The 2016 constitutional referendum could have marked a new phase in Italian politics, producing a clear shift towards a majoritarian (and de facto presidential) democracy. But a substantial majority of voters rejected the reforms promoted by Matteo Renzi, leading to his resignation as Prime Minister. Once again, an attempt to redesign the Italian institutional framework failed due to party conflicts. This time, the referendum turned into a vote on Renzi himself. This article examines the background to the institutional reforms and the changing dynamics of the referendum campaign. Discussing the final outcome, it argues that this could produce a sort of U-turn in the long Italian transition.  相似文献

Abstract: In a public hospital, eight cases of fatal poisoning by nitrous oxide (N2O) occurred under oxygen administration, due to an erroneous swapping of the lines in the gas system. The aim of the study was to clarify the factors involved in asphyxia by characterizing gases from different lines and measuring N2O concentrations in postmortem biological samples from bodies exhumed. Analyses carried out on the gas system confirmed the erroneous substitution of O2 line with N2O and air line with O2. Consequently, high N2O amounts were revealed in several tissues and gaseous biological samples. All specimens were analyzed by headspace gas chromatography technique. A rigorous quantitative analysis was possible only in blood (11.29–2152.04 mg/L) and urine (95.11 mg/L) and in air samples from stomach and trachea (from 5.28 to 83.63 g/m3). This study demonstrates that N2O can be detected in biological samples even 1 month after death.  相似文献

Accurate age estimation has always been a problem for forensic scientists, and apposition of secondary dentine is often used as an indicator of age. Since 2004, in order to examine patterns of secondary dentine apposition, Cameriere et al. have been extensively studying the pulp/tooth area ratio of the canines by panoramic and peri-apical X-ray images. The main aim of this paper is to examine the relationship between age and age-related changes in the pulp/tooth area ratio in monoradicular teeth, with the exception of canines, by orthopantomography. A total of 606 orthopantomograms of Spanish white Caucasian patients (289 women and 317 men), aged between 18 and 75 years and coming from Bilbao and Granada (Spain), was analysed. Regression analysis of age of monoradicular teeth indicated that the lower premolars were the most closely correlated with age. An ANCOVA did not show significant differences between men and women. Multiple regression analysis, with age as dependent variable and pulp/tooth area ratio as predictor, yielded several formulae. R(2) ranged from 0.69 to 0.75 for a single lower premolar tooth and from 0.79 to 0.86 for multiple lower premolar teeth. Depending on the available number of premolar teeth, the mean of the absolute values of residual standard error, at 95% confidence interval, ranged between 4.34 and 6.02 years, showing that the pulp/tooth area ratio is a useful variable for assessing age with reasonable accuracy.  相似文献

The revision of the Italian tax laws on trusts reduces the riskof different interpretations on the taxation of trusts and whichshould encourage a better understanding and use of trusts byresidents in Italy. The authors examine the new law and discussthe interpretation of some of the more difficult provisions.  相似文献

Barack Obama's first year should appear disappointing only to persons blind to the constraints imposed by the Bush legacy, the still reeling world economy, an intimidating agenda of domestic problems, a polarised domestic politics, and at least temporarily intractable opponents of the President's undoubted ambitions to tame the Middle East and promote cooperation among the leading states without jettisoning a commitment to liberal values. By ordering an end to torture and moving to close Guantanamo, he has signalled the restoration of moral restraint on the exercise of American power and implicitly expressed belief in the efficacy of soft power assets. Additionally, he has attempted to create political space for change by pushing the conventional limits of American presidential discourse. A decent start, but the hard part lies ahead.  相似文献

Abstract

In the wake of highly volatile world prices of staple commodities, we examine the impacts of increases in maize prices on various categories of households in Malawi. Using household-level data, changes in household income are calculated taking into account the net maize production status of the household and food price elasticities estimated from a censored demand system. While maize price increases have unequivocal deleterious effects on the incomes of urban households, rural households experience differential impacts. Net producing households in rural areas benefit from price increases with households above the poverty line obtaining proportionally higher incomes.  相似文献

We set up an evolutionary game-theoretic model aimed at addressing the issue of local public good provision via direct commitment of voluntary forces (private donors and nonprofit providers) only. Two classes of agents are assumed to strategically interact within a ‘double critical mass’ model and we investigate the critical factors affecting the dynamic outcomes of such interaction. Further, we explore the conditions under which (what we term) ‘evolutionary crowding-out/in’ occurs, depending on agents’ degree of opportunism, social comparison and positive selective incentives (such as subsidies given by the government to ‘virtuous’ citizens or nonprofits only).  相似文献

This paper develops a framework for the analysis of gatekeeping in tax enforcement, whereby independent auditors are assigned the duty of attesting taxpayers’ returns. The equilibrium of the market for gatekeepers’ services is characterized, as well as taxpayers’ and auditors’ optimal behavior. The paper identifies the conditions under which the introduction of a mandatory attestation system is likely to be desirable.The results of the paper suggest that: (1) collusion may disrupt the gatekeeping system if the compounded liability of the auditor and the taxpayer is not sufficiently high; (2) a more extended delegation of the enforcement power to private auditors is generally desirable; (3) the cartelization of the gatekeepers’ market has definitely detrimental effects; and (4) when the probability that erroneous attestations are detected and sanctioned depends on the effort exerted by a public enforcer, multiple equilibria may arise, due to the substitutability of public and private monitoring.  相似文献
