In this paper we consider the way in which two representational forms, scenarios and design breakdowns, which have emerged in the tradition of participatory design are relevant within the recent commercial emphasis on rapid application development (RAD). RAD is a contingent approach to interactive software development that is characterised by large amounts of user involvement, incremental proto...

BACKGROUND There is increasing recognition that patients have critical insights into care experiences, including breakdowns in care. Harnessing patient perspectives for hospital improvement requires an in-depth understanding of the types of breakdowns patients identify and the impact of these events. METHODS We interviewed a broad sample of patients during hospitalization and postdischarge to...

Number of breakdowns experienced by a machinery is a highly under-dispersed count random variable and its value can be attributed to the factors related to the mechanical input and output of that machinery. Analyzing such under-dispersed count observations as a function of the explanatory factors has been a challenging problem. In this paper, we aim at estimating the effects of various factors ...

Background: Failure to establish and maintain close romantic relationships with commitment can hinder an individual’s development and have adverse effects on his/her well-being in life due to the potential emergence of serious problems. The present study aimed to investigate the relative effectiveness of acceptance and commitment therapy (ACT) and schema therapy on love trauma syndrome and self...

a two server queueing system with single and batch service is considered in this paper. the arrival process is assumed to be poisson and the service rate follows an exponential distribution. server-i serves the customers in both single and batch service, while server-ii serves the customers in batch service only. the laplace transform of the transient and steady state behavior of the model is c...

in this paper, we present a novel algorithm for vanet using cloud computing. we accomplish processing, routing and traffic control in a centralized and parallel way by adding one or more server to the network. each car or node is considered a client, in such a manner that routing, traffic control, getting information from client and data processing and storing are performed by one or more serve...

This paper focuses on a stochastic scheduling problem in which n immediately available jobs are to be scheduled jointly with the preventive maintenance in a single machine subject to breakdowns. The objective is to minimize expected total earliness and tardiness costs with a common due-date. The problem of scheduling only n jobs to minimize total earliness and tardiness costs in a single machin...

The paper reports an empirical study of the use of videoconferences in decentralized university education. The study focuses on breakdowns that occur during the transition of educational practices from regular classrooms to videoconference-based environments. It was found that the breakdowns were mainly caused by physical and organizational distribution of decentralized education. The paper con...

Timely and accurate communication is essential to safe and effective health care. Despite increased awareness over the past decade of the frequency of medical errors and greater efforts directed towards improving patient safety, patient harm due to communication breakdowns remains a significant problem. Communication problems related to diagnostic testing may account for nearly half of all erro...
