We promote the use of transactional attributes for modelling business processes in the service-oriented scenario. Transactional attributes have been introduced in Enterprise JavaBeans (EJB) to decorate the methods published in Java containers. Attributes describe “modalities” that discipline the reconfiguration of transactional scopes (i.e., of caller and callee) upon method invocation. An orig...

In this paper, we develop and present a contingency model of leadership and psychological empowerment that specifies the circumstances and situations under which follower self-leadership should be encouraged. The model suggests that certain key contingency factors, including follower development, situational urgency and task structure, dictate which of several leadership approaches, including d...

In this paper, we present a Haskell Transactional Memory benchmark in order to provide a comprehensive application suite for the use of Software Transactional Memory (STM) researchers. We develop a framework to profile the execution of the benchmark applications and to collect detailed runtime data on their transactional behavior. Using a composite of the collected raw data, we propose new tran...

a long-standing debate among the vocabulary researchers is the depth of processing to learn vocabulary. this paper is a quantitative research which considers a revision in the “involvement load hypothesis” proposed by laufer and hulstijn in 2001. it investigates the role of proficiency and evaluation in this hypothesis in order to better reveal its potential contribution to vocabulary learning....

We present an analytical performance modeling approach for concurrency control algorithms in the context of Software Transactional Memories (STMs). We consider a realistic execution pattern where each thread alternates the execution of transactional and non-transactional code portions. Our model captures dynamics related to the execution of both (i) transactional read/write memory accesses and ...

hydatid disease is a rare parasitic disease, which mainly involves liver then lung tissues. cardiac involvement is very rare, especially when there is not hepatic involvement. we describe a 47-year-old woman with a history of a lung hydatid cyst who was referred to rajaei heart center, tehran, iran in 2012. her chest computed tomographic scan showed a cardiac mass. echocardiographic examination...

We propose a new design for an energy-efficient hardware transactional memory (HTM) system for power-aware embedded devices. Prior hardware transactional memory designs proposed a small, fully-associative transactional cache at the same level as the L1 cache. We propose an alternative design that unifies the transactional and L1 caches, and provides a small victim cache to reduce effects of cap...
