Mobile health applications can allow for care providers to reach a broader audience than in-person interventions can. Additionally, in times of a pandemic like COVID-19, care can be provided in a safer way for providers and for patients. A mobile health app was developed to teach about the prevention and treatment of hypertension and diabetes. This app was specifically designed and tailored for an Indian population since these noncommunicable diseases are large contributors to death in Indian adults. Previous work targeted an Indian population in India, but this work explores the impact of the app with a migrant Indian working population in Hong Kong. Participants showed statistically significant learning gains in knowledge about both hypertension and diabetes as a result of using the app’s animations and games. This demonstrates the effectiveness of mobile health apps at providing targeted healthcare education.
移动医疗应用程序可以让护理提供者接触到比面对面干预更广泛的受众。此外,在COVID-19等大流行时期,可以以更安全的方式为提供者和患者提供护理。开发了一款移动健康应用程序,用于教授高血压和糖尿病的预防和治疗。这个应用程序是专门为印度人设计和定制的,因为这些非传染性疾病是印度成年人死亡的主要原因。之前的工作是针对印度的印度人口,但这项工作探讨了该应用程序对在香港工作的印度移民人口的影响。通过使用该应用程序的动画和游戏,参与者在高血压和糖尿病知识方面的学习成绩在统计上都有显著提高。这证明了移动健康应用程序在提供有针对性的医疗保健教育方面的有效性。

An increasing number of companies offer their capabilities as Web services and publish them through public registries. Such Web services enable users to access and manipulate online data programmatically. Moreover, they can be deployed in service-based systems (SBS) or composite web applications and mashups to offer value-added services. A crucial step in deploying Web services is the Web service Discovery. Selecting the best Web service candidates to address the needs of service requesters (e.g., SBS designers) is an important task in SBSs and can influence the quality of the resulting composite web application. So far proposed solutions for addressing this challenge, which are mainly categorized into Syntactic-based and Semantic-based, are either too complex for end-users which hinders their large-scale adaptation or suffer from low precision and recall. Considering the recent trend of shifting the development activities more and more towards the end-users, we propose an approach based on chat-bot technology to allow end-users to select a set of best-fitting Web services according to their goals. Conversational Interfaces also known as chatbots aim at providing users a more natural framework to interact with web applications and devices. The advantage of DISCO compared to the state-of-the-art approaches is leveraging the natural language as the communication medium and alleviating the need for end-users to have technical knowledge about the service’s structure and location. We conducted sets of experiments by recruiting 8 test subjects to query the chatbot. The results achieve high precision and recall.
越来越多的公司将其功能作为Web服务提供,并通过公共注册中心发布。这样的Web服务使用户能够以编程方式访问和操作在线数据。此外,它们可以部署在基于服务的系统(SBS)或组合web应用程序和mashup中,以提供增值服务。部署Web服务的关键步骤是Web服务发现。选择最佳的Web服务候选者来满足服务请求者(例如,SBS设计人员)的需求是SBS中的一项重要任务,并且会影响生成的复合Web应用程序的质量。目前针对这一挑战提出的解决方案主要分为基于句法和基于语义两大类,但对于最终用户来说,这些解决方案要么过于复杂,阻碍了他们的大规模适应,要么精度和召回率较低。考虑到最近将开发活动越来越多地转移到最终用户的趋势,我们提出了一种基于聊天机器人技术的方法,允许最终用户根据他们的目标选择一组最适合的Web服务。会话界面也被称为聊天机器人,旨在为用户提供一个更自然的框架来与web应用程序和设备进行交互。与最先进的方法相比,DISCO的优势在于利用自然语言作为沟通媒介,减轻了最终用户对服务结构和位置的技术知识的需求。我们进行了一组实验,招募了8个测试对象来查询聊天机器人。结果具有较高的查全率和查准率。

