SUMMARY Trust is a critical factor fostering commitment among supply chain partners. The presence of trust improves measurably the chance of successful supply chain performance. A lack of trust among supply chain partners often results in inefficient and ineffective performance as the transaction costs (verification, inspections and certifications of their trading partners) mount. Although the literature often mentions a relationship between trust and commitment, there is a lack of empirical testing of such relationship in the supply context. This study attempts to fill the gap between the theoretical argument and empirical testing. Results using a comprehensive survey of supply chain practitioners indicate that a firm's trust in its supply chain partner is highly associated with both sides' specific asset investments (positively) and behavioral uncertainty (negatively). It is also found that information sharing reduces the level of behavioral uncertainty, which, in turn, improves the level of trust. A partner's reputation in the market has a strong positive impact on the trust‐building process, whereas a partner's perceived conflict creates a strong negative impact on trust. Finally, the level of commitment is strongly related to the level of trust. Policy implications are discussed.
Entry mode choice is a critical ingredient of international entry strategies, and has been voluminously examined in the field. The findings, however, are very mixed, especially with respect to transaction-cost-related factors in determining the ownership-based entry mode choice. This study conducted a meta-analysis to quantitatively summarize the literature and empirically generalize more conclusive findings. Based on the 106 effect sizes of 38 empirical studies, the meta-analysis shows that the findings of the existing studies are moderated to varying degrees by both study-setting factors and statistical artifacts, although the combined overall effects of transaction cost-based determinants are consistent with the predictions of transaction cost economics. We extensively discuss the implications of meta-analytical results, especially moderating effects of location, country of origin, industry type, and statistical artifacts, highlight the measurement adequacy, equivalence, and multidimensionality of transaction cost determinants, and present our suggestions to improve theoretical inquiries and empirical verifications on entry mode choice.

Purpose -The primary purpose of this study is to examine the relationships between the level of trust and several relevant constructs drawn from transaction cost analysis (such as asset specificity, behavioral uncertainty, and partner's opportunism) and social exchange theory (informational sharing). Design/methodology/approach -A comprehensive questionnaire based on various theories on trust and commitment was mailed in 2001 to supply chain practitioners in the Midwest region. A total of 171 valid returns were received out of 1,800 mailings (9.5 percent). A path analysis was used to estimate parameters or relationship between relevant constructs and trust, and trust with the level of commitment. Findings -A firm's trust in their supply chain partner is highly associated with both parties' specific asset investments and social exchange theory. Information sharing has a primary impact on reducing (improving a partner's uncertainty behavior which, in turn, would improve the level of trust. Finally, the level of commitment is strongly related to the level of trust, supporting Morgan and Hunt's hypothesis.Research limitations/implications -This research used supply chain practitioners in one region as a target population. It is highly recommended to duplicate this study in other regions to verify the findings. Originality/value -This is the first research paper linking various variables to trust and trust to commitment in supply chain management using path model.
The toughening effects of graphene and graphene‐derived materials on thermosetting epoxies are investigated. Graphene materials with various structures and surface functional groups are incorporated into an epoxy resin by in situ polymerization. Graphene oxide (GO) and GO modified with amine‐terminated poly(butadiene‐acrylonitrile) (ATBN) are chosen to improve the dispersion of graphene nanosheets in epoxy and increase their interfacial adhesion. An impressive toughening effect is observed with less than 0.1 wt% graphene. A maximum in toughness at loadings as small as 0.02 wt% or 0.04 wt% is observed for all four types of graphene studied. An epoxy nanocomposite with ATBN‐modified GO shows a 1.5‐fold improvement in fracture toughness and a corresponding 2.4‐fold improvement in fracture energy at 0.04 wt% of graphene loading. At such low loadings, these graphene‐type materials become economically feasible components of nanocomposites. A microcrack mechanism is proposed based on microscopy of the fracture surfaces. Due to the stress concentration by graphene nanosheets, microcracks may be formed to absorb the fracture energy. However, above a certain graphene concentration, the coalescence of microcracks appears to facilitate crack propagation, lowering the fracture toughness. Crack deflection and pinning likely contribute to the slow increase in fracture toughness at higher loadings.
This study attempted to empirically test a debatable hypothesis that globalization entails homogenization in consumers’ mind and behavior. Using samples from two countries (USA, n = 120 and Korea, n= 128), this study explored a path model centered on consumers’ reluctance to purchase foreign goods. The findings indicated that, in the US sample only, consumer ethnocentrism plays a mediating role between global openness and the reluctance to buy, although it is on the decrease with the increasing level of global openness. Consumer ethnocentrism is still an important factor in determining the magnitude of reluctance to buy a foreign product in both samples, while product judgment also plays an important role, but only in a certain cultural context (i.e. the USA). It is concluded, therefore, that consumers in a different culture, who are different in their attitudes and perceptions, tastes and preferences, and values, are still different even after being exposed to the massive wave of globalization.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
