  1. Alfred North Whitehead, Process Thought, and the Religious Education of Adults.

    ERIC Educational Resources Information Center

    English, Leona M.

    2000-01-01

    Discusses implications of Whitehead's process thought (the primacy of becoming/process over being/product), especially in terms of relationship building and recovery of mind and heart in teaching. Suggests how a process approach to adult religious education can offer a more inclusive vision of spirituality. (SK)

  2. Whitehead's Multiverse

    NASA Astrophysics Data System (ADS)

    McHenry, Leemon

    2012-09-01

    Alfred North Whitehead advanced a version of multiverse theory in 19291 that bears a remarkable affinity to the revolutionary ideas of current cosmological speculation.2 He postulated his theory for some of the very same reasons as those advanced today by leading cosmologists and physicists such as Martin Rees, Lee Smolin, Stephen Hawking, Max Tegmark and Steven Weinberg, but his theory has largely gone unnoticed. While Whitehead knew nothing of the great advances in big bang theory, expansion, inflation and the unification of physics in post-Hubble cosmology when he wrote Process and Reality in the 1920s, he sought to explain the origin of our universe from its predecessor and to unify the fragmentary theories of physics into a grand theory.

    PubMed

    Fichman, M

    2001-06-01

    Evolutionary theory aroused vigorous debate in the late-19th century, regarding both its scientific status and its sociocultural implications. Alfred Russel Wallace's lecture tour of North America, during 1886-1887, affords a striking insight into his particular interpretation of evolution and reveals the depth of his conviction that science was inseparable from ethical and political realities. Wallace's views on matters scientific and cultural were as controversial and significant in North America as they were in Great Britain and Europe. PMID:11468798

  9. Wheeler and Whitehead: Process Biology and Process Philosophy in the Early Twentieth Century.

    PubMed

    Sölch, Dennis

    2016-07-01

    The case of William Morton Wheeler and Alfred North Whitehead represents a striking example of how biologists and philosophers engaged in a common enterprise in the early twentieth century. Both challenge the notion that the living world is composed of distinct organisms. Based on his studies of the behavior of social insects, Wheeler developed a concept of superorganisms that paved the way for a theory of emergent evolution. This paper argues that Whitehead, whose relation to academic biology has been largely ignored, drew on Wheeler's findings and integrated them into a universal philosophical cosmology. PMID:27477347

  11. A Unscientific Physics: Hegel and Whitehead on the Philosophy of Nature

    NASA Astrophysics Data System (ADS)

    Kite, David Knight

    The thesis of this dissertation is that nature is not merely the province of the natural sciences, and that contemporary philosophy could greatly benefit from a recovery of the Philosophy of Nature. Although philosophy has traditionally developed its own concept of nature, philosophers have recently come to dispute the ability of philosophy to contribute to natural knowledge, and to deny that there is any knowledge of nature beyond that offered by the empirical sciences. This dissertation is an attempt to isolate the particular problems and questions which form a philosophical idea of nature. This study investigates the work of G. W. F. Hegel and Alfred North Whitehead in this field. These two philosophers are especially relevant to this task because they took up these questions during an age after natural science had become separate and distinct from philosophy. The relationship between empirical science and philosophy is therefore a central concern in their work in this area. This investigation concludes that the natural sciences present an abstract and partial account of nature while Philosophy of Nature is largely an attempt to describe the rationality of the individual. Both Hegel and Whitehead feel the central problem of philosophy of nature is to explain how nature itself is the agent of its own rationality, and how notions such as subjectivity, value and rationality are part of all forms and levels of physical existence. The Philosophy of Nature is therefore central to many current fields of philosophical interest, such as the Philosophy of Science and Natural Knowledge, the Philosophy of Mind, Ethics and the Metaphysics of Morals, and offers an important response to the division between the sciences and the humanities. The first three chapters examine Whitehead's and Hegel's critiques of scientific understanding and the limitations of such an approach to nature. The latter three chapters then present the basic features of Hegel's and Whitehead's own work

  13. Whitehead's Philosophy and Quantum Mechanics (QM)

    NASA Astrophysics Data System (ADS)

    Malin, Shimon

    This paper is a tribute to Abner Shimony and a continuation of my discussions with him. In the first part some ofWhitehead's concepts, and, in particular, actual entities and atemporal processes, are introduced. These are shown to correspond to the objectivized aspects of the collapse of quantum states. Next we reconcile the entanglement of quantum states with the speed of light barrier for the transmission of information by modifying Whitehead's system: We suggest that events that take place far apart can be aspects if the same actual entity. We show that this takes care of Lovejoy's objection to Whitehead's system.

    This report gives information on the physical characteristics of Whitehead Watershed and on the characteristics of the suspended sediment transported into and discharged from the reservoirs. Selected periods of significant runoff and outflow from April 1955 to September 1956 are discussed. Particle-size distribution of inflow and outflow samples indicates that all the sand entering reservoir 1 is trapped and that most of the sand entering reservoir 2 is trapped. Results of chemical analyses of water samples and a comparison of suspended-sediment size analyses in native water and in distilled water with dispersing agent indicate that significant sediment flocculation may occur in the reservoirs.

  1. Recurrent hybridization and recent origin obscure phylogenetic relationships within the 'white-headed' gull (Larus sp.) complex.

    Species complexes that have undergone recent radiations are often characterized by extensive allele sharing due to recent ancestry and (or) introgressive hybridization. This can result in discordant evolutionary histories of genes and heterogeneous genomes, making delineating species limits difficult. Here we examine the phylogenetic relationships among a complex group of birds, the white-headed gulls (Aves: Laridae), which offer a unique window into the speciation process due to their recent evolutionary history and propensity to hybridize. Relationships were examined among 17 species (61 populations) using a multilocus approach, including mitochondrial and nuclear intron DNA sequences and microsatellite genotype information. Analyses of microsatellite and intron data resulted in some species-based groupings, although most species were not represented by a single cluster. Considerable allele and haplotype sharing among white-headed gull species was observed; no locus contained a species-specific clade. Despite this, our multilocus approach provided better resolution among some species than previous studies. Interestingly, most clades appear to correspond to geographic locality: our BEAST analysis recovered strong support for a northern European/Icelandic clade, a southern European/Russian clade, and a western North American/canus clade, with weak evidence for a high latitude clade spanning North America and northwestern Europe. This geographical structuring is concordant with behavioral observations of pervasive hybridization in areas of secondary contact. The extent of allele and haplotype sharing indicates that ecological and sexual selection are likely not strong enough to complete reproductive isolation within several species in the white-headed gull complex. This suggests that just a few genes are driving the speciation process. PMID:27369453

    2002-08-01

    At the beginning of the 20th century, Alfred Binet sought teaching positions at the Collége de France and the Sorbonne. Binet wanted to develop experimental psychology in France, but the strong psychopathological orientation of French psychology blocked his ambition. The 1st part of this article relates the history of the introduction of psychology, via Théodule Ribot, to the Sorbonne and the Collège de France. Ribot's premature retirement from the Collège de France in 1901 triggered a battle that led to Binet's repeated failure to gain access to these institutions of highter education and the success in 1902 of Ribot's students: Pierre Janet at the Collège de France and George Dumas at the Sorbonne.

  5. Lead isotopes and lead shot ingestion in the globally threatened marbled teal (Marmaronetta angustirostris) and white-headed duck (Oxyura leucocephala).

    Lead isotope ratios ((206)Pb/(207)Pb and (208)Pb/(207)Pb) and concentrations in the livers and bones of marbled teal and white-headed duck found dead or moribund were determined in order to establish the main lead source in these waterfowl species. Lead concentrations in bone (dry weight) and liver (wet weight) were found to be very high in many of the white-headed ducks (bone: geometric mean=88.9 ppm, maximum=419 ppm; liver: geometric mean=16.8 ppm, maximum=57.0 ppm). Some of the marbled teal had high lead levels in the bones but liver lead levels were all low (bone: geometric mean=6.13 ppm, maximum=112 ppm; liver: geometric mean=0.581 ppm, maximum=4.77 ppm). Ingested lead shot were found in 71% of the white-headed duck and 20% of the marbled teal. The (206)Pb/(207)Pb ratio in livers and bones of white-headed ducks and marbled teals showed no significant differences compared to the ratios obtained from lead shot. The (206)Pb/(207)Pb ratio in bones of marbled teal ducklings with the highest lead concentrations tended to resemble the ratios of lead shot, which supports our hypothesis that the lead was derived from the hens. We also found that the lead ratios of lead shot and lead ratios described for soils in the area overlapped, but also that the isotopic ratio (206)Pb/(207)Pb in lead shot used in Spain has a narrow range compared with those used in North America. The principal source of lead in many of these birds was, however, most likely lead shot, as supported by the similar isotopic ratios, high lead concentrations in tissues and evidence of ingested shot.

    During 2009, while we were celebrating Charles Darwin and his The origin of species, sadly, little was said about the critical contribution of Alfred Russel Wallace (1823-1913) to the development of the theory of evolution. Like Darwin, he was a truly remarkable nineteenth century intellect and polymath and, according to a recent book by Roy Davies (The Darwin conspiracy: origins of a scientific crime), he has a stronger claim to the Theory of Evolution by Natural Selection than has Darwin. Here we present a critical comparison between the contributions of the two scientists. Sometimes referred to as 'The other beetle-hunter' and largely neglected for many decades, Wallace had a far greater experience of collecting and investigating animals and plants from their native habitats than had Darwin. He was furthermore much more than a pioneer biogeographer and evolutionary theorist, and also made contributions to anthropology, ethnography, geology, land reform and social issues. However, being a more modest, self-deprecating man than Darwin, and lacking the latter's establishment connections, Wallace's contribution to the theory of evolution was not given the recognition it deserved and he was undoubtedly shabbily treated at the time. It is time that Wallace's relationship with Darwin is reconsidered in preparation for 2013, the centenary of Wallace's death, and he should be recognized as at least an equal in the Wallace-Darwin theory of evolution.

Although they went their separate ways, three similarities in their research strategies have been found and are discussed. Elements of Whitehead's Hawthorne study and Skinner's concurrent, parallel work reveal that they both (a) introduced the cumulative curve to report data, (b) used a small number of subjects studied over time, and (c) used highly accurate recording devices. A few “afterwords” are offered on their lives and writings, and again, on the Hawthorne effect. A suggestion is made that a Skinner–Whitehead research approach might be useful in studying gambling behavior. PMID:22478490

    We investigated the diet of a group of François' langur inhabiting a forest fragment between August 2002 and July 2003 to add to our knowledge of behavior and ecology of this langur. Our objective was to study whether the François' langur would adopt a feeding strategy similar to the white-headed langur in the same nature reserve. Data indicated that a total of 37 plant species were eaten by François' langur; however, only ten species accounted for 90% of the total feeding time. Four species belong to the ten most dominant tree species within the vegetation quadrats. Ninety-four percent of feeding time of François' langur was spent on leaves, whereas the remaining 6% of time was spent on fruits, flowers and twigs. Results also demonstrated that François' langur are similar to white-headed langur in being predominantly folivorous and that Francois' langur adopted a similar strategy to white-headed langur in diet, dietary variation and time spent on feeding. François' langur exhibited a habitat use preference for the middle zone of the forest, whereas the white-headed langur utilized the bottom zone of the forest. Further analysis indicates that human interference and habitat fragmentation caused by agriculture also impact habitat use.

    It is commonplace to point out that Alfred Kinsey's taxonomic work on gall wasps provided a methodology for his studies of human sexual behavior. It is equally commonplace to point out that, when researching and presenting his sexual studies, Kinsey's professedly neutral scientific data were constrained by a social agenda. What I have done in this paper is to join these two claims and demonstrate, with particular reference to Kinsey's Sexual Behavior in the Human Male, how his zoology helped guide Kinsey to a naturalistic ethics that, despite contrasts to, shared certain parallel logical failures with the traditional ethics of his critics.

    2013-12-01

    Alfred Russel Wallace (1823-1913) is an important figure in the history of science, but there remain many questions about the nature of his world view, and how it developed. Here, Wallace's appreciation of the role of final causes in evolution is linked to some of its probable origins, with an emphasis on the influence of Alexander von Humboldt (1769-1859). The question is then asked whether a final causes-based scientific agenda might be possible, and answered by drawing attention to two current efforts in that direction by Adrian Bejan, and by the author. A sketch of the latter approach, adapted from Spinozian thinking, is given, with an empirical example involving drainage basin morphology that suggests structural influences of a final causes sort.

    Great men are not a common occurrence. Indeed, they are a rare find. Though respected and lauded in their time, it is only in retrospect that their true contributions can be adequately measured as a surgeon, an educator and a scientist. Such is the case of Dr. Alfred Blalock. Many have considered him the father of modern cardiac surgery. All consider his “blue baby” operation to be one of the landmarks of cardiac surgery and, as the chief of surgery at Johns Hopkins, he trained many who would become the leaders of our discipline. His continual reach for excellence helped him to not only affect, but revolutionize the paradigm of surgical research, an understanding of the physiology of shock and the surgical management of pulmonic stenosis/atresia. Dr. Blalock was the 30th president of the American Association for Thoracic Surgery and his presidential address was given in 1951. PMID:22248679

  15. Habitat suitability and nest survival of white-headed woodpeckers in unburned forests of Oregon

    2011-01-01

    We evaluated habitat suitability and nest survival of breeding white-headed woodpeckers (Picoides albolarvatus) in unburned forests of central Oregon, USA. Daily nest-survival rate was positively related to maximum daily temperature during the nest interval and to density of large-diameter trees surrounding the nest tree. We developed a niche-based habitat suitability model (partitioned Mahalanobis distance) for nesting white-headed woodpeckers using remotely sensed data. Along with low elevation, high density of large trees, and low slope, our habitat suitability model suggested that interspersion-juxtaposition of low- and high-canopy cover ponderosa pine (Pinus ponderosa) patches was important for nest-site suitability. Cross-validation suggested the model performed adequately for management planning at a scale >1 ha. Evaluation of mapped habitat suitability index (HSI) suggested that the maximum predictive gain (HSI=0.36), where the number of nest locations are maximized in the smallest proportion of the modeled landscape, provided an objective initial threshold for identification of suitable habitat. However, managers can choose the threshold HSI most appropriate for their purposes (e.g., locating regions of low-moderate suitability that have potential for habitat restoration). Consequently, our habitat suitability model may be useful for managing dry coniferous forests for white-headed woodpeckers in central Oregon; however, model validation is necessary before our model could be applied to other locations. ?? 2011 The Wildlife Society.

  17. Hybridization among Arctic white-headed gulls (Larus spp.) obscures the genetic legacy of the Pleistocene

    We studied the influence of glacial oscillations on the genetic structure of seven species of white-headed gull that breed at high latitudes (Larus argentatus, L. canus, L. glaucescens, L. glaucoides, L. hyperboreus, L. schistisagus, and L. thayeri). We evaluated localities hypothesized as ice-free areas or glacial refugia in other Arctic vertebrates using molecular data from 11 microsatellite loci, mitochondrial DNA (mtDNA) control region, and six nuclear introns for 32 populations across the Holarctic. Moderate levels of genetic structure were observed for microsatellites (FST= 0.129), introns (ΦST= 0.185), and mtDNA control region (ΦST= 0.461), with among-group variation maximized when populations were grouped based on subspecific classification. Two haplotype and at least two allele groups were observed across all loci. However, no haplotype/allele group was composed solely of individuals of a single species, a pattern consistent with recent divergence. Furthermore, northernmost populations were not well differentiated and among-group variation was maximized when L. argentatus and L. hyberboreus populations were grouped by locality rather than species, indicating recent hybridization. Four populations are located in putative Pleistocene glacial refugia and had larger t estimates than the other 28 populations. However, we were unable to substantiate these putative refugia using coalescent theory, as all populations had genetic signatures of stability based on mtDNA. The extent of haplotype and allele sharing among Arctic white-headed gull species is noteworthy. Studies of other Arctic taxa have generally revealed species-specific clusters as well as genetic structure within species, usually correlated with geography. Aspects of white-headed gull behavioral biology, such as colonization ability and propensity to hybridize, as well as their recent evolutionary history, have likely played a large role in the limited genetic structure observed.

    Baylisascaris procyonis is a well-known ascaridoid nematode that causes larva migrans in humans and many other animal species. The North American raccoon (Procyon lotor) is the definitive host, which has been successfully introduced in the past decades to other geographical regions around the world. Two white-headed lemurs (Eulemuralbifrons) from a Zoological Park in Lugo, Spain, developed severe neurological signs within a brief period after being transferred from exhibit and placed in close contact with three captive raccoons from the same zoo. One lemur was euthanized due to the severity of disease progression and histopathology revealed granulomatous inflammation and ascaridoid larvae in kidneys, lung, spleen and brain. Larvae were identified as B. procyonis larvae by real time PCR. In light of the results, the cage mate with similar neurological signs was put on an albendazole treatment regimen adapted from a human pediatric protocol. The aggressive anthelmintic treatment likely contributed to the arrest of clinical signs and recovery of some motor skills. Importantly, Baylisascaris procyonis infection might occur in wild raccoon populations in Spain.

    In this paper, an impulsive state feedback control model for releasing white-headed langurs in captive to the wild is investigated. By using the geometric theory of semi-continuous dynamic system, the method of successor functions and the analogue of the Poincare criterion, it is proved that under certain conditions the system has an order-1 periodic solution with trajectory asymptotical stability, and this periodic solution remains above some critical value. The theoretical results are verified by the numerical simulations. The conclusion is that simultaneously taking the measures of both population migration and artificial breeding can effectively protect wild white-headed langurs, so that the population can continue to survive and can avoid becoming extinct.

    Pilot studies are often used to design short-term research projects and long-term ecological monitoring programs, but data are sometimes discarded when they do not match the eventual survey design. Bayesian hierarchical modeling provides a convenient framework for integrating multiple data sources while explicitly separating sample variation into observation and ecological state processes. Such an approach can better estimate state uncertainty and improve inferences from short-term studies in dynamic systems. We used a dynamic multistate occupancy model to estimate the probabilities of occurrence and nesting for white-headed woodpeckers Picoides albolarvatus in recent harvest units within managed forests of northern California, USA. Our objectives were to examine how occupancy states and state transitions were related to forest management practices, and how the probabilities changed over time. Using Gibbs variable selection, we made inferences using multiple model structures and generated model-averaged estimates. Probabilities of white-headed woodpecker occurrence and nesting were high in 2009 and 2010, and the probability that nesting persisted at a site was positively related to the snag density in harvest units. Prior-year nesting resulted in higher probabilities of subsequent occurrence and nesting. We demonstrate the benefit of forest management practices that increase the density of retained snags in harvest units for providing white-headed woodpecker nesting habitat. While including an additional year of data from our pilot study did not drastically alter management recommendations, it changed the interpretation of the mechanism behind the observed dynamics. Bayesian hierarchical modeling has the potential to maximize the utility of studies based on small sample sizes while fully accounting for measurement error and both estimation and model uncertainty, thereby improving the ability of observational data to inform conservation and management strategies

    Alignment-free approaches are gaining persistent interest in many sequence analysis applications such as phylogenetic inference and metagenomic classification/clustering, especially for large-scale sequence datasets. Besides the widely used k-mer methods, the average common substring (ACS) approach has emerged to be one of the well-known alignment-free approaches. Two recent works further generalize this ACS approach by allowing a bounded number k of mismatches in the common substrings, relying on approximation (linear time) and exact computation, respectively. Albeit having a good worst-case time complexity [Formula: see text], the exact approach is complex and unlikely to be efficient in practice. Herein, we present ALFRED, an alignment-free distance computation method, which solves the generalized common substring search problem via exact computation. Compared to the theoretical approach, our algorithm is easier to implement and more practical to use, while still providing highly competitive theoretical performances with an expected run-time of [Formula: see text]. By applying our program to phylogenetic inference as a case study, we find that our program facilitates to exactly reconstruct the topology of the reference phylogenetic tree for a set of 27 primate mitochondrial genomes, at reasonably acceptable speed. ALFRED is implemented in C++ programming language and the source code is freely available online. PMID:27138275

    Alfred Nobel (1833-1896), mainly known for his invention of dynamite and the creation of the Nobel Prices, was an engineer and inventor active in many fields of science and engineering, e.g. chemistry, medicine, mechanics, metallurgy, optics, armoury and rocketry. Amongst his inventions in rocketry was the smokeless solid propellant ballistite (i.e. cordite) patented for the first time in 1887. As a very wealthy person he actively supported many Swedish inventors in their work. One of them was W.T. Unge, who was devoted to the development of rockets and their applications. Nobel and Unge had several rocket patents together and also jointly worked on various rocket applications. In mid-1896 Nobel applied for patents in England and France for "An Improved Mode of Obtaining Photographic Maps and Earth or Ground Measurements" using a photographic camera carried by a "…balloon, rocket or missile…". During the remaining of 1896 the mechanical design of the camera mechanism was pursued and cameras manufactured. In April 1897 (after the death of Alfred Nobel) the first aerial photos were taken by these cameras. These photos might be the first documented aerial photos taken by a rocket borne camera. Cameras and photos from 1897 have been preserved. Nobel did not only develop the rocket borne camera but also proposed methods on how to use the photographs taken for ground measurements and preparing maps.

