Joseph Henry's Conception of Scientific Knowledge
Theerman, Paul
1997-04-01
Joseph Henry, America's premier physicist and physics teacher in the mid-nineteenth century, had decided views of scientific knowledge. These were expressed in two ways. First of all, scientific knowledge led to moral betterment. Thus the study of science was a morally good thing. This was not only because it led to the contemplation of God's creation, which was a standard reason justifying the study of science dating from the Scientific Revolution and even earlier. More importantly, the study of science itself was a moral discipline, imparting to scientists the habits and virtues of truthfulness, respect for others, care and diligence, and the discernment of meaningful patterns from experience. The moral ideals of science were expressed most strongly in Henry's upholding the international "Republic of Science"; conversely, cheapening science was a sign of moral failure. Second, for Henry and his generation, science provided a path to sure truth, separate from falsehood of both the politics and the quackery that characterized mid-century public life. Henry promoted this in his championing of the Smithsonian Institution a scientific establishment, against the ideas of others who wanted to make it a literary establishment or a training school for teachers. For Henry, the Smithsonian's scientific reputation would be established by relying on careful peer review in its publications, and supporting established scientists to write authoritative popular works. The purpose of both these activities was to raise the profile of science in the United States and further establish science and the scientific method as a guide to public life.

Henri Poincaré: Death centenary (1854-1912)
Heinzmann, Gerhard; Villani, Cédric
2014-08-01
The year 2012 marked the centenary of the death of Henri Poincaré (Nancy, 1854-Paris, 1912), and through the agency of the Henri-Poincaré Institute in Paris, the Henri-Poincaré Archives in Nancy and The London Mathematical Society, brought with it several exhibitions and meetings commemorating one of the greatest minds in contemporary times. Often referred to as the last polymath, Poincaré embraced multiple branches of mathematics, theoretical physics and celestial mechanics, and made significant contributions to philosophy of science (Heinzmann & Stump, Henri Poincaré, 2013). He wrote 25 textbooks and monographs, 500-plus articles, and was deeply involved in the organization and administration of science at both the national and international levels.1

Inverse modeling studies employing data collected from the classic Henry seawater intrusion problem give insight into several important aspects of inverse modeling of seawater intrusion problems and effective measurement strategies for estimation of parameters for seawater intrusion. Despite the simplicity of the Henry problem, it embodies the behavior of a typical seawater intrusion situation in a single aquifer. Data collected from the numerical problem solution are employed without added noise in order to focus on the aspects of inverse modeling strategies dictated by the physics of variable-density flow and solute transport during seawater intrusion. Covariances of model parameters that can be estimated are strongly dependent on the physics. The insights gained from this type of analysis may be directly applied to field problems in the presence of data errors, using standard inverse modeling approaches to deal with uncertainty in data. Covariance analysis of the Henry problem indicates that in order to generally reduce variance of parameter estimates, the ideal places to measure pressure are as far away from the coast as possible, at any depth, and the ideal places to measure concentration are near the bottom of the aquifer between the center of the transition zone and its inland fringe. These observations are located in and near high-sensitivity regions of system parameters, which may be identified in a sensitivity analysis with respect to several parameters. However, both the form of error distribution in the observations and the observation weights impact the spatial sensitivity distributions, and different choices for error distributions or weights can result in significantly different regions of high sensitivity. Thus, in order to design effective sampling networks, the error form and weights must be carefully considered. For the Henry problem, permeability and freshwater inflow can be estimated with low estimation variance from only pressure or only

Obituary: Henry Emil Kandrup, 1955-2003
Merritt, David; Gottesman, Stephen T.
2004-12-01
Henry Emil Kandrup died on 18 October 2003 at his home in Gainesville Florida. Henry was a theoretical astrophysicist specializing in the application of chaotic dynamics to stellar systems. At the time of his death, Henry was a Professor at the University of Florida where he had taught for 13 years. Henry was born in Manhasset, New York on July 24, 1955 and spent most of his childhood in Great Neck. His parents, Jytte and Fred, were immigrants from Denmark where his father had worked as a silver smith. Henry was a precocious child, skipping both third and fifth grades. With the help of Sidney Spivack, a professor of sociology at Columbia University, his parents enrolled Henry in the Brooks Preparatory School in Andover, Massachusetts. After graduating at age 16, Henry enrolled at Cornell, transferring to Princeton the following year. Henry's parents adored their only child and worked hard to provide him with intellectual opportunities. Henry became an accomplished musician (organ, piano, French horn) and linguist (English, Danish, German) and was a passionate devotee of opera and ballet. Henry received his PhD in 1980 from the University of Chicago, where his thesis advisor was James Ipser. He taught at Oakland University in Michigan and Syracuse University in New York before coming to the University of Florida in 1990. Henry was sui generis. He shunned conventionality in his personal appearance and in his public demeanor, and always chose forthrightness and candor over polite silence. But to those of us who knew Henry well, his bluntness was a reflection of his intellectual consistency. Henry always said exactly what he thought, both in his published work and his public presentations, and never compromised himself for the sake of appearances. Nothing that he said or wrote was less than fully thought out. Henry's PhD thesis was entitled "Stochastic Problems in Stellar Dynamics," and most of his subsequent research was in this field. Motion in stellar systems can be

Henri Poincaré a biography through the daily papers
Ginoux, Jean-Marc
2014-01-01
On July 17, 2012, the centenary of Henri Poincaré's death was commemorated; his name being associated with so many fields of knowledge that he was considered as the Last Universalist. In Pure and Applied Mathematics, Physics, Astronomy, Engineering and Philosophy, his works have had a great impact all over the world. Poincaré acquired in his lifetime such a reputation that, both nationally and internationally, his life and career were made the object of various articles in the daily papers not only in France, but also in the USA. Some of his philosophical concepts have even caused sharp controversies in the Press (as we will discover in this book).This work presents an original portrait of Henri Poincaré based on various press cuttings from The New York Times, The San Francisco Sunday Call, The Times, The Sun, The Washington Post that chronicled unknown anecdotes of his life (for example, his first name was actually not Henri, but Henry; he obtained his high school diploma in sciences with a zero in mathem...

Two-relaxation-time lattice Boltzmann method for the anisotropic dispersive Henry problem
Servan-Camas, Borja; Tsai, Frank T.-C.
2010-02-01
This study develops a lattice Boltzmann method (LBM) with a two-relaxation-time collision operator (TRT) to cope with anisotropic heterogeneous hydraulic conductivity and anisotropic velocity-dependent hydrodynamic dispersion in the saltwater intrusion problem. The directional-speed-of-sound technique is further developed to address anisotropic hydraulic conductivity and dispersion tensors. Forcing terms are introduced in the LBM to correct numerical errors that arise during the recovery procedure and to describe the sink/source terms in the flow and transport equations. In order to facilitate the LBM implementation, the forcing terms are combined with the equilibrium distribution functions (EDFs) to create pseudo-EDFs. This study performs linear stability analysis and derives LBM stability domains to solve the anisotropic advection-dispersion equation. The stability domains are used to select the time step at which the lattice Boltzmann method provides stable solutions to the numerical examples. The LBM was implemented for the anisotropic dispersive Henry problem with high ratios of longitudinal to transverse dispersivities, and the results compared well to the solutions in the work of Abarca et al. (2007).

This essay will consider recent shifts in performance representations of England and the exotic ‘other’ in Shakespeare’s Henry IV, Henry V and Henry VI plays. By tracing the texts’ varied representations of non-English Britons and those for whom English is not their mother tongue (such as Owen Glyndwr in 1 Henry IV and Princess Catherine in Henry V), recent criticism has identified that Shakespeare’s narrative portrays the challenges of assimilating ‘otherness’ within English culture.

Little is generally known of Henry Gray, the author of Gray's Anatomy, and even less of his colleague Henry Vandyke Carter, who played a vital role in the dissections and illustrations leading to the production of the first volume in 1859. This essay attempts to sketch briefly the salient, know aspects of these two men and their divergent careers. It traces succinctly the subsequent fate of the unique anatomy book that has influenced and instructed almost every student of medicine. (c) 2009 Wiley-Liss, Inc.

Thomas Henry Huxley et la Bible Thomas Henry Huxley and the Bible
Directory of Open Access Journals (Sweden)
Christophe Duvey
2009-10-01
Full Text Available Thomas Henry Huxley devoted several essays to the study of the Bible. This interest can only be accounted for if his ideas on history, religion as well as epistemology are examined. According to him, a struggle between free thought and supernaturalism was culminating during the Victorian era, hence the need for a “New Reformation” which was heir to the ideals of freedom defended by the humanists of the Renaissance. This movement opposed the principles of the supporters of what he called “ecclesiasticism”. The advocates of the “New Reformation” could rely on the progress of modern science, and agnosticism, which Huxley identified with scientific method, became its epistemological foundation. As a result, Huxley thought that the authority of physical science was in conflict with the infallibility of the Scriptures and with the theological arguments which rested on it, and this notably led him to the conclusion that the biblical narrative of the Flood was unhistorical. The naturalisation of the Scriptures seems then logically to follow his philosophical views based on the limits of human knowledge.It appears that it was the question of authority which underlay Huxley’s interest in the Bible. He thought that the authority of the Scriptures must be replaced by that of science.

Allisy, A.
1996-01-01
This paper recalls the history of the Becquerel family, the fascinating time of the discovery of radioactivity as well as some important related research published before the radium age. Henri Becquerel was the third in the line of a family of scientists which extended over more than a hundred years. Following in the footsteps of his father and grandfather gave him a thorough grounding in scientific research methods. Science at the turn of the century was very exciting, the discovery of X rays had just been announced and scientists everywhere were hoping to discover new phenomena. (author)

Contaminant Monitoring Strategy for Henrys Lake, Idaho
Energy Technology Data Exchange (ETDEWEB)

flows can occur as a result of severe cattle grazing along riparian areas and deltas. Groundwater and springs also feed the lake, and are likely critical for oxygen supply during winter stratification. During the winter of 1991, Henrys Lake experienced low dissolved oxygen levels resulting in large fish kills. It is thought that thick ice cover combined with an increase in nutrient loads created conditions resulting in poor water quality. The Idaho Department of Health and Welfare, DEQ is currently conducting a study to determine the water quality of Henrys Lake, the sources contributing to its deterioration, and potential remedial actions to correct problem areas.

VoxHenry: FFT-Accelerated Inductance Extraction for Voxelized Geometries
Yucel, Abdulkadir C.
2018-01-18
VoxHenry, a fast Fourier transform (FFT)-accelerated integral-equation-based simulator for extracting frequency-dependent inductances and resistances of structures discretized by voxels, is presented. VoxHenry shares many features with the popular inductance extractor, FastHenry. Just like FastHenry, VoxHenry solves a combination of the electric volume integral equation and the current continuity equation, but with three distinctions that make VoxHenry suitable and extremely efficient for analyzing voxelized geometries: 1) it leverages a carefully selected set of piecewise-constant and piecewise-linear basis functions; 2) it exploits FFTs to accelerate the matrix-vector multiplications during the iterative solution of system of equations; and 3) it employs a sparse preconditioner to ensure the rapid convergence of iterative solution. VoxHenry is capable of accurately computing frequency-dependent inductances and resistances of arbitrarily shaped and large-scale structures on a desktop computer. The accuracy, efficiency, and applicability of VoxHenry are demonstrated through inductance analysis of various structures, including square and circular coils as well as arrays of RF inductors (situated over ground planes).

Poincaré, philosopher of science problems and perspectives
DiSalle, Robert
2014-01-01
This volume presents a selection of papers from the Poincaré Project of the Center for the Philosophy of Science, University of Lisbon, bringing together an international group of scholars with new assessments of Henri Poincaré's philosophy of science—both its historical impact on the foundations of science and mathematics, and its relevance to contemporary philosophical inquiry. The work of Poincaré (1854-1912) extends over many fields within mathematics and mathematical physics. But his scientific work was inseparable from his groundbreaking philosophical reflections, and the scientific ferment in which he participated was inseparable from the philosophical controversies in which he played a pre-eminent part. The subsequent history of the mathematical sciences was profoundly influenced by Poincaré’s philosophical analyses of the relations between and among mathematics, logic, and physics, and, more generally, the relations between formal structures and the world of experience. The papers in this col...

Henry VIII, McLeod syndrome and Jacquetta's curse.
Stride, P; Lopes Floro, K
2013-01-01
The mental decline of King Henry VIII from being a jovial, charismatic and athletic young man into an increasingly paranoid, brutal tyrant in later life, ever more concerned at his lack of one or more male heirs, has attracted many medical diagnostic theories. Previous hypotheses have included diabetes, syphilis and hypothyroidism, among others. However, these inadequately explain Henry's failure to produce a male heir, despite multiple pairings. The latest postulated diagnoses for Henry are the coexistence of both Kell blood group antigenicity (possibly inherited from Jacquetta Woodville, Henry's maternal great grandmother) causing related impaired fertility, and McLeod syndrome, causing psychotic changes. As the mutated McLeod protein of the syndrome significantly reduces the expression, effectively inactivating the Kell antigen, we critically review this theory, examining in detail the pathophysiology of these conditions and assessing the genealogy of Henry VIII and its effect in subsequent generations.

Obituary: Henry Albers (1925-2009)
Chromey, Fred
2011-12-01
Henry Albers, professor of astronomy at Vassar College for over thirty years, died March 29, 2009, in Fairhope, Alabama. For his work at Vassar, where he held the Maria Mitchell Chair, Albers received the first Maria Mitchell Women in Science Award for his inspiration of women astronomers. He said "In the final analysis it is the students who bring the joy into teaching." As a professional astronomer, Albers did observational work on Galactic structure in the southern Milky Way, and on the structure of the Magellanic Clouds. In retirement, Albers published Maria Mitchell - A Life in Journals and Letters, the firsthand account of America's first woman astronomer. Albers's research was on photographic near-infrared spectroscopy of red giant stars in the southern Milky Way, some proper motion studies, and on the structure of the Magellanic Clouds. A series of seven NSF grants supported his six trips to Chile to make spectroscopic observations, as well as his sabbatical collaborations at Minnesota, Leiden, and the Royal Observatory in Edinburgh. Henry Albers arrived at Vassar in 1958, to find an astronomy program that had been recently absorbed by the physics department, and that was suffering neglect after the retirement of Maud Makemson. For the next 31 years, with incredible energy -- he sometimes taught seven courses a year -- he built the astronomy program into one double in size (from one to two tenure lines), whose th century facilities have been replaced with a st century observatory. For a remarkable stretch of 20-some-years, Albers and physicist Bob Stearns, with considerable grace, alternated chairmanship of the joint department of physics and astronomy. Henry Albers was a devoted citizen of Vassar College and an enthusiastic participant in the process of faculty governance at that institution. He would have been the first to concede that his enthusiasm was sometimes excessive, and that his contributions at faculty meetings occasionally failed to move the

Full Text Available In this paper the author discusses the views and statements of the French football player Thierry Henry he gave after his illegal play during the playoff match between France and the Republic of Ireland to claim one of the final spots in the World Cup 2010 in South Africa. First, by controlling the ball with his hand before passing it on for the goal Henry has shown disregard for the constitutive rules of football. Then, by stating that he is "not a referee" he demonstrated that for some players rules are not inherent to football and that they can be relativized, given that for them winning is the goal of the highest ontological status. Furthermore, he has rejected the rules of sportsmanship, thus expressing his opinion that the opponents are just obstacles which have to be removed in order to achieve your goals. Henry's action has disrupted major moral values, such as justice, honesty, responsibility and beneficence. The rules of fair play have totally been ignored both in Henry's action and in the Football Association of France's unwillingness to comment on whether a replay should take place. They have ignored one of the basic principles stated in the "Declaration of the International Fair Play Committee", according to which, fair play is much more than playing to the rules of the game; it's about the attitude of the sportsperson. It's about respecting your opponent and preserving his or her physical and psychological integrity.

Full Text Available In a classical paper Henry set up a conceptual model for simulating saltwater intrusion into coastal aquifers. Up to now the problem has been taken up by software developers and modellers as a benchmark for codes simulating coupled flow and transport in porous media. The Henry test case has been treated using different numerical methods based on various formulations of differential equations. We compare several of these approaches using multiphysics software. We model the problem using Finite Elements, utilizing the primitive variables and the streamfunction approach, both with and without using the Oberbeck-Boussinesq assumption. We compare directly coupled solvers with segregated solver strategies. Changing finite element orders and mesh refinement, we find that models based on the streamfunction converge 2-4 times faster than runs based on primitive variables. Concerning the solution strategy, we find an advantage of Picard iterations compared to monolithic Newton iterations.

Henry David Thoreau was wholeheartedly in love with nature and he devoted almost all his life time to observation, appreciation and study of nature. Thus he formed a deep understanding of nature. In 1845, Thoreau began a two-year and two-month residence at Walden Pond. His life was lonely but full of fragrance. He wanted to live meaningfully, confront the essential facts of life and live a simple life. Based on the review of the literature related to this topic, this paper aims to study Henry David Thoreau’s spiritual world, especially reflected in his famous book-Walden.

Bergson and the unification of the sciences
International Nuclear Information System (INIS)
Stapp, H.P.
1985-02-01
Louis De Broglie and M. Capek have described some interesting similarities between the philosophical ideas of Henri Bergson and the profound conceptual changes introduced into physics by quantum theory and the theory of relativity. These similarities are neither identities nor direct causal links, and hence physicists are likely to regard them as mere curiosities having no import for the development of science. However, another view is possible: if Bergson's thinking presaged, at least in spirit, these two revolutionary advances in physics then his intuitions may accord sufficiently with nature to provide useful guidance in the approach to other deep problems in science. Pursuing this idea I shall indicate here how Bergson's intuitions suggest a possible approach to perhaps the fundamental problem of contemporary science, namely the problem of constructing an overarching theoretical framework for unifying the various branches of science from psychology through biology to physics. 19 refs

[Hypospadia and infertility of Henry II of France (1519-1559)].
Hatzinger, M; Al-Shajlawi, S; Sohn, M
2014-03-01
Henry II (1519-1559) of France was the second son of Francis I (1494-1547) and Claude de France (1498-1524) born in 1519 in St. Germain-en-Laye. After his older brother's and his father's death in 1547, he was anointed the French king in Reims. In 1533 already, as a 14-year-old boy, for reasons of state, he was married to the same aged Catherine de Medici (1519-1589), as her uncle was Pope Clement VII (1478-1534). The marriage remained childless for 11 years since Henry, due to a distinct hypospadia and a completely sexually inexperienced wife was unable to conceive children with her. His existing liaison to Diane de Poitiers (1499-1566) - a 19-year-older maid of honor of his father Francis I from 1537 until his death - influenced his sexual life immensely.The blame for the childless marriage was placed primarily on his wife, as Henry had become father of an illegitimate daughter with a mistress. Catherine then underwent all possible medical and alchemical procedures to finally give birth to the hoped Dauphin. Ironically, her rival for the favor of her husband, Diane de Poitiers was one of her greatest allies. She made clear that the cause lay with Henry and not with his wife. This was confirmed by the added solid physician Jean Fernel (1497-1558). His treatment of Henry and the simultaneous training of the unexperienced Catherine by Diane de Poitiers led to success.The result was the birth of Francis II (1544-1560) in 1544, the first of 10 children in 12 years. Thus, the dynasty was saved. After the death of Henry in a tragic tournament accident in 1559, three of his sons became kings of France. But the line of Valois remained without further descendants and was continued by Henry IV, the first Bourbon king in 1589.

The first edition of Anatomy Descriptive and Surgical (1858) was greeted with accolades, but also provoked serious controversy concerning Henry Gray's failure to acknowledge the work of earlier anatomists. A review in the Medical Times (1859) accused Gray of intellectual theft. The journal took the unusual step of substantiating its indictment by publishing twenty parallel texts from Gray and from a pre-existing textbook, Quain's Anatomy. At the recent "Vesalius Continuum" conference in Zakynthos, Greece (2014) Professor Brion Benninger disputed the theft by announcing from the floor the results of a computer analysis of both texts, which he reported exonerated Gray by revealing no evidence of plagiarism. The analysis has not been forthcoming, however, despite requests. Here the historian of Gray's Anatomy supplements the argument set out in the Medical Times 150 years ago with data suggesting unwelcome personality traits in Henry Gray, and demonstrating the utility of others' work to his professional advancement. Fair dealing in the world of anatomy and indeed the genuineness of the lustre of medical fame are important matters, but whether quantitative evidence has anything to add to the discussion concerning Gray's probity can be assessed only if Benninger makes public his computer analysis. © 2015 Wiley Periodicals, Inc.

Born in Paris on September 28, 1852, son of an eastern railways' employee and of a dressmaker, Henri Moissan's secondary schooling in Meaux did not allow him to get access to the sesame diploma "baccalauréat" (GCE). In 1869, he did obtain a special certificate of secondary schooling so that he could become an apprentice in watch making. That could have been the end of the story, but dreadful event for France appeared to have beneficial effects for Moissan. Under the threat of the Prussian army, Moissan's family took refuge near Paris. This gave the young Henri the opportunity to register as a student for the second-class pharmacy diploma, which did not need, at the time, the GCE. Moissan became then a trainee in pharmacy in 1871. Meanwhile, he followed the special schooling of "Ecole de chimie" founded by E. Frémy, and then joined the laboratory of Dehérain at the Museum, where he worked in plant physiology. He finally obtained the famous "baccalauréat" (GCE) and could register as a student in first-class pharmacy. He became a pharmacist as well as a doctor in sciences. In 1883, Moissan was named professor at the school of pharmacy in Paris. In 1886, he isolated fluorine by electrolysis of fluorhydric acid, in the presence of potassium fluoride, at a low temperature. He then studied diamond synthesis and gave a start to high temperature chemistry, designing his famous furnace. These findings and many others allowed Moissan to rise to membership in many learned academies around the world. Crowning achievement, Moissan won the Nobel Prize in 1906. A man of culture, collector of autographs and paintings, he died in 1907. Nothing of that would have been possible if there had not been a second-class pharmacist diploma. The history of Henri Moissan is one of a rise from apprenticeship to the Nobel Prize.

Though guided-inquiry learning, discovery learning, student-centered learning, and problem-based learning are commonly believed to be recent new approaches to the teaching of chemistry, in fact, the concept dates back to the late 19th century. Here, we will show that it was the British chemist, Henry Armstrong, who pioneered this technique,…

Design of a gap tunable flux qubit with FastHenry
Akhtar, Naheed; Zheng, Yarui; Nazir, Mudassar; Wu, Yulin; Deng, Hui; Zheng, Dongning; Zhu, Xiaobo
2016-12-01
In the preparations of superconducting qubits, circuit design is a vital process because the parameters and layout of the circuit not only determine the way we address the qubits, but also strongly affect the qubit coherence properties. One of the most important circuit parameters, which needs to be carefully designed, is the mutual inductance among different parts of a superconducting circuit. In this paper we demonstrate how to design a gap-tunable flux qubit by layout design and inductance extraction using a fast field solver FastHenry. The energy spectrum of the gap-tunable flux qubit shows that the measured parameters are close to the design values.

Science and technology related global problems: An international survey of science educators
Bybee, Rodger W.; Mau, Teri
This survey evaluated one aspect of the Science-Technology-Society theme, namely, the teaching of global problems related to science and technology. The survey was conducted during spring 1984. Two hundred sixty-two science educators representing 41 countries completed the survey. Response was 80%. Findings included a ranking of twelve global problems (the top six were: World Hunger and Food Resources, Population Growth, Air Quality and Atmosphere, Water Resources, War Technology, and Human Health and Disease). Science educators generally indicated the following: the science and technology related global problems would be worse by the year 2000; they were slightly or moderately knowledgeable about the problems; print, audio-visual media, and personal experiences were their primary sources of information; it is important to study global problems in schools; emphasis on global problems should increase with age/grade level; an integrated approach should be used to teach about global problems; courses including global problems should be required of all students; most countries are in the early stages of developing programs including global problems; there is a clear trend toward S-T-S; there is public support for including global problems; and, the most significant limitations to implementation of the S-T-S theme (in order of significance) are political, personnel, social, psychological, economic, pedagogical, and physical. Implications for research and development in science education are discussed.

Should bulk cloudwater or fogwater samples obey Henry's law?
Pandis, Spyros N.; Seinfeld, John H.
1991-06-01
Mixing of droplets with different pH that are individually in Henry's law equilibrium with the surrounding atmosphere always results in a bulk mixture that is supersaturated with weak acids like S(IV) and HCOOH, and bases like NH3 with respect to the original atmosphere. High supersaturations result only when the pH of the bulk droplet mixture exceeds the pKa of the species, in which pH range large pH differences among droplets of different sizes lead to large deviations from Henry's law for the bulk mixture. The deviation is shown to depend on the ratio of the arithmetic mean to the harmonic mean of the hydrogen ion concentrations of the droplets with the liquid water content used as weighting factor in the calculation of the means. The theory developed can explain observed discrepancies from Henry's law in atmospheric samples and also other observed phenomena like the reported increase of pH values of bulk aqueous samples during storage.

Armour and William Henry Holmes in 1895, a little more than a year after the Museum was established. Looking back after a career of almost 60 years as an anthropologist, and having twice been honored as the outstanding practitioner in the field, Holmes described the trip to Mexico (the only expedition he led during his brief tenure as the Museum's first Curator of Anthropology as "one of the most gratifying and important events of my life." It was also one of the most important events in the history of anthropology at the Museum.

Full Text Available Miss Grief is a story by Constance Fenimore Woolson, an American novelist who often wrote about the difficulty a woman had in becoming an artist — a writer or a painter — in the nineteenth century. This tale is a very strange text, a kind of anticipation of a meeting to come, in Italy, in 1880, between Woolson and Henry James, and a friendship which lasted until the former’s death in 1894. For thirteen years, both writers would share a common inspiration. Death itself could not break the links between the two authors, who were connected even when settled in different European countries. William James, who was a member of the American Society for Psychical Research, probably helped his brother Henry to communicate — or so it appears — in some way with Woolson, even after her fatal accident, or possible suicide, in Venice. Henry James probably had in mind Miss Grief, a story by his dead friend, before writing some of his books. Indeed, Woolson had been the first to develop the image of “the figure in the carpet,” which was later transformed by Henry James. Woolson was also the first to devise a plot which Henry James would later use as a canvas for his novel The Wings of the Dove. What is an author and what is authorship? It seems impossible to separate what is Woolson’s and what is Henry James’s in four works of fiction that are in fact to be read together : Miss Grief, The Figure in the Carpet, The Beast in the Jungle, The Wings of the Dove.

Pornografia e transgressão na obra literária de Henry Miller
Directory of Open Access Journals (Sweden)
Raquel Catunda Pereira
2016-07-01
Full Text Available The North American writer Henry Miller was marginalized by literary critics since the first publications of his works in the 40s. Accused of being a pornographic text, the book Tropic of Cancer (1934 was forbidden in many countries. This article aims to analyze the obscene in Henry Miller’s work to prove that, beyond the erotic intention, Miller’s books are an expression of freedom and rejection of moral standards. In order to achieve our goal, we will use as theoretical basis the articles Criticismo e sexualidade: uma leitura de Tropico of Capricorn de Henry Miller, by Flávia Andréa Rodrigues Benfatt, and Literatura marginal americana: do épico confessional ao niilismo erótico, by Lainister de Oliveira. The texts mentioned above grant us the argumentation necessary to the analysis of pornographic discourse in Henry Miller’s literary works as the author’s aesthetics choice of taking himself as a transgressor in a decadent society.

Henry Beecher's Contributions to the Ethics of Clinical Research.
Veatch, Robert M
2016-01-01
In the 1950s and '60s, Henry Beecher pioneered the discussion of the ethics of clinical research, leading eventually to the publication of the famous New England Journal of Medicine article summarizing 22 research studies that Beecher suggests were unethical. Those studies generally showed a pattern of posing serious risks to subjects without anticipated proportional benefit. Beecher famously claimed that the problem was not that researchers were malicious or evil; rather, he claimed the problem was they manifested thoughtlessness or carelessness. He called for more rigorous self-scrutiny rather than public review.This article argues that Beecher's reliance on conscientious investigators is problematic. In particular, it focuses on benefits and harms to the exclusion of other moral criteria. However, both research subjects and public regulators are also concerned about autonomy and the consent requirement, confidentiality, and fairness in subject selection and research design. The movement in the 1970s toward more public scrutiny was critical, even though Beecher was right in holding that it was not "vicious disregard for subject welfare" that explained unethical protocols.

