Optical Network Models and their Application to Software-Defined Network Management

Software-defined networking is finding its way into optical networks. Here, it promises a simplification and unification of network management for optical networks allowing automation of operational tasks despite the highly diverse and vendor-specific commercial systems and the complexity and analog nature of optical transmission. A fundamental component for software-defined optical networking are common abstractions and interfaces. Currently, a number of models for optical networks are available. They all claim to provide open and vendor agnostic management of optical equipment. In this work, we survey and compare the most important models and propose an intent interface for creating virtual topologies that is integrated in the existing model ecosystem.Comment: Parts of the presented work has received funding from the European Commission within the H2020 Research and Innovation Programme, under grant agreeement n.645127, project ACIN

The Zambra, Tourism and Discourses of Authenticity in Granada’s Flamenco Scene

The zambra is a genre and context of flamenco unique to the Gitano (Gypsy) neighbourhood of Sacromonte (Granada), which throughout its historical development has been closely intertwined with tourism. Framed by recent musical and social change in the zambra, this article examines debates regarding tourism, authenticity, and local heritage in Sacromonte. Previous research has focused on the economic and institutional dimensions of flamenco tourism with little consideration of local discourses. This article interrogates a static notion of “staged authenticity,” instead focusing on the dynamic and contested relationship between music and tourism in the context of local musical practice.This research was made viable through a doctoral studentship at the School of Music. Finally, I would like to thank the Leverhulme Trust for my current fellowship, which has enabled me to write up this research.This is a metadata record relating to an article that cannot be shared due to publisher copyright

Spanish Musical Responses to Moroccan Immigration and the Cultural Memory of al-Andalus

AbstractThe notion of a shared history across the Mediterranean is central to a number of Spanish-Moroccan musical collaborations, which draw on the notion of convivencia: the alleged peaceful coexistence between Christians, Jews, and Muslims in medieval Spain. In this article, I explore the relationship between a ‘musical’ convivencia and Moroccan immigration in Spain, focusing on two prominent case studies: Macama jonda (1983) and Inmigración (2003). Spanning a twenty-year period, I argue that these two productions illustrate shifting responses to Moroccan immigration at distinct historical moments: the post-Franco era and post-9/11. These two productions illustrate the malleability of the convivencia myth, employing it for distinct social and political purposes. I argue that Macama jonda and Inmigración should be read as products of shifting political and cultural relations between Spain and Morocco, and Spain's negotiation of its Muslim past.Leverhulme Trus

The GED and alternative learning center diploma as a factor in post-secondary persistence and success

The purpose of this paper will be to analyze how graduates of alternative learning high schools and GED certificate holders compare to traditional high school diploma recipients in terms of academic success at post-secondary institutions. A review of the existing literature and statistical analysis of entering students at a private career college will provide both a historical perspective and illustrate pertinent facts surrounding this issue. Analysis of the available information will provide the foundation for future planning and initiatives designed to improve the process or mitigate any identified inequities

Organization development as instrument to build and maintain organizational effectiveness in remote mode: a qualitative inductive research

The public-health driven COVID-19 lockdowns unpredictably forced organization development (OD) consultants to work from home in no time. As original interventions, driven by behavioral and social science knowledge were predominantly designed for face-to-face encounters, adaptation to virtual OD services was inevitable. The purpose of this study was to investigate how organization development consultants adjusted their labor activity from a predominantly face-to-face to a solely technology-mediated setting. We adopted a bottom-up, research approach to inductive concept development, following Gioia and colleagues’ methodology (2013) to study the adaptation process of 10 both external and internal OD consultants. The emergent framework suggests that adjusting to a virtual setting was a complex process that occurs in more or less sequential stages: (1) we go into action, (2) acknowledging limits, (3) an ongoing need and evolvement of a tech & tool literacy, and finally (4) the acceptance of change, resulting in an evolved state of the occupational field. The findings indicate a parallel to Lewin’s famous Three-Phase Model of Change (1951). We suggest that our emergent framework can be well applied by other occupational fields (e.g., education sector, therapy, consultancies) in a transition process to a virtual setting. To facilitate the transition in other occupational fields we outline a roadmap as guidance.Os confinamentos do COVID-19, impulsionados pela saúde pública, forçaram imprevisivelmente os consultores de desenvolvimento de organização (DO) a trabalharem a partir de casa em pouco tempo. Como as intervenções originais, impulsionadas por conhecimentos comportamentais e de ciências sociais foram predominantemente concebidas para encontros presenciais, a adaptação a serviços virtuais de DO era inevitável. O objetivo deste estudo era investigar como os consultores de desenvolvimento organizacional ajustaram a sua atividade laboral de um ambiente predominantemente presencial para um ambiente exclusivamente mediado pela tecnologia. Adoptámos uma abordagem "bottom-up", de investigação para o desenvolvimento de conceitos indutivos, seguindo a metodologia de Gioia e colegas (2013) para estudar o processo de adaptação de 10 consultores externos e internos de DO. O quadro emergente sugere que a adaptação a um cenário virtual foi um processo complexo que ocorreu em fases mais ou menos sequenciais: (1) entramos em acção, (2) reconhecimento de limites, (3) uma necessidade contínua e evolução de uma alfabetização tecnológica e de ferramentas, e finalmente (4) a aceitação da mudança, resultando num estado evoluído do campo ocupacional. Os resultados indicam um paralelo com o famoso modelo de mudança de três estágios de Lewin (1951). Sugerimos que o nosso quadro emergente seja aplicado por outros campos profissionais (por exemplo, sector da educação, terapia, consultorias) num processo de transição para um cenário virtual. Para facilitar a transição noutros campos profissionais, delineamos um roteiro como orientação

The Dynamics of Intercultural Music Making in Granada: Everyday Multiculturalism and Moroccan Integration

This article examines musical exchanges between Moroccans and Spaniards, which are often underpinned by the notion of a shared cultural heritage. Such exchanges promote intercultural dialogue and the social integration of Moroccans in Andalusia. Focusing on one individual, I explore the strategies musicians use to integrate socially and musically in Andalusian society. I examine the ways in which Moroccan musicians negotiate their day-to-day musical landscape and the tensions between overt displays of cultural difference, social integration, and musicians’ own artistic aspirations. In so doing, this article puts ethnomusicology into dialogue with scholarship on the policies and everyday realities of multiculturalism and interculturalism.This research was conducted during my Leverhulme Early Career and Fellowship (2014–17) and my European Research Council Starting Grant project entitled ‘Past and Present Musical Encounters across the Strait of Gibraltar’ (2018–23)
