In this paper, we suggest that ine±ciency may be an indirect, onthe-job compensation to agents in an organization. We show how to use actual production data to reveal the trade-o®s between di®erent ine±ciencies (slacks). Moreover, we discuss how to use this to improve decision making and incentive provisions in organizations.

Reaction kinetics of benzid ine oxidation with ClO 2 in the wastewater was investigated systematically by detecting concentrations of benzid ine with HPLC at regular intervals. The results show that the reaction was firstorder with respect to both ClO2 and benzid ine, and the entire reaction was of second-order. Under condition of pH 6.5 and water temperature 298K, the second-order reaction rat...

Elevated circulating homocyst(e)ine is a risk factor for occlusive vascular disease. We explored whether elevated plasma homocyst(e)ine is associated with increased plasma lipid hydroperoxides that might trigger vascular disease. We obtained plasma containing high levels of homocyst(e)ine from four patients with a homozygous deficiency of cystathionine beta-synthase activity and also from four ...

Previous studies have identified moderately elevated plasma concentrations of homocyst(e)ine as an independent risk factor for coronary heart disease (CHD). The atherogenicity of homocyst(e)ine has mostly been attributed to its effects on endothelial cells, platelets, and the hemostatic system. In this case-control study of 199 male CHD patients and 156 age-matched control subjects, we analyzed...

OBJECTIVE To assess the risk of ischaemic stroke associated with total serum homocyst(e)ine (tHcy) concentration. DESIGN Cohort study. SETTING Caerphilly, South Wales PARTICIPANTS 2254 men age 50 to 64 years recruited between 1984 and 1988. RESULTS 107 men developed ischaemic stroke and mean follow up time was 10.2 years. There was no significant difference in mean serum total homocyst(...

Five 9- or 12-d chick growth bioassays were done in batteries using 2 Met-deficient diets: a purified AA-based diet containing (by analysis, as-fed) 20.3% CP, 0.12% Met, and 0.05% cyst(e)ine; and an AA-fortified corn-peanut meal diet containing (by analysis, as-fed) 19.0% CP, 0.22% Met, and 0.23% cyst(e) ine. Feed-grade DL-Met (dl-M; 99%) was compared with feed-grade DL-OH-Met, Ca (OH-M; 84%). ...

The development of atherosclerotic changes and thromboembolism are common features in homocystinurics. Hence, we postulate a positive correlation between the level of homocyst(e)ine in the blood and the occurrence of coronary artery disease. Homocysteine is found either as free homocystine, cysteine-homocysteine mixed disulfide, or protein-bound homocyst(e)ine. In nonhomocystinuric subjects, mo...

We established the cutoff value for plasma folic acid, using plasma homocyst(e)ine as the functional marker. To do this, we investigated the relationship of the plasma folic acid of 103 apparently healthy adults with their fasting plasma homocyst(e)ine and with their plasma homocyst(e)ine 6 h after oral methionine challenge (100 mg/kg). We also studied the relationship of their plasma folic aci...

BACKGROUND AND PURPOSE Elevated plasma homocyst(e)ine may be a causal and modifiable risk factor for ischemic stroke, but the results of previous studies have been conflicting. One possible explanation is that homocyst(e)ine may only be associated with certain pathophysiological subtypes of ischemic stroke. METHODS We conducted a case-control study of 219 hospital cases with a first-ever isch...
