Selected facets of the fishing industry (early 1963)

<p>Consumer demand, retail distribution and the export trade are important aspects of the New Zealand Commercial Fishery which are outside the specific boundaries of this enquiry. It is a study in government intervention, price negotiation and supply. In analysing these three facets of the industry it was impossible to ignore the other three so they have been treated incidentally where a discussion of them was necessary to understand the central theme. There is scope for additional research into each of the above topics, perhaps more especially into administrative decision making when non economic objectives are involved and also into the optimum scale of plant given the cost conditions that apply to the industry. However, it is hoped that this essay goes part of the way towards meeting the need for fundamental economic research into an industry which periodically attracts the attention of the public, policy makers and Government. Parliament has set up three committees in the past twenty-six years to examine the industry.</p>

Performance Analysis of Optimal Sized Hybrid Renewable Energy Grid-Connected Systems.

Hybrid solar energy-based power generation systems (PGS) are one of the exciting options for potential distributed networks. PV and wind grid linked PGSs are the most appropriate for its good output across various configurations. However, due to the system's complexity, special attention is required to achieve a successful engineering solution in the optimal balance between these two energy sources. This paper discusses optimum scale of PV and wind by following multiple optimization methods to various condition decision analysis (VCDA). The versatility of the VCDA algorithm was tested by taking into account several weighting parameter techniques for differing wind speeds and fluctuations in radiation levels, thus illustrating the advantages and limitations of the suggested optimum size approaches. The subsequent study may be called as a significant reference for decision makers, analysts and policymakers.

Efficient Utilisation of Credit by The Farmer-Borrowers in Chittoor District of Andhra Pradesh, India

The present study has aimed at analyzing the technical and scale efficiencies of credit utilization by the farmer-borrowers in Chittoor district of Andhra Pradesh, India. DEA approach was followed to analyze the credit utilization efficiency and to analyze the factors influencing the credit utilization efficiency, log-linear regression analysis was attempted. DEA analysis revealed that, the number of farmers operating at CRS are more in number in marginal farms (40%) followed by other (35%) and small (17.5%) farms. Regarding the number of farmers operating at VRS, small farmers dominate the scenario with 72.5 per cent followed by other (67.5%) and marginal (42.5%) farmers. With reference to scale efficiency, marginal farmers are in majority (52.5%) followed by other (47.5%) and small (25%) farmers. At the pooled level, 26.7 per cent of the farmers are being operated at CRS, 63 per cent at VRS and 32.5 per cent of the farmers are either performed at the optimum scale or were close to the optimum scale (farms having scale efficiency values equal to or more than 0.90). Nearly 58, 15 and 28 percents of the farmers in the marginal farms category were found operating in the region of increasing, decreasing and constant returns respectively. Compared to marginal farmers category, there are less number of farmers operating at CRS both in small farmers category (15%) and other farmers category (22.5%). At the pooled level, only 5 per cent of the farmers are operating at DRS, majority of the farmers (73%) are operating at IRS and only 22 per cent of the farmers are operating at CRS indicating efficient utilization of credit. The log-linear regression model fitted to analyze the major determinants of credit utilization (technical) efficiency of farmer-borrowers revealed that, the three variables viz., cost of cultivation and family expenditure (both negatively influencing at 1% significant level) and family income (positively influencing at 1% significant level) are the major determinants of credit utilization efficiency across all the selected farmers categories and at pooled level. The analysis further indicate that, escalation in the cost of cultivation of crop enterprises in the region, rise in family expenditure and prior indebtedness of the farmers are showing adverse influence on the credit utilization efficiency of the farmer-borrowers.

How Long is Indian Coastline?

Coastline measurements have no explicit length if they are geometrically self-similar. It is well known that length of self-similar geometrical objects is scale dependent, and hence it is not a fixed number, rather depends on the scale used to measure it. We present a definitive approach based on a fractal method to measure the coastline of India. We propose a method to define optimum scale length, that could be used to measure the coastline. Using our method, the mainland coast measures 7567 km. There are four big inhabited islands in Andaman (North, Middle, South and Little Andaman) which accounts for 687 km of island coast, and Great Nicobar Island has 195 km of coast around it, thus coastal length of inhabited islands is 882 km. Thus the total coast length of India including major 5 inhabited islands from Andaman-Nicobar group of islands is 8391 km. There are several other small islands in Andaman-Nicobar group of islands, we observed 26 of them significant in terms of their size. Indian coast length becomes 9060 km if we account for above mentioned 26 Andaman and Nicobar Islands. According to one of the Wiki articles, there are 572 islands in Andaman-Nicobar group of islands, but many of them are very small and insignificant. This is first ever scientific study about the Indian coast length, which has global significance due to strategic and climate related coastline alterations such as sea level rise due to global warming.

μSR Spectrum Reconstruction Using Monte Carlo Approach: A Preliminary Study

A possible method to reconstruct μSR spectra using Monte Carlo approach presented. Three issues carefully addressed for the simulations, that is automatic muon sites estimations, movement of muon due to gradient electrostatic potential and thermal fluctuation. All minima within the unit cell need to be included for more realistic theoretical μSR spectra. The optimum scale of gradient potential and thermal fluctuation needed to achieve a realistic result. Additional μSR spectra can be revealed in comparison with the simulation at lower thermal fluctuation.

Productivity, Technology and Efficiency Change of Islamic and Conventional Reits in Malaysia

Problem/Purpose – The paper examined total factor productivity changes namely Malmquist Productivity Index (MPI) for the Malaysian Real Estate Investment Trust (M-REITs) by drawing attention to the Islamic and conventional REITs Design/methodology/approach – Data was attained from annual reports for the period of 2007 to 2015. The non-parametric approach of MPI-DEA examined the productivity, technological and efficiency change indices. Findings – The result suggested both Islamic and conventional REITs have exhibited productivity regress of 18.09% and 11.51% respectively during the period of study. These productivity regress could mainly due to the regress in technological rather than efficiency change. One possible reason for this technological regress is likely due to REIT requirement in which the REIT managers could not retain their earning and reinvest their income for the following year. The REIT managers need to have access to external capital for purchasing new asset, which could lead to a higher cost of capital than the retained earnings. On the other hand, both conventional and Islamic REITs exhibited an increase of 28.33% and 61.54% respectively for efficiency change, mainly due to an increase in managerial rather than scale, implying that both REITs have been managerially efficient in managing the operating costs but operating at the non-optimum scale of operations. Research limitations/implications –This study provide empirical evidence on the source of productivity regress for M-REITs and insights on the comparative analysis of Islamic and conventional REITs. Future research suggested to be undertaken include the identification of key determinants for the productivity changes of M-REITs using the parametric approach. Originality/value – This paper is the first analysis on the productivity changes of Islamic REITs vis-à-vis conventional REITs. By examining these values, the identification of main sources of Malaysian Islamic REITs productivity regress assist M-REIT managers to develop strategies in improving their REIT productivity and provide competitive edge in the market.
