Evaluation Frameworks for Egovernment Services

The present work introduces an evaluation framework for small-dimension solar cookers based on three parameters: energy efficiency, ease of use, and economic accessibility. Each parameter evaluates various quantifiable indicators, as a) energy efficiency: standardized cooking power, heating time, and thermal performance, b) ease of use: load capacity in the pot, mass in relation to collector area, orientations per hour, and c) economic accessibility: cost per watt generated and durability of the reflector and/or thermal accumulator. Each indicator has been assigned a maximum and minimum evaluation; data obtained from these indicators were integrated in a radial graph. The sum of the indicators constitutes the aspect to be compared, but the graph also allows us to interpret the strengths and weaknesses described above. This framework requires two or more devices, since it is a comparative tool. RESUMEN Este documento presenta un marco de evaluación para las cocinas solares con base en tres parámetros: eficiencia energética, facilidad de uso y accesibilidad económica. Cada paráme-tro evalúa diversos indicadores cuantificables: a) eficiencia energética: potencia de cocción estándar, tiempo de calentamiento, el rendimiento térmico; b) facilidad de uso: la masa en relación al área del colector, orientaciones por hora y capacidad de carga de la olla y; c) accesibilidad económica: el coste por vatio generado y la durabilidad del reflector y/o acu-mulador térmico. A cada indicador se le asigna una escala máxima y mínima de la evalua-ción y los datos obtenidos de estos indicadores se integran en un gráfico radial. La suma de los indicadores constituye el aspecto que debe compararse, pero el gráfico también nos permite interpretar las fortalezas y debilidades descritas. Este marco no se puede analizar una sola cocina solar, ya que es una herramienta comparativa que requiere dos o más dispositivos que deseen evaluarse.

Some of the most challenging e-government applications involve allowing citizens and other customers such as businesses to conduct financially related transactions electronically with governments on a 24-hour, 7-day a week basis. There has been little empirical research on the utilization rates of on-line financial applications. This paper reviews existing data concerning usage rates and presents new data from governments at

The benefits of e-government to U.S. residents and government agencies includes timely access to information and convenient ways to execute government transactions as described for the Presence, Interaction and Transaction stages. However, the most anticipated stage of Transformation, which aims to improve public engagement through interactive and bidirectional exchanges between residents and the government, is still not commonly featured in municipal, state, and federal websites.

—Recently the Greek Government has devoted significant effort to streamlining business processes using ICT to better manage public administration resources. To this end, public sector services are designed so that they are accessed through single points, while increasing transparency and reducing cycle time for executing processes and disseminating information to civil and other agencies. To control the services provided by state agencies and to improve them continuously, it seems essential that they are continuously evaluated by users. This paper focuses on the field of e-government and more precisely describes an evaluation method for investigating the success of an e-government project. Specifically, a technology adoption model is proposed, which focuses on the specific characteristics of users for the on-line services of an Independent Authority. The model is essentially based on the framework of the Unified Theory of Acceptance and the Use of Technology (UTAUT2) model, which has been enhanced with four additional criteria.