2002-01-01
This article presents the scientific saga of the Becquerel family. 4 generations of Becquerel Antoine-Cesar (1788-1878), Edmond (1820-1891), Henri (1852-1906) and Jean (1878-1953) were involved in scientific activities at the highest level. Henri was awarded the Nobel prize of physics (shared with Pierre and Marie Curie) in 1903 for the discovery of radioactivity. The author shows that the discovery of radioactivity was due to talent, family emulation, genetics and chance. (A.C.)

Physics Problems Based on Up-to-Date Science and Technology.
Folan, Lorcan M.; Tsifrinovich, Vladimir I.
2007-03-01
We observe a huge chasm between up-to-date science and undergraduate education. The result of this chasm is that current student interest in undergraduate science is low. Consequently, students who are graduating from college are often unable to take advantage of the many opportunities offered by science and technology. Cutting edge science and technology frequently use the methods learned in undergraduate courses, but up-to-date applications are not normally used as examples or for problems in undergraduate courses. There are many physics problems which contain information about the latest achievements in science and technology. But typically, the level of these problems is too advanced for undergraduates. We created physics problems for undergraduate science and engineering students, which are based on the latest achievements in science and technology. These problems have been successfully used in our courses at the Polytechnic University in New York. We believe that university faculty may suggest such problems in order to provide information about the frontiers of science and technological, demonstrate the importance of undergraduate physics in solving contemporary problems and raise the interest of talented students in science. From the other side, our approach may be considered an indirect way for advertising advanced technologies, which undergraduate students and, even more important, future college graduates could use in their working lives.

Evolution of managerial problems from the perspective of management science
Directory of Open Access Journals (Sweden)
Marek Szarucki
2015-12-01
Full Text Available Managerial problems and the process of their solving play an important role both in the theory of management science and practice of organisations’ functioning. There is a gap in the literature related to the evolution of management problems in the context of the methodological approaches to solve them. The main goal of this paper was to analyse the evolution of the managerial problems from the perspective of management science and to present dominant methodological approaches for problem solving. Based on the extensive literature analysis in the discipline of management science, the evolution of the managerial problems was described with relation to the sixteen streams of management science. The author reviewed the selected classifications of the management theory as well as proposed his own perspective, which took into account managerial problems and their evolution over time. Moreover, there was presented an attempt to depict sources of management problems from the historical perspective within the methodological approaches of management science. Despite the broad view on management problems presented in this paper, such perspective gives a good ground for developing new more specific problem classifications, addressing different facets of managerial problems.

Family-based interventions to prevent childhood obesity depend upon parents' taking action to improve diet and other lifestyle behaviours in their families. Programmes that attract and retain high numbers of parents provide an enhanced opportunity to improve public health and are also likely to be more cost-effective than those that do not. We have developed a theory-informed optimisation intervention to promote parent engagement within an existing childhood obesity prevention group programme, HENRY (Health Exercise Nutrition for the Really Young). Here, we describe a proposal to evaluate the effectiveness of this optimisation intervention in regard to the engagement of parents and cost-effectiveness. The Optimising Family Engagement in HENRY (OFTEN) trial is a cluster randomised controlled trial being conducted across 24 local authorities (approximately 144 children's centres) which currently deliver HENRY programmes. The primary outcome will be parental enrolment and attendance at the HENRY programme, assessed using routinely collected process data. Cost-effectiveness will be presented in terms of primary outcomes using acceptability curves and through eliciting the willingness to pay for the optimisation from HENRY commissioners. Secondary outcomes include the longitudinal impact of the optimisation, parent-reported infant intake of fruits and vegetables (as a proxy to compliance) and other parent-reported family habits and lifestyle. This innovative trial will provide evidence on the implementation of a theory-informed optimisation intervention to promote parent engagement in HENRY, a community-based childhood obesity prevention programme. The findings will be generalisable to other interventions delivered to parents in other community-based environments. This research meets the expressed needs of commissioners, children's centres and parents to optimise the potential impact that HENRY has on obesity prevention.

Henry James – Modern Theoretician of Narration
Directory of Open Access Journals (Sweden)
Alexandra - Denisa IGNA
2013-01-01
Full Text Available Henry James, properly named world writer, was one of the first modern novelists, with an exigent writing conscience. The American writer subverted the prejudgement of the omniscient author in favour of the narration which is centred on the characters’ point of view, thus modernising the novel before V. Woolf, Huxley, Thomas Mann, or in our case Camil Petrescu and G. Călinescu. Some bio-bibliographical information familiarises the reader with the life and work of this writer. The larger part of the article is dedicated to a case study of the novel with the metaphorical title: The Figure in the Carpet, where Henry James tries to illustrate in an artistic manner his conception regarding the profundity and ineffability of the literary creation. The conclusion which the author reaches, alternating the familiar plan of the relationship between a married couple with the esthetical plan, is that the relationship between writer and his work represents an act of fully intimacy, just like a ceremony that takes place in the wedding night

The interrelationship between mathematics and science education has frequently been emphasized, and common goals and approaches have often been adopted between disciplines. Improving students' problem-solving skills in mathematics and science education has always been given special attention; however, the problem-posing approach which plays a key role in mathematics education has not been commonly utilized in science education. As a result, the purpose of this study was to better determine the effects of the problem-posing approach on students' problem-solving skills and metacognitive awareness in science education. This was a quasi-experimental based study conducted with 61 chemistry and 40 physics students; a problem-solving inventory and a metacognitive awareness inventory were administered to participants both as a pre-test and a post-test. During the 2017-2018 academic year, problem-solving activities based on the problem-posing approach were performed with the participating students during their senior year in various university chemistry and physics departments throughout the Republic of Turkey. The study results suggested that structured, semi-structured, and free problem-posing activities improve students' problem-solving skills and metacognitive awareness. These findings indicated not only the usefulness of integrating problem-posing activities into science education programs but also the need for further research into this question.

Evaluating Henry's law constant of N-nitrosodimethylamine (NDMA).
Haruta, Shinsuke; Jiao, Wentao; Chen, Weiping; Chang, Andrew C; Gan, Jay
2011-01-01
N-Nitrosodimethylamine (NDMA), a potential carcinogen, may contaminate the groundwater when the reclaimed wastewater is used for irrigation and groundwater recharge. Henry's law constant is a critical parameter to assess the fate and transport of reclaimed wastewater-borne NDMA in the soil profile. We conducted a laboratory experiment in which the change of NDMA concentration in water exposed to the atmosphere was measured with respect to time and, based on the data, obtained the dimensionless Henry's law constant (K(H)') of NDMA, at 1.0 x 10(-4). The K(H)' suggests that NDMA has a relatively high potential to volatilize in the field where NDMA-containing wastewater is used for irrigation and the volatilization loss may be a significant pathway of NDMA transport. The experiment was based on the two boundary-layer approach of mass transfer at the atmosphere-water interface. It is an expedient method to delineate K(H)' for volatile or semi-volatile compounds present in water at low concentrations.

[The materialistic strategy of Henry Howard, a Québec alienist (1815-1887).].
Fugère, A
1978-01-01
At the end of the 19th century, Henry Howard appeared as the first Quebec "aliéniste" to attempt to develop an inclusive theoretical treatise on the question of madness. Why this sudden upheaval ? There existed numerous european theories ; that might have sufficed. The author attempts to show the multiple connections of this theoretical pro-lect to the socio-political problems of québécois society. Howard tries, from the perspective of the theory which he elaborates, to intervene in the major discussions affecting Quebec: ultra montanism, the problem of universal compusory education, public morality. At a more professional level he attempts to intervene in the legal dispute opposing judicial and medical competence in the cases of insanity pleas, as well as in the question of the scientific and social status of the "aliéniste". The involvement in these struggles manifests itself in Howard's treatise as much at the level of the concepts themselves, and their architecture, as at the thematic level and in the applications which he naturally draws. It is not onty external and contingent but works on the text from the inside as well. The article attempts to suggest that at the very moment that the treatise on the alienated-which would become the "science" that we know today- seeks to structure itself into a theory, it cannot break its attachment to its determining social context and that, ignoring its ideological role it, in truth, succeeds only in creating illusion and the impression of a progressive process, all the while being circumstantial and having a verted interest.

A group-contribution method based on scaled-particle theory was developed to predict Henry's constants for six families of persistent organic pollutants: polychlorinated benzenes, polychlorinated biphenyls, polychlorinated dibenzodioxins, polychlorinated dibenzofurans, polychlorinated naphthalenes, and polybrominated diphenyl ethers. The group-contribution model uses limited experimental data to obtain group-interaction parameters for an easy-to-use method to predict Henry's constants for systems where reliable experimental data are scarce. By using group-interaction parameters obtained from data reduction, scaled-particle theory gives the partial molar Gibbs energy of dissolution, Δg̅ 2 , allowing calculation of Henry's constant, H 2 , for more than 700 organic pollutants. The average deviation between predicted values of log H 2 and experiment is 4%. Application of an approximate van't Hoff equation gives the temperature dependence of Henry's constants for polychlorinated biphenyls, polychlorinated naphthalenes, and polybrominated diphenyl ethers in the environmentally relevant range 0-40 °C.

The delusion of the Master: the last days of Henry James.
Bartolomeo, Paolo
2013-11-01
The novelist Henry James shared with his brother William, the author of the Principles of Psychology, a deep interest in the ways in which personal identity is built through one's history and experiences. At the end of his life, Henry James suffered a vascular stroke in the right hemisphere and developed a striking identity delusion. He dictated in a perfectly clear and coherent manner two letters as if they were written by Napoleon Bonaparte. He also showed signs of reduplicative paramnesia. Negative symptoms resulting from right hemisphere damage may disrupt the feelings of "warmth and intimacy and immediacy" and the "resemblance among the parts of a continuum of feelings (especially bodily feelings)", which are the foundation of personal identity according to William James. On the other hand, a left hemisphere receiving inadequate input from the damaged right hemisphere may produce positive symptoms such as delusional, confabulatory narratives. Other fragments dictated during Henry James's final disease reveal some form of insight, if partial and disintegrated, into his condition. Thus, even when consciousness is impaired by brain damage, something of its deep nature may persist, as attested by the literary characteristics of the last fragments of the Master.

Full Text Available The Henry problem (HP continues to play a useful role in theoretical and practical studies related to seawater intrusion (SWI into coastal aquifers. The popularity of this problem is attributed to its simplicity and precision to the existence of semi-analytical (SA solutions. The first SA solution has been developed for a high uniform diffusion coefficient. Several further studies have contributed more realistic solutions with lower diffusion coefficients or velocity-dependent dispersion. All the existing SA solutions are limited to homogenous and isotropic domains. This work attempts to improve the realism of the SA solution of the dispersive HP by extending it to heterogeneous and anisotropic coastal aquifers. The solution is obtained using the Fourier series method. A special hydraulic conductivity–depth model describing stratified heterogeneity is used for mathematical convenience. An efficient technique is developed to solve the flow and transport equations in the spectral space. With this technique, we show that the HP can be solved in the spectral space with the salt concentration as primary unknown. Several examples are generated, and the SA solutions are compared against an in-house finite element code. The results provide high-quality data assessed by quantitative indicators that can be effectively used for code verification in realistic configurations of heterogeneity and anisotropy. The SA solution is used to explain contradictory results stated in the previous works about the effect of anisotropy on the saltwater wedge. It is also used to investigate the combined influence of stratification and anisotropy on relevant metrics characterizing SWI. At a constant gravity number, anisotropy leads to landward migration of the saltwater wedge, more intense saltwater flux, a wider mixing zone and shallower groundwater discharge zone to the sea. The influence of stratified heterogeneity is more pronounced in highly anisotropic aquifers. The

Complex network problems in physics, computer science and biology
Cojocaru, Radu Ionut
There is a close relation between physics and mathematics and the exchange of ideas between these two sciences are well established. However until few years ago there was no such a close relation between physics and computer science. Even more, only recently biologists started to use methods and tools from statistical physics in order to study the behavior of complex system. In this thesis we concentrate on applying and analyzing several methods borrowed from computer science to biology and also we use methods from statistical physics in solving hard problems from computer science. In recent years physicists have been interested in studying the behavior of complex networks. Physics is an experimental science in which theoretical predictions are compared to experiments. In this definition, the term prediction plays a very important role: although the system is complex, it is still possible to get predictions for its behavior, but these predictions are of a probabilistic nature. Spin glasses, lattice gases or the Potts model are a few examples of complex systems in physics. Spin glasses and many frustrated antiferromagnets map exactly to computer science problems in the NP-hard class defined in Chapter 1. In Chapter 1 we discuss a common result from artificial intelligence (AI) which shows that there are some problems which are NP-complete, with the implication that these problems are difficult to solve. We introduce a few well known hard problems from computer science (Satisfiability, Coloring, Vertex Cover together with Maximum Independent Set and Number Partitioning) and then discuss their mapping to problems from physics. In Chapter 2 we provide a short review of combinatorial optimization algorithms and their applications to ground state problems in disordered systems. We discuss the cavity method initially developed for studying the Sherrington-Kirkpatrick model of spin glasses. We extend this model to the study of a specific case of spin glass on the Bethe

The primary assertion is that this article argues that the recovery in production of hydropower in Henry Borden (UHB) is the reduction of environmental liabilities in the Billings reservoir. In this context, the aim of this paper is to provide a first consideration of the possibility of recovery of production Henry Borden hydropower plant of recovering the multiple uses of the reservoir. From this perspective, we interviewed representatives of CETESB (Sanitation Environmental Technology Company) and EMAE (Metropolitan Water and Energy Company SA) for consideration of actions that include environmental policies aimed at increasing the production of electricity in Henry Borden in order to obtain results that may contribute to the multiple uses of the Billings reservoir. Noting that the range of laws aimed at protecting the water sources was limited to disjointed public policy that has reduced the resilience of the Billings reservoir. (author)

Oxalate Content of the Herb Good-King-Henry, Blitum Bonus-Henricus

Wanying Li
2015-05-01
Full Text Available The total, soluble and insoluble oxalate contents of the leaves, stems and buds of Good-King-Henry (Blitum Bonus-Henricus were extracted and measured using HPLC chromatography. The large, mature leaves contained 42% more total oxalate than in the small leaves and the soluble oxalate content of the large leaves was 33% higher than the smaller leaves. Cooking the mixed leaves, stems and buds in boiling water for two minutes significantly (p < 0.05 reduced the total oxalate when compared to the raw plant parts. Pesto sauce made from mixed leaves contained 257 mg total oxalate/100 g fresh weight; this was largely made up of insoluble oxalates (85% of the total oxalate content. Soup made from mixed leaves contained lower levels of total oxalates (44.26 ± 0.49 mg total oxalate/100 g fresh weight and insoluble oxalate made up 49% of the oxalate contents. The levels of oxalates in the Good-King-Henry leaves were high, suggesting that the leaves should be consumed occasionally as a delicacy because of their unique taste rather than as a significant part of the diet. However, the products made from Good-King-Henry leaves indicated that larger amounts could be consumed as the oxalate levels were reduced by dilution and processing.

Henry Fuseli’s Alternative Classicism
Directory of Open Access Journals (Sweden)
Martin Myrone
2015-12-01
Full Text Available The review considers Andrei Pop’s Antiquity, Theatre & The Painting of Henry Fuseli. This argues for the history painter and writer Fuseli as an exemplary ‘Neopagan’, a term coined by Pop to refer to the new sense of cultural pluralism and historical relativism which emerged in Europe after the discovery of the remains of Pompeii and Herculaneum in 1748. While this perspective offers a fresh view of the artist, relating him to the emergence of modernity, and illuminates some important aspects of his work, the reviewer also suggests that the monographic focus risks re-asserting a sense of Fuseli’s exceptionalism.

Problem-based learning in a health sciences librarianship course.
Dimitroff, A; Ancona, A M; Beman, S B; Dodge, A M; Hutchinson, K L; LaBonte, M J; Mays, T L; Simon, D T
1998-01-01
Problem-based learning (PBL) has been adopted by many medical schools in North America. Because problem solving, information seeking, and lifelong learning skills are central to the PBL curriculum, health sciences librarians have been actively involved in the PBL process at these medical schools. The introduction of PBL in a library and information science curriculum may be appropriate to consider at this time. PBL techniques have been incorporated into a health sciences librarianship course at the School of Library and Information Science (LIS) at the University of Wisconsin-Milwaukee to explore the use of this method in an advanced Library and Information Science course. After completion of the course, the use of PBL has been evaluated by the students and the instructor. The modified PBL course design is presented and the perceptions of the students and the instructor are discussed. PMID:9681169

HENRY H. CHEEK AND TRANSFORMISM: NEW LIGHT ON CHARLES DARWIN'S EDINBURGH BACKGROUND.
Jenkins, Bill
2015-06-20
Evidence for the transformist ideas espoused by Henry H. Cheek (1807-33), a contemporary of Charles Darwin's at the University of Edinburgh, sheds new light on the intellectual environment of Edinburgh in the late 1820s and early 1830s. Cheek was the author of several papers dealing with the transmutation of species influenced by the theories of Etienne Geoffroy Saint-Hilaire (1772-1844), Jean-Baptiste Lamarck (1744-1829) and the Comte de Buffon (1707-88). Some of these were read to student societies, others appeared in the Edinburgh Journal of Natural and Geographical Science, which Cheek edited between 1829 and 1831. His writings give us a valuable window onto some of the transformist theories that were circulating among Darwin's fellow medical students in the late 1820s, to which Darwin would have been exposed during his time in Edinburgh, and for which little other concrete evidence survives.

Full Text Available The book Rethinking Social Inquiry, edited by Henry E. BRADY and David COLLIER, is a response to a book by KING, KEOHANE and VERBA (1994 that aimed to introduce quantitative standards to qualitative research. The authors of the book reviewed here criticize many of the suggestions made there because they argue that qualitative research requires other tools. Nevertheless, they agree that the foundations of research design are similar. The book comprises a comprehensive critique of mainstream quantitative techniques, describes a set of qualitative tools for research, and addresses issues of how to combine qualitative and quantitative approaches to maximize analytical leverage. It is an excellent contribution to the methodological debate in the social sciences. URN: urn:nbn:de:0114-fqs0602309

In this study, the first aza-Henry reaction of nitriles with nitromethane in a CuI/Cs 2 CO 3 /DBU system is described. The process was conveniently and directly used for the synthesis of β-aminonitroalkenes 2a-x and tolerated aryl-, alkyl-, hetaryl-, alkenyl-, and alkynylnitriles. The resulting aminonitroalkenes 2 could be successfully transformed to the corresponding 2-nitroacetophenones, 2-amino-1-halonitroalkenes, 2-alkylaminonitroalkenes, or 3-nitropyridines. In the presence of H 2 O, the aza-Henry reaction turned the reaction path to the nitrile hydration to exclusively yield the amides 3a-s.

Henri Pirenne: Historian and Man of the World

How the Other Half Lives: Under the Arch with Lady Henry Somerset
Directory of Open Access Journals (Sweden)
Paisana Joanne
2017-10-01
Full Text Available The reforming work of Isabella Caroline Somerset (Lady Henry Somerset 1851-1921 is largely overlooked today. Dedicated to women’s causes at home and abroad and to temperance in particular, having first-hand knowledge of the privileged and the underprivileged, this determined, multi-talented and opinionated woman uncharacteristically wrote a fictional novel, Under the Arch (1906. In the novel, London aristocrats are portrayed rubbing shoulders with slum dwellers, but there is little real connection. The problems that the social policies introduced by the Liberals from 1906-1914 would address are nevertheless highlighted. It can be no coincidence that Somerset was well acquainted with many of these politicians. The themes of relieving the poor, Christian doctrine, marriage, women’s suffrage and imperialism are addressed, although Somerset’s focus is simply on “doing good” and loving one’s neighbour

Should bulk cloudwater or fogwater samples obey Henry's law
Energy Technology Data Exchange (ETDEWEB)
Pandis, S.N.; Seinfeld, J.H. (Department of Chemical Engineering and Environmental Quality Laboratory, California Institute of Technology, Pasadena, CA (USA))
1991-06-20
In this work we prove that mixing of droplets with different {ital p}H that are individually in Henry's law equilibrium with the surrounding atmosphere always results in a bulk mixture that is supersaturated with weak acids like S(IV) and HCOOH and bases like NH{sub 3} with respect to the original atmosphere. The degree of supersaturation of the bulk liquid water sample for a particular species depends on its dissociation constant, on the initial {ital p}H of the bulk droplet mixture, and on the distribution of the {ital p}H and of the liquid water over the droplet spectrum. High supersaturations result only when the {ital p}H of the bulk droplet mixture exceeds the {ital p}K{sub {ital a}} of the species, in which {ital p}H range large {ital p}H differences among droplets of different sizes lead to large deviations from Henry's law for the bulk mixture. The deviation is shown to depend on the ratio of the arithmetic mean to the harmonic mean of the hydrogen ion concentrations of the droplets with the liquid water content used was weighting factor in the calculation of the means. The theory developed can explain observed discrepancies from Henry's law in atmospheric samples and also other observed phenomena like the reported increase of {ital p}H values of bulk aqueous samples during storage. {copyright} American Geophysical Union 1991

Scientific and technological know-how, not the amount of natural resources, determines the development of a country. Bangladesh, with insignificant natural resources and a huge population on a small piece of land, can be developed through scientific and technological means. Whereas it was once the most sought-after subject at secondary and postsecondary levels, science is losing its appeal in an alarming shift of choice. Problems in science education and possible solutions for Bangladesh, which has limited resources for encouraging science education, are presented.

[Henri-Léonard Bertin and the development of agriculture in the Age of Enlightenment].
Pédro, Georges
2012-05-01
This meeting of the Committee on the History of Science and Epistemology takes place as we celebrate the 250th anniversary of the creation of the world's first veterinary schools, a major event among all those that, in the wake of the Physiocrat movement initiated by Quesnay and DuPont de Nemours, shaped the modernisation of agriculture in France during the 18th century. Henri-Léonard Bertin (1720-1792) was the impetus to the restructuring process. He was well aware that farming should not remain an activity that solely provides a livelihood for the population, but that it needed to be modernised, i.e. it should produce more, and better. His view was that agriculture could become a great source of riches for France and therefore, a true economic and even political force. He used the various official positions he occupied during that period (Intendant of Lyon (1754-1757), Controller General of Finances (1759-1763), Minister-Secretary of State for Agriculture (1763-1780) to initiate a number of reforms that brought about the modernisation of the kingdom's agricultural world.

The recent review of taxation in Australia - the Henry tax review - has recommended that the federal government increase the taxes already levied on tobacco and alcohol. Tobacco and alcohol taxes are put forward as the best way of reducing the social harms caused by the use and misuse of these substances. Junk foods have the same pattern of misuse and the same social costs as tobacco and alcohol. The Henry tax review rejects the idea of taxing fatty foods, and to date the government has not implemented a tax on junk food. We propose that a tax on junk food be implemented as a tool to reduce consumption and address the obesity epidemic.

Full Text Available Lyall H. Powers, in Henry James and the Naturalist Movement, dubs the period spanning from “The Art of Fiction” in 1884 to The Tragic Muse in 1890 Henry James’s “Naturalist Experiment”, and rightfully so (Powers 3. There is much evidence, in James’s own notebooks, that The Bostonians was influenced by Daudet’s L’Évangeliste, The Princess Casamassima by Turgeneff’s Virgin Soil, and The Tragic Muse by the narrative techniques of Maupassant (NB 47, Powers 91, NB 92, and Powers effectively show...

Staging Henry Fielding: The Author-Narrator in Tom Jones On Screen
Directory of Open Access Journals (Sweden)
Eli Løfaldli
2017-06-01
Full Text Available As recent adaptation theory has shown, classic-novel adaptation typically sets issues connected to authorship and literal and figurative ownership into play. This key feature of such adaptations is also central to the screen versions of Henry Fielding’s Tom Jones (1749. In much of Fielding’s fiction, the narrator, typically understood as an embodiment of Fielding himself, is a particularly prominent presence. The author-narrator in Tom Jones is no exception: not only is his presence strongly felt throughout the novel, but through a variety of means, ‘The History of Tom Jones, A Foundling’ is also distinctly marked as being under his control and ownership. The two adaptations of Fielding’s novel, a 1963 film and a 1997 television series, both retain the figure of the author-narrator, but differ greatly in their handling of this device and its consequent thematic ramifications. Although the 1963 film de-emphasises Henry Fielding’s status as proprietor of the story, the author-narrator as represented in the film’s voiceover commentary is a figure of authority and authorial control. In contrast, the 1997 adaptation emphasises Fielding’s ownership of the narrative and even includes the author-narrator as a character in the series, but this ownership is undermined by the irreverent treatment to which he is consistently subjected. The representations of Henry Fielding in the form of the author-narrator in both adaptations are not only indicative of shifting conceptions of authorship, but also of the important interplay between authorship, ownership and adaptation more generally.

In the fall of 1945, Secretary of Commerce Henry Wallace handpicked Edward Condon, a respected theoretical physicist, to become director of the National Bureau of Standards. Already regarded by many academic and industrial scientists as a second-rate research institution, the Bureau had deteriorated further during the Great Depression. An ardent New Dealer who favored government action to prevent anticompetitive behavior in the marketplace, Wallace claimed that giant corporations leveraged their extensive patent holdings and research capabilities to manipulate markets and restrict competition at the expense of smaller firms without similar resources. Through a revitalized Bureau of Standards, Wallace intended to mitigate monopolistic behavior among large companies by transforming the Department of Commerce into an effective clearinghouse for scientific research that would stimulate technological innovation in small businesses. The Bureau's postwar expansion, however, foundered on congressional efforts to dismantle the legacies of the New Deal, Condon's lack of commitment to the technical requirements of the small business community, and the intense competition for resources within an institutionally pluralist federal research establishment dominated by the exigencies of the Cold War. Without sufficient financial support from congressional appropriations committees, Condon turned to the military to fund new research programs at the Bureau of Standards. These programs, however, owed their institutional growth to the demands of the national security state, not to the fading influence of Henry Wallace's New Deal liberalism.

The last ride of Henry II of France: orbital injury and a king's demise.
Eftekhari, Kian; Choe, Christina H; Vagefi, M Reza; Eckstein, Lauren A
2015-01-01
Jousting was a popular pastime for royalty in the Renaissance era. Injuries were common, and the eye was particularly at risk from the splinters of the wooden lance. On June 30, 1559, Henry II of France participated in a jousting tournament to celebrate two royal weddings. In the third match, Gabriel de Montgomery struck Henry on the right shoulder and the lance splintered, sending wooden shards into his face and right orbit. Despite being cared for by the prominent physicians Ambroise Paré and Andreas Vesalius, the king died 10 days later and was found to have a cerebral abscess. The wound was not explored immediately after the injury; nevertheless, wooden foreign bodies were discovered in the orbit at the time of autopsy. The dura had not been violated, suggesting that an infection may have traveled from the orbit into the brain. Nostradamus and Luca Guarico, the astrologer to the Medici family, had prophesied the death of Henry II of France, but he ignored their warnings and thus changed the course of history in Renaissance Europe.

Let us keep observing and play in sand boxes (Henry Darcy Medal Lecture)
Illangasekare, T. H.
2012-04-01
Henry Darcy was a civil engineer recognized for a number of technical achievements and scientific discoveries. The sand column experiments for which he is known revealed the linear relationship that exists between fluid motion and driving forces at low velocities. Freeze and Back (1983) stated, ''The experiments carried out by Darcy with the help of his assistant, Ritter, in Dijon, France in 1855 and 1856 represent the beginning of groundwater hydrology as a quantitative science." Because of the prominence given to this experiment, two important facts behind Darcy's contributions to subsurface hydrology have not received much attention. First, Darcy was not only a good engineer, but he was also a highly respected scientist whose knowledge of both the fundamentals of fluid mechanics and the natural world of geology led to better conceptualizing and quantifying of groundwater processes at relevant scales to solve practical problems. The experiments for which he is known may have already been conceived, based on his theoretical understanding, and the results were anticipated (Brown 2002). Second, Darcy, through his contributions with Dupuit, showed that they understood hydrologeology at a regional scale and developed methods for quantification at the scale of geologic stratum (Ritz and Bobek, 2008). The primary thesis of this talk is that scientific contributions such as the one Darcy made require appreciation and a thorough understanding of fundamental theory coupled with observation and recording of phenomena both in nature and in the laboratory. Along with all of the significant theoretical, mathematical modeling, and computational advances we have made in the last several decades, laboratory experiments designed to observe phenomena and processes for better insight, accurate data generation, and hypothesis development are critically important to make scientific and engineering advances to address some of the emerging and societally important problems in hydrology

Preparing new nurses with complexity science and problem-based learning.
Hodges, Helen F
2011-01-01
Successful nurses function effectively with adaptability, improvability, and interconnectedness, and can see emerging and unpredictable complex problems. Preparing new nurses for complexity requires a significant change in prevalent but dated nursing education models for rising graduates. The science of complexity coupled with problem-based learning and peer review contributes a feasible framework for a constructivist learning environment to examine real-time systems data; explore uncertainty, inherent patterns, and ambiguity; and develop skills for unstructured problem solving. This article describes a pilot study of a problem-based learning strategy guided by principles of complexity science in a community clinical nursing course. Thirty-five senior nursing students participated during a 3-year period. Assessments included peer review, a final project paper, reflection, and a satisfaction survey. Results were higher than expected levels of student satisfaction, increased breadth and analysis of complex data, acknowledgment of community as complex adaptive systems, and overall higher level thinking skills than in previous years. 2011, SLACK Incorporated.

