In this paper, we proposed a model of security capabilities to prevent personal health data leakage in Big Data environments. There are new threats and risks in every organization in the health sector, among which the leakage of personal data stands out as the amount of digital information about a patient or employee circulates in networks, equipment, and systems. The proposed model allows the healthcare entity to measure the level of maturity of its organization by identifying how robust it is to prevent data leakage scenarios, as well as to identify existing gaps and shortcomings. This proposal allows healthcare organizations to establish remediation measures in those domains with a deficient level, acting preventively before the risk event materializes. The model incorporates 10 domains with the best practices of NIST, which have allowed an analysis to be carried out to obtain a greater scope of all the necessary edges to have an adequate level of prevention in the organization. The structure of the model is made up of three phases: 1. Diagnosis of the organization by using the proposed model through a questionnaire; 2. Collection and processing of the results divided into 3 sub-phases: 2.1 Review and measurement of the results of the answers, 2.2 Analysis based on criteria from 1 to 5, and 2.3 Level of maturity obtained; 3. The proposal was validated in private health organizations in Lima, Peru. Preliminary results show a trend of security deficiencies in the same domains for the companies evaluated.

This paper describes our work to determine the naturalistic images that first-time secondsemester university calculus students possess for series convergence. We found that the students we interviewed most frequently determined whether a series converged by imagining a process of appending summands into a running total and examining whether this running total appeared to approach an asymptotic value. We provide examples and three corresponding implications of this "asymptotic running total" that informed students' actions while determining series convergence or the value of convergence. Our paper adds to the research literature by confirming students' meanings for limits reported for other topics (e.g., limit of sequence, function, Taylor series) apply to infinite series and proposing relationships between previously reported meanings for series convergence.

The reasonable integration of technologies as well as the consideration of customer needs alike are crucial when the position of a company shall be perceived as innovative and successful. Especially low and medium technology enterprises in the service industry often struggle with technology integration as they lack knowledge and resources to carry out technology analysis and integration. The importance of technology integration in the services sector is part of many studies. However there is little to no evidence on how, for example, a service company in a non-technological industry can carry out successful technology integration. The focus of the process model for technology potential analysis used for the study and the methodology lies on low and medium technology enterprises, specifically on enterprises in the non-technological service industry. Albeit, the approach, which shows the taken steps as a procedural model, can be used by any company in order to incorporate new technologies into their products or services. The determination of customer needs and application fields for a chosen technology form an integral part of this paper. For the case study a company in the food service industry (restaurant) was selected and the technology to be investigated was the NFC-Technology. The field study portrayed in this paper is using this procedural model as guideline to evaluate the potential of the NFC technology in the food service industry. It aims to determine tangible customer needs, actual application fields for the NFC-technology in the food service industry (restaurant) and highlights the possible implementations of the findings The first part of the paper deals with a technology based analysis of NFC and its functions and an analysis of the processes and activities within the food service industry. The second part forms a customer need analysis and a matching thereof with previously analysed NFC application fields. [ABSTRACT FROM AUTHOR]

A toolkit of methods assisting inventive thinking called "Theory of Inventive Problem Solving (TRIZ)" was introduced by Altshuller (1956). TRIZ is nowadays gaining the popularity among practitioners and academy, indicated in steadily growing number of scientific publications. This paper conducts systematic literature review aiming at application of TRIZ in management. Our findings reveal that TRIZ, or some tools of TRIZ, like contradiction analysis and "Ideal final result" concept, are most commonly applied in innovation management particularly in Ideation and Implementation stages. We also acknowledge accompanying methodologies that are used in combination with TRIZ. Except of the benefits of TRIZ tools, results confirmed the problems of methodological complexity, expert-dependency, increased subjectivity, weak integration with IT tools and lack of industry verification cases.

Although labor and working conditions are generally specified when an English Language Teacher (ELT) is hired, not many schools follow these job specifications in the real practice, the reasons for this are diverse in the educative system. This paper aims at exploring what teachers consider satisfying and challenging conditions from a work place and the reasons that have made them change their jobs. Online structured questionnaires with open-ended questions were conducted with four ELTs. Those teachers have worked in public and private schools of diverse educative levels in the State of Mexico. This study was carried out under a qualitative paradigm while exploring the teachers' perceptions of working conditions. The recollections were read and compared by coding the data from the questionnaires. The findings mean to show reasons of teachers' drop out. Implications will be drawn throughout the analysis of the questionnaires and suggestions for future research. [ABSTRACT FROM AUTHOR]

Edge computing (EC) is a recent computing paradigm in the IoT domain for performing calculations and processing at the edge of the network, closer to the user instead of moving all data to the cloud. In this way, EC practitioners aim to replicate the benefits of cloud computing but closer to the source of the data, reducing the latency imposed by the distance between the cloud and the end devices, the network overhead, and the security and privacy risk that this offloading entails. But not only that. EC practitioners also aim to replicate best practices used on cloud-native development and operation. In this regard, GitOps is one of the main trends in the DevOps ecosystem for Continuous Deployment (CD) that promotes infrastructure automation in highly distributed applications, accelerating value delivery while avoiding error-prone manual processes. Till now, GitOps has been mainly related to Kubernetes--a widely used container orchestration platform to run distributed applications resiliently. In this regard, more and more IoT EC solutions are implementing container orchestration solutions like Kubernetes, thus, it is worthwhile identifying the benefits that GitOps adoption could leverage at the Edge and how possible challenges and drawbacks could be addressed. This paper presents a proof of concept based on tools included in the Cloud Native Computing Foundation (CNCF) landscape to check the feasibility of applying GtiOps in IoT EC solutions. Several drawbacks were detected mainly due to the used tooling, such as lack of automatic provisioning of physical infrastructure, tight coupled to Kubernetes descriptors for declaring workloads, and limitations on the edge devices that can be supported.

The number of online reviews increase considerably on platforms and have a significant impact on purchase decisions. These reviews can represent both an opportunity and a threat for a company. It is therefore essential to detect among the huge quantity of reviews, those which are unreliable. A question then arises: how to detect deceptive reviews? In this paper, we were interested in the concept of review trustworthiness. To detect the reliability of reviews, we give our definition of the reliability and propose a machine learning approach based on different classifiers. We consider that the information related to the comment itself (sentiments, linguistic elements etc.), and that relating to the user (activity, experience, sociability etc.) play a role on reliability of the review. We propose to include in our method these two classes of information. We did a series of experiments on the Yelp open dataset. Furthermore, in these experiments we have compared the performances of our trust model with a second model based only on the review's content (using TF-IDF vectorisation method). Our results show on the one hand that the information we used (comments+users) play a role in determining the reliability of the review, and on the other hand that we achieve better performances with our features (i.e. without using TFIDF method).

New reality imposed by months of quarantine days caused by the global spread of COVID-19 affected mostly every industry. In this new digital age, new technologies are being incorporated continuously introducing new shapes of businesses. Companies able to adapt have a high probability of survival but, even now, digital transformation is still a challenge for traditional nondigital companies. A digital business strategy could guide the inevitable transformations that digital technologies trigger. This paper presents a systematic review of current literature on digital (business and/or transformation) strategies with the objective to identify, evaluate and interpret published research that could bring some light to the relevant aspects and pitfalls that should be considered in a digital transformation initiative. The review investigates what is known about the risks and multi-industry aspects in a digital strategy and the results show statistical data, gaps in current research and models of successful implementation.
