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.

Despite the gains that have been made by adopting contemporary theories of practice in entrepreneurship studies, the field still lacks a comprehensive practice theory of entrepreneurial learning. In this article, we develop a practice theory of entrepreneurial learning by elaborating on the relations between practicing, knowing and learning.

Using a video ethnography of a two-day “Startup Weekend for Refugees” event in Amsterdam, our aim is to further theorise the relational, material and embodied nature of entrepreneurial learning through analysing video fragments of naturally occurring practices.

Our findings demonstrate that entrepreneurial learning transpires through, and is emergent from, practices and their relations. On the one hand, practitioners learn to competently participate in various practices by sensing, observing and experimenting with the meaning of others' gestures and utterances. On the other, the learning of new opportunities for value creation emerges as practitioners connect various practices to one another through translation.

This article contributes by illustrating and explaining real-time instances of learning to develop a practice theory of entrepreneurial learning. This contributes to the literature by detailing the relations between learning, knowing and practising entrepreneurship, which leads to a novel alternative to existing individual- and organisational-level learning theories.

This study aims to understand how marketing faculty become reference-educators of business executives by exploring the factors that contribute to their teaching performance.

Exploratory qualitative research, using in-depth interviews in which the object of the study was the marketing educator, based on three Brazilian business schools.

The teaching performance depends on the teaching practice, which is influenced by technical knowledge, pedagogical factors and personal features. The development of a practitioner-educator is a complex process that arises from both formal and informal learning.

Deepens the understanding of marketing educators’ individual factors, proposing a model to expand the knowledge of the factors shaping a reference-educator.

Raises awareness among managers of Higher Education institutions of the relevance of the development of its educators considering not only pedagogical skills but also marketing and social skills.

Improvements in education generate a positive contribution to society. Better marketing educators may result in better professionals, which could, ultimately, generate more benefits both for corporations and for society.

Existing literature has neglected the understanding of how marketing educators’ individual factors may impact on good teaching to create a well-rounded practitioner-educator. This study seeks to address that gap by exploring how marketing faculty, especially practitioners of marketing, become reference-educators, that is, educators identified as exemplars of good practice by their students and peers.

To review the literature and identify research gaps in the role and influence boards of directors of companies have in occupational health and safety (OHS).

This was done in a scoping review built on a structured search in MEDLINE (PubMed), EMBASE, PsycINFO, Sociological Abstracts, CCInfoWeb, EconLit, Web of Science, CINAHL and gray literature. Citations and reference lists were tracked. Inclusion criteria were publication in English. Exclusion criteria were studies covering companies using subcontractors to arrange OHS, or with <250 employees.

Forty-nine studies were included. The majority contained empirical data (n = 28; 57%), some were entirely normative (n = 16; 33%), and a few contained normative claims far beyond empirical data (n = 5; 10%). Empirical studies gave no insight into the scope of impact of board activities on OHS, and no studies assess the causal mechanisms by which board activities influence OHS outcomes. Most studies focused on both health and safety (n = 20; 41%) or only safety (n = 15; 31%). Context might explain the focus on safety rather than health, but is not clearly elucidated by the studies. Several studies are describing leadership behavior, although not framed as such. A narrative summary is presented to facilitate future research.

Future research should include: (1) which board activities influence OHS, (2) how board activities influence OHS, (3) the influence of context and (4) the leadership role of boards of directors.

This study identifies a total lack of research on the basic mechanics of the relationship between boards and OHS.

The purpose of this paper is to retrace past developments that occurred in the Alaskan and Canadian North as of result of the Second World War and illustrate the ramifications of these events in the Canadian and American political landscapes as it pertains to warfare tourism. The paper also intends to initiate a discussion on how certain narratives pertaining to warfare tourism are promoted, while others are overlooked.

This paper analyses the political, economic, socio-cultural and technological factors that resulted in tourism growth or the lack thereof in the Canadian and American Norths.

Warfare tourism, like most types of tourism, is expected to grow. Through this growth comes opportunities to expand and integrate the discussion pertaining to warfare tourism in the Canadian and American Norths while also providing a starting point for discussion about potential solutions to address warfare tourism and cultural dissonance.

This viewpoint is dependent on literature reviews.

The relationship between Indigenous peoples and other marginalized populations in the Second World War and warfare tourism is a relatively new research area. For warfare tourism to become integrated into tourism policies and developments, a willingness to address cultural dissonance and integrate populations formerly marginalized in the Second World War will be required. This paper examines how northern and other marginalized voices can be integrated in future commemoration and interpretation strategies.

The paper provides an opportunity to examine the growth and healing that can result from warfare tourism.

This interdisciplinary collaboration conducted by a military historian, a northern historian and a tourism research researcher provides one of the first examinations of the impacts of the Second World War in North America, and the relevance of these impacts to the interpretation of warfare tourism in Canada.

