Marital Quality And Health Over 20 Years: A Growth Curve Analysis, Richard B. Miller, Cody S. Hollist, Joseph Olsen, David Law Jun 2013

Marital Quality And Health Over 20 Years: A Growth Curve Analysis, Richard B. Miller, Cody S. Hollist, Joseph Olsen, David Law

Department of Child, Youth, and Family Studies: Faculty Publications

Although there is substantial evidence linking marital quality to physical health, few studies have been longitudinal. This study examined data from the Marital Instability Over the Life Course Study; 1,681 married individuals followed for 20 years were included in these analyses. In order to control for life course effects, participants were divided into 2 cohorts: early life and midlife. On the basis of latent growth curve analysis, the results indicated that initial values of marital happiness and marital problems were significantly associated with the initial value of physical health among both cohorts. In addition, the slope of marital happiness was …


Executive Functions And Social Interactions: Developing Social Scenarios, Mackenzie Waite Jun 2013

Executive Functions And Social Interactions: Developing Social Scenarios, Mackenzie Waite

Masters Theses

The aim of this study was to develop a series of vignettes to form the basis for an assessment of executive functions (EFs) for 9 – 12 year old children. Although EFs are necessary for effective social communication and positive social interactions, currently, most EF assessments focus on impersonal activities. Little research exists that incorporates real-time processing using ecologically valid social scenarios. The current study aims to develop realistic scenarios that children could encounter in daily life. Ethnographic interviews were conducted with six participants, who worked in a school with 9-12 year old children, to gain their perspective on social …


Motivational Interviewing Assessment And Behavior Therapy As A Stepped-Care Approach To The Treatment Of Adolescent Depression, Tanya N. Douleh Jun 2013

Motivational Interviewing Assessment And Behavior Therapy As A Stepped-Care Approach To The Treatment Of Adolescent Depression, Tanya N. Douleh

Dissertations

Depression is a significant public health concern with a lifetime prevalence of 24.01 for adolescents in grades 9-12 (Lewinsohn, Hops, Roberts, Seeley, & Andrews, 1993) and a point prevalence of 4-6% (Kessler, Avenevoli, & Ries, 2001). The risks associated with adolescent onset depression include comorbidity, depressive episodes continuing into adulthood, and suicidality. These risks make it imperative to develop effective treatments to address adolescent depression. Stepped care is an approach to treatment which involves treatment of illness using the least invasive measures first and moving toward more invasive treatment as indicated by ongoing assessment. Through a single-participant design, the current …


Reconceiving Self-Abnegation: Female Vulnerability As Embodied (Un)Sovereignty, Renee Lee Gardner Jun 2013

Reconceiving Self-Abnegation: Female Vulnerability As Embodied (Un)Sovereignty, Renee Lee Gardner

Dissertations

Liberal feminism views vulnerability as weakness and dominance as strength. This binary parallels nationalistic assertions of sovereignty. Within militaristic responses such as the U.S. retaliation to 9/11, however, we see the cost of refusing to acknowledge our vulnerability. In my analysis of eleven novels arising from eight distinct nation-states and representing historical moments from the final decades of slavery through the early post- 9/11 years, I use alternative (queer, postcolonial, Islamic) feminisms to read power in vulnerability. I explore female characters who deliberately self-abnegate – sacrificing their lives, bodies, voices, and children – but whose actions can be read as …


Discovery And Characterization Of A Tanapoxvirus Encoded Human Neuregulin Mimetic, David Jeng Jun 2013

Discovery And Characterization Of A Tanapoxvirus Encoded Human Neuregulin Mimetic, David Jeng

Dissertations

Studies on large dsDNA viruses such as poxviruses have been helpful in identifying a number of viral and cellular growth factors that contribute to our broad understanding of virus-host interaction. Orthopoxviruses and leporipoxviruses are among the most studied viruses in this aspect. However, tanapoxvirus (TPV) a member of the genus Yatapoxvirus, still remains largely unexplored, as the only known hosts for this virus are humans and monkeys. Here, we describe the initial characterization of an EGF-like growth factor mimicking human neuregulin from TPV, expressed by the TPV-15L gene. Assays using a baculovirus expressed and tagged TPV-15L protein demonstrated the ability …


A Discursive Analysis Of A Pregnancy Center: How Pregnant Women Are Encouraged To Develop A Sense Of Self-Worth And Emotional Wellbeing Through The Use Of Rhetoric And Imagery, Jessica Postma Jun 2013

A Discursive Analysis Of A Pregnancy Center: How Pregnant Women Are Encouraged To Develop A Sense Of Self-Worth And Emotional Wellbeing Through The Use Of Rhetoric And Imagery, Jessica Postma

Masters Theses

This study presents and alternative approach to how pregnancy is interpreted in western society and how settings such as a pregnancy center both challenges and reinforces these social standards. The promotion of abstinence, the aversion to abortion, notions of truth and morality, religious narratives, and the standard of care are all integral components to this analysis of pregnancy, language, and culture.

