Published: July 2024

Purpose

This study strives to better understand resistance to chatbots in the banking sector. To achieve this, it proposes a model based on the paradigm of resistance to innovation and the complexity theory. In addition, it explores the role of gender in relation to chatbot resistance.

Design/methodology/approach

Data are collected in France using a snowball sampling technique. The sample is composed of 385 participants. FsQCA is used to identify all possible combinations of usage, value, risk, tradition and image barriers, as well as two gender conditions that predict resistance to chatbots.

Findings

The results reveal that the sample provides four possible solutions/combinations that may explain resistance to chatbots. These are: (i) a combination of usage, value, risk and tradition barriers, (ii) a combination of value, risk, tradition and image barriers, (iii) a combination of usage, value, risk and image barriers, along with the male gender and (iv) a combination of usage, value, tradition and image barriers, along with the female gender.

Research limitations/implications

This study provides valuable and straightforward theoretical and managerial implications. The proposed solutions suggest a deep understanding of chatbot resistance. Chatbot developers and marketers can highly benefit from these findings to enhance user acceptance.

Originality/value

In this study, barriers are envisioned within the larger context of innovation resistance. The interactions among barriers causing resistance to chatbots are examined through the lens of the complexity theory, while the data analysis employs the fsQCA approach. Furthermore, this study sheds light on the role of gender in explaining chatbot resistance in the banking sector.

Authors: Aryee Raphael
Published: July 2024

Purpose

Theory is an essential prerequisite in the development and maturation of any scholarly discipline. This study offers insight into theory development in reverse logistics (RL) studies, provides a synopsis of the theories employed in RL studies, and presents a comprehensive framework for choosing and applying theories in RL studies.

Design/methodology/approach

Using the systematic literature review approach, 265 various RL articles were analysed to discover the trend in using theories in RL studies and classify the individual theories employed. The analysis of the theoretical classification is presented to explain the type and frequency of the usage of theories.

Findings

The analysis discovered 52 specific theories from the sample. These theories were categorised under various categories: competitive, inventory, economic, decision, etc. The institutional, stakeholder, transaction cost economies, resource-based view, natural resource-based view, dynamic capability, agency and theory of planned behaviour were some of the key theories discovered. Finally, a comprehensive framework is provided to aid researchers in choosing and utilising theories.

Research limitations/implications

This study gives authors, reviewers and editors perspectives on utilising theories in RL studies. It will give them the impetus to develop theories in RL and limit the borrowing or extension of theories from other disciplines to RL studies.

Originality/value

To the best of the researcher's knowledge, this is the first attempt to comprehensively provide an anatomical perspective into theory usage in RL studies. Besides, this study's proposed framework for selecting and using theories is a novelty in the domain of RL.
Industry dynamism, SC risk management strategies and manufacturing plant performance
Authors: Deshpande Sujeet , Hudnurkar Manoj
Published: July 2024

Purpose

According to extant Supply Chain Risk Management (SCRM) literature, manufacturing firms must align their choice of SC bridging or buffering strategies with their operating environment to achieve high plant performance and minimize SC disruption impacts. However, very few empirical studies have examined the relative performance of these strategies in dynamic industry environments. This study aims to address this research gap. This study also seeks to supplement the limited empirical research that has examined the empirical relationships between a firm’s Supply Base Complexity (SBC), the likelihood of SC disruptions, and plant performance.

Design/methodology/approach

This study uses data from a cross-sectional survey of 202 manufacturing firms in India. The data is analyzed, and the study hypotheses are tested using PLS path modeling and SPSS PROCESS Macro.

Findings

The study shows that increased SBC leads to an increased frequency of SC disruptions with a negative impact on plant performance. The study also finds that the firm’s implementation of SC bridging or buffering strategies effectively moderates this performance impact. However, the study results do not support the hypothesis that industry dynamism moderates the relative effectiveness of SC bridging or buffering strategies in mitigating the negative impact of SC disruptions.

Originality/value

The study adds to the limited empirical research examining the SC disruption risk associated with SBC and the resulting performance impact. It addresses a gap in extant research by evaluating the efficacy of SC bridging and buffering strategies in mitigating this performance impact in dynamic industry environments.
More than survival. The meanings of cash transfers for the poor
Authors: Bertoluzza Giulio , Volturo Stella , Meo Antonella
Published: July 2024

Purpose

This article challenges the prevailing view that a minimum income for the poor is only relevant to basic needs. It contributes to the discussion on the meanings of money by specifically focusing on the Italian Citizenship Income scheme as a case study.

Design/methodology/approach

A qualitative research design was developed and implemented in four regions of northern Italy. The analysis is based on 131 in-depth interviews with minimum income recipients.

