A hierarchy of topological tensor network states

We present a hierarchy of quantum many-body states among which many examples of topological order can be identified by construction. We define these states in terms of a general, basis-independent framework of tensor networks based on the algebraic setting of finite-dimensional Hopf C*-algebras. At the top of the hierarchy we identify ground states of new topological lattice models extending Kitaev's quantum double models [26]. For these states we exhibit the mechanism responsible for their non-zero topological entanglement entropy by constructing a renormalization group flow. Furthermore it is shown that those states of the hierarchy associated with Kitaev's original quantum double models are related to each other by the condensation of topological charges. We conjecture that charge condensation is the physical mechanism underlying the hierarchy in general.Comment: 61 page

Ethical implications of digital advertising automation: The case of programmatic advertising in Spain

La falta de eficacia de los métodos tradicionales de planificación en la publicidad tradicional, la creciente saturación publicitaria de los medios digitales y la influencia transformadora de los actores digitales en el sector han motivado la necesidad de desarrollar nuevos métodos y herramientas de publicidad para explotar de forma viable los recursos digitales que ofrece la Internet ubicua. La publicidad programática es actualmente considerada una de las formas más eficientes de automatización en este nuevo entorno de la publicidad digital, destacando su implantación en mercados publicitarios como los de EUA y Reino Unido. En el caso de España quedan aún importantes cuestiones por dilucidar, especialmente en lo relativo al grado de implementación tanto a escala nacional como regional y a las implicaciones éticas derivadas de la implementación de esta tecnología. Para arrojar luz sobre estos interrogantes hemos desarrollado una investigación cualitativa en un panel sobre una muestra de expertos con experiencia contrastada en el uso cotidiano profesional de esta tecnología. Los resultados subrayan la necesidad de capacidades de adaptación en un entorno rápidamente cambiante como el de la publicidad online, en el que las tecnologías posibilitan nuevos procesos con importantes implicaciones éticas y de reputación. A partir de la delimitación de una contradicción relevante entre las percepciones de los profesionales y los usuarios, el uso responsable de estas herramientas y la capacidad de observar las consecuencias derivadas de este uso se perfilan como un importante desafío profesional y funcional. Abstract Ineffective traditional advertising planning methods, the growing advertising saturation of digital media, and the disrupting influence of the digital players in the advertising sector have created a need for new methods and tools for advertising in today’s ubiquitous Internet. Programmatic advertising is currently considered one of the most efficient forms of automation the new online advertising environment and is excelling in major advertising markets like the US and United Kingdom. In Spain, however, there are still some important unaddressed questions regarding the level of implementation on a national and regional scale and the ethical implications derived from the implementation of this new technology. To address these points we have carried out qualitative research using a panel of experts with relevant background on the use of programmatic buying technology on a daily basis. The results stress the need for adapting capabilities in a rapidly evolving advertising sector, in which new technologies give rise to new complex processes with important ethical and reputational implications. We have identified a major contradiction between professionals’ views and users’ perceptions; the responsible use of these tools and the ability to identify the consequences of them appear to be a professional and functional challenge

Privacy paradox in the mobile environment: The influence of the emotions

The increasing relevance of personal information has sparked a broad debate on privacy issues on the ubiquitous Internet. The so called ‘privacy paradox’ aims to explain through rational decision-making models the contradictions between stated digital privacy concerns and the actual behaviors in mobile platforms. An analysis of the emotions that arise when users know about unauthorized personal data disclosure is proposed. A survey of smartphone users was conducted shortly after the Cambridge Analytica / Facebook scandal took place, in order to analyze the nature and intensity of a user’s emotions in relation to their knowledge of privacy breaches. The results support the paradox of privacy from an emotional perspective: although the reported emotions are intense, there is no relationship between the management that users make of their privacy settings in social networks and mobile applications and the nature and intensity of the emotions reported

Plan estratégico de la Corporación Minera Fortuna Silver Mines 2016-2025

Fortuna Silver Mines Inc. (FSM) fue fundada en el año 2005 en Vancouver, Canadá, e inicia su participación en el mercado de capitales en la bolsa de Toronto (TSX). El mismo año compra la operación minera Caylloma en el Perú y en el año 2006 la referida mina reinicia sus operaciones comerciales, luego de haberse rehabilitado para las nuevas exigencias. En términos de fuentes primarias, se ha utilizado información de la página web de FSM, recalcando que esta corporación cotiza en las bolsas de Toronto (TSX) y de Nueva York (NYSE), motivo por el cual la información que consigna es consistente y pública, además es constantemente auditada y regulada por la Canadian Securities Administrators (CSA) y la Securities and Exchange Commission (SEC), ambas entidades reguladoras del mercado de valores de Canadá y Estados Unidos, respectivamente. Por el aspecto corporativo de la presente investigación, necesariamente se hacen referencias obligatorias, como por ejemplo sobre las comparaciones de la gobernanza de FSM con los principios del gobierno corporativo de la OCDE, la gestión de riesgos con el COSO 2013 y el alineamiento de las estrategias con las 7s de McKinsey, las que no necesariamente son avaladas por FSM. También cabe mencionar que los cálculos de producción de minerales es un ensayo con fines académicos, sustentado en las reservas y recursos de mineral que tiene FSM y que proponemos ampliar como parte del incremento de la cuota de mercado, a fin de cumplir con la visión. Los datos usados en el flujo de caja son asumidos solo con el rigor académico, y no son datos proveídos por FSM

