This paper examines Funan County’s ‘Three-Fix’ policy as a significant case of China’s agricultural procurement reforms. Utilising extensive archival materials and data, it focuses on the interactions between central and local governments in shaping rural governance and agricultural policy. The study evaluates the policy’s effectiveness in stabilising grain procurement and fostering cooperative relationships between the state and farmers, while also identifying its limitations, such as uneven implementation, local resistance, and inconsistent enforcement. By analysing the policy’s impact on farmers’ production behaviours, social psychology, and local governance, the research uncovers the intricate political economy underlying early reforms in the People’s Republic of China. The findings highlight the necessity of balancing central and local flexibility in policy design and implementation and offer valuable lessons for contemporary rural governance and development.
We study the transport and deposition of inhaled aerosols in a mid-generation, mucus-lined lung airway, with the aim of understanding if and how airborne particles can avoid the mucus and deposit on the airway wall – an outcome that is harmful in case of allergens and pathogens, but beneficial in case of aerosolised drugs. We adopt the weighted-residual integral boundary-layer model of Dietze and Ruyer-Quil (J. Fluid Mech. 762, 2015, 68–109, to describe the dynamics of the mucus–air interface, as well as the flow in both phases. The transport of mucus induced by wall-attached cilia is also considered, via a coarse-grained boundary condition at the base of the mucus. We show that the capillary-driven Rayleigh–Plateau instability plays an important role in particle deposition by drawing the mucus into large annular humps and leaving substantial areas of the wall exposed to particles. We find, counter-intuitively, that these mucus-depleted zones enlarge on increasing the mucus volume fraction. Our simulations are eased by the fact that the effects of cilia and air turn out to be rather simple: the long-term interface profile is slowly translated by cilia and is unaffected by the laminar airflow. The streamlines of the airflow, though, are strongly modified by the non-uniform mucus film, and this has important implications for aerosol entrapment. Particles spanning a range of sizes (0.1–50 microns) are modelled using the Maxey–Riley equation, augmented with Brownian forces. We find a non-monotonic dependence of deposition on size. Small particles diffuse across streamlines due to Brownian motion, while large particles are thrown off streamlines by inertial forces – particularly when air flows past mucus humps. Intermediate-sized particles are tracer-like and deposit the least. Remarkably, increasing the mucus volume need not increase entrapment: the effect depends on particle size, because more mucus produces not only deeper humps that intercept inertial particles, but also larger depleted zones that enable diffusive particles to deposit on the wall.
This chapter examines the national-scale origins and political linkages of land mafias and rural militias in Brazil. These linkages, especially to political power, explain how, over just a few decades, an RDPE of active and open land-grabbing mafias has spread from southern Brazil to the Amazon. These cases illustrate the dynamics by which federal-level changes can expand an RDPE system to the national scale and to other parts of the same jurisdiction, polity, and political system. The land-grabbing process is linked to illegalities and violence, which are mutually self-reinforcing through the logics operating in these systems. This chapter examines the rapid post-2019 transformation of pastures into monoculture soybean or corn plantations, especially in southeastern Acre and along the paved BR-163 highway. Part of the problem is the institutionalization of illegal land grabbing and its mafia-like tactics, whose continuation is ensured through legal loopholes and ambiguities. The situation worsened, especially during the reign of Jair Bolsonaro (2019–2023), as land mafia dynamics penetrated deeper into the sociopolitical fabric of Brazil.
We inquire how a commodity cartel is created by studying the negotiations between Colombia and Brazil to stabilize the international coffee market in the 1930s. We show how differences among actors involved in the industry within the negotiating countries in terms of land ownership and type of coffee produced, prevented early cartelization agreements. Cartelization was only achieved when four factors converged: financial and infrastructural capability to store excess production, in-depth knowledge of the industry by the negotiating parties, full government support, and presence of a third-party enforcer. We combine an innovative game-theoretic approach with previously unexplored archival sources.
