Abstract
Purpose
This paper evaluates an alternative queuing concept for marine container terminals that utilize a truck appointment system (TAS). Instead of having all lanes providing service to trucks with appointments, this study considers the case where walk-in lanes are provided to serve those trucks with no appointments or trucks with appointments but arrived late due to traffic congestion.
Design/methodology/approach
To enable the analysis of the proposed alternative queuing strategy, the queuing system is shown mathematically to be stationary. Due to the complexity of the model, a discrete event simulation (DES) model is used to obtain the average waiting number of trucks per lane for both types of service lanes: TAS-lanes and walk-in lanes.
Findings
The numerical experiment results indicated that the considered queuing strategy is most beneficial when the utilization of the TAS lanes is expected to be much higher than that of the walk-in lanes.
Originality/value
The novelty of this study is that it examines the scenario where trucks with appointments switch to the walk-in lanes upon arrival if the TAS-lane server is occupied and the walk-in lane server is not occupied. This queuing strategy/policy could reduce the average waiting time of trucks at marine container terminals. Approximation equations are provided to assist practitioners calculate the average truck queue length and the average truck queuing time for this type of queuing system.

Abstract
When port authorities or terminal operators set the free time or increase storage density, the decision is often made without a clear understanding of their effects on throughput and rehandling productivity. This is partly because practical methods that deal specifically with the effect of dwell time on throughput and productivity are limited in the literature; hence the motivation for this work. This paper introduces simple methods to evaluate the effect of container dwell time and storage policies on import throughput, storage density, and rehandling productivity. The analysis considers two import storage strategies 1) non-mixed - no stacking of new import containers on top of old ones, and 2) mixed - stacking of new import containers on top of old ones. The results highlight the effect dwell time has on throughput and rehandling productivity. For the non-mixed storage policy, the increasing container dwell time lowers throughput and average stack height - resulting in an increase in rehandling productivity. On the other hand, for the mixed storage policy, the increasing container dwell time raises throughput and average stack height - resulting in a decrease in rehandling productivity. Using the presented methods, port authorities and terminal operators are able to assess and quantify the benefits of their decisions regarding container free time and subsequently make an informed decision.

Abstract
Population ageing, coupled with economic uncertainty and a shifting workforce structure, has directed the attention of public and organizational policy makers toward the potential contribution of older workers and skilled migrants in meeting labor supply shortages in ageing populations. This chapter presents labor supply and demand scenarios for 10 OECD countries and examines trends in the labor force participation of older workers against the backdrop of changes to the nature of work in an era of globalization, casualization, and, increasingly, automation. Brief analysis of each country’s situation and policy responses indicates that China, Japan, and Korea stand out as being at particular risk of being unable to maintain growth without undertaking drastic action, although their areas of focus need to differ. A limitation of the study is that GDP projections used in labor demand analysis were based on historical rates and represented past potential and a long-run average of historic economic output. Future research might also undertake comparative analysis of case studies addressing different potential solutions to workforce ageing. A key implication of the study is that there is a need to take a blended approach to public policy regarding older workers in a changing labor market. Where migration has historically been a source of labor supplementation, this may become a less viable avenue over the near future. Future shortfalls in labor imply that economies will increasingly need to diversify their sources of workers in order to maintain economic growth. For public policy makers the challenge will be to overcome public antipathy to migration and longer working lives.

Abstract
Purpose
Team social capital (TSC) has been attracting increasing research attention aiming to explore team effectiveness through within- and cross-team resource conduits. This study bridges two disconnected theories – TSC and evolutionary theory – to examine gaming clans and analyzes mechanisms of the clans' TSC building from an evolutionary perspective.
Design/methodology/approach
This research draws longitudinal data from a sample of gaming teams (N = 1,267) from anonymized player data from the game World of Tanks spanning 32 months. The authors explored teams' evolutionary patterns using hidden Markov models and applied longitudinal multilevel modeling to test hypotheses.
Findings
The results showed that teams of different sizes and levels of evolutionary fitness vary in team closure and bridging social capital. The authors also found that larger teams are more effective than smaller ones. The positive association between team-bridging social capital and effectiveness is more substantial for smaller teams.
Originality/value
This research advances the theoretical development of TSC by including the constructs of teams' evolutionary status when analyzing strategic social capital building. Adding to existing literature studying the outcome of TSC, this research also found a moderating effect of team size between TSC and effectiveness. Finally, this study also contributes to a longitudinal view of TSC and found significant evolutionary patterns of teams' membership, TSC, and effectiveness.

