  1. The computation of thick axisymmetric boundary layers and wakes around bodies of revolution

    Science.gov (United States)

    Markatos, N. C.

    The paper is concerned with the computational investigation of thick, axisymmetric, turbulent boundary layers and wakes around bodies of revolution. The procedures employed take full account of the influence of longitudinal and transverse surface curvatures and normal pressure gradients on the development of the boundary layer and wake, and also the viscous-inviscid interaction in the tail region of the body. The method makes it possible to calculate the static pressure and the velocity profiles along the body as well as the drag components; and it is applicable to both two- and three-dimensional situations, enabling, for example, the prediction of flows around ships' and submarines' hulls to be made. The application of the fully-elliptic calculation procedure to a body of revolution is described, and comparisons made between predictions and experimental measurements. The calculated axial variation of skin friction and pressure coefficient, and the velocity profiles are shown to be in fair agreement with experimental values.

    We present an analytical model of Doppler spectra in backscattering from arbitrary rough convex bodies of revolution rotating around their axes in the global Cartesian coordinate system. This analytical model is applied to analyse Doppler spectra in backscatter from two cones and two cylinders, as well as two ellipsoids of revolution. We numerically analyse the influences of attitude and geometry size of objects on Doppler spectra. The analytical model can give contribution of the surface roughness, attitude and geometry size of convex bodies of revolution to Doppler spectra and may contribute to laser Doppler velocimetry as well as ladar applications.

  3. Numerical simulation on drag reduction of revolution body through bionic riblet surface

    Institute of Scientific and Technical Information of China (English)

    2010-01-01

    Numerical simulations of flow fields on the bionic riblet and the smooth revolution bodies were performed based on the SST k-ω turbulence model in order to explain the mechanisms of the skin friction drag reduction, base drag reduction on the riblet surface, and flow control behaviors of riblet surface near the wall. The simulation results show that the riblet surface arranged on the rearward of the revolution body can reduce the skin friction drag by 8.27%, the base drag by 9.91% and the total drag by 8.59% at Ma number 0.8. The riblet surface reduces the skin friction drag by reducing the velocity gradient and turbulent intensity, and reduces the base drag by weakening the pumping action on the dead water region which behind the body of revolution caused by the external flow. The flow control behavior on boundary layer shows that the riblet surface can cut the low-speed flow near the wall effectively, and restrain the low-speed flow concentrating in span direction, thus weaken the instability of the low speed steaks produced by turbulent flow bursting.

    2004-01-01

    Drag reduction characteristics of supercavitating body of revolution was researched numerically with a bubble two-phase flow model embodied in commercial CFD code Fluent 6.0.The work included the effects of body shape on drag coefficient and supercavity sizes; supercavity control; drag coefficient Cd as a function of cavitation number; and the effect of the ratio of length L to diameter D on drag reduction rate. Research on drag reduction mechanism of supercavitation shows that supercavitation can reduce not only the friction drag coefficient but also the pressure drag coefficient. There may be a best combination among body shape, the ratio L/D, cavitation number, engineering feasibility and so on, which makes the drag reduction ratehighest.

  5. EXPERIMENTAL RESEARCH ON A SUPERCAVITATING SLENDER BODY OF REVOLUTION WITH VENTILATION

    Institute of Scientific and Technical Information of China (English)

    2002-01-01

    The behavior of supercavitating and cavitating flow around a conical body of revolution with and without ventilation at several angles of attack was studied experimentally. The hydrodynamical forces for a range of cavitation number were measured. Comparisons of the appearance and the hydrodynamical forces in condition of cavity with and without ventilation were made over the same range of the cavitation number, and a well agreement was obtained. The changes of the drag were especially studied. The experimental results showed that the drag of the model decreased with the presence of supercavity under the ventilation condition.

    2007-01-01

    Bionic non-smooth surfaces (BNSS) can reduce drag. Much attention has been paid to the mechanism of shear stress reduction by riblets. The mechanism of pressure force reduction by bionic non-smooth surfaces on bodies of revolution has not been, well investigated. In this work CFD simulation has revealed the mechanism of drag reduction by BNSS, which may work in three ways. First, BNSS on bodies of revolution may lower the surface velocity of the medium, which prevents the sudden speed up of air on the cross section. So the bottom pressure of the model would not be disturbed sharply, resulting in less energy loss and drag reduction. Second, the magnitude of vorticity induced by the bionic model becomes smaller because, due to the sculpturing, the growth of tiny air bubbles is avoided. Thus the large moment of inertia induced by large air bubble is reduced. The reduction of the vorticity could reduce the dissipation of the eddy. So the pressure force could also be reduced. Third, the thickness of the momentum layer on the model becomes less which, according to the relationship between the drag coefficient and the momentum thickness, reduces drag.

  7. INVESTIGATION OF VISCOUS FLOW FIELD AROUND AN APPENDED REVOLUTION BODY WITH GUIDE VANE PROPELLER

    Institute of Scientific and Technical Information of China (English)

    2000-01-01

    A RANS solver is presented to numerically simulate the viscous wake of an appended revolution body with guide vane propeller at the Reynolds number 107. The k-ε turbulence model together with wall function is used. The resulting finite difference equations are solved by SIMPLEC and ADI. The technique of rising up the bottom surface is presented to overcome radial contraction problem in Cartesian coordinate system. The three-dimensional body forces are separately adopted to model the affection of the guide vane and propeller. The detailed flow characteristics,especially the counter-swirl component generated by the guide vane in the propeller inflow, are numerically seized successfully. Compared with the experimental data, The computational axial velocity on the propeller disk plane comes up to engineering requirement.

  8. Nonlinear unsteady supersonic flow analysis for slender bodies of revolution: Theory

    1997-01-01

    Full Text Available We construct analytical solutions for the problem of nonlinear supersonic flow past slender bodies of revolution due to small amplitude oscillations. The method employed is based on the splitting of the time dependent small perturbation equation to a nonlinear time independent partial differential equation (P.D.E. concerning the steady flow, and a linear time dependent one, concerning the unsteady flow. Solutions in the form of three parameters family of surfaces for the first equation are constructed, while solutions including one arbitrary function for the second equation are extracted. As an application the evaluation of the small perturbation velocity resultants for a flow past a right circular cone is obtained making use of convenient boundary and initial conditions in accordance with the physical problem.

  9. Turbulent skin-friction drag on a slender body of revolution and Gray's Paradox

    Nesteruk, Igor [Institute of Hydromechanics, National Academy of Sciences of Ukraine, Kyiv (Ukraine); Cartwright, Julyan H E [Instituto Andaluz de Ciencias de la Tierra, CSIC-Universidad de Granada (Spain)

    2011-12-22

    The boundary layer on a slender body of revolution differs considerably from that on a flat plate, but these two cases can be connected by the Mangler-Stepanov transformations. The presented analysis shows that turbulent frictional drag on a slender rotationally symmetric body is much smaller than the flat-plate concept gives and the flow can remain laminar at larger Reynolds numbers. Both facts are valid for an unseparated flow pattern and enable us to revise the turbulent drag estimation of a dolphin, presented by Gray 74 years ago, and to resolve his paradox, since experimental data testify that dolphins can achieve flow without separation. The small values of turbulent skin-friction drag on slender bodies of revolution have additional interest for further experimental investigations and for applications of shapes without boundary-layer separation to diminish the total drag and noise of air- and hydrodynamic hulls.

    1989-01-01

    Low speed wind tunnel drag force measurements were taken on a laminar flow body of revolution free of support interference. This body was tested at zero incidence in the NASA Langley 13 in. Magnetic Suspension and Balance System (MSBS). The primary objective of these tests was to substantiate the drag force measuring capabilities of the 13 in. MSBS. The drag force calibrations and wind-on repeatability data provide a means of assessing these capabilities. Additional investigations include: (1) the effects of fixing transition; (2) the effects of fins installed in the tail; and (3) surface flow visualization using both liquid crystals and oil flow. Also two simple drag prediction codes were used to assess their usefulness in estimating overall body drag.

  12. Moralized Hygiene and Nationalized Body: Anti-Cigarette Campaigns in China on the Eve of the 1911 Revolution

    2013-03-01

    Full Text Available Western knowledge about the injurious effects of cigarette smoking on smokers’ health appeared in the late nineteenth century and was shaped by both the Christian temperance movement and scientific developments in chemistry and physiology. Along with the increasing import of cigarettes into China, this new knowledge entered China through translations published at the turn of the twentieth century. It was reinterpreted and modified to dissuade the Chinese people from smoking cigarettes in two anti-cigarette campaigns: one launched by a former American missionary, Edward Thwing, in Tianjin, and a second by progressive social elites in Shanghai on the eve of the 1911 Revolution. By examining the rhetoric and practice of the campaigns, I argue that the discourse of hygiene they deployed moralized the individual habit of cigarette smoking as undermining national strength and endangering the future of the Chinese nation, thus helping to construct the idea of a nationalized body at this highly politically charged moment.

    The Ptolemaic system of the universe, with the earth at the center, had held sway since antiquity as authoritative in philosophy, science, and church teaching. Following his observations of the heavenly bodies, Nicolaus Copernicus (1473-1543) abandoned the geocentric system for a heliocentric model, with the sun at the center. His remarkable work, On the Revolutions of Heavenly Spheres, stands as one of the greatest intellectual revolutions of all time, and profoundly influenced, among others, Galileo and Sir Isaac Newton.

  15. High Reynolds number flows about bodies of revolution with application to submarines and torpedoes

    Science.gov (United States)

    Jimenez, Juan M.

    The work presented here is an investigation of the wake flow field over a DARPA SUBOFF submarine model at a large range of Reynolds numbers based on model length, 1.1x106 ≤ ReL ≤ 25 x 106, on the centerline of the wake for locations 3, 6, 9, 12, and 15 diameters downstream from the tail. The model is an axisymmetric body without appendages (fins) supported by a streamlined support. The support models the flow of a semi-infinite sail. The wake experimental results, obtained using Particle Image Velocimetry (PIV) and crossed hot-wires, provide qualitative and quantitative insight into the flow field created by a submarine. In addition, the pressure was measured at 45 different locations along the submarine model for three different Reynolds numbers, ReL = 1.1 x 10 6, 12 x 106, and 25 x 106. Also, PIV measurements were conducted in the wake of the sail attached to a DARPA SUBOFF submarine model at ReL = 93.6 x 10 3. Four different yaw angles, 6 ≤ alpha ≤ 17, were investigated yielding insights into the behavior of the junction/hull and sail tip vortices. For all Reynolds numbers studied, the mean velocity distribution attains self-similarity at distances between 3 and 6 diameters downstream for the side where the support is not located, and follows an exponential function as expected from similarity arguments. In contrast, the mean velocity distribution for the support side does not attain self similarity, and displays significant effects of the support wake and support/body junction flows. In addition, none of the Reynolds stress distributions of the flow attain self similarity. For the higher Reynolds numbers studied the presence of the support introduces an asymmetry into the wake which results in the overall decrease of radial and axial turbulence intensities for the support side. Also, the coefficient of pressure, CP, distribution along the top meridian line of the model, r/D > 0, is generally lower for ReL = 1.1 x 106 than that for ReL = 12 x 10 6 and 25

    Low-speed wind tunnel drag force measurements were taken on a laminar flow body of revolution free of support interference. This body was tested at zero incidence in the NASA Langley 13 inch Magnetic Suspension and Balance System (MSBS). The primary objective of these tests was to substantiate the drag force measuring capabilities of the 13 inch MSBS. A secondary objective was to obtain support interference free drag measurements on an axisymmetric body of interest. Both objectives were met. The drag force calibrations and wind-on repeatability data provide a means of assessing the drag force measuring capabilities of the 13 inch MSBS. The measured drag coefficients for this body are of interest to researchers actively involved in designing minimum drag fuselage shapes. Additional investigations included: the effects of fixing transition; the effects of fins installed in the tail; surface flow visualizations using both liquid crystals and oil flow; and base pressure measurements using a one-channel telemetry system. Two drag prediction codes were used to assess their usefulness in estimating overall body drag. These theoretical results did not compare well with the measured values because of the following: incorrect or non-existent modeling of a laminar separation bubble on the body and incorrect of non-existent estimates of base pressure drag.

    The incompressible Navier-Stokes equations are numerically solved for steady flow around an ogive-cylinder (fineness ration 4.5) at angle of attack. The three-dimensional vortical flow is investigated with emphasis on the tip and the near wake region. The implicit, finite-difference computation is performed on the CRAY X-MP computer using the method of pseudo-compressibility. Comparisons of computational results with results of a companion towing tank experiment are presented for two symmetric leeside flow cases of moderate angles of attack. The topology of the flow is discussed and conclusions are drawn concerning the growth and stability of the primary vortices.

    Full Text Available Change and continuity are characteristics of human history. Strategic change in any society has significant impacts that becomes reference points for similar transformation in the near future. Fundamentally, the numerous internal upheavals that characterized North Africa and Middle East that culminated in a change of government in these countries has raised fundamental question about subject of change and revolution. Such questions include: is every change a revolution and does every revolution culminate in a change? What are the distinguishing features of change and the significance of such change for contemporary international politics? Using secondary data derived from books, and journals, the paper therefore examines the revolution and change in international politics drawing from historical examples of America and France Revolution. Also, noting the causes and implications of these of revolution on International Relations. It also seeks to distinguish between socio-political upheaval and internal disruptions that may culminate in change from revolution, that is, a vital change that affects institution, structure and value system of a society. The paper recommends a cautious use of the term revolution from change of government.

    Full Text Available A perspective on the very human process by which scientific paradigms change can help point the path forward in any science, or in an applied science, such as Structural Engineering. Understanding this process of change, we can examine earthquake engineering, seismic building codes and theories of structural engineering for earthquake loads. When we take this perspective, we recognize that Structural Engineering for earthquake resistance is in the midst of a number of revolutions, from paradigms embodied in current building codes in which earthquake demands are associated with forces, to a new paradigm in which earthquake demands are re-envisioned as resulting from structural displacements or drift. The new paradigm is embodied in the current national standard for the seismic rehabilitation of existing structures, ASCE 41 [2] and the emerging standards for performance-based earthquake engineering (PBEE. Associated with this is the shift from design oriented towards life-safety to design for a range of performance objectives, such as life-safety, damage reduction, or immediate occupancy. With this perspective, we further recognize deficiencies in research and development. We have failed to systematically use the experimental and computational tools we possess to fill in the gaps of scientific knowledge. We have not developed and deployed appropriate frameworks to collect and share ideas and results. As one example, the formulation of performance-based codes now outstrips the knowledge-base needed to ensure that structures designed by the new tools will meet their performance objectives.

    With a focus on the problem of bionic jet drag reduction , a bionic jet surface model is presented by using the jet flow of shark cheeks as the prototype .Based on the orthogonal test design method , this paper goes into detail about numerical simulations by making a comparison between bodies of revolution of a bionic annular jet flow sur -face ( BRBAJFS ) and smooth bodies of revolution with the SST k-ωturbulence model .The results prove that BRBAJFS has obvious drag-reduction and energy-saving effects .The highest energy saving efficiency can be 262 and the corresponding rate of drag reduction is 27.74%.The jet velocity has the most important impact on energy saving efficiency and it has a linear relation with the energy saving efficiency , i.e., the energy saving efficiency will decrease with an increase in the jet velocity .Furthermore, the position of the jet hole has the greatest impact on the total resistance .When the jet hole is far away from the bottom of the bodies of revolution , the drag reduction effi-ciency will increase and BRBAJFS decreases the viscous friction resistance by decreasing the velocity gradient of the wall and increasing the area of counterblows .There can also be a decrease in the pressure drag resulting from the jet fluid complementing the bottom of the bodies of revolution fluid .%针对仿生射流表面减阻问题,以鲨鱼鳃部射流为原型,建立仿生射流表面模型,采用正交试验设计法,利用SST k-ω湍流模型对仿生环形射流表面旋成体与光滑旋成体进行数值模拟。结果表明:旋成体环形射流表面具有减阻节能效果,最高节能效率达262,此时的减阻率为27.74%;射流速度对节能效率影响最大,射流速度与节能效率呈线性关系,随着射流速度增大,节能效率减小,射流孔位置对总阻力的影响最大,随着射流孔远离旋成体底部,减阻率增大。旋成体环形射流表面通过减小壁面的速度梯

    2016-01-01

    Full Text Available Phenomenon of transdisciplinarity was put into the fore of analysis rather recently. In the article an attempt is made to find out whether it is possible to attribute this phenomenon not only to a science (or even non-classical post-non-classical of the 21st century, or we have here the case where some scientific realities come to the attention of researchers with certain delay and has its value for the culture in general? It is possible to judge even the emergence of a kind of cognitive revolution affecting both science culture. We need to find out what is meant by a transdisciplinarity, and how it differs from the inter- or multiransdisciplinarity. In the study the method of historical reconstruction, combining elements of presentism and antiqurism, was implemented. This method allows us to interpret historical events in the context of a specific level of knowledge, and at the same time to evaluate them in terms of modern ideas related to transdisciplinarity, inter- and multidisciplinarity. System-structural method , focused on an integrated analysis of the dynamics of development of cognitive processes in culture was implied as well, and the method of comparative analysis, which is aimed at comparing different but conceptually similar processes in various areas of conceptual art practice. It is in the framework of (disciplinary based paradigm adopted a tacit agreement among scientists about the validity and effectiveness of research methods and techniques of inquiry. Within the (disciplinary based paradigm, which presupposes certain fundamental principles, goals, and certain values shared by the scientific community, the novel sprouts of radical ideas once emerge. The scientific revolution here means a radical revision of the admissibility of accepted and proven methods, goals and values that are common to the members of the scientific community. Typically, new theories and concepts proposed and already mastered new scientific community

    In this work, a hybrid formulation is established for bodies of revolution, based on the equation of Fourier series for the discontinuous finite element method, analogous to the one that exists in the classical finite element method. Furthermore, a methodology to analyse the prevention of fragile fracture in pressure vessel of pressurized water reactors is presented. The results obtained suggest that careful analysis must be made for non symmetric refrigeration. (author)

    Full Text Available In this study, humor and the confused feelings of overwhelming happiness, fear, and uncertainty intertwine to reflect Tunisians’ attitudes, beliefs, feelings, and experiences in the aftermath of the revolution. The study adopts a blended netnography/ethnography approach to data collection and analysis. My original data consist of 2 hrs of recorded discussions of 60 Tunisian students and a total of 300 online humorous posts collected from the social network Facebook (FB. The data revealed that Tunisians interacting via FB used two main types of situational humor: Third party insult and Alternate reality. These two types of humor were found to be associated with a variety of psychological and social functions and to serve as effective interpersonal strategies to construct group cohesion, strengthen shared attitudes and beliefs, and develop relational identity.

This note sheds new light on these contrasting experiences in the histories of England and France by looking at the evolution of real consumer prices...... to maintain a decent living, and often had to cut consumption to make ends meet. The exercise conducted in the present paper gives a quantitative and economic underpinning to the notion that the French revolution did not arise out of nowhere, but rather had its roots in centuries of hardship amongst working...

  9. Silicon: Child and Progenitor of Revolution

    Science.gov (United States)

    Cahn, R. W.

    Antoine Lavoisier, the pioneering French chemist who (together with Joseph Priestley in England) identified oxygen as an element and gave it its name, in 1789 concluded that quartz was probably a compound with an as-yet undiscovered but presumably extremely common element. That was also the year in which the French Revolution broke out. Five years later, the Jacobins accused Lavoisier of offences against the people and cut off his head, thereby nearly cutting off the new chemistry. It was not until 1824 that Jöns Berzelius in Sweden succeeded in confirming Lavoisier's speculation by isolating silicon. Argument at once broke out among the scientific elite as to whether the newly found element was a metal or an insulator. It took more than a century to settle that disagreement decisively: As so often, when all-or-nothing alternatives are fiercely argued, the truth turned out to be neither all nor nothing.

  10. Transatlantic Discourses of Freedom and Slavery during the English Revolution

    Directory of Open Access Journals (Sweden)

    2014-12-01

    Full Text Available Three themes in the discursive history of freedom and slavery during the English Revolution are explored here: the liberty of conscience, the liberty of the body, and the liberty of commerce. In the contests waged to define these liberties, contending factions of revolutionaries refashioned their opponents’ concepts of freedom as forms of bondage. Although explored in discrete fashion by historians, these discourses of religious, bodily, and commercial liberty hardly operated independently from one another.  Indeed, they became increasingly entangled as the Revolution reached its imperial turn (ca. 1649-1655, accompanied as it was by the rise of the slave trade in the West Indies and debates over the nature of “free trade” that circulated between England and the colonies.  Ultimately, to recover the entangled nature of these languages of liberty and their importance in the Revolution’s history of ideas, we must move beyond England itself and into the wider Atlantic world to grasp the material contexts that conditioned the Revolution’s discursive history.

    Andrews, C. D.; Cooper, C. E., Jr.

    1974-01-01

    An experimental aerodynamic investigation was conducted to provide data for studies to determine the criteria for simulating rocket engine plume induced aerodynamic effects in the wind tunnel using a simulated gaseous plume. Model surface and base pressure data were obtained in the presence of both a simulated and a prototype gaseous plume for a matrix of plume properties to enable investigators to determine the parameters that correlate the simulated and prototype plume-induced data. The test program was conducted in the Marshall Space Flight Center's 14 x 14-inch trisonic wind tunnel using two models, the first being a strut mounted cone-ogive-cylinder model with a fineness ratio of 9. Model exterior pressures, model plenum chamber and nozzle performance data were obtained at Mach numbers of 0.9, 1.2, 1.46, and 3.48. The exhaust plume was generated by using air as the simulant gas, or Freon-14 (CF4) as the prototype gas, over a chamber pressure range from 0 to 2,000 psia and a total temperature range from 50 to 600 F.

    2012-01-01

    The year 2012 marks the 50th anniversary of the publication of Thomas S. Kuhn's The Structure of Scientific Revolutions. Up until recently, the book's philosophical reception has been shaped, for the most part, by the debates and the climate in philosophy of science in the 1960s and 1970s; this new collection of essays takes a renewed look at this work. This volume concentrates on particular issues addressed or raised in light of recent scholarship and without the pressure of the immediate concerns scholars had at the time of the Structure's publication. There has been extensive research on all of the major issues concerning the development of science which are discussed in Structure, work in which the scholars contributing to this volume have all been actively involved. In recent years they have pursued novel research on a number of topics relevant to Structure's concerns, such as the nature and function of concepts, the complexity of logical positivism and its legacy, the relation of history to philosophy o...

    Kvasz, Ladislav

    2014-06-01

    The aim of the paper is to clarify Kuhn's theory of scientific revolutions. We propose to discriminate between a scientific revolution, which is a sociological event of a change of attitude of the scientific community with respect to a particular theory, and an epistemic rupture, which is a linguistic fact consisting of a discontinuity in the linguistic framework in which this theory is formulated. We propose a classification of epistemic ruptures into four types. In the paper, each of these types of epistemic ruptures is illustrated by examples from physics. The classification of epistemic ruptures can be used as a basis for a classification of scientific revolutions and thus for a refinement of our view of the progress of science.

    Xinhai Revolution, breaking out in the year of 1911, overthrew the tyranny of Qing Dynasty, set up Republic of China and meanwhile it enhanced the consciousness of democracy and the concept of republic and democratic. Since then China has transit preliminarily from traditional society to modern one, which was led to a modern-society-developing orbit and was proved to be a great era-significant national democratic revolution. Xinhai Revolution strengthened the social change of China and greatly influenced politics, economy, culture, education, media, regional cities, civil life and social space in Shandong to pave for modernization. Although met with many difficulties, the society in Shandong was filled with many turning points and headed for the way of developing Shandong during the period of Republic of China.

  20. Speculations on a Marxist theory of the Virtual Revolution

    Directory of Open Access Journals (Sweden)

    2005-01-01

    Full Text Available In contemporary discourses of business, it is often claimed that the post-Fordist global economy is revolutionary, radically transforming forms of social organisation and consciousness, and "virtuality" has come to signify the driver of this revolution. But how new is this development? Is it useful to call it a "revolution", using the term in the sense it had for Marx? Are there traces of a Marxist theory of virtuality, and how relevant is it today? We draw on chaos theory to identify important but shifting meanings for "virtuality" and "revolution" in Marx, to create a new terrain on which to better explore issues facing "digital labour" in the new environment.

  1. A Short (Personal) Future History of Revolution 2.0.

    Science.gov (United States)

    Spellman, Barbara A

    2015-11-01

    Crisis of replicability is one term that psychological scientists use for the current introspective phase we are in-I argue instead that we are going through a revolution analogous to a political revolution. Revolution 2.0 is an uprising focused on how we should be doing science now (i.e., in a 2.0 world). The precipitating events of the revolution have already been well-documented: failures to replicate, questionable research practices, fraud, etc. And the fact that none of these events is new to our field has also been well-documented. I suggest four interconnected reasons as to why this time is different: changing technology, changing demographics of researchers, limited resources, and misaligned incentives. I then describe two reasons why the revolution is more likely to catch on this time: technology (as part of the solution) and the fact that these concerns cut across social and life sciences-that is, we are not alone. Neither side in the revolution has behaved well, and each has characterized the other in extreme terms (although, of course, each has had a few extreme actors). Some suggested reforms are already taking hold (e.g., journals asking for more transparency in methods and analysis decisions; journals publishing replications) but the feared tyrannical requirements have, of course, not taken root (e.g., few journals require open data; there is no ban on exploratory analyses). Still, we have not yet made needed advances in the ways in which we accumulate, connect, and extract conclusions from our aggregated research. However, we are now ready to move forward by adopting incremental changes and by acknowledging the multiplicity of goals within psychological science.

    In a recently published article Sydney Brenner argued that the most relevant scientific revolution in biology at his time was the breakthrough of the role of "information" in biology.The fundamental concept that integrates this new biological "information" with matter and energy is the universal Turing machine and von Neumann’s self-reproducing machines.In this article we demonstrate that in contrast to Turing/von Neumann machines living cells can really reproduce themselves.Additionally current knowledge on the roles of noncoding RNAs indicates a radical violation of the central dogma of molecular biology and opens the way to a new revolution in life sciences.

    This paper introduces a new configuration of parallel manipulator call the Rotopod which is constructed from all revolute type joints. The Rotopod consists of two platforms connected by six legs and exhibits six Cartesian degrees of freedom. The Rotopod is initially compared with other all revolute joint parallel manipulators to show its similarities and differences. The inverse kinematics for this mechanism are developed and used to analyze the accessible workspace of the mechanism. Optimization is performed to determine the Rotopod design configurations which maximum the accessible workspace based on desirable functional constraints.

    2014-03-01

    Full Text Available This paper proposed to determine the Cartesian stiffness matrix and angular deflection analysis of revolute manipulator. The selected manipulator has rigid fixed link, two movable links and two rotary joints with joint stiffness coefficients are taken into account. The kinematic model of revolute joint manipulator has considered as a planar kinematic chain, which is composed by rigid fixed link and two revolute joints with clearance and deformable elements. The calculation of stiffness matrix depends on Jacobian matrix and change of configuration. The rotational joints are modeled as torsion springs with the same stiffness constant. The relative angular deflections are proportional to the actuated torques taken into account. The subject of this paper has to describe a method for stiffness analysis of serial manipulator. In the present work is to derive the stiffness matrix and angular deflection equations in the Robotic manipulator under the consideration of two-link optimum geometry model for rotary joint manipulator. The stiffness values are measured by displacements of its revolute links loaded by force.

    Full Text Available There is no innocent literature. Literature is made by love, by hate, by a woman, by an idea, by an injustice, by a hope, to praise or to criticize, but I think literature has never been isolated, pure, detached. [...] Literature cannot escape life and history (Manuel Cofiño Lopez, 1985: 9697. Cofiño Lopezs own literature is no exception. The clear contrast that he presents in The Last Woman and the upcoming battle between magic and reality, ignorance and culture, past and present has a purpose. The author raises the need to end with the old beliefs in order to progress.This inextricable link between magic and reality of the Revolution is present in several novels of the Cuban Revolution. It shows how the two interact, as well as how past and present intermingle. Moreover, we find that magic is present throughout, and is fully compatible with the Revolution. This does not make it erroneous to believe in the stories of Magic Realism. It is a mistake on the part of the revolution and those who write about it for attempting to deny people the magic of their superstitions and beliefs, since magic is not the enemy of progress. They are part of their lives and their culture, and are something that should be respected.

    CERN Document Server

    Chen, Xiang

    2000-01-01

    An analysis of the optical revolution in the context of early 19th century Britain. Far from merely involving the replacement of one optical theory by another, the revolution also involved substantial changes in instruments and the practices that surrounded them. People's judgements about classification, explanation and evaluation were affected by the way they used such optical instruments as spectroscopes, telescopes, polarisers, photometers, gratings, prisms and apertures. There were two instrumental traditions in this historical period, each of which nurtured a body of practice that exemplified how optical instruments should be operated, and especially how the eye should be used. These traditions functioned just like paradigms, shaping perspectives and even world views. Readership: Scholars and graduate students in the history of science, history of instrument, philosophy of science and science studies. Can also be used as a textbook in graduate courses on 19th century physics.

