Stranger in our Midst::The Becoming of the Queer God in the Theology of Marcella Althaus-Reid
No full textThis is the author accepted manuscript. The final version is available from the publisher via the link in this record.Book description: Marcella Althaus-Reid was one of the most fascinating and controversial theologians of the twentieth and early twenty-first century. Her strong personality and her iconoclastic work inspired a whole generation of theologians in the UK and worldwide. Marcella's creative life was cut short by her death from cancer in 2009. Yet she lives on, not least in those who have been inspired by her work and continue to engage with it. "Dancing Theology in Fetish Boots" draws together a number of world-class scholars and others who engage with the main themes of Marcella's work and show how the critical and controversial conversations which Marcella has begun can and do continue. It is therefore far more than a Festschrift, but a celebration of an intellectual life Marcella-style

From ethnobotany to experimental research: the therapeutic properties of Sicilian hellebore
No full textIn Sicily, the genus Helleborus (Ranuculaceae) is only represented by H. bocconei subsp. siculus (= H. bocconei subsp. intermedius). In some mountain areas of the Island, the rhizomes of this plant, harvested in a particular month of the year (May) and dried, are used in traditional veterinary practice for treating pneumonia in domestic animals, cattle and horses in particular. The same usage – with rhizomes of other Helleborus species or subspecies – is reported from various other areas of Mediterranean Europe. Phytochemical tests have permitted the isolation and characterization of new biologically active molecules. The extracts of rhizomes and aerial parts of the plant were shown antibacterial properties. Some compounds, isolated from the methanolic extract of the rhizomes, were shown to be cytotoxic. In addition, morpho-anatomical studies have revealed the presence of different endophytic and commensal fungi in all organs of the plant, which could be isolated and cultured. One of the isolates has been identified as the endophytic fungus Botrytis byssoidea, which is also widely present in the soil. Further fungal isolates include Chaetomium strumarium, strain RR1, an endophytic ascomycete the identity of which was confirmed by molecular analyses. When cultured, it developed plentifully; the filtered broth from these cultures was used in antibiotic property assays. The tests were positive; the detailed results are forthcoming. They support our initial hypothesis, that the therapeutic effect the hellebore’s rhizomes extract is due to metabolites produced by an endophytic fungus. It remains to be seen whether the plant itself, devoid of the microfungus, produces the same therapeutically effective metabolites that are present in the extracts of plants from the wild or from outdoor cultivation. The study of the Sicilian hellebore, beyond its biological interest, has potential for its relevance for therapeutic applications both in veterinary and human medicine

