Decomposing the effect of supplier development on relationship benefits: The role of relational capital

Buyers invest considerably in developing their suppliers, yet the performance effects of such investments are not universal. Drawing on social capital theory, this research investigates whether the relationship between supplier development and relationship benefits may be facilitated by the generation of relational capital. The authors examine mediating and moderating roles of relational capital in the relationship between two aspects of supplier development (capability development, supplier governance) and two dimensions of relationship benefits (supplier benefits, buyer benefits), using survey data collected from 185 suppliers of a large manufacturing firm. Investment in supplier development does not automatically result in benefits for the supplier or reciprocated benefits for the buyer. Rather, relational capital “bridges” supplier development and relationship benefits. Without relational capital, benefits from capability development do not accrue, and the impact of a supplier governance regime can be even detrimental. In conditions of high relational capital, capability development results in lower perceived buyer benefits. The results can help managers ensure that the benefits from their supplier development efforts fully materialize.     

Take it or leave it: Using regulatory fit theory to understand reward redemption in channel reward programs

Channel Reward Programs (CRPs) facilitate relationship management within reseller networks in distribution channels, yet a persistent problem is that rewards are not seen as valuable, which can reduce program investment. By applying Regulatory Fit theory, to understand how to sustain goal orientation (promotion or prevention) and stimulate task engagement through a match with the manner of goal pursuit, this study demonstrates that the presentation style suppliers adopt influences resellers' perceptions of reward value and their rate of point redemption with respect to CRPs. Two field studies demonstrate the mechanisms driving this effect. First, fit effects result from the interaction between reward type and presentation format (i.e., verbal vs. numerical) and affect perceived reward values and investment decisions. Second, cognitive engagement and “feeling right” about reward redemption mediate the effects of fit on investment opportunity evaluations. In turn, the findings demonstrate that CRP efficacy can be enhanced by stimulating regulatory orientations that match the presentation formats of the reward and that the dual affective–cognitive processes affect probabilistic judgments of rewards. This additional mechanism can further stimulate resellers' engagement with and investment in CRPs within complex decision-making contexts.     

An Extended Neural Network-Based Importance-Performance Analysis for Enhancing Wine Fair Experience

This article presents the results of a study conducted at the Dalmacija Wine Expo, a regional wine fair that was held for the first time in 2010 in Makarska, Croatia. To identify critical attributes impacting the experience of fair participants, two separate surveys were conducted among visitors and exhibitors. In analyzing the data, this study used an extended neural network-based importance-performance analysis (IPA) that combines measures of both the relevance (i.e., stated importance/general importance) and determinance (i.e., derived importance/actual influence) of fair attributes. Compared to traditional IPA approaches with uni-dimensional operationalization of attribute-importance, such an approach provided significantly more detailed (and reliable) managerial implications.     

Managing safety risks in helicopter maritime operations

Nowadays, helicopters have been used in maritime transportation to serve offshore platforms. This paper outlines methodology for assessing safety risks by operating in the vicinity of helidecks. During each flight, decisions must be made regarding the events that involve interactions between the four safety risk elements – the pilot in command, the aircraft, the environment and the operation. This paper evaluates helicopter crash statistics based on region and flight phase. Data collected were used for developing methodology for computing the helicopter impact frequency into facility of interest. The analysis for helicopter impact frequency calculations is based on number of operations, crash rate, frequency, average length of flight and crash area. Furthermore, the conclusion was defined based on future measurements for helicopter accidents mitigation or reduction. The presented paper contributes to safety risk assessment in helicopter maritime operations.     

