Authors: Kebede Azmeraw Ambachew , Taye Birhan Tsegaw , Wondie Kindu Yinges
Published: October 2022

Background

Despite the current sustainable development goal period (i.e. SDG 3), the prevention of maternal and neonatal mortality is not satisfactory in Ethiopia. Keeping women knowledgeable about antenatal care and maintaining a positive attitude towards its uptake, particularly in the marginalized rural community is crucial. However, evidence regarding the knowledge and attitude of women towards antenatal care uptake is scarce. Therefore, this study aimed to assess factors affecting comprehensive knowledge of antenatal care and attitude towards its uptake among women delivered at home in rural Sehala Seyemit district, northern Ethiopia.

Methods

A community-based cross-sectional study was conducted from September 1stto October 15th, 2020. A multi-stage sampling technique was used to select 653 women. The data were collected using a semi-structured interview guide. Data were entered into EPI INFO 7.1.2 and analyzed by SPSS version 25. Both bivariable and multivariable logistic regression analyses were undertaken to identify factors associated with women’s knowledge of antenatal care and attitude towards its uptake. The level of significant association in the multivariable analysis was determined based on a p-value of < 0.05.

Results

Women’s knowledge of antenatal care and positive attitude towards its uptake was 56.5% and 75.2%, respectively. Older age (AOR = 7.2; 95% CI: 3.43, 15.1), media exposure (AOR = 3.69; 95% CI: 2.41, 5.65), history of abortion (AOR = 11.6; 95% CI: 3.3, 14.6), time to reach health facility (AOR = 4.58; 95% CI: 3.05, 6.88), and history of obstetric danger signs (AOR = 7.3; 95% CI: 3.92, 13.64) were factors significantly associated with knowledge of antenatal care. Furthermore, higher decision-making power (AOR = 8.3; 95% CI: 4.8, 13.83), adequate knowledge of antenatal care (AOR = 2.2; 95% CI: 1.26, 3.71), delivery attended by health extension workers (AOR = 2.3; 95% CI: 1.1, 5.1), and media exposure (AOR = 2.27; 95% CI: 1.30, 3.97) were predictors of a favorable attitude towards antenatal care utilization.

Conclusion

Although the majority of women in the present study had a favorable attitude towards antenatal care uptake, their knowledge level was inadequate. Strengthening access to transportation, mass media, involvement in household decision-making, and encouraging women to deliver at a health facility by a skilled provider may increase women’s knowledge and attitude towards antenatal care uptake, thereby improving maternal healthcare service uptake.
Agroenvironmental narratives of transformative resistance: How participatory videos frame climate change in India
Authors: Ichplani Pooja
Published: October 2022

There is urgent need to consider prevailing environmental problems within the larger cultural contexts to effectively progress towards climate change impact reduction. However, national agenda to mollify the climate change rarely frames the crises from the diverse perspectives and experiences that India is home to. Shifting attention from the United Nations’ focus on perpetrators of climate change to climate change victims, this qualitative content analysis uses a constructivist paradigmatic approach to examine the participatory video narratives produced by local media producers in rural India. Based on the levels of analyses for the impact, findings from twenty primary issue videos are thematically presented: individual, family and community, and spatial. The videos depict an intertwined nature of agriculture and environment, and documents agentative social action, transformative collective potential, and present a starting point to catalyse an iterative process of communication that expands our understanding of climate change impact beyond what is portrayed in globally dominant narratives.
‘A long meandering slide’: Feminist critique, genderqueerness, sexual agency and Crip subjectivity in Stephen Dwoskin’s late works
Authors: Chamarette Jenny
Published: October 2022

Stephen Dwoskin was a prolific experimental filmmaker from the mid-1960s until his death in 2012. Commonly associated with the New York underground film scene and the London Filmmakers’ Co-Op, which he co-founded in 1966, Jewish-American Dwoskin was also a childhood survivor of polio and a disability rights activist. Though an enduring oral legacy of feminist criticism of Dwoskin’s work remains since the 1980s, Dwoskin’s later work from the 1990s and 2000s is acutely understudied. In this article, I recontextualize earlier feminist positions in light of the ‘cripping’ of sexuality and gender proposed by recent critical disability studies, applied to two of Dwoskin’s later works. Adopting archival evidence of feminist critique, feminist art histories and Crip approaches to sexuality, I examine androgyny and genderqueerness in Dwoskin’s photomontages from Ha, Ha! La Solution Imaginaire (1993) and conflations of critical medical and BDSM-structured care in the film Intoxicated by My Illness (2001). I conclude that Dwoskin’s work invites rich epistemological re-evaluation of both feminist critique and entrenched sociocultural conceptions of gendered subjectivity, intimacy and sexual agency.

