FedACQ: adaptive clustering quantization of model parameters in federated learning
Authors: Tian Tingting , Shi Hongjian , Ma Ruhui , Liu Yuan
Published: November 2023

Purpose

For privacy protection, federated learning based on data separation allows machine learning models to be trained on remote devices or in isolated data devices. However, due to the limited resources such as bandwidth and power of local devices, communication in federated learning can be much slower than in local computing. This study aims to improve communication efficiency by reducing the number of communication rounds and the size of information transmitted in each round.

Design/methodology/approach

This paper allows each user node to perform multiple local trainings, then upload the local model parameters to a central server. The central server updates the global model parameters by weighted averaging the parameter information. Based on this aggregation, user nodes first cluster the parameter information to be uploaded and then replace each value with the mean value of its cluster. Considering the asymmetry of the federated learning framework, adaptively select the optimal number of clusters required to compress the model information.

Findings

While maintaining the loss convergence rate similar to that of federated averaging, the test accuracy did not decrease significantly.

Originality/value

By compressing uplink traffic, the work can improve communication efficiency on dynamic networks with limited resources.
Exploring alternative discourses about datafication in a speculative youth participatory action research curriculum
Authors: Aleman Ezequiel
Published: November 2023

Purpose

This paper aims to address the limitations in designing educational approaches that apply critical approaches to data literacy, given the obscure nature of digital platforms, which leave youth unable to develop discourses that challenge dominant narratives about the role of data in their lives. The purpose of this study is to propose and evaluate a critical data literacy approach that empowers youth to engage with data from a sociocultural perspective using a speculative participatory research approach that affords opportunities to develop alternative discourses.

Design/methodology/approach

This is a multiple-case study that involves five alternative schools in Uruguay which implemented the Nayah-Irú curriculum over ten weeks leading to the development of six distinct research projects about the materialization of data in youth lives. The curriculum incorporates an alternate reality game (ARG) to engage youth in critical data literacy, based on the principles of Youth Participatory Action Research (YPAR) epistemology and Speculative Civic Literacies.

Findings

The findings of this study highlight the integration of speculative storytelling and real-life experiences in developing alternative discourses about datafication. The analysis revealed instances of discursive closure among the youth, but through the curriculum's speculative fiction elements, such as the narrative of Nayah-Irú, emotional connections were formed, leading to increased engagement, critical inquiry, and problem framing.

Research limitations/implications

The study conducted on the Nayah-Irú curriculum shows its effectiveness in engaging youth and educators in critical data literacy by affording opportunities for youth to engage in the analysis of their personal data literacies in an alternative world. Bringing speculative approaches to data literacy can open new avenues for exploring data literacy with youth in ways that center their voices and help them overcome different forms of discursive closure.

Originality/value

This study offers new insights into critical data literacy education blending youth participatory action research epistemologies with a speculative literacies framework to support youth in developing alternative discourses regarding the role of data in their lives.

Authors: Jaffu Richard , Ndiango Sinyati , Elias Ruth , Gabriel Debora , Ringo Denis
Published: November 2023

Purpose

This study aimed to examine the influence of psychological capital on the students' academic success in a PhD journey in Tanzania.

Design/methodology/approach

A cross-sectional survey design was used and data were collected through structured questionnaires from 200 PhD students in Tanzania. Confirmatory factor analysis was used to test the measurement model. The hypotheses were empirically tested using structural equation modeling (SEM).

Findings

The findings affirm that psychological capital in terms of hope, self-efficacy, resilience and optimism are significant predictors of students' academic success in a PhD journey.

Originality/value

To the best of the authors' knowledge, this paper is among the first to comprehensively examine the influence of psychological capital on students' academic success in PhD studies. Previous studies have primarily focused on the undergraduate level. Additionally, this study extends the applicability of conservation of resource (COR) theory to the context of PhD students, demonstrating that psychological capital serves as a crucial resource for them to achieve success in their PhD studies.
The effect of corpus-assisted language teaching on academic collocation acquisition by Iranian advanced EFL learners
Authors: Baghiat Esfahani Mohamad Javad , Ketabi Saeed
Published: November 2023

Purpose

This study attempts to evaluate the effect of the corpus-based inductive teaching approach with multiple academic corpora (PICA, CAEC and Oxford Corpus of Academic English) and conventional deductive teaching approach (i.e., multiple-choice items, filling the gap, matching and underlining) on learning academic collocations by Iranian advanced EFL learners (students learning English as a foreign language).