    The study was realized among oncological nurses in their daily work routine and aimed to understand these professionals' subjective action, starting from their relation with patients, adopting a phenomenological reference framework based on the ideas of Alfred Schütz. The question: what does working in oncological care mean to you? Please describe, was used to collect statements, which were analyzed and clarified the typical action of a nurse caregiver in this daily routine. The study revealed that oncological care implies dealing with humans in a fragile situation; requires a relationship of affectivity; is care delivery that entails the genesis of professional burnout. Care delivery in oncology is highly complex, requiring a professional competence that goes beyond the technical-scientific sphere. Nursing professionals need to seek strategies which enable them to face the fatigue they are submitted to in their work. PMID:16308624

Initial reactions to Kinsey's research that remain relevant today include "normal" people don't participate in sex surveys, sex surveys are intended to promote homosexuality, and asking people about their sex lives in a nonjudgmental fashion promotes immorality. Episodes of political opposition are documented, and the long-running anti-Kinsey campaign and its impact on the political process are described and discussed. Reasons why people might still oppose sex research are considered, and conclusions are reached about how sex researchers might deal with this problem. PMID:16913278

    Science and technology are intimately related, and advances in science often become possible with the availability of new instrumentation. This has certainly been the case in mass spectrometry, which is used in so many scientific disciplines. Originally developed as an instrument for research in physics it was used in the discovery of isotopes, their recognition as the fundamental species comprising the elements, and the investigation of elemental isotopic composition. Isotope ratio mass spectrometry is a metrological technique of the highest order, and has been widely used in chemical, biochemical, cosmochemical, environmental, geological, physical, and nuclear research. Mass spectrometry presently plays a key role not only in scientific research, but also in industrial operations. This paper highlights the role that Alfred Otto Carl Nier played in bringing mass spectrometry into the mainstream of science. Nier's career spanned a remarkable period in science, and he made crucial contributions to atomic weights, geochronology, isotope geochemistry, nuclear physics, and space science. He is widely viewed as the 'father of modern mass spectrometry', because of his genius with instrumentation, his innovations, and the generosity with which he shared his ideas and designs. It is timely to remember his fundamental work in mass spectrometry, particularly the development of the sector field mass spectrometer, which is still the instrument of choice for many isotope scientists some 66 years after its first appearance in 1940.

    Alfred Russel Wallace (1823-1913) was an influential figure within Russian pre-Synthetic evolutionary biology, i.e. the time period before the Synthetic Theory of Evolution was established (ca. 1880-1930s). His major works were translated into Russian and his general ideas were read and discussed by both insiders and outsiders of scientific evolutionism. At the same time, Wallace played a controversial role in the growth of Darwinism in Russia, and Charles Robert Darwin (1809-1882) has eclipsed Wallace in his influence on Russian evolutionary thinking. In this paper we briefly outline Wallace’s impact on Russian pre-Synthetic scientific evolutionism and its general intellectual climate. We demonstrate that both Russian pro-Darwinian evolutionists and anti-Darwinians (scientific anti-Darwinians as well as creationists) were fully aware of Wallace’s contributions to the development of evolutionary theory. Yet, Wallace’s radical selectionism, as well as his controversial arguments for “design in nature”, predetermined his special place within the Russian intellectual landscape.

  8. Alfred Binet and the Concept of Heterogeneous Orders†

    2012-01-01

    In a comment, hitherto unremarked upon, Alfred Binet, well known for constructing the first intelligence scale, claimed that his scale did not measure intelligence, but only enabled classification with respect to a hierarchy of intellectual qualities. Attempting to understand the reasoning behind this comment leads to an historical excursion, beginning with the ancient mathematician, Euclid and ending with the modern French philosopher, Henri Bergson. As Euclid explained (Heath, 1908), magnitudes constituting a given quantitative attribute are all of the same kind (i.e., homogeneous), but his criterion covered only extensive magnitudes. Duns Scotus (Cross, 1998) included intensive magnitudes by considering differences, which raised the possibility (later considered by Sutherland, 2004) of ordered attributes with heterogeneous differences between degrees (“heterogeneous orders”). Of necessity, such attributes are non-measurable. Subsequently, this became a basis for the “quantity objection” to psychological measurement, as developed first by Tannery (1875a,b) and then by Bergson (1889). It follows that for attributes investigated in science, there are three structural possibilities: (1) classificatory attributes (with heterogeneous differences between categories); (2) heterogeneous orders (with heterogeneous differences between degrees); and (3) quantitative attributes (with thoroughly homogeneous differences between magnitudes). Measurement is possible only with attributes of kind (3) and, as far as we know, psychological attributes are exclusively of kinds (1) or (2). However, contrary to the known facts, psychometricians, for their own special reasons insist that test scores provide measurements. PMID:22912619

It follows that for attributes investigated in science, there are three structural possibilities: (1) classificatory attributes (with heterogeneous differences between categories); (2) heterogeneous orders (with heterogeneous differences between degrees); and (3) quantitative attributes (with thoroughly homogeneous differences between magnitudes). Measurement is possible only with attributes of kind (3) and, as far as we know, psychological attributes are exclusively of kinds (1) or (2). However, contrary to the known facts, psychometricians, for their own special reasons insist that test scores provide measurements.

    Between 1892 and 1904, Alfred Binet (1857-1911) produced, in the psychology laboratory of the Sorbonne, a whole set of original works that still remains little known today. He integrated the laboratory, directed by the psychophysiologist Henry Beaunis (1830-1921), in 1891. We describe the circumstances that led Binet to take the direction of this laboratory in 1895 and present scientific investigations that were conducted there by Binet and his collaborators. For Binet, the laboratory was not narrowly limited to a set of rooms where experiments were conducted by means of sophisticated devices (experimental psychology), it was also a working area, regularly organized, where all the psychological documents were classified, whatever their origin (descriptive psychology). We show that Binet was a pioneer who is still little recognized in various areas of experimental psychology. Binet suffered, at the time, from the indifference of his contemporaries, but he especially regretted not being able to attract students to his laboratory due to the absence of diploma-offering programs.

    Prof. Kohn (1867-1959) was the head of the Institute of Histology at the Medical Faculty of German University in Prague for 26 years. In 2007 we commemorated his 140th birthday, and 2009 we will remember the 50th anniversary of his death. He entered the history of medicine by discovery of nature and origin of parathyroid glands and by pioneer research into chromaffin cells and sympathetic paraganglia. Kohn's papers on the pituitary, interstitial cells of testes, and ovaries are also related to endocrinology. All his studies are based on descriptive and comparative histological and embryological observations. Kohn was twice the dean of German Medical Faculty, and a member or honorary member of many important scientific societies. He was repeatedly nominated for Nobel Prize for physiology and medicine. For his Jewish origin he was expelled from Deutsche Gesellschaft der Wissenschaften und Künste für die Tschechoslowakische Republik in 1939 and transported to Terezin ghetto in 1943. After the war he lived in Prague. On the occasion of his 90th birthday he was elected honorary president of Anatomische Gesellschaft and awarded by the Czechoslovak Order of Labour. Alfred Kohn died in 1959. He was one of the outstanding personalities that Prague gave to the world of science.

    Michell, Joel

    2012-01-01

    In a comment, hitherto unremarked upon, Alfred Binet, well known for constructing the first intelligence scale, claimed that his scale did not measure intelligence, but only enabled classification with respect to a hierarchy of intellectual qualities. Attempting to understand the reasoning behind this comment leads to an historical excursion, beginning with the ancient mathematician, Euclid and ending with the modern French philosopher, Henri Bergson. As Euclid explained (Heath, 1908), magnitudes constituting a given quantitative attribute are all of the same kind (i.e., homogeneous), but his criterion covered only extensive magnitudes. Duns Scotus (Cross, 1998) included intensive magnitudes by considering differences, which raised the possibility (later considered by Sutherland, 2004) of ordered attributes with heterogeneous differences between degrees ("heterogeneous orders"). Of necessity, such attributes are non-measurable. Subsequently, this became a basis for the "quantity objection" to psychological measurement, as developed first by Tannery (1875a,b) and then by Bergson (1889). It follows that for attributes investigated in science, there are three structural possibilities: (1) classificatory attributes (with heterogeneous differences between categories); (2) heterogeneous orders (with heterogeneous differences between degrees); and (3) quantitative attributes (with thoroughly homogeneous differences between magnitudes). Measurement is possible only with attributes of kind (3) and, as far as we know, psychological attributes are exclusively of kinds (1) or (2).

    Alfred Adler (1870-1937) one of the four original members of what was to become the Vienna Psychoanalytic Society, was the first to accept a humanistic-educational model of man in contrast to Freud's medical model of man. This was in line with his deep involvement with prevention; in fact his original interest was in medical prevention. The present paper describes how his work touched on all the points of the contemporary field of psychological prevention. He developed a personality theory most suitable for application in prevention, education and brief psychotherapy. He identified various categories of children at risk. He advocated the right to abortion partly to prevent the birth of a child severely at risk by being unwanted. He considered the then existing dominance of the male sex to be damaging to both sexes. He engaged in practical prevention work by addressing general audiences and especially teachers and by the establishment of and participation in Educational Counseling Centers. He felt that the honest psychologist for reasons of prevention is bound to social advocacy, and that a true psychology of mental health merges into a corresponding world philosophy. These points are fully documented with quotations and references.

    Advances in the biomedical sciences, especially in human genomics, will dramatically influence law, medicine, public health, and many other sectors of our society in the decades ahead. The public already senses the revolutionary nature of genomic knowledge. In the US and Europe, we have seen widespread discussions about genetic discrimination in health insurance; privacy issues raised by the proliferation of DNA data banks; the challenge of interpreting new DNA diagnostic tests; changing definitions of what it means to be healthy; and the science and ethics of cloning animals and human beings. The primary goal of the Whitehead/ASLME Policy Symposium was to provide a bridge between the research community and professionals, who were just beginning to grasp the potential impact of new genetic technologies on their fields. The ''Human Genome Project: Science, Law, and Social Change in the 21st Century'' initially was designed as a forum for 300-500 physicians, lawyers, consumers, ethicists, and scientists to explore the impact of new genetic technologies and prepare for the challenges ahead.

    Nursing care can be considered a social action that is set in the everyday world, where intersubjective relations are established and must be valued by the nurse in the different contexts in which it acts. It is a theoretical study which aimed to highlight the main concepts of the social phenomenology of Alfred Schütz's and its contribution to Nursing as a knowledge and professional practice field. The following questions guided this study: what is the understanding of caring in Nursing from the perspective of the social phenomenology of Alfred Schütz's? How to apply Alfred Schütz's theoretical concepts in the action of caring in Nursing? The theoretical concepts of the social phenomenology and their interface with Nursing were delimited. By incorporating the concepts of the t theory of social action developed by Alfred Schütz into Nursing, this study allows nurses to value and apply the aspects highlighted by this theoretical framework within healthcare, education and scientific research.

    This paper describes the design and the prototyping of a compiling tool for the automated implementation of distributed applications: ALFred. This compiler starts from the formal specification of an application written in ESTEREL, and then integrates end-to-end communication functions tailored to the application characteristics (described in the specification); it finally produces a high performance implementation. The paper describes the communication architecture associated to our automated approach. The compiler is made of two main parts: a control compiler also called ALF compiler; and a data manipulation compiler (the ILP compiler) that combines data manipulation functions in an efficient way (the ILP loop). The ALFred compiler has been designed to allow the development and the analysis of non-layered high performance communication architectures based on ALF and ILP.

    Charles Darwin and Alfred Russel Wallace independently discovered the mechanism of natural selection for evolutionary change. However, they viewed the working of selection differently. For Darwin, selection was always focused on the benefit for the individual. For Wallace, selection was as much something of benefit for the group as for the individual. This difference is traced to their different background political-economic views, with Darwin in favor of Adam Smith's view of society and Wallace following Robert Owen in being a socialist.

    This is a previously unpublished work by Alfred Adler that was written in 1936 as a preface to The Diary of Vaslav Nijinsky. A theory of schizophrenia is described in which characteristic prepsychotic features, especially lack of social interest and oversensitivity to real and imagined slights, lead to increasing irrationalism and preoccupation with grandiose ideas. The establishment of a cooperative therapeutic relationship and the instilling of hope are presented as central factors for successful treatment.

    The quest for a psychological theory to explain the effects of aesthetic surgery reached its high point in the 1920s with the adoption of Alfred Adler's theory of the inferiority complex. The basis for this theory was Adler's early work in the psychological response of the body to disease and "degeneration". Aesthetic surgeons sought out the Adlerian model rather than a Freudian one as purely psychological while its roots, and their own theories, were clearly somatic in origin.

    2012 marked the 100st anniversary of the seminal publications on Continental Drift Theory by Alfred Wegener. These publications (and Wegener's book "On the origin of the continents", published three years later) are widely accepted to be the fundamental breakthrough that opened the path to the Theory of Plate Tectoncis and ultimately the path to modern Geodynamics some 50 years later. In the same historic year of the 1912 publications, Alfred Wegener set off for what was to become the most dramatic of his three Greenland expeditions. On this expedition Wegener and Koch crossed the entire northern icecap of Greenland. In honour of the hundreds anniversary of Wegener's publications, the Austrian Academy of Sciences funded an expedition to trace the footsteps of the 1912 expedition in the spirit of Alfred Wegener, while also conducting modern Earth Science. This expedition that was conducted in summer 2014. For the expedition, a 1952 Cessna180 was acquired in Alaska, adapted with bush wheels, wing extensions and extra tanks and was flown by the author and one of the worlds most renown bush pilots from Alaska in a 10 day effort to Greenland. There, the entire NE Greenland Caledonides were covered and photographed. Field work for a masters projects was conducted and samples were collected from a series of some of the most remote locations in the Caledonides ever visited. Most spectacularly, the original sled of Wegeners 1912 expedition was found some 30 kilometers from its expected location in the Dove Bugt Region of northeastern Greenland.

    Diurnal time-activity budgets of White-headed Ducks were investigated with respect to sex and temporal environmental variables to document behavioral responses to winter conditions and nutritional requirements at Burdur Lake where the largest winter concentrations occur. Behaviors of males and females were recorded separately in randomly selected focal flocks during 1140 sessions. For the entire population a large proportion of time was spent resting. During the day they spent 61% of time resting, 22% feeding, 12% comfort and 5% in locomotion. Resting peaked in the middle of day while feeding was observed frequently in evening and morning. Time use did not differ significantly between sexes. However, it was detected that more time was spent feeding during windy days as wave-height increased.

    The development of organic and physical chemistry as specialist fields, during the middle and end of the 19th century respectively, left inorganic behind as a decidedly less highly regarded subfield of chemistry. Despite Alfred Werner's groundbreaking studies of coordination chemistry in the early 20th century, that inferior status remained in place - particularly in the US - until the 1950s, when the beginnings of a resurgence that eventually restored its parity with the other subfields can be clearly observed. This paper explores the extent to which Werner's heritage - both direct, in the form of academic descendants, and indirect - contributed to those advances. PMID:24983802

    2015-01-01

    Conventional wisdom has had it that the naturalist Alfred Russel Wallace and his colleague Henry Walter Bates journeyed to the Amazon in 1848 with two intentions in mind: to collect natural history specimens, and to consider evidential materials that might reveal the causal basis of organic evolution. This understanding has been questioned recently by the historian John van Wyhe, who points out that with regard to the second matter, at least, there appears to be no evidence of a "smoking gun" variety proving it so. In the present essay the circumstances of Wallace's interest in the matter are reviewed, and van Wyhe is taken to task with alternate explanations for the facts he introduces in his argument. The conclusion is that Wallace almost certainly did have the second objective in mind when he left for both the Amazon, and the Far East.

    The co-discoverer of natural selection, Alfred Russel Wallace, found himself deeply embroiled in a range of controversies surrounding the relationship between science and spiritualism. At the heart of these controversies lay a crisis of evidence in cases of delusion or imposture. He had the chance to observe the many epistemic impasses brought about by this crisis while participating in the trial of the American medium Henry Slade, and through his exchanges with the physiologist William Benjamin Carpenter and the psychical researcher Frederic Myers. These contexts help to explain the increasing value that Wallace placed on the evidence of spirit photography. He hoped that it could simultaneously break these impasses, while answering once and for all the interconnected questions of the unity of the psyche and the reliability of human observation.

    2015-01-01

    Alfred Russel Wallace (1823-1913), naturalist and explorer of South America and the Malay Archipelago, secured his place in history by independently discovering the theory of natural selection. His letter outlining the theory was sent from Ternate in eastern Indonesia and received at Down House, according to Charles Darwin (1809-82), on June 18, 1858, prompting the now-famed evolutionist to rush his languishing manuscript to press. Wallace's contributions to evolutionary biology, biogeography, and anthropology are well known, but his medical views have received far less attention. Within the context of a strident populist antivaccination movement and an ominous elitist eugenics campaign, Wallace took his stand, which revealed itself in a libertarianism that defended traditional socialist constituencies (the working poor, the lumpenproletariat, and feminist reformers) against state-mandated medical interventions. Rather than viewing Wallace as a heterodox contrarian, this article argues that his positions were logical outgrowths of his medical libertarianism and evolutionary and social theories.

    Conventional wisdom has had it that the naturalist Alfred Russel Wallace and his colleague Henry Walter Bates journeyed to the Amazon in 1848 with two intentions in mind: to collect natural history specimens, and to consider evidential materials that might reveal the causal basis of organic evolution. This understanding has been questioned recently by the historian John van Wyhe, who points out that with regard to the second matter, at least, there appears to be no evidence of a "smoking gun" variety proving it so. In the present essay the circumstances of Wallace's interest in the matter are reviewed, and van Wyhe is taken to task with alternate explanations for the facts he introduces in his argument. The conclusion is that Wallace almost certainly did have the second objective in mind when he left for both the Amazon, and the Far East. PMID:25424743

    The co-discoverer of natural selection, Alfred Russel Wallace, found himself deeply embroiled in a range of controversies surrounding the relationship between science and spiritualism. At the heart of these controversies lay a crisis of evidence in cases of delusion or imposture. He had the chance to observe the many epistemic impasses brought about by this crisis while participating in the trial of the American medium Henry Slade, and through his exchanges with the physiologist William Benjamin Carpenter and the psychical researcher Frederic Myers. These contexts help to explain the increasing value that Wallace placed on the evidence of spirit photography. He hoped that it could simultaneously break these impasses, while answering once and for all the interconnected questions of the unity of the psyche and the reliability of human observation.

    Alfred Russel Wallace (1823-1913), naturalist and explorer of South America and the Malay Archipelago, secured his place in history by independently discovering the theory of natural selection. His letter outlining the theory was sent from Ternate in eastern Indonesia and received at Down House, according to Charles Darwin (1809-82), on June 18, 1858, prompting the now-famed evolutionist to rush his languishing manuscript to press. Wallace's contributions to evolutionary biology, biogeography, and anthropology are well known, but his medical views have received far less attention. Within the context of a strident populist antivaccination movement and an ominous elitist eugenics campaign, Wallace took his stand, which revealed itself in a libertarianism that defended traditional socialist constituencies (the working poor, the lumpenproletariat, and feminist reformers) against state-mandated medical interventions.

