Bonde SR, Gade AK, Rai MK. 2012. Genetic diversity among fourteen different Fusarium species using RAPD marker. Biodiversitas 14:Â 55-60. We report genetic diversity of total fourteen different Fusarium species by RAPD-PCR analysis using 25 random primers. TheÂ genus Fusarium is food borne pathogen responsible for T-2 toxin production which affects human and animal health. In the presentÂ study, total 14-different species of Fusarium were analyzed on the basis of genetic diversity using RAPD method. A dendrogram wasÂ developed by UPGMA method. RAPD analysis was carried out by using 25 different universal primers each of them consisted of 10Â bases. Genetic similarity coefficients between pair wise varied from 0.00 to 0.9 based on an unweighted paired group method ofÂ arithmetic average (PGMA) cluster analysis. RAPD-PCR technique can be used as an important tool for the genetic differentiation Fusarium species.

Tapwal A, Kumar R, Pandey S. 2013. Diversity and frequency of macrofungi associated with wet ever green tropical forest in Assam,Â India. Biodiversitas 14: 73-78. A study was conducted in Jeypore Reserve Forest located in Assam, India to investigate the diversity ofÂ macrofungi associated with different tree species. The diversity of broad leaves trees and high humidity during monsoon period favoursÂ ideal growth of diverse group of macrofungal fruiting bodies. Thirty macrofungal species representing 26 genera belonging to 17Â families were collected from six different sites in the study area. Out of these maximum six genera assignable to family Polyporaceae,Â five genera to Russulaceae, three genera to Agaricaceae, two genera to Ganodermataceae and Cantharellaceae each and rest of theÂ families were represented by single genus only. The ecological preference of the species reveled that maximum (17) species wereÂ saprophyte, living on dead substrates or decaying wood debris, ten species were found associated with roots of higher trees, while threeÂ species were found parasitic. Overall 20 species were found edible including some species having medicinal utilization. The presentÂ study revealed that maximum frequency of occurrence was exhibited by Trametes versicolor and Schizophyllum commune (83.33%),Â followed by Microporus xanthopus, Pycnoporus sanguineus (66.67%)Â and Coprinus disseminates (50%). The rest of the speciesÂ exhibited the frequency distribution ranging between 16.67-33.33%. The maximum density was recorded for Schizophyllum commune (126.67%)Â followed by Trametes versicolor (120%)Â and Xylaria polymorpha (93.33%). The density of rest of the species were ranged between 3.33- 6.67%. The key objective of the present study was to generate a database on macrofungal diversity of Jeypore Reserve Forest along with their ecological preferences and utilization, which is not earlier documented.

Bazdid Vahdati F, Saeidi Mehrvarz Sh, Naqinezhad A, Gholizadeh H. 2014. How plant diversity features change across ecologicalÂ species groups? A case study of a temperate deciduous forest in northern Iran. Biodiversitas 15: 31-38. Species diversity is one of theÂ most important indices for evaluating the stability and productivity of forest ecosystems. The aim of this research was to recognizeÂ ecological species groups and to determine the relationship between environmental variables and the distribution of ecological speciesÂ groups. For this purpose, 25 400-mÂ 2Â relevÃ©s were sampled using the Braun-Blanquet method. Vegetation was classified using modifiedÂ Two-Way Indicator Species Analysis (TWINSPAN) and resulted in three ecological species groups. Different species diversity indicesÂ were applied to quantify diversity of these species groups. ANOVA and Duncanâ€™s tests indicated that all species and environmentalÂ variables except altitude changed significantly across the species groups. The results also showed that the group located in the northernÂ aspect and on low slopes had the highest diversity indices compared with groups located in dry aspects and on high slopes. In reality,Â abundant precipitation (northern aspect)Â and soil enrichment (low slopes) are principal factors that provide suitable conditions for plantÂ growth and species diversity. Thus, the study of diversity changes in ecological species groups can result in an ecologically preciseÂ perspective for managing forest ecosystems.

