However, existing works are not able to present the cloud federation management aspect or implement these properties that distinguish cloud federation from other inter-cloud organizations. This paper bridges this gap by proposing a managed cloud federation architecture based on this subset of properties. The key component of this architecture is the federation manager that controls, tracks, evaluates, and predicts the behavior of the federation. In order to ensure the effectiveness of the approach, the authors developed the Managed Federation Simulator to implement the proposed federation architecture on the SmartFed simulator and evaluate it through a set of scenarios on a real case study.","PeriodicalId":296080,"journal":{"name":"J.

Numerous challenges have limited access to mental health services. Some of these barriers have included transportation, number of providers, poverty, and lack of insurance. Recently, the utilization of telepsychiatry has increased in rural areas. The purpose of this review was to identify and coalesce the benefits of telepsychiatry for adults living in rural communities in the United States to determine if telepsychiatry has improved access and quality of care. The methodology for this study was a literature review that followed a systematic approach. References and sources were written in English and were taken from studies in the United States between 2004 and 2018 to keep this review current. Fifty-nine references were selected from five databases. It was found that several studies supported that telepsychiatry has improved access and quality of care available in rural environments. At the same time, telepsychiatry in mental healthcare has not been utilized as it should in rural adult populations due to lack of access, an overall shortage of providers, and poor distribution of psychiatrists. There are numerous benefits to implementing telepsychiatry in rural areas. While there are still barriers that prevent widespread utilization, telepsychiatry can improve mental health outcomes by linking rural patients to high-quality mental healthcare services that follow evidence-based care and best practices. Telepsychiatry utilization in rural areas in the United States has demonstrated to have a significant ability to transform mental health care delivery and clinician productivity. As technology continues to advance access, telepsychiatry will also advance, making access more readily available.","PeriodicalId":296080,"journal":{"name":"J. Inf. Technol.

This paper presents a heterogeneous weighted voting-based ensemble (HWVE) model for root-cause analysis. The proposed model is composed of an aspect extraction and filtering module, a model-based sentiment identification module, and a ranking module. Domain-based aspect ontologies are created using the available training data and is used for categorization. The input data is passed to the HWVE model for opinion identification and is in-parallel passed to the significance identification phase for aspect identification. The identified aspects are combined with their corresponding sentiments and ranked based on their ontological occurrence levels to provide the final categorized root-causes. Experiments were performed with the five-product dataset, and comparisons were performed with recent models. Results indicate that the proposed model exhibits improved performances of 5%-13% in terms of F-measure when compared to other models.","PeriodicalId":296080,"journal":{"name":"J. Inf. Technol.

Virtualization makes the resources available to the public to use without any concern for ownership or maintenance cost. In addition, the hosted applications in cloud computing platforms are highly interactive and require intensive resources. The new trend is to duplicate these applications in multiple virtual machines based on demand. Such a scheme needs an efficient resource provisioning to manage the resource assignment to multiple virtual machines properly. One of the issues in the current resource provisioning technique is assigning the resources proactively without predicting the workload of hosted applications, which cause load imbalance and resource wasting. Thus, this paper proposes a new model to predict the application workload. The experimental results show the ability of the proposed model to allocate more virtual machines and to balance the workload among the physical machines.","PeriodicalId":296080,"journal":{"name":"J.

PoC practices are poorly explored and characterized in the scientific literature. The motivation of this research is the clarification of an approach to PoC. This article introduces a “new” and different view of PoC practices using Activity Theory and Hermeneutics. The authors debate that it is not possible to understand the whole PoC until its constituent parts and context have been understood. Therefore, the process of appropriation of knowledge in PoC occurs in social interaction between one practitioner and another, through an activity that is mediated in the relations between those practitioners, and an activity between the triad—subject (practitioner), object of learning (outcome), and mediating artifacts—with the aim of improving PoC practices.","PeriodicalId":296080,"journal":{"name":"J.

Due to this noise, diagnosis remains inaccurate. Thus, removal of noise becomes a very important task when dealing with MR images. In this paper, a denoising method has been discussed that makes use of non-local means filter and discrete total variation method. The proposed approach has been compared with other noise removal techniques like non-local means filter, anisotropic diffusion, total variation, and discrete total variation method, and it proves to be effective in reducing noise. The performance of various denoising methods is compared on basis of metrics such as peak signal-to-noise ratio (PSNR), mean square error (MSE), universal image quality index (UQI), and structure similarity index (SSIM) values. This method has been tested for various noise levels, and it outperformed other existing noise removal techniques, without blurring the image.","PeriodicalId":296080,"journal":{"name":"J. Inf.

The results were obtained by consulting two major scientific databases, namely, Scopus and the Web of Science, which provided 136 articles published on the social environment from 2011 through to mid-2016 using the term gamification. The results of this study reveal how over time gamification has been gaining importance in the social environment through the use of its components. The highest number of scientific publications come from the United States and Spain. In addition, the use of gaming components increases motivation and engagement.

Each of these users publishes text messages with their opinions, concerns, information, or simply their daily happenings. It is a challenge to address the analysis of massive data in the network, just as it is an objective to look for ways to understand everything that data can offer today in terms of knowledge of society and the market. The sector of science communication is still discovering everything that the web 2.0 and social networks can offer to reach all audiences. This article develops a classification model of messages launched on Twitter, on science topics, in Spanish, with machine learning techniques. The training of this type of models requires the creation of a specific corpus in Spanish for the subject of science, which is one of the most laborious tasks. The classifier is able to predict the sentiment of the message in real time on Twitter, with a confidence interval greater than 80%.

The traditional configuration of most school classrooms must be reconsidered to allow for changes in the educational paradigm to support ICT for learning. It is not clear which environmental aspects should be modified to improve performance in physical learning environments (LE), especially to accommodate hybrid models in classrooms. This article describes the process used to understand education conditions for attending to student needs, the connection between the LE, new technologies, and a social climate favourable to educational changes. This study was carried out in a public secondary school in North-eastern Brazil and adopted a design science research method to perform a participatory design exercise, to develop new classroom environment concepts.
