    Howard, Daniel R; Mason, Andrew C; Hill, Peggy S M

    2008-11-01

    The prairie mole cricket (Gryllotalpa major Saussure) is a rare orthopteran insect of the tallgrass prairie ecosystem of the south central USA. Populations are known to currently occupy fragmented prairie sites in Oklahoma, Arkansas, Kansas and Missouri, including The Nature Conservancy's Tallgrass Prairie Preserve in north central Oklahoma. Prairie mole cricket populations were surveyed at this site and at another site in Craig County, OK during the spring of 2005 and 2006, using the male cricket's acoustic call to locate advertising aggregations of males. Five males from one large aggregation were removed in a study to describe (1) the hearing thresholds across the call's range of frequencies, (2) the distances over which the higher harmonic components of the male's calls are potentially detectable, (3) the species' sensitivity to ultrasound and (4) the spatio-auditory dynamics of the prairie mole cricket lek. Results indicate that G. major has a bimodal pattern of frequency tuning, with hearing sensitivities greatest at the 2 kHz carrier frequency (41 dB SPL) and declining through the call's frequency range (84 dB at 10 kHz). A second sensitivity peak is evident in the ultrasound range at 25 kHz (62 dB SPL). Spatial analysis of G. major lek sites indicates that approximately 73% of males within the lek are spaced in such a way as to allow acoustic interaction at the species' carrier frequency, while any information in higher harmonic overtones in the call appears to be available only to nearest neighbors.

  2. Binema bonaerensis n. sp. (Oxyurida: Thelastomatidae) parasite of Neocurtilla claraziana Saussure (Orthoptera: Gryllotalpidae) in Argentina.

    Camino, N B; Reboredo, G R

    1999-01-01

    The nematode Binema bonaerensis n. sp. (Oxyurida: Thelastomatidae) is described from the intestine of the mole cricket of Neocurtilla claraziana Saussure (Orthoptera: Gryllotalpidae) from Buenos Aires Province, Argentina. It is distinguished mainly by having a conical tail; three sclerotized arches in the buccal cavity; an excretory pore immediately posterior to the base of the esophagus and the presence of five pairs of male genital papillae with one pair preanal and four pairs postanal.

  3. The type specimen and generic placement of Tridactylus galla Saussure, 1895 (Orthoptera: Caelifera: Tridactylidae).

    Heads, Sam W; Hollier, John

    2016-11-15

    Tridactylus galla was described by Henri de Saussure (1895) on the basis of a single adult female collected during Vittorio Bottego's first expedition to the Horn of Africa in 1892 and 1893. The species appears in lists compiled by Fenizia (1896), Lucas (1898) and Kirby (1906), but aside from a brief mention by Günther (1995), is entirely overlooked by subsequent authors and is absent from Otte's (1997) catalogue. During the course of compiling an annotated catalogue of the Orthoptera described by Saussure (Hollier and Heads, 2012) we were able to relocate the type of Tridactylus galla in the collection of the Museo Civico di Storia Naturale "Giacomo Doria" in Genova, Italy. Our examination of the specimen confirmed Günther's (1995) assertion that its placement in Tridactylus Olivier, 1789 is erroneous, and the species is herein formally transferred to the genus Xya Latreille, 1809.

    Two new species of the genus Haplotropis Saussure, 1888 from China are described in this paper. The new species Haplotropis xiai sp. nov. is similar to Haplotropis brunneriana Saussure, 1888, but differs from latter by frontal ridge of male widened at median ocellus; tegmina narrower, cover 2/5 tympanum; cercus of male apical half part gently tapering; lower margin of epiphallus with high projection in the middle; anterior margin of pronotum in female with distinct acute angular in middle; length of subgenital plate shorter than width in female. The Haplotropis zhuoluensis sp. nov. is similar to Haplotropis xiai sp. nov., but differs from latter by anterior margin of pronotum reaching hind margin of eyes; length of temina is 1.6 times in male and 1.3 times in female of width; length of interspace shorter than narrowest in mesosternum of male; ancorae of epiphallus oblique inward distinctly, lower margin with high projection in the middle; length of subgenital plate longer than width in female. Type specimens are deposited in the College of Life Sciences, Hebei University, Baoding, China.

  8. Body Size, Fecundity, and Sexual Size Dimorphism in the Neotropical Cricket Macroanaxipha macilenta (Saussure) (Orthoptera: Gryllidae).

    Cueva Del Castillo, R

    2015-04-01

    Body size is directly or indirectly correlated with fitness. Body size, which conveys maximal fitness, often differs between sexes. Sexual size dimorphism (SSD) evolves because body size tends to be related to reproductive success through different pathways in males and females. In general, female insects are larger than males, suggesting that natural selection for high female fecundity could be stronger than sexual selection in males. I assessed the role of body size and fecundity in SSD in the Neotropical cricket Macroanaxipha macilenta (Saussure). This species shows a SSD bias toward males. Females did not present a correlation between number of eggs and body size. Nonetheless, there were fluctuations in the number of eggs carried by females during the sampling period, and the size of females that were collected carrying eggs was larger than that of females collected with no eggs. Since mating induces vitellogenesis in some cricket species, differences in female body size might suggest male mate choice. Sexual selection in the body size of males of M. macilenta may possibly be stronger than the selection of female fecundity. Even so, no mating behavior was observed during the field observations, including audible male calling or courtship songs, yet males may produce ultrasonic calls due to their size. If female body size in M. macilenta is not directly related to fecundity, the lack of a correlated response to selection on female body size could represent an alternate evolutionary pathway in the evolution of body size and SSD in insects.

  9. Revision of the Madagascan genera Oncodopus Brongniart and Colossopus Saussure (Orthoptera: Tettigoniidae: Conocephalinae; Euconchophorini), with description of Malagasopus gen. nov.

    2017-10-31

    The endemic Madagascan genera Oncodopus Brongniart and Colossopus Saussure are revised using museum specimens, including the types, and recently collected material. A new genus, Malagasopus gen. nov., and seven new species, Malagasopus desutterae sp. nov., Malagasopus meridianus sp. nov., Oncodopus janetae sp. nov., Oncodopus brongniarti sp. nov., Oncodopus saussurei sp. nov., Oncodopus soalalaensis sp. nov. and Colossopus parvicavus sp. nov. are described. Lectotypes are designated for Oncodopus zonatus Brongniart, 1897 and Colossopus redtenbacheri (Brongniart, 1897). A new term, mesothoracic auricle, is proposed for a structure on the episternum of the mesothorax. A tabulated key to the genera and keys to the species are presented. All species are described and diagnosed, and their phylogenetic relationships, geographical distributions, habitat preferences and phenologies are documented. The life history of Colossopus grandidieri is described, and the unusual possible mate-guarding behaviour of several species is discussed. Maps showing the distribution of the species are presented, as too are 57 photographs of museum specimens, 51 drawings of morphological characters, 17 photographs of living specimens and one habitat photograph.

  11. SAUSSURE AND THE SYLLABLE

    Ricardo Lopes Leite

    2014-06-01

    Full Text Available Este artigo põe em relevo a noção de sílaba formulada por Saussure, apresentada sistematicamente nos Princípios de Fonologia, capítulo-apêndice do Curso de Linguística Geral. Apesar de pouco citada por aqueles que se dedicam à obra do mestre genebrino, a teorização sobre a sílaba evidencia a originalidade da reflexão saussuriana sobre fonologia. A sílaba é concebida como um princípio geral e, portanto, de natureza abstrata, para a descrição sintagmática das unidades fônicas das línguas, cujo parâmetro de análise é a sonoridade e seus desdobramentos: graus de abertura e fechamento, mecanismos de implosão/explosão e o par funcional soante/consoante. Com isso, quer-se mostrar que a sílaba em Saussure constitui uma categoria teórica, de natureza funcional, que ultrapassa o campo da fonologia para inspirar o pensamento semiolinguístico de muitos dos seguidores de Saussure.

    Full Text Available Ferdinand de Saussure is widely known as one of the prominent contributor to the theories of sign and language in semiotic. His theory in semiotic create a mark in the history of semiology. His semiotic was also known as one of the foundation of structuralism that growth in France. Structuralism, later become a movement that widespread not only in the field of linguistic but to the field of humanities and social sciences in general. How his semiotic works and how his view on structuralism applied in world of sign and language are interesting object. This writing try to overview all this in a simple and understandable way

  17. The complete mitochondrial genome of Gryllotalpa unispina Saussure, 1874 (Orthoptera: Gryllotalpoidea: Gryllotalpidae).

    Zhang, Yulong; Shao, Dandan; Cai, Miao; Yin, Hong; Zhang, Daochuan

    2016-01-01

    The complete mitochondrial genome of Gryllotalpa unispina was 15,513 bp in length and contained 70.9% AT. All G. unispina protein-coding sequences except for the nad2 started with a typical ATN codon. The usual termination codons (TAA) and incomplete stop codons (T) were found from 13 protein-coding genes. All tRNA genes were folded into the typical cloverleaf secondary structure, except trnS(AGN) lacking the dihydrouridine arm. The sizes of the large and small ribosomal RNA genes were 1245 and 725 bp, respectively. The A + T-rich region was 917 bp in length with 76.8%. The orientation and gene order of the G. unispina mitogenome were identical to the G. orientalis and G. pluvialis, there was no phenomenon of "DK rearrangement" which has been widely reported in Caelifera.

  19. Biogeographic patterns and diversification dynamics of the genus Cardiodactylus Saussure (Orthoptera, Grylloidea, Eneopterinae) in Southeast Asia.

    Dong, Jiajia; Kergoat, Gael J; Vicente, Natállia; Rahmadi, Cahyo; Xu, Shengquan; Robillard, Tony

    2018-06-07

    Southeast Asia harbors an extraordinary species richness and endemism. While only covering 4% of the Earth's landmass, this region includes four of the planet's 34 biodiversity hotspots. Its complex geological history generated a megadiverse and highly endemic biota, attracting a lot of attention, especially in the field of island biogeography. Here we used the cricket genus Cardiodactylus as a model system to study biogeographic patterns in Southeast Asia. We carried out molecular analyses to: (1) infer phylogenetic relationships based on five mitochondrial and four nuclear markers, (2) estimate divergence times and infer biogeographical ancestral areas, (3) depict colonization routes, and summarize emigration and immigration events, as well as in situ diversification, and (4) determine whether shifts in species diversification occurred during the course of Cardiodactylus evolution. Our results support the monophyly of the genus and of one of its species groups. Dating and biogeographical analyses suggest that Cardiodactylus originated in the Southwest Pacific during the Middle Eocene. Our reconstructions indicate that Southeast Asia was independently colonized twice during the Early Miocene (ca. 19-16 Million years ago), and once during the Middle Miocene (ca. 13 Million years ago), with New Guinea acting as a corridor allowing westward dispersal through four different passageways: Sulawesi, the Philippines, Java and the Lesser Sunda Islands. Sulawesi also served as a diversification hub for Cardiodactylus through a combination of high immigration and in situ diversification events, which can be accounted for by the complex geological history of the Wallacea region.

  20. Photosynthesis: From De Saussure To Liebig.

    Pennazio, Sergio

    2017-01-01

    The dawn of photosynthesis, characterized by the research of Priestley, Ingen- Housz and Senebier, culminated in 1804 with a historical essay of Théodore De Saussure. According to the historians, during the first half of the nineteenth century in which the genesis of the cell theory started off, the research on photosynthesis met a phase of stagnation. Indeed, the literature review of the period does not report particular innovation; however, several scientists (botanists, physiologists, and chemists) supported the thesis of De Saussure with a series of analyses that, in our opinion, deserve to be known. Mirbel, De Candolle, Raspail, Berzelius, Payen, Dutrochet, von Mohl, and other scholars attempted to expand knowledge on photosynthesis but were not able to arrive at a theory that was consistent with a functional mechanism, nor with a suitable chemical model to explain the transformation of the water and carbon dioxide into sugars. A classic case of such inadequacy concerns the discovery of chlorophyll. This compound, isolated in 1818 by Pelletier and Caventou, remained an enigma for many years and was never put in relation with the synthesis of starch. The accurate research of von Mohl led this scientist to believe that the granules of chlorophyll were entirely independent of starch granules, although in many cases these latter were observable inside the granules of chlorophyll. Only in the early forties, Justus von Liebig realized that the assimilation of carbon and hydrogen required a series of chemical reactions that, starting from some organic acids, ended in the formation of sugar. In conclusion, our analysis does not lead to define this period as stagnation but rather as transition, in which the concept of photosynthesis was clear, even though difficult to treat under physiological and chemical views. From the sixties, the researches of Julius von Sachs will open a new road, thanks also to the research carried out in the transition period. Copyright:

  1. Language and "Psychological Race": Leopold de Saussure on French in Indochina.

    Suggests that certain features of race as defined in the work of Gustave Le Bon and Leopold de Saussure (on the psychology of French colonization) may survive in Ferdinand de Saussure's concept of "langue," adapted and transformed by Saussure's more modernist concept of history. (Author/VWL)

  2. Saussure chiama, pascoli risponde. Nuove prospettive sulla ricerca anagrammatica

    Giovanni Palmieri

    2016-07-01

    Full Text Available Dopo un’ampia e aggiornata ricostruzione storico-filologica della corrispondenza tra Saussure e Pascoli, l’articolo suggerisce nuove prospettive sulla ricerca ana-grammatica negando che esista uno iato insanabile tra il Saussure degli anagrammi e quello del Cours. Per dimostrare ciò, l’autore si avvale anche degli scritti saussuriani ritrovati nel 1996. In particolare, Saussure avrebbe ‘scoperto’ il significante (elemento linguistico individuato in contrapposizione alla figure vocale e le serie paradigmatiche proprio a partire dalla sua ricerca sulle associazioni foniche presenti nelle strutture anagrammatiche del linguaggio (poetico. Inoltre, a partire da una riflessione sul principio di similarità fonica, il confronto tra le due ricerche saussuriane consente di limitare il preteso dogma dell’arbitrarietà del segno. Ciò in perfetto accordo con Jakobson. Sviluppando poi un’intuizione di Meillet, viene analizzato il rapporto che esiste tra anagrammi e musica (dodecafonica, nel caso in questione. Chiude l’articolo una lettera immaginaria, ma non troppo, con la quale Pascoli avrebbe potuto rispondere a Saussure sulla questione degli anagrammi presenti nel testo poetico.

  3. Raymond de Saussure. First president of the European Psychoanalytical Federation.

    Vermorel, H

    1998-02-01

    The author reviews the life and career of the Swiss psychoanalyst Raymond de Saussure, who died in 1971. A member of an ancient Protestant family with a distinguished intellectual record in Geneva, Saussure studied medicine and psychiatry before turning to psychoanalysis after a fateful encounter with Sigmund Freud, with whom he subsequently maintained intermittent contacts. His subsequent efforts to establish psychoanalysis as a discipline in its own right separate from psychiatry, especially in the French-speaking countries, are described in detail. We learn of his important role in the promotion of psychoanalysis, the organisation of psychoanalytic training and the publication of psychoanalytic material, including his own substantial theoretical and clinical contributions. He is shown also to have had a wide range of other interests. Particular stress is laid on Saussure's Europeanism, as revealed in his familiarity with Germanic as well as French-language culture, his activities in France in addition to Switzerland, his role as an ambassador for European culture during his New York period, and, most importantly, his commitment to the formation of the European Psychoanalytical Federation, of which he was the first President. The author notes too that Saussure was a man of unfailing courtesy.

  4. Digestive morphophysiology of Gryllodes sigillatus (Orthoptera: Gryllidae).

    Biagio, Fernanda P; Tamaki, Fabio K; Terra, Walter R; Ribeiro, Alberto F

    2009-12-01

    The evolution of the digestive system in the Order Orthoptera is disclosed from the study of the morphophysiology of the digestive process in its major taxa. This paper deals with a cricket representing the less known suborder Ensifera. Most amylase and trypsin activities occur in crop and caeca, respectively. Maltase and aminopeptidase are found in soluble and membrane-bound forms in caeca, with aminopeptidase also occurring in ventriculus. Amaranth was orally fed to Gryllodes sigillatus adults or injected into their haemolymph. The experiments were performed with starving and feeding insects with identical results. Following feeding of the dye the luminal side of the most anterior ventriculus (and in lesser amounts the midgut caeca) became heavily stained. In injected insects, the haemal side of the most posterior ventriculus was stained. This suggested that the anterior ventriculus is the main site of water absorption (the caeca is a secondary one), whereas the posterior ventriculus secretes water into the gut. Thus, a putative counter-current flux of fluid from posterior to anterior ventriculus may propel digestive enzyme recycling. This was confirmed by the finding that digestive enzymes are excreted at a low rate. The fine structure of midgut caeca and ventriculus cells revealed that they have morphological features that may be related to their involvement in secretion (movement from cell to lumen) and absorption (movement from lumen to cell) of fluids. Furthermore, morphological data showed that both merocrine and apocrine secretory mechanisms occur in midgut cells. The results showed that cricket digestion differs from that in grasshopper in having: (1) more membrane-bound digestive enzymes; (2) protein digestion slightly displaced toward the ventriculus; (3) midgut fluxes, and hence digestive enzyme recycling, in both starved and fed insects.

  5. The sing for Humboldt, for Saussure and for Bakhtin

    Sebastião Elias Milani

    2015-01-01

    Full Text Available This article shows three of the principal sign conceptions of the studies about language, differences and similarities. The sign is for Humboldt the material representation, or sound-image, of the concept, besides the identity of the articulated language sound; these three parts, sign, concept and sound identity, make the form of the language that is the word. The sign is for Saussure the name of the relation between the signified and the signifier. Saussure proposed the substitution of the terms sound-image and concept, that were full of suggestions and prior conceptualization, to the terms signified and signifier. The sign in Bakhtin is the form of the structure that accomplishes an ideologically sense completed by thought through articulated sound. The meeting between the articulated sound and the concept gives the resulting element of semiosis, so every sign is semiotic.

  6. Genetic Variation and Geographic Differentiation Among Populations of the Nonmigratory Agricultural Pest Oedaleus infernalis (Orthoptera: Acridoidea) in China

    2015-01-01

    The nonmigratory grasshopper Oedaleus infernalis Saussure (Orthoptera : Acridoidea) is an agricultural pest to crops and forage grasses over a wide natural geographical distribution in China. The genetic diversity and genetic variation among 10 geographically separated populations of O. infernalis was assessed using polymerase chain reaction-based molecular markers, including the intersimple sequence repeat and mitochondrial cytochrome oxidase sequences. A high level of genetic diversity was detected among these populations from the intersimple sequence repeat (H: 0.2628, I: 0.4129, Hs: 0.2130) and cytochrome oxidase analyses (Hd: 0.653). There was no obvious geographical structure based on an unweighted pair group method analysis and median-joining network. The values of FST, θII, and Gst estimated in this study are low, and the gene flow is high (Nm > 4). Analysis of the molecular variance suggested that most of the genetic variation occurs within populations, whereas only a small variation takes place between populations. No significant correlation was found between the genetic distance and geographical distance. Overall, our results suggest that the geographical distance plays an unimpeded role in the gene flow among O. infernalis populations. PMID:26496789

  9. Signification Beyond Representation: F. De Saussure, J. Baudrillard

    Jovilė Kotryna Barevičiūtė

    2011-04-01

    Full Text Available The article deals with the relationship between signification and representation in the context of social, cultural and philosophical topicalities of today. Sustaining by the differential theory of language of the French structuralist F. de Saussure and by the theory of simulation of the contemporary philosopher of media J. Baudrillard, it is maintained that under the influence of historical transformations of capitalism the sign and the referent sever from each other. Under the influence of changing of the engineering and the order of fabrication, the production is replaced by the reproduction. That is why, according to J. Baudrillard, the overall process of simulation establishes and the post-marxistic political economy constitutes self–defining non–referential system of signification. Sustaining by the semiotics of F. de Saussure, the signs of the social status become autonomic in point of the Real, and they exist only in relation with the other signs in the medium of contemporary simulacrum. That is why the social life can be treated as the fighting for the prestige and status. Under these circumstances the classical principle of representation is displaced by the contemporary principle of simulation.

    The genus Antodynerus de Saussure, 1855 is reviewed from the Indian subcontinent. Three species with one additional subspecies are present, namely Antodynerus flavescens flavescens (Fabricius, 1775), A. f. karachiensis Giordani Soika, 1970, A. limbatus (de Saussure, 1852), and A. punctatipennis (de Saussure, 1853). The parasitic association of strepsipteran insects and the symbiotic association of mites are reported for the first time in the genus Antodynerus. The distribution of A. f. flavescens (Fabricius) and A. limbatus (de Saussure) in the Indian states is augmented. The latter species is newly recorded from China (Tibet). A key to species of the Indian subcontinent is provided.

    Full Text Available The genus Chlamydotheca Saussure, 1858 is a typical representative of the Neotropical ostracod fauna that occupies lotic and lentic environments including temporary and permanent ponds. Up to the present, four species have been recorded in Argentina: C. iheringi (Sars, C. incisa (Claus and C. leuckarti (Claus, and C. symmetrica (Vávra. Temporary and permanent ponds of this region were sampled for ostracods, using a fine mesh net. Three species belonging to the genus Chlamydotheca were collected of which C. arcuata (Sars is recorded for first time for the Chacoan region. Limb morphology was studied under light microscope and line drawings were made using camera lucida. Valves were photographed under scanning electron microscope and redescriptions of C. arcuata and C. iheringi are provided and distributional aspects of the species sampled are discussed.

    The solar collector was invented 200 years before the first oil crisis: in 1774, the geologist and physicist H.B. de Saussure from Geneva built his ''Heliothermometer'' which is amazingly similar to today's solar collectors. With this, he laid the foundation for farming solar energy. 53 figs., 5 tabs., refs.

  15. Acute toxicity of fire-retardant and foam-suppressant chemicals to yalella azteca (Saussure)

    McDonald, Susan F.; Hamilton, Steven J.; Buhl, Kevin J.; Heisinger, James F.

    1997-01-01

    Acute toxicity tests were conducted with Hyalella azteca Saussure (an amphipod) exposed in soft and hard waters to three fire retardants (Fire-Trol GTS-R, Fire-Trol LCG-R, and Phos-Chek D75-F) and two foam suppressants (Phos-Chek WD-881 and Silv-Ex). The chemicals were slightly to moderately toxic to amphipods. The most toxic chemical to amphipods in soft and hard water was Phos-Chek WD-881 (96-h mean lethal concentration [LC50] equal to 10 mg/L and 22 mg/L, respectively), and the least toxic chemical to amphipods in soft water was Fire-Trol GTS-R (96-h LC50 equal to 127 mg/L) and in hard water was Fire-Trol LCG-R (96-h LC50 equal to 535 mg/L). Concentrations of ammonia in tests with the three fire retardants and both water types were greater than reported LC50 values and probably were the major toxic component. Estimated un-ionized ammonia concentrations near the LC50 were frequently less than the reported LC50 ammonia concentrations for amphipods. The three fire retardants were more toxic in soft water than in hard water even though ammonia and un-ionized ammonia concentrations were higher in hard water tests than in soft water tests. The accidental entry of fire-fighting chemicals into aquatic environments could adversely affect aquatic invertebrates, thereby disrupting ecosystem function.

    Xanthopimpla Saussure, 1892 is one of the largest and best studied genera of the family Ichneumonidae. It is most species rich in the Oriental and Afrotropical regions with only a few species occurring in Central and South America. The present study reviews the Neotropical species of the genus including descriptions of four new species from Amazonia and Northeast South America. We define a new species group: the amazonica species-group, to accommodate the following five species: X. amazonica Gómez, Sääksjärvi & Veijalainen, X. guianensis Gómez & Sääksjärvi sp. n., X. jussilai Veijalainen, Sääksjärvi & Broad, X. pucallpensis Gómez & Sääksjärvi sp. n. and X. vidali Gómez sp. n. The aurita species-group, which had hitherto been regarded as the only species-group in the Neotropical region, is currently represented by five species: X. allpahuaya Gómez & Sääksjärvi sp. n., X. aurita Krieger, X. craspedoptera Krieger, X. rhabdomera Townes and X. spiloptera Krieger. The Andean species X. peruana Krieger is established as an unplaced species outside of the amazonica and aurita species-groups. A key to Neotropical species-groups and species of Xanthopimpla is provided. Xanthopimpla aurita is recorded for the first time from Ecuador and Colombia and its extensive distribution is discussed.

Marie de Saussure et organisées, classées et archivées à la Bibliothèque Publique de Genève, par Robert Godel. Cette première conférence, objet de notre intérêt, fait partie d’un ensemble plus important de manuscrits qui ont servi ce notes préparatoires pour les trois premières conférences de Saussure à Genève et marque son retour à la terre natale. Notre analyse se concentre sur les moments d’interruption du lisible provoqués par des hésitations de Saussure lors de l’écriture de son texte et a mis l’enjeu sur la productivité de telles hésitations. Outre cela, cette première conférence mérite notre attention par la façon dont Saussure a cherché à y construire un discours à propos de la linguistique et du rôle du linguiste à partir de la nature de son objet, qui ne lui paraît pas, non plus, éclairée. Notre analyse nous a permis de différencier trois groupes de ratures à partir des thèmes délimités par eux-mêmes. Le thème du premier groupe semble être cher à Saussure: la place des études du langage dans le cadre des sciences humaines ; le thème du deuxième groupe est très cher à linguistique, elle-même : la nature de son objet; dans le troisième groupe on a les questions qui concernent le général et le particulier dans l’approche de l’objet de la linguistique et finalement, on a ce qui semble être demeuré à l’ombre d’une élaboration dans ce manuscrit : la parole. L’analyse de ces trois groupes de ratures, qui gravitent autour de certains thèmes, nous a permis de pointer des moments de tension et/ou d’hésitation lors de l’élaboration des concepts qui devraient encore être définis, plus spécifiquement.

    2014-01-01

    A recent targeted entomological survey in the Republic of Rwanda has produced two conspecific male and female specimens of an undescribed species of praying mantis (Mantodea). The specimens were collected in Nyungwe National Park in May of 2013. The species is closest morphologically to Dystacta alticeps (Schaum, 1853). Therefore, a new species is described, Dystacta tigrifrutex sp. n., along with the first instar nymphs and ootheca. In addition, the previously monotypic genus Dystacta Saussure, 1871 is re-described to provide a broader definition of the genus group. Habitus images, measurement data, a key to species, natural history information, and locality data are provided.

    Full Text Available We report the first record of Megaselia scalaris (Loew infesting laboratory stocks of the praying mantis (Parastagmatoptera tessellata, Saussure. M. scalaris, the scuttle fly, is a cosmopolitan species with a broad niche as it performs as detritivore, facultative parasite, and parasitoid. M. scalaris larvae were found feeding inside adult mantids and, when development was completed, pupae were found inside the abdominal cavity and around the body. We discuss the presence of colonies of crickets bred as prey for the mantids as a facilitator of M. scalaris infestation.

  10. Disentangling the role of management, vegetation structure, and plant quality for Orthoptera in lowland meadows.

    Schirmel, Jens; Gerlach, Rebekka; Buhk, Constanze

    2017-08-17

    Seminatural grasslands provide habitats for various species and are important for biodiversity conservation. The understanding of the diverse responses of species and traits to different grassland management methods is therefore urgently needed. We disentangled the role of grassland management (fertilization and irrigation), vegetation structure (biomass, sward height) and plant quality (protein and fiber content) for Orthoptera communities in lowland hay meadows in Germany. We found vegetation structure to be the most important environmental category in explaining community structure of Orthoptera (species richness, total individuals, functional diversity and species composition). Intensively used meadows (fertilized, irrigated, high plant biomass) were characterized by assemblages with few species, low functional diversity, and low conservation value. Thereby, the relatively moderate fertilizer inputs in our study system of up to ∼75 kg N/ha/year reduced functional diversity of Orthoptera, while this negative effect of fertilization was not detectable when solely considering taxonomic aspects. We found strong support for a prominent role of plant quality in shaping Orthoptera communities and especially the trait composition. Our findings demonstrate the usefulness of considering both taxonomic and functional components (functional diversity) in biodiversity research and we suggest a stronger involvement of plant quality measures in Orthoptera studies. © 2017 Institute of Zoology, Chinese Academy of Sciences.

  11. Male responses to conspecific advertisement signals in the field cricket Gryllus rubens (Orthoptera: Gryllidae).

    Jang, Yikweon

    2011-01-20

    In many species males aggregate and produce long-range advertisement signals to attract conspecific females. The majority of the receivers of these signals are probably other males most of the time, and male responses to competitors' signals can structure the spatial and temporal organization of the breeding aggregation and affect male mating tactics. I quantified male responses to a conspecific advertisement stimulus repeatedly over three age classes in Gryllus rubens (Orthoptera: Gryllidae) in order to estimate the type and frequency of male responses to the broadcast stimulus and to determine the factors affecting them. Factors tested included body size, wing dimorphism, age, and intensity of the broadcast stimulus. Overall, males employed acoustic response more often than positive phonotactic response. As males aged, the frequency of positive phonotactic response decreased but that of the acoustic response increased. That is, males may use positive phonotaxis in the early stages of their adult lives, possibly to find suitable calling sites or parasitize calling males, and then later in life switch to acoustic responses in response to conspecific advertisement signals. Males with smaller body size more frequently exhibited acoustic responses. This study suggests that individual variation, more than any factors measured, is critical for age-dependent male responses to conspecific advertisement signals.

Elephantopus mollis H.B.K. (Asteraceae and Hyptis suaveolens Poit. (Lamiaceae comprised 50% of the diet. The diet breadth of A. dilecta was compared to that of other 11 grasshopper species of the same sub-family, with rarefaction curves. The number of plant species eaten by A. dilecta was greater than that of nine other grasshopper species of the same sub-family (Rhachicreagra spp. but was lower then two others (Microptylopteryx hebardi Rehn, 1905 and Rhachicreagra astytophallus Jago & Rowell, 1981.

