Global and regional dispersion of publishing in the field of international marketing

This paper empirically examines the research productivity of academic institutions in the leading international marketing journals, leading generalist marketing journals, and leading international business journals between the years 1999 and 2003 from a regional and country-specific perspective. The research found that across the three groups of journals, the majority of works were authored by academics at institutions located in North America, although North Americans contribute significantly less in the international marketing and international business journals than leading generalist marketing journals. The findings suggest that there is a broadening of non-U.S. influence within the international marketing and international business journals, which should lead to a broadening of international marketing theory.

Estimating the age of juvenile loggerhead sea turtles in the North Atlantic

Analysis of previously published records shows that the modal size of juvenile loggerhead sea turtles (Caretta caretta) found around the United Kingdom (the area north of 49°N and east of 12°W) is a carapace length of 20.5 cm. These turtles are believed to originate from nesting beaches in North America (principally Florida). We estimated their trans-Atlantic drift time using data from satellite-tracked buoys and from a mathematical model and, hence, estimated that the modal age of these juvenile turtles was between 1.80 and 3.75 years.

Terrane transfer during the Grenville orogeny: tracing the Amazonian ancestry of southern Appalachian basement through Pb and Nd isotopes

Whole rock Pb isotope data can be used to determine the provenance of different blocks within the Rodinia supercontinent, providing a test for paleogeographic reconstructions. Calculated isotopic values for the source region of the Grenville-deformed SW Amazon craton (Rondonia, Brazil), anchored by published U-Pb zircon ages, are compared to those from the Grenville belt of North America and Grenvillian basement inliers in the southern Appalachians. Both the SW Amazon craton and the allochthonous Blue Ridge/Mars Hill terrane are defined by a similar Pb isotopic signature, indicating derivation from an ancient source region with an elevated U/Pb ratio. In contrast, the Grenville Province of Laurentia (extending from Labrador to the Llano Uplift of Texas) is characterized by a source region with a distinctly lower, time-integrated U/Pb ratio. Published U-Pb zircon ages (ca. 1.8 Ga) and Nd model ages (1.4-2.2 Ga) for the Blue Ridge/Mars Hill terrane also suggest an ancient provenance very different from the rest of the adjacent Grenville belt, which is dominated by juvenile 1.3-1.5 Ga rocks. The presence of mature continental material in rocks older than 1.15 Ga in the Blue Ridge/ Mars Hill terrane is consistent with characteristics of basement rocks from the SW Amazon craton. High-grade metamorphism of the Blue Ridge/Mars Hill basement resulted in purging of U, consistent with observations of the rest of the North American Grenville province. In contrast, the Grenvillian metamorphic history of the Amazon appears to have been much more heterogeneous, with both U enrichment and U depletion recorded locally. We propose that the Blue Ridge/ Mars Hill portion of the Appalachian basement is of Amazonian provenance and was transferred to Laurentia during Grenvillian orogenesis after similar to1.15 Ga. The presence of these Amazonian rocks in southeastern Laurentia records the northward passage of the Amazon craton along the Laurentian margin, following the original collision with southernmost Laurentia at ca. 1.2 Ga.

Plutonismn in three orogenic pulses, Eastern Blue Ridge Province, southern Appalachians

The Eastern Blue Ridge Province of the southern Appalachians contains, in part, remnants of an Ordovician accretionary wedge complex formed during subduction of an oceanic tract before mid-Ordovician accretion with Laurentia. The Eastern Blue Ridge Province consists of metapelite and amphibolite intruded by low-K plutons, high-temperature (T >750 °C) Ordovician eclogite, and other high-pressure metamafic and meta-ultramafic rocks. Felsic plutons in the Eastern Blue Ridge Province are important time markers for regional-scale tectonics, deformation, and metamorphism. Plutons were thought to be related to either Taconian (Ordovician) or Acadian (Devonian-Silurian) tectonothermal events. We dated five plutonic or metaplutonic rocks to constrain pluton crystallization ages better and thus the timing of tectonism. The Persimmon Creek gneiss yielded a protolith crystallization age of 455.7 ± 2.1 Ma, Chalk Mountain 377.7 ± 2.5 Ma, Mt. Airy 334 ± 3Ma, Stone Mountain 335.6 ± 1.0 Ma, and Rabun 335.1 ± 2.8 Ma. The latter four plutons were thought to be part of the Acadian Spruce Pine Suite, but instead our new ages indicate that Alleghanian (Carboniferous-Permian) plutonism is widespread and voluminous in the Eastern Blue Ridge Province. The Chattahoochee fault, which was considered an Acadian structure, cuts the Rabun pluton and thus must have been active during the Alleghanian orogeny. The new ages indicate that Persimmon Creek crystallized less than 3 m.y. after zircon crystallization in Eastern Blue Ridge eclogite and is nearly synchronous with nearby high-grade metamorphism and migmatization. The three phases of plutonism in the Eastern Blue Ridge Province correspond with established metamorphic ages for each of the three major orogenic pulses along the western flank of the southern Appalachians. © 2006 Geological Society of America.

