Dynamics of Affordances and Implications for Design

Affordance is an important concept in HCI. There are various interpretations of affordances but it has been difficult to use this concept for design purposes. Often the treatment of affordances in the current HCI literature has been as a one-to-one relationship between a user and an artefact. According to our views, affordance is a dynamic, always emerging relationship between a human and his environment. We believe that the social and cultural contexts within which an artefact is situated affect the way in which the artefact is used. Using a Structuration Theory approach, we argue that affordances need also be treated at a much broader level, encompassing social and cultural aspects. We suggest that affordances should be seen at three levels: single user, organizational (or work group) and societal. Focusing on the organizational level affordances, we provide details of several important factors that affect the emergence of affordances

Ontology modeling for generation of clinical pathways

Purpose: Increasing costs of health care, fuelled by demand for high quality, cost-effective healthcare has drove hospitals to streamline their patient care delivery systems. One such systematic approach is the adaptation of Clinical Pathways (CP) as a tool to increase the quality of healthcare delivery. However, most organizations still rely on are paper-based pathway guidelines or specifications, which have limitations in process management and as a result can influence patient safety outcomes. In this paper, we present a method for generating clinical pathways based on organizational semiotics by capturing knowledge from syntactic, semantic and pragmatic to social level. Design/methodology/approach: The proposed modeling approach to generation of CPs adopts organizational semiotics and enables the generation of semantically rich representation of CP knowledge. Semantic Analysis Method (SAM) is applied to explicitly represent the semantics of the concepts, their relationships and patterns of behavior in terms of an ontology chart. Norm Analysis Method (NAM) is adopted to identify and formally specify patterns of behavior and rules that govern the actions identified on the ontology chart. Information collected during semantic and norm analysis is integrated to guide the generation of CPs using best practice represented in BPMN thus enabling the automation of CP. Findings: This research confirms the necessity of taking into consideration social aspects in designing information systems and automating CP. The complexity of healthcare processes can be best tackled by analyzing stakeholders, which we treat as social agents, their goals and patterns of action within the agent network. Originality/value: The current modeling methods describe CPs from a structural aspect comprising activities, properties and interrelationships. However, these methods lack a mechanism to describe possible patterns of human behavior and the conditions under which the behavior will occur. To overcome this weakness, a semiotic approach to generation of clinical pathway is introduced. The CP generated from SAM together with norms will enrich the knowledge representation of the domain through ontology modeling, which allows the recognition of human responsibilities and obligations and more importantly, the ultimate power of decision making in exceptional circumstances

The Gentle Art of Retroduction: Critical Realism, Cultural Political Economy and Critical Grounded Theory

This article, first, proposes critical grounded theory (CGT) as a way to develop systematically an array of methods and theoretical propositions into a coherent critical methodology for organization studies (and beyond). Second, it demonstrates CGT’s usefulness through a case study of competing recovery projects from the Icelandic financial crisis. CGT is developed in engagement with the emerging paradigm of cultural political economy (CPE) and its preferred method of critical discourse analysis (CDA). CPE analyses the evolution of ‘economic imaginaries’ in both their structural/material and semiotic/discursive dimensions. This requires a critical realist, multi-dimensional research strategy which emphasizes ethnographic methods and substantial theoretical and historical work. The proposed methodology of CGT enables a retroductive research process that combines deductive theoretical deskwork with inductive fieldwork enabled by grounded theory tools to analyse organizational process, stability and change

Sensemaking on the Pragmatic Web: A Hypermedia Discourse Perspective

The complexity of the dilemmas we face on an organizational, societal and global scale forces us into sensemaking activity. We need tools for expressing and contesting perspectives flexible enough for real time use in meetings, structured enough to help manage longer term memory, and powerful enough to filter the complexity of extended deliberation and debate on an organizational or global scale. This has been the motivation for a programme of basic and applied action research into Hypermedia Discourse, which draws on research in hypertext, information visualization, argumentation, modelling, and meeting facilitation. This paper proposes that this strand of work shares a key principle behind the Pragmatic Web concept, namely, the need to take seriously diverse perspectives and the processes of meaning negotiation. Moreover, it is argued that the hypermedia discourse tools described instantiate this principle in practical tools which permit end-user control over modelling approaches in the absence of consensus

Notes on narrative, cognition, and cultural evolution

Drawing on non-Darwinian cultural-evolutionary approaches, the paper develops a broad, non-representational perspective on narrative, necessary to account for the narrative “ubiquity” hypothesis. It considers narrativity as a feature of intelligent behaviour and as a formative principle of symbolic representation (“narrative proclivity”). The narrative representation retains a relationship with the “primary” pre-symbolic narrativity of the basic orientational-interpretive (semiotic) behaviour affected by perceptually salient objects and “fits” in natural environments. The paper distinguishes between implicit narrativity (as the basic form of perceptual-cognitive mapping) of intelligent behaviour or non-narrative media, and the “narrative” as a symbolic representation. Human perceptual-attentional routines are enhanced by symbolic representations: due to its attention-monitoring and information-gathering function, narrative serves as a cognitive-exploratory tool facilitating cultural dynamics. The rise of new media and mass communication on the Web has thrown the ability of narrative to shape the public sphere through the ongoing process of negotiated sensemaking and interpretation in a particularly sharp relief

Knowledge management and history

Capitalisation of the history of a technology, a technique or a concept within an industrial company is relevant to historians. However it largely exceeds the historical problems from a Knowledge Management point of view. In this context, it can be the subject of specific approaches especially Knowledge Engineering. However, it faces two types of difficulties: - The techniques in History have few modelling tools, and are even rather reticent with the use of such tools. - Knowledge Engineering doesn't often address historical knowledge modelling, for tracing knowledge evolution. It is however possible to develop robust and validated methods, tools and techniques which take into account these two approaches, which, if they function in synergy, appear rich and fertile.History, MASK, Knowledge management, Knowledge engineering, History of techniques

SRI analysis and asset management : independent or convergent ? : A field study on the French market

This article analyzes how the actual and expected future activities of French Socially Responsible Investment (SRI) analysts may reveal a convergence process between SRI decisions and traditional financial investment decisions, that is a form of "mainstreaming" of SRI processes, by asking the SRI analysts themselves how their work has evolved and how they perceive their positioning in the asset management sector. We present the results of a field survey on the composition and activities of French SRI analysts' teams of large institutional investors and asset managers in France in 2009. We show that the convergence towards the mainstream financial analysts seems to be clearly engaged. However, the SRI domain is still emerging and remains very fragmented leading to a wide heterogeneity of practices and positioning in the respective organizations. This is interpreted as a clear sign of a transition phase.Field survey ; French Asset Management industry ; Mainstreaming ; Socially Responsible Investments (SRI)
