Bringing the Frame Into Focus: The Influence of Regulatory Fit on Processing Fluency and Persuasion.

Abstract: This research demonstrates that people's goals associated with regulatory focus moderate the effect of message framing on persuasion. The results of 6 experiments show that appeals presented in gain frames are more persuasive when the message is promotion focused, whereas loss-framed appeals are more persuasive when the message is prevention focused. These regulatory focus effects suggesting heightened vigilance against negative outcomes and heightened eagerness toward positive outcomes are replicated when perceived risk is manipulated. Enhanced processing fluency leading to more favorable evaluations in conditions of compatibility appears to underlie these effects. The findings underscore the regulatory fit principle that accounts for the persuasiveness of message framing effects and highlight how processing fluency may contribute to the "feeling right" experience when the strategy of goal pursuit matches one's goal.

Low-temperature fabrication of high-performance metal oxide thin-film electronics via combustion processing

Abstract: Solution-deposited metal oxides show great potential for large-area electronics, but they generally require high annealing temperatures, which are incompatible with flexible polymeric substrates. Combustion processing is now reported as a new low-temperature route for the deposition of diverse metal oxide films, and high-performance transistors are demonstrated using this method.

Risk and Insurance in a Rural Credit Market: An Empirical Investigation in Northern Nigeria

Abstract: Credit contracts play a direct role in pooling risk between households in northern Nigeria. Repayments owed by borrowers depend on realizations of random shocks by both borrowers and lenders. The paper develops two models of state-contingent loans. The first is a competitive equilibrium in perfectly enforceable contracts. The second permits imperfect information and equilibrium default. Estimates of both models indicate that quantitatively important state-contingent payments are embedded in these loan transactions, but that a fully efficient risk-pooling equilibrium is not achieved. The research is based on a year-long survey in Zaria, Nigeria conducted by the author.

Optimum Distribution of Switching Centers in a Communication Network and Some Related Graph Theoretic Problems

Abstract: The concept of a median in a weighted graph is generalized to a multimedian. Then, it is shown that the optimum distribution of p switching centers in a communication network is at a p-median of the corresponding weighted graph. The following related problem in highway networks is also considered: What is a minimum number of policemen that can be distributed in a highway network so that no one is farther away from a policeman than a given distance d? This problem is attacked by generating all vertex-coverings externally stable sets of a graph by means of a Boolean function defined over the vertices of a graph. Then this idea is extended to Boolean functions that generate all matchings, all factors, and all possible subgraphs of G with given degrees.

Development of a test of speech intelligibility in noise using sentence materials with controlled word predictability.

Abstract: This paper describes a test of everyday speech reception, in which a listener’s utilization of the linguistic‐situational information of speech is assessed, and is compared with the utilization of acoustic‐phonetic information. The test items are sentences which are presented in babble‐type noise, and the listener response is the final word in the sentence (the key word) which is always a monosyllabic noun. Two types of sentences are used: high‐predictability items for which the key word is somewhat predictable from the context, and low‐predictability items for which the final word cannot be predicted from the context. Both types are included in several 50‐item forms of the test, which are balanced for intelligibility, key‐word familiarity and predictability, phonetic content, and length. Performance of normally hearing listeners for various signal‐to‐noise ratios shows significantly different functions for low‐ and high‐predictability items. The potential applications of this test, particularly in the assessment of speech reception in the hearing impaired, are discussed.
