Prenent en consideració el paper actual i futur de la intel·ligència artificial en la licitació pública, el present article es centra, des de l’òptica de les directrius de la Llei 15/2022, integral per a la igualtat de tracte i la no-discriminació, en la potencialitat que pot correspondre a la intel·ligència artificial davant la detecció i l’actuació contra les col·lusions en la contractació pública. Dins d’aquest nou dret computacional de la competència o “antitrust 3.0” es detallarà el paper capdavanter que ha assumit l’Autoritat Catalana de la Competència (ACCO) pel que fa a la posada en marxa, en fase experimental, de l’eina informàtica ERICCA, i, en paral·lel, la seva participació activa dins del projecte Computational Antitrust del Stanford Center for Legal Informatics (CodeX).

It is estimated that more than 500 species of insects have been introduced to the Galápagos Islands via human activities. One of these insect invaders is the yellow paper wasp, Polistes versicolor (Olivier) (Hymenoptera: Vespidae), a social wasp native to continental South America. In Galápagos, these wasps are voracious predators of insect larvae, compete with native species for insect prey or for floral resources and are a human nuisance. Wasp suppression methods currently in use are inefficient and attract non-target species, calling for the development of species-specific attractants that can be used in baits to lure and kill wasps. To evaluate the potential for using wasp semiochemicals in baits, we determined the biochemical composition of the head, thorax, Dufour’s and venom glands of P. versicolor foragers via gas chromatography/mass spectrometry (GC/MS). Male and female wasps were tested for behavioral responses to body segment extracts from both sexes. Female body extracts consistently elicited more behavioral responses in both male and female wasps than male extracts. Females reacted to female head, thorax and abdomen (the Dufour’s and venom glands are located in the abdomen) extracts, whereas males reacted significantly to female head and thorax extracts. One male body extract, the head, elicited two significant behaviors: female wasps groomed more often, and males touched the filter paper more often compared to the blank control. Head extracts consistently changed the behavior of female and male wasps and, together with female thorax extracts, have potential as species-specific lures for yellow paper wasps. Heads were mainly composed of hydrocarbon lipids and oleamide, a ligand for odorant-binding proteins. The thorax consisted of fatty aldehydes, long-chain alkanes and fatty amide lipids. Field trials of blends of these compounds in high wasp density areas of Galápagos are the next step to confirm if any of these compounds are attractive to P. versicolor.

ABSTRACT Coronary artery calcification is probably the main determinant of the poor outcome of percutaneous coronary interventions and is associated with higher rates of adverse events. There are currently different balloon or specific device-based plaque modification techniques available. Knowing their characteristics and proper use is key for the optimal treatment of calcified lesions. This position paper—promoted by the Interventional Cardiology Association of the Spanish Society of Cardiology (ACI-SEC)—describes existing plaque modification techniques currently available and proposes an algorithm for the management of calcified lesions.

Four organic solid wastes (coffee grounds, ground nut shell, paper money sewage sludge and cork powder) have been investigated as bloating inducing agents in lightweight aggregate (LWA) manufacturing when mixed in small proportions (2.5 wt.%) with three types of clays. The pellets obtained were fired in a rotary kiln at the maximum feasible temperature for 4 min. A similar impact was observed both in the working conditions and in the properties of the LWAs, showing that the differences between said residues are not as decisive as those of the clays to which they are added. The organic wastes have played a crucial role in achieving reducing conditions inside the aggregate. Thus, their addition has led to substantial improvements both from an operational point of view, lowering the working temperature, and from a technological perspective, favoring bloating and the development of a highly porous and lightweight structure. Leachate studies have shown that the LWAs meet the regulatory limits. The outcomes of this investigation show that, in line with the precepts of the Circular Economy, the recovery of organic wastes of different nature can have a place in the production of environmentally friendly LWAs. Resumen: Se han investigado cuatro residuos sólidos orgánicos (posos de café, cáscara molida de frutos secos, lodos de depuradora de papel moneda y polvo de corcho) como agentes expansivos en la fabricación de áridos ligeros (LWAs) al mezclarse en pequeñas proporciones (2,5 wt.%) con tres tipos de arcillas. Los pellets conformados se han cocido en un horno rotatorio a la máxima temperatura viable durante 4 min. Se observó un impacto similar tanto en las condiciones de trabajo como en las propiedades de los LWAs, mostrando que las diferencias entre dichos residuos no son tan influyentes como las de las arcillas a las que se añaden. El componente orgánico ha jugado un papel crucial en la consecución de las condiciones reductoras dentro del árido. Así, su adición ha supuesto mejoras sustanciales tanto desde el punto de vista operativo, reduciendo la temperatura de trabajo, como desde una perspectiva tecnológica, favoreciendo la expansión y el desarrollo de una estructura altamente porosa y ligera. Por otro lado, los LWAs obtenidos cumplirían con los límites reglamentarios de lixiviación de metales pesados. Se demuestra que la valorización de residuos orgánicos de distinta naturaleza puede tener cabida en la producción de LWAs respetuosos con el medio ambiente.

Objective: To provide a working guide which facilitates the accuracy, transparency, and usefulness for academics and practitioners of case report papers as an article type which are fit for publishing in impact journals. In this way, we aim to increase the use and dissemination of recommendations in aid of the writing and publication of case study and action research. Theoretical framework: A case report paper presents a story in narrative form and includes current individual or organisational concerns, situational diagnoses, interventions, outcomes including adverse events, and follow-up. The narrative should include a discussion of the rationale for any conclusions and lessons learned. Method: We analysed the prevalence of these type of articles in publications as indexed in Web of Science (WOS) and in Scopus; we explain how we customised the case report guidelines (CAse REport or CARE) to optimise them for the scientific field of Management focussing particularly on Operations Management and Human Resources Management. We shared for discussion and feedback the adapted proposal among a group of academics and professionals in the field of Management. Outcomes/Implications: Robust reporting guidelines help to improve research performance, reduce bias risk, provide information on the implementation of management practices, support the training of management professionals, and enable informed editorial decisions by journal editors and reviewers.
