Cooperativism as pedagogy: Conversation with Gustavo Machado a lecturer and researcher from Facultad de Ciencias Sociales de la Universidad de la República

This conversation with Gustavo Machado discusses the role of cooperativism as a pedagogical process in Uruguay. Machado emphasizes how cooperatives serve as models for housing production and transformative social learning processes, embedding collective action and mutual aid into daily life. He distinguishes between housing, habitat, and inhabitation, advocating for a broader understanding of living that transcends physical structures and integrates social, cultural, and communal dimensions. Our conversation delves into the political significance of cooperatives in the face of neoliberalism, positioning them as alternatives to market-based housing models. Machado discusses the challenges cooperatives face, such as state regulation and the need for flexibility in adapting to changing life circumstances. He also reflects on his personal experiences growing up in a cooperative during Uruguay's dictatorship, which shaped his political and professional views. The article highlights the intersection of cooperativism with broader social movements, such as gender equality and mental health, and the importance of international dialogue in expanding cooperative housing models across Latin America.

How Does Online Shopping Shape the Sense of Community? The Mediating Role of Various Social Activities

The rapid expansion of digital commerce, particularly same-day-delivery and next-day-delivery online shopping, is transforming daily life and community dynamics in urban settings. This study explores how these shopping behaviors impact the sense of community by mediating various social activities at both individual and community levels. Using an online survey design, this study analyzes the mediating roles of different types of social interactions, including informal social gatherings and organized community events, in shaping a sense of community. The findings reveal that while both unplanned, low-threshold interactions and more structured, organized activities contribute to a sense of community, their effects vary in strength. Stronger, more deliberate social interactions, such as resident-led events, show a full mediation effect, whereas casual, spontaneous encounters provide partial mediation. Similarly, organized community events demonstrate different levels of influence, with community-organized activities fully mediating certain sense of community dimensions and resident-engaged activities providing more comprehensive impacts. These findings highlight that same-day-delivery and next-day-delivery online shopping behaviors significantly shape the sense of community by facilitating both informal and organized social interactions.

In vivo manipulation of human gut Bacteroides fitness by abiotic oligosaccharides.

Synthetic glycans (SGs) containing glycosidic linkages and structures not identified in nature offer a means for deliberately altering microbial community properties. Here pools of SG oligosaccharides were generated via polymerization of monosaccharides and screened for their ability to increase saccharolytic Bacteroides in ex vivo cultures of human fecal samples. A lead SG preparation was orally administered to gnotobiotic mice harboring a consortium of 56 cultured, phylogenetically diverse human gut bacteria and fed a Western diet. The abundances of 3 of 15 Bacteroides strains increased, most prominently B. intestinalis. Underlying mechanisms were characterized by analyzing in vivo expression of the carbohydrate utilization machinery, using retrievable microscopic paramagnetic particles with bound SG oligosaccharides and assaying SG degradation by individual purified B. intestinalis glycoside hydrolases. The results reveal that SGs can selectively co-opt carbohydrate utilization machinery in different human gut Bacteroides and demonstrate a means for identifying artificial carbohydrate structures for targeted bacterial manipulation.

Application of the MENTOR model to advance One Health by promoting bat conservation and reducing zoonotic spillover risk

For few taxonomic groups do conservation efforts have such a disproportionate impact on biodiversity and human well-being as they do with bats. Bats face significant conservation challenges that affect their long-term viability, inhibit their ecosystem functions and services, and increase zoonotic spillover risks. Protecting bat populations and their habitats ultimately reduces these conservation threats, helps prevent pandemics, and supports essential ecosystem services. MENTOR-Bat is a fellowship program focused on strengthening technical research, and leadership capacity in the Global South to promote healthy environments where bats and humans can coexist with reduced risks of pathogen transmission. Co-designed by the United States Fish and Wildlife Service (USFWS) and Bat Conservation International (BCI), MENTOR-Bat mirrors the One Health framework by featuring a transdisciplinary team of three mentors and nine fellows from Cameroon, Colombia, and Indonesia. Fellows and mentors receive academic and field-based training on bat ecology and conservation, One Health, human dimensions of conservation, behavior change, strategic communications, international policy, adaptive management, project planning, conservation leadership, and public health. Fellows will then design and implement team pilot projects to advance One Health and bat conservation in their respective countries. Program evaluation of MENTOR-Bat is based on Kirkpatrick’s Hierarchy and focuses on measuring the development of established One Health core competences. By incorporating One Health and conservation within its activities, MENTOR-Bat can become a valuable programmatic template for transdisciplinary programming advancing evidence-based strategies for improving the well-being of bats, humans, and the environment.

