• Echoes across a half century: Ray Bradbury's Leviathan '99

      Nichols, Philip; Morrissey, Thomas J; De Los Santos, Oscar (Fine Tooth Press, 2007-08-21)
      What happens when an SF writer branches out of the genre and collides with a nineteenth-century precursor? When Ray Bradbury was commissioned, fifty years ago, to write a screenplay based on Moby Dick, the power of that collision created reverberations through the remainder of Bradbury's career. His experience in crafting a streamlined narrative from Melville's discursive novel was to affect his approach to dramatization of his own stories. His experience in Ireland working on the screenplay would provide material for countless Irish stories, plays and a novel (Green Shadows, White Whale). Bradbury's fascination with Melville saw his continued development, from the early 1960s, of Leviathan '99. Glibly describable as “Moby-Dick in space”, Leviathan ‘99 has appeared as a radio play, stage play, opera, and finally a novel, a late-career return to the genre which brought Bradbury early success. This paper gives an account of Bradbury's original radio version of Leviathan 99 (BBC, 1968). It relates the play's development to Bradbury's experiences working with John Huston on Moby Dick in the 1950s, traces some of the ripples from that experience through other of Bradbury's work, and characterizes the intertextuality of Leviathan ‘99 as typical of Bradbury’s approach.

    • Effect of exercise training and dopamine agonists in patients with uremic restless legs syndrome: A six-month randomized, partially double-blind, placebo-controlled comparative study

      Giannaki, CD; Sakkas, GK; Karatzaferi, C; Hadjigeorgiou, GM; Lavdas, E; Kyriakides, T; Koutedakis, Y; Stefanidis, I; Department of Nephrology, School of Medicine, University of Thessaly, Larissa, Greece. gsakkas@med.uth.gr. (Springer Science and Business Media LLC, 2013-09-11)
      Background: Restless Legs Syndrome is very common in hemodialysis patients however there are no comparative studies assessing the effectiveness of a non-pharmacological treatment to a classical treatment on parameters related to syndromes' severity and quality of life. Methods. In this randomized, partially double blind, placebo controlled trial, thirty two hemodialysis patients with restless legs syndrome were randomly assigned into three groups: 1) the exercise training group (N = 16), 2) the dopamine agonists group (ropinirole 0.25 mg/d) (N = 8) and 3) the placebo group (N = 8). The intervention programs lasted 6 months. Restless Legs Syndrome severity was assessed using the international severity scale, physical performance by a battery of tests, muscle size and composition by computed tomography, body composition by Dual Energy X Ray Absorptiometry, while depression score, sleep quality, daily sleepiness and quality of life were assessed through questionnaires. Results: Exercise training and dopamine agonists were effective in reducing syndrome's symptoms by 46% (P = 0.009) and 54% (P = 0.001) respectively. Within group changes revealed that both approaches significantly improved quality of life (P < 0.05), however, only the dopamine agonists significantly improved sleep quality (P = 0.009). Within group changes showed a tendency for lean body mass improvements with dopamine agonists, this reached statistical significance only with the exercise training (P = 0.014), which also reduced fat infiltration in muscles (P = 0.044) and improved physical performance (P > 0.05) in various tests. Between group changes detect significant improvements with both exercise and dopamine agonists in depression score (P = 0.003), while only the dopamine agonist treatment was able to significantly improve sleep quality, compared to exercise and placebo (P = 0.016). Conclusions: A 6-month exercise training regime was as effective as a 6-month low dosage dopamine agonist treatment in reducing restless legs syndrome symptoms and improving depression score in uremic patients. Further research is needed in order to show whether a combination treatment could be more beneficial for the amelioration of RLS. Trial registration.

    • The effect of pre-exercise ingestion of corinthian currant on endurance performance and blood redox status

