A novel dataset on legal traditions, their determinants, and their economic role in 155 transplants
No full textAbstractThe law and the economy are deeply influenced by the legal tradition or origin, which is the bundle of institutions shaping lawmaking and dispute adjudication. The two principal legal traditions, common law and civil law, have been transplanted through colonization and occupation to the vast majority of the jurisdictions in the world by a group of European countries. Here, I illustrate a novel dataset recording the lawmaking institution employed by 155 of these jurisdictions at independence and in 2000 and four discretion-curbing adjudication institutions adopted by 99 of these “transplants” at the same two points in time. Contrary to the “legal origins” scholars׳ assumption, 25 transplants changed the transplanted lawmaking institution and 95 modified at least one of the transplanted lawmaking and adjudication rules. In “Endogenous Legal Traditions” (Guerriero, 2016a) [12], I document that these reforms are consistent with a model of the design of legal institutions by societies heterogeneous in their endowment of both the extent of cultural heterogeneity and the quality of the political process. In “Endogenous Legal Traditions and Economic Outcomes” (Guerriero, 2016b) [13] moreover, I show the relevance of considering legal evolution and the endogeneity between legal traditions and economics outcomes. The data illustrated here also include the proxies for the determinants of legal evolution I use in “Endogenous Legal Traditions” (Guerriero, 2016a) [12] and the novel measure of economic outcomes I employ in “Endogenous Legal Traditions and Economic Outcomes” (Guerriero, 2016b) [13]
A novel dataset on horizontal property rights in 126 jurisdictions
No full textThe law and the economy are deeply influenced by horizontal property rights, which are the rules regulating legal direct and indirect takings between private parties. To foster research on the determinants and impact of these institutions, we illustrate here a novel data set partially employed in (Dari-Mattiacci, Giuseppe, Carmine Guerriero, 2015; Dari-Mattiacci, Giuseppe, Carmine Guerriero, Zhenxing Huang, 2016) [3,4], and (Guerriero Carmine, 2016) [6] and describing the acquisition of ownership through adverse possession of personal and real property and the use of government takings to transfer real property from a private party to another private party in 126 jurisdictions. These data are based on the laws and judicial decisions prevailing in each jurisdiction between 1981 and 2011
Interaction of nano-sized nutrients with plant biomass: a review
No full textPlant lignocellulosic biomass is an important natural resource providing (macro) molecules of industrial relevance (e.g. cell wall polysaccharides, secondary metabolites, sugars), as well as wood (Guerriero et al. 2014, 2016b). The synthesis of plant biomass depends, among other factors (e.g. light availability, photoperiod, temperature), on soil nutrient availability (Chatzistathis and Therios 2013), and the effects on plant cell wall synthesis can be quite strong in the case of both macro- and micronutrient deficiencies. The impact of nanotechnology on agriculture has been a real revolution, an inspiration for innovative approaches, but also a source of controversies ( vide infra ). The exploitation of the wall pores of plant cells is at the base of nutrient nano-delivery (Liu and Lal 2015); despite the great potential of this innovation in agriculture, a thorough understanding of the relationship nanofertilizers/plants is still lacking.
Plant lignocellulosic biomass is a renewable resource which provides wood, a major commodity for mankind, as well as molecules used as building blocks in chemical industry.
It is known that nutrition impacts plant biomass production, by acting, either directly or indirectly, on cell wall-associated processes. Well-documented are the roles of both macro- and micronutrients on plant growth and development. Nanotechnology has given a new impetus to agriculture: several studies have indeed published the effects of nano-sized nutrients/nanoparticles on plants. We here review the published literature on the effects of nano-sized nutrients on plants, by adopting, when documented, a cell wall perspective, and we underline both the positive and negative aspects

Giulio II
Il Papa guerriero e mecenate: i due volti del Rinascimento
Massimo Rospocher in questo dvd ci presenta Papa Giulio II.