Design/methodology/approach

This is a quasi-experimental, quantitative and qualitative study.

Findings

The result showed the experimental group outperformed significantly compared with the control group. The experimental group also shared their perception of the advantages and disadvantages of the corpus-assisted language teaching approach.

Originality/value

Despite growing progress in language pedagogy, methodologies and language curriculum design, there are still many teachers who experience poor performance in their students' vocabulary, whether in comprehension or production. In Iran, for example, even though mandatory English education begins at the age of 13, which is junior and senior high school, students still have serious problems in language production and comprehension when they reach university levels.
Room for diversity: a review of research and industry approaches to inclusive workplaces
Authors: Tagliaro Chiara , Migliore Alessandra , Mosca Erica Isa , Capolongo Stefano
Published: November 2023

Purpose

This paper aims to explore how the scientific literature and company reports have addressed inclusive workplace design and strategies to date.

Design/methodology/approach

This paper adopts a scoping review to answer the following question: To what extent is inclusion present in workplace design and related strategies? An analysis of 27 scientific papers and 25 corporate social responsibility reports of the highest-ranked companies in the Great Place to Work global ranking disentangles the main aspects related to workplace design and strategies for promoting inclusion.

Findings

This paper opens avenues for four macro-categories of diversity (psycho-physical aspects; cultural aspects; socio-economic conditions; and ability, experience and strengths) to support the development of inclusive workplace design and strategy. Besides, multiple spatial scales emerged as material and immaterial elements of the workplace encountering inclusion and diversity.

Originality/value

Nowadays, the workforce is becoming more diverse. Although diversity, equity and inclusion (DE&I) has become key to many organizations, it remains unclear how DE&I principles are applied in workspace design and strategies. This scoping review provides a novel perspective on the topic by integrating scientific knowledge and practice-based approaches which still address this matter independently.

Buffering negative impact of psychological contract breach on employee voice behavior: the moderating role of globally responsible business leadership
Authors: Tan Alice J.M. , Xiao Shujuan , Jiang Katie Kaiqi , Chen Zitong
Published: November 2023

Purpose

This study aims to examine the relationship between employees’ psychological contract breach and two types of voice behavior based on the social exchange theory. Additionally, the study explores the role of globally responsible business leadership in buffering the negative impacts of psychological contract breach on voice.

Design/methodology/approach

Survey data was collected from Chinese full-time employees and the final sample size is 337. Partial least squares structural equation modeling was used to test the hypotheses.

Findings

Findings indicate that psychological contract breach (PCB) has a positive and significant impact on employee aggressive voice behavior (AVB), while its relationship with constructive voice behavior (CVB) is not significant. Furthermore, globally responsible business leadership (GRBL) weakens the negative relationship between PCB and CVB, while strengthens the positive relationship between PCB and AVB.

Practical implications

The findings assist organizations in better recognizing the detrimental consequences of psychological contract breach. Second, the findings serve as a reminder to managers of the benefits of displaying globally responsible business leadership. Third, managers should recognize the complexities of globally responsible business leadership.

Originality/value

First, this study sheds new light on the impact of PCB on employees’ desirable and undesirable proactive behaviors by investigating how and when psychological contract breach affects two types of voice behavior. Second, the moderating role of GRBL further enriches our understanding of how to buffer negative effects of PCB and the desirable function of GRBL. Third, this study enriches the social exchange theory by investigating whether the leader−employee relationship will compensate for the failure of organization−employee relationship.
Effects of oil price uncertainty on corporate investment of Islamic stocks: evidence from the extreme event of Covid-19 pandemic
Authors: Khan Muhammad Tariq , Rashid Abdul , Khan Mushtaq Hussain , Zaman Asif , Ali Shahid
Published: November 2023

Purpose

This paper aims to examine the effects of oil price uncertainty on corporate investment of Islamic stocks during the COVID-19 pandemic.

Design/methodology/approach

The study uses a panel data set that covers 398 listed Islamic stocks from seven major Asia Pacific countries over the period of five years from 2017 to 2021, yielding 1,990 observations. Specifically, this paper investigates the said association by combining the real options theory regarding investment and the panel data-based econometric method that captures the dynamic relationship, the generalized method of moments estimators.

Findings

The findings show that the relationship between the oil price volatility and corporate investment of Islamic stocks is significant and nonlinear in nature, suggesting the presence of both the growth options and the waiting options. Overall, the results reveal that corporate investment of Islamic stocks is hindered during the unprecedented corona crash, when oil price increases at exponential rates.

