ABSTRACT Peer‐reviewed publications remain the most accepted form of knowledge production and distribution in academia today. But such formal publications are often deeply exclusionary, especially for undergraduate and early graduate students as well as scholars tackling highly stigmatized subjects. This essay highlights the value of zines—do‐it‐yourself booklets that mix art and text in an eclectic assemblage—as an alternative. Drawing from my personal DIY experiments as well as those of other anthropologists, I make the case that zines offer several advantages when compared to peer‐reviewed publications. First, they are pedagogical tools that invite playful engagement with disciplinary knowledge and theory while also familiarizing early scholars with basic publication processes. Second, they serve to expand and diversify anthropological scholarship by encouraging experimentation with both text and image while also challenging disciplinary norms and conventions. Third, zines are a form of knowledge sharing that generates intimacy through their materiality and tactility—forging connections between the reader and text but also the reader and author. Finally, because zines are self‐published, creators exert considerable control over the production and distribution of the work that is shared, offering specific benefits from the standpoint of the political economy of knowledge production.

Climate communication has emerged as a distinct form of communication, encompassing public communication activities designed to ensure that information and scientific data about climate change are disseminated in an accessible manner to society and the public. The objective of this research is to elucidate the manner in which climate change communication is constructed in the media at the semiotic level, in the context of public communication, using the local example of Türkiye. In this study, the posters published by the Turkish Ministry of Environment, Urbanization and Climate Change on 15 May 2024 World Climate Day to draw attention to climate change were subjected to a semiotic analysis using Roland Barthes’ concept cluster as an analytical framework. The analysis yielded three dominant themes: the Anthropocene myth, the environmental catastrophism myth and the sustainability myth. The analysis revealed that the Ministry attributed responsibility to individuals, omitted the primary sources of the problem, and employed symbols to evoke fear and emotional attachment. The expressions and symbols used in climate change posters emphasize individual change and movement, and the construction of fear appeal is focused on individuals. This study makes an original contribution to the literature in terms of understanding climate change indicators in the context of public communication, showing that individual change is focused on in creating awareness about the climate crisis. However, the examined posters did not address the destructive effects of the economic systems, government policies, and production processes that underlie the climate crisis.

Amla, or Indian gooseberry, (Phyllanthus emblica Linn.) fruit primarily contains antioxidant and immunomodulatory properties and leaves contain phenolic compound and alkaloids such as phyllantine and phyllantidine. A feeding trial was conducted to discern the influence of dietary inclusion of amla (Phyllanthus emblica) leaf powder on growth performance, nutrient utilization and economical production of Japanese quail. A total number of 180- day-old Japanese quail chicks were randomly distributed into five treatments of 36 Japanese quails per treatment with three replicates in each in a completely randomized design. Five treatments included control (T1) in which standard diet without any supplementation was fed, while in T2, 0.5% Amla fruit powder (AFP) with standard diet was fed and in T3, T4 and T5 with 0.5%, 1.0% and 2.0% Amla leaf powder (ALP) incorporation respectively with standard diet. Results showed that 1.0% dietary inclusion (T4 group) emerged as the most economical treatment, as it recorded the lowest cost per kilogram body weight gain (116.76 ± 0.42) along with significantly higher net profit (42.28 ± 0.06). It can be concluded that 1.0% dietary inclusion of amla leaf powder (ALP) being the most effective in improving growth rates, feed efficiency, nutrient digestibility and desired economical production of the Japanese quail.

David Throsby made significant contributions to cultural economics, making the field visible in academic economics. His work extended beyond standard economic tools, recognizing that artistic practices require new economic approaches. Building on Throsby’s value approach, this paper explores how cultural goods differ from standard economic products, emphasizing their shared and common nature. It examines the cultural and social dimensions of these goods, analysing their role within the commons. By integrating diverse literature sources, the study proposes a taxonomy of commoning practices, addressing research gaps and future inquiries. It highlights the multiplicity of values—such as aesthetic, social, and historical—demonstrating how cultural goods function beyond financial worth within communities and shared practices.

