Blip glitches in Advanced LIGO data

Blip glitches are short noise transients present in data from ground-based gravitational-wave observatories. These glitches resemble the gravitational-wave signature of massive binary black hole mergers. Hence, the sensitivity of transient gravitational-wave searches to such high-mass systems and other potential short duration sources is degraded by the presence of blip glitches. The origin and rate of occurrence of this type of glitch have been largely unknown. In this paper we explore the population of blip glitches in Advanced LIGO during its first and second observing runs. On average, we find that Advanced LIGO data contains approximately two blip glitches per hour of data. We identify four subsets of blip glitches correlated with detector auxiliary or environmental sensor channels, however the physical causes of the majority of blips remain unclear

Eve’s Two Sons: A Case Study for Biblical Drama in Worship

Barker is collaborating with Thomas Boogaart (Professor of Old Testament at Western Theological Seminary) on a Bible study guide: A New Way to Study the Old Book. The Cain and Abel story is one biblical drama the guide explores; this workshop includes three very different performances of the Genesis text

A Lion and a Donkey are Standing on the Road

This vesper worship service includes an enactment of one of the most mysterious ancient Hebrew dramas. We focus initially on this biblical text, newly translated by Tom Boogaart. We embrace the text and then respond to it with music, prayer, testimony, and more scriptures

Reclaiming the Role of Story in Worship

Our God is a storytelling God. God’s book is a rich collection of stories. God’s church is a storytelling church. This seminar is a rich collection of storytelling examples from the Bible, history, and contemporary lives, using forms as simple as a solo testimony and as complex as enacting scenes from the missionary biography Iowa Ethiopia

Story and Worship

Every church has wonderful stories—that are not being told. Barker, author of The Storytelling Church, encourages the church with reasons and ways to tell its story. His Northwestern College students will bring life to his presentation with biblical storytelling (solo and groups), testimonies, enacted prayers, video storytelling and more

Presenting Scripture Well in Worship

Join this workshop to learn from an array of performed examples (live and recorded) that model effective communication of Scripture for both individual and group presentations

From Scripture Reading to Scripture Proclamation: There’s a Difference!

Does your church look forward to the “scripture reading” part of worship? If not, why not? This seminar provides examples (live and via DVD) to explore ways to reclaim the power of presenting Scripture in worship. Participants will work with a variety of passages in a variety of ways through both solo and group efforts. Participants are also invited to prepare a short passage (memorized or to be read) for coaching

From the Vaults: Objects Relating to the Canadian Experience in Hong Kong

This article focuses on the material culture of Canadians’ experiences during and after the Battle of Hong Kong. Stories of combat, captivity, and the return home are told through this selection of personal objects now preserved in the collections of the Canadian War Museum. These artifacts highlight the particular circumstances and harsh conditions faced by prisoners of war and civilian detainees, and serve as entry points into the wider history of the battle, its aftermath and its lasting consequences. Cet article porte sur la culture matérielle des expériences des Canadiens et Canadiennes pendant et après la bataille de Hong Kong. Des histoires de combat, de captivité et de retour au pays sont racontées à travers cette sélection d’objets personnels maintenant conservés dans les collections du Musée canadien de la guerre. Ces artefacts mettent en lumière les circonstances particulières et les conditions difficiles auxquelles sont confrontés les prisonniers de guerre et les détenus civils. Ils servent aussi de points d’entrée dans l’histoire plus large de la bataille, ses répercussions et ses conséquences à long terme
