Level of Awareness on the Usage of Thermal Insulation among Building Professionals: Case of a Tropical City in Nigeria
Authors: Adegbie Morisade Omorinola , Hammed Yususf Olatunji
Published: March 2024

Adoption of buildings’ thermal insulation in Nigeria is still at the developmental stage; evidence of its usage for high thermal performance buildings and energy efficiency connotes a very low rate as there is very little evidence-based research in this regard. This paper seeks to evaluate the level of awareness on the usage of building thermal insulation among professionals in the building construction sector within Akure, a tropical city in Nigeria, to identify factors that deter its adoption and raise the level of commitment of the professionals within the building construction sector to sustainable practices of reducing buildings’ energy consumption. This is to create a resilient built environment against the challenges of climate change. Well-structured questionnaires were administered to gather data for the investigation. Jupyter Notebook version 6.4.12 was employed for the analysis. Results indicated a fairly good level of awareness among the building professionals while the barriers that affect the level of usage of thermal insulation within the study area are the high cost of procuring thermal insulation materials, non-compliance to building regulations, and governmental policy on construction. The research concluded that a good number of professionals have a high level of awareness of the usage of building thermal insulation, but the cost of the materials and government policy deterred its level of usage in the study area. Consequently, propagation of the usage of thermal insulation should be done through education and training of the stakeholders. Furthermore, the government needs to strengthen policies that support the usage and availability of thermal insulation within the study area

Published: March 2024

This study aimed to evaluate the effectiveness of the structured dietary intervention in reducing the risk of developing type 2 diabetes mellitus and improving associated metabolic health indicators. We included 530 participants randomly assigned to an intervention group with a Mediterranean-style diet and a control group with generic dietary guidelines. The incidence of type 2 diabetes mellitus was the primary outcome, whereas changes in fasting plasma glucose, lipid profiles, and body composition were the secondary outcomes. After 24 months, the incidence of type 2 diabetes mellitus was significantly lower among participants in the intervention group than those in the control group (P < 0.05). Fasting glucose, hemoglobin A1c, total cholesterol, and low-density lipoprotein levels were decreased (P < 0.05), and high-density lipoprotein levels were increased among participants in the intervention group than in those in the control group (P < 0.05). Also, body weight, blood pressure, and body mass index, major negative predictors of fasting glucose levels, were significantly decreased in participants in the intervention group than in those in the control group (P < 0.05), irrespective of other covariates. Dietary intervention substantially reduced the risk of developing type 2 diabetes mellitus and improved glycemic control, lipid profiles, and overall metabolic health.

Settlement, Climate Crisis and Lordship in Early Medieval Scandinavia
Authors: Fallgren Jan-Henrik
Published: March 2024

This article examines and describes the nature of lordship in Scandinavia during the Early Medieval period (c.400–1000 CE). It counters the assertions of earlier research, which claim that lordship with estates had already developed at the beginning of the period. Earlier arguments have built on assumptions that the development of estates was propelled by the ‘Dust Veil’ and the subsequent climate crisis of the mid-sixth century. Scholars have argued that a more hierarchical society followed, reflected through the emergence of more lavish burial customs. Through a broad comparison with other north-western European regions and peoples, this article demonstrates that these burial customs can be understood differently, and further, that a more hierarchal society was not necessarily the outcome of the crises of the sixth century. The resulting analysis of Scandinavian lordship is then anchored in a detailed case study of the well-preserved settlements, houses, farms and field-systems on the Baltic Island of Öland. It concludes that incentives to create estates in Scandinavia were not present before the Christianization process.
Unraveling The Relationship Between Kindergartners’ Fine Motor Skills with Their Numeracy Skills
Authors: Salas Genevee Gay Bongolto
Published: March 2024

