Writing and living on the stage of history

This article studies the intercultural trajectory of a Portuguese female aristocrat of the eighteenth to nineteenth centuries. Her trajectory of intercultural transition from a Portuguese provincial lady into an independent owner of a sugar mill in tropical Bahia is documented through family letters, which provide a polyphonic representation of a movement of personal, family, and social transculturation over almost two decades. Maria Bárbara began her journey between cultures as a simple spectator-reader, progressively becoming a commentator-actor-protagonist-author in society, in politics, and in history. These letters function as a translation that is sometimes consecutive, other times simultaneous, of the events lived and witnessed. This concept of intercultural translation is based on the theories of Boaventura de Sousa Santos (2006, 2008), who argues that cultural differences imply that any comparison has to be made using procedures of proportion and correspondence which, taken as a whole, constitute the work of translation itself. These procedures construct approximations of the known to the unknown, of the strange to the familiar, of the ‘other’ to the ‘self’, categories which are always unstable. Likewise, this essay explores the unstable contexts of its object of study, with the purpose of understanding different rationalities and worldviews.

Reconstruction of geomagnetic activity and near-Earth interplanetary conditions over the past 167 yr - Part 3: improved representation of solar cycle 11

Svalgaard (2014) has recently pointed out that the calibration of the Helsinki magnetic observatory’s H component variometer was probably in error in published data for the years 1866–1874.5 and that this makes the interdiurnal variation index based on daily means, IDV(1d), (Lockwood et al., 2013a), and the interplanetary magnetic field strength derived from it (Lockwood et al., 2013b), too low around the peak of solar cycle 11. We use data from the modern Nurmijarvi station, relatively close to the site of the original Helsinki Observatory, to confirm a 30% underestimation in this interval and hence our results are fully consistent with the correction derived by Svalgaard. We show that the best method for recalibration uses the Helsinki Ak(H) and aa indices and is accurate to ±10 %. This makes it preferable to recalibration using either the sunspot number or the diurnal range of geomagnetic activity which we find to be accurate to ±20 %. In the case of Helsinki data during cycle 11, the two recalibration methods produce very similar corrections which are here confirmed using newly digitised data from the nearby St Petersburg observatory and also using declination data from Helsinki. However, we show that the IDV index is, compared to later years, too similar to sunspot number before 1872, revealing independence of the two data series has been lost; either because the geomagnetic data used to compile IDV has been corrected using sunspot numbers, or vice versa, or both. We present corrected data sequences for both the IDV(1d) index and the reconstructed IMF (interplanetary magnetic field).We also analyse the relationship between the derived near-Earth IMF and the sunspot number and point out the relevance of the prior history of solar activity, in addition to the contemporaneous value, to estimating any “floor” value of the near-Earth interplanetary field.

A pictorial representation of peristomal architecture

The terminology associated with the use of peristomes in the identification and classification of mosses is cumbersome and difficult to understand. This paper provides a pictorial explanation of peristomal architecture with its associated terminology, such as nematodontous and arthrodontous peristomes, and the division of the latter into diplolepideous and haplolepideous peristomes.

Trauma and holocaust video testimony : the intersection of history, memory, and judgment in the interview process

This article analyzes video testimonies recorded at the Jewish Holocaust Museum and Research Centre in Melbourne,Australia, which address the highly complex and sensitive issue of “privileged” Jews. The so-called privileged Jews include prisoners in the Nazi-operated camps and ghettos who held positions that gave them access to material and other benefits, while compelling them to act in ways that have been judged detrimental to fellow inmates. Although the issue of “privileged” Jews has been largely neglected, it relates to a crucial facet of the Holocaust and has vast implications for its aftermath. The ethical dilemmas facing these victims may be closely linked to what Lawrence Langer has termed choiceless choices, which challenge conventional notions of “judgment” and “responsibility.” This problem is also the primary subject of Auschwitz survivor Primo Levi’s essay titled “The Grey Zone,” which is arguably the most influential essay ever written on the Holocaust. Levi argues that one should abstain from judging individuals who confronted such extreme circumstances, positioning prisoners with “privileged” positions at the threshold of representation and understanding. However, moral evaluations of “privileged” Jews have a strong impact on Holocaust testimonies, whether these were constructed during the war or recorded long after the survivors’ experiences. The examples of video testimonies explored in this article reveal that this is particularly the case when interviewees are former “privileged” Jews and interviewers are themselves Holocaust survivors. The article argues that when confronted with such an emotionally and morally fraught issue, judgment may itself be seen as a “limit of representation.”

