E.-E. Duvillard de Durand , "Principes et formules du calcul des probabilités pour assigner les limites des variations des événements naturels (1813)", edizione a cura di L. Dell'Aglio e G. Israel, con un saggio introduttivo di L. Dell'Aglio e G. Israel
No full textEmmanuel-Étienne Duvillard de Durand (1755-1832) was known for his actuarial activities and for the construction of life tables, but his contribution to the analysis of social mathematics and the mathematical modelling of mortality long went unrecognized. His attempts to enter the prestigious Académie des Sciences and his ambition to add a probabilistic dimension to population statistics confirm that he was not only a brilliant mathematician, but also a scholar in the noblest sense of the term, to whom this book pays tribute. Principes et Formules du calcul des probabilités pour assigner les limites des variations des événements naturels, a treatise on the «principles and formulae of probability calculation to define the limits of variation in natural events» represents the culmination of his research, recognized in his time by scholars such as Lagrange, Legendre et Laplace, but later condemned to oblivion by the vicissitudes of history and a veritable conspiracy of silence. Duvillard’s previously unpublished work, transcribed and edited for the first time in this book, was written in 1813. Picking up on ideas set forth by the mathematician Jean-Henri Lambert in that same year, he examines mortality with a view to constructing an equation to describe the progressive extinction of a human generation. His work thus represents a turning point in the study of demographic phenomena and a first attempt to apply principles of probability calculation to population science. This is a truly pioneering text which aims to provide an exact evaluation of the limits to be defined when estimating the size of a population. The editors of this treatise – Giorgio Israel, who first uncovered these unpublished archives, and Luca Dell’Aglio – have accomplished a considerable feat. Together, they have patiently deciphered, dissected and transcribed this handwritten text and authored an accompanying essay which places the document in its historical and scientific context. Their work is a historical tribute, aiming to render justice to a man of exceptional qualities by acknowledging his role in the history of science
Notes on the distribution and host plant of Ocladius paucisquamis Meregalli & Colonnelli, 2006 (Curculionidae: Brachycerinae: Erirhinini) in Israel
No full textOcladius paucisquamis Meregalli & Colonnelli, 2006 is an endemic of Israel and Jordan, and the only species of this genus known from Israel so far. The original description states that its distributional range includes the Negev Desert in Israel and southern Jordan. Since 2006, numerous specimens have been collected throughout Israel by us and our colleagues and friends (e.g. Oren Shelef, Elli Groner and Tal Mei-Dan), and now data about its distribution in Israel seem to be quite complete. Ocladius paucisqamis is widely distributed throughout the Negev Desert, from the Southern Coastal Plain to Elat, the Judean Desert, and along the Jordan Valley from the southern Arava Valley, along the coast of the Dead Sea, as far north as Mt. Sartava. It possibly occurs also in the Sinai Peninsula (Egypt), or at least in its northern and eastern parts. This weevil occurs in different types of desert biotopes such as stony desert, sand and loess, dry riverbeds, but never in sandy dunes. During the daytime adults are frequently found under stones, laying on their side and feigning dead, with rostrum and tibia contracted and hidden in special channels of prosternum and femora. Usually two to five individuals occur in close proximity, but sometimes they are found in aggregations of tens of specimens. It is a very common species, albeit rarely observed due to the nocturnal activity of the adults. Specimens have often been found under various Chenopodiaceae (Salsola spp., Haloxylon spp.), as well as under Caryophyllaceae (Gymnocarpos) and Zygophyllaceae (Zygophyllum spp.).

