Abstract
Web 4.0 is a new evolution of the Web paradigm based on multiple models, technologies and social relationships. The concept of Web 4.0 is not totally clear and unanimous in literature, because it is composed by several dimensions. In this sense, this study uses a systematic review approach to clarify the concept of Web 4.0 and explore its various dimensions, analyzing if they have elements in common. The findings indicate that the number of studies published from 2009 to 2017 on this field significantly increased, having reached a peak in 2014. Furthermore, we identified five dimensions associated with the Web 4.0 paradigm, in which the terms “pervasive computing” and “ubiquitous computing” are the most widely used in the literature. On the other side, terms such as “Web 4.0”, “symbiotic Web” and “Web social computing” are not often used.

Abstract
Entrepreneurs are critical for countries' industrial dynamics and economic growth. Although there are several studies focusing on the attitudes, cognitions and traits of entrepreneurs, only a few have explored the link between entrepreneurship and the job features entrepreneurs most value in the work setting. Taking a longitudinal perspective, over two periods of time, 1990-1993 and 2008-2010, the present study resorted to the European Value Study dataset, encompassing 27 European countries and more than 100 thousand individuals. Based on logistic estimates, we found that, compared with non-entrepreneurs, entrepreneurs consider work more important than other life dimensions (except family). Moreover, some work values associated with entrepreneurship (e.g., use initiative, achieving something, responsible job, meeting abilities, have a say, and learning new skills) are indeed mentioned the most by entrepreneurs and emerged significantly related with entrepreneurial propensity. Finally, some work values (e.g., have a say) are associated with entrepreneurship propensity regardless of country's culture, whereas others (e.g., interesting job) are strongly influenced by culture.

Abstract
Purpose - The purpose of this paper is to analyze the aftermath of business failure (BF) by addressing: how the individual progressed and developed new ventures, how individuals changed business behaviors and practices in light of a failure, and what was the effect of previous failure on the individual's decisions to embark on subsequent ventures. Design/methodology/approach - The authors resort to qualitative methods to understand the aftermath of BF from a retrospective point of a successful entrepreneur. Specifically, the authors undertook semi-structured interviews to six entrepreneurs, three from the north of Europe and three from the south and use interpretative phenomenological analysis. Findings - The authors found that previous failure impacted individuals strongly, being shaped by the individual's experience and age, and their perception of blame for the failure. An array of moderator costs was identified, ranging from antecedents to institutions that were present in the individual's lives. The outcomes are directly relatable to the failed experience by the individual. The authors also found that the failure had a significant effect on the individual's career path. Originality/value - While predicting the failure of healthy firms or the discovery of the main determinants that lead to such an event have received increasingly more attention in the last two decades, the focus on the consequences of BF is still lagging behind. The present study fills this gap by analyzing the aftermath of BF.

Abstract
Population ageing and its influence on the economic growth has long been the focus of major concern. Using bibliometric techniques we found that: (1) although ageing has increasingly attracted more researchers within economics literature, the relative weight of ageing and economic growth related papers does not evidence a clear positive trend; (2) recent studies reveal the willingness of researchers to evaluate less immediate mechanisms relating ageing and economic growth; (3) the increase in the use of empirical methods reflects a trend to test economic phenomena with real-world data against the theory; (4) very few studies focus on developing and less developed countries.
