Abstract
Purpose
The fractional order HIV model has an important role in biological science. To study the HIV model in a better way, the model is presented with the help of Atangana- Baleanu operator which is in Caputo sense. Also, the characteristics of the solutions are described briefly with the help of the advance numerical techniques for the different values of fractional order derivatives. This paper aims to discuss the aforementioned objectives.
Design/methodology/approach
In this work, Adams-Bashforth method and Euler method are used to get the solution of the HIV model. These are the important numerical methods. The comparison results also are described with the physical meaning of the solutions of the model.
Findings
HIV model is analyzed under the view of fractional and AB derivative in Atangana-Baleanu-Caputo sense. The uniqueness of the solution is proved by using Banach Fixed point. The solution is derived with the help of Sumudu transform. Further, the authors employed fractional Adam-Bashforth method and Euler method to enumerate numerical results. The authors have used several values of fractional orders to present the outcomes graphically. The above calculations have been done with the help of MATLAB (R2016a). The numerical scheme used in the proposed study is valid and fruitful, and the same can be used to explore other real issues.
Research limitations/implications

Abstract
Purpose
This study examines the impact of raising the ceiling value of Electronic Commerce Custom Declarations (ECCD) on Turkey's export performance processed via ECCD during the COVID-19 period.
Design/methodology/approach
This paper examines the impact of the pandemic conditions on Cross-Border Electronic Commerce (ECCD) exports from Turkey to 47 countries over 42 months before and during the pandemic. An empirical analysis using the Pooled Mean Group (PMG) and Mean Group (MG), Panel Autoregressive Distributed Lag (ARDL) approach was conducted to identify the factors affecting export flows.
Findings
The findings suggest that raising the ceiling of the ECCD trade is a vital factor in increasing exports. and this result is robust after controlling for pandemic conditions. On the other hand, although the COVID-19 shock mitigates the export volume of ECCD in the short run, it changes by reversal and increases the export level in the long run. Additionally, the number of COVID-19 cases and deaths in Turkey have a significant and negative impact on export flows in the short run, while they have a positive and significant effect in the long run.
Practical implications
The results of this study have practical implications for policymakers, emphasizing the potential and significance of Cross-Border E-Commerce (CBEC) trade.
Originality/value
The study is a pioneering effort in the literature of CBEC to explore how changes in the upper limit on customs declarations can affect export flows, taking into account the impact of the COVID-19 pandemic.

Abstract
The concept of “Workplace Spirituality (WPS)” in the field of management has gained great interest in the last decade, especially due to its connection with profitability. There has been a rapid increase in research related to the topic. It is assumed that employees who spend a significant part of their time at work are willing to satisfy their spiritual needs at the workplace. Such unprecedented challenges as the COVID-19 pandemic have posed many difficulties for organizations to remain agile, develop and grow, and innovate to survive. At this very moment, the importance and meaning of WPS for managers appear to have increased even more. Workplace spirituality is related to motivation, belongingness, and loyalty, and the pandemic seems to have created significant issues concerning these topics with employees. Employees have been forced to work from home due to prolonged restrictions and have faced difficulties in returning to work post-pandemic. Workplace spirituality has the potential to help employees stay motivated in their work, increase their job performance, enhance job satisfaction, and improve their mental health during this difficult period. Organizations can support their employees by implementing different practices to develop workplace spirituality. In this article, approaches to satisfy the spiritual needs of employees post-pandemic, and the efforts of workplaces to meet these needs, are examined with insights from theoretical and practical life.

Abstract
Purpose
The purpose of this paper is to investigate consumers’ willingness to accept irradiated food and the major factors related both to socio-demographic characteristics and to the perceived risk of consumers about the assumption of foods treated with novel technologies and irradiation, in particular, affecting their behavior. Consumers’ need for information has been investigated.
Design/methodology/approach
An online survey, involving 392 consumers living in Italy, was carried out to respond to the aim of the study. A Probit model was performed in order to identify major factors affecting the probability to accept food treated with ionizing radiation.
Findings
Findings show that the acceptability of irradiated foods is mainly affected by the consumers’ perceived risk to health consequent to their consumption. Equally influent are the socio-economic characteristics such as age, monthly income and geographical area in which consumers live.
Research limitations/implications
This study provides some interesting suggestions both for policy makers and managers, primarily related to the need to start an effective promotion campaign aimed to familiarize the consumers about the principles, aims and benefits of irradiation technology.
Originality/value
Very few empirical studies have been carried out in order to evaluate the acceptability of foods products treated with ionizing radiation in Italy, where exist a growing problem related to the food loss and waste, and the need for information among consumers about the irradiated foods.

Abstract
The sports field is in constant change and adaptation, which leads to a need to explore new strategies to achieve success. This is why interest in technology has increased in recent years. However, despite its undeniable importance, there is no quantitative data that provides a macroscopic view of the existing literature. Therefore, the objective of this study is to carry out a bibliometric analysis that provides structured information on the origin and academic evolution of technology in the sports field. To this end, a total of 170 articles published between 1977 and 2019 in the Web of Science (Core Collection) related to technology in sport have been analyzed. The 170 publications cover 396 authors, 134 journals, 37 countries and 261 institutions. In order to carry out the analyses, authors, journal, institution and country have been taken into account, as well as the co-authoring, co-citation and co-words networks. This information can provide an overview of the three thematic areas found: (i) technology in sport from an educational perspective, (ii) technology in sport from a medical-performance perspective, and (iii) technology in sport from a management perspective.

Abstract
Purpose
In this paper, a lifetime estimation model for the solder joint is proposed which is capable of considering both severe and running mechanical shocks which is the real case in electric converters in the automotive and aerospace applications. This paper aims to asses the reliability of the solder joint under mixed exposure of mechanical loads.
Design/methodology/approach
Mechanical failure process may put at risk the perfect performance of any kinds of electronic systems regardless of the applications they are prepared for. Observation of solder joint health in an electronic assembly under simultaneous exposure of severe and running shocks is an open problem. Three commonly used soldering compositions are considered while the electronic assembly is exposed to three well-known driving cycles.
Findings
The results show that the best performance is achieved using SAC405 soldering alloy in comparison with Sn63Pb37 and SAC387 solder alloy. Consideration of mixed exposure to the mechanical loads leads to much more accurate lifetime estimation of the solder joint in the electronic assemblies.
Originality/value
The originality of the paper is confirmed.

Abstract
Over the past three decades, the U.S. economy experienced a sharp increase in the labor-force participation of women, causing a similar increase in the demand for non-parental child care. Concurrent with these developments has been a dramatic rise in the prevalence of childhood obesity, prompting the question as to what extent the increase in child-care utilization is responsible for the growth in obesity. This chapter examines the impact of various child-care arrangements on school-age children's weight outcomes using panel data from the Early Childhood Longitudinal Study, Kindergarten Cohort (ECLS-K). An advantage of the ECLS-K for our purposes is that it tracks children's child-care arrangements between Kindergarten and the 5th grade. Our fixed-effects' results suggest that non-parental child-care arrangements are not strongly associated with children's weight outcomes. Our findings are robust to numerous sensitivity and subgroup analyses.
