CRISE ECONÔMICA COMO POLÍTICA DE DESMANCHE DE DIREITOS SOCIAIS
Get PDFO artigo se propõe a apresentar um panorama das relações de trabalho diante da perenização do status de alerta global econômico nas últimas três décadas – amplificado pela mídia corporativista – atrelada ao declínio da pauta do welfare state e a ascensão de governos conservadores no ocidente inauguram um novo termo da engenharia do capital – que sempre se reinventa em movimentos autofágicos. Em nações democraticamente mais pueris como o Brasil surge o cenário perfeito para justificar o avanço demolitório sobre conquistas sociais que sequer se materializaram numa malograda tentativa de manter altos índices de produtividade diante do cenário geopolítico e econômico – muitas vezes empregando medidas que não lograram êxito a médio prazo em nações europeias ou nossos vizinhos latino-americanos, especialmente no que tange a reformas legislativas açodadas sob o discurso da austeridade
Mechanisms to Housing Rights implementation in Barcelona: Balancing act between private landlords and low-income tenants
No full textIn recent years, Barcelona has been a pioneer in the implementation of PRO-Housing Right policies. Unfortunately, these measures can be considered too radical and not necessarily efficient in a long-term scenario. Private landlords are at the center of this challenge, being that they are the stakeholder that might potentially be the solution and negotiate a balance between the two sides of the coin. On the one hand, a housing rental real estate market is shown that depends on the owners and investors, so its stability is dictated by the interest and the ttractiveness it has. Cases such as Real Estate Investment Trusts are the financial mechanism that allows indirect investment to come to the city and higher tax collection that is reflected in the infrastructure of the city. On the other, big private landlords such as opportunistic private equity funds are responsible for managing the properties and, therefore, responsible for the conditions of the tenants. Which, in recent years, have been affected the adequacy of the house. In this way, the question that will guide this research arises, what are the challenges between real estate management models and securing housing rights for low-income tenants in Barcelona? Articles, policy documents, and annual reports will be investigated to explore the investment practices of different companies (to be defined). To establish a complete view of the local investment practices of the SOCIMIs studied. The research will be divided in three sections fallowing the logic of the research questions.Aalbers M B (2016) The Financialisation of Housing: A Political Economy Approach.

Performance of network coded systems supported by automatic repeat request
No full textInspired by the network information theory, network coding was invented in 2000. Since then, the theory and application of network coding have received intensive research and various network coding schemes have been proposed and studied. It has been demonstrated that the packet-level network coding has the potential to outperform the traditional routing strategies in packet networks. By taking the advantages of the information carried by the packets sent to different receivers (sinks) in a packet network, packet-level network coding is capable of reducing the number of packets transmitted over the network. Therefore, the packet-level network coding employs the potential for boosting the throughput of packet networks. By contrast, the symbol-level network coding, which is also referred to as the physical-layer network coding, is capable of exploiting interference instead of avoiding it for improving the channel capacity and/or enhancing the reliability of communications. In this thesis, our focus is on the packet-level network coding.Performance of communication systems with network coding has been widely investigated from different perspectives, mainly under the assumption that packets are reliably transmitted over networks without errors. However, in practical communication networks, transmission errors always occur and error-detection or error-correction techniques are required in order to ensure reliable communications. Therefore, in this report, we focus our attention mainly on studying the performance of the communication networks with packet-level network coding, where Automatic Retransmission reQuest (ARQ) schemes are employed for error protection. Three typical ARQ schemes are invoked in our research, which are the Stop-and-Wait ARQ (SW-ARQ), Go-Back-N ARQ (GBN-ARQ) and the Selective-Repeat ARQ (SR-ARQ). Our main concern is the impact of network coding on the throughput performance of network coding nodes or networks containing network coding nodes. Additionally, the impact of network coding on the delay performance of network coding nodes or coded networks is also addressed.In a little more detail, in Chapter 3 of the thesis, we investigate the performance of the networks employing packet-level network coding, when assuming that transmission from one node to another is not ideal and that a certain ARQ scheme is employed for