Chromatic numbers with open and nonzero local modular constraints Open
In this paper, we explore chromatic numbers subject to various local modular constraints. For fixed $n$, we consider proper integer colorings of a graph $G$ for which the closed and open neighborhood sums have nonzero remainders modulo $n$…

Private education and inequality in the knowledge economy Open
This article explores the consequences of public and private spending on education at all levels, looking at skills and income inequality. We use data for 22 affluent democracies from 1960 or 1995 (depending on data availability) to 2017. …

Financialization, labor market institutions and inequality Open
The last three decades have witnessed rising inequality and deepening financialization in post-industrial democracies. A rapidly growing literature has linked these two phenomena. We go beyond existing scholarship by specifying which aspec…

Goodbye to Meltzer-Richard: Testing major theories of redistribution Open
We re-analyse four major explanations of redistribution including the Meltzer-Richard model, power resources theory, Iversen-Soskice’s political institutions explanation, and Lupu and Ponstusson’s skewness theory. For each of these, we rec…

Chromatic numbers with closed local modular constraints Open
Generalizing the notion of odd-sum colorings, a $\mathbb{Z}$-labeling of a graph $G$ is called a closed coloring with remainder $k\mod n$ if the closed neighborhood label sum of each vertex is congruent to $k\mod n$. If such colorings exis…

Assessing trends and density of bird species in bottomland hardwood forests and riparian forests using simulation and sample size optimization for surveys Open
The decline of neotropical migratory birds in North America is closely tied to habitat loss, including the degradation of bottomland hardwood and riparian forests, which provide essential habitats for numerous species. To address this, the…

Ontological Indeterminacy and Intersubjectivity in Film Adaptations of Post-War English Children’s Books Open
When a novel is adapted as a film, the representation of the relationship between subject and society changes because of spatio-temporal modifications in narrative mode, period and location. Ideologies of childhood and hence children’s lit…
