The purpose of this research is to explore the nature of virtual tipping in live game streaming from the perspective of tippers.

This qualitative research involved six naturalistic group interviews with 27 young adult game streaming tippers in China.

The research revealed a typology of four virtual tipping exchanges – perfunctory exchange, transactional (commodity) exchange, relational (gift) exchange and hybrid exchange. The most notable finding is hybrid exchange, a synergistic hybrid of transaction and gift-giving.

The authors recommend that both streamers and streaming platforms acknowledge and accommodate both transactional and relational tipping motivations. The authors also recommend platforms to recruit skillful streamers with high emotional intelligence to better convert perfunctory tippers into tippers who tip more generously.

The result of hybrid exchange suggests going beyond the traditional commodity vs gift dichotomy to examine the potential market-gift complementary in a single exchange in the sharing economy.

This study aims to understand the characteristics and formation of artists’ production sensibilities and relations with other actors within an emerging hybrid art market structure.

To unravel senses and map out relationships and structures in the context of this study, qualitative methods, including in-depth interviews and analysis of secondary data sources, were applied.

The authors describe three art production sensibilities and market-based relationship logics rooted in the artist and the artwork’s diverse role in the market.

The findings suggest that artistic sensibilities motivate managers working in the hybrid art market to develop a more nuanced positioning of artists and their creative outputs to improve harmony and collaboration.

This study demonstrates that the hybrid structure of art markets allows for the harmonious separation and collaboration of non-market (artistic) and market logics. This study uncovers how artists combine their non-market creative position with market needs in the process of marketization and hybridization.

This paper aims to show that a generic bottom-of-the-pyramid (BoP) segmentation strategy does not represent a multi-country BoP consumer profile. A series of multinational entry failures has clearly shown that a one-size-fits-all strategy is inappropriate for emerging markets, especially in Africa.

The study analysed literature defining and profiling BoP consumers at both a global and local level using South Africa as a case study. Being Africa’s largest economy, South Africa was an ideal subject. The findings were then independently triangulated with seven experts for validation.

The results show that the South African BoP has eight characteristics that align with definitions in global BoP consumer literature. An additional five characteristics were identified that were not general BoP characteristics, and that applied specifically to South Africa.

The findings add to the growing evidence that BoP markets are complex and heterogeneous, and they make a case to consider each BoP market individually. As there is yet to be a model to define BoP market differences systematically, this study provides a foundation for new developments in BoP segmentation in Africa and in other emerging markets.

While there is evidence that BoP markets are complex and heterogeneous, there is yet to be a model to begin the process of defining these differences systematically to improve strategic direction for multinational companies and regional decision makers. This study, therefore, provides a foundation for new developments in this field of segmentation in Africa and in other emerging markets globally.

The purpose of this paper is to explore how the entrepreneurs' social connections and types of employment differentially affect the survival of startup firms in the USA and India. Further, the authors analyze the differences during both the early stage and the later stages of new ventures.

The authors use data from the Global Entrepreneurship Monitor (GEM) database between 2012 and 2014 and examine the hypothesized effects with logistic regression analyses.

The analysis reveals that an entrepreneur's social connections with other entrepreneurs favor the survival of the focal entrepreneur's early-stage business in the USA. However, social connections are more critical for later-stage ventures in India. During the early stage, new ventures of full-time entrepreneurs are more likely to survive in India, whereas those by hybrid entrepreneurs are more likely to survive in the USA. The differences between the importance of full-time and hybrid entrepreneurs across geographies are less discernible during the later stages of new ventures.

The novelty of this paper is that it demonstrates the significant differences in the way social connections and types of employment (hybrid versus full-time) affect the survival of entrepreneurial firms in the early and later stages. The study also expands the international business literature by shedding new light on country-level differences that affect the survival of new ventures.

This paper aims to develops an estimable hybrid model that combines the micro‐founded DSGE model with the flexibility of the atheoretical VAR model.

The model is estimated via the maximum likelihood technique based on quarterly data on real gross national product (GNP), consumption, investment and hours worked, for the South African economy, over the period of 1970:1 to 2000:4. Based on a recursive estimation using the Kalman filter algorithm, the out‐of‐sample forecasts from the hybrid model are then compared with the forecasts generated from the Classical and Bayesian variants of the VAR for the period 2001:1‐2005:4.

