    This study aims to investigate the innovation of Online Banking Transaction (OBT) risk communication issues inside banks in Jordan from the socioorganisational point-of-view through studying the effects of national and organisational cultures on the risk communication process. Although risk communication issue has been approved to be one of the success reasons of Online Banking (OB) usage, the risk communication approaches that have been developed during past years tend to offer narrow technically oriented solutions, and they have not paid enough attention to the social aspects of risks and the informal structures of organizations. Using the previous research findings, this study presents a socioorganisational approach to the OBT risk communication innovation process inside banks in Jordan, which enrich the in depth understanding for practical projects and empirical research contexts

    Deep neural network models have become powerful tools of machine learning and artificial intelligence. They can approximate functions and dynamics by learning from examples. This paper reviews the state-of-art of deep learning-based object detection frameworks that are used for fruit detection in general and for olive fruit in particular. A dataset of olive fruit on the tree is built to train and evaluate deep models. The ultimate goal of this work is the capability of on-edge real-time olive fruit detection on the tree from digital videos. Recent work in deep neural networks has led to the development of a state-of-the-art object detector termed You Only Look Once version five (YOLOv5). This paper builds a dataset of 1.2 K source images of olive fruit on the tree and evaluates the latest object detection algorithms focusing on variants of YOLOv5 and YOLOR. The results of the YOLOv5 models show that the YOLOv5 new network models are able to extract rich olive features from images and detect the olive fruit with a high precision of higher than 0.75 mAP_0.5. YOLOv5s performs better for real-time olive fruit detection on the tree over other YOLOv5 variants and YOLOR

    A low-cost inkjet printing method for antenna fabrication on a polyethylene terephthalate (PET) substrate is presented in this paper. An office inkjet printer is used to have desired patterns of silver nanoparticle ink on the PET substrate without any postprocessing. Silver nanoparticle ink cures instantly as soon as it is ejected from the printer on a chemically treated PET substrate. The thickness of the silver nanoparticle layer was measured to be 300nm with a sheet resistance of as low as 0.3Ω/sq and a conductivity around 1.11 × 107 S/m with single layer deposition. A coplanar waveguide- (CPW-) fed Z-shape planar antenna on the PET substrate achieved the measured radiation efficiency of 62% and the IEEE gain of 1.44 dBi at 2.45 GHz. The printed antenna is also tested in bending conditions to ascertain its performance for the Internet of things (IoT) conformal applications for the future 5G network

    Academic language socialisation in high school writing conferences

    This study examines multilingual high school writers’ individual talk with their teachers in two advanced English language development classes to observe how such talk shapes linguistically diverse adolescents’ writing. Addressing adolescent writers’ language socialization through microethnographic discourse analysis, the author argues that teachers’ oral responses during writing conferences can either scaffold or deter students’ socialization into valued ways of using academic language for school writing. She suggests what forms of oral response provide scaffolding and what forms might limit multilingual adolescent learners’ academic literacy. Constructive interactions engaged students in dialogue about their writing, and students included content or phrasing from the interaction in their texts. Unhelpful interactions failed to foster students’ language development in observable ways. Although teachers attempted to scaffold ideas and language, they often did not guide students’ discovery of appropriate forms or points. These interactions represent restrictive academic language socialization: while some students did create academic texts, they learned little about academic language use

    Effects of hospital facilities on patient outcomes after cancer surgery: an international, prospective, observational study

    Background Early death after cancer surgery is higher in low-income and middle-income countries (LMICs) compared with in high-income countries, yet the impact of facility characteristics on early postoperative outcomes is unknown. The aim of this study was to examine the association between hospital infrastructure, resource availability, and processes on early outcomes after cancer surgery worldwide.Methods A multimethods analysis was performed as part of the GlobalSurg 3 study-a multicentre, international, prospective cohort study of patients who had surgery for breast, colorectal, or gastric cancer. The primary outcomes were 30-day mortality and 30-day major complication rates. Potentially beneficial hospital facilities were identified by variable selection to select those associated with 30-day mortality. Adjusted outcomes were determined using generalised estimating equations to account for patient characteristics and country-income group, with population stratification by hospital.Findings Between April 1, 2018, and April 23, 2019, facility-level data were collected for 9685 patients across 238 hospitals in 66 countries (91 hospitals in 20 high-income countries; 57 hospitals in 19 upper-middle-income countries; and 90 hospitals in 27 low-income to lower-middle-income countries). The availability of five hospital facilities was inversely associated with mortality: ultrasound, CT scanner, critical care unit, opioid analgesia, and oncologist. After adjustment for case-mix and country income group, hospitals with three or fewer of these facilities (62 hospitals, 1294 patients) had higher mortality compared with those with four or five (adjusted odds ratio [OR] 3.85 [95% CI 2.58-5.75]; p<0.0001), with excess mortality predominantly explained by a limited capacity to rescue following the development of major complications (63.0% vs 82.7%; OR 0.35 [0.23-0.53]; p<0.0001). Across LMICs, improvements in hospital facilities would prevent one to three deaths for every 100 patients undergoing surgery for cancer.Interpretation Hospitals with higher levels of infrastructure and resources have better outcomes after cancer surgery, independent of country income. Without urgent strengthening of hospital infrastructure and resources, the reductions in cancer-associated mortality associated with improved access will not be realised

    Initial trust in internet banking service in Jordan: Modeling and instrument validation

    Full text link
    © 2005 - 2015 JATIT & LLS. All rights reserved. As with many other e-services, the adoption rate of Internet banking services (IBS) in developing countries is relatively low compared to developed countries. It is well-established that customer’s trust plays an important role in adopting new technologies, and hence, initial trust could be the first issue that needs to be investigated when studying the adoption of online banking. The aim of this study is to develop and validate a research instrument empirically, and then use it to examine a proposed conceptual model of initial trust for IBS in developing countries. The model’s constructs are integrated from the trust literature, diffusion of innovation theory (DoI), and the Hofstede’s culture theory. This paper also aims to develop and validate a research instrument to examine the research model. We conducted a pilot study in Jordan, one of the developing countries in the Middle East. A survey was carried out, and a total of 75 responses were gathered in the study. The collected data was analyzed using IBM SPSS 22.0. Results of the pilot study are used to validate the instrument and to refine the proposed model. The validated and refined instrument will be used to examine the model in the intended primary study

    The aim of this study is to develop a unified model of initial trust for the adoption of internet banking services (IBS) in developing countries. In particular, three groups of factors have been investigated: trust literature, diffusion of innovation theory, and national culture, in order to reveal their effect on forming a customer's initial trust in IBS. We collected data using a survey and then analysed it using structural equation modelling. According to the obtained results, initial trust in internet banking services was significantly affected by: (i) factors obtained from the trust literature, which are disposition to trust, organisational structural assurance, and reputation. (ii) Relative advantages, which was adopted from the diffusion of innovation theory. (iii) Uncertainty avoidance, which is a dimension of national culture. Also, analysis of results showed a high impact of initial trust in IBS on the intention to use it. However, unlike developed countries, we found that some factors not to have noticeable influence on initial trust in IBS, such as: technical structural assurance and individualism versus collectivism
