No full textΗ ανάπτυξη είναι το πιο ενδιαφέρον θέμα και πρόβλημα στον σύγχρονο κόσμο και κατέχει την σημαντικότερη θέση στην οικονομική και κοινωνικοπολιτική σκέψη. Οι στατιστικές, με τους αμείλικτους αριθμούς τους, δίνουν ψυχρά την εικόνα του “παράδεισου” της εποχής μας και πείθουν για την… ανάπτυξη της σημερινής ανθρωπότητας, σε παγκόσμια κλίμακα, αφού ετησίως: 570 εκατομμύρια άνθρωποι υποσιτίζονται, 25 εκατομμύρια πεθαίνουν από πείνα, ενώ 450 δισεκατομμύρια δολάρια πάνε στους εξοπλισμούς! (1979). Στην παρούσα μελέτη ασχολούμαι με την ανάπτυξη της Ελλάδας, προσπαθώντας να δώσω απάντηση στο ερώτημα: Πού βρίσκεται σήμερα η Ελλάδα, από αναπτυξιακή άποψη, με βάση τους επίσημους αριθμούς των έγκυρων στατιστικών; Στόχος πρωταρχικός της διατριβής είναι να αναζητηθούν & προταθούν «ορθολογικές κατευθύνσεις αναπτυξιακών προοπτικών», γεγονός που επετεύχθη με την αμέριστη και πολύτιμη βοήθεια και συνδρομή του επιστημονικού καθοδηγητή μου, ακαδημαϊκού, Profes. Univers. Dr Docient N.N. Constantinescu.Στο πόνημα καταδεικνύεται το «πώς» και το «γιατί» η Ελλάδα είναι χώρα περιφερειακή μέσου επιπέδου ανάπτυξης, με οξυμένες ενδοπεριφερειακές και διαπεριφερειακές ανισότητες και που ανήκει στην περιφέρεια του παγκόσμιου καπιταλιστικού συστήματος. Τα στατιστικά δεδομένα είναι της περιόδου 1950-1980, και μέσα από αυτά –και την ανάλυσή τους– προκύπτουν οι εξελίξεις όλων των τομέων της ελληνικής οικονομίας και κοινωνίας, και κατά συνέπεια συντίθενται και οι προτάσεις, που κατά την άποψή μου μπορούν να συμβάλουν στην επίλυση των υφιστάμενων προβλημάτων
Hip-hop time machine - re-imagining the ‘phonographic’ in sample-based hip-hop record production: research design for contemporary forms of creative audio practice
No full textThe article embarks on a two-fold investigation, examining the aesthetic implications of sample-based record production using re-imagined phonographic sources, and exploring applied research design for contemporary forms of music-making. Challenging traditional models of musicological analysis, the author demonstrates how multi-methods research leverages the study of ‘meta’ genres of creative practice
Sample magic: (Conjuring) phonographic ghosts and meta-illusions in contemporary hip-hop production
No full textSampling has been criticised as “a mixture of time-travel and seance”, “the musical art of ghost co-ordination and ghost arrangement”, and a process that “doubles (recording’s) inherent supernaturalism” (Reynolds 2012, pp. 313-314). Yet out of all the sample-based music forms, hip-hop receives the lion’s share of attention in popular music literature; critics are puzzled by its appeal, scholars identify a plethora of problems in its function, and practitioners and audiences alike are mesmerised by its effect. Rap producers attribute an inherent ‘magic’ to working with past phonographic samples and fans appear spellbound by the resulting ‘supernatural’ collage. The author examines the music’s unique recipe of phonographic juxtaposition, exploring the conditions of this ascribed ‘magic’, investigating gaps in perception (Lehrer 2009) between emotional and intellectual effect, and deciphering parallels in the practice and vocabulary mobilised against a range of genres in performance magic

No full textExtraction of consensus protein patterns in regions containing non-proline <it>cis </it>peptide bonds and their functional assessment
No full textAbstract Background In peptides and proteins, only a small percentile of peptide bonds adopts the cis configuration. Especially in the case of amide peptide bonds, the amount of cis conformations is quite limited thus hampering systematic studies, until recently. However, lately the emerging population of databases with more 3D structures of proteins has produced a considerable number of sequences containing non-proline cis formations (cis-nonPro). Results In our work, we extract regular expression-type patterns that are descriptive of regions surrounding the cis-nonPro formations. For this purpose, three types of pattern discovery are performed: i) exact pattern discovery, ii) pattern discovery using a chemical equivalency set, and iii) pattern discovery using a structural equivalency set. Afterwards, using each pattern as predicate, we search the Eukaryotic Linear Motif (ELM) resource to identify potential functional implications of regions with cis-nonPro peptide bonds. The patterns extracted from each type of pattern discovery are further employed, in order to formulate a pattern-based classifier, which is used to discriminate between cis-nonPro and trans-nonPro formations. Conclusions In terms of functional implications, we observe a significant association of cis-nonPro peptide bonds towards ligand/binding functionalities. As for the pattern-based classification scheme, the highest results were obtained using the structural equivalency set, which yielded 70% accuracy, 77% sensitivity and 63% specificity.</p
Liturgical handbooks as tools for promoting bishops' ideological and political agendas : the example of Cambrai/Arras in the eleventh century