Fine motor skills play a fundamental role in a kindergartner's development, serving as the building blocks for more advanced abilities. The purpose of this descriptive correlational study was to determine the influence of the kindergartners’ fine motor skills on their reading and numeracy skills. The study involved 54 kindergartners who were enrolled in a private school in Cagayan de Oro City, Philippines in the School Year 2022-2023. A checklist from Early Childhood was used to assess the fine motor skills of the kindergartners. A researcher-made instrument was also crafted to assess their numeracy. Frequency, mean, percentage, standard deviation and regression analysis were employed to analyse the collected data. The results revealed that the kindergartners’ fine motor skills need improvement, while the numeracy skills were good. Fine motor skills significantly influence the kindergartners’ numeracy skills indicating that kindergartners with better fine motor skills more likely exhibit good performance on their numeracy skills. The findings suggest that kindergartners have to progress and comprehend numerical concepts. Based on the result of the study, it is recommended that kindergarten teachers may provide remedial instruction or any intervention to assist kindergartners who perform poorly in numeracy skills.

AS MÚLTIPLAS CONCEPÇÕES DE MUSEUS NA HISTÓRIA: UMA BREVE REFLEXÃO SOBRE SEU PAPEL NA SOCIEDADE
Authors: Sousa Maria Ferreira De
Published: March 2024

A preocupação em preservar a história e a memória de um povo, uma sociedade, sempre esteve presente desde os tempos primórdios. Compreender como esse processo vem ocorrendo ao longo do tempo, das coleções de objetos da antiguidade à criação de gabinetes e aos museus atuais, constatando as múltiplas funcionalidades ocupadas nesse espaço em diferentes períodos da história, é objetivo deste artigo. Baseado em estudos realizados a partir de fontes bibliográficas e dados coletados do Centro de Pesquisa e Museu Regional de Arqueologia de Rondônia (CPMRARO), conclui-se que muitas mudanças ocorreram e vem ocorrendo no contexto dos museus. No Brasil, comumente, preservava-se objetos que representavam a história da nação, porém, não estava presente a história de grande parte da população, das populações negras, indígenas e àquelas que viviam à margem da sociedade. Privilegiavam-se os grandes monumentos e a história da elite. A memória era institucionalizada e manipulada, criavam-se mitos para reforçar o que deveria ser lembrado ou esquecido. Partindo de diversas críticas por parte da sociedade, os museus foram se modificando e ampliando seus espaços, novas definições e metas foram sendo estabelecidas. Um museu bem referenciado socialmente, precisa garantir em seu espaço diversas memórias,diversos grupos sociais estarem nele representado

THE SOUNDSCAPE IN MUSIC EDUCATION
Authors: Wilde Emma , Duarte-García M. A.
Published: March 2024

In this chapter we discuss a pedagogical model which employs the concept of soundscape as a fundamental element of the teaching-learning process to improve access to music education in rural areas of Michoacán, Mexico. The model was implemented in two areas in Michoacán in which students faced various barriers with regards to accessing music education as the areas had a lack of educational resources and the participants had no prior musical training. The pedagogical proposal was implemented in four stages. The first stage was the realization of listening exercises to explore the concept of soundscape. The second phase involved the creation of personal graphic notations. The third step was the realization of soundwalks and sound storyboards, and the final activity encompassed the use of graphic notation for creating soundscape compositions. The skills that the students developed when using soundscape as a pedagogical tool can be used as a base from which to introduce more complex musical theoretical concepts in future sessions and in higher educative levels. The pedagogical techniques outlined in this chapter could be used by any teacher regardless of their level of musical training and without the need to access expensive educational resources.

