Supporting adaptiveness of cyber-physical processes through action-based formalisms

Cyber Physical Processes (CPPs) refer to a new generation of business processes enacted in many application environments (e.g., emergency management, smart manufacturing, etc.), in which the presence of Internet-of-Things devices and embedded ICT systems (e.g., smartphones, sensors, actuators) strongly influences the coordination of the real-world entities (e.g., humans, robots, etc.) inhabitating such environments. A Process Management System (PMS) employed for executing CPPs is required to automatically adapt its running processes to anomalous situations and exogenous events by minimising any human intervention. In this paper, we tackle this issue by introducing an approach and an adaptive Cognitive PMS, called SmartPM, which combines process execution monitoring, unanticipated exception detection and automated resolution strategies leveraging on three well-established action-based formalisms developed for reasoning about actions in Artificial Intelligence (AI), including the situation calculus, IndiGolog and automated planning. Interestingly, the use of SmartPM does not require any expertise of the internal working of the AI tools involved in the system

Enacting Accountability in IS Research after the Sociomaterial Turn(ing)

Sociomateriality represents an emergent philosophical stance that instantiates an ontological turn towards relationality and materiality in information systems (IS) research. As an emergent perspective or way of seeing, sociomateriality has significant implications for researchers and the practices they employ. If we accept that the ontological, epistemological, and methodological assumptions we enact in our research shape the realities we perceive and create, questions around researchers’ accountability for the realities they produce need to be addressed. The sociomaterial turn(ing) in IS challenges our deeply held assumptions about what constitutes reality. What are these challenges, and how are they being addressed in sociomaterial research? And what implications for accountability in IS research more generally does a turn towards relationality and materiality hold? The objectives of this editorial are: (1) to sensitize IS researchers, irrespective of their ontological and epistemological persuasions, to the field’s turn(ing) toward relationality and materiality; (2) to provide insight into the practices of data generation, analysis, and presentation through which this turn(ing) is being enacted in sociomaterial theorizing; and (3) to contemplate the implications of this turn(ing) for the accountability of IS research more generally

Losing Touch:An embodiment perspective on coordination in robotic surgery

Because new technologies allow new performances, mediations, representations, and information flows, they are often associated with changes in how coordination is achieved. Current coordination research emphasizes its situated and emergent nature, but seldom accounts for the role of embodied action. Building on a 25-month field study of the da Vinci robot, an endoscopic system for minimally invasive surgery, we bring to the fore the role of the body in how coordination was reconfigured in response to a change in technological mediation. Using the robot, surgeons experienced both an augmentation and a reduction of what they can do with their bodies in terms of haptic, visual, and auditory perception and manipulative dexterity. These bodily augmentations and reductions affected joint task performance and led to coordinative adaptations (e.g., spatial relocating, redistributing tasks, accommodating novel perceptual dependencies, and mounting novel responses) that, over time, resulted in reconfiguration of roles, including expanded occupational knowledge, emergence of new specializations, and shifts in status and boundaries. By emphasizing the importance of the body in coordination, this paper suggests that an embodiment perspective is important for explaining how and why coordination evolves following the introduction of a new technology

A planning approach to the automated synthesis of template-based process models

The design-time specification of flexible processes can be time-consuming and error-prone, due to the high number of tasks involved and their context-dependent nature. Such processes frequently suffer from potential interference among their constituents, since resources are usually shared by the process participants and it is difficult to foresee all the potential tasks interactions in advance. Concurrent tasks may not be independent from each other (e.g., they could operate on the same data at the same time), resulting in incorrect outcomes. To tackle these issues, we propose an approach for the automated synthesis of a library of template-based process models that achieve goals in dynamic and partially specified environments. The approach is based on a declarative problem definition and partial-order planning algorithms for template generation. The resulting templates guarantee sound concurrency in the execution of their activities and are reusable in a variety of partially specified contextual environments. As running example, a disaster response scenario is given. The approach is backed by a formal model and has been tested in experiment

