Acute-To-Home Care Nursing Handoffs: Distributed Cognition Across Patterns Of Knowledge, Rosemary Kennedy

Dissertations

Timely, explicit, and effective communication of patient information during care transitions is fundamental to safe care. Studies show that handoffs or transfers of patient care from one provider to another are susceptible to communication failures (Riesenberg et al., 2009a). Most studies on communication failures focus on communication between providers within the same setting of care. Few studies, if any, focus on communication between care settings in different locations. However, research has identified gaps in care during critical transitions and identified poor communication and incomplete transfer of information as the root cause (Naylor et al., 2004). This qualitative dissertation consists of …

Risk Perception, Psychological Well-Being, And Health-Promoting Behaviors In Persons Informed Of A Coronary Artery Calcium Score, Jennie Elizabeth Johnson

Objective: To examine how awareness of a CAC score affects risk perception and health-promoting behaviors in persons at high risk for CVD.

Methods: This study used a descriptive prospective design with 174 high risk adults (3 or more major risk factors) recruited at a radiology center offering CAC scans in a Chicago suburb. …

Neighborhood Attachment Among Latinos In Low-Income Communities, Kathleen Bachtell

Dissertations

Neighborhood attachment, defined as an individual's feelings about their social commitment to a particular community, has been a central focus of studies involving space and place (Smith 1975) and community activism (Guest and Lee 1983, Crenshaw and St. John 1989) in the U.S. Yet despite the advancement of this work and a growing body of qualitative research exploring the dynamic experiences of immigrants and their descendants in particular communities, it is not clear how being born in the U.S. versus Mexico or Latin America impacts the formation of neighborhood attachment among Latinos. This limits our understanding of urban renewal, as …

The Direct And Indirect Impact Of Pain Intensity, Weight Status, And Activity Involvement On Social Competence Outcomes In Children And Adolescents With Spina Bifida, Bonnie S. Essner

Dissertations

The purpose of this study was to test a mediated effects model in which youth with spina bifida who have greater pain, are more overweight, or have worse motor control were expected to have fewer friends and to display worse social performance in part because their higher degree of condition severity interferes with their involvement in developmentally-appropriate activities.

Data for the current study were drawn from the first wave of a larger, longitudinal study of psychosocial adjustment of children and adolescents with spina bifida. The sample was comprised of 108 children and adolescents with spina bifida and shunted hydrocephalus, ages …

Descriptions Of Childhood Trauma, Effects Of The Trauma, And How Adults Moved Through The Trauma To Normalized Behavior, Alice Katherine Schaaf

Dissertations

Problem. People who are not able to overcome the effects of childhood trauma often waste their human potential on substance abuse and illegal and illicit lifestyles; they end up in prison, uneducated, or develop self-destructive behavior. They often struggle with poor learning and social skills and are not able to be successful in life. However, some individuals do succeed. This study interviewed eight individuals who suffered childhood trauma and developed ways of overcoming that trauma to live prosperous, productive, and, in many regards, full lives.

Method. This qualitative study used interviews to explore how adults traumatized as children described childhood …

Role Of Pseudomonas Produced Hydrogen Cyanide In Biological Control Of Plant-Parasitic Nematodes, Haytham Aly

Dissertations

Plant-parasitic nematodes are among the most devastating pests world-wide, causing extensive damage to important agriculture crops. The management of nematodes is challenging. Current methods used for nematode control rely mostly on using chemical nematicides and naturally resistant plants. Because of serious health and environmental problems associated with chemical control and over use of resistant plants resulting in resistant breaking strains of nematodes, alternative nematode-control methods are needed. Several potential nematode-biocontrol agents, including bacteria and fungi, have been studied for their antagonistic effect toward plant-parasitic nematodes. However, a concise picture about the biological agent’s mechanisms used to antagonize nematodes remains elusive. …

Effects Of The Exotic Shrub Lonicera Maackii On The Plant Animal Interactions In The Invaded Habitat, Humberto De Paula Dutra

Dissertations

Invasive plants are an economical, political, social, and ecological problem. Some invasive species are a serious concern for society because some of them are diseases, some are agricultural pests, and some become major threats to the ecosystems. Most studies with invasive species are limited because they measure only the impact of the invasion via direct pathways. Unfortunately, the potential for non-native plant species to alter ecosystem functions via indirect pathways mediated by interactions with animals just recently became broadly recognized. This research investigates the interactions of Amur honeysuckle with native fauna and how these interactions indirectly affect other trophic levels …

This research examined how medical laboratory science clinical instructors learn to conduct clinical instruction. In order to describe the phenomenon of clinical instructors learning to conduct clinical instruction, a mixed methods approach was used. In the …

An Analysis Of Burmese And Iraqi Resettlement Location And Assimilation In A Midsized City: Implications For Educational And Other Community Leaders, Donna Schiess Renaud

Dissertations

Refugees face different circumstances than other immigrants regarding housing in initial resettlement in the U.S. Refugees have no choice of their initial residence as this is determined in advance by the resettlement agency. Refugees who belong to minority ethnic groups and who have little education or skills may experience discrimination and hostility from local citizens. Resettlement areas that are high in population density, rental units, minorities, crime, unemployment, inadequate transportation, and low income may present additional barriers to cultural and economic assimilation.

This mixed-method study had a twofold purpose. The first was to describe quantitatively how the initial resettlement address …

The Impact Of Dynamic And Passive Standing On Bone Mineral Density And Appositional Growth In Immobilized Children, Megan Diane Damcott

Dissertations

The first discovery of the potential role that mechanical loading has on determining the strength of bone occurred in 1892. However, for almost a century after this discovery, the specific mechanisms influenced by mechanical loading remained locked in a mysterious 'black box'. Then in the 1960s, the 'black box' was opened and continued work has now unlocked the basic mechanisms involved in mechanical loading and whole-bone strength. This increased knowledge has spurred clinicians and researchers to investigate the impact of weight-bearing interventions on individuals with an increased risk of osteoporosis. The most common weight-bearing clinical intervention used in non-ambulant populations …

Identification And Analysis Of Proteins And Genes Responsible For Microbial Anaerobic Nitrate-Dependent Iron Oxidation And Overexpression In E. Coli Of Perchlorate Reductase, Ming Gao

Dissertations

SECTION 1 Iron is the fourth most abundant element on the earth crust as well as an essential nutrient for all living organisms. The cycling of iron between the environment and biological systems and the microbial-mediated transformation between Fe2+ and Fe3+ has a significant impact on the biogeochemistry of the environment. The recently discovered microbially-mediated anaerobic nitrate-dependent oxidation of Fe2+ has been shown to play an important role in global iron biogeochemical cycling. Furthermore, the formation of iron oxide from anaerobic nitrate-dependent Fe2+ oxidation results in the adsorption and precipitation of soluble toxic heavy metals and radionuclides from surrounding environment. …