A strong science knowledge base and problem solving skills have always been highly valued for employment in the science industry. Skills currently needed for employment include being able to problem solve (Overtoom, 2000). Academia also recognizes the need for effectively teaching students to apply problem solving skills in clinical settings. This thesis investigates how students solve complex science problems in an academic setting in order to inform the development of problem solving skills for the workplace. Students' use of problem solving skills in the form of learned concepts and procedural knowledge was studied as students completed a problem that might come up in real life. Students were taking a community college sophomore biology course, Human Anatomy & Physiology II. The problem topic was negative feedback inhibition of the thyroid and parathyroid glands. The research questions answered were (1) How well do community college students use a complex of conceptual knowledge when solving a complex science problem? (2) What conceptual knowledge are community college students using correctly, incorrectly, or not using when solving a complex science problem? (3) What problem solving procedural knowledge are community college students using successfully, unsuccessfully, or not using when solving a complex science problem? From the whole class the high academic level participants performed at a mean of 72% correct on chapter test questions which was a low average to fair grade of C-. The middle and low academic participants both failed (F) the test questions (37% and 30% respectively); 29% (9/31) of the students show only a fair performance while 71% (22/31) fail. From the subset sample population of 2 students each from the high, middle, and low academic levels selected from the whole class 35% (8/23) of the concepts were used effectively, 22% (5/23) marginally, and 43% (10/23) poorly. Only 1 concept was used incorrectly by 3/6 of the students and identified as

This essay teases out the intimate connections between the scientific and fiscal realms in the context of American germ theory and obstetrics. By uncovering the economic and medical contexts of Henry James's Washington Square-set during the infancy of germ theory and the heyday of American obstetrics-this essay exposes a previously unexplored subtextual history of contagion in the text. Although this scientific history seems relegated to the novel's margins, understanding the changing scientific cosmologies and professional organizations in the context of the novel's setting and composition reveals that these tiny infectious particles and their vectors fundamentally shape the plot of the novel.

Teaching creativity and inventive problem solving in science.
DeHaan, Robert L
2009-01-01
Engaging learners in the excitement of science, helping them discover the value of evidence-based reasoning and higher-order cognitive skills, and teaching them to become creative problem solvers have long been goals of science education reformers. But the means to achieve these goals, especially methods to promote creative thinking in scientific problem solving, have not become widely known or used. In this essay, I review the evidence that creativity is not a single hard-to-measure property. The creative process can be explained by reference to increasingly well-understood cognitive skills such as cognitive flexibility and inhibitory control that are widely distributed in the population. I explore the relationship between creativity and the higher-order cognitive skills, review assessment methods, and describe several instructional strategies for enhancing creative problem solving in the college classroom. Evidence suggests that instruction to support the development of creativity requires inquiry-based teaching that includes explicit strategies to promote cognitive flexibility. Students need to be repeatedly reminded and shown how to be creative, to integrate material across subject areas, to question their own assumptions, and to imagine other viewpoints and possibilities. Further research is required to determine whether college students' learning will be enhanced by these measures.

Impact of problem finding on the quality of authentic open inquiry science research projects
Labanca, Frank
2008-11-01
Problem finding is a creative process whereby individuals develop original ideas for study. Secondary science students who successfully participate in authentic, novel, open inquiry studies must engage in problem finding to determine viable and suitable topics. This study examined problem finding strategies employed by students who successfully completed and presented the results of their open inquiry research at the 2007 Connecticut Science Fair and the 2007 International Science and Engineering Fair. A multicase qualitative study was framed through the lenses of creativity, inquiry strategies, and situated cognition learning theory. Data were triangulated by methods (interviews, document analysis, surveys) and sources (students, teachers, mentors, fair directors, documents). The data demonstrated that the quality of student projects was directly impacted by the quality of their problem finding. Effective problem finding was a result of students using resources from previous, specialized experiences. They had a positive self-concept and a temperament for both the creative and logical perspectives of science research. Successful problem finding was derived from an idiosyncratic, nonlinear, and flexible use and understanding of inquiry. Finally, problem finding was influenced and assisted by the community of practicing scientists, with whom the students had an exceptional ability to communicate effectively. As a result, there appears to be a juxtaposition of creative and logical/analytical thought for open inquiry that may not be present in other forms of inquiry. Instructional strategies are suggested for teachers of science research students to improve the quality of problem finding for their students and their subsequent research projects.

Henri Ellenberger, psychiatrist and historian, experienced a decisive period in his career in the early fifties of the last century. Educated in France, intern at Sainte-Anne Hospital, he was working in Switzerland after the war and then tried to move to the United States. It was during his participation in the French group "l'Evolution Psychiatrique" that he happened to contribute to the treatise of psychiatry (1955) of the French medical and surgical encyclopaedia ("EMC") and organise an observation trip to the United States. He was supported at that time by Henri Ey, key figure of French psychiatry. While going back to his career, we would like to emphasise on his comments about the "Psychotherapy of schizophrenia". Even though later Ellenberger became a well-known researcher in North America, it is more a question for us to discuss the scientific ambition he had in this particular context of a French learned society as a member of "l'Evolution Psychiatrique" and as a psychiatrist formerly intern from the "Hôpitaux psychiatriques de la Seine" (Parisian district).

[Problems of world outlook and methodology of science integration in biological studies].
Khododova, Iu D
1981-01-01
Problems of worldoutlook and methodology of the natural-science knowledge are considered basing on the analysis of tendencies in the development of the membrane theory of cell processes and the use of principles of biological membrane functioning when solving some scientific and applied problems pertaining to different branches of chemistry and biology. The notion scientific knowledge integration is defined as interpenetration of approaches, methods and ideas of different branches of knowledge and enrichment on this basis of their content resulting in knowledge augmentation in each field taken separately. These processes are accompanied by appearance of new branches of knowledge - sciences "on junction" and their subsequent differentiations. The analysis of some gnoseological situations shows that integration of sciences contributes to coordination and some agreement of thinking styles of different specialists, puts forward keen personality of a scientist demanding, in particular, his high professional mobility. Problems of scientific activity organization are considered, which involve social sciences into the integration processes. The role of philosophy in the integration processes is emphasized.

Henri Fayol’un Yönetim Düşüncesi Üzerine Notlar(Notes on Managerial Thought of Henry Fayol
Directory of Open Access Journals (Sweden)

2007-01-01
Full Text Available Henri Fayol, developed a managerial approach which is a perfect guide for both private and public sectors through focusing systematically upon managerial process. A major advantage of Fayol in creating a general managerial doctrine was his pratician side. His managerial thought which was developed in the early 20th century lasted up to our times. The distinguished characteristic of Fayol’s thought was studying the administrative reality through separating it into its functions, in that it helps to understand evolution and operation of organisations. The importance of his doctrine for today is that adapting contemporary managerial techniques into organisations of various kinds needs to refer Fayol’s managerial aproach in one way or another.

This is a slow process which in forty years, from an observation misunderstood by Abel Niepce to its interpretation by Frederick Soddy, through the experiments of Henri Becquerel and thanks to developments in other knowledge (electron, X-rays) has led to a scientific progress known under the term of radioactivity, name given by Marie Slodowska-Curie.

Henri Ellenberger (1905-1993) wrote the first French-language synthesis of transcultural psychiatry ("Ethno-psychiatrie") for the French Encyclopédie Médico-Chirurgicale in 1965. His work casts new light on the early development of transcultural psychiatry in relation to scientific communities and networks, particularly on the role of Georges Devereux (1908-1985). The Ellenberger archives offer the possibility of comparing published texts with archival ones to create a more nuanced account of the history of transcultural psychiatry, and notably of the psychological treatment of Native Americans. This paper examines some key moments in the intellectual trajectories of Devereux and Ellenberger, including Devereux's dispute with Ackerknecht, the careers of Devereux and Ellenberger as therapists at the Menninger Foundation (Topeka, Kansas) in the 1950s, and their respective positions in the research network developed by McGill University (Montreal, Quebec) with the newsletter Transcultural Research in Mental Health Problems Finally, I consider their ties to other important figures in this field as it transitioned from colonial medicine to academic medicine, including Roger Bastide (France), Henri Collomb and the Ortigues (France and Africa), as well as Eric Wittkower and Brian Murphy (Canada) and Alexander Leighton (United States and Canada). © The Author(s) 2016.

There is a rich tradition of writings about the foundation of psychology laboratories, particularly in the United States but also in France. Various documents exist concerning former German laboratories in American and French literature. But the most interesting French paper was certainly written by a young psychologist named Victor Henri (1872-1940) who was a close collaborator of Alfred Binet (1857-1911) in the 1890s. Visiting various psychology laboratories, he wrote, in 1893, a clear description of the laboratories of Wundt, G. E. Müller, Martius and Ebbinghaus. An English translation is given of Henri's paper and the historical importance of his contribution is here expounded by contrasting the German and French psychologies of the time.

Full Text Available In his otherwise excellent book, A History of Archaeological Thought, Trigger (1989: 156 makes only one passing reference in a half-sentence to the central figure in the development of Paleolithic prehistory in the first half of the 20th century -- and manages to get his name wrong, confusing Henri Breuil with his long-time, close colleague, Hugo Obenrnaie . Thirty years after his death, Breuil's role in the history of Old World prehistory required more serious consideration. He was a seminal figure not only in rock art studies, but also in the archaeology of at least France, Spain, England, Portugal, South Africa, and China.

"small problems, Big Trouble" (spBT) is an exhibition of artist Judith Waller's paintings accompanied by text panels written by Earth scientist Dr. James A. Brey and several science researchers and educators. The text panels' message is as much the focus of the show as the art--true interdisciplinarity! Waller and Brey's history of art and earth science collaborations include the successful exhibition "Layers: Places in Peril". New in spBT is extended collaboration with other scientists in order to create awareness of geoscience and other subjects (i.e. soil, parasites, dust, pollutants, invasive species, carbon, ground water contaminants, solar wind) small in scale which pose significant threats. The paintings are the size of a mirror, a symbol suggesting the problems depicted are those we increasingly need to face, noting our collective reflections of shared current and future reality. Naturalistic rendering and abstract form in the art helps reach a broad audience including those familiar with art and those familiar with science. The goal is that gallery visitors gain greater appreciation and understanding of both—and of the sober content of the show as a whole. "small problems, Big Trouble" premiers in Wisconsin April, 2015. As in previous collaborations, Waller and Brey actively utilize art and science (specifically geoscience) as an educational vehicle for active student learning. Planned are interdisciplinary university and area high school activities linked through spBT. The exhibition in a public gallery offers a means to enhance community awareness of and action on scientific issues through art's power to engage people on an emotional level. This AGU presentation includes a description of past Waller and Brey activities: incorporating art and earth science in lab and studio classrooms, producing gallery and museum exhibitions and delivering workshops and other presentations.

Staudigl, Michael
This essay explores the practical significance of Michel Henry's "material phenomenology." Commencing with an exposition of his most basic philosophical intuition, i.e., his insight that transcendental affectivity is the primordial mode of revelation of our selfhood, the essay then brings to light how this intuition also establishes our relation to both the world and others. Animated by a radical form of the phenomenological reduction, Henry's material phenomenology brackets the exterior world in a bid to reach the concrete interior transcendental experience at the base of all exteriority. The essay argues that this "counter reduction," designed as a practical orientation to the world, suspends all traditional parameters of onto(theo)logical individuation in order to rethink subjectivity in terms of its transcendental corporeality, i.e., in terms of the invisible display of "affective flesh." The development of this "metaphysics of the individual" anchors his "practical philosophy" as he developed it-under shifting accents-throughout his oeuvre. In particular, the essay brings into focus Henry's reflections on modernity, the industry of mass culture and their "barbaric" movements. The essay briefly puts these cultural and political areas of Henry's of thinking into contact with his late "theological turn," i.e., his Christological account of Life and the (inter)subjective self-realization to which it gives rise.

Two-Level Solutions to Exponentially Complex Problems in Glass Science
DEFF Research Database (Denmark)
Mauro, John C.; Smedskjær, Morten Mattrup
Glass poses an especially challenging problem for physicists. The key to making progress in theoretical glass science is to extract the key physics governing properties of practical interest. In this spirit, we discuss several two-level solutions to exponentially complex problems in glass science....... Topological constraint theory, originally developed by J.C. Phillips, is based on a two-level description of rigid and floppy modes in a glass network and can be used to derive quantitatively accurate and analytically solvable models for a variety of macroscopic properties. The temperature dependence...... that captures both primary and secondary relaxation modes. Such a model also offers the ability to calculate the distinguishability of particles during glass transition and relaxation processes. Two-level models can also be used to capture the distribution of various network-forming species in mixed...

Edward Henry Sieveking and the demise of essential epilepsy.
Bladin, Peter F
2008-04-01
Edward Henry Sieveking, eminent London physician of Victorian times, is best known as the speaker at the historic meeting at which the chairman, Sir Charles Locock, seem to overshadow him in announcing the introduction of bromide--the first effective anti-convulsant. But in fact Sieveking had announced a most important conceptual advance in epileptology--the demise of "essential epilepsy". In addition his book, published soon after and based upon his lecture, is an important historical resumé of Victorian era concepts and management of epilepsy. His important contributions to the understanding and management of this condition are discussed herein.

Henri Ey's neojacksonism and the psychopathology of disintegrated mind.
Farina, Benedetto; Ceccarelli, Maurizio; Di Giannantonio, Massimo
2005-01-01
The French psychiatrist Henri Ey developed his organo-dynamic theory of the mind function and consciousness 50 years ago incorporating Hughling Jackson's thinking, along with psychiatric and philosophical theorizations by Janet and Bergson. This model has not received the attention it deserved, but recent advances in neuroscience rekindled interest for Ey's theory. By overcoming the Cartesian mind-body dualism and treating the mind-body unit as an inseparable whole, this model opens the way for the integrated treatment of mental disorders. Ey's conceptualization of consciousness as being simultaneously both synchronous and diachronic anticipates current theories of consciousness (Damasio, Edelman, Mesulam).

The pre-eminent achievements of the English physician and physiologist Ernest Henry Starling were his quantitative explanation of the transcapillary transport of fluid, the discovery of the first hormone, secretin, and his formulation of the law of the heart. In some ways Starling was an outsider...... and he was the centre of several scientific and social controversies. However, throughout his life he stressed fundamental scientific attitudes and ideas with remarkable persistence and power, although also balance, and his scientific achievements have stood the test of time....

Full Text Available The emergence and development of science and technology has been critical in improving the lives of mankind. It helps mankind to cope with a number of manmade and natural challenges and disasters. Science cannot totally diminish the level of human dependency on nature; but, with the existing availability of natural resources, science has increased our productivity. However, science and technology can also have its own negative impacts on the natural environment. For the purpose of increasing productivity and satisfying human needs, humans have been egoistically exploiting nature but disregarding the effects of their activities on nature. Science has also been trying its level best to mitigate the negative effects that results from mankind’s exploitation of nature. However, science alone is incapable of solving all environmental problems. This desk research employs secondary sources of data, and argues that environmental ethics should come to the fore in order to address the gap left by science with regard to resolving environmental problems that mankind faces today.

Publicações póstumas de Henri Fayol: revisitando sua teoria administrativa.
Directory of Open Access Journals (Sweden)
Edson Miranda de Souza
2011-02-01
Full Text Available O engenheiro francês Henri Fayol (1841-1925 é usualmente apresentado aos estudantes de Administração como o Pai da Escola Clássica de Administração, o que demonstra uma representação limitada da amplitude de sua contribuição para a evolução do pensamento administrativo. Além disso, é frequentemente associado ao seu contemporâneo, o teórico norte-americano Frederick Taylor, sendo aos dois atribuída a defesa de um modelo autoritário de administração. Entretanto, recentemente, pesquisadores descobriram, através do exame de documentos raros e inéditos, um desconhecido retrato desse pioneiro. Este trabalho resulta de uma investigação que buscou levantar fontes de informação bibliográfica disponíveis, publicadas ou não, incluindo resultados de trabalhos de pesquisadores da França, dos Estados Unidos, do Canadá, da Austrália e do Japão. Esses pesquisadores compõem um reduzido grupo de estudiosos, aqui denominados “novos fayolistas” porque retomam, depois de anos de quase amnésia no meio acadêmico, o interesse pelas contribuições de Henri Fayol. Tais estudos revelam conceitos desenvolvidos por Fayol que antecipam aspectos de teorias e práticas da Administração que, somente mais tarde, seriam desenvolvidas, como a Escola de Relações Humanas, a Teoria Contingencial e o Planejamento Estratégico. Ao apresentar as recentes pesquisas sobre o homem e o teórico Henri Fayol, este estudo permite, aos docentes e estudantes de língua portuguesa, acesso a escritos e palestras de sua autoria que, até então, permaneciam desconhecidos.

Full Text Available Crust-derived helium is generated from the radioactive decay of uranium, thorium and other radioactive elements in geological bodies. Compared with conventional natural gas, helium is a typical weak source gas as a result of extremely slow generation rate and absence of helium-generating peak. It is associated with methane or carbon dioxide reservoirs frequently and related to groundwater closely. Helium can meet the industry standard with 0.1% in volume fraction. In order to study the accumulation mechanism of helium, the previous research on Henry's coefficient and solubility of helium, nitrogen and methane are summarized and the key roles of Henry's Law in the helium migration, accumulation and preservation are discussed by simulating calculation taking Weihe Basin as an example. According to the Law, the gas solubility in dilute solution is controlled by the gas partial pressure and the Henry's coefficient. Compared with the carrier gases, the Henry's constant of helium is high, with striking difference at low and high temperature. In addition, the helium partial pressure is greatly different in helium source rocks and gas reservoirs, resulting in the great differences of helium solubility in the two places. The accumulation progresses are as follows. Firstly, helium can dissolve into water and migrate out of helium source rocks due to the high helium solubility, which is caused by high helium partial pressure and high temperature in source rock. Secondly, when dissolved helium is transported to the shallow gas reservoir, it is prone to be out of solution and into reservoir due to the extremely low partial pressure and low temperature. Meanwhile part of carrier gases dissolves into water, as if helium is “replaced” out. Furthermore, the low concentration funnel of dissolved helium is formed near the gas reservoir, then other dissolved helium continues to migrate towards the gas reservoir, which greatly improves the helium accumulation

Seeking a rapprochement between anthropology and the cognitive sciences: a problem-driven approach.
Whitehouse, Harvey; Cohen, Emma
2012-07-01
Beller, Bender, and Medin question the necessity of including social anthropology within the cognitive sciences. We argue that there is great scope for fruitful rapprochement while agreeing that there are obstacles (even if we might wish to debate some of those specifically identified by Beller and colleagues). We frame the general problem differently, however: not in terms of the problem of reconciling disciplines and research cultures, but rather in terms of the prospects for collaborative deployment of expertise (methodological and theoretical) in problem-driven research. For the purposes of illustration, our focus in this article is on the evolution of cooperation. Copyright © 2012 Cognitive Science Society, Inc.

Staging Henry Fielding: The Author-Narrator in Tom Jones On Screen
Løfaldli, Eli
2017-01-01
As recent adaptation theory has shown, classic-novel adaptation typically sets issues connected to authorship and literal and figurative ownership into play. This key feature of such adaptations is also central to the screen versions of Henry Fielding’s Tom Jones (1749). In much of Fielding’s fiction, the narrator, typically understood as an embodiment of Fielding himself, is a particularly prominent presence. The author-narrator in Tom Jones is no exception: not only is his presence strongly...

DNA-Catalyzed Henry Reaction in Pure Water and the Striking Influence of Organic Buffer Systems
Directory of Open Access Journals (Sweden)
Marleen Häring
2015-03-01
Full Text Available In this manuscript we report a critical evaluation of the ability of natural DNA to mediate the nitroaldol (Henry reaction at physiological temperature in pure water. Under these conditions, no background reaction took place (i.e., control experiment without DNA. Both heteroaromatic aldehydes (e.g., 2-pyridinecarboxaldehyde and aromatic aldehydes bearing strong or moderate electron-withdrawing groups reacted satisfactorily with nitromethane obeying first order kinetics and affording the corresponding β-nitroalcohols in good yields within 24 h. In contrast, aliphatic aldehydes and aromatic aldehydes having electron-donating groups either did not react or were poorly converted. Moreover, we discovered that a number of metal-free organic buffers efficiently promote the Henry reaction when they were used as reaction media without adding external catalysts. This constitutes an important observation because the influence of organic buffers in chemical processes has been traditionally underestimated.

Beyond the Historical Record? Henry James in “The Master at St. Bartholomew’s Hospital
Directory of Open Access Journals (Sweden)
Elena Ogliari
2018-02-01
Full Text Available The article analyses the short-story “The Master at St Bartholomew’s Hospital 1914–1916” by Joyce Carol Oates (2007 in the broader context of the Jamesian biofiction, a series of novels and tales featuring Henry James as their protagonist. The addition of the prefix “bio-” to “fiction” points out the hybrid nature of these texts, which are a melange of biography, autobiography, criticism and fiction. Oates’s story not only epitomizes this hybridity, but it also proves to be an exploration of the potentiality of this subgenre to penetrate the mystery surrounding James’s persona and saturate the lacunae in his biography by resorting to what David Lodge defined as “the novelist’s licence”. The short-story is yet another evidence of Oates’s fascination with the unsaid in James’s life and prose, because it revolves around the silence into which he sank at the outbreak of the Great War, when he did not write anything in his pocket diaries for three months. In an attempt to go beyond the limits of the historical record, Oates gives insights into the mind of the author by depicting a Henry James in crisis – nagged by doubts about his artistic legacy – in an atmosphere of uncertainty enhanced by a complex intertextual play. The result is ‘a Henry James’ slightly divergent from the historical one: thus, the tale advocates the inaccessibility of the private life of a real individual. Nonetheless, the acknowledgement of this limit spurs the celebration of fictional imagination.

Despite the clinical importance of ruminal acidosis, ruminal buffering continues to be poorly understood. In particular, the constants for the dissociation of H2CO3 and the solubility of CO2 (Henry's constant) have never been stringently determined for ruminal fluid. The pH was measured in parallel directly in the rumen and the reticulum in vivo, and in samples obtained via aspiration from 10 fistulated cows on hay- or concentrate-based diets. The equilibrium constants of the bicarbonate system were measured at 38°C both using the Astrup technique and a newly developed method with titration at 2 levels of partial pressure of CO2 (pCO2; 4.75 and 94.98 kPa), yielding mean values of 0.234 ± 0.005 mmol ∙ L(-1) ∙ kPa(-1) and 6.11 ± 0.02 for Henry's constant and the dissociation constant, respectively (n/n = 31/10). Both reticular pH and the pH of samples measured after removal were more alkalic than those measured in vivo in the rumen (by ΔpH = 0.87 ± 0.04 and 0.26 ± 0.04). The amount of acid or base required to shift the pH of ruminal samples to 6.4 or 5.8 (base excess) differed between the 2 feeding groups. Experimental results are compared with the mathematical predictions of an open 2-buffer Henderson-Hasselbalch equilibrium model. Because pCO2 has pronounced effects on ruminal pH and can decrease rapidly in samples removed from the rumen, introduction of a generally accepted protocol for determining the acid-base status of ruminal fluid with standard levels of pCO2 and measurement of base excess in addition to pH should be considered.

Henri Fayol. Performativity of his ideas and oblivion of their creator
Dumez , Hervé
2018-01-01
Henri Fayol formulated one of the first theories of management and allows us to see how one of the first scientific approaches of management could or could not perform management practices. Therefore, Fayol is particularly interesting from the point of view of performativity (Callon, 1998, 2007, MacKenzie et al., 2007, Muniesa, 2014). The case is all the richer because it presents the rare characteristic of a direct confrontation between two rival theories, his and Taylor's, at the level of t...

Do natural science experiments influence public attitudes towards environmental problems?
International Nuclear Information System (INIS)
Wallner, A.; Hunziker, M.; Kienast, F.
2003-01-01
We investigated the significance of risk assessment studies in the public discussion on CO 2 emissions. Politicians and representatives from the public were interviewed by using the social-science technique of qualitative in-depth interviews. Three different types of attitudes towards natural science were found among politicians. Depending on which attitude a politician holds, risk assessment studies can have an impact on his/her readiness to support environmental policy measures. Regarding lay people, key factors affecting the acceptance of environmental policy measures are knowledge of environmental problems, their impacts on ecosystems or human health as well as direct personal perception of those impacts. Since direct perception is not always possible in everyday life, natural science experiments might be a means for successfully mediating this lacking perception. (author)

The trace of Henri Moissan's pioneer work 100 years ago is clearly evidenced by an overview of achievements in high temperature devices; 1987: "Le four électrique" by Henri Moissan; 1948-1952: "High temperature heating in a cavity rotary kiln using focusing of solar radiation" by Félix Trombe; 1962: "The cavity rotary kiln using focused solar radiation jointly with a plasma gun" by Marc Foëx; 1970: "The rotary kiln with two plasma guns and arc transfer" by Marc Foëx; 1984: "The plasma furnace" by Electricité de France (EDF) at Renardières; 1997: "The plasma furnace" by the Atomic Energy Center (CEA) at Cadarache, the VULCANO program. The first part of this contribution is devoted to Henri Moissan. Re-reading his early book on the electric furnace, especially the first chapter and the sections on silica, carbon vapor and experiments performed in casting molten metal--the conclusions are outstanding--provides modern readers with an amazing insight into future developments. The last two parts are devoted to Félix Trombe and Marc Foëx, tracing the evolution of high temperature cavity processus leading to the solar furnace and the present day plasma furnace at the CEA. Focus is placed on research conducted by the French National Center for Scientific Research (CNRS) with the solar and plasma furnaces at Odeillo. The relationships with Henri Moissan's early work are amazing, offering a well deserved homage to this pioneer researcher.

Energy Technology Data Exchange (ETDEWEB)
Cerofolini, G F
1977-01-01
A unified description of adsorption on real surfaces from the Henry Range to the formation of the liquid layer was developed on the basis of the BET theory and the assumption that sites on real surfaces are not energetically homogeneous. The model describes the successive Henry, Dubinin-Radushkevich, Freundlich, and multilayer BET behavior of the adsorbed phase as the pressure increases. An analysis of isotherms over the whole coverage range showed that the heterogeneous surface character decreases with increasing number of adsorbed layers; that adsorption into the first and higher layers may be competitive, which produces a new isotherm resembling a mixed type II and III isotherm as proposed by Cerofolini and coworkers.

Henri Lopès : d’Une Quête Incessante à une identité plurielle
Directory of Open Access Journals (Sweden)
Vincent Simédoh
2006-04-01
Full Text Available Dans plusieurs oeuvres d’Henri Lopès, les personnages sont constamment en quête d’une identité. Une quête qu’ils entament comme un parcours puisque désormais ils vivent au confluent de plusieurs cultures et ils se sentent comme en exil. Ce n’est pas forcément un exil extérieur parce qu’ils ont quitté leur pays d’origine mais c’est plutôt un exil intérieur. Ainsi les personnages se sentent incapables de se situer par rapport à eux-mêmes et à autrui. Dès lors surgit une tentation, celle de se réfugier dans le souvenir qui n’existe même plus. La mémoire s’estompe. L’histoire elle-même fuit et disparaît. Ce qui fait naître chez les personnages un vide qui conduit à un malaise identitaire, d’où déchirement. En face de cet écartèlement, surgit une multitude de pistes. Et c’est dans cette perspective qu’Henri Lopès propose une identité plurielle.

