Subtle relict channels associated with large dolines in an area formerly beneath the Laurentide Ice Sheet, northern Ohio, USA

Boreas, EarlyView.
Low‐relief dry channels appear out of place across a glaciated karst landscape in northern Ohio. Channels are only a few metres deep cut into limestone and draped with a veneer of till. Several hypotheses are proposed for explaining the channels. Low‐relief dry channels are observed across the Bellevue‐Castalia Karst Plain of north‐central Ohio, USA ...

Multiple solutions to fractional equations without the Ambrosetti-Rabinowitz condition

Electronic Journal of Differential Equations, 2017
In this article we study a class of fractional Laplace equations which do not satisfy the Ambrosetti-Rabinowitz condition (AR-condition). We establish the existence of three nontrivial solutions and of multiple sign changing solutions by using Morse ...

Morse theory for group presentations

Transactions of the American Mathematical Society
We introduce a novel combinatorial method to study Q ∗ ∗ Q^{**} -transformations of group presentations or, equivalently, 3-deformations of CW-complexes of dimension 2. Our procedure is based on a refinement of discrete Morse theory that gives a Whitehead simple homotopy equivalence from a ...

Scoping review: potential harm from school‐based group mental health interventions

Child and Adolescent Mental Health, EarlyView.
Background A growing body of evidence demonstrates that school‐based mental health interventions may be potentially harmful. We define potential harm as any negative outcome or adverse event that could plausibly be linked to an intervention. In this scoping review, we examine three areas: the types of potential harms and adverse events reported in ...

From Thought to Action: The Decision‐Making Process of Foster Parents

Child &Family Social Work, EarlyView.
ABSTRACT Although foster care represents an essential practice for helping children and families in difficult situations, nowadays, in Italy, the number of people open to engaging in this kind of care is limited compared to the real need, and agencies have difficulties recruiting new foster parents. The present qualitative study is aimed at identifying

Nontrivial solutions for nonlinear elliptic problems via Morse theory

Electronic Journal of Differential Equations, 2006
We prove the existence of nontrivial solutions for perturbations of p-Laplacian. Our approach combine minimax arguments and Morse Theory, under the conditions on the behaviors of the perturbed function $f(x,t)$ or its primitive $F(x,t)$ near infinity and

The Responsibiligated Status: Exploring the Experiences of Hearing Children With Deaf Parents

Child &Family Social Work, EarlyView.
ABSTRACT An individual with a disability influences every member of a family. While research on families with children with disabilities is extensive, studies focusing on families with parents with disabilities remain limited. A common situation in the deaf community is a family with deaf parents and hearing children.

Existence of solutions to a superlinear p-Laplacian equation

Electronic Journal of Differential Equations, 2001
Using Morse theory, we establish the existence of solutions to the equation $-Delta_p u = f(x,u)$ with Dirichlet boundary conditions. We assume that $int_0^s f(x,t),dt$ lies between the first two eigenvalues of the p-Laplacian.

Terrain descriptors for landscape synthesis, analysis and simulation

Computer Graphics Forum, EarlyView.
Abstract Synthetic landscape generation is an active research area within Computer Graphics. Algorithms for terrain synthesis and ecosystem simulations often rely on simple descriptors such as slope, light accessibility, and drainage area. Typically, the results are assessed from a perceptual standpoint, focusing primarily on visual plausibility. Other