International student enrollment in the U.S. higher education system has recently experienced profound growth. This research examines leadership-oriented differencesbetween international and domestic students and focuses on their growth in capacity associated with participation in co-curricular leadership programs. Similarly-sized gains emerged after participation, suggesting that these leadership programs create equal growth effects across both groups. However, the factors that predicted international students’ increases in leadership skill were different than their domestic peers, suggesting that developing effective leaders among college students across national background is a non-uniform, complexprocess. Recommendations include the suggestion for partnerships between international student scholar units and leadership educators, specialized workshops for international students, and creating nuanced curricula based on the various pathways that students take to becoming an effective leader.

The scarcity of women in advertising creative departments has been reported globally, particularly in creative managerial roles. This study goes a step beyond this evidence since this paper aims to test whether having at least one token woman in creative managerial positions (token+) may be associated with a larger presence of females in low-level creative jobs compared to creative departments led only by male creative managers.

A content analysis of the credit forms of 839 Spanish campaigns released in 2019 was conducted to determine the gender composition of 116 creative departments with more than three professionals.

Generalized Poisson Regressions indicated that when at least a token woman is present in a creative management role within agency networks, the number of females in low-level positions doubles with respect to creative departments led only by male managers. This relation was not found for independent agencies, though. The results are discussed under the lens of critical mass theory, attraction paradigm and homophily theory.

To the best of the authors’ knowledge, it is the first time in the literature that the relation among the number of token+ advertising female creative managers and the amount of females in lower-level creative positions is tested. This research is also original because the sample is from a non-Anglo-Saxon country. Moreover, the use of the Generalized Poisson Regressions technique is another novelty of this paper.

A perceived misalignment between socially responsible fans and football club management has recently led to a major crisis during the annual meeting in 2021 of Bayern Munich, one of the largest professional football teams in Europe. In an unprecedented scenario, Bayern Munich fans demanded that management drop one of its largest sponsors due to alleged violation of human rights. The goal of this paper is to examine this particular phenomenon, as it not only demonstrates a discrepancy between the social organizational identity and its image, but more importantly, how it impacts legitimation strategies and the fans' loyalty attitudes towards the club.

Using the underlying concepts of legitimacy and loyalty, this conceptual model paper proposes two frameworks for social responsibility in professional football clubs: (1) analyzing how the (mis-)alignment between organizational identity and image impacts fan loyalty and (2) depicting four different types of social responsibility strategies to align organizational identity and image.

The authors identify various theoretical concepts that influence organizational identity and image in and for social responsibility and combine the two critical concepts of legitimacy and loyalty to categorize the social responsibility strategies for professional football clubs.

Both frameworks advance the understanding of the decision-making behind social responsibility strategies and also synthesize the current literature to offer conceptual clarity regarding the varied implications and outcomes linked to the misalignment between organizational identity and image.

International student enrollment has experienced dramatic increases on U.S. campuses. Using a national dataset, the study explores and compares international and domestic students’ incoming and post-training levels of motivation to lead, leadership self- efficacy, and leadership skill using inverse-probability weighting of propensity scores to explore differences between the two samples. Unweighted findings suggest that international and domestic students enter programs similarly across in many ways, and leave the immersion program with similar gains. However, a matched-sample comparison suggests that international students’ growth was statistically different in ethical leadership skills, affective- identity motivation to lead, and leadership self-efficacy. Discussion focuses on the benefits of leadership development to international students why campuses could build partnerships between units that serve international students and leadership educators to facilitate a more inclusive campus.

Knowledge sharing in research communities has been considered indispensable to progress in science. The aim of this paper is to analyze the mechanisms restricting knowledge sharing in science. It considers three categories of academia–industry knowledge transfer and a range of individual and contextual variables as possible predictors of knowledge-sharing restrictions.

A unique empirical data sample was collected based on a survey among 212 life science researchers affiliated with universities and other non-profit research institutions. A rich descriptive analysis was followed by binominal regression analysis, including relevant checks for the robustness of the results.

Researchers in academia who actively collaborate with industry are more likely to omit relevant content from publications in co-authorship with other academic researchers; delay their co-authored publications, exclude relevant content during public presentations; and deny requests for access to their unpublished and published knowledge.

This study informs policymakers that different types of knowledge-sharing restrictions are predicted by different individual and contextual factors, which suggests that policies concerning academia–industry knowledge and technology transfer should be tailored to contextual specificities.

This study contributes new predictors of knowledge-sharing restrictions to the literature on academia–industry interactions, including outcome expectations, trust and sharing climate. This study augments the knowledge management literature by separately considering the roles of various academic knowledge-transfer activities in instigating different types of knowledge-sharing restrictions in scientific research.
