Log files and an independent gantry inclinometer were used to derive the irradiation parameters through a series of test plans. The in-house DSMSPArc was established by fitting both mechanical and irradiation parameters. Eight SPArc plans from different disease sites were used to validate the model’s accuracy. To assess the treatment efficiency improvement, the DSMSPArc was used to simulate the SPArc …

A Direct Machine-Specific Parameters Incorporated Spot-Scanning Proton Arc (Sparc) Algorithm, Gang Liu, Lewei Zhao, Di Yan, Xiaoqiang Li, Xuanfeng Ding

Conference Presentation Abstracts

Purpose: To address the challenges of generating a deliverable and efficient spot-scanning proton arc (SPArc) plan for a proton therapy system. We developed a novel SPArc optimization algorithm (SPArcDMSP) by directly incorporating machinespecific parameters such as mechanical constraints and delivery sequence. Method and Material: A SPArc delivery sequence model (DSMarc) was built based on the machine-specific parameters of the prototype arc delivery system IBA ProteusONEt. The SPArcDMSP resamples and adjusts each control point’s delivery speed based on the DSMarc calculation through the iterative approach (Fig1). Users could set the expected delivery time and gantry max acceleration as a mechanical constraint …

The Politics Of Temporary Protection Schemes: The Role Of Mexico’S Tvrh In Reproducing Precarity Among Central American Migrants, Carla Angulo-Pasel

Political Science Faculty Publications

Using Mexico’s Tarjeta de Visitante por Razones Humanitarias (TVRH) as a primary case study, this article examines how states can use temporary protection schemes as border security measures while claiming to provide protection. Although the TVRH offers a legal pathway and status to move within Mexico, it equally restricts certain rights due to its temporary nature. It becomes a form of differential inclusion by which the state has the right to be able to “exclude and define the limits” of a particular population but also claim inclusion on humanitarian grounds. Despite the claim of protecting migrants, the application of this …

Cultural Adaptation Profiles Among Mexican-Descent Latinxs: Acculturation, Acculturative Stress, And Depression., Mark W. Driscoll, Lucas Torres

Psychology Faculty Research and Publications

Objectives: Person-centered analysis was used to examine profiles of acculturation and acculturative stress among Mexican-descent adults in relation to depression. It was hypothesized that identified profiles would support multiple acculturation styles, that acculturation profiles would differentially relate to acculturative stress dimensions, and that those profiles with greater Latinx acculturation and lower acculturative stress would report less severe depression. Method: Mexican-descent Latinx adults (n = 230) completed self-report measures of Latinx and Anglo acculturation, acculturative stress, and depression symptom severity. Latent profile analysis was used to derive acculturation–acculturative stress profiles. Results: Three distinct profiles emerged. One profile was notable for …

The Deep Architecture Of American Covid-19 Tort Reform 2020-21, Anthony J. Sebok

Articles

The rapid emergence of the COVID-19 pandemic produced massive state actions to protect in public health through the exercise of the police powers by local, state and national governments. In the United States there were calls early in the crisis to exercise the state’s power over tort law: As early as April 2020, the American Tort Reform Association published a White Paper, Responding to the Coming Lawsuit Surge that called for “reasonable constraints on . . . lawsuits that pose an obstacle to the coronavirus response effort, place businesses in jeopardy, and further damage the economy.”

Perceptions Of Secondary Music Educators On The Transition To, And First Years Of The Every Student Succeeds Act, Thomas Rizzuto

Theses & Dissertations

The Every Student Succeeds Act (ESSA) of 2015 has the potential to be important for American music education. Unlike its predecessor, No Child Left Behind (NCLB), ESSA mentions music by name as one of the components of a “well-rounded education,” rather than including it under the arts. However, there is much that is unknown about ESSA and how it pertains to music education. The purpose of this qualitative case study was to better understand the perceptions of music educators on the transition to and the first years of ESSA. The primary source of data included 18 semi-structured interviews with secondary …

The Gay Agenda: Being Accepted In Children’S Media, Tiffany Wells

Honors College Theses

For many LGBTQ+ children, there is a lack of representation of their identities in the television shows they see growing up. We turn to objects, like television characters, to help “find our way,” which becomes limited for individuals who are part of the minority (Ahmed 1). When television shows reflect a variety of lived experiences, they can increase cultural competence in their viewers. While LGBTQ+ representation in children’s media has increased, it is still difficult to implement such representation. This thesis we will discuss three shows, Gravity Falls, Steven Universe, and The Owl House, that have struggled with the implementation …

Rescuecastr: Exploring Photos And Live Streaming To Support Contextual Awareness In The Wilderness Search And Rescue Command Post, Brennon Jones, Anthony Tang, Carman Neustaedter

