Creencias de hombres de Cali, Colombia, sobre el examen digital rectal: hallazgos de un estudio exploratorio
Lucumí-Cuesta, Diego Iván;Cabrera-Arana, Gustavo Alonso;
Cadernos de Saúde Pública , 2005, DOI: 10.1590/S0102-311X2005000500022
Abstract: this study used the health beliefs model to explore beliefs on digital rectal examination (dre) to screen for prostrate cancer, prior to intent to submit to the examination, in men 45 to 64 years of age in cali, colombia. the 267 participants answered a questionnaire by means of prior selection through proportional sampling by quotas. a univariate and bivariate analysis showed that only 25.8% of the participants had submitted previously to digital rectal examination and that 68.1% intended to do so in the following 12 months. significant differences (p < 0.05) were found between a history of dre and schooling, socioeconomic status, health system coverage, perception of susceptibility to the disease, and perception of barriers and benefits. significant differences (p < 0.05) were found between intent to submit to dre and health system coverage, perception of severity of the disease, and perception of barriers. given the low level of history of dre and intent to submit to the examination, the results could help improve strategies to increase this practice at the local level.

Abstract: Usando el Modelo de Creencias en Salud se exploraron creencias sobre el examen digital rectal como tamiz para cáncer en la próstata, antecedente e intención de práctica en hombres de 45 a 64 a os de edad de Cali, Colombia. A los 267 participantes se les aplicó un cuestionario, previa selección mediante muestreo proporcional por cuotas. Después de un análisis univariado y bivariado se estableció que sólo un 25,8% de los participantes se había sometido previamente al examen digital rectal y 68,1% tenía intención de hacerlo en los siguientes 12 meses. Diferencias significativas (p < 0,05) fueron halladas entre antecedente de práctica y nivel de escolaridad, estrato socioeconómico, afiliación al sistema de salud, percepción de susceptibilidad a la enfermedad, percepción de barreras y beneficios. Se encontraron diferencias significativas (p < 0,05) entre intención de práctica y afiliación al sistema de salud, percepción de severidad de la enfermedad y percepción de barreras. Dado el bajo antecedente e intención de práctica del examen, los resultados podrían contribuir a mejorar las estrategias para incrementar su práctica a nivel local.
Costos Familiares de Mantener y Abandonar la Lactancia Exclusiva en el Primer Mes Posparto
Girón-Vargas,Sandra L.; Mateus-Solarte,Julio C.; Cabrera-Arana,Gustavo A.;
Revista de Salud Pública , 2009, DOI: 10.1590/S0124-00642009000300008
Abstract: objective estimating the difference between direct and indirect family costs arising from women who continue exclusive breastfeeding and those who abandon it during the first postpartum month. methods a cost analysis was carried out on primiparous women from cali, colombia; they were recruited during their immediate puerpery and follow-up during the first 30 postpartum days. non-parametric bootstrap techniques were used for estimating average costs and differences for 0-8, 9-30 and 0-30 postpartum days regarding women who abandoned exclusive breastfeeding and those who did not. results women who abandoned exclusive breastfeeding assumed higher costs related to baby feeding while those who continued exclusive breastfeeding had higher food costs for the mother and in contracting domestic support. conclusion the savings which a woman and her family can make due to continuing with exclusive breastfeeding become negated by the mother's food-related costs. interventions should be designed which are orientated towards prolonging exclusive breastfeeding and modifying beliefs about nutrition which contribute towards generating economic consequences for families.

