Soil Properties and the Technical Efficiency of Paddy Production in Malaysia: An Application of Stochastic Frontier Analysis
Authors: Hafifi Maidin Mohd Khairul , Kamaruddin Roslina , Applanaidu Shri Dewi
Published: December 2023

This study investigates the impact of soil properties on technical efficiency in paddy production, focusing on Malaysia’s two main paddy granaries: KADA and IADA BLS. These granaries play a significant role in Malaysia’s paddy production. The research employed three different models, with productivity as the dependent variable. In models 1 and 2, standard physical inputs were used as independent variables. Model 3, however, augmented the inputs with the addition of soil property variables. The empirical results revealed significant impacts from fertiliser, pesticide and land inputs, with the exception of land in model 1, where its coefficient was not statistically significant. Additionally, soil pH and the calcium+magnesium/potassium ratio emerged as crucial factors affecting paddy productivity. Importantly, incorporating soil property variables into the analysis resulted in a relatively lower technical inefficiency estimate. These insights are invaluable for policy formulation, highlighting key inputs that can optimise paddy production. The study’s findings regarding soil properties are particularly relevant for refining strategies in national paddy development programs, emphasising the importance of sustainable soil management. Looking ahead, the study advocates for comprehensive technical efficiency estimations that account for all forms of heterogeneity, including weather conditions, to ensure more accurate and insightful assessments.
A Case of Schwannoma in the Interarytenoid Area Presenting as Papillomatous Mass
Authors: Moon Seong Kyu , Ko So Young , Kim Min A , Kim Seung Woo
Published: December 2023

Schwannoma is a type of benign neurogenic tumor which may be derived from the nerve sheath. It is common in the head and neck region, but it occurs relatively rarely in the larynx. The laryngeal schwannoma can occur in the false vocal cord, aryepiglottic fold and epiglottis etc. The typical feature of it is a round submucosal well-encapsulated mass, and papillomatous appearance of its surface is extremely rare. A 76-year-old male came to our clinic with voice change and globus sense. The rigid laryngoscopy showed round papillomatous mass in the interarytenoid area. We performed laryngeal microsurgery, and he was pathologically diagnosed as schwannoma. We report an interesting and didactic case that has an atypical feature of laryngeal schwannoma with relevant literature review.
A Case of Injection Laryngoplasty in a Patient With Delayed-Onset Aspiration Following Near Total Laryngectomy
Authors: Jung Soo-Jin , Lee Min Hyuk , Jin Sung Min , Lee Sang Hyuk
Published: December 2023

Near total laryngectomy (NTL) is a procedure that creates a biological shunt between the airway and the neopharynx. Compared to total laryngectomy, NTL shunt performed in a suitable patient gives the ability to phonate at will. However, NTL has a potential for leak due to the invagination of the shunt into the neopharynx. Injection laryngoplasty is a mini-invasive technique that aims to manage aspiration caused by iatrogenic surgical complications. The procedure consists of moving a patient’s vocal cord toward the midline by injecting augmentation material. Authors report a case of a 74-year-old female, who was previously diagnosed to supraglottic cancer and have gone through NTL 12 years ago. 11 years after surgery, she reported aspiration through the neopharynx. Injection laryngoplasty was performed to relieve the leakage and she underwent the procedure two times using Hyaluronic acid. After injection laryngoplasty, leakage moderately decreased and the patient reported alleviation of her symptoms.

Published: December 2023

Tracheobronchopathia osteochondroplastica (TO) is rare idiopathic abnormality with incidence of 0.2%–0.7% from bronchoscopy. TO is characterized by focal or diffuse development of osseous and/or cartilaginous nodule in the submucosa of the trachea and bronchial walls. Most of the cases are asymptomatic, and if present, they can be nonspecific and diverse, such coughing and wheezing. Bronchoscopy and radiographic studies are useful diagnostic tool and conservative therapy is needed for each symptoms. Author reports a case of 49-year-old male who presented with throat discomfort without any significant past medical history. A subglottic nodular lesion with ulceration was identified, and laryngeal microsurgery for biopsy was done to rule out Tb or subglottic malignancy. However, the histopathological findings were indicative of TO, then we consult for bronchoscopy to confirm the diagnosis. Bronchoscopy also revealed consistent findings with TO. The patient is currently under conservative management and observation, without the need for further surgical intervention.
A Short Review About Tone Deaf
Authors: Kim Choung-Soo
Published: December 2023

