Abstract Non-expert scientists are frequently involved in research requiring data acquisition over large geographic areas. Despite mutual benefits for such "citizen science", barriers also exist, including 1) difficulty maintaining user engagement with timely feedback, and 2) the challenge of providing non-experts with the means to generate reliable data. We have developed a system that addresses these barriers. Our technologies, KnoWare and InSpector, allow users to: collect reliable scientific measurements, map geo-tagged data, and intuitively visualize the results in real-time. KnoWare comprises a web portal and an iOS app with two core functions. First, users can generate scientific 'queries' that entail a call for information posed to a crowd with customized options for participant responses and viewing data. Second, users can respond to queries with their GPS-enabled mobile device, which results in their geo- and time-stamped responses populating a web-accessible map in real time. KnoWare can also interface with additional applications to diversify the types of data that can be reported. We demonstrate this capability with a second iOS app called InSpector that performs quantitative water quality measurements. When used in combination, these technologies create a workflow to facilitate the collection, sharing and interpretation of scientific data by non-expert scientists. Keywords: Citizen Science, Cell-phone Spectrometer, Water Contaminant Analysis, Web and Mobile Development, Visualization Introduction The prevalence of smartphones represents an opportunity to gather, create, and consume data from individuals on a scale that has not previously been available. Even the 'average' mobile devices in widespread use have significant computing power and are typically GPS-enabled. Scientific research that requires widespread sampling over geographic areas can benefit greatly by mobilizing members of the population equipped with these devices to conduct scientifically useful measurements or activities. Data generated in this way can complement existing data collection methods. One key advantage of these 'citizen science' initiatives is that sourcing large groups of individuals is an efficient strategy to collect large-scale data sets because contributors typically volunteer their time in exchange for meaningful participation. However, in spite of the benefits, multiple barriers work against increased prevalence of citizen science initiatives, including 1) the difficulty maintaining prolonged user engagement with meaningful feedback, and 2) the challenge of providing non-experts with the means to collect reliable data. We have developed technologies to directly address these barriers by providing 'citizen scientists' with 1) an easy-to-use mechanism to participate in scientific investigations with real time visual feedback, and 2) software and a device that interface with iPhones to collect reliable scientific measurements from color-based test kit
非专家科学家经常参与需要在大地理区域获取数据的研究。尽管这种“公民科学”有共同的利益,但也存在障碍,包括1)难以通过及时的反馈维持用户的参与,以及2)向非专家提供生成可靠数据的方法的挑战。我们已经开发了一个解决这些障碍的系统。我们的技术,KnoWare和InSpector,允许用户:收集可靠的科学测量,绘制地理标记数据,并直观地实时可视化结果。KnoWare包括一个门户网站和一个具有两个核心功能的iOS应用程序。首先,用户可以生成科学的“查询”,这需要向人群提供信息,并为参与者的回答和查看数据提供定制选项。其次,用户可以用带有gps功能的移动设备回答问题,这将导致他们的地理和时间戳的回答实时填充到网络可访问的地图中。KnoWare还可以与其他应用程序连接,以使可以报告的数据类型多样化。我们用另一款名为InSpector的iOS应用程序演示了这一功能,该应用程序执行定量水质测量。当结合使用时,这些技术创建了一个工作流程,以方便非专业科学家收集、共享和解释科学数据。关键词:公民科学,手机光谱仪,水污染分析,网络和移动开发,可视化介绍智能手机的普及为收集、创建和使用个人数据提供了一个前所未有的机会。即使是广泛使用的“普通”移动设备也具有强大的计算能力,并且通常具有gps功能。