In pursuit of rigour and accountability in participatory design

The field of Participatory Design (PD) has greatly diversified and we see a broad spectrum of approaches and methodologies emerging. However, to foster its role in designing future interactive technologies, a discussion about accountability and rigour across this spectrum is needed. Rejecting the traditional, positivistic framework, we take inspiration from related fields such as Design Research and Action Research to develop interpretations of these concepts that are rooted in PD׳s own belief system. We argue that unlike in other fields, accountability and rigour are nuanced concepts that are delivered through debate, critique and reflection. A key prerequisite for having such debates is the availability of a language that allows designers, researchers and practitioners to construct solid arguments about the appropriateness of their stances, choices and judgements. To this end, we propose a “tool-to-think-with” that provides such a language by guiding designers, researchers and practitioners through a process of systematic reflection and critical analysis. The tool proposes four lenses to critically reflect on the nature of a PD effort: epistemology, values, stakeholders and outcomes. In a subsequent step, the coherence between the revealed features is analysed and shows whether they pull the project in the same direction or work against each other. Regardless of the flavour of PD, we argue that this coherence of features indicates the level of internal rigour of PD work and that the process of reflection and analysis provides the language to argue for it. We envision our tool to be useful at all stages of PD work: in the planning phase, as part of a reflective practice during the work, and as a means to construct knowledge and advance the field after the fact. We ground our theoretical discussions in a specific PD experience, the ECHOES project, to motivate the tool and to illustrate its workings

What was the programme theory of New Labour’s health system reforms?

To examine whether the Health System Reforms delivered the promise of being a coherent and mutually supporting reform programme; to identify the underlying programme theory of the reform programme; to reflect on whether lessons have been learned. \ud \ud Documentary analysis mapping the implicit and explicit programme theories about how the reforms intended to achieve its goals and outcomes. Semi-structured interviews with policy-makers to further understand the programme theory. \ud \ud The Health System Reforms assumed a ‘one size fits all’ approach to policy implementation with little recognition that some contexts can be more receptive than others. There was evidence of some policy evolution and rebalancing between the reform streams as policy-makers became aware of some perverse incentives and unforeseen consequences. Later elements aimed to restore balance to the system. \ud \ud The Health System Reforms do not appear to comprise a coherent and mutually supportive set of levers and incentives. They appear unbalanced with the centre of gravity favouring suppliers over commissioners. However, recent reform changes have sought to redress this imbalance to some extent, suggesting that lessons have been learned and policies have been adapted over time

Attitudes towards shared decision making in mental health: A qualitative synthesis

Purpose: Shared decision making (SDM) prioritises joint deliberation between practitioner and service user, and a respect for service-users’ experiential knowledge, values and preferences. The purpose of this paper is to review the existing literature pertaining to key stakeholders’ attitudes towards SDM in mental health. It examines whether perceived barriers and facilitators differ by group (e.g. service user, psychiatrist, nurse and social worker) and includes views of what facilitates and hinders the process for service users and practitioners. Design/methodology/approach: This review adopts the principles of a qualitative research synthesis. A key word search of research published between 1990 and 2016 was undertaken. Qualitative, quantitative and mixed methods studies were included. Findings: In total, 43 papers were included and several themes identified for service user and practitioner perspectives. Both practitioners and service users see SDM as an ethical imperative, and both groups highlight the need to be flexible in implementing SDM, suggesting it is context dependent. A range of challenges and barriers are presented by both practitioners and service users reflecting complex contextual and cultural features within which interactions in mental health take place. There were qualitative differences in what service users and practitioners describe as preventing or enabling SDM. The differences highlighted point towards different challenges and priorities in SDM for service users and practitioners. Originality/value: The presentation of nuanced views and attitudes that practitioners and service users hold represent an important and under reported area and offer insight into the reasons for the gap between idealised policy and actual practice of SDM in mental health settings

The Feasibility of Dynamically Granted Permissions: Aligning Mobile Privacy with User Preferences

Current smartphone operating systems regulate application permissions by prompting users on an ask-on-first-use basis. Prior research has shown that this method is ineffective because it fails to account for context: the circumstances under which an application first requests access to data may be vastly different than the circumstances under which it subsequently requests access. We performed a longitudinal 131-person field study to analyze the contextuality behind user privacy decisions to regulate access to sensitive resources. We built a classifier to make privacy decisions on the user's behalf by detecting when context has changed and, when necessary, inferring privacy preferences based on the user's past decisions and behavior. Our goal is to automatically grant appropriate resource requests without further user intervention, deny inappropriate requests, and only prompt the user when the system is uncertain of the user's preferences. We show that our approach can accurately predict users' privacy decisions 96.8% of the time, which is a four-fold reduction in error rate compared to current systems.Comment: 17 pages, 4 figure

Off the record?: Arrestee concerns about the manipulation, modification, and misrepresentation of police body-worn camera footage