Technological roadmap on AI planning and scheduling

At the beginning of the new century, Information Technologies had become basic and indispensable constituents of the production and preparation processes for all kinds of goods and services and with that are largely influencing both the working and private life of nearly every citizen. This development will continue and even further grow with the continually increasing use of the Internet in production, business, science, education, and everyday societal and private undertaking. Recent years have shown, however, that a dramatic enhancement of software capabilities is required, when aiming to continuously provide advanced and competitive products and services in all these fast developing sectors. It includes the development of intelligent systems – systems that are more autonomous, flexible, and robust than today’s conventional software. Intelligent Planning and Scheduling is a key enabling technology for intelligent systems. It has been developed and matured over the last three decades and has successfully been employed for a variety of applications in commerce, industry, education, medicine, public transport, defense, and government. This document reviews the state-of-the-art in key application and technical areas of Intelligent Planning and Scheduling. It identifies the most important research, development, and technology transfer efforts required in the coming 3 to 10 years and shows the way forward to meet these challenges in the short-, medium- and longer-term future. The roadmap has been developed under the regime of PLANET – the European Network of Excellence in AI Planning. This network, established by the European Commission in 1998, is the co-ordinating framework for research, development, and technology transfer in the field of Intelligent Planning and Scheduling in Europe. A large number of people have contributed to this document including the members of PLANET non- European international experts, and a number of independent expert peer reviewers. All of them are acknowledged in a separate section of this document. Intelligent Planning and Scheduling is a far-reaching technology. Accepting the challenges and progressing along the directions pointed out in this roadmap will enable a new generation of intelligent application systems in a wide variety of industrial, commercial, public, and private sectors

How Does Robotic Surgery Influence Communication, Leadership, and Team Outcomes? A Multimethod Examination.

The practice of delivering surgical care has evolved to be less invasive to the patients undergoing surgery. Minimally-invasive surgery can be practiced through traditional laparoscopic methods as well as with robotic technology that displaces the surgeon from the operating table. Robotic surgery has been cited to be safer and more effective than traditional laparoscopic surgery; however, little research has endeavored to investigate the role of surgical modality upon aspects of teamwork. This dissertation contributes to the human factors and teamwork literature by evaluating how surgical modality may influence communication, shared leadership, and team outcomes. Multiple methods were employed to study robotic and non-robotic (i.e., open and laparoscopic) surgical teams. Teams were evaluated through video analysis of surgical procedures as well as questionnaire methods. The results of this research revealed very few modality-specific differences which may represent the adaptive nature of teams and individuals. Robotic surgical team members did not perceive a statistically significant difference in communication quality which may indicate that the impact of the closed console design may be relatively benign in this regard. While there were no statistically significant differences between the degree to which robotic and non-robotic teams shared or perceived shared leadership, there were interesting role and leadership behavior type differences. For instance, the assists conducted significantly more leadership in robotic surgery than in laparoscopic surgery. In the video data, sharing leadership to a greater extent led to shorter operative durations. In the survey data, higher perceptions of communication quality and communication behavior significantly predicted higher perceptions of team effectiveness, indicating a strong positive relationship between perceived communication and perceived effectiveness. As robotic surgical systems and practices continue to inevitably advance in the coming years, developers should be keenly aware of the interdependencies between all aspects of the sociotechnical system including the providers and recipients of care, the environment and organization, and the tools and technologies

