Three children who displayed destructive behavior maintained by negative reinforcement received functional communication training (FCT). During FCT, the children were required to complete a demand and then to mand (touch a card attached to a microswitch, sign, or vocalize) to receive brief play breaks. Prior to and 1 to 3 times following the initiation of FCT, extinction probes were conducted to evaluate the resurgence of destructive behavior when the microswitch without the mand card was present or the microswitch and the mand card were absent to determine if different patterns of resurgence occurred when the microswitch was present or absent and, for 2 of the children, if changes in resurgence occurred at different points in treatment. Results showed that FCT led to relatively rapid reductions in destructive behavior. During all extinction sessions, resurgence of destructive behavior occurred with only minimal differences across the switch/no card and no-switch conditions.

Background: Establishing accurate, reliable, and convenient methods for enamel segmentation and analysis is crucial for effectively planning endodontic, orthodontic, and restorative treatments, as well as exploring the evolutionary patterns of mammals. However, no mature, non-destructive method currently exists in clinical dentistry to quickly, accurately, and comprehensively assess the integrity and thickness of enamel chair-side. This study aims to develop a deep learning work, 2.

The mechanical properties of jointed rock bodies are important in guiding engineering design and construction. Using the particle flow software PFC2D, we conducted direct shear test simulations on joints with various inclinations and five different roughness levels to examine the models' crack extension penetration paths, damage modes, and strength characteristics. The findings indicate that the direction of the joint influences the pattern of the rock crack and its penetration route.

The phenomena of father's absence and the disruption of a family unit due to social justice issues like incarceration and mental health/substance misuse challenges are widely documented, and their effects on the whole family are well established in the literature. This paper specifically examines how systemic inequities like racism contribute to destructive entitlements that can occur transgenerationally within families affected by father's absence. The consideration of racial trauma is crucial, as father's absence and family disruption are not limited to any one racial or ethnic group, but the effects are often exacerbated for families of color due to the intersecting impacts of systemic racism.

The Spodoptera genus is defined as the pest-rich genus because it contains some of the most destructive lepidopteran crop pests, characterized by a wide host range. During feeding, the caterpillars release small amounts of oral secretion (OS) onto the wounded leaves. This secretion contains herbivore-induced molecular patterns (HAMPs) that activate the plant defense response, as well as effectors that may inhibit or diminish the plant's anti-herbivory response.
