Waltz's 1979 book, Theory of International Politics, is the most influential in the history of the discipline. It worked its effects to a large extent through raising the bar for what counted as theoretical work, in effect reshaping not only realism but rivals like liberalism...... and reflectivism. Yet, ironically, there has been little attention to Waltz's very explicit and original arguments about the nature of theory. This article explores and explicates Waltz's theory of theory. Central attention is paid to his definition of theory as ‘a picture, mentally formed' and to the radical anti......-empiricism and anti-positivism of his position. Followers and critics alike have treated Waltzian neorealism as if it was at bottom a formal proposition about cause-effect relations. The extreme case of Waltz being so victorious in the discipline, and yet being consistently mis-interpreted on the question of theory...

    Full Text Available Abstract Background Identifying protein-coding regions in genomic sequences is an essential step in genome analysis. It is well known that the proportion of false positives among genes predicted by current methods is high, especially when the exons are short. These false positives are problematic because they waste time and resources of experimental studies. Methods We developed GeneWaltz, a new filtering method that reduces the risk of false positives in gene finding. GeneWaltz utilizes a codon-to-codon substitution matrix that was constructed by comparing protein-coding regions from orthologous gene pairs between mouse and human genomes. Using this matrix, a scoring scheme was developed; it assigned higher scores to coding regions and lower scores to non-coding regions. The regions with high scores were considered candidate coding regions. One-dimensional Karlin-Altschul statistics was used to test the significance of the coding regions identified by GeneWaltz. Results The proportion of false positives among genes predicted by GENSCAN and Twinscan were high, especially when the exons were short. GeneWaltz significantly reduced the ratio of false positives to all positives predicted by GENSCAN and Twinscan, especially when the exons were short. Conclusions GeneWaltz will be helpful in experimental genomic studies. GeneWaltz binaries and the matrix are available online at http://en.sourceforge.jp/projects/genewaltz/.

    Liquid crystals, when confined to a spherical shell, offer fascinating possibilities for producing artificial mesoscopic atoms, which could then self-assemble into materials structured at a nanoscale, such as photonic crystals or metamaterials. The spherical curvature of the shell imposes topological constraints in the molecular ordering of the liquid crystal, resulting in the formation of defects. Controlling the number of defects, that is, the shell valency, and their positions, is a key success factor for the realization of those materials. Liquid crystals with helical cholesteric order offer a promising, yet unexplored way of controlling the shell defect configuration. In this paper, we study cholesteric shells with monovalent and bivalent defect configurations. By bringing together experiments and numerical simulations, we show that the defects appearing in these two configurations have a complex inner structure, as recently reported for simulated droplets. Bivalent shells possess two highly structured defects, which are composed of a number of smaller defect rings that pile up through the shell. Monovalent shells have a single radial defect, which is composed of two nonsingular defect lines that wind around each other in a double-helix structure. The stability of the bivalent configuration against the monovalent one is controlled by c = h/p, where h is the shell thickness and p the cholesteric helical pitch. By playing with the shell geometry, we can trigger the transition between the two configurations. This transition involves a fascinating waltz dynamics, where the two defects come closer while turning around each other. PMID:27493221

    Waltzing guinea pigs are an inbred guinea pig strain with a congenital and progressive balance and hearing disorder. A unique rod-shaped structure is found in the type I vestibular hair cells, that traverses the cell in an axial direction, extending towards the basement membrane. The present study...... estimates the total number of utricular hair cells and supporting cells in waltzing guinea pigs and age-matched control animals using the optical fractionator method. Animals were divided into four age groups (1, 7, 49 and 343 day-old). The number of type I hair cells decreased by 20% in the 343 day......-old waltzing guinea pigs compared to age-matched controls and younger animals. Two-photon confocal laser scanning microscopy using antibodies against fimbrin and betaIII-tubulin showed that the rods were exclusive to type I hair cells. There was no significant change in the length of the filament rods with age...

    The German waltzing guinea pig is a spontaneously mutated strain with severe auditory and vestibular impairment caused by a so far unknown genetic mutation. The animals are born deaf and show a circling behavior. The heterozygote animals of this guinea pig strain have functionally normal hearing and balance. However, these animals have, in earlier studies, shown an increased resistance to noise compared with normal wild-type guinea pigs. In the present study, we explored the functional hearing with auditory brainstem response thresholds before and at different time points after noise exposure. Symptom-free littermates from heterozygote couples of the German waltzing guinea pigs were exclusively used for the study, which, after the hearing test, were sent back for breeding to confirm their genotype (i.e. heterozygote or normal). The aim of this paper was to ascertain that the previously shown reduced susceptibility to noise trauma in the heterozygote animals of the German waltzing guinea pig was also evident when littermates were used as control animals. The findings are important for further analysis of the heterozygote animals of this strain and for future investigations of the underlying mechanisms behind the diverse susceptibility to exposures of loud sound.

    The Waltz Spectrograph is a fiber-fed high-resolution échelle spectrograph for the 72 cm Waltz Telescope at the Landessternwarte, Heidelberg. It uses a 31.6 lines/mm 63.5° blaze angle échelle grating in white-pupil configuration, providing a spectral resolving power of R 65,000 covering the spectral range between 450-800nm in one CCD exposure. A prism is used for cross-dispersion of échelle orders. The spectrum is focused by a commercial apochromat onto a 2k×2k CCD detector with 13.5μm per pixel. An exposure meter will be used to obtain precise photon-weighted midpoints of observations, which will be used in the computation of the barycentric corrections of measured radial velocities. A stabilized, newly designed iodine cell is employed for measuring radial velocities with high precision. Our goal is to reach a radial velocity precision of better than 5 m/s, providing an instrument with sufficient precision and sensitivity for the discovery of giant exoplanets. Here we describe the design of the Waltz spectrograph and early on-sky results.

  12. Balance of power in Waltz's neorealist theory, after the Franco-Prussian War and the unification of Germany

    Directory of Open Access Journals (Sweden)

    Alexandru Voicu

    2014-04-01

    Full Text Available The neorealist theory developed by Kenneth Waltz is one of the most important theories of international relations. The most significant predictions of his theory is that the balancing behavior is a systemic product, which will occur regularly in international relations whether the states want it or not. This papers aims to bring a critical perspective on the concept of balancing as it is developed by Waltz. Therefore, the prediction made by Waltz will be tested against the international system developed at the end of the nineteenth century, particularly after the Franco-Prussian War. Finally, it will be concluded that the parsimony that is characterizing Waltz’s theory is inaccurate because it makes it on one hand irrefutable and on the other hand, it makes it inconsistent.

    There is evidence that aerobic exercise improves functional capacity in patients with New York Heart Association (NYHA) class II and III chronic heart failure. However, it is unknown whether dancing is safe and able to improve functional capacity in patients with chronic heart failure. We prospectively studied 130 patients with stable chronic heart failure (107 men; mean age, 59+/-11 years) in New York Heart Association class II and III and left ventricle ejection fraction dance protocol of alternate slow (5 minutes) and fast (3 minutes) waltz lasting 21 minutes (group D, n=44). A group that did not undergo exercise training served as control (group C, n=42). On study entry and at 8 weeks, all patients underwent cardiopulmonary exercise testing on a cycle ergometer until volitional fatigue, 2D-echo with Doppler, and endothelium-dependent dilation of the brachial artery. Heart rate was 111+/-15 bpm during exercise training and 113+/-19 bpm during dancing (P=0.59). Peak o(2), anaerobic threshold, e/co(2) slope, and o(2)/W slope were all similarly improved in both E and D groups (+16% and 18%, 20% and 21%, 14% and 15%, 18% and 19%, respectively; P not significant for all comparisons; Pdancing is safe and able to improve functional capacity and endothelium-dependent dilation similar to traditional aerobic exercise training. Waltz dancing may be considered in clinical practice in combination with aerobic exercise training or as an alternative to it.

    Abstract (E: Drawing on scholarship on film cognition, the essay argues that Ari Folman's animated documentary Waltz with Bashir effectively recreates the process of recovering memories by capitalizing on the way our brains process films, and by thematizing memory. However, the film's limited contextualization of the 1982 Lebanon War and the lives of the soldiers involved and depicted limits Waltz's ability to make an effective antiwar statement. While the film's impact is not limited to viewers with knowledge of the particular politico-military conflict the film represents, it is limited by the nature and extent of its involvement with its subjects' lives before and after the war.

    With the inauguration of the UK's first ever Medical Film festival MedFest in 2011 there has been resurgence in the interest of the association between psychiatry and film. The festival in 2012 was titled "HealthScreen": Understanding Illness through Film and its aim, according to the founder Dr Kamran Ahmed, was, 'To stimulate debate of the social, political and ethical implications of portrayals of health and illness on our screens' (1). Waltz with Bashir is a 2008 Israeli animated documentary film written and directed by Ari Folman. It portrays the protagonist (Folman) in search of his lost memories of his experience as a soldier in the 1982 Lebanon War and his attempt to both decipher them and reconcile himself with them. 2012 marks the 30th year commemoration of the Sabra and Shatilla tragedies. Waltz with Bashir vividly depicts the massacres of Palestinians in the Sabra and Shatilla refugee camps in Beirut through the lens of an ex-IDF serviceman and the harrowing effects that PTSD has on him. Waltz with Bashir was nominated for an Academy Award for Best Foreign Language Film however despite the popularity of the film and much critical acclaim it is officially banned in Lebanon. The authors are mindful of the devastating effects that the atrocities have had on the mental health of all those who were involved, the Lebanese, Palestinians and also the Israelis. The purpose of this presentation is to explore how the film Waltz with Bashir portrays PTSD and how it has influenced cultural perceptions.

  17. Young and Waltzing Binary Stars

    ADONIS Observes Low-mass Eclipsing System in Orion Summary A series of very detailed images of a binary system of two young stars have been combined into a movie . In merely 3 days, the stars swing around each other. As seen from the earth, they pass in front of each other twice during a full revolution, producing eclipses during which their combined brightness diminishes . A careful analysis of the orbital motions has now made it possible to deduce the masses of the two dancing stars . Both turn out to be about as heavy as our Sun. But while the Sun is about 4500 million years old, these two stars are still in their infancy. They are located some 1500 light-years away in the Orion star-forming region and they probably formed just 10 million years ago . This is the first time such an accurate determination of the stellar masses could be achieved for a young binary system of low-mass stars . The new result provides an important piece of information for our current understanding of how young stars evolve. The observations were obtained by a team of astronomers from Italy and ESO [1] using the ADaptive Optics Near Infrared System (ADONIS) on the 3.6-m telescope at the ESO La Silla Observatory.

This is quite fortunate, as the study of binary stars is the only way in which it is possible to measure directly one of the most fundamental quantities of a star, its mass. The mass of a star determines its fate . Massive stars (with masses more than 50 times that of the Sun) lead a glorious, but short life. They are hot and very luminous and exhaust their energy supply in just a few million years. At the other end of the scale, low-mass stars like the Sun are more economical with their resources. Being cooler and dimmer, they are able to shine for billions of years [2]. But although the mass determines the fate of a star, it is not a trivial matter to measure this crucial parameter. In fact, it can only be determined directly if the star happens to be gravitationally bound to another star in a binary stellar system. Observations of the orbital motions of the two stars as they circle each other allows to "weigh" them, and also provide other important information, e.g. about their sizes and temperatures. Orbital motions The understanding of orbital motions has a long history in astronomy. The basic laws of Johannes Kepler (1571-1630) are still used to calculate the masses of orbiting objects, in the solar system as well as in binary stellar systems. However, while the observations of the motion of the nine planets and moons have allowed us to measure quite accurately the masses of objects in our vicinity, the information needed to "weigh" the binary stellar systems is not that easy to obtain. As a result, the mass estimates of the stars in binary systems are often rather uncertain. A main problem is that the individual stars in many binary systems can not be visually separated, even in the best telescopes. The information about the orbit may then come from the motions of the stars, if these are revealed by spectroscopic observations of the combined light (such systems are referred to as "spectroscopic binaries"). If absorption lines from both components are present in the spectrum, the measured wavelength of these double lines will shift periodically back and forth. This is the well-known Doppler effect and it directly reflects the changing velocities of the stars, as they move along their orbits and periodically approach and recede from the observer. Such spectroscopic observations therefore allow to measure the orbital velocities of the stars. It is exactly the same technique that is used to study and weigh extra-solar planets orbiting other stars [3]. However, this method has an important limitation. From the spectroscopical observations alone, it is only possible to deduce limits on the masses, as the inclination of orbits to the line-of-sight is usually unknown. The masses derived in this way (for stars as well as for exoplanets) are therefore only lower limits on the actual masses. Eclipsing Binaries However, fortunate observational circumstances sometimes allow to obtain all information about the stellar orbits. If a binary system is viewed (almost exactly) edge-on, the stars may pass in front of each other from time to time. Astronomers refer to this phenomenon as an "eclipse" and speak about an "eclipsing binary". The effect is similar to a "solar" eclipse as seen on the Earth, whenever the Moon passes in front of the Sun. Like the Moon blocks the sunlight, less light is received from the eclipsed star and thus the combined light from the binary system decreases during the eclipse. The way this happens (astronomers speak about the system's "lightcurve") then provides the additional information about the inclination of the orbit that is needed to determine exactly the stellar masses in a "spectroscopic" binary system. Very accurate values for the stellar diameters and the surface temperatures of the two stars can also be deduced. In short, when a full set of observations is available, it is possible to give a comprehensive description of an eclipsing binary system and its components. Eclipsing, spectroscopic binaries thus represent true cornerstones for the determination of stellar masses , and as such they are fundamental for our understanding of stellar evolution . Rather few such systems are known, but they can also be used to check ("calibrate") other, indirect methods to derive stellar parameters. It is on this background that the first discovery of an eclipsing binary system with two young, solar-like stars is of great interest. The Orion Binary Young stars are not so easy to find. One way is to look for their high-energy emission from a hot corona, created by their enhanced magnetic activity. The object RXJ 0529.4+0041 was first discovered in this way by the X-ray satellite ROSAT. Subsequent optical spectroscopy showed this object to be a young, low-mass spectroscopic binary system. And when a team of astronomers [1] used a 91-cm telescope at the Serra La Nave observing station on the slope of the Etna volcano (Sicily) to monitor the light curve, they also discovered that this system undergoes eclipses. All data confirm that RXJ 0529.4+0041 is located in the Orion Nebula at a distance of about 1500 light-years. This is one of the nearest star-forming regions and almost all stars in this area are quite young. Spectroscopic observations soon confirmed that the binary system was no exception. In particular, fairly strong absorption lines of the fragile element Lithium [4] were detected in both of the binary stars. As Lithium is known to be rapidly destroyed in stars, the finding of a relatively high content of this element implies that the stars must indeed be young. They were probably formed no more than 10 million years ago, i.e., in astronomical terms, they are "infant" stars . High-resolution spectroscopic observations, mostly with the CORALIE spectrometer on the Swiss 1.2-m Leonard Euler telescope at the ESO La Silla Observatory , were used to determine the radial velocities of the stars. From these, a first determination of the orbital and stellar parameters was possible. The orbital period turned out to be short. The two stars swing around each other in just 3 days. This also means they must be very close to each other (but still entirely detached from each other) - the detailed analysis showed that the distance between the two components is only 12 solar radii, or a little more than 8 million kilometres. If you would image yourself standing on the surface of the smaller star, the disk of the companion star would extend some 15° in the sky. This is 30 times larger than our view of the Sun! ADONIS observations The short orbital period and the even shorter duration of the eclipses, only 6 hours, posed a real challenge for the observers. They decided to obtain further high-angular resolution observations with the ADaptive Optics Near Infrared System (ADONIS) on the 3.6-m telescope at the ESO La Silla Observatory. Most fortunately, early ADONIS images demonstrated that this binary stellar system has a third companion, sufficiently far away from the two others to be seen as a separate star by ADONIS. This unexpected bonus made it possible to monitor the light changes of the binary system in great detail, by using the third companion as a convenient "reference" star. In December 2000 and January 2001, detailed ADONIS images of the RXJ 0529.4+0041 system were obtained in three near-infrared filters (the J-, H- and K-bands). ADONIS is equipped with the SHARP II camera and eliminates the adverse image-smearing effects of the atmospheric turbulence in real-time by means of a computer-controlled flexible mirror. As expected, the new, extremely sharp images of RXJ 0529.4+0041 greatly improved the achievable photometric precision. In particular, as the image of the third component was perfectly separated from the others, it did not "contaminate" the derived light curve of the eclipsing binary.

For a detailed explanation, read the text. ESO PR Video Clip 06/01 [512 x 448 pix MPEG] ESO PR Video Clip 06/01 (150 frames/00:06 min) [MPEG Video; 512 x 448 pix; 871 k] ESO Video Clip 06/01 shows the ADONIS images of the RXJ 0529.4+0041 eclipsing, binary stellar system, as recorded in three near-infrared filters (J, H, and K; to the left), with the observed light-curves (top) and a graphical representation of the system during a full orbit, as it would look like to a nearby observer. More details in the text The ADONIS images have been combined into an instructive movie ( PR Video Clip 06/01 ). The left-hand panel shows the eclipsing binary system (it is the upper right and brighter of the two objects; the light from the two stars merge into a single point of light) and the well visible third component (lower left), as they were recorded by ADONIS in the three different filter bands. As the two stars in the binary system move around each other in their orbits, eclipses occur and the brightness of the binary system clearly changes - it may help to play the movie several times to see this more clearly. For reference, the Universal Time (UT) and the orbital phase (increasing from 0 to 1 during a full revolution) are continuously displayed in the movie. The right-hand panel shows a build-up of the observed light curves for the binary system. It represents the brightness difference between binary system and the third object that shines with constant light. Both the primary, deeper and the secondary, less deep eclipses are well visible. The primary eclipse was observed on December 8, 2000 and is here displayed at phase zero. During this minimum, the brightness of the binary system decreases by about 45% (0.4 magnitudes). The primary eclipse takes place when the smaller component blocks the light from the brighter and hotter star. The orbital motions of the two stars are illustrated by a computer-generated, animated sequence. The secondary eclipse (at phase 0.5) dims the light from the system less; it occurs when the larger and brighter star almost completely (about 90%) hides its smaller companion. The second minimum was recorded on January 12, 2001. None of the eclipses is therefore "total". The stellar parameters A detailed analysis of these high-precision light curves allowed the astronomers to determine the orbits and hence, to perform an extremely accurate measurement of the fundamental stellar parameters for the two young stars of RXJ 0529.4+0041 . The star that is eclipsed during the primary eclipse (the "primary") is the more massive and also the hotter and brighter of the two stars. Its mass is 1.3 times that of our Sun, i.e., about 2.6 10 30 kg [2]. Its diameter is nearly 1.6 times larger than that of our Sun (i.e., about 2.2 million km) and the surface temperature is found to be a little more than 5000 °C, or a few hundred degrees cooler than the Sun. The "secondary" star is slightly lighter than our Sun. Its weight is about 90% of that of the Sun (1.8 10 30 kg) and the diameter is 20% larger (about 1.7 million km), while the surface temperature is 4000 degrees. In fact, these two stars are still so young that most of their energy comes from the contraction process - the first phase during which they are formed from an interstellar cloud by this process is not yet over and they are still getting smaller. It is by this process that collapsing stars heat up enough to start nuclear burning. When infant stars in RXJ 0529.4+0041 eventually reach middle-age, their sizes will most likely also be quite similar to that of the Sun. The significance of RXJ 0529.4+0041 Few systems are known for which such precise determinations of the stellar parameters have ever been possible - and this binary system represents the first case where both the components are such young stars . A detailed comparison of the derived stellar parameters with current models for the evolution of young stars shows fairly good agreement for the primary component. However, there are certain discrepancies in the case of the secondary component, showing that the current models for the early stages of lower-mass stars must still be refined. More information Part of the results described in this press release are described in more detail in a scientific article ( "RXJ 0529.4+0041: a low-mass pre-main sequence eclipsing-spectroscopic binary" by E. Covino et al.) that has been published in the European research journal Astronomy & Astrophysics (Vol. 361, p. 49). Notes [1] The team consists of Elvira Covino (Principal Investigator), Juan M. Alcalá , Rosita Paladino (all Osservatorio Astronomico di Capodimonte, Napoli, Italy), Antonio Frasca , Santo Catalano , Ettore Marilli (all Osservatorio Astrofisico di Catania, Italy) and Michael Sterzik (ESO-Chile). [2] One solar mass corresponds to 1.99 10 30 kg, or about 330,000 times the mass of the Earth. The Sun is about 4500 million years old and its total lifetime is of the order of 12-13,000 million years. It is an interesting thought that if the Sun would have been somewhat heavier, its total lifetime might have been too short for living organisms to develop on the Earth. In fact, the biological evolution that ultimately lead to the emergence of human beings apparently lasted about 4 billion years; this corresponds to the total lifetime of a star that is only about 20 % heavier than the Sun. Note also the current ESO-ESA CERN educational programme on "Life in the Universe". [3] In the case of exoplanets, the planet itself is not visible, but the spectral lines from the star are seen to wobble due to the gravitational influence of the planet, cf. ESO PR 07/01. [4] Several ESO Press Releases concern observations of the element Lithium in stars, e.g., PR 03/99 (in a giant star), PR 08/00 (in a metal-poor star) and PR 10/01 (from a "swallowed" exoplanet).

    Full Text Available Composta por Radamés Gnattali (1906-1988 em 1956 para bandolim solista, conjunto de choro e orquestra de cordas, Retratos é uma suíte em quatro movimentos onde são homenageadas algumas das mais expressivas personalidades do cenário da música popular brasileira: Pixinguinha, Ernesto Nazareth, Anacleto de Medeiros e Chiquinha Gonzaga. O que dá forma e sustenta a narrativa da obra é a ideia de que os movimentos constituem retratos musicais destes compositores. Assim, a estrutura de cada movimento foi elaborada a partir de um modelo, ou seja, de cada compositor Gnattali escolheu uma peça que serviria de roteiro para o processo criativo dos retratos. Este estudo tem como foco o segundo movimento da suíte, a valsa, observando como está relacionado ao seu respectivo modelo, a valsa Expansiva de Ernesto Nazareth (1863-1934. Para ilustrar o paralelo será apresentada uma análise mais comparativa do que formal, procurando ampliar a visão do contexto histórico com evidências musicais, concentrando-se principalmente nos elementos comuns a ambas as peças.Written in 1956 by Brazilian composer Radamés Gnattali (1906-1988 for solo mandolin, choro ensemble and strings orchestra, Retratos (namely, Portraits in Portuguese is a four movement suite that pays homage to some of the most significant personalities in the history of Brazilian popular music: Pixinguinha, Ernesto Nazareth, Anacleto de Medeiros and Chiquinha Gonzaga. What shapes and supports the suite's narrative is the idea that the movements represent musical portraits of these composers. As a result, each movement was structured after a model, that is, Gnattali has chosen a particular piece by each composer that would serve as a blueprint for the creative process of the portraits. The focus of this study is the suite's second movement, the waltz, observing how it is related to its respective model, the waltz Expansiva by Ernesto Nazareth (1863-1934.

