#UsToo debuted at the 39th Annual Conference of the North American Drama Therapy Association. It was written and performed by the author as an autoethnographic therapeutic theatre performance investigating her experiences with sexual assault and harassment perpetrated by members of the drama therapy community. This article includes an annotated version of the script with a discussion on form, content, aesthetic choices and embodiment. This article concludes with a synthesis of authorial learnings and outcomes throughout the devising, rehearsal and performance processes.

Abstract Evaluating Electrical Submersible Pumps (ESPs) [SS1] [NA2] run-lives and performance in unconventional well environments is challenging due to many different factors -including the reservoir, well design, and production fluids. Moreover, reviewing the run-lives of ESPs in a field can be rather complex since the run-life data is incomplete. Often ESPs are pulled while they are still operational, or the ESP has not been allowed to run until failure. These are some of the complications that arise when gauging ESP performance. A large dataset of ESP installs was assessed using Kaplan-Meier survival analysis for the North American unconventional application to better understand those factors that may affect ESP run lives. The factors were studied including but are not limited to the following: Basin and producing formation Comparing different ESP component types such pumps and motors, and new or used ESP components Completion intensity of the frac job (lb/ft of proppant) Kaplan-Meier survival analysis is one of the commonly used methods to measure the fraction or probability of group survival after certain time periods because it accounts for incomplete observations. Using Kaplan-Meier analysis generates a survival curve to show a declining fraction of surviving ESPs over time. Survival curves can be compared by segmenting the runlife data into buckets (based on different factors), therefore to analyze the statistical significance of each and how they affect ESP survivability. Kaplan-Meier analysis was performed on the aforementioned dataset to answer these questions in order to better understand the factors that affect ESP runlives in North American unconventional plays. This work uses a unique dataset that encompasses several different ESP designs, with the ESPs installed in different North American plays. The observations and conclusions drawn from it, by applying survival analysis, can help in benchmarking ESP runtimes and identifying what works in terms of prolonging ESP runlife. The workflow is also applicable to any asset in order to better understand the drivers behind ESP runlife performance.

A Performance

Through a reflective account of the process by which William Richard Waldron’s Lizzie Leigh was staged by the Theatre Caucus at the 2018 North American Victorian Studies Association conference held in St Petersburg, Florida, I hope to present a picture of what it might mean to figure scholarship as an act of embodiment through performance as both a stimulus for and a mode of inquiry. Towards that end, I offer a process narrative that tracks the selection, editing, infrastructure planning, rehearsal, and performance of the play in an effort to capture the intentional, inadvertent, and retrospective avenues of inquiry that emerged through that process, with an emphasis on tracking as fully as possible the performance history of the play, of which the North American Victorian Studies Association performance became a part. In addition to documenting the performance history of the play in Victorian Britain, I will also document the career of the play’s author in relation to the changes in decade and in venue of performances of the play in order to suggest the appeal and staying power of an under-valued piece of Victorian theatrical culture that still can speak to audiences today.

Practical Implications

Purpose Sustainability performance in higher education is often evaluated at a generalized large scale. It remains unknown to what extent campus efforts address regional sustainability needs. This study begins to address this gap by evaluating trends in performance through the lens of regional environmental characteristics. Design/methodology/approach Four sustainability metrics across 300 North American institutions are analyzed between 2005 and 2014. The study applies two established regional frameworks to group and assess the institutions: Commission on Environmental Cooperation Ecoregions and WaterStat (water scarcity status). Standard t-tests were used to assess significant differences between the groupings of institutions as compared to the North American study population as a whole. Findings Results indicate that all institutions perform statistically uniformly for most variables when grouped at the broadest (Level I) ecoregional scale. One exception is the Marine West Coast Forest ecoregion where institutions outperformed the North American average for several variables. Only when institutions are grouped at a smaller scale of (Level III) ecoregions do the majority of significant performance patterns emerge. Research limitations/implications This paper demonstrates an ecoregions-based analytical approach to evaluating sustainability performance that contrasts with common evaluation methods in the implementation field. This research also identifies a gap in the literature explicitly linking ecological sub-regions with their associated environmental challenges and identifies next research steps in developing defensible regional targets for applied sustainability efforts. Practical implications The practical implications of this research include the following: substantive changes to methodologies for rating sustainability leadership and performance, a framework that incentivizes institutions to frame sustainability efforts in terms of collaborative or collective impact, a framework within which institutions can meaningfully prioritize efforts, and a potential shift toward regional impact metrics rather than those focused solely on campus-based or generalized targets. Originality/value The authors believe this to be the first effort to analyze North American higher education sustainability performance using regional frameworks.

Practical Task

Two experiments studied the relation of illumination level and practical task performance, and the effects of age. Performance improved with illumination and declined with age. The North American illumination standards seem adequate but not excessive.