Published: October 2022

Gastric siderosis is the deposition of excess amount of iron from oral ferrous sulfate supplements to the gastric mucosa. It is an often overlooked entity in the literature and can be related to symptoms such as dyspepsia, nausea, and melena through mucosal injury. Different etiologies of gastric siderosis display distinct histopathological patterns. Pattern B, which is most commonly associated with oral iron supplements, is seen when iron is deposited in the extracellular space of the lamina propria. It is crucial to consider gastric siderosis as a potential diagnosis in symptomatic patients and to evaluate the necessity of oral ferrous sulfate supplements.

Published: October 2022

The education industry is a far-reaching, innovative and rapidly evolving field of business. To ensure success and integrity in the education industry, organisations and companies strive to deliver high-quality products and services in an efficient and ethical manner. Education research plays an important part in the education industry by underpinning product and service developments, and through illustrating impact. Organisations and companies also share these research claims when marketing to potential customers and investors. However, there can sometimes exist a disjunction between those conducting research and those responsible for interpreting the research for the purpose of public dissemination. This article first investigates what constitutes an education research claim. The risks associated with such claims are then identified and a review process suggested so educational bodies can ensure accuracy and ethicality in their claims. Adopting a case study approach, educational claims-making is contextualised from the stance and perspective of a typical international awarding organisation.
Maximizing the Number of Spatial Nulls with Minimum Sensors

Published: October 2022

In this paper, we attempt to unify two array processing frameworks viz, Acoustic Vector Sensor (AVS) and two level nested array to enhance the Degrees of Freedom (DoF) significantly beyond the limit that is attained by a Uniform Linear Hydrophone Array (ULA) with specified number of sensors. The major focus is to design a line array architecture which provides high resolution unambiguous bearing estimation with increased number of spatial nulls to mitigate the multiple interferences in a deep ocean scenario. AVS can provide more information about the propagating acoustic field intensity vector by simultaneously measuring the acoustic pressure along with tri-axial particle velocity components. In this work, we have developed Nested AVS array (NAVS) ocean data model to demonstrate the performance enhancement. Conventional and MVDR spatial filters are used as the response function to evaluate the performance of the proposed architecture. Simulation results show significant improvement in performance viz, increase of DoF, and localization of more number of acoustic sources and high resolution bearing estimation with reduced side lobe level.
Wideband Radar Cross Section Reduction of Microstrip Patch Antenna using Polarization Converter Metasurface
Authors: Patel Krunal , Joshi Manjusha
Published: October 2022

Antenna is the key device of communication on stealth platform. It is the greatest contributor to the overall RCS. So, it is desired to reduce the radar signature of the antenna. In this paper, a novel antenna is designed using polarization converter metasurface. The polarization converter metasurface converts the polarization of the incident wave into its orthogonal component. This PCM structure is loaded around patch antenna to reduce the RCS of the antenna over wide frequency range. With this novel design, the overall RCS reduction bandwidth of 140.57%  is obtained for the frequency range of 3.49 GHz – 20 GHz. In addition to this, the 10 dB RCS reduction bandwidth is obtained for the frequency ranges of 8.84 GHz – 10.42 GHz (16.41%) and 16.99 GHz – 17.81 GHz (4.71%). The design shows excellent angular stability for both TE and TM polarization. Discernible Bistatic Radar Cross Section reduction is obtained over a wide frequency range. Simulation and experimental results show that there is no degradation in antenna radiation pattern and other parameters. So, with this novel design the problem of obtaining wideband RCS reduction of a microstrip patch antenna is addressed without degradation in radiation pattern along with excellent angular stability for both the polarization modes.

