Querns and Mills in Mediterranean Antiquity : Tradition and Innovation during the First Millennium BC
(Ausonius Éditions, 2023-12-22) Alonso, Natàlia; Anderson, Timothy J.; Jaccottey, Luc
After thousands of years of exclusively grinding with a to and fro motion, several new types of mills appeared and evolved in the Mediterranean during the last millennium BC. The first centuries of this millennium saw the development of a variety of new forms for both the upper and lower stones of these early back and forth querns. Yet the main changes and innovations came later, around the middle of the millennium, with the introduction of new types of mills including the manual rotary quern, the hopper mill and the Iberian rotary pushing mill. Although the historical circumstances of this period differ between the Eastern and Western Mediterranean, these changes emerged precisely in the second half of this millennium, a timeframe characterised by a technological interaction, or lack of, between the different cultures of the Mediterranean world. The new milling systems introduced during this period represent a turning point in the history of processing cereals and other materials. However, many questions as to the causes of the introduction and evolution of these mills and their socio-economic repercussions remain unanswered. The findings of the studies in these proceedings therefore represent modest but necessary advances in this vast and compelling field of research.

La maternidad en fuera de campo en las dramedias españolas (2018-2021)
(Universidad de Antioquia, 2023-12-31) Visa Barbosa, Mariona; Torres Hortelano, Lorenzo J.; Menéndez Menéndez, María Isabel
España es el segundo país europeo con la tasa de natalidad más baja y también el segundo en el que las mujeres posponen más su maternidad. Teniendo en cuenta este contexto, este artículo analizó cómo se construye el imaginario de la maternidad en seis dramedias españolas contemporáneas, distribuidas por las plataformas de vídeo bajo demanda. En primer lugar, se realizó un análisis de contenido cuantitativo y cualitativo para observar la presencia de procesos relativos a la reproducción, los objetivos de las mujeres y la pluralidad en la representación de las figuras maternas. En segundo lugar, se implementó una metodología cualitativa de análisis textual que estudió la puesta en escena de las primeras y las últimas apariciones de las protagonistas en la serie para observar la evolución de su arco narrativo. A partir de esto se concluyó: 1) que las mujeres protagonistas de las dramedias españolas tienen gran conocimiento y control de sus procesos reproductivos, y que aunque ser madres no es una prioridad para ellas, cuando lo es, se apartan de los estereotipos tradicionales; y 2) en estas ficciones, las decisiones sobre la maternidad son representadas como fruto de impulsos individuales, lo que destaca la ausencia de compromiso con el contexto social actual. El artículo demuestra que las dramedias actuales marcan un avance respecto a la representación en las ficciones españolas de la primera década del siglo XX, si bien se observa un menor diálogo con la realidad social que en las dramedias anglosajonas contemporáneas.

Gillnet selectivity for three freshwater alien invasive fish species in a long-term monitoring scenario
(MDPI, 2022-05-19) Sánchez-González, Jorge Rubén; Casals i Martí, Frederic
Gillnet selectivity is poorly understood for most freshwater fish species, particularly for invasive alien species. However, their use to determine mesh selectivity could be essential for establishing management measures, such as the selective removal of exotic invasive species. This study aims to the assess size selectivity of exotic invasive species in a restored lentic freshwater ecosystem. Therefore, we analysed gillnet size selectivity based on experimental fishing trials performed by using multimesh gillnets. Twice a year, for 8 years, multimesh nylon gillnets were set up in the Estany d'Ivars i Vila-sana, a restored shallow lake in Catalonia (NE Iberian Peninsula). We caught 4105 individuals belonging to three widely distributed freshwater fish species¿3583 pikeperches (Sander lucioperca (Linnaeus, 1758)), 115 common roaches (Rutilus rutilus (Linnaeus, 1758)) and 407 common carps (Cyprinus carpio, Linnaeus, 1758). The SELECT method was applied to fit six different gillnet selectivity uni- and bimodal models. As a result, bi-lognormal provides the best fit for the three species. This is in line with previous studies that found size-frequency data skewed to the right or to multimodal models when high numbers of fish are captured. These results provide the essential information required for fish community management with the presence of these invasive alien species.

Educational interventions and identification of risk factors to prevent and reduce peritonitis in peritoneal dialysis: A scoping review
(Wiley, 2024-02-20) Fernàndez Labadía, Elena; Masot, Olga; Tejero Vidal, Lorena Lourdes; Botigué, Teresa; Bielsa Gracia, Sara
Background: Peritonitis is a common and serious complication of peritoneal dialysis and is one of the main causes of peritoneal dialysis technique failure and long-term hemodialysis conversion. Objectives: The aim of the review was to identify and clarify peritonitis risk factors and learn about strategies employed at international level to prevent and reduce the occurrence of peritoneal dialysis associated infections and their complications. Design: A scoping review. Participants: Adults in pertitoneal dialysis. Measurements: The methodology framework of Arksey and O'Malley and PRISMA for Scoping Reviews guidelines were applied. A search was conducted of PubMed, Scopus and CINAHL using terms to identify peritoneal dialysis -associated risk factors and interventions carried out for the prevention and reduction of peritonitis in adult persons living at home. Results: The 17 studies selected were based on work carried out in nine different countries. Eleven articles analysed modifiable risk factors (low educational level, being a foreigner and low adherence to aseptic technique) and non-modifiable risk factors (age and comorbidities) that predispose to peritonitis in peritoneal dialysis. The other six studies applied an intervention to improve the prevalence of peritonitis considering educational practices adapted to patient characteristics and the application of retraining. Conclusions: Personalised patient training and the identification of risk factors for peritonitis are key to reducing complications and enhancing the survival of peritoneal dialysis patients and the effectiveness of the technique.
