Corporate accelerators are a rapidly growing entrepreneurial phenomenon occurring in different business contexts and business models within corporate entrepreneurship. Corporate accelerators are considered as an innovation fostering approach within new ventures provided by start-ups. The aim of the paper is twofold: firstly, to explore the motives behind corporations' engagement with start-ups in launching corporate accelerators, and secondly, to identify the corporate benefits and challenges of this business model innovation. The research design is based on a qualitative interpretative approach exploiting a triangulation of methods by using in-depth interviews (IDI) with corporate managers involved in development of corporate accelerators as well as a focus group interview (FGI) with industry experts. In addition, secondary data were applied to strengthen the exploratory research. The study demonstrates that a wide range of benefits stem from the accelerator activities which can ultimately can initiate changes in large companies. Our research expands on prior findings and suggests that corporate accelerators are driven by internal and external push and pull motives. The study contributes to expanding the scope of corporate entrepreneurship research in regard to the challenges and benefits of corporate accelerators. It provides evidence that corporate accelerators are a source of innovation that can be used to foster entrepreneurial-market logic and entrepreneurial learning.

A B S T R A C T Objective:Based on extensive literature review, this paper aims to establish if, why and how, in given environmental and market contexts, social entrepreneurship (SE) opportunities are discovered and exploited. It positions social problems as sources of entrepreneurial opportunity. The article presents an integrated process-based view of SE opportunity antecedents and concludes with a dynamic model of SE opportunity. Research Design & Methods:To fulfil its goal, the paper establishes opportunity as unit of research and explores the dynamics of opportunity recognition. To identify the components of SE opportunity through a process-based view, the study follows the steps of critical literature review method. The literature review follows with logical reasoning and inference, which results in the formulation of a model proposition of social entrepreneurship opportunity.

Purpose -The purpose of this paper is to examine the relationship between routine communication practices and corporate entrepreneurship (CE). Drawing upon CE theory and neo-bureaucratic theory, the paper provides insight into all the directions of routine corporate communication and their potential influence on CE. Design/methodology/approach -The paper reviews past and current literature from which hypothesis are developed. Applying the competing values framework and data from 64 Polish manufacturing firms, we used multiple power regression to test the hypothesized relationships. Findings -The study provides evidence for a positive relationship between routine communication practices and CE. The analysis reveals different levels of influence of various communication aspects on CE. Practical implications -Many organizations' common objective of their redesign efforts is to get rid of the bureaucratic features of the organization. This study suggests that the challenge is to reconfigure certain routine processes and formal requirements within the organization to better suit CE purposes. The paper specifies which routine communication practices can significantly impact CE. Originality/value -Very few prior voices articulate the need of routine practices study in CE research. This paper extends CE theory by providing a new perspective on CE factors and opening new avenues for further research.

Globalisation and digital technology have changed the means and mechanisms of knowledge acquisition. The rapidly expanding open-access online resources and various digital learning platforms present new opportunities in the area of continuous entrepreneurial learning, including that of corporate employees. This paper draws on knowledge spillover theory in order to explore the potential of Massive Open Online Courses (MOOCs) as enablers of knowledge exchange, consolidation and new knowledge creation through connecting geographically and institutionally distant actors. The research design is based on a qualitative interpretative approach exploiting a triangulation of methods by using sets of quantitative data collected from MOOC participants, five focus group interviews and text content of online course discussion groups. This study contributes to our understanding of how digital technologies enable entrepreneurial learning on a massive scale. It identifies three factors which can trigger intense horizontal knowledge spillovers on a massive scale: (i) participants' common interests and aspirations, (ii) induced mobilisation, and (iii) participants' optional anonymity. Additionally, the findings of this study provide useful information for potential MOOC creators regarding the design and delivery of MOOCs targeting a high density of participant interactions.

