Effects Of Video-Guided Group Vs. Solitary Meditation On Mindfulness And Social Connectivity: A Pilot Study, Deidre Krzanowski

All Publications

Interest in mindfulness meditation continues to grow as accumulating evidence suggests mindfulness training encourages more positive functioning. However, basic questions about the conditions best suited for realizing mindful states remain unanswered. Prominent among these is whether a group mindfulness practice setting is more effective for novice meditators than a solitary practice setting. Answering this question has assumed new urgency due to the imposition of physical distancing measures designed to stop the spread of COVID-19. In a time of limited social contact, is a simulated group practice setting better than practicing alone? This preliminary study investigated whether environmental setting impacted mindfulness …

A Heuristic Outlook On The Occupational Accidents Of Food & Beverage Staff In Hotels, Gulsah Akkus, Aytug Arslan, Merve Iscen, Burcu Isik

Journal of Global Business Insights

The labor-intensive structure, 24/7 service availability, diversity of departments including kitchens, housekeeping, and technical services, the high labor turnover ratios, along with the long working hours and shift systems inherent in accommodation establishments all play a role in the occurrence of occupational accidents (OA). Fundamental reasons underlying OA are unsafe behavior and unsafe working conditions. This study analyzes with a qualitative method the OA that occur in the food & beverage (F&B) service department of accommodation establishments from the viewpoint of employees. The study concludes that the majority of these accidents are not high risk, and generally result from unsafe …

Measuring Environmental Responsible Behavior Through Experience Quality, Perceived Value, And Tourist Satisfaction From The Perspectives Of Tourists In Natural Sites, Anil Kumar, Suman Lata

Journal of Global Business Insights

This study aims to examine environmentally responsible behavior through experience quality, perceived value, and tourist satisfaction while explaining responsible behavior of tourists towards the environment in the natural sites of Madhya Pradesh, India. The theoretical framework proposed is based on literature. Structural equation modeling (SEM) was employed using partial least squares (PLS) 3.0 software to test the model fit and hypotheses. The data was collected using random sampling from 131 tourists at these natural sites who participated in the survey through a questionnaire. The analysis showed a good fit for the environmentally responsible behavior study model. The results suggested that …

Reference Ranges For Corpus Callosum And Cavum Septi Pellucidi Biometry On Prenatal Ultrasound: Systematic Review And Meta-Analysis, Joshua I Rosenbloom, Lauren H Yaeger, Shay Porat

2020-Current year OA Pubs

We conducted a systematic review and meta-analysis of published nomograms for fetal corpus callosum and cavum septi pellucid biometry. A structured literature search was conducted to identify studies that reported normal measurements of the fetal corpus callosum and cavum septi pellucidi. Random effects metaanalysis was used to calculate normal ranges, and reference curves are provided. The quality assessment demonstrated that there was generally poor reporting regarding maternal characteristics and neonatal outcomes. Our findings emphasize that standardization of research protocols and publishing criteria for normal biometric ranges is needed.

Why New Zealand’S Indigenous Reconciliation Process Has Failed To Empower Māori Fishers: Distributional, Procedural, And Recognition-Based Injustices, Hekia Bodwitch, Andrew M. Song, Owen Temby, John Reid, Megan Bailey, Gordon M. Hickey

School of Earth, Environmental, & Marine Sciences Faculty Publications

How is it that the New Zealand government’s process for re-establishing Indigenous fishing rights has failed to deliver thriving Māori fisheries? This paper examines why, at Te Waihora, a coastal lake, and site of one of the nation’s longest running and best-funded state-Māori co-governance agreements, Māori fishers have been unable to use their rights to support their fishery. As of 2018, the lake’s culturally and ecologically significant eel population was no longer commercially viable, a decline fishers have attributed to rampant dairy industry expansion upstream. Drawing on environmental justice literatures, we deploy a multi-dimensional framework to identify factors shaping possibilities …

Student Publications

Purpose: The coronavirus disease 2019 (COVID-19) pandemic has shown unprecedented impact world-wide since the eruption in late 2019. Importantly, emerging reports suggest an increased risk of thromboembolism development in patients with COVID-19. Meanwhile, it is found that aspirin reduced mortality in critically ill patients with non-COVID-19 acute respiratory distress syndrome. Therefore, a meta-analysis was performed to investigate the effects of aspirin on COVID-19 mortality.