  15. [Skyblue - the cyanometer of Horace-Bénédict de Saussure (1740 - 1799)].

    Breidbach, Olaf; Karliczek, André

    2011-01-01

    The cyanometer is a simply constructed measuring instrument that enables a determination of skyblue. It consists of a color-scale that is arranged circularly going in equal steps from white to blue (Prussian blue) and finally into black. According to its inventor--Horace-Bénédict de Saussure--the azure is determined by the amount of so called opaque vapors in the atmosphere associated with meteorological phenomena. As outlined by De Saussure, the blackness of the universe seen through an illuminated and blurred medium results in azure. Thereby his instrument offers a relative scale that is consistent with color theories of his time like those of Johann Wolfgang von Goethe. The description allows the construction of the scale without the employment of standardized color-prints. Instead he provides a clear report of the necessary procedures to produce such a scale. The accuracy of this description is tested and discussed employing the methods of experimental history of science. The reception of the cyanometer in the time about 1800 and its implications on color theories is discussed.

    Full Text Available O texto “A presença de Saussure na Teoria da Argumentação na Língua” tem por objetivo avaliar a filiação da teoria, criada por Oswald Ducrot na École de Hautes Études em Sciences Sociales de Paris, a conceitos de Ferdinand de Saussure. È mostrada inicialmente a importância que o Curso de Linguística Geral assumiu , apesar das dificuldades que contém, para a preservação do pensamento de Saussure, e a valiosa contribuição que trouxe para o desenvolvimento de teorias não apenas da linguagem, mas também das ciências humanas, durante o século XX. Dentre os conceitos mais relevantes do saussurianismo são destacados os de relação e de valor. A Teoria da Argumentação na Língua constrói uma interpretação do valor linguístico saussuriano pelo olhar da alteridade que se encontra no diálogo O Sofista de Platão. É a partir dessa noção que Ducrot, excelente conhecedor da Filosofia clássica, desenvolve seu conceito de valor argumentativo, mostrando como, pela relação entre entidades lexicais, é possível explicar os sentidos que se encontram em discursos. Em vista disso, o sentido decorre da linguagem, não é resultado de referência à realidade. Na conclusão, surge uma questão: Ducrot ultrapassou Saussure? Responde-se negativamente, considerando-se que o trabalho de Ducrot, embora seja devedor do pensamento de Saussure, não o continuou, produziu uma semântica sintagmática da língua.

  17. Use of large-scale acoustic monitoring to assess anthropogenic pressures on Orthoptera communities.

    Penone, Caterina; Le Viol, Isabelle; Pellissier, Vincent; Julien, Jean-François; Bas, Yves; Kerbiriou, Christian

    2013-10-01

    Biodiversity monitoring at large spatial and temporal scales is greatly needed in the context of global changes. Although insects are a species-rich group and are important for ecosystem functioning, they have been largely neglected in conservation studies and policies, mainly due to technical and methodological constraints. Sound detection, a nondestructive method, is easily applied within a citizen-science framework and could be an interesting solution for insect monitoring. However, it has not yet been tested at a large scale. We assessed the value of a citizen-science program in which Orthoptera species (Tettigoniidae) were monitored acoustically along roads. We used Bayesian model-averaging analyses to test whether we could detect widely known patterns of anthropogenic effects on insects, such as the negative effects of urbanization or intensive agriculture on Orthoptera populations and communities. We also examined site-abundance correlations between years and estimated the biases in species detection to evaluate and improve the protocol. Urbanization and intensive agricultural landscapes negatively affected Orthoptera species richness, diversity, and abundance. This finding is consistent with results of previous studies of Orthoptera, vertebrates, carabids, and butterflies. The average mass of communities decreased as urbanization increased. The dispersal ability of communities increased as the percentage of agricultural land and, to a lesser extent, urban area increased. Despite changes in abundances over time, we found significant correlations between yearly abundances. We identified biases linked to the protocol (e.g., car speed or temperature) that can be accounted for ease in analyses. We argue that acoustic monitoring of Orthoptera along roads offers several advantages for assessing Orthoptera biodiversity at large spatial and temporal extents, particularly in a citizen science framework. © 2013 Society for Conservation Biology.

  18. Temporal-spatial dynamics in orthoptera in relation to nutrient availability and plant species richness.

    Rob J J Hendriks

    Full Text Available Nutrient availability in ecosystems has increased dramatically over the last century. Excess reactive nitrogen deposition is known to negatively impact plant communities, e.g. by changing species composition, biomass and vegetation structure. In contrast, little is known on how such impacts propagate to higher trophic levels. To evaluate how nitrogen deposition affects plants and herbivore communities through time, we used extensive databases of spatially explicit historical records of Dutch plant species and Orthoptera (grasshoppers and crickets, a group of animals that are particularly susceptible to changes in the C:N ratio of their resources. We use robust methods that deal with the unstandardized nature of historical databases to test whether nitrogen deposition levels and plant richness changes influence the patterns of richness change of Orthoptera, taking into account Orthoptera species functional traits. Our findings show that effects indeed also propagate to higher trophic levels. Differences in functional traits affected the temporal-spatial dynamics of assemblages of Orthoptera. While nitrogen deposition affected plant diversity, contrary to our expectations, we could not find a strong significant effect of food related traits. However we found that species with low habitat specificity, limited dispersal capacity and egg deposition in the soil were more negativly affected by nitrogen deposition levels. Despite the lack of significant effect of plant richness or food related traits on Orthoptera, the negative effects of nitrogen detected within certain trait groups (e.g. groups with limited disperse ability could be related to subtle changes in plant abundance and plant quality. Our results, however, suggest that the changes in soil conditions (where many Orthoptera species lay their eggs or other habitat changes driven by nitrogen have a stronger influence than food related traits.

    Full Text Available Cette communication, qui s’attache à la comparaison des histoires jakobsonienne et saussurienne de la linguistique, s’efforce de montrer que ces deux horizons de rétrospection, que tout oppose (l’histoire jakobsonienne est continuiste et met en valeur l’ancienneté de la science du langage tandis que l’histoire saussurienne, outre qu’elle situe la naissance de la linguistique au dix-neuvième siècle, est au contraire faite de ruptures, impliquent deux constructions distinctes de l’objet de la linguistique, et s’opposent ainsi avant tout comme deux problématiques radicalement différentes. L’histoire jakobsonienne de la linguistique est une synthèse dialectique dont la possibilité se fonde sur un objet donné et totalisant, le langage, dont la définition n’est pas interrogée, et qui fédère également la diversité des linguistiques et des différentes disciplines ayant trait au langage. Saussure nous donne en revanche à lire la constitution progressive d’un objet, en rupture avec la connaissance commune : la langue, objet distinct du langage et objet propre de la linguistique, dont le postulat permet la théorisation du son et du sens comme objets linguistiques et l’étiologie des idiomes. Il apparaît ainsi que l’opposition jakobsonienne à Saussure témoigne avant tout de la résistance d'une problématique présaussurienne. Néanmoins, s’il s’agit là d’épistémologie, il s’agit par ailleurs, corrélativement, et quoi qu’il faille penser de l’histoire saussurienne de la linguistique, de deux mises en œuvre distinctes de l’histoire des sciences : l’une, empirique, celle de Jakobson, l’autre, épistémologique, celle de Saussure.

  20. Revision of the Neotropical bark mantis genus Liturgusa Saussure, 1869 (Insecta, Mantodea, Liturgusini).

    Svenson, Gavin J

    2014-01-01

    The praying mantis genus Liturgusa Saussure, 1869 occurs only in Central and South America and represents the most diverse genus of Neotropical Liturgusini (Ehrmann 2002). The genus includes bark dwelling species, which live entirely on the trunks and branches of trees and run extremely fast. All species included within the genus Liturgusa are comprehensively revised with a distribution stretching from central Mexico, the island of Dominica to the southeastern regions of Brazil and southern Bolivia. All known species are redescribed to meet the standards of the new treatment of the genus (11 species). Three new genera are described including Fuga gen. n., Velox gen. n., and Corticomantis gen. n. for species previously included in Liturgusa as well as Hagiomantis. Liturgusa mesopoda Westwood, 1889 is moved to within the previously described genus Hagiomantis Audinet Serville, 1838. A total of 19 species are newly described within Liturgusa, Fuga, and Velox including L. algorei sp. n., L. bororum sp. n., L. cameroni sp. n., L. cura sp. n., L. dominica sp. n., L. fossetti sp. n., L. kirtlandi sp. n., L. krattorum sp. n., L. manausensis sp. n., L. maroni sp. n., L. milleri sp. n., L. neblina sp. n., L. purus sp. n., L. stiewei sp. n., L. tessae sp. n., L. trinidadensis sp. n., L. zoae sp. n., F. grimaldii sp. n., and V. wielandi sp. n. Four species names are synonymized: Liturgusa peruviana Giglio-Tos, 1914, syn. n. = Liturgusa nubeculosa Gerstaecker, 1889 and Hagiomantis parva Piza, 1966, syn. n., Liturgusa sinvalnetoi Piza, 1982, syn. n., and Liturgusa parva Giglio-Tos, 1914, syn. n. = Mantis annulipes Audinet Serville, 1838. Lectotypes are designated for the following two species: Liturgusa maya Saussure & Zehntner, 1894 and Fuga annulipes (Audinet Serville, 1838). A male neotype is designated for Liturgusa guyanensis La Greca, 1939. Males for eight species are described for the first time including Liturgusa cayennensis Saussure, 1869, Liturgusa lichenalis

  1. Reproductive Status of Females in the Eusocial Wasp Polistes ferreri Saussure (Hymenoptera: Vespidae).

    2014-12-01

    In the subfamily Polistinae, caste dimorphism is not pronounced and differences among females are primarily physiological and behavioral. We investigated factors that indicate the reproductive status in females of Polistes ferreri Saussure. We analyzed females from nine colonies and evaluated morphometric parameters, ovarian development, occurrence of insemination, relative age, and cuticular chemical profile. The colony females showed three kinds of ovarian development: type A, filamentous ovarioles; type B, ovarioles containing partially developed oocytes; and type C, long and well-developed ovarioles containing two or more mature oocytes. The stepwise discriminant analysis of the cuticular chemical profile showed that it was possible to distinguish the three groups of females: workers 1, workers 2, and queens. However, the stepwise discriminant analysis of the morphological differences did not show significant differences among these groups. The queens were among the older females in the colony and were always inseminated, while the age of the workers varied according to the stage of colony development.

    Full Text Available Saussure mudou o mundo ao conceituar a paridade biunívoca do significado e do significante, que chamou em seu Curso de Linguística Geral, signo linguístico. Seguindo seus passos, Roman Jakobson estabeleceu uma fórmula para pensarmos o conceito de metonímia que, por sua vez, foi retomado por Jacques Lacan para enfatizar, entre outras coisas, que o simbólico é, antes de mais nada, um eterno continuum. Dentro dessas perspectivas e com o auxílio desses três pensadores procuramos, neste pequeno artigo, articular certas idiossincrasias da obra de James Joyce, Ulisses, a maior delas sendo, em definitivo, um riverrun que não cessa de se inscrever.

    Full Text Available First report of interspecific facultative social parasitism in the paper wasp genus Mischocyttarus Saussure (Hymenoptera, Vespidae. Parasitism of colonies of the social wasp Mischocyttarus cerberus Ducke, 1918 by females of Mischocyttarus consimilis Zikán, 1949 was observed in a rural area of Dourados, state of Mato Grosso do Sul, Brazil. In all monitored cases, the invasion occurred in the pre-emergence colony stage, generally by a single female of M. consimilis. The period of establishment of the foreign female in the host colony was marked by antagonistic behaviors between the host female and the invasive. In general, the architecture of the parasitized nest was modified from the typical architecture of the host species nest.

    Full Text Available A phylogenetic analysis is presented of subgenera and species-groups of Mischocyttarus de Saussure, the largest genus of social wasps. The analysis is based on 62 morphological and nest architecture characters, coded for 71 terminals representing much of the taxonomic diversity within the genus, plus three outgroup terminals representing other polistine tribes. The main conclusions about phylogenetic relationships within the genus are based on parsimony analysis under implied weights. Monophyly of Mischocyttarus is confirmed as well as that of most of the previously recognized subgenera: Mischocyttarus s. str., Clypeopolybia, Monogynoecus, Scytokeraia, Phi, Kappa, Megacanthopus and Omega sensu Richards (1978. Haplometrobius as conceived by Richards (1978 is not a monophyletic taxon, but some of its species-groups are monophyletic. The groups of M.artifex and M.cerberus are raised to subgenus level, and a new concept of Haplometrobius restricts it to the group of M.iheringi (the type species of this subgenus in the sense of this work. The concept of subgenus Omega is widened to include the species-groups of M.surinamensis and M.prominulus. Besides the new subgeneric classification presented, limits and diagnoses of all species-groups of the subgenera Phi and Haplometrobius sensu Richards (1978 are discussed, and a new key for all subgenera and species-groups of Mischocyttarus is also presented.O artigo apresenta um estudo filogenético dos subgêneros e grupos de espécies de Mischocyttarus de Saussure, o maior dos gêneros de vespas sociais.

  12. Contributions of Gerard de Saussure to fission physics: Subthreshold and near-subthreshold measurements at the ORELA

    Perez, R.B.; Difilippo, F.C.

    1992-01-01

    In the late 1960s, Strutinsky's theoretical work on the structure of the fission barrier, together with some new neutron cross-section measurements performed at Saclay and Gel, was called to Gerard de Saussure's attention, and he immediately recognized the importance of those developments. Indeed, de Saussure was quick to note that for neutron energies in the range of the fission barrier potential energy, fission cross-section measurements would yield direct information about the physical properties of the fission barrier. Under his leadership, a set of extensive and precise measurements was performed at the Oak Ridge Electron Linear Accelerator (ORELA) by an international group of researchers, lasting over two decades. Those measurements were unique in many respects: Fission widths were determined for many previously unreported resonances in the subthreshold region, and a detailed study was performed on the physical properties of the fission barrier at high nuclear deformations. In this paper, we report a specific part of the de Saussure's extensive involvement in the area of subthreshold fission physics: the 1979 measurement of the 238 U(n,f) cross ection in the subthreshold and near-subthreshold regions. This cross section was measured in the energy region between 5 eV and 3.5 MeV using a large fission chamber loaded with high-purity 238 U, which had 235 U

  13. Biodiversity and molecular phylogeny of Australian Clevelandella species (Class Armophorea, Order Clevelandellida, Family Clevelandellidae), intestinal endosymbiotic ciliates in the wood-feeding roach Panesthia cribrata Saussure, 1864.

    Lynn, Denis H; Wright, André-Denis G

    2013-01-01

    There are over 100 species in the Order Clevelandellida distributed in many hosts. The majority is assigned to one of the five families, the Nyctotheridae. Our knowledge of clevelandellid genetic diversity is limited to species of Nyctotherus and Nyctotheroides. To increase our understanding of clevelandellid genetic diversity, species were isolated from intestines of the Australian wood-feeding roach Panesthia cribrata Saussure, 1864 from August to October, 2008. Four morphospecies, similar to those reported in Java and Japan by Kidder [Parasitologica, 29:163-205], were identified: Clevelandella constricta, Clevelandella nipponensis, Clevelandella parapanesthiae, and Clevelandella panesthiae. Small subunit rRNA gene sequences assigned all species to a "family" clade that was sister to the clade of species assigned to the Family Nyctotheridae in the Order Clevelandellida. Genetics and morphology were consistent for the first three Clevelandella species, but isolates assigned to C. panesthiae were assignable to three different genotypes, suggesting that this may be a cryptic species complex. © 2013 The Author(s) Journal of Eukaryotic Microbiology © 2013 International Society of Protistologists.

Resurrection of Scolopendra longipes Wood and Scolopendra cubensis Saussure from synonymy with Scolopendra alternans Leach (Chilopoda, Scolopendromorpha, Scolopendridae): an enigmatic species-group needing phylogeographic analysis, with an overview on the origin and distribution of centipedes in the Caribbean region.

    Mercurio, Randy J

    2016-05-12

    Resurrection of Scolopendra longipes Wood, 1862, and Scolopendra cubensis Saussure, 1860, from junior synonymy with Scolopendra alternans Leach, 1815, is proposed. A neotype specimen of Scolopendra longipes is designated. Scolopendra longipes has a restricted range from the Dry Tortugas up through the Florida Keys of Monroe County into the mainland Florida counties of Collier and Dade southeast to the Bahamas, while Scolopendra cubensis is endemic to Cuba. Characters distinguishing S. longipes, and S. cubensis from S. alternans are illustrated and compared using digital photography, micrography and morphometric data. It is suggested that what has been considered Scolopendra alternans from southern Florida through the Caribbean and into northern South America is probably an evolving species-group that has undergone major diversification sometime during the Paleocene and early Eocene ~65.5-50 million years ago (Ma), mainly due to geographic isolation caused by a combination of plate tectonics and 100,000 year cycles of glaciation/deglaciation.

  15. Soil humus and carbon popularity from 1804 (N. de Saussure) to 2015 (COP 21)

    Feller, Christian; Brevik, Eric

    2017-04-01

    The popularity of humus (or soil organic matter SOM) and later on soil organic carbon (SOC) as related to plant nutrition, soil fertility and environment varied widely from the beginning of the 19th century with the research of Nicolas de Saussure (1804) to Thaer's humus theory (1809) followed by Liebig's mineral theory (1840) until the 20th century with new perceptions of the beneficial roles of SOM. Nowadays, it is known that SOM (with SOC) participates in multiple interactions with the other Earth ecosystem compartments (hydrosphere, biosphere, atmosphere lithosphere). Very recently SOM and SOC were raised to the summit of the international challenges concerning global changes with the French initiative entitled "4 per 1000". Therefore, from the past to the present humus has received varying levels of consideration regarding its benefits for humanity. The central questions of this presentation will be: 1) What were the links between science and society at each of these epistemological steps during these last 200 years, and 2) what were the scientific theories involved?

  17. Sex chromosome diversity in Armenian toad grasshoppers (Orthoptera, Acridoidea, Pamphagidae)

    Bugrov, Alexander G.; Jetybayev, Ilyas E.; Karagyan, Gayane H.; Rubtsov, Nicolay B.

    2016-01-01

    Abstract Although previous cytogenetic analysis of Pamphagidae grasshoppers pointed to considerable karyotype uniformity among most of the species in the family, our study of species from Armenia has discovered other, previously unknown karyotypes, differing from the standard for Pamphagidae mainly in having unusual sets of sex chromosomes. Asiotmethis turritus (Fischer von Waldheim, 1833), Paranocaracris rubripes (Fischer von Waldheim, 1846), and Nocaracris cyanipes (Fischer von Waldheim, 1846) were found to have the karyotype 2n♂=16+neo-XY and 2n♀=16+neo-XX, the neo-X chromosome being the result of centromeric fusion of an ancient acrocentric X chromosome and a large acrocentric autosome. The karyotype of Paranothrotes opacus (Brunner von Wattenwyl, 1882) was found to be 2n♂=14+X1X2Y and 2n♀=14+X1X1X2X2., the result of an additional chromosome rearrangement involving translocation of the neo-Y and another large autosome. Furthermore, evolution of the sex chromosomes in these species has involved different variants of heterochromatinization and miniaturization of the neo-Y. The karyotype of Eremopeza festiva (Saussure, 1884), in turn, appeared to have the standard sex determination system described earlier for Pamphagidae grasshoppers, 2n♂=18+X0 and 2n♀=18+XX, but all the chromosomes of this species were found to have small second C-positive arms. Using fluorescent in situ hybridization (FISH) with 18S rDNA and telomeric (TTAGG)n DNA repeats to yield new data on the structural organization of chromosomes in the species studied, we found that for most of them, clusters of repeats homologous to 18S rDNA localize on two, three or four pairs of autosomes and on the X. In Eremopeza festiva, however, FISH with labelled 18S rDNA painted C-positive regions of all autosomes and the X chromosome; clusters of telomeric repeats localized primarily on the ends of the chromosome arms. Overall, we conclude that the different stages of neo-Y degradation revealed in

    A new species of broad-nosed bat Platyrrhinus Saussure, 1860 (Chiroptera: Phyllostomidae: Stenodermatinae) from the Guianan Shield is described based on molecular and morphological data. Previously confused with P. helleri and P. recifinus, the new taxon is currently known from only Guyana and Suriname and is most closely related to P. recifinus from eastern Brazil and not to the two sympatric species (P. fusciventris and P. incarum) also recently recognized as distinct from P. helleri. Morphometrically the new taxon overlaps with the smaller species of the genus (P. angustirostris, P. brachycephalus, P. fusciventris, P. helleri, P. incarum, and P. matapalensis), but forms a different cluster from the larger P. recifinus. Morphologically the new taxon is distinguished from its congeners by a combination of external and craniodental characteristics. Platyrrhinus now includes 21 species making it the most speciose genus in the Neotropical family Phyllostomidae.

  7. Por que não distinguir sentido próprio de sentido figurado em Saussure e em Ducrot?

    Leci Borges Barbisan

    2017-02-01

    Full Text Available Este texto propõe uma reflexão sobre as noções clássicas de sentido próprio e de sentido figurado, com base em princípios e conceitos apresentados por Ferdinand de Saussure, no Curso de linguística geral e nos Escritos de linguística geral, e por Oswald Ducrot, a propósito da postulação da tese de que a argumentação está na língua. Dentre os conceitos saussurianos mais importantes para as reflexões feitas ao longo deste texto, destacam-se os de arbitrário, de relação e de valor. Ganha o acento este último conceito da teoria de Saussure, visto que é baseado nele e na noção de alteridade apresentada por Platão, em O Sofista, que Ducrot rejeita a existência de um aspecto objetivo na linguagem e une os aspectos subjetivo e intersubjetivo ‒ constitutivos do sentido de enunciados ‒ no que chamou de valor argumentativo. Mantendo-se, portanto, fiel ao modo saussuriano de olhar para a linguagem, Ducrot construiu a Teoria da Argumentação na Língua ‒ « L'Argumentation Dans la Langue » ‒ e defende, até o momento atual da teoria, a hipótese que rejeita a distinção dos tradicionalmente chamados sentidos denotativo e conotativo.

    Qual o lugar da Lingüística e, mais particularmente, de Saussure na constituição e nos desenvolvimentos da Análise do Discurso? Com vistas a refletir sobre a leitura que o grupo em torno de Michel Pêcheux fez do Curso de Lingüística Geral, não buscaremos responder sumariamente a essa questão, antes, tentaremos expor algumas de suas contingências e examinar certas respostas que a ela poderiam ser dadas, considerando as condições de sua emergência e as razões de sua formulação. No intuito de compreender certos aspectos da recepção de Saussure pela AD, recorremos a princípios discursivos e a contribuições da Historiografia lingüística francesa.

  10. Patterns in Orthoptera biodiversity. I. Adaptations in ecological and evolutionary contexts

    Claudio J. Bidau

    2014-10-01

    Full Text Available The Orthoptera have inhabited the Earth for ca 300 million years and today include about 25,000 described species. Although orthopterans are mainly known to the general public by their most conspicuous species such as rangeland grasshoppers, locusts, katydids and crickets, they include an amazing diversity of forms and life-styles. In this review, I bring together a series of facts about orthopteran biology that demonstrate their enormous biodiversity, concentrating on ecological and evolutionary characteristics such as habitat variation, modes of feeding, defense mechanisms and phase transformation. In a second part of this review I will consider subjects of more direct human interest as their use as food, their importance in folk medicine and their role as entertainment.

  11. Structural and biological characterization of three novel mastoparan peptides from the venom of the neotropical social wasp Protopolybia exigua (Saussure).

    Mendes, Maria Anita; de Souza, Bibiana Monson; Palma, Mario Sergio

    2005-01-01

    The venom of the Neotropical social wasp Protopolybia exigua(Saussure) was fractionated by RP-HPLC resulting in the elution of 20 fractions. The homogeneity of the preparations were checked out by using ESI-MS analysis and the fractions 15, 17 and 19 (eluted at the most hydrophobic conditions) were enough pure to be sequenced by Edman degradation chemistry, resulting in the following sequences: Protopolybia MPI I-N-W-L-K-L-G-K-K-V-S-A-I-L-NH2 Protopolybia-MP II I-N-W-K-A-I-I-E-A-A-K-Q-A-L-NH2 Protopolybia-MP III I-N-W-L-K-L-G-K-A-V-I-D-A-L-NH2 All the peptides were manually synthesized on-solid phase and functionally characterized. Protopolybia-MP I is a hemolytic mastoparan, probably acting on mast cells by assembling in plasma membrane, resulting in pore formation; meanwhile, the peptides Protopolybia-MP II and -MP III were characterized as a non-hemolytic mast cell degranulator toxins, which apparently act by virtue of their binding to G-protein receptor, activating the mast cell degranulation.

  13. Three new species of freshwater crabs of the genus Pseudothelphusa (De Saussure, 1857) (Crustacea: Decapoda: Pseudothelphusidae) from Mexico.

    Ojeda-Escoto, Juan Carlos; Villalobos, José Luis; Álvarez, Fernando

    2017-01-11

    Three new species of freshwater crabs of the genus Pseudothelphusa (De Saussure, 1857) from south-central Mexico are described: Pseudothelphusa acahuizotla n. sp., P. ixtapan n. sp., and P. purhepecha n. sp. The new species are included in Pseudothelphusa due to a male gonopod with torsion and the presence of the characteristic mesial process and caudomarginal projection. Pseudothelphusa acahuizotla n. sp. is morphologically similar to P. belliana Rathbun, 1898, but can be distinguished by the relative size of the distal lobe of the caudomarginal projection and by the presence of a conical tooth on the caudal surface of the mesial process of the male gonopod. Pseudothelphusa ixtapan n. sp. is similar to P. dilatata Rathbun, 1898, and P. morelosis Pretzmann, 1968, and can be distinguished by a mesial process of the male gonopod with only one lateral tooth and an inferior margin with small teeth. Pseudothelphusa puerhepechae n. sp. exhibits a mesial process of the male gonopod with two triangular spines on its lateral margin, a character that with some variations is present in P. nayaritae Álvarez & Villalobos, 1994, P. rechingeri Pretzmann, 1965, P. lophophallus Rodríguez & Smalley, 1969, and P. parabelliana Álvarez 1989; but it can be distinguished by the separation and shape of the two spines of the mesial process and the shape of the lobes of the caudomarginal projection. With the new species described herein there are now 29 species in the genus Pseudothelphusa.

    Resumo. O sucesso das espécies de vespas sociais está relacionado tanto a construção quanto a manutenção das colônias. Várias espécies utilizam de diversas estratégias para evitar a predação de seus ninhos, como a associação com outros insetos e vertebrados. O presente estudo descreve o primeiro registro da associação da vespa social Chartergus globiventris Saussure com a ave Tolmomyias sulphurescens Spix em fragmento de Floresta Estacional Decidual no Sudeste do Brasil. Foram registradas oito colônias de C. globiventris ativas em diferentes espécies arbóreas, das quais três estavam associadas a ninhos ativos de T. sulphurescens. A associação entre a ave e a vespa tem sido tratada como comensalismo, pois apenas a ave obtém vantagens aparente, como discutido na literatura. Contudo, é necessário realizar experimentações ou análises mais aprofundadas a fim de se obter afirmações sobre os benefícios dessa relação.

    Three new species of Ripipteryx Newman (Orthoptera: Tridactyloidea: Ripipterygidae) are described from Colombia; namely Ripipteryxdiegoi sp. n. (Forceps Group) and Ripipteryxguacharoensis sp. n. (Marginipennis Group) from Parque Nacional Natural Cueva de los Guacharos in Huila, and Ripipteryxgorgonaensis sp. n. (Crassicornis Group) from Parque Nacional Natural Gorgona in Cauca. Ripipteryxdiegoi sp. n. is characterized by the antennae black with white spots on flagellomeres 3-7, male subgenital plate with median ridge forming a bilobed setose process, epiproct produced laterally near its base and phallic complex with virga thickened distally and not reaching beyond the membrane. Ripipteryxguacharoensis sp. n. is characterized by the antennae thick with white spots present dorsally on flagellomeres 1-4 and 8, epiproct narrow and triangular, uncus reduced and lacking a distal hook, phallic complex with a concave ventral plate and a dorsal elevation in the middle extended to the virga, and the virga itself with two small projections basally. Ripipteryxgorgonaensis sp. n. is characterized by the epiproct with a lateral notch, antennae with a white dorsal spot on flagellomere 1 and flagellomeres 4-7 entirely white. The antennal color pattern of Ripipteryxgorgonaensis sp. n. strongly resembles that of Ripipteryxatra but differs from the latter in the absence of any significant morphological modification of the flagellomeres.

    Analyses of species traits have increased our understanding of how environmental drivers such as disturbances affect the composition of arthropod communities and related processes. There are, however, few studies on which traits in the arthropod community are affected by environmental changes and which traits affect ecosystem functioning. The assembly of arthropod traits of several taxa is difficult because of the large number of species, limited availability of trait databases and differences in available traits. We sampled arthropod species data from a total of 150 managed grassland plots in three regions of Germany. These plots represent the spectrum from extensively used pastures to mown pastures to intensively managed and fertilized meadows. In this paper, we summarize information on body size, dispersal ability, feeding guild and specialization (within herbivores), feeding mode, feeding tissue (within herbivorous suckers), plant part (within herbivorous chewers), endophagous lifestyle (within herbivores), and vertical stratum use for 1,230 species of Coleoptera, Hemiptera (Heteroptera, Auchenorrhyncha), Orthoptera (Saltatoria: Ensifera, Caelifera), and Araneae, sampled by sweep-netting between 2008 and 2012. We compiled traits from various literature sources and complemented data from reliable internet sources and the authors’ experience.