    Two recent archival items offer material for analysis of Alfred Binet's (1857-1911) and Cyril Burt's (1883-1971) relationship in the early twentieth century. Burt's letter to Binet's biographer Theta Wolf was an answer to her request for information about his contact with Binet. An analysis of Burt's account prompts more questions than it answers. His statements in the letter are compared with previous ones and are put into the context of the activities of the two men, but these do not enlighten us about his actual relations with Binet. The problem arises because of Burt's desciptive vagueness and lack of supporting evidence. Despite attacks against Burt's integrity made from 1976 onward, we found no conclusive evidence of false claims. The negative outcome of this analysis probably results from Burt's faulty memory, and herein lies the caveat that personal memories make unreliable material for historical accounts.

    The recent, unfortunate death of Alfred G. ("Al") Gilman, M.D., Ph.D., represents a sad signpost for an era spanning over 40 years in molecular pharmacology. Gilman's discoveries, influence, and persona were dominant forces in research and training in pharmacology. Here, we review the progression of ideas and knowledge that spawned early work by Gilman and collaborators (among them, one of the authors) and later efforts (including those of the other author) that have recently yielded a comprehensive and precise structural understanding of fundamental topics in pharmacology: the binding of ligands to G protein-coupled receptors (GPCRs) and the interaction of GPCRs with heterotrimeric G proteins and effector molecules. Those data provide new and important insights into the molecular basis that underlies affinity and efficacy, two of the most important features of drug action, which represent the latest chapter in the saga that Al Gilman's work helped launch.

    This article is dedicated to Alfred Sindik (1890-1976), the first Croat specialised in epidemiology. As a student he volunteered at the Institute of Hygiene in Zagreb in its early days. He took his degree from the University of Zagreb School of Medicine in 1929. For many years, he worked at the Institute of Epidemiology, of which ten as its director, having succeeded Dr Černozubov on this position. On 23 July 1949, he received his specialisation degree in epidemiology to become our first epidemiologist. On 14 December 1957, he was promoted to chief physician. Most of his time he spent working in the field, suppressing epidemic outbreaks, and sharing his experiences through scientific publications and teaching, especially at the School for Medical Assistants since its establishment in 1930. He has written a number textbooks for students. Here we list his most important articles and textbooks. PMID:27639044

    Present management of shock derives, in part, from the classic investigations of Walter B. Cannon and Alfred Blalock. The intersections of their professional lives as recorded in the professional literature and in personal correspondence suggest that Blalock's pivotal studies of experimental shock were fueled, at least in part, by Cannon's inability to resolve the inconsistencies of the then-popular toxic theory of shock. Cannon appears to have substantially shaped Blalock's thought and work, initially as authority and competitor and later as colleague and friend. Blalock's experimental proof that injury precipitated obligatory locoregional fluid losses, the effects of which could be ameliorated by vigorous restoration of plasma volume, became a cornerstone of shock theory and therapy.

    In his preface to The Diary of Vaslav Nijinsky, Alfred Adler (1) found his theory of the dynamics of schizophrenia supported in the Diary, (2) alluded to Nijinsky's prepsychotic personality, and (3) briefly touched on the possibility and conditions of recovery. To add to the understanding of Adler's "Preface," this discussion (1) expands his theory of schizophrenia, (2) gives some concrete data of Nijinsky's prepsychotic personality, (3) describes two episodes of recovery subsequent to the "Preface," and (4) introduces an important aspect of Adler's theory, which he had to omit out of consideration for Nijinsky's wife, Romola-namely, her role in her husband's disorder. With the larger theoretical and historical context established. Adler's "Preface" can be appreciated for its predictive validity.

    Alfred François Donné is widely known in the scientific community as the discoverer of Trichomonas vaginalis, since he was the first to illustrate the parasite that later was recognized to cause vaginal infections. However, his other, less-known findings are equally important: he was also the inventor of the photoelectric microscope, with the assistance of his student Léon Foucault, as well as the first to apply photography to microscopic preparations (Daguerreotype). His research in microscopy extended to almost all human fluids that could be investigated and culminated in his famous Atlas, which was illustrated with numerous photographs. Donné was also the first to describe the microscopic appearances of leukaemia based on blood preparations acquired from patients. Finally, his work in the hygiene of child upbringing and nutrition is very significant.

    The search for a modern, humane method of criminal execution was triggered by a freak accident which occurred in Buffalo, New York in 1881. Dr. Alfred P. Southwick (a former steam-boat engineer, noted dentist and dental educator) happened to witness an intoxicated man die after he inadvertently touched a live generator terminal. Southwick's initial reaction was shock. Later, as he pondered this tragic event, he concluded that electrocution was, at least, a quick and seemingly painless way to depart from this earth. As his thoughts turned to common methods of capital punishment, Alfred concluded that death by electrocution could become a more humane alternative, as compared with the more grisly methods (e.g., hanging, beheading by guillotine, garroting, suffocation and flaying). Working through the governor of New York and the state legislature, Southwick originated and successfully promoted the passage of laws which mandated electrical executions in New York and in approximately 20 other states. During 1888-1889, Southwick served on the state's three-person Electrical Death Commission, a group who reported that electrical execution was superior to all other methods. On January 1, 1889, the world's first electrical execution law went into effect. On August 6, 1890, William Francis Kemmler, who had murdered his mistress, was the first person to die in the electric chair. However, this public event became an amateurish spectacle: the initial surge of current did not cause Kemmler's immediate death and a second jolt was needed. Those who witnessed this bungled execution were stunned. Graphic and detailed criticism from both the press and the general public ran high. However, Dr. Southwick vigorously continued to support and finally achieve his goal--to humanize capital punishment through the legal use of electrical execution. PMID:11806253

    It is well known that the contribution of Alfred Russell Wallace (1823-1913) to the development of the "Darwinian" principle of natural selection has often been neglected. Here we focus on how the three anniversaries to celebrate the origin of the Darwin-Wallace theory in Germany in 1909, in 1959 in the divided country, as well as in 2009, have represented Charles Robert Darwin's and Alfred Russell Wallace's contributions. We have analyzed books and proceedings volumes related to these anniversaries, and the main result is that Wallace was almost always ignored, or only mentioned in passing. In 1909, Ernst Haeckel gave a talk in Jena, later published under the title The worldview of Darwin and Lamarck (Das Weltbild von Darwin und Lamarck), but not as the Darwin-Wallace concept. Haeckel mentions Wallace only once. In two important proceedings volumes from the 1959 anniversaries, Wallace was ignored. The only fair treatment of Wallace is given in another book, a collection of documents edited by Gerhard Heberer, for which the author selected nine key documents and reprinted excerpts (1959). Three of them were articles by Wallace, including the Sarawak- and Ternate-papers of 1855 and 1858, respectively. An analysis of the dominant themes during the celebrations of 2009 shows that none of the six topics had much to do with Wallace and his work. Thus, the tendency to exclude Alfred Russell Wallace is an international phenomenon, and largely attributable to the "Darwin industry". PMID:23975642

    Over many years of his life, the British naturalist Alfred Russel Wallace (1823-1913) explored the tropical forests of Malaysia, collecting numerous specimens, including hundreds of birds, many of them new to science. Subsequently, Wallace published a series of papers on systematic ornithology, and discovered a new species on top of a volcano on Ternate, where he wrote, in 1858, his famous essay on natural selection. Based on this hands-on experience, and an analysis of an Archaeopteryx fossil, Wallace suggested that birds may have descended from dinosaurian ancestors. Here, we describe the "dinosaur-bird hypothesis" that originated with the work of Thomas H. Huxley (1825-1895). We present the strong evidence linking theropod dinosaurs to birds, and briefly outline the long and ongoing controversy around this concept. Dinosaurs preserving plumage, nesting sites and trace fossils provide overwhelming evidence for the dinosaurian origin of birds. Based on these recent findings of paleontological research, we conclude that extant birds indeed descended, with some modifications, from small, Mesozoic theropod dinosaurs. In the light of Wallace's view of bird origins, we critically evaluate recent opposing views to this idea, including Ernst Mayr's (1904-2005) arguments against the "dinosaur-bird hypothesis", and document that this famous ornithologist was not correct in his assessment of this important aspect of vertebrate evolution.

    In his pioneering cytoarchitectonic studies of the human brain, Alfred Walter Campbell identified two structurally different areas in the occipital lobes and assigned two different kinds of visual functions to them. The first area, the visuosensory, was essentially on the mesial surface of the calcarine fissure. It was the terminus of nervous impulses generated in the retina and was where simple visual sensations arose. The second area, the visuopsychic, which surrounded or invested the first, was where sensations were interpreted and elaborated into visual perceptions. I argue that Campbell's distinction between the two areas was the starting point for the eventual differentiation of areas V1-V5. After a brief outline of Campbell's early life and education in Australia and of his Scottish medical education and early work as a pathologist at the Lancashire County Lunatic Asylum at Rainhill near Liverpool, I summarise his work on the human brain. In describing the structures he identified in the occipital lobes, I analyse the similarities and differences between them and the related structures identified by Joseph Shaw Bolton. I conclude by proposing some reasons for how that work came to be overshadowed by the later studies of Brodmann and for the more general lack of recognition given Campbell and his work. Those reasons include the effect of the controversies precipitated by Campbell's alliance with Charles Sherrington over the functions of the sensory and motor cortices.

    One hundred and fifty years after Alfred Wallace studied the geographical variation and species diversity of butterflies in the Indomalayan-Australasian Archipelago, the processes responsible for their biogeographical pattern remain equivocal. We analysed the macroevolutionary mechanisms accounting for the temporal and geographical diversification of the charismatic birdwing butterflies (Papilionidae), a major focus of Wallace's pioneering work. Bayesian phylogenetics and dating analyses of the birdwings were conducted using mitochondrial and nuclear genes. The combination of maximum likelihood analyses to estimate biogeographical history and diversification rates reveals that diversity-dependence processes drove the radiation of birdwings, and that speciation was often associated with founder-events colonizing new islands, especially in Wallacea. Palaeo-environment diversification models also suggest that high extinction rates occurred during periods of elevated sea level and global warming. We demonstrated a pattern of spatio-temporal habitat dynamics that continuously created or erased habitats suitable for birdwing biodiversity. Since birdwings were extinction-prone during the Miocene (warmer temperatures and elevated sea levels), the cooling period after the mid-Miocene climatic optimum fostered birdwing diversification due to the release of extinction. This also suggests that current global changes may represent a serious conservation threat to this flagship group.

    The Galápagos Islands (Ecuador) are usually associated with the explorations and theoretical deductions of Charles Robert Darwin (1809-1882), but Alfred Russel Wallace (1823-1913) also investigated these islands and published several reports on the living world of this unique archipelago. In contrast to Darwin, Wallace described the destruction of natural ecosystems by humans and foresaw the resulting extinction of species. Here, we outline two case studies pertinent to Wallace's prediction. First, we summarize the behavior of the predator-naive marine iguanas (Amblyrhynchus cristatus) on the Galápagos Islands, which are threatened by feral dogs and cats imported by humans. We also describe the unique life cycle of the spiny-tailed iguana (Ctenosaura bakeri) from the island of Utila (Honduras), a rare species whose populations are declining because of habitat destructions. In contrast to these threatened, endemic island species, the Green iguana (Iguana iguana) is still widely distributed, although, as a result of de-forestation, in some areas of South America local populations have disappeared. We conclude that Wallace was correct in his prediction that, because of human activities, numerous species of animals and plants will be driven to extinction, notably on islands. PMID:23975644

    2008-01-01

    Alfred Binet (1857-1911) is considered the most representative exponent of the second generation of French experimental psychologists. His scientific work was inspired both by the experimentalism that Théodule Ribot and Hippolyte Taine introduced in France at the end of the 1870s, and by that of Wundt. Drawing from numerous sources, Binet was able to elaborate a psychology that focused on experiments and a controlled observation of pathological phenomena, with the objective of differentiating them from normal phenomena. His scientific production was moreover characterized by the emphasis placed upon the experimental study of "superior" psychic phenomena and, in particular, on their measurement. The aim of this paper is to describe the stages and sources of the "psychological" study of intelligence, which constituted precisely the fil rouge that had indispensably to be followed in order to fully understand the originality of all of Binet's research, whose most mature product was undoubtedly represented by the development of the Echelle métrique de l'intelligence, the first intelligence test in the history of psychology.

    Alfred Binet is internationally recognized as the "father" of the first intelligence test as well as the most faithful French representative of laboratory experimentalism. A historical analysis of his work is therefore necessary to get to a thorough comprehension of 20th century psychology. The present article, starting from Binet's intellectual path and from the suggestions of the previous historical literature, aims at providing fresh insights into Binet's work by trying to capture the intersections between Binet, his naturalistic culture and the political context in which he worked in the early 20th century, when he actively tried to apply experimental psychology to the pedagogical area. In fact, it is possible to underline, with reference to those years, an evident turn towards applications in Binet's psychological production. The article reconstructs the political and institutional background of Binet's research and shows how the naturalism and experimentalism he promoted were complementary to the solidarist conceptions that were particularly prevalent among those who supported his work during the Third Republic.

    In order to achieve the full potential of information technology in healthcare, information systems must have the ability to share and exchange data, which requires the support of standardised medical terminology, such as Systematised Nomenclature of Medicine--Clinical Terms (SNOMED-CT). The Royal Prince Alfred Intensive Care Service and the School of Information Technologies, University of Sydney have been collaborating for over two years, developing pioneering software initiatives for clinical information systems (CIS). More recently, the collaboration resulted in the development of two prototype systems. The Ward Round Information System (WRIS) has been designed to convert clinicians' clinical notes into the formal medical encoding ontology SNOMED-CT, thus enabling more consistent descriptions of patient conditions and allowing large-scale retrieval and analysis from the narrative part of the patient record. In addition, a Clinical Data Analytics Language (CDAL) system has also been developed and is designed to answer questions of the data stored in the CIS. It will assist clinicians in the management of vast amounts of complex information generated during an ICU admission and ultimately improve the quality and efficiency of care. CDAL provides clinicians with the ability to frame any question about their data in their database and get the answer almost immediately. Both systems went live in October 2007, and this report summarises the background, purpose, and progress thus far.

    Sex researcher Alfred Kinsey's vision of sexual taxonomy continued to evolve after he published his first landmark volume on human sexuality, and his research into sexual subcultures went beyond his initial studies of homosexuality and prostitution. In the late 1940s and early 1950s, he developed a new interest in cross-dressing and cross-gender identification. This article outlines how and why he began to interview transvestites and transsexuals, and places his emerging vision of gendered behavior and gender identity within the scientific theories of his day. Kinsey rejected the prevailing views, preferring instead a behaviorist model of gender. He saw cross-dressing and crossgender identification as male phenomena and used them to speculate about sex differences in the capacity for psychological conditioning. In his usual style, he did not condemn transvestites or transsexuals, but he disapproved of the genital surgery requested by male-to-female transsexuals. It was here that Kinsey hit the limits of his well-known sexual liberalism in which he approved of all sexual variations that did not involve coercion. PMID:11420452

    The Galápagos Islands (Ecuador) are usually associated with the explorations and theoretical deductions of Charles Robert Darwin (1809-1882), but Alfred Russel Wallace (1823-1913) also investigated these islands and published several reports on the living world of this unique archipelago. In contrast to Darwin, Wallace described the destruction of natural ecosystems by humans and foresaw the resulting extinction of species. Here, we outline two case studies pertinent to Wallace's prediction. First, we summarize the behavior of the predator-naive marine iguanas (Amblyrhynchus cristatus) on the Galápagos Islands, which are threatened by feral dogs and cats imported by humans. We also describe the unique life cycle of the spiny-tailed iguana (Ctenosaura bakeri) from the island of Utila (Honduras), a rare species whose populations are declining because of habitat destructions. In contrast to these threatened, endemic island species, the Green iguana (Iguana iguana) is still widely distributed, although, as a result of de-forestation, in some areas of South America local populations have disappeared. We conclude that Wallace was correct in his prediction that, because of human activities, numerous species of animals and plants will be driven to extinction, notably on islands.

    One hundred and fifty years after Alfred Wallace studied the geographical variation and species diversity of butterflies in the Indomalayan-Australasian Archipelago, the processes responsible for their biogeographical pattern remain equivocal. We analysed the macroevolutionary mechanisms accounting for the temporal and geographical diversification of the charismatic birdwing butterflies (Papilionidae), a major focus of Wallace’s pioneering work. Bayesian phylogenetics and dating analyses of the birdwings were conducted using mitochondrial and nuclear genes. The combination of maximum likelihood analyses to estimate biogeographical history and diversification rates reveals that diversity-dependence processes drove the radiation of birdwings, and that speciation was often associated with founder-events colonizing new islands, especially in Wallacea. Palaeo-environment diversification models also suggest that high extinction rates occurred during periods of elevated sea level and global warming. We demonstrated a pattern of spatio-temporal habitat dynamics that continuously created or erased habitats suitable for birdwing biodiversity. Since birdwings were extinction-prone during the Miocene (warmer temperatures and elevated sea levels), the cooling period after the mid-Miocene climatic optimum fostered birdwing diversification due to the release of extinction. This also suggests that current global changes may represent a serious conservation threat to this flagship group. PMID:26133078

    This paper examines Karl Alfred von Zittel’s practice in order to uncover the roots of so-called idiographic paleontology.The great American paleontologist Stephen Jay Gould (1941–2002) defined the discipline of idiographic paleontology as illustration and description of the morphological features of extinct species. However, this approach does not investigate macroevolutionary patterns and processes. On the contrary, the paleobiological revolution of the 1970s implemented an epistemic methodology that illustrates macrovelutionary patterns and laws by combining idiographic data with a nomothetic form of explanation. This article elucidates the features of the idiographic data as well as the acquired knowledge coupled with this approach. First of all, Heinrich G. Bronn’s (1800–1862) statistical method is analyzed. Zittel’s practice arose as a reaction against the approximate conclusions reached by Bronn’s quantitative approach. Second, the details of Zittel’s methodology are described in order to bring out its peculiarities.The microscope played a pivotal role in creating and forming Zittel’s morphological data. This analysis sheds new light on the reasons behind the so-called ideographic paleontology, thus revising Gould’s historical reconstruction, as well as on the notion of paleontological data. However, even though Zittel aimed at reaching precise and stable conclusions,his data cannot be used for elucidating evolutionary mechanisms: they are scientific in a purely descriptive sense, but completely useless for biological investigations. Finally, this paper examines how Zittel’s methodology affects the contemporary paleobiological enterprise and thereby reflects upon the notion of natural history.

    Two PhD theses (Alexander Gordienko, 1912; Johannes Angerstein, 1914) and a dissertation in partial fulfillment of a PhD thesis (H. S. French, Zurich, 1914) are reviewed that deal with hitherto unpublished UV-vis spectroscopy work of coordination compounds in the group of Alfred Werner. The method of measurement of UV-vis spectra at Alfred Werner's time is described in detail. Examples of spectra of complexes are given, which were partly interpreted in terms of structure (cis ↔ trans configuration, counting number of bands for structural relationships, and shift of general spectral features by consecutive replacement of ligands). A more complete interpretation of spectra was hampered at Alfred Werner's time by the lack of a light absorption theory and a correct theory of electron excitation, and the lack of a ligand field theory for coordination compounds. The experimentally difficult data acquisitions and the difficult spectral interpretations might have been reasons why this method did not experience a breakthrough in Alfred Werner's group to play a more prominent role as an important analytical method. Nevertheless the application of UV-vis spectroscopy on coordination compounds was unique and novel, and witnesses Alfred Werner's great aptitude and keenness to always try and go beyond conventional practice.

    The first electric projecting microscope and the first published photomicrographs harnessed recent technological developments to provide improved methods of medical illustration for educational purposes. Both projects were the work of two Frenchmen. The impetus came from the microscopist Dr Alfred Donné (1801-78), discoverer of trichomonas vaginalis and leukaemia. Implementation was primarily by his medical-student assistant, Léon Foucault (1819-68), who later gained fame as a physicist, especially with his pendulum demonstration of the Earth's rotation.