  1. Waltz of the couples: change partners, please.

    Science.gov (United States)

    Haskey, J

    1992-05-01

    Marriage, cohabitation, and divorce all concern family planners, sex educators, and health educators because of their impact on childbearing. Marriage has changed in the last 2-3 decades as more couples decide to permanently cohabit or cohabit before marriage, marriage rates have fallen and 1st marriages occur later, more women have become single mothers, and divorce has increased. Divorced individuals usually remarry, especially the younger ones, although the rate for remarriage has declined sharply in the last 20 years. Evidence suggests that cohabitation is highest among the separated and divorced (apparently slowing their remarriage rate), and is lowest among the single and widowed. The highest rate for women cohabiting is invariably found in the early 20's age group: between 3-4 in every 10 in Norway, Denmark, and Sweden and between 1-2 in every 10 in Switzerland, Great Britain, France, and the Netherlands. In Ireland, Italy, and Belgium, the rate is comparatively low, suggesting wide variations between European countries. The changes in marriage are "most pronounced in the north of Europe, followed by the west, and least pronounced in the east and the south." These patterns most likely will continue for the immediate future, although divorce may be stabilizing at relatively high rates, in some European countries.

    Full Text Available Rhythmic information plays an important role in Music Information Retrieval. Example applications include automatically annotating large databases by genre, meter, ballroom dance style or tempo, fully automated D.J.-ing, and audio segmentation for further retrieval tasks such as automatic chord labeling. In this article, we therefore provide an introductory overview over basic and current principles of tempo detection. Subsequently, we show how to improve on these by inclusion of ballroom dance style recognition. We introduce a feature set of 82 rhythmic features for rhythm analysis on real audio. With this set, data-driven identification of the meter and ballroom dance style, employing support vector machines, is carried out in a first step. Next, this information is used to more robustly detect tempo. We evaluate the suggested method on a large public database containing 1.8 k titles of standard and Latin ballroom dance music. Following extensive test runs, a clear boost in performance can be reported.

    Full Text Available Social contributions have an important impact on payroll policy. Also, social contributions represent a significant budgetary revenue item which can be viewed at the edge between taxation and insurance. Social contributions in Romania experienced many changes which ended in 2008. Nowadays, they are within a long transaction period towards partial externalization of the insurance activity to privately managed funds. The aim of this paper is to analyse the homogeneity of Romanian social security public scheme using annual data extracted from 2002-2009.The main findings reveal that social contributions reached the pinnacle of diversification, being too many, some of them with a small contribution rates; fiscal reforms which reduced contribution rates advantaged employers, and state will be interested to externalize this activity as far private sector will be able to assume this responsibility and the budgetary effects are acceptable for the public finance.

They have been rewarded for their work in enhancing the design of contracts, i.e. arrangements connecting employers with employees or companies with clients, in other words, for their contribution to contract theory in the 1970s and 1980s. Their analysis of optimal contractual arrangements lays an intellectual foundation for designing policies and institutions in many areas, from bankruptcy legislation to political constitutions. Hart is an expert in contract theory, theory of the firm, corporate finance, and law and economics. His contribution to contract theory is exquisite when it comes to designing contracts which cover eventualities that cannot be precisely specified in advance.

    Starting in the middle of the nineteenth century, as part of their scientific tradition, Jesuits founded a considerable number of meteorological observatories throughout the world. In many countries, Jesuits established and maintained the first meteorological stations during the period from 1860 to 1950. The Jesuits' most important contribution to atmospheric science was their pioneer work related to the study and forecast of tropical hurricanes. That research was carried out at observatories of Belén (Cuba), Manila (Philippines), and Zikawei (China). B. Viñes, M. Decheyrens, J. Aigué, and C.E. Deppermann stood out in this movement.

  3. Ergonomics Contribution in Maintainability

    Teymourian, Kiumars; Seneviratne, Dammika; Galar, Diego

    2017-09-01

    The objective of this paper is to describe an ergonomics contribution in maintainability. The economical designs, inputs and training helps to increase the maintainability indicators for industrial devices. This analysis can be helpful, among other cases, to compare systems, to achieve a better design regarding maintainability requirements, to improve this maintainability under specific industrial environment and to foresee maintainability problems due to eventual changes in a device operation conditions. With this purpose, this work first introduces the notion of ergonomics and human factors, maintainability and the implementation of assessment of human postures, including some important postures to perform maintenance activities. A simulation approach is used to identify the critical posture of the maintenance personnel and implements the defined postures with minimal loads on the personnel who use the equipment in a practical scenario. The simulation inputs are given to the designers to improve the workplace/equipment in order to high level of maintainability. Finally, the work concludes summarizing the more significant aspects and suggesting future research.

  4. EMSL Contribution Plan

    2008-12-01

    This Contribution Plan is EMSL’s template for achieving our vision of simultaneous excellence in all aspects of our mission as a national scientific user facility. It reflects our understanding of the long-term stewardship we must work toward to meet the scientific challenges faced by the Department of Energy (DOE) and the nation. During the next decade, we will implement the strategies contained in this Plan, working closely with the scientific community, our advisory committees, DOE’s Office of Biological and Environmental Research, and other key stakeholders. This Plan is fully aligned with the strategic plans of DOE, its Office of Science, and the Pacific Northwest National Laboratory (PNNL). We recognize that shifts in science and technology, national priorities, and resources made available through the Federal budget process create planning uncertainties and, ultimately, a highly dynamic planning environment. Accordingly, this Plan should be viewed as a living document and we continually evaluate the changing needs and opportunities posed by our stakeholders (i.e., DOE, users, staff, advisory committees), work closely with them to understand and respond to those changes, and align our strategy accordingly. This Plan is organized around two sections. Section 1 describes our vision and four strategic outcomes: 1) Scientific Innovation, 2) Capabilities that Transform Science, 3) Outstanding Management and Operations, and Engaged and Proactive Users. These outcomes provide the framework for seven critical actions we must take during the next 3 to 5 years: 1) Establishing leadership in EMSL science themes, 2) building and deploying transformational capabilities, 3) integrating computation with experiment, 4) ensuring EMSL’s workforce meets the scientific challenges of the future, 5) creating partnerships, 6) attracting and engaging users in EMSL’s long-term strategy, and 7) building a research infrastructure that meets emerging scientific needs.

  13. Waltzing of a helium pair in tungsten: Migration barrier and trajectory revealed from first-principles

    Directory of Open Access Journals (Sweden)

    J. G. Niu

    2014-06-01

    Full Text Available Despite well documented first-principles theoretical determination of the low migration energy (0.06 eV of a single He in tungsten, fully quantum mechanical calculations on the migration of a He pair still present a challenge due to the complexity of its trajectory. By identifying the six most stable configurations of the He pair in W and decomposing its motion into rotational, translational, and rotational-translational routines, we are able to determine its migration barrier and trajectory. Our density functional theory calculations demonstrate a He pair has three modes of motion: a close or open circular two-dimensional motion in (100 plane with an energy barrier of 0.30 eV, a snaking motion along [001] direction with a barrier of 0.30 eV, and a twisted-ladder motion along [010] direction with the two He swinging in the plane (100 and a barrier of 0.31 eV. The graceful associative movements of a He pair are related to the chemical-bonding-like He-He interaction being much stronger than its migration barrier in W. The excellent agreement with available experimental measurements (0.24–0.32 eV on He migration makes our first-principles result a solid input to obtain accurate He-W interatomic potentials in molecular dynamics simulations.

  18. Seasonal contributions to climate feedbacks

    Energy Technology Data Exchange (ETDEWEB)

    Colman, R. [Bureau of Meteorology Research Centre, GPO Box 1289K, Melbourne, VIC (Australia)

    2003-05-01

    Heading Abstract. This study addresses the question: how do the contributions to feedbacks in a climate model vary over the seasonal cycle? To answer this the feedbacks are evaluated from an equilibrium doubled CO{sub 2} experiment performed using the Bureau of Meteorology Research Centre (BMRC) General Circulation Model. Monthly means of the top-of-atmosphere radiative perturbations (which together comprise the annual climate feedbacks) are extracted to produce a mean annual cycle. It is found that the radiative contributions to the total longwave (LW) feedback are fairly constant throughout the year. Those to the total shortwave (SW) feedback, on the other hand, vary by a factor of three, from a maximum in July to a minimum in November. Of the LW feedbacks, contributions to the lapse rate shows greatest seasonal variation, while those to water vapour and cloud feedbacks vary by relatively small amounts throughout the year. Contributions to the lapse rate feedback as a function of surface type and latitude reveal conflicting positive and negative radiative perturbations, which vary most strongly at high latitudes. Of the SW feedbacks, contributions to both albedo and cloud show large seasonal variations. Radiative perturbations contributing to albedo feedback vary in strength with snow and sea-ice retreat which occurs at different latitudes and in different months. They are shown to be highly sensitive to the amount of incident solar radiation in a given month. SW radiative perturbations due to cloud changes vary in sign between opposite seasons. Contributions to the seasonal variations of the cloud component feedbacks, which make up the total cloud feedback, are also examined. In the LW, the feedback is dominated by the total cloud water term. Radiative perturbations due to this component show relatively little variation throughout the year. In the SW, the main source of seasonal variation occurs for contributions to the cloud amount feedback: radiative

    To review Australian contributions to global immunisation. We summarise Australian scientific and program contributions to vaccines and global immunisation, describe key developments and strengths in Australia's national immunisation program, and outline how both of these can link with Australia's increasing international development budget to build Australia's future contribution to global immunisation. Australian contributions to vaccines and immunisation have been substantial, and Australia offers a range of good practices in its domestic and development approaches. There are major opportunities to build on this strong track record. These include committing to help roll out important new life-saving vaccines against pneumococcal disease, rotavirus and human papilloma virus (HPV) to the children who need them most, but whose communities can least afford them. Australia is one of a few countries expanding their aid budgets towards 0.7% development assistance and other development commitments. Given the importance of immunisation to health gains, Australia is well placed to expand its investment in immunisation within its development portfolio. The GAVI Alliance is the best-established global mechanism to do this. Additionally, however, Australia could harness other national and regional mechanisms to support low and middle-income countries, thereby complementing GAVI's focus and global needs. © 2012 The Authors.

    Both fresh and processed foods make up vital parts of the food supply. Processed food contributes to both food security (ensuring that sufficient food is available) and nutrition security (ensuring that food quality meets human nutrient needs). This ASN scientific statement focuses on one aspect of processed foods: their nutritional impacts. Specifically, this scientific statement 1) provides an introduction to how processed foods contribute to the health of populations, 2) analyzes the contribution of processed foods to "nutrients to encourage" and "constituents to limit" in the American diet as recommended by the Dietary Guidelines for Americans, 3) identifies the responsibilities of various stakeholders in improving the American diet, and 4) reviews emerging technologies and the research needed for a better understanding of the role of processed foods in a healthy diet. Analyses of the NHANES 2003-2008 show that processed foods provide both nutrients to encourage and constituents to limit as specified in the 2010 Dietary Guidelines for Americans. Of the nutrients to encourage, processed foods contributed 55% of dietary fiber, 48% of calcium, 43% of potassium, 34% of vitamin D, 64% of iron, 65% of folate, and 46% of vitamin B-12. Of the constituents to limit, processed foods contributed 57% of energy, 52% of saturated fat, 75% of added sugars, and 57% of sodium. Diets are more likely to meet food guidance recommendations if nutrient-dense foods, either processed or not, are selected. Nutrition and food science professionals, the food industry, and other stakeholders can help to improve the diets of Americans by providing a nutritious food supply that is safe, enjoyable, affordable, and sustainable by communicating effectively and accurately with each other and by working together to improve the overall knowledge of consumers. © 2014 American Society for Nutrition.

    Galileo Galilei (1564-1642), world-renowned Italian mathematician, astronomer, physicist and philosopher, made many contributions to science. The objective of this study is to demonstrate that Galileo's discovery of scaling principles permitted others to define and advance orthopaedic research and clinical sciences. The science and scaling principles of Galileo Galilei were extensively analyzed by reviewing his 1638 original work Discorsi e Demostrazioni Matematiche Intorno a Due Nuove Scienze. Works about Galileo's science were reviewed for the concept of the scaling principles and with the idea of shedding light on how his work influenced modern orthopaedics. Galileo strictly adhered to the Copernican heliocentric theory with the sun at the center of the universe, which caused him aggravation and made him the target of inquisition rage at the end of his prodigious life. With his attention away from the cosmos, Galileo--through the voices of Salviati, Sagredo and Simplicio in the Discourses on Two New Sciences--defined how scaling was important to the movement and function of objects. Galileo introduced important advances in scaling laws, which contributed to the development of the field of biomechanics. This discipline, in many ways, has defined modern clinical and research orthopaedics. Galileo, by introducing the principles of scaling, permitted their application to human physical capacity, to bone and tissue response after injury, and to clinical treatment of injuries. Galileo in this way made important contributions to the practice of modern orthopaedics.

Here, we test the hypothesis that the cerebellum contributes to social cognition through EA from faces. We examined 57 patients with cerebellar disorders and 57 healthy controls. Thirty-one patients had complex cerebrocerebellar disease (complex cerebrocerebellar disease group (CD)); 26 had disease isolated to cerebellum (isolated cerebellar disease group (ID)). EA was measured with the Reading the Mind in the Eyes test (RMET), and informants were administered a novel questionnaire, the Cerebellar Neuropsychiatric Rating Scale (CNRS).

    Heinrich Obersteiner (1847-1921) was amongst the most influential neuroscientists in the 19th century. Born into a family of physicians, he gained early exposure to medicine, and as a medical student, he focused much of his research in neuroanatomy, eventually becoming a professor of neuroanatomy at the University of Vienna. Throughout his academic career, he focused greatly on neuropathology, and incorporated much of his research into his textbook, "Introduction to the Study of the Structure of the Central Nervous Organs in Health and Disease," which was considered the foremost reference text of neurology for many generations of scholars. The culmination of his contributions to the neurological world can be seen as the Neurological Institute of Vienna, which he founded in 1882. Scholars from all over the world sought out his expertize and tutelage. While he was the director of the Institute, over 500 articles were published within the Obersteiner-Arbeiten. Much of this work helped set the foundation for the eventual development of neurology as a medical discipline. A review of his life will help us better understand the legacy Heinrich Obersteiner left in the field of neurology. © 2014 Wiley Periodicals, Inc.

    Starting from a molecular picture for the X(3872) resonance, this state and its J{sup PC} = 2{sup ++} heavy-quark spin symmetry partner [X{sub 2}(4012)] are analyzed within a model which incorporates possible mixings with 2P charmonium (c anti c) states. Since it is reasonable to expect the bare χ{sub c1}(2P) to be located above the D anti D{sup *} threshold, but relatively close to it, the presence of the charmonium state provides an effective attraction that will contribute to binding the X(3872), but it will not appear in the 2{sup ++} sector. Indeed in the latter sector, the χ{sub c2}(2P) should provide an effective small repulsion, because it is placed well below the D{sup *} anti D{sup *} threshold. We show how the 1{sup ++} and 2{sup ++} bare charmonium poles are modified due to the D{sup (*)} anti D{sup (*)} loop effects, and the first one is moved to the complex plane. The meson loops produce, besides some shifts in the masses of the charmonia, a finite width for the 1{sup ++} dressed charmonium state. On the other hand, X(3872) and X{sub 2}(4012) start developing some charmonium content, which is estimated by means of the compositeness Weinberg sum rule. It turns out that in the heavy-quark limit, there is only one coupling between the 2P charmonia and the D{sup (*)} anti D{sup (*)} pairs. We also show that, for reasonable values of this coupling, leading to X(3872) molecular probabilities of around 70-90 %, the X{sub 2} resonance destabilizes and disappears from the spectrum, becoming either a virtual state or one being located deep into the complex plane, with decreasing influence in the D{sup *} anti D{sup *} scattering line. Moreover, we also discuss how around 10-30 % charmonium probability in the X(3872) might explain the ratio of radiative decays of this resonance into ψ(2S)γ and J/ψγ. Finally, we qualitatively discuss within this scheme, the hidden bottom flavor sector, paying a special attention to the implications for the X{sub b} and X

  18. The contribution of technology to added value

    CERN Document Server

    Fernandes, António S C

    2013-01-01

    There is a wide consensus that introduction of technology to the production process contributes to an overall economic value, however, confusion between technology, knowledge and capital often makes value calculations ambiguous and non-objective. The Contribution of Technology to Added Value addresses not only this issue of definition but also provides a production model to assess the value contribution of technology within the production process. A clarification  of fundamental semantics  provides a significant taxonomy for technology dependence, and allows understanding and modeling of how knowledge, technology and capital individually contribute to production and to value adding. A new technology dependence taxonomy is proposed and assessed following chapters explaining growth models, the KTC model and technology index values. Balancing theoretical knowledge with real-world data and applications The Contribution of Technology to Added Value clarifies the issue of value adding for a range of different vie...

  19. The economic contribution of tourism in Mozambique

    Jones, Edward Samuel

    2010-01-01

    How much tourism contributes to the economies of developing countries is controversial and often not measured rigorously. Focusing on Mozambique, this study presents a simple accounting tool – a tourist-focused Social Accounting Matrix – which makes it possible to estimate the economic contribution...... of various tourism sub-types. Multiplier analysis is applied to evaluate the strength of backward linkages from tourism to the domestic economy. The results show the sector is moderate in size but has the potential to contribute significantly to aggregate economic development. However, potential weaknesses...... are already evident and careful attention must be paid to the full tourism value chain....

  2. The contribution of glacier melt to streamflow

    Energy Technology Data Exchange (ETDEWEB)

    Schaner, Neil; Voisin, Nathalie; Nijssen, Bart; Lettenmaier, D. P.

    2012-09-13

    Ongoing and projected future changes in glacier extent and water storage globally have lead to concerns about the implications for water supplies. However, the current magnitude of glacier contributions to river runoff is not well known, nor is the population at risk to future glacier changes. We estimate an upper bound on glacier melt contribution to seasonal streamflow by computing the energy balance of glaciers globally. Melt water quantities are computed as a fraction of total streamflow simulated using a hydrology model and the melt fraction is tracked down the stream network. In general, our estimates of the glacier melt contribution to streamflow are lower than previously published values. Nonetheless, we find that globally an estimated 225 (36) million people live in river basins where maximum seasonal glacier melt contributes at least 10% (25%) of streamflow, mostly in the High Asia region.

  16. Incentives to Encourage Scientific Web Contribution (Invited)

    Science.gov (United States)

    Antunes, A. K.

    2010-12-01

    We suggest improvements to citation standards and creation of remuneration opportunities to encourage career scientist contributions to Web2.0 and social media science channels. At present, agencies want to accomplish better outreach and engagement with no funding, while scientists sacrifice their personal time to contribute to web and social media sites. Securing active participation by scientists requires career recognition of the value scientists provide to web knowledge bases and to the general public. One primary mechanism to encourage participation is citation standards, which let a contributor improve their reputation in a quantifiable way. But such standards must be recognized by their scientific and workplace communities. Using case studies such as the acceptance of web in the workplace and the growth of open access journals, we examine what agencies and individual can do as well as the time scales needed to secure increased active contribution by scientists. We also discuss ways to jumpstart this process.

  2. Neutron contribution to nuclear DVCS asymmetries

    2008-01-22

    Using a simple model for nuclear GPDs, we study the role of the neutron contribution to nuclear DVCS observables. As an example, we use the beam-spin asymmetry $A_{LU}^A$ measured in coherent and incoherent DVCS on a wide range of nuclear targets in the HERMES and JLab kinematics. We find that at small values of the momentum transfer $t$, $A_{LU}^A$ is dominated by the coherent-enriched contribution, which enhances $A_{LU}^A$ compared to the free proton asymmetry $A_{LU}^p$, $A_{LU}^A(\\phi)/A_{LU}^p(\\phi)=1.8-2.2$. At large values of $t$, the nuclear asymmetry is dominated by the incoherent contribution and $A_{LU}^A/(\\phi)A_{LU}^p(\\phi)=0.66-0.74$. The deviation of $A_{LU}^A(\\phi)/A_{LU}^p(\\phi)$ from unity at large $t$ is a result of the neutron contribution, which gives a possibility to constain neutron GPDs in incoherent nuclear DVCS. A similar trend is expected for other DVCS asymmetries.

  19. Mechanism Design for Incentivizing Social Media Contributions

    Science.gov (United States)

    Singh, Vivek K.; Jain, Ramesh; Kankanhalli, Mohan

    Despite recent advancements in user-driven social media platforms, tools for studying user behavior patterns and motivations remain primitive. We highlight the voluntary nature of user contributions and that users can choose when (and when not) to contribute to the common media pool. A Game theoretic framework is proposed to study the dynamics of social media networks where contribution costs are individual but gains are common. We model users as rational selfish agents, and consider domain attributes like voluntary participation, virtual reward structure, network effect, and public-sharing to model the dynamics of this interaction. The created model describes the most appropriate contribution strategy from each user's perspective and also highlights issues like 'free-rider' problem and individual rationality leading to irrational (i.e. sub-optimal) group behavior. We also consider the perspective of the system designer who is interested in finding the best incentive mechanisms to influence the selfish end-users so that the overall system utility is maximized. We propose and compare multiple mechanisms (based on optimal bonus payment, social incentive leveraging, and second price auction) to study how a system designer can exploit the selfishness of its users, to design incentive mechanisms which improve the overall task-completion probability and system performance, while possibly still benefiting the individual users.

