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.

In the era of digital disruption and customer loyalty loss, it has become even more important to shape the experience journey of a firm’s stakeholders. The benefits of experience data (XD) analysis for a competitive advantage and firm performance are well proven in the business-to-customer context. Therefore, this study aims to explore the limited exploitation of XD in the business-to-business (B2B) context.

The data of 338 B2B firms is generated through computer-assisted telephone interviewing using a structured interview guideline. A Mann–Whitney U test and binary linear regression are applied to test hypotheses derived from literature.

The results suggest that XD non-collectors see XD increase efficiency, whereas XD collectors view XD strategically beyond customer data. Additionally, the successful application of XD in firms can be fostered by connecting XD with operational data through digitalised processes, strategic usage and data collection at certain defined points of time.

This study contributes to the understanding of XD perception between collectors and non-collectors and develops determinants for the successful application of XD management. Based on the results, B2B marketing executives from academics and practice can foster the implementation of XD management to improve all firm’s stakeholders’ experiences. In this way, this study contributes to the understanding of managing not only customers’ but other stakeholders’ experiences.

The purpose of this paper is to analyze the impact of the coronavirus (COVID-19) pandemic on participation and time allocated to work from home (WFH) by ethnic/racial group.

The authors employ USA time-use data [American Time Use Survey (ATUS)] for the 2017–2020 period and a parametric approach in their analysis.

Estimates show that the time allocated to WFH increased during COVID-19, especially for women. This increase is likely driven by more workers shifting to WFH (higher participation) rather than by longer hours worked by those who already teleworked. The authors also find relevant differences in the impact of COVID-19 on WFH by ethnic/racial group. Among ethnic/racial groups, only Asians increased WFH compared to White Americans. Within this ethnic group, the authors find significant differences across genders. Asian men increased participation in WFH, whereas Asian women increased both participation and hours worked, compared to White American women. Differences in this racial/ethnic group could be explained by previous research, which demonstrates a higher ability of Asians to perform job tasks remotely. However, this finding could also be attributed to an increase in discrimination during the COVID-19 pandemic.

This paper contributes to the recent and limited literature exploring the heterogeneous impact of COVID-19 on participation and time allocated to WFH by ethnic/racial group. Understanding the mechanisms driving vulnerable populations' abilities to work during socioeconomic downturns is of high policy importance.

Overcrowding continues to afflict emergency departments (EDs), and its attendant consequences are becoming increasingly severe. The burden of the COVID-19 pandemic is further escalating the situation worldwide. One of the most critical questions is how to adequately quantify what constitutes overcrowding and determine implications for operations management in improving service efficiency. This paper aims to discuss the aforementioned.

The authors propose the time and class complexity measures for ED service systems, taking into account important patient-level and system characteristics. Using an extensive data set from a Canadian ED, the authors investigate the performance of complexity-based measures in predicting service delays.

The authors find that the complexity measure is potentially more important than some well-known crowding metrics. In particular, EDs can improve service efficiency by managing the level of complexity within a desirable interval. Furthermore, complexity exposes how the interplay between demand-side behavioral changes and supply-side responses affects operational performance. Moreover, the results suggest that arrival patterns—the number of patients of each class arriving per time and times between events (arrivals and service completions)—increase the risk of service delays more than the demand volume.

This paper is the first to provide an extensive investigation into the application of the complexity-based measure for ED crowding. The study demonstrates potential values to be gained in ED service systems if complexity measure is incorporated into their operations management decisions.

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.

This paper addresses a significant research gap in the study of Rayleigh surface wave propagation within a piezoelectric medium characterized by piezoelectric properties, thermal effects and voids. Previous research has often overlooked the crucial aspects related to voids. This study aims to provide analytical solutions for Rayleigh waves propagating through a medium consisting of a nonlocal piezo-thermo-elastic material with voids under the Moore–Gibson–Thompson thermo-elasticity theory with memory dependencies.

The analytical solutions are derived using a wave-mode method, and roots are computed from the characteristic equation using the Durand–Kerner method. These roots are then filtered based on the decay condition of surface waves. The analysis pertains to a medium subjected to stress-free and isothermal boundary conditions.

Computational simulations are performed to determine the attenuation coefficient and phase velocity of Rayleigh waves. This investigation goes beyond mere calculations and examines particle motion to gain deeper insights into Rayleigh wave propagation. Furthermore, this investigates how kernel function and nonlocal parameters influence these wave phenomena.

The results of this study reveal several unique cases that significantly contribute to the understanding of Rayleigh wave propagation within this intricate material system, particularly in the presence of voids.

This investigation provides valuable insights into the synergistic dynamics among piezoelectric constituents, void structures and Rayleigh wave propagation, enabling advancements in sensor technology, augmented energy harvesting methodologies and pioneering seismic monitoring approaches.

This study formulates a novel governing equation for a nonlocal piezo-thermo-elastic medium with voids, highlighting the significance of Rayleigh waves and investigating the impact of memory.

Post-Sarbanes Oxley Act (SOX), the audit committee has been empowered greatly to play a central role in the corporate governance of firms. Embedded in agency theory, this study aims to examine the effect of the audit committee on the likelihood by firms to pay dividends.

The study population is US firms in the Institutional Shareholder Services (ISS) database from 2007 to 2018. The authors apply the multivariate logit fixed-effect regression for the analyses after conducting the appropriate statistical tests.

