The cultural semiotics of Jingshen and cognitive homeostasis

Abstract Sonesson’s vision of the diversity of meaning-generation coincides well with the purview of the cultural semiotics of Jingshen, in which semiotic inquiry is envisioned to improve mental capacity, the expansion of mental/cognitive space, and ultimately the liberation of human thinking. When embracing new epistemologies for cognitive semiotics, semiotic inquiry can work well as a form of art of thinking that has the potential to maintain “cognitive homeostasis”, the tendency towards a relatively stable equilibrium that can be maintained in the holistic flux of mind, vitality, and creativity. A plausible path to this equilibrium is through a balance between the left and right hemispheres, between analytical thinking and synthetic thinking. In this sense, what we are facing is essentially a problem of “ecology of cognition” or “ecological cognition”, that is, viewing cognition from an ecological perspective or considering cognition as a form of ecological activity. The focus of cognitive semiotics nowadays must transcend not only words or other external symbols, but even the traditional sense of “humanity” needs to be reconsidered.

An ecological inquiry into the identity formation of a novice TESOL research mentor: Critical autoethnographic narratives in focus

This study reports on the identity formation of the author as a novice research mentor of an independent research course for TESOL teachers over six months (from the course design to the first research submission). The data is collected from four critical autoethnographic narratives written by the author before, during, and after this period. The narratives were analysed thematically with an eye on the theoretical underpinning of the study, i.e. ecological perspective, in three ecological layers namely micro-, meso-, and macrosystem. The results revealed that the author’s identity construction was influenced by different factors such as ‘autonomy in mentoring’, ‘mediating mentorship’, or ‘academic recognition’ in three levels of educational ecology. The results of this study can motivate research mentors and teacher educators, specifically novice ones, to find some similarities with the ideas discussed in this research and to record their lived experiences as a tool for reflection.

Lentinula edodes substrate formulation using multilayer perceptron-genetic algorithm: a critical production checkpoint.

Shiitake (Lentinula edodes) is one of the most widely grown and consumed mushroom species worldwide. They are a potential source of food and medicine because they are rich in nutrients and contain various minerals, vitamins, essential macro- and micronutrients, and bioactive compounds. The reuse of agricultural and industrial residues is crucial from an ecological and economic perspective. In this study, the running length (RL) of L. edodes cultured on 64 substrate compositions obtained from different ratios of bagasse (B), wheat bran (WB), and beech sawdust (BS) was recorded at intervals of 5 days after cultivation until the 40th day. Multilayer perceptron-genetic algorithm (MLP-GA), multiple linear regression, stepwise regression, principal component regression, ordinary least squares regression, and partial least squares regression were used to predict and optimize the RL and running rate (RR) of L. edodes. The statistical values showed higher prediction accuracies of the MLP-GA models (92% and 97%, respectively) compared with those of the regression models (52% and 71%, respectively) for RL and RR. The high degree of fit between the forecasted and actual values of the RL and RR of L. edodes confirmed the superior performance of the developed MLP-GA models. An optimization analysis on the established MLP-GA models showed that a substrate containing 15.1% B, 45.1% WB, and 10.16% BS and a running time of 28 days and 10 h could result in the maximum L. edodes RL (10.69 cm). Moreover, the highest RR of L. edodes (0.44 cm d-1) could be obtained by a substrate containing 30.7% B, 90.4% WB, and 0.0% BS. MLP-GA was observed to be an effective method for predicting and consequently selecting the best substrate composition for the maximal RL and RR of L. edodes.

Integrating Environmental Sustainability into Macroeconomic Frameworks: The Eco-Keynesian Cross

The ecological transition hinges on ecological structural change, necessitating smart macroeconomic policies. Incorporating ecological considerations into macroeconomic modelling constitutes a pivotal area of inquiry that examines the nexus between environmental sustainability and economic expansion. This article proposes a macroeconomic modelling to establish a foundational analytical framework to address this challenge. Incorporating ecological considerations into macroeconomic modelling constitutes a pivotal area of inquiry that examines the nexus between environmental sustainability and economic expansion. Contributing to the post-Keynesian Ecological Macroeconomics field, this paper proposes an eco-Keynesian cross due to its simplicity and widespreadness for teaching macroeconomics to illustrate the macroeconomic perspective of green targets strategies in a closed economy. Green public and private investments have the potential to enhance output through the multiplier effect and improve environmental efficiency. However, these investments may also induce rebound effects, resulting in a net increase in pollution intensity within the economy. The model underscores the potential trade-off between social and environmental objectives, which an ecological perspective seeks to surmount by advocating for sustainable and inclusive industrial development.

