- Previous research has extensively explored the role of anxiety, disgust, guilt, and shame in obsessive-compulsive (OC) symptoms, but few studies have investigated anger and associated vengeful motivations, especially during adolescence, when OC symptoms typically onset. This is unfortunate as anger is a key human emotion linked to various aspects of behaviour. Our aim was to explore how anger and revenge motivations were associated with the most common OC subtypes in adolescents. Participants were 1035 high school students who completed a battery of questionnaires including the Obsessive-Compulsive Inventory-Child Version, the Children's Depression Inventory, the Transgression-Related Interpersonal Motivations Inventory-18 and the State-Trait Anger Expression Inventory for children and adolescents. Even when accounting for different aspects of anger, TRIMs and depression, trait anger (i.e., a stable tendency to experience anger) was uniquely associated with all types of OC symptoms (doubting/checking, obsessing, and ordering). Unique associations were also found between revenge motivation and doubting/checking and obsessing. Our findings show that adolescents with high OC symptoms may experience not only intense anger, but also vengeful feelings and motivations. Future research should examine how anger, vengeful motivations and OC symptoms co-develop over time. Clinicians should be aware that anger and vengeful motivations can be part of the clinical presentation of OCD, which can inform assessment and treatment.

Heterogeneous vesiculation of 2011 El Hierro xeno-pumice revealed by X-ray computed microtomography

- During the first week of the 2011 El Hierro submarine eruption, abundant light-coloured pumiceous, high-silica volcanic bombs coated in dark basanite were found floating on the sea. The composition of the light-coloured frothy material ('xeno-pumice') is akin to that of sedimentary rocks from the region, but the textures resemble felsic magmatic pumice, leaving their exact mode of formation unclear. To help decipher their origin, we investigated representative El Hierro xeno-pumice samples using X-ray computed microtomography for their internal vesicle shapes, volumes, and bulk porosity, as well as for the spatial arrangement and size distributions of vesicles in three dimensions (3D). We find a wide range of vesicle morphologies, which are especially variable around small fragments of rock contained in the xeno-pumice samples. Notably, these rock fragments are almost exclusively of sedimentary origin, and we therefore interpret them as relicts an the original sedimentary ocean crust protolith(s). The irregular vesiculation textures observed probably resulted from pulsatory release of volatiles from multiple sources during xeno-pumice formation, most likely by successive release of pore water and mineral water during incremental heating and decompression of the sedimentary protoliths.

- There is a widening gap between the fast advancement of computational methods for tomographic reconstruction and their successful implementation in production software at various synchrotron facilities. This is due in part to the lack of readily available instrument datasets and phantoms representative of real materials for validation and comparison of new numerical methods. Recent advancements in detector technology have made sub-second and multi-energy tomographic data collection possible (Gibbs et al 2015 Sci. Rep. 5 11824), but have also increased the demand to develop new reconstruction methods able to handle in situ (Pelt and Batenburg 2013 IEEE Trans. Image Process. 22 5238-51) and dynamic systems (Mohan et al 2015 IEEE Trans. Comput. Imaging 1 96-111) that can be quickly incorporated in beamline production software (Gürsoy et al 2014 J. Synchrotron Radiat. 21 1188-93). The x-ray tomography data bank, tomoBank, provides a repository of experimental and simulated datasets with the aim to foster collaboration among computational scientists, beamline scientists, and experimentalists and to accelerate the development and implementation of tomographic reconstruction methods for synchrotron facility production software by providing easy access to challenging datasets and their descriptors.

- The current study evaluates the factor structure of the Disgust Scale–Revised (DS-R) in eightcountries: Australia, Brazil, Germany, Italy, Japan, the Netherlands, Sweden, and the UnitedStates (N = 2,606). Confirmatory factor analysis is used to compare two different models of the DS-R and to investigate the invariance of the factor structure of the DS-R across countries and gender. A three-factor solution consisting of three different but interrelated disgust factors (a 12-item core disgust factor, an 8-item animal-reminder disgust factor, and a 5-item contamination disgust factor) best accounted for the data in all countries except the Netherlands. Relative to the United States, the three-factor solution is invariant in Australia, Brazil, and Japan but not in Germany, Italy, the Netherlands, and Sweden. The three-factor solution is also invariant across gender in most countries. The implications of these cross-cultural findings for promoting a morevalid and reliable assessment of disgust dimensions, as assessed by the DS-R, are discussed.

COGNIT: challenges and vision for a serverless and multi-provider cognitive cloud-edge continuum
- 2023

Ingår i: 2023 IEEE International Conference on Edge Computing and Communications (EDGE). - : IEEE. - 9798350304831 - 9798350304848 ; , s. 12-22

Konferensbidrag (refereegranskat)abstract
- Use of the serverless paradigm in cloud application development is growing rapidly, primarily driven by its promise to free developers from the responsibility of provisioning, operating, and scaling the underlying infrastructure. However, modern cloud-edge infrastructures are characterized by large numbers of disparate providers, constrained resource devices, platform heterogeneity, infrastructural dynamicity, and the need to orchestrate geographically distributed nodes and devices over public networks. This presents significant management complexity that must be addressed if serverless technologies are to be used in production systems. This position paper introduces COGNIT, a major new European initiative aiming to integrate AI technology into cloud-edge management systems to create a Cognitive Cloud reference framework and associated tools for serverless computing at the edge. COGNIT aims to: 1) support an innovative new serverless paradigm for edge application management and enhanced digital sovereignty for users and developers; 2) enable on-demand deployment of large-scale, highly distributed and self-adaptive serverless environments using existing cloud resources; 3) optimize data placement according to changes in energy efficiency heuristics and application demands and behavior; 4) enable secure and trusted execution of serverless runtimes. We identify and discuss seven research challenges related to the integration of serverless technologies with multi-provider Edge infrastructures and present our vision for how these challenges can be solved. We introduce a high-level view of our reference architecture for serverless cloud-edge continuum systems, and detail four motivating real-world use cases that will be used for validation, drawing from domains within Smart Cities, Agriculture and Environment, Energy, and Cybersecurity.
