In this study we document how a mathematical idea, shared by a student, changes the development of the class discussion. Our work characterizes the flexible and open dynamics in mathematics instruction that a teacher adopts to give her students control of their own mathematical ideas. Our work argues that this flexibility is necessary for teachers to engage in instructional practices that respond to students' mathematical thinking. To demonstrate the teacher's flexibility we use the analogy of soccer, relying on the literature of Game Sense coaching approach, which suggests that the coach (the teacher in our context) is positioned to manipulate the practice environment with the purpose of facilitating learning.

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]

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.

In this study, the elements of the design and results of the implementation of a Massive Open Online Course (MOOC) based on the problem solving and the use of digital technology are analyzed and discussed. The results show that the design of the activities, the intervention of the MOOC design team in the discussion forums and the interaction among the participants allowed and favored the creation of a collaborative environment in problem solving. Participants shared and discussed their mathematical ideas, as part of a virtual learning community, which allowed them to formulate conjectures, explore and search properties to sustain relationships, and communicate results.

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.
