A NUMERICAL QUADRATURE APPROACH TO OPTION VALUATION IN WATER MARKETS AgEcon
Villinski, Michele T..
The standard Black-Scholes approach to option valuation becomes cumbersome and may fail to yield a solution when applied to non-standard options such as those emerging in water markets. An alternative tool, numerical quadrature, avoids some restrictive assumptions of the Black-Scholes framework and can more easily price options with complex structures.

A partial revision of the Hippomaneae (Euphorbiaceae) in Malesia Naturalis
Esser, Hans-Joachim.
The Hippomaneae (Euphorbiaceae) are revised for Malesia. Only Excoecaria and Homalanthus are excluded. A key to all Malesian genera is provided. The generic concepts applied differ markedly from previous treatments for the region with the following genera accepted: Balakata, Falconeria, Gymnanthes, Microstachys, Sapium, Shirakiopsis, Stillingia and Triadica. All of these genera show peculiarities in biogeography and ecology, which are discussed. Among these genera only Stillingia is kept as traditionally used. Balakata (based on Sapium sect. Pleurostachya) and Shirakiopsis (based on Sapium sect. Parasapium but excluding its type) are described as new genera; Falconeria, Microstachys and Triadica are re-established as distinct genera having been treated as...

A peculiar behaviour for cell death induced by weak carboxylic acids in the wine spoilage yeast Zygosaccharomyces bailii IPB - Escola Superior Agrária
Estevinho, Leticia M.; Côrte-Real, Manuela; Leão, Cecília.
In glucose-grown cells of Zygosaccharomyces bailii, ISA 1307 acetic acid and other carboxylic acids enhanced death. The effects were much lower than those described for Saccharomyces cerevisiae, being only detectable at higher acid concentrations. In Z. bailii, acetic acid and other weak acids also induced intracellular acidification, but this effect was less pronounced than that of death and no relationship was found with death enhancement. The results suggested that in Z. bailii, unlike S. cerevisiae, intracellular acidification induced by weak acids is less pronounced and appears not to have a significant role in death at the temperature range used.

A pesquisa em agricultura familiar no semi-arido: metodos alternativos de diagnostico e validacao de tecnologias. Repositório Alice
GUIMARAES FILHO, C.; SABOURIN, E.; SILVA, P. C. G. da; CORREIA, R. C..
Abrigando mais da metade dos estabelecimentos rurais de base familiar do pais, o Nordeste brasileiro esta ameacado de ver a maior parte desse imenso potencial de trabalho e producao desaparecer, em funcao de politicas publicas de desenvolvimento ineficazes, em termos de permitir uma efetiva insercao dessas unidades no mercado, de modo especial na regiao semi-arida. A pesquisa agricola compartilha responsabilidade nesse processo, uma vez que nao foi capaz de incorporar as suas acoes uma visao mais abrangente da problematica do agricultor familiar. Essa situacao comeca, contudo a se modificar na regiao. As experiencias de construcao de metodologias multidisciplinares e participativas adaptadas a realidades locais, comecam a se multiplicar, prenunciando a...

A Portfolio Approach to Cooperative Price Risk Management AgEcon
Gjolberg, Ole; Steen, Marie.
Agricultural producers face significant price risk. For some products, farmers may hedge this risk in well-functioning futures markets. For several products, however, no such risk management instrument is readily available. We suggest that farmers reduce price risk by organizing cooperatives where members diversify by creating "accounting" portfolios. The approach is illustrated with data from the Dutch flower market, and some practical problems connected to such cooperative risk pooling in agriculture are addressed.

A potencialidade da microscopia de varredura por sonda na pesquisa agropecuária. Infoteca-e
HERRMANN JUNIOR, P. S. de P.; COLNAGO, L. A.; MATTOSO, L. H. C.; VAZ, C. M. P..
O microscópios têm sido peça fundamental na abertura de novas fronteiras em ciência. O microscópio ótico revolucionou a biologia permitindo aos cientistas obter imagens de células vivas, e com o advento da microscopia eletrônica aprofundou-se o entendimento das estruturas da célula e de materiais orgânicos.

A preliminary assessment of coral bleaching in Mozambique OceanDocs
Schleyer, M.; Obura, D.; Motta, H.; Rodrigues, M.J..
The 1997-1998 El Niño southern oscillation caused elevated sea temperatures that resulted in global coral bleaching. Coral reefs constitute an important biological resource in terms of their complex biodiversity and are the basis for tropical fisheries and marine ecotourism. They represent one of Mozambique’s main coastal assets, and coastal communities and the growing tourism industry rely mainly on reef-based resources. Today, about 6.6 million people live within Mozambique’s 48 coastal administrative districts. This represents 42% of the current population (15.7 million), which is expected to grow at 3% p.a. (INE, 1998). In 1994, the population density in coastal districts was 28 persons/km2. In 1996, much higher densities were recorded in the coastal...

A Preliminary Assessment of Coral Bleaching in Mozambique OceanDocs
Schleyer, M.; Obura, D.; Rodrigues, M.J..
The 1997-1998 El Nino southern oscillation (ENSO) caused elevated sea temperatures that resulted in global coral bleaching. Coral reefs constitute an important biological resource in terms of their complex biodiversity and are the basis for tropical reef fisheries and marine ecotourism. They represent one of Mozambique's main coastal assets and its coastal communities and growing tourism industry rely mainly on reef-based resources. Mozambican artisanal fisheries are largely centred on reefs and are responsible for about 70% of the total catch, highlighting their importance. Most tourism similarly occurs along the coast where the best infrastructure is established, especially near the coral reefs of Pemba, Mozambique Island, the Bazaruto Archipelago,...

A PRELIMINARY FEASIBILITY FOR ESTABLISHING A MULTI-SPECIES MEAT PROCESSING PLANT IN SOUTHWESTERN NORTH DAKOTA AgEcon
Nudell, Daniel J.; Kraenzel, David G.; Petry, Timothy A.; Faller, Timothy; Hughes, Harlan G.; Brown, Erin.
The number of small commodity livestock slaughter plants in the Upper Northern Plains region continues to decline. Significant factors contributing to this decline include: 1) pressure to consolidate, thereby capturing economies of scale; 2) relatively stringent federal inspection specifications, along with; 3) HACCP (Hazardous Analysis Critical Control Points) requirements. At the same time, consumer demand (markets) for specialty, selected, and exotic meats appears to be growing. For example, the recent market successes in Europe evidenced by the North American Bison Cooperative based in New Rockford, North Dakota. Several alternative livestock producer groups have emerged which include lamb, ratite, elk, deer, goat, poultry, rabbit, specialty beef,...

A Principal-Agent Analysis of the Family: Implications for the Welfare State AgEcon
Munro, Lauchlan.
The principal-agent literature has focussed on situations where both principal and agent are assumed to be capable of defining and defending their own interests. The principal-agent literature has thus ignored an important set of cases where the principal is incapable of acting on her own behalf, and so is assigned an agent by law or custom. Such cases account for around 40% of humanity and for a similarly substantial proportion of all principal-agent interactions. This paper applies principal-agent analysis to one such case, the family, where the child is taken as the principal and the parent is her agent. The principal-agent problem within families creates a prima facie case for state interventions to protect child-principals, since some parents will...
