“Cause my parents love me” : the effects of Korean immigrants’ parenting on adolescents’ academic and psychological outcomes
Creators: name: Hong, KyongJoo
Publisher: name: The University of Texas at Austin
Year: 2018
Subjects: Korean American
Acculturation
Parental warmth
Psychological adjustment
Mixed method

description: Despite increasing research on Korean immigrants’ parental involvement, little is known about links between immigrant parents’ acculturation and their children’s academic and psychological outcomes through parental academic socialization and their children’s perceptions of parental warmth. In a mixed method design, 104 Korean American mother-child dyads participated in the quantitative part of the study, and 7 of these dyads were interviewed. Using a moderated mediation model, I investigated the conditional nature of parental warmth and children’s acculturation attitudes in the path from the mothers’ acculturation to the children’s academic and psychological outcomes via their mothers’ academic socialization. Direct relationships and strong correlations exist between variables of interest; however, the moderated mediation model was not supported. The qualitative part of the analysis produced a rich description of the process of academic socialization and parent-child interactions in Korean immigrant families. Korean immigrant children did not psychologically suffer from mothers’ emphasis on hard work but perceived it as a sign of parental love for them. Thus, I further investigated mothers’ acculturation effects to determine whether they transmitted to children’s psychological outcomes—not conditionally but simultaneously through a serial mediation model. This model included mother’s attitude toward Korean culture as the predictor, mother’s academic socialization of emphasis on hard work as the first mediator, maternal warmth as the second mediator, and child’s psychological adjustment issues as the outcome variable. The overall serial mediation model was significant. The mediation model—only with the first mediator—revealed that higher levels of mother’s attitude toward Korean culture significantly increased mother’s emphasis on hard work, and that decreased child’s psychological adjustment issues. However, when the second mediator was included in the model, mother’s attitude toward Korean culture was associated with increased mother’s emphasis on hard work, which was associated with decreased maternal warmth, and that was linked to increased child’s psychological adjustment issues. The current study provides a more dynamic and multidimensional understanding regarding the relationship between parental acculturation and child’s academic and psychological outcomes through parental academic socialization and parental warmth. Implications of these findings and suggestions for future research are discussed.

description: Benefit for mankind is the key for intensive scientific innovation. In this belief, the research in field of biofuels is one such to create an ecofriendly environment. The work presented here includes the study on the influence of variation of compression ratio(CR) on engine performance, combustion and emissions for the selected biodiesel fuels namely Vateria Indica Oil Methyl Ester (VIOME) B20, Waste Cooking Methyl Ester(WCOME) B20 and W10V10 (Hybrid of VIOME B10 and WCOME B10)along with neat diesel. The main focus is on VIOME due to the reason being very little research is done on the same. The compression ratio levels selected are 17, 17.5 and 18 where 17.5 is standard for the engine design to work on diesel. The increase of the compression ratio favored to increase the brake thermal efficiency (BTE) and reduction in brake Specific fuel consumption (BSFC). The combustion characteristics enhanced at CR 18 due to the temperature assistance. The emissions did not show a significant improvement. The NOx levels were observed to be high whereas the CO levels dropped due to the better combustion.

