The purpose of this study is to evaluate different 3D structures for humidity sensing that will enable the fabrication of complex geometries with high moisture sensitivity.

Humidity sensors based on alumina ceramics were fabricated using direct ink write (DIW) technique. Different engineered surface area, polymer binder ratio and post-processing treatment were considered to increase moisture sensitivity.

It was found that the binder ratio plays an important role in controlling the rheology of the paste during printing and determining the pore size after post-processing treatment. The sensibility of the fabricated humidity sensor was investigated by measuring its capacitance response toward relative humidity (RH) varying from 40% to 90% RH at 25°C. It is shown that using 3D lattice design, printed alumina humidity sensor could improve sensitivity up to 31.6 pF/RH%, over an order of magnitude higher than solid alumina.

Most of the alumina humidity sensors available are films in nature because of manufacturing difficulties, which limited its potential of higher sensitivity, and thus broader applications. In this paper, a novel 3D alumina humidity sensor was fabricated using DIW 3D printing technology.

The purpose of this paper is to determine the level of efficiency in the Mexico electricity industry during the 2008-2015 period.

A data envelopment analysis (DEA) network model is proposed, where technical efficiency is calculated. A factorial analysis using the principal components method was carried out first. Later, latent dimensions were calculated through the variance criterion and sedimentation graph, where four components were presented. After performing factor rotation, the nodes were grouped: generation, transmission, distribution and sales. It proceeded later to structure a DEA network model.

From the calculations made, the most efficient node was the transmission, while the North Gulf and East Center divisions were the only efficient.

The limitations presented in this study were data collection.

The implications that were observed were that through the results obtained, proposals can be made to the Mexican electricity sector to improve each of the nodes, and have a better operation and reduce energy losses.

The social impact of this type of study is that based on the results obtained, they present the basis for improving energy policy and users can have a better service that has better quality and coverage.

The originality of this study consists in the use of two methodologies, factor analysis methodology and DEA network model.

Trust has long been viewed as a potential governance mechanism. However, recent research discloses substantive incongruities in trust conceptualization and operationalization – especially in the supply chain buyer/supplier context. The purpose of this paper is to develop an empirically grounded conceptualization of trust and to explore the trust-construction process.

The authors used the communications rationality approach to elaborate a three-stage qualitative study of supply chain trust. The authors first monologically examine trust by interviewing managers from over 50 companies (as described). The list of trust behaviors are then dialogically refined through 11 focus studies comprised of over 250 managers into different trust dimensions (as agreed upon). Finally, the authors used two in-depth, dyadic case studies to examine the dynamic trust construction process (as witnessed).

The authors find divergence in the way academics define trust and the way companies operationalize trust. Missing in action is the notion of benevolence. In the supply chain setting, managers describe trust as consisting of credibility and relationship commitment. Companies use an iterative approach to signal trustworthiness. However, ambiguity increases the costs and decreases the effectiveness of proactive trust construction as a form of supply chain governance.

The authors specify and evaluate novel constructs used to signal trustworthiness and document why and how companies struggle to use the signaling process efficiently and effectively. For some, this is an issue of managerial commitment. For others, this represents a lack of understanding of trustworthiness signals and the trust-construction process. Ultimately, the authors develop a more robust conceptualization of inter-organizational trust and present a roadmap for proactive trust construction.

This study sought to assess the process of initiating a sustainable recycling program at the University of Jordan. It illustrates the potentials of recycling, perceived awareness of recycling by the students and staff, as well as challenges to a sustainable waste recycling program. This study aims to identify the barriers and challenges that face a sustainable waste recycling program at the University of Jordan.

The study consisted of investigating waste recycling potential on campus, inspecting general environmental awareness toward recycling and running an experimental recycling study on part of the campus. A waste characterization study was conducted to assess the current waste status and recycling extent. A questionnaire survey was carried out to obtain information on the students’ and staffs’ awareness of waste recycling and management on campus. In the experimental recycling study, seventy units of waste segregation bins were distributed on campus. The recycling efficiency was evaluated at two schools; the School of Engineering and the School of Medicine. The administrative support and collaboration while running the recycling program were also observed.

Overall, waste recycling at the University of Jordan has an appreciable opportunity and potential. A substantial amount of waste can be diverted from going to the landfill. Data showed general positive recycling rates except for plastic. Also, the recycling rates show great potential for enhancing. The recycling at the University of Jordan faces several barriers and obstacles. The greatest barrier was identified as the lack of cooperation of the administrative system on campus. The administrative support for the recycling program was strong only at the initiation of the recycling program. Administrative support has a vital influence on the recycling program. It has the potential of boosting it or bringing it to halt. Future studies should focus on investigating recycling efficiency for the entire campus and focus more on increasing pro-environmental behavior among students and staff in higher education institutions.

The value of this research lies in it being conducted in a large campus university in a developing country. Also, the study used a diagnostic approach that is based on evaluating an environmental sustainability program as it evolves inside a higher education institution. The study illustrates the challenges that face universities in developing countries while adopting green campus initiatives.

The purpose of this study is to investigate the adoption of waqf technology (Waqftech) using blockchain smart contracts for corporate waqf crowdfunding. Despite the growing interest in Waqftech, Malaysian enterprises have not fully embraced this emerging technology because of uncertainty regarding the benefits it offers to contributors. The research incorporates two theoretical frameworks: the electronic data interchange (EDI) model for firms’ technology adoption, and the triple bottom line theory (TBL) for corporate social responsibility.

A quantitative method using a cross-sectional survey design with a five-point Likert scale questionnaire was used. Data was collected from 210 decision-makers representing small and medium-sized enterprises and analyzed using partial least squares-structural equation modeling.

The findings from this research suggest that Malaysian enterprises are influenced by both corporate and social predictive benefits when using blockchain crowdfunding, but not by environmental benefits. The adoption of blockchain smart contracts does not correlate with predictive environmental benefits because of misconceptions about the disruptive technology’s impact on biological and digital environmental preservation.

This research focuses on organizational behavior rather than individual users of waqf crowdfunding, and it is limited, primarily focusing within Malaysia and regions with similar waqf structures.

The Waqftech framework allows innovative mechanisms for executing corporate waqf investment returns to the intended beneficiaries through the smart contracts’ platform. In addition, this study supports relevant corporate social responsibility and creating shared value technology adoption theories, including EDI and TBL. Aside from this, the study provides empirical implications for waqf management using fintech platforms.

This groundbreaking study focuses on creating a Waqftech model for corporate waqf crowdfunding. The results of this study are important for the development of government policies that support the use of Waqftech in charitable fundraising. More research on biological and digital environmental perspectives is proposed to foster investors’ confidence in the visibility of digital tracking and lead to swift investments in future metaverse fundraising platforms.