To become skilled in singing, one needs the ability to accurately perceive music and the capacity to vocalize it. Recognition of music can be distinguished by the perception of pitch and rhythm. Pitch perception is often determined by genetics and neurological differences, whereas rhythm perception is influenced more by environmental factors than genetics. Tone deafness, or amusia, can stem from difficulties in perceiving pitch or from an inability to sing despite accurate pitch perception, known specifically as “purely vocal tone deafness.” This condition involves a disconnect between perception and the act of singing. And this can also arise from problems in the memory of perceived musical notes. Tone deafness not only affects musical abilities but also impacts language processing and communication.

Authors: De Sousa Santos Ferreira Andressa , De Oliveira e Oliveira Iara , Joice dos Santos Inamara , Macedo Santos Thalia , Santos de Assis Vanessa
Published: December 2023

O Afroempreendedorismo ou Empreendedorismo Negro é um movimento que cresce com o apoio coletivo, traço histórico do povo preto, que nos últimos anos tem assumido uma proposta decolonial, constantemente atravessado por questões interseccionais que dificultam a vida, sobretudo, da mulher negra empreendedora. Este artigo objetiva descrever os resultados alcançados em duas edições do projeto de extensão sobre afroempreendedorismo feminino, financiado pelo Programa Afirma (PROAF/UNEB), observando as limitações e avanços, reiterados pelo relato de experiência de alunas bolsistas. Importa destacar que foi utilizado a Interseccionalidade como método analítico fundamental nas duas edições do projeto (CRENSHAW, 1989). Os resultados alcançados no edital nº 64/2020, no auge pandêmico, e do edital nº 73/2022, em andamento, apontam incentivo ao domínio teórico e metodológico, protagonismo em trabalhos científicos, participação em eventos e ações extensionistas. Por sua vez, os relatos de experiência das bolsistas, estruturados por meio de um formulário autoinstrucional, revelaram o impacto que o letramento racial e o olhar interseccional causaram nas decisões profissionais, acadêmicas e pessoais das discentes e das já graduadas. Em suma, a educação para as relações étnico-raciais na extensão possui uma função formadora na articulação entre saberes e conhecimento de atrizes e atores envolvidos.

Através de uma pesquisa narrativa (Galvão, 2005), chegamos a essa escrita, uma narrativa de si, que detalha a experiência escolar, a trajetória de vida e o percurso do ofício de ensinar de uma professora de História. Esta escrita tem por objetivo demonstrar que a escrita autobiográfica pode ser um objeto de análise sobre a construção do fazer docente. As leituras sobre as narrativas de si têm como base Bolsanello (2017), Passeggi (2011), Arfuch (2010), além das leituras sobre educação e o saber docente baseadas em Freire (1989, 1996) e Gatti et al. (2019), que ajudaram neste processo de pensar o percurso docente e as histórias que preenchem esta trajetória. A narrativa autobiográfica docente (escrita de si ou memorial acadêmico) possibilita observar como se constitui o fazer docente e quais as características, especificidades e dilemas perpassam a trajetória de vida da pessoa, sendo, portanto, um elemento muito rico de análise para o campo da formação docente.

