Generating repudiable, memorizable and privacy preserving security questions using the Propp Theory of Narrative

 Security questions are often based on personal information that is limited in variety, available in the public record and very difficult to change if compromised. A personalized folktale shared only by the communicating parties provides memorizable basis for individualized security questions that can be readily replaced in the event of a security breach. We utilize the Propp theory of narrative to provide a basis of abstraction for story generation systems. We develop a proof-of-concept system based on placeholder replacement to demonstrate the generation of repudiate and memorizable questions and answers suitable for online security questions. A 3-component protocol is presented that demonstrates the use of this process to derive a shared secret key through privacy amplification. This combination of story generation and communication security provides the basis for improvements in current security question practice.

Consensual commitment: a grounded theory of the meso-level influence of organizational design on leadership and decision-making

This research examined the relationship between organizational design and leadership in decision-making teams. It used a grounded theory-based qualitative research design. The validity of the research was enhanced by data triangulation, wherein quantitative psychometric data augmented the qualitative data that are traditionally used. The research was based upon two organizations within the substantive setting of the knowledge industry. The higher order category of consensual commitment explained effective decision-making. At the meso-level of leadership modeling, organizational design influenced both leadership style and decision-making. Specifically, an organizational design that generated lateral job roles and a relational leadership orientation was found to enhance consensual commitment, and provided a level of assurance against dysfunctional team dynamics. © 2009 Elsevier Inc.

A meta-analysis of the effects of measuring theory of planned behaviour constructs on behaviour within prospective studies

Measurement reactivity effects, such as the mere measurement effect, have been proposed as a reason for behavioural changes in a number of theory of planned behaviour intervention studies. However, it is unclear whether such changes are the result of the mere measurement effect or of other artefacts of intervention study design. The aim of this study is to determine the size and direction of changes in health behaviours from baseline to follow-up in prospective studies using the theory of planned behaviour. Electronic databases were searched for the theory of planned behaviour studies which measured health behaviours at two or more time points. Change in behaviour was calculated for all studies. Sixty-six studies were included. Mean effect sizes across all studies were small and negative (d = -.03). Effect size was moderated by behaviour, behaviour type and follow-up length. Subgroup analyses showed significant decreases in socially undesirable behaviour (d = -.28), binge drinking (d = -.17), risk driving (d = -.20), sugar snack consumption (d = -.43) and sun-protective behaviour (d = -.18). Measurement of intention at baseline resulted in significant decreases in undesirable behaviour. Changes in undesirable behaviours reported in other studies may be the result of the mere measurement effect.

Imago veritas falsa: for a (post-)Schmittian decisionist theory of law, legal reasoning, and judging

For decades, while approaching the ‘normativism/pragmatism’ divide and discussing the legitimacy of (and opportunity for) the judge to act as a ‘social engineer’, socio-legal scholars have tried to ascertain whether the jurist should also consider the impact of his/her activity on society at large, and if so, why and to what extent. The present contribution understands instead the law in terms of a structurally incomplete image (imago veritas falsa) which always needs the decisive intervention of the legal interpreter to exercise its performative instances. In particular, by adopting an unconventional theoretico-philosophical approach that transcends the classic boundaries of foundationalist metaphysics as expressed by the dichotomy of Western logic, this paper argues for the necessity of a tertium comparationis capable of explaining that the real essence of law, legal reasoning, and judging is neither that of normativism, nor of pragmatism, but rather of (post-)Schmittian decisionism.

A general theory of tourism consumption systems: a conceptual framework and an empirical exploration

A tourism consumption system (TCS) is defined as the setof related travel thoughts, decisions, and behaviors by a discretionarytraveler prior to, during, and following a trip. Thecentral proposition of a theory of TCS is that the thoughts,decisions, and behaviors regarding one activity influence thethoughts, decisions, and behaviors for a number of other activities.Using exit interview travel data and quick clusteringanalysis, this article empirically examines seven basic TCSpropositions pertaining to decisions made once the destinationhas been selected. The findings support and extend thebasic propositions specifically indicating clear patterns inthe behaviors of visitors to Prince Edward Island, Canada.The authors conclude by recommending that this approach isuseful for tourism marketers and practitioners in general.Suggestions are provided for analyzing TCS to increase theeffectiveness of tourism marketing strategies.