Practical implications

The findings suggest that considering the information caused by unprecedented events like the COVID-19 pandemic is crucial for investment decisions of Islamic stocks. Therefore, policymakers and regulators should incorporate the impact of oil price uncertainties caused by unprecedented events like the COVID-19 pandemic on firm’s investment expansion and diversification strategies.

Originality/value

To the best of the authors’ knowledge, this paper is the first to examine the relationship between the investment of Islamic stocks and the oil price uncertainty under compound options theory in top Asian oil-importing countries.
Unilateral economic sanctions and food security
Authors: Ray Ronjini , Siddiqui Jamshed Ahmad
Published: November 2023

Purpose

This paper aims to highlight the lacunae in international trade law concerning unilateral economic sanctions that impact food security.

Design/methodology/approach

This paper adopts a literature review to establish that unilateral economic sanctions impact food security and a descriptive assessment of a few such sanctions. Thereafter, it adopts doctrinal analysis of such sanctions under World Trade Organization law and identifies the gaps to address the specific situation of unilateral economic sanctions that impact food security.

Findings

Unilateral economic sanctions are not effectively regulated under international law. Unilateral economic sanctions are known to impact food security not just in the targeted country but also in third countries. Under international trade law, the security exception under Article XXI of the General Agreement on Tariffs and Trade (GATT) does not currently require an assessment of necessity and proportionality of measure. However, there is scope for such an assessment in the future depending on the circumstances, particularly if a measure impacts the rights and interests of third countries by impacting global food security.

Originality/value

The paper conducts a literature review of the impact of unilateral economic sanctions on food security. It highlights the gap in the interpretation of GATT Article XXI when assessing such sanctions that adversely impact the food security of third countries. The paper may be helpful for academics, policymakers, international organizations, non-governmental organisations, etc.
Digital technologies and knowledge processes: new emerging strategies in international business. A systematic literature review
Authors: Massa Silvia , Annosi Maria Carmela , Marchegiani Lucia , Messeni Petruzzelli Antonio
Published: November 2023

Purpose

This study aims to focus on a key unanswered question about how digitalization and the knowledge processes it enables affect firms’ strategies in the international arena.

Design/methodology/approach

The authors conduct a systematic literature review of relevant theoretical and empirical studies covering over 20 years of research (from 2000 to 2023) and including 73 journal papers.

Findings

This review allows us to highlight a relationship between firms’ international strategies and the knowledge processes enabled by applying digital technologies. Specifically, the authors discuss the characteristics of patterns of knowledge flows and knowledge processes (their origin, the type of knowledge they carry on and their directionality) as determinants for the emergence of diverse international strategies embraced by single firms or by populations of firms within ecosystems, networks, global value chains or alliances.

Originality/value

Despite digital technologies constituting important antecedents and critical factors for the internationalization process, and international businesses in general, and operating cross borders implies the enactment of highly knowledge-intensive processes, current literature still fails to provide a holistic picture of how firms strategically use what they know and seek out what they do not know in the international environment, using the affordances of digital technologies.
Functioning of the register of beneficial owners: findings from Poland
Authors: Matras Tomasz Michał
Published: November 2023

Purpose

The implementation of the Directive 2015/849 of the European Parliament and of the Council of 20 May 2015 on the prevention of the use of the financial system for the purposes of money laundering or terrorist financing resulted in the enactment by the Polish Parliament of the Act of March 1, 2018, on the prevention of money laundering and terrorist financing. One of the most important issues identified in the Act was the establishment of the Central Register of Beneficial Owners. The purpose of this paper is to critically analyze the functioning of the Register in Poland from the perspective of three years since its establishment. The text presents the most important problems faced by reporting institutions and obliged entities due to discrepancies in the interpretation of the Act’s provisions – especially in terms of the definition of a beneficial owner.

Design/methodology/approach

The basic research approach was a comparative content analysis method. The objects of analysis included Polish Laws, Directive of the European Parliament and the Council (EU) 2015/849 and the judgment of the Court of Justice of the European Union. The theoretical legislative assumptions contained in the Acts were compared with reports, studies and communications prepared by public and private institutions. This made it possible to draw conclusions regarding the causes of problems with the functioning of the Register in Poland.

Findings

The results of the research showed that the ambiguity of the definition of the beneficial owner leads to a number of problems on the part of reporting institutions, such as companies, foundations and associations. On the other hand, a large part of the data entered in the Register is questioned by obliged entities. The lack of personal data protection is also a problem. Consequently, this reduces the value of the Register as a tool that effectively mitigates the risk of money laundering.

