Background Procedural sedation and analgesia (PSA) is considered a core competency in emergency medicine as patients present to the Emergency Centre (EC) on an unscheduled basis, often complex complaints that necessitate emergent management (1). Previous evidence has consistently shown that procedural sedation and analgesia(PSA) in the EC in the paediatric population, even the very young, is safe if appropriate monitoring is performed and appropriate medications are used (2–5). The aim of the study was to describe the indications for PSA in the paediatric EC population, the fasting status of paediatric patients undergoing PSA, and the complications observed during PSA in a single Western Cape emergency centre. Methods A retrospective, descriptive study was conducted at Mitchells Plain Hospital, a district-level hospital situated in Mitchells Plain, Cape Town. All paediatric patients younger than 13 years of age who presented to the EC and received PSA during the study period (December 2020 – April 2021) were included in the study. Data was extracted from a standardised PSA form and simple descriptive statistics were used. Results A total of 116 patients (70,7% male) were included: 13 infants (<1 year of age) 48 young children (1-5 years of age) and 55 older children (5-13 years of age). There were only 2 (1,7%) complications documented, both of which were vomiting and did not require admission. The most of patients received ketamine (93,1%). The standardised PSA form was completed in 49,1% of cases. Indications for PSA included burns debridement (11,2%), suturing (17,2%), fracture reduction (23,3%), lumbar punctures (31,9%) and others (27,6%). The indications for PSA varied between the different age groups. Conclusion The study findings are in accordance with previous international literature. Emergency Centre PSA in the paediatric populations did not show an increase in interventions or complications, despite the fasting status (6). Safe, timely PSA with minimal pain and unnecessary suffering can become the norm in Emergency Medicine practice in South Africa.

We introduce an alternative method for open-world scene generation. In this thesis, Graph-based Wave Function Collapse (GWFC) is integrated with Space Colonization Algorithm (SCA) and used to place objects in an unstructured 3D environment. This combined algorithm, Space Colonization Graph-based Wave Function Collapse (SC-GWFC), leverages the constraint-based capabilities of GWFC and the ability of SCA to populate arbitrary 3D volumes. We demonstrate that objects of variable scale can be successfully used with SC-GWFC. Since this algorithm is run in an interactive environment, we demonstrate iterative modifications to a partially complete scene and incorporate PCG into a scene editing process. As part of the implementation, we also introduce our Scene Modeling Application for rendering and editing 3D scenes. This modeling application allows for editing and viewing constraints for our SC-GWFC scene generator. We evaluate the performance characteristics of SC-GWFC in the Scene Modeling Application to demonstrate that SC-GWFC can be used interactively. Through the application, users can specify adjacency requirements for objects, and SC-GWFC will attempt to place objects in patterns that respect these rules. We demonstrate the ability to place up to 5000 items on a terrain using our proposed SC-GWFC technique.

As video games increase in complexity and length, the use of automatic, or procedural, content generation has become a popular way to reduce the stress on game designers. However, the usage of procedural generation has certain consequences; in many instances, what the computer generates is uncertain to the designer. The intent of this thesis is to demonstrate how procedural generation can be used to intentionally affect the embedded randomness of a game system, enabling game designers to influence the level of uncertainty a player experiences in a nuanced way. This control affords game designers direct control over complex problems like dynamic difficulty adjustment, pacing, or accessibility. Game design will be examined from the perspective of uncertainty and how procedural generation can be used to intentionally add or reduce uncertainty. Various procedural generation techniques will be discussed alongside the types of uncertainty, using case studies to demonstrate the principles in action.

No / The rise of reassurance policing in the UK, informed by ideas drawn from a Signal Crimes Perspective, replaced a narrow focus on controlling crime with a broader emphasis on communicating security. This paper provides a sympathetic critique of dominant assumptions implied in this policy shift concerning the reassurance function of policing. Important in these theoretically informed policy debates is the idea that the police and their partners, through symbolic communications, can influence the extent to which individuals perceive that order and security exist within urban spaces. The paper draws on research findings to illustrate the contrasting ways visible signifiers of crime and formal controls are received and interpreted by diverse audiences. It challenges assumptions about the impact of criminal activities upon perceptions of safety and contributes insights into the unintended effects of formal controls that have implications for our understanding of local social order.

Telecommuting is a significant workplace innovation that allows an increasing portion of the work force to work from home or work at a location remote from the central workplace at least one-day a week. Previous studies (Bélanger, 1999; Pinsonneault & Boisvert, 2001; Potter, 2003) have outlined that the reasons for the growth of this phenomenon are found in its perceived benefits for both the telecommuter and their employer: improved productivity, organizational loyalty and belonging, job satisfaction, savings of office space, increased flexibility, improved employee morale and employee retention and attraction. Telecommuting literature has provided models and theories about telecommuting concentrating mainly on the telecommuter's experiences and perspective. However, the ramifications of this practice have a broad range of potential impacts not only on the telecommuter, but also other parties in the work unit. Despite the tremendous growth in telecommuting, relatively few empirical studies (Duxbury & Neufield, 1999; Golden, 2007; Watson-Fritz, Narasimhan, and Rhee, 1998) have directly examined the creeping affect and effect of the telecommuting challenges on others in the work unit. Few studies (Bailey & Kurland, 2002; Cooper & Kurland, 2002; Golden, 2007; McCloskey & Igbaria, 2003) have investigated it from the non-telecommuters' perspective and how it affects their work outcomes and their attitudes More importantly, no earlier studies were found that had ever investigated the effects of the telecommuting arrangement on the non-telecommuter from the organizational justice perspective, and how this affects the non-telecommuter's job satisfaction. This study empirically examined the affects and effects of telecommuting on non-telecommuters, and within that context, examined the extent to which organizational justice perspectives affected job satisfaction. Major findings of the study revealed that : (a) the accessibility of the telecommuter is key, even if they are working offsite, (b) job type/position plays an important role in the selection process or in some non-telecommuters' decision to opt out of telecommuting, (c) there was lack of awareness of a formal telecommuting policy or understanding of how the policy was applied, (d) selection procedures can be biased and unfair, and (e) some non-telecommuters experienced envy and jealousy, frustration, resentment, anxiety, unfairness and anger towards telecommuting colleagues. The results of the study also revealed that interpersonal/interactional, and distributive justice both explained the statistically significant variance in non-telecommuters' job satisfaction. However, interpersonal/interactional justice (which focuses on the quality of interpersonal treatment individuals receive) explained a stronger statistically significant variance in the job satisfaction of non-telecommuters. / Ph.
