Published: February 2025

PurposeThis study examines the temporal dynamics of consumer attitudes, perceived value and purchase intentions toward green agricultural foods, addressing critical gaps in the literature on sustainable consumption behaviours. It emphasises the mediating role of perceived value and its evolution over time, offering insights into consumer decision-making processes.Design/methodology/approachA longitudinal design was adopted, collecting data through structured questionnaires from primary household food purchasers in northern Taiwan at baseline, three months and six months. Analytical techniques, including multiple regression, mediation analysis and repeated measures ANOVA, were employed to examine relationships and track changes over time.FindingsThe results reveal that consumer attitudes positively influence perceived value, which fully mediates the relationship with purchase intentions. Temporal analysis indicates significant increases in perceived value and purchase intentions over six months, demonstrating that sustained exposure to green agricultural foods reinforces consumer commitment and pro-environmental behaviours. Attitudes alone do not directly predict purchase intentions without the mediation of perceived value, highlighting the critical role of perceived benefits in driving long-term sustainable consumption.Practical implicationsThis study provides actionable insights for enhancing the perceived value of green agricultural foods. Businesses should prioritise health and environmental benefits, while policymakers can design campaigns and incentives to promote sustainable dietary habits, aligning with Sustainable Development Goal 12.Originality/valueBy exploring the mediating role of perceived value in transforming positive consumer attitudes into purchase intentions, this study highlights how perceived value, shaped by health and environmental benefits, drives consumer behaviour. These findings contribute valuable insights for enhancing market appeal and supporting sustainable food marketing strategies.
Logistic-Grey-Markov prediction model

Published: February 2025

PurposeIn this study, a novel grey combined model, termed the logistic-Grey-Markov model, is proposed. This model aims to construct a relation function between transition probabilities and residual errors and fully utilize the information from residual errors to calculate optimal transition probabilities for more accurate predictions.Design/methodology/approachTo address this issue, the logistic function is introduced and improved to accommodate different types of samples. Then the improved logistic function is applied to construct a relation function between transition probabilities and sample residual errors. Additionally, to obtain the optimal coefficients in the relation function, a least square objective function is constructed, and the Levenberg–Marquardt algorithm is employed. With these optimal coefficients, the relation function can fully utilize the information of residual errors and calculate the optimal transition probabilities.FindingsThe improved logistic function in the logistic-Grey-Markov model ensures that the information from sample residual errors is fully utilized and case studies demonstrate that the proposed logistic-Grey-Markov model can effectively improve the prediction accuracy.Originality/valueOne of the strengths of the Grey-Markov model is its ability to predict outcomes with small and highly volatile samples. However, the prediction accuracy is not ideal due to the information waste of residual errors, especially when only a small sample size is available. The proposed logistic-Grey-Markov model can fully utilize the information in residual errors to calculate the optimal transition probabilities and improve the accuracy of the Grey-Markov model.

Purpose
This paper aims to regulate the oil retention rate and tribological properties of pored polytetrafluoroethylene (PPTFE) using polyvinyl alcohol (PVA)-based oil gel.

Design/methodology/approach
PPTFE was first prepared by using citric acid (CA) as an efficient pore-making agent. Subsequently, PVA and chitosan solution was introduced into the pores and experienced a freezing-thawing process, forming PVA-based gels inside the pores. Then, the PPTFE/PVA composite was impregnated with polyethylene glycol 200 (PEG200), yielding an oil-impregnated PPTFE/PVA/PEG200 composite.

Findings
It was found that the oil-impregnated PPTFE/PVA/PEG200 composite exhibited advanced tribological properties than neat PTFE with reductions of 53% and 70% in coefficient of friction and wear rate, respectively.

Originality/value
This study shows an efficient strategy to regulate the tribological property of PTFE using a PVA-based oil-containing gel.