Published: December 2023

O estado nutricional é um fator importante na relação da doença renal crônica e a morbimortalidade dos pacientes, tendo em vista que a diálise não supre todas as necessidades da ausência funcional dos rins. Dessa forma o objetivo desse estudo foi avaliar os fatores associados aos dados antropométricos de pacientes em terapia renal substitutiva. Estudo transversal, descritivo-analítico, realizado em uma clínica de hemodiálise com 187 participantes. Foram avaliadas variáveis sociodemográficas, clínicas e medidas antropométricas. A associação entre as variáveis categóricas foi avaliada pelo teste de Qui-quadrado de Pearson e Exato de Fischer, considerando p<0,05. Os dados foram analisados no programa SPSS, versão 21. A maioria dos participantes eram homens (56,1%) e a faixa etária mais frequente foi a não idosa (70,1%). A Hipertensão Arterial Sistêmica foi a comorbidade mais frequente (82,7%). Dentre os participantes, os idosos possuíam a maioria do índice de massa corpórea abaixo do valor de referência (41,7%; p-valor <0,001). A média da altura foi de 158 ± 7,9 cm para o sexo feminino e 167 ± 7,9 cm para o masculino. A média do peso seco foi 60,20 kg ± 11,7 para o sexo feminino e de 63,63 kg ± 11,5 para o masculino. No que tange a relação cintura-quadril, evidenciou-se uma frequência maior do sexo feminino com elevado risco cardiovascular (71,1%; p- valor <0,001). O estudo mostrou que a avaliação antropométrica dos participantes idosos e mulheres, independente do tempo em hemodiálise, está inadequada aos parâmetros de referência. Assim, torna-se necessário, a vigilância das equipes de saúde e gestores acerca da temática para melhores cuidados em saúde.
Blindness Challenging Melodrama in Your Eyes Tell (2020) and Blind Massage (2014)
Authors: Wang Xinyi
Published: December 2023

While blindness has been a recurring motif in melodramatic fiction films, this article argues that some contemporary East Asian films about blindness provide a template for challenging ableism and melodramatic conventions via textual analysis. Based on the work of Peter Brooks, Linda Williams, and other significant studies on melodrama and blindness, I first introduce three main characteristics of and gaps in melodrama (virtue, dichotomy, and the moral occult) while examining the connections between blindness and melodrama in East Asian film history. Then I explore how filmic representation in East Asian can question melodramatic conventions and disrupt the dichotomy between disability and non-disability by using the Japanese film Your Eyes Tell (2020) and the Chinese film Blind Massage (2014) as case studies. Your Eyes Tell begins to problematize the melodramatic dichotomy and ableism by attaching great importance to multiple senses, whereas Blind Massage emphasizes the diversity of blindness and challenges melodramatic patterns by representing the body, emotions, affect and sound in very specific ways.

Data Assimilation in Chaotic Systems Using Deep Reinforcement Learning
Authors: Hammoud Mohamad Abed El Rahman , Raboudi Naila , Titi Edriss S , Knio Omar M , Hoteit Ibrahim
Published: December 2023

Data assimilation (DA) plays a pivotal role in diverse applications,
ranging from climate predictions and weather forecasts to trajectory
planning for autonomous vehicles. A prime example is the widely used
ensemble Kalman filter (EnKF), which relies on linear updates to
minimize variance among the ensemble of forecast states. Recent
advancements have seen the emergence of deep learning approaches in this
domain, primarily within a supervised learning framework. However, the
adaptability of such models to untrained scenarios remains a challenge.
In this study, we introduce a novel DA strategy that utilizes
reinforcement learning (RL) to apply state corrections using full or
partial observations of the state variables. Our investigation focuses
on demonstrating this approach to the chaotic Lorenz ’63 system, where
the agent’s objective is to minimize the root-mean-squared error between
the observations and corresponding forecast states. Consequently, the
agent develops a correction strategy, enhancing model forecasts based on
available system state observations. Our strategy employs a stochastic
action policy, enabling a Monte Carlo-based DA framework that relies on
randomly sampling the policy to generate an ensemble of assimilated
realizations. Results demonstrate that the developed RL algorithm
performs favorably when compared to the EnKF. Additionally, we
illustrate the agent’s capability to assimilate non-Gaussian data,
addressing a significant limitation of the EnKF.
Automated Bedform Identification - A Meta-Analysis of Current Methods and the Heterogeneity of their Outputs
Authors: Scheiber Leon , Zomer Judith Yttje , Wang Li , Cisneros Julia , Llantoy Ronald Gutierrez , Lefebvre Alice
Published: December 2023

