The purpose of this paper is to present a model that retailers engaged in e‐commerce (e‐tailers) can use for determining the optimal mix of customer segments within a customer portfolio from an integrated risk and return perspective.

Portfolio Selection Theory of Markowitz is applied to find the optimal composition of customer portfolios. The model is developed and discussed for two customer segments (relationship‐ and transaction‐oriented customers) and exemplarily applied to a data set of an e‐tailer.

Portfolio Selection Theory of Markowitz is well‐suited and promising for determining an optimal customer portfolio from a risk‐return perspective. However, since customers vary from financial assets in several aspects, the results of the model have to be interpreted conscientiously and the resulting action options have to be interpreted within the context of customer relationship management (CRM).

The model proposes to carry out a sequential set of one‐period optimizations. To reduce complexity, several simplifying assumptions were made within the model regarding the characteristics of customer segments and portfolio as well as the expected risk and return.

A current survey among German companies indicates that companies already have broad experiences in customer evaluation. However, it also turned out that evaluating customers' potential and risk simultaneously is still a major challenge. Our new approach facilitates the making of sound investment decisions into single customer relationships with respect to an overall optimal customer portfolio. Thus, a formal link to value‐based management is established.

Using CRM for a value‐based management of customer portfolio according to a superordinated risk management objective has so far received little attention in literature. This paper's model is a new approach in customer portfolio management for e‐tailers taking customers' risk and return characteristics simultaneously and in real‐time into consideration.

This study aims to identify the price determinants of fine wines in a small and competitive market. These characteristics are found in many lesser-known wine-producing countries and are often difficult to analyse because of lack of data.

This study hand-collects and transcribes wine-related data for 149 Swiss wineries and 2,454 individual wines over the period 2014–2018 directly from wine lists provided by wineries. This study uses multivariate ordinary least squares regressions to analyse the relation between wine attributes and prices and to assess the effect of a currency shock caused by the sudden appreciation of the Swiss franc in 2015 as well as a reduction in information asymmetries induced by the novel coverage of Swiss wines by The Wine Advocate.

Prices mainly depend on collective reputation, production techniques and product positioning. Surprisingly, following a sharp appreciation of the Swiss franc, producers did not reduce prices. The arrival of a highly influential wine expert on the market also had a positive price effect on rated wines and producers. Both hint at wineries attempting to position themselves relative to competitors.

Few studies examine the price drivers in lesser-known wine markets, where competition is fierce. This study’s results show that wine pricing differs from other more famous and larger wine regions. In addition, to the best of the authors’ knowledge, this study is also the first to analyse the impact of a currency shock and a reduction in information asymmetries on wine prices.

While the career literature does acknowledge that personal strengths may function as protective factors that increase the likelihood of positive career outcomes, the topic of strengths has predominantly been studied in the context of career guidance for adolescents and young adults. However, the evolution of strengths persists throughout the entire career and individuals’ awareness and inclination to leverage their strengths change when aging. This paper aims to examine strengths over the (career) lifespan.

For this purpose, a conceptual analysis was made of the interplay between age and strengths application within the work environment, based on a narrative review of both empirical and conceptual literature on strengths and lifespan (career) development.

Based on lifespan development theory and results from studies that investigate the relationship between age and strengths, it can be expected that the prominence, awareness and use of strengths, as well as the active engagement in strengths development increase with age. Also, based on the corresponsive principle it is proposed that strengths prominence is reciprocally related to the awareness, use and development of strengths. Implications for future research and practice are discussed.

Whereas positive psychology has contributed to research on career development by its focus on healthy functioning, human potential and well-being the implications from theorizing and research on strengths for the career-lifespan are still relatively unclear. This paper develops testable propositions regarding the relationship between age and strengths and discusses implications for the types of organizational support for strengths that workers of different ages might need.

The purpose of this paper is to illustrate how the Wirecard scandal has highlighted the need for further reforms in Germany and Europe, exposing institutional and market oversight weaknesses, particularly in terms of market integrity and investor protection.

To provide a comprehensive picture of the situation, this paper is based only on relevant studies, which focus on the topic of interest, namely, the context of the Wirecard collapse in June 2020. It also examines how internal and external governance and monitoring mechanisms failed to uncover major fraud within the German payments group earlier.

This study shows that this is by no means an isolated or unpredictable incident, and the allegations of accounting fraud had been known for several years, thanks to warnings from the Financial Times. In addition, the paper reviews the serious shortcomings revealed in the Wambach report. The report provided private details of the Wirecard audit and documents on the relationship between Wirecard management and the auditor. All of this can serve as a reference point for institutional and market oversight architecture in Germany and Europe and pave the way for future research.

The paper contributes to the literature by highlighting the implications of the Wirecard scandal and the lessons that can be learned from what was one of Germany’s biggest corporate scandals especially at a time when many are already affected by the impact of COVID-19 on the entire financial services industry.

The purpose of this paper is to understand how the digital workplace, in particular employees using consumer tools at work (users), impacts how internal IT departments function and their relationships with users they have historically supported.

