A Study on Evolving Optimal Cropping Patterns in Groundwater Over-exploited Region of Perambalur District of Tamil Nadu

Falling groundwater tables and depletion of economically accessible groundwater resources would have major social and economic consequences. The present study has been taken up with the overall objective of evolving optimal crop plans to sustain the use of groundwater resources for irrigation. Perambalur district was purposively selected for the study as it mainly depends on groundwater for its irrigation. Linear programming technique was used to evolve optimal crop plans. The constraints identified were primarily irrigation water, besides land availability during the cultivating seasons and capital. Six typical farms were selected, one each for the open well, wells in tank command area and tubewell-irrigated farms in critical and over-exploited groundwater regime and also for semi-critical and safe groundwater regime. The results of the optimal crop plans derived showed that the irrigation water-use in the critical period could be reduced by 24.30, 4.54 and 51.71 hours of pumping in ordinary wells, wells in tank command area and tubewell-irrigated farms, respectively in critical and over-exploited groundwater regime sample farms. In the semi-critical and safe groundwater regime sample farms, the optimal crop plans revealed that the irrigation water-use in the critical period could be reduced by 4.61, 3.99, and 4.73 hours of pumping in ordinary wells, wells in tank command area and tubewell-irrigated farms, respectively. Area under high water intensive crops namely, paddy and sugarcane declined almost in all the optimal crop plans. Area under low water intensive crops (groundnut, gingelly and tapioca) showed an increasing trend in all optimal crop plans. The net income of the sample farms increased marginally or considerably in the optimal crop plans of both the critical and overexploited groundwater regime sample farms and semi-critical and the safe groundwater regime sample farmsAgricultural and Food Policy,

Local Testing for Membership in Lattices

Motivated by the structural analogies between point lattices and linear error-correcting codes, and by the mature theory on locally testable codes, we initiate a systematic study of local testing for membership in lattices. Testing membership in lattices is also motivated in practice, by applications to integer programming, error detection in lattice-based communication, and cryptography. Apart from establishing the conceptual foundations of lattice testing, our results include the following: 1. We demonstrate upper and lower bounds on the query complexity of local testing for the well-known family of code formula lattices. Furthermore, we instantiate our results with code formula lattices constructed from Reed-Muller codes, and obtain nearly-tight bounds. 2. We show that in order to achieve low query complexity, it is sufficient to design one-sided non-adaptive canonical tests. This result is akin to, and based on an analogous result for error-correcting codes due to Ben-Sasson et al. (SIAM J. Computing 35(1) pp1-21)

A STUDY ON CUSTOMER SATISFACTION

Interest is changing the way consumer shop and buy‘s goods and services has rapidly evolved into global phenomenon many companies have started using the interest is the aim of cutting marketing cost their by reducing the price of the products and services in order to stay ahead in highly competitive markets. Companies also use the interest to convey communicate and disseminate information to sell the product obtain the feedback and also to conduct satisfaction surveys with thecustomers

A STUDY ON EMPLOYEE WELFARE MEASURES

The present study was conducted and aims at analysing the strengths and weakness of the welfare activities in THE RAMCO CEMENTS LIMITED ATALATHIYUR. The percentage of success that each and every individual employees obtained is very essential in determining the organisational effectiveness. This is to know the assessment of how employees succeed in meeting their goals and managing their works in the organisation. This present study was made and aims at knowing “welfare system”. In this project the data and information has provided by the organisation and made a survey from the staffs of the organisation. The sample size is 50 among 78 staffs. The data is collected through issuing questionnaire to the employees. Through the statistical tool correlation, the data were analysed and tabulated and also interpretations were given below the tabulation. Finally findings, suggestions and conclusion are also given in this report. This leads to the topic of employee welfare measures

A STUDY ON THE BURNOUT LEVEL AMONG THE EMPLOYEES AT NEST CYBER CAMPUS BANGALORE

Burnout is basically a stress induced problem prevalent among helping professionals like social-workers, nursing staff, employee-relations executives, teachers and law enforcing functionaries. People in helping profession like doctors, counselors, police officers and nurses also have greater probabilities of burnout (Maslach 1982). Burnout does not occur suddenly but begins with small warning signals and most of the time one can not pin point the exact cause. As said by Lee and Ashforth (1988) through their longitudinal study on supervisors and managers, burnouts develop on phases

A STUDY ON JOB SATISFACTIION

Job satisfaction is the widely discussed issues in organizational behavior, personnel and human resource management and organizational management. As job does require a great deal of thoroughness and commitment, so in job it is more important to have mental commitment and loyalty than physical presence. In this study the researcher investigated the present level of job satisfaction among the employee of engineering industry based on a survey. The study reveals the level of job satisfaction in ACCOUSTICS INDIA PRIVATE LIMITED. IT overall views of the job satisfaction explaining the needs and importance of the satisfied. The purpose of the study is proved suggestions to increase the satisfaction level of employees. Form the study it is clear that most of the employees are satisfied with the existing policies of the company and also the organizations have to find out the problems of each and every employee
