Abstract
Purpose
Despite the significant increase in the adoption of performance-based contracting (PBC) in various industries, the primary value drivers of it are still not clear. Considering a lack of empirical evidence for PBC, this study investigates the effects of collaboration between the suppliers to understand the value offerings created in PBC by empirical findings. The purpose of this paper is to examine how supply chain collaboration (SCC) affects PBC benefits.
Design/methodology/approach
Using data from 381 survey participants who hold the title of manager or above, hypotheses are tested using structural equation modeling (SEM).
Findings
The results reveal that a strong and positive relationship between SCC and PBC benefits.
Research limitations/implications
One of the limitations of this research is the collection of data through the Amazon Mechanical Turk online service. The experience level of participants in PBC and the absence of validation of these scale items by industrial experts are other limitations of this study. Nonetheless, the authors found convincing evidence that SCC has a positive effect on PBC benefits.
Practical implications
The findings highlight the importance of SCC to increase financial, operational and non-financial benefits of PBC for practitioners. The findings offer guidance for managers aiming to increase PBC benefits through SCC.
Originality/value
This is the first study to empirically examine the impact of SCC for better PBC and contributes to the body of knowledge by providing empirical findings in a PBC context. This research also develops valid and reliable instruments to measure PBC benefits through rigorous empirical and statistical analysis that can be used in future studies.

Abstract
Purpose
The purpose of this study is to determine the factors that impact the trust of microenterprises in online selling platforms and cargo carriers and examine the consequences of a lack of trust.
Design/methodology/approach
This study adopts a qualitative exploratory approach and uses grounded theory to generate insights based on interviews with 27 microenterprise owners selling internationally on an online selling platform.
Findings
The results show that a lack of competence, an absence of an integrated claim system and a lack of transparency are the main factors affecting sellers’ trust in online selling platforms. The relationship between the sellers’ intention to continue to use the online selling platform and their trust in the platform was found to be moderated by switching costs.
Research limitations/implications
This study is limited in that the results were mainly based on the sellers’ perspectives although the phenomenon of interest involves various actors. To mitigate this limitation and cross-check the data, the customer reviews and some of the sellers’ account statistics were also analyzed.
Practical implications
This study introduces the sellers’ perspectives on the dynamics of supply chain management in international micro trade. These dynamics provide a guideline for how to build and manage an online selling platform targeting microenterprises.
Originality/value
Unlike previous studies, this study examines online transaction behaviors from the standpoint of sellers, not buyers. Moreover, it is the first study examining the damaged or lost shipments within the context of online transactions in international micro trade.

Abstract
Purpose
This study aims to empirically test the effects of key characteristics of performance-based contracting (PBC) (i.e. reward/payment scheme, increased supplier autonomy and transfer of responsibilities) on supplier goal commitment.
Design/methodology/approach
This study developed a conceptual model applying goal-setting theory (GST), expectancy theory (ET) and job characteristics theory (JCT). Survey data were collected and analyzed using structural equation modeling (SEM) to establish a validated measurement instrument for testing the hypotheses.
Findings
The findings revealed that PBC positively affects supplier goal commitment due to its unique characteristics, which translates into improved supplier performance. Furthermore, this study validated the mediating role of goal alignment and felt accountability operating between PBC characteristics and supplier goal commitment.
Research limitations/implications
This study explored the buyer–supplier relationship from the supplier's standpoint. Using a more inclusive data set, future research may involve a dyadic analysis and focus on the effects of the following factors on the supplier goal commitment: relational aspects (e.g. trust and collaboration), the risk transfer from the buyer to the supplier, different incentive schemes and successful PBC implementation factors.
Practical implications
This study presents new, validated insights for contract selection, design and management. It underlines the importance of choosing the proper contract, having the appropriate contract design based on the desired outcomes and effective contract management by exhibiting the psychological/behavioral effect of fundamental PBC characteristics.
Originality/value
PBC represents an active research stream, but its psychological/behavioral implications are understudied. Therefore, this research puts forth a conceptual framework with multiple testable hypotheses illustrating the relationship between PBC and supplier goal commitment.

Abstract
Purpose
Performance-based contracting (PBC) has been gaining popularity over the years. However, empirical studies investigating the impact of PBC features have been limited. The main purpose of this study is to investigate the effect of PBC features leading to quality investment that fosters financial benefits.
Design/methodology/approach
After examining the validity and reliability of scale items through confirmatory factor analysis, this study tested hypotheses using covariance-based structural equation modeling of survey data from 381 supply, logistics and operations managers.
Findings
The findings reveal the impact of PBC features (joint knowledge generation, goal congruence and incentive alignment) on financial benefits and the mediation impact of quality investment between these features and financial benefits. The upfront investment for quality enhancement was found facilitator of PBC features to achieve financial benefits. The findings also reveal the importance of collaborative communication and information sharing for knowledge generation that leads financial benefits through quality investment. This study shows that PBC governance strengthens the theory of relational view by empowering collaborative efforts and aligning goals and incentives within downstream suppliers for knowledge generation and quality enhancement.
Research limitations/implications
An analysis of PBC features by industry would be very beneficial in differentiating between and more thoroughly understanding the commonalities and differences across various sectors. Investigating how these change across industries would also help identify any bias in PBC implementation.
Practical implications
This study illustrates that it will be practical and beneficial for suppliers to understand the major drivers of quality investment and the relationship between quality investment and the financial benefits of selecting PBC.
Originality/value
Unlike most previous studies, this research contributes to the literature in that it is one of the relatively few examples of empirical research on PBC features. Overall, the findings of this study will improve our understanding of how PBC features enhance upfront investment in quality and improve financial benefits.

