Within the field of information systems an interest in environmental issues has driven the agenda for research from green IT improvement to sustainable innovation. A challenge yet to investigate is how sustainable innovation involving a cluster of actors from multiple settings should be 1) designed and 2) orchestrated so that the innovation performed enables sustainable change. Processes for la...

Combining with agricultural production practice, we propose the agriculture wireless and humidity sensor network design, which is based on ZigBee technology. And we use the chip based on the CC2530 ZigBee protocol as the sensor nodes and coordinator nodes for data collection, transmission and display, aiming to realize the agricultural production automation and precision agriculture.

A number of fields, including genome rearrangements and interconnection network design, are concerned with sorting permutations in “as few moves as possible”, using a given set of allowed operations. These often act on just one or two segments of the permutation, e.g. by reversing one segment or exchanging two segments. The cycle graph of the permutation to sort is a fundamental tool in the the...

Choosing the scope of a plan is a fundamental question for plan makers. This question arises both in explaining plan making we observe and in justifying plan making we recommend. We frame this question from the perspective of potential participants, from the bottom up, rather than from the perspective of creating a planning process by expert judgment about scope, from the top down, such as an a...

What is the Internet like, and how do we know? Less tendentiously, how can we make general statements about the Internet without reference to alternatives that help us to understand what the space of network design possibilities might be? This paper presents a series of cases of network alternatives which provide a vantage point from which to reflect upon the ways that the Internet does or does...

Network Design problems concern the selection of arcs in a graph in order to satisfy, at minimum cost, some flow requirements, usually expressed in the form of origin-destination pair demands. Benders decomposition methods, based on the idea of partition and delayed constraint generation, have been successfully applied to many of these problems. This article presents a review of these applicati...

OBJECTIVE The primary objective was to assess the effect of family planning interventions at two health facilities in Malawi on couple years of protection (CYP). METHODS A prospective quasi-experimental design was used to compare CYP and uptake of long-acting reversible contraception (LARC) between two intervention facilities (Area 25 Health Center and Kasungu District Hospital) and two nonin...
