This paper makes a detailed analysis of the integrated mining algorithm, analyzes the characteristics of curriculum big data, and analyzes the existing problems of the current association rule mining algorithm, as well as the defects and deficiencies when applied to the curriculum data. Aiming at the problem of mining the entire data set by the mining algorithm, this topic proposes the idea of using the K-means algorithm for clustering processing and uses the Ball-tree structure on the basis of the original K-means algorithm to improve the efficiency of the algorithm. The data set is separated into several clusters of an appropriate number. In the flipped classroom, the basic knowledge is put before the class for learning, and the further deepening and practical application of language knowledge is completed in the class. Teachers can give timely guidance when encountering unsolvable difficulties so that students’ learning can be more effective. This new teaching model not only strengthens students’ confidence in learning and increases their interest in learning, but also increases the opportunities for students to interact with teachers and classmates in the classroom, allowing them to construct the meaning of knowledge in the fun of interactive communication. The classroom has become relaxed, lively, and attractive, and students’ sense of autonomy, self-learning ability, and collaborative inquiry ability have also been unknowingly improved. Among the main factors, the willingness to flip, emotional state, leadership role, and online learning input have a significant positive impact on collaborative learning performance, and the sense of competition has a partial negative impact on collaborative learning performance, of which positively affecting individual knowledge mastery. Among the nonmain factors, the degree of difficulty of the course, teacher-student interaction, teacher motivation, and evaluation mechanism have a significant positive impact on collaborative learning performance. Classroom assistive technology has a partial negative impact on collaborative learning performance. From the perspective of group performance, group-level performance considerations such as the quality of group conversations and the degree of group knowledge sharing in collaborative learning performance are more affected by nonsubject factors.

Abstract. The challenges China faces in terms of water availability in the agricultural sector are exacerbated by the sector's low irrigation efficiency. To increase irrigation efficiency, promoting modern irrigation technology has been emphasized by policy makers in the country. The overall goal of this paper is to understand the effect of governmental support and economic incentives on the adoption of modern irrigation technology in China, with a focus on household-based irrigation technology and community-based irrigation technology. Based on a unique data set collected at household and village levels from seven provinces, the results indicated that household-based irrigation technology has become noticeable in almost every Chinese village. In contrast, only about half of Chinese villages have adopted community-based irrigation technology. Despite the relatively high adoption level of household-based irrigation technology at the village level, its actual adoption in crop sown areas was not high, even lower for community-based irrigation technology. The econometric analysis results revealed that governmental support instruments like subsidies and extension services policies have played an important role in promoting the adoption of modern irrigation technology. Strikingly, the present irrigation pricing policy has played a significant but contradictory role in promoting the adoption of different types of modern irrigation technology. Irrigation pricing showed a positive impact on household-based irrigation technology, and a negative impact on community-based irrigation technology, possibly related to the substitution effect that is, the higher rate of adoption of household-based irrigation technology leads to lower incentives for investment in community-based irrigation technology. The paper finally concludes and discusses some policy implications.

The purpose of the current study was to investigate the relationship between financial structure towards the financial performance of companies listed on Amman stock exchange (ASE) as one of the emerging economies. This paper adopted a panel data set of 88 non-financial companies listed on the ASE over a period of 10 years from 2009 to 2018. According to empirical results that there is significant evidence to support the fact that debt repaying ability (DRAB), managerial ownership (MANOW), and foreign ownership (FOROW) are positively related to firm performance. Otherwise, the findings revealed no evidence to support the impact of the financial structure ability (FSA) towards firm performance. Moreover, the findings support the fact that firm size (SIZ) has a positive impact on firm performance of companies listed on the ASE. On the other hand, (AGE) has a negative impact on firm performance, while (GROWTH) has no impact on firm performance. The current study encourages managers to maintain a good percentage of debt repaying ability and owners to grant shares as managers’ incentives, and also to attract foreign investors. Future studies, should try applying the current study on the financial sector.

