1 Recently, Hadoop, an open source implementation of MapReduce, has become very popular due to its characteristics such as simple programming syntax, and its support for distributed computing and fault tolerance. Although Hadoop is able to automatically reschedule failed tasks, it is powerless to deal with tasks with poor performance. Managing such tasks is vital as they lower the whole job's p...

introduction Over the years, trust has been extensively studied in many fields such as sociology, psychology, and economics. The sociologist Gambetta (2000) states that trust is one of the most important social concepts present in all human interaction and without it there is no cooperation or society. Berscheid (1994) also claims that trust is central to how we interact with each other; thus, ...

universal across cultures and is documented in many ethnographic studies. Khalifa &Hardie assert that possession states can be understood only through a combination of biological, anthropological, sociological, psychopathological and experimental perspectives. Psychiatrist and anthropologist Roland Littlewood sees possession as the belief that an individual has been entered by an alien spirit o...

The exploitation of already deployed wireless local area networks (WLAN)s (e.g., WiFi access points (AP)s) has attracted considerable attention, as an efficient and practical method to improve the performance of beyond 4G wireless networks. In this paper, we propose a novel communication paradigm to satisfy the performance demands of future wireless networks: a hybrid Cellular/WLAN network arch...

1. INTRODUCTION Group Support Systems (GSS) technology, which has been developed over the course of the last dozen years, has been initially researched in laboratory-based experiments. More recently, fieldwork has examined how GSS function in real world environments involving businessmen, diplomats, soldiers and students. GSS were originally designed to support discussion and decision making in...

In a recent volume chronicling the historical evolution of assessment constructs and the way these are operationalised through language tests, Weir (2013b) noted how for much of the 20th century the teaching and testing of reading focused on lower-level processing to extract factual meaning at the clause and sentence level, rather than on higher-level processing to combine and integrate textbas...

Homeostatic property clusters (HPCs) are offered as a way of understanding natural kinds, especially biological species. I review the HPC approach and then discuss an objection by Ereshefsky and Matthen, to the effect that an HPC qua cluster seems ill-fitted as a description of a polymorphic species. The standard response by champions of the HPC approach is to say that all members of a polymorp...
