Decentralization is meant to improve access to public services, but relatively few studies examine this question empirically. We explore the effects of decentralization on access to health and education in Colombia using an original database covering over 95 % of Colombian municipalities. We show that decentralization improved enrollment rates in public schools and access of the poor to public health services. In both sectors, improving access was driven by the financial contributions of local governments. Small increases in own-shares of spending led to surprisingly large increases in the access of the poor in both sectors. Our theoretical model implies that where local information dominates productive efficiency, elected local governments will provide services better tailored to local needs. Decentralizing such services should increase their use by the public. Together, theory and empirics imply that decentralization made the Colombian state more accountable. It provided local officials with the information and incentives they need to allocate resources in a manner responsive to voters’ needs and improve the impact of public expenditures.  相似文献

This paper maps the difficulties with operationalising the gender discourse described in the peace accord and post-conflict documents, which guide Burundi's peace-building process, through local women's narratives from the security forces. The author claims that due to limited international and local investment, the local women involved in the security forces initiate small practical changes by referring to their vision of femininity, while theoretically legitimising these demands by linking them to the international human rights discourse in order to survive in an overwhelmingly masculine arena. International organisations and donors’ focus on traditionally feminine and softer areas, such as reconciliation and reintegration programmes, together with local elites’ tendency to view gender as an ‘add-on’ contribute to this development.  相似文献

Sex determination is an important task in physical anthropology and forensic medicine. The study sample comprised 121 individuals of known sex, age, and cause of death from San Jose cemetery in Granada (Spain). Eight dimensions were analyzed, and discriminant function analysis was performed for each vertebra to obtain discriminating functions and study the percentage of correct assignations of these functions. The percentage accuracy was approximately 80% for both vertebrae, but varied according to the sex, being higher for the 7th cervical in males and higher for the 12th thoracic in females. As reported in other populations, the greatest dimorphism values were found for the length of the inferior surface of the vertebral body and the width and length of the vertebral foramen of the 7th cervical vertebra and for the length of the inferior surface of the vertebral body of the 12th thoracic vertebra.  相似文献

Synthetic tryptamines have gained popularity for their hallucinogenic properties, unscheduled status, and availability from “head shops” and through the internet. Here, we present a case of synthetic tryptamine‐induced delirium secondary to 5‐MeO‐DALT ingestion in a previously healthy young male. 5‐MeO‐DALT led to the hospitalization of our patient after ingestion of a standard dose, presenting with extreme agitation, tachycardia, diaphoresis, and combativeness leading to physical restraint and intravenous sedation. A search of PubMed, Ovid, and Google Scholar for keywords of “5‐MeO‐DALT,” “5‐methoxy‐N,N‐diallyltryptamine,” or “Lucy‐N‐Nate” found no case reports or clinical articles in the literature. Rapid emergence and commercialization of this novel synthetic tryptamine 5‐MeO‐DALT points to the importance of health care and forensic professionals keeping abreast of the latest drugs of abuse and their clinical features. The authors hope this report leads the way in disseminating the potential risks associated with unscheduled and unregulated substances, synthetic tryptamines such as 5‐MeO‐DALT in particular.  相似文献

Since the beginning of recorded history, stones have been used in the commission of crimes due to their widespread availability. Stones can be used as a lethal weapon that sometimes might be the only evidence in a serious case. The common perception, even in professional fingermark circles, is that stones do not yield identifiable latent fingermarks. The authors of this research paper examined the feasibility of developing fingermarks from seven types of stones using three latent fingermark techniques: magnetic powder, cyanoacrylate fuming, and ninhydrin. The paper will demonstrate that by classifying stones and rocks according to their natural properties (porosity, permeability, and the nature of surface area), even application of the simplest development techniques can produce good results. In conclusion, chert and limestone yielded the most qualitative and quantitative results using magnetic powder. The time factor is also important in recovering latent fingermarks on stones and rocks.  相似文献

In this work, we present a measuring methodology for long bones of the limbs (humerus, femur, and tibia) of human corpses. Measurements of cadaveric height and long bone lengths were conducted on 72 corpses (20 females and 52 males) from the School of Medicine at the National Autonomous University of Mexico. Additionally, these measurements were compared with those taken from dry bones of a subsample of individuals. Our results show marginal differences (TEM% = 0.59) between cadaveric and dry bone measurements, resulting from different osteometric technical procedures. This note outlines the measuring methodology, which will be subsequently used to create regression formulas for stature estimation.  相似文献

This paper studies SMEs’ participation in public procurement in light of perceived barriers and expected benefits of accessing the public marketplace. It presents a comparative analysis of SMEs’ participation in three countries that share similar approaches to SME-friendly public procurement. A common survey protocol was developed to be administered to SMEs in the three countries. Data collected were then analysed using regression methods. Findings suggest that some issues that are typically considered critical barriers, namely administrative requirements and award based on lowest price do not hinder participation. However, findings also suggest that firms’ characteristics associated with size are still relevant hindrances, and that SMEs’ involvement are affected by a shortage of tangible (human and financial) and intangible resources (experience). These findings provide guidance to fine-tune public procurement policies directed to SMEs.  相似文献

This paper contributes to the scarce literature on government transparency by analysing the impact of political and socio-economic factors on municipal financial transparency. Our sample covers the 100 largest Spanish municipalities in 2008. Compulsory publicity and transparency are key to public management (rule-of-law theory). Our data show that Spanish municipalities are providing financial information beyond the legal requirements, thus exceeding the compulsory disclosures required by the rule-of-law theory. The more taxes and more transfers per capita, the more financial information is disclosed and, accordingly, the higher the transparency is. Therefore the municipalities are not taking advantage of fiscal illusion or principal–agent effects, since they are not concealing higher levels of taxes and transfers from citizens. Furthermore, left-wing parties are more transparent than right-wing ones. Finally, the population also has a positive effect on the achievement of financial transparency.  相似文献