Published: October 2022

Satellite-based positioning field of research is growing rapidly as there is an increase in demand for precise position requirements in various civil and commercial applications. There are many errors that affect the GNSS signals while propagation from satellite to receiver, which eventually induces errors in pseudo-range measurements. In order to assess the receiver characteristics for a specific error condition, the real-time signals may not be appropriate, and it is challenging to perform repeated experiments with the same error condition. The advantage of the GNSS simulator is that users can model the different scenarios for any given location on the globe, which are repeatable at any point of time. The conventional hardware simulators are expensive and have few limitations. In this paper, a reconfigurable hybrid simulator is proposed with some advantages over traditional hardware simulators, such as low cost, reconfigurability, and controllability over fundamental parameters. It can be able to record intermediate stage data, which makes it more suitable for the GNSS research field. The proposed multi-GNSS simulator considered implementing IRNSS-L5, IRNSS-S1, and GPS-L1 band signals. A general-purpose computer can perform the necessary calculations for signal generation. The hybrid simulator can be able to generate the digital I/Q data, which can be stored as I/Q data or can be connected to a general-purpose SDR (Software Defined Radio) for RF signal generation (bladeRF in this case). The I/Q data can be used with the software receiver to analyse the receiver performance concerning the specific error. The generated GNSS signals are validated with software and hardware receivers, and the obtained position is observed as expected.
A Design of Experiments Approach Towards Desired Flow Distribution Through Manifolds in Electronics Cooling
Authors: Annapurna Sogunuru , Varughese Suma , Niranjanappa AC , K Hemachandra Reddy
Published: October 2022

For rack-mounted electronics, flow distribution is desired as per the heat load characteristics. In the literature, attainment of flow uniformity through manifolds is highlighted and widely discussed as it has more applications. To attain desired flow distribution, the complexity of the problem increases. In the present paper, the Design of Experiments (DOE) along with response surface optimization is used to arrive at desired flow, which includes uniform flow also. A three-dimension, 10-channel Z-type manifold is considered for the study. This model is taken from experimentally verified and published data for which desired flow patterns are achieved. Flow requirement through each channel is set as a parameter for optimization and by the defined sample set under DOE, uniform flow and pattern flow are achieved by introducing suitable orifices. Multi-Objective Genetic Algorithm (MOGA) is used for obtaining orifice diameters. A good agreement is observed between the attained flow patterns and desired patterns. This approach is simple and can be implemented for industrial applications.

Published: October 2022

The article provides a comparative assessment of various ways of powering a synchronous motor with permanent magnets (PMSM) in the mode of a thyratron motor (TM). Numerically, on analytical and computer models, mechanical ω = f(M), the dependence of speed on electromagnetic torque, and energy ηэ = f(M), the dependence of elec-tromagnetic efficiency are calculated from the moment, the characteristics of the motor with sinusoidal power supply and discrete switching with different values of the relative inductance of the winding. Moment pulsations are investigated. The three most common methods of discrete degree commutation are considered – 120, 180 and 150. It is shown that discrete 120 degree commutation provides the highest value of ηэ in comparison with other methods, and the mechanical character-istics are approximately the same in appearance with different power supply methods. The study of moment pulsations has shown that discrete switching without additional measures cannot compete in this indicator with the case of sinusoidal power supply, which theoretically has zero moment pulsations. However, the use of 150 degree commutation makes it possible to significantly reduce them, bringing them closer to 2…3 %. Curves are given that allow an approximate estimate of the expected moment pulsations for all discrete switching methods. Practical recommendations on the choice of the method of powering the PMSM are given.

Published: October 2022

The aim of this research is the design of improved control algorithms for ladle furnaces, considering arc length adaptation to different argon blow conditions and slag layer depth. The paper considers the issues of optimizing asymmetric arc burn-ing regimes, which ensure the maximum reduction in radiation and an increase in thermal efficiency in phases located near the liquid metal mirror during bottom blowing and emergency lance operation. The experimental results of liquid bath sur-face behavior in dependence from blowing intensity and slag layer depth are presented. On the basis of experimental re-sults, new algorithms of electric modes control in ladle furnaces are proposed. These algorithms allow dynamic adaptation of electric arc lengths to different argon blowing modes and slag layer depth to be provided. Applying of this algorithm al-lows the requisite conditions for improving of different quality indicators in ladle furnace to be ensured, since the correct adaptation of electric mode to varying conditions of melting has a direct con-nection with thermal efficiency of electric arcs and efficiency of equipment in general.

