    Response Functions to Critical Shocks in Social Sciences: An Empirical and Numerical Study

    We show that, provided one focuses on properly selected episodes, one can apply to the social sciences the same observational strategy that has proved successful in natural sciences such as astrophysics or geodynamics. For instance, in order to probe the cohesion of a policy, one can, in different countries, study the reactions to some huge and sudden exogenous shocks, which we call Dirac shocks. This approach naturally leads to the notion of structural (as opposed or complementary to temporal) forecast. Although structural predictions are by far the most common way to test theories in the natural sciences, they have been much less used in the social sciences. The Dirac shock approach opens the way to testing structural predictions in the social sciences. The examples reported here suggest that critical events are able to reveal pre-existing ``cracks'' because they probe the social cohesion which is an indicator and predictor of future evolution of the system, and in some cases foreshadows a bifurcation. We complement our empirical work with numerical simulations of the response function (``damage spreading'') to Dirac shocks in the Sznajd model of consensus build-up. We quantify the slow relaxation of the difference between perturbed and unperturbed systems, the conditions under which the consensus is modified by the shock and the large variability from one realization to another

    The Mobile Generation: Global Transformations at the Cellular Level

    Every year we see a new dimension of the ongoing Digital Revolution, which is enabling an abundance of information to move faster, cheaper, in more intelligible forms, in more directions, and across borders of every kind. The exciting new dimension on which the Aspen Institute focused its 2006 Roundtable on Information Technology was mobility, which is making the Digital Revolution ubiquitous. As of this writing, there are over two billion wireless subscribers worldwide and that number is growing rapidly. People are constantly innovating in the use of mobile technologies to allow them to be more interconnected. Almost a half century ago, Ralph Lee Smith conjured up "The Wired Nation," foretelling a world of interactive communication to and from the home that seems commonplace in developed countries today. Now we have a "Wireless World" of communications potentially connecting two billion people to each other with interactive personal communications devices. Widespead adoption of wireless handsets, the increasing use of wireless internet, and the new, on-the-go content that characterizes the new generation of users are changing behaviors in social, political and economic spheres. The devices are easy to use, pervasive and personal. The affordable cell phone has the potential to break down the barriers of poverty and accessibility previously posed by other communications devices. An entire generation that is dependant on ubiquitous mobile technologies is changing the way it works, plays and thinks. Businesses, governments, educational institutions, religious and other organizations in turn are adapting to reach out to this mobile generation via wireless technologies -- from SMS-enabled vending machines in Finland to tech-savvy priests in India willing to conduct prayers transmitted via cell phones. Cellular devices are providing developing economies with opportunities unlike any others previously available. By opening the lines of communication, previously disenfranchised groups can have access to information relating to markets, economic opportunities, jobs, and weather to name just a few. When poor village farmers from Bangladesh can auction their crops on a craigslist-type service over the mobile phone, or government officials gain instantaneous information on contagious diseases via text message, the miracles of mobile connectivity move us from luxury to necessity. And we are only in the early stages of what the mobile electronic communications will mean for mankind. We are now "The Mobile Generation." Aspen Institute Roundtable on Information Technology. To explore the implications of these phenomena, the Aspen Institute Communications and Society Program convened 27 leaders from business, academia, government and the non-profit sector to engage in three days of dialogue on related topics. Some are experts in information and communications technologies, others are leaders in the broader society affected by these innovations. Together, they examined the profound changes ahead as a result of the convergence of wireless technologies and the Internet. In the following report of the Roundtable meeting held August 1-4, 2006, J. D. Lasica, author of Darknet and co-founder of Ourmedia.org, deftly sets up, contextualizes, and captures the dialogue on the impact of the new mobility on economic models for businesses and governments, social services, economic development, and personal identity

    Responding to Cross Border Child Trafficking in South Asia: An Analysis of the Feasibility of a Technologically Enabled Missing Child Alert System

    This report examines the feasibility of a technologically enabled system to help respond to the phenomenon of cross-border child trafficking in South Asia, and makes recommendations on how to proceed with a pilot project in the selected areas of Bangladesh, Nepal and India. The study was commissioned by the Missing Child Alert (MCA) programme which is an initiative led by Plan. MCA is an initiative to address cross-border child trafficking in South Asia, led by Plan. The aim of the programme is to link existing institutions, mechanisms and resources in order to tackle the phenomenon from a regional perspective. To achieve this, Plan propose to implement a technologically equipped, institutionalised system of alert that can assist in the rescue, rehabilitation, repatriation and reintegration of children who are at risk of, or are victims of, cross-border trafficking

    Head and hands in the cloud: cooperative models for global trade to be found in traditional crafts

    Abstract: Until recent times, the standard globalization model has been to maximize profit by moving manufacture to locations where wages are low, and there are fewer obstacles, such as environmental standards. This model has been supported by a form of branding which elides the means of production, separating consumer from producer. The emergence of online trading platforms promises to bridge this gap. Both eBay and Amazon have recently created virtual stores for connecting ethical consumers with poor craft producers. Meanwhile, alternative platforms seek a similar connection in a cooperative framework, such as a Non-Government Organization (NGO), Just Change, in Bangalore. This paper compares the corporate and the cooperative models for ethical trade. From this review, it proposes a model emerging from the three-year Sangam Project that seeks to give market value to the relational practices involved in the design, production and sale of handmade craft products. The aim is to find a place for traditional craft practices otherwise displaced by globalization and urbanization. The platform presumes a three–way partnership between craftspersons, designers and consumers. Though limited primarily to gift products, it is proposed as a model for other trading practices. This paper was presented at People and the Planet 2013 at RMIT in July 201