Plans of mice and men: from bench science to science policy.
Simon, Ian D
2011-09-01
The transition from bench science to science policy is not always a smooth one, and my journey stretched as far as the unemployment line to the hallowed halls of the U.S. Capitol. While earning my doctorate in microbiology, I found myself more interested in my political activities than my experiments. Thus, my science policy career aspirations were born from merging my love of science with my interest in policy and politics. After receiving my doctorate, I accepted the Henry Luce Scholarship, which allowed me to live in South Korea for 1 year and delve into the field of science policy research. This introduction into science policy occurred at the South Korean think tank called the Science and Technology Policy Institute (STEPI). During that year, I used textbooks, colleagues, and hands-on research projects as my educational introduction into the social science of science and technology decision-making. However, upon returning to the United States during one of the worst job markets in nearly 80 years, securing a position in science policy proved to be very difficult, and I was unemployed for five months. Ultimately, it took more than a year from the end of the Luce Scholarship to obtain my next science policy position with the American Society for Microbiology Congressional Fellowship. This fellowship gave me the opportunity to work as the science and public health advisor to U.S. Senator Harry Reid. While there were significant challenges during my transition from the laboratory to science policy, those challenges made me tougher, more appreciative, and more prepared to move from working at the bench to working in the field of science policy.

Educational Technologies in Problem-Based Learning in Health Sciences Education: A Systematic Review
Jin, Jun
2014-01-01
Background As a modern pedagogical philosophy, problem-based learning (PBL) is increasingly being recognized as a major research area in student learning and pedagogical innovation in health sciences education. A new area of research interest has been the role of emerging educational technologies in PBL. Although this field is growing, no systematic reviews of studies of the usage and effects of educational technologies in PBL in health sciences education have been conducted to date. Objective The aim of this paper is to review new and emerging educational technologies in problem-based curricula, with a specific focus on 3 cognate clinical disciplines: medicine, dentistry, and speech and hearing sciences. Analysis of the studies reviewed focused on the effects of educational technologies in PBL contexts while addressing the particular issue of scaffolding of student learning. Methods A comprehensive computerized database search of full-text articles published in English from 1996 to 2014 was carried out using 3 databases: ProQuest, Scopus, and EBSCOhost. Eligibility criteria for selection of studies for review were also determined in light of the population, intervention, comparison, and outcomes (PICO) guidelines. The population was limited to postsecondary education, specifically in dentistry, medicine, and speech and hearing sciences, in which PBL was the key educational pedagogy and curriculum design. Three types of educational technologies were identified as interventions used to support student inquiry: learning software and digital learning objects; interactive whiteboards (IWBs) and plasma screens; and learning management systems (LMSs). Results Of 470 studies, 28 were selected for analysis. Most studies examined the effects of learning software and digital learning objects (n=20) with integration of IWB (n=5) and LMS (n=3) for PBL receiving relatively less attention. The educational technologies examined in these studies were seen as potentially fit for

Reproducibility of Psychological Experiments as a Problem of Post-Nonclassical Science
Directory of Open Access Journals (Sweden)
Vachkov I.V.,
2016-04-01
Full Text Available A fundamental project on reproducibility carried out in the USA by Brian Nosek in 2015 (the Reproducibility Project revealed a serious methodological problem in psychology: the issue of replication of psycho- logical experiments. Reproducibility has been traditionally perceived as one of the basic principles of the scientific method. However, methodological analysis of the modern post-nonclassical stage in the development of science suggests that this might be a bit too uncompromising as applied to psychology. It seems that the very criteria of scientific research need to be reconsidered with regard to the specifics of post-nonclassical science, and, as the authors put it, as a result, reproducibility might lose its key status or even be excluded at all. The reviewed problem and the proposed ways of coping with it are of high importance to research and practice in psychology as they define the strategies for organizing, conducting and evaluating experimental research.

Restauration de la statue de Henri IV
Directory of Open Access Journals (Sweden)
Stéphanie Celle
2012-04-01
Full Text Available Cette intervention de conservation du bronze de la statue de Henri IV était la première depuis sa création en 1818 : on héritait de la surface originale de l’œuvre altérée par les vicissitudes du temps et les événements historiques traversés. Le protocole de conservation se voulait respectueux de cette authenticité de la patine et a cherché à en laisser les marques tout en apportant une réponse pour contrer la corrosion active de l’alliage. C’est en conformité aux principes de conservation établis par Cesare Brandi, qu’ont été définis le nettoyage sélectif des surfaces et l’application de couches protectives sur le bronze. Par ailleurs, le moment du chantier est un moment privilégié pour observer un monument et mieux connaître son histoire particulière. Ce chantier nous a permis de redécouvrir deux ensembles de boîtes déposées dans l’antre du cheval dans des situations parfois surprenantes.This conservation treatment for the bronze statue of Henri IV is the first since its creation in 1818. While the original surface of the work remains, it has been altered by natural and human forces; including the weathering of the material from exposure to the elements and damage caused by historic events. The conservation protocol is respectful of this authenticity of the surface patina and the marks of damage due to historical events, while developing a treatment plan to counter the active corrosion of the alloy. In keeping with the principles of conservation established by Cesare Brandi, the treatment program defines the selective cleaning of the surface and the application of several layers of a protective coating on the bronze. In addition, the conservation project is an opportunity to carefully study a monument to better understand its unique history. This project allowed us to rediscover two sets of boxes placed inside the cavity of the horse; an unxpected discovery.

Some geomedical problems in relation to soil science
International Nuclear Information System (INIS)
Laag, J.
1988-01-01
Geomedicine may be defined as the science dealing with the influence of ordinary environmental factors on geographical distribution of health problems in man and animals. An important group of geomedical problems is connected to nutrition. These problems may either be caused by deficiency or surplus of certain matters. Many questions concerning the pollution of nature are classified under the latter group Radioactive pollutants are regarded as important special occurrences under this group. In order to be able to solve complicated geomedical problems, knowledge is needed on the circulation processes rocks-soils-water-plants-animals-man, and waste products back to the soils. The registration of locations of different radioactive elements can give basic material for special geomedical conclusions. Many chemical reactions in which radioactive matter are involved, depend on properties of the soils. Humus and clay minerals have, generally speaking, a high capacity for the absorbtion of soluble matter, but great variations occur. The reactions of radioactive isotopes supplied from the atmosphere, depend on properties of the soil. Radioactive substances are leached relatively rapidly from a soil with low absorption capacity, and may thus be taken away from the circulation in which terrestrial plants, animals and man take part. If the substances is strongly absorbed (fixed), they can also to some extent be withdrawn from the circulation processes

Problem- and case-based learning in science: an introduction to distinctions, values, and outcomes.
Allchin, Douglas
2013-01-01
Case-based learning and problem-based learning have demonstrated great promise in reforming science education. Yet an instructor, in newly considering this suite of interrelated pedagogical strategies, faces a number of important instructional choices. Different features and their related values and learning outcomes are profiled here, including: the level of student autonomy; instructional focus on content, skills development, or nature-of-science understanding; the role of history, or known outcomes; scope, clarity, and authenticity of problems provided to students; extent of collaboration; complexity, in terms of number of interpretive perspectives; and, perhaps most importantly, the role of applying versus generating knowledge.

The Pitfalls of a Tool-based Science and the Promise of a Problem-focused Science
Directory of Open Access Journals (Sweden)
Patrick E. McKnight
2011-05-01
Full Text Available Our present social sciences are at risk of losing sight of their primary purpose: the goal of reducing uncertainty. For years social scientists have drifted slowly toward the routine of employing of accepted methodological, conceptual, and analytical tools rather than engaging in problem oriented inquiry. Scientific contributions are reviewed in accordance to their compliance with the routine application of tools rather than focusing on their ability to problem-solve for a wider population. Researchers in every area of psychology for instance now insist on using methods such as random assignment and control groups, as well as data analytic procedures such as null hypothesis significance testing without regard to their relevance. A problem-focused inquiry would not dictate the routine use of any particular tool but rather the judicious application of tools when deemed appropriate. The following article describes the current situation in the framework contrasting toolbased and problem-focused inquiry and offers several insights that may create a more balanced and fruitful approach to scientific inquiry.

Victor Henri: 111 years of his equation.
Cornish-Bowden, Athel; Mazat, Jean-Pierre; Nicolas, Serge
2014-12-01
Victor Henri's great contribution to the understanding of enzyme kinetics and mechanism is not always given the credit that it deserves. In addition, his earlier work in experimental psychology is totally unknown to biochemists, and his later work in spectroscopy and photobiology almost equally so. Applying great rigour to his analysis he succeeded in obtaining a model of enzyme action that explained all of the observations available to him, and he showed why the considerable amount of work done in the preceding decade had not led to understanding. His view was that only physical chemistry could explain the behaviour of enzymes, and that models should be judged in accordance with their capacity not only to explain previously known facts but also to predict new observations against which they could be tested. The kinetic equation usually attributed to Michaelis and Menten was in reality due to him. His thesis of 1903 is now available in English.

This quantitative study examined science interest and achievement of middle school minority females in both traditional science classes and Problem-based Learning (PBL) science classes. The purpose of this study was to determine if there is a significant difference between traditional teaching and the PBL teaching method. The researcher also looked for a significant relationship between interest in science and achievement in science. This study used survey data from parents of female middle school science students to measure student interest in science concepts. The population of interest for this study was 13--15 year old eighth grade females from various racial make-ups such as, African American, Hispanic, Bi-racial, Asian, and Other Pacific Islander. Student achievement data was retrieved from the 8th grade science fall common assessed benchmark exam of both test groups. The results of the survey along with the benchmark data was to shed light on the way adolescent females learn and come to embrace science. The findings may provide guidance for science educators seeking to reach their minority female students and guide their achievement levels higher than before. From the results of the t-test and Pearson correlation test of this study, it can be concluded that while this study did not show a significant difference in academic achievement or interest between the two teaching styles, it revealed that interest in science has a positive role to play in the academic success of minority girls in science. The practical implications for examining these issues are to further the research on solutions for closing the minority and gender achievement gaps. The results of this study have implications for researchers as well as practitioners in the field of education.

The Problems of Realizing the Innovative Potential of Science and Mechanisms for their Solution
Directory of Open Access Journals (Sweden)
Ianchenko Zinayida B.
2017-06-01
Full Text Available The aim of the article is revealing reasons for the low payoff of science in terms of the effectiveness of the research activity and demand for its results in economic spheres, identifying problems in the innovation activity of research institutions and reasons for their arising, searching for fundamental approaches to the development of a strategy and mechanisms for realization of the innovative potential of science to strengthen its position in the real sector. The study used general scientific methods, including: systems approach — to systematize the problems of the innovation activity of research institutions; methods of theoretical generalization — to study the theoretical principles of the scientific and innovation activity; methods of analysis and synthesis — to search for fundamental approaches to the development of mechanisms for realization of the innovative potential of science. The used concepts of scientific activity and innovations are generalized. The author’s definition of the term “innovation” is proposed. The main reasons of the minor impact of science on the economy are systematized, the mechanisms for their elimination are offered. Based on the comprehensive analysis of the reasons for losing by science its impact on the economy, the ways of realizing the innovative potential of science are improved. The results of the research can be used in reforming domestic scientific research institutions.

(Mis)understanding Science: The Problem with Scientific Breakthroughs.
Evans, James P
2016-09-01
On Saturday morning, February 28, 1953, the mystery of heredity appeared secure. Humans hadn't the faintest idea of how genetic information was transmitted-how the uncanny resemblance between mother and daughter, grandfather and grandson was conveyed across generations. Yet, by that Saturday afternoon, two individuals, James Watson and Francis Crick, had glimpsed the solution to these mysteries. The story of Watson and Crick's great triumph has been told and retold and has rightly entered the pantheon of scientific legend. But Watson and Crick's breakthrough was just that: a rupture and dramatic discontinuity in human knowledge that solved a deep mystery, the likes of which occurs, perhaps, a couple of times each century. And that's the problem. The story is just so good and so irresistible that it has misled generations of scientists about what to expect regarding a life in science. And more damaging, the resulting breakthrough mentality misleads the public, the media, and society's decision-makers about how science really works, all to the detriment of scientific progress and our society's well-being. © 2016 The Hastings Center.

Since some 20 years most Dutch universities have one or more science shops. Central shops handle research questions for all disciplines. Specialized shops are part of a department of chemistry or medicine, history, social science, etc. The shops have evolved rather differently, but their main mission still is to help social groups that lack money and have no easy access to scientific knowledge, e.g. neighbourhood, environmental, third world or patient groups. Most also help non-commercial organizations such as schools, trade unions or local authorities. Low-cost help can be provided because students do the work as part of their training, mainly in student projects (literature search, practical work, graduation, etc.). A total staff of 80, helped by 600 students, 250 voluntary and 50 paid researchers, handle 1500 questions resulting in 300 reports (estimated figures 1995). Science shops for physics (`Physics Shop', PS) have to deal with practical problems, generally involving classical physics. Major topics are noise, vibration, radiation, indoor climate and energy: most of the work lies in estimating/measuring relevant parameters, assessing impact, seeking solutions. The 3 Dutch PS's have developed in different directions. One is run entirely by students and deals with small, concrete problems. The second PS is managed by a co-ordinator who mediates between client groups and physics staff members who assist students in small and larger projects. The third has a lot of in-house expertise, and the shop staff is in direct contact with client groups as well as students who work in the PS itself. In questions submitted to the PS it is not always immediately clear what to do or how to do it because of the non-scientific phrasing of the problems and problems include non-physical (e.g. technical, health or legal) aspects. Also, difficulties in solving the problems are typically not in the underlying physics, but in the lack of accurate data and of control of the complex

Science and Society - Problems, issues and dilemmas in science education
2001-01-01
Next in CERN's series of Science and Society speakers is Jonathan Osborne, Senior Lecturer in Science Education at King's College London. On Thursday 26 April, Dr Osborne will speak in the CERN main auditorium about current issues in science education in the light of an ever more science-based society. Jonathan Osborne, Senior Lecturer in Science Education at King's College London. Does science deserve a place at the curriculum high table of each student or is it just a gateway to a set of limited career options in science and technology? This question leads us to an important change in our ideas of what science education has been so far and what it must be. Basic knowledge of science and technology has traditionally been considered as just a starting point for those who wanted to build up a career in scientific research. But nowadays, the processes of science, the analysis of risks and benefits, and a knowledge of the social practices of science are necessary for every citizen. This new way of looking at s...

Thinking in time an introduction to Henri Bergson
Guerlac, Suzanne
2006-01-01
"In recent years, we have grown accustomed to philosophical language that is intensely self-conscious and rhetorically thick, often tragic in tone. It is enlivening to read Bergson, who exerts so little rhetorical pressure while exacting such a substantial effort of thought. . . . Bergson's texts teach the reader to let go of entrenched intellectual habits and to begin to think differently—to think in time. . . . Too much and too little have been said about Bergson. Too much, because of the various appropriations of his thought. Too little, because the work itself has not been carefully studied in recent decades."—from Thinking in TimeHenri Bergson (1859–1941), whose philosophical works emphasized motion, time, and change, won the Nobel Prize for Literature in 1927. His work remains influential, particularly in the realms of philosophy, cultural studies, and new media studies. In Thinking in Time, Suzanne Guerlac provides readers with the conceptual and contextual tools necessary for informed appreciati...

Competence of matric physical science teachers in some basic problem-solving strategies
Directory of Open Access Journals (Sweden)
Mailoo Selvaratnam
2011-01-01
Full Text Available The National Curriculum Statement for matric physical science places strong emphasis on the development of critical thinking and reasoning abilities of pupils. The successful implementation of this curriculum therefore requires teachers who are competent in the cognitive (intellectual skills and strategies needed for learning science effectively. Testing of teachers’ competence in this aspect is therefore important. I therefore analysed teachers’ answers to questions that were carefully designed to test competence in some basic intellectual strategies that are important for problem solving in physical science courses. A total of 73 matric physical science teachers, from about 50 Dinaledi schools in the North West and KwaZulu-Natal provinces in South Africa, were tested in five intellectual strategies: clear representation of problems, identifying and focusing on the goal, identification and use of relevant principles, use of equations for deductions and proceeding step-by-step with the solution. The teachers’ competence was poor in all the intellectual strategies tested. About 60% (the average performance in all 13 questions used for testing of teachers tested were unable to solve the questions correctly. An important objective of the curriculum is the development of critical thinking, scientific reasoning and strategies of pupils. This study shows that the achievement of this objective will be seriously handicapped because of the lack of competence of many teachers in intellectual strategies. There is therefore a need to train teachers in order to increase their competence in this aspect.

Energy Technology Data Exchange (ETDEWEB)
Huesemann, Michael H.(BATTELLE (PACIFIC NW LAB))
2000-12-01
It is currently believed that science and technology can provide effective solutions to most, if not all, environmental problems facing western industrial societies. The validity of this optimistic assumption is highly questionable for at least three reasons: First, current mechanistic, reductionist science is inherently incapable of providing the complete and accurate information which is required to successfully address environmental problems. Second, both the conservation of mass principle and the second law of thermodynamics dictate that most remediation technologies - while successful in solving specific pollution problems - cause unavoidable negative environmental impacts elsewhere or in the future. Third, it is intrinsically impossible to design industrial processes that have no negative environmental impacts. This follows not only from the entropy law but also from the fact that any generation of energy is impossible without negative environmental consequences. It can therefore be concluded that science and technology have only very limited potential in solving current and future environmental problems. Consequently, it will be necessary to address the root cause of environmental deterioration, namely the prevailing materialistic values that are the main driving force for both overpopulation and overconsumption. The long-term protection of the environment is therefore not primarily a technical problem but rather a social and moral problem that can only be solved by drastically reducing the strong influence of materialistic values.

Given low course enrollment in geoscience courses, retention in undergraduate geoscience courses, and granting of BA and advanced degrees in the Earth sciences an effective strategy to increase participation in this field is necessary. In response, as K-12 education is a conduit to college education and the future workforce, Earth science education at the K-12 level was targeted with the development of teacher professional development around Earth system science, inquiry and problem-based learning. An NSF, NOAA and NASA funded effort through the Institute for Global Environmental Strategies led to the development of the Earth System Science Educational Alliance (ESSEA) and dissemination of interdisciplinary Earth science content modules accessible to the public and educators. These modules formed the basis for two teacher workshops, two graduate level courses for in-service teachers and two university course for undergraduate teacher candidates. Data from all three models will be presented with emphasis on the teacher workshop. Essential components of the workshop model include: teaching and modeling Earth system science analysis; teacher development of interdisciplinary, problem-based academic units for implementation in the classroom; teacher collaboration; daily workshop evaluations; classroom observations; follow-up collaborative meetings/think tanks; and the building of an on-line professional community for continued communication and exchange of best practices. Preliminary data indicate increased understanding of Earth system science, proficiency with Earth system science analysis, and renewed interest in innovative delivery of content amongst teachers. Teacher-participants reported increased student engagement in learning with the implementation of problem-based investigations in Earth science and Earth system science thinking in the classroom, however, increased enthusiasm of the teacher acted as a contributing factor.

Poincaré and the three body problem
Barrow-Green, June
1997-01-01
The idea of chaos figures prominently in mathematics today. It arose in the work of one of the greatest mathematicians of the late 19th century, Henri Poincaré, on a problem in celestial mechanics: the three body problem. This ancient problem-to describe the paths of three bodies in mutual gravitational interaction-is one of those which is simple to pose but impossible to solve precisely. Poincaré's famous memoir on the three body problem arose from his entry in the competition celebrating the 60th birthday of King Oscar of Sweden and Norway. His essay won the prize and was set up in print as a paper in Acta Mathematica when it was found to contain a deep and critical error. In correcting this error Poincaré discovered mathematical chaos, as is now clear from Barrow-Green's pioneering study of a copy of the original memoir annotated by Poincaré himself, recently discovered in the Institut Mittag-Leffler in Stockholm. Poincaré and the Three Body Problem opens with a discussion of the development of the th...

From 2012 to 2016, the integrated laboratories of the Henry Ford Health System used a quality technical team to develop and improve a management subsystem designed to identify, track, trend, and summarize nonconformances based on frequency, risk, and root cause for elimination at the level of the work. Programmatic improvements and training resulted in markedly increased documentation culminating in 71,641 deviations in 2016 classified by a taxonomy of 281 defect types into preanalytic (74.8%), analytic (23.6%), and postanalytic (1.6%) testing phases. The top 10 deviations accounted for 55,843 (78%) of the total. Deviation management is a key subsystem of managers' standard work whereby knowledge of nonconformities assists in directing corrective actions and continuous improvements that promote consistent execution and higher levels of performance. © American Society for Clinical Pathology, 2017.

Jean-Baptiste Dussert
2012-12-01
Full Text Available Although the author of four novels, Michel Henry never produced an aesthetics of literature. The purpose of this article is, after a presentation of his philosophy of immanence and his concept of life, to locate where the literary practice takes place in his system. In this study, we are not interested in the poetic quality of his works, but in the possibility to base his singular creativity on his philosophical reflection. This leads us to insert literature in the vast phenomenon of culture and ethics, and to grasp the function of poetics in the struggle against barbarism.

Science modelling in pre-calculus: how to make mathematics problems contextually meaningful
Sokolowski, Andrzej; Yalvac, Bugrahan; Loving, Cathleen
2011-04-01
'Use of mathematical representations to model and interpret physical phenomena and solve problems is one of the major teaching objectives in high school math curriculum' (National Council of Teachers of Mathematics (NCTM), Principles and Standards for School Mathematics, NCTM, Reston, VA, 2000). Commonly used pre-calculus textbooks provide a wide range of application problems. However, these problems focus students' attention on evaluating or solving pre-arranged formulas for given values. The role of scientific content is reduced to provide a background for these problems instead of being sources of data gathering for inducing mathematical tools. Students are neither required to construct mathematical models based on the contexts nor are they asked to validate or discuss the limitations of applied formulas. Using these contexts, the instructor may think that he/she is teaching problem solving, where in reality he/she is teaching algorithms of the mathematical operations (G. Kulm (ed.), New directions for mathematics assessment, in Assessing Higher Order Thinking in Mathematics, Erlbaum, Hillsdale, NJ, 1994, pp. 221-240). Without a thorough representation of the physical phenomena and the mathematical modelling processes undertaken, problem solving unintentionally appears as simple algorithmic operations. In this article, we deconstruct the representations of mathematics problems from selected pre-calculus textbooks and explicate their limitations. We argue that the structure and content of those problems limits students' coherent understanding of mathematical modelling, and this could result in weak student problem-solving skills. Simultaneously, we explore the ways to enhance representations of those mathematical problems, which we have characterized as lacking a meaningful physical context and limiting coherent student understanding. In light of our discussion, we recommend an alternative to strengthen the process of teaching mathematical modelling - utilization

The PIXE technique has been successfully applied to study crime related problems in forensic science. The experimental arrangements and various practical problems involved are discussed. Consistency and reproducibility checks are presented. The results from the gun-shot residue profiles of the associated elements about the bullet hole obtained for various firing distances showed that the sensitivity of the PIXE technique could play a vital role in forensic science in assigning the distance from the gun to the victim and identifying the type of bullet used. PIXE runs on other forensic related specimens demonstrate its usefulness in indetification and evaluation of vital parameters related to a crime. The reliability and the importance of the PIXE method in solving criminal and related problems in forensic science are discussed. (orig.)

Henry Head and the Theatre of Reverie
Directory of Open Access Journals (Sweden)
Tiffany Watt-Smith
2011-04-01
Full Text Available In 1903, the neurologist Henry Head (1861-1940 embarked on a painful self-experiment, in which he severed the radial nerve of his left arm, and then charted the gradual and faltering return of sensitivity to the limb over the next four and a half years. To directly experience his own sensations, Head entered into a trance-like state of distraction or reverie he called a ‘negative attitude of attention’. This article explores Head’s peculiar technique for looking within, and argues that while introspection was an established strategy in psychological laboratories, Head’s reverie also resonated with techniques associated with actors and theatrical audiences during this period. Viewing psychological self-experimentation through the lens of theatre, this article makes visible aspects of Head’s embodied, affective laboratory encounters, often obscured in accounts of his experiment. At the same time, it proposes that the broader historical and cultural significance of Head’s experiment lies in his attempt to observe himself by producing states of inattention and reverie at will, mental ‘attitudes’ that were themselves the subject of a rapidly evolving debate in scientific and aesthetic circles at the turn of the twentieth century.

Space life science and life support engineering are prominent problems in manned deep space exploration mission. Some typical problems are discussed in this paper, including long-term life support problem, physiological effect and defense of varying extraterrestrial environment. The causes of these problems are developed for these problems. To solve these problems, research on space life science and space medical-engineering should be conducted. In the aspect of space life science, the study of space gravity biology should focus on character of physiological effect in long term zero gravity, co-regulation of physiological systems, impact on stem cells in space, etc. The study of space radiation biology should focus on target effect and non-target effect of radiation, carcinogenicity of radiation, spread of radiation damage in life system, etc. The study of basic biology of space life support system should focus on theoretical basis and simulating mode of constructing the life support system, filtration and combination of species, regulation and optimization method of life support system, etc. In the aspect of space medical-engineering, the study of bio-regenerative life support technology should focus on plants cultivation technology, animal-protein production technology, waste treatment technology, etc. The study of varying gravity defense technology should focus on biological and medical measures to defend varying gravity effect, generation and evaluation of artificial gravity, etc. The study of extraterrestrial environment defense technology should focus on risk evaluation of radiation, monitoring and defending of radiation, compound prevention and removal technology of dust, etc. At last, a case of manned lunar base is analyzed, in which the effective schemes of life support system, defense of varying gravity, defense of extraterrestrial environment are advanced respectively.

To support our Lean culture of continuous improvement, we implemented a daily management system designed so critical metrics of operational success were the focus of local teams to drive improvements. We innovated a standardized visual daily management board composed of metric categories of Quality, Time, Inventory, Productivity, and Safety (QTIPS); frequency trending; root cause analysis; corrective/preventive actions; and resulting process improvements. In 1 year (June 2013 to July 2014), eight laboratory sections at Henry Ford Hospital employed 64 unique daily metrics. Most assessed long-term (>6 months), monitored process stability, while short-term metrics (1-6 months) were retired after successful targeted problem resolution. Daily monitoring resulted in 42 process improvements. Daily management is the key business accountability subsystem that enabled our culture of continuous improvement to function more efficiently at the managerial level in a visible manner by reviewing and acting based on data and root cause analysis.

Mobilizing science and technology to address the problems of the world's poor
International Nuclear Information System (INIS)
Sachs, J.
2001-01-01
Full text: Writing in The Economist of 15 February this year, Prof. Sachs raised several points that are relevant to any discussion of technical co-operation for sustainable development. He urges a stronger emphasis on the transfer of appropriate technology, and supports expanded roles for United Nations organizations in helping to solve the problems of the world's poorest countries. Here are some excerpts: 'A(n)...important challenge, as yet mainly unrecognised, is that of mobilising global science and technology to address the crises of public health, agricultural productivity, environmental degradation and demographic stress confronting these countries (i.e., the 42 so-called Highly Indebted Poor Countries - HIPCs, ed.) In part this will require that the wealthy governments enable the grossly underfinanced and underempowered United Nations institutions to become vibrant and active partners of human development.' The conditions in many HIPCs are worsening dramatically, even as global science and technology create new surges of wealth and well-being in richer countries. The problem is that, for myriad reasons, the technological gains in wealthy countries do not readily diffuse to the poorest ones....Research and development of new technologies are overwhelmingly directed at rich-country problems. To the extent that the poor face distinctive challenges, science and technology must be directed purposefully towards them (emphasis added). In today's global set-up, that rarely happens....Currently, the international system fails to meet the technological needs of the world's poorest.' Prof. Sachs has been one of the few development economists to consistently remind us that most of the world's poor live under vastly different environmental conditions - mainly tropical climates with their often unique disease agents and agricultural factors - than most of the rich. He points out that sustainable development is not possible unless the underlying ecological constraints are

Style and non-style in anatomical illustration: From Renaissance Humanism to Henry Gray.
Kemp, Martin
2010-02-01
Style is a familiar category for the analysis of art. It is less so in the history of anatomical illustration. The great Renaissance and Baroque picture books of anatomy illustrated with stylish woodcuts and engravings, such as those by Charles Estienne, Andreas Vesalius and Govard Bidloo, showed figures in dramatic action in keeping with philosophical and theological ideas about human nature. Parallels can be found in paintings of the period, such as those by Titian, Michelangelo and Hans Baldung Grien. The anatomists also claimed to portray the body in an objective manner, and showed themselves as heroes of the discovery of human knowledge. Rembrandt's painting of Dr Nicholas Tulp is the best-known image of the anatomist as hero. The British empirical tradition in the 18th century saw William Cheselden and William Hunter working with techniques of representation that were intended to guarantee detailed realism. The ambition to portray forms life-size led to massive volumes, such as those by Antonio Mascagni. John Bell, the Scottish anatomist, criticized the size and pretensions of the earlier books and argued for a plain style adapted to the needs of teaching and surgery. Henry Gray's famous Anatomy of 1858, illustrated by Henry Vandyke Carter, aspired to a simple descriptive mode of functional representation that avoided stylishness, resulting in a style of its own. Successive editions of Gray progressively saw the replacement of Gray's method and of all his illustrations. The 150th anniversary edition, edited by Susan Standring, radically re-thinks the role of Gray's book within the teaching of medicine.

