Velocity: change / at speed / everywhere
No full textThe rushing up of the Earth from below as we leap into the unknown is a strong pervasive force. The comings and goings of objects, the rhizomatic fever of life - of memories and of perception - is the stuff of both nature and the machine but also the stuff of change - of a compelling need to move forward, at pace. Since the millennium we have been moving away in linear time from the trauma of the 20th century, history accumulating behind us as we hurtle towards an undefined future. Yet there also seems to be a reductive velocity at work, the future appears to be expanding only in our mind’s eye - in the stories we tell ourselves, in the frames of the cinematic moment and the pixels of our most fantastic dreaming. If we stand still long enough the hyper-reality becomes apparent. Information is expanding at an exponential rate – images, sound and text – authoring a new present-future space of mobility, of interconnectedness and most of all of rapid accelerating change. Equal parts chaos and perfection – of truth and of fiction - a dark and light exposure.
It is the making of us, this velocity of things. It is both our return to Earth and our mastery of its physics. Our identity and our collective history is fast becoming a vast data repository of machine vision - a rapid prototyping of our future selves. Financial transactions, personal communications, intimate moments exist inside this simulation of machine speed. Artificial intelligence observes, correlates, measures and makes split second decisions on our behalf. Notions of surveillance, fears for our privacy, the dilution of our identity and the voyeuristic connotations of relational databases make up the machine’s vision of us and our world. Can we keep apace of these algorithmic patterns? Can we author new vistas, new dreamscapes, new directions?
Meanwhile, history keeps up a steady persistent pace: the image loops, the cogs turn, the velocity increases, and the hyper-real maintains its seductive play
Resistance: disrupt the information flow
No full textIf art is a political act, then media art is a technologically enabled one. How can screen based media embody the notion of resistance? What is it that we see when we peer out of the virtual panopticon of our contemporary cities, shopping malls, office blocks and vessels of transportation with our networked devices of communication?
Indeed by making art we are conducting an act of resistance. We are subverting accepted norms, we are stepping outside of the media stream – or directly in front of it – and making a calculated statement. Through media interventions we can point toward alternative pathways, expose bias and stand apart from the common binary politics of our times. As Graham Harman notes, “As philosophers, we're not supposed to be swept along with the Zeitgeist, we’re supposed to be resisting it.”
We resist political rhetoric by asking questions of language, of history and of context. We resist surveillance by pointing the camera back at the watchers. We resist the recurring bile of racism, sexism and bigotry by subverting stereotypes by creating new forms of beauty and a more interconnected sense of identity. We resist the predatory nature of capital and the upward linearity of growth and accumulation by challenging notions of value and currency with alternative definitions of wealth and new expressions of personal freedom.
For Screenrab7 all forms of resistance will be considered: the politics of resistance, the physics of resistance, the messiness of resistance, and the urgency of resistance. In this age of contradiction – and as Bruce Sterling has observed, of “favela chic and gothic high-tech” – it is the duality of our relationship to the forces of order and control that is under examination here.
We resist, not as some might have it – to impede or to destroy the status quo – indeed, that would be too obvious, too easy, and too predictable. Resistance through art making, through creative expression, is subtler and more nuanced than that. The act of resistance in art, as in life, is to demand a more complex, empathetic and interconnected human experience
Compendium of anatomical variants: a unique variation of the sciatic nerve
No full textThe normal course of the sciatic nerve out of the
pelvis is through the greater sciatic foramen, below
the inferior border of piriformis muscle and descends
between the greater trochanter and the ischial
tuberosity (Williams, 1995). There is evidence for
anatomical variations of the course or level of
division of the sciatic nerve (Pokorny et al., 2006).
Variations of the anatomy of the sciatic nerve may
be responsible for complications related to total hip
arthroplasties
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
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
