Groups usually carry out science and decision-making activities involving geographic information. However, current mapping and related geospatial technologies are not group-friendly, and attempts to extend (or reinvent) technologies for group use have been largely ad hoc. Elsewhere, we have developed a comprehensive conceptual approach to geocollaboration that provides a framework for both studying collaborative work with geospatial information (and technologies) and the development of new technologies designed to support group work. We are applying that approach to a range of prototype systems that support same- and different-place as well as same- and different-time group activities.Our focus in this paper is on same-time, same-place group work environments that enable that work through use of large-screen displays supporting natural, human-system dialogue and multi-user interaction. Two environments are described and compared. Both make use of hand gestures as a mechanism for specifying display locations. One adopts a combined wall map/white board metaphor while the other adopts a drafting table metaphor. We focus on crisis management as a typical use case.

Abstract Background Several technological innovations have been introduced in healthcare over the years, and their implementation proved crucial in addressing challenges of modern health. Healthcare workers have frequently been called upon to become familiar with technological innovations that pervade every aspect of their profession, changing their working schedule, habits, and daily actions. Purpose An in-depth analysis of the paths towards the acceptance and use of technology may facilitate the crafting and adoption of specific personnel policies taking into consideration definite levers, which appear to be different in relation to the age of nurses. Approach The strength of this study is the application of UTAUT model to analyse the acceptance of innovations by nurses in technology-intensive healthcare contexts. Multidimensional Item Response Theory is applied to identify the main dimensions characterizing the UTAUT model. Paths are tested through two stage regression models and validated using a SEM covariance analysis. Results The age is a moderator for the social influence: social influence, or peer opinion, matters more for young nurse. Conclusion The use of MIRT to identify the most important items for each construct of UTAUT model and an in-depth path analysis helps to identify which factors should be considered a leverage to foster nurses’ acceptance and intention to use new technologies (o technology-intensive devices). Practical implications Young nurses may benefit from the structuring of shifts with the most passionate colleagues (thus exploiting the social influence), the participation in ad hoc training courses (thus exploiting the facilitating conditions), while other nurses could benefit from policies that rely on the stressing of the perception of their expectations or the downsizing of their expectancy of the effort in using new technologies.

Sample Set

The emergence of ubiquitous computing (UbiComp) environments has increased the risk of undesired access to individuals’ physical space or their information, anytime and anywhere, raising potentially serious privacy concerns. Individuals lack awareness and control of the vulnerabilities in everyday contexts and need support and care in regulating disclosures to their physical and digital selves. Existing GUI-based solutions, however, often feel physically interruptive, socially disruptive, time-consuming and cumbersome. To address such challenges, we investigate the user interaction experience and discuss the need for more tangible and embodied interactions for effective and seamless natural privacy management in everyday UbiComp settings. We propose the Privacy Care interaction framework, which is rooted in the literature of privacy management and tangible computing. Keeping users at the center, Awareness and Control are established as the core parts of our framework. This is supported with three interrelated interaction tenets: Direct, Ready-to-Hand, and Contextual . Direct refers to intuitiveness through metaphor usage. Ready-to-Hand supports granularity, non-intrusiveness, and ad hoc management, through periphery-to-center style attention transitions. Contextual supports customization through modularity and configurability. Together, they aim to provide experience of an embodied privacy care with varied interactions that are calming and yet actively empowering. The framework provides designers of such care with a basis to refer to, to generate effective tangible tools for privacy management in everyday settings. Through five semi-structured focus groups, we explore the privacy challenges faced by a sample set of 15 older adults (aged 60+) across their cyber-physical-social spaces. The results show conformity to our framework, demonstrating the relevance of the facets of the framework to the design of privacy management tools in everyday UbiComp contexts.

