Socio-Cultural Power Dynamics and Coping Functions: A Narrative Case Report of a Female Paralympian
2012
Purpose: This case study explores the lived experiences of an elite female Paralympic powerlifting athlete. The focus is on restrictions and coping responses employed to manage the daily hassles within the cultural and ethnic requirements for achieving athletic excellence. Methods: With an unstructured interview, the narrative was acquired which ranged to a total of 75 minutes (approx) and 20 single spaced pages. The data was analyzed using Foucauldian discourse analysis in conjuncture to feminist poststructuralist theory. Results: The results highlight the issues relating to femininity, culture and ethnicity with regard to athletic career. The analysis elicits extracts from the narrative t…
Next Generation Home Sharing: Disrupting Platform Organizations with Blockchain Technology and the Internet of Things?
2020
During the last decade, the sharing economy has given birth to a number of market mediators, which have grown to become the world’s most valuable companies. Centralized sharing platforms like Uber, Didi Chuxing, and Airbnb have transformed several traditional industries. However, with the rise of the blockchain technology, some voices predict that these platform companies will soon be at risk of being disrupted themselves. In this chapter, we address the question of whether blockchain technology has given birth to a new breed of sharing economy platforms that can challenge the incumbents’ business models. We identify five different stages of the application of blockchain technology in emerg…
Absence of structure in the $^{20,22}$Ne + $^{118}$Sn quasi-elastic barrier distribution
2005
Abstract Motivated by the extreme deformation parameters of the projectile, we have measured quasi-elastic scattering for 20 Ne + 118 Sn. In contrast to calculations based on known collective states, the experimental barrier distribution is structureless. A comparison with the system 22 Ne + 118 Sn shows that this smoothing is unlikely to be due to nucleon- or α -transfer channels, and is more likely to be due to coupling to many other weak channels.
Chapter 13 : Marshalling Resources and Dynamic Capabilities to Overcome Innovative Barriers and Foster Creativity in the Service Sector
2013
Understanding the economic implication of creative individuals and firms is at the heart of the new economy and of related fields such as the economics of knowledge, the economics of science and innovation management. This book brings together a panel of theoretical and empirical contributions which address the generation of creative ideas and their transformation into products and services by firms or universities, as well as the interplay of those organizations in networks and markets. The word 'creativity' has been used a great deal recently in relation to efforts to recover from the global financial crisis and re-launch economic activity. Little has been added to explain how and why an …
1H NMR study of dynamical inequivalence of cations in [C(NH2)3]3Sb2Cl9
2001
Abstract The proton NMR second moment and spin–lattice relaxation time have been studied for polycrystalline tris-guanidinium nonachlorodiantimonate(III) in a wide temperature range. The C 3 reorientation of two types of the cations, hindered by very different potential barriers (20.5 and 54.5 kJ/mol) has been revealed. An unusually large dynamical inequivalence of two cations evidently reflects their different crystalline environments.
Understanding cultural barriers and opportunities for developing new apprenticeship programmes
2020
There is increasing interest in many countries in training models that are practice-oriented and correspond to the needs of the labour market. The new Spanish dual system of apprenticeship (FP Dual) for teaching and learning was first implemented in the Valencia Community in 2012. Although FP Dual enjoys considerable support from institutions and from politicians who believe it has the potential to reduce youth unemployment, the dual system is still in a pilot stage. This report is based on research based in Valencia, to explore the cultural and organisational norms and the barriers and opportunities these afford to introducing apprenticeship. The research included interviews with different…
A DC and small signal AC model for organic thin film transistors including contact effects and non quasi static regime
2017
Abstract We present a compact model for the DC and small signal AC analysis of Organic Thin Film Transistors (OTFTs). The DC part of the model assumes that the electrical current injected in the OTFT is limited by the presence of a metal/organic semiconductor junction that, at source, acts as a reverse biased Schottky junction. By including this junction, modeled as a reverse biased gated diode at source, the DC model is able to reproduce the scaling of the electrical characteristics even for short channel devices. The small signal AC part of the model uses a transmission line approach in order to compute the impedances of the channel and parasitic regions of the device. The overlap capacit…

Valuation of Barrier Options in a Black-Scholes Setup with Jump Risk
1999
This paper discusses the pitfalls in the pricing of barrier options approximations of the underlying continuous processes via discrete lattice models. These problems are studied first in a Black-Scholes model. Improvements result from a trinomial model and a further modified model where price changes occur at the jump times of a Poisson process. After the numerical difficulties have been resolved in the Black-Scholes model, unpredictable discontinuous price movements are incorporated.
Interpretación social y accesibilidad. Una propuesta de conexión disciplinar
2020
El objetivo de este estudio es ofrecer argumentos para entender la actividad propia de la interpretación social como parte del dominio genérico de la accesibilidad. Al hacerlo no ampliamos en realidad el concepto de accesibilidad, sino que reforzamos aquello que justifica el uso de este término, para diferenciar una parcela de actividad dentro de la práctica general de la traducción y la interpretación. Con el tema de la accesibilidad sucede que se ha manejado una etiqueta sin una delimitación conceptual previa de lo que se pretende designar por medio de ella. En este estudio nos ocupamos brevemente de esta tarea de aproximación conceptual, con el objetivo de incluir bajo el abanico de las …
