The Provision Of Mental Health Services By Rural Health Clinics, John A. Gale Ms, Stephanie Loux Ms, Barbara Shaw Jd, David Hartley Phd, Mha

Behavioral Health

The number of Rural Health Clinics (RHCs) providing specialty mental health services remains limited. This study examined changes in the delivery of mental health services by RHCs, their operational characteristics, barriers to the development of services, and policy options to encourage more RHCs to deliver mental health services. Key Findings: Approximately 6% of independent and 2% of provider-based RHCs offer mental health services by doctoral-level psychologists and/or clinical social workers. Models used to provide mental health services include contracted and/or employed clinicians housed in the same facility as primary care providers. A key element in the development of ...


Measures Of Executive Function In Children With Cochlear Implants, Lea Ashley Greiner 2010 University of Iowa

Measures Of Executive Function In Children With Cochlear Implants, Lea Ashley Greiner

Theses and Dissertations

This study aimed to answer whether current research addressing executive function abilities in cochlear implant users was accurately depicting their impairments. Secondly, this study aimed to identify differences in identification of executive function impairments when measured using parent report versus behavioral measures of executive function. Results suggest that children do have executive function impairments in areas of measure nonverbal planning, problem-solving, monitoring, and self-regulation abilities as well as attention to a visually presented array of pictures which has been documented in previous research. However, it is likely that these abilities are modulated by children with cochlear implants' poorer language ability ...


The Role Of Lexical Frequency, Telicity & Phonological Factors On Past Tense Production In Children With Sli & Their Typically Developing Peers, Melanie Elise Green 2010 University of Iowa

The Role Of Lexical Frequency, Telicity & Phonological Factors On Past Tense Production In Children With Sli & Their Typically Developing Peers, Melanie Elise Green

Theses and Dissertations

Limited research is available about how lexical and phonological verb properties interact with past tense production by children. Frequency of the inflected form and phonotactic probability might serve as input-driven alternatives to previously-studied factors such as lexical aspect and coda composition.

Archival elicited production data from 4-9 year old children with typical language (N = 24) and specific language impairment (N=14) using 108 two-clause complex sentences/85 different verbs were analyzed for past tense use, coda composition, telicity, phonotactic probability (Vitevitch & Luce, 2004), and lexical frequency (CHILDES; MacWhinney, 2000).

Several regression models were considered, including one with only categorical factors (e.g. obstruent/continuant ending), one ...


Passive Eruption Patterns In Central Incisors, Russell John Guymon 2010 University of Iowa

Passive Eruption Patterns In Central Incisors, Russell John Guymon

Theses and Dissertations

OBJECTIVE: The purpose of this study is to determine the eruption patterns of maxillary and mandibular central incisors from the first occlusal contacts to adulthood while comparing the differences in male and female eruption patterns. Previous studies have failed to obtain measurements into adulthood. We hope by using a final measurement during a subjects' adulthood we can better estimate final eruption times and measurements.

METHODS: The material for this research project was obtained from the Meredith Facial Growth Study from the University of Iowa Orthodontics Department. Records from a set of 64 subjects (35 males and 29 females) were used ...


Modulatory Activities Of Glycosaminoglycans And Other Polyanionic Polysaccharides On Cationic Antimicrobial Peptides, Beth Ellen Miskimins Mills 2010 University of Iowa

Modulatory Activities Of Glycosaminoglycans And Other Polyanionic Polysaccharides On Cationic Antimicrobial Peptides, Beth Ellen Miskimins Mills

Theses and Dissertations

Cationic antimicrobial peptides (CAPs) are an important component of the innate immune system and are instrumental in the elimination of bacteria, viruses, protozoa, yeast, fungi and cancerous cells from the body. CAPs are comprised of less than 100 amino acids and have a net positive charge due to a multitude of basic residues in their primary sequences. CAPs exert their antimicrobial activity primarily through the formation of pores in microbial membranes, but also play important immunostimulatory roles in the body. Glycosaminoglycans (GAGs) are negatively charged, polydisperse linear polysaccharides found at cellular surfaces. Although many protein-binding interactions of the GAG family ...


The Relationship Between Parental Language Input And Language Outcomes In Children With Cochlear Implants, Melinda Jean Grieb 2010 University of Iowa

The Relationship Between Parental Language Input And Language Outcomes In Children With Cochlear Implants, Melinda Jean Grieb

Theses and Dissertations

This study used the LENA Digital Language Processor to look at parental input as a possible factor affecting language performance variability in children with cochlear implants. Eight children between the ages of 2 and 6 with cochlear implants wore the LENA DLP for one full day while engaging in typical family activities. Adult word counts, child word counts, and number of conversational turns were compared to the child's Preschool Language Scales 3rd Edition scores and to LENA data from normal hearing children. It was found that parents of children with cochlear implants talk in a similar fashion to parents ...


