The Role of Religiosity in Symptom Expression of Advanced Cancer Patients

2021

Aim: The aim of this study was to assess the religious pattern and its impact on symptom expression in patients with advanced cancer. Methods: A consecutive sample of advanced cancer patients screened at admission to palliative care. Standard epidemiological data were recorded. Patients were asked about their religious beliefs, the degree of social relationship to existing religions, the role of religion in their life, and the frequency of their prayer. The Edmonton Symptom Assessment Scale (ESAS) and Hospital Anxiety Depression scale (HADS) were assessed. Results: Two-hundred-eighty-three patients were screened. Age and gender were found to be independently correlated with religious belief…

Using protection motivation theory in the design of nudges to improve online security behavior

2019

Abstract We conducted an online experiment (n = 2024) on a representative sample of internet users in Germany, Sweden, Poland, Spain and the UK to explore the effect of notifications on security behaviour. Inspired by protection motivation theory (PMT), a coping message advised participants on how to minimize their exposure to risk and a threat appeal highlighted the potential negative consequences of not doing so. Both increased secure behavior – but the coping message significantly more so. The coping message was also as effective as both messages combined, but not so the threat appeal. Risk attitudes, age and country had a significant effect on behavior. Initiatives seeking to promote se…

Query expansion and semantic visualization in information system cooperations : methods and tools for information retrieval

2010

This thesis presents approaches and tools for information retrieval. Our work is part of a cooperation system based on ontologies called OWSCIS (Ontology and Web Service based Cooperation of Information Sources). We treat the problem of information retrieval by providing an enrichment method called QUEXME (QUery EXpansion MEthod) of queries based on analysis of user behavior and using the concept importance notion with regards to query. We also discussed the problem of visualization in the OWSCIS system offering a architecture of service visualization. It is composed of three modules: the request, enrichment and results. The approaches proposed in this thesis have been prototyped and the te…

Fourth Workshop on using Emerging Parallel Architectures

2012

AbstractThe Fourth Workshop on Using Emerging Parallel Architectures (WEPA), held in conjunction with ICCS 2012, provides a forum for exploring the capabilities of emerging parallel architectures such as GPUs, FPGAs, Cell B.E., Intel M.I.C. and multicores to accelerate computational science applications.

Toward Unified Control of Networks of Switches and Sensors Through a Network Operating System

2018

Wireless sensor networks (WSNs) are an integral part of an Internet of Things (IoT) ecosystem. In fact, a typical IoT service deployment considers an integrated network of switches and sensors (as well as actuators). In order to manage this heterogeneous network infrastructure, the use of software defined networking (SDN) technologies is anticipated. However, existing SDN-enabling technologies consider only isolated networks and there has been no concrete solution that treats the whole network in a unified way. In this paper, a network operating system is proposed as a way to address the above issue. Starting from the open network operating system, which currently supports only OpenFlow net…

Wireless MAC Processor Networking: A Control Architecture for Expressing and Implementing High-Level Adaptation Policies in WLANs

2013

The current proliferation of unplanned wireless local area networks (WLANs) is creating the need for implementing different adaptation strategies to improve network performance under mutating and evolving interference scenarios. In this article, we envision a new solution for expressing and implementing high-level adaptation policies in WLANs, in contrast to the current approaches based on vendor-specific implementations. We exploit the hardware abstraction interface recently proposed by the wireless medium access control (MAC) processor (WMP) architecture and some flow-control concepts similar to the Openflow model for defining MAC adaptation policies. A simple control architecture for dis…

Enterprise architecture operationalization and institutional pluralism: The case of the Norwegian Hospital sector

2021

Enterprise architecture (EA) is a systematic way of designing, planning, and implementing process and technology changes to address the complexity of information system (IS) landscapes. EA is operationalized when architecture visions move towards realization through concrete projects. We report a case study on the dynamics of operationalizing EA in the Norwegian hospital sector by exploring different EA project trajectories. Our empirical context is an institutionally pluralistic setting where multiple logics coexist. We show that the distinct logic of EA is added to the institutional context and we find that tensions among existing medical, technical, and managerial logics and EA principle…

Is displacement possible without language? Evidence from preverbal infants and chimpanzees

2013

Is displacement possible without language? This question was addressed in a recent work by Liszkowski and colleagues (Liszkowski, Schafer, Carpenter, & Tomasello, 2009). The authors carried out an experiment to demonstrate that 12-month-old prelinguistic infants can communicate about absent entities by using pointing gestures, while chimpanzees cannot. The main hypothesis of their study is that displacement does not depend on language but is, however, exclusively human and instead depends on species-specific social-cognitive human skills. Against this hypothesis, we will argue that a symbolic representation is needed to intentionally communicate absence and that this symbolic representa…

Constructing the Centre from the Periphery

2003

During recent decades, scientific activity in the Spanish Enlightenment has attracted the attention of many historians of science. The policies of enlightened governments have been regarded as an important step in the process of modernisation of eighteenth-century Spanish society. At the beginning of that century, a new Bourbon dynasty was established in Spain and its policies have been regarded — mainly by conservative historians — as an attempt to introduce “foreign” ideas and practices into Spain. These policies have also been considered as a major effort to “modernise” a supposedly traditionalist country isolated from the rest of Europe and under the control of the powerful Catholic Chu…