Towards a Communication Ecology in the Life of Rural Senior Citizens: How Rural Public Spaces Influence Community Engagement

The dilemma of weak participation and non-participation of rural communities is a universal topic of global development. The rural public space is an important field for local residents to interact, communicate, and engage with each other, and is an important place for the sustainable development of rural areas. However, previous studies have neglected to understand the intrinsic connection between rural public space and community participation from the perspective of community communication ecology. Based on the concept of age-friendly communities, this study’s fieldwork in rural Shanghai, China, using the methodology of grounded theory, found that physical, social, and psychological factors all have an impact on community engagement among rural residents. Specifically, environmental quality, facility support, community networks, social participation, call to action, place attachment, spatial perception, and self-transformation are identified as the core elements that significantly influence community engagement among rural residents. This study further reveals that the multiple factors influencing community engagement among rural residents are complex and interdependent rather than operating independently. Spatial support, communicative triggers, and symbolic identification, respectively, operate at the technological level (physical–social factors), social level (social–psychological factors), and discursive level (psychological–physical factors) to promote community engagement among older adults in Chinese rural areas. Through this research, we hope to further the realization of rural civic engagement and the sustainability of local communities and to provide scholarly insights into the promotion of more equitable community life.

How to restore ecological impacts from wind energy? An assessment of Zhongying Wind Farm through MSPA-MCR model and circuit theory

The wind energy industry is developing rapidly in China with a maximum capacity worldwide. Meanwhile, the stability of the ecological network is challenged by extensive renewable energy expansion. There are still research deficiencies in wind farm ecological impacts at project scale from an ecological restoration perspective. It is of great necessity to monitor the ecological impacts with time going and explore ecological restoration strategies for wind power development. The research case of Zhongying Wind Farm is selected based on investigation and interviews regarding its ecological impact in the prior study. It employs a comparative methodology by comparing the ecological quality before and after the construction of Zhongying Wind Farm. Raw data from Landsat 8, the Digital Elevation Model (DEM), the Normalized Difference Vegetation Index (NDVI), and wind turbine statistics originating from open data platforms are analyzed and visually represented with ArcGIS. This paper establishes an ecological network based on morphological spatial pattern analysis (MSPA) and the Minimum Cumulative Resistance (MCR) model to quantify wind farms’ impacts on ecological corridors. The circuit theory and Pajek software are used to identify and categorize the ecological nodes into weak and obstacle points. The results reveal that ecological impacts on ecological corridors decay with distance, reflecting changes in length, connection strength and cumulative values of corridors. While the impacts on ecological nodes depend on nodes’ attributes: the number of weak points increased by 18.5 %, and obstacle points increased by 350 %, with their locations shifting from the edges of urban construction sites to the edges of wind farm. Differentiated strategies are proposed according to the impact magnitude of each ecological corridor and node: such as dynamic inspection mechanism, construction prohibition for protection; corridor structure and function recovering, stepping stones addition for restoration; buffer belts, warning radar, and monetary schemes for compensation. This research fills the gap of ecological impact assessment under the challenges of wind energy expansion. It helps to balance wind energy development and ecological restoration at the regional level.

Reconceptualising Barriers to Engagement with Climate Change

This paper contributes to the discourse on climate change by emphasising the imperative for inclusive engagement, particularly at the intersection of socio-economic challenges and climate impacts in Glasgow, Scotland. Despite recent shifts towards a ‘Just Transition’ and increased public engagement efforts, working-class voices remain marginalised. To address this gap, the paper first reviews existing literature on Climate Change Communication (CCC), examining some of the competing conceptualisations of barriers and public engagement and their policy implications, and more specifically, participatory policymaking and its role in engagement. Through doing so, the central debates of how public engagement with climate change ought to be pursued will be established, and to what degree this can be understood in the context of developing engagement with working-class people. Subsequently, it proposes a novel framework synthesising insights from Lorenzoni, Sutton, and Tobin utilising an ecological Marxist perspective that aims to address barriers to climate change engagement among the working class.

