This paper presents and discusses three cases of cadavers found, unburied, in the province of Venice, Northern Italy. In each case, all insect species playing some role in carrion decay processes, both sarcophagous and their predators, found on or in the bodies, were collected and determined. In one case, many larvae of the black soldier fly, Hermetia illucens L. (Diptera: Stratiomyidae) were found and are reported, for the first time in Italy, as necrophagous. Experimental breeding of some fly species was also carried out in controlled temperature and humidity conditions. In particular, it was of interest to know how the Neotropical black soldier fly modified its life-cycle to adapt to a temperate climate. It was thus possible to establish the rate of larval growth and timing of pupation, emergence, oviposition and hatching in various external conditions. The postmortem interval (PMI) established by identifying the life-cycle stages of dipterofauna were later confirmed in all cases through police investigations and the results of forensic analyses. 相似文献

This paper analyses exchange rate series for Poland and Brazil. The Polish series, related to the period soon after the first liberalizing measures, presents a high volatility which is not accounted for by some selected ‘fundamentals’. The Brazilian series, though also keeping evidence of excessive volatility, is cointegrated with fundamentals similar to those of the Polish case. This raises the issue of a learning process taking place during persistent inflations. Unsuccessful one-shot stabilization plans can reinforce this process, leaving a lasting imprint in the excessive volatility pattern. The message seems clear, though maybe not easy to implement: agents take some time to learn to live in non-stable environments; to avoid this by one-shot measures — if unsuccessful — can have a very high cost and pre-empt future corrections. 相似文献

After the fall of the Qadhafi regime Libya has become a theatre of conflict and violence. In the midst of the vacuum left by the sudden collapse of the old regime, various groups have come to contest their role in a new Libya. Illicit trafficking and the exploitation of oil resources have contributed to this struggle by empowering certain actors over others and by exhausting the capacity of the state. This article investigates the derailing of the Libyan transition and the opening of a new phase of conflict from a political economy perspective. It engages with key arguments developed in the literature on the economic causes of war and shows that the conflict in Libya challenges some of their conclusions. The establishment of areas of de facto sovereignty—warlordism—suggests two key factors explaining the discrepancy between theoretical arguments and empirical evidence: the problematic and contested definition of state and non-state actors in Libya; and an emerging political economy which is best described as an overproduction of governance rather than a lack of it. 相似文献

During the international financial crisis, Portugal found itself in a very difficult and vulnerable socioeconomic situation that has led to an increase in social inequalities. This article seeks to understand two things: firstly, how much the impacts of the crisis contributed to a general perception that people's social position has gone backwards, compared to their pre-crisis situations; secondly, whether it is possible to link this generalized perception that living conditions have gone downhill to an increase in and diversification of collective action practices. The authors analyse data from a 2014 survey of 1,500 residents of the Lisbon Metropolitan Area, which they use to measure how far the level of collective action practices has increased and varied in accordance with a set of social inequality indicators, such as resource and educational inequalities. 相似文献

In 2009, extensive performance management measures were introduced in Italian ministries, following a significant legislative initiative. The objectives that were initially set, however, have not yet been reached. In the paper, the authors discuss this issue, starting with the consideration of the main limits on the introduction of performance measurement systems in public organizations. The discussion leads to the conclusion that the shortcomings of performance management depend not only on the persistence of an administrative paradigm, but also on the underestimated impact of control over organizational behavior; where the latter is linked not to mechanical logic processes, but to more sophisticated forms of reactivity or even counter-intuitive sense-making processes. 相似文献

The decision to intervene in ongoing conflicts is one of the most difficult foreign policy choices states often face. Yet, studies of third parties' joining behavior have been rare and limited in several respects. First, they have explored only a subset of all interventions—military interventions. Second, they have concentrated on security-based determinants of intervention—power and alliance considerations—while underplaying other possible motivations behind the decision to intervene. Third, they have explored intervention and alignment choices as separate issues. This paper proposes a model of joining behavior that includes both security considerations and homophilous network ties as determinants of third parties' intervention and alignment choices. The model is tested on military and nonmilitary interventions data from Corbetta and Dixon (2005) for the 1946–2001 period. The results from a boolean logit estimation indicate that (1) the intervention decision is the result of both security-driven, pragmatic considerations and homophily between joiners and disputants; and (2) opposition to a party in a conflict is as important as a third party's social proximity to the side being supported. 相似文献