  2. Morphology and fine organization of the spermatheca of Haplotropis brunneriana (Orthoptera: Pamphagidae

    Full Text Available We investigated the morphology and structure of spermatheca in Haplotropis brunneriana (Orthoptera: Pamphagidae by light and electronic microscopy. The spermatheca can be subdivided into a tubular seminal receptacle and a multiple-coiled spermathecal tube, both of which are composed of cuticular intima, epithelium layer, basal lamina and muscle layer, from inside to outside. The cuticular intima is made up of a heterogeneous endocuticle, a homogeneous exocuticle and an epicuticle, but the proportion of exocuticle in intima of the seminal receptacle is larger than that of the spermathecal tube. The epithelium layer comprises epithelial cells, gland cells and duct cells. The ultrastructural features of the epithelial cells indicated that its function potentially includes support, secretion and absorption. The gland cells potentially fulfil a secretory role indicative of the abundance of mitochondria and microvilli. In gland cells, an extracellular cavity, showing region differences in the seminal receptacle and the spermathecal tube, was lined with microvillus border. The role of duct cell is responsible for forming the secretory ductules, which connect the extracellular cavity with the lumen of the spermatheca through the cuticular intima. These new data contribute to our understanding of the function of the spermatheca of H. brunneriana. Keywords: Ultrastructure, Seminal receptacle, Spermathecal tube

    2015-04-01

    Comet assay was applied to study genotoxic damage induced by paraquat (PQ) in brain cells of Chorthippus brunneus (Insecta: Orthoptera) hatchlings. Percentage of the comet fluorescence in the tail (TDNA), length of the comet tail (TL) and Olive tail moment (OTM) were used for quantitative assessment of the DNA damage. Multiple regression analysis supplemented standard statistical elaboration of the results. Increasing PQ concentrations applied either directly to the brain cells suspension (10, 50, and 250 μM PQ final concentration--in vitro protocol) or indirectly (50, 250, and 1250 μM PQ final concentration--in vivo protocol) provoked significant increase of oxidative damage to DNA (higher median TDNA and OTM values). The damage increased with time of exposure (0, 5, 15, and 30 min) following in vitro application, but decreased in longer interval (3 vs 24 h) after in vivo administration of paraquat. On contrary, median TL values did not correlate with paraquat concentration irrespectively of the exposure protocol. Possible reason of this discrepancy in light of paraquat toxicity is discussed.

  5. Complete mitochondrial genome of the Chinese endemic grasshopper Fruhstorferiola kulinga (Orthoptera: Acrididae: Podismini).

    Yang, Rui; Guan, De-Long; Xu, Sheng-Quan

    2016-09-01

    The whole-genome Illumina sequence of the Chinese endemic grasshopper Fruhstorferiola kulinga mitogenome was constructed and reported in this study. In all, the circular genome was obtained with 15,655 bp in length and contains 75.4% A + T. It typically consists of 37 genes, including 13 protein-coding genes (PCGs), 22 transfer RNAs (tRNAs), 2 ribosomal RNAs (rRNAs) and 1 D-loop region. All PCGs are initiated with ATN codons. Most of the PCGs use TAA as their stop codons, while the others use TAG as stop codons (COX1 and ND1). The size of the large and small ribosomal RNA genes are 1314 bp and 851 bp. The A + T-rich region (777 bp) showed strong resemblance to the other known Orthoptera insects. Our data would contribute to confirm the close relationship and other evolutionary researches of the F. kulinga.

    Full Text Available Abstract This work provides the results of a survey of entomonematodes parasites of grasshoppers in grasslands of the Pampean Region, Argentina. Nymphs of Staurorhectus longicornis Giglio-Tos, Laplatacris dispar Rhen, 1939, Dichroplus elongatus Giglio-Tos, 1894 and Metaleptea brevicornis (L. (Orthoptera: Acrididae were collected. Mermithidae was the only family registered with seven species: Agamermis decaudata Cobb, Steiner and Christie, 1923, Amphimermis bonaerensis Miralles and Camino, 1983, Amphimermis dichroplusi Camino and Lange, 1997, Amphimermis ronderosi Camino and Lange, 1997, Hexamermis coclhearius Stock and Camino, 1992, Hexamermis ovistriata Stock and Camino, 1992, and Longimermis acridophila Camino and Stock, 1989. The values of parasitism ranged between 1-12%, and intensity not overcome the number of 5.0 nematodes per larva. The nematodes observed showed specificity, not registering the same species of parasite in more than one host species. The Pampean region constituted an area with high diversity of mermithids where new species could be consider as bioregulator agents of this troublesome insect pests in agricultural areas of Argentina.

  7. Adaptive colour polymorphism of Acrida ungarica H. (Orthoptera: Acrididae) in a spatially heterogeneous environment

    Intra-specific colour polymorphism provides a cryptic camouflage from predators in heterogeneous habitats. The orthoptera species, Acrida ungarica (Herbst, 1786) possess two well-distinguished colour morphs: brown and green and displays several disruptive colouration patterns within each morph to improve the crypsis. This study focused on how the features of the background environment relate to the proportion of the two morphs and to the intensity of disruptive colouration patterns in A. ungarica. As the two sexes are very distinct with respect to mass and length, we also distinctively tested the relationship for each sex. In accordance with the background matching hypothesis, we found that, for both sexes, the brown morph was in higher proportion at sites with a brown-dominant environment, and green morphs were in higher proportion in green-dominant environments. Globally, individuals in drier sites and in the drier year also had more intense disruptive colouration patterns, and brown morphs and females were also more striped. Colour patterns differed largely between populations and were significantly correlated with relevant environmental features. Even if A. ungarica is a polymorphic specialist, disruptive colouration still appears to provide strong benefits, particularly in some habitats. Moreover, because females are larger, they are less able to flee, which might explain the difference between sexes.

  8. Phylogeography and systematics of the westernmost Italian Dolichopoda species (Orthoptera, Rhaphidophoridae)

    Allegrucci, Giuliana; Rampini, Mauro; Di Russo, Claudio; Lana, Enrico; Cocchi, Sara; Sbordoni, Valerio

    2014-01-01

    Abstract The genus Dolichopoda (Orthoptera; Rhaphidopohoridae) is present in Italy with 9 species distributed from northwestern Italy (Piedmont and Liguria) to the southernmost Apennines (Calabria), occurring also in the Tyrrhenian coastal areas and in Sardinia. Three morphologically very close taxa have been described in Piedmont and Liguria, i.e., D. ligustica ligustica, D. ligustica septentrionalis and D. azami azami. To investigate the delimitation of the northwestern species of Dolichopoda, we performed both morphological and molecular analyses. Morphological analysis was carried out by considering diagnostic characters generally used to distinguish different taxa, as the shape of epiphallus in males and the subgenital fig in females. Molecular analysis was performed by sequencing three mitochondrial genes, 12S rRNA, 16S rRNA, partially sequenced and the entire gene of COI. Results from both morphological and molecular analyses highlighted a very homogeneous group of populations, although genetically structured. Three haplogroups geographically distributed could be distinguished and based on these results we suggest a new taxonomic arrangement.

    Full Text Available The genus Dolichopoda (Orthoptera; Rhaphidopohoridae is present in Italy with 9 species distributed from northwestern Italy (Piedmont and Liguria to the southernmost Apennines (Calabria, occurring also in the Tyrrhenian coastal areas and in Sardinia. Three morphologically very close taxa have been described in Piedmont and Liguria, i.e., D. ligustica ligustica, D. ligustica septentrionalis and D. azami azami.To investigate the delimitation of the northwestern species of Dolichopoda, we performed both morphological and molecular analyses. Morphological analysis was carried out by considering diagnostic characters generally used to distinguish different taxa, as the shape of epiphallus in males and the subgenital plate in females. Molecular analysis was performed by sequencing three mitochondrial genes, 12S rRNA, 16S rRNA, partially sequenced and the entire gene of COI.Results from both morphological and molecular analyses highlighted a very homogeneous group of populations, although genetically structured. Three haplogroups geographically distributed could be distinguished and based on these results we suggest a new taxonomic arrangement. All populations, due to the priority of description, should be assigned to D. azami azami Saulcy, 1893 and to preserve the names ligustica and septentrionalis, corresponding to different genetic haplogroups, we assign them to D. azami ligustica Baccetti & Capra, 1959, stat. n. and to D. azami septentrionalis Baccetti & Capra, 1959, stat. n.

    Full Text Available Anaxipha longipennis Serville (Orthoptera: Gryllidae is one of the generalist predator in rice habitat that has a potential as a biological control agents of rice leaf folder eggs and small insects such as rice hoppers. Females insert their eggs in plant tissue. The female’s oviposition site is important for the subsequent distribution of the cricket. Oviposition preference on 17 weeds species from rice habitat were tested in a free choice experiment in the laboratory. There was strong evidence to conclude that the cricket preferred certain plant for laying eggs. In free choice experiment nine species of weeds were preferred by A. longipennis for laying their eggs instead of rice. The preferred species were ranked as follows: rice, Monochoria vaginalis, Cyperus rotundus, C. iria, Echinochloa colonum, E. crusgalli, Eleusine indica, Fimbristylis miliacea, Imperata cylindrica, and Limnocharis flava. Whereas Ageratum conyzoides, Alternanthera sessilis, Commelina diffusa, Leersia hexandra, Leptochloa chinensis, Ludwigia adscendens, Panicum repens, and Sonchus arvensis were not preferred in free-choice test.

  11. Revisiting adaptations of neotropical katydids (Orthoptera: Tettigoniidae) to gleaning bat predation.

    2017-01-01

    All animals have defenses against predators, but assessing the effectiveness of such traits is challenging. Neotropical katydids (Orthoptera: Tettigoniidae) are an abundant, ubiquitous, and diverse group of large insects eaten by a variety of predators, including substrate-gleaning bats. Gleaning bats capture food from surfaces and usually use prey-generated sounds to detect and locate prey. A number of Neotropical katydid signaling traits, such as the emission of ultrasonic frequencies, substrate vibration communication, infrequent calling, and ultrasound-evoked song cessation are thought to have evolved as defenses against substrate-gleaning bats. We collected insect remains from hairy big-eared bat ( Micronycteris hirsuta ) roosts in Panama. We identified insect remains to order, species, or genus and quantified the proportion of prey with defenses against predatory bats based on defenses described in the literature. Most remains were from katydids and half of those were from species with documented defenses against substrate-gleaning bats. Many culled remains were from insects that do not emit mate-calling songs (e.g. beetles, dragonflies, cockroaches, and female katydids), indicating that eavesdropping on prey signals is not the only prey-finding strategy used by this bat. Our results show that substrate-gleaning bats can occasionally overcome katydid defenses.

  12. Nonintegrated Host Association of Myrmecophilus tetramorii, a Specialist Myrmecophilous Ant Cricket (Orthoptera: Myrmecophilidae

    2013-01-01

    Full Text Available Myrmecophilus ant crickets (Orthoptera: Myrmecophilidae are typical ant guests. In Japan, about 10 species are recognized on the basis of morphological and molecular phylogenetic frameworks. Some of these species have restricted host ranges and behave intimately toward their host ant species (i.e., they are host specialist. We focused on one species, M. tetramorii, which uses the myrmicine ant Tetramorium tsushimae as its main host. All but one M. tetramorii individuals were collected specifically from nests of T. tsushimae in the field. However, behavioral observation showed that all individuals used in the experiment received hostile reactions from the host ants. There were no signs of intimate behaviors such as grooming of hosts or receipt of mouth-to-mouth feeding from hosts, which are seen in some host-specialist Myrmecophilus species among obligate host-ant species. Therefore, it may be that M. tetramorii is the species that is specialized to exploit the host by means other than chemical integration.

    Full Text Available In 2008 we found 21 species of grasshoppers and crickets on Macošská stráň slope and 18 species on Vilémovická stráň slope. Both slopes are located in the northern part of the Moravský kras Protected landscape area and have xerothermic character. Both slopes are influenced by pasture management. For the most comprehensive picture of Orthoptera we used a standard method (sweeping of vegetation and nonstandard methods (pitfall traps and Möricke yellow cups. Termophilous species of Orthoptera on Macošská stráň (47% were dominating. On Vilémovická stráň mezophilous species (46% were dominating. The most common species were Stenobothrus lineatus (Panzer, 1796 on Macošská stráň slope and Chorthippus parallelus (Zetterstedt, 1821, Stenobothrus lineatus, Chorthippus bigutulus (Linné, 1758 and Chorthippus dorsatus (Zetterstedt, 1821 on Vilémovická stráň slope. Rare species of this assemblage were Stenobothrus nigromaculatus (Herrich-Schaffer, 1840 which was on Macošská stráň slope only and Tetrix bipunctata (Linnaeus, 1758 which has much bigger abundances also on Macošská stráň slope.

    Full Text Available For the territory of Samarskaya Luka, at the village Bakhilova Polyana (I.I. Sprygin Zhiguli State Natural Biosphere Reserve, 25 species of Orthoptera were found in mid-July 2016. These species were identified basically by the analysis of male acoustic signals. This is 44% of the total species composition of Samarskaya Luka Orthoptera, specified in the Cadastre of invertebrates of Samarskaya Luka. The specimens belonging to the grasshopper Platychleis albopunctata (= P. intermedia auct. are clarified. The cricket Melanogryllus desertus and the locust Chorthippus dorsatus were found for the first time in the Samarskaya Luka. The species composition of the cryptic taxa of the «Chorthippus biguttulus group» of the Middle Volga region is discussed. Based on the unstable amplitude-time structure of the signals of the supposed Ch. biguttulus males from Malaya Bahilova Mountain, it is assumed that they may have a hybrid origin.

  4. A preliminary mitochondrial genome phylogeny of Orthoptera (Insecta) and approaches to maximizing phylogenetic signal found within mitochondrial genome data.

    2008-10-01

    The phylogenetic utility of mitochondrial genomes (mtgenomes) is examined using the framework of a preliminary phylogeny of Orthoptera. This study presents five newly sequenced genomes from four orthopteran families. While all ensiferan and polyneopteran taxa retain the ancestral gene order, all caeliferan lineages including the newly sequenced caeliferan species contain a tRNA rearrangement from the insect ground plan tRNA(Lys)(K)-tRNA(Asp)(D) swapping to tRNA(Asp) (D)-tRNA(Lys) (K) confirming that this rearrangement is a possible molecular synapomorphy for this suborder. The phylogenetic signal in mtgenomes is rigorously examined under the analytical regimens of parsimony, maximum likelihood and Bayesian inference, along with how gene inclusion/exclusion, data recoding, gap coding, and different partitioning schemes influence the phylogenetic reconstruction. When all available data are analyzed simultaneously, the monophyly of Orthoptera and its two suborders, Caelifera and Ensifera, are consistently recovered in the context of our taxon sampling, regardless of the optimality criteria. When protein-coding genes are analyzed as a single partition, nearly identical topology to the combined analyses is recovered, suggesting that much of the signals of the mtgenome come from the protein-coding genes. Transfer and ribosomal RNAs perform poorly when analyzed individually, but contribute signal when analyzed in combination with the protein-coding genes. Inclusion of third codon position of the protein-coding genes does not negatively affect the phylogenetic reconstruction when all genes are analyzed together, whereas recoding of the protein-coding genes into amino acid sequences introduces artificial resolution. Over-partitioning in a Bayesian framework appears to have a negative effect in achieving convergence. Our findings suggest that the best phylogenetic inferences are made when all available nucleotide data from the mtgenome are analyzed simultaneously, and that

  5. Food supply (Orthoptera, Mantodea, Rodentia and Eulipotyphla and food preferences of the red-footed falcon (Falco vespertinus in Slovakia

    Krištín Anton

    2017-12-01

    Full Text Available Food supply in the nesting territories of species has a key role to the species diet composition and their breeding success. Red-footed falcon (Falco vespertinus preys predominantly on larger insect species with a supplementary portion of smaller vertebrates. In the breeding periods 2014 and 2016 their food supply, focusing on Orthoptera, Mantodea, Rodentia and Eulipotyphla, was analysed at five historical nesting sites of the species in Slovakia. Preference for these prey groups in the diet was also studied at the last active nesting site in this country. Overall we recorded 45 Orthoptera species (of which 23 species are known as the food of the red-footed falcon, one species of Mantodea, 10 species of Rodentia (of which 2 species are known as the food of the red-footed falcon and 5 species of the Eulipotyphla order in the food supply. With regard to the availability of the falcons' preferred food, in both years the most suitable was the Tvrdošovce site, which continuously showed the greatest range and abundance of particular species. In the interannual comparison the insects showed lower variability in abundance than the small mammals. In 2014 the growth of the common vole (Microtus arvalis population culminated and with the exception of a single site (Bodza a slump in abundance was recorded in 2016. In comparing the diet composition with the food supply at the last Slovak breeding site Rusovce (Special Protection Area Sysľovské polia, we recorded significant preference for grasshopper Caliptamus italicus (in 2014, common vole (in 2016 and cricket Tettigonia viridissima (in both years in the falcons' diet. They did not prey on the Apodemus sylvaticus species belonging among the abundant small mammal species in that locality. Conservation measures in the agricultural landscape are discussed in relation to homogeneous red-footed falcon breeding territories.

  6. ALGUNS ASPECTOS DA RELAÇÃO ENTRE A TEORIA SAUSSURIANA DA LINGUAGEM E A TEORIA DO SIGNIFICANTE LACANIANO A FEW ASPECTS OF THE RELATION ENTER THE SAUSSURE'S THEORY OF THE LANGUAGE AND THE THEORY OF THE LACAN'S SIGNIFICANT

    Sergio Augusto Franco Fernandes

    2010-05-01

    Full Text Available Faz-se necessário uma busca de elementos que venham a facilitar a compreensão das origens do significante lacaniano, na tentativa de esclarecer, pela via do estruturalismo lingüístico, até onde vai, realmente, a influência saussuriana. Sabe-se que o significante lacaniano, mesmo tendo como referência epistemológica o significante saussuriano, ambos não devem ser confundidos. Normalmente se atribui a Ferdinand de Saussure a invenção da teoria do signo. Ressaltaremos, entretanto, que essa “invenção” é bem anterior às teorias do lingüista genebrino. Levaremos em conta as observações de Jean-Luc Nancy e Philippe Lacoue-Labarthe, na medida em que esses autores demonstram que o deslocamento operado sobre o esquema saussuriano não vai depender, como comumente se pensa, da autonomia do significante. Verificaremos, portanto, até que ponto mostra-se legítimo o uso do termo significante na teoria lacaniana.A search of elements becomes necessary to facilitate the understanding of the origins of the Lacan´s significant, in the attempt to explain through structural linguistic, the limits of the Saussure´s influence. It is known that the Lacan´s significant, even though has the Saussure´s influence as a reference in epistemology, both “significant” must not be mistaken. It is usually attributed to Ferdinand de Saussure the invention of the theory of the linguistic sign. We will stand out, however, that this “invention” is previous to the theories of the genevan linguist. We will observe the comments of Jean-Luc Nancy and Philippe Lacoue-Labarthe, to the point where these authors demonstrate that the displacement operated on the Saussure´s scheme will not depend on, as it is well known, the significant’s autonomy. It will be verified, therefore, how legitimate it is, the use of the significant´s term in the Lacan´s theory.

  12. Radio-telemetric evidence of migration in the gregarious but not the solitary morph of the Mormon cricket (Anabrus simplex: Orthoptera: Tettigoniidae)

    Lorch, Patrick D.; Gwynne, D. T.

    The Mormon cricket, Anabrus simplex, is one of just a few species of katydids (or bushcrickets, Orthoptera: Tettigoniidae) that, like migratory locusts, appear to have solitary and migratory morphs. Using radio telemetry we studied movements of individuals of two morphs of this flightless species. Individuals within each migratory band had similar rates of movements along similar directional headings whereas solitary individuals moved little and showed little evidence of directionality in movement. Our results also add to other recent radio-telemetry studies showing that flightless insects of 1-2g in mass can be tracked successfully using these methods.

    Chorthippus vagans is a common species of Gomphocerinae (Orthoptera) on the Iberian Peninsula. It is endangered in Central Europe where information about its ecological requirements is available; however, aspects of its biology are almost unknown in Mediterranean ecosystems, where it is widespread and common. The focus of this study was to determine how C. vagans adjusts its biology to environmental features of this ecosystem and to interpret how it may be affected by the ecological changes related to the re-vegetation programme linked to the construction of the Breña dam (SW Spain). The research parameters included the autoecology, feeding response and some aspects of reproduction of this species in the Southern Iberian Peninsula. To determine the local distribution and phenology of C. vagans, monthly samplings were conducted (2007-2010) in 12 sampling plots. For the food selection tests, ten nymphs and ten adults were placed individually in insectaries under controlled conditions. Grasses (Lolium sp.) and shrubs (Cistus sp.) were supplied ad libitum in two types of tests, monospecific and mixed diet. The reproductive biology was analysed by both observations of anatomical structures (integument, bristles, tibial spines, tarsal claws and mandibles) and ovarian dissections of 29 females and in laboratory rearing experiments with 15 pairs of adults. The results indicate that C. vagans shows an extended activity period which peaks at the end of summer. It is a polyphagous grasshopper, although adults show a slight preference for grasses. In addition, it is a univoltine species with spring-summer breeding activity.

    In order to describe grasshopper (Orthoptera: Acrididae) species composition, diversity, abundance, and density of four rangelands types, we compared the grasshopper community composition and dynamics in the rangeland of the northern slopes of the Qilian Mountains. In total, 55 grasshopper species were collected from 2007 to 2009, representing three families and six subfamilies. The subfamily Oedipodinae was dominant, followed by Gomphocerinae and Catantopinae. Species abundance varied among rangeland types (RTs). The greatest abundance of grasshoppers was found in mountain rangeland, while the lowest abundance of grasshoppers was caught in alpine shrublands. Three species (Chorthippus cf. brunneus (Thunberg) (Acrididae), Chorthippus Dubius (Zubovski), and Gomphocerus licenti (Chang) were broadly distributed in the four RTs and constituted 7.5% of all grasshoppers collected. Ch. dubius was very abundant in desert rangeland and alpine shrubland. Bryodema dolichoptera Yin et Feng Eremippus qilianshanensis Lian and Zheng, and Filchnerella qilianshanensis Xi and Zheng (Pamphagidae) were endemic to the region of the Qilian Mountains. Species similarity between RTs ranged from 17.8 to 51.6 based on the Renkonen index. Similarly, the Sörensen index indicated a wide separation in species composition among RTs. The abundance of the eight most common species showed obvious differences among RTs and years. On average, mountain rangeland had the highest density values in 2007 and 2008, and alpine shrubland supported the smallest density. The densities in desert and mountain rangeland in 2007 were significantly higher than in 2008, while alpine rangeland and shrublands did not present obvious differences among years. © The Author 2015.

  18. Olfactory signaling of aggressive intent in male-male contests of cave crickets (Troglophilus neglectus; Orthoptera: Rhaphidophoridae.

    Nataša Stritih

    Full Text Available In animal contests, communicating aggressive motivation is most often mediated by visual or acoustic signals, while chemical signals are not expected to serve such a function since they are less able to be modulated by the sender during the changing behavioral context. We describe a rare example of ephemeral olfactory signals in terrestrial animals, signals that are emitted via protrusive scent glands in male cave crickets Troglophilus neglectus (Orthoptera, Rhaphidophoridae to reflect the state of the signaler's aggression. We correlate the intensity of behaviorally expressed aggression of the individuals in dyadic contests with the frequency and extent of their gland tissue protrusion, the latter serving as an indication of the amount of released odor. We detected large amounts of odor release during brief gland protrusions, and the absence of its release during gland retraction. Males protruded the glands during and after encountering a rival, with the degree of protrusion increasing with the intensity of the signalers' aggression. During the encounters, the degree of gland protrusion increased most strongly with the occurrence of the elevated body posture, directly preceding the attack. This degree was significantly higher in encounter winners than in losers displaying such posture, suggesting the highly important role of the released odor for contest resolution. After the encounters, glands were protruded almost exclusively by winners, apparently announcing victory. We tested for the function of the olfactory signals also directly, by preventing gland tissue protrusion in symmetric and asymmetric treatments of the contestants. Treating only the dominant individuals decreased the percentage of encounters they won by over 60%, while treating both contestants elicited a significant increase in the frequency and duration of fights. During contests, the olfactory signals of T. neglectus apparently function as a highly effective threat, which

  19. Neuronal Regression of Internal Leg Vibroreceptor Organs in a Cave-Dwelling Insect (Orthoptera: Rhaphidophoridae: Dolichopoda araneiformis).

    Strauß, Johannes; Stritih, Nataša

    2017-01-01

    Animals' adaptations to cave habitats generally include elaboration of extraoptic senses, and in insects the receptor structures located on the legs are supposed to become more prominent in response to constant darkness. The receptors for detecting substrate vibrations are often highly sensitive scolopidial sensilla localized within the legs or the body. For troglobitic insects the evolutionary changes in vibroreceptor organs have not been studied. Since rock is an extremely unfavorable medium for vibration transmission, selection on vibration receptors may be weakened in caves, and these sensory organs may undergo regressive evolution. We investigated the anatomy of the most elaborate internal vibration detection system in orthopteroid insects, the scolopidial subgenual organ complex in the cave cricket Dolichopoda araneiformis (Orthoptera: Ensifera: Rhaphidophoridae). This is a suitable model species which shows high levels of adaptation to cave life in terms of both phenotypic and life cycle characteristics. We compared our data with data on the anatomy and physiology of the subgenual organ complex from the related troglophilic species Troglophilus neglectus. In D. araneiformis, the subgenual organ complex contains three scolopidial organs: the subgenual organ, the intermediate organ, and the accessory organ. The presence of individual organs and their innervation pattern are identical to those found in T. neglectus, while the subgenual organ and the accessory organ of D. araneiformis contain about 50% fewer scolopidial sensilla than in T. neglectus. This suggests neuronal regression of these organs in D. araneiformis, which may reflect a relaxed selection pressure for vibration detection in caves. At the same time, a high level of overall neuroanatomical conservation of the intermediate organ in this species suggests persistence of the selection pressure maintaining this particular organ. While regressive evolution of chordotonal organs has been documented for

    Marabuto, Eduardo

    2014-01-01

    The recent growing interest on the Mantodea fauna of southern Europe and Portugal in particular, has enabled the discovery of two geographically separated populations of hitherto unknown species in Europe. Analysis of specimens shows that they belong to two Afrotropical mantids: Miomantiscaffra Saussure, 1871 and Miomantispaykullii Stal, 1871, thus raising the number of known species in Europe to 39 and in Portugal to 11. While these are remarkable findings, they also represent the first alien mantis species recorded from this continent. As yet, these species appear to be confined to artificial humanised gardened areas but call for more attention to the problem of biological invasions and the need for better bio-security measures for the conservation of natural ecosystems. In the absence of recent revisionary work on the Mantodea of Portugal and given the need to provide an accessible identification tool, both a checklist and a key to species are provided for all species in the country.

  5. Exposure to exogenous enkephalins disrupts reproductive development in the Eastern lubber grasshopper, Romalea microptera (Insecta: Orthoptera.

    Sandeep Kumar

    Full Text Available Enkephalins play a major role in reproductive physiology in crustaceans; however their role in reproductive development in insects is largely unknown. We investigated the effect of exposure to exogenous leucine-enkephalin (Leu-Enk, methionine-enkephalin (Met-Enk, and the opioid antagonist naloxone on gonad development in the Eastern lubber grasshopper, Romalea microptera. Injection of either Leu-Enk or naloxone alone significantly increased the testicular index and testicular follicular diameter in males, and the ovarian index, oocyte length, and oocyte diameter in females. In contrast, injection of Met-Enk inhibited all measures of reproductive development in both sexes. Surprisingly, co-injection of naloxone with either enkephalin enhanced the effect associated with administration of the enkephalin alone. This study clearly demonstrates the ability of enkephalins to disrupt insect sexual development and also suggests the existence of conserved enkephaline-dependent regulatory mechanisms in insects and crustaceans.

    The genus Scelio is a cosmopolitan and speciose group of solitary parasitoids of the eggs of short-horned grasshoppers (Orthoptera: Acrididae). A number of these hosts are important pests, including plague locusts of the genus Schistocerca. Species of Scelio are recognized as potentially important biological control agents, but this possibility has yet to be fully realized, in part because the species-level taxonomy is still incompletely developed. The species of the pulchripennis group have been recently revised. As a continuation of this effort, here we revise the Afrotropical species of Scelio, excluding the pulchripennis species group. Sixty two (62) species are treated, 48 of which are new. Species are classified into the following species groups: ernstii (12 species, 9 new), howardi (23 species, 19 new), ipomeae (6 species, 5 new), irwini (4 species, 3 new), simoni (3 new species) and walkeri (12 species, 9 new). Keys to species groups and to the species within each group are provided.

    2012-10-01

    Agricultural intensification in western Europe has caused a dramatic loss of grassland surfaces in farmlands, which have resulted in strong declines in grassland invertebrates, leading to cascade effects at higher trophic levels among consumers of invertebrates. Grasshoppers are important components of grassland invertebrate assemblages in European agricultural ecosystems, particularly as prey for bird species. Understanding how grasshopper populations are distributed in fragmented landscapes with low grassland availability is critical for both studies in biodiversity conservation and insect management. We assessed the range and strength of spatial autocorrelation for two grasshopper taxa (Gomphocerinae subfamily and Calliptamus italicus L.) across an intensive farmland in western France. Data from surveys carried out over 8 yr in 1,715 grassland fields were analyzed using geostatistics. Weak spatial patterns were observed at small spatial scales, suggesting important local effects of management practices on grasshopper densities. Spatial autocorrelation patterns for both grasshopper taxa were only detected at intermediate scales. For Gomphocerinae, the range of spatial autocorrelation varied from 802 to 2,613 m according to the year, depending both on grasshopper density and on grassland surfaces in the study site, whereas spatial patterns for the Italian locust were more variable and not related to grasshopper density or grassland surfaces. Spatial patterns in the distribution of Gomphocerinae supported our hypothesis that habitat availability was a major driver of grasshopper distribution in the landscape, and suggested it was related to density-dependent processes such as dispersal.