Three specimens of Giganthias immaculatus Katayama, 1954, were collected from Bitung, NorthÂ Sulawesi, in October 2009, November 2009 and June 2012. The morphological data for G. immaculatus are similar to those for G.Â serratospinosus White & Dharmadi, 2012; those species share the following characters: dorsal fin rays IX, 11-13, anal fin rays III, 8 andÂ lateral line high arched. However, the former is clearly distinguishable from G. serratospinosus by pectoral-fin rays 16 or 17 (vs. 13 orÂ 14 for G. serratospinosus);Â ill rakers (10) + (21-24) (vs. 10+20Â or G. serratospinosus). It also differs in the following: body depth,Â head length, predorsal length, preanal length, upper-jaw length, interorbital width. Initially, this species was collected from Izu-Ã•shima,Â Japan. Other localities of capture for this species are: Ago Bay, Shimacho Goza, Shima City, Mie Pref., Tomari, Okinawa, Japan andÂ Taiwan and now recorded also off Bitung, Sulawesi Island, Indonesia.
Co-Sorption of Cd and Phosphate on the Surface of a Synthetic Hydroxyiron-Montmorillonite Complex
Authors: Zhu Runliang , Li Min , Ge Fei , Xu Yin , Zhu Jianxi , He Hongping
Published: July 2014

Hydroxymetal-clay complexes, which contain reactive surface hydroxyl groups, have a strong affinity for both heavy-metal cations and oxyanions and hence can serve as efficient sorbents for ionic contaminants. The co-sorptive behavior of heavy-metal cations and oxyanions on the surface of hydroxymetal-clay complexes is not well understood, however. The objective of the present investigation was to help bridge that gap by determining the feasibility of co-sorbing Cd cations and phosphate from aqueous solution to a hydroxyiron-montmorillonite complex (HyFe-mont). A montmorillonite-rich clay from Inner Mongolia, China, was the starting material. The results showed that Cd and phosphate could be sorbed, simultaneously and synergistically, to HyFe-mont without a change in solution pH. Similarly, when phosphate was sorbed before Cd, the sorption capacities were comparable to those obtained in the simultaneous sorption experiment, and the solution pH did not change.When Cd was pre-sorbed, however, the subsequent sorption of both Cd and phosphate decreased as did solution pH. X-ray photoelectron spectroscopy (XPS) indicated that the binding energies of P2p, Cd3/2, and Cd5/2 were of similar magnitude for both the simultaneous sorption system and the phosphate pre-sorbed system. In addition, the single Cd and Cd pre-sorbed systems had similar Cd3/2 and Cd5/2 binding energies. The combined sorption and XPS results suggested that sorbed phosphate and Cd formed P-bridged ternary complexes on the HyFe-mont surface, contributing to the synergistic uptake of the contaminants in the simultaneous sorption system.
Walking on the margins: From Italian Neorealism to contemporary Chinese Sixth Generation
Authors: Lu Jie
Published: July 2014

This article aims to examine the Sixth Generation films of contemporary China through the lens of Italian Neorealism: particularly, their moral commitments and aesthetic innovations. Along with many international art films, the Sixth Generation films share a realist impulse that was most innovatively pioneered and explored in Italian Neorealism. In every case, the film-maker is attempting to chronicle the present by focusing generally on the dark side of reality and specifically on the life lived by disenfranchised people. The goal is to create an anti-illusionist film culture that helps viewers to see and reflect upon this reality first from within and then beyond cinema. Selecting Xiao Shan Going Home (Jia, Zhangke, 1995) and Still Life (Jia, Zhangke, 2006) by Jia Zhangke as representative of the Sixth Generation, this article details how such films adopt Italian neorealist conventions (such as long takes, long shots with deep focus and location shooting) and thereafter expand these formal elements to underscore social contradictions behind the glamour of Chinese economic development so as to present a more complete sense of modernity.

The Real Effects of Military Spending on Security
Authors: Dumas Lloyd J.
Published: July 2014

The indirect effects of military spending on security are stronger and more important than its direct effects, and its long run impact more telling than its short run impact. In the short run, military spending can be a source of both physical security and economic stimulus. In the long run, it can be counterproductive in terms of physical security and will be a dead weight on the economy. How a society’s productive resources are deployed, as between military spending and more economically productive activities, sets it on a long-term course with powerful implications for the ability of its economy to do what it is supposed to do – provide for the material well-being of the population as a whole. The mechanism by which the extensive and extended diversion of productive economic resources to economically unproductive military spending drags an economy down is analyzed. Furthermore, it is possible to use properly structured international and domestic economic relationships in place of threats or use of military force to increase national and international security, while at the same time enhancing, rather than degrading, economic wellbeing. Three principles for structuring such a “peacekeeping economy” are set forth.

