Stakeholder´s analysis in e-learning software process development

The success of an e-learning project depends largely on the quality of applications and tools used to support the learning process. Meanwhile, the quality of software depends largely on proper stakeholders? identification in the requirements stage during the development process. Although some studies exist which have identified key stakeholders in e-learning domain, most of them do not perform a deep analysis of the stakeholders and their contexts, necessary to consider educational and cultural issues in this type of environment. The aim of this paper is to present the application of a method for the identification and analysis of stakeholders, which is adapted to e-learning domain. This method was used in a case study considering university environments.Fil: Romero, Lucila J.. Universidad Nacional del Litoral.

Parent and Household Influences on Calcium Intake Among Early Adolescents

Background: Calcium intake during early adolescence falls short of requirements for maximum bone accretion. Parents and the home food environment potentially influence children’s calcium intakes. This study aimed to quantify parental psychosocial factors (PSF) predicting calcium intakes of Asian, Hispanic, and non-Hispanic white (NHW) early adolescent children from a parental perspective. Methods: This was a cross-sectional study involving the administration of a validated calcium-specific food frequency questionnaire to a convenience sample of children aged 10–13 years and the primary individual responsible for food acquisition in the child’s household. Based on Social Cognitive Theory, parental factors potentially associated with children’s calcium intake were also assessed via parent questionnaires. The total study sample consisted of 633 parent-child pairs (Asian = 110, Hispanic = 239, NHW = 284). Questionnaires were completed at community-based centers/sites. Outcome measures were the association between parent-child calcium (mg), milk (cups/day), and soda (cans/day) intakes and the predictive value of significant parental PSF towards calcium intakes of their children. Sex-adjusted linear regression and multivariate analyses were performed. Results: Calcium intakes of parent-child pairs were positively associated among all ethnic groups (r = 0.296; P \u3c 0.001). Soda intakes were positively associated among Hispanic parent-child pairs only (r = 0.343; P \u3c 0.001). Home availability of calcium-rich foods (CRF), parental rules and expectations for their child’s intake of beverages, and parents’ calcium intake/role modeling were positively associated with children’s calcium intake and overwhelmed all other PSF in multivariate analyses. Significant cultural differences were observed. Parental role modeling was a significant factor among Hispanic dyads only. Multivariate models explained 19–21% of the variance in children’s calcium intakes. Conclusions: Nutrition interventions to improve children’s calcium intakes should focus on parents and provide guidance on improving home availability of CRF and increasing rules and expectations for the consumption of CRF. Among Hispanic families, interventions promoting parental modeling of desired dietary behaviors may be most successful

Dietary Sources of Calcium Among Parents and Their Early Adolescent Children in the United States by Parent Race/Ethnicity and Place of Birth

Dietary calcium sources may differ by race/ethnicity and dietary acculturation. A cross-sectional, convenience sample including 587 United States (US) Asian, Hispanic and non-Hispanic White parent–child (10–13 years) pairs completed a calcium food frequency questionnaire. Calcium sources were ranked by mean percent contribution to total adjusted calcium intake, and compared by ethnic group and parents’ location of birth. Five foods (fluid milk, cheese, milk on cereal, yogurt, and lattes) represented 49 % of total calcium intake for parents. The same foods (except lattes) represented 55 % of total calcium for early adolescent children. Fluid milk provided the largest mean percentage of intake for all race/ethnic groups among parents and children. Several food sources of calcium were greater for foreign-born versus US-born Asian or Hispanic parents and children. Understanding calcium food sources and changes in dietary patterns that affect calcium intake among parents and children is important to better promote adequate intake