Computing Foundations For The Scientist, Catherine Bareiss, Larry Vail Jun 2013

Computing Foundations For The Scientist, Catherine Bareiss, Larry Vail

ACMS Conference Proceedings 2013

There is a need for a new style of supporting a computer course. Although it is widely recognized that computer technology provides essential tools for all current scientific work, few university curricula adequately ground science majors in the fundamentals that underlie this technology. Introducing science students to computational thinking in the areas of algorithms and data structures, data representation and accuracy, abstraction, performance issues, and database concepts can enable future scientists to become intelligent, creative and effective users of this technology. The intent of this course is not to turn scientists into computer scientists, but rather to enhance their ability …


A Different Approach, Catherine Crockett Jun 2013

A Different Approach, Catherine Crockett

ACMS Conference Proceedings 2013

This paper discusses an approach used to encourage science majors to rethink their attitudes and study habits in a first semester calculus course. Two activities were used to enhance study habits. They are outlining concepts and in-class quizzes designed for self-evaluation of skills. After using both methods in two sections of the calculus course, the students were surveyed to determine if these activities were successful. A majority of the students felt the activities were helpful and wanted to continue them.


Reading Assignments And Assessments: Are Your Students Reading Math Texts Before Class, After Class, Both, Or Neither?, David Klanderman, Mandi Maxwell, Sharon Robbert, Bill Boerman-Cornell Jun 2013

Reading Assignments And Assessments: Are Your Students Reading Math Texts Before Class, After Class, Both, Or Neither?, David Klanderman, Mandi Maxwell, Sharon Robbert, Bill Boerman-Cornell

ACMS Conference Proceedings 2013

In his recent book What the Best College Students Do [Bain, 2012], Ken Bain defines a number of different types of students including “surface learners,” “strategic learners,” “routine experts,” and finally, “deep learners.” In our mathematics courses at Trinity, we have found examples of all of these student types. A major determinant of their preferred approach to learning appears to be the ways and degrees to which mathematical texts and other written materials are read prior to class sessions. Each full-time member of the department both assigns and assesses the reading of mathematical materials prior to class sessions. Assessment methods, …


Allelopathy As An Emergent, Exploitable Public Good In The Bloom-Forming Microalga Prymnesium Parvum, William W. Driscoll, Noelle J. Espinosa, Omar T. Eldakar, Jeremiah D. Hackett Jun 2013

Allelopathy As An Emergent, Exploitable Public Good In The Bloom-Forming Microalga Prymnesium Parvum, William W. Driscoll, Noelle J. Espinosa, Omar T. Eldakar, Jeremiah D. Hackett

Biology Faculty Articles

Many microbes cooperatively secrete extracellular products that favorably modify their environment. Consistent with social evolution theory, structured habitats play a role in maintaining these traits in microbial model systems, by localizing the benefits and separating strains that invest in these products from ‘cheater’ strains that benefit without paying the cost. It is thus surprising that many unicellular, well-mixed microalgal populations invest in extracellular toxins that confer ecological benefits upon the entire population, for example, by eliminating nutrient competitors (allelopathy). Here we test the hypotheses that microalgal exotoxins are (1) exploitable public goods that benefit all cells, regardless of investment, or …


Global Dynamics Of A Water-Borne Disease Model With Multiple Transmission Pathways, Prasanta K. Mondal, T. K. Kar Jun 2013

Global Dynamics Of A Water-Borne Disease Model With Multiple Transmission Pathways, Prasanta K. Mondal, T. K. Kar

Applications and Applied Mathematics: An International Journal (AAM)

We propose and analyze a water born disease model introducing water-to-person and person-toperson transmission and saturated incidence. The disease-free equilibrium and the existence criterion of endemic equilibrium are investigated. Trans critical bifurcation at the disease-free equilibrium is obtained when the basic reproductive number is one. The local stability of both the equilibria is shown and a Lyapunov functional approach is also applied to explore the global stability of the system around the equilibria. We display the effects of pathogen contaminated water and infection through contact on the system dynamics in the absence of person-to-person contact as well as in the …


Vegf And Sympathetic Perivascular Nerves Contribute To Hypoxic Remodeling Of Ovine Cranial Arteries, Olayemi Olufikayo Adeoye Jun 2013

