Abstract: introduction: the relationship between a country's economic development and its fatality rate from motor vehicle accidents (mva) has not been studied according to the different types of users of public thoroughfares. methodology: this article presents a cross analysis of recent mortality data from 44 countries through the use of information found in the death certifications supplied by the world health organization. results: for five types of users of public roadways the mortality rate by mva is presented as deaths per 100,000 inhabitants and deaths per 1000 motor vehicles. economic development is measured by the per capita gdp (gross domestic product) in us dollars and the number of motor vehicles per 1000 inhabitants. the results showed that the total mortality rate by mva in low income countries reached a peak at a gdp of around us $2000 per capita and around 100 motor vehicles per 1000 inhabitants. conclusions: the overall mortality rate diminished with the increase of national income at around us $24,000. the majority of the changes in fatality by mva in association with economic development were explained by changes in the number of nonmotorized users of public ways, especially pedestrians. the total number of mva was reduced when the exposure of pedestrians to motorized traffic was lower either because there were fewer motor vehicles or because there were fewer pedestrians. the rate was higher during critical periods of transition towards more motorized transportation when many pedestrians and other non-motorized users of public thoroughfares were competing for space with increased numbers of motorized vehicles.

Medina,Yliana Rojas; Espitia-Hardeman,Victoria; Dellinger,Ann M.; Loayza,Manuel; Leiva,Rene; Cisneros,Gloria;
Revista Panamericana de Salud Pública , 2011, DOI: 10.1590/S1020-49892011000300007
Abstract: a national hospital-based nonfatal road traffic injury surveillance system was established at sentinel units across peru in 2007 under the leadership of the ministry of health. surveillance data are drawn from three different sources (hospital records, police reports, and vehicle insurance reports) and include nonfatal road traffic injuries initially attended at emergency rooms. a single data collection form is used to record information about the injured, event characteristics related to the driver of the vehicle(s), and the vehicle(s). data are analyzed periodically and disseminated to all surveillance system participants. results indicated young adult males (15-29 years old) were most affected by nonfatal road traffic injuries and were most often the drivers of the vehicles involved in the collision. four-wheeled vehicle occupants comprised one-half of cases in most regions of the country, and pedestrians injured in the event accounted for almost another half. the system established in peru could serve as a model for the use of multiple data sources in national nonfatal road traffic injury surveillance. based on this study, the challenges of this type of system include sustaining and increasing participation among sentinel units nationwide and identifying appropriate prevention interventions at the local level based on the resulting data.

Salud Pública de México , 2008, DOI: 10.1590/S0036-36342008000700011
Abstract: objective: describe the impact of interventions focused on decreasing deaths by motorcycle crash. material and methods: we analyzed variations in deaths by motorcycle crash in cali when the interventions were implemented and the statistical significance of changes between 1993 and 2001. results: the rate of motorcyclist deaths per 100 000 inhabitants decreased from 9.7 in 1995 to 3.6 in 2001. the greatest reduction was observed after the introduction of the helmet law for motorcycle drivers in 1996 (12.3%). other interventions-such as a helmet law for passengers, a reflective safety vest, a circulation ban for motorcyclists in december, and compulsory courses for all motorcyclists-produced a greater decrease in mortality; meanwhile, a lack of law enforcement increased it. conclusions: the establishment and implementation of a combination of prevention strategies was more effective than a single or non-articulated strategy.
Quark matter influence on observational properties of compact stars
Hardeman, Sjoerd
High Energy Physics - Phenomenology , 2008, DOI: 10.1016/j.nuclphysa.2009.01.052
Abstract: Densities in compact stars may be such that quarks are no longer confined in hadrons, but instead behave as weakly interacting particles. In this regime perturbative calculations are possible. Yet, due to high pressures and an attractive channel in the strong force, condensation of quarks in a superfluid state is likely. This can have interesting consequences for magnetic fields, especially in relation to the discovery of slow-period free precession in a compact star. In this proceedings there will be a discussion of the mass-radius relations of compact stars made from quark matter and magnetic field behaviour in compact stars with a quark matter core.