      Deli, CK; Poulios, A; Georgakouli, K; Papanikolaou, K; Papoutsis, A; Selemekou, M; Karathanos, VT; Draganidis, D; Tsiokanos, A; Koutedakis, Y; et al. (Informa UK Limited, 2018-02-22)
      © 2018, © 2018 Informa UK Limited, trading as Taylor & Francis Group. The present study investigated the effect of Corinthian currant pre-exercise supplementation on metabolism, performance and blood redox status during, and after prolonged exercise. Eleven healthy participants (21-45y) performed a 90-min constant-intensity (60–70% VO2max) submaximal-trial, plus a time-trial (TT) to exhaustion (95% VO2max) after consuming an isocaloric (1.5g CHO/kg BM) amount of randomly assigned Corinthian currant or glucose-drink, or water (control). Blood was drawn at baseline, pre-exercise, 30min, 60min, 90min of submaximal-trial, post-TT, and 1h post-TT. Post-ingestion blood glucose (GLU) under Corinthian currant was higher compared with water, and similar compared with glucose-drink throughout the study. Respiratory quotient under Corinthian currant was similar with glucose-drink and higher than water throughout the submaximal trial. Accordingly, higher CHO and lower fat oxidation were observed under Corinthian currant compared with water. The TT performance was similar between Corinthian currant, glucose-drink and water. Redox status were similar under all three conditions. Reduced glutathione (GSH) declined while total antioxidant capacity (TAC) and uric acid increased during exercise. GSH and TAC returned to baseline, while uric acid remained increased the following 1h. Corinthian currant, although did not alter exercise-mediated redox status changes and performance, was equally effective to a glucose-drink in maintaining GLU levels during prolonged cycling.
    • The effects of low and high glycemic index foods on exercise performance and beta-endorphin responses

      Jamurtas, AZ; Tofas, T; Fatouros, I; Nikolaidis, MG; Paschalis, V; Yfanti, C; Raptis, S; Koutedakis, Y; University of Thessaly, Department of Physical Education and Sport Science, Karies, 42100, Trikala, Greece. ajamurt@pe.uth.gr. (Springer Science and Business Media LLC, 2011-10-20)
      Τhe aim of this study was to examine the effects of the consumption of foods of various glycemic index values on performance, β-endorphin levels and substrate (fat and carbohydrate) utilization during prolonged exercise. Eight untrained healthy males underwent, in a randomized counterbalanced design, three experimental conditions under which they received carbohydrates (1.5 gr. kg-1 of body weight) of low glycemic index (LGI), high glycemic index (HGI) or placebo. Food was administered 30 min prior to exercise. Subjects cycled for 60 min at an intensity corresponding to 65% of VO2max, which was increased to 90% of VO2max, then they cycled until exhaustion and the time to exhaustion was recorded. Blood was collected prior to food consumption, 15 min prior to exercise, 0, 20, 40, and 60 min into exercise as well as at exhaustion. Blood was analyzed for β-endorphin, glucose, insulin, and lactate. The mean time to exhaustion did not differ between the three conditions (LGI = 3.2 ± 0.9 min; HGI = 2.9 ± 0.9 min; placebo = 2.7 ± 0.7 min). There was a significant interaction in glucose and insulin response (P < 0.05) with HGI exhibiting higher values before exercise. β-endorphin increased significantly (P < 0.05) at the end of exercise without, however, a significant interaction between the three conditions. Rate of perceived exertion, heart rate, ventilation, lactate, respiratory quotient and substrate oxidation rate did not differ between the three conditions. The present study indicates that ingestion of foods of different glycemic index 30 min prior to one hour cycling exercise does not result in significant changes in exercise performance, β-endorphin levels as well as carbohydrate and fat oxidation during exercise. © 2011 Jamurtas et al; licensee BioMed Central Ltd.
    • The effects of pre-exercise corinthian currants supplementation on antioxidant responses

      Jamurtas, Athanasios Z; Deli, Chariklia K; Fatouros, Ioannis G; Selemekou, Maria; Papoutsis, Alexandros; Koutedakis, Yiannis; Karathanos, Vaios (Ovid Technologies (Wolters Kluwer Health), 2016-05)
      Τhe use of nutritional supplements before and during a sporting event, especially of a prolonged nature, is very common among competitors and routinely advised by exercise professionals. Corinthian currants have a high carbohydrate content making them a potentially ideal carbohydrate source for prolonged exercise. However, their effectiveness as an ergogenic aid has never been studied.
    • The effects of training with high-speed interval running on muscle performance are modulated by slope