Plasma high‐density lipoprotein (HDL) levels show a strong inverse correlation with atherosclerotic vascular disease. Previous studies have demonstrated that antagonism of miR‐33 in vivo increases circulating HDL and reverse cholesterol transport (RCT), thereby reducing the progression and enhancing the regression of atherosclerosis. While the efficacy of short‐term anti‐miR‐33 treatment has been previously studied, the long‐term effect of miR‐33 antagonism in vivo remains to be elucidated. Here, we show that long‐term therapeutic silencing of miR‐33 increases circulating triglyceride (TG) levels and lipid accumulation in the liver. These adverse effects were only found when mice were fed a high‐fat diet (HFD). Mechanistically, we demonstrate that chronic inhibition of miR‐33 increases the expression of genes involved in fatty acid synthesis such as acetyl‐CoA carboxylase (ACC) and fatty acid synthase (FAS) in the livers of mice treated with miR‐33 antisense oligonucleotides. We also report that anti‐miR‐33 therapy enhances the expression of nuclear transcription Y subunit gamma (NFYC), a transcriptional regulator required for DNA binding and full transcriptional activation of SREBP‐responsive genes, including ACC and FAS. Taken together, these results suggest that persistent inhibition of miR‐33 when mice are fed a high‐fat diet (HFD) might cause deleterious effects such as moderate hepatic steatosis and hypertriglyceridemia. These unexpected findings highlight the importance of assessing the effect of chronic inhibition of miR‐33 in non‐human primates before we can translate this therapy to humans.

For many decades, elevated androgens in women have been associated with poor reproductive health. However, recent studies have shown that androgens play a crucial role in women's fertility. The following review provides an overall perspective about how androgens and androgen receptor-mediated actions regulate normal follicular development, as well as discuss emerging concepts, latest perceptions, and controversies regarding androgen actions and signaling in the ovary.
Fabrication and Characterization of Chitosan/Cellulose-ZnO Nanocomposites for Bactericidal Applications
Authors: Pérez-Altamar Melina , Perales-Pérez Oscar
Published: July 2014

The present work focuses on the fabrication of environmental friendly ZnO nanocrystals and chitosan/cellulose films hosting ZnO nanoparticles (NPs) as an attempt to produce nanocomposites with enhanced bactericidal capacity. The solution casting method was used to fabricate the chitosan/cellulose blend films. Highly monodisperse ZnO nanoparticles were synthesized using Zinc acetate and Triethylene glycol (TEG) via a modified Polyol route. ZnO crystal size was controlled by the heterogeneous nucleation approach. Optical properties of ZnO nanoparticles were studied by UV–vis spectroscopy and Photoluminescence Spectroscopy (PL) techniques. The nanoparticles’ size and morphology were determined by Transmission Electron Microscopy (TEM) and X-ray diffraction (XRD), respectively. Obtained results confirmed the effectiveness of the size-controlled synthesis employed. The chitosan/cellulose/ZnO nanocomposites were characterized by Fourier Transform – Infrared spectroscopy (FTIR) and X-ray diffraction (XRD) methods. The mechanical properties of produced bare and ZnO-bearing composites were determined from stress-strain tests. The Standard Plate Count and the Halo Zone methods were used to evaluate the bactericidal properties of the ZnO nanoparticles, chitosan/cellulose blend films and chitosan/cellulose/ZnO nanocomposites againstEscherichia coli(ATCC 35218).

