The Effect of Glycemic Index and Glycemic Load on Glucose Control, Lipid Profiles and Anthropometrics Among Low-Income Latinos With Type 2 Diabetes: A Dissertation

Background The incidence of type 2 diabetes has increased dramatically, particularly among Latinos. While several studies suggest the beneficial effect of lowering glycemic index and glycemic load in patients with type 2 diabetes, no data exists regarding this issue in the Latino population. The purpose of this study was to determine the effect of lowering glycemic index and glycemic load on diabetes control, lipid profiles and anthropometrics among Latinos with type 2 diabetes. Methods Subjects participated in a 12 month randomized clinical trial. The intervention targeted diabetes knowledge, attitudes and behavioral capabilities related to diabetes self management with content including nutrition and physical activity. The nutrition protocol emphasized reduction in glycemic index, fat, salt and portion size and increase in fiber. The control group was given usual care. Measurements included Hba1c, fasting glucose, total cholesterol (TC), low density lipoproteins (LDL) and high density lipoproteins (HDL), HDL:LDL ratio, TC:HDL ratio, waist circumference and BMI and were collected at baseline, 4 and 12-months. Results Two hundred fifty two Latino adults with type 2 diabetes participated in the study. Baseline mean HbA1C was 8.98% (SD=1.87), BMI was 34.76 kg/cm (SD=6.94), age was 56 (SD=11.18) years and 76% were female. Reduction in glycemic index was positively associated with a reduction in logHbA1c (p=0.006), HDL:LDL ratio (p=0.037) and waist circumference (p=0.003) overtime, but not with fasting glucose, TC, LDL and HDL, TC:HDL ratio, body weight or BMI. No significant associations were found between glycemic load and any measures. Conclusion Results suggest that lowering glycemic index may have a positive effect on some markers of diabetes control, lipid profiles and anthropometrics among Latinos with type 2 diabetes, but not others. While statistically significant reductions in GI and GL were noted, the actual reduction was small. Thus, greater reduction in GI and GL may be needed for clinical significance and greater effect on metabolic outcomes. Future research should target populations with higher baseline GI and GL

Slot error rate performance of DH-PIM with symbol retransmission for optical wireless links

In this paper we introduce the dual-header pulse interval modulation (DH-PIM) technique employing a simple retransmission coupled with a majority decision detection scheme at the receiver. We analytically investigate the slot error rate (SER) performance and compare results with simulated data for the symbol retransmissions rates of three, four and five, showing a good agreement. We demonstrate that the proposed scheme significantly reduces the SER compared with the standard single symbol transmission system, with retransmission rate of five offering the highest code gain of 5 dB

Functional Regression Methods for Densely-Sampled Biomarkers in the ICU

This thesis develops methods for modeling longitudinal predictors by treating them as functional covariates in regression models. First, I introduce Variable-Domain Functional Regression, which extends the generalized functional linear model by allowing for functional covariates that have subject-specific domain widths. I then propose a blueprint for the inclusion of baseline functional predictors in Cox proportional hazards models. Finally, I propose the Historical Cox Model, which introduces a new way of modeling time-varying covariates in survival models by including them as historical functional terms. Methods were motivated by and applied to a study of association between daily measures of the Intensive Care Unit (ICU) Sequential Organ Failure Assessment (SOFA) score and mortality, and are generally applicable to a large number of new studies that record a continuous variables over time

PENGARUH PERSEPSI KUALITAS, KEPUASAN PELANGGAN DAN LOYALITAS MEREK TERHADAP LOYALITAS PELANGGAN MOBIL MPV TOYOTA KIJANG INNOVA DI SURABAYA

This research is about the effect of perceived quality, customer satisfaction and brand loyalty of the users of MPV Toyota Kijang Innova in Surabaya toward their loyallty. The rasional of conducting this research is that Toyota Kijang Innova’s brand index has dropped over the last four years. The study is a causal research because it was aimed at measuring the effect of independent variabel toward dependent variabels. The design of this study was that this study used the users of Toyota Kijang Innova as the respondents since this study needed primary data gathered by disseminating questionnaire to the respondents. This research used judgement sampling with 120 respondents. Data were collected using a questionnaire. The analysis method used Structural Equation Model using AMOS program version 18,0. The results showed that only two hypotheses accepted as significantly affecting, namely are that first, the perceived quality significantly affects the satisfaction of Toyota Kijang Innova users, Second, the perceived quality significantly affects the brand loyalty of the Toyota Kijang Innova users,anyhow the satisfaction of the Toyota Kijang Innova users do not significantly affect the loyalty of Toyota Kijang Innova users. Countering the results of this study, Toyota Kijang Innova should be unsure of some aspects referring to the benefits of its competitor’s car.

