Bounds on the Signed Roman k-Domination Number of a Digraph [PDF]

, 2019
Let k be a positive integer. A signed Roman k-dominating function (SRkDF) on a digraph D is a function f : V (D) → {−1, 1, 2} satisfying the conditions that (i) Σx∈N−[v]f(x) ≥ k for each v ∈ V (D), where N−[v] is the closed in-neighborhood of v, and (ii)

Developmental differences in cortical bone structure in chimpanzee and human femora reflect early locomotor independence in humans

The Anatomical Record, EarlyView.
Abstract The cortical bone structure of long bone diaphyses changes throughout growth via skeletal modeling and has important implications for bone strength and structural integrity. Ontogenetic trends in diaphyseal structure have been identified in both chimpanzees and humans but it is not yet clear how these trends compare given notable differences ...

Optimizing Strategies for Non‐Invasive Prospection of Settlements in the Intertidal Zone: A Case Study From the Centre of the Drowned Medieval Village of Tolsende (Scheldt Estuary, the Netherlands)

Archaeological Prospection, EarlyView.
ABSTRACT Medieval and early modern drowned villages in the intertidal zone of the Scheldt estuary (the Netherlands) constitute intriguing yet largely understudied components of north‐western Europe's underwater cultural heritage. Despite their high archaeological potential as time capsules of past settlement landscapes, research has remained limited ...

Chilean science teachers' conceptualisations of disability when teaching students with autism

British Educational Research Journal, EarlyView.
Abstract This study examines how Chilean secondary science teachers conceptualise disability when teaching students with autism in integrated classroom settings. Grounded in critical disability studies, the research employs a qualitative story‐completion method, using a fictional classroom scenario to prompt teachers to construct narratives that reveal

Weak signed Roman k-domination in digraphs [PDF]

Let $ k ≥ 1 $ be an integer, and let $ D $ be a finite and simple digraph with vertex set $ V (D) $. A weak signed Roman k-dominating function (WSRkDF) on a digraph $ D $ is a function $ f : V (D) → {−1, 1, 2} $ satisfying the condition that $ \Sigma_{x ...

Reframing Colonial Korea's Forests Through Protection Forests: The Forests of Joseon (1938)

Berichte zur Wissenschaftsgeschichte, EarlyView.
This study examines The Forests of Joseon (1938), a forestry survey compiled by Tokumitsu Nobuyuki under Japanese colonial rule, as a key site of epistemic negotiation between imperial forestry science and Korean indigenous knowledge. Focusing on bíbo forests—geomantic forests believed to regulate energy flow between mountains and villages—the paper ...

Navigating the Double Edge of Product‐Service Systems: User Behavior, Adoption, and Rebound Effects

Business Strategy and the Environment, EarlyView.
ABSTRACT Product‐service systems (PSS) have been considered a promising approach to operationalizing the circular economy. Although many studies have outlined the potential sustainability gains of PSS solutions, it is still unclear what factors drive PSS adoption and how behavioral changes result in rebound effects, undermining their potential ...

Corporate Dynamic Eco‐Innovation Capability and Carbon Emission Reduction: Evidence From African Listed Firms With the Role of Institutional Pressures

Business Strategy and the Environment, EarlyView.
ABSTRACT Despite the global emphasis on simultaneous achievement of higher growth and lower pollution (green growth), the dynamic link between eco‐innovation and CO2 emissions remains inadequately understood globally and specifically in Africa, with a complex and diverse institutional and regulatory landscape.