Findings

The empirical analysis shows that money transfer has various meanings. Four dimensions are identified: functional, relational, protective, and emancipatory. The first two are connected to spending, while the latter two are related to self-identity. Although the four dimensions may overlap and coexist in the daily lives of minimum income beneficiaries, they are distinguished for analytical purposes.

Originality/value

The article presents a comprehensive analysis of the multiple meanings that minimum income can have for beneficiaries; meanings which are often not explicitly addressed in social policy studies. It goes beyond the equally important consideration of material needs by adding other meaningful aspects. This approach makes a different way of looking at cash transfers possible, and it provides elements useful for the design and analysis of minimum income policies.
A comparative analysis of financial and nonfinancial rewards on work motivation and knowledge sharing in a postpandemic era
Authors: Vesal Mahdi , Gohary Ali , Rahmati Mohammad H.
Published: July 2024

Purpose

This paper aims to examine the impacts of financial and nonfinancial incentives on the development of employee work motivation and knowledge sharing in the postpandemic environment. The paper further investigates the role of transformational leadership as a moderator in enhancing the relationship between work motivation and knowledge sharing.

Design/methodology/approach

Adopting a quantitative approach, the study uses data collected from multiple informants, specifically senior managers, in Nepalese manufacturing and service business-to-business (B2B) firms.

Findings

Contrary to prior research, the results reveal that nonfinancial incentives have a stronger impact on work motivation in the postpandemic era. This enhanced work motivation, in turn, contributes to knowledge sharing, with transformational leadership further strengthening the relationship.

Practical implications

The findings suggest that B2B firms should consider moving toward leveraging nonfinancial incentives to motivate employees to develop knowledge sharing initiatives, especially in challenging circumstances such as those experienced in the postpandemic era. In addition, it is recommended that chief executive officers adopt a transformational leadership style to facilitate effective knowledge sharing within their firms.

Originality/value

In a developing economy and amid the challenges of the global pandemic, there has been limited research exploring the possible effects that financial and nonfinancial incentives could have on work motivation and knowledge sharing. This research bridges this gap by providing a fresh perspective on work motivation and knowledge management in B2B firms, contributing novel insights to the literature.
Combined effects of corrosion and fire on load-carrying response of hot-rolled steel reinforcement
Authors: Tariq Faraz
Published: July 2024

Purpose

Although separate studies on the influence of corrosion and fire exposure on the constitutive relationship of concrete and steel have been done, there is still a gap in knowledge on the influence of corrosion-temperature superimposition as nonlinear phenomenon. The current study is focused to investigate the response of hot-rolled steel bars subjected to corrosion-temperature superimposition.

Design/methodology/approach

Using the accelerated corrosion-impressed-current technique, hot-rolled specimens with different levels of corrosion were obtained. The hot-rolled rebars were first corroded to target levels such as (6, 12, 18, 24, 30 and 36%) and subsequently subjected to target temperatures (250 °C, 400 °C, 550 °C, 800 °C and 950 °C), before tensile tests were carried out to evaluate the residual mechanical response.

Findings

The outcomes showed a significant decline in the parameters governing the mechanical properties of steel reinforcement due to the combined damage due to corrosion and fire. Corroded reinforcement still showed ductile failure after exposure to fire. Moreover, the combined loss of load-bearing characteristics due to corrosion and fire has little influence on the modulus of elasticity. The outcomes of this investigation provide a theoretical database for the assessment of aged structural elements exposed to combination after exposure to fire.

Originality/value

The information concerning structural material's response to corrosion-temperature combined damage is still limited. The cover of the reinforcement is designed to safeguard the reinforcing bars from foreign agencies but is often damaged and spalled off due to corrosion, rendering the reinforcing bars directly exposed. The study aims at the experimental production of fire conditions in a corrosion-damaged infrastructure to cover the aforementioned research gap. The effects of corrosion being superimposed by exposure to elevated temperatures on key parameters affecting mechanical behavior were examined.

Highlights

Influence of corrosion-temperature superimposition on the mechanical properties of hot-rolled rebars.

Influence of corrosion-temperature superimposition on the macro and microstructure properties of hot-rolled rebars.

Influence of corrosion-temperature superimposition on stress-strain curves of hot-rolled rebars.

Influence of corrosion-temperature superimposition on tensile strength, modulus of elasticity and elongation of hot-rolled rebars.
Can regulated technological FOMO be used to enhance technology adoption at the bottom of the pyramid?
Authors: Joshi Rohit
Published: July 2024

Purpose

This study aims to focus on exploring the role of fear of missing out (FOMO) in the technology adoption context, whereby the bottom-of-the-pyramid (BOP) segment was studied to explore the factors responsible for the development of behavioural intentions (BI) to use unified payments interface (UPI), a disruptive technological phenomenon in the mobile payment systems field.

