Dynamic integration of context model constraints in web service processes

Autonomic Web service composition has been a challenging topic for some years. The context in which composition takes places determines essential aspects. A context model can provide meaningful composition information for services process composition. An ontology-based approach for context information integration is the basis of a constraint approach to dynamically integrate context validation into service processes. The dynamic integration of context constraints into an orchestrated service process is a necessary direction to achieve autonomic service composition

Context constraint integration and validation in dynamic web service compositions

System architectures that cross organisational boundaries are usually implemented based on Web service technologies due to their inherent interoperability benets. With increasing exibility requirements, such as on-demand service provision, a dynamic approach to service architecture focussing on composition at runtime is needed. The possibility of technical faults, but also violations of functional and semantic constraints require a comprehensive notion of context that captures composition-relevant aspects. Context-aware techniques are consequently required to support constraint validation for dynamic service composition. We present techniques to respond to problems occurring during the execution of dynamically composed Web services implemented in WS-BPEL. A notion of context { covering physical and contractual faults and violations { is used to safeguard composed service executions dynamically. Our aim is to present an architectural framework from an application-oriented perspective, addressing practical considerations of a technical framework

Weaving the Fabric of Patient Safety

It is critical to support Colorado's leaders in health care, business and government to build a culture of safety, ensure safe and efficient transitions of care, and foster the creation of a Patient Safety Organization. This summary -- developed by the Colorado Patient Safety Leadership Task Force with support from The Colorado Trust -- provides a roadmap for patient safety activities in Colorado. The complete agenda, Weaving the Fabric of Patient Safety in Colorado, is available from the Colorado Patient Safety Coalition

Incorporating Security Behaviour into Business Models Using a Model Driven Approach

There has, in recent years, been growing interest in Model Driven Engineering (MDE), in which models are the primary design artifacts and transformations are applied to these models to generate refinements leading to usable implementations over specific platforms. There is also interest in factoring out a number of non-functional aspects, such as security, to provide reusable solutions applicable to a number of different applications. This paper brings these two approaches together, investigating, in particular, the way behaviour from the different sources can be combined and integrated into a single design model. Doing so involves transformations that weave together the constraints from the various aspects and are, as a result, more complex to specify than the linear pipelines of transformations used in most MDE work to date. The approach taken here involves using an aspect model as a template for refining particular patterns in the business model, and the transformations are expressed as graph rewriting rules for both static and behaviour elements of the models

Crime applications and social machines: crowdsourcing sensitive data

The authors explore some issues with the United Kingdom (U.K.) crime reporting and recording systems which currently produce Open Crime Data. The availability of Open Crime Data seems to create a potential data ecosystem which would encourage crowdsourcing, or the creation of social machines, in order to counter some of these issues. While such solutions are enticing, we suggest that in fact the theoretical solution brings to light fairly compelling problems, which highlight some limitations of crowdsourcing as a means of addressing Berners-Lee’s “social constraint.” The authors present a thought experiment – a Gendankenexperiment - in order to explore the implications, both good and bad, of a social machine in such a sensitive space and suggest a Web Science perspective to pick apart the ramifications of this thought experiment as a theoretical approach to the characterisation of social machine

Distributed aspect-oriented service composition for business compliance governance with public service processes

Service-Oriented Architecture (SOA) offers a technical foundation for Enterprise Application Integration and business collaboration through service-based business components. With increasing process outsourcing and cloud computing, enterprises need process-level integration and collaboration (process-oriented) to quickly launch new business processes for new customers and products. However, business processes that cross organisations’ compliance regulation boundaries are still unaddressed. We introduce a distributed aspect-oriented service composition approach, which enables multiple process clients hot-plugging their business compliance models (business rules, fault handling policy, and execution monitor) to BPEL business processes

The Boston Girls Sports & Physical Activity Project: Final Report to the Barr Foundation

The main goal of the three-year Boston Girls' Sports & Physical Activity Project (BGSPAP) was to create an integrated and sustainable network of community-based programs that use sports and physical activity to favorably influence the physical, psychological, and social development of urban girls. The BGSPAP aimed to provide economically disadvantaged urban girls with opportunities to participate in sports and physical activity. The BGSPAP also aspired to upgrade sports and physical activity programming for girls in order to overcome gender biases built into the Boston schools and community programs. The number and quality of sports and exercise programs for Boston girls were not at par with those of Boston boys

She\u27s Sold: Persuading American Women Through Advertising

This study attempted to analyze the effects of an advertising campaign on American women in to illustrate that these women are vastly unaware of just how influential advertising is on their thoughts and actions. It aimed to make women more aware of the presence of advertising in their lives by giving a brief history of the subject, by outlining some current claims in the field, and by introducing a new concept known as shared gender culture. To follow up on secondary research, this study also conducted an experiment on thirty-four women ages eighteen to fifty-five to discover their reactions to a new, never seen advertising campaign for beef. The study attempted to persuade and analyze the effects of persuasion. The study was conducted by survey and asked women their thoughts on and uses of beef before and after revealing the entire print campaign to them. Results showed that half of the participants were not persuaded by the campaign at all through their first and only viewing of it; 26.5% of the women consider themselves entirely invulnerable to advertising persuasion at all. Many women showed great distrust for claims in advertisements, calling them false. Those who did admit to persuasion did so out of a desire to be sexy, happy, healthy, and nurturing to others
