“…. .Although the census covers the entire population, it fails to provide information on shortterm and temporary migration (Bhagat and Mohanty, 2009;Kundu, 2009;Skeldon, 2002)." Thus, most studies rely on sample studies conducted by the National Sample Survey.…”

This article examines the patterns and trends in inter‐State migration across the Indian States and observes that along with the demographic factors, migration is also affected by the fiscal profile of States. Controlling for the economic prosperity of States as reflected in their per capita Net State Domestic Product and the nature of fiscal policy stance, econometric estimation using the gravity model suggests that level of vertical federal transfers and its horizontal distribution is an important determinant of the pattern of inter State migration. To correct for the extant horizontal fiscal inequality across the Indian States, the article suggests a relatively more progressive transfer system and a developmental fiscal policy stance at the State level to reduce the pressure of out‐migration to prosperous regions of the country.

The work presented in this thesis concerns the development of a value driven engineering design assessment framework and its application to the conceptual design of an Unmanned Air System (UAS) to be utilised in a defence application. This research demonstrates the implementation of the value driven design philosophy in this framework, identifying value enhancing designs, with value not converted to monetary worth and as perceived by all stakeholders involved. A multi-criteria and multi-stakeholder decision making analysis is adopted to address their preferences as well as to study their interacting strategic choices. The ultimate objective of this framework is to convert engineering design to a decision making analysis with multiple conflicting objectives of multiple stakeholders considered.This framework is capable of providing a product definition and estimation of all performance and cost related attributes for the conceptual phase. However, instead of pertaining to a single aircraft concept, a broad range of combinations of UAS configurations and geometries is generated by systematically searching alternative concepts and design configurations through a novel parameterization of the aircraft geometric topologies.Value, related to the designed system's capabilities or performance and lifecycle cost, is used to compare different alternatives in the decision making of engineering design through the appropriate value model. Following a valuefocused approach, a novel multi-attribute value model is introduced for objectively capturing the stakeholder's preferences and expectations. Furthermore, a more sophisticated multi-attribute utility model, based on standard Multi-attribute Utility Theory, is employed in the evaluation.Game Theory as an optimization tool is used to develop a novel hybrid cooperative/non-cooperative non-zero sum, complete information game among all involved stakeholders as players. This game successfully addresses the stakeholders' preferences in a functional outcome-focused way, resolving the high indeterminacy of the alternative designs through a cooperative game. At the same time, their strategic interactions are captured in a process-focused non-cooperative game. Hence, the optimal design is identified through the simultaneous employment of the Nash bargaining solution and the Nash equilibrium.i

An ecodesign guideline tool for the aviation industry has been developed in the project Clean Sky. Following the targets of the Advisory Council for Aeronautical Research in Europe (ACARE), aircraft specific life cycle assessment data of different materials and material combinations were collected and implemented in an easy to handle database tool. The tool thereby provides a third robust basis for decision making in addition to costs and weight. The tool is focused on the end of life phase of a product, in particularly economic feasibility, separation and recycling processes