Objectives: The phenomenon of tocophobia (pathological fear of labor) has not been fully explored. Currently, there are no diagnostic criteria that would enable its detection or make it recognizable as a disease entity. The aim of study was to determine the degree of anxiety/tocophobia as well as to learn about and analyze the causes of this phenomenon in Polish pregnant women. Material and methods:The prospective study included 120 pregnant women in the third trimester of gestation from February to May 2016. The study was performed with the use of a standardized and revised version of the Labor Anxiety Questionnaire (KLP II) designed by Putyński and Paciorek (1997) as well as a proprietary interview questionnaire and structured data documentation form.Results: In 6.7% of the subjects, the level of labor anxiety was very high (> 18 in KLP II). It was the highest in women over 30 years of age (Pearson's chi squared test = 0.00422; p < 0.05). It has been shown that successive childbirths have an impact on the degree of anxiety (p = 0.04217).The highest level of anxiety was noted in primiparous women. In 85% of the subjects, anxiety was caused by fear of labor pain. 56.7% of the tested women did not use any professional help in the preparation for childbirth and motherhood.Conclusions: Primiparas and women over 30 years of age experience very high levels of fear significantly more frequently. The lack of proper preparation for childbirth determines the occurrence of tocophobia. Ante-natal classes and prenatal education based on standards of obstetric care should be promoted in order to reduce or eliminate fear of natural labor.

A B S T R A C T Objective:The aim of the article is to critically review the body of literature exploring the nature and various contexts of EO-firm performance relationship, as well as identify contemporary challenges of this stream of research. Research Design & Methods:The article is an overview of the most important articles of the last two decades of research devoted to EO-firm performance relationship, based on the amount of citation references provided by Ebsco scholar database. The review focuses on: (i) the performance indicators applied in research, (ii) sampling and time frame of the studies as well as (iii) moderating factors of this relationship. Findings: Despite huge progress made, the review reveals important issues that have been side-lined or neglected and remain to be challenged. Implications & Recommendations: This paper presents four major suggestions for a more inclusive, broader stream of research: (i) to take inspiration from stakeholder theory, (ii) to spread the research of EO-firm performance relationship across different entrepreneurship contexts, such as social, non-profit and institutional, adjusting scales and measures, (iii) to apply a more dynamic approach to EO-firm performance relationship, and (iv) to diversify the applied research methods. Contribution & Value Added:The article serves to broaden the scope of EO-firm performance relationship. The discussion presents significant potential contributions brought to EO domain by stakeholder theory. It issues a call to identify and pursue research questions that more effectively address contemporary challenges. Not only does it outline issues and methods worthy of greater attention in future study, but more importantly, leads to extending EO research beyond its current boundaries.

This issue marks another step in our growth as an international journal devoted to entrepreneurship aspects. This thematic issue is titled Advancing Research in Entrepreneurship and consists of nine thematic articles and four nonthematic articles. Interest in entrepreneurship as a field of research does not seize to grow and flourish. Entrepreneurship research covers a very broad set of questions relating to a variety of academic disciplines. Much research still focuses on the heart of entrepreneurship to explain the logic and actions that underline entrepreneurial behaviour. Following Shane and Venkataraman (2000) ground setting paper, some authors claim the existing entrepreneurship research can be best split into two domains: exploration and exploitations of opportunity (Carlsson et al., 2013). In spite of immense progress made, entrepreneurship research still remains much polyphonic and emerging perspectives although have much in common with each other, have largely developed and evolved independently (Fisher, 2012). That is why constant exchange and cooperation between the international community of entrepreneurship scholars is important. EBER hopefully contributes to this much needed exchange. From its launch EBER is dedicated to serve as a broad and unified platform for revealing and spreading economics and management research relating to entrepreneurship. Along the way, we have featured several thematic issue devoted specifically to entrepreneurship. We have tried very hard to keep up with the currents global and local (CEE) developments and challenges hoping that this journal will contribute to finding answers to very pressing questions. Authors have recently identified several fields in entrepreneurship research which remain neglected or underdeveloped. These include interactions between entrepreneurship and different types on institutions, the link between entrepreneurship and human welfare, macroeconomic conditions and the role of entrepreneurship in economic growth (Carlsson et al., 2013), as well as the creation of opportunities through human propensities (Ramoglou & Tsang, 2016) and behavioural entrepreneurship research (Fisher, 2012). There are many calls to introduce more structure and consistent theories on one hand and expansion of behavioural aspects of entrepreneurship research on the other. Scott Shane himself admitted that there is still need "identify errors and confusing points" in entrepreneurship research (Shane, 2012, p. 18). Therefore much remains to be done. In the past much attention has been paid by EBER authors to very current developments in entrepreneurship theory and practice such as international aspects of entrepre