A method for the visual representation of historic multivariate point data

The visual representation of multivariate spatial and temporal data is important for interpreting and analyzing historical geographic patterns that change over time. The introduction of geospatial technologies in historical scholarship has challenged the suitability of current visual representations due to the need for greater temporal emphasis and the tracking of historical events over time. This research presents a holistic multivariate approach to historical visual representation for point based historical data. The method has been developed through extending the spatial presence in information graphics and through meaningful spatial classification. This paper demonstrates the benefits gained from integrating historical, geographic, temporal, and attribute data through the development of a case study on the history of Melbourne’s cinema venues between 1946 and 1986.

Representation of multiculturalism in urban green spaces : a review of immigrants' experiences in Australia

Rapid population influx due to migration in Australia has produced diverse cultural landscapes, which become visible in cities as physical forms, settings and symbols produced by different ethnic communities. Scholars have argued that people moving away from the country of their birth, whether this be a necessary migration, labour mobility or voluntary migration, results in a difficult process of resettlement for families and individuals. To provide a cohesive multicultural society for all citizens, it is essential to understand how immigrants perceive their new environments and how they make connections in a new land in the process of cultural renewal. While the policy of ‘multiculturalism’ has had a rocky road since the optimistic 1970s, a drive through many suburbs in Australian cities shows buildings, festivals and communal gatherings of people that express and refer to diverse cultural backgrounds. Urban green spaces, ranging from private home gardens to public parks and botanical gardens, play an important role in the life of immigrants. Besides psychological and the restorative effects of urban green spaces, these spaces are public places that provide opportunities for recreation, social gatherings, and the celebration of collective cultural values and events such as festivals for many communities. This study aims to raise awareness of ethnicity as an important issue in park settings and spaces. It investigates the interrelationship between these cultural practices in the urban park environment, in relation to ethnic and cultural identity and physical settings. The concept of transculturalism – reinventing a new common culture as a result of migration to a new place – can help the analysis of the affects and the perception of urban green spaces. The paper will review different experiences of immigrants in relation to the use and perception of urban green spaces, developing alternative perspectives about the Australian landscapes.

Evolution of representation of the hands in plastic arts

A interação entre arte e ciência foi intensa durante o Renascimento, sofrendo declínio nos anos posteriores com retomada significativa no século XX, principalmente com o uso de técnicas de identificação, datação de obras de arte e o desenvolvimento de novos materiais. O relacionamento entre artes plásticas e Cirurgia da Mão mantêm-se intenso , sendo freqüente o uso de reproduções artísticas da mão nas ilustrações de textos científicos. Objetivando compreender o papel da mão nas artes plásticas, reproduções de obras de artes (esculturas e pinturas) representativas de vários estilos ou períodos da história da arte foram analisadas com enfoque no estudo das mãos. Detalhes anatômicos, relacionamento com outras estruturas do corpo humano, papel na composição e aspectos simbólicos das mãos foram estudados no contexto histórico e artístico de obras de arte do período paleolítico (pré-história) até o século XX. A representação da mão nas artes plásticas está diretamente relacionada ao estilo ou período da obra e à capacidade individual de interpretação e execução do artista.

Comparative genomic hybridization analysis detects frequent over-representation of DNA sequences at 3q, 7p, and 8q in head and neck carcinomas

Comparative genomic hybridization (CGH) was used to identify chromosomal imbalances in 19 samples of squamous cell carcinoma of the head and neck (HNSCC). The chromosome arms most often or er-represented were 3q (48%), 8q (42%), and 7p (32%); in many cases, these changes were observed at high copy number. Other commonly over-represented sites were 1q, 2q, 6p, 6q, and 18q. The most frequently under-represented segments were 3p and 22q. Loss of heterozygosity of two polymorphic microsatellite loci from chromosome 22 was observed in two tongue tumors, in agreement with the CGH analysis. Gains of 1q and 2q material were detected in patients exhibiting a clinical history of recurrence and/or metastasis followed by terminal disease. This association suggests that gain of 1q and 2q map be a new marker of head and neck tumors with a refractory clinical response. (C) 2000 Elsevier B.V. All rights reserved.