Assessment of the Local Strategies Used in Abating Flash Floods for Improvement of Community Livelihoods in Nyamwamba and Bulembia Divisions, Kasese District, Uganda

Floods are intricate events that cause a range of human exposures, including loss of lives, property, and damage to infrastructure of the communities. Flash floods though often blamed on inappropriate development planning and climate variability, floods can be predicted to a reasonable extent, whose scale and nature are often less certain. The study aims at assessing the local strategies used in abating flash floods for improvement of community livelihoods. Specifically, the study explored the challenges the local communities faced during the implementation of the strategies, and also determined the relationship that emanated as a result of implementing the local strategies and community livelihoods. The study adopted a descriptive cross-sectional survey design, collecting both quantitative and qualitative data from 218 respondents and 08 Key Informants that held key responsibilities at the Municipal Council and the community. Information from the respondents and Key Informants were collected using questionnaires which was in form of interviews and face to face interviews respectively. The study shows that some local strategies have been implemented towards controlling flash floods such as, restoration of river banks (69.3%) planting bamboo trees along river banks (66%), use of gabions (65.6%), putting check dams (65.6%) and construction of manmade channels (95.9%) along the hillsides. Putting flood barriers (73%) that floods affect the community livelihoods in various aspects of daily life and the local economy in terms damage of crops (74.8%) risk of diseases (83 %) loss of livestock (60 %), displacement (93%); The challenges faced in implementation of the of local strategies in the study area include financial constraints (81.2%), technical and logistical issues (63%), poor infrastructural design (83.9%), and environmental challenges (66%). A Chi square test showed that the implemented local strategies were significantly related to the community livelihood at P=0.001. Implemented local flood strategies resulted to a positive relationship to the agricultural productivity and protected community property at P<0.05. Overall, effective flood management strategies are able to reduce risks and contribute to a better community health with fewer disruptions to community’s daily life at P<0.05. Local communities should adopt and implement the use of the mentioned local strategies like re-channeling of water pathways along the hill sides and use of gabions for flash floods mitigation since they cost effective. There should be a country-wide implementation of community-initiated mitigation measures for abating flash floods and related climate change disruptions aimed at building and promoting community resilience and livelihoods of people living in flood prone areas.

Formation and Development of Stage Ballroom Dance in Ukraine from the Mid-90s of the Twentieth Century to the Early 20s of the Twenty-First Century

The purpose of the article is to analyse the formation, tendencies and peculiarities of the development of stage ballroom dance in Ukraine from the mid-90s of the twentieth century to the early 20s of the twenty-first century. The research methodology is based on the principles of objectivity, historicism, and systematicity. To achieve the goal, the following methods were used: systematisation – to understand the combination of events in stage ballroom choreography; synthesis – to analyse the specifics of the processes of development of stage ballroom choreography in Ukraine; included observation – to review individual choreographic works, stage performances and their preliminary comprehension. Scientific novelty. For the first time, an art historical analysis of the formation and development of stage ballroom choreography in Ukraine was conducted, the specifics of the existence of ballroom choreography in the stage space were highlighted through the prism of the activities of theatres, show ballets and ballroom dance groups that have been operating since the 90s of the twentieth century. Conclusions. It is important to note that one of the most powerful areas of national choreographic art is stage ballroom choreography. Ukraine is a leader among other countries in the world in popularising ballroom dancing through theatrical and stage practice. In other countries of the world, the competition and sports direction are developing more actively, and foreign show ballets are synthesised forms of classical and modern dance with some elements of ballroom dance. Instead, Ukrainian dancers, including students and graduates of the Department of Choreographic Arts of the Kyiv National University of Culture and Arts (specialising in ballroom choreography), create a large number of choreographic productions, concerts, show programmes, musicals, ballets based on the vocabulary of ballroom choreography, which, unfortunately, remain the property of the local dance community. In our opinion, it is the lack of promotion of this art form, as well as the absence of systematic state support for this industry, that makes it impossible to convey to a wide range of viewers the high potential of ballroom choreography as a spectacular stage and dramatic art form.

