Abstract

Purpose

This paper describes the development of the veraPDF validator. The objective of veraPDF is to build an industry supported, open source validator for all parts and conformance levels of the PDF/A specification for archival PDF documents. The project is led by the Open Preservation Foundation and the PDF Association and is funded by the EU PREFORMA project.

Design/methodology/approach

veraPDF is designed to meet the needs of the digital preservation community and the PDF industry alike. The technology is subject to the review of and acceptance by the PDF Association’s PDF Validation Technical Working Group, including many participants of the relevant ISO working groups. Cultural heritage institutions are collecting ever-increasing volumes of digital information, which they have a mandate to preserve for the long term. However, in many cases, they need to ensure their content has been produced to the specifications of a standard file format, as well as any acceptance criteria stated in their institutional policy.

Findings

With increasing knowledge and experience of processes and policies, cultural heritage institutions are influencing the production and development of digital preservation software. The product development funded by the PREFORMA project shows how such cooperation can benefit the community as a whole.

Originality/value

This paper describes the value of an open source approach to developing a PDF/A validator for cultural heritage organisations.

Abstract

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.

Abstract

Purpose

With the rapid increase in internet use, most people tend to purchase books through online stores. Several such stores also provide book recommendations for buyer convenience, and both collaborative and content-based filtering approaches have been widely used for building these recommendation systems. However, both approaches have significant limitations, including cold start and data sparsity. To overcome these limitations, this study aims to investigate whether user satisfaction can be predicted based on easily accessible book descriptions.

Design/methodology/approach

The authors collected a large-scale Kindle Books data set containing book descriptions and ratings, and calculated whether a specific book will receive a high rating. For this purpose, several feature representation methods (bag-of-words, term frequency–inverse document frequency [TF-IDF] and Word2vec) and machine learning classifiers (logistic regression, random forest, naive Bayes and support vector machine) were used.

Findings

The used classifiers show substantial accuracy in predicting reader satisfaction. Among them, the random forest classifier combined with the TF-IDF feature representation method exhibited the highest accuracy at 96.09%.

Originality/value

This study revealed that user satisfaction can be predicted based on book descriptions and shed light on the limitations of existing recommendation systems. Further, both practical and theoretical implications have been discussed.

Abstract

There has been long‐term interest in the processes that affect human‐computer interaction, particularly those causing stress. Computer related stress has previously been correlated to general stress (Cohen, Kamarack, and Mermelstein 1983) and to somatic complaints (Derogatis et al. 1974). A negative correlation between perceived stress and academic performance has also been documented (Hudiburg and Jones 1991). This study compares computer related stress levels in three business student populations (239 students): juniors who have not begun their major course work, seniors who are MIS majors, and graduate MBA students. Using standard analysis of variance, we found that MIS students experienced a significantly higher number of stressors than the other two groups and a greater average severity of stress than the premajors. Human‐computer interaction is suspected to be more stressful for MIS students than other business students because their use of computers is greater and their grades are more heavily weighted toward computer work. This study further considers the various personality types/learning styles of these students and investigates how they might be accommodated to minimize anxiety. The Myers‐Briggs Type Indicator (MBTI) test and a computer assignment preference test were administered to the 239 students. Recommendations for different learner types, in terms of environment variables and computer assignment characteristics, were made.

Abstract

Purpose

Digital transformation has been changing the economic environment of enterprises in recent years. To remain competitive, they rely on an extensible software architecture, flexible workflow execution, and automated decision management. The concepts of service-oriented architectures (SOA), business process management (BPM), and business rules management (BRM) provide an adequate, yet isolated means of addressing many of these requirements. The paper aims to discuss these issues.

Design/methodology/approach

This study adapts from established research frameworks to structure the current state of research on the integration of SOA, BPM and BRM. The authors highlight the current research scope, point to disregarded topics and sketch out multidisciplinary research approaches.

Findings

While the three concepts are often discussed only in isolation or pairwise, approaches that integrate them are scarce. Against this backdrop, this study defines three types of research opportunities and identifies several directions for future research that should be explored from a technological as well as organizational perspective. Given the breadth of open questions, the authors present sources for each area of our research framework, which can serve as starting points for future investigations.

Practical implications

Except for well-established support for separate tasks and technologies, there is a lack of integrated standards, methods and platforms, which for example enable integrated decision-making across BPM and SOA.

Originality/value

Our contribution builds on established frameworks and clearly shows that the discussion on the integration of SOA, BPM and BRM cannot yet be regarded as sufficient. The research agenda highlights which areas explicitly benefit from a more precise consideration.

Abstract

Nobody concerned with political economy can neglect the history of economic doctrines. Structural changes in the economy and society influence economic thinking and, conversely, innovative thought structures and attitudes have almost always forced economic institutions and modes of behaviour to adjust. We learn from the history of economic doctrines how a particular theory emerged and whether, and in which environment, it could take root. We can see how a school evolves out of a common methodological perception and similar techniques of analysis, and how it has to establish itself. The interaction between unresolved problems on the one hand, and the search for better solutions or explanations on the other, leads to a change in paradigma and to the formation of new lines of reasoning. As long as the real world is subject to progress and change scientific search for explanation must out of necessity continue.

Abstract

Purpose

Meta‐analytic evidence exists that the numerical dominance of one gender group among employees can affect the behaviour of female and male leaders. The purpose of this paper is to hypothesis that leaders will show more transformational behaviour when they hold a minority status. Transformational behaviour might help to mitigate discrepancies between male leaders' gender and the feminine context, as well as between female leaders' gender and the masculine leadership role.

Design/methodology/approach

N1=455 team members answered questionnaires about their work satisfaction and their team leaders' transformational leadership, whilst N2=142 team leaders answered questions regarding their teams' goal fulfillment.

Findings

Female and male leaders are rated more transformational in economic sectors and working groups where they hold a minority status. The paper finds a positive interrelation between transformational leadership and followers' work satisfaction for male leaders, but not for female leaders.

Research limitations/implications

Future research should compare female and male leaders from extremely gender‐typed economic sectors and from higher levels of the organisational hierarchy. This would provide evidence whether the findings could be generalised to other samples.

Practical implications

The findings point to the potential advantage of being a high‐transformational male leader in female‐dominated contexts. Irrespective of the numerical dominance of one gender group, followers of low‐transformational female leaders are more satisfied than those of low‐transformational male leaders.

Originality/value

The paper uses sector‐level (gender‐typicality of economic sectors) as well as group‐level data (gender‐composition of working groups) to account for the numerical dominance of female and male employees.

Abstract

Purpose

This research investigates the effects of multidimensional brand experiences (i.e. behavioral, intellectual, affective and sensory) on brand authenticity and brand love from the Asian consumers' perspective.

Design/methodology/approach

This research collected primary data from 418 consumers on global brands, and it tested the proposed hypotheses by using partial least squares structural equation modeling (PLS-SEM).

Findings

The findings indicate that sensory and affective experiences have direct significant impacts on brand love, while intellectual and behavioral experiences have nonsignificant impacts on brand love. Overall, intellectual, behavioral, affective and sensory experiences positively influence brand authenticity, which in turn have substantial positive impacts on brand love.

Research limitations/implications

This study investigated consumer behavior in a broader sense, and consumers from 13 Asian countries participated in this research. Future research may collect data on a larger scale from Asian countries to generalize the results.

Practical implications

By following brand authenticity as an essential positioning tool and implementing several experiential marketing strategies, global managers can develop brand-loving consumers in Asia.

Originality/value

Under the parasol of attribution theory, this research explores the relationships among the multidimensional brand experiences, brand authenticity and brand love from the Asian perspective.
