The modeling of multiple animals that share behavioral features [PDF]
arXiv, 2021 In this work, we propose a model that can be used to infer the behavior of multiple animals. Our proposal is defined as a set of hidden Markov models that are based on the sticky hierarchical Dirichlet process, with a shared base-measure, and a STAP emission distribution.

Survive the economic downturn: Operating flexibility, productivity, and stock crash
Journal of Operations Management, EarlyView.Abstract Operating flexibility supports a firm's resilience strategy during challenging times by enabling them to promptly cut down operating costs associated with unproductive resources. We employ a real options model to formalize this insight. Our empirically grounding analytics motivate a firm‐level proxy for downscale operating flexibility (FLEX ...

Learning Health Systems, EarlyView.Abstract Introduction In the United States, only 8.2% of people treated for out‐of‐hospital cardiac arrest (OHCA) in 2023 survived with good neurological function. The interval from the onset of cardiac arrest to the start of CPR and defibrillation is strongly associated with survival and neurologic recovery.

Prior-Aware Synthetic Data to the Rescue: Animal Pose Estimation with Very Limited Real Data [PDF]
arXiv, 2022 Accurately annotated image datasets are essential components for studying animal behaviors from their poses. Compared to the number of species we know and may exist, the existing labeled pose datasets cover only a small portion of them, while building comprehensive large-scale datasets is prohibitively expensive.

Metabolic scaling is governed by Murray's network in animals and by hydraulic conductance and photosynthesis in plants [PDF]
arXiv, 2022 The prevailing theory for metabolic scaling is based on area-preserved, space-filling fractal vascular networks. However, it's known both theoretically and experimentally that animals' vascular systems obey Murray's cubic branching law. Area-preserved branching conflicts with energy minimization and hence the least-work principle.

Learning by doing, organizational forgetting, and the business cycle
Bulletin of Economic Research, Volume 75, Issue 1, Page 141-150, January 2023., 2023 Abstract This paper supplements a learning‐by‐doing real business cycle model with endogenous organizational forgetting. Empirical evidence shows that the accumulated experience decay rate is not constant over the business cycle, but that forgetting is a function of economic activity.

Factors limiting plant recruitment in a tropical Afromontane Forest
Biotropica, Volume 55, Issue 1, Page 221-231, January 2023., 2023 Which species are most likely to successfully recruit depends on a multitude of factors, but with processes operating at the seed‐to‐seedling transition being especially important. In this study, we explore how insufficient seed dispersal (dispersal limitation) and ecological filtering of seedlings (establishment limitation) influence species ...

Children &Society, Volume 37, Issue 1, Page 254-269, January 2023., 2023 Abstract Based on in‐depth interviews with 24 middle‐class Indian child participants, this is the first exploratory qualitative study, in India, to demonstrate the ways in which children as reflexive social actors re‐negotiated everyday schedules, drew on classed resources at their disposal and made sense of the impact of the pandemic on their ...

People and Nature, EarlyView.Abstract Reciprocity and relationality are themes which frequently emerge with respect to human–nature associations in Indigenous groups around the world. But many hunter‐gatherers have been shown to reject systems of reciprocity, instead favouring unconditional sharing both between each other and their environment through egalitarian social structures.

People and Nature, EarlyView.Abstract The recovery of marine ecosystems in areas heavily impacted by fishing and environmental exploitation depends, to some extent, on the sustainable management of resources and should be complemented by cultural traditions, practices and scientific knowledge.
