How insights from the social sciences, including social psychology and economics, can improve the design of online communities.Online communities are among the most popular destinations on the Internet, but not all online communities are equally successful. For every flourishing Facebook, there is a moribund Friendster―not to mention the scores of smaller social networking sites that never attracted enough members to be viable. This book offers lessons from theory and empirical research in the social sciences that can help improve the design of online communities.The authors draw on the literature in psychology, economics, and other social sciences, as well as their own research, translating general findings into useful design claims. They explain, for example, how to encourage information contributions based on the theory of public goods, and how to build members' commitment based on theories of interpersonal bond formation. For each design claim, they offer supporting evidence from theory, experiments, or observational studies.

A report on development economics in action, by a crucial player in Nigeria's recent reforms.Corrupt, mismanaged, and seemingly hopeless: that's how the international community viewed Nigeria in the early 2000s. Then Nigeria implemented a sweeping set of economic and political changes and began to reform the unreformable. This book tells the story of how a dedicated and politically committed team of reformers set out to fix a series of broken institutions, and in the process repositioned Nigeria's economy in ways that helped create a more diversified springboard for steadier long-term growth. The author, Harvard- and MIT-trained economist Ngozi Okonjo-Iweala, currently Nigeria's Coordinating Minister for the Economy and Minister of Finance and formerly Managing Director of the World Bank, played a crucial part in her country's economic reforms. In Nigeria's Debt Management Office, and later as Minister of Finance, she spearheaded negotiations with the Paris Club that led to the wiping out of $30 billion of Nigeria's external debt, 60 percent of which was outright cancellation. Reforming the Unreformable offers an insider's view of those debt negotiations; it also details the fight against corruption and the struggle to implement a series of macroeconomic and structural reforms. This story of development economics in action, written from the front lines of economic reform in Africa, offers a unique perspective on the complex and uncertain global economic environment.

A proposal for using cost-benefit analysis to evaluate the socioeconomic impact of public investment in large scientific projects.Large particle accelerators, outer space probes, genomics platforms: all are scientific enterprises managed through the new form of the research infrastructure, in which communities of scientists collaborate across nations, universities, research institutions, and disciplines. Such large projects are often publicly funded, with no accepted way to measure the benefits to society of these investments. In this book, Massimo Florio suggests the use of cost-benefit analysis (CBA) to evaluate the socioeconomic impact of public investment in large and costly scientific projects.The core concept of CBA of any infrastructure is to undertake the consistent intertemporal accounting of social welfare effects using the available information. Florio develops a simple framework for such accounting in the research infrastructure context and then offers a systematic analysis of the benefits in terms of the social agents involved. He measures the benefits to scientists, students, and postdoctoral researchers; the effect on firms of knowledge spillovers; the benefits to users of information technology and science-based innovation; the welfare effects on the general public of cultural services provided by RIs; and the willingness of taxpayers to fund scientific knowledge creation. Finally, Florio shows how these costs and benefits can be expressed in the form of stochastic net present value and other summary indicators.

More than 140 illustrated biographical profiles map the innovative modern California design community.Mid-twentieth-century California offered fertile ground for design innovations. The state's reputation as a land of unlimited opportunity, its many institutions of higher learning, and its perpetually booming population created conditions that allowed designers and craftspeople to flourish. They found an eager market among educated and newly affluent Californians, and their products shaped the material culture of the entire nation. This book, a companion to the popular 2011 MIT Press/LACMA publication California Design, 1930–1965: “Living in a Modern Way,” reveals the complex web of influences, collaborations, institutional affiliations, and social networks that fueled the California design economy.This book offers more than 140 illustrated biographical profiles of the most significant mid-century California designers, including such famous names as Saul Bass and Charles and Ray Eames as well as many lesser known but influential practitioners. These designers, craftspeople, and manufacturers worked in the full range of design media, creating furniture, fashion, textiles, jewelry, ceramics, and graphic and industrial design. Each entry includes a succinct biography, a portrait of the designer or image of an important design, cross-references to other entries, and a list of sources for further research. Significant examples of California design and craft objects are featured in more than 180 illustrations and rare photographs.Created by internationally renowned graphic designer Irma Boom, the book is a beautifully crafted object in its own right. It will become an indispensable resource for all those interested in modern design.