Research limitations/implications

The research focused only on the functioning of the Central Register of Beneficial Owners in Poland. The subject of the analysis addressed problems with the definition of beneficial owner, issues of data quality and openness and the process of verifying the Register’s data. The technical aspects of the Register operation and the financial penalties imposed by public oversight institutions were not reviewed. Also, no comparison was made with other European Union (EU) member states that have implemented Directive of the European Parliament and of the Council (EU) 2015/849.

Originality/value

This study discusses the important issue of regulatory requirements introduced under EU regulations for private companies. Familiarization of companies, NGOs and obliged entities with the conclusions of the study can positively influence the consolidation of the correct interpretative path. In addition, to the best of the author’s knowledge, this is the first scientific text that identifies and systematizes the most important problems of the Register’s functioning in Poland.
Trait emotional intelligence among future leaders: how business students are prepared for the VUCA world
Authors: Zawadzki Kamil , Wojdyło Monika , Muszyńska Joanna
Published: November 2023

Purpose

This article aims to analyse the trait emotional intelligence (TEI) of business students of various programmes. This study aims to answer the question, to what extent these future leaders are uniformly equipped with essential emotional intelligence competences, necessary in the VUCA world.

Design/methodology/approach

The Trait Emotional Intelligence Questionnaire (TEIQue) was used to measure TEI of 120 business students. Spearman's and Tau–Kendall's rank correlation coefficients show the strength of the correlation between age and TEI level. The non-parametric Mann–Whitney U test was employed to evaluate the consistency of TEI-level distributions in selected subgroups of respondents.

Findings

Future business leaders and management specialists are unequally prepared to manage teams and organizational change effectively. Their TEI distribution is significantly different regarding the type of programme of study. Students of “social fields” (Management, Communication and Psychology in Business) show higher TEI than students of “analytical fields” (Economics, Finance and Accounting, Logistics). Master's students are characterized by higher TEI compared to undergraduates. However, there were no statistically significant differences in TEI between: full-time and part-time, female and male, as well as working and non-working students.

Practical implications

The results provide valuable guidance for organizations recruiting junior managers and for business universities.

Originality/value

This research was based on a well-established concept of emotional intelligence using a reliable research tool. The obtained results complement the existing research on TEI of various professional groups and provide a precious reference point for future, more in-depth analyses of TEI.
The consequences of artificial intelligence: an investigation into the impact of AI on job displacement in accounting
Authors: Rawashdeh Awni
Published: November 2023

Purpose

The advent of artificial intelligence (AI) in the accounting landscape marks a significant shift, promising gains in efficiency and accuracy but also eliciting concerns about job displacement (JD) and broader socio-economic implications. This study aims to provide an in-depth understanding of how AI’s integration in accounting contributes to JD, reshapes decision-making processes and reverberates across economic and social dimensions. It also offers evidence-based policy recommendations to mitigate adverse outcomes.

Design/methodology/approach

Leveraging a cross-sectional survey disseminated through Facebook, this research used snowball sampling to target a diverse cohort of accounting professionals. The collected data were subjected to meticulous analysis through descriptive and regression models, facilitated by SmartPLS 4 software.

Findings

The analysis revealed a significant correlation between AI’s increasing role in accounting and a heightened rate of JD. This study found that this displacement is not isolated; it has tangible repercussions on decision-making paradigms, economic well-being, professional work dynamics and social structures. These insights corroborate existing frameworks, including, but not limited to, theories of technological unemployment and behavioural adjustments.

Research limitations/implications

Although providing valuable insights, this study acknowledges limitations such as the restricted sample size, the cross-sectional nature of the survey and the inherent biases of self-reported data. Future research could aim to extend these initial findings by adopting a longitudinal approach and potentially integrating external data sources.

Practical implications

As AI technology becomes increasingly ingrained in accounting practices, there is an urgent need for coordinated action among stakeholders. Policy recommendations include focused efforts on talent retention, investment in upskilling programs and the establishment of support mechanisms for those adversely affected by AI adoption.

