Using data on 75 big Italian municipalities between 2010 and 2015, this paper looks at the extent to which citizens’ evaluations of mayors are responsive to changes in local performance indicators. While local economic and crime measures are found not be associated with mayoral approval ratings, there is a correlation between mayors’ popularity and indicators for local public transportation and air quality. Mayors of municipalities where more individuals use public transport and where there is less polluted air enjoy higher approval ratings. Additional analysis shows that this result is driven by very big municipalities (with a population over 500,000) that are more likely to be exposed to high levels of traffic congestion and pollution.  相似文献

Even after the conflicts of the early 1990s that brought them to their de facto independence, both Abkhazia and Transnistria remained strongly multi-ethnic. In both territories, no single ethnic group is an absolute majority and Russian is the language that is mostly spoken on the streets of Sukhumi and Tiraspol. Legislators of both entities felt the need to deal with multi-ethnicity and multilingualism, including in their constitutions, in laws related to education, or more directly with specific language laws (1992 law “On languages” in Transnistria; 2007 law “On the state language in Abkhazia”). The protection of linguistic rights that is formally part of the legislation of both territories finds limitations in practice. The language of education has proved to be particularly contentious, in particular for Moldovan/Romanian language schools in Transnistria and Georgian language schools in Abkhazia. Why are language laws in Abkhazia and Transnistria so different, in spite of the fact that they are both post-Soviet, multi-ethnic territories that became de facto independent in the early 1990s? The different approaches found in Abkhazia and Transnistria represent remarkable examples of language legislation as a tool for nation-building in ethnically heterogeneous territories.  相似文献

Beta-carboline alkaloids harmine, harmaline, and tetrahydroharmine can stimulate the central nervous system by inhibiting the metabolism of amine neurotransmitters, or by direct interaction with specific receptors; they are found in numerous plants, including Peganum harmala, Passiflora incarnata and Banisteriopsis caapi, and in the entheogen preparation Ayahuasca, which is traditionally brewed using B. caapi to enhance the activity of amine hallucinogenic drugs. The ingestion of plant preparations containing beta-carboline alkaloids may result in toxic effects, namely visual and auditory hallucinations, locomotor ataxia, nausea, vomiting, confusion and agitation. We report a case of intoxication following intentional ingestion of P. harmala seed infusion; P. harmala seeds were bought over the Internet. The harmala alkaloids were identified by gas chromatography-mass spectrometry in the seed extract and the patient's urine. This is, to our knowledge, the first case of P. harmala intoxication corroborated by toxicological findings.  相似文献

Post-mortem diagnosis of chronic alcohol abuse is a challenge for forensic experts due to the lack of pathognomonic morphological findings and often also inadequate background information. Objective methods demonstrating chronic excessive alcohol consumption would therefore be a useful tool for forensic pathologists. In clinical practice, several markers of chronic alcohol abuse have recently been introduced, among which carbohydrate-deficient transferrin (CDT) is the most accepted, but the use of these markers in autopsy has not yet been established. We examined post-mortem stability and possible post-mortem redistribution of CDT and compared two analytical methods, capillary zone electrophoresis and high-performance liquid chromatography. According to our results, CDT remains stable for an appreciable time after death. The results further indicate that CDT is not subject to major post-mortem redistribution.  相似文献

Deaths due to meningiomas are routinely diagnosed in clinical practice because this neoplasm tends to present with the typical progression of neurological deficits. On the other hand, sudden unexpected deaths due to meningiomas are rarely described in the literature. The study presents six fatal cases of previously undiagnosed intracranial meningiomas from the Cook County Medical Examiner's Office from 1998 to 2014. The most common explanation of the mechanism of sudden death due to intracranial neoplasms is a rapid increase in intracranial pressure produced by the mass effect of the neoplasm. Other mechanisms of death include acute intracranial and intratumoral hemorrhage, and benign neoplasms that grow in the vicinity of vital centers altering neural discharge in autonomic pathways leading to cardiac suppression or lethal arrhythmia. Forensic pathologists must keep in mind that sudden unexpected death caused by intracranial meningiomas, although extremely rare, may be encountered in the forensic setting.  相似文献
