Objective: This study aimed to evaluate the effect of closed-loop management on nursing disruption risk. Methods: Using a quasi-experimental research method, convenient sampling was used to extract 20 nurses working at our hospital as the research objects. The control group members were selected from January to March 2018 via the traditional method, and the experimental group members were selected from April to June 2018 via the closed-loop management method. At three months before and after the implementation of the management model, a self-designed quantitative test form and satisfaction questionnaire were used to analyze the frequency of nursing disruption events, the accuracy rate of doctors' advice, the average drug delivery time of the static distribution center, the implementation rate of personal digital assistant (PDA) code scanning, and the report rate of risk-outcome nursing disruption events. Results: After the implementation of the management model, the frequency of nursing disruptions and average drug delivery time of the static distribution center were significantly lower than before, and the differences were statistically significant (p < 0.05). Moreover, the accuracy rate of doctors' advice, the implementation rate of PDA code scanning, and the reporting rate of risk-outcome nursing disruption events were significantly higher than before, and these differences were statistically significant as well (p < 0.05). Conclusion: The application of a closed-loop management model could significantly reduce the occurrence and optimize the outcomes of nursing disruption events and improve the work processes of medical care.

PurposeBased on the theoretical predictions of media equation theory and the computers-are-social-actors (CASA) perspective, this study aims to examine the effects of performance error type (i.e. logical, semantic or syntactic), task type and personality presentation (i.e. dominant/submissive and/or friendly/unfriendly) on users’ level of trust in their personal digital assistant (PDA), Siri.Design/methodology/approachAn experimental study of human–PDA interactions was performed with two types of tasks (social vs functional) randomly assigned to participants (N = 163). While interacting with Siri in 15 task inquiries, the participants recorded Siri’s answers for each inquiry and self-rated their trust in the PDA. The answers were coded and rated by the researchers for personality presentation and error type.FindingsLogical errors were the most detrimental to user trust. Users’ trust of Siri was significantly higher after functional tasks compared to social tasks when the effects of general usage (e.g. proficiency, length and frequency of usage) were controlled for. The perception of a friendly personality from Siri had an opposite effect on social and functional tasks in the perceived reliability dimension of trust and increased intensity of the presented personality reduced perceived reliability in functional tasks.Originality/valueThe research findings contradict predictions from media equation theory and the CASA perspective while contributing to a theoretical refinement of machine errors and their impact on user trust.

As new technological innovations are rapidly introduced and changed, identifying an individual characteristic that has a persistent effect on the acceptance decisions across multiple technologies is of substantial value for the successful implementation of information systems. Augmenting prior work on individual innovativeness within the context of information technology, we developed a new measure of adopter category innovativeness (ACI) and compared its effectiveness with the existing measure of personal innovativeness in IT (PIIT). Further, we examined two alternative models in which the role of individual innovativeness was theorized differently—either as a moderator of the effects the perceived innovation characteristics of usefulness, ease of use, and compatibility have on future use intention (moderator model) or as a direct determinant of the innovation characteristics (direct determinant model). To ensure the generalizability of the study findings, two field studies (N= 634) were conducted, each of which examined the two models (moderator and direct determinant) and measured individual innovativeness using the two measures (ACI and PIIT). Study 1 surveyed the online buying practices of 412 individuals, and Study 2 surveyed personal digital assistant adoption of 222 healthcare professionals. Across the markedly different adoption contexts, the study results consistently show that individual innovativeness is a direct determinant of the innovation characteristics, and the two measures share many commonalities. The new measure offers some additional utilities not found in the PIIT measure by allowing individuals to be directly classified and mapped into adopter categories. Implications are drawn for future research and practice.