Published: February 2025

PurposeConsidering the panel data from 1984 to 2020, this study examines the impact of demographic structure (young age, working age and old age manpower) on financial development in 44 Sub-Saharan Africa (SSA) countries. Following the World Bank’s classification, the SSA region is sub-sampled into 21 low-income, 18 lower-middle-income and five upper-middle-income countries to separately study these groups, along with studying for the whole region in a panel.Design/methodology/approachDrawing from the literature, it incorporates economic growth, economic globalization and inflation as a set of control variables in the financial sector development function. This study employed PCSEs and FGLS regression methods along with applying the FMOLS test for results robustness.FindingsThe result of PCSEs and FGLS evidences an adverse impact of the young and old age population on financial development for the entire SSA region, low-income and lower- and middle-income countries, but the same is found to be positively related to financial development in the upper- and middle-income countries. We observed varying effects of economic growth, economic globalization and inflation for different groups within the SSA region.Originality/valueFrom the policy perspective, it suggests that policymakers of the groups of low-income and lower-middle-income countries need to scrutinize the adverse effects of the young and old-age populations on financial sector development and should also be taken seriously in the formulation of their long-term financial development policies.

Published: February 2025

PurposeResidents’ understanding of the development and promotion of dark tourism cannot be universally assumed due to cultural and traditional disparities across different geographical regions. Using the social exchange theory (SET) and the cognitive appraisal theory (CAT) as the theoretical baseline for exploring the residents’ cultural perception of dark tourism development and promotion. The purpose of this study is twofold: first, to comprehend the residents’ perspectives about the meaning, values and cultural interpretation of dark tourism; second, to explore the residents’ attitudes from both an emotional and economic interface to dark tourism development and promotion in their community.Design/methodology/approachUsing a qualitative approach with purposive and snowball sampling strategies, 25 semi-structured interviews were conducted with residents or natives of the Jesse community, selected from both within and outside the community.FindingsOur research revealed that the residents’ emotions about the fire disaster transcend the prospect of economic empowerment the dark tourism concept could bring to the community. Besides, the respondents struggled to understand the meanings of dark tourism, but the younger respondents tended to welcome the idea more than the older ones.Practical implicationsThe study findings emphasized the importance of stakeholders in engaging the residents in designing and managing community tourism initiatives. This will prevent conflict with cultural traditions and ensure tourism sustainability.Originality/valueA novel study using the SET and CAT models to examine community perspectives on dark tourism from sub-Sahara Africa, providing an alternative viewpoint to Western interpretations and representation.
Abundance and reproduction behavior data for waterbirds (Anatidae, Rallidae, Charadriiforms, Podicipediforms) breeding in European France based on a probability sampling design

Published: February 2025

AbstractAppropriate management of wildlife requires sound knowledge and high‐quality data about species distributions, abundance, and trends in numbers. From a legal standpoint, Article 12 of the European “Birds” Directive requires Member States to report on breeding populations sizes. Acquiring such data is difficult owing to the wide distribution of most species and the multispecies nature of surveys. We relied on a stratified two‐stage spatial sampling design to assess breeding population size of waterbirds in European France. The data come from 2428 grid cells of 500 m × 500 m surveyed by territory or spot mapping three times at one‐month interval between 15 March and 15 June during the springs of 2021 or 2022. Individual bird location within each grid cell and their breeding behavior were recorded. A total of 6938 grid cell visits were undertaken, yielding 64,731 observations accounting for 132,292 individuals. These data are primarily aimed to assess the breeding population size of the 25 most common waterbirds (the population size estimates will be presented in a future article). However, because the location and time of observation of all individuals, as well as their behavior, are recorded, questions such as intra‐ and interspecific distribution rules, or habitat selection processes, can be addressed with this dataset too. As observers were also incited to record all other species among Anatidae, Rallidae, Charadriiforms and Podicipediforms, this dataset also provides robust original data on exotic and rare birds.

Through the eyes of the child: Children's experiences of family therapy in Malta
Authors: Abdilla Tivona Vella , Scerri Clarissa Sammut 
Published: February 2025

AbstractThis study explored children's experiences of family therapy. A mosaic approach with reflexive thematic analysis was used as the guiding methodology. The participants comprised seven children between the ages of six and 11 years. Rich data was gathered through child‐led tours, photographs of the therapy space, interviews and creative sessions with children plus interviews with five parents and four therapists. The findings indicate that the children considered family therapy to be an overall positive experience, thanks to the therapists, creative play‐based approaches and a therapy space that catered for them. Prior to starting therapy, children require more information about therapy to feel at ease. Creative approaches, together with caregivers' involvement, were identified as essential therapeutic tools with which to engage children in talk and play. Children's increased agency throughout the termination process is also essential. Suggestions for practice include a pre‐therapy booklet, using creative techniques as a primary tool when working with children, and ensuring an adequate therapy space. Suggestions for training include therapeutic skill development relating to working with children. Suggestions for future research are also made. This study's strength is that it highlights and spotlights children's perspectives.
‘Staging’ divinatory economic performances: Comparing startup and MLM cryptocurrency projects
Authors: Yogarajah Yathukulan 
Published: February 2025

