Two-phase RTD-CMOS pipelined circuits

MOnostable-BIstable Logic Element (MOBILE) networks can be operated in a gate-level pipelined fashion (nanopipeline) allowing high through output. Resonant tunneling diode (RTD)-based MOBILE nanopipelined circuits have been reported using different clock schemes including a four-phase strategy and a single-phase clock scheme. In particular, significant power advantages of single-phase RTD-CMOS MOBILE circuits over pure CMOS have been shown. This letter compares the RTD-CMOS realizations using a single clock and a novel two-phase clock solution. Significant superior robustness and performance in terms of power and area are obtained for the two-phase implementations

Digital Diasporas and transnational Identities: Media Practices of the Spanish Diaspora in Germany

The dissertation focuses, from a practice-based approach, on the processual, relational and situated character of the concept of “digital diaspora”. I selected the contemporary Spanish diaspora in Germany as a case study, applying a combination of two research methodologies: a) in-depth qualitative interviews and b) qualitative content analysis. Practice theory approaches (Reckwitz, 2002; Schatzki, 1996) seek to build social theory centred on "practices", rather than structures, systems, individuals, or interactions (Postill, 2010). RQ1 addresses both personal relationships and the public/political media practices of Spanish migrants in Germany: How do diaspora communities develop their personal relations and public-political participation within the network? To answer this question, I proposed the concept of “migrant’s digital associationism” to describe new digital logics of migrant communicative practices. It incorporates the public and political articulation 'within' the diaspora. The RQ2 addresses the processes of cultural identity and community development: How do contemporary Spanish migrants in Germany symbolically construct a sense of we-ness, Spanish-ness and otherness through their media practices? Here I specifically discuss discursive practices connected with different processes of belonging with the aim of illustrating how these identities are embedded in concrete realities. In this phase I also relate the concepts of belonging and memory, developing the construction of memory as a situated space of negotiation through certain social and communicative practices. The RQ3 constitutes the synthesis of the first question and the second, combining the conclusions drawn in both the public-private interaction and the identity analysis phase: Which role play the ICT and media practices in the construction of transnational communities and identities? Through the analysis of media practices and their processes of belonging, I develop the concept of Digital Diaspora from a practice-based approach as a contested and negotiated space in terms of belonging, but, at the same time, with a material and embodied basis

Examining the Impact of Innovation Forms on Sustainable Economic Performance: The Influence of Family Management

The aim of this research is to explore the effect that innovation, as a potential source of sustained competitive advantage and firm growth, has on the achievement of sustainable economic performance. In particular, this paper empirically examines the influence of four innovation forms (intramural R&D, extramural R&D, product innovation, and process innovation) on firms’ sustainable economic performance, considering the moderating effect of family involvement in management. To test the hypotheses, random-effects regression analyses are applied to a longitudinal sample of 598 Spanish private manufacturing firms throughout the 2006–2015 period. The results show a negative effect of intramural and extramural R&D on sustainable economic performance and a positive effect of process innovation on sustainable economic performance. Moreover, a reinforced relationship between process innovation and sustainable economic performance is also revealed when family involvement in management acts as a moderator. The findings make several contributions to research and practice

Nuevos documentos inéditos y desconocidos de Rubén Darío: sobre "La Isla de Oro", el "Poema del Otoño" y los años de "Mundial"

This article studies and reproduces a group of documents that includes some hand-written and typed texts most likely authored by Rubén Darío, along with others where Darío’s authorship can be easily contested. These documents seem to have originated during the years of Mundial Magazine (1912-1914), and besides the interest for their probably unpublished nature, they also show the cooperation between Darío and his collaborators in the preparation of his original manuscripts right before being sent to the publishers.En este artículo se comenta y reproduce en parte un lote de documentos que incluye unos textos manuscritos y mecanografiados de casi segura autoría dariana y otros de autenticidad más dudosa. Este lote, cuyo origen parece estar en los años de Mundial (1912-1914), además de contener algunos poemas inéditos, incluye otros textos que mostrarían la cooperación entre Darío y sus secretarios o colaboradores en la preparación de los originales inmediatamente antes de ser enviados a la imprenta
