How High-Yield Farming Saves Nature

High-yield farming—more agricultural output per acre of farmland—has been a boon to mankind and to nature. If today’s agricultural efficiency was the same as in the 1950s, the world would need three times the cropland to produce today’s food supply. That would mean that 15-16 million mi² of forest would have been destroyed—all the global forest area available today. Rising population and increased affluence will require a tripling of agricultural efficiency in the next 50 years if we are to protect wildlife at the same time. More investment in agricultural research and education will be required, but this is what produced the previous green revolution.

Brothers’ Keepers?

Relying on rarely analyzed public opinion data from the 1930s and early 1940s, we take issue with the notion popular in contemporary liberal circles that the New Deal era represented a period of expansive commitment to the security and well-being of the poor and politically disenfranchised. At least where the public is concerned—as opposed to the progressive policy makers in the Roosevelt administration—the jobless were regarded with suspicion, immigrants should be forced to “go home,” women belong in the kitchen not on the shop floor. The harsher the economic conditions (by state), the more conservative were the public attitudes. Hence New Deal legislative victories accrued despite rather than because of public support.

Iraq the Vote: Retrospective and Prospective Foreign Policy Judgments on Candidate Choice and Casualty Tolerance

In this article, we model the effect of foreign policy attitudes on both vote choice and casualty tolerance, using survey data collected during the 2004 election. We show that prospective judgments of the likelihood of success in Iraq and retrospective judgments of whether the war in Iraq was right are significant determinants of both vote choice and casualty tolerance. The prospective judgment of success is key in predicting casualty tolerance, while retrospective judgment of whether the war was right takes precedence in determining vote choice. In addition, there is an important interaction between the two variables, so the effect of one is conditional on the value of the other. We believe this is compelling evidence that foreign policy matters, and that it matters in reasonable ways.

A Question of Authority: Religion and Cultural Conflict in the 2004 Election

In this study I adopt a view of cultural conflict that extends beyond the usual set of controversial “moral” issues like abortion and gay rights to include symbolic issues related to patriotism and group affect. Using a set of survey items asking about respondents’ preferences in child-rearing, I create a measure of individuals’ orientations toward authority that proves to be a potent predictor of attitudes on cultural issues, affect toward social groups, party identification, and vote choice. This authority effect persists even in the presence of extensive multivariate controls for demographic and religious variables. I find that both authority measures and religion measures shape political attitudes, suggesting the need for a multi-faceted approach to understanding cultural conflict.

Implicit Attitudes,Explicit Choices: When Subliminal Priming Predicts Candidate Preference

Citizens are asked to make many judgments in politics, often in the face of scarce information and limited motivation. In making political judgments, citizens may rely upon a variety of cues, including the partisanship, ethnicity, race, or sex of candidates. Some cues, however, are more democratically troublesome than others. Democratic norms of equality suggest that attitudes towards racial or ethnic groups should not influence citizens’ evaluations of candidates. Often, however, attitudes towards these groups do matter. This article identifies a limiting condition on the effect of group attitudes: the presence of a party cue. I demonstrate that attitudes towards Hispanics influence willingness to support a Hispanic candidate, but only in the absence of a party cue. The article also contributes to existing work by analyzing both explicit and implicit measures of attitudes towards groups. Explicit measures include stereotypes and feeling thermometers; implicit measures are derived from a subliminal priming task. Subjects with positive attitudes towards Hispanics (whether these attitudes were measured implicitly or explicitly) were more likely to support the Hispanic candidate, in the absence of party cues. Subjects with negative attitudes towards Hispanics were less likely to support the Hispanic candidate, in the absence of party cues. The presence of party cues, however, eliminates the impact of attitudes towards Hispanics on political choice.

In Principle <Emphasis Type="Italic">and</Emphasis> in Practice: Learning Political Tolerance in Eastern and Western Europe

Political tolerance is a key democratic value believed to undergird successful and healthy democracies. In nascent democracies especially, citizens must tolerate the views and participation of opposing groups in order to ensure methodical transfers of power with successive elections. Yet, despite its importance, little research considers tolerance outside established democracies. In this paper, we compare political tolerance across eight Eastern European countries and six Western countries. We demonstrate that mean levels of tolerance are lower in the newly democratized countries of Eastern Europe and then examine whether they are a function of East Europeans’ limited experience with democracy. We also test whether established individual-level theories of tolerance replicate across this wide range of new and old democracies. We find some support for theories of democratic learning and also show that models of tolerance operate differently across the range of countries in our sample.

An Alternative Approach to Estimating Who is Most Likely to Respond to Changes in Registration Laws

Scholars often seek to understand which individuals are most responsive to the change in some treatment. Such work inevitably faces issues of identification. When the dependent variable is binary, the assumption that the largest effect occurs where p = 0.5 is also encountered. I apply Manski’s [(1995). Identification problems in the social sciences. Cambridge: Harvard University Press] non-parametric Bounds approach, which relaxes the functional form and distributional assumptions found in traditional models, in an attempt to resolve the long standing debate on which types of individuals are most affected by changes in registration laws. Under the standard assumption that treats the selection of registration laws as exogenous, the results revise the current understanding. By exploring the power of various behavioral assumptions, new insights into the study of policy changes emerge, calling into question some of the assumptions that are standard in the literature.

Media Priming in a Multi-Party Context: A Controlled Naturalistic Study in Political Communication

This study investigates media priming effects in the context of a Summit meeting of European Union (EU) leaders. It differs in four ways from most previous non-experimental priming studies: (1) it provides survey data accompanied by a content analysis of the news, (2) it compares priming effects on evaluations of a number of political leaders, who differed in their visibility in the news, (3) it involves an issue with low salience, and (4) it studies priming effects in the context of a European Parliamentary democracy. The study involves a two-wave panel study (before and after the Summit) on a representative sample of 817 Dutch adults, and a content analysis of the newspaper and television news in the 8 weeks leading up to the Summit meeting. The study shows that media priming effects occur only for the politicians who appeared visible in the news in connection with the issue. The media priming effects were not significantly moderated by political attentiveness or by political knowledge. We also explore the aggregate level consequences of priming for the popularity of leaders, and demonstrate that, as a result of media priming, two politicians became more popular, despite having received a bad press.

Biotechnology and the Modern Liberal Project

Biotechnological enhancement of human capabilities reveals a characteristically modern stance toward nature: Human nature, as given, is an impediment to be overcome on the way to full human freedom. As a form of metaphysical partisanship, the biotech enterprise seems to further the political intention of Thomas Hobbes to nullify human diversity. Commerce in biotech enhancements, and the individual liberty such commerce instantiates, is likely to have the ironic effect of psychic homogenization.