Convenient oxidation of alkylated phenols and methoxytoluenes to antifungal 1,4-benzoquinones with hydrogen peroxide (H2O2)/methyltrioxorhenium (CH3ReO3) catalytic system in neutral ionic liquid
No full textAlkylated phenol and methoxytoluene derivatives were catalytically and selectively oxidized to the corresponding 1,4-benzoquinones in good conversions and yields. Reactions were performed with hydrogen peroxide (H2O2)/methyltrioxorhenium (CH3ReO3) in 1-butyl-3-methylimidazolium tetrafluoroborate [bmim]BF4, aneutral ionic liquid. Compounds were tested in vitro for their antifungal activity against the growth of several widespread soil fungi. Some of them were proved to be potent inhibitors of Fusarium sp. than ketoconazole, a commercially available and expensive antifungal agent. (c) 2006 Elsevier Ltd. All rights reserved
DNA-Based Taxonomy in Ecologically Versatile Microalgae: A Re-Evaluation of the Species Concept within the Coccoid Green Algal Genus Coccomyxa (Trebouxiophyceae, Chlorophyta).
No full textCoccomyxa is a genus of unicellular green algae of the class Trebouxiophyceae, well known for its cosmopolitan distribution and great ecological amplitude. The taxonomy of this genus has long been problematic, due to reliance on badly-defined and environmentally variable morphological characters. In this study, based on the discovery of a new species from an extreme habitat, we reassess species circumscription in Coccomyxa, a unicellular genus of the class Trebouxiophyceae, using a combination of ecological and DNA sequence data (analyzed with three different methods of algorithmic species delineation). Our results are compared with those of a recent integrative study of Darienko and colleagues that reassessed the taxonomy of Coccomyxa, recognizing 7 species in the genus. Expanding the dataset from 43 to 61 sequences (SSU + ITS rDNA) resulted in a different delimitation, supporting the recognition of a higher number of species (24 to 27 depending on the analysis used, with the 27-species scenario receiving the strongest support). Among these, C. melkonianii sp. nov. is described from material isolated from a river highly polluted by heavy metals (Rio Irvi, Sardinia, Italy). Analyses performed on ecological characters detected a significant phylogenetic signal in six different characters. We conclude that the 27-species scenario is presently the most realistic for Coccomyxa and we suggest that well-supported lineages distinguishable by ecological preferences should be recognized as different species in this genus. We also recommend that for microbial lineages in which the overall diversity is unknown and taxon sampling is sparse, as is often the case for green microalgae, the results of analyses for algorithmic DNA-based species delimitation should be interpreted with extreme caution
A 4th millennium temple/palace complex at Arslantepe-Malatya. North-South relations and the formation of early state societies in the northern regions of Greater Mesopotamia
No full textThis article reconsiders the nature of relations between the southern and northern communities of "Greater Mesopotamia " during the Late Uruk period and- the effects that the so-called, expansion of southern groups had on the formation of the first state societies in the northern regions of Syria and Eastern Anatolia. The author stresses the earlier historical roots of the unitv of Greater Mesopotamia as well as the importance of local components in the development of new centralised political structures. The changes in interregional and intersite relations during this time also seem to be inainly a result of structural changes which took place in the individual societies both in the north and, in the south. The analysis is based on the emblematic case of Arslantepe (Malatva), where the wealth of data from a large public area has made it possible to reconstruct an earlv "State" svstem stronglv interacting with the southern societies, but based on the growth of local organisational structures.Nouvelle étude de la nature des rapports entretenus entre les communautés du Nord, et du Sud de la, « Greater Mesopotamia » au cours de l'Uruk récent, plus particulièrement de l'influence que l'expansion de groupes venant du Sud a pu avoir, dans les régions septentrionales de la Syrie et de l'Anatolie orientale, sur la naissance et l'évolution des premières formes de l'État. Sont mises en évidence aussi bien les racines historiques de l'unité culturelle qui caractérise la « Greater Mesopotamia » que l'importance des composantes locales et, le rôle que les unes et les autres jouèrent dans le développement d'organisations politiques centralisées. Les changements observés tant au niveau inter- régional qu 'au niveau des sites à cette époque sont dus principalement aux changements structuraux qui prirent place, et dans les sociétés du nord et dans celles du sud. Cette analyse est fondée sur le cas exemplaire que nous offre le site d'Arslan Tepe (Malatya) où la richesse des données provenant d'une vaste zone d'édifices publics a permis de proposer une reconstruction d'une proto-organisation d'un État avant de fortes interactions avec les sociétés du Sud, mais qui, en même temps, reposait sur le développement de structures tout à fait locales.Frangipane Marcella.

UNESCO, Adult education and political mobilization
No full textIn this article the author examine the type of mobilization processes that occur via interactions between the UNESCO and other political actors, and how these processes led to the creation of standard-setting and monitoring instruments, like the Belém Framework for Action (UNESCO 2009) and the Global Report on Adult Learning and Education (UIL 2003, 2013). The findings point at three concurrent processes or modes of mobilization in adult education: landmarking, brokering and framing. Landmarking refers to the process of co-constructing a shared past for a broad set of actors with policy will in adult education; Brokering captures the process of supporting the transaction of values, ideas and information to envision a viable future for adult education; finally framing addresses the structuring of information and intentions to produce materials changes at governmental level in the field of adult education. Drawing on different data sources, for each mode the author present and discuss few of its incidences and visible marks
Global polity in adult education and UNESCO: landmarking, brokering and framing policy
No full textAknowledging the complexity of local–global interconnections, the author argues for the adoption of a global polity perspective in adult education, here applied to study mobilisation processes that occur through UNESCO. The findings point to three processes that cross geopolitical borders and professional interests: ‘landmarking’, by which a shared sense of a common past is created; ‘brokering’, which helps shape a common future direction; and ‘framing’, which is used to convert ideational landscapes into material government-led actions. The theoretical perspectives and analytical insights presented could be used in analogous studies in other areas of education or with a focus on different political actors
