Animal empathy reconsidered: a multidimensional profile account

open access: yesBiological Reviews, EarlyView.
ABSTRACT Empathy is the glue that holds societies together and yet several fundamental questions about empathy persist. What is empathy (the definitional question)? Is it uniquely human and, if not, which nonhuman animals possess empathy (the distribution question)? Which type or quality of empathy is realized in different species (the quality question)

A numerical method for the expected penalty–reward function in a Markov-modulated jump–diffusion process. [PDF]

open access: yes
A generalization of the Cramér–Lundberg risk model perturbed by a diffusion is proposed. Aggregate claims of an insurer follow a compound Poisson process and premiums are collected at a constant rate with additional random fluctuation.

Evidence for adaptive explanations of semelparity in animals

open access: yesBiological Reviews, EarlyView.
ABSTRACT Semelparity, the reproductive strategy of reproducing once, is widespread but uncommon in animals. Classes of models to explain the evolution of semelparity are based either on age structure and mortality schedules – demographic models in which high post‐reproductive mortality risk favours high reproductive effort and semelparity results from ...

Hot and cold deserts as eco‐evolutionary arenas for understanding plant resistance to multiple abiotic stressors

open access: yesBiological Reviews, EarlyView.
ABSTRACT During their long evolutionary history, land plants have evolved a range of adaptations to different abiotic stressors. These help explain present‐day diversity and distribution patterns, as well as the potential resilience of natural and agricultural systems to a changing climate. Most previous research has focused on adaptation to individual

Ruin probabilities in a finite-horizon risk model with investment and reinsurance [PDF]

open access: yes
A finite horizon insurance model is studied where the risk/reserve process can be controlled by reinsurance and investment in the financial market. Obtaining explicit optimal solutions for the minimizing ruin probability problem is a difficult task ...

Addressing the Energy Trilemma: The Role of Entrepreneurship, Regulation, and Climate Finance

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Balancing energy security, energy equity, and environmental sustainability has become increasingly challenging as economies pursue low‐carbon growth amid climate risk and persistent disparities in access to modern energy. Although entrepreneurship is widely recognized as a driver of innovation, its role in addressing the energy trilemma ...

Inequalities for the ruin probability in a controlled discrete-time risk process [PDF]

open access: yes
Ruin probabilities in a controlled discrete-time risk process with a Markov chain interest are studied. To reduce the risk there is a possibility to reinsure a part or the whole reserve.

Beyond the Reports: Cultural Pressures, Unheard Voices and the Climate Accountability Gap in Oil and Gas Sector Governance

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Environmental governance in Nigeria's oil and gas sector remains central to global climate justice debates, yet persistent accountability failures continue to undermine meaningful environmental and social outcomes. Despite extensive regulatory frameworks, accountability in resource‐dependent contexts is frequently reduced to formal reporting ...