Vegf And Sympathetic Perivascular Nerves Contribute To Hypoxic Remodeling Of Ovine Cranial Arteries, Olayemi Olufikayo Adeoye

Loma Linda University Electronic Theses, Dissertations & Projects

Chronic hypoxia complicates many pregnancies and can result in postnatal pathologies that include compromised fetal cardiovascular structure and function. Mechanisms involved remain unclear. Because hypoxia increases production of VEGF, known to modulate smooth muscle (SM) phenotype, this thesis explored the hypothesis that VEGF contributes to hypoxic fetal vascular remodeling through direct effects on SM cells and indirectly through perivascular nerves. Using a chronic hypoxia sheep model, this work demonstrated that: 1) hypoxia potently upregulates VEGF receptor expression but not endogenous VEGF level in fetal ovine carotid arteries; 2) both chronic hypoxia and VEGF exert similar effects on smooth muscle contractile …


Sleep-Wake Cycle Assessment In Type 2 Diabetes And Salivary Melatonin Correlates, Paula Regina Aguiar Cavalcanti Jun 2013

Sleep-Wake Cycle Assessment In Type 2 Diabetes And Salivary Melatonin Correlates, Paula Regina Aguiar Cavalcanti

Loma Linda University Electronic Theses, Dissertations & Projects

p=.047). Additionally, there were significant inverse relationships between melatonin collected at two hours before bed time and latency (ρ=-.87; p=.001), wake after sleep onset (ρ =-.69; p=.02) and nocturnal activity (ρ =-.67; p=.03). Latency was inversely correlated with melatonin collected at bed time (ρ =-.69; p=.02). These findings suggest that T2DM presents disturbances in the homeostatic and circadian drives, mainly characterized by less consistency across days of the daily circadian signal, higher rhythm fragmentation and lower rhythm amplitude. In addition to the lower melatonin levels, the decrease in the amplitude of the activity rhythm may also be involved in circadian …


Effects Of Proton Radiation And Pomegranates On Hippocampus And Behavior, Melissa S. Dulcich Jun 2013

Effects Of Proton Radiation And Pomegranates On Hippocampus And Behavior, Melissa S. Dulcich

Loma Linda University Electronic Theses, Dissertations & Projects

Exposure to ionizing radiation may have deleterious effects on physical and mental health, with an increased risk of proton radiation for astronauts traveling outside Earth's atmosphere into lower earth orbit. In animal models, radiation has been shown to suppress neurogenesis in the subgranular zone of the hippocampus, a key area for learning and memory. Furthermore, some evidence suggests that compounds found in fruits and vegetables (e.g. polyphenols) may offer some protection against the cellular effects of radiation. Few studies have looked at the effects of proton radiation on the central nervous system, even though proton radiation is the most prevalent …


Buffering Effect Of Relational Support In African American Marriages, Aimee Galick Jun 2013

Buffering Effect Of Relational Support In African American Marriages, Aimee Galick

Loma Linda University Electronic Theses, Dissertations & Projects

Racial discrimination is a common experience for African Americans in this country. Racial discrimination can have a negative effect on the physical and mental health of marital partners, as well the quality and stability of the relationship. Few studies investigate relational support as an important coping strategy. Bodenmann's (1995) divorce-stress model asserts that positive dyadic coping strategies such as relational support can buffer partners and marriages from the negative consequences of stress. Socio-emotional relational therapy (SERT) provides marital and family therapists with a model of relational support in couple relationships. SERT's definition formed the basis for the conceptualization of relational …


Effect Of Procedural Pain On Purines, Mda And Allantoin In Premature Infants, Megan Sue Holden Jun 2013

Effect Of Procedural Pain On Purines, Mda And Allantoin In Premature Infants, Megan Sue Holden

Loma Linda University Electronic Theses, Dissertations & Projects

Identifying and measuring the biochemical effects of procedural pain in infants is a continuing challenge for clinicians. To address this issue we evaluated the relationship between procedural pain, ATP utilization (hypoxanthine and uric acid), and oxidative stress (MDA and allantoin) in premature infants. Through these studies we found that 1) a single heel-lance significantly increases plasma uric acid in rabbit kits, 2) tape removal increases MDA and prevents a decrease in uric acid in the plasma of premature infants, and 3) a single dose of oral sucrose before a heel-lance is sufficient to significantly increase plasma markers of ATP utilization …


