on two texts by Rudyard Kipling: The Jungle Books (1894-1895 and “Baa, Baa, Black Sheep” from the short story collection Wee Willie Winkie and Other Stories, first published in 1888. The libretto was penned by the Australian poet, novelist, playwright and librettist, David Malouf. After a brief survey of some of the earliest transpositions of The Jungle Books, I analyse the way David Malouf deals with both texts. “Baa Baa Black Sheep” is used as the central element of his libretto, and episodes and characters from The Jungle Books are incorporated to draw parallelism between the main topics of the two texts. Both Malouf’s endeavour and Berkeley’s, through the music, aims at deconstructing the preposterous oldest transpositions of The Jungle Books and at focusing on the key elements of Kipling’s famous book, notably identity and hybridism, two important themes of colonial and postcolonial literature. The aim of David Malouf and Michael Berkeley is to address an adult audience and show that The Jungle Books are not only aimed at children as Disney’s or Baden Powell’s appropriations of the work could wrongly make us believe.Cet article porte sur Baa Baa Black Sheep: A Jungle Tale, le premier opéra de Michael Berkeley.

    Full Text Available O tratamento de algumas das fraturas da criança tem sofrido modificações nos últimos anos, com o objetivo de obtenção de resultados mais satisfatórios, restrição do tempo de incapacidade e para melhor corresponder às expectativas da família. Isso é especialmente válido para as fraturas diafisárias de alguns ossos longos com o tratamento feito por hastes intramedulares elásticas. Esse tratamento é de baixa morbidade, respeita a biologia e a biomecânica da fratura e permite consolidação óssea por mecanismo secundário, com a formação de calo ósseo. Entretanto, requer implantes, instrumental e conhecimento técnico do cirurgião, pois os maus resultados relacionam-se diretamente com falhas técnicas. Atualmente, os ossos que mais se prestam para esse tipo de fixação, em relação à prioridade, são: fêmur, rádio, ulna, tíbia e úmero. O objetivo deste texto de atualização foi analisar a literatura e fornecer informações fundamentais para o conhecimento do método.The treatment of some fractures in children has changed over the last years aiming at improving results, shortening the time of physical limitation, and meeting family expectations. This is particularly true when long bone shaft fractures are involved and when treatment is carried out with elastic nails. This technique carries low morbidity, respects the biology and the biomechanics of the reparative process and allows secondary healing with osseous callus formation. Nevertheless, the technique requires adequate surgical implants, proper instruments and trained surgeons, since complications are related mainly to technical pitfalls. The technique has been used for the following bones: femur, radius and ulna, tibia and humerus. The objective of the present update was to review and to analyze the literature so as to present basic information about the treatment of diaphyseal fractures of some long bones of children with flexible nails.

  1. Blind haste: As light decreases, speeding increases.

    Directory of Open Access Journals (Sweden)

    Emanuel de Bellis

    Full Text Available Worldwide, more than one million people die on the roads each year. A third of these fatal accidents are attributed to speeding, with properties of the individual driver and the environment regarded as key contributing factors. We examine real-world speeding behavior and its interaction with illuminance, an environmental property defined as the luminous flux incident on a surface. Drawing on an analysis of 1.2 million vehicle movements, we show that reduced illuminance levels are associated with increased speeding. This relationship persists when we control for factors known to influence speeding (e.g., fluctuations in traffic volume and consider proxies of illuminance (e.g., sight distance. Our findings add to a long-standing debate about how the quality of visual conditions affects drivers' speed perception and driving speed. Policy makers can intervene by educating drivers about the inverse illuminance‒speeding relationship and by testing how improved vehicle headlights and smart road lighting can attenuate speeding.

  3. Last Words: David's Mars Disarmed by Venus and the Graces (1824. Subjectivity, Death, and Postrevolutionary Late Style

    Padiyar, Satish

    2011-06-01

    Full Text Available Completed as he was approaching death in 1825, Jacques-Louis David's final refractory history painting is an intricate summation of a life in politics and painting. The article attempts to re-interpret the canvas in relation to the dual problem of 'late style' and the condition of exile. I argue that this history painting invokes the metaphor of non-sex for the condition of exile; and as a late gesture stages an anomalous return to a pre-lapsarian eighteenth century. The painting, I conclude, reveals less the transcendent subjectivity of an artist approaching biological death, than the critical disarming of a once-radical neoclassical aesthetic itself, in its tragic late phase.

  4. A philosophical analysis of David Orr's theory of ecological literacy: biophilia, ecojustice and moral education in school learning communities

    Mitchell, Debra B.; Mueller, Michael P.

    2011-03-01

    In his writings, David Orr claims that the US is in an "ecological crisis" and that this stems from a crisis of education. He outlines a theory of ecological literacy, a mode by which we better learn the ecology of the Earth and live in a sustainable manner. While emphasizing a shock doctrine, the diagnosis of "crisis" may be correct, but it is short-lived for children and adults of the world. In this philosophical analysis of Orr's theory, it is argued that we move beyond the perspective of crisis. By extending Orr's ecological literacy with biophilia and ecojustice and by recognizing the importance of experience-in-learning, science education is envisioned to incorporate values and morals within a longer term ideology of educational reform.

    Valve-sparing root replacement (the David procedure) is a valuable alternative to conventional aortic root replacement with a composite graft, especially in patients whose aortic valve leaflets have not been altered. However, reintervention rates are higher than are those associated with composite graft implantation. In this report, we present the case of a patient who had undergone valve-sparing root replacement 2 years earlier and was admitted to our hospital with myocardial infarction and cardiogenic shock secondary to coronary ostial button dissection, aortic pseudoaneurysm formation, and severe left main coronary artery compression. To our knowledge, this case is exceedingly rare. Rather than attempt local reconstruction of the mouth of the pseudoaneurysm, we excised the lesion, the aortic valve, and the graft, and we successfully implanted a composite aortic graft with a mechanical aortic valve.

  6. Between a Rock and a Blue Chair: David Hockney’s Rocky Mountains and Tired Indians (1965

    Directory of Open Access Journals (Sweden)

    2017-04-01

    Full Text Available Travel and cultural exchange between the United Kingdom and the United States of America became a key feature of the 1960s, shaping the world view of many a British artist, curator, architect, writer, film-maker, and academic. Against that wider backdrop, I offer here a focused reading of David Hockney’s 1965 painting, Rocky Mountains and Tired Indians. With its faux-naive idiom and overt but quirkily un-modern American theme, the work conveys the artist’s singular take on what it felt like to be a Brit at large in the US, an environment at once wondrously exotic and at times strikingly banal. Close analysis discloses Hockney’s rich repertoire of artistic and literary allusions in Rocky Mountains, and the meanings and associations these may have encapsulated.

    Full Text Available A consolidação do sistema de semeadura direta trás grandes benefícios ao meio ambiente e, também, é notável a redução dos custos de produção devido a desnecessidade das operações como aração, subsolagem, escarificação e gradagem. Porém, nesse sistema se têm muitos problemas relacionados a compactação das camadas superficiais em função do tráfego de máquinas e a consorciação lavoura-pecuária. A solução encontrada pelos agricultores tem sido a substituição, na semeadora-adubadora, do sulcador disco duplo pela haste sulcadora que atua em profundidades superiores. O presente estudo teve como objetivo avaliar diferentes profundidades de trabalho da haste sulcadora, analisando o consumo de combustível, força de tração, índice de patinagem, potência na barra de tração, consumo específico de combustível e capacidade de campo teórica de um trator agrícola tracionando uma semeadora-adubadora em solo compactado pela integração lavoura-pecuária. Os tratamentos foram 100, 150, 200 e 250 mm de profundidade de trabalho da haste sulcadora, sendo os ensaios desenvolvidos no Departamento de Engenharia da Universidade Federal de Lavras, utilizando delineamento experimental de blocos, casualisados, composto por quatro tratamentos e três repetições. Dessa forma, conclui-se que o aumento da profundidade de trabalho da haste sulcadora em semeadoras-adubadoras de semeadura direta de milho em solos compactados ocorre o aumento no consumo de combustível, no índice de patinagem e no esforço de tração dos tratores agrícolas. Porém, quando a ponteira da haste sulcadora trabalhou posicionada 50 mm abaixo da camada mais compactada se teve reduções nos parâmetros força de tração e índice de patinagem, aumentando a capacidade de campo teórica.The direct sowing system brings many benefits to the environment and also reduction in production costs, since operations such as plowing, subsoiling, chiseling and harrowing

    The David aortic valve-sparing reimplantation (AVr-D) operation is increasingly being used in patients with aortic root aneurysmal disease and pliable aortic cusps. The objective of this study was to assess our early and medium-term outcomes with the AVr-D operation. Between 2003 and 2011, a total of 179 patients underwent AVr-D procedures. The mean patient age was 49.7 ± 15.1 years, and 23.5% (n = 42) were females. Marfan syndrome was present in 17.3% of patients (n = 31), and acute Type A aortic dissection in 15.6% (n = 28). Clinical follow-up was 100% complete and was 1.8 ± 1.6 years (0 days to 7.5 years) long. Echocardiographic follow-up was performed 2.2 ± 1.5 years (0 days to 7.5 years) postoperatively and was 77% complete. Early mortality was 1.1% (n = 2), with both deaths occurring in patients with Type A dissection. Pre-discharge echocardiography revealed no patients with >2+ aortic insufficiency (AI), 19.6% of patients (n = 34) with 1+ or 2+ AI and 80.4% of patients (n = 145) with trace or no AI. Left ventricular end-diastolic diameters decreased significantly from 5.6 ± 0.9 to 5.1 ± 0.8 cm early postoperatively (P valve re-replacement during follow-up, two due to early endocarditis and two due to non-coronary leaflet prolapse in Marfan patients. Five-year freedom from aortic valve reoperation was 95.9 ± 2.0%. AVr-D is associated with a low mortality and morbidity rate, even in patients with Type A aortic dissection. Although a slightly higher rate of recurrent AI may be present in patients with Marfan syndrome, freedom from recurrent AI and reoperation remains excellent during medium-term follow-up. The David operation should be considered the gold standard for patients with proximal aortic root pathology (aneurysm or dissection) and pliable aortic cusps.

