Impact of Trade Area Environment on Bank’s Comparative Advantages
2004
This paper analyzes the relationship between the comparative advantages of bank branches and the trade area environment. Bank branches are points of sale whose trade environment influences their activities and performance. Comparative advantages are defined, for each output mix, by the strict dominance of a production technology in a specific trade area over the production technologies of other environments. Using Shephard’s output distance functions on a sample of 728 bank branches, we compare the production technologies for different output mixes and different trade environments. We show that none of the production technologies strictly dominates the others and none of them is strictly do…
Characterisation of clayey raw materials for ceramic manufacture in ancient Sicily
2011
Abstract It is well known that mineralogical, petrographic and chemical analyses can successfully support provenance studies of archaeological ceramics. The characterisation of a ceramic paste, the assessment of its technology of production and its provenance assignment related to a specific production centre or to a geographical and/or compositional space, are all tasks that can be performed even more accurately if the clayey raw materials used in pottery production are also studied. For that reason the identification of the clay deposits exploited in a given ceramic workshop often plays a key role in the archaeometric reconstruction of the production cycle where geology, mineralogy, petro…
Failures (with some successes) of assisted reproduction and gamete donation programs
2013
Although the possibilities for the treatment of infertility have been improved tremendously, not every couple will be treated successfully.Crude overall pregnancy rates of 50-65% per patient can be achieved nowadays, irrespective of the type of profertility treatment applied first.IVF only accounts for about 20% of the pregnancies achieved. Dropout is an important reason for not reaching the estimated pregnancy rate. Even after failed IVF, spontaneous pregnancies do occur. Sperm and oocyte donation (OD) offer additional chances to subfertile couples. Severity of the male factor (in sperm donation) and young donor age (in OD) are important determinants of success.Analysis of assisted reprodu…
Study of archaeological ceramics from northern Bactria in Late Antiquity and Early Middle Ages (3rd-7th centuries AD)
2023
Esta tesis se centra en el análisis arqueológico y arqueométrico de cerámicas kusháno-sasánidas (ss. III-IV d.C.) y altomedievales (ss. V-VIII d.C.) procedentes de diferentes yacimientos localizados en el sector septentrional de la antigua Bactriana (Asia Central). Bactriana, o Tokharistán, como fue llamada desde finales del siglo IV d.C. (Litvinsky, 1998), fue una de las satrapías del Imperio Aqueménida que incluía los territorios al norte y al sur del antiguo río Oxus (ahora Amu Darya), actualmente correspondientes al sur de Uzbekistán, sur de Tayikistán y norte de Afganistán. La región se caracterizó por contactos continuos entre pueblos, debidos a migraciones, invasiones y comercio. Des…