    Using a 0-6 scale, Alfred Kinsey demonstrated that the complexity of human sexuality could best be represented on a continuum rather than as a binary. Kinsey developed the scale from models created by his predecessors in human sex research. A primary intention of the scale was to eradicate sexual identity categories altogether in order to eliminate sexual identity-based persecutions and to promote equal rights. As proponents and opponents of homosexual rights both depended on constructions of sexual identity to advance their agendas, Kinsey's ideal was never realized. The scale nonetheless continues to challenge postmodern associations of identity and sexuality. PMID:20924926

    The White-headed Vulture Trigonoceps occipitalis (WhV) is uncommon and largely restricted to protected areas across its range in sub-Saharan Africa. We used the World Database on Protected Areas to identify protected areas (PAs) likely to contain White-headed Vultures. Vulture occurrence on road transects in Southern, East, and West Africa was adjusted to nests per km(2) using data from areas with known numbers of nests and corresponding road transect data. Nest density was used to calculate the number of WhV nests within identified PAs and from there extrapolated to estimate the global population. Across a fragmented range, 400 PAs are estimated to contain 1893 WhV nests. Eastern Africa is estimated to contain 721 nests, Central Africa 548 nests, Southern Africa 468 nests, and West Africa 156 nests. Including immature and nonbreeding birds, and accounting for data deficient PAs, the estimated global population is 5475 - 5493 birds. The identified distribution highlights are alarming: over 78% (n = 313) of identified PAs contain fewer than five nests. A further 17% (n = 68) of PAs contain 5 - 20 nests and 4% (n = 14) of identified PAs are estimated to contain >20 nests. Just 1% (n = 5) of PAs are estimated to contain >40 nests; none is located in West Africa. Whilst ranging behavior of WhVs is currently unknown, 35% of PAs large enough to hold >20 nests are isolated by more than 100 km from other PAs. Spatially discrete and unpredictable mortality events such as poisoning pose major threats to small localized vulture populations and will accelerate ongoing local extinctions. Apart from reducing the threat of poisoning events, conservation actions promoting linkages between protected areas should be pursued. Identifying potential areas for assisted re-establishment via translocation offers the potential to expand the range of this species and alleviate risk.

    To date, historians of psychology have largely ignored the role of academic publishing and the editorial policies of the late nineteenth century. This paper analyzes the role played by academic publishing in the history of psychology in the specific case of France, a country that provides a very interesting and unique model. Up until the middle of the 1890s, there was no collection specifically dedicated to psychology. Alfred Binet was the first to found, in 1897, a collection of works specifically dedicated to scientific psychology. He chose to work with Reinwald-Schleicher. However, Binet was soon confronted with (1) competition from other French publishing houses, and (2) Schleicher's management and editorial problems that were to sound the death knell for Binet's emerging editorial ambitions. The intention of this paper is to encourage the efforts of the pioneers of modern psychology to have their work published and disseminated.

    Tackling the mimetic logic of sex-gender that limits the transsexual subject's sexuality into seeming a poor representation, the author argues that trans pornography and autoethnographic accounts from trans scholars emphasize the affective dimension of trans sex, a material remainder absent from mimetic theories of sexuality. Developing concepts from Alfred North Whitehead's process philosophy, in tandem with Morty Diamond's film Trans Entities: The Nasty Love of Papí and Wil (2007) and a selection of trans theorists, this article elaborates on the horizon of affective potential opened by transgender, brown, kinky, and pornographic "nastiness." The event of "nasty love" solicits a differential becoming, growing the edge of self. PMID:24294885

    Alfred Russel Wallace (1823-1913) and Charles Darwin (1809-1882) are honored as the founders of modern evolutionary biology. Accordingly, much attention has focused on their relationship, from their independent development of the principle of natural selection to the receipt by Darwin of Wallace's essay from Ternate in the spring of 1858, and the subsequent reading of the Wallace and Darwin papers at the Linnean Society on 1 July 1858. In the events of 1858 Wallace and Darwin are typically seen as central players, with Darwin's friends Charles Lyell (1797-1875) and Joseph Dalton Hooker (1817-1911) playing supporting roles. This narrative has resulted in an under-appreciation of a more central role for Charles Lyell as both Wallace's inspiration and foil. The extensive anti-transmutation arguments in Lyell's landmark Principles of Geology were taken as the definitive statement on the subject. Wallace, in his quest to solve the mystery of species origins, engaged with Lyell's arguments in his private field notebooks in a way that is concordant with his engagement with Lyell in the 1855 and 1858 papers. I show that Lyell was the object of Wallace's Sarawak Law and Ternate papers through a consideration of the circumstances that led Wallace to send his Ternate paper to Darwin, together with an analysis of the material that Wallace drew upon from the Principles. In this view Darwin was, ironically, intended for a supporting role in mediating Wallace's attempted dialog with Lyell. PMID:24014172

    The British naturalist Alfred Russel Wallace (1823-1913), who had to leave school aged 14 and never attended university, did extensive fieldwork, first in the Amazon River basin (1848-1852) and then in Southeast Asia (1854-1862). Based on this experience, and after reading the corresponding scientific literature, Wallace postulated that species were not created, but are modified descendants of pre-existing varieties (Sarawak Law paper, 1855). Evolution is brought about by a struggle for existence via natural selection, which results in the adaptation of those individuals in variable populations who survive and reproduce (Ternate essay, 1858). In his monograph Darwinism (1889), and in subsequent publications, Wallace extended the contents of Darwin's Origin of Species (1859) into the Neo-Darwinian theory of biological evolution, with reference to the work of August Weismann (1834-1914). Wallace also became the (co)-founder of biogeography, biodiversity research, astrobiology and evolutionary anthropology. Moreover, he envisioned what was later called the anthropocene (i.e., the age of human environmental destructiveness). However, since Wallace believed in atheistic spiritualism and mixed up scientific facts and supernatural speculations in some of his writings, he remains a controversial figure in the history of biology.

    The importance of instrument firms in the development of psychology, and science in general, should not be underestimated since it would not have been possible for various leading psychologists at the turn of the twentieth century to conduct certain experiments without the assistance of instrument makers, as is often the case today. To illustrate the historical perspective introduced here, the example of Alfred Binet is taken, as he is an interesting case of a psychologist working in close collaboration with various French instrument designers of the time. The objective of this article is twofold: (1) to show the considerable activity carried out by early psychologists to finalize new laboratory instruments in order to develop their research projects; (2) to reassess the work of a major figure in French psychology through his activity as a designer of precision instruments. The development of these new instruments would certainly have been difficult without the presence in Paris of numerous precision instrument manufacturers such as Charles Verdin, Otto Lund, Henri Collin, and Lucien Korsten, on whom Binet successively called in order to develop his projects in the field of experimental psychology.

    Jean-Martin Charcot (1825-1893) was the one of the world's leading physicians during the final third of the 19th century. Rewarded in 1882 with the creation of the first chair in the diseases of the nervous system, he was extremely successful at recruiting loyal and talented students. Charcot himself never produced a general treatise on hysteria, but instead encouraged his pupils to write their own books. Here, we describe how the work on hysteria of Georges Gilles de la Tourette, Paul Richer, Charles Féré and Alfred Binet was closely associated with Charcot, and how they remained faithful to their mentor. We will highlight the unusual personality of G. Gilles de la Tourette and the tragic end to his life, the exceptional artistic talent of P. Richer (writer and painter of his magnificently illustrated thesis), the prolific writing capacity of C. Féré (bearing witness to his broad fields of interest) and A. Binet (blessed with an extraordinary capacity for work, and author of The Psychology of Reasoning, before presenting his metric scale of intelligence).

    Both biochar application and mycorrhizal inoculation have been proposed to improve plant growth and alter bioaccumulation of toxic metals. A greenhouse pot trial was conducted to investigate growth and Cd accumulation of upland kangkong (Ipomoea aquatica Forsk.) intercropped with Alfred stonecrop (Sedum alfredii Hance) in a Cd-contaminated soil inoculated with Glomus caledonium and/or applied with biochar. Compared with the monocultural control, intercropping with stonecrop (IS) decreased kangkong Cd acquisition via rhizosphere competition, and also decreased kangkong yield. Gc inoculation (+M) accelerated growth and Cd acquisition of stonecrop, and hence resulted in further decreases in kangkong Cd acquisition. Regardless of IS and +M, biochar addition (+B) increased kangkong yield via elevating soil available P, and decreased soil Cd phytoavailability and kangkong Cd concentration via increasing soil pH. Compared with the control, the treatment of IS + M + B had a substantially higher kangkong yield (+25.5%) with a lower Cd concentration (−62.7%). Gc generated additive effects on soil alkalinization and Cd stabilization to biochar, causing lower DTPA-extractable (phytoavailable) Cd concentrations and post-harvest transfer risks. PMID:24728157

  12. The three lost millennia of the last deglaciation (Alfred Wegener Medal Lecture)

    NASA Astrophysics Data System (ADS)

    Bard, Edouard

    2013-04-01

    Looking back more than thirty years, climate history over the last period of deglaciation was seen to portray a smooth transition between the last glacial maximum (LGM) centered around 18,000 years ago (based on radiocarbon), and the beginning of the Holocene at about 10,000 years before present. At that time, the renowned CLIMAP group used the stratigraphy available to reconstruct the glacial world by averaging paleothermometric data over a wide time window, ranging between at least 14,000 and 24,000 yr BP, over which period climate was assumed to be rather stable. Even if northern European pollen records showed several phases of vegetation shift, the exact duration and spatial coverage of these shifts was unknown and their climatic significance was not well-enough understood to be separated from other biological effects, such as plant migration following ice-sheet demise. Significant progress came from mass spectrometry developments applied to isotope geochronology in the mid- and late- 1980s. This allowed the precise analysis of radiocarbon on small samples such as foraminifera in marine sediments and enabled the measurement of U-Th ages for accurate dating of corals and speleothems. These technological improvements permitted meaningful comparisons between proxy records from the various archives originating from all latitudes and longitudes.

    Looking back more than thirty years, climate history over the last period of deglaciation was seen to portray a smooth transition between the last glacial maximum (LGM) centered around 18,000 years ago (based on radiocarbon), and the beginning of the Holocene at about 10,000 years before present. At that time, the renowned CLIMAP group used the stratigraphy available to reconstruct the glacial world by averaging paleothermometric data over a wide time window, ranging between at least 14,000 and 24,000 yr BP, over which period climate was assumed to be rather stable. Even if northern European pollen records showed several phases of vegetation shift, the exact duration and spatial coverage of these shifts was unknown and their climatic significance was not well-enough understood to be separated from other biological effects, such as plant migration following ice-sheet demise. Significant progress came from mass spectrometry developments applied to isotope geochronology in the mid- and late- 1980s. This allowed the precise analysis of radiocarbon on small samples such as foraminifera in marine sediments and enabled the measurement of U-Th ages for accurate dating of corals and speleothems. These technological improvements permitted meaningful comparisons between proxy records from the various archives originating from all latitudes and longitudes. Today, it is clear that the old LGM time window corresponds to a period of more than ten millennia during which there was significant climate variability, including a prominent cooling event at the beginning of the deglaciation. This cooling event is known as the 'Oldest Dryas' by palynologists, as 'Heinrich Event #1' (H1) by paleoceanographers, and has even been dubbed the 'Mystery Interval' by prominent authors as they puzzled while attempting to synthesize and interpret its records.

    15 June 2004 Spring is upon the martian northern hemisphere, and the north polar cap is shrinking. This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image, acquired on 12 June 2004, shows the retreating edge of the seasonal north polar cap near 70oN, 209oW. Low clouds and fogs stream away from the cap edge as it sublimes away. North is approximately up and the image covers an area roughly 500 km (311 mi) across. Sunlight illuminates the scene from the lower left. The crater containing a thick mound of material near the right-center of the image is Korolev.

    Alfred E. Bergeat, originated from a family, who produced gold-glance in a factory (porcelain painting), studied mineralogy and geology at the University of Munich from 1886 to 1892. Due to the results of his habilitation work on the volcanism of island arcs, especially of the Stromboli volcanic island in the Tyrrhenian Sea, he became a recognized volcanologist and specialist in volcanic petrography. He further became an explorer of syngenetic, epigenetic and deuterogenic ore deposits at the mining academies (Bergakademien) of Freiberg (Saxony) and Clausthal (Harz mountains). He described these ore deposits in a two-volume manual (1904-1906) which was summarized again in 1913. After his early death in 1924, the two manuals “Die Vulkane” (1925) and “Vulkankunde” (1927) were posthumously published by his colleague and friend Karl Sapper (1866-1945).

  17. Swedenborg, Linnaeus and brain research--and the roles of Gustaf Retzius and Alfred Stroh in the rediscovery of Swedenborg's manuscripts.

    Emanuel Swedenborg (1688-1772) at the end of his long life became famous as a visionary mystic and founder of a new religion. However, at younger age, he was recognized as a prominent mining engineer and natural philosopher, particularly interested in geology, mineralogy, cosmology, paleontology and last but not least physiology of the brain. In his Oeconomica regni animalis (1740) and in several posthumously published extensive manuscripts, he described and analyzed e.g. the structural and functional organization of the cerebral cortex, the hierarchical construction of the nervous system, the localization of the cerebrospinal fluid and the secretory functions of the pituitary gland. In these fields, he presented remarkable insights and far reaching conclusions which in some cases have been experimentally verified in modern times. In spite of family relations Swedenborg rarely met the 19 years younger Linnaeus. Linnaeus was not only the founder of the systemic botany but as physician a keen and to some extent original observer of neurological symptoms; one of the first who adequately described motor aphasia. To regard these two men, among the few Swedish authors of the 18th century whose names are still internationally well known, as early precursors of neurological research, seems justified. The young Canadian, Alfred H. Stroh (1878-1922), had a crucial importance for the research on the works of Swedenborg, and the rediscovery of his manuscripts. His work was supported and financed to a large extent by professor Gustaf Retzius, at that time the most prominent Swedish researcher in anatomy and histology. There are many reasons to be thankful for the important contributions made by Alfred Stroh and Gustaf Retzius to stimulate the interest for Emanuel Swedenborg in Sweden and internationally.

    Root-knot nematodes (Meloidogyne spp.) are the most common and destructive plant-parasitic nematode group worldwide and adversely influence both crop quality and yield. In this study, a total of 51 root-knot nematode populations from turfgrasses were tested, of which 44 were from North Carolina, 6 from South Carolina and 1 from Virginia. Molecular characterisation was performed on these samples by DNA sequencing on the ribosomal DNA 18S, ITS and 28S D2/D3. Species-specific primers were developed to identify turfgrass root-knot nematode through simplex or duplex PCR. Four species were identified, including M. marylandi Jepson & Golden in Jepson, 1987, M. graminis (Sledge & Golden, 1964) Whitehead, 1968, M. incognita (Kofoid & White, 1919) Chitwood, 1949 and M. naasi Franklin, 1965 through a combined analysis of DNA sequencing and PCR by species-specific primers. M. marylandi has been reported from North Carolina and South Carolina for the first time. Molecular diagnosis using PCR by species-specific primers provides a rapid and cheap species identification approach for turfgrass root-knot nematodes. PMID:26599462

  20. Is There Really A North American Plate?

    Krill, A.

    2011-12-01

    Lithospheric plates are typically identified from earthquake epicenters and evidence such as GPS movements. But no evidence indicates a plate boundary between the North American and South American Plates. Some plate maps show them separated by a transform boundary, but it is only a fracture zone. Other maps show an "undefined plate boundary" or put no boundary between these two plates (check Google images). Early plate maps showed a single large American Plate, quite narrow east of the Caribbean Plate (Le Pichon 1968, Morgan 1968). The North and South American Plates became established by the leading textbook Earth (Press & Siever 1974). On their map, from a Scientific American article by John Dewey (1972), these new plates were separated by an "uncertain plate boundary." The reasons for postulating a North American Plate were probably more psychological than geological. Each of the other continents of the world had its own plate, and North American geologists naturally wanted theirs. Similarly, European geographers used to view Europe as its own continent. A single large plate should again be hypothesized. But the term American Plate would now be ambiguous ("Which plate, North or South?") Perhaps future textbook authors could call it the "Two-American Plate." Textbook authors ultimately decide such global-tectonic matters. I became aware of textbook authors' opinions and influence from my research into the history of Alfred Wegener's continental drift (see Fixists vs. Mobilists by Krill 2011). Leading textbook author Charles Schuchert realized that continental drift would abolish his cherished paleogeographic models of large east-west continents (Eria, Gondwana) and small oceans (Poseiden, Nereis). He and his junior coauthors conspired to keep drift evidence out of their textbooks, from the 1934-editions until the 1969-editions (Physical Geology by Longwell et al. 1969, Historical Geology by Dunbar & Waage 1969). Their textbooks ruled in America. Textbooks

    The United States (U.S.) and Canada will experience climate changes through direct effects of local changes (e.g., temperature, precipitation, and extreme weather events), as well as through indirect effects, transmitted among regions by interconnected economies and migrations of humans and other species. Variations in wealth and geography, however, lead to an uneven distribution of likely impacts, vulnerabilities, and capacities to adapt. This chapter reviews and synthesizes the state of knowledge on both direct and indirect impacts, vulnerability and adaptations for North America 9 (comprising Canada and the U.S).

    In the 1880s, Alfred Russel Wallace, the celebrated co-discoverer of natural selection, launched himself into the centre of a politicised and polarised debate over the unpopular compulsory vaccination laws in England. Wallace never wavered in his belief that smallpox vaccination was useless and likely dangerous. Six years before his death, the anti-vaccinationists successfully secured a conscience clause that effectively dismantled the compulsory vaccination laws. Several other important Victorian scientists joined Wallace in the fight to repeal compulsory vaccination arguing that widely held views on the effectiveness of vaccination and evidence for immunity were inconclusive in the light of (then) contemporary standards of evidence. This article situates Wallace's anti-vaccination logic within the broader matrix of sociopolitical and cultural reform movements of the late Victorian era. Additionally it provides the first detailed analysis of his critique of vaccination science, in particular the role statistics played in his arguments. In this period, both pro-vaccinationists and anti-vaccinationists invested great efforts in collating and analysing statistical data sets that either supported or refuted the claims of vaccination's effectiveness. While each side presented 'controlled' case studies to support their assertions, without an unambiguous test to measure or demonstrate vaccination's effectiveness, the anti-vaccinationists continued to mount credible statistical critiques of vaccination science.

    Understanding and identifying the spatial-temporal changes in the natural environment is crucial for monitoring and evaluating conservation efforts, as well as understanding the impact of human activities on natural resources, informing responsible land management, and promoting better decision-making. Conservation areas are often under pressure from expanding farming and related industry, invasive alien vegetation, and an ever-increasing human settlement footprint. This study focuses on detecting changes to the Prince Alfred Hamlet commonage, near Ceres in the Cape Floral Kingdom. It was chosen for its high conservation value and significance as a critical water source area. The study area includes a fast-growing human settlement footprint in a highly productive farming landscape. There are conflicting development needs as well as risks to agricultural production, and both of these threaten the integrity of the ecosystems which supply underlying services to both demands on the land. Using a multi-disciplinary approach and high-resolution satellite imagery, land use and land cover changes can be detected and classified, and the results used to support the conservation of biodiversity and wildlife, and protect our natural resources. The aim of this research is to study the efficacy of using remote sensing and GIS techniques to detect changes to critical conservation areas where disturbances can be understood, and therefore better managed and mitigated before these areas are degraded beyond repair.

    The Yemen Arab Republic, also called North Yemen, is a small republic on the southern tip of the Arabian peninsula facing the Red Sea. Yemen has a temperate interior suitable for agriculture. 8.7 million people of Semetic Arab origin are growing at a rate of 3.1% yearly. The infant mortality rate is 173/1000; the life expectancy is 44 years, and the per capita income is about $550. Yemen was once self-sufficient in food production, exporting fine coffee. Years of civil wars, emigration to Saudi Arabia for work, production of the cash crop "qat" for internal consumption, and the recent drought have contributed to the decline of agriculture. Yemen's economy is maintained by foreign aid from Saudi Arabia, the Soviet Union, China, and the United States. U.S. aid has centered around food, roads and other development projects and primary health care such as immunization and reduction of child mortality.

