In Situ Impact of Waste Polyethylene (PE) Films on Soil Quality and Plant Growth in Agricultural Soil

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Plastic films have accumulated in soil ecosystems over decades of agricultural activities. These films potentially disrupt the soil structure, hinder nutrient cycling, and deteriorate soil quality. However, there is still a substantial knowledge gap in understanding how real‐world waste polyethylene films (WPEFs), with varied shapes and sizes,

Improper colourings of graphs

open access: yes, 2016
We consider a generalisation of proper vertex colouring of graphs, referred to as improper colouring, in which each vertex can only be adjacent to a bounded number t of vertices with the same colour, and we study this type of graph colouring problem in several different settings. The thesis is divided into six chapters.

Does polymixis complicate prediction of high‐frequency dissolved oxygen in lakes and reservoirs?

open access: yesLimnology and Oceanography, EarlyView.
Abstract As lake and reservoir ecosystems transition across major environmental regimes (e.g., mixing regime) resulting from anthropogenic change, setting predictive expectations is imperative. We tested the hypothesis that (dissolved) oxygen is more predictable in monomictic reservoirs that thermally stratify throughout the summer (warm) season ...

Development of Environment‐Time‐Dependent Material Selection Maps for Alloy 718 Under Crevice Conditions in Aerated Seawater

open access: yesMaterials and Corrosion, EarlyView.
This study introduces material selection maps—that is, charts indicating crevice corrosion resistance as a function of temperature and electrochemical potential—illustrating their applicability using nickel‐based alloy 718 as a case study. Crevice corrosion susceptibility maps developed in this study are a new approach that shows how environmental ...

Validation of an Existing Racial and Ethnic Microaggressions Scale Within the City of Tshwane Metropolitan Municipality in South Africa

open access: yesPublic Administration and Development, EarlyView.
ABSTRACT The local government workplace in post‐apartheid South Africa represents an important environment to examine employee perceptions on the occurrence of microaggressions. However, since the advent of democracy in 1994, the country has faced numerous challenges in its quest for the implementation of rights pertaining to unity, diversity ...

Intermarriage amid immigration status uncertainty: Evidence from DACA

open access: yesJournal of Policy Analysis and Management, EarlyView.
Abstract In 2012, the Obama administration issued the Deferred Action for Childhood Arrivals (DACA) program by executive order. Since then, more than 800,000 undocumented immigrants who arrived as children have benefited from renewable 2‐year reprieves from deportation and work permits.

Food Safety Practices and Foodborne Illness in Italian Pediatric Oncology and Hematology Centers: A Survey on Behalf of the Infectious Disease Working Group of AIEOP

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Food safety practices are widely recommended for pediatric patients with cancer or undergoing hematopoietic stem cell transplantation (HCT) to mitigate foodborne infectious risks. However, specific measures, such as the neutropenic diet (ND) or low‐microbial diet, lack robust evidence and are inconsistently implemented across ...

Harmonising digitised herbarium data to enhance biodiversity knowledge: Major steps towards an updated checklist for the flora of Greenland

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Herbaria worldwide hold centuries of plant data that are key to understanding and protecting biodiversity; however, even with increased digital access, differences in plant naming systems make it difficult to compare records. We developed a semi‐automated workflow that standardises species names and organises herbaria records from multiple institutions