Additional observations on the gross morphology and microstructure of Baccaconularia Hughes, Gunderson et Weedon, 2000, a Cambrian (Furongian) conulariid from the north-central USA

Baccaconularia Hughes, Gunderson et Weedon, 2000, from the Furongian Series (Cambrian System) of the north-central USA, has been interpreted as a conulariid cnidarian, based on a suite of gross morphological similarities shared only with other post-Cambrian genera currently assigned to this group. Closely spaced, squarish to subrectangular facial nodes of Baccaconularia are aligned in distinct longitudinal files. Nodes also display a subtler, more or less rectilinear transverse alignment, though this pattern commonly is disrupted by offset parallel to the longitudinal files. In their shape and pattern of arrangement, the nodes of Baccaconularia are most similar to the squarish to elongate nodes of Pseudoconularia Bouček, 1939. Longitudinal node files of Baccaconularia may also be compared with the longitudinal facial ridges of Conularia cambria Walcott, 1890 from the Furongian of Wisconsin. Apical angles of Baccaconularia range from approximately 13° to 14.5°. Scanning electron imaging of B. cf. robinsoni shows that its thin, phosphatic skeleton is finely lamellar, with the thickness of individual lamellae measuring approximately 1 μm. The skeleton also exhibits microscopic circular pores and crater-like pits that range from approximately 5 to 10 μm in diameter. These pores and pits are similar in size, geometry, areal density and pattern of arrangement to those of many post-Cambrian conulariids. Microscopic circular pores are documented here for the first time in the genus Archaeoconularia Bouček, 1939 from the Upper Ordovician of the Czech Republic. Although the origin of the pores and pits is open to alternative interpretations, the discovery of these features and fine lamination in Baccaconularia strengthens the argument that this genus is a Cambrian conulariid. © 2006 Nanjing Institute of Geology and Palaeontology, CAS.

Latin America and the Caribbean in the World Economy 2014: Regional integration and value chains in a challenging external environment

The 2014 edition of Latin America and the Caribbean in the World Economy: Regional integration and value chains amid challenging external conditions has four chapters. Chapter I examines the main features of the international context and their repercussions for world and regional trade. Chapter II looks at Latin American and Caribbean participation in global value chains and confirms that the region, with the exception of Mexico and Central America, has only limited linkages with the three major regional value chains of Asia, Europe and North America. This chapter also looks at how participation in value chains may contribute to more inclusive structural change, by analysing three core microeconomic aspects. Chapter III identifies various spheres in which regional integration and cooperation can help strengthen production integration between the economies of Latin America and the Caribbean. The fourth chapter explores the intra- and extraregional trade relations of the countries of the Caribbean Community (CARICOM) and considers how to strengthen production integration in the subregion by taking advantage of linkages beyond trade and building on commercial and production complementarities among the members. The chapter also reviews the differences between the countries in terms of income, population and production and export structure, in a context of marked macroeconomic vulnerability.

Distribuição e conservação de aves migratórias neárticas da ordem Charadriiformes (famílias Charadriidae e Scolopacidae) no Brasil