No full textThis paper examines the political and ideological implications of liturgical handbooks and their usage as tools for promoting episcopal agendas. By focussing on the ritual for imperial crowning, preserved in the pontifical Cologne, Erzbischofliche Didzesan- and Dombibliothek, 141, from the border diocese of Cambrai/Arras, that was drawn up in the middle of the eleventh century, the author argues that it is possible to interpret the structure and content of episcopal handbooks in the light of their compilers' multiple practical and theoretical objectives, and to regard them as very consciously compiled to reflect political and ideological messages. The article shows how the scripting of a unique interpretation of the ritual of imperial coronation entailing a considerable strengthening of the emperor's position within the ceremony in an episcopal handbook for local use was employed by the bishop to promote his political and ideological agenda, to valorise his episcopal authority, and to underscore the imperial identity of the diocese of Cambrai and its bishops in times of tension
A Theory of Music Analysis: On Segmentation and Associative Organization by Dora A. Hanninen (review)
No full textIn lieu of an abstract, here is a brief excerpt of the content:
Comprising research spanning over a decade, A Theory of Music Analysis constitutes a comprehensive account and a culmination of Dora A. Hanninen’s work to date. To the extent that no theory of music is independent of analysis, this work is indispensable as a theory of analysis. The main (philosophical) concern of the book is how to create a precise analytical language, one that can secure a credible interpretation; intertwined with this is a (practical) concern with how to employ this language in a way that reflects the individual analyst’s flair. Analytical applications are not set against theory as singular instances of ready-made methods; on the contrary, by negating the usual rhetoric of theory and analysis, Hanninen sets out to provide a kind of metatheory, independent of the particular existing music-theoretic tools that it aims to encompass. This level of interaction between Hanninen’s overarching metatheory (or simply “theory”) and particular, or what she calls orienting theories is, I think, most intriguing and—although at times not easy to ascertain—promising.
From the outset, the author wishes to safeguard the “interpretive autonomy and imagination of the individual analysts” who use the theory (p. 4). In this spirit, the book addresses music theorists, analysts, and musicologists. It is ideal for a postgraduate and academic readership and it could serve as a main reference item in analysis courses. Analysis scholars will appreciate its focus on segmentation. From atonal-theoretic to semiotic methods, segmentation relies on interpretation of the music score. Hanninen endeavors to formalize segmentation protocols by constructing three basic types of criteria; although she provides comprehensive lists for the three types, these lists are left open-ended.
The book encompasses a wide range of Western music traditions from the baroque onward. This feature is one among its several qualities of methodological flexibility, afforded precisely by the relation between metatheory and orienting theory. From Bach to Brahms and from Varèse to Babbitt, the first half of the book abounds in examples and indicative applications of analytical tools and concepts. The second half comprises a set of six detailed analyses of mostly piano-based music, two European (Beethoven and Debussy), and four American (Nancarrow, Riley, Feldman, and Morris). Analytically, the book employs, and thus presupposes, a firm knowledge of common-practice tonality, serial systems, atonal theory, and Schenkerian analysis. These four approaches suffice to cover the repertoire with which Hanninen engages. Having said that, the flexibility just mentioned should provide enough space for one to apply new orienting theories to analysis (e.g., the often-idiosyncratic approaches by Iannis Xenakis, who is mentioned briefly).
Orientations and criteria for segmentation form the theory’s conceptual part, while associative sets and organization lie on the objective end, segments being the interface. The schematic of the theory is a synoptic representation of these five levels, which interact within three domains: sonic (psychoacoustic), contextual (associative), structural (theoretical). Thus, orientations refer respectively to disjunction, association, theory; and criteria can be sonic, contextual, structural, or linked as structural–sonic, structural–contextual.
Any analyst of the post-tonal repertoire will appreciate the difficulties around segmentation strategies. Allen Forte’s distinction between primary and composite segments, or the practice of imbrication, can be useful, but his reference to contextual criteria for segmentation was left un-systematized. In practice, this was counter-balanced by a refining of the segmentation process according to both those contextual criteria and set relations (The Structure of Atonal Music [New Haven, CT: Yale University Press, 1973], 91). Such practices point to a conundrum of theory and analysis: to what extent should we allow (the orienting) theory to affect our interpretation? Such problematics are usually confronted in analysis classes, where students are required to provide a convincing (as opposed to convenient) segmentation. The three types of criteria that Hanninen’s theory provides refer to disjunction (bottom-up feature extraction; sonic), association (by some kind of repetition; contextual), and specific orienting theory (compositional/analytical strategies; structural). The interaction between these three provides a sufficiently rigorous (albeit at times demanding) framework for segmentation. Following this rigorously allows one to mitigate the tension between theory and “the music.