An urgent problem in space materials science is simulating the interaction of vacuum ultraviolet (VUV) of solar emission with solids in space conditions, that is, producing a light source with a distribution that approximates the distribution of solar energy. Information is presented on the distribution of the energy flux of VUV of solar radiation. Requirements that must be satisfied by the VUV source used for space materials science are formulated, and a critical evaluation is given of the possibilities of using existing sources for space materials science. From this evaluation it was established that none of the sources of VUV satisfies the specific requirements imposed on the simulator of solar radiation. A solution to the problem was found to be in the development of a new type of source based on exciting a supersonic gas jet flowing into vacuum with a sense electron beam. A description of this gas-jet source, along with its spectral and operation characteristics, is presented.

Henri Becquerel: serendipitous brilliance
Margaritondo, Giorgio
2008-06-01
Serendipity has always been an attendant to great science. Arno Penzias and Robert Wilson discovered the cosmic background radiation after first mistaking it for the effect of pigeon droppings on their microwave antenna. US spy satellites detected gamma-ray bursts when surveying the sky for evidence of secret Soviet nuclear tests during the Cold War. Satyendra Bose arrived at Bose-Einstein statistics only after discovering that a mathematical error explained the experimental data concerning the photoelectric effect. In the words of science-fiction writer Isaac Asimov, "The most exciting phrase in science is not 'Eureka!', but rather, 'That's funny...'.

Social balance as a satisfiability problem of computer science.
Radicchi, Filippo; Vilone, Daniele; Yoon, Sooeyon; Meyer-Ortmanns, Hildegard
2007-02-01
Reduction of frustration was the driving force in an approach to social balance as it was recently considered by Antal [T. Antal, P. L. Krapivsky, and S. Redner, Phys. Rev. E 72, 036121 (2005)]. We generalize their triad dynamics to k-cycle dynamics for arbitrary integer k. We derive the phase structure, determine the stationary solutions, and calculate the time it takes to reach a frozen state. The main difference in the phase structure as a function of k is related to k being even or odd. As a second generalization we dilute the all-to-all coupling as considered by Antal to a random network with connection probability wcomputer science. The phase of social balance in our original interpretation then becomes the phase of satisfaction of all logical clauses in the satisfiability problem. In common to the cases we study, the ideal solution without any frustration always exists, but the question actually is as to whether this solution can be found by means of a local stochastic algorithm within a finite time. The answer depends on the choice of parameters. After establishing the mapping between the two classes of models, we generalize the social-balance problem to a diluted network topology for which the satisfiability problem is usually studied. On the other hand, in connection with the satisfiability problem we generalize the random local algorithm to a p-random local algorithm, including a parameter p that corresponds to the propensity parameter in the social balance problem. The qualitative effect of the inclusion of this parameter is a bias towards the optimal solution and a reduction of the needed simulation time.

The Henry coefficients of a single component adsorbent + adsorbate system are calculated from experimentally measured adsorption isotherm data, from which the heat of adsorption at zero coverage is evaluated. The first part of the papers relates to the development of thermodynamic property surfaces for a single-component adsorbent + adsorbate system1 (Chakraborty, A.; Saha, B. B.; Ng, K. C.; Koyama, S.; Srinivasan, K. Langmuir 2009, 25, 2204). A thermodynamic framework is presented to capture the relationship between the specific surface area (Ai) and the energy factor, and the surface structural and the surface energy heterogeneity distribution factors are analyzed. Using the outlined approach, the maximum possible amount of adsorbate uptake has been evaluated and compared with experimental data. It is found that the adsorbents with higher specific surface areas tend to possess lower heat of adsorption (ΔH°) at the Henry regime. In this paper, we have established the definitive relation between Ai and ΔH° for (i) carbonaceous materials, metal organic frameworks (MOFs), carbon nanotubes, zeolites + hydrogen, and (ii) activated carbons + methane systems. The proposed theoretical framework of At and AH0 provides valuable guides for researchers in developing advanced porous adsorbents for methane and hydrogen uptake. © 2009 American Chemical Society.

Network science, nonlinear science and infrastructure systems
2007-01-01
Network Science, Nonlinear Science and Infrastructure Systems has been written by leading scholars in these areas. Its express purpose is to develop common theoretical underpinnings to better solve modern infrastructural problems. It is felt by many who work in these fields that many modern communication problems, ranging from transportation networks to telecommunications, Internet, supply chains, etc., are fundamentally infrastructure problems. Moreover, these infrastructure problems would benefit greatly from a confluence of theoretical and methodological work done with the areas of Network Science, Dynamical Systems and Nonlinear Science. This book is dedicated to the formulation of infrastructural tools that will better solve these types of infrastructural problems. .

Coastal groundwater flow investigations at the Biscayne Bay, south of Miami, Florida, gave rise to the concept of density-driven flow of seawater into coastal aquifers creating a saltwater wedge. Within that wedge, convection-driven return flow of seawater and a dispersion zone were assumed by Cooper et al. (1964) to be the cause of the Biscayne aquifer `sea water wedge'. This conclusion was based on the chloride distribution within the aquifer and on an analytical model concept assuming convection flow within a confined aquifer without taking non-chemical field data into consideration. This concept was later labelled the `Henry Problem', which any numerical variable density flow program must be able to simulate to be considered acceptable. Both, `density-driven flow' and Tothian `groundwater flow systems' (with or without variable density conditions) are driven by gravitation. The difference between the two are the boundary conditions. 'Density-driven flow' occurs under hydrostatic boundary conditions while Tothian `groundwater flow systems' occur under hydrodynamic boundary conditions. Revisiting the Cooper et al. (1964) publication with its record of piezometric field data (heads) showed that the so-called sea water wedge has been caused by discharging deep saline groundwater driven by gravitational flow and not by denser sea water. Density driven flow of seawater into the aquifer was not found reflected in the head measurements for low and high tide conditions which had been taken contemporaneously with the chloride measurements. These head measurements had not been included in the flow interpretation. The very same head measurements indicated a clear dividing line between shallow local fresh groundwater flow and saline deep groundwater flow without the existence of a dispersion zone or a convection cell. The Biscayne situation emphasizes the need for any chemical interpretation of flow pattern to be supported by head data as energy indicators of flow fields

It is the digital library in all its aspects, it is the repository library for cultural heritage and “passive” collections and it offers a working place in its wonderful book tower of Henry van de Velde. The story of the book tower starts in the 1930s when Henry van de Velde was asked to build a University Library and offices for the department of Art history. His tower-idea was not exactly what the chief librarian had in mind, so he had to (network hard to get the building he wanted. It was finished on the verge of the second world war. The concrete building has a height of 64 meter, has 24 floors and a “belvedere” and houses almost 3 million books in closed racks.

From the late 1940s to the late 1980s, the Department of Energy (DOE) had a critical role in the Cold War. Many sites were built to contribute to the nation's nuclear weapons effort. However, not enough attention was paid to how the waste generated at these facilities should be handled. As a result, a number of sites fouled the soil around them or dumped low-level radioactive waste into nearby rivers. A DOE laboratory is under construction with a charter to help. Called the Environmental Molecular Sciences Laboratory (EMSL), this national user facility will be located at DOE's Pacific Northwest Laboratory (PNL) in Richland, WA. This laboratory has been funded by DOE and Congress to play a major role as the nation confronts the enormous challenge of reducing environmental and human risks from hundreds of government and industrial waste sites in an economically viable manner. The original proposal for the EMSL took a number of twists and turns on its way to its present form, but one thing remained constant: the belief that safe, permanent, cost-effective solutions to many of the country's environmental problems could be achieved only by multidisciplinary teams working to understand and control molecular processes. The processes of most concern are those that govern the transport and transformation of contaminants, the treatment and storage of high-level mixed wastes, and the risks those contaminants ultimately pose to workers and the public

In this speech, the President of France Jacques Chirac outlines the personality of the great scientists Henri Becquerel, Pierre and Marie Curie, and highlights their hard work and struggle to make science progress. Science always appears as a construction wonderfully logical but behind this facade, the daily life of research workers is made up of doubt, multiple choices, dead ends, errors and misinterpretations. The President wishes the nation to reach a perfect partnership with its scientific community. Science should be a source of inspiration for the industrial world but also a valuable help to solve present and future problems. Because of the universality of most problems, science has always favoured the cooperation between states. This cooperation should be turned into solidarity because whoever we are we live in the same world. (A.C.)

The Paradox of Being a Wounded Healer: Henri J.M. Nouwen’s Contribution to Pastoral Theology
Directory of Open Access Journals (Sweden)
S. Philip Nolte
2010-11-01
Full Text Available This article is the first in a series of two dealing with Henri Nouwen’s contribution to pastoral care. The present article focuses on the impact of cognitive dissonance and the role it plays in pastors becoming constrained in their ministry. The point of departure is that during the past two decades, pastors have been subjected to profound changes. While pastors view their involvement with people in the social and faith communities in which they live and work as guiding people towards a life of wholeness and integrity, they themselves, because of their own inner woundedness, struggle to live a life of wholeness. This article investigates how pastors can act congruently and with integrity in a world that has been profoundly changed by a shift from a modern to a postmodern paradigm. This reflection explores the ancient Greek mythological origins of the concept ‘wounded healer’. It also shows that, in its utilisation by the Swiss psychiatrist Carl Jung, the concept became a metaphor. This insight leads to a discussion of how Henri Nouwen applied the significance of the metaphor to pastoral ministry. The discussion takes on the form of certain relevant biographical side notes on Nouwen’s contribution to pastoral theology. The article concludes with an exposition of Nouwens’s use of the metaphor in his book, The wounded healer: Ministry in contemporary society.

The essence of the political (federal regulation is to ensure such equitable terms of exchange, in which regional differences would serve the purpose of integration and development of the national system. However, in order to ensure equitable interregional exchange, the objective heterogeneity of the Russia’s space should be identified and presented in the form of «inventory» of regional advantages and limitations. In terms of heterogeneity of the Russia’s space regional science needs to determine the spatial limits of applicability of different transformation ideologies, trim hyper centralized public policy (irrespective of used ideology, and, pointing to the structural constraints of grading transformations, formulate the terms of possible unity of the Russia’s space

The Effect of Problem-Solving Video Games on the Science Reasoning Skills of College Students
Fanetti, Tina M.
As the world continues to rapidly change, students are faced with the need to develop flexible skills, such as science reasoning that will help them thrive in the new knowledge economy. Prensky (2001), Gee (2003), and Van Eck (2007) have all suggested that the way to engage learners and teach them the necessary skills is through digital games, but empirical studies focusing on popular games are scant. One way digital games, especially video games, could potentially be useful if there were a flexible and inexpensive method a student could use at their convenience to improve selected science reasoning skills. Problem-solving video games, which require the use of reasoning and problem solving to answer a variety of cognitive challenges could be a promising method to improve selected science reasoning skills. Using think-aloud protocols and interviews, a qualitative study was carried out with a small sample of college students to examine what impact two popular video games, Professor Layton and the Curious Village and Professor Layton and the Diabolical Box, had on specific science reasoning skills. The subject classified as an expert in both gaming and reasoning tended to use more higher order thinking and reasoning skills than the novice reasoners. Based on the assessments, the science reasoning of college students did not improve during the course of game play. Similar to earlier studies, students tended to use trial and error as their primary method of solving the various puzzles in the game and additionally did not recognize when to use the appropriate reasoning skill to solve a puzzle, such as proportional reasoning.

Toward High-Performance Communications Interfaces for Science Problem Solving
Oviatt, Sharon L.; Cohen, Adrienne O.
2010-12-01
From a theoretical viewpoint, educational interfaces that facilitate communicative actions involving representations central to a domain can maximize students' effort associated with constructing new schemas. In addition, interfaces that minimize working memory demands due to the interface per se, for example by mimicking existing non-digital work practice, can preserve students' attentional focus on their learning task. In this research, we asked the question: What type of interface input capabilities provide best support for science problem solving in both low- and high- performing students? High school students' ability to solve a diverse range of biology problems was compared over longitudinal sessions while they used: (1) hardcopy paper and pencil (2) a digital paper and pen interface (3) pen tablet interface, and (4) graphical tablet interface. Post-test evaluations revealed that time to solve problems, meta-cognitive control, solution correctness, and memory all were significantly enhanced when using the digital pen and paper interface, compared with tablet interfaces. The tangible pen and paper interface also was the only alternative that significantly facilitated skill acquisition in low-performing students. Paradoxically, all students nonetheless believed that the tablet interfaces provided best support for their performance, revealing a lack of self-awareness about how to use computational tools to best advantage. Implications are discussed for how pen interfaces can be optimized for future educational purposes, and for establishing technology fluency curricula to improve students' awareness of the impact of digital tools on their performance.

The foundations of chaos revisited from Poincaré to recent advancements
2016-01-01
With contributions from a number of pioneering researchers in the field, this collection is aimed not only at researchers and scientists in nonlinear dynamics but also at a broader audience interested in understanding and exploring how modern chaos theory has developed since the days of Poincaré. This book was motivated by and is an outcome of the CHAOS 2015 meeting held at the Henri Poincaré Institute in Paris, which provided a perfect opportunity to gain inspiration and discuss new perspectives on the history, development and modern aspects of chaos theory. Henri Poincaré is remembered as a great mind in mathematics, physics and astronomy. His works, well beyond their rigorous mathematical and analytical style, are known for their deep insights into science and research in general, and the philosophy of science in particular. The Poincaré conjecture (only proved in 2006) along with his work on the three-body problem are considered to be the foundation of modern chaos theory.

Henry Thornton (1760-1815), whose major work - An Enquiry into the Nature and Effects of the Paper Credit of Great Britain - is celebrating its bicentennary in 2002, is considered today to be one of the most prominent classical monetary economist, in particular with regard to its seminal contribution to the theory of the lender of last resort. However, Thornton's original views about the rate of interest on bank credit have barely been commented so far. In this paper, we endeavour to link the...

Finite element methods for engineering sciences. Theoretical approach and problem solving techniques
Energy Technology Data Exchange (ETDEWEB)
Chaskalovic, J. [Ariel University Center of Samaria (Israel); Pierre and Marie Curie (Paris VI) Univ., 75 (France). Inst. Jean le Rond d' Alembert
2008-07-01
This self-tutorial offers a concise yet thorough grounding in the mathematics necessary for successfully applying FEMs to practical problems in science and engineering. The unique approach first summarizes and outlines the finite-element mathematics in general and then, in the second and major part, formulates problem examples that clearly demonstrate the techniques of functional analysis via numerous and diverse exercises. The solutions of the problems are given directly afterwards. Using this approach, the author motivates and encourages the reader to actively acquire the knowledge of finite- element methods instead of passively absorbing the material, as in most standard textbooks. The enlarged English-language edition, based on the original French, also contains a chapter on the approximation steps derived from the description of nature with differential equations and then applied to the specific model to be used. Furthermore, an introduction to tensor calculus using distribution theory offers further insight for readers with different mathematical backgrounds. (orig.)

Although science, technology, society and environment (STSE) education has gained considerable force in the past few years, it has made fewer strides in practice. We suggest that science teacher identity plays a role in the adoption of STSE perspectives. Simply put, issues-based STSE education challenges traditional images of a science teacher and science instructional ideologies. In this paper, we briefly describe the development of a multimedia documentary depicting issues-based STSE education in a teacher’s class and its subsequent implementation with 64 secondary student-teachers at a large Canadian university. Specifically, we set out to explore: (1) science teacher candidates’ responses to a case of issues-based STSE teaching, and (2) how science teacher identity intersects with the adoption of STSE perspectives. Findings reveal that although teacher candidates expressed confidence and motivation regarding teaching STSE, they also indicated decreased likelihood to teach these perspectives in their early years of teaching. Particular tensions or problems of practice consistently emerged that helped explain this paradox including issues related to: control and autonomy; support and belonging; expertise and negotiating curriculum; politicization and action; and biases and ideological bents. We conclude our paper with a discussion regarding the lessons learned about STSE education, teacher identity and the role of multimedia case methods.

Anarchism and homosexuality in Wilhelmine Germany: Senna Hoy, Erich Mühsam, John Henry Mackay.
Fähnders, W
1995-01-01
Homosexuality and its social and legal suppression were heatedly discussed in early twentieth-century Germany, including on the left. Among the anarchists, positions with markedly diverse forms of argument were espoused by such prominent advocates of individualist anarchism as John Henry Mackay and by others coming from the Bakuninist tradition, such as Senna Hoy and Erich Mühsam. Their writings evidence that prior to World War I and into the 1920s, German anarchists--especially when compared with the Social Democrats--intervened consistently on behalf of individual self-determination extending into the sexual sphere, even though an undercurrent of hostility toward homosexuals persisted within the leftist movement as a whole.

Zuk, W.M.
1997-01-01
The Australian Nuclear Science and Technology Organisation (ANSTO) has for many years been involved in applying nuclear science-based and related technologies to the understanding of environmental processes and to the development and implementation of practical and effective solutions to site specific problems, for a broad spectrum of industry, government regulatory agencies, and other organisations in Australia, Europe, North and South America and South East Asia. ANSTO's environmental science program arose out of the need for research to predict, measure, evaluate and monitor the environmental impacts associated with : uranium mining and processing in Australia; the operation of the research reactor at Lucas Heights; and the safe treatment and disposal of radioactive and conventional wastes associated with these activities. The expertise developed in these activities, has found application to a much broader range of environmental concerns. This paper will present an overview of ANSTO's application of nuclear science-based techniques to, inter alia: coastal and marine studies; minesite rehabilitation; transport and geochemical modelling of radionuclides, heavy metals and organic chemicals in the geosphere; the application of naturally-occurring radionuclides and radioactive tracers to corrosion and sedimentation studies in the coastal environment; dating sediments, fish corals and archaeological samples; the understanding of the kinetics and the physiological responses of aquatic organisms to radionuclides and metals in the environment: and the use of aquatic organism as archival and 'realtime' monitors of pollutants

Full Text Available Teamwork has become an integral part of most organisations today, and it is clearly important in Science and other disciplines. In Science, research teams increase in size while the number of single-authored papers and patents decline. Team-work in laboratory sciences permits projects that are too big or complex for one individual to be tackled. This development requires that students gain experience of team-work before they start their professional career. Students working in teams this may increase productivity, confidence, innovative capacity and improvement of interpersonal skills. Problem-based learning (PBL is an instructional approach focusing on real analytical problems as a means of training an analytical scientist. PBL may have a positive impact on team-work skills that are important for undergraduates and postgraduates to enable effective collaborative work. This survey of the current literature explores the development of the team-work skills in Biomedical Science students using PBL.

Attitude, Skills, Knowledge (ASK) - In this order, these are fundamental characteristics of scientific innovators. Through first-hand practice in using science to unpack and solve complex real-world problems, students can become self-motivated scientific leaders. This presentation describes the pedagogy of a recently developed interdisciplinary undergraduate science education program at the University of Massachusetts Amherst focused on addressing global challenges with scientific solutions. Integrated Concentration in Science (iCons) is an overarching concentration program that supplements the curricula provided within each student's chosen major. iCons is a platform for students to perform student-led research in interdisciplinary collaborative teams. With a schedule of one course per year over four years, the cohort of students move through case studies, analysis of real-world problems, development of potential solutions, integrative communication, laboratory practice, and capstone research projects. In this presentation, a track emphasizing renewable energy science is used to illustrate the iCons pedagogical methods. This includes discussion of a third-year laboratory course in renewable energy that is educationally scaffolded: beginning with a boot camp in laboratory techniques and culminating with student-designed research projects. Among other objectives, this course emphasizes the practice of using reflection and redesign, as a means of generating better solutions and embedding learning for the long term. This work is supported in part by NSF grant DUE-1140805.

A Study on Teaching Gases to Prospective Primary Science Teachers Through Problem-Based Learning
Senocak, Erdal; Taskesenligil, Yavuz; Sozbilir, Mustafa
2007-07-01
The aim of this study was to compare the achievement of prospective primary science teachers in a problem-based curriculum with those in a conventional primary science teacher preparation program with regard to success in learning about gases and developing positive attitudes towards chemistry. The subjects of the study were 101 first year undergraduate students, who were in two different classes and who were taught by the same lecturer. One of the classes was randomly selected as the intervention group in which problem-based learning (PBL) was used, and the other as the control in which conventional teaching methods were used. The data were obtained through use of the gases diagnostic test (GDT), the chemistry attitude scale (CAS), and scales specific to students’ evaluation of PBL such as the peer evaluation scale (PES), self evaluation scale (SES), tutor’s performance evaluation scale (TPES) and students’ evaluation of PBL scale (SEPBLS). Data were analysed using SPSS 10.0 (Statistical Package for Social Sciences). In order to find out the effect of the intervention (PBL) on students’ learning of gases, independent sample t-tests and ANCOVA (analysis of co-variance) were used. The results obtained from the study showed that there was a statistically significant difference between the experimental and control groups in terms of students’ GDT total mean scores and, their attitude towards chemistry, as well as PBL has a significant effect on the development of students’ skills such as self-directed learning, cooperative learning and critical thinking.

Is problem-based learning a quality approach to education in health sciences?
Kwan, C Y
2001-07-01
The Faculty of Health Sciences at McMaster University has pioneered, experimented and finally excelled in the application of problem-based learning (PBL) as an entire medical curriculum for the past 35 years. However, the general practice of PBL by other medical schools around the globe has progressed slowly. In theory, PBL as an educational philosophy has long been considered as a quality cognitive concept and was adopted by many medical schools via curriculum reform to improve students' learning attitude. In practice, what is the experimental evidence for PBL meeting the expectation of a quality education in health sciences? How do we differentiate problems associated with PBL philosophy per se from those associated with the ways PBL are handled and implemented? I will address these questions from the perspective of the assessment of performance of students, graduates and practising physicians from the PBL track compared to those from the conventional track based on literature information. Ample evidence suggests that PBL is superior in producing more compassionate physicians and graduates with lifelong learning and leadership quality. But, some educators and administrators are still skeptical that the benefits from PBL may be too marginal to justify the resources required in sustaining it. In this presentation, the assessment of PBL, in both theoretical and practical terms, will be discussed using McMaster PBL as a convenient example because of its relatively long history in practising PBL in medical education.

Une autre ville pour une autre vie. Henri Lefebvre et les situationnistes

Full Text Available L’un des traits distinctifs du mouvement situationniste est de s’être constamment préoccupé de la question urbaine. Conçue comme l’espace de production de la société du spectacle mais aussi comme un terrain de lutte et d’expérimentation, la ville a représenté pour ce mouvement estudiantin, proche d’Henri Lefebvre, le lieu d’une réinvention radicale de la vie quotidienne. Cet article revient sur la critique situationniste de l’urbanisme de l’après-guerre ainsi que sur les pratiques auxquelles elle a donné lieu (détournement, dérive, cartes psychogéographiques, construction de situations éphémères. Celles-ci peuvent être regardées comme la première expression d’un « droit à la ville », tel que l’entendait Lefebvre. Reste à savoir si le groupe de Guy Debord souhaitait véritablement « changer la ville pour changer la vie » ou si la ville n’était que le théâtre d’une révolution à venir.One of the distinctive traits of the situationist movement is its constant preoccupation with the urban issue. For this student movement close to Henri Lefebvre, the city has been thought of as a choice generic location for the production of the Society of the Spectacle, but also as a test ground for struggle and experimentation – the place where a radical reinvention of daily life can occur. This paper goes back to the situationist critique of post-war urbanism, as well as the behaviors and practices it has given birth to (misappropriation, drifts in meaning, psychogeographic maps, the construct of short-lived situations. These can be seen as the first expression of a « right to the city », in the sense Lefebvre originally meant it have. However, it is still unknown whether Guy Debord's group really wished to « change city-life to change life itself », or if to them the city was merely a theater for the enactment of a revolution to come.

A new booklet 'Science Serving People' features stories about how IAEA-supported projects are making a difference in many poorer countries. The stories describe applications of nuclear science and technology that are being used through technical cooperation channels to overcome challenges of water scarcity, food shortage, malnutrition, malaria, environmental degradation and many other problems. They also illustrate how the complementary development, safety, and security initiatives of the IAEA are fostering atoms for peace in the developing world. Extreme poverty and deprivation remain a problem of monumental proportions at the dawn of the 21st century, notes IAEA Director General Mohamed ElBaradei in the booklet's Introduction. Through effective partnerships, collaborative research, and strategic direction, the IAEA is contributing to global efforts to help the poor. IAEA programmes have entered an important phase, he said, in which scientific contributions to Member States are yielding very sizeable human benefits. It's clear that science and technology must be better mobilized to meet the needs of the poor, emphasizes Jeffrey Sachs, Director of the Earth Institute at Columbia University, USA, and Special Advisor to UN Secretary-General Kofi Annan. The UN agencies, such as the IAEA, have a great role to play, he says in the booklet's Foreword. This is especially so, he points out, if they act as a bridge between the activities of advanced- country and developing country scientific centres, and if they help to harness the advances of world science for the poor as well as the rich. The bottom line, he concludes, is that rich countries should expand support for those United Nations organizations that can help in solving the unique problems confronting the world's poorest peoples. The booklet features stories on managing water resources, promoting food security, focusing science on health problems, new tools for environmental management, and strengthening nuclear

Support of a Problem-Based Learning Curriculum by Basic Science Faculty

William L. Anderson
2002-11-01
Full Text Available Although published reports describe benefits to students of learning in a problem-based, student-centered environment, questions have persisted about the excessive faculty time commitments associated with the implementation of PBL pedagogy. The argument has been put forward that the excessive faculty costs of such a curriculum cannot be justified based upon the potential benefits to students. However, the magnitude of the faculty time commitment to a PBL curriculum to support the aforementioned argument is not clear to us and we suspect that it is also equally unclear to individuals charged with making resource decisions supporting the educational efforts of the institution. Therefore, to evaluate this cost - benefit question, we analyzed the actual basic science faculty time commitment in a hybrid PBL curriculum during the first phase 18 months of undergraduate medical education. The results of this analysis do demonstrate an increase in faculty time commitments but do not support the argument that PBL pedagogy is excessively costly in terms of faculty time. For the year analyzed in this report, basic science faculty members contributed on average of 27.4 hours to the instruction of medical students. The results of the analysis did show significant contributions (57% of instructional time by the clinical faculty during the initial 18 months of medical school. In addition, the data revealed a four-fold difference between time commitments of the four basic science departments. We conclude that a PBL curriculum does not place unreasonable demands on the time of basic science faculty. The demands on clinical faculty, in the context of their other commitments, could not be evaluated. Moreover, this type of analysis provides a tool that can be used to make faculty resource allocation decisions fairly.

The enigmatic figure of Dr Henry Maudsley (1835-1918).
Pantelidou, Maria; Demetriades, Andreas K
2014-08-01
In spite of his contribution to psychiatry in 19th century Britain, Henry Maudsley remains a mysterious figure, a man mostly known for his donation to the London County Council for the building of the Maudsley Hospital and for The Maudsley Annual Lecture created in honour of his benevolence. Besides Sir Aubrey Lewis' article in 1951 and Michael Collie's attempt in 1988 to construct a biographical study on Maudsley, there does not seem to be any current endeavour to tell the story of his life, whereas Trevor Turner's contribution to the 2004 Oxford Dictionary of National Biography gives a somewhat scathing but unattributed account of Maudsley's personality. This essay attempts to explore his contributions to the Medico-Psychological Association (MPA), the current Royal College of Psychiatrists, his editorship of the Journal of Mental Health (currently named the British Journal of Psychiatry), his literary contributions and his vision for a psychiatric hospital. This essay is an attempt to demystify his figure and to explore some of the rumours and criticisms surrounding his name and the reasons why so little has been written about him. It is also a venture to unravel his complex personality and his intricate philosophy. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

Obituary: Roy Henry Garstang (1925-2009)
Malville, J.

