Recent studies have urged us to consider the materialities of popular music to evaluate its environmental cost. This article orients this discussion towards the materiality of popular music production. It argues that industrial discussions on sustainable music production practices can overlook the ideologies associated with recording technologies that prompt consumption activities. It highlights the key themes discussed in the industry regarding sustainability in music production across various media platforms. It then analyses how these themes relate to the construction of recording studios instead of their everyday use. Although technologies like compressors are not typically considered in this discussion, this article suggests that aesthetic preferences often lead to consumption activities that must be factored in when considering the ecological costs of music production. This practice indicates that music producers tend to focus on sustainability practices that will not interrupt their core business.

While gender-based violence (GBV) is increasingly recognised as a significant social and political issue, its impact on women educators remains underexamined. In the context of growing concerns about violence against educators and the prevalence of GBV in educational institutions, this study investigates gendered patterns of violence against school leaders in Australian schools. Drawing on 18,172 observations from reports by principals and deputy principals, this analysis explores incidents of bullying, threats of violence, and physical violence to identify disparities in the experiences of men and women school leaders. The analysis determined that women school leaders were more likely to experience threats of violence and bullying at work than their male counterparts. Logistic regression analyses revealed that gender, school sector, and role significantly influence the likelihood of experiencing various forms of workplace violence, with women in secondary schools and those in government or Catholic sectors being particularly vulnerable.

Imagine popular music cultures in the mid-2020s without digital platforms: no song snippets as part of TikTok trends, no Spotify playlists, no music videos on YouTube, no concert streams on Twitch, and no reels and stories on Instagram. Since the mid-2000s, web-based communication and creativity have become increasingly dependent on a relatively small number of digital platforms, which can now be understood as the sociotechnical nucleus of today’s internet (Dolata 2021). Platforms occupy a powerful position in modern media cultures, exerting a decisive influence on the exchange of information, processes of communication, and the organisation of work and markets, as well as creating digital spaces for social action (Dolata and Schrape 2023). Functional rules, defined by the tech companies behind the platforms, are expressed in the platforms’ interfaces and algorithmic logics (van Dijck et al. 2018). These functional rules do not determine the behaviour of cultural workers active on platforms, but they can substantially influence it – notably in the field of popular music. Due to the platforms’ pre-defined media formats, such as short-form videos, playlists, and similar content, it appears feasible to hypothesise that musicians endeavour to adapt their content – including songs, videos, visual media, and lyrics – to achieve optimal visibility within the digital spaces facilitated by these platforms.

On the basis of signaling and trust theories, we explore the impact of focal firms’ environmental, social, and governance (ESG) performance on their collaborative innovation (co-innovation). We argue that high ESG performance serves as a positive signal that focal firms engage less in opportunistic behavior in the co-innovation process. This, in turn, makes it easier for focal firms to gain the trust of potential external innovation collaborators (collaborators) and ultimately increases the level of co-innovation in focal firms. Guided by signaling and trust theories, we further argue that heavy polluting firm attributes and historical co-innovation alter the impact of ESG signals on collaborators’ trust, which in turn leads to heterogeneity in the positive impact of ESG performance on firms’ co-innovation. Based on empirical data on A-share manufacturing companies listed in China from 2010 to 2021, we obtained empirical evidence to support the above theoretical arguments. This study provides new insights for a refined understanding of the innovation consequences of ESG performance and important implications for shareholders and policymakers to better encourage and guide firms in co-innovation.

Boundary points on the moduli space of pointed curves corresponding to collisions of marked points have modular interpretations as degenerate curves. In this paper, we study degenerations of orbifold projective curves corresponding to collisions of stacky points from the point of view of noncommutative algebraic geometry.

Haemonchus contortus is a parasitic nematode that causes significant economic losses in ruminant livestock worldwide. In this study, we assessed the global genetic diversity and population structure of H. contortus using mitochondrial COX1 and ribosomal ITS2 sequences retrieved from the NCBI GenBank database. In total, 324 haplotypes of the COX1 and 72 haplotypes of the ITS2 were identified. The haplotype diversity values were all higher than 0.5, and the nucleotide diversity values were higher than 0.005. The Tajima’s D value for COX1 (−1.65634) was higher than that for ITS2 (−2.60400). Fu’s Fs, Fu and Li’s D (FLD), and Fu and Li’s F (FLF) values also showed high negative values, indicating a high probability of future population growth. In addition, the high fixation index (FST) value suggests significant genetic differentiation among populations. The haplotype networks of H. contortus populations based on COX1 sequences revealed clear geographic clustering, whereas ITS2 sequences showed more haplotype admixture across regions. The results of phylogenetic analyses were consistent with the haplotype networks. These findings highlighted that H. contortus populations exhibit significant genetic variation and are undergoing rapid population expansion, with clear genetic differences across geographic regions. This study established critical baseline data for future molecular epidemiology studies, which could guide region-specific parasite surveillance and targeted control strategies, thus helping to mitigate the risk of cross-border parasite transmission and drug resistance.

In this paper we adopt the probabilistic mean value theorem in order to study differences of the variances of transformed and stochastically ordered random variables, based on a suitable extension of the equilibrium operator. We also develop a rigorous approach aimed at expressing the variance of transformed random variables. This is based on a joint distribution which, in turn, involves the variance of the original random variable, as well as its mean residual lifetime and mean inactivity time. Then we provide applications to the additive hazards model and to some well-known random variables of interest in actuarial science. These deal with a new notion, called the ‘centred mean residual lifetime’, and a suitably related stochastic order. Finally, we also address the analysis of the differences of the variances of transformed discrete random variables thanks to the use of a discrete version of the equilibrium operator.

Pronatalist policies are on the rise in many countries. These have stemmed from several motivators, including economic concerns, nationalism, and promotion of traditional family values. As global fertility rates have fallen, many countries have instilled pronatalist policies to encourage people to have more children. In other countries, including the United States, religious traditionalism and nationalist forces have fueled pronatalist policies as a counter to improved female empowerment and global immigration. No matter the stated motivation, government-sanctioned pronatalism overtly leads to reproductive coercion or covertly results in limited reproductive autonomy as collateral damage. Herein, we review global examples of prior and current pronatalist policies, outlining the motivators for their promotion within each case. We demonstrate how these policies are not only ineffective, but are dangerous to the health and well-being of women and other populations and are in direct conflict with modern reproductive goals, reproductive justice, and decades of efforts towards achieving gender parity.

Resilient enterprises thrive under adverse conditions given their preparedness for crises. This study proposes that executives’ vigilant managerial cognition is essential for enhancing enterprise resilience. To measure this cognition, the study developed a textual index using machine learning methods and analyzed a sample of Chinese enterprises to assess the impact of executives’ vigilant managerial cognition on enterprise resilience. The findings indicate that this cognition is positively related to enterprise resilience, where the relationship is stronger in enterprises with robust internal controls. The primary contribution of this study is the conceptualization of vigilant managerial cognition and its established positive relationship with enterprise resilience. Furthermore, by introducing a novel quantitative measure of managerial cognition through textual analysis and machine learning, the study paves the way for future research on managerial cognition within firms.
