Comparison of input devices in an ISEE direct timbre manipulation task

The representation and manipulation of sound within multimedia systems is an important and currently under-researched area. The paper gives an overview of the authors' work on the direct manipulation of audio information, and describes a solution based upon the navigation of four-dimensional scaled timbre spaces. Three hardware input devices were experimentally evaluated for use in a timbre space navigation task: the Apple Standard Mouse, Gravis Advanced Mousestick II joystick (absolute and relative) and the Nintendo Power Glove. Results show that the usability of these devices significantly affected the efficacy of the system, and that conventional low-cost, low-dimensional devices provided better performance than the low-cost, multidimensional dataglove

The Babbage principle after evolutionary economics

In this paper we analyse the cognitive roots of the division of labour and relate it to the reduction of tacitness in the organisation and technology of a firm. We study the interaction between efforts of knowledge codification and problems of control in production from an evolutionary and complex systems perspective. By applying our framework to the emergence of white-collar work in the late 19th century and the modern knowledge economy we assert that property rights and limits to codification of knowledge are important forces shaping the process of organisational and technological change.research and development ;

Consistency of Spectral Hypergraph Partitioning under Planted Partition Model

Hypergraph partitioning lies at the heart of a number of problems in machine learning and network sciences. Many algorithms for hypergraph partitioning have been proposed that extend standard approaches for graph partitioning to the case of hypergraphs. However, theoretical aspects of such methods have seldom received attention in the literature as compared to the extensive studies on the guarantees of graph partitioning. For instance, consistency results of spectral graph partitioning under the stochastic block model are well known. In this paper, we present a planted partition model for sparse random non-uniform hypergraphs that generalizes the stochastic block model. We derive an error bound for a spectral hypergraph partitioning algorithm under this model using matrix concentration inequalities. To the best of our knowledge, this is the first consistency result related to partitioning non-uniform hypergraphs.Comment: 35 pages, 2 figures, 1 tabl

CURRENT ISSUES AFFECTING TRADE AND TRADE POLICY: AN ANNOTATED LITERATURE REVIEW

This review provides a base of literature describing current issues and research on the impacts of lobalization and the industrialization of agriculture and recent approaches to analyze and model agricultural trade and trade policies. Three key factors of the survey are differentiated goods, global economic integration and international supply chain linkages. The review covers 182 publications, which are presented alphabetically by author with a brief annotation describing how it relates to the above criteria. The articles are also indexed by keyword. A brief summary highlights the documented literature and includes a series of issues for future discussion and research.International Relations/Trade,

Selected Works in Bioinformatics

This book consists of nine chapters covering a variety of bioinformatics subjects, ranging from database resources for protein allergens, unravelling genetic determinants of complex disorders, characterization and prediction of regulatory motifs, computational methods for identifying the best classifiers and key disease genes in large-scale transcriptomic and proteomic experiments, functional characterization of inherently unfolded proteins/regions, protein interaction networks and flexible protein-protein docking. The computational algorithms are in general presented in a way that is accessible to advanced undergraduate students, graduate students and researchers in molecular biology and genetics. The book should also serve as stepping stones for mathematicians, biostatisticians, and computational scientists to cross their academic boundaries into the dynamic and ever-expanding field of bioinformatics

Legal and Social Implications of the 3D Printing Revolution

ABSTRACT Emerging 3D printing technologies bring with it the potential to transform everyday consumers into manufacturers of every product imaginable. However, this impending wave of newfound technological capability is bound to crash against our present conventional system of laws and regulations. In this paper, the strengths and weaknesses of our current intellectual property framework are examined, and its ability to tackle the future 3D printing market is assessed. Particular attention is paid to our modern formation of copyright and patent law, including an analysis of the Digital Millennium Copyright Act (DMCA), the Repair-Reconstruction Doctrine and other substantial legal protocol. The legal battle between the Napster file-sharing service and the larger music industry is also explored, as it provides key insight into similar intellectual property divergences that may soon drive a stake between 3D printing businesses and more traditional manufacturers of physical goods. Finally, this paper suggests modifications to be made towards traditional sales models, the Repair-Reconstruction Doctrine, the implementation of the DMCA protections, and our application of the Fair Use Doctrine
