information technology production process outsourcing and Manufacturing Plant performance
Social Science Research Network, 2006Co-Authors: Indranil R Bardhan, Jonathan Whitaker, Sunil MithasAbstract:What is the role of information technology (IT) in enabling the outsourcing of Manufacturing Plant production processes? Do Plant strategies influence production outsourcing? Does production process outsourcing influence Plant performance? This research addresses these questions by investigating the role of IT and Plant strategies as antecedents of production outsourcing, and evaluating the impact of production outsourcing and IT investments on Plant cost and quality. We develop a theoretical framework for the antecedents and outcomes of production outsourcing at the Plant level. We validate this theoretical framework using cross-sectional survey data from U.S. Manufacturing Plants. Our analyses suggests that Plants with greater IT investments are more likely to outsource their production processes, and that IT spending and production outsourcing are associated with lower Plant cost of goods sold and higher product quality improvement. Our research provides an integrated model for studying the effect of IT and production outsourcing on Plant performance.

application of zerovalent iron fe0 to enhance degradation of hchs and ddx in soil from a former organochlorine pesticides Manufacturing Plant
Chemosphere, 2010Co-Authors: Sucai Yang, Mei Lei, Tongbin Chen, Qi LiangAbstract:Remediation of pesticide-polluted soil is particularly challenging when pesticides in soil are aged and a mixture of pesticides is present. Application of zerovalent iron (Fe(0)) was investigated to accelerate the degradation of HCHs (alpha-, beta-, gamma- and delta-hexachlorocyclohexane) and DDX (DDT, DDE and DDD) in the soil from a former organochlorine pesticide Manufacturing Plant. Ultrasonic extraction was used extract the organochlorine pesticides from soil. The identification and quantification of organochlorine pesticides in the extracts were accomplished by gas chromatograph. The addition of Fe(0) facilitated the degradation of the beta-HCH isomer, but had little effect on the degradation of alpha-HCH, gamma-HCH and delta-HCH. Zerovalent iron significantly increased the degradation of p,p'-DDT and o,p'-DDT in soil, and the percentage degradation of p,p'-DDT and o,p'-DDT increased with increased Fe(0) concentration during the first period of incubation. However, the amount of p,p'-DDD, the main dechlorinated product of p,p'-DDT, basically kept increased except in the unamended soil. The addition of Fe(0) therefore did not increased the percent degradation of summation SigmaDDT (p,p'-DDT+p,p'-DDD+p,p'-DDE) markedly.

polychlorinated biphenyl exposure diabetes and endogenous hormones a cross sectional study in men previously employed at a capacitor Manufacturing Plant
Environmental Health, 2012Co-Authors: Victoria Persky, Julie Piorkowski, Mary Turyk, Sally Freels, Robert T Chatterton, John Dimos, Leon H Bradlow, Lin Kaatz Chary, Virlyn Burse, Terry G UntermanAbstract:Studies have shown associations of diabetes and endogenous hormones with exposure to a wide variety of organochlorines. We have previously reported positive associations of polychlorinated biphenyls (PCBs) and inverse associations of selected steroid hormones with diabetes in postmenopausal women previously employed in a capacitor Manufacturing Plant. This paper examines associations of PCBs with diabetes and endogenous hormones in 63 men previously employed at the same Plant who in 1996 underwent surveys of their exposure and medical history and collection of bloods and urine for measurements of PCBs, lipids, liver function, hematologic markers and endogenous hormones. PCB exposure was positively associated with diabetes and age and inversely associated with thyroid stimulating hormone and triiodothyronine-uptake. History of diabetes was significantly related to total PCBs and all PCB functional groupings, but not to quarters worked and job score, after control for potential confounders. None of the exposures were related to insulin resistance (HOMA-IR) in non-diabetic men. Associations of PCBs with specific endogenous hormones differ in some respects from previous findings in postmenopausal women employed at the capacitor Plant. Results from this study, however, do confirm previous reports relating PCB exposure to diabetes and suggest that these associations are not mediated by measured endogenous hormones.

associations of polychlorinated biphenyl exposure and endogenous hormones with diabetes in post menopausal women previously employed at a capacitor Manufacturing Plant
Environmental Research, 2011Co-Authors: Victoria Persky, Julie Piorkowski, Mary Turyk, Sally Freels, Robert T Chatterton, John Dimos, Leon H Bradlow, Lin Kaatz Chary, Virlyn Burse, Terry G UntermanAbstract:There is an increasing body of literature showing associations of organochlorine exposure with risk of diabetes and insulin resistance. Some studies suggest that associations differ by gender and that diabetes risk, in turn, may be affected by endogenous steroid hormones. This report examines the relationships of serum PCBs and endogenous hormones with history of diabetes in a cohort of persons previously employed at a capacitor Manufacturing Plant. A total of 118 women were post-menopausal with complete data, of whom 93 were not using steroid hormones in 1996, at the time of examination, which included a survey of exposure and medical history, height, weight and collection of blood and urine for measurements of lipids, liver function, hematologic markers and endogenous hormones. This analysis examines relationships of serum polychlorinated biphenyls (PCBs), work exposure and endogenous hormones with self-reported history of diabetes after control for potential confounders. All PCB exposure groups were significantly related to history of diabetes, but not to insulin resistance as measured by the homeostatic model assessment of insulin resistance (HOMA-IR) in non-diabetics. Diabetes was also independently and inversely associated with follicle stimulating hormone (FSH), dehydroepiandrosterone sulfate (DHEAS) and triiodothyronine (T3) uptake. HOMA-IR was positively associated with body mass index (BMI) and C-reactive protein (CRP) and inversely associated with sex hormone binding globulin (SHBG) and T3 uptake after control for PCB exposure. Possible biologic mechanisms are discussed. This study confirms previous reports relating PCB exposure to diabetes and suggests possible hormonal pathways deserving further exploration.
