Development of work-life/family policy and gendered division of childcare responsibility: the case of South Korea
Authors: Yoon Seonwoo , Park Nara 
Published: July 2023

PurposeThis paper aims to overcome the limitations of studies on work-life balance, which have focused on Western countries without considering “mental” dimensions of gendered childcare. By concentrating on South Korea as a case study, this paper also aims to examine how the gendered division of childcare changed when Korea's work-life/family policy followed European work-family conciliation policy.Design/methodology/approachThe Korean Time Use Survey (KTUS) in 2009 and 2019 are used for multiple regression analyses. Based on discussions about theories on unpaid work distribution within households and its stratification effects, this study examines the relationship between wife's and husband's behaviors and the stratification effects in the gendered division of childcare alongside the work-life/family policy change.FindingsSubstantial findings indicate the necessity of strengthening various legal and institutional structures that might increase husbands' characteristics of caring masculinities. Additionally, while policies developed to support flexible working arrangements, low-income women at risk of being trapped in dual poverty of time and income should be carefully considered.Originality/valueThis study focuses especially on South Korea, thereby contributing to understanding how national policy and gendered distribution of childcare are related. Notably, this link has not been widely discussed in the literature on work-life balance. It also suggests viable directions for future policies depending on gender and socioeconomic status.
Tapping into flavourful journeys: a systematic review and application of craft beer tourism frameworks
Authors: Tham Aaron , Campton Jenna , Cooper-McKenzie Bruce 
Published: July 2023

Purpose
There is a growing interest in investigating craft beer tourism and consumption experiences as different destinations seek to position unique attributes and cultures in their culinary offerings. Yet, in this space, factors that have triggered the creation, management and marketing of craft beer tourism remain implicit. The purpose of this paper is therefore to present a systematic literature review of craft beer tourism, apply a conceptual model of craft beer gastronomy tourism and, in turn, provide strategic imperatives for the sector moving forward.

Design/methodology/approach
A comprehensive search for craft beer tourism in hospitality and tourism literature was undertaken using a combination of Google Scholar search terms as well as institutional library databases. Then, following the steps proposed by Xiao and Watson (2019), articles were sorted into themes before determining their appropriateness to be included in a systematic literature review.

Findings
Based on prior research, a Craft beer gastronomy tourism model is proposed. This model was found to provide a macro perspective of the craft beer tourism literature and was applied using the systematic literature review. It was found that not many of the papers fit the three-step process, and a fragmented relationship between craft breweries and tourism was observed. On reviewing the theories and frameworks used, it was found that there was not much consistency with the majority using frameworks and concepts. Furthermore, most studies were undertaken from the perspective of a single region or homogenous samples, with few offering cross-sectional comparisons. The most common methods of the papers were surveys and interviews, with a majority being cross-sectional.

Originality/value
The systematic literature review has led to the development of a novel conceptual model that highlights the current focal areas but also gaps that inform future studies and managerial implications.
Internationalization of research in Georgia: why to engage and with whom to engage?
Authors: Chachkhiani Ketevan , Tabatadze Shalva 
Published: July 2023

Purpose
This study aims to explore the research internationalization process in Georgia, one of the post-Soviet countries. Specifically, it examines the individual-level reasons that motivate faculty at Georgian universities to engage in the process of research internationalization. It also unpacks scholars’ perspectives on the driving factors for selecting the key partners in international research.

Design/methodology/approach
Sixteen faculty members for this exploratory qualitative study were selected through stratified purposeful sampling from five higher educational institutions in Georgia. Participants were asked to discuss their participation in international research projects and underline the activities and events that motivated them to participate in international collaborative projects. The critical incident method was used to analyze our qualitative data collected through semi-structured interviews.

Findings
The research revealed that faculty at Georgian universities are more oriented toward collaboration with their peers from European countries and the USA. This preference is influenced by such factors as higher quality of science, higher level of freedom and autonomy, personal contacts and networks, as well as language competencies. The data also helped to unpack Georgian scholars’ individual-level rationales that were conceptualized into three domains: human capital, financial capital and physical capital.

Originality/value
This study is an original work conducted in Georgia. It contributes to the development of the field of internationalization of research. The three-domain conceptual framework on the individual-level rationale for internationalization can be used in future research on post-Soviet countries and beyond.
Adapting management control to virtual teams: evidence from a natural experiment
Authors: Noto Guido , Marisca Carmelo , Barresi Gustavo 
Published: July 2023

Purpose
The COVID-19 pandemic has forced many organisations to transform face-to-face teams into virtual ones through the adoption of remote working modes. This event has represented the starting point of a process that is changing how management control (MC) systems are designed and implemented to guide employees towards organisational objectives. The previous literature on virtual teams (VTs) has devoted scant attention to MC issues. This study aims to fill this gap by exploring how MC – and particularly cultural control – has changed to cope with the shift from face-to-face to VTs and by analysing the interrelationship between the different control mechanisms and the resulting tensions.

