Gurus, hired guns, and warm bodies
Over the last several decades, employers have increasingly replaced permanent employees with temporary workers and independent contractors to cut labor costs and enhance flexibility. Although commentators have focused largely on low-wage temporary work, the use of skilled contractors has also grown exponentially, especially in high-technology areas. Yet almost nothing is known about contracting or about the people who do it. This book seeks to break the silence.

STEM the Tide
Proven strategies for reforming STEM education in America's schools, colleges, and universities.
One study after another shows American students ranking behind their international counterparts in the STEM fields—science, technology, engineering, and math. Businesspeople and cultural critics such as Bill Gates warn that this alarming situation puts the United States at a serious disadvantage in the high-tech global marketplace of the twenty-first century, and President Obama places improvement in these areas at the center of his educational reform. What can be done to reverse this poor performance and to unleash America's wasted talent?
David E. Drew has good news—and the tools America needs to keep competitive. Drawing on both academic literature and his own rich experience, Drew identifies proven strategies for reforming America's schools, colleges, and universities, and his comprehensive review of STEM education in the United States offers a positive blueprint for the future. These research-based strategies include creative and successful methods for building strong programs in science and mathematics education and show how the achievement gap between majority and minority students can be closed. A crucial measure, he argues, is recruiting, educating, supporting, and respecting America's teachers.
Accessible, engaging, and hard hitting, STEM the Tide is a clarion call to policymakers, administrators, educators, and everyone else concerned about students' participation in the STEM fields and America's competitive global position.

The Metaverse as a Virtual Form of Smart Cities: Opportunities and Challenges for Environmental, Economic, and Social Sustainability in Urban Futures
Data infrastructures, economic processes, and governance models of digital platforms are increasingly pervading urban sectors and spheres of urban life. This phenomenon is known as platformization, which has in turn given rise to the phenomena of platform society, where platforms have permeated the core of urban societies. A recent manifestation of platformization is the Metaverse, a global platform project launched by Meta (formerly Facebook) as a globally operating platform company. The Metaverse represents an idea of a hypothetical “parallel virtual world” that incarnate ways of living and working in virtual cities as an alternative to smart cities of the future. Indeed, with emerging innovative technologies—such as Artificial Intelligence, Big Data, the IoT, and Digital Twins—providing rich datasets and advanced computational understandings of human behavior, the Metaverse has the potential to redefine city designing activities and service provisioning towards increasing urban efficiencies, accountabilities, and quality performance. However, there still remain ethical, human, social, and cultural concerns as to the Metaverse’s influence upon the quality of human social interactions and its prospective scope in reconstructing the quality of urban life. This paper undertakes an upper-level literature review of the area of the Metaverse from a broader perspective. Further, it maps the emerging products and services of the Metaverse, and explores their potential contributions to smart cities with respect to their virtual incarnation, with a particular focus on the environmental, economic, and social goals of sustainability. This study may help urban policy makers to better understand the opportunities and implications of the Metaverse upon tech-mediated practices and applied urban agendas, as well as assess the positives and negatives of this techno-urban vision. This paper also offers thoughts regarding the argument that the Metaverse has disruptive and substantive effects on forms of reconstructing reality in an increasingly platformized urban society. This will hopefully stimulate prospective research and further critical perspectives on the topic.

Outbreak dynamics of COVID-19 in China and the United States
On March 11, 2020, the World Health Organization declared the coronavirus disease 2019, COVID-19, a global pandemic. In an unprecedented collective effort, massive amounts of data are now being collected worldwide to estimate the immediate and long-term impact of this pandemic on the health system and the global economy. However, the precise timeline of the disease, its transmissibility, and the effect of mitigation strategies remain incompletely understood. Here we integrate a global network model with a local epidemic SEIR model to quantify the outbreak dynamics of COVID-19 in China and the United States. For the outbreak in China, in n=30 provinces, we found a latent period of 2.56 ± 0.72 days, a contact period of 1.47 ± 0.32 days, and an infectious period of 17.82 ± 2.95 days. We postulate that the latent and infectious periods are disease-specific, whereas the contact period is behavior-specific and can vary between different provinces, states, or countries. For the early stages of the outbreak in the United States, in n=50 states, we adopted the disease-specific values from China and found a contact period of 3.38 ± 0.69 days. Our network model predicts that—without the massive political mitigation strategies that are in place today—the United States would have faced a basic reproduction number of 5.30 ± 0.95 and a nationwide peak of the outbreak on May 10, 2020 with 3 million infections. Our results demonstrate how mathematical modeling can help estimate outbreak dynamics and provide decision guidelines for successful outbreak control. We anticipate that our model will become a valuable tool to estimate the potential of vaccination and quantify the effect of relaxing political measures including total lockdown, shelter in place, and travel restrictions for low-risk subgroups of the population or for the population as a whole.

