By synthesizing prominent literature that is peripherally related, this paper establishes both a base of knowledge for this new realm of inquiry, as well as identifying a platform for further research. The paper also adds to the knowledge based by creating a theoretical framework which brings together practice theory with situationist theory to present a new lens through which to examine this issue. From a theoretical standpoint, technology is said to be a reflection of society. If technology can be linked to society and society in turn can be equated with the spectacle then it is a natural progression to examine technology as spectacle. Therefore, using the two theories in tandem provides a very suitable lens to frame an investigation of technology as spectacle, and the viability of social media as a communication tool for special events.展开更多

The objective of this work was to evaluate the effects in field controlled episodic drought conditions on cotton gas exchange. Irrigated cotton was subjected to water stress at different timings. Irrigation was interrupted at the squaring stage, early flowering stage, from three weeks at peak bloom, and from peak bloom to the crop termination. These episodic drought treatments were compared with cotton fully irrigated throughout the whole season. From 2010 to 2012, cotton cultivar FM9180 gas exchange was measured throughout the season using a LiCor-6400 portable photosynthesis system. In 2011 and 2012, measurements were also made on DP0935 cultivar. The cotton physiological parameters evaluated included photosynthesis, transpiration and temperature. From the several parameters evaluated, some relationships were presented. Episodic drought periods can affect leaf-level gas exchange and impact yield. Photosynthesis and yield were particularly sensitive to water deficit at early flowering. Despite an increase in leaf water use efficiency under water deficit, overall growth and yield were inhibited in all treatments with a stress component. Understanding the relative sensitivity at different growth stages can help with irrigation decisions when water resources are limited.展开更多

Professional rescue and emergency forces, including medical services, are the ＂Golden Stan- dard＂ of emergency management systems. Regulative laws, proper organization of resources, equipment, training and adequate delivery of medical measures are key factors in systematic approaches to manage emergencies and disasters alike and thus save lives. During disasters command, communication, coor- dination and cooperation are essential to cope with extreme situations, even more so in a globalized world. In this article, we describe the major historical milestones, the current state of the German system in emergency and disaster management and its integration into the broader European approach.展开更多