This paper attempts to examine Pakistan’s trade patterns with South Asian countries by using a gravity model of trade. The main objective of the study is to quantify the long‑run impacts of gravity variables. To achieve this objective, a panel data set for the period 2003 to 2017 has been used. Based on the mixed evidence of the results of panel unit root tests, Pooled Mean Group (PMG) and Panel Dynamic Ordinary Least Square (DOLS) techniques are applied. The outcome of the PMG and Panel DOLS models justifies the theoretical background of the gravity model and suggests that all the basic gravity variables haveusual signs. The RGDPs and population of both Pakistan and the partner country have a positive impact on their bilateral trade. On the other hand, the distance between the two trading countries and the exchange rate have a negative impact on bilateral trade.The uniqueness of this study is that it measures the impacts of qualitative variables along with basic gravity variables. Language similarities and common borders have a positive impact on bilateral trade. Pakistan has borders with India and Afghanistan, but their trade relations are not worth mentioning. The military conflicts between Pakistan and India, and the political suspicions between Pakistan and Afghanistan hinder their trade relations.

Nowadays, small- and medium-sized enterprises play crucial roles in both developed and developing countries. They create new employment, fulfill the market gap, contribute to Gross Domestic Product and boost the whole economy. However, small- and medium-sized enterprises face more financial constraints than large enterprises, which prevent them from growing and expanding their activities. This paper aims to investigate how the innovation of small- and medium-sized enterprises impacts on credit accessibility in Vietnam from 2005 to 2015, through five aspects of innovation: new products, new technology, improved existing products, research and development investment, and machine innovation. The data set consists of more than 4500 observations of small- and medium-sized enterprises in Vietnam. This data set is taken from a survey conducted within the framework of cooperation among UNU-WIDER, the University of Copenhagen and Vietnamese government agencies. Using panel regression model, we found out that three out of five innovation factors significantly impact on credit accessibility. More specifically, research and development investment and new product have negative impact on credit accessibility; whereas new technology has positive impact on credit accessibility. These findings are useful for firm managers, banks and policy makers to help small- and medium-sized enterprises overcome financial constraints through innovation aspects.

The basic purpose of this study was to look at the position of Better Management Practices (BMPs) of cotton crop in order to reduce the burden on our natural scarce resources. Relevant information was taken from 150 respondents from the district Khanewal, Punjab. The results of this study revealed that the education level and landholding size of respondents have a positive impact on the adoption of sustainable agricultural practices. While the farmer’s age and farming experience were found a negative impact on BMPs adoption rate. Similarly, contact of respondents with the staff of farmer’s field schools and the number of visits of farmer’s field school staff were found positively correlated to BMPs adoption rate. The results of the regression analysis revealed the impact of different agriculture inputs and BMPs on cotton yield. The results showed that the age of the farmers, education, fertilizer, irrigations, water scouting, cotton area, farmyard manure, and hybrid seed variety and sowing method had a positive sign while the sign of pesticide coefficient was negative. The gross margins of BMPs adopter and non-adopter were 45,955 PKR and 28,790 PKR per acre respectively. The model also indicated that the production function fits well with the given data set. Therefore, the results of this study conveyed policy messages for the private and public organizations to promote BMPs for the betterment of the farming community.

With the advancement of big data and neural network technology, flipped classroom informatization has shifted the traditional order of knowledge transfer and internalization, emphasizing students’ autonomous learning before class, knowledge absorption, and knowledge completion in class with the assistance of teachers. Students’ internalization and consolidation create the conditions for individualized learning. In foreign teaching, the benefits and feasibility of the flipped classroom have been demonstrated, and it is a promising new teaching model. Although recent research on oral English teaching in Chinese universities has yielded promising results, students’ classroom activity and participation remain low, learning initiative is lacking, and opportunities and time for oral training are insufficient. This article uses flipped classroom, big data, and neural network technology to teach college oral English classes, with the goal of determining whether the flipped classroom model can help students improve their oral English proficiency and self-learning ability, as well as exploring students’ attitudes toward the flipped classroom model. This paper first proposes a big data and deep neural network-based algorithm for detecting oral English pronunciation errors, which can be used for self-correction of students in the flipped classroom mode to improve the quality of oral English teaching. Finally, we also conducted simulation experiments, and the experimental results show that our algorithm is 4.12% better than SVM.

This study explored students' perceptions of a flipped classroom for an introductory programming class. Students were required to watch video lectures and read lecture notes in advance (pre-class self-study) to prepare themselves for the in-class lectures and tutorials. A mix-methods approach was employed: quantitative survey (n=204) and qualitative interview (n=7) were administered simultaneously. The results suggested that students are not fully ready for a flipped classroom. Most of the students still prefer face-to-face in-class lectures and tutorials. The in-class activities have a positive impact on students' test performance, especially the male students. Peer learning however induces a negative impact on students' test performance, especially among the female students. Pre-class self-study has no impact on students' test performance, except for those without prior programming experience. Females outperform males even though they lack prior programming experience. Students, regardless of programming background, respond equally to a flipped classroom approach.

