Media, Information and Development in Papua New Guinea is one of the most interesting books I have on Pacific media. It is a collection of different writers, some of whom are current or former journalists. Several of the authors have direct media links as staff working with the Divine Word University in Madang, a private Christian institution. For the uninitiated, the opening chapter gives an outline of the media landscape in PNG. Other chapters explore media ownership, journalism education and the role of media national development.

PurposeTaking a communication perspective, the paper explores management's rhetoric in profit warnings, whose sole purpose is to disclose unexpected bad news.Design/methodology/approachAdopting a close-reading approach to text analysis, the authors analyse three profit warnings of the now-collapsed Carillion, contrasting the rhetoric with contemporaneous investor conference calls to discuss the profit warnings and board minutes recording boardroom discussions of the case company's precarious financial circumstances. The analysis applies an Aristotelian framework, focussing on logos (appealing to logic and reason), ethos (appealing to authority) and pathos (appealing to emotion) to examine how Carillion's board and management used language to persuade shareholders concerning the company's adverse circumstances.FindingsAs non-routine communications, the language in profit warnings displays and mimics characteristics of routine communications by appealing primarily to logos (logic and reason). The rhetorical profiles of investor conference calls and board meeting minutes differ from profit warnings, suggesting a different version of the story behind the scenes. The authors frame the three profit warnings as representing three stages of communication as follows: denial, defiance and desperation and, for our case company, ultimately, culminating in defeat.Research limitations/implicationsThe research is limited to the study of profit warnings in one case company.Originality/valueThe paper views profit warnings as a communication artefact and examines the rhetoric in these corporate documents to elucidate their key features. The paper provides novel insights into the role of profit warnings as a corporate communication vehicle/genre delivering bad news.

We study the information sensitivity of government debt denominated in domestic versus foreign currency: the former is subject to inflation risk and the latter to default. Default only affects sophisticated bond traders, whereas inflation concerns a larger and less informed group. Within a two-period Bayesian trading game, differential information manifests itself in the secondary market, and we display conditions under which debt prices are more resilient to bad news even in the primary market, where only sophisticated players operate. Our results can explain debt prices across countries following the 2008 financial crisis, and also provide a theory of “original sin.” (JEL D84, F34, H63)

All previous reports on the phenomenon of flashbulb memories relate to hearing of shocking (or “bad”) news; in other words, that of negative affect. This study represents the first attempt to investigate whether those criteria used to define flashbulb memories would similarly apply to events of similar strength but of positive affect. 70 questionnaires were administered relating to 20 events over a 10-yr. period. No significant differences were found on the cardinal features of flashbulb memories for events of negative versus positive affect. This suggests that an hitherto untapped research area may be explored to clarify controversial issues within this construct such as whether a special mechanism exists in the formation of flashbulb memories.

The impregnation of a PILC with carboxylate groups is proposed as a means to improve the adsorption properties of the material for strontium ions. The role of solution pH and carboxylate acid strength in the functionalization of the organic groups is probed by base titrations. In comparing the pristine-PILC with PILCs carrying either oxalate or acetate impregnates, enhanced strontium uptake is evidenced by the modified solids, initiated at pH 6 and 8 in the presence of oxalate and acetate, respectively. The effect on uptake is higher in the former case, amounting to an increase in strontium adsorption by a factor between two and three, depending on the pH range. To further elucidate the significance of the carboxylate acid strength in cation uptake phenomena, strontium adsorption isotherms are presented for PILCs carrying acetate, oxalate, malonate and citrate groups. The results demonstrate that, at constant pH, adsorption increases with increasing acid strength
