Why not say it directly? The social functions of irony

Abstract: In three experiments, we investigated the social payoffs of speaking ironically. In Experiment 1, participants rated videotaped ironic remarks (criticisms and compliments) as funnier than literal remarks, but no more or less status enhancing. In Experiment 2, participants listened to audiotaped ironic criticisms and compliments. Ironic compliments were rated as more insulting than literal compliments, but ironic criticisms were found to be less insulting than literal criticisms. In Experiment 3, participants read literal or ironic criticisms. Ironic comments were rated as more amusing than literal ones. When irony was directed at the addressee's poor performance, it served to protect the addressee's face by softening the criticism. When irony was directed at the addressee's offensive behavior, it served to protect the speaker's face by showing the speaker as less angry and more in control. In addition, irony damaged the speaker—addressee relationship less than did literal criticism. Taken together, these ...

What Is the True Value of a Lost Customer

Abstract: Customer profitability models have evolved into an important strategic tool for marketers in recent years. Traditional customer profitability models implicitly assume that customers can be valued i...

Understanding Shareholder Activism: Which Corporations are Targeted?

Abstract: This study provides preliminary empirical evidence that shareholder activists target companies because of their size as well as specific stakeholder-related practices. The data show that shareholder activists target companies with shareholder resolutions demanding changes in corporate behaviors for companies producing problematic products and where environmental concerns exist. Furthermore, companies in specific industries are targeted based on poor employee and community-related practices. Activists, that is, are selective in their targeting of companies, choosing the most visible (largest) companies and those whose practices raise specific issues of interest to society.

Laboratory studies of the chemical composition and cloud condensation nuclei (CCN) activity of secondary organic aerosol (SOA) and oxidized primary organic aerosol (OPOA)

Abstract: . Secondary organic aerosol (SOA) and oxidized primary organic aerosol (OPOA) were produced in laboratory experiments from the oxidation of fourteen precursors representing atmospherically relevant biogenic and anthropogenic sources. The SOA and OPOA particles were generated via controlled exposure of precursors to OH radicals and/or O 3 in a Potential Aerosol Mass (PAM) flow reactor over timescales equivalent to 1–20 days of atmospheric aging. Aerosol mass spectra of SOA and OPOA were measured with an Aerodyne aerosol mass spectrometer (AMS). The fraction of AMS signal at m/z = 43 and m/z = 44 ( f 43 , f 44 ), the hydrogen-to-carbon (H/C) ratio, and the oxygen-to-carbon (O/C) ratio of the SOA and OPOA were obtained, which are commonly used to characterize the level of oxidation of oxygenated organic aerosol (OOA). The results show that PAM-generated SOA and OPOA can reproduce and extend the observed f 44 – f 43 composition beyond that of ambient OOA as measured by an AMS. Van Krevelen diagrams showing H/C ratio as a function of O/C ratio suggest an oxidation mechanism involving formation of carboxylic acids concurrent with fragmentation of carbon-carbon bonds. Cloud condensation nuclei (CCN) activity of PAM-generated SOA and OPOA was measured as a function of OH exposure and characterized as a function of O/C ratio. CCN activity of the SOA and OPOA, which was characterized in the form of the hygroscopicity parameter κ org , ranged from 8.4×10 −4 to 0.28 over measured O/C ratios ranging from 0.05 to 1.42. This range of κ org and O/C ratio is significantly wider than has been previously obtained. To first order, the κ org -to-O/C relationship is well represented by a linear function of the form κ org = (0.18±0.04) ×O/C + 0.03, suggesting that a simple, semi-empirical parameterization of OOA hygroscopicity and oxidation level can be defined for use in chemistry and climate models.