Small Molecule Inhibitors Of Hpv16 E6, Chung-Hsiang Yuan Jun 2013

Small Molecule Inhibitors Of Hpv16 E6, Chung-Hsiang Yuan

Loma Linda University Electronic Theses, Dissertations & Projects

High-risk human papillomaviruses (HR-HPVs) cause nearly all cases of cervical cancer. HPV 16 E6, one of two viral oncogenes, protects cells from apoptosis by binding to and accelerating the degradation of several apoptotic proteins, including caspase 8 and p53. We proposed that blocking the interactions between HPV E6 and its partners using small molecules had the potential to re-sensitize HPV+ cells to apoptosis. To test this prediction, we screened libraries of small molecules for candidates that could block E6/caspase 8 binding, and identified several candidates from different chemical classes. Testing hits for dose-dependency and specificity in vitro and for toxicity …


The Public Health Impact Of Maternal Smoking Cessation During Pregnancy : The San Bernardino County Experience, Michael Batech Jun 2013

The Public Health Impact Of Maternal Smoking Cessation During Pregnancy : The San Bernardino County Experience, Michael Batech

Loma Linda University Electronic Theses, Dissertations & Projects

Most studies of maternal tobacco cessation during pregnancy have estimated measures of effect that can be useful in identifying the exposure as an etiologic risk factor in maternal and child health. However, in the case of maternal tobacco use there is overwhelming evidence for a causal role in adverse infant outcomes, and public health needs to focus on measures of potential impact in order to better prioritize and allocate resources toward interventions. The aims of this dissertation were: 1) to investigate the public health impact of smoking cessation during pregnancy among mothers giving birth in San Bernardino County, California; and …


Role Of Igf-Ii, Prl, And Fabps In The Breast Cancer Disparity Among Aa Women, Teleka Cassandra Patrick Jun 2013

Role Of Igf-Ii, Prl, And Fabps In The Breast Cancer Disparity Among Aa Women, Teleka Cassandra Patrick

Loma Linda University Electronic Theses, Dissertations & Projects

It is well documented that African-American (AA) patients present with more advanced states of breast cancer and have lower survival rates than Caucasian-Americans (CA). Epidemiological data have shown that pregnancy and lactation at an early age in humans reduce the risk of breast cancer. Studies in mice and rats have shown that lactation stimulates the expression of intracellular fatty-acid binding protein 3 (FABP3). FABP3 is detected in human breast tissue and is known as mammary-derived growth inhibitor (MDGI) because it has a strong inhibitory effect on cell proliferation. FABP5 is also expressed in the breast, and has been associated with …


Sexual Trauma, Attachment, And Dissociation In Eating Disorder Populations, Kelly Cauley Rivinius Jun 2013

Sexual Trauma, Attachment, And Dissociation In Eating Disorder Populations, Kelly Cauley Rivinius

Loma Linda University Electronic Theses, Dissertations & Projects

The current study examined the process by which attachment influences dissociation in the presence of sexual trauma history. Sixty-two female individuals completed measures of attachment, trauma, and dissociation as a part of the intake assessment process the first week of their admission to a partial hospitalization program for treatment of an eating disorder. These archival data (2006 – 2013) were hand scored and coded by the researcher to ensure consistency across measures. Multiple mediations in parallel and moderated mediations in parallel were run using Hayes’ (2012) bootstrapping PROCESS macros. Consistent with predictions derived from the literature, sexual trauma significantly predicted …


Stress, Depression, Quality Of Life, And Language Recovery In Constraint Induced Aphasia Therapy (Ciat), Brian Sharp Jun 2013

Stress, Depression, Quality Of Life, And Language Recovery In Constraint Induced Aphasia Therapy (Ciat), Brian Sharp

Loma Linda University Electronic Theses, Dissertations & Projects

Traditional aphasia treatment approaches focus initially on restoration of language, but quickly move to use of alternative modes of communication when progress is slow. Constraint Induced Aphasia Therapy (CIAT), a more intensive form of treatment, is based on the concept of frequent, long sessions and forced use of the impaired language system. Prior to the present study, the relationship between CIAT and stress had not been explored; therefore, this study compared cortisol stress levels and improvement of language skills in two groups of subjects, all of whom presented with expressive aphasia. Ten subjects participated in CIAT, and received 10 days …


Family Resilience Model Of Behavioral Health For Low-Income Ethnic Minority Families, Sherria Donae Taylor Jun 2013

Family Resilience Model Of Behavioral Health For Low-Income Ethnic Minority Families, Sherria Donae Taylor

Loma Linda University Electronic Theses, Dissertations & Projects

Over the past decade, the concepts of relational and family resilience have emerged as topics of interest in family science. Individual, family, and community level determinants of family resilience have received increased amount of attention in family resilience research particularly among low-income minority families. Correlates of poverty among minority families that have been noted in the literature are that of substance abuse and lower levels of mental health. The primary aim of this study was to operationalize the concept of family resilience and develop an empirically-based model of family resilience. The secondary aim, as it relates to the epidemics of …