Design/methodology/approach

A mixed-method research approach involving both qualitative and quantitative methods was used. Initially, qualitative data obtained through interviews with UPI’s BOP users were subjected to thematic analysis, leading to the identification of eight factors and the construction of a conceptual model. Subsequently, 354 responses were gathered, and empirical analysis was conducted using structural equation modelling in AMOS 23.0.

Findings

Eight factors, including personal and social benefits, perceived security risk, socio-cultural influences, governmental influence, usability, psychological inertia, perceived value (PV) and FOMO, were discovered. The quantitative examination confirmed the validity of the conceptual model in the BOP context, explaining 51% of the variance in BI. FOMO and PV emerged as robust indicators of UPI adoption, with PV significantly regulating the impact of FOMO.

Originality/value

To the best of the author’s knowledge, this study is one of the first to explore what drives BOP users in an emerging economy to adopt UPI. The conceptual model it presents contributes to the advancement of technology adoption literature by incorporating FOMO alongside newly identified BOP-specific factors.
Health and social care leaders’ and employees’ perceptions of remote leadership and the associated factors
Authors: Terkamo-Moisio Anja , Paronen Elsa , Häggman-Laitila Arja , Lammintakanen Johanna
Published: July 2024

Purpose

The purpose of this study was to describe health and social care leaders’ and employees’ perceptions of remote leadership and the associated factors.

Design/methodology/approach

A total of 45 leaders and 177 employees from one Finnish health and social care organization completed an electronic questionnaire between October and November 2020. The questionnaire included questions related to background information, along with structured and open-ended questions addressing remote leadership and the associated factors. The collected quantitative data was analyzed with statistical methods, while inductive content analysis was used to analyze the qualitative data.

Findings

Remote leadership emerged as a developing form of leadership that was part of everyday life at a regional health and social care organization. However, it was also considered by some as a distanced and authoritarian form of leadership that reduced communication to a one-way flow of information. Remote leadership and digitalization in health and social care were generally perceived positively, especially among higher educated participants and those working mainly in a remote context. However, digitalization was also perceived as a burden and remote leadership as a source of uncertainty at work, especially among lower educated participants and those who worked mainly in traditional contexts.

Originality/value

This study expands the little-researched area and provides insights that can be used to further develop remote leadership and the related education.
Unlocking the relationship between board of directors’ attributes and international diversification in Indian firms
Authors: Bhatia Aparna , Khurana Meenu
Published: July 2024

Purpose

The study aims to investigate the relationship between certain key attributes of the board of directors as their international experience, tenure, age, independence and size and internationalization strategies of firms in an emerging economy.

Design/methodology/approach

The study uses random effects panel Tobit regression on a data set of 418 Indian companies spanning over a time frame of nine years from fiscal year (F.Y.) 2009–2010 to F.Y. 2017–2018.

Findings

Board members substantially associate with internationalization choices of emerging economy firms. Specifically, board members with extensive international experience, shorter tenure, higher age, greater independence and larger board size are associated with high level of internationalization in these firms.

Research limitations/implications

The study advocates that Indian companies should focus on recruiting board members with international experience, periodically refreshing their boards, valuing wisdom and experience, adhering to regulatory requirements of independent directors and increase the number of board members to expand internationally. By following this, Indian companies can successfully expand into international markets.

Originality/value

The study’s originality lies in its focus on the role of board members in the internationalization strategy of emerging economy firms, which remains an under-researched area.

Authors: Sudhakaran Gargy , Prabhakaran Abhinesh , Booth Colin , Abbey Samuel , Mahamadu Abdul-Majeed , Georgakis Panagiotis , Pohle Maria
Published: July 2024

Purpose

In alignment with the European Union’s Vision Zero initiative to eliminate road fatalities by 2050, leveraging technological advancements becomes crucial for addressing the challenges of vulnerable road users (VRUs), and for mitigating the impact of human error. Despite increasing scholarly interest in applications of extended reality (XR), a research gap persists, particularly in the role of XR in transportation safety. Therefore, the aim of the study was to fill this gap through a systematic literature review to evaluate comprehensively the potential scope and practical applicability of XR technologies in enhancing the safety of VRUs.

Design/methodology/approach

A systematic review was undertaken, following PRISMA guidelines meticulously, in which 80 relevant articles from databases, such as Scopus and Science Direct, were identified and analysed.

