Published: November 2022

The method used to estimate the regression parameters in this study is the Bayes method. The steps in estimating the parameters of the linear regression model using the Bayes method are to determine the Likelihood function from the normal distribution density function, determine the Prior Non-Informative distribution from a normal distribution, then look for the Posterior distribution by switching the Prior distribution with the Likelihood function.Writing this thesis aims to determine the estimation of the parameters of the linear regression model with the Bayesian method approach. From the regression model generated by the OLS method, it was identified that there was one Outlier data. Outlier is a factor that influences parameter estimation in linear regression model. A model will be shown in an example data case by comparing the results of the Ordinary Least Square (OLS) method using R and the results of the Bayesian method using WinBUGS. It can be seen that the MSE value obtained from the Bayesian Method estimation is smaller than the MSE value obtained from the OLS Method estimate. The Mean Square Error (MSE) value obtained from the estimation of the OLS Method is 0.8469 while the Mean Square Error (MSE) value obtained from the estimation of the Bayesian MCMC Method is 0.3723. This shows that the Bayesian MCMC method is much better than the OLS method.

Authors: Zhukova L. E.
Published: November 2022

The article discusses the concept of «universal religion», as reflected in the works by the world-famous Indian philosopher Swami Vivekananda. A lot of thinkers all over the world paid sufficient attention to the problem regarding the search for religious unity in human society. This problem still remains actual. Prevention of conflicts between various religions requires knowledge of historical approaches used and suggested by great public figures to their solution. Therefore, the study of Vivekananda’s ideas of «universal religion» is of a paramount importance. The present article aims to study the understanding of the idea of a single religion for the mankind as expressed by the Indian philosophers. Special attention is paid to the ideas regarding the Divine role in the «universal religion» project. The research is based on the hermeneutic analysis of Vivekan anda’s presentations and letters seen in the context of views on the possibility of existence of different faiths unity in the era of the Bengali Renaissance and nowadays. The article shows the philosopher’s attempt to reconcile the religions of the world on the basis of ideas which comprised the impersonal God of Advaita Vedanta. The article is concluded by some thoughts and suggestions regarding the development of the «universal religion» project as a component of the globalization process in the modern society.
Archival data on Historical locations of the Asiatic Museum in the Kunstkamera building
Authors: Ivanov D. V.
Published: November 2022

The Asiatic Museum was the first specialized research centre for oriental studies in Imperial Russia. The successors of the Asiatic Museum are nowadays the Institute of Oriental Studies of the Russian Academy of Sciences (Moscow) and the Institute of Oriental Manuscripts of the Russian Academy of Sciences (St. Petersburg). The Asiatic Museum collection of coins was subsequently transferred to the State Hermitage and the collections of ethnographic artefacts were embedded into the collections of what is nowadays Peter the Great Museum of Anthropology and Ethnography (the Kunstkamera) of the Russian Academy of Sciences (St. Petersburg). Studying the history of the Asiatic Museum is therefore significant both for the history of oriental studies and the history of museums and special collections in Russia. The archival holdingds reveal that in the 1820s the Asiatic Museum collections were allocated in the west wing of the present Kunstkamera building and occupied only five rooms in the first floor. In the 1830s some of the Russian museums were reformed. The Asiatic Museum had to change its location: it occupied a hall in the first floor in the Kunstkamera. Later, in 1837, the items, which belonged to the ethnographic collection were transferred to the newly established Ethnographic Museum of the Academy of Sciences. Now they form an integral part of the collections of the Peter the Great Museum of Anthropology and Ethnography (the Kunstkamera).

The low ability of students’ mathematical representation has an effect on achievement in mathematics learning. Students find it difficult to understand what is known and asked, also are still not able to find a way out in solving the questions so many students find it difficult to solve the problems given in the form of story questions. Low self-confidence is also an influence on student success because self-confidence itself is self-confidence in doing tasks and choosing good, appropriate, and effective solutions. The purpose of this study was to analyze the mathematical representation ability of number material based on self-confidence. The subjects of this study were three class VIII junior high school students who were taken randomly. The data collection techniques in this study were tests, interviews, documentation, and questionnaires. The results of this study indicate that: (1) Respondents with a high self-confidence category can solve problems on the sub-indicators of making mathematical equations or models from other representations, making image representations to clarify problems and facilitate solving, making problem situations based on the data or representations provided; (2) Respondents with moderate self-confidence and low self-confidence categories can only solve the problem in the sub-indicator to create a problem situation based on the data or representation provided. Rendahnya kemampuan representasi matematis siswa berpengaruh terhadap prestasi dalam pembelajaran matematika. Siswa sulit memahami apa yang diketahui dan ditanyakan, juga masih kurang mampu mencari jalan keluar dalam menyelesaikan soal sehingga banyak siswa yang merasa kesulitan dalam menyelesaikan permasalahan yang diberikan dalam bentuk soal cerita.

