Estudio diagnóstico de la influencia de los programas de cultura ciudadana de la alcaldía mayor sobre algunos indicadores de movilidad en Bogotá, periodo 1995-2004

El interés por desarrollar el tema de cultura ciudadana y su influencia sobre los indicadores de movilidad referidos a la accidentalidad, surge a partir de una percepción de éxito de tres alcaldías que lograron transformaciones culturales y físicas en Bogotá. El propósito era comprobar a partir de un análisis cuantitativo que la cultura ciudadana funcionó como herramienta de gestión y que había logrado afectar positivamente las crecientes tasas de accidentalidad vial en Bogotá, durante dichas alcaldías (1995-2004). Sin embargo, la caracterización de la cultura ciudadana referida a la accidentalidad vial, tenía un alto componente cualitativo que permitió comprender que las estadísticas no se podían asociar directamente a las estrategias de cultura ciudadana y que por lo tanto, la investigación debía concentrarse en dimensionar la capacidad real que tenían las acciones de cultura ciudadana sobre el problema urbano, desagregando las dos variables.

Hacer ciudad en la gran ciudad: el desafío del Distrito Federal

Durante años, el Distrito Federal no contempló en su modelo de ciudad el espacio público como una prioridad. La base para crear el espacio público es el suelo y en el Distrito Federal este es un grave problema, pues nos enfrentamos a un suelo privatizado al cual no se le da tratamiento de bien público y existen grandes inequidades en la distribución del espacio público en la ciudad. No obstante, ya se reconoció en el gobierno del D.F. la importancia del problema, aunque es indispensable concretar esa preocupación en proyectos específicos y aún más desarrollar algunos instrumentos para poder ejecutar las obras necesarias. ¿Qué es espacio público? ¿Qué grupos sociales afecta? ¿Para qué función urbana? Son preguntas claves que se constituyen en el núcleo de la formulación de la política. Es necesario redimensionar el problema a partir de la definición misma de un modelo de ciudad, dándole a la problemática una perspectiva territorial que le permita cumplir la función social, establecer una normatividad clara y vigente, una política de suelo transformadora y conservacionista, dotar con instrumentos financieros viables y asumir un liderazgo capaz de sobrepasar los intereses particulares.---Building a city within the big city: Mexico City’s challengerFor years Distrito Federal in Mexico not covered by the model of city public space as a priority. The basis for creating public space is the ground and in Distrito Federal this is a serious problem. We face a privatized land which no treatment is given public good. There are great inequities in the distribution of public space in the city. Already City Government recognized the importance of the problem although it is essential to landing that concern specific projects, but more so to develop some tools to execute the necessary works. What public space? Which social groups affected? What urban function? There are key questions that are in the trunk of policy formulation. Doing nothing does not seem the best option given the scale of the problem, and therefore it becomes necessary to resize the problem from the very definition of a city model giving the issue a territorial perspective to discharge social function, the establishment providing a clear and current land policy processing and preservation, financial instruments, and a leadership capable of overcoming special interests. Key words: Public space, privatized land, inequity, urban function, city model, rules.---Fazer cidade na grande cidade: o desafio do Distrito FederalDurante anos, o Distrito Federal não contemplou em seu modelo de cidade o espaço público como uma prioridade.

PTPN22 Association in Systemic Lupus Erythematosus (SLE) with Respect to Individual Ancestry and Clinical Sub-Phenotypes

