Sull'organizzazione sociale tradizionale dei Borana: Contributo al dibattito

1988

This article deals with the traditional social organization of the Borana, an Oromo-speaking pastoral group of Northern Kenya and Southern Ethiopia. A special attention is reserved to the political role of four basic institutions: the kinship system, the gadaa system, the hariyaa system and the qaalluu. Cet article concerne l'organisation sociale des Borana, un groupe pastoral de langue Oromo du Kenya septentrional et de l'Ethiopie méridionale. Une attention particulière est portée au rôle politique de quatre institutions fondamentales: le système de parenté, les systèmes gadaa et hariyaa, et le qaalluu.

Sviluppo partecipante e sistemi tradizionali: Il caso dei Borana dell'Etiopia

1992

In the development programs concerning the Ethiopian Borana local groups are assigned the role of principal group for development initiatives. As such, the project seems to meet the principle of participatory development. However, among the Borana, local communities have very little organizational significance and no say at all on matters regarding rights of property. Such authority is instead attributed to descent groups, which are not localized. In particular, clans have both the organizational capacity to coordinate collective investments on natural resources and the authority to guarantee personal and collective property rights. It is therefore suggested that a direct link with clans an…

Il caso Diigalu Tiiti. Strutture sociali e processi produttivi presso i Borana dell'Etiopia

1990

This paper concerns the social elements which are relevant in relation with some important productive features of the Borana of Southern Ethiopia. Recent field-data seem to indicate that the structure provided by descent is particularly significant with regard both to economical mutual assistance and to management of wells, the crucial natural resources. Cet article concerne les éléments sociaux importants par rapport à des procédés de production des Borana du sud de l'Ethiopie. Le système de parenté semble particulièrement significatif aussi bien en ce qui concerne l'assistance réciproque que pour la gestion des puits, la ressource naturelle cruciale.

«Perché l’intelletto abbia respiro e la giustizia abbia il suo corso». La testimonianza civile di Giuseppe Antonio Borgese

2021

Nel gennaio del 1935, sul periodico antifascista «Giustizia e Libertà» approdano alla luce editoriale le due lettere indirizzate da Borgese a Mussolini, il 18 agosto del 1933 e il 18 ottobre del 1934, in cui prende corpo la testimonianza del dissenso dell’intellettuale, già dal 1931 trasferitosi in America, rispetto alla deriva autocratica del regime in Italia. Il discorso epistolare, mosso dalla volontà di esprimere il diniego all’imposizione del giuramento fascista agli intellettuali e strategicamente ignorato da Mussolini, giunge, nella seconda lettera del ’34, alla definitiva frattura dal fascismo cui si oppone la «libera unione degli stati d’Europa», un disegno civico coltivato nel tem…

Synthesis and coordinating ability of an anionic cobaltabisdicarbollide ligand geometrically analogous to BINAP.

2004

The anionic chelating ligand [1,1'-(PPh 2 ) 2 -3,3'-Co(1,2-C 2 B 9 H 1 0 ) 2 ] - has been synthesized from [3,3'-Co(1,2-C 2 B 4 H 1 1 ) 2 ] - in very good yield in a one-pot process with an easy work-up procedure. The coordinating ability of this ligand has been studied with Group 11 metal ions (Ag, Au) and with transition-metal ions (Pd, Rh). The two dicarbollide halves of the [1,1'-(PPh 2 ) 2 -3,3'-Co(1,2-C 2 B 9 H 1 0 ) 2 ] - ligand can swing about one axis in a manner analogous to the constituent parts of BINAP and ferrocenyl phosphine derivatives. All these ligands function as hinges, with the most important property in relation to the coordination requirements of the metal being the P…

Synthesis and fluorescence emission of neutral and anionic di- and tetra-carboranyl compounds

2011

A new family of photoluminescent neutral and anionic di-carboranyl and tetra-carboranyl derivatives have been synthesized and characterized. The reaction of α,α'-bis(3,5-bis(bromomethyl)phenoxy-m-xylene with 4 equiv. of the monolithium salt of 1-Ph-1,2-C(2)B(10)H(11) or 1-Me-1,2-C(2)B(10)H(11) gives the neutral tetracarboranyl-functionalized aryl ether derivatives closo-1 and closo-2, respectively. The addition of the monolithium salt of 1-Ph-1,2-closo-C(2)B(10)H(11) to α,α,'-dibromo-m-xylene or 2,6-dibromomethyl-pyridine gives the corresponding di-carboranyl derivatives closo-3 and closo-4. These compounds, which contain four or two closo clusters, were degraded using the classical method,…

Ocher and cinnabar in the argaric funerary record

2012

The known cases of Bronze Age Argaric stained skeletons found in the Southeast of the Iberian Peninsula, have been analysed. The various hypotheses proposed relating to the origin of these colorations have been evaluated in light of new data provided by SEM, XRD and RAMAN spectroscopic analysis carried out on five Argaric graves of Murcia and Alicante. The results have indicated the presence of ochre and cinnabar on some of the skeletons. Without discarding the possibility that both substances were used in dyeing fabrics, it is proposed that their main use was for face and body make-up, being higher the number of recorded cases on female skeletons compared to male.

Inhalation solutions: which one are allowed to be mixed? Physico-chemical compatibility of drug solutions in nebulizers.

2006

AbstractTherapy of chronic respiratory diseases often involves inhalation therapy with nebulizers. Patients often attempt to shorten the time consuming administration procedure by mixing drug solutions/suspensions for simultaneous inhalation. This article considers the issue of physico-chemical compatibility of admixtures of drug solutions/suspensions in nebulizers.A search of databases, prescribing information and primary literature was conducted to locate literature concerning the physico-chemical compatibility of inhalation solutions/suspensions. This was supplemented by telephone interviews.Admixtures of albuterol with ipratropium and/or cromolyn, of albuterol and budesonide, or tobramy…