    Full Text Available Purpose: Industry 4.0 represents a special challenge for businesses in general and for SMEs in particular. The study at hand will examine companies´ awareness, readiness and capability to meet this challenge taking into account the special role of SMEs. Methodology: The results of nine studies dealing with this range of topics are examined in the framework of a systematic review and compared with regard to the objective of the study at hand. Findings: The review showed that, as a rule, there is an awareness concerning the relevance of the topic. The readiness and the capability to meet this challenge exist in parts; however, they strongly depend on the enterprise size. The smaller SMEs are, the higher the risk that they will become victims instead of beneficiaries of this revolution.Originality/value: Considering different studies concerning Industry 4.0 the article gives an insight into the dependence of the Industry 4.0 readiness in reference to the company size. This deepens the knowledge in adaption deficits German SME still have and opens different approaches for further research and action plans.

    2009-01-01

    Antony van Leeuwenhoek (1632-1723) created a surgical revolution by demonstrating, through a series of extraordinary discoveries, the presence of "strange little animals" under the microscope. His outstanding advances were directly related to his ability to grind better glasses, which enhanced magnification many times over previously manufactured glasses. His meticulous and dedicated observational skills were unmatched by anyone dealing with magnification at the time. The surgical revolution did not occur during Leeuwenhoek's time but more than a century later when the value of his findings was evidently recognized. Today Leeuwenhoek is considered the father of microscopy as well. It is particularly enlightening that for not being a scientist himself, he demonstrated all the good virtues of method and technique for which professional scientists are admired.

    Mexican physicians, faithful to their tradition of honor and patriotism, were present in the military and political events of the great Revolution, the began in 1910 and ended triumphantly in 1917. In the first phase, a Madero supporter and opposed to presidential reelection was doctor Francisco Vázquez Gómez, a specialist in otorhinolaryngology, Professor at the National Medical School and past President of our Academy of Medicine. The second phase of this Revolution, characterized by the struggle against the Huerta dictatorship and then by combats among revolutionary factions, also saw the intervention of many physicians and surgeons, such as senator Belisario Domínguez of Chiapas, a victim of dictatorial oppression. Among them were distinguished academicians such as doctors Rafael Silva of Mexico and Francisco Castillo Nájera of Durango. Likewise devoted nurses were in Carranza's group, while medical students enlisted in Zapata's forces. The last phase of the Revolution was dominated by the activities of the Constituent Congress in Querétaro, which promulgated the New Mexican Constitution. Among 223 elected representatives, 20 were physicians and two pharmacists (10%), who had an excellent participation in the different sessions. The new Constitution, sworn and signed on February 5, 1917, added social guarantees to individual guarantees already established by the Constitution of 1857.

  17. Walking Through the Revolution: A Spatial Reading of Literary Echoes

    2015-05-01

    Full Text Available This paper presents an embryo of a literary guide on the Carnation Revolution to be explored for educational historical excursions other than leisure and tourism. We propose a historical trail through the centre of Lisbon, city of the Carnation Revolution, called Walk through the Revolution. The trail aims to reinforce collective memory about the major events that occurred in the early moments leading to the coup. The trail is made up by nine places of rememberance, for which literary excerpts are suggested and which are supported by a digital research procedure. A set of seven fixed and observer-independent categories are used to analyse the literary contents of 23 literary works published up to 2013. These literary works refer to events that happened between the eve of April 25 and May 1, 1974. At the same time, literary descriptions are explored using a spatial approach in order to define the literary geography of the most iconic military actions and popular demonstrations that occurred in Lisbon and the surroundings. The literary geography and the cartography of the historical events are then compared. Data analysis and visualization benefit from the use of standardised and quantitative methods, including basic statistics and geographic information systems.

  18. The Media and the Making of the 2011 Egyptian Revolution

    Full Text Available While views may differ on the factors that made the 2011 Egyptian revolution possible, the role of mass media will remain undisputable. The Internet-based social networks caught the Mubarak regime by surprise, and the popular disillusionment with the ‘national’ media led the public to turn to private newspapers and satellite channels for keeping pace with the events. This paper examines the role of specific media during the 18 days of the 2011 Egyptian revolution – from 25 January to 11 February, 2011 – which we have divided into four parts. It discusses how these media contributed to the unfolding of events, conceptualized the protests and the demands of the public, and presented the actors that participated in or opposed the revolution. These points are addressed by discussing the content of the Facebook pages of the Sixth of April Movement and We Are All Khalid Said, as well as that of a private Egyptian newspaper, al-Shuruq, and the state-run newspaper al-Ahram.

  19. Visions of Revolutions: Microphysics and Cosmophysics in the 1930s

    CERN Document Server

    Kragh, Helge

    2011-01-01

    By 1930, at a time when the new physics based on relativity and quantum theory had reached a state of consolidation, problems of a foundational kind began to abound. Physicists began to speak of a new "crisis" and envisage a forthcoming "revolution" of a scale similar to the one in the mid-1920s. The perceived crisis was an issue not only in microphysics but also in cosmology, where it resulted in ambitious cosmophysical theories that transcended the ordinary methods of physics. The uncertain cognitive situation was, in some circles, associated to the uncertain political and moral situation. Did the problems of foundational physics demand a revolution in thinking that somehow paralleled the political revolutions of the time? I argue that although such ideas were indeed discussed in the 1930s, they were more rhetoric than reality. With the benefit of hindsight one can see that the perceived crisis was only temporary and not significantly related to social or ideological developments in the decade.

  20. Analysis of shells of revolution under earthquake motion

    Energy Technology Data Exchange (ETDEWEB)

    Sheinman, I.

    1986-02-01

    A generalization of the solution of any shell of revolution under earthquake motion and dynamic loading is presented. The equations of motion are derived with the aid of Hamilton's variational principle. A numerical solution is obtained by expending the variables in a Fourier series in the circumferential and in finite elements in the meridional direction. For earthquake analysis an exact method based on step-by-step direct integration and an approximate one involving the spectral velocity, are compared. A case of a nuclear containment under a horizontal earthquake is considered by both methods as an example. (orig.).

    Full Text Available The events during the “Autumn of People” have created sideration and stupor in the eyes and minds of the Western observers – who least expected the communist breakdown –, and consequently significant problems of interpretation and in deciphering the regime change in East-Central Europe. Clearly, with the “transition to democracy” process, the same observers have expressed disappointment and skepticism regarding the prospects of the countries of ECE unrestrainedly and uncritically embracing the model of Western-type consolidated liberal democracy: many have assessed that the exit from communism was not necessarily synonymous with the “return to Europe” tout court, for the very historical background, socio-economic and cultural preconditions and political conditions were not met so as to generate the complete and definitive triumph of liberal democracy in Europe. The present paper is an attempt at critically examining the regime change in 1988-1989 in East-Central Europe as an exponential case of “postmodern revolution”, following the analysis drawn by S.N. Eisenstadt in late ‘90. Breaking with the paradigm of the “Great Revolutions” (G. Pettee, 1989 lacked the characteristic features of a “classical revolution” (in the French or Russian sense, hence imposing a new species of revolution which was dominantly non-ideological, non-class-based, and non-violent, though achieving its central purpose, i.e. that of effectuating regime change. Concretely, this paper tries to introduce the 1988-1989 regime change in ECE in the general discussion of the defining and the characteristic features of a revolution, drawing extensively on the literature that preceded and followed the anus mirabilis, dedicated to the analysis of revolutions.

    After the sanitary disaster caused by the first months of the conflict, the Health service of the French armies undertook a true revolution. By 1918, it had become the most efficient of all the opposing armies. At the end of 1914, through the spacing out of the evacuating hospitals within the zone of the armies, the most efficient teams were placed as close as possible to the front. Injured soldiers were categorized at every step of the chain. Technical progress, especially in war surgery, pushed medicine into the moderne era.

    Full Text Available It is my main purpose to discuss in this paper three relevant topics concerned with Joseph Conrad's novel Under Western Eyes, namely: the author's view of revolution and anarchism and its relation with his Polish experience; how critical Conrad is of both autocracy and revolution and finally to discuss where in, the novel the writer is sympathetic to revolution. To begin with, let me mention some aspects of Conrad's Polish background. First of all, he was a Pole, born in the Russian-occupied Poland of 1857 as the son of one of the most spirited participants in the Polish National Comittee, and with a profound fear of Russian autocratic power in his blood. Politics, nationalism, the forces of imperialism and rebellion, were the first and deepest parts of his inheritance. Conrad's character was linked to the patriotic and nationalistic ardour of his father's nature, an idealist revolutionary, and to the conservatism of his uncle Tadeuz Bobrowski his guardian during youth. The duality of thought conditioned by Apollo Korzeniowski, the father, and Tadeuz Bobrowski made his character divided all his life long. The political approach in Under Western Eyes exemplifies the writer's duality of thought. In order to write this novel Conrad found uggestions in the writings of Russian novelists, mainly Dostoievsky's Crime and Punishment. Although the book fully justifies this assertion, the writer denies it and even affirmed in a letter to a friend that he had a "Russophobia", and that he did not like the works of the famous Russian writer.

Analyzing Lourié’s Eurasianist views specifically I argue that through his association with Eurasianism and his engagement with Neoclassicism Lourié did not abandon his revolutionary disposition; the means through which his revolutionism was pursued as well as the ideals that shaped it were merely redefined, while remaining firmly grounded in the Silver Age.

    1998-12-01

    The combinatorial immune response is restricted to jawed vertebrates with cartilaginous fishes being the lowest extant species to have the mechanism for diversification and an extensive panoply of immunoglobulins, T-cell receptors and MHC products. Here, we review the molecular events of the "big bang" or rapid evolutionary appearance of the functionally complete combinatorial immune system coincident with the appearance of ancestral jawed vertebrates, suggesting that this event was catalyzed by horizontal transfer of DNA processing systems. We analyze the nature and extent of variable and constant domain diversity among the distinct immunoglobulin sets of carcharhine sharks focusing upon the lambda-like light chains and the mu and omega heavy chains. The detection and isolation of natural antibodies from the blood of unimmunized sharks illustrates a surprising range of recognition specificities and the existence of polyspecificity suggests that the antibody-forming system of sharks offers unique opportunities for studies of immunological regulation. Although the homologies between shark and mammalian immunoglobulins are unequivocal, major differences in segmental gene organization present challenges to our understanding of basic immunological phenomena such as clonal restriction.

    Many dental practices today find themselves uncertain about the new social media universe, and in particular with how to relate to younger patients. The power of social networking is its immediate access to the word of mouth exchange of information, and the word of mouth avenue itself is recognized as the single most effective form of advertising. To tap into that phenomenon, begin by investing a small amount of time and effort to understand the basics of social networking. Sign up for Facebook and Twitter. First-hand experience interacting in a social network is the vital first step. The bottom line is simply this: To begin to understand this new arena of communication, you first have to join the conversation.

    Under certain conditions, a $(1+1)$-dimensional slice $\\hat{g}$ of a spherically symmetric black hole spacetime can be equivariantly embedded in $(2+1)$-dimensional Minkowski space. The embedding depends on a real parameter that corresponds physically to the surface gravity $\\kappa$ of the black hole horizon. Under conditions that turn out to be closely related, a real surface that possesses rotational symmetry can be equivariantly embedded in 3-dimensional Euclidean space. The embedding does not obviously depend on a parameter. However, the Gaussian curvature is given by a simple formula: If the metric is written $g = \\phi(r)^{-1} dr^2 + \\phi(r) d\\theta^2$, then $\\K_g=-{1/2}\\phi''(r)$. This note shows that metrics $g$ and $\\hat{g}$ occur in dual pairs, and that the embeddings described above are orthogonal facets of a single phenomenon. In particular, the metrics and their respective embeddings differ by a Wick rotation that preserves the ambient symmetry. Consequently, the embedding of $g$ depends on a real...

    2014-01-01

    Full Text Available Martin Amis uses the language of revolution to describe the newly altered social circumstances at the height of the sexual revolution in his semi-autobiographical novel The Pregnant Widow. The concept of a ‘language of revolution’ as well as second- and third-wave feminist scholarship is applied to a textual analysis of the novel. Amis’s brand of satire creates a sense of displacement and challenges existing perceptions about gender, culture and sexuality, exposing them as constructed and changeable norms. Moreover, it becomes clear that the author is skeptical about the benefits of the sexual revolution for either gender, and that he views its liberating aspects as unfulfilled, particularly for women. Given that Amis names one of his characters Scheherazade, evoking the legendary heroine of The Arabian Nights, the importance of storytelling in the novel is also examined and found to be a potentially redeeming force. Keywords: Martin Amis, sexual revolution, feminism, satire, gender, revolution

  18. Memories of Crisis: Bohr, Kuhn, and the Quantum Mechanical ``Revolution''

    2013-04-01

    ``The history of science, to my knowledge,'' wrote Thomas Kuhn, describing the years just prior to the development of matrix and wave mechanics, ``offers no equally clear, detailed, and cogent example of the creative functions of normal science and crisis.'' By 1924, most quantum theorists shared a sense that there was much wrong with all extant atomic models. Yet not all shared equally in the sense that the failure was either terribly surprising or particularly demoralizing. Not all agreed, that is, that a crisis for Bohr-like models was a crisis for quantum theory. This paper attempts to answer four questions: two about history, two about memory. First, which sub-groups of the quantum theoretical community saw themselves and their field in a state of crisis in the early 1920s? Second, why did they do so, and how was a sense of crisis related to their theoretical practices in physics? Third, do we regard the years before 1925 as a crisis because they were followed by the quantum mechanical revolution? And fourth, to reverse the last question, were we to call into the question the existence of a crisis (for some at least) does that make a subsequent revolution less revolutionary?

    Thomas Kuhn defined the characteristics of scientific revolutions based upon his knowledge of the first and second Scientific Revolutions. He concluded that such revolutions are the result of crises in science. However, he missed some important clues of how revolutions develop. Instead of looking at crises, we should look at the major trends in scientific and human thought prior to the revolutions and then we could gain a better understanding of how scientific revolutions emerge from the normal course of scientific evolution. Instead of defining revolutions by the crises that precede them, revolutions actually emerge from the successes of previous science while each revolution contains the seeds for the next revolution that follows. These seeds eventually grow into the crises that trigger revolutions. Under these circumstances, it can be shown that the space-time revolution of relativity theory was never completed, thus laying the foundations for the next revolution in science. Knowing this, we can determine if we have we already entered the pre-revolutionary period of the Third Scientific Revolution.

    Kenneth Wilson's Nobel Prize winning breakthrough in the renormalization group theory of phase transition and critical phenomena almost overlapped with the violent "cultural revolution" years (1966-1976) in China. An unexpected chance in 1972 brought the author of these lines close to the Wilson-Fisher є-expansion of critical exponents and eventually led to a joint paper with Lu Yu published entirely in Chinese without any English title and abstract. Even the original acknowledgment was deleted because of mentioning foreign names like Kenneth Wilson and Kerson Huang. In this article I will tell the 40-year old story as a much belated tribute to Kenneth Wilson and to reproduce the essence of our work in English. At the end, I give an elementary derivation of the Callan-Symanzik equation without referring to field theory.

    Full Text Available The question about the causes and actors of the February revolution can be understood only in the context of previous events. In this connection, of great importance is the analysis of the causes and circumstances of a strike wave that swept through Petrograd in October 1916. Up to 100 thousand strikers (together with locked-out workers were involved in these labor unrests that were accompanied by demonstrations and clashes with the police. In many ways (bread shortage as the main motivation, bakeshops pillage, spontaneity, suddenness, involvement of adolescents and women, Cossacks’ refusal to shoot into the crowd, solders’ desertion to the side of people, these events recall those of February 23–28, 1917. The American historians L. Haimson and E. Brian called them “a try-out of the February revolution”. Short information about these strikes is available in the papers of a number of Soviet authors; however, it is presented to some extent tendentiously, based on the desire to show the directing and organizational role of the Bolshevik party. In this regard, it seems important to restore the actual course of the events and give them an objective interpretation. The study shows that the October strikes were the first reaction of Petrograd workers to the emerging food crisis, whereas the February revolution was the reaction to the second, a much more acute phase of this crisis. The mechanism of these events was similar: in the both cases, famine was the major factor pushing for protests. In the both cases, protests were spontaneous and massive, externally similar to a hunger riot. The food crisis determined the army’s position as well: both in October and in February, Cossacks and soldiers sympathized with the starving population and refused to use weapons to crackdown demonstrators

For Central-Europeans, Westerners and the international community, the anti-communist revolutions of 1989 are related with 11/9, „the Fall of the Berlin Wall”, and „the Velvet Revolution”, while for Romanians, the same events are related with the bloody violent repression and confrontation, the faked „show trial” of Ceauşescu and his execution. While regime change in other former communist countries is related with terms and sintagms like transplacement, ruptforma, extrication or reforma pactada-ruptura pactada, pacted transition, „the four-player game theory model”, none of them is relevant for the Romanian case. He is trying to find answers for the questions „Why?” and „How?” related with so many events before, during and after 1989.

    We estimate the trend in average height of the population of the French province Orleans from 1715 to the beginning of the 19th century using data on recruits who were drafted either through a lottery system or through general conscription. After controlling for age, residence, and occupation, we find a general decline in the biological standard of living in the decades before the French Revolution. The results support a Ricardian-Malthusian interpretation of the causes of the French Revolution. In the debate 'Revolution de la misère ou de la prospérité' our findings support the side which argues that the French Revolution was a culmination of a long-lasting economic malaise during the final phases of the Ancien Régime.

    We live in a world made by science. How and when did this happen? This book tells the story of the extraordinary intellectual and cultural revolution that gave birth to modern science, and mounts a major challenge to the prevailing orthodoxy of its history. Before 1492 it was assumed that all significant knowledge was already available; there was no concept of progress; people looked for understanding to the past not the future. This book argues that everything changed with the discovery of America, which demonstrated that new knowledge was possible: indeed it introduced the very concept of "discovery", and opened the way to the invention of science. The first crucial discovery was Tycho Brahe's nova of 1572: proof that there could be change in the heavens. The telescope (1610) rendered the old astronomy obsolete. Torricelli's experiment with the vacuum (1643) led directly to the triumph of the experimental method in the Royal Society of Boyle and Newton. By 1750 Newtonianism was being celebrated throughout E...

    Nicholas Steno (1638 1686) compiled a notebook in 1659 when he was a student at the University of Copenhagen. Titled Chaos by Steno, it remains unstudied in English-speaking countries, despite having been translated in 1997. Chaos adds important insight into geology's place in the Scientific Revolution. It shows Steno disengaging from speculations about the cosmos based on the ruling paradigms of Aristotelian metaphysics and Cartesian misconceptions in favor of an empirical model based on the new mathematics of geometry applied to all of nature, from what we now would consider the atomic level, to the human body, and to the planet. Steno thereby earns heretofore unacknowledged credit for helping to establish the geometric definition of form that makes it possible to understand the evolution of the structure of organisms as well as of the planet.

    We consider the Kepler problem on surfaces of revolution that are homeomorphic to $S^2$ and have constant Gaussian curvature. We show that the system is maximally superintegrable, finding constants of motion that generalize the Runge-Lentz vector. Then, using such first integrals, we determine the class of surfaces that lead to block-regularizable collision singularities. In particular we show that the singularities are always regularizable if the surfaces are spherical orbifolds of revolution with constant curvature.

    Marcum, James A

    2015-01-01

    This new edition of Thomas Kuhn's Revolution marks the 50th anniversary of the publication of Kuhn's most influential work. Drawing on the rich archival sources at MIT, and engaging fully with current scholarship, James Marcum provides the historical background to the development of The Structure of Scientific Revolutions. Exploring the shift Kuhn makes from a historical to an evolutionary philosophy of science and examining Kuhn's legacy in depth, Marcum answers key questions: What exactly was Kuhn's historiographic revolution and how did it come about? Why did it have the impact it did? What will its future impact be for both academia and society? Marcum's answers build a new portrait of Kuhn: his personality, his pedagogical style and the intellectual and social context in which he practiced his trade. Thomas Kuhn's Revolution shows how Kuhn transcends the boundaries of the philosophy of science, influencing sociologists, economists, theologians and even policy makers and politicians. This is a comprehensi...

  13. Voigt's transformations and the beginning of the relativistic revolution

    2014-01-01

    In 1887 W. Voigt published a paper on the Doppler effect, which marked the birth of the relativistic revolution. In his paper Voigt derived a set of spacetime transformations by demanding covariance to the homogeneous wave equation in inertial frames, and this was an application of the first postulate of special relativity. Voigt assumed in his derivation the invariance of the speed of light in inertial frames, and this is the second postulate of special relativity. He then applied the postulates of special relativity to the wave equation 18 years before Einstein explicitly enunciated these postulates. Voigt's transformations questioned the Newtonian notion of absolute time for the first time in physics by suggesting that the absolute time should be replaced by the non-absolute time $t'=t-vx/c^2$. Unfortunately, Voigt's 1887 paper was not appreciated by most physicists of that time. Voigt's transformations do not form a group and are an example of the conformal symmetry of spacetime. In the present paper we e...

    Full Text Available By the late 1980s, Ceaușescu had transformed Romania into a police state. The uprising from december 1989 that led to Ceaușescu’s downfall began with some incidents in Timisoara on 16 of December. The demonstrations spread to Bucharest, and further to others cities of Romania. We aimed to treat in this paper the Romanian Revolution of 1989, a mixture of spontaneous general uprising and conspiracy against Ceaușescu organized by reform communists and disaffected elements of the Securitate and army. The perspective from which we have chosen to look at the event (and also to the road to the shock of december 1989 is through Dumitru Popescu’s memoirs. Dumitru Popescu, ex- vice president of the State Committee for Culture and Art and President of the Council of Socialist Culture and Education, was one of the creators of the Ceausescu’s ideology. He graduate the Party School of Social Sciences „A.A.

    2015-07-01

    Like most of the tools that enable modern life science research, the recent genome-editing revolution has its biological roots in the world of bacteria and archaea. Clustered, regularly interspaced, short palindromic repeats (CRISPR) loci are found in the genomes of many bacteria and most archaea, and underlie an adaptive immune system that protects the host cell against invasive nucleic acids such as viral genomes. In recent years, engineered versions of these systems have enabled efficient DNA targeting in living cells from dozens of species (including humans and other eukaryotes), and the exploitation of the resulting endogenous DNA repair pathways has provided a route to fast, easy, and affordable genome editing. In only three years after RNA-guided DNA cleavage was first harnessed, the ability to edit genomes via simple, user-defined RNA sequences has already revolutionized nearly all areas of biological science. CRISPR-based technologies are now poised to similarly revolutionize many facets of clinical medicine, and even promise to advance the long-term goal of directly editing genomic sequences of patients with inherited disease. In this review, we describe the biological and mechanistic basis for these remarkable immune systems, and how their engineered derivatives are revolutionizing basic and clinical research.

    Full Text Available This article presents to the readers in Latin America the thought of the Italian liberal writer and politician Piero Gobetti (Torino 1900–Paris 1926 who was a close friend of Antonio Gramsci and one of the main intellectual influences on the work of the marxist peruvian thinker José Carlos Mariátegui. His most relevant book, La Rivoluzione Libérale, was translated into Spanish only recently but —as Mariátegui understood— some of Gobetti's ideas are very relevant to an analysis of Latin American socialformations. His very original "movement oriented" liberalism was influenced by the Russian revolution as well as by philosophers like Georges Sorel, Gaetano Mosca, Benedetto Croce and Henri Bergson.Gobetti's major concern in politics was to promote the emergence of a new ruling class. For a better comprehension of his thought, Gobetti's ideas are here compared with those of Gramsci and Mariátegui.

    Full Text Available This paper unveils the revolutionary potential incarnated in the post-9/11 transformed figure of the cinematic zombie. It is my contention that zombies, through their cinematic (revolution, came to embody Deleuze and Guattari’s vision of the nomad war machine. Zombie films are used as a vehicle for addressing the tension between the hegemonic fear of the violent multitude in revolt and the counter-hegemonic liberatory potential of the rising masses. It is impossible to achieve a final resolution between these contradicting tendencies since the narrative structure of zombie films remains open-ended. The characteristics of the zombies and the meaning ascribed to them transform over time but they also maintain a continuity with a difference with the previous expressions of the monstrous. The monstrous characteristics which have pertained since George A. Romero’s paradigm shift in the 1960s (the zombifying contagion, violence and swarm attacks, joined with the new features appearing in the American zombie cinema of the new millennium, formulate a response to the manifest and latent violence of the State apparatus.

Western Christianity adjusted to modernity to justify the developments while Islam accepted it only to the extent of its capacity to authenticate the realities stated by the Qur’an. Orientalism, Occidentalism, and Islamism play impressive role in a variety of contexts today. Occidentalism in its popular variety helps to reinforce the identities. This study considers the power relationship between people and cultures. The roles and the identities are changing throughout history. Nowadays Islamic culture is one of popular subjects to study on. So, the Muslim world and revival of Islamic culture are the beginning of Occidentalism. Occidentalism is developed in the Orient in order to study the West from a non-Western World point of view. It can be referred as revival of identity (for isteghrab in Arab world by Hasan Hanafi or Talibanian or ISIS Occidentalists movements which stand for empowering Arab culture, Wahhabism or Salafism. All are revivalist movements to rapture Islamism as an ideology. This article tries to focus on the concept of Occidentalism in Iran after Iran Cultural Revolution.

Mushroom can serve as food, tonic, and as medicine thus make people healthier, fitter and happier. They have a cracking potential for generating great socioeconomic impact in human welfare at local, national and international level. With the help of allied mushroom farming we can easily tackle the problem of food for growing world population; reduce environmental pollution by bioconversion of huge organic wastes into mushrooms; recycle huge quantity of organic wastes to mushroom crops, biofertilizers, and biogas; restore damaged environment by mushroom mycelia through mycoforestry, mycoremediation, mycofiltration and mycopesticides in a zero emission fashion. They can be used to degrade radioactive industrial biocide wastes in an eco-friendly fashion. Since mushroom cultivation is an indoor agribusiness, it could have great economic impact by generating employment, income and functional food requirements for rural people especially in developing countries. How far mushroom cultivation can meet the functional food requirements; address the domestic food challenges, rising food prices and crisis vis a vis environmental sustainability will be thrust areas of this communication.

    This paper aimed to examine the anatomical revolution from Yilingaicuo (Correcting the Errors of Medicine) and Quantixinlun(Outline of Anatomy and Physiology) in late imperial China. As the cephalocentrism which the brain superintend human operation of the mind was diffused in China since 16th century, the cephalocentrism and the cardiocentrism had competed for the hegemony of anatomical conception. Because of the advent of Yilingaicuo and Quantixinlun, the cephalocentrism became the main stream in the anatomical conception. The supporters of the Wang Yangming's Xinxue(the Learning of Heart and Mind) argued that the heart was the central organ of perception, sensitivity, and morality of the human body in medicine since 16th century. Even reformist and revolutionary intellectuals like Tan sitong and Mao zedong who had supported the Wang Yangming's Xinxue embraced the cephalocentrism in the late 19th century and the early 20th century. May Fourth intellectuals had not obsessed metaphysical interpretation of human body any more in the New Culture Movement in 1910s. They regarded human body as the object of research and writing. The anatomy was transformed into the instrumental knowledge for mutilation of the body. Yilingaicuo challenged the traditional conception of body, and Chinese intellectuals drew interest in the anatomy knowledge based on real mutilation. Quantixinlun based on Western medicine fueled a controversy about anatomy. Though new knowledge of anatomy was criticized by traditional Chinese medical doctors from the usefulness and morality of anatomy, nobody disavowed new knowledge of anatomy from the institutionalization of Western medicine in medical school. The internal development of cephalocentrism and positivism had influence on anatomy in China since 16th century. The advent of Yilingaicuo and Quantixinlun provided the milestone of new anatomy, though both sides represented traditional Chinese medicine and Western medicine respectively. They

    Full Text Available Time is one of the major considerations throughout project management life cycle and can be regarded as one of the most important parameters of a project and the driving force of project success. Time delay is a very frequent phenomenon and is almost associated with nearly all constructing projects. However, little effort has been made to curtail the phenomenon, this research work attempts to identify, investigate, and rank factors perceived to affect delays in the Egyptian construction projects with respect to their relative importance so as to proffer possible ways of coping with this phenomenon. To achieve this objective, researcher invited practitioners and experts, comprising a statistically representative sample to participate in a structured questionnaire survey. Brain storming was taken into consideration, through which a number of delay factors were identified in construction projects. Totally, ninety-nine (99 factors were short-listed to be made part of the questionnaire survey and were identified and categorized into nine (9 major categories. The survey was conducted with experts and representatives from private, public, and local general construction firms. The data were analyzed using Relative Importance Index (RII, ranking and simple percentages. Ranking of factors and categories was demonstrated according to their importance level on delay, especially after 25/1/2011 (Egyptian revolution. According to the case study results, the most contributing factors and categories (those need attention to delays were discussed, and some recommendations were made in order to minimize and control delays in construction projects. Also, this paper can serve as a guide for all construction parties with effective management in construction projects to achieve a competitive level of quality and a time effective project.

    2010-01-01

    The turn of the XXth century witnessed a revolution in physics comparable to Isaac Newton’s discovery of the universal laws of mechanics and of gravitation three centuries earlier. The world required to be described in novel terms, as the immutable, deterministic view of our familiar universe had given way to a new world picture, one which featured chance, flux, and an incessant upsurge of waves of matter. Such a worldview was so radically new and counterintuitive that it gave rise to strong debates, to the effect that Albert Einstein himself tried to oppose it on the grounds that “God does not play dice”. In spite of the intense debates that accompanied its emergence, quantum mechanics quickly proved an incredibly efficacious new tool to understand and to predict a wide array of new phenomena. It was so successful that in no time it broke free from the environment of research labs to become part of daily life, making it possible, for example, to understand why some materials...

