Holistic Security Requirements Engineering for Socio-Technical Systems
… institutions, as security breaches in the systems they depend have repeatedly resulted in losses of billions per year, and this cost is on the rise. A primary reason for these breaches is the “socio-technical” nature of today’s systems that consist of an amal- gam of social and human …

Entity recognition for multi-modal socio-technical systems
… as a method for extracting information about socio-technical systems from unstructured, natural language text data. This process is limited by the set of entity classes considered in many current ER solutions. In this thesis, we report on the development of an ER classifier that supports a …

Participating and designing around algorithmic socio-technical systems
… users’ behavior around opaque algorithmic systems and create new designs that communicate opaque algorithmic processes to users and provide them with a more informed, satisfying, and engaging interaction. In doing so, I add new angles to the old idea of understanding the interaction between …

Creative networks : socio-technical systems for loosely bound cooperation
This thesis introduces a programming environment entitled Share that is designed to support and encourage loosely bound cooperation between individuals within communities of practice through the sharing of code. Loosely bound cooperation refers to the opportunity members of communities have to …

STS: a Security Requirements Engineering methodology for socio-technical Systems
Today’s software systems are situated within larger socio-technical systems, wherein they interact — by exchanging data and delegating tasks — with other technical components, humans, and organisations. The components (actors) of a socio-technical system are autonomous and loosely controllable. …

Change or be changed: understanding resilience in socio-technical systems
… through the maintenance and redesign of existing systems, as well as the design and integration of new systems. Each of these systems has stakeholders at different levels and across domains, from those governing societies, to technical experts working on well-defined tasks. These stakeholders …

Enhancing methods for modeling and estimation of complex socio-technical systems
… rigor of simulation models of complex dynamic systems in social sciences and to enhance the use of quantitative data in the estimation of model structure and parameters. The data available to social scientists developing models of complex systems are often severely limited and suffer from …

Designing Socio-Technical Systems to Illuminate Possibilities for a Vulnerable Population
… We explored the potential role that socio-technical systems and technology designers can play in assisting the survivors to build on their existing assets towards their vision of "dignified reintegration". The research involves three fieldwork and a remote study, each one leveraging …

Production Pressure in Complex Socio-Technical Systems: Analysis, Measurement, and Prediction
… organizational goals - efficiency and safety, in sociotechnical systems (STSs). This research mainly focuses on production pressure (PrP) which is considered as one of the main negative outcomes of overprioritizing the efficiency aspect of STSs. This work seeks to introduce novel methodologies for …

Analysis of transformations to socio-technical systems using agent based modeling and simulation
Transformations to socio-technical systems may be enacted at fairly low levels, i.e., through changes in technology, processes, information and workers, to obtain a change in system level performance. This thesis provides a conceptual framework and a simulation platform to a priori computationally …

Risk and Socio-technical Systems: A study of the Taiwanese Campus Accident Reporting System
… of risk governance within the functioning of a socio-technical system in a hierarchical organization. I explore the actual problems of operators of the Campus Security Report System and the solutions they deploy as different groups of people. The thesis examines the governance of risk-related …

A phenomenographic study of the ability to address complex socio-technical systems via variation theory
… fail when addressing the inherent complexity of socio-technical systems because they lack the ability to address the complexity of socio-technical systems. Teaching undergraduate engineering students how to address complex socio-technical systems, has been an educational endeavor at different …

A socio-technical systems analysis of change processes in the design of flagship interplanetary missions
In the engineering of complex systems, changes to flight hardware or software after initial release can have large impacts on project implementation. Even a comparatively small change on an assembly or subsystem can cascade into a significant amount of rework if it propagates through the system. …

Heterogeneous Decision-Making in Socio-Technical Systems Methodologies for Efficiency Measurement and Decision Analysis with Mixed Data
… advances the performance evaluation of complex socio-technical systems (STSs) by integrating systems theory with methodological innovations in Data Envelopment Analysis (DEA). Traditional DEA models, while robust in assessing relative efficiency across multiple inputs and outputs, implicitly …

Who, When, How (Not) to Imitate? The Role of Imitation in Collective Intelligence, and Its Implications on the Design of Socio-Technical Systems
… can provide essential guidance for the design of socio-technical systems.

Systems thinking applied to automation and workplace safety
… presents the results of a study to compare Systems-Theoretic Process Analysis (STPA), a hazard analysis methodology based on a new model of accident causation called Systems-Theoretic Accident Model and Processes (STAMP), with the traditional assessments recommended by industry standards for …

A new approach to risk analysis with a focus on organizational risk factors
Preventing accidents in complex socio-technical systems requires an approach to risk management that continuously monitors risk and identifies potential areas of concern before they lead to hazards, and constrains hazards before they lead to accidents. This research introduces the concept of …

Privacy in the small
… laws has profoundly influenced organizations' socio-technical structures, mandating compliance with stringent personal data processing standards. These laws compel entities to critically understand their socio-technical systems, encompassing the complex interplay between legal, managerial, and …

Security in Practice: Examining the Collaborative Management of Sensitive Information in Childcare Centers and Physicians' Offices
… in secure (or insecure) ways in part of a larger socio-technical system. Socio-technical systems are comprised of people, technology, relationships, and interactions that work together to create safe praxis. Because information systems are not just technical, but also social, the scope of privacy …
