Understanding human aggression: New insights from neuroscience

The present paper reviews and summarizes the basic findings concerning the nature of the neurobiological and behavioral characteristics of aggression and rage. For heuristic purposes, the types of aggression will be reduced to two categories — defensive rage (affective defense) and predatory attack. This approach helps explain both the behavioral properties of aggression as well as the underlying neural substrates and mechanisms of aggression both in animals and humans. Defensive rage behavior is activated by a threatening stimulus that is real or perceived and is associated with marked sympathetic output. This yields impulsivity with minimal cortical involvement. Predatory attack behavior in both animals and humans is generally planned, taking minutes, hours, days, weeks, months, or even years (with respect to humans) for it to occur and is directed upon a specific individual target; it reflects few outward sympathetic signs and is believed to require cortical involvement for its expression. Predatory attack requires activation of the lateral hypothalamus, while defensive rage requires activation of the medial hypothalamus and midbrain periaqueductal gray (PAG). Both forms of aggressive behavior are controlled by components of the limbic system, a region of the forebrain that is influenced by sensory inputs from the cerebral cortex and monoaminergic inputs from the brainstem reticular formation. Control of aggressive tendencies is partly modifiable through conditioning and related learning principles generated through the cerebral cortex.     

地方治理与民主现代化

民主现代化就意味着限制和分散政府权力以及加强地方政府建设。要想建立有效的地方政府体制,就必须重视提高公民参与,建设公-私伙伴关系,加强管理能力,储备充裕的财政资源等核心问题。     

Representing the periphery: Highland commissioners in the seventeenth-century Scottish Parliament,c.1612–1702

While a significant amount of work has recently been conducted on the procedure and practices of the pre-1707 Scottish Parliament, remarkably little is known about the nature of local representation within the chamber. This article seeks partially to address that gap through detailed analysis of the elected representation of one region – the Scottish Highlands – within the seventeenth-century Parliament. Considering attendance rates, the identity of Highland representatives (‘commissioners’), the means of their election and their activities once elected, the article argues that Highland engagement with Parliament was much more significant than is often assumed. This, in turn, suggests that further constituency-level studies are needed in order to provide a fuller picture of Parliament's relationship with the country at large.     

The Environmental Justice Movement: Equitable Allocation of the Costs and Benefits of Environmental Management Outcomes

We present a review of theoretical and methodological advances in the social scientific literature on environmental inequality/racism and argue for new directions in research efforts that pay more attention to (1) the historical forces driving environmental justice conflicts; (2) the complex role of stakeholders in these struggles; (3) the role of social inequality, particularly the trade-offs between environmental protection and social equity; and (4) the impact of social movement activity on the state of environmental protection. Drawing on a case study of an environmental justice conflict in the United States, we find that environmental inequality impacts many actors with often contradictory and cross-cutting allegiances. These struggles therefore become a moving drama—a process—rather than a cross-sectional outcome. We conclude with an analysis of environmental inequality on a global scale and argue that the role of transnational capital remains largely untheorized in the literature. We suggest new models for explaining environmental inequality's causes and consequences.     

Moving Policy Theory Forward: Connecting Multiple Stream and Advocacy Coalition Frameworks to Policy Cycle Models of Analysis

The stages/policy cycle, multiple streams, and Advocacy Coalition Framework (ACF) approaches to understanding policy processes, all have analytical value although also attracting substantive criticism. An obvious direction for research is to determine whether the multiple streams framework and the ACF can be refined and applied to other dimensions of policy‐making set out in the policy cycle model. This article argues that extending and modifying Kingdon's framework beyond the agenda‐setting stage is best suited to this endeavour. Doing so makes it possible to bring these three approaches into alignment and enhances our understanding, although retaining the core insights of each.     

Thinking about the ‘Local’ of Local Government: a Brief History of Invention and Reinvention

In 2004, Local Government Studies published an article in which I reflected on the implications of new Labour’s modernisation agenda for the remaking of local government and the reshaping of the welfare state. Here I return to some of the issues raised in that paper in the different context of localism, austerity and dreams of urban entrepreneurialism. I argue that exploring the changing meanings of the local, as a contested political as well as geographical category, is a fundamental task for those of us seeking to understand the nature of contemporary local government; the wider processes of state restructuring which frame it; and the possibilities of local politics.     

Birth and Death(?) of the Anti-Fracking Movement: Inferences from Quantity of Coverage Theory

Public opposition to fracking is one of numerous movements expressing concern about health or environmental risks of a (usually) new technology. These have at their core an esoteric dispute between technical experts, but laypeople also become actively involved, usually as volunteers. They may live close to pertinent sites, motivated by fears for their families and property, or they may be people living farther away, attracted to the opposition for ideological reasons. (Opposition to fracking is a politically liberal position.) Activism is increasingly motivated when the issue is “hot” and diminishes when it cools down. According to Quantity of Coverage Theory (QCT), the “hotness” of an issue – therefore the degree of activism -- largely depends on its presence in the mass media. The American anti-fracking movement arose fairly quickly around 2010–11. News coverage peaked during 2012–14 and is now diminishing. Similar peaks and declines are observed in British and German news media, consistent with the power of central American media to influence news coverage in other industrial nations. Inferentially, from declining news coverage, the anti-fracking movement is waning, perhaps dying. Lacking direct measures of activism, QCT provides a lens through which to see the rise and fall of the movement.     

Health Risks for Poultry Workers in Brazil in the COVID-19 Pandemic

This article discusses labour relations in the poultry industry in Brazil in the context of the COVID-19 pandemic. In the meat production and processing industries there have been many complaints about abusive practices that put workers' health at risk. In several small cities across the country, slaughterhouses already act as pandemic contagion risk hotspots. We present an overview of the demeaning treatment of workers and the risks to public health associated with Brazil's poultry industry.