    The grasshoppers are strategic in the welfare of man and may constitute a major threat when its population is not checked. A study on the distribution of grasshoppers in open plots and farmlands was carried out within Calabar Metropolis between August to November, 2010. A total of 295 grasshoppers belonging to 11 species grouped under 3 families (Tettigoniidae, Acrididae and Pyrgomorphidae) were collected from 8 study locations. Grasshoppers were collected weekly from all study sites using sweep nets between 11 a.m. to 4 p.m. The collection was done using sweep nets between 11 a.m. to 4 p.m. when grasshoppers baked themselves under the sun. The percentage abundance of these species were Spathosterrium pygmaeum (16.27%), Tettigonia viridissima (11.86%), Catantops spissus (11.19%) Acridaturita sp. (10.17%), Gastrimargus acrididae (9.83%), Schistocerca nitens (9.49%), Tylopsis sp. (7.46%), Zonocerus variegatus (6.78%), Omocestus viridulus (6.10%), Scudderia mexicana (5.76%) and Zonocerus elegans (5.08%). Tettigonia viridissima and Acridaturita sp. were largely distributed as it occurred in 7 of 8 study sites while Scudderia mexicana was the least distributed, as it was reported in 3 sites only. The dominant grasshopper species in open plot was Spathosterrium pygmaeum (19%) in relative abundance and the least was Zonocerus variegatus (0.64%). Zonocerus variegatus was the dominant species in farmland (14%) in relative abundance and the least was Schistocerca nitens (4%). Chi-square test showed a high significant difference between the distribution of grasshoppers in open plots and farmlands (p grasshopper species composition were attributed to lizard predation and management practices such as grass cutting, fertilizer and pesticide applications. It was therefore concluded that species abundance and population of grasshoppers could be enhanced by minimizing human activities that interfere with land use.

  9. Supercooling capacity and cold hardiness of band-winged grasshopper eggs (Orthoptera: Acrididae).

    The band-winged grasshopper, Oedaleus asiaticus Bei-Bienko, is one of the most dominant and economically important grasshopper species in the steppe grasslands and farming-pastoral ecotone in northern China. It is a univoltine species and overwinters as eggs in soil. The cold hardiness of its eggs was examined in the laboratory. Water content in soil significantly affected the supercooling points (SCPs), water content and fat content of prediapause eggs. With the increase of water content in soil, the SCP, and water content of prediapause eggs rose whereas the fat content declined. There was a significant relationship between the SCP and water content or fat content of prediapause eggs. The SCPs of prediapause and diapause eggs varied from -7.6 to -28.4°C and the SCPs of eggs 30 d after oviposition could be divided into two groups. The means of high SCP group (-11.0 to -11.9°C) were much higher than those of low SCP group (-21.8 to -21.9°C), and the majority belonged to the latter (90.48-93.33%). The SCPs of prediapause eggs and early-diapause eggs 30 d after oviposition were significantly higher than those of deep-diapause eggs 60 d after oviposition. The survival rates of diapause eggs were significantly different among different temperature treatments. The survival rate was higher than 88% at greater than -20°C and declined significantly to 57% at -25°C, and suddenly dropped to zero at -30°C. The lower lethal temperature (Ltemp50) for 12 h exposure was -25.3°C and the lower lethal time (Ltime50) at -20°C was 32.8 d. As the mean SCPs of diapause eggs were similar to their Ltemp50, the SCP of eggs can be considered as a good indicator of cold hardiness for O. asiaticus and that this grasshopper is a freeze-intolerant insect. © The Author 2014.

  12. Understanding the genetic effects of recent habitat fragmentation in the context of evolutionary history: Phylogeography and landscape genetics of a southern California endemic Jerusalem cricket (Orthoptera: Stenopelmatidae: Stenopelmatus)

    Habitat loss and fragmentation due to urbanization are the most pervasive threats to biodiversity in southern California. Loss of habitat and fragmentation can lower migration rates and genetic connectivity among remaining populations of native species, reducing genetic variability and increasing extinction risk. However, it may be difficult to separate the effects of recent anthropogenic fragmentation from the genetic signature of prehistoric fragmentation due to previous natural geological and climatic changes. To address these challenges, we examined the phylogenetic and population genetic structure of a flightless insect endemic to cismontane southern California, Stenopelmatus 'mahogani' (Orthoptera: Stenopelmatidae). Analyses of mitochondrial DNA sequence data suggest that diversification across southern California began during the Pleistocene, with most haplotypes currently restricted to a single population. Patterns of genetic divergence correlate with contemporary urbanization, even after correcting for (geographical information system) GIS-based reconstructions of fragmentation during the Pleistocene. Theoretical simulations confirm that contemporary patterns of genetic structure could be produced by recent urban fragmentation using biologically reasonable assumptions about model parameters. Diversity within populations was positively correlated with current fragment size, but not prehistoric fragment size, suggesting that the effects of increased drift following anthropogenic fragmentation are already being seen. Loss of genetic connectivity and diversity can hinder a population's ability to adapt to ecological perturbations commonly associated with urbanization, such as habitat degradation, climatic changes and introduced species. Consequently, our results underscore the importance of preserving and restoring landscape connectivity for long-term persistence of low vagility native species.

  13. Shrinking wings for ultrasonic pitch production: hyperintense ultra-short-wavelength calls in a new genus of neotropical katydids (Orthoptera: Tettigoniidae.

    Fabio A Sarria-S

    Full Text Available This article reports the discovery of a new genus and three species of predaceous katydid (Insecta: Orthoptera from Colombia and Ecuador in which males produce the highest frequency ultrasonic calling songs so far recorded from an arthropod. Male katydids sing by rubbing their wings together to attract distant females. Their song frequencies usually range from audio (5 kHz to low ultrasonic (30 kHz. However, males of Supersonus spp. call females at 115 kHz, 125 kHz, and 150 kHz. Exceeding the human hearing range (50 Hz-20 kHz by an order of magnitude, these insects also emit their ultrasound at unusually elevated sound pressure levels (SPL. In all three species these calls exceed 110 dB SPL rms re 20 µPa (at 15 cm. Males of Supersonus spp. have unusually reduced forewings (<0.5 mm(2. Only the right wing radiates appreciable sound, the left bears the file and does not show a particular resonance. In contrast to most katydids, males of Supersonus spp. position and move their wings during sound production so that the concave aspect of the right wing, underlain by the insect dorsum, forms a contained cavity with sharp resonance. The observed high SPL at extreme carrier frequencies can be explained by wing anatomy, a resonant cavity with a membrane, and cuticle deformation.

    Paul J. Thibault

    2014-06-01

    Full Text Available Uso a distinção feita por Saussure entre relações associativas e sintagmáticas na langue como ponto de partida para um re-exame da relação entre memória e língua. Os comentários de Saussure sobre esta relação são escassos e fragmentados, e colocados nos relatos clássicos, hoje em dia em grande parte abandonados, dos primeiros neurologistas, como Broca e Wernicke, que viam a linguagem no cérebro como uma série de áreas corticais interconectadas que se presumia serem os repositórios dos processos neurofisiológicos da função da linguagem. Inspiro-me na idéia de Andy Clark (1993 de “motores associativos” para discutir como a coordenação associativa de itens linguísticos envolve (1 o potencial de evolução para explorar a lacuna entre o input ambiental bruto para o organismo e o input para redes neurais específicas; e (2 o potencial para o aprendiz da linguagem enquanto agente ativo de criar um pouco de seu próprio ambiente de aprendizagem. Examino então as maneiras de o princípio da coordenação associativa de diversas séries armazenadas na memória de longo prazo tornar possível e dar origem à análise e segmentação dos sintagmas linguísticos. Este desenvolvimento, por sua vez, possibilita a detecção da parte comum de diversos sintagmas de tal modo que eles podem ser substituídos por outros mais esquemáticos. O esquema linguístico resultante incorpora restrições funcionais no input de dados disponíveis para o aprendiz e, assim, serve como um dispositivo pedagógico, que eu chamo FUNÇÃO ENSINO. A teoria da Microgênese de Jason Brown (1988 juntamente com a explicação de Deacon (1989 para os fluxos duplamente centrípetos e centrífugos e de informação no cérebro fornecem a base para uma explicação mais coerente e completa da estrutura neural da linguagem: O enunciado é microgeneticamente elaborado conforme se desenrola de forma centrifuga ao longo de uma sequência de níveis neuro

    Full Text Available En este artículo se analizan, desde una perspectiva paradigmática de las ciencias, algunas de las contribuciones de dos de los más importantes lingüistas del siglo XX, Ferdinand de Saussure y Noam Chomsky. La tesis central que se sustenta aquí es que existe evidencia proveniente de estos aportes a favor de la consolidación de la Lingüística como una ciencia madura en el estudio de la estructura del lenguaje humano, y de una comunidad científica, cuyos orígenes dan cuenta de lo que podría llamarse la prehistoria de la lingüística. Se recurre, para este propósito, a una línea de argumentación centrada en algunos conceptos propuestos por Thomas Kuhn en su libro La Estructura de las Revoluciones Científicas.The author of the article analyzes some contributions of two of the most prominent linguists of the 20th century, Ferdinand de Saussure and Noam Chomsky, from a paradigmatic viewpoint of science. The main statement supported here is the evidence, yielded by these contributions, which confirms that linguistics is a mature science in the study of the structure of human language, and also, that there existed a scientific community whose origins account for what could be called the prehistory of linguistics. The author employs for this purpose an argumentative chain which is focused on some core concepts as proposed by Thomas Kuhn in his book La Estructura de las Revoluciones Científicas.

  3. Diverse Effects of a Seven-Year Experimental Grassland Fragmentation on Major Invertebrate Groups.

    Braschler, Brigitte; Baur, Bruno

    2016-01-01

    Habitat fragmentation is a major driver of biodiversity loss, but observed effects vary and may depend on the group examined. Time since fragmentation may explain some differences between taxonomical groups, as some species and thus species composition respond with a delay to changes in their environment. Impacts of drivers of global change may thus be underestimated in short-term studies. In our study we experimentally fragmented nutrient-poor dry calcareous grasslands and studied the response of species richness, individual density and species composition of various groups of invertebrates (gastropods, ants, ground beetles, rove beetles, orthoptera, spiders, woodlice) in 12 small (1.5 m * 1.5 m) and 12 large (4.5 m * 4.5 m) fragments and their corresponding control plots after 7 years. We further examined responses to fragmentation in relation to body size and habitat preferences. Responses to fragmentation varied between taxonomical groups. While spider species richness and individual density were lower in fragments, the opposite was true for an orthopteran species and woodlice. Species composition and β-diversity differed between fragments and control plots for some groups. However, the interaction treatment*plot size was rarely significant. Species with high occupancy rates in undisturbed control plots responded more negatively to the fragmentation, while species with large body size were relatively more abundant in fragments in some groups. No effect of the fragmentation was found for ants, which may have the longest lag times because of long-lived colonies. However, relationships between abundance and the species' preferences for environmental factors affected by edge effects indicate that ant diversity too may be affected in the longer-term. Our results show the importance of considering different groups in conservation management in times of widespread fragmentation of landscapes. While species richness may respond slowly, changes in abundance related to

    2012-06-01

    From 1998 to 2003, beetles and crickets infected with hairworms were collected from 4 localities within the Hanford Nuclear Site and the Hanford Reach National Monument, located in a shrub-steppe region of Washington State along the Columbia River. Infected hosts comprised 6 species of carabid beetles within 5 genera and 2 camel crickets within 1 genus; all are newly documented insect-nematomorph associations. A large proportion of the infected hosts (48%) were collected from a single site during a single collecting period. Of the 38 infected hosts, 32 contained a single worm, 4 hosts contained 2 worms, and 2 hosts contained 3 worms. Five of the hosts with multiple infections contained at least 1 male and 1 female worm. Camel crickets were infected with Neochordodes occidentalis while carabids were infected with an undescribed species of Gordionus . As the majority of hairworms are collected in the post-parasitic adult phase, host data and hairworm-arthropod associations remain poorly documented and our work adds new data to this area of nematomorph biology.

    Full Text Available Study of the toxicity of the crude acetone leaf extract of Euphorbia guyoniana Boiss. and Reut. (Euphorbiaceae in Schistocerca gregaria (Forskål, 1775 (Orthoptera-Acrididea Abstract-This study examines the effect by ingestion of leaf cabbage sprayed with crude acetone extract of Euphorbia guyoniana leaves harvested in the Algerian Sahara on some biological parameters of larvae L5 and adult of desert locusts. The ingestion of cabbage leaves soaked in acetone extract of this Saharan plant generates a 100% mortality in larvae L5 and 66,67% for adult. A significant reduction in food intake was observed in the treated population compared to the control population. It results in a loss of exceptional weight ranging from 26,93% in larvae L5 to 33,09% in adults. Difficulties and anomalies are observed in moulting 16,66% of larvae L5 fed with cabbage leaves soaked in leaf extract of E. guyoniana. Dissection of adult females of the lot processing allows the observation of body regression demonstrating the depressant action of this extract on ovocyte cycle in the desert locust.

    Full Text Available The LIFE project “MIPP” - Monitoring of Insects with Public Participation (11 NAT/IT/000252 is focused on selected insect species (five Coleoptera, three Lepidoptera, one Orthoptera, all included in the annexes II and IV of the Habitats Directive (HD 92/43/EEC. One important aim is a citizen science initiative where every person may become a citizen scientist and collect faunistic data on the above species throughout Italy. Another objective of the project MIPP is the development of standard methods for monitoring the conserva- tion status of the five target beetle species. One innovative method employed is a sniffer-dog (“Osmodog”, trained to find the rare and endangered hermit beetle, Osmoderma eremita, which lives in veteran, hollow trees. The dog detects the strong smell of mature peach produced by adult males and an odor produced by the larvae. Another objective of the project MIPP is the dissemination of topics such as HD, Natura 2000, importance of dead-wood, Life projects, insect monitoring and conservation.

    Abstract. Weather can be treated as an important factor in the nesting pattern of several solitary wasps species. Nesting pattern of wasp Monobia angulosa Saussure (Vespidae: Eumeninae was accessed in present study in the agricultural area of Mucugê-Ibicoara, Chapada Diamantina, Bahia, during an extended period of dry season. In here we also presented the first record of a natural nest in pre-existing cavities prior used by Xylocopa (Neoxylocopa cearensis Ducke (Apidae: Xylocopinae. For a description of the M. angulosa’s natural nest a single nest found in apple orchard (Malus domestica Borkh was used. For the nesting pattern study we used the trap nests technique with 25 points along the agricultural sampled area; traps were placed in remaining native vegetation. Each sample point was at least 4 km apart. Emerged in the laboratory a total of 19 females and 23 males for a total of 19 established nests, males emerged prior females. Unlike the horizontal trap nests, the natural one was built in vertical linear series and a wooden stake was used as a substrate. Nesting concentrated in the warmer months, between February and April, 2012, with very low precipitation, evidencing influence on nesting pattern of this species, probably due fast response to climatic changes.

  20. The Ursa Major supercluster

    Schuch, N.J.

    1983-01-01

    An optical and a radio survey have been carried out. The optical observations consist of a spectroscopic survey in which redshift data for cluster galaxies and optical identifications of radio sources were obtained with the 98-inch Isaac Newton telescope at the Royal Greenwich Observatory, and the 200-inch Hale telescope; the photographic survey in B, V and R colors was made with the 48-inch Schmidt telescope at Palomar. Some results on the galaxy distribution in the Ursa Major supercluster are briefly discussed. (Auth.)

  1. Securing Major Events

    Loeoef, Susanna

    2013-01-01

    When asked why the IAEA should provide nuclear security support to countries that organize large public events, Nuclear Security Officer Sophia Miaw answers quickly and without hesitation. ''Imagine any major public event such as the Olympics, a football championship, or an Expo. If a dirty bomb were to be exploded at a site where tens of thousands of people congregate, the radioactive contamination would worsen the effects of the bomb, increase the number of casualties, impede a rapid emergency response, and cause long term disruption in the vicinity,'' she said. Avoiding such nightmarish scenarios is the driving purpose behind the assistance the IAEA offers States that host major sporting or other public events. The support can range from a single training course to a comprehensive programme that includes threat assessment, training, loaned equipment and exercises. The type and scope of assistance depends on the host country's needs. ''We incorporate nuclear security measures into their security plan. We don't create anything new,'' Miaw said

  5. Do Biology Majors Really Differ from Non–STEM Majors?

    Cotner, Sehoya; Thompson, Seth; Wright, Robin

    2017-01-01

    Recent calls to action urge sweeping reform in science education, advocating for improved learning for all students—including those majoring in fields beyond the sciences. However, little work has been done to characterize the differences—if any exist—between students planning a career in science and those studying other disciplines. We describe an attempt to clarify, in broad terms, how non–STEM (science, technology, engineering, and mathematics) majors differ from life sciences majors, and how they are similar. Using survey responses and institutional data, we find that non–STEM majors are not unilaterally science averse; non–STEM majors are more likely than biology majors to hold misconceptions about the nature of science, yet they are not completely ignorant of how science works; non–STEM majors are less likely than biology majors to see science as personally relevant; and non–STEM majors populations are likely to be more diverse—with respect to incoming knowledge, perceptions, backgrounds, and skills—than a biology majors population. We encourage science educators to consider these characteristics when designing curricula for future scientists or simply for a well-informed citizenry. PMID:28798210

  11. Stenting of major airway constriction

    Wu Xiaomei

    2002-01-01

    Objective: To investigate the correlated issues in the stenting treatment of major airway constriction. Methods: Nineteen cases of major airway stenting procedure were studied retrospectively. The clinical choice of stents of different advantages or deficiencies were discussed. The importance of intravenous anesthesia supporting, life-parameters monitoring during the procedures and the prevention of complications were analysed. Results: Under intravenous and local anesthesia, 19 Wallstents had been successively placed and relieved 19 cases of major airway constrictions due to malignant or benign diseases (15 of tumors, 3 of tuberculosis, 1 of tracheomalacia). Intravenous anesthesia and life-parameters monitoring had made the procedures more safe and precise. Conclusions: Major airway stenting is an reliable method for relieving tracheobronchial stenosis; and intravenous anesthesia supporting and life-parameters monitoring guarantee the satisfactions of procedures

  12. Major hazards onshore and offshore

    1992-01-01

    This symposium continues the tradition of bringing together papers on a topic of current interest and importance in terms of process safety - in this case, Major Hazards Onshore and Offshore. Lord Cullen in his report on the Piper Alpha disaster has, in effect, suggested that the experience gained in the control of major hazards onshore during the 1980s should be applied to improve safety offshore during the 1990s. This major three-day symposium reviews what has been learned so far with regard to major hazards and considers its present and future applications both onshore and offshore. The topics covered in the programme are wide ranging and deal with all aspects of legislation, the application of regulations, techniques for evaluating hazards and prescribing safety measures in design, construction and operation, the importance of the human factors, and recent technical developments in protective measures, relief venting and predicting the consequences of fires and explosions.

    The major disruption in a cylindrical tokamak is investigated by using the multi-helicity code, and the destabilization of the 3/2 mode by the mode coupling with the 2/1 mode is confirmed. The evolution of the magnetic field topology caused by the major disruption is studied in detail. The effect of the internal disruption on the 2/1 magnetic island width is also studied. The 2/1 magnetic island is not enhanced by the flattening of the q-profile due to the internal disruption. (author)

  7. Distance majorization and its applications.

    Chi, Eric C; Zhou, Hua; Lange, Kenneth

    2014-08-01

    The problem of minimizing a continuously differentiable convex function over an intersection of closed convex sets is ubiquitous in applied mathematics. It is particularly interesting when it is easy to project onto each separate set, but nontrivial to project onto their intersection. Algorithms based on Newton's method such as the interior point method are viable for small to medium-scale problems. However, modern applications in statistics, engineering, and machine learning are posing problems with potentially tens of thousands of parameters or more. We revisit this convex programming problem and propose an algorithm that scales well with dimensionality. Our proposal is an instance of a sequential unconstrained minimization technique and revolves around three ideas: the majorization-minimization principle, the classical penalty method for constrained optimization, and quasi-Newton acceleration of fixed-point algorithms. The performance of our distance majorization algorithms is illustrated in several applications.

  8. Neurobiology of Major Depressive Disorder

    Rosa Villanueva

    2013-01-01

    Full Text Available We survey studies which relate abnormal neurogenesis to major depressive disorder. Clinically, descriptive gene and protein expression analysis and genetic and functional studies revised here show that individual alterations of a complex signaling network, which includes the hypothalamic-pituitary-adrenal axis; the production of neurotrophins and growth factors; the expression of miRNAs; the production of proinflammatory cytokines; and, even, the abnormal delivery of gastrointestinal signaling peptides, are able to induce major mood alterations. Furthermore, all of these factors modulate neurogenesis in brain regions involved in MDD, and are functionally interconnected in such a fashion that initial alteration in one of them results in abnormalities in the others. We highlight data of potential diagnostic significance and the relevance of this information to develop new therapeutic approaches. Controversial issues, such as whether neurogenesis is the basis of the disease or whether it is a response induced by antidepressant treatments, are also discussed.

    Full Text Available Described from the steppe zones north of the Black Sea, Caucasus, and central Asia, Gryllotalpa stepposa Zhantiev was recently recorded from a few localities in Greece, R. Macedonia, and Bulgaria. In May 2015, several specimens were collected from Ivrinezu Mare in Romania, which suggested a continuous distribution area of the species, stretching from the central Balkans to central Asia. Thus, to reveal its actual range of occurrence, a survey of several Orthoptera collections became mandatory and, as expected, a large number of misidentified specimens of Gryllotalpa stepposa were discovered, providing new data on the species distribution in south-eastern Europe, including also the first records of this mole cricket in Serbia and Hungary. Here a full locality list is presented of this species west of Ukraine and Moldova and the current geographic distribution of the genus Gryllotalpa in the Balkans is revised. A key for distinguishing the mole crickets in south-eastern Europe and a distribution map for this region are presented.

    Full Text Available Reduction of effective doses of insecticide against desert locust (Schistocerca gregaria Forskål, 1775: Orthoptera, Acrididae nymphs using phenylacetonitrile. In order to reduce the amount of insecticides used during a locust upsurge, phenylacetonitrile (PAN was tested in 2007 and 2008, in the Niamey area (Niger. PAN was used, on the one hand, in topical applications on third stage nymphs (L3 of the desert locust, alone or in combination with reduced amounts of various insecticides (lambda-cyhalothrin, malathion, chlorpyrifos-ethyl. In addition, experiments were carried out in semi-natural conditions, in field enclosures, and also on third stage nymphs of the desert locust. Insecticides were each applied at the recommended dose and at half of that dose with the addition or not of phenylacetonitrile. All topical applications of insecticides led to the total mortality of the nymphs within 1 to 24 h; the use of PAN alone caused a mortality rate of no higher than 18% within 120 h. In the field enclosures, mortality rates for the desert locust nymphs were the same both with the recommended doses and with half of the dose with the addition of 10 ml of PAN·ha-1. Results indicate that the addition of small quantities of phenylacetonitrile could make it possible to decrease by half the quantities of insecticides used in the control of desert locust nymphs, while preserving the same effectiveness.

    Sears, P.M.

    1979-08-01

    The manual provides technical assistance to existing or prospective vanpool sponsors. It is designed to help them promote vanpooling in its three major approaches: employer sponsored, third party sponsored, and driver owned and operated. The first chapter is an overview of vanpooling and a second chapter, on vanpool marketing, is addressed to ridesharing coordinators and others whose responsibilities include the promotion of vanpooling. Some fact sheets on the three approaches provide convenient summaries of the needs and opportunities of each approach and suggest solutions to practical problems likely to be encountered in starting new vanpool programs.

  14. Majority rule on heterogeneous networks

    Lambiotte, R

    2008-01-01

    We focus on the majority rule (MR) applied on heterogeneous networks. When the underlying topology is homogeneous, the system is shown to exhibit a transition from an ordered regime to a disordered regime when the noise is increased. When the network exhibits modular structures, in contrast, the system may also exhibit an asymmetric regime, where the nodes in each community reach an opposite average opinion. Finally, the node degree heterogeneity is shown to play an important role by displacing the location of the order-disorder transition and by making the system exhibit non-equipartition of the average spin

    A disaster can be defined as an event, or a series of events, in which a large number of people is adversely affected by a single cause. This definition includes man-made accidents, like that at Chernobyl, as well as the natural disasters that insurance companies are sometimes pleased to describe as Acts of God. In 1986 alone, 12,000 people died and 2.2 million were made homeless by 215 major accidents or disasters. The nature of risk is examined in this paper. (author)

  16. Reduced recruitment in Hyalella azteca (Saussure, 1858) exposed to copper.

    Othman, M Shuhaimi; Pascoe, David

    2002-09-01

    Neonates of the amphipod Hyalella azteca were exposed for a 35-day period in the laboratory to a range of copper concentrations, nominally 18 microg/l, 40 microg/l, 70 microg/l and 260 microg/l. The reproductive status of the population was assessed by recording recruitment, the number of precopulatory pairs and number of gravid females. At the end of the experiment, the body lengths of individuals were measured using image analysis. There was a significant decrease in the final population size of H. azteca with increasing copper concentration and compared with the control. Copper significantly reduced recruitment of juveniles and length composition of the final population and there was also a trend toward reduced precopula number with increasing copper concentrations.

    2000-04-01

    As a new millennium has started, there are active movements developing a basic paradigm of vision and policy over a nation-wide to prepare changes actively. For the environmental sector, it is possible to live in a pleasant environment if everyone prepare and work together like dealing with Y2K problem. With a goal of being an environmentally advanced country in the early new millennium, it is planned to improve a basic life environment such as water and air and to promote an advanced environmental management policy for showing results of its reform in 2000. Therefore, it examines environmental management circumstances and a direction of environmental policy first and it discusses more about major environmental policy related to petroleum industry. 7 tabs.

    not been consistent. METHOD: We examined neuroticism, extraversion and perceived stress in 88 fully remitted depressed patients with a mean age of 60 years and with a history of hospitalization for major depressive disorder. Patients were divided into those with onset after and those with onset before 50......BACKGROUND: The personality trait of neuroticism is strongly related to depression, but depression is etiologically heterogeneous. Late-onset depression (LOD) may be more closely related to vascular factors, and previous studies of neuroticism in LOD versus early-onset depression (EOD) have...... age of onset and neuroticism was confirmed in analyses based on age of depression onset as a continuous variable. CONCLUSION: Neuroticism may be an etiological factor in EOD but not or less so in LOD. This finding contributes to the growing evidence for etiological differences between early- and late...

    Many causes including the chronicity of disease, burden of treatment modalities, morbidities, and the expectation of early death resulting from the disease complications, may lead to psychosocial burden in Thalassemia Major (TM) patients. A total of 38 patients with TM and their mothers were recruited to evaluate the psychosocial burden as well as to disclose whether the psychological status of the patients contribute to the compliance with the therapy or to the contrary. Demographic and disease variables were obtained. Child Behavior Check-list (CBCL) was completed by the mothers of the patients. A detailed psychiatric interview based on the 4th edition of the Diagnostic and Statistical Manual diagnostic criteria was performed for each patient. Symptom Distress Checklist 90 (SCL-90) scale was given to all mothers for evaluating their psychopathology. Although CBCL scores remained between the normal ranges, desferrioxamine mesylate (DFO)-compliant patients and the patients with lower ferritin values had significantly higher scores. A total of 24% of the patients had a psychiatric diagnosis including major depression, anxiety disorder, tic disorder, and enuresis nocturnal. The psychiatric diagnosis was significantly higher in the patients who were compliant with desferrioxamine compared with the non-compliant group (P = 0.007). The SCL-90 scores indicated that the mothers who had a child with good adherence to DFO had higher scale scores than the mothers with a poor adherent child. The increase risk of psychosocial and behavioral problems in thalassemics and their parents indicated the importance of a lifelong psychosocial support for the prevention of mental health issues. The patients and their parents, who were more conscious of the illness, were more worried but more compliant with the therapy and need stronger psychiatric support.

  2. Thalassaemia major and the heart

    J. Malcolm Walker

    2013-03-01

    Full Text Available Disorders of haemoglobin synthesis are the commonest monogenetic disorders worldwide. When first described, thalassaemia was universally fatal in childhood, but after the adoption of regular blood transfusion survival until early teenage and adulthood was to be expected. At that stage in the life of these affected individuals organ failure followed, due to accumulated iron, for which the human has no excretory capacity. Principal amongst the tissues affected by iron overload is the heart and even to the present day, heart disease accounts for the overwhelming majority of premature deaths in this population. Managing transfusion derived iron overload was the next hurdle for clinicians and the families of the patients. For nearly four decades the only available treatment was the demanding regime of parenteral chelation therapy, required on a daily basis, to achieve growth, development and survival with limited or no organ damage. Despite the adoption of these treatment strategies the outlook for thalassaemia patients remained poor, with a 30% to 40% mortality occurring between late teenage and 30 years of age, even in well organised health care systems, such as in the UK, where regular transfusion and desferioxamine treatment were readily available. This dreadful early mortality, largely as a consequence of myocardial iron overload, (1,2 is now improving so that in the UK and other developed nations, heart failure in thalassaemic patients has become uncommon and premature death a much rarer tragedy. This editorial reviews, from a personal viewpoint of a cardiologist involved in the care of these patients for the last 20 years, the progress in the management of the cardiovascular complications of thalassaemia major (TM, which has followed better techniques of identifying those thalassaemic individuals at greatest risk, improved chelation strategies making best use of the three chelating agents that are now available and improved co

  3. Tilecal meets two major milestones

    Cavalli-Sforza, M.