Published: July 2014

Este estudo explora o guānxì como discurso organizacional vigente na cultura de negócios nas organizações chinesas a partir da lógica da equivalência e da lógica da diferença propostas por Ernesto Laclau e Chantal Mouffe. O guānxì consiste em um relacionamento interpessoal e na criação de conhecimento colaborativo que envolve um saber tácito, orientado para o futuro, complexo que opera em contexto específico. Em uma perspectiva pós-estruturalista aplicada às organizações, utilizamos a análise de discurso como método que permite pôr em prática o papel da linguagem na condição de eixo de compreensão de processos sociais, como acontece com o guānxì. Analisamos 3 entrevistas em profundidade realizadas com chief executive officers (CEOs) chineses e 32 reportagens relacionadas à prática do guānxì em organizações do setor terciário, publicadas em 2 dos maiores diários digitais da China. Com isso, nosso objetivo foi identificar a forma como esse fenômeno tem sido apropriado como discurso no âmbito organizacional a partir da lógica da equivalência e da lógica da diferença. Constatamos que as organizações chinesas utilizam o guānxì para obterem acesso preferencial a atores estratégicos que têm informações e recursos demandados nos processos negociais, com vista a obterem vantagens competitivas. Por outro lado, o sucesso dos negócios envolvendo essas organizações depende de uma identificação mútua entre seus líderes, baseada na confiança e credibilidade estabelecidas nas articulações.

Authors: Mac Cord Marcelo
Published: July 2014

O artigo explora as experiências do mestre pedreiro e homem pardo Francisco José Gomes de Santa Rosa, que viveu entre os anos de 1810 e 1861. Por meio de livros de associações de artífices especializados e de seu inventário, entre outros documentos, que foram compulsadas nos mais diferentes arquivos recifenses, observamos que o trabalhador foi homem livre, pernambucano, casado, proprietário de alguns imóveis e ganhou destaque em duas organizações dedicadas aos profissionais de seu ofício. Por conta de suas redes de clientela, de seu destaque junto à classe artística e do reconhecimento público de sua perícia, José Francisco Gomes de Santa Rosa alcançou alguma instrução, acumulou cabedal e constituiu uma boa rede de relações. No final de sua vida, contudo, por conta de uma doença crônica e da manutenção de seu padrão de vida (à custa do esgotamento de seus recursos), o artesão de pele escura deixou sua família materialmente desamparada.
Cucumbis Carnavalescos: Áfricas, carnaval e abolição (Rio de Janeiro, década de 1880)
Authors: Brasil Eric
Published: July 2014

Este artigo apresenta uma pesquisa sobre os Cucumbis Carnavalescos. Esses grupos alcançaram a sua maior notoriedade na segunda metade da década de 1880, aparecendo cada vez mais nos jornais e conquistando seu espaço nas ruas durante os dias de carnaval. Eles foram reconhecidos, por jornalistas e outros observadores contemporâneos, como "africanos" - "danças africanas", "instrumentos africanos" e "trajes africanos" - desfilando pelas ruas da cidade. O objetivo principal deste trabalho é tentar entender os possíveis significados por trás do ato de criar, preservar e transformar uma ação festiva que tem o passado africano como elemento fundamental para a formação de identidade para os seus membros. Essa identidade africana foi reforçada precisamente enquanto a luta pela abolição da escravatura tornou-se mais intensa e os debates sobre cidadania tornaram-se mais fortes do que nunca.

Published: July 2014

Este estudo procurou analisar a produção científica brasileira 2000-2010 sobre vínculos do empregado com a organização, abrangendo quatro temas principais: comprometimento organizacional, contratos psicológicos, cidadania organizacional e percepções de apoio e de justiça e equidade. Justifica essa escolha a importância dessas questões para o campo de pesquisa micro-organizacional e a intensa concentração de pesquisa sobre o tema. Sessenta e três artigos foram identificados. As análises seguiram três ênfases: aspectos metodológicos; conteúdos dos artigos, suas contribuições e limitações; e as redes de parcerias entre autores e instituições. Os resultados indicam altos níveis de nebulosidade conceitual e de sobreposição de instrumentos, e pouca interação entre grupos de pesquisa. Com base nos resultados, foi proposta uma agenda de pesquisa.

