Integrating Entrepreneurship into the Design Classroom: Case Studies from the Developing World
© 2017, Springer Science+Business Media, LLC. Developing countries are more and more committed to building a knowledge-based economy as a means to diversify from their current resource-based economy. The current focus of many governments is on technology with real insights on creative economy and arts. In this context, universities are seen as a key partner of the government. This article presents the results of two innovative case studies of professors working in the College of Art and Design collaborating with a professor in the College of Business to integrate the concepts of entrepreneurship into their interior design courses. This was done through designing space for entrepreneurial projects and by the students acting as entrepreneurs themselves with an external client. This dual model of training combines (1) learning processes about the habits and the needs of entrepreneurs and (2) learning by acting as an entrepreneur. Such methods demonstrate the role of universities to provide a proper theoretical background for students and to foster entrepreneurial behaviors through arts entrepreneurship education. Furthermore, the central role of professors to introduce innovative teaching methods to combine entrepreneurship and the creative economy into non-business courses is an important finding in these case studies

Evaluation of shallow landslide-triggering scenarios through a physically based approach: an example of application in the southern Messina area (northeastern Sicily, Italy)
Rainfall-induced shallow landslides are a widespread phenomenon that
frequently causes substantial damage to property, as well as numerous
casualties. In recent~years a wide range of physically based models have been
developed to analyze the triggering process of these events. Specifically,
in this paper we propose an approach for the evaluation of different shallow
landslide-triggering scenarios by means of the TRIGRS (transient rainfall infiltration and
grid-based slope stability) numerical model. For the
validation of the model, a back analysis of the landslide event that occurred in
the study area (located SW of Messina, northeastern Sicily, Italy) on 1
October 2009 was performed, by using different methods and techniques for
the definition of the input parameters. After evaluating the reliability of
the model through comparison with the 2009 landslide inventory,
different triggering scenarios were defined using rainfall values derived
from the rainfall probability curves, reconstructed on the basis of daily
and hourly historical rainfall data. The results emphasize how these
phenomena are likely to occur in the area, given that even short-duration
(1–3 h) rainfall events with a relatively low return period (e.g.,
10–20~years) can trigger numerous slope failures. Furthermore, for the same
rainfall amount, the daily simulations underestimate the instability
conditions. The high susceptibility of this area to shallow landslides is
testified by the high number of landslide/flood events that have occurred in the past
and are summarized in this paper by means of archival research. Considering
the main features of the proposed approach, the authors suggest that this
methodology could be applied to different areas, even for the development of
landslide early warning systems
Validation of a shallow landslide susceptibility analysis through a real case study. An example of application in Rome (Italy)
In the last years, statistically based models (such as Logistic Regression) have been frequently used for evaluating the probability of landslide occurrence over large areas. In the case of Rome, over the years, more than 348 landslides have been recorded throughout the city. For this reason, in this study, we implemented and evaluated three main validation criteria of logistic regression to assess the rainfall-induced landslide susceptibility in a specific area of the city of Rome. Through the evaluation of the predictive performances, the best model has been identified and the results were also compared with those obtained in similar case studies
The role of initial soil conditions in shallow landslide triggering. Insights from physically based approaches
In the last years, the shallow landslide phenomenon has increasingly been investigated through physically based models, which try to extend over large-area simplified slope stability analyses using physical and mechanical parameters of the involved material. However, the parameterization of such models is usually challenging even at the slope scale, due to the numerous parameters involved in the failure mechanism. In particular, considering the scale of the phenomenon, the role of transient hydrology is essential. For this reason, in this work we present the outcome of different experimental tests conducted on a soil slope model with a sloping flume. The tested material was sampled on Monte Mario Hill (Rome, Central Italy), an area which has been frequently affected by rainfall-induced landslide events in the past. In this respect, we also performed a physically based numerical analysis at the field conditions, in order to evaluate the response of the terrain to a recent extreme rainfall event. The results of the flume tests show that, for the same material, two different triggering mechanisms (i.e., uprise of a temporary water table and advance of the wetting front) occur by varying the initial water content only. At the same time, the results of the numerical simulations indicate that clayey sand and lean clay are the soil types mostly influenced by the abovementioned rainfall event, since the initial moisture conditions enhance the formation of a wide wetting front within the soil profile
The potential of spatial statistics for the reconstruction of a subsoil model. A case study for the Firenze-Prato-Pistoia Basin, Central Italy
A reliable subsoil model represents the first step in assessing potential geological hazards and adopting proper mitigation measures accordingly. However, one of the main difficulties related to the definition of such models concerns the extrapolation of single-point data over wide, uninvestigated areas. For this reason, in this work, we reconstruct a subsoil model within an alluvial basin through a methodology specifically based on spatial-statistical analyses of geophysical in situ point measurements. In particular, measurements of ambient noise were analysed and extrapolated to obtain a spatially continuous distribution of fundamental resonance frequency (f0) over the entire basin. Local portions of the basin were then defined according to a specific relationship between f0 and the minimum distance from the bedrock outcrops (MDBO). This analysis revealed how the position of the identified clusters is consistent with the asymmetric geometry of the basin. The resulting simplified subsoil model was then validated through additional experimental measurements of ambient noise to evaluate the reliability of the proposed methodology. As the test site, we selected the Firenze-Prato-Pistoia Basin (Tuscany region, central Italy), where more than two hundred homogeneously distributed noise measurements were collected from previous seismic microzonation investigations

Sediment texture in rock avalanche deposits. Insights from field and experimental observations
Sedimentary structures within rock avalanche deposits have gained increasing attention in recent years, since they may provide useful information about the dynamics of such energetic events. This work then is aimed at better defining the physical processes arising during the propagation, paying particular attention to the kinetic sieving mechanism, and strengthening the assumption (widely diffused in the literature) that such a process does not occur for similar events. Specifically, after the examination of two rock avalanche deposits in Central Italy, where cuts through the fragmented deposits are accessible and illustrative of the sediment texture, a series of laboratory flume tests have been performed in order to investigate in detail the flowing process. A simplified physical model for granular agitation has been then introduced to explain how and why kinetic sieving may occur at the laboratory scale and, in the case of natural granular flows of reduced size, also at the field scale
A web-based GIS (web-GIS) database of the scientific articles on earthquake-triggered landslides
Over the last 2 decades, the topic of
earthquake-triggered landslides (EQTLs) has shown increasing relevance in
the scientific community. This interest is confirmed by the numerous
articles published in international, peer-reviewed journals. In this
work we present a database containing a selection of articles published on
this topic from 1984 to 2021. The articles were selected through a
systematic search on the Clarivate™ Web of Science™ Core
Collection online platform and were catalogued into a web-based GIS (web-GIS),
which was specifically designed to show different types of information.
After a general analysis of the database, for each article the following aspects were identified:
the bibliometric information (e.g. author(s), title, publication year), the
relevant topic and sub-topic category (or categories), and the earthquake(s) addressed. The
analysis allowed us to infer general information and statistics on EQTLs (e.g.
relevant methodological approaches over time and in relation to the scale of
investigation, most studied events), which can be useful to obtain a spatial
distribution of the articles and a general overview of the topic.</p
