Speed Dating y el mercado de solteros

Encontrar tu media naranja ocupa recursos, es un hecho crucial en el ser humano ser capaz de optimizarlos y hacer una elección que, como demostraremos, es racional aunque parezca que el amor sea ilógico.Considerando los posibles candidatos parte de la oferta y/o la demanda, los economistas crean modelos para explicar un mercadomatrimonial en el que la base de estudio son los clientes de Speed Dating, un sistema de citas rápidas. Siendo ésta la base principal,nuestro objetivo es realizar un proyecto en el que seamos capaces de establecer un prototipo de cliente, tanto femenino como masculino observando los posibles sesgos que tal población pueda mostrar para estudios de inferencia estadística sobre la población de los solteros.Las diferencias entre sexos son una motivación esencial, preguntarnos si puede marcar una diferencia en el punto de partida también. Éstas y demás preguntas las resolveremos en las siguientes páginas, ¿sabéis que en realidad nos unen más aspectos que el estado civil?, ¿no essospechoso que seamos aparentemente tan iguales?Si realmente la guerra de sexos existe aquí demostramos que avanzamos en aras de la igualdad: Los solteros del Speed Dating tienen altos niveles de estudios, dedican su tiempo de ocio a actividades culturales y de entretenimiento y disponen de una mentalidad abierta.La paz es posible pero no deja de implicar la incertidumbre sobre si una diferencia es positiva o negativa, cuestiones morales a parte. Si los candidatos de un sexo determinado superan al contrario, es lógico que, al haber mayor competencia busquen la diferenciación como ventaja comparativa para acceder a mejores términos de comercio, así que si no existe tal diferencia puede ser por dos motivos: realmente la igualdad impera en la sociedad como estudios sociológicos determinan, resaltando la homogamia, concepto propio de un mercado matrimonial “sin restricciones” o quizás, la heterogamia en las uniones está quedando en segundo lado, perdiendo en términos de apertura social.

Desempenho motor de idosos do Nordeste brasileiro: diferenças entre idade e sexo

O objetivo deste estudo foi identificar o desempenho motor, de acordo com o sexo e o grupo etário, em idosos residentes em comunidade do Nordeste brasileiro. Trata-se de estudo transversal que analisou dados de 316 idosos de uma pesquisa epidemiológica de base domiciliar e populacional realizada em janeiro de 2011. Participaram do estudo 173 mulheres (54,7%) e 143 homens com idade média de 74,2 (± 9,8 anos). As mulheres apresentaram maior declínio funcional com o avanço da idade e mais limitação funcional em testes de força/resistência de membros inferiores e locomoção. Em ambos os sexos, a prevalência de limitação funcional foi mais elevada nos grupos etários de 70-79 anos e > 80 anos, com as mulheres apresentando mais limitação a partir dos 70 anos e os homens, a partir dos 80 anos. Os dados desta pesquisa podem subsidiar o planejamento de medidas para prevenção, manutenção ou melhora da limitação funcional em idosos, proporcionando maiores cuidados integrados.

Obesity and overweight associated with lower rates of colorectal cancer screening in Switzerland.

Screening for colorectal cancer (CRC) is associated with reduced CRC mortality, but low screening rates have been reported in several settings. The aim of the study was to assess predictors of low CRC screening in Switzerland. A retrospective cohort of a random sample of 940 patients aged 50-80 years followed for 2 years from four Swiss University primary care settings was used. Patients with illegal residency status and a history of CRC or colorectal polyps were excluded. We abstracted sociodemographic data of patients and physicians, patient health status, and indicators derived from RAND's Quality Assessment Tools from medical charts. We defined CRC screening as colonoscopy in the last 10 years, flexible sigmoidoscopy in the last 5 years, or fecal occult blood testing in the last 2 years. We used bivariate and multivariate logistic regression analyses. Of 940 patients (mean age 63.9 years, 42.7% women), 316 (33.6%) had undergone CRC screening. In multivariate analysis, birthplace in a country outside of Western Europe and North America [odds ratio (OR) 0.65, 95% confidence interval (CI) 0.45-0.97], male sex of the physician in charge (OR 0.67, 95% CI 0.50-0.91), BMI 25.0-29.9 kg/m (OR 0.66, CI 0.46-0.96) and at least 30.0 kg/m (OR 0.61, CI 0.40-0.90) were associated with lower CRC screening rates. Obesity, overweight, birthplace outside of Western Europe and North America, and male sex of the physician in charge were associated with lower CRC screening rates in Swiss University primary care settings. Physician perception of obesity and its impact on their recommendation for CRC screening might be a target for further research.

Greenstick fractures of the middle third of the forearm. A prospective multi-centre study.

BACKGROUND: Greenstick fractures suffered during growth have a high risk for refracture and posttraumatic deformity, particularly at the forearm diaphysis. The use of a preemptive completion of the fracture by manipulation of the concave cortex is controversial and data supporting this approach are few. AIM: Aim of this study was to determine the factors which predispose to refracture and deformities, and to define therapeutic strategies. METHODS: We prospectively gathered clinical and radiographic data over a period of one year on greenstick fractures of the middle third of the forearm in children as part of a multi-centre study. Endpoint was a follow-up visit at one year. Radiographic deformity, state of consolidation at resumption of physical activities and refracture rate were analysed statistically (ANOVA, Student's t-test and Pearson's chi-square test) with regard to patient age, gender, fracture type, therapy and time in plaster. RESULTS: We collected the data of 103 patients (63 boys, 40 girls), average age 6.6 years (1.3-14.5 years), the vast majority of whom had a combined greenstick fracture of the radius and ulna. 6.7% of the patients sustained a refracture within 49 days (29-76) after plaster removal. They were significantly older (p=0.017) with a significantly higher incidence of manual completion of the fracture with radiographic signs of partial consolidation (p=0.025). Residual deformities were significantly smaller after completion of the fracture compared to reduction without completion (p=0.019) or plaster fixation alone (p<0.005). CONCLUSIONS: Completion of a greenstick fracture does not prevent refracture. Nevertheless, it diminishes the extent of secondary deformities in cases where the primary angulation exceeds the remodelling capacity. Prevention of refracture should include a routine radiographic follow-up 4-6 weeks after injury with continuation of plaster fixation in cases of partial consolidation.

Los Puertos Francos y las economías insulares atlánticas

La comunicación que se presenta analiza los factores que determinan la evolución económica de las islas atlánticas euroafricanas, tomando como ejemplo Canarias y Cabo Verde. Se constata que, mientras en las primeras los Puertos Francos certificaron las relativas libertades económicas y, junto con otros factores, facilitaron el crecimiento económico, en Cabo Verde, a pesar de disponer de una situación geográfica favorable, el exceso de imposición y los monopolios dificultaron ese crecimiento.

Ethics outside, within or beyond OR models

Since ethical concerns are calling for more attention within OperationalResearch, we present three approaches to combine Operational Researchmodels with ethics. Our intention is to clarify the trade-offs faced bythe OR community, in particular the tension between the scientificlegitimacy of OR models (ethics outside OR models) and the integrationof ethics within models (ethics within OR models). Presenting anddiscussing an approach that combines OR models with the process of OR(ethics beyond OR models), we suggest rigorous ways to express the relationbetween ethics and OR models. As our work is exploratory, we are trying toavoid a dogmatic attitude and call for further research. We argue thatthere are interesting avenues for research at the theoretical,methodological and applied levels and that the OR community can contributeto an innovative, constructive and responsible social dialogue about itsethics.
