Labour supply responses to financial wealth shocks: evidence from Italy
Full text linkWe look at how strongly shocks to wealth affect labour supply, using Italian data. We use asset price shocks to provide a measure of wealth changes that is exogenous to the household's saving and labour supply. Results point to significant effects of wealth on hours of work, whether agents leave their jobs and labour earnings. The magnitude of these effects can be substantial – for example, for individuals who suffered larger wealth losses during the financial crisis. Responses are similar for men and women on average, but older working-age individuals have relatively strong responses that drive the population results. Short-run effects are somewhat persistent
Retirement expectations, pension reforms, and their effect on private wealth accumulation
No full textWe estimate the effect of pension reforms on households’ expectations of retirement outcomes and private wealth accumulation decisions exploiting a decade of intense Italian pension reforms as a source of exogenous variation in expected pension wealth. The Survey of Household Income and Wealth, a large random sample of the Italian population, elicits expectations of the age at which workers expect to retire and of the ratio of pension benefits to pre-retirement income between 1989 and 2002. We find that workers have revised expectations in the direction suggested by the reform and that there is substantial offset between private wealth and perceived pension wealth, particularly by workers that are better informed about their pension wealth

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
BEYOND WATER, Infrastructural Prevention from Flooding
No full textThe aim of this work is to bring together a variety
of data-sets including urban scale plans, data driven
simulations and government regulations related to atflood-
risk areas, in order to develop infrastructural
plans and architectural responses to flooding. In the
field of management and prevention of catastrophic
events, the proposal is to create a telematic map of
risk that brings together data on nature, the built
environment, current policies and forecasting. We
shall reassess the map production so that
environment and risk belong equally to the definition
of 'territory'. In considering the rate of change of
cities and the continuous replacement of the housing
stock, it is necessary to adopt operational plans that
intervene in environmental and infrastructural
planning, architectural project, and ICT systems
design. Only an overall and simultaneous urban vision
and management can bridge the current gaps
between programming documents and executive
plans. Hence the role of the architect is to connect the
different layers of the city, in order to form strategic
planning processes related to the contingencies of a
constantly changing reality. The architecture of the
city, as well as country planning, depends only on
considering the territory as a whole, and maps as the
platform on which it is possible to study future
actions. The main aim of the Telematic Map of the
Risk is to use digital techniques to rematerialize
reality
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
