Frailty Tools for Assessment of Long-term Prognosis After Acute Coronary Syndrome
2020
Objective: To evaluate the 5 components of the Fried frailty phenotype (self-reported unintentional weight loss, physical activity questionnaire, gait speed, grip strength, and self-reported exhaustion) for long-term outcomes in elderly survivors of acute coronary syndrome. Methods: A total of 342 consecutive patients (from October 1, 2010, to February 1, 2012) were included. The 5 components of the Fried score and albumin concentration, as malnutrition index, were assessed before hospital discharge. Patients were followed up until April 2020 (median follow-up, 8.7 years). The end point was postdischarge all-cause mortality. Results: Mean ± SD age was 77±7 years and mean ± SD Fried score wa…
Toward a refined conceptualization of IS discontinuance : Reflection on the past and a way forward
2020
Interest in studying information systems discontinuance has been increasing lately, yet there is no consensus on what it means. To improve the situation, we conduct a comprehensive review of current literature on IS discontinuance and identify 55 studies published during 1991–2017 that specifically focus on the topic. Our conceptual analysis disentangles the process, content, and context of the phenomenon, revealing that over the course of a typical IS lifecycle, IS discontinuance may materialize at least in five distinct forms: rejection, regressive discontinuance, quitting, temporary discontinuance, and replacement. After elaborating their distinctions, we discuss their theoretical, metho…
The Actual Adoption and Use of Mobile Apps : The Case of a Higher Education Context
2020
Mobile applications have gained wide acceptance in several sectors, including eCommerce and education. In higher education, mobile apps are being used not only for mobile learning but also for creating smart campus environments in which physical campuses are augmented with digital services. Mobile apps for smart campus initiatives usually have several features that students and educators are expected to adopt and use. However, although prior studies have investigated the adoption of mobile apps, most of such studies are on the user's intention to use or continue using mobile apps, leaving gaps in our understanding of how actual use occurs. Drawing on a case study of a mobile app for a smart…

Learning in sport : from life skills to existential learning
2020
Youth sport is habitually promoted as an important context for learning that contributes to a person’s broader development beyond sport-specific skills. A growing body of research in this area has operated within a life skills discourse that focuses on useful, positive and decontextualised skills in the production of successful and adaptive citizens. In this paper, we argue that the ideological discourse of life skills, underpinned by ideas about sport-based positive youth development, has unduly narrowed the research on learning in sport to only what is deemed functional, teachable, and economically productive. After considering the problems associated with the currently dominant life skil…
Geochemistry, zircon U–Pb ages and Lu–Hf isotopes of early Paleozoic plutons in the northwestern Chinese Tianshan: Petrogenesis and geological implic…
2013
Abstract The northwestern Chinese Tianshan is a key part of the southern Central Asian Orogenic Belt. Voluminous arc-related igneous rocks in this region have recorded the opening and closure of several oceanic basins that may represent southern branches of the Paleo-Asian Ocean. We have conducted geochemical, geochronological and Hf-in-zircon isotopic studies on mafic and felsic intrusive rocks in the northwestern Chinese Tianshan to provide important clues for the evolution of the Junggar Ocean and to understand the early Paleozoic crustal growth in the Central Asian Orogenic Belt. The mafic plutons are composed of metagabbro (453.8 ± 2.0 Ma) and fine-grained diorite (461.1 ± 2.0 Ma). The…
Uniform continuity of quasiconformal mappings and conformal deformations
2008
We prove that quasiconformal maps onto domains satisfying a suitable growth condition on the quasihyperbolic metric are uniformly continuous even when both domains are equipped with internal metric. The improvement over previous results is that the internal metric can be used also in the image domain. We also extend this result for conformal deformations of the euclidean metric on the unit ball of R n \mathbb {R}^n .
An immune system model in discrete time based on the analogy with the central nervous system
1988
Jerne's model for the immune system formulated in terms of a neural network recently proposed by Weisbuch and Atlan is generalized to interactions with continuous coupling coefficients. It is shown that even the extended model can be solved analytically without the aid of computer simulations and exhibits one additional attractor, which corresponds to a configuration with high concentrations of active killer cells eventually causing death of the organism.
Modeling wave propagation in elastic solids via high-order accurate implicit-mesh discontinuous Galerkin methods
2022
A high-order accurate implicit-mesh discontinuous Galerkin framework for wave propagation in single-phase and bi-phase solids is presented. The framework belongs to the embedded-boundary techniques and its novelty regards the spatial discretization, which enables boundary and interface conditions to be enforced with high-order accuracy on curved embedded geometries. High-order accuracy is achieved via high-order quadrature rules for implicitly-defined domains and boundaries, whilst a cell-merging strategy addresses the presence of small cut cells. The framework is used to discretize the governing equations of elastodynamics, written using a first-order hyperbolic momentum-strain formulation…