    Over the last two months the Tile Calorimeter passed not one but two major milestones. In early May, the last of the 64 modules that make up one of the two Extended Barrels arrived at CERN from IFAE-Barcelona, equipped with optical components and tested. And during the Overview Week in Clermont-Ferrand, the last of the 64 Barrel modules, mechanically assembled, arrived from JINR-Dubna. Just a brief reminder: the ATLAS Tile Calorimeter is composed of 3 cylinders ("barrels") of steel, scintillating tiles and optical fibers, altogether about 12 m long, with an outer diameter of 8.4 m, and weighing about 2700 tons. The central cavity will contain the Liquid Argon cryostats, and the whole calorimetry system will measure the direction and energy of jets produced at the LHC, as well as the missing transverse energy, which as everyone knows is one of the telltale signals of new and exciting physics. Each of the three cylinders is divided azimuthally into 64 modules - much like the slices of an orange. The modules ar...

  4. [Oromaxillofacial changes in thalassemia major].

    De Mattia, D; Pettini, P L; Sabato, V; Rubini, G; Laforgia, A; Schettini, F

    1996-01-01

    Sixty patients (31 male and 29 female) with thalassemia major, aged between 6 and 26 years, 18 of which were splenectomized, were observed in this study evaluating the oro-maxillo-facial alterations and correlating them to transfusion indexes, serum ferritin levels, splenectomy and age. For each patient a haematologic and odontostomatologic card was filed with a view to report the medical and clinical history regarding: the haematologic picture, the prevention of caries and parodontal disease, the facies characteristics, the odonto-stomatologic examination, the orthodontic diagnosis, the skull X-rays and the orthopantomography. Poor oral hygiene as well as misknowledge of prevention were generally observed. All the patients showed carious lesions but most of them had never seen a dentist for therapy. The disharmonious growth of splanchnocranium, with the enlargement of the jaw and of its alveolar process, induced by the bone marrow hyperplasia, produced various and serious malocclusion stages (Angle's II class, deep bite, open bite), gnathologic alterations, hypodiaphanous paranasal sinuses and orbital hypertelorism, with a typical oriental-like facies. Malocclusion and the poor oral hygienic conditions determined the occurrence of marginal gingivitis, mainly localized at the level of the lower frontal teeth. In only 3 patients the oral mucous membrane was pale and atrophic. During this investigation agenesia and dental retention were reported in 30% and in 26% of the examined cases respectively, while no patients had supernumerary teeth. Tooth volume, position and shape abnormalities rarely occurred. Only in two patients was enamel hypoplasia described. The caries frequency greatly varied in number and in degree. Only five patients did not show any carious lesions. The caries index (DMF) for the permanent teeth calculated in all the 60 subjects was 5, 12 +/- 4.76. By utilizing Spearman's rank test the number of teeth with caries in the permanent dentition (DFM

    Full Text Available El desarrollo, relativamente reciente, de dos tecnologías de análisis de patrones espaciales, como son los Sistemas de Información Geográfica (SIG y la teledetección, ha abierto nuevos caminos en estudios sobre entomología aplicada. Los SIG han facilitado a entomólogos y ecólogos el análisis de aquellos patrones espaciales complejos que presentan una variación temporal. Tal vez uno de los principales usos de los SIG dentro de la entomología aplicada está vinculado con el estudio de las relaciones entre las explosiones poblacionales de insectos ("outbreaks" y las variables ambientales. Las explosiones poblacionales de acridios, tanto de especies de langostas como de tucuras, son ejemplos típicos de la dinámica espacial de insectos que ocurre a gran escala y que se ve afectada por condiciones locales que varían en el tiempo. Debido a estas características este grupo de insectos plaga ha sido objeto de análisis y aplicación de estas nuevas herramientas. En este trabajo se brindan los conceptos básicos de los SIG y la teledetección y se lleva a cabo una revisión de su utilidad en entomología aplicada, utilizando los estudios de su aplicación en acridios como ejemplo.The advent of Geographic Information Systems (GIS and remote sensing has made the analysis of complex spatial patterns an attainable reality for entomologists and ecologists. Within the general area of applied insect entomology, perhaps one of the major uses of GIS is the one that relates insect outbreaks to environmental features of the landscape. Outbreaks of grasshoppers and locusts are typical examples of large-scale spatial dynamics that are affected by local conditions that fluctuate with time. Factors affecting the numerical fluctuations in grasshopper and locust populations are usually variables that have both spatial and temporal characteristics and thus can be mapped and incorporated into a GIS. Following a brief introduction to GIS and remote sensing, a

  9. The Prototypical Majority Effect Under Social Influence.

    Koriat, Asher; Adiv-Mashinsky, Shiri; Undorf, Monika; Schwarz, Norbert

    2018-05-01

    Majority views are reported with greater confidence and fluency than minority views, with the difference increasing with majority size. This Prototypical Majority Effect (PME) was attributed generally to conformity pressure, but Koriat et al. showed that it can arise from the processes underlying decision and confidence independent of social influence. Here we examined the PME under conditions that differ in social influence. In Experiment 1, a robust PME emerged in the absence of information about the majority views, but the provision sof that information increased the choice of the majority view and magnified the PME. In Experiment 2, a PME emerged in a minority-biased condition that misled participants to believe that the majority view was the minority view, but the PME was stronger in a majority-biased condition. The results were discussed in terms of a dual-process view: The PME observed under social influence may contain externally driven and internally driven components.

  10. Majorization arrow in quantum-algorithm design

    Latorre, J.I.; Martin-Delgado, M.A.

    2002-01-01

    We apply majorization theory to study the quantum algorithms known so far and find that there is a majorization principle underlying the way they operate. Grover's algorithm is a neat instance of this principle where majorization works step by step until the optimal target state is found. Extensions of this situation are also found in algorithms based in quantum adiabatic evolution and the family of quantum phase-estimation algorithms, including Shor's algorithm. We state that in quantum algorithms the time arrow is a majorization arrow

  18. Inequalities theory of majorization and its applications

    Olkin, Ingram

    1980-01-01

    Although they play a fundamental role in nearly all branches of mathematics, inequalities are usually obtained by ad hoc methods rather than as consequences of some underlying ""theory of inequalities."" For certain kinds of inequalities, the notion of majorization leads to such a theory that is sometimes extremely useful and powerful for deriving inequalities. Moreover, the derivation of an inequality by methods of majorization is often very helpful both for providing a deeper understanding and for suggesting natural generalizations.Anyone wishing to employ majorization as a tool in applicati

    2018-05-01

    Full Text Available Cereal crops have played major roles in addressing food security issues in Nepal. In recent years there have been fluctuations in crop production and demands situations due to various reasons. Thus, the present study aims to analyze the dynamics of major cereals productivity in Nepal from 1995 to 2014. Focus group discussions were done in mid-hills and tarai of Nepal in 2015. Percentage change, compound growth rate, annual rate of change, coefficient of variation, instability index were calculated to analyze results. The result shows that the area, production and productivity of major cereals had an increasing trend over the study period. The major factors contributing on productivity increase in cereal crops were irrigation facilities, use of improved and hybrid seeds, chemical fertilizer and better technical knowhow among the farmers. For effective adoption of research outputs to improve the productivity emphasis should also be given on promotion of public private partnership (PPP in research and development.

  9. Characterizing the epistemological development of physics majors

    Elizabeth Gire

    2009-02-01

    Full Text Available Students in introductory physics courses are likely to have views about physics that differ from those of experts. However, students who continue to study physics eventually become experts themselves. Presumably these students either possess or develop more expertlike views. To investigate this process, the views of introductory physics students majoring in physics are compared with the views of introductory physics students majoring in engineering. In addition, the views of physics majors are assessed at various stages of degree progress. The Colorado learning attitudes about science survey is used to evaluate students’ views about physics, and students’ overall survey scores and responses to individual survey items are analyzed. Beginning physics majors are significantly more expertlike than nonmajors in introductory physics courses, and this high level of sophistication is consistent for most of undergraduate study.

  12. Disturbances in equilibrium function after major earthquake.

    Honma, Motoyasu; Endo, Nobutaka; Osada, Yoshihisa; Kim, Yoshiharu; Kuriyama, Kenichi

    2012-01-01

    Major earthquakes were followed by a large number of aftershocks and significant outbreaks of dizziness occurred over a large area. However it is unclear why major earthquake causes dizziness. We conducted an intergroup trial on equilibrium dysfunction and psychological states associated with equilibrium dysfunction in individuals exposed to repetitive aftershocks versus those who were rarely exposed. Greater equilibrium dysfunction was observed in the aftershock-exposed group under conditions without visual compensation. Equilibrium dysfunction in the aftershock-exposed group appears to have arisen from disturbance of the inner ear, as well as individual vulnerability to state anxiety enhanced by repetitive exposure to aftershocks. We indicate potential effects of autonomic stress on equilibrium function after major earthquake. Our findings may contribute to risk management of psychological and physical health after major earthquakes with aftershocks, and allow development of a new empirical approach to disaster care after such events.

    2013-12-01

    Full Text Available Objective: To study the insertion of the pectoralis major tendon to the humerus, through knowledge of its dimensions in the coronal and sagittal planes. Methods: Twenty shoulders from 10 cadavers were dissected and the pectoralis major tendon insertion on the humerus was identified and isolated. The dimensions of its "footprint" (proximal to distal and medial to lateral borders and the distance from the top edge of the pectoralis major tendon to apex of the humeral head structures were measured. Results: The average proximal to distal border length was 80.8 mm (range: 70 -90 and the medial-to-lateral border length was 6.1 mm (5 -7. The average distance (and range from the apex of the pectoralis major tendon to the humeral head was 59.3 mm. Conclusions: We demonstrate that the insertion of the pectoralis major tendon is laminar, and the pectoralis major tendon has an average footprint height and width of 80.8 mm and 6.1 mm, respectively.

    1995-10-09

    Complex segregation analyses were conducted on families of bipolar I and bipolar II probands to delineate the mode of inheritance. The probands were ascertained from consecutive referrals to the Mood Disorder Service, University Hospital, University of British Columbia and diagnosed by DSM-III-R and Research Diagnostic Criteria. Data were available on over 1,500 first-degree relatives of the 186 Caucasian probands. The purpose of the analyses was to determine if, after correcting for age and birth cohort, there was evidence for a single major locus. Five models were fit to the data using the statistical package SAGE: (1) dominant, (2) recessive, (3) arbitrary mendelian inheritance, (4) environmental, and (5) no major effects. A single dominant, mendelian major locus was the best fitting of these models for the sample of bipolar I and II probands when only bipolar relatives were defined as affected (polygenic inheritance could not be tested). Adding recurrent major depression to the diagnosis {open_quotes}affected{close_quotes} for relatives reduced the evidence for a major locus effect. Our findings support the undertaking of linkage studies and are consistent with the analyses of the National Institutes of Mental Health (NIMH) Collaborative Study data by Rice et al. and Blangero and Elston. 39 refs., 4 tabs.

  18. The major tokamak distruption in cylindrical plasma

    Choi, Jeong Sik; Choi, Eun Ha; Choi, Duk In

    1986-01-01

    The mechanism of the major disruption in tokamak plasma which involves the nonlinear interaction of tearing models is numerically studied in two and three dimensional formulations. In this study, it is found that in the two dimensional case with a flattened current density profile the magnetic islands of the m=2; n=1 mode do not saturate nonlinearly and but strongly interact with the limiter. Thus it is suggested that the helical perturbation of the m=2;n=1 mode plays the dominant role in the major disruption. We also show that the m=2;n=1 mode nonlinearly destablizes other tearing modes, especially the m=3;n=2 mode, from the nonlinear coupling of different helicities as also shown in other studies. The plasma extends across the plasma cross section, and the plasma core shifts inward along the major radius during the major disruption. The numerical result for the major disruption time measured using the nonlinear 3-D procedure for the initial value problem with PLT parameters is about 450 μsec which agrees reasonably well with the experimental value of 500 μsec.

  20. Major dealers' expert power in distribution channels

    Richard Chinomona

    2011-06-01

    Full Text Available The importance of major dealers’ expertise in distribution channels and effects on exchange relations is widely acknowledged by many SMEs in Africa and yet there seem to be a paucity of research on this matter. To address this dearth, the current study attempts to examine the impact of major dealers’ expert power on SME manufacturers’ channel cooperation and the mediating influence of their trust, relationship commitment and satisfaction. The conceptualized model and five hypotheses are empirically validated using a sample of 452 manufacturing SMEs in Zimbabwe. The findings indicate that major dealers’ expert power may influence SME manufacturers’ trust, relationship commitment, relationship satisfaction and channel cooperation in a significant way. Managerial implications of the research findings are provided.

  9. Minerals in thalassaemia major patients: An overview.

    Ozturk, Zeynep; Genc, Gizem Esra; Gumuslu, Saadet

    2017-05-01

    Thalassaemia major (TM) is a hereditary blood disease characterised by reduced or absent production of beta globin chains. Erythrocyte transfusions are given to raise the haemoglobin level in patients with thalassaemia major. However, transfusions have been related to increased risk of iron overload and tissue damage related to excess iron. Both elevated oxidative stress due to iron overload and increased hemolysis lead to over utilisation of minerals required for antioxidant enzymes activities. Iron chelators have been used to prevent iron overload in thalassaemia major patients, but these chelators have the possibility of removing minerals from the body. Thalassaemia patients are more at risk for mineral deficiency because of increased oxidative stress and iron chelation therapies. Growth and maturational delay, cardiomyopathy, endocrinopathies and osteoporosis are the complications of thalassaemia. Minerals may play a particular role to prevent these complications. In the current review, we provide an overview of minerals including zinc (Zn), copper (Cu), selenium (Se), magnesium (Mg) and calcium (Ca) in thalassaemia major patients. We, also, underline that some complications of thalassaemia can be caused by an increased need for minerals or lack of the minerals. Copyright © 2017 Elsevier GmbH. All rights reserved.

  1. Exploring Pair Programming Benefits for MIS Majors

    April H. Reed

    2016-12-01

    Full Text Available Pair programming is a collaborative programming practice that places participants in dyads, working in tandem at one computer to complete programming assignments. Pair programming studies with Computer Science (CS and Software Engineering (SE majors have identified benefits such as technical productivity, program/design quality, academic performance, and increased satisfaction for their participants. In this paper, pair programming is studied with Management Information Systems (MIS majors, who (unlike CS and SE majors taking several programming courses typically take only one programming course and often struggle to develop advanced programming skills within that single course. The researchers conducted two pair programming experiments in an introductory software development course for MIS majors over three semesters to determine if pair programming could enhance learning for MIS students. The program results, researchers’ direct observations, and participants’ responses to a survey questionnaire were analyzed after each experiment. The results indicate that pair programming appears to be beneficial to MIS students’ technical productivity and program design quality, specifically the ability to create programs using high-level concepts. Additionally, results confirmed increased student satisfaction and reduced frustration, as the pairs worked collaboratively to produce a program while actively communicating and enjoying the process.

    Full Text Available Abstract. Until recently, Penthaleus major (Dugès has not been recognized as an economically significant pest for the cereal crops. After climatic changes, its population began to grow and inflict damages around the world. The aim of this study was to investigate its distribution in Bulgaria and establish whether it presents a danger to the cereal crops. In the autumn of 2015 and the spring of 2016, a monitoring survey was conducted to establish Penthaleus major (Dugès with the cereal crops in Bulgaria. Over 60 sowed fields were investigated from all around the country. Samples were taken to identify the pest. It was established that Penthaleus major (Dugès inflicted harm to the wheat in north-eastern (12-14 mites per stem and south-eastern Bulgaria (6-8 mites per stem. Its density was under the threshold of economic harm. There was not found infestation of barley, rye, oat and triticale. On the field boundaries bordering the areas attacked by the mite were reported the following weeds: Capsella bursa pastoris (L. Medic, Descurania sophia (L.

  1. Sex segregation in undergraduate engineering majors

    Litzler, Elizabeth

    Gender inequality in engineering persists in spite of women reaching parity in college enrollments and degrees granted. To date, no analyses of educational sex segregation have comprehensively examined segregation within one discipline. To move beyond traditional methods of studying the long-standing stratification by field of study in higher education, I explore gender stratification within one field: engineering. This dissertation investigates why some engineering disciplines have a greater representation of women than other engineering disciplines. I assess the individual and institutional factors and conditions associated with women's representation in certain engineering departments and compare the mechanisms affecting women's and men's choice of majors. I use national data from the Engineering Workforce Commission, survey data from 21 schools in the Project to Assess Climate in Engineering study, and Carnegie Foundation classification information to study sex segregation in engineering majors from multiple perspectives: the individual, major, institution, and country. I utilize correlations, t-tests, cross-tabulations, log-linear modeling, multilevel logistic regression and weighted least squares regression to test the relative utility of alternative explanations for women's disproportionate representation across engineering majors. As a whole, the analyses illustrate the importance of context and environment for women's representation in engineering majors. Hypotheses regarding hostile climate and discrimination find wide support across different analyses, suggesting that women's under-representation in certain engineering majors is not a question of choice or ability. However, individual level factors such as having engineering coursework prior to college show an especially strong association with student choice of major. Overall, the analyses indicate that institutions matter, albeit less for women, and women's under-representation in engineering is not

  2. Distortion product otoacoustic emissions in college music majors and nonmusic majors

    Rebecca L. Warner Henning

    2016-01-01

    Full Text Available The presence and absence of distortion product otoacoustic emissions (DPOAEs as well as DPOAE amplitudes were compared between college music majors and a control group of nonmusic majors. Participants included 28 music majors and 35 nonmusic majors enrolled at a university with ages ranging from 18-25 years. DPOAEs and hearing thresholds were measured bilaterally on all the participants. DPOAE amplitudes were analyzed at the following f2 frequencies: 1,187 Hz, 1,500 Hz, 1,906 Hz, 2,531 Hz, 3,031 Hz, 3812 Hz, 4,812 Hz, and 6,031 Hz. Significantly more music majors (7/28 than nonmusic majors (0/35 exhibited absent DPOAEs for at least one frequency in at least one ear. Both groups of students reported similar histories of recreational and occupational noise exposures that were unrelated to studying music, and none of the students reported high levels of noise exposure within the previous 48 h. There were no differences in audiometric thresholds between the groups at any frequency. At DPOAE f2 frequencies from 3,031 Hz to 6,031 Hz, nonsignificantly lower amplitudes of 2-4 dB were seen in the right ears of music majors versus nonmajors, and in the right ears of music majors playing brass instruments compared to music majors playing nonbrass instruments. Given the greater prevalence of absent DPOAEs in university music majors compared to nonmusic majors, it appears that early stages of cochlear damage may be occurring in this population. Additional research, preferably longitudinal and across multiple colleges/universities, would be beneficial to more definitively determine when the music students begin to show signs of cochlear damage, and to identify whether any particular subgroups of music majors are at a greater risk of cochlear damage.

  3. Review of major plutonium pyrochemical technology

    Moser, W.S.; Navratil, J.D.

    1983-01-01

    The past twenty years have seen significant growth in the development and application of pyrochemical technology for processing of plutonium. For particular feedstocks and specific applications, non-aqueous high-temperature processes offer key advantages over conventional hydrometallurgical systems. Major processes in use today include: (1) direct oxide reduction for conversion of PuO 2 to metal, (2) molten salt extraction for americium removal from plutonium, (3) molten salt electrorefining for Pu purification, and (4) hydriding to remove plutonium from host substrates. This paper reviews current major pyrochemical processes from the classical calcination-hydrofluorination-bomb reduction sequence through new techniques under development. Each process is presented and brief descriptions of production equipment are given. 47 references, 5 figures

  4. A student's guide to Einstein's major papers

    Kennedy, Robert E

    2012-01-01

    Our understanding of the physical universe underwent a revolution in the early twentieth century - evolving from the classical physics of Newton, Galileo, and Maxwell to the modern physics of relativity and quantum mechanics. The dominant figure in this revolutionary change was Albert Einstein. In a single year, 1905, Einstein produced breakthrough works in three areas of physics: on the size and the effects of atoms; on the quantization of the electromagnetic field; and on the special theory of relativity. In 1916 he produced a fourth breakthrough work, the general theory of relativity. A Student's Guide to Einstein's Major Papers focuses on Einstein's contributions, setting his major works into their historical context, and then takes the reader through the details of each paper, including the mathematics. This book helps the reader appreciate the simplicity and insightfulness of Einstein's ideas and how revolutionary his work was, and locate it in the evolution of scientific thought begun by the ancient...

  5. Major gene mutations and domestication of plants

    Ashri, A.

    1989-01-01

    From the approximately 200,000 species of flowering plants known, only about 200 have been domesticated. The process has taken place in many regions over long periods. At present there is great interest in domesticating new species and developing new uses for existing ones in order to supply needed food, industrial raw materials, etc. It is proposed that major gene mutations were important in domestication; many key characters distinguishing cultivated from related wild species are controlled by one or very few major genes. The deliberate effort to domesticate new species requires at least the following: identification of needs and potential sources, establishment of suitable niches, choice of taxa to be domesticated, specification of the desired traits and key characters to be modified, as well as the potential role of induced mutations.

  10. Major Brazilian gold deposits - 1982 to 1999

    Thorman, Charles H.; DeWitt, Ed; Maron, Marcos A.; Ladeira, Eduardo A.

    2001-07-01

    Brazil has been a major but intermittent producer of gold since its discovery in 1500. Brazil led the world in gold production during the 18th and early 19th centuries. From the late 19th century to the late 20th century, total mining company and garimpeiro production was small and relatively constant at about 5 to 8 t/year. The discovery of alluvial deposits in the Amazon by garimpeiros in the 1970s and the opening of eight mines by mining companies from 1983 to 1990 fueled a major boom in Brazil's gold production, exceeding 100 t/year in 1988 and 1989. However, garimpeiro alluvial production decreased rapidly in the 1990s, to about 10 t/year by 1999. Company production increased about tenfold from about 4 t/year in 1982 to 40 t in 1992. Production from 1992 to the present remained relatively stable, even though several mines were closed or were in the process of closing and no new major mines were put into production during that period. Based on their production history from 1982-1999, 17 gold mines are ranked as major (>20 t) and minor (3-8 t) mines. From 1982-1999, deposits hosted in Archean rocks produced 66% of the gold in Brazil, whereas deposits in Paleoproterozoic and Neoproterozoic rocks accounted for 19% and 15%, respectively. Deposits in metamorphosed sedimentary rocks, especially carbonate-rich rocks and carbonate iron-formation, yielded the great bulk of the gold. Deposits in igneous rocks were of much less importance. The Archean and Paleoproterozoic terranes of Brazil largely lack base-metal-rich volcanogenic massive sulfide deposits, porphyry deposits, and polymetallic veins and sedimentary exhalative deposits. An exception to this is in the Carajás Mineral Province.

  12. Statistical mechanics of the majority game

    Kozlowski, P; Marsili, M

    2003-01-01

    The majority game, modelling a system of heterogeneous agents trying to behave in a similar way, is introduced and studied using methods of statistical mechanics. The stationary states of the game are given by the (local) minima of a particular Hopfield-like Hamiltonian. On the basis of replica symmetric calculations, we draw the phase diagram, which contains the analogue of a retrieval phase. The number of metastable states is estimated using the annealed approximation. The results are confronted with extensive numerical simulations

  16. Plasma fibronectin in patients undergoing major surgery

    Sallam, M.H.M.

    2003-01-01

    Plasma fibronectin in patients undergoing major surgery had been determined before and after operation. The study was done on 15 patients and 15 normal healthy individuals. The study revealed that patients subjected to major operation, their fibronectin level was normal before operation followed by reduction one day post-operation. After one week, fibronectin level raised again nearly to the pre-operations levels. The probable mechanisms of fibronectin in healing processes were discussed. Fibronectin (FN) is a family of structurally and immunologically related high molecular weight glycoproteins that are present in many cell surfaces, in extracellular fluids, in connective tissues and in most membranes. Interaction with certain discrete extracellular substances, such as a glucosaminoglycans (e.g. heparin), fibrin and collagen and with cell surface structure seem to account for many of its biological activities, among which are regulation of adhesion, spreading and locomotion (Mosesson and amrani, 1980). The concentration of Fn in human plasma decreases after extensive destruction such as that occurs in major surgery, burns or other trauma. This decrease has been generally though to be due to increased consumption of soluble plasma Fn in opsonization of particulate and soluble debris from circulation by the reticuloendothelial (RE) system. Fn rapidly appears in injury areas, in experimentally induced blisters, wounded and epithelium tissues (Petersen et al., 1985). Fn accumulates at times of increased vascular permeability and it is produced by cell of blood vessels in response to injury

  17. Performance profiles of major energy producers, 1997

    NONE

    1999-01-01

    The energy industry generally and petroleum and natural gas operations in particular are frequently reacting to a variety of unsettling forces. Falling oil prices, economic upswings, currency devaluations, increasingly rigorous environmental quality standards, deregulation of electricity markets, and continued advances in exploration and production technology were among the challenges and opportunities to the industry in 1997. To analyze the extent to which these and other developments have affected energy industry financial and operating performance, strategies, and industry structure, the Energy Information Administration (EIA) maintains the Financial Reporting Systems (FRS). Through Form EIA-28, major US energy companies annually report to the FRS. Financial and operating information is reported by major lines of business, including oil and gas production (upstream), petroleum refining and marketing (downstream), other energy operations, and nonenergy business. Performance Profiles of Major Producers 1997 examines the interplays of energy markets, companies` strategies, and government policies (in 1997 and in historical context) that gave rise to the results given here. The report also analyzes other key aspects of energy company financial performance as seen through the multifaceted lens provided by the FRS data and complementary data for industry overall. 41 figs., 77 tabs.

  1. Major life events and development of major depression in Parkinson's disease patients

    Rod, Naja Hulvej; Bordelon, Y; Thompson, A

    2012-01-01

    BACKGROUND AND PURPOSE: Non-motor symptoms including depression are important features of Parkinson's disease (PD). We aim to address the relationship between major life events and depression amongst PD patients free of depressive symptoms at baseline. METHODS: New-onset PD patients from California...... were recruited in 2001-2007 and followed up for 3-4 years. The participants (n = 221) were examined by neurologists and responded to comprehensive interviews that included major life events, social support, and coping measures from validated scales. Major depression was assessed using the Structured...... Clinical Interview for the DSM-IV depression module (SCID). RESULTS: More than half of all patients had experienced major life events since diagnosed with PD, and 22 patients developed a major depression. The number of life events was associated with risk of depression in an exposure-dependent manner...

  2. Major gene mutations in fruit tree domestication

    Spiegel-Roy, P.

    1989-01-01

    Though fruit gathering from the wild began long before domestication, fruit tree domestication started only after the establishment of grain agriculture. Banana, fig, date, grape and olive were among the first fruit trees domesticated. Most fruit trees are outbreeders, highly heterozygous and vegetatively propagated. Knowledge of genetics and economic traits controlled by major genes is limited. Ease of vegetative propagation has played a prominent part in domestication; advances in propagation technology will play a role in domestication of new crops. Changes toward domestication affected by major genes include self-fertility in peach, apricot and sour cherry, while the emergence of self-fertile almond populations is more recent and due probably to introgression from Amygdalus webbii. Self-compatibility in the sweet cherry has been attained only by pollen irradiation. A single gene controls sex in Vitis. Wild grapes are dioecious, with most domesticated cultivars hermaphrodite, and only a few females. In the papaya changes from dioecism to hermaphroditism have also occurred. Self-compatible systems have also been selected during domestication in Rubus. Changes towards parthenocarpy and seedlessness during domestication occurred in the banana, citrus, grape, fig and pineapple. In the banana, parthenocarpy is due to three complementary dominant genes; stenospermocarpy in the grape depends on two complementary recessive genes; parthenocarpy and sterility in citrus seems more complicated; however, it can be induced in genetic material of suitable background with ease by irradiation. Presence of persistent syconia in the fig is controlled by a mutant allele P dominant to wild +. Thornlessness in blackberry is recessive, while in the pineapple spineless forms are dominant. Changes affecting fruit composition owing to major genes include the disappearance of amygdalin present in bitter almonds (bitter kernel recessive to sweet), shell hardness in almond, and a recessive

  3. Parvalbumin--the major tropical fish allergen.

    Fish allergy is common in countries where consumption is high. Asian nations are amongst the world's largest consumers of fish but the allergen profiles of tropical fish are unknown. This study sought to evaluate the allergenicity of four commonly consumed tropical fish, the threadfin (Polynemus indicus), Indian anchovy (Stolephorus indicus), pomfret (Pampus chinensis) and tengirri (Scomberomorus guttatus). Immunoglobulin E (IgE) cross-reactivity with parvalbumin of cod fish (Gad c 1), the major fish allergen, was also studied. Detection of tropical fish and cod specific-IgE was performed by UniCap assay, and skin prick tests were also carried out. The IgE-binding components of tropical fish were identified using IgE immunoblot techniques, and cross-reactivity with Gad c 1 was assessed by ELISA inhibition and IgE immunoblot inhibition. Clinically, nine of 10 patients studied were allergic to multiple fish. All patients exhibited detectable specific-IgE to cod fish (10 of 10 skin prick test positive, eight of 10 UniCap assay positive) despite lack of previous exposure. The major allergen of the four tropical fish was the 12-kDa parvalbumin. IgE cross-reactivity of these allergens to Gad c 1 was observed to be moderate to high in the tropical fish studied. Parvalbumins are the major allergens in commonly consumed tropical fish. They are cross-reactive with each other as well as with Gad c 1. Commercial tests for cod fish appear to be sufficient for the detection of tropical fish specific-IgE.

