Abstract

Purpose

The paper aims to assess the potential of aircraft operation from city centres to achieve shortened travel times and the involved aircraft design process.

Design/methodology/approach

The paper describes the methodical approach and iterative procedure of the design process. An assessment of potential technologies is conducted to provide the required enhancements to fulfil the constraints following an inner-city operation. Operational procedures were analysed to reduce the noise propagation through flight path optimization. Furthermore, a ground-based assisted take-off system was conceived to lower required take-off field length and to prevent engine sizing just for the take-off case. Cabin design optimization for a fast turnaround has been conducted to ensure a wide utilization spectrum. The results prove the feasibility of an aircraft developed for inner city operation.

Findings

A detailed concept for a 60-passenger single aisle aircraft is proposed for an Entry-Into-Service year 2040 with a design range of 1,500 nautical miles for a load factor of 90 per cent. Although the design for Short Take-off and Landing and low noise operation had to be traded partly with cruise efficiency, a noteworthy reduction in fuel burn per passenger and nautical mile could be achieved against current aircraft.

Practical implications

The findings will contribute to the evaluation of the feasibility and impact of the Flightpath 2050 goal of a 4-h door-to-door by providing a feasible but ambitious example. Furthermore, it highlights possible bottlenecks and problems faced when realizing this goal.

Originality/value

The paper draws its value from the consideration of the overall sizing effects at aircraft level and from a holistic view on an inner-city airport/aircraft concept design for a 4-h door-to-door goal.

Abstract

Purpose

The purpose of this paper is the multi-disciplinary conceptual investigation of a propulsive fuselage (PF) aircraft layout allowing for new performance synergies through closely coupled propulsion/airframe integration. The discussed aircraft layout facilitates the ingestion of the fuselage boundary layer and the utilization of wake filling, thus eliminating a significant share of fuselage drag.

Design/methodology/approach

Based on consistent book-keeping standards for conventionally installed and highly integrated propulsion systems, key aspects of conceptualisation regarding airframe and propulsion system are presented. As a result of this, a PF aircraft configuration is proposed featuring a fuselage fan power plant in conjunction with two under-wing podded power plants. Parametric models for integrated aircraft and propulsion system sizing and performance analysis are discussed that are suitable for the consistent mapping of the characteristics intrinsic to a PF layout. In an initial benchmarking exercise, the vehicular efficiency potentials of the previously identified PF configuration are evaluated against an advanced conventional reference aircraft.

Findings

During benchmarking, it was found that a best and balanced design for the proposed PF aircraft layout yields an increase in vehicular efficiency of approximately 10 per cent compared to the advanced conventional reference aircraft.

Practical implications

The paper gives the reader an idea for the efficiency potentials achievable through a PF aircraft configuration, as well as guidelines for aircraft sizing and integrational aspects. It may serve as a basis for advanced studies in the future.

Originality/value

The conceptual investigation of the PF concept idea, contributes to establishing the initial technical feasibility of this novel approach to synergistic propulsion system integration. The methods presented in this paper allow for the multi-disciplinary conceptual design sizing of a PF aircraft.

Abstract

Purpose

The proliferation of industry platforms has disrupted several industries. Firms adopting a platform business model have experienced a substantial expansion in size and scale, positioning themselves as the foremost valuable entities in market capitalization. Over the past two decades, there has been a substantial expansion in the body of literature dedicated to platforms, and different streams of research have emerged. Despite considerable efforts and the significant progress made in recent years toward a comprehensive understanding of industry platforms, there is still room for further harnessing the field’s diversity. As a result, the aim of this article is to examine the field’s structure, identify research concerns and provide suggestions for future research, thereby enhancing the overall understanding of industry platforms.

Design/methodology/approach

We conducted a thorough examination of 458 articles on the topic using bibliometric methods and systematic review techniques.

Findings

Through co-citation analysis, we identified five distinct clusters rooted in various bodies of literature: two-sided markets, industry platforms, digital platforms, innovation platforms and two-sided networks. Furthermore, the examination of these five clusters has revealed three key areas that demand further consideration: (1) terminologies, (2) classifications and (3) perspectives.

Originality/value

While previous reviews have provided valuable insights into the topic of industry platforms, none have explored the structure of the field so far. Consequently, as a first step toward advancing the field, we uncover the structure of the literature, identifying three major areas of concern. By addressing these concerns, our goal is to converge different clusters, thereby harnessing the diversity in the field and enhancing the overall understanding of industry platforms.

Abstract

Purpose

Citizenship behaviours are used in organisation studies to explain their effectiveness and to capture the role of unsolicited, extra-role behaviours. Recent extensions towards the interorganisational context provide evidence that Interorganisational Citizenship Behaviours (ICBs) are important in facilitating supply chain operations and cluster innovation activities. This study took stock of citizenship behaviours literature within and among organisations, in order to develop and validate a measurement scale for ICBs useful in the food industry and beyond.

Design/methodology/approach

Departing from a literature driven 10-dimensional construct, Th authors proceeded with validating our scale in the South African craft brewing industry. The authors ran a face validation, followed by confirmatory and exploratory factor analyses on a sample of 108 expert informants. The authors ran nomological tests through correlation and regression analysis. Finally, logical analysis was done to ensure the theoretical integrity of the mathematical indications.