Candida Species Variability As Seen Through Clinical Covariates And Drug Susceptibility Testing, Jesse Lee Hollanbaugh 2010 University of Iowa

Candida Species Variability As Seen Through Clinical Covariates And Drug Susceptibility Testing, Jesse Lee Hollanbaugh

Theses and Dissertations

With the recent emergence of candidemia as a significant cause of mortality in our health care system, clinicians must identify methods to minimize the sequelae of infection of this type in patients already burdened with serious underlying conditions. While well established as a major cause of blood stream infection (BSI), candidemia has been shown to have some of the highest rates of inappropriate therapy when compared to infections from all other sources. Rates of inappropriate therapy may be even higher for some of the less common and antifungal resistant non-albicans candidemia. Identifying those patients at risk for the development of ...

Physical Activity, Cardiorespiratory Fitness, Adiposity, And Cardiovascular Health In Children And Adolescents, Soyang Kwon

Theses and Dissertations

The goal of this dissertation research was to better understand relationships among physical activity (PA), cardiorespiratory fitness, adiposity, and cardiovascular (CV) health in children and adolescents. The aim of the first paper was to examine whether fitness and adiposity are independently associated with CV risk factors during puberty. Study participants were 126 prepubertal Caucasian children participating in a longitudinal four-year follow-up study. Fitness level was determined by VO2 max (L/min) obtained from maximal graded exercise testing and adiposity level was determined by the sum of skinfolds. Gender-specific individual growth curve models, including both VO2 max and the ...


Methicillin-Resistant Staphylococcus Aureus In Pork Production Facilities: Occupational Exposures And Infections, Kerry Reah Leedom Larson 2010 University of Iowa

Methicillin-Resistant Staphylococcus Aureus In Pork Production Facilities: Occupational Exposures And Infections, Kerry Reah Leedom Larson

Theses and Dissertations

This research focuses on occupational exposures associated with Methicillin-resistant Staphylococcus aureus (MRSA) in modern pork production facilities. This dissertation is composed of three related parts.

In Chapter II, "Methicillin-resistant Staphylococcus aureus in pork production shower facilities" we documented the presence of MRSA in shower facilities of conventional swine production systems where pigs were colonized with MRSA. We tested farms involved in different production phases (sow, nursery, and finisher) and geographical locations. In the two swine production systems studied, 3% and 26% of shower samples were positive for MRSA. Overall, the prevalence in showers was 19%.

In Chapter III, "Methicillin-resistant Staphylococcus ...

Materials and Methods: Forty-eight cadaver maxillary and mandibular jaw quadrants were obtained Two titanium mini-screws were placed in each jaw quadrant and maximum insertion torque was measured. Each mini-screw was subjected to tangential force application oriented perpendicular to placement of the mini-screw and parallel to the occlusal plane. The force applied at each deflection was measured up to 1.5mm, but only the first 0.60mm of movement was investigated ...


"We Will Always Be In The Shadows" - A Qualitative Descriptive Study Of Undocumented Latino Immigrants Surviving In The United States, Elizabeth C. Mendez-Shannon 2010 University of Iowa

"We Will Always Be In The Shadows" - A Qualitative Descriptive Study Of Undocumented Latino Immigrants Surviving In The United States, Elizabeth C. Mendez-Shannon

Theses and Dissertations

Research studies have pointed to specific challenges for undocumented Latino immigrants including exploitation in the workplace (Stoddard, 1976), denial of health care (Angel, Frias & Hill, 2005; Passel, 2005) and lack of access to higher education (Seif, 2004). In addition, fear is never far from their consciousness. Fear of being identified as illegal and faced with possible arrest and deportation are realities for undocumented Latino immigrants. Both work and home are unsafe, particularly because of immigration raids by federal agents. In addition they are stigmatized by mainstream society (Padilla & Perez, 2003). Even the word "undocumented" has been used interchangeably with words like "illegal" and "alien" suggesting criminal behavior. These hardships make it difficult for these immigrants to become part of mainstream society and create barriers to opportunities.

All of these factors should logically discourage Latin Americans from immigrating to the United States. However, both the documented and undocumented Latino populations in the United States continue to increase. Although the situation of new Latino immigrants, especially those who are undocumented, seems extremely difficult, there is something unexplained occurring that has not been accounted for in current research that allows them to survive these hardships. In addition, there is a gap in information about the immigration process gathered from immigrants themselves. Therefore, this study uses a qualitative descriptive approach to learn from undocumented immigrants about their experiences when they first came to the United States and how they negotiate their situation while living in the United States.