需要在地理区域进行广泛抽样的科学研究可以通过动员配备这些设备的人口成员进行科学上有用的测量或活动而大大受益。以这种方式产生的数据可以补充现有的数据收集方法。这些“公民科学”计划的一个关键优势是,寻找大量个人是收集大规模数据集的有效策略,因为贡献者通常自愿献出自己的时间,以换取有意义的参与。然而,尽管有这些好处,许多障碍阻碍了公民科学计划的普及,包括1)难以通过有意义的反馈维持长期的用户参与,以及2)向非专家提供收集可靠数据的方法的挑战。我们已经开发了直接解决这些障碍的技术,为“公民科学家”提供1)一个易于使用的机制,通过实时视觉反馈参与科学调查,以及2)软件和设备,与iphone接口,从广泛使用的基于颜色的测试套件中收集可靠的科学测量数据。我们的技术目前专注于允许用户记录水质测量,因为这样的数据收集需要大量的、重复的测量,并且有许多现有的公民科学计划已经专注于可能受益的水质。我们的技术平台名为KnoWare,包括一个配对的门户网站和用于数据可视化和制图的iOS应用程序。在本报告中,我们将KnoWare与我们创建的另一个iOS应用程序(InSpector)结合使用,使用附加设备处理iPhone相机拍摄的图像。InSpector应用程序允许用户获得可靠的比色水质测试读数,目前依赖于主观颜色比较。这些技术一起工作,为非专业的公民科学家收集和解释环境水质数据提供了一个引人入胜的工作流程。我们开发的技术促进了基于公民科学的数据收集工作,其动机如下:增加STEM领域的曝光率和“素养”,让更广泛的公众参与科学努力以推进研究的潜在影响,以及让我们自己机构的学生参与开发具有“现实世界”应用的软件和设备的机会。…

Abstract This study investigates the skill sets necessary for entry level systems analysts. Towards this end, the study combines two sources of data, namely, a content analysis of 200 systems analysts' online job advertisements and a survey of 20 senior Information Systems (IS) professionals. Based on Chi-square tests, the results reveal that most employers prefer entry level systems analysts with an undergraduate Computer Science degree. Furthermore, most of the employers prefer entry level systems analysts to have some years of experience as well as industry certifications. The results also reveal that there is a higher preference for entry level systems analysts who have non-technical and people skills (e.g., problem solving and oral communication). The empirical results from this study will inform IS educators as they develop future systems analysts. Additionally, the results will be useful to the aspiring systems analysts who need to make sure that they have the necessary job skills before graduating and entering the labor market. Keywords: System Analysts, Information Systems, Education, Skills, Content Analysis, Empirical Study Introduction The Information Systems major (we hereafter use IS to refer to Management Information Systems, Information Systems, Computer Information Systems, as well as the other variants of the IS related majors) is characterized by rapid growth and constant evolution. Likewise, systems analysts are required to have a range of skills and knowledge and to constantly update their skills and knowledge in order to remain competent (Joseph, Ang, Change, & Slaughter, 2010). The skills and knowledge requirements for system analysts are encapsulated in the IS 2010 model curriculum (Topi et al., 2010), in which System Analysis & Design (SA&D) is described as the course that, "....discusses the processes, methods, techniques and tools that organizations use to determine how they should conduct their business, with a particular focus on how computer-based technologies can most effectively contribute to the way business is organized. The course covers a systematic methodology for analyzing a business problem or opportunity, determining what role, if any, computer-based technologies can play in addressing the business need, articulating business requirements for the technology solution, specifying alternative approaches to acquiring the technology capabilities needed to address the business requirements, and specifying the requirements for the information systems solution in particular, in-house development, development from third-party providers, or purchased commercial-off-the-shelf (COTS) packages.... " Based on the course description, it is apparent that students enrolled in the SA&D course(s) should have a myriad set of both technical and business oriented skills and knowledge.