An interpretive, longitudinal case study highlighting how one IT department coped with the conflicts using consumer tools at work creates a trend called IT consumerization.

Internal IT departments manage the conflicts IT consumerization poses through an ongoing process of conflict and conflict resolution. This impacts the IT department’s relationship with users along three dimensions: IT-control, user-self-sufficiency and IT-user partnerships.

While there is an ongoing debate about internal IT departments needing to change, the study shows how one IT department did change in response to IT consumerization. The authors develop a data-driven model grounded in theories that explains how IT departments cope with the conflicts IT consumerization poses.

The aim of the present study was to examine the association of subordinate-oriented strengths-based leadership (SSBL) with subordinates’ job performance (task performance and innovative behavior) as well as the meditating role of supervisor–subordinate guanxi (SSG) in these relationships.

Self-report data on SSBL, SSG, task performance and innovative behavior were gathered from 642 Chinese employees working in various Chinese enterprises. Structural equation modeling was used to analyze the data.

The results indicated that SSBL is positively related to subordinates’ job performance (task performance and innovative behavior). Furthermore, SSG partially mediated the relationship of SSBL with task performance and with innovative behavior.

This study is the first to empirically examine the relationship of SSBL with job performance. In addition, this study adds to the knowledge on the SSBL–job performance linkage by investigating the mediational effect of SSG on the relationship.

Ubiquitous digital technologies are driving organisations to embrace non-traditional digitally transformed business models incessantly. Heterogeneous literature contributions have resulted in a spur in the research related to business transformation driven by digital technologies in recent years; consequently, the research under the digital transformation (DT), even though becoming a hotspot, remains very fragmented. The authors endeavour to holistically present the literature's intellectual structure under DT as a concept, its evolving journey and the emerging research streams in the business and management domains using the techniques of bibliometric analysis.

By performing bibliometric analysis on 234 research articles published over the last 20 years in the DT domain, retrieved from Thompson Reuters Web of Science ^TM, this study culls out thorough insights from the citation, co-citation and keyword analysis. Further emerging research streams were evaluated using VOSviewer software.

The study depicts an overall incremental trend of year-on-year publications, authors' performance, publication journals, associated institutions and research driving countries, along with key insights from co-citation network analysis. Furthermore, the study evaluates four research areas – organisational impacts, applied applications and insights, operational processes and social aspects, comprising eighteen research streams that comprehensively cover-up research under the DT domain.

The study contributes to the literature of DT by amalgamating the status of the present research, but more importantly, by deriving the research areas and research streams, which can be further expanded by researchers as future research streams.

For the practitioners, the study aims to act as a ready reckoner repository with practice-oriented literature references to facilitate them building knowledge and taking effective strategic decisions to harness the benefits of DT more proficiently.

This study illustrates the bibliometric structure of the DT literature and presents insights from the growth of the literature year-on-year.

The purpose of this essay is to illustrate how project management “pull” and AI or analytics technology “push” are likely to result in incremental and disruptive evolution of project management capabilities and practices.

This paper is written as a critical essay reflecting the experience and reflections of the author with many ideas drawn from and extending selected items from project management, artificial intelligence (AI) and analytics literatures.

Neither AI nor sophisticated analytics is likely to elicit hands on attention from project managers, other than those producing AI or analytics-based artifacts or using these tools to create their products and services. However, through the conduit of packaged software support for project management, new tools and approaches can be expected to more effectively support current activities, to streamline or eliminate activities that can be automated, to extend current capabilities with the availability of increased data, computing capacity and mathematically based algorithms and to suggest ways to reconceive how projects are done and whether they are needed.

This essay includes projections of possible, some likely and some unlikely, events and states that have not yet occurred. Although the hope and purpose are to alert readers to the possibilities of what may occur as logical extensions of current states, it is improbable that all such projections will come to pass at all or in the way described. Nonetheless, consideration of the future ranging from current trends, the interplay among intersecting trends and scenarios of future states can sharpen awareness of the effects of current choices regarding actions, decisions and plans improving the probability that the authors can move toward desired rather than undesired future states.

Project managers not involved personally with creating AI or analytics products can avoid mastering detailed skill sets in AI and analytics, but should scan for new software features and affordances that they can use enable new levels of productivity, net benefit creation and ability to sleep well at night.

This essay brings together AI, analytics and project management to imagine and anticipate possible directions for the evolution of the project management domain.

At 9 a.m. on 31 August 1988, Delta Flight 1141 crashed on take‐off, killing 13 people and leaving 94 survivors. Existing research has furthered our insight into media coverage of disasters but it has not broadened our understanding of disaster narrative interpretations and disaster behaviour education. In total, 24 in‐depth interviews explore reader interpretations of print‐mediated disaster reality and the Delta 1141 disaster. Disaster news stories provide the frames people use to interpret aeroplane disaster behaviour. Concludes the media need to recognize that their pedagogical role extends beyond disaster reporting and includes disaster behaviour information.