Methods: A systematic literature search was conducted in 10 electronic databases and 4 registries. Random effects models were used to calculate pooled relative risks (RRs) with 95% confidence intervals (Cis) to estimate the effect of aspirin …

Pyoderma Gangrenosum: An Updated Literature Review On Established And Emerging Pharmacological Treatments, Carlo Alberto Maronese, Matthew A. Pimentel, May M. Li, Giovanni Genovese, Alex G. Ortega-Loayza, Angelo Valerio Marzano

Student Publications

Pyoderma gangrenosum is a rare inflammatory skin disease classified within the group of neutrophilic dermatoses and clinically characterized by painful, rapidly evolving cutaneous ulcers with undermined, irregular, erythematous-violaceous edges. Pyoderma gangrenosum pathogenesis is complex and involves a profound dysregulation of components of both innate and adaptive immunity in genetically predisposed individuals, with the follicular unit increasingly recognized as the putative initial target. T helper 17/T helper 1-skewed inflammation and exaggerated inflammasome activation lead to a dysregulated neutrophil-dominant milieu with high levels of tumor necrosis factor-α, interleukin (IL)-1β, IL-1α, IL-8, IL-12, IL-15, IL-17, IL-23, and IL-36. Low-evidence studies and a lack …

Optimal Standards Of Proof In Antitrust, Murat C. Mungan, Joshua Wright

Faculty Scholarship

Economic analyses of antitrust institutions have thus far focused predominantly on optimal penalties and the design of substantive legal rules, and have largely ignored the standard of proof used in trials as a policy tool in shaping behavior. This neglected tool can play a unique role in the antitrust context, where a given firm may have the choice to engage in exceptional anticompetitive or procompetitive behavior, or simply follow more conventional business practices. The standard of proof used in determining the legality of a firm’s conduct affects not only whether the firm chooses to engage in pro- versus anticompetitive behavior, …

Inconceivable Families, Malinda L. Seymore

Faculty Scholarship

Basic biology tells us that each child has no more than two biological parents, one who supplies the egg and one who supplies the sperm. Adoption law in this country has generally followed biology, insisting only two parents be legally recognized for each child. Thus, every adoption begins with loss. Before a child can be adopted, that child must first be cut off from their family of birth, rendering the equation of adoption one of subtraction, not addition. This Article examines the biological model of adoption that insists on mimicking the nuclear family—erasing one set of parents and replacing them …

How Airline Managers Assess Their Competitive Positions: A Case Study In Turkey, Huseyin O. Aldemir, Ferhan K. Sengur

Journal of Global Business Insights

This study focused on how airline managers perceive their competitive positions. Based on the perceptions of the airline managers, strengths-weaknesses-opportunities-threats (SWOT) analyses were carried out. All scheduled and unscheduled passenger carriers in Turkey were used as sample for this research. The data were acquired through qualitative research by semi-structured interviews with senior executives of the airlines. This research demonstrated how airline managers assess their competitive positions in the market. The similarities and differences related to each airlines’ strengths, weaknesses, opportunities, and threats were put forward. Interviews among managers of the airline companies operating in Turkey revealed varied perceptions on business …

Knee Joint Biomechanics During Gait Improve From 3 To 6 Months After Anterior Cruciate Ligament Reconstruction, Kelsey Neal, Jack R. Williams, Abdulmajeed Alfayyadh, Jacob J. Capin, Ashutosh Khandha, Kurt Manal, Lynn Snyder-Mackler, Thomas S. Buchanan