Authors: Matos Daniel Abud Seabra , Leite Walter Lana , Brown Gavin Thomas Lumsden , Cirino Sérgio Dias
Published: July 2014

The Teacher Communication Behavior Questionnaire (TCBQ) has been used at different levels of education in many countries to measure students' perceptions of their science teachers' communication behavior. The TCBQ was translated into Portuguese in accordance with ITC test adaptation standards. Validity evidence for the Brazilian version of the TCBQ was obtained with a sample of 414 secondary students. The internal consistency of the TCBQ was satisfactory and an adequate fit of the original factor model was found through confirmatory factor analysis. The Brazilian data exhibited inter-factor correlations similar in value and direction to those of previous international studies. Statistically significant differences were found between school type and subject matter, which is consistent with previous studies.
A violência no contexto escolar: uma leitura interdisciplinar
Authors: Bispo Fábio Santos , Lima Nádia Laguárdia de
Published: July 2014

Este artigo apresenta uma abordagem interdisciplinar acerca da problemática da violência na escola. Discutem-se, primeiramente, as possíveis definições e caracterizações da violência, tomando-a a partir de diferentes dimensões, tais como a violência subjetiva, a violência simbólica e a violência objetiva, sistêmica ou estrutural. São analisadas as formas simbólicas e sociais da violência institucional que permeia o âmbito escolar, sobretudo a partir de suas relações com a noção foucaultiana de poder disciplinar. Em oposição às crescentes estratégias de controle e segregação articuladas ao biopoder que se fazem presentes no espaço escolar, destacamos a importância de uma educação que valorize a participação ativa dos jovens na construção de saídas para os impasses e conflitos presentes nas relações sociais e pedagógicas, bem como as possíveis contribuições da psicanálise para esse processo.
Autonomia na inserção internacional do Brasil: um caminho histórico próprio
Authors: Saraiva José Flávio Sombra
Published: July 2014

O artigo trata da formação histórica do conceito de autonomia na política externa do Brasil. No contexto dos debates que já se avizinham em torno dos 200 anos do Brasil independente, o artigo argumenta que a inserção internacional do país, em perspectiva evolutiva, deve a formuladores e formulações que, no tempo, conferiram uma acepção própria, brasileira, do entendimento heurístico do conceito de autonomia. O artigo analisa, portanto, a longa duração, as acepções e processos de valorização desse conceito na diplomacia, na sociedade e na discussão dos estudiosos, brasileiros e estrangeiros, que trataram desse tema.
Humanitarismo e a favela global: violência urbana e ação humanitária no Rio de Janeiro
Authors: Moulin Carolina , Tabak Jana
Published: July 2014

O artigo analisa criticamente os dilemas envolvidos nas recentes intervenções de organizações humanitárias internacionais em contextos urbanos do Sul Global. A inclusão de comunidades urbanas pobres - como as favelas do Rio de Janeiro - no escopo de atuação de atores humanitários resulta da compreensão particular que associa processos de urbanização à redefinição dos alvos da ação humanitária. O artigo argumenta que a transposição da proteção e assistência humanitária para outras situações de violência, como as favelas do Rio, está fundamentada na construção de favelas enquanto espaços marginais de insegurança e epítome de todos os problemas relacionados a processos urbanos em sociedades em desenvolvimento e menos desenvolvidas. Baseado em uma análise do projeto da organização Médicos Sem Fronteiras no Complexo do Alemão, no Rio de Janeiro, entre 2007 e 2009, o artigo conclui com uma discussão crítica acerca das consequências do reconhecimento e produção das favelas (e da favela global) como um problema de segurança e proteção, em que dimensões democráticas complexas das disputas políticas locais são silenciadas.
Leituras do império: o poder global dos Estados Unidos reavaliado
Authors: Domingues José Maurício
Published: July 2014

O império dos Estados Unidos segue sendo objeto de atenção das ciências sociais. Obras recentes como as de Mann, bem como de Panitch e Gindin, retomam o tema. Eles apresentam análises amplas de sua origem e desenvolvimento. Mas descuram em parte ao menos das condições culturais des-se poder. Este texto se propõe a refletir sobre isso, indagando também em que medida a própria categoria império serviria para enquadrar esse poder global dos EUA, relacionando-o ademais à ideia de hegemonia. A conclusão nesse sentido é que o poder dos EUA não pode ser enquadrado na categoria tradicional de império, ainda que mantenha elementos que remetam ao que seria o exercício imperial do poder, mas já transformado pelos desdobramentos da modernidade. Uma segunda conclusão aponta para o fato de que o poder externo se calca na própria estruturação interna do poder como hegemonia, na definição de uma forma civilizacional que se projeta para fora, em grande medida com fundamentos culturais, porém também vinculada a padrões econômicos de acumulação e de classe, bem como conjugada às dimensões militares, políticas e jurídicas do poder.
Relações entre a resposta de ansiedade de pais e mães e a reposta de ansiedade de seus filhos
Authors: Nascimento Célia Regina Rangel
Published: July 2014

