Statistical designs, sample surveys and evaluation designs are fundamental tools for solving queries related to population parameters and the effects of public programs and policies. This book explores the concepts of effective sampling and evaluation techniques in a cohesive and concise manner. Sampling design techniques, including simple random sampling, stratified sampling, systematic sampling and cluster sampling, are presented in detail. These techniques play a vital role when choosing an appropriate sample survey design. The concepts of multistage design, non-sampling errors and evaluation techniques including before-after design, one-time treatment and control design are discussed extensively. The book focuses on different methods of estimation, including multiple regression analysis and logistic regression. It covers the issue of bias in a design, the source of such bias and ways to overcome it. Clear guidelines with remedial measures are outlined to facilitate choosing a suitable sampling design.
Over the last decade, commodity derivatives trading in India has undergone a significant growth, and has surpassed equity derivatives trading. The book covers almost the entire spectrum of commodities traded in the Indian commodity market, including agricultural commodities, crude oil, base metal, precious metal, electricity, carbon, weather, freight, real estate, and water. A distinguishing feature of the book is that it lucidly explains the peculiarities of various commodities, delving into their technical and historical details. As commodity market in a country cannot function in isolation, commodity contracts traded in other international exchanges, like LME, CME, The Baltic Exchange, Nordpool, etc. have also been discussed in detail. Commodity derivatives contracts, such as futures, FRAs, options, Tapos, swaps, spreads (crush, crack, dark and spark), collars, ETFs, Contract for Differences (CfDs) and cool bonds, etc. have been discussed extensively in the book. Fundamental factors associated with different types of commodities have been dealt with to develop a deeper understanding of the peculiarities associated with various commodities. This book documents the case studies involving important commodity price manipulations and frauds in commodity derivatives trading. These have been analyzed to bring out the necessity and the role of the commodity market regulators in maintaining market integrity. Major commodity derivatives trading losses that have shaken up even some prominent companies all over the world have been discussed to highlight the risks associated with commodity derivatives trading. The book is intended for the postgraduate students of Management. It is equally beneficial for the students and professionals opting for Diploma courses in Banking and Finance.• Around 40 Business Snapshots have been presented at appropriate sections in the book, so that a reader can apply the concepts to real-life situations/happenings. • Around 100 Numerical Examples have also been worked in various chapters to help the reader develop a deeper understanding of the underlying theories. • Worked out examples and business snapshots have been provided in large numbers. • End of the chapter questions have been provided for the students to test their understanding. • Power Point slides available online at www.phindia.com/prabinarajib to provide integrated learning to the students.
Urban Disasters and Resilience in Asia presents the latest information on the intensity and frequency of disasters. Specifically, the fact that, in urban areas, more than 50% of the world's population is living on just 2% of the land surface, with most of these cities located in Asia and developing countries that have high vulnerability and intensification. The book offers an in-depth and multidisciplinary approach to reducing the impact of disasters by examining specific evidence from events in these areas that can be used to develop best practices and increase urban resilience worldwide. As urban resilience is largely a function of resilient and resourceful citizens, building cities which are more resilient internally and externally can lead to more productive economic returns. In an era of rapid urbanization and increasing disaster risks and vulnerabilities in Asian cities, Urban Disasters and Resilience in Asia is an invaluable tool for policy makers, researchers, and practitioners working in both public and private sectors. - Explores a broad range of aspects of disaster and urban resiliency, including environmental, economic, architectural, and engineering factors - Bridges the gap between urban resilience and rural areas and community building - Provides evidence-based data that can lead to improved disaster resiliency in urban Asia - Focuses on Asian cities, some of the most densely populated areas on the planet, where disasters are particularly devastating
