In Uttar Pradesh, a new tradition has been started of selecting B.Ed degree holders for a job in Primary Schools and it has been named "Vishisht BTC". Applying their own logic, the ruling governments use variuos criterion to select the candidates. The basic problem is that they have to choose candidates on the basis of merit of their marks in various exams. Now, it is well-established fact that marking is not similar in all universities/colleges. So for a same exam, there can be much inter-university as well as intra-university variation in marks given to students. The point is that student …
Factors Influencing Farmers’ Willingness To Protect Groundwater From Nonpoint Sources Of Pollution In The Lower Bhavani River Basin, Tamil Nadu, India, Sacchidananda Mukherjee
Factors Influencing Farmers’ Willingness To Protect Groundwater From Nonpoint Sources Of Pollution In The Lower Bhavani River Basin, Tamil Nadu, India, Sacchidananda Mukherjee

Farmers' perceptions about groundwater and drinking water quality are important, which influence their willingness to adopt protection measures either individually or collectively. This study attempts to capture the factors influencing farmers’ perceptions and their willingness to protect groundwater from nonpoint sources of pollution, and their willingness to support the local government to supply drinking water through alternative arrangements. Six villages are identified in the Lower Bhavani River Basin, Tamil Nadu, India on the basis of their long-term groundwater nitrate concentrations and sources of irrigation. A pre-structured questionnaire survey (face-to-face interviews) has been administered to 395 farm-households across six villages during …

Bayesian Identification, Selection And Estimation Of Functions In High-Dimensional Additive Models, Anastasios Panagiotelis, Michael Smith

In this paper we propose an approach to both estimate and select unknown smooth functions in an additive model with potentially many functions. Each function is written as a linear combination of basis terms, with coefficients regularized by a proper linearly constrained Gaussian prior. Given any potentially rank deficient prior precision matrix, we show how to derive linear constraints so that the corresponding effect is identified in the additive model. This allows for the use of a wide range of bases and precision matrices in priors for regularization. By introducing indicator variables, each constrained Gaussian prior is augmented with a …
Bayesian Density Forecasting Of Intraday Electricity Prices Using Multivariate Skew T Distributions, Anastasios Panagiotelis, Michael Smith
Bayesian Density Forecasting Of Intraday Electricity Prices Using Multivariate Skew T Distributions, Anastasios Panagiotelis, Michael Smith
Michael Stanley Smith
Electricity spot prices exhibit strong time series properties, including substantial periodicity, both inter-day and intraday serial correlation, heavy tails and skewness. In this paper we capture these characteristics using a first order vector autoregressive model with exogenous effects and a skew t distributed disturbance. The vector is longitudinal, in that it comprises observations on the spot price at intervals during a day. A band two inverse scale matrix is employed for the disturbance, as well as a sparse autoregressive coefficient matrix. This corresponds to a parsimonious dependency structure that directly relates an observation to the two immediately prior, and the …