  16. Urban common space, heterotopia and the right to the city: Reflections on the ideas of Henri Lefebvre and David Harvey

    Orlando Alves dos Santos Junior

    2014-05-01

    Full Text Available A city’s common spaces are appropriated by capital that aims to guarantee the conditions necessary for the production-reproduction of capitalist relations. In this context, the challenge is to imagine and construct a very different type of city capable of breaking away from the dynamic of capital, founded on new forms of appropriation of the city, which implies articulating both theory and praxis. For this to occur, however, it is necessary to create new knowledge about the city and a strong anti-capitalist social movement focused on the transformation of daily urban life and involving new forms of appropriation of urban common spaces. It is in this context, and from a dialectic perspective, that this article articulates the ideas of Henri Lefebvre and David Harvey, seeking to contribute to an understanding of the production processes of space in contemporary capitalism, the discussion of the future of cities and perspectives on transition. To do so, the article addresses four central ideas: (i the dialectic conception of space to problematize the production and appropriation of urban common spaces; (ii the recognition of urban common spaces as spaces traversed by contradictions, disputes and material and symbolic conflicts among different agents; (iii the right to the city as a need and as a utopian project; and (iv the challenge of articulating heterotopic practices from the perspective of creative rebellion for the right to the city and the transition to a new urban future.

  17. Sex-Age Related Rumination Behavior of Père David's Deer under Constraints of Feeding Habitat and Rainfall.

    Directory of Open Access Journals (Sweden)

    Zhongqiu Li

    Full Text Available Extensive studies have been conducted on the rumination behavior of domestic herbivores. However, studies on wild animals are limited, particularly wild animals with specific ruminating parameters. In this study, Père David's deer, a previously extirpated species, was observed to analyze the effects of sex-age, feeding habitat, and rainfall on rumination behavior in the Dafeng Nature Reserve, China. Rumination behavior was investigated based on four parameters: proportion of bedding time spent chewing, bolus processing time (s/bolus, chewing frequency (chews/bolus, and chewing rate (chews/s. Results showed that all three factors affect rumination behavior. The extent of their effects varied based on the four rumination parameters. Chewing rate and frequency decreased based on sex-age levels, i.e., from fawns to juvenile female, juvenile male, adult female, stag, and harem holder. Therefore, body size played a major role in shaping rumination behavior. Deer found in grasslands could chew faster compared with deer found in woodlands. This result might be caused by the effects of dietary composition and sunlight intensity. A deer spends a longer time ruminating while bedding during rainy days compared with rainless days to maximize energy and nutrition intake and compensate for the loss of feeding time during rainy days. Therefore, rumination behavior is plastic and is shaped by intrinsic and extrinsic factors.

  18. ‘The Realer, More Enduring and Sentimental Part of Him’: David Foster Wallace’s Personal Library and Marginalia

    Directory of Open Access Journals (Sweden)

    John Roache

    2017-03-01

    Full Text Available This article asks what kind of relationship critics can posit between, on the one hand, David Foster Wallace’s personal library and marginalia and, on the other hand, his published works of fiction. The controversy surrounding Maria Bustillos’ 2011 reading of annotations in a selection of Wallace’s self-help texts – one result of which was the redaction of those texts from the archive – has served to reinforce the conventional critical understanding of authorly marginalia as a form of personal revelation or truth, and, by extension, as a kind of allegorical key to the respective literary oeuvre. However, this article contends that such a straightforward model of interpretation is unsettled by a reading of the marginalia alongside Wallace’s novel 'Infinite Jest' and his short story ‘Good Old Neon.’ The article concludes that, once the annotations are placed into this more dynamic relation with the fiction, such seemingly fundamental and potentially ‘therapeutic’ notions as truth, origin, and the ‘inner self’ are actually shown to be intertextually and ideologically entangled with a set of popular North American discourses that not only traverse Wallace’s library and oeuvre, but continue to shape his reception inside and outside the academy.

    1996-11-01

    This paper presents an interview with Dr. David Satcher of the US Centers for Disease Control and Prevention (CDC) on the issue of infectious and chronic diseases. The problem of new and reemerging infectious diseases around the world, particularly in developing countries, is discussed. While drug resistant malaria and sporadic outbreaks of Ebola in Africa have alarmed health programs, AIDS is the major emerging infectious disease throughout the world. Microorganisms have a way of surviving: they mutate, they adapt, and they emerge. The CDC¿s major partner in the global response to emerging infections is WHO. The CDC has learned lessons from its experience with AIDS and Ebola virus events. A system of domestic surveillance and global prevention should be developed. Poverty, hunger and malnutrition may contribute to the rise of chronic diseases in developing countries. The introduction of richer diets higher in cholesterol in combination with a sedentary lifestyle also will also lead to more chronic diseases among people in developing countries. In the future, smoking will have a greater impact on mortality than will any other factor in these countries. Infectious diseases are much less predictable. Drug resistant microorganisms and urbanization counterbalance the development of vaccines. The U.S. health care system wrongly prioritizes tertiary care while spending only 1% of its health budget on the prevention of diseases. Dr. Satcher would like to see the implementation of programs dealing with human behavior, sanitation, immunization and health education as preventive measures.

  20. Magnetization process and magnetocaloric effect in geometrically frustrated Ising antiferromagnet and spin ice models on a 'Star of David' nanocluster

    2018-04-01

    Magnetic and magnetocaloric properties of geometrically frustrated antiferromagnetic Ising (IA) and ferromagnetic spin ice (SI) models on a nanocluster with a 'Star of David' topology, including next-nearest-neighbor (NNN) interactions, are studied by an exact enumeration. In an external field applied in characteristic directions of the respective models, depending on the NNN interaction sign and magnitude, the ground state magnetization of the IA model is found to display up to three intermediate plateaus at fractional values of the saturation magnetization, while the SI model shows only one zero-magnetization plateau and only for the antiferromagnetic NNN coupling. A giant magnetocaloric effect is revealed in the IA model with the NNN interaction either absent or equal to the nearest-neighbor coupling. The latter is characterized by abrupt isothermal entropy changes at low temperatures and infinitely fast adiabatic temperature variations for specific entropy values in the processes when the magnetic field either vanishes or tends to the critical values related to the magnetization jumps.

  1. Expanding the body mass range: associations between BMR and tissue morphology in wild type and mutant dwarf mice (David mice).

    2007-02-01

    We sought to identify associations of basal metabolic rate (BMR) with morphological traits in laboratory mice. In order to expand the body mass (BM) range at the intra-strain level, and to minimize relevant genetic variation, we used male and female wild type mice (C3HeB/FeJ) and previously unpublished ENU-induced dwarf mutant littermates (David mice), covering a body mass range from 13.5 g through 32.3 g. BMR was measured at 30 degrees C, mice were killed by means of CO(2 )overdose, and body composition (fat mass and lean mass) was subsequently analyzed by dual X-ray absorptiometry (DEXA), after which mice were dissected into 12 (males) and 10 (females) components, respectively. Across the 44 individuals, 43% of the variation in the basal rates of metabolism was associated with BM. The latter explained 47% to 98% of the variability in morphology of the different tissues. Our results demonstrate that sex is a major determinant of body composition and BMR in mice: when adjusted for BM, females contained many larger organs, more fat mass, and less lean mass compared to males. This could be associated with a higher mass adjusted BMR in females. Once the dominant effects of sex and BM on BMR and tissue mass were removed, and after accounting for multiple comparisons, no further significant association between individual variation in BMR and tissue mass emerged.

    Science.gov (United States)

    Robertson, Frances

    2013-09-01

    This paper examines codes of representation in nineteenth century engineering in Britain in relation to broader visual culture. While engineering was promoted as a rational public enterprise through techniques of spectacular display, engineers who aimed to be taken seriously in the intellectual hierarchies of science had to negotiate suitable techniques for making and using images. These difficulties can be examined in the visual practices that mark the career of engineer David Kirkaldy. Beginning as a bravura naval draughtsman, Kirkaldy later negotiated his status as a serious experimenter in material testing science, changing his style of representation that at first sight seems to be in line with the 'objective' strategy in science of getting nature to represent herself. And although Kirkaldy maintained a range of visual styles to communicate with different audiences, making rhetorical use of several technologies of inscription, from hand drawing to photography, nevertheless, his work does in fact demonstrate new uses of the concept of objectivity in representation when up against the practices of engineering. While these might seem merely pragmatic in comparison to the ethical weight given to the discourse of objective representation in science, in the messy world of collapsing bridges and law suits, virtuous engineers had to develop various forms of visual knowledge as practical science. This was not 'applied science' but a differentiated form of enquiry whose complexities hold as much interest as the better known visual cultures of late nineteenth century science or art.

    The aortic valve-sparing David procedure has been applied to the elective treatment of patients with aortic aneurysms with excellent results. The use of this technique in patients with acute aortic dissection type A (AADA) is still a matter of debate. We present our long-term experience with 109 patients with AADA who had the valve-sparing David I procedure. Between July 1993 and October 2015, 109 patients with AADA had the valve-sparing David I procedure at our centre. We conducted a retrospective review with follow-up. The mean age was 54 ± 12 years; 78 (72%) patients were men. Marfan syndrome was present in 6 (5%) patients and bicuspid aortic valve in 3 (3%). Only 4 (4%) patients received the isolated David procedure; 50 (46%) underwent additional proximal, 13 (12%) subtotal and 42 (39%) total aortic arch replacement. The in-hospital mortality rate was 11% ( n  = 12). Intraoperative/discharge echocardiography showed aortic insufficiency ≤ I° in 93 of 97 patients (96%). Mean follow-up time was 8.3 ± 5.7 years. The survival rate after discharge at 1, 5 and 10 years was 94%, 90% and 78%, respectively. Thirteen percent ( n  = 13) of patients underwent valve-related reoperation. Freedom from valve-related reoperation at 1, 5 and 10 years was 96%, 88% and 85%, respectively. Compared to patients who underwent the David I procedure for any reason other than AADA, there were no significant differences in long-term survival rates ( P  = 0.29) and freedom from a valve-related reoperation ( P  = 0.39). The valve-sparing David I procedure has acceptable long-term results even in emergent operations for AADA and is not inferior when performed in elective settings. © The Author 2017.

