Integration of Sustainable Development Goals into the Popalia Village Government Work Plan

This research aims to analyze the integration of SDG values into the Popalia Village Government Work Plan. This research uses an inductive qualitative analysis. Inductive analysis is an approach that begins with field facts, analyzes them based on relevant theories and arguments, and ultimately yields a conclusion. The results show that integrating the SDGs into the Popalia Village Government Work Plan has significantly contributed to village development. At the input stage, the active participation of the community in formulating work programs has reflected an inclusive approach that considers the needs and aspirations of the residents. In terms of outputs, tangible progress has been made in developing village infrastructure and health services, although some programs have yet to materialize fully. The impact of the Village Government Work Plan implementation has been positively felt by the community, especially in improving road infrastructure which enhances access and mobility. These results show that the integration of SDGs into the Popalia Village Government Work Plan has successfully created changes impacting the community’s quality of life. However, there are still challenges to overcome for more comprehensive success. Therefore, it is recommended that the Popalia Village Government intensify efforts to complete the unimplemented Village Government Work Plan programs, prioritizing initiatives that directly impact improving the community’s quality of life. Relevant community organizations are expected to support the village government through collaboration and mobilizing additional resources to ensure the sustainability and expansion of programs aligned with the SDGs. The villagers are also encouraged to actively participate in every stage of the Village Government Work Plan, from planning to evaluation, to ensure that the initiatives align with their needs and aspirations. Enhancing communication and coordination among all stakeholders is vital to overcoming existing challenges and maximizing the positive impact of integrating SDGs into the development of Popalia Village.

EXPRESS: Intersectionality in Marketing: a Paradigm for Understanding Understudied Consumers

Intersectionality remains largely underutilized within marketing. To address this gap, this paper synthesizes literature to provide tools for incorporating intersectionality into marketing research, including a framework for an intersectional marketing paradigm, a research design roadmap, a research agenda, and key takeaways for stakeholders. The definition of intersectionality focuses on three main components: 1) awareness and acknowledgment of overlapping (rather than isolated) social categories (e.g., gender, race, and class), 2) understanding of how differences in lived experiences at these intersections influence the marketplace, and 3) recognition of how power shapes these lived experiences. This article’s novel research design roadmap features concrete theoretical and methodological approaches for marketing researchers from various backgrounds to utilize intersectionality in solving marketing problems: conducting exploratory subsample analyses, developing intersectional theory and hypotheses, conducting inclusive literature reviews, collecting and reporting detailed demographics, sampling understudied populations, and carefully situating conclusions. The research agenda provides research questions for emerging topics at societal, organizational, and consumer levels. Engaging with intersectionality will help ensure that marketing remains socially relevant, develops diverse and inclusive theories, and more accurately reflects the lived experiences of understudied populations and communities.

Approaches to Metaphor: Cognitive-linguistic and Philosophical Perspectives

Metaphor has been a significant topic of discussion in several academic fields besides being extensively used in daily life. This article explores the interdisciplinary study of metaphor, a complex and connotative concept that has been the primary concern across various disciplines, including linguistics, philosophy, literature, and other humanities. The article presents multiperspective theories and metaphor analysis from the said disciplines to provide a more holistic understanding of metaphor. This includes analyzing metaphors in analytic philosophy and cognitive science, primarily focusing on the conceptual metaphor theory (CMT) developed by George Lakoff and Mark Johnson, complemented by analysis of the relevance theory, the blending theory, etc. While there are criticisms of CMT, it remains an influential theory in studying metaphor. The article also discusses the relevance theory, which suggests that using metaphors in speech can help achieve optimal relevancy, and the blending theory, which proposes that metaphors involve mapping elements from one mental space onto another to create a blended mental space that combines elements of both. This paper also addresses continental philosophers' usage or account of metaphor, from Kant to Derrida, in establishing their arguments. The essay then discusses and integrates ideas in metaphor studies from the perspectives of semantics and pragmatics. Finally, the article emphasizes the importance of bridging the gap between abstract conceptualizations and concrete linguistic expressions to gain a holistic understanding of metaphor.

