Most STM systems are poorly equipped to support libraries of concurrent data structures. One reason is that they typically detect conflicts by tracking transactions’ read sets and write sets, an approach that often leads to false conflicts. A second is that existing data structures and libraries often need to be rewritten from scratch to support transactional conflict detection and rollback. Th...

To allow providers to keep their autonomy and ensure the overall system can run satisfactorily, it is common practice in the Web Services environment for providers to reduce the strength of some of the traditionallyrequired ACID properties when offering transactional support. However, current standards require providers to offer a constant level of transactional support for each operation they ...

The Web services platform offers a distributed computing environment where autonomous applications interact using standard Internet technology. In this environment, diverse applications and systems become the components of intraand inter-enterprise integration. Yet, transactional reliability, an often critical requirement on such integration, is presently missing from the Web services platform....

User queries on the Web can be classified into three types according to user’s intention: informational query, navigational query and transactional query. In this paper, a query type classification method and Service Link information for transactional queries are proposed. Web mediated activity is usually implemented by hyperlinks. Hyperlinks can be good indicators in classifying queries and re...

To enable effective interorganisational collaborations, process providers have to disclose relevant parts of their local business processes in public process views. A public process view has to be consistent with the underlying private process. Local business processes are typically supported by transactions, which ensure a robust and reliable execution. Process views currently do not support t...

The purpose of this research is to examine the relationships between changes to computer selfefficacy (CSE) and computer anxiety and the impact on performance on computer-related tasks in both online and face-to-face mediums. While many studies have looked at these factors individually, relatively few have included multiple measures of these factors concurrently and assessed the effects over a ...

Web services are defined independently of any execution context. Due to their inherent autonomy and heterogeneity, it is difficult to examine the behaviour of composite services, especially in case of failures. This paper is interested in ensuring composite services reliability. Reliable composition is defined as a composition where all instance executions are correct from a transactional and b...

A transactional agent is a mobile agent which manipulates objects in one or more than one object server so as to satisfy some constraints. There are some types of constraints depending on applications. ACID is one of the constraints, which shows traditional atomic transactions. There are other constraints like at-least-one constraint where a transaction can commit if at least one object server ...

BACKGROUND Transactional sex is associated with the HIV epidemic among young people in Uganda. Few quantitative studies based on nationally representative survey data explored the relationship between sexual behaviors, HIV infection, and transactional sex. OBJECTIVE This study aimed to determine the associations between risky sexual behaviors, participation in transactional sex, and HIV sero-...

Transactions provide a language construct that programmers can use to specify that operations execute atomically, in isolation from all computation outside the transaction. Transactions permit optimistic concurrency for accesses to shared data, which may improve performance over locking mechanisms. Transactions also allow programmers to specify atomic regions in a composable way, which locks do...
