Convergence and preservation of cyclicity
No full textWe prove that the set of cyclic (respectively, non-cyclic) functions in Dirichlet type spaces Dα is not closed in the topology induced by the norm. We also show that some additional conditions on a convergent sequence of cyclic functions {fn} force cyclicity of the limit f. We show counterexamples satisfying all but one of these conditions. Then we find precise estimates for the distance between the corresponding optimal polynomial approximants of each degree d and control its blow up as the choice of f moves within Dα.Fil: Aguilera Aguilera, Alejandra Patricia.

Effect of Oil Production on the Price of Oil
No full textThe objective of this paper is to investigate the effect of oil production on the price of oil considering particularly the case of unconventional (tight and shale) reservoirs.
Five years ago, at LACPEC 2014 in Maracaibo, Venezuela, we presented an original paper and a methodology to investigate the price of oil. We stated in that paper that "with the vast global oil resource base and significant technological advances being implemented by the industry, oil prices could decrease in the future" (Aguilera and Aguilera, 2014). Given the good comparison between our 2014 LACPEC study and the actual oil pricing during the last 5 years, we use the same methodology for investigating possible ranges of oil prices in the future.
Our results stem from a successful match, using a Variable Shape Distribution (VSD) model, of the small and large variations of oil prices since 1861. Results are good, with a coefficient of determination (R2) larger than 0.98. We also match successfully oil consumption rates from 1861 to 2019 using a Global Energy Market (GEM) Model. The combination of the VSD and GEM, and our investigation on availability of oil resources, lead to the conclusion that our 2014 statement at LACPEC in Maracaibo remains current: "with the vast global oil resource base and the significant technological advances being implemented by the industry, oil prices could decrease in the future". Our methodology further indicates that, barring an unforeseen global disruptive event, oil prices will remain depressed for the foreseeable future. This supports the findings of Aguilera and Radetzki (2015) who in their book, The Price of Oil, forecast oil prices between 60 by 2035. This contrasts with the work of authoritative energy forecasting agencies who project rising prices in the coming decades. Also, as opposed to some oil companies, particularly some of the European organizations, that see the peak oil demand coming soon enough, e.g. the mid-2020s, our research indicates that it is unlikely that oil demand will peak in the coming decades.
The uniqueness of our forecasting methods for the oil price and global oil consumption is that our methods have remained unchanged since their creation (Aguilera and Aguilera, 2007) and yet they continue to generate reasonable results. This contrasts with methods of other organizations and commentators that change their forecasts repeatedly
Leveraging social network analysis with topic models and the Semantic Web
No full textSocial Network Analysis (SNA) and Web Mining (WM) techniques are being applied to study the structures of social networks in order to manage their dynamics and predict their evolution. This paper describes how we used Semantically-Interlinked Online Communities (SIOC) ontology to represent the (latent) semantic relationships between the members of a large community forum (about 2,500), Plexilandia. We extended SIOC, taking advantage of topic-based text mining and developed data mining algorithms that used our SIOC extensions to provide a better understanding of the social dynamics of the members of the Plexilandia community. This new understanding helped us to detect and discover the key members of Plexilandia successfully

No full textVariations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