Este estudo investigou a relação entre as respostas de ansiedade de pais e as respostas de ansiedade de seus filhos, considerando a possibilidade de diferenças de gênero e faixa etária dos filhos nesta relação. Participaram deste estudo 50 crianças e 49 adolescentes, de ambos os sexos, alunos de escolas estaduais de Porto Alegre, e seus pais e mães. Para avaliar a ansiedade das crianças, foi aplicado o Inventário de Ansiedade-traço-Estado para Crianças (IDATE-C). Nos adolescentes, nos pais e nas mães foi aplicado o Inventário de Ansieda-de-traço-Estado (IDATE). Foram feitas correlações de Pearson para verificar as relações entre a ansiedade-traço e estados dos filhos com a ansiedade-traço e estado de seus pais. Os resultados sugerem haver relação entre as respostas de ansiedade dos pais e filhos nas amostras, com diferenças em relação ao gênero e a faixa etária dos filhos.
A reconstrução intercultural dos direitos humanos linguísticos escolares guarani: horizontes sociais e letramento
Authors: Guerola Carlos Maroto
Published: July 2014

O presente artigo busca contribuir para a reconstrução intercultural do direito humano linguístico escolar ao letramento, pondo em questão o caráter monovalente e universalizante com que esse direito é inserido no horizonte social dos grupos dominantes do capitalismo global. À luz de uma fundamentação teórica que articula discursos do Círculo de Bakhtin, dos Novos Estudos de Letramento, da Linguística Aplicada e dos Estudos Culturais, são interpretados, na análise de dados, discursos dos professores da Escola Indígena de Ensino Fundamental Itaty, da aldeia guarani do Morro dos Cavalos (SC). Esses discursos reconstroem interculturalmente o direito ao letramento, em primeiro lugar, como direito ao registro escolar da tradição cultural (reivindicado em decorrência das transformações de base econômica das práticas legitimadas de geração e transmissão de conhecimento da comunidade), e, em segundo lugar, como "arma de defesa e sobrevivência", através da qual lutar por uma maior soberania sobre as próprias formas de enunciação, indissociável de uma maior soberania econômica.
Efficacy and safety of topical eprinomectin to controlMyocoptes musculinus infestation in mice
Authors: Rambozzi Luisa , Rossi Luca , Min Anna Rita Molinar , Osella Luca , Bellardi Sergio , Marchetti Roberto , Pollicino Paolo
Published: July 2014

Myocoptes musculinus is the most common fur mite identified among laboratory mice; infested mice, in addition to dermatological signs, may also be prone to secondary infections, affecting the outcome of a research trial. This trial was conducted in order to assess the safety and efficacy of a single topical administration of eprinomectin (5mg/kg BW) in a naturally infested laboratory mice colony. A safety trial was conducted on 20 uninfested pregnant females assigned to two groups, receiving eprinomectin and mineral oil, respectively. The mice were examined daily for signs of illness or toxicity; nests were individually weighted at 21 and 28 days postpartum. No acute toxicity was observed, all treated females gave full term delivery and number and mean weight of newborns ranged in the physiological values. To evaluate the efficacy, 20 naturally infested non-pregnant females were divided into two groups, treated as in the safety trial. Animals were observed daily for 15 min until 21 days post-treatment (DPT) and a “pruritus index” (PI: scratching and gnawing acts/mouse/min) was calculated. Pelage examination was performed on DPT 7, 14, 21 and 50. The “PI” was significantly lower in the treated group and mites were eradicated from all infested animals. A single topical administration of eprinomectin at a (high) dosage of 5mg/kg BW was safe and effective to control M. musculinusin mice.
The paleoichthyological and geological researches on the Permian deposits of Muse near Autun (Saône-et-Loire, France) at the beginning of the XIXth century
Authors: BRIGNON Arnaud
Published: July 2014

