The purpose of this paper is to analyze how the coronavirus disease 2019 (COVID-19) countermeasures will affect the financing of the North American leagues. In particular, we focus on the missed revenue from gate receipts for the Big Four leagues.

The authors forecast the 2020 revenue for each of the four major leagues under two scenarios: (1) expected revenue under the normal conditions of fans in attendance and (2) expected revenues in the absence of fans due to the countermeasures in place. Then, the authors calculate the loss in gate receipts as a difference in the revenue under fans and no-fans scenarios.

Based on the current estimates, the combined financial loss of the clubs from NFL, MLB, NBA and NHL is expected to be above 6.8bn dollars in gate receipts alone.

The findings are useful to the league management to prepare for the suboptimal financial situation.

To the best of our knowledge, this is the first study that explores the effect of the COVID-19 pandemic across the major league sports leagues in North America.

Revenue sharing is ubiquitous among North American professional sports leagues. Under pool revenue sharing, above-average revenue teams of a league effectively transfer revenues to below-average revenue teams. Herein, the authors find and prove that a league will vote into policy a pool revenue sharing arrangement if and only if mean team revenue is greater than presharing median revenue, where this condition is equivalent to the presence of positive nonparametric skewness in a league’s distribution of team revenues. This represents a median voter theorem for league revenue sharing.

The authors consider the case of revenue sharing for the National Football League (NFL), a league that pools and equally shares national revenues among member teams.

The authors find evidence of positive and significant nonparametric skewness in NFL team revenue distributions for the 2004–2016 seasons. This distribution is observed amid annual majority rule votes of League owners in favor of maintaining the incumbent pool revenue sharing model (as opposed to no team revenue sharing). Distribution of revenues – namely the existence of outlying large market NFL teams – appears to consistently explain the historical popularity of NFL revenue sharing.

The median voter theorem uncovered in the case of NFL applies to all professional sports leagues and can be used predictively as well as descriptively.

The current era of the fourth industrial revolution has attracted significant research on the use of digital technologies in improving construction project delivery. However, less emphasis has been placed on how these digital tools will influence the management of the construction workforce. To this end, using a review of existing works, this chapter explores the fourth industrial revolution and its associated technologies that can positively impact the management of the construction workforce when implemented. Also, the possible challenges that might truncate the successful deployment of digital technologies for effective workforce management were explored. The chapter submitted that implementing workforce management-specific digital platforms and other digital technologies designed for project delivery can aid effective workforce management within construction organisations. Technologies such as cloud computing, the Internet of Things, big data analytics, robotics and automation, and artificial intelligence, among others, offer significant benefits to the effective workforce management of construction organisations. However, several challenges, such as resistance to change due to fear of job loss, cost of investment in digital tools, organisational structure and culture, must be carefully considered as they might affect the successful use of digital tools and by extension, impact the success of workforce management in the organisations.

In this paper, using Monte Carlo simulations (MCSs) under the metropolis algorithm, the authors study the magnetic properties of the yttrium-based Heusler alloys: Y₂CrGa and YFeCrGa. In the first step, the authors elaborate and discuss the ground-state phase diagrams of the more stable configurations. It is worth to note that the full-Heusler alloy Y₂CrGa contains only one magnetic atom (Cr), while the quaternary Heusler alloy YFeCrGa has two magnetic atoms (Cr and Fe). This leads to modeling of the compound Y₂CrGa by a Hamiltonian containing only one magnetic spin moment (S = 2), while the quaternary Heusler alloy YFeCrGa is modeled by a Hamiltonian containing two magnetic spin moments (Q = 5/2 and s = 2). The results of the study reveal that the critical temperature increases when increasing the reduced crystal field for the two studied compounds. To complete this study, the authors elaborated the hysteresis cycles of the two yttrium-based Heusler alloys: Y₂CrGa and YFeCrGa.

In this paper, the authors study the magnetic properties and the critical behavior of the yttrium-based Heusler alloys, Y₂CrGa and YFeCrGa, using MCSs under the metropolis algorithm. In the first step, the authors elaborate and discuss the ground-state phase diagrams of the more stable configurations for the both structures at null temperature (T = 0). On the other hand, for non-null temperature (T ≠ 0), the authors investigate the critical behavior of these two yttrium-based Heusler alloys: Y₂CrGa and YFeCrGa.

The study aims explore the prevalence of lonliness among married adults in India along with examining its association with marital quality and age.

A total of 1,084 married adults across four age-groups were included in the sample of the study. Semi-structured questionnaire for demographic details with validated psychometric instruments like Marital Quality Scale (MQS) (Shah, 1995) and UCLA Loneliness Scale (version 3) (Russell, 1996) were used to collect the data. The data was analysed using multiple regression, cross-tabulation, chi-square(χ²) and Pearson correlation.

