Barshalder 1 : A cemetery in Grötlingbo and Fide parishes, Gotland, Sweden, c. AD 1-1100. Excavations and finds 1826-1971

The prehistoric cemetery of Barshalder is located along the main road on the boundary between Grötlingbo and Fide parishes, near the southern end of the island of Gotland in the Baltic Sea. The cemetery was used from c. AD 1-1100. The level of publication in Swedish archaeology of the first millennium AD is low compared to, for instance, the British and German examples. Gotland’s rich Iron Age cemeteries have long been intensively excavated, but few have received monographic treatment. This publication is intended to begin filling this gap and to raise the empirical level of the field. It also aims to make explicit and test the often somewhat intuitively conceived results of much previous research. The analyses deal mainly with the Migration (AD 375–540), Vendel (AD 520–790) and Late Viking (AD 1000–1150) Periods. The following lines of inquiry have been prioritised. 1. Landscape history, i.e. placing the cemetery in a landscape-historical context. (Vol. 1, section 2.2.6) 2. Migration Period typochronology, i.e. the study of change in the grave goods. (Vol. 2, chapter 2) 3. Social roles: gender, age and status. (Vol. 2, chapter 3) 4. Religious identity in the 11th century, i.e. the study of religious indicators in mortuary customs and grave goods, with particular emphasis on the relationship between Scandinavian paganism and Christianity.. (Vol. 2, chapter 4) Barshalder is found to have functioned as a central cemetery for the surrounding area, located on peripheral land far away from contemporary settlement, yet placed on a main road along the coast for maximum visibility and possibly near a harbour. Computer supported correspondence analysis and seriation are used to study the gender attributes among the grave goods and the chronology of the burials. New methodology is developed to distinguish gender-neutral attributes from transgressed gender attributes. Sub-gender grouping due to age and status is explored. An independent modern chronology system with rigorous type definitions is established for the Migration Period of Gotland. Recently published chronology systems for the Vendel and Viking Periods are critically reviewed, tested and modified to produce more solid models. Social stratification is studied through burial wealth with a quantitative method, and the results are tested through juxtaposition with several other data types. The Late Viking Period graves of the late 10th and 11th centuries are studied in relation to the contemporary Christian graves at the churchyards. They are found to be symbolically soft-spoken and unobtrusive, with all pagan attributes kept apart from the body in a space between the feet of the deceased and the end of the over-long inhumation trench. A small number of pagan reactionary graves with more forceful symbolism are however also identified. The distribution of different 11th century cemetery types across the island is used to interpret the period’s confessional geography, the scale of social organisation and the degree of allegiance to western and eastern Christianity. 11th century society on Gotland is found to have been characterised by religious tolerance, by an absence of central organisation and by slow piecemeal Christianisation.

Effects of Paramuricea clavata (Risso, 1826) (Anthozoa: Plexauridae) forests on settlement of benthic species: an experimental approach

