Catalogue Of Acculturation Constructs: Descriptions Of 126 Taxonomies, 1918-2003, Floyd W. Rudmin

Online Readings in Psychology and Culture

Acculturation refers to the processes by which individuals, families, communities, and societies react to inter-cultural contact. Advances in communication and transportation technologies, and increasing migration pressures due to demographic, economic, environmental, human rights, and security disparities, make acculturation one of the most important topics for applied research in cross-cultural psychology. However, progress in acculturation research has been frustrated by our inabilities to pit theories against each other in meaningful ways, to summarize results by meta-analytic methods, or to improve constructs and scales all because we have been unaware of the interdisciplinary breadth of acculturation research and its historical depth. This …

Respect For Grizzly Bears: An Aboriginal Approach For Co-Existence And Resilience, Douglas A. Clarke, D. Scott Slocombe

Geography and Environmental Studies Faculty Publications

Aboriginal peoples’ respect for grizzly bear (Ursus arctos) is widely acknowledged, but rarely explored, in wildlife management discourse in northern Canada. Practices of respect expressed toward bears were observed and grouped into four categories: terminology, stories, reciprocity, and ritual. In the southwest Yukon, practices in all four categories form a coherent qualitative resource management system that may enhance the resilience of the bear-human system as a whole. This system also demonstrates the possibility of a previously unrecognized human role in maintaining productive riparian ecosystems and salmon runs, potentially providing a range of valued social-ecological outcomes. Practices of respect …

Clyde Kluckhohn And The New Anthropology: From Culture And Personality To The Scientific Study Of Values, John S. Gilkeson

Pacific Studies

This essay examines Clyde Kluckhohn’s relations with Ruth Benedict, Margaret Mead, and Gregory Bateson in two contexts: the school of culture and personality, and the Conference on Science, Philosophy, and Religion in Their Relation to the Democratic Way of Life convened during the Second World War. Kluckhohn strongly identified with the Boasian tradition. Enlisting in the Boasian campaign to make Americans more “culture-conscious,” Kluckhohn joined Benedict and Mead as a public intellectual. In this capacity, Kluckhohn sought to clarify the concept of culture and to widen its currency, emphasized the affinity between anthropology and psychiatry, and, after 1945, searched for …

Gene Order Phylogeny And The Evolution Of Methanogens, Haiwei Luo, Zhiyi Sun, William Arndt, Jian Shi, Robert Friedman, Jijun Tang

Faculty Publications

Methanogens are a phylogenetically diverse group belonging to Euryarchaeota. Previously, phylogenetic approaches using large datasets revealed that methanogens can be grouped into two classes, “Class I” and “Class II”. However, some deep relationships were not resolved. For instance, the monophyly of “Class I” methanogens, which consist of Methanopyrales, Methanobacteriales and Methanococcales, is disputable due to weak statistical support. In this study, we use MSOAR to identify common orthologous genes from eight methanogen species and a Thermococcale species (outgroup), and apply GRAPPA and FastME to compute distance-based gene order phylogeny. The gene order phylogeny supports two classes of methanogens, but it …

Relationships Associated With Long-Term Stepgrandmother Role Behavior, Role Meaning, And Satisfaction, Mary-Catherine. Kane

Dissertations

Remarriage from the mid-1970s through the mid-1990s has resulted in a stepgrandmother role behavior and role meaning, satisfaction with the stepgrandchild relationship, custody arrangements of minor stepchildren, and demographic information. Multiple linear regression revealed significant associations between several dyadic relationships (stepgrandmother-adult stepchild closeness and biological grandmotheradult child closeness) and stepgrandmother role behavior, role meaning and relationship satisfaction. One-way ANOVA revealed a significant difference on stepgrandmother role meaning for stepgrandmothers who lived in shared residential arrangements with the middle generation as minors. Implications for clinical practice, policy, and research are offered. growing cohort of stepmothers transitioning into stepgrandmotherhood. The complexity of …

When Self-Pacing Goes Wrong: A Comparison Of Two Methods For Reducing Computer-Based Racing, Douglas A. Johnson

Dissertations

Self-pacing, although often seen as one of the primary benefits of computer-based instruction (CBI), can also result in an important problem, namely, computer-based racing. Computer-based racing is when learners respond so quickly within CBI that mistakes are made, even on well-known material. This study compared traditional CBI with two forms of CBI designed to reduce computer-based racing: incentives/disincentives and postfeedback delays. All three formats were evaluated in terms of both performance and satisfaction using a between group repeated measures design with pretest and posttest. Dependent measures included posttest scores, satisfaction questionnaire ratings, percentage correct during learning, and total training time. …

African-American Girls And Scientific Argumentation: Lived Experiences, Intersecting Identities And Their Roles In Constructing And Evaluating Claims, Phyllis Haugabook Pennock

Dissertations

Scientific argumentation can be traced back to ancient times; yet has seen a recent upswing over the last decade in the area of science education. This is due to current national education standards that ascribe this practice as a way of promoting scientific literacy for all. Current literature reflects an evolution of scientific argumentation – accommodating emerging research that uses socio-scientific issues. National standards highlight the need to teach argumentation, yet also recognize the urgent demand for educational equity of all students.