Abstract
Purpose
Global supply chains are increasingly becoming more prone to high-impact disruptions, which has been fairly evident with the coronavirus disease 2019 (COVID-19) pandemic. The capacity to address disruptions is essential for the survival of any organization. Coping with increasing complexity and uncertainties requires a systemic view of supply chains. Furthermore, a comprehensive understanding of the governance structure and timely decision-making are critical in times of disruptions. Although several aspects of supply chain resilience (SCRES) are broadly studied in the literature, the relationship between supply chain orientation (SCO), decentralization in decision-making and SCRES is an understudied area.
Design/methodology/approach
This study takes a longitudinal approach to address this research gap with a comprehensive meta-analytic review to explore the relationships between the constructs of interest through the lenses of contingency and dynamic capability theories. Furthermore, 2 surveys with sample sizes of 250 and 200 were conducted with supply chain professionals to test the research framework before and after the pandemic to compare the findings.
Findings
Structural Equation Modeling (SEM) analysis indicates a positive relationship between SCO and decentralization and between decentralization and SCRES. The post-COVID-19 analysis further validates the influence of agility, collaboration and situational awareness related to decentralization and resilience. More importantly, capabilities have a higher impact on resilience during the pandemic than before.
Practical implications
The results entreat organizations to attain decentralized decision-making vis-à-vis dedicated functional teams charged with reacting timely to disruptions. The teams should be empowered to leverage their knowledge and experiences regardless of their position in the hierarchy.
Originality/value
Although SCRES is an active research stream, the structural aspects of SCRES and its relationship with SCO are understudied. Therefore, this research puts forth a research framework and empirically tests hypotheses that frame the relationship between SCO, decentralization and resilience outcomes in pre- and post-COVID environments.

Abstract
Purpose
In the last 20 years, e-waste has become a serious issue resulting from an overwhelming amount of electronics consumption. However, there has been limited research on how to decrease such waste in a structured manner. Toward study was to use a simulation methodology to investigate the dynamics of upfront investment in reliability enhancement promoted by performance-based contracting (PBC), based on the number of spare parts and duration of the contract.
Design/methodology/approach
The present research first details the relevant mathematical equations and uses game theory to demonstrate the utility for supplier and buyer relationships. Next, the effects of reliability enhancement, spare partsPBC are analyzed using a BlockSim simulation model.
Findings
The results indicate strong relationships among system design cost, reliability, availability and service cost. The authors found that investment in reliability increases system availability while reducing total service costs. Furthermore, increasing the spare parts inventory was determined to have less influence on the readiness of highly reliable systems. The findings support the notion that PBC reduces e-waste by increasing system availability, incentivizing upfront investment in reliability growth.
Research limitations/implications
Recognition of these findings in the context of buyer–supplier relationships will help managers better understand the value of upfront reliability investment, reducing maintenance, repair and overhaul requirements, avoiding the need to plan for extra spare parts and minimizing volume and the resulting e-waste.
Practical implications
This study also clarifies the uncertainty associated with upfront investment and provides potential incentives for suppliers.
Originality/value
The main contribution of this study is its use of PBC for e-waste reduction, highlighting the effects of upfront investment in reliability enhancement. The authors applied a game theory model to illustrate the relationship between incentives and upfront investment and demonstrate how increased levels of spare parts can be counterproductive to achieving readiness, reducing inventory and consequent e-waste.

Abstract
Purpose
The purpose of this study is to determine interfacial convective heat transfer coefficient numerically, for a porous media consisting of square blocks in inline arrangement under mixed convection heat transfer.
Design/methodology/approach
The continuity, momentum and energy equations are solved in dimensionless form for a representative elementary volume of porous media, numerically. The velocity and temperature fields for different values of porosity, Ri and Re numbers are obtained. The study is performed for the range of Ri number from 0.01 to 10, Re number from 100 to 500 and porosity value from 0.51 to 0.96. Based on the obtained results, the value of the interfacial convective heat transfer coefficient is calculated by using volume average method.
Findings
It was found that at low porosities (such as 0.51), the interfacial Nusselt number does not considerably change with Ri and Re numbers. However, for porous media with high Ri number and porosity (such as 10 and 0.51, respectively), secondary flows occur in the middle of the channel between rods improving heat transfer between solid and fluid, considerably. It is shown that the available correlations of interfacial heat transfer coefficient suggested for forced convection can be used for mixed convection for the porous media with low porosity (such as 0.51) or for the flow with low Ri number (such as 0.01).
Originality/value
To the best of the authors’ knowledge, there is no study on determination of interfacial convective heat transfer coefficient for mixed convection in porous media in literature. The present study might be the first study providing an accurate idea on the range of this important parameter, which will be useful particularly for researchers who study on mixed convection heat transfer in porous media, macroscopically.