Metabolic interactions shape emergent biofilm structures in a conceptual model of gut mucosal bacterial communities

The gut microbiome plays a major role in human health; however, little is known about the structural arrangement of microbes and factors governing their distribution. In this work, we present an in silico agent-based model (ABM) to conceptually simulate the dynamics of gut mucosal bacterial communities. We explored how various types of metabolic interactions, including competition, neutralism, commensalism, and mutualism, affect community structure, through nutrient consumption and metabolite exchange. Results showed that, across scenarios with different initial species abundances, cross-feeding promotes species coexistence. Morphologically, competition and neutralism resulted in segregation, while mutualism and commensalism fostered high intermixing. In addition, cooperative relations resulted in community properties with little sensitivity to the selective uptake of metabolites produced by the host. Moreover, metabolic interactions strongly influenced colonization success following the invasion of newcomer species. These results provide important insights into the utility of ABM in deciphering complex microbiome patterns.

Evolution in microbial microcosms is highly parallel, regardless of the presence of interacting species

Evolution often follows similar trajectories in replicate populations, suggesting that it may be predictable. However, populations are naturally embedded in multispecies communities, and the extent to which evolution is contingent on the specific species interacting with the focal population is still largely unexplored. Here, we study adaptations in strains of 11 different species, experimentally evolved both in isolation and in various pairwise co-cultures. Although partner-specific effects are detectable, evolution was mostly shared between strains evolved with different partners; similar changes occurred in strains' growth abilities, in community properties, and in about half of the repeatedly mutated genes. This pattern persisted even in species pre-adapted to the abiotic conditions. These findings indicate that evolution may not always depend strongly on the biotic environment, making predictions regarding coevolutionary dynamics less challenging than previously thought. A record of this paper's transparent peer review process is included in the supplemental information.

Energy management based on coalitionnal game subdivision applied to energy communities

The energy transition requires rethinking how we produce and consume energy. Energy communities (EC) provide a recent legal framework for sharing energy, aiming to reduce energy bills and the environmental footprint of their participants. One of the challenges is adapting economic models to this technological upheaval. In this context, cooperative games, based on game theory, are valuable tools for modeling energy management through cooperation. However, despite their promising characteristics, cooperative games are limited by their computational complexity. The required computation time to solve cooperative games increases exponentially with the number of participants, restricting their application in energy management. This paper aims to propose a solution to apply cooperative game theory tools to larger communities using a multidisciplinary approach. For this purpose, a game subdivision approach based on the specific properties of energy communities is proposed. This methodology will be shown to be efficient in terms of computation time. While the game theory concepts are depreciated by limiting computing time, the sub-games method can become an interesting tool in energy management. Advantages and drawbacks in terms of energy management and game theory are discussed in this paper.

The spatiotemporal stability of plant diversity is disconnected from biomass stability in response to human activities in a South American temperate grassland

Human activities alter biomass, nutrient availability, and species dominance in grasslands, impacting their richness, composition, and biomass production. Stability (invariability in time or space) can inform the predictability of plant communities in response to human activities. However, this measure has been simplistically analyzed for temporal (interannual) changes in live biomass, disregarding their spatial stability and the temporal stability of other plant community attributes. Moreover, the simultaneous analysis of temporal and spatial stabilities of plant communities has been scarcely assessed. Here, we test how biomass removal and nutrient addition simultaneously modify the temporal and spatial stabilities of plant richness (α diversity), composition dissimilarity (β diversity), aboveground live biomass, and the role of plant species dominance in the stability responses. We conducted a factorial experiment of biomass removal (grazing, mowing, or intact -no removal-) and nutrient addition (unfertilized or fertilized with nitrogen, phosphorus, and potassium) in a temperate grassland of Argentina, South America. We replicated the experiment in 6 blocks over 10 years to estimate the temporal and spatial stabilities of the plant community. The spatiotemporal stability of plant richness and composition dissimilarity decreased in the intact grassland, while the temporal stability of live biomass increased, compared to the grazed and mowed grasslands. Nutrient addition reduced the spatiotemporal stability of live biomass and the spatial stability of plant richness. The stability of species richness as well as that of composition dissimilarity was negatively associated with plant dominance, while the live biomass stability was not. Our results suggest that simplifying the effect of biomass removal and nutrient addition on grassland stability is not feasible, as plant diversity stability responses are not surrogates for biomass stability. The contrasting spatiotemporal stability responses of plant diversity and biomass represent a step forward in predicting human activities' impact over time and across space in temperate grasslands.

