Modelling Bioeconomy Scenario Pathways for the Forest Products Markets with Emerging Lignocellulosic Products

The forest-based sector plays diverse roles among the emerging bio-based industries. The goal of this study is to examine how forest product markets could develop in the face of a growing bioeconomy and which interdependencies occur between traditional and emerging forest-based sectors. Therefore, we analyze the development of dissolving pulp together with lignocellulose-based textile fibres and chemical derivatives in a partial equilibrium model. For this purpose, we extend the product structure of the Global Forest Products Model (GFPM) and analyze three different bioeconomy scenarios from 2015 to 2050. The simulation results show that, in a scenario where the world is changing toward a sustainable bio-economy, wood consumption patterns shift away from fuelwood (−30% by 2050) and classical paper products (−32% by 2050) towards emerging wood-based products. In this context, the dissolving pulp subsector could outpace the continuously shrinking paper pulp subsector by 2050. To develop in this way, the dissolving pulp subsector mainly uses released resources from the decreasing paper pulp production. Simultaneously, wood-based panels are finding increasing application (+196% by 2050) and thus are taking over potential markets for sawn wood, for which production growth remains limited. Our results also show that, until 2050, the production of many wood-based products will take place mainly in Asia instead of North America and Europe.

On functional moduli of surface flows

Currently, an complete topological classification has been obtained with respect to the topological equivalence of Morse-Smale flows, [9, 7], as well as their generalizations of Ω-stable flows on closed surfaces, [4]. Some results on topological conjugacy classification for such systems are also known. In particular, the coincidence of the classes of topological equivalence and conjugacy of gradient-like flows (Morse-Smale flows without periodic orbits) was established in [3]. In the classical paper [8], it was proved that in the presence of connections (coincidence of saddle separatrices), the topological equivalence class of a Ω-stable flow splits into a continuum of topological conjugacy classes (has moduli). Obviously, each periodic orbit also generates at least one modulus associated with the period of that orbit. In the present work, it was established that the presence of a cell in a flow bounded by two limit cycles leads to the existence of an infinitely many stability moduli. In addition, a criterion for the topological conjugation of flows on such cells was found.

Narratives: the rhetoric of intentional action

Purpose The purpose of this paper is twofold: first, to clarify that narratives have a rhetorical dimension, whose study has to be considered an important part of rhetoric (this claim is not accepted by important scholars). The arguments are based on the properties that narratives are very persuasive and that they are implicitly involved in the three species of rhetoric (deliberative, judicial and celebrative) introduced by Aristotle in his Rhetoric. Second, narratives are strongly related to the concept of intentional action or human action that has a purpose, a mental project and the execution of the act, such it is defined in the classical paper by Alfred Schutz common-sense and scientific interpretation of human action (1953). This property relates narratives with phenomenology, epistemology of social sciences and management research and practice. Design/methodology/approach This research is a theoretical work based on the study of central concepts of rhetoric, narratives, historiography and epistemology of social sciences and it uncovers the narrative aspects involved in intentional action. As a theoretical study, it does not include empirical studies, but it points out some kinds of management activities, such as creating projects and case studies. Findings It uncovers the relationships between rhetoric and narratives, and between narratives and intentional action. If offers a new conceptual frame that can be very productive. Originality/value This conceptual approach is new. It clarifies important misunderstandings about narrativity, facts, meanings and interpretations.

Building Ferroelectric from the Bottom Up: The Machine Learning Analysis of the Atomic-Scale Ferroelectric Distortions

<div>Recent advances in scanning transmission electron microscopy (STEM) have enabled direct visualization of the atomic structure of ferroic materials, enabling the determination of atomic column positions with ~pm precision. This, in turn, enabled direct mapping of ferroelectric and ferroelastic order parameter fields via the top-down approach, where the atomic coordinates are directly mapped on the mesoscopic order parameters. Here, we explore the alternative bottom-up approach, where the atomic coordinates derived from the STEM image are used to explore the extant atomic displacement patterns in the material and build the collection of the building blocks for the distorted lattice. This approach is illustrated for the La-doped BiFeO₃ system.</div><div>The full analysis procedure is available as an interactive paper in a form of a Google Colab (Jupyter) notebook where a classical paper organization is augmented with code cells that appear hidden by default (when viewed in Google Colab). This should allow a reader to retrace the analysis and, more importantly, it enables the readers to use the same codes for their data. The same paper is also available in a standard pdf format (without code).<br></div>

Besides, it also has an important role of teaching materials for teachers and students, the learning is done individually, and classical groups.

Is popular culture the “least cultural denominator”? An analysis of fiction readership in Russia

In his now-classical paper, Paul DiMaggio (1987) claimed that popular culture in modern societies “provide(s) stuff of everyday sociability”. It serves to bridge cultural holes between major social groups patronizing different artistic genres. Intuitively appealing and grounded in a long tradition of theorizing on “mass culture”, the proposition that low-brow art serves as the “least cultural denominator”, however, has been scarcely empirically tested. We developed a dual network approach to testing this proposition. We use data on readership in St. Petersburg, Russia, from the city’s municipal public library system (above 1.300.000 records) to reconstruct a network of 22.000 authors. With this, we demonstrate that counter to DiMaggio and others, authors with predominantly university-educated readership are more likely to bridge cultural holes in taste networks, as measured by weighted betweenness and constraint. We interpret this as a sign that, at least as far as the literature is concerned, it is the relatively high-brow, rather than low-brow, artistic figures that are more likely to serve to bridge cultural holes providing themes for “culture talk” (Lizardo) across large social distances. We discuss three explanations for this fact: institutional (the central role of educational institutions in distribution of literature, in contrast to cinema and other predominantly commercial art forms), structural (we claim that the centrality of high-brow tastes is implicated by Peterson’s omnivorousness model) and taste (more educated audiences prefer cultural products transgressing traditional genre boundaries). We argue that the evidence points in the direction of a combination of all three explanations.

Eshelby's tensor for embedded inclusions and the Elasto-Capillary phenomenon

The elastic state of an embedded inclusion undergoing a stress-free transformation strain was the subject of John Douglas Eshelby's now classical paper in 1957. This paper, the subject of which is now widely known as “Eshelby's inclusion problem”, is arguably one of the most cited papers in solid mechanics and several other branches of physical sciences. Applications have ranged from geophysics, quantum dots to composites. Over the past two decades, due to an interest in all things “small”, attempts have been made to extend Eshelby's elastic analysis to the nanoscale by incorporating capillary or surface energy effects. In this note, we revisit a particular formulation that derives a very general expression for the elasto-capillary state of an embedded inclusion. This approach, that closely mimics that of Eshelby's original paper, appears to have the advantage that it can be readily used for inclusions of arbitrary shape (for numerical calculations) and provides a facile route for approximate solutions when closed-form expressions are not possible. Specifically, in the case of inclusions of constant curvature (sphere, cylinder) subject to some simplifications, closed-form expressions are obtained.

Characterization of Fuzzy δg*-Closed Sets in Fuzzy Topological Spaces

The purpose of this research article is to explain the meaning of g-closed sets in fuzzy topological spaces, which is more understandable to the readers and we find some of its basic properties. The concept of fuzzy sets was introduced by Zadeh in his classical paper (1965). Thereafter many investigations have been carried out, in the general theoretical field and also in different applied areas, based on this concept. The idea of fuzzy topological space was introduced by Chang (1968). The idea is more or less a generalization of ordinary topological spaces. Different aspects of such spaces have been developed, by several investigators. This paper is also devoted to the development of the theory of fuzzy topological spaces.
