Purpose – The aim of the research is to realize a better form of personal identification number (PIN) authentication for a mobile phone without lowering usability and acceptability. Design/methodology/approach – The authors’ approach is to extend the input operation of PIN authentication by allowing more than one number at a time using a multi-touch-enabled screen. The authors also introduced substitution keys to be able to type any combination of a PIN value and an input pattern by multi-touch typing. Findings – The authors conducted a user evaluation study using a Web-based prototype system. The results of the study indicate that PIN input time, input errors and secret memorability of the proposed scheme were no worse than those of conventional PIN authentication. The theoretical security level of the proposed scheme is almost three and a half times than that of the conventional scheme. Originality/value – The paper introduced a multi-touch-allowed secret input operation into a PIN authentication. Though the introduction affected not only an input operation but also a PIN input interface and secret information, it makes possible to realize a better security level without a drastic change of a user interface and taking a longer input time.

Purpose Although many interventional approaches have been proposed to address the apparent gap between novices and experts for literature review (LR) search tasks, there have been very few approaches proposed for manuscript preparation (MP) related tasks. The purpose of this paper is to describe a task and an incumbent technique for shortlisting important and unique papers from the reading list (RL) of researchers, meant for citation in a manuscript. Design/methodology/approach A user evaluation study was conducted on the prototype system which was built for supporting the shortlisting papers (SP) task along with two other LR search tasks. A total of 119 researchers who had experience in authoring research papers participated in this study. An online questionnaire was provided to the participants for evaluating the task. Both quantitative and qualitative analyses were performed on the collected evaluation data. Findings Graduate research students prefer this task more than research and academic staff. The evaluation measures relevance, usefulness and certainty were identified as predictors for the output quality measure “good list”. The shortlisting feature and information cues were the preferred aspects while limited data set and rote steps in the study were ascertained as critical aspects from the qualitative feedback of the participants. Originality/value Findings point out that researchers are clearly interested in this novel task of SP from the final RL prepared during LR. This has implications for digital library, academic databases and reference management software where this task can be included to benefit researchers at the manuscript preparatory stage of the research lifecycle.

Purpose Systems to support literature review (LR) and manuscript preparation tend to focus on only one or two of the tasks involved. The purpose of this paper is to describe an intervention framework that redesigns a particular set of tasks, allowing for interconnectivity between the tasks and providing appropriate user interface display features for each task in a prototype system. Design/methodology/approach A user evaluation study was conducted on the prototype system. The system supports the three tasks: building a reading list (RL) of research papers, finding similar papers based on a set of papers and shortlisting papers from the final RL for inclusion in manuscript based on article type. A total of 119 researchers who had experience in authoring research papers, participated in the evaluation study. They had to select one of the provided 43 topics and execute the tasks offered by the system. Three questionnaires were provided for evaluating the tasks and system. Both quantitative and qualitative analyses were performed on the collected evaluation data. Findings Task redesign aspects had a positive impact in user evaluation for the second task of finding similar papers while improvement was found to be required for the first and third tasks. The tasks interconnectivity features seed basket and RL were helpful for the participants in conveniently searching for papers within the system. Two of the four proposed informational display features, namely, information cue labels and shared co-relations were the most preferred features of the system. Student user group found the task recommendations and the overall system to be more useful and effective than the staff group. Originality/value This study validates the importance of interconnected task design and novel informational display features in accentuating task-based recommendations for LR and manuscript preparatory tasks. The potential for improvement in recommendations was shown through the task redesign exercise where new requirements for the tasks were identified. The resultant prototype system helps in bridging the gap between novices and experts in terms of LR skills.

Purpose – The purpose of this paper is to improve users’ search results relevancy by manipulating their explicit feedback. Design/methodology/approach – CoRRe – an explicit feedback model integrating three popular feedback, namely, Comment-Rating-Referral is proposed in this study. The model is further enhanced using case-based reasoning in retrieving the top-5 results. A search engine prototype was developed using Text REtrieval Conference as the document collection, and results were evaluated at three levels (i.e. top-5, 10 and 15). A user evaluation involving 28 students was administered, focussing on 20 queries. Findings – Both Mean Average Precision and Normalized Discounted Cumulative Gain results indicate CoRRe to have the highest retrieval precisions at all the three levels compared to the other feedback models. Furthermore, independent t-tests showed the precision differences to be significant. Rating was found to be the most popular technique among the participants, producing the best precision compared to referral and comments. Research limitations/implications – The findings suggest that search retrieval relevance can be significantly improved when users’ explicit feedback are integrated, therefore web-based systems should find ways to manipulate users’ feedback to provide better recommendations or search results to the users. Originality/value – The study is novel in the sense that users’ comment, rating and referral were taken into consideration to improve their overall search experience.

Purpose – The purpose of this paper is to investigate the feasibility of creating a declarative user interface language suitable for rapid prototyping of mobile and Web apps. Moreover, this paper presents a new framework for creating responsive user interfaces using JavaScript. Design/methodology/approach – Very little existing research has been done in JavaScript-specific declarative user interface (UI) languages for mobile Web apps. This paper introduces a new framework, along with several case studies that create modern responsive designs programmatically. Findings – The fully implemented prototype verifies the feasibility of a JavaScript-based declarative user interface library. This paper demonstrates that existing solutions are unwieldy and cumbersome to dynamically create and adjust nodes within a visual syntax of program code. Originality/value – This paper presents the Guix.js platform, a declarative UI library for rapid development of Web-based mobile interfaces in JavaScript.

