ABSTRACT The financial crisis beginning in 2007 drastically affected the financial resources of different governmental organizations, causing critical imbalances between resources and expenditure needs. This study aims to analyze whether the municipal tax collection effort in Spain could be an indicator of the financial condition of these institutions. As a preliminary step, a new methodology is used to assess their financial condition. We test tax collection effort as an indicator on a sample of more than 5,000 Spanish municipalities with fewer than 75,000 inhabitants. Results confirm that the budgetary solvency dimension is associated with the tax collection effort for all municipalities studied. Furthermore, in municipalities with populations of fewer than 5,000 inhabitants, the level of the tax collection effort is indicative of most of the financial condition dimensions. 相似文献

In this essay I defend the idea that the mexican legal order has been partially constitutionalized since the amendment to the first article of the Constitution in june 2011. I argue that some conditions of a constitutionalized legal system can be found in this rule. An analysis of those conditions is carried out through the work and in the end I discuss the matter of whether this constitutional change amounts to a new legal paradigm. 相似文献

This study analyses the factors that influence citizens' intention to use e-government activities offered by municipalities in Spain. For this purpose, we developed a straightforward user behaviour model that considers the components of the TAM and DOI models simultaneously, harnessing their synergies and factoring in the role of citizens' trust. We also examined the moderating role that population size can play in the model's behaviour. Among the results we obtained, it is important to note that user trust not only improved the model's fit, but also showed a significant effect on intention of use for all the population sizes that we analysed. The other significant relationship for all the samples linked ease of use to perceived usefulness. For the other relationships between variables, we observed the moderating role of size for the populations we considered. 相似文献

A fast and simple LC-MS/MS method was developed for screening mephedrone, butylone, methylenedioxypyrovalerone (MDPV), flephedrone, methylone and methedrone in bulk powder samples. Samples were separated on a reverse phase column using gradient elution with mixtures of water, acetonitrile and formic acid. After optimization a limit of detection of about 2ngmL(-1) was achieved using multiple reaction monitoring (MRM) mode. Total run time was less than 8min. Typical fragmentation characteristics of the studied compounds are discussed. The method was successfully applied to several unknown bulk powder samples seized by the Hungarian Customs and Finance Guard. One of the samples contained the new designer drug 4'-methylethcathinone (4-MEC), which was identified and characterized by LC-MS/MS, NMR, FT-IR and LC-TOF-MS techniques. The method is also deemed to be applicable for the screening of simple dosage forms such as tablets and capsules. 相似文献

This article presents the first record of Hermetia illucens larvae on a human corpse in Spain (the second case report in Europe). Prepupae of H. illucens, and other insects, were recovered from the dead body of a 72-year-old man in an advanced stage of decomposition. The body was located in Reus (NE Spain), in October 1998. This article provides additional biological data on experimental studies and an update on the geographic distribution of this species in the Iberian Peninsula. 相似文献

An effective way to reveal the history of drug abuse is to determine the parental drug and its metabolites in hair. Here, a quantitative HPLC-Chip-MS/MS method was developed for simultaneous measurement of ketamine and its metabolite norketamine in human hair. Ketamine and norketamine were extracted from hair by acid hydrolysis, and then enriched by organic solvent extraction. The chromatographic separation was achieved in 15 min, with the drug identification and quantification by a tandem mass spectrometer. The linear regression analysis was calibrated by deuterated internal standards with a R(2) of over 0.996. The limit of detection (LOD) and the limit of quantification (LOQ) for ketamine and norketamine were 0.5 and 1 pg/mg of hair, respectively. The standard curves were linear from the value of LOQ up to 100 pg/mg of hair. The validation parameters including selectivity, accuracy, precision, stability and matrix effect were also determined. In conclusion, this method was able to reveal the present of ketamine and norketamine with less hair from the drug abusers, and which had the sensitivity of ~1000-fold higher than the conventional method. In addition, the amount of ketamine and norketamine being detected in different hair segments would be useful in revealing the historical record of ketamine uptake in the drug abusers. 相似文献

The objective of this study was to investigate psychological or physical violence associated with the use of alcohol, in residences
of individuals in Brazil and, also describe the social characteristics of aggressors and victims. Therefore, this study expects
to contribute to studies in Brazil that seek to clarify the relations between alcohol and violence in residences. A total
of 454 respondents, 12–65 years old, were assessed, they were sorted by the Kish method, and the residences randomly. The
SAMHSA questionnaire was utilized after translated and adapted to Brazilian conditions. 26% of the individuals reported psychological
violence, and 16% reported physical violence. The study’s main results set the differences in the reports for physical violence
(OR 7, 95% CI: 4–13) and psychological violence (OR 5, 95% CI: 3–8) in residences where someone arrived or became intoxicated
with alcohol (P < 0.05). 50% of the aggressors were under the effects of alcohol, and 77% of the victims were relatives of their aggressors.
Acts of violence are not necessarily associated with alcohol consumption. Men and women reported acts of domestic violence;
psychological violence was the most prevalent form. Men are currently the primary aggressors, while women are primarily the
victims 相似文献

Debates on how the law affects citizens' behaviour have traditionally focused on two mechanisms: deterrence and perceptions of legitimacy. In recent years, some scholars have suggested that the law may also affect compliance through expressive mechanisms that reveal information about the world (for example, by eliciting the risks associated with a particular behaviour). Dharmapala and McAdams have called this the informative effect of law. However, to date very little empirical evidence of the existence of such an effect has emerged. In this article, we present the results of an experiment that tests for three different hypotheses as to how this effect may be produced. Our findings show that legislators' sincerity or their access to expert knowledge is not sufficient to produce information effects. Instead, we suggest an ‘asymmetry’ hypothesis: the fact that a law is passed or rejected has an asymmetrical information effect on subjects' risk perceptions. 相似文献

Studies of cross-border regions in the European Union have struggled conceptually with an apparent ambiguity of Euregionalism: namely that cross-border regions seem to be the manifestations of reterritorialising state governance on the one hand, but have clearly failed to substantially challenge the Westphalian state territorial system on the other. The aim of the present paper is to develop a conceptual framework that helps us understand this paradoxical nature of cross-border regions. To this end, we draw on the systems theory of Niklas Luhmann and the semiotics of Charles Sanders Peirce, and propose to regard Euregionalism (and regionalisms more generally) as a self-organising system. Self-organisation entails the process in which self-referential communication, rather than a set of actors, employs spatial concepts, such as the region, to enable system-specific entanglements with physical space, either short-lived or enduring, and possibly – but not necessarily – involving governance. 相似文献