Originality/value

By synthesising a range of theoretical perspectives, this study offers a comprehensive exploration of AI’s multi-dimensional impacts on the accounting profession. It stands out for its nuanced examination of JD and its economic and social implications, thereby contributing to both academic discourse and policy formulation. This work serves as an urgent call to action, highlighting the need for strategies that both exploit AI’s potential benefits and protect the workforce from its disruptive impact.
Workplace violence in extreme settings: the case of aged care workers and the role of anti-violence HRM and trust of managers on intention to leave
Authors: Bartram Timothy , Cavanagh Jillian , Halvorsen Beni , Pariona-Cabrera Patricia , Borg Jessica , Walker Matthew , Kia Narges
Published: November 2023

Purpose

Aged-care work has become an extreme form of work. Anti-violence HRM, comprising practices to combat workplace violence, is important in an industry with widespread violence. In this paper, we employ social exchange theory to better understand the effect of anti-violence HRM and trust in the manager on perceived nurse and PCA cynicism working in Australian aged care facilities and their subsequent intention to leave.

Design/methodology/approach

This study used a mixed method with two stages. Stage 1 comprised semi-structured interviews with 10 managers and 50 nurses and PCAs working in Australian aged care facilities. Stage 2 comprised a survey of nurses and PCAs with a total of 254 completed responses in Time 1 (first wave) and 225 completed responses in Time 2 (second wave).

Findings

We tested three hypotheses and reported that interestingly anti-violence HRM was positively associated with organisational cynicism. Organisational cynicism mediated the relationship between anti-violence HRM and intention to leave. Worker trust in the manager moderated the relationship between anti-violence HRM practices and organisational cynicism, such that high levels of trust in the manager increased the effect of anti-violence HRM practices to reduce organisational cynicism and subsequently reduce intention to leave.

Originality/value

We find evidence that in aged care, workers' trust in their managers is critical for effectual anti-violence HRM. We argue that implementation of HRM practices may be more complex in extreme work settings. It is crucial to study HRM in situ and understand the root of social exchange(s) as a foundation for HRM to influence employee attitudes and behaviour.
Turning the invisible into the visible: exploring consumers’ perceptions towards sustainable water consumption
Authors: Patsiaouras Georgios
Published: November 2023

Purpose

This study aims to elaborate on the interface between water scarcity and consumption and, specifically to focus on, how consumers’ perceptions and views towards (un)sustainable water consumption can inform the development of sustainable water practices and environmental policies.

Design/methodology/approach

A qualitative methodology was adopted, consisting of 34 in-depth interviews with consumers, in four cities in the United Kingdom (UK). The semi-structured interviews sought to examine sustainable water consumption practices in more depth within an unexplored context, and secondary data were also used to explore the phenomenon in more depth.

Findings

The findings provide novel theoretical and empirical insights around the invisibility and imperceptibility of (un)sustainable water consumption. The findings suggest how interdisciplinary and collaborative practices can enhance more responsible and sustainable consumption of water resources in the UK.

Practical implications

The study can inform marketing strategies on community engagement with localised water sustainable actions and encourage policymakers to develop concrete marketing communications and increased public awareness regarding water scarcity.

Social implications

Considering the slow growth of water scarcity, the findings can prompt marketing scholars to explore similar phenomena, within seemingly unaffected countries, urban centres, industries and marketplaces.

Originality/value

Previous studies focused on the measurement of household water consumption in the water-scarce context of the Southern Hemisphere. Challenging geographical perceptions of water shortage, this study focuses on the UK and highlights how the multidimensional, finite and invisible nature of water consumption requires collaborative efforts in tackling water scarcity.
Leveraging PDS teacher preparation grants: a majority–minority research university’s approach to increasing the diverse teacher pipeline
Authors: Feinberg Joseph R. , Bey Yasmine
Published: November 2023

Purpose

A primary goal of the Collaboration and Resources for Encouraging and Supporting Transformations in Education (CREST-Ed) program was to increase the number of highly qualified, minoritized teachers committed to teaching in minority-serving, high-need school districts. This study's purpose was to evaluate the CREST-Ed program's impact on teacher residency outcomes using multiple sources of program evaluation data collected during the five-year grant.

Design/methodology/approach

This study of a federal Teacher Quality Partnership (TQP) grant at Georgia State University (GSU), a minority-serving institution (MSI) and research university, shows teacher residency programs can improve the diverse teacher pipeline. The grant, CREST-Ed, provided professional development schools (PDS) support for four urban and 23 rural school districts through partnerships with GSU, Albany State University (ASU) and Columbus State University (CSU).

Findings

The study findings suggest that teacher preparation grants can be leveraged to recruit traditionally minoritized teachers of color to increase the diverse teacher pipeline and strengthen PDS partnerships.

