Impact of strategic capabilities on digital transformation success and firm performance: theory and empirical evidence
What is needed for organisations to succeed in digital transformation, and what is its advantage? Motivated by the ongoing high amount of failing digital transformations, this study identifies necessary predictors and ...
Pilot Ionosonde Network for Identification of Traveling Ionospheric Disturbances
Traveling ionospheric disturbances (TIDs) are the ionospheric signatures of atmospheric gravity waves. Their identification and tracking is important because the TIDs affect all services that rely on predictable ionospheric ...
An overview of methodologies for real-time detection, characterisation and tracking of traveling ionospheric disturbances developed in the TechTIDE project
The main objective of the TechTIDE project (warning and mitigation technologies for travelling ionospheric disturbances effects) is the development of an identification and tracking system for travelling ionospheric ...
Improved characterization and modeling of equatorial plasma depletions
This manuscript presents a method to identify the occurrence of Equatorial Plasma Bubbles (EPBs) with data gathered from receivers of Global Navigation Satellite System (GNSS). This method adapts a previously existing ...
The International Reference Ionosphere Model: A Review and Description of an Ionospheric Benchmark
This paper is a review of the International Reference Ionosphere (IRI) project and model. IRI is recognized as the official standard for the Earth's ionosphere by the International Standardization Organization, the ...
Multi-instrument detection in Europe of ionospheric disturbances caused by the 15 January 2022 eruption of the Hunga volcano
The 15 January 2022 eruption of the Hunga volcano provides a unique opportunity to study the reaction of the ionosphere to large explosive events. In particular, this event allows us to study the global propagation of ...
Spanish validation of the Modified Weight Bias Internalization Scale (WBIS-M) for adolescents
Purpose Weight Bias Internalization (WBI) is pervasive and potentially damaging for health. Little is known about WBI in youth. As negative effects of WBI have been observed when controlling for BMI, measures that allow ...
Women's body dissatisfaction, physical appearance comparisons, and Instagram use throughout theCOVID-19 pandemic: A longitudinal study
Objective: This study aimed to determine the evolution of Instagram use, body dis-satisfaction and physical appearance comparisons throughout the coronavirusdisease-2019 (COVID-19) pandemic, and to explore whether there ...
Assessing Motivational Stages and Processes of Change for Weight Management Around Bariatric Surgery: a Multicenter Study
Introduction/purpose: The assessment of the patients' motivation as a predictor of behavioral change via five stages (pre-contemplation, contemplation, preparation, action, and maintenance) and four processes (emotional ...
The impact of COVID-19 lockdown on social network sites use, body image disturbances and self-esteem among adolescent and young women
Objective This study aimed to determine the impact of COVID-19 lockdown on social network sites (SNS) use and to explore whether SNS use is associated with body image disturbances and low self-esteem. Methods A total ...
Eating Disorder Symptoms in Elite Spanish Athletes: Prevalence and Sport-Specific Weight Pressures
We determined the prevalence of eating disorder (ED) symptoms among elite Spanish athletes from a broad range of sports and levels of competition and examined the associations between the presence of symptoms and perceived ...
3D Printing of Silicone Organogel Elastomers for Structured Soft Biomaterials
Creating customizable soft medical implants and devices tailored to patient-specific anatomy represents a significant challenge in healthcare, requiring 3D-printable materials with viscoelastic properties similar to those ...
A comprehensive fatigue analysis of high performance polyetherimide parts fabricatedusing extrusion-based additive manufacturing
This paper investigates the fatigue behavior of high-performance polyetherimide components manufactured via MEX-AM, focusing on the influence of key process parameters. Thirty configurations were tested under four load ...
From Françafrique to Chinafrica? Ecologically unequal exchange, neocolonialism, and environmental conflicts in Africa
Africa stands out as the continent where the legacies of colonialism and the ongoing dynamics of neo- and post-colonialism are felt most profoundly. In its role as the primary global supplier of raw materials, and with the ...
Animation toolkit based on a database approach for reusing motions and models
As animations become more readily available, simultaneously the complexity of creating animations has also increased. In this paper, we address the issue by describing an animation toolkit based on a database approach for ...
Generating animated paper pop-ups from the motion of articulated characters
Pop-up books are fascinating books comprised of paper pieces that pop out when opened to form interesting three-dimensional structures. But more than just reproducing 3D shapes, pop-up artists also use the movement of the ...
Achieving 17-4 PH parts with comparable performance to high-investment technologies through a multivariable Doehlert design optimization and material extrusion
Purpose: This study aims to optimize Metal Additive Manufacturing (MAM) via Material Extrusion (MEX) using desktop equipment to produce high-performance 17-4 PH stainless steel parts. This research seeks to address the ...
Surface and contour-preserving origamic architecture paper pop-ups
Origamic architecture (OA) is a form of papercraft that involves cutting and folding a single sheet of paper to produce a 3D pop-up, and is commonly used to depict architectural structures. Because of the strict geometric ...
Visualizing animation databases
We consider a repository of animation models and motions that can be reused to generate new animation sequences. For instance, a user can retrieve an animation of a dog kicking its leg (in air) and manipulate the result ...
Automatic Paper Sliceform Design from 3D Solid Models
A paper sliceform or lattice-style pop-up is a form of papercraft that uses two sets of parallel paper patches slotted together to make a foldable structure. The structure can be folded flat, as well as fully opened ...
