Efficient Coupling between Dielectric-Loaded Plasmonic and Silicon Photonic Waveguides

The realization of practical on-chip plasmonic devices will require efficient coupling of light into and out of surface plasmon waveguides over short length scales. In this letter, we report on low insertion loss for polymer-on-gold dielectric-loaded plasmonic waveguides end-coupled to silicon-on-insulator waveguides with a coupling efficiency of 79 ± 2% per transition at telecommunication wavelengths. Propagation loss is determined independently of insertion loss by measuring the transmission through plasmonic waveguides of varying length, and we find a characteristic surface-plasmon propagation length of 51 ± 4 μm at a free-space wavelength of λ = 1550 nm. We also demonstrate efficient coupling to whispering-gallery modes in plasmonic ring resonators with an average bending-loss-limited quality factor of 180 ± 8

Affect's Effects: Considering Art-activism and the 2001 Crisis in Argentina

Anxious of straying too far from traditional rational actor models and an assiduous positivism, social movement scholars have displayed a persistent tendency to overlook the specificities of visual tools and aesthetic experience in claim-making and political protest. Often, as a direct consequence, the possibilities for mobilization and the matrices within which action takes place are described and understood in ways that are oversimplified, even distorted. Notably, small steps have been taken to overcome these distortions by building in a theory of affect that reserves a crucial space for the extra-discursive in the study of contentious politics. Extending some of these insights, this article reveals how an affect-informed approach can be particularly illuminating in studies of art-activism. It takes stencil protests from the aftermath of the 2001 crisis in Argentina as a case in point, discussing affects and their effects on porteño street artists. In so doing, it strengthens the case for greater incorporation of affect as a tool for understanding in literatures that deal with questions of framing, art-activism and the possibilities for social change

Synthesis and Characterization of Plasmonic Resonant Guided Wave Networks

Composed of optical waveguides and power-splitting waveguide junctions in a network layout, resonant guided wave networks (RGWNs) split an incident wave into partial waves that resonantly interact within the network. Resonant guided wave networks have been proposed as nanoscale distributed optical networks (Feigenbaum and Atwater, Phys. Rev. Lett. 2010, 104, 147402) that can function as resonators and color routers (Feigenbaum et al. Opt. Express 2010, 18, 25584–25595). Here we experimentally characterize a plasmonic resonant guided wave network by demonstrating that a 90° waveguide junction of two v-groove channel plasmon polariton (CPP) waveguides operates as a compact power-splitting element. Combining these plasmonic power splitters with CPP waveguides in a network layout, we characterize a prototype plasmonic nanocircuit composed of four v-groove waveguides in an evenly spaced 2 × 2 configuration, which functions as a simple, compact optical logic device at telecommunication wavelengths, routing different wavelengths to separate transmission ports due to the resulting network resonances. The resonant guided wave network exhibits the full permutation of Boolean on/off values at two output ports and can be extended to an eight-port configuration, unlike other photonic crystal and plasmonic add/drop filters, in which only two on/off states are accessible

Childhood cross-ethnic exposure predicts political behavior seven decades later: evidence from linked administrative data

Does contact across social groups influence sociopolitical behavior? This question is among the most studied in the social sciences with deep implications for the harmony of diverse societies. Yet, despite a voluminous body of scholarship, evidence around this question is limited to cross-sectional surveys that only measure short-term consequences of contact or to panel surveys with small samples covering short time periods. Using advances in machine learning that enable large-scale linkages across datasets, we examine the long-term determinants of sociopolitical behavior through an unprecedented individual-level analysis linking contemporary political records to the 1940 U.S. Census. These linked data allow us to measure the exact residential context of nearly every person in the United States in 1940 and, for men, connect this with the political behavior of those still alive over 70 years later. We find that, among white Americans, early-life exposure to black neighbors predicts Democratic partisanship over 70 years later.Published versio

