BowScribe: Supporting the violinist's performance model

Musicians often learn about their vision of a piece through practicing it and listening to recordings. However, this does not always free the player to develop his or her own interpretation of the piece, especially when technique is lacking. We have developed software, the BowScribe markup language, that supports a violinist in creating a ``performance model'' of a piece currently beyond his or her playing skills, by allowing the player fine control over tempo, volume, and articulation, including playing of chords, at a level of expressiveness and flexibility that is significantly beyond the MIDI playback modes of popular music notation software. BowScribe has been used by the first author (who was trained as a prfessional violinist) to create a model of the entire Bach Chaconne (edited by Glamian), a long and demanding piece of music for solo violin that has many phrases that span groups of chords as well as melodic passages. The markup language specified chords to be rolled in two classic ways, as well as a wide variety of other strokes, including greater volume for individual notes in long slurs and small but essential variations in tempo

Multiple hierarchies : new aspects of an old solution

In this paper, we present the Multiple Annotation approach, which solves two problems: the problem of annotating overlapping structures, and the problem that occurs when documents should be annotated according to different, possibly heterogeneous tag sets. This approach has many advantages: it is based on XML, the modeling of alternative annotations is possible, each level can be viewed separately, and new levels can be added at any time. The files can be regarded as an interrelated unit, with the text serving as the implicit link. Two representations of the information contained in the multiple files (one in Prolog and one in XML) are described. These representations serve as a base for several applications

Putting the Text back into Context: A Codicological Approach to Manuscript Transcription

Textual scholars have tended to produce editions which present the text without its manuscript context. Even though digital editions now often present single-witness editions with facsimiles of the manuscripts, nevertheless the text itself is still transcribed and represented as a linguistic object rather than a physical one. Indeed, this is explicitly stated as the theoretical basis for the de facto standard of markup for digital texts: the Guidelines of the Text Encoding Initiative (TEI). These explicitly treat texts as semantic units such as paragraphs, sentences, verses and so on, rather than physical elements such as pages, openings, or surfaces, and some scholars have argued that this is the only viable model for representing texts. In contrast, this chapter presents arguments for considering the document as a physical object in the markup of texts. The theoretical arguments of what constitutes a text are first reviewed, with emphasis on those used by the TEI and other theoreticians of digital markup. A series of cases is then given in which a document-centric approach may be desirable, with both modern and medieval examples. Finally a step forward in this direction is raised, namely the results of the Genetic Edition Working Group in the Manuscript Special Interest Group of the TEI: this includes a proposed standard for documentary markup, whereby aspects of codicology and mise en page can be included in digital editions, putting the text back into its manuscript context

Measuring Market Power in U.S. Industry

Non-competitive conduct can be assessed by estimating the size of the markup or Lerner index achieved in a market. The markup implies a price elasticity of demand faced by the representative firm. For a given markup, non-competitive conduct is greater the more elastic is the market elasticity of demand. The ratio of the firm's to the market elasticity is a measure of non-competitive conduct that is insensitive to the value of the monopoly. To implement this measure, both the firm's and the market elasticities of demand must be estimated. Hall shows how to estimate the markup, and hence the elasticity faced by the firm, from the cyclical behavior of productivity. To estimate the market elasticity, an instrumental variables procedure exploiting a covariance restriction between productivity shocks and demand shocks is used. Results for broad sectors of private industry and for non-durable manufacturing industries display a wide range of monopoly power.

Legislatures, Agencies, Courts and Advocates: How Laws are Made, Interpreted and Modified

This chapter explains the nature and practice of lawmaking, legal advocacy, and legal research as they relate to the field of work and family. Through reference to the Family and Medical Leave Act of 1993 as a case study, the authors explain the dynamic processes by which laws are made, interpreted and modified by legislatures, administrative agencies and courts, with the help of legal advocates. Their goal is not to provide substantive analysis of laws related to work and family, but rather to enable researchers from a range of disciplines to understand and access the legal system, as it currently exists and as it is evolving. In addition, for those inclined to change the current system through legal advocacy, this chapter provides a window into how advocates may use the lawmaking process to promote their preferred work and family policies

Seven Dimensions of Portability for Language Documentation and Description

The process of documenting and describing the world's languages is undergoing radical transformation with the rapid uptake of new digital technologies for capture, storage, annotation and dissemination. However, uncritical adoption of new tools and technologies is leading to resources that are difficult to reuse and which are less portable than the conventional printed resources they replace. We begin by reviewing current uses of software tools and digital technologies for language documentation and description. This sheds light on how digital language documentation and description are created and managed, leading to an analysis of seven portability problems under the following headings: content, format, discovery, access, citation, preservation and rights. After characterizing each problem we provide a series of value statements, and this provides the framework for a broad range of best practice recommendations.Comment: 8 page

DE-PACRR: Exploring Layers Inside the PACRR Model

Recent neural IR models have demonstrated deep learning's utility in ad-hoc information retrieval. However, deep models have a reputation for being black boxes, and the roles of a neural IR model's components may not be obvious at first glance. In this work, we attempt to shed light on the inner workings of a recently proposed neural IR model, namely the PACRR model, by visualizing the output of intermediate layers and by investigating the relationship between intermediate weights and the ultimate relevance score produced. We highlight several insights, hoping that such insights will be generally applicable.Comment: Neu-IR 2017 SIGIR Workshop on Neural Information Retrieva
