Over the next decade, most devices connected to the Internet will not be used by people in the familiar way that personal computers, tablets and smart phones are. Billions of interconnected devices will be monitoring the environment, transportation systems, factories, farms, forests, utilities, soil and weather conditions, oceans and resources.§Many of these sensors and actuators will be networked into autonomous sets, with much of the information being exchanged machine-to-machine directly and without human involvement. Machine-to-machine communications are typically terse. Most sensors and actuators will report or act upon small pieces of information - "chirps". Burdening these devices with current network protocol stacks is inefficient, unnecessary and unduly increases their cost of ownership. §This must change. The architecture of the§Internet of Things must evolve now by§incorporating simpler protocols toward at the edges of the§network, or remain forever inefficient. Rethinking the Internet of Things describes reasons why we must rethink current approaches to the Internet of Things. Appropriate architectures that will coexist with existing networking protocols are described in detail. An architecture comprised of integrator functions, propagator nodes, and end devices, along with their interactions, is explored. §

Making Nature, Shaping Culture University of Nebraska Press

For ages, farmers have domesticated plant varieties, while scientists have "made" nature through hybridization and other processes. This give and take - mediated through negotiations, persuasion, the marketplace, and even coercion - has resulted in what we call "nature" and has led to a homogenization of plant crops. Yet homogenization has led to new problems: genetic vulnerability, and the lack of systems to maintain plant germplasm of varieties no longer grown in the fields. This book addresses issues previously viewed as primarily technical concerning the germplasm debate: that is, how, what, and where to store the range of genetic materials necessary to reproduce plants. By examining Brazil, Chile, France, and the United States, the authors show how different cultures respond to the decline in genetic diversity. The findings show that the quest for uniformity in foods, agriculture, and environment eventually threatens everyone. The politicization of this debate is inevitable because the destruction of human cultural diversity goes hand in hand with the destruction of plant varietal diversity. The authors agree that responses to the controversies must involve food security, relinking of food with agriculture and the environment, revaluing traditional knowledge, and rethinking development. They stress that answers will be found not by experts acting unilaterally but through the democratization of scientific and technical exchange.
