    Open education: common(s), commonism and the new common wealth

    Get PDF
    Open Education, and specifically the Open Education Resources movement, seeks to provide universal access to knowledge, undermining the historical enclosure and increasing privatisation of the public education system. An important aspect of this movement is a reinvigoration of the concept of ‘the commons’. The paper examines this aspiration by submitting the implicit theoretical assumptions of Open Education and the underlying notion of ‘the commons’ to the test of critical political economy. The paper acknowledges the radical possibility of the idea of ‘the commons’, but argues that its radical potentiality can be undermined by a preoccupation with ‘the freedom of things rather than with the freedom of labour’. The paper presents an interpretation of ‘the commons’ based on the concept of ‘living knowledge’ and ‘autonomous institutionality’ (Roggero, 2011), and offers the Social Science Centre in the UK, as an example of an ‘institution of the common’1. The paper concludes by arguing the most radical revision of the concept of ‘the common’ involves a fundamental reappraisal of what constitutes social or common wealth

    A Relational Event Approach to Modeling Behavioral Dynamics

    Full text link
    This chapter provides an introduction to the analysis of relational event data (i.e., actions, interactions, or other events involving multiple actors that occur over time) within the R/statnet platform. We begin by reviewing the basics of relational event modeling, with an emphasis on models with piecewise constant hazards. We then discuss estimation for dyadic and more general relational event models using the relevent package, with an emphasis on hands-on applications of the methods and interpretation of results. Statnet is a collection of packages for the R statistical computing system that supports the representation, manipulation, visualization, modeling, simulation, and analysis of relational data. Statnet packages are contributed by a team of volunteer developers, and are made freely available under the GNU Public License. These packages are written for the R statistical computing environment, and can be used with any computing platform that supports R (including Windows, Linux, and Mac).

    A market based approach for resolving resource constrained task allocation problems in a software development process

    Get PDF
    We consider software development as an economic activity, where goods and services can be modeled as a resource constrained task allocation problem. This paper introduces a market based mechanism to overcome task allocation issues in a software development process. It proposes a mechanism with a prescribed set of rules, where valuation is based on the behaviors of stakeholders such as biding for a task. A bid process ensures that a stakeholder, who values the resource most, will have it allocated for a limited number of times. To observe the bidders behaviors, we initiate an approach incorporated with a process simulation model. Our preliminary results support the idea that our model is useful for optimizing the value based task allocations, creating a market value for the project assets, and for achieving proper allocation of project resources specifically on large scale software projects

    GraphCombEx: A Software Tool for Exploration of Combinatorial Optimisation Properties of Large Graphs

    Full text link
    We present a prototype of a software tool for exploration of multiple combinatorial optimisation problems in large real-world and synthetic complex networks. Our tool, called GraphCombEx (an acronym of Graph Combinatorial Explorer), provides a unified framework for scalable computation and presentation of high-quality suboptimal solutions and bounds for a number of widely studied combinatorial optimisation problems. Efficient representation and applicability to large-scale graphs and complex networks are particularly considered in its design. The problems currently supported include maximum clique, graph colouring, maximum independent set, minimum vertex clique covering, minimum dominating set, as well as the longest simple cycle problem. Suboptimal solutions and intervals for optimal objective values are estimated using scalable heuristics. The tool is designed with extensibility in mind, with the view of further problems and both new fast and high-performance heuristics to be added in the future. GraphCombEx has already been successfully used as a support tool in a number of recent research studies using combinatorial optimisation to analyse complex networks, indicating its promise as a research software tool

    Online Store Locator: An Essential Resource for Retailers in the 21st Century

    Get PDF
    Most retailers use their websites and social media to increase their visibility, while potential customers get information about these retailers using the Internet on electronic devices. Many papers have previously studied online marketing strategies used by retailers, but little attention has been paid to determine how these companies provide information through the Internet about the location and characteristics of their stores. This paper aims to obtain evidence about the inclusion of interactive web maps on retailers’ websites to provide information about the location of their stores. With this purpose, the store locator interactive tools of specialty retailers’ websites included in the report “Global Powers of Retailing 2015” are studied in detail using different procedures, such as frequency analysis and word clouds. From the results obtained, it was concluded that most of these firms use interactive maps to provide information about their offline stores, but today some of them still use non-interactive (static) maps or text format to present this information. Moreover, some differences were observed among the search filters used in the store locator services, according to the retailer’s specialty. These results provided insight into the important role of online store locator tools on retailers’ websites
