Based on the data of Chinese A-share listed companies over the period 2014–2018, the study empirically tests the impact of regional credit information sharing on the cash holding level of enterprises. We find a significant negative correlation between credit information sharing and corporate cash holdings, indicating that improving the level of credit information sharing can significantly reduce the level of corporate cash holdings. The higher the level of credit information sharing, the better the external financing environment for enterprises. Therefore, they will choose to hold less cash, and will invest more to higher profitable assets. Distinguishing the nature of equity, we further find that the negative relationship exists in both state-owned enterprises (SOEs) and non-state-owned enterprises(N-SOEs), but it is more significant in the former. Financing problems faced by N-SOEs are more prominent. Improving credit information sharing should have a more significant positive impact on financing for N-SOEs. Therefore, the decline in the optimal cash of N-SOEs should be more significant, but our study finds that SOEs have a greater decline. This shows that the impact of improving credit information sharing on the corporate cash holding level is not single. Although improving the level of credit information sharing is more conducive to improving the financing environment of N-SOEs, it also changes the motives of N-SOEs to hold cash, which greatly strengthens the motivation for having a first-mover advantage and improves the competitive advantage. Therefore, the negative impact of credit information sharing on the cash holding level of SOEs is even greater.
本研究基于2014-2018年中国a股上市公司数据,实证检验区域信用信息共享对企业现金持有水平的影响。我们发现信用信息共享与企业现金持有量之间存在显著的负相关关系,表明提高信用信息共享水平可以显著降低企业现金持有量水平。信用信息共享程度越高,企业外部融资环境越好。因此,他们会选择持有较少的现金,并将更多的投资于利润更高的资产。在区分股权性质的基础上,我们进一步发现国有企业和非国有企业都存在股权负向关系,但非国有企业股权负向关系更为显著。非国有企业面临的融资问题更为突出。改善信用信息共享对非国有企业融资应产生更显著的积极影响。因此,非国有企业的最优现金下降幅度应该更大,但我们的研究发现国有企业的最优现金下降幅度更大。这表明,改善信用信息共享对企业现金持有水平的影响不是单一的。虽然提高信用信息共享水平更有利于改善n型国有企业的融资环境,但同时也改变了n型国有企业持有现金的动机,大大增强了获得先发优势的动机,提高了竞争优势。因此,信用信息共享对国有企业现金持有水平的负面影响更大。

In today's environment of longer human life and higher average age, the general family does not have enough ability and economic conditions to apply for professional nursing staff to assist in the patient of the elderly in need of long-term care in the home. To maintain the family's income, they have to continue the existing work and send the elderly to the care center. However, there is still a shortage problem of nursing staff, even in nursing centers, because each nurse needs to take care of several patients with dealing the related medical matters at the same time. We found that the physical condition of each patient is different. In this paper, the data function and algorithm propose as the basis of data analysis. We can turn the physical condition of each patient into relevant data and analyze the corresponding data. In this way, we can find out the abnormal condition of the patient's body early, which is helpful for the prevention of accidents. After data analysis, if the patient's BFI continues in the stable area in the past month, some detection of Body Function can be omitted. This approach can not only appropriately improve work efficiency but also reduce the workload of nursing staff. Finally, we establish the management mode of medical manpower scheduling then the medical manpower-shortage problem would adjust appropriately.
在人类寿命延长、平均年龄提高的今天,一般家庭没有足够的能力和经济条件来申请专业的护理人员来协助家中需要长期护理的老年人患者。为了维持家庭的收入,他们不得不继续现有的工作,并将老人送到护理中心。然而,即使在护理中心,仍然存在护理人员短缺的问题,因为每个护士需要同时照顾几个病人,处理相关的医疗事宜。我们发现每个病人的身体状况是不同的。本文提出了数据函数和算法,作为数据分析的基础。我们可以将每个患者的身体状况转化为相关数据,并分析相应的数据。这样,我们可以及早发现病人身体的异常情况,有助于预防事故的发生。经数据分析,如果近一个月患者BFI持续在稳定区域,则可以省略部分Body Function检测。这种方法既能适当提高工作效率,又能减轻护理人员的工作量。最后,建立医疗人力调度管理模式,对医疗人力短缺问题进行适当调整。