Abstract
Purpose
This paper aims to identify the personality traits (agreeableness, openness to experience, extraversion, conscientiousness and neuroticism) of library and information science (LIS) students in Pakistan. The difference among the personality traits of LIS students toward their information needs and seeking behavior is also analyzed.
Design/methodology/approach
Two instruments, namely, BFI scale and a self-structured instrument were used to collect the data. Kruskal–Wallis test was applied to find out differences among the personality traits of LIS students toward their information needs and seeking behavior.
Findings
Findings of the study revealed that out of 320 respondents, 186 possessed openness to experience, while only 7 possessed extraversion personality trait. Moreover, the students having extraversion personality trait were, generally, more concerned toward information needs. On the other hand students having conscientious trait were increasingly more seekers of information. Overall, the conscientiousness was identified as the most suitable personality trait for LIS students. A significant difference was also observed among all the personality traits of LIS students.
Practical implications
The findings of this study will help in the identification of LIS individual’s personality. The library managers can use these personality traits for the selection of suitable library professionals for their libraries.
Originality/value
This study can be valuable for the induction of new library professionals and also help managers in assigning the duties based on these personality traits.

The purpose of this paper is to investigate the causes, processes of writer’s block experienced by a group of classroom teacher candidates and its impact on them.
Abstract
Purpose
The purpose of this paper is to investigate the causes, processes of writer’s block experienced by a group of classroom teacher candidates and its impact on them.
Design/methodology/approach
The phenomenological design, which is a qualitative research design, was preferred in the research since it was aimed to investigate the causes, processes of writer’s block experienced by a group of classroom teacher candidates and its effects on the students.
Findings
As a result of the data analysis, it is possible to suggest the limitations of subject and time, problems in the process of writing teaching since primary school, anxiety of being controlled and assessed by grades, fear of being criticized, negativity of classroom settings, lack of information about writing, not being able to read and shortcomings in the vocabulary as the causes of writer’s block.
Research limitations/implications
The research has some limitations. First, the research is only in the phenomenology design. Quantitative research is needed to determine the more common effects of outcomes. The other one is a limitation on the participants. A group of adult teacher candidates constitute the participants of this research. Writer’s block of students at different age levels can be examined longitudinally. Nevertheless, the results of the research have the theoretical implications for teaching writing. It specifically guides to understand and eliminate negative affective factors related to writing.
Practical implications
The results of this research have practical implications in terms of classroom practices. The results of the study show that there are practical implications for what should be considered in classroom writing teaching and to prevent the writer’s block.
Originality/value
Writer’s block is an affective state and the examination of it is important in terms of writing instruction. Many students suffer from writer’s block. However, this subject is neglected by writing researchers and educators. The authors expect the results to guide teachers and writing education researchers. Because of these reasons, this study is important and gives good contribution to literature.

Abstract
Purpose
The purpose of this paper is to identify the factors affecting consumers' online purchase intention and to explore whether there was any significant difference between the path coefficients for males and females.
Design/methodology/approach
Data were collected by distributing questionnaires to 668 Indonesian consumers who were actively using the internet. The data were analyzed using partial least squares structural equation modeling (PLS-SEM) and multi-group analysis (MGA) in SmartPLS 3.0 software.
Findings
Results show that performance expectancy, effort expectancy and personal innovativeness are three influential factors and have a higher path coefficient in both the male and female groups. Anxiety shows a negative and significant relationship with online purchase intention for female consumers than for male consumers. Furthermore, the results of MGA analysis indicate that most factor coefficients in the determinants of online purchase intentions are not significantly different between males and females.
Practical implications
These results help the web retailers to consider the important factors in their strategies when they make strategic decisions as key factors affecting online buying intention. Besides this, the strong relationship between anxiety and intention for females has important implications for managers and designers should pay attention to this factor when designing the content on their business website.
Originality/value
Even though several marketing scholars discuss the factors influencing online shopping behavior, a few studies have shown the role of anxiety and personal innovativeness and their effect on online purchasing that fitted as supplements into the Unified Theory of Acceptance and Use of Technology (UTAUT). In addition, so far, no studies have effectively made a comparative analysis across gender, i.e. are personal and UTAUT factors in the determinants of online purchase intention significantly different across gender?
