the study on gender and net farm income of cassava-based farmers under individual land tenure system was done in abia state of nigeria. the main objective was to determine the net farm income (nfi) and the benefit cost ratio (bcr) of the cassava farmers by gender vis-aviz their income levels as well as food security in the state. a multi-stage random sampling technique was adopted while data we...

Weitzman (1998) showed that when future interest rates are uncertain, using the expected net present value implies a term structure of discount rates that is decreasing to the smallest possible interest rate. On the contrary, using the expected net future value criteria implies an increasing term structure of discount rates up to the largest possible interest rate. We reconcile the two approach...

We aimed to develop alternative fishing gear for catching the common octopus, to decrease the use of bait and operating costs in comparison to commercial net pots. A tubular-type pot was designed, and behavioral responses of the common octopus were experimentally monitored in tank and replicated 10 times to compare fishing performances between 300 experimental and 300 commercial net pots in the...

The aim of a multi-mode resource-constrained project scheduling problem (MRCPSP) is to assign resource(s) with the restricted capacity to an execution mode of activities by considering relationship constraints, to achieve pre-determined objective(s). These goals vary with managers or decision makers of any organization who should determine suitable objective(s) considering organization strategi...

Previously, comparisons of multiple strategies in health technology assessment have been undertaken on the incremental cost-effectiveness plane using efficiency frontiers and cost-effectiveness acceptability curves. This article proposes shifting the comparison of multiple strategies to the cost-disutility plane. Evidence-based decision making requires comparison of all strategies against each ...

This study aimed to economic evaluation of ostrich production in Sistan region by the use fuzzy conception in five platforms including (1 bird, 30 birds, 50 birds, 100 birds and 200 birds). The result showed that amount of benefit cost for 30, 50, 100 and 200 was 0.20, 0.26, 0.30, 0.31 and present value was 105, 549, 1460, 2927 million rials. According to the results obtained from present value...

The Resource-constrained Project Scheduling Problem (Rcpsp), in which a schedule must obey resource constraints and precedence constraints between pairs of activities, is one of the most studied scheduling problems. An important variation of this problem (RcpspDc) is to find a schedule which maximises the net present value (discounted cash flow). Large industrial applications can require thousa...

Improvement and expansion of the transmission grid is still an unresolved issue in the new competitive environment. In current electricity markets, transmission lines have become assets that need financial instruments for investors who wish to ensure steady long-term returns and to withstand short-term market volatility. The timing and the combination of new transmission investments is key to a...