Published: November 2022

Progressive increase in exports of Ukrainian agricultural and food position, maintaining the leading position of the state in world commodity markets in the agri-food segment, especially in the grain market should not pose a threat to food security and the emergence of shortages in the domestic market. The article is devoted to the identification of features and indicators of effective realisation of the export potential of the Ukrainian grain market in view of the food security of the state. The methodological basis of the study was a number of general and special research methods, in particular, the dialectical method of cognition, the method of comparisons, empirical, graphical and abstract-logical methods. The result of the study is the identification of trends in foreign economic relations in the field of grain trade. Potential threats to Ukraine’s food security from the increase in the volume of export-import operations in the grain market have been identified. The need for state coordination of processes to eliminate potential threats to the internal market has been highlighted. Theoretical and methodological approaches to the regulation of foreign economic transactions in the grain market based on the definition of tools to correct existing disparities in the realisation of economic interests of producers and traders in the context of food security gained further development. Along with the positive changes in the development of international grain trade, potential threats to the country’s food security and to domestic market operators were identified. Proposals for their elimination by active methods of state regulation were substantiated.

Published: November 2022

BACKGROUND: The use of sensory based interventions (SBI) by many parties including speech-language pathologists (SLPs) are evident despite limited proof of their efficacy. Insight into SLPs’ implementation, knowledge, and perceptions of SBI are crucial to define and guide such practices in the field of speech-language therapy. OBJECTIVES: The study aimed to gather information regarding the nature of SBI, knowledge of sensory processing and SBI, and perception of the role and outcomes of SBI as implemented by SLPs. METHOD: A quantitative survey design was employed. Sixty-five SLPs working in early intervention clinics, public hospital clinics, school settings, and private practice responded to a questionnaire. Results were analysed using SPSS statistical software. RESULTS: Respondents indicated that they often implement SBI using various sensory activities and equipment. They answered more than half of the questions related to the prevalence and nature of sensory difficulties in children with Autistic Spectrum Disorder (CWASD) accurately. Respondents answered fewer questions regarding the differences between SBI and sensory integration therapy accurately. Regular collaboration with and guidance from occupational therapists (OTs) were reported. Respondents acknowledged the role of SLPs in addressing sensory difficulties in CWASD. Positive outcomes for the implementation of SBI in speech-language therapy were stated. CONCLUSION: Despite the limited evidence for the efficacy of SBI, SLPs regularly implement such practices to enhance therapy outcomes. The insights gathered from this study support reports of positive outcomes related to SBI. The need for more rigorous efficacy studies, clearer guidelines and specialised training for SLT’s in SBI are highlighted.

Published: November 2022

The research heat of artificial intelligence is increasing, and intelligent transportation is a direction of artificial intelligence. Short-term traffic flow prediction is the embodiment of use of artificial intelligence. In view of the problem that there is no communication between subgroups and the diversity of groups is limited after the convergence operation of mind evolutionary algorithm, this paper introduces learning mechanism and reflection mechanism to improve the mind evolutionary algorithm (RMEA). Through learning mechanism, each subgroup can obtain the winning individual information of all other subgroups on the premise of maintaining its own characteristics, and generating new individuals. After the learning mechanism, the reflection mechanism is used to select the best individuals, and the RMEA-WNN prediction model is constructed. Moreover, taking the prediction residual of model as the data set, the LSTM model is used to forecast the data of traffic flow residual error, and the RMEA-WNN-LSTM prediction model is constructed. The simulation prediction accuracy of the complex model reaches 96.8%, which proves that the model has practical application value.

Published: November 2022

A modification to the gear tooth surface is crucial for reducing whistling noise generated by gearboxes of electric vehicles. Using the orthogonal test method, this paper studies geometry parameters of gear pair and the effect of load conditions on modification parameters of tooth surface. To achieve this, the paper develops various test models of gear pairs based on MASTA and then corrects the gear profiles according to load distribution state. The influential factors of gear transmission to modification parameters of tooth surface are thereby intuitively analyzed. Finally, a prediction model of the result of gear modification is built, based on test parameters, by method of support regression vector machine, providing a valuable reference to determine the tooth-surface modification parameters of the transmission gear of electric vehicles.