Consistent Decoupling of Heavy Scalars and Moduli in N=1 Supergravity
Ana Achucarro,Sjoerd Hardeman,Kepa Sousa
Physics , 2008, DOI: 10.1103/PhysRevD.78.101901
Abstract: We consider the conditions for integrating out heavy chiral fields and moduli in N=1 supergravity, subject to two explicit requirements. First, the expectation values of the heavy fields should be unaffected by low energy phenomena. Second, the low energy effective action should be described by N=1 supergravity. This leads to a working definition of decoupling in N=1 supergravity that is different from the usual condition of gravitational strength couplings between sectors, and that is the relevant one for inflation with moduli stabilization, where some light fields (the inflaton) can have long excursions in field space. It is also important for finding de Sitter vacua in flux compactifications and KKLT scenarios, since failure of the decoupling condition invalidates the implicit assumption that the stabilization and uplifting potentials have a low energy supergravity description. We derive a sufficient condition for supersymmetric decoupling, namely, that the Kahler invariant function G = K + log |W|^2 is of the form G = L(light, (heavy)) with H and L arbitrary functions, which includes the particular case G = L(light) + H(heavy). The consistency condition does not hold in general for the ansatz K = K(light) + K(heavy), W = W(light) + W(heavy) and we discuss under what circumstances it does hold.
Motivación laboral y clima organizacional en empresas de telecomunicaciones: factores diferenciadores entre las empresas pública y privada
Chaparro Espitia,Leovany;
Innovar , 2006,
Abstract: the present study arose from a research carried out in bogotá's telecommunications sector, which was orientated towards describing and comparing motivational factors and their relationship to the organizational climate concerning employees from both a public and a private company. the results were analysed by comparing the means from different motivational factors and work climate dimensions regarding some demographic variables. these served as a point of comparison, contrast or affinity for describing and analysing both companies' work motivation and organisational climates. it was concluded that there were no significant differences regarding work climate and motivation of public and private company workers in the telecommunications sector, contrasting with the popular belief that there is relatively low commitment in state companies. there could be cultural and legal differences.
TRANSFORMACIONES HISTóRICAS DEL MOVIMIENTO SOCIAL SIN TIERRA DEL BRASIL Y SU RELACIONAMIENTO CON MOVIMIENTOS SOCIALES DE LATINOAMéRICA
Espitia Caicedo,Nessdy;
Papel Politico , 2006,
Abstract: this article is a summary of a extensive investigation of a master's thesis. the general objective of which was the description of the historical transformations of the social movement, "sin tierra" of brazil (mstb) and its relationship with others social actors, in order to determine the influence of its activities as a social group in latin america in the context of globalisation. this study is evidences that the mstb has responded to the challenges of globalization and the increase in disputes in latin america, through the use of social coalitions, the acquisition of moderate political and social power and opposition to the brazilian government which demonstrates its potential as an anti-hegemonic group. the combination of resistance strategies, the formation of political ideology, social mobilisation, solidarity and public opinion, has ensured the sustainability of the movement and, facilitated the identification of the constitutive elements of not only a traditional social movement but as a new social movement which illustrates the multidimensions of social movements in latin america. finally, the construction of a theoretical eclectic framework on modern social movements promotes a better understanding of the transformations and examines them in an unfavorable political contexts with respect to collective action.
Dictadura, “estado de sitio” y provocatio ad populum en la obra de Mommsen
Fabio Espitia Garzón
Revista de Derecho Privado , 2011,
Abstract: En esta contribución el autor vuelve al emblemático R misches Staatsrecht (Derecho Público Romano) de Mommsen, para establecer en qué medida, al abordar los temas de la dictadura y la provocatio ad populum, el imponente jurista alemán también adoptó la ideología burguesa, y al hacerlo sobrepuso ideas y esquemas extra os a las concepciones romanas, desconociendo la especificidad de las distintas atribuciones otorgadas en la dictadura romana. El autor indica que la visión de la dictadura romana de Mommsen refleja la concepción que sobre la misma tuvo ya Montesquieu, desconociendo que esta magistratura era una summa potestas limitada que sólo en algunos casos supuso ejercicio discrecional de la represión criminal, de allí la fácil confusión con la tiranía como forma de gobierno, propia del pensamiento burgués. Así mismo, el autor se ala que la reconstrucción de Mommsen desconoce también a Maquiavelo, quien aseveraba que nunca ningún dictador causó a la república más que beneficios, y resaltaba su temporalidad y limitados poderes, y a Rousseau, quien recordaba que un dictador podía en ciertos casos suspender las libertades públicas sin poder nunca atentar contra ellas.
