IMPACTS OF LARGE SCALE EXPANSION OF BIOFUELS ON GLOBAL POVERTY AND INCOME DISTRIBUTION

This paper analyzes the impact of expansion in biofuels on the global economy, income distribution and poverty. It utilizes simulation results of two World Bank models: a global computable general equilibrium (CGE) model integrated with biofuels, land-use, and climate change modules, and a global income distribution model that utilizes household survey data of 116 countries. The first model simulates the effects over time of large scale expansion of biofuels on resource allocation, output prices, commodity prices, factor prices, and household income of the different countries and regions in the world. The second model uses these results recursively to calculate the impact on global income distribution and poverty. The results from the CGE model indicate that large scale expansion of biofuels lead to higher world prices of sugar, corn, oilseeds, wheat, and other grains, which lead to higher food prices. The increase in food inflation is higher in developing countries than in developed countries. The expansion of biofuels results in higher wages of unskilled rural labor relative to wages of the other labor types which are skilled urban, skilled rural, and unskilled urban, especially in developing countries. These positive wage effects on unskilled rural labor trigger movement of unskilled urban labor towards rural and agriculture. This is because production of feedstock in developing countries is relatively intensive in the use of unskilled rural labor. The effects of large scale expansion of biofuels on poverty vary across regions. But overall there is a slight increase in global poverty. The increase largely comes from South Asia (particularly India) and Sub-Saharan Africa. Significant number of countries in Sub-Saharan Africa show higher poverty with large scale expansion of biofuels. However, poverty declines in East Asia and Latin America regions. Overall, there is a slight increase in the GINI coefficient. There is a slight increase in the GINI coefficient in Sub-Saharan Africa and East Asia. There is a small reduction in the GINI coefficient in the rest of the regions.Agricultural and Food Policy, Environmental Economics and Policy, Food Security and Poverty, International Relations/Trade, Land Economics/Use, Resource /Energy Economics and Policy,

The cholesterol-raising diterpenes from coffee beans increase serum lipid transfer protein activity levels in humans

Cafestol and kahweol–diterpenes present in unfiltered coffee— strongly raise serum VLDL and LDL cholesterol and slightly reduce HDL cholesterol in humans. The mechanism of action is unknown. We determined whether the coffee diterpenes may affect lipoprotein metabolism via effects on lipid transfer proteins and lecithin:cholesterol acyltransferase in a randomized, double-blind cross-over study with 10 healthy male volunteers. Either cafestol (61–64 mg/day) or a mixture of cafestol (60 mg/day) and kahweol (48–54 mg/day) was given for 28 days. Serum activity levels of cholesterylester transfer protein, phospholipid transfer protein and lecithin:cholesterol acyltransferase were measured using exogenous substrate assays. Relative to baseline values, cafestol raised the mean (±S.D.) activity of cholesterylester transfer protein by 18±12% and of phospholipid transfer protein by 21±14% (both P<0.001). Relative to cafestol alone, kahweol had no significant additional effects. Lecithin:cholesterol acyltransferase activity was reduced by 11±12% by cafestol plus kahweol (P=0.02). It is concluded that the effects of coffee diterpenes on plasma lipoproteins may be connected with changes in serum activity levels of lipid transfer proteins

Allelomimesis as universal clustering mechanism for complex adaptive systems

Animal and human clusters are complex adaptive systems and many are organized in cluster sizes $s$ that obey the frequency-distribution $D(s)\propto s^{-\tau}$. Exponent $\tau$ describes the relative abundance of the cluster sizes in a given system. Data analyses have revealed that real-world clusters exhibit a broad spectrum of $\tau$-values, $0.7\textrm{(tuna fish schools)}\leq\tau\leq 2.95\textrm{(galaxies)}$. We show that allelomimesis is a fundamental mechanism for adaptation that accurately explains why a broad spectrum of $\tau$-values is observed in animate, human and inanimate cluster systems. Previous mathematical models could not account for the phenomenon. They are hampered by details and apply only to specific systems such as cities, business firms or gene family sizes. Allelomimesis is the tendency of an individual to imitate the actions of its neighbors and two cluster systems yield different $\tau$ values if their component agents display different allelomimetic tendencies. We demonstrate that allelomimetic adaptation are of three general types: blind copying, information-use copying, and non-copying. Allelomimetic adaptation also points to the existence of a stable cluster size consisting of three interacting individuals.Comment: 8 pages, 5 figures, 2 table

A Process for ADM-300 Radiation Detector Modernization for Military Applications

An investigation to re-evaluate the current use in military applications of the ADM-300 Multi-Functional Survey Instrument and its requirements are provided. This paper outlines a method to upgrade the ADM-300 due to its eventual obsolescence using newly developed requirements that meet the original justification for use in the USAF in 1992. The capabilities and features of various detectors are analyzed and compared to the ADM-300. Response curves are generated using Monte Carlo simulations. The detectors are prioritized based on their performance to create metrics. A metanalysis of the metrics is conducted to limit bias within the process and justify their application in various military scenarios. The Colibri platform is the recommended replacement for the ADM-300 based on the method presented

Spectroscopy of 13B via the 13C(t,3He) reaction at 115 AMeV

Gamow-Teller and dipole transitions to final states in 13B were studied via the 13C(t,3He) reaction at Et = 115 AMeV. Besides the strong Gamow-Teller transition to the 13B ground state, a weaker Gamow-Teller transition to a state at 3.6 MeV was found. This state was assigned a spin-parity of 3/2- by comparison with shell-model calculations using the WBP and WBT interactions which were modified to allow for mixing between nhw and (n+2)hw configurations. This assignment agrees with a recent result from a lifetime measurement of excited states in 13B. The shell-model calculations also explained the relatively large spectroscopic strength measured for a low-lying 1/2+ state at 4.83 MeV in 13B. The cross sections for dipole transitions up to Ex(13B)= 20 MeV excited via the 13C(t,3He) reaction were also compared with the shell-model calculations. The theoretical cross sections exceeded the data by a factor of about 1.8, which might indicate that the dipole excitations are "quenched". Uncertainties in the reaction calculations complicate that interpretation.Comment: 11 pages, 6 figure

Different modes of variation for each BG lineage suggest different functions.

Mammalian butyrophilins have various important functions, one for lipid binding but others as ligands for co-inhibition of αβ T cells or for stimulation of γδ T cells in the immune system. The chicken BG homologues are dimers, with extracellular immunoglobulin variable (V) domains joined by cysteines in the loop equivalent to complementarity-determining region 1 (CDR1). BG genes are found in three genomic locations: BG0 on chromosome 2, BG1 in the classical MHC (the BF-BL region) and many BG genes in the BG region just outside the MHC. Here, we show that BG0 is virtually monomorphic, suggesting housekeeping function(s) consonant with the ubiquitous tissue distribution. BG1 has allelic polymorphism but minimal sequence diversity, with the few polymorphic residues at the interface of the two V domains, suggesting that BG1 is recognized by receptors in a conserved fashion. Any phenotypic variation should be due to the intracellular region, with differential exon usage between alleles. BG genes in the BG region can generate diversity by exchange of sequence cassettes located in loops equivalent to CDR1 and CDR2, consonant with recognition of many ligands or antigens for immune defence. Unlike the mammalian butyrophilins, there are at least three modes by which BG genes evolve.Wellcome Trust (Grant IDs: RG49834 (Studentship), 089305 and a Senior Investigator Award), Biotechnology and Biological Sciences Research Council (Studentship)This is the final version of the article.
