Making care audible: Musical gifts and affective reciprocity in the clinic

Feminist Anthropology, EarlyView.
Abstract In clinical settings, music therapy is frequently received as a gift—a voluntary offering that invites but does not demand participation. Drawing on ethnographic research with music therapists and patients in Canadian and American hospitals, this article examines how clinical care is co‐constituted through practices of giving, receiving, and ...

Leveraging Machine Learning to Predict Food Waste Quantity: Focusing on Military Dining Facilities as Large‐Scale Food Service Operations

Journal of Forecasting, EarlyView.
ABSTRACT Food waste reveals inefficiencies in resource use and contributes significantly to environmental pollution. In the United States, food waste accounts for the majority of total waste, with more than 50 million tons generated annually. In military units that operate large‐scale institutional food‐service facilities and generate significant food ...

Molecular Palaeontology Prospects From Exceptionally Preserved Eocene Brackish‐Water Bivalve Batissa sitakaraensis (Venerida: Corbiculidae) From Hokkaido, Japan

Geological Journal, EarlyView.
This study reports the exceptional preservation of the Eocene freshwater bivalve Batissa sitakaraensis from Hokkaido, Japan. Multimodal analyses reveal that both the aragonitic shell mineralogy and the delicate organic periostracum retain their original structural and chemical characteristics after millions of years.

Accu16S/AccuITS: Accurate and broadly applicable amplicon sequencing for absolute microbiome quantification

iMeta, EarlyView.
Traditional 16S rRNA gene and Internal Transcribed Spacer region amplicon sequencing provides only relative abundance, often leading to biased ecological interpretations. To overcome this limitation, we developed Accu16S/AccuITS, an absolute quantification method for bacterial and fungal amplicons based on synthetic internal spike‐in DNA with known ...