    Research into population declines of North American bird species has mainly focused on the fragmentation of habitat on the breeding or wintering grounds [Robinson, S. K., Thompson, F. R., Donovan, T. M., Whitehead, D. R. & Faaborg, J. (1995) Science 267, 1987-1990]. In contrast, research into declines of European species has mainly focused on intensification of agriculture [Donald, P. F., Green, R. E. & Heath, M. F. (2001) Proc. R. Soc. London Ser. B 268, 25-29] and the role played by the atmospheric deposition of pollutants, in particular, acid rain [Graveland, J. (1998) Environ. Rev. 6, 41-54]. However, despite widespread unexplained declines of bird populations in regions of heavy wet acid ion deposition [Sauer, J. R., Hines, J. E. & Fallon, J. (2001) The North American Breeding Bird Survey Results and Analysis 1966-2000 (Patuxent Wildlife Research Center, Laurel, MD)], no North American studies have presented evidence linking such widespread terrestrial bird declines to acid rain. To address the question of the role played by acid rain in population declines of eastern North American songbird species, we combine data from several sources. We use a multiple logistic regression model to test for adverse effects of acid rain on the Wood Thrush, while controlling for regional abundance, landscape-level habitat fragmentation, elevation, soil pH, and vegetation. We show a strong, highly significant, negative effect of acid rain on the predicted probability of breeding by this species, and interactions with elevation, low pH soils, and habitat fragmentation that worsen these negative effects. Our results suggest an important role for acid rain in recent declines of some birds breeding in the eastern United States, particularly in high elevation zones with low pH soils, and show the need to consider other large-scale influences, in addition to habitat fragmentation, when addressing bird population declines.

    While Alfred Vulpian (1826-1887) is not completely forgotten, he cannot match the uninterrupted celebrity which Jean-Martin Charcot (1825-1893) still enjoys today. After becoming interne (residents) at the same institute in 1848, both were involved in shaping the cradle of what would become modern neurology. Both started work as chiefs at a La Salpêtrière service on January 1, 1862, making common rounds and studies, with several common publications. While their friendship remained 'for life', as stated by Charcot at Vulpian's funeral, their career paths differed. Vulpian progressed quicker and higher, being appointed full professor and elected at the Académie Nationale de Médecine and the Académie des Sciences several years before Charcot, as well as becoming dean of the Paris Faculty of Medicine. These positions also enabled him to support his friend Charcot in getting appointed full clinical professor and becoming the first holder of the chair of Clinique des Maladies du Système Nerveux in 1882. Before studying medicine, Vulpian had worked in physiology with Pierre Flourens, and his career always remained balanced between physiology and neurology, with remarkable papers. He introduced Charcot to optic microscopy during their La Salpêtrière years, indirectly helping him to become his successor to the chair of pathological anatomy in 1872. While Vulpian succeeded so well in local medical affairs, Charcot spent his time building up a huge clinical service and a teaching 'school' at La Salpêtrière, which he never left for over 31 years until his death. This 'school' progressively became synonymous with clinical neurology itself and perpetuated the master's memory for decades. Vulpian never had such support, although Jules Déjerine was his pupil and Joseph Babinski was his interne before becoming Charcot's chef de clinique (chief of staff) in 1885. This unusual switch in Parisian medicine contributed to Charcot's unaltered celebrity over more than a century

Transmission to humans of North American arboviruses occurs by infected mosquitoes or ticks. Most infections are asymptomatic or produce a flu-like illness. Elderly, immunosuppressed individuals and infants for some arboviruses have the highest incidence of severe encephalitis. Rapid serum or CSF IgM antibody capture ELISA assays are now available to diagnosis the acute infection for all North American arboviruses. Unfortunately, no antiviral drugs are approved for the treatment of arbovirus infection and current therapy is supportive. PMID:18657724

    2006-01-01

    23 January 2006 This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows dark sand dunes in the north polar region of Mars. Surrounding much of the north polar ice cap are fields of sand dunes. In this case, the strongest winds responsible for the dunes blew off the polar cap (not seen here), from the north-northwest (upper left).

    NASA Astrophysics Data System (ADS)

    Molinari, R.; Bryan, K.; Schott, F.

    The intensity of the North Atlantic winddriven and thermohaline circulation and the close proximity of many oceanographic installations make the North Atlantic a particularly favored region of the world ocean from the standpoint of research in ocean circulation. Recent increases in available data and advances in numerical modeling techniques served as the impetus to convene a joint workshop of modelers and observers working on the North Atlantic with the Scientific Committee on Oceanic Research (SCOR) Working Group (WG) 68 (“North Atlantic Circulation”). Goals of the workshop were to provide an update on data sets and models and to discuss the poleward heat flux problem and possible monitoring strategies. The joint Workshop/SCOR WG-68 meeting was convened by F. Schott (chairman of the working group; Rosenstiel School of Marine and Atmospheric Science, Miami, Fla.), K. Bryan (National Oceanic and Atmospheric Administration/ Geophysical Fluid Dynamics Laboratory (NOAA/GFDL)), and R. Molinari (NOAA/Atlantic Oceanographic and Meteorological Laboratory (NOAA/AOML)).

    NASA Technical Reports Server (NTRS)

    2004-01-01

    25 December 2004 For 25 December, the MOC team thought that a visit to a north polar site would be timely. This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows, at about 1.5 meters per pixel (5 feet per pixel) resolution, a view of the north polar ice cap of Mars. That the material includes water ice has been known since the mid-1970s, when Viking orbiter observations confirmed that the cap gives off water vapor in the summertime, as the ice is subliming away. The surface shown here, observed by MOC during northern summer in November 2004, is pitted and somewhat grooved. Dark material on pit floors might be trapped, windblown dust. The picture covers an area about 1 km (0.62 mi) across, and is located near 86.8oN, 293.1oW. Sunlight illuminates the scene from the lower left.

Wind streaks are also evident in this summertime scene. The layers that make up the material beneath the ice of the north polar residual cap are typically considered to be a mixture of some amount of dust and ice, but the proportions of these constituents are not known.

The surface is pitted and rough at the scale of several meters. The north polar residual cap of Mars consists mainly of water ice, while the south polar residual cap is mostly carbon dioxide. This picture is located near 85.2oN, 283.2oW. The image covers an area approximately 1 km wide by 1.4 km high (0.62 by 0.87 miles). Sunlight illuminates this scene from the lower left.

    2004-01-01

    28 November 2004 This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows banded terrain of the north polar region of Mars. The bands are exposures of layered material, possibly composed of dust and ice. The dark, rounded to elliptical mounds in this image might be the locations of ancient sand dunes that were completely buried in the north polar layered material. In more recent times, these mounds have been exhumed from within the layered material. Alternatively, the dark features are not ancient, exhumed dunes, but perhaps the remnants of a dark layer of material that once covered the entire area shown in the image. These features are located near 79.9oN, 31.4oW. The image covers an area about 3 km (1.9 mi) wide. Sunlight illuminates the scene from the lower left.

    2003-01-01

    This anaglyph (stereoscopic view) of North America was generated with data from the Shuttle Radar Topography Mission (SRTM). It is best viewed at or near full resolution with anaglyph glasses. For this broad view the resolution of the data was first reduced to 30 arcseconds (about 928 meters north-south and 736 meters east-west in central North America), matching the best previously existing global digital topographic data set called GTOPO30. The data were then resampled to a Mercator projection with approximately square pixels (about one kilometer, or 0.6 miles, on each side). Even at this decreased resolution the variety of landforms comprising the North American continent is readily apparent.

    Active tectonics (structural deformation of the Earth's crust) along and near the Pacific North American plate boundary creates the great topographic relief seen along the Pacific coast. Earth's crustal plates converge in southern Mexico and in the northwest United States, melting the crust and producing volcanic cones. Along the California coast, the plates are sliding laterally past each other, producing a pattern of slices within the San Andreas fault system. And, where the plates are diverging, the crust appears torn apart as one huge tear along the Gulf of California (northwest Mexico), and as the several fractures comprising the Basin and Range province (in and around Nevada).

    Across the Great Plains, erosional patterns dominate, with stream channels surrounding and penetrating the remnants of older smooth slopes east of the Rocky Mountains. This same erosion process is exposing the bedrock structural patterns of the Black Hills in South Dakota and the Ozark Mountains in Arkansas. Lateral erosion and sediment deposition by the Mississippi River has produced the flatlands of the lower Mississippi Valley and the Mississippi Delta.

    To the north, evidence of the glaciers of the last ice age is widely found, particularly east of the Canadian Rocky Mountains and

  20. The Nazi ethnographic research of Georg Leibbrandt and Karl Stumpp in Ukraine, and its North American legacy.

    Schmaltz, E J; Sinner, S D

    2000-01-01

    Scholars have recently debated the topic of German academics who directly or indirectly served the Nazi machinery of death and who then went on to successful professional careers after the war. This article examines the activities of two prominent émigré scholars, Drs. Georg Leibbrandt (1899-1982) and Karl Stumpp (1896-1982). These Ukrainian Germans emigrated to Germany after World War 1. In America, most members of the Russian-German ethnic community never knew that Leibbrandt had represented Alfred Rosenberg's Ministry for the Occupied Eastern Territories, or that under his supervision Stumpp led a Sonderkommando in Ukraine. This unit classified hundreds of villages, indirectly documenting the annihilation of Jews and others. The authors conclude that one consequence of Leibbrandt's and Stumpp's "return to normalcy" after the war was the growing fascination with genealogical research that affected the Russian-German ethnic community in North America-research partly based on 1930s and 1940s Nazi racial record-keeping.

    Plant phenological observations and networks in North America have been largely local and regional in extent until recent decades. In the USA, cloned plant monitoring networks were the exception to this pattern, with data collection spanning the late 1950s until approximately the early 1990s. Animal observation networks, especially for birds have been more extensive. The USA National Phenology Network (USA-NPN), established in the mid-2000s is a recent effort to operate a comprehensive national-scale network in the United States. In Canada, PlantWatch, as part of Nature Watch, is the current national-scale plant phenology program.

    Why does Fargo flood? The Red River of the North, which forms the border between North Dakota and Minnesota, has a long history of severe floods. Major floods include those of 1826, 1897, 1950, 1997, and now 2009. The 1997 flood caused billions of dollars of damage, with greatest impact to the city of Grand Forks, north of and downstream from Fargo. The 2009 flood, which has primarily impacted Fargo, appears to have peaked early on March 28.

    Several factors combine to cause floods. Obviously, rainfall and snowmelt rates (and their geographic distribution) are the fundamental variables that create flooding in some years and not others. But the repetition of flooding in Fargo (and areas downstream), rather than in adjacent regions, can be attributed largely to its topographic setting and geologic history.

    The formation of landforms in the geologic past is often interpretable from digital topographic data, such as that supplied by the Shuttle Radar Topography Mission (SRTM). This image, covering parts of North Dakota, Minnesota, and South Dakota, displays ground elevation as brightness (higher is brighter) plus has simulated shading (with illumination from the north) to enhance topographic detail such as stream channels, ridges, and cliffs.

    The Red River of the North is the only major river that flows northward from the United States into Canada. In this scene it flows almost straight north from Fargo. North of this image it continues past the city of Winnipeg, Manitoba, and into Lake Winnipeg, which in turn drains to Hudson Bay. In the United States, the river lies in a trough that was shaped by continental glaciers that pushed south from Canada during the Pleistocene epoch, up to about 10,000 years ago. This trough is about 70 km (45 miles) wide and tens of meters (very generally about 100 feet) deep. Here near Fargo it lies on

  7. North Atlantic Bloom

    NASA Technical Reports Server (NTRS)

    2007-01-01

    Reminiscent of the distinctive swirls in a Van Gogh painting, millions of microscopic plants color the waters of the North Atlantic with strokes of blue, turquoise, green, and brown. Fed by nutrients that have built up during the winter and the long, sunlit days of late spring and early summer, the cool waters of the North Atlantic come alive every year with a vivid display of color. The microscopic plants, called phytoplankton, that give the water this color are the base of the marine food chain. Some species of phytoplankton are coated with scales of calcium (chalk), which turn the water electric blue. Chlorophyll and other light-capturing pigments in others give the water a deep green hue. The proliferation of many different species in various stages of growth and decay provides many nuances of color in this concentrated bloom. The bloom stretches across hundreds of kilometers, well beyond the edges of this photo-like image, captured on June 23, 2007, by the Moderate Resolution Imaging Spectroradiometer (MODIS) flying aboard NASA's Aqua satellite. The upper left edge of the image is bounded by Greenland. Iceland is in the upper right. Plumes of dust are blowing off the island, probably adding nutrients to the surface waters to its south.

  9. North Polar Ice Cap

    NASA Technical Reports Server (NTRS)

    1997-01-01

    North polar ice cap of Mars, as seen during mid summer in the northern hemisphere. The reddish areas consist of eolian dust, bright white areas consist of a mixture of water ice and dust, and the dark blue areas consist of sand dunes forming a huge 'collar' around the polar ice cap. (The colors have been enhanced with a decorrelation stretch to better show the color variability.) Shown here is an oblique view of the polar region, as seen with the Viking 1 spacecraft orbiting Mars over latitude 39 degrees north. The spiral bands consist of valleys which form by a combination of the Coriolis forces, wind erosion, and differential sublimation and condensation. In high-resolution images the polar caps are seen to consist of thick sequences of layered deposits, suggesting that cyclical climate changes have occurred on Mars. Cyclical climate changes are readily explained by quasi-periodic changes in the amount and distribution of solar heating resulting from perturbations in orbital and axial elements. Variations in the Earth's orbit have also been linked to the terrestrial climate changes during the ice ages.

    1998-01-01

    This radar image shows the dramatic landscape in the Phang Hoei Range of north central Thailand, about 40 kilometers (25 miles) northeast of the city of Lom Sak. The plateau, shown in green to the left of center, is the area of Phu Kradung National Park. This plateau is a remnant of a once larger plateau, another portion of which is seen along the right side of the image. The plateaus have been dissected by water erosion over thousands of years. Forest areas appear green on the image; agricultural areas and settlements appear as red and blue. North is toward the lower right. The area shown is 38 by 50 kilometers (24 by 31 miles) and is centered at 16.96 degrees north latitude, 101.67 degrees east longitude. Colors are assigned to different radar frequencies and polarizations as follows: red is L-band horizontally transmitted and horizontally received; green is L-band horizontally transmitted and vertically received; blue is C-band horizontally transmitted and vertically received. The image was acquired by the Spaceborne Imaging Radar-C/X-band Synthetic Aperture (SIR-C/X-SAR) imaging radar on October 3, 1994, when it flew aboard the space shuttle Endeavour. SIR-C/X-SAR is a joint mission of the U.S./German and Italian space agencies.

    Spaceborne Imaging Radar-C and X-Band Synthetic Aperture Radar (SIR-C/X-SAR) is part of NASA's Mission to Planet Earth. The radars illuminate Earth with microwaves allowing detailed observations at any time, regardless of weather or sunlight conditions. SIR-C/X-SAR uses three microwave wavelengths: L-band (24 cm), C-band (6 cm) and X-band (3 cm). The multi-frequency data will be used by the international scientific community to better understand the global environment and how it is changing. The SIR-C/X-SAR data, complemented by aircraft and ground studies, will give scientists clearer insights into those environmental changes which are caused by nature and those changes which are induced by human activity. SIR-C was developed by

    Richardson, Randall M.; Reding, Lynn M.

    1991-01-01

    Deformation within the North American plate in response to various tectonic processes is modeled using an elastic finite element analysis. The tectonic processes considered in the modeling include ridge forces associated with the normal thermal evolution of oceanic lithosphere, shear and normal stresses transmitted across transforms, normal stresses transmitted across convergent boundaries, stresses due to horizontal density contrasts within the continent, and shear tractions applied along the base of the plate. Model stresses are calculated with respect to a lithostatic reference stress state. Shear stresses transmitted across transform boundaries along the San Andreas and Caribbean are small, of the order of 5-10 MPa. Also, compressive stresses of the order of 5-10 MPa transmitted across the major transforms improve the fit to the data. Compressive stresses across convergent margins along the Aleutians and the Middle America trench are important.

    1984-01-01

    The North Absaroka Wilderness in Wyoming was studied to evaluate the resource potential of the area. The results of geologic field mapping, field inspection of claims and prospects, analyses of bedrock and stream-sediment samples, and an aeromagnetic survey indicate that a small area of geologic terrane with probable mineral-resource potential for silver, lead, and zinc is present on the northern edge of the wilderness. Bentonite, low-quality coal, and localized deposits of uranium and chromite have been produced from surrounding areas; but such deposits, if present in the wilderness, are probably too deeply buried, too small, or too sporadically distributed to be classed as resources. Copper and gold mines and prospects are present on the fringes of the wilderness, but otherwise the area seems to be devoid of concentrations of metallic minerals. No surface evidence of geothermal energy resources was found.

    This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image is a springtime view of frost-covered layers revealed by an eroded scarp in the martian north polar cap. The layers are thought to consist of a mixture of dust, ice, and possibly sand. Some layers are known to be a source for dark sand that occurs in nearby dunes. During the summer, this surface would be considerably darker because most of the bright frost sublimes away during the spring season. The picture covers an area about 3 km (1.9 mi) wide near 85.2oN, 4.4oW. Sunlight illuminates the scene from the lower left.

    3 December 2004 This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows an exposure of finely-detailed layers in the martian north polar region. The polar ice cap, which is made up of frozen water (whereas the south polar cap is mostly frozen carbon dioxide), is underlain by a thick sequence of layers. Some have speculated that these layers may record the history of changes in martian climate during the past few hundreds of millions of years. This picture is located near 86.0oN, 30.2oW, and covers an area approximately 3 km (1.9 mi) across. Sunlight illuminates the scene from the lower left.

  4. The North Pacific Gyre Mode

    NASA Astrophysics Data System (ADS)

    Schneider, N.; di Lorenzo, E.

    2007-12-01

    Discussion of North Pacific Decadal decadal variability has focused primarily on the Pacific Decadal Oscillation, the leading mode of sea surface temperature anomalies north of the tropics. The PDO appears to result from a superposition of SST pattern forced by the North Pacific atmosphere due to its intrinsic dynamics and teleconnected from the tropics, with a regional impact of the ocean circulation in the frontal regions associated with the Kuroshio/Oyashio and their extensions into the interior. Recent modeling, however, suggest that previously unexplained decadal changes of salinity, nutrient upwelling and chlorophyl in the California Current are not dominated by the PDO. Rather, these are associated with a mode of variability associated with wind driven changes of the North Pacific Gyre. Consideration of this mode variability may thus be important to understand present and future variations of the North Pacific ecosystem, and in the interpretation of climate proxies.

    It is widely accepted, that Pasteur's seminal discovery of the opposite optical activity of ammonium sodium tartrate enantiomorphs in solution gave the spark to organic stereochemistry and led to the development of the tetrahedron model by van't Hoff and Le Bel. The proof that chirality is inherently connected to octahedral coordination chemistry fostered greatly Werner's spatial views of metal complexes and his coordination theory. The actual proof of principle was established via separation of diastereomeric camphor sulfonate salts of racemic metal complexes. PMID:20928897

  10. [Sigmund Freud's ambition and Alfred Adler].

    PubMed

    Lebzeltern, G

    1984-11-01

    Freud never admitted to himself that he possessed a greater-than-average sense of ambition, which manifested itself in dreams, malachievement and priority problems. A completely new picture of Freud arises from such a perspective. Freud experienced childhood trauma in the form of his relationship with his nephew, John, in whom both an intimate friend and hated enemy were incorporated. This experience left a life-long impression which predetermined the neurotic element in Freud's relationship with men. Freud's own interpretation being that he had been betrayed by Breuer, Fliess, Adler and Jung. That is why the sentencing of his Uncle Joseph to a term of imprisonment had such far-reaching consequences for Freud. A further noteworthy observation is the close connection between ambition and death wishes and also between ambition and guilt feelings. Who, after all, likes to admit to harbouring such feelings? It appeared necessary to investigate the extent to which Freud's excessive ambition influenced his relationships with Breuer, Fliess and Adler. Freud was never prepared to recognize that Adler's contribution consisted of revealing the importance of the natural laws governing those layers of the psyche nearer to the conscious. The picture of the whole person emerges only by a combination of psychoanalysis and individual psychology.

  12. North Sea platforms revamped

    SciTech Connect

    O'Hare, J.

    1999-12-01

    Many of the early North Sea platforms are reaching their end-of-field life. Most are still equipped with their original drilling package. In a few cases the package has either been removed or decommissioned. The early installations were designed for much simpler and less demanding wells than the horizontal, extended-reach or designer wells common today. Extended-reach wells now can be drilled realistically from ageing platforms, without incurring massive capital expenditure. This can be achieved using the existing drilling package to the limit of its capabilities and supplementing where necessary with relatively minor upgrades or the use of temporary equipment. Drilling even a few more wells from existing platforms not only prolongs field life, it enables any surplus processing capacity to be made available to develop near-field potential with extended-reach drilling (ERD) or by tying back subsea satellite wells, or for processing third-party fluids. The paper describes well design, surface equipment, mud pumps, shakers and solids control equipment, drill cuttings disposal systems, derrick and hoisting system, top drive and drillstring, downhole equipment, well planning, casing wear, logistics, rig preparations, and ERD vs. subsea tie-backs.