This text is based on the problem of the implications of the high school counter-reform in relation to Decree No. 5.154/2004 (Brasil, 2004) and the possibility of integrating vocational education and high school in the sense of polytechnics. The main objective is to compare the proposal for integrated secondary education with the proposal for the new secondary education and to analyze the implications of the reform. The methodology is based on bibliographical and documentary research. The results indicate that Decree No. 5.154/2004 (Brasil, 2004) and Law No. 13.415/2017 (Brasil, 2017) move in opposite directions, while the former is based on comprehensive and polytechnic training and training for the world of work, the latter proposes simplified and fragmented training based on the development of skills aimed at economic production. In addition, the conclusions reflect a regression in the education of the children of the working class.

Coenurosis is a neurological ailment caused by the larval stages (Coenurus cerebralis) of Taenia multiceps, a parasite that significantly affects sheep production worldwide. This study aimed to determine the prevalence of C. cerebralis infection and to characterize it clinically, pathologically, and molecularly in infected sheep from 15 districts of Salah Aldeen Province, Iraq. A cross- sectional study extending from March 2024 to February 2025 was conducted, involving the clinical examination of 450 sheep. Sheep exhibiting clinical signs of coenurus infection were further subjected to postmortem for confirmation of the suspected disease. Molecular identification of coenurus was done by PCR amplification of the mitochondrial cytochrome c oxidase subunit 1 (cox1) gene and the internal transcribed spacer 1 (ITS1) region. A total of 39 sheep were confirmed for coenurosis, resulting in an overall prevalence of 8.67% (95% CI: 6.28-11.67%). There was a wide spatial variation among the districts, with prevalence ranging from 3.33% in Fares district to 16.67% in Tikrit district. The most common clinical signs associated with infected sheep included circling behaviour (76.9%), head tilt (64.1%), blindness (43.6%), and ataxia (38.5%). The highest number of cases was recorded during winter months (December-February) with 14 cases (35.9%) followed by spring (March-May) with 11 cases (28.2%). Summer months (June-August) showed the lowest occurrence (6; 15.4%) followed by Autumn (September-November) with 8 cases (20.5%). Postmortem examination revealed that coenurus cysts were predominantly located in the cerebral cortex (48.7%) and cerebellum (35.9%) of infected sheep. In most confirmed cases, PCR successfully amplified fragments of the cox1 and ITS1 genes, confirming the morphological diagnosis. This study demonstrates that C. cerebralis infection represents a significant health concern for the sheep of Salah Aldeen province, which could potentially hinder the economic sheep production in the study area. The study highlights the importance of integrated clinical, pathological, and molecular approaches for accurate diagnosis of the disease and the data generated provides a valuable baseline epidemiological information for the development of effective and strategic prevention and control programs for coenurosis in the region.

Economic gas recovery from shale reservoirs is inherently difficult because of the extremely low permeability of these formations. To overcome this challenge, horizontal wells are drilled and subjected to multi-stage hydraulic fracturing treatments, which generate high-conductivity flow pathways. The adoption of these technologies has significantly boosted the economic recovery of gas from shale formations, particularly the Marcellus Shale, which stands as the most productive shale gas play in the United States. The effectiveness of a fracturing treatment in enabling economic gas production from shale reservoirs is governed by the characteristics of the fractures it creates. The propagation of initial fracture, during multi-stage hydraulic fracturing, modifies the initial stress conditions in the surrounding area, commonly referred to as a “stress shadow.” The stress shadow restricts the initiation and subsequent propagation of later fracture stages, leading to the development of less favorable fracture properties. As a result, the uneven contribution of individual fracture stages to gas flow ultimately diminishes overall gas recovery from the horizontal well. For efficient gas drainage from the shale, the fracture stages are often closely spaced. When fracture stages are placed in close proximity, the stress shadow effect can be intensified. Thus, accounting for the stress shadow is essential in the design of hydraulic fracture treatments. This study investigates how fracture spacing, injected fluid volume, and fluid type influence the magnitude of the stress shadow effect, its impact on fracture properties, and the resulting gas recovery from the Marcellus Shale. The goal is to facilitate the optimization of the hydraulic fracture design to mitigate the stress shadow impact and enhance gas production. Data from several Marcellus Shale horizontal wells, along with published findings, were compiled and analyzed to determine the petrophysical and geomechanical characteristics of the formation. These results were then used to construct a reservoir model representative of a Marcellus Shale horizontal well. Fracture properties, altered by the stress shadow, were assessed through hydraulic fracturing simulations and incorporated into the model. Ultimately, the reservoir model was employed to predict the production performance. The results of the investigation confirmed that close stage spacing intensifies the impact of the stress shadow. The stress shadow was found to impair fracture conductivity which negatively impacted gas recovery. The negative impact of the stress shadow on gas recovery was observed to gradually diminish as the production rate declined over time. The volume and type of the fluid injected during fracturing treatment can amplify the stress shadow’s impact.