error-control. Specifically, the delay characteristics of general network coding node are first analyzed. Our studies show that, when a coding node invokes more incoming links, the average delay for successfully forming coded packets increases. Then, the delay performance of the Butterfly networks is investigated, which shows that the delay generated by a Butterfly network is dominated by the communication path containing the network coding node. Finally, the performance of the Butterfly network is investigated by simulation approaches, when the Butterfly network employs SW-ARQ, GBN-ARQ, or SR-ARQ for error-control. The achievable throughput, the average delay as well as the standard deviation of the delay are considered. Our performance results show that, when given a packet error rate Packet Error Rate (PER), the SR-ARQ scheme is capable of attaining the highest throughput and resulting in the lowest delay among these three ARQ schemes.In Chapter 4, the steady-state throughput of general network coding nodes is investigated, when the SW-ARQ scheme is employed. We start with considering a Two-Input-Single-Output (2ISO) network coding node without queueing buffers. Expressions for computing the steady-state throughput is derived. Then, we extend our analysis to the general H-Input-Single-Output (HISO) network coding nodes without queueing buffers. Finally, our analytical approaches are further extended to the HISO network coding nodes with queueing buffers. A range of expressions for evaluating the steady-state throughput are obtained. The throughout performance of the HISO network coding nodes is investigated by both analytical and simulation approaches. Our studies in this chapter show that the throughput of a network coding node decreases, as the number of its incoming links increases. This property implies that, in a network coding system, the coding nodes may form the bottlenecks for information delivery. Furthermore, the studies show that adding buffers to the network coding node may improve the throughput performance of a network coding system.Then, in Chapters 5 and 6, we investigate the steady-state throughput performance of the general network coding nodes, when the GBN-ARQ in Chapter 5 or the SR-ARQ in Chapter 6 is employed. Again, analytical approaches for evaluating the steady-state throughput of the general network coding nodes are concerned and a range of analytical results are obtained. Furthermore, the throughput performance of the network coding nodes supported by the GBN-ARQ or SR-ARQ is investigated by both simulations and numerical approaches.Finally, in Chapter 7, the conclusions extracted from the research are summarized and the possible directions for future research are proposed

El resultado de esta reunión se encuentra en: Carlos Pereyra et al., Historia ¿para qué?, México, Siglo XXI editores, 1980.7 Jean Chesneaux plantea que el análisis histórico permite definirnos a nosotros mismos; su función es la de permitir el diálogo entre el pasado y el presente y no solamente se trata de recolectar datos que pertenecen a un tiempo lejano. Véase Le mouvement paysan chinois 1840-1949, París, Editions du Seuil, 1976, p. 7.8 Para un recuento de la organización de archivos estatales y de la fundación de nuevas instituciones de historia en provincia, véase José María Muriá, "Apuntes sobre el estado actual de la historiografía regional mexicana", Panorama actual de la historiografía mexicana, México, Instituto Doctor José María Luis Mora, 1983, pp. 5-15.

Este autor tiene un magnífico análisis de los regionalismos a través de la historia, véase: "La nación versus las regiones", La Jornada Semanal, México, 25 de enero de 1987; y "Los auges del regionalismo", La Jornada Semanal, México, 1o. de febrero de 1987.14 Van Young, op. cit., 1987, p. 257.15 Mario Cerutti desarrolla los conceptos de "visión regional" y de "enfoque regional" como parte de una metodología contrapuesta a los análisis centralistas. En este sentido estoy de acuerdo, pero yo no lo utilizo como sinónimo de historia regional. Véase: "Monterrey y su ámbito regional (1850-1910).

Dice así: “... el control de ciertas clases dominantes 'cierra' la región. Esa dimensión política no es una instancia separada de la economía; por el contrario, es o será de la imbricación de las dos instancias que podrá surgir más completo el concepto que aquí se propone, por lo menos en la tradición teórica del marxismo. El 'cierre' de una región por sus clases dominantes requiere, exige y solamente se da por lo tanto, en cuanto esas clases dominantes consiguen reproducir la relación social de dominación, o más claramente las relaciones de producción. Y en esa reproducción, obstaculizan y bloquean la penetración de formas diferenciadas de generación de valor y de nuevas relaciones de producción. La apertura de la región y la consiguiente 'integración' nacional, en el largo camino hasta la disolución completa de las regiones, ocurre cuando ya no es posible seguir reproduciendo la relación social, y por esa imposibilidad se cuela la pérdida de hegemonía de las clases dominantes locales y su sustitución por otras, de carácter nacional e internacional.

