Relative social status and conformism: Experimental evidence on local public good contributions
No full textThrough an artefactual field experiment conducted in Colombia, where participants make repeated contributions to a local natural conservation project, I test a novel way to identify high status individuals within a community, and show that status, so defined, is correlated with public good giving. Both absolute and relative status have a statistically significant and economically relevant influence on behavior. In particular, the same individual, when matched with a lower status partner, donates more and conforms less to the partner's action. The results indicate that contributions to local public goods can be enhanced by interventions that make relative status more salient
Motivation crowding in environmental protection: Evidence from an artefactual field experiment
Full text linkThis paper examines how motivation, crowding and social image affect environmental conservation decisions. An artefactual field experiment conducted in Bolivia is used to reproduce the trade-off between individual and social benefits in natural resource use and test the effect of non-monetary and non-regulatory incentives on pro-social behavior for environmental conservation. The results show the presence of a social norm prescribing positive contribution towards environmental protection, and that external incentives have heterogeneous effects on pro-social behavior depending on how they influence reputation and self-image. The experimental results differ from those of analogous experiments conducted in the laboratory, and are instead consistent with those from field experiments on common-pool resource management. This fact suggests caution in generalizing conclusions, reached in the laboratory, to different settings and populations. © 2011 Elsevier B.V
Determinants of conservation among the rural poor: A charitable contribution experiment
Full text linkThis paper examines how conservation decisions are affected by environmental degradation. Donations to an environmental NGO and participation in actual conservation activities capture individual preferences for environmental conservation. Environmental degradation is measured both through survey-based data on experiences of deforestation and environmental shocks, and through indices of deforestation constructed with GIS data. The results show that being exposed to environmental degradation is correlated both with higher donations and conservation behavior. The relationship between conservation choices and individual social preferences is also explored. Experimental measures of individual altruism and inequality aversion, and survey measures of trust, time preferences and civic engagement are correlated with donations and real world conservation decisions respectively. These findings show the role of environmental awareness in fostering environmental conservation even in very poor settings. They also highlight the potential of experiments, which closely mirror real world decisions, to generate conclusions generalizable to individual behavior outside the laboratory. © 2014
Social preferences and environmental quality : Evidence from school children in Sierra Leone
Full text linkThis article examines the effect of exogenous health shocks in utero and in infancy on the development of social preferences later in childhood. We use data from binarychoice dictator games run with school children in rural Sierra Leone to measure aversion to inequality, altruism and spite towards peers within and outside one's social group. We exploit shocks in the level of rainfall in the place and year of children's birth as sources of variation in the environment at the time children are born. We find that being born into an environment with higher rainfall, which is associated with worse health outcomes, lowers the probability that a child will demonstrate a propensity to maximise her own material pay-off. We show that rainfall shocks are linked to children's height-for-age and suggest that they influence preferences through their effect on children's health. Whether the relationship is a direct one from health to physical and cognitive development, or an indirect one through parents' socialisation, our results suggest that preferences are shaped by features of the physical environment in which individuals are born.</p
E-campaigning on Twitter: The effectiveness of distributive promises and negative campaign in the 2013 Italian election
No full textRecent studies investigated the effect of e-campaigning on the electoral performance. However, little attention has been paid to the content of e-campaigning. Given that political parties broadcast minute-by-minute the campaign messages on social media, this comprehensive and unmediated information can be useful to evaluate the impact of different electoral strategies. Accordingly, this article examines the electoral campaign for the 2013 Italian general election to assess the effectiveness of positive and negative campaigning messages, measured through content analysis of information published on the official Twitter accounts of Italian parties. We evaluate their impact on the share of unsolicited voting intentions expressed on Twitter, measured through an innovative technique of sentiment analysis. Our results show that negative campaign has positive effects and its impact is stronger when the attacker is meanwhile under attack. Conversely, we only find a circumstantial effect of positive campaign related to clientelistic and distributive appeals
Historical legacy and policy effectiveness: The long-term influence of preunification borders in Italy
Full text linkThis paper investigates the interplay between cultural traditions and policy effectiveness. It explores the differential impact of a large development program (Cassa per il Mezzogiorno), implemented for four decades, starting in the 1950s, to stimulate convergence between Italy's south and the more developed north, on municipalities with different histories. Namely, we consider a sample of municipalities located on either side of the historical border of the Kingdom of the Two Sicilies, whose legacy is considered, from Putnam onwards, to be a prime-facie cause of Southern Italy's underdevelopment. Having been part of the Kingdom of the Two Sicilies is associated with a negative impact of development policies, but only when the allocation of development funds through the Cassa per il Mezzogiorno suffered from low quality of governance and was driven by political considerations rather than by efficiency ones
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
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
