In this paper we introduce TAS (Transactional Auto Scaler), a system that relies on a novel hybrid analytical/machine-learning-based forecasting methodology in order to accurately predict the performance achievable by transactional applications executing on top of transactional in-memory data stores, in face of changes of the scale of the system. Applications of TAS range from on-line selfoptim...

INTRODUCTION Young women aged 15 to 24 years in sub-Saharan Africa continue to be disproportionately affected by HIV. A growing number of studies have suggested that the practice of transactional sex may in part explain women's heightened risk, but evidence on the association between transactional sex and HIV has not yet been synthesized. We set out to systematically review studies that assess ...

BACKGROUND 'Transactional sex' was regarded by the mid-1990s as an important determinant of HIV transmission, particularly in sub-Saharan Africa. Little attention has been paid to what the terms used to denote transactional sex suggest about how it is understood. This study provides a nuanced set of descriptions of the meaning of transactional sex in three settings. Furthermore, we discuss how ...

BACKGROUND Transactional sex is a risk factor for HIV infection. Alcohol use may increase the risk of transactional sex. No nationally-representative studies have examined the relationship between multiple dimensions of alcohol use and transactional sex in women in South Africa. The aim of the study was to examine the relationship between alcohol dependence, binge drinking and frequency of drin...

Common goal of descriptive data mining techniques is presenting new information in concise, easily interpretable and understandable ways. Hierarchical clustering technique for example enables simple visualization of distances between analyzed objects or attributes. However, common distance measures used by existing data mining tools are usually not well suited for analyzing transactional data u...

This paper proposes a formal framework to statically analyze intensional databases modeling transactional behavior. The considered language is U-Datalog, an extension of Datalog modeling updates and transactions. The analysis, performed at compile time, provides information about certain types of situations that may arise at execution time such as aborts, inconsistencies and failures. These inf...