The Influence of Different Gender Roles on the Formation of Attachment Types--An Analysis from an Evolutionary Psychology Perspective

The formation of attachment style is closely related to the development of children and the formation of intimate relationship, which is an important subject in the field of psychology. Some previous studies have found significant gender differences in insecure attachment and romantic attachment styles in adulthood. Women crave secure attachment more than men do. When it comes to romantic attachment, men are more avoidant, while women show more anxiety. This paper searches and collates relevant theories and studies, integrating the physiological and psychosocial factors that lead to this difference. In the course of biological evolution, survival, reproduction, and sexual division of labor provide reliable explanations for the differences in the physical, psychological, and social experiences of men and women. Despite the limitations of the current study and the controversy surrounding the findings, a study of cognition in gay and straight groups provides an important clue that an individual's overall cognitive pattern shows a higher correlation with cognitive gender than with biological sex. In future studies, the determination of "gender" from the previous biological sex to cognitive sex selection may help to obtain more accurate experimental results.

A pragmatics-cognitive approach to the opposition relations lexicalized in Chinese

Abstract Contrast, adversative and corrective can all be represented by er in Classical Chinese, but they are lexicalized respectively by er, danshi and ershi in Modern Chinese. The two lexicalization systems suggest that the opposition relations have commonalities as well as differences. In the framework of relevance theory and ‘three domains’, this study argues that the three opposition relations are in different cognitive domains, at different representational levels, and trigger different inferences, which accounts for their diverse lexicalizations in Modern Chinese. The opposition relations also have cognitive or metaphorical connections with each other, which justifies their unified actualization in Classical Chinese. The pragmatics-cognitive framework could also account for interlinguistic data.

Samawa Indigenous Marriage Law: Harmonizing Local Wisdom with National Law

This research aims to analyze and understand how integrating the Samawa tribe’s local wisdom in the practice of indigenous marriage can occur harmoniously and in alignment with Indonesia’s national law. This research uses an inductive qualitative analysis. Inductive analysis is an approach that begins with field facts, analyzes them based on relevant legal theories and arguments, and ultimately yields a conclusion. The results show that Samawa indigenous marriage law can integrate harmoniously with national law. This integration encompasses indigenous law, where the Tana Samawa Indigenous Institution is crucial in preserving local wisdom. The existence of this indigenous institution, regulated by Sumbawa Regency Regulation Number 10 of 2015, demonstrates the Regency Government’s commitment to integrating local wisdom with the national legal system. In indigenous marriage, this integration ensures that local wisdom remains valid under indigenous law and has legality under Law Number 1 of 1974. Challenges and obstacles in preserving Samawa indigenous marriage, require a comprehensive approach that includes education, documentation of customs, and promotion of local wisdom through modern technology. Therefore, it is recommended that the Tana Samawa Indigenous Institution continue to strengthen the preservation and development of local wisdom through comprehensive education programs and documentation, and forge more intensive cooperation with the Regency Government and educational institutions. The Department of Education and Culture of Sumbawa Regency is recommended to integrate local wisdom material into the formal and non-formal education curriculum, and support cultural preservation initiatives by providing adequate facilities and resources. Samawa indigenous people are recommended to actively participate in the preservation of customs, support programs run by the indigenous institution and government, and use modern technology to document and promote their traditions, ensuring that local wisdom values remain alive and respected in everyday life.

Research on the mechanism of consumer participation in value co-creation by innovative enterprises: An evolutionary game analysis framework.

