Using the Princeton nuptiality index Im, we analyzed historical developments in the proportion of married women of reproductive age in Spain. We show the internal diversity in nuptiality patterns and offer an explanatory statistical model based on panel data analysis to identify the main variables influencing these changes over more than a century (1887–1991). We found that Spain has been the developed country with the greatest contrasts in its provincial nuptiality patterns (measured by Im), although this diversity has lessened over the course of time. We also found that some socioeconomic variables (the gross domestic product per capita and the percentage of population living in cities) do not have a linear relationship with female nuptiality but rather have a U shape or an inverted U shape. This may partly account for some of the controversy that has raged on this topic over the past few decades on an international level. 相似文献

This study approaches the Chinese reform process from a political-economic point of view, focusing primarily on institutional changes. Besides revealing the main factors behind the different phases of the reforms, it argues that in the framework of the current authoritarian regime, vested interests work against the continuation of the reforms, making it impossible to fully establish the institutional framework of a market economy. Current rents and privileges also deter the elite from implementing serious political reforms, leading to a trap that prevents the completion of the transition process. 相似文献

This article sheds new light on how the Venezuelan Opposition was created and, more widely, on contemporary Venezuelan politics. By focusing on the Opposition's articulation of democracy, the article examines how this movement became possible and how it succeeded in maintaining support. Opinion articles covering the period October 2001 to April 2002 were analysed using the theoretical framework of logics within discourse theory. The article argues that although the Opposition succeeded in maintaining its support throughout Chávez's government, it contributed to the polarised politics that currently characterises Venezuela. 相似文献

Recreational use of the potent synthetic opioid 3,4‐ dichloro‐N‐(2‐(dimethylamino)cyclohexyl)‐N‐methylbenzamide (U‐47700) is rising, accompanied by increasingly frequent cases of serious intoxication. This article reports a case of near‐fatal U‐47700 intoxication. A man was found unconscious (with drug powder residues). After 40 h in hospital (including 12 h of supported ventilation), he recovered and was discharged. Liquid chromatography/high‐resolution mass spectrometry (LC/HRMS) or gas chromatography/mass spectrometry (GC/MS) were used to detect and quantify substances in powders, serum and urine. Powders contained U‐47700 and two synthetic cannabinoids. Serum and urine were positive for U‐47700 (351.0 ng/mL), citalopram (<LOQ), tetrahydrocannabinol (THC: 3.3 ng/mL), midazolam (<LOQ) and a novel benzodiazepine, clonazolam (6.8 ng/mL) and their metabolites but negative for synthetic cannabinoids. If potent synthetic opioids become cheaper and more easily obtainable than their classical counterparts (e.g., heroin), they will inevitably replace them and users may be exposed to elevated risks of addiction and overdose. 相似文献