Authors: Xiong Jianxin , Yin Hui , Pan Meisen
Published: November 2022

In addition to a more extreme network experience and larger network capacity, 5G can also be used to rapidly transmit massive global text data at higher transmission speeds and higher reliability than previous communication technologies, allowing more communication devices around the world to operate at a faster rate. The transmission speed is safe and reliable to connect with each other. The rapid development of image recognition technology will be more effective in improving the operational efficiency of various industries. At present, scholars have used 5G technology and image recognition technology in the field of book management. This paper designs a book image recognition recommendation scheme based on 5G technology, in order to improve the problems of inaccurate book sales targets and low book classification efficiency of merchants from various perspectives. The image recognition book recommendation system combined with 5G technology is mainly divided into two steps: image recognition and book recommendation. The ultra-high speed provided by 5G technology can greatly improve the speed and accuracy of image recognition. Significantly reduces program running time. This paper first analyzes the related concepts of 5G, image recognition and recommendation algorithm, then sorts out the book image recognition method, and then designs the book recommendation purchase method. Combined with 5G technology, the image recognition and recommended purchase strategy are optimized. Finally, an online questionnaire is used to investigate the merchants using this method. The survey results show that the merchants who use this identification and purchase recommendation method have better performance in book classification, book personality recommendation, customer loyalty and book sales rate have greatly improved.
A novel SSA-CatBoost machine learning model for credit rating
Authors: Yang Ruicheng , Wang Pucong , Qi Ji
Published: November 2022

Categorical Boost (CatBoost) is a new approach in credit rating. In the process of classification and prediction using CatBoost, parameter tuning and feature selection are two crucial parts, which affect the classification accuracy of CatBoost significantly. This paper proposes a novel SSA-CatBoost model, which mixes Sparrow Search Algorithm (SSA) and CatBoost to improve classification and prediction accuracy for credit rating. In terms of parameter tuning, the SSA-CatBoost optimization obtains the most optimal parameters by iterating and updating the sparrow’s position, and utilize the optimal parameter to improve the accuracy of classification and prediction. In terms of feature selection, a novel wrapping method called Recursive Feature Elimination algorithm is adopted to reduce the adverse impact of noise data on the results, and further improves calculation efficiency. To evaluate the performance of the proposed SSA-CatBoost model, P2P lending datasets are employed to assess the prediction results, then the interpretable Shap package is used to explain the reason why the proposed model considers a sample as good or bad. Consequently, the experimental results show that the SSA-CatBoost model has an ideal accuracy in classification and prediction for credit rating by comparing the SSA-CatBoost model with the CatBoost model and other well-known machine learning models.

Background: In Parkinson’s disease (PD), excessive iron deposition in the substantia nigra may exacerbate α-synuclein aggregation, facilitating the degeneration of dopaminergic neurons and their neural projection. Objective: To investigate the interaction effect between nigral iron deposition and PD status on brain networks. Methods: Eighty-five PD patients and 140 normal controls (NC) were included. Network function and nigral iron were measured using multi-modality magnetic resonance imaging. According to the median of nigral magnetic susceptibility of NC (0.095 ppm), PD and NC were respectively divided into high and low nigral iron group. The main and interaction effects were investigated by mixed effect analysis. Results: The main effect of disease was observed in basal ganglia network (BGN) and visual network (VN). The interaction effect between nigral iron and PD status was observed in left inferior frontal gyrus and left insular lobe in BGN, as well as right middle occipital gyrus, right superior temporal gyrus, and bilateral cuneus in VN. Furthermore, multiple mediation analysis revealed that the functional connectivity of interaction effect clusters in BGN and medial VN partially mediated the relationship between nigral iron and Unified Parkinson’s Disease Rating Scale II score. Conclusion: Our study demonstrates an interaction of nigral iron deposition and PD status on brain networks, that is, nigral iron deposition is associated with the change of brain network configuration exclusively when in PD. We identified a potential causal mediation pathway for iron to affect disease severity that was mediated by both BGN dysfunction and VN hyperfunction in PD.

Authors: Cogan Betsy , Pearson Regis C. , Paton Chad M. , Jenkins Nathan T. , Cooper Jamie A.
Published: November 2022

BACKGROUND:

Pecans are rich in nutrients known to benefit cognition.

OBJECTIVE:

To examine the effect of daily pecan consumption on cognitive function in older adults.

METHODS:

In this randomized controlled trial, 42 adults (50–75y) either consumed 68 g of pecans/day for 4-weeks (pecan; n = 21) or avoided all nuts (control; n = 21). At pre- (V1) and post-intervention (V2) visits, cognitive function was assessed using a fluid composite score and four subtests from the NIH Toolbox-Cognitive Battery (NIHTB-CB) (Flanker Test, Digital Change Card Sort Test (DCCS), Picture Sequence Memory Test (PSMT), NIHTB Auditory Verbal Learning Test (RAVLT)) at fasting, 30- and 210-min after a high-saturated fat meal void of pecans.