Bezpieczeństwo czynne jest jednym z najważniejszych czynników decydujących o rozwoju współczesnych samochodów. Obecne pojazdy są coraz bezpieczniejsze, ale także zapewniają coraz lepsze osiągi. Warunki drogowe występujące podczas jazdy są często różne i zmienne, podobnie jak zmieniać się może rozkład masy na osie pojazdu w zależności od rozłożenia ładunku. Typowy samochód osobowy ma cztery koła, za pomocą których przenoszone są na drogę siły wzdłużne i poprzeczne. W niniejszym artykule pokazano wpływ rodzaju nawierzchni i warunków atmosferycznych na graniczne siły na kołach pojazdu. Do tego celu wykorzystano metodę Dynamic Square Method (DSM). Pozwala ona na wyznaczenie maksymalnych sił wzdłużnych na kołach pojazdu dla danego przyspieszenia poprzecznego. Metoda DSM zapewnia uzyskanie charakterystyk w postaci izolinii o stałych wartościach przyspieszeń poprzecznych uzyskiwanych dla konkretnych wartości sił wzdłużnych na kołach jezdnych. Charakterystyki mieszczą się w polu ograniczonym czworokątem, od którego prawdopodobnie wywodzi się nazwa metody. Analizując uzyskane charakterystyki można określić, jaki wpływ na wartości sił wzdłużnych na kołach pojazdu ma zmiana wartości współczynnika przyczepności przylgowej.
The impact of the transportation route on the price for the realized transport
Authors: Hernandez Salvador , Hammer Juraj
Published: October 2022

The price for the transport is determined by the carriers based on the costs incurred when the carriers transporting. Carriers are currently able to identify variable costs, the height of which changes with the change in the realized output and also fixed costs, which are dependent on the operating time of the means of transport. Carriers have the differences in the cost of the shipment for each destination they judge through the differences in charges for the use of the road network. It is also necessary to consider the possibility to backhaul transportation the vehicle for concrete transportation. The aim of this article is to verify the hypothesis, whether the change of the transport route is affected at the carrier's expense and in case, that is to quantify the impact of the transport route to the price for the transport carried out. We assume the effect of changing the shipping route also changes over time, therefore, the goal of the contribution is to identify changes the impact of the shipping route on the price within one week and to identify whether changes are developing in individual countries in the same process. Research is conducted on the basis of a situation survey in 19 European countries over a period of more than 3 months.
Is Bilingual Education Desirable in Multilingual countries?
Authors: Yuki Kazuhiro
Published: October 2022

In many countries, people use their mother tongue in local business, but use the language of the former colonizer in national business. How much weight should be placed on teaching one’s mother tongue and the lingua franca is a critical issue in these countries. This paper develops a model to examine these issues theoretically. It is shown that balanced education of the two languages is critical for skill development of those with limited wealth. It is also found that balanced bilingual education yields higher earnings net of educational expenditure than lingua-franca-only education only when a country has favorable educational and technological conditions (productivity is reasonably high and education is reasonably effective) and only for those with adequate wealth. Policy implications of the results are also discussed.
Neighborhood hypergraph model for topological data analysis
Authors: Liu Jian , Chen Dong , Li Jingyan , Wu Jie
Published: October 2022

Hypergraph, as a generalization of the notions of graph and simplicial complex, has gained a lot of attention in many fields. It is a relatively new mathematical model to describe the high-dimensional structure and geometric shapes of data sets. In this paper,we introduce the neighborhood hypergraph model for graphs and combine the neighborhood hypergraph model with the persistent (embedded) homology of hypergraphs. Given a graph,we can obtain a neighborhood complex introduced by L. Lovász and a filtration of hypergraphs parameterized by aweight function on the power set of the vertex set of the graph. Theweight function can be obtained by the construction fromthe geometric structure of graphs or theweights on the vertices of the graph. We show the persistent theory of such filtrations of hypergraphs. One typical application of the persistent neighborhood hypergraph is to distinguish the planar square structure of cisplatin and transplatin. Another application of persistent neighborhood hypergraph is to describe the structure of small fullerenes such as C20. The bond length and the number of adjacent carbon atoms of a carbon atom can be derived from the persistence diagram. Moreover, our method gives a highly matched stability prediction (with a correlation coefficient 0.9976) of small fullerene molecules.
Hilfer fractional stochastic evolution equations on infinite interval
Authors: Yang Min , Zhou Yong
Published: October 2022

This paper concerns the global existence of mild solutions for a class of Hilfer fractional stochastic evolution equations on infinite interval (0, +∞), while the existing work were considered on finite interval. The main difficulties here are how to construct suitable Banach spaces, proper operator relations, and then how to formulate the new criteria to guarantee the global existence of mild solutions on the previous constructed spaces under non-Lipschitz conditions. We mainly rely on the generalized Ascoli–Arzela theorem we established, Wright function, Schauder’s fixed point principle, and Kuratowski’s measure of noncompactness to handle with the infinite interval problems. Moreover, we give two examples to demonstrate the feasibility and utility of our results.