Police body-worn cameras (BWC) have become the latest technological device introduced to policing on a wave of panacean promises. Recent research has reported the perspectives of police officers, police management, and the general public, but there have been no studies examining the views of police arrestees. Remedying this significant omission, this article presents findings generated from interviews with 907 individuals shortly after their arrest. Overall, we report a strong in principle support for police body-worn cameras amongst this cohort, particularly if the cameras can be operated impartially. The findings are organised into a trilogy of prominent and interrelated concerns voiced by the police detainees, namely the potential for the manipulation, modification, and misrepresentation of events captured by police body-worn cameras. The findings are discussed in a broader context of the “new visibility” of police encounters and contribute much needed findings to understand the culturally specific ways in which different publics experience and respond to visual surveillance

Implications for Adoption

In this paper we explore the motivations for, and practicalities of, incorporating ‘implications for adoption’ into HCI research practice. Implications for adoption are speculations which may be used in research projects to scrutinize and explore the implications and requirements associated with a technology’s potential adoption in the future. There is a rich tradition within the HCI community of implementing, demonstrating, and testing new interactions or technologies by building prototypes. User-centered design methods help us to develop prototypes to and move toward designs that are validated, efficient, and rewarding to use. However, these studies rarely shift their temporal focus to consider, in any significant detail, what it would mean for a technology to exist beyond its prototypical implementation, in other words how these prototypes might ultimately be adopted. Given the CHI community’s increasing interest in technology-related human and social effects, the lack of attention paid to adoption represents a significant and relevant gap in current practices. It is this gap that the paper addresses and in doing so offers three contributions: (1) exploring and unpacking different notions of adoption from varying disciplinary perspectives; (2) discussing why considering adoption is relevant and useful, specifically in HCI research; (3) discussing methods for addressing this need, specifically design fiction, and understanding how utilizing these methods may provide researchers with means to better understand the myriad of nuanced, situated, and technologically-mediated relationships that innovative designs facilitate

The Influence of Invasive Species on Fishers’ Satisfactions

Invasives species are prevalent and widespread in North America. Outdoor recreational activities, such as fishing, introduce a point in which humans may interact with invasive species and have to adapt their own behaviors. Bigheaded carp in the Missouri River below Gavin’s Point Dam are a group of invasive fish species that were thought to be negatively relating to recreational fishers’ satisfactions. Using a content analysis and an importance-grid, we conclude that invasive species do not strongly relate to recreational paddlefish fishers’ satisfactions. Paddlefish fishers represent a small sub-set of recreational fishers in Nebraska and South Dakota. The content analysis revealed that only a very small subset of fishers’ are reporting concerns related to bighead carp and an even smaller subset relate to negative sentiments about bigheaded carp. The importance-grid analysis revealed that at both the day-level and the season-level, paddlefish fishers satisfactions are strongly related to harvest of a paddlefish and that factors relating to bigheaded carp and other invasive species is unimportant rather than detrimental. There is no difference in how bigheaded carp factors are classified on the importance grid between method of take, with is contrary to the hypothesis that archery fishers may have stronger positive influence of bigheaded carp towards fishing satisfactions given the additional targets they create. It is likely that bigheaded carp are becoming normalized to the point of leniency in fishers and thus they are not identifying them categorically as invasive species and are shifting their expectations in regard to dealing with their presence. Future studies related to the influence of invasive species on fishers’ satisfactions could consider a non-limited recreational fishery and could focus more on the archery method of take, which has anecdotally been more keen to target species like bigheaded carp.

The Pragmatic Turn in Explainable Artificial Intelligence (XAI)

In this paper I argue that the search for explainable models and interpretable decisions in AI must be reformulated in terms of the broader project of offering a pragmatic and naturalistic account of understanding in AI. Intuitively, the purpose of providing an explanation of a model or a decision is to make it understandable to its stakeholders. But without a previous grasp of what it means to say that an agent understands a model or a decision, the explanatory strategies will lack a well-defined goal. Aside from providing a clearer objective for XAI, focusing on understanding also allows us to relax the factivity condition on explanation, which is impossible to fulfill in many machine learning models, and to focus instead on the pragmatic conditions that determine the best fit between a model and the methods and devices deployed to understand it. After an examination of the different types of understanding discussed in the philosophical and psychological literature, I conclude that interpretative or approximation models not only provide the best way to achieve the objectual understanding of a machine learning model, but are also a necessary condition to achieve post hoc interpretability. This conclusion is partly based on the shortcomings of the purely functionalist approach to post hoc interpretability that seems to be predominant in most recent literature

Colin Mochrie vs. Jesus H. Christ: Messages About Masculinities and Fame in Online Video Conversations

With the availability of relatively easy-to-use tools for online video creation and distribution, people are increasingly producing videos not just for artistic expression, but also as a form of communication. This article examines two types of online video conversations, one within a specific online subculture, and one a series of responses to one particularly wellknown video. Videos lend themselves to the expression of ambiguity, contradictory meanings, taboo topics, and emotions. Within these two video conversations, topics include discussions of masculinity, identity, and fame.published or submitted for publicationis peer reviewe
