An Application of Differential Subordination

We apply the general theory of differential subordination to obtain certian interesting criteria for -valent starlikeness and strong starlikeness. Some applications of these results are also discussed

Economic viability of mechanized fishing units and socio-economics of fishing ban in Kerala

In open access unregulated marine fisheries, the viability of a fishing unit greatly influences the entry or exit of vessels in the fishing industry. The economic performance of fishing operations is affected by various factors including fluctuations in revenue, diminishing catch per unit of effort, unforeseen increases in the cost of key inputs and catch and effort restrictions. Capital and labour will continue to enter the fishery until the economic rents are totally dissipated and profits to individual units are reduced to the level of their opportunity costs. In the long run, the reduction in catch rates lead to reduction in fishing effort levels. The economic performance also plays a crucial role in the investment decisions at micro level. The paper analyses the viability of various mechanized fishing units in the Kerala state using different economic and financial indicators. Socioeconomic impact of fishing ban on fishing labour was also worked out and suggestions were given for improving the livelihood security of fish workers

Sustainability of marine fish production in Kerala-A Bioeconomic analysis

The study has been undertaken in Kerala State in lndia with an - overall objective of analyzing the bioeconomic conditions of commercially exploited marine fishes for assessing their sustainability in the context of existing management practices. Maximum Sustainable Yield, Maximum Economic Yield and open access levels of yield and effort were analyzed using Gompertz-Fox growth model. The study concluded that the fishing effort exceeded the ecanomically optimal levels and there is unnecessary wastage of money, manpow and fuel in the fishing industry. The study stressed the urgent need for cap&lr@ fisheries management in the State which at present follows an open access fishery where regulations exist only in the form of seasonal -. closure in the monwan seaso

Supply - Demand Analysis of fish in India

The economic growth, population pressure and changes in the dietary pattern have contributed to the increase in demand for animal origin foods in lndia. The fish prices had increased many times than all other food items over the years. An analysis of fish demand and supply situation in lndia is done and projections were made for the year 2020. Price and income elasticities of fish demand were estimated using exponential function. Export demand and tastes and preferences of consumers were not included in the demand analysis. The fish supply was projected using trend extrapolation method. Estimates of demand model showed that the household expenditure on fish in general as elastic. The study revealed that with the projected population and percapita income growth rates, fish demand in year 2020 will exceed the total fish supply from marine, inland and aquaculture sectors with the current production trend

Feasibility of utilising address card system for obtaining accurate address of patients under programme conditions

An addresscard, one on which patient's home address is asked to be recorded by a person knowing for sure the patient's address, was investigated for acceptability and efficiency, in two Government hospitals located in semiurban areas and six Primary Health Centres located in rural areas in North Arcot district. In all 394 address-cards were given to the patients from the eight centres, of which 374 were returned with the address filled in, showing an acceptability rate of 95%. In all, 373 Type A letters were then posted to these addresscard addresses in respect of which acknowledgment cards were received back from 306 (82%) patients. For 140 patients, the recorded addresses were found to be the same as on the addresscard and the treatment card: In the remaining 233, there was some difference between the two addresses. Type B letters were then posted to the 233 patients at their treatment card address. No definite information was available regarding the receipt of one or both types of letters in respect of 80 patients; so, an attempt was made to visit these patients in their homes to find out the fate of these letters. Of these, no information could be collected in 9 patients. Out of 224 patients for whom information regarding the receipt of letter was available, 143 (64%) patients received both letters and 16 (7%) received neither Type A nor Type B letter. Twenty one (9%) had probably or definitely not received the Type A letter, but had received the Type B letter. Forty four (20%) had definitely or probably not received the Type B letter, but had received the Type A letter

CERTAIN SUBCLASSES OF ANALYTIC FUNCTIONS INVOLVING COMPLEX ORDER

Abstract In the present investigation, we consider an unified class of functions of complex order. Necessary and sufficient condition for functions to be in this class is obtained. The results obtained in this paper generalizes the results obtained by Srivastava and Lashin [10], and Ravichandran et al

Bioeconomic analysis of sustainability of marine fish production in Kerala

The study has been undertaken in Kerala State in India with an overall objective of analyzing the bioeconomic conditions of commercially exploited marine fishes for assessing their sustainability in the context of existing management practices. Maximum Sustainable Yield, Maximum Economic Yield and Open Access levels of yield and effort were analyzed using Gompertz-Fox growth model. The study concluded that the fishing effort exceeded the economically optimal levels and there is unnecessary wastage of money, manpower and fuel in the fishing industry. The study stressed the urgent need for capture fisheries management in the State which at present follows an open access fishery where regulations exist only in the form of seasonal closure in the monsoon season