Protein tyrosine phosphatase non-receptor type 22 (PTPN22) is a negative regulator of T-cell activation associated with several autoimmune diseases, including systemic lupus erythematosus (SLE). Missense rs2476601 is associated with SLE in individuals with European ancestry. Since the rs2476601 risk allele frequency differs dramatically across ethnicities, we assessed robustness of PTPN22 association with SLE and its clinical subphenotypes across four ethnically diverse populations. Ten SNPs were genotyped in 8220 SLE cases and 7369 controls from in European-Americans (EA), African-Americans (AA), Asians (AS), and Hispanics (HS). We performed imputation-based association followed by conditional analysis to identify independent associations. Significantly associated SNPs were tested for association with SLE clinical sub-phenotypes, including autoantibody profiles. Multiple testing was accounted for by using false discovery rate. We successfully imputed and tested allelic association for 107 SNPs within the PTPN22 region and detected evidence of ethnic-specific associations from EA and HS. In EA, the strongest association was at rs2476601 (P = 4.761029, OR = 1.40 (95% CI = 1.25–1.56)). Independent association with rs1217414 was also observed in EA, and both SNPs are correlated with increased European ancestry. For HS imputed intronic SNP, rs3765598, predicted to be a cis-eQTL, was associated (P = 0.007, OR = 0.79 and 95% CI = 0.67–0.94). No significant associations were observed in AA or AS. Case-only analysis using lupus-related clinical criteria revealed differences between EA SLE patients positive for moderate to high titers of IgG anti-cardiolipin (aCL IgG .20) versus negative aCL IgG at rs2476601 (P = 0.012, OR = 1.65). Association was reinforced when these cases were compared to controls (P = 2.761025, OR = 2.11). Our results validate that rs2476601 is the most significantly associated SNP in individuals with European ancestry. Additionally, rs1217414 and rs3765598 may be associated with SLE. Further studies are required to confirm the involvement of rs2476601 with aCL IgG.

Characterization of resistance in vitro to different antimicrobial in strains of Staphylococcus spp. in a hospital of the city of Valledupar between January and July 2009

The Staphylococcus spp. they can cause a wide range of infections systemic and located in community and hospital patients. Its high pathogenicity and growing resistance to multiple antimicrobials including methicillin, causes high morbiditymortality rates, causing a high epidemiological impact. Objective: to determine the phenotypic profile of resistance to different antimicrobials in strains of the genus Staphylococcus spp. Materials and methods: collected 75 strains and determined them susceptibility to different antibiotics by the Kirby-Bauer method. The production of betalactamasecheck using the nitrocefin test. (Resistance to Methicillin in S. aureus was conductedusing Mueller Hinton with 4% NaCl and oxacillin 6 μg/mL). Inducible clindamycin resistance tamizo by D-Test test. Results: they were isolated by 38% of staphylococcus coagulase negative (SNA) and 62% of S. aureus. 53% were penicillin resistant staphylococci: S. aureus with 58% and 42% SNA. 47% of the strains showed resistance to methicillin: S. aureus with 61% and SNA with 39%. A strain of S. aureus showed inducible resistance to clindamycin (1.33%). Coagulase negative staphylococci were isolated mostly from blood samples (31%), blood (29%), tip of catheter (5%) and came mostly from neonatal ICU (25%), medical (21%) and surgery (16%).Conclusions: S. aureus and SNA were isolated with greater frequency in blood and wounds from surgery and neonatal ICU. The predominant resistance phenotypes were penicillin and oxacillin.

Physical Exercise Program for Elderly Subjects in the “Club Nueva Vida”, in Tunja City

A descriptive, case series intervention study was performed to identify changes in physical qualities, aerobic power, flexibility, strength and body composition amongst 20 elderly subjects belonging to the “Club Nueva Vida” in Tunja City, during the second period of 2005. A PRE and POST assessment of their physical qualities was applied after a 16 week physical exercise program.Results showed an increase in the average of the static muscle streneth from 0.27 to 0.30 Newtons. Standard deviation diminished in 0.1. The dynamic strength measure by the push up test improved in 10% a 35% improved in 10% a 35% improved their. Cardiovascular capability until to high levels of 80% there were not significant changes in the body weight between measures taken before and after the program application. The results obtained with the sit and reach test did not show statistically significant differences. Hower in other flexibility tests the results changed from bad ranges to middle and good ones. The enrolled population was stable during the development of the exercise program. This study concludes that elderly adults acquire changes in their physical quality features after exercise intervention. Physical exercise programs in elderly adults must involve strength activities for upper limbs, trunk and aerobic power activities. The “Beliefs Health Model” is a adherence to reach compliance and maintenance in physical exercise.