      Theofilidis, George; Bogdanis, Gregory C; Stavropoulos-Kalinoglou, Antonios; Krase, Argyro A; Tsatalas, Themistoklis; Shum, Gary; Sakkas, Giorgos K; Koutedakis, Yiannis; Karatzaferi, Christina; Experimental Physiology & Therapeutic Exercise Laboratory, Muscle Physiology and Mechanics Group, CREHP, School of Physical Education Sports Science and Nutrition, University of Thessaly, Trikala, Greece. (Wiley, 2021-01-05)
      We examined changes in selected muscle performance parameters after 8 weeks of interval training using two opposite running inclinations. We hypothesized that the uphill training will affect endurance muscle performance outcomes, whereas the downhill training will affect power muscle performance outcomes. Fourteen physically active volunteers were randomly assigned into either the Uphill group (UG; n = 7; uphill interval running at +10% incline) or the Downhill group (DG; n = 7; downhill interval running at -10% incline) and completed 16 training sessions. Each session consisted of ten 30 s treadmill runs at 90% of maximum aerobic speed (MAS) with a work to rest ratio of 1:2. Vertical jump performance, isometric (MVC) and isokinetic torque of knee extensors and flexors, and fatigue of knee extensors were evaluated pre and post-training. Moreover, body composition (via bioimpedance) and vastus lateralis muscle architecture (via ultrasonography) were assessed pre and post-training. Relative lean tissue mass, relative fat mass, and squat jump (cm) significantly (p < .05) changed from baseline values by +4.5 ± 4.0%, -11.5 ± 9.6%, and +9.5 ± 11.7%, respectively, only in the DG. Similarly, DG improved absolute values of knee extension rate of torque development and impulse (p < .05), whereas knee flexion peak torque angle significantly decreased in both groups (p < .05). On the other hand, the UG increased the number of repetitions achieved during the fatigue protocol and total work by 21.2 ± 32.6% and 13.8 ± 21.2%, respectively (p < .05). No differences were found between groups in muscle architecture. Introducing variations in slope during HIIT could be used to induce specific improvements toward muscle endurance or power performance characteristics.
    • Electric Cherry Blossom

      Harris, Simon J. (Sarah Wiseman Gallery, 2018-03-03)
      'Electric Cherry Blossom' was inspired by a recent visit Simon made to the Van Gogh Museum in Amsterdam. He is in essence concerned with painting as an act in and of itself, exploring the interplay between the recognisable and abstracted expression. His influences are varied; he cites Van Gogh and Japanese printmaking; Vermeer and Rembrandt; Cinematography. These influences all reference developments in our understanding and preoccupation with pictorial space, and how abstract, apparently empty spaces can carry so much more weight in a painting or an image than we might first realise.
    • Embedding art as a research methodology within educational processes

      Prior, Ross (INTED 2020, 2020-03-02)
      The focus of this position paper outlines and explores the way art, as a research methodology, can be understood and used more fully within the context of education. The paper demonstrates that in art-based research and in the teaching leading to it, art is both the object of investigation and the method of inquiry. Art-based research involves deep reflection on the interplay between mental motivations and physical ones that are present through contact with the medium (artform). The world-wide growing appreciation of using art as research within higher education is gaining considerable momentum with the explicit promotion of having the most relevance to artist-educator-researchers and resisting the dominance of social sciences within education which has not adequately served artistic inquiry. Aim and Objective: The aim of this paper is to propose that, at the centre of art as research, the artist-educator-researcher can bring together the tensions evident in higher education. The principle objective of the paper is to introduce a new concept by the author acknowledging the threefold primacy of art in research and education: art as the topic, process and outcome of research. Art as Methodology: In art-based research we can ask what the object or creative expression reveals about itself and what role the artist plays. Rather than providing an accompanying narrative by the artist giving a self-referential, one-sided emoted account of what the artist experienced or intended, art-based research offers a more complete research approach that recognizes the artistic objects of art as ‘full participants’ in the process. The artefact (e.g. piece of music, painting, dance) and the active interplay between the artwork, the process and the artist (as artist-educator-researcher) define the methodology known as 'art as research' or 'art-based research'. Findings and Conclusion: Examples of this interplay will be presented in sharing the multiple outcomes of this method of researching within education. The results of these exemplar approaches reveal that research questions and findings arise in and through practice. Processes, if studied, reveal a great depth of knowledge. Art-based inquiry, therefore, includes multiple ways of knowing, including affective, sensory, creative, observational and intuitional, as well as the use of experimentation, risk-taking, discovery and meaning-making through the process of making art. The findings from the exemplar approaches presented also demonstrate that artwork of any type can be art itself, with responses drawn from poetry, dance, performance and so on. There is tremendous richness and endless possibilities for a researcher in these types of investigations, and therefore the potential for learning and teaching is immense. In conclusion, this paper finds that scientific and social scientific approaches are not fully useful to artists. Rather artists can make use of art as a research methodology to investigate their own practices and outcomes seeing art as the topic, process and outcome of research.
    • Embracing openness: music technology pedagogy and curricula after the decline of the studio

