No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Sócio-Econômico. Programa de Pós-Graduação em Economia.Com o presente trabalho objetiva-se estudar as condições competitivas da indústria de papel de embalagem do estado de Santa Catarina e propor políticas públicas e estratégias empresariais, no intuito de contribuir para estudos que buscam caracterizar esta estrutura industrial catarinense. A indústria de papel de embalagem possui algumas características, entre elas o alto grau de concentração produtiva; presença de fortes barreiras de entrada; grau elevado de verticalização; a indústria é tecnologicamente madura; grande incidência de reparos incrementais nas máquinas e equipamentos (up grades), entre outras. Para se proceder a análise das condições competitivas desta indústria dentre os diversos modelos teóricos possíveis, optou-se pelo Estudo da Competitividade da Indústria Brasileira - ECIB, de Coutinho e Ferraz (1994) e Ferraz et alii (1997), por tratar-se do mais adequado para esta análise específica. Assim, a partir da construção de uma discussão teórica acerca do padrão de concorrência, da estrutura de mercado, dos modelos teóricos de análise da competitividade, buscou-se caracterizar, por meio de pesquisa em fontes secundárias e dados, a indústria de papel de embalagem em níveis mundial, brasileiro e catarinense, tomando-se por base os resultados da pesquisa de campo, pôde-se traçar as condições competitivas da indústria de papel de embalagem do estado de Santa Catarina, partindo-se para uma comparação da estrutura industrial catarinense em relação ao padrão mundial estabelecido nesta indústria. Finalmente, traçou-se políticas públicas e estratégias empresariais para esta indústria, baseando-se nos pontos positivos e negativos detectados neste segmento da indústria e conclui-se o trabalho

Bridging the 'gap‘ between migrants and the banking system: an innovative business model promoting financial integration, financial stability, and profitability
No full textThe thesis probes a specific area - the banking system and the business niche concerned with migrants' remittances - and considers the flows of these people and their money in today‘s global economy (over 3% of the world's population). It argues that the banking system has failed to understand the changing "paradigm" of the migrant market and thus has not updated its business plan or business model for this business segment in response. In failing to harness the liquidity of the migrant market, the author argues, the banking industry is missing out on a potentially profitable business segment that could create financial stability within the industry and the world's economies. Furthermore, by ignoring the "gap" that exists between the financial products on offer to the migrant sector and their needs in this respect in both the host and origin countries - providing a service at "both ends of the corridor" - the industry is also in danger of losing site of its commitment to social responsibility and the financial integration of migrants. At the heart of the argument for financial stability and financial integration is the proposition that there is a lack of communication among stakeholders, namely academic and financial institutions, governments, Diaspora associations and other decision makers
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Portulaca ferricola J. R. Ferraz & Hassemer
No full textPortulaca ferricola J.R.Ferraz & Hassemer, nom. et stat. nov. ≡ Portulaca mucronulata var. microphylla Legrand (1949: 355) non Richard (1845: 620) (Art. 6.11 of the ICN). Type: — BRAZIL. Mato Grosso do Sul: Corumbá, March 1906, Etchichury 85 (holotype SI 003157!). Diagnosis:— Portulaca ferricola can be morphologically distinguished from the other Portulaca species by the combination of the following characters:slightly swollen roots,decumbent branches and stem covered with an exfoliating bark, lanceolate or ovate-lanceolate leaves, abundant leaf axillary hairs stiff and a hemispheric operculum. Description (Figs. 1, 2, and 4): — Perennial succulent herb, up to 6 cm high; roots slightly swollen, covered with an exfoliating brown bark. Stem branched, covered with an exfoliating brown bark; primary branches 4‒12 cm long, decumbent, covered with an exfoliating bark, green in young living specimens, brownish in old living specimens, pale yellow or brownish in herbarium material; secondary branches usually with internodes very short, which gives the branch the appearance of a fascicle. Leaves alternate, subopposite at the apex, simple, fleshy, green in a wet environment, reddish in a dry environment; petiole 0.4‒0.6 mm long, green lighter than the blade; blades 3.5‒8.5 × 1.0‒ 2.5 mm, terete, lanceolate or ovate-lanceolate, adaxially and abaxially glabrous; base slightly rounded; apex acute, reddish; margins entire; leaf axillary hairs abundant (denser at the apex), up to 2 cm long, stiff, white in living specimens, yellow or brownish in herbarium material. Inflorescence a terminal head, 2‒4-flowered, subtended by