What it takes to be a "Good" correctional officer: Occupational fitness and co-worker expectations from the perspective of correctional officer recruits in Canada.

Selecting individuals who are the right "fit" for correctional work is not an easy task for prison administrators because of the dangerous nature of correctional work and the centrality of prison employees in the prisoner's rehabilitation process. We analyze fitness for correctional work from the employee's perspective, complementing the scholarship focused on the employer's view. We measure occupational fitness in terms of co-worker expectations, analyzing 104 semi-structured interviews conducted with Federal Canadian Correctional Officer recruits in 2018/2019.

Independent host- and bacterium-based determinants protect a model symbiosis from phage predation.

Bacteriophages (phages) are diverse and abundant constituents of microbial communities worldwide, capable of modulating bacterial populations in diverse ways. Here, we describe the phage HNL01, which infects the marine bacterium Vibrio fischeri. We use culture-based approaches to demonstrate that mutations in the exopolysaccharide locus of V.

"It Is Difficult to Always Be an Antagonist": Ethical, Professional, and Moral Dilemmas as Potentially Psychologically Traumatic Events among Nurses in Canada.

Aims: We explore social and relational dynamics tied to an unexplored potentially psychologically traumatic event (PPTE) that can impact nurses' well-being and sense of their occupational responsibilities: namely, the moral, ethical, or professional dilemmas encountered in their occupational work.

Design: We used a semi-constructed grounded theory approach to reveal prevalent emergent themes from the qualitative, open-ended component of our survey response data as part of a larger mixed-methods study.

Methods: We administered a national Canadian survey on nurses' experiences of occupational stressors and their health and well-being between May and September 2019.

Development of a 3-Dimensional Middle Ear Model to Teach Anatomy and Endoscopic Ear Surgical Skills.

Mastery of ear anatomy and otologic surgical skills is challenging for trainees, and educational resources are limited. Advancements in 3-dimensional (3D) printing have enabled the construction of complex microscopic models. Otoendoscopy provides excellent visualization and has been shown to enhance anatomic learning.

Drawing for Visual Communication in Medicine: A Novel Pilot Course for Senior Medical Students.

Objective: Visual aids such as drawings have been reported to improve patient comprehension, retention, and adherence. We sought to determine the feasibility of teaching live drawing for clinical communication to medical students.

Design: We designed a course to teach basic drawing skills and visual communication of health information to senior medical students.

HbtR, a Heterofunctional Homolog of the Virulence Regulator TcpP, Facilitates the Transition between Symbiotic and Planktonic Lifestyles in Vibrio fischeri.

The bioluminescent bacterium forms a mutually beneficial symbiosis with the Hawaiian bobtail squid, , in which the bacteria, housed inside a specialized light organ, produce light used by the squid in its nocturnal activities. Upon hatching, juveniles acquire from the seawater through a complex process that requires, among other factors, chemotaxis by the bacteria along a gradient of -acetylated sugars into the crypts of the light organ, the niche in which the bacteria reside. Once inside the light organ, transitions into a symbiotic, sessile state in which the quorum-signaling regulator LitR induces luminescence.

Ambient pH Alters the Protein Content of Outer Membrane Vesicles, Driving Host Development in a Beneficial Symbiosis.

Outer membrane vesicles (OMVs) are continuously produced by Gram-negative bacteria and are increasingly recognized as ubiquitous mediators of bacterial physiology. In particular, OMVs are powerful effectors in interorganismal interactions, driven largely by their molecular contents. These impacts have been studied extensively in bacterial pathogenesis but have not been well documented within the context of mutualism.

Immunization Mandates, Vaccination Coverage, and Exemption Rates in the United States.

Background: Vaccination coverage among children entering kindergarten in the United States is high, but interstate variations exist. The relationship between state immunization laws and vaccination coverage has not been fully assessed. We evaluated associations of state laws on both measles, mumps, and rubella (MMR) and diphtheria, tetanus, and pertussis (DTaP) vaccination coverage and exemptions to school immunization requirements.

Survival of Anaerobic Fe Stress Requires the ClpXP Protease.

strain MR-1 is a versatile bacterium capable of respiring extracellular, insoluble ferric oxide minerals under anaerobic conditions. The respiration of iron minerals results in the production of soluble ferrous ions, which at high concentrations are toxic to living organisms. It is not fully understood how Fe is toxic to cells anaerobically, nor is it fully understood how is able to resist high levels of Fe Here we describe the results of a transposon mutant screen and subsequent deletion of the genes and in , which demonstrate that the protease ClpXP is required for anaerobic Fe resistance.

Structure, function, and control of the human musculoskeletal network.

The human body is a complex organism, the gross mechanical properties of which are enabled by an interconnected musculoskeletal network controlled by the nervous system. The nature of musculoskeletal interconnection facilitates stability, voluntary movement, and robustness to injury. However, a fundamental understanding of this network and its control by neural systems has remained elusive.

Storm Water Management Model: Performance Review and Gap Analysis.

The storm water management model (SWMM) is a widely used tool for urban drainage design and planning. Hundreds of peer-reviewed articles and conference proceedings have been written describing applications of SWMM. This review focuses on collecting information on model performance with respect to calibration and validation in the peer-reviewed literature.

A Ferrous Iron Exporter Mediates Iron Resistance in Shewanella oneidensis MR-1.

Shewanella oneidensis strain MR-1 is a dissimilatory metal-reducing bacterium frequently found in aquatic sediments. In the absence of oxygen, S. oneidensis can respire extracellular, insoluble oxidized metals, such as iron (hydr)oxides, making it intimately involved in environmental metal and nutrient cycling.