Objetivo: Este estudo busca descrever os impactos do diagnóstico e intervenção precoces no prognóstico de pessoas com Transtorno do Espectro Autista (TEA). Métodos: Trata-se de uma revisão integrativa de literatura, em que utilizaram-se os descritores “transtorno autístico” e “transtorno do espectro autista”, com o operador booleano “OR”, combinados ao descritor “diagnóstico precoce” pelo operador booleano “AND”, nas bases de dados Medline (Pubmed), LILACS e SciELO, em janeiro de 2024. Os critérios de inclusão foram artigos clássicos, ensaios clínicos, diretriz, metanálises, revisão sistemática, obtidos de forma gratuita e completa, publicados em português, inglês ou espanhol, no Brasil, a partir do ano de 2014, ordenados por relevância. Resultados: Dos 215 estudos encontrados, 168 foram provenientes do Pubmed, nenhum do SciELO e 47 do LILACS. Dos 11 analisados, 81% eram do Pubmed. As ferramentas diagnósticas variam muito, e o diagnóstico geralmente é feito somente após os 3 anos de idade, mas, apesar disso, alguns escores podem sinalizar sintomas do Transtorno do Espectro Autista, como o Cronograma de Observação Diagnóstica do Autismo (ADOS). Como meios de intervenção, encontrou-se cuidados comunitários habituais e o protocolo iBASIS-VIPP. Ao fim, os impactos na qualidade de vida refletiram na diminuição da gravidade dos sintomas. Conclusão: Apesar de o Transtorno do Espectro Autista ser mais diagnosticado após os 3 anos de idade, intervenções precoces antes dessa faixa etária podem refletir benefícios. No entanto, nota-se que os impactos a longo prazo das pessoas com diagnóstico do transtorno e com tratamento precoce precisam de maior elucidação.

Este ensayo explora la transición democrática del Perú post-Fujimori (2000-2023) a través de la filosofía de Albert Camus, enfocándose en los conceptos del absurdo y la revuelta. Desde la salida de Fujimori, Perú ha experimentado una serie de desafíos políticos y sociales, marcados por la corrupción y la inestabilidad, reflejando un profundo contraste entre las aspiraciones democráticas y la realidad política. A través del análisis de la era post-Fujimori, caracterizada por una mezcla de esperanza y desilusión, el ensayo ilumina cómo la continua búsqueda de orden y claridad en la política peruana choca con una realidad a menudo contradictoria y conflictiva. La elección de líderes como Pedro Castillo y la gestión de Dina Boluarte destacan la tensión entre las aspiraciones a una gobernanza racional y las realidades políticas, enfatizando la relevancia de los conceptos camusianos de absurdo y revuelta en el contexto de las luchas por justicia, transparencia y participación democrática en el Perú. Este análisis no solo problematiza la crisis actual, sino que también ofrece una reflexión sobre la naturaleza de la política y la sociedad en Perú, subrayando el potencial de la revuelta como medio para superar el absurdo y avanzar hacia una democracia más auténtica.
Schwartz Değer Kuramına Göre Kişilerin Değer Tipleri E-Ticaret Tüketici Davranışlarını Etkilemekte Midir?

Published: March 2024

Bu çalışmada, tüketici davranışını etki eden psikolojik etmenlerden değer kuramının e-ticaret tüketici davranışını nasıl etkilediği incelenmektedir. Araştırma verileri kolayda örnekleme yöntemi ile anket uygulanarak elde edilmiştir. Uygulama sonuçlarına göre bağımlı değişkenler olarak oluşturulan alışveriş sıklığı ve alışveriş tutarı değişkenlerinin güç ve geleneksellik değer tipleri ile anlamlı korelasyona sahip olduğu görülmüştür. Çok değişkenli regresyon analizi sonuçlarına göre, güç değeri alışveriş sıklığı ve alışveriş tutarı, geleneksellik değeri ise alışveriş sıklığı üzerinde açıklayıcılık gücüne sahiptir. Analiz sonuçlarına göre, güç değerinin alışveriş tutarı üzerinde negatif yönlü anlamlı bir ilişkisi olduğu sonucuna ulaşılmaktadır. Aynı şekilde, alışveriş sıklığı değişkeni ile de güç değişkeni negatif yönlü bir ilişki içerisindedir. Bu durum, güç değerine sahip kişilerin zamanı ve parayı daha iyi yönetme adına alışveriş yapma sıklıklarında azalma ve alışveriş tutarlarında daha tutumlu davranmaları ile açıklanabilir. Geleneksellik değerine sahip kişilerin; kültürel normlara uyma, saygı ve bağlılıkları, kişilerin yeni tüketim davranışına uyum içerisindeki tutumlarıyla bağımlı değişken olan alışveriş sıklığında pozitif yönde ilişki ile açıklanabilir. Araştırma sonucunda kişilerin değer tiplerinin e-ticaret tüketici davranışları üzerinde sınırlı ölçüde etkide bulunduğu kanısına ulaşılmıştır.

