Nurses -- Health and hygiene. Employee health promotion.
Background. Worksite health promotion programs (HPP) support employees' health behaviors to prevent downstream diseases. Maximizing participation can optimize program impact. Objectives. To assess staff nurses' participation in three HPP - flu...
Clinical medicine -- Practice. ; Medicine -- Practice. ; Group medical practice.
Health care micro-systems are small, organized groups of clinicians and staff working together with a shared clinical purpose to provide care for a defined set of patients. The size of individual micro-systems vary--a micro-system must be large...
Notables A-B; Han081201-08/12/88; Hanover, N.H.: Bruce Babbitt (right), former Governor (D) of Arizona, spoke at Dartmouth College on 8/11, on what it was like to have been an unsuccessful candidate for President in 1988. Seen talking to N.H....
NIMA-related kinases (Neks) control several aspects of cell division downstream of master mitotic regulators such as Cdk1 and Plk1. Though depletion of Nek6, Nek7, or Nek9 results in cytokinesis failure, to date no molecular mechanism has been...
This thesis contains material relating to two separate subjects. The first section determines when the C*-algebra affiliated to a directed graph has continuous trace. We use groupoid methods and the focus is on producing conditions on a graph that...
Partially ordered sets. ; Convex polytopes. ; Representations of groups.
This thesis deals with geometric representations of ordered sets. In a geometric representation, each element of the ordered set is assigned a geometric object, with two elements incomparable in the ordered set if and only if the corresponding...
The study of twin primes gives rise to several famously difficult problems in number theory--in fact, we still cannot definitively say whether there are infinitely many twin primes. In this work, we consider a related problem, namely: What is the...
Violent video games are immensely popular among children and adults, making it crucial to understand how these games affect the thoughts, feelings, and behaviors of those who play them. The present research proposed an account by which video game...
There are no Vassiliev invariants of degree one for classical knots. A. Henrich proved the existence of a sequence of three Vassiliev invariants of degree one for virtual knots. The invariants get stronger and stronger, and the final invariant is...
We study motion planning problems, finding trajectories that connect two configurations of a system, from two different perspectives: optimality and survivability. For the problem of finding optimal trajectories, we provide a model in which the...
Many protocols for adoptive T cell therapy (ACT) include preparative conditioning strategies to deplete host lymphocytes prior to T cell infusion. Total body irradiation and high-dose chemotherapy regimens not only relieve immunosuppression, but...
Objectives: This dissertation comprises three essays on geographic variations in healthcare, and the association between utilization and health outcomes. I first explore associations between outpatient visits and Medicare beneficiaries'...
Access control is a core component of any information-security strategy. Researchers have spent tremendous energy over the past forty years defining abstract access-control models and proving various properties about them. However, surprisingly...
This thesis constitutes the first steps in the author's program to investigate the question of when a homotopy of 2-cocycles Ï‰ = {Ï‰[subscript t]}[subscript tâˆŠ[0,1]] on a locally compact Hausdorff groupoid Æ“ induces an isomorphism of the...
Robots -- Control systems -- Design and construction. Mobile robots. Robots -- Dynamics.
This thesis examines the issues of vehicle and information dynamics in the control of a multi-robot system using a radial-basis potential function controller. Distributed control of multi-robot systems requires each robot to communicate state...
Overweight persons -- Attitudes. ; People with disabilities -- Attitudes. ; Obesity -- Public opinion. ; Stigma (Social psychology). ; Self-presentation.
In the last few years, a new perspective on the management of obesity has emerged. Instead of focusing on dieting and weight loss efforts, the new approach focuses on size acceptance. The concept of positively accepting one's deviant features has...
The advent of hypervisors revolutionized the computing industry in terms of malware prevention and detection, secure virtual machine managers, and cloud resilience. However, this has resulted in a disjointed response to handling known threats...
Since their discovery in laboratory plasmas in the 1920s, Langmuir waves have been observed to be ubiquitous in plasma environments, particularly in space plasmas. From the greater solar wind to planetary foreshocks and the auroral ionosphere,...
In this thesis we develop a theory of Fourier analysis and fast Fourier transforms (FFTs) for finite inverse semigroups. Our results generalize results in the theory of Fourier analysis for finite groups. There is a general method for generating...
We start by introducing avoidance coupling of Markov chains, with an overview of existing results. We then introduce and motivate a new notion, uniform coupling. We show that the only Markovian avoidance coupling on a cycle is of this type, and...
Electronic data processing -- Distributed processing. ; Computer network architectures. ; Programming languages (Electronic computers) -- Semantics. ; Database management.
I tackle the problem of naming and sharing resources across administrative boundaries. Conventional systems manifest the hierarchy of typical administrative structure in the structure of their own mechanism. While natural for communication that...
A mobile agent is an autonomous program that can migrate under its own control from machine to machine in a heterogeneous network. In other words, the program can suspend its execution at an arbitrary point, transport itself to another machine, and...
We begin with a presentation of the current state of Poljak and Turzik's conjecture that a matroid is sticky if and only if it is modular as described in [5] and [1]. We show that all graphic, cographic, and regular matroids must satisfy the...
In the late 1960s, Ihara began work that led to the Ihara zeta function, a zeta function which is defined on a finite graph. This function is an interesting graph invariant which gives information on expansion properties of the graph. It also...
