Singing Through Struggle: Music as a Mode of Cultural Exchange in African American Border City Churches After Emancipation, 1862-1890

This project investigates how religious music, invested with symbolic and cultural meaning, provided African Americans in border city churches with a way to negotiate conflict, assert individual values, and establish a collective identity in the post- emancipation era. In order to focus on the encounter between former slaves and free Blacks, the dissertation examines black churches that received large numbers of southern migrants during and after the Civil War. Primarily a work of history, the study also employs insights and conceptual frameworks from other disciplines including anthropology and ritual studies, African American studies, aesthetic theory, and musicology. It is a work of historical reconstruction in the tradition of scholarship that some have called "lived religion." Chapter 1 introduces the dissertation topic and explains how it contributes to scholarship. Chapter 2 examines social and religious conditions African Americans faced in Baltimore, MD, Philadelphia, PA, and Washington, DC to show why the Black Church played a key role in African Americans' adjustment to post-emancipation life. Chapter 3 compares religious slave music and free black church music to identify differences and continuities between them, as well as their functions in religious settings. Chapters 4, 5, and 6 present case studies on Bethel African Methodist Episcopal Church (Baltimore), Zoar Methodist Episcopal Church (Philadelphia), and St. Luke’s Protestant Episcopal Church (Washington, DC), respectively. Informed by fresh archival materials, the dissertation shows how each congregation used its musical life to uphold values like education and community, to come to terms with a shared experience, and to confront or avert authority when cultural priorities were threatened. By arguing over musical choices or performance practices, or agreeing on mutually appealing musical forms like the gospel songs of the Sunday school movement, African Americans forged lively faith communities and distinctive cultures in otherwise adverse environments. The study concludes that religious music was a crucial form of African American discourse and expression in the post-emancipation era. In the Black Church, it nurtured an atmosphere of exchange, gave structure and voice to conflict, helped create a public sphere, and upheld the values of black people.

Press, politic, and social order in Buenos Aires during the 1850s

The paper examines some reflections and discussions about the role and nature of the press that took place in Buenos Aires during the 1850s, referring to the difficulties involved in congenial freedom and order. This was caused by the fact that the press was considered a pillar of republican and civilized societies, but also an agent capable of corroding the social and political order.

Comparison of genetic and morphological methods to detect the presence of American lobsters, Homarus americanus H. Milne Edwards, 1837 (Astacidea: Nephropidae) in Norwegian waters

American lobsters (Homarus americanus H. Milne Edwards, 1837) are imported live to Europe and should according regulations be kept in land-based tanks until sold. In spite of the strict regulations aimed specifically at preventing the introduction of this species into the NE Atlantic, several specimens of H. americanus have been captured in the wild, especially in Oslofjord, Norway since 1999. One of the great concerns is interbreeding between the introduced American species and the local European lobster, H. gammarus (Linnaeus, 1758). For this reason an awareness campaign was launched in 2000 focusing on morphologically "unusual" lobsters caught in local waters. Morphological characters have been based on colour and sub-ventral spines on the rostrum. Two samples of H. americanus were used for comparisons, as well as samples of European lobster from Oslofjord collected in 1992. Previous genetic analyses (allozymes, mtDNA and microsatellite DNA) have demonstrated that the American lobster is distinct from its European counterpart, with several additional alleles at many loci in addition to different allelic frequency distribution of alleles of "shared" alleles. During the present study, thirteen microsatellite loci were tested in the initial screening, and the three most discriminating loci (Hgam98, Hgam197b and Hgam47b) were used in a detailed comparison between the two species. A total of 45 unusual lobsters were reported captured from Ålesund (west) to Oslofjord (southeast) from 2001 to 2005 and these were analysed for the three microsatellite loci. Nine specimens were identified as American lobsters. Comparisons between morphological and genetic characteristics revealed that morphological differences are not reliable in discrimination the two species, or to identify hybrids. Further, some loci display almost no overlapping in allele frequency distribution for the reference samples analysed, thus providing a reliable tool to identify hybrids.

First record of minimum Irish hare (Lepus timidus hibernicus Bell 1837) longevity in the wild.

Average longevity of the mountain hare (Lepus timidus L., 1758) has been estimated at nine years in the wild (Macdonald D. and Barrett, P. 1993 Mammals of Britain and Europe. Harper Collins Publishers, London) with a maximum recorded age of 18 years for one marked animal (Angerbjörn, A. and Flux, J. E. C. 1995 Lepus timidus. Mammalian Species 495: 1–11). However, the longevity of the Irish hare (L. t. hibernicus Bell 1837) is entirely unknown. A total of 14 Irish hares was trapped and tagged at Belfast International Airport, Co. Antrim from February to April 2005. The sex, age (juvenile or adult) and weight of each animal were recorded. Adults were taken as those individuals >8-10 months old defined by the fusing of the notch between the apophysis and diaphysis of the tibia and humerus (Flux, J. E. C. 1970 Journal of Zoology 161: 75-123). Individual identification was made by a system of colourcoded ear tags (Roxan iD Ltd. Selkirk, Scotland) being inserted in the centre of the pinna of each ear. Each ear tag (6 × 34 mm) and puncture site was disinfected with 70 per cent ethanol prior to insertion. An adult male, #001/002 ‘Blue/Blue’, was tagged on 3 March 2005 weighing 3.8 kg and was sighted during a return site visit on 4 April 2007. An adult female, #026/003 ‘Green/Yellow’, was tagged on 15 April 2005 weighing 4.0 kg and was sighted during return visits on 25 March 2010 and 19 October 2010. The latest possible date of birth for both individuals was spring/summer 2004. Consequently, they were at least 3 years and 6.5 years old, respectively. This is the first record of minimum Irish hare longevity in the wild. These observations suggest that ear tagging does not compromise animal welfare and is an effective means of long-term monitoring. Future research may utilize capture-mark-recapture methods.

