A Right‐Wing Populist Turn in the Conservative Party of Canada? Continuities and Ruptures Under the Leadership of Pierre Poilievre (2022–2025)

open access: yesCanadian Review of Sociology/Revue canadienne de sociologie, Volume 63, Issue 2, May 2026.
ABSTRACT Since his election as leader of the Conservative Party of Canada (CPC) in 2022, Pierre Poilievre has been associated with populism in media and political discourse, with implicit and explicit comparisons to Donald Trump. This article investigates the validity of such assessments by applying “complex” theories of populism, which conceptualize ...

Reduced sediment accumulation rate enhances early marine diagenesis of periplatform sediments

open access: yesThe Depositional Record, Volume 12, Issue 2, April 2026.
The influence of reduced sediment accumulation rate on early marine burial diagenesis was investigated in sediments collected by ODP Leg 133. Results show that low sediment accumulation rates can produce substantial and asynchronous shifts in stable carbon isotope ratios across a slope transect without the development of sedimentological indicators of ...

Speculative Bubbles and Control Theory—An Endogenous Approach

open access: yesSystem Dynamics Review, Volume 42, Issue 2, April/June 2026.
ABSTRACT Speculative bubble formation has been a long observed feature of markets, and continues to be a major focus of behavioral finance, economics, marketing, and operations management research. While these bubbles arise from specific physical or informational features of specific markets, their formation is also driven by the interplay between ...

No Groundwater, No Fish: The Critical Role of Groundwater in Supporting Non‐Glacial, Salmon‐Bearing Rivers in South‐Central Alaska

open access: yesJAWRA Journal of the American Water Resources Association, Volume 62, Issue 2, April 2026.
ABSTRACT Groundwater discharge plays an important role in the hydrologic and ecologic functioning of rivers including sustaining streamflow and related habitat year‐round. Simultaneously, groundwater supports the increasing demands of people as the global population continues to grow.

Legitimising the Food Regime in Post‐Socialist Croatia: A Critical Discourse Analysis of Croatia's Agricultural Strategies, 1991 to 2013

open access: yesJournal of Agrarian Change, Volume 26, Issue 2, April 2026.
ABSTRACT What role has the state played in the establishment of the current food regime in a post‐socialist setting? Focusing on Croatia, I undertake a critical discourse analysis of the national agricultural strategies enacted during the neoliberal transition between 1991 and 2013.

Depositional Facies, Sequence Stratigraphy, and Diagenesis of Lower Cretaceous Carbonate Reservoir, Southern Iraq: Implications for Petroleum Exploration

open access: yesJournal of Petroleum Geology, Volume 49, Issue 2, Page 312-345, April 2026.
ABSTRACT The Lower Cretaceous Yamama Formation of southern Iraq represents a key carbonate reservoir within Iraq and the Middle East, yet its complex depositional facies architecture and diagenetic alterations present challenges for predicting reservoir quality.

Long‐Term Storage of Meteoric Water in the Variscan Basement: Stable Isotope Constraints (δD–δ18O)

open access: yesTerra Nova, Volume 38, Issue 2, Page 116-123, April 2026.
ABSTRACT F‐Ba‐Pb‐Zn (±Ag) deposits near the unconformity between the Armorican and Aquitaine basins formed by mixing surface waters and brines with fluid ascending from the basement. To better constrain the source of this fluid and the conditions of mixing, we analyzed the hydrogen (δDwater) and oxygen (δ18Owater) isotopic composition of water trapped ...

Thousand‐Kilometer‐Scale Wavelike Undulations in Ionospheric Plasma Bubble Lifetime and Development Over Wide Longitudes

open access: yesGeophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract The irregularities of ionospheric plasma bubbles (EPBs) sequentially generated over wide longitudes are expected to share similar lifetime under normal conditions. In this study, we report a special case where the EPB irregularity lifetime over wide longitudes showed a quasi‐wavelike undulation pattern with wavelength of ∼3,000 km, that is ...