    Green Revolution made a substantial contribution to wheat yields worldwide in the 1960s and 1970s. It is of great importance to analyze the haplotype variation of Rht-D1, the Green Revolution gene, during wheat (Triticum aestivum L.) domestication and breeding to understand its evolution and function in wheat breeding history. In this study, the Rht-D1 and its flanking regions were sequenced and single nucleotide polymorphisms were detected based on a panel of 45 accessions of Aegilops tauschi , 51 accessions of landraces and 80 accessions of commercial varieties. Genetic diversity in the wild accessions was much higher than that in the varieties and higher than that reported previously. Seven haplotypes (Hapl I to Hapl VII) of Rht-D1 were identified and their evolutionary relationships were proposed. In addition to the wel-known Green Revolution al ele Rht-D1b, Hapl VII (an al ele Rht-D1k) was identified in early breeding varieties, which reduced plant height by 16%. The results suggested that Rht-D1k had been used in breeding before the Green Revolution and made a great contribution to wheat production worldwide. Based on the breeding history and molecular evidence, we proposed that the wheat Green Revolution in China and International Maize and Wheat Improvement Center (CIMMYT) occurred independently.

    2016-01-01

    We investigate the dynamical behavior of rings around bodies whose shapes depart considerably from that of a sphere. To this end, we have developed a new self-gravitating discrete element N-body code, and employed a local simulation method to simulate a patch of the ring. The central body is modeled as a symmetric (oblate or prolate) ellipsoid, or defined through the characteristic frequencies (circular, vertical, epicyclic) that represent its gravitational field. Through our simulations we explore how a ring's behavior -- characterized by dynamical properties like impact frequency, granular temperature, number density, vertical thickness and radial width -- varies with the changing gravitational potential of the central body. We also contrast properties of rings about large central bodies (e.g. Saturn) with those of smaller ones (e.g. Chariklo). Finally, we investigate how the characteristic frequencies of a central body, restricted to being a solid of revolution with an equatorial plane of symmetry, affect ...

  9. A departure from cognitivism: Implications of Chomsky's second revolution in linguistics.

    Schoneberger, T

    2000-01-01

    In 1957 Noam Chomsky published Syntactic Structures, expressing views characterized as constituting a "revolution" in linguistics. Chomsky proposed that the proper subject matter of linguistics is not the utterances of speakers, but what speakers and listeners know. To that end, he theorized that what they know is a system of rules that underlie actual performance. This theory became known as transformational grammar. In subsequent versions of this theory, rules continued to play a dominant role. However, in 1980 Chomsky began a second revolution by proposing the elimination of rules in a new theory: the principles-and-parameters approach. Subsequent writings finalized the abandonment of rules. Given the centrality of rules to cognitivism, this paper argues that Chomsky's second revolution constitutes a departure from cognitivism.

    The influence of Facebook in social life keeps constantly growing. Recently, the communication of information has been vital to the success of the Tunisian revolution, and Facebook was its main "catalyst." This study examines the key reasons that explain Facebook's contribution to this historical event, as perceived by Tunisian Internet users. To do so, we launched this study 5 days after the fall of the regime using an online questionnaire in which participants (N=333) first rated the importance of Facebook in the Tunisian revolution and then explained the reasons for their ratings. A cluster analysis based on the Euclidean distance between the most frequent words in the participants' text corpus (6,640 words), revealed three main clusters that we interpret as follows: 1: Facebook political function, 2: Facebook informational function, and 3: Facebook media platform function. It is likely that these factors reflect the dynamic of Tunisian cyberspace and the Tunisian Internet users' collective consciousness during the revolution.

    Full Text Available This chapter examines the role of food in the symbolic politics and practical agenda of the Black Panther Party (BPP, founded in the late 1960s in Oakland, California.  Situating hunger and the politics of food at the center of drives for racial justice, it argues that the BPP’s anti-hunger efforts and food-centered campaigns were driven by an implicit understanding of the power of food in battles over racialized definitions of personhood, a forum for both enforcing and resisting hegemonic authority.  From this vantage, the Panthers and their allies in the East Bay community utilized the Party’s popular food programs, specifically its Free Breakfast for School Children Program, as staging grounds to prepare for a revolutionary overthrow of the socio-economic order.  In addition to strengthening the physical bodies of African Americans to ensure their “survival pending revolution,” the food programs served a deeper organizing function by encouraging community members to come together to meet an immediate, practical need and, in doing so, to visualize themselves as part of a larger movement for change.  The Panthers’ subsequent demands for consumer rights and calls for conscientious consumption (both as purchasers and eaters of food highlighted the role of food politics in perpetuating racial injustice while demonstrating the capacity for food-related protest to challenge structures of hunger and patterns of widespread malnourishment.

    The bacterial flagellar motor is an ion-driven rotary machine in the cell envelope of bacteria. When we performed a bead assay, in which the cell body was affixed to a glass surface to observe the rotation of a truncated flagellum via the positioning of a 250 nm-diameter gold nanoparticle, we often observed that the filament motion consisted of two types of rotation: spin and revolution, which resulted in precession. Since the mechanism of flagella precession was unknown, we investigated it using numerical simulations. The results show that the precession occurred due to hydrodynamic interactions between the flagellum and the wall in the Stokes flow regime. We also developed a simple theory of the precession, which validity was confirmed by comparing with the simulation. The theory could be utilized to predict both the filament tilt angle and motor torque from experimental flagellar precession data. The knowledge obtained is important in understanding mechanical properties of the bacterial motor and hook.

    2015-02-01

    I respond to the critical comments by Martin Kusch and Ursula Klein on my account of the Chemical Revolution. I comment along three different lines: descriptive, explanatory, and normative. (1) I agree with Klein that Lavoisier did not introduce drastic changes in chemical ontology, but maintain that there was methodological incommensurability in the Chemical Revolution; in response to Kusch's view, I maintain that Lavoisier's victory was slow and incomplete. (2) Admitting that there were many causes shaping the outcome of the Chemical Revolution, including the convenience of Lavoisier's theoretical scheme and various complicated social factors, I still think that the general rise of compositionism was an important factor. (3) I defend my normative pluralist view on the Chemical Revolution, denying Kusch's argument that chemists had overwhelmingly good reasons to trust Lavoisier and his allies over the phlogistonists. Overall, I agree with Kusch that it would be desirable to have a good descriptive-normative sociological account of the Chemical Revolution, but I also think that it should be an account that allows for divergence in individuals' and sub-communities' self-determination.

  5. Studying revolutions in Cuban education: A need of teachers training at the university

    Full Text Available In Cuba, Revolution and education are overlapping processes, one might be impossible without the other. Three educational revolutions are identified and characterized in the paper; a definition for the term is given. Likewise, the role of teachers and educators contributing to the construction of socialism is discussed. After diagnosing pupils being trained as teachers of Marxism-Leninism and History, the lack of knowledge of the role of teachers and their contribution the educational program of the Revolution was revealed. This paper is aimed at describing the method of emotional commitment to paradigm of educators. This method helps to account the enrolment of professor of José Martí” College of Education in the task of doing a revolution in education and constructing socialism in Cuba. The novelty of the method is the revelation of the connection between landmarks and protagonists, a person who teachers’ trainees take as a paradigm in building their own personality and as the object of study in history of education research process they are carrying out.

  7. The dark side of the Scientific Revolution. The Biblical interpretation in Galileo Galilei and Isaac Newton

    Directory of Open Access Journals (Sweden)

    Francesco Fiorentino

    2015-11-01

    Full Text Available This contribution investigates a hidden and surely singular – but far from marginal – aspect of the Scientific Revolution of the 17th century, in other words the interpretation of the Holy Scriptures. First of all, this work analyzes the situation immediately before the advent of the fathers of the 17th Century Scientific Revolution like Galileo Galilei and Isaac Newton, starting from the Council of Trent. This reconstruction aims to throw light on the particular way that Galileo and Newton intended to approach the interpretation of the Holy Scriptures with respect to the main tendencies of the Catholic Reformation of biblical hermeneutics. Their way is important both in itself and in relation to the Scientific Revolution. In itself because Galileo and Newton elaborate original theories that are not entirely in agreement with the predominant views and that are decidedly no less interesting than their pure scientific theories. In relation to the Scientific Revolution because the interpretation of the Holy Scriptures is addressed in an original fashion by both Galileo and Newton, also with the intent of facilitating the spread and approval of their own scientific theories in their respective socio-cultural environments. The primacy of nature is not manifested only in contrast to and outside the book of Scriptures, but conditions the Book of Scriptures, locating it within a precise cultural perspective and religious sense that are by no means contrary to Galileo and Newton’s views.

    Saraga, M; Bourquin, C; Wykretowicz, H; Stiefel, F

    2015-02-11

    The human body is the object upon which medicine is acting, but also lived reality, image, symbol, representation and the object of elaboration and theory. All these elements which constitute the body influence the way medicine is treating it. In this series of three articles, we address the human body from various perspectives: medical (1), phenomenological (2), psychosomatic and socio-anthropological (3). This first article discusses four distinct types of representation of the body within medicine, each related to a specific epistemology and shaping a distinct kind of clinical legitimacy: the body-object of anatomy, the body-machine of physiology, the cybernetic body of biology, the statistical body of epidemiology.

    In this study, nanoparticles of various poorly water soluble compounds were prepared by wet milling that was carried out using a rotation/revolution mixer and zirconia balls. To be compared with Beads mill, rotation/revolution mixer has superior in very quick process (5 min) and needs very few amounts of zirconia balls (2.4 g) for pulverizing drugs to nanometer range. Phenytoin, indomethacin, nifedipine, danazol, and naproxen were selected as the standard poorly water soluble compounds. Various parameters of the rotation/revolution mixer were studied to decide the optimal pulverization conditions for the production of nanoparticles of the abovementioned compounds. The rotation/revolution speed, shape of the mixing vessel, amount of zirconia balls, and volume of the vehicle (methylcellulose solution) mainly affected the pulverization of the compounds. Using the mixer, phenytoin could be pulverized to nanoparticles within a few minutes. The particle size was confirmed by using a scanning electron microscope and a particle size analyzer. The crystallinity of the pulverized phenytoin particles was confirmed by X-ray diffractometry (XRD) and differential scanning calorimetry (DSC). It was observed that the pulverized phenytoin particles retained their crystallinity, and amorphous phenytoin was not detected. Particles of other poorly water soluble compounds were also reduced to the nanometer range by using this method.

  13. Eshche raz o probleme nauchniykh revolyutsij %t Once again about problems of scientific revolutions

    Science.gov (United States)

    Eremeeva, A. I.

    We state that revolutionary stages in the progress of scientific knowledge are real and determined by the complexity of science as a system of knowledge. The revolutionary character of the alteration of knowledge is defined as alteration with the non-observance of the principle of conformity. Such alterations may occur only in the modeling component of science in the frame of separate theories (is qualitative component explaining the nature of objects or mechanism of phenomena) as well as in the scientific picture of the world (SPW) as a whole. SPW is defined as a limitless extrapolation of reliable knowledge (that is, facts established by experimental and theoretical methods and always limited by the level of the development of the means of their acquirement). With time going, the SPW becomes a solid tradition. Sooner or later its fundamentals begin to conflict with the new scientific discoveries, which makes it necessary to change SPW. But as a more general world outlook is developed on the base of the prevailing SPW, SPW alterations usually provoke a great public resonance and meet with resistance, reluctance even outside the narrowly-specialized scientific community. This process that starts with the appearing of a new fundamental idea, causes the formally prevailing SPW breaking and ends by forming the base of the new SPW we do classify as the scientific revolution (SR) period (or stage) in the development of science. The history of scientific meteoritics birth and the corresponding alteration of the astronomical picture of the world ("the local Chladni's scientific revolution") are considered as an example of such process (that of scientific revolution development). The concept of scientific revolution was formed, first of all, precisely in astronomy, the science that has formed the very base of the world outlook (religious, at its early stages). The last circumstance explains the particularly sharpness and dramatic character of the first revolution in

  15. Low-Thrust Many-Revolution Trajectory Optimization via Differential Dynamic Programming and a Sundman Transformation

    Science.gov (United States)

    Aziz, Jonathan D.; Parker, Jeffrey S.; Scheeres, Daniel J.; Englander, Jacob A.

    2017-01-01

    Low-thrust trajectories about planetary bodies characteristically span a high count of orbital revolutions. Directing the thrust vector over many revolutions presents a challenging optimization problem for any conventional strategy. This paper demonstrates the tractability of low-thrust trajectory optimization about planetary bodies by applying a Sundman transformation to change the independent variable of the spacecraft equations of motion to the eccentric anomaly and performing the optimization with differential dynamic programming. Fuel-optimal geocentric transfers are shown in excess of 1000 revolutions while subject to Earths J2 perturbation and lunar gravity.

    2017-01-01

    The year 2015 was the International Year of Light. However, it also marked, the 20th anniversary of the first observation of Bose-Einstein condensation in atomic vapors by Eric Cornell, Carl Wieman and Wolfgang Ketterle. This discovery could be considered as one of the greatest achievements of quantum optics that has triggered an avalanche of further seminal discoveries and achievements. For this reason we devote this essay for the focus issue on ‘Quantum Optics in the International Year of Light’ to the recent revolutionary developments in quantum optics at the frontiers of all physics: atomic physics, molecular physics, condensed matter physics, high energy physics and quantum information science. We follow here the lines of the introduction to our book ‘Ultracold atoms in optical lattices: Simulating quantum many-body systems’ (Lewenstein et al 2012 Ultracold Atoms in Optical Lattices: Simulating Quantum Many-body Systems (Oxford: University Press)), and to a lesser extent the review article M Lewenstein et al (2007 Adv. Phys. 56 243). The book, however, was published in 2012, and many things has happened since then—the present essay is therefore upgraded to include the latest developments.

  17. Revolution in Detection Affairs

    Energy Technology Data Exchange (ETDEWEB)

    2013-11-02

    The detection of nuclear or radioactive materials for homeland or national security purposes is inherently difficult. This is one reason detection efforts must be seen as just one part of an overall nuclear defense strategy which includes, inter alia, material security, detection, interdiction, consequence management and recovery. Nevertheless, one could argue that there has been a revolution in detection affairs in the past several decades as the innovative application of new technology has changed the character and conduct of detection operations. This revolution will likely be most effectively reinforced in the coming decades with the networking of detectors and innovative application of anomaly detection algorithms.

  18. Numerical modelling of the stability of loaded shells of revolution containing fluid flows

    Science.gov (United States)

    Bochkarev, S. A.; Matveenko, V. P.

    2008-03-01

    A mixed finite-element algorithm is proposed to study the dynamic behavior of loaded shells of revolution containing a stationary or moving compressible fluid. The behavior of the fluid is described by potential theory, whose equations are reduced to integral form using the Galerkin method. The dynamics of the shell is analyzed with the use of the variational principle of possible displacements, which includes the linearized Bernoulli equation for calculating the hydrodynamic pressure exerted on the shell by the fluid. The solution of the problem reduces to the calculation and analysis of the eigenvalues of the coupled system of equations. As an example, the effect of hydrostatic pressure on the dynamic behavior of shells of revolution containing a moving fluid is studied under various boundary conditions.

  20. An Irish Revolution Without A Revolution

    Directory of Open Access Journals (Sweden)

    Aidan Beatty

    2016-03-01

    Full Text Available There is a conventional view among Irish historians that a revolution occurred in that country between the passing of the Third Home Rule Bill of 1912 and the end of the Civil War in 1923.  The violence of those years, the collapse in support for the Irish Parliamentary Party (IPP, the meteoric rise to power of Sinn Féin, a new sense of meritocracy, a greater sense of democracy and a widespread radicalism; all are seen as elements of a major change in Irish politics and life, a ‘Revolution.’  Drawing on Gramsci's notion of a “revolution without a revolution”, this paper seeks to understand the events in Ireland of 1912-23, not as a sudden rupture with the past but as the culmination of a much longer period of (often British-backed capitalist development in post-Famine Ireland. This paper argues that Irish nationalist politics in the decades before 1912 is better understood via categories such as class, gender, capitalism and the pervasive power of the British state.  As such, as well as pursuing a reassessment of the project of Irish historical development and state-building, this paper also seeks a reassessment of the project of (an equally statist Irish historiography.

  2. A Hierarchy of Linear Threshold Models for the Spread of Political Revolutions on Social Networks

    CERN Document Server

    Lang, John C

    2015-01-01

    We study a linear threshold agent-based model (ABM) for the spread of political revolutions on social networks using empirical network data. We propose new techniques for building a hierarchy of simplified ordinary differential equation (ODE) based models that aim to capture essential features of the ABM, including effects of the actual networks, and give insight in the parameter regime transitions of the ABM. We relate the ABM and the hierarchy of models to a population-level compartmental ODE model that we proposed previously for the spread of political revolutions [1], which is shown to be mathematically consistent with the proposed ABM and provides a way to analyze the global behaviour of the ABM. This consistency with the linear threshold ABM also provides further justification a posteriori for the compartmental model of [1]. Extending concepts from epidemiological modelling, we define a basic reproduction number $R_0$ for the linear threshold ABM and apply it to predict ABM behaviour on empirical networ...

  4. SOHO starts a revolution in the science of the Sun

    Science.gov (United States)

    1996-07-01

    In addition, SOHO has found clues to the forces that accelerate the solar wind of atomic particles blowing unceasingly through the Solar System. By relating the huge outbursts called coronal mass ejections to preceding magnetic changes in the Sun, SOHO scientists hope to predict such events which, in the Earth's vicinity, endanger power supplies and satellites. SOHO sees differences in the strength of the solar wind in various directions, by mapping a cavity in the cloud of interstellar hydrogen surrounding the Sun. As a bonus, SOHO secured remarkable images of Comet Hyakutake, by ultraviolet and visible light. The revolution in solar science will seem more complete when all the pieces and actions of the Sun, detected by twelve different instruments, are brought together in observations and concepts. Fundamental questions will then be open to re-examination, about the origin of the Sun's magnetism, the cause of its variations in the 11-year cycle of sunspot activity, and the consequences for the Solar System at large. SOHO is greater than the sum of its parts. "SOHO takes solar science by storm," says Roger Bonnet, the European Space Agency's Director of Science, "thanks to its combination of instruments. Unprecedented results from individual telescopes and spectrometers are impressive, of course, but what is breathtaking is SOHO's ability to explore the Sun all the way from its nuclear core to the Earth's vicinity and beyond. We can expect a completely new picture of how agitation inside the Sun, transmitted through the solar atmosphere, directly affects us on the Earth." SOHO is a project of international cooperation between the European Space Agency and NASA. The spacecraft was built in Europe and instrumented by scientists on both sides of the Atlantic. NASA launched SOHO and provides the ground stations and an operations centre at the Goddard Space Flight Center near Washington. SOHO has an uninterrupted view of the Sun from a halo orbit around Lagrangian

    The so-called chemical revolution has produced a vast historiographical corpus. Yet the patient's voice remains surprisingly absent from these stories. Based on the archives of the Institut de Psychiatrie (Brussels), this paper traces the introduction of Largactil as recounted in patient letters, physician records and nurse notes. The paper thus contributes to the history of therapies from below, but also participates in the historiographical debate about whether the introduction of neuroleptics can indeed be considered a revolution.

    Science.gov (United States)

    Obukhova, Elena; Zuckerman, Ezra W; Zhang, Jiayin

    2014-09-01

    The authors examine the popularity of boys' given names in Beijing before and after the onset of the Cultural Revolution to clarify how exogenous and endogenous factors interact to shape fashion. Whereas recent work in the sociology of culture emphasizes the importance of endogenous processes in explaining fashion, their analysis demonstrates two ways in which politics shaped cultural expression during the Cultural Revolution: by promoting forms of expression reflecting prevailing political ideology and by limiting individuals' willingness to act differently. As argued by Lieberson and developed further in this article, the second condition is important because endogenous fashion cycles require a critical mass of individuals who seek to differentiate themselves from common practice. Exogenous factors can influence the operation of the endogenous factors. The authors discuss the implications of their study for understanding the nature of conformity under authoritarian regimes and social conditions supporting individual expression.

  20. Complexity and the Limits of Revolution: What Will Happen to the Arab Spring?

    CERN Document Server

    Gard-Murray, Alexander S

    2012-01-01

    The recent social unrest across the Middle East and North Africa has deposed dictators who had ruled for decades. While the events have been hailed as an "Arab Spring" by those who hope that repressive autocracies will be replaced by democracies, what sort of regimes will eventually emerge from the crisis remains far from certain. Here we provide a complex systems framework, validated by historical precedent, to help answer this question. We describe the dynamics of governmental change as an evolutionary process similar to biological evolution, in which complex organizations gradually arise by replication, variation and competitive selection. Different kinds of governments, however, have differing levels of complexity. Democracies must be more systemically complex than autocracies because of their need to incorporate large numbers of people in decision-making. This difference has important implications for the relative robustness of democratic and autocratic governments after revolutions. Revolutions may disr...

  1. Population growth and economic development in the very long run: a simulation model of three revolutions.

    Science.gov (United States)

    Steinmann, G; Komlos, J

    1988-08-01

    The authors propose an economic model capable of simulating the 4 main historical stages of civilization: hunting, agricultural, industrial, and postindustrial. An output-maximizing society to respond to changes in factor endowments by switching technologies. Changes in factor proportions arise through population growth and capital accumulation. A slow rate of exogenous technical process is assumed. The model synthesizes Malthusian and Boserupian notions of the effect of population growth on per capita output. Initially the capital-diluting effect of population growth dominates. As population density increases, however, and a threshold is reached, the Boserupian effect becomes crucial, and a technological revolution occurs. The cycle is thereafter repeated. After the second economic revolution, however, the Malthusian constraint dissolves permanently, as population growth can continue without being constrained by diminishing returns to labor. By synthesizing Malthusian and Boserupian notions, the model is able to capture the salient features of economic development in the very long run.

    Full Text Available This article explores the question of the political meaning of the term “revolution” and the relation that has been established and should continue to be established between revolution and freedom. To this effect, the article examines some of the main proposals set forth in this respect by three contemporary thinkers, Hannah Arendt, Alain Badiou and Slavoj Žižek, with occasional references to Michel Foucault and Antonio Negri. The proposal argued for here is that Arendt’s notion of revolution and the notions of event and act put forth in the radical political theories of Badiou and Žižek intersect and necessarily supplement one another.

    Full Text Available This article attempts to present some reflections about Rosa Luxemburg’sworks from the first Russian revolution (1905-1906. I consider Luxemburg’sview on the historical meaning of this revolution and discuss her analyses of classstruggle in 1905-1906. The description of class struggle’s forms and its dynamicsis the most important and interesting excerpt of Luxemburg’s works from this time.She emphasized the meaning of a revolutionary sense of freedom and the changingworkers consciousness that happens during the revolution. She presents an inspiringdialectic relation between defeated rebellion or revolution and the final victory ofsocialist movement. I think that Luxemburg’s perspective may be useful for researchon contemporary social struggles (e.g. “Arab Spring”, “Occupy!” and helpful insearching for new forms of organization for radical liberation movements.

    Role-play is an interesting, although underexplored, way of teaching physics in high school. This paper presents a science-technology-society (STS) approach to the teaching of heat engines based on a role-play of the Industrial Revolution. Enacting the role-play, students are presented not only to scientific concepts, but also to the social and technological controversies of industrial development.

  6. The Arab Spring: A Simple Compartmental Model for the Dynamics of a Revolution

    Lang, John

    2012-01-01

    The self-immolation of Mohamed Bouazizi on December 17, 2011 in the small Tunisian city of Sidi Bouzid, set off a sequence of events culminating in the revolutions of the Arab Spring. It is widely believed that the Internet and social media played a critical role in the growth and success of protests that led to the downfall of the regimes in Egypt and Tunisia. However, the precise mechanisms by which these new media affected the course of events remain unclear. We introduce a simple compartmental model for the dynamics of a revolution in a dictatorial regime such as Tunisia or Egypt which takes into account the role of the Internet and social media. An elementary mathematical analysis of the model identifies four main parameter regions: stable police state, meta-stable police state, unstable police state, and failed state. We illustrate how these regions capture, at least qualitatively, a wide range of scenarios observed in the context of revolutionary movements by considering the revolutions in Tunisia and ...

    2004-01-01

    This paper focuses on 'triple helix' effects in biosciences. Scientific change can have profound socioeconomic effects. The molecular biology revolution tilted pharmaceuticals production away from its fine chemistry path dependence into microbiology and biotechnology. The key to any triple helix effects has thus shifted to universities and spinouts buttressed with burgeoning public funding, leaving 'big pharma' increasingly playing the role of licenser and marketer of bought-in therapeutic tr...

  9. Uniformly valid solutions of the coupling turning-point problem in revolution shell vibration

    Institute of Scientific and Technical Information of China (English)

    2009-01-01

    The turning-point problem in free vibration of revolution shells has the coupling property between the bending and membrane solutions. The uniformly valid solutions for this coupling turning-point problem are obtained based on three categories of generalized functions. Furthermore, they are verified to be uniformly valid in the low, turning-point and high frequency ranges. The obtained solutions exhibit a symmetric coupling structure between the bending and membrane solutions.

  10. Application of GM crops in Sub-Saharan Africa: lessons learned from Green Revolution.

    2011-01-01

    While the Green Revolution has been successful in some regions like South and East Asia, it could hardly address any achievement in Sub-Saharan Africa (SSA). This paper tries to draw a picture on lessons learned from the failures of this revolution that should be taken into account before implementing the so-called Gene Revolution in the SSA region. After scrutinizing the failures and the pros and cons of GM crops in the region, the paper introduces some potentials for improving the malnutrition situation in SSA through launching a successful GM technology. However, it remains doubtful whether this technology can improve the situation of small-scale farmers as long as they receive no financial support from their national governments. Therefore, before any intervention, the socio-economic and environmental impacts of GM technology need to be carefully addressed in the framework of a series of risk assessment studies. Besides, some sort of multi-stakeholder dialog (from small-scale farmers to consumers) involving public-private sector and non-governmental organizations should be heated up at both national and regional levels with regard to the myths and truths of this technology.

    2016-10-01

    Full Text Available In this paper, Gergely Kunt analyzes the collaborative diary writing of two preadolescent boys from the period of the Hungarian Revolution of 1956, during which they decided to act as reporters and writers to create their own chronicles of the events transpiring between October 1956 and March 1957. Twelve-year-old Gyula Csics and thirteen-year-old János Kovács were close friends and neighbors in a tenement house in Budapest, which resulted in their collaborate project of writing and illustrating their own diaries in an attempt to record the events of the Hungarian Revolution. During this collaborative project, they would read and copy each other’s diaries, which primarily focused on public events, rather than the preadolescents’ private lives. In addition to their handwritten entries, the two boys illustrated their diaries with drawings that depicted street fights or damaged buildings, as well as newspaper clippings and pamphlets, which they had collected during and after the Revolution.

  13. Toward a microbial Neolithic revolution in buildings.

    Science.gov (United States)

    Thaler, David S

    2016-03-29

    The Neolithic revolution--the transition of our species from hunter and gatherer to cultivator--began approximately 14,000 years ago and is essentially complete for macroscopic food. Humans remain largely pre-Neolithic in our relationship with microbes but starting with the gut we continue our hundred-year project of approaching the ability to assess and cultivate benign microbiomes in our bodies. Buildings are analogous to the body and it is time to ask what it means to cultivate benign microbiomes in our built environment. A critical distinction is that we have not found, or invented, niches in buildings where healthful microbial metabolism occurs and/or could be cultivated. Key events affecting the health and healthfulness of buildings such as a hurricane leading to a flood or a burst pipe occur only rarely and unpredictably. The cause may be transient but the effects can be long lasting and, e.g., for moisture damage, cumulative. Non-invasive "building tomography" could find moisture and "sentinel microbes" could record the integral of transient growth. "Seed" microbes are metabolically inert cells able to grow when conditions allow. All microbes and their residue present actinic molecules including immunological epitopes (molecular shapes). The fascinating hygiene and microbial biodiversity hypotheses propose that a healthy immune system requires exposure to a set of microbial epitopes that is rich in diversity. A particular conjecture is that measures of the richness of diversity derived from microbiome next-generation sequencing (NGS) can be mechanistically coupled to--rather than merely correlated with some measures of--human health. These hypotheses and conjectures inspire workers and funders but an alternative is also consequent to the first Neolithic revolution: That the genetic uniformity of contemporary foods may also decrease human exposure to molecular biodiversity in a heath-relevant manner. Understanding the consequences--including the unintended

    A striking coincidence of revolution periods of S-stars orbiting a supermassive black hole at the Galactic Center of the Milky Way and oscillation periods of such solar and terrestrial observables as the sunspot number, the geomagnetic field Y-component and the global temperature is established on basis of the corresponding experimental data. Rejecting randomness of this discovered coincidence, we put forward a hypothesis that modulation of dark matter flows in the Milky Way by the S-stars is responsible for such a frequency transfer from the Galactic Center to the Solar System.

  15. Mathematical simulation of a profile cutter as a surface of revolution

    Bubenchikov, A. M.; Kazakavitschyus, S. M.; Shcherbakov, N. R.