A simple method for measuring the monofilament diameter of continuous filament yarn with high bending stiffness via synthetic laser imaging
Authors: Wang Xi , Liao Shiqin , Hu Lizhu , Xiao Pei , Du Peijian
Published: October 2022

The uniformity of the monofilament diameter plays a key role in the performance of continuous filament yarns and their subsequent products. However, traditional methods for measuring fiber or filament diameters focus on estimating the arithmetic mean data, and only part of the diameter data can be obtained. Additionally, most of these traditional methods require complex sample preparations, such as by making cross-sectional slice samples. This study intends to present a simple method for measuring almost all of the monofilament diameters in a single yarn. It is not necessary to make slice samples. After the yarn sample or fabric sample is taken and prepared, synthetic laser images can be obtained directly by scanning the cross section of the sample with a 3D laser scanning confocal microscope. According to the results of many experiments, more than 90% of the monofilament diameters of a single yarn can be measured. The result also shows that the difference in the diameter data between the traditional method and the synthetic laser imaging method is less than 2%. This method presents the differences between the majority of monofilament diameters, and the yarn clustering property can be evaluated by the sum of the monofilament diameters and the yarn cross-sectional area.
Theoretical analysis and optimization of sensing parameters of surface plasmon resonance sensor
Authors: Gaur Shiv Shankar , Singh Amit Pratap
Published: October 2022

The right combination of substrate and metallic layer is very important to optimize the sensing parameters of surface plasmon resonance (SPR) sensors. These parameters are sensitivity, full width half maxima (FWHM) and reflectance minimum (R
min) at resonance angle. It is shown in the present theoretical analysis that the right combination of substrate and metallic layer helps in reducing the number of layers in SPR multilayer structures without compromising the sensitivity of SPR sensors. The present study was performed on three layers and molybdenum disulfide (MoS2) based four layer SPR structures. Gold (Au) and silver (Ag) were used as metallic layers and dense flint (SF11) glass and barium flint (BAF10) glass were used as substrate material. The best sensitivity value was achieved with the combination of Au and BAF10 in both three and four layer structure. The optimized values of FWHM and R
min were obtained using the combination of Ag and SF11 in both three and four layer structures.

A doença periodontal (DP) é consequência da atividade bacteriana e deposição de cálculo dentário, causando danos teciduais e processo inflamatório na cavidade oral. É uma enfermidade que atinge mais de 80% dos cães adultos e comumente está ligada ao aparecimento de doenças sistêmicas. A análise do estresse oxidativo sérico gerado na doença periodontal pode ser um biomarcador de lesão tecidual e agravamento da enfermidade. Este trabalho teve como objetivo a quantificação da peroxidação lipídica (TBARS) e da capacidade antioxidante total (TEAC) sérica de cães com periodontite. Os testes foram realizados em um grupo de cães saudáveis (n = 9) e um grupo de cães com DP severa (n = 8). Após a realização dos ensaios de metabolismo redox nos cães com DP, estes animais passaram por procedimento cirúrgico, remoção de cálculo dentário e medicação pós-cirúrgica de 10 dias, que incluía antibioticoterapia com amoxicilina e clavulanato de potássio e meloxicam como medicação anti-inflamatória. Após 30 dias da cirurgia, os animais foram novamente avaliados. Os resultados mostraram que houve um aumento significativo da peroxidação lipídica (43,81%) e uma diminuição da capacidade antioxidante total (8%) nos cães com DP. Após o tratamento, não houve redução dos níveis de estresse oxidativo, mas observou-se um aumento (8%) da capacidade antioxidante total. Estes dados colaboram para o melhor entendimento do metabolismo redox decorrente dos processos infecciosos e inflamatórios característicos da DP. O estudo demonstrou que o estresse oxidativo está presente na doença periodontal em cães, e apesar da não redução do dano oxidativo em 30 dias, a capacidade antioxidante total sérica, que estava diminuída, foi restaurada.

