Mashup indices of development

Countries are increasingly being ranked by some new"mashup index of development,"defined as a composite index for which existing theory and practice provides little or no guidance to its design. Thus the index has an unusually large number of moving parts, which the producer is essentially free to set. The parsimony of these indices is often appealing -- collapsing multiple dimensions into just one, yielding unambiguous country rankings, and possibly reducing concerns about measurement errors in the component series. But the meaning, interpretation and robustness of these indices are often unclear. If they are to be properly understood and used, more attention needs to be given to their conceptual foundations, the tradeoffs they embody, the contextual factors relevant to country performance, and the sensitivity of the implied rankings to changing the data and weights. In short, clearer warning signs are needed for users. But even then, nagging doubts remain about the value-added of mashup indices, and their policy relevance, relative to the"dashboard"alternative of monitoring the components separately. Future progress in devising useful new composite indices of development will require that theory catches up with measurement practice.Economic Theory&Research,Information Security&Privacy,Governance Indicators,Health Monitoring&Evaluation,Debt Markets

Privacy-aware Linked Widgets

The European General Data Protection Regulation (GDPR) brings new challenges for companies, who must demonstrate that their systems and business processes comply with usage constraints specified by data subjects. However, due to the lack of standards, tools, and best practices, many organizations struggle to adapt their infrastructure and processes to ensure and demonstrate that all data processing is in compliance with users' given consent. The SPECIAL EU H2020 project has developed vocabularies that can formally describe data subjects' given consent as well as methods that use this description to automatically determine whether processing of the data according to a given policy is compliant with the given consent. Whereas this makes it possible to determine whether processing was compliant or not, integration of the approach into existing line of business applications and ex-ante compliance checking remains an open challenge. In this short paper, we demonstrate how the SPECIAL consent and compliance framework can be integrated into Linked Widgets, a mashup platform, in order to support privacy-aware ad-hoc integration of personal data. The resulting environment makes it possible to create data integration and processing workflows out of components that inherently respect usage policies of the data that is being processed and are able to demonstrate compliance. We provide an overview of the necessary meta data and orchestration towards a privacy-aware linked data mashup platform that automatically respects subjects' given consents. The evaluation results show the potential of our approach for ex-ante usage policy compliance checking within the Linked Widgets Platforms and beyond

Guiding Situational Applications from a Structuration Perspective

Situational applications are a new breed of software assumed to fit to the types of tasks and contextual requirements encountered in dynamic work environments described as weakly structured, highly diverse and fast-changing. The aim of this paper is to discuss the characteristics of situational applications and how organizations can benefit from them with the help of Structuration Theory. Concepts from Structuration Theory allow us to differentiate situational applications from traditionally developed business applications according to the specifics of design and development, the resulting product as well as its deployment and usage. Theoretical implications of this discussion are a much more concise description of situational applications and a host of potential research avenues to further explore research questions on situational applications while managerial implications not only call for creating an organizational and technological infrastructure in support of situational applications, but also for guidance of these grassroots approaches to software development and use

Human system interaction with confident computing

This keynote will give an overview of the last 30 years of human system interaction and the key elements of Human Computer Interaction (HCI) and its transition from traditional HCI into the frontier of Human System Interaction (HSI). This leads to the discussion as to why HSI is about Digital Ecosystems and about the world we live in rather than just ICT. We explain the 5 Mega Trends, and the emergence of Confident Computing and how that is leading to the revolution of the next generation of Human System Interaction version 2.0 and Usability version 2.0. This is followed by the challenges and research issues within Human System Interaction (HSI)

Introducing a Mashup-Based Approach for Design-Time Compliance Checking in Business Processes

Business process compliance tries to ensure the business processes used in an organization are designed and executed according to the rules that govern the company. However, the nature of rules (expressed in natural language) and the large amount of elements that can be involved in them make their materialization and automated checking quite difficult. That is why the existing support for compliance checking is generally restricted to specific kinds of rules (e.g. rules affecting the control flow of the process). in this paper, we introduce compliance mashups, and show how a mashup-based approach can help solve the problem of rule specification and checking at design time. Some advantages of such an approach are that: (i) any kind of rule can be specified, which implies that each user can specify a rule according to his/her interpretation of the rule; (ii) building the compliance mashup is transparent to the formalism(s) used to implement it, so different techniques can be used together; and (iv) mashup components or parts of them can be re-used. As an example we use this approach to build mashups to specify and check rules related to human resource management in business processes at design time

