The present study examines the relationship of firm's size and profitability, taking into consideration major characteristics such as size and profitability of 20 Indian Automobile Companies for a period of 13 years that is, from 1996-97 to 2008-09, Hypothesis is developed taking into account both previous research and particular idiosyncrasies of the national context. The study employed three model specifications in order to test the hypothesis, using the short-term and long-term measures of profitability. The empirical findings suggest that firm's size emerges as an important factor affecting profitability. The results show mixed evidence; firm's size is positively significant in Commercial Vehicles and Passenger Cars & Multi-utility Vehicles sector and negatively significant in Two and Three Wheelers sector and the Whole Industry. The study concludes that the validity and the generalisation of the findings are pending future research in other industries or sectors that ratifies or refutes them.

The blockchain is an incorruptible digital ledger of economic transactions that can be programmed to record not just financial transactions but virtually everything of value. Blockchain technology makes breakthroughs in business intelligence in many areas such as banking sector, finance, judiciary, commerce, and information technology. Web service compositions have a revolutionary impact on business intelligence by enabling loose coupling, data consolidation from diverse sources, consolidation of information under a single roof, easing ad-hoc querying and reporting. The objective of current work is to investigate the applicability of blockchain for the semantic web service composition process. The paper focuses on design of conceptual architecture and the algorithm for QoS-aware semantic web service composition (SWSC) using blockchain.