    Full Text Available The main purpose of this study was to determine the relative contributions of the aerobic and glycolytic systems during an incremental exercise test (IET. Ten male recreational long-distance runners performed an IET consisting of three-minute incremental stages on a treadmill. The fractions of the contributions of the aerobic and glycolytic systems were calculated for each stage based on the oxygen uptake and the oxygen energy equivalents derived by blood lactate accumulation, respectively. Total metabolic demand (WTOTAL was considered as the sum of these two energy systems. The aerobic (WAER and glycolytic (WGLYCOL system contributions were expressed as a percentage of the WTOTAL. The results indicated that WAER (86-95% was significantly higher than WGLYCOL (5-14% throughout the IET (p < 0.05. In addition, there was no evidence of the sudden increase in WGLYCOL that has been previously reported to support to the "anaerobic threshold" concept. These data suggest that the aerobic metabolism is predominant throughout the IET and that energy system contributions undergo a slow transition from low to high intensity

  18. Induced axial and lateral color surface contributions.

    Science.gov (United States)

    Berner, Andrea; Nobis, Thomas; Gross, Herbert

    2017-05-01

    Induced aberrations in general are higher-order aberrations caused by ray perturbations of lower order, picked up in the preceding optical system. Therefore, in the case of color aberrations, induced influences can already be observed at the second order. They are generated by the preexisting first-order axial and lateral color. The analysis of relevant designs surface by surface to identify performance dominating lenses is a key method for understanding and optimizing those systems. Hence, in this paper a formula for the surface contribution of axial and lateral color including second-order terms is derived and discussed differentiating between intrinsic and induced parts. It is also shown how this can be used to deduce a thick-lens contribution of the second order. All of the approaches are based on the Seidel concept, which characterizes any arbitrary optical system only by the paraxial marginal and chief ray of the primary wavelength.

  20. Some feminist contributions to community social psychology

    Directory of Open Access Journals (Sweden)

    2014-02-01

    Full Text Available This article analyzes the contributions of feminist debate about intersectionality of social categories for Community Social Psychology in Brazil. This was set up as dedicated to theoretical analyze the social inequalities that characterize contemporary societies and propose methodological processes of intervention for questioning and processing of these realities. We discuss how the emergence of new actors and demands on public space, as distinct from the 60/70, is required to understand the oppression from various power systems such as gender, race and sexuality. We conclude that intersectional analysis should consider different levels of relationships between categories, the history of the same differential and common aspects of different systems of power as naturalization of inequality, the relationship between public and private relationship between equality and difference. Analyses based on intersectionality can contribute to processes of social intervention that considers the complexity of contemporary societies.

  1. Contributions of Egyptian Women in Physics (abstract)

    El Nadi, Lotfia

    2009-04-01

    Physics is a dynamic, global field. Progress in research motivates scientists to explore new areas and find useful applications for their work. Femtosecond ultrashort pulsed lasers and progress in nanostructures to study the properties of extremely dense matter, as well as one-dimensional materials, are two examples of innovations that encourage students and scientists—male and female—to pursue physics. Young Egyptian women's contributions to physics grew from 46% in 2003 to 69% in 2008. This paper discusses the role of women in physics in Egypt; presents statistics regarding their contributions and presence at Egyptian universities and institutes; and gives information about their decision making leadership roles. Ideas, applicable in Egypt as well as in developing countries, to address problems facing women are raised.

  8. Group Contribution Methods for Phase Equilibrium Calculations.

    Gmehling, Jürgen; Constantinescu, Dana; Schmid, Bastian

    2015-01-01

    The development and design of chemical processes are carried out by solving the balance equations of a mathematical model for sections of or the whole chemical plant with the help of process simulators. For process simulation, besides kinetic data for the chemical reaction, various pure component and mixture properties are required. Because of the great importance of separation processes for a chemical plant in particular, a reliable knowledge of the phase equilibrium behavior is required. The phase equilibrium behavior can be calculated with the help of modern equations of state or g(E)-models using only binary parameters. But unfortunately, only a very small part of the experimental data for fitting the required binary model parameters is available, so very often these models cannot be applied directly. To solve this problem, powerful predictive thermodynamic models have been developed. Group contribution methods allow the prediction of the required phase equilibrium data using only a limited number of group interaction parameters. A prerequisite for fitting the required group interaction parameters is a comprehensive database. That is why for the development of powerful group contribution methods almost all published pure component properties, phase equilibrium data, excess properties, etc., were stored in computerized form in the Dortmund Data Bank. In this review, the present status, weaknesses, advantages and disadvantages, possible applications, and typical results of the different group contribution methods for the calculation of phase equilibria are presented.

  9. The contribution of epidemiology to psychosomatic medicine.

    Science.gov (United States)

    Lobo, A; Campos, R

    1997-01-01

    To discuss the contribution of epidemiology and epidemiological methods to psychosomatic medicine. Critical review of the literature, including both philosophical concepts and empirical data. The adjective "psychosomatic" has been used in two different ways: in the so called "psychosomatic" or holistic approach to medicine; and in a narrower approach, referring to particular disorders in which psychological factors were considered to have a fundamental aetiological role. While the ideal of the holistic, "humanistic" or "anthropological" approach should probably be never abandoned, the practical limitations of encompassing models, including Engel's bio-psycho-social model are also obvious: they may be heuristically sterile. On the other side, in relation to the narrow psychosomatic approach, psychogenetic views in the so called "psychosomatic illnesses" have been strongly criticized on empirical grounds. The potential of epidemiological methods to study these illnesses, but also "somatopsychic" disorders is shown in a number of papers in the empirical literature. We have grouped such contributions, including our own experience, in the five categories suggested by M. Shephered for epidemiological methods in general: 1) the completion of the spectrum of disease; 2) the establishment of outcome; 3) the actuarial assessment of morbid risk; 4) the evaluation of the efficacy of treatment; and 5) the conceptual construction of diagnosis and classification. The contribution of epidemiological data to areas of interest in psychosomatic medicine has been relevant in recent years. The potential of epidemiological methods in this area is very important both to increase knowledge and to improve the quality of clinical practice.

    Poole Wilson, Tiffany; Davis, Kermit G

    2016-08-01

    The aim of this study was to assess the contributions of Thomas Waters's work in the field of health care ergonomics and beyond. Waters's research of safe patient handling with a focus on reducing musculoskeletal disorders (MSDs) in health care workers contributed to current studies and prevention strategies. He worked with several groups to share his research and assist in developing safe patient handling guidelines and curriculum for nursing students and health care workers. The citations of articles that were published by Waters in health care ergonomics were evaluated for quality and themes of conclusions. Quality was assessed using the Mixed Methods Appraisal Tool and centrality to original research rating. Themes were documented by the type of population the citing articles were investigating. In total, 266 articles that referenced the top seven cited articles were evaluated. More than 95% of them were rated either medium or high quality. The important themes of these citing articles were as follows: (a) Safe patient handling is effective in reducing MSDs in health care workers. (b) Shift work has negative impact on nurses. (c) There is no safe way to manually lift a patient. (d) Nurse curriculums should contain safe patient handling. The research of Waters has contributed significantly to the health care ergonomics and beyond. His work, in combination with other pioneers in the field, has generated multiple initiatives, such as a standard safe patient-handling curriculum and safe patient-handling programs. © 2016, Human Factors and Ergonomics Society.

  11. Perturbative QCD contributions to inclusive processes

    Energy Technology Data Exchange (ETDEWEB)

    Ritbergen, T. van

    1996-09-24

    This thesis treats the calculation of quantum corrections to a number of high energy processes that are measured in current and future accelerator experiments. The main objective of these experiments is to accurately verify the generally accepted theory of electro-weak and strong interactions, known as the Standard model, and to look for possible deviations. Most of the processes that are treated in this thesis are of a type for which the final state of of a highly energetic scattering or decay process is measured inclusively. The higher order quantum corrections discussed in this thesis are due to strong interactions. To the inclusive decay rate of Z{sup 0} bosons into all possible final states consisting of hadrons third order QCD contributions have been obtained. Also in the third order QCD an expansion for the inclusive hadronic decay rate of a {tau}-lepton was obtained. Then the top-quark-mass effects on the decay channels of a Higgs boson: Higgs{yields}b-quarks and Higgs{yields}gluons, were investigated. Thereafter the calculation of 3-loop contributions to the deep-inelastic lepton-nucleon scattering process is discussed. Finally the 3-loop contributions to the q{sup 2}-dependence of the lower moments {integral}{sub 0}{sup 1}x{sup N-1}F(x,q{sup 2})dx, N=2,4,6,8 of the structure functions F{sub 2} and F{sub L} were obtained.

  12. Active and passive contributions to spatial learning.

    Chrastil, Elizabeth R; Warren, William H

    2012-02-01

    It seems intuitively obvious that active exploration of a new environment will lead to better spatial learning than will passive exposure. However, the literature on this issue is decidedly mixed-in part, because the concept itself is not well defined. We identify five potential components of active spatial learning and review the evidence regarding their role in the acquisition of landmark, route, and survey knowledge. We find that (1) idiothetic information in walking contributes to metric survey knowledge, (2) there is little evidence as yet that decision making during exploration contributes to route or survey knowledge, (3) attention to place-action associations and relevant spatial relations contributes to route and survey knowledge, although landmarks and boundaries appear to be learned without effort, (4) route and survey information are differentially encoded in subunits of working memory, and (5) there is preliminary evidence that mental manipulation of such properties facilitates spatial learning. Idiothetic information appears to be necessary to reveal the influence of attention and, possibly, decision making in survey learning, which may explain the mixed results in desktop virtual reality. Thus, there is indeed an active advantage in spatial learning, which manifests itself in the task-dependent acquisition of route and survey knowledge.

  13. Protestant ethic: Contributing towards a meaningful workplace

    Directory of Open Access Journals (Sweden)

    Petrus L. Steenkamp

    2013-01-01

    Full Text Available Little did Max Weber know that his essay ‘Protestant ethic and the spirit of capitalism’, written in 1905 (which was republished in 1920, would survive the times and still be a source for discussion and interpretation during the 21st century. Today as in previous times, work and the workplace poses its challenges. The common thread through history seems to be attempts to enhance the workplace, to better it, to convert it into a place where people could work with a free spirit. Yet, in spite of all the attempts, one failure after the other has been recorded. In a research program that endeavoured to construe the meaningful workplace, Protestant ethic was identified as one possible contributory towards such an ideal. This article explores the contribution of Protestant ethic as a contributory and sets it within the framework of universal individual values pertaining to work and work-specific values. The article also indicates that the Protestant ethic can indeed contribute towards a meaningful experience whilst performing work-related tasks in workspace. The Protestant work ethic is more than a cultural norm that places a positive moral value on doing a good job. Based on a belief that work has intrinsic value for its own sake, it represents a value system that contributes to the experience of meaningfulness whilst performing work.

  18. Neural crest contributions to the lamprey head

    Science.gov (United States)

    McCauley, David W.; Bronner-Fraser, Marianne

    2003-01-01

    The neural crest is a vertebrate-specific cell population that contributes to the facial skeleton and other derivatives. We have performed focal DiI injection into the cranial neural tube of the developing lamprey in order to follow the migratory pathways of discrete groups of cells from origin to destination and to compare neural crest migratory pathways in a basal vertebrate to those of gnathostomes. The results show that the general pathways of cranial neural crest migration are conserved throughout the vertebrates, with cells migrating in streams analogous to the mandibular and hyoid streams. Caudal branchial neural crest cells migrate ventrally as a sheet of cells from the hindbrain and super-pharyngeal region of the neural tube and form a cylinder surrounding a core of mesoderm in each pharyngeal arch, similar to that seen in zebrafish and axolotl. In addition to these similarities, we also uncovered important differences. Migration into the presumptive caudal branchial arches of the lamprey involves both rostral and caudal movements of neural crest cells that have not been described in gnathostomes, suggesting that barriers that constrain rostrocaudal movement of cranial neural crest cells may have arisen after the agnathan/gnathostome split. Accordingly, neural crest cells from a single axial level contributed to multiple arches and there was extensive mixing between populations. There was no apparent filling of neural crest derivatives in a ventral-to-dorsal order, as has been observed in higher vertebrates, nor did we find evidence of a neural crest contribution to cranial sensory ganglia. These results suggest that migratory constraints and additional neural crest derivatives arose later in gnathostome evolution.

  19. The contributions of Marcel Proust to psychoanalysis.

    Science.gov (United States)

    Bernstein, Anne Elayne

    2005-01-01

    This article is about the major contribution of Marcel Proust to psychoanalysis in his seven-part novel, A La Rècherche Du Temps Perdu (translated as Rembrance of Things Past, 1934). This work spans two decades, from 1988, when Proust writing to 1927, when the last part was published 5 years after his death. Proust, a literary scholar whose knowledge dated to the early Greeks, knew nothing of Freud or psychoanalysis. His major contributions were to the emergence of memory, specifically the exquisite details of the descriptive unconscious, which we can now explain in cognitive neuroscientific terms. Freud wanted to do this for all mental processes in 'The Project'. Proust contributed to the projective aspects of passionate love. Kernberg has pointed out that although psychoanalysts knew about transference love, idealization, and sex, love has only been a subject for us in the 1900s. Proust also wrote of jealousy as a necessary concomitant of love. He proposed that all humans had pluripotential sexuality and recognized the psychodynamics of the perversions in a way that is closer to modern psychoanalysts like Chassuguet-Smirgel. Proust was himself psychologically disabled, with an illness his father called neurasthenia, adding somatic components and abulia, inability to make decisions. We would probably recognize him today as having a borderline personality disorder, with superior cognition, depression, somatization, obsessions, compulsions, phobias, and severe anxiety, which he understood was the result of his inability to separate from his mother. Proust's findings in all these areas are compared with the psychoanalytic literature--Freud, to the present.

    Javor, Andrija; Koller, Monika; Lee, Nick; Chamberlain, Laura; Ransmayr, Gerhard

    2013-02-06

    'Neuromarketing' is a term that has often been used in the media in recent years. These public discussions have generally centered around potential ethical aspects and the public fear of negative consequences for society in general, and consumers in particular. However, positive contributions to the scientific discourse from developing a biological model that tries to explain context-situated human behavior such as consumption have often been neglected. We argue for a differentiated terminology, naming commercial applications of neuroscientific methods 'neuromarketing' and scientific ones 'consumer neuroscience'. While marketing scholars have eagerly integrated neuroscientific evidence into their theoretical framework, neurology has only recently started to draw its attention to the results of consumer neuroscience. In this paper we address key research topics of consumer neuroscience that we think are of interest for neurologists; namely the reward system, trust and ethical issues. We argue that there are overlapping research topics in neurology and consumer neuroscience where both sides can profit from collaboration. Further, neurologists joining the public discussion of ethical issues surrounding neuromarketing and consumer neuroscience could contribute standards and experience gained in clinical research. We identify the following areas where consumer neuroscience could contribute to the field of neurology:First, studies using game paradigms could help to gain further insights into the underlying pathophysiology of pathological gambling in Parkinson's disease, frontotemporal dementia, epilepsy, and Huntington's disease.Second, we identify compulsive buying as a common interest in neurology and consumer neuroscience. Paradigms commonly used in consumer neuroscience could be applied to patients suffering from Parkinson's disease and frontotemporal dementia to advance knowledge of this important behavioral symptom.Third, trust research in the medical context lacks

    This article reviews the psychosocial variables, which are of interest in the relationship between the patient and the physician. According to a classical model of social psychology, such a relationship might contribute to the placebo/nocebo effects. We develop herein various relational and contextual variables, taking into account four dimensions (intra-individual, interpersonal, positional and ideological) and their potential effects on therapeutic responses. This applies both in the setting of daily clinical practice and of clinical trials. The placebo effect offers an opportunity for collaboration and dialogue between social scientists and physicians.

    The author questions Ghilarov's (2003) claim that Darwinism has high explanatory power in ecology. He is agree with S.V. Meyen who believed that beside synthetic theory of evolution (the popular variant on Darwinism) other explanations of evolution are possible. It is emphasized that several processes (e.g., diversification and unification of species at one trophic level, as well as individual and diffusive coadaptations of species of different levels) can contribute to community evolution. Communities cannot be considered as units of natural selection.

    2011-09-01

    Full Text Available This paper presents the contributions that researches from Ethology and Evolutive Psychology can bring to Gerontology. From this perspective, human behavior may be understood under the light of Natural Selection. Thus, it is extremely important to consider how society and environment during human evolution were. This comprehension may facilitate the knowledge about how the mind and human society work, and may help to build a modern environment more similar to that of our ancestors. This paper introduces examples of evolutionary researches related to important aspects for gerontology, such as bereavement, depression and the role of grandmothers for raising children.

  7. Contributions of anterior cingulate cortex to behaviour.

    Assessments of anterior cingulate cortex in experimental animals and humans have led to unifying theories of its structural organization and contributions to mammalian behaviour. The anterior cingulate cortex forms a large region around the rostrum of the corpus callosum that is termed the anterior executive region. This region has numerous projections into motor systems, however, since these projections originate from different parts of anterior cingulate cortex and because functional studies have shown that it does not have a uniform contribution to brain functions, the anterior executive region is further subdivided into 'affect' and 'cognition' components. The affect division includes areas 25, 33 and rostral area 24, and has extensive connections with the amygdala and periaqueductal grey, and parts of it project to autonomic brainstem motor nuclei. In addition to regulating autonomic and endocrine functions, it is involved in conditioned emotional learning, vocalizations associated with expressing internal states, assessments of motivational content and assigning emotional valence to internal and external stimuli, and maternal-infant interactions. The cognition division includes caudal areas 24' and 32', the cingulate motor areas in the cingulate sulcus and nociceptive cortex. The cingulate motor areas project to the spinal cord and red nucleus and have premotor functions, while the nociceptive area is engaged in both response selection and cognitively demanding information processing. The cingulate epilepsy syndrome provides important support of experimental animal and human functional imaging studies for the role of anterior cingulate cortex in movement, affect and social behaviours. Excessive cingulate activity in cases with seizures confirmed in anterior cingulate cortex with subdural electrode recordings, can impair consciousness, alter affective state and expression, and influence skeletomotor and autonomic activity.

    Schnurrenberger, D. W.

    2001-12-01

    Kerry Kelts' dream for a new field of geology, entitled Limnogeology, sprang from his fervent belief that lakes could provide continental paleorecords of equal, if not greater, sensitivity and precision than marine paleorecords. To that end he devoted his professional life to nurturing limnogeology into a mature field of geoscience. He made contributions and encouraged others to study modern systems, paleorecords from extant basins and paleorecords from fossil lacustrine systems. To really contribute to the study of past environment and climate, Kerry realized that there were three crucial areas that needed development; new systems for retrieving high-quality sediment cores from a variety of basin types, new techniques and methods for core analyses, and the development of an infrastructure to curate lacustrine sediment cores. Kerry made major contributions in the first area with his development of a mobile, Kullenberg-type coring system and his untiring efforts that led to the construction and successful deployment of the GLAD800 coring system. Although significantly more expensive to operate than traditional lake-coring systems, these new systems opened new vistas for lake coring and provided more and higher quality sediment cores: "there's nothing cheaper than the best" (KRK). Kerry made numerous contributions in the area of core analysis ranging from his insistence on exhaustive core descriptions and documentation to his pioneering work with lacustrine isotopes (oxygen, carbon, strontium). His papers on carbonate sedimentation are required reading for aspiring Limnogeologists today. Finally, near the end of his life, Kerry saw the achievement of the final piece of the puzzle with the opening of the National Lacustrine Core Repository at the University of Minnesota. This archive serves as a testament to Kerry's idea of "generous science" and will develop into a major resource for limnogeology. Other centers are spinning off throughout the globe, in part

    2014-11-01

    Joseph Babinski (1857-1932) was an excellent clinician. André Breton, a French poet, described Babinski's way of clinical examination in his Manifeste du surréalisme (1924), which vividly revealed Babinski's meticulous character. Babinski is well known by his eponymous Babinski reflex. Although some predecessors had described this phenomenon briefly, its meaning was interpreted by Babinski. His contribution to neurological symptomatology was not restricted to his plantar skin reflex, but also to other wide area. In this article, symptoms described by Babinski, i.e. plantar skin reflex, cerebellar symptoms including cerebellar asynergy, adiadochokinesis, dysmetria, cerebellar catalepsy, and rising sign, platysma sign, anosognosia are explained and are critically discussed.

    2009-11-01

    Animal experimentation is of considerable importance in pharmacology and cannot yet be avoided when studying complex, highly integrated physiological functions. The use of animals has been drastically reduced in the classical phases of pharmacological research, for example when comparing several compounds belonging to the same pharmacological class. However, animal experiments remain crucial for generating and validating new therapeutic concepts. Three examples of such research, conducted in strict ethical conditions, will be used to illustrate the different ways in which animal experimentation has contributed to human therapeutics.

    2016-02-01

    From a critical study of our present universe it is found that dark energy, and of course, dark matter are there in the universe from the beginning of its evolution manifesting in one form or the other. The different forms contained in our model are found to be generalized Chaplygin gas, quintessence and phantom energy; of course, the generalized Chaplygin gas can explain the origin of dark energy as well as dark matter in our universe simultaneously. However the more beauty in our study is that there is high possibility of the energy produced from the neutrinos might contribute to the dark energy prevalent in this universe.

    2017-01-01

    At many hospitals, including Robert Wood Johnson (RWJ) University Hospital Rahway, librarians facilitate continuing medical education (CME) programs, sometimes working in that capacity as much as in their traditional librarian functions such as reference, research, cataloging, and bibliographic instruction. This column traces the relationship between the two aspects of the RWJ Rahway's CME coordinator and health sciences librarian's job to demonstrate that, because of their duties and skills, medical librarians can meaningfully contribute to hospitals' CME programs. The worlds of librarianship and CME are further connected by the same goal: the dissemination of information.

    Full Text Available Young drivers are the group of drivers most likely to crash. There are a number of factors that contribute to the high crash risk experienced by these drivers. While some of these factors are intrinsic to the young driver, such as their age, gender or driving skill, others relate to social factors and when and how often they drive. This article reviews the factors that affect the risk of young drivers crashing to enable a fuller understanding of why this risk is so high in order to assist in developing effective countermeasures.

