Intellectual Structure of the Belt and Road Initiative Research: A Scientometric Analysis and Suggestions for a Future Research Agenda

2020

China’s Belt and Road Initiative (BRI) has attracted increasing attention worldwide since its inception in 2013. Although the research is fast increasing in terms of publications, there is a lack of knowledge about the intellectual structure, research trends, and appropriate theories underpinning. Using bibliometric data from 1583 articles from 2013 to 2019 in the Web of Science and Scopus databases, we used bibliometric techniques and scientometric analyses to identify and analyze the intellectual structure, hotspots, and emerging trends in this field. We identified 18 clusters that we categorized into three groups for thematic discussion. Research gaps and future research directions were …

State-feedback sampled-data control design for nonlinear systems via passive theory

2013

Published version of an article in the journal: Mathematical Problems in Engineering. Also available from the publisher at: http://dx.doi.org/10.1155/2013/230413 Open Access This paper investigates the problem of passive controller design for a class of nonlinear systems under variable sampling. The Takagi-Sugeno (T-S) fuzzy modeling method is utilized to represent the nonlinear systems. Attention is focused on the design of passive controller for the T-S fuzzy systems via sampled-data control approach. Under the concept of very-strict passivity, a novel time-dependent Lyapunov functional is constructed to develop passive analysis criteria and passive controller synthesis conditions. A new …

On the asymptotic behavior of solutions to a class of third-order nonlinear neutral differential equations

2020

Abstract By using comparison principles, we analyze the asymptotic behavior of solutions to a class of third-order nonlinear neutral differential equations. Due to less restrictive assumptions on the coefficients of the equation and on the deviating argument τ , our criteria improve a number of related results reported in the literature.

Genomic reaction norms inform predictions of plastic and adaptive responses to climate change

2022

Genomic reaction norms represent the range of gene expression phenotypes (usually mRNA transcript levels) expressed by a genotype along an environmental gradient. Reaction norms derived from common-garden experiments are powerful approaches for disentangling plastic and adaptive responses to environmental change in natural populations. By treating gene expression as a phenotype in itself, genomic reaction norms represent invaluable tools for exploring causal mechanisms underlying organismal responses to climate change across multiple levels of biodiversity. Our goal is to provide the context, framework and motivation for applying genomic reaction norms to study the responses of natural popu…

Teachers’ responses to children in emotional distress: A study of co-regulation in the first year of primary school in Norway

2020

The purpose of this study was to explore how first-grade teachers respond to pupils in emotional distress within the framework of co-regulation. Co-regulation in this context refers to an adult–chi...

Helping children in bullying situations: The role of intersubjective understanding and co-regulation

2020

Contemporary definitions of bullying are strikingly in agreement that bullying represents aggressive behaviour involving premeditation, time span, power imbalance and clear role assignment. Even though useful in some situations, these premises are not as helpful if the aim is to improve the social environment in educational contexts. The aim of the present article is to argue that educators need alternative theoretical tools when attempting to improve relations between children. We argue that interpretations of bullying in educational contexts are not ‘owned’ by any specific party, but rather involve (1) intersubjective negotiation and (2) the co-regulative competence of educators and child…

A commentary on the Special Issue “Innovations in measuring and fostering mathematical modelling competencies”

2021

This is a commentary on the ESM 2021 Special Issue on Innovations in Measuring and Fostering Mathematical Modelling Competencies. We have grouped the ten studies into three themes: competencies, fostering, and measuring. The first theme and the papers therein provide a platform to discuss the cognitivist backgrounds to the different conceptualizations of mathematical modelling competencies, based on the modelling cycle. We suggest theoretical widening through a competence continuum and enriching of the modelling cycle with overarching, analytic dimensions for creativity, tool use, metacognition, and so forth. The second theme and the papers therein showcase innovative ideas on fostering an…

The genre repertoires of Norwegian beauty and lifestyle influencers on YouTube

2021

Abstract YouTube represents an increasingly popular cultural phenomenon in the contemporary Norwegian media landscape. Since the inception of the digital video platform over 15 years ago, personal videoblogging has emerged as one of its dominant types of user-generated content. In this article, I draw from New Rhetoric genre theory and netnographic approaches to explore the beauty and lifestyle sphere on YouTube, in which several emergent genres are situated within a new media ecosystem. Through a qualitative content analysis of seven established Norwegian YouTube channels, a total of 17 individual genres were identified. Furthermore, I elaborate upon how informational, instructional, and c…

Dignity, Dependence, and Relational Autonomy for Older People Living in Nursing Homes

2015

Dignity is a core concept in nursing care. In earlier theories on dignity, close links have been drawn between dignity and autonomy, and autonomy has been closely related to independence. These traditional understandings of dignity and autonomy may be challenged when an individual moves into a nursing home. Our findings show that negative views about dependence, institutional frames and structures in the nursing home, and the attitudes and actions of healthcare personnel may diminish independence and lead to a lack of autonomy. Each of these areas can be experienced as a serious threat to the residents' dignity. Findings are interpreted and discussed in the light of a theory of relational a…