  6. Women's decision to major in STEM fields

    Conklin, Stephanie

    This paper explores the lived experiences of high school female students who choose to enter into STEM fields, and describes the influencing factors which steered these women towards majors in computer science, engineering and biology. Utilizing phenomenological methodology, this study seeks to understand the essence of women's decisions to enter into STEM fields and further describe how the decision-making process varies for women in high female enrollment fields, like biology, as compared with low enrollment fields like, computer science and engineering. Using Bloom's 3-Stage Theory, this study analyzes how relationships, experiences and barriers influenced women towards, and possibly away, from STEM fields. An analysis of women's experiences highlight that support of family, sustained experience in a STEM program during high school as well as the presence of an influential teacher were all salient factors in steering women towards STEM fields. Participants explained that influential teacher worked individually with them, modified and extended assignments and also steered participants towards coursework and experiences. This study also identifies factors, like guidance counselors as well as personal challenges, which inhibited participant's path to STEM fields. Further, through analyzing all six participants' experiences, it is clear that a linear model, like Bloom's 3-Stage Model, with limited ability to include potential barriers inhibited the ability to capture the essence of each participant's decision-making process. Therefore, a revised model with no linear progression which allows for emerging factors, like personal challenges, has been proposed; this model focuses on how interest in STEM fields begins to develop and is honed and then mastered. This study also sought to identify key differences in the paths of female students pursuing different majors. The findings of this study suggest that the path to computer science and engineering is limited. Computer

  7. Enhancing the Accounting Major with Online Learning

    2013-07-01

    Full Text Available Accounting majors who wish to be successful in life must learn to acquire knowledge using all kinds of platforms. The belief that the only way people can learn is by classroom instruction is not supported by research. The authors show how online learning is an important tool for achieving the various goals of accounting education that should include creativity, collaboration, communication, critical thinking and problem solving. The authors conclude that the optimal method to teach accounting is by combining face-to-face learning with on-line learning.

    2016-01-01

    Full Text Available Pectoralis major (PM ruptures are uncommon injuries, although they are becoming more frequent. We report a case of a PM rupture in a young male who presented with axillar pain and absence of the anterior axillary fold after he perceived a snap while lifting 200 kg in the bench press. Diagnosis of PM rupture was suspected clinically and confirmed with imaging studies. The patient was treated surgically, reinserting the tendon to the humerus with suture anchors. One-year follow-up showed excellent results. The patient was recording his training on video, so we can observe in detail the most common mechanism of injury of PM rupture.

  10. Majorization uncertainty relations for mixed quantum states

    Puchała, Zbigniew; Rudnicki, Łukasz; Krawiec, Aleksandra; Życzkowski, Karol

    2018-04-01

    Majorization uncertainty relations are generalized for an arbitrary mixed quantum state ρ of a finite size N. In particular, a lower bound for the sum of two entropies characterizing the probability distributions corresponding to measurements with respect to two arbitrary orthogonal bases is derived in terms of the spectrum of ρ and the entries of a unitary matrix U relating both bases. The results obtained can also be formulated for two measurements performed on a single subsystem of a bipartite system described by a pure state, and consequently expressed as an uncertainty relation for the sum of conditional entropies.

  12. Indirect Climatic Effects of Major Volcanic Eruptions

    Hofmann, D. J.

    2007-05-01

    The direct effects on climate, related to atmospheric emissions to the atmosphere following major volcanic eruptions, are well-known although the sparseness of such eruptions make detailed study on the range of such variations difficult. In general terms, infrared absorption by volcanic emissions to the stratosphere result in local heating early in the event when gaseous sulfur compounds exist. This early period is followed by gas to particle conversion, on a time scale of 1-2 months, promoting the formation of sulfuric acid-water droplets. Coagulation and droplet growth result in the "volcanic stratospheric aerosol layer" which is related to the predominant direct climatic effect of large eruptions, the cooling of the troposphere by backscattering of solar visible radiation to space with a recovery time scale of 1-2 years. In this paper we will discuss some of the less-known "indirect" effects of the volcanic stratospheric aerosol on climate. We label them indirect as they act on climate through intermediary atmospheric constituents. The intermediaries in the volcanic indirect climatic effect are generally atmospheric greenhouse gases or other atmospheric gases and conditions which affect greenhouse gases. For example, cooling of the troposphere following major eruptions reduces the growth rate of atmospheric carbon dioxide related to respiration by the terrestrial biosphere. In addition, redirection of part of the direct solar beam into diffuse radiation by the volcanic stratospheric aerosol stimulates plant photosynthesis, further reducing the carbon dioxide growth rate. The growth rate of the second-most important atmospheric greenhouse gas, methane, is also affected by volcanic emissions. Volcanic stratospheric aerosol particles provide surface area which catalyzes heterogeneous chemical reactions thus stimulating removal of stratospheric ozone, also a greenhouse gas. Although major droughts usually related to ENSO events have opposite effects on carbon

  13. Into the millennium: farewell to majors

    Polczer, S.

    1999-01-01

    Conventional oil discoveries in Alberta peaked in the mid-1960s, marking a shift in the exploration strategies of the oil company majors that established Canada as a player in the world petroleum scene. Increasingly, they are shifting capital out of the country or look to unconventional sources for their new finds. Since they cannot find reserves needed to replace production, major oil companies have began to wind down their exploration programs, or shift to gas or oil sands, or exit altogether. According to the best expert opinion, future traditional exploration and production in Canada will be dominated by technically focused, entrepreneurial niche players using the latest technology to exploit lower quality reservoirs. The same expert source believes that Canada's contribution to the world's petroleum industry after 2000 will be primarily technological development, such as better drilling and well completion techniques. Past evidence suggest that Canada, while not a big player on the world petroleum scene, can and will continue to provide useful contribution to the industry by developing and exporting useful technology

    Full Text Available Abstract Background Epidemiologic estimates are now available for a variety of parameters related to major depression epidemiology (incidence, prevalence, etc.. These estimates are potentially useful for policy and planning purposes, but it is first necessary that they be synthesized into a coherent picture of the epidemiology of the condition. Several attempts to do so have been made using mathematical modeling procedures. However, this information is not easy to communicate to users of epidemiological data (clinicians, administrators, policy makers. Methods In this study, up-to-date data on major depression epidemiology were integrated using a discrete event simulation model. The mathematical model was animated in Virtual Reality Modeling Language (VRML to create a visual, rather than mathematical, depiction of the epidemiology. Results Consistent with existing literature, the model highlights potential advantages of population health strategies that emphasize access to effective long-term treatment. The paper contains a web-link to the animation. Conclusion Visual animation of epidemiological results may be an effective knowledge translation tool. In clinical practice, such animations could potentially assist with patient education and enhanced long-term compliance.

  15. SITO, Environmental Impact of Major Industrial Activities

    Mazzini, M.; Oriolo, F.

    1982-01-01

    1 - Description of problem or function: SITO evaluates the impact of major industrial activities on the environment. The method applied accounts for the alterations of ecological, physico-chemical, aesthetical and social values caused by the development of the considered activity. Such values are usually considered as not quantifiable but very important for the quality of the environment. 2 - Method of solution: The territory affected by the industrial project is described in a one-dimensional (for example a coast development) or two-dimensional representation as a lattice of square meshes of equal size. A major feature of the model is that the impact factors are considered with reference to each single mesh. The following vectors and matrices are evaluated: a) Matrix of environmental quality characteristics. It is the product of the environmental quality index matrix and the vector of weighting factors. b) Vector of the initial environmental values. It is the sum of the columns of matrix (a). c) Matrix obtained when the environmental quality characteristics matrix is multiplied by the vector of project action factors, taking into account distance effects. d) Vector of the final environmental values. This is the sum of columns of matrix (c)

  16. [Cognition - the core of major depressive disorder].

    Polosan, M; Lemogne, C; Jardri, R; Fossati, P

    2016-02-01

    Cognitive deficits have been only recently recognized as a major phenotype determinant of major depressive disorder, although they are an integral part of the definition of the depressive state. Congruent evidence suggest that these cognitive deficits persist beyond the acute phase and may be identified at all ages. The aim of the current study was to review the main meta-analyses on cognition and depression, which encompasses a large range of cognitive domains. Therefore, we discuss the "cold" (attention, memory, executive functions) and "hot" (emotional bias) cognitive impairments in MDD, as well as those of social cognition domains (empathy, theory of mind). Several factors interfere with cognition in MDD such as clinical (melancholic, psychotic...) features, age, age of onset, illness severity, medication and comorbid condition. As still debated in the literature, the type of relationship between the severity of cognitive symptoms and functioning in depression is detailed, thus highlighting their predictive value of functional outcome, independently of the affective symptoms. A better identification of the cognitive deficits in MDD and a monitoring of the effects of different treatments require appropriate instruments, which may be developed by taking advantage of the increasing success of computing tools. Overall, current data suggest a core role for different cognitive deficits in MDD, therefore opening new perspectives for optimizing the treatment of depression. Copyright © 2016 Elsevier Ltd.

  18. Interpersonal psychotherapy (IPT) in major depressive disorder.

    Brakemeier, Eva-Lotta; Frase, Lukas

    2012-11-01

    In this article, we will introduce interpersonal psychotherapy as an effective short-term treatment strategy in major depression. In IPT, a reciprocal relationship between interpersonal problems and depressive symptoms is regarded as important in the onset and as a maintaining factor of depressive disorders. Therefore, interpersonal problems are the main therapeutic targets of this approach. Four interpersonal problem areas are defined, which include interpersonal role disputes, role transitions, complicated bereavement, and interpersonal deficits. Patients are helped to break the interactions between depressive symptoms and their individual interpersonal difficulties. The goals are to achieve a reduction in depressive symptoms and an improvement in interpersonal functioning through improved communication, expression of affect, and proactive engagement with the current interpersonal network. The efficacy of this focused and structured psychotherapy in the treatment of acute unipolar major depressive disorder is summarized. This article outlines the background of interpersonal psychotherapy, the process of therapy, efficacy, and the expansion of the evidence base to different subgroups of depressed patients.

  19. Major Peripheral Nerve Injuries After Elbow Arthroscopy.

    2016-06-01

    To survey the American Society for Surgery of the Hand membership to determine the nature and distribution of nerve injuries treated after elbow arthroscopy. An online survey was sent to all members of the American Society for Surgery of the Hand under an institutional review board-approved protocol. Collected data included the number of nerve injuries observed over a 5-year period, the nature of treatment required for the injuries, and the outcomes observed after any intervention. Responses were anonymous, and results were securely compiled. We obtained 372 responses. A total of 222 nerve injuries were reported. The most injured nerves reported were ulnar, radial, and posterior interosseous (38%, 22%, and 19%, respectively). Nearly half of all patients with injuries required operative intervention, including nerve graft, tendon transfer, nerve repair, or nerve transfer. Of the patients who sustained major injuries, those requiring intervention, 77% had partial or no motor recovery. All minor injuries resolved completely. Our results suggest that major nerve injuries after elbow arthroscopy are not rare occurrences and the risk of these injuries is likely under-reported in the literature. Furthermore, patients should be counseled on this risk because most nerve injuries show only partial or no functional recovery. With the more widespread practice of elbow arthroscopy, understanding the nature and sequelae of significant complications is critically important in ensuring patient safety and improving outcomes.

However, this information is not easy to communicate to users of epidemiological data (clinicians, administrators, policy makers). In this study, up-to-date data on major depression epidemiology were integrated using a discrete event simulation model. The mathematical model was animated in Virtual Reality Modeling Language (VRML) to create a visual, rather than mathematical, depiction of the epidemiology. Consistent with existing literature, the model highlights potential advantages of population health strategies that emphasize access to effective long-term treatment. The paper contains a web-link to the animation. Visual animation of epidemiological results may be an effective knowledge translation tool. In clinical practice, such animations could potentially assist with patient education and enhanced long-term compliance.

    The pattern of structural brain alterations associated with major depressive disorder (MDD) remains unresolved. This is in part due to small sample sizes of neuroimaging studies resulting in limited statistical power, disease heterogeneity and the complex interactions between clinical

  2. Some mechanistic requirements for major transitions.

    Schuster, Peter

    2016-08-19

    Major transitions in nature and human society are accompanied by a substantial change towards higher complexity in the core of the evolving system. New features are established, novel hierarchies emerge, new regulatory mechanisms are required and so on. An obvious way to achieve higher complexity is integration of autonomous elements into new organized systems whereby the previously independent units give up their autonomy at least in part. In this contribution, we reconsider the more than 40 years old hypercycle model and analyse it by the tools of stochastic chemical kinetics. An open system is implemented in the form of a flow reactor. The formation of new dynamically organized units through integration of competitors is identified with transcritical bifurcations. In the stochastic model, the fully organized state is quasi-stationary whereas the unorganized state corresponds to a population with natural selection. The stability of the organized state depends strongly on the number of individual subspecies, n, that have to be integrated: two and three classes of individuals, [Formula: see text] and [Formula: see text], readily form quasi-stationary states. The four-membered deterministic dynamical system, [Formula: see text], is stable but in the stochastic approach self-enhancing fluctuations drive it into extinction. In systems with five and more classes of individuals, [Formula: see text], the state of cooperation is unstable and the solutions of the deterministic ODEs exhibit large amplitude oscillations. In the stochastic system self-enhancing fluctuations lead to extinction as observed with [Formula: see text] Interestingly, cooperative systems in nature are commonly two-membered as shown by numerous examples of binary symbiosis. A few cases of symbiosis of three partners, called three-way symbiosis, have been found and were analysed within the past decade. Four-way symbiosis is rather rare but was reported to occur in fungus-growing ants. The model

    2003-01-01

    Utah oil fields have produced over 1.2 billion barrels (191 million m 3 ). However, the 13.7 million barrels (2.2 million m 3 ) of production in 2002 was the lowest level in over 40 years and continued the steady decline that began in the mid-1980s. The Utah Geological Survey believes this trend can be reversed by providing play portfolios for the major oil producing provinces (Paradox Basin, Uinta Basin, and thrust belt) in Utah and adjacent areas in Colorado and Wyoming. Oil plays are geographic areas with petroleum potential caused by favorable combinations of source rock, migration paths, reservoir rock characteristics, and other factors. The play portfolios will include: descriptions and maps of the major oil plays by reservoir; production and reservoir data; case-study field evaluations; summaries of the state-of-the-art drilling, completion, and secondary/tertiary techniques for each play; locations of major oil pipelines; descriptions of reservoir outcrop analogs; and identification and discussion of land use constraints. All play maps, reports, databases, and so forth, produced for the project will be published in interactive, menu-driven digital (web-based and compact disc) and hard-copy formats. This report covers research activities for the third quarter of the first project year (January 1 through March 31, 2003). This work included gathering field data and analyzing best practices in the eastern Uinta Basin, Utah, and the Colorado portion of the Paradox Basin. Best practices used in oil fields of the eastern Uinta Basin consist of conversion of all geophysical well logs into digital form, running small fracture treatments, fingerprinting oil samples from each producing zone, running spinner surveys biannually, mapping each producing zone, and drilling on 80-acre (32 ha) spacing. These practices ensure that induced fractures do not extend vertically out of the intended zone, determine the percentage each zone contributes to the overall production of

  4. Establishing a legal service for major trauma patients at a major trauma centre in the UK.

    2017-09-01

    Major trauma causes unanticipated critical illness and patients have often made few arrangements for what are sudden and life-changing circumstances. This can lead to financial, housing, insurance, legal and employment issues for patients and their families.A UK law firm worked with the major trauma services to develop a free and comprehensive legal service for major trauma patients and their families at a major trauma centre (MTC) in the UK. In 2013, a legal service was established at North Bristol NHS Trust. Referrals are made by trauma nurse practitioners and it operates within a strict ethical framework. A retrospective analysis of the activity of this legal service between September 2013 and October 2015 was undertaken. 66 major trauma patients were seen by the legal teams at the MTC. 535 hours of free legal advice were provided on non-compensation issues-an average of 8 hours per patient. This initiative confirms a demand for the early availability of legal advice for major trauma patients to address a range of non-compensation issues as well as for identification of potential compensation claims. The availability of advice at the MTC is convenient for relatives who may be spending the majority of their time with injured relatives in hospital. More data are needed to establish the rehabilitation and health effects of receiving non-compensation advice after major injury; however, the utilisation of this service suggests that it should be considered at the UK MTCs. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

  5. The Major Histocompatibility Complex in Transplantation

    Marco Antonio Ayala García

    2012-01-01

    Full Text Available The transplant of organs is one of the greatest therapeutic achievements of the twentieth century. In organ transplantation, the adaptive immunity is considered the main response exerted to the transplanted tissue, since the principal target of the immune response is the MHC (major histocompatibility complex molecules expressed on the surface of donor cells. However, we should not forget that the innate and adaptive immunities are closely interrelated and should be viewed as complementary and cooperating. When a human transplant is performed, HLA (human leukocyte antigens molecules from a donor are recognized by the recipient's immune system triggering an alloimmune response Matching of donor and recipient for MHC antigens has been shown to have a significant positive effect on graft acceptance. This paper will present MHC, the innate and adaptive immunities, and clinical HLA testing.

  6. BROOKHAVEN: Major detectors for RHIC under construction

    Ludlam, Thomas W.

    1994-01-01

    On March 9-10, a cost and schedule review at Brookhaven verified construction readiness for the PHENIX detector (May 1993, page 10). PHENIX thus joins STAR (Solenoidal Tracking at RHIC - November 1991, page 17), whose construction plan was ratified in January 1993, as a major detector to take data when the RHIC heavy ion collider is completed in mid-1999. The goal of both detectors is to search for the transition from ordinary nuclear matter to a new state of matter consisting of (momentarily) unconfined quarks and gluons. This transition to a ''quark-gluon plasma'' (QGP) is predicted to occur under extreme conditions of temperature and energy density, as is likely to be the case in the collision of heavy ions of sufficient energy. RHIC is expected to produce the highest energy densities ever observed on the nuclear scale

  7. MAJOR PROJECTS THAT INFLUENCE WORLD TRADE

    GEORGE CORNEL DUMITRESCU

    2014-11-01

    Full Text Available In 1869, with the opening of the Suez Canal, world trade entered a new era of development. The commercial routes linking the Far East to the western countries were shortened considerably as compared to the maritime corridor around the Cape of Good Hope. In 1914, the opening of the Panama Canal sealed the new deal in world trade, opening for business the shortest commercial routes around the world. After 145 years from the inauguration of the Suez Canal, world trade is on the eve of a new expansion. Two major projects: the expansion of both the Suez and Panama canals, planned to be completed in the next two years, will double their transit capacity. This paper does a comparative analysis of these two strategic projects, underlining the main benefits for Egypt, Panama and world trade, based on the available statistical data, reports and literature in the field.

  8. Environment and safety: major goals for MARS

    Maninger, R.C.

    1983-01-01

    The Mirror Advanced Reactor Study (MARS) is a conceptual design study for a commercial fusion power reactor. One of the major goals of MARS is to develop design guidance so that fusion reactors can meet reasonable expectations for environmental health and safety. One of the first steps in the assessment of health and safety requirements was to examine what the guidelines might be for health and safety in disposal of radioactive wastes from fusion reactors. Then, using these quidelines as criteria, the impact of materials selection upon generation of radioactive wastes through neutron activation of structural materials was investigated. A conclusion of this work is that fusion power systems may need substantial engineering effort in new materials development and selection to meet the probable publicly acceptable levels of radioactivity for waste disposal in the future

  10. Coping with ecological catastrophe: crossing major thresholds

    John Cairns, Jr.

    2004-08-01

    Full Text Available The combination of human population growth and resource depletion makes catastrophes highly probable. No long-term solutions to the problems of humankind will be discovered unless sustainable use of the planet is achieved. The essential first step toward this goal is avoiding or coping with global catastrophes that result from crossing major ecological thresholds. Decreasing the number of global catastrophes will reduce the risks associated with destabilizing ecological systems, which could, in turn, destabilize societal systems. Many catastrophes will be local, regional, or national, but even these upheavals will have global consequences. Catastrophes will be the result of unsustainable practices and the misuse of technology. However, avoiding ecological catastrophes will depend on the development of eco-ethics, which is subject to progressive maturation, comments, and criticism. Some illustrative catastrophes have been selected to display some preliminary issues of eco-ethics.

This work included describing outcrop analogs to the Jurassic Nugget Sandstone and Pennsylvanian Paradox Formation, the major oil producers in the thrust belt and Paradox Basin, respectively. Production-scale outcrop analogs provide an excellent view, often in three dimensions, of reservoir-facies characteristics and boundaries contributing to the overall heterogeneity of reservoir rocks. They can be used as a ''template'' for evaluation of data from conventional core, geophysical and petrophysical logs, and seismic surveys. The Nugget Sandstone was deposited in an extensive dune field that extended from Wyoming to Arizona. Outcrop analogs are

Taken together, these findings suggest that abnormalities in 'hot' cognition may constitute a candidate neurocognitive endophenotype for depression....

  14. Plasma osmotic changes during major abdominal surgery.

    Malone, R A; McLeavey, C A; Arens, J F

    1977-12-01

    Fluid balance across the capillary membrane is maintained normally by a balance of hydrostatic and colloid osmotic pressures (COP). In 12 patients having major intra-abdominal procedures, the COP was followed during the operative and immediate postoperative periods. The patients' intraoperative fluid management consisted of replacing shed blood with blood and following Shires' concept of crystalloid replacement. Significant decreases in COP to approximately two thirds of the initial value occurred in patients having intra-abdominal procedures versus only a 10 percent decrease in those having peripheral procedures (greater than .001). As a result of this decrease in COP, the balance between hydrostatic and colloid osmotic pressures is lost and risk of pulmonary intersitial edema is increased.

  15. Progress on resolution of major surety issues

    Bell, C.R.; Boudreau, J.M.

    1985-01-01

    This paper presents a summary of the major surety issues (safety, environmental protection, sageguards, reliability, quality assurance) that have been identified during Phase I of the SP-100 Program and the progress that has been made in analyzing the most important of these issues in the context of the conceptual design effort. These issues have been identified as inadvertent criticality, toxic material release and dispersion, radiation exposure following end-of-life reentry, potential diversion of special nuclear material, failure to achieve end-of-life neutronic shutdown, and structural predictability for end-of-life re-entry or boost. Because of the complexity of these issues, a simplified conservative approach was taken during Phase I. Progress on these issues has been mainly in the area of increased understanding of the issues, identification of design features to resolve the issues, and quantitative evaluations of the surety characteristics of the various design concepts

    1992-01-01

    Strategic issues facing major oil producers in the 1990s are very diffuse - in contrast with both the 1970s (when strategy meant the response to high oil prices) and the 1980s (when it meant anticipating and exploiting a drop in prices). Mainly upstream issues include the future of price management by OPEC or a successor, the speed of development of new markets for natural gas in power generation and the role of Russia in world energy markets. Other issues include the impact of environmental regulations and taxes on the product mix and on marketing. Human-resource management will continue to face the task of reconciling career opportunities with static or declining manpower requirements; and corporate cash mountains may periodically recur.

  19. Cognitive hypnotherapy for major depressive disorder.

    Alladin, Assen

    2012-04-01

    Since the publication of the special issue on cognitive hypnotherapy in the Journal of Cognitive Psychotherapy: An International Quarterly (1994), there have been major developments in the application of hypnosis to the treatment of depression. However, there is no "one-size-fits-all" treatment for depressive disorders as the conditions represent a complex set of heterogeneous symptoms, involving multiple etiologies. It is thus important for therapists to promote a multimodal approach to treating depressive disorders. This article describes cognitive hypnotherapy (CH), an evidence-based multimodal psychological treatment that can be applied to a wide range of depressed patients. CH combines hypnosis with cognitive behavior therapy as the latter provides the best integrative lodestone for assimilating empirically supported treatment techniques derived from various psychotherapies.

  20. Epigenetic Modifications of Major Depressive Disorder

    Kathleen Saavedra

    2016-08-01

    Full Text Available Major depressive disorder (MDD is a chronic disease whose neurological basis and pathophysiology remain poorly understood. Initially, it was proposed that genetic variations were responsible for the development of this disease. Nevertheless, several studies within the last decade have provided evidence suggesting that environmental factors play an important role in MDD pathophysiology. Alterations in epigenetics mechanism, such as DNA methylation, histone modification and microRNA expression could favor MDD advance in response to stressful experiences and environmental factors. The aim of this review is to describe genetic alterations, and particularly altered epigenetic mechanisms, that could be determinants for MDD progress, and how these alterations may arise as useful screening, diagnosis and treatment monitoring biomarkers of depressive disorders.

  1. Cognitive functioning in major depression - a summary

    Åsa Hammar

    2009-09-01

    Full Text Available The aim of the present paper is to summarize the research during the past decade regarding cognitive functioning in Major Depressive Disorder (MDD. Cognitive impairment in the acute phase of illness has been frequently reported. The findings are shown in different cognitive domains, such as executive functions (EF, attention, memory and psychomotor speed. Fewer reports have investigated cognitive functioning in MDD in longitudinal studies. Some longitudinal reports show that the impairment observed in the acute phase of illness may be long lasting despite symptom reduction and recovery. However, findings regarding cognitive functioning in depression are divergent. Factors that might contribute to the divergent findings, such as depression subtype, severity and comorbidity are discussed. Clinical implications and focus of future research directions is highlighted. .In conclusion, depression is associated with cognitive impairment in the acute phase of illness, and some reports indicate that this impairment might be long lasting despite symptom reduction and recovery.

    BACKGROUND: Identifying patients with recent stroke or transient ischemic attack (TIA) at high risk of major vascular events (MVEs; stroke, myocardial infarction, or vascular death) may help optimize the intensity of secondary preventive interventions. We evaluated the relationships between...... the baseline Framingham Coronary Risk Score (FCRS) and a novel risk prediction model and with the occurrence of MVEs after stroke or TIA in subjects enrolled in the Stroke Prevention by Aggressive Reduction in Cholesterol Level (SPARCL) trial. METHODS: Data from the 4731 subjects enrolled in the SPARCL study...... were analyzed. Hazard ratios (HRs) from Cox regression models were used to determine the risk of subsequent MVEs based on the FCRS predicting 20% or more 10-year coronary heart disease risk. The novel risk model was derived based on multivariable modeling with backward selection. Model discrimination...

    1994-01-01

    The present paper reviews some key factors affecting continued expansion of the use and trade of natural gas, with a particular focus on a group of major gas trade and transport projects now in various stages of consideration. The paper begins by outlining the distribution of potential gas supplies, it also sketches the sectorial and regional structures of potential demand for natural gas. It continues by considering current and emerging trends in the international trade of natural gas by pipeline and as liquefied natural gas (LNG). Within the context thus provided, the paper then details a number of significant potential gas trade and transportation projects individually. Finally, the paper comments on the challenges in financing and implementing gas projects, especially with regard to economic, political, and institutional issues in the producing, transit, and consuming countries

  5. Poverty – a major economical problem

    Assistent Professor Somogyi János

    2008-05-01

    Full Text Available Poverty is the state for the majority of the world’s people and nations. Yet there is plenty offood in the world for everyone. The problem is that hungry people are trapped in severe poverty. They lackthe money to buy enough food to nourish them. Being constantly malnourished, they become weaker and oftensick. This makes them increasingly less able to work, which then makes them even poorer and hungrier.This downward spiral often continues until death for them and their families.Why is this? How is to blame? Poor people for their own predicament? Have they been lazy, madepoor decisions, and been solely responsible for their plight? What about their governments? Have theypursued policies that actually harm successful development? Such causes of poverty and inequality are nodoubt real. But deeper and more global causes of poverty are often less discussed. This article explores variouspoverty problems in more depth.

  6. [Sickness absence associated with major life events].

    Markussen, Simen; Røgeberg, Ole

    2012-05-29

    Sickness absence in the Norwegian workplace doubled in the period 1993-2003. However, the extent to which the driving factors were medical or non-medical remains unclear, as does the extent to which the cause may be found in the composition of the workforce. A differences-in-differences regression model was used to estimate the added sickness absence associated with major life events such as separation, death of spouse and pregnancy in the period 1993-2005. The data were obtained from administrative registers covering the entire Norwegian population, and include all absence periods of 16 days' duration or more reported by a doctor's medical certificate. The primary outcome measures were incidence (the proportion of absentees in a given time window) and absence (the proportion of sick days in a given time window). The level of absence among employees exposed to the specified life events was compared to control groups matched for gender, age, education and income. In 1993, people in each of the three groups exposed to major life events had more frequent and longer periods of absence than people in the control groups. This added sickness absence increased between 1993 and 2005. The changes in added sickness absence were at times significant, particularly for pregnant women. While sickness absence among pregnant women in 1993 was 15.4 percentage points higher than in the control group, the difference had increased to 24.8 percentage points in 2005. We find it improbable for the increase in added sickness absence to be caused by changes in the medical impact of life events or alterations in the workforce composition. We believe the increase is caused by changing attitudes among the working population and in the medical profession towards sickness absence on grounds that are not strictly medical, combined with improved social acceptance and diagnosis of mental health issues, and/or a medicalisation of natural health variations (pregnancy) and emotional distress (grief).