Design/methodology/approach
The research adopts the methodological framework based on abduction to provide a theoretical explanation and conceptualisation of MC in virtual settings. To tackle the research objective, this work undertakes a cross-sectional field study based on semi-structured interviews with managers of different service companies.

Findings
The results of the research highlight the key challenges that managers are called to deal with to design and change MC systems when implementing remote working. In particular, managers must cope with the reduced possibility to leverage cultural controls. To do this, this study’s analysis found that managers act by introducing and/or removing formal and informal controls and by orchestrating the interplays and tensions between these mechanisms.

Originality/value
To the best of the authors’ knowledge, to date limited attention has been paid to MC in VTs. Moreover, few researchers have investigated the process of MC change from face-to-face to VTs. This work aims to contribute to this nascent stream of literature by providing interesting implications for both research and practice.

Authors: Balconi Michela , Angioletti Laura , Cassioli Federico 
Published: July 2023

Purpose
The purpose of this study is to investigate the effects of the remote training process on distance learning with the application of neurometrics and investigate the features of the training that promote better synchronization between trainers and trainees in terms of cognitive and emotional processes favorable to learning, during a condition of remote professional training.

Design/methodology/approach
The authors proposed a hyperscanning paradigm together with a conversational analysis to assess remote online training by collecting neurophysiological measures (frequency band analysis: delta, theta, alpha and beta) via multiple wearable electroencephalograms (EEGs) during a session of remote training.

Findings
Results showed increased delta activity in the trainer when he was leading the session and when the participants were exchanging feedback. The delivery of feedback was also linked to increased theta activity compared with the normal activity of the trainees. Finally, synchronization of EEG between trainer and trainee groups was found for the beta band.

Research limitations/implications
This study proposes to adopt a new multi-methodological approach that combines conversational analysis with the detection of remote neurometric parameters, in the field of educational neuroscience applied to organizational contexts.

Practical implications
Findings can help trainers in the development of their skills as trainers and in modeling remote training in organizations.

Originality/value
Findings highlight the crucial role of particular phases of the e-learning process, such as the feedback phase and the interaction trainer group, and they pointed out the relevance of neurophysiological measures to test the e-learning process.
High‐resolution reservoir stochastic modelling based on optimized estimation of vertical autocorrelation
Authors: Zeng Fanxin , Zhang Hongbing , Zhang Lingyuan , Shang Zuoping , Zhu Xinjie 
Published: July 2023

AbstractThe high‐resolution model of elastic properties is of great significance for fine reservoir characterization and precise oil and gas exploration. However, it is difficult to obtain a satisfactory high‐resolution reservoir model with the existing technologies. In this paper, a novel high‐resolution stochastic modelling strategy based on the fast Fourier transform moving average is proposed. In this strategy, several structural parameters are optimized to improve the rationality of the stochastic model, including vertical autocorrelation length, horizontal autocorrelation length, roughness factor and angle parameter. Among them, the optimization of the vertical autocorrelation length is crucial for vertical high‐resolution modelling. To this end, a nonlinear optimal inversion strategy of the vertical autocorrelation length is designed based on the idea of minimizing the spectral Jensen–Shannon divergence between the modelling result and the logging curve. However, nonlinear inversion is usually unstable, so it is necessary to introduce a regularization operator in the inversion to improve the stability. Considering that the heterogeneity of the subsurface medium is consistent or gradual within the stratums, but discontinuous and abrupt at the interfaces, edge‐preserving regularization is applied to obtain a blocky estimation of the vertical autocorrelation length. The optimal estimation experiment of the vertical autocorrelation length based on the measured logging data shows that the edge‐preserving regularization significantly improves the stability of the nonlinear optimal inversion, and blocky estimation results with sharp edges are obtained. Then, the optimized vertical autocorrelation length and the other structural parameters are applied to fast Fourier transform moving average modelling on an actual reservoir profile. The result shows that the resolution of the model is significantly improved, which realizes the fine reservoir characterization. In addition, the optimized structural parameters effectively constrain the small‐scale heterogeneity and ensure the rationality of the stochastic model.
New evidence on sources of macroeconomic fluctuations in sub‐Saharan African countries
Authors: Taiwo Shakirudeen , Uwilingiye Josine 
Published: July 2023

