Enabling Personalized Composition and Adaptive Provisioning of Web Services

The proliferation of interconnected computing devices is fostering the emergence of environments where Web services made available to mobile users are a commodity. Unfortunately, inherent limitations of mobile devices still hinder the seamless access to Web services, and their use in supporting complex user activities. In this paper, we describe the design and implementation of a distributed, adaptive, and context-aware framework for personalized service composition and provisioning adapted to mobile users. Users specify their preferences by annotating existing process templates, leading to personalized service-based processes. To cater for the possibility of low bandwidth communication channels and frequent disconnections, an execution model is proposed whereby the responsibility of orchestrating personalized processes is spread across the participating services and user agents. In addition, the execution model is adaptive in the sense that the runtime environment is able to detect exceptions and react to them according to a set of rules

Preliminary Results Towards Contract Monitorability

This paper discusses preliminary investigations on the monitorability of contracts for web service descriptions. There are settings where servers do not guarantee statically whether they satisfy some specified contract, which forces the client (i.e., the entity interacting with the server) to perform dynamic checks. This scenario may be viewed as an instance of Runtime Verification, where a pertinent question is whether contracts can be monitored for adequately at runtime, otherwise stated as the monitorability of contracts. We consider a simple language of finitary contracts describing both clients and servers, and develop a formal framework that describes server contract monitoring. We define monitor properties that potentially contribute towards a comprehensive notion of contract monitorability and show that our simple contract language satisfies these properties.Comment: In Proceedings PrePost 2016, arXiv:1605.0809

Open Access and the REF: Issues and Potential Solutions Workshop: Executive Summary

This report provides a summary of the discussion and findings of the Open Access and the REF: Issues and Potential Solutions workshop held as part of the End-to-End Project. The workshop was highly interactive and feedback received indicated it was considered an excellent event, and that it was vital and useful to bring together various key stakeholders to discuss problems and procedures and develop ideas

SDGs and Human Rights: how to measure States’ compliance?

In September 2015 UN General Assembly approved the SDGs and all over the world the expectations focused on the new UN Development Agenda. Apparently, issues concerning Human Rights and Human security, including absence of violence, promotion of sustainable peace and accountable institutions, have been strongly taken into account during negotiations. From this perspective, the SDGs go far beyond MDGs while acknowledging a deep connection with human development. Nonetheless, the references made to human rights law in the final document are weak and fragmented. Moreover, the SDG 16, focused on security andpromotion of the rule of law, is not time- bound and does not include clear indicators related to its targets. In the light of this, the main objective of this paper is to analyse the grade of real recognition of human rights and security issues in the Post- 2015 Agenda and to suggest possible indicators for SDG 16 targets based on juridical instruments. For this reason connections between SDGs and existing human rights binding norms will be assessed in order to demonstrate how the inclusion of explicit references to core treaties in the above- mentioned indicators could promote a more effective monitoring

The NLRB’s Social Media Guidelines a Lose-Lose: Why the NLRB’s Stance on Social Media Fails to Fully Address Employer’s Concerns and Dilutes Employee Protections

[Excerpt] The expanding use of both personal and professional social media sites has resulted in its growing impact in the workplace. Recently, many examples have emerged where an individual’s use of social media for communicating frustrations or sharing personal information resulted in significant conflict between the individual and their employer. Employment actions arising from an employee’s social media use have become so contentious that a number of employers have been charged with unfair labor practices for overly broad social media policies or implementation of unfair policies. Following several important Board decisions the NLRB issued guidelines, identifying acceptable employer-initiated social media policies. As social media’s popularity will likely only continue to grow, it is important to understand how employer policies impact employees’ social media use and the potential invasion these policies may have on employees’ rights. This article concludes that the NLRB’s issued guidance fails to adequately address social media concerns raised by employers and dilutes employees’ rights to communicate workplace concerns. This is because even though the guidance permits employer developed social media policies, the NLRB’s stance permits employers to monitor and analyze employees’ social media use and does not clarify when an employer can act on social media information
