Can Resilience Be Reconciled With Globalization And The Increasingly Complex Conditions Of Resource Degradation In Asian Coastal Regions?, Derek Armitage, Derek Johnson

Geography and Environmental Studies Faculty Publications

This paper explores the relationship between resilience and globalization. We are concerned, most importantly, with whether resilience is a suitable conceptual framework for natural resource management in the context of the rapid changes and disruptions that globalization causes in social-ecological systems. Although theoretical in scope, we ground this analysis using our experiences in two Asian coastal areas: Junagadh District in Gujarat State, India and Banawa Selatan, in Central Sulawesi, Indonesia. We present the histories of resource exploitation in the two areas, and we attempt to combine a resilience perspective with close attention to the impact of globalization. Our efforts serve …

Science For Place-Based Socioecological Management: Lessons From The Maya Forest (Chiapas And Petén), David Manuel-Navarrete, D. Scott Slocombe, Bruce Mitchell

Geography and Environmental Studies Faculty Publications

The role humans should play in conservation is a pervasive issue of debate in environmental thinking. Two long-established poles of this debate can be identified on a preservation-sustainable use continuum. At one extreme are use bans and natural science-based, top-down management for preservation. At the other extreme is community-based, multidisciplinary management for sustainable resource use and livelihoods. In this paper, we discuss and illustrate how these two strategies have competed and conflicted in conservation initiatives in the Maya forest (MF) of the Middle Usumacinta River watershed (Guatemala and Mexico). We further argue that both extremes have produced unconvincing results in …

The reentry vehicle is modeled as a point mass with constant aerodynamic properties as defined by the user. The equations of motion for reentry are based on the two-body problem. The atmosphere is modeled as a single layer exponentially decreasing in density. The MATLAB program has the ability to derive the initial trajectory conditions from the position and velocity relative to the rotating surface of the …

Forecasting Mental Health Care Cost For Oif And Oef Veterans, Phil Andrew L. Bernal

Theses and Dissertations

The war in Iraq has been the longest sustained ground combat that the US military has engaged since the Vietnam War. With the ongoing battle against the global war on terrorism, many military personnel will be deployed to hostile areas in support of these operations. The effects of multiple deployment and combat engagement on the mental health of military personnel have been extensively studied. The impacts of mental illnesses, such as PTSD, are tied to longer period in the combat zone. Meeting the psychiatric needs of these veterans will be costly: rehabilitation, retraining, post combat counseling, long-term medical treatment, and …

Analysis Of An Sirs Age-Structured Epidemic Model With Vaccination And Vertical Transmission Of Disease, Mohammed El-Doma

Applications and Applied Mathematics: An International Journal (AAM)

An SIRS age-structured epidemic model for a vertically as well as horizontally transmitted disease under vaccination is investigated when the fertility, mortality and removal rates depend on age and the force of infection of proportionate mixing assumption type, and vaccination wanes over time. We prove the existence and uniqueness of solution to the model equations, and show that solutions of the model equations depend continuously on the initial age-distributions. Furthermore, we determine the steady states and obtain an explicitly computable threshold condition, in terms of the demographic and epidemiological parameters of the model; we then study the stability of the …

Symbols Of Water And Woman On Selected Examples Of Modern Bengali Literature In The Context Of Mythological Tradition, Blanka Knotkova-Capkova

Wagadu: A Journal of Transnational Women's & Gender Studies

Woman-water homology appears in modern Bengali literature (namely poetry) in various aspects: as the archetypal symbol of creation and destruction, symbol of the womb as the beginning and end of life and rebirth (connoting both physical womb and eternal womb), and also of the womb as dark mysteriousness; a symbol of the continuation, preservation of life, symbol of transience and elusiveness, traditional male written poetic symbol of charm and beauty. In the demystifying, subversive (not only female) poetic imagination, it may also construct the symbol of eternal unity with the female principle, articulate a specific concept of female identity.

Genetic Factors Leading To Chronic Epstein–Barr Virus Infection And Nasopharyngeal Carcinoma In South East China: Study Design, Methods And Feasibility, Xiu Chan Guo, Kevin Scott, Yan Liu, Michael Dean, Victor David, George W.

