Generalized Stirling Numbers and Generalized Stirling Functions

, 2011
Here presented is a unified approach to Stirling numbers and their generalizations as well as generalized Stirling functions by using generalized factorial functions, $k$-Gamma functions, and generalized divided difference. Previous well-known extensions of Stirling numbers due to Riordan, Carlitz, Howard, Charalambides-Koutras, Gould-Hopper, Hsu-Shiue,

Investigating conservation performance payments alongside human–wildlife conflicts: The Swedish lynx and wolverine protection policies

People and Nature, EarlyView.
Abstract Conservation performance payments are becoming an increasingly popular instrument to tackle human–wildlife conflicts. In Sweden, Sámi communities practicing reindeer husbandry receive performance payments as compensation for reindeer losses caused by lynxes and wolverines.

Tree planting, natural colonisation, hybrid approaches: Land manager decisions explored

People and Nature, EarlyView.
Abstract There is a global drive to protect biodiversity and help combat climate change. In the UK, this is expressed in a number of policy initiatives and tools that include increasing tree cover as an important nature‐based solution to achieving national policy targets.

The impact of COVID‐19 on public perceptions of wild meat in Central Africa

People and Nature, EarlyView.
Abstract Wild meat is a significant source of food and income generation in Central Africa. However, there is little knowledge of how the assumed link between COVID‐19 and wild meat consumption has been discussed by the media and received by the public. In this study, we conducted media content analysis of 264 articles published in 2019–2020 related to

Coping with climate emotions: A qualitative study using interviews and letters in remote, rural and small communities across Canada

People and Nature, EarlyView.
Abstract The consequences of climate change are becoming more severe and widespread, highlighting the growing need to understand and address the emotional dimensions of the climate crisis. Although research on climate emotions has grown substantially over the past decade, empirical work on how people are coping with climate emotions is very limited ...

Delousing performance of ballan wrasse (Labrus bergylta) and lumpfish (Cyclopterus lumpus): seasonal consistency and the challenge of cryptic lice for lumpfish

Pest Management Science, EarlyView.
Ballan wrasse and lumpfish effectively reduce sea lice on salmon year round, although lumpfish struggle with cryptic lice, highlighting new considerations for lice management. Abstract BACKGROUND Cleaner fish play a crucial role in controlling caligid sea lice in Atlantic salmon aquaculture across the North Atlantic.

Explicit formulae for Bernoulli numbers

AIMS Mathematics
By examining the connection coefficients, we systematically review and extend (with an extra integer parameter) several double sum expressions for the Bernoulli numbers. New summation formulae are also established explicitly.
