Comprehensive evaluation of antibiotic pollution in a typical tributary of the Yellow River, China: Source-specific partitioning and fate analysis.

The partitioning and migrating of antibiotic residues pose a considerable pollution to the river environment. However, a source-specific approach for quantifying the fate of antibiotics is lacking. To further elucidate the migration behavior of antibiotics from different pollution sources in aquatic environments, we introduced a source-specific partition coefficient (S-Kp) based on Positive Matrix Factorization (PMF) model to improve the multimedia model. This study identified six sources of antibiotic pollution in the water and sediment of the Fenhe River. Farmland drainage contributed 2.6 times more antibiotics to sediment than to surface water, whereas livestock sources contributed 0.3 times less to sediment than to water. High S-Kp values were primarily obtained from livestock, aquaculture, and farmland drainage pollution sources, with an average S-Kp value exceeding 200 L/kg. Sulfaquinoxaline (SQX) in sulfonamides (SAs) from livestock sources exhibited the highest S-Kp value of 34,740.04 L/kg. The predicted environmental concentrations indicated that almost 99 % of the antibiotics from the six sources remained in the water phase, with the highest contribution (99.9 %) of azithromycin (AZM) from livestock, pharmaceutical wastewater, and domestic sewage. This study provides novel insights into the migration of antibiotics from source-specific partitions in multimedia environments of watersheds.

Interactive Multimedia Environment Intervention with Learning Anxiety and Metacognition as Achievement Predictors

Background: Interactive learning environments have emerged as transformative tools in education, enhancing engagement, academic performance, and addressing challenges like learning anxiety. This study examines the influence of multiple variables, including anxiety, internet usage for problem-solving, attitude towards a history course, metacognitive awareness, and interactive learning environments, on seventh-grade students’ academic performance. Methods: Using the Exploration of Attitudes Towards History Scale (EDIS) scale to measure attitudes and the Metacognitive Awareness of Reading Strategies Inventory-Revised Two-Factor Version (MARSI-2fR) to assess metacognitive awareness, the study evaluated historical knowledge across three stages, namely pre-intervention, post-intervention, and a one-month-later retest. A comparative analysis was conducted between the control group and the intervention group. The statistical analyses involved the calculation of correlation coefficients, the implementation of general linear models, and the performance of Wilcoxon signed-rank tests. Results: The findings indicated that prior to the intervention, factors such as learning anxiety and the extratextual component of metacognition were statistically significant predictors of achievement. However, the aforementioned factors ceased to be statistically significant when the parameter of study strategies was incorporated into the statistical model. The impact of the interactive learning environment on students’ achievement is highly statistically significant in terms of post-test scores, while the influence of all other predictors becomes insignificant. The retest confirmed the continued maintenance of the achieved results as evaluated following the intervention. Conclusions: The study confirms previous research demonstrating that interactive learning environments are an effective method of enhancing students’ academic performance and reducing the negative impact of learning anxiety.

Children Centered Care: child and parent perspectives on a multi-faceted concept for magnetic resonance imaging without anesthesia - a survey.

Anxiety-provoking healthcare procedures require specific child-friendly approaches. Magnetic resonance imaging (MRI) can cause anxiety for children and general anesthesia (GA) is often used. We developed and tested a multi-faceted child-friendly concept, Children Centered Care, for MRI of children without GA. To investigate children's and parents' individual experiences with the concept using a survey. The main aim was to evaluate comfort for children and sense of security for parents during unsedated MRI. In this prospective study of 265 children aged 4-10years enrolled in 2016 and 2017, the Children Centered Care concept is compared to a standard setup. The concept included an interactive app, trained pediatric radiographers, a children's lounge with a toy-scanner, and a child-friendly multimedia environment in the scanner room. A 25-item survey was used including a mix of open and closed questions, free text, and a visual analogue scale to evaluate self-reported child comfort. A total of 154 children were included in the Children Centered Care group and 111 in the standard group. Overall, the mean age was 8.5years (range 4.0-10.9years). With Children Centered Care, child comfort increased (88% vs. 77%), P = 0.02. The app and toy-scanner were popular among children. More parents felt "very much" prepared (80% vs. 57%), P < 0.01, and "very much" secure (92% vs. 79%), P < 0.01. With the use of a multi-faceted, child-friendly concept, MRI without GA is a feasible first choice for children aged 4-10years, with high levels of comfort for children and parents.

