Subgrouping Ulcerative Colitis Patients using Administrative Claims Data
Approximately 3 million patients in the US have been diagnosed with Ulcerative Colitis, a chronic inflammatory disease affecting the colon. Uncovering patient subgroups could improve treatment guidelines and help physicians choose an appropriate treatment plan for a patient. Here, we outline a …

A quantitative model in dialect subgrouping: The case of modern Wu dialects
… measurements, and under this new model, the subgrouping of the Modern Wu dialects, one of the major groups of Chinese dialects, is carried out, based on the syllable initials.

How Diversity Affects Teams
… social categorization can trigger dysfunctional subgrouping, potentially hindering the effective elaboration of diverse perspectives. Therefore, team diversity management plays a central role in enabling teams to leverage their diversity. Across four papers, this dissertation examines whether and …

Evidence from innovation: Reconstructing disharmonic headedness for Proto-Indo-European
… assumed that the innovations useful for subgrouping "may be phonological, morphological, or lexical". This project and others like it can help show the value of syntactic isoglosses for subgrouping purposes as well, and can even take the original idea a step further, showing that in some …

Heterogeneity modeling and longitudinal clustering
… strategy. Specifically, we propose a pairwise subgrouping approach to identify and categorize similar marketing effects into subgroups. We model customers' purchase decisions as binary responses under the generalized linear model framework and incorporate their longitudinal correlation. We …

Parallel hardware accelerated switch level fault simulation
… uses reverse level ordering, grouping, and subgrouping in order to partition transistors for parallel processing. This paper also presents an algorithm and complexity measure for parallel fault simulation as extended to the switch level. For the algorithm, the switch level fault simulation …

Multiuser Diversity Management for Multicast/Broadcast Services in 5G and Beyond Networks
… techniques conventional multicast scheme (CMS), subgrouping based on OMA (S-OMA), and subgrouping based on NOMA (S-NOMA). We provide conditions for their adequate selection regarding the specific network conditions (Chapter 4). Consequently, we propose heuristic methods for the dynamic multicast …

GLR Control Charts for Monitoring a Proportion
… we assume samples are collected using rational subgrouping with sample size n>1, and the binomial GLR statistic is constructed based on a moving window of past sample statistics that follow a binomial distribution. Steady state performance is evaluated for the binomial GLR chart and the other …

Patterns of Affiliation and Co -Operation in Howler Monkeys: An Alternative Model to Explain Social Organization in Non -Human Primates
… patterns. I conducted a detailed field study of subgrouping patterns, social affiliation, and ecology in two neighboring groups of black and gold howler monkeys ( Alouatta caraya) in Northern Argentina from April 2003 to December 2004. The study took place on Isla Brasilera, 290 ha, 27° 20'S …

Can Police Officers be Taught to be Fair? Lessons from a Randomised Controlled Field Trial on Training in Legitimacy for UK Counterterrorism Police Officers
… officers, on multiple outcomes. However, when subgrouping the effects based on different parameters, we show varying and at times non-significant effects , particularly with classroom- based training approaches and mixed components- based style of training on frontline police officers and …

Development of advanced methods for large-scale transcriptomic profiling and application to screening of metabolism disrupting compounds
… a computational tool for unsupervised molecular subgrouping of bulk and single-cell gene expression data, and for the comprehensive in-silico annotation of the discovered subgroups.

Mechanisms and Targeting of Neurodevelopmental Regulator Rest In Medulloblastoma Dissemination
<p>Molecular subgrouping of medulloblastoma (MB) has produced four subgroups: wingless (WNT), sonic hedgehog (SHH), group 3, and group 4. While patients with WNT tumors have the best prognosis, patients with SHH tumors have a more variable prognosis concurrent with metastatic disease. This subset …

An investigation into deviant morphology : issues in the implementation of a deep grammar for Indonesian
… voice marking that is characteristic of the subgrouping of its language family. In order to be able to characterise verbal behaviour in Indonesian, we first need to devise a detailed analysis of voice for implementation. Another challenge we face is the claim that all open class words in …

Individualized learning and integration for multi-modality data
… part of the thesis, we develop a model-based subgrouping method for longitudinal data. Specifically, we propose an unbiased estimating equation approach for a two-component mixture model with correlated response data. In contrast to most existing longitudinal data clustering methods, the …

Challenges and opportunities in neuroimaging and population modelling of autism and ADHD
… but in late adolescence for ADHD. Multiple subgrouping approaches were used, including one which identified subgroups based on developmental trajectories. The number of subgroups identified varied by approach from 2-4, with some significant clinical differences between groups observed. …