    2016-04-01

    Various types of cutters (spherical, toroidal, etc.) are used in surface processing of parts of a transmission mechanism. The cost of a special profile tool is somewhat higher than that of such cutters. But the increase in the cost of the tool is compensated by a significant reduction in the time of processing parts. The present paper deals with a mathematical model of a profile cutter surface (as a surface of revolution) for processing parts of a cylindrical transmission gear with an eccentrically cycloidal gearing (EC-gearing). A computer program for determining radii of the cutter's circular cross sections for a given set of axial displacements was created.

    This paper presents an analysis of validity of the Mellin transform when applied to small angle scattering of X-rays or neutrons by a polydisperse set of ellipsoids of revolution. It constitutes a continuation of a previous work performing the same kind of analysis for a set of diffusing particles, consisting of nearly spherical particles. In particular the analysis was focused on the accuracy associated to the size distribution, average radius, total volume of scattering particles as obtained by applying the Mellin transform to the scattering patterns.

    Trudeau, Richard J

    1986-01-01

    How unique and definitive is Euclidean geometry in describing the "real" space in which we live? Richard Trudeau confronts the fundamental question of truth and its representation through mathematical models in The Non-Euclidean Revolution. First, the author analyzes geometry in its historical and philosophical setting; second, he examines a revolution every bit as significant as the Copernican revolution in astronomy and the Darwinian revolution in biology; third, on the most speculative level, he questions the possibility of absolute knowledge of the world. Trudeau writes in a lively, entertaining, and highly accessible style. His book provides one of the most stimulating and personal presentations of a struggle with the nature of truth in mathematics and the physical world. A portion of the book won the Pólya Prize, a distinguished award from the Mathematical Association of America. "Trudeau meets the challenge of reaching a broad audience in clever ways...(The book) is a good addition to our literature o...

  19. Revolutions that made the earth

    Lenton, Tim

    2013-01-01

    The Earth that sustains us today was born out of a few remarkable, near-catastrophic revolutions, started by biological innovations and marked by global environmental consequences. The revolutions have certain features in common, such as an increase in the complexity, energy utilization, and information processing capabilities of life. This book describes these revolutions, showing the fundamental interdependence of the evolution of life and its non-living environment. We would not exist unless these upheavals had led eventually to 'successful' outcomes - meaning that after each one, at length, a new stable world emerged. The current planet-reshaping activities of our species may be the start of another great Earth system revolution, but there is no guarantee that this one will be successful. This book explains what a successful transition through it might look like, if we are wise enough to steer such a course. This book places humanity in context as part of the Earth system, using a new scientific synthe...

    2016-12-01

    Full Text Available In this paper the steady laminar flow of viscous incompressible ferromagnetic fluid is considered in a slot between fixed surfaces of revolution having a common axis of symmetry. The boundary layer ferromagnetic equations for axial symmetry are expressed in terms of the intrinsic curvilinear orthogonal coordinate system x, θ ,y.The method of perturbation is used to solve the boundary layer equations. As a result, the formulae defining such parameters of the flow as the velocity components vx, vy, and the pressure , were obtained.

  2. Thomas Kuhn's 'Structure of Scientific Revolutions' applied to exercise science paradigm shifts: example including the Central Governor Model.

    Science.gov (United States)

    Pires, Flávio de Oliveira; de Oliveira Pires, Flávio

    2013-07-01

    According to Thomas Kuhn, the scientific progress of any discipline could be distinguished by a pre-paradigm phase, a normal science phase and a revolution phase. The science advances when a scientific revolution takes place after silent period of normal science and the scientific community moves ahead to a paradigm shift. I suggest there has been a recent change of course in the direction of the exercise science. According to the 'current paradigm', exercise would be probably limited by alterations in either central command or peripheral skeletal muscles, and fatigue would be developed in a task-dependent manner. Instead, the central governor model (GCM) has proposed that all forms of exercise are centrally-regulated, the central nervous system would calculate the metabolic cost required to complete a task in order to avoid catastrophic body failure. Some have criticized the CGM and supported the traditional interpretation, but recently the scientific community appears to have begun an intellectual trajectory to accept this theory. First, the increased number of citations of articles that have supported the CGM could indicate that the community has changed the focus. Second, relevant journals have devoted special editions to promote the debate on subjects challenged by the CGM. Finally, scientists from different fields have recognized mechanisms included in the CGM to understand the exercise limits. Given the importance of the scientific community in demarcating a Kuhnian paradigm shift, I suggest that these three aspects could indicate an increased acceptance of a centrally-regulated effort model, to understand the limits of exercise.

  3. The Development of Genetics in the Light of Thomas Kuhn's Theory of Scientific Revolutions.

    2015-01-01

    The concept of a paradigm is in the key position in Thomas Kuhn's theory of scientific revolutions. A paradigm is the framework within which the results, concepts, hypotheses and theories of scientific research work are understood. According to Kuhn, a paradigm guides the working and efforts of scientists during the time period which he calls the period of normal science. Before long, however, normal science leads to unexplained matters, a situation that then leads the development of the scientific discipline in question to a paradigm shift--a scientific revolution. When a new theory is born, it has either gradually emerged as an extension of the past theory, or the old theory has become a borderline case in the new theory. In the former case, one can speak of a paradigm extension. According to the present author, the development of modern genetics has, until very recent years, been guided by a single paradigm, the Mendelian paradigm which Gregor Mendel launched 150 years ago, and under the guidance of this paradigm the development of genetics has proceeded in a normal fashion in the spirit of logical positivism. Modern discoveries in genetics have, however, created a situation which seems to be leading toward a paradigm shift. The most significant of these discoveries are the findings of adaptive mutations, the phenomenon of transgenerational epigenetic inheritance, and, above all, the present deeply critical state of the concept of the gene.

  6. Revolutions in Neuroscience: Tool Development

    Directory of Open Access Journals (Sweden)

    John eBickle

    2016-03-01

    Full Text Available Thomas Kuhn’s famous model of the components and dynamics of scientific revolutions is still dominant to this day across science, philosophy, and history. The guiding philosophical theme of this paper is that, concerning actual revolutions in neuroscience over the past sixty years, Kuhn’s account is wrong. There have been revolutions, and new ones are brewing, but they do not turn on competing paradigms, anomalies, or the like. Instead, they turn exclusively on the development of new experimental tools. I adopt a metascientific approach and examine in detail the development of two recent neuroscience revolutions: the impact of engineered genetically mutated mammals in the search for causal mechanisms of higher cognitive functions; and the more recent impact of optogenetics (and DREADDs. The two key metascientific concepts I derive from these case studies are a revolutionary new tool’s motivating problem, and its initial and second-phase hook experiments. These concepts hardly exhaust a detailed metascience of Tool Development experiments in neuroscience, but they get that project off to a useful start and distinguish the subsequent account of neuroscience revolutions clearly from Kuhn’s famous model. I close with a brief remark about the general importance of molecular biology for a current philosophical understanding of science, as comparable to the place physics occupied when Kuhn formulated his famous theory of scientific revolutions.

  7. The revolution of the biology of the genome

    2004-01-01

    Sequence data of entire eukaryotic genomes and their detailed comparison have provided new evidence on genome evolution. The major mechanisms involved in the increase of genome sizes are polyploidization and gene duplication.Subsequent gene silencing or mutations,preferentially in regulatory sequences of genes,modify the genome and permit the development of genes with new properties. Mechanisms such as lateral gene transfer,exon shuffling or the creation of new genes by transposition contribute to the evolution of a genome,but remain of relatively restricted relevance.Mechanisms to decrease genome sizes and,in particular,to remove specific DNA sequences,such as blocks of satellite DNAs,appear to involve the action of RNA interference (RNAi). RNAi mechanisms have been proven to be involved in chromatin packaging related with gene inactivation as well as in DNA excision during the macronucleus development in ciliates.

    Directory of Open Access Journals (Sweden)

    Rahul eOjha

    2015-11-01

    Full Text Available Recent changes in medical education have highlighted the importance of experiential learning. Simulation is one model that has gained significant attention in the last decade and has been widely adopted as a training and assessment tool in medical education. Paediatric simulation has been utilized to teach various skills including resuscitation and trauma management, procedural skills and team training. It is also a valuable tool for health care educators, as it allows learners to achieve competence without putting patients at risk. Recent literature demonstrates increased retention of knowledge and skills after simulation based training. Further research is required to improve current simulation curriculums, develop validated assessment tools and to demonstrate improved clinical outcomes after simulation based training. We conducted an online search of original and review articles related to simulation and paediatric medical education and provide an overview of the role and utility of simulation in paediatrics.

    1979-01-01

    It is suggested that asymptotic results for the behavior of thin shells can be incorporated in a general computer code for the analysis of a complex shell structure. The advantage when compared to existing finite difference or finite element codes is a substantial reduction in computational labor with the capability of working to a specified level of accuracy. A reduction in user preparation time and dependance on user judgment is also gained, since mesh spacing can be internally generated. The general theory is described in this paper, as well as the implementation in the computer code FAST 1 (Functional Algorithm for Shell Theory) for the analysis of the general axisymmetric shell structure with axisymmetric loading.

    Full Text Available The aim of the article. The aim of the article is to analyze factors contribute to the transformation of economic systems in conditions of the Third industrial revolution. The result of the analysis. The definition of the third industrial revolution (T. i. r. as the multidimensional complex phenomenon is given. Its key features are characterized. They are: the transition to renewable energy sources and raw materials, mass introduction of additive technologies and network manufacturing systems, digital base of fixing and transmission of information, the formation of the horizontal production and consumption patterns, solidary forms of economic relations. The reality of perspectives of renewable energy sources introduction are confirmed with the facts of their development dynamics. Since 2000, the volume of alternative power has doubled: on the sun 7 times, and on the wind 4 times. Under each doubling of energy production its costs is reduced on the sun by 24%, and on the wind 17%. It is shown the functional possibilities of additive technologies: unlimited design versions; free provision of complexity; free provision of variability, minimal waste; production for individual demand; exclusion assembly step; direct materialization of information. Basic groups of the T. i. r. innovations in energy, raw material, technological, organizational and economic sections are characterized. Conclusions. The Third industrial revolution allows to transit to renewable resources and additive technologies. It creates the foundation for a significant reduction in specific resource consumption for conventional unit of human vital functions. The conditions for horizontal production-consumption structures and solidary forms of economic relations are created as well.

    2006-09-01

    The industrialization and urbanization of Britain during the 19th century gave the medical profession something to think about. In particular, were the radical changes taking place in society responsible for the sudden rise in endemic and epidemic disease? This article (part of the Science in the Industrial Revolution series) examines the reactions of two key figures in the history of British public health, James Philips Kay and Thomas Southwood Smith, to this question. Their outlooks typify the tendency of Victorian medical practitioners to construct economies of health that saw disease as a consequence of the violation of natural laws and cycles rather than as a product of industrial modernity.

    Ryan, C.J.

    1977-07-07

    The purpose of this paper is to provide a context for choosing the energy system that will replace fossil fuels. As fossil fuels, the energy source of industrialization, are depleted, the world enters into the third most important energy and social revolution in the development of civilization. Natural and social systems operate under the same principles of energy management. Growth, stability, or decline is determined by the interdependent relationship between energy and structure (Energy in Natural and Social Systems). The evolution of civilization over more than a million years can be seen as a successful quest to control greater amounts of energy through social organization in three different energy and social systems: hunting and gathering, agriculture, and fossil fuels (Two Energy and Social Revolutions). Many nations based on different energy and social structures have flourished and disappeared throughout history. The cases of Egypt, Rome, and Britain are used to illustrate the dynamic forces that affect the rise and fall of empires, dependence on foreign resources, and the changing purposes of social organization (The Influence of Energy on Nations). The energy perspective of the paper suggests the relationship between continuous growth and social discontinuity in U.S. history (Continuous Growth and Social Discontinuity in the U.S.). The physical and social consequences of future energy alternatives are discussed in terms of an Orwellian, Jeffersonian, and Malthusian type future (The Third Revolution: Orwell, Jefferson, or Malthus). The paper concludes with an endorsement of solar energy as the alternative most likely to afford a stable future in a humanly organized environment.

    Full Text Available Metaphor is persuasive in having cognitive, emotional and aesthetic effect. It has been argued that any visual representation can be considered a metaphor if it represents a metaphoric thought. Chartris-Black’s Critical Metaphor Analysis and Forceville’s model of pictorial metaphor are both used to analyze the data under investigation. Chateris-Black’s Critical Metaphor Analysis is used based on the idea that the use of metaphors helps in conveying the underlying ideologies of the writers. Moreover, Forceville’s model of pictorial metaphor aims at investigating various types of pictorial metaphor in different genres. The political cartoons investigated in this study are drawn from three independent newspapers: Al Dastour, Al Masry Al Youm and Al Youm AL Sabea during the 25th of January 2011 Egyptian Revolution. This study aims at exploring how metaphors are expressed in the visual mode, more specifically in newspapers cartoons, tracing the use of pictorial metaphor in selected independent newspapers cartoons during the eighteen days of the 25th of January 2011 Egyptian revolution, and finally, identifying the cartoonists’ underlying ideological motivations and their attitudes to the revolution, which ultimately direct the audience’s ideology. The results of this study suggest that Chateris-Black’s Critical Metaphor Analysis can be applied not only on the textual level, but also on the semiotic and pictorial ones. In addition, metaphors are frequently used in political cartoons to evoke strong emotive effect and reinforce ideologies to achieve persuasion.

    TERC’s EarthLabs project provides rigorous and engaging Earth and environmental science labs. Four existing modules illustrate sequences for learning science concepts through data analysis activities and hands-on experiments. A fifth module, developed with NSF, comprises a series of linked inquiry based activities focused on the cryosphere to help students understand concepts around change over time on multiple and embedded time scales. Teachers recruited from the NSF-OEDG-sponsored Texas Earth and Space Science (TXESS) Revolution teacher professional development program conducted a pedagogical review of the Cryosphere EarthLabs module and provided feedback on how well the materials matched high school needs in Texas and were aligned with state and national standards. Five TXESS Revolution teachers field tested the materials in their classrooms and then trained other TXESS Revolution teachers on their implementation during spring and summer 2010. Here we report on the results of PD delivery during the summer 2010 TXESS Revolution summer institute as determined by (1) a set of evaluation instruments that included a pre-post concept map activity to assess changes in workshop teachers’ understanding of the concepts presented, a pre-post test content knowledge test, and a pre-post survey of teachers’ comfort in teaching the Texas Earth and Space Science standards addressed by the module; (2) teacher reflections; and (3) focus group responses. The findings reveal that the teachers liked the module activities and felt they could use them to teach Environmental and Earth Science. They appreciated that the sequence of activities contributed to a deeper understanding and observed that the variety of methods used to present the information accommodates different learning styles. Information about the cryosphere was new to all the teachers. The content knowledge tests reveal that although teachers made appreciable gains, their understanding of cryosphere, how it changes

The first one is the global Price Revolution; the second is the wars between Ottoman and Iran. The silk industry in Bursa which was the most important silk center of Ottoman had been affected negatively from these events. The non-tariff barriers had been created by the Iran wars also weakened the relations borne from the silk trade among these two countries. The diminished trade volume decreased the tax revenues; consequently both countries had been affected unfavorably.

    Proposed in this paper is a kinetostatic performance index for the optimum dimensioning of planar manipulators of the serial type. The index is based on the concept of distance of the underlying Jacobian matrix to a given isotropic matrix that is used as a reference model for purposes of performance evaluation. Applications of the index fall in the realm of design, but control applications are outlined. The paper focuses on planar manipulators, the basic concepts being currently extended to their three-dimensional counterparts.

    2006-01-01

    The recent publication of the human genomic sequence is the most important progress in biology. It originates from four major watersheds between 1860-1865, namely the biological evolution by Darwin in 1858, the Mendel laws of heredity in 1865, the basis of physiology established by Claude Bernard also in 1865, and the discoveries of microbacteria by Louis Pasteur around 1857. Before 1860, biology did not exist as a science. After 1860, the Darwin's theory progressively became a law after the discovery of the DNA polymorphism and that of the mechanisms of genetic mixing. So far the Mendel's laws were confirmed in parallel with the development of molecular genetics after the discovery of DNA structure and genetic code. The discovery of hormones is one example, amongst several on how integrative physiology applies to Claude Bernard's basis. Finally, based on Pasteur's discovery and Pasteur Institutes, microbiology became a tool for molecular biologists.

    2014-01-01

    There is no question about the negative effects of child sexual abuse. Freud's seduction theory asserts that psychoneuroses in adults are caused by reactivation of forgotten recollections of gross sexual abuse (involving the genitals) that had taken place prior to the age of 8 to 10 years. His contribution consisted in the discovery of specific events, prior to puberty, which were indispensable to the formation of psychoneuroses. If an adult patient recalled an infantile sexual experience, Freud assumed the interference of a pervert: a child was sexually innocent unless it had been traumatized. But Freud's technique of clinical exploration had not attained adequate reliability and was not immune to prejudices. Freud himself dropped his mechanical, static theory that presupposed a single type of accidentally occurring trauma prior to puberty, allowing him to develop his new drive and fantasy theory.

    Advances in biotechnology have brought gene therapy to the forefront of medical research. The prelude to successful gene therapy i.e. the efficient transfer and expression of a variety of human gene into target cells has already been accomplished in several systems. Safe methods have been devised to do this, using several viral and no-viral vectors. Two main approaches emerged: in vivo modification and ex vivo modification. Retrovirus, adenovirus, adeno-associated virus are suitable for gene therapeutic approaches which are based on permanent expression of the therapeutic gene. Non-viral vectors are far less efficient than viral vectors, but they have advantages due to their low immunogenicity and their large capacity for therapeutic DNA. To improve the function of non-viral vectors, the addition of viral functions such as receptor mediated uptake and nuclear translocation of DNA may finally lead to the development of an artificial virus. Gene transfer protocols have been approved for human use in inherited diseases, cancers and acquired disorders. In 1990, the first successful clinical trial of gene therapy was initiated for adenosine deaminase deficiency. Since then, the number of clinical protocols initiated worldwide has increased exponentially. Although preliminary results of these trials are somewhat disappointing, but human gene therapy dreams of treating diseases by replacing or supplementing the product of defective or introducing novel therapeutic genes. So definitely human gene therapy is an effective addition to the arsenal of approaches to many human therapies in the 21st century.

    Full Text Available This article offers some personal reflections on the difficulty of teaching the behaviorist perspective in the psychology classroom. The problems focus on the inadequacy of introductory textbooks—which mischaracterize behaviorism, only present the most extreme behaviorist positions, make no mention of the neobehaviorist perspective, fail to discuss that there is no accepted criteria for determining what type of behavior is cognitive, and provide a definition of cognition that is, not only inconsistent across texts, but so broad as to overshadow the behaviorist contributions. Suggestions are provided for instructors on how to present to their students an accurate portrayal of behaviorism.

    Francesca Borruso

    2015-01-01

    Full Text Available The essay analyzes how the parent-children relationship changed within the bourgeois family between the Eighteen and the Nineteen centuries, also with a look to gender differences. The birth of the love marriage, the transformation of the parent-child relationship towards a more intimate and equal affective relationship, the transformation of the education style, the nineteenth-century cult of motherhood are some of the topics analyzed, that are deemed essential for understanding the complex transformations of family relationships in the western society. Jean-Jacques Rousseau is one of the first representatives of these changes of mentality. The radical critique of the family initiated by Rousseau, in fact, opens the way to a slow shift towards a democratic conception of the relationship between parents and children. The new model of family proposed by Rousseau – notwithstanding the male superiority in terms of «natural law» – is grounded on the agreement and mutual support between the spouses. Finally, the analysis of certain family stories – Manzoni and Rosselli – offers a micro-historical glance to family relationships during the Nineteenth and Twentieth centuries. The sources relate not only to the educational literature but also to novels on education, i.e. those non-official narratives (diaries, epistolaries, literary sources that can explain the educational experiences and the network of social and educational conditionings individual lives Cómo referenciar este artículo / How to reference this article Borruso, F.

    Chromatin remodellers are specialized multi-protein machines that enable access to nucleosomal DNA by altering the structure, composition and positioning of nucleosomes. All remodellers have a catalytic ATPase subunit that is similar to known DNA-translocating motor proteins, suggesting DNA translocation as a unifying aspect of their mechanism. Here, we explore the diversity and specialization of chromatin remodellers, discuss how nucleosome modifications regulate remodeller activity and consider a model for the exposure of nucleosomal DNA that involves the use of directional DNA translocation to pump 'DNA waves' around the nucleosome.

    In humans, the erect position and bipedal walk is possible because of a balance between pelvic and spinal parameters. The most important pelvic parameter is the pelvic incidence which represents the base on which the spine lies. With aging, thoracic kyphosis increases, lumbar lordosis decreases, compromising the spino-pelvic balance. Compensatory phenomenons are possible, but rely mostly on the amplitude of pelvic incidence. Analysis of spino-pelvic parameters and detection of a compensated or uncompensated sagittal imbalance are mandatory before any therapeutic action is undertaken for a degenerative pathology of the spine.

  3. Understanding of Arab Spring with Chaos Theory - Uprising or Revolution

    Science.gov (United States)

    Açıkalın, Şuay Nilhan; Bölücek, Cemal Alpgiray

    `Arab Spring' can be considered as one of the most remarkable events in the history of world politics. On December 18, 2010, a Tunisian young protestor burned himself in a public square of the city. This event triggered probably one of the most chaotic and long term uprisings in the Middle East. From the day of its initiation until the present, `Arab Spring' in the Middle East created unstable political situation and several uprisings. In this chapter, we will first give general information about chaos theory, and then we will examine the `butterfly effect' created by the Tunisian young protestor and process of Arab Spring in the Middle East regarding its extend and form in those countries within the framework of chaos theory. For the first part of this chapter, the spark created by the Tunisian young protestor and its effects can be analyzed under `butterfly effect' perspective within chaos theory, arguing whether the events followed each other consecutively or randomly. The question is whether the incidents following each other have reasonable links of causality to one another, or the events defining the phenomena known as `Arab Spring' have no predictable reasons and outcomes regardless of the regional, social and political differences. The events caused the collapse of the regimes in Tunisia, Egypt and Libya; they had very serious outcomes.

    2011-01-01

    The foundations of proteomics are to study gene products and their regulatory roles within cells. Paradoxically, the only evidence that sperm cells make new proteins is through mitochondrial protein synthesis. Yet despite this, spermatozoa are the perfect candidates for mass spectrometry and hence, proteomic analysis. These enterprising cells use a plethora of post-translational modifications in order to gain functionality following their production within the testis. By using a combination of two-dimensional polyacrylamide gel electrophoresis (2D-PAGE), and more recently liquid chromatography-mass spectrometry (LC-MS)/MS, recent advances in sperm cell biology, through the use of proteomics, is making unparalleled progress. The protein inventory lists being generated have shed light on transmembrane proteins, kinases and chaperones never previously recognized. In addition, the ability to isolate either phosphopeptides or glycopeptides and quantify the differences between cells of two different populations make proteomic analysis of spermatozoa a real chance to finally answer some age old questions.

    Full Text Available The interest towards student demonstrations has increased recently in connection with the recognized and highly active role of youth in the revolution of the late XX – early XXI century. Here a question arises: What was the role of the students in the process of destabilization of Russian society before the First Russian Revolution? The article is devoted to student unrest in St. Petersburg in the autumn of 1904. It is shown that spontaneous student movement was at the heart of unrest – as well as in 1899–1902. «Liberation Union» has proclaimed the necessity of organizing of students and liberal professors for purposeful struggle against the autocracy – but in the events of the autumn of 1904 we cannot find the traces of activity of such organization. There was a liberal campaign, but it had a latent, disguised character, appearing in explicit and implicit criticism of the current regime. However, the agitation has created excited mood among students, and students, who were the members of a party, informed the St. Petersburg Committee of the Russian Social Democratic Labour Party about these facts. The Committee decided to use the spontaneous movement, in order to express the proletarian requirements with the help «of all-public demonstrations»; the requirements of proletariat differed from the requirements of the liberal members of Zemstvo (elective district and provincial administrative assembly in prerevolutionary Russia.

    The development and dissemination of sawah rice eco-technology in Nigeria and Ghana as prerequisites for the actualization of green revolution in West Africa were described. It showed that the neglect of the eco-technology and the overemphasis of the biotechnology have rendered the ineffective transferability of the green revolution process from Asia to Africa. The sawah eco-technology increases yield up to 5 t/hm2 through bunding and the use of inlet and outlet connecting irrigation and drainage, which enhances effective water control and management, improves the efficiency of fertilizer, improves nitrogen fixation by soil microbes and algae, increases the use of wetlands, improves soil organic matter accumulation, suppresses weed growth, and enhances immune mechanism of rice through nutrient supply. The current experience has therefore established that the technology overcomes the constraints that have limited the realization of green revolution in West Africa.

    Science.gov (United States)

    Mylopoulos, John

    Conceptual Modeling was a marginal research topic at the very fringes of Computer Science in the 60s and 70s, when the discipline was dominated by topics focusing on programs, systems and hardware architectures. Over the years, however, the field has moved to centre stage and has come to claim a central role both in Computer Science research and practice in diverse areas, such as Software Engineering, Databases, Information Systems, the Semantic Web, Business Process Management, Service-Oriented Computing, Multi-Agent Systems, Knowledge Management, and more. The transformation was greatly aided by the adoption of standards in modeling languages (e.g., UML), and model-based methodologies (e.g., Model-Driven Architectures) by the Object Management Group (OMG) and other standards organizations. We briefly review the history of the field over the past 40 years, focusing on the evolution of key ideas. We then note some open challenges and report on-going research, covering topics such as the representation of variability in conceptual models, capturing model intentions, and models of laws.

    Full Text Available This article analyzes the news reports written by the Portuguese novelist and journalist Eça de Queirós about the crisis in 1881-1882 that resulted in the bombing of Alexandria, Egypt, by a British fleet. First, following Barbie Zelizer, we examine the communication of this historical event by analyzing how the news reports covering the event were written, taking into account the literary form commonly used during the period. For Zelizer, figures could not be trusted, and the plot and storyline were preferable. Second, as proposed by Hallin and Mancini, we analyze media practices during the period and compare the practices of the British and Luso-Brazilian print media. Eça appropriated information broadcasts by British journalists and reformulated them for his readers, emphasizing the key issues that lurked beneath the events of 1881-1882. Third, we analyze how the Egyptian army and Colonel Arabi went from being demonized to a position of heroes in modern Egypt through reports by the Brazilian periodical Gazeta de Noticias that were published in 1882 in Rio de Janeiro and were considered the culmination of its journalistic activities.

    Full Text Available Jewish observance of shmita (alternatively spelled shemitah—the sabbatical year, or seventh (sheviit year—is changing. Historically rooted in agriculture, modern Jewish environmentalists are seizing upon the long-ignored environmental and social justice (tikkun olam aspects of shmita as originally described in the five books of Moses, the Torah in the Hebrew Bible, the basis of Jewish law. Primary research was conducted through key-stakeholder interviews with leading American and Israeli Jewish environmentalists and thought leaders. They see shmita as a core Jewish value—one that, like Shabbat, the Jewish sabbath, has the power to transform society.

  17. Biological Computation as the Revolution of Complex Engineered Systems

    CERN Document Server

    Gómez-Cruz, Nelson Alfonso

    2011-01-01

    Provided that there is no theoretical frame for complex engineered systems (CES) as yet, this paper claims that bio-inspired engineering can help provide such a frame. Within CES bio-inspired systems play a key role. The disclosure from bio-inspired systems and biological computation has not been sufficiently worked out, however. Biological computation is to be taken as the processing of information by living systems that is carried out in polynomial time, i.e., efficiently; such processing however is grasped by current science and research as an intractable problem (for instance, the protein folding problem). A remark is needed here: P versus NP problems should be well defined and delimited but biological computation problems are not. The shift from conventional engineering to bio-inspired engineering needs bring the subject (or problem) of computability to a new level. Within the frame of computation, so far, the prevailing paradigm is still the Turing-Church thesis. In other words, conventional engineering...

    Full Text Available The French Revolution was the occasion for the reformulation of the definitions of basic concepts as liberté, égalité, fraternité, nation, patrie, etc. At the same time a lexical creativity, a large quantity of words appeared, some of them total news or with new significations, temporary or persistants (aristocruche, humanicide, enragés, loyaume, etc..This paper examines aspects of lexical and semantic developments in Greek language focussing on the era of the French Revolution. This important period was characterized  by intensified contacts with Western Europe. In this process, Greek intellectuals expressed an open admiration of the new French model of the nation in their political works and attempted to form a new political language. Most of the modern notions were introduced from the French language, which in his turn had acquired a large amount of greek-latin loan words. The intercultural dimension provide the tools for analysing the ways in which the new terms and concepts were transfered to the greek vocabulary. These processes are examined as reflected in the Hellenic Nomarchy (Italy 1806, a crucial text of the period.