Lucretius' De rerum natura and satire

This dissertation provides the first extended, systematic analysis of De Rerum Natura (DRN)'s engagement with the Graeco-Roman satiric traditions and argues that DRN plays an important part in the development of the Roman genre of satire. Chapter 1 treats key preliminaries to the topic: the prior scholarship on satire in DRN, the typology of ancient didactic, the poem's contexts (literary, philosophical, intellectual), the distinction between the mode of satire and the genre of satire, and methodology. Chapter 2's first half develops a portrait of the satirist-figure in Graeco-Roman literature, in a synthesis of satiric poetry (works that employ the broader mode of satire, as opposed to works of the actual Roman genre of satire) and current scholarship on the topic: the satirist employs a personal voice of comic mockery from a self-contradictory position of moral superiority and social abjection. Chapter 2's second half evaluates how DRN's speaker takes on the role of satirist both in familiar diatribal or invective passages (against the Presocratics in book 1, the fear of death in 3, love in 4) and in other passages less often connected with satire and comic mockery. Chapter 3 focuses on other features of DRN's engagement with the satiric mode, particularly the formal characteristics of satire and the tensions between satire and didactic in both satiric literature and DRN--which, as both chapters show, deserves inclusion in the category of satiric literature. Chapter 4 turns to the Roman genre of satire. After examination of ancient definitions of the genre, the term satura, and the programmatic statements by later satirists about Lucilius, the chapter considers the thematic, stylistic, generic, and poetic connections between DRN and earlier Roman satire--not only Lucilius but also Ennius' Saturae. Chapter 5 argues that DRN takes advantage of generic tropes in Roman satire; that Lucretius' poem influences how the later satirists Horace, Persius, and Juvenal use such tropes; and that these satirists allude prominently to DRN. The chapter also argues that the ends of DRN books 2-6 are satires on Roman civic life. A general conclusion speculates on implications of the dissertation's line of inquiry

Luminosity distance in Swiss cheese cosmology with randomized voids. II. Magnification probability distributions

We study the fluctuations in luminosity distances due to gravitational lensing by large scale (> 35 Mpc) structures, specifically voids and sheets. We use a simplified "Swiss cheese" model consisting of a \Lambda -CDM Friedman-Robertson-Walker background in which a number of randomly distributed non-overlapping spherical regions are replaced by mass compensating comoving voids, each with a uniform density interior and a thin shell of matter on the surface. We compute the distribution of magnitude shifts using a variant of the method of Holz & Wald (1998), which includes the effect of lensing shear. The standard deviation of this distribution is ~ 0.027 magnitudes and the mean is ~ 0.003 magnitudes for voids of radius 35 Mpc, sources at redshift z_s=1.0, with the voids chosen so that 90% of the mass is on the shell today. The standard deviation varies from 0.005 to 0.06 magnitudes as we vary the void size, source redshift, and fraction of mass on the shells today. If the shell walls are given a finite thickness of ~ 1 Mpc, the standard deviation is reduced to ~ 0.013 magnitudes. This standard deviation due to voids is a factor ~ 3 smaller than that due to galaxy scale structures. We summarize our results in terms of a fitting formula that is accurate to ~ 20%, and also build a simplified analytic model that reproduces our results to within ~ 30%. Our model also allows us to explore the domain of validity of weak lensing theory for voids. We find that for 35 Mpc voids, corrections to the dispersion due to lens-lens coupling are of order ~ 4%, and corrections to due shear are ~ 3%. Finally, we estimate the bias due to source-lens clustering in our model to be negligible
