The purpose of this paper is to conduct a critical review of the mediation studies published in the field of Human Resource Development (HRD) to discern if the study designs, the nature of data collection and the choice of statistical methods justify the causal claims made in those studies.

This paper conducts a critical review of published refereed articles that examined mediation in Human Resource Development Quarterly, Human Resource Development International, Advances in Developing Human Resources and European Journal of Training and Development. Mediation studies published in these journals from 2000 to 2015 were identified and coded. The four journals sampled were chosen to provide breadth of coverage of the different types of empirical studies published in the field of HRD.

The review findings imply that HRD scholars are not employing experimental or longitudinal designs in their studies when randomized experiments and longitudinal studies with at least three waves of data collection are regarded as the golden standards of causal research. Further, the findings indicate that sophisticated statistical modeling approaches like structural equation modeling are widely used to examine mediation in cross-sectional studies and most importantly, a large number of such studies do not acknowledge that cross-sectional data does not allow definite causal claims.

Although the findings urge us to rethink the inferences of mediation effects reported over the past 15 years in the field of HRD, this study also serves as a guide in thinking about framing and testing causal mediation models in future HRD research and even argues for a paradigm shift from a positivist orientation to critical and postmodern perspectives that can accommodate mixed methods designs for mediation research in HRD.

This paper presents a critical review of the trends in examining mediation models in the HRD discipline, suggests best practices for researchers examining the causal process of mediation and directs readers to recent methodological articles that have discussed causal issues in mediation studies.

This study aims to understand the impact of underlying theme in the communication on social media on funding received by early-stage start-ups.

The study is based on empirical testing of data of 849 start-ups and more than 130K tweets. Machine learning (ML) model has been used for text classification of 130K+ tweets. Causal mediation analysis with bootstrapping is carried out for hypothesis testing.

Tweets addressing quality-related uncertainty are a predictor of amount of funds raised. Audience response acts as a mediator between tweets focusing on relational orientation and amount of funds raised.

The authors advance signaling theory by theorizing and investigating the importance of signal content. Endogenous signal of quality directly influences the start-ups outcomes, while exogenous signal helps disseminate information and influence the success.

Entrepreneurs should put in concerted effort to reduce uncertainty about the start-ups. Value creation is a central concept for start-ups; however, communicating value should be the dominant part of social media strategy.

Computer-based language processing techniques have amplified the research focused on content. To the best of the authors’ knowledge, this is the first comprehensive study that explores underlying themes of communication of start-ups and their impact on acquiring funds.

Although phone calls are widely used by debt collection services to persuade delinquent customers to repay, few financial services studies have analyzed the unstructured voice and text data to investigate how debt collection call strategies drive customers to repay. Moreover, extant research opens the “black box” mainly through psychological theories without hard behavioral data of customers. The purpose of our study is to address this research gap.

The authors randomly sampled 3,204 debt collection calls from a large consumer finance company in East Asia. To rule out alternative explanations for the findings, such as consumers' previous experience of being persuaded by debt collectors or repeated calls, the authors selected calls made to delinquent customers who had not been delinquent before and were being called by the company for the first time. The authors transformed the unstructured voice and textual data into structured data through automatic speech recognition (ASR), voice mining, natural language processing (NLP) and machine learning analyses.

The findings revealed that (1) both moral appeal (carrot) and social warning (stick) strategies decrease repayment time because they arouse mainly happy emotion and fear emotion, respectively; (2) the legal warning (stick) strategy backfires because of decreasing the happy emotion and triggering the anger emotion, which impedes customers' compliance; and (3) in contrast to traditional wisdom, the combination of carrot and stick fails to decrease the repayment time.

The findings provide a valuable and systematic understanding of the effect of carrot strategies, stick strategies and the combinations of them on repayment time. This study is among the first to empirically analyze the effectiveness of carrot strategies, stick strategies and their joint strategies on repayment time through unstructured vocal and textual data analysis. What's more, the previous studies open the “black box” through psychological mechanism. The authors firstly elucidate a behavioral mechanism for why consumers behave differently under varying debt collection strategies by utilizing ASR, NLP and vocal emotion analyses.

This study aims to provide a better understanding of how gift card receivers react to the types of gift cards. This study examined the effect of gift card types (intangible experiences vs less intangible experience vs tangible goods) on a recipient’s willingness to spend more through emotions and perceived effort (Study 1) and on feeling of appreciation (Study 2).

