Glucokinase Regulatory Protein Gene Polymorphism Affects Liver Fibrosis in Non-Alcoholic Fatty Liver Disease
2014
BACKGROUND AND AIMS: Variant in glucokinase regulatory protein (GCKR), associated with lipid and glucose traits, has been suggested to affect fatty liver infiltration. We aimed to assess whether GCKR rs780094 C-->T SNP influences the expression of steatosis, lobular inflammation and fibrosis in NAFLD patients, after correction for PNPLA3 genotype. METHODS: In 366 consecutive NAFLD patients (197 from Sicily, and 169 from center/northern Italy), we assessed anthropometric, biochemical and metabolic features; liver biopsy was scored according to Kleiner. PNPLA3 rs738409 C>G and GCKR rs780094 C>T single nucleotide polymorphisms were also assessed. RESULTS: At multivariate logistic regression an…
To Control or Not to Control
1998
To have control over an event means exercising authority and influence over it by directing and regulating it oneself. Obviously, events differ in their amenability to control. We cannot change the order of days in the week; our influence on our own health is greater but still limited. We may have almost total control over the amount of sugar and milk in our cup of coffee, but only if we prepare our breakfast ourselves. Regardless of the objective nature of the situation, however, people vary in their assessments of perceived control over particular events and their lives in general. Some feel they can do almost anything they set their minds to; others feel that events result mostly from th…
How to Avoid Compensating CEO for Luck: The Case of Macroeconomic Fluctuations
2010
Incentive effects of performance-based compensation schemes for management may be weakened or biased by macroeconomic influences on remuneration. These influences can be seen as reflecting luck from the CEO’s perspective. In this chapter we present a model for how to avoid compensating CEO for luck by filtering out the macroeconomic influences. In the empirical section we analyze the impact of macroeconomic, industry and firm-specific factors on the compensations (salary, bonus, options, and pensions) of CEOs in 127 Swedish corporations during the period 2001-2007. We find macroeconomic influences on Swedish CEOs’ compensation to be substantial. Distinguishing between favorable and unfavora…
Quarry limestone dust as fine aggregate for concrete
2018
In quarrying activities, rock is extracted and transformed into aggregate of various sizes for civil engineering applications. In this process waste fine aggregates (dust waste) are generated. The disposal of this type of waste is a further cost in the extraction process, but also a possible cause of environmental pollution (e.g. leaching into water reserves, atmospheric pollution as a result of small particles causing respiratory diseases or deposited on plants disrupting photosynthesis, affecting aquatic habitats, etc.). A strategy for the effective recycling of quarry dust does not only reduce waste generation and disposal, but also addresses protection of the environment. The Italian qu…
Managing palaeontological heritage: a brief overview of policy and practice in England
2019
Fossil collecting for scientific and educational reasons, as well as to support natural curiosity, has taken place in England since at least the late eighteenth century. It was not, however, until the late nineteenth, and particularly the mid-twentieth century, that site-based conservation of palaeontological heritage, and the management of collecting, was established. This paper provides a brief overview of the development of the policy and practice of palaeontological heritage management in England. It includes an outline of the establishment of national legislation, and a summary of the practical approaches to managing palaeontological sites and the collection of fossils that have been a…
Marble quarrying: an energy and waste intensive activity in the production of building materials
2008
Marble represents an important component of Italian buildings, where it is often utilized as a covering for bottom surfaces, despite its relatively high price. Moreover, it characterizes several public buildings, for which it is by far the most important decorative material, also because of its structural features and its long durability. Unfortunately, marble quarrying is an energy intensive activity that requires relevant amounts of electric and thermal energy sources; in addition, the extraction of the marble blocks from the mountain sides does involve a noticeable quantity of explosives, particularly in sites where traditional working methods are utilized. Another important feature of t…
Energy and environmental analysis of marble productive sites: «by phases» and «by single process» combined approach

Mines and quarries production: A driver analysis of withdrawals in Italy
2020
Abstract The growing demand for non-energy mineral resources has determined relevant withdrawals as well as import-export flows. This paper aims to disentangle the drivers of raw non-energy mineral resources extraction in Italy. Using a new dataset of raw resources extracted from mines and quarries in the 21 Italian regions (19 regions and 2 autonomous provinces of Trento and Bolzano) for the period 2013–2016, our empirical analysis confirms the relevance of mining and quarrying producer price index as well as the manufacturing and construction sectors as main drivers. In line with the Hotelling (1931)'s theory, a positive relationship between m&q mineral resources extraction intensity and …
Serendipity and innovation: history and evolution of transthoracic echocardiography
2017
The history of echocardiography is sprinkled with many interesting episodes and anecdotes showing that devoting your life to the pursuit of one goal is praiseworthy, and that at the same time, a little luck goes a long way. Transthoracic echocardiography (TTE) has led to dramatic improvements in cardiovascular medicine, and is now the most widely used diagnostic cardiac test after electrocardiography (ECG). The present review pays tribute to the pioneering efforts of those who believed in this innovative technology despite mounted skepticism and briefly describes the evolution of TTE from its early days to the most recent developments.
Toward a holistic environmental impact assessment of marble quarrying and processing: proposal of a novel easy-to-use IPAT-based method.
2016
Marble is a natural dimension stone that is widely used in building due to its resistance and esthetic qualities. Unfortunately, some concerns have arisen regarding its production process because quarrying and processing activities demand significant amounts of energy and greatly affect the environment. Further, performing an environmental analysis of a production process such as that of marble requires the consideration of many environmental aspects (e.g., noise, vibrations, dust and waste production, energy consumption). Unfortunately, the current impact accounting tools do not seem to be capable of considering all of the major aspects of the (marble) production process that may affect th…