RESULTS:

From V1 to V2, fasting and postprandial cognitive performance did not differ between groups. There were improvements in both groups for fasting fluid composite score ( p < 0.001) and performance on RAVLT, PSMT, DCCS, and Flanker tests from V1 to V2 ( p < 0.001 for all), with no differences between groups. Additionally, postprandial performance on RAVLT, PSMT, and Flanker tests improved at V2 ( p < 0.01 for each), with no differences between groups.

CONCLUSIONS:

A short-term pecan-enriched diet did not provide additional cognitive benefits in healthy older adults in the fasted or postprandial state.

Strategi yang digunakan para pelaku usaha Ayam Panggang Gandu dalam membangun persepsi konsumen dilakukan dengan cara membentuk persepsi kualitas positif melalui atribut produk ayam panggang, khususnya dari sisi kualitas, fitur, harga, dan pelayanan prima. Keungggulan produk dan layanan yang dihadirkan telah membuat konsumen puas dan akhirnya menceritakan pengalamannya kepada orang lain. Terjadinya komunikasi lisan, tertulis, dan elektronik melalui WOM (word of mouth) dan E-WOM (electronic word-of-mouth) antar masyarakat mendorong terbentuknya brand identity dan menimbulkan brand image, persepsi positif di benak konsumen terkait Ayam Panggang Gandu. Disadari atau tidak, konsumen yang puas dengan kualitas produk dan layanan telah melakukan promosi, merekomendasikan kepada orang lain di sekitarnya. Informasi keunggulan yang tersebar melalui E-WOM yang diperoleh dari orang lain memiliki pengaruh kuat. Rekomendasi dari konsumen lain lebih dapat dipercaya, karena bersifat mandiri, non komersial, jujur, dan tidak ada hubungan dengan para pelaku usaha. Disamping itu daya jangkau penyebarannya pun sangat luas, karena berlangsung di situs jejaring sosial (social networking sites) internet dan media sosial yang tidak ada batasan geografis, waktu maupun ikatan sosial, sehingga sebelum memutuskan untuk membeli suatu produk, konsumen dapat memperoleh banyak kesempatan untuk bertukar informasi dengan mudah dan efektif. Pemanfaatan E-WOM dapat meningkatkan penjualan secara signifikan dalam waktu relatif cepat.

Tender dapat artikan lelang atau sistem jual beli yang dilakukan suatu pihak dengan cara mengundang vendor (penjual atau penyedia) untuk mempresentasikan harga dan kualitas yang dibutuhkan. Harga dan kualitas yang terbaiklah, nantinya yang akan menjadi pemenang. Lelang atau sistem tender sangat digemari terutama oleh perusahaan-perusahaan, mengingat jumlah nominal dan durasi kontrak dalam suatu lelang sangat besar dan bervariasi. Penelitian ini bertujuan untuk mengetahui prosedur tender pengadaan kereta api oleh PT KAI (Persero) dari PT INKA (Persero) khususnya untuk tender umum pascakualifikasi, serta dokumen yang diperlukan dalam proses tersebut. Penelitian ini menggunakan metode deskriptif kualitatif yang bersumber dari data primer yaitu dengan melakukan wawancara, observasi, dan dokumentasi objek penelitian serta data sekunder yaitu dengan melakukan pengkajian bahan pustaka yang relevan.

Does NHIS Enrollment Increase Maternal Healthcare Utilization? Evidence from the Ghana Demographic and Health Survey (GDHS)
Authors:   Korea Association of International Development and Cooperation, Lee Sangmi , Cho Yoon Young
Published: November 2022

Purpose: This research aims to examine the effects of Ghana’s National Health Insurance Scheme (NHIS) on maternal healthcare utilization.
Originality: The most of the previous studies examined the association between health insurance enrollment and the use of maternal healthcare service. However, our paper investigated the causal relationship of the NHIS enrollment and maternal healthcare utilization based on the latest available dataset of 2014 Ghana Demographic and Health Survey (GDHS), using the Propensity Score Matching (PSM). Another difference between our analysis and previous papers is that control variables were selected from a theory-based framework.
Methodology: To address selection bias and move towards more causal estimates, PSM was conducted for analysis.
Result: The NHIS increased 9.5% points of access to at least four antenatal care visits. It also led to the positive effects on facility-based delivery after at least four antenatal care visits, which increased by 11% points. Lastly, women enrolled in the NHIS were significantly 13.4% points more likely to have the first prenatal check in a trimester.
Conclusions and Implication: Our results imply that broadening access to the NHIS offering coverage of maternal healthcare is needed to encourage women to use maternal healthcare, at the level of minimum recommended standards. On the other hand, since the endogeneity problem is still an issue despite using PSM, the overestimation of the results in our study needs to be considered.
