Understanding Outsourcing Commitment—An Integrated Model Combining The Resoruce-Based View And Knowledge Management
The understanding on how a service provider’s (SP) process capabilities, in terms of aligning and adapting resources to deliver value to its service recipient (SR) in business process outsourcing (BPO), affect its commitment is limited. To address this, building on a strategic perspective and related theories such as the resource-based view and knowledge management, we develop a theoretical model and test it empirically. Specifically, we posit that a SP’s process capabilities, in terms of process alignment, offering flexibility, and partnering flexibility, positively affect its SR’s commitment and the above relationships is negatively moderated by the SR’s behavior control. Besides, we also examine the influence of interaction effect between antecedents of process capabilities on commitment, such as how does process alignment interact with its partnering flexibility and offering flexibility to affect commitment. Finally, we assess whether process capabilities are influenced by the SR’s absorptive capacity and the SP’s task-knowledge coordination. We test our model using survey data collected from 183 firms, supporting most proposed hypotheses. We discuss the theoretical and practical implications of how to increase the value offered to a SR by levering resources, in terms of process capabilities and knowledge management
Space Net Optimization
Most metaheuristic algorithms rely on a few searched solutions to guide later
searches during the convergence process for a simple reason: the limited
computing resource of a computer makes it impossible to retain all the searched
solutions. This also reveals that each search of most metaheuristic algorithms
is just like a ballpark guess. To help address this issue, we present a novel
metaheuristic algorithm called space net optimization (SNO). It is equipped
with a new mechanism called space net; thus, making it possible for a
metaheuristic algorithm to use most information provided by all searched
solutions to depict the landscape of the solution space. With the space net, a
metaheuristic algorithm is kind of like having a ``vision'' on the solution
space. Simulation results show that SNO outperforms all the other metaheuristic
algorithms compared in this study for a set of well-known single objective
bound constrained problems in most cases.Comment: 12 pages, 6 figure
DEXON: A Highly Scalable, Decentralized DAG-Based Consensus Algorithm
A blockchain system is a replicated state machine that must be fault
tolerant. When designing a blockchain system, there is usually a trade-off
between decentralization, scalability, and security. In this paper, we propose
a novel blockchain system, DEXON, which achieves high scalability while
remaining decentralized and robust in the real-world environment. We have two
main contributions. First, we present a highly scalable sharding framework for
blockchain. This framework takes an arbitrary number of single chains and
transforms them into the \textit{blocklattice} data structure, enabling
\textit{high scalability} and \textit{low transaction confirmation latency}
with asymptotically optimal communication overhead. Second, we propose a
single-chain protocol based on our novel verifiable random function and a new
Byzantine agreement that achieves high decentralization and low latency
UNDERSTANDING COMPETITIVE PERFORMANCE OF SOFTWARE-AS-A-SERVICE (SAAS)—THE COMPETITIVE DYNAMICS PERSPECTIVE
Understanding the antecedents and consequences of a firm’s agility in cloud software applications is important. This papers draws on the competitive dynamics perspective to develop a model that explains the relationships between collaboration with vendors, agility, and competitive performance in software-as-a-service (SaaS) context. Collaboration reflects a firm’s ability to leverage interfirm resources, characterized as knowledge sharing and process alignment. Agility is measured by a firm’s strategy-oriented agility and service-oriented agility. This study also investigates the moderating effect of environmental turbulence. The proposed hypotheses are supported by the empirical data. The results show that competitive performance is affected by ability, which, in turn, is impacted by collaboration. Environmental turbulence positively moderates the relationship between agility and performance. Finally, we discuss the implications of our results
Quantum correlation generation capability of experimental processes
Einstein-Podolsky-Rosen (EPR) steering and Bell nonlocality illustrate two
different kinds of correlations predicted by quantum mechanics. They not only
motivate the exploration of the foundation of quantum mechanics, but also serve
as important resources for quantum-information processing in the presence of
untrusted measurement apparatuses. Herein, we introduce a method for
characterizing the creation of EPR steering and Bell nonlocality for dynamical
processes in experiments. We show that the capability of an experimental
process to create quantum correlations can be quantified and identified simply
by preparing separable states as test inputs of the process and then performing
local measurements on single qubits of the corresponding outputs. This finding
enables the construction of objective benchmarks for the two-qubit controlled
operations used to perform universal quantum computation. We demonstrate this
utility by examining the experimental capability of creating quantum
correlations with the controlled-phase operations on the IBM Quantum Experience
and Amazon Braket Rigetti superconducting quantum computers. The results show
that our method provides a useful diagnostic tool for evaluating the primitive
operations of nonclassical correlation creation in noisy intermediate scale
quantum devices.Comment: 5 figures, 3 appendice
