The purpose of this study is to compare violent and non-violent extremists in terms of their age when they first perpetrate an extremist act, and to understand how this relates to other factors underlying extremist behaviours. While the end goal of many extremists may be functionally similar, the pathways into extremism vary, and the literature has demonstrated that a “one-size-fits-all” explanation does not exist. Motivational drivers are complex and dynamic; therefore, attempting to identify a terrorist “profile” has limited applied efficacy.

This study applied a temporal approach (“crime script analysis” or CSA) to identify, map and compare the sequential stages (or “scenes”) in the life histories of violent and non-violent extremists who have committed acts of extremism across different age groups. Crime scripts comprising mainly qualitative data for 40 male extremists (20 violent, 20 non-violent “cases”) were developed, and CSA was conducted according to the age at which they committed their first extremist offence.

Results demonstrated key temporal, developmental differences between the pathways of extremists who commit their first offence at different ages. One key difference was that for both the violent and non-violent extremists, those under 30 used the internet as a main means of joining networks and spreading information, whereas the over 30s made more personal, community links.

This research can aid identification of potential environmental triggers and potential increased susceptibility to triggers across certain age groups.

Helicopter fuselage vibration prediction is important to keep a safety and comfortable flight process. The helicopter vibration mechanism model is difficult to meet of demand for accurate vibration prediction. Thus, the purpose of this paper is to develop an intelligent algorithm for accurate helicopter fuselage vibration analysis.

In this research, a novel weighted variational mode decomposition (VMD)- extreme gradient boosting (xgboost) helicopter fuselage vibration prediction model is proposed. The vibration data is decomposed and reconstructed by the signal clustering results. The vibration response is predicted by xgboost algorithm based on the reconstructed data. The information transfer order between the controllable flight data and flight attitude are analyzed.

The mean absolute percentage error (MAPE), root mean square error (RMSE) and mean absolute error (MAE) of the proposed weighted VMD-xgboost model are decreased by 6.8%, 31.5% and 32.8% compared with xgboost model. The established weighted VMD-xgboost model has the highest prediction accuracy with the lowest mean MAPE, RMSE and MAE of 4.54%, 0.0162, and 0.0131, respectively. The attitude of horizontal tail and cycle pitch are the key factors to vibration.

A novel weighted VMD-xgboost intelligent prediction methods is proposed. The prediction effect of xgboost model is highly improved by using the signal-weighted reconstruction technique. In addition, the data set used is collected from actual helicopter flight process.

Estimation of solar cell parameters, mathematical modeling and the actual performance analysis of photovoltaic (PV) cells at various ecological conditions are very important in the design and analysis of maximum power point trackers and power converters. This study aims to propose the analysis and modeling of a simplified three-diode model based on the manufacturer’s performance data.

A novel technique is presented to evaluate the PV cell constraints and simplify the existing equation using analytical and iterative methods. To examine the current equation, this study focuses on three crucial operational points: open circuit, short circuit and maximum operating points. The number of parameters needed to estimate these built-in models is decreased from nine to five by an effective iteration method, considerably reducing computational requirements.

The proposed model, in contrast to the previous complex nine-parameter three-diode model, simplifies the modeling and analysis process by requiring only five parameters. To ensure the reliability and accuracy of this proposed model, its results were carefully compared with datasheet values under standard test conditions (STC). This model was implemented using MATLAB/Simulink and validated using a polycrystalline solar cell under STC conditions.

The proposed three-diode model clearly outperforms the earlier existing two-diode model in terms of accuracy and performance, especially in lower irradiance settings, according to the results and comparison analysis.

In the last two decades, risk reporting has followed a normative and calculative culture rather than the “materiality” of data. Although integrated reporting (IR) has become flooded with extra information, it does not adequately disseminate material information to stakeholders. In addition, the poor tone from the top diminishes creativity. This study aims to investigate how companies creatively address issues of the materiality of risk information in IR and how IR can be aligned with enterprise risk management.

Qualitative research was conducted via interviews with 50 chief risk officers and senior management executives in the Indian and UK insurance markets.