Rationale: Coralligenous habitat is considered the second most important subtidal “hot spot” of species diversity in the Mediterranean Sea after the Posidonia oceanica meadows. It can be defined as a typical Mediterranean biogenic hard bottom, mainly produced by the accumulation of calcareous encrusting algae that, together with other builder organisms, form a multidimensional framework with a high micro-spatial variability. The development of this habitat depends on physical factors (i.e. light, hydrodynamism, nutrients, etc.), but also biologic interactions can play a relevant role in structuring the benthic assemblages. This great environmental heterogeneity allows several different assemblages to coexist in a reduced space. One of the most beautiful is that characterised by the Mediterranean gorgonian Paramuricea clavata (Risso, 1826) that can contribute to above 40% of total biomass of the community and brings significant structural complexity into the coralligenous habitat. In sites moderately exposed to waves and currents, P. clavata can form high-density populations (up to 60 colonies m-2) between 20 – 70 m in depth. Being a suspension feeder, where it forms dense populations, P. clavata plays a significant role in transferring energy from planktonic to benthic system. The effects of the branched colonies of P. clavata could be comparable to those of the forests on land. They can affect the micro scale hydrodynamism and light, promoting or inhibiting the growth of other species. Unfortunately, gorgonians are threatened by several anthropogenic disturbance factors (i.e. fishing, pollution, tourism) and by climatic anomalies, linked to the global changes, that are responsible of thermal stress, development of mucilage and enhanced pathogens activity, leading to mass mortality events in last decades. Till now, the possible effects of gorgonian forest loss are largely unknown. Our goal was to analyse the ecological role of these sea fan forests on the coralligenous benthic assemblages. Experimental setup and main results: The influence of P. clavata in the settlement and recruitment of epibenthic organisms was analysed by a field experiment carried out in two randomly selected places: Tavolara island and Portofino promontory. The experiment consisted in recreate the presence and absence of the gorgonian forest on recruitment panels, arranged in four plots per type (forested and non-forested), interspersed each other, and deployed at the same depth. On every forested panel 3 gorgonian colonies about 20 cm height were grafted with the use of Eppendorf tubes and epoxy resin bicomponent simulating a density of 190 sea fans per m-2. This density corresponds to a mean biomass of 825 g DW m-2,3 which is of the same order of magnitude of the natural high-density populations. After about 4 months, the panels were collected and analysed in laboratory in order to estimate the percent cover of all the species that have colonized the substrata. The gorgonian forest effects were tested by multivariate and univariate permutational analyses of the variance (PERMANOVA). Recruited assemblages largely differed between the two study sites, probably due to different environmental conditions including water quality and turbidity. On overall, the presence of P. clavata reduced the settlement and recruitment of several algae: the shadow caused by the gorgonian might reduce light availability and therefore their growth. This effect might be greater in places where the waters are on average more clear, since at Portofino it is less visible and could be masked by the high turbidity of the water. The same pattern was registered for forams, more abundant outside gorgonian forest, probably linked with algal distribution, shadowing effect or alimentary competition. The last one hypothesis could be valid also for serpulids polychaetes that growth mainly on non-forested panels. An opposite trend, was showed by a species of bryozoan and by an hydroid that is facilitated by the presence of P. clavata, probably because it attenuates irradiance level and hydrodynamism. Species diversity was significantly reduced by the presence of P. clavata forests at both sites. This seems in contrast with what we expected, but the result may be influenced by the large algal component on non-forested panels. The analysis confirmed the presence of differences in the species diversity among plots and between sites respectively due to natural high variability of the coralligenous system and to different local environment conditions. The reduction of species diversity due to the presence of gorgonians appeared related to a worst evenness rather than to less species richness. With our experiment it is demonstrated that the presence of P. clavata forests can significantly alter local coralligenous assemblages patterns, promoting or inhibiting the recruitment of some species, modifying trophic relationships and adding heterogeneity and complexity to the habitat. Moreover, P. clavata could have a stabilising effect on the coralligenous assemblages.

Effect of Paramuricea clavata (Risso, 1826) "forest" on the benthic populations of Tremiti Islands Effetto "foresta" di Paramuricea clavata (Risso, 1826) sui popolamenti bentonici delle Isole Tremiti

Mediterranean coralligenous habitats are biogenic reefs characterised by high species diversity and built mainly by encrusting calcareous red algae, growing in dim light conditions. The global climate change and several human activities may threaten species living in these habitats, especially some of those that are considered particularly relevant in structuring and in maintaining the complexity and diversity of the benthic assemblages. Among them, the red gorgonian, Paramuricea clavata (Risso, 1826), which can form dense populations, in the last decades showed worrying mass mortality events. Understand the role of this “animal forests” in the coralligenous assemblages is of fundamental importance in order to design appropriate monitoring programs and conservation policies, especially in the marine protected areas. For this purpose, benthic assemblages were studied in presence and absence of red gorgonians at two sites at the Tremiti islands. Overall, the benthic assemblages significantly differed among sites, nevertheless in both places, clear differences between assemblages associated and not associated to the gorgonian forests were found. In particular, encrusting corallinered algae were significantly more abundant in the gorgonian understories at both sites. This result indicates that the gorgonians may promote the development of calcareous algae, which are the main builders of the coralligenous habitats. Moreover species diversity resulted higher in the assemblages associated to the gorgonians. The present study highlights the role of Paramuricea clavata as a relevant ecosystem engineer in the coralligenous habitats.