  18. Glial cell contributions to auditory brainstem development

    2016-10-01

    Full Text Available Glial cells, previously thought to have generally supporting roles in the central nervous system, are emerging as essential contributors to multiple aspects of neuronal circuit function and development. This review focuses on the contributions of glial cells to the development of specialized auditory pathways in the brainstem. These pathways display specialized synapses and an unusually high degree of precision in circuitry that enables sound source localization. The development of these pathways thus requires highly coordinated molecular and cellular mechanisms. Several classes of glial cells, including astrocytes, oligodendrocytes, and microglia, have now been explored in these circuits in both avian and mammalian brainstems. Distinct populations of astrocytes are found over the course of auditory brainstem maturation. Early appearing astrocytes are associated with spatial compartments in the avian auditory brainstem. Factors from late appearing astrocytes promote synaptogenesis and dendritic maturation, and astrocytes remain integral parts of specialized auditory synapses. Oligodendrocytes play a unique role in both birds and mammals in highly regulated myelination essential for proper timing to decipher interaural cues. Microglia arise early in brainstem development and may contribute to maturation of auditory pathways. Together these studies demonstrate the importance of non-neuronal cells in the assembly of specialized auditory brainstem circuits.

    Full Text Available Obesity, a global epidemic of the modern era, is a risk factor for cardiovascular diseases (CVD and diabetes. The pervasiveness of obesity and overweight in both developed as well as developing populations is on the rise and placing a huge burden on health and economic resources. Consequently, research to control this emerging epidemic is of utmost importance. Recently, host interactions with their resident gut microbiota (GM have been reported to be involved in the pathogenesis of many metabolic diseases, including obesity, diabetes, and CVD. Around 1014 microorganisms reside within the lower human intestine and many of these 1014microorganisms have developed mutualistic or commensal associations with the host and actively involved in many physiological processes of the host. However, dysbiosis (altered gut microbial composition with other predisposing genetic and environmental factors, may contribute to host metabolic disorders resulting in many ailments. Therefore, delineating the role of GM as a contributing factor to obesity is the main objective of this review.Obesity research, as a field is expanding rapidly due to major advances in nutrigenomics, metabolomics, RNA silencing, epigenetics and other disciplines that may result in the emergence of new technologies and methods to better interpret causal relationships between microbiota and obesity.

  20. The contribution of adhesion signaling to lactogenesis.

    Morrison, Bethanie; Cutler, Mary Lou

    2010-10-01

    The mammary gland undergoes hormonally controlled cycles of pubertal maturation, pregnancy, lactation, and involution, and these processes rely on complex signaling mechanisms, many of which are controlled by cell-cell and cell-matrix adhesion. The adhesion of epithelial cells to the extracellular matrix initiates signaling mechanisms that have an impact on cell proliferation, survival, and differentiation throughout lactation. The control of integrin expression on the mammary epithelial cells, the composition of the extracellular matrix and the presence of secreted matricellular proteins all contribute to essential adhesion signaling during lactogenesis. In vitro and in vivo studies, including the results from genetically engineered mice, have shed light on the regulation of these processes at the cell and tissue level and have led to increased understanding of the essential signaling components that are regulated in temporal and cell specific manner during lactogenesis. Recent studies suggest that a secreted matricellular protein, CTGF/CCN2, may play a role in lactogenic differentiation through binding to β1 integrin complexes, enhancing the production of extracellular matrix components and contributions to cell adhesion signaling.

  1. What causes autism? Exploring the environmental contribution.

    Science.gov (United States)

    Landrigan, Philip J

    2010-04-01

    Autism is a biologically based disorder of brain development. Genetic factors--mutations, deletions, and copy number variants--are clearly implicated in causation of autism. However, they account for only a small fraction of cases, and do not easily explain key clinical and epidemiological features. This suggests that early environmental exposures also contribute. This review explores this hypothesis. Indirect evidence for an environmental contribution to autism comes from studies demonstrating the sensitivity of the developing brain to external exposures such as lead, ethyl alcohol and methyl mercury. But the most powerful proof-of-concept evidence derives from studies specifically linking autism to exposures in early pregnancy - thalidomide, misoprostol, and valproic acid; maternal rubella infection; and the organophosphate insecticide, chlorpyrifos. There is no credible evidence that vaccines cause autism. Expanded research is needed into environmental causation of autism. Children today are surrounded by thousands of synthetic chemicals. Two hundred of them are neurotoxic in adult humans, and 1000 more in laboratory models. Yet fewer than 20% of high-volume chemicals have been tested for neurodevelopmental toxicity. I propose a targeted discovery strategy focused on suspect chemicals, which combines expanded toxicological screening, neurobiological research and prospective epidemiological studies.

  2. A Contribution Towards A Grammar of Code

    Directory of Open Access Journals (Sweden)

    David M. Berry

    2008-01-01

    Full Text Available Over the past thirty years there has been an increasing interest in the social and cultural implications of digital technologies and ‘informationalism’ from the social sciences and humanities. Generally this has concentrated on the implications of the “convergence” of digital devices and services, understood as linked to the discrete processing capabilities of computers, which rely on logical operations, binary processing and symbolic representation. In this paper, I wish to suggest that a ‘grammar of code’ might provide a useful way of thinking about the way in which digital technologies operate as a medium and can contribute usefully to this wider debate. I am interested in the way in which the dynamic properties of code can be understood as operating according to a grammar reflected in its materialisation and operation in the lifeworld – the discretisation of the phenomenal world. As part of that contribution in this paper I develop some tentative Weberian ‘ideal-types’. These ideal-types are then applied to the work of the Japanese composer, Masahiro Miwa, whose innovative ‘Reverse-Simulation music’ models the operation of basic low-level digital circuitry for the performance and generation of musical pieces.

    It has been realised that corners in entangling surfaces can induce new universal contributions to the entanglement entropy and Rényi entropy. In this paper we study universal corner contributions to entanglement negativity in three- and four-dimensional CFTs using both field theory and holographic techniques. We focus on the quantity χ defined by the ratio of the universal part of the entanglement negativity over that of the entanglement entropy, which may characterise the amount of distillable entanglement. We find that for most of the examples χ takes bigger values for singular entangling regions, which may suggest increase in distillable entanglement. However, there also exist counterexamples where distillable entanglement decreases for singular surfaces. We also explore the behaviour of χ as the coupling varies and observe that for singular entangling surfaces, the amount of distillable entanglement is mostly largest for free theories, while counterexample exists for free Dirac fermion in three dimensions. For holographic CFTs described by higher derivative gravity, χ may increase or decrease, depending on the sign of the relevant parameters. Our results may reveal a more profound connection between geometry and distillable entanglement.

    2013-12-01

    Many studies have shown that mass redistribution within the oceans and ocean currents are significant contributors to polar motion. Chambers and Willis (2009) have previously identified a significant low-frequency mass exchange between the Pacific and Indo-Atlantic Oceans. Here, we examine how much this large-scale mass exchange contributes to polar motion by using ocean bottom pressure data from a model for 1993 to 2011. We find that the interbasin exchange of mass explains nearly 53% of the y-component of polar motion driven by ocean mass variations, but less than 3% the x-component. On the other hand, redistribution of mass within the Pacific alone explains nearly 60% of the variance in the x-component driven by ocean mass variations. The remainder of the variance is explained by redistribution within the Indo-Atlantic Ocean. The motion component of polar motion based on currents from the same model was also calculated using only data from areas poleward of of 30°S to the contribution of the Antarctic Circumpolar Current on polar motion.

  8. Contributions to In Silico Genome Annotation

    KAUST Repository

    Kalkatawi, Manal M.

    2017-11-30

    Genome annotation is an important topic since it provides information for the foundation of downstream genomic and biological research. It is considered as a way of summarizing part of existing knowledge about the genomic characteristics of an organism. Annotating different regions of a genome sequence is known as structural annotation, while identifying functions of these regions is considered as a functional annotation. In silico approaches can facilitate both tasks that otherwise would be difficult and timeconsuming. This study contributes to genome annotation by introducing several novel bioinformatics methods, some based on machine learning (ML) approaches. First, we present Dragon PolyA Spotter (DPS), a method for accurate identification of the polyadenylation signals (PAS) within human genomic DNA sequences. For this, we derived a novel feature-set able to characterize properties of the genomic region surrounding the PAS, enabling development of high accuracy optimized ML predictive models. DPS considerably outperformed the state-of-the-art results. The second contribution concerns developing generic models for structural annotation, i.e., the recognition of different genomic signals and regions (GSR) within eukaryotic DNA. We developed DeepGSR, a systematic framework that facilitates generating ML models to predict GSR with high accuracy. To the best of our knowledge, no available generic and automated method exists for such task that could facilitate the studies of newly sequenced organisms. The prediction module of DeepGSR uses deep learning algorithms to derive highly abstract features that depend mainly on proper data representation and hyperparameters calibration. DeepGSR, which was evaluated on recognition of PAS and translation initiation sites (TIS) in different organisms, yields a simpler and more precise representation of the problem under study, compared to some other hand-tailored models, while producing high accuracy prediction results.

  9. Why did employee health insurance contributions rise?

    Gruber, Jonathan; McKnight, Robin

    2003-11-01

    We explore the causes of the dramatic rise in employee contributions to health insurance over the past two decades. In 1982, 44% of those who were covered by their employer-provided health insurance had their costs fully financed by their employer, but by 1998 this had fallen to 28%. We discuss the theory of why employers might shift premiums to their employees, and empirically model the role of four factors suggested by the theory. We find that there was a large impact of falling tax rates, rising eligibility for insurance through the Medicaid system, rising medical costs, and increased managed care penetration. Overall, this set of factors can explain more than one-half of the rise in employee premiums over the 1982-1996 period.

    Steponas Kolupaila (1892-1964) was an important figure in 20th century hydrology and one of the pioneers of scientific water gauging in Europe. His research on the reliability of hydrological data and measurement methods was particularly important and contributed to the development of empirical hydrological calculation methods. Kolupaila was one of the first who standardised water-gauging methods internationally. He created several original hydrological and hydraulic calculation methods (his discharge assessment method for winter period was particularly significant). His innate abilities and frequent travel made Kolupaila a universal specialist in various fields and an active public figure. He revealed his multilayered scientific and cultural experiences in his most famous book, Bibliography of Hydrometry. This book introduced the unique European hydrological-measurement and computation methods to the community of world hydrologists at that time and allowed the development and adaptation of these methods across the world.

    Full Text Available The paper deals with the EU aid concerning to improved the economic situation from developing countries. Therefore, the aim of this research is to identify how EU states contribute to helping poor countries, members of the World Trade Organization. For the beginning, we define the EU’position before, during and after the Doha Round – a round of WTO multilateral trade negotiations. Moreover, we analyse the development dimension, focusing on countries „marginalized” until early of XXI century in terms of international trade, because this represents the idea-axis of the Doha Round. In this context, the EU – one of the leading global commercial players and a key member of the institution mentioned above – has set several objectives to achieve the basic goal of negotiations and several ways to support developing countries. To conclude, we propose to define the key points of the European aid for least developed and developing countries.

    2006-05-01

    Many of Meehl's interests converged in his work on personality assessment. In empirical research, development of the K scale of the Minnesota Multiphasic Personality Inventory and various scales of other tests are noteworthy, but his most profound contributions were conceptual and philosophical. Essays on the role of base rates in clinical decision and on construct validity in psychological tests provided vital insights on core issues in assessment. The concept of nomological nets allowed systematic investigation of unobservable theoretical entities, with liberating effects on all natural sciences. An active clinician, Meehl understood deeply the complexities of professional service, but his insistence on empirical validation as the ultimate arbiter of the value of any procedure required all attainable rigor in the scientific foundations of clinical practice.

    2006-05-01

    Paul E. Meehl's work on the clinical versus statistical prediction controversy is reviewed. His contributions included the following: putting the controversy center stage in applied psychology; clarifying concepts underpinning the debate (especially his crucial distinction between ways of gathering data and ways of combining them) as well as establishing that the controversy was real and not concocted, analyzing clinical inference from both theoretical and probabilistic points of view, and reviewing studies that compared the accuracy of these 2 methods of data combination. Meehl's (1954/1996) conclusion that statistical prediction consistently outperforms clinical judgment has stood up extremely well for half a century. His conceptual analyses have not been significantly improved since he published them in the 1950s and 1960s. His work in this area contains several citation classics, which are part of the working knowledge of all competent applied psychologists today.

    Full Text Available This contribution is dealing with more than up to date topic. Nowadays more than one third of human population suffers from some form of allergies – dust, pollen or mites. The air we breathe the whole day does not come from outside, on the contrary it comes from closed rooms used for living. the important part of air are the negative ions which are neccessary for life. Therefore, the optimal level of ions should be maintained. Living enviroment which does not contain enough negative ions causes various diseases, such as allergies, asthma, headache, tiredness and depressions. Increased concentration of negative ions inside a house is the basic prevention of tiredness and other diseases.

    2014-04-01

    Full Text Available The main objective of this paper is to present the importance of hysteria on Babinski's oeuvre, and the conceptions of pithiatism from Babinski until the one of conversion disorder. Babinski gave a mental basis for hysteria in the place of Charcot's encephalopatic one, and several important semiotic tools to differentiate organic from hysterical manifestations based on studies from 1893-1917/8. His teachings were spread worldwide, and in Brazil they were also appreciated in the work on hysteria by Antonio Austregesilo, the first Brazilian neurology chairman. The neurobiological basis of hysteria conceived by Charcot is nowadays reappraised, and Babinski's neurosemiological contribution is everlasting. The patients believed to be hysterical, and the two outstanding neurologists, Charcot and Babinski, gave support for the development of the modern neurology.

    The analysis of ancient artefacts is a long but largely neglected thread within the histories of archaeology and chemistry. This paper examines Michael Faraday's contributions to this nascent field, drawing on his published correspondence and the works of his antiquarian collaborators, and focusing in particular on his analyses of Romano-British and ancient Egyptian artefacts. Faraday examined the materials used in ancient Egyptian mummification, and provided the first proof of the use of lead glazes on Roman ceramics. Beginning with an assessment of Faraday's personal interests and early work on antiquities with Humphry Davy, this paper critically examines the historiography of archaeological chemistry and attempts to place Faraday's work within its institutional, intellectual, and economic contexts.

  18. Contribution of neutrophils to acute lung injury.

    Grommes, Jochen; Soehnlein, Oliver

    2011-01-01

    Treatment of acute lung injury (ALI) and its most severe form, acute respiratory distress syndrome (ARDS), remain unsolved problems of intensive care medicine. ALI/ARDS are characterized by lung edema due to increased permeability of the alveolar-capillary barrier and subsequent impairment of arterial oxygenation. Lung edema, endothelial and epithelial injury are accompanied by an influx of neutrophils into the interstitium and broncheoalveolar space. Hence, activation and recruitment of neutrophils are regarded to play a key role in progression of ALI/ARDS. Neutrophils are the first cells to be recruited to the site of inflammation and have a potent antimicrobial armour that includes oxidants, proteinases and cationic peptides. Under pathological circumstances, however, unregulated release of these microbicidal compounds into the extracellular space paradoxically can damage host tissues. This review focuses on the mechanisms of neutrophil recruitment into the lung and on the contribution of neutrophils to tissue damage in ALI.

  19. Three contributions to robust regression diagnostics

    Directory of Open Access Journals (Sweden)

    Kalina J.

    2015-12-01

    Full Text Available Robust regression methods have been developed not only as a diagnostic tool for standard least squares estimation in statistical and econometric applications, but can be also used as self-standing regression estimation procedures. Therefore, they need to be equipped by their own diagnostic tools. This paper is devoted to robust regression and presents three contributions to its diagnostic tools or estimating regression parameters under non-standard conditions. Firstly, we derive the Durbin-Watson test of independence of random regression errors for the regression median. The approach is based on the approximation to the exact null distribution of the test statistic. Secondly, we accompany the least trimmed squares estimator by a subjective criterion for selecting a suitable value of the trimming constant. Thirdly, we propose a robust version of the instrumental variables estimator. The new methods are illustrated on examples with real data and their advantages and limitations are discussed.

  20. Contribution of muscle proteinases to meat tenderization.

    Jiang, S T

    1998-07-01

    The exact mechanisms involved in the postmortem meat tenderization process and the nature of changes associated with improvement in tenderness are complex and not fully understood. Based on the relevant evidence thus far obtained, the focus of this review is on clarifying the factors affecting meat tenderness, particularly the toughening and tenderness phases, possible endogenous proteinases involved in meat tenderization and how these proteinases contribute to meat tenderization. Of the different biochemical and ultrastructural changes occurring in the meat tenderization process, myofibril disruption at the Z-disk and contractile proteins are discussed in detail. This myofibril disruption can perhaps be ascribed to the synergistic action of calcium-dependent proteinases (both mu- and m-calpains) and lysosomal proteinases, especially the cathepsins B and L.

    Full Text Available To continuously and systematically improve efficiency and efficacy of processes, organizations need the implication of all employees in continuous improvement and innovation through suitable Quality Management Programs (QMPs. Effectiveness of these programs is directly linked to the requirement employees understand the methodologies and tools used for QM and the benefits that will derivate from their implementation, individually and collectively, so they can commit and implicate. Lean Management is a friendly methodology to continuously and systematically achieve process improvement, so helping the organization seeking operational excellence that contributes to overall excellence. This paper identifies Critical Success Factors (CSFs for an effective implementation of QMPs, suggests Lean Management as an easy-to-understand, powerful and friendly methodology for operational excellence and overall excellence, and presents a case experience of implementation of Lean Management in a health care organization that applies the EFQM model, and the lessons learnt.

  3. Rapidly moving contact lines and damping contributions

    Xia, Yi; Daniel, Susan; Steen, Paul

    2017-11-01

    Contact angle varies dynamically with contact line (CL) speed when a liquid moves across a solid support, as when a liquid spreads rapidly. For sufficiently rapid spreading, inertia competes with capillarity to influence the interface shape near the support. We use resonant-mode plane-normal support oscillations of droplets to drive lateral contact-line motion. Reynolds numbers based on CL speeds are high and capillary numbers are low. These are inertial-capillary motions. By scanning the driving frequency, we locate the frequency at peak amplification (resonance), obtain the scaled peak height (amplification factor) and a measure of band-width (damping ratio). We report how a parameter for CL mobility depends on these scanning metrics, with the goal of distinguishing contributions from the bulk- and CL-dissipation to overall damping.

    In the framework of the quark-diquark model of baryons, Λ b can be considered as b constituent quark an ud constituent diquark. In this study, we investigate the effect ud scalar diquark fragmentation into Λ b , therefor we calculate frgmentation functions of b quark and ud diquark into Λ b baryon through the use of perturbative QCD. In the next stage, throuth the use of the obtained fragmentation functions, we calculate the total fragmentation probabilities and average fragmentation parameters for b→Λ b and u d→Λ b . Finally, the inclusive cross section of Λ b baryon in electron-positron annihilation in ALEPH experiment is calculated with regard to ud diquark fragmentation contribution.

    Thomas Jefferson, the third president of the United States and author of the Declaration of Independence, had a consuming interest in all fields of education and science, including the practice of medicine and public health. He actively developed medical education, supported measures for public health, and encouraged scientific research supported by the government without policy intervention. Although a close friend of eminent physicians, his rationalism and scientific method placed him ahead of many practitioners of his time. He disparaged medical quackery but actively supported therapies such as vaccination that were based on research and careful observation. The School of Medicine at the University of Virginia was Jefferson's concrete contribution to the advancement of medical education in the United States and epitomized his preoccupation with medicine and science as important cornerstones of a healthy American nation.

    The EXIST Mission is a proposed multi-wavelength observatory to carry out the most sensitive hard X-ray survey and census of SMBH as well as the most powerful follow-up of Gamma Ray Bursts (GRBs). This mission will carry a large area (4.5m2) CdZnTe modular detector with an angular resolution of ˜2arcmin, sensitive in the energy range 5-600 keV, and a near infrared telescope with cooled mirror with outstanding sensitivity and capability of measuring onboard the redshift of many GRBs. Italy will contribute to EXIST with the provision of a soft X-ray telescope sensitive in the energy range 0.1-10 keV with an effective area approximately equivalent to one mirror module of XMM-Newton. We will describe hereafter the characteristics and performance of this instrument together with its capability of performing serendipitous surveys.

    Pharmacovigilance activities have been ongoing for 4 decades. However, little is known (especially outside of the area) about the contribution of Latin America to this field. To review and quantify the published literature on pharmacovigilance in Latin American countries. We searched electronic databases including MEDLINE (1966-2004), EMBASE (1980-2004), International Pharmaceutical Abstracts (1970-2004), Toxline (1992-2004), Literatura Latino-Americana e do Caribe em Ciências da Saúde (1982-2004), Sistema de Información Esencial en Terapéutica y Salud (1980-2004), and the Pan American Health Organization Web site (1970-2004) for articles on pharmacovigilance or adverse drug reactions in any of the 19 major Latin American countries. Papers were retrieved and categorized according to content and country of origin by 2 independent reviewers. There were 195 usable articles from 13 countries. Fifty-one of the papers retrieved dealt with pharmacovigilance centers (15 national centers, 10 hospitals, 26 other), 55 covered pharmacovigilance itself (21 theoretical papers, 9 with description of models, 25 educational papers), and 89 were pharmacoepidemiologic studies of adverse drug reactions (69 case reports, 13 observational cohorts, 2 cohort studies, 1 randomized clinical trial, 4 clinical papers on adverse reaction management). Studies have increased exponentially since 1980. Five countries (Argentina, Brazil, Chile, Costa Rica, Venezuela) published reports from national centers. No studies were found from 6 countries: Dominican Republic, El Salvador, Honduras, Nicaragua, Paraguay, or Uruguay. Most studied categories were antiinfectives and drugs affecting the central nervous system, cardiovascular system, and musculoskeletal system. Contributions of Latin American countries to the field of pharmacovigilence have been remarkable, considering the constraints on these countries. A need exists for an increased number of formal pharmacovigilance studies and research

  9. Contribution of Donana wetlands to carbon sequestration.

    Directory of Open Access Journals (Sweden)

    Edward P Morris

    Full Text Available Inland and transitional aquatic systems play an important role in global carbon (C cycling. Yet, the C dynamics of wetlands and floodplains are poorly defined and field data is scarce. Air-water CO2 fluxes in the wetlands of Doñana Natural Area (SW Spain were examined by measuring alkalinity, pH and other physiochemical parameters in a range of water bodies during 2010-2011. Areal fluxes were calculated and, using remote sensing, an estimate of the contribution of aquatic habitats to gaseous CO2 transport was derived. Semi-permanent ponds adjacent to the large Guadalquivir estuary acted as mild sinks, whilst temporal wetlands were strong sources of CO2 (-0.8 and 36.3 mmol(CO2 m(-2 d(-1. Fluxes in semi-permanent streams and ponds changed seasonally; acting as sources in spring-winter and mild sinks in autumn (16.7 and -1.2 mmol(CO2 m(-2 d(-1. Overall, Doñana's water bodies were a net annual source of CO2 (5.2 mol(C m(-2 y(-1. Up-scaling clarified the overwhelming contribution of seasonal flooding and allochthonous organic matter inputs in determining regional air-water gaseous CO2 transport (13.1 Gg(C y(-1. Nevertheless, this estimate is about 6 times < local marsh net primary production, suggesting the system acts as an annual net CO2 sink. Initial indications suggest longer hydroperiods may favour autochthonous C capture by phytoplankton. Direct anthropogenic impacts have reduced the hydroperiod in Doñana and this maybe exacerbated by climate change (less rainfall and more evaporation, suggesting potential for the modification of C sequestration.

