Abstract

Purpose

Six years ago, Bonneau et al. (2012) proposed a framework to compare authentication schemes to the ubiquitous text password. Even though their work did not reveal an alternative outperforming the text password on every criterion, the framework can support decision makers in finding suitable solutions for specific authentication contexts. The purpose of this paper is to extend and update the database, thereby discussing benefits, limitations and suggestions for continuing the development of the framework.

Design/methodology/approach

This paper revisits the rating process and describes the application of an extended version of the original framework to an additional 40 authentication schemes identified in a literature review. All schemes were rated in terms of 25 objective features assigned to the three main criteria: usability, deployability and security.

Findings

The rating process and results are presented along with a discussion of the benefits and pitfalls of the rating process.

Research limitations/implications

While the extended framework, in general, proves suitable for rating and comparing authentication schemes, ambiguities in the rating could be solved by providing clearer definitions and cut-off values. Further, the extension of the framework with subjective user perceptions that sometimes differ from objective ratings could be beneficial.

Originality/value

The results of the rating are made publicly available in an authentication choice support system named ACCESS to support decision makers and researchers and to foster the further extension of the knowledge base and future development of the extended rating framework.

Abstract

This study explores how thinking infrastructures can orchestrate collective sensemaking in unstable and socially contested environments, such as large-scale humanitarian crises. In particular, drawing from recent interest in the role of artifacts and infrastructures in sensemaking processes, the study examines the evaluative underpinnings of prospective sensemaking as groups attempt to develop novel understandings about a desired but ambiguous set of future conditions. To explore these theoretical concerns, a detailed case study of the unfolding challenges of managing a large-scale humanitarian crisis response was conducted. This study offers two contributions. Firstly, it develops a theorization of the process through which performance evaluation systems can serve as thinking infrastructures in the collaborative development of new understandings in unstable environments. Secondly, this study sheds light on the practices that support prospective sensemaking through specific features of thinking infrastructures, and unpacks how prospective and retrospective forms of sensemaking may interact in such processes.

Abstract

This volume brings together empirical and conceptual papers that investigate the challenges of organizing creativity in the innovation journey in and across different empirical contexts. Seen as the basis for innovating new products, processes or services, organizing creativity is studied as intentional efforts that occur in teams, organizations, and fields. What creativity is, how it is defined, negotiated and recognized is hereby co-constructed with different audiences and in different economic and societal spheres. The papers in this volume extend our understanding of these contextualized social dynamics of organizing creativity in four directions. The first direction sheds light on the temporal dynamics of organizing creativity in artistic fields. The second direction compares creative processes in arts and science, thereby examining tensions and uncertainties in the creative process unfolding in two distinctive contexts of creativity. The third direction examines identity struggles of creative agents in organizations with clashing roles, professional norms, and ambiguities in creativity assessment. The fourth and final direction unravels the communicative journey of ideas from pitching to feedback, revealing how ideas are challenged, enriched, and acquire meaning in communicative interaction. Overall, the papers in this volume contribute to a situated view of creative processes in innovation which goes beyond questions of idea generation to account for dynamics of idea development, judgment, and dissemination which involve identity struggles, evaluation, and communication – processes which are at the heart of organizing for innovation.

Abstract

Political correctness, also known as “PC,” has generated much discussion on both the Right and the Left. The greatest debate comes from college campuses. Political correctness derives from the principle that ethnic diversity, i.e., multiculturalism, can and should be preserved and protected. Ironically, the term originated in the Marxist era, when it was used to enforce conformity in the advancement of a particular Marxist view. The term became obsolete until it was revived in the 1980s (D'Souza, 1991).

Abstract

Purpose

Global navigation satellite systems (GNSS) were designed to determine the exact location of objects on land, water and air for military purposes. With the opening of the satellite signal for civilian use, the technology created business opportunities for various applications. Today, satellite positioning technology is used by transporters, carriers, motorists, surveyors, builders, foresters, etc. through a wide array of devices like mobile phones or multimedia devices with built-in receiver modules.

Design/methodology/approach

This paper provides the results of a recently held foresight exercise on the future development of Russia’s GLONASS system.

Findings

The foresight exercise suggested a number niche markets where the GLONASS technology could be of great use, like monitoring of buildings and construction sides or the monitoring of shipments. In addition, in the case of Russia, large-scale government-driven investment programs will be key drivers for GLONASS’ growth perspectives.