Originality/value

Both urban and rural PDSs could benefit from teacher residency programs like the CREST-Ed model that catered to the unique needs of each school and partnership district.
Increases in understory plant cover and richness persist following restoration treatments inPinus ponderosaforests

Published: November 2023

A combination of forest thinning followed by prescribed burning is widely applied in the western United States to increase ecosystem resistance and resilience to disturbances. Understory plant community responses may be driven by both management treatments and climatic factors. Thus, responses to treatments during a 20‐year megadrought have implications for the role of management in fostering adaptive capacity to climate change.

We used a network of five sites (600 plots) spanning an environmental gradient in ponderosa pine (Pinus ponderosa) forests of the American Southwest, an ecosystem that is broadly distributed and actively managed throughout the western United States. We used repeated long‐term monitoring data to quantify plant community responses to treatment 1–5‐, 6–10‐ and >10‐year post‐implementation. Specifically, we focussed on the effects of treatment and abiotic conditions on native and non‐native plant cover and species richness and the proportion of native species with northern (cool‐mesic) biogeographic affinities.

Overall, thinning and prescribed burning nearly doubled native cover and increased native species richness by about 50% relative to untreated controls. These effects persisted for over a decade after treatment, even under the influence of significant and persistent drought. Cover and richness were also greater on intermediate to wet sites. Finally, native species with northern biogeographic affinities were reduced for up to 5 years after treatment relative to those with southern (warm‐xeric) affinities, and in dry years, indicating that both management and interannual climate variability may foster shifts to plant communities that are more resilient to a warming climate.

Synthesis and applications. In ponderosa pine forests of the American Southwest, tree thinning followed by prescribed burning will generally promote restoration goals of increasing resilience to climate change by enhancing the diversity and abundance of native understory plant species, even during a persistent 20‐year megadrought.
Tillage agriculture and afforestation threaten tropical savanna plant communities across a broad rainfall gradient in India
Authors: Nerlekar Ashish N. , Munje Avishkar , Mhaisalkar Pranav , Hiremath Ankila J. , Veldman Joseph W.
Published: November 2023

The consequences of land‐use change for savanna biodiversity remain undocumented in most regions of tropical Asia. One such region is western Maharashtra, India, where old‐growth savannas occupy a broad rainfall gradient and are increasingly rare due to agricultural conversion and afforestation.

To understand the consequences of land‐use change, we sampled herbaceous plant communities of old‐growth savannas and three alternative land‐use types: tree plantations, tillage agriculture and agricultural fallows (n = 15 sites per type). Study sites spanned 457 to 1954 mm of mean annual precipitation—corresponding to the typical rainfall range of mesic savannas globally.

Across the rainfall gradient, we found consistent declines in old‐growth savanna plant communities due to land‐use change. Local‐scale native species richness dropped from a mean of 12 species/m2in old‐growth savannas to 8, 6 and 3 species/m2in tree plantations, fallows and tillage agriculture, respectively. Cover of native plants declined from a mean of 49% in old‐growth savannas to 27% in both tree plantations and fallows, and 4% in tillage agriculture. Reduced native cover coincided with increased cover of invasive species in tree plantations (18%), fallows (18%) and tillage agriculture (3%).

In analyses of community composition, tillage agriculture was most dissimilar to old‐growth savannas, while tree plantations and fallows showed intermediate dissimilarity. These compositional changes were driven partly by the loss of characteristic savanna species: 65 species recorded in old‐growth savannas were absent in other land uses. Indicator analysis revealed 21 old‐growth species, comprised mostly of native savanna specialists. Indicators of tree plantations (nine species) and fallows (13 species) were both invasive and native species, while the two indicators of tillage agriculture were invasive. As reflective of declines in savanna communities, mean native perennial graminoid cover of 27% in old‐growth savannas dropped to 9%, 7%, and 0.1% in tree plantations, fallows and tillage agriculture, respectively.

Synthesis. Agricultural conversion and afforestation of old‐growth savannas in India destroys and degrades herbaceous plant communities that do not spontaneously recover on fallowed land. Efforts to conserve India's native biodiversity should encompass the country's widespread savanna biome and seek to limit conversion of irreplaceable old‐growth savannas.
Epistemic injustice in experiences of young people with parents with mental health challenges
Authors: Yates Scott , Gladstone Brenda , Foster Kim , Silvén Hagström Anneli , Reupert Andrea , O’Dea Lotti , Cuff Rose , McGaw Violette , Hine Rochelle
Published: November 2023

