Abstract
Purpose
The purpose of this qualitative study is to explore how highly educated women respond to career chance events in a Korean context where traditional cultural values and male-dominated organizational culture coexist.
Design/methodology/approach
The authors conducted 50 semi-structured interviews with highly educated women operationalized as women with doctoral degrees in and out of Korea. The authors used a collaborative research process with a team of ten Korean-born researchers who have built consensus on research themes through discussions on the collection and analysis of a large data set, thus reducing the researcher bias issue inherent in qualitative research.
Findings
In an analysis of the interview data collected, the authors report on three themes: before obtaining a doctoral degree, during and after their doctoral study and responses (coping strategies) to chance events in their careers. Highly educated women’s pursuing a doctoral degree was a way to maintain work–life balance in Korea where women are expected to take a primary caregiver role. After obtaining a doctoral degree, participants struggled with limited job opportunities in the male-dominated higher education. Women’s unplanned and unexpected chance events are intertwined with the male-dominated culture in Korea, and career interruptions as such a chance event, whether voluntary or involuntary, happened largely due to family reasons. In this context, highly educated women responded to chance events largely at individual and family levels and articulated the need for support at organizational and government levels.
Research limitations/implications
The study findings confirm the literature that women’s careers are limited by traditional family roles in non-Western countries where strong patriarchal culture is prevalent. Particularly, women’s career interruptions surfaced as a critical chance event that either disrupts or delays their careers largely because of family issues. Future research is called for to identify both individual and contextual factors that influence women’s decisions on voluntary and involuntary career interruptions as their responses to chance events.
Practical implications
Based on highly educated women’s coping strategies largely at individual and family levels, we suggest national human resource development policies put in place not to lose out on the opportunity to develop highly educated women with doctoral degrees as a quality workforce for a nation’s sustainable economic growth. Additionally, organizations need to be aligned with the government policies and programs for the provision of developmental programs for women in the workplace, beginning with highly educated women’s career planning, while creating organizational culture to promote gender equality as a long-term goal.
Originality/value
The participants’ voluntary career breaks helped them care for their children, be involved in their children’s education, reflect on work–life balance after having long hours of work for many years and move forward with personal satisfaction. Voluntary career breaks can be understood as highly educated women’s unique way of responding to chance events.

Abstract
Purpose
Extant studies on the relational capital—performance benefits in buyer–supplier relationships (BSRs) give limited attention to the value of internal resources/capabilities possessed by each party, thus imply the universal benefits of relational capital regardless of a party's own abilities. To fill this gap in the literature, this paper aims to investigate whether and how a firm's operational efficiency moderates the relation between its relational ties with the largest customer and its performance outcomes.
Design/methodology/approach
This study employs a large panel data of US public firms and their major customer relationships for the period of 1980–2018 from Compustat and a two-stage least square regression to address endogeneity concerns.
Findings
The authors find that suppliers achieve different performance benefits and disbenefits from their relational ties with major customers depending on their own operational efficiency. Specifically, strong suppliers achieve higher market share and lower profitability as relational ties with major customers increase. In contrast, weak suppliers who develop high levels of relational ties with their major customers tend to increase their profit-generating potential, yet their market share declines. Thus, the findings suggest that suppliers make different trade-offs between profit enhancement and pie expansion depending on their operational efficiency.
Research limitations/implications
As a secondary data study, this research relies on proxy measures to capture relational ties in BSRs. Although the validity of the proxy measures are well established in the literature, additional primary information on sample firms and their relationships may be able to identify other types of internal and external resources and capabilities that can be leveraged as relational capital.
Practical implications
Relational ties with major customers entail both relational capital and relational liabilities. Strong suppliers trade off their profit-maximizing potential for the pie expansion opportunity via sales growth to major customers. On the other hand, weak suppliers achieve higher profits from relational ties with major customers, but this benefit comes at the expense of pie expansion due to decreasing sales to major customers. Managers should be aware of performance trade-offs between profit enhancement and pie expansion depending on a firm's internal capabilities and carefully choose to develop and exploit relationship-based assets with customers depending on their performance goals.
Originality/value
The contrasting performance outcomes demonstrated by strong and weak suppliers in this study challenge the prevailing assumption about the broad performance benefits of relational ties in BSRs. To the best of the authors’ knowledge, this research is the first to empirically substantiate the contingency role of suppliers' operational efficiency in the relational capital—performance link.