Overall, five institutions were observed to exhibit elements of being early adopters of institutional creativity. This confirmed the present study’s theoretical contribution of five divergent types of early adopters. The motivations for creativity are reflected in the resources available to these institutions.

To the best of the authors’ knowledge, this study provides a new insight into IR from internal mechanisms to deal with issue of materiality.

Through research on child sexual abuse (CSA) and adult survivors, knowledge is gained. This knowledge might support decisions – whether political, professional or otherwise – that affect the lives of children who are victims of CSA and adult survivors. Additionally, this knowledge influences what the public knows about CSA and adult survivors and as a consequence, how child victims of CSA and adult survivors are treated in everyday life. Given the huge impact research can have on survivors' lives, this chapter raises the question of what aspects of CSA and survivorship are relevant for survivors from survivors' perspective and whether these aspects can be addressed by Participatory Action Research (PAR) as a research paradigm. To identify relevant aspects, survivors' artwork is analysed because art is a way to contribute to public discourses with very little regulation. For analysis, the Sociology of Knowledge Approach to Discourse is used. In this chapter, we introduce basic theories of knowledge from a constructivist perspective in a short background section and explain the aim and method of analysis. Afterwards, we present some key aspects of survivors' art on CSA and survivorship: The invasiveness of CSA, speech, the symbolic violence behind physical abuse and issues of injustice and responsibility are discussed. Additionally, the discursive relation between artists and audience is of interest to finally answer whether – and, if so, why – PAR is an appropriate research paradigm to address these aspects.

Employing cognitive dissonance theory, this study examines how consumers’ preexisting attitudes toward an issue, value involvement with the issue and consumer-company identification (CCI) influence their reactions to corporate social advocacy (CSA) through cognitive dissonance.

Study 1 conducted a 2 (CSA position: pro vs anti) × 3 (preexisting issue attitude: pro vs neutral vs anti) online quasi-experiment. The CSA messages were created in the context of same-sex marriage(s). Study 2 tested the hypotheses using an online survey in the context of gun control.

The results indicated that a conflict between consumers’ preexisting attitudes and a corporation’s stance on a controversial issue led to cognitive dissonance, which further led to consumers’ perceptions of the corporation being biased in both studies. Study 1 and Study 2 suggested a mixed effect of cognitive dissonance on participants’ inclination to disidentify with the corporation. Preexisting CCI appeared to have a direct negative influence on cognitive dissonance; however, value involvement and preexisting CCI were not found to significantly enhance the influence of consumers’ attitudes toward CSA on cognitive dissonance.

The study first extended the theoretical discussion of cognitive dissonance to a trendy strategic communication context. The results help public relations practitioners to better understand the segmented public groups and the risk of taking a stance on controversial issues.

This study aims to examine the role of different forms of corporate social advocacy (CSA) in shaping individuals’ attitudinal and behavioral intentions towards companies taking their public stand on controversial socio-political issues. With an online experiment as the research method, this study tests whether depicting nonpolitical or political behaviors in CSA messages increases individuals’ positive behavioral intentions.

This study uses a single factor between subject online experiment. A total of 135 US young adults were recruited through a Qualtrics online panel. Three social media mockups were created to manipulate three levels of actions in CSA messages (no action, nonpolitical action and political action). Participants viewed one of those social media posts depicting presented actions to counter anti-LGBTQ + legislation in the USA and answered questions about values-driven motives behind CSA, brand preference and positive word-of-mouth (WOM) intention.

Participants displayed higher levels of brand preference when they viewed CSA messages depicting the company’s political action intended to repel anti-LGBTQ + legislation. Participants showed more positive WOM intentions towards the company when they perceived its political actions as more values-driven.

The findings of this study offer practical insights to companies when designing CSA messages and strategies. The results of this study indicate that the presence of political actions in CSA communication increases individuals’ positive behaviors towards companies. The results also suggest that depicting altruistic motives behind CSA leads individuals to talk about companies more in positive ways.