Ongoing efforts to characterize underwater dunes have led to a
considerable number of freely available tools that identify these
bedforms in a (semi-)automated way. However, these tools differ with
regard to their research focus and appear to produce results that are
far from unequivocal. We scrutinize this assumption by comparing the
results of five recently published dune identification tools in a
comprehensive meta-analysis. Specifically, we analyse dune populations
identified in three bathymetries under diverse flow conditions and
compare the resulting dune characteristics in a quantitative manner.
Besides the impact of underlying definitions, it is shown that the main
heterogeneity arises from the consideration of a secondary dune scale,
which has a significant influence on statistical distributions. Based on
the quantitative results, we discuss the individual strengths and
limitations of each algorithm, with the aim of outlining adequate fields
of application. Yet, the concerted bedform analysis and subsequent
combination of results have another benefit: the creation of a
benchmarking data set which is inherently less biased by individual
focus and therefore a valuable instrument for future validations.
Nevertheless, it is apparent that the available tools are still very
specific and that end-users would profit by their merging into a
universal and modular toolbox.
Unveiling the Dynamics of Mantle Plumes Initiated by Rayleigh-Taylor Instabilities: Impact of Layer-Parallel Global Flows
Authors: Roy Arnab , Ghosh Dip , Mandal Nibir
Published: December 2023

Mantle plumes arising from deep sources in the Earth are thought to have
played a critical role in determining the planetary geodynamics. The
plumes originate mostly from gravitational or thermochemical
instabilities at the core-mantle boundary, triggered by density
fluctuations due to thermal or chemical variations. Understanding the
initiation mechanics of such instabilities is key to comprehending the
formation of these deep-mantle plumes, reflected from hotspots scattered
around the globe. Previous studies have explained their growth within a
theoretical framework of Rayleigh-Taylor (RT) instabilities. However, a
critical aspect that has been largely overlooked is the potential
influence of layer-parallel global flows on the dynamics and initiation
processes of instabilities. The present study combines 2D finite element
particle-in-cell numerical simulations with a linear stability analysis
to show the impact of global flows on the growth kinematics of RT
instabilities in a thermal boundary layer at the core-mantle boundary.
The simulation results indicate that the global flow acts as a counter
factor to dampen their growth rates. At a threshold global flow velocity
the dampening effects completely suppress the instabilities, allowing
the entire system to advect in the horizontal direction. The stability
analysis also predicts a non-linear increase in the instability
wavelength with increasing global flow velocity. These new findings
imply that the spatial frequency of plumes can drop remarkably in
kinematically active regions of Earth’s mantle. This study finally
offers a possible explanation for unusually large spacing between major
hotspots in the light of instability mechanics under global flows.
Harnessing AOS Observations for Advanced Understanding of Cloud Radiative Fluxes Introduction
Authors: Mauceri Steffen , Barker Howard , Henderson David , Schmidt K Sebastian , Chen Hong , Villefranque Najda , Davis Anthony , Stephens Graeme
Published: December 2023

Understanding the complexities of cloud-sky radiative fluxes is crucial
for improving numerical predictions of climate change. NASA’s upcoming
Atmosphere Observing System (AOS) mission promises unprecedented
observations that will present an opportunity to enhance our
understanding of the role of clouds in modulating both Earth’s radiation
budget and climate sensitivity. AOS will utilize a series of active
(Radar, Lidar) and passive (Imaging multi-angle polarimeter)
instruments. The active instruments will provide vertically resolved
cloud and aerosol information over a narrow ground-track (shown in red
in the Figure below), while the passive instruments will cover a much
wider swath. The high spatial resolution of AOS (~1km)
will allow us to study clouds at the process level. While this will give
us the opportunity to gain new insights, it also provides an
unprecedented challenge to deliver satellite products at such a high
resolution at which horizontal photon transport cannot be neglected,
leading to biases in traditional cloud retrieval algorithms. To estimate
radiative fluxes over the whole swath, we propose to extrapolate the
vertical information from the active instruments to the across-track
passive observations using a scene construction algorithm. This
algorithm is evaluated using data from Large-Eddy Simulations and
synthetic imagery computed by radiative transfer models.
Active K-12 Pedagogies for Geosciences: Improving Student Learning about Topographic Maps and Landscapes using Hands-on Play and Drones
Authors: Mathews Adam J. , DeChano-Cook Lisa M. , Bloom Cynthia
Published: December 2023

