Geogenic and atmospheric sources for volatile organic compounds in fumarolic emissions from Mt. Etna and Vulcano Island (Sicily, Italy)

In this paper, fluid source(s) and processes controlling the chemical composition of volatile organic compounds (VOCs) in gas discharges from Mt. Etna and Vulcano Island(Sicily, Italy) were investigated. The main composition of the Etnean and Volcano gas emissions is produced by mixing, to various degrees, of magmatic and hydrothermal components. VOCs are dominated by alkanes, alkenes and aromatics, with minor, though significant, concentrations of O-, S- and Cl(F)-substituted compounds. The main mechanism for the production of alkanes is likely related to pyrolysis of organic-matterbearing sediments that interact with the ascending magmatic fluids. Alkanes are then converted to alkene and aromatic compounds via catalytic reactions (dehydrogenation and dehydroaromatization, respectively). Nevertheless, an abiogenic origin for the light hydrocarbons cannot be ruled out. Oxidative processes of hydrocarbons at relatively high temperatures and oxidizing conditions, typical of these volcanic-hydrothermal fluids, may explain the production of alcohols, esters, aldehydes, as well as O- and S-bearing heterocycles. By comparing the concentrations of hydrochlorofluorocarbons (HCFCs) in the fumarolic discharges with respect to those of background air, it is possible to highlight that they have a geogenic origin likely due to halogenation of both methane and alkenes. Finally, chlorofluorocarbon (CFC) abundances appear to be consistent with background air, although the strong air contamination that affects the Mt. Etna fumaroles may mask a possible geogenic contribution for these compounds. On the other hand, no CFCs were detected in the Vulcano gases, which are characterized by low air contribution. Nevertheless, a geogenic source for these compounds cannot be excluded on the basis of the present data

An early warning system for highly pathogenic viruses borne by waterbird species and related dynamics of climate change in the Caspian Sea region: Outlines of a concept

Aim. Formulation of the outlines of the concept of ViEW (Viral Early Warning) which is intended as a long term system of multidisciplinary transboundary cooperation between specialist institutions of all five Caspian region states to research, regularly monitor and share data about the generation, transmission and epidemiology of avian‐borne pathogens and their vectors in the region, and the ways climate change may affect these processes.Material and Methods. The concept is based on the multidisciplinary experience of the authors in researching the processes incorporated in the ViEW concept and on an in‐depth survey of the literature involved.Results. The outlines of the ViEW concept are presented in this study for review and comment by interested parties and stakeholders.Conclusion. Review of activities and opinions of specialists and organizations with remits relating to the development, establishment and maintenance of ViEW, indicates that such a system is a necessity for global animal and human health because of the role that the Caspian region plays in the mass migration of species of waterbird known as vectors for avian influenza and the already evident impacts of climate change on their phenologies. Waterbirds frequenting the Caspian Sea littorals and their habitats together constitute a major potential global hotspot or High Risk region for the generation and transmission of highly pathogenic avian influenza viruses and other dangerous zoonotic diseases

“University of the People” – the third mission of Dagestan State University: an innovative approach to sustainability policy

Aim. To develop an effective and innovative policy approach to Dagestan State University’s third mandated mission to support sustainable community development by acknowledging and enhancing through specialist education the undervalued knowledge capital inherent in individuals and organizations throughout the community.Discussion. Dagestan State University has 90 years of experience in providing support for the people of Dagestan in scientific research and higher education and is cognizant of the deep reservoir of community knowledge and competencies in articulating aspirations for sustainable development. On this basis, the university’s Institute of Ecology and Sustainable Development is instituting an innovative community engagement program, the University of the People, to deliver effective scientific support for such development through co‐creative collaborations which draw on and enhance community knowledge in the diverse regions of the republic. In consultation with the administration and community stakeholders of the alpine Tsumadinskiy district of the Dagestan Caucasus, through the present policy document a launch phase of the University of the People program has been formulated for 2022 which will provide year‐long local vocational guidance to schools and an annual “Summer Field Faculty” which will undertake research, developmental needs analysis and offer in‐service specialist training opportunities and support for local experts and administrations in implementing their desired sustainability initiatives. Following literature research and fieldwork in 2020‐2021, the first outcome of the regional sustainability initiative, “Conserving the Koisu: Sustaining the Mountain Fastness of the Upper Andiiskoe River – A Uniquely Surviving Socio‐Ecological Continuum in the Dagestan Caucasus”, has been completedConclusion. Implementation of the University of the People concept has the potential to effectively harness the vast resources of traditional knowledge of individuals and local bodies in regional sustainable development by providing communities with concrete support and interaction of university specialists and educators in ecology and sustainable development. It is hoped that the program will stimulate and enable members of the community to themselves attain tertiary qualifications in these fields, who, in turn, will create a future knowledge resource for continuing local applications of sustainable development principles. The concept has potential for application to other societies in the Caspian region which share similar histories and challenges

