The Subject

In a course of thermodynamics, in general, and gas turbine analysis, in particular as stand alone or within a cogeneration situation, teaching within the concepts of energy or exergy has become controversial particularly since most teachers of thermodynamics at the undergraduate level are not too familiar with the advantages of exergy analysis and thus do not cover the material from that point of view. In this paper, we will go through the pedagogical implications of teaching thermodynamics using both approaches and attempt to show and convince people that exergetic analyses are superior to any other approach in the teaching of thermodynamics. The bottom line and the ultimate goal is the precise teaching of the subject matter.

The article summarizes the key points in the development of the metadialogue phenomenon from a linguistic point of view. Some stages of the development of this concept and the difficulties associated with its structuring are covered. The main research findings of modern foreign and domestic experts on its study are considered. Some characteristics of the subject of the research from the standpoint of various pragmatic installations are given. On the basis of the dynamic structure of the metadialogue development, certain principles of semantic relations connected with the dialectical nature of human cognition are presented. Excursion into the history and evolution of the concept is presented. Several types of formulation of the subject matter are given. In accordance with the goal of speech exposure, internal problems of the development of metadialogue are highlighted and the critical points related to solving these problems are described. The rules of metadialogue flow are explained at the level of steps, the success/failure of which directly affects the final result of communication. The prospects of development of the concept research in accordance with various types of discourse are indicated.

Authors in this contribution focus on issue of subject matter structure creation by the teacher as an important psycho-didactic domain of education process and how does a student perceive this structure. The aim of the teacher is not only to impart the knowledge to students but also to show them and teach them possible ways of how to understand the subject matter better and how to get to the fundamentals of it. Based on the structure of subject matter created by the teacher a student creates cognitive frames which become basis for his further learning. We pay attention to definition of epistemology of subject matter structure, questions of psycho-didactic approach to teaching, creating structure of subject matter and how does the teacher work with the text. Empirical part of the contribution investigates teachers' preferences of subject matter structure and statistically describes subjective perception of level of understanding of the subject matter by a student influenced by the particular subject matter structure realized by the teacher.

Purpose This paper aims to provide guidance on cloud computing assurance from an IT governance point of view. The board and executive management are tasked with ensuring proper governance of organizations, which should in the end contribute to a sense of assurance. Assurance is understood to be a part of corporate governance which provides stakeholders with confidence in a subject matter by evaluating evidence about that subject matter. Evidence will include proof that proper controls and structures are in place, that risks are managed and that compliance with internal and external requirements is demonstrated with regard to the subject matter. Decisions regarding the use of cloud computing in organizations bring these responsibilities to the fore. Design/methodology/approach The design of this paper is based on an extensive review of literature, predominantly best practices and standards, from the fields covering IT governance, cloud computing and assurance. Findings The results from this paper can be used to formulate cloud computing assurance evidence statements, as part of IT governance mandates. Originality/value This paper aims to add value by highlighting the responsibility of managers to ensure assurance when exploiting opportunities presented through IT advances, such as cloud computing; serving to inform management about the advances that have and are being made in the field of cloud computing guidelines; and motivating that these guidelines be used for assurance on behalf of organizations adopting and using cloud computing.

The COVID-19 is an ongoing global pandemic, caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). The virus was first identified in December 2019 in Wuhan, China. The COVID-19 pandemic in 2020 resulted in the abrupt shutting of all the educational institutions (schools, colleges, and universities) in India. This resulted in dramatic changes in the education system with the distinctive rise of e-learning, whereby teaching is undertaken remotely and on digital platforms. Online learning is a competent and contactless method of teaching to remotely located students. Geography is a branch of science which deals with the study of the earth’s surface and the relationships between people and their environment. Geographers explore both the physical properties of the earth’s surface and the human societies spread across it. The subject matter of Geography containing different theory papers and practical papers cannot just be effectively taught in a classroom or laboratory but best enlightened on the field. For the effective learning process in the subject of Geography, students require on-ground observations, laboratory analysis, projects and dissertations, field surveying, computer mapping and analysis, field trips and excursions, etc. It helps the budding Geographers to acquire not only theoretical knowledge but also practical skills. But the COVID-19 pandemic situation confronted the education system, forcing the educators in the field of Geography to shift to an online mode of teaching, leaving them with no option. During this crisis, the educators have given their best in teaching the subject matter of Geography to the students by using various open-source teaching aids by overcoming the issues like lack of training and professional technical support. This altered the traditional teaching and learning process in the field of Geography, which essentially affects the students of Geography. Thus, a case study was undertaken to assess the online teaching in the subject of Geography at the undergraduate level during the academic year 2020-21 from the student’s perspective.