This article offers ‘stages’, an original device, to sharpen the focus on a particular divinatory economic performance: the folding of imagined profitable futures into the present to create the impression that profitable futures are imminent or already realized. Drawing on ethnographic material from the startup and multi‐level marketing (MLM) cryptocurrency sectors, and utilizing ‘stages’ as a concept/pun – in the spatial and temporal sense – I show how economic performances must be ‘staged’ to convince people to invest. ‘Staging’ economic performances leads to creating a physical space of heightened excitement, expertise, and a temporal period that is experienced as urgent where one must think in an innovative way to bring about a profitable future. Under these conditions, ‘stages’ reveals how the line between a legitimate and an illegitimate project becomes indistinguishable to those on the ground. Doing your ‘due diligence’ to discern between the two is anything but straightforward. Despite claims by Euro‐American financial elites that startups and MLMs are polar opposites, this article demonstrates their striking similarity. More broadly, ‘stages’ reveals how economic performances gain efficacy, travel beyond specific sites, and come to act on people.
BLOOMBERG'S GLOBAL MAYORALTY: Philanthropy and the ‘Crisis of Capacity’ in City Government
Authors: Baker Tom , Sisson Alistair , McGuirk Pauline , Dowling Robyn , Maalsen Sophia 
Published: February 2025

AbstractBloomberg Philanthropies—the philanthropic organization of multibillionaire, CEO and former mayor of New York City, Michael Bloomberg—has become a palpably influential node in global networks of urban policy knowledge generation and mobility. This article examines the formative conditions, scope and operations of Bloomberg's philanthropically funded complex of urban policy influence. It begins by outlining Bloomberg Philanthropies' ecosystem of urban initiatives, which offer funding, technical support and entry into communities of practice for city government partners. It then traces the styling of Bloomberg's New York City mayoralty into a symbol‐turned‐model of effective administration and its alignment with Bloomberg Philanthropies' efforts to address the ‘crisis of capacity’ in city government. From there, the article analyses the formation of partnerships between Bloomberg Philanthropies and city governments. We show how Bloomberg Philanthropies occupies a powerful meta‐governmental position: as a city‐administration‐at‐large, it orchestrates a global‐institutional field that promotes and resources the implementation of technocratic, superficially pre‐political ‘best process’. But its relevance depends on harmonizing its agenda with the current desires and practical possibilities of city government. We argue that these asymmetric but interdependent relationships are important for understanding Bloomberg's global mayoralty and the general practice of philanthropic meta‐governance it exemplifies.

Published: February 2025

AbstractThis collaborative essay provides a methodological reflection and a list of recommendations on the opportunities, uncertainties and limitations faced when researching state spaces in India, Mexico and Kenya. Drawing on recent fieldwork across these countries, we illuminate the complexities and challenges inherent in studying state institutions and their roles in territorial governance and urban management. Our analysis is informed by 12 months of combined remote and in‐person research, during which we employed ethnographic immersion and in‐depth interviews to explore the interplay between digitalization and state power. We offer collective reflections along three main lines. First, we address the elusive nature of the state, highlighting the challenges of gaining trust from elite government officers and the significance of engaging with nonstate actors who mediate relationships between citizens and bureaucratic entities. Second, we underscore the importance of critically reflecting on the researcher's positionality and identity, particularly when working in culturally unfamiliar settings. Third, we advocate for the value of maintaining openness to multidisciplinary dialog and emphasize the importance of engaging with anticolonial and feminist methodological approaches. We believe these insights and lessons will be valuable to other scholars and practitioners investigating the dynamics of state power in the digital age.
High‐resolution Geochemistry in the Lucaogou Formation, Junggar Basin: An Assessment of Heterogeneous Shale Resources
Authors: SUN Shijie , ZHANG Bin , WANG Xiaomei , TIAN Hua , ZHANG Shuichang , HOU Guiting 
Published: February 2025

