Two and a Half Cheers for the Midwestern Bourgeoisie: Role of the Virtues in Tempering Business Decisions

A recent book (The Bourgeois Virtues: Ethics for an Age of Commerce, D. N. McCloskey), raises the matter of the role of the virtues in business and economic choice, arguing that capitalism can indeed, be virtuous or at least better than the alternative(s). This argument is especially timely in light of the apparent excesses on Wall Street and in some banking/financial institutions. Excessive greed and often the lack of business ethics contributed in substantive ways to the financial crisis and near economic meltdown we have been experiencing. As McCloskey, (2006, pp. 1-2) argues (in setting the stage for the complex argument made in this 616-page book!): “The book … is directed toward you who are suspicious of the phrase ‘bourgeois virtues,’ pretty sure that it is a contradiction in terms. And the book is directed, with less optimism about changing their minds, toward you who think the phrase is worse: a lie. ‘Bourgeois virtues’ is neither. The claim here is that modern capitalism does not need to be offset to be good. Capitalism can on the contrary be virtuous. In a fallen world bourgeois life is not perfect. But it’s better than any available alternative. American capitalism needs to be inspirited, moralized, completed. Two and a half cheers for the Midwestern bourgeoisie (middle-class, small business owners…. yet)… Many a businessman is an ethical shell or worse. Even the virtues of the bourgeoisie, … do not lead straight to heaven.”

Video Quality Assessments on Digital TV and Video Streaming Services Using Objective Metrics

There is a wide range of telecommunications services that transmit voice, video and data through complex transmission networks and in some cases, the service has not an acceptable quality level for the end user. In this sense the study of methods for assessing video quality and voice have a very important role. This paper presents a classification scheme, based on different criteria, of the methods and metrics that are being studied in recent years. This paper presents how the video quality is affected by degradation in the transmission channel in two kinds of services: Digital TV (ISDB-TB) due the fading in the air interface and video streaming service on an IP network due packet loss. For Digital TV tests was set up a scenario where the digital TV transmitter is connected to an RF channel emulator, where are inserted different fading models and at the end, the videos are saved in a mobile device. The tests of streaming video were performed in an isolated scenario of IP network, which are scheduled several network conditions, resulting in different qualities of video reception. The video quality assessment is performed using objective assessment methods: PSNR, SSIM and VQM. The results show how the losses in the transmission channel affects the quality of end-user experience on both services studied.

Dynamic complex formation between HD-GYP, GGDEF and PilZ domain proteins regulates motility in Xanthomonas campestris

RpfG is a member of a class of wide spread bacterial two-component regulators with an HD-GYP cyclic di-GMP phosphodiesterase domain. In the plant pathogen Xanthomonas campestris, RpfG together with the sensor kinase RpfC regulates multiple factors as a response to the cell-to-cell Diffusible Signalling Factor (DSF). A dynamic physical interaction of RpfG with two diguanylate cyclase (GGDEF) domain proteins controls motility. Here we show that, contrary to expectation, regulation of motility by the GGDEF domain proteins does not depend upon their cyclic di-GMP synthetic activity. Furthermore we show that the complex of RpfG and GGDEF domain proteins recruits a specific PilZ domain adaptor protein, and this complex then interacts with the pilus motor proteins PilU and PiIT. The results support a model in which DSF signalling influences motility through the highly regulated dynamic interaction of proteins that affect pilus action. A specific motif that we identify to be required for HD-GYP domain interaction is conserved in a number of GGDEF domain proteins, suggesting that regulation via interdomain interactions is of broad relevance.