  13. Blogging from North Pond

    Marziali, C. G.; Edwards, K. J.

    2009-12-01

    Sea going research expeditions provide an ideal opportunity for outreach through blogs: the finite duration limits the author's commitment; scientists are usually in a remote location with fewer distractions; and fieldwork is visual and interesting to describe. Over four weeks this winter, Katrina Edwards of USC authored a blog about her deep-sea drilling expedition to North Pond, a depression in the ocean crust in the mid-Atlantic. She emailed daily dispatches and photos to USC Media Relations, which maintained a (still accessible) blog. Written for the general public, the blog quickly attracted interest from lay readers as well as from media organizations. Scientific American carried the blog on its web site, and the National Science Foundation linked to it in its "Science 360" electronic news digest. The blog also led to a Q&A with Edwards in the widely-read "Behind the Scenes" feature of LiveScience. Interest from science bloggers and National Geographic towards the end suggests that the blog could have expanded its reach given more time: expeditions lasting between six weeks and three months, such as occur during ocean drilling expeditions, would appear to be ideal candidates for a blog. Most importantly, the blog educated readers about the importance to planetary life of what Edwards calls the "intraterrestrials": the countless microbes that inhabit the oceanic crust and influence major chemical and biological cycles. Considering that the subjects of the expedition were invisible critters in a pitch-dark place, the blog shows what can be accomplished by scientists and institutions committed to public outreach.

  14. North Nilosyrtis Mensae

    NASA Technical Reports Server (NTRS)

    1999-01-01

    This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image was obtained during the first week of June 1999. It shows a portion of the Nilosyrtis Mensae region, located north of Syrtis Major and southwest of Utopia Planitia. This region is part of a planet-wide transition zone that separates the high, cratered terrain of the southern two thirds of Mars from the low, relatively uncratered northern plains. Old remnants of the cratered highlands are common in this transition zone, and they are usually in the form of mesas and buttes.

    The MOC image shows several low, flat-topped mesas. Although flat at large scale, their surfaces are quite rough and bumpy at smaller scales. Many of these bumps might be boulders, but the resolution of this particular image (4.5 meters--15 feet--per pixel) is not high enough to be certain. The lowlands surrounding the mesas are cracked and pitted--especially the darker surfaces on the right side of the image. The cause of the pitting is not known and can only be speculated upon (because the material removed from each pit is now gone). Possible origins for the pits include removal of dust or sand by wind and/or sublimation of ice from the near subsurface. The picture covers an area 3 kilometers (1.9 miles) wide and is illuminated from the left.

    Malin Space Science Systems and the California Institute of Technology built the MOC using spare hardware from the Mars Observer mission. MSSS operates the camera from its facilities in San Diego, CA. The Jet Propulsion Laboratory's Mars Surveyor Operations Project operates the Mars Global Surveyor spacecraft with its industrial partner, Lockheed Martin Astronautics, from facilities in Pasadena, CA and Denver, CO.

  18. Seismicity of California's north coast

    USGS Publications Warehouse

    Bakun, W.H.

    2000-01-01

    At least three moment magnitude (M) 7 earthquakes occurred along California's north coast in the second half of the nineteenth century. The M 7.3 earthquake on 23 November 1873 occurred near the California-Oregon coast and likely was located on the Cascadia subduction zone or within the North American plate. The M 7.0 + earthquake on 9 May 1878 was located about 75 km offshore near the Mendocino fault. The surface-wave magnitude (M(s)) 7.0 earthquake on 16 April 1899 was located about 150 km offshore within the Gorda plate. There were at least three M 7 north-coast earthquakes in the 35 years before 1906, two M 7 earthquakes in the 20 years after 1906, no M 7 earthquakes from 1923 until 1980, and four M 7 earthquakes since 1980. The relative seismic quiescence after 1906 for M 7 earthquakes along California's north coast mimics the post-1906 seismic quiescence in the San Francisco Bay area for M 6 earthquakes. The post-1906 relative quiescence did not extend to lower magnitudes in either area. The 18 April 1906 earthquake apparently influenced the rate of occurrence of M 7 north-coast earthquakes as it apparently influenced the rate of M 6 earthquakes in the San Francisco Bay area. The relative seismic quiescence along the California north-coast region after 1906 should be taken into account when evaluating seismic hazards in northwest California.

  5. The North Korean nuclear dilemma.

    SciTech Connect

    Hecker, Siegfried S.

    2004-01-01

    The current nuclear crisis, the second one in ten years, erupted when North Korea expelled international nuclear inspectors in December 2002, then withdrew from the Nuclear Nonproliferation Treaty (NPT), and claimed to be building more nuclear weapons with the plutonium extracted from the spent fuel rods heretofore stored under international inspection. These actions were triggered by a disagreement over U.S. assertions that North Korea had violated the Agreed Framework (which froze the plutonium path to nuclear weapons to end the first crisis in 1994) by clandestinely developing uranium enrichment capabilities providing an alternative path to nuclear weapons. With Stanford University Professor John Lewis and three other Americans, I was allowed to visit the Yongbyon Nuclear Center on Jan. 8, 2004. We toured the 5 MWe reactor, the 50 MWe reactor construction site, the spent fuel pool storage building, and the radiochemical laboratory. We concluded that North Korea has restarted its 5 MWe reactor (which produces roughly 6 kg of plutonium annually), it removed the 8000 spent fuel rods that were previously stored under IAEA safeguards from the spent fuel pool, and that it most likely extracted the 25 to 30 kg of plutonium contained in these fuel rods. Although North Korean officials showed us what they claimed was their plutonium metal product from this reprocessing campaign, we were not able to conclude definitively that it was in fact plutonium metal and that it came from the most recent reprocessing campaign. Nevertheless, our North Korean hosts demonstrated that they had the capability, the facility and requisite capacity, and the technical expertise to produce plutonium metal. On the basis of our visit, we were not able to address the issue of whether or not North Korea had a 'deterrent' as claimed - that is, we were not able to conclude that North Korea can build a nuclear device and that it can integrate nuclear devices into suitable delivery systems.

Our picture is based on a synthesis of a variety of independent investigations that are contained in the literature as opposed to a presentation of the results of one technique or the point of view of one author. We describe a thermohaline cell (the so-called thermohaline conveyor belt) that is concentrated within the Atlantic and Southern oceans (rather than essentially global), with the most important upwelling sites being in the circumpolar and the equatorial current regimes. We concentrate on deep water formation and its replacement relative to intermediate-water formation. It has been pointed out recently that the formation of 13 Sv (1 Sv = 106 m³ s-1) of southward flowing North Atlantic Deep Water is compensated for in the upper ocean by northward cross-equatorial transport. We suggest that this thermocline layer flow passes through the Straits of Florida, transits the Gulf Stream system on its inshore side, and exits through the North Atlantic Current system after recirculation and modification. There is now a clear observational basis for the structure of recirculating gyres on the southern and northern sides of the Gulf Stream. We suggest a recirculation for the North Atlantic Current as well. We also describe a C-shaped component to the southern Gulf Stream recirculation and identify a roughly 10-Sv circulation in the eastern North Atlantic associated with the Azores Current. Recirculations play an important role in deep boundary current regimes and in water mass formation and modification. The transport of the deep western and northern boundary currents in the North Atlantic Ocean may be boosted (roughly doubled or tripled) by counterclockwise recirculating gyres and by additions of

    Since Alfred Wegener proposed the theory of continental drift more than a century ago, continuous effort to reconstruct the super continent Pangea has been carried out paleo-geographically during past several decades. Although a remarkable success has been achieved, there remains still a great uncertainty on the precise location and fits of the continents that constitute the Pangea. While the fits are recognized as quite complete for Gondwana, the northern part of Pangea, the fits for Laurasia which contains North Ameraica and Eurasia, are left with a lot of improvement. What the two giant continents look like when they were fitted to form the Pangea is also a unsolved question. Several hypothesis for the fits of Laurasia and Gondwana have been raised, and the scenarios of Pangea A1, Pangea A2, Pangea B, and Pangea C were proposed hitherto. Recently, an updated version very close to Pangea A2 was suggested by authors including Van der Voo, Trond H. Torsvik, which have improved several deficiencies of the Pangea A2. However, it was found that the new scenario cannot be fully supported by the paleomagnetism data. Furthermore, it is not in complete agreement with previous paleogeological surveys on major geological features such as Variscan and Caledonian orogenic belt, indicating that a more sophisticated scenario is needed still for the Pangea. The purpose of this study is to reconstruct the continents in western central Pangea with a focus on the Mediterranean and North Atlantic Ocean. A new fit of continents to form the Pangea is proposed, where the continents are fitted with enhanced accuracy compared to other models of Pangea particularly for the Mediterranean Sea, central America, Iran Plateau etc.. The results suggest that the continents were not distorted significantly on the process of drifting and merging during the past 200 million years.

  18. The north Sulu Sea productivity

    The Sulu Sea is a part of the western North Pacific. It is a closed sea for its deep water and a semi-closed sea for its upper layer. The Sulu Sea exchanges mainly surface waters with the South China Sea and the Celebes Sea. The Sulu Sea is more productive than the adjacent South China Sea (Jones, 2002). On the basis of MERIS satellite observations from 2002 to 2008, we focus on the high-chlorophyll area as an indicator of the abundance of primary productivity in the Sulu Sea. Strong chlorophyll concentration in the north Sulu Sea close to the Mindoro Strait mainly occurs from December to March and low chlorophyll concentration happens in April to November. The adjacent South China Sea on the other side of Mindoro Strait has shown persistent signs of low chlorophyll concentration. Based on 1/8° Global Navy Coastal Ocean Model, the intrusion of the South China Sea waters through the Mindoro Strait to the Sulu Sea from April to November is the main reason for the low chlorophyll concentration observed in the north Sulu Sea. During April to November, the South China Sea waters flow through the Mindoro Strait and stay on the surface of the north Sulu Sea because of their low density. The north Sulu Sea waters mix with fresher waters coming from the South China Sea without new nutrients supply. When the inflow from South China Sea to Sulu Sea ceases in December to March, the upwelling due to the summer monsoon wind becomes an important mechanism supplying deep nutrients to the surface water which lead to high chlorophyll concentration.

  19. Conservation of North American rallids

    1988-01-01

    The Rallidae are a diverse group in their habitat selection, yet most North American species occur in or near wetlands As a consequence, most species are subject to habitat enhancement or perturbation from waterfowl management programs. The overall effects of these management programs relative to rallid conservation have been assessed for few species, and there is a need for synthesis of such information. In the cases of some species or raves, population status is not known, and suggested directions for conservation and management are needed. Rare, endangered, or status undetermined species or races often occur in areas where related species are classified as game birds, and the effects of such hunting on rarer forms are not known. Their generally secretive nature, the endangered status of several races and populations, and continued loss of habitat and threats to present habitat, warrant an examination of the conservation status of the North American taxa in this group. In 1977, a committee of the International Association of Fish and Wildlife Agencies summarized available information on management and biology of American Coots (Fulica americana), rails, and gallinules in North America (Holliman 1977). That summary was intended to provide relatively complete information on conservation of these species, and also to provide guidance for research within the U.S. Fish and Wildlife Service's (FWS) Accelerated Research Program for Webless Migratory Shore and Upland Game Birds (ARP). Subsequently, a number of rallid studies were funded under this program. The program was eliminated in 1982, following substantial research activities on North American rallids. Since the demise of the ARP, additional research on rallids in North America has focused on an area the International Association of Fish and Wildlife Agencies report failed to cover in detail--that of endangered rallids in the U.S. and their possessions. Most of these studies have been of threatened and endangered

    2004-01-01

    15 October 2004 It is now early summer in the northern hemisphere on Mars, and this means that the ices of the north polar cap are in full retreat. Exposed from beneath seasonal frost are the eroded layers of what Mars scientists suspect are composed of a mixture of dust and ice (and in some layers, sand). This October 2004 Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows some of the north polar layers exposed on a moderately-dipping slope. The bright material at the top of the image is water ice frost; the triangular features are thought to be caused by wind erosion of the frost. This image is located near 87.1oN, 267.4oW, and covers an area about 3 km (1.9 mi) wide. Sunlight illuminates the scene from the lower left.

    A summary for North Atlantic circulation is proposed to replace the circulation scheme hypothesized by Worthington in 1976. Divergences from the previous model are in thermohaline circulation, cross-equatorical transport and Florida Current sources, flow in the eastern Atlantic, circulation in the Newfoundland Basin, slope water currents, and flow pattern near the Bahamas. The circulation patterns presented here are consistent with the majority of of published accounts of flow components. 77 refs., 14 figs., 3 tabs.

    The North Carolina Field Test will test the effectiveness of two weatherization approaches: the current North Carolina Low-Income Weatherization Assistance Program and the North Carolina Field Test Audit. The Field Test Audit will differ from North Carolina's current weatherization program in that it will incorporate new weatherization measures and techniques, a procedure for basing measure selection of the characteristics of the individual house and the cost-effectiveness of the measure, and also emphasize cooling energy savings. The field test will determine the differences of the two weatherization approaches from the viewpoints of energy savings, cost effectiveness, and implementation ease. This Experimental Plan details the steps in performing the field test. The field test will be a group effort by several participating organizations. Pre- and post-weatherization data will be collected over a two-year period (November 1989 through August 1991). The 120 houses included in the test will be divided into a control group and two treatment groups (one for each weatherization procedure) of 40 houses each. Weekly energy use data will be collected for each house representing whole-house electric, space heating and cooling, and water heating energy uses. Corresponding outdoor weather and house indoor temperature data will also be collected. The energy savings of each house will be determined using linear-regression based models. To account for variations between the pre- and post-weatherization periods, house energy savings will be normalized for differences in outdoor weather conditions and indoor temperatures. Differences between the average energy savings of treatment groups will be identified using an analysis of variance approach. Differences between energy savings will be quantified using multiple comparison techniques. 9 refs., 8 figs., 5 tabs.

    Market hunting and poor stewardship led to record low numbers of geese in the early 1900's, but regulated seasons including closures, refuges, and law enforcement led to restoration of most populations. Winter surveys were begun to study population trends and set responsible harvest regulations for these long-lived and diverse birds. Winter surveys begun in 1936-37 probably represent the oldest continuing index of migratory birds in North America.

  4. North Pacific High: an hypothesis

    NASA Astrophysics Data System (ADS)

    Kenyon, Kern E.

    An hypothesis is offered for the cause and maintenance of the North Pacific High (NPH). Over a broad but well defined open ocean area, in the mid-latitude North Pacific, the ocean heats the atmosphere from below, and outside the boundaries of the heat source the ocean cools the air at the sea surface. Vertical thermal convection in the air over the heat source brings down relatively cool dry air, producing a horizontal contrast mainly in relative humidity inside and outside the heat source region. Consequently relatively high density air is produced over the heat source, and if the temperature is approximately constant, then the barometric pressure will be high over the heat source as well. Being unstable, due to a horizontal pressure gradient, the high density air will try to move radially outward from the heat source, and the Coriolis force will bend the outward flow into a clockwise circulation around the center of high pressure. The heat source is provided by a broad northeastward warm surface current, previously described, that crosses mid-latitudes on the eastern side of the North Pacific at all times of the year. Given the known characteristics of the warm current, the heat source mechanism can explain the observed seasonal variations of the NPH also. A more complete substantiation (or refutation) of the general hypothesis for the origin of the NPH must await the accumulation of additional oceanic and atmospheric data.

  7. Diseases in North Sea fishes

    NASA Astrophysics Data System (ADS)

    Dethlefsen, V.

    1984-03-01

    Prior to the studies reviewed here, only lymphocystis and skeletal deformities of a variety of fish species and certain diseases of eel were known to occur in the German Bight (North Sea). From 1977 until now, 9 externally visible lesions on North Sea fishes were observed; in addition to those mentioned before, they comprise: fin rot, ulcerations, epidermal papilloma, hyperplasia, pseudobranchial tumour, eye diseases and gill swellings. With the exception of information on changes in frequencies of vertebral deformities of herring from the 1950's to the 1970's, there are no long-term data characterizing changes in frequencies of the diseases under study. For pseudobranchial tumours of cod and epidermal papilloma of dab, information is provided on occurrence and abundance. The distribution pattern of cod afflicted with pseudobranchial tumours is strongly influenced by the migratory behaviour of the fish. Epidermal papillomas of dab were more frequently found at stations within the inner German Bight than in neighbouring areas. The Bight is used for dumping of wastes from titaniumdioxide production. Further disease hot spots are areas off the Humber estuary and the British coast. Analysis of chromium in dab from the German Bight revealed elevated concentrations in epidermal tissues of specimens from the dumping area compared with that found in dab from neighbouring localities. Particulate iron was demonstrated to occur in mucous cells of dab from the dumping area. From increased levels of heavy metals with cancerogenic potential in sensitive target tissues and from increased prevalences of diseased fish in the dumping area it is concluded that these phenomena are possibly causally linked. In the vicinity of the Humber estuary high disease rates were encountered and areas with high prevalences of dab afflicted with epidermal papilloma extended over regions shown to be transport routes for persistent pollutants such as radioactive materials. It is therefore suggested

  8. Heart failure in North America.

    Blair, John E A; Huffman, Mark; Shah, Sanjiv J

    2013-05-01

    Heart failure is a major health problem that affects patients and healthcare systems worldwide. Within the continent of North America, differences in economic development, genetic susceptibility, cultural practices, and trends in risk factors and treatment all contribute to both inter-continental and within-continent differences in heart failure. The United States and Canada represent industrialized countries with similar culture, geography, and advanced economies and infrastructure. During the epidemiologic transition from rural to industrial in countries such as the United States and Canada, nutritional deficiencies and infectious diseases made way for degenerative diseases such as cardiovascular diseases, cancer, overweight/obesity, and diabetes. This in turn has resulted in an increase in heart failure incidence in these countries, especially as overall life expectancy increases. Mexico, on the other hand, has a less developed economy and infrastructure, and has a wide distribution in the level of urbanization as it becomes more industrialized. Mexico is under a period of epidemiologic transition and the etiology and incidence of heart failure is rapidly changing. Ethnic differences within the populations of the United States and Canada highlight the changing demographics of each country as well as potential disparities in heart failure care. Heart failure with preserved ejection fraction makes up approximately half of all hospital admissions throughout North America; however, important differences in demographics and etiology exist between countries. Similarly, acute heart failure etiology, severity, and management differ between countries in North America. The overall economic burden of heart failure continues to be large and growing worldwide, with each country managing this burden differently. Understanding the inter-and within-continental differences may help improve understanding of the heart failure epidemic, and may aid healthcare systems in delivering

    This report summarizes die research by an Energy Modeling Forum working group on the evolution of the North American natural gas markets between now and 2010. The group's findings are based partly on the results of a set of economic models of the natural gas industry that were run for four scenarios representing significantly different conditions: two oil price scenarios (upper and lower), a smaller total US resource base (low US resource case), and increased potential gas demand for electric generation (high US demand case). Several issues, such as the direction of regulatory policy and the size of the gas resource base, were analyzed separately without the use of models.

    The Snowbird Roadless Area includes all the upper reaches of Snowbird Creek and the surrounding rugged ridges of the Unicoi Mountains, North Carolina. Mineral-resource surveys show that the area contains folded metasedimentary rocks of the Great Smoky Group of Late Proterozoic age and that the area has little promise for the occurrence of mineral resources. Abundant rock suitable for crushed rock and rough building stone is the only identified mineral resource, but extensive deposits of this commodity occur throughout the region outside the roadless area. Oil and gas and massive sulfide deposits are possible resources.

    2016-01-01

    Accurate expedient species identification of deceased sturgeon (Acipenseridae) when external physical characteristic analysis is inconclusive has become a high priority due to the endangered or threatened status of sturgeon species around the world. Examination of otoliths has provided useful information to aid in population management, age and size-class analysis, understanding predator–prey interactions, and archeological research in other fish species. The relationship between otolith characteristics and sturgeon species has remained unknown. Therefore, we analyzed the shape of otoliths from the eight species of sturgeon found in North America to test the utility of otolith characteristic morphology in species identification. There were distinct differences in the size and shape of the otoliths between species of sturgeon with little shape variation among individuals of the same species. The relationship between otolith length axes was linear, and most of the variability was explained by a Log (axis + 1) transformation of the x and y axes (r2 = 0.8983) using the equation y = 0.73x + 0.0612. Images of otoliths from all eight North American species are presented to assist in the identification process.

