    With the fast growth of the Internet infrastructure and the use of large-scale complex applications in industries, transport, logistics, government, health, and businesses, there is an increasing need to design and deploy multifeatured networking applications. Important features of such applications include the capability to be self-organized, be decentralized, integrate different types of resources (personal computers, laptops, and mobile and sensor devices), and provide global, transparent, and secure access to resources. Moreover, such applications should support not only traditional forms of reliable distributing computing and optimization of resources but also various forms of collaborative activities, such as business, online learning, and social networks in an intelligent and secure environment. In this paper, we present the Juxtapose (JXTA)-Overlay, which is a JXTA-based peer-to-peer (P2P) platform designed with the aim to leverage capabilities of Java, JXTA, and P2P technologies to support distributed and collaborative systems. The platform can be used not only for efficient and reliable distributed computing but also for collaborative activities and ubiquitous computing by integrating in the platform end devices. The design of a user interface as well as security issues are also tackled. We evaluate the proposed system by experimental study and show its usefulness for massive processing computations and e-learning applications.Peer ReviewedPostprint (author's final draft

    Joint UK Land Environment Simulator (JULES) Version 2.2 User Manual

    The Joint UK Land Environment Simulator (JULES) is a computer model that simulates many soil and vegetation processes. This document describes how to run version 2.2 of JULES. It primarily describes the format of the input and output files, and does not include detailed descriptions of the science and representation of the processes in the model. The first version of JULES was based on the Met Office Surface Exchange System (MOSES), the land surface model used in the Unified Model (UM) of the UK Met Office. After that initial split, the MOSES and JULES code bases evolved separately, but with JULES2.1 these differences were reconciled, so that all versions since v2.1 have had identical code in both the standalone version (as described here) and in the UM

    It Takes More Than House Calls: Organizing to Win with a Comprehensive Union-Building Strategy

    [Excerpt] Until recently, some national and local union leaders still argued that labor should circle the wagons and take care of existing members rather than spend scarce resources on organizing nonunion workers. Today those voices have largely been silenced by the hard numbers of labor\u27s dramatic decline. As expressed in the platform of the new AFL-CIO leadership slate, the American labor movement must organize at an unprecedented pace and scale. The question unions face today is no longer whether to make organizing a priority but how that can best be achieved
