The color line is still a central problem in the United States, as Du Bois declared more than a century ago. But economic, demographic, and social trends have subdivided it in ways that Du Bois could not have foreseen, creating tremendous intra-ethnoracial group diversity. A challenge for twenty-first-century scholarship is to make sense of the implications of growing intra-group diversity for ...

Scalability is a fundamental problem for information systems when the amount of managed data increases. Peer to Peer systems are usually used to solve scalability problems as centralized approaches do not scale without large dedicated infrastructure. But most current Peer to Peer systems do not take into account that indexed data can be dynamic and change their values very often. Thus, we propo...

Contemporary mobile platforms use software governors to achieve high performance with energy-efficiency for heterogeneous CPU-GPU based architectures that execute mobile games and other graphics-intensive applications. Mobile games typically exhibit inherent behavioral dynamism, which existing governor policies are unable to exploit effectively to manage CPU/GPU DVFS policies. To overcome this ...

Structured peer-to-peer (P2P) overlay networks like Distributed Hash Tables (DHTs) map data items to the network based on a consistent hashing function. Such mapping for data distribution has an inherent load balance problem. Thus, a load balancing mechanism is an indispensable part of a structured P2P overlay network for high performance. The rapid development of P2P systems has posed challeng...

The multiple vehicle routing problem with time windows (VRPTW) is a hard and extensively studied combinatorial optimization problem. This paper considers a dynamic VRPTW with stochastic customers, where the goal is to maximize the number of serviced customers. It presents a multiple scenario approach (MSA) that continuously generates routing plans for scenarios including known and future reques...

This study seeks to understand the underlying mechanisms through which knowledge management (KM) influences organizational performance based on the concept of KM capability. It is proposed that organizational and human resources moderate the effects of physical resources on KM capability. The effect of KM capability under environmental dynamism is also examined. Recognizing that public organiza...

Improving banks performance is important for investors, creditors and other stakeholders. IT as a strategic resource can help bank managers to gain competitive advantage by improving banks’ capabilities. The aim of this study is to investigate the impact of IT and two other variables on firm performance considering the moderating role of environmental dynamism and strategy. IT costs, number of ...
