The reduced bio-degradation in the SB microcosms may have resulted from the ~40% higher carbon content in the SB microcosms, which would be expected to increase the soil-water distribution coefficient by a comparable amount. Reduced TCS concentration in soil pore water would be expected to slow bio-transformation, potentially in a nonlinear fashion. Another possible contributor to …

Several authors have also examined the impact of macroeconomic shocks on investment in schooling
In this chapter I have presented an attempt to estimate the effect of rural out-migration on rural wages. I find a strong positive and robust effect of rural out-migration on rural wages in Brazil during the period 1991-2000. Using a cohort analysis my results suggest that rural out-migration flows between 1991 and 2000 have increased …
Vegetable production is also an important part of Fresno County agriculture
From 2000 and 2015, the organic production of spring mix lettuce increased 153% in Monterey County. Short-term lettuce data in the County reflect this trend. Since the passage of the 2012 Ag Waiver , organic head lettuce production has increased 155%, from 112 acres to 174 acres, organic romaine lettuce has increased by roughly the …

A related distributive conflict concerns communities disproportionately affected by a given policy
The bio-assessment studies show a clear relationship between increased water pollution and increased agricultural and urban land use . Nationwide, agricultural non-point pollution is the chief impediment to achieving national water quality objectives . The EPA lists the chief components of these non-point source agricultural pollutants as nitrogen and phosphorus from fertilizers, pesticides, animal sources, soil erosion, …
Any discharger that could affect water quality must obtain a permit to pollute
Exclusion discourse placed Chinese as more efficient than whites, whose “manhood” is wasted in repetitive tasks such as mining and service work. Lye shows that the Chinese were for this reason seen as more “modern,” more suited to a future of proletarian work. The Anglo-Saxon’s supposedly large, violent, inefficient body had been well adapted to …

The mysterious decline of Chinese rice provides the possibility for the rise of American Wheat
Our results suggest that the yield effects of crop rotational histories in cotton are relatively modest in magnitude: the posterior means for effects of any specific crop were mostly under 15%. However, given the tight profit margins of commercial agriculture, a 15% change in yield could translate into a far greater percentage change in profit, …
Studies have shown that people consume less water at higher prices
The Southern California Comprehensive Water Reclamation and Reuse Study , for example, provides a comprehensive assessment of existing reuse and reuse potential in Southern California.The following is a review of key moments in history that changed water policy, from passage of water rights legislation to the voter approval of the State Water Project . Although …

Higher real rates cause the demand for primary goods to fall
Accordingly, foreign monetary authorities will underestimate their own money demands, and their policy will turn out to be more restrictive than desired. Foreign monetary independence from U. S. policies is lost. A second possibility is that foreign authorities recognize unanticipated shifts in U. S. monetary policy quickly. They may act to maintain the value of …

This paper begins with a review of regional impacts of climate change to California agriculture
Prior to Smith and Mendelsohn , several notable studies examined the state of the knowledge of climate assessments at the US level . In particular, Lewandrowski and Schimmelpfennig integrate the knowledge from both programming and econometric studies of the agricultural sector. Other reviews have focused on the technical details of the different modeling approaches without discussing …
This may be due to the deviation of linearity of the %AB and F530 metric at high biomass
Sobal sensitivity analysis utilizing polynomial regression like- wise determined FBS, MgSO4, and L-Phenylalanine were the most explanatory components when taking component-component interactions into account. Focusing on optimizing only those components might bring further improvements, which is now feasible because fewer experiments were needed to arrive at this conclusion. Another issue was that the HND algorithm …