    2007-12-31

    Utah oil fields have produced over 1.33 billion barrels (211 million m{sup 3}) of oil and hold 256 million barrels (40.7 million m{sup 3}) of proved reserves. The 13.7 million barrels (2.2 million m3) of production in 2002 was the lowest level in over 40 years and continued the steady decline that began in the mid-1980s. However, in late 2005 oil production increased, due, in part, to the discovery of Covenant field in the central Utah Navajo Sandstone thrust belt ('Hingeline') play, and to increased development drilling in the central Uinta Basin, reversing the decline that began in the mid-1980s. The Utah Geological Survey believes providing play portfolios for the major oil-producing provinces (Paradox Basin, Uinta Basin, and thrust belt) in Utah and adjacent areas in Colorado and Wyoming can continue this new upward production trend. Oil plays are geographic areas with petroleum potential caused by favorable combinations of source rock, migration paths, reservoir rock characteristics, and other factors. The play portfolios include descriptions and maps of the major oil plays by reservoir; production and reservoir data; case-study field evaluations; locations of major oil pipelines; identification and discussion of land-use constraints; descriptions of reservoir outcrop analogs; and summaries of the state-of-the-art drilling, completion, and secondary/tertiary recovery techniques for each play. The most prolific oil reservoir in the Utah/Wyoming thrust belt province is the eolian, Jurassic Nugget Sandstone, having produced over 288 million barrels (46 million m{sup 3}) of oil and 5.1 trillion cubic feet (145 billion m{sup 3}) of gas. Traps form on discrete subsidiary closures along major ramp anticlines where the depositionally heterogeneous Nugget is also extensively fractured. Hydrocarbons in Nugget reservoirs were generated from subthrust Cretaceous source rocks. The seals for the producing horizons are overlying argillaceous and gypsiferous beds in

    Full Text Available Abstract Background Leishmania represent a complex of important human pathogens that belong to the systematic order of the kinetoplastida. They are transmitted between their human and mammalian hosts by different bloodsucking sandfly vectors. In their hosts, the Leishmania undergo several differentiation steps, and their coordination and optimization crucially depend on numerous interactions between the parasites and the physiological environment presented by the fly and human hosts. Little is still known about the signalling networks involved in these functions. In an attempt to better understand the role of cyclic nucleotide signalling in Leishmania differentiation and host-parasite interaction, we here present an initial study on the cyclic nucleotide-specific phosphodiesterases of Leishmania major. Results This paper presents the identification of three class I cyclic-nucleotide-specific phosphodiesterases (PDEs from L. major, PDEs whose catalytic domains exhibit considerable sequence conservation with, among other, all eleven human PDE families. In contrast to other protozoa such as Dictyostelium, or fungi such as Saccharomyces cerevisiae, Candida ssp or Neurospora, no genes for class II PDEs were found in the Leishmania genomes. LmjPDEA contains a class I catalytic domain at the C-terminus of the polypeptide, with no other discernible functional domains elsewhere. LmjPDEB1 and LmjPDEB2 are coded for by closely related, tandemly linked genes on chromosome 15. Both PDEs contain two GAF domains in their N-terminal region, and their almost identical catalytic domains are located at the C-terminus of the polypeptide. LmjPDEA, LmjPDEB1 and LmjPDEB2 were further characterized by functional complementation in a PDE-deficient S. cerevisiae strain. All three enzymes conferred complementation, demonstrating that all three can hydrolyze cAMP. Recombinant LmjPDEB1 and LmjPDEB2 were shown to be cAMP-specific, with Km values in the low micromolar range

    Organisation and management are factors of paramount importance in higher education for achieving higher quality of training, better professional adaptation, and more effective career pursuance of the students. The present study analyses the use of various teaching methods for the students in the major of Healthcare Management as they are employed in two medical universities. We conducted a detailed questionnaire survey which included the students in the Healthcare Management major in the Faculty of Public Health (FPH) at Sofia Medical University (SMU) and the Medical Faculty of Plovdiv Medical University (PMU). The students were surveyed for two consecutive academic years (2004/2005 and 2005/2006). The logical units of study were 198 students completing their baccalaureate programs in Healthcare Management: 145 (73.23+/-3.15%) in the FPH, SMU and 53 (26.77+/-3.15%) in the PMU (the greater number of students from the SMU was due to the greater number of students admitted into the Sofia Medical University). The technical units of study were the Faculty of Public Health in the Medical University in Sofia and the Medical faculty in the Medical University in Plovdiv. The survey was carried out using our own questionnaire form comprising 51 questions (open and closed), some of them allowing more than one answer. The collected sociological data were analysed using SPSS v. 13.0, and the diagrams were made using Microsoft Excel' 97. We used the alternative, non-parametric and graphic analyses to illustrate the processes and events at a level of significance P PMU and 26.32+/-1.91% for SMU). This format of teaching is also considered to be the easiest with regard to learning the study material by 22.75+/-3.25% of the PMU graduates and 27.56+/-2.38% of the SMU graduates. The PMU students regard seminars, individual work and discussions as the format that afford the easiest way to acquire knowledge (22.16+/-3.21%, 21.56+/-3.18%, (18.56+/-3.01%, respectively).

    2016-07-01

    Full Text Available This paper differs from scientific papers describing current research. In line with the theme of this special issue, it challenges conventional risk management practice against the background of former research results successfully finished decades ago. It is well-known that conventional practice frequently results in budget overruns of large projects. International reviews document that. Severe delays of schedules are also well-known. This paper describes successful research results from almost three decades ago, which successfully challenges this severe problem and has led to new practices. The research involved is an unusual mix: Scandinavian researchers from psychology, statistical theory and engineering economy. The resulting procedure has been widely used since around 1990 and challenges conventional procedures. The procedure is documented to be able to yield statistically correct prognoses, when the “rules of the game” have been correctly followed. After a short summary of the basic situation, this paper summarizes the research, followed by some resulting experiences, focusing on two recent studies each of 40 infrastructures and other major projects. In both sets, the actual final cost largely equaled the expected project cost. This result is a marked change from international past and present experience. Finally, the need for further research and progress is discussed.

  14. Osteoporosis Syndrome in Thalassaemia Major: An Overview

    Meropi Toumba

    2010-01-01

    Full Text Available Osteoporosis in thalassaemia major (TM represents a prominent cause of morbidity. The mechanism of pathogenesis of bone disease (BD in TM is multifactorial and complicated. Peak bone mass is achieved shortly after completion of puberty and normally remains stable until the third decade of life when age-related bone mass begins. Growth hormone (GH and sex steroids play a crucial role in bone remodeling and in the maintenance of skeletal architecture during adult life. GH and insulin growth factors (IGFs have anabolic effect in bone formation. Sex steroids act probably by increasing the expression of RANKL by osteoblastic cells and alterations in the RANK/RANKL/OPG system in favor of osteoclasts. Impaired GH secretion and lack of sex steroids in thalassemic patients due to pituitary damage, contribute to failure of achieving optimal peak bone mass. Other endocrine complications such as hypoparathyroidism and vitamin D deficiency have also a detrimental role on bones in TM. It is still questionable whether the international criteria for defining osteopenia and osteoporosis are relevant to patients with TM; also a question arises for the diagnostic methods such as DEXA scan and management of osteoporosis with known treatment protocols, in the thalassaemic patient.

  15. Thermal Radiation Anomalies Associated with Major Earthquakes

    2017-01-01

    Recent developments of remote sensing methods for Earth satellite data analysis contribute to our understanding of earthquake related thermal anomalies. It was realized that the thermal heat fluxes over areas of earthquake preparation is a result of air ionization by radon (and other gases) and consequent water vapor condensation on newly formed ions. Latent heat (LH) is released as a result of this process and leads to the formation of local thermal radiation anomalies (TRA) known as OLR (outgoing Longwave radiation, Ouzounov et al, 2007). We compare the LH energy, obtained by integrating surface latent heat flux (SLHF) over the area and time with released energies associated with these events. Extended studies of the TRA using the data from the most recent major earthquakes allowed establishing the main morphological features. It was also established that the TRA are the part of more complex chain of the short-term pre-earthquake generation, which is explained within the framework of a lithosphere-atmosphere coupling processes.

  16. Environmental influences on major waterfowl diseases

    Friend, M.

    1992-01-01

    The decline of North American waterfowl resources since the 1960s is well-known to this audience and need not be detailed to establish that population numbers for several key waterfowl species are at or near their lowest levels since records have been kept. Loss of habitat is an accepted major cause for the decline of waterfowl numbers and the wildlife conservation community is responding with initiatives to prevent further loss of existing wetland acreage, restoration for degraded wetlands and creation of new wetlands. Numerous joint ventures focusing on key waterfowl habitat requirements are being developed under the North American Waterfowl Plan. The importance of habitat loss also is reflected in many of the presentations at this conference on wetland conservation, including one special session devoted solely to that topic. A basic premise of the focus on wetlands is that restoration of waterfowl populations is habitat dependent. This is a tenable thesis if other factors suppressing waterfowl numbers are dealt with and the habitat base being enhanced sustains waterfowl rather than contributes to their death. My presentation addresses disease as a factor suppressing waterfowl numbers and the relation of habitat quantity and quality with waterfowl disease.

  17. Resource Demand Scenarios for the Major Metals.

    2018-03-06

    The growth in metal use in the past few decades raises concern that supplies may be insufficient to meet demands in the future. From the perspective of historical and current use data for seven major metals-iron, manganese, aluminum, copper, nickel, zinc, and lead-we have generated several scenarios of potential metal demand from 2010 to 2050 under alternative patterns of global development. We have also compared those demands with various assessments of potential supply to midcentury. Five conclusions emerge: (1) The calculated demand for each of the seven metals doubles or triples relative to 2010 levels by midcentury; (2) The largest demand increases relate to a scenario in which increasingly equitable values and institutions prevail throughout the world; (3) The metal recycling flows in the scenarios meet only a modest fraction of future metals demand for the next few decades; (4) In the case of copper, zinc, and perhaps lead, supply may be unlikely to meet demand by about midcentury under the current use patterns of the respective metals; (5) Increased rates of demand for metals imply substantial new energy provisioning, leading to increases in overall global energy demand of 21-37%. These results imply that extensive technological transformations and governmental initiatives could be needed over the next several decades in order that regional and global development and associated metal demand are not to be constrained by limited metal supply.

  18. Contraction of online response to major events.

    Szell, Michael; Grauwin, Sébastian; Ratti, Carlo

    2014-01-01

    Quantifying regularities in behavioral dynamics is of crucial interest for understanding collective social events such as panics or political revolutions. With the widespread use of digital communication media it has become possible to study massive data streams of user-created content in which individuals express their sentiments, often towards a specific topic. Here we investigate messages from various online media created in response to major, collectively followed events such as sport tournaments, presidential elections, or a large snow storm. We relate content length and message rate, and find a systematic correlation during events which can be described by a power law relation--the higher the excitation, the shorter the messages. We show that on the one hand this effect can be observed in the behavior of most regular users, and on the other hand is accentuated by the engagement of additional user demographics who only post during phases of high collective activity. Further, we identify the distributions of content lengths as lognormals in line with statistical linguistics, and suggest a phenomenological law for the systematic dependence of the message rate to the lognormal mean parameter. Our measurements have practical implications for the design of micro-blogging and messaging services. In the case of the existing service Twitter, we show that the imposed limit of 140 characters per message currently leads to a substantial fraction of possibly dissatisfying to compose tweets that need to be truncated by their users.

  19. The Chernobyl Forum: major findings and recommendations

    Balonov, M.I.

    2007-01-01

    The accident at the Chernobyl NPP in 1986 was the most severe in the history of the nuclear industry, causing a huge release of radionuclides over large areas of Europe. The recently completed Chernobyl Forum concluded that after a number of years, along with reduction of radiation levels and accumulation of humanitarian consequences, severe social and economic depression of the affected regions and associated psychological problems of the general public and the workers had become the most significant problem to be addressed by the authorities. The majority of the affected land is now safe for life and economic activities. However, in the Chernobyl Exclusion Zone and in some limited areas of Belarus, Russia and Ukraine some restrictions on land-use should be retained for decades to come. Most of the 600,000 emergency and recovery operation workers and five million residents of the contaminated areas in Belarus, Russia and Ukraine received relatively minor radiation doses which are comparable with the natural background levels. Apart from the dramatic increase in thyroid cancer incidence among those exposed at a young age and some increase of leukaemia and solid cancer in most exposed workers, there is no clearly demonstrated increase in the somatic diseases due to radiation

  20. Major savings promised by new dipper technology

    Ednie, H.

    2005-10-01

    A Canadian rope shovel dipper prototype was tested at the Suncor oil sands operations in May 2005. The 3 cubic yard JPi 2005 series dipper was designed by JPi, a geo-industry engineering consultant firm. The new design minimizes shovel dipper wear and resistance while digging at a rock face. This simple concept could offer major savings for mine operators. The main feature of the shovel dipper is its shape. Rather than having a straight-lined profile, the lip to latch keeper is curved to match the range of motions of the machine itself. This provides optimum penetration angles with minimum resistance when digging, thereby increasing productivity while eliminating heel wear. The dipper was originally designed to dig softer materials, but can actually be used to dig or scoop any material from blasted hard rock to the softest oil sand. The dipper is also more open at the door than at the lip allowing the oil sand to naturally flow out of the dipper upon release. The prototype was demonstrated to an industry-wide audience in May 2005 on a recently rebuilt 1949 Dominion 500 shovel. Preliminary results indicate that the design is meeting the expectations of the designer. However, more tests are scheduled and JPi will continue to seek collaborations and partnerships with mining operations to produce and test a 75 cubic yard version of the dipper for use with modern shovels. 2 figs.

  1. Potentialities of robots in major accident situations

    Chevallier, M.

    2013-01-01

    The INTRA group was founded in 1988, 2 years after the Chernobyl accident with the purpose of a cooperation between EDF, Cogema and CEA in order to develop and operate a fleet of robots able to intervene and replace man in a nuclear facility in case of major accident. Now INTRA disposes of 5 types of equipment: first, robots for the inside of buildings (they can overcome 40 cm high obstacles, open doors, go upstairs) they are wire-guided and enjoy a battery life of 6 to 8 hours. Secondly, robots for the open air that are able to move in very degraded grounds, they are remote controlled through radio-waves and their autonomy range nears 5 km. Thirdly, public works vehicles, INTRA has developed an excavator and a dump truck, both are remote controlled, they allow the making of any earth work. Fourthly, INTRA has developed 2 systems of contamination measurement: Skylink and Helinuc. Skylink is a system of 20 radiation monitors that can be dispatched on the contaminated zone, their data is collected through radio waves. Helinuc is a kind of gamma spectrometer that is helicopter-borne and can draw a map of the contamination around the installation. Fifthly, 2 drones are being tested, they will be fitted with radiation monitors. (A.C.)

  2. Perceptive biases in major depressive episode.

    Marine Naudin

    Full Text Available INTRODUCTION: Alterations in emotional processing occur during a major depressive episode (MDE, and olfaction and facial expressions have implications in emotional and social interactions. To gain a better understanding of these processes, we characterized the perceptive sensorial biases, potential links, and potential remission after antidepressant treatment of MDE. METHODS: We recruited 22 patients with acute MDE, both before and after three months of antidepressant treatment, and 41 healthy volunteers matched by age and smoking status. The participants underwent a clinical assessment (Mini International Neuropsychiatry Interview, Montgomery-Åsberg Depression Rating Scale, State-Trait Anxiety Inventory, Physical and Social Anhedonia scales, Pleasure-Displeasure Scale, an olfactory evaluation (hedonic aspect, familiarity and emotional impact of odors, and a computerized Facial Affect Recognition task. RESULTS: MDE was associated with an olfactory bias concerning hedonic and emotional aspects, including negative olfactory alliesthesia (unpleasant odorants perceived as more unpleasant, facial emotion expression recognition (happy facial expressions, and in part olfactory anhedonia (pleasant odorants perceived as less pleasant. In addition, the results revealed that these impairments represent state markers of MDE, suggesting that the patients recovered the same sensory processing as healthy subjects after antidepressant treatment. DISCUSSION: This study demonstrated that MDE is associated with negative biases toward olfactory perception and the recognition of facial emotional expressions. The link between these two sensory parameters suggests common underlying processes.

    Domestic and open biomass burning are poorly-understood, major influences on Earth's atmosphere composed of countless individual fires that (along with their products) are difficult to quantify spatially and temporally. Each fire is a minimally-controlled complex phenomenon producing a diverse suite of gases and aerosols that experience many different atmospheric processing scenarios. New lab, airborne, and space-based observations along with model and algorithm development are significantly improving our knowledge of biomass burning. Several campaigns provided new detailed emissions profiles for previously undersampled fire types; including wildfires, cooking fires, peat fires, and agricultural burning; which may increase in importance with climate change and rising population. Multiple campaigns have better characterized black and brown carbon and used new instruments such as high resolution PTR-TOF-MS and 2D-GC/TOF-MS to improve quantification of semi-volatile precursors to aerosol and ozone. The aerosol evolution and formation of PAN and ozone, within hours after emission, have now been measured extensively. The NASA DC-8 sampled smoke before and after cloud-processing in two campaigns. The DC-8 performed continuous intensive sampling of a wildfire plume from the source in California to Canada probing multi-day aerosol and trace gas aging. Night-time plume chemistry has now been measured in detail. Fire inventories are being compared and improved, as is modeling of mass transfer between phases and sub-grid photochemistry for global models.

  4. Trochleoplasty in major trochlear dysplasia: current concepts

    2012-02-01

    Full Text Available Abstract Trochleoplasty is the theoretical solution to persistent symptoms (pain and/or instability related to trochlear dysplasia where there is not only a trochlear flatness but also a trochlear prominence. The threshold of prominence indicating surgical intervention has as yet not been determined. A bump of 5 mm is generally accepted as the inferior limit. Given the interventional nature of this demanding procedure, it should be proposed in selected cases after considerable discussion with the patient. Trochleoplasty is indicated as a primary procedure for major trochlear dysplasia with a prominence > 5 mm. Stabilization is obtained in most of the cases with the risk of residual mild anterior knee pain. It is also indicated as a salvage procedure when a previous surgery failed. Despite the reputation of the procedure, the published results are encouraging in terms of prevention of re-dislocation, satisfaction index, and radiological outcomes. Post-operative stiffness is the main complication, which may require manipulation under anaesthesia or arthroscopic arthrolysis. There are few other complications reported and to date secondary necrosis of the trochlea has not been reported. Technically speaking, the deepening trochleoplasty is a difficult procedure without reliable landmarks. We propose a recession wedge trochleoplasty which is an easier procedure. It is never undertaken as an isolated procedure, but always in conjunction with other realignment procedures of the extensor apparatus according to the "a la carte" surgery concept.

  5. Affective Priming in Major Depressive Disorder

    2012-10-01

    Full Text Available Research on cognitive biases in depression has provided considerable evidence for the impact of emotion on cognition. Individuals with depression tend to preferentially process mood-congruent material and to show deficits in the processing of positive material leading to biases in attention, memory, and judgments. More research is needed, however, to fully understand which cognitive processes are affected. The current study further examines the impact of emotion on cognition using a priming design with facial expressions of emotion. Specifically, this study tested whether the presentation of facial expressions of emotion affects subsequent processing of affective material in participants with major depressive disorder (MDD and healthy controls (CTL. Facial expressions displaying happy, sad, angry, disgusted, or neutral expressions were presented as primes for 500ms, and participants’ speed to identify a subsequent target’s emotional expression was assessed. All participants displayed greater interference from emotional versus neutral primes, marked by slower response times to judge the emotion of the target face when it was preceded by an emotional prime. Importantly, the CTL group showed the strongest interference when happy emotional expressions served as primes whereas the MDD group failed to show this bias. These results add to a growing literature that shows that depression is associated with difficulties in the processing of positive material.

  6. Mice lacking major brain gangliosides develop parkinsonism.

    Wu, Gusheng; Lu, Zi-Hua; Kulkarni, Neil; Amin, Ruchi; Ledeen, Robert W

    2011-09-01

    Parkinson's disease (PD) is the second most prevalent late-onset neurodegenerative disorder that affects nearly 1% of the global population aged 65 and older. Whereas palliative treatments are in use, the goal of blocking progression of motor and cognitive disability remains unfulfilled. A better understanding of the basic pathophysiological mechanisms underlying PD would help to advance that goal. The present study provides evidence that brain ganglioside abnormality, in particular GM1, may be involved. This is based on use of the genetically altered mice with disrupted gene Galgt1 for GM2/GD2 synthase which depletes GM2/GD2 and all the gangliotetraose gangliosides that constitute the major molecular species of brain. These knockout mice show overt motor disability on aging and clear indications of motor impairment with appropriate testing at an earlier age. This disability was rectified by L-dopa administration. These mice show other characteristic symptoms of PD, including depletion of striatal dopamine (DA), loss of DA neurons of the substantia nigra pars compacta, and aggregation of alpha synuclein. These manifestations of parkinsonism were largely attenuated by administration of LIGA-20, a membrane permeable analog of GM1 that penetrates the blood brain barrier and enters living neurons. These results suggest that perturbation of intracellular mechanisms mediated by intracellular GM1 may be a contributing factor to PD.

  8. Burkholderia glumae: next major pathogen of rice?

    Ham, Jong Hyun; Melanson, Rebecca A; Rush, Milton C

    2011-05-01

    Burkholderia glumae causes bacterial panicle blight of rice, which is an increasingly important disease problem in global rice production. Toxoflavin and lipase are known to be major virulence factors of this pathogen, and their production is dependent on the TofI/TofR quorum-sensing system, which is mediated by N-octanoyl homoserine lactone. Flagellar biogenesis and a type III secretion system are also required for full virulence of B. glumae. Bacterial panicle blight is thought to be caused by seed-borne B. glumae; however, its disease cycle is not fully understood. In spite of its economic importance, neither effective control measures for bacterial panicle blight nor rice varieties showing complete resistance to the disease are currently available. A better understanding of the molecular mechanisms underlying B. glumae virulence and of the rice defence mechanisms against the pathogen would lead to the development of better methods of disease control for bacterial panicle blight.

  9. Major new sources of biological ice nuclei

    Moffett, B. F.; Hill, T.; Henderson-Begg, S. K.

    2009-12-01

    Almost all research on biological ice nucleation has focussed on a limited number of bacteria. Here we characterise several major new sources of biogenic ice nuclei. These include mosses, hornworts, liverworts and cyanobacteria. Ice nucleation in the eukaryotic bryophytes appears to be ubiquitous. The temperature at which these organisms nucleate is that at which the difference in vapour pressure over ice and water is at or close to its maximum. At these temperatures (-8 to -18 degrees C) ice will grow at the expense of supercooled water. These organisms are dependent for their water on occult precipitation - fog, dew and cloudwater which by its nature is not collected in conventional rain gauges. Therefore we suggest that these organism produce ice nuclei as a water harvesting mechanism. Since the same mechanism would also drive the Bergeron-Findeisen process, and as moss is known to become airborne, these nuclei may have a role in the initiation of precipitation. The properties of these ice nuclei are very different from the well characterised bacterial nuclei. We will also present DNA sequence data showing that, although related, the proteins responsible are only very distantly related to the classical bacterial ice nuclei.

    Clinical utility of Electroencephalography (EEG) based diagnostic studies is less clear for major depressive disorder (MDD). In this paper, a novel machine learning (ML) scheme was presented to discriminate the MDD patients and healthy controls. The proposed method inherently involved feature extraction, selection, classification and validation. The EEG data acquisition involved eyes closed (EC) and eyes open (EO) conditions. At feature extraction stage, the de-trended fluctuation analysis (DFA) was performed, based on the EEG data, to achieve scaling exponents. The DFA was performed to analyzes the presence or absence of long-range temporal correlations (LRTC) in the recorded EEG data. The scaling exponents were used as input features to our proposed system. At feature selection stage, 3 different techniques were used for comparison purposes. Logistic regression (LR) classifier was employed. The method was validated by a 10-fold cross-validation. As results, we have observed that the effect of 3 different reference montages on the computed features. The proposed method employed 3 different types of feature selection techniques for comparison purposes as well. The results show that the DFA analysis performed better in LE data compared with the IR and AR data. In addition, during Wilcoxon ranking, the AR performed better than LE and IR. Based on the results, it was concluded that the DFA provided useful information to discriminate the MDD patients and with further validation can be employed in clinics for diagnosis of MDD.

    Trauma is a leading cause of death and disability worldwide. Patients presenting with severe trauma and burns benefit from specifically trained multidisciplinary teams. Regional trauma systems have shown improved outcomes for trauma patients. The aim of this study is to determine whether the development of major trauma systems have improved the management of patients with major burns. A retrospective study was performed over a four-year period reviewing all major burns in adults and children received at a regional burns centre in the UK before and after the implementation of the regional trauma systems and major trauma centres (MTC). Comparisons were drawn between three areas: (1) Patients presenting before the introduction of MTC and after the introduction of MTC. (2) Patients referred from MTC and non-MTC within the region, following the introduction of MTC. (3) Patients referred using the urban trauma protocol and the rural trauma protocol. Following the introduction of regional trauma systems and major trauma centres (MTC), isolated burn patients seen at our regional burns centre did not show any significant improvement in transfer times, admission resuscitation parameters, organ dysfunction or survival when referred from a MTC compared to a non-MTC emergency department. There was also no significant difference in survival when comparing referrals from all hospitals pre and post establishment of the major trauma network. No significant outcome benefit was demonstrated for burns patients referred via MTCs compared to non-MTCs. We suggest further research is needed to ascertain whether burns patients benefit from prolonged transfer times to a MTC compared to those seen at their local hospitals prior to transfer to a regional burns unit for further specialist care.

  12. A major genetic component of BSE susceptibility

    Juling, Katrin; Schwarzenbacher, Hermann; Williams, John L; Fries, Ruedi

    2006-01-01

    Background Coding variants of the prion protein gene (PRNP) have been shown to be major determinants for the susceptibility to transmitted prion diseases in humans, mice and sheep. However, to date, the effects of polymorphisms in the coding and regulatory regions of bovine PRNP on bovine spongiform encephalopathy (BSE) susceptibility have been considered marginal or non-existent. Here we analysed two insertion/deletion (indel) polymorphisms in the regulatory region of bovine PRNP in BSE affected animals and controls of four independent cattle populations from UK and Germany. Results In the present report, we show that two previously reported 23- and 12-bp insertion/deletion (indel) polymorphisms in the regulatory region of bovine PRNP are strongly associated with BSE incidence in cattle. Genotyping of BSE-affected and control animals of UK Holstein, German Holstein, German Brown and German Fleckvieh breeds revealed a significant overrepresentation of the deletion alleles at both polymorphic sites in diseased animals (P = 2.01 × 10-3 and P = 8.66 × 10-5, respectively). The main effect on susceptibility is associated with the 12-bp indel polymorphism. Compared with non-carriers, heterozygous and homozygous carriers of the 12-bp deletion allele possess relatively higher risks of having BSE, ranging from 1.32 to 4.01 and 1.74 to 3.65 in the different breeds. These values correspond to population attributable risks ranging from 35% to 53%. Conclusion Our results demonstrate a substantial genetic PRNP associated component for BSE susceptibility in cattle. Although the BSE risk conferred by the deletion allele of the 12-bp indel in the regulatory region of PRNP is substantial, the main risk factor for BSE in cattle is environmental, i.e. exposure to feedstuffs contaminated with the infectious agent.

    Full Text Available Abstract Background Coding variants of the prion protein gene (PRNP have been shown to be major determinants for the susceptibility to transmitted prion diseases in humans, mice and sheep.

  14. Dichotomy of major genes and polygenes

    Jain, S.

    1989-01-01

    In order to facilitate domestication and breeding of new or underexploited crop species, the genetic basis of many traits must be critically investigated, and both naturally occurring and induced mutations should be utilized. Classically, most breeding procedures have invoked the dichotomy of major genes versus polygenes (or discrete versus continuously varying traits) which is briefly reviewed here from several viewpoints. Clearly, the evidence for two distinct classes of genes (or gene effects on phenotype) and traits is largely a product of different forms of genetic analyses and their primary objectives as well as of researchers' expectations. Superimposed on the simplest Mendelian ratios and genome maps are numerous sources of molecular variation and gene expression at many levels of phenotypic description. Many attempts to delineate developmental pathways and to identify genes controlling discrete vs. quantitative phenotypic variation have resulted in emphasis on multigenic models with specific gene effects at mappable loci but nonetheless modified by small effects. Thus, quantitative genetic variation may arise from multi-genic and multi-allelic systems of both structural and regulatory gene action and gene interactions which, from an empirical breeding perspective, might be adequately described by the biometrical and evolutionary models. Polygenic analyses were conceptually based on genetic parameters in these models (as caricatures of reality) but efforts to modify or reject them by identifying and mapping sources of phenotypic variation through newer genetic methods are likely to enrich and not displace biometrical methods. Domestication programmes, in particular, should employ the entire array of genetic discoveries and methodologies. (author). 71 refs, 1 fig., 1 tab

  15. Major depression and secondhand smoke exposure.

    2018-01-01

    Epidemiological studies have consistently linked smoking to poor mental health. Among non-smokers, some studies have also reported associations between secondhand smoke exposure and psychological symptoms. However, an association between secondhand smoke exposure and depressive disorders has not been well established. This analysis used cross-sectional data from a series of 10 population surveys conducted in Canada between 2003 and 2013. The surveys targeted the Canadian household population, included a brief structured interview for past year major depressive episode (MDE) and included items assessing secondhand smoke exposure. We used two-stage individual-level random-effects meta-regression to synthesize results from these surveys. Over the study interval, about 20% of non-smokers reported substantial exposure to secondhand smoke. In this group, the pooled annual prevalence of MDE was 6.1% (95% CI 5.3-6.9) compared to 4.0% (95% CI 3.7-4.3) in non-smokers without secondhand smoke exposure. The crude odds ratio was 1.5 (95% CI 1.4-1.7). With adjustment for a set of potential confounding variables the odds ratio was unchanged, 1.4 (95% CI 1.2 - 1.6). These results provide additional support for public health measures aimed at reducing secondhand smoke exposure. A causal connection between secondhand smoke exposure and MDEs cannot be confirmed due to the cross-sectional nature of the data. Longitudinal studies are needed to establish temporal sequencing.