Amongst the impacts of growing up with a parent with mental health challenges is the experience of stigma‐by‐association, in which children and young people experience impacts of stigmatisation due to their parent’s devalued identity. This article seeks to expand our understanding of this issue through an abductive analysis of qualitative data collected through a codesign process with young people. Results indicate that young people’s experiences of stigmatisation can be effectively understood as experiences of epistemic injustice. Participants expressed that their experiences comprised ‘more than’ stigma, and their responses suggest the centrality to their experiences of being diminished and dismissed in respect of their capacity to provide accurate accounts of their experiences of marginalisation and distress. Importantly, this diminishment stems not only from their status as children, and as children of parents with mental health challenges but operates through a range of stigmatised identities and devalued statuses, including their own mental health status, sexual minoritisation, disability and social class. Forms of epistemic injustice thus play out across the social and institutional settings they engage with. The psychological and social impacts of this injustice are explored, and the implications for our understanding of stigma around family mental health discussed.
Peoplehood and the Orthodox person: a view from central Serbia
Authors: Lackenby Nicholas
Published: November 2023

Practising Orthodox Christians in central Serbia live their liturgical lives within the idiom of Serbian peoplehood. This article probes the ‘people’ (narod) – perceived locally as an historically and geographically rooted ethno‐moral collectivity – as a core concept of belonging which is key for understanding post‐Yugoslav Orthodox life. The ‘people’ functions as a this‐worldly collective identity within which my interlocutors situate themselves as Orthodox persons, and through which they approach the Divine. Threats to Serb identity serve to foreground peoplehood as the supposedly prime site for Orthodox flourishing. Moving beyond state‐oriented analyses of ‘religious nationalism’, the article demonstrates not how ‘nationalism’ can be understood through ‘religion’, but how, to use Orthodox Serbs’ own terminology, faith can be understood through the prism of peoplehood.
Prescription for Cash? Cash Support to Low‐Income Families in Maternal and Pediatric Health Care Settings
Authors: MCCONNELL MARGARET , AGARWAL SUMIT , HANSON ERIKA , MCCRADY ERIN , PARKER MARGARET G. , BONA KIRA
Published: November 2023

Policy Points

Pregnancy and childhood are periods of heightened economic vulnerability, but current policies for addressing health‐related social needs, including screening and referral programs, may be insufficient because of persistent gaps, incomplete follow‐up, administrative burden, and limited take‐up.

To bridge gaps in the social safety net, direct provision of cash transfers to low‐income families experiencing health challenges during pregnancy, infancy, and early childhood could provide families with the flexibility and support to enable caregiving, increase access to health care, and improve health outcomes.
The interaction between wheat and pea protein influences the final chemical and sensory characteristics of extruded high moisture meat analogs
Authors: Richter Jana K. , Montero Maria Laura , Ikuse Marina , Wagner Caleb E. , Ross Carolyn F. , Saunders Steven R. , Ganjyal Girish M.
Published: November 2023

Plant‐based meat analog products, including those produced by extrusion processing, have become increasingly popular. Complete comprehension of the texturization mechanism and the formation of fibrousness would help improve existing products and extend the variety of plant sources used. Therefore, this study aimed to provide improved insight into the mechanism of texturization during the processing of high‐moisture meat analog (HMMA) products. Blends with different wheat and pea protein ratios (100:0, 80:20, 60:40, 40:60, 20:80, and 0:100 wheat:pea) were extruded at a screw speed of 400 rpm, two different moisture contents (50% and 55%), and a feed rate of 90 g/min using a co‐rotating twin‐screw extruder. Extrudates were analyzed for their texture, free sulfhydryl groups, disulfide bonds, and solubility in different extractants relative to the raw ingredient blends. In addition, a sensory analysis was conducted using the rapid and cost‐effective “rate‐all‐that‐apply” (RATA) methodology. The interplay between the two protein types had synergistic effects on the system parameters torque, pressure, and specific mechanical energy, as well as on some textural and sensory parameters. Molecular analyses were not influenced by the interplay between wheat and pea protein as the molecular analyses followed linear trends with the pea inclusion level. Analysis of protein solubility suggests that the texturization mechanism differs slightly depending on the protein type. It is suggested that the texturization of wheat protein depends highly on disulfide bonds, whereas the texturization of pea protein relies on the combination of disulfide bonds and non‐covalent interactions. Additionally, RATA was found to be a valuable tool for HMMA products.