Plant-based biomaterials, prized for their inherent biocompatibility and biodegradability, serve as excellent candidates for biomedical applications. This is largely due to the unique pharmacological properties of their bioactive metabolites. However, the sustainable and economical production of these metabolites, particularly from rare and endangered species, remains challenging. In this study, we developed a multicellular spheroid-based cultivation strategy using medicinal plant cells to efficiently produce bioactive metabolites, exemplified by the endangered species Saussurea involucrata (SI). Optimized culture conditions stimulate sustainable production of SI-derived secondary metabolites (SIM) enriched with antioxidant and anti-inflammatory constituents. Single-cell transcriptomics identify nine functionally specialized cell clusters responsible for the biosynthesis of pharmacologically active constituents. Ultra-high performance liquid chromatography-MS/MScatalogs 679 metabolites, with a chemical profile closely resembling that of wild SI. Network pharmacology links SIM to 318 therapeutic targets relevant to alcohol-associated liver disease (ALD). In vitro, SIM decreases reactive oxygen species, suppresses hepatocyte apoptosis, and attenuates macrophage-mediated inflammation. In an ALD mouse model, SIM administration alleviates hepatic lipid accumulation, restores liver function, and favorably remodels the gut microbiota. Together, these results establish a sustainable biomanufacturing paradigm for bioactive compounds from rare medicinal plants and highlight SIM as a promising candidate for ALD therapy.

Introduction . The article is devoted to the consideration of theoretical and methodological issues of the transition from traditional organizational structures of management of industrial enterprises to new forms of organizational structures demanded by the modern stage of technological development. The industrial development of the global economy and technological breakthroughs in production invariably become an impulse to change the management system of enterprises. Technologies are changing quite a lot in society, making more and more demands on the competencies of employees. Such transformations initiate shifts in the corporate culture of the enterprise, forcing owners and management to move away from the traditional management paradigm. The article attempts to generalize and systematize the existing organizational structures of industrial enterprises and identify trends in their transformation in the context of the development of Industry 4.0 in the context of digitalization in the knowledge management framework. Studies of organizational structures within the framework of the industrial development of the economy have been conducted and patterns of transformation of management mechanisms and paradigms have been identified. A fractal model of the organizational structure is proposed in the proposed evolutionary change in the management paradigm, which is gradually changing its targets in the context of social transformation. Materials and methods . The research is based on materials from different years on the organizational and cultural transformation of business due to technological changes. General scientific methods of analysis, synthesis, and generalization are used. The experience of global business shows that these two factors are interconnected. Recent studies [30] of European enterprises show a different degree of receptivity of corporate culture and organizational management structure to innovative transformation related to Industry 4.0 technologies and digitalization of business processes. Research results . The industrial development of the global economy and technological breakthroughs in production invariably become an impulse to change the management system of enterprises. This study shows the most diverse forms of organizational management structures, which nevertheless have a similar methodology within the framework of a single management paradigm. Technologies are changing quite a lot in society, making more and more demands on the competencies of employees involved in the entire life cycle of industrial products, which is inevitably reflected in the management paradigm. Discussion and conclusion . On the threshold of the fourth industrial revolution, in addition to tectonic technological shifts, we expect no less grandiose organizational and managerial transformations in order to fully utilize the potential and advantages inherent in the new Industry 4.0 solutions.