The article is devoted to clarification of the phenomenon and logics included into the subject of forensic science. The author criticizes attempts of other commentators to extend the subject matter of this science as well as the statements about so-called crisis in forensic science in Russia. From the author’s point of view, there is no reason to speak about a crisis. At the same time, it is necessfry to specify the subject matter of forensic science. The author argues against extension of the subject matter of forensic science to the fields of civil procedure and arbitration. He believes that the main aim of science has been still to detect a trace picture of a crime. So, forensic science is primarily in the field of fighting crime. Only powerful bodies and officials carry out forensic activities. As for the other subjects (such as advocates) – they can only use the achievements of forensic sciences. The author analyzes positions of Russian (including Soviet) and German commentators. The analysis allowed the author to propose the definitions of forensic science and criminalistical (forensic) characteristics of crime.

The Way

In this paper we describe findings concerning a limited part of teacher behaviour namely relational skills. These skills are of vital importance if a teacher is to create a good classroom atmosphere. On the basis of theories of Leary (1957) and Watzlawick et al. (1968) we have constructed a model that describes relational aspects of teacher behaviour. This model focusses on teacher behaviour as revealed in teacher pupil interactions. These interactions are analysed by means of the system theory of communication. We have investigated teacher behaviour as observed by teachers and pupils, with the help of an instrument called 'The Questionnaire for Interactional Teacher Behaviour'. It is found that from the pupils' point of view good teachers are distinguished from bad teachers by the amount of kindness and understanding they show, their helpfulness and the way they manage a class. We also investigated the behaviour that teachers themselves wish to display. They agree about the need to be kind, helpful and understanding but differ in the amount of strict behaviour they want to display and in the amount of freedom and independence they want to give to pupils. We also investigated with this questionnaire the teacher behaviour of teachers who teach different subjects. It is found that pupils consider modern language teachers in particular to behave differently from other teachers; they are stricter, less kind and give less independence to pupils. This different behaviour of modern language teachers may be due to the structure of the subject matter, or to the way in which languages are taught at universities to future teachers. We think teacher trainers should be concerned with our findings because when teachers, and particularly language teachers, become older they seem to have increasing difficulty in creating and maintaining an adequate relationship with their pupils.

Conspiracy Thinking

Disrespect for the truth, the rise of conspiracy thinking, and a pervasive distrust in experts are widespread features of the post-truth condition in current politics and public opinion. Among the many good explanations of these phenomena there is one that is only rarely discussed: that something is wrong with our deeply entrenched intellectual standards of (i) using our own critical thinking without any restriction and (ii) respecting the judgment of every rational agent as epistemically relevant. This chapter argues that these two Enlightenment principles—the Principle of Unrestricted Critical Thinking and the Principle of Democratic Reason—not only conflict with what is rationally required from a purely epistemic point of view, but also further the spread of conspiracy theories and undermine trust in experts. As a result, we should typically defer to experts without using any of our own reasons regarding the subject matter

The Subject

The phrase ‘a theology of nature’ is an abbreviation for ‘a theological account of natural happenings’—happenings which are properly investigated in the first instance by appropriate ‘natural sciences’. A Christian theology of nature seeks to provide a systematic appreciation of the physical universe, its items and occurrences, from a Christian theological point of view. If it is to rank as a serious contribution to human wisdom, it must be a disciplined effort to understand in appropriate terms the object of interest. One version of the discipline would be to produce an extension of the natural sciences, to cover topics—God, freedom, immortality—which fall outside their scope by a ‘metaphysical’ science which links these topics to the subject-matter of natural sciences in a theoretical account of ‘being as such’. This would have the effect of reintroducing ‘Natural Theology’, reshaped and revitalised, into the fabric of Christian systematic theology. This project is not being advocated in this article. It is mentioned solely in order to distinguish the present topic, a ‘theology of nature’, from what is traditionally known as ‘natural theology’. The purpose of this article is to explore afresh the structure of Christian intellectual response to the wonder of the world, as it is now being analysed by science, with particular attention to the ‘evolutionary’ aspect of things, appreciation of which has radically affected modern sensibility.
