Capacity and scale inefficiency: Application of data envelopment analysis in the case of the french seaweed fleet ArchiMer
Guyader, Olivier; Daures, Fabienne.
Data Envelopment Analysis (DEA) models are applied to the main French seaweed fleet to examine capacity output, capacity utilization, and scale inefficiency. Coastal seaweed vessels target only one output - kelp - with the same gear but with different input level combinations. The fishery is seasonal and subject mainly to input regulations, especially a one trip per day regulation implemented in 1987. The consequence was a decline in total observed output and a fall in capacity output and efficient output. Only the largest vessels and a few small vessels harvesting without this regulatory constraint operate at the optimal scale. The question of a change in regulation, especially a shift to an individual quota system, is raised.

Decommissioning schemes and capacity adjustment: A preliminary analysis of the French experience ArchiMer
Guyader, Olivier; Berthou, Patrick; Daures, Fabienne.
The French decommissioning aims at permanently removing vessels from the fishing fleet according to European Union rules laid down within the Common Fisheries Policy. A system of premiums established by the French government is supposed to give the vessel-owners, the incentives to get rid of their fishing unit. This paper details the rules for the applicants and their evolution and it provides a preliminary analysis of the impact of these schemes over the 1991-2001 period. Special attention is paid to the characteristics of decommissioned vessels and of their owners. The problem of windfall gains of these policies is approached, and a first assessment is given. The consequences in terms of capacity adjustment are discussed according to the Multi Annual...

DESIGN AND FABRICATION OF A SCREW CONVEYOR CIGR Journal
Olanrewaju, Taofiq Olayinka.
Grain must be transported from one location to another. Several disadvantages are associated with grain transportation, especially manual loading into trailers and silos. The need for a grain handling equipment became pertinent; hence, this study designed and fabricated a simple and medium size auger aimed at conveying grains upward into a silo. The conveyor was fabricated from pure local materials considering the techno – economic properties. Tests were run on the conveyor using granular materials like maize, sorghum and gari at 13% moisture content. The angles of test were 00, 150, 300, 450, and 600 for each grain. It was found capable of loading an average size silo of 2.68 m3 in 15 minutes. The conveyor has an efficiency of 99.95%, and average output...

Design, fabrication and performance evaluation of a small drum type potato grader CIGR Journal
HUDA, MD. NAZMUL.
AbstractGrading potatoes by size is an important operation for preparing tubers for seed and for commercial purposes. If potatoes were sold after grading, this would be beneficial to both producers and consumers. Since mechanical graders are not locally available, potatoes are graded, when necessary, by hand. This is a time consuming, costly, and inefficient method. This work concerns the development of a potato-grading machine for small-scale farmers. The grader consisted of a hopper, grading unit, prime mover and catchment tray fitted on a frame. The grader was made of locally available materials to keep the cost low. The grading unit was made up of plastic oil container, hopper and catchment tray made up of mild steel sheet and the frame was made up of...

Gohiya,Vineet Kumar; Shrivatava,Sudha; Gohiya,Sarita.
It is known that there exists close relationship between cranial capacity and size of the brain. Several studies have estimated the cranial capacity, which indirectly reflects the brain volume in different populations. The aim of this study was to estimate cranial capacity of a particular age group of population of Madhya Pradesh. This study was carried out on 400 healthy 20-25 year old (200 male and 200 female) individuals of Madhya Pradesh state of India, by using linear dimensions of head (Lee Pearson's formula). The mean cranial capacity and SD in males &amp; females were 1380.52±94.63 cc and 1188.75±91.16 cc respectively. This study has shown a significant (p<0.05) difference between male and female population, being higher in males than in...

Formation en Développement durable des villages de pêche des pays de l’Afrique de l’Ouest et du Centre OceanDocs
Thiam, Mamadou.
Le secteur de la pêche traverse des difficultés énormes au Sénégal. Les revenus tirés de l’exercice de cette activité n’arrivent plus à satisfaire les besoins des populations. Conscientes de ce fait, les autorités du Ministère ont pris des initiatives importantes, dans le cadre de la politique sectorielle, parmi lesquelles, l’amélioration des conditions de vie et d’existence des populations pêcheurs. C’est pourquoi, ces dernières sont de plus en plus responsabilisées dans une approche « bottom up » qui voudrait que les décisions puissent être prises par les communautés à la base. Pour cela, il faudrait que les acteurs soient bien organisés et capables de prendre en charge les nouvelles responsabilités qui leur sont transférées. C’est pourquoi, le Ministère...

Letting the managers manage: analyzing capacity to conserve biodiversity in a cross-border protected area network Ecology and Society
Clement, Sarah; Department of Geography and Planning, School of Environmental Sciences, University of Liverpool ; Sarah.Clement@liverpool.ac.uk; Moore, Susan A; Environment and Conservation Sciences, School of Veterinary and Life Sciences, Murdoch University; S.Moore@murdoch.edu.au; Lockwood, Michael; Geography and Spatial Sciences, School of Land and Food, University of Tasmania; Michael.Lockwood@utas.edu.au.
Biodiversity loss is one of the most significant drivers of ecosystem change and is projected to continue at a rapid rate. While protected areas, such as national parks, are seen as important refuges for biodiversity, their effectiveness in stemming biodiversity decline has been questioned. Public agencies have a critical role in the governance of many such areas, but there are tensions between the need for these agencies to be more &#8220;adaptive&#8221; and their current operating environment. Our aim is to analyze how institutions enable or constrain capacity to conserve biodiversity in a globally significant cross-border network of protected areas, the Australian Alps. Using a novel conceptual framework for diagnosing biodiversity institutions,...

MARKET POWER AND EFFICIENCY IN A COMPUTATIONAL ELECTRICITY MARKET WITH DISCRIMINATORY DOUBLE-AUCTION PRICING AgEcon
Tesfatsion, Leigh; Petrov, Valentin; Nicolaisen, James.
This study reports experimental market power and efficiency outcomes for a computational wholesale electricity market operating in the short run under systematically varied concentration and capacity conditions. The pricing of electricity is determined by means of a clearinghouse double auction with discriminatory midpoint pricing. Buyers and sellers use a modified Roth Erev individual reinforcement learning algorithm to determine their price and quantity offers in each auction round. It is shown that high market efficiency is generally attained, and that market microstructure is strongly predictive for the relative market power of buyers and sellers independently of the values set for the reinforcement learning parameters. Results are briefly compared...