The major findings of this study offer an inside look into the world of undocumented Latino immigrants. The obstacles these immigrants face were language barriers, limited education and unfair wages at work. On the other hand, they also identify facilitators that were helpful during their initial transition into the U.S such as getting help in finding a job, knowing someone in the United States before immigrating, being connected to support networks, and receiving support from others who shared their struggles. However, these findings do not reflect the whole story.

Even though most of these Latino immigrants underwent stress and adversity as new undocumented immigrants, the study shows how they transformed their suffering using their personal strengths and drawing on support from a close-knit community. At the same time they maintained their cultural identity both in their immigrant community and within the larger community where they resided. An additional factor which contributed to their survival was that this particular community is unique in preserving the different cultures of ethnic groups rather than fusing them into a "melting pot."

Recommendations for practice include using a strengths perspective with clients and community; recommendations for teaching include using interdisciplinary educational strategies and involving students in experiential learning ...

Aspectual Tenses In Native Spanish-Speaking Adults, Theresa Rachel Prisco 2010 University of Iowa

Aspectual Tenses In Native Spanish-Speaking Adults, Theresa Rachel Prisco

Theses and Dissertations

Fourteen native Spanish-speaking adults participated in a study on tense and aspect in Spanish. Subjects viewed videos that depicted completed events or videos that ended with an ongoing event and chose a sentence in the past tense that best described the event. One condition included adverbial cues and the other condition did not. Subjects also read paragraphs describing bounded and unbounded events and chose a past tense verb that best fit the context. It was found that subjects consistently chose preterit responses for completed event videos in both the adverb and non-adverb condition, but responses varied more in the videos ...


Neuromuscular Adaptations During Perturbations In Individuals With And Without Bilateral Vestibular Loss, Nora Havlik Riley 2010 University of Iowa

Neuromuscular Adaptations During Perturbations In Individuals With And Without Bilateral Vestibular Loss, Nora Havlik Riley

Theses and Dissertations

Approximately 20% of the general population is affected by a vestibular disorder. Vestibular dysfunction is recognized as an important intrinsic factor leading to falls. Despite research on balance strategies with platform perturbations, limited information exists on neuromuscular performance of the knee with perturbations during functional tasks. Improved understanding of the effects of BVL on neuromuscular control of the knee will aid researchers and clinicians in developing rehabilitation programs that address the adaptations and balance deficits that occur with vestibular loss. Hence, the main purpose was to examine accuracy of performance, knee muscle activation patterns and long latency responses in response ...


Influence Of Working Memory And Audibility On Word Learning In Children With Hearing Loss, Derek Jason Stiles 2010 University of Iowa

Influence Of Working Memory And Audibility On Word Learning In Children With Hearing Loss, Derek Jason Stiles

Theses and Dissertations

As a group, children with hearing loss show slower language development than their peers with normal hearing. Age of intervention has a profound impact on language outcomes but data examining the correlation between degree of hearing loss and language outcomes are variable. Two approaches are used in the current study to examine this variability. In the first approach, we look at aided speech audibility as a potentially better predictor of communication outcomes than pure tone average. In the second approach, we look at a previously unexplored system in this population: working memory.

We enrolled 16 children with mild to moderately-severe ...


Word Learning Processes In Children With Cochlear Implants, Elizabeth Ann Walker 2010 University of Iowa

Word Learning Processes In Children With Cochlear Implants, Elizabeth Ann Walker

Theses and Dissertations

Children with cochlear implants (CIs) typically have smaller lexicons in relation to their same-age hearing peers. There is also evidence that children with CIs show slower rates of vocabulary growth compared to hearing children. To understand why children with CIs have smaller vocabularies, we proposed to investigate their word learning process and determine how it compares to children with normal hearing. The present study explores multiple aspects of word learning - acquisition, extension, and retention - to better inform us about the real-world process of lexical acquisition in children with CIs.

We evaluated 24 children with cochlear implants, 24 children with normal ...


Differential Growth Of The Frontonasal Suture In Rabbits, Maura Josephine Vroman 2010 University of Iowa

Differential Growth Of The Frontonasal Suture In Rabbits, Maura Josephine Vroman

Theses and Dissertations

The purpose of this study was to substantiate previous claims that differential growth across the frontonasal suture occurs and if this differential growth pattern is caused by an increased mitotic rate of the nasal bone.

Two six week old New Zealand White Rabbits were given calcein 20mg/kg IA, demeclocycline 20mg/kg IA, and BrdU 40mg/kg IA on Days 1, 11, and 14, respectively. The animals were euthanized using Ketamine 31.6mg/kg IM and Pentobarbital 100mg/kg IV. The frontonasal suture was removed from the rabbit and divided into hemisections. The right hemisection was histologically processed using standard ...
