Law versus Morality as Regulators of Conduct

It is evident that both law and morality serve to channel ourbehavior. Law accomplishes this primarily through the threatof sanctions if we disobey legal rules. Morality too involvesincentives: bad acts may result in guilt and disapprobation,and good acts may result in virtuous feelings and praise. Thesetwo very different avenues of effect on our actions are examinedin this article from an instrumental perspective. The analysisfocuses on various social costs associated with law and morality,and on their effectiveness, as determined by the magnitude andlikelihood of sanctions and by certain informational factors.After the relative character of law and of morality as meansof control of conduct is assessed, consideration is given totheir theoretically optimal domains—to where moralityalone would appear to be best to control behavior, to wheremorality and the law would likely be advantageous to employjointly, and to where solely the law would seem desirable toutilize. The observed pattern of use of morality and of lawis discussed, and it is tentatively suggested that the observedand the optimal patterns are in rough alignment with one another.     

Farmer-to-farmer extension: opportunities for enhancing performance of volunteer farmer trainers in Kenya

Farmer-to-farmer extension (FFE) is playing a complementary role to formal extension services in facilitating the spread of agricultural technologies and improving farmers’ capacities. The effectiveness and sustainability of such programmes depend on volunteer farmer trainers (VFTs) having technical skills and overcoming process-related challenges that hinder them from achieving the desired outcomes. This article uses quantitative and qualitative data collected from seven sites to explore the challenges experienced by VFTs as they share their knowledge on livestock feed innovations in a dairy development project in Kenya. Sustainable opportunities for enhancing VFTs’ performance are discussed.     

Sex Determination by Discriminant Function Analysis of Lumbar Vertebrae

Sex determination is critical for developing the biological profile of unidentified skeletal remains. When more commonly used elements (os coxa, cranium) for sexing are not available, methods utilizing other skeletal elements are needed. This study aims to assess the degree of sexual dimorphism of the lumbar vertebrae and develop discriminant functions for sex determination from them, using a sample of South African blacks from the Raymond A. Dart Collection (47 males, 51 females). Eleven variables at each lumbar level were subjected to univariate and multivariate discriminant function analyses. Univariate equations produced classification rates ranging from 57.7% to 83.5%, with the highest accuracies associated with dimensions of the vertebral body. Multivariate stepwise analysis generated classification rates ranging from 75.9% to 88.7%. These results are comparable to other methods for sexing the skeleton and indicate that measures of the lumbar vertebrae can be used as an effective tool for sex determination.     

Strategic Challenger Entry in a Federal System: The Role of Economic and Political Conditions in State Legislative Competition

Over a third of state legislators do not face challengers when seeking reelection. Existing analyses of state legislative contestation almost exclusively focus on the stable institutional features surrounding elections and ignore conditions that change between elections. I remedy this oversight by investigating how political contexts influence challenger entry. State legislators—particularly members of the governor's party—more often face opposition during weak state economies, but the president's copartisans are even more likely to receive a challenger when the president is unpopular. My findings suggest that both national‐ and state‐level political conditions have an important impact on challengers' entry strategies.     

Prison Conditions, Capital Punishment, and Deterrence

Previous research has attempted to identify a deterrent effectof capital punishment. We argue that the quality of life inprison is likely to have a greater impact on criminal behaviorthan the death penalty. Using state-level panel data coveringthe period 1950–90, we demonstrate that the death rateamong prisoners (the best available proxy for prison conditions)is negatively correlated with crime rates, consistent with deterrence.This finding is shown to be quite robust. In contrast, thereis little systematic evidence that the execution rate influencescrime rates in this time period.     

The Taiwan Strait: A Continuing Status Quo of Deadlock?

Relations across the Taiwan Strait have demonstrated over the past 50 years a cyclical nature, revolving between states of limited tension or conflict and generally peaceful and politically acceptable stalemate. Individual policy directions followed by all of the three main actors in cross-Strait relations--China, Taiwan and the United States--continue to be pursued with a high degree of ambivalence, as countervailing political imperatives mean that any policy contains within itself the seeds for its own reversal. Any equilibrium is consequently inherently unstable, yet also drives relations back to a status quo of deadlock from which a new cycle can again commence. Given the full range of objectives on all sides, there is little likelihood of the presently existing deadlocked status quo moving towards a stable resolution. The state of neither war nor peace will continue in the Taiwan Strait, but the margin for error in probable future cycles of tension and stability remains very small.     

The Greater Yellowstone policy debate: What is the policy problem?

Yellowstone National Park and the surrounding mountainous region comprise the Greater Yellowstone Ecosystem (GYE), a 19 million acre area that is one of the few relatively intact ecosystems in the lower 48 states. Conservationists believe that continuation of present land management practices in the region will disrupt the ecological integrity of the GYE. Many authors have identified and described these threats, but as yet there has been no sustained effort to make sense of these threats in the context of the ongoing dynamic policy debate. We develop the foundation for such understanding by examining the implicit problem definitions that have emerged from this debate. They fall into three general categories: 1) a scientific definition, 2) an economic definition, and 3) a bureaucratic definition. This process produces an exploratory definition of the policy problem, which suggests a strategy for better understanding and policy design. We propose several intervention points at which substantive, one-the-ground improvements in the management of the GYE are possible.