Revista Americana de Ciencias Sociales, núm. 13, México, Instituto de Investigaciones Doctor José María Luis Mora, enero-abril de 1989, p. 39.28 Pablo Serrano dice que: "la definición de región involucra otro principio metodológico que todo regionalista debe poseer, como punto de partida y como constante del análisis, y que se refiere a la concepción de la región como un todo concreto y específico (no sólo en cuanto al escenario espacial, sino en cuanto a los fenómenos que se analizan o estudian)". Pablo Serrano, op. cit., p. 9.En este ensayo se pretende analizar algunas cuestiones metodológicas sobre la producción de la historia regional y la historia nacional. Para ello se partirá de un símil que presentan las artes gráficas: la cuestión de la “figura” y el “fondo”. Douglas R. Hofstadter, profesor de Ciencia de la Computación de la Universidad de Indiana, analiza el contenido de una ilustración y señala que cuando una figura está dibujada en un cuadro, por ejemplo una forma humana o una naturaleza muerta, este “espacio positivo” tiene como consecuencia inevitable una forma complementaria, es decir, el resto del cuadro, llamado fondo o “espacio negativo”. La mayoría de los dibujos no tiene una relación figura-fondo, o esa relación no tiene especial importancia para el artista, pues se interesa más por la figura que por el fondo, dado que el tratamiento de este último está, por lo general, dominado por la necesidad de hacer destacar la figura. El tratamiento del fondo está “dominado” por una especie de imposición de la figura misma. En este sentido el fondo no es más que la consecuencia de la figura
What's the Matter with Extended Techniques? Getting Beyond the Stigma in the Horn and Percussion Repertoire
Get PDFFor this project I prepared a series of recitals featuring music for horn and percussion, in which the horn part featured extended horn techniques. For this project, I considered anything beyond the open or muted horn an extended technique. These techniques range from the common hand-stopped note passages to complex new techniques involving half-valves, multi-phonics, and more, for new sounds desired by the composer. There are several pieces written for solo horn and percussion, with ensembles ranging from simple duets to solo horn with a full percussion ensemble. However, few include extended techniques for the horn. All of these select pieces are lesser known because of their difficulty, primarily because of the challenge of the extended techniques requested by the composer.
In the introduction to this paper I give a brief background to the project, where the current repertoire stands, and my experiences with commissioning works for this genre. I then give a brief history and how-to on the more common extended techniques, which were found in almost every piece. I separated these techniques so that they could be referenced in the performance notes without being extremely repetitive in their description. Then follows the main performance notes of the repertoire chosen, which includes a brief description of the piece itself and a longer discussion for performers and composers who wish to learn more about these techniques. In this section my primary focus is the extended techniques used and I provide score samples with permission to further the education of the next musicians to tackle this genre. All works performed for this project were recorded and accompany this paper in the Digital Repository at the University of Maryland (DRUM).
The following works were included in this project:
o Howard J. Buss, Dreams from the Shadows (2015)
o Howard J. Buss, Night Tide (1995)
o George Crumb, An Idyll for the Misbegotten, trans. Robert Patterson (1986/1997)
o Charles Fernandez, Metamorphosis: A Horn’s Life, “Prenatal and Toddler” (2016, unfinished)
o Helen Gifford, Of Old Angkor (1995)
o Douglas Hill, Thoughtful Wanderings… (1990)
o Pierre-Yves Level, Duetto pour Cor en Fa et Percussion (1999)
o David Macbride, Elegy for Horn and Timpani (2009)
o Brian Prechtl, A Song of David (1995)
o Verne Reynolds, HornVibes (1986)
o Pablo Salazar, Cincontar (2016)
o Mark Schultz, Dragons in the Sky (1989)
o Faye-Ellen Silverman, Protected Sleep (2007)
o Charles Taylor, Sonata for Horn and Marimba (1991)
o Robert Wolk, Tessellations (2016)
With this project, I intend to promote these pieces and the techniques used to encourage more works written in this style, and reveal to fellow horn players that the techniques should not prevent these great works from being performed. Due to the lack of repertoire, I successfully commissioned new pieces featuring extended techniques, which were featured in the final recital
MULHERES DE PALAVRA: COAUTORAS NA HERMENÊUTICA BÍBLICA E EM SEUS PROPÓSITOS TEOLÓGICOS
