Structural equation modeling (SEM) is a powerful multivariate statistical technique that requires careful application. The use of SEM in international business research has substantially increased recently, necessitating a critical evaluation of its use in the field. Through an analysis of 148 articles in the international business (IB) literature, we detail the state of current use of SEM in IB research and compare its use to the established best practices. In many instances, SEM's use in IB has been faulty, suggesting that authors may have drawn incorrect conclusions. To expand the IB field's knowledge base, methodological accuracy is essential. Based on our review of the technique's use in IB research coupled with the established practices in the social science literature, we provide practical suggestions for better applying SEM in the IB literature.

This study examines customers of grocers who provide both online and traditional in‐store options to determine if there are substantial differences in customer's perceptions of service quality, product quality, product range, and sacrifices made when using a specific channel. By better understanding customer preferences, firms can appropriately match strategy and market expectations.

Data were gathered from 271 traditional in‐store customers and 1,720 online customers from three grocers. Survey results from these two groups was analyzed using regression analysis consisting of independent variables measuring the sacrifices of using a given channel, and the quality of service, products and product range and dependent variables of behavioral intentions and percent of business given to the grocer.

Online customers have a higher level of satisfaction with their service encounters, but lower levels with the tangible aspects of product quality, range of products available and channel usage sacrifices. They also spend a larger portion of their grocery “wallet” with the grocer and are less price sensitive than their in‐store counterparts.

Online customers place a premium on convenience and will spend more with firms that meet this need. Given the very low profit margins in this industry, the ability to draw and retain these customers is vitally important.

This study presents one of the first direct comparisons of customers who use two different channels from the same grocery provider to examine customer perceptions for improved strategic service and product delivery.

The purpose of this paper is twofold: to identify, evaluate and structure the research that focusses on omni-channel retailing from the perspective of logistics and supply chain management; and to reveal the intellectual foundation of omni-channel retailing research.

The paper applies a multi-method approach by conducting a content-analysis-based literature review of 70 academic papers. Based on the reference lists of these papers, the authors performed a citation and co-citation analysis based on the 34 most frequently cited papers. This analysis included multidimensional scaling, a cluster analysis and factor analysis.

The study reveals the limited consideration of logistics and supply chain management literature in the foundation of the omni-channel retailing research. Further, the authors see a dominance of empirical research as compared to conceptual and analytical research. Overall, there is a focus on the Western retail context in this research field. The intellectual foundation is embedded in the marketing discipline and can be characterised as lacking a robust theoretical foundation.

The contribution of this research is identifying, evaluating and structuring the literature of omni-channel research and providing an overview of the state of the art of this research area considering its interdisciplinary nature. This paper thus supports researchers looking to holistically comprehend, prioritise and use the underpinning literature central to the phenomena of omni-channel retailing. For practitioners and academics alike, the findings can trigger and support future research and an evolving understanding of omni-channel retailing.

The purpose of this paper is to investigate how grocery retailers configure their online fulfilment centres (OFC) as they move towards an omni-channel structure and what contextual factors influence their decisions.

An exploratory case study with three grocery retailers in the Nordic countries was conducted. The study investigates the current OFC configurations and identifies nine important contextual factors.

This study shows the importance of understanding the changes that omni-channel retailing entails for an OFC configuration. Nine contextual factors were identified. Several of the factors are found in previous theory, but this paper extends the knowledge of how they affect the configuration of an OFC in grocery retail. The changes in, for example, order characteristics create different requirements for picking, packing, sorting and shipping when compared with traditional distribution centres (DC). Although representing a separate flow for online fulfilment, OFC configuration depends on how the other logistics flows from the DC to stores are designed.

To support further theory development, nine contextual factors and their relationship to OFC configurations are proposed.

This study provides managerial value in two ways. First, grocery retailers with one or more OFCs can benchmark existing solutions using the empirical case descriptions. Second, the findings provide grocery retailers with knowledge of how to configure an OFC.

The literature lacks a holistic approach towards how grocery retailers configure their OFCs and what factors affect these decisions. This study provides the first in-depth analysis of how the omni-channel context affects the configuration of all the aspects of an OFC.

The development and testing of the hedonic methods for property valuation require statistical analysis and professional preparation of relevant databases. As a first step, the presumable relevant influencing variables (parameters) have to be determined. Previous studies have shown a large variety of parameters which overlap or deviate from each other. This study aims to collect, systematise and structure different parameters for the further development and testing of hedonic models.

The study comprises a detailed research and deeper analysis of previous studies regarding the hedonic valuation (mainly for residential properties). Flanking areas of examination serve, if they are appropriately suitable, as supplements (e.g. performance analysis and regression). Parameters are extracted from a wide range of literature, compared and integrated into an overall presentation of the results.

In total, 407 parameters were extracted from previous studies on hedonic valuation and performance analysis. Because of various definitions of some parameters in the literature, the current paper combined them in one meaning to avoid misunderstandings in further analysis. Higher-level (global) and lower-level (specific) parameters are contained/described in the final list. The result of this study identifies up to five levels of parameters (within the relevant hierarchy).

The parameters have not yet been statistically tested. The relevance of individual parameters has to be tested with relevant corresponding databases and statistical methods (e.g. correlation and regression).

To manage larger real estate portfolios, there is a need for regular property valuations. From this perspective, there is a great interest related to the optimisation of the valuation costs, valuation quality and valuation duration. Hedonic methods are considered as an efficient way of performing these valuation tasks. However, further suitable models and parameters are needed. The study describes parameters that can be appropriate for the development of relevant models and creates a structured parameters list, providing the technical basis for the latter. This structured parameter list is substantiated by the evaluation of the existing research.

Property values represent a significant asset for the national economy and for the individual wealth/welfare. The development of property value in a national economy is also relevant for politics, economy and society. The use of hedonic methods and the knowledge of important individual parameters can contribute towards assessing and substantiating the effect of political decisions on the value of real estate.

For the first time, a comprehensive and structured analysis on the value of the relevant parameters used in hedonic methods is performed. Thereby a large number of parameters were identified which question the stability of the results in respective individual studies. In addition, the newly developed hierarchy of parameters can serve as the basis for further research.

The purpose of this paper is to compare competing adaptive strategies for fast frequency sweeps for driven and waveguide‐mode problems and give recommendations for practical implementations.

The paper first summarizes the theory of adaptive strategies for multi‐point (MP) sweeps and then evaluates the efficiency of such methods by means of numerical examples.

The authors' numerical tests give clear evidence for exponential convergence. In the driven case, highly resonant structures lead to pronounced pre‐asymptotic regions, followed by almost immediate convergence. Bisection and greedy point‐placement methods behave similarly. Incremental indicators are trivial to implement and perform similarly well as residual‐based methods.

While the underlying reduction methods can be extended to any kind of affine parameter‐dependence, the numerical tests of this paper are for polynomial parameter‐dependence only.

The present paper describes self‐adaptive point‐placement methods and termination criteria to make MP frequency sweeps more efficient and fully automatic.

The paper provides a self‐adaptive strategy that is efficient and easy to implement. Moreover, it demonstrates that exponential convergence rates can be reached in practice.