    In 1997 an internally supported but unfunded pilot project at the Victorian Institute of Forensic Medicine (VIFM) Australia led to the development of a computer system which closely mimicked Interpol paperwork for the storage, later retrieval and tentative matching of the many AM and PM dental records that are often needed for rapid Disaster Victim Identification. The program was called "DAVID" (Disaster And Victim IDentification). It combined the skills of the VIFM Information Technology systems manager (VW), an experienced odontologist (JGC) and an expert database designer (JC); all current authors on this paper. Students did much of the writing of software to prescription from Monash University. The student group involved won an Australian Information Industry Award in recognition of the contribution the new software could have made to the DVI process. Unfortunately, the potential of the software was never realized because paradoxically the federal nature of Australia frequently thwarts uniformity of systems across the entire country. As a consequence, the final development of DAVID never took place. Given the recent problems encountered post-tsunami by the odontologists who were obliged to use the Plass Data system (Plass Data Software, Holbaek, Denmark) and with the impending risks imposed upon Victoria by the decision to host the Commonwealth Games in Melbourne during March 2006, funding was sought and obtained from the state government to update counter disaster preparedness at the VIFM. Some of these funds have been made available to upgrade and complete the DAVID project. In the wake of discussions between leading expert odontologists from around the world held in Geneva during July 2003 at the invitation of the International Committee of the Red Cross significant alterations to the initial design parameters of DAVID were proposed. This was part of broader discussions directed towards developing instruments which could be used by the ICRC's "The Missing

  7. A novel HURRAH protocol reveals high numbers of monomorphic MHC class II loci and two asymmetric multi-locus haplotypes in the Père David's deer.

    Full Text Available The Père David's deer is a highly inbred, but recovered, species, making it interesting to consider their adaptive molecular evolution from an immunological perspective. Prior to this study, genomic sequencing was the only method for isolating all functional MHC genes within a certain species. Here, we report a novel protocol for isolating MHC class II loci from a species, and its use to investigate the adaptive evolution of this endangered deer at the level of multi-locus haplotypes. This protocol was designated "HURRAH" based on its various steps and used to estimate the total number of MHC class II loci. We confirmed the validity of this novel protocol in the giant panda and then used it to examine the Père David's deer. Our results revealed that the Père David's deer possesses nine MHC class II loci and therefore has more functional MHC class II loci than the eight genome-sequenced mammals for which full MHC data are currently available. This could potentially account at least in part for the strong survival ability of this species in the face of severe bottlenecking. The results from the HURRAH protocol also revealed that: (1 All of the identified MHC class II loci were monomorphic at their antigen-binding regions, although DRA was dimorphic at its cytoplasmic tail; and (2 these genes constituted two asymmetric functional MHC class II multi-locus haplotypes: DRA1*01 ∼ DRB1 ∼ DRB3 ∼ DQA1 ∼ DQB2 (H1 and DRA1*02 ∼ DRB2 ∼ DRB4 ∼ DQA2 ∼ DQB1 (H2. The latter finding indicates that the current members of the deer species have lost the powerful ancestral MHC class II haplotypes of nine or more loci, and have instead fixed two relatively weak haplotypes containing five genes. As a result, the Père David's deer are currently at risk for increased susceptibility to infectious pathogens.

    Full Text Available The purpose of this work was evaluating the energetic demand of a seeder-fertilizer machine as a function of the type and handling of vegetal covering culture and of the fertilizer deposition shank depth. A Valtra BM100 tractor was used implemented to pull a high precision seeder-fertilizer machine with four ranks of seeding, spaced 0.9 m for maize culture. Experiment was conducted with design in randomized blocks in factorial plots, in the Laboratory of Machines and Agricultural Mechanization experimental area (LAMMA of UNESP-Jaboticabal, using two covering cultures (black-mucuna and crotalaria, three handlings of this covering, two mechanical (straw crusher and roller knife and one chemical (pulverization of herbicide, performed 120 days after seeding of covering cultures and three depths of fertilizer deposition shank, completing 18 treatments, with four repetitions, totaling 72 observations. Parameters of displacement speed, gliding, force on traction bar, peak force, power on pulling bar and fuel consumption were evaluated. It was possible to conclude that force on traction bar was less for depths of 0.11 and 0.14 m of fertilizer plough shank, the same occurring for peak force, power on traction bar and volumetric consumption. The specific consumption was lower at a depth of 0.17 m of fertilizer plough shank. Covering cultures and their handlings did not interfere in the performance of machines under inquiry.O trabalho teve por objetivo avaliar a demanda energética de uma semeadora-adubadora, em função do tipo e manejo da cultura de cobertura vegetal e da profundidade da haste de deposição de adubo.

    The study objective was to determine whether recurrent or residual mild aortic regurgitation, which occurs after valve-sparing aortic root replacement, progresses over time. Between 2003 and 2008, 154 patients underwent Tirone David-V valve-sparing aortic root replacement; 96 patients (62%) had both 1-year (median, 12 ± 4 months) and mid-term (62 ± 22 months) transthoracic echocardiograms available for analysis. Age of patients averaged 38 ± 13 years, 71% were male, 31% had a bicuspid aortic valve, 41% had Marfan syndrome, and 51% underwent aortic valve repair, predominantly cusp free margin shortening. Forty-one patients (43%) had mild aortic regurgitation on 1-year echocardiogram. In 85% of patients (n = 35), mild aortic regurgitation remained stable on the most recent echocardiogram (median, 57 ± 20 months); progression to moderate aortic regurgitation occurred in 5 patients (12%) at a median of 28 ± 18 months and remained stable thereafter; severe aortic regurgitation developed in 1 patient, eventually requiring reoperation. Five patients (5%) had moderate aortic regurgitation at 1 year, which did not progress subsequently. Two patients (2%) had more than moderate aortic regurgitation at 1 year, and both ultimately required reoperation. Although mild aortic regurgitation occurs frequently after valve-sparing aortic root replacement, it is unlikely to progress over the next 5 years and should not be interpreted as failure of the valve-preservation concept. Further, we suggest that mild aortic regurgitation should not be considered nonstructural valve dysfunction, as the 2008 valve reporting guidelines would indicate. We need 10- to 15-year follow-up to learn the long-term clinical consequences of mild aortic regurgitation early after valve-sparing aortic root replacement.

    The Genetics Society of America Medal is awarded to an individual for outstanding contributions to the field of genetics in the last 15 years. Recipients of the GSA Medal are recognized for elegant and highly meaningful contributions to modern genetics, exemplifying the ingenuity of GSA membership. The 2017 recipient is David M. Kingsley, whose work in mouse, sticklebacks, and humans has shifted paradigms about how vertebrates evolve. Kingsley first fell in love with genetics in graduate school, where he worked on receptor mediated endocytosis with Monty Krieger. In his postdoctoral training he was able to unite genetics with his first scientific love: vertebrate morphology. He joined the group of Neal Copeland and Nancy Jenkins, where he led efforts to map the classical mouse skeletal mutation short ear Convinced that experimental genetics had a unique power to reveal the inner workings of evolution, Kingsley then established the stickleback fish as an extraordinarily productive model of quantitative trait evolution in wild species. He and his colleagues revealed many important insights, including the discoveries that major morphological differences can map to key loci with large effects, that regulatory changes in essential developmental control genes have produced advantageous new traits, and that nature has selected the same genes over and over again to drive the stickleback's skeletal evolution. Recently, Kingsley's group has been using these lessons to reveal more about how our own species evolved.This is an abridged version of the interview.

  12. Work plan for the removal and subsequent management of specific waste from David Witherspoon, Inc., Knoxville, Tennessee

    International Nuclear Information System (INIS)

    1993-01-01

    The Tennessee Department of Environment and Conservation (TDEC) and the Department of Energy (DOE) have made the determination that approximately 258 drums of waste and 10 open-top boxes of waste now located at the site known as David Witherspoon, Inc., (DWI) in south Knoxville, Tennessee, should be repackaged as necessary and transferred to the K-25 Site in Oak Ridge, Tennessee, for management. This work plan addresses the four phases of activity planned and the methods of accomplishment The lint phase will consist of an assessment to determine requirements for managing the waste. Items to be investigated include site access, site conditions, personal protective equipment, waste characterization needs, packaging and labeling, transportation, receipt and storage of the waste at the K-25 Site, and site controls and monitoring required during the packaging operations to be conducted at DWI. The second phase will include mobilization of on-site support and operating facilities, sampling and transferral of a randomly selected representative fraction of the 232 drums now stored on-site in sea/land containers to storage facilities at the K-25 Site, and sampling of the waste now stored in the 26 drums inside the main process building and the 10 open-top boxes of waste stored outside and adjacent to the building. The third phase will include repackaging and transferral of the 26 drums and 10 boxes of waste to the K-25 Site and placement of the containerized waste into appropriate storage at the K-25 Site. Participants in the fourth phase of activity will demobilize the support and operating facilities from DWI, conduct an on-site evaluation at the K-25 site to verify compliance with storage and other management requirements, prepare a closeout report for the activity assessing the actions, and develop a plan for the final management method for the waste

