Applying the Instructional Beliefs Model to Training and Development Research and Practice

In 2011, Weber, Martin, and Myers introduced an innovative instructional model to more fully understand student outcomes within the classroom: the Instructional Beliefs Model (IBM). Results from this seminal article provided support to suggest that the IBM was a better predictor of student outcomes than previous models. Since its inception, this model has guided and informed subsequent instructional research (e.g., Goodboy & Frisby, 2014; Johnson & LaBelle, 2015; LaBelle, Martin, & Weber, 2013). While clearly applicable in the university classroom, the theoretical relationships outlined by the IBM offer transferability to additional instructional contexts: namely, training and development. Notably, there is limited visibility of empirical training and development research in communication scholarship (e.g., Stephens & Mottet, 2009), and a majority of investigations rely on case studies or needs assessment (e.g., Lucier, 2008) to forward knowledge claims. However, if the discipline is truly committed to expanding knowledge of communication within training, applicable in both academic and organizational contexts, scholars should pursue more theoretically and empirically driven research. As such, the IBM has potential to serve as an instrumental resource in forwarding more generalizable findings in training communication research. Thus, the purpose of the present explication and extension of this model is to highlight the shortcomings and strengths of applying the IBM to training and development. First, several major preceding instructional models are outlined. Second, the assumptions and tenets of the IBM are discussed at length. Throughout this overview, the theoretical underpinnings of the relationships outlined in the model, along with conceptual and operational implications for applying the IBM to a training context, are explored

Students\u27 Perceptions of Professional Short-Messaging Education in Undergraduate Courses

The popularity of short-messaging formats, like text and chat, is on the rise in the workplace with many employees preferring this style over long-form options like email. While many businesses expect employees to communicate using short messages, students may be ill-equipped to effectively use these methods due to a lack of formal training. This study sets out to understand students’ experience, confidence, and education related to professional short messaging. Results indicate a correlation between confidence and experience levels in writing text and chat messages. Further, the participants who indicated they had training on writing short messages, indicated they learned it in a business communication class. Thus, this study highlights a need for education on short messaging in the business communication classroom to increase student experience, and thus, their confidence in writing these messages

Liver Transplantation because of Acute Liver Failure due to Heme Arginate Overdose in a Patient with Acute Intermittent Porphyria

In acute attacks of acute intermittent porphyria, the mainstay of treatment is glucose and heme arginate administration. We present the case of a 58-year-old patient with acute liver failure requiring urgent liver transplantation after erroneous 6-fold overdose of heme arginate during an acute attack. As recommended in the product information, albumin and charcoal were administered and hemodiafiltration was started, which could not prevent acute liver failure, requiring super-urgent liver transplantation after 6 days. The explanted liver showed no preexisting liver cirrhosis, but signs of subacute liver injury and starting regeneration. The patient recovered within a short time. A literature review revealed four poorly documented cases of potential hepatic and/or renal toxicity of hematin or heme arginate. This is the first published case report of acute liver failure requiring super-urgent liver transplantation after accidental heme arginate overdose. The literature and recommendations in case of heme arginate overdose are summarized. Knowledge of a potentially fatal course is important for the management of future cases. If acute liver failure in case of heme arginate overdose is progressive, super-urgent liver transplantation has to be evaluated

Historic methicillin-resistant Staphylococcus aureus: expanding current knowledge using molecular epidemiological characterization of a Swiss legacy collection.

BACKGROUND: Few methicillin-resistant Staphylococcus aureus (MRSA) from the early years of its global emergence have been sequenced. Knowledge about evolutionary factors promoting the success of specific MRSA multi-locus sequence types (MLSTs) remains scarce. We aimed to characterize a legacy MRSA collection isolated from 1965 to 1987 and compare it against publicly available international and local genomes. METHODS: We accessed 451 historic (1965-1987) MRSA isolates stored in the Culture Collection of Switzerland, mostly collected from the Zurich region. We determined phenotypic antimicrobial resistance (AMR) and performed whole genome sequencing (WGS) using Illumina short-read sequencing on all isolates and long-read sequencing on a selection with Oxford Nanopore Technology. For context, we included 103 publicly available international assemblies from 1960 to 1992 and sequenced 1207 modern Swiss MRSA isolates from 2007 to 2022. We analyzed the core genome (cg)MLST and predicted SCCmec cassette types, AMR, and virulence genes. RESULTS: Among the 451 historic Swiss MRSA isolates, we found 17 sequence types (STs) of which 11 have been previously described. Two STs were novel combinations of known loci and six isolates carried previously unsubmitted MLST alleles, representing five new STs (ST7843, ST7844, ST7837, ST7839, and ST7842). Most isolates (83% 376/451) represented ST247-MRSA-I isolated in the 1960s, followed by ST7844 (6% 25/451), a novel single locus variant (SLV) of ST239. Analysis by cgMLST indicated that isolates belonging to ST7844-MRSA-III cluster within the diversity of ST239-MRSA-III. Early MRSA were predominantly from clonal complex (CC)8. From 1980 to the end of the twentieth century, we observed that CC22 and CC5 as well as CC8 were present, both locally and internationally. CONCLUSIONS: The combined analysis of 1761 historic and contemporary MRSA isolates across more than 50 years uncovered novel STs and allowed us a glimpse into the lineage flux between Swiss-German and international MRSA across time