The profound changes brought about by informatization and digitalization have given rise to the user-centered innovation concept, and value co-creation by enterprises has become an inevitable trend. It has become a pressing issue for scholars to analyze the mechanism of consumer participation in the value co-creation of innovative enterprises. In this paper, by establishing an evolutionary game model between consumers and innovative enterprises, we analyze in depth the mechanism of consumer participation in the value co-creation of innovative enterprises. The results show that the initial cooperation probability between consumers and innovative enterprises directly affects their strategic choices; the establishment of reward mechanisms makes consumers more inclined to choose active participation in value co-creation strategies; as the probability of non-cooperation between the two parties being reported increases, the probability of consumers and innovative enterprises choosing cooperation also increases. Studying the mechanism of consumer participation in the value co-creation of innovative enterprises has essential theoretical and practical significance for enterprises to achieve value creation, enhance competitiveness, and promote innovation. This study not only enriches and develops relevant theories but also provides guidance and support for the practice of enterprises, promoting sustainable development and successful co-creation.

Backstepping Synchronization Control for Four-dimensional Chaotic System Based on DNA Strand Displacement

Abstract Backstepping control is an important nonlinear control design method, which realizes the control of complex systems by constructing control law step by step, and has significant advantages for dealing with complex nonlinear systems. This article proposes a synchronization technique for four-dimensional chaotic systems using a combination of backstepping control method and DNA strand displacement technology. By relying on theoretical knowledge of DNA molecules, five basic chemical reaction modules such as trigger reaction, reference reaction, catalytic reaction, annihilation reaction and degradation reaction are given to construct a four-dimensional DNA chaotic system. On the basis of the relevant theory of chaotic dynamics, the constructed system is analyzed by Lyapunov exponent diagram and spectral entropy complexity algorithm, and the results come to the conclusion that the system reveals extremely complex and varied dynamic behaviors. Combining DNA strand displacement technology with backstepping control method, four controllers are developed to ensure that the trajectories of two homogeneous chaotic systems are synchronized. The numerical simulation results validate the feasibility and applicability of the proposed method. The method proposed in this paper may provide some references in the field of DNA molecular chaos synchronization control.

Study of the Dynamic Recrystallization Behavior of Mg-Gd-Y-Zn-Zr Alloy Based on Experiments and Cellular Automaton Simulation

The exploration of the relationship between process parameters and grain evolution during the thermal deformation of rare-earth magnesium alloys using simulation software has significant implications for enhancing research and development efficiency and advancing the large-scale engineering application of high-performance rare-earth magnesium alloys. Through single-pass hot compression experiments, this study obtained high-temperature flow stress curves for rare-earth magnesium alloys, analyzing the variation patterns of these curves and the softening mechanism of the materials. Drawing on physical metallurgical theories, such as the evolution of dislocation density during dynamic recrystallization, recrystallization nucleation, and grain growth, the authors of this paper establish a cellular automaton model to simulate the dynamic recrystallization process by tracking the sole internal variable—the evolution of dislocation density within cells. This model was developed through the secondary development of the DEFORM-3D finite element software. The results indicate that the model established in this study accurately simulates the evolution process of grain growth during heat treatment and the dynamic recrystallization microstructure during the thermal deformation of rare-earth magnesium alloys. The simulated results align well with relevant theories and metallographic experimental results, enabling the simulation of the dynamic recrystallization microstructure and grain size prediction during the deformation process of rare-earth magnesium alloys.

Evaluation of Sedimentary Characteristics of the Chang 9 Oil Layer Formation in the Yanchang Formation, Ordos Basin

