Six Ca‐Mg‐Fe Carbonate Reference Materials for In Situ Measurement of Oxygen and Carbon Isotope Ratios

open access: yesGeostandards and Geoanalytical Research, EarlyView.
Key Points Six new Ca‐Mg‐Fe carbonate reference materials are available to the global geochemical community for calibrating oxygen and carbon isotope ratios by SIMS. Significant compositional matrix effects were observed in the dolomite‐ankerite and magnesite‐siderite series during SIMS analysis. Compositional matrix effects correlate with Fe variation.

New Magnetite Reference Material for SIMS δ18O Measurements and a Study of Precision and Accuracy Due to Crystal Orientation Effects

open access: yesGeostandards and Geoanalytical Research, EarlyView.
Key Points A new magnetite reference material (PF21mt) is available for δ18O measurements by SIMS. Reproducibility of measurement results in two laboratories suggest orientation bias of ±2‰ (2s) at 20 keV. Repeatability improves to ±1‰ (2s) when using a 13 keV protocol, suggesting reduced orientation bias. In situ isotope ratio measurements provide the

Fiscal Opacity and Lack of Consensus in Expectations for External Sector Variables

open access: yesInternational Finance, EarlyView.
ABSTRACT Fiscal transparency is essential for the expectations formation process, as governmental fiscal opacity often leads to forecast errors due to insufficient information. This study examines the relationship between fiscal unpredictability, particularly related to the primary budget, and the lack of consensus in expectations for external sector ...

Partisanship, Ethnicity and Tax Policy Perceptions: Investigating Public Responses to Ghana's E‐Levy

open access: yesInternational Social Science Journal, EarlyView.
ABSTRACT This study examines the determinants of public opinion on Ghana's electronic transaction levy (E‐Levy), focusing on party politics and ethnic identity roles. The E‐Levy, introduced in 2022, imposed a 1.75% tax on electronic transactions, sparking a nationwide debate. A review of E‐Levy implementation across Africa revealed mixed outcomes, with