Abstract
Advances in Econometrics is a series of research volumes first published in 1982 by JAI Press. The authors present an update to the history of the Advances in Econometrics series. The initial history, published in 2012 for the 30th Anniversary Volume, describes key events in the history of the series and provides information about key authors and contributors to Advances in Econometrics. The authors update the original history and discuss significant changes that have occurred since 2012. These changes include the addition of five new Senior Co-Editors, seven new AIE Fellows, an expansion of the AIE conferences throughout the United States and abroad, and the increase in the number of citations for the series from 7,473 in 2012 to over 25,000 by 2022.

Abstract
Purpose
This study investigates the short-run and long-run impacts of agricultural credit on Vietnam's agricultural GDP over the period 2004:Q4–2016:Q4, with the incorporation of agricultural labor, public investment and rainfall as important determinants of agricultural GDP.
Design/methodology/approach
This study applies the indicator saturation (IS) break tests and the autoregressive distributed lag (ARDL) bounds test with structural breaks to examine the credit–agricultural performance nexus. The causal relationships among variables are explored through the Toda–Yamamoto Granger causality test.
Findings
The results indicate that agricultural credit positively influences agricultural GDP in both the short-run and long-run. A unidirectional causal relationship running from credit to agricultural GDP is confirmed. The results also discover the positive and significant effects of labor and rainfall on agricultural GDP in the long-run.
Practical implications
The results imply that the government should focus on expanding agricultural credit as well as enhancing the efficiency of agricultural credit. Furthermore, formal credit institutions should be encouraged to work closely with farmers and agricultural enterprises to offer flexible lending periods and amounts to meet the real situation of agricultural production.
Originality/value
This study is the first to examine the credit–agricultural performance relationship at the macro-level in Vietnam. Based on the empirical results, the study provides crucial implications for policymakers to optimize the effectiveness of agricultural credit and enhance nationwide agricultural performance.

Abstract
Purpose
The purpose of this study was to examine hedonic hunger at the end of the Ramadan fasting.
Design/methodology/approach
Data were collected by the Power of Food Scale (PFS), Food Craving Questionnaire-Trait (FCQ-T) and the Visual Analogue Scale. All data were taken twice at the beginning and end of Ramadan fasting.
Findings
A total number of 105 volunteers (43.8% female and 56.2% male) participated in a cross-sectional study. Ramadan fasting associated with PFS food tasted sub-factor, whereas no association was found on PFS aggregate and other PFS domain factors. Participants had higher PFS food tasted domain score at the end of the Ramadan fasting than before Ramadan fasting (p < 0.001). Total FCQ-T score as well as all sub-domains did not differ significantly. Females desired to consume carbonated beverages more, whereas in male (p = 0.04), ice cream was the most craved food.
Originality/value
The findings of this study provide data to the literature about the relation between Ramadan fasting and hedonic hunger. Ramadan fasting appears to have an influence on pleasure at first bite. The effect of Ramadan fasting on hedonic hunger should be tested with larger samples and controlled trials.

Abstract
Purpose
This study aims to reveal the impact mechanism of franchisor-owned resources, franchise relationship quality and franchisee's dynamic capabilities on franchisee performance, with the moderating role of cultural sensitivity.
Design/methodology/approach
The sample consisted of 290 middle managers and team leaders at 113 hotels and food and beverage settings participating in the international- and domestic franchises in Ho Chi Minh City, Vietnam. A partial least squares structural equation model (PLS-SEM) is used to analyse the data.
Findings
The result reveals that franchisor-owned resources, franchise relationship quality and franchisee's dynamic capabilities significantly impacted franchisee performance. Furthermore, cultural sensitivity has a beneficial role in the effect of franchise relationship quality on franchisee performance.
Originality/value
This study develops an integrated analytical framework of franchisee performance from the franchisee's perspective, contributing to integrating international business theory in franchising studies, namely the resource-based view, dynamic capability view and relationship-marketing theory.