Subjects: subject: Hematopoietic agents
subject: Pernicious anemia

description: One of the necessary fundamental approaches to an understanding of malignant growth is the study of normal growth - the orderly proliferation and differentiation of cells. After we had considered a number of possible studies which might be undertaken the objectives of which were thought to contribute to an understanding of cancer, it was decided to undertake investigation of some of the chemical agents and biochemical processes incident to the pathological behavior of the bone marrow in pernicious anemia. In pernicious anemia the bone marrow resembles in many respects malignant tumors; the amount of tissue increases but it becomes functionally inefficient. The bone marrow cells which would normally develop into the red blood cells multiply at an exaggerated rate but remain in a primitive form and never mature. The conversion of the tissue from this pathological condition to a normal state had been shown to be effected by any one of several specific substances, (a) an erythrocyte maturation factor, (b) an incubation mixture of an "extrinsic factor" and the "intrinsic factor", (c) folic acid and (d) thymine. These materials, then, are intimately involved in establishing the conditions necessary for the normal functioning of at least one type of tissue. Consequently, an extensive and comprehensive research of the literature was made in order to collect together and correlate the known physiological and chemical aspects of pernicious anemia (and morphologically related disorders, (with the chemical agents and biological factors which had been shown to be involved. A summary of this literature research constitutes the first section of this thesis. During the assembling of this material there became evident a number of interesting hypotheses which might explain some of the isolated observations which had been reported. Several of these hypotheses were tested for their validity and the summary of this experimental work constitutes the second portion of this dissertation

description: This study aims to elucidate the exposure properties of nanoparticles (NPs; <100 nm in diameter) in semiconductor manufacturing processes. The measurements of airborne NPs were mainly performed around process equipment during fabrication processes and during maintenance. The number concentrations of NPs were measured using a water-based condensation particle counter having a size range of 10–3,000 nm. The chemical composition, size, and shape of NPs were determined by scanning electron microscopy and transmission electron microscopy techniques equipped with energy dispersive spectroscopy.The resulting concentrations of NPs ranged from 0.00–11.47 particles/cm3. The concentration of NPs measured during maintenance showed a tendency to increase, albeit incrementally, compared to that measured during normal conditions (under typical process conditions without maintenance). However, the increment was small. When comparing the mean number concentration and standard deviation (n ± σ) of NPs, the chemical mechanical polishing (CMP) process was the highest (3.45 ± 3.65 particles/cm3), and the dry etch (ETCH) process was the lowest (0.11 ± 0.22 particles/cm3). The major NPs observed were silica (SiO2) and titania (TiO2) particles, which were mainly spherical agglomerates ranging in size from 25–280 nm. Sampling of semiconductor processes in CMP, chemical vapor deposition, and ETCH reveled NPs were <100 nm in those areas. On the other hand, particle size exceeded 100 nm in diffusion, metallization, ion implantation, and wet cleaning/etching process. The results show that the SiO2 and TiO2 are the major NPs present in semiconductor cleanroom environments.

The advantage of this method is short reaction time with excellent yield and safety, inexpensive cost, and use of easily recyclable nanocatalytic material. Higher activity of sulfated titania over TiO2 is found to be due to its increased Brønsted acidity.

description: The Smoke Aerosol Measurement Experiment (SAME) has been conducted twice by the National Aeronautics and Space Administration and provided real-time aerosol data in a spacecraft micro-gravity environment. Flight experiment results have been recently analyzed with respect to comparable ground-based experiments. The ground tests included an electrical mobility analyzer as a reference instrument for measuring particle size distributions of the smoke produced from overheating five common spacecraft materials. Repeatable sample surface temperatures were obtained with the SAME ground-based hardware, and measurements were taken with the aerosol instruments returned from the International Space Station comprising two commercial smoke detectors, three aerosol instruments, which measure moments of the particle size distribution, and a thermal precipitator for collecting smoke particles for transmission electron microscopy (TEM). Moment averages from the particle number concentration (zeroth moment), the diameter concentration (first moment), and the mass concentration (third moment) allowed calculation of the count mean diameter and the diameter of average mass of smoke particles. Additional size distribution information, including geometric mean diameter and geometric standard deviations, can be calculated if the particle size distribution is assumed to be lognormal. Both unaged and aged smoke particle size distributions from ground experiments were analyzed to determine the validity of the lognormal assumption. Comparisons are made between flight experiment particle size distribution statistics generated by moment calculations and microscopy particle size distributions (using projected area equivalent diameter) from TEM grids, which have been returned to the Earth.Copyright 2015 American Association for Aerosol Research

description: Fully autonomous vehicles provide an opportunity to improve current transportation solutions; both for drivers and for people unable to drive. In this paper we present the preliminary results of a study aiming to understand user needs and expectations for autonomous vehicle interfaces. We found that users expect a different type of information to be fed back to them depending on whether the vehicles are privately owned or shared. The results of this study will be confirmed by further work and contribute to the development of a baseline fully autonomous vehicle user interface.