The “Opportunity Cost”: Care Work Compensation from a Gender Perspective in China

Asserting the value of care work within a family is not only a significant issue that affects the quality of marital life, but it also lays the groundwork for supporting the sustainable development of society and, ultimately, the country. Constantly, the theory of surplus value is employed to help understand the value of care work. However, it still lacks a macro-construction from a gender perspective. This article analyzes 15 judicial cases after introducing the Civil Code and compares the condition of application, the amount, and the factor considered in recognition of care work compensation under Chinese law. It concludes that in practice, the amount of compensation for care work remains relatively modest, with the division of the community property division heavily influencing it. At the macro level, the recognition of the economic value of the care work compensation must be emphasized from a gender construction. In contrast, at the micro level, a balance must be struck between the possibility of the other spouse benefiting from “the opportunity cost.”

Changes in the soil microbial community 5 years after the application of sewage sludge biochar to soils cultivated with corn

AbstractBackgroundSewage sludge biochar has been widely used in agriculture for various purposes; however, knowledge about its residual effect on the soil microbial community is limited.AimsThis study aimed to evaluate changes in the microbial community 5 years after the application of sewage sludge biochar.MethodsBiochar was produced from sewage sludge obtained at a wastewater treatment pyrolyzed at 300°C (Biochar300) and 500°C (Biochar500). Both biochar treatments were applied in corn fields for two growing seasons (2014/2015; 2015/2016). Biochar was not applied from the third (2016/2017) to the seventh (2020/2021) growing season to assess the residual effect. Soil samples were collected after harvesting in 2020/2021 growing season, therefore in the fifth year subject to the residual effects of biochar. The microbial community was evaluated by accessing bacterial and fungal groups using DNA techniques. Amplicon sequencing analysis was performed with the samples by Illumina MiSeq 250 bp.ResultsAt genus level, the Lachnospira, Faecalibacterium, Bacteroides, Epulopiscium, and Parabacteroides were affected by Biochar500. Furthermore, at upper levels of taxonomy, this biochar treatment increased the relative abundance of bacterial classes Clostridiaceae and Bacteroidia and the fungal families Chaetomiaceae and Aspergillaceae. Concerning the relationship between microbial community and soil chemical properties, soil phosphorus (P) and calcium (Ca) were significantly affected by biochar treatments within the bacterial community; the fungal ones affected significantly soil P and potential acidity (H + Al).ConclusionsEven under the residual effect of 5 years, the application of biochar altered the microbial community on corn plantation, especially concerning on the richness and the abundance of some groups. Biochar500 was the most responsive among the treatments.

Impact of Organic Fertilization Strategies on Soil Bacterial Community and Honey Pomelo (Citrus maxima) Properties