Why is ‘clean’ energy opposed? the resistances to geothermal energy projects in Turkey

This study focuses on the resistance to geothermal energy projects in the Aegean region in Turkey. It explores, drawing on the analysis of documents and the fieldwork conducted in four Aegean cities, why there is a widespread local resistance to geothermal energy, which is widely promoted as environmentally benign and renewable and, as such, critical for the low-carbon energy transition. Examining the resistance from a political ecology perspective, I show how the power/resistance nexus in the field of renewable energy is shaped in those contexts where authoritarianism, populism, and geographically specific forms of capital accumulation operate in and through each other. Specifically, I demonstrate that the formulation of geothermal policy and practices to perpetuate and consolidate the power of the authoritarian populist AKP government laid the groundwork for the generation of widespread resistances by threatening to create new environmental injustices and to deepen existing class, and gender inequalities. The study also shows that geothermal energy may be as destructive as fossil fuel-based energy when not planned, regulated, or monitored effectively. It is concluded therefore that the practice of grouping renewable energy sources in a single ‘clean energy’ category should be reconsidered.

Urban flooding and the resultant pollution: What French-speaking scientists make of it?

Flood damage has increased worldwide in recent decades with a concomitant increased risk of flood-induced pollution. From the perspective of urban political ecology, we ask whether scientists acknowledge flood-induced pollution as a problem and if so how they address it. Using a mixed-methods approach, we analyse 30 semi-structured interviews with researchers in France and Quebec. Our results show that flood pollution can be framed not only in terms of its impact on the environment and our societies, but also as a social representation that varies with the spatial context. The diversity of flood-induced pollution, whether in terms of materiality, visibility, or causation, highlights the undefined contours of flood pollution for the scientific community. We identify obstacles to the emergence of this problem in the scientific arena explained by the structuring of this arena, the vagueness of the term pollution, regulation, and individual and collective approaches to resilience. We argue that these obstacles can be overcome by considering pollution as a social construct and viewing cities in a metabolic framework.

Frames of agency in a school with poor indoor-air quality: A longitudinal composite narrative study

Problems with schools' indoor-air quality are common, and they can cause health problems to adolescents. However, no previous research has examined how adolescents make sense of such contaminated socio-material environments or what kinds of agency those environments afford. Taking an ecological psychology perspective informed by frame analysis, we analysed longitudinal focus group interviews with adolescents in a Finnish school with longstanding indoor-air problems. We constructed three composite first-person narratives that reflected different experiential frames, with corresponding forms and changes of agency. We found that our adolescents made sense of the same socio-material environment and its affordances in very different ways, and this process afforded them to develop many kinds of agency that changed over time.

Habitat quality on the edge of anthropogenic pressures: Predicting the impact of land use changes in the Brazilian Upper Paraguay river Basin

Landscape changes driven by anthropogenic activities often have negative impacts on ecosystems, jeopardizing the provision of vital services that sustain biotic elements and wildlife. Predicting the effects of such transformations is crucial for developing strategies to mitigate ecological damage. This study explores the interaction of land use changes and habitat quality estimates in the Upper Paraguay River Basin in Brazil, using the InVEST Habitat Quality model to estimate spatiotemporal landscape trends and evaluate the potential impact of land use policies for the future. Under a business-as-usual scenario by 2050, potential land use changes are simulated for shaping habitat quality, habitat degradation, and habitat rarity estimates as landscape proxies for biodiversity conservation. Results show an extensive expansion of pastures through deforestation, leading to progressive habitat degradation with a significant decay in the predicted and observed habitat quality. The habitat quality index estimates show a spatial decrease from 0.78 to 0.57 for the 1989–2050 period. The same trend is observed in protected areas for the period 2019–2050, with an increase of anthropogenic land use and a decrease of the habitat quality from 0.80 to 0.57 in conservation units, and from 0.75 to 0.53 in indigenous lands. For improved conservation outcomes, this work introduces new insights for shaping environmental actions that can be flagged as sustainable land management practices and ecological perspectives towards spatial pressures at different scales. Therefore, government institutions responsible for the protection of conservation units and indigenous communities can be informed about potential land use impacts on their territories. The findings suggest that incorporating additional scenario trends and climate-related variables could be a valuable direction for future studies to extend further the modelling approaches explored in this work.