description: Bacteria, viruses, fungus, and other biological components (toxins, membranes, spores) can spread in the air through various aerosolization processes (breathing, bubbling, explosion, evaporation) and travel until they reach a surface or a host. Nosocomial diseases are an example of illnesses caused by a human contact with such pathogen vectors in hospital settings. Very little is known about the aerosolization processes of viruses and bacteria and their potential to infect people after their passage in the airborne state and about the microbial burden carried by individual aerosol particles. Here we propose a novel approach to study the aerosolization mechanisms of bacteria in single particles using fluorescence spectroscopy and a homemade system allowing the control of the aerosolization and the impaction of bacteria on a black filter. We validated the concept using P. fluorescence and E. coli. The results show that independently of the amount of P. fluorescens and E. coli aerosolized the average distribution of cells impacted on a black filter is described by a Poisson fit with λ ∼ 0.6 ± 0.2. This means that using this aerosolization process, an aerosol will present no bacterium, but when it does, the number of bacteria per particle in the distributions will more probably be one. We also observed that the aerosolization processes of these two bacterial species allow P. fluorescens to be preferentially aerosolized against E. coli. These results demonstrate that fluorescence spectroscopy is a powerful tool to study bioaerosols in single particles. This technique can be used to study several phenomena like preferential aerosolization.Copyright 2015 American Association for Aerosol Research

description: In this article, we study the non parametric estimation of some regression curves when the data are observed with additive distortions, and these distortions for unobservable response variables and covariates are connected with a common observed confounding variable. We study the estimates of the non parametric mean function and its first derivative, the variance function, the Sharpe ratio function, and the correlation curve function. We obtain asymptotic normality results for the proposed non parametric estimators. Monte Carlo simulation experiments are conducted to examine the performance of the proposed estimators. The proposed estimators are applied to analyze a QSAR fish toxicity dataset for illustration.

description: We propose a covariance ratio measure for symmetry or asymmetry of a probability density function. This measure is constructed by the ratio of the covariance connected with the density function and the distribution function. We first propose a non parametric moment-based estimator of the covariance ratio measure and study its asymptotic results. Next, we consider statistical inference of the covariance ratio measure by using the empirical likelihood method. The empirical likelihood statistic is shown to be asymptotically a standard chi-squared distribution. Last, we study the covariance ratio measure when the random variable is unobserved under the multiplicative distortion measurement errors setting. The density function and the distribution function of the unobserved variable are estimated by using four calibrated variables. Appealing to these estimators, the calibrated covariance ratio measures are proposed and further shown to be asymptotically efficient as if there are no multiplicative distortion effects. We conduct Monte Carlo simulation experiments to examine the performance of the proposed estimators and test procedures. These methods are applied to analyze two real datasets for illustration.

The synthesized silver nanoparticles were characterized using UV-Vis spectroscopy, infrared spectroscopy, powder X-ray diffraction, and transmission electron microscopy. The predominantly spherical monodispersed 2–10 nm sized silver nanoparticles were obtained for the first time using lemon extract. The antimicrobial activity of silver nanoparticles was also explored. Lemon extract–mediated synthesis is cost efficient, eco-friendly and an easy alternative to conventional methods of silver nanoparticles synthesis.

