Guided Toward Equity: Communities of Practice and Organizational Change in Community Colleges

New Directions for Community Colleges, EarlyView.
ABSTRACT Although community colleges advance equity by providing opportunities for marginalized students to pursue higher education, barriers to earning credentials remain, particularly for students of color. Higher education stakeholders are investing in “equity work” as organizations take responsibility for ensuring equitable outcomes.

Total roman domination in digraphs

, 2021
Let D be a nite and simple digraph with vertex set V (D). A Roman dominating function (RDF) on a digraph D is a function f : V (D) → {0; 1; 2} satisfying the condition that every vertex v with f(v) = 0 has an in-neighbor u with f(u) = 2. The weight of an

Development of a Mechanically Regenerating Desublimator for Freeze‐Drying Systems in the Food Industry

Chemie Ingenieur Technik, EarlyView.
Thermal defrosting limits desublimator efficiency in freeze‐drying. This review and case study compares thermal versus mechanical regeneration, links frost properties and external heat transfer to energy demand, and summarizes pilot‐scale scraping results enabling single‐unit, continuous lyophilization.

Complexity and exact values for []-Roman and strong Roman domination for specific graph families

Motivated by the original idea of defending the Roman Empire, all these domination concepts can be interpreted as vertex-labeling schemes that model the allocation of resources to protect a graph against attacks.

Roman domination in graphs

, 2000
A Roman dominating function on a graph G =(V,E) is a function f: V →{0, 1, 2} satisfying the condition that every vertex u for which f(u) =0 is adjacent to at least one vertex v for which f(v)=2.Theweight of a Roman dominating function is the value f(V) =

On a generalization of Roman domination with more legions

, 2022
In this note, we generalize the concepts of (perfect) Roman and Italian dominations to (perfect) strong Roman and Roman k-domination for arbitrary positive integer k. These generalizations cover some of previous ones.

Vine copula knockoffs for variable selection in gene expression studies

Canadian Journal of Statistics, EarlyView.
Abstract Identifying clinical and genetic markers is essential for stratifying cancer patients by survival outcomes and guiding personalized treatment strategies. However, gene expression studies often involve high‐dimensional predictors with mixed data types and complex dependence, which complicates reliable variable selection.

Digitalization in Sustainability Reporting and Text Attributes of Non‐Financial Disclosure: Evidence From Italian Listed Companies

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Recent regulatory initiatives, including the EU Corporate Sustainability Reporting Directive (CSRD), are reinforcing the demand for more structured, transparent, and accessible sustainability reporting. However, empirical evidence on how digital tools influence the narrative dimension of these disclosures remains limited.
