The Scope Of Numeracy After Five Years, H. L. Vacher, Dorothy Wallace
Numeracy
The purpose of this editorial is to provide an efficient way for readers and potential authors to see (a) what type of papers are published in this journal and (b) what subjects are appropriate. The editorial consists mainly of about a dozen pages of tables including live links to the papers’ access/abstract pages to facilitate easy browsing. In the first table, the 85 papers that have been published in the journal’s first five years are classified into: review papers; research papers; case studies; essays; book reviews; columns; and editorials about the journal. In the second table, the papers are inventoried …

Our understanding of tephra depositional processes is significantly improved by high-resolution ground-penetrating radar (GPR) data collected at Cerro Negro volcano, Nicaragua. The data reveal three depositional regimes: (1) a near-vent region on the cone itself, where 10 GPR radargrams collected on the western flank show quantifiable differences between facies formed from low energy normal Strombolian and higher energy violent Strombolian processes, indicating imaging of scoria cone deposits may be useful in distinguishing eruptive style in older cones where the proximal to distal tephra blanket has eroded away; (2) a proximal zone in which horizons identified in crosswind profiles collected at …
