Whereas, the significances of the factors chosen in the machine learning based prediction are crucial. This article focuses on selecting the significant factors predicting the stock price and volatility from based on the Long short-term memory and Random Forest model. First of all, four years of the data of some technology giants’ stock, industry indexes, market indexes and settle price of the future are taken into consideration and prepared in advance. By creating the time series data and adding the data sets of some other possible factors, the research combines the vertical and horizontal analysis to calculate the importance of the features to forecast either return or volatility. The main factors analysis is used to select the feature, tune the day of time series and improve the model. Last but not least, the Principal Component Analysis and Grey Model are regarded as the farther research field. According to the results, 5 days of time series performs best in both predicting the return and volatility. Apart from that, the index value of Standard and Poor 500 Index Technology Plate and the average of the return are most significant for return prediction, when the standard deviation of Amazon, Microsoft, SPLRCT and USTEC are most important features for volatility. The future research direction lies in the theoretical proof of the effectiveness of the combination of the horizontal and vertical analysis and more empirical research will be done to enhance the confidence of the result. These results shed light on the most significant factors of the return and standard deviation and obviously hence the accuracy of the prediction.","PeriodicalId":37324,"journal":{"name":"International Journal on E-Learning: Corporate, Government, Healthcare, and Higher Education","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72902431","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pre-service teacher preparation was one of the keys to cultivate the interest in STEM for future generation. With this, the current study determined Early Childhood Education (ECE) pre-service teachers’ aspects regarding STEM such as their belief, understanding, self-efficacy, and intention. Also, the association or correlation of STEM aspects were measured. As a result of multiple analyses, it was found out that they had very high STEM aspects and there was a positive association or correlation of the aspects. New conceptions of STEM were also constructed by almost half of the pre-service teachers. There was no significant gender difference found in their aspects regarding STEM. This finding implied that the ECE pre-service teachers who were mostly female had no gender bias in regards to possible integration of STEM in their own future classroom.","PeriodicalId":37324,"journal":{"name":"International Journal on E-Learning: Corporate, Government, Healthcare, and Higher Education","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76894596","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The construction of ILSTC provides a more well-functioning infrastructure and optimized business climate for trade interconnection between China and the ASEAN countries, which drives cross-border e-commerce (CBEC) to develop rapidly. The development of CBEC relies on the support of cross-border e-commerce logistics (CBECL), and the two are mutually reinforcing. At present, the incongruous growth of China-ASEAN CBEC and CBECL is the main factor restricting the cross-border business between the two economies. The main problems are shown in the great divide in infrastructure construction, lack of logistics standards unification, high logistics costs, and low timeliness. This paper analyzes the development of China-ASEAN CBEC and logistics in the background of ILSTC construction, combined with the e-commerce connectivity index (ECI) and logistics performance index (LPI).

The Markowitz model considers expected return and risk, while not attaching enough importance to risk-free assets. The Index model is brief, but the assumption it uses does not have a major influence on the results obtained. Comparing the results, it is obvious that the return and standard deviation of Index model portfolios are higher than the Markowitz model's one.

One of the recommendations of DepEd is the use of evidence-based instructional practices (EBIPs). However, little is known regarding the factors that influence Filipino mathematics teachers’ implementation of a certain teaching strategy. The main objective of this current study is to find out whether mathematics teachers’ knowledge and attitudes predict their practice of EBIPs. This descriptive study involved 114 teacher-respondents from one district in Laguna. Data were gathered using a researchers-made questionnaire distributed online using Google forms. Findings revealed that 47.5% of mathematics teachers, in general, are knowledgeable of EBIPs while 36.57% of the respondents have misconceptions about EBIPs. In addition, it was found that, generally, they have a positive attitude towards EBIPs (M = 3.63, SD = 0.51). The result also showed that the respondents employ EBIPs in their classrooms to a moderate extent (M = 3.19, SD = 0.46). Teacher-respondents reported that they are satisfied with the implementation of a teaching strategy when a strategy is beneficial for the learners’ holistic development and helps improve the pedagogical process. Stepwise multiple regression analysis revealed that mathematics teachers’ attitude towards EBIPs and misconception of EBIPs predict their use of the evidence-based practice. Findings indicate the there is a need to correct these misconceptions through proper information dissemination of EBIPs.","PeriodicalId":37324,"journal":{"name":"International Journal on E-Learning: Corporate, Government, Healthcare, and Higher Education","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85487129","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two experimental cases are established and examined with historical data from 2000 to 2020: first, as the benchmark, only lagged daily cash price fluctuations are used as input to project price evolution five steps forward; in the second case with the same objective, the study considers both spot prices and the time series of factors obtained through futures curve decomposition by Principal Component Analysis (PCA). In each case, the study implements both an autoregressive time series analysis and a Long Short-Term Memory model (LSTM) to generate the predictions of interest. Simplified grid searches are performed based on validation loss to determine the latter's optimal design and hyperparameter values. With Root Mean Square Error (RMSE) and Coefficient of Determination () as performance evaluation measures, out-of-sample tests lead to a decently encouraging result for the significance of futures market properties as predictors of the spot. That is, potentially, prices of futures contracts aggregate new information that facilitates cash price forecasting. Besides, despite the fact that their accuracy for 1-Day Ahead prediction fails to surpass linear, econometric models, LSTM models demonstrate overall better predicting capability, highlighting implicit nonlinear dependencies within the dataset, and hence serve as reliable approaches to energy forecasting.","PeriodicalId":37324,"journal":{"name":"International Journal on E-Learning: Corporate, Government, Healthcare, and Higher Education","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86203752","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data of six portfolios from the year 1963 to 2019 at the start of each month are selected to deduce their relationship with six factors through multiple linear regression. Variance inflation factor and correlation coefficient are both calculated to exclude the multicollinearity among the regressors. R-squared about six portfolios are all above 0.9, meaning that six portfolios fit the six-factor model well. The results indicate that the factor MKT is positively significant to all six portfolios, and the coefficient of MKT is the highest among all the factors, very close to 1 or even above, which suggests MKT has the biggest impact on six portfolios and the six portfolios fit the market trend well. The outcome also illustrates that factor MOM is of less significance to the six portfolios. However, MOM is negatively significant to portfolios 1,2,5, and 6, thus should not be ignored.","PeriodicalId":37324,"journal":{"name":"International Journal on E-Learning: Corporate, Government, Healthcare, and Higher Education","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75837354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