Bodies in place : enactive cognition as development of ecological norms

Les partisans de l’approche énactive soutiennent que la cognition se constitue à travers l’histoire des différentes formes d'interaction (biologique, sensorimotrice, intercorporelle, linguistique, etc.) entre un vivant et son environnement. Ces interactions ne sont pas aléatoires, mais des activités obéissant à certaines normes que les énactivistes appellent sense-making. La cognition est, de ce point de vue, une forme de sense-making. Malgré les avantages indéniables que confère une telle perspective pour étudier la cognition, la présente thèse développe un point de vue critique par rapport à l’approche énactive et soutient qu'il est nécessaire d'approfondir notre compréhension de la dimension écologique du sense-making. Le but principal de la thèse est en conséquence de montrer que l'environnement joue un rôle encore plus important que l’approche énactive ne lui attribue habituellement. En m'engageant de manière critique dans le répertoire conceptuel de la cognition énactive, de la phénoménologie et des approches écologiques de la cognition, l’objectif de cette thèse consiste à poser les bases conceptuelles d'une approche énactive-écologique de la cognition. Pour ce faire, la thèse s’attèle à mettre de l’avant trois idées principales. La première consiste à redéfinir le concept du sense-making : contrairement à la conception qui s’est traditionnellement imposée dans le mouvement énactif, nous allons démontrer qu’il s’agit d’un phénomène de développement (et non de création) de normes. La rencontre du corps et du monde est toujours ancrée dans un champ normatif prédéfini, de sorte que nous devons réévaluer le rôle que joue l'environnement dans les processus de sense-making. En effet, si les agents se retrouvent toujours-déjà plongés dans un champ normatif (et non dans un environnement purement causal et physique), il faut alors reconnaître que l'environnement joue un rôle actif dans la constitution et l'auto-transformation des normes de sense-making. La deuxième idée poursuit dans cette veine et porte sur cette nouvelle conception de l'environnement, qui est ici défini comme un champ normatif actif, incarnant une tension entre le passé habituel du système agent-environnement et les contingences incessantes des événements du monde qui poussent le système vers leur auto-transformation et développement. La troisième idée principale de cette thèse consiste en une description holistique du champ d'action des agents (un lieu énactif) et des normes édictées (enacted) par des processus de sense-making sur le terrain (normes de lieu). Une esquisse générale du lieu énactif montre que les activités de sense-making sont liées à des processus écologiques qui enchevêtrent de multiples agents et localités matérielles dans un réseau écologique local. Ces réseaux écologiques forment une unité systémique et résiliente qui se déploie dans le temps avec les habitants du lieu, et fonctionne comme un champ normatif qui contraint et motive l'auto-transformation de chaque système agent-environnementSupporters of autonomist enactivism or the enactive approach claim that cognition is a phenomenon constituted by the historical development of different forms of interaction (biological, sensorimotor, intercorporeal, and linguistic) between living bodies and their environments. For autonomist enactivists, the nature of these interactions is not entirely predetermined by general laws of causation but by norms enacted in the historical path of the agent-environment system, and thanks to processes of sense-making. Cognition is, from the enactivist standpoint, a form of sense-making. While there are multiple advantages in holding such perspective to study mind and cognition, this thesis develops a critical point of view and argues that it is necessary to deepen our understanding of the ecological dimension of sense-making. Specifically, the thesis aims to show that the environment plays a more critical role than autonomist enactivism usually attributes to it. By drawing on and critically engaging with the conceptual repertoire of enactive cognition, phenomenology, and ecological approaches to cognition, my objective is to set the conceptual foundations for an enactive-ecological approach to cognition. For this task, I propose three interrelated ideas. The first redefines sense-making as a phenomenon of norm development. The most common descriptions of sense-making involve the emergence of meaning from raw physical matter thanks to the activity of living organisms. As norm development, by contrast, sense-making refers to a constant enactment and re-enactment of norms of interaction from other pregiven norms, previously enacted in the past of the agent-environment system. I argue that the encounter of the body and the world is permanently embedded in a pregiven normative field and never in an abstract void where raw physical interactions occur. From this standpoint, we need, however, to re-evaluate the role that the environment plays in sense-making processes. If agents find themselves immersed in normative fields and not in raw physical landscapes, then the environment has a more active role for the constitution and self-transformation of sense-making norms than autonomist enactivists have acknowledged. In this vein, the second main idea of this thesis concerns the environment as an active normative field that incarnates a tension between the habitual past of the agent-environment system and the ongoing contingencies of worldly events that push the system to their self-transformation and development. The third main idea of this thesis consists of a holistic description of the field of action of agents (enactive place) and the norms enacted by processes of sense-making in the field (place-norms). A general sketch of enactive place shows that sense-making is tied to processes that entangle multiple agents and material localities into a local ecological web. An enactive place constitutes a systemic and resilient unity that unfolds in time altogether with its inhabitants, working as a normative field that constrains and motivates the self-transformation of each agent-environment system. Bodies are therefore part of wider unities of historical development: places

Simulating activities: Relating motives, deliberation, and attentive coordination

Activities are located behaviors, taking time, conceived as socially meaningful, and usually involving interaction with tools and the environment. In modeling human cognition as a form of problem solving (goal-directed search and operator sequencing), cognitive science researchers have not adequately studied “off-task” activities (e.g., waiting), non-intellectual motives (e.g., hunger), sustaining a goal state (e.g., playful interaction), and coupled perceptual-motor dynamics (e.g., following someone). These aspects of human behavior have been considered in bits and pieces in past research, identified as scripts, human factors, behavior settings, ensemble, flow experience, and situated action. More broadly, activity theory provides a comprehensive framework relating motives, goals, and operations. This paper ties these ideas together, using examples from work life in a Canadian High Arctic research station. The emphasis is on simulating human behavior as it naturally occurs, such that “working” is understood as an aspect of living. The result is a synthesis of previously unrelated analytic perspectives and a broader appreciation of the nature of human cognition. Simulating activities in this comprehensive way is useful for understanding work practice, promoting learning, and designing better tools, including human-robot systems

Robotic Knitting

As a reaction to typically dead-end debates on future human and robot collaboration that tend to be either dismissive or overly welcoming towards »cobot« technologies, this book provides a technofeminist intervention. Pat Treusch not only shows how both the fields of technofeminism and robotics can engage in a practical exchange through knitting, but also contributes a tangible example of coboting dynamics. Robotic Knitting re-negotiates the boundaries between formalisation and embodiment, craft and high-tech as well as useful and dysfunctional machines. It re-crafts the nature of collaboration between human and robot. This finally entails an alternative mode of relating - a mode that enables an account of careful coboting
