Portfolio management can also be defined as the aggregation and management of a diverse portfolio of supply ( and demand-reduction ) resources which will act as a hedge against various risks that may affect specific resources ( i.e ., fuel price fluctuations and certainty of supply , common mode failures , operational reliability , changes in environmental regulations , and the risk of health , safety , and environmental damages that may occur as a result of operating some supply resources ) . Students selecting the course work plan are required to present to their Graduate Committee a portfolio of completed projects that demonstrate competencies in specific areas ( i.e ., instructional design , multimedia development , graphics applications , etc. ) . Statistics about specific subsets ( e.g ., number of photos of Namibia ) can be compiled from the Technical Search page . Specific conditions ( e.g ., type of contaminant , amount of contamination , levels of protection required , type of protective clothing worn ) are then evaluated , and the initial decontamination plan is modified to adapt as new information about site conditions becomes available . Environmental sensitivities include asthma and adverse reactions to specific allergens ( e.g ., perfumes ) , including building construction materials ( e.g ., " building-related illness " or " sick building syndrome " ) .