Abstract
Purpose
Extant research documents the cost benefits of group purchasing organizations (GPOs) to member hospitals, but understudies concerns about the market dominance of a few large GPOs and the relatively weakened buyer power of hospitals in the US healthcare product supply chain. To fill the gap in the literature, this study investigates whether GPO size and a hospital’s relative power to its GPO affect the hospital’s supply expenses, and whether and how system membership moderates the power–performance link.
Design/methodology/approach
For this study, we collect the panel data from various secondary sources on GPO–hospital dyads, which include the seven largest GPOs and their 2,590 unique acute care hospital members in 51 states over the period of 2009–2017. To address the endogeneity issue associated with simultaneity, we establish a one-year time lag between dependent and independent variables and analyzed the 15,527 hospital-year observations using the time-series regression with fixed-effect.
Findings
We find that a hospital’s relative power to its GPO is the most critical factor to reduce its supply cost while GPO size has no effects. We also find that a nonsystem hospital achieves greater cost savings by leveraging its relative power to its GPO while a system hospital gains no benefits.
Originality/value
To the best of our knowledge, this study is the first to address the paradox of GPO size and a hospital’s relative power and the moderating role of system membership for the hospital’s purchasing efficiency using a large nation-wide dataset of US hospitals–GPO dyads.

Abstract
This paper employs the concept of supply chain orientation in container port management and empirically tests whether the measurement models proposed in some notable previous research have universal application. In addition, this study attempts to identify any significant causal relationships between port supply chain orientation and port performance from the view point of shipping companies. In the current study port supply chain orientation was found to have limited effect on customer satisfaction and port competitiveness, which might has been caused by some implemental and practical issues. However, the present study reveals the potential importance of port supply chain management by empirically demonstrating that “closer relationship with shipping lines” and “innovative value added service” could function as critical components for container ports/terminals to improve customer satisfaction and enhance their competitiveness.

Abstract
Purpose
The purpose of this paper is to examine the structural relationships among lifestyle of health and sustainability (LOHAS), healthy food choices, trust, and emotional loyalty and the moderating role of age between seniors and non‐seniors in restaurants.
Design/methodology/approach
Partial least squares (PLS)‐graph software (version 3.0) was used to analyze the measurements and structural models. The authors employed a PLS regression analysis for both the formative and reflective constructs in the empirical test of the research model.
Findings
The study revealed that the senior market segment differs from the non‐senior market segment in the following ways: the magnitude of impact of LOHAS on healthy food choices is much stronger for senior diners than for non‐senior diners and the impact of LOHAS on trust and emotional loyalty is greater for seniors than non‐seniors.
Research limitations/implications
The results of this study can guide the restaurant industry in its research on the implications of LOHAS for seniors.
Practical implications
Restaurant marketers should develop different strategies for the senior and non‐senior market segments, and they need to focus on target segments rather than attempting to appeal to the market as a whole.
Originality/value
This paper assists researchers and practitioners by shedding light on the differences among LOHAS, healthy food choices, trust, and emotional loyalty between senior and non‐senior diners.

Abstract
Purpose
The purpose of this paper is to examine the efficacy of microbial elimination using different sanitizers in raw vegetables (cherry tomatoes, spring onions, Chinese chives, and chicory) and to analyze the efficacy of Escherichia coli O157:H7 reduction by type of sanitizer and vegetable.
Design/methodology/approach
To assess the sanitizing effects of microbial elimination by variety of vegetable, the samples were grouped into four different washing methods: control (no sanitizer), 100 ppm chlorine, 100 ppm electrolyzed water, and 200 ppm electrolyzed water after prewashing. Subsequently, quantitative microbiological experiments were conducted to assess aerobic mesophilic plate count (APC), coliform, E. coli, and Bacillus cereus, and sensory changes of the sanitized vegetables were tested. Thereafter, measurement of the sanitizing effects on bacterial reduction after inoculation with E. coli O157:H7 was conducted.
Findings
The microbial levels of four types of vegetables ranged from 3.37 to 5.24 log CFU/g for APC, 2.41 to 5.57 log CFU/g for E. coli, 0.25 to 5.40 log CFU/g for coliform, and 0.83 to 5.44 log CFU/g for B. cereus. After three types of sanitizing treatments, microbial reduction effects showed 0.94-1.84 log CFU/g for APC, 0.56-1.00 log CFU/g for E. coli, 0.18-1.26 log CFU/g for coliform, and 0.56-1.23 log CFU/g for B. cereus (p<0.05). In sensory evaluation, there were no significant differences in taste and flavor between with and without sanitizing treatments. Regarding bacterial reduction after inoculation with E. coli O157:H7, the microbial reduction on vegetables was shown to be in the range of 0.27-1.57 log CFU/g with 100 ppm sodium hypochlorite, 0.66-3.07 log CFU/g with 100 ppm electrolyzed water, and 0.79-2.55 log CFU/g with 200 ppm electrolyzed water. Chicory, cherry tomato, and spring onion showed significant reduction levels of E. coli O157:H7 after sanitation (p<0.05).
Originality/value
This study revealed that different sanitization methods are required for different types of vegetables. Electrolyzed water treatment (100 ppm) is a more effective and safe method of washing raw vegetables. Given that the main purpose of sanitizing fresh-cut produce is to maximally reduce microorganism levels, different methods of sanitizing fresh-cut produce with an adequate washing method should be used according to vegetable type.