  13. The Temple of Justice and the Key of David: Anachronism and Authority in the Chichester Seal Matrix

    Directory of Open Access Journals (Sweden)

    Lloyd De Beer

    2017-06-01

    Full Text Available In the early thirteenth century a new seal matrix was made for Chichester Cathedral. At its centre is an anachronistic architectural depiction, engraved underneath with the words “temple of justice”. The matrix’s combination of image and format is unique in English ecclesiastical seals. It is a pointed oval rather than a circle as preferred by other institutions which employed architectural images. This article is an investigation into why these distinctive choices were made. For the first time the seal matrix (in the British Museum is brought together with its counterseal drawn from extant casts and wax seals attached to charters. Doing so reveals that the Chichester seals were artistically based on a seal and counterseal made for Christ Church, Canterbury, between 1155 and 1158. I argue that the architectural image on the Canterbury seal was understood as the first “temple of justice” and that this was related to the teachings and writings of Master Vacarius and John of Salisbury, both of whom worked at Canterbury prior to the production of the seals. The context for the reinterpretation of the Canterbury seals at Chichester coincides with the appointment of Ralph Neville as bishop. Neville’s own episcopal counterseal displays a similar type of image to the cathedral’s counterseal. I suggest that Neville was responsible for commissioning the seals and that through them he promoted a relationship between himself and an Old Testament palace administrator named Eliakim, who was given the Key of David by God. This interpretation relates to Neville’s combined roles as bishop of Chichester and chancellor to the young Henry III, at whose court theocracy was a potent tract amongst the circle of archbishop Stephen Langton. A further and more general point of this article is that Neville and the artist responsible for the seals were able to borrow from the Canterbury seals because of the authority invested in architectural archetypes.

    2014-12-01

    Full Text Available This article contains the Latin text, its translation into Russian, and commentaries to the so-called “History of the Deeds of David, King of the Indies” contained in the seventh letter of the Catholic Archbishop of Acre, Jacques de Vitry, sent to the West 18th April, 1221. The “History of David” represents the most comprehensive version of the reports, which began to circulate in the Egyptian camp of the V Crusade’s participants starting from January–February 1221. These reports contained mixed description of the military campaigns of Khwarezmshah Ala ad-Din Muhammad II, Naiman khan Kuchlug, and Genghis Khan. Military operations of the last two historical figures were presented as victorious military campaign of the Christian “king David” and, therefore, of a potential ally of the Crusaders.According to Jacques de Vitry, the “History of David” was translated into Latin from the Arabic language after it had been delivered to the Prince of Antioch Bohemond IV by his spies in Muslim countries. Anticipating the text of “History”, Jacques de Vitry reports that the Sultan of al-Jazira, al-Malik al-Ashraf, was unable to send his troops against the Crusaders in connection with the appearance of an unexpected military threat on the eastern borders of his possessions. It is obvious that under this threat the Archbishop of Acre had in mind the emergence of the Mongol troops in Iraq at the end of 1220. According to Jacques de Vitry, the appearance of these reports in the Crusader camp of Damietta had a direct influence on the course of the Fifth Crusade. Crusaders in Damietta noticeably heartened after had learning of the advance of “king David” in the Middle East along with encouraging news about the impending arrival in Egypt of the Emperor Frederick II. Under the influence of these reports and after the arrival of reinforcements of the Bavarian Duke Ludwig I, the papal legate Pelagius made ​​the fateful decision to march

    Full Text Available As hastes bloqueadas além de permitirem estabilização rígida de fraturas, possuem vantagens biomecânicas quando comparadas a outras técnicas de imobilização, por atuar ao longo do eixo mecânico central do osso, além de preservar os conceitos de padrões biológicos de osteossíntese . O uso limitado de hastes bloqueadas em gatos se atribui ao fato da cavidade intramedular ser pequena, limitando o tamanho e diâmetro dos pinos. Relatam-se casos de 10 felinos que apresentavam fraturas fechadas simples ou múltiplas da diáfise femoral. Os animais pesavam entre 3,5 e 5 kg, o que permitiu a utilização de hastes de 4,0mm e 4,7mm de diâmetro. Para inserção da haste, adotou-se a via retrógrada ou a normógrada e foram realizados bloqueios com quatro parafusos de titânio de 2,0 mm de diâmetro. Complicações intra-operatórias não ocorreram, entretanto um animal sofreu fratura de colo femoral e fratura transversa distal ao implante, três dias após o ato cirúrgico, devido a novo trauma. Os animais foram submetidos a exames radiográficos até quatro meses após a intervenção, evidenciando-se formação de calo ósseo secundário e consolidação óssea em período de 61-89 dias. Clinicamente, ocorreu esporadicamente alteração na marcha por leve claudicação de apoio definida por escala de claudicação, entretanto os animais iniciaram o apoio adequado entre três e oito dias após o ato operatório. Complicações pósoperatórias ocorreram referentes ao animal que sofreu novo trauma, entretanto notou-se consolidação do foco primário tratado pelo implante com 61 dias e consolidação da nova fratura num período total de 150 dias do início do tratamento conservativo por penso esparadrapado e tala. Conclui-se que o uso de haste bloqueada em felinos foi adequado uma vez que houve consolidação óssea em todos os casos, com retorno precoce da função do membro, permitindo a deambulação.Interlocking nails allow rigid

    Recent scholarship has frequently emphasized modern states' use of social science to impose universalized conceptions of rationality and order upon diverse, highly localized settings. The New Deal era experiences of William M. Leiserson and David J. Saposs, however, provide an analytical alternative. As students of the pioneering labor economist John R. Commons, Leiserson and Saposs sought to create mechanisms for state oversight of industrial labor relations that recognized local practices and arrangements. Although their approach failed to take hold within the National Labor Relations Board, localized institutional and political contingencies, and not a hegemonic modernism, account best for their frustrated aspirations in the late 1930s. © 2010 Wiley Periodicals, Inc.

    This paper explores the relationship of astronomical phenomena and the painted ceiling The Glorious Deeds of Swedish Kings executed around 1694-1696 by the Swedish court painter David Klöcker Ehrenstrahl in the Royal manor Drottningholm, outside Stockholm. The central theme of the painting is how "Reputation" brings the renown of the valour of the Swedish kings to the stars. When Galileo dedicated the moons of Jupiter to the Medici's he used an already established tradition of likening prominent people to celestial phenomena. This paper explores why motifs related to the stars and heavens was considered to be so suitable in the court context in early modern Europe.

La réécriture satirique de Heym de l'histoire biblique se concentre sur le personnage d’Ethan, un écrivain-historien nommé par le roi Salomon pour composer un rapport officiel sur la vie et l’arrivée au pouvoir du roi David. À un moment donné les deux fils d’Ethan, Sem et Sheleph, reviennent du marché et racontent à Ethan certaines rumeurs «savoureuses» qu'ils y ont entendues. Ces rumeurs, tandis qu’elles sont un peu exagérées et embellies, fournissent toutefois des aperçus de la situation politique qui sont beaucoup plus fidèles à la vérité que les inventions des porte-parole officiels.

In The King David Report (1972, Stefan Heym (1913-2001 offers a favorable view of gossip, notwithstanding biblical censuring of that activity (e.g. Proverb 11:13. Heym's satirical re-telling of the biblical story focuses on the character of Ethan, a writer-historian appointed by King Solomon to compose an official report on the life and rise to power of King David. At one point Ethan's two sons, Shem and Sheleph, come back from the market, telling Ethan of some "juicy" rumors they heard there. These rumors, while using some exaggerations and added embellishments, nevertheless provide insights into the political situation much more faithful to the truth than the fabrications of official spokespersons. To substantiate Heym's literary portrayal of gossip as a channel for communicating subversive truth in authoritarian regimes, I cite Robert Darnton

    Full Text Available This article discusses Michael Berkeley’s opera Jane Eyre. Premiered on June 30, 2000 by Music Theatre Wales at the Cheltenham International Festival of Music, this opera is based on the novel by Charlotte Brontë and the libretto is written by the Australian poet, novelist, playwright and librettist, David Malouf. It was risky and daring to try to adapt this famous and long novel for the stage. We will particularly focus on the similarities and differences between the novel and the opera as well as on the strategies used both by David Malouf and Michael Berkeley to adapt it. Through the analysis of the similarities we will see how Michael Berkeley set to music some of the great themes and elements of the novel: passion, a sense of entrapment, the “Gothic” atmosphere. On the other hand, the analysis of the discrepancies between the novel and the opera as they appear in both the libretto and the music will lead us to a modern apprehension of the characterization of madness as well as of the metafictional dimension of the rewriting of Jane Eyre by David Malouf and Michael Berkeley.

    Full Text Available O objetivo deste artigo é fundamentar a escolha pela perspectiva teórica do materialismo histórico-geográfico, desenvolvida pelo geógrafo David Harvey para compreender uma região. Para tanto, apresentamos e discutimos também os referenciais predominantes nas análises sobre regiões, com o intuito de demonstrar os limites desses referenciais e as possibilidades abertas pela perspectiva de Harvey. Assim, apresentamos alguns dos principais conceitos que têm orientado as ações de governos dos mais diversos matizes; a abordagem de David Harvey bem como seus pressupostos teóricos e históricos; e uma análise comparativa em que demonstramos as limitações dos referenciais predominantes e as possibilidades da perspectiva do último autor. Ao final, conclui-se que o materialismo histórico-geográfico permite compreender que as dinâmicas sociais e econômicas de uma região se caracterizam em processos conflituosos e contraditórios e resultam em uma configuração regional específica e transitória.

    Full Text Available The eminent philosopher of biology, David Hull has proposed that a "general theory of evolution" can be advanced that would account for the evolution of organisms as well as for the evolution of scientific knowledge. According to Hull, competition among scientists plays in conceptual evolution a similar essential role as competition among organisms plays in biological evolution. Hull uses the sociobiology tradition to explain the apparently altruistic behavior of scientists in the search for knowledge.

