Multiple Routes

From the 1980s through the first decade of the twenty-first century, the spread of democracy across the developing and postcommunist worlds transformed the global political landscape. What drove these changes and what determined whether the emerging democracies would stabilize or revert to authoritarian rule? This book takes a comprehensive look at the transitions to and from democracy in recent decades. Deploying both statistical and qualitative analysis, the book engages with theories of democratic change and advocates approaches that emphasize political and institutional factors. While inequality has been a prominent explanation for democratic transitions, the book argues that its role has been limited, and elites as well as masses can drive regime change. Examining seventy-eight cases of democratic transition and twenty-five cases of reversion to autocracy since 1980, the book shows how differences in authoritarian regimes and organizational capabilities shape popular protest and elite initiatives in transitions to democracy, and how institutional weaknesses cause some democracies to fail. The determinants of democracy lie in the strength of existing institutions and the public's capacity to engage in collective action. There are multiple routes to democracy, but those growing out of mass mobilization may provide more checks on incumbents than those emerging from intra-elite bargains. Moving beyond well-known beliefs regarding regime changes, this book explores the conditions under which transitions to democracy are likely to arise.

AbstractProspero Balbo, the head of a leading Piedmontese noble family, followed a career path similar to that of the versatile French statesman Talleyrand. In the aftermath of 1789, Balbo served under four different regimes: the Old Regime monarchy, the Russian provisional administration of Piedmont in 1799, the Napoleonic empire, and the restored Savoy monarchy. After the short-lived revolutionary movement of 1821 in Sardinia-Piedmont, Prospero lost his job as interior minister and his son, Cesare, was forced into exile. The revolutionary waves of 1820–1821 were the most recent of numerous disruptive events and regime changes that jeopardized Europe and the Atlantic world between the late 1770 s and the early 1820 s. These five decades of revolutionary upheavals, wars, and persistent insecurity forced the traditional elites to mobilize their material, cultural, and social resources to preserve their prestige and power. Based on extensive archival research, this article examines the resilience-strengthening resources and strategies implemented by members of the Balbo family during periods of political turmoil. In doing so, the article aims to develop an analytical and conceptual framework to describe historical processes in terms of resilience and vulnerability. This new approach enables us to look afresh at elite transformations and at the dynamics of political change and continuity in early nineteenth-century Europe.

AbstractThe availability of dissolved inorganic and organic nutrients and their transformations along the fresh to marine continuum are being modified by various natural and anthropogenic activities and climate-related changes. Subtropical central and eastern Florida Bay, located at the southern end of the Florida peninsula, is classically considered to have inorganic nutrient conditions that are in higher-than-Redfield ratio proportions, and high levels of organic and chemically-reduced forms of nitrogen. However, salinity, pH and nutrients, both organic and inorganic, change with changes in freshwater flows to the bay. Here, using a time series of water quality and physico-chemical conditions from 2009 to 2019, the impacts of distinct changes in managed flow, drought, El Niño-related increases in precipitation, and intensive storms and hurricanes are explored with respect to changes in water quality and resulting ecosystem effects, with a focus on understanding why picocyanobacterial blooms formed when they did. Drought produced hyper-salinity conditions that were associated with a seagrass die-off. Years later, increases in precipitation resulting from intensive storms and a hurricane were associated with high loads of organic nutrients, and declines in pH, likely due to high organic acid input and decaying organic matter, collectively leading to physiologically favorable conditions for growth of the picocyanobacterium, Synechococcus spp. These conditions, including very high concentrations of NH4+, were likely inhibiting for seagrass recovery and for growth of competing phytoplankton or their grazers. Given projected future climate conditions, and anticipated cycles of drought and intensive storms, the likelihood of future seagrass die-offs and picocyanobacterial blooms is high.

Ideological Dimension

The popular movements in 2011 led to many regime changes that resulted in amended or new constitutions in the Middle East and North Africa region. The constitutional debates concentrated mainly on the functions of the constitutions in authoritarian regimes, constitution-making processes, and the role of Islam during and after the uprisings. However, no research has analyzed the ideological dimensionality of the Middle Eastern and North African constitutions. By analyzing 19 newly enacted, drafted, and amended constitutions before and after the popular movements in the region, this article shows that the single ideological dimension in the constitutions can be defined by the openness of a state for liberal and modern values. This ideological dimension encompasses all the regional political debates on the political regime dynamics, the inclusion of rights and liberties, and the role of Islam. Besides offering an alternative typology for the constitutions in the region, this article also provides evidence for the beginning of the fourth phase of Islamic constitutionalism that merges the ideas of rule of law, which originates from democratic notions, and Islamic norms.

The study of changes in river discharge is important for regional climate variability characterization and for development of an efficient water resource management system. The hydrological regime of rivers and their long-term changes in Latvia were investigated. Four major types of river hydrological regimes, which depend on climatic and physicogeographic factors, were characterized. These factors are linked to the changes observed in river discharge. Periodic oscillations of discharge, and low- and high-water flow years are common for the major rivers in Latvia. A main frequency of river discharge regime changes of about 20 and 13 years was estimated for the studied rivers. A significant impact of climate variability on the river discharge regime has been found.
