This new species belongs to the Amaryllididae family as defined by Lowry and Stoddart (2002). This family includes two subfamilies: the Vijayiinae and the Amaryllidinae. The determination of the genera belonging to the Vijayiinae may be sometimes difficult with the key families given by these authors. However, this new species has the whole characters defined in the diagnosis of the Bathyamaryllis genus and belongs to it. The genus Bathyamaryllis was created by Pirlot (1933) and contains 6 species: B. haswelli (Stebbing, 1888), B. pulchellus (Bonnier, 1896), B. perezii Pirlot, 1933, B. ouvea Lowry & Stoddart, 1994, B. kapala Lowry & Stoddart, 2002, B. biscayensis n. sp.. Bathyamaryllis biscayensis n. sp. has the uropod 3 outer ramus 1 -articulate, and can be separated from Bathyamaryllis ouvea Lowry & Stoddart, 1994 and Bathyamaryllis kapala Lowry & Stoddart, 2002 which have the uropod 3 outer ramus 2 -articulate. Bathyamaryllis biscayensis n. sp. has the lateral cephalic lobe reduced, triangular-shaped with the anterior margin slightly curved. These characters permit the separation of this species from Bathyamaryllis haswelli (Stebbing, 1888), Bathyamaryllis pulchellus (Bonnier, 1896) and Bathyamaryllis perezii Pirlot, 1933, which have the lateral cephalic lobe quadrate-shaped and the anterior margin straight.Published as part of Kaim-Malka, R.

“'Earthquake relief. Mexico. 2051'”: escrituras geológicas en un relato especulativo de Malka Older
No full textEn agosto de 2021, la plataforma informativa The New Humanitarian publicó su primera obra de ficción, el relato corto titulado “Earthquake relief. Mexico. 2051” [Alivio de terremoto. México. 2051”], de la escritora, poeta, investigadora y activista humanitaria Malka Older. El presente artículo propone un análisis del rol de la ciencia ficción o ficción especulativa como forma de investigación que puede contribuir a extrapolar perspectivas y metodologías de las artes, las humanidades y la escritura creativa al terreno de la colaboración interdisciplinaria, los discursos sobre desastres y las políticas medioambientales. Las ideas de Cristina Rivera Garza sobre “escrituras geológicas” contribuyen al estudio de las estrategias escriturales empleadas por Malka Older para interrogar pasado, presente y futuro, y exponer sus contradicciones a través de la especulación. El fin último de este trabajo académico es contribuir a comprender el rol de las artes, las humanidades y la ficción especulativa en la construcción de narrativas sobre desastres donde factores culturales y afectivos coexistan con informaciones y perspectivas técnicas. Un nuevo tipo de narrativas sobre desastres, que involucre los saberes de las artes y las humanidades, puede no sólo alertar sobre problemas medioambientales, sino crear conexiones más horizontales entre comunidades vulnerables, investigadores, líderes y organismos internacionales, en favor de la mitigación y recuperación con perspectiva descolonizadora y de justicia medioambiental.

Replication Data for: Are Cultural and Economic Conservatism Positively Correlated? A Large-Scale Cross-National Test
No full textThe right-left dimension is ubiquitous in politics, but prior perspectives provide conflicting accounts of whether cultural and economic attitudes are typically aligned on this dimension within mass publics around the world. Using survey data from 99 nations, we find not only that right-left attitude organization is uncommon, but that it is more common for culturally and economically right wing-attitudes to correlate negatively with each other, an attitude structure reflecting a contrast between desires for cultural and economic protection vs. freedom. We examine where, among whom, and why protection-freedom attitude organization outweighs right-left attitude organization, and discuss implications for the psychological bases of ideology, quality of democratic representation, and the rise of extreme right politics in the West

Proportion of Severe Asthma Patients Eligible for Mepolizumab Therapy by Age and Age of Onset of Asthma
No full textBackground: Mepolizumab is an anti–IL-5 antibody approved for the treatment of severe eosinophilic asthma. However, the prevalence of patients with severe asthma eligible for mepolizumab remains unknown, especially among children. Objective: To determine, in a population of patients with severe asthma from a tertiary referral center, the proportion of patients with an eosinophilic phenotype who would be eligible for mepolizumab, when stratified for the age of onset of asthma, and the prevalence of phenotypic features that favor mepolizumab therapy. Methods: An extensive database of 245 adults and children referred for severe asthma was used. The prevalence of severe asthma was estimated by using the European Respiratory Society/American Thoracic Society criteria. Patients with an eosinophilic uncontrolled phenotype qualified for mepolizumab. Results: In our cohort, 216 (88%) had severe asthma. Based on blood eosinophils of either greater than or equal to 150 cells/μL or greater than or equal to 300 cells/μL, 61%/41% had an eosinophilic phenotype, while 49%/34% were eligible for mepolizumab therapy. A greater percentage of adults (60%/47% of adults with asthma onset in adulthood [AoA] and 48%/26% adults with childhood-onset asthma [<18 years, CoA]) were eligible compared with children (33%/24%), for eosinophil counts of ≥150 and ≥300 cells/μL, respectively; P < .05. Compared with adults, children had a similar number of exacerbations while having better lung function (P < .05). Among adults, those with AoA were older, were more likely to have nasal polyps (28% vs 5%; P < .05), and had higher blood eosinophil counts (272 vs 150 cells/μL; P < .05) compared with those with CoA, with no difference in lung function noted between the 2 groups. Subjects showing greater than or equal to 500 eosinophils/μL, a strong indicator for mepolizumab therapy, had more nasal polyps, higher inhaled steroid dose, lower lung function, and AoA predominance than did those with less than 500 eosinophils/μL (P < .05). Conclusions: A smaller percentage of children with severe asthma were eligible for mepolizumab compared with their adult peers. Severe AoA has distinct phenotypic features that favor treatment with mepolizumab, including greater eosinophilia and nasal polyposis, in contrast to CoA, which appears to have fewer features of type 2 mucosal inflammation
