An Evaluation Of Interventions Designed To Impact Nurses : A Pilot Project, Pamela G. Bing Perry Jun 2009

An Evaluation Of Interventions Designed To Impact Nurses : A Pilot Project, Pamela G. Bing Perry

Loma Linda University Electronic Theses, Dissertations & Projects

This pilot project was designed from a systems approach as defined within the field of marriage and family (MFT). Systems theory has been used successfully in examining and working with organizational relationships as exemplified in the work of Edwin H. Friedman. His contribution includes several books specifically developed for use in organizations; one that was tailored for religious groups; and another for managers (Friedman, 2007). While other MFT modalities have also been used effectively with organizations, the complexity of the influences operating within an organization most closely matches the systems approach. For this reason, this is the conceptual framework applied …

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 Jun 2009

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 Jun 2009

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 …


Accuracy Of A Rationally-Derived Method For Predicting Failure In Residential Treatment, Jennifer Pester Grattan Jun 2009

Accuracy Of A Rationally-Derived Method For Predicting Failure In Residential Treatment, Jennifer Pester Grattan

Loma Linda University Electronic Theses, Dissertations & Projects

Recent studies of adult mental health treatment have used patient-focused research methods to improve outcomes, by tracking treatment response and comparing it with expected recovery patterns. One such line of research has used rationally-derived and empirically-derived methods to analyze data gathered by the OQ-45 and identify patients who are not responding as expected to treatment. This allows for adjustment of treatment, which results in improved outcomes and lower overall costs.

Similar but less extensive research has provided evidence that these approaches may also improve outcomes in outpatient treatment for children and adolescents. These approaches might be particularly useful in residential …

The Influence Of Familism On Descriptive And Injunctive Norms In Predicting The Intention To Eat A Vegetarian Diet Among Chinese Seventh-Day Adventists, See Wei Toh Jan 2009

The Influence Of Familism On Descriptive And Injunctive Norms In Predicting The Intention To Eat A Vegetarian Diet Among Chinese Seventh-Day Adventists, See Wei Toh

Loma Linda University Electronic Theses, Dissertations & Projects

According to the theory of planned behavior (TpB), one determinant of intention to engage in a behavior is the subjective norm. Various studies have found that subjective norm is often the weaker predictor of intention compared to perceived behavioral control and attitude. This study examined whether familism (emphasis on the family rather than the individual) would contribute positively to the predictive power of the TpB model through interactions with the family portion of descriptive and injunctive norms. Descriptive and injunctive norms are component variables of the subjective norm. A sample of 284 adult Chinese Seventh-day Adventists 18 years and older …


Psychological Distress And Change In A Pediatric Obesity Population, Amy Rebecca Beck Dec 2008

Ethical Decision-Making Regarding Multiple Relationships Between Therapist And Client, Diana Jochai Dec 2008

Ethical Decision-Making Regarding Multiple Relationships Between Therapist And Client, Diana Jochai

Loma Linda University Electronic Theses, Dissertations & Projects

The current study examined a new conceptual model of factors critical to a therapist’s decision-making process when faced with the potential of a nonsexual multiple relationship with a client. This new model was founded on the conceptual framework proposed by Street, Douglas, Geiger, & Martinko (2001) and integrated the components of the decision-making process and the individual and situational factors influencing those components identified in existing general conceptual models and specific behavioral guidelines. For the ethical decision-making process to begin, a practitioner must be able to recognize the presenting problem as an ethical dilemma (Brazerman, 1986; Jones, 1991; Street et …