Get PDFA hermenêutica é um campo aberto para dimensões e perspectivas ainda não compreendidas. A mulher, nesse cenário, é convidada a participar das compreensões e descobrir, por meio de seus esforços, as mensagens que os textos bíblicos demonstram. Neste artigo, caminhamos por três margens que se completam de uma forma dinâmica. A hermeneuta é convidada a entender o seu propósito bem como o propósito do texto. Em segundo lugar, compreender para interpretar é um dos passos hermenêuticos para que a mulher capte a mensagem do autor do texto bíblico. Conclui-se, que a mulher é uma coautora dos propósitos teológicos. WOMEN OF WORD: COAUTHORS IN BIBLICAL HERMENEUTICS AND IN THEIR THEOLOGICAL PURPOSESAbstractHermeneutics is an open field for dimensions and perspectives not yet understood. The woman, in this scenario, is invited to participate in the understandings and discover, through her efforts the messages that the Biblical texts demonstrate. In this article, we walk through three margins that complemente each other in a dynamic way. The hermenetist is invited to understand its purpose as well as the purpose of the text. Secondly, understanding to interpret is one of the hermeneutical steps for the woman to captura the message of the author of the biblical text. It concludes that woman is a co-author of the theological purposes.Key words: Hermeneutics. Woman. Interpreter. Interpretative Co-authorship
HRM, organizational capacity for change, and performance: a global perspective
Get PDFThis special issue brings together a variety of articles, each one enriching understanding about whether and how human resource management (HRM) influences organizational performance (however defined) against a backdrop of complex change. We present a preliminary framework that enables us to integrate the diverse themes explored in the special issue, proposing a mediating role for organizational change capacity (OCC). OCC represents a particular subset within the resource- based literature labeled as “dynamic capabilities.” Although not well researched, there is evidence that OCC is positively associated with firm performance and that this relationship is stronger given conditions of high uncertainty. Our framework reflects on external and internal parameters, which we suggest moderate the relationship between human resource management (HRM), OCC, and organizational performance. Our intention is to provide compelling insight for both practitioners and researchers, especially those whose remit extends beyond national boundaries, with reference to areas of the globe as disparate as Greece, Ireland, Pakistan, Switzerland, and the United Kingdom
Low precision matrix multiplication for efficient deep learning in NVIDIA Carmel processors
Get PDF[EN] We introduce a high performance, multi-threaded realization of the gemm kernel for the ARMv8.2 architecture that operates with 16-bit (half precision)/queryKindly check and confirm whether the corresponding author is correctly identified. floating point operands. Our code is especially designed for efficient machine learning inference (and to a certain extent, also training) with deep neural networks. The results on the NVIDIA Carmel multicore processor, which implements the ARMv8.2 architecture, show considerable performance gains for the gemm kernel, close to the theoretical peak acceleration that could be expected when moving from 32-bit arithmetic/data to 16-bit. Combined with the type of convolution operator arising in convolutional neural networks, the speed-ups are more modest though still relevant.This work was supported by projects TIN2017-82972-R and RTI2018-093684-B-I00 from the Ministerio de Ciencia, Innovacion y Universidades, project S2018/TCS-4423 of the Comunidad de Madrid, project PR65/19-22445 of the UCM, and project Prometeo/2019/109 of the Generalitat Valenciana.San Juan-Sebastian, P.; Rodríguez-Sánchez, R.; Igual, FD.; Alonso-Jordá, P.; Quintana-Ortí, ES.

Euclid preparation: LIII. LensMC, weak lensing cosmic shear measurement with forward modelling and Markov Chain Monte Carlo sampling
No full textEuclid Collaboration: et al.LENSMC is a weak lensing shear measurement method developed for Euclid and Stage-IV surveys. It is based on forward modelling in order to deal with convolution by a point spread function (PSF) with comparable size to many galaxies, sampling the posterior distribution of galaxy parameters via Markov chain Monte Carlo, and marginalisation over nuisance parameters for each of the 1.5 billion galaxies observed by Euclid. We quantified the scientific performance through high-fidelity images based on the Euclid Flagship simulations and emulation of the Euclid VIS images, realistic clustering with a mean surface number density of 250 arcmin−2 (IE < 29.5) for galaxies, and 6 arcmin−2 (IE < 26) for stars, and a diffraction-limited chromatic PSF with a full width at half maximum of 0′.′2 and spatial variation across the field of view. LENSMC measured objects with a density of 90 arcmin−2 (IE < 26.5) in 4500 deg2. The total shear bias was broken down into measurement (our main focus here) and selection effects (which will be addressed in future work). We found measurement multiplicative and additive biases of m1 = (−3.6 ± 0.2) × 10−3, m2 = (−4.3 ± 0.2) × 10−3, c1 = (−1.78 ± 0.03) × 10−4, and c2 = (0.09 ± 0.03) × 10−4; a large detection bias with a multiplicative component of 1.2 × 10−2 and an additive component of −3 × 10−4; and a measurement PSF leakage of α1 = (−9 ± 3) × 10−4 and α2 = (2 ± 3) × 10−4. When model bias is suppressed, the obtained measurement biases are close to Euclid requirement and largely dominated by undetected faint galaxies (−5 × 10−3). Although significant, model bias will be straightforward to calibrate given its weak sensitivity on galaxy morphology parameters.
