Topic evolution helps the understanding of current research topics and their histories by automatically modeling and detecting the set of shared research fields in academic publications as topics. This paper provides a generalized analysis of the topic evolution method for predicting the emergence of new topics, which can operate on any dataset where the topics are defined as the relationships of their neighborhoods in the past by extrapolating to the future topics. Twenty sample topic networks were built with various fields-of-study keywords as seeds, covering domains such as business, materials, diseases, and computer science from the Microsoft Academic Graph dataset. The binary classifier was trained for each topic network using 15 structural features of emerging and existing topics and consistently resulted in accuracy and F1 over 0.91 for all twenty datasets over the periods of 2000 to 2019. Feature selection showed that the models retained most of the performance with only one-third of the tested features. Incremental learning was tested within the same topic over time and between different topics, which resulted in slight performance improvements in both cases. This indicates there is an underlying pattern to the neighbors of new topics common to research domains, likely beyond the sample topics used in the experiment. The result showed that network-based new topic prediction can be applied to various research domains with different research patterns.

The authors reflect on the dire state of motor learning at the time of Brooks’s book and consider reasons why research was resurrected in the 1980s and flourished in the ensuing years. In so doing, they provide an overview of the various research topics that have been studied, discuss the influence of motor learning on other fields of study, and consider the future of motor learning research both within and outside the academic study of kinesiology.

Various types of intermediate-sized (10-nm) filaments have been found and described in many different cell types during the past few years. Despite the differences in the chemical composition among the different types of filaments, they all yield common structural features: they are usually up to several microns long and have a diameter of 7 to 10 nm; there is evidence that they are made of several 2 to 3.5 nm wide protofilaments which are helically wound around each other; the secondary structure of the polypeptides constituting the filaments is rich in ∞-helix. However a detailed description of their structural organization is lacking to date.

Tourism and landscape are broad and complex scientific research fields, as is the synergy between them has given rise to a volume of articles diverse in nature, subject matter and methodology. These difficulties mean that, at present, there is no complete theoretical framework to support this tourism and landscape research, nor complete knowledge of its structure and organization. This motivates the present work, which constitutes the first attempt at mapping this research topic by applying bibliometric techniques using VOSviewer and Science Mapping Analysis Software Tool (SciMAT) software. A total of 3340 articles from journals indexed in Web of Science were analyzed. The results obtained confirm that interest in the study of these concepts has been growing, especially in the last decade. The main contribution of this work lies in the identification of work themes that were basic to the construction of the field but that are currently in decline, such as “cultural heritage” and other themes important to the field that should continue to be dealt with, such as “national parks” or “geotourism”. The transversal nature of sustainability that appears in the network of keywords related to currently emerging themes, such as “planning” and “environment”, is also highlighted and reinforced.

Sphingolipids are complex lipids widespread in nature as structural components of biomembranes. Commonly, the sphingolipids of marine organisms differ from those of terrestrial animals and plants. The gangliosides are the most complex sphingolipids characteristic of vertebrates that have been found in only the Echinodermata (echinoderms) phylum of invertebrates. Sphingolipids of the representatives of the Asteroidea and Holothuroidea classes are the most studied among all echinoderms. In this review, we have summarized the data on sphingolipids of these two classes of marine invertebrates over the past two decades. Recently established structures, properties, and peculiarities of biogenesis of ceramides, cerebrosides, and gangliosides from starfishes and holothurians are discussed. The purpose of this review is to provide the most complete information on the chemical structures, structural features, and biological activities of sphingolipids of the Asteroidea and Holothuroidea classes.

We consider the broad developments that have occurred over the past decade regarding our knowledge of how neighborhood context impacts intimate partner violence (IPV). Research has broadened the concept of “context” beyond structural features such as economic disadvantage, and extended into relationships among residents, collective “action” behaviors among residents, cultural and gender norms. Additionally, scholars have considered how the built environment might foster (or regulate) IPV. We now know more about the direct, indirect, and moderating ways that communities impact IPV. We encourage additional focus on the policy implications of the research findings.

AbstractIn the past two decades academic and research literature on “corruption” has flourished. During the same period organizations and initiatives fighting against corruption have also significantly expanded, turning “anti-corruption” into a new research subject. However, despite a few exceptions there is a division of labor between scholars who study corruption itself and those who study the global anti-corruption industry. Juxtaposing corruption’s local discourses and anti-corruption international practices, this article is an attempt to bring together these two intertwined research dimensions and explore how an ethnographic approach might contribute to framing them together. Firstly, it describes how corruption in Romania is often conceptualized and explained in terms of national heritage, something related to old and recent cultural history, including traditional folklore. Secondly, it explores how anti-corruption works in practice, focusing on international legal cooperation projects monitoring the progress and shortcomings both prior to and post Romania’s accession to the European Union. Finally, revealing the articulations of these two apparently unrelated research fields, the article argues that corruption’s local explanations and the circular logic of auditing observed within the anti-corruption industry share a common developmental ideology mirroring the crypto-colonialist structure of power relations and dependency among European nation-states emerging out of the Cold War.

This paper aims at providing an overview on the current state of the art and on possible future developments concerning the component method implementation for the classification of beam-to-column joints belonging to aluminum moment resisting frames.After a brief discussion on the component method theoretical bases, developed in the past to give a feasible calculation procedure for steel joints, recent experimental and numerical studies, carried out for investigating some aluminum components, are presented and discussed. In particular strengths and weaknesses of the current knowledge are put into evidence, also in light of the peculiarities that make aluminum alloys different from steel. The launch of new research fields, aimed at pursuing an update of the current codes dealing with aluminum structures, is therefore proposed.

Purpose – The purpose of this paper is to contribute to the ten years of the journal through a personal reflection. Design/methodology/approach – A review of the articles published in the last ten years. Findings – I argue that what has distinguished QROM in these ten years are two distinctive features: reflexivity on practices of qualitative research, and openness to the application of qualitative methods to unusual research topics. Originality/value – The main limit of the paper resides in the subjectivity of the person who has read the articles. Other readers may have different opinions and may have chosen different criteria.

Objectives We present a bibliometric review of research on trait mindfulness published from 2005 till 2021 to determine the current state of the field and identify research trajectories. Methods A search conducted on Jan 30, 2021 using the search terms “trait mindfulness” OR “dispositional mindfulness” in the Web of Science Core Collection identified 1,229 documents. Results Using keyword-based network analyses, the various clusters suggested two major approaches in the field, one focusing on cognitive attentional processes, and a second approach that encompasses a wider field of well-being and clinical research topics. We also increasing consolidation of research fields over time, with research on wider individual differences such as personality being subsumed into clinically and wellbeing-oriented research topics. More recently, a distinct theme focused on the validity of measurement of mindfulness emerged. In addition to general patterns in the field, we examined the global distribution of trait mindfulness research. Research output was substantially skewed towards North American-based researchers with less international collaborations. Chinese researchers nevertheless also produced research at significant rates. Comparing the difference in research topics between China and the US-based researchers we found substantial differences with US research emphasizing meditation and substance abuse issues, whereas researchers from China focused on methodological questions. Conclusions Overall, our review indicates that research on trait mindfulness might profit from conceptual and cultural realignment, with greater focus on individual differences research in other areas of psychology to complement the strong clinical and cognitive focus we well as also stronger cross-cultural and comparative studies.
