Travelling the Two‐Way Street: Disrupting Colonial History

New Directions for Teaching and Learning, EarlyView.
ABSTRACT Using examples from the historical narratives about Kainai (Blackfoot Confederacy) painter Gerald Tailfeathers, this chapter challenges colonial narratives in Canadian history and historiography. Inspired by the author's participation in a Disrupting interview, the chapter explores both the author's personal history with colonial histories and

Microanalytical study of some cosmic dust discovered in sea-floor sediments in China [PDF]

The study of cosmic dust can provide useful data in the investigation of the origin of the Earth and the evolution of celestial bodies. Three types of cosmic dust (ferriginous, siliceous, and glassy) were discovered in the seafloor sediments near China ...

EU Space Law and Earth's Boundaries: Integrating Environmental Impact Assessment and Corporate Due Diligence

Global Policy, EarlyView.
ABSTRACT The European Union's proposed Space Law aims to establish a unified approach for sustainable space activities across the EU. While the EU's satellite constellations contribute to sustainability efforts, they can also have negative environmental impacts.

Palaeoenvironmental changes recorded at the Velika Vrbica loess‐palaeosol sequence, Wallachian Basin, during MIS 3–MIS 1

Boreas, EarlyView.
This study presents a detailed investigation of the Velika Vrbica loess‐palaeosol sequence, situated in the Wallachian Basin of northeastern Serbia, with the aim to reconstruct palaeoenvironmental changes spanning Marine Isotope Stages (MIS) 3 to 1. Using optically stimulated luminescence (OSL) dating, low field magnetic susceptibility (χlf), and mass ...

Late‐Holocene evolution of a small Sub‐Arctic glacier, Gljúfurárjökull (Tröllaskagi, northern Iceland)

Boreas, EarlyView.
Gljúfurárjökull, located on the Tröllaskagi Peninsula in northern Iceland, is a small glacier approximately 3.8 km in length. This study analyses the glacier's evolution through a combination of methods including: (i) geomorphological mapping, (ii) Cosmic‐Ray Exposure (CRE) dating, (iii) lichenometry and (iv) palaeoglacier reconstruction (volume ...

JWST/NIRCam Paβ Narrowband Imaging Reveals Ordinary Dust Extinction for Hα Emitters within the Spiderweb Protocluster at z = 2.16

The Astrophysical Journal
We combine JWST/NIRCam and Subaru/MOIRCS dual Pa β +H α narrowband imaging to trace the dust attenuation and the star formation activities of a sample of 43 H α emitters at the core of one of the most massive and best-studied clusters in formation at the

Coastal evolution, environmental change and carbon storage in the Thung Prong Thong Mangrove, eastern Gulf of Thailand

Boreas, EarlyView.
Palaeoenvironmental records along the eastern coast of Thailand remain sparse, with only a few studies attempting to reconstruct past climatic and environmental conditions. However, additional palaeoenvironmental, palaeoclimatic and sea‐level records are needed to improve our understanding of coastal evolution and local environmental changes.

Wavelet coherence analysis of Atlantic hurricanes and cosmic rays [PDF]

Geofísica Internacional, 2008
In order to sustain previous results regarding the Correlational Analysis between Tropical Cyclones and Cosmophysical phenomena, namely Galactic Cosmic Rays (CR) and Solar Activity (SS), we extend here such analysis by means of the Coherence Morlet ...

More than 30 000 volunteers involved in identification of tiny rare interstellar dust particle candidates collected by the Stardust mission

Heidelberger Jahrbücher Online, 2017
The NASA Stardust mission returned the first tiny samples of interstellar dust from beyond the borders of our solar system. This region is almost devoid of matter and the interstellar dust particles floating through our solar system are extremely rare ...