Challenges for being self-directed in content and language integrated learning with instructional videos

Self-directed skills are crucial for video-based learning as learners often need to manage their pace, set goals, and engage with content independently. While much research focuses on the effectiveness of design and design principles in facilitating self-directed learning (SDL) in multimedia environments, boundary conditions arise due to the highly individualized and unique nature of each learning trajectory. This paper reports the findings of a case study involving five university students who speak English as an additional language (EAL). It explores the difficulties they faced while learning mathematics with instructional videos and the approaches they used to address these challenges in the context of Content and Language Integrated Learning (CLIL). Findings from video-stimulated recall (VSR) and semi-structured interviews reveal that language issues influenced and drove many decisions in their self-directed learning paths. Notably, the challenges of grasping academic language and terminology led participants to spend considerable time and effort on navigating video designs to aid language comprehension and on seeking extra resources to better understand the lectures. However, the lack of timely feedback and expert guidance posed further challenges for these EAL learners in identifying their knowledge gaps, thereby complicating the search for resources appropriate to their language and academic levels.

포스트 시네마 환경에서의 관객 현전에 관한 연구

This study defines the diversified media environment of contemporary visual art as a post-cinema environment and analyzes how the spatial expansion of the screen and the conceptual transformation of the camera have occurred within it. By examining the altered methods of image production, mediation, and reception, the research reveals the presence of the spectator as a noncorporeal subject in the visual field of image experience. The changes in the screen and the audience have been driven by the transition to multi-screen and multimedia environments, leading to a transformation in visual perception through physical environments that interact with images in expanded spaces. Additionally, the post-cinema camera, as a non-human agency, has broadened the scope of image production and mediation through computer imaging processes and digital technologies. It not only intervenes between the unexperienced realities beyond human cognition and the audience as the experiencing subject, but also produces and mediates images for machines as machine vision, facilitating the process of converting representation into information. Furthermore, this study argues that the issue of spectator presence in the visual field can be understood through the paradox of absence and presence in the technological context of 21st-century media. It asserts that the spectator emerges as an “electronic body” that transcends the physical body in the image reception environment. The concept of the audience's electronic body introduces perspectives on the coding and informatization of the body due to technological interventions by computers and media, as well as the hybrid sensations resulting from the interaction between bodies and devices, proposing a new notion of corporeality for non-corporeal subjects in the new media environment.

The Power of Images: How Multimodal Hate Speech Shapes Prejudice and Prosocial Behavioral Intentions

While online hate speech has become a serious problem in multimedia environments, most studies in this area have examined text-based hateful content, with less attention paid to its other visual aspects. From a multimodal perspective, we conducted an online experiment ( N = 799) to investigate how multimodal hate speech (i.e., text and images presented together to convey hateful meanings) on social media affected users’ prejudicial attitudes and prosocial behavioral intentions. The results showed that participants in the text-plus-image (vs. text-only) condition felt more sympathy, which led to less implicit prejudice toward the target group and more prosocial behavioral intentions. In addition, exposure to text-plus-image hate speech had an indirect effect on prosocial behavioral intentions through sympathy and implicit prejudice. The findings contribute to scholarship on online hate speech and provide insights into the affect heuristics that individuals rely on when processing multimodal information.

Assessing self-efficacy, working memory, and proficiency in a multimedia writing environment

Abstract The present study examined self-efficacy, working memory, and English proficiency in a multimedia writing environment. The research design included a survey to assess self-efficacy and a writing assessment within a multimedia environment, while controlling for working memory capacity and levels of English proficiency. Data collection methods comprised a survey on self-efficacy beliefs in multimedia writing, a working memory task, and the standardized College English Test Band 4 in China. The participants were a total of 406 Chinese university students. The results support the reliability of the self-efficacy questionnaire, with five dimensions: linguistic knowledge, planning, monitoring, evaluation, and performance. These five factors were positively correlated with the students’ writing performance in a multimedia environment. The structural equation modeling findings suggest that working memory and English language proficiency moderate learners’ self-efficacy in EFL multimedia writing. Relevant implications based on the findings were discussed.