    The Egyptian Revolution 2011 has shaken the Arab world and stirred up Middle-East politics. Moreover, it caused a rush in political science and the neighboring disciplines, which had not predicted an event like this and now have troubles explaining it. While many things can be learned from the popular uprising, and from the limitations of previous scholarship, our focus will be on a moral resource, which has occasionally been noticed, but not sufficiently explored: the role of humor in keeping up the spirit of the Revolution. For 18 days, protestors persevered at Liberation Square in Central Cairo, the epicenter of resistance; at times a few dozens, at times hundreds of thousands. What they did was to fight the terror of the regime, which reached absurd peaks during those days, with humor-successfully. We offer a social-functionalist account of the uprising, which includes behavioral as well as cultural levels of analysis, and illuminates how humorous means helped to achieve deadly serious goals. By reconstructing how Egyptians laughed themselves into democracy, we outline a social psychology of resistance, which uses humor both as a sword and a shield.

    A variety of disorders have been associated with the concept of body schema. However, this concept has been interpreted in many ways, and there is no consensus on the nature and cognitive mechanisms of body schema. Historically, two major issues have been discussed. One was the body-specificity of the body schema, and the other was the relationship between input and output modality. Autotopagnosia, an inability to localize and orient different parts of the body, has been a focus of attention because it is thought to provide insight into the function of body schema. Although there have not been many cases of pure autotopagnosia, a double dissociation indicating the independence of body-specific system. There are a few working hypotheses for cognitive models of body schema, which can explain the different types of autotopagnosia. One model includes multiple representation subsystems for body processing, while another assumes the use of intrinsic and extrinsic egocentric coordinates to maintain on-line processing for body state. The consistency of these accounts should be examined in light of extensive neuroimaging and psychological data, to construct a plausible model for body schema.

    2010-01-01

    In a rotationally symmetric space $\\oM$ around an axis A (whose precise definition includes all real space forms), we consider a domain $G$ limited by two equidistant hypersurfaces orthogonal to A. Let $M \\subset \\oM$ be a revolution hypersurface generated by a graph over A, with boundary in $\\partial G$ and orthogonal to it. We study the evolution $M_t$ of $M$ under the volume-preserving mean curvature flow requiring that the boundary of $M_t$ rests on $\\partial G$ and keeps orthogonal to it. We prove that: a) the generating curve of $M_t$ remains a graph; b) the flow exists while $M_t$ does not touch the axis of rotation; c) under a suitable hypothesis relating the enclosed volume and the area of $M$, the flow is defined for every $t\\in [0,\\infty[$ and a sequence of hypersurfaces $M_{t_n}$ converges to a revolution hypersurface of constant mean curvature. Some key points are: i) the results are true even for ambient spaces with positive curvature, ii) the averaged mean curvature does not need to be positive...

    Full Text Available The article considers the problem of increasing the technological competitiveness of Ukrainian enterprises under conditions of a new industrial revolution through the development and introduction of advanced converged technologies. The classification of industrial revolutions, namely, industrial, technological, information and Industry 4.0, is presented, and it has been determined that the key factor of the latter is cyber physical systems for introduction of the client-oriented “Internet of Things”. It has been justified that the formation of Industry 4.0 in developed countries will occur through advanced production technologies (APT, which main characteristics are technological substitution, automation, customization, localization and economic efficiency. It has been found that in 2020 the main priority APT will be: systems of production process control; multidimensional modeling of complex products; intelligent production systems and robotics; systems of creation and transformation (growing of material objects and 3D-printing; materials effective in creating perspective actuating devices (compositional and those that exhibit their properties in small-size structures. It has been proved that the recovery of Ukraine’s industry is not possible on the old industrial base, and the creation of a new industry based on APT of Industry 4.0 is possible in the following areas: ICT (primarily in the field of software development; new composite materials with specified properties; industrial nanobiotechnologies (biomedicine and pharmacy, new agricultural technologies; mathematical modeling for creation of intelligent production systems; space research and development (in particular, development of the first stages of heavy missiles. The necessity of elaborating state programs of competitiveness development on the basis of APT, foresight research oftechnology priorities, promoting high-tech exports in Ukraine has been substantiated.

  7. Optimization of multi-revolution low-thrust transfer based on modified direct method

    2008-01-01

    A modified direct optimization method is proposed to solve the optimal muhi-revolution transfer with low-thrust between Earth-orbits. First, through parametefizing the control steering angles by costate variables, the search space of free parameters has been decreased. Then, in order to obtain the global optimal solution ef-fectively and robustly, the simulated annealing and penalty function strategies were used to handle the con-straints, and a GA/SQP hybrid optimization algorithm was utilized to solve the parameter optimization problem, in which, a feasible suboptimal solution obtained by GA was submitted as an initial parameter set to SQP for re-finement. Comparing to the classical direct method, this novel method has fewer free parameters, needs not ini-tial guesses, and has higher computation precision. An optimal-fuel transfer problem from LEO to GEO was taken as an example to validate the proposed approach. The results of simulation indicate that our approach is a-vailable to solve the problem of optimal multi-revolution transfer between Earth-orbits.

    Full Text Available Initiated at the very beginning of the movements, discussions about the origin and causes of the English revolution have become one of the most valuable themes within the Anglo-Saxon historiography. On the contrary, continental contemporary readings of those events remain to be decoded and fully comprehended. This article reveals and examines some of those readings, notably those registered in Italian republics and in Spain, including some of them which have remained so far out of the scope of the historian. Despite the common features apprehended among the cases studied, all of them show a wide range of interpretations; variety which derives from the different forms of approaching to the past, from the degree of pragmatism of the reports analysed, and from the ideological and cultural positioning of their authors.

    Full Text Available Color revolution is one of the new ways of changing a regime at the beginning of the twenty-first century, which has usually been carried out on corrupt, political systems remaining from the Cold War era in Eastern European countries and countries that have become independent from the former Soviet Union and through such revolution a new peaceful form of political power transition emerged. An exploration of the circumstances of Ukraine’s Orange Revolution suggests foreigners’ support and leading. Ukraine’s presidential elections of 2004 and the competition between Viktor Yushchenko and Victor Yanukovich and the presence of international observers in the process of elections and the controversy of electoral fraud and the West’s support of Yushchenko were all directed toward the formation of a color revolution in Ukraine. Poor economic conditions and official corruption, religious, linguistic, class and racial gaps in Ukraine led the way for foreigners to use them in creating electoral situations and prepare the fall of the government. The main purpose question in this article is the Orange Revolution and its causes.

  10. Sacralising Bodies

    Kaur, Ravinder

    2010-01-01

    In post-revolution Iran, the sacred notion of martyrdom has been transformed into a routine act of government – a moral sign of order and state sovereignty. Moving beyond the debates of the secularisation of the sacred and the making sacred of the secular, this article argues that the moment...... of sacralisation is realised through co-production within a social setting when the object of sacralisation is recognised as such by others. In contemporary Iran, however, the moment of sacralising bodies by the state is also the moment of its own subversion as the political-theological field of martyrdom......-sacrifice became central to the mass mobilisation against the monarchy. Once the revolutionary government came into existence, this sacred tradition was regulated to create ‘martyrs’ as a fixed category, in order to consolidate the legacy of the revolution. In this political theatre, the dead body is a site...

  15. Prediction of acoustic radiation from functionally graded shells of revolution in light and heavy fluids

    Qu, Yegao; Meng, Guang

    2016-08-01

    This paper presents a semi-analytical method for the vibro-acoustic analysis of a functionally graded shell of revolution immersed in an infinite light or heavy fluid. The structural model of the shell is formulated on the basis of a modified variational method combined with a multi-segment technique, whereas a spectral Kirchhoff-Helmholtz integral formulation is employed to model the exterior fluid field. The material properties of the shell are estimated by using the Voigt's rule of mixture and the Mori-Tanaka's homogenization scheme. Displacement and sound pressure variables of each segment are expanded in the form of a mixed series using Fourier series and Chebyshev orthogonal polynomials. A set of collocation nodes distributed over the roots of Chebyshev polynomials are employed to establish the algebraic system of the acoustic integral equations, and the non-uniqueness solution is eliminated using a combined Helmholtz integral equation formulation. Loosely and strongly coupled schemes are implemented for the structure-acoustic interaction problem of a functionally graded shell immersed in a light and heavy fluid, respectively. The present method provides a flexible way to account for the individual contributions of circumferential wave modes to the vibration and acoustic responses of functionally graded shells of revolution in an analytical manner. Numerical tests are presented for sound radiation problems of spherical, cylindrical, conical and coupled shells. The individual contributions of the circumferential modes to the radiated sound pressure and sound power of functionally graded shells are observed. Effects of the material profile on the sound radiation of the shells are also investigated.

    A method is developed to predict the buckling characteristics of an orthotropic shell of revolution of arbitrary meridian subjected to a normal pressure. The solution is given within the context of the linearized Sanders-Budiansky shell buckling theory and makes use of the differential quadrature method. Numerical results for buckling pressures and mode shapes are given for complete toroidal shells. Both completely free shells and shells with circumferential line restraints are covered. The loadings considered consist either of uniform pressure or circumferential bands of constant pressure. It is demonstrated that the differential quadrature method is numerically stable and converges. For isotropic toroidal shells, good agreement is observed with previously published analytical and finite element results. New results for buckling pressures and mode numbers are given for orthotropic shells and for band loaded shells.

    If we define scientific revolutions as changes of scientists' ontologies, types of causal explanation, and paradigmatic types of methods and instruments, Antoine-Laurent Lavoisier's contribution to chemistry did not amount to a scientific revolution. Contrary to the received view that Lavoisier initiated a "chemical revolution," which is accepted by Chang and Kusch, I argue that Lavoisier shared with the phlogistonists their "flat ontology" of chemical substance, established decades before the 1770s, their types of explaining chemical transformation, and their quantitative methods. Based on my historical reconstruction, I criticize Chang's argument that the late eighteenth-century phlogistic systems and Lavoisier's system belonged to two different theoretical traditions. As a consequence, I also question Chang's argument that the acceptance of Lavoisier's system can be explained in terms of dominance of "compositionism" over "principlism."

    Full Text Available This article aims to discuss the notion of civil society, hegemony and passive revolution in the thoughts of Antonio Gramsci and its relation to the need for implementation of environmental justice. The concept of civil society in Gramsci's view appears as a group of organisms commonly designated as “private”, formed by the organizations responsible for drafting much as the dissemination of ideologies, so understanding the school system, the churches, trade unions, political parties, professional organizations, material culture of the organization, while the concept of hegemony arises within the Marxist tradition as a response to new social settings. Despite its origins in the Russian social democracy and to be present at the thought of Lenin, this concept was developed in a more elaborated by Gramsci. The concept of “passive revolution”, “revolution–restoration” or “evolutionism” is crucial category that Gramsci uses to understand the formation of the modern bourgeois state in Italy (starting from the facts of the Risorgiment o, which culminated in the national unification, to define the fundamental features of the passage of Italian capitalism to step monopoly capitalism and to point fascism as a form of “passive revolution”. It is from this understanding that we use the concept of “passive revolution” to discuss pratics the principles of environmental justice, given that this concept applies to many episodes of the story, as well as more generally, the transition from the industrial model capitalist development of the capitalist system of sustainable development. It consists in a literature review from the work of Gramsci, where it can be concluded that the movements that call for environmental justice in Brazil and the world, mitigated by civil society through a process of passive revolution, based on the insertion of dignity human and the environment as key goals of the state, propose a new model of sustainable

    2009-01-01

    Louis Pasteur (1822-1895) is considered the most notable medical scientist of his time and perhaps one of the most distinguished of all times in the history of medicine. From Dole in France to Paris, from a student of crystals to "living ferments," and from chemistry to biology and medicine, Pasteur changed the world for the benefit of humanity. The genius of Pasteur dealt with the most pressing issues of his time, basing the germ theory on the effects that microorganisms had on fermentation and putrefaction of organic matter, which gave birth to the science of bacteriology. Many other difficult problems in medicine and biology were tackled by Pasteur, culminating in the spectacular results seen with the treatment of rabies. Surgery was no exception to the scientific conquests of Pasteur. The transformation of the surgical world arose from the antiseptic concepts of Lister that were based on the germ theory of the disease, which had been derived from the germ theory of fermentation and putrefaction discovered by Pasteur.

    Full Text Available This article sets out from an analysis of the pioneering work of Susan Buck-Morss to rethink, not only Hegel and Haiti, but broader questions surrounding dialectics and the universal brought to light by the Haitian Revolution. Reading through the lens of C.L.R. James’ The Black Jacobins, I seek to correct a series of ironic silences in her account, re-centering the importance of Toussaint’s successor, Jean-Jacques Dessalines, and underlining the dialectical importance of identitarian struggles in forging the universal. Finally, I offer Frantz Fanon’s reformulation of the Hegelian master-slave dialectic—overlooked in Buck-Morss’ account—as a corrective that allows us to truly rethink progress toward the universal in decolonized dialectical terms.

    Full Text Available This article maps the legal developments that led to the adoption of the Civil Union Act, which extended full marriage rights to same-sex couples in South Africa. It points out that this extension of marriage to same-sex couples would not have been possible if it was not for the groundbreaking decisions on sexual orientation discrimination handed down by the South African Constitutional Court over the past ten years. It al so describes the complex legal regime now in place which allows different sex couples to enter into marriage in terms of a traditional Marriage Act or the new Civil Union Act but restricts same-sex couples to entering into marriage in terms of the latter Act. The article concludes that while this extension of marriage rights can be viewed as a legal revolution, some problems remain with the legal regulation of same-sex relationships in South Africa.

    Previous analyses of relations, divergence times, and diversification patterns among extant mammalian families have relied on supertree methods and local molecular clocks. We constructed a molecular supermatrix for mammalian families and analyzed these data with likelihood-based methods and relaxed molecular clocks. Phylogenetic analyses resulted in a robust phylogeny with better resolution than phylogenies from supertree methods. Relaxed clock analyses support the long-fuse model of diversification and highlight the importance of including multiple fossil calibrations that are spread across the tree. Molecular time trees and diversification analyses suggest important roles for the Cretaceous Terrestrial Revolution and Cretaceous-Paleogene (KPg) mass extinction in opening up ecospace that promoted interordinal and intraordinal diversification, respectively. By contrast, diversification analyses provide no support for the hypothesis concerning the delayed rise of present-day mammals during the Eocene Period.

    Science.gov (United States)

    Harken, A H

    1976-11-01

    In this bicentennial year, it seems appropriate that each discipline examine its heritage. Two centuries ago, Joseph Priestley isolated "dephlogisticated air." International diplomacy surrounding the American and early French Revolutions provided an opportunity for Benjamin Franklin and Antoine Lavoisier to witness Priestley's work. The combined efforts of these analytical minds converted an illogical phlogiston myth into a practical and therapeutic principle. Lavoisier subsequently coined the word "oxy-gène." In the ensuing centuries, this substance has gained a central role in rational surgical therapy. The interaction between these scientists, their ultimate fate and their relationship to their communities appear to provide lessons relevant to present day biomedical research funding and the peer review process. The surgical community can be justifiably proud of its past. By reflecting on these events, we may perhaps concentrate the benefits without condemning ourselves to the repetition of previous error.

    "Young people were sent to the countryside during the Cultural Revolution and were later allowed to return home in the 1970s. This paper examines the return migration of Chinese youth from the countryside based on officially sanctioned reasons and grounds. The most often used reasons or grounds were in fact claims to urban residentship arising from connections to the city by previous residence, by birth and by family. Claimants negotiated with the state in a cultural language which rationalizes the claimed needs in terms of traditional social codes. The study reveals that the passive and submissive image the Chinese civil society outwardly present is deceptive. Their claims, however, still fall short of modern social citizenship."

    It is an oft-heard complaint that the UK generates some of the best science in the world, but does not reap the full reward. Hard data to verify this are difficult to come by, but at a recent talk in Oxford1, Lord Robert May, president of the Royal Society and former chief scientific advisor to the UK government, tried to quantify the issue. The number of scientific papers published annually is more or less equally divided between the US, Europe, and the rest of the world2. In the league table of publications per capita3, Table 1, European countries do extremely well, pushing the US into 11th place. May also pointed out that the US government spends 0.82% of its gross domestic product (GDP on research, while the EU spends 0.76%. Putting this in context, Japan allocates just 0.64% of GDP and the only countries that budget a higher proportion of GDP than the US are France and Finland4. The UK budgets just under 0.70% of GDP but, taking the somewhat ruthless gauge of cost per paper, comes out top. While these are, perhaps, crude measures, the figures confirm the view that scientific research in Europe is extremely competitive.

    Global population will increase by almost 1 billion people in the 1990s, the largest 10-year increase ever recorded. In 1994 alone, population will surpass 5.7 billion. The prospect of double-digit billions of people is worrisome, especially since these numbers may affect global warming, supplies of fresh water, destruction of rain forests, industrial pollution, and sustainable development. Yet, many indicators of quality of life show that people enjoy a better quality of life today than they did 100 years ago. Between India's independence and now, life expectancy increased by 20 years, infant mortality decreased 2-fold, literacy increased, and the food supply stabilized. Even though India's population has almost tripled since 1947, its economy increased rapidly and is 1 of the world's top 10 economies. University enrollment stands at 4.5 million. Agricultural production has exceeded demand. India represents the potential for human achievement through technological advancement and social organization. If the world's first national family planning program had been more successful when it began in 1952 in an India of 350 million people, India's population would be around 500 million instead of the expected 1 billion in 2000. All countries need to achieve a sustainable balance between human numbers and needs and natural resources. Family planning is an essential, cost-effective part of any development strategy. Family planning use has reduced fertility from 6 to 3.6 in developing countries. In 1965, only 8% used contraception, while more than 50% use it now. The most remarkable family planning/fertility reduction successes are Bangladesh, Brazil, Colombia, Indonesia, Mexico, and Thailand. Sufficient investment in family planning is needed if significant declines in fertility are to occur. More than 90% of the developing world's people are in countries with official family planning programs. Cost-effective assistance by donors and developing countries implementing

    Full Text Available Orbital pseudotumor is a benign disease involving the orbital structures. Pseudotumor of the ciliary body is rare. We present a case of a 27-year-old male who presented with gradual visual loss, pain, and redness in his left eye. On examination he was found to have a yellowish white mass at the periphery of anterior chamber in his left eye and ultrasound biomicroscopy (UBM revealed a ciliary body mass in the same eye. He was treated with systemic steroids, which was tapered over a period of 8 weeks. His symptoms improved and the ciliary body mass disappeared with no recurrence over the next 6 months. UBM is an important diagnostic tool for diagnosing ciliary body mass. Early diagnosis and prompt treatment with systemic steroids may help resolve pseudotumor of the ciliary body.

The history in global relations shows that without economic diplomacy there is no optimal economic growth and social development. It is important to note that economic diplomacy should be important for our country and the political elite, as well as for the administration of Croatian economic subjects that want to compete in international market economy. Comparative analysis are particularly highlighted by French experience. Therefore, Croatia should copy the practice of those countries that are successful in economic diplomacy. And in the curricula - especially of our economic faculties - we should introduce the course of Economic Diplomacy. It is important to note, that in order to form our optimal model of economic diplomacy which would be headed by the President of Republic of Croatia formula should be based on: Intelligence Security Agency (SOA, Intelligence Service of the Ministry of Foreign Affairs and European Integration, Intelligence Service of the Croatian Chamber of Commerce and the Intelligence Service of the Ministry of Economy, Labor and Entrepreneurship.

  6. The emergence of psychiatric semiology during the Age of Revolution: evolving concepts of 'normal' and 'pathological'.

    Science.gov (United States)

    Londoño, Diego Enrique; Dening, Tom

    2016-06-01

    This article addresses some important questions in psychiatric semiology. The concept of a sign is crucial in psychiatry. How do signs emerge, and what gives them validity and legitimacy? What are the boundaries of 'normal' and 'pathological' behaviour and mental experiences? To address these issues, we analyse the characteristics and rules that govern semiological signs and clinical elements. We examine 'normality' from the perspective of Georges Canguilehm and compare the differences of 'normal' in physiology and psychiatry. We then examine the history and the philosophical, linguistic and medical-psychiatric origins of semiology during the eighteenth and nineteenth centuries (the Age of Revolution). The field of rhetoric and oratory has emphasized the importance of passions, emotions and language as applied to signs of madness. Another perspective on semiology, provided by Michel Foucault, lays stress on the concept of 'instinct' and the axis of voluntary-involuntary behaviour. Finally, we analyse how statistics and eugenics have played an important role in our current conceptualization of the norm and therefore the scientific discourse behind the established clinical signs.

    Science.gov (United States)

    Featherstone, R.

    1983-05-01

    This paper describes a new method for calculating the acceleration of a robot in response to given actuator forces. The method is applicable to open-loop kinematic chains containing revolute and prismatic joints. The algorithm is based on recursive formulas involving quantities called articulated-body inertias, which represent the inertia properties of collections of rigid bodies connected together by joints allowing constrained relative motion between the bodies. A new, matrix-based notation is introduced to represent articulated-body inertias and other spatial quantities. This notation is used to develop the algorithm, and results in a compact representation of the equations. The new algorithm has a computational requirement that varies linearly with the number of joints, and its efficiency is compared with other published algorithms.

    In the cosmic allegorical interpretation of Shakespeare's "Hamlet" (BAAS 28, 859 & 1305, 1996; Mercury 26:1, 20, 1997; RPS 18:3, 6, 1997; Giornale di Astronomia 24:3, 27, 1998), the usurper King Claudius, namesake of Ptolemy, personifies geocentricity. Textual support for this reading is found in 1.2 where Hamlet is associated with the Sun, as befits a rightful heir, while Claudius is associated with the Earth. In 3.3 Claudius fears Hamlet's antics. Rosencrantz states that the lives of many depend on the well-being of the King. He warns that if the King were to be imperiled, his subjects, those "ten thousand lesser things", would fall in a "boisterous ruin" along with "each small annexment" and "petty consequence." These 10,000 lesser lights are the naked eye stars (mv ~ 6.5) which would collapse with the demise of the pre-Diggesian firmament, along with ancient planets and their geometrical contrivances. In 5.1 Shakespeare puns on "De revolutionibus" when he refers to "fine revolution." The double meaning of "revolution" (alteration, orbital motion) was in use long before 1600. Since "revolution" is used in the context of digging, it may refer as much to the Diggesian as the Copernican Revolution. Shakespeare's prescience is revealed by his anticipation of change, as encapsulated geocentricity is transformed to stellar boundlessness, while his presence is suggested by fatherly concerns and ghost-like direction.

    1997-11-01

    A new fabrication technique, derived from an earlier development to produce on- and off-axis optical surfaces of revolution is presented. Although based on a shape copying method, it is possible to generate different types of surfaces with the same machine tool. Load controlled point- contact machining is applied using a small tool which is guided along a pre-determined tool-path, not requiring an in-process tool-path control. This fabrication technique employs a self-correcting process and is characterized by an advantageous error propagation between tool and workpiece. The characteristics of this fabrication technique are discussed together with its application for the generation of on- and off-axis surfaces with conic sections as generators. The design of a first set-up for production of conic surfaces is presented with which it is possible to generate all kinds of conic surfaces on the same machine, featuring a pantograph enabling the production of different scales of the surfaces, together with the discussion of fist experimental data.

    Despite important human and financial resources and considerable accumulation of scientific publications, patents, and clinical trials, cancer research has been slow in achieving a therapeutic revolution similar to the one that occurred in the last century for infectious diseases. It has been proposed that science proceeds not only by accumulating data but also through paradigm shifts. Here, we propose to use the concept of 'paradigm shift' as a method of investigation when dominant paradigms fail to achieve their promises. The first step in using the 'paradigm shift' method in cancer research requires identifying its founding paradigms. In this review, two of these founding paradigms will be discussed: (i) the reification of cancer as a tumour mass and (ii) the translation of the concepts issued from infectious disease in cancer research. We show how these founding paradigms can generate biases that lead to over-diagnosis and over-treatment and also hamper the development of curative cancer therapies. We apply the 'paradigm shift' method to produce perspective reversals consistent with current experimental evidence. The 'paradigm shift' method enlightens the existence of a tumour physiologic-prophylactic-pathologic continuum. It integrates the target/antitarget concept and that cancer is also an extracellular disease. The 'paradigm shift' method has immediate implications for cancer prevention and therapy. It could be a general method of investigation for other diseases awaiting therapy.

    Full Text Available This article inserts itself into larger discussions regarding post-dictatorship memory politics in Portugal and comparative studies of similar histories of violence in Europe, particularly examinations of National-Socialism, Nazism and the Holocaust, as well as comparative studies of twentieth-century fascist dictatorships in the Iberian peninsula. In spite of the revolutionary, radical nature of the Portuguese democratisation process, studies conducted during the last four decades on the social and political (reconstructions of memory regarding the Portuguese dictatorship (1926-1974 have demonstrated that state policies regarding the past have depicted the dictatorship as one that is very similar to events in countries where the process of democratic transition was actually quite different from that of Portugal. Right-wing groups and those who self-describe as “victims” of processes of decolonisation that occurred between 1974 and 1975 have established a pattern of public debate that leaves no room for discussing the dictatorship without also referring to the 1974-1975 Revolution. This mode of debate seems to suggest that these two periods of history are indicative of a global regime phenomenon and that both the processes of decolonisation and revolution affected Portuguese society in similar ways. This paper attempts to complicate these narratives in order to question the democratic forms that emerged after the Revolution and to compare it to Salazar’s dictatorial regime.Este artículo se encuadra en una discusión más amplia sobre las políticas de la memoria de la posdictadura salazarista en Portugal, y en estudios comparados sobre historias semejantes de violencia en Europa, especialmente las relativas al nacional-socialismo, el nazismo y el Holocausto.

    Full Text Available The being philosophy of any organization depends on its human resources. Almost all scholars have been considered human resources as the most important factor. Therefore, human resources play a critical role in organizational development, and major organizational developments and changes derive from the unlimited intellectual abilities of this factor. Motivation is one of important instruments in inducing employees to produce effective and efficient results, and to create a positive work environment and to successfully execute the anticipated programs. Present research has been carried out for the purpose of measuring the effect of work motivation on job performance of employees in Islamic Revolution Housing Foundation, which has taken place in 2013. In this study, a sample containing 70 individuals was randomly selected according to Morgan table among the statistic population of 85 employees in Islamic Revolution Housing Foundation. Work motivation and job performance questionnaires were designed and the collected information were put into data analysis and hypothesis testing by using AMOS and SPSS software and the results show that the work motivation has a positive and significant effect on job performances of employees in Islamic Revolution Housing Foundation.

  6. The "Revolution in chemistry and physics." Overthrow of a reigning paradigm or competition between contemporary research programs?

    Science.gov (United States)

    Holmes, F L

    2000-12-01

    Recent revisionist interpretations of the chemical revolution have left intact the core of the traditional view that its central feature was the overthow of the phlogiston theory by the oxygen theory of combustion of Antoine Lavoisier. The central confrontation has been seen as that between the adherents of the chemical system that Lavoisier built around his theory and the form of the phlogiston theory defended by Joseph Priestley. This essay contends that Priestley's use of phlogiston was so loosely connected with the older phlogiston theories descended from that of Georg Ernst Stahl that the events at the heart of the chemical revolution should be viewed more as a competition between two rival new research programs than as the replacement of a reigning paradigm.

    The author deals with the issue of why quantum mechanics is so difficult to understand. The answer is identified here: the quantum formalism includes the principles of a radical revolution in epistemology. The development of these principles has led to an entire re-shaping of how to generate knowledge in sciences. It is a description of what lays behind quantum mechanics in terms of conceptualization.

    Otto Selz has been hailed as one of the most important precursors of the cognitive revolution, yet surprisingly few studies of his work exist. He is often mentioned in the context of the Würzburg School of the psychology of thinking and sometimes in the context of Gestalt psychology. In this paper, it is argued that Selz's emphasis on the role of problems and schemas in the direction of thought processes and creativity sets him apart from the program of the Würzburg School. On the other hand, by developing a theory of thinking that is exclusively at the intentional level, Selz also differs from psychologists that take physics as a model for psychology, such as the Gestalt psychology of Wolfgang Kihler. Special emphasis is given in this paper to Selz's use of the concept of problem or task and the concept of the schema. It is further argued that the concept of the schema is the result of Selz's adaptation of the theory of relations as developed by the philosopher Meinong. The paper begins with a sketch of Selz's life that ended so tragically.

    The first revolution in hearing aids came from nonlinear amplification, which allows better compensation for both soft and loud sounds. The second revolution stemmed from the introduction of digital signal processing, which allows better programmability and more sophisticated algorithms. The third revolution in hearing aids is wireless, which allows seamless connectivity between a pair of hearing aids and with more and more external devices. Each revolution has fundamentally transformed hearing aids and pushed the entire industry forward significantly. Machine learning has received significant attention in recent years and has been applied in many other industries, e.g., robotics, speech recognition, genetics, and crowdsourcing. We argue that the next revolution in hearing aids is machine intelligence. In fact, this revolution is already quietly happening. We will review the development in at least three major areas: applications of machine learning in speech enhancement; applications of machine learning in individualization and customization of signal processing algorithms; applications of machine learning in improving the efficiency and effectiveness of clinical tests. With the advent of the internet of things, the above developments will accelerate. This revolution will bring patient satisfactions to a new level that has never been seen before.

    Within the multibody dynamics framework, the paper proposed an efficient procedure to calculate revolute joint wear of planar mechanism with low velocity. Firstly, based on the wear test data, a method to calculate the wear coefficient that corresponds to the actual working condition of the mechanism is proposed. Then, an efficient iterative prediction method for joint clearance wear evolving in the multibody dynamic system in is proposed based on the Archard's wear model. Meanwhile, the wear tests of the typical mechanism have verified the method proposed in this paper. The research shows that when the increments of the wear depth of revolute joints are not big, the method can provide high prediction accuracy; however, as the predicted wear depth increases, the prediction error increases as well.

