Streets as new places to bring together both humans and plants: examples from Paris and Montpellier (France)

Greening public city space is a growing issue in France. With examples drawn from Paris and Montpellier, this article seeks to understand what happens when city-dwellers green the public space outside their door and when policies encourage spontaneous flora on the street. Plants were already part of ancient cities and have been a tool for urban planning since the nineteenth century leading to the development of public green spaces and street-tree planting. Urban ecology sparked an interest for spontaneous flora in the 1980s. Public policies concerning water, climate, and biodiversity have been trying to take this unbidden vegetation into consideration since the beginning of this century. Besides, the social sciences have shown that city-dwellers are interested in plants to embellish their balcony, and in city gardens and parks. We tried to find out if this vegetation can be more than just a tool to plan, to green, to bring biodiversity, and to beautify urban space. We argue that letting planted and unbidden flora colonize sidewalks and allowing people to act directly on it brings residents and plants to co-inhabit and co-domesticate the streets, and challenges the timelessness of a city by introducing a life cycle.     

A new Patagonian long-lived species of Cyclochlamys Finlay, 1926 (Bivalvia: Pectinoidea)

Pastorino, G. & Griffin, M., March 2018. A new Patagonian long-lived species of Cyclochlamys (Bivalvia: Pectinoidea). Alcheringa XX, xx–xx.

A new species of the bivalve family Cyclochlamydidae is described from the southwestern Atlantic in Argentine waters. Cyclochlamys argentina sp. nov. is the second representative of the genus known to live in the Magellanic area. In addition, this long-lived species is also recorded from lower Miocene rocks in the province of Santa Cruz exposed along the Atlantic coast of the Monte León National Park. The material was collected from the Punta Entrada Member of the Monte León Formation. These small mollusks clearly belong in Cyclochlamys because of shell characters such as the irregularly pitted prodissoconch I and right valve with commarginally elongated rectangular prisms over most of disc. Cyclochlamys argentina sp. nov. shows affinities with taxa such as C. aupouria and C. shepherdi, all of which are known from areas of New Zealand.

Networks Mobilized to Access Key Resources at Early Stages of Biotech Firms: A Comparative Analysis in Two Moderately Innovative Countries

This paper investigates the networking behaviour of biotechnology start-ups in peripheral locations. The aim is to understand whether the conditions found in this type of environment introduce some specificities in the networking process, namely in network building and early mobilization to access key resources. The paper compares biotechnology start-ups in Portugal and in Southern Italy, focusing on relationships with research organizations and on the relevance assumed by international connections, and investigating the role played by entrepreneurs’ personal networks. The research identified some common features that diverge from the typical biotechnology start-up behaviour and can be regarded as firms’ adaptive responses to the conditions faced. Notwithstanding the frequent presence of close connections with local research organizations—that often play functions that go much beyond that of a knowledge source—the local environment is a lesser determinant for a substantial proportion of firms than would be expected in start-ups. A distinctive feature of these firms is an extensive reliance on foreign sources, for different purposes and from the very early stages. Entrepreneurs’ personal networks are found to be instrumental, both to identify and obtain knowledge in the vicinity and to support the establishment of more complex distant relationships.     

HISTORICAL TRADITIONS OF CIVICNESS AND LOCAL ECONOMIC DEVELOPMENT*

ABSTRACT The paper investigates the importance of history for local economic performance in Italy by studying the role of social capital, which refers to trust, reciprocity and habits of co‐operation that are shared among members of a local community. The paper presents a test based on worker productivity, entrepreneurship, and female labor market participation. Using as instruments regional differences in civic involvement in the late 19th century and local systems of government in the middle ages, it shows that social capital does have economic effects.     

We Branded Ourselves Long Ago: Intangible Cultural Property and Commodification of Fijian Firewalking

ABSTRACT The Fijian firewalking ceremony (vilavilairevo), traditionally performed only by members of the Sawau people on the island of Beqa, is a prime example of a propitiation ritual that has become commodified to suit the requirements of tourism. The Sawau ‘gift’ of walking on white‐hot stones introduces another dimension of the gift practice. Although gifts and commodities are often treated as ideal‐type opposites, and a tradition of Melanesian scholarship has focused attention on the inalienability of gifts, I argue that the self‐consciously traditional firewalking practice of Beqa Island, Fiji, is an inalienable sui generis commodity that becomes effective by ‘branding’ Fijian concepts of different places' distinct custodianships. Over the last two centuries, the gift of firewalking has transmuted itself into a sociocultural tool that has consistently indigenized the power of the foreign. The gift of firewalking has allowed its custodians to locally sustain their community, to gain a reach and respect across the nation and beyond, and to intensify the group's social sentiment and social capital.     

What kind of region reaps the benefits of a currency union?

What is the economic impact of joining a currency union? Is this impact heterogeneous across regions? And how does it change in case of a recession? We answer these questions by investigating the economic impact of joining the euro area for the latecomers, that is, the eastern European countries that adopted the euro after 2002. Differently from previous literature, we use NUTS-2 regions as units of analysis. This novelty allows us to investigate the theoretical predictions of a currency union impact at a more appropriate geographical level. Using a recently developed counterfactual approach, we estimate the overall as well as the disaggregated impact of joining the euro area. We find that the adoption of the euro brought about a small positive effect, which was, however, dampened by the Great Recession. Individual regional estimates suggest heterogeneous returns with benefits accruing mostly to core regions.     

Masonry Italian Code-Conforming Buildings. Part 1: Case Studies and Design Methods

ABSTRACT

Several architectural configurations of unreinforced masonry residential buildings are designed according to the different methods proposed in the Italian code: rules for the so-called simple masonry buildings, linear and nonlinear static analyses. Always complying with code requirements, for each building-site combination, the design was made, as much as possible, without an excessive margin of safety. The different design methods provided buildings with very different levels of safety, being linear static analysis largely overconservative with respect to the nonlinear static approach. These buildings were then analyzed in the companion paper.     

Principal Component Regression in Spatial Lag Model: Teen Employment in the City of Rosario,Argentina

Teen employment is a very important socioeconomic phenomenon because of its consequences on human capital formation. We assess the relation between teen employment and poverty, education, and unemployment in the city of Rosario, using information from the 2010 Argentina Census disaggregated at census block level. We use two different spatial models: The spatial lag model (SLM) and a linear regression model with the spatial component filtered (filtering model, FM). Given the nature of the variables employed, multicollinearity is an issue. One of the techniques proposed in the literature to deal with multicollinearity problems is principal component regression (PCR). We develop an adaptation of such methodology to be used in the SLM. Both models are estimated using their traditional methodologies (instrumental variables for the SLM and OLS for the FM) and using PCR. Although results are similar between the two models, depending on the methodology used in the estimations they differ greatly. Under traditional methodologies estimations show high variability, instability, and contradictory outcomes, but under PCR, results behave according to the literature.     

A Probability-based Approach for the Definition of the Expected Seismic Damage Evaluated with Non-linear Time-History Analyses

The seismic damage evaluated through Nonlinear Time-History Analyses is significantly affected by the response quantity chosen to represent the seismic responses. Starting from the theory of tolerance regions, a generic upper limit of the seismic responses is proposed. The method is applied to a reinforced concrete structure subjected to different record combinations. For each considered damage index and record combination, the upper limit damage is compared with the average value suggested by seismic codes. The proposed method yields a higher seismic damage than the average response and an increase in the damage indices as the number of records decreases.
