The paper discusses the notion of information with regard to its carriers, representatives (or structural carriers) and carried-related processes of transmission, accumulation and processing through the developmental periods of the inorganic and organic world. In the first period, information is contained in a representation of the outcome of physical, chemical and other processes in the physical, chemical and other structures of the non-living world and refers to environmental information. In the second period, information begins to be used to create the physical and chemical structures of the living world and is contained in instructions of the genetic code. In the third period, with the evolution of cognitive systems and intelligence of living beings, in addition to those listed, information is finally being used to build its own structures, which in this paper are called knowledge structures.

In addition to the usual scientific methods in conceptual papers of this type (analysis, synthesis, etc.), the methodology of the paper also relies on the method of analogy, which was used to detect the carriers and representatives of information in the processes of transmission, accumulation and processing of information and the method of classification in order to propose a new taxonomy related to the concept of information.

The paper shows that information carriers and information representatives appear in each of the three mentioned processes - transmission, accumulation and processing of information - and that they need to be distinguished from the information itself. This insight opened a new perspective in observing this concept and led to the proposal of a new taxonomy related to the concept of information in a given context, eliminating seemingly incommensurable approaches to its study in different scientific fields.

The conducted synthesis results in information being recognized as a transmittable/transmissible documentation of reality inseparable from its carrier and its representative.

In line with the cognitive viewpoint on the phenomenon of information, the constructivist tradition based on Maturana and Varela's theory of knowing, and some aspects of Shannon's theory of communication, the purpose of this paper is to shed more light on the role of information, data, and knowledge in the cognitive system (domain) of the observer.

In addition to the literature review, a proposed description of the communication and knowledge acquisition processes within the observer's cognitive system/domain is elaborated.

The paper recognizes communication and knowledge acquisition as separate processes based on two roles of information within the observer's cognitive system, which are emphasized. The first role is connected with the appropriate communication aspects of Shannon's theory related to encoding cognitive entities in the cognitive domain as data representations for calculating their informativeness. The second role involves establishing relations between cognitive entities encoded as data representations through the knowledge acquisition process in the observer's cognitive domain.

In this way, according to the cognitive viewpoint, communication and knowledge acquisition processes are recognized as important aspects of the cognitive process as a whole. In line with such a theoretical approach, the paper seeks to provide an extension of Shannon's original idea, intending to involve the observer's knowledge structure as an important framework for the deepening of information theory.

The purpose of this paper is to propose an appropriate symbolic representation, as well as its metaphorical interpretation, to illustrate the special role of information in the knowledge acquisition process.

Besides the literature review, this is a speculative study based on a symbolic and metaphorical point of view.

The proposed symbolic representation was derived from the conceptual designation of information “as a flow” and, accordingly, by the corresponding redrawing of the data-information-knowledge-wisdom (DIKW) pyramid. The knowledge acquisition process is symbolically represented by the growth of a “tree of knowledge” which is planted on a “data earth,” filled with “information sap” and lit by the rays of the “sun of the mind,” a new symbol of the concept of wisdom in the DIKW model. As indicated, a key concept of this metaphorical interpretation is the role of “information sap” which rises from the roots of the “tree of knowledge” to the top of the tree and it is recognized as an invisible link between “world of data” and “world of knowledge.” This concept is also proposed as a new symbolic representation of the DIKW model.

On the basis of specific symbolic-metaphorical representation, this paper provides a relatively new concept of information which may help bridge observed gaps in the understanding of information in various scientific fields, as well as in its understanding as an objective or subjective phenomenon.

While the library has remained a preferred place of learning and received a positive perception in all aspects, the current space planning, as categorized in the “four-space model,” does not seem to address user needs well. The purpose of this article is to explore the correlations of user perceptions, academic library usage and social capital.

This research presented a new approach to understanding the academic library's role by surveying 120 users about their preferred place on the campus, actual usage, and perceptions of the library physically and remotely. Correlation analysis between library use and user activities was performed.

The findings indicate that the library demonstrates attributes from all four levels in the learning space hierarchy, providing an ideal learning space for students. However, our results do not support academic libraries as the breeding ground of social capital.

As the data of this study were collected during the COVID-19 pandemic period, the findings may provide us with insights on how library users have adjusted themselves in using these public facilities with social distancing in their minds. The findings also provide implications for re-designing the library places to meet the users' needs and make it favorable learning commons to students in both the pandemic and post-pandemic eras.