AbstractFollowing a global vector autoregressive (GVAR) approach, this paper presents new evidence on the validity of international transmission of economic shocks from key trading partners as sources of macroeconomic fluctuations in sub‐Saharan African (SSA) countries. The GVAR model was estimated for 21 SSA countries grouped into three country classes—oil‐rich, other‐resources‐rich and non‐resource‐based economies, to account for output shocks from crucial trading partner countries—United States, United Kingdom, China and Europe. Furthermore, the generalized forecast error variance decompositions results reveal that output shocks from key trading partners constitute significant contributors to changes in key macroeconomic indicators—real gross domestic product, inflation, exchange rate and short‐term interest rate, in the SSA region. The generalized impulse response functions indicate that these economic shocks have more significant impacts on oil‐rich countries than on other country groups. A key recommendation from this study is that SSA countries, especially the resource‐rich economies, need to strengthen and diversify their economic structure, including the trade basket.
Critical examination of the characterization techniques, and the evidence, for the existence of extra‐long amylopectin chains
Authors: Li Changfeng , Wu Alex , Gilbert Robert G. 
Published: July 2023

AbstractIt has been suggested that amylopectin can contain small but significant amounts of extra‐long chains (ELCs), which could affect functional properties, and also would have implications for the mechanism of starch biosynthesis. However, current evidence for the existence of ELCs is ambiguous. The amylose/amylopectin separation and the characterization techniques used for the investigation of ELCs are reviewed, problems in those techniques are examined, and studies of ELCs of amylopectin are discussed. A model for the biosynthesis of amylopectin chains in terms of conventional biosynthesis enzymes, which provides an excellent fit to a large amount of experimental data, is used to provide a rigorous definition of ELCs. In addition, current investigations of ELCs, involving separation, is hindered by the lack of a method to quantitatively separate all the amylopectin from starch without any traces of residual amylose (which would have long chains). Unambiguous evidence for the existence of ELCs can be obtained using two‐dimensional (2D) characterization, these dimensions being the degree of polymerization of a chain and the size of the whole molecule. Available 2D data indicate that there are no ELCs present in currently detectable quantities in native rice starches. However, concluding this more rigorously requires improvements in the resolution of current 2D methods.
Transcriptomic and metabolite analyses provided a new sight of 1‐MCP on organic acid metabolism in peach during storage
Authors: Cai Hongfang , Han Shuai , Wang Qingwen , Liu Xinyue , Yu Zhifang 
Published: July 2023

AbstractIn this study, “Xiahui 6” peaches were treated with 10 µL/L 1‐methylcyclopropene (1‐MCP) for 12 h and then stored at 20°C for 9 days; the regulation of 1‐MCP on organic acids during storage was investigated through transcriptomic and metabolite analyses. Results showed that 1‐MCP maintained higher gene expression of malate synthesis (PpPEPC1, PpPEPC2, and PpNAD‐cytMDH) at the end of storage but extremely inhibited the gene expression of malate degradation (PpNADP‐cytME) during storage, resulting that malate content in treated peaches was twice that of control group at day 7. Besides, the increasement of citrate synthesis and degradation‐related genes (PpmitCS, PpcytACO, PpNAD‐mitIDH, and PpNADP‐cytIDH) at days 3 and 5 was postponed by 1‐MCP treatment, accompanied by 0.5 times higher citrate content at day 7. Our results suggested that 1‐MCP has inhibitory effects on both the synthesis and degradation of organic acids; however, the inhibitory effect of 1‐MCP on organic acid degradation may be greater than that on organic acid synthesis.Practical Application: This study provides a theoretical basis for the application of 1‐methylcyclopropene (1‐MCP) in fruit preservation.
Preparation, identification, and inhibitory mechanism of dipeptidyl peptidase IV inhibitory peptides from goat milk whey protein
Authors: Du Xiaojing , Jiang Chengyu , Wang Shan , Jing Huijuan , Mo Ling , Ma Chaoyang , Wang Hongxin 
Published: July 2023

AbstractThis study explores potential hypoglycemic mechanisms by preparing and identifying novel dipeptidyl peptidase IV (DPP‐IV) inhibitory peptides from goat milk (GM) whey protein. Papain was used to hydrolyze the GM whey protein. After purification by ultrafiltration, the Sephadex column, and preparative RP‐HPLC, the peptide inhibited DPP‐IV, α‐glucosidase, and α‐amylase with IC50 of 0.34, 0.37, and 0.72 mg/mL, respectively. To further explore the inhibitory mechanism of peptides on DPP‐IV, SPPEFLR, LDADGSY, YPVEPFT, and FNPTY were identified and synthesized for the first time, with IC50 values of 56.22, 52.16, 175.7, and 62.32 µM, respectively. Molecular docking and dynamics results show that SPPEFLR, LDADGSY, and FNPTY bind more tightly to the active pocket of DPP‐IV, which was consistent with the in vitro activity. Furthermore, the first three N‐terminals of SPPEFLR and FNPTY peptides exhibit proline characteristics and competitively inhibit DPP‐IV. Notably, the first N‐terminal leucine of LDADGSY may play a key role in inhibiting DPP‐IV.
Improvements in the color, phytochemical, and antioxidant properties of frozen ripe mango pieces using calcium chloride dipping and chitosan coating
Authors: Saikaew Kawinchaya , Siripornadulsil Wilailak , Siripornadulsil Surasak 
Published: July 2023

