The delivery of information services in higher education is increasingly relying on Web-based systems. The low adoption and underutilization of information systems have been major problems for developing countries such as Pakistan in terms of realizing their full benefits. This study aims to investigate factors affecting student use of Allama Iqbal Open University’s (AIOU) Web-based services by using the Unified Theory of Acceptance and Use of Technology (UTAUT) from the perspective of Pakistani distance education.

This study has adopted quantitative research design with the UTAUT model as a theoretical framework. A self-completion structured questionnaire-based survey has been administered to 388 master’s level students, selected through systematic sampling from the target population. The response rate was 82 per cent (318). All statistical tests have been performed using IBM SPSS (version 20.0) and Process macro for SPSS.

Findings of the model’s hypotheses reveal that performance expectancy, effort expectancy and social influence are significant predictors of student behavioural intention to use AIOU Web-based services, whereas actual student use is dependent on facilitating conditions and student behavioural intention to use. The impact of moderating variables with respect to age, gender and experience did not influence the actual use of the Web services. However, the research model significantly measured (62.1 per cent) the actual use of AIOU Web-based services by the students.

This study is delimited to the UTAUT model to investigate the phenomena. Besides this, the context of the study is the voluntary instead of mandatory usage of Web services. A study conducted in mandatory settings, in which students are bound to use Web services, may have different results.

This is the first attempt to apply the UTAUT model to investigate the factors affecting student use of Web-based services from the perspective of distance education and the findings prove strong support for the model.

This study aims to examine the research productivity of Pakistan Agricultural Research Council’s (PARC’s) researchers published during 2001–2020 by using scientometric indicators. The study explored the growth and collaborative trends along with authorship and institutional collaborative patterns at the national and international levels.

The study was conducted in four phases. Firstly, a search strategy was designed to retrieve reliable data sets. During the second phase, data from PARC research was retrieved from Scopus and Web of Science (WoS). In the third phase, the data were combined, and duplications were removed. Finally, the data were analysed using RStudio and VOSviewer.

The study identified 2,868 research publications from 16 communication channels spanning over the period of 2001–2020. The growth rate varied during the study period and the year 2020 was the most productive year of the organization. Most of the research was produced in multi-authorship and five authors were dominant. Pakistan Journal of Botany was the most preferred and cited source. Moreover, PARC research collaboration with Pakistani researchers was more than their international counterparts.

Like other research, this research has some limitations. For example, this research is based on secondary data extracted from WoS and Scopus databases, world-renowned online academic. However, researchers should keep in mind while interpreting the results of this study. Secondly, the research publications published by PARC researchers during 2001–2020 were considered. Finally, this research considered English language literature only.

The study’s key theoretical contribution is its strategy for merging WoS and Scopus in RStudio, while its findings could assist agriculture research stakeholders in identifying new areas of research, awards, promotions and identification of research gaps.

To the best of the author’s knowledge, this study is the first to use scientometric indicators to evaluate PARC’s research productivity. This detailed analysis provides a deeper understanding of PARC’s contribution to agriculture research and its potential implications.

Universities across the globe are spending an increasing amount of their budgets to offer web-based services to cater information need especially off-campus students. However, the success of web-based services depends on how well the target users are satisfied with the use of the web services. The purpose of this paper is to assess students’ satisfaction with the use of the Allama Iqbal Open University (AIOU) web-based services.

Pilot tested questionnaire-based survey was administered to collect data from a sample of 388; selected through systematic sampling technique from the study’s population consisted of master level students belonged to 11 different academic departments of the Faculty of Social Science and Humanities at the AIOU from all over Pakistan.

Based on 318 useful questionnaires, response rate 82 percent, the results show that majority of the students were satisfied with the use of at the AIOU web-based services except for online mailing books tracking system, library web OPAC and web radio service. However, t-test analysis shows that no difference was found in the opinion of male and female respondents in terms of their satisfaction with the use of the web services. ANOVA results indicate that there was no significant difference depicted in satisfaction with the use of the web services among the respondents enrolled in different disciplines of the faculty. Similarly, no significant difference was found among different age groups. Moreover, the respondents belonging to all five provinces; Punjab, Khyber Pakhtunkhwa, Sindh, Baluchistan, Gilgit Baltistan, and Federal Capital territory showed the same level of satisfaction with the use of the services. The results of regression analysis (R²=0.226) denote that both perceived usefulness and perceived ease of use significantly predicted, 22.6 percent, in students’ satisfaction with the use the web services.

The study provides valuable recommendations which may be helpful for web administration of the university to improve AIOU web-based services.