    • Embryonic

      Bird-Jones, Christine (2006)
      “Embryonic” was the first of a series of collaborative works with video artist Heald. The result was a collaborative installation utilising translucency and transparency in both film and kiln formed glass. Two years ago both artists identified a common interest and focus in each other’s work concerning light and movement. Heald was developing projections of her film works onto objects; Bird-Jones was experimenting with moving image in glass. The ensuing collaboration set out to explore how joining both media could enhance the effect of the ephemeral qualities common to both film and glass. These qualities were taken to be: translucency and transparency; and the static quality of glass created from liquid and the dynamic form of video film based on static script or code. Several glass samples were produced and experimented with by the collaborators in the studio. They experimented with Bullseye and Float glass, tack fusing crushed base glass seeking an appropriate and evocative surface to receive the projected film. Material and visual research was conducted concerning scale, size, fixings and juxtaposition of material.
    • The end of racism and the last ideology: The Cosby Show’s Fukuyaman neo-liberal children

      Geal, Robert; Schober, Adrian; Olson, Debbie (Routledge, 2018-07-03)
      Both popular and academic discourses on The Cosby Show have focused on the eponymous family’s post-racial representation. Challenging historically negative television and film depictions of the African American as an exotic and/or savage ‘Other’, the program’s upper middle-class professional family presented 1980s white America with an image of blackness that had been fully assimilated into hegemonic culture. Academic analyses of this acculturation have considered both the impact of this ostensibly positive depiction of the black family for white audiences, and the subtle traces of African American social and cultural experiences which appealed to black audiences. Discourses about the show’s children have also positioned the characters’ relationships with their white contemporaries within a post-racial context, so that they undergo the same kind of bildungsroman angst and trajectory as other, whiter, 1980s coming-of-age narratives, without any particular experience rooted in racial difference. This essay situates the show’s children within a wider post-racial context that dominated American political and social culture during the period 1984-1992 when the show ran. This was the era of triumphant Reaganomics, punctuated by the fall of the Berlin Wall, and bookended with Francis Fukuyama’s influential panegyric to neo-liberalism’s victory over every other possible form of ideology, The End of History and the Last Man. The Cosby Show’s professional American nuclear family is post-racial not only because of the gradual impact of socio-cultural and legal developments emanating from the Civil Rights movement. Even more fundamentally, the enormous popularity of the show’s Huxtable family, amongst both black and white audiences, in America and beyond, encapsulates Fukuyama’s color-blind ideological model – a celebration of hard work and cooperation leading to the enjoyable consumption of plenty, with any inconvenient impediments to this vision, such as race, class, gender or sexuality, overcome through virtuous labor and consumption. The show’s children, inheritors of the End of History, are the central drivers and beneficiaries of this process.
    • The Ends of Art (curated by Euripides Altintzoglou)

      Altintzoglou, Euripides; Altintzoglou, Euripides; Abernethy, Jim; Bracey, Andrew; Cornford & Cross; Kelland, Dean; Kossoff, Adam; Timberlake, John; Payne, Alistair; Dalgleish, Mat (2013-07-05)
      From Marius de Zayas to David Rabinowitch Richard Huelsenbeck and, and from Arthur Danto to David Kuspit art is declared dead every time it goes through a critical stage in its course of development. Post-modern stylistic plurality posed as the end of art history but recently relational aesthetics placed Pluralism under dispute and in doing so signaled the dawn of a new era. Instead of joining conservative historians in a post-apocalyptic religiosity about the loss of all that was great in art we need to turn to critical self-reflective strategies that echo the spirit of conceptualism. The intention of this group of works is not to simply demonstrate ways by which there can be art after the ‘end of art’ and thus to seek for means to satisfy Arthur Danto’s uncertainty about the future of art after Plurality by sustaining a purist approach to art history. Rather, each work included in the Ends of Art deals solely with the nature of a given discipline through another and, thus investigates the potential for an even more radical and thorough process of examination of the changing nature of art through interdisciplinarity; expanding the field of each discipline is the methodology of this exhibition, not the aim. At the core of this methodology is the intention to eradicate the last remaining traces of humanism in art history: the dissolution of distinct art disciplines for the means of theoretical analysis.
    • Enhanced erythrocyte antioxidant status following an 8-week aerobic exercise training program in heavy drinkers