Abstract Introduction: Agroecological farming has emerged as a promising approach for managing crop pests, including the ‘true’ fruit fly (Diptera: Tephritidae), in cucurbit production. Cucurbits are important for both nutrition and income generation, making effective pest management critical to ensure sustainable yields and improved farmer livelihoods. Despite the growing promotion of agroecological practices as alternatives to synthetic pesticides, evidence on their economic benefits remains limited. Methods: This study was conducted in Morogoro Region, Tanzania, through field experiments, to compare the economic impacts of agroecological and conventional management practices in cucurbit crop production. Discussion: Results showed that management practices significantly ( P < 0.05) influenced both marketable fruit weight and production costs. For squash, agroecological plots yielded significantly higher marketable fruit weights compared to conventional plots, while for watermelon and cucumber, yields were comparable across the two practices. Production costs were consistently higher under conventional management for all three cucurbit crops. Furthermore, the net profit and cost–benefit ratio were significantly higher ( P < 0.05) in agroecological systems. Conclusion: The findings indicate that agroecological pest management presents significant economic benefits compared to conventional methods. This approach offers a sustainable and cost-effective alternative for reducing reliance on synthetic pesticides in cucurbit production systems and agriculture. Significance of the study What is already known on this subject? Crop cultivation based on agroecological principles can reduce production costs and provide long-term benefits to smallholder farmers. Although the application of agroecological farming practices in cucurbit production has been studied mainly in relation to insect control, the evidence on their economic benefits remains limited. What are the new findings? Agroecological pest management presents significant economic benefits compared to conventional methods. This approach provides a sustainable and cost-effective alternative that reduces dependence on synthetic pesticides in cucurbit production and agricultural systems. What is the expected impact on horticulture? This study provides an overview of the economic benefit and production costs associated with agroecological farming practices and recommends a way forward for a wider implementation of agroecological farming in small-scale cucurbit farmers towards sustainable farming systems for human and environmental wellbeing.

Abstract The scholarship on peri-urban agriculture lacks historic analysis, making the history of Shanghai's vegetable supply system particularly useful. In the early 1950s, a substantial portion of Shanghai's vegetables came from distant rural areas. Although the municipality stimulated vegetable production in its suburbs, this reliance on rural areas remained unchanged for a time. However, in 1958, these rural sources of vegetables were abruptly cut off, compelling Shanghai to rely on suburban production. This transition led to the establishment of a suburban-centric system. Nevertheless, efforts to sustain the system encountered numerous challenges. The government tried to phase out the planned economy in vegetable production during the 1980s, although with limited effect. In the early 1990s authorities abandoned the suburban-centric system and introduced a reform strategy of “grand circulation,” once again leading to the predominance of nonlocal vegetables. The history of Shanghai's suburban vegetable supply system thus elucidates the limitations of peri-urban agriculture.

Probiotic use has become more important in aquaculture for healthy and sustainable output. In particular, Bacillus spp. have emerged as effective probiotic agents, improving gut health, enhancing the immune system, promoting growth, and providing protection against pathogens in fish. Therefore, the application of Bacillus in aquaculture offers a strategic approach to increasing productivity while reducing the reliance on antibiotics. In this study, the antibacterial activities of Bacillus isolates, whose probiotic properties will be determined, against test bacteria that are fish pathogens such as Aeromonas hydrophila, Vibrio anguillarum, Lactococcus garvieae, and Yersinia ruckeri were determined by using cross-streak method and agar well diffusion methods. Then, antibiotic resistances of 75 isolates determined to have antibacterial activity were screened against 9 different antibiotics by the agar disc diffusion method. Gastric juice (pH 2.5) tolerance of 55 isolates determined to be sensitive to antibiotics was examined, and the tolerance of 13 isolates to gastric juice was determined. Optimum growth characteristics at acidic pH, surface hydrophobicity, bile tolerance, and protease, amylase, lipase, and cellulase activities, hemolytic activities, coagulase activities, bacterial adhesion abilities, and biofilm production properties of these isolates were determined. As a result, Bacillus subtilis Ö-4-68, with the best probiotic properties, was selected from the examined isolates, and production medium optimization was carried out with laboratory scale statistical experiment design (Response Surface Methodology, RSM) for high amount of biomass production. As a result of the trials, an economical cost-effective production medium content with high biomass production was determined.
