Dating WF16: exploring the chronology of a Pre-Pottery Neolithic A settlement in the Southern Levant

A pre-requisite for understanding the transition to the Neolithic in the Levant is the establishment of a robust chronology, most notably for the late Epi-Palaeolithic and Pre-Pottery Neolithic A (PPNA) periods. In this contribution we undertake a dating analysis of the Pre-Pottery Neolithic site of WF16, southern Jordan, drawing on a sample of 46 AMS 14C dates. We utilise Bayesian methods to quantify an old wood effect to provide an offset that we factor into chronological models for a number of individual structures at WF16 and for the settlement as a whole. In doing so we address the influence of slope variations in the calibration curve and expose the significance of sediment and sample redeposition within sites of this nature. We conclude that for the excavated deposits at WF16 human activity is likely to have started by c. 11.84 ka cal bp and lasted for at least c. 1590 years, ceasing by c. 10.24 ka cal bp. This is marked by a particularly intensive period of activity lasting for c. 350 years centred on 11.25 ka cal bp followed by less intensive activity lasting a further c. 880 years. The study reveals the potential of WF16 as a laboratory to explore methodological issues concerning 14C dating of early Neolithic sites in arid, erosional environments.

The Golden Age returns: Virgil's fourth Eclogue in the political panegyric of the Italian courts

E. H. Gombrich and others have analysed the uses made of language and imagery from Virgil's famous fourth Eclogue in panegyrical writing by partisans of the Medici dynasty in Florence. This study examines the appropriation of the theme of the returning Golden Age and related motifs from the fourth Eclogue in other Italian courts during the same period, by supporters of the Visconti and Sforza of Milan, the Gonzaga of Mantua, Leonello d'Este and his successors in Ferrara, and the Bentivoglio of Bologna, among others. The deployment of this Virgilian material in political panegyric is seen to be a central element in the self-definition and self-promotion of dynastic rulers throughout the peninsula.

Variation on the effects of the 2003 CAP reform and regional differences in the Italian olive oil sector

This paper analyses the impacts of the 2003 CAP reform on the production of Italian olive oil controlling for the regional differences in olive oil production as well as for the differences between years. Italian olive oil production time series data from the Farm Accountancy Data Network for the 2000-2010 period at regional level is used to examine the effect of the 2003 Fischler reform on the production of olive oil. Production costs and payments received by farmers to support their income are considered. The data were collected at micro level based on a sample of farms representative of the production systems in the country. In order to consider the differences in production among the regions, eight representative regions in terms of surveyed farms are considered: Liguria, Toscana, Umbria, Lazio, Campania, Calabria, Puglia and Sicilia. We found that the most important factors affecting the production of olive oil are the area under olive groves and labour productivity. Results also show no evidence that the level of payments have an impact to the level of production, however, the type of payments has. Future work should explore the impact of the 2003 reform into the technical and production efficiency of the Italian olive oil farmers. It would be interesting to link the measures introduced by the cross compliance and the management practices of the different farms to have a more complete picture of the various parameters influencing the production of olive oil.

The rise and fall of Benedetto Croce: intellectual positionings in the Italian cultural field 1944-1947

This article evaluates the discourse developed around Benedetto Croce in the Italian cultural periodical press between 1944 and 1947 and it discusses the forms of adversarial discourse and the agents involved in the anti-Croce polemics that unfolded in the Communist party’s official cultural journal Rinascita. Specifically, this article focuses on a selection of intellectuals who moved away from Crocean idealism to embrace Marxism in order to investigate how their conversion was presented in Rinascita.

Chemical process to separate iron oxides particles in pottery sample for EPR dating

Ancient potteries usually are made of the local clay material, which contains relatively high concentration of iron. The powdered samples are usually quite black, due to magnetite, and, although they can be used for thermoluminescene (TL) dating, it is easiest to obtain better TL reading when clearest natural or pre-treated sample is used. For electron paramagnetic resonance (EPR) measurements, the huge signal due to iron spin-spin interaction, promotes an intense interference overlapping any other signal in this range. Sample dating is obtained by dividing the radiation dose, determined by the concentration of paramagnetic species generated by irradiation, by the natural dose so as a consequence, EPR dating cannot be used, since iron signal do not depend on radiation dose. In some cases, the density separation method using hydrated solution of sodium polytungstate [Na(G)(H(2)W(12)O(40))center dot H(2)O] becomes useful. However, the sodium polytungstate is very expensive in Brazil: hence an alternative method for eliminating this interference is proposed. A chemical process to eliminate about 90% of magnetite was developed. A sample of powdered ancient pottery was treated in a mixture (3:1:1) of HCI, HNO(3) and H(2)O(2) for 4 h. After that, it was washed several times in distilled water to remove all acid matrixes. The original black sample becomes somewhat clearer. The resulting material was analyzed by plasma mass spectrometry (ICP-MS), with the result that the iron content is reduced by a factor of about 9. In EPR measurements a non-treated natural ceramic sample shows a broad spin-spin interaction signal, the chemically treated sample presents a narrow signal in g= 2.00 region, possibly due to a radical of (SiO(3))(3-), mixed with signal of remaining iron [M. lkeya, New Applications of Electron Spin Resonance, World Scientific, Singapore, 1993, p. 285]. This signal increases in intensity under -gamma-irradiation. However, still due to iron influence, the additive method yielded too old age-value. Since annealing at 300 degrees C, Toyoda and Ikeya IS. Toyoda, M. Ikeya, Geochem. J. 25 (1991) 427-445] states that E `(1)-signal with maximum intensity is obtained, while annealing at 400 degrees C E`(1)-signal is completely eliminated, the subtraction of the second one from 300 degrees C heat-treated sample isolate E`(1)-like signal. Since this is radiation dose-dependent, we show that now EPR dating becomes possible. (C) 2008 Elsevier B.V. All rights reserved.