This study is one of the early studies investigating the impact of various forms of CSA on individuals’ attitudinal and behavioral intentions to companies practicing CSA. This study provides practical implications on how to effectively appeal individuals’ favorable attitudes and behaviors towards CSA. In particular, this research presents the importance of action aspects in individuals’ attitudes toward corporations’ CSA messages.

The process of knowledge production is usually assigned to scientists who use specific methods to extract knowledge from someone else's experience. Usually this includes collecting, aggregating and interpreting data from an uninvolved point of view; that is, from the outside. This procedure is supposed to guarantee objectivity and generalisation. Many child sexual abuse (CSA) survivors reject such an approach that turns them into objects again. This presents a problem for research because it limits the number and contribution of potential participants and can lead to bias. In self-help groups of CSA survivors, an enormous amount of experiential knowledge accumulates, and sometimes this is transferred into more than only individually valid knowledge. Based on this experience and aiming for more agency of CSA Survivors, a group of adult survivors and researchers developed a new approach to research. It focuses on the development of self-organised research, which enables survivors of sexualised violence to practice research without losing agency. They are indispensable and elementary parts in all phases of the process. This chapter shows one way of formalising this process so quality criteria can be developed and applied. Following the presented approach, evaluation of the presented methods is the appropriate next step because self-help groups give reason to estimate significant outcomes. These outcomes not only enable self-help groups of CSA survivors to incorporate new methods but also include the chance to empower adults, children or youth who have been victims of sexualised violence.

Using coconut shell aggregates (CSA) in concrete benefits agricultural waste management and reduces the demand for mineral resources. Several studies have found that concrete containing CSA can achieve strengths that are comparable to regular concrete. The purpose of the present work is to evaluate the concrete’s durability-related properties to supplement these earlier findings.

Cylindrical specimens were prepared with a constant water–cement ratio of 0.50 and CSA content ranging from 0% to 50% (at 10% increment) by volume of the total coarse aggregates. The specimens were cured for 28 days and then tested for density, surface hardness, electrical resistivity and water sorptivity. The surface hardness was measured to describe the concrete resistance to surface wearing, while the resistivity and sorptivity were evaluated to describe the material’s resistance to fluid penetration.

The results showed that the surface hardness of concrete remained on average at 325 Leeb and did not change significantly with CSA addition. The distribution of surface hardness was also similar across all CSA groups, with the interquartile range averaging 59 Leeb. These results suggest that the cement paste and gravel stiffness had a more pronounced influence on the surface hardness than CSA. On the other hand, concrete became lighter by about 9%, had lower resistivity by 80% and had significantly higher initial sorptivity by up to 110%, when 50% of its natural gravel was replaced with CSA. Future work may be done to improve the durability of CSA when used as coarse aggregate.

The present study is the first to show the lack of correlation between CSA content and surface hardness. It would mean that the surface hardness test may not completely capture the porous nature of CSA-added concrete. The paper concludes that without additional treatment prior to mixing, CSA may be limited only to applications where concrete is not in constant contact with water or deleterious substances.

Corporations are confronted with growing demands to take a stand on socio-political issues, i.e. corporate social advocacy (CSA), which affects their reputation in the public. Companies use different CSA message strategies, including calling the public to support and act on the issue they advocate. Using reactance theory, the authors investigate the impact of CSA messages with a call to action on corporate reputation in the case of a company's gender equality initiative.

A one-factorial (CSA message with or without a call to action) between-subjects experiment was conducted by surveying 172 individuals living in Switzerland. The CSA messages were created in the context of gender equality.

The authors' study indicates that CSA messages with a call to action compared to those without overall harmed corporate reputation due to individuals' reactance, which is higher for CSA messages with a call to action, negatively affecting corporate reputation. The impact of the CSA message strategy with a call to action on corporate reputation remains significant after controlling for issue alignment and political leaning.

Communicating about socio-political issues, especially taking a stand, is a significant challenge for corporations in an increasingly polarized society and has often led to backlash, boycotts and damage to corporate reputation. This study shows that the possible adverse effects of advocating for socio-political issues can be related to reactance. It emphasizes that companies advocating for contested issues must be more cautious about the message strategy than the issue itself.