Findings

The authors found support that the model consisting of interorganisational magnanimity, interorganisational advancement and interorganisational constructiveness, is relevant for value creation within coopetitive networks. The purified scale included three psychometrically distinct ICBs dimensions, measured by 31 items.

Practical implications

Managers can benefit from adequately identifying ICB in their environment, and among their competitors in particular. The study’s measurement scale offers a useful tool for an initial monitoring of firms in their competitive environment.

Originality/value

The authors extended and advanced prior research on the ICB construct by providing a rigorously validated, parsimonious measurement scale of ICBs. The authors bridged the ICB and coopetition literature to better understand spontaneous extra-role coopetitive network facilitating behaviours.

Abstract

Purpose

This article investigates (in)direct relationships between team-level entrepreneurial orientation and team performance, where team entrepreneurial orientation (EO) is measured as a team-level construct, not as concentration of team members' scores. In this article, the authors present and explore how EO-oriented behaviour within a team affect its performance, taking into account the team's trust in a manager and commitment to team and company goals.

Design/methodology/approach

This article focuses on a quantitative analysis of 55 teams operating within a large high-tech manufacturing enterprise, gathered through a traditional survey. The conceptual framework for this research was based on the theories of organisational citizenship, extra-role behaviour and social exchange. The authors explain how contextual factors establish a framework which enables team EO transformation towards higher performance of teams.

Findings

The results show that (team) performance benefits from EO-related behaviours. However, individual dimensions of EO are not universally beneficial and need to be combined with a mutual trust and/or commitment to team enterprise's goals to achieve high performance.

Originality/value

The findings provide important insight into which team factors may be targeted at the intervention or support of team members, including managers and immediate superiors who lack an active personality and are not willing to take risks at workplace. The authors adopted EO instruments, mutual trust and commitment from an individual scale to a team one, and also offer new opportunities to analyse such phenomena from a new level and evaluate them from the perspective of team managers.

Abstract

Purpose

The purpose of this paper is to explore consumers’ responses to emotional and normative communication in comparison with traditional informational campaigns promoting pro-environmental behavior in the context of biodiversity. By adopting the approach of likeability of the communication, the paper identifies which type of communication strategy is liked by consumers’ and which dimensions define likeability in the context of biodiversity. The goal is to improve the effectiveness of communication messages delivered by social marketers or public policy makers through a better understanding of consumers’ responses to different communication strategies.

Design/methodology/approach

To investigate which communications strategies are perceived as likeable in the context of promoting biodiversity and to explore the dimensions that underlie likeability of the communication a qualitative study was conducted. First, the information design with the different communication strategies has been developed. Second, focused interviews with 25 individuals have been conducted.

Findings

Results indicate that communication strategies using positive emotions led to most favorable responses. Further, findings suggest that informational strategies seem to result in positive attitudes when they tap on procedural knowledge. Favorable judgments are linked with communication strategies that create awareness or which are relevant and informative.

Research limitations/implications

Further empirical research is suggested exploring consumers’ responses to communication strategies that combine emotions and facts.

Practical implications

Based on the findings of this study, social marketers and public policy makers are recommended to use a combination of communication strategies that evoke positive emotions and provide consumers with the facts necessary to take action.

Originality/value

The paper allows for an integrated view and contributes to an increased understanding of responses to communication strategies and provides valuable practical implications for social marketers and public policy makers.

Abstract

Purpose

This study aims to investigate the association between narcissistic tendencies, gender and funding success in high-growth start-ups. It aims to bridge a critical research gap by exploring the combined effect of gender and narcissism on start-up funding success.

Design/methodology/approach

The authors surveyed 540 founders of high-growth start-ups in Germany, Austria and Switzerland, using the NPI-16 questionnaire to assess narcissistic tendencies. By focusing on high-growth start-ups as opposed to small firms, the authors enhanced the validity of the sample. This study isolates and analyses the effects of gender and narcissism, providing insights into their individual and combined contributions to start-up funding success.

Findings

The findings reveal that gender is associated with lower start-up funding and lower narcissistic tendencies. This highlights the intricate relationship between gender, narcissism and funding success within the context of high-growth start-ups.

Practical implications

These findings have important implications for investors, policymakers and entrepreneurial educators, suggesting that a nuanced understanding of founders’ psychological traits could enhance funding strategies and start-up support mechanisms.

Originality/value

This research addresses the critical gap in the literature by examining the joint influence of gender and narcissism on funding success in high-growth start-ups. The study contributes to a nuanced understanding of the factors shaping founder psychology and performance dynamics, offering valuable insights for future research in gender, narcissism and start-up success.

Abstract

Purpose

The article discusses the current relevance of artificial intelligence (AI) in research and how AI improves various research methods. This article focuses on the practical case study of systematic literature reviews (SLRs) to provide a guideline for employing AI in the process.