This study aims to investigate the factors influencing the data sharing habits of psychologists with respect to academic reciprocity.
Abstract
Purpose
This study aims to investigate the factors influencing the data sharing habits of psychologists with respect to academic reciprocity.
Design/methodology/approach
A research model was developed based on Ostrom’s (2003) theory of collective action to map psychologists’ underlying motivations for data sharing. The model was validated by data from a survey of 427 psychologists, primarily from the psychological sciences and related disciplines.
Findings
This study found that data sharing among psychologists is driven primarily by their perceptions of community benefits, academic reciprocity and the norms of data sharing. This study also found that academic reciprocity is significantly influenced by psychologists’ perceptions of community benefits, academic reputation and the norms of data sharing. Both academic reputation and academic reciprocity are affected by psychologists’ prior experiences with data reuse. Additionally, psychologists’ perceptions of community benefits and the norms of data sharing are significantly affected by the perception of their academic reputation.
Research limitations/implications
This study suggests that Ostrom’s (2003) theory of collective action can provide a new theoretical lens in understanding psychologists’ data sharing behaviours.
Practical implications
This study suggests several practical implications for the design and promotion of data sharing in the research community of psychology.
Originality/value
To the best of the authors’ knowledge, this is one of the initial studies that applied the theory of collective action to the mechanisms of reputation, community benefits, norms and reciprocity in psychologists’ data sharing behaviour. This research demonstrates that perceived community benefits, academic reputation and the norms of data sharing can all encourage academic reciprocity, and psychologists’ perceptions of community benefits, academic reciprocity and data sharing norms all facilitate their data sharing intentions.

Abstract
Purpose
This paper aims to examine the mediating roles of self-efficacy and team commitment in linking service employees’ relative leader-member exchange (RLMX) with customer service behaviors and also the moderating roles of team-level differentiations in leader-member exchange (LMX) and team-member exchange (TMX) in influencing these mediation processes.
Design/methodology/approach
Data were collected from 467 customer-contact employees working in hotel restaurants. Hierarchical linear modeling analysis was used to test the mediation hypotheses, and moderated path was used to assess the moderated mediation.
Findings
Self-efficacy and team-commitment both mediated the relationship between RLMX and customer service behaviors. The differentiations in LMX and TMX significantly interacted with RLMX in predicting self-efficacy and team commitment and also moderated the indirect effects of RLMX on customer service behaviors.
Research limitations/implications
Future studies need to incorporate customers’ or immediate supervisors’ ratings of subordinates’ customer service behaviors and replicate the findings in different countries and work settings.
Practical implications
Hospitality managers should foster a work environment wherein they develop equal quality relationships with their subordinates in a workgroup and promote high-quality relationships among subordinates in the workgroup to improve subordinates’ self-efficacy, team commitment and, subsequently, their customer service behaviors.
Originality/value
This study incorporates both self-efficacy and team commitment as motivation-based and social exchange-based mediators, respectively, in predicting customer service behavior. It also extends the boundary condition for the mediations by considering the team-level differentiations in both vertical exchange (LMX) and horizontal exchange (TMX).

Abstract
Purpose
This study aims to propose and validate a model for e-Learning success based on students’ experiences in the “new normal.” To achieve this goal, this study focused on answering three research questions: (1) What are the students’ experiential factors that impact e-Learning? (2) How do these experiential factors affect e-Learning success? (3) In what ways does a multimethod provide a comprehensive perspective and an in-depth understanding of students’ e-Learning experiences in the new normal?
Design/methodology/approach
This study applied a mixed-methods sequential approach using exploratory, confirmatory and complementary studies. First, this study undertook a text-mining exploratory analysis of the review data to extract e-Learning topics. Then, based on the Information Systems (IS) success model, this study identified an integrated framework drawn from the results of the text-mining analysis. Second, this study proposed an e-Learning, experience-based success model and corresponding hypotheses and conducted a confirmatory study with surveys to validate the model. Third, this study conducted in-depth interviews to better identify the phenomenon of interest.
Findings
The five factors extracted from the first stage are system quality, lecture content, teaching quality, online interaction and achievement. This study subsequently confirmed the significant relationships between the e-Learning success factors in the second stage based on the IS success model. Finally, a complementary study identified the importance of interactivity for e-Learning success in the new normal.
Originality/value
To the best of the authors’ knowledge, this paper is the first to develop an e-Learning success model using a comprehensive mixed-methods approach.