The Solar Stag of the Chamalals and Tindals and other masonry petroglyphs in the upper Andiiskoe Koisu region of Dagestan and their relationships to similar phenomena in the mountain communities of the Caucasus: Socio-ecological and historical perspectives

Aim. Following the discovery of a number of iconographically unique masonry petroglyphs depicting a red deer solar stag (i.e. bearing the sun between its antlers) in settlements of the Chamalal ethno‐linguistic group in the upper Andiiskoe Koisu region of the Tsumadinskiy district of Dagestan, the aim of the research has been: (1) to survey the region to ascertain whether other images of this nature existed and to understand the relationship of the corpus to other petroglyphs produced within the Avar‐Ando‐Dido metacultural zone and of neighbouring ethnic groups in the Caucasus; (2) to study the evolution and meaning to the community of the petroglyphic imagery and (3) to understand the mechanisms by which peoples of the Caucasus shared and adapted polytheistic belief systems arising from the deep past following their conversion to Christianity and Islam.Materials and Methods. Research activities involved field surveys of traditional buildings within the ethno‐linguistic enclaves of the upper Andiiskoe Koisu which might contain masonry petroglyphs and their photographic documentation. A thorough survey of the scientific literature impacting on this field in the Caucasus was undertaken in the libraries and institutions of Dagestan, Moscow and Saint Petersburg. This data added to the documentation of masonry petroglyphs already undertaken in the Gidatli communities of the upper Avarskoe Koisu region.Results. Field surveys resulted in the discovery of more petroglyphs of the solar stag iconography both within Chamalal territory and that of the neighbouring Tindals as well as other petroglyphs of interest in neighbouring republics of the North Caucasus. A socioecological assessment of local habitats which might have sustained both red deer and bezoar goat (the principal game animals since human presence in the region) indicated that the bezoar goat inhabited the territories of both groups but were now rarely found in Chamalal lands. While red deer did inhabit the forests of the Tindals, it appears that they never frequented those of the Chamalals, who must have travelled to hunt them in forests further to the south.Conclusion. The research confirmed the presence of a unique corpus of petroglyphic imagery attesting to beliefs in a solar stag which may date back to period of man’s re‐inhabiting the upper Andiiskoe Koisu region in the early Holocene. Indigenous beliefs relating both to the red deer and the bezoar goat initially represented in rock face petroglyphs of the eastern Dagestan piedmonts and rock paintings of the mountainous regions were by the late Bronze Age represented on masonry blocks used in building in the Avar‐Ando‐Dido metacultural zone. As Christianity spread in Transcaucasia and the Great Caucasus Range, including north‐western Dagestan, indigenous images representing the solar stag were conflated with those of the popular Christian cult of the Miracle of Saint Eustace, resulting in the unique petroglyphs of the solar stag common t

Verkhnee Gakvari: The contribution of adat, religious beliefs and public education to collective environmental management in an agro‐pastoral community in the Dagestan high Caucasus

Aim. To examine the contribution structured systems of social mores (adat) and religious and secular public education have made to developing and sustaining socio‐ecological environment management in one community, Verkhnee Gakvari, in the upper valley of the Andiiskoe Koisu in the Dagestan Caucasus, from deep antiquity to the present day. Discussion. The research involved an extensive review of the relevant literature and on‐line resources dedicated of the region. Communities were visited across the region and discussions were undertaken with their representatives, as well as with other stakeholders. A particular emphasis was placed on the exemplary system of environmental education provided at the Verkhnee Gakvari School and its positive impact in sustaining the socio‐ecological production landscape of its territory. Significant progress was made in researching and documenting the range of issues fundamental to understanding the formation and continuity of the inter‐dependencies with nature and the cultural landscapes unique to these agro‐pastoral cultures of the upper Andiiskoe Koisu. This includes a comprehensive documentation of the contributions the Verkhnee Gakvari School has made to the preservation of its community’s socio‐ecological production landscape.Conclusion. Verkhnee Gakvari and other traditional communities of the upper Andiiskoe Koisu present a unique multi‐millenial cultural continuum of global significance for understanding the evolution of human society and are a remarkable survival in Europe of successful and harmonious socio‐ecological production landscape interdependencies. As the combined impacts of modern society and climate change now inevitably impinge upon the ability of the inhabitants of this ancient homeland to sustain the benefits which they have so successfully crafted from their environment, the region is in priority need of national and international recognition and support