The pandemic shifted the education paradigm to online classes. One of the requirements of e-education is to have a reliable Internet connection. The Internet has been a vital fount of information transmission and connection in the world wide web that digitized matrices around the world where Internet Service Providers (ISPs) are the rulers for the propagation of Internet access. With the Philippines having various ISPs, Filipinos may find it hard to choose who's the unrivaled as there are also abundant factors to say a telecommunication company is the finest. This study's foremost objective is to conduct a comparative analysis within the topmost selling ISPs in the Philippines by the means of customer satisfaction. These ISPs ranked as the top four (4) telecommunication companies in the Philippines. The study was able to identify that primarily, there was no significant difference among the Internet service providers involved for all factors that could potentially influence customer satisfaction hence, the factors used to identify the customer satisfaction namely - reliability, network coverage, Internet speed, Internet pricing, impact of Internet service, and service quality revealed to greatly affect the consumers ideal choice of Internet provider. In conclusion, it is deemed that this study will increase awareness on how telecommunication companies regulate connections for Filipino Internet service users with the expected dynamic rise of Internet usage. This will serve as a compass to the different telecommunication companies, and will give an understanding on how ISPs’ impact the effectiveness of e-education in the Philippines.
疫情使教育模式转向了在线课程。电子教育的要求之一是要有可靠的互联网连接。互联网已经成为万维网中信息传输和连接的重要源泉,万维网使世界各地的矩阵数字化,互联网服务提供商(isp)是互联网接入传播的统治者。由于菲律宾有各种各样的互联网服务提供商,菲律宾人可能会发现很难选择谁是无与伦比的,因为也有很多因素可以说电信公司是最好的。本研究的首要目标是通过客户满意度的方式对菲律宾最畅销的isp进行比较分析。这些isp在菲律宾排名前四(4)电信公司。研究发现,互联网服务供应商所涉及的所有可能影响客户满意度的因素基本上没有显著差异,因此,用于识别客户满意度的因素-可靠性,网络覆盖,互联网速度,互联网价格,互联网服务的影响和服务质量显示出极大地影响消费者对互联网服务供应商的理想选择。综上所述,我们认为这项研究将提高人们对电信公司如何规范菲律宾互联网服务用户连接的认识,随着互联网使用的预期动态增长。这将作为不同电信公司的指南针,并将使人们了解互联网服务提供商如何影响菲律宾电子教育的有效性。

Blended learning is always a significant method of learning and teaching in education. This method combines the advantages of online and face-to-face learning models to improve students' interest in learning and teaching results. Because the course ‘Principle of Computer Composition’ is extensive, which is not easy to understand and absorb in the process of learning, students need more basic knowledge in learning. Therefore, we establish a blended learning platform for the course, the factors such as learning courses, learning media, and learning environment would be optimized. Utilizing blended learning modules, for instance, ‘e-learning platform’, ‘online class group’, ‘face-to-face classes’, ‘validation in experiments’, ‘discussion of course content’, and ‘learning examination’, we can optimize the teaching process and effect, and improve students' interest in learning and learning impact. At the end of the blended learning module, we feedback the student's learning data to the teacher who obtains the distribution of students' academic achievement through statistical analysis as a reference for adjusting teaching content, progress, and methods.
混合式学习一直是教育教学中一种重要的学习方法。这种方法结合了在线和面对面学习模式的优点,提高了学生的学习兴趣和教学效果。由于《计算机作文原理》这门课程内容广泛,在学习过程中不容易理解和吸收,学生在学习中需要更多的基础知识。因此,我们建立了课程的混合式学习平台,对学习课程、学习媒介、学习环境等因素进行优化。利用“网络学习平台”、“在线班群”、“面授”、“实验验证”、“课程内容讨论”、“学习考试”等混合学习模块,优化教学流程和效果,提高学生的学习兴趣和学习效果。在混合学习模块的最后,我们将学生的学习数据反馈给教师,教师通过统计分析得出学生的学习成绩分布,作为调整教学内容、进度和方法的参考。

Sentiment analysis is a task of identifying the sentiments in text which is often applied to analyzing text in social media, customer feedbacks, and product reviews. Various studies have explored how sentiment analysis can automatically done by using machine learning techniques. However, there has been few attempts in implementing sentiment analysis on multilingual text. Furthermore, most of the existing works uses labelled data to train and develop machine learning models for sentiment analysis. Using labelled data are often expensive and time consuming. In this study, a sentiment analysis model for multilingual text using semi-supervised machine learning was explored. The data used is composed of 50,788 tweets about COVID-19, these are cleaned by removing unnecessary characters, stop words, and emojis. After cleaning, the language of each tweet was identified, all tweets that are not written in Filipino or English were removed from the dataset. Afterwards, the tweets were all translated in English in preparation for the annotation phase. This study used an open-source tool, TextBlob, in annotating the tweets. TextBlob outputs the polarity of the text in vector representation. The TextBlob annotation were then validated by human experts through an inter-rater agreement. The level of agreement between the human annotations and TextBlob annotations have a substantial agreement with 0.78 Fleiss’ Kappa value. Classifier models were developed using various machine learning algorithms. Based on the results of the experiment, SVC is the best performing model with count vectorizer as feature with an accuracy, precision, recall, and F1-score of 95%. For future work, fine tuning hyperparameters to optimize the models can be considered.
情感分析是一项识别文本情感的任务,通常用于分析社交媒体、客户反馈和产品评论中的文本。各种研究已经探索了如何通过使用机器学习技术自动完成情感分析。然而,对多语言文本进行情感分析的尝试很少。此外,大多数现有工作使用标记数据来训练和开发用于情感分析的机器学习模型。使用标记数据通常既昂贵又耗时。本研究探索了一种基于半监督机器学习的多语言文本情感分析模型。使用的数据由50,788条关于COVID-19的推文组成,这些推文通过删除不必要的字符、停止词和表情符号进行清理。清理后,每条推文的语言被识别,所有不是用菲律宾语或英语写的推文都从数据集中删除。之后,这些推文都被翻译成英文,为注释阶段做准备。这项研究使用了一个开源工具TextBlob来注释推文。TextBlob以向量表示形式输出文本的极性。然后,TextBlob注释由人类专家通过评估者之间的协议进行验证。人类注释和TextBlob注释之间的一致性水平与0.78 Fleiss的Kappa值有很大的一致性。使用各种机器学习算法开发分类器模型。实验结果表明,以计数矢量器为特征的SVC是表现最好的模型,准确率、精密度、召回率和f1分数均达到95%。对于未来的工作,可以考虑微调超参数来优化模型。

