Cenotaph and Elegy of Contagion: Collective Immersion of National-Level Covid-19 Fatality Data in the United States
Authors: Huang M. Jerry , Loveless Stephanie , Braasch Jonas
Published: October 2024

Effective representation of epidemiological data is essential for informing the general public about the extent of disease contagion, yet hard to achieve. On the one hand, the expressiveness of statistical visualization is often limited. On the other hand, explicit data sonification is lost in translation, failing to capture the meaning of the data at hand. The ongoing COVID-19 pandemic, which has caused excessive fatalities in the world and the United States, has presented us with a timely opportunity to address both challenges at once. In this work, we use the room-oriented immersive system (ROIS) to sonify and visualize the United States’ national-level fatality data for the first 1000 days of the pandemic. Reimagining ROIS as a cenotaph that can be experienced collectively from within, a visual timeline in upward motion is spatially distributed to represent individual fatality cases in scattered point densities, resulting in the weighty perception of downward self-motion. The visualization data is spatially subdivided and compressed into multi-channel spike chains with variant embeddings. The sonification, or elegy, uses a self-assembled dataset of heavy breathing sounds and is synthesized as virtual sound sources through a finite convolution-sum technique. The integrated result demonstrates the method’s broader ability to effectively convey the relationship between human behaviors and pathogenic evolution through collective immersion while delivering a responsible representation of infectious disease statistics.
Sounding Numbers: The Sonification Object as an Interface in "I Am the Ocean"
Authors: Crozzoli Miguel Angel , Magnusson Thor
Published: October 2024

Designing sonification for music composition involves aesthetic and narrative manipulation through strategies based on compositional intent, sparking discussions of data clarity and understanding. This paper describes an autobiographical process of crafting an aesthetic sonification from climate change data, and its further musification. In this approach, the sonification is used as a material for composition and transformed into an interactive musical instrument, within contemporary aesthetics and live performance contexts. The sonification object becomes an interface for composition and performance. The resulting piece seeks to amplify engagement through affectivization while displaying data infor- mation via symbolic abstraction and musical narrative. The paper also describes the techniques and results of blending sonification sounds with mixed notation derived from the sonification object. The composed piece was recorded and played by an electronic-acoustic contemporary ensemble to an audience which later gave feedback. The conclusion drawn from this musification project was that even though the source data was not directly perceivable in detail by the audience, the piece does convey information via the power of emotional affectation, which aligns with the original intention of the project.
Temporal Imagery for Aural Diversity: Auditory Displays as Artifacts of Sonic Art Encounters Between Unaided and Cochlear Implant Listeners
Authors: Ramakrishnan Sharath Chandra
Published: October 2024

This paper advocates for the position that aurally diverse methodologies for designing auditory displays are needed, that not only take into account varied hearing capacities, but also conceive of a participatory and trans-disciplinary approach for collectively engaging diverse forms and conversations about listening, and shared associations with auditory imagery. Further, in light of the complex history that the notion of hearing disability and the evolution of commercial sound technology has had within the normalizing agenda of medical institutions, a call for methods of engagement that necessarily depart from the ubiquitous model of clinical testing for the ideal ‘ear’ is made. The paper illustrates this position by extrapolating possibilities within the context of a subset of machine mediated listening, specifically cochlear implant based listening. It proceeds by speculating how auditory displays that rely on temporal perception may produce shared associations in auditory imagery, and a meeting ground for unaided listening and cochlear implant based listening in the social acoustic world. Building upon previous work by scholars who originally conceptualized the notion of auraldiversity, the paper identifies a list of creative propositions to serve as a guide to shape outcomes and participatory modes of engagement using sonic arts practices. These include methods from sound art practitioners that have creatively dealt with affordances of sound to question normative listening, explore new aesthetics of sound, and blend collaborative processes with cognitive aspects of social listening through a collective elicitation of auditory imagery. By diversifying the process of designing auditory displays, we can challenge and contrast traditional models of testing for the ’ideal’ ear, to re-route auditory display research and design towards embracing hearing diversity. The paper invites the reader and the wider auditory display community to frame more such opportunities to adopt participatory methodologies for designing sonification for aural diversity.

