Social media use by undergraduate students of education in Nigeria: a survey
Authors: Wickramanayake Lalith , Muhammad Jika Saidu 
Published: December 2017

PurposeThis paper aims to investigate teacher students’ perceptions, intentions, experiences, attitudes, opinions and barriers concerning social media use and impact of social media on their learning process.Design/methodology/approachA stratified sampling technique was applied to draw the sample, and 242 teacher students were selected as a sample from three higher educational institutions in Gombe State, Nigeria. A questionnaire survey method was used to collect the data. Data analysis was by means of simple and inferential statistics.FindingsThe students widely used mobile phones to access social media, and social media was extremely popular for education, entertainment and communication among them. Educational and informational communities were also preferred by students to other social media communities. The study further revealed that effective social media usage among students enhanced their different types of skills including learning. Unstable electricity connections, security and privacy issues, internet costs and unreliable internet connections were recorded as some barriers concerning students’ social media use.Originality/valueThe outcome of this study will be a unique contribution because the pertinent literature provides little evidence or research highlights concerning teacher students’ social media use. Even more, the results of the present study may be a useful resource for university administrators, education policymakers and innovative teachers in universities – especially in developing countries and particularly Nigeria – when considering integration of modern techniques and technologies with university teaching and learning.
Developing an ontology for Greek mythology
Authors: Syamili C. , Rekha R.V. 
Published: December 2017

Purpose
The purpose of this study is to illustrate the development of ontology for the heroes of the ancient Greek mythology and religion. At present, a number of ontologies exist in different domains. However, ontologies of epics and myths are comparatively very few. To be more specific, nobody has developed such ontology for Greek mythology. This paper describes the attempts at developing ontology for Greek mythology to fill this gap.

Design/methodology/approach
This paper follows a combination of different methodologies, which is assumed to be a more effective way of developing ontology for mythology. It has adopted motivating scenario concept from Gruninger and Fox, developing cycle from Methontology and the analytico–synthetic approach from yet another methodology for ontology, and hence, it is a combination of three existing approaches.

Findings
A merged methodology has been adopted for this paper. The developed ontology was evaluated and made to meet with the information needs of its users. On the basis of the study, it was found that Greek mythology ontology could answer 62 per cent of the questions after first evaluation, i.e. 76 out of the 123 questions. The unanswered questions were analyzed in detail for further development of the ontology. The missing concepts were fed into the ontology; the ontology obtained after this stage was an exhaustive one.

Practical implications
This ontology will grow with time and can be used in semantic applications or e-learning modules related to the domain of Greek mythology.

Originality/value
This work is the first attempt to build ontology for Greek mythology. The approach is unique in that it has attempted to trace out the individual characteristics as well as the relationship between the characters described in the work.

Published: December 2017

PurposeThe purpose of this study is to carry out a systematic literature review for evidence-based assessment of the effectiveness of thesaurus in digital information retrieval systems. It also aimed to identify the evaluation methods, evaluation measures and data collection tools which may be used in evaluating digital information retrieval systems.Design/methodology/approachA systematic literature review (SLR) of 344 publications from LISA and 238 from Scopus has been carried out to identify the evaluation studies for analysis, and 15 evaluation studies have been analyzed.FindingsThis study presents evidences for the effectiveness of thesaurus in digital information retrieval systems. Various methods for evaluating digital information systems have been identified. Also, a wide range of evaluation measures and data collection tools have been identified.Research limitations/implicationsThe study was limited to the literature published in English language and indexed in LISA and Scopus. The evaluation methods, evaluation measures and data collection tools identified in this study may be used to design more cognizant evaluation studies for digital information retrieval systems.Practical implicationsThe findings have significant implications for the administrators of any type of digital information retrieval systems in making more informed decisions toward implementation of thesaurus in resource description and access to digital collections.Originality/valueThis study extends our knowledge on the potentials of thesauri in digital information retrieval systems. It also provides cues for designing more cognizant evaluation studies for digital information systems.
Using hot patents to explore technological evolution: a case from the orthopaedic field
Authors: Yeh Hsi-Yin , Lo Chi-Wei , Chang Kai-Shing , Chen Ssu-Han 
Published: December 2017

Purpose
This study aims to propose a visualized model of hot technology evolution to describe its development.