  16. Major advances in fundamental dairy cattle nutrition.

    Drackley, J K; Donkin, S S; Reynolds, C K

    2006-04-01

    Fundamental nutrition seeks to describe the complex biochemical reactions involved in assimilation and processing of nutrients by various tissues and organs, and to quantify nutrient movement (flux) through those processes. Over the last 25 yr, considerable progress has been made in increasing our understanding of metabolism in dairy cattle. Major advances have been made at all levels of biological organization, including the whole animal, organ systems, tissues, cells, and molecules. At the whole-animal level, progress has been made in delineating metabolism during late pregnancy and the transition to lactation, as well as in whole-body use of energy-yielding substrates and amino acids for growth in young calves. An explosion of research using multicatheterization techniques has led to better quantitative descriptions of nutrient use by tissues of the portal-drained viscera (digestive tract, pancreas, and associated adipose tissues) and liver. Isolated tissue preparations have provided important information on the interrelationships among glucose, fatty acid, and amino acid metabolism in liver, adipose tissue, and mammary gland, as well as the regulation of these pathways during different physiological states. Finally, the last 25 yr has witnessed the birth of "molecular biology" approaches to understanding fundamental nutrition. Although measurements of mRNA abundance for proteins of interest already have provided new insights into regulation of metabolism, the next 25 yr will likely see remarkable advances as these techniques continue to be applied to problems of dairy cattle biology. Integration of the "omics" technologies (functional genomics, proteomics, and metabolomics) with measurements of tissue metabolism obtained by other methods is a particularly exciting prospect for the future. The result should be improved animal health and well being, more efficient dairy production, and better models to predict nutritional requirements and provide rations to meet

  17. Photoinactivation of major bacterial pathogens in aquaculture

    2016-08-01

    Full Text Available Abstract Background Significant increases in the bacterial resistance to various antibiotics have been found in fish farms. Non-antibiotic therapies for infectious diseases in aquaculture are needed. In recent years, light-emitting diode technology has been applied to the inactivation of pathogens, especially those affecting humans. The purpose of this study was to assess the effect of blue light (wavelengths 405 and 465 nm on seven major bacterial pathogens that affect fish and shellfish important in aquaculture. Results We successfully demonstrate inactivation activity of a 405/465-nm LED on selected bacterial pathogens. Although some bacteria were not fully inactivated by the 465-nm light, the 405-nm light had a bactericidal effect against all seven pathogens, indicating that blue light can be effective without the addition of a photosensitizer. Photobacterium damselae, Vibrio anguillarum, and Edwardsiella tarda were the most susceptible to the 405-nm light (36.1, 41.2, and 68.4 J cm−2, respectively, produced one log reduction in the bacterial populations, whereas Streptococcus parauberis was the least susceptible (153.8 J cm−2 per one log reduction. In general, optical density (OD values indicated that higher bacterial densities were associated with lower inactivating efficacy, with the exception of P. damselae and Vibrio harveyi. In conclusion, growth of the bacterial fish and shellfish pathogens evaluated in this study was inactivated by exposure to either the 405- or 465-nm light. In addition, inactivation was dependent on exposure time. Conclusions This study presents that blue LED has potentially alternative therapy for treating fish and shellfish bacterial pathogens. It has great advantages in aspect of eco-friendly treating methods differed from antimicrobial methods.

  18. Generalized Anxiety and Major Depressive syndrome ...

    Objective: Environmental exposure to manganese (Mn) may cause generalized anxiety (GA) and major depression (MD) in residents living in Mn-exposed areas. Marietta and East Liverpool are two Ohio towns identified as having elevated levels of Mn. The objective was to determine if levels of Mn exposure were associated with levels of GA and MD.Participants and methods: 186 participants (Mean age: 55.0 ± 10.80) were examined. Levels of air-Mn were assessed over a period of ten years using U.S. EPA’s AERMOD dispersion model. Average air-Mn exposure was 0.53 μg/m3 in the two towns. The GA syndrome was comprised of anxiety, obsessive-compulsive, and phobic scales from the Symptom Checklist (SCL-90-R). The MD syndrome was comprised of depression, anxiety, and psychoticism scales also from the SCL-90-R. Linear regression models were used to determine the relationship between Mn and GA, MD and the specific components of each.Results: Elevated air-Mn was associated with GA (β= 0.240, p=0.002), and MD (β= 0.202, p=0.011). Air-Mn was associated with specific components of GA anxiety (β= 0.255, p=0.001), phobic anxiety (β= 0.159, p=0.046), and obsessive-compulsive (β= 0.197, p=0.013). Similarly, components of MD syndrome suggested an association as well: depression (β= 0.180, p=0.023), anxiety (β= 0.255, p=0.001), and psychoticism (β= 0.188, p=0.018). Conclusions: The results suggest that residents with elevated exposure to environmental Mn have elevated levels of

  4. Teleneonatology: a major tool for the future.

    Minton, Stephen; Allan, Mark; Valdes, Wesley

    2014-02-01

    Hospitals have, for centuries, maintained a central position in the health care system, providing care for critically ill patients. Despite being a cornerstone of health care delivery, we are witnessing the beginning of a major transformation in their function. There are several forces driving this transformation, including health care costs, shortage of health care professionals, volume of people with chronic diseases, consumerism, health care reform, and hospital errors. The neonatal intensive care unit (NICU) at Utah Valley Regional Medical Center in Provo, Utah, began an aggressive redesign/quality improvement effort in 1990. It became obvious that our care processes were designed for health care deliverers and not for the families. An ongoing revamp of our care delivery processes was undertaken using significant input from a parent focus meeting, parental interviews, and development of a parent-to-parent support group. As a result of this work, it became obvious we needed a new model to truly empower parents. The idea of "NICU is Home" was born. We elected to make a mind shift, not to focus on what families think, but rather on how they think. Web cams and other video apparatus have been used in a number of NICUs across the country. We decided our equipment requirements would need to include high-resolution cameras, full high-definition video recording, autofocus, audio microphones, automatic noise reduction, and automatic low-light correction. Our conferencing software needed to accommodate multiple users and have multiple-picture capabilities, low band width, and inexpensive technology. It was recognized that a single video camera feed was insufficient to adequately capture the desired amount of information. Verbal communication between parents and their babies' principal care providers is critical. Parents loved the idea of expanding the remote NICU web cam of their baby to a two-way physician-parent communication bedside monitor. Doctors at Utah Valley

  5. 2016 Status Report on Major Equipment Procurement

    David Perry

    2017-09-01

    Full Text Available The Department of National Defence made some progress in procurement in 2016 despite obstacles that included a continued drop in spending, the advent of a new federal Liberal government and uncertainty over the outcome of the Defence Policy Review. Four trends affected defence acquisitions in 2016. These include an ongoing slippage in recapitalizing the Canadian Armed Forces, some encouraging moves made on the shipbuilding and fighter jet files, mixed progress on implementing the 2014 Defence Procurement Strategy, and uncertainty over the Defence Policy Review. It is also too early to tell how the Trudeau government’s Policy on Results, known as the “deliverology” approach, will play out for defence procurement. However, Budget 2016’s major focus was not on defence, and it shifted some funding for capital equipment to a new endpoint of 2045. This suggests that delay in the overall defence procurement program continues. While the Liberals kept their pledge to make investment in the Royal Canadian Navy a priority, they also made good last year on a negative promise – not to purchase the F-35 stealth fighter bomber. However, further slowing things is the Liberals’ refusal to launch a competition to replace it until the Defence Policy Review is published. The government has made this situation more fraught with its intention to buy 18 Boeing Super Hornet fighter jets as interim aircraft, since Liberal policy requires the Royal Canadian Air Force to be capable of meeting both NORAD’s and NATO’s operational needs simultaneously. Prior to the release of the new defence policy, both the interim and permanent fighter aircraft projects lacked adequate funding. They were among several large projects that have been approved, but have not yet moved to the contract stage, and whose budgets were inadequate to move forward. Adding to this mix is the fact that a government-wide effort initiated in 2014 to streamline the defence procurement

  6. Major advances in applied dairy cattle nutrition.

    Eastridge, M L

    2006-04-01

    Milk yield per cow continues to increase with a slower rate of increase in dry matter intake; thus, efficiency of ruminal fermentation and digestibility of the dietary components are key factors in improving the efficiency of feed use. Over the past 25 yr, at least 2,567 articles relating to ruminant or dairy nutrition have been published in the Journal of Dairy Science. These studies have provided important advancements in improving feed efficiency and animal health by improving quality of feeds, increasing feedstuff and overall diet digestibility, better defining interactions among feedstuffs in diets, identifying alternative feed ingredients, better defining nutrient requirements, and improving efficiency of ruminal fermentation. The publications are vital in continuing to make advancements in providing adequate nutrition to dairy cattle and for facilitating exchange of knowledge among scientists. Forages have been studied more extensively than any other type of feed. Cereal grains continue to be the primary contributors of starch to diets, and thus are very important in meeting the energy needs of dairy cattle. Processing of cereal grains has improved their use. Feeding by-products contributes valuable nutrients to diets and allows feedstuffs to be used that would otherwise be handled as wastes in landfills. Many of these by-products provide a considerable amount of protein, nonforage fiber, fat, and minerals (sometimes a detriment as in the case of P) to diets. The primary feeding system today is the total mixed ration, with still considerable use of the pasture system. Major improvements have occurred in the use of protein, carbohydrates, and fats in diets. Although advancements have been made in feeding practices to minimize the risk of metabolic diseases, the periparturient period continues to present some of the greatest challenges in animal health. Computers are a must today for diet formulation and evaluation, but fewer software programs are developed by

  7. Keynote on lessons from major radiation accidents

    Ortiz, P.; Oresegun, M.; Wheatley, J.

    2000-01-01

    Generic lessons have been learned from a relatively large number of accidents in the most relevant practices (a set of analysis have been made on about 90 radiotherapy events, 43 industrial radiography and nine from industrial irradiations); more specific lessons have been drawn from in-depth investigations of individual accidents. The body of knowledge is grouped as follows: a) radiotherapy is very unique in that humans (patients) are purposely given very high radiation doses (20-75 Gy) by placing them in the radiation beam or by placing radioactive sources in contact with tissues. Intended deterministic effects are the essence of the normal radiotherapy practice and relatively small deviation from the intended doses, i.e,, slightly higher or lower than intended may cause increased rate of severe complication or reduce probability of cure. Consequences of major accidents have been devastating, affecting tens, even hundreds of patients and causing death (directly or indirectly) to a large number of them; b) accidents involving industrial radiography are the most frequent cause of overexposure to workers (radiographers); c) accidents with industrial irradiators have lower probability of occurrence, however, they are deemed to be fatal, especially when whole body exposure to panoramic gamma irradiators occur; partial body irradiation from industrial or research accelerator beams has led to amputation of hands and legs; d) when control of sources was relinquished ('orphan' sources) this has resulted in severe injuries, in some cases death and widespread contamination of the environment. A tool for further dissemination of lessons will be an international reporting system of unusual radiation events (RADEV), being introduced world-wide. Accidents were rarely due to a single human error or isolated equipment failure. In most cases there was a combination of elements such as: a) unawareness of the potential for an accident, b) poor education, which usually did not

  8. Mammography screening: A major issue in medicine.

    Autier, Philippe; Boniol, Mathieu

    2018-02-01

    Breast cancer mortality is declining in most high-income countries. The role of mammography screening in these declines is much debated. Screening impacts cancer mortality through decreasing the incidence of number of advanced cancers with poor prognosis, while therapies and patient management impact cancer mortality through decreasing the fatality of cancers. The effectiveness of cancer screening is the ability of a screening method to curb the incidence of advanced cancers in populations. Methods for evaluating cancer screening effectiveness are based on the monitoring of age-adjusted incidence rates of advanced cancers that should decrease after the introduction of screening. Likewise, cancer-specific mortality rates should decline more rapidly in areas with screening than in areas without or with lower levels of screening but where patient management is similar. These two criteria have provided evidence that screening for colorectal and cervical cancer contributes to decreasing the mortality associated with these two cancers. In contrast, screening for neuroblastoma in children was discontinued in the early 2000s because these two criteria were not met. In addition, overdiagnosis - i.e. the detection of non-progressing occult neuroblastoma that would not have been life-threatening during the subject's lifetime - is a major undesirable consequence of screening. Accumulating epidemiological data show that in populations where mammography screening has been widespread for a long time, there has been no or only a modest decline in the incidence of advanced cancers, including that of de novo metastatic (stage IV) cancers at diagnosis. Moreover, breast cancer mortality reductions are similar in areas with early introduction and high penetration of screening and in areas with late introduction and low penetration of screening. Overdiagnosis is commonplace, representing 20% or more of all breast cancers among women invited to screening and 30-50% of screen

  9. Major intrinsic proteins (MIPs) in plants: a complex gene family with major impacts on plant phenotype.

    Forrest, Kerrie L; Bhave, Mrinal

    2007-10-01

    The ubiquitous cell membrane proteins called aquaporins are now firmly established as channel proteins that control the specific transport of water molecules across cell membranes in all living organisms. The aquaporins are thus likely to be of fundamental significance to all facets of plant growth and development affected by plant-water relations. A majority of plant aquaporins have been found to share essential structural features with the human aquaporin and exhibit water-transporting ability in various functional assays, and some have been shown experimentally to be of critical importance to plant survival. Furthermore, substantial evidence is now available from a number of plant species that shows differential gene expression of aquaporins in response to abiotic stresses such as salinity, drought, or cold and clearly establishes the aquaporins as major players in the response of plants to conditions that affect water availability. This review summarizes the function and regulation of these genes to develop a greater understanding of the response of plants to water insufficiency, and particularly, to identify tolerant genotypes of major crop species including wheat and rice and plants that are important in agroforestry.

  17. A Student's Guide to Einstein's Major Papers

    Janssen, Michel

    2013-01-01

    The core of this volume is formed by four chapters (2–5) with detailed reconstructions of the arguments and derivations in four of Einstein's most important papers, the three main papers of his annus mirabilis 1905 (on the light quantum, Brownian motion, and special relativity) and his first systematic exposition of general relativity of 1916. The derivations are given in sufficient detail and in sufficiently modernized notation (without any serious distortion of the originals) for an undergraduate physics major to read and understand them with far less effort than it would take him or her to understand (English translations of) Einstein's original papers. Each of these four papers is accompanied by a detailed introduction, which covers the conceptual development of the relevant field prior to Einstein's contribution to it and corrects some of the myths surrounding these papers that still have not been fully eradicated among physicists. (One quibble: though Kennedy correctly points out that the goal of the light quantum paper was not to explain the photoelectric effect, it is also not quite right to say that 'it was written to explain the Wien region of blackbody radiation' (p. xv). Einstein used this explanatory feat as the central argument for his light quantum hypothesis.) These four chapters then are the most valuable part of the volume. They could be used, independently of one another, but preferably in conjunction with Einstein's original texts, in courses on quantum mechanics, statistical mechanics, electrodynamics, and general relativity, respectively, to add a historical component to such courses. As a historian of science embedded in a physics department who is regularly called upon to give guest lectures in such courses on the history of their subjects, I can highly recommend the volume for this purpose. However, I would not adopt this volume as (one of) the central text(s) for a course on the history of modern physics. For one thing, chapter 1, which

    Lushnikova, A. V.

    In the article material from various cultural and linguistic sources (Indo-European - Slavic, Indo-Iranian; Uralo-Altaic, Tungus, Ancient Egyptian, Babylonian) is used in order to trace up the chronology of the designation of Ursa Majopr, a constellation which has been playing an important role for people different regions since ancient times. It was used for observing of the visible yearly motion of the Sun, for working out seasonal changes; being a circumpolar and non-hiding behind the horizon it has been perceived as a symbol of immortality, its peculiar positional change during a year lay down in plot of the Uralo-Siberian myths about a cosmic hunt for the Elk, myths about deluge. Data from Uralo-Siberian mythology are analyzed. Designations of Ursa Major in the form of a horned hoofed animal such as elk, deer, cow (Uralo-Altaic, Tungus, Slavic, Indo-Iranian languages; Ancient Greece, Crete, Ancient Egypt) and connected with it (or derived from it) denominations and images of "enclosed space" - "vehicle for travelling and carrying goods" (a wagon, a boat) - "instrument for hunting-fishing, a ritual thing" - "household construction" are taken in consideration. The conclusion is made that the transition of the Ursa Major designation from elk to bear could follow the general tendency to shift from so-called matriarchy to patriarchy, to substitute female deities with male ones, which was reflected "in the rise" of the predatory animal cults (not earlier than II mil. B.C.). To prove this, lexical examples of resemblance and coincidences in designation of homed hoofed (elk, deer) and predatory (bear, wolf) animals should be analyzed. Such a goal-directed investigation of the chronology of Ursa Major designations has never been carried out.

    Major workplace related accidents pose a significant healthcare resource challenge in Singapore. Our study looks at the epidemiology of patients who were admitted for workplace related accidents, in a single institution, with an Injury Severity Score of >9. There were 196 cases of major workplace related accidents admitted between January 2006 and December 2007. The median age of patients admitted was 37 years with a large percentage being males (95.4%) and non-residents (57.1%). The most common ethnic group was Chinese (53.1%) followed by Indians (23.5%). The most common mechanism of injury was fall from height (66.3%) followed by injuries as a result of falling objects at work (21.9%). The percentage of patients who required surgical intervention was 69.9%. Patients admitted for major workplace related accidents had a median length of stay of 5 days in the hospital, a median length of 24 days of medical leave (ML), certifying them unfit for duty and the average cost of stay for each patient was S$11,000. We have a better understanding of the epidemiology and socio-economic impact of workplace related accidents through this study. Workplace related accidents result in significant number of man-days lost from work and monetary cost to employers, medical insurance and the hospital. With an improved understanding, we propose methods to prevent and reduce such accidents in future. A direct consequence of which will be the possible reduction of hospitalisation costs and better allocation of healthcare resources in the future.

  20. Complex mating behavior in Adelosgryllus rubricephalus (Orthoptera, Phalangopsidae, Grylloidea Comportamento Complexo de Acasalamento em Adelosgryllus rubricephalus (Orthoptera, Gryllidae

    2008-09-01

    Full Text Available We describe the mating behavior of Adelosgryllus rubricephalus Mesa & Zefa, 2004. In trials carried out in laboratory we verified the following mating sequence: (1 sexual recognition by antennation; (2 courtship with male turning his abdomen towards the female, performing mediolateral antennae vibration, jerking its body antero-posteriorly and stridulating intermittently, while receptive female drums on the male's abdomen tip, cerci and hind-tibia with her palpi or foretarsi; the male then stops and stays motionless for some seconds, extrudes the spermatophore and both restart the behavioral sequence described above; (3 copulation: male underneath female; with his tegmina inclined forward, and joins his genitalia to the female's to promote sperm transference ; the female steps off the male, occurring a brief end-to-end position; (4 postcopulation: without guarding behavior; male retains the spermatophore and eats it. We quantified elapsed time of each behavioral sequence and discussed its implications in the observed mating behavior.Descrevemos o comportamento reprodutivo de Adelosgryllus rubricephalus Mesa & Zefa, 2004. Em observações realizadas em laboratório verificamos a seguinte seqüência no comportamento de acasalamento: (1 reconhecimento sexual por antenação; (2 corte, em que o macho volta seu abdômen em direção à fêmea, vibra as antenas médio-lateralmente, treme o corpo ântero-posteriormente e estridula intermitentemente, enquanto a fêmea receptiva toca a ponta do abdômen, os cercos e os fêmures posteriores do macho, com seus palpos ou tarsos anteriores; o macho então fica imóvel por alguns segundos, expõe o espermatóforo e ambos retomam a seqüência comportamental descrita acima; (3 cópula: o macho coloca-se sob a fêmea, com suas tégminas inclinadas para frente, anexa sua genitália à dela e promove a transferência do esperma; a fêmea desce de cima do macho e ocorre brevemente a posição "end-to-end" durante a separação do casal; (4 pós-cópula: não há comportamento de guarda; o macho retém o espermatóforo e o ingere. Quantificamos o intervalo de tempo das principais etapas do acasalamento e discutimos suas possíveis implicações no comportamento observado.

  17. Female STEM majors wanted: The impact of certain factors on choice of a college major

    Conrad, Walter Michael

    Although females have made significant strides in educational achievements and substantial inroads into academic majors, such as business and medicine, they have made considerably less progress in the science, technology, engineering, and math (STEM) fields. This translates into a smaller number of female graduates prepared to work in the science career fields and results in American industry looking to other countries for its educated workforce. A mixed-methods research design was used to explore and understand the lived experiences and perceptions of faculty members and working STEM professionals in Northern and Central Virginia. Results indicated that although females are attaining STEM degrees and entering STEM fields in record numbers, obstacles such as a challenging STEM curriculum, bias, feelings of insecurity, lack of female role models, and inadequate preparation for the STEM workforce could impede the progress females have made. This research makes recommendations to the academic community and industry which may be used as retention and recruitment strategies for females considering a career in STEM. The ultimate goal is to significantly increase the number of highly skilled female graduates entering STEM fields, leading the U.S. to regain its previous position atop the world in technological innovation and leadership.

  2. Hyalella azteca (Saussure) responses to Coldwater River backwater sediments in Mississippi, USA.

    Knight, Scott S; Lizotte, Richard E; Shields, F Douglas

    2009-10-01

    Sediment from three Coldwater River, Mississippi backwaters was examined using 28 day Hyalella azteca bioassays and chemical analyses for 33 pesticides, seven metals and seven PCB mixtures. Hydrologic connectivity between the main river channel and backwater varied widely among the three sites. Mortality occurred in the most highly connected backwater while growth impairment occurred in the other two. Precopulatory guarding behavior was not as sensitive as growth. Fourteen contaminants (seven metals, seven pesticides) were detected in sediments. Survival was associated with the organochlorine insecticide heptachlor.

  5. Single-locus complementary sex determination in the inbreeding wasp Euodynerus foraminatus Saussure (Hymenoptera: Vespidae).

    Stahlhut, J K; Cowan, D P

    2004-03-01

    The Hymenoptera have arrhenotokous haplodiploidy in which males normally develop from unfertilized eggs and are haploid, while females develop from fertilized eggs and are diploid. Multiple sex determination systems are known to underlie haplodiploidy, and the best understood is single-locus complementary sex determination (sl-CSD) in which sex is determined at a single polymorphic locus. Individuals heterozygous at the sex locus develop as females; individuals that are hemizygous (haploid) or homozygous (diploid) at the sex locus develop as males. sl-CSD can be detected with inbreeding experiments that produce diploid males in predictable proportions as well as sex ratio shifts due to diploid male production. This sex determination system is considered incompatible with inbreeding because the ensuing increase in homozygosity increases the production of diploid males that are inviable or infertile, imposing a high cost on matings between close relatives. However, in the solitary hunting wasp Euodynerus foraminatus, a species suspected of having sl-CSD, inbreeding may be common due to a high incidence of sibling matings at natal nests. In laboratory crosses with E. foraminatus, we find that sex ratios and diploid male production (detected as microsatellite heterozygosity) are consistent with sl-CSD, but not with other sex determination systems. This is the first documented example of sl-CSD in a hymenopteran with an apparent natural history of inbreeding, and thus presents a paradox for our understanding of hymenopteran genetics.

  6. Nesting biology of Trypoxylon (Trypargilum) lactitarse Saussure (Hymenoptera, Crabronidae) in trap-nests in Southern Brazil.

    Buschini, M L T; Niesing, F; Wolff, L L

    2006-08-01

    This study was carried in the Parque Municipal das Araucárias in the municipality of Guarapuava, state of Paraná, Southern Brazil. Three hundred and sixty five nests of T. lactitarse were obtained using trap-nests of 0.7, 1.0, and 1.3 cm in diameter. All of them had similar architecture, regardless of the diameter of the trap-nest. Completed nests consisted of a linear series of brood cells whose average number per nest was of 3.3, 4.0 and 3.6 for the nests with 0.7 cm, 1.0 cm and 1.3 cm in diameter, respectively. They were constructed more often during the summer. T. lactitarse had two types of life cycles: direct development (without diapause), and delayed development (with diapause during winter). Natural enemies included Chrysididae, Sarcophagidae, Dolichopodidae and Ichneumonidae. Out of 1,353 identified spider prey, 1,313 belonged to the Araneidae family.

  7. Patterns of prey selection of Trypoxylon (Trypargilum) lactitarse Saussure (Hymenoptera: Crabronidae) in southern Brazil.

    Buschini, M L T; Borba, N A; Brescovit, A D

    2008-08-01

    This study was carried out in the Parque Municipal das Araucárias, in the municipality of Guarapuava, southern Brazil. A total of 449 T. lactitarse nests were collected using trap-nests of different diameters. Fifty three species of spiders belonging to 7 families were captured by T. lactitarse. Araneidae was the most captured family and has been strongly represented by the genus Eustala. Through Bray-Curtis's coefficient and the unweighted pair group method average (UPGMA), the spiders species can be divided into 3 groups: the smaller group includes the most abundant species (Eustala sp1, Eustala sp2, Acacesia villalobosi, Alpaida sp1 and Araneus corporosus), the second group includes species with intermediate abundance (Wagneriana iguape, Araneus omnicolor, Eustala sp4, Alpaida grayi, Eustala sp3, Larinia t-notata, Mangora sp1 and Wagneriana iguape), and the third and largest group includes the least abundant species (Aysha gr. brevimana 1, Eustala sp5, Wagneriana eupalaestra, Alpaida scriba, Alpaida veniliae, Araneus aff. omnicolor, Araneus sicki, Eustala sp8, Mangora sp2, Mangora sp3, Wagneriana juquia, Alpaida sp2, Araneus blumenau, Eustala sp6, Eustala sp7 and Ocrepeira galianoae). Of 2,029 identified spiders, 1,171 were captured in the Araucaria forest, 612 in grassland areas and 246 in the swamp. Grassland and swamp areas evidenced greater similarity between them than to the Araucaria Forest, regarding presence-absence of spider species in T. lactitarse's diet, as well as regarding species abundance in these habitats. The juvenile number (56%) was significantly higher than the female (38%) and male (6%) percentages.

  9. Two new bradykinin-related peptides from the venom of the social wasp Protopolybia exigua (Saussure).

    Mendes, Maria Anita; Palma, Mario Sergio

    2006-11-01

    Two bradykinin-related peptides (Protopolybiakinin-I and Protopolybiakinin-II) were isolated from the venom of the social wasp Protopolybia exigua by RP-HPLC, and sequenced by Edman degradation method. Peptide sequences of Protopolybiakinin-I and Protopolybiakinin-II were DKNKKPIRVGGRRPPGFTR-OH and DKNKKPIWMAGFPGFTPIR-OH, respectively. Synthetic peptides with identical sequences to the bradykinin-related peptides and their biological functions were characterized. Protopolybiakinin-I caused less potent constriction of the isolated rat ileum muscles than bradykinin (BK). In addition, it caused degranulation of mast cells which was seven times more potent than BK. This peptide causes algesic effects due to the direct activation of B(2)-receptors. Protopolybiakinin-II is not an agonist of rat ileum muscle and had no algesic effects. However, Protopolybiakinin-II was found to be 10 times more potent as a mast cell degranulator than BK. The amino acid sequence of Protopolybiakinin-I is the longest among the known wasp kinins.

  10. The place of human values in the language of science: Kuhn, Saussure, and structuralism.

    Psaty, B M; Inui, T S

    1991-12-01

    The current paradigm in medicine generally distinguishes between genetic and environmental causes of disease. Although the word "paradigm" has become a commonplace, the theories of Thomas Kuhn have not received much attention in the journals of medicine. Kuhn's structuralist method differs radically from the daily activities of the scientific method itself. Using linguistic theory, this essay offers a structuralist reading of Thomas Kuhn's The Structure of Scientific Revolutions. Our purpose is to highlight the similarities between these structuralist models of science and language. In part, we focus on the logic that enables Kuhn to assert the priority of perception over interpretation in the history of science. To illustrate some of these issues, we refer to the distinction between environmental and genetic causes of disease. While the activity of scientific research results in the revision of concepts in science, the production of significant differences that shape our knowledge is in part a social and linguistic process.

    Full Text Available The continuous improvements in order to optimize the basic education to higher education are still running. Based on that purpose, there are many factors to supporting the students' learning activities success; one of the factors is suitability with majors in university. The purpose of this study is to reveal the condition of the compatibility of students majoring with their interest, then to describe the information when the student choose their majoring. Samples in this study were 122 peoples, taken by random sampling from the Padang State University. Data obtained by distributing questionnaires. The results showed that there are students that their major do not match with their interest (22.13%, only 3.28% of students who feel compatible with their major. This result should be a major concern, particularly for counselor in schools for design counseling services to solve these problems.

    Long-term exposure to traffic pollution has been associated with adverse health outcomes in children and adolescents. A significant number of schools may be located near major roadways, potentially exposing millions of children to high levels of traffic pollution, but this hypothesis has not been evaluated nationally. We obtained data on the location and characteristics of 114,644 US public and private schools, grades prekindergarten through 12, and calculated their distance to the nearest major roadway. In 2005-2006, 3.2 million students (6.2%) attended 8,424 schools (7.3%) located within 100 m of a major roadway, and an additional 3.2 million (6.3%) students attended 8,555 (7.5%) schools located 100-250 m from a major roadway. Schools serving predominantly Black students were 18% (95% CI, 13-23%) more likely to be located within 250 m of a major roadway. Public schools eligible for Title I programs and those with a majority of students eligible for free/reduced price meals were also more likely to be near major roadways. In conclusion, 6.4 million US children attended schools within 250 m of a major roadway and were likely exposed to high levels of traffic pollution. Minority and underprivileged children were disproportionately affected, although some results varied regionally.

  6. A break-even analysis of major ear surgery.

    Wasson, J D; Phillips, J S

    2015-10-01

    To determine variables which affect cost and profit for major ear surgery and perform a break-even analysis. Retrospective financial analysis. UK teaching hospital. Patients who underwent major ear surgery under general anaesthesia performed by the senior author in main theatre over a 2-year period between dates of 07 September 2010 and 07 September 2012. Income, cost and profit for each major ear patient spell. Variables that affect major ear surgery profitability. Seventy-six patients met inclusion criteria. Wide variation in earnings, with a median net loss of £-1345.50 was observed. Income was relatively uniform across all patient spells; however, theatre time of major ear surgery at a cost of £953.24 per hour varied between patients and was the main determinant of cost and profit for the patient spell. Bivariate linear regression of earnings on theatre time identified 94% of variation in earnings was due to variation in theatre time (r = -0.969; P break-even time for major ear surgery of 110.6 min. Theatre time was dependent on complexity of procedure and number of OPCS4 procedures performed, with a significant increase in theatre time when three or more procedures were performed during major ear surgery (P = 0.015). For major ear surgery to either break-even or return a profit, total theatre time should not exceed 110 min and 36 s. © 2015 John Wiley & Sons Ltd.
