Duplicitous Remembrance: Confessing Self‐Deception with Augustine
Modern Theology, EarlyView.Abstract While self‐deception has long been a topic of interest in psychology and analytic philosophy—and increasingly in the academic study of theology and religion—direct engagement with Augustine on self‐deception remains underexplored in contemporary scholarship.

, 2005 Two changes in recording the sunspot record have occurred in recent years. First, in 1976, the longer-than-100-yr daily photographic record of the Royal Greenwich Observatory (RGO), used for determination of numbers and positions of sunspot groups and ...

A digital method to calculate the true areas of sunspot groups
, 2014 The areas of sunspots are the most prominent feature of the development of sunspot groups. Since the size of sunspot areas depend on the strength of the magnetic field, accurate measurements of these areas are important.

Long‐term stability of transcrestal sinus augmentation
Periodontology 2000, EarlyView.Abstract Transcrestal sinus augmentation has emerged as a minimally invasive alternative to lateral window techniques for vertical bone augmentation in the edentulous maxilla. Since its early introduction and modification over the last several decades, this technique has demonstrated predictable outcomes for implant placement in regions with limited ...

Teacher Perspectives of Student Engagement in Data Practice Instruction: Two Classroom Conditions
School Science and Mathematics, EarlyView.ABSTRACT This study examines high school science teachers' perceptions of student engagement in data practices across two instructional contexts: a scaffolded, student‐centered environment using the Science Practices Innovation Notebook (SPIN) and a business‐as‐usual (BAU) teacher‐led investigation.

Sunspot areas and tilt angles for solar cycles 7-10
, 2015 Aims. Extending the knowledge about the properties of solar cycles into the past is essential for understanding the solar dynamo. This paper aims to estimate areas of sunspots observed by Schwabe in 1825−1867 and to calculate the tilt angles of sunspot ...

Measurements of Sunspot Group Tilt Angles Based on SOHO/MDI and SDO/HMI Magnetograms
The Astrophysical JournalThe tilt angle of sunspot groups plays a crucial role in solar dynamo models for the generation of the poloidal field, yet the statistical properties of the tilt angle are not fully comprehended.
