Varianti d’autore: Invenzioni su una voce di Bruno Maderna
Antonio Rodà
Musica e Tecnologia , 2009,
Abstract: Author’s variants: Invenzioni su una voce by Bruno Maderna The analogue audio documents, containing the Electronic works of the second half of the XX Century, are often the result of a transmission process whose phe-nomenology, although it presents some peculiarities, shows analogies with the tex-tual tradition. In this context, Dimensioni II. Invenzione su una voce by Bruno Mad-erna is an interesting case study: the more than twenty reviewed sources, which are different for duration, content, and recording format; the existence of at least five author’s variants; the many relations among the Helm’s text, the Berberian’s per-formance, the electronic elaborations, and the tape editing process require edition criteria able to render the tradition of the work in its complex articulation. This paper gives a detailed analysis of the audio sources of Invenzione su una voce, based on a deep knowledge of the electronic “writing system”, by mean of which the work has been generated.
The Safeguard of Audio Collections: A Computer Science Based Approach to Quality Control—The Case of the Sound Archive of the Arena di Verona
Federica Bressan,Antonio Rodà,Sergio Canazza,Federico Fontana,Roberta Bertani
Advances in Multimedia , 2013, DOI: 10.1155/2013/276354
Abstract: In the field of multimedia, very little attention is given to the activities involved in the preservation of audio documents. At the same time, more and more archives storing audio and video documents face the problem of obsolescing and degrading media, which could largely benefit from the instruments and the methodologies of research in multimedia. This paper presents the methodology and the results of the Italian project REVIVAL, aimed at the development of a hardware/software platform to support the active preservation of the audio collection of the Fondazione Arena di Verona, one of the finest in Europe for the operatic genre, with a special attention on protocols and tools for quality control. On the scientific side, the most significant objectives achieved by the project are (i) the setup of a working environment inside the archive, (ii) the knowledge transfer to the archival personnel, (iii) the realization of chemical analyses on magnetic tapes in collaboration with experts in the fields of materials science and chemistry, and (iv) the development of original open-source software tools. On the cultural side, the recovery, the safeguard, and the access to unique copies of unpublished live recordings of artists the calibre of Domingo and Pavarotti are of great musicological and economical value. 1. Introduction Considerable efforts have been spent on the preservation of sound archives over the past decades (see [1, 2] for an overview), and a variety of methodologies and best practices are currently made available by the international community (see [3–6]). The importance of audio recordings (speech and music) as documentary sources for disciplines such as linguistics, musicology, ethnomusicology, anthropology is fully recognized today. But, unlike other cultural materials such as books and paintings, the Life Expectancy (LE) of audiovisual documents is very short; that is, it can be measured in decades rather than in centuries. In addition, the problem of preservation of audio and video is increasingly overshadowed by the problems of the obsolescence of the technology used to access them [7]. In their experience with real-world archives, the authors found that an overall underestimation of the importance of quality control during the process of remediation (the process of transferring the acoustic information from a medium onto another medium) affects many digitization projects as well as their output. The main reason for this underestimation is that traditional actors of cultural institutions are unprepared against complex problems with a strong
On the Role of Auditory Feedback in Robot-Assisted Movement Training after Stroke: Review of the Literature
Giulio Rosati,Antonio Rodà,Federico Avanzini,Stefano Masiero
Computational Intelligence and Neuroscience , 2013, DOI: 10.1155/2013/586138
Abstract: The goal of this paper is to address a topic that is rarely investigated in the literature of technology-assisted motor rehabilitation, that is, the integration of auditory feedback in the rehabilitation device. After a brief introduction on rehabilitation robotics, the main concepts of auditory feedback are presented, together with relevant approaches, techniques, and technologies available in this domain. Current uses of auditory feedback in the context of technology-assisted rehabilitation are then reviewed. In particular, a comparative quantitative analysis over a large corpus of the recent literature suggests that the potential of auditory feedback in rehabilitation systems is currently and largely underexploited. Finally, several scenarios are proposed in which the use of auditory feedback may contribute to overcome some of the main limitations of current rehabilitation systems, in terms of user engagement, development of acute-phase and home rehabilitation devices, learning of more complex motor tasks, and improving activities of daily living. 1. Introduction Stroke is the leading cause of movement disability in the USA and Europe [1, 2]. In the EU, there are 200 to 300 stroke cases per 100,000 every year, and about 30% survive with major motor deficits [3]. These impressive numbers are increasing due to aging and lifestyle in developed countries. Improving the outcome of movement therapy after stroke is thus a major societal goal that received a lot of interest in the last decade from many researchers in the medical and engineering fields. After the acute phase, stroke patients require continuous medical care and rehabilitation treatment, the latter being usually delivered as both individual and group therapy. The rationale for doing motor rehabilitation is that the motor system is plastic following stroke and can be influenced by motor training [4]. Motor learning is a complex process and to date there is still a lack of knowledge on how the sensory motor system reorganizes in response to movement training [5]. Motor learning can be described as “a set of processes associated with practice or experience leading to relatively permanent changes in the capability for producing skilled action” [6]. Early after a stroke, the brain can undergo dramatic plastic changes [7, 8] that can be further enhanced by environmental stimulation. Animal studies have shown that an enriched poststroke recovery environment can induce structural plastic changes in the brain such as decreased infarct volume and increased dendritic branching, spine density, neurotrophic
Positive Psychology in the Elementary Classroom: The Influence of Strengths-Based Approaches on Children’s Self-Efficacy  [PDF]
Rod Galloway, Bronwyn Reynolds
Open Journal of Social Sciences (JSS) , 2015, DOI: 10.4236/jss.2015.39003