In the early nineteenth century, parliamentarians in Britain debated whether the Crown’s prerogative could be used to exclude and deport aliens. These arguments were later expanded in litigation about the immigration practices of the British colonies. On behalf of the colonies, some lawyers proposed that the executive powers of colonial officials were informed by the writings of Samuel Pufendorf and Emer de Vattel, who had claimed that the state could forbid the entry of foreigners. But across three disputes, from Mauritius (1830s), Australia (1880s), and Canada (1900s), lawyers in the colonies and in London revealed several doubts about this line of thought. In doing so, they expressed a more general skepticism about the relevance of sovereignty to immigration control.
This chapter explores the ongoing and novel merging of gold mining with organized crime, highlighting the relation of drug trafficking, land grabbing, and other related sectors to deforestation. The recent gold-mining expansion and boom in the Amazon is linked to gold markets and the global political economy. The chapter scrutinizes the rise of narco-gold mining, linking drug trade, organized criminal groups, and money laundering with rainforest gold and the surge of authoritarian and mafia-like power. During the Bolsonaro era there was a significant deepening of the link between gold-mining activities and organized drug traffickers and criminal networks. In southwestern Pará, gold mining is the leading cause of deforestation inside areas like the upper Tapajós Munduruku Indigenous lands near Jacareacanga. This chapter utilizes field research experiences, interviews, and ethnographic observations to illustrate the complex dilemmas faced by communities currently being pressured and divided by increasing gold extraction in their territories. In the end of the chapter the discussion turns to solutions for how to address these and other root causes of deforestation in political economy.
As gold prices have soared, the Amazon and its inhabitants have had to bear the brunt of a rampant, environmentally destructive gold-mining rush. Small and medium-sized illegal, informal, and other irregular forms of so-called artisanal gold mining, as well as large-scale corporate gold mines, cause major and multifaceted socioenvironmental–health–human rights crises. The dynamics of the gold-mining boom are important to understand the key political economic sectors behind forest degradation and deforestation and to highlight how RDPEs work. The overall situation in the Amazon is presented, analyzing the causes of gold mining and the violence, especially in Peru, Brazil, and other key regions. The triple frontier between Colombia, Venezuela, and Brazil is also analyzed as the irregular gold-mining RDPE is one of the most important drivers of deforestation. In this region, gold-mining operations are led by ex-guerilla groups in Venezuela, paramilitaries and other armed groups in Colombia, and, increasingly, by the First Capital Command and other drug factions from southeastern Brazil in Roraima’s Yanomami Indigenous lands.
In June 2021, the last of the eighteen tomes of Tocqueville’s Oeuvres complètes was published by Gallimard. This project had been instigated more than seventy years earlier by Jacob Peter Mayer, a German Jewish writer who had fled to England in 1936. Mayer believed that Tocqueville’s insights into democracy, fanaticism, and revolution were more relevant to the nation-states of the postwar era than those of any other writer, and so he embarked upon a mission to publish Tocqueville’s complete works to underscore their contemporary relevance. Utilizing many unpublished documents, this article tells the story of how Mayer came to direct the publishing venture, how he battled with the national commission that was set up by the French government to oversee it, and how he eventually lost control of the project after thirty years as editor in chief. His experience confirmed in his eyes that free states lacked democratic cultures sufficient to sustain them.
The matrixdist R package provides a comprehensive suite of tools for the statistical analysis of matrix distributions, including phase-type, inhomogeneous phase-type, discrete phase-type, and related multivariate distributions. This paper introduces the package and its key features, including the estimation of these distributions and their extensions through expectation-maximization algorithms, as well as the implementation of regression through the proportional intensities and mixture-of-experts models. Additionally, the paper provides an overview of the theoretical background, discusses the algorithms and methods implemented in the package, and offers practical examples to illustrate the application of matrixdist in real-world actuarial problems. The matrixdist R package aims to provide researchers and practitioners a wide set of tools for analyzing and modeling complex data using matrix distributions.