SEM, EPR and ToF-SIMS analyses applied to unravel the technology employed for pottery-making by pre-colonial Indian tribes from Pantanal, Brazil

The present work aims at elucidating the technology applied in the fabrication of ceramic objects by the ancient ceramists that inhabited the western border of Pantanal, Mato-Grosso do Sul, with the help of a multidisciplinary approach making use of chemical and physical methods of analysis. The potshards under study show the presence of different types of additives, as determined by scanning electron microscopy (SEM) and time of flight secondary ion mass spectrometry (ToF-SIMS). The dispersion of the additives within the ceramic matrix was also addressed by SEM, which shed light on the mounting technique used by the potters to assemble the ceramic vessels. Moreover, the tensile strength conferred to the pottery by the use of a specific type of additive was evaluated by applying a mechanical test. These results were correlated with the firing temperature of the potshards, determined by means of electron paramagnetic resonance (EPR). (C) 2010 Elsevier Ltd. All rights reserved.

The Björling 'Opera' : A children's Nursery Academy and an Italian Conservatory in Miniature

The aim in this chapter is to develop a deeper understanding about the informal Björling 'School' in Sweden. Contextually the example is related to the micro history of opera education contributing to the macro perspective illuminating a provincial example of the concept of domestic opera schooling. The specific focus was on Karl David Björling (1873-1926), the teaching parent of the Swedish tenor Jussi Björling (1911-1960) and his brothers Gösta and Olle.   The Björling family model of opera schooling belongs to the classical canon of domestic home education which was common during the epoch. The phenomenon is also within the field of opera singing an important reference to the historical context of the Nordic opera history of vocal education.   The uniqueness concerning the Björling School seems to be the rigorous and exceptionally early training. David Björling’s pedagogy was rooted in earlier German theories of musical upbringing. It's clear from his results that he was familiar with the neo-humanistic ideal on which reformed music education was based. Of a specific interest is the term Gesang als Unterricht as a concept for developing childrens musical and memorising capacities.   Conceptually the roots of the Björling model are in the eighteenth-century Romantic view of prodigies and their abilities. The extensive touring is connected to the promotion of wonder-children, and David Björling’s educational style to the conservative Master-pupil tradition.   David Björling's vocal ideal was a part of the contemporary debate about “The decadence of the singing art”, and seems to have its roots in an older Italian tradition. There are recurring similarities between his educational methods and the didactic principles of the Lamperti School: Enjoying a revival around the late 1800s and early 1900s, it has been called the natural or the national school. Nevertheless, through authentic experiences and gramophone recordings the Italian tenor Enrico Caruso became David Björling’s pedagogical role model.

The country of origin effect: tracking Brazil’s brand image among italian consumers

O Brasil se tornou nos últimos anos uma importante economia no cenário global. O país sempre foi visto basicamente como um exportador de commodities; no entanto, devido ao crescimento de investimentos e ao desenvolvimento de diversos setores econômicos, essa imagem mudou e está em processo de reconstrução. As empresas para poderem se diferenciarem e ganharem competitividade, precisam entender profundamente como consumidores percebem e avaliam os produtos brasileiros atualmente. É de extrema importância para o Brasil entender o potencial competitivo para posicionar-se corretamente contra as nações desenvolvidas e altamente industrializadas, bem como contra as gigantes economias emergentes como Rússia, China e Índia. Este estudo explora como um grupo de respondentes italianos avaliam a categoria de cosméticos brasileiros. Foi conduzida uma pesquisa exploratória com o objetivo de identificar dentre quarto categorias diferentes de produtos qual seria analisada em detalhe posteriormente por meio de entrevistas em profundidade. Das 4 categorias diferentes de produtos (vestuário, cosméticos, frutas frescas e carnes) foi selecionada a categoria cosméticos que obteve a menor avaliação geral no estudo exploratório. Após a escolha da categoria a ser analisada, uma pesquisa qualitativa com 7 entrevistas em profundidade com consumidores italianos residentes no Brasil foram realizadas. Das pesquisas realizadas são obtidas as percepções de um grupo de consumidores sobre os atributos e associações psicológicas sobre a categoria de cosméticos brasileiros. A análise será conduzida utilizando 3 componentes para explicar a atitude de consumo: a cognitiva, a conativa e a emocional. Deste modo, os resultados e conclusões são apresentados e explorados. Ademais, um mapa psicológico das atitudes sobre a categoria analisada perante o público estudado será desenvolvido, com o objetivo de pontuar suas forças e fraquezas. Desta análise final será possível ter uma visão ampla das características, bem como dos pontos críticos que precisam ser melhorados no futuro para que o Brasil seja uma nação competitiva na indústria de cosméticos e também algumas questões que podem ser estendidas a outros setores da economia brasileira.

