Moral Implications of Emergency Department Crowding
Emergency Department (ED) crowding, defined as "an extreme volume of patients in ED treatment areas, forcing the ED to operate beyond its capacity" has become a public health crisis in the United States. ED crowding can lead to compromised care which threatens the moral values medicine has been …

The role of crowding in parallel search
Crowding is the deleterious effect of nearby objects on object recognition in the peripheral (Pelli, 2008). In three visual search experiments the contribution of visual crowding to reaction time performance in an efficient search task was evaluated by varying the factors known to affect the …

Understanding bus passenger crowding through origin destination inference
… aspect of the transit passenger experience. Crowding can significantly decrease passenger comfort and disrupt service delivery, causing passenger travel times to increase and even resulting in passengers being unable to board an arriving vehicle. Reducing crowding is especially important to …

Perceived Crowding: Consumers’ Lived Experiences of a Tourist Destination
Crowding, driven by population growth, urbanisation, industrialisation, and tourism, extends beyond physical density to encompass psychological, social, and cultural dimensions. This thesis with publications, integrates prospective and retrospective perspectives to offer a more comprehensive …

Maxillary Incisor Crown Form and Crowding in Adolescent Orthodontic Patients
<p>Dental crowding occurs when the mesiodistal tooth crown widths exceed the space available in the dental arch for proper alignment. Previous research dealing with this common orthodontic problem has measured mesiodistal (MD) tooth widths or <em>clinical</em> tooth height-to-width ratios from …

Effetto crowding e dislessia evolutiva: un confronto inter e intra-linguistico
Crowding is defined as the negative effect obtained by adding visual distractors around a central target which has to be identified. Some studies have suggested the presence of a marked crowding effect in developmental dyslexia (e.g. Atkinson, 1991; Spinelli et al., 2002). Inspired by Spinelli’s …

Sensing and Predicting Urban Rail Platform Crowding Using Emerging Data Sources
Rail platform crowding poses serious challenges to passenger safety, operational performance, and service quality in urban rail transit systems. This thesis investigates the short-term forecasting of platform-level crowding, focusing on enhancing prediction accuracy, spatial granularity, and …

The effects of manning level on task performance and perceived crowding
… concerning manning levels and the perception of crowding and related experiences. A new apparatus was designed and built (an HO-gauge train set) to manipulate manning level, physical constraint (using two different control designs), and cognitive load, variables suggested as important in the …

Transit Demand Estimation And Crowding Prediction Based On Real-Time Transit Data
… data to estimate transit volume and predict crowding conditions. We introduce a proactive Transit Demand Estimation and Prediction System (TraDEPS) – an approach that has the potential to prevent crowding and improve transit service, by measuring the transit activity (the number of passengers …

Impact of Childhood Obesity on Dental Crowding, Arch Shape, and Arch Width
… study explores the effects of obesity on dental crowding, arch shape, and arch width in children from age 5-17.9 with various body mass indices (BMI). Patients presenting at the University of Illinois at Chicago for their orthodontic records appointment were recruited. Patients were categorized …

Aging Changes Cell Mechanics and Dynamics with a Backbone of Cytoplasmic Crowding
Aging is a biological process that is correlated with life-altering and terminal diseases, and while the population of the elderly increases every year, the mechanism behind aging and its physical changes is not fully understood. Many aging studies traditionally focus on molecular-level changes, …

Optimising the Loading Diversity of Rail Passenger Crowding using On-Board Occupancy Data
… UK there is an annual survey of rail passenger crowding, although the measures used do not reflect coach-by-coach variations, nor do they reflect variations across the peak period. In this MPhil thesis I investigated the application of weight-based automatic passenger counting data to deliver …