Le Havre. Forme e caratteri dello spazio urbano nel progetto di Auguste Perret

Oggetto del presente studio è il progetto di ricostruzione del centro urbano di Le Havre ad opera di Auguste Perret. Suo obiettivo è il riconoscimento di quell’idea di città posta a fondamento del progetto, per il quale ci si propone di indagare il senso e le grammatiche costitutive della sua forma. Quella di Le Havre costituisce una dimostrazione di come una forma urbana ancora compatta ed evocativa della città storica possa definirsi a partire dalle relazioni stabilite con gli elementi della geografia fisica. Nei suoi luoghi collettivi e monumentali, che rimandano chiaramente a una cultura dell’abitare che affonda le proprie radici nella più generale esperienza della costruzione della città francese, la città riconosce un valore formale e sceglie di rappresentare il proprio mondo civico dinanzi a quei grandi elementi della geografia fisica che costituiscono l’identità del luogo nel quale questa si colloca. Sembra infatti possibile affermare che gli spazi pubblici della città atlantica riconoscano e traducano nella forma della Place de l’Hôtel de Ville le ripide pendici della falesia del Bec-de-Caux, in quella della Porte Océane l’orizzonte lontano dell’Oceano, e nel Front-de-mer Sud l’altra riva dell’estuario della Senna. Questa relazione fondativa sembra essere conseguita anche attraverso la definizione di un’appropriata grammatica dello spazio urbano, la cui significatività è nel fondarsi sull’assunzione, allo stesso tempo, del valore dello spazio circoscritto e del valore dello spazio aperto. La riflessione sullo spazio urbano investe anche la costruzione dell’isolato, sottoposto a una necessaria rifondazione di forma e significato, allo scopo di rendere intellegibile le relazioni tra gli spazi finiti della città e quelli infiniti della natura. La definizione dell’identità dello spazio urbano, sembra fondarsi, in ultima analisi, sulle possibilità espressive delle forme della costruzione che, connotate come forme dell’architettura, definiscono il carattere dei tipi edilizi e dello spazio da questi costruito.

Ruolo della gorgonia Paramuricea clavata (Risso 1826) nei popolamenti epibentonici coralligeni dell'Isola d'Elba

The red gorgonian Paramuricea clavata is considered a key species in Mediterranean coralligenous habitats and, when present at high density, its colonies may develop “gorgonian forests”, which are three-dimensional structures that increase habitat complexity. Mediterranean coralligenous habitats support high biodiversity but the structure and heterogeneity of communities can be strongly modified by several kinds of human-derived impacts. The global environmental change and human activity could threaten the coralligenous habitats and during the last few decades, Mediterranean suspension feeders have been involved in mass mortality events, in which P. clavata was one of the most affected. Without the complex three-dimensional structures formed by P. clavata, many benthic species may have not adequate sheltering and feeding opportunities. The aim of the present study was to investigate the ecological role of Paramuricea clavata in coralligenous habitats by comparing epibenthic assemblages established inside and outside gorgonian forests. This study was carried out in four sites randomly chosen, along the south-east coast of Elba island (north-western Mediterranean). The structure of the epibenthic assemblages were significantly different between area with and without gorgonians. Main differences concern very important taxa in the coralligenous bioconstruction processes like the encrusting red algae, Peyssonnelia spp. and Halimeda tuna, which were more abundant in presence of gorgonians. On the contrary, algal turf, mucilaginous algae and the invasive seaweed Caulerpa cylindracea were more abundant in areas without P. clavata. The presence of gorgonians may have a positive effect also on species diversity. The results of this study highlight the ecological role of P. clavata in the coralligenous habitats.

