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.

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.

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.

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

The study examined the effect of optimal port operations on global maritime transportation among selected ports in Nigeria.

It considered research questions such as are the ports in Nigeria functional, are the ports functioning to optimal capacity and are there challenges affecting smooth operations in the Nigerian ports? The study tested the null hypothesis which states that there is no positive and significant relationship between a functional port system and maritime transportation in Nigeria. The nonparametric statistics, chi-square, were used to analyze data. Data were gathered through a questionnaire administered to three major ports in Nigeria, namely Lagos Port Complex (LPC), Port Harcourt Old port and Warri Port.

From the analysis, findings showed that there exists a positive and significant relationship between operations in the ports and maritime transportation in Nigeria. Practical implications: The study showed that the moribund state of some ports and terminals will result in loss of jobs and huge revenue, therefore, compounding the menace of unemployment with its associated vices.

The study concludes that the operations of a functional port affect the economic growth of maritime nations. Thus, it is recommended that government and the private sector should collaborate to raise adequate capital for port development and improve the super structures (infrastructures) for optimal port operations in the country among others.

The purpose of this paper is to improve users’ search results relevancy by manipulating their explicit feedback.

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.

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.

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.

The study is novel in the sense that users’ comment, rating and referral were taken into consideration to improve their overall search experience.

This paper aims to investigate the connection between different perceived organizational cultures and information security policy compliance among white-collar workers.

The survey using the Organizational Culture Assessment Instrument was sent to white-collar workers in Sweden (n = 674), asking about compliance with information security policies. The survey instrument is an operationalization of the Competing Values Framework that distinguishes between four different types of organizational culture: clan, adhocracy, market and bureaucracy.

The results indicate that organizational cultures with an internal focus are positively related to employees’ information security policy compliance. Differences in organizational culture with regards to control and flexibility seem to have less effect. The analysis shows that a bureaucratic form of organizational culture is most fruitful for fostering employees’ information security policy compliance.

The results suggest that differences in organizational culture are important for employees’ information security policy compliance. This justifies further investigating the mechanisms linking organizational culture to information security compliance.

Practitioners should be aware that the different organizational cultures do matter for employees’ information security compliance. In businesses and the public sector, the authors see a development toward customer orientation and marketization, i.e. the opposite an internal focus, that may have negative ramifications for the information security of organizations.

Few information security policy compliance studies exist on the consequences of different organizational/information cultures.

Since its inception, mobile payment is rapidly gaining popularity over the years, and starting to replace traditional modes of payment. The usage of mobile payments has further escalated following various precautionary measures (i.e. social distancing) in curbing the transmission of the COVID-19 outbreak. However, most of the elderlies are still sceptical about the usage of mobile payment services. The current study was set to investigate the impact of functional, psychological and risk barriers that resulted in elderlies' resistance towards using such services. The impact of stickiness to cash was also examined as a moderator on the investigated relationships.

Online survey questionnaires were used to collect the responses from 400 elderly consumers at the age of 60 and above. Data analysis was then performed using the SPSS and AMOS statistical software packages.

Findings obtained acknowledged the significance of functional (i.e. perceived complexity, perceived incompatibility and perceived cost), psychological (i.e. lack of trust, inertia, and technological anxiety) and risk (i.e. privacy risk, security risk, financial risk and operational risk) barriers in influencing resistance towards mobile payment services among the elderlies. Consequently, resistance would influence their attitude and non-adoption intention; with attitude as the mediator between resistance and non-adoption intention. Finally, moderation analysis also confirmed the moderating effect of stickiness to cash towards elevating the correlation between resistance and non-adoption intention.

This study is one of the very few studies that explored the minimally investigated territory on the consequential importance of mobile payment usage among the elderlies, specifically, through extending the literature on the impact of functional, psychological and risk barriers towards the individuals' resistance. Besides, this study also successfully contributed to existing body of knowledge by highlighting the mediating role of attitude and moderating role of stickiness to cash in the interrelationships between resistance, attitude and non-adoption intention.

It has been argued that a mono product economy experiences epileptic growth because it is prone to global dynamics such as epidemic. Therefore, the need to diversify investments cannot be over-emphasized. Hence, the study examined port operation's efficiency and revenue generation in global maritime trade: implications for national growth and development in Nigeria. The objectives of the study are to identify the factors that improve efficiency in port operations, and to ascertain how efficiency of operations will affect revenue generation and national growth.

The study employed correlation and multiple regressions analyses to test the hypothesis which states that port operation's efficiency does not have positive and significant effect on revenue generation in Nigeria. A cross sectional research design and structured questionnaires were deployed in the study and simple random sampling technique was used to select the sample size of 200 respondents.

Results revealed that efficient port operations affect revenue generation and national development.

Port operations in Nigeria are bedeviled with daunting challenges that hamper smooth and efficient working port's system.

The study suggested that modern port's technologies (ICTs) be deployed to enhance operations in the ports and manpower should be trained on regular intervals to understand modern logistics management techniques in the ports. Third, government should provide port infrastructures being the backbone of efficient port system. Lastly, the private sector should be partnered with in several areas including port's concession to facilitate effective and efficient service delivery in the Nigerian ports.

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.

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.

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%.

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.

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.

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.

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.

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.

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.

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.