The purpose of this research was to narrow the gap dividing argumentation studies from other science discourse research. …

Investigation Of Atmospheric Microplasma Jet For Nanofabrication, Konstantin Yurchenko

Theses

The last decade has seen an immense amount of research exploring advanced nanofabrication techniques. Many efforts on this front have moved closer to realization of industrially viable nanofabrication, i.e. nanomanufacturing. Plasma-assisted processes have proven to be particularly suitable for nanofabrication due to a non-equilibrium condition that offers high concentration of chemically reactive species at low gas temperatures. Recently, cost-effective atmospheric plasma technologies have been a subject of intense research. The possibility of producing plasma environments at atmospheric pressure similar to those found at low-pressure offer additional advantages for industrial implementation of nanofabrication processes and surface treatment. Atmospheric pressure equates to …

The Taming Of The Cat, Carlos A. Driscoll, Juliet Clutton-Brock, Andrew C. Kitchener, Stephen J. O'Brien

Biology Faculty Articles

This article discusses research into the evolution of domesticated cats, which is complicated by the fact that they do not appear to serve humans. Although several species are morphologically similar, genetic research focusing on mitochondrial DNA and genetic microsatellites found that domesticated cats descended from F. sylvestris lybica. Archaeological research indicating cats came to live with humans as the prevalence of house mice in agricultural settlements increased is noted.

Modeling And Analysis Of The Spread Of Japanese Encephalitis With Environmental Effects, Ram Naresh, Surabhi Pandey

Applications and Applied Mathematics: An International Journal (AAM)

A nonlinear mathematical model for the spread of Japanese Encephalitis, caused by infected mosquito feeding on susceptible human population incorporating demographic and environmental factors is proposed and analyzed. In the modeling process, it is assumed that the growth rates of reservoir animal population and vector mosquito population are enhanced due to environmental discharges caused by human population related factors. The model is analyzed by stability theory of differential equations and computer simulation. Both the disease-free and the endemic equilibria are found and their stability is investigated. It is found that whenever the disease-free equilibrium is locally asymptotically stable, the endemic …

Effects Of Hematocrit On Impedance And Shear Stress During Stenosed Artery Catheterization, V. P. Srivastava, Rati Rastogi

Applications and Applied Mathematics: An International Journal (AAM)

The flow of blood through a stenosed catheterized artery has been studied. To observe the effects of hematocrit, blood has been represented by a two-phase macroscopic model (i.e., a suspension of red cells in plasma). It is found that for any given catheter size, the impedance increases with hematocrit and also for a given hematocrit, the same increases with the catheter size. In the stenotic region, the wall shear stress increases in the upstream of the stenosis throat and decreases in the downstream in an uncatheterized artery but the same possesses an opposite character in the case of a catheterized …

Effect Of Glycocalyx On Red Blood Cell Motion In Capillary Surrounded By Tissue, Rekha Bali, Swati Mishra, P. N. Tandon

Applications and Applied Mathematics: An International Journal (AAM)

The aim of the paper is to develop a simple model for capillary tissue fluid exchange system to study the effect of glycocalyx layer on the single file flow of red cells. We have considered the channel version of an idealized Krogh capillary-tissue exchange system. The glycocalyx and the tissue are represented as porous layers with different property parametric values. Hydrodynamic Lubrication theory is used to compute the squeezing flow of plasma within the small gap between the cell and the glycocalyx layer symmetrically surrounded by the tissue. The system of non linear partial differential equations has been solved using …

Stability Of An Age-Structured Seir Epidemic Model With Infectivity In Latent Period, Xue-Zhi Li, Bin Fang

Applications and Applied Mathematics: An International Journal (AAM)

We study an age-structured SEIR epidemic model with infectivity in the latent period. By using the theory and methods of Differential and Integral Equations, the explicit expression for the basic reproductive number R₀ is first derived. It is shown that the disease-free equilibrium is locally and globally asymptotically stable if R₀ < 1. It is then proved that only one endemic equilibrium exists if R₀ > 1 and its stability conditions are also given.