AbstractControlled by fluctuating paleoclimates and sedimentary environments, the organic and inorganic features of the Lucaogou Formation exhibit strong heterogeneity in the vertical profile, challenging conventional geological interpretation. To elucidate the possible influence of heterogeneity on resource evaluation, a high‐resolution sampling approach was applied to an 86.2 cm long core from the Lucaogou Formation of the Jimsar sag in the Junggar Basin. 86 sets of samples were micro‐drilled from the core and subjected to comparative Rock‐Eval pyrolysis. Following the classical guidelines, the organic abundance, kerogen type, and maturity of source rocks were exhaustively analyzed. Experimental results revealed that organic richness and composition vary significantly under different sedimentary backgrounds, which in turn leads to differential hydrocarbon generation. The combination of hydrocarbon generation, transport, and expulsion results in peculiar patterns for hydrocarbon accumulation in the Lucaogou Formation. Laminated shales in the Lucaogou Formation serve as both hydrocarbon source rocks and reservoirs, with laminae being migration pathways. Organic‐rich dolomites in the Lucaogou Formation have a considerable hydrocarbon‐generating capacity and present the characteristics of self‐generation and self‐storage. However, massive mudstones act purely as hydrocarbon source rocks.
Hydrothermal Control by Deep Hidden Faults on Geothermal Systems in Sedimentary Basins: A Case Study of the Cangdong Fault in the North China Basin

Published: February 2025

AbstractLarge basins are currently the global focus for geothermal development, with their hydrothermal system being controlled by a variety of factors, such as basement relief and fracture development. Donglihu is located at the north of the Cangxian uplift in the North China Basin, the concentrated geothermal resource development zone in North China. This study systematically collects temperature logging data and long‐term dynamic monitoring of water level and water quality as well as group well tracer test data carried out in this area in recent years, on the basis of which the hydrothermal controlling role of the deep hidden faults is systematically analyzed. The results show that the Cangdong fault communicates with different geothermal reservoirs in the shallow part and plays a specific role in the water‐heat channel of the local area. As a result, the high‐value area of the geothermal temperature gradient in the sedimentary layer of the Donglihu area is distributed around the Cangdong fault. The geothermal reservoir temperature of the Minghuazhen Formation within the influence of the fault is also significantly higher than the regional average, the hydraulic head of different geothermal reservoirs showing a consistent and synergistic trend. However, the water quality has been stable for many years without any apparent changes. This understanding has a particular significance for further deepening understanding of the geothermal genesis mechanism in sedimentary basins and guiding future geothermal exploration and development in the Donglihu area.
Petrogenesis and Metallogenic Implications of A‐type Granites in the Mid–Late Jurassic Dayishan Complex, Southern Hunan Province, South China

Published: February 2025

AbstractThe petrogenesis and genetic link to polymetallic mineralization of the granites in the Dayishan complex, southern Hunan province remain debated. Here, we present an integrated study on the petrology, zircon U‐Pb ages and whole‐rock geochemistry for this complex. Our findings indicate that the southern complex consists of (amphibole‐bearing) biotite granites and muscovite granites emplaced at 153–151 Ma, and the central and northern complex consists of two‐mica granites and tourmaline‐bearing muscovite granites, respectively with the former emplaced at 164 Ma and the latter at 150 Ma. The (amphibole‐bearing) biotite granites have SiO2 contents of 68.0–73.8 wt% and are enriched in alkalis and rare earth elements and depleted in Sr and Ba. They display Zr + Y + Ce + Nb > 350 ppm and 10000 × Ga/Al > 2.6 along with high zircon saturation temperatures (821–883°C). The two‐mica granites and (tourmaline‐bearing) muscovite granites have high SiO2 (74.4–77.3 wt%) and low Ga/Al, Zr + Nb + Ce + Y, K/Rb, Zr/Hf, and Nb/Ta along with low zircon saturation temperatures (709–817°C). Geochemical characteristics suggest that the (amphibole‐bearing) biotite granites are A‐type granites generated through shallow dehydration melting of early Paleozoic granitoids, and that the two‐mica granites and (tourmaline‐bearing) muscovite granites are fractionated A‐type granites produced through fractionation crystallization from the (amphibole‐bearing) biotite granites accompanied by fluid fractionation.