. He constructed and modified a light pollution model (Dust and Light Pollution, PASP 103:1109 (1991)) which included an ozone layer, scattering of light by molecules and aerosols with improved variations with altitude, curvature of the earth, and a dust layer of dust either volcanic or desert origin. His models have become the standard for the field and have successfully reproduced the variation of sky glow with position in the sky and with distance from light sources. His models raised awareness of the factors contributing to light pollution at observatory sites and led to efforts to reduce urban light pollution. Garstang played an important role in the teaching program of the CU Bolder Astrophysics and Planetary Science department, teaching large introductory classes, laboratory and observatory sessions as well as upper division classes and graduate classes. His appetite for teaching undergraduate can be appreciated by some of the laboratory exercise he invented such as measuring the solar constant by the rate of rise of temperature inside closed car ("How hot does your parked car become?" AAPT Announce 18:139 (1988)). In 1994 he published a letter in AmJPh about a continuing discussion of SI units. The letter reveals much about his approach to life and physics. "I have done a lot of work during the last 15 years on light pollution. If you want to reach lighting engineers you have to talk about lumens, lux, foot-candles, and whatever. If you do not, your reward is simply not to be understood. Photons per square meter per second per steradian means nothing to them. The problem is doubly compounded because astronomers have their own traditional units, such as number of tenth magnitude stars per square degree, magnitudes per square arc second, and so on, which are equally obscure to the engineering community. By all means work in metric, but be prepared to quote your main results in language understood by the consumers of your results. In fact, a little common sense is

Science, state, and spirituality: Stories of four creationists in South Korea.
Park, Hyung Wook; Cho, Kyuhoon
2018-03-01
This paper presents an analysis of the birth and growth of scientific creationism in South Korea by focusing on the lives of four major contributors. After creationism arrived in Korea in 1980 through the global campaign of leading American creationists, including Henry Morris and Duane Gish, it steadily grew in the country, reflecting its historical and social conditions, and especially its developmental state with its structured mode of managing science and appropriating religion. We argue that while South Korea's creationism started with the state-centered conservative Christianity under the government that also vigilantly managed scientists, it subsequently constituted some technical experts' efforts to move away from the state and its religion and science through their negotiation of a new identity as Christian intellectuals ( chisigin). Our historical study will thus explain why South Korea became what Ronald Numbers has called "the creationist capital of the world."

Henry Solomon Wellcome: A philanthropist and a pioneer sponsor of medical research in the Sudan.
Adeel, Ahmed Awad A
2013-01-01
Henry Solomon Wellcome, the famous drug manufacturer had a fascinating association with the Sudan. Besides supporting tropical medicine research in this country, he established an extensive project in the Sudan that aimed at combining archeological excavations, philanthropy and social reform. This article is an archives-based account on this side of Wellcome's association with the Sudan. The article starts with Wellcome's early years in the American Midwest and the evolution of his career and his rise as a world-renowned drug manufacturer. After the battle of Omdurman, Wellcome visited Sudan in 1900 - 1901 where he offered to support the establishment of the research laboratories which later came to be known as the Wellcome Tropical Research Laboratories in Khartoum. He then became directly involved in the planning and running of extensive archeological excavations in the central Sudan. This project served as a field in which Wellcome found an outlet for his philanthropy. More than 4000 labourers were employed in Jebel Moya. Professional archeologists and anatomists were recruited by Wellcome to supervise the work, and all the requirements in terms of equipment were catered for. Wellcome devised a Savings Bank System whereby part of the earnings of each labourer were saved to him till the end of the season. He also introduced one of his innovations: aerial photography using box kite which was used for the first time in archeology. Wellcome made it a rule that no applicant should be turned away. The Camp Commandant had to find suitable work for each applicant, including the handicapped who were assigned to appropriate jobs like mending baskets or cutting grass for building huts. Wellcome's welfare work had a significant impact on the local inhabitants of Jebel Moya. Henry Solomon Wellcome, 1906. Oil painting by Hugh Goldwin Riviere. Credit: Wellcome Library.

Research briefing on contemporary problems in plasma science
International Nuclear Information System (INIS)
1991-01-01
An overview is presented of the broad perspective of all plasma science. Detailed discussions are given of scientific opportunities in various subdisciplines of plasma science. The first subdiscipline to be discussed is the area where the contemporary applications of plasma science are the most widespread, low temperature plasma science. Opportunities for new research and technology development that have emerged as byproducts of research in magnetic and inertial fusion are then highlighted. Then follows a discussion of new opportunities in ultrafast plasma science opened up by recent developments in laser and particle beam technology. Next, research that uses smaller scale facilities is discussed, first discussing non-neutral plasmas, and then the area of basic plasma experiments. Discussions of analytic theory and computational plasma physics and of space and astrophysical plasma physics are then presented

About Time. Physics, Philosophy and the Battle Between Albert Einstein and Henri Bergson
Frank, Adam
The historical relationship between physics and philosophy has had many famous high and low points. The two function best when both can challenge and support each other. In this talk I explore the famous debate between Albert Einstein and Henri Bergson over the nature of time. While history rightly judged Einstein to have won the debate in terms of relativity, there were deeper aspects of Bergsons critique that remain unappreciated. We will explore the different ways philosophy approaches the issue of time. In particular, we will look at the Continental Schools\\x9D, such as Phenomenology, which brings a unique perspective to the debate lying outside the traditional approach of physicists. From this perspective questions related to the act of being an observer, its essential subjective nature and the proper context of physics can be explored.

A portrait of Henry VIII on oak panel c. 1535 has recently undergone technical examination to inform questions regarding authorship and the painting's relationship to a group of similar works in the collections of the National Portrait Gallery, London, and the Society of Antiquaries. Due to previous conservation treatments of the painting, the conventional transmission X-radiograph image was difficult to interpret. As a result, the painting underwent high-definition X-ray fluorescence (XRF) elemental mapping on the X-ray fluorescence microscopy beamline of the Australian Synchrotron. Scans were conducted at 12.6 and 18.5 keV, below and above the lead (Pb) L edges, respectively. Typical scan parameters were 120 μm pixel size at 7 ms dwell time, with the largest scan covering an area 545 x 287 mm{sup 2} collected in 23 h (10.8 MP). XRF mapping of the panel has guided the conservation treatment of the painting and the revelation of previously obscured features. It has also provided insight into the process of making of the painting. The informative and detailed elemental maps, alongside ultra-high-definition scans of the painting undertaken before and after varnish and over-paint removal, have assisted in comparison of the finely painted details with the London paintings. The resolution offered by the combination of imaging techniques identifies pigment distribution at an extremely fine scale, enabling a new understanding of the artist's paint application. (orig.)

Fathoming the hydrosphere (Henry Darcy Medal Lecture)
van de Giesen, Nick
2015-04-01
As Lord Kelvin observed: "If you can not measure it, you can not improve it." Measurement is the start of all scientific knowledge. Measurement sets science apart from metaphysical speculation. Measurement is not the last word in science but it is the first. In hydrology, progress in measurement methods has not been as rapid as in sister Earth sciences such as meteorology, oceanography, or geodynamics. Of the hundreds of scientific satellites, only one has hydrology as its main mission at the time of this writing (hopefully two at the time of the lecture). The closest we come to a large measurement infrastructure is an experimental watershed. Nothing wrong with an experimental watershed but it does not compare to, say, the Square Kilometer Array with its exabyte per day output. We tend to give up quickly because we will always have to work with effective parameters that can not be measured directly. We will never be able to know all stomata in a tree and how they interact with the turbulent flow through the canopy. We will never be able to know all pores in a soil and how water moves through them. But also effective parameters have to be measured, be it indirectly. No surprise then that my presentation will focus on measurements in hydrology and water management. First, the fun aspects and intellectual challenges of developing new measurement methods will be highlighted. From weighing trees to listening to rain to taking a stream's temperature, we have had many interesting experiences over the years. Second, the balance between model complexity and data availability will be discussed. Although there is a generally recognized need for parsimonious models in hydrology, formal approaches to finding the correct level of complexity are rare. Some complexity control approaches, borrowed from computer science, will be presented together with a hydrological application. As it turns out, these methods seem to predict nicely the onset of equifinality or the statistical

A Note on Child Neglect in American Victorianism: Henry James’ "The Pupil"
Directory of Open Access Journals (Sweden)
F. Gül KOÇSOY
2016-12-01
Full Text Available In this study, the theme of “neglected child” in Henry James’ “The Pupil” (1891 is explored. Morgan is a neglected child with unscrupulous parents who hold strictly on the Victorian values which reflect American cultural consciousness in the last decades of 19th century. Although he is a brilliant boy, the family does not love him; because he reminds them of their vulgarity. They neglect him physically and emotionally, seeing him as a burden. Although his tutor tries to keep the boy from the family’s corruption, he contributes to his death; he neglects his illness and deserts him when he is most needy. As an interpreter, James draws attention to the situation of children that are not working but being tutored at home. He criticizes this culture’s general attitude towards children. It is a disturbing social reality and he shows how that materialistic culture victimizes children in terms of neglectful parenting

Primater emellan. En läsning av Henry Drummonds berättelse ”Apan som ingen kunde döda”

Full Text Available ”The anthropocentric primate. A species discursive reading of the story ‘The monkey that would not kill.’” In children's literature nonhuman primates are often represented either as ferocious beasts or as curios and charmful vicarious children. In this article I demonstrate how these different constructions interestingly coexist in the popular story ”The monkey that would not kill”, written by the Scottish evangelist and professor of the natural sciences Henry Drummond in 1891. My study anchors the figuration of the monstrous ape historically in a Christian discourse and the figuration of the childlike ape in a zoological discourse, and link them to the literary genres of horror and comedy, respectively. Both of the figurations are anthropocentric in their reductive ways of representing the ape as strange enemy or subordinate ”friend”: they confirm the hierarchic dualism between man and ape. My reading also points out the excessive passion that characterizes the meeting between the species in the story, as a kind of leakage from the dualism. In light of Giorgio Agamben's concept of the ”anthropological machine”, I conclude the article reflecting on the human shepherd's energetic attempts to kill the animal not only as an act of domination, but also as bearing witness to the obsession with ”experimenting” with other primates, in order to consolidate a human species identity.

Full Text Available The Turn of the Screw by Henry James has inspired the most various critical debates for over a century. What is hidden in the folds of the story? What kind of impact does it have on the reader? Like a borderless nebula who attracts and reflects light from other stars, this novella is permeated by a vide fascinant, by a chaotic and disturbing matter “such stuff as dreams are made”. This feeling of absence and uncertainty, that characterizes the story, developed trough the contribution of readers and critics and it found a further still precious echo in The Innocents, a film directed by Jack Clayton in 1961.

Solving complex problems in large-scale research programmes requires cooperation and division of labour. Simultaneously, large-scale problem solving also gives rise to unintended side effects. Based upon 5 years of researching two large-scale nutrigenomic research programmes, we argue that problems are fragmented in order to be solved. These sub-problems are given priority for practical reasons and in the process of solving them, various changes are introduced in each sub-problem. Combined with additional diversity as a result of interdisciplinarity, this makes reassembling the original and overall goal of the research programme less likely. In the case of nutrigenomics and health, this produces a diversification of health. As a result, the public health goal of contemporary nutrition science is not reached in the large-scale research programmes we studied. Large-scale research programmes are very successful in producing scientific publications and new knowledge; however, in reaching their political goals they often are less successful.

Full Text Available Henri Wallon, filósofo, médico e psicólogo francês, contribuiu para a psicologia não apenas com uma teoria da emoção ou ainda com suas discussões e divergências com Jean Piaget. Dentre suas contribuições pouco discutidas estão sua teoria sobre a inteligência, suas discussões sobre a origem e o desenvolvimento do pensamento discursivo nas crianças e, talvez menos conhecidas, suas reflexões e proposições sobre a transição entre uma inteligência sensório-motora (caracterizada pela capacidade de resolver problemas práticos, mas sem o auxílio da reflexão e uma outra, inteligência discursiva (caracterizada pela utilização e intermediação dos símbolos e representações. Sabe-se que sua proposição para essa transição, diversamente de Piaget, que ressalta a continuidade e a preparação do simbólico pelo esquematismo sensório-motor, é marcada justamente pela não continuidade entre uma inteligência e outra, pela intromissão de fatores externos tais como a cultura, o social e a linguagem, e pela complexa interação entre todos esses fatores. Para melhor compreender a proposta walloniana sobre a formação do símbolo é necessário, pois, que ingressemos na sua teoria como um todo, buscando decifrar seus conceitos de emoção, comportamento simbólico, inteligência, fatores de desenvolvimento e outros. Em uma sociedade como a nossa, baseada no comportamento simbólico, entender como se dá, qual a origem e o desenvolvimento do pensamento simbólico podem ser conhecimentos de grande valia.Henri Wallon, French philosopher, physician, and psychologist, has given psychology contribution not only with his emotion theory and with his arguments and disagreements with Jean Piaget.

The Works of Henry Moseley, 1887-1915
Scerri, Eric
2013-04-01
In 1913 Henry Moseley, an unknown young English physicist published an article in the Philosophical Magazine under the title of ``The High Frequency Spectra of the Elements.'' The 10-page article was to have far reaching implications in both chemistry and physics and helped to resolve a major conundrum in the periodic table of the elements. The talk will briefly examine the life and work of Moseley who died tragically while fighting in the trenches of World War I in 1915. The build-up to the discovery of atomic number took several different avenues including contributions from Rutherford and Barkla. However the more direct motivation for Moseley's work, as he readily acknowledged, were the articles of an unknown Dutch econometrician Anton Van den Broek who attempted to improve on Mendeleev's periodic table. Moseley began as a student of Rutherford at Manchester and took a keen interest in the development of research using X-rays following the work of Roentgen, von Laue and Bragg. Although Rutherford was at first reluctant to enter this new field he soon yielded to young Moseley's request and sent him to Leeds for brief training with Bragg. On returning to Manchester, Moseley devised an ingenious apparatus in which a set of metal samples could be rotated so as to become the target for a beam of electrons in order to measure the frequencies of the emitted K X-rays. The first set of such experiments used nine successive elements in the periodic table, from titanium to zinc. Moseley's now immense fame rests with the results of this study as well as a subsequent one which extended the study into a further 30 elements, in addition to the use that his method was put to by himself as well as subsequent chemists and physicists.

Slavkin, Michael
What impact do gender roles and self-esteem have on early adolescent girls' abilities to solve problems when participating in natural science-related activities? Bronfenbrenner's human ecology model and Barker's behavior setting theory were used to assess how environmental contexts relate to problem solving in scientific contexts. These models also provided improved methodology and increased understanding of these constructs when compared with prior research. Early adolescent girls gender roles and self-esteem were found to relate to differences in problem solving in science-related groups. Specifically, early adolescent girls' gender roles were associated with levels of verbal expression, expression of positive affect, dominance, and supportive behavior during science experiments. Also, levels of early adolescent girls self-esteem were related to verbal expression and dominance in peer groups. Girls with high self-esteem also were more verbally expressive and had higher levels of dominance during science experiments. The dominant model of a masculine-typed and feminine-typed dichotomy of problem solving based on previous literature was not effective in Identifying differences within girls' problem solving. Such differences in the results of these studies may be the result of this study's use of observational measures and analysis of the behavior settings in which group members participated. Group behavior and problem-solving approaches of early adolescent girls seemed most likely to be defined by environmental contexts, not governed solely by the personalities of participants. A discussion for the examination of environmental factors when assessing early adolescent girls' gender roles and self-esteem follows this discussion.

The Right to the City: From Henri Lefebvre to the Analysis about the Contemporary Capitalist City
Directory of Open Access Journals (Sweden)

Full Text Available The right to the city, defined by Henri Lefebvre in 1967 as the right of urban inhabitants to build, decide and create the city, and make of it a privileged space of anti-capitalist struggle, is again at the center of political debate. Social scientists, social movements, international aid agencies and States take it as a benchmark for policy analysis and to discuss the urban changes in contemporary capitalist cities. This article discusses the assumptions made by Lefebvre in 1967 and the transformation that the concept of right to the city has had from authors such as David Harvey, Edward Soja and Ana Fani Alessandri Carlos.

The "pavilion plan" for hospital design originated in France in the 18th century and was popularised in England by John Roberton and George Godwin in the mid-19th century; the underlying rationale was that with improved ventilation the mortality rate (at that time exceedingly high) was significantly reduced. Among the enthusiasts for this new style was Florence Nightingale (herself a miasmatist)--who had experienced astronomically high death rates in the hospital at Scutari during the Crimean War (1854-6). One of the leading exponents of this style of hospital architecture was Henry Currey (1820-1900) whose greatest achievement was undoubtedly the design for the new St Thomas's Hospital on the Lambeth Palace Road.

This study investigated the effects of a shared, Intranet science environment on the academic behaviors of problem-solving and metacognitive reflection. Seventy-eight subjects included 9th and 10th grade male and female biology students. A quasi-experimental design with pre- and post-test data collection and randomization occurring through assignment of biology classes to traditional or shared, Intranet learning groups was employed. Pilot, web-based distance education software (CourseInfo) created the Intranet learning environment. A modified ecology curriculum provided contextualization and content for traditional and shared learning environments. The effect of this environment on problem-solving, was measured using the standardized Watson-Glaser Critical Thinking Appraisal test. Metacognitive reflection, was measured in three ways: (a) number of concepts used, (b) number of concept links noted, and (c) number of concept nodes noted. Visual learning software, Inspiration, generated concept maps. Secondary research questions evaluated the pilot CourseInfo software for (a) tracked user movement, (b) discussion forum findings, and (c) difficulties experienced using CourseInfo software. Analysis of problem-solving group means reached no levels of significance resulting from the shared, Intranet environment. Paired t-Test of individual differences in problem-solving reached levels of significance. Analysis of metacognitive reflection by number of concepts reached levels of significance. Metacognitive reflection by number of concept links noted also reach significance. No significance was found for metacognitive reflection by number of concept nodes. No gender differences in problem-solving ability and metacognitive reflection emerged. Lack of gender differences in the shared, Intranet environment strongly suggests an equalizing effect due to the cooperative, collaborative nature of Intranet environments. Such environments appeal to, and rank high with, the female

Online citizen science games: Opportunities for the biological sciences.
Curtis, Vickie
2014-12-01
Recent developments in digital technologies and the rise of the Internet have created new opportunities for citizen science. One of these has been the development of online citizen science games where complex research problems have been re-imagined as online multiplayer computer games. Some of the most successful examples of these can be found within the biological sciences, for example, Foldit, Phylo and EteRNA. These games offer scientists the opportunity to crowdsource research problems, and to engage with those outside the research community. Games also enable those without a background in science to make a valid contribution to research, and may also offer opportunities for informal science learning.

A pioneer of Australian paediatrics: Dr Henry Edward Brown (1858-1931).
Isles, Alan F; Roper, Peter; Pearn, John H
2014-11-13
The emergence of paediatrics as a specialty in Australian medicine dates from the last two decades of the 19th century. Among the pioneers of pre-Federation paediatrics, we include Dr Henry Edward Brown (1858-1931), an Irish-born physician and surgeon who became the first paediatrician to practise in the northern half of the Australian continent. In 1885, he was appointed as the medical superintendent of the Rockhampton Children's Hospital, itself a pioneer institution in the care of sick and injured children. Dr H.E. Brown also served as medical officer of health concurrently in three Queensland shires. He was a leader in the literary and sporting life of the busy port town of Rockhampton and a scholar and significant philanthropist in the domain of French literature. His life was and remains an exemplar of a class of pre-Federation paediatricians who established the ethos of clinical and societal service, which remains as a core feature of the speciality discipline of paediatrics in the 21st century. © 2014 The Authors.

Reformation or Revolution? Herman Bavinck and Henri de Lubac on Nature and Grace

2017-10-01
Full Text Available Henri de Lubac’s treatment of the relationship between nature and grace will be critiqued by Herman Bavinck’s ‘grace restores nature’ theme. In two significant addresses, Bavinck critiqued a Roman Catholic approach to nature and grace. De Lubac’s influence upon Roman Catholic thinking addressing nature and grace occurred post-Bavinck and has altered Catholic thinking on the subject. Neo-Calvinist scholar, Wolter Huttinga admits that Bavinck and de Lubac offer similar critiques of Roman Catholicism (Huttinga 2014. The question remains then, do Bavinck’s critiques still hold? I propose that Bavinck’s account of grace restores nature still makes valid critiques of a post-Vatican II construction of nature and grace. The paper is broken into three sections: (1 an exploration of de Lubac’s nature and grace theme, (2 the framework of Bavinck’s ‘grace restores nature’ theme, and (3 a Bavinckian critique of de Lubac’s nature and grace theme.

Problems of military conversion and science in Russia
International Nuclear Information System (INIS)
Malyshev, N.
1994-01-01
The development of science in Russia was determined by the political guidelines of State. Although science in USSR was not always an ingenious productive force, till recent years it was a factor of national pride. It was taken as a matter of course not to calculate the expenses and losses during the implementation of state objectives, such as creation of powerful research and experimental base in the sphere of nuclear physics. development of inter-continental ballistic missiles, the opening of outer space. The fall of financing in 1990 induced the danger of destruction of many famous schools, research teams, important scientific institutions. The collapse of USSR brought heavy consequences which were connected to the rupture of not only economic but also scientific relations. Until now Russia has no regional scientific policy. For the fundamental change of the situation Russia needs to reach an activation of participation of Russian science and particularly its military sector in international cooperation, an access of Russian high technologies to the world market, to draw foreign investments for support of Russian science and participation in taking decision in the sphere od science, engineering and economy. All these measures need creation of new legislation for ensuring scientific and technical activity

Science affects multiple basic sectors of society. Therefore, the findings made in science impact what takes place at a commercial level. More specifically, errors in the literature, incorrect findings, fraudulent data, poorly written scientific reports, or studies that cannot be reproduced not only serve as a burden on tax-payers' money, but they also serve to diminish public trust in science and its findings. Therefore, there is every need to fortify the validity of data that exists in the science literature, not only to build trust among peers, and to sustain that trust, but to reestablish trust in the public and private academic sectors that are witnessing a veritable battle-ground in the world of science publishing, in some ways spurred by the rapid evolution of the open access (OA) movement. Even though many science journals, traditional and OA, claim to be peer reviewed, the truth is that different levels of peer review occur, and in some cases no, insufficient, or pseudo-peer review takes place. This ultimately leads to the erosion of quality and importance of science, allowing essentially anything to become published, provided that an outlet can be found. In some cases, predatory OA journals serve this purpose, allowing papers to be published, often without any peer review or quality control. In the light of an explosion of such cases in predatory OA publishing, and in severe inefficiencies and possible bias in the peer review of even respectable science journals, as evidenced by the increasing attention given to retractions, there is an urgent need to reform the way in which authors, editors, and publishers conduct the first line of quality control, the peer review. One way to address the problem is through post-publication peer review (PPPR), an efficient complement to traditional peer-review that allows for the continuous improvement and strengthening of the quality of science publishing. PPPR may also serve as a way to renew trust in scientific

Learning requires application of such processes as planning, supervision, monitoring and reflection that are included in the metacognition. Studies have shown that metacognition is associated with problem solving skills. The current research was conducted to investigate the impact of metacognitive instruction on students' problem solving skills. The study sample included 40 students studying in the second semester at Kermanshah University of Medical Sciences, 2013-2014. They were selected through convenience sampling technique and were randomly assigned into two equal groups of experimental and control. For the experimental group, problem solving skills were taught through metacognitive instruction during ten two-hour sessions and for the control group, problem solving skills were taught via conventional teaching method. The instrument for data collection included problem solving inventory (Heppner, 1988), which was administered before and after instruction. The validity and reliability of the questionnaire had been previously confirmed. The collected data were analyzed by descriptive statistics, mean and standard deviation and the hypotheses were tested by t-test and ANCOVA. The findings of the posttest showed that the total mean scores of problem solving skills in the experimental and control groups were 151.90 and 101.65, respectively, indicating a significant difference between them (pproblem solving skills and its components, including problem solving confidence, orientation-avoidance coping style and personal control (pproblem solving skills and is required to enhance academic achievement, metacognitive strategies are recommended to be taught to the students.

Full Text Available The article is devoted to geography of economic science, which is, according to the authors, a kind of a «gray zone», where concepts and methods of science of science, economic geography and economy cross. The authors proceeded from the following methodological prerequisites: 1 the production of economic knowledge is the activity, the scope and the results of which can be measured fairly accurately; 2 the structure of economic science can be presented not only as a sectoral, thematic, institutional, but also as a spatial. As an information base of research the authors used E-library resources which are relevant to the authors that have published the results of studies in Economics and related disciplines in the scientific journals. At the initial stage of the research, the authors focused on the economists who are employees of scientific research organizations (academic institutions, universities and research institutes that are located within the Russian Far East, as well as researchers from other regions of Russia, who have published articles in the Far Eastern scientific journals. Preliminary results of the study show following: 1 the high level of A.N. Demyanenko, N.A. Demyanenko PE No. 1 2014 territorial concentration (85% of all publications belongs to research organizations of Khabarovsk and Vladivostok; 2 the high level of information concentration (up to 90% of all publications belongs to Far Eastern journals.

Full Text Available Background and objective: Studies have indicated that metacognitive strategies control and direct cognitive strategies. Thus, application of metacognitive and cognitive strategies together is essential for successful learning to happen. The present study was conducted to examine the effect of metacognitive-oriented instruction on development of problem solving skills in students of Kermanshah University of Medical Sciences. Materials and Methods: This study was a quasi-experimental research with pretest/posttest and control group design. The study sample included the students of Kermanshah University of Medical Sciences (n=4283 in the academic year of 2013-2014. A total number of 40 students were selected through convenient sampling method as the study sample. The samples were randomly placed in experimental and control groups. For the experimental group, problem solving skills were taught based on metacognitive strategies in 8 sessions, each session for 1 and half hours. For the control group, however, problem solving skills were taught through conventional teaching method. The instrument for data collection was Heppner’s problem solving inventory (1988 whose validity and reliability were confirmed previously. Data were analyzed by descriptive statistics, mean and standard deviation, and the hypotheses were tested through t-test. Results: The results of the posttest showed that the total mean of scores for problem solving skills in the experimental group (99.75 was higher than that of the control group (26.800 (p<0.0001. This difference was significant in the case of confidence, approach/avoidance and personal control components (p<0.0001. Moreover, the mean of students’ scores was not significant in terms of gender and major. Conclusion: Given the positive effect of metacognitive strategies on the students’ performance and the necessity of teaching metacognition for the sake of academic achievement, these strategies are recommended to be

Polifonie en kontrapunt: Meganismes van verleiding in die dagboeke van Helen Hessel en Henri Pierre Roché. Henri Pierre Roché (1879–1959, outeur van Jules et Jim, word beskryf as ‘n sosiale koppelaar, ‘n model-liefhebber van alles en nog wat, ‘n versamelaar van vroue en kuns en een van die mees produktiewe dagboekskrywers en aktiewe minnaars in die opgetekende geskiedenis. Roché het ‘n reeks sketse oor Don Juan gepubliseer en was geboei deur die figuur van die verleier. In sy twintigs beplan hy om sy lewe te wy aan die skepping van ‘n œuvre wat die morele, intellektuele, sosiale en seksuele verhoudings tussen mans en vrouens sou ondersoek. Ter bereiking van hierdie doel, rig hy sy lewe in as laboratorium waarin werklike ondervindinge dien as hoofbron van inligting. Sy dagboek strek oor sestig jaar en is ryk aan verhale van verleiding. Desnieteenstaande bly die mees intense en boeiende intrige van verleiding en verraad steeds sy verhouding met Helen Hessel. Aan die begin van hulle verhouding, stel Roché voor dat sy ook ‘n dagboek hou van hulle hartstogtelike liefde. Helen Hessel se dagboek, geskryf in Frans, Duits en Engels, reflekteer die drama van verleiding en funksioneer op verskillende vlakke: realisties, visionêr, ten volle geabsorbeer in haar eie gedagtes en emosies en tóg krities jeens haarself en ander. ‘n Vergelyking van die twee dagboeke skep ‘n fassinerende, digte tekstuur wat die binnewerkings blootlê van verleiding in aksie. Die kontrapunt geskep deur hierdie twee interafhanklike stemme word nóg meer kompleks namate ‘n mens bewus word van die intertekstuele verwysings wat bydra tot die ontluikende polifonie van geskrewe liefde en lewe.