On the homological finiteness properties of some modules over metabelian Lie algebras
No full textWe characterise the modules B of homological type FP,, over a finitely generated Lie algebra L such that L is a split extension of an abelian ideal A and an abelian subalgebra Q and A acts trivially on B. The characterisation is in terms of the invariant A introduced by R. Bryant and J. Groves and is a Lie algebra version of the generalisation (K 4, Conjecture 1] of the still open FPm-Conjecture for metabelian groups [Bi-G, Conjecture p. 367]. The case m = 1 of our main result is treated separately, as there the characterisation is proved without restrictions on the type of the extension.12922123
Organic Hummus in Israel: Global and Local Ingredients and Images
No full textHummus is an ancient traditional dish in Middle Eastern Cultures. In Israel it is one of the most common foods, appropriated as an icon of Israeli culture and nationality. Today, hummus is served in Israel in many restaurants, and is even distributed as a commercially packaged spread sold in supermarkets. Organic hummus – a recent version of the dish – is influenced by global trends of ethical and reflexive food consumption. Organic food is conceived as the 'spearhead' opposing the consequences of globalization. It is customary to view it as representing locality, health, ecology and social justice. But it also embodies representations of globalism and westernism, mainly because of its integration in the global industrial system and its origin among the post-materialistic-social elite in western countries. This article deals with the encounter of the global and the local as embodied in organic hummus in Israel. Looking at the production, distribution, and consumption of this dish uncovers social and political layers embedded in it. I will argue that the global socio-economic conditions and ideas embedded in the concept of organic attached to hummus are the ones which allow – paradoxically – the imagined re-localization of the dish. Organic hummus in Israel is a dish steeped in paradoxical aspects, and therefore characterized by culinary-ideological-dissonance. Hummus is a dish that was perceived as representing rootedness, earthiness, and local simplicity, but nowadays, in its organic version, it wears an economic and symbolic framework of global values used by the Israeli westernizing elite to demonstrate a widespread-environmental cosmopolitan identity.Globalization, Localization, Cosmopolitism, Organic Food, Hummus, Commodification, Israeli Culture
Weak-motion-based attenuation relationships for Israel
No full textWe performed a regional study of earthquake ground motion scaling relations to provide the
seismic hazard community of Israel with a new attenuation relationship that could be used for
the prediction of earthquake-induced ground motion. Strong earthquakes are rather scarce in
Israel and the existing collection of records from strong earthquakes is not sufficient to allowthe
use of traditional regression methods to develop a regional attenuation relationship. We used
velocity seismograms from the Israel Seismic Network to estimate the distance and frequency
dependence of ground motion in the Israel region from frequent, smaller regional earthquakes.
Our analyses included 4814 waveforms recorded by 30 stations of the Israel Seismic Network
from 2000 to 2005. We restricted our analysis to 330 events recorded at five or more stations,
with duration magnitudes ranging between 1.0 and 5.2. We derived empirical excitation,
site and regional attenuation terms by regressing the peak amplitudes of narrowband-filtered
seismograms around the shear wave arrivals and the rms Fourier spectral amplitudes taken
around the specific sampling frequency. In order to optimize the attenuation parameters in our
scaling model, we used a simple grid search. An optimal solution for minimal error between
empirical and theoretical attenuation function was found for the quality parameter Q( f ) = 298 f^0.67 and the geometrical spreading g(r ) parametrized as a bilinear, piecewise function:
r^−0.74 for r ≤ 60 km and r^−0.47 for r > 60 km. The spectral parameters κ of 0.015 s and stress
drop increasing from 0.3 to 4 MPa were used to model the excitation spectra.
A theoretical modelling effort based on Brune’s source spectrum and Random Vibration
Theory (RVT) was performed on the attenuation and source parameters estimated in this study.
Comparison of the attenuation relationship derived with locally measured ground motions
shows excellent agreement with the data in the magnitude range forwhichwe have observations
and seems to be adequate for predictions of earthquake ground motion for the Israel region.
Comparison of Peak Ground Acceleration (PGA) predictions, based on our scaling relationship
with those that have been recently used for seismic hazard analysis in Israel shows that our
attenuation relationship predicts significantly lower ground motions than other relations.Published1127 - 11404.2. TTC - Scenari e mappe di pericolosità sismicaJCR Journalreserve

The Israel-Jordan borderlands in the Arava Valley: differential development and prospects for co-operation
No full textThe area of study extends from south of the Dead Sea to the shores of the Gulf of Aqaba/Eilat. The Arava Valley is divided between Jordan and Israel, having a desert environment marked by high temperatures and low precipitation. The boundary was disputed from 1948 until the Jordanian-Israeli Peace Treaty on the 26th of October 1994. This border situation led to different settlement patterns on either side: the Israeli side was settled with Kibbutzim and Moshavim to secure the borders, whereas the Jordanian side stayed largely untouched because of the extreme conditions. Jordan and Israel share a common hydrogeological system in the Arava Valley, which has not as yet been fully investigated. This will only be possible through transboundary co-operation. Further areas of co-operation include agriculture, infrastructure, industry and tourism. Projects for co-operation in these areas were discussed between the two countries at the Casablanca Summit in October 1994. Each chapter of this thesis analyses the differences and commonalities between the two borderlands in the activities mentioned above, and assesses the prospects for future co-operation. The conclusion compares possibilities for co-operation in the Arava Valley with other selected borderlands in the world where transboundary co-operation already exists. Most cases seem to show that one party is likely to benefit more than the other, at least in the short-term
