RESUMO
The reconstruction of pollution in aquatic ecosystems is a useful tool to evaluate the effectiveness of management actions. Cartagena Bay (Colombia, Caribbean Sea) is one of the most impacted coastal zones in Colombia by a wide variety of human activities. A sediment core was dated using 210Pb and used to reconstruct the historical input of heavy metals, polycyclic aromatic hydrocarbons (PAHs), and organochlorinated pesticides to the bay. The highest pollutant concentrations were observed in the deeper core layers. The maximum mercury concentration (18.76 µg g-1) was observed at 61 cm depth, corresponding to 1967, when a chlor-alkali plant was operating. Since all pollutant concentrations have decreased due to better industrial management policies, their presence is a potential contamination risk through sediment remobilization and pollutant resuspension.

Ecosystem services are only able to make a contribution to human well-being if they reach the users or beneficiaries. Therefore, it is important to differentiate the potential contributions of ecosystems (ecosystem service supply) from the fraction of the supply that is captured or used. This is even more relevant when the supply and capture of the service occur in different locations. In this case, propagation models are needed to identify who wins and who loses when land-use policies are applied. In this study, we developed an integrated approach for the analysis of supply, propagation and capture patterns of flood-mitigation ecosystem service in rural landscapes and we illustrated how to apply it for the identification of winning and losing farmers under alternative land-use scenarios. The proposed approach allowed us to differentiate farms according to their flood mitigation capacity and to estimate how that capacity could be affected by changes in land use. It also highlights the importance of considering the propagation and capture of ecosystem services in evaluations. Reliable methodological developments are scarce. Therefore, flexible tools such as this proposal are necessary to fit the available information and the context to be analyzed.

Objetivo: Determinar el desempeño profesional de los egresados del programa de enfermería que laboran en instituciones hospitalarias. Materiales y métodos: Se realizo estudio cuantitativo descriptivo de corte transversal. Con una muestra de 120 profesionales de enfermería pertenecientes a cuatro (4) Instituciones Hospitalarias del municipio de Cúcuta que cumplieron los criterios de inclusión. Para la recolección de la información se aplico instrumento compuesto por datos de identificación, perfil profesional, condiciones generales de trabajo y desempeño laboral. Resultados: el 85% de los egresados de manera satisfactoria realizan acciones gerenciales, administrativas y del cuidado, y solo el 50% de estos desarrolla actividades de educación e investigación. Conclusión: Los egresados del programa de enfermería de la Universidad Francisco de Paula Santander consideran que los contenidos aprendidos durante su carrera son excelentes y buenos, y les ha permitido en la práctica profesional desempeñar diversidad de cargos y acciones.
Job performance of nurses (a) graduates of the University Francisco de Paula Santander Abstract Objective: To determine the professional performance of the Nursing Program graduates who work in hospitals. Materials and methods: descriptive quantitative study of cross section. With a sample of 120 nurses from four (4) hospitals in Cucuta city who met the inclusion criteria. For data collection instrument was applied comprising identification data, professional profile, working conditions and job performance. Results: 85% of graduates successfully perform management actions, administrative and care, and only 50% of these develops educational and research activities. Conclusion: the graduates of the Nursing Program at the Francisco de Paula Santander University consider the contents learned during his career are excellent or good, and allowed them to play in professional practice diversity of positions and actions.