Toward a receiver-based theory of knowledge sharing

Managers and researchers alike have sought new ways to address the challenges of sharing dispersed knowledge in modern business environments. Careful consideration by sharers of receivers' knowledge needs and behaviours may improve the effectiveness of organisational knowledge sharing. This research examines how sharers react to their perceptions of receivers' knowledge needs and behaviours when making choices relating to sharing knowledge. The focus of this article is to propose and empirically explore a theoretical framework for a study of the role of the receiver in knowledge sharing - receiver-based theory. Data collected from two case studies highlight a key role played by perceived receiver knowledge needs and behaviours in shaping sharer choices when explicit knowledge is shared. A set of receiver influences on knowledge sharing is provided that highlights key receiver and sharer issues. The paper concludes that companies should develop better ways to connect potential sharers with receivers' real knowledge needs. Further, the findings suggest that sharing on a need-to-know basis hinders change in organisational power structures, and prevents the integration of isolated pockets of knowledge that may yield new value. © 2008, IGI Global.

A Jamesonian theory of theological practice: a critical response to the work of Roland Boer

In a conjuncture marked by the “resurgence of religion,” the problem of historical materialism’s relation to religious ideologies has acquired a new urgency. The work of Roland Boer, recently awarded the Deutscher Prize for his magnum opus on Marxism and Theology poses this question from a surprising perspective. While his main claim is that religious influences in Marxist theory represent a sort of theological unconscious in historical materialism, at the same time Boer also advances an original Marxist interpretation of the Abrahamic religions, especially Christianity. This line of research, which extends from his dissertation on Jameson and Jeroboam through to his most recent work on The Sacred Economy, proposes that theology is a reflective representation of the social totality. In this article, I criticise Boer’s valorisation of theology as a practical discourse that is post-ideological but non-theoretical, and conclude by indicating an alternative.

A demandeur-centric theory of regime design in transnational commercial law

Recent scholarship on international agreement design has almost exclusively focused on the public international law area. The literature on regime design in the area of international private law lacks a solid theoretical foundation. Academic writing on public international law's state-centric approach is only amenable to crude transplantation and poses several puzzles in the international private law context. Resolving these puzzles is important because of the proliferation of transnational commercial agreements in areas that were traditionally the province of domestic law. This paper attempts to provide a starting point to address the theoretical vacuum. Part I argues that functionalist, liberal, and realist theories cannot fully explain transnational commercial law agreement design. Part II puts forth a demandeur-centric approach with the aid of examples that span the spectrum from hard law to soft law. Part III concludes that agreement design in transnational commercial law is premised on demandeur preferences and relative power.

Towards a theory of landscape iconoclasm

The destruction of Indigenous rock art sites in the Pilbara district in Western Australia has become a natural sight within the mining landscape of the area. Whilst much of the destruction is explained as acts of vandalism and as a result of the industrial activities that are propelling the Australian economy, I claim that a new theory of iconoclasm is needed to explain fully this disastrous example of heritage conservation. Henceforth, in order to explain the destruction of the Murujuga/Burrup Peninsula petroglyphs, the largest archaeological site in the world, this paper develops the theory of landscape iconoclasm. This theory states that the destruction of Indigenous landscapes can be compared to the destruction of religious images, by analysing the inherent symbolic functions of iconoclasm, together with those of heritage, the better to elucidate the state of affairs in the Murujuga/Burrup Peninsula. Furthermore, by drawing from Aboriginal mythology and art-historical and anthropological theories, the theory of landscape iconoclasm is able to explain the destruction of archaeological sites within a framework that falls outside prevalent discourses of heritage.
