The concept of environmental diplomacy appears associated with events (conventions) promoted between states and transnational organisations to discuss aspects related to regulating the use of natural resources and regulating pollution. In this study, the authors intend to highlight the contribution brought to environmental diplomacy by leading television figure David Attenborough and his focus on the destruction of biodiversity by humans (the problem). It is intended to analyse the frames of his public interventions, comparing them with the prevailing frames in the UNFCCC policies.

A predominantly inductive method of qualitative and interpretative nature is used. In epistemological terms, the framing analysis stems from a social constructivist perspective. A theoretical model for frame analysis was defined by combining the frameworks proposed by Entman (1993) and Semetko and Valkenburg (2000) and considering previous studies (Anholt, 2015; Seelig, 2019). Analysis scrutinised a two-fold corpus comprising articles regarding actions and statements by David Attenborough published in The Guardian between 2018 and 2020, and the UN's legal framework for climate change.

The most prominent frames regarding climate crisis in transnational policies are responsibilities. Attenborough's calls for action highlight the frames of “morality”, “responsibilities” and “problems”. However, it is necessary to make a distinction between the discourse used in transnational treaties and that by Attenborough. In the former, discourse is more technical and impersonal, presented in a structure of legal diplomas and barely accessible to the public. In contrast, Attenborough's speech is more emotional, appealing and sometimes dramatic. His message is transmitted straightforwardly to the public in a pedagogical, personal tone.

The choice of high-profile personalities like David Attenborough as ambassadors has implications in the visibility of the environmental cause, and in the multiplication of initiatives that denounce environmental degradation.

This study explores and analyses the narrative construct regarding climate change as carried out by a trusted and respected media voice. The authors intend to contribute to understanding the amplification role of public figures in controversial issues and diplomatic matters. The main contribution of this study is to highlight the strategic nature of the choice of SDA by political powers to voice the drama of climate emergency.

The vibration of the rails is a significant source of railway rolling noise, often forming the dominant component of noise in the important frequency region between 400 and 2000 Hz. The purpose of the paper is to investigate the influence of the ground profile and the presence of the train body on the sound radiation from the rail.

Two-dimensional boundary element calculations are used, in which the rail vibration is the source. The ground profile and various different shapes of train body are introduced in the model, and results are observed in terms of sound power and sound pressure. Comparisons are also made with vibro-acoustic measurements performed with and without a train present.

The sound radiated by the rail in the absence of the train body is strongly attenuated by shielding due to the ballast shoulder. When the train body is present, the sound from the vertical rail motion is reflected back down toward the track where it is partly absorbed by the ballast. Nevertheless, the sound pressure at the trackside is increased by typically 0–5 dB. For the lateral vibration of the rail, the effects are much smaller. Once the sound power is known, the sound pressure with the train present can be approximated reasonably well with simple line source directivities.

Numerical models used to predict the sound radiation from railway rails have generally neglected the influence of the ground profile and reflections from the underside of the train body on the sound power and directivity of the rail. These effects are studied in a systematic way including comparisons with measurements.

The objective of the chapter is to provide an integrative appraisal of recent participatory research projects with children on violence and maltreatment conducted by members of the COST Action CA 19106 working group on children's participation (WG3) and their colleagues to identify what is working well and what needs to change in future research. The evaluation of research examples clustered around four key questions: Why, when, how and how much do children participate in research? Data were collected using a unified tool designed to characterise participatory research, which was distributed among WG3 members. In addition, chapters of the current book were another source of data about participatory research. Overall, data on 19 studies involving 46,761 children were collected and analysed using Shier's matrix. Findings show that most studies (n = 10) engaged children as consultants to adults in data collection, whereas a few studies (n = 5) demonstrated a more children-led research approach. The analysis uncovered specific areas where more progress is required, including engaging children in decisions about the research topic, involving young children, utilising methods that are more natural and familiar to children, and gaining children's reflective accounts about their participation experience. The authors encourage scholars to publish their work to advance evidence-based knowledge and skills in participatory research with children about sensitive topics.

The purpose of this paper is to consider the economic information content within several popular stock market factors and to the extent to which their movements are both explained by economic variables and can explain future output growth.

Using US stock portfolios from 1964 to 2019, the authors undertake three related exercises: whether a set of common factors contain independent predictive ability for stock returns, what economic and market variables explain movements in the factors and whether stock market factors have predictive power for future output growth.

The results show that several of the considered factors do not contain independent information for stock returns. Further, most of these factors are neither explained by economic conditions nor they provide any predictive power for future output growth. Thus, they appear to contain very little economic content. However, the results suggest that the impact of these factors is more prominent with higher macroeconomic risk (contractionary regime).

The stock market factors are more likely to reflect existing market conditions and exhibit a weaker relation with economic conditions and do not act as a window on future behavior.

Fama and French three-factor model still have better explanations for stock returns and economic information more than any other models.

This paper contributes to the literature by examining whether a selection of factors provides unique information when modelling stock returns data. It also investigates what variables can predict movements in the stock market factors. Third, it examines whether the factors exhibit a link with subsequent economic output. This should establish whether the stock market factors contain useful information for stock returns and the macroeconomy or whether the significance of the factor is a result of chance. The results in this paper should advance our understanding of asset price movement and the links between the macroeconomy and financial markets and, thus, be of interest to academics, investors and policy-makers.