Physical Therapy Faculty Research and Publications

Gait alterations after anterior cruciate ligament reconstruction (ACLR) are commonly reported and have been linked to posttraumatic osteoarthritis development. While knee gait alterations have been studied at several time points after ACLR, little is known about how these biomechanical variables change earlier than 6 months after surgery, nor is much known about how they differ over the entire stance phase of gait. The purpose of this study was to examine knee gait biomechanical variables over their entire movement pattern through stance at both 3 and 6 months after ACLR and to study the progression of interlimb asymmetry between the two …

Empirical Transmit Field Bias Correction Of T1w/T2w Myelin Maps, Matthew F. Glasser, Timothy S. Coalson, Michael P. Harms, Junqian Xu, Graham L. Baum, Joonas A. Autio, Edward J. Auerbach, Douglas N. Greve, Essa Yacoub, David C. Van Essen, Nicholas A. Bock, Takuya Hayashi

2020-Current year OA Pubs

T1-weighted divided by T2-weighted (T1w/T2w) myelin maps were initially developed for neuroanatomical analyses such as identifying cortical areas, but they are increasingly used in statistical comparisons across individuals and groups with other variables of interest. Existing T1w/T2w myelin maps contain radiofrequency transmit field (B1+) biases, which may be correlated with these variables of interest, leading to potentially spurious results. Here we propose two empirical methods for correcting these transmit field biases using either explicit measures of the transmit field or alternatively a 'pseudo-transmit' approach that is highly correlated with the transmit field at 3T. We find that the resulting corrected …

Holy Simplicity: The Physician's Role In End-Of-Life Conversations, Joseph L. Williams, Benjamin Doolittle

Student Publications

Early initiation of end-of-life (EOL) conversations has been shown to improve patient agency in dying, increase early access to hospice care, and facilitate a dignified death. Despite the benefits of early initiation, EOL conversations do not occur as readily as physicians or patients wish. While medicine is commonly considered both a science and an art, increasing medicalization may narrow a clinician's focus towards procedures or specialized clinical frameworks rather than a patient's end-of-life wishes. Since physicians are ambassadors of clinical knowledge and are trusted patient advocates, it is important they facilitate EOL conversations early in the dying process. Patients desire …

A Systematic Review Of Recent And Ongoing Clinical Trials In Patients With The Neurofibromatoses, Simge Acar, Edwin Nieblas-Bedolla, Amy E Armstrong, Angela C Hirbe

2020-Current year OA Pubs

INTRODUCTION: The neurofibromatoses comprise three different genetic conditions causing considerable morbidity and mortality: neurofibromatosis type 1 (NF1), neurofibromatosis type 2 (NF2), and schwannomatosis (SWN). This review summarizes recent and ongoing clinical trials involving patients with neurofibromatoses to better understand the current state of clinical trial research centered around these conditions and inform areas of need.

METHODS: A search was conducted using the Cochrane Central Register of Controlled Trials and clinicaltrials.gov databases. Inclusion and exclusion criteria were designed to identify clinical trials focused on patients with NF1, NF2, or SWN completed in or after 2010 and in process as of December …

Clinical Trial Data Of Anti-Pd-1/Pd-L1 Therapy For Recurrent Or Metastatic Nasopharyngeal Carcinoma: A Review, Douglas R Adkins, Robert I. Haddad

2020-Current year OA Pubs

IMPORTANCE: Anti-programmed cell death receptor-1 (PD-1) therapy is standard of care for incurable recurrent or metastatic non-nasopharyngeal head and neck cancer. In contrast, there are no regulatory agency-approved anti-PD-1 agents indicated for the treatment of recurrent or metastatic nasopharyngeal carcinomas (RM-NPC) in the Western hemisphere, and no standard treatment option exists beyond first-line chemotherapy for RM-NPC. The pace of development of novel systemic therapy regimens for RM-NPC has been slow compared to many other advanced tumor types, leaving an unmet clinical need for these patients with a poor prognosis.