Published: March 2024

We estimate the mass of the Large Magellanic Cloud (LMC) using the kinematics of 30 LMC globular clusters (GCs). We combine proper motions measured with the Hubble Space Telescope, Gaia, or a combination of the two, from a recent study by Bennet et al. with literature line-of-sight velocities (LOSVs) to give three components of motion. With these, we derive a 3D velocity dispersion anisotropy

The Alpha-proton Differential Flow in the Alfvénic Young Solar Wind: from Sub-Alfvénic to Super-Alfvénic
Authors: Ran Hao , Liu Ying D. , Chen Chong , Mostafavi Parisa
Published: March 2024

Data obtained from Parker Solar Probe (PSP) since 2021 April have shown the first in situ observation of the solar corona, where the solar wind is formed and accelerated. Here, we investigate the alpha-proton differential flow and its characteristics across the critical Alfvén surface (CAS) using data from PSP during encounters 8–10 and 12–13. We first show the positive correlation between the alpha-proton differential velocity and the bulk solar wind speed at PSP encounter distances. Then we explore how the characteristics of the differential flow vary across the CAS and how they are affected by Alfvénic fluctuations including switchbacks. We find that the differential velocity below the CAS is generally smaller than that above the CAS, and the local Alfvén speed well limits the differential speed both above and below the CAS. The deviations from the alignment between the differential velocity and the local magnetic field vector are accompanied by large-amplitude Alfvénic fluctuations and decreases in the differential speed. Moreover, we observe that V

Our results also reveal that in the sub-Alfvénic solar wind both protons and alphas show a strong correlation between their velocity fluctuations and magnetic field fluctuations, with a weaker correlation for alphas. By contrast, in the super-Alfvénic regime the correlation remains high for protons, but is reduced for alphas.
The Effect of Ultraviolet Photon Pumping of H2 in Dust-deficient Protoplanetary Disks
Authors: Komaki Ayano , Kuiper Rolf , Yoshida Naoki
Published: March 2024

We perform radiation hydrodynamics simulations to study the structure and evolution of a photoevaporating protoplanetary disk. Ultraviolet and X-ray radiation from the host star heats the disk surface, where H2 pumping also operates efficiently. We run a set of simulations in which we varied the number of dust grains or the dust-to-gas mass ratio, which determines the relative importance between photoelectric heating and H2 pumping. We show that H2 pumping and X-ray heating contribute more strongly to the mass loss of the disk when the dust-to-gas mass ratio is

⊙yr−1. In these dust-deficient disks, H2 pumping enhances photoevaporation from the inner disk region and shapes the disk mass-loss profile. We thus argue that the late-stage disk evolution is affected by the ultraviolet H2 pumping effect. The mass-loss rates derived from our simulations can be used in the study of long-term disk evolution.
On the Formation of Double Neutron Stars in the Milky Way: Influence of Key Parameters
Authors: Deng Zhu-Ling , Li Xiang-Dong , Shao Yong , Xu Kun
Published: March 2024

The detection of gravitational wave events has stimulated theoretical modeling of the formation and evolution of double compact objects (DCOs). However, even for the most studied isolated binary evolution channel, there exist large uncertainties in the input parameters and treatments of the binary evolution process. So far, double neutron stars (DNSs) are the only DCOs for which direct observations are available through traditional electromagnetic astronomy. In this work, we adopt a population synthesis method to investigate the formation and evolution of Galactic DNSs. We construct 324 models for the formation of Galactic DNSs, taking into account various possible combinations of critical input parameters and processes such as mass transfer efficiency, supernova type, common envelope efficiency, neutron star kick velocity, and pulsar selection effect. We employ Bayesian analysis to evaluate the adopted models by comparing with observations. We also compare the expected DNS merger rate in the galaxy with that inferred from the known Galactic population of pulsar-neutron star systems. Based on these analyses we derive the favorable range of the aforementioned key parameters.

