Whether all the Platonic dialogues are parts of an inconsistent or consistent body is a controversial subject of philosophy. Indeed, though in form all the texts are written dialogically, in content, one might recognize methodological alterations in Platonic thought from the 1st book of The Republic to later dialogues such as The Statesman and The Laws. However, how much this methodological alteration might affect the content of Plato’s political philosophy, the relation between the rupture in the method of contemplation on (...) the one hand and the structure of the Platonic ideal Polis is still a subject not seriously explored yet. Exploring the characteristics of the three different methods used in Plato’s different dialogues, the present study attempts to show that in the light of the methodological alteration, one might realize how Platonic understanding of the good society has changed from The Republic to The Statesman and The Laws.

Because ports are considered to be the heart of the maritime transportation system, thereby assessing port performance is necessary for a nation’s development and economic success. This study proposes a novel metric, namely, “_port performance index (PPI)_”, to determine the overall performance and utilization of inland waterway ports based on six criteria,_ port facility, port availability, port economics, port service, port connectivity, and port environment_. Unlike existing literature, which mainly ranks ports based on quantitative factors, this study utilizes a Bayesian (...) Network (BN) model that focuses on both quantitative and qualitative factors to rank a port. The assessment of inland waterway port performance is further analyzed based on different advanced techniques such as sensitivity analysis and belief propagation. Insights drawn from the study show that all the six criteria are necessary to predict PPI. The study also showed that port service has the highest impact while port economics has the lowest impact among the six criteria on PPI for inland waterway ports. (shrink)
