This forum builds on the discussion stimulated during an online salon in which the authors participated on June 25, 2020, entitled “Archaeology in the Time of Black Lives Matter,” and which was cosponsored by the Society of Black Archaeologists (SBA), the North American Theoretical Archaeology Group (TAG), and the Columbia Center for Archaeology. The online salon reflected on the social unrest that gripped the United States in the spring of 2020, gauged the history and conditions leading up to it, and considered its rippling throughout the disciplines of archaeology and heritage preservation. Within the forum, the authors go beyond reporting the generative conversation that took place in June by presenting a road map for an antiracist archaeology in which antiblackness is dismantled.

Asymmetrical Power

AbstractNegotiators for powerful, self-reliant states tend to be less responsive to weak states relative to domestic constituents, while negotiators for states entangled in ties of asymmetric interdependence with more powerful states tend to be more responsive to the demands of powerful states than to the demands of domestic constituents. Asymmetrical power does not necessarily lead to asymmetrical results, however, because negotiators in weaker states may, nevertheless, have more attractive non-agreement alternatives and a longer shadow of the future. Negotiators with attractive non-agreement alternatives will be more willing to put agreement at risk by withholding concessions in the negotiation process. Centralized and vertical institutions are often a bargaining liability precisely because weak states tend to be less responsive to domestic constituents, whereas divided government can be a major asset. These propositions are demonstrated through an analysis and reconstruction of the North American Free Trade negotiation process.

The Future

Abstract The Prairie Pothole Region (PPR) of the northern Great Plains is a vital ecosystem responsible each year for producing 50%–80% of new recruits to the North American duck population. Climate variability and change can impact the hydrology and ecology of the region with implications for waterfowl populations. The historical relationship between PPR wetlands, duck populations, and seasonal hydroclimate are explored. Model experiments from phase 5 of the Coupled Model Intercomparison Project are used to determine whether a recent wetting trend is due to natural variability or changing climate and how PPR hydroclimate will change into the future. Year-to-year variations in May duck populations, pond numbers, and the Palmer drought severity index are well correlated over past decades. Pond and duck numbers tend to increase in spring following La Niña events, but the correlation is not strong. Model simulations suggest that the strengthening of the precipitation gradient across the PPR over the past century is predominantly due to natural variability and therefore could reverse. Model projections of future climate indicate precipitation will increase across the PPR in all seasons except summer, but this gain for surface moisture is largely offset by increased evapotranspiration because of higher temperatures and increased atmospheric evaporative demand. In summer, the combined effects of warming and precipitation changes indicate seasonal surface drying in the future. The presented hydroclimate analyses produce potential inputs to ecological and hydrological simulations of PPR wetlands to inform risk analysis of how this North American waterfowl habitat will evolve in the future, providing guidance to land managers facing conservation decisions.

The Future

Intergenerational relationships between grandparents and grandchildren can offer tremendous benefits to family members of each generation. The demography of grandparenthood – the timing, length and population characteristics – shape the extent to which young children have grandparents available, how many grandparents are alive, and the duration of overlap with grandparents. In this chapter, we examine how the demography of grandparenthood varies across 16 countries in Europe and two countries in North America, and why it is changing. Next, we examine variation in two key determinants of intergenerational relationships – the labour force participation and health of grandparents. Last, we comment on some important changes in the demography of grandparenthood that may come in the future.

Guiding Principles

The legalization of sports gambling has recently become a major social policy issue in some North American jurisdictions. Unfortunately, there are few guiding principles to help policymakers in their deliberations. This paper presents a synopsis of the main practical and moral arguments for and against sports gambling. The discussion of the consequences of legalizing sports gambling follows a sociological overview that emphasizes the scope, growth, and appeal of the activity. The concluding section examines the future of sports gambling: why legalization appears inevitable, the formats legalized sports gambling may take, and where in North America the enabling legislation is most likely to surface.