Os tratamentos principais foram constituídos pelas alturas da pastagem de inverno (aveia + azevém: 0,10; 0,20; 0,30 e 0,40 m e sem pastejo, obtidas variando-se a carga animal, e os tratamentos secundários foram duas profundidades de atuação da haste sulcadora de adubo: 0,12 e 0,15 m. A massa seca de raízes da pastagem, na camada de 0 a 0,12 m, aumentou com o incremento na intensidade de pastejo. Analisando os valores de resistência mecânica do solo à penetração, o efeito do pastejo foi detectado até 0,12 m, sendo crescentes com a intensidade de pastejo. A força de tração demandada pelas hastes aumentou de 1.900 para 4.300 N (120%, quando a profundidade de trabalho passou de 0,12 para 0,15 m. O esforço de tração nas hastes sulcadoras também foi maior quanto maior a carga de animais sobre a pastagem, embora as diferenças tenham sido significativas apenas entre os tratamentos sem pastejo e os mantidos a alturas de 0,10 e 0,20 m.

  5. The Liberating Role of Astronomy in an Old Farmer's Almanac: David Rittenhouse's "Useful Knowledge" and a Benjamin Banneker Almanac for 1792

    Walker, Theodore, Jr.

    2012-06-01

    Traditionally, astronomy met theology and political ethics in almanacs. As presented in early New England almanacs of the farmer's type, astronomy was deity-affirming and liberty-oriented. The old English label for astronomy that affirms theology was "Astro-theology" (William Derham, 1715). The New England rendering of astro-theology was so strongly oriented towards liberty that it can now be labeled astro-liberation theology. This 21st century label is appropriate because 18th century New England printers and astronomers used astronomy to demonstrate the glory of the Creator (astro-theology) and to encourage liberation from colonialism and slavery (astro-liberation theology). A philosophy of astronomy as "useful knowledge' expressed by David Rittenhouse in 1775 - and implicit in a Benjamin Banneker almanac for 1792 - included liberty-oriented visions of planet Earth as seen from outer space, and liberty-oriented visions of intelligent life on other planets orbiting other stars.

    The Keeling curve has become a chemical landmark, whereas the papers by Charles David Keeling about the underlying carbon dioxide measurements are not cited as often as can be expected against the backdrop of his final approval. In this bibliometric study, we analyze Keeling's papers as a case study for under-citedness of climate change publications. Three possible reasons for the under-citedness of Keeling's papers are discussed: (1) The discourse on global cooling at the starting time of Keeling's measurement program, (2) the underestimation of what is often seen as "routine science", and (3) the amount of implicit/informal citations at the expense of explicit/formal (reference-based) citations. Those reasons may have contributed more or less to the slow reception and the under-citedness of Keeling's seminal works.

    Full Text Available Contemporary Scottish playwright David Greig’s dramaturgy has been concerned with the massive changes wrought across the world by neoliberal globalization in the last two decades. A political triple turn comprising ethics, the media and the spectator, and a shift between the notion “‘mediatized’ reiterative ‘expectator’” to “mediated performing spectator” within the “polethic” frame of ‘relationality’ in Greig’s works are argued in this article. It is further argued that the plays examined (Damascus, The American Pilot, Brewers Fayre and Fragile use productive strategies like diffusion, reversibility and interchangeability, which foreground the asymmetries of the global/technologized age “polethically” mediating the global performing spectator.

    2011-01-01

    This article examines the career of pioneer British psychoanalyst David Eder (1865–1936). Credited by Freud as the first practising psychoanalyst in England, active in early British socialism and then a significant figure in Zionism in post-war Palestine, and in between an adventurer in South America, a pioneer in the field of school medicine, and a writer on shell-shock, Eder is a strangely neglected figure in existing historiography. The connections between his interest in medicine, psychoanalysis, socialism and Zionism are also explored. In doing so, this article contributes to our developing understanding of the psychoanalytic culture of early twentieth-century Britain, pointing to its shifting relationship to broader ideology and the practical social and political challenges of the period. The article also reflects on the challenges for both Eder’s contemporaries and his biographers in making sense of such a life. PMID:23752865

    Full Text Available More than a century after the Emancipation Proclamation, in a society that still others blackness, we continue to hold to the mythical humanizing power of literacy. In our own time this has been poignantly evinced in the public reception of the current President of the United States, Barack Obama. He has been internationally hailed for his written and oral eloquence, and many Americans expected that Obama’s evident intellectual prowess would reverse prevailing stereotypes of black inferiority. Obama’s rhetorical success is rooted in the longstanding literary practice of invoking the mythical founding fathers to validate text and subject. In this regard, David Walker’s Appeal (1829 represents the emergence of a long tradition of black voices invoking America’s most sacred patriarchs and their rhetoric of Americanness.

  13. Connla's well: An exploration of similar elements of ancient Celtic perspectives and David Bohm's theories in quantum physics from a Jungian perspective

    Science.gov (United States)

    Maciel, Duan

    This dissertation addresses the common elements between ancient Celtic mystical doctrines and philosophy and David Bohm's unique theories in quantum physics through a Jungian lens, using research based in dialogical hermeneutics. The premise of this dissertation is that psi, or the probability wave function of quantum physics, and its world of potentia are the same entities as Jung's objective psyche (or collective unconscious) and its domain, the unus mundus. In addition, the study explores the remarkable similarity between the ancient Celts' Otherworld, quantum physics' world of potentia, and Jung's unus mundus. These similarities argue for an in-depth Jungian analysis of this important but largely neglected mythology. The study explores the supposition, based partially on physicist David Bohm's theories of the implicate and explicate orders, that the above world of potentia intertwines with our three-dimensional world in a reciprocal creativity, designed to enhance both worlds. The study further advocates a greater emphasis on the creative arts therapies in the therapeutic situation, based on the above reciprocity. It is argued that this emphasis on creativity in the temenos may activate a profound "quantum leap" of insight in the analysand, most likely due to the reciprocity in which the objective psyche responds uniquely to the particular and individual creativity offered in order to heal the personal psyche. As we creatively access the objective psyche, that entity responds in kind, giving us new understanding and allowing us to change our attitudes and to further individuation, which in turn enhances the objective psyche. In addition, a psyche of reality is postulated in which Jung's concept of the objective psyche is expanded from the collective unconscious of humankind to a collective unconscious of All That Is, reflecting the findings in quantum physics that our universe is self-aware, organic, and holistic rather than mechanical and fragmented.

    Although implicitly accepted by many that the durability of valve-sparing aortic root replacement in patients with bicuspid aortic valve disease and connective tissue disorders will be inferior, this hypothesis has not been rigorously investigated. From 1993 to 2009, 233 patients (27% bicuspid aortic valve, 40% Marfan syndrome) underwent Tirone David valve-sparing aortic root replacement. Follow-up averaged 4.7 ± 3.3 years (1102 patient-years). Freedom from adverse outcomes was determined using log-rank calculations. Survival at 5 and 10 years was 98.7% ± 0.7% and 93.5% ± 5.1%, respectively. Freedom from reoperation (all causes) on the aortic root was 92.2% ± 3.6% at 10 years; 3 reoperations were aortic valve replacement owing to structural valve deterioration. Freedom from structural valve deterioration at 10 years was 96.1% ± 2.1%. No significant differences were found in survival (P = .805, P = .793, respectively), reoperation (P = .179, P = .973, respectively), structural valve deterioration (P = .639, P = .982, respectively), or any other functional or clinical endpoints when patients were stratified by valve type (tricuspid aortic valve vs bicuspid aortic valve) or associated connective tissue disorder. At the latest echocardiographic follow-up (95% complete), 202 patients (94.8%) had none or trace aortic regurgitation, 10 (4.7%) mild, 0 had moderate to severe, and 1 (0.5%) had severe aortic regurgitation. Freedom from greater than 2+ aortic regurgitation at 10 years was 95.3% ± 2.5%. Six patients sustained acute type B aortic dissection (freedom at 10 years, 90.4% ± 5.0%). Tirone David reimplantation valve-sparing aortic root replacement in carefully selected young patients was associated with excellent clinical and echocardiographic outcome in patients with either a tricuspid aortic valve or bicuspid aortic valve. No demonstrable adverse influence was found for Marfan syndrome or connective tissue disorder on durability, clinical outcome

    Full Text Available Os Diálogos sobre a Religião Naturalestão, certamente, entre as obras mais conhecidas de David Hume. Dividido em doze partes, o texto examina, por meio de um diálogo entre o místico Demea, o deísta Cleantes e o cético Filo, diversos argumentos acerca da existência e da suposta natureza da divindade. Trata-se de publicação que gerou enorme controvérsia. Hume afirma, em carta de 10 de março de 1751 a Sir Gilbert Elliot, que faz de Cleantes “o herói” da história. Ainda, em outra correspondência, remetida em 8 de junho de 1776 a William Strahan, seu editor, Hume pretende convencê-lo a publicar os Diálogos, não sem apresentar a ressalva de que, ainda que o cético seja silenciado ao final, a obra apresenta, antes disso, tópicos que poderiam gerar comoção.

The study involved 64 children admitted in the wards of "undernutrition" and "general". Detection of intestinal parasites in faecal samples was assessed by fresh examination stained with Lugol, as used at the HPDBL. The evaluation of nutritional status of children in HPDBL included clinical, biochemical and anthropometric parameters. Out of the 64 children analyzed, six (9.3% were infected with Giardia lamblia (6.3%, Ascaris lumbricoides (1.6% and Hymenolepis diminuta (1.6%. These cases of parasitism were more common in children over three years and hospitalized in the general ward. Regarding nutritional status, the majority (56.3% had some kind of nutritional deficiency (body weight below 70%, oedema in both legs, severe thinness, which were more frequent in females (55.6% and in children under 24 months (77.7%. About 92.2% of children admitted were from suburban areas of Luanda presenting greater vulnerability to parasitic infections and other diseases owing to households conditions, with a majority without piped water. However, no evidence has been encountered in this population sample of an association between intestinal parasites and malnutrition throughout the present study.

