Supervisory Control for Modal Specifications of Services

International audienceIn the service oriented architecture framework, a modal specification, as defined by Larsen in \cite{Lar89}, formalises how a service should interact with its environment. More precisely, a modal specification determines the events that the server may or must allow at each stage in an interactive session. Therefore, techniques to enforce a modal specification on a system would be useful for practical applications. In this paper, we investigate the adaptation of the supervisory control theory of Ramadge and Wonham to enforce a modal specification (with final states marking the ends of the sessions) on a system modelled by a finite LTS. We prove that there exists at most one most permissive solution to this control problem. We also prove that this solution is regular and we present an algorithm for the effective computation of the corresponding controlle

Designing Institutional Infrastructure for E-Science

A new generation of information and communication infrastructures, including advanced Internet computing and Grid technologies, promises more direct and shared access to more widely distributed computing resources than was previously possible. Scientific and technological collaboration, consequently, is more and more dependent upon access to, and sharing of digital research data. Thus, the U.S. NSF Directorate committed in 2005 to a major research funding initiative, “Cyberinfrastructure Vision for 21st Century Discovery”. These investments are aimed at enhancement of computer and network technologies, and the training of researchers. Animated by much the same view, the UK e-Science Core Programme has preceded the NSF effort in funding development of an array of open standard middleware platforms, intended to support Grid enabled science and engineering research. This proceeds from the sceptical view that engineering breakthroughs alone will not be enough to achieve the outcomes envisaged. Success in realizing the potential of e-Science—through the collaborative activities supported by the "cyberinfrastructure," if it is to be achieved, will be the result of a nexus of interrelated social, legal, and technical transformations.e-science, cyberinfrastructure, information sharing, research

TOWARDS INSTITUTIONAL INFRASTRUCTURES FOR E-SCIENCE: The Scope of the Challenge

The three-fold purpose of this Report to the Joint Information Systems Committee (JISC) of the Research Councils (UK) is to: • articulate the nature and significance of the non-technological issues that will bear on the practical effectiveness of the hardware and software infrastructures that are being created to enable collaborations in e- Science; • characterise succinctly the fundamental sources of the organisational and institutional challenges that need to be addressed in regard to defining terms, rights and responsibilities of the collaborating parties, and to illustrate these by reference to the limited experience gained to date in regard to intellectual property, liability, privacy, and security and competition policy issues affecting scientific research organisations; and • propose approaches for arriving at institutional mechanisms whose establishment would generate workable, specific arrangements facilitating collaboration in e-Science; and, that also might serve to meet similar needs in other spheres such as e- Learning, e-Government, e-Commerce, e-Healthcare. In carrying out these tasks, the report examines developments in enhanced computer-mediated telecommunication networks and digital information technologies, and recent advances in technologies of collaboration. It considers the economic and legal aspects of scientific collaboration, with attention to interactions between formal contracting and 'private ordering' arrangements that rest upon research community norms. It offers definitions of e-Science, virtual laboratories, collaboratories, and develops a taxonomy of collaborative e-Science activities which is implemented to classify British e-Science pilot projects and contrast these with US collaboratory projects funded during the 1990s. The approach to facilitating inter-organizational participation in collaborative projects rests upon the development of a modular structure of contractual clauses that permit flexibility and experience-based learning.

‘All we’ve ever known is Covid’: A follow-up study with newly qualified nurses who worked as student nurses during the pandemic

© 2022 The Authors. Journal of Clinical Nursing published by John Wiley & Sons Ltd. This is an open access article under the terms of the Creative Commons Attribution License https://creativecommons.org/licenses/by/4.0/Aims and objectives: To explore the experiences of nursing students in England who had worked through the first wave and transitioned to qualification in the ongoing pandemic. Background: Experiences of health professionals and student nurses during the pandemic are now well documented, but transition of students to qualification is less well understood. In Summer 2020 we interviewed 16 student nurses who had worked as health care assistants on paid extended placements as part of the Covid-19 response in the East of England, finding surprisingly positive experiences, including perceived heightened preparedness for qualification. A year later we re-interviewed 12 participants from the original study to hear about transitioning to qualification during the ongoing pandemic. This study provides novel insights into their experiences. Design: A qualitative study design was used. Methods: 12 newly qualified nurses who had participated in the original study took part in qualitative, online interviews where they shared their experiences of working and transitioning to qualification during the ongoing pandemic since we spoke to them a year earlier. The data was analysed using thematic analysis. COREQ guidelines were used in developing and reporting this study. Results: 3 themes were identified. Constant change: in the clinical environment and arising out of the transition to newly qualified nurse, mental health and well-being, and reflecting on the past to learn for the future. Conclusions: Participants experienced a unique transition to qualification. The perceived heightened preparedness for qualification that participants who had worked as students during the first wave of the pandemic had become a reality, ameliorating some of the known effects of transition. However, increased expectations and added responsibilities in extremely busy, fluctuating clinical environments with minimal support add weight to calls for mandatory preceptorship programmes. While heightened resilience was evident, provision of ongoing mental health and well-being support is strongly recommended. Relevance to Clinical Practice: We need a partnership approach with nurse educators and practice colleagues which ensures preparation for qualified practice is appropriate. If we do not effectively prepare students for qualified nurse posts, patient care will almost certainly be compromised.Peer reviewe

Prosecuting Dark Net Drug Marketplace Operators Under the Federal Crack House Statute

Over 70,000 Americans died as the result of a drug overdose in 2017, a record year following a record year. Amidst this crisis, the popularity of drug marketplaces on what has been called the “dark net” has exploded. Illicit substances are sold freely on such marketplaces, and the anonymity these marketplaces provide has proved troublesome for law enforcement. Law enforcement has responded by taking down several of these marketplaces and prosecuting their creators, such as Ross Ulbricht of the former Silk Road. Prosecutors have typically leveled conspiracy charges against the operators of these marketplaces—in Ulbricht’s case, alleging a single drug conspiracy comprising Ulbricht and the thousands of vendors on the Silk Road. This Note argues that the conspiracy to distribute narcotics charge is a poor conceptual fit for the behavior of operators of typical dark net drug marketplaces, and that the federal “crack house” statute provides a better charge. Though charging these operators under the crack house statute would be a novel approach, justice is best served when the crime accurately describes the behavior, as the crack house statute does in proscribing what dark net drug marketplace operators like Ulbricht do