Findings

The results of the analysis revealed the potential of XR beyond pedestrians and cyclists, and highlighted a lack of research about the impact of XR with regard to the personal traits or abilities of VRUs. The results of a thorough analysis confirmed the potential of XR as a promising solution for an approach to collaborative co-creation in addressing the safety challenges of VRUs. In addition, the integration of eye-tracking with virtual reality emerged as a promising innovation for enhancing the safety of vulnerable road users.

Research limitations/implications

Theoretical implications include enhancing the understanding of applications of XR in VRUs’ safety and providing insights into future research possibilities and methodological approaches. Valuable insights into search strategies and inclusion-exclusion criteria can guide future research methodologies.

Practical implications

Practically, the findings from the study offer insights to assist urban planners and transportation authorities in incorporating XR technologies effectively for VRUs safety. Identifying areas for further development of XR technology could inspire innovation and investment in solutions designed to meet the safety needs of VRUs, such as enhanced visualisation tools and immersive training simulations.

Originality/value

The findings of previous research underscore the vast potential of XR technologies within the built environment, yet their utilisation remains limited in the urban transport sector. The intricacies of urban traffic scenarios pose significant challenges for VRUs, making participation in mobility studies hazardous. Hence, it is crucial to explore the scope of emerging technologies in addressing VRUs issues as a pre-requisite for establishing comprehensive safety measures.

Authors: Garg Shubham , Narwal Karam Pal , Kumar Sanjeev
Published: July 2024

Purpose

In the recent few decades, there has been a rampant increase in the demand of sustainable food products around the world because of high cognizance of consumers toward environment and health. Asian countries, especially India and China, are also expecting a tremendous boost in the domestic demand for organic food products in the upcoming few years. Therefore, it becomes pertinent to explore the factors affecting the purchase intention behavior of organic food items, especially in emerging economies, i.e. India. Hence, the paper aims to explore the factors driving the purchase decision of organic consumers by collecting data set from 603 organic food item consumers in India.

Design/methodology/approach

The study has applied advanced statistical tools, i.e. structural equation modeling, Harman’s single factor test and other statistical measures, to analyze the collected research data.

Findings

The results posit that consumers’ purchase intention has a favorable impact on health aspects; trustworthiness; social innovativeness; functional value; subjective norms and organic product knowledge. Moreover, the result explicates that health consciousness and trustworthiness are vital predictors of organic food purchase intention.

Practical implications

The findings may assist the producers, processors, marketers, policymakers and regulators in devising appropriate policies and strategies for comprehending the complex phenomenon of organic consumers’ purchase behavior.

Originality/value

To the best of the authors’ knowledge, this is the first study to explore the drivers of purchase intention of organic food items by collecting data from well-defined consumers of organic food items in India.
Smart adaptive technologies for intelligent transportation systems (ITS): efficient design through BIM integration
Authors: Kuol Abraham , Gharehbaghi Koorosh , Farnes Ken , Tee Kong Fah , McManus Kerry
Published: July 2024

Purpose

While efficient design in engineering projects is crucial, this paper aims to examine the integration of Building Information Modeling (BIM) into railway Intelligent Transportation Systems (ITS). The paper provides some key understanding of integrating BIM and ITS to improve the efficiency of railway infrastructure projects.

Design/methodology/approach

An in-depth qualitative analysis of three ITS case studies was conducted to understand BIM’s global impact and benefits in railway infrastructure projects. While case study one investigated the Crossrail (UK), the other two case studies were TUC Rail (Belgium) and the Intercity railway network (Norway).

Findings

The findings include the specific benefits of BIM, regarding the railway infrastructure. The result indicated that BIM benefits were consistently the same across all case studies. Although Case study 1 was the only one that boasts a high reduction in waste and reworks, all of the case studies showed less rework and delays due to BIM. The results indicated that the advantages of BIM for such projects are cost optimization, reduction in waste, rework and lessening delays. Subsequently, this leads to the ease and efficiency with which structures and railways can be built. The outcomes can ultimately assist transportation planners in better planning and managing railway projects.

Practical implications

This study proposes the integration of BIM into railway projects as a part of their ITS. The BIM integration into railway projects as a part of their ITS fits within the overall planning to handover phases. Specifically, the BIM integration improves the design process of typical railway projects. Thus, the most significant advantage of BIM for railway projects is to further improve their design process leading to a higher degree of constructability.

