Fiber-Based Laser Transmitter at 1.57 Micrometers for Remote Sensing of Atmospheric Carbon Dioxide from Satellites

Over the past 20 years, NASA Goddard has successfully developed space-based lidar for remote sensing studies of the Earth and planets. The lidar in all missions to date have used diode pumped Nd:YAG laser transmitters. Recently we have been concentrating work on developing integrated path differential absorption (IPDA) lidar to measure greenhouse gases, with the goal of measurements from space. Due to the absorption spectrum of CO2 a fiber-based master oscillator power amplifier (MOPA) laser with a tunable seed source is an attractive laser choice. Fiber-based lasers offer a number of potential advantages for space, but since they are relatively new, challenges exist in developing them. In order to reduce risks for new missions using fiber-based lasers, we developed a 30- month plan to mature the technology of a candidate laser transmitter for space-based CO2 measurements to TRL-6. This work is also intended to reduce development time and costs and increase confidence in future mission success

The Emergence and Development of Association Football: Influential Sociocultural Factors in Victorian Birmingham

This article explores the interdependent, complex sociocultural factors that facilitated the emergence and diffusion of football in Birmingham. The focus is the development of football in the city, against the backdrop of the numerous social changes in Victorian Birmingham. The aim is to fill a gap in the existing literature which seemingly overlooked Birmingham as a significant footballing centre, and the ‘ordinary and everyday’ aspects of the game’s early progression. Among other aspects, particular heed is paid to the working classes’ involvement in football, as previous literature has often focused on the middle classes and their influence on and participation in organized sport. As the agency of the working classes along with their mass participation and central role in the game’s development is unfolded, it is argued that far from being passive cultural beings, the working classes, from the beginnings, actively negotiated the development of their own emergent football culture

Sport, peacemaking and conflict resolution: a contextual analysis and modelling of the sport, development and peace sector

International audienceIn recent years, a wide variety of organizations (notably the UN and nongovernmental ones) have used sport as an interventionist tool to nurture peacemaking across divided communities. This paper examines and theorizes these peacemaking initiatives across the expanding 'sport, development and peace' (SDP) sector. I begin by locating SDP projects within their historical contexts, and as significant elements within the emerging 'global civil society'. I then set out three ideal-type models of SDP project; namely, the 'technical', 'dialogical', and 'critical'. Each model is examined through a set of common social heuristics, such as its core objectives and paradigmatic methods. The models may be employed to analyze other peacemaking and development fields. The first two models are most influential among existing SDP projects; the potential benefits of the 'critical' model are also outlined

Crown of Self-Sacrifice: A Self-Sacrificial Elite in the Age of the New Imperialism

Edward Palmer Thompson’s The Making of the English Working Class (1963) is widely known throughout the academic world–and indeed beyond. Justifiably. It has many virtues. Among other things, it is an impressive synthesis of the ideas of the “good and the great” of the social sciences. In it we hear echoes not only of Gramsci but of Weber and Durkheim, and we see references not only to classes but to codes and values (Alexander 1990: 21). Thompson, of course, was concerned, first and foremost,..