Soil health is a critical factor in sustainable agriculture, particularly in fruit production, where fertilization strategies play a vital role in maintaining the soil quality and enhancing fruit production and quality. This study investigates the effects of different fertilization strategies on soil bacterial communities and honey pomelo (Citrus maxima) properties in Ji’an City, Jiangxi Province, China. Three fertilization treatments were compared: conventional fertilization (CF: botanical organic plus chemical compound fertilizers), organic material fermented fertilization (OF: organic material including duck manure fermented fertilizer plus chemical compound fertilizer), and a special honey pomelo fertilizer (SF: organic material fermented fertilizer only during the whole honey pomelo growing season). Soil samples were collected at two depths (0–20 cm and 20–40 cm) from nine plots (three treatments × three replicates) and analyzed for their soil properties, bacterial community diversity and composition, and fruit characteristics. The results indicate that the OF and SF significantly improved the soil pH, soil organic matter (SOM), and nutrient availability compared to the CF. Additionally, the OF and SF treatments led to a 13.6% and 16.6% increase in fruit weight, respectively, and higher bacterial diversity, although no significant differences were observed in fruit quality parameters such as vitamin C, soluble sugar, and titratable acid. Acidobacteriota, Proteobacteria, Actinobacteria, and Chloroflexi were the dominant bacterial phyla. The soil bacterial composition structures were significantly different among the different fertilization strategies, and were well explained by soil properties such as the pH, SOM, total phosphorus, and available nutrients. Our study suggests that applying fermented organic fertilizers which use duck manure as part of the raw materials, either alone or in combination with chemical compound fertilizers, increases honey pomelo fruit production and improves soil health, contributing to the sustainable development of orchards.

Effectiveness of Training in Evidence-Based Practice on the Development of Communicative Skills in Nursing Students: A Quasi-Experimental Design.

Communication skills (CSs) and evidence-based practice (EBP) are key foundations for offering personalized and quality nursing care. CS that results in open communication is fundamental for applying EBP. The objective of the study was to assess the relationship between the acquisition of EBP competencies and learning CS after taking an EBP course in the nursing degree. Pre-test-post-test quasi-experimental study without a control group. The study population comprised fourth-year undergraduate nursing students. Before and after an EBP course, students completed a questionnaire on CS competence (HP-CSS) and EBP competence (EBP-COQ). The EBP course lasts for 15 weeks, with 150 h of work for the student. Out of these 150 h, 60 are conducted in person, while the remaining 90 h are for independent or group work, utilizing the flipped classroom methodology. Bivariate, correlational, pairwise Student's t-test, and linear regression multivariate analyses were performed. The sample was composed of 153 students. After completing the EBP course, there was a statistically significant improvement in informative communication (p = 0.046) and assertiveness (p = 0.018). However, there were no observed changes in empathy, respect, and the total score of the CS competence. The results from the multivariate analysis showed that the dimensions of attitude towards EBP and EBP knowledge had a positive relation to three of the four dimensions of the CS and overall competence. Regarding the students' variables and characteristics, admission through special programs for athletes and older students (p < 0.001) and being female (p = 0.004) were positively statistically associated with empathy. EBP training positively affects the development of CS in nursing students, as shown by significant improvements in the total scores of the CS and the dimensions of informative communication and assertiveness after the intervention. This study demonstrates the initial applicability and usefulness of an EBP training program for the development of CS in nursing students.

Deciphering the roles of bacterial and fungal communities in the formation and quality of agarwood

Aquilaria sinensis is a significant resin-producing plant worldwide that is crucial for agarwood production. Agarwood has different qualities depending on the method with which it is formed, and the microbial community structures that are present during these methods are also diverse. Furthermore, the microbial communities of plants play crucial roles in determining their health and productivity. While previous studies have investigated the impact of microorganisms on agarwood formation, they lack comprehensiveness, particularly regarding the properties of the microbial community throughout the entire process from seedling to adult to incense formation. We collected roots, stems, leaves, flowers, fruits and other tissues from seedlings, healthy plants and agarwood-producing plants to address this gap and assess the dominant bacterial species in the microbial community structures of A. sinensis at different growth stages and their impacts on growth and agarwood formation. The bacteria and fungi in these tissues were classified and counted from different perspectives. The samples were sequenced using the Illumina sequencing platform, and sequence analyses and species annotations were performed using a range of bioinformatics tools to assess the plant community compositions. An additional comparison of the samples was conducted using diversity analyses to assess their differences. This research revealed that Listeria, Kurtzmanomyces, Ascotaiwania, Acinetobacter, Sphingobium, Fonsecaea, Acrocalymma, Allorhizobium, Bacillus, Pseudomonas, Peethambara, and Debaryomyces are potentially associated with the formation of agarwood. Overall, the data provided in this article help us understand the important roles played by bacteria and fungi in the growth and agarwood formation process of A. sinensis, will support the theoretical basis for the large-scale cultivation of A. sinensis, and provide a basis for further research on microbial community applications in agarwood production and beyond.