Originality/value

Railway infrastructure performs a major role in economic and regional development. The complexity of railway projects continues to increase as the need for more railway infrastructure is on the rise globally. BIM is proving to be an effective tool for improving the efficiency of railway infrastructure projects. As the utilization of BIM is intensifying, the railway industry can further exploit BIM to improve project delivery adeptness by offering greater collaboration leading to efficient design processes. As a result, the understanding of BIM for horizontal projects such as railway infrastructure on a global scale is a substantial exercise that this research aims to respond to.
Cross‐sectional study using the University of California, Los Angeles, Scleroderma Clinical Trials Consortium Gastrointestinal Tract Instrument 2.0 (UCLA SCTC GIT 2.0) for gastrointestinal disorders of systemic sclerosis
Authors: Hisada Satoko , Takeuchi Saki , Tozawa Takahisa , Yamada Yoshihiro , Ito Yumi , Kodera Masanari
Published: July 2024

This study aimed to identify severe gastrointestinal ailments in patients with systemic sclerosis (SSc), investigate the role of antibodies in gastrointestinal disorders, and explore the relationship between limited cutaneous SSc (lcSSc) and diffuse cutaneous SSc (dcSSc) in terms of gastrointestinal involvement and its association with skin stiffness. We used the University of California, Los Angeles, Scleroderma Clinical Trials Consortium Gastrointestinal Tract Instrument 2.0 (UCLA SCTC GIT 2.0) questionnaire to assess gastrointestinal disturbances in 100 patients with SSc. Gastrointestinal impairment was categorized into three levels: absence of or minor symptoms, moderate symptoms, and severe symptoms, as indicated by the total gastrointestinal tract (GIT) score. Comparing 27 patients with dcSSc and 73 patients with lcSSc, severe gastrointestinal disturbances were found in 7.4% of patients with dcSSc and 4.1% of patients with lcSSc. A total of 18.0% of anticentromere antibody (ACA)–positive patients exhibited moderate to severe symptoms, while 9.1% of antitopoisomerase 1 antibody–positive patients displayed similar symptoms. The average disease duration in patients with severe symptoms was 15.0 years, in those with moderate symptoms was 10.3 years, and in those who were symptom‐free or mildly affected was 8.5 years. Among 16 patients with moderate to severe gastrointestinal disorders, a positive correlation was observed between the modified Rodnan skin thickness score (mRSS) and total GIT score. In addition, a positive correlation was identified between fecal incontinence and mRSS, with weaker correlations for reflux and bloating symptoms. Patients with gastrointestinal disorders showed a tendency to worsen over time, particularly in ACA‐positive patients with dcSSc. Furthermore, a correlation was observed between mRSS and fecal incontinence, reflux, and abdominal bloating in patients with moderate to severe gastrointestinal disturbances.

Published: July 2024

In various animal species conspecifics aggregate at sleeping sites. Such aggregations can act as information centres where individuals acquire up‐to‐date knowledge about their environment. In some species, communal sleeping sites comprise individuals from multiple groups, where each group maintains stable membership over time.

We used GPS tracking to simultaneously record group movement in a population of wild vulturine guineafowl (Acryllium vulturinum) to investigate whether communal sleeping sites can facilitate the transfer of information among individuals across distinct groups. These birds live in large and stable groups that move both together and apart, often forming communal roosts containing up to five groups.

We first test whether roosts provide the opportunity for individuals to acquire information from members of other groups by examining the spatial organization at roosts. The GPS data reveal that groups intermix, thereby providing an opportunity for individuals to acquire out‐group information.

We next conduct a field experiment to test whether naïve groups can locate novel food patches when co‐roosting with knowledgeable groups. We find that co‐roosting substantially increases the chances for the members of a naïve group to discover a patch known to individuals from other groups at the shared roost. Further, we find that the discovery of food patches by naïve groups subsequently shapes their space use and inter‐group associations. We also draw on our long‐term tracking to provide examples that demonstrate natural cases where communal roosting has preceded large‐scale multi‐group collective movements that extend into areas beyond the groups' normal ranges.

Our findings support the extension of the information centre hypothesis to communal sleeping sites that consist of distinct social groups.

Published: July 2024

Pollinators are essential for maintaining sustainable crop production, while the decline of pollinators is a widespread concern. Agricultural intensification is one of the primary drivers of the decline of insect pollinators. Agricultural intensification usually involves a decreasing of non‐crop semi‐natural habitat and an increasing of pesticide exposure for pollinators. However, causal links between agricultural intensification, increased pesticide exposure, and reduced pollinator's food sources and pollinator diversity remain underexplored.

We assessed pollinator diversity across a landscape gradient where the proportion of rice ranged from 11% to 85% in South China. We placed honeybee (Apis mellifera) and mason bee (Osmia excavata) in these landscapes and investigated pesticide exposure in honeybee foragers and pollen, and in mason bee pollen and nesting materials. We also assessed the acquisition of food by mason bees.

We found a higher frequency of pesticide detection in honeybee foragers and honeybee pollen samples in areas with a higher proportion of rice fields. There was a strong positive relationship between mason bee food acquisition and the proportion of semi‐natural habitats, while no significant effects of pesticide exposure on pollinator diversity were found in addition to the effect of semi‐natural habitat.