Authors:   Faculty of Social Sciences and Liberal Arts, UCSI University, Kuala Lumpur, Malaysia, Rui Yang , Attan Sri Azra ,   Faculty of Social Sciences and Liberal Arts, UCSI University, Kuala Lumpur, Malaysia
Published: October 2024

This study investigated the factors that affect digital literacy among university students in Beijing, focusing on how socioeconomic status, access to technology, educational programs, and the learning environment play a role. A quantitative method was used to collect data from 391 students at five universities through a structured questionnaire. The data were analyzed using structural equation modeling. The results show that although socioeconomic status and access to technology are important, educational programs have the most significant impact on improving digital literacy. Interestingly, the learning environment did not have a major direct effect on digital literacy, but the study found that simply providing digital tools is not enough without proper instructional support. This research points to key areas for policymakers and educators to focus on to improve digital literacy in higher education, highlighting the need for coordinated educational strategies that make full use of technology. The findings suggest further research is needed to understand how digital tools are used in learning environments and their long-term impact on students’ digital skills, with the goal of improving educational practices and policies for the digital era.
Health Locus of Control and Medical Behavioral Interventions: Systematic Review and Recommendations
Authors: Mozafari Sogol , Yang Alan , Talaei-Khoei Jason
Published: October 2024

Background

Health locus of control (HLOC) is a theory that describes how individuals perceive different forces that influence their lives. The concept of a locus of control can affect an individual’s likelihood to commit to behaviors related to their health. This study explores the literature on the relationships between HLOC and medical behavioral interventions.

Objective

This study aims to better understand how HLOC constructs can potentially affect patient responses to health behavioral interventions and to propose a series of guidelines for individuals interested in designing medical behavioral interventions related to HLOC.

Methods

We used the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) methodology and performed an analysis of 50 papers related to the topic of HLOC and medical behavioral interventions. Inclusion criteria were studies that had a behavioral intervention involving patients and contained a metric of at least 1 of the constructs related to HLOC. The initial screening and search were conducted by 2 researchers (AY and SM) separately. The results were then combined and compared.

Results

Our findings explore the influence of different levels of HLOC along with the importance of both patient- and health-related context when assessing the relationships between HLOC constructs and the likelihood of health behavior change. The findings show that different constructs related to HLOC can act as reliable predictors for patient responses to medical behavioral interventions. Patients who score higher on internal HLOC measures are more likely to exhibit behaviors that are consistent with positive health outcomes. Patients who score higher on chance HLOC are more likely to exhibit behaviors that may lead to adverse health outcomes. These conclusions are supported by most of the 50 studies surveyed.

Conclusions

We propose guidelines for individuals designing medical behavioral interventions so that they can make use of these relationships linked to HLOC. The three guidelines suggested are as follows: (1) in most situations, improving internal HLOC will improve health outcomes for patients; (2) patients with high external HLOC should be further studied to determine the source of the external HLOC; and (3) patients with a high chance HLOC are less likely to follow preventative behaviors or be responsive to interventions. Limitations of the study are that the primary search and analysis were conducted by 2 principal researchers (AY and SM). Interpretation and development of the guidelines are subject to individual interpretation of results and may not be applicable to all contexts.

Published: October 2024

Background

Menstruation is a physical symptom that occurs in women of reproductive age. It has a significant impact on the daily life and health of women when their academic and social activities are most active. Since many women experience difficulties in daily life because of premenstrual syndrome and dysmenorrhea, it is important to identify, prepare for, and manage the menstrual cycle in advance.

Objective

This study aimed to investigate the relationship between menstruation-related experiences and the use of mobile-based period tracker apps by millennial and generation Z (gen Z) individuals. The objectives of this study are to investigate (1) menstrual cycle management, (2) factors affecting app usage (3) factors affecting cycle management, and (4) motivators and barriers to using period tracker apps, in millennial and gen Z women.

Methods

A mixed methods design was used for this study. The participants were young women aged 20-39 years and recruited via the Ovey application. Data were collected through surveys and focus group interviews. The survey was conducted among 700 women, and 8 of them participated in the focus group interviews.

Results

In total, 431 (62.3%) participants used period tracker apps primarily to predict their next menstrual cycle. Factors affecting app usage included childbirth experience (odds ratio [OR] 0.475, P<.05), number of dysmenorrhea symptoms (OR 1.136, P<.05), and cycle management level (OR 2.279, P<.001). Additionally, education level (OR 1.122, P<.05 [university level compared high school level]) and the number of dysmenorrhea symptoms (OR 1.024, P<.05) showed a positive association with the cycle management level. However, childbirth experience (OR 0.902, P<.05) and period irregularity (OR 0.929, P<.001) were negatively associated with the cycle management level.