Health care personnel need access to updated information anywhere and at any time, and a Personal Digital Assistant (PDA) has the potential to meet these requirements. A PDA is a mobile tool which has been employed widely for various purposes in health care practice, and the level of its use is expected to increase. Loaded with suitable functions and software applications, a PDA might qualify as the tool that personnel and students in health care need. In Sweden today, despite its leadership role in mobile technologies, PDAs are not commonly used, and there is a lack of suitable functions and software applications. The aim of the present review was to obtain an overview of existing research on the use of PDAs among personnel and students in health care. The literature search included original peer-reviewed research articles written in English and published from 1996 to 2008. All study designs were considered for inclusion. We excluded reviews and studies focusing on the use of PDAs in classroom situations. From March 2006 to the last update in May 2008, we searched PubMed, CINAHL, Cochrane, IngentaConnect, and a local search engine (ELIN@Kalmar). We conducted a content analysis, using Nielsen's Model of System Acceptability as a theoretical framework in structuring and presenting the results. From the 900 references initially screened, 172 articles were selected and critically assessed until 48 articles remained. The majority originated in North-America (USA: n=24, Canada: n=11). The categories which emerged from our content analysis coincided to a certain extent to Nielsen's Model of System Acceptability (social and practical acceptability), including usefulness (utility and usability) subcategories such as learnability, efficiency, errors, and satisfaction. The studies showed that health care personnel and students used PDAs in patient care with varied frequency. Most of the users were physicians. There is some evidence that the use of a PDA in health care settings might improve decision-making, reduce the numbers of medical errors, and enhance learning for both students and professionals, but the evidence is not strong, with most studies being descriptive, and only 6 randomized controlled trials. Several special software programs have been created and tested for PDAs, and a wide range of situations for their use have been reported for different patient groups. Drug and medical information were commonly accessed by PDA users, and the PDA was often viewed as the preferred tool when compared to paper-based documents. Some users regarded the PDA easy to operate, while others found it difficult in the beginning. This overview of the use of PDAs revealed a positive attitude towards the PDA, which was regarded as a feasible and convenient tool. The possibility of immediate access to medical information has the potential to improve patient care. The PDA seems to be a valuable tool for personnel and students in health care, but there is a need for further intervention studies, randomized controlled trials, action research, and studies with various health care groups in order to identify its appropriate functions and software applications.

The purpose of this study was to evaluate the use of a Personal Digital Assistant with multiple prompt levels to increase completion of novel task boxes and transitioning within and between tasks. The study used a multiple probe design across three sets of task boxes replicated with three students with a diagnosis of autism spectrum disorder. Results indicated that: task completion was higher for two of the students compared to baseline conditions using a picture-based task strip; all students were able to complete a greater number of between task transitions using the PDA; students performed within task transitions equally as well using the PDA and the task strip; and one student began to self-fade use of more intrusive prompt levels.

Personal digital assistants (PDAs) find many uses in health care. Knowing rates of collective PDA use among health care providers is an important guiding step to further understanding those health care contexts that are most suited to PDA use and whether PDAs provide improved health outcomes. The objectives of this study were to estimate current and future PDA use among health care providers and to discuss possible implications of that use on choice of technology in clinical practice and research. This study was a systematic review of PDA usage surveys. Surveys were identified as part of an ongoing systematic review on the use of handheld devices. Reports from eight databases covering both biomedical sciences and engineering (1993-2006) were screened against distinct eligibility criteria. Data from included surveys were extracted and verified in a standardized way and were assessed descriptively. We identified 23 relevant surveys, 15 of which were derived from peer-reviewed journals. This cohort of surveys was published between 2000 and 2005. Overall, since 1999, there is clear evidence of an increasing trend in PDA use. The current overall adoption rate for individual professional use ranges between 45% and 85%, indicating high but somewhat variable adoption, primarily among physicians. Younger physicians and residents and those working in large and hospital-based practices are more likely to use a PDA. The adoption rate is now at its highest rate of increase according to a commonly accepted diffusion of innovations model. A common problem with the evaluation of information technology is that use frequently precedes research. This is the case here, in which PDA adoption rates are already high and projections are for rapid growth in the short term. In general, it appears that professional PDA use in health care settings involves more administrative and organizational tasks than those related to patient care, perhaps signaling where the growth in adoption is most likely to occur. We conclude that physicians are likely accustomed to using a PDA, and, therefore, technology expertise will probably not be a barrier to implementing PDA applications. However, there is an urgent need to evaluate the effectiveness and efficiency of specific tasks using handheld technology to inform those developing and those using PDA applications.

