Out of Nowhere: The 'emergence' of spacetime in string theory
This is a chapter of the planned monograph "Out of Nowhere: The Emergence of
Spacetime in Quantum Theories of Gravity", co-authored by Nick Huggett and
Christian W\"uthrich and under contract with Oxford University Press. (More
information at www.beyondspacetime.net.) This chapter analyses the nature and
derivation of spacetime topology and geometry according to string theory.Comment: 40 pages, 2 figure
Out of Nowhere: Spacetime from causality: causal set theory
This is a chapter of the planned monograph "Out of Nowhere: The Emergence of
Spacetime in Quantum Theories of Gravity", co-authored by Nick Huggett and
Christian W\"uthrich and under contract with Oxford University Press. (More
information at www.beyondspacetime.net.) This chapter introduces causal set
theory and identifies and articulates a 'problem of space' in this theory.Comment: 29 pages, 5 figure

Risk management in agriculture
This monograph was written to be part of the series of studies commissioned by the Ministry of Agriculture under the rubric of "State of Indian Farmer - A Millennium Study". On the basis of existing literature, this study documents the status of our knowledge on risks of agriculture and their management. Chapter 2 discusses the evidence on the nature, type and magnitude of agricultural risks. Chapter 3 discusses farmer strategies to combat risk. In addition to the mechanisms at the level of the farm household, the need to cope with risk can also affect community interactions and social customs. This is examined in Chapter 4. In chapter 5, we consider how production risks have been transformed by developments in the agricultural economy in the post-independence period. In chapter 6, we review the principal developments that have impacted on market risks.
High-Energy Aspects of Solar Flares: Overview of the Volume
In this introductory chapter, we provide a brief summary of the successes and
remaining challenges in understanding the solar flare phenomenon and its
attendant implications for particle acceleration mechanisms in astrophysical
plasmas. We also provide a brief overview of the contents of the other chapters
in this volume, with particular reference to the well-observed flare of 2002
July 23Comment: This is the introductory article for a monograph on the physics of
solar flares, inspired by RHESSI observations. The individual articles are to
appear in Space Science Reviews (2011