Over the last 20 years scientists from many disciplines have proposed mechanisms that allow decision-makers to negotiate directly on common outcomes. The Internet-enabled versions of these mechanisms can allow citizens to practice direct democracy and thus increase participation in governance. This study investigates the information requirements of one of these mechanisms – the Online Compensation Election. More specifically the study tests if the level of detail of the information available to a voter about the preference intensities of other voters affects voting behavior. We find that a decrease in the granularity of the real preference intensity information about others does not affect voting behavior and the referendum’s compensation outcomes We discuss the implications of these results and possible future directions for research.
在过去的20年里,来自许多学科的科学家提出了允许决策者直接就共同结果进行谈判的机制。这些机制的互联网版本可以让公民实践直接民主,从而增加对治理的参与。本研究探讨了其中一种机制——在线补偿选举的信息需求。更具体地说,这项研究测试了选民对其他选民的偏好程度的信息的详细程度是否会影响投票行为。我们发现,关于他人的真实偏好强度信息粒度的减少不会影响投票行为和公投的补偿结果。我们讨论了这些结果的含义和可能的未来研究方向。

We propose a dynamically prioritized failure management method according to the reliability model that the failure rate of virtual machine varies in its life cycle. When using a combination of server monitoring with ping and network connection check with Ethernet OAM, the system sets higher priorities to the port connected to a long running server, and the port within a certain time after the connection change or virtual machine addition is set. The system then selects the ports from the higher priority port to be monitored by Ethernet OAM. As a result of the evaluation by the simulation, by dynamically selecting the port to be monitored for Ethernet OAM using the proposed method, it was confirmed that more than a third of all failures were detected with Maintenance End Points which number is only a tenth of that of servers in a data center. In the data center for cloud services running many VMs, it is possible to shorten the recovery from VM failure while suppressing the number of objects monitored by Ethernet OAM by using this method.
根据虚拟机在其生命周期内故障率变化的可靠性模型,提出了一种动态优先级故障管理方法。当将服务器监控与ping和网络连接检查与以太网OAM结合使用时,系统会为连接到长时间运行的服务器的端口设置更高的优先级,并且在更改连接或添加虚拟机后的一定时间内设置该端口。然后系统从高优先级端口中选择端口,由以太网OAM监控。仿真结果表明,采用本文提出的方法动态选择以太网OAM监控端口,通过维护端点检测到的故障超过三分之一,而维护端点的数量仅为数据中心服务器数量的十分之一。在运行多虚拟机的云服务数据中心中,使用该方法可以缩短虚拟机故障的恢复时间,同时抑制以太网OAM监控的对象数量。

Social networks play an important role in the life of today's societies and consumers are engaging more online with brands. Brands create and share information and special video ads on social networks, and, in the context of the COVID-19 pandemic, social networks allow brands to communicate with their consumers simply and quickly. Therefore, creativity and narrative structures are important for consumers. Brands are producing video ads that show consumers’ day context in order to obtain greater social media engagement. Considering that, this paper aims to study whether that goal is being achieved. The empirical research, from which we obtained 427 responses and which was tested using structural equations using the AMOS software, allows to conclude that creativity, the structure of the narrative and the consumer's congruence with the brand are determinants of engagement in social media. Further, presents practical and theoretical recommendations.
社交网络在当今社会的生活中扮演着重要的角色,消费者越来越多地在网上与品牌互动。品牌在社交网络上创建和分享信息和特殊视频广告,在2019冠状病毒病大流行的背景下,社交网络使品牌能够简单、快速地与消费者沟通。因此,创意和叙事结构对消费者来说很重要。为了获得更大的社交媒体参与度,品牌正在制作视频广告,展示消费者的日常环境。鉴于此,本文旨在研究这一目标是否正在实现。从实证研究中,我们获得了427个回应,并使用AMOS软件使用结构方程进行了测试,可以得出这样的结论:创造力、叙事结构和消费者与品牌的一致性是社交媒体参与度的决定因素。并提出了实践和理论建议。