Originality/value

The paper provides a comprehensive picture of the development of GNSS for civilian use until 2020.

Abstract

Purpose

The purpose of this paper is to analyze the role of industrial self-supply in the transition process from centralized energy generation based on fossil fuels and nuclear power to decentralized supply based on renewable energies in the Bavarian electricity system.

Design/methodology/approach

To quantify effects on system and price stability, a model of the Bavarian electricity grid is created and used to simulate electricity system behavior during a 1-year period for scenarios that are characterized by parameter variations in industrial self-supply, nuclear power capacity, renewable power generation and the capacity of electricity imports.

Findings

The simulations show that industrial self-supply can reduce instances of maximum grid utilization by 23 per cent and, based on the merit-order effect, decrease electricity market prices by 1.90 and 5.03 €/MWh in the scenarios with and without nuclear power, respectively; these values represent 5.7 and 15.0 per cent of average market prices from 2014.

Research limitations/implications

The analysis shows that industrial self-supply can contribute to transforming the electricity system in a secure, sustainable and affordable manner. However, merit-order-based price effects have a limitation concerning the future applicability of results as quantified effects may not be permanent when the electricity system adapts.

Originality/value

This paper connects industrial self-supply and the merit-order effect within a nodal energy model. It provides insights into the relevant interdependencies and reciprocal effects by means of a simulation.

Abstract

Purpose

Much research has been conducted on technology acceptance (TA), which is mainly about the acceptance by one user. As more than one person should be involved in business-to-business TA decision-making, it is suggested that different processes for making a consensus among different stakeholders should be considered. The purpose of this study is to demonstrate a model for essential activities and characteristics of advocators for accelerating the stakeholders’ consensus in the technology acceptance (SCTA).

Design/methodology/approach

The conceptual model of this research is presented using a thematic analysis of the interviews with the relevant experts and existing literature. Furthermore, the structural equation model was applied for analyzing empirically how advocators’ characteristics and activities affect consensus. In total, 248 respondents completed the questionnaires. Experts’ opinions, Krippendorff’s alpha index, Cronbach’s alpha coefficient and goodness of fit indices were applied to verify the reliability of the results.

Findings

Results show that “being leader” and “being influential” are two main characteristics for the advocators’ team that significantly affect SCTA. Reducing perceived “risk” for each stakeholder, developing a “common understanding” among them and demonstrating “resource readiness” are also the main tasks of advocators leading to SCTA.

Originality/value

The role of advocators in SCTA has been neglected. The main contribution of this study is identifying the required advocators’ activities and characteristics for achieving SCTA.

Abstract

Purpose

Burgeoning challenges of climate change and poverty alleviation across many parts of the world have enforced the policy makers and researchers to develop an alternate system for performance assessment of an individual, a country, and a corporate. The purpose of this paper is to analyze the sustainability strategies of three leading states in the Indian leather industry – Tamil Nadu (TN), West Bengal (WB) and Uttar Pradesh (UP) – to gain insights into their efforts and progress in generating economic, social, and environmental values.

Design/methodology/approach

This study used case study approach for investigative analysis, and triangulation method – interviews and field visits, for data verification. The study examines the various sustainability strategies by applying economic value creation (evaluation of growth in total turnover, evaluation of the growth in profitability, evaluation of leverage), social value creation (evaluation of the growth in wages, evaluation of the growth in employee welfare expenses), and environmental value creation (conservation in raw material consumption, conservation in energy consumption, evaluation of waste management practices).

Findings

The findings reveal that the three states differ significantly from each other both in terms of efforts made and progress achieved during the period of study, 1998-2013. UP seems to be making the most consistent progress in achieving economic value, while WB shows the most progress in creating social value, and TN leads the pack in terms of creating environmental value. Thus, the three leading states in the Indian leather industry have been allowing trade-offs to get competitive advantage over others.

Research limitations/implications

The opaqueness with which the Indian leather Industry conducts social and environmental practices clearly limits the sources of accurate and reliable data, and the ability of researchers to precisely identify the problems and suggest solutions.

Practical implications

The opaqueness with which the Indian leather Industry conducts social and environmental practices clearly impacts the policy makers, practitioners, and researchers to continue such initiatives and improve the lives of people in India for whom continuing this profession is a big challenge and a hurdle to accomplish their livelihood.

Originality/value

The paper gives a theoretical explanation of the sustainability in the leather industry with respect to its strategies in terms of economic value, social value, and environmental value.
