Simulating transfer and persistence of a chemical marker powder for Lycopodium clavatum spores

In this research a chemical marker powder, based on Lycopodium clavatum spores, was studied to determine its transfer and persistence on a T-shirt. Such chemical marker powders are used to provide evidence that a person has handled a covertly marked object, such as a drug package. The powder was found to transfer readily between a marked item and the person handling it. The powder was found to persist on a T-shirt for up to 13 h; however, there was only a very small amount of powder remaining at this time. The rate of loss of the L. clavatum spores was found to follow a decay curve. The largest decrease in spores from the T-shirt was seen in the first 2 h after the marked item had been handled.

Colby college conference report

In March 1995 the Japanese doomsday cult Aum Shinrikyo conducted a well-timed and coordinated nerve gas attack on the Tokyo subway system. This represented the first use of such a weapon by a nonstate group and sent shock waves around the world. The shock came not least because the attack had been completely unexpected despite years of theorizing and literature discussing just such a possibility. The purpose of this article is to address the broad issue of terrorist use of weapons of mass destruction as it applies to Aum Shinrikyo, and within this context to critically analyze the three books listed above. Each offers a different look at Aum in terms of the group itself and of what lessons might be drawn from this new and frightening development in "terrorist" violence.     

Management,markets and democracy: Australian local government reform in the 1990s

Australian local government has been subjected to extensive reform during the 1990s. This article considers the three main dimensions of the reforms — changes to management structures, the introduction of competition policy, and municipal consolidation. It reviews the evidence available about the nature of outcomes and examines the impact of the reforms on governance values. It is argued that, so far, economic considerations have been balanced by a commitment to community particpation. Recent political developments, however, may yet prove to be an emerging threat.     

Beyond the property debate: animal welfare as a public good

Abstract

Animal protection is socially constructed through laws specifying which animals should be protected and how. Most jurisdictions codify animal abuse by specifying the legal protections granted to animals. While these vary between jurisdictions, western legal systems generally provide for better levels of animal protection by incorporating animal welfare and wildlife crime laws into criminal justice systems. UK legislation has long held that animal welfare is a public good, thus animals should be protected in the public interest. However, despite the protective provisions of animal protection laws they generally fall short of giving animals actual rights, protection exists only to the extent that animal and human interests coincide. Animals’ legal status as property dictates that much anti-animal abuse and wildlife crime legislation is about allowing animal exploitation commensurate with human interests. However, UK legislation in the form of the Animal Welfare Act 2006 subtly shifts this position in respect of domestic animals by imposing a duty of care towards companion animals. This paper argues that by requiring owners and responsible persons to give active consideration to the needs of individual companion animals, the Animal Welfare Act provides animals with a level of protection that amounts to a form of legal rights.     

Amazonian peasant livelihood differentiation as mutuality-market dialectics

ABSTRACT

Economistic approaches to the study of peasant livelihoods have considerable academic and policy influence, yet, we argue, perpetuate a partial misunderstanding – often reducing peasant livelihood to the management of capital assets by rational actors. In this paper, we propose to revitalize the original heterodox spirit of the sustainable livelihoods framework by drawing on Stephen Gudeman’s work on the dialectic between use values and mutuality on the one hand, and exchange values and the market on the other. We use this approach to examine how historically divergent mutuality-market dialectics in different Amazonian regions have shaped greater prominence of either extractivism or agriculture in current livelihoods. We conclude that an approach centered on the mutuality-market dialectic is of considerable utility in revealing the role of economic histories in shaping differential peasant livelihoods in tropical forests. More generally, it has considerable potential to contribute to a much-needed re-pluralization of approaches to livelihood in academia and policy.     

Revisiting the Instrumentality of Voice: Having Voice in the Process Makes People Think They Will Get What They Want

Research on procedural justice has found that processes that allow people voice (i.e., input) are perceived as fairer, and thus elicit more positive reactions, than processes that do not allow people voice. Original theorizing attributed these effects to beliefs that the provision of voice enhances people’s sense of process control, which people were assumed to value because it impacts their perceived likelihood of receiving desired outcomes (the instrumental perspective of procedural justice). Subsequent research questioned this perspective, arguing that outcome expectations do not account for the effects of voice. However, this subsequent research failed to directly examine the interplay of voice, outcome expectations, and reactions. The current studies revisit and extend research on this topic by asking whether manipulations of voice act as shared circumstance effects. Confirming an untested implication of the instrumental perspective, we show that giving everyone voice increases their belief, ex-ante, that they are likely to win an upcoming competition. However, this instrumental belief accounts for only part of the effects of voice on perceived procedural fairness and on general reactions to outcomes. Results suggest that voice does indeed have instrumental significance, an implication not adequately recognized in current justice theorizing. However, this instrumentality does not, by itself, explain why people value having a voice in processes that affect them.