Research Collection School Of Computing and Information Systems

Wilderness search and rescue (WSAR) is a command-and-control activity where a Command team manages field teams scattered across a large area looking for a lost person. The challenge is that it can be difficult for Command to maintain awareness of field teams and the conditions of the field. We designed RescueCASTR, an interface that explores the idea of deploying field teams with wearable cameras that stream live video or sequential photos periodically to Command that aid contextual awareness. We ran a remote user study with WSAR managers to understand the opportunities and challenges of such a system. We found that …

The Politics Of Bank Opacity, Heng Yue, Liandong Zhang, Qinlin Zhong

Research Collection School Of Accountancy

The distribution of power in the political system shapes the financial reporting opacity of banks. Specifically, banks located in states with senators on the Senate Banking Committee (BC senators) have greater abnormal loan loss provisions than banks in other states. The result is stronger for larger banks and banks with higher risk. In addition, BC senators have a negative effect on the likelihood of banks in their home states receiving enforcement actions, and, more importantly, this effect is stronger for more opaque banks. These findings suggest that politicians, regulators, and banks use opaque financial reporting to facilitate regulatory forbearance. Moreover, …

Executive Function Moderates The Effect Of Reappraisal On Life Satisfaction: A Latent Variable Analysis, Wei Xing Toh, Hwajin Yang

Research Collection School of Social Sciences

Emotion regulation strategies, such as reappraisal and suppression, have been shown to dissimilarly affect life satisfaction. Specifically, reappraisal is linked to higher life satisfaction, while suppression is associated with lower life satisfaction. Less is known, however, about the potential moderators of these established relations. Given that reappraisal and suppression are contingent, in part, on executive function (EF), which comprises a group of adaptive, goal-orientated control processes (i.e., inhibitory control, working memory, and shifting), we explored whether different components of EF could moderate the impact of reappraisal and suppression on life satisfaction. Using latent moderated structural equation analyses, we found that …

Borderline Personality Traits And Romantic Relationship Dissolution, Kenneth Tan, Samantha H. Ingram, Laura Anne Lau, Susan South

Research Collection School of Social Sciences

Many studies have found that borderline personality disorder (BPD) is associated with romantic relationship instability, with relationship dissolution being a recurring theme. Scant research, however, has examined the dissolution strategies and post-breakup outcomes for individuals with elevated levels of borderline traits. Findings from two studies revealed that there was an association between BPD criteria and tendency to employ less adaptive dissolution strategies when terminating a relationship. Furthermore, elevated levels of BPD traits were associated with less self-concept clarity and more unwanted pursuit of ex-partners. These findings both provide insight into how individuals with BPD traits experience relationship dissolution and suggest …

Aestheticized Temples, Rationalized Affects: Sacred Modernities And The Micro-Regulation Of Hinduism In Singapore, Orlando Woods, Lily Kong

Research Collection School of Social Sciences

This paper develops the idea of “sacred modernities” to explore how the state- led regulation of religion shapes religious communities and religious subjects therein. Sacred modernities define the ways in which sacredness is understood and engaged with under conditions of secular modernity, and in particular, how sacredness is experienced within a context of micro-regulated religious space. We illustrate these ideas through an empirical examination of how Singapore’s Hindu community engages with the idea of sacredness in and through the temple. By contrasting the experiences of Singaporean and non-Singaporean Hindus, we argue that Singapore’s temples offer an aestheticized experience of the …

Socializing Targets Of Older Adults’ Sns Use: Social Strain Mediates The Relations Between Older Adults’ Sns Use With Friends And Well-Being Outcomes, Yue Qi Germaine Tng, Hwajin Yang

Research Collection School of Social Sciences

Studies have yielded mixed findings regarding the relation between older adults’ social networking site (SNS) use and well-being. Drawing on socioemotional selectivity theory, we sought to examine whether older adults’ SNS use with different socializing targets (i.e., family vs friends) would differentially predict global, social, and mental well-being outcomes indexed by life satisfaction, loneliness, and depressive symptoms, respectively. Furthermore, we examined whether social support and social strain would mediate, in parallel, the relations between SNS use and well-being outcomes. We recruited healthy, community-dwelling older adults (ages 60–93 years, N = 69). Using the PROCESS macro, we found that SNS use …

Estimating E-Scooter Traffic Flow Using Big Data To Support Planning For Micromobility, Feng Chen, Junfeng Jiao, Haofeng Wang

Research Collection College of Integrative Studies

Dockless e-scooter sharing, as a new shared micromobility service, has quickly gained popularity in recent years. In this paper, we present a practical approach to estimating e-scooter flow patterns without knowing the actual routes taken by the e-scooter riders. Our method takes advantage of a huge open dataset that contains the origins and destinations of millions of trips. We show that our models can help cities better support the emerging shared micromobility service. The additional information generated in the modeling process can also be useful for a more refined analysis of e-scooter trips.