An anisotropic viscous representation of Mohr-Coulomb failure for use is modelling coupled mantle-continent dynamics

In mantle convection models it has become common to make use of a modified (pressure sensitive, Boussinesq) von Mises yield criterion to limit the maximum stress the lithosphere can support. This approach allows the viscous, cool thermal boundary layer to deform in a relatively plate-like mode even in a fully Eulerian representation. In large-scale models with embedded continental crust where the mobile boundary layer represents the oceanic lithosphere, the von Mises yield criterion for the oceans ensures that the continents experience a realistic broad-scale stress regime. In detailed models of crustal deformation it is, however, more appropriate to choose a Mohr-Coulomb yield criterion based upon the idea that frictional slip occurs on whichever one of many randomly oriented planes happens to be favorably oriented with respect to the stress field. As coupled crust/mantle models become more sophisticated it is important to be able to use whichever failure model is appropriate to a given part of the system. We have therefore developed a way to represent Mohr-Coulomb failure within a code which is suited to mantle convection problems coupled to large-scale crustal deformation. Our approach uses an orthotropic viscous rheology (a different viscosity for pure shear to that for simple shear) to define a prefered plane for slip to occur given the local stress field. The simple-shear viscosity and the deformation can then be iterated to ensure that the yield criterion is always satisfied. We again assume the Boussinesq approximation - neglecting any effect of dilatancy on the stress field. An additional criterion is required to ensure that deformation occurs along the plane aligned with maximum shear strain-rate rather than the perpendicular plane which is formally equivalent in any symmetric formulation. It is also important to allow strain-weakening of the material. The material should remember both the accumulated failure history and the direction of failure. We have included this capacity in a Lagrangian-Integration-point finite element code and will show a number of examples of extension and compression of a crustal block with a Mohr-Coulomb failure criterion, and comparisons between mantle convection models using the von Mises versus the Mohr-Coulomb yield criteria. The formulation itself is general and applies to 2D and 3D problems, although it is somewhat more complicated to identify the slip plane in 3D.

Uses of history in history education

This compilation thesis contains an introductory chapter and four original articles. The studies comprising this thesis all concern aspects of how historical culture is constituted in historical media and history teachers’ narratives and teaching. It is argued that the teaching of history is a complex matter due to an internal tension resulting from the fact that history is both a product and a process at the same time. While historical facts, and knowledge thereof, are an important aspect of history, history is also a product of careful interpretation and reconstruction. This study analyses and discusses how history is constituted in history textbooks and popular history magazines, i.e. two common historical media, and in teachers’ narratives and teaching of history. The study finds that the historical media studied generally tend to present history as void of perspective, interpretation and representation, suggesting this to be the culturally warranted form of historical exposition. Moreover, the teachers studied also tend to approach history as if it were not contingent on interpretation and reconstruction. These results indicate that the history disseminated in historical media and history classrooms presents history in a factual way and disregards the procedural aspects of history. Applying the history didactical concepts of historical consciousness, historical culture and uses of history, this thesis argues that an essential aspect of historical understanding is an appreciation of the contextual contingency that characterises history. All history is conceived within a particular context that is pertinent to why and how a certain version of history is constructed. Furthermore, all history is also received within a particular context by people with particular preconceptions of history that are contextually contingent, in the sense that they are situated in a certain historical culture. Readers of historical media are members of societies and are thus affected by how history is perceived and discussed in these contexts. This thesis argues that an awareness of these aspects of history is an important factor for furthering a complex understanding of history that encompasses the tension highlighted above.

A Critique of the Representation of Violence in American Literature:

The purpose of this thesis was to draw new insights on Thomas Berger’s classic American novel, Little Big Man, and his representation of fictional violence that is a substantial aspect of any text on the Indian Wars and “Custer’s Last Stand”. History’s major world wars led to shifts in the political climate and a noted change in the way that violence was represented in the arts. Historical, fictional, and cinematic treatments of “Custer’s Last Stand” and violence were each considered in relation to the text. Berger's version of the famed story is a revision of history that shows the protagonist as a dual-member of two violent societies. The thesis concluded that Berger’s updated American legends and unique “white renegade” character led to a representation of violence that spoke to the current state of affairs in 1964 when the world was becoming much more hostile and chaotic place.
