The public distribution system (PDS) is an Indian food security system established to manage the distribution of food grains at affordable prices. As a result of the population explosion, the long-established PDS system finds it challenging to maintain operational efficiency, quality, trust and transparency. This paper explores the possibility of leveraging blockchain technology to overcome these operational hurdles.

Through a literature review and expert interactions, the present research identifies critical success factors in terms of enablers and barriers that influence the adoption of blockchain technology in PDS. Furthermore, we propose two independent interpretive structural models (ISM) and MICMAC to characterize these attributes.

The research identifies 15 distinct enablers and ten barriers that influence the diffusion of the latest technology in the sector at focus. The analyses disclose the interrelationships/dependencies among these enablers and between barriers, along with their individual driving power and dependence power.

The research showcases the importance of automating the system and illustrates how the features of blockchain technology can assist in augmenting stakeholder satisfaction levels. However, poor or nonexistent government regulations and patronage are found to be the major impediments to adoption. The research also delineates the cost implications of this barrier through its interrelationships with other barriers.

Interesting inferences are drawn from the models that offer actionable insights for the industry, government and technologists for improving PDS performance. Such interventions will ensure national food security through enhanced trust and transparency, which can further improve efficiency and effectiveness.

Surface acoustic wave (SAW) sensors have attracted great attention worldwide for a variety of applications in measuring physical, chemical and biological parameters. However, stability has been one of the key issues which have limited their effective commercial applications. To fully understand this challenge of operation stability, this paper aims to systematically review mechanisms, stability issues and future challenges of SAW sensors for various applications.

This review paper starts with different types of SAWs, advantages and disadvantages of different types of SAW sensors and then the stability issues of SAW sensors. Subsequently, recent efforts made by researchers for improving working stability of SAW sensors are reviewed. Finally, it discusses the existing challenges and future prospects of SAW sensors in the rapidly growing Internet of Things-enabled application market.

A large number of scientific articles related to SAW technologies were found, and a number of opportunities for future researchers were identified. Over the past 20 years, SAW-related research has gained a growing interest of researchers. SAW sensors have attracted more and more researchers worldwide over the years, but the research topics of SAW sensor stability only own an extremely poor percentage in the total researc topics of SAWs or SAW sensors.

Although SAW sensors have been attracting researchers worldwide for decades, researchers mainly focused on the new materials and design strategies for SAW sensors to achieve good sensitivity and selectivity, and little work can be found on the stability issues of SAW sensors, which are so important for SAW sensor industries and one of the key factors to be mature products. Therefore, this paper systematically reviewed the SAW sensors from their fundamental mechanisms to stability issues and indicated their future challenges for various applications.

The extant literature on expatriate adjustment primarily highlights the role of host country nationals (HCNs) in supporting expatriates during international assignments. However, there is a dearth of research exploring the expatriates’ socialization process in establishing interpersonal relationships with HCNs. Additionally, the pivotal element of expatriates seeking credible HCN sources, fundamental for fostering these relationships for adjustment, remains largely unexamined in the context of expatriate literature. Thus, this study addresses these gaps by proposing a conceptual model to provide a more comprehensive understanding of the expatriate adjustment process.

This conceptual paper draws upon the theoretical framework of social identity theory to elucidate how socialization processes initiated by the parent organization and the expatriate shape the expatriate’s perception of HCN credibility. This perception, in turn, serves as the foundation for building a robust support system, ultimately leading to expatriate adjustment.

The proposed model explores the nuanced dimensions of expatriate adjustment, emphasizing the complex dynamics between expatriates and host country nationals during individualized socialization. This model aims to assess the credibility of HCNs in the eyes of expatriates and understand the role of the institutionalized socialization process. Further, the model investigates the influence of perceived similarity traits in the examined relationship, shedding light on the interplay of these factors and their impact on the expatriate’s adjustment to the international assignment.

The study’s findings offer practical insights for organizations looking to enhance their support systems for expatriates, emphasizing the importance of nurturing interpersonal relationships and the credibility of HCNs.

This study contributes to the expatriate literature by shedding light on the often-overlooked interpersonal relationship between expatriates and HCNs. Doing so opens new avenues for further research, offering a fresh perspective on the expatriate adjustment process.