摘要本研究调查了入门级系统分析师所需的技能集。为此,该研究结合了两个数据来源,即对200名系统分析师在线招聘广告的内容分析和对20名高级信息系统(IS)专业人员的调查。基于卡方检验的结果显示,大多数雇主更喜欢具有计算机科学本科学位的入门级系统分析师。此外,大多数雇主更喜欢有多年经验和行业认证的入门级系统分析师。结果还显示,具有非技术和人际关系技能(例如,解决问题和口头沟通)的入门级系统分析师更受青睐。本研究的实证结果将为信息系统教育者培养未来的系统分析师提供信息。此外,研究结果对那些有抱负的系统分析师也很有用,他们需要确保自己在毕业进入劳动力市场之前具备必要的工作技能。信息系统专业(以下简称信息系统专业,包括管理信息系统、信息系统、计算机信息系统以及其他信息系统相关专业的变体)具有快速发展和不断发展的特点。同样,系统分析师需要具备一系列的技能和知识,并不断更新他们的技能和知识,以保持竞争力(Joseph, Ang, Change, & Slaughter, 2010)。系统分析师的技能和知识要求被封装在IS 2010模型课程中(Topi et al., 2010),其中系统分析与设计(SA&D)被描述为“....”讨论组织用来确定他们应该如何开展业务的过程、方法、技术和工具,特别关注基于计算机的技术如何最有效地促进业务组织方式。本课程涵盖了分析业务问题或机会的系统方法,确定基于计算机的技术在解决业务需求方面可以发挥的作用(如果有的话),阐明技术解决方案的业务需求,指定获取解决业务需求所需的技术能力的替代方法,并指定信息系统解决方案特别是内部开发的需求。第三方提供商的开发,或者购买的商用现货(COTS)包....”根据课程描述,很明显,参加SA&D课程的学生应该拥有大量的技术和业务导向的技能和知识。因此,本研究的目的在于找出资讯系统专业人员与劳工市场对入门级系统分析师的技能和知识要求是否有共识。这个问题的答案对未来的学生和即将毕业的大四学生都很重要,他们正在为就业市场做准备。这个问题还应该使那些教授SA&D的人能够衡量他们是否为系统分析师做好了充分的准备,以利用就业市场上的空缺职位。下面的部分提供了关于系统分析师的文献的简要回顾。然后,给出了研究方法、分析、讨论和结论。当前的信息系统2010 (IS2010)模型课程将系统分析与设计(SA&D)指定为信息系统课程的七门核心课程之一(Topi et al., 2010)。将SA&D指定为核心课程与之前的课程(IS97和IS2002)略有偏差,在IS97和IS2002中,SA&D课程与分析和逻辑设计课程紧密匹配(Gorgone, Davis, Valacich, Topi, Feinstein & Longenecker, 2003)。...

Abstract The main aim of this paper is to provide a theoretically and empirically grounded discussion on IT-based organizational creativity support. This study attempts to answer the following questions: (1) what is the issue of organizational creativity and its IT-based support, (2) what is the demand for IT -based organizational creativity support; (3) what are the main determinants and barriers to IT-based organizational creativity support; and (4) what success factors are crucial for IT-based organizational creativity support. This paper presents the analysis results of a survey conducted in 25 selected organizations. The paper provides valuable information on the possibilities of IT applications in organizational creativity support as well as the associated success factors. It makes useful contribution to our better understanding of IT-based organizational creativity support issues. Keywords: Organizational creativity, IT-based organizational creativity support, success factors Introduction Although studies on creativity have been developing for three decades, they have not addressed the essence of organizational creativity and its IT-based support. They have been mainly focused on creative problem solving, creative processes and individual creativity support systems (Cooper, 2000; Dewett, 2003). The issue of IT-based organizational creativity support is still insufficiently investigated. The research studies are fragmented and scattered. Organizational creativity is considered one of the most actively developing research areas. It is asserted that it is a main vehicle of organizational development, the basis for staying in the market and innovative success (Amabile, 1988; Elsbach & Hargadon, 2006; McLean, 2009; Shin & Zhou, 2007). Organizations face the need to constantly generate new and useful ideas that concern products, services, processes, managerial practices as well as competitive strategies. Effective support of acquiring, collecting, storing and analyzing different information resources as well as discovering