Shallow-water deltas are a subject of sedimentary research and represent a significant target for oil and gas exploration. The Yanchang Formation of the Triassic in the Ordos Basin comprises numerous shallow-water delta blocks. This paper addresses the core issues pertaining to the sedimentary facies, sedimentary characteristics and sand body distribution of the Chang 9 oil layer formation of the Upper Triassic in the Ordos Basin. Guided by the relevant theories and methods of contemporary sedimentology and sedimentary geology, the reservoir characteristics are described and studied in detail through ordinary thin sections, cast thin sections, graphical representations of particle size and scanning electron microscopy experiments. The experimental results indicate that the porosity in the study area ranges from 3% to 12% and that the permeability is between 0 and 1.5 × 10−3 μm2, which is consistent with classification as an ultra-low-porosity and ultra-low-permeability reservoir. The Chang 9 sandstone is composed of feldspar sandstone and lithic feldspar sandstone. The average content of quartz is low, at less than 31%, while the average content of feldspar is high, at more than 34%. The average content of rock debris is between 10% and 20%. Therefore, the compositional maturity of the Chang 9 sand body is generally low. The particle size distribution exhibits a positive deviation, indicating that the sediments in the sand body are primarily coarse-grained components. The kurtosis of the particle size–frequency curve is observed to vary from flat to very sharp. The Chang 91 lake is classified as a shore shallow lake with basin subsidence and lake transgression. The Chang 9 period saw the development of the Chang 91 sedimentary facies into a semi-deep lake–deep lake environment. The vertical structural style of the Chang 9 oil layer formation in the basin can be roughly summarized into three basic structural types: the sedimentary structures observed in the area include box-shaped upward thinning, bell-shaped upward thinning and funnel-shaped upward thickening. The delta front area in Chang 9 is notable for its size and the prevalence of underwater distributary channel microfacies. The sand body distribution is stable, with sand layer thicknesses ranging from 15 to 30 m. The evaluation and summary of the sedimentary characteristics of the Chang 9 oil layer formation provide a geological basis for future exploration and development in the study area.

Cinema Narration as Oral Performance: DJ Afro and East African Media Practices

ABSTRACT This article examines cinema narration in Kenya, a practice that involves artists known as DJs working with audiences in specific socio-cultural contexts. This study uses ethnographic methods to analyse the work of one such practitioner, DJ Afro, and the reflections on his performance by two sets of audiences in Eldoret and Narok respectively. For this purpose, three Hindi films in DJ Afro’s repertoire have been selected: Magadheera (2009, directed by S. S. Rajamouli), Bullet Raja (2013, directed by Tigmanshu Dhulia) and Shadow (2013, directed by Meher Ramesh). The choice is influenced by DJ Afro’s audiences’ responses to his narration and to the genre of the films. The analysis of DJ Afro’s oral texts is done using relevant theories of oral performance and popular culture. The article makes two linked arguments. First, in Kenya, cinema narration has evolved into one of the genres of popular culture. Second, this performance may have been initially understood as translation of meaning for local audiences, but it also works as an oral narrative performance involving local performers and their audiences, and in this process the meanings produced are determined in relation to local texts and contexts.

Developing classroom ICT teaching techniques, principles and practice for teachers in rural Ghana without access to computers or internet: a framework based on literature review

