Text Study

The article touches upon the issue of functions and features of screen text. Being generally a form of text, being expressed, semiotically separated and structured, screen text follows the same lines of general and linguistic semiotics as average texts. However, it is a multicomponent system. Among its characteristics it is possible to distinguish heterogeneity and polysemy that render it the audio-visual reflection, or rather simulation of reality. This article is a case study of a specific type of texts which are called polycode-polymodal. Logical and descriptive methods as well as observation, generalization, interpretation are the foundation of analyzing heterogeneous screen texts such as film texts, television texts and video texts of the Internet. On the exempl of various texts of visual arts and media the root process of text as specific mechanisms of framing the language used and, thus, the images and the meaning. Fundamental characteristics of the screen text – openness, psychological and aesthetic stimuli – are illustrated in descriptions of the root process. The paper contributes to revealing that the screen text obtains such features as heterogeneity, hierarchy, and polysemy, deriving from the root process of the screen text. Heterogeneity of the screen text directly influences its polysemy and makes screen text an open system. Polysemy, experience and likelihood, then, belong to the psychological stimulus; affectability, suggestive potential, suggestive infusion belong to the aesthetic stimulus. In turn, psychological and aesthetic stimuli are manifested in the screen text. Study of the root process and peculiarities of the screen text helps describe the schemes of constructing the secondary reality and simulacra on the screen, and also helps list the means of manipulation with the consciousness of the viewer in more detail.

The Difference

In this paper, I will focus on the musical work as a self-organising entity within a systemic framework. In particular, two significant and inter-related systemic concepts will be mentioned: self-organisation and open system. Firstly, I shall explain the two concepts within the context of systems thinking with reference to a graphical model of second-order cybernetics. This section will conclude with a discussion of the difference between natural and artificial self-organising systems. I will then extend the systemic perspective, describing what I call self-organising music, and discussing my algorithmic composition Ephemeron as a case study.

Policy Question

This chapter examines the policy question of how to assure quality in an open system, using the crowdsourced online encyclopaedia Wikipedia as a case study. The history of Wikipedia’s development out of another online encyclopaedia, Nupedia, is sketched, with a description of how wiki technology allowed collaborative authoring. Wikipedia compares favourably with expert-written reference books, and has helped populate the Linked Data Web via DBpedia. However, to produce good content, and minimize hoaxes and trolling controversies such as the GamerGate affair, it needs a hierarchical meritocratic management system. This has resulting in tensions, particularly along gender lines, and relatively small numbers of women participate. However, the system has if anything become more hierarchical during the COVID-19 pandemic, when it has worked hard to eliminate misinformation.

Different Dimensions

ABSTRACT To many, economics is seen as increasingly divorced from reality. I shall argue that one of the causes of this divorce is the attachment to closed-system theorising, and advocate instead the method of open systems with partial and temporary closures. Definitions of closed and open systems are examined. It is evident that there are many different criteria which may define open systems. Theorists differ in their emphasis on one or other criterion. There are also different dimensions of openness: openness to non-economic factors; the openness of economic theories themselves; the interplay of micro- and macro-economics; and the treatment of time. These are explored, using Keynes’s General Theory as a case study of an open system.

Depth Interviews

This case study examines the social institutional influence on how a nonprofit community newspaper conducts newswork. Utilizing both in-depth interviews and participant observation, the data illustrate how the government, the audience, donors and advertising impact news construction processes. The results are analyzed through both management and media sociology theories. Finally, the authors elucidate how nonprofit news organizations can optimally operate as an open-system (or organism), allowing for all peripheral social institutions to impact newswork without losing any autonomy over the journalism.