Web Mashups in the Supply Chain

Many supply chains include multiple parties with the goods exchanged several times from the time of their production until they are sold. The liability issues that arise from goods changing hands several times along the way, as well as the exporting and importing regulations that have to be considered, add considerable complexity to the system. Furthermore weather, traffic, and market fluctuations make supply chains less reliable. Many of these issues in supply chain management could be solved or their adverse effects lessened by having information more readily shared among parties. Using Web 2.0 technologies such as a Service-Oriented Architecture, web mashups, blogs, wikis, and social networking sites could be used to facilitate sharing information between parties in a supply chain. This paper focuses on analyzing the potential use of web mashups by enterprises in the supply chain industry. Web mashups, the supply chain, and the security implications of using web mashups in the supply chain are analyzed to determine if it would be worthwhile to use web mashups in the supply chain industry

VALUE IN THE MASH: EXPLORING THE BENEFITS, BARRIERS AND ENABLERS OF OPEN DATA APPS

The open government paradigm relies on the provision and reuse of open government data (OGD) to improve transparency and create new sources of valu. This study aims to progress understanding of OGD beyond a theoretical commentary by exploring the perceived sources of valu of mashups (online services that combine diverse OGD), and to examine issus that impact on, and facilitate, the delivery of this valu from an ˜insider´ perspective. Based on open-ended interviews with 17 individuals actively involved in OGD application design, use, and advocacy in New Zealand (ranked fourth in the 2013 Global Open Data Barometer) nine key sources of valu were identified: Ease of discovery, improved data quality, bringing knowledge into relevant contexts, economic benefits, social benefits, cost reduction and efficiencies, predictive valu, transparency, and ability to explore and play. Twelve barriers to delivering this valu were found, ranging from change-related issus to problems relating to sustainability. Six facilitators were identified as helping to overcome these barriers and realise the valu of OGD

Enhancement of the usability of SOA services for novice users

Recently, the automation of service integration has provided a significant advantage in delivering services to novice users. This art of integrating various services is known as Service Composition and its main purpose is to simplify the development process for web applications and facilitates reuse of services. It is one of the paradigms that enables services to end-users (i.e.service provisioning) through the outsourcing of web contents and it requires users to share and reuse services in more collaborative ways. Most service composers are effective at enabling integration of web contents, but they do not enable universal access across different groups of users. This is because, the currently existing content aggregators require complex interactions in order to create web applications (e.g., Web Service Business Process Execution Language (WS-BPEL)) as a result not all users are able to use such web tools. This trend demands changes in the web tools that end-users use to gain and share information, hence this research uses Mashups as a service composition technique to allow novice users to integrate publicly available Service Oriented Architecture (SOA) services, where there is a minimal active web application development. Mashups being the platforms that integrate disparate web Application Programming Interfaces (APIs) to create user defined web applications; presents a great opportunity for service provisioning. However, their usability for novice users remains invalidated since Mashup tools are not easy to use they require basic programming skills which makes the process of designing and creating Mashups difficult. This is because Mashup tools access heterogeneous web contents using public web APIs and the process of integrating them become complex since web APIs are tailored by different vendors. Moreover, the design of Mashup editors is unnecessary complex; as a result, users do not know where to start when creating Mashups. This research address the gap between Mashup tools and usability by the designing and implementing a semantically enriched Mashup tool to discover, annotate and compose APIs to improve the utilization of SOA services by novice users. The researchers conducted an analysis of the already existing Mashup tools to identify challenges and weaknesses experienced by novice Mashup users. The findings from the requirement analysis formulated the system usability requirements that informed the design and implementation of the proposed Mashup tool. The proposed architecture addressed three layers: composition, annotation and discovery. The researchers developed a simple Mashup tool referred to as soa-Services Provisioner (SerPro) that allowed novice users to create web application flexibly. Its usability and effectiveness was validated. The proposed Mashup tool enhanced the usability of SOA services, since data analysis and results showed that it was usable to novice users by scoring a System Usability Scale (SUS) score of 72.08. Furthermore, this research discusses the research limitations and future work for further improvements