To the best knowledge, this is the first study conducted to investigate the satisfaction with the use of the university web-based services in distance education’s perspective of Pakistan.

Motivated by the enactment of non-financial reporting regulations by the European Parliament, this paper aims to investigate the impact of European Union (EU) directive 2014/95/EU on the quantity of environmental, social and governance (ESG) disclosures by the S&P Europe 350 index firms. This study also investigates whether the implementation of the non-financial information (NFI) reporting regulations influences the association between ESG disclosures and firms’ earnings risk.

To measure the impact of mandatory regulations on the quantity of ESG disclosures, this study estimates the average treatment effects using a propensity weighted sample. Then this study uses the difference-in-differences method to estimate the differences in the association between ESG disclosures and earning risk before and after implementation of the EU directive.

The results show a significant positive impact of the EU directive on the quantity of ESG disclosures for the sample European public-interest entities, which indicates that the mandatory NFI reporting requirements could boost the availability of increasingly demanded ESG related information. The enhanced association between the ESG disclosures and firms’ earnings risk during the post-directive period reveals that mandating NFI reporting also increases the quality of ESG disclosures.

Using the legitimacy and decision-usefulness theories, this study provides novel evidence concerning the impact of the EU directive on the quantity and quality of ESG disclosures.

This study aims to investigate how the presence of female CEOs (FCEOs) affects investment efficiency in emerging economy, where female participation in business activities is limited.

This paper investigates the impact of CEO gender on investment efficiency by using investment efficiency measures proposed by Biddle et al. (2009), Chen et al. (2011) and Chen et al. (2013).

The findings suggest that FCEOs are associated with high level of investment efficiency. FCEOs improve corporate governance, streamline management and reduce inefficient investment decisions. In addition, FCEOs focus more on curbing underinvestment than overinvestment when making investment decisions. Furthermore, high financial reporting quality (FRQ) strengthens the effect of FCEOs on investment efficiency. The results suggest that FCEOs do not ameliorate the investment efficiency of state-owned enterprises.

This study enhances our understanding of the effects of FCEOs on corporate investment decisions in a male-dominated society. Efficient use of resources is vital from corporate and societal perspectives. Emerging economies are characterized by the unstable political and economic environment and low participation of females in decision-making. Hence, these economies require efficient utilization of resources. This study also sheds light on the role of FCEOs in curtailing underinvestment in emerging economies. It proves that FRQ is important in emerging economies because it strengthens the governance role of FCEOs.

Multi-robot coalition formation (MRCF) refers to the formation of robot coalitions against complex tasks requiring multiple robots for execution. Situations, where the robots have to participate in multiple coalitions over time due to a large number of tasks, are called Time-extended MRCF. While being NP-hard, time-extended MRCF also holds the possibility of resource deadlocks due to any cyclic hold-and-wait conditions among the coalitions. Existing schemes compromise on solution quality to form workable, deadlock-free coalitions through instantaneous or incremental allocations.

This paper presents an evolutionary algorithm (EA)-based task allocation framework for improved, deadlock-free solutions against time-extended MRCF. The framework simultaneously allocates multiple tasks, allowing the robots to participate in multiple coalitions within their schedule. A directed acyclic graph–based representation of robot plans is used for deadlock detection and avoidance.

Allowing the robots to participate in multiple coalitions within their schedule, significantly improves the allocation quality. The improved allocation quality of the EA is validated against two auction schemes inspired by the literature.

To the best of the author's knowledge, this is the first framework which simultaneously considers multiple MR tasks for deadlock-free allocation while allowing the robots to participate in multiple coalitions within their plans.

The purpose of this paper was to systematically collect and review all studies which have been conducted on research data services in libraries across the globe.

Six world-renowned scholarly databases were searched and Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were used for the identification and selection of eligible studies. The studies were then assessed using a well-renowned framework for the quality assessment of research studies.

The results revealed that the libraries were engaged in providing different types of research data services such as identification, acquisition, management and preservation of research data. They also arranged training programs, supported the publishing and sharing of data and dealt with the licensing and copyright issues related to data.

The results of this study would be helpful for researchers and organizations, especially those engaged in educational activities, in understanding the current scenario of research data services in the world libraries. Furthermore, the findings offer valuable insights to library professionals regarding the types of research support services available globally. This would enable them to play an integral role in planning, designing and implementing such services in their libraries.

To the best of the authors’ knowledge, this study is the first of its kind that systematically collects and reviews the literature on research data services in libraries worldwide.

