Big Data, Big Libraries, Big Problems?: the 2014 LibTech Anti-talk?
Get PDFThe desire to create automatons is a familiar theme in human history, and during the age of the Enlightenment mechanical automatons became not only an “emblem of the cosmos”, but a symbol of man’s confidence that he would unlock nature’s greatest mysteries and fully harness her power. And yet only a century later, automatons had begun to represent human repression and servitude, a theme later picked up by writers of science fiction. Man’s confidence undeterred, the endgame of the modern scientific and technological mindset, or MSTM, seems to be increasingly coming into view with the rise of “information technology” in general and “Big data” in particular. Along with those who wield them, these can be seen as functioning together as a “mechanical muse” of sorts – surprisingly alluring – and, like a physical automaton can serve as a symbol – a microcosm – of what the MSTM sees (at the very least in practice) as the cosmic machine, our “final frontier”. And yet, individuals who unreflectively participate in these things – giving themselves over to them and seeking the powers afforded by the technology apart from technology’s rightful purposes – in fact yield to the same pragmatism and reductionism those wielding them are captive to. Thus, they ultimately nullify themselves philosophically, politically, and economically – their value increasingly being only the data concerning their persons, and its perceived usefulness. Likewise libraries, the time-honored place of, and symbol for, the intellectual flowering of the individual, will, insofar as they spurn the classical liberal arts (with the idea that things are intrinsically good, and in the case of humans, special as well) in favor of the alluring embrace of MSTM-driven “information technology” and Big data - unwittingly contribute to their irrelevance and demise as they find themselves increasingly less needed, valued, wanted. Likewise for the liberal arts as a whole, and in fact history itself, if the acid of a “science” untethered from what is, in fact, good (intrinsically), continues to gain strengt

Adam Nicolson's 2023 Book How to Be: Life Lessons from the Early Greeks, and Walter J. Ong's Thought
No full textSee the above abstract.In my deeply retrospective 4,215-word review essay "Adam Nicolson's 2023 Book How to Be: Life Lessons from the Early Greeks, and Walter J. Ong's Thought," I selectively highlight the prolific English author Adam Nicolson's 2023 book How to Be: Life Lessons from the Early Greeks (Farrar, Straus and Giroux). I situate his work in the larger conceptual framework of the work of the American Jesuit Renaissance specialist and cultural historian and pioneering media ecology theorist Walter J. Ong (1912-2003; Ph.D. in English, Harvard University, 1955) -- and the extensive related work of numerous other scholars, including the philosopher Eric Voegelin and the classicist Eric A.

Effects of surface-modified 3D printed titanium bone implants on human macrophages
No full textTitanium orthopaedic biomaterials to replace degenerated joint surface, improve bone regeneration and fixation are studied and used worldwide. However, not always biomaterial implantation is successful, and the main causes of implant failure remain implant associated infections (IAI) and poor osseointegration. In the recent years, additive manufacturing and titanium surface modification have been extensively researched in order to develop bone implants able to enhance bone formation at bone/material interface while reducing the risk of microbial adhesion. New bone formation at the implant site is an inflammation-driven process, since the implantation of a biomaterial in the human body is always followed by an immune response. Among the inflammatory cells involved in the inflammation stage following initial hemostasis after surgery, macrophages play a crucial role in regulating subsequent bone formation and remodelling secreting a wide range of factors. Therefore, in this study, human macrophage response to 3D printed Ti-6Al-4V surfaces was investigated. Ti-6Al-implants were modified by plasma electrolytic oxidation (PEO), during which an oxide layer containing electrolyte components were generated on implant surfaces. In order to generate an antimicrobial coating, silver nano-particles (Ag NPs) were also incorporated into the surface. Surface morphology and chemical composition were analysed by SEM. Human macrophages were cultured in the presence of SLM implants in a transwell culture or directly on the surface for 4 days. Macrophage morphology and viability were assessed with scanning electron microscopy (SEM) and fluorescence microscopy. Cell secreted factors were analysed performing an ELISA assay while gene expression analysis was performed using qPCR. Human mesenchymal stem cell (hMSC) response in terms of morphology and viability was also evaluated after 4 days of culture. PEO modification on SLM surfaces resulted in an additional TiO2 layer containing electrolyte components (Ca, P and Ag) and interconnected porosity. The ion release from SLM surfaces did not have an effect on human macrophage polarisation, while when cells where cultured directly on the implants, they secreted and expressed different amounts of pro- and anti-inflammatory factors. SLM NT (not PEO-treated) surfaces up-regulated macrophage pro-inflammatory cytokines compared to SLM PEO surfaces. However, cells cultured on SLM NT up-regulated also anti-inflammatory factors. SLM surfaces containing Ag NPs were cytotoxic for human macrophages but not for hMSCs. In general, both SLM NT and SLM PEO surfaces expressed anti-inflammatory and tissue repair-related macrophage factors, suggesting that either implant geometry achieved by 3D printing and surface biofunctionalization may have beneficial impact on promoting macrophage anti-inflammatory secretion and subsequent osteogenesis around the implant
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“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
