A multi-layered performance analysis for cloud-based topic detection and tracking in Big Data applications

In the era of the Internet of Things and social media; communities, governments, and corporations are increasingly eager to exploit new technological innovations in order to track and keep up to date with important new events. Examples of such events include the news, health related incidents, and other major occurrences such as earthquakes and landslides. This area of research commonly referred t

Assessment of Competence in EVAR Procedures : A Novel Rating Scale Developed by the Delphi Technique

OBJECTIVE/BACKGROUND: To develop a procedure specific global rating scale for assessment of operator competence in endovascular aortic repair (EVAR).METHODS: A Delphi approach was used to achieve expert consensus. A panel of 32 international experts (median 300 EVAR procedures, range 200-3000) from vascular surgery (n = 21) and radiology (n = 11) was established. The first Delphi round was based o

DN Debatt ”Partier, lova väljarna att avstå från oetiska digitala metoder”

DN DEBATT 22/3. Det svenska valet hotas av digitala påverkansoperationer där falska robot-konton och så kallade ”dark ads” kan dränka det politiska samtalet. Vi utmanar nu riksdagspartierna: Ge ett enkelt löfte till väljarna om att ni inte kommer att använda er av oetiska metoder på nätet, skriver Jonas Andersson Schwarz, Stefan Larsson och Anders Mildner.

On Giddens: Interpreting Public Relations through Anthony Giddens’s Structuration and Late Modernity Theories

Public relations was historically an isolated theoretical field and an, in practice, undeveloped organizational publicity function for many years. From the perspective of strategy research, theory as well as practice has traditionally been dominated by traditional, rational, linear and functionalistic approaches (Whittington, 2000). The foundation in functionalism has led researchers to focus on e

Experimentell fysik

I denna bok utgår författarna både från experimentalfysikens varför och experimentalfysikens hur. De ger bakgrunder och visioner tillsammans med handfasta kunskaper inom den experimentella fysiken. Boken är främst avsedd för teknologer, naturvetare och lärare. Men framställningen är medvetet utformad för att också kunna nå utanför denna krets, och bokens första halva kräver inga speciella matemati

Researchers’ online visibility : Tensions of visibility, trust and reputation

Purpose – The purpose of this article is to understand what role researchers assign to online representations on the new digital communication sites that have emerged, such as Academia, ResearchGate or Mendeley. How are researchers’ online presentations created, managed, accessed and, more generally, viewed by academic researchers themselves? And how are expectations of the academic reward system

Air pollution online : Everyday environmental information on the social media site Sina Weibo

Purpose: This study explores how information on air pollution is shaped online on an everyday basis, with a particular emphasis on digital devices and digital representations as constitutive of environmental information practices. Furthermore, this research highlights an understudied aspect of air pollution – the digital flow of multimodal representations that citizens encounter and produce in the

Allmänhetens uppfattning kring användandet av övervakningskameror på gator och torg, augusti 2017

Under andra veckan av augusti genomfördes 1000 telefonintervjuer på temat allmänhetens attityd till användandet av övervakningskameror på gator och torg. 90% av allmänheten svarade positivt när de ställdes frågan ”Vad tycker du om övervakningskameror på allmän plats?” uppdelat på 49% som ställde sig mycket positiva och 41% som ställde sig ganska positiva. Vidare ansåg 72% av de tillfrågade att det

New biobased non-ionic hyperbranched polymers as environmentally friendly antibacterial additives for biopolymers

The aim of this research was to develop new biobased non-ionic polymeric additives with significant bacterial inhibition and low leaching potential, so that they can be used to produce biopolymer materials for various applications such as biomedical devices, surgical textile, or food packaging. Two new non-ionic hyperbranched polymers (HBPs) were prepared by a facile solvent-free polymerization of

Implementation of knowledge-based palliative care in nursing homes and pre-post post evaluation by cross-over design: a study protocol

BackgroundThe demography of the world is changing as the population is ageing. Because of this change to a higher proportion of older people, the WHO has called for improved palliative care for older persons. A large number of all deaths in the industrialised world occur while older people are living in nursing homes and therefore a key question becomes how the principles of palliative care can be

Mapping the plastics system and its sustainability challenges

Plastics are versatile materials with environmental, technical, economical and societal benefits, however plastics also contribute negatively to the environment and climate. Put in numbers around 4% of the fossil oil and gas is used as feedstock for plastics while another 4% is used for providing energy for the manufacturing of plastics. Many initiatives on reducing the negative effects of plastic

Google as a political subject : the right to be forgotten debate 2014-2016

PurposeThe aim of the study is to create knowledge on how Google and Google search are discursively constructed as a political subject suitable or not suitable for governing in the debate regarding the Right to be Forgotten ruling (RTBF). Design/Methodology/Approach28 texts are analysed using a Foucauldian discourse analysis focusing on political problematisations in the media and in blogs. Find

Cyclone Activity in the Arctic From an Ensemble of Regional Climate Models (Arctic CORDEX)

The ability of state-of-the-art regional climate models to simulate cyclone activity in the Arctic is assessed based on an ensemble of 13 simulations from 11 models from the Arctic-CORDEX initiative. Some models employ large-scale spectral nudging techniques. Cyclone characteristics simulated by the ensemble are compared with the results forced by four reanalyses (ERA-Interim, National Centers for

Advances in SAR-ISAR blending

Radar signature measurements of targets with or without camouflage in different backgrounds using airborne SAR are complex and expensive. Measurements at many orientations as well as illumination angles have to be performed for each target for completeness. A more efficient solution is to use ground based ISAR measurements of the desired targets and then blend these images into measured SAR scenes

Time between anterior cruciate ligament injury and reconstruction and cartilage metabolism six-months following reconstruction

Background: To determine the association between time from injury to ACL reconstruction (TimeInjury-ACLR) and biochemical markers of cartilage metabolism and inflammation six months following ACL reconstruction (ACLR). Methods: Individuals with a unilateral ACL injury were enrolled at initial presentation in the orthopedic clinic; blood was collected six months following ACLR. Enzyme-linked immuno

Multicenter study of retrograde open mesenteric artery stenting through laparotomy for treatment of acute and chronic mesenteric ischemia

Objective: Retrograde open mesenteric stenting (ROMS) through laparotomy was introduced as an alternative to surgical bypass in patients with acute mesenteric ischemia (AMI). The purpose of this study was to evaluate the indications and outcomes of ROMS for treatment of AMI and chronic mesenteric ischemia. Methods: We reviewed the clinical data and outcomes of all consecutive patients treated by R