  2. Qual a origem de nossas ideias? O processo cognitivo de associação de ideias segundo a metodologia empirista de David Hume

    2015-05-01

    Full Text Available O presente trabalho aborda o processo de conhecimento da natureza humana, mais especificamente o processo mental de associação de ideias, tendo como referência a metodologia empirista proposta por David Hume. Com base nessa metodologia, indaga-se como a investigação filosófico-científica pode explicar a origem das ideias e o seu processo associativo: como, afinal, a mente humana processa suas ideias? Para responder a indagação, pretende-se analisar a abordagem descritiva do empirismo proposto por Hume, com o objetivo de auferir as percepções da natureza humana a partir da distinção entre impressões e ideias. As impressões sensíveis desempenham um importante papel na formação das ideias, pois são percepções mais vinculadas a elementos empíricos e, em razão disso, mais fortes, vívidas e intensas, ao ponto de impulsionar o processo associativo de ideias na natureza humana. Toda ideia deriva sempre de uma impressão – eis o célebre princípio do empirismo que ainda hoje continua a servir de base para as ciências empíricas.

  3. In response to David Greenwood's `Place mobility and faculty life: mindfulness through change' through the lens of science teacher education programs

    In writing this review, I draw on the experience of David Greenwood (Cult Stud Sci Educ 10:5-16, 2015) whose ethnographic study sheds light on his growth as a faculty member who has taught in various settings that are quite different from the culture that he grew up with. I extend his thoughts on ecological mindfulness to encompass a culturally aware method of teaching based on place sensitized more to the needs of science teacher preparation programs. The methods used in writing the review included literature searches for articles that incorporate ecological mindfulness and culturally responsive teaching in science teacher preparation programs and reflected ideas voiced in Greenwood's article. Although he seems that he is primarily addressing other faculty members, his experiences can be used as lifelong lessons for preservice teachers entering a primarily homogeneous workforce expected to teach an increasingly diverse student population. His humor, use of Haiku, poetry and mindfulness as a way of becoming one with a culture that he is not accustomed has many lessons that prove useful in training more culturally responsive teachers. In light of an increasingly diverse US student population versus a stagnantly homogeneous teaching workforce, his reflective practice will prove useful to teachers who are expected to teach students with cultures different from their own.

    Full Text Available O processo de aprendizagem tem motivado, desde a Antigüidade, intensos debates. Dentre as diferentes teorias propostas tem ganho relevância, nos séculos XX e XXI, a concepção cognitivista de David Ausubel, na qual se assume que os mecanismos do aprender são mais eficientes em situações nas quais o estudante consegue, utilizando conhecimentos prévios, agregar e incorporar significado aos novos conteúdos, evitando-se, assim, que esse conhecimento recém-incorporado seja armazenado, por meio de associações ineptas, à estrutura cognitiva. No âmbito da educação médica, diante das imperiosas mudanças necessárias para a formação de um profissional que aprenda a aprender, a aprendizagem significativa permite uma genuína contextualização dos conhecimentos necessários à prática médica, facultando, portanto, um aprendizado mais efetivo e permitindo a atuação em um contexto complexo e interdisciplinar. Em conformidade com o exposto, o presente manuscrito objetiva apresentar a teoria da aprendizagem significativa, discutindo elementos da incorporação deste conceito à educação médica.

    Full Text Available The Tempest (1611 is one of those Shakespearean texts which have been adopted and adapted most frequently. This article explores two early Nineties appropriations of the Bard’s romance, that is David Greig’s unpublished monologue A Savage Reminiscence or (How to Snare the Nimble Marmoset, first performed in 1991, and Liz Lochhead’s The Magic Island, a rewriting of The Tempest for seven- to eleven-year-olds, first staged in 1993. Even if they differ from a variety of points of view, both Scottish Tempests retell the Shakespearean narrative through the lens of memory. In Greig’s appropriation, after being left alone on the island, a guilty Caliban recollects some past events – in particular his rape of Miranda – from his own marginalised perspective. Similarly, Lochhead’s The Magic Island, which adapts Shakespeare’s play to the needs and taste of a young audience by focusing on the theme of friendship, reconstructs the story retrospectively through the eyes of Prospero’s daughter. Through a web of intertextual references interwoven with contemporary echoes, Greig and Lochhead re-member and dismember their source problematizing any unimaginative subscription to the Shakespearean canon.

    Full Text Available In the modern era, discerning TV viewers know the shows that trade in cheap laughs by making fun of people with disabilities are not tapping into much creativity. So it was a surprise in 2008 when the highly regarded comedy show Saturday Night Live (SNL stooped to that level by ridiculing the blind governor of New York, David Paterson, in a series of sketches lasting two years. This article analyzes the way humor narratives about a high-profile blind politician on television, like those depicted in the SNL skits, may have influenced larger cultural themes about blindness. Because the East Coast news media reported on the SNL skits every time an episode aired, this project undertook a textual analysis of all aspects of the controversy including the content of the SNL skits, the repeated responses from Gov. Paterson and the blindness community, and the news media framing of the SNL-Paterson skit story. This analysis examines the intertextuality of the event, revealing that the blindness community had a very different reading of the SNL skits, due to concerns about continuing media narratives that devalue and stereotype them.   Keywords: blindness, disability humor, TV comedy shows, skit comedy, politicians

    To highlight the contributions from the University of Chicago under the leadership of Dr David B. Skinner to the understanding of gastroesophageal reflux disease (GERD) and its complications. The invention of the esophagoscope confirmed that GERD was a premorbid condition. The medical world was divided between those who believed in a morphological lower esophageal sphincter (LES) and those who did not. Those who did not believe attempted to rearrange the anatomy of the foregut organs to stop reflux with minimal success. The discovery of the LES focused attention on the sphincter as the main deterrent to reflux and the hope that measurement of a low LES pressure would mark the presence of GERD. This turned out not to be so. In July 1973, with this history of confusion, Dr Skinner at the age of 36 assumed the chair of surgery at the University of Chicago. The publications of the University of Chicago's esophageal group were collected from private and public (PubMed) databases, reviewed, and seminal contributions selected. Twenty-four-hour esophageal pH monitoring led to the understanding of the LES, its contribution to GERD, and the complication of Barrett's esophagus. The relationship of Barrett's to adenocarcinoma was clarified. The rising incidence of esophageal adenocarcinoma led to contributions in the staging of esophageal cancer and its treatment with an en bloc resection. Ten years after the death of Dr Skinner, we can appreciate the monumental contributions to benign and malignant esophageal disease under his leadership.

The aim of this paper is to analyse Lodge’s recent turn to life narratives and, in particular, his autobiographical story of 2015; and, consequently, to address the following questions: Does Lodge’s memoir offer “an experiment in autobiography” (to quote H.G. Wells, one of Lodge’s favourites, or remain a conventional life story immune to the tenets of contemporary life writing? Is it the work of a (self- historian, or a novelist? Does it belong to the “regime of truth,” or is it the product of memory? Finally, is it, indeed, a memoir (as its subtitle claims, or a specimen of self-biography? The paper will show special interest in the work’s generic characteristics and will offer an attempt to locate Quite a Good Time to Be Born on the map of contemporary life writing practices.

    In valve-sparing aortic root replacement (VSARR), how to reproduce Valsalva sinus has been an issue. In the original David V procedure, they put plication stitches at sinotubular junction level, although the reefing effect is limited and distal graft remains larger than native. Other modified techniques are two-grafts technique and ready-made Valsalva graft. However, the former needs graft-graft anastomosis and may not be cost-effective, while in the latter, the shape of sinus is fixed and minor adjustment is difficult. David V University of Tokyo modification (David V-UT) is our original solution to that, creating pseudosinus with one straight graft by longitudinal size-reduction running sutures above each pseudosinus. The purpose of the present study is to investigate long-term outcome of David V-UT. We analyzed 59 David V-UT patients from February 2004 to February 2013 and long-term outcomes were investigated by Kaplan-Meier methods. Risk factors for adverse events "death or recurrent aortic insufficiency (AI) with or without aortic valve reoperation" were analyzed by using Cox proportional hazard models. Mean age was 33.1±14.5 years, and 38 patients (64%) were male. Marfan syndrome (MFS) accounts for 47 patients (80%). Only one patient was with bicuspid aortic valve. No in-hospital mortality was observed. Mean follow-up was 4.9±2.4 years. Estimated survival was 94.0±3.4% at 5 years. Freedoms from aortic valve reoperation and recurrent AI greater than mild were 95.7±3.0% and 88.9±4.7% at 5 years, respectively. In Cox proportional hazard analysis, preoperative AI greater than mild and Z score of annular diameter were significant risks for adverse events (p=0.027 and 0.045, hazard ratio 6.084 and 1.432, 95% C.I. 1.225-30.21 and 1.008-2.035, respectively). Even in Marfan-characterized population, David V-UT provided satisfactory long-term outcome, comparable to other VSARR modifications. It is simple but can freely reproduce trilobed sinus with one straight