BACKGROUND Online health communities (OHCs) have gradually become an important service platform for patients to communicate with physicians and obtain treatment and related medical information. With the rise of OHCs, an increasing number of scholars have begun to study the incentive mechanism of a physician’s online contribution behavior. However, previous studies have ignored the limited effect of online reputation on a physician’s online contribution and the moderating effect of offline reputation. OBJECTIVE We hypothesized that online reputation shows an inverted U-shaped relation with a physician’s contribution and that offline reputation reduces the inverted U-shaped relation, thus weakening the positive impact of reputation on performance and strengthening the negative impact of reputation performance. METHODS Based on incentive theory and prior studies, we proposed three hypotheses. We collected the panel data of 6,648 physicians from Good Physician, one of the largest OHCs in China. An empirical model was built to test our hypotheses. Additionally, the variables representing online reputation were replaced and the data set was split for the robustness check. RESULTS First, our results support the hypothesis of an inverted U-shaped relationship between a physician’s online reputation and their online contribution behavior(β=-0.127, t=13.624, P<.001). Second, we identify the bipolar impact of online and offline reputation on a physician’s online contribution. Specifically, over a period of time, online reputation will promote the contribution of physicians(slope=1.514, P<.001), while offline reputation will inhibit the contribution. Third, our research shows that offline reputation can weaken the impact of online reputation on a physician’s online contribution. CONCLUSIONS We amended the bias of the positive linear correlation between online reputations and online contributions in OHCs. Moreover, by identifying the moderating effect of offline reputation, we ameliorated the interpreting mechanism of online reputation on a physician’s online contribution. The findings improve our understanding of physicians' online contribution behaviors and contribute to the literature on OHCs. Our research can provide guidance for an OHC to design effective personalized incentive mechanisms and encourage physicians to provide more high-quality services.

The objective of this study was to compute economic values of traits using an empirical approach. The data set consisted of 193 257 lifetime records of Holstein and Ayrshire cows. Different profitability measurements were used as the dependent variables in covariance models to compute different sets of economic values. A kilogram genetic increase in fat production had economic values between $25 and $31 in Holstein herds and between $34 and $36 in Ayrshire herds using lifetime profit as the dependent variable. A unit genetic increase in conformation had the highest positive impact on profit ($176 in Holstein herds and $300 in Ayrshire herds) while a similar increase in capacity had a negative impact on profit (between $–30 and $–102 in Holstein herds and $–92 in Ayrshire herds). Using lifetime profit adjusted for the opportunity cost of postponed replacement reduced the influence of type traits on profit. Finally, profits of first lactations were used to study the consequences of changes in pricing systems that occurred in Quebec in August 1992. A kilogram genetic increase in protein production had negative economic values in the 1980s ($–3.70$ in Holstein herds and $–8.33 in Ayrshire herds) and positive economic values after August 1992 ($7.50 in Holstein herds and $12.83 in Ayrshire herds). Key words: Dairy cattle, economic value, field-recorded data, profitability, estimated breeding value

Data breach incidents are reported in the media to be on the rise with continuously increasing numbers. Additionally, data breaches serve a major negative impact to organizations. This study focuses on combining experience in data analytics, visualization, and quantitative analysis for business intelligence in the context of cybersecurity big-data over a period of 15-years. A large data set containing 9,015 data breaches was provided via the Privacy Rights Clearinghouse data breach database from the start of 2005 to the end of 2019. The aim of this work was to slice the data as well as represent it into a business-related visualization using time-series analysis that can help executives understand complex cybersecurity breaches, their impact, and their trend over time. We have created visualization figures along with explanations of what each visualization means in the context of cyber-attacks over time. This project was set to serve as a breakdown of the important findings from the Privacy Rights Clearinghouse data breach database of over 15-years. These findings are communicated through both key numbers and quantitative analyses for business intelligence. While our project does not cover every aspect of the dataset (due to its significant size), it serves more as a focus on one particular part of the data: incident types and their volume over the 15-year timeframe to help business executives visualize cybersecurity trends. This paper ends with a conclusion and discussion on how such cybersecurity visualizations can help industries along with future research needed.
