Renewed ground uplift at Campi Flegrei caldera (Italy): New insight on magmatic processes and forecast
No full textCampi Flegrei caldera, including the extremely
urbanised city of Naples, is the most risky volcanic area
in the World. The last eruption in the area (1538) occurred
at the end of some decades of ground uplift, superimposed
to secular subsidence. During the last four decades, it
experienced a huge uplift phase, reaching about 3.5 m in
1985, when a subsidence phase started. Recent geodetic
data demonstrate that such a subsidence phase has
terminated, and a new uplift episode started in November
2004, with a low but increasing rate leading to about 0.04 m
of uplift till the end of October 2006. A new indicator, based
on the monitoring of maximum horizontal to vertical
displacement ratio with continuous GPS, indicates that
this uplift is likely to be associated with input of magmatic
fluids from a shallow magma chamber. The method is
promising to monitor magma intrusion processes, at this and
other volcanoes. Citation: Troise, C., G. De Natale, F. Pingue,

Full text linkA solution for the chicken and egg paradox in taxi e-hailing platforms: some evidence from the MyTaxi – FreeNow case
No full textPurpose: This study aims to explore the chicken and egg paradox in the taxi e-hailing business contributing to define a condition of system emergence. This paradox is a meaningful one as these platforms represent a system where the passengers systems have no reason to participate if they have no drivers-systems to answer their call, but, at the same time, the platform is not useful to the drivers-system if there are no passengers-systems using the platform. Design/methodology/approach: To understand how this paradox has been dealt with in the taxi e-hailing business, this study focused on a case study on a best practice in Italian taxi e-hailing industry (i.e. MyTaxi/FreeNow). This study wants to comprehend which actions have been implemented to solve this paradox and has tried to identify the interconnections between the various strategies to create a closed loop diagram for further testing. Findings: This study has found that the company did not choose a single “subsystem” (passenger or driver), but it has stimulated the creation of several mutually reinforcing motivation for have both subsystems interact to help the company grow. Originality/value: To the best of the authors’ knowledge, this paradox has never been studied using the complex adaptive system perspective. This perspective is particularly useful in this case and in the similar ones with several different interacting factors that cannot be really studied without using a higher order perspective
Investigating the impact of multidimensional social capital on equity crowdfunding performance
No full textThis research explores how social capital, in the multidimensional perspective using cognitive, relational and structural dimensions influences equity-crowdfunding (ECF) performance considering both the number of investors engaged and the funds collected. Our results demonstrate that cognitive dimensions in part affects ECF performance, in fact shared meaning has a little positive impact on both funding collected and the number of investors, while shared language has a negative effect on the investors involved. Both obligation and trustworthiness (relational dimension) positively influence ECF performance. Regarding the structural dimension, social network ties has positive effects on ECF performance, while social interactions has a positive impact on funding collected. The research contributes to the current literature on ECF and highlights new factors affecting ECF performance. The study has implications from both a theoretical and a practical perspective. The study findings will be relevant for entrepreneurs, platforms managers and policymakers and offers avenues for further research
