The purpose of this research is to analyze the formation of the optimal portfolio on the Jakarta Islamic Index 30 (JII30) stocks during the new normal period. The model used is a single index model. This study uses secondary data for the period December 2020 - November 2021 from stocks listed on JII30 on the Indonesia Stock Exchange. The results showed that the selected model provides optimal benefits. The risk-free asset return does not provide a higher return than the simulation results. Of the 30 stocks listed in JII30, obtained 7 stocks with the most significant proportion of funds, namely ERAA (25.72%), MDKA (24.87%), TLKM (17.98%), EXCL (12.82%), AKRA (7.54%), ADRO (6.73 %) and ANTM (4.34%). The formation of the optimal portfolio in this study produces an expected return of 0.009974 or 1%, where the portfolio return is above the market rate of return and the average risk-free rate. Meanwhile, the optimal portfolio risk obtained is 0.003173 and the standard deviation is 0.056327 or 5.63%. The impact of the Covid-19 pandemic which has subsided and the economy is getting better has resulted in the formation of an optimal JII30 portfolio that can be carried out and reduce investment risk during the new normal period.Â Keywords: Jakarta Islamic Index 30 (JII30), Single Index model, new normal, Optimal portfolio

PROFESSIONAL ACADEMIC MUSIC EDUCATION AND MODERN SOCIOCULTURAL ENVIRONMENT: ASPECT OF VALUE AND WORLDVIEW
Authors: Dolhikh Yaroslav 
Published: August 2022

A set of values and worldviews of professional academic music education in the context of the current sociocultural situation is considered. The complex of views on music is interpreted as a way of musical socialization. The coexistence of a wide range of musical socialization channels in the modern world is positioned as a prerequisite for the intonational images of the world confrontation. It is determined that academic music education transmits the mental attitudes of opus music, according to which it occupies a dominant position in the tone atmosphere. The hierarchy of musical practices as a result of non-academic music evaluation according to the academic sphere parameters is explored. The position of this value and worldview system through the prism of musical-cultural polycentrism is analyzed. Mandatory markers of academic music leadership have been shown to be conditional. It is stated that the writing nature of making music should not be positioned as a criterion for determining the professionalism and value of non-academic music practices. It is emphasized that the protection of this parameter affects the shift of emphasis from the “music as process” to “music as objects”. The primacy of the concert performance communicative model is denied. It is stated that this deprives all its subjects of active participation. It is noted that the parameter of autonomy of musical creativity should not be used in positioning different music practices. The functional distinctiveness of musicians is demonstrated on the two segments of the music services market. The meaning of the categories “elitism” and “art” is refuted on the basis of sociological and cultural transformations. It is indicated that on their basis have been developed new limits of the definition of these concepts.
Keywords: professional academic music education; training of musical art specialists; value and worldview complex of academic music; ideology of opus music; modern socio-cultural environment; subcultural stratification; chaotic intonational versatility; sociology of music education.

Authors: Collins Helen , Callaghan David 
Published: August 2022

International students contribute to the academic and cultural life of universities yet often face discrimination and isolation. Studies highlight that support from the host students can make the difference between an easy or difficult transition. This article is part of a larger project about host student perceptions of international students. Initial analysis indicated that social interactions among international and host students do not become intertwined informally and work best through planned interventions. During the pandemic institutions transitioned from face-to-face to online learning using zoom. We noticed a marked increase in interaction among students online and returned to our research participants to enquire what differences online learning had made to their intercultural experiences. This study focuses on the impact of Virtual Classrooms (VCs) on intercultural relationships, and shows that Zoom offers a platform for increased interaction than face-to-face classrooms.