Come sovrano pontefice, politico spregiudicato e sommo mecenate, Giulio II rimane uno dei personaggi che maggiormente condizionano l'immaginario collettivo del Rinascimento. Ma quale fu l'immagine che ne ebbero i contemporanei - non solo gli uomini di lettere, i prelati e i professionisti della politica, ma anche il popolo urbano del primo Cinquecento? Questo libro risponde a tale domanda ricostruendo l'immagine di Giulio II nella sfera pubblica e nella comunicazione politica in vari contesti italiani ed europei (Bologna, Ferrara, Roma, Venezia, Londra e Parigi). Intrecciando i racconti dei cantastorie con i dispacci dei diplomatici, le voci e le canzoni di piazza con i trattati degli umanisti, Rospocher delinea un ritratto inedito del "papa guerriero", una rappresentazione in perenne oscillazione tra laude e vituperio, tra guerra e beatitudine
The warrior and the sword: cultural, symbolic and literary routes between french and japanese Middle Ages
No full textopenL’obiettivo delle seguenti pagine sarà di rintracciare delle corrispondenze transculturali nel rapporto tra un guerriero e la propria arma. Più nello specifico, concentrandosi sul cavaliere dell’area franca del basso medioevo, e nel samurai giapponese; e concentrandosi sull’arma prediletta, la spada.
Si vorrà evidenziare come, seppur a grande distanza geografica, esistono dei punti di contatto tra le due culture, e specialmente sui miti ed i simboli che ciascuna ha elaborato, inerenti al rapporto tra il guerriero e l’arma.
Nella prima sezione si tratta del mondo occidentale, partendo dagli studi di storia medievale, si traccia una breve storia della figura del cavaliere e del concetto di “cavalleria”; dal punto di vista militare e sociale. Successivamente, si approfondisce il suo equipaggiamento; trattando infine dell’importanza peculiare della spada, in quanto arma e in quanto simbolo.
Segue poi un paragrafo dedicato ai raffronti testuali di area romanza a confermare le informazioni enunciate, sia su testi mitologici che cavallereschi in pieno, come nel caso di Chretiene de Troyes
Climate variations and crop yields: a sustainability issue illustrated by a case study from the Abruzzo region, Italy
No full textClimate variations, of short- and long-term, pose a major sustainability challenge, with potential farreaching
economic and social impacts, including fluctuations in agricultural yields and subsequent volatility
in prices and the availability to populations of essential food resources. To investigate the effects of short- and
long-term climate variation on crop yields, the four provinces of the Abruzzo region, in central Italy, were
studied in terms of temperature, precipitation and agricultural yields of wheat, olive and grape.
This study illustrates a detailed statistical analysis involving climatic variables and crop yields over the
time range 1952-2014, at a provincial scale in the Abruzzo Region. To individuate variations in the correlation
between agricultural production and climatic condition over time, the statistical correlation was analyzed
between indices, such as standardized precipitation indexes (SPI and SPEI) calculated over different months
of the year, with the oscillations of crop yield around the trend, described by standardized residual yield series
(Guerriero et al., 2023). Such correlation has been calculated for several time windows, each of thirty years
wide, over the time range 1952-2014.
The results are summarized as follows:
– In the studied provinces, the maximum and minimum daily temperatures show variation in the trend over
the past 60 years;
– In the studied provinces, climate is moving from temperate towards temperate-arid, with an increase in
drought intensity and persistence, starting from the 1980s;
– The correlation analysis highlighted an increase in correlation between crop yield and climatic fluctuations,
over the past 60 years. Such rise can be interpreted as an increasing sensitivity of the agricultural production
system to climate fluctuations, over time.
Although the considered agricultural production system exhibits a progressive yield growth, an increase
in correlation between production and climatic fluctuations highlights, on the one hand, an inability of the
system itself to maintain high performance even in unfavorable climatic conditions. On the other hand, yield
fluctuations (even positive ones) always represent a potential disturbing element of related market equilibria
