      The Civil Rights Act of 1964 has served as an influential legal framework for addressing intentional (disparate treatment) and unintentional (disparate impact) discrimination. While philosophical and methodological discussions of Title VI and Title VII are well articulated in the legal scholarship, the disparate impact approach--a method for evaluating unintended racialized differences in outcomes resulting from facially neutral policies or practices--remains an underutilized conceptual and methodological framework in assessment literature. In this article, we argue that the burden-shifting heuristic used by entities such as the Office for Civil Rights to redress disparate impact is a valuable approach in evaluating fairness of writing assessment practices. In demonstrating an application of the burden-shifting approach at one university writing program, we discuss the value of the proposed integrative framework and point to remaining questions regarding sampling concerns--group identification, group stability, and intersectionality.

              We hope this special issue adds to the body of knowledge created by the writing studies community with respect to the opportunities that can be created when assessment is seen in terms of the creation of opportunity structure. This hope is accompanied by a reminder of our strength as we annually encounter approximately 48.9 million students in public elementary and secondary schools 20.6 million students in postsecondary institutions (Snyder & Dillow, 2015). Our influence is remarkable as we touch the lives of many, one student at a time.

                Introduction: Performance on patient satisfaction surveys is becoming increasingly important for practicing emergency physicians and the introduction of learners into a new clinical environment may impact such scores. This study aimed to quantify the impact of introducing fourth-year medical students on patient satisfaction in two university-affiliated community emergency departments (EDs).

                Methods: Two community-based EDs in the Indiana University Health (IUH) system began hosting medical students in March 2011 and October 2013, respectively. We analyzed responses from patient satisfaction surveys at each site for seven months before and after the introduction of students. Two components of the survey, “Would you recommend this ED to your friends and family?” and “How would you rate this facility overall?” were selected for analysis, as they represent the primary questions reviewed by the Center for Medicare Services (CMS) as part of value-based purchasing. We evaluated the percentage of positive responses for adult, pediatric, and all patients combined.

                Results: Analysis did not reveal a statistically significant difference in the percentage of positive response for the “would you recommend” question at both clinical sites with regards to the adult and pediatric subgroups, as well as the all-patient group. At one of the sites, there was significant improvement in the percentage of positive response to the “overall rating” question following the introduction of medical students when all patients were analyzed (60.3% to 68.2%, p=0.038). However, there was no statistically significant difference in the “overall rating” when the pediatric or adult subgroups were analyzed at this site and no significant difference was observed in any group at the second site. 

                Conclusion: The introduction of medical students in two community-based EDs is not associated with a statistically significant difference in overall patient satisfaction, but was associated with a significant positive effect on the overall rating of the ED at one of the two clinical sites studied. Further study is needed to evaluate the effect of medical student learners upon patient satisfaction in settings outside of a single health system.

                  Routine inspection and monitoring of railway tracks and facilities is an important task to ensure operational safety. The existing standard manual and rail vehicle based investigation are substantially time consuming and inaccurate. UAV-based autonomous monitoring and inspection technology has shown great potential in many fields and industries but it has been rarely explored in railway transit systems. UC Berkeley California Partners for Advanced Transportation Technologies   (PATH) in partnership with Bay Area Rapid Transit (BART) investigated  the application of unmanned aerial vehicles (UAV) and autonomous rail-based vehicles for autonomous routine inspection of the  BART rail system, as well as rapid assessment of the BART system in case of emergency (train derailment, criminal events, earthquake, fire, and chemical leakage). The UAVs may also be utilized to monitor areas of interest, people or objects within BART’s system and provide real-time visual and location information regarding where the events occur. The primary purpose of the UAV@BART application is to reduce human labors on routine maintenance tasks, and improve operational safety and personnel security by utilizing UAV technologies in BART system inspection and monitoring.

                    A variety of phase transitions have been found in two-dimensional layered materials, but some of their atomic-scale mechanisms are hard to clearly understand. Here, we report the discovery of a phase transition whose mechanism is identified as interlayer sliding in lead iodides, a layered material widely used to synthesize lead halide perovskites. The low-temperature crystal structure of lead iodides is found not 2H polytype as known before, but non-centrosymmetric 4H polytype. This undergoes the order-disorder phase transition characterized by the abrupt spectral broadening of valence bands, taken by angle-resolved photoemission, at the critical temperature of 120 K. It is accompanied by drastic changes in simultaneously taken photocurrent and photoluminescence. The transmission electron microscopy is used to reveal that lead iodide layers stacked in the form of 4H polytype at low temperatures irregularly slide over each other above 120 K, which can be explained by the low energy barrier of only 10.6 meV/atom estimated by first principles calculations. Our findings suggest that interlayer sliding is a key mechanism of the phase transitions in layered materials, which can significantly affect optoelectronic and optical characteristics.