Authors: Korwin-Mikke Katarzyna 
Published: August 2022

Celem niniejszego artykułu jest zbadanie obrazu przedstawicieli Globalnego Po[1]łudnia wyłaniającego się z polskiej wielokulturowej literatury dziecięcej XXI wie[1]ku oraz sprawdzenie, czy są w niej powielane mity i wzorce narracji zaczerpnię[1]te z dyskursu kolonialnego. Autorka tekstu poddaje analizie utwory należące do dwóch kategorii literatury wielokulturowej według klasyfikacji Mingshuiego Caia i Rudine Sims Bishop: literatury światowej oraz literatury międzykulturowej. Taki dobór literatury podmiotu pozwala na sprawdzenie, jakie konteksty sytuacyjne najbardziej sprzyjają ujawnianiu się w narracji kolonialnego sposobu myślenia. Zostaje również podjęta próba powiązania wizerunków przedstawianych w oma[1]wianych dziełach literackich z wyzwaniami współczesnego świata: edukacją glo[1]balną, etyczną turystyką i pomocą charytatywną czy też zjawiskiem migracji oraz uchodźstwa
Effects of ulcerative colitis and Crohn’s disease on neurodegenerative diseases: A Mendelian randomization study
Authors: Li Hong , Wen Zheng 
Published: August 2022

Background: Both ulcerative colitis (UC) and Crohn’s disease (CD) are associated with neurodegenerative diseases (NDs) in observational studies, but the causality remains controversial. We aimed to use Mendelian randomization (MR) analysis to explore causal associations between UC and CD and NDs.Methods: We used single nucleotide polymorphisms (SNPs) associated (p &lt; 5 × 10−8) with UC and CD as instrumental variables (IVs) to perform the MR analysis on the risks of three NDs, namely, Alzheimer’s Disease (AD), Parkinson’s Disease (PD), and Amyotrophic Lateral Sclerosis (ALS). The inverse variance weighted (IVW) was the primary method and supplement with the weighted median and MR-Egger regression. Moreover, the MR-Egger intercept test, Cochran’s Q test, and “leave one out” sensitivity analysis were implemented to assess the horizontal pleiotropy, heterogeneities, and stability of these SNPs on NDs. To verify the stability of the results, we re-run the MR analysis by using another set of IVs of UC and CD. A reverse causality analysis was conducted to test whether NDs were causally associated with UC or CD. The significance threshold was set at p &lt; 0.05/6 = 0.008.Results: In the primary MR analysis, the IVW method yielded no evidence to support a causal association between UC and PD (OR: 1.01, 95% CI: 0.96–1.06, p = 0.65), AD (OR: 1.00, 95% CI: 0.99–1.00, p = 0.57), or ALS (OR: 0.98, 95% CI: 0.96–1.01, p = 0.24), and neither did the MR-Egger and weighted median methods. Our MR analysis also suggested no definitively causal effect of the genetically predicted CD on PD (OR: 1.01, 95% CI: 0.97–1.05, p = 0.54), AD (OR: 1.00, 95% CI: 0.99–1.00, p = 0.26), or ALS (OR: 0.99, 95% CI: 0.96–1.02, p = 0.41), as well as MR-Egger and weighted median methods. Consistent results were found in validation analyses. We did not find a significant causal effect of NDs on UC or CD in the reverse MR analysis.Conclusion: No evidence indicated an association between the risks of NDs and genetically predicted UC or CD. The MR results did not support a causal association between UC or CD and three NDs.
Using expression quantitative trait loci data and graph-embedded neural networks to uncover genotype–phenotype interactions

Published: August 2022

Motivation: A central goal of current biology is to establish a complete functional link between the genotype and phenotype, known as the so-called genotype–phenotype map. With the continuous development of high-throughput technology and the decline in sequencing costs, multi-omics analysis has become more widely employed. While this gives us new opportunities to uncover the correlation mechanisms between single-nucleotide polymorphism (SNP), genes, and phenotypes, multi-omics still faces certain challenges, specifically: 1) When the sample size is large enough, the number of omics types is often not large enough to meet the requirements of multi-omics analysis; 2) each omics’ internal correlations are often unclear, such as the correlation between genes in genomics; 3) when analyzing a large number of traits (p), the sample size (n) is often smaller than p, n &lt;&lt; p, hindering the application of machine learning methods in the classification of disease outcomes.Results: To solve these issues with multi-omics and build a robust classification model, we propose a graph-embedded deep neural network (G-EDNN) based on expression quantitative trait loci (eQTL) data, which achieves sparse connectivity between network layers to prevent overfitting. The correlation within each omics is also considered such that the model more closely resembles biological reality. To verify the capabilities of this method, we conducted experimental analysis using the GSE28127 and GSE95496 data sets from the Gene Expression Omnibus (GEO) database, tested various neural network architectures, and used prior data for feature selection and graph embedding. Results show that the proposed method could achieve a high classification accuracy and easy-to-interpret feature selection. This method represents an extended application of genotype–phenotype association analysis in deep learning networks.