Actions of resiliencia opposite to the housing policies in the city of Buenos Aires, Argentina: the social organizations, the institutions, and the massive evictions

The current housing problems in the city of Buenos Aires revolves around two phenomena, the precariousness and the evictions, in a context that is conceived like housing emergency. In response to this situation, some institutional organisms and certain social organizations with territorial roots in the south of the city, began to take forward actions of resilience opposing to the massive evictions, which take place as consequence of the real-estate pressure, and were concerning to the hotels, pensions, tenancies, and usurped houses of this zone of the city. It will be analyzed the actions of resilience displayed by them in their individual and collective dimensions and their relation to housing policies.

Women, rights and the city: notes for the construction of a state of art from the feminist thought and theory

The modern citieshave been born of the processes of industrialization, urbanization, which have been characterized by violence, resulting in social inequality, spatial segregation, the struggle for survival, the authoritarianism of the government and the establishment of exclusive orders genre, which has  prevented the enjoyment of the rights differential. In order to understand these complexities and  transform power relations that develop and reproduce it, this article analyzes the main theoretical  contributions and methodological approaches that feminist and gender studies have been conducted on the city, urban space and the right to city, which are valuable contributions to the definition of  the right to the city of women as a collective right to universal construction

The City Passing by the River. The San Francisco River Canalization and Construction of Avenida Jiménez de Quesada in Bogota at the Beginning of the 20th Century

The document refers to the San Francisco river canalization and subsequent construction of the Avenida Jiménez de Quesada. Understanding that the project was ascribed to the modernizing policy of the time, the investigation identifies the different stages in the canalization process, and shows its relations with the spatial structure of the city and the local conditions that developed on the river surroundings. The financing of the project through the “property increase duty” permits an illustration of the progress of canalization and construction of the Jiménez Avenue process, providing a less technical and more social meaning to the sequence in which the project executed. Consequently, the document approaches the shaping dynamics of Bogotá´s spatial structure at the beginning of the XX century.

Interaction between Public Transportation and Urbanization in the Mexico City Metropolitan Area: an Expansive Model Reaching its Limits

In Metropolitan Area of Mexico City, most of urban displacements happen through semi formal public transportation: small and medium capacity vehicles operated by small private enterprises, through a concession scheme. This kind of public transportation has been playing a major role in the Mexican capital. On one hand, it has been one of the conditions for urbanization to be possible. On the other hand, despite its uncountable deficiencies, public transportation has allowed for a long time the whole population to be able to move within this huge metropolis. However, that important function with regards to integration has now reached its limits in the most recent suburbs of the city, where a new mode of urbanization is taking place, based on massive production of very big social housing gated settlements. Public transportation tends to constitute here a factor of exclusion and households meet with important difficulties for their daily mobility. 

Informality in the City: a Theoretical Analysis

This thesis theoretically studies the relationship between the informal sector (both in the labor and the housing market) and the city structure.

Caracterización de los hábitos alimentarios en población pediátrica de cuatro instituciones escolares

Introducción: La obesidad infantil ha venido en aumento en los últimos años y Colombia no es ajena a esta problemática. Uno de los lugares para intervención son los planteles educativos, en los cuales los escolares son quienes escogen sus alimentos. En el presente estudio se pretendió caracterizar los hábitos alimentarios de una población pediátrica en cuatro instituciones educativas, con el fin de conocer las prioridades infantiles en cuanto a la escogencia de los alimentos, y por ende generar recomendaciones. Metodología: Se realizó un estudio descriptivo multicéntrico que presenta los resultados de encuestas dirigidas a escolares entre 8 y 18 años, usuarios de tiendas escolares. Se realizó un análisis descriptivo de acuerdo a las preferencias de alimentación por institución, por género y por edad entre otros. Resultados: Se incluyeron un total de 512 escolares. La distribución por género y edad fue similar en las cuatro instituciones educativas. Entre los alimentos de preferencia predominaron los alimentos empaquetados, pizza, helados y en menor proporción las frutas. En cuanto a las bebidas predominó la gaseosa y té en botella. Entre las razones para escoger los alimentos predominó “el sabor” seguido de la “facilidad y rapidez” para su consumo; y la principal razón para no escoger los alimentos fue el precio. Discusión: Es necesario hacer intervención desde una temprana edad para generar hábitos de alimentación saludable y equilibrada, al igual que se debería tener un programa de detección de hábitos alimentarios inadecuados en las instituciones escolares para así poder combatirlos.
