The economics of poverty traps and persistent poverty: An asset-based approach

Longitudinal data on household living standards open the way to a deeper analysis of the nature and extent of poverty. While a number of studies have exploited this type of data to distinguish transitory from more chronic forms of income or expenditure poverty, this paper develops an asset-based approach to poverty analysis that makes it possible to distinguish deep-rooted, persistent structural poverty from poverty that passes naturally with time due to systemic growth processes. Drawing on the economic theory of poverty traps and bifurcated accumulation strategies, this paper briefly discusses some feasible estimation strategies for empirically identifying poverty traps and long-term, persistent structural poverty, as well as relevant extensions of the popular Foster-Greer-Thorbecke class of poverty measures. The paper closes with reflections on how asset-based poverty can be used to underwrite the design of persistent poverty reduction strategies.     

Using ninhydrin to detect gravesoil

Some death scene investigations commence without knowledge of the location of the body and/or decomposition site. In these cases, it is necessary to locate the remains or the site where the body decomposed prior to movement. We hypothesized that the burial of a mammalian cadaver will result in the release of ninhydrin reactive nitrogen (NRN) into associated soil and that this reaction might have potential as a tool for the identification of clandestine graves. Juvenile rat (Rattus rattus) cadavers were buried in three contrasting soil types in Australian tropical savanna ecosystems and allowed to decompose over a period of 28 days. Soils were sequentially harvested and analyzed for NRN. Cadaver burial resulted in an approximate doubling (mean = 1.7 +/- 0.1) in the concentration of soil NRN. This reaction has great potential to be used as a presumptive test for gravesoil and this use might be greatly enhanced following more detailed research.     

Participation rationales,regulatory enforcement,and compliance motivations in a voluntary program context

This article extends the study of regulatory compliance motivations from “traditional” regulatory settings to a government-sponsored voluntary one. We argue that the rationale(s) which motivate participants to engage a voluntary program likely shape which motivations drive them toward (or away from) program compliance. Our study examines the possible influence of program participation rationales alongside that of regulatory agents' enforcement styles and strategies. Leveraging a national survey of certified United States Department of Agriculture organic producers, we find that the more a producer pursues organic certification to increase profits, the more likely they are to report deterrent fears as an important compliance motivation. In contrast, the more a producer becomes certified to support the organic movement, the more heavily they weigh a personal sense of duty to comply. We discuss the implications of these, and other, study findings for compliance motivations theory and voluntary program integrity.     

Admissible and sincere strategies under approval voting

This essay reasses the assumptions of the Brams-Fishburn theory of approval voting, and proposes modifications to make the theory correspond better with likely voting choices. With a small number of candidates, voters who use the inadmissible strategy of voting for all candidates can help to produce a result that better reflects the voters' wishes than is possible with admissible strategies, so we propose a widening of the definition of admissibility to encompass this case. With more than three candidates, we define first-order admissible strategies, which are the most likely strategies to be used in practice, and are also strongly sincere, in that a vote for any candidate is always accompanied by votes for all more or equally-preferred candidates. Their number is less under approval voting than under plurality voting. Both proposed modifications strengthen the technical arguments favoring approval voting over plurality voting.     

The biochemical alteration of soil beneath a decomposing carcass

The processes associated with cadaver decomposition in outdoor settings, particularly those that occur during the extended postmortem interval (>30 days) are poorly understood. Thus, few methods are currently available to accurately estimate the extended postmortem interval (PMI). Of these methods, a soils-based approach has the potential to address the postmortem interval between which entomology and anthropology are the most valuable. Although the validity of soil-based methods has previously been established, little work has been conducted to explain the processes that have been designated for forensic application. As a consequence, we investigated the dynamics of carbon, nitrogen, and phosphorus-based compounds in soil beneath pig (Sus scrofa) cadavers (gravesoil) that were placed on the soil surface over a period of 100 days. Decomposition was assessed through the physical characteristics of the cadaver, soil pH, soil moisture content, and the concentration of total carbon, total nitrogen, soil-extractable phosphorus, and lipid-phosphorus in soil. Cadaver decomposition did not result in a significant difference in soil carbon and moisture content. However, significant (P < 0.05) increases were observed in the concentration of soil pH, total nitrogen, soil-extractable phosphorus, and lipid-phosphorus. Based on the current results, a significant increase in the concentration of gravesoil nutrients represented a maximum PMI of 43 days (lipid-P), 72 days (total nitrogen), or 100 days (soil-extractable phosphorus). This work provides further evidence that a soil-based method has the potential to act as a tool for the estimation of extended PMI.     

Defense Management Challenges for the Next American President

The next American president will face a daunting list of national security problems, including a serious defense budget crunch. The budget crisis will be deepened by the global financial crisis, a tapering of supplemental funding associated with the wars in Iraq and Afghanistan, and the steady growth of military healthcare and other personnel costs. After six years of rapid defense budget increases, the Pentagon has lost the practice of matching strategy and resources. The next president will need to manage risk among investments in irregular warfare, counterterrorism, balancing new super powers, countering weapons of mass destruction, and traditional warfare. He will also need to begin to build non-military “soft power” capabilities outside of the Pentagon.     

"Grab the Signatures and Run": Federal Unity Strategy in Canada from the Referendum to Patriation

Whether as a traumatic event or great accomplishment, the legacy of the First Ministers' Conference of 1981 lives on in Canadian politics. Constitutional negotiations among the prime minister and provincial premiers in 1981 produced the only "packaged" agreement since Confederation to achieve even the minimal support necessary to achieve ratification. The resulting Constitution Act of 1982, which included the Charter of Rights and Freedoms, remains in place and is the principal manifestation of intergovernmental bargaining from over two decades ago. This study reevaluates the strategic interaction and conflict processes that took place between Ottawa and the provinces in negotiations leading up to that fateful November 1981 conference. We apply the sociological framework for assessment of the dynamics of identity contention adopted from McAdam, Tarrow, and Tilly (2001) and find tentative support for its propositions. After an overview of the article's agenda, we present an analytic framework for the study of conflict processes. Second, the background to the constitutional crisis of 1980-81 is summarized. Using the analytic framework, the third section focuses on the federal strategy in the crisis as suggested by minutes from cabinet meetings, and the fourth section examines key events of the First Ministers Conference of November 1981. Fifth, and finally, the contributions of the preceding sections are summed up and ideas are put forward for further research.
