Mobility and migration in Byzantium: who gets to tell the story?

This article underlines the importance of approaching written sources for what they are: authorial constructs. This is true also for depictions of mobility and migration. Byzantine authors instrumentalized these for their own purposes beyond the event at hand. Authorial focus, along with the requirements of the chosen literary genre, is also the reason for the different scales of actors that appear in these texts, whether large blurry masses of nameless people, smaller groups with a distinct profile, or finely drawn individuals.     

The Politics of Masculinity in the (Homo-)Sexual Discourse (1880 to 1920)

Masculinity became an important topic of discussion around 1900,not only as reaction to the growing women's movement, but alsoa result of new developments in the medical and sexual sciences.In the late nineteenth century medical doctors began to takea sustained interest in same-sex sexual relations between men,giving rise to the concept of the homosexual man as feminizedand dangerous to the social order. While the medical conceptof the ‘third sex’ could also be –and was– used for emancipatory purposes by early advocates ofhomosexual rights, a group of masculinists rejected these discriminatorycharacterizations by insisting on their masculinity and arguingthat state and society were in fact based on male bonding. Thesemasculinist strategies, which sought to integrate male–malesexuality into hegemonic masculinity, represented resistanceagainst discrimination, but they also served to shore up andmodernize hegemonic structures that discriminated against womenand Jews.     

Experimental and Analytical Investigation on the Corner Failure in Masonry Buildings: Interaction between Rocking-Sliding and Horizontal Flexure

ABSTRACT

The failure mechanism of corners in masonry buildings has frequently been observed in seismic scenarios, but only a few works and no experimental investigations devoted to it are available in the literature. In this aritcle, the experimental behavior of a simple masonry corner is first analyzed, by simulating the seismic horizontal actions through a progressive tilting of the supporting base. Then, the conditions of the onset of two possible failure modes are analytically formulated: they are the rocking-sliding and the horizontal flexure mechanism. A three-dimensional macro-block model with frictional joints is used to analyze these mechanisms, while the crack patterns and the load factors are derived through the kinematic approach of the limit analysis. The evaluation of the in-plane frictional resistances involved by the rocking-sliding mechanism is performed by applying a reliable criterion previously proposed, while for the torsion strength involved in the horizontal flexure mechanism, simplified yield conditions are adopted and a possible criterion is also introduced to take into account the actual reduction of the contact surfaces. Last, the experimental findings are compared and critically interpreted in light of the analytical results and the influence of the main parameters on the prevailing mechanism is highlighted.     

Bone damage patterns found in the avian prey remains of crested caracara Caracara plancus (Aves,Falconiformes)

The following paper presents the results of the analysis of the avian prey bones found in uneaten remains of crested caracara (Caracara plancus, Aves, Falconiformes) from La Pampa province, Argentina. Anatomical parts representation and taphonomic modifications were evaluated and compared to results of the evaluation of bone remains recovered from crested caracara’s pellets and to previous studies of other diurnal birds of prey. The results suggest a preferential consumption of some body parts of avian prey, as evidenced in the high frequency of wing elements in the uneaten prey remains. This analysis helps to support interpretative data concerning the origins of avian remains in the zooarchaeological and paleontological record, and contributes to the knowledge of a common predator found throughout diverse environments in South America.     

Peripheral creativity: temporary cultural uses as alternatives to inefficient policies?

ABSTRACT

The article focuses on temporary and improvised cultural spaces in marginalized neighbourhoods of Rio de Janeiro, Brazil. They are presented here as alternatives to current urban and cultural policies, often based on international ‘best practices’ models with exclusionary and segregating consequences. It begins with a brief overview into North American and Western European cultural planning policies. It then analyses the instability of cultural policies in Brazil, highlighting that, after a period of State recognition of bottom-up actions, administrators have turned to a contradictory planning scheme that mixes outdated and recent international trends, leading lower-income inhabitants to self-build their own cultural spaces. Unlike many products of today’s global strand of ‘tactic urbanism’, Rio’s temporary spaces are politically charged territories of resistance. An example is ‘Cine Taquara’ – an improvised cinema and debate forum that illustrates how, in an unequal city, such initiatives can do more towards social inclusion than ready-made models.     

Microscope observations and DNA analysis of wine residues from Roman amphorae found in Ukraine and from bottles of recent Tuscan wines

Morphological analysis by light and electron microscopy was conducted on wine residues from second century Roman amphorae found in Myrmekion (Ukraine). The results of the archaeological samples were compared with residues formed in bottles of wine from Tuscan vineyards, corked between 1969 and 1977 without filtration and enzyme or biochemical processing. Staining and histochemical observation of the archaeological and recent residues detected nucleic acids. Molecular analysis was also performed using nuclear microsatellite SSRs markers having high polymorphism to study genetic relationships. Genotype profiles of archaeological and recent residues were compared with contemporary cultivars in a data bank. Low homology of genotype profiles of all residues, and oral evidence, confirmed the presence of autochthonous varieties in recent wines and enabled indirect assessment of varieties detected in the archaeological material. The results confirmed that the archaeological material could be related to Sangiovese and indicated Roman wine trade as far afield as Ukraine, whereas the recent residues provided evidence of disappearing native Tuscany cultivars like Gorgottesco, Mammolo, Verdello, Rossone and Tenerone, used for table wines until the late seventies.