2012-01-01
上、中、下三部的《亨利六世》是莎士比亚戏剧中最长的，也是最优秀的剧作之一，然而这部剧作却常常被莎学家们忽略，特别是亨利六世这位被描写成以宗教原则来处理政事的国王也同样受到误解。但《亨利六世》对历史深邃的理解、对民族强烈的热爱、对人性深刻的洞察，特别是以宗教伦理原则对王位的反思更是让今日的读者产生无限的沉思与遐想。%Henry VI, a history play by William Shakespeare which firmly establishes his reputa- tion as a playwright, is often neglected by modern critics. Henry VI as the king who governs the realm of England not by law but by religious ethics is also misinterpreted by some Shakespeareans. However, with the profound understanding of history, the devotion to the coun- try, the insight into humanity, and especially the untimely King Henry VI' s reflections on his reign, this history play provides present-day readers with unlimited contemplation and imagina- tion.

Comparison of PASCAL and FORTRAN for solving problems in the physical sciences
Watson, V. R.
1981-01-01
The paper compares PASCAL and FORTRAN for problem solving in the physical sciences, due to requests NASA has received to make PASCAL available on the Numerical Aerodynamic Simulator (scheduled to be operational in 1986). PASCAL disadvantages include the lack of scientific utility procedures equivalent to the IBM scientific subroutine package or the IMSL package which are available in FORTRAN. Advantages include a well-organized, easy to read and maintain writing code, range checking to prevent errors, and a broad selection of data types. It is concluded that FORTRAN may be the better language, although ADA (patterned after PASCAL) may surpass FORTRAN due to its ability to add complex and vector math, and the specify the precision and range of variables.

The historiography of contemporary science, technology, and medicine writing recent science
Söderqvist, Thomas
2006-01-01
As historians of science increasingly turn to work on recent (post 1945) science, the historiographical and methodological problems associated with the history of contemporary science are debated with growing frequency and urgency. Bringing together authorities on the history, historiography and methodology of recent and contemporary science, this book reviews the problems facing historians of technology, contemporary science and medicine, and explores new ways forward. With contributions from key researchers in the field, the text covers topics that will be of ever increasing interest to historians of post-war science, including the difficulties of accessing and using secret archival material, the interactions between archivists, historians and scientists, and the politics of evidence and historical accounts.

We implemented a NOS and HOS-enriched Problem-Based Learning environment at the middle (year 7 of the Portuguese National Curriculum and secondary level (year 10 for teaching the origins of biodiversity and of continents and oceans (mobilism. The goal of providing detailed implementation practices is to adress the lack of how to in Problem-based learning (PBL implementation in classrooms for 12 to 16 year old students and is the first practical example of implementation using this episode of HOS for teaching geological mobilism integrated with evolution. Therefore, in this study, we provide specific suggestions for supporting teachers’ classroom efforts in implementing PBL, such as scaffolding. The ill-problem presented to students, without a single correct answer, was based on the phylogeny of extant and extinct ratite birds, described by Charles Darwin and the present geographical distribution. The evaluation of the students was focused on the chain of reasoning employed, and we performed a comparisation analysis of the problem’s solution presented by the students of both classes regarding the explanation of the phylogeny of ratites based on geological mobilism. We observed an overall improvement (25-77% of the percentages of students pre- and post-instruction adequate answers; therefore our PBL strategy was efficient.

Plasma experiments elucidative for challenging problems investigated in other branches of science
International Nuclear Information System (INIS)
Sanduloviciu, M.; Popescu, S.
2001-01-01
Driving away from thermal equilibrium a plasma initially in an asymptotic stable state it is possible to identify the succession of the physical processes that form, as a whole, a new scenario of self-organization able to explain, besides the challenging problems of non-equilibrium physics, also some of the today not solved essential problems of the chemical and biological sciences. Thus, plasma experiments have revealed the presence of a local self-enhancement mechanism associated with long-range inhibition that explains pattern formation in general. Two successively produced instabilities originated in a positive feedback mechanism were identified to be at the origin of the spatial and spatial-temporal patterns, respectively. This feedback mechanism comprises a self-enhancing mechanism of the production of positive ions complemented by the creation of a net negative space charge by accumulation of electrons that have lost their kinetic energy in neutral excitations. The informational content concerning self-organization revealed by the plasma experiments suggests the presence of a new physical basis for the behavior of the systems working as differential negative resistance, but also new information on the actual cause of the anomalous transport of particles and energy. These results present special interest in solid state physics where the mechanism of current instabilities observed in semiconductors is today a non-conclusively solved problem. Anomalous transport of particles and energy is today a challenging problem of high energy physics because it is considered as the principal cause that impedes the improvement of the economical performances of fusion devices. Since all chemical and biological phenomena involve, at least, physical processes, the scenario of self-organization identified in plasma could be elucidative for understanding the phenomena, as for instance, the pattern formation in chemical media, but also the spontaneous self-assembling of the

Peters, John S.
This study used a multiple response model (MRM) on selected items from the Views on Science-Technology-Society (VOSTS) survey to examine science-technology-society (STS) literacy among college non-science majors' taught using Problem/Case Studies Based Learning (PBL/CSBL) and traditional expository methods of instruction. An initial pilot investigation of 15 VOSTS items produced a valid and reliable scoring model which can be used to quantitatively assess student literacy on a variety of STS topics deemed important for informed civic engagement in science related social and environmental issues. The new scoring model allows for the use of parametric inferential statistics to test hypotheses about factors influencing STS literacy. The follow-up cross-institutional study comparing teaching methods employed Hierarchical Linear Modeling (HLM) to model the efficiency and equitability of instructional methods on STS literacy. A cluster analysis was also used to compare pre and post course patterns of student views on the set of positions expressed within VOSTS items. HLM analysis revealed significantly higher instructional efficiency in the PBL/CSBL study group for 4 of the 35 STS attitude indices (characterization of media vs. school science; tentativeness of scientific models; cultural influences on scientific research), and more equitable effects of traditional instruction on one attitude index (interdependence of science and technology). Cluster analysis revealed generally stable patterns of pre to post course views across study groups, but also revealed possible teaching method effects on the relationship between the views expressed within VOSTS items with respect to (1) interdependency of science and technology; (2) anti-technology; (3) socioscientific decision-making; (4) scientific/technological solutions to environmental problems; (5) usefulness of school vs. media characterizations of science; (6) social constructivist vs. objectivist views of theories; (7

Teaching science problem based learning (PBL) implementation of rocks and minerals
Almeida, Carla; Ruas, Fátima; Godinho, Margarida; Martins, Anabela
2016-04-01
Problem Based Learning (PBL) is a teaching methodology based on the Inquiry Teaching approach, which consists of finding a solution to a problem that requires the use of higher-level cognitive skills. It's best carried out in small groups. (I) First the teacher asks some questions related to the implementation of rocks and minerals in the schooĺs area and in our life. (II) Then the teacher leads students to an area of the city (Avenida dos Aliados - Porto) and asks them to look at the buildings and the objects there are. They should take pictures and notes. (III) Finally, in the classroom, the teacher gives an object (phone, CD, lamp, lipstick, dish/cup, etc.) to each group and asks them to do a research to find out what materials they contain or are made of. The teacher helps students to think about where and how they can find information about the subject. Students should proceed with their research by presenting the results to their colleagues, discussing in groups, doing brainstorming and collaborating in the learning process. After the discussion the students must present their conclusions. The main aims are: to report some applications of rocks in society; to recognize the rocks used in some buildings of the region where the school is located; to respect and preserve the traditional architecture of the rocks in each region; and to raise awareness among young people about environmental issues of preservation and sustainability of our planet. The teacher finishes the lesson, asking some other questions: Will it be possible to use the natural resources of other planets? Can human beings use them to their advantage? This educational approach motivates students towards science, helping them to solve problems from their daily life and in collaborative work. The cognitive strand continues to be the most valued for pupils.

Science and management of coral reefs: problems and prospects
Wells, S. M.
1995-11-01
It should be recognised that many principles of reef management do not need further research, as they involve changing human behaviour and activities in order to remove or reduce impacts on reefs. Much of the time of a reef manager is taken up with social, economic and political issues: the integration of reef management into broad coastal zone management objectives; the development of community participation and co-management; and the organisation of training and education pro-grammes so that people in countries where reefs are located are able to take responsibility for their sustainable management. Perhaps the main obstacle to be overcome is poor communication (Harmon 1994). Many reef scientists are already strongly convinced of the need to communicate their results and the implications of these for management and conservation policy (Hatcher et al. 1989), but they may however need to understand that reef managers are not always able or willing to act on their advice because of political, economic or social factors. Pure research is increasingly being conducted within a framework of goals identified as important to society. Funding is invariably easier to obtain if it can be demonstrated that the research will have some ultimate benefit in management terms, and much research is being commissioned because of the need for practical solutions. As the complexity of management becomes more apparent and managers themselves call for more scientific support and advice, the role that science has to play in perceiving and defining problems, understanding the mechanisms involved and strategically assessing potential solutions, becomes more central. Often, only a slight adjustment to a project is required in order for data to be collected that is of direct value to a reef manager.Partnerships built between scientists and managers engaged in adaptive management efforts may lead to more rapid progress in managing reefs and may banish the `science and management' dichotomy

Henry Moore’s Public Sculpture in the US: The Collaborations with I. M. Pei
Directory of Open Access Journals (Sweden)
Alex Potts
2016-07-01
Full Text Available The many commissions Henry Moore received for public sculpture in the United States provided the occasion for several quite distinctive works. While not site specific, these were unique, and their final form, scale, and disposition was elaborated with a particular setting in mind. This aspect of Moore’s work in the US, which began with the monumental piece he designed for the Lincoln Center in New York in 1963–65, is examined here by focusing on the productive relationship he forged with the architect I. M. Pei in the 1970s. The sculptures Moore produced in collaboration with Pei respond in suggestive ways to the spatial environments created in American cities by late modern architectural developments. They also realize an oddly effective combination of the biomorphic and abstract that differs both from the bodily conception of Moore’s earlier work and the non-figurative character of much public sculpture of the time.

Henry Fayol’s 14 Principles of Management: Implications for Libraries and Information Centres
Directory of Open Access Journals (Sweden)
Uzuegbu, C. P.
2015-06-01
Full Text Available This paper focuses generally on the ‘fourteen principles of management’ by Henri Fayol. However, it specifically analyses their application to and implications for libraries and information centres. An extensive review of published works on management generally, and library management in particular, was conducted. This yielded vital insights on the original meaning and later modifications of these principles, as well as their application in the management of various organisations. Consequently, the strengths and weaknesses of these principles were examined to determine their suitability in libraries and information centres. Inferences, illustrations, and examples were drawn from both developed and developing countries which gives the paper a global perspective. Based on available literature, it was concluded that Fayol’s principles of management are as relevant to libraries as they are in other organisations. The paper, therefore, recommends that in addition to modifying some aspects to make these principles more responsive to the peculiar needs of libraries, further research should be undertaken to expand the breadth of these principles and ascertain their impacts on the management of information organisations.

Modeling biological problems in computer science: a case study in genome assembly.
Medvedev, Paul
2018-01-30
As computer scientists working in bioinformatics/computational biology, we often face the challenge of coming up with an algorithm to answer a biological question. This occurs in many areas, such as variant calling, alignment and assembly. In this tutorial, we use the example of the genome assembly problem to demonstrate how to go from a question in the biological realm to a solution in the computer science realm. We show the modeling process step-by-step, including all the intermediate failed attempts. Please note this is not an introduction to how genome assembly algorithms work and, if treated as such, would be incomplete and unnecessarily long-winded. © The Author(s) 2018.

This research was carried out over a period of ten months with children in Grades 2 and 3 (aged 7 and 8) who were participating in a sequence of technology activities. Since the introduction into Victorian primary schools of The Technology Studies Framework P-10 (Crawford, 1988), more teachers are including technology studies in their classrooms and by so doing may assist children's understanding of science concepts. Children are being exposed to science phenomena related to the technology activities and Technology Studies may be a way of providing children with science experiences. ‘Technology Studies’ in this context refers to children carrying out practical problem solving tasks which can be completed without any particular scientific knowledge. Participation in the technology activities may encourage children to become actively involved, thereby facilitating an exploration of the related science concepts. The project identified the importance of challenge in relation to the children's involvement in the technology activities and the conference paper (available from the first author) discusses particular topics in terms of the balance between cognitive/metacognitive and affective influences (Baird et al., 1990)

Full Text Available During the period following 1873, when Bessarabia was a province of the Russian Empire, the architecture of this period was dominated by a mixture of several historical styles and directions, the so-called “eclectic” stage. The creativity of leading architects such as Alexander Bernardazzi and Henry Lonsky was the most evident at that time. The image of the city of Kishinev became more eclectic and it was reflected in the buildings of the railway station and the passenger hall, the city club, the county court, the Noble Assembly, the winemaking school, all of which were built according to the designs of these architects in the second half of the XIX century. At that time, a question relative to the necessity of new theatre building in Kishinev was of a particular interest. In 1889 the Kishinev City Head Karl Schmidt proposed to construct a temporary theatre with beautiful facade, together with the fact that in size it could satisfy the needs of city for the next 15-20 years. And he appealed to the city architects, including A. Bernardazzi and H. Lonsky to present their views at this important problem. The author writes this article on the basis of the archival documents which present the history of the construction of various buildings and the creative activity of the architects. This is reflected through the prism of that era with a high level of development and methods of construction equipment, as well as with the artistic principles characteristic of that period.

Resumo Este artigo propõe uma análise comparativa entre textos de caráter autobiográfico do intelectual e político brasileiro Joaquim Nabuco e do escritor norte-americano Henry James, nos quais eles modelam suas subjetividades e confrontam-se com alguns dos problemas que mobilizaram boa parte dos intelectuais, na virada do século XIX para o XX. Tanto Minha formação (1900), de Nabuco, quanto The American scene (1907), de James, representam o sentimento a que Evaldo Cabral de Mello chama "o dil...

require and challenge interdisciplinarity. Problem: The conventional methods of interdisciplinary research fall short in the case of wicked problems because they remain first-order science. Our aim is to present workable methods and research designs for doing second-order science in domains where...... there are many different scientific knowledges on any complex problem. Method: We synthesize and elaborate a framework for second-order science in interdisciplinary research based on a number of earlier publications, experiences from large interdisciplinary research projects, and a perspectivist theory...... of science. Results: The second-order polyocular framework for interdisciplinary research is characterized by five principles. Second-order science of interdisciplinary research must: 1. draw on the observations of first-order perspectives, 2. address a shared dynamical object, 3. establish a shared problem...

Combining control theory and modeling, this textbook introduces and builds on methods for simulating and tackling concrete problems in a variety of applied sciences. Emphasizing "learning by doing," the authors focus on examples and applications to real-world problems. An elementary presentation of advanced concepts, proofs to introduce new ideas, and carefully presented MATLAB(R) programs help foster an understanding of the basics, but also lead the way to new, independent research. With minimal prerequisites and exercises in each chapter, this work serves as an excellent textbook a

Full Text Available While the utility of concept mapping has been widely reported in primary and secondary educational contexts, its application in the health sciences in higher education has been less frequently noted. Two case studies of the application of concept mapping in undergraduate and postgraduate health sciences are detailed in this paper. The case in undergraduate dental education examines the role of concept mapping in supporting problem-based learning and explores how explicit induction into the principles and practices of CM has add-on benefits to learning in an inquiry-based curriculum. The case in postgraduate medical education describes the utility of concept mapping in an online inquiry-based module design. Specific attention is given to applications of CMapTools™ software to support the implementation of Novakian concept mapping in both inquiry-based curricular contexts.

Utilizing a logic model to identify clinical research problems: a lesson from philosophy of science
Directory of Open Access Journals (Sweden)
Collins CR
2016-10-01
Full Text Available Cynthia R Collins School of Nursing, College of Social Sciences, Loyola University, New Orleans, LA, USA Abstract: Communication and decision making in the health care workplace often involve finding solutions to ill-structured problems in uncertain, dynamic environments influenced by the competing interests of multiple stakeholders. In this environment, doctoral-prepared nurses who practice as administrators, policy makers, or advanced practice practitioners are often compelled to make important decisions based upon evaluating the merit of colleagues’ proposals against some desired organizational or population outcome. Of equal importance is the nurse leader’s own capacity to construct a compelling argument or proposal that will drive the organization forward to meet the evolving needs for quality health care. Where do we learn the skills necessary to foster this kind of critical thinking in our professional communications? The author suggests that one teaching–learning approach can be found through the thoughtful application of the work of British philosopher Steven Toulmin. Toulmin defined a model for both the analysis and derivation of logical arguments or proposals that can be readily learned and applied for use in health care systems. This model posits that a substantive argument or claim can be evaluated based on the assumptions it presumes (warrants and the strength of the evidence base (backing. Several of the social science professions have adapted Toulmin’s model to generate analysis and creative solutions to complex or emergent problems. The author proposes that an application of this model be included in the pedagogy of doctoral level Philosophy of Science or Nursing Theory courses. The Toulmin process often provides the doctoral student or novice researcher with their first real learning experience in defining the scope and inherent challenges of framing a clinical issue to be the focus of their scholarly translational

[Application of problem-based learning in teaching practice of Science of Meridians and Acupoints].
Wang, Xiaoyan; Tang, Jiqin; Ying, Zhenhao; Zhang, Yongchen
2015-02-01
Science of Meridians and Acupoints is the bridge between basic medicine and clinical medicine of acupuncture and moxibustion. This teaching practice was conducted in reference to the teaching mode of problembased learning (PBL), in association with the clinical design problems, by taking as the students as the role and guided by teachers. In order to stimulate students' active learning enthusiasm, the writers implemented the class teaching in views of the typical questions of clinical design, presentation of study group, emphasis on drawing meridian running courses and acupoint locations, summarization and analysis, as well as comprehensive evaluation so that the comprehensive innovative ability of students and the teaching quality could be improved.

Science As A Second Language: Acquiring Fluency through Science Enterprises
Shope, R.; EcoVoices Expedition Team
2013-05-01
Science Enterprises are problems that students genuinely want to solve, questions that students genuinely want to answer, that naturally entail reading, writing, investigation, and discussion. Engaging students in personally-relevant science enterprises provides both a diagnostic opportunity and a context for providing students the comprehensible input they need. We can differentiate instruction by creating science enterprise zones that are set up for the incremental increase in challenge for the students. Comprehensible input makes reachable, those just-out-of-reach concepts in the mix of the familiar and the new. EcoVoices takes students on field research expeditions within an urban natural area, the San Gabriel River Discovery Center. This project engages students in science enterprises focused on understanding ecosystems, ecosystem services, and the dynamics of climate change. A sister program, EcoVoces, has been launched in Mexico, in collaboration with the Universidad Loyola del Pacífico. 1) The ED3U Science Inquiry Model, a learning cycle model that accounts for conceptual change: Explore { Diagnose, Design, Discuss } Use. 2) The ¿NQUIRY Wheel, a compass of scientific inquiry strategies; 3) Inquiry Science Expeditions, a way of laying out a science learning environment, emulating a field and lab research collaboratory; 4) The Science Educative Experience Scale, a diagnostic measure of the quality of the science learning experience; and 5) Mimedia de la Ciencia, participatory enactment of science concepts using techniques of mime and improvisational theater. BACKGROUND: Science has become a vehicle for teaching reading, writing, and other communication skills, across the curriculum. This new emphasis creates renewed motivation for Scientists and Science Educators to work collaboratively to explore the common ground between acquiring science understanding and language acquisition theory. Language Acquisition is an informal process that occurs in the midst of

A call for more science in forensic science.
Bell, Suzanne; Sah, Sunita; Albright, Thomas D; Gates, S James; Denton, M Bonner; Casadevall, Arturo
2018-05-01
Forensic science is critical to the administration of justice. The discipline of forensic science is remarkably complex and includes methodologies ranging from DNA analysis to chemical composition to pattern recognition. Many forensic practices developed under the auspices of law enforcement and were vetted primarily by the legal system rather than being subjected to scientific scrutiny and empirical testing. Beginning in the 1990s, exonerations based on DNA-related methods revealed problems with some forensic disciplines, leading to calls for major reforms. This process generated a National Academy of Science report in 2009 that was highly critical of many forensic practices and eventually led to the establishment of the National Commission for Forensic Science (NCFS) in 2013. The NCFS was a deliberative body that catalyzed communication between nonforensic scientists, forensic scientists, and other stakeholders in the legal community. In 2017, despite continuing problems with forensic science, the Department of Justice terminated the NCFS. Just when forensic science needs the most support, it is getting the least. We urge the larger scientific community to come to the aid of our forensic colleagues by advocating for urgently needed research, testing, and financial support.

The aim of this research is to produce SAS based on MI and problem-solving skills using simple science tools that are suitable to be used by elementary school students. The feasibility of SAS is evaluated based on its validity, practicality, and effectiveness. The completion Lesson Plan (LP) implementation and student’s activities are the indicators of SAS practicality. The effectiveness of SAS is measured by indicators of increased learning outcomes and problem-solving skills. The development of SAS follows the 4-D (define, design, develop, and disseminate) phase. However, this study was done until the third stage (develop). The written SAS was then validated through expert evaluation done by two experts of science, before its is tested to the target students. The try-out of SAS used one group with pre-test and post-test design. The result of this research shows that SAS is valid with “good” category. In addition, SAS is considered practical as seen from the increase of student activity at each meeting and LP implementation. Moreover, it was considered effective due to the significant difference between pre-test and post-test result of the learning outcomes and problem-solving skill test. Therefore, SAS is feasible to be used in learning.

El urbanismo contra lo urbano. La ciudad y la vida urbana en Henri Lefebvre
Directory of Open Access Journals (Sweden)
Manuel Delgado Ruiz
2018-01-01
Full Text Available Henri Lefebvre coloca en el eje de su teoría sobre la vida urbana la oposición entre el espacio vivido por quienes lo usan o sueñan y el espacio abstracto que creen organizar los tecnócratas de la ciudad, que raramente reconocen hasta qué punto su “creatividad” está sometida a intereses privados o institucionales. Tras ese espacio hipotético sobre el que urbanistas y arquitectos trabajan no hay otra cosa que mera ideología, es decir, fantasma que recubre y disfraza las relaciones sociales reales de producción. Frente -o de espaldas- a ese orden espacial meramente teórico de los “especialistas”, lo que las ciudades conocen es la actividad constante o inminente de lo urbano, entendido como apoteosis y exacerbación de lo social, dinamismo siempre activado de acontecimientos y quehaceres sobre el que los “expertos” aplican planes y proyectos, pero del que no saben en realidad nada, acaso por lo cual pugnan por anularlo.

Full Text Available A series of MgAl-layered double hydroxide (MgAl-HT, the calcined form at 500 °C (MgAlOx, and the rehydrated one at 25 °C (MgAl-HT-RH were synthesized. Physicochemical properties of the catalysts were characterized by X-ray diffraction (XRD and scanning electron microscopy (SEM. Surface area of the as-synthesized, calcined, and rehydrated catalysts was determined by N2 physisorption at −196 °C. CO2 temperature-programmed desorption (CO2-TPD was applied to determine the basic sites of catalysts. The catalytic test reaction was carried out using benzaldehyde and their derivatives with nitromethane and their derivatives. The Henry products (1–15 were obtained in a very good yield using MgAl-HT-RH catalyst either by conventional method at 90 °C in liquid phase or under microwave irradiation method. The mesoporous structure and basic nature of the rehydrated solid catalyst were responsible for its superior catalytic efficiency. The robust nature was determined by using the same catalyst five times, where the product % yield was almost unchanged significantly.

Derivation of the MMPI-2-RF Henry-Heilbronner Index-r (HHI-r) scale.
Henry, George K; Heilbronner, Robert L; Algina, James; Kaya, Yasemin
2013-01-01
The 15-item Henry-Heilbronner Index (HHI) was published in 2006 as an MMPI-2 embedded measure of psychological response validity. When the MMPI-2 was revised in 2008 only 11 of the 15 original HHI items were retained on the MMPI-2-RF, prohibiting use of the HHI as an embedded validity indicator on the MMPI-2-RF. Using the original HHI sample an 11-item version of the HHI, the HHI-r, was evaluated for use as an embedded measure of psychological response validity for the MMPI-2-RF. The 11-item HHI-r was very similar to the HHI in classification accuracy. An HHI-r cutoff score of ≥7 was associated with a classification accuracy rate of 84.0%, good sensitivity (68.9%), and high specificity (93.2%) in identifying symptom exaggeration in personal injury and disability litigants versus non-litigating head-injured patients. These preliminary results suggest the HHI-r functions in a manner similar to the original HHI as a measure of psychological response validity, and may be used by psychologists and neuropsychologists as an MMPI-2-RF embedded validity indicator.

Full Text Available From October 1965 to May 1966, the Science Museum in London displayed the American spacecraft Freedom 7, the first capsule in NASA’s Mercury programme to take a human on a suborbital flight. Archival records concerning this temporary display are extensive and contain photographic sources as well as written ones. This case therefore lends itself to a study aimed at evaluating the comparative merits of these two types of records, for understanding the logic at play in the display, and for retrieving at least part of the visitors’ experience. Visual sources emerge from this comparison as invaluable records for accessing the materiality of this temporary exhibition. They demonstrate that the Freedom 7 special exhibition was a key moment in the establishment of a space science and technology section at the Science Museum, as it enabled the Museum to begin historicising what was then a new field of scientific and technological enquiry. The exhibition follows a logic of display theorised in 1950 by Henry Calvert, a senior curator, in a note recently discovered in the Science Museum’s archives. It is based on the display of a star object that draws visitors’ attention towards less charismatic exhibits.

Poincaré, Henri
2017-01-01
Here is an accurate and readable translation of a seminal article by Henri Poincaré that is a classic in the study of dynamical systems popularly called chaos theory. In an effort to understand the stability of orbits in the solar system, Poincaré applied a Hamiltonian formulation to the equations of planetary motion and studied these differential equations in the limited case of three bodies to arrive at properties of the equations’ solutions, such as orbital resonances and horseshoe orbits. Poincaré wrote for professional mathematicians and astronomers interested in celestial mechanics and differential equations. Contemporary historians of math or science and researchers in dynamical systems and planetary motion with an interest in the origin or history of their field will find his work fascinating. .

A Survey on Inverse Problems for Applied Sciences
Directory of Open Access Journals (Sweden)
Fatih Yaman
2013-01-01
Full Text Available The aim of this paper is to introduce inversion-based engineering applications and to investigate some of the important ones from mathematical point of view. To do this we employ acoustic, electromagnetic, and elastic waves for presenting different types of inverse problems. More specifically, we first study location, shape, and boundary parameter reconstruction algorithms for the inaccessible targets in acoustics. The inverse problems for the time-dependent differential equations of isotropic and anisotropic elasticity are reviewed in the following section of the paper. These problems were the objects of the study by many authors in the last several decades. The physical interpretations for almost all of these problems are given, and the geophysical applications for some of them are described. In our last section, an introduction with many links into the literature is given for modern algorithms which combine techniques from classical inverse problems with stochastic tools into ensemble methods both for data assimilation as well as for forecasting.

Current Status of Regulatory Science Education in Faculties of Pharmaceutical Science in Japan.
Tohkin, Masahiro
2017-01-01
I introduce the current pharmaceutical education system in Japan, focusing on regulatory science. University schools or faculties of pharmaceutical science in Japan offer two courses: a six-year course for pharmacists and a four-year course for scientists and technicians. Students in the six-year pharmaceutical course receive training in hospitals and pharmacies during their fifth year, and those in the four-year life science course start research activities during their third year. The current model core curriculum for pharmaceutical education requires them to "explain the necessity and significance of regulatory science" as a specific behavior object. This means that pharmacists should understand the significance of "regulatory science", which will lead to the proper use of pharmaceuticals in clinical practice. Most regulatory science laboratories are in the university schools or faculties of pharmaceutical sciences; however, there are too few to conduct regulatory science education. There are many problems in regulatory science education, and I hope that those problems will be resolved not only by university-based regulatory science researchers but also by those from the pharmaceutical industry and regulatory authorities.