  11. The Identity Process in Times of Rupture: Narratives From the Egyptian Revolution

    Full Text Available This is a longitudinal study of the identity process through times of dramatic social change. Using a narrative psychological approach this research follows the life stories of five Egyptian bloggers as they write their stories on online blogs over the course of the three years following the 2011 revolution, at which time Egypt has witnessed major social and political changes. The aim is to understand the identity process of individuals as they develop and adapt through changing social contexts and how they create alternative social relations as they engage in prefigurative politics. The findings shed light on how ruptures trigger a process of reflexivity, adaptive learning, and sense-making that facilitates coping and the reconstruction of a positive identity after ruptures. It also suggests that the narration of the experience of rupture through storytelling creates a heightened sense of agency in individuals’ ability to create new meanings of their world in spite of the socio-cultural and political constraints. This study presents narratives as an informing methodological resource that connects identity process with social representations and emphasizes the value of storytelling as an integral part of the adaptation process.

  12. Political System of the Great Cultural Revolution Reflected in Misty Poetry

    Full Text Available The article outlines Chinese literature following the establishment of the People’s Republic of China in relation to Mao’s Communist policy. It presents the occurrence of Misty poetry as an opposition to the political ideology of the Great Cultural Revolution (1966–1976. Misty poetry is understood as a spontaneous illegal poetic movement of individuals who veiled their political demands directed against Mao’s ideology in metaphors. This oppositional stance resembled the movement of 4th May 1919 which took place after the collapse of the last Chinese dynasty and criticised the traditional dominant ideology of Confucianism and sought democratization of the Chinese society. The same desire was shared by the Misty poets but this time under the dominance of the political ideology of the Chinese Communist Party in the period following 1942 which was indicated by Mao Zedong in his speech in Yan’an. Mao’s policy was repressive in nature since the role of literature and art, and thereby also poetry, was seen only as being utilitarian and was thus sealed in the dictated reflection of the class struggle. Therefore, in essence, the communist period laid its path to capitalism.

  13. A new sexual revolution? Critical theory, pornography, and the Internet.

    2011-08-01

    The "sexual revolution" was a central element of North American culture in the 1960s. Today, sex is increasingly central to mainstream culture, in large part due to the Internet, and we might wonder whether we are living through a comparable period of sexual history. In this article, I revisit the work of Herbert Marcuse-the original theorist of the sexual revolution-to ask whether it can contribute to a critical theory of sexuality in the era of digital technology. After outlining Marcuse's theory of the role of Eros in social life, I discuss two pornographic Web sites that combine eroticism and social critique. I argue that Marcuse's work is valuable for its emphasis on the intersection of sex, technology, and capitalist economy, but that it needs to be supplemented by a focus on masculinity and the male body in Internet pornography.

    Full Text Available The Arab Spring has generated unprecedented attention to the Arab world in Western news media. This paper presents a comparative study of Danish press coverage of the uprisings in Tunisia and Syria during the early months of the Arab Spring (January-March 2011. The study is based on a mixed quantitative and qualitative content analysis aimed at identifying patterns of news reporting of the Arab Spring. The investigation looks into whether temporal developments of the Arab revolutions, the level of journalistic presence in the region, and national differences influence Danish press coverage of the Arab Spring. The findings indicate that media coverage of the Arab Spring points in different directions. On the one hand there has been a remarkable increase in media attention to the Middle East in purely quantitative terms. On the other hand the study finds that a number of traditional media patterns persist, not least in relation to media perceptions of Islam and democracy, the Arab-Israeli conflict, and the ability to reform the Arab world from the inside.

    Full Text Available The emerging Knowledge Revolution goes beyond the changing technologies and the challenges and opportunities they create to include the structure of knowledge and how it is transmitted inter-generationally and across countries. There are seven major features of that profound transformation, which I call “The Seven Pillars of the New Knowledge Revolution”. These are: (i Parsing, Life & Organization; (ii Image & Text; (iii Humans & Machines; (iv Complexity & Chaos; (v Computation & Research; (vi Convergence & Transformation; and (vii Pluridisciplinarity & Policy. This diagnosis has profound implications on how one should think about the design and management of our institutions of learning, starting not only with universities, but also the school system, as well as our research institutions (whether in universities or in public and private labs, and the supporting institutions of knowledge (like museums, libraries and archives. Radical proposals are advanced for the content, method, participants and organizational setting of education, as well as the role of the University as mediator of transitions, its relationship with society and economy, as well as its physical presence, governance structure and the values it should promote. Core functions and curricula for the future, along with the possibility of a global university consortium, are discussed.

  17. Molecular clocks indicate turnover and diversification of modern coleoid cephalopods during the Mesozoic Marine Revolution.

    Coleoid cephalopod molluscs comprise squid, cuttlefish and octopuses, and represent nearly the entire diversity of modern cephalopods. Sophisticated adaptations such as the use of colour for camouflage and communication, jet propulsion and the ink sac highlight the unique nature of the group. Despite these striking adaptations, there are clear parallels in ecology between coleoids and bony fishes. The coleoid fossil record is limited, however, hindering confident analysis of the tempo and pattern of their evolution. Here we use a molecular dataset (180 genes, approx. 36 000 amino acids) of 26 cephalopod species to explore the phylogeny and timing of cephalopod evolution. We show that crown cephalopods diverged in the Silurian-Devonian, while crown coleoids had origins in the latest Palaeozoic. While the deep-sea vampire squid and dumbo octopuses have ancient origins extending to the Early Mesozoic Era, 242 ± 38 Ma, incirrate octopuses and the decabrachian coleoids (10-armed squid) diversified in the Jurassic Period. These divergence estimates highlight the modern diversity of coleoid cephalopods emerging in the Mesozoic Marine Revolution, a period that also witnessed the radiation of most ray-finned fish groups in addition to several other marine vertebrates. This suggests that that the origin of modern cephalopod biodiversity was contingent on ecological competition with marine vertebrates.

    Recent studies of the micro-dynamic behavior of a deployable telescope metering truss have identified instabilities in the equilibrium shape of the truss in response to low-energy dynamic loading. Analyses indicate that these micro-dynamic instabilities arise from stick-slip friction within the truss joints (e.g., hinges and latches). The present study characterizes the low-magnitude quasi-static load cycle response of the precision revolute joints incorporated in the deployable telescope metering truss, and specifically, the hysteretic response of these joints caused by stick-slip friction within the joint. Detailed descriptions are presented of the test setup and data reduction algorithms, including discussions of data-error sources and data-filtering techniques. Test results are presented from thirteen specimens, and the effects of joint preload and manufacturing tolerances are investigated. Using a simplified model of stick-slip friction, a relationship is made between joint load-cycle behavior and micro-dynamic dimensional instabilities in the deployable telescope metering truss.

    2017-02-01

    The development of rehabilitation has traditionally focused on measurements of motor disorders and measurements of the improvements produced during the therapeutic process; however, physical rehabilitation sciences have not focused on understanding the philosophical and scientific principles in clinical intervention and how they are interrelated. The main aim of this paper is to explain the foundation stones of the disciplines of physical therapy, occupational therapy, and speech/language therapy in recovery from motor disorder. To reach our goals, the mechanistic view and how it is integrated into physical rehabilitation will first be explained. Next, a classification into mechanistic therapy based on an old version (automaton model) and a technological version (cyborg model) will be shown. Then, it will be shown how physical rehabilitation sciences found a new perspective in motor recovery, which is based on functionalism, during the cognitive revolution in the 1960s. Through this cognitive theory, physical rehabilitation incorporated into motor recovery of those therapeutic strategies that solicit the activation of the brain and/or symbolic processing; aspects that were not taken into account in mechanistic therapy. In addition, a classification into functionalist rehabilitation based on a computational therapy and a brain therapy will be shown. At the end of the article, the methodological principles in physical rehabilitation sciences will be explained. It will allow us to go deeper into the differences and similarities between therapeutic mechanism and therapeutic functionalism.

  20. Widespread pollution of the South American atmosphere predates the industrial revolution by 240 y.

    In the Southern Hemisphere, evidence for preindustrial atmospheric pollution is restricted to a few geological archives of low temporal resolution that record trace element deposition originating from past mining and metallurgical operations in South America. Therefore, the timing and the spatial impact of these activities on the past atmosphere remain poorly constrained. Here we present an annually resolved ice core record (A.D. 793-1989) from the high-altitude drilling site of Quelccaya (Peru) that archives preindustrial and industrial variations in trace elements. During the precolonial period (i.e., pre-A.D. 1532), the deposition of trace elements was mainly dominated by the fallout of aeolian dust and of ash from occasional volcanic eruptions, indicating that metallurgic production during the Inca Empire (A.D. 1438-1532) had a negligible impact on the South American atmosphere. In contrast, a widespread anthropogenic signal is evident after around A.D. 1540, which corresponds with the beginning of colonial mining and metallurgy in Peru and Bolivia, ∼240 y before the Industrial Revolution. This shift was due to a major technological transition for silver extraction in South America (A.D. 1572), from lead-based smelting to mercury amalgamation, which precipitated a massive increase in mining activities. However, deposition of toxic trace metals during the Colonial era was still several factors lower than 20th century pollution that was unprecedented over the entirety of human history.

  1. The edge of expertise: Representing barefoot doctors in Cultural Revolution China.

    2015-01-01

    ‘Barefoot doctors’ were designed as an innovative task force during the Cultural Revolution (1966-1976) to provide health care to rural villages in China. Without formal training that would identify the group professionally, barefoot doctors were at once amateur medical practitioners and expert revolutionary actors in Communist Party propaganda. At stake in legitimating revolutionary medicine was allowing revolutionary spirit to supplement for minimal medical training. As a result, the symbolic power of representing barefoot doctors rested in showcasing their devotion to enhancing access to health care in rural China. These representations followed an intensifying militarization of civilians, embracing the barefoot doctor’s ability to survive any obstacle while also celebrating those who died in the process. This paper examines three public portrayals of barefoot doctors, arguing that conflicting idealizations of rural epistemology combined the opposing elements of self-cultivation and self-annihilation to unite the identity of an emerging group of amateur doctors and illustrate acceptable forms of medical and revolutionary expertise.

    A number of studies have pointed to a plateauing of athletic performance, with the suggestion that further improvements will need to be driven by revolutions in technology or technique. In the present study, we examine post-war men's Olympic performance in jumping events (pole vault, long jump, high jump, triple jump) to determine whether performance has indeed plateaued and to present techniques, derived from models of human growth, for assessing the impact of technological and technical innovation over time (logistic and double logistic models of growth). Significantly, two of the events involve well-documented changes in technology (pole material in pole vault) or technique (the Fosbury Flop in high jump), while the other two do not. We find that in all four cases, performance appears to have plateaued and that no further "general" improvement should be expected. In the case of high jump, the double logistic model provides a convenient method for modelling and quantifying a performance intervention (in this case the Fosbury Flop). However, some shortcomings are revealed for pole vault, where evolutionary post-war improvements and innovation (fibre glass poles) were concurrent, preventing their separate identification in the model. In all four events, it is argued that further general growth in performance will indeed need to rely predominantly on technological or technical innovation.

    The small hydroelectric power station of Rupboden in the Oberfranken district was reactivated after having been decommissioned for 30 years. This new low pressure plant consists of an open-flume turbine with an adjustable diffusor and a firm rotor disk (propeller) with a vertical rod. A large range of operation at a constant height of fall is ensured by a variable revolution number. The profiles of the adjustable diffusor and rotor disk and the design of the draft tube were optimized using numerical flow calculation. First operating experience is very positive. The turbine runs extremely smoothly over the entire range. (orig.) [Deutsch] Das Kleinwasserkraftwerk Rupboden in Oberfanken wurde nach 30 Jahren Stillstand reaktiviert.

    Matrix-assisted laser desorption ionization time-of-flight (MALDI-TOF) mass spectrometry (MS) represents a revolution in routine pathogen identification in clinical microbiology laboratories. A MALDI-TOF MS was introduced to tropical Africa in the clinical microbiology laboratory of the Hôpital Principal de Dakar (Senegal) and used for routine pathogen identification. Using MS, 2,429 bacteria and fungi isolated from patients were directly assayed, leading to the identification of 2,082 bacteria (85.7%) and 206 fungi (8.5%) at the species level, 109 bacteria (4.5%) at the genus level, and 16 bacteria (0.75%) at the family level. Sixteen isolates remained unidentified (0.75%). Escherichia coli was the most prevalent species (25.8%) followed by Klebsiella pneumoniae (14.8%), Streptococcus agalactiae (6.2%), Acinetobacter baumannii (6.1%), Pseudomonas aeruginosa (5.9%), and Staphylococcus aureus (5.9%). MALDI-TOF MS has also enabled the detection of rare bacteria and fungi. MALDI-TOF MS is a powerful tool for the identification of bacterial and fungal species involved in infectious diseases in tropical Africa.

  5. The dispersion of pederasty and the athletic revolution in sixth-century BC Greece.

    2005-01-01

    Dorian Crete and Thebes are conventionally seen by ancient sources as the originators of pederasty; modern historians see support for this view in Dorian male-centered militarism and sexual segregation in upbringing. Here athletic culture, including training, nudism, and competition, is argued to be a chief 'trigger' for the emergence of pederasty in Sparta and its relatively rapid spread to other Greek states in the seventh to sixth centuries BC. Athletic nudity, in particular, was not a device to enforce civic egalitarianism, as some have argued, but is a persistently erotic incentive that reinforces hegemonic maleness and advertises the individual's virtuous exercise of restraint. In particular, Sparta is found to be the likely source of generalized athletic nudity combined with open pederasty in the early seventh century BC. Nudism in Greek art is erotically charged and not, as others argue, simply a gender marker in the seventh century. Generalized athletic nudity spread to other Greek states emulating the successful Spartan model by the 'athletic revolution' of the early sixth century. With athletic nudity, open pederasty, again following Sparta, was fostered.

    1991-11-01

    This article describes the traditional concepts and treatment of mental disorders in the Oromo areas in western Ethiopia before the revolution in 1974. There are three traditional cultural influences operating: traditional Oromo thinking, the Coptic church and the Islamic culture. One important element in traditional Oromo thinking is that each person is believed to possess an ayana, which is a special divine agent that can descend upon people, but also means a person's character and personality. In the traditional Oromo society, the Kallu is the religious leader who, through an ecstatic ritual technique, can investigate the causes of the disorder and advise what to do. Mental disorders are generally explained as resulting from disturbances in the relationship between people and divinity. The second important cultural element in western Ethiopia is the orthodox Coptic church, which usually looks upon mental disorders as possession by evil spirits, which are thus treated by specially gifted priests and monks by praying and giving holy water or eventually exhortation. According to Islamic teaching in the area, mental disorders are caused by evil spirits sent by God to punish the unfaithful people. Some Muslim sheiks treat mental cases with prayers, but herbal remedies are also used. There is a great intermingling of these different cultural and religious elements and people attend different healers and religious leaders more depending on the reputation of the person than on cultural and religious affiliation.

    During the French Revolution and Napoleon's campaigns, above-knee or below-knee amputations were performed either immediately or with a delay, which favoured septic problems. A rapidly operated amputation by a well-trained surgeon was the best way to save the life of a soldier who suffered from an open comminuted fracture of a limb. The conditions on military campaigns were indeed hard ones: doctors and surgeons had practically no resources and the transportation of severely injured persons was difficult. Such conditions favoured the pain and the danger caused by an injury, and it was rather impossible for the medical corps to lavish repeated treatments on the wounds. The amputated soldiers were then given prostheses: either a traditional peg-leg, with a flexed knee joint for trans-tibial amputations, or an "imitative" prosthesis, which tended to look like a real leg with eventually an articulated knee or foot. The author mentions famous or unrecognized amputated men, describing significant events.

    We study the natural vibrations and the dynamic stability of nearly cylindrical orthotropic shells of revolution subjected to meridional forces uniformly distributed over the shell ends. We consider shells of medium length for which the shape of the midsurface generatrix is described by a parabolic function. Using the theory of shallow shells, we obtain the resolving equation for the vibrations of the corresponding prestressed shell. In the isotropic case, this equation differs from the well-known equation [1] by an additional term, which can be of the same order as the other terms taken into account. We consider shells of both positive and negative Gaussian curvature. We assumed that the shell ends are freely supported. The formulas and universal curves describing the dependence of the minimum frequency, the wave generation shape, and the dynamic instability domain boundaries on the orthotropy parameters, the preliminary stress, the Gaussian curvature, and the amplitude of the shell deviation from the cylinder are given in dimensionless form. We find that in the case of prestresses the orthotropy parameters and the shell deviation from the cylinder (of the order of thickness) can significantly change the least frequencies, the wave generation shape, and the dynamic instability domain boundaries of the corresponding prestressed orthotropic cylindrical shell. In this case, we note that for convex shells under preliminary compression the influence of the elastic parameter in the axial direction is stronger than the influence of the elastic parameter in the circular direction, while the situation is opposite in the case of concave shells. In the case of preliminary extension, the leading role of any orthotropy parameter can vary depending on the value of the preliminary stress and the Gaussian curvature.

    The article takes hedonism and revolution as a vantage point to discuss the Kommune 2, an experiment in collective living, the anti-authoritarian kindergardens for the under-fives, and, last but not least, a speech in 1968 that spurred the women's movement in Western Germany. The author's interest is on the materials documenting how the Berlin student movement saw psychoanalysis: One point was that the pleasure principle should replace the reality principle for the sake of humankind, another that the authoritarian character structure has its roots in the denial of sexuality. Kindergarden children supposedly need "de-individualized identification" to develop ego-strength, when boys and girls differ in their superego organization. An important accomplishment was a group analysis conducted without an analyst, an experiment that worked amazingly well in the Kommune 2. In all, these various experiments in emancipation, with psychoanalysis a guide to interpersonal understanding, may be deemed spectacular when their aftereffects on everyday life in Germany have been tremendous.

    Visual analysis of faces and nonfacial body stimuli brings about neural activity in different cortical areas. Moreover, processing body form and body action relies on distinct neural substrates. Although brain lesion studies show specific face processing deficits, neuropsychological evidence for defective recognition of nonfacial body parts is lacking. By combining psychophysics studies with lesion-mapping techniques, we found that lesions of ventromedial, occipitotemporal areas induce face and body recognition deficits while lesions involving extrastriate body area seem causatively associated with impaired recognition of body but not of face and object stimuli. We also found that body form and body action recognition deficits can be double dissociated and are causatively associated with lesions to extrastriate body area and ventral premotor cortex, respectively. Our study reports two category-specific visual deficits, called body form and body action agnosia, and highlights their neural underpinnings.

    Full Text Available Paper presents a family of helical two-revolutional cyclical surfaces, which arecreated by movement of the circle alongside the helical cycloidal curve, where circle islocated in the curve normal plane and its centre is on this curve. Helical cycloidal curvecan be created by simultaneous revolution of a point about two different axes 3o, 2o and byscrewing about axis 1o in the space. Form of the helical cycloidal curve and also of thehelical two-revolutional cyclical surface is dependent on the relative position of the threeaxes of revolutions, on multiples of angular velocities and orientations of separaterevolutions. Analytic representation, classification of surfaces and some of their geometricproperties are derived.

    A revolution is defined as a "drastic and far-reaching change in the way of thinking and behaving", and this describes the effect that the IRIS Data Management System (DMS) has had in the framework of seismological research. The IRIS Data Management Center (DMC) prototype began operation at theUniversity of Texas at Austin in 1988 and has evolved to to a fully functioning facility at the University of Washington in Seattle. The focus of this submission is to share an historical timeline of events related to the DMC, a bit of scrap-booking perhaps, centered around the business of waveform data management conducted by IRIS and it's partners. We hope to illustrate how the successful philosophy of sharing unrestricted data, openly collaborating with a global network of networks, and partnering with computer and software industry vendors that have supported our community's academic research, has enabled generations of seismologists to both curate and continually "mine" the ever-growing 45 years of digital data currently stored in the perpetual archive located in Seattle, WA. At the time that the Loma Prieta Earthquake shook and burned San Francisco on October 17, 1989, there were only 3 stations which had dial-up modems enabling what then was considered "fast access" to waveform data delivery from them back to the DMC. This was considered the first test of the DMC, since waveform data were collected and distributed within days of this event. But this was only a foretelling of things to come, since the rates of archiving and distribution have continually grown to a current 1900+ stations and a 17,000+ channel count of real-time data streaming in and out of the DMC daily, totaling 50 Terabytes of data shipped in 2009 alone. We will attempt to summarize the important technological challenges, solutions, and growth of the DMC with the goal of illustrating that "if you build it, they will come", and how this could be useful to other organizations.

    The current species extinction crisis is being exacerbated by an increased rate of emergence of epizootic disease. Human-induced factors including habitat degradation, loss of biodiversity and wildlife population reductions resulting in reduced genetic variation are accelerating disease emergence. Novel, efficient and effective approaches are required to combat these epizootic events. Here, we present the case for the application of human precision medicine approaches to wildlife medicine in order to enhance species conservation efforts. We consider how the precision medicine revolution, coupled with the advances made in genomics, may provide a powerful and feasible approach to identifying and treating wildlife diseases in a targeted, effective and streamlined manner. A number of case studies of threatened species are presented which demonstrate the applicability of precision medicine to wildlife conservation, including sea turtles, amphibians and Tasmanian devils. These examples show how species conservation could be improved by using precision medicine techniques to determine novel treatments and management strategies for the specific medical conditions hampering efforts to restore population levels. Additionally, a precision medicine approach to wildlife health has in turn the potential to provide deeper insights into human health and the possibility of stemming and alleviating the impacts of zoonotic diseases. The integration of the currently emerging Precision Medicine Initiative with the concepts of EcoHealth (aiming for sustainable health of people, animals and ecosystems through transdisciplinary action research) and One Health (recognizing the intimate connection of humans, animal and ecosystem health and addressing a wide range of risks at the animal-human-ecosystem interface through a coordinated, collaborative, interdisciplinary approach) has great potential to deliver a deeper and broader interdisciplinary-based understanding of both wildlife and human

  20. The Revolution in Viral Genomics as Exemplified by the Bioinformatic Analysis of Human Adenoviruses

    Full Text Available Over the past 30 years, genomic and bioinformatic analysis of human adenoviruses has been achieved using a variety of DNA sequencing methods; initially with the use of restriction enzymes and more currently with the use of the GS FLX pyrosequencing technology. Following the conception of DNA sequencing in the 1970s, analysis of adenoviruses has evolved from 100 base pair mRNA fragments to entire genomes. Comparative genomics of adenoviruses made its debut in 1984 when nucleotides and amino acids of coding sequences within the hexon genes of two human adenoviruses (HAdV, HAdV–C2 and HAdV–C5, were compared and analyzed. It was determined that there were three different zones (1-393, 394-1410, 1411-2910 within the hexon gene, of which HAdV–C2 and HAdV–C5 shared zones 1 and 3 with 95% and 89.5% nucleotide identity, respectively. In 1992, HAdV-C5 became the first adenovirus genome to be fully sequenced using the Sanger method. Over the next seven years, whole genome analysis and characterization was completed using bioinformatic tools such as blastn, tblastx, ClustalV and FASTA, in order to determine key proteins in species HAdV-A through HAdV-F. The bioinformatic revolution was initiated with the introduction of a novel species, HAdV-G, that was typed and named by the use of whole genome sequencing and phylogenetics as opposed to traditional serology. HAdV bioinformatics will continue to advance as the latest sequencing technology enables scientists to add to and expand the resource databases. As a result of these advancements, how novel HAdVs are typed has changed. Bioinformatic analysis has become the revolutionary tool that has significantly accelerated the in-depth study of HAdV microevolution through comparative genomics.

    The Anthropocene colloquially refers to a global regime of human-caused environmental modification of earth systems associated with profound changes in patterns of human mobility, as well as settlement and resource use compared with prior eras. Some have argued that the processes generating the Anthropocene are mainly associated with population growth and technological innovation, and thus began only in the late Holocene under conditions of dense sedentism and industrial agriculture.(1) However, it now seems clear that the roots of the Anthropocene lie in complex processes of intensification that significantly predate transitions to agriculture.(2,3) What intensification is remains less clear. For some it is increasing economic productivity that increases carrying capacity, the drivers of which may be too diverse and too local to generalize.(4,5) For others using Boserup's ideas about agrarian intensification, increasing density in hunter-gatherer populations can produce declines in subsistence efficiency that increase incentives for investing labor to boost yield per unit area, which then elevates Malthusian limits on carrying capacity.(6-8) As Morgan(9) demonstrates in a comprehensive review, the legacy of such Boserupian intensification is alive, well, and controversial in hunter-gatherer archeology. This is a result of its potential for illuminating processes involved in transformations of forager socio-political and economic systems, including those dominated by harvesting more immediate-return resources and high residential mobility as well as those characterized by more delayed-return material economies with reduced residential mobility, a broader spectrum of resources, degrees of storage, and greater social stratification. Here we detail hypotheses about the processes involved in such transitions and explore the way that anthropogenic disturbance of ecosystems, especially the use of landscape fire, could be fundamentally entangled with many broad

    The article presents results of analysis of works of late XIX--first quarter of XY centuries devoted to problems of social hygiene. It is established that origin of social hygiene was directly related to crucial revision of conceptions of causes and essence of diseases that created necessary conditions for transfer into medicine ideas and methods of political economy, sociology and eugenics. It is proved that origin of social hygiene was appropriate consequence of those crucial alterations in mass physician's consciousness that characterize scientific revolution in medicine of late XIX--first half XX centuries.

  3. The Disquieting Revolution: A Genealogy of Reason and Racism in the Québec Press

    2011-01-01

    Full Text Available Within the past decade, a series of contentious events concerning the accommodation of different cultural and religious traditions and practices in Quebec has incited much debate in this region. Labelled the “reasonable accommodation” issue by the local press, this controversy, which has its roots in neo-nationalist sentiments born of the Quiet Revolution, has incited responses ranging from denunciations of racist discrimination to calls for more stringent measures to ensure the assimilation of non-Westerners into Québécois culture. As Monika Kin Gagnon points out, this concept has moved beyond its legal origins to become a “social discourse” in the culture at-large, in that many in Quebec are vocally expressing their anxieties over the idea that the rights of newcomers has reached a tipping point, whereby the limits of reason are now over-stretched, weakening the dominant population’s values and identity. Much of this fear was stoked by certain stakeholders in the 2007 Quebec election, namely politicians and media outlets, when reasonable accommodation was highlighted as a major issue. This paper provides an analysis of that election and the campaigns leading into it, revealing how the press and the leaders of the three major political parties were complicit in transforming some negligible and private incidents into a greater menace endangering the very existence of Quebec society. By tracing the genealogy of “the reasonable Québécois”, I will demonstrate how reason and racism became intertwined during the course of this debate over rights, identity, and citizenship in Quebec.

    Technological cycles have been characterized as the basis of long and continuous periods economic growth through sustained changes in total factor productivity. While this hypothesis is in part consistent with several theories of growth, the sheer magnitude and length of the economic revolutions experienced by humankind seems to indicate surmise that more attention should be given to the origin of major technological and economic changes, with reference to one crucial question: role of production and use of energy in economic development.

  5. CRISES AND REVOLUTION

    Directory of Open Access Journals (Sweden)

    Adrián Sotelo Valencia

    2010-01-01

    Full Text Available This article addresses the materialist theory of development and fall of Marxism based on the theory of value as originally considered and presented by Karl Marx in Grundrisse and in Crítica da Economia Política, claiming that the production of value depends on labor force. As it takes place today, capital displaces labor force in every industry, service and activity, country, territory and region all over the world; workers are dismissed and are transferred to speculative activities of the fictional capital. This lesser disposition of labor force eventually harms the mean profit rate and, as time goes by, it provokes a crisis. The present capitalist crisis is resultant from the insufficiency and, to certain extent, to the incapacity of mechanisms from the system to generate enough value production in the labor process, to provide value to the invested capital (in settings of production, raw matter, and in labor force or variable capital; to create more value and to regain increased profit rate. These restraints of the financial capital (fictional capital cause a deviation to the speculative plan and contribute for the formation of tragic speculative bubbles in sectors such as those of housing, energy and food. No matter how much productivity is increased, developing a technological revolution and “sparing labor force”, the reduction of time, socially required for the production of goods and labor force, becomes harder and more marginal. This is the way the capitalist system enters a civilian, structural and organic crisis, as it is now. To go beyond the capital means to construct structures and superstructures of a new non-capitalist society based on a new way to produce, to work and to keep harmonious and friendly human social relations. It is difficult to have a successful revolution if not with the education of its agents, that is, the organized front people, parties and syndicates that will raise the social, political and cultural

    Global climate change mitigation and CO2 emission reduction have promoted the revolutionary transformation in energy system.The core content of energy system revolutionary transformation is to replace the high-carbon energy system dominated by fossil energy with low-carbon energy system dominated by new and renewable energy and finally realize the near-zero emission of CO2.The new energy system transformation has also led to a reform in global economic and social development patterns.Developing low-carbon economy becomes the fundamental strategy of sustainable development under climate risk management and the only solution to getting on the road from industrial civilization to ecological civilization.China intends to achieve the peaking of CO2 emissions around 2030 and increase the share of non-fossil fuels in primary energy consumption to around 20% by 2030.Guided by the targets,China directs its economy development to a low-carbon pattern.Therefore,new and renewable power capacity need to reach 1300 GW,and the electricity generated should be 4 times of that in 2013 with a continuous increase rate of 6%e8% around 2030.The pace of energy substitution need to be accelerated and efficient,safe,clean,and low-carbon energy supply and consumption systems should be established besides strengthened energy conservation and improved energy efficient.Therefore,reform need be deepened,favorable policy system and market mechanism for energy revolution and low-carbon development need be established,energy pricing mechanism should be reformed,and national carbon market should be formed to provide a favorable policy and market environment for low-carbon technology innovation and industry development.