Revista de Salud Pública , 2008, DOI: 10.1590/S0124-00642008000400009
Abstract: objective establishing a quality base-line as perceived by hospital users, subject to intervention by the health-service restructuring, redesign and modernisation programme. method 4 021 users were interviewed face-to-face in august 2006 from a sample of hospitals from the programme using an instrument already validated for measuring health service users’ perception of quality (pecasuss). results the interviewees (38,7 % mean age, 70 % women, 60 % affiliated to the subsided system, 55 % from stratum 1 and 53 % attended in general consultation) scored mostly as good or very good 16 different aspects perceived of the quality of services. mean user quality score was 3,98 (0,8 sd) on a score ranging from 0,0 (bad) to 5,0 (excellent). conclusions quality was generally rated as good as perceived by people using the hospital programme. the humanised treatment received from the medical staff was given the highest score regarding quality of attention received by the interviewees.
Desgaste emocional en docentes oficiales de Medellín, Colombia, 2005

Abstract: objetive exploring signs of emotional and physical weakness or burnout syndrome in qualified teachers in medellín, colombia, 2005. methods a cross-sectional study was applied to a random bi-stage sample of 239 teachers who filled in a questionnaire by themselves to explore demographic, work and social variables and dimensions of the burnout syndrome, according to the maslach burnout inventary (mbi). results the findings showed that 23,4 % of the sample presented signs of burnout and a further 23,4 % were at risk of suffering it; emotional weakness and depersonalisation were present in both subgroups. conclusions a relationship between burnout signs and some of the variables studied was found. it is suggested that personal, family and social variables potentially associated with the syndrome should be explored more deeply.
Holographic dark energy at the Ricci scale
Iván Durán,Diego Pavón
Physics , 2010, DOI: 10.1088/1742-6596/314/1/012058
Abstract: We consider a holographic cosmological model in which the infrared cutoff is fixed by the Ricci's length and dark matter and dark energy do not evolve separately but interact non-gravitationally with one another. This substantially alleviates the cosmic coincidence problem as the ratio between both components remains finite throughout the expansion. We constrain the model with observational data from supernovae, cosmic background radiation, baryon acoustic oscillations, gas mass fraction in galaxy clusters, the history of the Hubble function, and the growth function. The model shows consistency with observation.

Abstract: Purpose:An agile, adaptable and aligned (Triple A) supply chain (SC) would seem to be key to obtaining sustainable competitive advantages. Little previous research has been done into the topic, however, and there are even discrepancies on the conceptual level. For this reason this study aims to propose a reference framework to determine the dimensions and factors that define agility, adaptability and alignment in the SC and to facilitate both the evaluation of its state by managers and researchers with respect to these variables and also the development of empirical research that determines its impact on performance. Design/methodology:A systematic literature review was carried out of specialist Operations Management, Logistics, Management and Supply Chain Management journals using the ProQuest (Abi/Inform Global) database. The articles retrieved were examined and those that were relevant for this study were selected. Using these, a qualitative analysis was done that led to the proposed goal being achieved. Findings: This study sets out the definitions, dimensions and factors of the three variables and groups them together for the first time, thus providing a solid conceptual frame. Although the number of articles that analyse one or other of the variables is growing, it is still low. Agility is the variable on which most research has been done, while adaptability is the least analysed. Research limitations/implications:A theoretical reference framework is proposed for the Triple A in the SC based on earlier studies which do not discuss the joint effect of three variables, as a result of which there is no tested theoretical base. The model will be analysed empirically in future research. Originality/value:The lack of papers on agility, adaptability and alignment in the supply chain and the lack of a consensus regarding the dimensions and factors to define them reveal a need for studies such as this.

Observational constraints on a holographic, interacting dark energy model
Iván Durán,Diego Pavón,Winfried Zimdahl
Physics , 2010, DOI: 10.1088/1475-7516/2010/07/018
Abstract: We constrain an interacting, holographic dark energy model, first proposed by two of us in [1], with observational data from supernovae, CMB shift, baryon acoustic oscillations, x-rays, and the Hubble rate. The growth function for this model is also studied. The model fits the data reasonably well but still the conventional $\Lambda$CDM model fares better. Nevertheless, the holographic model greatly alleviates the coincidence problem and shows compatibility at $1\sigma$ confidence level with the age of the old quasar APM 08279+5255.
