The Descartes Query Language (DQL) enables to query the performance of a system using adapters to various solution approaches. Thereby, DQL is a realization of the vision of Declarative Performance Engineering (DPE) which decouples the description of user concerns (performance questions and goals) from the task of selecting and applying a specific solution approach. While model-based approaches...

This paper addresses challenges involved with measuring the performance of an Enterprise Java Bean (EJB) based system in a production environment. These challenges include specific requirements for the measuring system to be non-intrusive, have low-overhead, and to be able to provide monitoring and visibility to all the business objects in the production system. A prototype EJB Performance Meas...

This paper investigates the e ect of performance measurement on the optimal e ort allocation by salespeople when rms are concerned about retention of salespeople with higher abilities. It shows that introducing salespeople performance measurement may result in productivity, pro t, and welfare losses when all market participants optimally respond to the expected information provided by the measu...

Formative measurement models were first introduced in the literature more than forty years ago and the discussion about their methodological contribution has been increasing since the 1990s. However, the use of formative indicators for construct measurement in empirical studies is still scarce. This paper seeks to encourage the thoughtful application of formative models by (a) highlighting the ...

Information plays a central role in the ability of a health system to deliver effective health care and secure population health. It is used for a variety of different purposes in health care: to secure accountability within the system, to determine appropriate treatments for patients, to facilitate patient choice and/or for managerial control. Information also plays an important broader role i...

Model Driven Engineering is an emerging approach in software development which argues using models as primary software artifacts. The models can vary from prescriptive ones specified in Domain Specific Modeling Languages (DSMLs), for the domain specific software development (e.g. Graphical User Interfaces DSML), to descriptive models for analysis, such as queuing networks and Petri-nets. The ma...

The authors review research on judgments of random and nonrandom sequences involving binary events with a focus on studies documenting gambler's fallacy and hot hand beliefs. The domains of judgment include random devices, births, lotteries, sports performances, stock prices, and others. After discussing existing theories of sequence judgments, the authors conclude that in many everyday setting...

Lecturers are one of the main components in development higher education, especially at private universities South Sulawesi. To improve lecturer performance, it is necessary to increase performance personal competence. This research examines depth measurement models tertiary institutions. For design needs model, determine indicators and priority scale weighting Key Performance Indicators (KPIs)...

altered customer demands create a new dynamic and ibility and mobility of enterprises (Camarinha-Matos, 2002). For these reasons, different enterprises have to cooperate in order to meet customer needs effectively, to encounter the contemporary prevalent high competition and innovation pressure as well as to be permanently successful in largely saturated markets. In this respect, the opening of...