    2014-01-01

    Was there a Darwinian Revolution and was it but part of the Scientific Revolution? Before Thomas Kuhn's Structure of Scientific Revolutions in 1962, most people thought that there was a Darwinian Revolution, that it was in some sense connected to the Scientific Revolution, but that neither question nor answer was terribly interesting. Then revolutions in science became a matter of intense debate, not so much about their very existence but about their nature. Was there a switch in world-views? Did the facts change? What was the importance of social groups? And so forth. Recently however some students of the history of science have started to argue that the very questions are misconceived and that there cannot have been a Darwinian Revolution and its relationship to the Scientific Revolution is imaginary because there are no such revolutions in science! This paper takes a sympathetic look at these issues, concluding that there is still life in the revolution-in-science issue, that Kuhn's book was seminal and still has things of importance to say, but that matters are more complex and more interesting than we thought back then.

  13. Complexity as AN Epistemic Revolution: Considerations on the New Science in the Context of Western Intellectual History

    Science.gov (United States)

    Popolo, Damian

    The paper will seek to present a genesis of complexity in European philosophical thought. Following the works of Gleick and Hobsbawn it is possible to discern the emergence of complexity's ethos in the `age of revolutions'. Gleick, for example, has noted the influence of natural philosophy on the first precursors of chaos theory. Natural philosophy itself was deeply anchored in German romanticism. The paper will thus seek to present, following Foucault, an `Archaeology of Complexity' which considers Foucault's definition of epistemes as evolving modes of thought. In particular, the paper will seek to use Foucault's description of the modern episteme in order to detect the novelty inherent within the ethos of Complexity.

  17. Revolution rather than rotation of AAA+ hexameric phi29 nanomotor for viral dsDNA packaging without coiling.

    Schwartz, Chad; De Donatis, Gian Marco; Zhang, Hui; Fang, Huaming; Guo, Peixuan

    2013-08-15

    It has long been believed that the DNA-packaging motor of dsDNA viruses utilizes a rotation mechanism. Here we report a revolution rather than rotation mechanism for the bacteriophage phi29 DNA packaging motor. The phi29 motor contains six copies of the ATPase (Schwartz et al., this issue); ATP binding to one ATPase subunit stimulates the ATPase to adopt a conformation with a high affinity for dsDNA. ATP hydrolysis induces a new conformation with a lower affinity, thus transferring the dsDNA to an adjacent subunit by a power stroke. DNA revolves unidirectionally along the hexameric channel wall of the ATPase, but neither the dsDNA nor the ATPase itself rotates along its own axis. One ATP is hydrolyzed in each transitional step, and six ATPs are consumed for one helical turn of 360°. Transition of the same dsDNA chain along the channel wall, but at a location 60° different from the last contact, urges dsDNA to move forward 1.75 base pairs each step (10.5bp per turn/6ATP=1.75bp per ATP). Each connector subunit tilts with a left-handed orientation at a 30° angle in relation to its vertical axis that runs anti-parallel to the right-handed dsDNA helix, facilitating the one-way traffic of dsDNA. The connector channel has been shown to cause four steps of transition due to four positively charged lysine rings that make direct contact with the negatively charged DNA phosphate backbone. Translocation of dsDNA into the procapsid by revolution avoids the difficulties during rotation that are associated with DNA supercoiling. Since the revolution mechanism can apply to any stoichiometry, this motor mechanism might reconcile the stoichiometry discrepancy in many phage systems where the ATPase has been found as a tetramer, hexamer, or nonamer.

    A new approach is proposed for study structure and properties of the total squared mean curvature $W$ of surfaces in ${\\bf R}^3$. It is based on the generalized Weierstrass formulae for inducing surfaces. The quantity $W$ (Willmore functional) is shown to be invariant under the modified Novikov--Veselov hierarchy of integrable flows. The $1+1$--dimensional case and, in particular, Willmore tori of revolution, are studied in details. The Willmore conjecture is proved for the mKDV--invariant Willmore tori.

    Revolutions in modem world history were also events with ideological significances, and the writing of the history of those revolutions usually displayed some complicated connections with ideologies. There is an obvious transition from "Whiggish paradigm" to "new historiography of the American Revolution" in the historical narration of the American Revolution in the United States. In this process, the Revolution has been transformed from a political revolution led by "the Founding Fathers" into overall revolutions with the ordinary people and marginalized groups as leading roles. In this transformation, ideologies like populism, multicuhuralism, and feminism subtly interacted with historical writing of the Revolution. This reconstructed history of the American Revolution, which is imbued with ideological tints, has moved from the academic periphery to the center, and put new energies into various radicalisms in current America. But however, it is only one of the contested versions of the historical narration of the American Revolution.%世界近现代史上的革命往往也是一种意识形态事件,而革命史写作与意识形态之间有着复杂的关联。美国史学界关于美国革命的历史叙事,经历了从“辉格主义范式”向“新美国革命史学”的转变,这场革命也从“建国之父”领导的政治革命,被改写成了一场由普通民众和边缘群体扮演主角的全面变革。在这一转变中,平民主义、多元文化主义和女性主义等思潮与革命史写作之间发生了微妙的互动。这种经过重构的美国革命史带有浓厚的意识形态色彩,已经从学术的边缘走向了中心,并为当前美国社会各种激进的意识形态提供了新的能量。但它仍只是美国革命史的众多相互竞争的版本中的一个。

    For four years the National Science Foundation (NSF)-sponsored TeXas Earth and Space Science (TXESS) Revolution professional development program has helped teachers build a solid foundation in the geosciences through guided inquiry activities and lectures delivered by science experts. The professional development program comprises eight professional development academies and two summer institutes. Climate literacy has been a cross-cutting theme throughout the series of academies and institutes. Although we present a special emphasis on climate literacy in the 7th academy on Climate Change, the 8th academy on Humans at the Helm and the 2nd summer institute module on climate mitigation technology, activities related to climate literacy are woven into each academy. Examples of climate as a cross-cutting theme include a module on water and drought, including research on climate change through the analysis of deep-sea cores, and the effects on the Mayan population. Our distinguished lecturers bring in climate literacy as part of their presentations and programs: our Poking Holes into the Planet and Team Science professional development academy included two distinguished lecturers who brought current research results and educational materials from the ANDRILL (Antarctic Geological Drilling) program and the Integrated Ocean Drilling Program. Our Earth as a Habitable Planet professional development academy featured an activity on corals that used data to explore how higher than normal sea surface temperatures contribute to coral bleaching events. TXESS Revolution also works with our teachers to link them with other opportunities aligned with our professional development goals. With our assistance, one of our TXESS Revolution teachers sailed as part of the science team on Integrated Ocean Drilling Program expedition 317 to investigate sea level fluctuations in the Canterbury Basin offshore New Zealand, creating various resources (e.g., podcasts, blogs) to multiply the

    In this research, we study the effects of tourism policy-making in the Pre and Post Islamic revolution (1979) in Iran with a comparative approach. The case study of research is Babolsar in the north of Iran which located on the southern coast of the Caspian Sea. The results of the research show that differences in ideology and values between Pre and Post Islamic Revolution affected on the Tourism Policy-making in Iran. In the case, the jobs and spatial features related to the tourism have been better and increased, but pollution of the coastal environments and shores have been increased. Also the ecotourism opportunities after the revolution have been more attractive for internal tourists than foreigners.

  4. Agricultural green revolution as a driver of increasing atmospheric CO2 seasonal amplitude

    The atmospheric carbon dioxide (CO2) record displays a prominent seasonal cycle that arises mainly from changes in vegetation growth and the corresponding CO2 uptake during the boreal spring and summer growing seasons and CO2 release during the autumn and winter seasons. The CO2 seasonal amplitude has increased over the past five decades, suggesting an increase in Northern Hemisphere biospheric activity. It has been proposed that vegetation growth may have been stimulated by higher concentrations of CO2 as well as by warming in recent decades, but such mechanisms have been unable to explain the full range and magnitude of the observed increase in CO2 seasonal amplitude. Here we suggest that the intensification of agriculture (the Green Revolution, in which much greater crop yield per unit area was achieved by hybridization, irrigation and fertilization) during the past five decades is a driver of changes in the seasonal characteristics of the global carbon cycle. Our analysis of CO2 data and atmospheric inversions shows a robust 15 per cent long-term increase in CO2 seasonal amplitude from 1961 to 2010, punctuated by large decadal and interannual variations. Using a terrestrial carbon cycle model that takes into account high-yield cultivars, fertilizer use and irrigation, we find that the long-term increase in CO2 seasonal amplitude arises from two major regions: the mid-latitude cropland between 256N and 606N and the high-latitude natural vegetation between 506N and 706 N. The long-term trend of seasonal amplitude increase is 0.311 ± 0.027 percent per year, of which sensitivity experiments attribute 45, 29 and 26 per cent to land-use change, climate variability and change, and increased productivity due to CO2 fertilization, respectively. Vegetation growth was earlier by one to two weeks, as measured by the mid-point of vegetation carbon uptake, and took up 0.5 petagrams more carbon in July, the height of the growing season, during 2001–2010 than in 1961–1970

    2017-03-01

    Full Text Available The punitive turn in Ecuadorian left-wing politics embodies a fundamental contradiction. On the one hand it involved extending social rights and resisting neoliberalism. On the other hand, punitive criminal justice policies intensified. This paper explores what, how, when and why this occurred to explain the complexity of Ecuador’'s punitive turn under a period of twenty-first century socialism. Two eras of national policy will be compared. The first is known as the ‘'long neoliberal night’' (the before; while the second is known as the ‘'Citizens' Revolution’' (the present. The Citizens’' Revolution replaced neoliberal policies with social development, infrastructure, services and programs alongside the more equitable distribution of wealth. In a first moment, it also deployed strategies and actions towards penal moderation. However, since 2010, it has changed dramatically, generating an astonishing punitive turn. The article concludes that law and order policies in Ecuador therefore do not fit Loic Wacquant’'s (2013: 22 description of the ‘'neoliberal penal paradox’'.

    2003-10-01

    This paper profiles the initial phase in the development of a six degree-of-freedom robot, with 1 μm dynamic positioning uncertainty, for the manipulation of x-ray detectors or test specimens at the Advanced Photon Source (APS). While revolute-joint robot manipulators exhibit a smaller footprint along with increased positioning flexibility compared to Cartesian manipulators, commercially available revolute-joint manipulators do not meet our size, positioning, or environmental specifications. Currently, a robot with 20 μm dynamic positioning uncertainty is functioning at the APS for cryogenic crystallography sample pick-and-place operation. Theoretical, computational and experimental procedures are being used to (1) identify and (2) simulate the dynamics of the present robot system using a multibody approach, including the mechanics and control architecture, and eventually to (3) design an improved version with a 1 μm dynamic positioning uncertainty. We expect that the preceding experimental and theoretical techniques will be useful design and analysis tools as multi-degree-of-freedom manipulators become more prevalent on synchrotron beamlines.

    The world is at the dawn of a third industrial revolution, the digital revolution, that brings great changes the world over. Today, computing devices, the Internet, and the World Wide Web are vital technology tools that affect every aspect of everyday life and success. While computing technologies offer enormous benefits, there are equally enormous safety and security risks that have been growing exponentially since they became widely available to the public in 1994. Cybercriminals are increasingly implementing sophisticated and serious hack attacks and breaches upon our nation's government, financial institutions, organizations, communities, and private citizens. There is a great need for computer scientists to carry America's innovation and economic growth forward and for cybersecurity professionals to keep our nation safe from criminal hacking. In this digital age, computer science and cybersecurity are essential foundational ingredients of technological innovation, economic growth, and cybersecurity that span all industries. Yet, America's K-12 education institutions are not teaching the computer science and cybersecurity skills required to produce a technologically-savvy 21st century workforce. Education is the key to preparing students to enter the workforce and, therefore, American K-12 STEM education must be reformed to accommodate the teachings required in the digital age.

    The ongoing digital revolution is no longer limited to the application of apps on the smart phone for daily needs but starts to affect also our professional life in formulation science. The software platform F-CAD (Formulation-Computer Aided Design) of CINCAP can be used to develop and test in silico capsule and tablet formulations. Such an approach allows the pharmaceutical industry to adopt the workflow of the automotive and aircraft industry. Thus, the first prototype of the drug delivery vehicle is prepared virtually by mimicking the composition (particle size distribution of the active drug substance and of the excipients within the tablet) and the process such as direct compression to obtain a defined porosity. The software is based on a cellular automaton (CA) process mimicking the dissolution profile of the capsule or tablet formulation. To take account of the type of dissolution equipment and all SOPs (Standard Operation Procedures) such as a single punch press to manufacture the tablet, a calibration of the F-CAD dissolution profile of the virtual tablet is needed. Thus, the virtual tablet becomes a copy of the real tablet. This statement is valid for all tablets manufactured within the same formulation design space. For this reason, it is important to define already for Clinical Phase I the formulation design space and to work only within this formulation design space consisting of the composition and the processes during all the Clinical Phases. Thus, it is not recommended to start with a simple capsule formulation as service dosage form and to change later to a market ready tablet formulation. The availability of F-CAD is a necessary, but not a sufficient condition to implement the workflow of the automotive and aircraft industry for developing and testing drug delivery vehicles. For a successful implementation of the new workflow, a harmonization of the equipment and the processes between the development and manufacturing departments is a must. In

    Schäfer, M L

    1983-01-01

    The present paper deals with the problematic nature of the phenomenological grasping of the consciousness of the body and its pathological modifications. The reasoning is oriented by the doctrine of Husserl of the so-called sentiments as the fundamentals of the experience of the own body. This basic approach does not only seem to be basically for a psychology of the consciousness of the body, but also to give the theoretical-conceptual structure for a great number of psychopathological modifications. Subsequent to a criticism of the conventional use of the term 'hallucination of the body' we attempt to chart elements of a scheme of the abnormal consciousness of the body.

The author notes that during the First Russian Revolution (1905–1907 peasants in rural communities, as, for instance, those within the Black Sea Governorate’s Sochi Okrug, were in point of fact left to themselves. Having found themselves alone with members of the social-democratic party, the rural communities had to decide: whether to buy into revolutionary propaganda or sabotage anti-government activity.

  13. Thailand's reproductive revolution.

    1987-01-01

    Thailand has achieved a remarkable population revolution in the past 15 years, resulting in a fertility decline of 44%, the 3rd greatest decline of the major developing countries. Thailand is quite distinct from either China or South Korea, the leaders in fertility decline. It has neither China's authoritarian power system to enforce population control nor the highly developed, Westernized outlook of South Korea. Instead it achieved its astounding fertility drop through a noncoercive family planning program operating within a context of rapid social change and a cultural setting. Thailand's drop in population growth has touched almost all segments of Thai society. The preferred number of children among couples married less than 5 years has dropped in both rural and urban families at almost exactly the same rate, from about 3.2 in 1969 to 2.3 in 1984. Religious groups represent the only substantial difference in family size preference; Moslem women married less than 5 years stated a desired average of 3.1 children versus 2.3 for Buddhist women. The direct case of the fertility drop is a national increase in contraceptive use. In 1984, 65% of Thai women reported using contraception. The Thai population, however, was ripe for using contraception when it became available due to 1) mass media creating a desire for consumer goods, 2) the increased costs of education to parents, 3) the willingness of parents to trade off "parent repayment" from many children for a few quality children, 4) couples' autonomy in fertility decision making, 5) the high status of women in Thailand, and 6) the fact that Buddhism poses no barriers to contraception. Current trends show no immediate sign of change.

    Full Text Available Otpor is discussed in the text as a complex and contradictory new type of social movement, whose members attempted to contribute to the tradition of enlightened reform of social and political life in Serbia, simultaneously in a highly pragmatic and in a creative, possibly even irresponsible manner. After the introduction, analyzed are popular and media narratives on the characteristics of the movement, dilemmas concerning the founding of the movement and meaning of its key symbols, and the Faustian question of goals and consequences of foreign, in particular American influences. Following is a discussion of strategic (non-violent revolution, calculated victimization and tactical (black campaigns, get-out-the-vote campaign roles of Otpor in the coordinated project of ousting Milosevic. Otpor’s role is then re-interpreted in the frame of the ‘electoral revolution’, developed by Valerie Bunce, Sharon Wolchik and Michael McFoul. An assessment of the transformation of Otpor from an active social movement into an exportable blueprint for non-violent political revolutions is offered in lieu of a conclusion.

    Full Text Available http://dx.doi.org/10.5007/1677-2954.2014v13n2p303It is the sole topic of conversation throughout Europe. An economic crisis with an underlying crisis of values is devastating everything, while politics has nothing to say. An attempt was made to base the European Unión on a single currency, and the resulting traders’ Europeprevented the desired political project from bearing fruit. Instead of comparing different legal systems before creating a constitution for citizens, we have seen the birth of a new idolatry that is connected with a perverse fatalism. Only macroeconomic figures are considered to be important, while citizens have to suffer because of the actions of a few unscrupulous people who worship profit as well as having legalised usury.Given this situation it is necessary to take all types of precaution, and that is why it is a good idea to see what classical authors have to say. The Enlightenment seems to be a failed project that urgently needs to be restarted. It may be enormously useful to re-read Rousseau, as Cassirer did during the rise of Nazism so that it could be fought on the basis of the history of ideas. His discourse on inequality could not be more relevant now. And the same consideration applies to the genealogical study of the French revolution by Tocqueville. That was the revolution par excellence which Kant described as a symbol of the moral progress of mankind.

    environment warmed by a CH4 greenhouse (3) should occur fairly rapidly, within ˜ 10 My. The trigger requires both the evolution of cyanobacteria and sufficiently high nutrient (mainly P) fluxes to allow O2 production to overwhelm reductant fluxes. P flux into the oceans in glaciated worlds correlates with increased continental weathering during glacial intervals (4). Thus, were cyanobacteria present during the Huronian glaciations, which predate 2.22 Ga (5), these glaciations should have triggered the oxygenation event. Instead, the oxygenation event seems to correlate with the Makganyene glaciation, at 2.22 Ga (6). The appearance of red beds in the Upper Timeball Hill formation directly underlying the Makganyene diamictite supports this interpretation. As would be expected from a glaciation associated with the destruction of a CH4 greenhouse, paleomagnetic data indicate the Makganyene glaciation was a global Snowball event (7). Cyanobacteria appear to have evolved in the short interval between the Huronian glaciations and the Makganyene glaciation. The lengthy delay between the earliest life on Earth and the appearance of cyanobacteria suggests that the oxygenic revolution was a fairly low probability event; planets with oxygenic biospheres may be quite rare. 1.

    Teaching and research in anatomy is mainly based on cadaveric dissection. Unclaimed bodies is no more the origin of cadavers, but body donation programs. The dissection is an important part in the anatomical curses of medical students and for anatomical research and special courses devoted to the surgeons. A body donation center was created in Paris in 1953 with the purpose of obtaining bodies for dissection. Donation is a clear will made by people free and informed. Donation is most often by altruism, conferrins life on another. Body donation is regulated by various act or reglementar text according to each country. One of the problem with the body gift is biological hazard, specially in research and clinical courses, but the rule is to consider unembalmed material as contaminated and to use all precautions with barrier for blood and bodily fluid. Body donation is one of the modern expression of solidarity.

    Full Text Available This article addresses a question relevant to those interested in the achievement of greater sustainability: What are some of the ways that major societal transformations come about? Firstly, four key mechanisms are identified in the article. Then, I go on to focus on one of these, which has a prominent place in the sustainability revolution that it is argued is now taking place. The question of what are characteristic features of the sustainability revolution is addressed. The ongoing transformations are largely piecemeal, incremental, diffuse—in earlier writings referred to as “organic”. Organic is a more encompassing notion than “grassroots”, since the innovation and transformation processes may be launched and developed at multiple levels by collective agents that in some cases are very large and would not be understood as “grassroots” actors. The article argues that the sustainability revolution shares some features, in particular its organic character, with the early industrial revolution. It concludes by addressing the question of what are the similarities and differences between the sustainability and industrial revolutions.

    In his unfinished writings about the French Revolution and Napoleon, Tocqueville analyzed the tension between liberty and equality and the political dynamics of the Revolution.During the liberal revolution from 1787 to 1789 which was the first period of the French Revolution, the class struggle provoked by the radical idea of democratic liberty gradually defeated the ideas of the aristocratic and elitist liberty.The weakening of the royal power and its wrong decisions aggravated the class struggle and strengthened the revolutionary ideology.The popular violence which pushed the radicalization of the Revolution created divisions in the camp of revolution which with the struggle for power brought the reign of Terror.During the late period of the French Revolution,the French people grew disgusted by the instability caused by revolution while enjoying the equality and advantages brought about by the Revolution.As a result,Napoleon Bonaparte who had assumed the equality of the Revolution and abandoned its pursuit of liberty was supported by the French people.Besides the analysis of the revolutionary process and dynamics, Tocqueville’s writings on the French Revolution confirmed his thesis in The Old Regime and the Revolution about the continuity between the Old Regime, the French Revolution and Napoleonic rule.French revolutionaries unwittingly inherited the political culture of Statism and the administrative centralization which dominated the Old Regime,while at the same time they destroyed aristocratic and feudal elements that could resist the absolute power.The French people accomplished the Revolution with the aid of the Old Regime and constructed a state and a centralization that was much more powerful than those autocrats during pre-1789 French history.%托克维尔在关于法国大革命与拿破仑的未完成著述中讨论了大革命中自由和平等的张力以及革命的政治动力。在作为大革命第一阶段的1787-1789年的自由革命中,

We use singular perturbations approach to find the rigorous asymptotic expression for the local particles concentration as an expansion in the ratio of the characteristic transversal and longitudinal diffusion relaxation times. The corresponding leading-term approximation is a generalization of well-known Fick-Jacobs approximation. This result allowed us to delineate the conditions on temporal and spatial scales under which the Fick-Jacobs approximation is valid. A striking analogy between solution of our problem and the method of inner-outer expansions for low Knudsen numbers gas kinetic theory is established. With the aid of this analogy we clarify the physical and mathematical meaning of the obtained results.

    Full Text Available 1962 marked an important point in intellectual history not only for historians, philosophers, sociologists and scientists but also for educated laymen. After a long and productive decade Thomas Kuhn published his “Structure of Scientific Revolutions” as Volume 2 Issue 2 of the “International Encyclopedia of Unified Science”, edited (after the death of Otto Neurath by Rudolf Carnap and Charles Morris. 2012 marked another important date—it was the 50th anniversary of Structure’s first edition. The many conferences, workshops and presentations were documented in special issues and collections; one of them is Kuhn’s “Structure of Scientific Revolutions – 50 Years On”, edited by William J. Devlin and Alisa Bokulich. The review aims to shed light on the collections relevance for current interdisciplinary studies.

  14. Hacking the quantum revolution: 1925-1975

    Schweber, Silvan S.

    2015-01-01

    I argue that the quantum revolution should be seen as an Ian Hacking type of scientific revolution: a profound, longue durée, multidisciplinary process of transforming our understanding of physical nature, with deep-rooted social components from the start. The "revolution" exhibits a characteristic style of reasoning - the hierarchization of physical nature - and developed and uses a specific language - quantum field theory (QFT). It is by virtue of that language that the quantum theory has achieved some of its deepest insights into the description of the dynamics of the physical world. However, the meaning of what a quantum field theory is and what it describes has deeply altered, and one now speaks of "effective" quantum field theories. Interpreting all present day quantum field theories as but "effective" field theories sheds additional light on Phillip Anderson's assertion that "More is different". This important element is addressed in the last part of the paper.

    ``A problem with defining force as rate of change of linear momentum'': Let us consider a body of mass m, moving with velocity u initially, in the next time interval it is acted by a force in the direction of motion, and at instant t + its mass is M and velocity v. F .t =Mv-mu or,v = m/M.u +F/M.t or,v =B.u +A.t where A =F/M,B =m/M. So other eqn of motion are: dS =vdt or dS =(B.u +A.t)dt or S =B.u.t +A/2.t2 Andv2 =B2 u2 +2A .B .u .t +A2 t2 or,v2 =B2 u2 +2A.S However, defining acceleration as rate of change of velocity, we have established an identity v =u +a.t which is independent of choice of v, u. M>>m, B is very small, product B.u or its higher power always tend to be negligible, even in cases when u is finitely large.In cases v ->c,F,M -> ∞ , thus A becomes indeterminate.There is inconvenience as A, B are not predetermined and are functions of u, v and thus the definition goes in circle. Hence we conclude, our hypothesis that force =rate of change of linear momentum is not sufficient; we would now find trial solutions to define force in most convenient way.

    1980-01-01

    A recently reported Parabolized Navier-Stokes code has been employed to compute the supersonic flow field about spinning cone, ogive-cylinder, and boattailed bodies of revolution at moderate incidence. The computations were performed for flow conditions where extensive measurements for wall pressure, boundary layer velocity profiles and Magnus force had been obtained. Comparisons between the computational results and experiment indicate excellent agreement for angles of attack up to six degrees. The comparisons for Magnus effects show that the code accurately predicts the effects of body shape and Mach number for the selected models for Mach numbers in the range of 2-4.

    Full Text Available This paper is an attempt to provide a certain “second reading” of those commonplaces which imply that a particular, personal interest always lies behind the mask of objectivity, necessity and truth. As a paradigmatic example of this kind of structure that implies “hidden truths”, here will be taken that of a revolution, whether it is a fascist, a liberal-democratic or a communist revolution. By reexamining how this motif of “truth-behind-the-mask” figures in those regimes, we will try to say something about each of them, and also about the specific kind of subject that is produced under them.

The ""astronomical revolution"" was accomplished in three stages, each linked with the work of one man. With Copernicus, the sun became the centre of the universe. With Kepler, celestial dynamics replaced the kinematics of circles and spheres used by Copernicus. With Borelli the unification of celestial and terrestrial physics was completed by abandonment of the circle in favour the straight line to inf

    Axial body lateropulsion, a phenomenon where the body is pulled toward the side of the lesion, with tendency of falling down, is the well-known transient feature of lateral medullary syndrome. In some cases, axial body lateropulsion occurs without vestibular and cerebellar symptoms (isolated body lateropulsion:[iBL]). Patients with iBL have a lesion located in the spinocerebellar tract, descending lateral vestibulospinal tract, vestibulo-thalamic pathway, dentatorubrothalamic pathway, or thalamocortical fascicle. This review deals with the anatomic basis and clinical significance of iBL.

    2013-03-13

    Societies before the Industrial Revolution were dependent on the annual cycle of plant photosynthesis for both heat and mechanical energy. The quantity of energy available each year was therefore limited, and economic growth was necessarily constrained. In the Industrial Revolution, energy usage increased massively and output rose accordingly. The energy source continued to be plant photosynthesis, but accumulated over a geological age in the form of coal. This poses a problem for the future. Fossil fuels are a depleting stock, whereas in pre-industrial time the energy source, though limited, was renewed each year.

O cinema foi apresentado pela primeira vez no país em uma sessão dedicada a Porfirio Díaz. Percebendo seu potencial propagandístico, o ditador logo se converteria na primeira grande estrela do cinema mexicano. O cinema forjava-se como "documento histórico" stricto sensu, num registro da verdade inquestionável. A Revolução redefiniu seu papel, registrando a ebulição pela qual passava a sociedade em documentários que se distanciavam do mero aspecto da curiosidade espetacular para atingir uma verdadeira presença do realizador junto ao cenário político nacional. O desdobramento da Revolução, com a superação da fase insurrecional, e o processo de domesticação do discurso revolucionário no âmbito oficial acabaram por esvaziar o teor de contestação das imagens documentais. A imagem do corpo de Zapata assassinado, que circulou pelo território nacional, é um emblema deste projeto.This article shows the connections between cinema and history in the two first decades in XX century in Mexico.

    From 1911 to 1913, in big streets and small lanes, in famous parks and thriving stores, and in tea houses and grand restaurants located in such cities as Shanghai, Nanjing, Beijing and Wuchang, numerous business opportunities were bom out of the Revolution of 1911. By using the political giants and military leaders around Shanghai, business firms skillfully dealt with the difficulties of the continually changing political situation and managed to keep their businesses afloat, succeeding in their response to the consumption demands of the public. It can be argued that the Revolution of 1911 played a distinct role in the development of businesses in Shanghai during that time.%1911-1913年间在上海、南京、北京、武昌等城市的大街小巷、名园旺铺、茶馆酒楼,有许多因辛亥革命而起,或与辛亥革命相关的生意.这些生意对各色人等都有着大小不一的影响和联系.从以上海为中心的伟人将帅在生意中所产生的影响、商家在政治变局中应对困难的努力、继续开展生意的手段以及消费大众对生意的呼应,可以发现城市与辛亥革命通过生意在互动影响.