Despite the positive psychology movement being relatively young and academic research is still building in this area, there is growing confidence that identifying and developing children’s strengths could have profound long-term learning benefits. The intended outcome of this investigation is to contribute to the knowledge base about learning success when children’s emerging preferences, passions and abilities are recognized and developed. This paper explores the foundations of strengths-based approaches for education and presents the findings of a case study that suggests strengths-based approaches have a positive effect on student self-efficacy.

An Inclusive Re-Engagement with our Nonhuman Animal Kin: Considering Human Interrelationships with Nonhuman Animals
Rod Bennison
Animals , 2011, DOI: 10.3390/ani1010040
Abstract: As humans increasingly acknowledge the effects that they are having on the planet, there is a realisation implicit in these effects that human interrelationships with nature are actually arbitrated and expedited exploitatively. Understanding how the different discourses and histories through which the interrelationships with nature are mediated and actually told and then retold is fundamental to appreciating how humans may relate with nature less exploitatively and in ways that are more inclusionary, particularly with nonhuman animals. Humans perceive nature and individual nonhuman animals in various ways. This paper provides an investigation of how humans have socially constructed nature and their place as either within or outside of it. Such constructions are elaborated conceptually and through narrative. More pertinently, this paper examines how nature and nonhuman animals are perceived and placed within those narratives that humans construct from reality. It is stressed here that such constructions have, and may continue, to lead to a worsening of the effects that humans have on the planet if there is no acceptance or recognition that certain realities exist beyond the exploitative bounds of any human-inspired concept or narrative. This paper therefore provides the groundwork for the foundations of an ethic that is both socially and ecologically inclusive and is based on a soft realist approach.
The protamine family of sperm nuclear proteins

Genome Biology , 2007, DOI: 10.1186/gb-2007-8-9-227
Abstract: Salmonid fish can have as many as 15 closely related protamine genes per haploid genome, coding for as many as six different proteins [1]. Birds carry two virtually identical copies of the same gene per haploid genome [2], and only a single copy each of the genes for protamines P1 and P2 have been detected in mammals [3]. Even though it is likely that the protamine P2 gene derives from a duplication of the protamine P1 gene, the two proteins appear to be rapidly diverging in amino-acid sequence.The mammalian P1 and P2 genes contain a single intron (Figure 1), whereas the protamine genes from birds (chicken and quail) and salmonid fish are intronless. Detailed alignments of the cis-acting regulatory sequences have identified the presence of several consensus sequences. These include conserved cAMP-response elements, the TATA box, a CAP site, and a polyadenylation signal [4]. The two chicken protamine genes are clustered together within 6 kb of each other. The genes for human P1 and P2 are similarly co-located in a tight cluster on chromosome 16 at 16p13.2 [5]; this cluster also contains the gene for transition protein-2, which is also involved in chromosome condensation. A similarly arranged protamine cluster is found on chromosome 16 in the mouse [3]. In human, mouse, rat and bull the protamine cluster also contains an open reading frame that has been referred to as 'gene 4' [6] or 'protamine 3' [7]. The predicted aminoacid sequence for this protein, which would be approximately the same size as protamine P2, contains stretches of repeating glutamic and aspartic acid residues similar in number and distribution to the clusters of arginine and lysine residues found in the DNA-binding domains of protamines. This difference in composition (a high content of negatively charged amino acids compared with the high content of positively charged amino acids in protamines) suggests that the gene 4 protein, which is not likely to bind to and condense DNA, may instead bind to an

