Dislocations and ecologies. The disruption of the urban experience of London in Peter Ackroyd, Iain Sinclair and Gilbert & George

London exerts attraction and repulsion upon travellers, writers and artists alike. \ud Its past is overshadowed by the never-ending process of change, yet a close \ud investigation helps unveiling hidden parts of a collective memory. Peter \ud Ackroyd, Iain Sinclair and Gilbert & George have explored the memory of \ud London through the prism of cultural studies, psychogeography or \ud contemporary art. London: The Biography by Peter Ackroyd, Lights Out for the \ud Territory, London Orbital by Iain Sinclair and the 20 London E 1 Pictures by \ud Gilbert & George may serve as a basis for retrieving fragile realms of memory. \ud We may wonder whether these realms cannot be likened to « ecology of \ud knowledge ». If ecology designates an environment regulated by specific rules \ud and mechanisms, what do “ecologies of knowledge” refer to in the urban \ud context? Besides, the nature of the relationship between the experience of \ud London and the ecology of knowledge prompts questions. Does the experience \ud of London dislocate the artistic universes created by Peter Ackroyd, Iain Sinclair \ud and Gilbert & George? Or do the artistic works partake in the dislocation of \ud urban experience? My contention in this paper is to unveil the ways in which \ud the polymorphism of the city is translated into writerly and iconographic codes. \ud As the understanding of the urban ecology keeps receding, similarly the works \ud adopt process and metamorphosis as structuring principles. First, the \ud destabilising exploration of London shall be assessed by its impact upon the \ud physical experience, and the renegotiation of concepts such as body, \ud empiricism, and the spirit of the place. Then, the frustrating exploration of \ud London may be analysed through literary and artistic devices that echo the \ud dislocation in the works. Eventually, these works will lead us to consider the dis-membering of the city body as the only means to the re-membering of London.Londres ejerce atracción y repulsión entre los viajeros, artistas y escritores.

Armeno-Aethiopica in the Middle Ages: Geography, Tales of Christianization, Calendars, and Anti-Dyophysite Polemics in the First Millennium

Research for this article had the purpose of exploring medieval Armenian–Ethiopian connections. The investigations revealed three main contexts where Ethiopia and Ethiopians feature in the Armenian sources of the first millennium, without necessarily implying real-life encounters. Firstly, the earliest Armenian texts locate Ethiopia and discuss the genealogy of its people in line with the biblical account of the Diamerismos, as well as notions based on Eusebius of Caesarea’s Chronicle translated into Armenian from Syriac in the fifth century. Each author, then, interpreted this information according to his narrative needs or the purpose of a given composition. The discussion of these sources reveals the circulation of classical and Hellenistic notions on Ethiopia and the Ethiopians in Armenian, too, such as the confusion between Ethiopia, Arabia, and India, as well as anthropological or spiritual features attributed to Ethiopians already by classical authors. Secondly, the article analyses a series of calendrical treatises, starting with one authored by the seventh-century polymath Anania Širakac‘i, that passed on a short tale about a sixth-century gathering of scholars in Alexandria in order to determine the date of the Easter and establish tables for its calculation in the future. An Ethiopian wise man Abdiē was part of this international endeavour too, according to this tradition, and his presence marked Ethiopia as part of the eastern Mediterranean learned world, with its own cultural traditions. Armenian language hemerologia also preserved month names in Gǝʿǝz,  reproduced in the Appendix. Thirdly, the article draws attention to a completely new way of viewing Ethiopia in ninth- to eleventh-century Armenian anti-dyophysite (antiByzantine) treatises where the Armenian Church and its doctrines or ritual practices were imagined as part of a vast, non-dyophysite orthodox world that included the Ethiopian Church. Intriguingly, this argumentative technique, formulated in terms that one may callanti-colonial ante litteram, may be traced among Coptic and Syriac polemicists as well, a subject of research that would benefit from further analysis

Vulcan and anomalous displacement of Mercury's perihelion

In this paper, I re-examine the question of a possible explanation of the anomalous advance of Mercury's perihelion by the existence of the hypothetical planet Vulcan proposed by Le Verrier, whose orbit would be located inside the orbit of Mercury. My calculations are focused on the optimization of the orbital parameters of Vulcan in order to explain precisely the anomalous advance of Mercury's perihelion. To reach this goal, I used recent experimental results concerning the observations of the intra-mercurian zone. My calculations establish the direct relation of the anomalous advance of Mercury's perihelion with the mass of Vulcan and its distance to Mercury.Comment: 8 pages, 1 figure, 4 tables, 26 reference

Regional Migration Governance in the Americas: The Los Angeles Declaration on Protection and Migration\u27s Challenges and Opportunities

As the LA Declaration enters a new phase of maturation, it is imperative for the hemisphere to intensify efforts to overcome coordination and communication challenges among countries and levels of government. Addressing existing barriers, such as securing sustainable funding among others, is essential for countries and agencies to tackle specific migration challenges effectively. Additionally, regional policymakers must prioritize investments in migration to achieve broader societal objectives in the medium and long termhttps://digitalcommons.fiu.edu/jgi_research/1053/thumbnail.jp

Venezuelan Migration Crisis: Medium and Long-Term Impacts

The recent debate on Venezuela has primarily focused on the promotion of a political transition to reestablish a functioning democracy, respect for human rights, and restore a viable economy. However, the discussion and resulting actions should also focus on the need to address the medium to long term regional effects of the Venezuelan migration crisis. The human dimensions of the country’s protracted political, economic, and humanitarian crisis have been daunting, with 4.5 million Venezuelan migrants and refugees having fled their homeland between 2015 and 2019. This massive exodus is having the greatest impact on Latin American and Caribbean countries. The burden appears likely to intensify, moreover, as the number of displaced Venezuelans is projected to reach 6.5 million Venezuelans by the end of 2020. This study focuses on how the exodus will impact the economic, social, security, and political standing of countries with the highest concentration of Venezuelan migrants—namely Argentina, Brazil, Chile, Colombia, Ecuador, and Peru.https://digitalcommons.fiu.edu/jgi_research/1002/thumbnail.jp

Environmental Explanations of Central American Migration: Challenges and Policy Recommendations

In this report, the authors argue that when countries and relevant stakeholders do not prioritize disaster preparedness and foster community resilience, extreme climate events can deplete people’s material and socioeconomic well-being. This results in internal displacement as people seek economic opportunities and social protection, which may exacerbate conflict and social tension in the cities they move to. Ultimately, this helps explain one unexamined consideration driving migration to the United States from the Northern Triangle countries.https://digitalcommons.fiu.edu/jgi_research/1038/thumbnail.jp

Characteristics of partially filled Helmholtz resonators

In this work we have developed a technique for the measurement of the resonance curve of Helmholtz resonators as a function of filling with beads and sands of different sizes, and water as the reference. Our measurements allowed us to observe very different behaviors of resonance frequencies and resonance half-widths as a function of the size of the sand grains and the beads. By comparing results for beads and water we were able to prove that the sound penetrates the interstitial space between the beads. This was confirmed by measurements of the resonance properties in resonators filled with spherical beads whose experimentally determined filling factor is close to the random filling factor of about 0.54. The similar behavior of the frequency and half-width of resonance of sand-filled resonators of three different sizes allowed us to suggest that sound penetrates the sand in the same way as it does the beads.Comment: 10 pages, one column, 9 figures, regular pape