    Full Text Available A semeadura direta é um sistema de manejo eficiente em termos de conservação do solo e da água, economia de energia e capacidade operacional dos conjuntos mecanizados. No entanto, em áreas onde existem pecuária e produção de grãos, ou onde o solo é trafegado e trabalhado em condições inadequadas, pode ocorrer compactação do solo nas camadas superficiais. Mesmo compactadas, essas camadas não necessitariam ser descompactadas ou revolvidas, se boa germinação e desenvolvimento da cultura fossem alcançados apenas com a mobilização efetuada pelos sulcadores da semeadora. Os objetivos deste estudo foram determinar a força de tração demandada e o volume de solo mobilizado pelas hastes sulcadoras de adubo, além da patinagem do trator, em diferentes estados de consistência de um Argissolo, em semeadura direta sobre campo nativo dessecado. Houve aumento na demanda de tração com o aumento da profundidade de atuação da haste, e sua magnitude dependeu do estado de consistência do solo. O aumento da velocidade não influenciou na força de tração na haste em solos seco e úmido, porém, na condição de friabilidade, essa foi maior. O volume de solo mobilizado pelo sulcador foi maior em solo seco e a 12 cm de profundidade. Nos estados de consistência seco e friável e na maior profundidade testada, verificou-se a necessidade de acionamento da TDA do trator para obtenção de níveis aceitáveis de patinagem.Direct drilling or no tillage systems are among the most successful agricultural alternatives regarding soil and water conservation, energy economy and operational capacity of machinery. Some areas where cattle raising and grain production share the same grounds, or where soils are trafficked in moist conditions they may show compaction of the upper layers. Compacted soil areas may not need to be chiseled or plowed, if seed germination and good growing standards are reached by the initial soil conditioning solely by planter

    The Chemical Analysis Automation (CAA) project is developing standardized, software-driven, site-deployable robotic laboratory systems with the objective of lowering the per-sample analysis cost, decreasing sample turnaround time, and minimizing human exposure to hazardous and radioactive materials associated with DOE remediation projects. The first integrated system developed by the CAA project is designed to determine polychlorinated biphenyls (PCB) content in soil matrices. A demonstration and development testing of this system was conducted in conjuction with surface soil characterization activities at the David Witherspoon 1630 Site in Knoxville, Tennessee. The PCB system consists of five hardware standard laboratory modules (SLMs), one software SLM, the task sequence controller (TSC), and the human-computer interface (HCI). Four of the hardware SLMs included a four-channel Soxhlet extractor, a high-volume concentrator, a column cleanup, and a gas chromatograph. These SLMs performed the sample preparation and measurement steps within the total analysis protocol. The fifth hardware module was a robot that transports samples between the SLMs and the required consumable supplies to the SLMs. The software SLM is an automated data interpretation module that receives raw data from the gas chromatograph SLM and analyzes the data to yield the analyte information. The TSC is a software system that provides the scheduling, management of system resources, and the coordination of all SLM activities. The HCI is a graphical user interface that presents the automated laboratory to the analyst in terms of the analytical procedures and methods. Human control of the automated laboratory is accomplished via the HCI. Sample information required for processing by the automated laboratory is entered through the HCI. Information related to the sample and the system status is presented to the analyst via graphical icons

    2017-11-01

    Original ideas and innovation cannot always be ordered like a courier service and delivered fresh to our desk at 9 am. Yet, most creativity-based organizations, careers, and professions, science and biotechnology innovation included, emphasize the speed as the prevailing ideology. But a narrow focus on speed has several and overlooked shortcomings. For example, it does not offer the opportunity to draw from, and stitch together disparate concepts and practices for truly disruptive innovation. Preventing false starts, learning from others' or our own mistakes, and customizing innovations for local community needs are difficult in a speed-hungry innovation ecosystem. We introduce a new strategy, the Fast-Second Winner, specifically in relation to global development of biotechnologies and precision medicine. This à la carte global development strategy envisions a midstream entry into the innovation ecosystem. Moreover, we draw from the works of the late David Bowie who defied rigid classifications as an artist and prolific innovator, and introduce the concept and practice of slow innovation that bodes well with the Fast-Second Winner strategy. A type of slow innovation, the Fast-Second Winner is actually fast and sustainable in the long term, and efficient by reducing false starts in new precision medicine application contexts and geographies, learning from other innovators' failures, and shaping innovations for the local community needs. The establishment of Centers for Fast-Second Innovation (CFSIs), and their funding, for example, by crowdfunding and other innovative mechanisms, could be timely for omics and precision medicine global development. If precision medicine is about tailoring drug treatments and various health interventions to individuals, we suggest to start from tailoring new ideas, and focus not only on how much we innovate but also what and how we innovate. In principle, the Fast-Second Winner can be applied to omics and other biotechnology

    Full Text Available Many centuries before Joseph Conrad’s Heart of Darkness (1902 and Rudyard Kipling’s Kim (1901 were published, the East and West were still divided, as in Tacito’s De Germania, by a limes also visible in David Malouf’s An Imaginary Life (1978, in which the poet Ovid exiled at Tomi, is friends with the savage Child, of animal nature in a human body, similar to the metamorphic migrants of Salman Rushdie’s The Satanic Verses (1988, which hides the magnificent and ancient East of Mahābhārata and Rāmāyana in many Western identities, lost in diabolic European cities. This chaotic antithesis in Michael Ondaatje’s pages lets Sri Lanka’s childish ghosts float amidst stories of peregrination and in search of a Promised Land. In the Skin of a Lion (1987 includes an epigraph from the ancient poem of Gilgamesh, an Eastern echo in a novel profoundly important for many Western studies that often focus on the theory of the canon or on postmodern literature. These categories are discussed with the prospect of broadening cultural and post-colonial studies, in order to merge theory of genres and thematic criticism with anthropology, mythology, and ethnology. Multiple citations expand the original object of research, adding the colonial prophecy present in North American myths, as demonstrated by Margaret Atwood, Margaret Laurence or Lévi-Strauss. Incessantly moving from one space to another, authors give voice to the native cry from multiple perspectives, narrating – like all colonial empires founded on human cruelty– the beast’s nature that has shown its worst aspect.

  18. Imagining Exodus for Israel-Palestine: Reading the Secular and the Sacred, Diaspora and Homeland, in Edward Said and David Grossman

    Directory of Open Access Journals (Sweden)

    Anna Hartnell

    2005-03-01

    Full Text Available This paper takes as its starting point Edward Said's distinction between 'religious' and 'secular' modes of cultural affiliation. As these simultaneously diverging and converging modes also trammel the particular grounds of thinking that have been Said's natural target of criticism - Zionism - his work speaks particularly powerfully to the debate surrounding the religious genealogy of Jewish identity. This paper argues that Said's interventions on Zionism highlight as problematic the position whereby the 'Ingathering of the Exiles' is promoted as coexisting with a 'diasporic consciousness' nurtured by Judaism during exile; messianic hopes of religious Jews cannot be reconciled with physical return to the Promised Land; identity circumscribed by ethnicity and place cannot stand in as exemplary for the exiled, unsettled and ultimately homeless identity trumpeted by discourses of the 'post', as many contemporary theorists would have it. And yet through an exploration of the writings of David Grossman, whose construction of Jewish identity is envisaged through the regulating, competing and collaborating tropes of Zionism and Diaspora, I argue that this position is crucial for the elaboration of Israeli identity. I also argue that in fact there is room within Said's thinking both for the anti-essentialist elaboration of 'homeless' identities as well as 'the permission to narrate' an identity politics, and that his own distinction between the 'secular' and the 'religious' begins to disassemble. I explore this blurring of the sacred and the secular through the prism of Exodus - as both concept and narrative. This paper suggests that it is precisely Said's achievement to embody these tensions between religion and its other, divine providence and human agency, historical materialism and postmodernism, alienation and its perennially tempting opposite: home.

  2. The vision of David Marr.

    Science.gov (United States)

    Stevens, Kent A

    2012-01-01

    Marr proposed a computational paradigm for studying the visual system, wherein aspects of vision would be amenable to study with what might be regarded a computational-reductionist approach. First, vision would be cleaved into separable 'computational theories', in which the visual system is characterized in terms of its computational goals and the strategies by which they are carried out. Each such computational theory could then be investigated in increasingly concrete terms, from symbols and measurements, to representations and algorithms, to processes and neural implementations. This paradigm rests on some general expectations of a symbolic information processing system, including his stated principles of explicit naming, modular design, least commitment, and graceful degradation. In retrospect, the computational framework also tacitly rests on additional assumptions about the nature of biological information processing: (1) separability of computational strategies, (2) separability of representations, (3) a pipeline nature of information processing, and that (4) the representations employ primitives of low dimensionality. These assumptions are discussed in this retrospective.

    My interest in science started very early, probably with science-fiction books like the Tom Swift series, which are aimed at children. After brief stints in chemistry and engineering, I chose to study physics at Boston University because I found it the most challenging. I also had dreams of being an "inventor" and thought physics would give me an understanding of how things worked.

  15. De David Belasco à Giacomo Puccini : La Fanciulla del West, premier opéra « américain » From David Belasco to Giacomo Puccini:La Fanciulla del West, first “American” opera

    Walter Zidaric

    2009-10-01

    Full Text Available La Fanciulla del West is a “horse opera” resulting from the second collaboration between David Belasco and Giacomo Puccini. This work, specially composed for the American stage, which had its world premiere at New York’s Metropolitan Opera in December 1910, paved the way for American composers who increasingly focused on American History in their quest for a “national” opera. For the first time, Puccini resorted to genuine Indian music, a Zuni melody, which he re-elaborated for dramatic purposes and associated with the nostalgic mood of uprooted people, the miners who left their home country for America. The Other – the native American viewed from the vantage point of the white, as well as the foreigner – no longer represented a threat, as had been the case in the operatic repertoire before, but became part and parcel of a multicultural society, like the Italian immigrant to whom Puccini also paid tribute. The Zuni melody, which opens and closes the opera, contributes to giving a genuine twist to a score which is the first one to tackle the foundations of the American nation.

