    Notes: Bimetallic alloys have been considered in terms of their wetting behavior on semiconducting BaTiO3. In an earlier study, wetting behavior was strongly linked to ohmic contact behavior. However, the wetting behavior does not always correlate in the form of high work of adhesion-low contact resistance. The departure from this trend is associated with the nature of the segregation of the solute. Two extreme cases are considered in this study: no driving force for segregation and a strong driving force. These cases are characterized with sessile drop experiments and qualitatively analyzed in terms of thermodynamic analysis, both a surface enrichment model is considered together with an energy diagram approach. Both models give excellent qualitative agreement to the observed wetting behavior of the bimetallic alloy-BaTiO3 system. © 2001 American Institute of Physics.

    Notes: Interest groups seek to influence economic activity through public and private politics. Public politics takes place in the arena of public institutions, whereas private politics takes place outside public institutions often in the arena of public sentiment. Private politics refers to action by interest groups directed at private parties, as in the case of an activist group launching a campaign against a firm. This paper presents a model of informational competition between an activist and an industry, where both interest groups seek to influence public sentiment and do so by advocating their positions through the news media. Citizen consumers make both a private consumption decision and a collective choice on the regulation of a product that has an externality associated with it. In the absence of the news organization, the collective choice is not to regulate. The activist and the industry obtain private, hard information on the seriousness of the externality and provide favorable information to the news media and may conceal unfavorable information. The news media can conduct investigative journalism to obtain its own information, and based on that information and the information it has received from its sources, provides a news report to the public. Because of its role in society, the media has an incentive to bias its report, and the direction of bias is toward regulation. Its bias serves to mitigate both market failure by decreasing demand and a government failure by shifting votes in favor of regulation. The activist then has incentive to conceal information unfavorable to its interests, whereas the industry fully reveals its information.

    Notes: This paper introduces the subject of private politics, presents a research agenda, and provides an example involving activists and a firm. Private politics addresses situations of conflict and their resolution without reliance on the law or government. It encompasses the political competition over entitlements in the status quo, the direct competition for support from the public, bargaining over the resolution of the conflict, and the maintenance of the agreed-to private ordering. The term private means that the parties do not rely on public order, i.e., lawmaking or the courts. The term politics refers to individual and collective action in situations in which people attempt to further their interests by imposing their will on others. Four models of private politics are discussed: (1) informational competition between an activist and a firm for support from the public, (2) decisions by citizen consumers regarding a boycott, (3) bargaining to resolve the boycott, and (4) the choice of an equilibrium private ordering to govern the ongoing conflicting interests of the activist and the firm.

    Notes: This paper presents theories of strategic nonmarket participation in majority-rule and executive institutions and develops from those theories a set of principles for nonmarket strategy. The theories are based on models of vote recruitment in client and interest-group politics and on models of common agency. The basic strategies developed are majority building, vote recruitment, agenda setting, rent-chain mobilization, majority protection, and competitive agenda setting and vote recruitment.

    Notes: This paper provides a theory of private politics in which an activist seeks to change the production practices of a firm for the purpose of redistribution to those whose interests it supports. The source of the activist's influence is the possibility of support for its cause by the public. The paper also addresses the issue of corporate social responsibility by distinguishing among corporate redistribution as motivated by profit maximization, altruism, and threats by the activist. Private politics and corporate social responsibility not only have a direct effect on the costs of the firm, but also have a strategic effect by altering the competitive positions affirms in an industry. From an integrated-strategy perspective the paper investigates the strategic implications of private politics and corporate social responsibility for the strategies of rival firms when one or both are targets of an activist campaign. Implications for empirical analysis are derived from the theory.