From the results of the research model, the authors find that there is a positive relationship between the size and gender diversity of the audit committee and the propensity to pay dividends suggesting that a larger audit committee with substantial women representation improve the information environment in firms leading to higher dividend distribution. The extent of busyness of the audit committee impacts negatively on the propensity to pay dividends. The results are driven by high-performing firms and not driven by specific levels of firm size.

The findings of the study give impetus to the audit committee as an important component of the corporate governance mechanism that advances the interest of stakeholders. Thus, efforts that seeks to promote the audit committee’s resourcefulness must be embraced by all stakeholders.

To the best of the authors’ knowledge, this study is the first to focus on audit committee and dividend payout policy of US firms post-SOX. The study demonstrates how the audit committee characteristics including its size, gender diversity and busyness affect dividend policy by mitigating information asymmetry problems.

The study aims to highlight and understand, and bring the human agency into the debate on the theory of normative control. While, the previous literature has highlighted the problem of the missing subject. However, the actual human agency in terms of agential properties has not been seriously addressed. This study is an attempt to overcome this problem of the missing subject.

A two-phase design inspired by retroductive inference was adopted for this study. In the first phase, abduction was used to explore the literature on normative control to highlight the forces of attraction, which may pull the employees to participate willingly within normative control systems. In the second phase, following retroductive inference, agential explanations of the forces of attraction identified in the first phase were explored by venturing into other related fields, e.g. psychology and sociology.

The study highlights four strategies used by organizations using normative control, i.e. comfort zoning, relational bonding, moral trapping and elitist appeal. These strategies rely on attractive forces. These forces of attraction pull employees to participate in the normative control system. The attractive element in the identified strategies is due to the fact that these strategies target specific agential properties, i.e. the need for comfort, sense of belonging, moral agency and pride. Overall, the findings suggest that individuals drive their concerns from culture but in relation to their capacity as needy beings for being enculturated.

Theoretically, this study adds conceptual strength to the explanations of normative control. It is suggested that neglect of human agency renders explanations conceptually weak. The study fills this gap in the research. Practically, this study would be beneficial for better design and implementation of normative control. Several studies have pointed out that normative control does not yield the intended results. Out of many reasons, a lack of understanding of human agency is a major cause of unsuccessful attempts to normatively control employees. This study provides some basis to understand the human subject for better design of soft systems of control.

To the best of the authors’ knowledge, this is the first research study that explores agential properties with reference to normative control systems. This study is important for researchers and practitioners.

This article aims to explore the potential of feminist phenomenology as a conceptual framework for advancing women’s entrepreneurship research and the suitability of interpretative phenomenological analysis (IPA) to the proposed framework.

The article critically examines the current state of women’s entrepreneurship research regarding the institutional context and highlights the benefits of a shift towards feminist phenomenology.

The prevailing disembodied and gender-neutral portrayal of entrepreneurship has resulted in an equivocal understanding of women’s entrepreneurship and perpetuated a male-biased discourse within research and practice. By adopting a feminist phenomenological approach, this article argues for the importance of considering the ontological dimensions of lived experiences of situatedness, intersubjectivity, intentionality and temporality in analysing women entrepreneurs’ agency within gendered institutional contexts. It also demonstrates that feminist phenomenology could broaden the current scope of IPA regarding the embodied dimension of language.

The adoption of feminist phenomenology and IPA presents new avenues for research that go beyond the traditional cognitive approach in entrepreneurship, contributing to theory and practice. The proposed conceptual framework also has some limitations that provide opportunities for future research, such as a phenomenological intersectional approach and arts-based methods.

The article contributes to a new research agenda in women’s entrepreneurship research by offering a feminist phenomenological framework that focuses on the embodied dimension of entrepreneurship through the integration of IPA and conceptual metaphor theory (CMT).

This study aims to investigate consumers’ construction of food localness through the politics of belonging in a regional context.

Following a socio-spatial lens and considering the “realm of meaning” of place, this research focusses on local consumers’ lived meanings of “local” food choice, and hence adopts a phenomenological approach to the data collection and analysis of 20 in-depth interviews with residents of the Italian region of Marche.

Drawing on Trudeau’s (2006) politics of belonging, this study reveals three interconnected themes which show how local consumers articulate a local food “orthodoxy” and how their discourses and practices draw and maintain a boundary between local and non-local food, whereby local food is considered “autochthonous” of rural space. Thus, this study’s participants construct a local food landscape, conveying rural (vs urban) meanings through which food acquires “localness” (vs non-“localness”) status.

There exists further theoretical opportunity to consider local consumers’ construction of food localness through the politics of belonging in terms of non-representational theory (Thrift, 2008), to help reveal added nuances to the construction of food localness as well as to the complex process of formulating place meaning.

The findings provide considerable scope for food producers, manufacturers and/or marketers to differentiate local food products by enhancing consumers’ direct experience of it in relation to rural space. Thus, enabling local food producers to convey rural (vs urban) meanings to consumers, who would develop an orthodoxy guiding future choice.

The findings enable regional promoters and food policymakers to leverage the symbolic distinctiveness of food autochthony to promote place and encourage consumers to participate in their local food system.

By using the politics of belonging as an analytical framework, this study shows that the urban–rural dichotomy – rather than being an obsolete epistemological category – fuels politics of belonging dynamics, and that local food consumers socially construct food localness not merely as a romanticisation of rurality but as a territorial expression of the contemporary local/non-local cultural conflict implied in the politics of belonging. Thus, this study advances our theoretical understanding by demonstrating that food “becomes” local and therefore, builds on extant food localness conceptualisations.
