Evaluation And Revision Of The Practice Environment Scale Of The Nursing Work Index For Acute Care Hospital Staff Nurses, Caitlin M. Campbell

Dissertations

The Practice Environment Scale of the Nursing Work Index (PES-NWI) is the most frequently used instrument for measuring the nursing work environment. The original PES-NWI obtained its items directly from the parent instrument, the Nursing Work Index, which was developed in the 1980s. However, potential value change among younger generations and vast historical, social, and technological transformations in the way healthcare is provided may have led to different factors that compose a favorable work environment for nurses working today.

Online Clinical Post-Conference, Face-To-Face Clinical Post-Conference: Effects On Critical Thinking In Associate Degree Nursing Students, Kristie A. Berkstresser

Dissertations

Nurse educators, at every level of pre-licensure nursing education, are charged with developing critical thinking skills within their students.

Although police use of private cameras has become the subject of contentious debate, our understanding of private camera systems and how they are used by the police remains quite limited, largely focusing on either utopian or dystopian narratives. Drawing on interviews with community organizations in St. Louis, Missouri, that have installed neighborhood surveillance systems, this dissertation seeks to provide some insight into the rise …

Water Management And Corrosion Performance From Protective Polymer Coatings With Spatially Controlled Hydrophilic Domains, Jessica M. Davison

Dissertations

Metallic corrosion has become an annual multibillion-dollar problem for the industrialized world and global contamination issue through the process of repair, removing, and reapplying protective coatings. Typical corrosion resistant coatings are comprised of polymeric coating layers with anti-corrosive pigments, plasticizers, sacrificial additives, and/or other formulation materials, which are formulated to prevent, detect, and manage corrosion. Our counterintuitive approach was to improve upon the understanding of how, when, where, and why environmental contaminants (reactants, mainly water and electrolytes) driving corrosion, propagate and accumulate as localized hydrophilicity shifts within a model polymer coated substrate. Herein, hydrogel particles (HGP) were synthesized of defines …

Strategic Human Resource Management Practice Integration And Organizational Ambidexterity In Vuca Times, Gizzatta Cook

Dissertations

ABSTRACT

The failure rate of business strategy implementation hovers around 50% due to a lack of organizational ambidexterity in the realities associated with a four-dimensional paradigm referred to as a volatile, uncertain, complex, and ambiguous (VUCA) environment (Chattopadhyay et al., 2017). Anwar and Abdullah (2021) state that organizational success depends highly on how well organizational leaders manage and administer their human resource management practices. Today's successful organizations must adapt to societal changes to survive and thrive (Chattopadhyay et al., 2017).

Surviving and thriving beyond today’s organizational constraints also involves a business's ability to demonstrate organizational ambidexterity. Organizational ambidexterity is the …

Characterization Of Innate Immune Responses In Mouse Trophoblast Stem Cells And Their Differentiated Cells, Mona Fendereski

Dissertations

The blastocyst is the preimplantation stage embryo consisting of two major components: the inner cell mass (ICM) and the trophectoderm (TE). The ICM forms the fetus, whereas the TE contributes to the placenta development. Previous studies have demonstrated that human and mouse embryonic stem cells (ESCs) derived from the ICM are deficient in expressing type I IFNs in response to viral infection. This study investigated the innate immune responses in mouse trophoblast stem cells (TSCs) and their in vitro differentiated trophoblasts (TSC-TBs). I report that, unlike ESCs, TSCs have a functional IFN system. They can express and respond to type …

Anti-Human Trafficking Training For Law Enforcement: An Assessment Of Practice In A Southern State, Patricia Ann Southerland

Dissertations

Human trafficking, a crime hidden in plain sight, does not answer to civility or the inherent human rights established within societal norms. While several factors influence this heinous crime, the absence of training and the incorporation of best practices among law enforcement personnel impairs the proper identification of victims, as well as the arrest and prosecution of facilitators, traffickers, and buyers (Clawson, Dutch, & Cummings, 2006; Dandurand, 2017; Darwinkel, Powell, & Tidmarsh, 2013; Davy, 2016; Efrat, 2015; Farrell, 2014; Farrell, McDevitt, Fahy, 2010; Farrell, McDevitt, Pfeffer, Fahy, Owens, Dank, & Adams, 2012; Farrell & Pfeffer, 2014, Grubb & Bennet, 2012; …

A Framework For Assessing The 4th Rank Dispersivity Tensor Under Anisotropic Axial Symmetries, Xiang Fan

Dissertations

Multi-dimensional expansion of the advection-dispersion equation necessitated the representation of dispersivity as a 4th rank tensor. This tensorial form of dispersivity has 81 terms in three-dimensions with a maximum of 36 independent terms that may be used to describe Fickian spreading of a dissolved contaminant plume according to intrinsic properties of a porous medium. The complexity of the 4th rank tensor has led to the common practice of simplifying the tensor to only 2 or 3 independent terms by assuming isotropic conditions, although isotropic porous media are uncommon in nature as many natural geologic systems exhibit pronounced anisotropy. A broad …
