Objective: This literature review is to detect the gab in the body of knowledge regarding issues of incidents reporting practices, leadership behaviors, and organizational culture especially in Jordanian context, as well as, to give reflection about the searched studies and to address the strength and weakness points of each study as well. The design of the current article was literature review of twenty five studies. Results: The current review revealed that most of the research studies were conducted in order to explore the perceptions of healthcare providers about patient safety issues, and clinical incidents reporting practices as well, however, there are few studies that were conducted in order to investigate the influence of leadership behaviors and organizational culture on incidents reporting practices as perceived by Jordanian hospitals’ registered nurses. Moreover, it seems that in Jordanian context, it is not fully understood the influence of leadership behaviors and organizational culture on incidents reporting practices as perceived by Jordanian hospitals’ registered nurses. Conclusion: It is imperative for researchers to fill the gap that existed in the body of knowledge regarding the variables of leadership behaviors, hospitals’ organizational culture and incidents reporting practices in order to enhance patient safety and safety practices in health care organizations. Relevance to clinical practice: Exploring the influence of leadership behaviors and organizational culture on incidents reporting practices among registered nurses in Jordan is highly recommended. Finally, the current review identifies the gap in the body of knowledge regarding the mentioned above variables.展开更多

Based on analyzing function of CNC software, the article presents how to construct a general class library of CNC software with OO technology. Most function modules of CNC software can he reused because of inheritable capability of classes. Besides, the article analyzes the object relational model in request/report mode, and multitask concurrent management model, which can he applied on double-CPU hardware platform and Windows 95/NT environment. Finally, the method has been successfully applied on a turning CNC system and a milling CNC system, and some function modules have been reused.展开更多

The nature of mobile environments differs from that of PC and server environments due to many factors, such as the network, energy, battery, and compatibility. Evaluating and predicting mobile application reliability are real challenges because of the diversity of the mobile environments in which the applications are used, and the lack of publicly available defect data. In addition, bug reports are optionally submitted by end-users. In this paper, we propose assessing and predicting the reliability of a mobile application using known software reliability growth models (SRGMs). Four software reliability models are used to evaluate the reliability of an open-source mobile application through analyzing bug reports. Our experiment proves it is possible to use SRGMs with defect data acquired from bug reports to assess and predict the software reliability in mobile applications. The results of our work enable software developers and testers to assess and predict the reliability of mobile software applications.</span> </div>展开更多

A bug localization model based on syntactical and semantic information of source code is proposed. Firstly, abstract syntax tree(AST) is divided based on node category to obtain statement sequence. The statement tree is encoded into vectors to capture lexical and syntactical knowledge at the statement level.Secondly, the source code is transformed into vector representation by the sequence naturalness of the statement. Therefore,the problem of gradient vanishing and explosion caused by a large AST size is obviated when using AST to the represent source code. Finally, the correlation between bug reports and source files are comprehensively analyzed from three aspects of syntax, semantics and text to locate the buggy code. Experiments show that compared with other standard models, the proposed model improves the performance of bug localization, and it has good advantages in mean reciprocal rank(MRR), mean average precision(MAP) and Top N Rank.展开更多