Synthesis and applications: Our results suggest that pollinator communities could be at an increased risk of pesticide exposure due to intensified agriculture, while the negative impact on pollinator diversity mainly results from the loss of habitat and/or reduced food sources. This study highlights the importance of conserving semi‐natural habitat to mitigate the causes of decline in pollinator diversity. We also recommend long‐term, multi‐year studies to further understand the mechanisms behind the loss of pollinators in farming landscapes.
Why are plant communities stable? Disentangling the role of dominance, asynchrony and averaging effect following realistic species loss scenario
Authors: Lisner Aleš , Segrestin Jules , Konečná Marie , Blažek Petr , Janíková Eva , Applová Markéta , Švancárová Tereza , Lepš Jan
Published: July 2024

A growing number of studies have demonstrated that biodiversity is a strong and positive predictor of ecosystem temporal stability by simultaneously affecting multiple underlying mechanisms of stability, that is dominance, asynchrony and averaging effects. However, to date, no study has disentangled the relative role of these key mechanisms of stability in biodiversity experiments.

We created a species richness gradient by mimicking a loss of rare species and assessed the role of species richness on community stability and, more importantly, quantified the relative role of three stabilizing mechanisms, that is dominance (stabilization due to stable dominants compared to the rest of the species in the community), asynchrony (stabilization due to temporal asynchrony between species), and averaging effects (pure effect of diversity) on community stability across a species richness gradient.

We found that extreme species loss negatively impacted community stability, but just three species were enough to stabilize biomass production to a level similar to highly diverse communities. However, the similar stability of communities resulted from differing contributions from each stabilizing mechanism, depending on the community diversity. Since less abundant species were more temporally variable, species loss stabilized the populations of the remaining species. The loss of rare and subordinate species reduced the dominance and averaging effects, but increased the asynchrony effect. Hence, the asynchrony effect played a major role in the stability of species poor communities, while the averaging effect drove most of the stability of species rich communities. Overall, dominance played only a minor role, accounting for 5%–15% of the stabilization, while asynchrony and averaging effects were dominating forces contributing to ~85%–95% of the total stabilization.

Synthesis. This study highlights the importance of biodiversity and roles of dominant and rare species for long‐term community stability and, for the first time, disentangles relative roles of dominance effect, asynchrony and averaging effect on community stability in a real‐world biodiversity experiment.
Arbuscular mycorrhizal communities respond to nutrient enrichment and plant invasion in phosphorus‐limited eucalypt woodlands
Authors: Albornoz Felipe E. , Prober Suzanne M. , Bissett Andrew , Tibbett Mark , Standish Rachel J.
Published: July 2024

Arbuscular mycorrhizal fungi (AMF) facilitate ecosystem functioning through provision of plant hosts with phosphorus (P), especially where soil P is limiting. Changes in soil nutrient regimes are expected to impact AMF, but the direction of the impact may depend on context. We predicted that nitrogen (N)‐only enrichment promotes plant invasions and exacerbates their P limitation, increasing the utility of AMF and promoting AMF diversity. We expected that enrichment with N, P and other nutrients similarly promotes plant invasions, but decreases the benefit and diversity of AMF because P is readily available for both native and exotic plants.

We tested these hypotheses in eucalypt woodlands of south‐western Australia, that occur on soils naturally low in P. We evaluated AMF communities within three modified ground‐layer states representing different types of nutrient enrichment and associated plant invasions. We compared these modified states to near‐natural reference woodlands.

AMF richness varied across ground‐layer states. The moderately invaded/N‐enriched state showed the highest AMF richness, while the highly invaded/NP‐enriched state showed the lowest AMF richness. The reference state and the weakly invaded/enriched state were intermediate. AMF richness and colonisation were higher in roots of exotic than native plant species.

AMF community composition differed among ground‐layer states, with the highly invaded/NP‐enriched state being most distinct. Distinctions among states were often driven by family‐level patterns. Reference and moderately invaded/N‐enriched states each supported distinct groups of zero‐radius operational taxonomic units (zOTUs) in Acaulosporaceae, Gigasporaceae and Glomeraceae, whereas Gigasporaceae and Glomeraceae were nearly absent from the highly invaded/NP‐enriched state. Further, Diversisporaceae and Glomeraceae were most diverse in the moderately invaded/N‐enriched state.

