On the Betti Numbers of some Classes of Binomial Edge Ideals [PDF]
The Electronic Journal of Combinatorics, 2013 We study the Betti numbers of binomial edge ideal associated to some classes of graphs with large Castelnuovo-Mumford regularity. As an application we give several lower bounds of the Castelnuovo-Mumford regularity of arbitrary graphs depending on induced subgraphs.

Business Strategy and the Environment, EarlyView.ABSTRACT Firms' strategic decision‐making relies not only on their own information but also on that disclosed by supply chain partners. While research recognizes buyers' importance in green innovation, the impact of their information disclosure remains underdeveloped. Drawing on the extended resource‐based view, this study investigates the joint effect

Out of Sight, Out of Mind: Digitalization's Double Role in Driving Sustainable Transition
Business Strategy and the Environment, EarlyView.ABSTRACT This paper investigates the role of digitalization in overcoming organizational barriers to sustainability. Drawing on the attention‐based view (ABV) theory, the study examines how digitalization, as a contextual condition, shapes the allocation of managerial attention, influences the perception of sustainability barriers, and ultimately ...

Carbon Markets and Green Innovation: Path‐Dependent Firm Responses to Emissions Trading
Business Strategy and the Environment, EarlyView.ABSTRACT This paper identifies a dynamic boundary condition of the Porter hypothesis by examining how firms' pre‐existing innovation trajectories shape regulatory‐induced green innovation within the context of a market‐based carbon policy. Building on path dependency theory, we argue that firms' responses to environmental regulation are contingent on ...

Cohen-Macaulay generalized binomial edge ideals
, 2023 Let $G$ be a simple graph on $n$ vertices and let $J_{G,m}$ be the generalized binomial edge ideal associated to $G$ in the polynomial ring $K[x_{ij}, 1\le i \le m, 1\le j \le n]$. We classify the Cohen-Macaulay generalized binomial edge ideals. Moreover

Standardization Without Convergence: Organizational Perspectives on Social Impact Measurement
Business Strategy and the Environment, EarlyView.ABSTRACT This study examines how organizations engaged in social impact activities perceive the desirability of standardizing social impact measurement. Drawing on survey data from 785 organizations, the analysis adopts an organization‐centered perspective and combines descriptive statistics, cluster analysis, and regression models.

Sparse maximum likelihood estimation of regression models
Canadian Journal of Statistics, EarlyView.Abstract For regression model selection and estimation, we study a small set of candidate models of maximum likelihood from which all information criteria such as the Akaike information criterion (AIC) and the Bayesian information criterion (BIC) choose their models.

A Study of the Local Cohomology of Binomial Edge Ideals [PDF]
In this thesis, we apply local cohomology to the study of binomial edge ideals in order to establish three main results: 1. A combinatorial characterisation of graphs whose binomial edge ideals are of König type. 2.

Estuarine benthic diversity declines with temperature across a tropical–temperate gradient
Ecography, EarlyView.Estuarine benthic sediments are important habitats that support ecosystem health and productivity, but the drivers of large‐scale patterns in benthic diversity are not well documented. Using 18S amplicon sequencing of 425 sediment DNA samples from estuaries spanning 20° of latitude along Australia's east coast, we assessed tropical–temperate patterns ...
