Where Economics Has Been Headed? Multiple Identities And Diversity In Economic Literature Evidence From Top Journals Over The Period 2000-2006 A First Note

This short paper presents some preliminary results of an ongoing research work focusing on richness and diversity of economic literature. The key idea is that each article published in an economic journal retains multiple identities. These multiple identities are captured through the use of Jel codes. A sample of ten top generalist journals has been selected. The relative abundance of all Jel categories has been computed for the period 2000-2006. Moreover, a degree of diversity has been proposed for both the sampled journals and the entire Econlit database.JEL; Econlit; Economic Journals; multiple identities; identity; relative abundance; diversity; evenness; richness

Resistance to frost and tuber soft rot in near-pentaploid Solanum tuberosum - S. commersonii hybrids

The objectives of the present study were to evaluate the tolerance to low temperatures and tuber soft rot in sexual near-pentaploid hybrids between incongruent 2x (1EBN) Solanum commersonii (CMM) and 4x (4EBN) S. tuberosum (TBR). For freezing resistance, killing temperatures both under non-acclimated and un- der acclimated conditions were determined using the ion leakage procedure. Values for the hybrids were dis- tributed between the wild and cultivated parental values. Some hybrids displayed an acclimation capacity close to 2.5°C, typical of hardy species. Artificial inoculation of tubers with Pectobacterium carotovorum ssp. carotovorum (formerly Erwinia carotovora ssp. carotovora) provided evidence of variability in disease response. Highly resistant hybrids were identified. After conventional phenotypic selection, wild genome content was estimated based on the presence of CMM-specific AFLP fragments. Seven primer combinations were used (Eco-AGG/Mse-CAA; Eco-ACC/Mse-CAT; Eco-ACT/Mse-CAC; Eco-ACT/Mse-CAG; Eco- ACT/Mse-CAA; Eco-ACT/Mse-CAT; Eco-AGG/Mse-CAG). The percentages of CMM-specific AFLPs ranged from 4.3% to 56.7%, with an average value of 28.1%. AFLP analysis was employed for the selection of the hybrids to be used for further breeding objectives

Sistemi di trasporto pubblico urbano via mare. Un modo per rilanciare il waterfront di Palermo

New sea transport terminals can be major people movers and main centres for various urban activities and functions, determining strong social output. The city of Palermo qualifies as a prominent research territory, due to its densely urbanized and populated waterfront areas, associated with a lack of transport infrastructures and efficient transit systems to meet the mobility demand of residents and commuters. A new waterfront arrangement can improve the city image and opens the way to new urban public transport systems by sea, like ferries and hydrofoils, as an alternative to the conventional land transit systems already affected by unavoidable congestion. Plans to link by sea different destination on the coast, should first identify and locate the several historical docking points of the city, as they will be the connections between the land transit systems and the sea. Local cultural heritage, handicraft, architecture and natural aspects, can be attractions for the sea transit users, occasional visitors, tourists and passengers on a cruise. The basic idea is to create a sea lane independent from the usual land routes which are highly congested by the daily massive and repeated movements of residents, between the south-west and the north-west of Palermo

Surgical approach to the cavernous sinus for a trigeminal schwannoma resection: technical note and case report

We report a rare case of schwannoma of the lateral wall of the cavernous sinus, an exceedingly rare lesion affecting this anatomical district, and discuss salient aspects of the surgical approach to the cavernous sinus, which are traditionally considered technically challenging due to the high risk of postoperative morbidity and mortality related to the presence of the cranial nerves and internal carotid artery

Triple negative breast cancer: new perspectives for targeted therapies

Breast cancer is a heterogeneous disease, encompassing a large number of entities showing different morphological features and having clinical behaviors. It has became apparent that this diversity may be justified by distinct patterns of genetic, epigenetic, and transcriptomic aberrations. The identification of gene-expression microarray-based characteristics has led to the identification of at least five breast cancer subgroups: luminal A, luminal B, normal breast-like, human epidermal growth factor receptor 2, and basal-like. Triple-negative breast cancer is a complex disease diagnosed by immunohistochemistry, and it is characterized by malignant cells not expressing estrogen receptors or progesterone receptors at all, and human epidermal growth factor receptor 2. Along with this knowledge, recent data show that triple-negative breast cancer has specific molecular features that could be possible targets for new biological targeted drugs. The aim of this article is to explore the use of new drugs in this particular setting, which is still associated with poor prognosis and high risk of distant recurrence and death

Ancient Schwannoma of the Cauda Equina: our experience and review of the literature

Ancient schwannomas (AS) are exceedingly rare variant of common schwannomas (CS). Only two cases involving the cauda equina region have been previously reported in literature. AS are typically associated with a higher histological degree of degenerative changes (Antoni B areas). It is of peculiar importance, according to our opinion, to outline that, because of their extremely slow growth (which explains the increase of the degenerative changes in respect to the CS) and their typical soft consistency in respect to their standard counterparts, AS usually imply an even better prognosis

Gap acceptance analysis in an urban intersection through a video acquired by an UAV

Purpose of this paper is to apply a methodology previously developed to achieve an accurate measurements of the real traffic condition thought the use of a video acquired by an UAV (Unmanned Aerial Vehicle) and a probe vehicle equipped with a differential GPS. The used methodology is not invasive and thus, it doesn't influence the driver behavior. The used equipment must not be compared to the traditional techniques of traffic flow but it can be used for particular situations in which the installation of fixed detectors is not economic. In particular, we have analyzed the gap acceptance for an urban intersection between a main road with dual carriageway and two lanes in one direction, that connects the older town of Palermo with a main access roads (via E. Basile) and a secondary road used for local traffic and composed by a single carriageway with one lane for each direction (via U. Solarino)

Urban traffic analysis through an UAV

In order to realize a precise and accurate traffic study, a method to evaluate the real traffic flow conditions in urban areas based on videos acquired by an UAV, Unmanned Aerial Vehicle, is proposed. In this way it does not require additional equipment to earth and, not being invasive, does not influence the driver behavior. This paper presents the results obtained in terms of vehicular traffic flow along a way in the city of Palermo. The results have been compared to experiments using macroscopic simulation models and the eventually differences have been discussed

New mobility strategies for the development of tourism in Sicily

Tourism and Transport is a well established and inseparable pair. An areas can increase the tourism in potentially own economy. This requires suitable accommodation and adequate transportation system. A positive synergy effects are induced to increase of the site. Transport is an important growth area for tourism and as a result. A better functioning of transport facilitates access to sites, decreases the cost of transport and increases tourist flows. In Sicily there are a wealth of artistic, archaeological and natural sites, generating a tourist flows during the year. Despite this, the network of connections and services is precarious. Residents and visitors are inaccessible to certain geographical areas. Often airport nodes are isolated for tourist as residents and connections to main destinations are by road transport, because rail is not competitive. Congestion of the main arteries increase negative externalities related to road transport and for tourists increases the negative perception of the journey. In this paper we propose guidelines for sustainable tourism, by analyzing the supply of mobility. The case study examines the reality of the stretch of waterfront in Western Sicily (Palermo to Trapani), introducing a faster shipping service to facilitate accessibility to tourist sites along the coast, with a network of connections that includes airports nodes