Hurdles and Opportunities for Landscape-Scale Restoration
Gaps in knowledge must be identified, capacities developed, and research translated into policy and practice. A priority outcome from the 2012 United Nations Rio+20 Conference on Sustainable Development ( 1 ) was the target to restore, by 2020, 150 million ha of disturbed and degraded land globally ( 2 ). An initiative of this scale is estimated to cost U.S.$18 billion per year and to provide U.S. $ 84 billion per year to the global economy ( 2 ). Although such initiatives have transformative potential because of their scope and backing, they require technology and knowledge capacity to deliver proven, scalable restoration ( 3 ). Restoration processes must achieve the greatest value for money, as far as socioeconomic and biodiversity conservation outcomes, while avoiding costly and simplistic plantings ( 4 ).

Life as Surplus
Focusing on the period between the 1970s and the present, Life as Surplus is a pointed and important study of the relationship between politics, economics, science, and cultural values in the United States today. Melinda Cooper demonstrates that the history of biotechnology cannot be understood without taking into account the simultaneous rise of neoliberalism as a political force and an economic policy. From the development of recombinant DNA technology in the 1970s to the second Bush administration's policies on stem cell research, Cooper connects the utopian polemic of free-market capitalism with growing internal contradictions of the commercialized life sciences.
The biotech revolution relocated economic production at the genetic, microbial, and cellular level. Taking as her point of departure the assumption that life has been drawn into the circuits of value creation, Cooper underscores the relations between scientific, economic, political, and social practices. In penetrating analyses of Reagan-era science policy, the militarization of the life sciences, HIV politics, pharmaceutical imperialism, tissue engineering, stem cell science, and the pro-life movement, the author examines the speculative impulses that have animated the growth of the bioeconomy.
At the very core of the new post-industrial economy is the transformation of biological life into surplus value. Life as Surplus offers a clear assessment of both the transformative, therapeutic dimensions of the contemporary life sciences and the violence, obligation, and debt servitude crystallizing around the emerging bioeconomy.

Innovation Economics
This important book delivers a critical wake-up call: a fierce global race for innovation advantage is under way, and while other nations are making support for technology and innovation a central tenet of their economic strategies and policies, America lacks a robust innovation policy. What does this portend? Robert Atkinson and Stephen Ezell, widely respected economic thinkers, report on profound new forces that are shaping the global economy-forces that favor nations with innovation-based economies and innovation policies. Unless the United States enacts public policies to reflect this reality, Americans face the relatively lower standards of living associated with a noncompetitive national economy.
The authors explore how a weak innovation economy not only contributed to the Great Recession but is delaying America's recovery from it and how innovation in the United States compares with that in other developed and developing nations. Atkinson and Ezell then lay out a detailed, pragmatic road map for America to regain its global innovation advantage by 2020, as well as maximize the global supply of innovation and promote sustainable globalization.

Digital government
Few developments have had broader consequences for the public sector than the introduction of the Internet and digital technology. In this book, Darrell West discusses how new technology is altering governmental performance, the political process, and democracy itself by improving government responsiveness and increasing information available to citizens.
Using multiple methods--case studies, content analysis of over 17,000 government Web sites, public and bureaucrat opinion survey data, an e-mail responsiveness test, budget data, and aggregate analysis--the author presents the most comprehensive study of electronic government ever undertaken. Among other topics, he looks at how much change has taken place in the public sector, what determines the speed and breadth of e-government adoption, and what the consequences of digital technology are for the public sector.
Written in a clear and analytical manner, this book outlines the variety of factors that have restricted the ability of policy makers to make effective use of new technology. Although digital government offers the potential for revolutionary change, social, political, and economic forces constrain the scope of transformation and prevent government officials from realizing the full benefits of interactive technology.

Reputation offsets trust judgments based on social biases among Airbnb users
To provide social exchange on a global level, sharing-economy companies leverage interpersonal trust between their members on a scale unimaginable even a few years ago. A challenge to this mission is the presence of social biases among a large heterogeneous and independent population of users, a factor that hinders the growth of these services. We investigate whether and to what extent a sharing-economy platform can design artificially engineered features, such as reputation systems, to override people’s natural tendency to base judgments of trustworthiness on social biases. We focus on the common tendency to trust others who are similar (i.e., homophily) as a source of bias. We test this argument through an online experiment with 8,906 users of Airbnb, a leading hospitality company in the sharing economy. The experiment is based on an interpersonal investment game, in which we vary the characteristics of recipients to study trust through the interplay between homophily and reputation. Our findings show that reputation systems can significantly increase the trust between dissimilar users and that risk aversion has an inverse relationship with trust given high reputation. We also present evidence that our experimental findings are confirmed by analyses of 1 million actual hospitality interactions among users of Airbnb.