Functional Software

The vehicle-embedded system also known as the electronic control unit (ECU) has transformed the humble motorcar, making it more efficient, environmentally friendly, and safer, but has led to a system which is highly dependent on software. As new technologies and features are included with each new vehicle model, the increased reliance on software will no doubt continue. It is an undeniable fact that all software contains bugs, errors, and potential vulnerabilities, which when discovered must be addressed in a timely manner, primarily through patching and updates, to preserve vehicle and occupant safety and integrity. However, current automotive software updating practices are ad hoc at best and often follow the same inefficient fix mechanisms associated with a physical component failure of return or recall. Increasing vehicle connectivity heralds the potential for over the air (OtA) software updates, but rigid ECU hardware design does not often facilitate or enable OtA updating. To address the associated issues regarding automotive ECU-based software updates, a new approach in how automotive software is deployed to the ECU is required. This paper presents how lightweight virtualisation technologies known as containers can promote efficient automotive ECU software updates. ECU functional software can be deployed to a container built from an associated image. Container images promote efficiency in download size and times through layer sharing, similar to ECU difference or delta flashing. Through containers, connectivity and OtA future software updates can be completed without inconveniences to the consumer or incurring expense to the manufacturer.

This article describes the process of design, validation, and implementation (N = 609) of a questionnaire drawn up ad hoc to assess the digital competence of compulsory education students (ages 11 to 13) in the area of communication. The test measures students’ knowledge, skills, and attitudes in the six competences that make up the area of communication, as established in the Framework for the Development and Knowledge of Digital Competence in Europe (DigComp): interacting through new technologies, sharing of information and content, online citizen participation, collaboration through digital technologies, netiquette, and digital identity management. The purposes of the study are to design and validate an instrument to assess compulsory education students’ digital competences in the area of communication based on their knowledge, skills, and attitudes and to analyse such instrument’s psychometric characteristics with special emphasis on its reliability and validity. The method used consisted of the implementation of various psychometric validation techniques and the analysis of the results based on statistical descriptions. Items show adequate discrimination and difficulty indices. Validity was guaranteed through expert judgement and factorial analysis of the test. The conclusion stresses the pressing need for education centres to provide students with adequate educational-communicative training.

Ubiquitous environments such as Vehicular Ad Hoc Networks need applications that allow them to integrate data and services to build knowledge that can be used to make decisions and to improve standards of living and user safety, among others. We have designed a collaborative virtual environment that covers the needs of integration of knowledge from different vehicles to endow the final user with the necessary information. This environment has been carried out following a model-driven approach that generates a groupware application for improving collaborative work and access to services. The implemented tool facilitates the development and implementation of collaborative frameworks in VANETs, where every vehicle acts as a node.

The chapter aims at drawing attention to the possibilities that geospatial technologies can bring to science mapping. In what follows, the chapter briefly distinguishes the notion of mapping between the Geospatial Information Science (GIScience) and Librarianship and Information Science (LIS). Afterwards, an overview about recent initiatives and research work relative to (geospatial) mapping of science is presented. Based on these examples, opportunities and challenges of applying geospatial technology to science mapping are discussed. Finally, based on relevant while evolving geospatial technologies, next steps for increasing up the influence of geospatial technology in science mapping are pointed out.

Small Work

In both corporate and academic organizations, collaborative work is frequently accomplished and managed in small work groups. These can take either the form of formal work groups or ad hoc task groups. The formal work group has relatively permanent membership, ongoing tasks, and routinized reporting relationships within the organization. Over time, skills and information of group members become more group-specific and norms more implicit. There is less communication on how to work together and more on the work itself (Finholt, Sproull, and Kiesler, 1990). Some types of work are, however, best performed in ad hoc or quickly formed task groups. According to Finholt, Sproull, and Kiesler (1990), such groups are convened for a particular purpose, consist of members who otherwise would not work together, and disband after completing their assigned task. These task groups permit an organization to respond rapidly to changes in the environment and to non-routine problems by calling on expertise regardless of where it resides in the organization. In higher education, a particular form of ad hoc task group is familiar to many instructors—the student project team. Such teams are commonly formed to allow students to tackle projects that are too big to handle individually, to allow students to teach and learn from one another, and to create opportunities for practicing the intricate dynamics of collaborative work. Given the benefits claimed for ad hoc task groups, it is presumed to be a good thing for students to gain hands-on experience in their function.