Apesar dos esforços de pesquisa nos últimos anos, muitos dos aspectos das migrações dos charadrídeos e escolopacídeos no Brasil permanecem desconhecidos. A maioria dos estudos em escala local ou regional revela a necessidade de uma síntese das informações em escala espacial adequada para facilitar a detecção dos grandes padrões de movimento destas espécies no país. Desta forma, esta tese teve como objetivo geral identificar os padrões de distribuição e migrações das espécies de aves das famílias Charadriidae e Scolopacidae que se reproduzem no hemisfério norte e usam o território brasileiro durante as suas migrações, visando desenvolver estratégias para a conservação do grupo. Como objetivos específicos, caracterizar as principais rotas migratórias para estas espécies; identificar as áreas críticas para a conservação utilizando os critérios propostos pela metodologia das AIAs e ACBs; avaliar o estado de conservação atual das áreas críticas para a conservação destas espécies de acordo ao Sistema Nacional de Unidades de Conservação; avaliar se as áreas críticas são parte das áreas prioritárias para a conservação da biodiversidade brasileira; aplicar os critérios da Convenção de Ramsar e da WHSRN para identificar áreas críticas para conservação destas espécies. A base de dados foi estabelecida a partir de levantamento bibliográfico; consultas às coleções científicas de museus brasileiros e estrangeiros; utilização de bases de dados de recuperações de anilhas brasileiras e norte-americanas; dados cedidos por pesquisadores do Brasil, Argentina e Estados Unidos; dados de campo coletados pessoalmente no Pantanal (MS), litoral dos estados do Maranhão e Rio Grande do Sul. Entre os principais resultados, 19 das 24 espécies possuem um conjunto importante de dados, com as demais sendo ocasionais ou com poucas informações. Há uma maior concentração de dados na região costeira do país, com menor cobertura de áreas do interior. A Amazônia Ocidental mostrou-se a menos conhecida nos aspectos abordados, embora seja a via de passagem para algumas das espécies analisadas. O litoral entre a foz do Amazonas e São Luiz, no Maranhão foi a principal área de concentração em termos numéricos. A costa do Rio Grande do Sul foi o segundo local com maior destaque nas análises. Quinze espécies foram registradas em todos os meses do ano, demonstrando que nem todos os indivíduos migram anualmente para o hemisfério norte. Considerando as rotas globais, 8 espécies utilizam a rota do Atlântico e 10 a rota do Mississipi ou do centro da América do Norte. As outras 6 possivelmente utilizam-se das duas rotas. O conhecimento na utilização das 5 rotas propostas por Antas (1983) durante a migração sul-norte indicou que algumas espécies têm registros no interior da Amazônia, período em que possivelmente seus habitats estariam inundados. O padrão de chegada na migração norte-sul no Brasil é entre agosto e outubro, com incremento a partir de setembro. A migração sul-norte ocorre entre meados de março e abril na maioria das espécies. Durante o período não reprodutivo existe um padrão de distribuição ao longo da costa utilizado por 9 espécies, outro continental para 7 espécies no interior e ainda um terceiro, difuso, encontrado em 5 espécies que se distribuem tanto na costa quanto no interior do país. Foram identificadas 260 áreas críticas importantes para as espécies avaliadas. Observou-se que 72% das ACBs identificadas estão fora do SNUC. A sobreposição das ACBs com as Áreas Prioritárias para a Conservação revelou que 46% das primeiras estão sem indicação de importância neste programa. São elegíveis para os critérios da Convenção Ramsar 69 ACBs, enquanto 65 podem ser inseridas no programa da WHSRN. Entre as principais conclusões, o conhecimento de processos biológicos fundamentais à manutenção do ciclo de vida e o curso de suas migrações anuais, de parâmetros relacionados à mudas de penas, ganho de massa corporal, razão sexual e etária das populações migrantes são aspectos ainda insuficientemente detalhados para estas espécies no Brasil, e mesmo na América do Sul, assim como a necessidade de pesquisas que possam gerar estimativas e tendências populacionais, uma vez que em escala global várias destas espécies apresentam declínio populacional.

Book Review of Discovering North American Rock Art Edited by Lawrence L. Loendorf, Christopher Chippindale, and David S. Whitley

If readers of Great Plains Research are seeking a window on rock art research in North America, this book provides a few clear panes, a few that are hazy, and a few muddy ones. Like many edited volumes, the weaker contributions and lack of a consistent style limit the book's usefulness. Some authors target a general readership; others clearly are addressing colleagues. The book has two stated themes: the history of rock art research in North America and recent approaches to rock art analysis. Articles by Julie Francis and (jointly) David Whitley and Jean Clottes explore why rock art research has long been marginalized in North America. Unfortunately, both of these otherwise observant essays slip into advocacy of shamanism as a unifying or primary explanation for rock art, an interpretive model by no means universally accepted by today's rock art specialists.
