This work experimentally demonstrates that the imaging quality of quantum ghost imaging (GI) with entangled photons can be significantly improved by properly handling the errors caused by the imperfection of optical devices. We also consider compressive GI to reduce the number of measurements and thereby the data acquisition time. The image reconstruction is formulated as a sparse total least square problem which is solved with an iterative algorithm. Our experiments show that, compared with existing methods, the new method can achieve a significant performance gain in terms of mean square error and peak signal–noise ratio.

Abstract Background Nurses have a vital role in the healthcare system. One of the basic steps to increase their happiness is to recognize factors such as job satisfaction and quality of working life. Therefore, the goal of the present study was to examine the relationship between happiness and quality of working life and job satisfaction among nursing personnel. Methods This descriptive study was carried out on 270 hospital nurses who worked in emergency departments in Iran. Nurses were recruited through the census method. Data collection instruments included the Oxford Happiness Inventory (OHI), the Quality of Work Life Questionnaire (QWL), and the Job Satisfaction Questionnaire (JSQ). Data were explored using descriptive statistics, and stepwise multiple linear regression analysis. Results The mean age of participants was 30.1 ± 6.26 years. The mean happiness score was 38.5 ± 16.22, the mean Quality of Working Life (QWL) score was 84.3 ± 17.62, and the mean job satisfaction score was found to be 45.5 ± 13.57); corresponding to moderate levels of attributes. The results obtained from the ordinary least-square (OLS) regression indicated that happiness significantly was associated with economic status and satisfaction with closure (R2: 0.38). Conclusion Overall the current study found that nurses who work in emergency departments did not feel happy. Additionally, the findings suggest that their happiness were associated with their economic status, and closure over their duties.

Objectives: The objective of this study was to examine the formation of wellness perceptions and satisfaction from antecedents that explain various attributes regarding service quality perceptions about doctors by patients. The topic is of contemporary relevance as health-care firms are reengineering their competencies to deliver personalized health services to for unmatched experience to develop long-term relationships with patients.Methods: Responses from 280 patients about service quality attributes of doctors, wellness perceptions, and their satisfaction are collected using a structured questionnaire. An exploratory factor analysis was performed using SPSS. 20 to identify significant dimensions of doctor’s service quality. The theoretical model developed with these dimensions, wellness perceptions, and patient satisfaction was estimated using partial least square-based structural equation modeling approach to test hypotheses about linkages among these constructs.Results: The dimension structure of doctor’s service quality contained constructs such as “price affordability of medicines,” “quality of diagnosis,” “interaction quality of doctor,” “appropriateness of tests prescribed,” and “quality of usage prescriptions.” These service quality dimensions of doctor significantly develop wellness perceptions and satisfaction among patients. Wellness perceptions act as a mediator in satisfaction development.Conclusions: Patient satisfaction and wellness perceptions are of primary importance in improving service quality in health care and to remain competitive. The health-care firms should train their professionals to interact with the patients more efficiently by adhering to the philosophy of patient centeredness in their service process.

Flexible Framework

As wireless sensor networks (WSNs) often provide incorrect and outdated information about the events in a monitored environment, quality of information (QoI) assessment is invaluable for users to manage and use the information in particular applications. In this paper, we propose a flexible framework to dynamically assess the QoI in different WSN applications, with focus on accuracy and timeliness. Our framework is constructed on the infrastructure of an information aggregation procedure under some assumptions about the network. Based on information fusion theory, two processing models are adopted to assess the accuracy of low-level measurement data and high-level decision information without the need for Ground Truth (GT). Meanwhile, our framework generally exploits two respective models according to the specific category of the information timeliness in different delay-sensitive applications. To quantify the timeliness, we utilize a practical measurement method by means of timestamp to determine the information acquisition time. The framework is evaluated by simulations, including accuracy assessment in two environmental monitoring application scenarios, and timeliness assessment in two delay-sensitive application scenarios. The simulation results show that our framework is effective and flexible for quantitative assessment of the QoI in different WSN applications.