O'Brien, Cheryl Winkler

Biology Faculty Articles

Nasopharyngeal carcinoma (NPC) is a complex disease caused by a combination of Epstein-Barr virus chronic infection, the environment and host genes in a multi-step process of carcinogenesis. The identity of genetic factors involved in the development of chronic Epstein-Barr virus infection and NPC remains elusive, however. Here, we describe a two-phase, population-based, case-control study of Han Chinese from Guangxi province, where the NPC incidence rate rises to a high of 25-50 per 100,000 individuals. Phase I, powered to detect single gene associations, enrolled 984 subjects to determine feasibility, to develop infrastructure and logistics and to determine error rates in sample …

Remarks On The Stability Of Some Size-Structured Population Models I: Changes In Vital Rates Due To Population Only, Mohammed El-Doma

Applications and Applied Mathematics: An International Journal (AAM)

We consider a size-structured population model that has been studied in Calsina et al. (2003). We propose a different approach that provides direct stability results, and we correct a stability result given therein. In addition, we obtain global stability results that have not been given in Calsina et al. (2003).

A Biopsychosocial Perspective Of Gulf War Illness: A Structural Model, Katherine N. Nguyen

Loma Linda University Electronic Theses, Dissertations & Projects

Veterans deployed during the Persian Gulf War in 1990-1991 report significantly more nonspecific symptoms and poorer health than their nondeployed peers. This amalgamation of chronic, multisymptom health complaints is commonly referred to as Gulf War Illness. There are two major theoretical models within the medical/health field that may help explain these symptoms: 1) the traditional biomedical model, and 2) the more recently evolved (late 1970’s) biopsychosocial model. Theorists have proposed two major causal pathways in studying the etiology of health complaints of Gulf War veterans, the physical pathway and the psychosocial pathway. In the present study, the biopsychosocial model was …

The Relationship Between High Sensitivity C-Reactive Protein, Metabolic Syndrome And Exercise, Micheline A. Vargas

Loma Linda University Electronic Theses, Dissertations & Projects

Background: It is well known that regular physical activity is associated with lower risk of chronic diseases such as diabetes and cardiovascular disease. Physical activity is also considered an important determinant of metabolic syndrome. All levels of metabolic syndrome, diabetes, and cardiovascular disease are thought to involve inflammation. Physical activity may reduce risk, at least in part, by modifying the inflammatory process. Recent studies have demonstrated an inverse relationship between inflammatory markers, such as high sensitivity C-reactive protein (hs-CRP), and physical activity. Elevated hs-CRP appears to be an independent predictor of both CVD and diabetes. Recent evidence also suggests that …

Membrane Organization And Multimeric Interactions Of The Aer Receptor In E. Coli, Divya Dashrathkumar Amin

Loma Linda University Electronic Theses, Dissertations & Projects

Escherichia coli swims toward niches ideal for generating maximum energy by monitoring the environment with the aerotaxis sensor, Aer. This receptor has an N-terminal PAS domain, which is a sensor module present in a variety of proteins from all kingdoms of life (including humans). To date, the mechanism of signaling from a PAS sensor domain to a single signaling receiver domain has not been resolved. In Aer, the PAS sensor is separated from the signaling region by a membrane anchor. Most "transmembrane prediction" programs forecast a single membrane span for this membrane anchor, but such a topology is inconsistent our …

The Healing Ministry Of Jesus As Recorded In The Synoptic Gospels, Alvin Lloyd Maragh

Loma Linda University Electronic Theses, Dissertations & Projects

This study explores the narratives in the healing ministry of Jesus as recorded in the synoptic gospels. The majority of the healing narratives address issues that transcend physical aspects and point to Jesus' attempt to restore the whole person. This is reflected in the fact that more than half of the healing narratives deal with the marginalized of society during Jesus' time. He healed demon possessed persons, beggars, lepers, women suffering from incurable diseases, and those who were racially discriminated against by the Jews. Other healing narratives deal with the understanding of faith, the message of forgiveness, and the meaning …

The Environmental Impact Of Dietary Choice And Agriculture In California, Harold J. Marlow Jr.