    Background and Purpose This scientific statement provides an overview of the evidence on vascular contributions to cognitive impairment and dementia. Vascular contributions to cognitive impairment and dementia of later life are common. Definitions of vascular cognitive impairment (VCI), neuropathology, basic science and pathophysiological aspects, role of neuroimaging and vascular and other associated risk factors, and potential opportunities for prevention and treatment are reviewed. This statement serves as an overall guide for practitioners to gain a better understanding of VCI and dementia, prevention, and treatment. Methods Writing group members were nominated by the writing group co-chairs on the basis of their previous work in relevant topic areas and were approved by the American Heart Association Stroke Council Scientific Statement Oversight Committee, the Council on Epidemiology and Prevention, and the Manuscript Oversight Committee. The writing group used systematic literature reviews (primarily covering publications from 1990 to May 1, 2010), previously published guidelines, personal files, and expert opinion to summarize existing evidence, indicate gaps in current knowledge, and, when appropriate, formulate recommendations using standard American Heart Association criteria. All members of the writing group had the opportunity to comment on the recommendations and approved the final version of this document. After peer review by the American Heart Association, as well as review by the Stroke Council leadership, Council on Epidemiology and Prevention Council, and Scientific Statements Oversight Committee, the statement was approved by the American Heart Association Science Advisory and Coordinating Committee. Results The construct of VCI has been introduced to capture the entire spectrum of cognitive disorders associated with all forms of cerebral vascular brain injury—not solely stroke—ranging from mild cognitive impairment through fully developed

  13. Biomass burning contribution to Beijing aerosol

    2013-08-01

    Full Text Available Biomass burning, the largest global source of elemental carbon (EC and primary organic carbon (OC, is strongly associated with many subjects of great scientific concern, such as secondary organic aerosol and brown carbon which exert important effects on the environment and on climate in particular. This study investigated the relationships between levoglucosan and other biomass burning tracers (i.e., water soluble potassium and mannosan based on both ambient samples collected in Beijing and source samples. Compared with North America and Europe, Beijing was characterized by high ambient levoglucosan concentrations and low winter to summer ratios of levoglucosan, indicating significant impact of biomass burning activities throughout the year in Beijing. Comparison of levoglucosan and water soluble potassium (K+ levels suggested that it was acceptable to use K+ as a biomass burning tracer during summer in Beijing, while the contribution of fireworks to K+ could be significant during winter. Moreover, the levoglucosan to K+ ratio was found to be lower during the typical summer period (0.21 ± 0.16 compared with the typical winter period (0.51 ± 0.15. Levoglucosan correlated strongly with mannosan (R2 = 0.97 throughout the winter and the levoglucosan to mannosan ratio averaged 9.49 ± 1.63, whereas levoglucosan and mannosan exhibited relatively weak correlation (R2 = 0.73 during the typical summer period when the levoglucosan to mannosan ratio averaged 12.65 ± 3.38. Results from positive matrix factorization (PMF model analysis showed that about 50% of the OC and EC in Beijing were associated with biomass burning processes. In addition, a new source identification method was developed based on the comparison of the levoglucosan to K+ ratio and the levoglucosan to mannosan ratio among different types of biomass. Using this method, the major source of biomass burning aerosol in Beijing was suggested to be the combustion of crop residuals, while the

    Further action is needed that goes far beyond what has been agreed so far under the United Nations Framework Convention on Climate Change (UNFCCC) and the Kyoto Protocol to 'prevent dangerous anthropogenic interference with the climate system', the ultimate objective of the UNFCCC. It is out of question that developed countries (Annex I countries) will have to take a leading role. They will have to commit to substantial emission reductions and financing commitments due to their historical responsibility and their financial capability. However, the stabilisation of the climate system will require global emissions to peak within the next decade and decline well below half of current levels by the middle of the century. It is hence a global issue and, thus, depends on the participation of as many countries as possible. This report provides a comparative analysis of greenhouse gas (GHG) emissions, including their national climate plans, of the major emitting developing countries Brazil, China, India, Mexico, South Africa and South Korea. It includes an overview of emissions and economic development, existing national climate change strategies, uses a consistent methodology for estimating emission reduction potential, costs of mitigation options, provides an estimate of the reductions to be achieved through the national climate plans and finally provides a comparison of the results to the allocation of emission rights according to different global effort-sharing approaches. In addition, the report discusses possible nationally appropriate mitigation actions (NAMAs) the six countries could take based on the analysis of mitigation options. This report is an output of the project 'Proposals for quantifying emission reduction contributions by emerging economies' by Ecofys and the Wuppertal Institute for the Federal Environment Agency in Dessau. It builds upon earlier joint work ''Proposals for contributions of emerging economies to the climate

    The nasal mucosa plays the main role as the entry and the exit of leprosy bacilli and the nasal involvement may precede the skin lesions by several years. Nasal biopsy has been used in research but its clinical application has not been described. We evaluated the contribution of the nasal biopsy for the diagnosis of leprosy and its correlation to skin biopsy and skin smear in untreated patients. We evaluated changes in nasal biopsy in 227 leprosy patients. Patients were clinically classified and skin and nasal biopsies and skin smear were performed. Nasal biopsy showed positivity in 100% of the lepromatous spectrum decreasing toward the tuberculoid (TT) pole. Patients with TT or indeterminate forms did not present any nasal alterations, showing that they are the true paucibacillary forms. Also, the nasal biopsies of two patients were the only exam to show positivity. The bacillary index of the nasal biopsy was strongly correlated to skin biopsy and slit-skin smear. Additionally, the agreement among the exams was good, revealing the reliability of the nasal biopsy in leprosy diagnosis. The present study showed a rate of 48% of positivity in nasal biopsy of untreated patients, correlating well with skin biopsy and skin smear. Thus, the method in leprosy diagnosis and clinical form classification has shown great reliability.

    1992-01-01

    OBJECTIVES: To determine the relative independent contributions of mobility and mental function to the prevalence rate of incontinence in a long-term care hospital and to establish the baseline prevalence rate and cost of incontinence before implementation of a continence program. DESIGN: Prevalence survey. SETTING: Long-term care hospital. PARTICIPANTS: All 457 inpatients (mean age of men 73.6 years, of women 73.8 years) who met the defined criteria for degree of urinary and fecal incontinence, mobility and mental function. Of the 447 questionnaires that were returned 12 were incomplete. MAIN OUTCOME MEASURES: Degree of urinary and fecal incontinence and costs of incontinence as measured by nursing time spent dealing with incontinent patients, laundry and incontinence supplies. RESULTS: The prevalence rate of urinary incontinence was 62%, fecal incontinence 46% and combined incontinence 44%. The mean time spent each day dealing with incontinence was 52.5 minutes per patient. The total annual cost of incontinence per patient was $9771. Mobility and mental function were independent predictors of frequency of urinary and fecal incontinence. Frequency of incontinent events was the strongest predictor of quantity of linen soiled, but immobility was the strongest predictor of nursing time spent dealing with incontinence. CONCLUSIONS: The prevalence rate of urinary incontinence depends on patient characteristics and the definition of incontinence. A management approach to incontinence could lower laundry and supply costs, and improvements in mobility could reduce nursing time spent dealing with incontinence. PMID:1643598

  17. Towards psychoanalytic contribution to linguistic metaphor theory.

    Caspi, Tair

    2017-07-05

    This paper lays out a formulation of the psychoanalytical contribution to linguistic metaphor theory. The author's main argument is that psychoanalysis can help enrich and shed light on linguistic metaphor theories, since these have focused on the cognitive aspect, to the exclusion of the role played by affect. Based on the tight link between metaphor and symbol - both configurations of figurative language - the author shall apply ideas sourced from some of the key psychoanalytic symbolization theories, focusing in particular on Klein, Winnicott, and Ogden. The course of exploration will serve to trace the unconscious emotional aspects that participate in the metaphor's mechanism, just as they participate in the symbol's workings. The study leads to the main conclusion that the intersubjective transitional space is of substantial importance to metaphor's constitution, particularly in regard to novel metaphors. Expanding the understanding of metaphor's modus operandi has important implications in conceptual clarification and for an in-depth analytical work, and is of immense significance when it comes to analytical work with patients who suffer impairment of their metaphoric ability.

    Cleaveland, S; Borner, M; Gislason, M

    2014-08-01

    Although One Health is widely promoted as a more effective approach towards human, animal and ecosystem health, the momentum is still driven largely by health professionals, predominantly from the veterinary sector. While few can doubt the merits of interdisciplinary One Health approaches to tackle complex health problems, operating across the disciplines still presents many challenges. This paper focuses on the contributions of partners from ecology and conservation to One Health approaches, and identifies four broad areas which could act as a focus for practical engagement and bring ecological and conservation objectives more to the forefront of the One Health agenda: i) developing initiatives with shared conservation and health objectives, particularly in and around protected areas and including programmes addressing human reproductive health and mental health; ii) broadening concepts of health to extend beyond indicators of disease to include the assessment of ecological impacts; iii) the integration of ecological and epidemiological monitoring systems within protected areas to support conservation management and wildlife disease surveillance; iv) building partnerships to bring conservation, health, development and animal welfare agencies together to combat threats to global biodiversity and health from the international trade in wildlife and wildlife products.

    Full Text Available OBJECTIVE: To evaluate the various causes of perinatal deaths and adopt strategies to improve perinatal outcome at a referral teaching hospital in North Kerala. METHODS: A prospective observational study conducted at Institute of Maternal and Child Health, Government Medical College, Kozhikode. All perinatal deaths during the period January 2013 to December 2014 were analysed and from this factors responsible for perinatal deaths were identified. RESULTS: Out of total 30,042 deliveries , there were 966 perinatal deaths during the study period. 566 were still births and 400 early neonatal deaths. The perinatal mortality rate was 31.1 per 1000 live births. Perinatal asphyxia was the major cause of perinatal mortality. The important factors contributing to perinatal asphyxia were prematurity (39%, abruptio placenta (19% and MSAF ( 12%. Among the antenatal factors, hypertensive disorders of pregnancy leading to iatrogenic elective preterm delivery were the most important. CONCLUSION: Perinatal asphyxia due to prematurity and low birth weight emerged as the most important cause of perinatal mortality in this study and hypertensive disorders of pregnancy were the most important antenatal complication leading to prematurity

    2017-12-04

    The cognitive neuroscience of aging is a young discipline that has emerged as a result of the combination of: A) the theoretical and explanatory frameworks proposed by the cognitive psychology perspective throughout the second half of the twentieth century; B) the designs and methodological procedures arising from experimental psychology and the need to test the hypotheses proposed from the cognitive psychology perspective; C) the contributions of the computer sciences to the explanation of brain functions; and D) the development and use of neuroimaging techniques that have enabled the recording of brain activity in humans while tasks that test some cognitive process or function are performed. An analysis on the impact of research conducted from this perspective over the last 3decades has been carried out, including its shortcomings, as well as the potential directions and usefulness that will advantageously continue to drive this discipline in its description and explanation of the process es of cerebral and cognitive aging.

Hardy in the Hardy-Weinberg law, pervasive in textbooks on population genetics since it expresses stability over generations of zygote frequencies AA, Aa, aa under random mating. One of Weinberg's signal contributions, in an article whose centenary we celebrate, was to verify that Mendel's segregation law still held in the setting of human heredity, contrary to the then-prevailing view of William Bateson (1861-1926), the leading Mendelian geneticist of the time. Specifically, Weinberg verified that the proportion of recessive offspring genotypes aa in human parental crossings Aa × Aa (that is, the segregation ratio for such a setting) was indeed p=1/4. We focus in a nontechnical way on his procedure, called the simple sib method, and on the heated controversy with Felix Bernstein (1878-1956) in the 1920s and 1930s over work stimulated by Weinberg's article.

    Paul Holland began his career in transfusion medicine in 1963 as an assistant to Dr. Paul Schmidt in the Blood Bank at the National Institutes of Health (NIH). He served at the NIH for 20 years and retired in 1983 with the rank of Captain in the Public Health Service. He subsequently became the Medical Director/CEO of the Sacramento Medical Foundation Blood Center, now Blood Source, a position he held for the next 21 years. Paul Holland has authored/co-authored 265 articles, chapters and monographs, mostly concerning issues relating to either viral hepatitis or HIV. In addition to his research career, Paul was a very active educator, having contributed importantly to the development of many current thought leaders in transfusion medicine. His distinguished career also included important administrative roles in national and international organizations relevant to transfusion medicine. He also was the recipient of many honors and awards which has won him wide-spread renown and the respect of his many colleagues. Copyright © 2013. Published by Elsevier Inc.

  3. Adipokine Contribution to the Pathogenesis of Osteoarthritis

    Full Text Available Recent studies have shown that overweight and obesity play an important role in the development of osteoarthritis (OA. However, joint overload is not the only risk factor in this disease. For instance, the presence of OA in non-weight-bearing joints such as the hand suggests that metabolic factors may also contribute to its pathogenesis. Recently, white adipose tissue (WAT has been recognized not only as an energy reservoir but also as an important secretory organ of adipokines. In this regard, adipokines have been closely associated with obesity and also play an important role in bone and cartilage homeostasis. Furthermore, drugs such as rosuvastatin or rosiglitazone have demonstrated chondroprotective and anti-inflammatory effects in cartilage explants from patients with OA. Thus, it seems that adipokines are important factors linking obesity, adiposity, and inflammation in OA. In this review, we are focused on establishing the physiological mechanisms of adipokines on cartilage homeostasis and evaluating their role in the pathophysiology of OA based on evidence derived from experimental research as well as from clinical-epidemiological studies.

    Death tolls in earthquakes, which continue to grow rapidly, are the result of complex interactions between physical effects, such as strong shaking, and the resilience of exposed populations and supporting critical infrastructures and institutions. While it is clear that the social context in which the earthquake occurs has a strong effect on the outcome, the influence of this context can only be exposed if we first decouple, as much as we can, the physical causes of mortality from our consideration. (Our modelling assumes that building resilience to shaking is a social factor governed by national wealth, legislation and enforcement and governance leading to reduced levels of corruption.) Here we attempt to remove these causes by statistically modelling published mortality, shaking intensity and population exposure data; unexplained variance from this physical model illuminates the contribution of socio-economic factors to increasing earthquake mortality. We find that this variance partitions countries in terms of basic socio-economic measures and allows the definition of a national vulnerability index identifying both anomalously resilient and anomalously vulnerable countries. In many cases resilience is well correlated with GDP; people in the richest countries are unsurprisingly safe from even the worst shaking. However some low-GDP countries rival even the richest in resilience, showing that relatively low cost interventions can have a positive impact on earthquake resilience and that social learning between these countries might facilitate resilience building in the absence of expensive engineering interventions.

  5. THE CONTRIBUTION OF GESTURES TO PERSONAL BRANDING

    2015-07-01

    Full Text Available A form of (self-promotion but also an authentic strategic choice, the personal brand has become a topical preoccupation of marketing specialists. Personal branding or self-marketing represents an innovative concept that associates the efficiency of personal development with the effectiveness of communication and marketing techniques adapted to the individual and that comprises the entire collection of techniques allowing the identification and promotion of the self/individual. The main objective is a clear communication with regard to personal identity, no matter by means of which method, so that it gives uniqueness and offers a competitive advantage. Although online promotion is increasingly gaining ground for the creation of a personal brand, an individual’s verbal and nonverbal behaviour represent very important differentiating elements. Starting from the premise that gestures often complement, anticipate, substitute or contradict the verbal, we will endeavour to highlight a number of significations that can be attributed to the various body movements and that can successfully contribute to the creation of a powerful personal brand.

    It is increasingly recognised that traits associated with autism reflect a spectrum with no clear boundary between typical and atypical behaviour. Dimensional traits are needed to investigate the broader autism phenotype. Ninety-three individual measures reflecting components of social, communication and repetitive behaviours characterising autistic spectrum disorder (ASD) were identified between the ages of 6 months and 9 years from the ALSPAC database. Using missing value imputation, data for 13,138 children were analysed. Factor analysis suggested the existence of 7 factors explaining 85% of the variance. The factors were labelled: verbal ability, language acquisition, social understanding, semantic-pragmatic skills, repetitive-stereotyped behaviour, articulation and social inhibition. Four factors (1, 3, 5 and 7) were specific to ASD being more strongly associated with this phenotype than other co-morbid conditions while other factors were more associated with learning difficulties and specific language impairment. Nevertheless, all 7 factors contributed independently to the explanation of ASD (porigins for these components despite pleiotropic genetic effects being observed. These traits are likely to be useful in the exploration of ASD.

    Objectives: The ortopantomography (OPG) can be a valuable way for an early detection of calcified atheroma plaques, thus contributing for a preliminary stroke risk evaluation. The study looks for the existence of calcified atheroma plates through the use of OPG, comparing the results with the stenosis percentage found through eco-doppler. It has been analyzed the correlation of the number of years as a smoker, arterial hypertension and body mass index, against the risk of having calcified atheroma plaques. Study Design: Observational, transversal and prospective study with 84 patients from the Dental Center of Hospital Particular de Lisboa. First the patients answered to an inquiry and them they were submitted to an OPG and an eco-doppler. Results and Conclusions: It is possible to detect calcified atheroma plaques in the carotid artery through an OPG and patients who have them have got a fifteen fold greater risk of suffering from carotid stenosis. In this study, it has been confirmed the increase in carotid stenosis for long term smokers (OR = 1,033, n=18, 42,9%). The study results show that hypertension patients have a probability 5,426 greater than normal of developing atheroma plaques (with sig=0,049). Amid analyzed patients, the correlation between obesity and the existence of carotid atheroma plaques was significant, although negative (sig=0,047). OPG can help find patients with higher risk of isquemic stroke. Key words:Orthopantomography, Stroke, Carotid disease, Calcified atheroma. PMID:24790711

    2010-03-01

    Full Text Available Abstract Uniparental disomy (UPD is often considered as an event to be characterized exclusively by molecular genetic or epigenetic approaches. This review shows that at least one third of UPD cases emerge in connection with or due to a chromosomal rearrangement. Thus, additional (molecular cytogenetic characterization of UPD cases is essential. Up to now > 1,100 UPD cases detected in clinical, non-tumor cases are reported in the literature. Recently, these cases were summarized in a regularly updated, freely available online database http://www.med.uni-jena.de/fish/sSMC/00START-UPD.htm. Based of this, here the presently known imprinting syndromes, the chromosomal contribution to UPD phenomenon, and the cytogenetic subgroups of UPD, including cases with normal, abnormal balanced or unbalanced karyotype (like e.g. small supernumerary marker chromosomes and Robertsonian translocations and segmental UPD are reviewed. Furthermore, chromosome fragmentation as a possible mechanism of trisomic rescue is discussed, which might help to explain the observed 1:9 rate of maternal versus paternal UPD present in cases with original trisomic karyotypes. Overall, as UPD is more but an interesting rarity, the genetic background of each "UPD-patient" needs to be characterized besides by molecular methods, also by molecular cytogenetics in detail.

    Tumor-associated stromal cells are dynamic characters that endorse the carcinogenic process in a multitude of ways. The tumor microenvironment plays a crucial role throughout the tumor progression, which includes initiation, growth, invasion, and metastasis. The tumor microenvironment consists of cellular and non-cellular components. Tumor-associated stromal cell types include the microbiome, immune cells including macrophages, dendritic and T-cells, cells associated with blood and lymphatic vessels including pericytes and endothelial cells, fibroblasts, neuronal cells, and adipocytes. The non-cellular components of the microenvironment include matrix proteins and secreted factors. The development of therapies that target the mechanisms by which stromal cells contribute to successful tumorigenesis is major goal of upcoming cancer research. The purpose of this review is to present a comprehensive discussion of the role of each of the tumor-associated stromal cell types in the carcinogenic process with a special focus on target development and therapeutic intervention. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

    Full Text Available The well-known urban heat island (UHI effect recognizes prevailing patterns of warmer urban temperatures relative to surrounding rural landscapes. Although UHIs are often visualized as single features, internal variations within urban landscapes create distinctive microclimates. Evaluating intraurban microclimate variability presents an opportunity to assess spatial dimensions of urban environments and identify locations that heat or cool faster than other locales. Our study employs mobile weather units and fixed weather stations to collect air temperatures across Roanoke, Virginia, USA, on selected dates over a two-year interval. Using this temperature data, together with six landscape variables, we interpolated (using Kriging and Random Forest air temperatures across the city for each collection period. Our results estimated temperatures with small mean square errors (ranging from 0.03 to 0.14; landscape metrics explained between 60 and 91% of temperature variations (higher when the previous day’s average temperatures were included as a variable. For all days, similar spatial patterns appeared for cooler and warmer areas in mornings, with distinctive patterns as landscapes warmed during the day and over successive days. Our results revealed that the most potent landscape variables vary according to season and time of day. Our analysis contributes new dimensions and new levels of spatial and temporal detail to urban microclimate research.

