Computing compatible tours for the traveling salesman problem
No full textWe consider the following natural heuristic for the Symmetric Traveling Salesman Problem: solve the subtour relaxation, yielding a solution x*, and then find the best tour x-bar that is 'compatible' with x*, where compatible means that every subtour elimination constraint that is satisfied at equality at x* is also satisfied at equality at x-bar. We prove that finding the best compatible tour is NP-hard and show that the tour can have a cost approaching 5/3 that of the optimal tour. We then describe a branch-and-cut algorithm for computing the best compatible tour, and present extensive computational results for TSPLIB instances. It turns out that, in practice, the tour is usually of very good quality. Moreover, the computational effort for computing the compatible tour is considerably smaller than that of solving the full problem with the best available software, i.e., Concorde

L.A. Tabulae ad Astra
No full textL.A.: Tabulae ad Astra (Los Angeles: Maps to the Stars) is a series of prints integrating portions of street maps of Los Angeles with gestural lines, impromptu marks from testing pen nibs, and cutting lines on boards—all unwittingly produced in the artist’s studio while working on other projects. The combined layers of intersecting and overlapping marks take on a surprising cartographic character that is reinforced by additional ancient map-like elements such as measurement grids, Latin phrases, beastiary, and scale markers. The resultant prints are also physically connected to the Los Angeles landscape, being printed on paper that was first soaked and stained in the waters of the L.A. River. Together Tabulae ad Astra plays on the constant tensions of control vs. freedom, order vs. complexity, safety vs. adventure, and city vs. wilderness.

A Look Back on the L.A. Riots: Black-Korean Relations
No full textWhat is the future of Black-Korean communities, post-L.A. riots? According to the author, there is an absence of Asian American issues in books devoted to race relations between ethnic minorities in the U.S. This thesis examines the Los Angeles riots, the histories of each group, and data from qualitative interviews. The author gives an objective and honest analysis of black-Korean relations despite racial, economic, and political biases. Methodology includes qualitative interviews of black respondents and Korean-American respondents

The Interchangeable Roles of Music and Technology in Computer-Supported Education
No full textScientific literature has frequently focused on the contribution offered by technology to support music education at various levels. A less investigated subject is the possibility of using multimedia and musical languages to encourage the acquisition of digital competences. In this vision, the roles of mediator and disciplinary goal– which in the context of computer-supported education are traditionally assigned to technology and music, respectively – are reversed. These concepts will be exemplified through applications which explore the relationship between music and technology from a new point of view, merging the two fields and making traditional roles more nuanced, thus encouraging the development of higher-order thinking skills. This paper summarizes the keynote lecture held by the author at the 4th International Conference on New Music Concepts – ICNMC 2017
Haunted narratives: politics, fiction and ghostwriting in Robert Harris’s "The Ghost"
No full textTaking as case study Robert Harris’s The Ghost, and focusing on the ‘poetics’ of ghostwriting and multiple, disseminated authorship, this article aims to highlight the crucial intersections between truth and fiction, authenticity and self-deception and the disembodying of public accountability from both the political subject and the literary author, made possible by the emergence of professional speechwriters and celebrity politicians. Suggestively embedded in this subtly intertextual novel are a number of ‘Gothic’ narrative structures and generic conventions, which range from the thematization of ghostwriting as a spectral activity, to the pervasive use of terms and images pertaining to the semantic areas of “haunting” and “the ghostly”, to neo-Gothic rewritings of landscapes and social milieus