Synthesis. Both the nature of soil nutrient enrichment and plant provenance matter for AMF. N‐only enrichment of low‐P soils increased AMF richness, likely due to the introduction of AMF‐dependent exotic plant species and exacerbation of their P limitation. In contrast, multi‐nutrient enrichment, decreased AMF richness potentially due to a decrease in host dependence on AMF, regardless of host provenance. The changes in AMF community composition with nutrient enrichment and plant invasion warrant further research into predicting the functional implications of these changes.
Power to the posers: Delsartean women, the law of correspondence and the classical male body
Authors: Snow K. Mitchell
Published: July 2024

In the late nineteenth century, female adherents of the Delsartean physical culture movement in the USA would perform statue poses as part of their training and public appearances, employing both male and female statues in their work. This article positions this practice within seventeenth‐ and eighteenth‐century historical trajectories of the visual, rhetorical and performing arts and the allegorical meanings that prior generations had mapped onto the bodies of these works of art. This article argues that the Delsartean ‘law of correspondence’ equating internal states with external expression allowed their statue posing to serve as a tacit statement of gender equality.
AGENCY AND POWER OF COASTAL COMMUNITIES: Assembling Micro Infrastructures as Everyday Resistance and Resilience in North Jakarta's Port
Authors: Talib Naimah Lutfi Abdullah
Published: July 2024

The rise of the global supply chain has intensified the circulation of goods and capital across the world. While the body of literature on the politics and political‐economy aspects of logistical expansion has grown, little attention has been given to understanding how coastal fishers’ communities interact with the ongoing development of mega infrastructure. I argue that it is essential to place spatial and temporal specificity at the centre of analysis to further understanding of everyday resistance and resilience. In this article, I use a case study of the Port development in Jakarta to argue that renegotiating and reworking space and place amid the development of the mega port is a form of nonviolent everyday resistance and resilience that operates under, but also against, the capitalist political‐economy configuration. I focus on everyday resistance, particularly Asef Bayat's concept of quiet encroachment, and resilience literature to demonstrate the development and contested usage of micro and temporary infrastructures, both at household and community levels, as a material example of how diverse groups in communities exercise their agency and power, and express everyday resistance and resilience differently. Through this article, I aim to contribute to the broader literature on a situated political urban ecology, particularly on everyday resistance and resilience in postcolonial urbanism.
Rewriting the climate story with young climate justice activists
Authors: Trott Carlie D.
Published: July 2024

Amidst intensifying climate breakdown and inadequate climate change education, young people are increasingly taking part in a global movement for climate justice. Young climate justice activists are disseminating stories of injustice and possibility intended to inform and activate their peers, parents, politicians, powerholders, and the public for sweeping systems‐level change. Using in‐depth interviews with 16 youth activists aged 15 to 17 from the United States, this study explored youths’ stories into activism, defined as the counterstories motivating youths’ initial and sustained engagement in the climate justice movement. Using reflexive thematic analysis, two interrelated thematic categories were generated: redefining the problem of climate breakdown and challenging dominant climate solutionism. First, activists spoke of questioning dominant, depoliticised discourses that regard climate change as a primarily scientific or environmental problem that adults are currently “solving” to prevent future harms. Youths’ counterstories emphasised that climate change is an issue of present‐day and future injustices perpetuated by inadequate action by today’s adult leaders. Second, youths’ counterstories emphasised the powerful role of young people in spurring societal transformation towards climate justice—an inherently political and radical project requiring systems change through collective action. The research draws upon and contributes to recent scholarship in children’s geographies and critical geographies of education, while responding to urgent calls for reimagining climate pedagogies with young people’s well‐being and political agency at the centre. By examining the counterstories employed by young activists, this research highlights storylines educators may mobilise to activate learners’ political imaginations and spur their active engagement in societal transformation.

To compare four a priori rival mediated pathways of frequent social media use, electronic nicotine delivery systems (ENDS) use and internalizing mental health (MH) problems across five waves of nationally representative data.

Design, setting and participants

This was a longitudinal study using data drawn from waves 2–5 (October 2014–November 2019) of the Population Assessment of Tobacco and Health Study, a nationally representative cohort study spanning approximately 5 years, conducted in the United States. The analytical sample of participants included those who were aged 12–14 years at wave 2 and who provided data in subsequent waves until wave 4.5 (n = 4627, 69.7% were White and 51.4% were male).

Measurements

Frequent social media use (several times a day), ENDS use (past 30‐day use) and internalizing MH problems (endorsed symptoms on four items in the past year) were dichotomized for analysis.

