Impact Of Gums On The Growth, Viability, And Enzyme Activity Of Lactobacillus Species, Bernice D. Karlton-Senaye

Dissertations

This study investigated the impact of ten selected gums (carrageenan, carrageenan-maltodextrin, guar, locust bean, pectin, pectin- dextrose, pectin-carrageenan, guar-locust bean-carrageenan, inulin, and xanthan) on the growth of eight Lactobacillus strains in laboratory media. The bacterial population for eight Lactobacillus strains was determined in modified basal media at different concentration (0%, 0.25% and 0.5% w/v) of gums stored up to 12 hours at 37 °C. Findings show significant differences (p < 0.05) between the treated and control sample. Guar was found to be the best gum to enhance growth of L. rhamnosus GG B101, L. rhamnosus GG B101, L. delbrueckii subsp. bulgaricus SD35, L. delbrueckii subsp. bulgaricus SD33, L. acidophilus SD 16, L. acidophilus EF7, L. reuteri DSM20016, L. reuteri CF2-2F during 12 hours of storage at 37 C in laboratory media. The population of L. rhamnosus GGB101 in the samples containing gums were significantly (p < 0.05) higher than the control without gums. Samples containing 0.5% gums showed slightly higher bacterial population than those with 0.25% of gum. A minimum of 12 hour of incubation period was shown to be adequate to reach a bacterial population of 6 log CFU/mL in the presence of gums. Addition of guar (0.5%) led to the highest (1.31 log CFU/mL) increase in population of the treated L. rhamnosus GGB101 over the control. There was no marked (p < 0.05) change in pH and titratable acidity. Four different gums (carrageenan, carrageenan-maltodextrin, pectin-carrageenan, guar-locust bean-carrageenan) were selected to determine the effect on the growth, viability and betagalactosidase activity of four selected Lactobacillus strains (L. rhamnosus GG B101, L. rhamnosus GG B101, L. reuteri DSM20016, L. reuteri CF2-2F). Effect of the four selected gums on thegrowth L. rhamnosus GG B101, L. rhamnosus GG B101, L. reuteri DSM20016 in milk were compared to those in modified basal media. Results showed that xanthan induced highest growth of L. rhamnosus GG B103, L. rhamnosus GG B101 in milk whereas carrageenanmaltodextrin led to highest growth of L. reuteri DSM 20016 in the media. Marked differences (p < 0.05) in viability were observed between milk samples containing gums and the control. The presence of carrageenan-maltodextrin led to the highest viable counts (8.76 ± 0.03 log CFU/mL) of L. rhamnosus GGB103 during storage. The average population of L. rhamnosus GGB101 and Lactobacillus rhamnosus GGB103 was 8 log CFU/mL, whereas that of Lactobacillus reuteri DSM20016 and Lactobacillus reuteri SD2112 decreased slightly ( 0.15-0.64 log CFU/mL) to 7 log CFU/mL during the storage period. Viable counts were retained at 7-8 log CFU with no significant difference in the control versus treated strains except in the presence of carrageenanmaltodex. Guar-locust bean-carrageenan led to significant (p < 0.05) highest levels of β-gal activity of L. rhamnosus GGB103 (1287 ± 4.24 Miller units/ mL) compared to the control (78 ± 2.83 Miller units/ mL). L. rhamnosus GG B101and L. rhamnosus GG B103 were the best strains to attain enhanced levels of β-galactosidase activity. This shows that the inclusion of carrageenan-maltodextrin and guar-locust bean-carrageenan in milk could improve growth, viability and achieve an enhanced level of β-galactosidase activity in L. rhamnosus GG B101 and L. rhamnosus GG B103. The information gleaned from this study could be used in the food industry to improve the quality of probiotic functional foods and thereby contribute to the alleviation of lactose malabsorption.

Perception Analytics Of An In-Depth Observational Analysis Of 6th Grade African American Male Students' Personal Agency, Devetta Holman Nash

Dissertations

Existing scholarship on self-concept and its relevance to personal agency in the classroom does not incorporate the lived experiences of African American middle school boys. Today, in the United States, only 10% of 8th grade African American boys can read proficiently (Holzman, 2011). This research study investigates the perceptions of seventeen middle school African American males' classroom experiences to determine factors that contribute to their classroom engagement and personal agency. The study also illustrates that there is a significant need for greater self-identity and self-concept within the learning environment, which allows African American male students to self–actualize their sense of …

