Status Competition and Territorial Aggression: Evidence from the Scramble for Africa

When are states willing to engage in behaviors of little material or strategic value in order to assert their status? This article demonstrates that states are more likely to engage in acts of status assertion if their international standing has been called into question. Such status-challenged states seek opportunities to demonstrate their capabilities as well as their intention to maintain their current status. Status assertions often challenge the status and security of other states, leading these states to engage in more frequent acts of aggression. Evidence for these claims comes from detailed analysis of the Scramble for Africa at the end of the nineteenth century. France and Germany adopted expansionary policies in Africa because their great power status had been called into question. These policy shifts directly led Italy and Britain to adopt expansionary policies, leading to the eventual conquest of 95 percent of the African continent.     

Validation of the Seratec® SeraQuant™ for the quantitation of prostate-specific antigen levels on immunochromatographic membranes

Abstract: Use of immunochromatographic membranes for the detection of prostate‐specific antigen (PSA) has become commonplace in forensic laboratories. Experiments were designed to test the newly developed Seratec^® SeraQuant? for accuracy, precision, and consistency in the quantitation of PSA. PSA standards were diluted with buffers and run on the instruments. Values obtained were examined for accuracy (was the correct value obtained?) and precision (were multiple sample values consistent?). To test for variation between instruments, large volumes of diluted PSA standard were run repeatedly on six units and the values obtained were plotted against the known PSA values to obtain a standard curve for each instrument. Fifty membranes having negative or weak positive results were then run on the six units, and the adjusted values were recorded and compared. Results of these experiments indicate that the instruments are accurate and precise in the quantitation of low levels of PSA.     

Colloquy: Political Communication Scholarship in France

Undoubtedly, framing political issues is an effective means of influencing the distribution of opinion. But while most studies have shown the effectiveness of alternative issue frames on opinion, they largely ignore the role of the messenger. Our research examines whether message content or messengers are more important in influencing opinion. Four experimental conditions and a control were embedded in a statewide survey, allowing an explicit comparison between the impact of frames comprising message content alone and the same frames attributed to public figures identified with physician-assisted suicide. Results show that an attributed source is no more effective than content alone in influencing opinion on physician-assisted suicide and that the messenger might in fact reduce the intended influence of the message. We conclude with a discussion of our findings within the larger literature on political persuasion and attitude change.     

Thrombotic thrombocytopenic purpura causing sudden, unexpected death--a series of eight patients

Eight patients were presented to the medical examiner after dying suddenly and unexpectedly from thrombotic thrombocytopenic purpura. Compared with patients who die after prolonged hospitalization and treatment, these patients showed fewer neurologic symptoms and correspondingly fewer or no microthrombi within the brain. Only four of eight subjects developed fever, which further contributed to misdiagnosis. The differences in clinical presentation between our cases and most published series is striking and may be explained by shorter duration and no treatment. Each case contained the characteristic histology of thrombotic thrombocytopenic purpura. Ischemic injury to the heart and conduction system was the most likely mechanism of sudden death. Included in this series is a patient with acquired immunodeficiency syndrome (AIDS) diagnosed at autopsy, a concurrence that is now appearing more frequently in the medical literature.     

The Fifth Wave: The New Tribalism? 1

In political disputes, issue frames set parameters for debate and shape which view dominates. This study expands issue framing research to examine the influence of frames on the perception of future terrorist threats as well as subsequent support for related counterterrorism policies. We test several hypotheses using data from an experimental field poll. We find that issue frames clearly influence perceptions of threat. However, our frames, which posit specific terrorism threats, only have a limited influence on respondent preferences for counter-terrorism policies. We consider a variety of explanations for these results and provide direction for future research.     

The Determinants of Salience of Energy Issues

Studies show that salience of an issue influences the behavior of political elites, policy responses, and the attitudes of the public. Yet while the effects of salience are given considerable attention, less is known about the factors that produce salience. Specifically, what are the determinants of an issue's salience? We examine salience of energy issues in the United States over the past six decades and make two contributions. First, we provide systematic explanations of issue salience. Second, contrary to popular conceptions that energy salience is driven entirely by gasoline prices, or some scholarly analyses that salience depends on crises, we argue that other factors increase salience. Specifically, we find that political actors and activities increase energy salience, even after controlling for higher gas prices and shocks. This is an important finding; political dynamics enhance salience. Meaningful political action, therefore, driven by enhanced salience, is not entirely dependent on market forces or unplanned events.     

The Public Nature of Personal Opinion: The Impact of Collective Sentiment on Individual Appraisal

This paper examines the impact of the public on individual opinion. Employing survey-based experiments, I demonstrate public influence to be considerable, yet the magnitude, direction, and significance of effect depends critically on the target of public sentiment and the political predispositions of the perceiver. A theoretical model is developed to delineate and examine such effects, guiding the analyses throughout. Central to this framework is the interplay between opinion context and individual, reflecting the often fluid and complex relationship between aggregate and individual judgment. The specific findings that representations of public opinion can alter the distribution of opinion through assimilation, contrast, or reinforcement are emphasized and given context within the voting and public opinion literature.     

The Determinants and Consequences of Recall Error About Gulf War Preferences

Memory plays a key role in many theories of politics, yet the determinants of inaccurate political memories have not been the subject of much investigation. Combining a dosage-resistance theory of political communications with a theory of memory lapse and reconstruction, it is predicted that a clearly identifiable cluster of traits ought to render people vulnerable to inaccurate autobiographical memory. Testing this hypothesis with ANES 1990–1992 Gulf War panel data on postwar memories of prewar preferences, the theory receives considerable empirical support. Among other factors, media exposure and trust in government increase vulnerability to misremembering, while education increases resistance. Finally, it is established that inaccuracy in autobiographical memory can be tied to future political behavior: those respondents whose recall was inaccurate in 1991 were more likely to vote for the incumbent in 1992.