Imbalance and Alienation: An Eco-Critical Interpretation of Shuggie Bain

Since its publication in 2020, Shuggie Bain, the debut novel by Scottish author Douglas Stuart, has attracted scholarly attention for its unique ecological perspective. Utilizing the theoretical framework of eco-criticism and drawing on the tripartite division of ecology proposed by Chinese scholar Lu Shuyuan, this paper provides an in-depth interpretation of the novel Shuggie Bain in three dimensions of natural ecology, social ecology, and spiritual ecology, aiming to reveal the ecological imbalance and human alienation in Glasgow, a major industrial city in Scotland during the 1980s. This interpretation will also provide readers with a new research perspective for analyzing Shuggie Bain, enhancing their understanding of the rich ecological implications of it.

Exploring Factors Influencing Recreational Experiences of Urban River Corridors Based on Social Media Data

River corridors, recognized as “blue–green infrastructure,” have become a crucial support system for urban sustainability in contemporary urbanized societies. Understanding the factors influencing the recreational experience along urban river corridors is paramount for enhancing visitors’ health and well-being. This study focuses on the Hutuo River Corridor in Shijiazhuang, China, collecting 3006 valid reviews from Dianping, a prominent review platform. We developed a text-based thematic model and conducted content analysis using this dataset. The main social (visiting time, duration of stay, motivation, safety, and visitors’ types and activities) and physical (natural elements, artificial facilities, maintenance and management, accessibility, distance, models of transportation, weather, and seasons) factors associated with recreational experiences were identified. We assessed visitor perceptions of urban river corridors and elucidated facilitators or barriers through textual content analysis in reviews. The results indicate the feasibility of employing social media data to study visitors’ recreational experiences along urban river corridors. This comprehensive exploration from a qualitative ecological perspective contributes valuable insights for urban planning and management. Moreover, the findings hold significant implications for understanding the usage patterns of river corridors in China and potentially in other countries.

EMI teachers’ emotion labour: capturing classroom, institutional and sociocultural ecologies

ABSTRACT Although English medium instruction (EMI) has received exponential growth of attention in recent years, the scope of research on EMI teachers is still limited, and even much less on their emotions. Drawing on an ecological perspective as the theoretical framework, we explored Iranian EMI teachers’ emotion labour across the classroom, institutional and sociocultural ecologies. Data were collected from narrative frames and semi-structured interviews. Data analysis revealed three themes in relation to Iranian EMI teachers’ emotion labour: (1) classroom ecology: student expectations as impeding effective content enactment, (2) institutional ecology: workload as a hurdle for investment in personal growth and (3) sociocultural ecology: low international collaborations complicating knowledge dissemination. The study shows that beyond their personal proclivities, Iranian EMI teachers face socio-educational challenges that not only complicate their pedagogical effectiveness, but also stop them from imagining the identity of global citizens within the community of EMI practitioners. We also provide implications for EMI teacher educators to draw on the study findings to run teacher education courses that tap EMI teachers’ emotions.

Moving towards an ecological management of overabundant ungulates: insights from wildlife-vehicle collisions and hunting bag data