Design/methodology/approach

Researchers no longer require technical skills to use AI in their research. The recent discussion about using Chat Generative Pre-trained Transformer (GPT), a chatbot by OpenAI, has reached the academic world and fueled heated debates about the future of academic research. Nevertheless, as the saying goes, AI will not replace our job; a human being using AI will. This editorial aims to provide an overview of the current state of using AI in research, highlighting recent trends and developments in the field.

Findings

The main result is guidelines for the use of AI in the scientific research process. The guidelines were developed for the literature review case but the authors believe the instructions provided can be adjusted to many fields of research, including but not limited to quantitative research, data qualification, research on unstructured data, qualitative data and even on many support functions and repetitive tasks.

Originality/value

AI already has the potential to make researchers’ work faster, more reliable and more convenient. The authors highlight the advantages and limitations of AI in the current time, which should be present in any research utilizing AI. Advantages include objectivity and repeatability in research processes that currently are subject to human error. The most substantial disadvantages lie in the architecture of current general-purpose models, which understanding is essential for using them in research. The authors will describe the most critical shortcomings without going into technical detail and suggest how to work with the shortcomings daily.

Abstract

Purpose

The purpose of this paper is to offer an understanding as to whether trust‐based coordination is feasible in the context of small and medium‐sized enterprises (SME) internationalization processes, and if so, what impact these cooperative arrangements can have on corporate success.

Design/methodology/approach

To answer the research hypotheses, multiple regression analyses based on a postal questionnaire survey (n = 58 SMEs from Austria, the Czech Republic and Slovenia) were computed.

Findings

It is found that self‐commitment facilitates the establishment and maintenance of heterarchic cross‐border cooperation relationships of SMEs that cannot evolve based on market or hierarchical coordination. It is also found that the establishment of trust‐based cooperation relationships with foreign partners positively affects the success of the participating companies.

Research limitations/implications

Only Slovenian and Czech enterprises and their internationalization have been investigated and compared to Austrian enterprises. Only SMEs have been investigated, no large companies. It is not clear that the presented empirical findings also hold true for larger enterprises.

Practical implications

Active measures such as building more knowledge (getting to know) and openly approaching other enterprises should be encouraged in internationalization processes. Thus, protectionist labor market politics on the macro level are highly counterproductive. At the micro level, parties involved should acquire specific knowledge (e.g. languages or social codes) as well as that they replace prejudices and skepticism by profound knowledge on and openness towards the other, e.g. through exchange programs for employees.

Originality/value

The paper is the first to analyze the role of trust‐based cooperation relationships on the internationalization processes of SMEs in the context of Austrian and Central and Eastern Country (CEEC) enterprises. The results of this research can become important for SMEs which want to pursue an internationalization strategy in the context of the CEEC.

Abstract

Purpose

The purpose of this paper is to analyze the leadership decisions taken during the crisis and their influence on the goals recognized by managers as crucial for surviving.

Design/methodology/approach

During the survey, conducted in April 2020 (one month after the first economic lockdown in Poland), as part of a research project called Sur(VIR)val – Survival during the virus, data was collected from 178 leaders from randomly selected companies from Poland using the CAWI method. Ordered logistic regression modeling was used to examine the impact of the decisions taken by company leaders on the goals seen by leaders as most important for company survival.

Findings

The results obtained in the study show that during the first Covid-19 lockdown in 2020, leaders made decisions that can be seen as oriented toward survival and continuity. Changing to remote working, extending payment deadlines for customers, as well as selective employment reduction turned out to have the greatest influence on strategic support for maintaining current production levels and retaining competent employees in order to survive the crisis.

Research limitations/implications

This study has certain limitations. First, the list of leadership decisions and company goals used as dependent variables is not exhaustive. Second, the selection of business goals oriented toward survival may not derive directly from the lockdown situation. Third, our study did not measure the actual accomplishment of the company goals, but the managerial perceptions as to which ones are crucial for company survival during crises, and which of them should be given strategic support respectively. Fourth, the research sample was randomly constructed and covered only business organizations in Poland. Fifth, the hypotheses were formulated in a way that treated leadership decisions as one construct. Finally, we used survey, with a scale measuring managerial perceptions.

Practical implications

Leaders should ensure that proper IT tools are developed within the organization, and that the skill level of employees is high enough for fast shifting employees on to remote working. At the same time, it is important to maintain IT infrastructure at a high level. In terms of general recommendations for leaders, they should make quick decisions, maintain the most valuable resources of the company (human resources and cash flow) and take actions aimed at taking advantage of opportunities (R&D) during and after the crisis.

Social implications

Additionally, due to the key importance of human resources for the survival of the organization, leaders should respond quickly by making flexible decisions about sending employees on leave and downtime. As human resources are the most valuable assets of the company from the point of view of its survival, decisions concerning employment reduction should be taken carefully. Leaders who acted in panic after the first lockdown and made employees redundant, later on had problems recruiting skilled employees back and strived to return to full organizational capacity.

Originality/value

Although scholars have investigated leadership decisions and actions taken during economic crises, little is known about how leaders behave when taken by surprise, and what decisions they make when the duration of a crisis is difficult to predict. The results of this study show which leadership decisions during the first Covid-19 lockdown in 2020 influenced prioritizing critical company goals oriented toward survival.