    2011-09-01

    Full Text Available L’article prend comme point de départ les travaux de Zachary Baqué et vise à montrer, à travers une étude diachronique, que les films hollywoodiens de Lynch ne le sont pas uniquement par leur représentation satirique d’un système corrompu qui compromet les ambitions qu’il suscite, ni même par la façon dont il retravaille les conventions génériques et narratives propres au cinéma hollywoodien. Hollywood est une présence à la fois horizontale et verticale, physique et abstraite, réelle et imaginaire, qui renvoie à la ville, au système, au cinéma et au rêve, si bien que la satire, la topographie, les motifs visuels parfois clichés et les références filmiques sont intimement liés en une expression de la subjectivité et de l’intérioritéThe article takes Zachary Baqué’s study of Los Angeles in the films of David Lynch as a starting point to explore David Lynch’s Hollywood movies. The author contends that the films offer more than a satirical representation of a corrupt, unhealthy system which threatens dreams and artistic creativity, or a parodic play on Hollywood genre and narrative conventions. Rather, Hollywood is a character, a presence, revealed as both horizontal and vertical, physical and abstract, evoking the city, the studio system, cinema and dreams, so that the satire, the visual motifs and clichés and the topography of Hollywood, and the references to Hollywood films, constitute a complex fabric of subjectivity and interiority.

Entre os principais resultados da assistência, destacam-se a taxa de transferência materna com 11,4%; a taxa de cesárea com 2,2%; a taxa de admissão em Centro de Tratamento Intensivo (CTI neonatal de 1,2%; e a taxa de Apgar This was a descriptive and retrospective study of 2,117 deliveries from January 2002 to July 2003 at the Dr. David Capistrano da Costa Filho Birthing Center in Belo Horizonte, Minas Gerais, Brazil. Widespread questions have been raised concerning the quality of services provided at birthing centers by obstetric nurses. The results of the current study were: 11.4% maternal transfer rate; 2.2% cesarean sections; 1.2% neonatal ICU admissions; and 1% 5-minute Apgar scores below 7. Delivery dystocia and the request for epidural anesthesia were the main reasons for maternal transfer, and respiratory distress was the main cause of neonatal ICU admission. Corrected neonatal mortality was 2 per 1,000 live births. The results at this birthing center did not differ significantly from those in a review of the international literature. The most striking finding was the low cesarean rate. Comparative studies and more comprehensive national data on low-risk gestations are needed.

    2017-12-01

    Full Text Available There is one type of biography that maintains an ambiguity with regard to what is true and what is not, being based solely on fiction or a mixture of documented and invented information. Such a form has been used in literature for more than a century, but became especially popular with the rise of postmodernism. With its help it is easier to notice the problematic traits of a traditionally impersonal biography and at the same time reflect on the identity of literary discourse. We are thus going to examine two works, published in the last two decades, which can be considered as examples of such literary production. The first is Roberto Bolaño’s La literatura nazi en América (Nazi Literature in the Americas, published in 1996, and based on imaginary facts set in a historically realistic context. The second one, published in 2012, is Davide Orecchio’s Città distrutte: sei biografie infedeli, which depicts with fictional biographies the lives of real people and actual historical events (among others, fascism in Italy and dictatorship in Argentina. The analysis reveals some specific strategies and possible aims and, in particular, points out that behind various ingenious narrative choices (capable of misleading the reader with their parody of traditional biographical discourse there is a radical reference to historical consciousness.

    1997-01-01

    Full Text Available Aneurismas da aorta ascendente (AAA e dissecções agudas da aorta (DAA são defeitos que cursam com insuficiência valvar aórtica (IAo na maioria dos pacientes, geralmente causada por vários mecanismos. Em 30% a 50% dos casos, os folhetos aórticos são morfologicamente normais, possibilitando a reconstrução através do reimplante da valva e das artérias coronárias em um tubo corrugado de Dacron e pericárdio bovino. Descrita por Tirone David, esta técnica evita a prótese valvular e, provavelmente, nos casos de AAA, corrige definitivamente os mecanismos envolvidos. No período de novembro de 1994 a dezembro de 1995 operamos 11 pacientes, que foram assim divididos: Grupo I: DAA, 5 pacientes, todos com o Tipo 1 de DeBakey, sendo 4 agudos e 1 crônico; Grupo II: AAA, 6 pacientes, a maioria com idade acima de 50 anos. No Grupo I empregamos hipotermia profunda, parada circulatória total e perfusão cerebral retrógrada. No Grupo II usamos hipotermia moderada a 28oC. Em ambos a proteção miocárdica foi realizada através de infusão anterógrada intermitente e isotérmica de solução cardioplégica sangüínea associada a solução salina gelada no pericárdio. Dois (18,2% pacientes faleceram na fase hospitalar e 1 (9% tardiamente, todos do Grupo I, e 8 vêm sendo acompanhados, com tempo máximo de 13 meses de seguimento. Todos os pacientes sobreviventes (9/11 foram submetidos a estudo ecocardiográfico antes da alta e nenhum apresentou disfunção valvar aórtica. Em dezembro de 1995, todos que sobreviviam (8/11 foram reavaliados por ecocardiografia e os resultados são mostrados neste trabalho. Concluímos que o reimplante da valva aórtica descrito por David é um método efetivo de tratamento da IAo associada aos AAA e DAA. Mesmo sendo pequeno o número de pacientes e o seguimento desta série, acreditamos que a tentativa de evitar o implante de próteses valvulares é encorajadora para ambos, cirurgião e paciente, em um seleto n

    Full Text Available El presente estudio pretende ahondar en la pregunta por la pertinencia de la perspectiva estética balthasariana dentro del marco del análisis narrativo, una aproximación que clama para sí la etiqueta de la recuperación estética del texto bíblico. Para ello, tomamos lo que según von Balthasar debería ser -a grandes razgos- el contenido de una estética (bíblica teológica. Definida ésta como una articulación de las temáticas de la gloria, el compañero creatural de Dios y la alianza, el ser del hombre es visto como un ser-en-alianza. Al Antiguo Testamento le es de vital importancia la categoría de alianza y la tematiza narrativamente en varias ocasiones. En este escrito se analiza una de ellas, a saber, la transición del poder de Saúl a David, motivada precisamente por la ruptura de la alianza por parte de Saúl. Nos preguntamos cómo es la puesta en escena y particularmente cómo es enfocado el problema del poder. El relato permite al lector visualizar la ´alianza´ injertada en un conflicto de poder donde su legitimidad teológica de éste está enmarcada en el cumplimiento de la alianza que permite limitar la violencia entre los humanos. Así, gracias a una aproximación totalmente literaria, es posible apreciar la textura antropológica y teológica del alegato estético de von Balthasar.The present study attempts to delve deeply into the question of the pertinence of the balthasarian esthetic perspective within the framework of narrative analysis, an approach that claims for itself the label of esthetic recovery of the biblical text. For this purpose, we take what, according to von Balthasar, ought to be -with broad strokes- the content of a theological (biblical esthetics.

  7. Extending David Horrobin's membrane phospholipid theory of schizophrenia: overactivity of cytosolic phospholipase A(2) in the brain is caused by overdrive of coupled serotonergic 5HT(2A/2C) receptors in response to stress.

    Science.gov (United States)

    Eggers, Arnold E

    2012-12-01

    David Horrobin's membrane phospholipid theory of schizophrenia has held up well over time because his therapeutic prediction that dietary supplementation with eicosapentaenoic acid (EPA) would have a therapeutic effect has been partially verified and undergoes continued testing. In the final version of his theory, he hypothesized that there was hyperactivity of phosphoslipase A(2) (PLA(2)) or a related enzyme but did not explain how the hyperactivity came about. It is known that serotonergic 5HT(2A/2C) receptors are coupled to PLA(2), which hydrolyzes both arachidonic acid (AA) and EPA from diacylglycerides at the sn-2 position. In this paper, Horrobin's theory is combined with a previously published theory of chronic stress in which it was hypothesized that a disinhibited dorsal raphe nucleus, the principal nucleus of the serotonergic system, can organize the neuropathology of diseases such as migraine, hypertension, and the metabolic syndrome. The new or combined theory is that schizophrenia is a disease of chronic stress in which a disinhibited DRN causes widespread serotonergic overdrive in the cerebral cortex. This in turn causes overdrive of cPLA(2) and both central and peripheral depletion of AA and EPA. Because EPA is present in smaller amounts, it falls below threshold for maintaining an intracellular balance between AA-derived and EPA-derived second messenger cascades, which leads to abnormal patterns of neuronal firing. There are two causes of neuronal dysfunction: the disinhibited DRN and EPA depletion. Schizophrenia is statistically associated with metabolic syndrome, hypertension, and migraine because they form a cluster of diseases with similar pathophysiology. The theory provides an explanation for both the central and peripheral phospholipid abnormalities in schizophrenia. It also explains the role of stress in schizophrenia, elevated serum PLA(2) activity in schizophrenia, the relationship between untreated schizophrenia and metabolic syndrome

  17. Confronting Inauthenticity – Utopias of David Bowie

    Directory of Open Access Journals (Sweden)

    Pavao Parunov

    2015-06-01

    Full Text Available Bowie consists of twenty-one short chapters that function as a collection of conceptual fragments. Bowie's artistic work already provides a series of different periods each with its own stock of identities which could easily be comprised into different sections of this book according to, as Critchley calls them, illusions he inhabited, both musically and aesthetically. Although a sense of linearity is present, as the author tends to give an overview of albums and his own fan sensibilities, dividing the book according to Bowie's own artistic eras is avoided. The division into twenty-one chapters is much closer to breaking Bowie's work into conceptual categories that are present throughout his career and are related to questions of identity, sexuality and desire or sometimes even Bowie's own life in the background of it all. Still, as the author notes at the very beginning of the book – it is important not to conflate Bowie as a persona of popular music with his work. It is a popular approach in music journalism and production of music biographies to somehow look behind the performance in search of traumas that might have provoked an artist to perform in a specific mode. This is in its own a desire of authenticity always present with popular music that Critchley seeks to deconstruct in order to give more layers to Bowie's music, or as he is approaching it – poetry.
