Item type:Publication, Factors affecting knowledge management and its effect on organizational performance: mediating the role of human capital(Hindawi Limited, 2021-01-01)This study aims to investigate and identify the factors affecting the empowerment and implementation of knowledge management in organizations as well as the impact of knowledge management on organizational performance. This study also examines the mediating role of human capital in the relationship between knowledge management and performance of Kabul Steel Plant, which is the largest steel plant in Afghanistan. The research model was developed through the literature review. The initial data were collected through a questionnaire containing 48 questions. Participants were 108 managers and administrative staff of the company. The collected data were analyzed by using the SPSS and SmartPLS software. The hypotheses regarding the impact of strategy and technology on knowledge management were rejected by using correlation analysis and t-test statistic. Finally, the findings showed the positive effects of variables of structure, culture, leadership, and trust on knowledge management in an organization. Also, knowledge management influences the organizational performance, both directly and through the mediating variable of human capital. This research encourages the managers and employees of organizations to use the available organizational resources to implement knowledge management in organizations and improve knowledge management practices and human resources that are the most valuable resources of any organization in order to remain competitive in the markets. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Microplastics in fisheries and aquaculture: implications to food sustainability and safety(Elsevier, 2021-06-01)Plastic waste has arisen as a worldwide environmental concern, becoming ubiquitous in all marine compartments. Microplastics (MPs) are an important fraction of this accumulation, due to direct emissions from the technosphere or fragmentation of macroplastic waste. Consequently, the aim of this letter is to analyze the effects of microplastics on fishing and aquaculture, identifying the links with food safety and sustainability. Current studies have observed multiple potentially damaging effects of microplastics on marine biota, mainly at lower trophic levels. It is plausible to assume that fishing stocks and aquaculture systems will suffer setbacks due to these damages. However, additional research is needed to understand the potential effects on human health, especially considering that smaller microplastics and nanoplastics, for which data is very scarce, are the particles most likely to be absorbed by human tissues. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Investment modeling for scalable agricultural learning(Public Library of Science, 2026-03-01)With the rise of information and communication technologies, localized farmer training can be transformed into scalable strategies applicable across diverse communities, cultures, and languages. However, the economic value of these approaches and the factors shaping their returns remain underexplored. This study presents a general framework for evaluating the economic impact of scalable agricultural learning initiatives, using multilingual instructional animations and YouTube dissemination as a case study. Systems modeling was used to simulate potential returns, assess key drivers of impact, and estimate the number of farmers required for economic viability. Sensitivity analysis shows that returns are most influenced by the cost to inform an individual, adoption rates, and income gains, and to a lesser degree, technique-sharing rates and adoption costs. When existing educational content is adapted and its lifespan extended, learning initiatives can be economically viable with few targeted farmers, making the linguistic adaption into minority or rarer languages an economically viable option. The wide variation in returns across scenarios highlights the importance of tailoring models to specific contexts to obtain more precise estimates of economic impact. These findings underscore the value of adaptable and durable learning materials and suggest that future research-for-development (R4D) investments could benefit from systems modeling to identify and prioritize high-impact agricultural solutions.1 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Geoglyphs and formative-period activity in the middle Chillón Valley, Peru: Ceramic association and null-model tests of route proximity(Public Library of Science, 2026-06-01)Geoglyphs are widespread in arid landscapes, but their chronology and relationship to movement corridors are often difficult to evaluate where direct dating is unavailable. This study examines four geoglyph groups documented through systematic pedestrian survey and RPAS-based recording in two quebradas of the middle Chillón Valley, central coast of Peru: Huarabí (n = 2) and Pichausa (n = 2). Chronological inference is necessarily limited. Diagnostic Formative-period ceramics were recorded only in Huarabí, where they indicate nearby activity rather than directly dating geoglyph construction. Pichausa remains chronologically unresolved. To evaluate whether the documented geoglyphs occur closer to mapped route proxies than expected under explicit counterfactual assumptions, we measured nearest-route distances from within-geoglyph sampling points (k = 20 per geoglyph; n = 80 total) and from six unweighted Formative ceramic findspots in Huarabí. Observed distance distributions were compared with Monte Carlo simulations in which geoglyph shapes were randomly repositioned within defined survey windows while route geometries remained fixed. Across 999 simulations, Huarabí deviates from the tested null model under the survey-polygon window, or buffer = 0 m (p = 0.021), whereas Pichausa does not (p = 0.380). Results vary substantially under broader availability windows, indicating that inference is strongly conditioned by how potential placement space is defined.. These findings provide exploratory, model-dependent evidence that some Huarabí geoglyph contexts and associated ceramic findspots occur nearer to mapped route proxies than expected under the specified null model. They do not establish intentional route association, geoglyph construction age, or valley-wide spatial organization. The principal contribution is methodological: the study demonstrates how small geoglyph datasets can be evaluated through transparent null-model procedures while making explicit the limits imposed by sample size, surface chronology, spatial uncertainty, and the absence of terrain-based feasibility modeling.