Design/methodology/approach
The basic concept is to divide a technological field into a timeline consisting of several patent clusters. Hot technology trajectories are then explored using their continuity, as well as the point in time at which they occur.

Findings
Patents in orthopaedics between 1999 and 2014 have been chosen as the research subjects and the field is divided into several hot technology trajectories. A further step is taken by interpreting high-frequency key terms. Three categories – spine-related materials, bone repairing materials and bone plates – have been identified.

Practical implications
The trajectories presented by evolving diagrams allow readers to understand the evolution of hot technology and help analysts to plan layout and strategies to remain competitive.

Originality/value
Patent clusters reflect the knowledge context of technology development. Previous studies have focused on only new technology evolution and have rarely explored the knowledge context of hot patents that have been frequently cited in recent years. Such patents often guide the development of technology.
Utilization of YouTube as an information resource to support university courses
Authors: Almobarraz Abdullah 
Published: December 2017

Purpose
The purpose of this paper is to explore the perceptions, attitudes and experiences of undergraduate students related to the use of YouTube as an information resource to support their learning. The use of YouTube by professors for course activities is also examined.

Design/methodology/approach
Quantitative research design based on a survey method was used by using a questionnaire tool. The collected data were analyzed using frequency and simple percentage. The sample comprises undergraduate students from the College of Computer and Information.

Findings
The general results reveal that the use of YouTube in the classroom influences student engagement. Students’ understanding of the importance of YouTube was determined in this study. However, professors do not seem to have positive attitudes towards incorporating YouTube into course activities.

Originality/value
The application of social media tools in Saudi Arabia is unclear because of the lack of studies that focus on the use of video-sharing websites by university students. This paper is the first of its kind conducted to explore the use of YouTube in the academic environment as an information resource to support university courses.
Public libraries: roles in Big Data
Authors: Zhan Ming , Widén Gunilla 
Published: December 2017

Purpose
The purpose of this paper is to explore the roles of public libraries in the context of Big Data.

Design/methodology/approach
A mixed method approach was used and had two main data collection phases. A survey of public libraries was used to generate an overview of which professional roles connect public libraries with Big Data. Eight roles were identified, namely, educator, marketer, data organiser, data container, advocator, advisor, developer and organisation server. Semi-structured interviews with library directors and managers were then conducted to gain a deeper understanding of these roles and how they connect to the library’s overall functions.

Findings
Results of the survey indicated that librarians lack a proper comprehension of and a pragmatic application of Big Data. Their opinions on the eight roles are slightly stronger than neutral. However, they do not demonstrate any strong agreement on these eight roles. In the interviews, the eight roles attained more clear support and are classified into two groups: service-oriented and system-oriented roles.

Originality/value
As an emerging research field, Big Data is not widely discussed in the library context, especially in public libraries. Therefore, this study fills a research gap between public libraries and Big Data. In addition, Big Data in public libraries could be well managed and readily approached by citizens in undertaking such roles, which entails that public libraries will eventually benefit from the Big Data era.
E-book and print book price and desirability for university libraries: a comparative study
Authors: Rao K.N. , Kumar Sunil , Tripathi Manorama 
Published: December 2017

Purpose
The purpose of this paper is to compare the prices of print and electronic versions of the same scholarly titles charged from a university library. This study also examines whether preferences for print or electronic formats differ with disciplines and whether high preferences for the electronic version in particular disciplines lead to tagging of high prices for e-books in those disciplines. This study evaluates association in prices of e-books and their print versions for scholarly books. It also explains trends in gaps of prices of electronic and their print versions over the time to understand changing price policy of e-books with time.

Design/methodology/approach
This is a case study analysing and interpreting prices of 717 book titles available in electronic and print versions out of 1248 book titles recommended by the faculty members of the Jawaharlal Nehru University (JNU) in early 2014. The minimum prices quoted by publishers or aggregators for these books became the secondary data for the study. The research methodology is based on quantitative descriptive and inferential statistical techniques.

Findings
The study statistically rejected the hypothesis that price tags of electronic and print versions of books do not differ significantly. E-books are usually more expensive than their print counterparts. They are more highly priced in disciplines, where the users prefer electronic books over the print ones. There is a moderate association in prices of electronic and their print versions; libraries can estimate about the budget which would be required for procuring books in electronic format with the help of price of print version; however, the accuracy of this stipulation would be only 20 per cent. The study has highlighted that 95.4 per cent of the scholarly e-books in English medium are published in the USA and the UK. The university presses of Cambridge, Oxford, Columbia, Princeton and MIT and commercial publishers like Routledge, Palgrave Macmillan, Ashgate and Springer are the major publishers and providers of the scholarly e-books.

