A marketing-finance approach linking contracts in agricultural channels to shareholder value AgEcon
Pennings, Joost M.E.; Wansink, Brian; Hoffmann, Arvid O.I..
A conceptual marketing-finance framework is proposed which links channel contracting in agriculture and the use of financial facilitating services (e.g., financial derivatives) to (shareholder) value creation. The framework complements existing literature by explicitly including channel contract relationships as market-based assets that can be managed to reduce cash flow volatility and hence increase shareholder value. We show how financial facilitating services (e.g., derivatives) can be used to complement the cash flows components of channel contract relationships thereby further reducing the risk adjusted cost of capital and improving shareholder value. In a field study of producers, wholesalers, and processors, in the potato and meat industry the...

Análisis de la información de infraestructura hidroagrícola en distritos de riego. Colegio de Postgraduados
Tovar Tapia, Víctor Gregorio.
México ocupa el sexto lugar mundial en términos de superficie con infraestructura de riego con 6.46 millones de hectáreas, de las cuales el 54% corresponde a 85 Distritos de Riego (DR), y el restante a más de 39 mil Unidades de Riego (UR).Por lo anterior surge la inquietud de cuantificar con exactitud la infraestructura para su control, mantenimiento y actualización, ya que en la actualidad en algunos casos la información con la que cuenta la Comisión Nacional del Agua (CONAGUA)posiblemente no ha sido actualizada oportunamente. El objetivo del presente análisis es comparar la información sobre infraestructura agrícola que existe en forma oficial y la obtenida a través de sistemas de información geográfica (SIG) con que cuenta la misma CONAGUA y evaluar la...

Analyse des effets de l'ouverture du chenal de Grand Bassam (estuaire du fleuve Comoé, lagune Ebrié) sur la macrofaune benthique lagunaire. OceanDocs
Sankaré, Y.; Etien, N..
Cet article présente les résultats d'une étude comparative de trois séries de prélèvements dans la zone proche du canal de Bassam avant, 6 mois et 20 mois après son ouverture en septembre 1987. Les effets constatés sont la diminution de l'abondance et la modification de la composition de la macrofaune benthique. Ces effets semblent de longue durée, sans reprise en ce qui concerne l'espèce la plus abondante, Corbula trigona. Les changements observés dans la structure des peuplements sont dus essentiellement à l'augmentation de la salinité, et à un degré moindre, aux modifications de la nature du sédiment.

Caracterización del régimen de mareas y corrientes a lo largo del canal Moraleda (43° 54' S - 45° 17' S) OceanDocs
Fierro, J.; Bravo, M.; Castillo, M..
Sea level and currents in “Boca del Guafo” and Moraleda channel are studied using statististical and Fourier (harmonic) analyses. The data were collected using oceanographic instruments that covered a wide geographical area, from the northern most point of Moraleda channel to Darwin channel. The results of the harmonic analysis indicated that the area has a semidiurnal tide with a 12-minute phase shift between the ports of Melinka and Lagunas. This result shows that the tidal wave does not only propagate along the Moraleda channel, but at the same time enters the region through several transversal channels that connect the Pacific Ocean with the Moraleda channel. Along the main channel (Moraleda) no reverse current was recorded, which is an unusual...

Distribución espacial del amonio en fiordos y canales comprendidos entre Puerto Montt y Laguna San Rafael en período de primavera OceanDocs
Prado-Fiedler, R..
An oceanographic expedition was carried out between October 18th and November 15th 1995 in the inlets region and fjords located between Puerto Montt (41° 20’S and San Rafael Lagoon (46° 40’ S) in Southern Chile. The main purpose of the present work is to characterise the spatial distribution of ammonium and its concentration range in the studied region during spring onset. Water samples were collected from a total of 101 oceanographic stations of the expedition Cimar-Fiordo 1. The main part of the water body showed concentrations lower than 1 µmol/L. The higher ammonium concentrations were found in the continental fjords, specially in the area situated south of the narrows of Meninea island, where subsurface maximums greater than 2 µmol/L were found. The...

Divalent cations as modulators of neuronal excitability: Emphasis on copper and zinc Biol. Res.
DELGADO,RICARDO; VERGARA,CECILIA; WOLFF,DANIEL.
Based on indirect evidence, a role for synaptically released copper and zinc as modulators of neuronal activity has been proposed. To test this proposal directly, we studied the effect of copper, zinc, and other divalent cations on voltage-dependent currents in dissociated toad olfactory neurons and on their firing rate induced by small depolarizing currents. Divalent cations in the nanomolar range sped up the activation kinetics and increased the amplitude of the inward sodium current. In the micromolar range, they caused a dose dependent inhibition of the inward Na+ and Ca2+ currents (I Na and I Ca) and reduced de amplitude of the Ca2+-dependent K+ outward current (I Ca-K). On the other hand, the firing rate of olfactory neurons increased when exposed to...