Giants with feet of clay: the sustainability of the business models in music streaming services

This paper examines the sustainability of the recorded music industry from the perspective of music performers. Music streaming platforms, or digital music service providers (DMSPs), have changed the recorded music industry paradigm since the middle of the 2010s. Business models for performers have evolved from royalty agreements based on sales to more complex remuneration systems based on revenues from a combination of (ad-based) free and paid subscriptions. Previous research has mainly focused on the examination of the business models of streaming services from the point of view of the innovation players (digital platforms) and/or the traditional dominant intermediaries (record labels and publishers). However, not all innovation-driven transformations are sustainable. In this paper, we argue that the sustainability of the main business models in the music industry demands the consideration of the performers’ perspective. We combine a qualitative approach with primary and secondary data sources to investigate the sustainability of existing trends of business models and business practices for different categories of performers, including both monetary values and a description of how revenues are shared. We conclude that DMSPs foster an asymmetric value chain in which the creative players barely capture value while technology-based innovations increase the capability of DMSPs to generate and capture value. Finally, we outline some alternative business models looking for the long-term sustainability of the digital music marketplace

From Social Web to Mobile 2.0: The 2.0 paradigm in the mediatization process of mobile communications

Due to their increasing connectivity and processing power, mobile devices are engaged in a process of mediatization that involves, on one side, conventional media related paradigms (standardized contents, pay per access, individualized passive consumption) and, on the other side, the Social Web related 2.0 paradigm (personalized and user generated content, third party open environments, collaborative work, prevalence of ‘sharing’ logics, etc.). This paper poses a general framework of those factors that enable the relevance of the Web 2.0 paradigm in the current development of market and data consumption in mobile devices, including some conceptual outline that may prove useful in future research of the evolution of mobile content production, business and consumption models

Cloud media video encoding:review and challenges

In recent years, Internet traffic patterns have been changing. Most of the traffic demand by end users is multimedia, in particular, video streaming accounts for over 53%. This demand has led to improved network infrastructures and computing architectures to meet the challenges of delivering these multimedia services while maintaining an adequate quality of experience. Focusing on the preparation and adequacy of multimedia content for broadcasting, Cloud and Edge Computing infrastructures have been and will be crucial to offer high and ultra-high definition multimedia content in live, real-time, or video-on-demand scenarios. For these reasons, this review paper presents a detailed study of research papers related to encoding and transcoding techniques in cloud computing environments. It begins by discussing the evolution of streaming and the importance of the encoding process, with a focus on the latest streaming methods and codecs. Then, it examines the role of cloud systems in multimedia environments and provides details on the cloud infrastructure for media scenarios. After doing a systematic literature review, we have been able to find 49 valid papers that meet the requirements specified in the research questions. Each paper has been analyzed and classified according to several criteria, besides to inspect their relevance. To conclude this review, we have identified and elaborated on several challenges and open research issues associated with the development of video codecs optimized for diverse factors within both cloud and edge architectures. Additionally, we have discussed emerging challenges in designing new cloud/edge architectures aimed at more efficient delivery of media traffic. This involves investigating ways to improve the overall performance, reliability, and resource utilization of architectures that support the transmission of multimedia content over both cloud and edge computing environments ensuring a good quality of experience for the final user

Evolutionary trends of digital content in mobile applications

In recent years, mobile applications have come to constitute an ecosystem of their own, becoming an important driver for innovation. The consolidation of mobile applications as the prevalent interface for content access has consequences for the production, distribution and consumption of content, merging the functional spheres of digital content: performance, creation, management and communication. This paper proposes a functional typology of mobile content applications, along with an evolutionary analysis model. It analyses the functional evolution of 153 versions of 12 relevant applications developed during two years (March 2013 through March 2015). Though statistical representativeness is limited, the sample analysis allowed validation of the model. The results point to intervention capacity and communication capacity over content as important value-added drivers in mobile content applications, although not in homogeneous terms for all the kinds of mobile applications analysed