Postnatal Maturation Modulates Cerebrovascular Myogenic Tone, Shelton M. Charles

Loma Linda University Electronic Theses, Dissertations & Projects

The present study focused on the main hypothesis that maturation decreases contractile reliance on calcium influx and myofilament Ca2+ sensitivity, and increases reliance on release of calcium from intracellular stores to develop and maintain pressure-evoked myogenic tone in rat cerebral blood vessels. To test this hypothesis, pressure-induced myogenic tone and changes in artery wall ([Ca2+]i) were measured simultaneously in isolated endothelium denuded, fura-2 loaded middle cerebral arteries (MCA) from pup (PI4) and adult (6 months old) SD rats. We studied the mechanism that govern myogenic tone and examined the hypothesis that during maturation, MCA from rat pups are more reliant …

A Psychoeducational Group Intervention For Fibromyalgia Patients, Derek O. Bacchus

Loma Linda University Electronic Theses, Dissertations & Projects

This study examined the effect of a multidisciplinary psychoeducational treatment group on Fibromyalgia Syndrome (FMS) pain, depression, catastrophizing, and quality of life. The Short-Form McGill Pain Questionnaire (SF-MPQ), Center for Epidemiologic Studies Depression Scale (CES-D), Coping Strategies Questionnaire (CSQ), and the World Health Organization Quality of Life Assessment—Abbreviated Version were used to assess these constructs in 15 participants. The sample was composed entirely of female participants and was predominantly middle aged, which is typical of the FMS population. Two separate groups of FMS patients—seven in Group 1, eight in Group 2—completed a 10-week psychoeducational intervention where they were presented with …

Effects Of Spaceflight On Phagocytic Function And Immune-Neural Interaction, Farnaz P. Baqai

Loma Linda University Electronic Theses, Dissertations & Projects

In spaceflight, astronauts will be exposed to several environmental risk factors that may lead to disturbances in homeostasis maintained by the central nervous system (CNS) and immune system. Low Earth orbit (LEO) spaceflight studies have shown that microgravity changes virtually all immune parameters that have been evaluated. Similarly, ground based studies have shown that low-dose radiation can also significantly impact immune function. Finally, as most spacecrafts are ecologically and environmentally closed systems, astronauts may be at increased risk for exposure to aerosolized infectious agents. The hypothesis of this study is: Exposure to spaceflight environment (microgravity and radiation) can influence immune …

Postprandial Effects Of Pecans Ingestion On Plasma Level Of Nutrients, Polyphenolic Compounds And Biomarkers Of Antioxidant Status In Human Volunteers, Chatrapa Hudthagosol

Loma Linda University Electronic Theses, Dissertations & Projects

Pecans (Carya illinoinensis) are rich sources of polyphenolic compounds and nutrients, which have antioxidant capacity results in favorable reductions in plasma lipids and lipoproteins. However, the health benefits of pecans may not be limited to blood lipid changes. There has been very little investigation into the contribution of bioactive components found in nuts to antioxidant protection. The purposes of the study were 1) to determine the impact of pecan consumption on concentration of total plasma polyphenols and their peak concentration over time. 2) to measure the effect of a pecan diet on postprandial levels of plasma lipid peroxidation …

Mnte-2-Pyp And Radiation In A Prostate Cancer Model: Implications For Radiotherapy, Adeola Y. Makinde

Loma Linda University Electronic Theses, Dissertations & Projects

A major limitation of successful radiation therapy in cancer treatment is the increase in normal tissue damage as higher doses are used to achieve greater tumor destruction. Radiation dose optimization in cancer therapy requires achieving maximum tumor destruction with minimal damage to normal tissue Antioxidants have been shown to protect normal tissues against radiation damage, as radiation-induced tissue damage results predominantly from reactive oxygen species that directly damage cellular components. However, for effective use as normal tissue radioprotectants in radiotherapy, these antioxidants must not protect the tumors. Mn (III) tetrakis (N-ethylpyridinium-2-yl) porphyrin (MnTE-2-PyP) is a metalloporphyrin antioxidant that has been …

Fetal Cocaine Exposure Causes Epigenetic Changes In The Rat Heart, Kurt D. Meyer

Loma Linda University Electronic Theses, Dissertations & Projects

Cocaine abuse continues to be prevalent in the United States and other industrialized nations, in addition to the negative health effects that cocaine abuse has on the user, a mother who uses cocaine while pregnant also exposes the developing fetus to cocaine. Although there have been many studies of the effects of cocaine on the adult heart, studies of cocaine on the fetal heart and its potential delayed pathophysiological effects on cardiac function in adult offspring are extremely limited. The studies of the present project sought to enhance the understanding of the effect of cocaine exposure on the fetal heart …

Localization And Expression Of The Aer Receptor In Escherichia Coli, Daniel Salcedo

