PREMIUMS/DISCOUNTS AND PREDICTIVE ABILITY OF THE SHRIMP FUTURES MARKET

Seafood futures contracts are a novelty in the derivative markets, having shrimp as their only exponent. Unfortunately, shrimp futures contracts have suffered a disappointing start. The analyses focus on testing whether premiums/discounts for non-par deliverable shrimp size categories can eliminate cash price differentials, and whether the shrimp futures market can predict cash prices without bias. Results indicate ineffective premiums/discounts and predictive bias. These results and the momentous changes taking place in the seafood industry are contrasted to discuss the viability of seafood futures contracts.Agribusiness,

Innovations and Progress in Seafood Demand and Market Analysis

The purpose of this paper is to review several economic studies which present a spectrum of interesting and creative approaches to analyzing the market for fish and seafood. These studies form a basis from which to offer recommendations for further improving analysis of fish demand and markets. We do so in an effort to advocate the potential of this area of research in the decisions which promote efficient use of the world's fisheries resources. Each of the reviewed approaches has its merits and limitations, depending on the issue at hand, quality of the data and skills of the researcher. The approaches are categorized as either demand studies following more traditional commodity market analysis methods or as market research studies.seafood, demand, marketing, international trade, Demand and Price Analysis, Environmental Economics and Policy, International Relations/Trade, Resource /Energy Economics and Policy,

Effects of hydrolysis ageing on the performance and dimensional stability of glass-fiber reinforced polyamide 66

Results of an in-depth study of hydrolysis testing on the mechanical performance, weight change, and dimensional stability of injection moulded glass-fiber reinforced polyamide 66 automotive composites are presented. Composite and resin samples have been characterised after conditioning in water-glycol mixtures at 70°C, 120°C and 150°C for a range of times up to 1000 hours. The results reveal that hydrothermal ageing results in significant changes in the mechanical performance, weight, and dimensions of these materials. Mechanical performance after conditioning at different temperatures could be superimposed when considered as a function of the level of fluid absorbed by the composite matrix

Three-dimensional multigrid algorithms for the flux-split Euler equations

The Full Approximation Scheme (FAS) multigrid method is applied to several implicit flux-split algorithms for solving the three-dimensional Euler equations in a body fitted coordinate system. Each of the splitting algorithms uses a variation of approximate factorization and is implemented in a finite volume formulation. The algorithms are all vectorizable with little or no scalar computation required. The flux vectors are split into upwind components using both the splittings of Steger-Warming and Van Leer. The stability and smoothing rate of each of the schemes are examined using a Fourier analysis of the complete system of equations. Results are presented for three-dimensional subsonic, transonic, and supersonic flows which demonstrate substantially improved convergence rates with the multigrid algorithm. The influence of using both a V-cycle and a W-cycle on the convergence is examined

Solid-state conformation of copolymers of ß-benzyl-L-aspartate with L-alanine, L-leucine, L-valine, γ-benzyl-L-glutamate, or ε-carbobenzoxy-L-lysine

The solid-state conformation of copolymers of ß-benzyl-L-aspartate [L-Asp(OBzl)] with L-leucine (L-Leu), L-alanine (L-Ala), L-valine (L-Val), γ-benzyl-L-glutamate [L-Glu(OBzl)], or ε-carbobenzoxy-L-lysine (Cbz-L-Lys) has been studied by ir spectroscopy and circular dichroism (CD). The ir spectra in the region of the amide I and II bands and in the region of 700-250 cm-1 have been determined. The results from the ir studies are in good agreement with data obtained by CD experiments. Incorporation of the amino acid residues mentioned above into poly[L-Asp(OBzl)] induces a change from the left-handed into the right-handed α-helix. This conformational change for the poly[L-Asp(OBzl)] copolymers was observed in the following composition ranges: L-Leu, 0-15 mol %; L-Ala, 0-32 mol %; L-Val, 0-8 mol %; L-Glu(OBzl), 3-10 mol %; and Cbz-L-Lys, 0-9 mol %

A Spatial Economic Model of Maine\u27s Forest Product Industry: Interactions Between Markets, Policy, and Space

Recognizing the extensive historical and modern role of forests in Maine, this dissertation proposes a new dynamic-recursive, spatial allocation (DR.SAGE) model for examining Maine’s forest economy to understand its continuing importance to the state. This model attempts to incorporate spatial elements into a general equilibrium framework to evaluate how shocks to the forest products markets, such as a large increase in exports each year, would ripple through Maine, where forest related goods are the primary export. By adjusting previous estimates, contribution analyses for 2016 estimate that the forest products industry supports a $8.5B contribution to Maine. From here, it is projected that Maine’s economy will grow just under 5% by 2025 with business as usual: a 5.3% increase in GDP and a 4.7% increase in annual harvests. Driven by inflation, prices will increase an average of 22.1% by 2025. During this time, some production moves into the central counties of York, Cumberland, Androscoggin, Kennebec, and Penobscot from the others. Using the DR.SAGE model to analyze a spruce budworm infestation, I estimate that medium- and high intensity outbreaks will have long term consequences on the stock of softwood saw logs. I also estimate that an external increase in the demands for forest products of 15.6% over nine years would increase most forest product sectors’ outputs and prices by an additional 4%-10%; forest product sectors with proportionally large wood requirements and large export shares expanded the most. Despite this, Maine’s GDP is estimated to grow only by an additional 0.1%-0.2%. Sectors which are not related to Maine’s forest economy saw minimal decreases in price and output, while sectors competitive with forest sectors saw declines of 0.3%-0.6%. Overall, the DR.SAGE model framework meets the project objectives: it provides details about harvest levels and locations for a variety of wood types; the stock of each wood types is grown endogenously in the model; it provides information about each broad sector’s production in each county; and, it provides aggregate information about prices and county-level output for the forest product sectors