Conclusions

Period tracker apps are becoming the new normal among millennials and gen Z individuals for managing their menstrual cycles. The use of a period tracker app empowers women by helping them gain a better understanding of their bodies, ultimately enhancing their social, academic, and health-related lives. Improving the accuracy and literacy of the app is an ongoing task for period-tracking apps, and it is important to provide added value tailored to users’ needs. Therefore, the findings of this study should be considered when designing or upgrading period tracker apps to facilitate the adoption of digital technology among young women, thereby promoting their overall well-being and reproductive health.

Authors: Kepadisa Keeletse Katlego , Yin Gan
Published: October 2024

Abstract: Load shedding is now occurring in South Africa due to power outages. One of the most important issues facing the nation is still load shedding, which has a negative impact on daily business operations and forced some small enterprises to close. Numerous companies were impacted by the power irregularity issue. This was the beginning of the end for a number of enterprises. To stay afloat, several businesses were forced to close or cut back on staff and inventory. Despite warnings about the frequency of load shedding, some businesses were nevertheless severely impacted since they could not afford other options. The decline in South Africa's economy had an impact on these firms. Because of their low turnover, load shedding created a hostile work climate for a number of enterprises, which in turn led to dissatisfied employers. Since big franchises are having trouble, micro, small, and medium sized businesses are having much greater trouble. Thus, comprehending the perceived psychological, social, and economic effects of load shedding on workers at particular small, medium, and micro businesses in South Africa was the main goal of the study.

Published: October 2024

Effective learning planning requires information on the obstacles to learning a given concept that students experience to create a learning flow that matches the students’ characters, including in the learning of the concepts of relations and functions. The research aims to determine the learning obstacles (LOs) that students experience in learning the concepts of relations and functions as per the criteria of the theory of didactic situations (TDS). Employing the case study method, this qualitative research was conducted with subjects that included 19 prospective teacher students who had taken a diagnostic test and participated in in-depth interviews. An analysis was conducted based on three TDS criteria, namely action, formulation, and validation. The results revealed two types of LOs that students experienced in learning the concepts of relations and functions: 1) ontogenic obstacles and 2) epistemological obstacles. The first type of obstacles included 1a) the inability to properly understand the definition of the intersection of two relations, referred to as conceptual ontogenic obstacle, and 1b) the inability to relate the concept of relations in drawing a Hasse diagram, referred to as instrumental ontogenic obstacle. Meanwhile, the second type included 2a) the difficulty in expressing relations in the forms of mapping diagrams and graphs, 2b) the difficulty in determining the range of ​​a function, 2c) the difficulty in identifying relations which are also functions, 2d) the inability to represent relations in the forms of mapping diagrams, and 2e) the inability to write a function as a set of ordered pairs. It is recommended that these LO findings be taken into consideration in designing learning tools.

Authors: Yarman Yarman , Yerizon Yerizon , Dwina Fitrani , Murni Dewi , Hevardani Kelly Angelly
Published: October 2024

Integral learning is particularly challenging for students, primarily due to misconceptions predominantly caused by students' lack of understanding about functions, limits, and derivatives. Therefore, this research aims to investigate students’ thinking processes when solving double integral using Action, Process, Object, and Schema (APOS) theory, with a focus on past errors. In order to achieve the objective, a descriptive qualitative method was adopted. Data was collected from tests, interviews, and relevant documentation, and tested for validity using triangulation methods. The obtained results showed that high-ability students understood APOS stages in solving double integral. However, at the object stage, a lack of thoroughness in simplifying algebra led to misunderstandings. Medium-Ability Student (MS) was observed to successfully reach APOS stages when solving double integral using polar coordinates. Low-Ability Student (LS), on the other hand, showed inadequate understanding at the process stage, as evidenced by the failure to correctly draw the area and set integral boundaries. During the course of this investigation, process errors were found to be commonly associated with the calculations of double integral. In order to address these issues, Genetic Decomposition (GD) should be designed for other calculus topics, and error classification expanded to enhance the effectiveness of lectures.

