"Various Mechanisms Across Various Contexts: A Multilevel Analysis of the Immigrant Revitalization Thesis" Paper presented at the annual meeting of the American Society of Criminology – 71st Annual Meeting, Washington Hilton, Washington, DC, Nov 18, 2015 <Not Available>. 2019-12-11 <>

Abstract: Recent research has found a protective effect of immigrant populations on neighborhood crime patterns. The immigrant revitalization thesis explains these findings as a function of a variety of mechanisms that increase social control, economic opportunity, and institutional supports. Yet while some of the mechanisms underpinning this thesis implicitly rely on cultural similarity of immigrant populations, most studies test the thesis using monolithic or pan-ethnic measures that fail to capture the degree of diversity within the local foreign-born population. Using more nuanced measures of the size and diversity of local immigrant populations, this study provides a stricter test of the relative importance of various mechanisms. Based on neighborhoods within a nationally representative sample cities from the National Neighborhood Crime Survey, this research also employs a multilevel approach to test whether and how city context moderates neighborhood-level immigration-crime relationships.

Abstract: This paper makes an important contribution to the social movement literature on differential participation by modeling participation in various forms of activism as a two-stage process: willingness to engage in specific tactics and conversion of this willingness to actual participation. Using a nationally representative sample of Americans, we show that the effect of biographical availability, organizational involvement, and political networks varies not only depending on the stage of the participation process but also depending on the type of the tactic.

"Observed Atrazine and Glyphosate Losses in Agricultural Drainage Water at Various Watershed Scales" Paper presented at the annual meeting of the SOIL AND WATER CONSERVATION SOCIETY, Saddlebrook Resort, Tampa, Florida, Jul 21, 2007 <Not Available>. 2019-12-11 <>
Publication Type: Oral Presentation
Abstract: Off-site herbicide losses represent risks to human and environmental health, as well as a cost to municipalities for removal. Atrazine, widely used in the US for weed control in crops including corn, is detected in many surface waters. Levels are often significantly higher than the 3 µg/L maximum contaminant level (MCL) permitted in drinking water. The advent of glyphosate-tolerant crops brings about a new alternative to atrazine-based weed management. Glyphosate is a nonselective herbicide used in a wide range of engineered glyphosate-tolerant crops, including corn and soybean. Although glyphosate exhibits lower human toxicity than atrazine, as is reflected by its MCL of 700 µg/L, its widespread and potentially continuous use in corn-soybean cropping systems common in the Midwest raises concern. The objectives of this study were to determine extent of agricultural drainage water contamination by atrazine and glyphosate, and how watershed scale impacts observed herbicide levels. Outlet water herbicide levels were monitored from nine watersheds from 300 to 19,000 ha in size, representing sub-basin nestings within three main proximal watersheds in northeast Indiana, for four years. Atrazine concentrations peaked during high-flow events, in some instances reaching 20 to 40 times the MCL. Atrazine levels varied more between years than between watershed sizes. Glyphosate was detected infrequently. During the monitoring period, glyphosate concentration reached 2.5 times the MCL from a 300-ha subwatershed in once high-flow instance less than 48 hours after application. These results indicate that glyphosate has much lower risk to exceed the drinking water standard as compared to atrazine.

Abstract: Great efforts have been made to develop defined and animal-free conditions for culture of human embryonic stem cells (hESCs) to advance these therapeutically promising cells towards clinic. TeSR1 as a defined medium has been shown to support hESC culture as well as hESC derivation. However, the two hESC lines derived in TeSR1 were karyotypically abnormal, probably due to its formula disfavoring derivation of normal hESCs. Indeed, we found that isolated inner cell mass cells often dissociated in TeSR1, failing to develop to any hESC line. In contrast, the traditional undefined hESC medium co-cultured with mouse embryonic fibroblast allowed us to derive two new hESC lines CT1 and CT2. To identify the important factors responsible for the differences, we analyzed hESC lines CT2 and H9 cultured in the defined versus undefined media via global gene expression profiling and differentiation assays. We found that hESCs cultured in the various conditions had dramatically different levels of several essential signaling pathways as well as different preferences in lineage-specific differentiation. Modification of TeSR1 based on these results may help optimize conditions to enhance the derivation efficiency of hESCs and sustain their unbiased differentiation ability.