Impact of improvement of the entrance channel on the rate of sediment deposition into the Dar es Salaam Harbour OceanDocs
Dubi, A.M.; Sanga, I.P.L..
The study reported here sought to investigate the effect that the dredging of the harbour basins and the entrance channel has had on sediment deposition rate into the Dar es Salaam harbour. Echo-sounding was carried out along berths No 2, 3, 4, 6, 7 and 8 as a means of detecting changes to their bathymetry in the four years since 1998, when the dredging commenced. Concentrations of transported sediments into and out of the harbour were determined using sediment traps. Short-term measurement of waves and currents were also carried out. Sediment traps, a wave-gauge and a current-meter were deployed in the entrance channel during the South East and North East monsoon seasons respectively. Our results reveal that the sedimentation rates after improvement of...

PRIMER REGISTRO EN COLOMBIA DE CORBICULA FLUMINEA (MOLLUSCA: BIVALVIA: CORBICULIDAE), UNA ESPECIE INVASOR Boletín de Investigaciones
De La Hoz Aristizábal,Maria V..
The bivalve Corbicula fluminea Müller is recorded for the first time in Colombia, in the National Park Isla de Salamanca. This protected area includes freshwater channels and mixohaline lagoons influenced by waters of both the Magdalena River and the Caribbean Sea. This exotic bivalve occurs locally in freshwater channels close to the Magdalena River as well as in the latter, whereas another corbiculid native species, Polymesoda solida, is commonly found in the mixohaline lagoons. Densities of C. fluminea ranged from 10 to 100 ind/m2 along with low numbers of P. solida. Lengths ranged form 10 to 43 mm in a predominant muddy substrate. Local fishermen have stated that C. fluminea was established approximately in 1992; this clam is being artisanally...

Testing the Theory: Vertical Strategic Interaction and Demand Functional Form AgEcon
Cotterill, Ronald W.; Putsis, William P., Jr..
Formulating theoretical models inevitably requires various simplifications that assist in making analysis tractable and that facilitate deriving closed form solutions. While the strategic insights gained from theoretical models of market phenomena are often quite valuable, testing the theoretical assumptions made in these models can aid in assessing the broader applicability of the conclusions drawn. This is particularly true in the channels area, where the focus of research to date has largely been theoretical in nature. In an initial attempt to examine some of the assumptions made in previous theoretical research (e.g., Jeuland and Shugan 1983, McGuire and Staelin 1983, Choi 1991, Raju, Sethuraman and Dhar 1995), we focus on a limited set of issues....

The Celtic Sea banks: an example of sand body analysis from very high-resolution seismic data ArchiMer
Marsset, Tania; Tessier, Bernadette; Reynaud, Jean-yves; De Batist, M; Plagnol, Clara.
Very high-resolution seismic data from the Kaiser-I-Hind sand bank (southern Celtic Sea) recently highlighted the internal structure of the enigmatic Celtic Banks, which are among the deepest and largest shelf sand ridges. The main body of the bank is made up of 4 seismic/depositional units which reflect a transgressive evolution. New data on the detailed architecture of two of these units allow discussion of bank growth in terms of either (1) a channel–levee system preserved both by lateral migration and aggradation of the channels, or (2) a package of large offshore tidal sediment bodies (bar chains and/or giant dunes). Careful geometrical observations of seismic discontinuities make the second hypothesis more likely. The unit architecture is analysed in...

To be or not to be… Nicotinic acid adenine dinucleotide phosphate (NAADP): A new intracellular second messenger? Biol. Res.
NUNES CHINI,EDUARDO.
Nicotinic acid adenine dinucleotide phosphate (NAADP) is a potent activator of intracellular Ca2+ release in several vertebrate and invertebrate systems. The role of the NAADP system in physiologicalprocesses is being extensively investigated at the present time. The NAADP receptor and its associated Ca2+ pool have been hypothesized to be important in several physiologicalprocesses including fertilization, T cell activation, and pancreaticsecretion. However, whether NAADP is a new second messenger ora tool for the discovery of a new Ca2+ channel is still an unansweredquestion. Research developed over the last two years has provided some important clues to whether NAADP is or not a physiological cellular messenger. In this short review, I will discuss some...