PurposeThis paper aims to propose a conceptual framework for integrating information and communication technologies (ICT) into teaching practices for educators in rural Ghana lacking computer and internet access. Bridging the rural–urban digital divide is critical for equitable quality education. This research identifies distinct infrastructure, financial, human, and socio-cultural challenges of ICT adoption in underserved Ghanaian schools through an exhaustive literature review. The framework provides tailored strategies to empower teachers to leverage ICT for innovative pedagogy despite limitations. Ultimately, the goal is to offer pragmatic, evidence-based solutions to advance ICT-enabled instruction and digital equity in marginalized settings.Design/methodology/approachThis study utilizes a qualitative literature review methodology to develop a conceptual framework for ICT teaching techniques tailored to the rural Ghanaian context. Published empirical studies, theoretical papers, and reports focused on ICT education in developing countries, particularly sub-Saharan Africa, were systematically reviewed across multidisciplinary databases. Relevant theories and models, like TPACK and SAMR, were analyzed to determine appropriate modifications for the framework design. The proposed strategies emphasize affordable technologies, teacher training, localized content, and culturally relevant pedagogies selected based on evidence from literature to address the unique barriers and needs of the rural setting.FindingsThe literature review revealed profound infrastructure, financial, human, and socio-cultural barriers to ICT adoption in rural Ghanaian schools. These include lack of electricity, internet, hardware, and software alongside inadequate teacher training and support. The proposed conceptual framework offers solutions including leveraging low-cost technologies like mobile devices, prioritizing teacher professional development, developing localized digitally-enabled resources, and fostering community participation. Culturally relevant pedagogies are also emphasized. This tailored, evidence-based approach holds promise for enhancing ICT-enabled instruction and bridging digital divides to promote equitable quality education. Further findings will emerge through framework implementation and evaluation.Research limitations/implicationsThis conceptual framework requires implementation and evaluation to truly determine its impact and effectiveness in the intended rural Ghanaian context. As a literature review, primary data collection was not undertaken. Practical application of the framework in schools can yield direct insights through surveys, interviews, observations, and analysis of key educational outcomes pre and post-implementation. Comparisons with control groups may further illuminate its efficacy. Monitoring and adaptation over time is also essential. Ultimately, this research sets the foundation for praxis-oriented work transforming ICT integration in marginalized communities to advance digital equity and inclusion.Practical implicationsThis research provides an evidence-based, context-aware framework with pragmatic solutions to enhance ICT-enabled teaching and learning in underserved rural Ghanaian schools. It offers guidance to teachers, administrators, and policymakers on integrating technology despite infrastructure and resource constraints. The emphasis on cost-effective innovations, educator training, localized content, and community participation can inform planning and investments in ICT education. Broader applications include adapting the framework for other developing country contexts facing comparable challenges. Overall, this work promotes digital equity and quality education access, catalyzing social development and aligning with the UN Sustainable Development Goals.Social implicationsThis research highlights the urgent need to address digital divides exacerbating educational inequalities between rural and urban communities in Ghana. Lack of technology access and utilization in rural schools threatens to widen gaps in skills, capabilities, and opportunities for students. Strategic integration of ICT can promote social inclusion, cultivate digital literacy, and equip youth to participate in the global digital economy, thereby enhancing prospects. More broadly, advancing digital equity and ICT-enabled education empowers marginalized groups, fosters community empowerment, and drives progressive social change. This work underscores that localized, context-appropriate solutions are pivotal for promoting development and social justice.Originality/valueThis research fills a crucial gap by proposing a conceptual framework tailored specifically for integrating ICT in teaching practices in rural Ghanaian schools lacking digital access, responding to context-specific barriers and needs. While extensive literature examines ICT education models globally, few studies offer localized strategies for resource-constrained environments. This framework adapts established models based on a systematic literature review, emphasizing affordability, capacity building, and cultural relevance. By synthesizing evidence-based, pragmatic solutions to advance ICT-enabled instruction in marginalized settings, this work provides a valuable foundation for praxis transforming rural education. The localization approach could inform frameworks for other developing regions.

Research on the Driving Factors for the Application of Energy Performance Contracting in Public Institutions

Building energy efficiency in public institutions is crucial for achieving energy conservation and emissions reduction goals. The application of energy performance contracting (EPC) can effectively reduce energy consumption in these buildings and promote the development of the energy-saving service industry. However, there is a lack of initiative among public institutions to adopt EPC. This study aims to investigate the factors that drive the intention and behavior of public institutions to apply EPC and enhance their proactive engagement in building energy efficiency retrofitting. By considering the current status of EPC application in public institutions and drawing on relevant decision-making and behavioral theories, this paper identifies the key factors that drive the intention and behavior of public institutions, and constructs a theoretical model of the intentional and behavioral driving factors. In the empirical testing phase, research data are collected through online questionnaires. Structural equation modeling is employed to validate and analyze the extent of the driving factors and their interrelationships. The key findings are that (1) perceived usefulness, trust, and perceived risk significantly drive the behavior intention of public institutions to apply EPC; (2) perceived behavioral control and perceived ease of use significantly positively drive the behavior of public institutions, with behavior intention being the most influential factor; and (3) policy system and organizational support play a significant moderating role in the process from intention to behavior. Based on these findings, this paper proposes the critical tasks and suggests countermeasures for stakeholders in EPC projects.