Loma Linda University Electronic Theses, Dissertations & Projects

In Escherichia coli, chemotactic movement towards an energetically-favorable environment is mediated by five transmembrane chemoreceptors. These sensory proteins respond to numerous environmental signals, including amino acids, sugars, and pH. The aerotaxis receptor, Aer, is an intracellular sensor that responds to oxygen concentration and other parameters affecting cellular energy levels. Bacterial chemotaxis receptors form dimeric signaling units that organize into tetramers and hexamers and form large clusters at the cell poles. A cluster arrangement could increase receptor sensitivity by lateral communication between dimers, thus amplifying the signal from one dimer. We have shown that Aer forms dimers, trimer of dimers, …

The Effects Of A Psychoneuroimmunology Based Lifestyle Intervention In Modifying The Progression Of Major Depression In Clinically Depressed Adults, Ruth A. Tanyi

Loma Linda University Electronic Theses, Dissertations & Projects

Chronic stress can lead to poorly controlled upsurges of cortisol and dysregulation of the hypothalamic pituitary-adrenal axis, thereby contributing to major depression. Hence, researchers have begun to examine the effects of individual psychoneuroimmunology (PNI) interventions and their impact on modifying stress and depression. However, there is a lack of studies that have examined the composite effect(s) of a PNI-based lifestyle intervention and major depression. Thus, this randomized interventional study examined the composite effect(s) of a PNI-based lifestyle intervention: combined progressive muscle relaxation and spiritual guided imagery and humor as an adjunct therapy to modifying the progression of depression. Participants were …

Anthropometric Parameters Of Under-Five Years Old Children With Different Dietary Habits In Ukambani Region : A Study In Eastern Rural Kenya, Hellen M. Ndiku

Loma Linda University Electronic Theses, Dissertations & Projects

The objective of this descriptive cross sectional study was to assess dietary intake and nutritional status of children under-five years in two rural sites of Eastern Kenya where the staple cereals may differ. A modified rapid, knowledge, practice and coverage (KPC) questionnaire and a 24-hr dietary recall form were used to collect the data. A total of 403 households were surveyed from four randomly selected divisions. This yielded 629 surrogate 24-hr dietary recalls of children < 5 years with 314 from Mwingi district and 315 from Makueni district (49 % boys and 51 % girls).

Statistical analysis was done using SPSS and SAS. Comparison of means was done using t- test and chi square was used for proportions. The 24-hr …

Detecting, Preventing, And Treating Sexually Transmitted Diseases Among Adolescent Arrestees: An Unmet Public Health Need, Steven Belenko, Richard Dembo, Matthew Rollie, Kristina Childs, Christopher Salvatore

Department of Justice Studies Faculty Scholarship and Creative Works

Studies of detained and incarcerated adolescent offenders in the United States indicate that these juveniles have an elevated risk of sexually transmitted diseases (STDs). However, many more arrestees enter the “front end” of the juvenile justice system that is detained or incarcerated, and research into the STD risk profiles and service needs of this larger group is lacking. An expansion of STD testing (including of asymptomatic youths), prevention, and treatment is needed, as is improved knowledge about gender- and race-specific services. A pilot program in Florida has shown that juvenile justice and public health systems can collaborate to implement STD …

Educational Leaders Perceptions Of Emotional Intelligence And How It Effects Their Professional Practice, Yaffa Krugliak Lahat

College of Education Theses and Dissertations

Researchers argue that Emotional Intelligence (EI) plays a key role in effective and successful leadership (Goleman et al., 2004; Rosete & Ciarrochi, 2005; Chan, 2007). Although other researchers claimed that these assertions lean "little empirical support" (Ciarrochi, Deane & Anderson, 2002), Goleman, Boyatzis, and McKee (2004) assert that EI is essential for leadership because leaders work through emotions and their primal job is emotional. With most of this research done in the business world, this study focuses on the role of EI in educational leadership. The purposes of this study are to explore and to construct new knowledge regarding educational …

A New Model Of Productive Online Discussion And Its Implications For Research And Instruction, Fei Gao, Charles Xiaoxue Wang, Yanling Sun

Journal of Educational Technology Development and Exchange (JETDE)

We develop a new model of productive online discussion based on a brief review of research literature on online discussion. As compared to previous discussion models, the new model provides a more systematic and comprehensive framework to understand how learning occurs through online discussion. Based on the new model, we propose several directions for research on improving the quality of online discussion and learning.

An Evolving Practice Model In The Development Of Lifelong Education For Senior Citizens, Wai Chuen Shum

APIAS Monograph 專題論文

Promoting productive and successful aging has gradually become a main concern for society at large, in particular, public policy makers, gerontologists and social workers in ageing societies. In Hong Kong, the population aged 60 years and above has increased from 745,500 (13% of the total population) in 1991 to 1,004,400 (14.8%) in 2001 (Census & Statistics Department 2005). This figure will increase to about 2.2 million representing 27.7% of the population by 2023 within a span of about twenty years (Census & Statistics Department 2004). With this rapid growth of the elderly population, greater efforts are urgently needed to prepare …