an involucre of 6‒15 leaves. Flowers sessile; sepals 2, unequal, connate at the base, 5.2‒7.8 × 4.0‒ 6.5 mm, ovate, apex acuminate, margins scarious; petals 5, magenta, sometimes vinaceous, with a reddish spot in the adaxial surface at the base, 1.5‒2.2 × 0.8‒1.6 cm, obovate, apex obcordate, emarginate; stamens 50‒80, filaments connate at the base and forming a ring ca. 0.8‒1 mm long, filaments 2.0‒4.5(‒5.0) mm long, unequal, magenta, glabrous; anthers ca. 1 mm long, dark yellow, pollen released through longitudinal slits; ovary sub-globose; style 7.5‒8 mm long, very thickened near the stigmatic branches, magenta, glabrous; stigma magenta, 5‒10-lobed, 1.5‒2.2 mm long, linear, 3-nerved, the stigmatic surfaces covered with small hairs. Fruit a circumscissile capsule, sessile or pedicelate, pedicel 0.2‒0.4 mm long, capsule 4.0‒ 6.5 mm long, dehiscence line ca. at the lower third; operculum hemispheric, green, shiny, apiculate; fruit base sometimes reduced. Seeds ca. 30 per capsule, 0.52‒0.85 mm, subreniform, black, ornate, constriction zone present, individual cells elongated, anticlinal walls undulate with T-, U-, and V-type patterns, sometimes bifurcating, periclinal walls convex, the cells toward the peripheral face of the seed par-domed. Etymology:— The specific epithet “ ferricola ” is derived from the Latin ferreus (iron) and - icola (dweller), referring to the ironstone outcrops and shallow ferruginous soils, habitats in which the species is found. Phenology:— Flowering and fruiting times from December to June. Geographic distribution and habitat:— Portulaca ferricola was collected in two municipalities (Corumbá and Ladário) in western Mato Grosso do Sul State, Brazil, and in one province (Germán Busch) in Santa Cruz Department, eastern Bolivia (Fig. 3). This species is endemic to ironstone grasslands (canga vegetation), growing in ironstone outcrops and shallow soils at an elevation of 100–280 m a.s.l. This canga vegetation is surrounding by savannas and Seasonal Decidual Forest and occur along the foot of the plateau hills, presenting an impermeable substrate and with little presence of sediments (Takahasi & Meirelles 2014, Villarroel et al. 2017). The associated plants includes edaphic endemic species, such as Gomphrena centrota Holzhammer (1955: 188), Discocactus ferricola Buining & Brederoo (1975: 2), and Deuterocohnia meziana Kuntze ex Mez (1896: 465) (Lima et al. 2019). Conservation status:— Endangered (EN – B1ab[i, ii, iii]+2ab[i, ii, iii]). There are only five known populations of Portulaca ferricola occupying an AOO (Area of Occupancy) of 20 km 2 and EOO (Extent of Occurrence) of 294.066 km 2. The major threats to this species include habitat degradation, trampling from cattle and direct competition by invasive non-native plant species from adjacent pastures, such as the grass Megathyrsus maximus (Jacquin 1781: 2) Simon & Jacobs (2003: 572). Nomenclatural notes:— Elevation of Portulaca mucronulata var. microphylla to species rank was not possible by means of a new combination, because of the existence of the earlier and validly published name P. microphylla Richard (1845: 620). Therefore, P. ferricola, a new name, is proposed, in accordance with Art. 6.11 of the ICN. Taxonomic notes:— The abundant stiff leaf axillary hairs are an unusual feature in Portulaca species that give herbarium specimens a caterpillar-like appearance (Legrand 1962). In addition to P. ferricola, only three other South American species have very conspicuous stiff trichomes: P. cardenasiana, P. eruca, and P. mucronulata var. mucronulata. Portulaca cardenasiana (dry Chaco vegetation from Bolivia and Paraguay) shares with P. ferricola the ovatelanceolate leaves and branches and roots with exfoliating bark. However, P. ferricola can be distinguished from P. cardenasiana by the smaller branches (4‒12 cm vs. 15‒20 cm), stem habit (decumbent vs. decumbent to erect), apices of branches not widened and with a series of 6‒15 leaves (vs. widened and with more than 20 leaves organized in several series), and operculum shape (hemispheric vs. campanulate to subconical) (Table 1). Furthermore, P. cardenasiana can be easily recognized in herbaria by its short fascicles of leaves overlapped by brown trichomes, which persist after the leaf-fall (Fig. 5). Portulaca ferricola also has reproductive characters similar to P. eruca (endemic species from Argentina and Paraguay; Fig. 6) and P. mucronulata var. mucronulata (mountain range in central Argentina; Fig. 7). P. ferricola differs from P. eruca by the stem ramification and habit (branched and decumbent vs. simple to few branched and decumbent to erect), roots (slightly swollen vs. tuberous), and leaf shape (lanceolate or ovate-lanceolate vs. subulate) (Table 1). On the other hand, P. ferricola can be distinguished from P. mucronulata var. mucronulata by the leaf shape (lanceolate or ovate-lanceolate vs. linear), longer petals (1.5‒2.2 cm vs. 0.8‒1.0 cm), and the presence of an exfoliating bark in the branches, stem and roots (vs. absent) (Table 1).