Developing a typology of interventions to support doctors’ mental health and wellbeing

BackgroundThe problem of mental ill-health in doctors is complex, accentuated by the COVID-19 pandemic, and impacts on healthcare provision and broader organisational performance. There are many interventions to address the problem but currently no systematic way to categorise them, which makes it hard to describe and compare interventions. As a result, implementation tends to be unfocussed and fall short of the standards developed for implementing complex healthcare interventions. This study aims to develop: 1) a conceptual typology of workplace mental health and wellbeing interventions and 2) a mapping tool to apply the typology within research and practice.MethodsTypology development was based on iterative cycles of analysis of published and in-practice interventions, incorporation of relevant theories and frameworks, and team and stakeholder group discussions.ResultsThe newly developed typology and mapping tool enable interventions to be conceptualised and/or mapped into different categories, for example whether they are designed to be largely preventative (by either improving the workplace or increasing personal resources) or to resolve problems after they have arisen. Interventions may be mapped across more than one category to reflect the nuance and complexity in many mental health and wellbeing interventions. Mapping of interventions indicated that most publications have not clarified their underlying assumptions about what causes outcomes or the theoretical basis for the intervention.ConclusionThe conceptual typology and mapping tool aims to raise the quality of future research and promote clear thinking about the nature and purpose of interventions, In doing so it aims to support future research and practice in planning interventions to improve the mental health and wellbeing of doctors.

Sliding dynamics of a Filippov ecological system with nonlinear threshold control and pest resistance

By applying the integrated pest management strategy to address pest control problems, Filippov pest-natural enemy systems have been extensively studied. However, little attention has been paid to pest changing rate and pest resistance in these studies. Therefore, this paper proposes a complex and more realistic Filippov pest-natural enemy system with curved discontinuity boundary by considering Beddington–DeAngelis functional response and pest resistance, as well as incorporating pest changing rate in the threshold control index. Based on the relevant theory of the Filippov system, we analyze a sextic equation and obtain that the proposed Filippov system can have at most six sliding segments. By using qualitative techniques, we discuss the sliding segment and pseudo-equilibrium bifurcations. Numerically, we investigate the local and global sliding bifurcations. It can be detected that one new local sliding bifurcation occurs, which could be called the pseudo-Hopf bifurcation but differs from the traditional pseudo-Hopf bifurcation as it involves two sliding segments with opposite stabilities and generates a sliding limit cycle. We also discover two interesting global sliding bifurcations with novel bifurcation processes, which may be termed triple limit cycle bifurcations as they both relate to the appearance of three nested limit cycles.

The power of binary pulsars in testing Gauss-Bonnet gravity

Binary pulsars are a powerful tool for probing strong gravity that still outperform direct gravitational wave observations in a number of ways due to the remarkable accuracy of the pulsar timing. They can constrain the presence of additional charges of the orbiting neutron stars very precisely, leading to new channels of energy and angular momentum loss, such as scalar dipole radiation. In the present paper, we explore in detail the possibility of constraining different classes of scalar-Gauss-Bonnet gravity with binary pulsars. Additionally, we updated the existing constraints related to the observed maximum mass of neutron stars. Interestingly, depending on the equation of state, the resulting limits on the theory coupling parameters can outperform the constraints coming from binary merger observations by up to a factor of two, even for so-called Einstein-dilaton-Gauss-Bonnet gravity where neutron stars are often underestimated as relevant theory probes. As an additional merit, precise Bayesian methods are compared with approximate approaches, with the latter showing a very good performance despite their simplicity.
