The role of emotion, values, and beliefs in the construction of innovative work realities

Traditional approaches to requirements elicitation stress systematic and rational analysis and representation of organizational context and system requirements. This paper argues that (1) for an organization, a software system implements a shared vision of a future work reality and that (2) understanding the emotions, feelings, values, beliefs, and interests that drive organizational human action is needed in order to invent the requirements of such a software system. This paper debunks some myths about how organizations transform themselves through the adoption of Information and Communication Technology; describes the concepts of emotion, feeling, value, and belief; and presents some constructionist guidelines for the process of eliciting requirements for a software system that helps an organization to fundamentally change its work patterns.(undefined

Prevalencia de actividad física y su relación con variables sociodemográficas y ciertos estilos de vida en escolares cordobeses

BACKGROUND: Regular physical exercise is not a widespread habit among the population. Early childhood in a crucial stage for acquiring this habit. The objective of this study was that of ascertaining the behavior of school-age children with regard to the degree of physical activity they do and to examine the factors involved. METHODS: An observational study was conducted by means of a survey based on a questionnaire which 6th and 8th grade students in a Basic Health Care District of Cordoba (N-585) filled out on their own. Questions were asked regarding the frequency of exercise, preferences and prospects for practicing sports, the children’s physical shape and school physical education classes, in addition to other behavior comprising their lifestyles. A dual-variable (p<0.05) and a multiple-variable analysis was conducted employing logistic regression. RESULTS: A total of 548 students filled out the survey (response rate=97.8%). 79.3% (IC95% 75.7-82.6) were involved in extracurricular physical activities, 21.0% (IC95% 17.1-24.7%) being involved in intense physical exercise. 50.5% (IC95% 46.3-54.8) did not think that they were in good physical shape. The age, sex, type of residence, the involvement in sports on the part of their parents or a close friend and what they considered their degree of healthiness to be comprised the variables quite strongly linked to doing exercise (p<0.001). CONCLUSIONS: The prevalence of physical exercise is high, although it progressively decreased with age, especially for girls. A major number of students considered themselves to be in unsatisfactory physical condition.FUNDAMENTO: El ejercicio físico regular es una práctica poco extendida entre la población. La infancia es una etapa crucial para adquirir este hábito. El objetivo del estudio fue conocer la conducta de los escolares respecto al grado de actividad física que desarrollan y examinar los factores que se relacionan. MÉTODOS: Se llevó a cabo un estudio observacional mediante encuesta basada en un cuestionario autoadministrado a los escolares de 6º y 8º de Enseñanza General Básica de una Zona Básica de Salud de Córdoba (N=585). Se interrogó sobre la frecuencia de ejercicio, preferencias y expectativas para la práctica deportiva, estado de forma física y clases de educación física del colegio, además de otras conductas constitutivas de los estilos de vida. Se llevó a cabo un análisis bivariado (p<0,05) y multivariado con aplicación de regresión logística. RESULTADOS: Contestaron la encuesta un total de 548 alumnos (tasa de respuesta=97,8%). El 79,3% (IC 95%: 75,7-82,6) realizaban actividades físicas extraescolares, y el 21,0% (IC 95%: 17,7-24,7) ejercicio físico intenso. El 50,5% (IC 95%: 46,3-54,8) no consideran bueno su estado de forma física. La edad, el sexo, el tipo de residencia, la práctica deportiva en los padres o el amigo y estado de salud percibido constituyen las variables más fuertemente asociadas a la realización de ejercicio (p<0,001). CONCLUSIONES: Aunque la prevalencia de ejercicio físico es elevada, va declinando con la edad, sobre todo en las niñas. Un importante número de escolares consideran insatisfactorio su estado de forma física

Relative Sea-Level Rise Around East Antarctica During Oligocene Glaciation

During the middle and late Eocene (∼48-34 Myr ago), the Earth\u27s climate cooled1,2 and an ice sheet built up on Antarctica. The stepwise expansion of ice on Antarctica3,4induced crustal deformation and gravitational perturbations around the continent. Close to the ice sheet, sea level rose5,6despite an overall reduction in the mass of the ocean caused by the transfer of water to the ice sheet. Here we identify the crustal response to ice-sheet growth by forcing a glacial-hydro isostatic adjustment model7 with an Antarctic ice-sheet model. We find that the shelf areas around East Antarctica first shoaled as upper mantle material upwelled and a peripheral forebulge developed. The inner shelf subsequently subsided as lithosphere flexure extended outwards from the ice-sheet margins. Consequently the coasts experienced a progressive relative sea-level rise. Our analysis of sediment cores from the vicinity of the Antarctic ice sheet are in agreement with the spatial patterns of relative sea-level change indicated by our simulations. Our results are consistent with the suggestion8 that near-field processes such as local sea-level change influence the equilibrium state obtained by an icesheet grounding line