A comparative study of internationalization potential for Italian SMEs in the fashion industry in Brazil and Russia

Este estudo tem como objetivo desenvolver uma análise comparativa do potencial de internacionalização na Rússia e no Brasil para as PME italianas que operam na indústria da moda. Depois de apresentar ao leitor as principais áreas cobertas, tais como, o contexto, a metodologia e revisão da literatura, é fornecido um panorama macroeconômico das áreas geográficas composto, englobando um estudo específico sobre o estado atual da economia e da demanda para os bens italianos. O estudo, introduzindo o leitor na indústria de moda italiana, suas principais características e o desempenho atual, já evidencia a busca pela internacionalização. As conclusões decorrentes das análises macroeconômicas funcionam como introdução à visão geral da indústria de moda italiana, uma indústria que representa, fortemente, o "Made in Italy" no exterior. A breve análise da história desta indústria, principais características e situação atual irão, então, sugerir que a internacionalização é o caminho mais viável às PME, para se recuperarem dos anos turbulentos da crise. Entre o vasto conjunto de opções geográficas que as PME têm para abraçar internacionalização, este estudo tem como objetivo fornecer duas análises sobre a indústria da moda: o mercado russo e o brasileiro. A análise, com base no quadro de capacidade de ‘resposta internacional’ proposto por Bartlet e Ghoshal (1989), apresenta os resultados de um conjunto de pesquisas e entrevistas realizadas no Brasil, na Itália e na Rússia, sob a forma de uma análise comparativa dos dois mercados-alvo. A análise evidenciará os drivers de mercado, custo, competitividade e legislação que justificam o processo de internacionalização em ambos os mercados. Os resultados levam à conclusão e às recomendações que os dois mercados representam duas oportunidades muito diferentes para as PME da indústria da moda italiana.

Cultures at work: the case of italian expatriates in Brazil

Esta tese de mestrado tem por intenção entender quais são as mais importantes diferenças culturais para os expatriados Italianos que trabalham no Brasil e aprender as implicações práticas para o ambiente de trabalho. O método utilizado foi qualitativo, com 23 entrevistas em profundidade com expatriados italianos de nível médio ate top management, com experiência de trabalho no Brasil. Os resultados indicam que os expatriados Italianos experimentam dificuldades com as diferenças em termos de comunicação, distinção entre as esfera profissional e privada, distancia do poder e planejamento. Em contrapartida, outros fatores como a discriminação positiva para os estrangeiros, diferenças em geneder equality e masculinidade, assim como com a atitude positiva dos workplaces e uma economia em crescimento, todos influenciam de maneira positiva a experiência do expatriado. Enfim, algumas sugestões práticas sobre os efeitos das diferenças culturais e sobre a estruturação de um possível cross-cultural training são expostas.

Economic traits and performance of Italian quails reared at different cage stocking densities

This study assessed the effect of different cage stocking densities on the performance of Italian quails in the laying period. Two hundred and sixty four quails with 30 weeks of age and 280g mean body weight were used. Birds were randomly assigned to 96 x 33 x 16 cm cages and distributed in a randomized block design with 4 treatments (12, 15, 18 and 21 quails per cage or 264, 211, 176 and 151 cm² per quail, respectively) and 4 replicates. Birds were given feed and water ad libitum and submitted to the same experimental conditions. The experimental diet was formulated based on NRC (1994) recommendations. There were no significant differences among treatments for feed conversion per egg mass (kg:kg), percentage of broken eggs and mortality. There was a linear reduction (p<0.05) in egg weight, feed consumption, percentage of production, egg mass and feed conversion per dozen with the increase in stocking density. The gain per house per day was better at the cage density of 151 cm² per bird. However, the density of 211 cm² per bird provided the best gain per bird per day, because this stocking density had better productive indexes when compared with the other treatments.
