This thesis is an historical analysis of the phenomenon of piracy in the ancient world from the Bronze Age to the Arab conquests. It is based on detailed examination and discussion of the ancient sources. There is a short introduction (Part One) which establishes the scope of the enquiry, defines the subject and surveys modern scholarly literature. Part Two (The Image of Ancient Piracy) consists of a study of the Greek and Latin vocabulary for piracy, and six separate studies of Classical literature, from Homer to the fourth century A.D. These studies analyze the development of the literary image of pirates and piracy, from the ambivalent attitude of the Homeric poems, to the wholly negative presentation of pirates and piracy found in the works of later writers. Part Three (War and Piracy) analyzes the early similarity between warfare and piracy, the gradual emergence of distinctions between the two, warfare as a promoter of piracy, and the involvement of pirates in warfare. Part Four (Trade and Piracy) is an analysis of the relationship between piracy and various forms of trade. The importance of piracy as both a contributor and a threat to long-distance maritime trade is analyzed, as well as the involvement of pirates in the slave trade. The link between trade and the suppression of piracy is also discussed. Part Five (The Suppression of Piracy) examines in detail attempts to suppress piracy from the Classical period to the end of the Roman Empire. Emphasis is laid upon the practical and political implications of suppression, and the relative ineffectiveness of most measures until the Late Republic and Early Principate, when piracy was suppressed with considerable success. There follows a brief statement of the general conclusions (Part Six) and suggestions for further research. One map and a bibliography are included.

The dissertation identifies a body of public policies described as "politically intractable." These are policies which are of clear public benefit, but which involve high political costs to those who enact them. It is suggested that there are two routes to political tractability in the passage of these policies. The "low-risk" strategy entails insulating policy-makers from pressures applied by alienated vested interests. The "high-risk" strategy arises where actors responsible for passing intractable policies risk alienating vested interests if enacting the policy assists them to realize higher-order objectives. These higher-order objectives involve games of institutional design--attempts to reform or preserve (in the face of threat) the institutional structure of the state. The dissertation examines a subset of politically intractable policies called watershed trade policies. Watersheds are instances of substantial trade liberalization which reverse a long-standing tradition of protectionism. The dissertation explains the passage of three watersheds: Britain's repeal of the Corn Laws, the US Reciprocal Trade Agreements Act, and Canada's Free Trade Implementation Act, in the context of the high-risk strategy. In these cases, trade liberalization is explained as a by-product of games of institutional design undertaken by political entrepreneurs within the state.

Trade shows, a powerful tool to introduce and sell products and services, need to attract, hold, persuade and inform visitors. In trade shows, well-designed social spaces can facilitate active communications and interactions between exhibitors and visitors. Besides being amenities to retain visitors, social spaces can balance or re-stimulate visitors’ emotion. Based on the interdisciplinary exploration of urbanism, environmental psychology, and exhibition design, the practicum proposes a new strategy of organization for exhibition layout, structured by social spaces in various scales and levels. Case studies of existing trade shows identify the context and design factors in existing social spaces. The understanding of human behaviour and activities determines an appropriate configuration of social spaces. Systematic programming will delineate the context relating to the practicum topic. The final product is to find appropriate solutions and approachable settings to develop effective social spaces within a public trade show, improving the comprehensive quality of exhibitions.