      © 2017 Elsevier Inc. Alcohol-induced oxidative stress is involved in the development and progression of various pathological conditions and diseases. On the other hand, exercise training has been shown to improve redox status, thus attenuating oxidative stress-associated disease processes. The purpose of the present study was to evaluate the effect of an exercise training program that has been previously reported to decrease alcohol consumption on blood redox status in heavy drinkers. In a non-randomized within-subject design, 11 sedentary, heavily drinking men (age: 30.3 ± 3.5 years; BMI: 28.4 ± 0.86 kg/m2) participated first in a control condition for 4 weeks, and then in an intervention where they completed an 8-week supervised aerobic training program of moderate intensity (50–60% of the heart rate reserve). Blood samples were collected in the control condition (pre-, post-control) as well as before, during (week 4 of the training program), and after intervention (week 8 of the training program). Samples were analyzed for total antioxidant capacity (TAC), thiobarbituric acid reactive substances (TBARS), protein carbonyls (PC), uric acid (UA), bilirubin, reduced glutathione (GSH), and catalase activity. No significant change in indices of redox status in the pre- and post-control was observed. Catalase activity increased (p < 0.05) after 8 weeks of intervention compared to week 4. GSH increased (p < 0.05) after 8 weeks of intervention compared to the control condition and to week 4 of intervention. TAC, UA, bilirubin, TBARS, and PC did not significantly change at any time point. Moreover, concentrations of GSH, TBARS, and catalase activity negatively correlated with alcohol consumption. In conclusion, an 8-week aerobic training program enhanced erythrocyte antioxidant status in heavy drinkers, indicating that aerobic training may attenuate pathological processes caused by alcohol-induced oxidative stress.

      Alcohol-induced oxidative stress is involved in the development and progression of various pathological conditions and diseases whereas exercise training has been shown to improve redox status, thus attenuating oxidative stress-associated disease processes. PURPOSE: to evaluate the effect of an exercise training program on blood redox status in heavy drinkers. METHODS: Eleven sedentary, heavy drinking men participated in an intervention where they completed an 8-week supervised aerobic training program of moderate intensity. Blood samples were collected before, during (week 4) and after intervention and analyzed for total antioxidant capacity (TAC), thiobarbituric acid reactive substances (TBARS), protein carbonyls (PC), uric acid (UA), bilirubin, reduced glutathione (GSH) and catalase activity. RESULTS: Catalase activity increased (p<0.05) after 8 weeks (340.7+13.3 U mg/Hb) of intervention compared to week 4 (299.5+18.7 U mg/Hb). GSH increased (p<0.05) after 8 weeks of intervention (1.22+0.16 μmol/g Hb) compared to the control condition (1.11 + 0.17 μmol/g Hb) and to week 4 (1.11 + 0.15 μmol/g Hb ). TAC, UA, bilirubin, TBARS and PC did not significantly change at any time point. CONCLUSION: An 8-week aerobic training program enhanced erythrocyte antioxidant status in heavy drinkers, indicating that aerobic training may attenuate pathological processes caused by alcohol-induced oxidative stress.
    • Enhancing virtual reality with artificial life: Reconstructing a flooded European Mesolithic landscape

      Ch'ng, Eugene; Stone, Robert J. (MIT Press, 2006)
      The fusion of Virtual Reality and Artificial Life technologies has opened up a valuable and effective technique for research in the field of dynamic archaeological reconstruction. This paper describes early evaluations of simulated vegetation and environmental models using decentralized Artificial Life entities. The results demonstrate a strong feasibility for the application of integrated VR and Artificial Life in solving a 10,000 year old mystery shrouding a submerged landscape in the Southern North Sea, off the east coast of the United Kingdom. Three experimental scenarios with dynamic, “artificial” vegetation are observed to grow, reproduce, and react to virtual environmental parameters in a way that mimics their physical counterparts. Through further experimentation and refinement of the Artificial Life rules, plus the integration of additional knowledge from subject matter experts in related scientific fields, a credible reconstruction of the ancient and, today, inaccessible landscape may be within our reach.