Loma Linda University Electronic Theses, Dissertations & Projects

Food demand influences agricultural production. Modern agricultural practices have resulted in polluted soil, air and water, eroded soil, dependence on imported oil, and loss of biodiversity. The goal of this research is to investigate the environmental impact of pesticide and fertilizer application, water consumption, and energy used to produce commodities for a vegetarian and non vegetarian diet in California. The working assumption is that greater number and amount of inputs are associated with greater environmental impact. The literature supports this notion. To accomplish this goal, dietary preferences were quantified using the Adventist Health Study and state agricultural data were collected …

Low Birth Weight, Very Low Birth Weight And Infant Mortality In San Bernardino County : A Secondary Analysis Of Maternal Factors, Rebecca D. Nanyonjo

Loma Linda University Electronic Theses, Dissertations & Projects

Purpose: National and state infant mortality rates have slowly declined over the last several years. Despite this reduction, San Bernardino County still has one of the highest infant mortality rates in California and racial disparities between Black and White infants not only persist but continue to widen. These disparities remain at the forefront of concern. Healthy People 2010 target objectives have yet to be reached, while national and state proposed plans have supported the statement that a community's largest health problem is initiated by its infant mortality. The purpose of this study was to investigate maternal factors through use of …

Effects Of Diabetes Mellitus On The Healing Of The Dental Pulp, Stuart Evan Garber

Loma Linda University Electronic Theses, Dissertations & Projects

Diabetes Mellitus (DM) has been implicated as a factor affecting healing. The purpose of this study was to use the healing of experimentally exposed pulps subsequent to pulp capping as a model to determine the effect of DM on healing.

Twenty-two Sprague-Dawley rats were divided into two groups of eleven animals each. In one group, DM was induced by injection of 70 mg/KG of streptozotocin. In the other group, the animals were injected with sterile saline. Under anesthesia with Ketamine and Xylazine, the pulps of the maxillary first molars of all rats were exposed using a 1/16 round bur under …

Factors That Influence The Blood Flow Response Of Skin To Electrical Stimulation, Abdul-Majeed Raja Al-Malty

Loma Linda University Electronic Theses, Dissertations & Projects

Female reproductive hormones, aging, global heating and local heating are factors affecting skin blood flow (SBF), but their effect on electrical stimulation (ES) has never been examined until the present investigation. To investigate female reproductive hormones, nine women (age= 25.6±3.5 years) with a normal menstrual cycle (MC) underwent ES in thermoneutral (25°±0.5°C) and warm environments (35°±0.5°C). To investigate aging, ES was applied on active young (n=15, age=32.1±8.3 years) and old (n=8, 64.5±6.2 years) groups in thermoneutral and warm environments. To investigate the effect of global and local heating, groups of 15 and 18 subjects (age= 18-40 years) experienced ES under …

Comparing Chemical Dependency And Mental Health Programs For The Dually Diagnosed, Kelly L. Hacker

Loma Linda University Electronic Theses, Dissertations & Projects

In order to better understand the needs of an increasing dually diagnosed population, this study compares the efficacy of integrated vs. nonintegrated treatment programs for a dually diagnosed population, residing at a Long Term Care facility in San Bernardino, California. Patients in this setting are diagnosed with chronic and acute mental illness and chemical dependency. This study tested the hypotheses that the nonintegrated treatment program would result in a higher frequency of assaults, PRNs, Q15s, and Code Reds; increase the duration of Q15s; and, increase the Addiction Severity Index’s (ASI) Family/Social and Psychiatric subscales’ scores, which would indicate lower levels …

Free Will To Will? A Case For The Recognition Of Intestacy Rights For Survivors To A Same-Sex Marriage Or Civil Union?, Christine A. Hammerle

Michigan Law Review

This Note argues that courts should recognize intestacy rights for same sex couples that were validly married or civilly united in a state other than the one in which one of the partners died. Courts may validly recognize the marriage for intestacy purposes, even while refusing to recognize the marriage as against public policy. Part I details the recent provision of benefits in various states to same-sex couples. Part II argues that same-sex couples cannot necessarily rely on wills to effectuate their intent to leave their property to their spouses. Part III argues that when states refuse to recognize the …