Published: October 2024

COVID-19 caused the learning process to change from a face-to-face learning process to a distance learning process by using various applications. However, this learning process is also considered less effective in math because students’ conceptual understanding is imperfect. The imperfection of this concept caused students to experience learning loss. This research aimed to analyze students’ learning loss in elementary schools in mathematics subjects. This research used a qualitative research design with a case study type of research. This research involved 280 fifth-grade students from 4 elementary schools. The research results showed that students experienced learning loss in understanding geometry and fraction concepts. Students cannot solve math problems if the problem contains two concepts at once. According to the students, they did not understand these three topics well because when studying these topics, they carried out a distance learning process. Based on these findings, researchers concluded that students experienced learning loss in the high category, with 82% students affected. This study highlights the need for teachers to address learning loss that students experience in geometry and fraction materials. Thus, mathematics teachers can prepare learning tools to help students overcome learning loss.

This study explores how integrating Mobile Math Trails within the Problem-Based Learning (PBL) model can effectively support numeracy learning. This research was conducted using a design research method with an exploratory approach focused on the design experiment stage. The study involved eighth-grade students from SMP N 39 Semarang. Data was collected through observation, questionnaires, portfolios of students’ work, and interviews. The findings show that Mobile Math Trails-supported learning using PBL model can be an alternative numeracy reinforcement learning. The tasks design students explore around the school environment refers to numeracy indicators with specific content, context, and cognitive levels. The features embedded within the Mobile Math Trails application assist students in the problem-solving process. The tasks designed within the application foster a direct link between mathematical concepts and real-world scenarios within the school environment, thereby necessitating students' reasoning skills. Active student involvement is crucial in this learning, as collaboration among peers is essential for generating optimal learning experiences. Moreover, the learning steps outlined in the research necessitate students' physical engagement. Future studies could explore the application of numeracy reinforcement learning facilitated by Mobile Math Trails in diverse environments.

In modern business conditions, the network interaction of organizations is one of the most effective forms of cooperation within the framework of the project. The ability of the network to adapt to changing factors and conditions of the external and internal environment based on the reactive management of business processes of project interaction ensures not only the achievement of project goals, but also the satisfaction of the complementary interests of all counterparties. The process of developing the author's model includes an analysis of existing models of network interaction between organizations, the study of methods and approaches to evaluating the effectiveness of such interaction, as well as the identification of key factors influencing the success of the project. The results obtained will improve the understanding of the processes of networking between organizations in the implementation of projects, as well as develop recommendations to improve the effectiveness of such interaction. The results can also be useful both for the scientific community and for practitioners involved in project management and business processes in a network context. The methodological basis of the study was the methods of comparative and logical analysis, induction and deduction, analysis and synthesis. As a result of the work carried out, the author's model of network adaptive interaction of organizations was formed in the conditions of decision-making by the dominant owner on the implementation of the project.

La cripta de la Catedral Metropolitana de San Salvador es un lugar de memoria, en ella hubo acontecimientos que marcaron la historia de El Salvador en la década de 1980. La cripta alberga los restos de san Óscar Arnulfo Romero y Galdámez, conocido como monseñor Romero, y con el tiempo se ha convertido en un espacio de reflexión. El presente artículo tiene el propósito de describir ese lugar de memoria, los elementos materiales e inmateriales que lo componen; ello, a través de la metodología de observación participante. El principal hallazgo en el estudio se encontró a través de los testimonios de los participantes de las liturgias y las mujeres y hombres que componen la comunidad, quienes argumentaron que el rol de la cripta para los salvadoreños es ser una ventana de denuncias, recuerdos y contradicciones.
Métricas esenciales del impacto cientifico de las revistas
Authors: Cortés Osorio Jimy
Published: October 2024

La evaluación de las revistas científicas ha sido objeto de intenso debate desde que Eugene Garfield introdujo el concepto del Factor de Impacto (FI) en 1955 [1]. Aunque la implementación práctica del FI no fue inmediata, su desarrollo estuvo fuertemente vinculado a la creación del Science Citation Index (SCI) en 1964 el cual fue desarrollado por el Institute for Scientific Information (ISI) bajo el liderazgo de Garfield, con lo que revolucionó la forma en que se analizaba la literatura científica.