Modeling nitrogen behavior in Tigris River using system dynamics approach

Nitrogen behavior across multimedia environment like Tigris River is complex process resulting in a number of interactions of the biogeochemical processes. A solid understanding of the interacted processes is critical to evaluate river system performance. Inorganic nitrogen including ammonium ion (NH4+), free ammonia (NH3), total ammoniacal nitrogen (NHx), nitrite (NO2−), nitrate (NO3−), total oxidized nitrogen (NOx), and total inorganic nitrogen (TIN) in Tigris River were examined from April 2018 to March 2020. A simple system model was implemented to simulate and to help interpret the trend of inorganic N forms based on datasets collected from the river system. It is indicated that the obtained results revealed that the dynamic model was able to represent and predict NHx and NOx behavior in Tigris River. Root mean squared errors between actual and predicted concentrations for NHx and NOx were 0.053 and 0.312 g m−3, respectively. Modeling analysis confirmed the steady-state dynamics of NHx and NOx over the course of the study. Average concentration for NHx was 0.37 ± 0.05 g m−3, while mean value of NOx levels was 2.18 ± 0.33 g m−3 in the Tigris river water. The results from this study also supported by the changes of the water budget, chemical oxygen demand, pH, dissolved oxygen, electrical conductivity, and water temperature in the river system. The results suggest that the microbial mechanisms are the principal N transformation processes in the river system. Findings presented in this research could help to improve conceptual understanding of N behavior in Tigris River, and therefore could assist decision makers to select best management practices and to develop mitigation strategies to sustain water quality in Tigris River.

Learning motivation of college students in multimedia environment with machine learning models

As the main force of higher education, ensuring the learning status and quality of college students is undoubtedly an important task in the education industry. Analyzing their learning motivation can provide a good understanding of their learning status. Especially in the new educational environment supported by multimedia technology, efficient and convenient learning channels can eliminate students' concerns about educational facilities and instead strengthen the analysis of learning motivation in other aspects. As part of our comprehensive study of learning motivation, we draw on established learning theories, such as reinforcement theory, associative learning, and self-determination theory. Applying such learning theories encourages positive reinforcement, establishes constructive relationships with learning, and nurtures competence and autonomy. This article believed that using machine learning models to predict students' grades or behaviours and analyze their learning motivation is a good approach. Moreover, this article also tested the prediction accuracy by setting different improved random forest model runs, and concluded that the more runs, the higher the accuracy. Especially when the runs reached 100, the accuracy reached 99.98 %.

Investigating Knowledge Gain and User Satisfaction in UAS Safety Modules: A Pilot Study

This study investigates whether the presence of relevant images or progress indicators in an online multimedia training will improve knowledge gain and satisfaction. It was hypothesized that both knowledge gain and satisfaction increase with the inclusion of images and progress indicators. A randomized pretest-posttest 2 × 2 factorial design was used to examine the impact of relevant images and progress indicators on knowledge gain and satisfaction in an online multimedia environment. Results suggested that satisfaction increased when the training had both pictures and progress indicators. On the other hand, there did not appear to be a significant difference in knowledge gain between conditions.

The Source of Parabens in Urban River Water: The Evidence From Outdoor Multimedia Environment in Six Metropolitan Cities, China

Optimization Problems for Assessing the Relative Importance of Elements in the Analytic Hierarchy Process

Analytic hierarchy process (AHP) was proposed by American scientist Thomas Saati. It is a closed logical structure that, with the help of hierarchies, priorities and simple mathematical rules, provides analysis of complex problems in all their diversity. Analytic hierarchy process is successfully used for solving practical problems and quite often leads to optimal answers for planning, forecasting and other problems. It can also be applied to system analysis of the using multimedia factors for increasing the effectiveness of patients’ rehabilitation at various stages of disease.The article proposes two optimization problems for coefficients analysis in the matrix of pairwise comparisons of elements for analytic hierarchy process, with criterion is minimization of the matrix consistency index. The first problem is related to finding integer coefficients in the scale of T. Saati subject to insignificance of components deviations of the vector of priorities of elements rounded to two digits from the given ones. The second problem is related to correction of the specified pairwise comparisons matrix coefficients subject to upper bound on total deviation of the matrix coefficients from the specified ones and subject to deviation of the rounded components of the element priorities vector from the specified components.Calculations of the optimal coefficients in both optimization problems for the example of T. Saati related to study of lighting intensity and the law of the inverse square of the distance to the light source are given. An example of the second optimization problem application for correcting matrix of pairwise comparisons, which was built by a rehabilitation doctor to assess the importance of four elements of the multimedia environment when including them in the rehabilitation program, is considered.The material of the article is presented in three sections. Section 1 describes T. Saati’s example from the study of light intensity and the law of the inverse square of the distance to the light source. Section 2 describes the first optimization problem and provides calculations of the optimal coefficients for the pairwise comparisons matrix for the example of T. Saati. Section 3 describes the second optimization problem and gives examples of its application to bring the already existing pairwise comparisons matrix to the pairwise comparisons matrix with better consistency index both for the experiment of T. Saati and for the analysis of using of multimedia factors for improving efficiency of patients’ rehabilitation.
