Mexico’s war on organized crime has done little to reduce people’s fear of crime and victimization

For nearly a decade, Mexico has been embroiled in a war against organized crime, with little success. But how has this often violent campaign affected people’s fears of crime and victimization? In new research, Carlos J. Vilalta uses data from Mexico’s national victimization survey, and finds that people’s daily routines have been affected by their fears about crime, with many now no longer going out at night as a result, and that this is trend that can be made worse by people’s lack of trust in the police. He writes that policy makers need to distinguish between policies to get crime under control and policies to reduce people’s fear of crime

El Mecanismo Causal del Voto de Oposición a una Obra Vial: Una exploración Espacial y Sociológica

Este estudio presenta la geografía y los mecanismos causales del voto de oposición en el plebiscito a la construcción del segundo piso del Periférico en la ciudad de México. Contiene una revisión de la literatura especializada, una descripción de la obra y el plebiscito, sus resultados, indicadores socioeconómicos, y la aplicación de diversas técnicas de estadística espacial y pruebas no paramétricas. El análisis realizado muestra la existencia de explicaciones geográficas y sociológicas sobre el voto de oposición. Geográficamente se encontró que el voto de oposición fue mayor en promedio y en varianza en la zona alrededor de la obra. Sociológicamente se encontró que las áreas de la ciudad con los mejores salarios tendieron a oponerse la construcción de la obra, mientras que las áreas con los mayores niveles de marginación tendieron a aceptarla. Se detectó una correlación negativa entre el % voto perredista para jefe de gobierno y el % de voto de oposición a la obra pero este hallazgo requiere de una mayor elaboraciónOposición política, participación social, votación, análisis estadístico, geografía política

Una Evaluación Geográfica de la Política de Educación Media Superior de la Ciudad de México

En este trabajo presentamos una evaluación geográfica de la política de las preparatorias creadas y administradas por el gobierno de la ciudad de México. La revisión teórica y evaluación estadística realizadas nos ha permitido (1) construir relaciones explicativas útiles entre varios conceptos de teorías urbanas provenientes de escuelas divergentes, y de disciplinas diferentes, y a la vez (2) hacer una demostración empírica del incumplimiento de uno de los objetivos geográficos de esta política de la ciudad de México.

Valoración de los ángulos del cuello del aneurisma de aorta abdominal. Estudio en 507 pacientes

Angulation in different planes of the neck of abdominal aortic aneurysms may be considered a limiting factor in the implantation of different prostheses in the treatment of this pathology. It is necessary to make an assessment of the angles in different planes in routine studies prior to the planning of the procedures and especially by AngioTAC. The study evaluated the measurement of 507 patients with abdominal aortic aneurysms and treated endovascular procedures and of whom the complete information was available at the level of neck angulations. In a prospective and descriptive study the situation of this aortic sector was evaluated, contributing information about the tendency in the morphological presentation of the aorta in patients with this aetiolog

Study of angulations of visceral abdominals arteries in their abdominal aorta emergency

Recently, fenestrated, branched and stent grafts have been developed in order to treat endovascular aneurysmal pathology at the level of the aorta in the emergence of the visceral arteries. For the implantation of stents, it is necessary to have a precise planimetry of the origin and orientation of the visceral branches in order firstly to perform the correct manufacture of the endoprosthesis and secondly the placement with precision of the same. The knowledge of the emergency of the vessels of the aortic wall and its orientation knowing the angle of emergency. The data obtained for the planning of the endovascular treatment of 37 patients in order to obtain data from the descriptive point of view of this sector

Characterisation of extended-spectrum b-lactamases among Klebsiella pneumoniae isolates causing bacteraemia and urinary tract infection in Mozambique

The aim of this study was to determine the prevalence of extended-spectrum β-lactamase (ESBL)-producing Klebsiella pneumoniae isolated from urinary tract and bloodstream infections in a rural hospital in Manhiça, Mozambique. ESBLs were investigated among ceftriaxone-non-susceptible K. pneumoniae clinical isolates recovered between 2004 and 2009. Characterisation of blaCTX-M, blaSHV, blaOXA and blaTEM genes was performed by PCR and sequencing. Epidemiological relationships were established by phylogenetic analysis, repetitive extragenic palindromic PCR (REP-PCR), pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST), whilst plasmid transferability was evaluated by conjugation. In addition, the presence of class 1 and 2 integrons was studied. A total of 19 K. pneumoniae were analysed. The blaCTX-M-15 gene was found in all strains. Other ESBL genes were found concomitantly, including blaSHV-5, blaSHV-2, blaSHV-2A, blaSHV-12 and blaSHV-38. In addition, other β-lactamases such as blaTEM-1 and blaOXA-30 were also detected. REP-PCR identified 15 different epidemiological profiles. MLST analysis also showed great variability of sequence types. The blaCTX-M-15 gene showed a high transfer capacity. The presence of class 1 integrons was high. High levels of multidrug resistance were also found. In conclusion, these data show the dominance of the CTX-M-type ESBL, particularly CTX-M-15, supporting its worldwide dissemination, including in areas with limited access to third-generation cephalosporins. This finding is a matter of concern for clinical management as third-generation cephalosporins are an alternative for treating severe cases of multidrug-resistant infections in this community
