This article presents both a theoretical framework and a methodology that attempt to capture the complex interactions among labor markets, families, and public policy that currently constitute Latin American welfare regimes. Drawing on cluster analysis based on available data for 18 countries, the study identifies three welfare regimes. Two are state welfare regimes: protectionist (e.g. Costa Rica) and productivist (e.g. Chile); one is nonstate familiarist (e.g. Ecuador and Nicaragua). In a region where people's well‐being is deeply embedded in family relationships, closer scholarly attention to how social structures interact with public policy bears not only academic interest but also policy implications, particularly for adapting particular welfare regimes to the local welfare mix. 相似文献

Empirical evidence that migrants send home more remittances after disasters raises the question of whether remittances are used to self-insure, substituting for both formal and informal insurance. We investigate this question using a unique data set on the usage patterns of financial services by households in South Africa. We show that the likelihood that a respondent has a formal funeral cover increases with income and banking status. However, it is lower for individuals receiving remittances, which supports the idea that remittances act as self-insurance. We also show that other risk management strategies influence the purchasing of formal funeral cover. Finally, we find that determinants of informal insurance differ from those of formal insurance. 相似文献

POPULATION: We have analyzed the distribution of the allele frequencies and parameters of forensic interest at nine short tandem repeat (STR) loci (CSF1PO, D3S1358, D5S818, D7S820, D13S317, FGA, TH01, TPOX, and vWA) in a sample population of 165 unrelated individuals from César and Guajira, Caribbean populations of Colombia. 相似文献

The purpose of this paper is to determine how NAFTA influenced the Mexican tourism sector and its effects on the environment.
The linkage between the tourism sector and NAFTA is done through the analysis of foreign direct investment and cross-border
trade in services. The quantitative section of the paper focuses on analyzing commercial presence in the form of hotels and
restaurants, as well as the use of services abroad. The paper concludes that NAFTA represented greater certainty to investors
but was not the main driver behind the investments in tourism services. The analysis of visitors from US and Canada in Mexico
recognizes that NAFTA did not have significant impact on the tourism flow. NAAEC, on the other hand, serves in this research
as a qualitative connection between tourism sector and the environment for attending to citizen submissions on failures in
environmental law enforcement in Mexico regarding tourism projects. It is included with an economic-environmental balance
in Cancun—which shows that the greatest environmental impact is of global importance: CO2 released into the air by air transportation, followed by the local impact of water consumption, waste generation, and electricity
usage, in that order. 相似文献

An improved version of the famous Molotov cocktail is the Chemical Ignition Molotov Cocktail (CIMC). This incendiary device contains chemical reagents that enable its self-ignition. The analysis of anions from CIMC residues by capillary electrophoresis (CE) allows the identification of the reagents used to produce the device, and provides forensic analysts with valuable information. Although, sulfate, chlorate, chloride, and perchlorate anions have been recently proposed in the literature as target anions to determine the CIMC composition, the identification of some of them could be controversial due to their presence in the environment. Therefore, the purpose of this study was to identify highly reliable anions capable of indicating the components used to prepare these self-initiated devices. The relationship among the detected anions in CIMC residues and the reagents employed in their elaboration is discussed. Some anions have been proposed as anionic markers of CIMC as incendiary devices. Additionally, the viability of different CIMC compositions was studied. 相似文献

A rapid and highly species-specific real-time polymerase chain reaction (PCR) assay has been developed for the detection of capercaillie DNA (Tetrao urogallus) in meat and meat mixtures. The method combines the use of capercaillie-specific primers, that amplify a 142bp fragment of the mitochondrial 12S rRNA gene, and a positive control primer pair that amplifies a 141bp fragment of the nuclear 18S rRNA gene from eukaryotic DNA. SYBR(?) Green dye or TaqMan(?) fluorogenic probes were used to monitor the amplification of the target genes. Results obtained with the use of TaqMan(?) probes as detection platform increased the specificity of the real-time PCR assay in comparison with the results obtained using SYBR(?) Green. The proposed real-time PCR assay represents a rapid and straightforward method for the accurate identification of capercaillie that could be used by law enforcement agencies as a tool for the control of poaching and illegal trade of meat from this protected species. 相似文献

The "coffin fly,"Conicera tibialis Schmitz (Order: Diptera, Family: Phoridae), is well known for its frequent occurrence on buried corpses, in some cases after postmortem intervals of even 3-5 years. The present report describes the presence of a large amount of individuals of C. tibialis inside the coffin of a buried human corpse exhumed 18 years after death in central Spain. Adults, some of them newly emerged, and empty puparia were found in connection with the remains. Such postmortem interval is significantly longer than previously known for this species and raises the question on the current state of knowledge about the use of insects for estimating the postmortem interval in old, buried remains. 相似文献
