I have adapted STAMP benchmarks [1] for use with the MPARM simulator in order to evaluate the performance of transactional cache configurations. We are primarily interested in evaluating energy consumption in multi-core mobile devices. There are two main hardware configurations being evaluated: a simple transactional cache (“vanilla TM”), and a victim cache configuration. In the vanilla configu...

It is generally agreed that one of the key services of componentbased systems are transactions. However, an agreement on how components should be involved in transactions is still missing. In this paper, we discuss some of the key issues of combining components with transactions, and different approaches to achieve an appropriate level of transactional functionality in components. We distinguis...

Transactional memory (TM) systems implement the concept of an atomic execution unit called transaction in order to discharge programmers from explicit synchronization management. But when shared data is atomically accessed by both transaction and non-transactional code, a TM system must provide strong isolation in order to overcome consistency problems. Strong isolation enforces ordering betwee...

Noninjecting illicit drug users (NIDUs) present high risk for HIV infection, due especially to transactional sex. This study aimed to estimate the prevalence and risk factors for transactional sex among NIDUs in the Southwest region of Goiás State, Central Brazil. The prevalence of self-reported transactional sex was 22.8%. Prevalence in women and men was 52.7% and 16.8%, respectively, a signif...

In Service-Oriented Computing (SOC), a business transaction comprises of several web services provided by multiple enterprises. The transactional behaviour of individual web services must be considered for service selection so that the composition of web services results in a reliable execution. It is difficult for a business analyst to envisage the desired business policies of a process in ter...

Understanding search behavior in the context of the larger work task is of key importance in order to build search systems that can assist users in achieving work task completion. This study explores a particular type of task, transactional, that has not received due attention in the literature so far. A total of 38 users were observed in a laboratory experiment where they completed tasks at di...

This study examined whether a transactional interpersonal life stress model helps to explain the continuity in depression over time in girls. Youth (86 girls, 81 boys; M age = 12.41, SD = 1.19) and their caregivers participated in a three-wave longitudinal study. Depression and episodic life stress were assessed with semistructured interviews. Path analysis provided support for a transactional ...

INTRODUCTION Transactional sex is a structural driver of HIV for women and girls in sub-Saharan Africa. In transactional relationships, sexual and economic obligations intertwine and may have positive and negative effects on women's financial standing and social status. We conducted a clinic-based survey with pregnant women in Swaziland using a locally validated transactional sex scale to measu...