OBSERVATIONS: Recent clinical trials have documented the clinical activity of anti-PD-1 …

2020-Current year OA Pubs

INTRODUCTION: To develop a patient-centred financial incentive delivery strategy to improve antiretroviral treatment adherence in adolescents and young adults (AYA) living with HIV in Kisumu, Kenya, we conducted a mixed methods study exploring preferences.

METHODS: A discrete choice experiment (DCE) and focus group discussion (FGD) were conducted simultaneously to identify preferences for five incentive delivery strategy features: value, eligibility, recipient, format and disbursement frequency. We used consecutive sampling to recruit AYA (14-24 years) living with HIV attending three health facilities in Kisumu, Kenya. We calculated mean preferences, willingness to trade, latent class membership and predictors of latent class membership. The …

Two-Phase Matheuristic For The Vehicle Routing Problem With Reverse Cross-Docking, Aldy Gunawan, Audrey Tedja Widjaja, Pieter Vansteenwegen, Vincent F. Yu

Research Collection School Of Computing and Information Systems

Cross-dockingis a useful concept used by many companies to control the product flow. It enables the transshipment process of products from suppliers to customers. This research thus extends the benefit of cross-docking with reverse logistics, since return process management has become an important field in various businesses. The vehicle routing problem in a distribution network is considered to be an integrated model, namely the vehicle routing problem with reverse cross-docking (VRP-RCD). This study develops a mathematical model to minimize the costs of moving products in a four-level supply chain network that involves suppliers, cross-dock, customers, and outlets. A matheuristic based …

Visualizing Politics In Indonesia: The Design And Distribution Of Election Posters, Colm A. Fox

Research Collection School of Social Sciences

Where studies have shown that visuals are the primary means of political communication, research continues to focus largely on text-based information. To add to our understanding of visual-political communications, this article analyses Indonesian election posters since the 1950s. Drawing on historical materials and on a content analysis of 4,000 election posters, it asks why election posters have been designed and distributed in particular ways. Findings indicate that in the past, posters used singular, though powerful, social symbols to mobilize demographic groups behind political parties. However, contemporary posters are more visually complex and more candidate-centered, making arguments as to what the …

In Covid-19 Health Messaging, Loss Framing Increases Anxiety With Little-To-No Concomitant Benefits: Experimental Evidence From 84 Countries, Charles A. Dorison, Et. Al., Andree Hartanto

Research Collection School of Social Sciences

The COVID-19 pandemic (and its aftermath) highlights a critical need to communicate health information effectively to the global public. Given that subtle differences in information framing can have meaningful effects on behavior, behavioral science research highlights a pressing question: Is it more effective to frame COVID-19 health messages in terms of potential losses (e.g., “If you do not practice these steps, you can endanger yourself and others”) or potential gains (e.g., “If you practice these steps, you can protect yourself and others”)? Collecting data in 48 languages from 15,929 participants in 84 countries, we experimentally tested the effects of message …

A Traitor-Resistant And Dynamic Anonymous Communication Service For Cloud-Based Vanets, Huiying Hou, Jianting Ning, Yunlei Zhao, Robert H. Deng

Research Collection School Of Computing and Information Systems

Cloud-based VANETs are designed to enable communication between high-speed vehicles. In such a highly dynamic environment, how to provide secure and anonymous communication service is a challenge. In this article, we affirmatively address the challenge by proposing a traitor-resistant and dynamic anonymous communication framework (TD-ACF) for cloud-based VANETs, which supports several advantageous features. In TD-ACF, each vehicle is represented by a set of attributes instead of its real identity, and the driving data is transmitted in encrypted form. Therefore, the anonymous authentication and the confidentiality of driving data are achieved in this way. Meanwhile, TD-ACF supports two practical requirements in …

Fine-Grained And Controllably Editable Data Sharing With Accountability In Cloud Storage, Huiying Hou, Jianting Ning, Yunlei Zhao, Robert H. Deng

