The purpose of this quantitative study was to evaluate how personal constructs of trust may affect outcomes at the organizational level among workers and managers in hierarchal structured organizations. The topics of the research questions addressed the extent which cultural values and the relative trust situation affected individuals' perceptions of …

Clinician Perspectives Of Adult High-Functioning Autism Support Groups' Use Of Neurodiversity Concept, Gwendolyn Spencer Barnhart

Walden Dissertations and Doctoral Studies

Ample research has examined the impact of autism for children and families, but less has addressed the effects of this condition for adults. The literature indicates that adults on the autism spectrum suffer from depression and have a heightened risk of suicidal ideation because of their social skills deficits. Research also shows that individuals with high-functioning autism (HFA) can benefit from participating in support groups. In addition, research indicates that use of the term "neurodiversity" rather than other diagnostic labels encourages increased self-esteem to persons on the autism spectrum. This grounded theory study sought to understand the belief of clinicians …

Optimizing Rna Extraction From Fungal-Algal Tissues For Transcriptomic Gene Expression Analysis, Michael J. Hohl

Honors Theses

Extracting high-quality RNA is critical for downstream applications such a qRT-PCR and RNA-Seq based transcriptomics. Single-stranded RNA is readily susceptible to degradation by environmental RNases, necessitating rapid and sterile homogenization techniques; freezing at -80°C, lysis buffer addition, and short bursts of beadbeating have been shown to increase yields and quality of extracted RNA. Utilizing fungal-algal tissues from the model symbiosis between the filamentous fungi Aspergillus nidulans and the green alga Chlamydomonas reinhardtii, three different commercial homogenizers and six RNA extractions kits were assessed and an optimized extraction protocol for total RNA from fungal-algal tissues was determined. Using the protocol designed …

Patient Experiences With Small-Scale Pharmacy Compounding, Morgan Cawthon

Honors Theses

Investigators examined patients' use, knowledge and perceptions of pharmacy compounding at an independent compounding pharmacy in Mandeville, Louisiana. Data were collected using a self-administered survey that patients could complete in hard-copy in the pharmacy or at home, or online using Qualtrics. Investigators found that, in some instances, patients who use compounded medications, or have a member of their household who uses compounded medications, may be more knowledgeable or have more positive perceptions of compounded medications. However, patients who did not have experience with compounds were not unknowledgeable about the practice and did not report any negative perceptions of compounding. These …

Risk Factors And Outcomes For Bloodstream Infections Among Patients With Skin Infections, Michael Rybak Rybak

Walden Dissertations and Doctoral Studies

Acute bacterial skin and skin structure infections (ABSSSI) are common infections within the local community, and they result in higher morbidity and health care costs.

In this case control investigation, 392 patients consisting of 196 cases (ABSSSI + BSI) and 196 controls (ABSSSI) were investigated to determine risk for BSI. Both sociodemographic and underlying conditions were evaluated. According to bivariate analysis of cases and …

Reviving Family Worship In The Rocky Mountain Indonesian Seventh-Day Adventist Church, Purasa Marpaung

Doctor of Ministry Projects

Problem

Seventh-day Adventist immigrants struggle to maintain Indonesian Adventist family worship practices in the process of assimilating to the United States culture. In particular, the family worship practices of the Rocky Mountain Indonesian Seventh-day Adventist Church have been adapted to fit the American environment and lifestyle. The practical family worship activities that were an essential component of the culture and identity of the people of Indonesian heritage are disappearing through exposure to new ideas and methods of worship. This lack of family worship in immigrant families must be addressed through cultural as well as theological perspectives.

Method

Couples, with at …

Developing The Educating For Discipleship Model To Be Used In Sabbath School In South Korea, Sun Il Kim

Doctor of Ministry Projects

Problem

Sabbath School is designed to be a system in which people are engaged in the process of becoming disciples, however, the church tends to operate in a formal and mechanical manner. As a result, the Sabbath School cannot be an agency to produce Christ’s disciples and the church cannot be a community of discipleship. Both of these conditions can be addressed by attending to the health of the faith community which allows the process of discipleship to accomplish transformation of the members of the community. The Seventh-day Adventist Church has Sabbath School, which is a great system for the …

Using Illustrations And Storytelling Via Incarnational Ministry To Reach Post-Christian Young Adults, David J. Resendes

They ranged in age from 16 to 34 and were of various races and some of mixed race. All were born and raised in the United States and spoke English. Of these subjects only two were from the church I pastor. One …

Hormonal And Social Factors Influencing Alternative Mating Tactic Decisions In Male Green Treefrogs, Hyla Cinerea, Brooks Pratt

Honors Theses

In many anuran species (frogs and toads), males alternate between calling and a non-calling satellite mating tactic. Satellite males characteristically associate with calling males and attempt to intercept females that are attracted to the vocalizations of the calling host male. The prevailing hypothesis is that the decision to adopt a calling or satellite mating tactic is based on relative attractiveness — males are predicted to adopt a satellite mating tactic when the vocalizations of nearby males are more attractive than their own. In support of this hypothesis, previous studies have shown that satellite males can be induced to call by …

The Tgf-Β Pathway Mediates Doxorubicin Effects On Cardiac Endothelial Cells, Zuyue Sun, Jill Schriewer, Mingxin Tang, Jerry Marlin, Frederick Taylor, Ralph V. Shohet, Eugene A. Konorev

Faculty and Staff Publications

Elevated ALK4/5 ligands including TGF-β and activins have been linked to cardiovascular remodeling and heart failure. Doxorubicin (Dox) is commonly used as a model of cardiomyopathy, a condition that often precedes cardiovascular remodeling and heart failure. In 7-8-week-old C57Bl/6 male mice treated with Dox we found decreased capillary density, increased levels of ALK4/5 ligand and Smad2/3 transcripts, and increased expression of Smad2/3 transcriptional targets. Human cardiac microvascular endothelial cells (HCMVEC) treated with Dox also showed increased levels of ALK4/5 ligands, Smad2/3 transcriptional targets, a decrease in proliferation and suppression of vascular network formation in a HCMVEC and human cardiac fibroblasts …

Transitioning The Waldorf Seventh-Day Adventist Church To An Integrated Multiethnic/Multicultural Ministry, Kleyton Feitosa

Doctor of Ministry Projects

Problem

Charles County, Maryland, is an ethnically and culturally diverse community.
