In the presented article, there are fragments of research done by its authors concerning the evaluation of the quality of a patient’s voice following a surgical procedure in the area surrounding the voice channel.

The objectives of this paper are to: 1) understand the characteristics of manufacturing firms associated with ISO 9000 quality control certification and to assess the support these relationships provide for different explanations of the phenomenon; and 2) use these empirical relationships to identify firms most likely to benefit from technical assistance regarding quality control: i.e., firms w...

This paper asks whether brand extension can serve as a signal of product quality given that it costs less than a new brand. (Existing literature has assumed either that brand extension is cost-neutral or that it costs more.) I show that it can as a Perfect Bayesian Equilibrium, but the argument is unconvincing. For one thing, the separating equilibrium is not unique; a pooling equilibrium also ...

A firm whose profits increase when outsiders believe that it pays high wages may induce its workers to over-consume goods that signal high compensation. One implication is that firms may lobby government to subsidize fringe benefits with high signaling value, such as company cars, to their employees. We show that under plausible conditions the provision of fringe benefits indeed can signal the ...

Signal Quality Monitoring (SQM) algorithms propose to detect anomalous GPS signal distortions primarily through the use of multicorrelator SQM receivers. However, currently no augmentation systems (e.g., WAAS or LAAS) have true, real-time SQM capabilities. Still, these systems introduce complexities such as multiple-receiver processing, stringent detection requirements, and potential hardware f...

Net analyte signal statistical quality control (NAS-SQC) is a new methodology to perform multivariate product quality monitoring based on the net analyte signal approach. The main advantage of NAS-SQC is that the systematic variation in the product due to the analyte (or property) of interest is separated from the remaining systematic variation due to all other compounds in the matrix. This enh...

Electroencephalogram (EEG) registration as a direct measure of brain activity has unique potentials. It is one of the most reliable and predicative indicators when studying human cognition, evaluating a subject's health condition, or monitoring their mental state. Unfortunately, standard signal acquisition procedures limit the usability of EEG devices and narrow their application outside the la...

This paper considers a new-product firm’s choice between exporting and foreign direct investment (FDI) to access foreign markets. We find that, when quality is unknown to buyers, the firm may choose FDI over exporting to signal quality, even though FDI is a costlier mode of access than exporting. We then use the model to study the effect of local labor requirement policy imposed by the host cou...

We characterize the optimal procurement contract in a setting where a supplier has privileged knowledge of the quality of a public signal about his production costs. The optimal contract exhibits important differences with standard contracts in adverse selection settings. For instance, the contract induces output both above and below first-best levels. Furthermore, the induced output may not va...

This study extends the understanding of signaling in online shopping environments by evaluating website signal perceptions of online buyers. Drawing from signaling theory, this study proposes and empirically tests a model for conceptualizing the influence of website signal perceptions on perceived trust, perceived deception and purchase intentions. Experimental results support the assertions of...