  11. Michael Faraday and his contribution to anesthesia.

    Michael Faraday (1791-1867) was a protégé of Humphry Davy. He became one of Davy's successors as Professor of Chemistry at the Royal Institution of Great Britain. Of Faraday's many brilliant discoveries in chemistry and physics, probably the best remembered today is his work on electromagnetic induction. Faraday's contribution to introduction of anesthesia was his published announcement in 1818 that inhalation of the vapor of ether produced the same effects on mentation and consciousness as the breathing of nitrous oxide. He most likely became familiar with the central nervous system effects of nitrous oxide through his association with Davy, an avid user of the gas. Sulfuric ether was a common, convenient, cheap, and easily available substance, in contrast to nitrous oxide, which required expensive, cumbersome, and probably not widely available apparatus for its production and administration. The capability for inhaling intoxicating vapors eventually became commonly available with the use of ether instead of the gas. The first surgical anesthetics were a consequence of the resulting student "ether frolics." The 1818 announcement on breathing ether vapor was published anonymously; however, notations in Faraday's handwriting in some of his personal books clearly establish Michael Faraday as the author of this brief communication.

    The common oral diseases as well as oral cancer have the characteristic of field cancerization or field effect. Field cancerization, characterized by phenotypic and genetic changes in the neighboring cells of the frank cancer cells, is a clinical phenomenon first found in head and neck cancers. Field cancerization of the epithelia is currently a widely-accepted model in cancer biology as a manifestation of cancer progression. The concomitant changes in the tumor microenvironment have drawn more attention recently. Could the changes in the tumor microenvironment and the epithelial field cancerization concepts be linked? In view of the importance of stroma in the development of epithelium and evidence in carcinoma-associated stroma, we propose the question if stroma not only reciprocates the neoplastic changes of the epithelia, but also contributes to field cancerization. Actually one perspective paper pointed out that healing wound can influence the recurrence of field cancerization. In another words, the microenvironment of healing wound determines the prognosis of field cancerization. Based on the literatures published and our own work, we hypothesize a new model of field cancerization focusing on the co-evolution of the tumor microenvironment. We suggest that the microenvironment cannot be neglected when treating diseases with characteristics of field cancerization. Copyright 2010 Elsevier Ltd. All rights reserved.

  13. The contributions of Fridrikh Tsander: a memoir

    Soviet space pioneer Fridrikh Tsander (1887-1933) is a seminal figure in the earliest history of the theory and development of spaceflight. He saw himself as taking the theoretical groundwork laid at the turn of this century by Konstantin Tsiolkovsky, and extending it to the practical reality of taking man into space. Tsander combined the ability to generate creative concepts for accomplishing his goals, and the tenacity to perform numerous experiments, with a dedication to organizing public support, particularly among youth, for his dream to go "Forward to Mars." Those young men he inspired and trained went on to make significant contributions to the Soviet space effort. The lack of knowledge today about his work is not due to any shortcomings on his part. Tsander died in 1933, at the age of 46, just at the moment that government support for large-scale rocket experiments was being realized, and dramatic breakthroughs could be made. Lacking such support throughout his life limited what Tsander was able to practically realize, but visionary concepts he originated are still being worked on today, such as the "combining" of aircraft and rockets for spaceflight. Those who worked with Tsander, and continued after him, including S.P. Korolev, readily acknowledge Fridrikh Tsander's central place in the history of astronautics.

    Hemifacial spasm (HFS) is caused by pulsative vascular compression of the root exit zone (REZ) of the facial nerve. However, the mechanism that causes the offending vessels to compress the REZ has not been clarified. Elongation of intracranial arteries due to arteriosclerosis is one possibility, but such arteriosclerotic changes are not observed very frequently among patients with HFS. The aim of the present study was to investigate whether arteriosclerotic changes would contribute to the pathogenesis of HFS. This study included 111 HFS patients, all of whom were Japanese. The prevalence rates of hypertension, hyperlipidemia, and diabetes mellitus were examined as risk factors of atherosclerosis, and the cardio-ankle vascular index (CAVI) was measured as an indicator of arteriosclerotic change. The severity of white matter lesions (WMLs) in HFS patients was measured by magnetic resonance imaging. These data were compared with data from healthy Japanese controls. The prevalence rates of the risk factors for atherosclerosis in the HFS patients were not higher than those in the general Japanese population. The CAVI scores for the HFS patients were similar to, or lower than those in the healthy controls for all age groups except 60 to 69-year-old men. The severity of WMLs in the HFS patients was not significantly worse than that in the controls. It is suggested that arteriosclerotic changes are not involved in the pathogenesis of HFS, and that vascular compression syndromes are attributable to anatomical features of the intracranial arteries and facial nerves formed during the prenatal stage.

    Abstract: The article discusses the developments in Shona lexicography during the colonial eraand the contribution made by the missionaries in general and Father M. Hannan in particularwhich later resulted in the on-going process of compiling monolingual dictionaries by the AfricanLanguages Research Institute (ALRI (into which the ALLEX project has been transformed. Themissionaries employed various methods that did not only signal the beginning of an economicallyexploitative relationship between "the West and the rest of us" but also had ancillary cultural consequences(Dathorne 1975: 3. Their motives towards the development of African literature in generaland Zimbabwean lexicographic work in particular were primarily evangelical and not to furthercreative writing. This caused Father Hannan to experience problems not only in his translationof the Shona Bible but also in his Standard Shona Dictionary. Hannan is used as an example becausehis translation problems were typical of those experienced by all missionaries. Hannan's dictionarywas a welcome new development using the orthography introduced in 1931 and revised in 1955.The aim of his dictionary was "to record Shona words in Standard Shona spelling" (Hannan 1959:ix. Hannan's dictionary has made a considerable contribution to standardising Shona orthography.

  16. The soil physics contributions of Edgar Buckingham

    Nimmo, J.R.; Landa, E.R.

    2005-01-01

    During 1902 to 1906 as a soil physicist at the USDA Bureau of Soils (BOS), Edgar Buckingham originated the concepts of matric potential, soil-water retention curves, specific water capacity, and unsaturated hydraulic conductivity (K) as a distinct property of a soil. He applied a formula equivalent to Darcy's law (though without specific mention of Darcy's work) to unsaturated flow. He also contributed significant research on quasi-empirical formulas for K as a function of water content, water flow in capillary crevices and in thin films, and scaling. Buckingham's work on gas flow in soils produced paradigms that are consistent with our current understanding. His work on evaporation elucidated the concept of self-mulching and produced sound and sometimes paradoxical generalizations concerning conditions that favor or retard evaporation. Largely overshadowing those achievements, however, is that he launched a theory, still accepted today, that could predict transient water content as a function of time and space. Recently discovered documents reveal some of the arguments Buckingham had with BOS officials, including the text of a two-paragraph conclusion of his famous 1907 report on soil water, and the official letter documenting rejection of that text. Strained interpersonal relations motivated the departure of Buckingham and other brilliant physicists (N.E. Dorsey, F.H. King, and Lyman Briggs) from the BOS during 1903 to 1906. Given that Buckingham and his BOS colleagues had been rapidly developing the means of quantifying unsaturated flow, these strained relations probably slowed the advancement of unsaturated flow theory. ??

    Aggressive periodontitis is characterized by a rapid and severe periodontal destruction in young systemically healthy subjects. A greater prevalence is reported in Africans and African descendent groups than in Caucasians and Hispanics. We first fine mapped the interval 1q24.2 to 1q31.3 suggested as containing an aggressive periodontitis locus. Three hundred and eighty-nine subjects from 55 pedigrees were studied. Saliva samples were collected from all subjects, and DNA was extracted. Twenty-one single nucleotide polymorphisms were selected and analyzed by standard polymerase chain reaction using TaqMan chemistry. Non-parametric linkage and transmission distortion analyses were performed. Although linkage results were negative, statistically significant association between two markers, rs1935881 and rs1342913, in the FAM5C gene and aggressive periodontitis (p = 0.03) was found. Haplotype analysis showed an association between aggressive periodontitis and the haplotype A-G (rs1935881-rs1342913; p = 0.009). Sequence analysis of FAM5C coding regions did not disclose any mutations, but two variants in conserved intronic regions of FAM5C, rs57694932 and rs10494634, were found. However, these two variants are not associated with aggressive periodontitis. Secondly, we investigated the pattern of FAM5C expression in aggressive periodontitis lesions and its possible correlations with inflammatory/immunological factors and pathogens commonly associated with periodontal diseases. FAM5C mRNA expression was significantly higher in diseased versus healthy sites, and was found to be correlated to the IL-1β, IL-17A, IL-4 and RANKL mRNA levels. No correlations were found between FAM5C levels and the presence and load of red complex periodontopathogens or Aggregatibacter actinomycetemcomitans. This study provides evidence that FAM5C contributes to aggressive periodontitis. PMID:20383335

  18. Porting Social Media Contributions with SIOC

    Bojars, Uldis; Breslin, John G.; Decker, Stefan

    Social media sites, including social networking sites, have captured the attention of millions of users as well as billions of dollars in investment and acquisition. To better enable a user's access to multiple sites, portability between social media sites is required in terms of both (1) the personal profiles and friend networks and (2) a user's content objects expressed on each site. This requires representation mechanisms to interconnect both people and objects on the Web in an interoperable, extensible way. The Semantic Web provides the required representation mechanisms for portability between social media sites: it links people and objects to record and represent the heterogeneous ties that bind each to the other. The FOAF (Friend-of-a-Friend) initiative provides a solution to the first requirement, and this paper discusses how the SIOC (Semantically-Interlinked Online Communities) project can address the latter. By using agreed-upon Semantic Web formats like FOAF and SIOC to describe people, content objects, and the connections that bind them together, social media sites can interoperate and provide portable data by appealing to some common semantics. In this paper, we will discuss the application of Semantic Web technology to enhance current social media sites with semantics and to address issues with portability between social media sites. It has been shown that social media sites can serve as rich data sources for SIOC-based applications such as the SIOC Browser, but in the other direction, we will now show how SIOC data can be used to represent and port the diverse social media contributions (SMCs) made by users on heterogeneous sites.

  20. The Middle Ages Contributions to Cardiovascular Medicine

    Directory of Open Access Journals (Sweden)

    André Silva Ranhel

    Full Text Available Abstract The historical period called the Middle Ages, a long interval between the 5th and the 15th centuries, is still commonly known as the Dark Ages, especially in the area of health sciences. In the last decades, this "classic" view of the Middle Ages has been gradually modified with advances in historiographical studies and the history of science. During that period in Western Europe, knowledge about the human body suffered a regression in terms of anatomy and physiology, with the predominance of religious conceptions mainly about diseases and their treatments. Knowledge on the cardiovascular system and heart diseases has been classically described as a repetition of the concepts developed by Galen from the dissection of animals and his keen sense of observation. However, the Middle East, especially Persia, was the birth place of a lot of intellectuals who preserved the ancient knowledge of the Greeks while building new knowledge and practices, especially from the 8th to the 13th century. The invasion of the Arabs in North of Africa and the Iberian Peninsula and the eclosion of the Crusades resulted in a greater contact between the East and the West, which in turn brought on the arrival of the Arab medical knowledge, among others, to 12th century Europe. Such fact contributed to an extremely important change in the scientific medical knowledge in the West, leading to the incorporation of different concepts and practices in the field of cardiovascular Medicine. The new way of teaching and practicing Medicine of the great Arab doctors, together with the teaching hospitals and foundations in the Koran, transformed the Medicine practiced in Europe definitely. The objective of this paper is to describe the knowledge drawn up from the Middle Ages about the cardiovascular system, its understanding and therapeutic approach to cardiologists and cardiovascular surgeons.

Exploration of putative genetic causal factors such as variants in the CNTNAP2 gene showed a varying pattern of associations with these traits. An alternative predictive model of ASD was derived using four individual measures: the coherence subscale of the Children's Communication Checklist (9y, the Social and Communication Disorders Checklist (91 m, repetitive behaviour (69 m and the sociability subscale of the Emotionality Activity and Sociability measure (38 m. Although univarably these traits performed better than some factors, their combined explanations of ASD were similar (R(2 =  0.48.

  2. Contribution of Warsaw Logicians to Computational Logic

    2016-06-01

    Full Text Available The newly emerging branch of research of Computer Science received encouragement from the successors of the Warsaw mathematical school: Kuratowski, Mazur, Mostowski, Grzegorczyk, and Rasiowa. Rasiowa realized very early that the spectrum of computer programs should be incorporated into the realm of mathematical logic in order to make a rigorous treatment of program correctness. This gave rise to the concept of algorithmic logic developed since the 1970s by Rasiowa, Salwicki, Mirkowska, and their followers. Together with Pratt’s dynamic logic, algorithmic logic evolved into a mainstream branch of research: logic of programs. In the late 1980s, Warsaw logicians Tiuryn and Urzyczyn categorized various logics of programs, depending on the class of programs involved. Quite unexpectedly, they discovered that some persistent open questions about the expressive power of logics are equivalent to famous open problems in complexity theory. This, along with parallel discoveries by Harel, Immerman and Vardi, contributed to the creation of an important area of theoretical computer science: descriptive complexity. By that time, the modal μ-calculus was recognized as a sort of a universal logic of programs. The mid 1990s saw a landmark result by Walukiewicz, who showed completeness of a natural axiomatization for the μ-calculus proposed by Kozen. The difficult proof of this result, based on automata theory, opened a path to further investigations. Later, Bojanczyk opened a new chapter by introducing an unboundedness quantifier, which allowed for expressing some quantitative properties of programs. Yet another topic, linking the past with the future, is the subject of automata founded in the Fraenkel-Mostowski set theory. The studies on intuitionism found their continuation in the studies of Curry-Howard isomorphism. ukasiewicz’s landmark idea of many-valued logic found its continuation in various approaches to incompleteness and uncertainty.

    Systematic reviews comprehensively summarize evidence about the effectiveness of conservation interventions. We investigated the contribution to management decisions made by this growing body of literature. We identified 43 systematic reviews of conservation evidence, 23 of which drew some concrete conclusions relevant to management. Most reviews addressed conservation interventions relevant to policy decisions; only 35% considered practical on-the-ground management interventions. The majority of reviews covered only a small fraction of the geographic and taxonomic breadth they aimed to address (median = 13% of relevant countries and 16% of relevant taxa). The likelihood that reviews contained at least some implications for management tended to increase as geographic coverage increased and to decline as taxonomic breadth increased. These results suggest the breadth of a systematic review requires careful consideration. Reviews identified a mean of 312 relevant primary studies but excluded 88% of these because of deficiencies in design or a failure to meet other inclusion criteria. Reviews summarized on average 284 data sets and 112 years of research activity, yet the likelihood that their results had at least some implications for management did not increase as the amount of primary research summarized increased. In some cases, conclusions were elusive despite the inclusion of hundreds of data sets and years of cumulative research activity. Systematic reviews are an important part of the conservation decision making tool kit, although we believe the benefits of systematic reviews could be significantly enhanced by increasing the number of reviews focused on questions of direct relevance to on-the-ground managers; defining a more focused geographic and taxonomic breadth that better reflects available data; including a broader range of evidence types; and appraising the cost-effectiveness of interventions. © 2013 The Authors.

  4. Serotonergic contribution to boys' behavioral regulation.

    Full Text Available Animal and human adult studies reveal a contribution of serotonin to behavior regulation. Whether these findings apply to children is unclear. The present study investigated serotonergic functioning in boys with a history of behavior regulation difficulties through a double-blind, acute tryptophan supplementation procedure.Participants were 23 boys (age 10 years with a history of elevated physical aggression, recruited from a community sample. Eleven were given a chocolate milkshake supplemented with 500 mg tryptophan, and 12 received a chocolate milkshake without tryptophan. Boys engaged in a competitive reaction time game against a fictitious opponent, which assessed response to provocation, impulsivity, perspective taking, and sharing. Impulsivity was further assessed through a Go/No-Go paradigm. A computerized emotion recognition task and a staged instrumental help incident were also administered.Boys, regardless of group, responded similarly to high provocation by the fictitious opponent. However, boys in the tryptophan group adjusted their level of responding optimally as a function of the level of provocation, whereas boys in the control group significantly decreased their level of responding towards the end of the competition. Boys in the tryptophan group tended to show greater perspective taking, tended to better distinguish facial expressions of fear and happiness, and tended to provide greater instrumental help to the experimenter.The present study provides initial evidence for the feasibility of acute tryptophan supplementation in children and some effect of tryptophan supplementation on children's behaviors. Further studies are warranted to explore the potential impact of increased serotonergic functioning on boys' dominant and affiliative behaviors.

  5. Elements that contribute to healthy building design.

    The elements that contribute to a healthy building are multifactorial and can be discussed from different perspectives. WE PRESENT THREE VIEWPOINTS OF DESIGNING A HEALTHY BUILDING: the importance of sustainable development, the role of occupants for ensuring indoor air quality, and ongoing developments related to indoor finishes with low chemical emissions and good fungal resistance. Sustainable design rediscovers the social, environmental, and technical values of pedestrian and mixed-use communities, using existing infrastructures including "main streets" and small-town planning principles and recapturing indoor-outdoor relationships. This type of design introduces nonpolluting materials and assemblies with lower energy requirements and higher durability and recyclability. Building occupants play a major role in maintaining healthy indoor environments, especially in residences. Contributors to indoor air quality include cleaning habits and other behaviors; consumer products, furnishings, and appliances purchases, as well as where and how the occupants use them. Certification of consumer products and building materials as low-emitting products is a primary control measure for achieving good indoor air quality. Key products in this respect are office furniture, flooring, paints and coatings, adhesives and sealants, wall coverings, wood products, textiles, insulation, and cleaning products. Finishing materials play a major role in the quality of indoor air as related to moisture retention and mold growth. Sustainable design emphasizes the needs of infrastructure, lower energy consumption, durability, and recyclability. To ensure good indoor air quality, the product development for household use should aim to reduce material susceptibility to contaminants such as mold and should adopt consumer-oriented product labeling.

    A wound is damage of a tissue usually caused by laceration of a membrane, generally the skin. Wound healing is accomplished in three stages in healthy individuals, including inflammatory, proliferative, and remodeling stages. Healing of wounds normally starts from the inflammatory phase and ends up in the remodeling phase, but chronic wounds remain in an inflammatory stage and do not show progression due to some specific reasons. Chronic wounds are classified in different categories, such as diabetic foot ulcer (DFU), venous leg ulcers (VLU) and pressure ulcer (PU), surgical site infection (SSI), abscess, or trauma ulcers. Globally, the incidence rate of DFU is 1-4 % and prevalence rate is 5.3-10.5 %. However, colonization of pathogenic bacteria at the wound site is associated with wound chronicity. Most chronic wounds contain more than one bacterial species and produce a synergetic effect that results in previously non-virulent bacterial species becoming virulent and causing damage to the host. While investigating bacterial diversity in chronic wounds, Staphylococcus, Pseudomonas, Peptoniphilus, Enterobacter, Stenotrophomonas, Finegoldia, and Serratia were found most frequently in chronic wounds. Recently, it has been observed that bacteria in chronic wounds develop biofilms that contribute to a delay in healing. In a mature biofilm, bacteria grow slowly due to deficiency of nutrients that results in the resistance of bacteria to antibiotics. The present review reflects the reasons why acute wounds become chronic. Interesting findings include the bacterial load, which forms biofilms and shows high-level resistance toward antibiotics, which is a threat to human health in general and particularly to some patients who have acute wounds.

  9. Contribution from pressure-sensitive adhesives

    1996-03-01

    The successful use of many security papers, foils and films depends on the technology of chemical fastening systems -- especially pressure sensitive adhesives. These are adhesives activated not by heat or by the evaporation of water or some other solvent, but simply by the act of application -- by pressure. These adhesives provide the means whereby laminations, substrates and seals are made effective. In addition to their physical properties these adhesives are often required to possess optical properties to allow the security materials to be visibly active and indeed the adhesive system may itself contribute as a carrier for a variety of security materials. Recent advances in adhesives chemistry have made it possible to achieve virtually all the required physical performance characteristics combined with a choice of optical properties ranging from total opacity to invisibility and including controlled translucency and tinting. The implications for security printing and packaging are important. Opacity is easy to achieve, for example by loading the adhesive with aluminum powder, by the selection of totally opaque materials like metallized film or by various printing processes. But achieving transparency is a different matter, and transparency is mandatory for applications involving the protection of documents, photographs, etc. with a clear film over-laminate. Obvious examples would be for passports, visas and other personal identification. But some security devices may themselves require protection; for example holograms or embossings. And transparency in the test laboratory is not enough. The Australian driving licence is stuck to the windshield, so the transparency of the adhesive must be sustained over long periods without deterioration due to prolonged u/v exposure, climatic conditions or aging. The commercial label market has helped to push the technology forward. There is a strong demand for the 'no-label look' for packaging of clear plastic and glass

    Acallosal and callosotomized subjects usually show impairments on tasks requiring bilateral interdependent motor control. However, few studies have assessed the ability of these subjects to learn a skill that requires the simultaneous contribution of each hemisphere in its acquisition. The present study examined whether acallosal and callosotomized subjects could learn a visuomotor skill that involved a motor control from either both or a single hemisphere. Eleven adult patients, six acallosal and five callosotomized, participated in this study. Seven of these patients had epileptic foci located in the frontal and/or temporal areas and one of the acallosal patients showed bilateral prefrontal atrophy following surgical removal of an orbitofrontal cyst. The performance of the experimental subjects was compared with that of 11 matched control subjects, on a modified version of a serial reaction time task developed by Nissen and Bullemer (Cogn Psychol 1987; 19: 1-32). This skill acquisition task involved bimanual or unimanual key-pressing responses to a sequence of 10 visual stimuli that was repeated 160 times. A declarative memory task was then performed to assess explicit knowledge of the sequence. None of the experimental subjects learned the task in the bimanual condition. Patients with frontal epileptic foci or orbitofrontal damage also failed to learn the task in the unimanual condition when they were using the hand contralateral to the damaged hemisphere. All other subjects, including the acallosal and callosotomized patients with temporal foci, learned the visuomotor skill as well as their controls in the unimanual condition. In spite of the absence of transfer and interhemispheric integration of procedural learning, some of the acallosal and callosotomized patients were able to learn the sequence explicitly. These findings indicate that the corpus callosum and the frontal cortical areas are important for procedural learning of a visuomotor skill. They also

    western Antarctica. For 2002 to present, the rate of ice mass loss has been 200 to 300 GT/yr in Greenland and 70 to 210 GT/yr in Antarctica, and some scientists are suggesting that the rates are accelerating. Similarly, GRACE has been used to monitor mass changes in alpine glaciers. Tamisiea et al. first characterized glacier melt along the southern coast of Alaska, more recently estimated to be occurring at a rate of 84 GT/yr. Chen et al. estimated that Patagonian glaciers are melting at a rate of 28 GT/yr, and estimated that the high mountains of central Asia lose ice at a rate of 47 GT/yr. Tapley et al. and Wahr et al. presented the first GRACE based estimates of changes in column-integrated terrestrial water storage (TWS; the sum of ground-water, soil moisture, surface waters, snow, ice, and water stored in vegetation) at continental scales. Since then, dozens of studies have shown that GRACE based estimates of regional to continental scale TWS variations agree with independent information, and some innovative uses of GRACE data have been developed. Rodell et al. (2004) and Swenson and Wahr (2006) demonstrated that by combining GRACE derived terrestrial water storage changes with observations of precipitation and runoff in a river basin scale water budget, it was possible to produce new estimates of evapotranspiration and atmospheric moisture convergence, essential climate variables that are difficult to estimate accurately. Similarly, GRACE has been used to constrain estimates of global river discharge and the contribution of changes in TWS to sea level rise. Crowley et al. observed a negative correlation between interannual TWS anomalies in the Amazon and the Congo River basin. Yeh et al. and Rodell et al. estimated regionally averaged groundwater storage variations based on GRACE and auxiliary observations. Rodell et al. and Tiwari et al. applied that method to quantify massive groundwater depletion in northern India caused by over reliance on aquifers for irration

    The contributions of neutrons to hadronic signals from the DREAM calorimeter are measured by analyzing the time structure of these signals. The neutrons, which mainly originate from the evaporation stage of nuclear breakup in the hadronic shower development process, contribute through elastic scattering off protons in the plastic scintillating fibers which provide the $dE/dx$ information in this calorimeter. This contribution is characterized by an exponential tail in the pulse shape, with a time constant of $\\sim 25$ ns. The relative contribution of neutrons to the signals increases with the distance from the shower axis. As expected, the neutrons do not contribute to the DREAM \\v{C}erenkov signals.

