Service Oriented Computing (SOC) is a popular computing paradigm for the development of distributed Web applications. Service composition, a key element of SOC, is severely hampered by various types of semantic heterogeneity among the services. In this paper, we address the various semantic...

In the era of Global Services, Service Oriented Architecture (SOA) has been gaining momentum for building Web-based information systems. Service composition is one of the key objectives for adopting SOA. Unfortunately, Web services are not always exactly compatible and it is a non-trivial task...

With the increasing popularity of Service Oriented Architecture (SOA), service composition is gaining momentum as the potential silver bullet for application integration. However, services are not always perfectly compatible and therefore can not be directly composed. Service mediation, roughly...

We present a method for estimating Markov dynamic models with unobserved state variables which can be serially correlated over time. We focus on the case where all the model variables have discrete support. Our estimator is simple to compute because it is noniterative, and involves only...

Issues of international trade policy have gained increased attention while cybersecurity has not been a key issue for trade policy until recently. Cybersecurity concerns have presented significant challenges, and cybersecurity-related allegations have become a major source of growing commercial...

Cyber attacks are increasing in frequency, sophistication, and impact. Defending against them requires a new perspective on the attacks and the attackers. By applying a value-chain lens to the problem, we can better understand the dark web as an ecosystem in which well-orchestrated attacks are...

Cross-border data flows and interoperability have created an increasingly digital global trade environment. Concerns for cybersecurity, privacy, and digital sovereignty have prompted the widespread implementation of trade policies regulating cross-border data flows. At present, there is a...

Cyber risk can underlie the next financial crisis. Increasing trade policies on cross-border financial services have been implemented to manage cybersecurity concerns. Simply complying with the fragmented policies can cause unintended consequences for businesses and can even result in new cyber...

Cybersecurity concern is becoming a key issue for trade policy.Issues of international trade policy have recently gained increased attention. Of course, restrictions on international trade regarding technology have long existed – on imports and exports, as well as on direct foreign investment...
