Socio-economic aware data forwarding in mobile sensing networks and systems

The vision for smart sustainable cities is one whereby urban sensing is core to optimising city operation which in turn improves citizen contentment. Wireless Sensor Networks are envisioned to become pervasive form of data collection and analysis for smart cities but deployment of millions of inter-connected sensors in a city can be cost-prohibitive. Given the ubiquity and ever-increasing capabilities of sensor-rich mobile devices, Wireless Sensor Networks with Mobile Phones (WSN-MP) provide a highly flexible and ready-made wireless infrastructure for future smart cities. In a WSN-MP, mobile phones not only generate the sensing data but also relay the data using cellular communication or short range opportunistic communication. The largest challenge here is the efficient transmission of potentially huge volumes of sensor data over sometimes meagre or faulty communications networks in a cost-effective way. This thesis investigates distributed data forwarding schemes in three types of WSN-MP: WSN with mobile sinks (WSN-MS), WSN with mobile relays (WSN-HR) and Mobile Phone Sensing Systems (MPSS). For these dynamic WSN-MP, realistic models are established and distributed algorithms are developed for efficient network performance including data routing and forwarding, sensing rate control and and pricing. This thesis also considered realistic urban sensing issues such as economic incentivisation and demonstrates how social network and mobility awareness improves data transmission. Through simulations and real testbed experiments, it is shown that proposed algorithms perform better than state-of-the-art schemes.Open Acces

Nature\u27s Goodness: An Aristotelian Account

Neo-Aristotelians have made major headway in moral theory, and it is now commonplace to find philosophers defending the reality of goodness through a teleological analysis of human being. Whatever the merits of this approach, it has suffered from a lack of a sustained defense of its pre-modern metaphysical panorama: the Aristotelian conception of the human good gets traction only if its decidedly pre-modern and `robust\u27 philosophy of nature is defensible in its own right. In this dissertation, I aim to give a partial breakdown of the particular sort of metaphysical project that the Aristotelian moral theorist assumes, but does not always explicate. In particular, I aim to show how neo-Aristotelians rely on a particular view of substance that, while certainly challenging to contemporary naturalist construals of the same, is nevertheless defensible in its own right. Moreover, it might well be the case that even `liberal\u27 contemporary naturalist construals of `moral facts\u27 face difficulties that cannot be overcome; for they might only be able to countenance the less deflationary moral ontologies they desire by first assuming a view of substance that puts pressure on the entirety of the `modern\u27 project. The first part of this dissertation will focus on the ways that an Aristotelian nature is defensible. The second part will show in more detail how this pre-modern vision of reality helps to locate and in some cases even `solve\u27 certain metaethical conundrums. The goal is to show why an Aristotelian moral theory can offer a credible alternative to the usual `moral realist\u27 positions in contemporary metaethics, by offering not just a more plausible view of human goodness, but a more plausible view of nature as a whole

Lab Labor: What Can Labor Economists Learn from the Lab?

This paper surveys the contributions of laboratory experiments to labor economics. We begin with a discussion of methodological issues: why (and when) is a lab experiment the best approach; how do laboratory experiments compare to field experiments; and what are the main design issues? We then summarize the substantive contributions of laboratory experiments to our understanding of principal-agent interactions, social preferences, union-firm bargaining, arbitration, gender differentials, discrimination, job search, and labor markets more generally.personnel economics, principal-agent theory, laboratory experiments, labor economics