Le gisement Autunien de Muse est célèbre pour ses richesses paléontologiques et notamment pour sa « couche aux poissons » dans laquelle les Aeduellidae (Pisces, Actinopterygii) sont particulièrement abondants. Alors que l’histoire de ce gisement est bien documentée à partir de la fin des années 1830, les premières recherches paléontologiques et géologiques qui y ont été faites avant cette période, restent encore mal connues. Un manuscrit inédit d’Alexander von Humboldt révèle qu’il avait étudié en mars 1805 la géologie de la région d’Autun où il avait reconnu le Zechstein. Un témoignage consigné dans la Feuille du Canton de Vaud permet de faire remonter à l’année 1811 la collecte des premiers spécimens de poissons à Muse. Deux naturalistes et géologues, François-Joseph Lainé et Cyprien Prosper Brard, sont à l’origine de ces découvertes. Dans les années 1820, de nombreux poissons fossiles de Muse furent ensuite collectés par Augustin Henri de Bonnard. Des spécimens d’Aeduella blainvillei (Agassiz, 1833) faisant partie des premières découvertes faites à Muse ont été identifiés dans les collections du Musée cantonal de Géologie à Lausanne et dans celles du Muséum national d’Histoire naturelle, Paris. Cet inventaire a permis de retrouver plusieurs spécimens de la collection Alexandre Brongniart sur lesquelles Henri-Marie Ducrotay de Blainville a établi les espèces « Palaeothrissum inaequilobum » et « Palaeothrissum parvum ». La partie postérieure d’un des spécimens de la série type de « Palaeoniscus voltzii » Agassiz, 1833 qui était considéré comme perdu depuis longtemps, a également été identifiée. Un dessin inédit conservé dans les archives de Cuvier montrant une plaque de schiste de Muse avec deux Aeduella blainvillei est présenté. Cette pièce était conservée dans le Cabinet d’histoire naturelle de Barthélémy Faujas de Saint-Fond. Ce dessin constitue la plus ancienne représentation de poissons fossiles de cette localité réalisée avant les figures publiées en 1833 et 1834 par Louis Agassiz dans ses Recherches sur les poissons fossiles. Les découvertes paléoichthyologiques effectuées à Muse et Igornay par plusieurs personnalités comme Landriot, Selligue et Héricart de Thury dans les années 1830 sont aussi mises en lumière. Pour finir, des documents manuscrits inédits rédigés vers 1824 dévoilent les différentes opinions d’Ami Boué, Alexander von Humboldt et Augustin Henri de Bonnard sur la position stratigraphique des schistes bitumineux de la région d’Autun bien avant que le Permien ne soit créé par le géologue britannique Roderick Impey Murchison en 1841.
Existence of μ-pseudo almost automorphic solutions to a neutral differential equation by interpolation theory
Authors: Chang Yong-Kui , Luo Xiao-Xia
Published: July 2014

In this paper, we shall deal with ?-pseudo almost automorphic solutions to a
neutral differential equation. To achieve this goal, we first prove a
composition theorem for ?-pseudo almost automorphic functions under suitable
conditions, and then apply it to investigate some existence results by the
interpolation theory and fixed point methods.
The Economic Consequences of Financial Restatements: Evidence from the Market for Corporate Control
Authors: Amel-Zadeh Amir , Zhang Yuan
Published: July 2014

This paper investigates whether and how financial restatements affect the market for corporate control. We show that firms that recently filed financial restatements are significantly less likely to become takeover targets than a propensity score matched sample of non-restating firms. For those restating firms that do receive takeover bids, the bids are more likely to be withdrawn or take longer to complete than those made to non-restating firms. Finally, there is some evidence that deal value multiples are significantly lower for restating targets than for non-restating targets. Our analyses suggest that the information risk associated with restating firms is the main driver of these results. Overall, this study finds that financial restatements have profound consequences for the allocation of economic resources in the market for corporate control.