Different expressions of the same mode: a recent dialogue between archaeological and contemporary drawing practices

In this article we explore what we perceive as pertinent features of shared experience at the excavations of an Iron Age Hillfort at Bodfari, North Wales, referencing artist, archaeologist and examples of seminal art works and archaeological records resulting through inter-disciplinary collaboration. We explore ways along which archaeological and artistic practices of improvisation become entangled and productive through their different modes of mark-making. We contend that marks and memories of artist and archaeologist alike emerge interactively, through the mutually constituting effects of the object of study, the tools of exploration, and the practitioners themselves, when they are enmeshed in the cross-modally bound activities. These include, but are not limited to, remote sensing, surveying, mattocking, trowelling, drawing, photographing, videoing and sound recording. These marks represent the co-signatories: the gesture of the often anonymous practitioners, the voice of the deposits, as well as the imprint of the tools, and their interplay creates a multi-threaded narrative documenting their modes of intra-action, in short our practices. They occupy the conceptual space of paradata, and in the process of saturating the interstices of digital cognitive prosthetics they lend probity to their translations in both art form and archive

Some cultural consequences in Spain of the Spanish Invasion of Morocco 1859-60

This article argues is a contribution to the study of interrelationships between colonialism, art, and literature in the nineteenth century. The article argues that the Spanish invasion of Morocco in 1859 led to contradictions and tensions within liberal nationalism, not least because of concerns about the tensions between the need for military reassertion of Spain and the respect for the independence of nations. This led to some reconfiguration of Spanish intellectuals' already complex relationship with North Africa and Islam. A major, perhaps surprising consequence of this reconfiguration, was some equation of Moroccan identity with a monotonous surface that was resistant to the gaze. In consequence, the Catalan painter Fortuny's crucial experience of Morocco led him to value near blank surfaces, and thus to make a major contribution to the origins of modern art

Epistemic injustice: A role for recognition?

© The Author(s) 2017. My aim in this article is to propose that an insightful way of articulating the feminist concept of epistemic injustice can be provided by paying significant attention to recognition theory. The article intends to provide an account for diagnosing epistemic injustice as a social pathology and also attempts to paint a picture of some social cure of structural forms of epistemic injustice. While there are many virtues to the literature on epistemic injustice, epistemic exclusion and silencing, current discourse on diagnosing as well as explicating and overcoming these social pathologies can be improved and enriched by bringing recognition theory into the conversation: under recognition theory, social normative standards are constructed out of the moral grammar of recognition attributions. I shall argue that the failure to properly recognize and afford somebody or a social group the epistemic respect they merit is an act of injustice in the sense of depriving individuals of a progressive social environment in which the epistemic respect afforded to them plays a significant role in enabling and fostering their self-confidence as rational enquirers. Testimonial injustice is particularly harrowing, because it robs a group or an individual of the status of a rational enquirer, thereby creating an asymmetrical cognitive environment in which that group or individual is not deemed one’s conversational peer. Hermeneutical injustice is particularly harrowing, because asymmetrical cognitive environments further entrench the normative power of ideology

An experimental study on the effect of visual tasks on discomfort due to peripheral glare

This article concerns discomfort due to sources of glare in the peripheral visual field. A visual task is needed to maintain foveal fixation at a known location and in past studies the tasks have ranged from a simple fixation mark to a task requiring greater cognitive attention such as reading. It was hypothesized that these different approaches to control visual attention would influence the evaluation of discomfort. This article reports an experiment which compared evaluations of discomfort when using the two visual tasks, a simple circle and a pseudo-text reading task, and two procedures, category rating and luminance adjustment. The results from both procedures confirmed the hypothesis: a lower degree of discomfort was expressed in the pseudo-text trials than in trials with the circular fixation mark