    Notes: There is evidence that the oral contraceptive pill (OCP) and smoking contribute independently to risk of circulatory disease. There is mixed evidence that the combined risk may be greater than the sum of these factors operating in isolation. Little is known about how the general population views the risks from OCP use, singly and in combination with smoking. Previous attempts at assessing whether the public views risks as operating synergistically have generally found evidence for subadditive models, where the combined risk is less than the sum of factors operating in isolation. However, concerns have been expressed over the validity of the measures of risk perception used. Therefore, this study used three distinct methods of measurement to assess the extent to which 241 undergraduate students perceive the risks of smoking and the OCP, separately and combined, for circulatory disease. For all three methods, respondents read each of four vignettes describing information about a woman's risk factors (with high and low levels of both OCP and smoking), and then estimated risk of circulatory disease using one of the three risk measures. The three measures produced similar ratings. Consistent with the epidemiological evidence, information about smoking had more impact on estimates of overall risk than did information about the OCP. For all three measures, responses were consistent with an additive model of risk from smoking and the OCP. This convergence of results from different methods suggests that all three methods of measurement employed, which all had a large number of response options, may be valid.

    Notes: Introduction: Dofetilide is the newest drug approved by the United States Food and Drug Administration for the treatment of patients with atrial fibrillation (AF). Few data on the efficacy and safety of dofetilide in a diverse group of patients are available. The aim of this study was to evaluate the results of dofetilide in a consecutive series of 69 patients with AF. Methods and Results: Sixty-nine patients with persistent (n = 53) or paroxysmal (n = 16) AF were administered dofetilide in-hospital. Prior to starting dofetilide, all patients had been adequately anticoagulated, and concomitant agents contraindicated in the presence of dofetilide were discontinued. Heart rhythms were monitored continuously by telemetry in all patients. The initial dose, which was determined using the Cockroft-Gault calculated creatinine clearance, was 500 μg bid, 250 μg bid, and 125 μg bid in 51, 13, and 5 patients, respectively. Reductions in subsequent dosage occurred in 12 patients, 4 for QT prolongation. Dofetilide was discontinued in-hospital in 7 patients, 2 for adverse arrhythmic events and 3 for unacceptable QT prolongation. Twenty-seven (63%) of 43 patients in AF converted spontaneously to sinus rhythm. Fifty-eight patients were discharged receiving dofetilide treatment and were followed as outpatients for 21 ± 7 months. One third of patients continued to take dofetilide at 1 year. One patient had a cardiac arrest 1 day after hospital discharge. Conclusion: Dofetilide is a well-tolerated antiarrhythmic drug with a high conversion rate of AF to sinus rhythm. One third of patients maintained sinus rhythm at 1 year. Proarrhythmia can occur and initiation of therapy must be performed in-hospital.

    Notes: Crystalline mullite was deposited by chemical vapor deposition (CVD) onto SiC/SiC composites overlaid with CVD SiC. Specimens were exposed to isothermal oxidation tests in high-pressure air + H2O at 1200°C. Unprotected CVD SiC formed silica scales with a dense amorphous inner layer and a thick, porous, outer layer of cristobalite. Thin coatings (∼2 μm) of dense CVD mullite effectively suppressed the rapid oxidation of CVD SiC. No microstructural evidence of mullite volatility was observed under these temperature, pressure, and low-flow-rate conditions. Results of this preliminary study indicate that dense, crystalline, high-purity CVD mullite is stable and protective in low-velocity, high-pressure, moisture-containing environments.

    Notes: Chronic cocaine use elicits changes in the pattern of gene expression within reinforcement-related, dopaminergic regions. cDNA hybridization arrays were used to illuminate cocaine-regulated genes in the nucleus accumbens (NAcc) of non-human primates (Macaca fascicularis; cynomolgus macaque), treated daily with escalating doses of cocaine over one year. Changes seen in mRNA levels by hybridization array analysis were confirmed at the level of protein (via specific immunoblots). Significantly up-regulated genes included: protein kinase A α catalytic subunit (PKAcα); cell adhesion tyrosine kinase beta (PYK2); mitogen activated protein kinase kinase 1 (MEK1); and β-catenin. While some of these changes exist in previously described cocaine-responsive models, others are novel to any model of cocaine use. All of these adaptive responses coexist within a signaling scheme that could account for known inductions of genes(e.g. fos and jun proteins, and cyclic AMP response element binding protein) previously shown to be relevant to cocaine's behavioral actions. The complete data set from this experiment has been posted to the newly created Drug and Alcohol Abuse Array Data Consortium () for mining by the general research community.
