As the use, develophient, and control of information systems continues to become diffused throughout organizations and society, the information technology (IT) help desk function plays an increasingly important role in effective management and utilization of information resources. Variously referred to as information centers, software support centers, software hotlines, and PC help desks, such ...

We present the implementation of Distributed Constructionism (DC) through a Participatory Design (PD) methodology for an Online Learning community. The students collaborate on the content and functionality development of an online Modern Greek language course, peer review and publish content contributions, and participate in participatory design teams. Participatory design was implemented as a ...

Semiformale Modellierungssprachen zur Beschreibung technischer, organisatorischer oder betriebswirtschaftlicher Zusammenhänge haben eine zentrale Bedeutung für das Anforderungsmanagement (Requirements Engineering). Die Modifikation bestehender und die Entwicklung neuer semiformaler Modellierungssprachen nehmen trotz der vorhandenen Vielfalt weiter zu. Der Schwerpunkt von Forschungsarbeiten zur ...

This paper makes an important methodological contribution regarding the use of free questionnaires, illustrated through a study that shows that a healthcare professional’s propensity to use electronic communication technologies creates opportunities for interaction with other professionals, which would not otherwise be possible only via face-to-face interaction. This in turn appears to increase...

The last decade has seen the proliferation of business-to-employee (B2E) portals as integrated, efficient, and user-friendly technology platform to assist employees to increase their productivity, as well as for organizations to reduce their operating costs. To date, very few studies have focused on determining the extent to which the portal implementations have been successful. Such a study is...

Electrical activity in nerve, skeletal muscle, and heart requires finely tuned activity of voltage-gated Na channels that open and then enter a nonconducting inactivated state upon depolarization. Inactivation occurs when the gate, the cytoplasmic loop linking domains III and IV of the subunit, occludes the open pore. Subtle destabilization of inactivation by mutation is causally associated wit...

We use task-technology-fit model to develop an instrument for obtaining user evaluations of IT in health care. Our results indicate that task-technology fit along with individual characteristics have an impact on user evaluation of the IT in health care. We modify the original task-technology fit model for adequate domain coverage in health care industry. The contribution of our study is toward...

System analysts are service providers who are required to work closely with users for the purpose of defining, developing and implementing computer-based systems. Analysts and users in pdvate organizations may have different expectations and proficiencies than those in public organizations, in part due to the types of appli. cations required. Beliefs about how others are supposed to perform and...

Software developers’ performance has a direct impact on software development productivity. An understanding of the factors that affect this performance could help determine where to concentrate management efforts (and related financial resources) from a practical standpoint, and where to focus research efforts from an academic perspective. To gain further insight into these factors, this study ...
