PRODUCTIVITY GROWTH IN THE CARIBBEAN: A MEASURE OF KEY COMPONENTS

Productivity growth is decomposed into two components: technical change and efficiency change. This assesses their relative importance to the international competitiveness of the agricultural sectors of selected Caribbean countries. A nonparametric programming method is employed to compute Malmquist multifactor productivity indexes, which contrasts the innovation of races of these countries.

AGRICULTURAL INDUSTRIALIZATION AND SUSTAINABLE DEVELOPMENT: A GLOBAL PERSPECTIVE

Agricultural industrialization and sustainable development issues are important contemporary areas of debate. This paper argues that the two processes are a consequence of a set of forces operating in our global system. It outlines a number of conceptual interactions between the two phenomena and examines economic development and sustainable development policy implications that appear to be logical extensions of the arguments presented.Agricultural industrialization, Sustainable agricultural development, Development assistance, Human capital, Market and policy failures, Public policy, Environmental Economics and Policy, Research and Development/Tech Change/Emerging Technologies,

Sesame ( Sesamum indicum

Studies were conducted during the 2007 and 2008 growing seasons under weed-free conditions in South Texas and the High Plains region of Texas to evaluate preemergence herbicides for sesame tolerance. No reduction in sesame stand was noted with any herbicide at south Texas location; however, at the High Plains location, linuron at the 2X rate reduced stand counts 28 days after treatment (DAT) in 2007 and diuron reduced sesame stand 147 DAT in 2008 when compared with the untreated check. At the 1/2X rate all herbicides exhibited minimal stunting while at the 1X rate stunting was variable and varied between locations. At the 2X rate, all herbicides caused sesame stunting compared to the untreated check. No herbicide, with the exception of linuron at the 2X rate in 2008 at the High Plains location, reduced sesame yield when compared with the untreated check. Although some herbicide treatments resulted in sesame stunting, this did not result in any yield reductions and this can be attributed to the ability of the sesame plant to compensate for injury and/or reduced stands

Proposal for the determination of nuclear masses by high-precision spectroscopy of Rydberg states

The theoretical treatment of Rydberg states in one-electron ions is facilitated by the virtual absence of the nuclear-size correction, and fundamental constants like the Rydberg constant may be in the reach of planned high-precision spectroscopic experiments. The dominant nuclear effect that shifts transition energies among Rydberg states therefore is due to the nuclear mass. As a consequence, spectroscopic measurements of Rydberg transitions can be used in order to precisely deduce nuclear masses. A possible application of this approach to the hydrogen and deuterium, and hydrogen-like lithium and carbon is explored in detail. In order to complete the analysis, numerical and analytic calculations of the quantum electrodynamic (QED) self-energy remainder function for states with principal quantum number n=5,...,8 and with angular momentum L=n-1 and L=n-2 are described (j = L +/- 1/2).Comment: 21 pages; LaTe
