ABSTRACT
The structural condition of hydroelectric tunnels is important to the overall performance, safety, and longevity of generating stations. Significant effort is required to inspect, monitor, and maintain these tunnels. Photogrammetry is an effective method of collecting highly accurate visual and spatial data. However, it also presents the complex challenge of positioning a camera at thousands of difficult-to-reach locations throughout the large and varying-diameter tunnels. A semi-automated robotic camera positioning system was developed to enhance the collection of images within hydroelectric tunnels for photogrammetric inspections. A continuous spiral image network was developed to optimize the collection speed within the bounds of photography and capture-in-motion constraints. The positioning system and image network optimization reduce the time and effort required while providing the ability to adapt to different and varying tunnel diameters. To demonstrate, over 28,000 images were captured at a ground sampling distance of 0.4 mm in the 822 m long concrete-lined section of the Grand Falls Generating Station intake tunnel.
ABSTRACT
Being politically correct involves an understanding that language and behavior can affect others, and a willingness to modify or suppress those words or actions to be sensitive and tolerant toward others. At work, political correctness may manifest as refraining from sharing a risqué joke out of concern of hurting others' feelings, altering language to be gender neutral, suppressing saying something that might be considered rude or insensitive, or avoiding controversial topics altogether. As employees are increasingly entrenched in their own opinions and beliefs, prone to microaggressions, and unwilling to entertain alternate views, political correctness should be of interest to managers and organizations. Yet, little research has been devoted to its study. This oversight is problematic because, although political correctness may manifest out of a concern for others at work, its enactment is also resource intensive-potentially acting as a double-edged sword for employees. To make better recommendations to managers, we must more fully develop our understanding of this understudied phenomenon. We begin the process of developing the nomological network of political correctness by drawing from theory on self-control to examine (a) an antecedent (other orientation) to understand why employees may be motivated to be politically correct with their coworkers, (b) a mechanism (cognitive resource depletion) that explains the cost of workplace political correctness, and (c) home-based outcomes (angry and withdrawn marital behavior) that suggest political correctness may impact others outside of work. Findings across five studies shed light on why employees may be politically correct and the consequences of doing so. (PsycInfo Database Record (c) 2023 APA, all rights reserved).