Published: October 2022

It is well known that recent sensory experience influences perception, recently demonstrated by a phenomenon termed “serial dependence.” However, its underlying neural mechanisms are poorly understood. We measured ERP responses to pairs of stimuli presented randomly to the left or right hemifield. Seventeen male and female adults judged whether the upper or lower half of the grating had higher spatial frequency, independent of the horizontal position of the grating. This design allowed us to trace the memory signal modulating task performance and also the implicit memory signal associated with hemispheric position. Using classification techniques, we decoded the position of the current and previous stimuli and the response from voltage scalp distributions of the current trial. Classification of previous responses reached full significance only 700 ms after presentation of the current stimulus, consistent with retrieval of an activity-silent memory trace. Cross-condition classification accuracy of past responses (trained on current responses) correlated with the strength of serial dependence effects of individual participants. Overall, our data provide evidence for a silent memory signal that can be decoded from the EEG potential, which interacts with the neural processing of the current stimulus. This silent memory signal could be the physiological substrate subserving at least one type of serial dependence.

SIGNIFICANCE STATEMENTThe neurophysiological underpinnings of how past perceptual experience affects current perception are poorly understood. Here, we show that recent experience is reactivated when a new stimulus is presented and that the strength of this reactivation correlates with serial biases in individual participants, suggesting that serial dependence is established on the basis of a silent memory signal.
Autopolyploidy & Allopolyploidy Card Sort
Authors: Strandberg Stacey
Published: October 2022

Biological terms describing abnormal numbers of chromosomes, such as polyploidy, eupolyploidy, aneuploidy, autopolyploidy, and allopolyploidy, can be confusing to students. A card-sorting activity designed to expose high school students to these key terms used in the evolution and genetics units of biology classes allows them to visualize these concepts. Students work with classmates to organize key terms with matching definitions and diagrams. The activity will solidify students’ knowledge and understanding about different chromosomal abnormalities that can result from nondisjunction occurring in meiosis or from mating with different species, which may lead to sympatric speciation. The culmination of the activity includes students using their inquiry-based skills to investigate mystery plant and animal cards and determining if they are autopolyploid or allopolyploid organisms.
Implementing the FrogWatch USA Citizen Science Program as a Versatile Ecological Educational Tool

Published: October 2022

Citizen science programs, like FrogWatch USA, offer simple training guidelines to collect field data, which provides records across broad geographical locations, allowing for the study of population trends on a large scale. Due to the relative ease of implementing the protocol, this program can easily be used in undergraduate and high school courses to provide an active learning environment and independent research opportunities. Here, we describe how FrogWatch USA call surveys were paired with traditional trapping surveys and conclude that call surveys can be useful in ecological monitoring. We suggest recommendations on how this program can be utilized in different settings and across disciplines.
Reflections on Sound Associations and Sonic Digital Environments
Authors: Pinheiro Sara , Rouš Jiří
Published: October 2022

This essay uses a “thought experiment” in order to combine theories of perception with sound practices. For that, it explores the concept of “object of thought” and the process of brain-associations in relation to acousmatic composition and reduced listening. Throughout the hypothetical premise of a falling tree, the study brings to discussion digital environments, in particular in relation to methodologies behind game engines. Eventually, it proposes to divide the question “If a tree falls in a forest and no one is around to hear it, does it make a sound?” according to its multiple angles—the falling tree, the tree of thought, the sound of the fall, and the tree in the digital environment—in order to arrive at the ultimate question: Is there a tree, did it fall, is there a forest, is there a sound?
Reflections from an Artist Researcher
Authors: Stuhl Andy Kelleher
Published: October 2022

Wave Farm is a nonprofit organization that sponsors and preserves transmission art—a category that the organization has defined wherein artists and artworks intervene in the electromagnetic spectrum as a creative medium. In this essay, Andy Stuhl reflects on Wave Farm’s 25-year history from two vantage points: as a researcher of recent American radio history in which Wave Farm has played an active role, and also as the 2021–22 Wave Farm Radio Artist Fellow. The Radio Artist Fellowship is a recent initiative by Wave Farm that has increased the organization’s role in archiving an artistic genre that previously lacked institutional support in the United States, and it has brought Wave Farm into greater contact with scholarly radio studies. Moving through the various phases of the nine-month fellowship, the essay pans out to show how radio studies, Wave Farm, and the radio medium as a whole have undergone significant and interconnected changes over the past 25 years.
“Developing Critical Listening”
Authors: Gregory Brian C.
Published: October 2022