  18. SHINING ROCK WILDERNESS, NORTH CAROLINA.

    Lesure, Frank G.; Dunn, Maynard L.

    1984-01-01

    The Shining Rock Wilderness, in the Blue Ridge Mountains of Haywood County, North Carolina, is underlain by complexly folded mica gneiss and schist of Precambrian age. A mineral-resource survey determined that two commodities, quartz as a source of silica (SiO//2) and gneiss and schist suitable for common building stone and crushed rock, are present in large quantities. Demonstrated resources of silica occur at Shining Rock Mountain and small amounts of sheet muscovite (mica) and scrap mica are present at about 10 localities. Until deep drilling is done to test the results of the seismic studies, no estimate of the potential for gas can be made, but the presence of gas cannot be totally discounted.

  19. Pleistocene plants from North Carolina

    Berry, Edward Wilber

    1926-01-01

    The field work upon which this report is based was done in 1906 and 1907 as a part of the cooperative study of the Atlantic Coastal Plain, under the direction of the late William Bullock Clark. Associated with the writer in this work were L. W. Stephenson, B. L. Miller, Jr., and J. E. Pogue. Preliminary accounts of the plants collected were published in 1907 and 1909. As has been frequently emphasized, the study of the Pleistocene floras in this country is in an exceedingly backward state as measured by the volume and precision of our knowledge of Pleistocene floras in Europe. Researches in Pleistocene geology in North America have been confined almost entirely to glaciology, and the problem of the correlation of the glacial deposits with those outside the glaciated area has not been solved, nor is there any general agreement regarding the genesis of the Pleistocene deposits south of the terminal moraines. The present account of what is known of the Pleistocene flora of North Carolina and the conclusions that may be legitimately derived from it is offered in the hope that it may stimulate an interest in a neglected field of research and form a small part of the evidence upon which to base future more comprehensive conclusions and generalizations. A word of explanation regarding the illustrations is required. Nearly all of them have been made from leaves preserved as carbonaceous films in the peaty clays. These specimens were carefully washed out, and blue prints were made directly from them. Outlines and as much of the venation as could be seen were inked on the blue prints, which were then bleached. This procedure made it possible to handle a much larger amount of material and prevented any possible damage to the exceedingly fragile specimens, which were mounted on cards or between glass. The accompanying drawings were made from tracings of the original nature prints.

    According to a 2008 report issued by the United States Geological Survey, North Dakota and Montana have an estimated 3.0 to 4.3 billion barrels of undiscovered, technically recoverable oil in an area known as the Bakken Formation. With the size and remoteness of the discovery, the question became 'can a business case be made for increasing refining capacity in North Dakota?' And, if so what is the impact to existing players in the region. To answer the question, a study committee comprised of leaders in the region's petroleum industry were brought together to define the scope of the study, hire a consulting firm and oversee the study. The study committee met frequently to provide input on the findings and modify the course of the study, as needed. The study concluded that the Petroleum Area Defense District II (PADD II) has an oversupply of gasoline. With that in mind, a niche market, naphtha, was identified. Naphtha is used as a diluent used for pipelining the bitumen (heavy crude) from Canada to crude markets. The study predicted there will continue to be an increase in the demand for naphtha through 2030. The study estimated the optimal configuration for the refinery at 34,000 barrels per day (BPD) producing 15,000 BPD of naphtha and a 52 percent refinery charge for jet and diesel yield. The financial modeling assumed the sponsor of a refinery would invest its own capital to pay for construction costs. With this assumption, the internal rate of return is 9.2 percent which is not sufficient to attract traditional investment given the risk factor of the project. With that in mind, those interested in pursuing this niche market will need to identify incentives to improve the rate of return.

  18. Geologic Framework, Age, and Lithologic Characteristics of the North Park Formation in North Park, North-Central Colorado

    USGS Publications Warehouse

    Shroba, Ralph R.

    2016-10-18

    Deposits of the North Park Formation of late Oligocene and Miocene age are locally exposed at small, widely spaced outcrops along the margins of the roughly northwest-trending North Park syncline in the southern part of North Park, a large intermontane topographic basin in Jackson County in north-central Colorado. These outcrops suggest that rocks and sediments of the North Park Formation consist chiefly of poorly consolidated sand, weakly cemented sandstone, and pebbly sandstone; subordinate amounts of pebble conglomerate; minor amounts of cobbly pebble gravel, siltstone, and sandy limestone; and rare beds of cobble conglomerate and altered tuff. These deposits partly filled North Park as well as a few small nearby valleys and half grabens. In North Park, deposits of the North Park Formation probably once formed a broad and relatively thick sedimentary apron composed chiefly of alluvial slope deposits (mostly sheetwash and stream-channel alluvium) that extended, over a distance of at least 150 kilometers (km), northwestward from the Never Summer Mountains and northward from the Rabbit Ears Range across North Park and extended farther northwestward into the valley of the North Platte River slightly north of the Colorado-Wyoming border. The maximum preserved thickness of the formation in North Park is about 550 meters near the southeastern end of the North Park syncline.The deposition of the North Park Formation was coeval in part with local volcanism, extensional faulting, development of half grabens, and deposition of the Browns Park Formation and Troublesome Formation and was accompanied by post-Laramide regional epeirogenic uplift. Regional deposition of extensive eolian sand sheets and loess deposits, coeval with the deposition of the North Park Formation, suggests that semiarid climatic conditions prevailed during the deposition of the North Park Formation during the late Oligocene and Miocene.The North Park Formation locally contains a 28.1-mega-annum (Ma

  7. Integrative oncology in North America.

    PubMed

    Sagar, Stephen M

    2006-01-01

    Integrative oncology is an evolving evidence-based specialty that uses complementary therapies in concert with medical treatment to enhance its efficacy, improve symptom control, alleviate patient distress and reduce suffering. In North America the evolution of research into complementary therapies was delayed by the narrow focus of the Flexner Report. A government-funded research agenda and incorporation of complementary therapies into medical school curricula have been driven by early evidence of efficacy and patient demand. Integrative oncology focuses on the role of natural health products (botanicals, vitamins, and minerals), nutrition, acupuncture, meditation and other mind-body approaches, music therapy, touch therapies, fitness therapies, and more. Some natural health products, such as herbs and their constituent phytochemicals, may be biologic response modifiers that could increase cancer control. Current research stretches from the laboratory to health services. Institutions are exploring the effectiveness gap in their clinical services and are determining efficacy of complementary therapies through randomized controlled trials. Eventually, the goal is to establish practice guidelines through determining relative effectiveness and value through cost-utility studies. The aim of integrative oncology should be one medicine, not alternative; it should be patient-focused; it should be evidence-based; and it should provide the best care for cancer cure, prevention, symptom control, and quality of life.

  8. North American tidal power prospects

    NASA Astrophysics Data System (ADS)

    Wayne, W. W., Jr.

    1981-07-01

    Prospects for North American tidal power electrical generation are reviewed. Studies by the US Army Corps of Engineers of 90 possible generation schemes in Cobscook Bay, ME, indicated that maximum power generation rather than dependable capacity was the most economic method. Construction cost estimates for 15 MW bulb units in a single effect mode from basin to the sea are provided; five projects were considered ranging from 110-160 MW. Additional tidal power installations are examined for: Half-Moon Cove, ME (12 MW, 18 ft tide); Cook Inlet, AK, which is shown to pose severe environmental and engineering problems due to fish migration, earthquake hazards, and 300 ft deep silt deposits; and the Bay of Fundy, Canada. This last has a 17.8 MW plant under construction in a 29 ft maximum tide area. Other tidal projects of the Maritime Provinces are reviewed, and it is noted that previous economic evaluations based on an oil price of $16/barrel are in need of revision.

    USGS Publications Warehouse

    : Green, David M.; Weir, Linda A.; Casper, Gary S.; Lannoo, Michael

    2014-01-01

    Some 300 species of amphibians inhabit North America. The past two decades have seen an enormous growth in interest about amphibians and an increased intensity of scientific research into their fascinating biology and continent-wide distribution. This atlas presents the spectacular diversity of North American amphibians in a geographic context. It covers all formally recognized amphibian species found in the United States and Canada, many of which are endangered or threatened with extinction. Illustrated with maps and photos, the species accounts provide current information about distribution, habitat, and conservation. Researchers, professional herpetologists, and anyone intrigued by amphibians will value North American Amphibians as a guide and reference.

  14. C : N : P stoichiometry at the Bermuda Atlantic Time-series Study station in the North Atlantic Ocean

    NASA Astrophysics Data System (ADS)

    Singh, A.; Baer, S. E.; Riebesell, U.; Martiny, A. C.; Lomas, M. W.

    2015-11-01

    Nitrogen (N) and phosphorus (P) availability, in addition to other macro- and micronutrients, determine the strength of the ocean's carbon (C) uptake, and variation in the N : P ratio of inorganic nutrient pools is key to phytoplankton growth. A similarity between C : N : P ratios in the plankton biomass and deep-water nutrients was observed by Alfred C. Redfield around 80 years ago and suggested that biological processes in the surface ocean controlled deep-ocean chemistry. Recent studies have emphasized the role of inorganic N : P ratios in governing biogeochemical processes, particularly the C : N : P ratio in suspended particulate organic matter (POM), with somewhat less attention given to exported POM and dissolved organic matter (DOM). Herein, we extend the discussion on ecosystem C : N : P stoichiometry but also examine temporal variation in stoichiometric relationships. We have analyzed elemental stoichiometry in the suspended POM and total (POM + DOM) organic-matter (TOM) pools in the upper 100 m and in the exported POM and subeuphotic zone (100-500 m) inorganic nutrient pools from the monthly data collected at the Bermuda Atlantic Time-series Study (BATS) site located in the western part of the North Atlantic Ocean. C : N and N : P ratios in TOM were at least twice those in the POM, while C : P ratios were up to 5 times higher in TOM compared to those in the POM. Observed C : N ratios in suspended POM were approximately equal to the canonical Redfield ratio (C : N : P = 106 : 16 : 1), while N : P and C : P ratios in the same pool were more than twice the Redfield ratio. Average N : P ratios in the subsurface inorganic nutrient pool were ~ 26 : 1, squarely between the suspended POM ratio and the Redfield ratio. We have further linked variation in elemental stoichiometry to that of phytoplankton cell abundance observed at the BATS site. Findings from this study suggest that elemental ratios vary with depth in the euphotic zone, mainly due to different

    The crisis involving North Korea`s suspected nuclear weapon program is over, at least for now. Pyongyang has agreed to suspend its decision to withdraw from the nuclear Non-Proliferation Treaty (NPT) and to assume its obligations allowing continued International Atomic Energy Agency (IAEA) inspections of its nuclear facilities, although it has yet to accept IAEA {open_quotes}special{close_quotes} inspections of suspect nuclear sites. In exchange, North Korea obtained a few specific commitments from the United States - nuclear non-aggression, for example - as well as hints of longer-term benefits such as high-level US-North Korean talks extending to other topics, the cancellation of the US-South Korean {open_quotes}Team Spirit{close_quotes} military exercise, the right to reciprocal inspections in South Korea and an influx of South Korean and Japanese investment, provided North Korea meets its obligations under the NPT.

    2013-03-01

    Here is a postmodern astro-theological response to factual evidence supporting cometary panspermia, including evidence of cyanobacteria fossils in meteorites (Hoover 2011) and diatom frustules in the Polonnaruwa meteorite (Wickramasinghe and others 2013). Distinct from William Derham's modern astro-theology, and in accordance with John Wesley's avoidance of factual demonstrations/proofs and Wesley's appreciation of factual exemplifications, postmodern astro-theology appreciates cometary panspermia. Cometary panspermia is a specific-factually correct example of panspermia in general. Generic panspermia is essential to panentheism. Cometary panspermia enriches evolutionary biology.

    West Nile virus, a mosquito-vectored flavivirus of the Japanese encephalitis serogroup, was first detected in North America following an epizootic in the New York City area in 1999. In the intervening 11 years since the arrival of the virus in North America, it has crossed the contiguous USA, entered the Canadian provinces bordering the USA, and has been reported in the Caribbean islands, Mexico, Central America and, more recently, South America. West Nile virus has been reported in over 300 species of birds in the USA and has caused the deaths of thousands of birds, local population declines of some avian species, the clinical illness and deaths of thousands of domestic horses, and the clinical disease in over 30 000 Americans and the deaths of over 1000. Prior to the emergence of West Nile virus in North America, St. Louis encephalitis virus and Dengue virus were the only other known mosquito-transmitted flaviviruses in North America capable of causing human disease. This review will discuss the North American experience with mosquito-borne flavivirus prior to the arrival of West Nile virus, the entry and spread of West Nile virus in North America, effects on wild bird populations, genetic changes in the virus, and the current state of West Nile virus transmission.

    1998-01-01

    Nearly all North American heron populations are migratory, but details of where they winter are little known. Locations where North American herons winter were identified using banding recovery data. North American herons winter from Canada through northern South America but especially in eastern North America south of New York, Florida, California, Louisiana, Texas, Mexico and Cuba, these areas accounting for 63% of winter recoveries. We identified regions where recoveries for various species clustered as "key areas." These forty-three areas constitute a network of areas that hold sites that likely are important to wintering North American herons. Within each area, we identify specific sites that are potentially important to wintering herons. The relative importance of each area and site within the network must be evaluated by further on the ground inventory. Because of biases inherent in the available data, these hypothesized key areas are indicative rather than exhaustive. As a first cut, this network of areas can serve to inform further inventory activities and can provide an initial basis to begin planning for the year-round conservation of North American heron populations.

Currently, the detection of ambient biological materials in real-time is mainly based on the presence of fluorophores in the particles. In this study, we present the wideband integrated bioaerosol spectrometer (WIBS) measurement results to characterize the fluorescent aerosol particles (FAP) at a polluted regional site (Xianghe, 39.80 °N, 116.96 °E) in the North China Plain. We observed substantially much higher number concentration of FAP as compared with those of previous studies in clean environments. We found the good agreement between the FAP number fraction in coarse mode particles (> 1 mm) and BC mass fraction in fine particles (< 1 mm), possibly indicating a majority of the observed FAP is to a certain extent related to the anthropogenic burning activities nearby. This interference and uncertainty should be especially noticed when performing fluorescence measurements in the polluted area, where the certain non-biological compounds (such as SOA, PAH and soot) may significantly lead to a positive fluorescence measurement artifacts and an overestimation of actual fluorescent biological aerosol particles.

    Magoon, L.B.; Lillis, P.G.; Bird, K.J.; Lampe, C.; Peters, K.E.

    2003-01-01

    Six North Slope petroleum systems are identified, described, and mapped using oil-to-oil and oil-to-source rock correlations, pods of active source rock, and overburden rock packages. To map these systems, we assumed that: a) petroleum source rocks contain 3.2 wt. % organic carbon (TOC); b) immature oil-prone source rocks have hydrogen indices (HI) >300 (mg HC/gm TOC); c) the top and bottom of the petroleum (oil plus gas) window occur at vitrinite reflectance values of 0.6 and 1.0% Ro, respectively; and d) most hydrocarbons are expelled within the petroleum window. The six petroleum systems we have identified and mapped are: a) a southern system involving the Kuna-Lisburne source rock unit that was active during the Late Jurassic and Early Cretaceous; b) two western systems involving source rock in the Kingak-Blankenship, and GRZ-lower Torok source rock units that were active during the Albian; and c) three eastern systems involving the Shublik-Otuk, Hue Shale and Canning source rock units that were active during the Cenozoic. The GRZ-lower Torok in the west is correlative with the Hue Shale to the east. Four overburden rock packages controlled the time of expulsion and gross geometry of migration paths: a) a southern package of Early Cretaceous and older rocks structurally-thickened by early Brooks Range thrusting; b) a western package of Early Cretaceous rocks that filled the western part of the foreland basin; c) an eastern package of Late Cretaceous and Paleogene rocks that filled the eastern part of the foreland basin; and d) an offshore deltaic package of Neogene rocks deposited by the Colville, Canning, and Mackenzie rivers. This petroleum system poster is part of a series of Northern Alaska posters on modeling. The poster in this session by Saltus and Bird present gridded maps for the greater Northern Alaskan onshore and offshore that are used in the 3D modeling poster by Lampe and others.

    Ground-based measurements strongly support the hypothesis that pollutant materials of anthropogenic origin are being transported over long distances in the midtroposphere and are a significant source of acid rain, acid snow, trace metal deposition, ozone and visibility-reducing aerosols in remote oceanic and polar regions of the Norhern Hemisphere. Atmospheric sulphur budget calculations and studies of acid rain on Bermuda indicate that a large fraction of pollutant materials emitted into the atmosphere in eastern North America are advected eastwards over the North Atlantic Ocean. The first direct airborne measurements of the vertical distribution of tropospheric aerosols over the western North Atlantic is reported here. A newly developed airborne differential adsorption lidar system was used to obtain continuous, remotely sensed aerosol distributions along its flight path. The data document two episodes of long-distance transport of pollutant materials from North America over the North Atlantic Ocean.

  6. The thrust belts of Western North America

    SciTech Connect

    Moulton, F.C.

    1993-08-01

    Most of the Basin and Range physiographic province of western North America is now believed to be part of the overthrust. The more obvious overthrust belt along the eastern edge of the Basin and Range Province is named the Sevier orogenic belt, where older rocks are observed thrust onto younger rocks. More detailed surface geological mapping, plus deep multiple-fold geophysical work and many oil and gas wildcat wells, have confirmed an east-vergent shortened and stacked sequence is present in many places in the Basin and Range. This western compressive deformed area in east central Nevada is now named the Elko orogenic belt by the U.S. Geological Survey. This older compressed Elko orogenic belt started forming approximately 250 m.y. ago when the North American plate started to move west as the Pangaea supercontinent started to fragment. The North American plate moved west under the sediments of the Miogeocline that were also moving west. Surface-formed highlands and oceanic island arcs on the west edge of the North American plate restricted the westward movement of the sediments in the Miogeocline, causing east-vergent ramp thrusts to form above the westward-moving North American plate. The flat, eastward-up-cutting thrust assemblages moved on the detachment surfaces.

  7. Seasonal predictability of the North Atlantic Oscillation

    NASA Astrophysics Data System (ADS)

    Vellinga, Michael; Scaife, Adam

    2015-04-01

    Until recently, long-range forecast systems showed only modest levels of skill in predicting surface winter climate around the Atlantic Basin and associated fluctuations in the North Atlantic Oscillation at seasonal lead times. Here we use a new forecast system to assess seasonal predictability of winter North Atlantic climate. We demonstrate that key aspects of European and North American winter climate and the surface North Atlantic Oscillation are highly predictable months ahead. We demonstrate high levels of prediction skill in retrospective forecasts of the surface North Atlantic Oscillation, winter storminess, near-surface temperature, and wind speed, all of which have high value for planning and adaptation to extreme winter conditions. Analysis of forecast ensembles suggests that while useful levels of seasonal forecast skill have now been achieved, key sources of predictability are still only partially represented and there is further untapped predictability.

  8. Standardized North American marsh bird monitoring protocol

    USGS Publications Warehouse

    Conway, Courtney J.

    2011-01-01

    Little is known about the population status of many marsh-dependent birds in North America but recent efforts have focused on collecting more reliable information and estimates of population trends. As part of that effort, a standardized survey protocol was developed in 1999 that provided guidance for conducting marsh bird surveys throughout North America such that data would be consistent among locations. The original survey protocol has been revised to provide greater clarification on many issues as the number of individuals using the protocol has grown. The Standardized North American Marsh Bird Monitoring Protocol instructs surveyors to conduct an initial 5-minute passive point-count survey followed by a series of 1-minute segments during which marsh bird calls are broadcast into the marsh following a standardized approach. Surveyors are instructed to record each individual bird from the suite of 26 focal species that are present in their local area on separate lines of a datasheet and estimate the distance to each bird. Also, surveyors are required to record whether each individual bird was detected within each 1-minute subsegment of the survey. These data allow analysts to use several different approaches for estimating detection probability. The Standardized North American Marsh Bird Monitoring Protocol provides detailed instructions that explain the field methods used to monitor marsh birds in North America.

