Threshold effects and the expected benefits of attracting middle‐income households to the central city

Abstract

This article looks at the two primary expected benefits of efforts to bring back, or retain, middle‐income households in the central city: (1) improved fiscal conditions caused by increasing the tax base and (2) decreased socioeconomic isolation of central‐city low‐income households. We examine the causal linkages reputed to produce these two benefits in light of the relatively limited relevant theoretical and empirical research.

Although stressing that this work is only tentative and intended to be provocative, we cautiously conclude that thresholds matter. That is, it is likely that the number of middle‐income households in a given area must exceed a certain threshold for significant benefits to accrue. The geographic scale of this area, the threshold that applies, and the time needed for benefits to appear depend on the particular causal linkage at issue. In the last section, we derive implications for research and policy evaluation.     

Suicide by Self‐Administration of a Drug Mixture (Propofol,Midazolam, and Zolpidem) in an Anesthesiologist: The First Case Report in Italy

The authors report an unusual case of suicide of an anesthesiologist, in which the suicide manner and means depend upon the victim's occupation. This is the first case report published in Italy of a death involving propofol and other drugs. The anesthesiologist was found dead with an empty drip still inserted in the hand and another one near his body. Forensic and toxicological findings suggested that the cause of death was a respiratory depression due to a self‐administration of a rapidly infused lethal drug mixture. Analytical drug quantification was performed by gas chromatography‐mass spectrometry. Blood analysis revealed: zolpidem (0.86 μg/mL), propofol (0.30 μg/mL), midazolam (0.08 μg/mL), thiopental (0.03 μg/mL), and amitriptyline (0.07 μg/mL). Adipose tissue and hair analysis suggested a previous and repeated use of these drugs verifying the fact that in Italy recreational abuse of anesthetic and sedative agents in health care practitioners is becoming an increasing problem.     

Barbárie: literatura e filosofia moral

The view of the barbarity is a theme that has been inexhaustible due to the constant human ability of reinventing the horror’s dimensions. However, if analyzed through the political philosophy, this is a theme that requires continuous rereadings in order to prevent the risk of reactualization of the horror in the contemporary world’s roll of concerns. The horror’s reactualization in this context would be assisted by the weakness that is currently happening at the democratic institutions as a result of virulent denouncing criticisms that expose its infirmity, often deservedly. We believe that the barbarity is unembraceable and unapproachable in its integrality if seen through one single angle. Therefore, our purpose in this text is supporting the continuous process of reflecting about this theme through the possible conjunctive approximation of literature (Jünger and the survival’s literature) and political philosophy (Schmitt and his critics).     

Italy's Growing Burden of Choice in Security Policy

NATO, the EU, and the UN have been the cornerstones of Italy's foreign policy since WWII: although they continue to provide a point of reference, these institutions are undergoing major changes that reflect – and partly create – a very unpredictable international environment. The evolving security agenda, choices made by key allies (especially the United States), and domestic political forces are putting Italian decision-makers under pressure. There is a serious problem of resource constraints while the country is still unwilling to make clear-cut choices based on unavoidable tradeoffs. The past few years have witnessed a mix of continuity and change due to the political orientations of successive governments under these challenging circumstances.     

Notes and topics

The European Union's difficulty in functioning is to a large degree a result of its decision-making mechanisms, which expose any measure to a veto by a scant minority or even a single state. A flexible model of Europe, one of differentiated integration, attempts to overcome this deadlock. The flexible model is based on the simple and reasonable idea that a member state which dissents is not obliged to associate itself with a certain initiative, but cannot stop the others from carrying it out. Under certain “virtuous” conditions, flexibility would not involve the risk of breaking up the Union. On the contrary, it would offer dynamic instrument for reconciling the requirements of unity and diversity and promoting the process of European integration.