Personalization depends on prior knowledge about information retrieval and web search and aims to build accurate and detailed user models. Thus, in the first step, it has to present a definition of a user model and in the next step, the contexts of what type of data is used in user-profiles and the models to represent them have to be provided. The structure of the user profile always is an important issue because of its impact on ranking performance. It is clear that if the algorithms used in the user model are more accurate and robust, the user model and personalized services will result in better efficiency and quality. Therefore, creating an efficient user profile is a challenge. Our motivation is to develop a keyphrase-based profile that operates on documents to improve personalization. These profiles are created using the keyphrase based models on the query log, as long-term, short-term and session-term to consider user interest in different time intervals to compare efficiency. Besides, we conduct comparative research on topic-based user profiles, intending to compare keyphrase-based and topic-based profiles in the personalization process. The results obtained more accuracy in session-based models by 13% in mean reciprocal rank and 14% in normalized discounted cumulative gain than long-based models.
个性化依赖于对信息检索和网络搜索的先验知识,旨在建立准确和详细的用户模型。因此,在第一步中,它必须提供用户模型的定义,在下一步中,必须提供用户概要文件中使用的数据类型的上下文以及表示它们的模型。用户配置文件的结构一直是一个重要的问题,因为它影响排名性能。很明显,如果用户模型中使用的算法更准确和鲁棒,用户模型和个性化服务将带来更好的效率和质量。因此,创建一个高效的用户配置文件是一个挑战。我们的动机是开发一个基于关键短语的配置文件,它可以在文档上操作以改进个性化。这些概要文件是在查询日志上使用基于关键字短语的模型创建的,分为长期、短期和会话期,以考虑用户在不同时间间隔内的兴趣,以比较效率。此外,我们还对基于主题的用户档案进行了对比研究,旨在比较基于关键字的用户档案和基于主题的用户档案在个性化过程中的差异。结果表明,基于会话的模型比基于长期的模型在平均倒数秩和标准化贴现累积增益方面的准确率分别提高了13%和14%。

The aggregation and visualization of data are part of one of the most important fields of Data Science’s application today. This class of tools evidences its importance in the area of public health, especially in the context of epidemics and pandemics. However, there are several issues in accessing reliable data, such as diverse sources, economic interests, and technical difficulties. This work proposes and explores the technological choices for the implementation of a system in which, collaboratively, users provide health information, which are made available through panels with scalability in access and flexibility in the analysis, allowing a macro view of the situation. Also, with the use of these visualizations and mobile application technologies, users can take advantage of services such as monitoring health status and sending alerts of emergency situations.

DO NOT TRUST ME: HOW NEWS READERS PERCEIVE AND RECOGNIZE NATIVE ADVERTISING 不要相信我:新闻读者如何感知和识别原生广告

Native advertising has developed into a popular marketing tool for publishers and advertisers. However, its success is also criticized, because it is assumed that readers are not able to identify these contributions as advertising. The purpose of this study is to outline whether readers recognize native ads and how it affects the trust in the content of the articles. It is also intended to help advertisers and publishers better understand the impact of native advertising and its disclosure on readers. The method of this research is based on a theoretical and empirical approach. For the theoretical aspects of this study, a literature analysis was applied, whereas a quantitative analysis in the form of an experiment was conducted for the empirical part. The study shows that a majority of the sample did not recognize the article as native ad. After the disclosure of native advertising a decrease in trust could be determined. However, this is not significant, which means that the majority of readers still trust the content of the article. It is also found that respondents for whom the content of the article is relevant are less concerned about the article being paid for. Thus, it can be said that the success of native advertising may in fact be related to the inability of readers to recognize this type of advertising. The increased recognition of such contributions, however, does not necessarily lead to a reduced success of native advertising, because the majority of contributions are trusted even after disclosure.
原生广告已经发展成为出版商和广告商的流行营销工具。然而,它的成功也受到了批评,因为它假定读者无法将这些贡献识别为广告。本研究的目的是概述读者是否认可原生广告,以及它如何影响对文章内容的信任。它还旨在帮助广告商和出版商更好地了解原生广告及其披露对读者的影响。本研究采用理论与实证相结合的方法。本研究的理论部分采用文献分析,实证部分采用实验形式的定量分析。研究表明,大多数样本并没有认出这篇文章是原生广告。在披露原生广告后,可以确定信任度的下降。然而,这并不显著,这意味着大多数读者仍然信任文章的内容。研究还发现,对于文章内容相关的受访者来说,他们不太关心文章的付费情况。因此,可以说,原生广告的成功实际上可能与读者无法识别这种类型的广告有关。然而,对这些贡献的更多认可并不一定会导致本地广告的成功减少,因为即使在披露之后,大多数贡献也是可信的。