  10. Forging the bonds of sympathy: Spirituality, individualism and empiricism in the ecological thought of Liberty Hyde Bailey and its implications for environmental education

    NASA Astrophysics Data System (ADS)

    Azelvandre, John Paul

    Through an examination of the life and work of Liberty Hyde Bailey, this study examines the possibility of an alternate ontological and epistemological foundation for environmental ethics and education that can adequately address the twin concerns of the status of the individual and of the social or biological whole of which the individual is a part. The thesis presented in this study is that a holistic approach that is conceived in terms of monistic idealism will not serve as well as a pluralistic approach that recognizes distinct individuals causally interconnected to form an ecological whole. The term "spirituality" is proposed as indicative of the mode of connection between individuals and wholes conceived in a pluralistic rather than monistic sense. Beginning with a critique of modern environmental philosophy as primarily oriented toward a holistic or monistic ontology, the study proceeds to an intellectual biography of Liberty Hyde Bailey (1858--1954), an important early thinker in environmental ethics and environmental education. The analysis of Bailey's life and work reveals his indebtedness both to Darwinian science, to certain strands of eighteenth century thought passed on through the agency of Freemasonry and to the liberal Protestant Christianity of the late 19th century. His mature philosophy was strongly individualistic, empirical and spiritual, where the "spiritual" is the mode of connection between self and other. Positive connections are drawn between Bailey's contemporaries John Dewey and Alfred North Whitehead, bolstering claims that the distinctly American philosophy exhibited by all three thinkers has important ramifications for environmental philosophy today. Recommendations for environmental ethics and environmental education for the twenty-first century conclude the study.

  11. Earthquakes at North Atlantic passive margins

    Gregersen, S. ); Basham, P.W. )

    1989-01-01

    The main focus of this volume is the earthquakes that occur at and near the continental margins on both sides of the North Atlantic. The book, which contains the proceedings of the NATO workshop on Causes and Effects of Earthquakes at Passive Margins and in Areas of Postglacial Rebound on Both Sides of the North Atlantic, draws together the fields of geophysics, geology and geodesy to address the stress and strain in the Earth's crust. The resulting earthquakes produced on ancient geological fault zones and the associated seismic hazards these pose to man are also addressed. Postglacial rebound in North America and Fennoscandia is a minor source of earthquakes today, during the interglacial period, but evidence is presented to suggest that the ice sheets suppressed earthquake strain while they were in place, and released this strain as a pulse of significant earthquakes after the ice melted about 9000 years ago.

    Petroleum geology and related areas of study at the University of North Dakota (UND) received a huge financial boost with the announcement on 24 September of $14 million in private and public partnership funding. The university announced the naming of the Harold Hamm School of Geology and Geological Engineering, formerly a department within the College of Engineering and Mines, in recognition of $10 million provided as a gift by oilman Harold Hamm and Continental Resources, Inc. Hamm is the chair and chief executive officer of Continental, the largest leaseholder in the Bakken Play oil formation in North Dakota and Montana, and he is also an energy policy advisor to Republican presidential candidate Mitt Romney. UND also received $4 million from the Oil and Gas Research Program of the North Dakota Industrial Commission to support geology and geological engineering education and research.

  13. Ammonia downstream from HH 80 North

    HH 80-81 are two optically visible Herbig-Haro (HH) objects located about 5 minutes south of their exciting source IRAS 18162-2048. Displaced symmetrically to the north of this luminous IRAS source, a possible HH counterpart was recently detected as a radio continuum source with the very large array (VLA). This radio source, HH 80 North, has been proposed to be a member of the Herbig-Haro class since its centimeter flux density, angular size, spectral index, and morphology are all similar to those of HH 80. However, no object has been detected at optical wavelengths at the position of HH 80 North, possibly because of high extinction, and the confirmation of the radio continuum source as an HH object has not been possible. In the prototypical Herbig-Haro objects HH 1 and 2, ammonia emission has been detected downstream of the flow in both objects. This detection has been intepreted as a result of an enhancement in the ammonia emission produced by the radiation field of the shock associated with the HH object. In this Letter we report the detection of the (1,1) and (2,2) inversion transitions of ammonia downstream HH 80 North. This detection gives strong suppport to the interpretation of HH 80 North as a heavily obscured HH object. In addition, we suggest that ammonia emission may be a tracer of embedded Herbig-Haro objects in other regions of star formation. A 60 micrometer IRAS source could be associated with HH 80 North and with the ammonia condensation. A tentative explanation for the far-infrared emission as arising in dust heated by their optical and UV radiation of the HH object is presented.

  14. North American drought: Reconstructions, causes, and consequences

    NASA Astrophysics Data System (ADS)

    Cook, Edward R.; Seager, Richard; Cane, Mark A.; Stahle, David W.

    2007-03-01

    Severe drought is the greatest recurring natural disaster to strike North America. A remarkable network of centuries-long annual tree-ring chronologies has now allowed for the reconstruction of past drought over North America covering the past 1000 or more years in most regions. These reconstructions reveal the occurrence of past "megadroughts" of unprecedented severity and duration, ones that have never been experienced by modern societies in North America. There is strong archaeological evidence for the destabilizing influence of these past droughts on advanced agricultural societies, examples that should resonate today given the increasing vulnerability of modern water-based systems to relatively short-term droughts. Understanding how these megadroughts develop and persist is a timely scientific problem. Very recently, climate models have succeeded in simulating all of the major droughts over North America from the Civil War to the severe 1998-2004 drought in the western U.S. These numerical experiments indicate the dominating importance of tropical Pacific Ocean sea surface temperatures (SSTs) in determining how much precipitation falls over large parts of North America. Of central importance to drought formation is the development of cool "La Niña-like" SSTs in the eastern tropical Pacific region. This development appears to be partially linked to changes in radiative forcing over that region, which affects the Bjerknes feedback mechanism of the ENSO cycle there. Paradoxically, warmer conditions over the tropical Pacific region lead to the development of cool La Niña-like SSTs there, which is drought inducing over North America. Whether or not this process will lead to a greater prevalence of drought in the future as the world warms due to accumulating greenhouse gases is unclear at this time.

  15. The carbon balance of North American wetlands

    Bridgham, S.D.; Megonigal, J.P.; Keller, J.K.; Bliss, N.B.; Trettin, C.

    2006-01-01

    We examine the carbon balance of North American wetlands by reviewing and synthesizing the published literature and soil databases. North American wetlands contain about 220 Pg C, most of which is in peat. They are a small to moderate carbon sink of about 49 Tg C yr-1, although the uncertainty around this estimate is greater than 100%, with the largest unknown being the role of carbon sequestration by sedimentation in freshwater mineral-soil wetlands. We estimate that North American wetlands emit 9 Tg methane (CH 4) yr-1; however, the uncertainty of this estimate is also greater than 100%. With the exception of estuarine wetlands, CH4 emissions from wetlands may largely offset any positive benefits of carbon sequestration in soils and plants in terms of climate forcing. Historically, the destruction of wetlands through land-use changes has had the largest effects on the carbon fluxes and consequent radiative forcing of North American wetlands. The primary effects have been a reduction in their ability to sequester carbon (a small to moderate increase in radiative forcing), oxidation of their soil carbon reserves upon drainage (a small increase in radiative forcing), and reduction in CH4 emissions (a small to large decrease in radiative forcing). It is uncertain how global changes will affect the carbon pools and fluxes of North American wetlands. We will not be able to predict accurately the role of wetlands as potential positive or negative feedbacks to anthropogenic global change without knowing the integrative effects of changes in temperature, precipitation, atmospheric carbon dioxide concentrations, and atmospheric deposition of nitrogen and sulfur on the carbon balance of North American wetlands. 

  16. Composition of the ancient north american crust.

    PubMed

    Condie, K C

    1967-02-24

    Geochemical studies of Wyoming Precambrian graywackes derived from continental crust older than 3.2 x 10(9) years indicate that their source area was at least as highly differentiated as most younger Precambrian crust. The composition of this early crust (approximately that of calcium-rich granite) is not unlike that of the 2.5 to 3.2 x 10(9) year old North American crust. Limited geochemical data suggest that the composition of North America may not have changed significantly during the last 3.0 to 3.5 x 10(9) years.

    First appearing about 40 million years ago in North America, rhinoceroses diversified into an incredible array of taxa, with a variety of ecologies that don't resemble any of the five living species. They ranged from delicate long-legged dog-sized forms, to huge hippo-like forms that apparently lived in rivers and lakes. Including a complete systematic review, and discussions of biogeography, evolution and paleoecology, this book summarizes our current knowledge of North American rhinos and constitutes the most complete reference available.

    The cause of decadal climate variability over the North Pacific Ocean and North America is investigated by the analysis of data from a multidecadal integration with a state-of-the-art coupled ocean-atmosphere model and observations. About one-third of the low-frequency climate variability in the region of interest can be attributed to a cycle involving unstable air-sea interactions between the subtropical gyre circulation in the North Pacific and the Aleutian low-pressure system. The existence of this cycle provides a basis for long-range climate forecasting over the western United States at decadal time scales. PMID:17793457

    Wallace's 1858 paper 'On the tendency of varieties to depart indefinitely from the original type' is often thought to present a theory of natural selection identical with that of Darwin. Examination of Wallace's argument shows that it is different from Darwin's because Wallace thought that an inferior variety could coexist with a superior variety until environmental deterioration forced the extinction of the inferior one. Other interpretations of Wallace's argument are re-examined in the light of this finding. PMID:16116703

  3. The notion of "double consciousness" in Alfred Binet's psychological experimentalism.

    PubMed

    Foschi, Renato; Cicciola, Elisabetta

    2006-01-01

    Between 1889 and 1892, Binet published two remarkable essays, On Double Consciousness and Les alterations de la personnalité, which marked the end of a period of researches and interests closely linked to the doctrines on hypnosis and hysteria elaborated by the Ecole de la Salpêtrière. Later on, Binet was to abandon the utilization of hypnosis as a technique of experimentation, after he realized that the suggestibility of the "subjects" of these experiences had led to major experimental mistakes. However, during the years of his work at the Salpêtrière, he elaborated the notion of "double consciousness," which can be considered an alternative both to Ribot's idea of dissociation and to Janet's idea of disaggregation. The notion of double consciousness reveals both the originality of Binet's psychology--which was elaborated at the end of the nineteenth century--and its verifiable link to twentieth-century psychology. Unlike Janet, in fact, Binet did not support a theory of psychological deficiency or "misery," or of the retraction of the sphere of consciousness, which a normal capacity for psychological synthesis would oppose. On the contrary, Binet's psychology resulted in a theory stating that the duality of consciousness works in a perfect and autonomous way within the individual and, thanks to hypnosis, can be investigated in a laboratory.

  8. Renewables and restructuring in North Carolina

    SciTech Connect

    1999-07-01

    North Carolina is one of 33 states that are evaluating whether and how to restructure their electric utility industries. In most states where restructuring has either already been passed or is being considered, there has been considerable effort on the part of advocacy organizations to implement new policies to support renewable energy growth. It remains unclear, however, when the North Carolina electric industry will be restructured and whether the state will move ahead on its own or wait for a federal mandate. This paper presents the experience and lessons learned to date from efforts to incorporate renewable energy into the proposed restructured electric market structure in North Carolina. This paper focuses on the work of the North Carolina Solar Energy Association, the state's leading renewable energy advocacy organization. Discussion includes the history and status of renewable energy in the state. The paper outlines and discusses NCSEA's proposed policies for a restructured market. These are: (1) opening the market to retail competition so that customers will have a choice of renewable energy providers, (2) mandating fuel mix and emissions disclosure, (3) creating a renewable portfolio standard of 20% renewables by 2010, and (4) establishing a public benefits fund of 2.5 mills/kWh to support both renewable energy and energy efficiency investments. These policy recommendations are based on the long standing recommendation of NCSEA and the NC Energy Policy Council that the state should receive 20% of its energy from renewables by 2010.

  8. North Polar Water Ice by Weight

    NASA Technical Reports Server (NTRS)

    2003-01-01

    December 8, 2003

    This map shows the percent of water by weight in near-surface materials of Mars' north polar region. It is derived from the gamma ray spectrometer component of the gamma ray spectrometer suite of instruments on NASA's Mars Odyssey spacecraft.

    Significant concentrations of water (greater than 20 percent) are poleward of 55 degrees north latitude. The highest concentration, greater than 50 percent, is between 75 degrees north and the pole. Another area with a high concentration of water by weight is in the north polar plains between longitudes minus 105 degrees and minus 140 degrees, and between latitudes 60 degrees and 75 degrees.

    NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the 2001 Mars Odyssey mission for the NASA Office of Space Science in Washington. Investigators at Arizona State University in Tempe, the University of Arizona in Tucson and NASA's Johnson Space Center, Houston, operate the science instruments. The gamma-ray spectrometer was provided by the University of Arizona in collaboration with the Russian Aviation and Space Agency, which provided the high-energy neutron detector, and the Los Alamos National Laboratories, New Mexico, which provided the neutron spectrometer. Lockheed Martin Space Systems, Denver, is the prime contractor for the project, and developed and built the orbiter. Mission operations are conducted jointly from Lockheed Martin and from JPL.

  12. North Atlantic westerlies during the last millennium

    Understanding North Atlantic decadal-scale climate variability is crucial in order to make projections of future climate change and to assess anthropogenic impacts on climate. However, reconstructing past changes in atmospheric circulation patterns from proxy data is particularly challenging, and different proxy reconstructions often show conflicting results. Winter accumulation dominates the annual mass-balance of glaciers along the west coast of Norway, and because the winter accumulation is highly sensitive to changes in the strength of wintertime westerly winds, these glaciers are potentially valuable recorders of past atmospheric circulation. Here we present a 1200-year long spatiotemporal reconstruction of Nordfonna, a maritime plateau glacier in western Norway, based on an integrated study of terrestrial moraine sequences, sub-glacial topography, and multi-proxy records from two distal glacier-fed lakes located at the opposite sides of the glacier in a west-east transect. We use temporal changes in the west-to-east tilt of the Equilibrium-Line-Altitude (ELA) across the ice cap to infer the strength of North-Atlantic westerly winds over the past 1200 years, and validate our high-resolution (5-yr) record against instrumental data. While multidecadal fluctuations in the regional ELA can be explained largely by changes in North Atlantic sea surface temperatures (i.e. the AMO), our data suggests that the local 'Little Ice Age' maximum glacier expansion (AD 1700-1750) was caused mainly by strengthened wintertime westerlies. The wintertime westerlies over southern Norway are closely linked to the leading mode of atmospheric variability in the North Atlantic, known as the North Atlantic Oscillation (NAO), and our record therefore represents a unique proxy of past changes in the NAO.

  13. Martian north polar cap summer water cycle

    NASA Astrophysics Data System (ADS)

    Brown, Adrian J.; Calvin, Wendy M.; Becerra, Patricio; Byrne, Shane

    2016-10-01

    A key outstanding question in Martian science is "are the polar caps gaining or losing mass and what are the implications for past, current and future climate?" To address this question, we use observations from the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) of the north polar cap during late summer for multiple Martian years, to monitor the summertime water cycle in order to place quantitative limits on the amount of water ice deposited and sublimed in late summer. We establish here for the first time the summer cycle of water ice absorption band signatures on the north polar cap. We show that in a key region in the interior of the north polar cap, the absorption band depths grow until Ls = 120, when they begin to shrink, until they are obscured at the end of summer by the north polar hood. This behavior is transferable over the entire north polar cap, where in late summer regions 'flip' from being net sublimating into net condensation mode. This transition or 'mode flip' happens earlier for regions closer to the pole, and later for regions close to the periphery of the cap. The observations and calculations presented herein estimate that on average a water ice layer ∼70 microns thick is deposited during the Ls = 135-164 period. This is far larger than the results of deposition on the south pole during summer, where an average layer 0.6-6 microns deep has been estimated by Brown et al. (2014) Earth Planet. Sci. Lett., 406, 102-109.

    Background Putative phytogeographical links between America (especially North America) and the Hawaiian Islands have figured prominently in disagreement and debate about the origin of Pacific floras and the efficacy of long-distance (oversea) plant dispersal, given the obstacles to explaining such major disjunctions by vicariance. Scope Review of past efforts, and of progress over the last 20 years, toward understanding relationships of Hawaiian angiosperms allows for a historically informed re-evaluation of the American (New World) contribution to Hawaiian diversity and evolutionary activity of American lineages in an insular setting. Conclusions Temperate and boreal North America is a much more important source of Hawaiian flora than suggested by most 20th century authorities on Pacific plant life, such as Fosberg and Skottsberg. Early views of evolution as too slow to account for divergence of highly distinctive endemics within the Hawaiian geological time frame evidently impeded biogeographical understanding, as did lack of appreciation for the importance of rare, often biotically mediated dispersal events and ecological opportunity in island ecosystems. Molecular phylogenetic evidence for North American ancestry of Hawaiian plant radiations, such as the silversword alliance, mints, sanicles, violets, schiedeas and spurges, underlines the potential of long-distance dispersal to shape floras, in accordance with hypotheses championed by Carlquist. Characteristics important to colonization of the islands, such as dispersibility by birds and ancestral hybridization or polyploidy, and ecological opportunities associated with ‘sky islands’ of temperate or boreal climate in the tropical Hawaiian archipelago may have been key to extensive diversification of endemic lineages of North American origin that are among the most species-rich clades of Hawaiian plants. Evident youth of flowering-plant lineages from North America is highly consistent with recent geological

  15. Sedimentology of the Nanushuk Group, North Slope

    Huffman, A.C. Jr.; Ahlbrandt, T.S.; Bartsch-Winkler, S.

    1989-01-01

    The Nanushuk Group of Albian and Cenomanian age is a regressive sequence of marine, transitional, and nonmarine deposits exposed in an outcrop belt 30 to 50 km wide and approximately 650 km long in the Arctic foothills province, North Slope, Alaska. Sedimentary rocks of the Nanushuk Group constitute a potentially major hydrocarbon source within the National petroleum Reserve in Alaska (NPRA). The most significant known oil field within the NPRA is in the Nanushuk Group at Umiat anticline and has been estimated to contain as much as 122 million barrels of oil. Previous outcrop and subsurface studies established the regional nature and extent of the Nanushuk Group. Most of these studies can be grouped by geographic areas into those dealing primarily with the (1) southwestern North Slope; (2) south-central North Slope; (3) eastern North Slope; (4) subsurface of northwestern and northcentral North Slope. More recent work, undertaken as a part of the NPRA exploration program, concentrated on a regional synthesis of various aspect of the geology of the Nanushuk Group. Recent sedimentologic studies of the Nanushuk Group have been employed a genetic-stratigraphy approach in order to avoid the confusion surrounding the nomenclature and arrive at a better understanding of the systems responsible for the deposition of the Nanushuk. The currently accepted stratigraphic nomenclature for the Nanushuk Group and related rocks is shown in figure 13.2; however, very few stratigraphic names below group rank are used in the following discussion. Terminology employed in any discussion of depositional environments is determined to a large extent by the depositional model being used. Depositional models currently applied to the Nanushuk Group together with their terminology are described below.

  16. Decadal climate variability over the North Pacific and North America: Dynamics and predictability

    SciTech Connect

    Latif, M.; Barnett, T.P.

    1996-10-01

    The dynamics and predictability of decadal climate variability over the North Pacific and North America are investigated by analyzing various observation datasets and the output of a state of the art coupled ocean-atmosphere general circulation model that was integrated for 125 years. Both the observations and model results support the picture that the decadal variability in the regional of interest is based on a cycle involving unstable ocean-atmosphere interactions over the North Pacific. The period of this cycle is of the order of a few decades. The cycle involves the two major circulation regimes in the North Pacific climate system, the subtropical ocean gyre, and the Aleutian low. 41 refs., 18 figs.

    The discovery of the Pliocene red panda ( Parailurus) in the West Transbaikal area, as well as Asian raccoons in North Eurasia and North America, indicates that forested areas with bamboo bushes were wide-spread in the Holarctic during the Neogene. During the Late Pliocene, due to a gradual cooling of the climate, altiplanation, and other factors, their habitat started disintegrating, and red pandas began dying out, surviving only in China.