The results indicate that, in general, the estimated hybrid‐DSGE model outperforms the classical VAR, but not the Bayesian VARs in terms of out‐of‐sample forecasting performances.

The model lacks nominal shocks and needs to be extended into a small open economy framework.

The paper was able to show that, even though the DSGE model is outperformed by the BVAR, a microfounded theoretical DSGE model has a future in forecasting the South African economy.

To the best of the authors' knowledge, this is the first attempt to use an estimable DSGE model to forecast the South African economy.

This study empirically aims to examine the collaboration between social enterprises (SEs) and impact investors (IIs), which are organisations with similar interests but with distinct logics, and in high demand in emerging economies with complex problems. Despite the significant economic contributions of these organisations, there have been limited studies examining how they collaborate in different contexts, including theoretical insights explaining how they gain partner fit from resource synergy.

Mainstream businesses use the compatibility and complementarity concepts to examine buyer–supplier strategic alliances. Using similar concepts in the context of hybrid organisations, the authors interviewed six pairs of SEs and IIs with dyadic relations in Nigeria, aiming to deeply understand how they align dissimilar logics in pursuing common goals in emerging economies.

The authors’ findings revealed how compatibility criteria from the institutional logics perspective and complementarity from social exchange theory guide collaboration between SEs and IIs in an emerging economy. Using these theories provides new insights that distinguish SEs and IIs collaboration from conventional theories on the internationalisation of businesses, which remained insufficient for understanding the cross-border operations of SEs.

The study holds practical implications for organisations, regardless of their size, international investors, governments, organisations and individuals desiring to pursue sustainable business agendas in emerging economies with huge impact opportunities and the process involved.

The outcomes of this study extend knowledge of the theoretical lens examining collaborative entrepreneurship from the perspective of hybrid organisations. It also challenged existing knowledge on collaboration between SEs and IIs, often characterised by potential tensions due to the dissimilarity of institutional logics of actors.

The purpose of this study is to provide insight into characteristics of visitor demand for a regionally oriented vinotheque (wine bar and shop) at a UNESCO world heritage destination in Germany. The research especially focuses on expected offer components for a wine bar and shop, including wine-related products and services, to test the theoretical notion of blurred division between product and service offerings. The literature review has revealed that implications of this conceptual notion on wine bar and shop offer creation could be profound as there are different types of wine bar and shops with different product–service combinations. Moreover, the offer creation needs to take into account the overall needs of wine bar and shop visitors and consider them as experience seekers and not necessarily utility-maximizing players. In this sense, the paper expands previous research on vinotheques that primarily took the wine retail perspective.

The study deals with wine-related sales, offer design and the importance of tourism and hospitality for wine sales in a non-growing wine market. However, the concept of increasing wine sales through tourism and hospitality brings to the forefront the issues of creating integrated offerings of products and services. This is why, the study deploys the concepts of hybrid products and experience economy. The primary data have been collected via self-administered, paper-based questionnaire (Appendix 2) amongst visitors at the St. Goar/Loreley tourist destination. The goal has been to reveal the importance of a wine bar and shop as a wine sales channel, whether visitors are interested in visiting a wine bar and shop, what major expectations they have entering a vinotheque, as well as what major offer components of products and/or services are they interested in. Total sample size was N = 400. Major statistical procedure deployed was descriptive statistics, as well as PCA (principal component analysis) of expectations and offer analysis in regards to products and services.

By deploying the PCA on the data regarding interest in buying wine-related products and services, three offer configurations have been extracted, out of which only one is purely related to products, whilst the other two are hybrid products, meaning a combination of wine-related products and services. Relevance of architectural design illustrates that visitors also seek experience. These findings confirm previously discussed theories on the importance of integrating products and services into hybrid products and creating experience with a suitable combination of products and services.

Data collection has taken place in a confined timeframe (two summer months). No active measures have been taken to ensure the validity of the sample through quotas or similar techniques. The research sample and location are somewhat limited for making conclusions in other geographical regions, but replicating the study in different contexts can add to the comparability of the results on the level of Germany, but also internationally. The empirical evidence for superior customer value of hybrid offerings and integrating services into product-centric offer design is of paramount importance for selling wine in a highly competitive market in absence of market growth. Wine bar and shop allows to differentiate the offer by creating wine-related experience through a combination of product (wine and wine-related products), hospitality/gastronomic services and tourism services. The insights also illustrate the idea of new market opportunities via connecting converging industries.