Findings

The weighted proportions of the three key variables increased over time. From wave 2 to wave 5, frequent social media use grew from 56.9 to 77.2%; internalizing MH problems from 18.9 to 29.0%; and ENDS use from 1.4 to 11.4%. In weighted logistic regressions using generalized linear mixed models with random effects, there was a significant within‐person association between frequent social media use at time t and greater ENDS use at t + 1 [adjusted odds ratio (aOR) = 1.87; 95% confidence interval (CI) = 1.47, 2.37] and worsened internalizing MH problems at t + 1 (aOR = 1.19; 95% CI = 1.04, 1.37). A model‐based causal mediation analysis and marginal structural models were fitted to estimate the average causal mediation effect. Among all four examined mediation pathways throughout the three constructs, partial mediation was observed, and all the pathways were significant for both boys and girls. Sex differences did not emerge in the examined prospective mediated pathways.

Conclusions

Among youth in the United States, frequent social media use appears to mediate the prospective association between experiencing internalizing mental health problems and using electronic nicotine delivery systems.

Background and aims

This is the first nation‐wide register study based on a total population sample measuring the gender‐specific incidences of chronic diseases and conditions among adults diagnosed with gambling disorder (GD).

Design, setting and participants

The study used aggregated data for 2011–22 retrieved from the Register of Primary Health Care visits, Care Register for Health Care and Care Register for Social Welfare, including specialized outpatient and inpatient health care, inpatient social care and institutional care and housing services with 24‐hour or part‐time assistance, set in mainland Finland. Participants comprised people aged 18–90+ years with GD diagnosis [corresponding to pathological gambling, International Classification of Diseases 10th revision (ICD‐10) code F63.0, n = 3605; men n = 2574, women n = 1031] and the general population (n = 4 374 192).

Measurements

Incidences of somatic diseases and psychiatric disorders were calculated for the people with diagnosed GD and for the general population, separately for women and men.

Findings

After standardizing for age, the incidence of each diagnostic group was systematically higher for people with GD compared with the general population, except for cancer. The highest standardized incidence ratio (SIR) values were for psychiatric disorders [SIR = 234.2; 95% confidence interval (CI) = 226.1–242.4], memory disorders (SIR = 172.1; 95% CI = 119.1–234.8), nervous system diseases (SIR = 162.8; 95% CI = 152.8–173.1), chronic respiratory diseases (SIR = 150.6; 95% CI = 137.6–164.2), diabetes (SIR = 141.4; 95% CI = 127.9–155.5) and digestive diseases (SIR = 134.5; 95% CI = 127.1–142.2).

Conclusions

In Finland, the incidence of chronic diseases and conditions among people with gambling disorder is higher compared with the general population, apart from cancer.

The Carpentarian Pseudantechinus (Pseudantechinus mimulus, Dasyuridae) is a little‐known, saxicolous dasyurid marsupial from the Mount Isa Inlier bioregion in Queensland (QLD) and the Gulf Coastal bioregion in the Northern Territory (NT), Australia. A paucity of targeted survey effort across broad swathes of potentially suitable habitat means that the species' distribution and habitat associations are uncertain. This study aimed to (1) refine the contemporary distribution of P. mimulus, (2) determine the landscape and floristic variables that may predict P. mimulus presence, and (3) assess the current conservation status of P. mimulus. We conducted camera trap surveys covering 631 camera stations at 227 independent sites over 4 years for a total of 28 767 trap‐nights throughout QLD and NT in known and predicted suitable habitat. Stepwise generalized linear models were used to test the effect of landscape and floristic predictors on P. mimulus presence. The species' contemporary distribution was assessed using a MAXENT species distribution model. We collated a database of 292 records of P. mimulus, including 111 recorded during this study, extending the species' known range in QLD. The proposed holotype location of the Mittiebah Range was surveyed twice during this study but P. mimulus was not recorded. Pseudantechinus mimulus had the highest probability of presence on most non‐northerly aspects on metamorphic landforms. Eleven plant taxa had a significant effect on P. mimulus presence. This study provides new evidence for landscape and floristic factors that help predict the presence of P. mimulus. Our results indicate the possibility of two disjunct populations, but large swathes of potential habitat still require additional effort to determine the species' true distribution. Our estimate for area of occupancy partially satisfies a threatened species listing; however, more focused research on population dynamics, trends in habitat quality, and landscape‐scale threats is necessary.
Shaming, stringency, and shirking: Evidence from food‐safety inspections
Authors: Bovay John
Published: July 2024

This paper examines the responses of chicken producers to public disclosure of quality information (or categorization) regarding Salmonella in chicken carcasses. Producers exert effort to attain better categorization and shirk when failing to meet the thresholds required for better categorization. Public disclosure reduces this shirking effect. However, some producers shirk even under public disclosure when the threshold for disclosure is too stringent. The results suggest that the most effective quality disclosure policies would either disclose continuous (noncategorical) information or impose fines or other sanctions on producers attaining the poorest quality.