A comparative study of domestic, European and international job-related relocation

This paper explores a number of relocation outcomes for geographically mobile employees in the following three regions: Germany as the home country and destination for domestic assignments (n = 115), Western Europe (n = 116) and other countries (n = 236). The satisfaction with various aspects of the post-relocation environment, the perception of change between the pre- and post-relocation environment and the attachment to the post-relocation environment at various levels were compared between the three groups. For the European and international sub-samples differences in the ideal country and future plans were also investigated. The group that stood out most clearly was the domestic sub-sample. It emerged as the group least satisfied with their job or task characteristics, perceived significantly fewer changes in the environment and was comparatively eager to leave the site they were currently working at and the job they were currently employed in. The sometimes proposed redefinition of intra-European assignments as ‘quasi-domestic’ relocation appears to be inappropriate.

John Thompson: Seeing through China

In 1848, Karl Marx predicted that a flow of cheap commodities would be the heavy artillery which would batter down all Chinese walls and open up the country to the west (Marx, 1978, p. 477). The Scottish photographer John Thomson (1837-1921) was both chronicler of and participant in the early moments of this process. Thomson was a commercial photographer who first arrived in the Far East in 1862. He earned the moniker of 'China' in a decade-long stay during which he photographed what he considered to be the key aspects of its culture and landscape. In this body of work, Illustrations of China and its People (first published in 1874) is perhaps the most comprehensive. It explores, through two hundred photographs and accompanying texts, a series of phenomena from the macro-scale of landscape, infrastructure and industry to the smaller scales of streetscapes, domestic spaces, individual portraits, and other details of everyday life. Despite his own description of the volumes as encyclopedic, Illustrations is geographically quite limited. Thomson's explorations into the hinterland proceed up the country’s principal rivers from those coastal ports which had already been wrested into western hands during the Opium Wars (of the 1840s) and subsequently opened up to trade. This is perhaps one of the reasons why Illustrations has been described as an explicitly colonial text, a guide-book for the prospective settler whose content offered the strategic knowledge of land, culture and natural resources necessary if the territorial advantages of the coastal periphery were to extended to the interior (Jeffrey, 1981, p. 64). It can also be argued, however, that Thomson’s volume offered justification for a potential colonial presence. Faced with a civilization whose history was as sophisticated as the west, it depicts a culture that is static and moribund, its addiction to traditional values an impediment to progress. While this is perhaps most explicit in the texts of Illustrations of China, it can also be seen in the images whose uniform chemical rendering also serves to make an essentially diverse culture seem homogenous. Yet it is these images that distinguish Illustrations from previous attempts to collate China’s culture and landscape. Here, the mechanical precision of his camera captures a reality that often subverts the colonial narrative, confounding stereotypes as Thomson’s mass-produced images allow another China to emerge.

Maria Teresa Cortez. Os contos de Grimm em Portugal. A recepção dos Kinder-und Hausmärchen entre 1837 e 1910, Coimbra, Minerva (Centro Interuniversitário de Estudos Germanísticos) e Universidade de Aveiro, 2001. 531 pp.

Trabalho que investiga a recepção dos Kinder - und Hausmärchen em Portugal, fruto duma aturada e minuciosa pesquisa documental. Com efeito, Teresa Cortez passa em revista os livros e publicações periódicas enquadrados entre 1837 — data do aparecimento das primeiras traduções de contos dos KHM, no periódico lisboeta Biblioteca Familiar e Recreativa — e 1910, data a que a autora estendeu a sua pesquisa. Cada incidência da presença dos contos dos Grimm em Portugal é cuidadosamente investigada, contextualisada e analisada, Assim, à medida que vemos surgir, primeiro esparsas em revistas destinadas a um público infantil, e sem indicação de autoria, traduções (do francês) dos KHM, vamo-nos inteirando sobre o epírito e motivações do seu aparecimento, quer partindo do estudo comparativo com o texto de origem, quer de um exame da publicação de chegada, alargando-se a pesquisa aos seus editores e autores. Todo o processo de recepção dos contos de Grimm vai sendo examinado pela autora à luz dos movimentos das últimas décadas do séc. XIX e primeira do séc. XX, nomeadamente o nacionalismo neo-romântico e o positivismo.