The question to what extent EU law is constitutive of European society as articulated in Article 2 TEU is, at its core, a question about the nature, scope and limits of EU law. This article suggests certain clear limits to EU law’s ability to make the European society visible in law, or legible for law – let alone composable through law. The article is entitled ‘Is this Europe?’ as a direct challenge to the widely held belief that EU law is somehow constitute of European integration; that EU law contains all that European integration is, can and will be. Sure, the Europe that we see when analysing cases, treaties and legislation matters. But the ‘real’ Europe – the one that is felt, experienced, lived – resides in what happens due to, in spite, or irrespective of those cases, treaties and legislation. For EU law to remain sensitive to its society, then, EU law needs to reformulate the expectations it has of itself and create an analytical framework that allows it to transcend its immanent nature. This requires three changes to the way we ‘do’ EU law. First, more sensitivity to the material and relational context in which EU law operates. Second, creating space for forms of lay knowledge that are rooted in social praxis. Third, more ambition and playfulness in the way we – as scholars – ‘speak’ EU law.
We prove that there is an absolute constant $C{\,\gt\,}0$ such that every k-vertex connected rainbow graph R with minimum degree at least $C\log k$ has inducibility $k!/(k^k-k)$. The same result holds if $k\ge 11$, and R is a clique. This answers a question posed by Huang, that is a generalisation of an old problem of Erdös and Sós. It remains open to determine the minimum k for which this is true.
A new theoretical framework is required to expose how the underlying political economic systems function and drive deforestation. The hypotheses and case studies are presented while situating deforesting processes in the international system and its many subsystems, which are composed of partially interlinked sectors that often compete for the same land areas. This is a detailed political economic analysis, based on regionally situated world-ecological analyses, which consider the power that different sectors have in causing the loss of forests, such as Brazilian ranching speculation, Amazonian gold mining, and Finnish pulp and energywood forestry. The chapter contends that there is a need to cultivate a deeper, comparative, and global crises-situated understanding of the role these forces have in driving deforesting. One must also understand the local-level enabling factors and the role of resistance. Insights are woven together from several disciplines and approaches such as political ecology and world-ecology into a new conceptual framework that can be widely applied to explain global development dynamics, beyond the specific application to deforestation.
This paper presents the palaeoecological analysis of five latest Pleistocene (17,500–13,500 cal yr BP) Arctic ground squirrel (Urocitellus parryii) middens from three sites in the Klondike goldfields of central Yukon Territory. Plant and invertebrate macrofossil records were represented by 24 and 20 taxa, respectively, providing a record of the local environment and the earliest known occurrences in Yukon Territory for several taxa (e.g., the robber fly [Lasiopogon sp.] and marsh yellowcress [Rorippa cf. palustris]). The plant and invertebrate assemblages indicate the persistence of steppe-tundra to at least 13,680 cal yr BP by the preservation of taxa typically occupying dry sites, many of which remain components of grasslands and south-facing azonal steppe communities in present-day Yukon Territory. In the context of shrub expansion that is documented to have occurred by 14,000 cal yr BP in interior Alaska, we consider the taphonomic biases associated with Arctic ground squirrel middens that may lead to the lack of shrub macrofossils preserved at the sites. Our study provides an ecologically unique and chronologically constrained perspective on the local persistence of steppe-tundra in easternmost Beringia despite the regional expansion of shrubs.
Research indicates a lack of presence of lower socioeconomic status (SES) individuals in parliament, hindering their representation due to a lack of shared experiences between low SES citizens and representatives. Theorists argue that understanding low SES experiences depends not only on representatives’ own SES but also on those closest to them. However, little is known about whether elected representatives count lower SES citizens in their intimate network. Surveying 1,185 representatives across 13 Western countries, we examine the educational attainment and social class of their parents, partner, and two closest friends. In none of these countries do representatives’ ties mirror the share of lower SES citizens in the population. The results are only slightly better when we examine how many representatives have at least a single lower SES tie. We also find evidence for homophily. High SES representatives tend to associate with high SES individuals, and they tend to do that much more than high SES citizens associate with other high SES citizens. This shows that representatives who could benefit most from lower SES perspectives in their personal networks often lack them.
