Teacher Matters: Teacher Normative Influence and Student Persistence in College

This dissertation extends the work on teacher immediacy (TI) and student persistence by using the Theory of Planned Behavior (TPB) (Ajzen, 1985) to account for variability in college student persistence. Students provided perceptions of their teachers’ immediacy behaviors using modified versions of Gorham’s (1988) TI scale. Instruction prompts of the TI scale were manipulated to create four conditions. The results from Study 1 demonstrate that TI scale prompt language has an effect on the ways participants assess their teacher’s immediacy behaviors. The results from Study 2 show that student perceptions of their teacher’s immediacy behaviors change over the course of an academic semester, such that TI is statistically higher at the end of the semester than at the beginning, as measured by collecting data at four time points. The results from both studies generally support the hypotheses and suggest the TPB accurately predicts college student persistence. However, it is unclear how TI is influencing the overall TPB structural model. In some cases, adding TI to the TPB structural models resulted in a poorer fitting model. Discussions, limitations, and future research are provided for both studies

Creating a Collaborative Network to Promote Cultures of Academic Integrity in Manitoba’s Post-Secondary Institutions

In this article, we, as representatives from several post-secondary institutions across Manitoba and British Columbia, describe how sharing knowledge and experiences across institutions has informed and enhanced academic integrity initiatives at our respective institutions. We outline how participation in provincial, national, and international teaching and learning events as a collective has informed our work in academic integrity and led to the emergence of the Manitoba Academic Integrity Network (MAIN) in May 2019. We discuss the benefits of collaborating within a provincial network and next steps for expanding the reach of the network across institutions by engaging faculty, staff, and students

False-negative SARS-CoV-2 Reverse Transcriptase Polymerase Chain Reaction (RT-PCR) is an Important Consideration for Patient Management and Infection Prevention: A Case Report from The Louisville COVID-19 Epidemiology Study

We report a case of false negative SARS-CoV-2 RT-PCR on nasopharyngeal swab. Treating clinicians and infection preventionists should maintain a high suspicion for COVID-19 in the appropriate clinical setting despite negative test results. Utilization of chest CT should be strongly considered in the diagnostic work-up for suspected COVID-19, particularly in areas with limited RT-PCR availability

Why Every Hospital Needs a COVID-19 Clinical Case Review Team

A hospital’s response to a global pandemic requires a coordinated effort to provide consistent guidance as information rapidly changes. In the early months of the COVID-19 pandemic, diagnosis and subsequent containment was challenging due to unfamiliarity with disease presentation, unknown reverse transcription-polymerase chain reaction sensitivity and inconsistent access to testing supplies. A centralized COVID-19 clinical case review team can provide guidance on test interpretation, isolation, resource coordination and more

Advanced 0.3-NA EUV lithography capabilities at the ALS

For volume nanoelectronics production using Extreme ultraviolet (EUV) lithography [1] to become a reality around the year 2011, advanced EUV research tools are required today. Microfield exposure tools have played a vital role in the early development of EUV lithography [2-4] concentrating on numerical apertures (NA) of 0.2 and smaller. Expected to enter production at the 32-nm node with NAs of 0.25, EUV can no longer rely on these early research tools to provide relevant learning. To overcome this problem, a new generation of microfield exposure tools, operating at an NA of 0.3 have been developed [5-8]. Like their predecessors, these tools trade off field size and speed for greatly reduced complexity. One of these tools is implemented at Lawrence Berkeley National Laboratory's Advanced Light Source synchrotron radiation facility. This tool gets around the problem of the intrinsically high coherence of the synchrotron source [9,10] by using an active illuminator scheme [11]. Here we describe recent printing results obtained from the Berkeley EUV exposure tool. Limited by the availability of ultra-high resolution chemically amplified resists, present resolution limits are approximately 32 nm for equal lines and spaces and 27 nm for semi-isolated lines

A Patient with Escherichia coli Bacteremia and COVID-19 Co-Infection: A Case Report for the Louisville COVID-19 Epidemiology Study

Patients with COVID-19 may have co-infections with other microorganisms. Here we report a case of a patient with an E. coli bacteremia secondary to a urinary tract infection, who experienced fevers while on active antimicrobial therapy. The patient was eventually tested for COVID-19 and found to be positive. This case emphasizes the need to suspect COVID-19 even in patients with documented bacterial infection

Characterization of the synchrotron-based 0.3-NA EUV microexposuretool at the ALS

Synchrotron-based EUV exposure tools continue to play a crucial roll in the development of EUV lithography. Utilizing a programmable-pupil-fill illuminator, the 0.3-NA microexposure tool at Lawrence Berkeley National Laboratory's Advanced Light Source synchrotron radiation facility provides the highest resolution EUV projection printing capabilities available today. This makes it ideal for the characterization of advanced resist and mask processes. The Berkeley tool also serves as a good benchmarking platform for commercial implementations of 0.3-NA EUV microsteppers because its illuminator can be programmed to emulate the coherence conditions of the commercial tools. Here we present the latest resist and tool characterization results from the Berkeley EUV exposure station