The study contributes to close a gap identified in the literature review that German wineries lag wine-tourism activities. It provides advice in regards to offer design and hybrid offerings and an experiential experience supported by architectural design. Such an approach offers the potential to win market share in a non-growing market – an ambition of the players in the market but also an obvious challenge.

The findings contribute to regional development. Furthermore, arguments for cooperative behavior are provided. This should also help to minimize free ridership and its negative social implications.

The paper adopts a multidisciplinary approach to the creation of wine bar and shop offer. The results point out that offerings should be created around a core wine tourism product – regional and cellar door offer – and be expanded by “food design” – components, attractive architectural elements, as well as web shop services, thereby creating an advanced wine-related experience. It confirms the importance of theoretical concepts such as experience economy, hybrid products and solution provision in the case of wine bar and shop, by testing these concepts on the group of visitors at a German wine and cultural destination.

The purpose of this paper is to propose and compare two energy management strategies (EMSs). First, a classic method based on frequency separation with fixed limits on fuel cell (FC) power is presented and tested. Then, the improvement of the classic strategy is developed and implemented when the main enhancements are its ease of implementation, hydrogen economy and extending hybrid source lifetime.

The proposed EMS is developed using an online variable power limitation of the FC depending on the battery state of charge while ensuring that the energy of batteries remains in its operating depth of discharge (DOD) range.

In the objective to show the benefits of the developed strategy, a comparative analysis was conducted between two strategies. The simulation and experimental results show the effectiveness and gains obtained by the improved energy management system (IEMS) in terms of fuel economy (13 per cent) and decreasing the applied stress on the FC (22 per cent) which leads to a longer life span of the whole system.

The proposed approach is developed and tested by simulation. To confirm it, a test bench has been assembled as hardware in the loop (HIL) real-time system. The presented experimental results confirm the efficiency and show the providing gains of the IEMS.

The purpose of this study is to investigate the optimization of design and energy management in a parallel hybrid-electric powertrain to replace the conventional engine of an existing tactical unmanned aerial vehicle (UAV) equipped with a Wankel engine with a pre-defined flight mission. The proposed powertrain can work in four different operating modes: electric, thermal, power-assist and charging.

The power request at propeller axis of each flight segment is used as input for an in-house model that calculates the overall fuel consumption throughout the mission (Mfuel) and the maximum payload weight (Wpay) by means of an average-point analysis. These outputs depend on the energy management strategy that is expressed by the power-split ratio between engine and electric phase (Uphase) of each mission phase, according to which the components of the hybrid system are sized. The in-house model is integrated into an optimization framework to find the optimal set of Uphase and battery size that minimizes Mfuel and maximizes Wpay.

It was found a 3.24% saving of the fuel mass burned throughout the mission (or, alternative an improvement of endurance by 4.3%) with about the same maximum-payload mass (+0.2%) of the original configuration, or a smaller fuel saving with +11% more payload. The fuel saving of 3.24% corresponds to −3.25% in total emissions of CO₂ and a 2.34% reduction of the cost-per-mission.

This study demonstrates that environmental advantages, even if limited, can be already obtained from optimal design and management of the hybrid power system with today technologies while waiting for further benefits from the introduction of advanced technologies for batteries and electric machines.

The main novelties are the design of the powertrain on the basis of the energy management and the application of scalability and hybridization to Wankel engines.

This paper aims to examine the role of technology in shaping the interplay between intimate and economic relations in collaborative consumer networks (CCNs).

This research is based on a three-year participatory netnographic and ethnographic field study of hosts, guests and community members within the Airbnb home-sharing network in New Zealand. The data consist of interviews, online and offline participant observations and brief discussions onsite (large-scale Airbnb events, host meetups and during Airbnb stays).

The findings reveal how technologies shape the relational work of home-sharing between intimate and economic institutions through grooming, bundling, brokerage, buffering and social edgework. This paper proposes a framework of triadic relational work enacted by network actors, involving complex exchange structures.

This study focusses on a single context – a market-mediated home-sharing platform. The findings may not apply to other contexts of economic and social exchanges.

The study reveals that the construction of specific relational packages by Airbnb hosts using their digital technologies pave a path for home-sharing to skirt the norms of the home as a place of intimacy and the market as a place for economics. This allows these two spheres to flourish with little controversy.

By augmenting Zelizer’s relational work, this study produces theoretical insights into the agentic role of technology in creating and stabilising a CCN.