The mid-1930s saw broadcasters, educators, and researchers coalesce around the study and implementation of critical listening for educational radio as a new technology for school instruction. These early media literacy researchers were motivated by ambitions to counter distracted and passive listening caused by commercial radio, advertising, and propaganda; to foreground the aural sense in classrooms dominated by reading and writing; and to promote democratic listening in young people. The following investigation draws from previously unexamined archival materials from research centers and radio schools of the air in Ohio and Wisconsin in addition to the oral history of Dorothy Gordon, progressive host of the Youth Forum educational program on New York Times–owned WQXR-AM. This article provides a critical perspective on the role of listening, sound technologies, and literacies for contemporary concerns about political polarization, tensions between commercial and noncommercial media, and democratic engagement.

This study seeks to describe the development of civil society. In the realm of political science, the role of civil society is one of the benchmarks for the development of democracy. In Indonesia, the transition period was marked by the collapse of Suharto's New Order, accompanied by the rapid growth of civil society. However, there has not been much research on the development of civil society in the local sphere. This research seeks to fill the gaps related to civil society development and democracy in the local sphere by focusing on Bali. The study used a qualitative method, particularly participant observation and interview. This study finds, first, the increasing tension between civil society actors and the state. Its shown in the state's efforts to limit the expression of civilian dissatisfaction with state policies. Second, the state's role is increasing in the life of civil society in Bali. In the context of Bali, Perda No. 4 of 2019 on Desa Adat shows recognition for indigenous peoples in Bali. The case of Bali displays the uniqueness of how the customs of the Balinese people, particularly in the civil society arena, influence the relationship with the state. It shows the inequality of power relations between the state and society. It confirms that tension between the state and civil society strengthened after policies that increased the state's intervention in civil society.
Is It Still in the Works? Understanding e-Government as A Stage in the Democratic Process
Authors: Tawakkal George Towar Ikbal
Published: October 2022

Democracy operates through the mechanisms of society. Today, technology has become an integral part of societal development, has permeated many aspects of life, and is expected to play an important role in democracy. The government, activists, and academics have all advocated for the use of technology in government, known as e-government. While there is academic debate about its impact on democracy, this article believes it is critical to place impact after development. This viewpoint is useful for engaging in academic debate. Assuming that each stage has its own timetable, this article asks, "What stage is e-government at right now?" Looking at the indicators measured by various agencies and positioning them as shared awareness of e-government, it is possible to conclude that today is the stage of e-government development. The answer may serve as a reminder to academics researching the impact of e-government.
Distribución del Liderazgo y Éxito Escolar: Análisis de Redes Sociales en Escuelas Chilenas
Authors: Bello Villablanca Juan Ricardo , López-Yáñez Julián
Published: October 2022

El liderazgo escolar es considerado un factor clave para la mejora escolar. Requiere movilizar a todos los miembros de la organización para involucrarlos y comprometerlos con el logro de sus objetivos. Este artículo persigue analizar la configuración del liderazgo escolar y la red de relaciones sociales predominantes en cinco centros educativos chilenos exitosos social y académicamente. Se administró un cuestionario de 9 ítems organizado en dos secciones, el perfil profesional de los informantes e información sobre las redes sociales en enseñanza, gestión, convivencia y asuntos personales. A partir de la información de las redes y la posición de los actores, se identificaron los patrones de liderazgo característicos de estos centros. Los datos fueron analizados mediante un enfoque mixto en dos fases. En la primera, las matrices de datos relacionales fueron examinadas mediante el análisis de redes sociales; en la segunda, los datos de entrevistas semiestructuradas, grupos focales y seguimiento a los directores se analizaron cualitativamente con el programa Atlas.ti. Los resultados indican las redes tienden en general hacia patrones de liderazgo focalizado, una baja densidad de relaciones y una centralización de las redes relativamente alta. Estos resultados aumentan la controversia predominante en la literatura especializada sobre el papel del liderazgo en el éxito escolar.
Sentimiento de Autoeficacia en Futuros Docentes: Revisión Sistemática en Iberoamérica 2015-2021
Authors: Bueno-Álvarez José-Antonio , Martín-Martín Margarita , Asensio-Muñoz Inmaculada
Published: October 2022