Purpose – The purpose of this paper is to argue that the time is ripe to establish a powerful tradition in Experimental International Business (IB). Probably due to what the Arjen van Witteloostuijn refers to as the external validity myth, experimental laboratory designs are underutilized in IB, which implies that the internal validity miracle of randomized experimentation goes largely unnoticed in this domain of the broader management discipline. Design/methodology/approach – In the following pages, the author explains why the author believes this implies a missed opportunity, providing arguments and examples along the way. Findings – Although an Experimental Management tradition has never really gained momentum, to the author, the lab experimental design has a very bright future in IB (and management at large). To facilitate the development of an Experimental IB tradition, initiating web-based tools would be highly instrumental. This will not only boost further progress in IB research, but will also increase the effectiveness and playfulness of IB teaching. Originality/value – Given the high potential of an Experimental IB, the Cross-Cultural and Strategic Management journal will offer a platform for such exciting and intriguing laboratory work, cumulatively contributing to the establishment of an Experimental IB tradition.

Purpose This study examines the websites of central government ministries, prefectures and municipalities to obtain a comprehensive bird’s-eye view of how they are preparing for natural disasters in the context of the novel coronavirus (COVID-19) outbreak. Design/methodology/approach This study examines the websites of central government ministries, prefectures and municipalities in Japan to survey the actual status of information dissemination on “evacuation and sheltering” in the context of COVID-19. Findings This study found that the central government issued many notices, notifications and administrative communications to prefectures, cities with public health centers and special wards, which were mainly related to opening, securing and operating evacuation centers and improving the environment. It was found that most prefectures disseminated information on both survival and living evacuation and did so from June onward, when the flood season was approaching. Among the municipalities, there were differences in information dissemination tendencies by prefecture, and it became clear that smaller municipalities were especially incapable of fully disseminating information via the Web. Research limitations/implications The data from the prefectures and municipalities surveyed in this study were collected from websites and do not necessarily represent the actual response to disaster-related evacuation in the context of COVID-19 in those areas. To clarify this evacuation, more detailed surveys are needed. Originality/value This study is unique because no research has been conducted on the response of Japanese administrative agencies to disaster-related evacuation in the context of COVID-19; the actual situation was analyzed in this study by examining central government ministries, prefectures and municipalities as administrative agencies and comparing their responses.

Purpose – The purpose of this paper is to devote the optimal substitution of slip rings through an inductive power transfer system for field winding supply of generators or motors with a wound rotor. By a rotational pot-core transformer approach, the rotor-side energizing of the excitation windings can be provided isolated and free of wear. Design/methodology/approach – For design purpose, an analytical model of the inductive link and the compensation network elements is shown. Based on a pot-core transformer approach, possible types of compensation networks regarding motor-specific constraints were carried out and compared among themselves by parameter studies. The analytical parts of the model were subsequently validated with measured data of an appropriate core and accompanying FEM calculations. On the basis of an experimental prototype system, the approach has been tested both stationary and transient. Findings – The publication exemplifies how a brushless excitation system for generators and motors can be inexpensively designed and implemented. Originality/value – This paper systematically presents a comprehensive analytical approach for brushless excitation systems as well as a prototypical system. Compensation network elements regarding motor-specific constraints were carried out and compared among themselves by parameter studies.

PurposeThe purpose of this paper is to investigate consumer’s acceptance toward product innovation in the agri-food sector, uncovering consumers’ characteristics able to encourage food innovation acceptance.Design/methodology/approachThe analysis was carried out by administering a web-based structured questionnaire to a convenient sample of 443 Italian consumers. The study relies on consumers’ willingness to pay (WTP) to assess consumers’ acceptance toward the innovative product, while the Food-Related Lifestyle scale was applied to perform a cluster analysis aiming at detecting the attitude of consumers toward innovations in a traditional food.FindingsThe study findings showed a clear openness of consumers toward product innovation. Indeed, consumers’ WTP for the innovative product was far higher than the traditional one. Further, two out of three consumers’ groups detected (i.e. pro-innovation and rational adopters) exhibit a broad correlation between the innovative product attributes and consumers’ psychographics characteristics, revealing the existence of a large number of potential consumers.Originality/valueThe contribution of the paper to the current literature is twofold. First, it focused on an emerging topic for the agri-food sector (i.e. product innovation) whereby research works are still scarce. Second, product innovation was addressed toward a traditional food that is mostly reluctant to innovation due to consumers’ resistance and skepticism.

PurposeThe Saint Mary’s College of California (SMC) library plays an integral role in supporting one of the goals in the College’s Strategic Plan: “Raise the Academic Profile and Distinction”. This case study aims to assess the effectiveness of PlumX as a tool to showcase the academic profile and distinction of SMC. The library recognizes the importance of capturing impact of non-traditional creativity and engagement in addition to just traditional impact metrics of research. Design/methodology/approachThis paper describes the collaborative effort of the College and the College’s library to identify faculty scholarship, creativity and engagement and collect data demonstrating the impact of the works. Traditional metrics, like citation counts, do not do SMC faculty justice because faculty scholarship comes beyond just books and articles. To more fully document the real intellectual corpus the College, the library is working with a new system, PlumX, to collect web-based information about both traditionally and non-traditionally published work. FindingsThe collection of metrics across five categories (citations, usage, social media, mentions and captures), and the flexibility of displaying on screen or downloading for use in other analytic reports made possible through PlumX proved to be a start toward demonstrating the academic distinction of College’s unique faculty. SMC will continue to partner with PlumX to assess and improve its usability and effectiveness. Originality/valueThis paper outlines how altmetrics can be used to measure and share impact of faculty research at a liberal arts, teaching-focused college in ways reflective of the unique intellectual contributions.
