Dimensional research on organization structure: meta-analysis and conceptual redirection

A previous meta-analysis of dimensional structure research published during the latter half of the 20th century revealed significant intercorrelation among structural dimensions inspired by Max Weber's bureaucratic ideal type, providing support for continued research on dimensional structures and for the bureaucratic structural model that served as its theoretical foundation. A new meta-analysis reported in this article, motivated by questions regarding the continued applicability of bureaucratic dimensional models in the later era of new organization forms, indicates that many of the interrelationships among five structural dimensions (formalization, standardization, specialization, vertical differentiation, and decentralization) have weakened since the time of the earlier meta-analysis. The results of this study, conducted using a sample of 346 correlations from a collection of 155 published articles, are interpreted as failing to provide consistent evidence supporting a central tenet of the bureaucratic structural model, therefore, as indicating that dimensional structural research now lacks a viable theoretical foundation.

EFL Teachers' Optimism and Commitment and Their Contribution to Students' Academic Success

The present review study determines to scrutinize EFL teachers' optimism and commitment and their contribution to students' academic success. Academic optimism, as a new construct, is evolving from the examination of the positive psychology (PP), societal principal, and communal school assets that affect the attainment and success of all learners. In addition, within the past decades, commitment has received a great level of consideration, principally in the domain of structural research. The straightforward perseverance of this review is to extend the concept of academic optimism to individuals, that is, to hypothesize theoretical optimism and approve the efficacy of this paradigm at the instructor level in relation to students' academic success. According to the literature review, the definitions of these constructs, namely teachers' optimism and commitment, and students' academic success, as well as empirical studies in this domain are presented. As a conclusion, this study, to some extent, promotes the educators' mindfulness about their commitment. In this respect, pedagogical implications for teachers, school principals, teacher-trainers, and future researchers are presented, and new guidelines for further research are determined.

Methodological basis of cognitive-anthropological semantics. The case of the Axiological Lexicon of Slavs and their Neighbours (vols. 1-5, 2015-2019)

The article consists of two parts. The first, methodological part presents the goal of cognitive-anthropological research in opposition to structural semantics and describes successive steps that lead to that goal. The second part contains commentary on the Axiological Lexicon of Slavs and their Neighbours, especially volume 5, devoted to honour. The aim of semantic-structural research is to reconstruct the semantic-lexical system of a language (as code) serving interpersonal communication – in other words, it is to reconstruct the information that one may obtain through the use of the code. The aim of cognitive-anthropological semantics is to reconstruct the conceptualization of linguistically salient fragments of reality.

Isotope-Labeled RNA Building Blocks for NMR Structure and Dynamics Studies

RNA structural research lags behind that of proteins, preventing a robust understanding of RNA functions. NMR spectroscopy is an apt technique for probing the structures and dynamics of RNA molecules in solution at atomic resolution. Still, RNA analysis by NMR suffers from spectral overlap and line broadening, both of which worsen for larger RNAs. Incorporation of stable isotope labels into RNA has provided several solutions to these challenges. In this review, we summarize the benefits and limitations of various methods used to obtain isotope-labeled RNA building blocks and how they are used to prepare isotope-labeled RNA for NMR structure and dynamics studies.

The Use of Structural Methodology in Postmodern Concepts of Technology

The article is aimed at defining the possibilities for structural methodology to understand the phenomenon of modern technology. Some principles of postmodernists’ structural research are highlighted. The embodiment of these principles in the analytical discourse is shown, considering the state and development of technical activities and how they allow one to assess and predict future events. These predictions about mechanization, informatization and virtualization of almost all areas of modern society are contemplated pessimistic by some thinkers and optimistic by others. The conducted study showed that the structural methodology is a fairly effective means of philosophical understanding of the phenomena of technical reality. More and more people become involved in technology, and it is generally not perceived as involved in global threats. Instead, the dynamics and the consequences of structural transformations in the technical field are deeply interpreted by philosophers, who formulate their predictions and thus signal the dangers to culture and civilization.