Research Collection School Of Computing and Information Systems

With the increasing cloud storage service, users can enjoy non-interactive data sharing. Nonetheless, the data owner cannot timely update the shared data all the while. To ensure the timeliness and the authoritative source of the data, some users should be allowed to update the data on behalf of an authoritative data owner without changing data source. However, this allows harmful information to be injected into the data unnoticeably. How to efficiently realize editable cloud-based data sharing supporting malicious user tracing has not been fully explored. To address the problem, we propose a fine-grained and controllably editable cloud-based data sharing scheme …

Val: Volume And Access Pattern Leakage-Abuse Attack With Leaked Documents, Steven Lambregts, Huanhuan Chen, Jianting Ning, Kaitai Liang

Research Collection School Of Computing and Information Systems

Searchable Encryption schemes provide secure search over encrypted databases while allowing admitted information leakages. Generally, the leakages can be categorized into access and volume pattern. In most existing SE schemes, these leakages are caused by practical designs but are considered an acceptable price to achieve high search efficiency. Recent attacks have shown that such leakages could be easily exploited to retrieve the underlying keywords for search queries. Under the umbrella of attacking SE, we design a new Volume and Access Pattern Leakage-Abuse Attack (VAL-Attack) that improves the matching technique of LEAP (CCS ’21) and exploits both the access and volume …

Lived Religion In A Digital Age: Technology, Affect And The Pervasive Space-Times Of “New” Religious Praxis, Quan Gao, Orlando Woods, Lily Kong, Siew Ying Shee

Research Collection College of Integrative Studies

This paper explores how Christian practices of prayer are being reconfigured through digital media in Singapore. Although digital technologies are an area of burgeoning interest amongst social and cultural geographers, the ways in which these technologies reconfigure the space-times of religious praxis and engender new affective relations or subjectivities of religion have not yet been embraced. This paper fills the lacuna by bringing existing studies on religion, technology and affect into constructive conversation with each other. By elaborating on digital prayer as an affective assemblage of religious practice, we show how digital technologies blur institutional boundaries and create new affordances …

Desert Arcologies And Path Dependencies, Sayd Randle

Research Collection College of Integrative Studies

In Phoenix, Arizona last year, the local high temperature topped 100 degrees Fahrenheit on 145 days, a new record. Of those 145, 53 days saw top temperatures above 110 and 14 days exceeded 115 – also new peaks. Taken together, these numbers strongly suggest that to live out 2020 in Phoenix was to inhabit an environment sliding towards a painful, and perhaps even hellish, new baseline. Of course, numbers are known to occlude at least as much as they reveal. But in the case of Arizona’s largest metropolitan area, they’re useful for framing a certain conventional wisdom about the place: …

Infrared Thermography In The Built Environment: A Multi-Scale Review, Miguel Martin, Adrian Chong, Filip Biljecki, Clayton Miller

Research Collection College of Integrative Studies

The paper presents a review on major contributions in infrared thermography to study the built environment at multiple scales. To elaborate the review, hundreds of studies conducted between the 1980s and 2020s were first selected based on their relevance to the scope. Afterward, the most relevant contributions were classified and chronologically sorted. From the classification, it is observed that most reviewed studies were conducted to evaluate the thermal performance of buildings or detect their defects using images collected by an infrared camera. At the same time, a considerable number of studies used thermal images obtained by a satellite to observe …

Posterior-Based Wald-Type Statistic For Hypothesis Testing, Xiaobin Liu, Yong Li, Jun Yu, Tao Zeng

Research Collection School Of Economics

A new Wald-type statistic is proposed for hypothesis testing based on Bayesian posterior distributions under the correct model specification. The new statistic can be explained as a posterior version of the Wald statistic and has several nice properties. First, it is well-defined under improper prior distributions. Second, it avoids Jeffreys–Lindley–Bartlett’s paradox. Third, under the null hypothesis and repeated sampling, it follows a distribution asymptotically, offering an asymptotically pivotal test. Fourth, it only requires inverting the posterior covariance for parameters of interest. Fifth and perhaps most importantly, when a random sample from the posterior distribution (such as MCMC output) is available, …