The predominantly spherical mono dispersed 2 to 10 nm sized silver nanoparticles were obtained for the first time using lemon extract. The anti-microbial activity of silver nanoparticles was also explored. Lemon extract-mediated synthesis is cost efficient, eco-friendly and an easy alternative to conventional methods of silver nanoparticles synthesis.

description: A new three-dimensional neodymium(III)-containing coordination polymer, [Nd2(μ2-ox)(μ4-PDC)2(H2O)4]•2H2O (1) (H2PDC = pyridine-3,5-dicarboxylic acid, H2ox = oxalate acid), has been successfully synthesized under hydrothermal conditions via mixed-ligand of pyridine-3,5-dicarboxylate and in situ generated oxalate, and characterized by elemental analysis, IR, and single-crystal X-ray diffraction. The crystal structural analysis reveals that complex 1 displays an unusual three-dimensional framework with a pillared-layer containing a two-dimensional metal-organic layer architecture, and possesses a rare bimodal (4,5)-connected net with (44.62)(44.64.82) topology. Moreover, complex 1 exhibits intense fluorescent emission at room temperature in the solid state.

description: Смоделирована работа серийных пропитанных арамидных кордных нитей Аром-175, Русар-200 и синтетических канатов марок КС-4,5, КС-4,5Пл при их длительной эксплуатации в каркасе резинотехнического изделия. Суть моделирования заключается в следующем: на специально сконструированных устройствах, имитирующих работу данных материалов в силовом каркасе патрубков, определено изменение состояния надмолекулярной структуры и физико-механических показателей кордных нитей и синтетических канатов в процессе циклических и статических испытаний. Показано, что циклическая прочность пропитанных серийными растворами кордных нитей Аром175, Русар-200 и синтетических канатов значительно превышает нормативное значение для патрубков. Отмечено преимущество при эксплуатации синтетического каната КС-4,5Пл с плетеным сердечником по сравнению с сердечником в виде жгута КС-4,5. Моделирование работы арамидных материалов в изделии показало, что при их эксплуатации будет происходить уменьшение разрывной нагрузки и гибкости цепи полимера в изделиях с синтетическими канатами и кордными тканями, пропитанными раствором Р-138-12. Свойства кордных нитей, пропитанных раствором Р-147с12, в процессе эксплуатации не ухудшаются. Практическая ценность исследования — прогнозирование эксплуатационных свойств резинотехнических изделий с арамидным каркасом.

description: Focuses on the tool integration perspective in software development in order to address the application of traditional tool integration mechanisms as well as new integration mechanisms based on the World Wide Web and Java. Our process-centred Web-based teamwork support environment is used as a case study to illustrate the potential power for tool integration. Research into process-centred teamwork has been intensively carried out in communities such as software and business engineering, computer-supported cooperative work and information systems for more than a decade. However, given the exposure of the Web and Java, a significant impact has formed to computer-mediated teamwork so that it can be beneficial to most people, including both computing and non-computing professionals. This paper pays special attention to the tool integration mechanisms used in our Web-based teamwork development environment prototyped in Java, with respect to the access to Web data and integration with applications.

description: Determination of the elemental composition of cosmetic products for quality control and impurity analysis has traditionally been performed using plasma spectroscopic techniques that feature time-consuming, hazardous, and completely destructive sample preparation steps. Wavelength dispersive X-ray fluorescence spectroscopy (WDXRF) allows for quantitative and qualitative analysis of the elemental composition of materials for a range of elemental masses with less extensive sample preparation and higher sample throughput. WDXRF analysis requires that samples be of uniform thickness and prepared reproducibly. The analysis of products with a high organic solvent content, such as nail polish, by WDXRF has not previously been successful due to sample preparation reproducibility challenges. The goal of this investigation was to develop a method for reproducible preparation of nail polish samples using a thin film applicator. Samples were quantitatively analyzed for fluorine, sodium, magnesium, aluminum, silicon, phosphates, sulfates, chloride, potassium, calcium, titanium, vanadium, manganese, and iron to demonstrate the application of this sample preparation technique to a wide range of elemental masses. The developed preparation method was used to produce replicate thin films with a high degree of reproducibility. Further, the quantitative results obtained using WDXRF exhibit strong agreement with those obtained using inductively coupled plasma optical emission spectroscopy (ICP-OES), demonstrating consistency between independent analytical techniques.