Multi-Genre Strategies of “Walking with Pushkin” by A. Terts (A. Sinyavsky)

Based on the material of the book “Walking with Pushkin” by Abram Terts (Andrey Sinyavsky), the goal is to determine the main narrative strategies that the writer implemented. The authors demonstrate that along with the genre definitions of “novel”, “novella”, “essay”, the narrative is mediated by the techniques of “philological prose” and scientific discourse. It is shown that markers of scientific discursively narrative SinyavskyTerts in “Walking with Pushkin” is the number of characteristic features: composite partitioning, the extension of the goals and objectives of the analysis, the coverage of the history of the problem, selection of research methodology, the definition of the novelty of the work, the establishment of perspectives, providing structural integrity, respect of chronology in understanding material, the use of the bibliographic apparatus, etc. According to the authors, the experience of Sinyavsky, a research scientist, who defended the dissertation at MSU, working in world literature of the Academy of Sciences of the USSR, who read lectures at Moscow state University and the Moscow art theatre Studio, influenced the nature of the material in the “Walking.” and served as canon of structural research. It is established that a “free” manner of presentation of scientific observations is expressive means of focusing attention on the most pressing issues of domestic scientists to update the relationship of history and modernity (his understanding of own creativity, manifestation of the principle of “pure art”, the semantics of the principle of freedom within the literature of socialist realism, etc.).

Environmental Behavior Spillover or Public Information Induction: Consumers’ Intention to Pay a Premium for Rice Grown with Green Manure as Crop Fertilizer

Nowadays, there is a growing interest in pro-environmental foods produced by pro-environmental practices. However, consumers’ payment motivations towards such foods are currently poorly understood. This manuscript provided a critical investigation of Chinese consumers’ intention to pay a premium (ITPP) for rice grown with green manure as crop fertilizer (GMR). One focus was the establishment of an explanatory structural research framework that includes effects of environmental behavior spillover (EBS) and public information induction (PII); another focus was to analyze the impacts of the selected structural elements on ITPP by introducing education as a moderator. Results suggest that consumers’ ITPP can be largely influenced by PII, therefore, for GMR marketers and policy makers, measures should be developed to widen consumers’ access to public information related to GMR and to improve their capacity of screening effective information. EBS, when ITPP remains low, emerged as a pivotal predictor of consumers’ ITPP. This observation provides us with the enlightenment that breeding consumers’ daily environmental behaviors is highly valued to inspire their payment intention in the early stages of GMR market development. Another finding is that, with the introduction of the educational variable, the influence coefficients of EBS and PII on ITPP increased from 0.42 and 0.53 to 0.61 and 0.66, respectively, which means that it is possible to boost consumers’ payment intention by improving their educational attainment. This study contributes to the existing literature by providing empirical evidence for the GMR industrial upgrading strategy and have significant implications for the environmental governance of the agricultural sector.

Mechanisms of Proteolytic Enzymes and Their Inhibition in QM/MM Studies

Experimental evidence for enzymatic mechanisms is often scarce, and in many cases inadvertently biased by the employed methods. Thus, apparently contradictory model mechanisms can result in decade long discussions about the correct interpretation of data and the true theory behind it. However, often such opposing views turn out to be special cases of a more comprehensive and superior concept. Molecular dynamics (MD) and the more advanced molecular mechanical and quantum mechanical approach (QM/MM) provide a relatively consistent framework to treat enzymatic mechanisms, in particular, the activity of proteolytic enzymes. In line with this, computational chemistry based on experimental structures came up with studies on all major protease classes in recent years; examples of aspartic, metallo-, cysteine, serine, and threonine protease mechanisms are well founded on corresponding standards. In addition, experimental evidence from enzyme kinetics, structural research, and various other methods supports the described calculated mechanisms. One step beyond is the application of this information to the design of new and powerful inhibitors of disease-related enzymes, such as the HIV protease. In this overview, a few examples demonstrate the high potential of the QM/MM approach for sophisticated pharmaceutical compound design and supporting functions in the analysis of biomolecular structures.