The Influence of Interpersonal Communication on Relational Commitment in Young Married Couples in Indonesia

This study explores the impact of interpersonal communication on relational commitment among young married couples in Indonesia, employing Structural Equation Modeling (SEM) to analyze the relationships between key variables. Specifically, the research investigates how openness, empathy, support, and positive attitudes influence several critical relational outcomes, namely acquiescence, cooperation, functional conflict, and decision-making uncertainty. The study's findings reveal significant connections between the communication variables and various aspects of relational commitment. Openness and empathy emerged as particularly influential, suggesting that these dimensions of communication play crucial roles in fostering relational stability and satisfaction. Openness, characterized by transparent and honest interactions, was found to enhance acquiescence, cooperation, and reduce decision-making uncertainty and functional conflict. Similarly, empathy, involving the ability to understand and share the feelings of one’s partner, significantly impacted acquiescence and cooperation, though its effect on other relational outcomes was less pronounced. In contrast, support and positive attitudes showed varying degrees of influence across different relational aspects, highlighting their specific but nuanced roles in shaping marital dynamics. These results underscore the importance of tailored communication strategies in strengthening marital relationships. The study provides valuable insights for both researchers and practitioners focused on improving marital satisfaction among young couples. By emphasizing the role of effective communication, the research contributes to the development of interventions aimed at enhancing relational commitment and overall marital stability.

Bale Mediation as an Alternative Institution For Resolution of Communal Intellectual Property Rights Disputes Among Indigenous Communities in West Nusa Tenggara

The settlement of communal intellectual property rights disputes is not only through litigation, but is also possible through mediation. The purpose of this study is to determine the position of the mediation hall as an alternative institution in resolving communal intellectual property disputes and in the judicial system in Indonesia and how the legal force of the Bale Mediation decision is in resolving Communal Intellectual Property disputes. This research method uses normative legal research, namely legal research conducted by examining library materials or secondary data. Based on the results of the study, Bale Mediation is an institution that carries out the functions of mediation, coaching and coordination in the implementation of mediation in the community in accordance with local wisdom in the context of legal reform in the field of resolving Communal Intellectual Property Rights disputes. Bale Mediation is not part of the state judiciary but rather an institution that resolves disputes outside the courts. Legal settlement of Communal Property disputes through Bale Mediation is a non-structural institution and is responsible to the Governor. The decision or result of the dispute resolution at the Mediation Center in the form of an agreement that does not yet have permanent legal force but is only an ordinary contract for the parties, only obtains the status of a peace deed after the parties, with or without the assistance of a mediator, file a peace lawsuit through the Commercial Court/District Court.

β-Ga2O3 Nanoribbon with Ultra-High Solar-Blind Ultraviolet Polarization Ratio.

Solar-blind ultraviolet (UV) detection plays a critical role in imaging and communication due to its low-noise background, high signal-to-noise ratio, and strong anti-interference capabilities. Detecting the polarization state of UV light can enhance image information and expand the communication dimension. Although polarization detection is explored in visible and infrared light, and applied in fields such as astrophysics and submarine seismic wave detection, solar-blind UV polarization detection remains largely unreported. This is primarily due to the challenge of creating UV polarizers with high transmittance, high extinction ratio, and strong resistance to UV radiation. In this study, it is discovered that the space symmetry breaking of the β-Ga2O3's b-c plane results in a significant optical absorption dichroic ratio. Leveraging β-Ga2O3's high solar-blind UV response, a lensless solar-blind UV polarization-sensitive photodetector, circumventing the challenges associated with solar-blind UV polarizers is designed. This photodetector exhibits an exceptionally high intrinsic polarization ratio under 254nm linearly polarized light, approximately two orders of magnitude higher than other reported nanomaterial-based polarization-sensitive photodetectors. Additionally, it demonstrates significant advantages in solar-blind UV imaging and light communication. This work introduces a novel strategy for solar-blind ultraviolet polarization detection and offers a promising approach for solar-blind light communication.
