Ostracods from the late Mississippian–early Pennsylvanian (late Serpukhovian–Bashkirian) from the Calingasta–Uspallata Basin, Precordillera Argentina, are studied for the first time. The analyzed successions (Hoyada Verde, El Paso, Leoncito, and Yalguaraz formations) document the most widespread glacial event in southwestern Gondwana during the Late Paleozoic Ice Age. One new species, Aechmina cuyanensis new species, is defined, and seven species are described, two of which are new records for South America. The distribution of Carboniferous ostracods in the Argentine basins (Calingasta–Uspallata, Río Blanco, and Tepuel–Genoa) is discussed, highlighting the interesting record of this fauna in levels between or below diamictites and its absence in the mudstone interval with no evidence of glaciation. The association is characterized by ornamented palaeocopids, one binodicopid, and some metacopid species corresponding to the Assemblage III of the Eifelian Mega-Assemblage, indicating a slightly hypoxic and very calm environment between the fair-weather wave base and the storm wave base.

The present study examines the influence of non-economic factors on women’s labour market participation in low-income neighbourhoods of urban areas in India. For this purpose, we conducted a survey in two slum areas of Kolkata city in West Bengal – one, located in a residential neighbourhood, and another, situated in the dock area of the city and surrounded by factories. Our survey of 384 ever-married working-age women makes three noteworthy observations. First, the location of slums crucially affects the type of paid work that is available and accessible to women. Secondly, although women’s entry into the labour market maybe crisis-driven, the women workers develop an intrinsic valuation of paid work as their right, and as a means of livelihood in the process. Finally, social and community norms explain both the non-participation and the temporary withdrawal of women from the labour force. Thus, the inability and/or the unwillingness of slum women to participate in the labour market primarily stem from the strict adherence to patriarchal norms in general, and community norms in particular, either imposed on them directly by their spouses or indirectly by the community they reside in. Therefore, our analysis highlights the need for tailor-made policies that meet locality-specific needs.

With increasingly available computer-based or online assessments, researchers have shown keen interest in analyzing log data to improve our understanding of test takers’ problem-solving processes. In this article, we propose a multi-state survival model (MSM) to action sequence data from log files, focusing on modeling test takers’ reaction times between actions, in order to investigate which factors and how they influence test takers’ transition speed between actions. We specifically identify the key actions that differentiate correct and incorrect answers, compare transition probabilities between these groups, and analyze their distinct problem-solving patterns. Through simulation studies and sensitivity analyses, we evaluate the robustness of our proposed model. We demonstrate the proposed approach using problem-solving items from the Programme for the International Assessment of Adult Competencies (PIAAC).