The quality of life (QOL) effects of basal-bolus insulin management are not fully known. This cross-sectional, observational study was based on the Revised Wilson and Cleary Model for Health Related Quality of Life, which measures five QOL domains (biological function, symptoms, functional status, general health perceptions, and overall QOL). The study aims were to describe, compare, and predict QOL in persons with T2DM based on type of insulin management (oral meds only, basal insulin only, …

Predicting Emotion Regulation In Early Childhood: The Impact Of Maternal Well-Being, Infant Crying, And Dyadic Mutuality, Tiffany Burkhardt

Dissertations

Learning adaptive emotion regulation skills in early childhood has been identified as fundamental to social competence, academic success, and psychological well-being. Because children learn to regulate their emotions through interactions with their caregivers, dyadic mutuality between the mother and infant may influence child emotion regulation capacity more than maternal behavior alone. To better understand the impact of maternal well-being and infant crying on the development of emotion regulation, parenting stress, maternal self-efficacy, maternal depression, and infant crying were examined with dyadic mutuality in the parent-child interaction to predict emotion regulation capacity.

The Limits Of Rationality: Suicidality, Affectivity, And The Rational, Maria Jennifer Kulp

Dissertations

In this project, I expose conceptual and moral difficulties with the concept of rational suicide. After offering a comprehensive list of criteria used to define rationality in the bioethics literature, I turn to the scholarship of Susan Sherwin, Susan Wolf, Rosemarie Tong, Lisa Ikemoto and others to apply feminist critiques regarding the privileging of the liberal individual and claims of value neutrality in bioethics generally to the rational suicide literature specifically. Further, using the work of Genevieve Lloyd, I argue that just as definitions of rationality have been used to marginalize vulnerable populations (e.g., women and minorities), a similar marginalization …

Neuroscience And Galen: Body, Selfhood And The Materiality Of Emotions On The Early Modern Stage, Devon Wallace

Dissertations

From antiquity until the turn of the nineteenth century, temperament, mood and personality were believed to exist within, be managed by, and interact with material substance. Before the medical revolution of the late seventeenth century, early modern theories of anatomy and medicine were primarily based on the writings of Galen, who lived in the second century but was him influenced by a much older medical and philosophical tradition. In this period, the playwrights raise the same central question that now appears in so many reactions to the increasingly accepted "neurocentric" world view: "to what extent do I have an emotional …

Quantifying Value In Public Health: Using Economic Methods To Analyze System Change, Theresa M. Green

Dissertations

In this time of economic downturn, it is becoming increasingly important for organizations, including those in public health, to “prove their worth,” to show the value in improvement strategies. Health agencies have learned to discuss impact in terms of health outcome and mortality/morbidity measures. However, it is critical that these impacts are also expressed in a way that shows cost-efficiency and economic benefit especially for promising, evidence-based public health interventions. Although several methods of economic evaluation including cost-effective analysis, cost-utility analysis, or cost-benefit analysis and return on investment (ROI) have been used in social sciences and health research, fewer examples …

The Impact Of A Dance Aerobics Program On Middle School Girls' Physical Activity Level, Self-Efficacy, And Decisional Balance, Alexis Suozzi Bridley

Dissertations

Rates of childhood obesity have increased dramatically in recent years. Decrease in physical activity is among the leading causes, with adolescent females at greatest risk for obesity. School-based interventions have shown promise; however, few studies have considered the type of activity on physical activity level. According to the Transtheoretical Model (TTM), intrinsic readiness, self-efficacy, and perceived risks and benefits regarding change contribute to behavior change. Yet no known studies have considered the impact of intervention with a traditionally preferred activity on selfefficacy and decisional balance. Therefore, this study aimed to explore the impact of a 2- week dance aerobics program …

Dynamics Of Perceptual Organization In Complex Visual Search: The Identification Of Self Organized Criticality With Respect To Visual Grouping Principles, Attila Jozsef Farkas

Dissertations

The current project applies modern quantitative theories of visual perception to examine the effect of the Gestalt Law of proximity on visual cognition. Gestalt Laws are spontaneous dynamic processes (Brunswik & Kamiya, 1953; Wertheimer, 1938) that underlie the principles of perceptual organization. These principles serve as mental short-cuts, heuristic rule-of-thumb strategies that shorten decision-making time and allow continuous, efficient processing and flow of information (Hertwig & Todd, 2002). The proximity heuristic refers to the observation that objects near each other in the visual field tend to be grouped together by the perceptual system (Smith-Gratto & Fisher, 1999). Proximity can be …