Partiendo del interés que en Educación existe por el tema de la autoeficacia, el objetivo de este trabajo es revisar las investigaciones realizadas en lengua española y portuguesa sobre el sentimiento de autoeficacia docente de los futuros profesores, desde el año 2015 hasta la actualidad, con el fin de contribuir a la mejora de la formación del profesorado desde la colaboración iberoamericana. Atendiendo a los principios de la metodología PRISMA, se revisan las bases de datos más comprensivas en este ámbito (Biblat, Dialnet plus, RedALyC, Scielo), seleccionándose finalmente 20 artículos, con la finalidad de hacer una investigación secundaria, que sintetice la investigación primaria realizada hasta el momento. A partir del análisis de los documentos identificados se describe el panorama actual de la investigación y se resumen los resultados, que indican que la formación práctica que recibe el futuro docente influye en su sentimiento de autoeficacia como profesional, que también depende de otras variables como experiencias previas, o el rendimiento. Se concluye acerca de la necesidad de hacer más efectiva la investigación con mejoras conceptuales, referidas a la definición del constructo; metodológicas, centradas en el diseño; y de enfoque, considerando los retos que surgen en el actual contexto de nueva normalidad.
Academia, Investigación y Pueblos Indígenas: Reflexiones desde una Experiencia de Diálogo de Saberes
Authors: Cubillos Froilán , Pérez Romina , Inostroza Xochitl , Pinto Diego , Pichihueche Roberto
Published: October 2022

El siguiente artículo recoge un conjunto de reflexiones que son fruto de una experiencia de diálogo de saberes en relación a la temática de educación indígena que nos ha llevado a pensar en el desarrollo de las ciencias sociales. Nos ha motivado el pensar qué hay de particular en la investigación con pueblos indígenas que distinga estas experiencias de otras vinculaciones académicas con territorios, así como qué puede ofrecer la Academia (o la Universidad) a los pueblos indígenas. Para ello, realizamos un breve recuento del marco histórico-teórico en relación al diálogo de saberes y luego reflexionamos sobre la relación entre Academia y comunidades a partir de nuestra propia experiencia, bajo una mirada crítica de algunos de los procesos que se han desarrollado en relación a esta temática en América Latina. Finalmente exponemos nuestra propuesta metodológica de investigación vinculada con comunidades indígenas en coherencia con los principios de la descolonización del saber y la justicia social basada esta última en el reconocimiento, en relación a proponer e impulsar la necesidad de interculturalizar las instituciones universitarias. Lo anterior, con miras a construir espacios académicos realmente dialógicos con las comunidades indígenas que permitan la valoración de distintas racionalidades, formas de ser y estar en el mundo.
La Experiencia de Estudiantes Universitarios en Situación de Discapacidad en Contexto Indígena frente a la Evaluación
Authors: Tejeda Cerda Pamela
Published: October 2022

La evaluación educativa para estudiantes en situación de discapacidad ha despertado gran interés tanto para investigadores y docentes en distintos niveles educativos, no obstante, la literatura científica se centra mayoritariamente en investigaciones y experiencias en contexto escolar.   En esta oportunidad la evaluación está orientada a explorar la disciplina desde aspectos incipientemente abordados: estudiantes universitarios en situación de discapacidad en contexto indígena.  Conocer de qué manera se construyen estas experiencias evaluativas en estos contextos, los efectos de la evaluación y la definición de propuestas para una evaluación más inclusiva y justa.  Corresponde a una metodología cualitativa, con un diseño de estudio de caso en estudiantes pertenecientes a dos universidades ubicadas en un contexto sociodemográfico indígena chileno. Como resultado se identificaron las formas de menosprecio, invisibilización, falta de apoyo y resiliencia.  Asimismo, las sugerencias son una formación docente en atención a la diversidad del aula, tiempo y entrega oportuna del material de estudio, gestión y política universitaria inclusiva y proactividad estudiantil.  Los resultados evidencian una necesidad de incorporar otros enfoques pedagógicos como el de justicia social, a las actuales evaluaciones que se utilizan en el trabajo con estudiantes en situación de discapacidad y con ello contribuir a procesos educativos justos e inclusivos.