    Contributions from men to radiation science are well known, particularly the early contributions from such luminaries as William Roentgen, James Chadwick, Niels Bohr, Robert Oppenheimer, and the like. Although not ignored per se, beyond Marie Curie and Lise Meitner, the contributions of female nuclear scientists are not as widely recognized. This paper provides a concise historical summary of contributions to radiation science from the discovery of radiation through the current status of international leadership within the radiation protection community. Beyond lead scientists and academics, this paper also considers support personnel as well as the role women have played in the advancement of radiation epidemiology.

  10. Influence Of The Social Contributions On The Enterprise Behaviour

    Directory of Open Access Journals (Sweden)

    Nicoleta MIHĂILĂ

    2012-06-01

    Full Text Available The current fiscal system comprises a multitude of taxes, dues and contributions which the enterprise has to pay. The large number of taxes and dues to be paid put a high fiscal pressure on the enterprise and the social contributions are a determining factor in the manifestation of the fiscal behaviour of the enterprises. The employer has to pay to the state a significant proportion of the gross wage of the employee, almost 30%, which includes: the contribution to the social insurances, the contribution to the unemployment fund, the contribution to the Single National Fund for Health Social Insurance, the contribution to the guarantee fund for wages, the contribution to the health insurances, the contribution to the fund for accidents and the fee for the Chamber of Labour. The employee must also pay the state a total of 32.5% which consists of the contribution to the social insurances, the contribution to the unemployment fund, the contribution to the health insurances and the income tax. A simple calculation shows that the net income of the employee from his/her gross income is much lower than the revenue to the state from this wage. The state charges a burdening 45% on each job, while the employee earns almost 55%. This percentage is an obstacle for business development in Romania, where the labour force is overtaxed. Within this context, the pressure presumed by any increase of the minimal national wage is very strong for the employers and it generates unemployment, informal work and tax evasion.

  12. Consistent estimation of Gibbs energy using component contributions.

    Directory of Open Access Journals (Sweden)

    Elad Noor

    Full Text Available Standard Gibbs energies of reactions are increasingly being used in metabolic modeling for applying thermodynamic constraints on reaction rates, metabolite concentrations and kinetic parameters. The increasing scope and diversity of metabolic models has led scientists to look for genome-scale solutions that can estimate the standard Gibbs energy of all the reactions in metabolism. Group contribution methods greatly increase coverage, albeit at the price of decreased precision. We present here a way to combine the estimations of group contribution with the more accurate reactant contributions by decomposing each reaction into two parts and applying one of the methods on each of them. This method gives priority to the reactant contributions over group contributions while guaranteeing that all estimations will be consistent, i.e. will not violate the first law of thermodynamics. We show that there is a significant increase in the accuracy of our estimations compared to standard group contribution. Specifically, our cross-validation results show an 80% reduction in the median absolute residual for reactions that can be derived by reactant contributions only. We provide the full framework and source code for deriving estimates of standard reaction Gibbs energy, as well as confidence intervals, and believe this will facilitate the wide use of thermodynamic data for a better understanding of metabolism.

  13. Does Tenure Matter? Factors Influencing Faculty Contributions to Institutional Repositories

    Directory of Open Access Journals (Sweden)

    Anne M. Casey

    2012-05-01

    Full Text Available INTRODUCTION Institutional repositories (IRs provide colleges and universities a way to ensure stability of access to and dissemination of digital scholarly communications. Yet, many institutions report that faculty willingness to contribute to IRs is often limited. This study investigates faculty attitudes about IR contributions by tenure status and category of material. METHODS Two focus group interviews were conducted in the spring of 2009 among English department faculty at a large Midwestern university. One group consisted of tenured faculty and the other of tenure-track and adjunct faculty. RESULTS Both groups recognize the benefit of open access to research materials but expressed concern about their intellectual property rights. Untenured faculty spoke more about nonprint research. Both groups also shared concerns about contributing instructional materials, primarily in regard to plagiarism and outdated materials. In regard to faculty service, the tenured group discussed many items they would contribute, while the untenured faculty mentioned very little. DISCUSSION Some minor differences emerged related to experience and tenure status in regard to contributing research and instructional artifacts, but the major variation was the strong support tenured participants gave for contributing service items, compared to the untenured faculty, who did not view this category positively. Tenured faculty viewed the IR as a way to document their own service activities, investigate those of colleagues, and had fewer concerns about plagiarism or other negative effects in the service category. CONCLUSION Promoting faculty contribution of service-related items to an IR may be a way to encourage larger numbers to participate.

    2017-01-01

    To evaluate the contribution of Turkish scientists to four journals published by Journal of Neurosurgery (JNS) Publishing Group and to Acta Neurochirurgica (AN) and to its Supplement (ANS). We reviewed every issue of those journals to December 2015 for the total number of articles, articles produced from studies performed entirely in Turkey, and for publications overseas co-authored by the Turkish scientists using the websites of these journals. Citations were searched using "Web of Science" and "Google Scholar" databases. The total number of articles published was 19822 for JNS, 3227 for JNS Spine, 2526 for JNS Pediatrics and 2997 for Neurosurgical Focus. Turkish contribution was 556 articles. 337 (60.61%) articles were the products of studies performed entirely in Turkey, while 219 (39.38%) articles came from overseas, co-authored by Turkish scientists. Overall contribution was 1.94%. A total of 6469 articles were published in AN. 340 papers were the products of studies performed entirely in Turkey. Turkish scientists working overseas co-authored 37 articles. Total contribution was 377 articles (5.82%). 4134 papers had been published in ANS. Contribution was 69 articles (1.66%). Turkish contribution to these journals has started late. The gap has been compensated with publications in the last two decades. Manuscripts of higher scientific level with greater number of citations are needed to increase Turkish contribution to such journals.

    Sesma, Heather Whitney; Mahone, E Mark; Levine, Terry; Eason, Sarah H; Cutting, Laurie E

    2009-05-01

    Although word recognition deficits (WRD) are a known cause of reading comprehension deficits (RCD), other contributions to RCD, including executive function (EF), have not been fully explored. We examined the contribution of EF (working memory and planning), along with attention, decoding, fluency, and vocabulary to reading comprehension in 60 children (including 16 WRD and 10 RCD), ages 9-15 years. After controlling for commonly accepted contributors to reading comprehension (i.e., attention, decoding skills, fluency, and vocabulary), EF continued to make a significant contribution to reading comprehension but not to word recognition skills. These findings highlight the need for consideration of the role of EF in RCD.

Such thoughts aim to discuss how this teaching enters school education in the context of neoliberalism. Assuming that the emptiness in Geography teaching in school education is a result of Brazilian educational policies in neoliberalism, we intend to characterize the impairment of the critical perspective on this area of knowledge and present some contributions of historical critical pedagogy to face and overcome the current order. Besides, we seek to highlight the required knowledge to achieve an education that contributes to build a different society.

  2. The contribution of Giordano Bruno to the principle of relativity

    Science.gov (United States)

    De Angelis, Alessandro; Santo, Catarina Espirito

    2015-11-01

    The trial and condemnation of Giordano Bruno was mainly based on arguments of a philosophical and theological nature, and therefore different from Galileo Galilei's trial. Such elements contribute to unfairly devalue the scientific contribution of Bruno and do not properly account for his contribution to physics. This paper discusses the contribution that Bruno made to the principle of relativity. This was first discussed by Galileo Galilei in 1632 using the metaphor known today as 'Galileo's ship', but we shall show that this same metaphor and some of the examples in Galileo's book were already contained in a dialogue published by Bruno in 1584. In fact, Bruno largely anticipated the arguments of Galilei on the relativity principle, in particular to support the Copernican view. It is likely that Galilei was aware of Bruno's work, and it is possible that the young Galilei discussed it with Bruno, since they both stayed in Venice for long periods in 1592.

    2010-07-01

    This research explores the relationship between political campaign contributions, lobbying and post-Hurricane Katrina cleanup and reconstruction contracts. Specifically, a case-control study design is used to determine whether campaign contributions to national candidates in the 2000-04 election cycles and/or the employment of lobbyists and lobbying firms increased a company's probability of receiving a post-hurricane contract. Results indicate that both a campaign contribution dichotomous variable and the dollar amount of contributions are significantly related to whether a company received a contract, but that lobbying activity was not. These findings are discussed in the context of previous research on the politics of natural disasters, government contracting and governmental and corporate deviance.

    2017-05-01

    Graphene, the most studied and explored 2D structure has unusual thermal properties such as negative thermal expansion, high thermal conductivity etc. We have already studied the thermal expansion behavior and various thermodynamic properties of pure graphene like heat capacity, entropy and free energy. The results of thermal expansion and various thermodynamic properties match well with available theoretical studies. For a deeper understanding of these properties, we analyzed the contribution of each phonon branch towards the total value of the individual property. To compute these properties, the dynamical matrix was calculated using VASP code where the density functional perturbation theory (DFPT) is employed under quasi-harmonic approximation in interface with phonopy code. It is noticed that transverse mode has major contribution to negative thermal expansion and all branches have almost same contribution towards the various thermodynamic properties with the contribution of ZA mode being the highest.

This problem can be connected to the weakness of the administration and the inefficacy of the competent bodies, to high rates of contributions and a general lack of trust in the public pension system based on intergenerational solidarity. One of the most important determinants of evasion is the benefit deriving from the insurance, that is, the relation between the contributions and the pension. Insured persons who have worked their whole lives and have reached old-age pensions have an unfavourable ratio of contributions paid in and amount of pension received, because funds for pensions have been redistributed to several other categories. After a brief explanation of the pension reform, we draw attention to certain legislative inconsistencies connected with retirement insurance. The paper closes with a proposal for possible measures for the improvement of collection.

  19. Bioethicists Can and Should Contribute to Addressing Racism.

    Danis, Marion; Wilson, Yolonda; White, Amina

    2016-01-01

    The problems of racism and racially motivated violence in predominantly African American communities in the United States are complex, multifactorial, and historically rooted. While these problems are also deeply morally troubling, bioethicists have not contributed substantially to addressing them. Concern for justice has been one of the core commitments of bioethics. For this and other reasons, bioethicists should contribute to addressing these problems. We consider how bioethicists can offer meaningful contributions to the public discourse, research, teaching, training, policy development, and academic scholarship in response to the alarming and persistent patterns of racism and implicit biases associated with it. To make any useful contribution, bioethicists will require preparation and should expect to play a significant role through collaborative action with others.

  6. HFCs contribution to the greenhouse effect. Present and projected estimations

    Energy Technology Data Exchange (ETDEWEB)

    1997-12-31

    This paper reviews data that can be used to calculate hydrofluorocarbon (HFC) contribution to the greenhouse effect and compare it to other trace gas contributions. Projections are made for 2010 and 2100 on the basis of available emission scenarios. Industrial judgement on the likelihood of those scenarios is also developed. Calculations can be made in two different ways: from Global Warming Potential weighted emissions of species or by direct calculation of radiative forcing based on measured and projected atmospheric concentrations of compounds. Results show that HFCs corresponding to commercial uses have a negligible contribution to the greenhouse effect in comparison with other trace gases. The projected contributions are also very small even if very high emission scenarios are maintained for decades. In 2010 this contribution remains below 1%. Longer term emissions projections are difficult. However, based on the IPCC scenario IS92a, in spite of huge emissions projected for the year 2100, the HFC contribution remains below 3%. Actually many factors indicate that the real UFC contribution to the greenhouse effect will be even smaller than presented here. Low emissive systems and small charges will likely improve sharply in the future and have drastically improved in the recent past. HFC technology implementation is likely to grow in the future, reach a maximum before the middle of the next century; the market will stabilise driven by recycling, closing of systems and competitive technologies. This hypothesis is supported by previous analysis of the demand for HTCs type applications which can be represented by {open_quotes}S{close_quotes} type curves and by recent analysis indicating that the level of substitution of old products by HFCs is growing slowly. On the basis of those data and best industrial judgement, the contribution of HFCs to the greenhouse effect is highly likely to remain below 1% during the next century. 11 refs., 2 figs., 5 tabs.

  7. Employer contribution and premium growth in health insurance.

    Liu, Yiyan; Jin, Ginger Zhe

    2015-01-01

    We study whether employer premium contribution schemes could impact the pricing behavior of health plans and contribute to rising premiums. Using 1991-2011 data before and after a 1999 premium subsidy policy change in the Federal Employees Health Benefits Program (FEHBP), we find that the employer premium contribution scheme has a differential impact on health plan pricing based on two market incentives: 1) consumers are less price sensitive when they only need to pay part of the premium increase, and 2) each health plan has an incentive to increase the employer's premium contribution to that plan. Both incentives are found to contribute to premium growth. Counterfactual simulation shows that average premium would have been 10% less than observed and the federal government would have saved 15% per year on its premium contribution had the subsidy policy change not occurred in the FEHBP. We discuss the potential of similar incentives in other government-subsidized insurance systems such as the Medicare Part D and the Health Insurance Marketplace under the Affordable Care Act.

    Benton, David; Shaffer, Franklin

    2016-11-01

    As of 1 January 2016, the UN sustainable development goals (SDGs) became the focus of global efforts on a wide range of development agenda. The SDGs have subsumed the work of the UN millennium development goals (MDGs), so it is timely to reflect on the contribution made by nurses and midwives, so that we can optimise the profession's contribution to the 17 SDGs. This article reports the results of a scientometrics analysis of the published literature related to the MDGs and SDGs indexed in CINAHL, which identified the underlying themes addressed by nurses and midwives. It shows how analysis demonstrates that although nursing was slow to engage with the MDG agenda, it has made some progress in contributing to SDG scholarship. So far this contribution has been narrowly focused, but the profession could contribute to all 17 of the SDG goals. Routine updates of the analysis described here could help monitor progress, identify gaps in nursing's contributions to the goals, and provide further impetus to its engagement in this major global policy initiative.

  10. Contribution Index Based on Green Building Certification Systems

    Full Text Available Green Building Certification Systems (GBCS are carried out in many countries due to the rising awareness of the importance of sustainability in the building industry. The intention should have motivated participants to construct and operate buildings sustainably, however, there is not yet a method developed to investigate the motivation of the participants. Based on the GBCS, this paper proposes the contribution index as a standard global method to analyze the performance of participants in the green building industry. Three contribution indices, namely Frequency Contribution Index (FCI, Intensity Contribution Index (ICI and Comprehensive Contribution Index (CCI that concern each different category of participant, have been formulated. Three further analyses based on the index were undertaken to investigate some features of the industry. A case study of Singapore was conducted to show how the contribution index could be used to extract industry patterns and trends and assess the participants’ performance in the green building industry. Interviews with experts provide some suggested applications and support for the findings.

  11. Water-leaving contribution to polarized radiation field over ocean.

    The top-of-atmosphere (TOA) radiation field from a coupled atmosphere-ocean system (CAOS) includes contributions from the atmosphere, surface, and water body. Atmospheric correction of ocean color imagery is to retrieve water-leaving radiance from the TOA measurement, from which ocean bio-optical properties can be obtained. Knowledge of the absolute and relative magnitudes of water-leaving signal in the TOA radiation field is important for designing new atmospheric correction algorithms and developing retrieval algorithms for new ocean biogeochemical parameters. In this paper we present a systematic sensitivity study of water-leaving contribution to the TOA radiation field, from 340 nm to 865 nm, with polarization included. Ocean water inherent optical properties are derived from bio-optical models for two kinds of waters, one dominated by phytoplankton (PDW) and the other by non-algae particles (NDW). In addition to elastic scattering, Raman scattering and fluorescence from dissolved organic matter in ocean waters are included. Our sensitivity study shows that the polarized reflectance is minimized for both CAOS and ocean signals in the backscattering half plane, which leads to numerical instability when calculating water leaving relative contribution, the ratio between polarized water leaving and CAOS signals. If the backscattering plane is excluded, the water-leaving polarized signal contributes less than 9% to the TOA polarized reflectance for PDW in the whole spectra. For NDW, the polarized water leaving contribution can be as much as 20% in the wavelength range from 470 to 670 nm. For wavelengths shorter than 452 nm or longer than 865 nm, the water leaving contribution to the TOA polarized reflectance is in general smaller than 5% for NDW. For the TOA total reflectance, the water-leaving contribution has maximum values ranging from 7% to 16% at variable wavelengths from 400 nm to 550 nm from PDW. The water leaving contribution to the TOA total reflectance can

    To identify the most common serious adverse events that occurred in nursing homes and their most frequent contributing factors to the improvement of safe nursing care. There is a need to improve safe nursing care in nursing homes. Residents are often frail and vulnerable with extensive needs for nursing care. A relatively minor adverse event in nursing care can cause serious injury that could have been preventable. This was a retrospective study, with a total sample of data regarding adverse events (n = 173) in nursing homes, concerning nursing care reported by healthcare providers in Sweden to the Health and Social Care Inspectorate. The reports were analysed with content analysis, and the frequencies of the adverse events, and their contributing factors, were described with descriptive statistics. Medication errors, falls, delayed or inappropriate intervention and missed nursing care contributed to the vast majority (89%) of the serious adverse events. A total of 693 possible contributing factors were identified. The most common contributing factors were (i) lack of competence, (ii) incomplete or lack of documentation, (iii) teamwork failure and (iv) inadequate communication. The contributing factors frequently interacted yet they varied between different groups of serious adverse events. The resident's safety depends on the availability of staff's competence as well as adequate documentation about the resident's condition. Lack of competence was underestimated by healthcare providers. Registered nurses and assistant nurses need to have awareness of contributing factors to adverse events in nursing care. A holistic approach to improve patient safety in nursing homes requires competence of the staff, safe environments as well as resident's and relative's participation. © 2017 John Wiley & Sons Ltd.

    The purpose of this study was to determine the contributions of selected fundamental factors, such as arm length, sitting height, simple vision reaction time (SVRT), choice vision reaction time (CVRT), muscle strength, and range of motion (ROM) at the shoulder, elbow, and wrist joints to wheelchair basketball (WCB) performance as measured by season statistics and coaches' evaluation. Thirty-seven Paralympic WCB players from seven countries participated in this study. A computerized reaction time system was used to test the SVRT and CVRT. The ROM and muscle strengths of the shoulder, elbow, and wrist joints were measured using a goniometer and MP DA100B BioPac force measurement system, respectively. Stepwise regression analysis was used to identify the contributions of these fundamental factors and "dimensional variables" (DV) derived from the selected factors fundamental to WCB performance. A DV represented a dimension or category of the factor, for example, the wrist flexion/extension DV represented the ROM of the wrist in flexion and extension, and the WCB performance DV represented average points, rebounds, assists, blocks, and steals per game. The results of this study demonstrated that elbow extension and wrist extension had significant contributions to average points. Sitting height, shoulder internal rotation, and elbow flexion had significant contributions to the average rebounds. Arm length had a significant contribution to average assists, and SVRT had a significant contribution to the average blocks. Wrist flexion/extension ROM DV and wrist flexion/extension strength DV had significant contributions to the WCB performance DV. Shoulder internal rotation, elbow extension, and wrist flexion/extension ROM, CVRT, and wrist flexion/extension muscle strength are important to WCB performance and should be addressed in WCB training.