Originality/value
This study provides insights into pricing policy of electronic and their print versions of scholarly book titles for libraries. Thus it may be relevant and helpful for library administrators in informed decision making while developing their collections for books.
Factors influencing students’ satisfaction in using wireless internet in higher education
Authors: Islam A.Y.M. Atiquil , Mok Magdalena Mo Ching , Xiuxiu Qian , Leng Chin Hai 
Published: December 2017

PurposeIn this age of exponential knowledge growth, where wireless internet is playing a dominant role, the concerned authorities of higher education have to ensure that this tool remains within the reach of the students. However, there has been as yet little research indicating its success in China. This paper aims to examine factors that influence students’ satisfaction (SAT) in using wireless internet in higher education for the purpose of learning. The second aim of this study is to identify if gender has a moderating effect on students’ SAT in using wireless internet in higher education.Design/methodology/approachData from a total of 283 students from five colleges of a comprehensive public university in China (Foreign Language Studies, Business, Education, Biology and Chemistry, and Mathematics and Engineering) were collected for this study. The reliability and validity of the measurement scale were established through a Rasch model using Winsteps version 3.94. The technology satisfaction model (TSM) was validated applying structural equation modelling (SEM) using AMOS to test the causal relationships among the constructs.FindingsThe results of this study revealed that students’ SAT was directly influenced by perceived usefulness (PU) and ease of use of wireless internet. Besides, students’ perceived ease of use (PEU) and usefulness were directly affected by their computer self-efficacy. On the other hand, students’ computer self-efficacy had an indirect effect on their SAT mediated by ease of use and perceived usefulness, respectively. The findings also discovered that gender did exert effect as a moderating variable towards students’ SAT in using wireless internet in higher education.Practical implicationsThe TSM was shown to be a useful model to measure students’ SAT in using wireless internet in a different culture.Originality/valueTo achieve this aim, a TSM on the potential factors contributing to student SAT was developed from the literature and validated in this study. Whereas, the TSM has been developed and validated in Malaysia.
A study on a content-based image retrieval technique for Chinese paintings
Authors: Hung Chia-Ching 
Published: December 2017

Purpose
The purpose of this study is to build a database of digital Chinese painting images and use the proposed technique to extract image and texture information, and search images similar to the query image based on colour histogram and texture features in the database. Thus, retrieving images by this image technique is expected to make the retrieval of Chinese painting images more precise and convenient for users.

Design/methodology/approach
In this study, a technique is proposed that considers spatial information of colours in addition to texture feature in image retrieval. This technique can be applied to retrieval of Chinese painting images. A database of 1,200 digital Chinese painting images in three categories was built, including landscape, flower and figure. The authors develop an image-retrieval technique that considers colour distribution, spatial information of colours and texture.

Findings
In this study, a database of 1,200 digital Chinese painting images in three categories was built, including landscape, flower and figure. An image-retrieval technique was developed that considers colour distribution, spatial information of colours and texture. Through adjustment of feature values, this technique is able to process both landscape and portrait images. This technique also addresses liubai (i.e. blank) and text problems in the images. The experimental results confirm high precision rate of the proposed retrieval technique.

Originality/value
In this paper, a novel Chinese painting image-retrieval technique is proposed. Existing image-retrieval techniques and the features of Chinese painting are used to retrieve Chinese painting images. The proposed technique can exclude less important image information in Chinese painting images for instance liubai and calligraphy while calculating the feature values in them. The experimental results confirm that the proposed technique delivers a retrieval precision rate as high as 92 per cent and does not require a considerable computing power for feature extraction. This technique can be applied to Web page image retrieval or to other mobile applications.