Digital assessment (DA) has been recognized as one of the most critical elements of modern education due to the ever-growing uptake of information and communication technologies in learning and teaching. This article provides a systemic approach to navigating and enhancing the use of DA in the higher education context. A multi-dimensional framework for DA development is first introduced which not only captures important aspects of DA but also highlights the trade-off between these competing dimensions. We then take a closer look at the online testing landscape and use this framework to analyze the pedagogical and technical dimensions of DA in practice.
由于在学习和教学中越来越多地采用信息和通信技术,数字评估(DA)已被公认为现代教育中最关键的要素之一。本文提供了一种在高等教育环境中导航和增强数据分析使用的系统方法。首先介绍了数据处理开发的多维框架,它不仅捕获了数据处理的重要方面,而且还强调了这些相互竞争的维度之间的权衡。然后,我们仔细研究了在线测试环境,并使用这个框架来分析实践中数据分析的教学和技术层面。

The growing number of cases of COVID-19 has prompted the government to develop and deploy digital contact tracing applications. [1] The dominant explanation of these measures is mitigating the transmission of the novel coronavirus (COVID-19). [2] Contact tracing is crucial in dealing with a pandemic because it allows rapid detection of cases based on information gathered from affected individuals about other people they may have had recent contact with. Advances in digital technologies have made it possible to use cellular phones in the contact tracing process. The previous study has proved the effectiveness of the contact tracing application in various countries like Singapore and United Kingdom. Having said this, the objective of this study is to determine the efficacy of StaySafe PH in reducing the ballooning cases of COVID-19 in Barangay Bagong Silangan, Quezon City. StaySafe PH is a contact tracing application with medical consultation and allows users to report problems regarding their health conditions easily. The respondents were composed of 55 (fifty-five) residents of Barangay Bagong Silangan, whose ages are within the bracket of 18 to 59 years old. To gather the necessary data needed, the proponents created and administered a questionnaire to the subjects, which focused on the respondents' experience in using the StaySafe PH. The design used by the researcher is correlational, which gathers quantifiable information that can be used for statistical interference through data analysis. In addition, the researchers applied a probability sampling technique in this study. In findings and analysis of the data, most of the respondents are using StaySafe PH, which is thirty-six (36) percent at the same time believed that the application could help in flattening the curve and saving more lives. Furthermore, it is decided that StaySafe PH is effective and safe to use.
COVID-19病例的不断增加促使政府开发和部署数字接触者追踪应用程序。[1]对这些措施的主要解释是减轻新型冠状病毒(COVID-19)的传播。[2]接触者追踪对于应对大流行至关重要,因为它可以根据从受影响的个人收集的关于他们最近可能接触过的其他人的信息快速发现病例。数字技术的进步使得在接触追踪过程中使用移动电话成为可能。先前的研究已经证明了新加坡和英国等国家接触者追踪应用的有效性。话虽如此,本研究的目的是确定StaySafe PH在减少奎松市Barangay Bagong Silangan的COVID-19病例激增方面的功效。StaySafe PH是一个医疗咨询的接触追踪应用程序,允许用户轻松报告有关他们健康状况的问题。受访者由55名(55名)Barangay Bagong Silangan居民组成,他们的年龄在18至59岁之间。为了收集所需的必要数据,支持者创建并管理了一份调查问卷,主要关注受访者使用StaySafe ph的经验。研究人员使用的设计是相关的,它收集可量化的信息,可通过数据分析用于统计干扰。此外,研究人员在本研究中应用了概率抽样技术。在调查结果和数据分析中,大多数受访者都在使用StaySafe PH,其中36%的人同时认为该应用程序可以帮助平坦曲线并挽救更多生命。此外,决定StaySafe PH是有效和安全的使用。