Study 1 adopted a scenario-based 2 (tangible vs intangible) × 3 ($100 vs $200 vs $300) between-subjects design. Study 2 narrowed the scope of gift card type (intangible vs less intangible).

Receivers tended to perceive less effort in gift card selection and feel less emotion when receiving gift cards for intangible experiences than when receiving gift cards for both tangible and less intangible products. However, as face value increased, gift card receivers for intangible experiences felt more pleasure and, in turn, rated higher willingness to spend more money than face value than those with gift cards for tangible products.

Future studies can rule out alternative explanations related to brand-related effects, previous experiences and personal preferences.

Service providers should put more effort into tangibilizing the intangibles to reduce receivers’ uncertainty. Also, they can increase their profitability by stimulating gift card receivers’ willingness to spend more money through pleasure.

Answering research calls for examining consumers’ perceptions of different gift card types, this study might be the first to unveil the differential effect of gift card types associated with the tangibility of products on purchase behavior and the underlying emotional mechanism.

This study investigates the situations in which productive organizational energy (POE) and organizational performance increase through customer passion, that is, perceived customers’ affective commitment and customers’ positive word-of-mouth behavior. We integrate research on POE with research on customer influences on employees. Based on emotional contagion processes we develop hypotheses for the energizing influences of customers at the organizational level. We test the hypotheses using a dataset containing 495 board members and 8,299 employees of 152 organizations. The results show that customer passion is positively related to POE, which is in turn positively related to organizational performance. Furthermore, the findings indicate that the effect of customer passion on organizational performance through POE depends on top management team’s (TMT’s) customer orientation. By providing first insights into the linkages and contingencies of customer passion, POE, and organizational performance, this study puts forth a more holistic understanding of the energizing effect of customers on organizations.

Mediating effects are often tested using hierarchical multiple regression (HMR) procedures. Typical of the HMR-based strategies is the very frequently cited and widely used procedure described by Baron and Kenny (1986). Unfortunately, there are several important problems with it. More specifically, as we demonstrate below, it: (a) is of virtually no value for buttressing claims of mediating effects for data from non-experimental research; (b) produces erroneous inferences about the existence of mediating effects for misspecified mediation models; and (c) is incapable of providing credible evidence of such effects in a large proportion of cases, even for properly specified mediation models. We detail a number of important implications of our analyses.

This paper aims to examine, building upon affect balance theory, whether the two modes of luxury consumption, conspicuous consumption (CC) and style consumption (SC), trigger consumers’ mixed emotions of pleasure and guilt and whether the mixed emotions interactively as well as independently influence consumer loyalty to repurchase luxury.

Using an online survey and seemingly unrelated regressions (SUR) analysis, the authors test the hypotheses and assess the parallel (double) mediation effects of pleasure and guilt on the relationships between luxury consumption and repurchase intention.

The authors confirm the relationships between CC and pleasure (+), between SC and pleasure (+), between CC and guilt (+) and between SC and guilt (−); the independent effects of pleasure (+) and guilt (−) on repurchase intention (RI); and the interaction effect of pleasure and guilt on RI (+). The authors further demonstrate that both pleasure and guilt mediate the relationship between CC and RI, whereas only pleasure mediates the relationship between SC and RI.

Future researchers may consider possible mixed emotions other than pleasure and guilt and further explore the dynamics between mixed consumer emotions and consumer loyalty in diverse consumption contexts.

The authors suggest luxury marketers to reduce consumer guilt by promoting SC and by maximizing consumer pleasure, which will lead to greater repurchase intention.

Prior research focused on either the positive or negative side of consumer emotion. The authors fill in the research void by examining whether mixed emotions coexist in luxury consumption and how they interplay and influence consumer loyalty.

This article analyzes two of the determinants of the effectiveness of the mediation process, namely the impact of different mediators and mediation behavior on mediation outcomes in international relations. We review the literature and consider this relationship in terms of specific hypotheses concerning (1) the identity of a mediator, (2) previous interactions with the parties, (3) previous mediation attempts, and (4) the nature of mediation strategy. An original data set of 97 international disputes and 364 mediation attempts in the post‐1945 period is utilized to test our hypotheses. Multivariate analysis suggests the significance of high mediator rank, directive strategy, and close political alignment in achieving successful outcomes. We use these results to posit and test a series of causal models of mediation.