  14. Foreign and Domestic Contributions to Springtime Ozone Pollution over China

    Ozone is a critical air pollutant that damages human health and vegetation. Previous studies for the United States and Europe have shown large influences of foreign emissions on domestic ozone levels, whereas the relative contributions of foreign versus domestic emissions are much less clear for China' ozone pollution. Here, we use the global chemical transport model (GEOS-Chem) simulations to quantify the springtime contributions of ozone transported to China from regions with large anthropogenic emissions. Model simulations have been validated by comparisons with ground-based measurements, aircraft, ozonesonde, and satellite observations, leading confidence to model's ability of simulating ozone over China. Our results indicate considerable influences of foreign anthropogenic pollution on China's ozone air quality. Of all ozone over China produced by global anthropogenic emissions, foreign emissions contribute 40% near the surface and increases with altitude, and the contribution reaches up to 70% in the upper troposphere. Ozone pollution from North America and Europe mainly accompany strong westerly winds and frequent cyclonic activities that are favorable to the long-range transport. European anthropogenic pollution enhanced surface ozone concentrations by 1 4 ppb over Western and Northern China. Despite much longer transport distance, the contribution from North America is greater than European contribution due to the nearly tripled anthropogenic VOC emissions. Ozone transported from South and Southeast Asia has a significant impact on Southern China, and contributes more efficiently in the upper troposphere due to strong upwelling. Anthropogenic emissions of Japan and South Korea enhance ozone over China's east coastal regions by 2 4 ppb. Overall, China's domestic ozone pollution is affected significantly by foreign anthropogenic emissions, which is in part because although China emits large amounts of ozone precursors, its substantial NOx emissions suppress

  15. Population-specific life histories contribute to metapopulation viability

    Restoration efforts can be improved by understanding how variations in life-history traits occur within populations of the same species living in different environments. This can be done by first understanding the demographic responses of natural occurring populations. Population viability analysis continues to be useful to species management and conservation with sensitivity analysis aiding in the understanding of population dynamics. In this study, using life-table response experiments and elasticity analyses, we investigated how population-specific life-history demographic responses contributed to the metapopulation viability of the Federally threatened Pitcher's thistle (Cirsium pitcheri). Specifically, we tested the following hypotheses: (1) Subpopulations occupying different environments within a metapopulation have independent demographic responses and (2) advancing succession results in a shift from a demographic response focused on growth and fecundity to one dominated by stasis. Our results showed that reintroductions had a positive contribution to the metapopulation growth rate as compared to native populations which had a negative contribution. We found no difference in succession on the contribution to metapopulation viability. In addition, we identified distinct population-specific contributions to metapopulation viability and were able to associate specific life-history demographic responses. For example, the positive impact of Miller High Dunes population on the metapopulation growth rate resulted from high growth contributions, whereas increased time of plant in stasis for the State Park Big Blowout population resulted in negative contributions. A greater understanding of how separate populations respond in their corresponding environment may ultimately lead to more effective management strategies aimed at reducing extinction risk. We propose the continued use of sensitivity analyses to evaluate population-specific demographic influences on

  16. The contribution of genetics and environment to obesity.

    Albuquerque, David; Nóbrega, Clévio; Manco, Licínio; Padez, Cristina

    2017-09-01

    Obesity is a global health problem mainly attributed to lifestyle changes such as diet, low physical activity or socioeconomics factors. However, several evidences consistently showed that genetics contributes significantly to the weight-gain susceptibility. A systematic literature search of most relevant original, review and meta-analysis, restricted to English was conducted in PubMed, Web of Science and Google scholar up to May 2017 concerning the contribution of genetics and environmental factors to obesity. Several evidences suggest that obesogenic environments contribute to the development of an obese phenotype. However, not every individual from the same population, despite sharing the same obesogenic environment, develop obesity. After more than 10 years of investigation on the genetics of obesity, the variants found associated with obesity represent only 3% of the estimated BMI-heritability, which is around 47-80%. Moreover, genetic factors per se were unable to explain the rapid spread of obesity prevalence. The integration of multi-omics data enables scientists having a better picture and to elucidate unknown pathways contributing to obesity. New studies based on case-control or gene candidate approach will be important to identify new variants associated with obesity susceptibility and consequently unveiling its genetic architecture. This will lead to an improvement of our understanding about underlying mechanisms involved in development and origin of the actual obesity epidemic. The integration of several omics will also provide insights about the interplay between genes and environments contributing to the obese phenotype.

  17. A Group Contribution Method for Estimating Cetane and Octane Numbers

    Much of the research on advanced biofuels is devoted to the study of novel chemical pathways for converting nonfood biomass into liquid fuels that can be blended with existing transportation fuels. Many compounds under consideration are not found in the existing fuel supplies. Often, the physical properties needed to assess the viability of a potential biofuel are not available. The only reliable information available may be the molecular structure. Group contribution methods for estimating physical properties from molecular structure have been used for more than 60 years. The most common application is estimation of thermodynamic properties. More recently, group contribution methods have been developed for estimating rate dependent properties including cetane and octane numbers. Often, published group contribution methods are limited in terms of types of function groups and range of applicability. In this study, a new, broadly-applicable group contribution method based on an artificial neural network was developed to estimate cetane number research octane number, and motor octane numbers of hydrocarbons and oxygenated hydrocarbons. The new method is more accurate over a greater range molecular weights and structural complexity than existing group contribution methods for estimating cetane and octane numbers.

    Argentine population genetic structure was examined using a set of 78 ancestry informative markers (AIMs) to assess the contributions of European, Amerindian, and African ancestry in 94 individuals members of this population. Using the Bayesian clustering algorithm STRUCTURE, the mean European contribution was 78%, the Amerindian contribution was 19.4%, and the African contribution was 2.5%. Similar results were found using weighted least mean square method: European, 80.2%; Amerindian, 18.1%; and African, 1.7%. Consistent with previous studies the current results showed very few individuals (four of 94) with greater than 10% African admixture. Notably, when individual admixture was examined, the Amerindian and European admixture showed a very large variance and individual Amerindian contribution ranged from 1.5 to 84.5% in the 94 individual Argentine subjects. These results indicate that admixture must be considered when clinical epidemiology or case control genetic analyses are studied in this population. Moreover, the current study provides a set of informative SNPs that can be used to ascertain or control for this potentially hidden stratification. In addition, the large variance in admixture proportions in individual Argentine subjects shown by this study suggests that this population is appropriate for future admixture mapping studies.

    The shrink in feature sizes enabled by EUV lithography introduces a regime where stochastic limits to resolution can manifest in the form of line edge roughness (LER) for line/space patterns and local critical dimension uniformity (LCDU) for contact/holes. To meet increasing tolerances on edge placement error (EPE) and suppression of stochastic effects, an understanding of EUV mask contributions on lithographic patterning variability is essential. The work here explores stochastic noise originating from the mask patterning process and attempts to quantify its contributions towards on-wafer LCDU. A semiempirical approach was used to statistically decompose the mask variability component from the measured LCDU and provide a first-order understanding of the mask's impact on wafer. Taking a more direct approach, a one-to-one correlation of local CD variation between mask and wafer was also experimentally shown, presenting the possibility for predicting the contributions and impact of mask LCDU on wafer prior to exposure.

    2017-01-01

    BACKGROUND: Clinical recommendations to limit gestational weight gain (GWG) imply high GWG is causally related to adverse outcomes in mother or offspring, but GWG is the sum of several inter-related complex phenotypes (maternal fat deposition and vascular expansion, placenta, amniotic fluid...... and fetal growth). Understanding the genetic contribution to GWG could help clarify the potential effect of its different components on maternal and offspring health. Here we explore the genetic contribution to total, early and late GWG. PARTICIPANTS AND METHODS: A genome-wide association study was used...... to identify maternal and fetal variants contributing to GWG in up to 10 543 mothers and 16 317 offspring of European origin, with replication in 10 660 mothers and 7561 offspring. Additional analyses determined the proportion of variability in GWG from maternal and fetal common genetic variants...

    An atmospheric general circulation model including the atmospheric sulfur cycle has been used to investigate the impact of aircraft sulfur emissions on the global sulfur budget of the atmosphere. The relative contribution from aircraft sulfur to the atmospheric sulfate burden is larger than the ratio between aircraft emissions and surface emissions due to the calculated long turn-over time of aircraft sulfate (about 12 days). However, in terms of the sulfate mass balance, aircraft emissions are small, contributing about 1% of the total sulfate mass north of 40 deg C where the aircraft emissions are largest. Despite this small contribution to sulfate mass, the aircraft emissions could potentially significantly enhance the background number concentration of aerosol particles. Based on the model calculations the increased stratospheric background aerosol mass observed during the last decades can not be explained by increased aircraft sulfur emissions 50 refs, 9 figs, 4 tabs

  3. Johannes Kepler and his contribution to Applied Mathematics

    Science.gov (United States)

    Pichler, Franz

    The worldwide renown of Johannes Kepler is based above all on his contribution to astronomy. The 3 Kepler's Laws relating to the planets are well known and will ensure that his name is remembered by future generations. Besides his astronomical work, Kepler also made important contributions in the fields of theology, physics, phylosophy and mathematics. The actual paper discusses the advances by Kepler in the application of mathematics to the solution of "real life problems". The author made a concise account of some of the disciples by Kepler: Klug, Wieleitner, Caspar, Hammer, paying particular attention to works published by Kepler while he was living in Linz (1612-1628). The Kepler's contribution to applied mathematics is an example supremely worthy of emulation, the author concludes.

  6. The Contribution of Neanderthals to Phenotypic Variation in Modern Humans.

    2017-10-05

    Assessing the genetic contribution of Neanderthals to non-disease phenotypes in modern humans has been difficult because of the absence of large cohorts for which common phenotype information is available. Using baseline phenotypes collected for 112,000 individuals by the UK Biobank, we can now elaborate on previous findings that identified associations between signatures of positive selection on Neanderthal DNA and various modern human traits but not any specific phenotypic consequences. Here, we show that Neanderthal DNA affects skin tone and hair color, height, sleeping patterns, mood, and smoking status in present-day Europeans. Interestingly, multiple Neanderthal alleles at different loci contribute to skin and hair color in present-day Europeans, and these Neanderthal alleles contribute to both lighter and darker skin tones and hair color, suggesting that Neanderthals themselves were most likely variable in these traits.

    Full Text Available We investigate a previously overlooked bottom quark contribution to the spin-dependent cross section for Dark Matter (DM scattering from the nucleon. While the mechanism is relevant to any supersymmetric extension of the Standard Model, for illustrative purposes we explore the consequences within the framework of the Minimal Supersymmetric Standard Model (MSSM. We study two cases, namely those where the DM is predominantly Gaugino or Higgsino. In both cases, there is a substantial, viable region in parameter space (mb˜−mχ≲O(100 GeV in which the bottom contribution becomes important. We show that a relatively large contribution from the bottom quark is consistent with constraints from spin-independent DM searches, as well as some incidental model dependent constraints.

    Full Text Available Turkish female scientists generally work for universities. Reckoning from 2009, there are 48861 female academicians, 25% of which are professors. Unfortunately we do not have a totalitarian study about Turkish female academicians and so do not know their backgrounds, their struggles to become scientists, their contributions to sciences as well as why they prefer some fields. This article tries to evaluate the situation of female Turkish academicians from the beginning to today in respect of their contributions to sciences. For this purpose it is based on the doctorate thesis called “Turkish Female Academicians and their Contributions to Sciences” by trying to update the statistics as soon as possible. The women who were studied were limited to the ones who were given TUBA (The Turkish Academy of Sciences and TUBITAK (The Scientific and Technological Research Council of Turkey Awards

  11. Anaerobic Contribution Determined in Swimming Distances: Relation with Performance

    Eduardo Z. Campos

    2017-10-01

    Full Text Available Total anaerobic contribution (TAn can be assessed by accumulated oxygen deficit, and through sum of glycolytic and phosphagen contribution which enable the evaluation of TAn without influences on mechanical parameters. However, little is known about the difference of TAn within swimming distances. Therefore, the objectives of the present study were to determine and compare the TAn in different performances using the backward extrapolation technique and amount of lactate accumulated during exercise, and relate it with swimming performance. Fourteen competitive swimmers performed five maximal front crawl swims of 50, 100, 200, 400, and 800 m. The total phosphagen (AnAl and glycolytic (AnLa contributions were assumed as the fast component of post-exercise oxygen consumption (EPOCFAST and amount of blood lactate accumulated during exercise, respectively. TAn was the sum of AnAl and AnLa. Significantly lower values of AnLa were observed in the 800 m (p < 0.01 than other distances. For AnAl, the 50 m performance presented the lowest values, followed by 100 and 800 m (p < 0.01. The highest values of AnAl were observed in the 200 and 400 m (p > 0.13. The TAn was significantly higher in the 200 and 400 m performances than observed at 50 and 800 m (p < 0.01. Anaerobic contributions were correlated with 50, 100, 200, and 400 m performances (p < 0.01. The AnAl contribution was not correlated with 400 m performance. Anaerobic parameters were not correlated with 800 m performance. In conclusion, the highest values of anaerobic contribution were observed in the 200 and 400 m distances. Moreover, TAn is important to performances below 400 m, and may be used in training routines.

    To estimate the contribution of the 3 energy systems to simulated judo matches. Twelve judo athletes (18 ± 1 y, 175.1 ± 5.3 cm, 74.3 ± 10.5 kg, 11.7% ± 1.5% body fat, 8 ± 2 y of practice) performed 5 combats with different durations (1, 2, 3, 4, and 5 min), against the same opponent, on different days and blinded to the duration. The estimated energy contributions for the oxidative, glycolytic, and ATP-PCr systems were calculated based on oxygen uptake (V̇O2) during activity, Delta of lactate, and the fast phase of excess V ̇ O2, respectively. Analysis of mixed models for repeated measures was used to compare the contribution of the 3 energy systems and different durations of judo matches, followed by a post hoc Bonferroni test. The oxidative system's contribution (70%) was higher than those of the glycolytic (8%; P < .001) and ATP-PCr (21%; P < .001) energy systems (in all durations), and the ATP-PCr contribution was higher than that of the glycolytic energy system (up to 3 min). In addition, during the match there was an increase in the oxidative (from 50% to 81%; P < .001), a decrease in the ATP-PCr (from 40% to 12%; P < .001), and maintenance of the glycolytic contributions (between 6% and 10%). There is a predominance of the oxidative system to supply the energy cost of judo matches from the first minute of combat up to the end, compared with the anaerobic systems.

  14. Contribution of Cation-π Interactions in Iminium Catalysis

    Directory of Open Access Journals (Sweden)

    2012-02-01

    Full Text Available Ab initio calculations were carried out for a benzyl-substituted iminium cation derived from (E-crotonaldehyde and a chiral imidazolidinone that was developed as an organocatalyst by MacMillan et al. At the MP2 level of theory it is predicted that the phenyl group is close to the iminium moiety in the most stable conformer, suggesting that the cation-π interaction contributes to the stabilization of this conformer. Energy decomposition analyses on model systems indicate that the electrostatic and polarization terms make significant contribution to the attractive interactions between the benzene ring and the iminium cation.

    2015-10-01

    The contributions of working memory and recollection to academic achievement are typically examined separately and most often with children who have learning difficulties. This study is the first to observe both types of memory in the same study and in typically developing children. Academic achievement focused on standardized assessments of math fluency, calculation, reading fluency, and passage comprehension. As noted in previous studies, working memory was associated with each assessed measure of academic achievement. Recollection, however, specifically contributed to math fluency and passage comprehension. Thus, recollection should be considered alongside working memory in studies of academic achievement.

  9. Export from Seagrass Meadows Contributes to Marine Carbon Sequestration

    KAUST Repository

    Duarte, Carlos M.

    2017-01-17

    Seagrasses export a substantial portion of their primary production, both in particulate and dissolved organic form, but the fate of this export production remains unaccounted for in terms of seagrass carbon sequestration. Here we review available evidence on the fate of seagrass carbon export to conclude that this represents a significant contribution to carbon sequestration, both in sediments outside seagrass meadows and in the deep sea. The evidence presented implies that the contribution of seagrass meadows to carbon sequestration has been underestimated by only including carbon burial within seagrass sediments.

  10. Electronic contribution to the oscillations of a gravitational antenna

    Branchina, Vincenzo; Rissone, Anna

    2004-01-01

    We carefully analyse the contribution to the oscillations of a metallic gravitational antenna due to the interaction between the electrons of the bar and the incoming gravitational wave. To this end, we first derive the total microscopic Hamiltonian of the wave-antenna system and then compute the contribution to the attenuation factor due to the electron-graviton interaction. As compared to the ordinary damping factor, which is due to the electron viscosity, this term turns out to be totally negligible. This result confirms that the only relevant mechanism for the interaction of a gravitational wave with a metallic antenna is its direct coupling with the bar normal modes.

    2017-05-01

    The contribution of the GOCE gravity gradients to regional gravity field solutions is investigated in this study. We employ radial basis functions to recover the gravity field on regional scales over Amazon and Himalayas as our test regions. In the first step, four individual solutions based on the more accurate gravity gradient components Txx, Tyy, Tzz and Txz are derived. The Tzz component gives better solution than the other single-component solutions despite the less accuracy of Tzz compared to Txx and Tyy. Furthermore, we determine five more solutions based on several selected combinations of the gravity gradient components including a combined solution using the four gradient components. The Tzz and Tyy components are shown to be the main contributors in all combined solutions whereas the Txz adds the least value to the regional gravity solutions. We also investigate the contribution of the regularization term. We show that the contribution of the regularization significantly decreases as more gravity gradients are included. For the solution using all gravity gradients, regularization term contributes to about 5 per cent of the total solution. Finally, we demonstrate that in our test areas, regional gravity modelling based on GOCE data provide more reliable gravity signal in medium wavelengths as compared to pre-GOCE global gravity field models such as the EGM2008.

  14. Drowning deaths among anglers: Are waders a contributing factor?

    Science.gov (United States)

    Petrass, Lauren A; Blitvich, Jennifer D; McElroy, G Keith

    2017-03-01

    Recreational fishing has been a popular activity for Australians over at least the past two centuries. While the use of waders for recreational fishing is widely adopted by participants, there is considerable speculation as to whether waders are contributing to fishing-related drowning deaths. This study involved a comprehensive search of peer-reviewed and grey literature to identify relevant information and a pilot investigation in a swimming pool to understand the accuracy of the currently available information. Extensive searching indicated that there is no published peer-reviewed evidence on the contribution of waders to drowning deaths, although the grey literature and personal communication with fishers offer a range of opinions, some that aim to discredit the claim that waders contribute to drowning, and others that support it. Improved understanding of the actual effect of waders based on biomechanical buoyancy principles and a pilot study of submersion in controlled conditions contributes to enhanced safety of fishers who choose to wear waders, dispels current myths and informs future studies of fishers wearing waders.

  1. Stellar contributions to the diffuse soft X-ray background

    Science.gov (United States)

    Bookbinder, J.; Avni, Y.; Golub, L.; Rosner, R.; Vaiana, G.

    1981-01-01

    One of the results of the EINSTEIN/C.f.A. X-ray stellar survey was a determination of the contribution of the disk stellar population to the galactic component of the diffuse soft (0.28 - 1.0 keV) X-ray background. This analysis employed both binned and unbinned nonparametric statistical methods that have been developed by Avni, et al. (1980). These methods permitted the use of the information contained in both the 22 detections and 4 upper bounds on the luminosities of 26 dM stars in order to derive their luminosity function. Luminosity functions for earlier stellar types are not yet developed. For these earlier stellar types, the median luminosities as determined by Vaiana, et al., are used (1981), which underestimates their contribution to the background. We find that it is the M dwarfs that dominate the disk population stellar contribution to this background. To calculate the contribution of the stellar sources to the background, simple models both for the spatial distribution of the stars and for the properties of the intervening interstellar medium are used. A model is chosen in which all stellar classes have the same functional form for their spatial distribution: an exponentially decreasing distribution above the galactic equatorial plane, and a uniform distribution within the galactic plane for a region of several kiloparsecs centered on the Sun.

  7. Sensitivity Analysis of Accumulated Savings in Defined Contribution Pension System

    Directory of Open Access Journals (Sweden)

    Mladen Latković

    2009-12-01

    Full Text Available In this article we analyze the effect of parameters in the standard model for calculation of accumulated savings in a defined contribution pension system. Three parameters affect accumulated savings in the standard model: saving duration, return of the pension fund and the growth in employee gross wage. By using a linear approximation we calculated marginal contributions for small changes in the parameters of the standard model and analyzed their relations for a set of referent parameters which are most suitable for the 2nd pillar pension system in Croatia. It is shown that the return of a pension fund has a major influence on accumulated savings, while the influence of the growth in employee gross wage is slightly smaller. Also, we calculated the influence of raising the contribution rate in the 2nd pillar on the accumulated savings in a simple scenario in which that rate is raised by equal amounts over the whole of a saving period. These results allow easier planning of pension insurance in the defined contribution system at a general level as well as at an individual level.

  11. Quantum Interference Contribution to the Dipole Moment of Diatomic Molecules.

    Science.gov (United States)

    Oliveira de Sousa, David Wilian; Nascimento, Marco Antonio Chaer

    2018-02-08

    The interference energy partitioning analysis method developed by our group and used to study the nature of the chemical bond was extended to partition the electric dipole moment in quasi-classical and interference contributions. Our results show that interference participates in charge displacement in polar molecules, providing, directly or indirectly, a relevant contribution for the total dipole moment. A linear correlation was found between the interference contribution of the dipole moment from the bond electron group, μ INT (bond), and the difference of electronegativity of the atoms which form the bond, ΔX AB . This interesting result reinforces the fact that electronegativity is not a property of an atom alone, but rather a property of the atom in the molecule and that ΔX AB can only be associated with that part of the total charge displacement resulting from the formation of the chemical bond. The partitioning of the total dipole moment into quasi-classical and interference contributions provides new insights about the reasons for the failure of the ΔX AB criterion in predicting the correct orientation of the dipole moment in several molecules. The results of the present work also bring additional evidence for the previously proposed mechanism of formation of polar bonds.

  1. Squark Mixing Contributions to CP violating phase gamma

    Energy Technology Data Exchange (ETDEWEB)

    Chang, Darwin; Chang, We-Fu; Keung, Wai-Yee; Sinha, Nita; Sinha, Rahul

    2001-09-17

    We investigate the possibility that the CP violation due to the soft supersymmetry breaking terms in squark mixing can give significant contributions to the various $\\gamma$ related parameters in B decays, different from those of the Standard Model. We derive the new limits on $(\\delta^u_12)_LL,LR,RR$ and on $(\\delta^d_23)_LL,LR,RR$ from the recent data on $D^0$--$\\barD^0$ oscillation as well as those on $B_s^0$--$\\barB_s^0$ oscillation. We show that, together with all the other constraints, the currents limits on these parameters still allow large contributions to the CP violating phases in $B_s^0$--$\\bar{B_s}^0$ as well as $D^0$--$\\barD^0$ oscillations which will modify some of the proposed measurements of $\\gamma$ parameters in CP violating B decays. However, the current constraints already dictate that the one-loop squark mixing contributions to various B decay amplitudes cannot be competitive with that of the Standard Model (SM), at least for those B decay modes which are dominated the tree level amplitudes within the SM, and therefore they are not significant in contributing to CP asymmetries in the corresponding B decays.