Hands-on activities and geospatial technologies have been shown to
support students’ learning of basic geography and geoscience concepts
(i.e. topographic map reading and 3D visualization of landscapes) while
providing a fun factor to improve student engagement. The objective of
this research was to determine if and to what extent students’ learning
of these concepts can be improved through incorporation of hands-on play
with Play-Doh® and LEGO® and geospatial technologies, specifically
drones. The project team conducted six months of biweekly, collaborative
instruction at Comstock Middle School in southwest Michigan
incorporating in-class activities such as drawing mental maps, creating
contour lines of model landscapes in water boxes, constructing 3D
landscapes from 2D topographic maps, building and operating small
drones, observing drone flight and learning about geospatial data
creation from drone-collected aerial images, and more. Pre- and
post-test comparisons revealed a 14% increase in overall student
scores, which is a statistically significant difference and improvement
in student performance. Our instructional approach improved students’
knowledge of topographic mapping and landscape concepts. Beyond
providing a broad overview of our pedagogical approach as well as
specific curricula and lesson plans, we further outline challenges and
limitations.
Identifying climate impacts from different Stratospheric Aerosol Injection strategies in UKESM1
Authors: Wells Alice Florence , Henry Matthew , Bednarz Ewa M. , MacMartin Douglas G , Jones Andy , Dalvi Mohit , Haywood Jim M.
Published: December 2023

Stratospheric Aerosol Injection (SAI) is a proposed method of climate
intervention aiming to reduce the impacts of human-induced global
warming by reflecting a portion of incoming solar radiation. Many
studies have demonstrated that SAI would successfully reduce global-mean
surface air temperatures, however the vast array of potential scenarios
and strategies for deployment result in a diverse range of climate
impacts. Here we compare two SAI strategies - a quasi- equatorial
injection and a multi-latitude off-equatorial injection - simulated with
the UK Earth System Model (UKESM1), both aiming to reduce the
global-mean surface temperature from that of a high-end emissions
scenario to that of a moderate emissions scenario. Both strategies
effectively reduce global mean surface air temperatures by around 3°C by
the end of the century; however, there are significant differences in
the resulting regional temperature and precipitation patterns. We
compare changes in the surface and stratospheric climate under each
strategy to determine how the climate response depends on the injection
location. In agreement with previous studies, an equatorial injection
results in a tropospheric overcooling in the tropics and a residual
warming in the polar regions, with substantial changes to stratospheric
temperatures, water vapour and circulation. However, we demonstrate that
by utilising a feedback controller in an off-equatorial injection
strategy, regional surface temperature and precipitation changes
relative to the target can be minimised. We conclude that moving the
injection away from the equator minimises unfavourable changes to the
climate, calling for a new series of inter-model SAI comparisons using
an off-equatorial strategy.
Sensitivities of Large Eddy Simulations of Aerosol Plume Transport and Cloud Response
Authors: Dhandapani Chandru , Kaul Colleen M , Pressel Kyle G , Wood Robert , Kulkarni Gourihar
Published: December 2023

Cloud responses to surface-based sources of aerosol perturbation depend
in part on the characteristics of the aerosol transport to cloud base
and the resulting spatial and temporal distribution of aerosol. However,
interactions among aerosol, cloud, and turbulence processes complicate
the prediction of this aerosol transport and can obscure diagnosis of
the aerosols’ effects on cloud and turbulence properties. Here,
scenarios of plume injection below a marine stratocumulus cloud are
modeled using large eddy simulations coupled to a prognostic bulk
aerosol and cloud microphysics scheme. Both passive plumes, consisting
of an inert tracer, and active plumes are investigated, where the latter
are representative of saltwater droplet plumes such as have been
proposed for marine cloud brightening. Passive plume scenarios show a
spurious in-plume cloud brightening due solely to the connections
between updrafts, cloud condensation, and scalar transport. Numerical
sensitivities are first assessed to establish a suitable model
configuration. Then sensitivity to particle injection rate is
investigated. Trade-offs are identified between the number of injected
particles and the suppressive effect of droplet evaporation on plume
loft and spread. Furthermore, as the in-plume brightening effect does
not depend significantly on injection rate given a suitable definition
of perturbed versus unperturbed regions of the flow, plume area is a key
controlling factor on the overall cloud brightening effect of an aerosol
perturbation.
Significance Testing for Cross Correlation: A Critical Examination of Correlations between ENSO and GRACE-Derived Terrestrial Water Storage Variabilities
Authors: Gao Chunchun , Chao Benjamin F. , Tan Bing , Wu Xudong
Published: December 2023

