A review on modelling and dynamic analysis of viscoelastic rotor systems

Purpose The purpose of this study is to bring down collective information about various issues encountered in modelling of rotor systems. Design/methodology/approach The most important and basic part of “rotor dynamics” is the study related to its different modelling techniques which further involves the analysis of shaft for understanding the system potential, competence and reliability. The issues addressed in this study are classified mainly into two parts: the initial part gives out a vast overview of significant problems as well as different techniques applied to encounter modelling of rotor systems, while the latter part of the study describes the post-processing problem that occurs while performing the dynamic analysis. Findings The review incorporates the most important research works that have already placed a benchmark right from the beginning as well as the recent works that are still being carried out to further produce better outcomes. The review concludes with the modal analysis of rotor shaft to show the importance of mathematical model through its dynamic behaviour. Originality/value A critical literature review on the modelling techniques of rotor shaft systems is provided from earliest to latest along with its real-time application in different research and industrial fields.

Educators as Facilitators of Game-Based Learning

Innovative educational methods such as gamification are gaining ground in more formal environments and have great potential to improve learning in education. However, the implementation of this strategy in the classroom is assumed to be a complex practice for beginners and requires the development of new competencies by educators. This chapter aims to contribute to the advancement of knowledge about the main competencies needed for educators to perform as facilitators of educational games. The study was developed through critical literature review, interviews, and questionnaires. The outcome is the development of a framework of competencies of an educator willing to use game-based learning. The study highlights the importance of institutional support to boost the development of pedagogical, technological, and social skills among educators. The conclusions of the chapter are valuable for educators aiming to adopt game-based learning and to higher education decision makers committed to expanding innovative learning contexts on their institutions.

Measuring the Use of Mobile Applications in Higher Education

The proliferation of use of mobile applications has increased access to information and the way we communicate and collaborate. Higher education institutions must follow this trend and cannot ignore this. They should make efforts to integrate them in their routines, namely in their students. This chapter aims to extend the understanding about the actual use of mobile applications and how users report using them, namely in the classrooms. The main objective of this literature review is to conduct a critical literature review on this use. For this purpose, an analysis of several articles in reference publishers and journals was carried out. As a result of the analysis and cross-checking of literature data, it could be concluded that the use of mobile applications that users make and the one they claim to make may differ. It is intended to understand this problematic and analyse methods that may result in more precise data in this context. These data may be used, for example, to define strategies, namely helping higher institutions defining the use of m-learning.

Style and Stylistics

Style and stylistics are two critical terms, that they exceed Kurdish modern criticism in the spread of researching modern critical literature of people and modern Kurdish literature. Style is a wide range of using language, stylistics is a researchable science and it is the detail of the styles. Modern linguistics that (Bale) invented, paves the way for the emergence of this modern science for studying style, how modern linguistics studies (speech) and likewise stylistics studies styles of speech. This research sheds light on these two terms.

The problem of modern literary criticism between tradition and renewal: The theory of receive and interpretation : إشكالية النقد الأدبي الحديث بين التقليد والتجديد "نظرية التلقي والتأويل"

Identifying the concept of a text, its analysis and interpretation are of great importance in literary critical studies among western and Arab scientists and researchers of all time. This theory was rooted in Arabic Rhetoric and interpretation of Holy Qura'n before the existence of modern linguistics and western theories. Recently, the text- reader relation has been developed in light of these grounded theories assuring that the base of the literary work in the interaction between the text construction and its readers. This interaction is mainly attained from the real interactivity between them both through receive theory as the recipient gets involved expecting something. The most important point is that reading should be productive by adding new dimensions and unlimited to the barriers of the text. The problems of reading and interpretation revolve around two main axes; first, the literary work and nature of the text, second, the interpretation and understanding of the text. Then, the issue is related to the subjectivity and objectivity of the text, and the degree of the reader's understanding and interpretation of it. So, it is a harmonized system that collects the elements of creativity; the author, the reader and the text when relating reading process to receive mechanics and interpretation. The current results confirmed that Arabic Rhetoric and critical literature have significant roles in the treatment of the text and its components.

PRESERVING IDENTITY OF HISTORICAL ENVIRONMENTS IN SIBERIA: A CRITICAL LITERATURE REVIEW

Introduction: Currently, the projects related to the development of identical historical environments in Siberia, Russia, are predominately inconsistent. Yet there is an opportunity to find a more holistic approach to sustaining local heritage, which could address local cultures and identities through an understanding of how the location, as well as specific spatial and architectural practices, evolve. Purpose of the study: The study aimed to establish a theoretical and methodological framework for sustaining the local identity in architectural terms. Methods: According to the methodological recommendations of Groat and Wang, such methods as critical literature review and logical argumentation were used. Results: The research came to the conclusion that the city identity can be unfolded through two or more congruent layers of existence. This study deals with architectural heritage and society as two types of such layers. It suggests that the local identities of historical environments could be sustained by a combination of the following methods: 1) looking to the past, through analyzing the city’s fabric and searching for “social traces” and semiotic meanings; 2) looking to the future, through using participatory design methods. This methodology should be further tested on specific historical environments in Siberia. The critical literature review will provide researchers and practitioners in the field with a fundamental theoretical framework.

Indigenous parents and child welfare: Mistrust, epistemic injustice, and training

The settler state's taking of Indigenous children into care disrupts their communities and continues destructive, assimilationist policies. This article presents the perceptions of lawyers, social workers and judges of how Indigenous parents experience child welfare in Quebec. Our participants characterized those experiences negatively. Barriers of language and culture as well as mistrust impede meaningful participation. Parents experience epistemic injustice, wronged in their capacity as knowers. Mistrust also hampers efforts to include Indigenous workers in the system. Emphasizing state workers’ ignorance of Indigenous family practices and the harms of settler colonialism, participants called for greater training. But critical literature on professional education signals the limits of such training to change institutions. Our findings reinforce the jurisdictional calls away from improving the system towards empowering Indigenous peoples to run services of child welfare. The patterns detected and theoretical resources used are relevant to researchers of other institutions that interact with vulnerable populations.

Making land grabbable: Stealthy dispossessions by conservation in Ngorongoro Conservation Area, Tanzania

This paper seeks to answer the question: how does land become grabbable and local people relocatable? It focuses on the historical and current conditions of land tenure that enable land grabbing. While recognising the important contributions thus far made by the critical literature on land grabbing, this paper moves forward towards understanding specific processes that befall before land is grabbed and its original users relocated. Based on an empirical analysis of policy and practices of the Ngorongoro Conservation Area in Tanzania, the paper proposes that land grabbing, particularly in the context of conservation in rural Africa, is not an instantaneous phenomenon and does not happen in a vacuum. It is a result of long-term structural marginalisation of rural land users that produces scarcity and the deterioration of life conditions, which make people relocatable and land grabbing justifiable. Local people either relocate themselves because they could not make a living due to systematic disinvestments on basic social services or life is made unbearable through restrictions imposed on their production practices to make “voluntary” relocation possible. The paper highlights the need to focus on the stealthy dispossessions in addition to major events of grabbing as starting points of analysis. Insight from this study can be useful in analysing other cases of land grabbing where large swathes of ostensibly empty land are made available for investment.