The purpose of this study is to explore the applications of 3D printing in space sectors. The authors have highlighted the potential research gap that can be explored in the current field of study. Three-dimensional (3D) printing is an additive manufacturing technique that uses metallic powder, ceramic or polymers to build simple/complex parts. The parts produced possess good strength, low weight and excellent mechanical properties and are cost-effective. Therefore, efforts have been made to make the adoption of 3D printing successful in space so that complex parts can be manufactured in space. This saves a considerable amount of both time and carrying cost. Thereof the challenges and opportunities that the space sector holds for additive manufacturing is worth reviewing to provide a better insight into further developments and prospects for this technology.

The potentiality of 3D printing for the manufacturing of various components under space conditions has been explained. Here, the authors have reviewed the details of manufactured parts used for zero-gravity missions, subjected to onboard international space station conditions and with those manufactured on earth. Followed by the major opportunities in 3D printing in space which include component repair, material characterization, process improvement and process development along with the new designs. The challenges like space conditions, availability of power in space, the infrastructure requirements and the quality control or testing of the items that are being built in space are explained along with their possible mitigation strategies.

These components are well comparable with those prepared on earth which enables a massive cost saving. Other than the onboard manufacturing process, numerous other components as well as a complete robot/satellite for outer space applications were manufactured by additive manufacturing. Moreover, these components can be recycled onboard to produce feedstock for the next materials. The parts produced in space are bought back and compared with those built on earth. There is a difference in their nature, i.e. the flight specimen showed a brittle nature, and the ground specimen showed a denser nature.

This review discusses the advancements of 3D printing in space and provides numerous examples of the applications of 3D printing in space and space applications. This paper is solely dedicated to 3D printing in space. It provides a breakthrough in the literature as a limited amount of literature is available on this topic. This paper aims at highlighting all the challenges that additive manufacturing faces in the space sector and also the future opportunities that await development.

This paper aims to propose a new framework for the management of a waqf land registration system in Malaysia that is compliant with Islamic law and the Malaysian legal system. The study sought to answer the following two research questions: what are the issues of the waqf land registration system and how to solve the issues of waqf land registration in Malaysia.

This study used a qualitative research method by using content analysis, legal investigation and doctrinal research. Data were collected through semi-structured interviews with lawyers, academicians and executive officers from the Department of Land and Mines, the State Islamic Religious Council and reviewed documents mainly from the Department of Waqf, Zakat and Hajj Malaysia.

A new framework for the management of waqf land registration in Malaysia was identified, which was developed based on current waqf issues such as problematic registration methods, lengthy and complicated procedures, interference in the jurisdiction of the civil court and idle waqf land. The framework overcame the flaw of the previous waqf land registration system in Malaysia.

The new framework will provide solutions to the current registration system within the National Land Code, 1965, which will secure property in the future.

This paper aims to develop efficient and simple models for thermal distribution, melt pool dimensions and controlled phase change in the laser additive manufacturing (AM) of bulk and powder particles ceramic materials.

This paper proposes new analytical models for the AM of bulk and powder bed ceramic materials. A volumetric moving heat source, along with the complete melting of bulk and powder particle materials, is taken into account. Different values of laser absorption coefficient in solid and liquid states have been used to investigate the phase transformation. Furthermore, the pores and voids dimensions are also included in the modeling. Theoretical predictions have been compared with the experimental analyses and finite element simulations in laser to silicon nitride and laser to alumina interaction. The analysis focuses on the impact of laser power and scanning speed on the melt pool width and depth evolution into the bulk substrate and powder bed.

This study shows that the powder particles exhibit a higher thermal distribution value than the bulk substrate because of voids in the powder layer. The laser beam experiences multiple reflections in the presence of porosity/voids, thus increasing the surface absorption coefficient, which becomes relevant with the increment in the pore/void dimension. A direct relationship has been found between the laser power and melt pool dimensions, while the scanning speed displayed an inverse relationship for the melt pool width and length. Larger melt dimensions were inferred in the case of laser–powder particle interaction compared with laser–bulk substrate interaction. A close correlation was found between the analytical simulations, experimental investigations and numerical simulation results within the range of 4%–8%.

This paper fulfills an identified need to develop efficient and simplified models for ceramics laser AM by taking into account different laser absorption coefficients in solid and liquid form, voids and pores dimensions and controlled phase transformation to avoid vapors and plasma formation. The limitation of the finite element simulation model is that the solution is strongly dependent on the mesh quality and accuracy directly linked to the computation efficiency and time. A finer mesh requires a longer computing time than a coarse mesh. Finite element simulations require, however, specialized skills.
