Novel Bernstein‐Kantorovich Type Operators

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In this paper, we introduce a novel class of Bernstein‐Kantorovich operators, denoted as Kβn,θ$$ {K}_{\beta}^{n,\theta } $$, parameterized by 0<β<1$$ 0<\beta <1 $$ and θ>0$$ \theta >0 $$. We first derive a recurrence formula that facilitates the computation of moments and central moments and provide explicit expressions for Kβn,θ(tm;x)$$ {K}_{\

Business‐Like Narrative and Public Engagement: Evidence From TED Talks on Nonprofit Issues

open access: yesNonprofit Management and Leadership, EarlyView.
ABSTRACT While the trend of nonprofits adopting business‐like practices has been widely discussed, limited attention has been paid to how the broader public responds to this shift. One way to capture public reactions is by examining engagement with business‐like narratives in media.

Exploring the Role of Special Events in Relationship Fundraising

open access: yesNonprofit Management and Leadership, EarlyView.
ABSTRACT The relationship fundraising paradigm conceptualizes charitable giving as an outcome of ongoing interpersonal engagement between donors and organizations, often depicted in practice as a cyclical process with multiple phases. This study examines how special events—a widely used but understudied relationship fundraising tool—factor into this ...

Coverage‐based rarefaction fails to quantify relative species richness

open access: yesOikos, EarlyView.
Coverage‐based rarefaction (CBR) is a high‐profile tool for assessing biodiversity that provides relative species richness estimates by leveraging the Good‐Turing index u to interpolate. In contrast to alternatives such as the Shannon and Simpson indices, CBR's main appeal is providing values in units of species. CBR is tested against a series of other

A framework for investigating fish population density responses to habitat fragmentation

open access: yesOikos, EarlyView.
Globally, fish populations that rely on rivers are being fragmented by in‐stream barriers, but it is unclear how pervasive any negative population responses to fragmentation are. We developed a modeling framework for estimating density responses of fishes upstream and downstream of in‐stream barriers and applied it to learn how low‐head dams have ...