Increasing abundance of large ungulates is raising human-wildlife impacts and the effectiveness of recreational hunting to reduce their population growth is increasingly questioned. We report on long-term trends (> 15 years) in wildlife-vehicle collisions (WVC) and hunting bags, and on associations between the annual growth rate of WVC and that of hunting bags for three ungulates – the wild boar, the red deer, and the roe deer – and the grey wolf in northwest Spain to evaluate the regulating capacity of recreational hunting at large spatial scale. Wildlife-vehicle collisions increased by 332% in 16 years and 91% of all traffic accidents were caused by collisions with these three ungulates. All ungulate species showed significant positive trends in WVC and hunting bags, but we did not observe a negative association between annual growth rate of hunting bags and that of WVC except for the wild boar. Results suggest that recreational hunting was unable to reduce ungulate population growth at the regional scale. There was no upward trend of vehicle collisions with wolves over the study period, possibly reflecting stable wolf populations. Natural mortality due to predation could be promoted through the protection of apex predators, but the lethal management of apex predators, often based on sociopolitical pressures rather than damage levels, can conflict with the strategy for mitigating ungulate impacts. Ungulate management needs to be reconsidered from an ecological perspective that integrates human management measures, including recreational hunting, based on the population dynamics and the recovery of predator–prey interactions by favoring the expansion of apex predators.

Ecological perspectives on female and male reproductive success with competition in two Serapias species.

The deceptive strategies by which orchids are pollinated and how these are capable of attracting pollinators remain understudied with regard to their implications for plant fitness. Despite their ecological importance, limited investigations have been conducted on sexual deception and shelter mimicry in orchid species, making this a compelling avenue in orchid biology research. To expand the knowledge of these reproductive mechanisms, we studied the pollination of Serapias lingua and S. parviflora in co-occurring and isolated sites in the Balearic Islands (Spain), further accentuated by the presence of a hybrid, indicating shared pollinators. We employed bagging and hand pollination experiments to examine the reproductive biology of the two species. Furthermore, we evaluated the influence of phenotypical and ecological factors on reproductive success, including biometric measurements, reproductive performance and neighbourhood diversity (co-flowering and pollinator communities). Reproductive mechanisms between these two orchid species exhibit substantial disparities. Serapias lingua relies primarily on insect-mediated pollination, while S. parviflora demonstrates self-reproduction capacity. Although events of open pollination are rare, hybridization occurs predominantly when S. lingua is the pollen donor. Fruit set in S. parviflora was positively correlated with plant height, while in S. lingua it was negatively associated with flower size. The coexistence of the two species positively affected pollinium removal in S. parviflora, but did not exert an influence on reproductive traits in S. lingua. Overall, biometric parameters were diminished in isolated compared with co-occurring sites. At the community level, the increased diversity of co-flowering species in the vicinity exhibited an inhibitory effect on pollinium removal in S. parviflora. Under a context of pollinator loss or phenological mismatch between pollinator presence and flowering, the selfing capacity of S. parviflora would guarantee reproduction whereas S. lingua survival would be compromised. Furthers studies are needed to assess the effects of phenotypical and ecological factors on reproductive success of S. lingua in pollinator-decline scenarios.

Habitat- and lifestyle-dependent structural and functional characteristics of viruses in mangrove wetlands of different functional zonings

Mangrove wetlands, as one of the natural ecosystems with the most ecological services, have garnered widespread attention about their microbial driven biogeochemical cycling. Urbanization have led to different spatial patterns of environmental conditions and microbial communities in mangroves. However, viruses, as the pivotal drivers of biogeochemical cycling in mangroves, remain inadequately explored in terms of how their ecological potential and complex interactions with host respond to functional zonings. To address this knowledge gap, we conducted a comprehensive investigation on the structural and functional properties of temperate and lytic viruses in mangrove wetlands from different functional zonings by jointly using high-throughput sequencing, prokaryotic and viral metagenomics. Multiple environmental factors were found to significantly influence the taxonomic and functional composition, as well as lysogen-lysis decision-making of mangrove viruses. Furthermore, enriched auxiliary metabolic genes (AMGs) involved in methane, nitrogen and sulfur metabolism, and heavy metal resistance were unveiled in mangrove viruses, whose community composition was closely related to lifestyle and host. The virus-host pairs with different lifestyles were also discovered to react to environmental changes in different ways, which provided an empirical evidence for how virus and bacteria dynamics were specific to viral lifestyles in nature. This study expands our comprehension of the intricate interactions among virus, prokaryotic host and the environment in mangrove wetlands from multiple perspectives, including viral lifestyles, virus-host interactions, and habitat dependence. Importantly, it provides a new ecological perspective on how mangrove viruses are adapted to the stress posed by urbanization.