Quality in Tourism Literature: A Bibliometric Review

[EN] The literature about quality has experienced an important expansion in the tourism sector in the last decade. This is a result of the importance of quality issues when attempting to maintain and expand sustainable business models for tourism organizations and destinations, which are critical to strengthen competitiveness in the new framework. This relevance has been reflected in the tourism literature, with numerous papers focusing on the topic of quality. Nevertheless, despite its importance, there is a lack of studies and reviews of this literature. In order to overcome this problem, this paper develops a bibliometric and visualization analysis of the literature that examines the topics of tourism and quality together. Specifically, the article studies the 4625 documents on this issue published until the end of 2018 in the Web of Science Core Collection database, by using the co-occurrence of keywords, co-citation, bibliographic coupling, and co-authorship analyses. In addition, the VOSviewer program was used to map the diverse clusters or relationships among the literature. The results showed the trends and impact of this literature, and also the main papers, authors, journals, institutions, and even countries that focus on tourism and quality aspects together. They are useful for researchers and practitioners when dealing with this topic, in order to better understand the situation of this issue and its development.This research was funded by Universitat Politecnica de Valencia, Universitat Jaume I. and The APC was funded by Walailak University.Garrigós Simón, FJ.; Narangajavana-Kaosiri, Y.; Narangajavana, Y.

Marketing, art and voices of dissent: promotional methods of protest art by the 2014 Hong Kong’s Umbrella Movement

Limited research exists around the interrelationships between protest camps and marketing practices. In this paper, we focus on the 2014 Hong Kong protest camps as a context where artistic work was innovatively developed and imaginatively promoted to draw global attention. Collecting and analyzing empirical data from the Umbrella Movement, our findings explore the interrelationships between arts marketing technologies and the creativity and artistic expression of the protest camps so as to inform, update and rethink arts marketing theory itself. We discuss how protesters used public space to employ inventive methods of audience engagement, participation and co-creation of artwork, together with media art projects which aimed not only to promote their collective aims but also to educate and inform citizens. While some studies have already examined the function of arts marketing beyond traditional and established artistic institutions, our findings offer novel insights into the promotional techniques of protest art within the occupied space of a social movement. Finally, we suggest avenues for future research around the artwork of social movements that could highlight creative and political aspects of (arts) marketing theory

Echocardiography practice, training and accreditation in the intensive care: document for the World Interactive Network Focused on Critical Ultrasound (WINFOCUS)

Echocardiography is increasingly used in the management of the critically ill patient as a non-invasive diagnostic and monitoring tool. Whilst in few countries specialized national training schemes for intensive care unit (ICU) echocardiography have been developed, specific guidelines for ICU physicians wishing to incorporate echocardiography into their clinical practice are lacking. Further, existing echocardiography accreditation does not reflect the requirements of the ICU practitioner. The WINFOCUS (World Interactive Network Focused On Critical UltraSound) ECHO-ICU Group drew up a document aimed at providing guidance to individual physicians, trainers and the relevant societies of the requirements for the development of skills in echocardiography in the ICU setting. The document is based on recommendations published by the Royal College of Radiologists, British Society of Echocardiography, European Association of Echocardiography and American Society of Echocardiography, together with international input from established practitioners of ICU echocardiography. The recommendations contained in this document are concerned with theoretical basis of ultrasonography, the practical aspects of building an ICU-based echocardiography service as well as the key components of standard adult TTE and TEE studies to be performed on the ICU. Specific issues regarding echocardiography in different ICU clinical scenarios are then described

Untangling knowledge creation and knowledge integration in enterprise wikis

A central challenge organizations face is how to build, store, and maintain knowledge over time. Enterprise wikis are community-based knowledge systems situated in an organizational context. These systems have the potential to play an important role in managing knowledge within organizations, but the motivating factors that drive individuals to contribute their knowledge to these systems is not very well understood. We theorize that enterprise wiki initiatives require two separate and distinct types of knowledge-sharing behaviors to succeed: knowledge creation (KC) and knowledge integration (KI). We examine a Wiki initiative at a major German bank to untangle the motivating factors behind KC and KI. Our results suggest KC and KI are indeed two distinct behaviors, reconcile inconsistent findings from past studies on the role of motivational factors for knowledge sharing to establish shared electronic knowledge resources in organizations, and identify factors that can be leveraged to tilt behaviors in favor of KC or KI