Science Fairs and Observational Science: A Case History from Earth Orbit
Lowman, Paul D., Jr.; Smith, David E. (Technical Monitor)
2002-01-01
Having judged dozens of science fairs over the years, I am repeatedly disturbed by the ground rules under which students must prepare their entries. They are almost invariably required to follow the "scientific method," involving formulating a hypothesis, a test of the hypothesis, and then a project in which this test is carried out. As a research scientist for over 40 years, I consider this approach to science fairs fundamentally unsound. It is not only too restrictive, but actually avoids the most important (and difficult) part of scientific research: recognizing a scientific problem in the first place. A well-known example is one of the problems that, by his own account, stimulated Einstein's theory of special relativity: the obvious fact that when an electric current is induced in a conductor by a magnetic field , it makes no difference whether the field or the conductor is actually (so to speak) moving. There is in other words no such thing as absolute motion. Physics was transformed by Einstein's recognition of a problem. Most competent scientists can solve problems after they have been recognized and a hypothesis properly formulated, but the ability to find problems in the first Place is much rarer. Getting down to specifics, the "scientific method" under which almost all students must operate is actually the experimental method, involving controlled variables, one of which, ideally, is changed at a time. However, there is another type of science that can be called observational science. As it happens, almost all the space research I have carried out since 1959 has been this type, not experimental science.

Full Text Available Science education is progressively more focused on employing inquiry-based learning methods in the classroom and increasing scientific literacy among students. However, due to time and resource constraints, many classroom science activities and laboratory experiments focus on simple inquiry, with a step-by-step approach to reach predetermined outcomes. The science classroom inquiry (SCI simulations were designed to give students real life, authentic science experiences within the confines of a typical classroom. The SCI simulations allow students to engage with a science problem in a meaningful, inquiry-based manner. Three discrete SCI simulations were created as website applications for use with middle school and high school students. For each simulation, students were tasked with solving a scientific problem through investigation and hypothesis testing. After completion of the simulation, 67% of students reported a change in how they perceived authentic science practices, specifically related to the complex and dynamic nature of scientific research and how scientists approach problems. Moreover, 80% of the students who did not report a change in how they viewed the practice of science indicated that the simulation confirmed or strengthened their prior understanding. Additionally, we found a statistically significant positive correlation between students' self-reported changes in understanding of authentic science practices and the degree to which each simulation benefitted learning. Since SCI simulations were effective in promoting both student learning and student understanding of authentic science practices with both middle and high school students, we propose that SCI simulations are a valuable and versatile technology that can be used to educate and inspire a wide range of science students on the real-world complexities inherent in scientific study.

The U.S. Department of Energy (DOE) is a world leader in the development of high-performance computing (HPC), the development of applied math and algorithms that utilize the full potential of HPC platforms, and the application of computing to science and engineering problems. An interesting general question is whether the DOE can strategically utilize its capability in simulations to advance innovation more broadly. In this article, I will argue that this is certainly possible.

The use of technology into science learning encounters problems. One of the problem is teachers’ less technological pedagogical and content knowledge (TPACK) on the implementation of technology itself. The purpose of this study was to investigate science teachers’ experience in using digital technology into science classroom. Through this study science teachers’ technological knowledge (TK) and technological content knowledge (TCK) can be unpacked. Descriptive method was used to depict science teachers’ TK and TCK through questionnaire that consisted of 20 questions. Subjects of this study were 25 science teachers in Bandung, Indonesia. The study was conducted in the context of teacher professional training. Result shows that science teachers still have less TK, yet they have high TCK. The teachers consider characteristics of concepts as main aspect for implementing technology into science teaching. This finding describes teachers’ high technological content knowledge. Meanwhile, science teachers’ technological knowledge was found to be still low since only few of them who can exemplify digital technology that can be implemented into several science concept. Therefore, training about technology implementation into science teaching and learning is necessary as a means to improve teachers’ technological knowledge.

At the Faculty of Engineering and Science at Aalborg University, Denmark, process skills are an integrated part of the curriculum objectives. During the first year programme, a special course in Collaboration, Learning and Project Management (CLP) is given to develop those skills. In order...... to develop students’ learning and the CLP-course, the Felder-Soloman Index of Learning Styles (ILS®) has been used in that course and data has been collected to investigate whether some learning style preferences are more conspicuous that others in a problem based learning environment. The results show, more...... pronounced than similar studies, that the first year engineering students at Aalborg University are considerable more active than reflective. This results leads to a discussion of whether reflection and conceptualization should be facilitated further in the curriculum to balance the students learning style...

Adolescence is marked with many changes in the development of higher order thinking skills. As students enter high school they are expected to utilize these skills to solve problems, become abstract thinkers, and contribute to society. The goal of this study was to assess horticultural science knowledge achievement and attitude toward horticulture, science, and school in high school agriculture students. There were approximately 240 high school students in the sample including both experimental and control groups from California and Washington. Students in the experimental group participated in an educational program called "Hands-On Hortscience" which emphasized problem solving in investigation and experimentation activities with greenhouse plants, soilless media, and fertilizers. Students in the control group were taught by the subject matter method. The activities included in the Hands-On Hortscience curriculum were created to reinforce teaching the scientific method through the context of horticulture. The objectives included evaluating whether the students participating in the Hands-On Hortscience experimental group benefited in the areas of science literacy, data acquisition and analysis, and attitude toward horticulture, science, and school. Pre-tests were administered in both the experimental and control groups prior to the research activities and post-tests were administered after completion. The survey questionnaire included a biographical section and attitude survey. Significant increases in hortscience achievement were found from pre-test to post-test in both control and experimental study groups. The experimental treatment group had statistically higher achievement scores than the control group in the two areas tested: scientific method (p=0.0016) and horticulture plant nutrition (p=0.0004). In addition, the students participating in the Hands-On Hortscience activities had more positive attitudes toward horticulture, science, and school (p=0

In the early 1830s, the Philadelphia publisher Henry H. Porter rapidly published five journals, six books, and an almanac, works having a particular emphasis on health and personal hygiene. Porter's health publications linked the traditional message about the importance of personal hygiene to health to the messages conveyed by the flourishing American reform movements at the time, and his Journal of Health was among the first American medically oriented periodicals published for the layperson. Yet Porter did not survive in the intensely competitive and financially unstable book trade. This study examines Porter's health publications, attempting to explain why he chose to publish what he did, the message(s) his works contained, the audience(s) he tried to reach, and the failure of his business.

In the analysis of volatile organic compounds in air, the preparation of their gaseous standards at low (sub-ppb) concentration levels with high reliability is quite difficult. In this study, a simple dynamic headspace-based approach was evaluated as a means of generating vapor-phase volatile organic compounds from a liquid standard in an impinger at ambient temperature (25 °C). For a given sampling time, volatile organic compound vapor formed in the headspace was swept by bypassing the sweep gas through the impinger and collected four times in quick succession in separate sorbent tubes. In each experiment, a fresh liquid sample was used for each of the four sampling times (5, 10, 20, and 30 min) at a steady flow rate of 50 mL min(-1). The air-water partitioning at the most dynamic (earliest) sweeping stage was established initially in accord with ideal Henry's law, which was then followed by considerably reduced partitioning in a steady-state equilibrium (non-ideal Henry's law). The concentrations of gaseous volatile organic compounds, collected after the steady-state equilibrium, reached fairly constant values: for instance, the mole fraction of toluene measured at a sweeping interval of 10 and 30 min averaged 1.10 and 0.99 nmol mol(-1), respectively (after the initial 10 min sampling). In the second stage of our experiment, the effect of increasing the concentrations of liquid spiking standard was also examined by collecting sweep gas samples from two consecutive 10 min runs. The volatile organic compounds, collected in the first and second 10 min sweep gas samples, exhibited ideal and nonideal Henry's law behavior, respectively. From this observation, we established numerical relationships to predict the mole fraction (or mixing ratio) of each volatile organic compound in steady-state equilibrium in relation to the concentration of standard spiked into the system. This experimental approach can thus be used to produce sub-ppb levels of gaseous volatile organic

Some conception of international science-education center on nano science in Vladivostok is presented. The conception is based on internal and external prerequisites. Internal one is high intellectual potential of institutes of Russian Academy of Sciences and universities of Vladivostok and external one is need of countries of Far Eastern region of Asia in high level manpower. The conception takes into account a specific distribution of science and education potential between Russian Academy of Sciences and Russian universities and a specific their dislocation in Vladivostok. First specific dictates some similarity of organization structure and function of international science-education center to typical science-education center in Russia. But as for dislocation of the international science-education center in Vladivostok, it should be near dislocation of institutes of Far Eastern Brunch of Russian Academy of Sciences in Vladivostok, which are dislocated very compactly in suburb zone of Vladivostok

Science outside the laboratory measurement in field science and economics
Boumans, Marcel
2015-01-01
The conduct of most of social science occurs outside the laboratory. Such studies in field science explore phenomena that cannot for practical, technical, or ethical reasons be explored under controlled conditions. These phenomena cannot be fully isolated from their environment or investigated by manipulation or intervention. Yet measurement, including rigorous or clinical measurement, does provide analysts with a sound basis for discerning what occurs under field conditions, and why. In Science Outside the Laboratory, Marcel Boumans explores the state of measurement theory, its reliability, and the role expert judgment plays in field investigations from the perspective of the philosophy of science. Its discussion of the problems of passive observation, the calculus of observation, the two-model problem, and model-based consensus uses illustrations drawn primarily from economics. Rich in research and discussion, the volume clarifies the extent to which measurement provides valid information about objects an...

[How to distinguish science from non science].
Antiseri, D
1991-01-01
The questions discussed in this article concern the demarcation between scientific theories and non scientific theories. The problem is not only an epistemological one, but it implies also ethical and social consequences. For example, is it acceptable for an European country to allow the practice of non-traditional medicines which are not yet considered officially as scientific? According to Karl Popper, the author discusses the following points: 1. Is there a logical asymmetry between the verification and the falsification of a theory? 2. The criterion of falsifiability demarcates science from non-science. 3. There is no automatic method to find new theories. 4. The facts of science are discovered by scientists through theories. 5. The scientific method is only one and it consists of these three steps: problems-theories-refutations. The article's core is that the rational physician is the one who kills (falsifies) his own diagnosis instead of his own patients.

Henry's law constants and infinite dilution activity coefficients of cis-2-butene, dimethylether, chloroethane, and 1,1-difluoroethane in methanol, 1-propanol, 2-propanol, 1-butanol, 2-butanol, isobutanol, tert-butanol, 1-pentanol, 2-pentanol, 3-pentanol, 2-methyl-1-butanol, 3-methyl-1-butanol, and 2-methyl-2-butanol in the temperature range of 250 K to 330 K were measured by a gas stripping method and partial molar excess enthalpies were calculated from the activity coefficients. A rigorous formula for evaluating the Henry's law constants from the gas stripping measurements was used for the data reduction of these highly volatile mixtures. The uncertainty is about 2% for the Henry's law constants and 3% for the estimated infinite dilution activity coefficients. In the evaluation of the infinite dilution activity coefficients, the nonideality of the solute such as the fugacity coefficient and Poynting correction factor cannot be neglected, especially at higher temperatures. The estimated uncertainty of the infinite dilution activity coefficients includes 1% for nonideality

The cohesive energy of metallic einsteinium determines whether einsteinium is a trivalent or divalent metal. The enthalpy of sublimation, a measure of the cohesive energy, is calculated from the partial pressures of einsteinium over an alloy. The partial pressure of 253 Es has been measured over the range 470--870 K, using combined target and mass spectrometric Knudsen effusion techniques. An alloy was prepared with einsteinium dissolved in a ytterbium solvent to produce a very dilute solution. Partial pressure measurements on the alloy were amenable to the experimental technique and a data analysis using a Henry's law treatment of the data. Vapor pressure data are combined with an estimated crystal entropy S 0 298 and ΔC 0 /sub p/ for ytterbium, to produce enthalpy, entropy, and free energy functions from 298 to 1300 K. The vapor pressure of einsteinium in a dilute einsteinium--ytterbium alloy is described by the equation log P(atm) = -(6815 +- 216)/T+2.576 +- 0.337, from which we calculate for the enthalpy of sublimation of pure einsteinium ΔH 0 298 (second law) = 31.76 kcal/mol. The value of the enthalpy of sublimation is consistent with the conclusion that Es is a divalent metal

Science of consciousness and the hard problem
Energy Technology Data Exchange (ETDEWEB)
Stapp, H.P.
1996-05-22
Quantum theory is essentially a rationally coherent theory of the interaction of mind and matter, and it allows our conscious thoughts to play a causally efficacious and necessary role in brain dynamics. It therefore provides a natural basis, created by scientists, for the science of consciousness. As an illustration it is explained how the interaction of brain and consciousness can speed up brain processing, and thereby enhance the survival prospects of conscious organisms, as compared to similar organisms that lack consciousness. As a second illustration it is explained how, within the quantum framework, the consciously experienced {open_quotes}I{close_quotes} directs the actions of a human being. It is concluded that contemporary science already has an adequate framework for incorporating causally efficacious experimential events into the physical universe in a manner that: (1) puts the neural correlates of consciousness into the theory in a well defined way, (2) explains in principle how the effects of consciousness, per se, can enhance the survival prospects of organisms that possess it, (3) allows this survival effect to feed into phylogenetic development, and (4) explains how the consciously experienced {open_quotes}I{close_quotes} can direct human behaviour.

Fort Collins Science Center-Fiscal year 2009 science accomplishments
Wilson, Juliette T.
2010-01-01
Public land and natural resource managers in the United States are confronted with increasingly complex decisions that have important ramifications for both ecological and human systems. The scientists and technical professionals at the U.S. Geological Survey Fort Collins Science Center?many of whom are at the forefront of their fields?possess a unique blend of ecological, socioeconomic, and technological expertise. Because of this diverse talent, Fort Collins Science Center staff are able to apply a systems approach to investigating complicated ecological problems in a way that helps answer critical management questions. In addition, the Fort Collins Science Center has a long record of working closely with the academic community through cooperative agreements and other collaborations. The Fort Collins Science Center is deeply engaged with other U.S. Geological Survey science centers and partners throughout the Department of the Interior. As a regular practice, we incorporate the expertise of these partners in providing a full complement of ?the right people? to effectively tackle the multifaceted research problems of today's resource-management world. In Fiscal Year 2009, the Fort Collins Science Center's scientific and technical professionals continued research vital to Department of the Interior's science and management needs. Fort Collins Science Center work also supported the science needs of other Federal and State agencies as well as non-government organizations. Specifically, Fort Collins Science Center research and technical assistance focused on client and partner needs and goals in the areas of biological information management and delivery, enterprise information, fisheries and aquatic systems, invasive species, status and trends of biological resources (including human dimensions), terrestrial ecosystems, and wildlife resources. In the process, Fort Collins Science Center science addressed natural-science information needs identified in the U

Safety: Science and technique in social problems
International Nuclear Information System (INIS)
Smit, W.A.
1982-01-01
The author describes in a simple and clearly written Dutch text the relationship between scientific and technical knowledge and the social problems concerning the safety of nuclear energy. He begins with the cooling system of reactors and the safety aspects of the associated pumps. He uses this example to illustrate that the quantative determination of failure risks need not necessarily be relevant for judging the acceptance of the risk but is always relevant as a method of judging the effect of technical improvements on safety values. The author then considers the radiological effects of the operation of a nuclear plant by presenting the doses of radioactivity released if a reactor is operating normally, if there are technical problems and in the case of accidents. The corresponding biological effects on man are also presented and in an appendix the radiological consequences of reactor accidents are considered in some detail. He describes a number of models used in such calculations - for metereological distribution, dosimetry for internal radiation, cancer induction - to illustrate the margins of uncertainty in the predictions. According to the author safety aspects should not just be seen as a purely technical problem, starting with the fact that nuclear energy is desirable and then ensuring that all required safety regulations are met. Safety aspects are a social problem and should be considered by first discussing whether nuclear energy is acceptable, taking into consideration such consequences as the effects of possible accidents and the long term effects of reactor operation.

Undergraduates having their first research experience frequently have little idea of what to expect. Institutions offering summer research experiences attempt to address this issue through programs that introduce students to the process and culture of science. However, didactic approaches frequently bore students who prefer more interactive sessions. We describe a "Pass-the-Problem" case study approach that engages groups of students in useful discussions about the research environment they are entering. The cases presented here include keeping a thorough laboratory notebook, balancing laboratory and personal time demands, anxiety about formal presentations, unexpected federal regulatory inspection, working in a lab with limited funds, being used as a technician rather than a researcher, frustration with failed experiments, effects of promotion and tenure on laboratory atmosphere, the importance of reading the research literature, and questioning a career in science. These cases alert students to different situations they might encounter and stimulate discussion about how to deal with them. © 2015 The International Union of Biochemistry and Molecular Biology.

Where civics meets science: building science for the public good through Civic Science.
Garlick, J A; Levine, P
2017-09-01
Public understanding of science and civic engagement on science issues that impact contemporary life matter more today than ever. From the Planned Parenthood controversy, to the Flint water crisis and the fluoridation debate, societal polarization about science issues has reached dramatic levels that present significant obstacles to public discussion and problem solving. This is happening, in part, because systems built to support science do not often reward open-minded thinking, inclusive dialogue, and moral responsibility regarding science issues. As a result, public faith in science continues to erode. This review explores how the field of Civic Science can impact public work on science issues by building new understanding of the practices, influences, and cultures of science. Civic Science is defined as a discipline that considers science practice and knowledge as resources for civic engagement, democratic action, and political change. This review considers how Civic Science informs the roles that key participants-scientists, public citizens and institutions of higher education-play in our national science dialogue. Civic Science aspires to teach civic capacities, to inform the responsibilities of scientists engaged in public science issues and to inspire an open-minded, inclusive dialogue where all voices are heard and shared commitments are acknowledged. © 2016 John Wiley & Sons A/S.

Is normal science good science?
Directory of Open Access Journals (Sweden)
Adrianna Kępińska
2015-09-01
Full Text Available “Normal science” is a concept introduced by Thomas Kuhn in The Structure of Scientific Revolutions (1962. In Kuhn’s view, normal science means “puzzle solving”, solving problems within the paradigm—framework most successful in solving current major scientific problems—rather than producing major novelties. This paper examines Kuhnian and Popperian accounts of normal science and their criticisms to assess if normal science is good. The advantage of normal science according to Kuhn was “psychological”: subjective satisfaction from successful “puzzle solving”. Popper argues for an “intellectual” science, one that consistently refutes conjectures (hypotheses and offers new ideas rather than focus on personal advantages. His account is criticized as too impersonal and idealistic. Feyerabend’s perspective seems more balanced; he argues for a community that would introduce new ideas, defend old ones, and enable scientists to develop in line with their subjective preferences. The paper concludes that normal science has no one clear-cut set of criteria encompassing its meaning and enabling clear assessment.

From June 1986 to December 1996, 643 patients presenting with acquired immunodeficiency syndrome (AIDS)-related epidemic Kaposi`s sarcoma were treated with irradiation at the Oncology Department of Henri Mondor University Hospital. Three-hundred eighty-seven patients (60 %) had previously received a treatment with interferon (259 patients, 40.2 %), vinblastine (225 patients, 34.5 %), doxorubicin (22 patients, 3.4 %), bleomycin (19 patients, 2.9 %), and/or antiviral treatment (216, 33.5 %). The radiotherapy was delivered by 4 MeV OR 8 MeV electron beam for extended cutaneous fields and 45-100 kV x-ray for localized fields. The delivered dose was 20 Gy in 2 weeks (2.5 Gy/fraction, 4 fractions/week) followed by 2 weeks rest and second series of 10 Gy in 1 week. For oral cavity lesions, we used a series of 15.2 Gy was delivered (1.9 Gy/fraction, 4 fractions/week), followed for three patients by a 3 week rest and by a similar second series of 15.2 Gy.Six-hundred and twenty-one patients were evaluable and the objective response rate was 92 %, with e complete regression of clinical and functional symptoms for all patients. The skin tolerance was good, with 7.3 % grade I reactions, 69.3 % of grade II reactions, and 23.4 % grade III reactions. There was a correlation between recurrence rate and the occurrence of opportunistic infections. This analysis shows the efficacy of dose radiotherapy for treatment of epidemic Kaposi sarcoma.

The Soundscapes of Henry Mayhew Urban Ethnography and Technologies of Transcription
Directory of Open Access Journals (Sweden)
Helen Groth
2012-11-01
Full Text Available Contemporary reviewers of London Labour and the London Poor were quick to label as inauthentic both the engraved re-mediations of John Beard’s daguerreotype portraits and Henry Mayhew’s transcription of the voices of London’s street habitués. Mayhew’s literal mediations of patter, slang and speech rhythms were the subject of particular scrutiny. As one critic acerbically observed: ‘The photographs no doubt are accurate enough, but those dialogues smell of the footlights.’ Such criticisms strike at the core of Mayhew’s commitment to the technologies of faithful mimesis and the mediation of an authentic experience of the everyday lives of London’s wandering tribes. Sound bites of characteristic speech serve as titles for many of the engraved reproductions of John Beard’s daguerreotypes reinforcing the analogy between visual and textual modes of transcription. Likewise Mayhew insists that his various re-enactments of the multi-sensorial experience of elbowing through London’s crowded marketplaces and streets are ‘unvarnished’ transparent mediations of its various sounds and voices. Central to Mayhew’s enterprise is the commitment to recording and capturing a dying way of life. Now silenced voices are captured and remediated to ‘shock’ and teach through the ‘heart’ to use Mayhew’s terminology. This paper will reconsider Mayhew’s investment in the power of sympathetic communication in the context of broader transformations in mid-nineteenth century conceptions of the media as a conduit for information rather than as a mechanism of persuasion.

Full Text Available Problem setting. Social and environmental issues of waste management facing society relatively recently, but showed a tendency to expand and deepen, which in turn caused the necessity of formation of effective policy in this area. Recent research and publications analysis. Some aspects of the present stage of the formation of environmental law and its relationship to nature and resources law, structural and systemic connections was studied by various researchers in the context of environmental policy and legislation analysis, regulation of wildlife relationships, expanding the scope of regulation of resource. In particular, they can mark out V. Andreytsev, A. Getman, M. Krasnova, N. Malisheva and others. However, comprehensive studies of this policy is currently not available. Paper objective. The purpose of the article is a theoretical analysis of the current state of environmental law, the formation of the next stage of development of natural resource relationships, their expansion and transformation into a resource (ecologic and resource in order to adequately respond to the differentiation and complexity of structural and systemic linkages. Paper main body. The development and dynamics of the environmental, natural resources legislation is largely driven by global and European processes and requires constant updating in order to overcome gaps, timely and adequate response to contemporary challenges, changes in value paradigms and so forth. One of these problems is the development of traditional branches of law and directions research that, in turn, raises the question of substantive content, structural and systemic links of these areas of law. Any delay in the establishment of the theoretical and methodological and scientific and legal framework for a new legal phenomena in the framework of ecological and legal science creates the preconditions for the expansion of research not only to them but also in relation to the already well

Philosophy and the front line of science.
Pernu, Tuomas K
2008-03-01
According to one traditional view, empirical science is necessarily preceded by philosophical analysis. Yet the relevance of philosophy is often doubted by those engaged in empirical sciences. I argue that these doubts can be substantiated by two theoretical problems that the traditional conception of philosophy is bound to face. First, there is a strong normative etiology to philosophical problems, theories, and notions that is dfficult to reconcile with descriptive empirical study. Second, conceptual analysis (a role that is typically assigned to philosophy) seems to lose its object of study if it is granted that terms do not have purely conceptual meanings detached from their actual use in empirical sciences. These problems are particularly acute to the current naturalistic philosophy of science. I suggest a more concrete integration of philosophy and the sciences as a possible way of making philosophy of science have more impact.

Genetics problem solving and worldview
Dale, Esther
The research goal was to determine whether worldview relates to traditional and real-world genetics problem solving. Traditionally, scientific literacy emphasized content knowledge alone because it was sufficient to solve traditional problems. The contemporary definition of scientific literacy is, "The knowledge and understanding of scientific concepts and processes required for personal decision-making, participation in civic and cultural affairs and economic productivity" (NRC, 1996). An expanded definition of scientific literacy is needed to solve socioscientific issues (SSI), complex social issues with conceptual, procedural, or technological associations with science. Teaching content knowledge alone assumes that students will find the scientific explanation of a phenomenon to be superior to a non-science explanation. Formal science and everyday ways of thinking about science are two different cultures (Palmer, 1999). Students address this rift with cognitive apartheid, the boxing away of science knowledge from other types of knowledge (Jedege & Aikenhead, 1999). By addressing worldview, cognitive apartheid may decrease and scientific literacy may increase. Introductory biology students at the University of Minnesota during fall semester 2005 completed a written questionnaire-including a genetics content-knowledge test, four genetic dilemmas, the Worldview Assessment Instrument (WAI) and some items about demographics and religiosity. Six students responded to the interview protocol. Based on statistical analysis and interview data, this study concluded the following: (1) Worldview, in the form of metaphysics, relates to solving traditional genetic dilemmas. (2) Worldview, in the form of agency, relates to solving traditional genetics problems. (3) Thus, worldview must be addressed in curriculum, instruction, and assessment.

Graduates with good critical thinking and problem solving (CTPS) skills are likely to boost their employability to live in 21st century. The demands of graduates to be equipped with CTPS skills have shifted our education system in focusing on these elements in all levels of education, from primary, the secondary, and up to the tertiary education, by fostering interesting teaching and learning activities such as fieldwork activity in science classes. Despite the importance of the CTPS skills, little is known about whether students' interests in teaching and learning activities, such as fieldwork activity, have any influence on the students CTPS skills. Therefore, in this investigation, firstly to examine students interests in learning science through fieldwork activity. Secondly, this study examined whether the students' interest in learning science through fieldwork activity have affect on how the students employ CTPS skills. About 100 Diploma of Science students in Universiti Pendidikan Sultan Idris (UPSI) were randomly chosen to participate in this study. All of the participants completed a survey on how they find the fieldwork activity implemented in their science classes and it relevents towards their CTPS skills development. From our findings, majority of the students (91%) find that fieldwork activity is interesting and helpful in increasing their interest in learning science (learning factor) and accommodate their learning process (utility). Results suggest that students' interest on the fieldwork activity in science classes does have some influence on the students development of CTPS skills. The findings could be used as an initial guideline by incorporating students' interest on other teaching and learning activities that being implemented in science classes in order to know the impacts of these learning activities in enhancing their CTPS skills.

Statistical physics of hard optimization problems
International Nuclear Information System (INIS)
Zdeborova, L.
2009-01-01
Optimization is fundamental in many areas of science, from computer science and information theory to engineering and statistical physics, as well as to biology or social sciences. It typically involves a large number of variables and a cost function depending on these variables. Optimization problems in the non-deterministic polynomial (NP)-complete class are particularly difficult, it is believed that the number of operations required to minimize the cost function is in the most difficult cases exponential in the system size. However, even in an NP-complete problem the practically arising instances might, in fact, be easy to solve. The principal question we address in this article is: How to recognize if an NP-complete constraint satisfaction problem is typically hard and what are the main reasons for this? We adopt approaches from the statistical physics of disordered systems, in particular the cavity method developed originally to describe glassy systems. We describe new properties of the space of solutions in two of the most studied constraint satisfaction problems - random satisfy ability and random graph coloring. We suggest a relation between the existence of the so-called frozen variables and the algorithmic hardness of a problem. Based on these insights, we introduce a new class of problems which we named ”locked” constraint satisfaction, where the statistical description is easily solvable, but from the algorithmic point of view they are even more challenging than the canonical satisfy ability.

Ecological science contributes to solving a broad range of environmental problems. However, lack of ecological literacy in practice often limits application of this knowledge. In this paper, we highlight a critical but often overlooked demand on ecological literacy: to enable professionals of various careers to apply scientific knowledge when faced with environmental problems. Current university courses on ecology often fail to persuade students that ecological science provides important tools for environmental problem solving. We propose problem-based learning to improve the understanding of ecological science and its usefulness for real-world environmental issues that professionals in careers as diverse as engineering, public health, architecture, social sciences, or management will address. Courses should set clear learning objectives for cognitive skills they expect students to acquire. Thus, professionals in different fields will be enabled to improve environmental decision-making processes and to participate effectively in multidisciplinary work groups charged with tackling environmental issues.