Some global results for nonlinear fourth order eigenvalue problems
Authors: Aliyev Ziyatkhan
Published: July 2014

In this paper, we consider the nonlinear fourth order eigenvalue problem. We show the existence of family of unbounded continua of nontrivial solutions bifurcating from the line of trivial solutions. These global continua have properties similar to those found in Rabinowitz and Berestycki well-known global bifurcation theorems.
Topological tools for the prescribed scalar curvature problem on S n
Authors: Abuzaid Dina , Ben Mahmoud Randa , Chtioui Hichem , Rigane Afef
Published: July 2014

In this paper, we consider the problem of the existence of conformal metrics with prescribed scalar curvature on the standard sphere S n, n ≥ 3. We give new existence and multiplicity results based on a new Euler-Hopf formula type. Our argument also has the advantage of extending well known results due to Y. Li [16].

Super-De Morgan functions and free De Morgan quasilattices
Authors: Movsisyan Yuri , Aslanyan Vahagn
Published: July 2014

A De Morgan quasilattice is an algebra satisfying hyperidentities of the variety of De Morgan algebras (lattices). In this paper we give a functional representation of the free n-generated De Morgan quasilattice with two binary and one unary operations. Namely, we define the concept of super-De Morgan function and prove that the free De Morgan quasilattice with two binary and one unary operations on nfree generators is isomorphic to the De Morgan quasilattice of super-De Morgan functions of nvariables.
Automorphism groups of rational elliptic surfaces with section and constant J-map
Authors: Karayayla Tolga
Published: July 2014

In this paper, the automorphism groups of relatively minimal rational elliptic surfaces with section which have constant J-maps are classified. The ground field is ℂ. The automorphism group of such a surface β: B → ℙ1, denoted by Au t(B), consists of all biholomorphic maps on the complex manifold B. The group Au t(B) is isomorphic to the semi-direct product MW(B) ⋊ Aut σ (B) of the Mordell-Weil groupMW(B) (the group of sections of B), and the subgroup Aut σ (B) of the automorphisms preserving a fixed section σ of B which is called the zero section on B. The Mordell-Weil group MW(B) is determined by the configuration of singular fibers on the elliptic surface B due to Oguiso and Shioda [9]. In this work, the subgroup Aut σ (B) is determined with respect to the configuration of singular fibers of B. Together with a previous paper [4] where the case with non-constant J-maps was considered, this completes the classification of automorphism groups of relatively minimal rational elliptic surfaces with section.
Properties of triangulations obtained by the longest-edge bisection
Authors: Perdomo Francisco , Plaza Ángel
Published: July 2014

The Longest-Edge (LE) bisection of a triangle is obtained by joining the midpoint of its longest edge with the opposite vertex. Here two properties of the longest-edge bisection scheme for triangles are proved. For any triangle, the number of distinct triangles (up to similarity) generated by longest-edge bisection is finite. In addition, if LE-bisection is iteratively applied to an initial triangle, then minimum angle of the resulting triangles is greater or equal than a half of the minimum angle of the initial angle. The novelty of the proofs is the use of an hyperbolic metric in a shape space for triangles.
A maximum degree theorem for diameter-2-critical graphs
Authors: Haynes Teresa , Henning Michael , Merwe Lucas , Yeo Anders
Published: July 2014

A graph is diameter-2-critical if its diameter is two and the deletion of any edge increases the diameter. Let G be a diameter-2-critical graph of order n. Murty and Simon conjectured that the number of edges in G is at most ⌊n 2/4⌋ and that the extremal graphs are the complete bipartite graphs K ⌊n/2⌋,⌊n/2⌉. Fan [Discrete Math. 67 (1987), 235–240] proved the conjecture for n ≤ 24 and for n = 26, while Füredi [J. Graph Theory 16 (1992), 81–98] proved the conjecture for n > n 0 where n 0 is a tower of 2’s of height about 1014. The conjecture has yet to be proven for other values of n. Let Δ denote the maximum degree of G. We prove the following maximum degree theorems for diameter-2-critical graphs. If Δ ≥ 0.7 n, then the Murty-Simon Conjecture is true. If n ≥ 2000 and Δ ≥ 0.6789 n, then the Murty-Simon Conjecture is true.