    In the present developed world, all of us are flooded with electromagnetic radiations (EMR) emanating from generation and transmission of electricity, domestic appliances and industrial equipments, to telecommunications and broadcasting. We have been exposed to EMR for last many decades; however their recent steady increase from artificial sources has been reported as millions of antennas and satellites irradiate the global population round the clock, year round. Needless to say, these are so integral to modern life that interaction with them on a daily basis is seemingly inevitable; hence, the EMR exposure load has increased to a point where their health effects are becoming a major concern. Delicate and sensitive electrical system of human body is affected by consistent penetration of electromagnetic frequencies causing DNA breakages and chromosomal aberrations. Technological innovations came with Pandora's Box of hazardous consequences including neurodegenerative disorders, hearing disabilities, diabetes, congenital abnormalities, infertility, cardiovascular diseases and cancer to name few, all on a sharp rise. Electromagnetic non-ionizing radiations pose considerable health threat with prolonged exposure. Mobile phones are usually held near to the brain and manifest progressive structural or functional alterations in neurons leading to neurodegenerative diseases and neuronal death. This has provoked awareness among both the general public and scientific community and international bodies acknowledge that further systematic research is needed. The aim of the present review was to have an insight in whether and how cumulative electro-magnetic field exposure is a risk factor for neurodegenerative disorders.

  20. [Pierre Bourdieu: sociology as a "symbolic revolution"].

    Science.gov (United States)

    Suaud, Charles

    2014-03-01

    The article combines two objectives: understand the genesis and development of the sociology of Bourdieu in connection with his social and intellectual positioning. The sociology of Bourdieu is a theory of Action which reconciles the double requirement of objectification and taking account of the practical logic bound by social agents. From the character both objective and subjective of social space, he analyzes how different institutions (firstly School) are doing that mental structures match the objective structures of society. By making acceptable reality and registering it in the body, these instances contribute to reproduce social divisions and participate in the work of domination. Gradually, Bourdieu develops a general theory about Power, which leads to a sociology of State. But he refuses any sociological fatalism. Because he perceived homologies between the sociologist and the artist facing the social order, each in their own way, he devoted two researches to Flaubert and Manet, seized in the same enterprise of aesthetic subversion he described as a 'symbolic revolution'. In many aspects, the sociology of Bourdieu opens ways of looking for an objectification of caregivers and their practices.

    We study the motion of a secondary celestial body under the influence of the corrected gravitational force of a primary. We study the effect of quantum and relativistic corrections to the gravitational potential of a primary body acting on the orbiting body. More specifically, two equations are derived to approximate the perigee/perihelion/periastron time rate of change and its total variation over one revolution (i.e., the difference between the anomalistic period and the Keplerian period) under the influence of the quantum as well as post- Newtonian accelerations. Numerical results have been obtained for the artificial Earth satellite Molnya, Mercury, and, finally, the for the HW Vir c, planetary companion.

    Gupta, Anamika; Mishra, Gaurav; Bhutani, Hemant; Hoshing, Chetan; Bhalla, Ashish

    2016-01-01

    Objectives: With the growth of forensic odontology, dental records have become an essential source of information, especially for medicolegal cases in general practice. It is mandated by the law that every dentist must keep some kind of records for every patient they treat. After the death of an individual, remnants of teeth are usually damaged at the last among all body parts. Dental records assist in personal identification in cases of mass disasters, criminal investigations, and medicolegal issues. However, in India, rules for maintaining dental records are not very strictly followed. Thus, the aim of this study was to evaluate the knowledge regarding the maintenance of dental records among dentists in Punjab and Uttar Pradesh. Materials and Methods: Data collection was performed via a questionnaire. The study population responded to the questions pertaining to knowledge regarding forensic odontology methods and the mode of maintaining dental records in their regular practice through a personal interview. A descriptive analysis was carried out for the data. The data were summarized and analyzed using the statistical software Statistical Package for the Social Sciences (SPSS) version 18.0. Results: A very low percentage (22%) of the dentists were seen to be maintaining records on a regular basis. Seventy-eight percent of the dentists were not maintaining any records. Conclusion: This study clearly indicates that the dentists in Punjab and Uttar Pradesh need to be properly trained for any kind of forensic and medicolegal needs. PMID:27583219

The well-renowned mission Rosetta set a milestone in space science history when it successfully lowered its mini-lab Philae onto the surface of Comet 67P/Churyumov-Gerasimenko in November 2014. Knowledge of the gravitational field of a small body, e.g. a comet or asteroid, is crucial in order to study a spacecraft's motion in its environment and to infer geophysical properties. Traditionally, the gravitational field of a body is modeled by means of spherical harmonics. For bodies of near-spherical shape (such as the Earth), this is an adequate method, because the reference figure, i.e. a sphere, snugly fits the body. For irregularly shaped bodies, however, the adoption of spherical harmonics might be a sub-optimal choice. As an alternative, oblate or prolate spheroidal harmonics (OH or PH, reference figure is an ellipsoid of revolution) or ellipsoidal harmonics (EH, reference figure is a tri-axial ellipsoid) should be considered. The latter will in general be the best choice in terms of aptness of the reference figure. The downside of EH, however, lies in the considerably increased (numerical) complexity of the computation of the base functions, i.e., the Lamé functions of the first and second kind. OH or PH represent a promising path down the middle. Elongated bodies (such as Asteroid 433 Eros) are often similarly well approximated by a prolate spheroid as by the corresponding tri-axial ellipsoid. Contracted bodies, on the other hand, can be described accordingly well by means of an oblate spheroid. We compare the SH, OH, PH and EH gravitational field parameterizations for different celestial bodies, including Rosetta's target comet 67P. The tasks are as follows: Based on the polyhedral representation of a body's shape model, the gravitational potential and acceleration vector is computed for evenly or irregularly distributed points inside or outside

    Aerodynamic interference effects were studied for two slender, streamlined bodies of revolution at Mach 2.7. A wind tunnel investigation produced force and moment data and measurements of pressure distributions on the bodies. As these bodies remained parallel with each other and with the freestream flow, their relative lateral and longitudinal spacing were varied. Results of theoretical methods were used in the analysis of results. The interference effects between the two bodies yielded less total drag than a single body of equal total volume and the same length.

    Full Text Available In article the question of a role of parish clergy which the activity, behavior, moral shape formed public ideas of the Russian church in general is investigated. It is noted that in conditions of the first Russian revolution position of parsons as spiritual pastors, was rather difficult. They should have read sermons, to speak with the parishioners, but they didn't know what assessment to give to the taking place events. And the many thousands clergy on the whole was silent about revolutionaries since the majority itself didn't understand what occurs in the country. However, a part of priests, understanding all complexity of a situation, tried to offer solutions of a problem of moral education of parishioners and counteraction to revolutionary promotion. In their opinion, it was necessary to expand scales of the traditional oral sermon; to discuss the main events which are taking place in the country with parishioners; to improve the education; to issue newspapers, etc. But in general, the ROC couldn't become the political educator of the parishioners.

    Bläsing, Bettina; Schack, Thomas; Brugger, Peter

    2010-05-01

    We investigated mental representations of body parts and body-related activities in two subjects with congenitally absent limbs (one with, the other without phantom sensations), a wheelchair sports group of paraplegic participants, and two groups of participants with intact limbs. To analyse mental representation structures, we applied Structure Dimensional Analysis. Verbal labels indicating body parts and related activities were presented in randomized lists that had to be sorted according to a hierarchical splitting paradigm. Participants were required to group the items according to whether or not they were considered related, based on their own body perception. Results of the groups of physically intact and paraplegic participants revealed separate clusters for the lower body, upper body, fingers and head. The participant with congenital phantom limbs also showed a clear separation between upper and lower body (but not between fingers and hands). In the participant without phantom sensations of the absent arms, no such modularity emerged, but the specific practice of his right foot in communication and daily routines was reflected. Sorting verbal labels of body parts and activities appears a useful method to assess body representation in individuals with special body anatomy or function and leads to conclusions largely compatible with other assessment procedures.

  16. Dissent, revolution and liberty beyond Earth

    CERN Document Server

    2016-01-01

    This volume provides an in-depth discussion on the central question – how can people express and survive dissent and disagreement in confined habitats in space? The discussion is an important one because it could be that the systems of inter-dependence required to survive in space are so strong that dissent becomes impossible. John Locke originally said that people have a right to use revolution to overthrow a despotic regime. But if revolution causes violence and damage that causes depressurisation with the risk of killing many people, is it even permissible to have a revolution? How then are people to express their liberty or dissatisfaction with their rulers? The emergence of structures of dissent and disagreement is an essential part of the construction of a framework of liberty in space (revolution is just the extreme example) and thus the topic deserves in-depth and immediate attention. Even today, the way in which we assemble organisations and corporations for the government and private exploration o...

  1. Analytical continuation in physical geodesy constructed by means of tools and formulas related to an ellipsoid of revolution

    Science.gov (United States)

    Holota, Petr; Nesvadba, Otakar

    2014-05-01

    In physical geodesy mathematical tools applied for solving problems of potential theory are often essentially associated with the concept of the so-called spherical approximation (interpreted as a mapping). The same holds true for the method of analytical (harmonic) continuation which is frequently considered as a means suitable for converting the ground gravity anomalies or disturbances to corresponding values on the level surface that is close to the original boundary. In the development and implementation of this technique the key role has the representation of a harmonic function by means of the famous Poisson's formula and the construction of a radial derivative operator on the basis of this formula. In this contribution an attempt is made to avoid spherical approximation mentioned above and to develop mathematical tools that allow implementation of the concept of analytical continuation also in a more general case, in particular for converting the ground gravity anomalies or disturbances to corresponding values on the surface of an oblate ellipsoid of revolution. The respective integral kernels are constructed with the aid of series of ellipsoidal harmonics and their summation, but also the mathematical nature of the boundary date is discussed in more details.

    2010-01-01

    Herminia Franco-Espinoza was the first woman to receive a medical degree in the "Colegio del Estado de Puebla", Mexico. She was born in Chietla, Puebla, in 1891, and was daughter of Professor Felipe Franco-Pacheco and Zeferina Espinoza-Nape. Herminia concluded her professional studies in 1915 and graduated in 1917. During the 1910 attack to the house of the Serdán family in Puebla, she provided medical care to the first injured while she was a voluntary practitioner at the Hospital de San Pedro. She participated in the signing of the anti-reelectionist letter of the group "Luz y Progreso", headed by Aquiles Serdán. Thereafter, she moved to Mexico City and established at Plaza de la Constitución 37, where she opened a medical office. In 1920 she undertook a course on gynecology and obstetrics and child welfare at the National University of Mexico. In 1937 she traveled to Paris to undertake a course on Gynecology and Obstetrics and Pediatrics at L'Hôpital Broca, L'Hôpital Baudelóc and L'Hôpital des Enfants Malades. She retired in 1965 when she completed 50 years of professional practice. On 1970 she was recognized as a Veteran of the Mexican Revolution. Dr. Franco was part of the group of women who at the beginning of the last century pioneered in Mexico women's participation in mexican medicine.

The underpinning of this study is based on Social Comparison Theory with two additional variables (religiosity and self-esteem for understanding understand consumer attitude towards body image. A self-administered questionnaire was used. 193 persons responded at mall intercepts. The Conceptual framework was empirically tested through SEM. A positive relationship between exposure to media and body image was found while negative influence was found between self-esteem and body image. No relationship was found between religiosity and body image. The results showed mixed outcomes as compared to past studies. The scope of this study is limited to one city only and hence the finding could not be generalized. Future researcher may use a larger sample drawn throughout Pakistan, and by examining whether body image perception varies ethnically, age and gender. Media exposure is affecting the traditional norms and values of Pakistan culture and body image. The obsessions of the media and thin body image have to be controlled and this requires policy changes. Corporate sector might take initiative by not selecting ultra-thin models. They might also sponsors public service messages showing ill effects of being ultra-thin, and showing that the ultra-thin models are not real but is results of artworks and camera angles. Social Comparison Theory with two addition variable religiosity and self-esteem has been successfully extended/empirically tested in the domain of Pakistan culture.

  5. The Darwinian revolution: rethinking its meaning and significance.

    Ruse, Michael

    2009-06-16

    The Darwinian revolution is generally taken to be one of the key events in the history of Western science. In recent years, however, the very notion of a scientific revolution has come under attack, and in the specific case of Charles Darwin and his Origin of Species there are serious questions about the nature of the change (if there was such) and the specifically Darwinian input. This article considers these issues by addressing these questions: Was there a Darwinian revolution? That is, was there a revolution at all? Was there a Darwinian revolution? That is, what was the specific contribution of Charles Darwin? Was there a Darwinian revolution? That is, what was the conceptual nature of what occurred on and around the publication of the Origin? I argue that there was a major change, both scientifically and in a broader metaphysical sense; that Charles Darwin was the major player in the change, although one must qualify the nature and the extent of the change, looking particularly at things in a broader historical context than just as an immediate event; and that the revolution was complex and we need the insights of rather different philosophies of scientific change to capture the whole phenomenon. In some respects, indeed, the process of analysis is still ongoing and unresolved.

    Full Text Available This paper traces successful and unsuccessful attempts to shape the meanings of the video game Dance Dance Revolution, specifically with reference to what "dancing" means in this context, as the game moves between various interested parties - game developers, players, Internet forum participants, and other media producers. Drawing on Actor-Network Theory and the network analyses of Manuel Castells, the paper reconstructs the forces shaping players' stylistic decisions through an analysis of dance game machines and software, and of a single forum thread on DDRFreak.com, a major website in the dance game community. The paper asks who decides how DDR players dance and at what times? Are the decisions about play made in the development meeting, the arcade, competitions, online or around the home console? Globally, how do some regions or groups emerge as experts or leaders in play style? Analysis indicates that within the United States, Californian players from major cities dominate discussion, supported by the global flows of people, resources, and capital through the state. The dominant players support their stated norms for play through recourse to mainstream conceptions of masculinity, rap music and associated styles of dance.

  7. The changing face of terrorism in the 21st century: the communications revolution and the virtual community of hatred.

    Post, Jerrold M; McGinnis, Cody; Moody, Kristen

    2014-01-01

    There are no psychological characteristics or psychopathology separating terrorists from the general population. Rather, it is group dynamics, with a particular emphasis on collective identity, that helps to explain terrorist psychology. Just as there is a diverse spectrum of kinds of terrorism, so too is there a spectrum of terrorist psychologies. Some terrorists, those in nationalist-separatist groups, such as Fatah and the IRA, are continuing with the mission of their parents who are dissident to the regime. The opposite generational provenance is seen among social-revolutionary terrorists, such as the Weather Underground and the Red Army Faction in Germany, who are rebelling against their parents' generation, which is loyal to the regime. Four waves of terrorism can be distinguished: the "anarchist wave"; the "anti-colonial wave" (nationalist-separatist), with minority groups seeking to be liberated from their colonial masters or from the majority in their country; the "new left" wave (social-revolutionary); and now the "religious" wave. With the communications revolution, a new phenomenon is emerging which may presage a fifth wave: lone wolf terrorists who through the Internet are radicalized and feel they belong to the virtual community of hatred. A typology of lone wolf terrorism is proposed.

    Full Text Available The present study analyses factors associated with the propensity for piercing and tattooing among adolescents, from a survey conducted in 2007 in high schools in the Veneto Region (Northeast Italy. After some descriptive analyses, multinomial logistic regression models were applied to identify what predicts the practice of, interest in, or indifference to piercing and tattooing. Results show gender differences in the approach to body modification: For girls, body art is considered a mainstream activity involving younger cohorts; piercing and tattooing become a way of increasing their own body satisfaction. For boys, factors connected with the propensity for these practices are a low cultural background and the importance given to physical appearance. For both boys and girls, a significant aspect in defining attitudes toward body art practices is the values system: Values such as enjoyment, beauty, and youth, are found to be closely connected with a high propensity for these practices.

    Full Text Available Focusing on a study of Taiwan’s United News Daily archive and the shifting discourses of the Green Revolution and the organic food movement, the project analyzes the narrative frameworks produced on the apple snail (Pomacea canaliculata in Taiwan. Apple snail has become invasive to many East Asian countries since the 1980s; it is considered among the world’s 100 most invasive species. During the era of the Green Revolution, the economy of killing the apple snail with pesticide was generated by a narrative of how greedy merchants imported invasive apple snail and led to the systematic disruption of Taiwan’s ecology. The paper explores how the organic food movement responded to and was shaped by such a narrative of innocence lost, and emphasizes the importance of going beyond the hyper-real narratives of irreparable ecological destructions by recognizing sites of memories left behind by global capital flow.

    Pierre-François Nicolas, was born in Saint-Mihiel in 1743, studied in this town and in St-Nicolas-de-Port near Nancy. At first he has been a military apothecary during the "Guerre de Sept-Ans". Then he studied pharmacy in Nancy and was received in 1768 at the "Maîtrise de pharmacie". With the physician Henri Michel du Tennatar, he created a teaching of chemistry for medicine students and became the professor of chemistry of the Faculty of Medicine in 1781. During these years, he published some research results about hydrology, distillery, biochemistry (phosphorus in bone), toxicology, dyeing... At the end of 1783, he succeeded in the realization of a balloon and he played an important part in Nancy during the French Revolution. Professor at the "Ecole de médecine" in Strasbourg for some weeks, then in Nancy at the "Ecole centrale" and at the "Société de santé", he left Nancy towards the mid-1798. Staying in Paris for two or three years he probably worked with Fourcroy and perhaps Chaptal and Berthollet. In the early years of the nineteenth century he was appointed professor in the "Ecole centrale" du Calvados" and some years after at the "Faculté des sciences" in Caen. His latest significant work with Gueudeville was devoted to the detection of sugar in the urine of diabetic patients. Retired in 1811 Pierre-François Nicolas died in Caen in 1816.

  17. The Industrial Revolution and Birth of the Anti-Mercantilist Idea:Epistemic Communities and Global Leadership

    Directory of Open Access Journals (Sweden)

    Daniel J. Whiteneck

    2015-08-01

    Full Text Available This paper seeks to offer a new perspective on the linkage between global leadership and the role of epistemic communities in international relations. The issue of bilateral trade liberalization between Great Britain and its trading partners rose to prominence on the global agenda in the 1700s by the efforts of British political economists and merchants. These efforts were prompted by changes in economic relations brought about by the Industrial Revolution and its impact on the mercantile system. While this group was small in number and its interactions rudimentary by 20th Century standards, it nonetheless met the qualifications specified by many scholars. It is further argued that such communities are linked to the exercise of global leadership in the long cycle model's phases of agenda setting and coalition building. They arc started and based in the global leader, and arc nurtured by the relatively open social and political structures of that leader. Evidence supporting this argument strengthens the long cycle model's explanatorypower with regard to agenda setting, coalition creation, and the role of innovative solutions to global problems, and makes preeminence in knowledge -based communities another dimension of global leadership.

    The importance of commensal microbes for human health is increasingly recognized, yet the impacts of evolutionary changes in human diet and culture on commensal microbiota remain almost unknown. Two of the greatest dietary shifts in human evolution involved the adoption of carbohydrate-rich Neolithic (farming) diets (beginning ∼10,000 years before the present) and the more recent advent of industrially processed flour and sugar (in ∼1850). Here, we show that calcified dental plaque (dental calculus) on ancient teeth preserves a detailed genetic record throughout this period. Data from 34 early European skeletons indicate that the transition from hunter-gatherer to farming shifted the oral microbial community to a disease-associated configuration. The composition of oral microbiota remained unexpectedly constant between Neolithic and medieval times, after which (the now ubiquitous) cariogenic bacteria became dominant, apparently during the Industrial Revolution. Modern oral microbiotic ecosystems are markedly less diverse than historic populations, which might be contributing to chronic oral (and other) disease in postindustrial lifestyles.

" Therefore, the basis of Marx's metaphysics of the modem philos- ophy of criticism of modem rationalism is the philosophy of the revolutionary path appearance of reality, and its philosophy of revolution is its radical critique of modern philosophy conclusions. In other words, the modern basis of modem rationalism and its metaphysical philosophy and Marx's philosophical revolution is not by chance among the external implications, but integral to inter-related with.%现代性诸矛盾现象背后有其深刻的形而上学基础,这就是近代理性主义哲学。对现代性批判的彻底性要求导致马克思对现代性的形而上学基础近代理性主义哲学的两大根基——抽象本体和抽象的人进行批判,颠覆其形而上学的思维方式,进而走向哲学革命,最终创立以实践作为其哲学根本观点的"新唯物主义"。因此,马克思对近代理性主义哲学的批判是其哲学革命出场的现实路径,而其哲学革命则是其现代性批判彻底化的哲学结论。

    Ore dumps are heterogeneous bodies with anisotropic seepage characteristics because of the ore segregation.In an indoor experiment, a dump was constructed with three strata, where the horizontal and vertical seepage experiments were carried out.Horizontals flow are regarded as phreatic plan flows without penetration.Its seepage law satifies the Dupuit equation.With parallel lay seepage model, the equivalent seepage coefficient in the horizontal flow was obtained and was equivalent to the weighted mean of the seepage coefficient of each stratum.An unsaturated flow appeared in the vertical experiment, with a hydraulic gradient of 1.The vertical flow was equivalent to the seepage model that moved in vertical bedding; its equivalent seepage coefficient depended on the stratum with the minimum seepage coefficient.That the experiment showed clear anisotropy in a heterogeneous body was obvious with an anisotropic coefficient between 63 and 155, which is 25 to 100 times larger than that of a homogeneous body.

He goes out into the garden at Croisset: lime trees, then poplars, then the Seine. An outbuilding on a bank beside some water. He’s finished Part One of Madame Bovary.That Sunday, he would write Louise Colet how at dawn on Friday he’d felt strong, serene, blest in sense and in purpose. The dawn wind does him good. He has a tired fat handsome face, a calm fat handsome face. He loves writing. He loves the world.“Deprived of a party, country, house, personal life, etc., he made writing his only reason to live, and it grips one’s heart how seriously he takes the written world.” These words of Pasolini’s pertain to Gombrowicz. But they might just as well be applied to Flaubert, and one’s heart would not be gripped any less, maybe more. For, if Flaubert had a personal life (as Gombrowicz did after all, but then Pasolini always goes very fast, he pretended not to have one; just as he pretended to have no house, country, freedom, mother named Caroline, orphaned niece also named Caroline, Seine at the end of the path, rolling on before his eyes, sharecroppers’ hillside groves, heaps of disciples and flatterers, well-meaning interns hard at work on his behalf in the corridors of Paris journals and salons: all things Gombrowicz truly did not have, that he, Flaubert, had. Flaubert pretended to have none of all that, that which he had, and for him this pretension became real; he patched together a mask which comprised his skin, and with which he wrote his books; skin and mask had been so well glued that when he wished to retire it, he found nothing more in his hand than an indissoluble mixture of flesh and cardboard under the thick clown moustache. Perhaps it wasn’t truly the clown that he played so much as the monk, and not just to the stands, but in his own eyes and to himself: he was

  4. Sexual revolution in China: implications for Chinese women and society.

    China is undergoing rapid changes in sexual mores due to several reasons such as decreasing control of the state over private lives of individuals, globalization of its economy, and some policies initiated by the state. There is increased acceptance of premarital sex and extramarital sex in China, especially among youth. In historically conservative China, influenced by Confucian ideals of patriarchal dominance for centuries, the sexual freedom currently enjoyed by many is unprecedented. This has impacted women's status and sexual lives in several positive ways such as increasing freedom of sexual expression, control over their bodies, sexual choices, and increasing equality with men in all spheres of life. However several negative consequences such as a rise in STD/HIV prevalence, commercial sex, and divorce rates have also been attributed to the ongoing sexual revolution in China. Recommendations combating these and suggestions for directions in future research are discussed.

    In today's gravity research there exist few modified gravitational theories which among other things predict the existence of a Yukawa-type correction to the classical gravitational potential. In this paper we study the Yukawa effect on the mean motion if any in a two-body scenario, assuming the influence of the existence of a possible Yukawa correction in the gravitational force of a primary. For that, we derive an equation in order to approximate the mean motion for secondary time rate of change of the orbiting body and its total variation over one revolution, under the influence of the non-Newtonian radial acceleration. Numerical results for Mercury and the companion star of the pulsar PSR 1913+16 are calculated. For specific values of the parameters α and λ, as given in the bibliography we have found that there is no corresponding Yukawa effect affecting the mean motion of the planet Mercury. On the other hand it appears that there is a periodic Yukawa effect that affects the mean motion of PSR+16 whose maximum numerical value occurs when the eccentric anomaly is equal to 180°.

    A method is given for the manufacture of silicon carbide bodies that are characterized by high density, high purity, and superior resistance to oxidative deterioration. Dense silicon bodies are obtained by a process in which granular silicon carbide, a carbonizable material, and a carbonaceous material are mixed together, the mixture is shaped as desired, and then the shape is fired in the presence of more than the stoichiometric amount of silicon. The carbonizable material preferably includes a temporary binder that is set before the firing step to hold the mix in shape for firing.

    Full Text Available It can be said that French Revolution, broke out in 1789, affected Europe deeply in freedom, equality, particularly with the ideas of nationalism. New values were introduced with the nationalism. With the new symbols, national states sought to give the community a new identity. Within this new formation, political powers in the adoption by the community and in its efforts to provide legitimacy, transfer tools to future generations are extremely important. In this context, the teaching of history is of great importance. In this study, a field survey was conducted on the lesson called Atatürk’s Principles and History of Revolution which have aims such as being able to teach the stages of foundation of the Republic of Turkey and to transfer the information to future generations. In that study, it was also aimed to find out information about the methodology of the lesson which has great importance on the development of the consciousness of Nationalism and citizenship and about founder of Turkish republic Ataturk. In this study a survey model was used. The students, who were studying in Kırşehir in the 2010-2011 academic years, set the population of the survey. To collect data in the survey, a questioner is used with the aim of discovering the opinions of the students about the course of “Atatürk’s Principles and History of Revolution. In the analysis, the t-test is used and the method of single factor variance analysis (ANOVA and percentage frequency is used.

  15. EDITORIAL: Permanent revolution - or evolution?

    Science.gov (United States)

    Dobson, Ken

    1998-03-01

    Honorary Editor It was that temporary Bolshevik Leon Trotsky who developed the principle of `permanent revolution', a principle that perhaps characterizes the recent history of education in (south) Britain more than does, say, principles traditionally associated with the Conservative or Labour parties. As this editorial is being written, changes are being made to primary school education, and the long-awaited details of the post-Dearing reorganizing of post-16 education are yet to hit the overful bookshelves and filing cabinets of school heads and examination board officials. But something unique has happened recently which might have surprised even Trotsky. The Secretary of State for Education has set up targets for primary school pupils' attainment and threatened (or promised) to resign if they are not met within the lifetime of our newly elected parliament. Of course, if Mr Blunkett is still in a position to resign at that stage he will have been the longest serving Secretary of State since time immemorial. But we should not carp: this is truly a revolutionary idea. Not the promise to resign - although this idea is not so fashionable now as it once was. The revolutionary idea is that a major change to an educational process is actually being made that carries with it a predicted and testable outcome. By contrast, when school physics was refreshed a generation ago by the introduction of Nuffield courses at both pre- and post-16 stages, no `targets' were set. I and many other physics teachers certainly preferred teaching these to teaching their predecessor syllabuses, and might even dare to assert that the pupils liked them too. But we still don't really know whether or not they learned more - or even better - physics. Very little happened as far as the outside world was concerned: the usual fraction of students gave up physics at the usual ages, and those who were examined didn't really get a better reward for their more up-to-date and more enjoyably learned

    The recent Ebola crisis has re-opened the debate on global health governance and the role of the World Health Organization. In order to analyze what is at stake, we apply two conceptual approaches from the social sciences - the work on gridlock and the concept of cosmopolitan moments - to assess the ability of the multilateral governance system to reform. We find that gridlock can be broken open by a health crisis which in turn generates a political drive for change. We show that a set of cosmopolitan moments have led to the introduction of the imperative of health in a range of policy arenas and moved health into 'high politics' - this has been called a political revolution. We contend that this revolution has entered a second phase with increasing interest of heads of state in global health issues. Here lies the window of opportunity to reform global health governance.

  18. Scientific pluralism and the Chemical Revolution.

    Kusch, Martin

    2015-02-01

    In a number of papers and in his recent book, Is Water H2O? Evidence, Realism, Pluralism (2012), Hasok Chang has argued that the correct interpretation of the Chemical Revolution provides a strong case for the view that progress in science is served by maintaining several incommensurable "systems of practice" in the same discipline, and concerning the same region of nature. This paper is a critical discussion of Chang's reading of the Chemical Revolution. It seeks to establish, first, that Chang's assessment of Lavoisier's and Priestley's work and character follows the phlogistonists' "actors' sociology"; second, that Chang simplifies late-eighteenth-century chemical debates by reducing them to an alleged conflict between two systems of practice; third, that Chang's evidence for a slow transition from phlogistonist theory to oxygen theory is not strong; and fourth, that he is wrong to assume that chemists at the time did not have overwhelming good reasons to favour Lavoisier's over the phlogistonists' views.

    This article gives a brief introduction to the English Revolution and describes a detailed study of influence, as well as the explanation of a representative and constitutional government. The English Revolution which happened in Britain is a histori-cal event of great influence. It abolished the autarchic system of king and began to rule the society by law. We can conclude that it created good political conditions for Britain to become a kingdom of modern civilization.