Abstract: Ausgangspunkt dieser Ver ffentlichung bildeten Tagungsbeitr ge und einige andere Texte vor allem nordamerikanischer Sozialwissenschaftler(innen), die in insgesamt 13 Kapiteln die Spannungen dokumentieren, die mit der Programmatik und Praxis angewandter Forschungsethik im Rahmen qualitativer Forschung einhergehen. Behandelt werden u.a. die Unterscheidung von Ethik und Moral, der Umgang mit Ethik-Kommissionen, Ethik im Forschungsprozess, Trends im Umgang mit Ethik in der Forschung, ethische Fragen bei der Antragstellung usw. Obwohl überwiegend nordamerikanische Beitragende (d.h. aus Kanada und den USA), k nnen deren Erfahrungen auch für Forschende anderer Nationalit ten interessant sein; eine Herausforderung bleibt in diesem Zusammenhang allerdings, dass wesentliche (kontinental-) europ ische Perspektiven nicht hinreichend berücksichtigt wurden. Gleichwohl werden ethische Fragen auf einem vergleichsweise anspruchsvollen Niveau behandelt. URN: urn:nbn:de:0114-fqs040214 This publication basically represents a collection of former conference papers and some other contributions mainly by North American social scientists on the dilemmas that qualitative researchers encounter when they submit research applications to research ethics committees. Collectively, the contributions demonstrate the tensions that exist in the policy and practice of applied research ethics in qualitative research. Thirteen chapters are included in this volume. They focus on the themes of: differentiating between ethics and morality; dealing with ethics committees and policies; research processes; research ethics trends; and, ethical issues when submitting research applications. The emphasis is on research policy in a North American context (Canada and the United States), but can be relevant for qualitative researchers in other parts of the world. One challenge to this context is that it does not capture the essence of some European perspectives, especially those from Continental Europe. However, it does raise the issue of ethics in qualitative research to a high level. URN: urn:nbn:de:0114-fqs040214 Esta publicación representa principalmente un conjunto de ponencias y otras contribuciones principalmente de científicos sociales de Norte América acerca de dilemas que los investigadores cualitativos encuentran cuando envían sus proyectos de investigación a los comités de ética. En conjunto, los artículos muestran las tensiones que existen que existen en la política y la práctica de la ética de la investigación aplicada en la investigación cualitativa. Trece capítulos forman el volumen. Se

Ghosts, God and the Problem of Dirty Hands
Nicholls, Rod
Ars Disputandi : the Online Journal for Philosophy of Religion , 2004,
Abstract: Under the rubric of the problem of dirty hands, Sartre and Camus explored a new approach to political necessity. Yet it has always been difficult to translate the powerful dramatic image of dirty hands into a coherent account of a philosophical problem. Many Anglo-American philosophers have argued that such an account is impossible. In Dawn, however, Elie Wiesel resolves the relevant paradoxes by imaginatively exploiting the religious consciousness of the novel ¢ € s main protagonist. Specifically, Wiesel adapts a traditional Jewish image of ghosts as a means of responding to the problem of dirty hands and then suggests a striking conception of God to complete this response.

Abstract: It is a commonly held perception amongst biomechanists, sports medicine practitioners, baseball coaches and players, that an individual baseball player's style of throwing or pitching influences their performance and susceptibility to injury. With the results of a series of focus groups with baseball managers and pitching coaches in mind, the available scientific literature was reviewed regarding the contribution of individual aspects of pitching and throwing mechanics to potential for injury and performance. After a discussion of the limitations of kinematic and kinetic analyses, the individual aspects of pitching mechanics are discussed under arbitrary headings: Foot position at stride foot contact; Elbow flexion; Arm rotation; Arm horizontal abduction; Arm abduction; Lead knee position; Pelvic orientation; Deceleration-phase related issues; Curveballs; and Teaching throwing mechanics. In general, popular opinion of baseball coaching staff was found to be largely in concordance with the scientific investigations of biomechanists with several notable exceptions. Some difficulties are identified with the practical implementation of analyzing throwing mechanics in the field by pitching coaches, and with some unquantified aspects of scientific analyses