Published: August 2022

BackgroundThe International Association for the Study of Lung Cancer (IASLC) proposed a novel grading system for invasive lung adenocarcinoma, but lymphatic invasion was not evaluated. Meanwhile, the scope of lymph node dissection in part-solid invasive lung adenocarcinoma (PSILA) is still controversial. Therefore, this study aims to explore preoperative risk factors for lymph node metastasis in PSILA, to provide reference for intraoperative dissection of lymph nodes.MethodsFrom 2018 to 2020, clinical data of patients (stage cN0) consecutively diagnosed as PSILA were retrospectively analyzed and classified according to the novel grading system. Logistic regression was conducted to screen the clinicopathological factors of lymph node metastasis in PSILA.ResultsA large cohort of 960 patients with PSILA who underwent lobectomy or sub-lobectomy were enrolled. By logistic regression analyses, solid part size, bronchial cutoff sign, spiculation, and carbohydrate antigen 199 (CA199) were eventually identified as independent risk factors for lymph node metastasis, based on which a nomogram was built to preoperatively predict the risk of lymph node metastasis [area under the receiver operating characteristic curve (AUC)=0.858; concordance index = 0.857; best cutoff, 0.027]. This suggests that intraoperative systematic lymph node dissection is recommended when the predicted risk value exceeds 0.027. Reproducibility of the novel grading system was verified.ConclusionsThe novel IASLC grading system was applicative in real world. The nomogram for preoperative prediction of lymph node metastasis may provide reference for the lymph node dissection strategy during PSILA surgeries.

Published: August 2022

BackgroundFoot and mouth disease (FMD) is a highly contagious viral disease of cloven-hoofed animals, which hampers livestock production and productivity in Ethiopia. This cross-sectional study was conducted from January to December 2021 to estimate the seroprevalence of FMD in cattle and to assess farmers' knowledge about the disease in selected districts of the Gamo zone. Three districts and two kebeles (smallest administrative division) from each district were purposively sampled using a simple random sampling technique to select individual animals from each kebeles. A total of 384 sera samples were collected, and concurrently, 100 farmers were interviewed. The samples were tested for antibodies against nonstructural proteins of the FMD virus using a 3ABC enzyme-linked immunosorbent assay (ELISA). Univariable and multivariable logistic regressions were used to analyze FMD-associated risk factors.ResultThe questionnaire survey result revealed that among the interviewed farmers, 66% of farmers had knowledge about the disease, and 28% of farmers reported having a case of FMD in at least one cattle in their farm in the previous 6 months. The overall seroprevalence of FMD in cattle was 26.8%. The multivariable logistic regression revealed that age, breed, and agroecology had a significant association with seropositivity. Higher seroprevalence (64.57%) was observed in lowland, followed by midland (9.30%) and highland (5.88%). Study animals from lowland areas were 9.26 times more likely to be seropositive (OR = 9.26, CI = 2.22–38.62) for FMD than highland animals. Also, adult animals were 9.01 times (OR = 9.01, CI = 3.18–25.53) more likely to be seropositive for the disease than young animals. The multivariable logistic regression revealed that crossbreeds have an 84.7% (OR = 0.153, CI = 0.028–0.82) lower likelihood to be seropositive to FMD than local breeds.ConclusionThis study result confirms that FMD is highly prevalent in the study area, and farmers' knowledge regarding disease transmission and vaccine availability is minimal. Hence the regional concerned bodies should implement FMD vaccination campaigns and create awareness for smallholder farmers regarding the disease transmission, FMD vaccine schedule, and vaccination importance.