Microglia And Complement In Alzheimer's Disease With Cerebral Amyloid Angiopathy, Matthew K. Zabel Jun 2013

Microglia And Complement In Alzheimer's Disease With Cerebral Amyloid Angiopathy, Matthew K. Zabel

Loma Linda University Electronic Theses, Dissertations & Projects

Alzheimer’s disease (AD) is the most common form of dementia and completely lacks any viable, long-term therapeutic intervention. This is partly due to an incomplete understanding of AD etiology and the possible confounding factors associated with its genotypic and phenotypic heterogeneity. Cerebral amyloid angiopathy (CAA) is a common, yet frequently overlooked, pathology associated with AD. A pathological hallmark of AD consists of extracellular amyloid-beta (Aβ) deposits, while CAA

manifests with deposition Aβ within the smooth muscle layer of cerebral arteries and arterioles. The role of Aβ in AD and CAA pathophysiology has long been controversial. Although it may have toxic …


Physician Couples: A Qualitative Inquiry Focused On Gendered Power And Marital Equality, Sarah C. Stuchell Jun 2013

Physician Couples: A Qualitative Inquiry Focused On Gendered Power And Marital Equality, Sarah C. Stuchell

Loma Linda University Electronic Theses, Dissertations & Projects

How couples “do” gender and power in their marriages is a relevant topic for today’s couples. Despite social changes toward equality in many realms, gender continues to organize relationships in ways that give husbands more power than wives. However, some contemporary couples make conscious decisions to resist forces toward organizing according to stereotypical gender ideals and to “do” gender differently in their relationships. For couples in which one or both is a physician, power is also deeply embedded in the physician status, with families tending to organize around the physician’s demands. While these effects reinforce male dominance when the husband …


Ontogeny Of Venom Use And Venom Composition In The Western Widow Spider Latrodectus Hesperus, David Roger Nelsen Jun 2013

Ontogeny Of Venom Use And Venom Composition In The Western Widow Spider Latrodectus Hesperus, David Roger Nelsen

Loma Linda University Electronic Theses, Dissertations & Projects

I investigated the behavioral ecology of venom and venom use by the western widow spider (Latrodectus hesperus), emphasizing the role of ontogeny. In an introductory paper, I reviewed existing definitions of venom and poison, and refined these by adding a third category of toxic biological secretions: toxungen. These three can be distinguished by mode of toxin delivery and presence of a wound. In the first of four empirical studies, I investigated venom use by adult females in the context of threat assessment. A single brief poke at the lowest threat level elicited primarily avoidance responses ("move" and "retract"), repeated prodding …


Maternal Smoking, Weight Status And Preecalmpsia And Eclampsia Risk Among Women Living In San Bernardino County, Fiona Bedelia Lewis Jun 2013

Maternal Smoking, Weight Status And Preecalmpsia And Eclampsia Risk Among Women Living In San Bernardino County, Fiona Bedelia Lewis

Loma Linda University Electronic Theses, Dissertations & Projects

Preeclampsia is defined as pregnancy-induced hypertension affecting between 2% and 8% of pregnancies and accounting for about 10-15% of maternal deaths worldwide. Eclampsia is defined as the occurrence of one or more episodes of seizures in a pregnant woman related only to a preeclampsia diagnosis. Preeclampsia, if poorly managed, can progress to eclampsia resulting in injury and death to both mother and infant. The etiology of preeclampsia is not completely understood. Oxidative stress leading to abnormal placenta development and endothelial dysfunction are thought to be key components in the biological mechanism of preeclampsia.

Modifiable risk factors include maternal body weight …


Perinatal Nicotine Exposure And Programming Of Hie Sensitive Phenotype In Neonatal Rat Brains, Yong Li Jun 2013

Perinatal Nicotine Exposure And Programming Of Hie Sensitive Phenotype In Neonatal Rat Brains, Yong Li

Loma Linda University Electronic Theses, Dissertations & Projects

Large epidemiological and animal studies have revealed a clear association of adverse intrauterine environment with the increased risk of metabolic, cardiovascular and neurological diseases. Maternal smoking is the single most widespread perinatal insult in the world and has been associated with adverse pregnancy outcomes for mother, fetus and the newborn. Our study aims to test the hypothesis that perinatal nicotine exposure induces reprogramming of susceptibility to hypoxic ischemic brain injury in the immature brain, focusing on the roles of AT1R and/or AT2R and trying to reveal the underlying epigenetic mechanisms. Therefore, we established two rat models: perinatal nicotine exposure model …