The linear cross correlation to quantify statistical connections or
relationships finds wide applications in various geophysical and
geodetic fields. However, there remains a dearth of comprehensive
discourse regarding the significance testing for cross correlation,
which would serve to differentiate statistically meaningful outcomes
from those merely stemming from pure randomness. This study aims to
develop a significance testing method for cross correlation in both
white noise and red noise based on the -distribution within a rigorous
statistical framework, which enables the establishment of significance
tests for cross correlation as function of relative time shift within
specified ranges, as demonstrated by Monte Carlo experiments that we
perform. Via these results we critically examine the previously-claimed
significant correlations between ENSO (El Niño Southern Oscillation )
and the global terrestrial water storage variations derived from the
GRACE (Gravity Recovery and Climate Experiment ) satellite mission.

Imbalances in cortical excitation and inhibition (E-I) have been implicated in both autism spectrum conditions (ASC) and schizophrenia spectrum conditions (SSC). However, most studies investigate these clinical conditions independently, possibly due to the difficulty of obtaining comorbid clinical populations. As such, the current study investigated the relationship between performance in the orientation discrimination task “ODT” as a potential proxy for E-I balance and the autistic (as assessed by Autism Spectrum Quotient “AQ”) and schizotypal personality traits (as assessed by Schizotypal Personality Questionnaire-Brief “SPQ-BR”) in the general population. 87 healthy adult volunteers participated in the study. We found that high autistic personality traits are associated with enhanced performance in the oblique condition of ODT. In contrast, high schizotypal personality traits are associated with poor performance in the vertical condition of ODT. Such associations support the suggested disruption of cortical E-I balance in ASC and SSC.

This study aims to find out how active dynamic archive management includes creation, arrangement, use, and storage activities, as well as knowing the supporting and inhibiting factors in active dynamic archive management activities at SMAN 1 Babakan, Kabupaten Cirebon. This research uses a qualitative approach with descriptive methods. Data collection techniques were carried out in three ways, namely field observations, direct interviews, and literature studies. The informants specified in this study were archivists at the Administration Office of SMAN 1 Babakan. The results of this study indicate that active dynamic archive management at SMAN 1 Babakan is carried out in several stages, (1) creation and acceptance; (2) checking and filing; (3) storage; (4) maintenance and security; (5) use; (6) transfer and destruction of archives. Records management is carried out on a mixed principle (centralized and decentralized) where some archives are managed by the respective work units and some are managed at the central archives. The management of dynamic archives receives support from the school in the form of providing adequate archive management support facilities. Then the obstacle that is felt is in the competence of Human Resources which is still minimal because it is still very new, so that archive management is not fully in accordance with existing standards.

Teachers' Perceptions of Physics Scientific Argumentation Test Instruments Based on Modern Test Theory Using Question Modeling Through E-Learning Edpuzzle LMS
Authors: Sari Alda Novita , Viyanti Viyanti , Ertikanto Chandra
Published: December 2023

The study aims to understand teachers' perceptions of scientific argumentation test instruments in physics based on modern test theory using question modelling through Edpuzzle LMS e-learning. It employed a mixed method with a Sequential Explanatory Design. Data were collected through questionnaires and analyzed descriptively. Initially, it was found that 75% of teachers had not developed assessment instruments capable of optimally training students, resulting in 68% of students struggling to understand physics learning. Additionally, 54% of students reported having identified and solved complex physics problems using scientific argumentation, while 46% had not. Based on survey results, 95% of students and teachers agreed that assessment activities encourage scientific argumentation, indicated by identifying scientific issues and explaining scientific phenomena. Hence, there is a need for a physics scientific argumentation test model based on modern test theory. For future research, it is suggested to explore how integrating this test model in different educational settings impacts students' scientific argumentation skills and understanding of physics concepts.