AbstractThis study aimed to investigate the influences of a dipping/coating composed of calcium chloride (CaCl2) or chitosan on the quality of ripe mango pieces during frozen storage for 6 months. The fruits were dipped in solutions with concentrations of 0.5% and 1% for different times (15 or 30 min for CaCl2 and 1 or 15 min for chitosan). We found that treatment with 1% CaCl2 for 30 min significantly retarded the color changes with the highest L* (p < 0.05) and the lowest of b* and ∆E (p ≥ 0.05). Interestingly, treatment with 0.5% CaCl2 for 30 min significantly preserved the contents of total phenolics and total flavonoids and the antioxidant activities at values higher than the control levels, as determined by DPPH and ABTS assays (p < 0.05). Moreover, treatment with 0.5%–1% chitosan for 1 min effectively delayed the loss of moisture and weight. The results indicate that dipping in CaCl2 is an alternative simple food processing technique for improving the quality of ripe mango pieces during frozen storage that effectively delays the color changes and preserves the antioxidant content and activity.Highlights
The coating of frozen ripe mango pieces with CaCl2 and chitosan was first investigated.
CaCl2 effectively retarded the color change during storage and after thawing.
Chitosan effectively delayed the loss of moisture and weight of mango pulp.
Coating with 0.5% CaCl2 for 30 min maintained the phytochemicals and antioxidant activities.
Coating treatment can preserve mango qualities and could be commercialized with cost savings.
Practical ApplicationThe present article proposes a strategy that effectively delays the physicochemical changes and preserves the nutritional properties of mango fruit and could be commercialized with cost savings. A frozen mango can either be consumed (ready‐to‐eat frozen mango) or used as a food raw material.
Plus Token and investor searching behaviour – A cryptocurrency Ponzi scheme
Authors: Zhang Shuyu , Zhang Dunli , Zheng Jianming , Aerts Walter , Xu Dandan 
Published: July 2023

AbstractIn July 2020, the Chinese government warned that the Plus Token was a Ponzi scheme based on blockchain. More than 200 million investors were involved in this scam. We investigate how investors' search behaviour is associated with their decision making. We find that the bitcoin bag of words Baidu index is positively and significantly related to bitcoins transferred to Plus Token addresses, suggesting that public prominence of searches about bitcoin and blockchain tends to be related to investor decisions regarding the Plus Token project.
Deleveraging for talents: Human capital reliance and corporate leverage
Authors: Liu YunGuo , Zheng Minghui , Xu Yue , Xie Sujuan 
Published: July 2023

AbstractUsing data from Chinese listed firms, we develop a measure of a firm's reliance on human capital that is based on its demand for highly educated employees. We find that a high reliance on human capital is linked to low corporate leverage, and this effect is more pronounced among firms at a high risk of human capital mobility and those facing high skilled‐labour adjustment costs. Our results indicate that firms strategically manage their capital structure to maintain financial flexibility, enabling them to effectively respond to the labour‐related costs associated with human capital losses and costly labour adjustments.
Immediate and lasting effects of different regulation of craving strategies on cue‐induced craving and the late positive potential in smokers
Authors: Nickel Solvej , Endrass Tanja , Dieterich Raoul 
Published: July 2023

AbstractCraving, induced by substance‐related cues, contributes to continued substance use and relapse. Therefore, regulation of craving (ROC) is important for treatment success. Distraction involves disengaging from craving‐inducing cues; whereas, reappraisal requires engaging with potential risks of substance use. Given this difference in elaboration, we addressed the question whether reappraisal entails lasting advantages over distraction in successful ROC. To elucidate how this is implemented neurally, we examined the late positive potential (LPP) as an electrocortical indicator of motivated attention to cues. N = 62 smokers viewed smoking‐related pictures and indicated the degree of craving each picture induced. While viewing the pictures, EEG was recorded, and the participants focused on the long‐term negative (LATER) or short‐term positive (NOW) consequences of smoking or performed an arithmetic task to distract themselves from processing the pictures (DISTRACT). After a break, all pictures were presented again without regulation instruction (re‐exposure). Results revealed that LATER and DISTRACT achieved similar degrees of immediate ROC success, but only LATER had a sustained effect during re‐exposure. In contrast, LPP amplitudes were more prominently reduced during DISTRACT than LATER, and there was no difference in LPP amplitudes during re‐exposure. These findings imply that it may be beneficial to engage with the risks of drug use (reappraisal) rather than avoiding triggers of craving (distraction). However, these effects do not seem to be mediated by lasting changes in cue‐related motivated attention (LPP).
