Large-scale online communities rely on computer-mediated communication between participants, enabling them to sustain interactions and exchange on a scale hitherto unknown. Yet, little research has focused on how these online communities sustain themselves and how their interactions are structured. In this paper, we theorize and empirically measure the network exchange patterns of long-duration...

Two versions of a model, named Resource, were developed within the Ensembles with Variable Structure (EVS) approach. The EVS-approach represents interacting groups (populations) with a flexible structure of connections and a diversity of elements (agents), where agents possess an abstract set of characteristics, and seek to form connections with other agents according to the degree of compatibi...

The Self Organizing Map (SOM) involves neural networks, that learns the features of input data thorough unsupervised, competitive neighborhood learning. In the SOM learning algorithm, connection weights in a SOM feature map are initialized at random values, which also sets nodes at random locations in the feature map independent of input data space. The move distance of output nodes increases, ...

We present an architecture that supports provenance queries in large, dynamic, multi-organizational environments. The Provenance Challenges have explored exchange across disparate provenance systems, yet this is only a first step. We describe requirements for multi-organizational provenance, evaluate candidate architectures, describe the approach implemented in the PLUS prototype provenance man...

This study, by using various dimensions of customer satisfaction, investigates and compares the level of customer satisfaction between two leading telecom companies of Bangladesh, Grameen Phone Ltd (GP) and Robi. To collect the primary data, a structured questionnaire was designed and administered on 400 samples comprising of the existing subscribers of both the companies. Results show that in ...

In today’s rapidly changing and increasingly complex environment, organizations have relied on their members’ positive attitude toward their employers. In particular, employees’ organizational commitment (primarily, the affective component) has been recognized as an essential component of organizational functioning and success. Hence, identifying the determinants of affective commitment is one ...

In this work we present a methodology that maps a tree data structure in a nested sets organization; the aim of this methodology is to provide an effective and efficient way to manage and exchange descriptive archival metadata in a distributed environment. We consider archival metadata as a basis for our study because of their challenging nature and the management and exchange difficulties they...

Energy efficiency is one of the top priorities for future cellular networks, which could be accomplished by implementing cooperative mechanisms. In this paper, we propose three eNB-centric energy saving cooperation techniques for LTE systems. These techniques named as intra-network, inter-network and joint cooperation, involve traffic-aware intelligent cooperation among eNBs belong to the same ...

With increasing globalization and loosely-coupled business relations between different companies, the importance of information exchange standards is increasing. GS1’s Electronic Product Code Information Services (EPCIS) is currently one of the main standards proposed for interorganizational data exchange for trace and track purposes in the supply chain. However, some parts of the EPCIS framewo...
