Over the past years, Service-oriented Architecture (SOA) Systems have been recognized more and more as a serious alternative to common monolithic systems for Enterprise Architectures (EA). An SOA provides a flexible means of effectively mapping business processes to IT processes. However, large IT systems require consistent leadership – IT Governance. For SOAs, governance faces new challenges. ...

We explain the importance of conceptual models for process design with service-oriented architectures (SOA) and illustrate how these models can be used to evaluate the value of SOA. To do so, a methodology is introduced, which comprises both the configuration and the implementation of processes by services and IT components. The approach presented here, makes it possible to evaluate the monetar...

This paper examines the use of Service-Oriented Architecture (SOA) services as core assets in a Software product Line (SPL). After a brief introduction to the main concepts of SOA and SPL, the paper identifies a small set of decisions that are required before implementation of SOA-SPL systems. These decisions have to do with 1) the mapping of SOA concepts to the SPL framework, and 2) an initial...

Service-Oriented Architecture (SOA) enables enterprise for distributed and flexible software development. SOA aims at promoting effective software asset reuse by means of encapsulating functionalities as reusable services accessible through well-defined interfaces. However, one of the challenging problems for the realization of this regard is an ever-increasing need for the design and managemen...

Sources, optical properties, and chemical composition of atmospheric brown carbon (BrC) aerosol are uncertain, making it challenging to estimate its contribution to radiative forcing. Furthermore, optical properties of BrC may change significantly during its atmospheric aging. We examined the effect of photolysis on the molecular composition, mass absorption coefficient, and fluorescence of sec...

This paper examines the key managerial factors affecting service-oriented architecture (SOA) implementation in organisations, and whether the implementation of SOA provides benefits to organisations. Based on a cross-sectional survey with 108 organisations, we found that top management support was a significant enabler for SOA implementation. We also found that organisations implementing SOA ga...

Service Oriented Architecture (“SOA”) has been viewed as a strategic approach to IT that provides increased flexibility. However, there is scant research evidence of SOA adoption leading to tangible performance benefits across a cross section of firms. We fill this research gap by empirically analyzing the impact of SOA adoption on the performance of electronic supply chains for a cross section...

Sense of agency (SoA) refers to the feeling that we are in control of our own actions and, through them, events in the outside world. SoA depends partly on retrospectively matching outcomes to expectations, and partly on prospective processes occurring prior to action, notably action selection. To assess the relative contribution of these processes, we factorially varied subliminal priming of a...

In today’s Web environment, service-oriented architecture (SOA) becomes as an efficient paradigm to integrate distributed applications. Due to loosely coupled nature of SOA, security is one of the most important items that must be considered in SOA-based environments. Therefore, providing a comprehensive framework to support security in Enterprise SOA (ESOA) recently becomes a critical issue. I...

Although service-oriented architecture (SOA) is supposed to increase external integration capabilities, it is mostly applied within company boundaries. How companies should apply SOA to improve their inter-organizational relationships is not, as yet, well understood. Although there are several examples of service-oriented concepts in the B2B context, there has been little research in which the ...
