Wind‐driven seed dispersal differentially promotes seed trapping and retention across alpine plants

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Seed dispersal can mediate species interactions between plants across life stages. Plants can physically stop seed movement (seed trapping) and prevent further dispersal following entrapment (seed retention). We therefore hypothesized seed trapping and retention rates depend on the physical attributes of interacting seeds and plants ...

Repeated sums and binomial coefficients

open access: yesOpen Journal of Discrete Applied Mathematics, 2021
Binomial coefficients have been used for centuries in a variety of fields and have accumulated numerous definitions. In this paper, we introduce a new way of defining binomial coefficients as repeated sums of ones. A multitude of binomial coefficient identities will be shown in order to prove this definition.

Giving and receiving help in three contexts as predictors of alcohol outcomes in a longitudinal study of sober living house residents

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract Although peer support is central to the social model approach emphasized in sober living houses (SLHs), no longitudinal studies have examined helping among SLH residents. This longitudinal study examined benefits of helping in three contexts among SLH residents. Data were from 205 participants entering 28 SLHs across 2021–2023. Interviews were

Multiple Sums of Circular Binomial Products

open access: yesMathematics
Five classes of multiple sums about circular products of binomial coefficients are investigated. Their generating functions are explicitly expressed as rational functions, with coefficients being Fibonacci and Lucas numbers.

Number of odd binomial coefficients [PDF]

open access: yesProceedings of the American Mathematical Society, 1977
Let F ( n ) F(n) denote the number of odd numbers in the first n rows of Pascal’s triangle, and θ = ( log ⁡ 3 ) / log ⁡ 2 ) \theta = (\log 3)/\log 2) . Then α = lim

Associations between inclusive community coalition leadership and use of evidence‐based practices

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract Community coalitions have the potential to elicit diverse participants' perspectives on complex issues and generate shared commitment to adaptive strategies. Ideally, these approaches have been found effective elsewhere. Despite evidence that leadership plays a generally important role in coalitions, there have been limited prior findings ...

Triple Symmetric Sums of Circular Binomial Products

open access: yesMathematics
By employing the generating function approach, 16 triple sums for circular binomial products of binomial coefficients are examined. Recurrence relations and generating functions are explicitly determined.