Published: March 2024

We report the nulling and subpulse-drifting properties of PSR J1649+2533 with observations of the Five-hundred-meter Aperture Spherical Radio Telescope (FAST). The FAST observations reveal that the nulling fraction of this pulsar is about 20.9% ± 0.8% at 1250 MHz. The statistical study of the durations of the nulling and burst states shows that the burst states can persist for extended pulse periods, exceeding 100 periods in some cases, while the shortest lasts only a few pulse periods. The null states have a much shorter duration, with a maximum duration of less than 30 pulse periods. A comparative study between the pulse profiles of the first active pulse (FAP) and the last active pulse (LAP) shows that the pulse profiles of LAPs are stronger and wider than those of FAPs. An analysis of the two-dimensional fluctuation spectrum for the single-pulse stack indicates that the pulsar exhibits clear amplitude modulation and subpulse drifting. The periods are a P
3 = 2.5 ± 0.1 spin period and P
2 = 17.°0 ± 0.°5 at 1250 MHz, respectively. In addition, the multiband investigation shows that P
2 seems to increase with the increase of the observing frequency, i.e., P
2 ∝ ν
0.8±0.1. This seems to be caused by the increasing pulse-profile width with the frequency. The high-sensitivity FAST observations will enable a detailed understanding of the emission of this pulsar and provide important clues for theoretical studies of the radiation mechanism.

Published: March 2024

We conducted a simulation of H2SO4 vapor, H2O vapor, and H2SO4–H2O liquid aerosols from 40 to 100 km, using a 1D Venus cloud microphysics model based on the one detailed in Imamura & Hashimoto. The cloud distribution obtained is in good agreement with in situ observations by Pioneer Venus and remote-sensing observations from Venus Express (VEx). Case studies were conducted to investigate sensitivities to atmospheric parameters, including eddy diffusion and temperature profiles. We find that efficient eddy transport is important for determining upper haze population and its microphysical properties. Using the recently updated eddy diffusion coefficient profile by Mahieux et al., our model replicates the observed upper haze distribution. The H2O vapor distribution is highly sensitive to the eddy diffusion coefficient in the 60–70 km region. This indicates that updating the eddy diffusion coefficient is crucial for understanding the H2O vapor transport through the cloud layer. The H2SO4 vapor abundance varies by several orders of magnitude above 85 km, depending on the temperature profile. However, its maximum value aligns well with observational upper limits found by Sandor et al., pointing to potential sources other than H2SO4 aerosols in the upper haze layer that contribute to the SO2 inversion layer. The best-fit eddy diffusion profile is determined to be ∼2 m2 s−1 between 60 and 70 km and ∼360 m2 s−1 above 85 km. Furthermore, the observed increase of H2O vapor concentration above 85 km is reproduced by using the temperature profile from the VEx/SOIR instrument.

An efficient numerical technique for investigating the generalized Rosenau–KDV–RLW equation by using the Fourier spectral method
Authors: Alrzqi Shumoua F. , Alrawajeh Fatimah A. , Hassan Hany N.
Published: March 2024

