Developmental trajectories of behavior problems of youth involved in child welfare: influence of caregiver and peer relationships
No full textThis dissertation examined the developmental trajectories of adolescent youth involved with the child welfare system, particularly focusing on their externalizing and internalizing behavioral problems. The study investigated how adolescents’ relationships with caregivers and peers change over time and how they affect these behavioral outcomes. The study also explored whether removing youth from their biological family predicted distinct trajectories of behavior functioning compared to those who remained at home. Data are from the National Survey of Child and Adolescent Well-being (NSCAW), a national probability sample of children and adolescents who have contact with child protective services. Two types of structural equation modeling (SEM), latent growth curve modeling and cross-lagged designs were conducted using M-Plus. All analyses were conducted with sample weights.
Youths reported significantly decreasing internalizing behavior problems over the study period of 36 months. On the other hand, externalizing problems remained considerably stable over time. In order to investigate if youth had different development trajectories depending on whether they stayed at home or were placed in out-of-home care, the sample was divided into four placement groups, i.e., out-of-home youth, in-home youth, the initial out-of-home youth (those who returned home later), and the initial in-home youth (those who were removed from home later). When group differences were investigated, youths did not show significant differences in the initial levels and rates of change of internalizing or externalizing problems over time. In addition, relationships with caregivers and peers were found to be comparable across four groups. Caregiver and peer relationships were significantly related to youths’ internalizing and externalizing problems at baseline as well as over time. When temporal causal relations among caregiver relationships, peer relationships, and behavior problems were investigated, externalizing problems of youth at 18 months were found to affect their caregiver and peer relationships at 36 months.Ph.D.Includes bibliographical references (p. 100-113)by Inseon Le

Enhanced stability and reusability of marine epoxide hydrolase using ship-in-a-bottle approach with magnetically-separable mesoporous silica
No full textWe developed magnetically-separable and highly-stable biocatalyst system of Mugil cephalus epoxide hydrolase (McEH) for enantioselective hydrolysis of racemic epoxides. McEH protein was adsorbed and cross-linked into mesoporous silica with bottle-neck mesopores, which effectively prevented the leaching of cross-linked McEH in a larger mesocellular pores. This ship-in-a-bottle approach allows for highly loaded and stable McEH system. For example, free McEH showed only 7.5% of initial activity under shaking condition at 80 h while ship-in-a-bottled McEH retained 79.5% of initial activity in the same condition. Stable McEH in magnetically-separable mesoporous silica could achieve the yield of 45% for the preparation of enantiopure (S)-styrene oxide with 98%ee. The magnetic nanoparticles pre-incorporated in mesoporous silica enabled an easy recovery of immobilized McEH for repetitive batch resolutions of racemic styrene oxide, allowing for more than 50% of the initial activity was retained after seven recycled uses.

Crosslinked chitosan coating on magnetic mesoporous silica with pre-adsorbed carbonic anhydrase for carbon dioxide conversion
No full textCarbonic anhydrase (CA), an enzyme converting CO2 to bicarbonate, was adsorbed into magnetically-separable spherical mesocellular siliceous foam (Mag-S-MCF). Then, chitosan was adsorbed onto the surface of Mag-S-MCF with pre-adsorbed enzymes, and further crosslinked via the glutaraldehyde treatment. The resulting composite materials, the crosslinked chitosan coating on Mag-S-MCF with pre-adsorbed CA (ADS-CA/CS-GA), could effectively prevent leaching of enzymes, showing no decrease of enzyme activity under shaking (200 rpm) for 85 days. ADS-CA/CS-GA also showed no activity decrease under recycled uses via facile magnetic separation, and could be successfully used for the biocatalytic CO2 conversion to bicarbonate, which was further utilized to generate calcium carbonate in the second batch reactor.

Letter from K.W. Lee to Friends of Michi Weglyn, November 1, 1997
No full textA letter from K. W. (Kyung Won) Lee, an investigative journalist who wrote for the Sacramento Union, to the Friends of Michi Weglyn. Lee wrote that Weglyn was instrumental in the campaign to free Chol Soo Lee, a Korean American man was on death row, but later had his convictions overturned. Lee also wrote that other Japanese American activists were instrumental to the success of this campaign.These materials are from box 73 and 74 of the Frank Chin Papers. The Frank Chin Papers contain personal and professional correspondence between Frank Chin and Michi Weglyn relating to particular projects on which either author was working as well as files related to the Day of Remembrance Tribute to Michi Weglyn
