International Bordetella pertussis assay standardization and harmonization meeting report. Centers for Disease Control and Prevention, Atlanta, Georg…
2009
An international meeting on Bordetella pertussis assay standardization and harmonization was held at the Centers for Disease Control and Prevention (CDC), Atlanta, GA, 19-20 July 2007. The goal of the meeting was to harmonize the immunoassays used for pertussis diagnostics and vaccine evaluation, as agreed upon by academic and government researchers, regulatory authorities, vaccine manufacturers, and the World Health Organization (WHO). The primary objectives were (1) to provide epidemiologic, laboratory, and statistical background for support of global harmonization; (2) to overview the current status of global epidemiology, pathogenesis and immunology of pertussis; (3) to develop a consen…
Louseborne relapsing fever in young migrants, sicily, Italy, july-september 2015
2016
To the Editor: During the early 20th century, at the end of World War I, and during World War II, louseborne relapsing fever (LBRF) caused by Borrelia recurrentis was a major public health problem, especially in eastern Europe and northern Africa (1,2). Currently, poor living conditions, famine, war, and refugee camps are major risk factors for epidemics of LBRF in resource-poor countries, such as those in the Horn of Africa (3,4). Increased migration from resource-poor countries and war/violence create new routes for spread of vectorborne diseases. Recently, several cases of LBRF have been reported among asylum seekers from Eritrea in the Netherlands, Switzerland, and Germany (5–8). All of…
FISIOPATOLOGIA DELLA SINTESI DELLE LIPOPROTEINE INTESTINALI
2015
La sintesi di lipoproteine di origine intestinale è un processo sequenziale, necessario per l’assorbimento dei lipidi e delle vitamine liposolubili di origine alimentare. L’assemblaggio dei chilomicroni inizia nel reticolo endoplasmico con la formazione di particelle ricche di fosfolipidi che sono poi trasportate al Golgi per essere secrete. Diverse classi di trasportatori giocano un ruolo sia nell’assorbimento selettivo che nel trasporto di lipidi attraverso i villi intestinali. Una volta secrete nel circolo linfatico, le lipoproteine ricche di trigliceridi (LRT) sono sottoposte all’azione della Lipasi Lipoproteica (LPL), che catalizza l’idrolisi dei triacilgliceroli delle lipoproteine a d…
"Corporate governance": approcci manageriali ed etici a confronto
2009
La crisi di fiducia che colpì il sistema delle imprese statunitense nei primi anni '70 ha promosso l'elaborazione di due distinte concezioni della corporate governance. La prima ha come referente privilegiato azionisti ed investitori ed elegge il mercato (azionario) come lo strumento principale per il governo dell'impresa. L'obiettivo di tale concezione è quello di riportare il management aziendale sotto il controllo degli azionisti. La seconda cerca invece di identificare una prospettiva che tiene nella dovuta considerazione preferenze, bisogni e diritti di tutti gli stakeholders coinvolti nel processo produttivo. Riprendendo la distinzione proposta da Hirschman, possiamo dire che mentre l…
A stochastic dynamic model to evaluate the influence of economy and well-being on unemployment control
2018
[EN] This paper presents a stochastic dynamic mathematical model to study the evolution of the unemployment rate and other relevant related variables in a country. This model is composed by three basic interrelated subsystems: demographic, economic and wellbeing ones. A key aspect of this model is that it considers three UN well-being variables simultaneously: Human Development Index, Gender Empowerment Index and Gender Differentiation Index. These variables involve key concepts for human development, as Health, Education, Economy and Female Labor. With this model, the most outstanding variables found in the literature in relation with unemployment control can be used to design strategies a…
Self-Enforcing, Public-Order Institutions for Contract Enforcement: Litigation, Regulation, and Limited Government in Venice, 1050–1350
2011
The spectacular economic growth of Venice during the late medieval period (1050–1350) was based on the expansion of its trade along the Mediterranean and beyond. Crucial to this expansion was the mobilization of large amounts of capital into risky investments. However, this mobilization required the development of institutions that protected creditors and shareholders from expropriation by controlling merchants. This chapter finds that legal and administrative institutions conjointly provided investor protection and explores the interactions between these public-order institutions for contract enforcement and the emergence of a limited government, a coercion-constraining institution that mo…
The Uncertain Role of Banks’ Corporate Governance in Systemic Risk Regulation
2011
This paper examines how corporate governance reform of banks relates to systemic risk. Although there has been substantial emphasis on the importance of corporate governance of banks, it is not entirely clear how this enterprise relates to the goal of financial stability. The first part of the paper differentiates between kinds of risk that arise from the structure of the firm, such as shareholder ownership, limited liability and the separation between control and ownership, and kinds of risk that arise from interactions at the systemic level. It highlights why the risk-taking of banks presents, in many respects, a special case not only because of the structure of their business but also becau…
The Mach cone signal and energy deposition scenarios in linearized hydrodynamics
2010
Particle correlation measurements associated with a hard or semi-hard trigger in heavy-ion collisions may reflect Mach cone shockwaves excited in the bulk medium by partonic energy loss. This is of great interest because, when compared with theory, such measurements can provide information on the transport properties of the medium. Specifically, the formation of Mach cone shockwaves is sensitive to the viscosity and speed of sound, as well as the detailed nature of the jet medium interaction. However, modeling the physics of shockwave excitation to obtain a meaningful comparison with the measured correlations is very challenging since the correlations arise from an interplay of perturbative…
MS-CASPT2 analysis of the UV thermochromism of octamethyltrisilane
2006
We interpret the reversal of the direction of the thermochromic shift of the first absorption band of peralkylated oligosilanes as the silicon chain is extended, based on multistate complete active space second-order perturbation theory (MS-CASPT2) calculations for octamethyltrisilane, Si3Me8. The observed shift is attributed to the effect of b1 distortions from ground state equilibrium geometry on vertical excited state energies and intensities. A generally contracted basis set of atomic natural orbitals (ANOs) at a ground state geometry optimized in the second-order Moller–Plesset perturbation theory (MP2) approximation with Dunning's correlation consistent triple-zeta basis set (cc-pVTZ)…
Photoelectron lifetime determination of Ag(1 1 1) films at the Fermi surface
2001
The electronic properties of 10 monolayers Ag(111) films deposited onto Si(111)-7 x 7 substrates at room temperature have been studied by scanning the photoelectron intensity at the Fermi level in different symmetry directions. The main features observed in these profiles correspond to Lorentzian-like peaks produced by the pass of the sp band through the Fermi level. A simple model has been developed, which connects the photoemission peak linewidth with the lifetime of photoelectrons excited from the Fermi level. The obtained inverse photoelectron lifetime values have been found to be in excellent agreement with the typical values of the Ag single crystals. These results support the fact th…