Published: December 2017

PurposeThe study aims to showcase public sentiments via social media, Twitter, during 2014 floods of Jammu and Kashmir, India.Design/methodology/approachThe study is based on content analysis of tweets related to Kashmir floods. Search was performed with “#kashmirfloods” and was confined to tweets posted from 4 September 2014 through 3 November 2014. A naturalistic approach was applied to examine the content and classify tweets into 5 major and 25 sub categories. Data as such collected were tabulated in SPSS 21 for analysis.FindingsDuring the study period, individuals, news channels, and organisations posted a total of 36,697 tweets related to Kashmir floods. It all started with an outburst of tweets which goes on declining (exponentially) with every passing day. People express themselves in a number of ways with informational tweets used more during the time of disaster. Individuals expressing their sentiments outscore other types of sentiments with text-based tweets ranking high. About 44 per cent of tweets were retweeted, and nearly 31 per cent tweets were marked favourite. Comparatively, more number of informational and help tweets were retweeted or marked favourite. Contextual richness of tweet (i.e. number of embedded expressions) enhances its visibility by means of getting liked and/or retweeted. A statistically significant positive association is observed between the number of expressions in a tweet and the number of times it is liked (favourite) or retweeted.Research limitations/implicationsTwitter plays a pivotal role during natural calamities like Kashmir floods to connect people in the hour of need and help. It provides a platform where the plight of people is heard across the globe and which encourages people to unite and overcome hurdles together.Originality/valueThis study examines the sentiments of people expressed during Jammu and Kashmir (India) Floods 2014 on social media – Twitter.
Corporate boards, ownership structures and corporate disclosures
Authors: Alnabsha Abdalrhman , Abdou Hussein A. , Ntim Collins G. , Elamer Ahmed A. 
Published: January 2018

Purpose
The purpose of this paper is to investigate the effect of corporate board attributes, ownership structure and firm-level characteristics on both corporate mandatory and voluntary disclosure behaviour.

Design/methodology/approach
Multivariate regression techniques are used to estimate the effect of corporate board and ownership structures on mandatory and voluntary disclosures of a sample of Libyan listed and non-listed firms between 2006 and 2010.

Findings
First, the authors find that board size, board composition, the frequency of board meetings and the presence of an audit committee have an impact on the level of corporate disclosure. Second, results indicate that ownership structures have a non-linear effect on the level of corporate disclosure. Finally, the authors document that firm age, liquidity, listing status, industry type and auditor type are positively associated with the level of corporate disclosure.

Research limitations/implications
Future research could investigate disclosure practices using other channels of corporate disclosure media, such as corporate websites. Useful insights may be offered also by future studies by conducting in-depth interviews with corporate managers, directors and owners regarding these issues.

Practical implications
The evidence relating to the important role that corporate governance mechanisms play in shaping the expectations relating to the level of corporate voluntary and/or mandatory disclosures may be useful in informing investor decisions, as well as future policy and regulatory initiatives.

Originality/value
This paper contributes to the existing literature by examining the governance-disclosure nexus relating to both mandatory and voluntary disclosures in both listed and non-listed firms operating in a developing country setting.
Leadership styles and self-efficacy in determining transfer intentions of safety training
Authors: Vignoli Michela , Mariani Marco Giovanni , Guglielmi Dina , Violante Francesco Saverio 
Published: December 2017

PurposeThis study aims to investigate the factors that can influence the transfer process of training in open skills, i.e. non-technical skills (NTS). Specifically, according to the model of the transfer process, the aim of this paper is to analyse the effects of both personal (e.g. self-efficacy) and work environment (e.g. safety leadership styles) antecedents of intention to transfer.Design/methodology/approachA total of 88 workers belonging to two different plants of the same chemical company filled in a questionnaire at the beginning (T1) and at the end (T2) of the training intervention. The majority of the sample was composed of men (95.5 per cent), with the mean age being 45.19 years old, and they had worked in the same company for an average of 17.2 years. Personal (self-efficacy) and organizational (transformational and passive leadership) factors were measured at T1, while intention to transfer was measured at T2. To investigate the combined effect of both personal and environmental characteristics on the transfer process, a moderation analysis was conducted following the Preacher and Hayes approach.FindingsResults showed that all the antecedents investigated (except for passive leadership) impacted on the intention to transfer. Furthermore, high levels of self-efficacy combined with higher levels of transformational leadership resulted in higher levels of intention to transfer.Research limitations/implicationsThe sample size is quite small, and effective transfer of NTS has not been measured.Practical implicationsResults suggest that organizations should focus on fostering self-efficacy of the trainees and transformational leadership of the supervisors so as to facilitate the transfer process of NTS.Originality/valueTo the best of the authors’ knowledge, this is the first study which has considered both individual and contextual characteristics to analyse the transfer process of NTS.