In this article, the generalized Rosenau-Korteweg-de Vries-regularized long wave (GR–KDV–RLW) equation was numerically studied by employing the Fourier spectral collection method to discretize the space variable, while the central finite difference method was utilized for the time dependency. The efficiency, accuracy, and simplicity of the employed methodology were tested by solving eight different cases involving four examples of the single solitary wave with different parameter values, interactions between two solitary waves, interactions between three solitary waves, and evolution of solitons with Gaussian and undular bore initial conditions. The error norms were evaluated for the motion of the single solitary wave. The conservation properties of the GR–KDV–RLW equation were studied by computing the momentum and energy. Additionally, the numerical results were compared with the previous studies in the literature.
On the approximation of analytic functions by infinite series of fractional Ruscheweyh derivatives bases
Authors: Zayed Mohra , Hassan Gamal
Published: March 2024

This paper presented a new Ruscheweyh fractional derivative of fractional order in the complex conformable calculus sense. We applied the constructed complex conformable Ruscheweyh derivative (CCRD) on a certain base of polynomials (BPs) in different regions of convergence in Fréchet spaces (F-spaces). Accordingly, we investigated the relation between the approximation properties of the resulting base and the original one. Moreover, we deduced the mode of increase (the order and type) and the $ \mathbb{T}_{\rho} $-property of the polynomial bases defined by the CCRD. Some bases of special polynomials, such as Bessel, Chebyshev, Bernoulli, and Euler polynomials, have been discussed to ensure the validity of the obtained results.

Published: March 2024

The secure authentication of user data is crucial in various sectors, including digital banking, medical applications and e-governance, especially for images. Secure communication protects against data tampering and forgery, thereby bolstering the foundation for informed decision-making, whether managing traffic, enhancing public safety, or monitoring environmental conditions. Conventional visual cryptographic protocols offer solutions, particularly for color images, though they grapple with challenges such as high computational demands and reliance on multiple cover images. Additionally, they often require third-party authorization to verify the image integrity. On the other hand, visual cryptography offers a streamlined approach. It divides images into shares, where each pixel represented uniquely, thus allowing visual decryption without complex computations. The optimized multi-tiered authentication protocol (OMTAP), which is integrated with the visual sharing scheme (VSS), takes secure image sharing to the next level. It reduces share count, prioritizes image fidelity and transmission security, and introduces the self-verification of decrypted image integrity through asymmetric key matrix generators, thus eliminating external validation. Rigorous testing has confirmed OMTAP's robustness and broad applicability, thereby ensuring that decrypted images maintain their quality with a peak signal-to-noise ratio (PSNR) of 40 dB and full integrity at the receiver's end.
Research on dependent evidence combination based on principal component analysis

Published: March 2024

Dempster-Shafer evidence theory, as a generalization of probability theory, is a powerful tool for dealing with a variety of uncertainties, such as incompleteness, ambiguity, and conflict. Because of its advantages in information fusion compared with traditional probability theory, it is widely used in various fields. However, the classic Dempster's combination rule assumes that evidences are independent of each other, which is difficult to satisfy in real life. Ignoring the dependence among the evidences will lead to unreasonable fusion results, and even wrong conclusions. Considering the limitations of D-S evidence theory, this paper proposed a new evidence fusion model based on principal component analysis (PCA) to deal with the dependence among evidences. First, the approximate independent principal components of each information source were obtained based on principal component analysis. Second, the principal component data set was used as a new information source for evidence theory. Third, the basic belief assignments (BBAs) were constructed. As the fundamental construct of evidence theory, a BBA is a probabilistic function corresponding to each hypothesis, quantifying the belief assigned based on the evidence at hand. This function facilitates the synthesis of disparate evidence sources into a mathematically coherent and unified belief structure. After constructing the BBAs, the BBAs were fused and a conclusion was drawn. The case study verified that the proposed method is more robust than several traditional methods and can deal with redundant information effectively to obtain more stable results.

We numerically investigate the possibility of defining Stabilization-Free Virtual Element discretizations–i.e., Virtual Element Method discretizations without an additional non-polynomial non-operator-preserving stabilization term–of advection-diffusion problems in the advection-dominated regime, considering a Streamline Upwind Petrov-Galerkin stabilized formulation of the scheme. We present numerical tests that assess the robustness of the proposed scheme and compare it with a standard Virtual Element Method.