The Copper Country Strike of 1913-1914 in Finnish Newspapers

The purpose of this study is to take a closer look at media response in Finland concerning the 1913-14 Michigan Copper Strike and depict how the strike was presented in the Old Country and its main newspapers. I shall take a closer look at the 1913-14 issues of Työmies (social democrat), Helsingin Sanomat (liberal), and Uusi Suometar (conservative) for ideological views of the strike. Furthermore, and in terms of close reading and cross-referencing, how did these newspapers in Finland see the strike and the strike’s outcome? Editorial notes and letters from the public shall both be included. Special attention will be given to the notions of transnational solidarity between Finnish-American and Finnish labor activists.

Father Dietz, the Catholic Church and the 1913 Michigan Copper Strike

Labor Historian Marc Karson has singled out “labor priest” Peter E. Dietz as one of the strongest proponents for the active implementation of the Catholic Church’s 1890’s labor encyclical Rerum Novarum in the daily practice of American Catholics. Biographer Sister Mary Harrita Fox pointed out that in his work, Dietz “was particularly concerned over the role of the church in the copper strike in Upper Michigan.” This “particular concern” should be noted since the 1913 strike was one of the only disputes where Dietz went out of his way to visit and become actively involved. Why the keen interest? This presentation will review the impetus for the huge effort which brought Peter E. Dietz to the Copper Country and solely to that dispute alone, the resulting visit and report that he made concerning the strike, the important role he believed this visit and stance in the Copper Strike had in the future of the Church’s relationship to the US labor movement. The presentation will look at both what Dietz thought would occur as a result of his 1913 trip to the Keweenaw and what actually happened in this pivotal pre-World War One era event. The paper will put Father Peter E. Dietz and the Catholic Church into the larger frame of how religion has been viewed within the history of the Strike.

Gender on the Range: Feminine Strategies in the 1913 Michigan Copper Strike

In the autumn of 1913, a small, remote Michigan mining community attracted national attention as miners and management found themselves embroiled in a conflict that would prove no easy victory for either side. The strike came as a shock to management, who, with the help of a nearly perfected paternal system, had come to expect a generally docile and compliant workforce. But what was even more shocking was the involvement of the miners’ wives in the strike effort, and the lengths they went to in order to keep men from crossing the picket line. This paper focuses on that effort, arguing that the women of the Michigan copper country developed strike strategies that were derived from their domestic experience, and justified their involvement through maternal arguments. However, these public actions allowed the management to disregard the respect and courtesy generally given to the domestic sphere as police and private agents perpetrated a number of home invasions in an attempt to break the strike. The involvement of women in male dominated labor disputes (mining, steel productions) has been largely ignored in the literature due to their indirect connection to the company as wives and not workers. This paper seeks to remedy this gap, and gain a better understanding of that indirect relationship. Sources include newspaper articles, private correspondence, public investigation records, and oral histories, found largely in the Michigan Tech Archives and Copper Country Historical Collections, Michigan Technological University, Michigan.

“Beneath the Starry Flag”: the Flags and Songs of the 1913-14 Michigan Copper Strike as Image-making in the American Labor Movement

The 1913-14 Michigan copper strike is unlike many American labor actions of the period in that it did not include red flags or socialist anthems. Many of the most familiar photographs of the strike involve American flags, not red ones. Similarly, the songs mentioned in journalistic accounts of the strikers are American Civil War songs, not popular labor songs of the period. The few newly-written songs about the strike, published in the local newspapers, seem cautiously polite and espouse values such as patriotism, liberty and human rights. During a time when sections of the "friendly" press were concerned with labor presenting the correct image and avoiding unfavorable associations, the Copper Country strikers, and the W.F.M., seem to have been attempting to create a fresh narrative regarding what this strike was (and what it was not). This paper will consider elements of the Copper Country strike in the light of media coverage, prior to July 1913, of several American labor topics that might have influenced the way the strike was presented. Particular attention will be given to photographs, songs, and accounts from the 1912 Lawrence textile strike, as well as contemporaneous critiques of labor song lyrics. Most of this commentary will be drawn from the labor and socialist press, demonstrating that the 1913-14 Michigan copper strike occurred during a period in which the labor movement was struggling to craft and image that would display it as it wished to be seen.