The study found that 46.4 % of the sample experienced moderately high level of loneliness. The participants in the age group of 31–40 years felt the maximum loneliness. 56.18 % participants of the sample experienced a severely affected marital quality. Strong and significant correlation was observed between marital quality and loneliness (r = 0.526). Negligible correlation was observed between age with loneliness (p > 0.05).

The study suggests the urgent need for interventions to enhance marital quality and should focus more on interpersonal factors such as communication style, conflict resolution, support from the spouse, increasing empathy, sexual satisfaction and intimacy rather than focusing only on demographic variables.

The study will facilitate a better understanding of the pressing need to improve marital quality of Indian adults. Emphasizing on improving communication and intimacy in the marriage will improve overall well-being thereby also reducing loneliness.

To the best of the authors’ knowledge, this study is a first of its kind to explore the interrelationship between marital quality and loneliness among such a large sample in India. It also adds to the literature in understanding the dynamics of marital relationship.

This research is about embedding service-based supply chain management (SCM) concepts in the education sector. Due to Canada's competitive education sector, the authors focus on Canadian universities.

The authors develop a framework for evaluating and forecasting university performance using data envelopment analysis (DEA) and artificial neural networks (ANNs) to assist education policymakers. The application of the proposed framework is illustrated based on information from 16 Canadian universities and by investigating their teaching and research performance.

The major findings are (1) applying the service SCM concept to develop a performance evaluation and prediction framework, (2) demonstrating the application of DEA-ANN for computing and predicting the efficiency of service SCM in Canadian universities, and (3) generating insights to enable universities to improve their research and teaching performances considering critical inputs and outputs.

This paper presents a new framework for universities' performance assessment and performance prediction. DEA and ANN are integrated to aid decision-makers in evaluating the performances of universities.

The findings suggest that higher education policymakers should monitor attrition rates at graduate and undergraduate levels and provide financial support to facilitate research and concentrate on Ph.D. programs. Additionally, the sensitivity analysis indicates that selecting inputs and outputs is critical in determining university rankings.

This research proposes a new integrated DEA and ANN framework to assess and forecast future teaching and research efficiencies applying the service supply chain concept. The findings offer policymakers insights such as paying close attention to the attrition rates of undergraduate and postgraduate programs. In addition, prioritizing internal research support and concentrating on Ph.D. programs is recommended.

By replacing traditional fossil fuels, renewable energy (RE) has the potential to become an outstanding sustainable energy supply. However, owing to technological, economic, social and legal constraints, RE is still in its early stages of development. Hence, this paper aims to analyze the sustainable development hindrances in the RE supply chain (RESC).

Twenty-three hindrances to the sustainable development of the RE industry were investigated in this research, which included a review of the expert opinion and literature. Then, a mutual relationship between the hindrances by integrating interpretive structural modeling and decision-making trial and evaluation laboratory in fuzzy environment was established. Furthermore, using the cross-impact matrix multiplication applied to a classification analysis, these hindrances were grouped.

The findings show that the important hindrances are “lack of standards for the RESC (H19), lack of entrepreneurship support (H21), lack of incentives/subsidies to encourage RE producers to compete (H30) and lack of governmental support for sustainable supply chain solutions (H31).

This research provides unique insights into the area of sustainability in RESC. To the best of the authors’ knowledge, this is the first paper to analyze the sustainability hindrances in the RESC.

Although anemia during pregnancy is common in the USA, socio-demographic factors make pregnant women enrolled in Women, Infants and Children (WIC) program more vulnerable than the general population. The purpose of this study was to examine the socio-demographic characteristics, blood hemoglobin concentrations, nutrition knowledge and potential associations among these factors in a sample of pregnant women participating in the WIC program.

A cross-sectional study using survey methodology was conducted. In total, 60 pregnant women who were between 12 and 24 weeks of gestation and were carrying a single fetus were recruited from two WIC clinics. Overall nutrition knowledge was assessed with 42 questions arranged into three subscales. Participants’ scores were transformed into tertiles. WIC program records were used to record blood hemoglobin values. Principal component analysis was used to validate the knowledge subscales. Correlational and multivariate regression analyses were conducted to examine the relationship among variables.

Prevalence of anemia among the participants was higher than the national averages. Only 10 per cent of participants scored in the high tertile for nutrition knowledge. Anemia-during-pregnancy knowledge score was positively correlated with blood hemoglobin concentrations (r = 0.23, p < 0.05), and it was also a predictor of blood hemoglobin levels (R2 = 0.364, p = 0.02).

This is the first study to report on the knowledge of anemia, anemia during pregnancy and preventive measures among pregnant women enrolled in the WIC program.
