Una nuova acquisizione iconografica per la ricostruzione della tribuna di Antonello Gagini nella Cattedrale di Palermo

2022

La recente digitalizzazione di un dipinto di anonimo siciliano nelle collezioni del Museo de Historia di Madrid e il suo inserimento nei database del patrimonio culturale spagnolo ed europeo ha consentito di riportare all’attenzione della comunità scientifica un’importante raffigurazione pittorica della tribuna di Antonello Gagini nella Cattedrale di Palermo. Dopo avere ripercorso le principali fonti documentarie ed iconografiche relative alla tribuna, viene qui presentata l’opera oggi a Madrid, che fornisce un prezioso riscontro alle fonti fin qui note.

Detectability of cannabinoids in the serum samples of cannabis users: Indicators of recent cannabis use? A follow‐up study

2021

Forensic toxicologists are frequently required to predict the time of last cannabis consumption. Several studies suggested the utility of minor cannabinoids as indicators of recent cannabis use. Because several factors influence blood cannabinoid concentrations, the interpretation of serum cannabinoid concentrations remains challenging. To assess the informative value of serum cannabinoid levels in cannabis users (in total N = 117 patients, including 56 patients who stated an exact time of last cannabis use within 24 h before blood sampling), the detectability of cannabinoids, namely delta-9-tetrahydrocannabinol (delta-9-THC), 11-hydroxy-delta-9-THC, 11-nor-9-carboxy-delta-9-THC, cannabichr…

Copper, iron, and zinc contents in human milk during the first three months of lactation: A longitudinal study

2000

The aim of the study has been to analyze the evolution of copper, iron, and zinc contents in human milk, from colostrum to the third postpartum month, following a longitudinal design, under specific conditions of sample collection and to apply an analytical procedure previously optimized to reduce any variation outside physiological lactation. The copper, iron, and zinc concentrations in 144 milk samples from 39 healthy puerpera women, were analyzed in five stages by flame atomic absorption spectrometry, following a standardized protocol. Copper presented a gradual decrease from 0.38 mg/L to 0.19 mg/L by the 90th day; the particular analysis from colostrum to transitional milk manifested th…

Occupational health disparities among U.S. long-haul truck drivers: the influence of work organization and sleep on cardiovascular and metabolic dise…

2018

Objective The organization of work has undergone vast transformations over the past four decades in the United States and has had profound impacts on worker health and wellbeing. The profession of commercial truck driving is one of the best examples. Particularly for long-haul truck drivers, changes in work organization have led to disproportionately poor physiological, psychological, and sleep health outcomes. Methods The present study examined disparities in cardiometabolic disease risk among long-haul truck drivers and the general population, and the influence of work organization and sleep in generating these outcomes. Researchers collected survey data from 260 drivers, and blood assay …

De la encuesta a la base de datos: experiencia de trabajo de campo del estudio «Inmigración, trabajo y salud» (Proyecto ITSAL)

2011

Objective: Despite the need for information in the area of migration and health, the available data are sparse. We describe the field work in a cross-sectional study on the health of immigrant workers in Spain. Method: A convenience sample of workers from Colombia, Ecuador, Morocco and Rumania in four cities was targeted, using a block-walking approach. The outcome rates of the American Association of Public Opinion Research were estimated. Results: Of 6,504 persons approached, 71.4% were eligible contacts. Of these contacts, only 57.8% completed interviews. Response and cooperation rates were above 50%. Conclusions: Block-walking enabled surveyors to access difficult-to-reach groups. The u…

A critical perspective on Integrated Project Delivery (IPD) applied in a Norwegian public hospital project

2020

Does the IPD concept deliver as required and expected, and if not, how can that be explained? This paper is a critical realist inspired methodology based on a combination of the inductive and deductive approaches used in case study research. IPD is based on relational contracting between multiple parties, in this case between the Owner, Contractor, MEP subcontractors and a group of Consulting engineers who share control of the project. At the core of the concept is shared risk and opportunities among the parties in the IPD contract. Our theoretical perspectives are based mainly on the Principal-Agent theory (PA), Transaction Cost theory (TC), and its related incentives. This paper reports o…

A transaction cost analysis of staffing decisions in international operations

2005

Abstract This paper analyzes staffing decisions in foreign subsidiaries from the perspective of transaction cost theory. We focus on the ex post transaction costs of the employment relation. Specifically, we look at the monitoring, bonding, maladaptation, and bargaining costs of conducting activities in specific subsidiaries in a foreign country. We hypothesize that the transaction costs of using expatriates are lower than those generated by local employees, especially in the higher managerial echelons of foreign subsidiaries, but also that costs can be reduced as individuals become more experienced. We also conjecture that ex post transaction costs are influenced by cultural differences be…

Toward an urban transport sustainability index: an European comparison

2011

Introduction The aim of paper is to cluster policies of sustainable mobility in order to define an essential set of specific Transport Performance Indicators (TPI). TPIs are standardized measures suitable for analysis in order to appraise the feasibility of a transport policy or an infrastructural project. Data collection of TPIs is a crucial phase, but data detection and monitoring are not standardized at the city level. Thus, there is no a standard for data collection and storing, this aspect makes much difficult to compare different city contexts. This issue is critical and bounds the analysis of built scenarios. A standardized set of transport performance indicators becomes, hence, esse…