Mobility,risk tolerance and competence to manage risks

Migration is a risky behaviour because of the uncertainty about future wages, living conditions, changing relationships with family and friends and cultural adjustment. While there has been some research on risk and uncertainty in migration, this has mostly been approached as a form of ‘rational’ decision-making: such approaches explain why some groups of individuals are more likely than others to migrate, but are limited in explaining individual variations in behaviour within these groups. Individual migrants vs. non-migrants are self-selected in terms of tolerance of risk and uncertainty but, with very few exceptions, there has been no research on migration within the framework of risk tolerance/aversion and competence to manage risk. Moreover, existing research is based on, and constrained by the limitations of, incumbent data-sets. Drawing on a specially commissioned large-scale survey of the UK population, this paper uses principal component analysis and logistic regression to analyse the extent to which risk and risk-related measures can be used to predict four different types of mobility profiles. There are significant associations between these individual mobility characteristics and general risk/uncertainty tolerance, and competence-based tolerance. These are strongest in terms of the two most polarised mobility types: the least mobile, the Stayers, and the most mobile, the Roamers. Recognising that previous migration is exogenous, a further analysis of migration intentions, with previous migration included as an independent variable, finds the propensity for future migration is, in fact, negatively associated with previous migration, probably due to the importance of ‘pure risk’ as opposed to acquired competence via migration experience, and to life cycle considerations.     

An Empirical Investigation of Brand Equity: A Cross-Country Validation Analysis

ABSTRACT

The purpose of this article is to propose and test a model in order to better understand brand equity. The goal of this research is to identify the drivers and determine how they influence brand equity performance in the researched industry in order to develop a more effective brand strategy. Quantitative data collected are used to test a model of brand value in the context of the food industry. The findings of this research provided evidence that the customer-based brand equity model can be applied to the food industry context and be used to guide marketing activities internationally. Brand awareness has a positive influence on brand associations and perceived quality. Brand associations have a positive influence on brand loyalty. Finally, brand loyalty, perceived quality, and brand associations all have a positive effect on brand equity. This study contributes to the scarce international brand equity literature by testing the proposed model using data from a sample of consumers in two European countries.     

Conceptual and mathematical model for quality improvement in health care

Numerous studies have shown that implemented models for quality assurance or improvement in healthcare facilities differ, even those models that are based on the same guidelines, i.e. standards, regulations or concepts. The cause of diversity in implemented quality models could be found in the process of translating guidelines into the implemented model for quality assurance or improvements in healthcare facilities, while neglecting processes of healthcare facilities that are not clinical processes, but still responsible for the quality of healthcare services. Therefore, this research recommends a conceptual model that should be a link between guidelines, implemented models and mathematical models derived from the conceptual model, which could provide a means of evaluating quality values of any part of the healthcare organization.

Posting,quoting, and replying: a comparison of methodological approaches to measure communication ties in web forums

Active involvement in discussion-based communities is nowadays a firm part of people’s online activities. The measurement of communication ties and networks between contributors to such domains is thus becoming a relevant research question in social sciences. However, especially in web forums, very often almost no direct relational information exists that would indicate the presence of communication ties among contributors. In contrast with the reply-to structure of Usenet newsgroup or mailing list conversations that contain explicit relational information created by the contributors, some web forums only enable participants to add new posts to threads or to quote preceding posts in threads. When discussions emerge, it is difficult to identify who is replying to whom. Drawing on the social network studies dealing with the conversational patterns in Usenet and web forums, this paper presents an alternative approach to identifying the ties between authors of posts. Several assumptions are discussed, and different measures are developed and empirically evaluated. The findings provide a starting point for the development of a standardized methodology for studying social networks in online communities where only limited direct information about communication ties is available.     

A new non-linear AR(1) time series model having approximate beta marginals

We consider the mixed AR(1) time series model $$X_t=\left\{\begin{array}{ll}\alpha X_{t-1}+ \xi_t \quad {\rm w.p.} \qquad \frac{\alpha^p}{\alpha^p-\beta ^p},\\ \beta X_{t-1} + \xi_{t} \quad {\rm w.p.} \quad -\frac{\beta^p}{\alpha^p-\beta ^p} \end{array}\right.$$ for ?1 < β ^p ≤ 0 ≤ α ^p  < 1 and α ^p ? β ^p  > 0 when X _t has the two-parameter beta distribution B₂(p, q) with parameters q > 1 and ${p \in \mathcal P(u,v)}$ , where $$\mathcal P(u,v) = \left\{u/v : u < v,\,u,v\,{\rm odd\,positive\,integers} \right\}.$$ Special attention is given to the case p = 1. Using Laplace transform and suitable approximation procedures, we prove that the distribution of innovation sequence for p = 1 can be approximated by the uniform discrete distribution and that for ${p \in \mathcal P(u,v)}$ can be approximated by a continuous distribution. We also consider estimation issues of the model.