PurposeWith the continuous improvement of artificial intelligence (AI) technology, intelligent personal assistants (IPAs) based on AI have seen unprecedented growth. The present study investigates the effect of anthropomorphism on cognitive and emotional trust and the role of interpersonal attraction in the relationship between anthropomorphism and trust.Design/methodology/approachA structural equation modeling technique with a sample of 263 consumers was used to analyze the data and test the conceptual model.FindingsThe findings illustrate that the anthropomorphism of IPAs did not directly induce trust. Anthropomorphism led users to assign greater social attraction and task attraction to IPAs, which in turn reinforced cognitive or emotional trust in these assistants. Compared with task attraction, social attraction was more powerful in strengthening both cognitive trust and emotional trust. The present study broadens the current knowledge about interpersonal attraction and its role in AI usage by examining two types of interpersonal attraction of IPAs.Originality/valueAs trust plays an important role in the rapid development of human–computer interaction, it is imperative to understand how consumers perceive these intelligent agents and build or improve trust. Prior studies focused on the impact of anthropomorphism on overall trust in AI, and its underlying mechanism was underexplored. The findings can help marketers and designers better understand how to enhance users' trust in their anthropomorphic products, especially by increasing social interactive elements or promoting communication.

Ubiquitous computing and mobile technologies provide a new perspective for designing innovative outdoor learning experiences. The purpose of this study is to propose a formative assessment design for integrating PDAs into ecology observations. Three learning activities were conducted in this study. An action research approach was applied to continually revise the worksheet designs. Twenty-seven 5^(th) and 6^(th) graders' observation skills using PDAs, and their extended inquiry performance using e-diaries were assessed. An e-library, and online scoring and feedback systems were developed accordingly. The results suggest that the embedded formative assessment designs were effective for guiding and supporting the students' learning progress. The activity worksheets successfully helped the students focus their outdoor learning attention on the target tasks. The e-library provided reliable resources to clarify their observed descriptions, while the automatic scoring and feedback systems were especially helpful in sustaining the students' persistent effort. Most students demonstrated substantial improvements in their observation skills, and extended their inquiry abilities. The well designed online formative assessment embedded in the activity worksheet is very promising for PDA integrated learning.

Purpose The purpose of this paper is to identify factors influencing the adoption of mobile banking in India and develop and empirically validate a model explaining the behavioural intention to use mobile banking in the Indian banking sector. Design/methodology/approach In this study, a model is developed and proposed to explain customers’ intention to use mobile banking. The model comprises six constructs, namely, perceived ease of use, computer self-efficacy, social influence, perceived financial cost, security, and trust. The model also describes the relationship between perceived ease of use and computer self-efficacy, as well as that between security and trust. The proposed model was tested by using a survey method, with a sample of 855 bank customers from public, private, foreign, and cooperative banks in India. Structural equation modelling analysis was performed with AMOS 16.0. Findings The proposed theoretical model was found to predict, with statistical significance, the intention to use mobile banking, explaining 76.9 per cent of the variance in the dependent variable. The results found that security, computer self-efficacy, perceived ease of use, and perceived financial cost, in that order of influence, affect customers’ intention to adopt mobile banking. Practical implications The results obtained will help both academic researchers and practitioners explain, understand, and elucidate the status of mobile banking in India, as well as helping them formulate strategies to expedite the use of mobile banking. Originality/value The adoption of mobile banking in India is in a nascent stage compared with developed countries such as the USA, the UK, and Finland, but it is expected to increase or surpass the rate of adoption of internet banking in those countries. Further, only limited research to date has examined the adoption of mobile banking in India, especially the drivers and inhibitors of mobile banking adoption.

Purpose – The purpose of this paper is to provide useful insights on “bring your own device” (BYOD) and IT consumerization, to help organizations understand how to address their consequences. For young, tech-savvy workers, using their own devices at work represents a right, rather than a privilege, leading them to initiate a growing, yet under-researched, drive toward IT consumerization. Some companies already deploy BYOD programs, allowing employees to use personal devices for work-related activities, but other managers remain hesitant of the implications of such programs. Design/methodology/approach – To provide an overview of this growing phenomenon, this paper presents an in-depth analysis of existing literature and identifies organizational changes induced by this reversed adoption logic. A case study of Volvo reveals how one organization has coped successfully with this phenomenon. Findings – These analyses shed more light on the stakes involved in BYOD and IT consumerization, as well as the changes they imply for organizations and IT departments. Practical implications – Both BYOD and IT consumerization have deep and broad consequences for organizations, some of which are very positive, as long as the trends are well-managed and carefully addressed. Originality/value – This paper covers a topic that has attracted scant attention in prior academic research, despite widely acknowledged concerns about security and reliability in practitioner studies. By going beyond a classic discourse focused solely on the security threats of BYOD, this paper investigates both business challenges and implications associated with a reversed adoption logic.