In this paper, we use remotely sensed imagery to identify the location and size of animal feeding operations in the Maumee River Watershed, a key drainage area to Lake Erie's Western Basin, which has recently experienced severe harmful algal blooms. We then estimate the relationship between the intensity of animal feeding operations in the watershed and surface water body concentrations of dissolved reactive phosphorus (DRP), the pollutant most responsible for algal growth. We find that stream reaches with relatively larger increases in upstream animal feeding exposure experience significantly higher increases in concentrations of DRP. The average marginal upstream animal feeding operation in the watershed increases downstream DRP concentrations by between 10% and 15%. In contrast, when restricting the analysis to include only permitted operations, coefficient estimates are practically zero and statistically insignificant. Our work presents evidence that the increasing intensity of animal feeding operations contributes to water quality problems. Permitting and identification of animal feeding operations is therefore important for managing runoff and correctly attributing the causes of excess nutrients in surface water bodies.

The only occurrence of Lower Triassic silicic volcanic rocks within the South China Block is in the Qinzhou Bay area of Guangxi Province. LA‐ICP‐MS zircon U‐Pb dating reveals that volcanic rocks of the Beisi and Banba formations formed between 248.8 ± 1.6 and 246.5 ± 1.3 Ma, coeval with peraluminous granites of the Qinzhou Bay Granitic Complex. The studied rhyolites and dacites are characterized by high SiO2, K2O, and Al2O3, and low MgO, CaO, and P2O5 contents and are classified as high‐K calc‐alkaline S‐type rocks, with A/CNK = 0.98–1.19. The volcanic rocks are depleted in high field strength elements, e.g., Nb, Ta, Ti, and P, and enriched in large ion lithophile elements, e.g., Rb, K, Sr, and Ba. Although the analyzed volcanic rocks have extremely enriched zircon Hf isotopic compositions (εHf(t) = –29.1 to –6.9), source discrimination indicators and high calculated Ti‐in‐zircon temperatures (798–835°C) reveal that magma derived from enriched lithospheric mantle not only provided a heat source for anatectic melting of the metasedimentary protoliths but was also an endmember component of the S‐type silicic magma. The studied early Triassic volcanics are inferred to have formed immediately before closure of the Paleo‐Tethys Ocean in this region, as the associated subduction would have generated an extensional setting in which the mantle‐derived upwelling and volcanic activity occurred.

Identification and anatomy of oceanic arcs within ancient orogenic belt are significant for better understanding the tectonic framework and closure process of paleo‐ocean basin. This article summarizes the geological, geochemical, and geochronological characteristics of upper crust of Proto‐Tethyan Lajishan intra‐oceanic arc and provides new data to constrain the subduction evolution of the South Qilian Ocean. The intra‐oceanic arc volcanic rocks, including intermediate–mafic lava, breccia, tuff, and minor felsic rocks, are distributed along southern part of the Lajishan ophiolite belt. Geochemical and isotopic compositions indicate that the intermediate–mafic lava were originated from depleted mantle contaminated by sediment melts or hydrous fluids, whereas the felsic rocks were likely generated by partial melting of juvenile mafic crust in intra‐oceanic arc setting. Zircons from felsic rocks yield consistent and concordant ages ranging from 506 to 523 Ma, suggesting these volcanic rocks represent the relicts of upper crust of the Cambrian intra‐oceanic arc. Combined with the Cambrian forearc ophiolite and accretionary complex, we suggest that the Cambrian intra‐oceanic arc in the Lajishan ophiolite belt is belonging to the intra‐oceanic arc system which was generated by south‐directed subduction in the South Qilian Ocean at a relatively short interval between approximately 530 and 480 Ma.

Reductions in soil moisture due to prolonged episodes of drought can potentially affect whole forest ecosystems, including soil microorganisms and their functions. We investigated how the composition of soil microbial communities is affected by prolonged episodes of water limitation. In a mesocosm experiment with Scots pine saplings and natural forest soil maintained at different levels of soil water content over 2 years, we assessed shifts in prokaryotic and fungal communities and related these to changes in plant development and soil properties. Prolonged water limitation induced progressive changes in soil microbial community composition. The dissimilarity between prokaryotic communities at different levels of water limitation increased over time regardless of the recurrent seasons, while fungal communities were less affected by prolonged water limitation. Under low soil water contents, desiccation‐tolerant groups outcompeted less adapted, and the lifestyle of prokaryotic taxa shifted from copiotrophic to oligotrophic. While the abundance of saprotrophic and ligninolytic groups increased alongside an accumulation of dead plant material, the abundance of symbiotic and nutrient‐cycling taxa decreased, likely impairing the development of the trees. Overall, prolonged episodes of drought appeared to continuously alter the structure of microbial communities, pointing to a potential loss of critical functions provided by the soil microbiome.