Information and communications technology (ICT) offers enormous opportunities for individuals, businesses and society. The application of ICT is equally important to economic and non-economic activities. Researchers have increasingly focused on the adoption and use of ICT by small and medium enterprises (SMEs) as the economic development of a country is largely dependent on them. Following the success of ICT utilisation in SMEs in developed countries, many developing countries are looking to utilise the potential of the technology to develop SMEs. Past studies have shown that the contribution of ICT to the performance of SMEs is not clear and certain. Thus, it is crucial to determine the effectiveness of ICT in generating firm performance since this has implications for SMEs’ expenditure on the technology. This research examines the diffusion of ICT among SMEs with respect to the typical stages from innovation adoption to post-adoption, by analysing the actual usage of ICT and value creation. The mediating effects of integration and utilisation on SME performance are also studied. Grounded in the innovation diffusion literature, institutional theory and resource-based theory, this study has developed a comprehensive integrated research model focused on the research objectives. Following a positivist research paradigm, this study employs a mixed-method research approach. A preliminary conceptual framework is developed through an extensive literature review and is refined by results from an in-depth field study. During the field study, a total of 11 SME owners or decision-makers were interviewed. The recorded interviews were transcribed and analysed using NVivo 10 to refine the model to develop the research hypotheses. The final research model is composed of 30 first-order and five higher-order constructs which involve both reflective and formative measures. Partial least squares-based structural equation modelling (PLS-SEM) is employed to test the theoretical model with a cross-sectional data set of 282 SMEs in Bangladesh. Survey data were collected using a structured questionnaire issued to SMEs selected by applying a stratified random sampling technique. The structural equation modelling utilises a two-step procedure of data analysis. Prior to estimating the structural model, the measurement model is examined for construct validity of the study variables (i.e. convergent and discriminant validity).

The estimates show cognitive evaluation as an important antecedent for expectation which is shaped primarily by the entrepreneurs’ beliefs (perception) and also influenced by the owners’ innovativeness and culture. Culture further influences expectation. The study finds that facilitating condition, environmental pressure and country readiness are important antecedents of expectation and ICT use. The results also reveal that integration and the degree of ICT utilisation significantly affect SMEs’ performance. Surprisingly, the findings do not reveal any significant impact of ICT usage on performance which apparently suggests the possibility of the ICT productivity paradox. However, the analysis finally proves the non-existence of the paradox by demonstrating the mediating role of ICT integration and degree of utilisation explain the influence of information technology (IT) usage on firm performance which is consistent with the resource-based theory. The results suggest that the use of ICT can enhance SMEs’ performance if the technology is integrated and properly utilised. SME owners or managers, interested stakeholders and policy makers may follow the study’s outcomes and focus on ICT integration and degree of utilisation with a view to attaining superior organisational performance.

This study urges concerned business enterprises and government to look at the environmental and cultural factors with a view to achieving ICT usage success in terms of enhanced firm performance. In particular, improving organisational practices and procedures by eliminating the traditional power distance inside organisations and implementing necessary rules and regulations are important actions for managing environmental and cultural uncertainties. The application of a Bengali user interface may help to ensure the productivity of ICT use by SMEs in Bangladesh. Establishing a favourable national technology infrastructure and legal environment may contribute positively to improving the overall situation. This study also suggests some changes and modifications in the country’s existing policies and strategies. The government and policy makers should undertake mass promotional programs to disseminate information about the various uses of computers and their contribution in developing better organisational performance. Organising specialised training programs for SME capacity building may succeed in attaining the motivation for SMEs to use ICT. Ensuring easy access to the technology by providing loans, grants and subsidies is important. Various stakeholders, partners and related organisations should come forward to support government policies and priorities in order to ensure the productive use of ICT among SMEs which finally will help to foster Bangladesh’s economic development.

The purpose of this paper is to explore the existing mechanism through which business group affiliated firms in emerging markets (EMs) continue to generate superior performance.

The authors build our argument on the basis of how business group affiliation in EM facilitates internationalization and investment into innovation in affiliated firms compared to un-affiliated firm, resulting in higher firm performance. The authors use advance statistical modeling – causal mediation analysis to separate direct effect and indirect effect of business group affiliation in EM on performance through internationalization and investment into innovation of business group affiliated firms as mediating variables.

Based on 122,479 observations (firm year) from 17,235 Indian business group affiliated and un-affiliated firms, the findings help to identify that internationalization and investment into innovation of business group affiliated firms do have a mediating role in affiliation–performance relationship for EM business groups.

This study unravels the existing causal chain between business group affiliation in EMs and subsequent performance of affiliated firms. The authors complement institutional argument for superior performance of business group affiliation and focus on the performance implication of mediating strategic decisions in affiliated firms.