new knowledge and its rapid dissemination are of crucial importance (Arora & Nandkumar, 2012; Sirmon, Hitt, Ireland, & Gilbert, 2011; Zahra, Sapienza, & Davidsson, 2006). Several arguments can be found in the pertinent literature that Information Technologies (IT) enables organizations faster and easier access to information, improving creativity in business processes, and better communication between employees and all stakeholders (Cooper, 2000; Davenport, 2013). IT enables an organization to search and absorb new knowledge that is needed in organizational creativity and solving business problems. On the other hand, the praxis shows that success from IT-based creativity support is still questionable. Many organizations are not able to make IT an effective tool for creativity support. The reasons for this failure are not clear and still not well investigated. The need for a more systematic and deliberate study of creativity su
摘要本文的主要目的是对基于信息技术的组织创造力支持进行理论和实证的探讨。本研究试图回答以下问题:(1)组织创造力及其IT支持的问题是什么;(2)对IT组织创造力支持的需求是什么;(3) it组织创造力支持的主要决定因素和障碍是什么;(4)哪些成功因素对基于it的组织创造力支持至关重要。本文介绍了在25个选定组织中进行的一项调查的分析结果。本文就信息技术应用于组织创造力支持的可能性以及相关的成功因素提供了有价值的信息。它对我们更好地理解基于It的组织创造力支持问题做出了有益的贡献。虽然对创造力的研究已经发展了三十年,但它们并没有解决组织创造力的本质及其it支持。他们主要关注创造性解决问题,创造性过程和个人创造力支持系统(Cooper, 2000;Dewett, 2003)。基于it的组织创造力支持问题仍然没有得到充分的研究。研究是零散的。组织创造力被认为是发展最为活跃的研究领域之一。有人断言,它是组织发展的主要工具,是留在市场和创新成功的基础(Amabile, 1988;Elsbach & Hargadon, 2006;麦克莱恩,2009;Shin & Zhou, 2007)。组织需要不断地产生有关产品、服务、过程、管理实践以及竞争战略的新的有用的想法。获取、收集、存储和分析不同信息资源以及发现新知识及其快速传播的有效支持至关重要(Arora & Nandkumar, 2012;simon, Hitt, Ireland, & Gilbert, 2011;Zahra, Sapienza, & Davidsson, 2006)。在相关文献中可以找到几个论点,即信息技术(IT)使组织能够更快、更容易地获取信息,提高业务流程中的创造力,以及员工和所有利益相关者之间更好的沟通(Cooper, 2000;达文波特,2013)。IT使组织能够搜索和吸收组织创造力和解决业务问题所需的新知识。另一方面,实践表明,基于it的创新支持的成功仍然值得怀疑。许多组织不能使IT成为支持创造力的有效工具。这种失败的原因尚不清楚,也没有得到很好的调查。对组织创造力支持进行更系统、更审慎的研究是至关重要的。本文的主要任务是对组织创造力及其信息技术支持进行探讨。这一讨论使我们能够回答以下问题:(1)组织创造力及其基于IT的支持的问题是什么?(2)基于IT的组织创造力支持的需求是什么?(3) it组织创造力支持的主要决定因素和障碍是什么;(4)在基于it的组织创造力支持中,哪些成功因素至关重要。寻找这些问题的答案主要是在理论和实证基础上进行的。首先,对相关文献进行批判性审查,以确定组织创造力问题及其计算机支持。搜索合适的文献从不同的书目数据库开始,例如EBESCOhost、Emerald Management 75、ISI Web of Knowledge、ProQuest和Scopus。…

Group work can provide a valuable learning experience, one that is especially relevant for those preparing to enter the information system workforce. While much has been discussed about effec-tive means of delivering the benefits of collaborative learning in groups, there are some problems that arise due to pragmatic environmental factors such as the part time work commitments of stu-dents. This study has identified a range of problems and reports on a longitudinal Action Re-search study in two universities (in Australia and the USA). Over three semesters problems were identified and methods trialled using collaborative tools. Several promising solutions are present-ed to the identified problems, including the use of video tutorials and commentary using screen recordings as a means of providing feedback to students.
小组工作可以提供宝贵的学习经验,这对那些准备进入信息系统工作的人来说尤其重要。虽然关于在小组中提供协作学习好处的有效方法已经讨论了很多,但由于实际的环境因素,如学生的兼职工作承诺,出现了一些问题。在澳大利亚和美国两所大学的纵向行动研究中,本研究发现了一系列问题和报告。在三个学期的时间里,他们发现了问题,并使用协作工具对方法进行了试验。针对已发现的问题,提出了几种有希望的解决方案,包括使用视频教程和使用屏幕录音作为向学生提供反馈的手段的评论。

Building an Informing Business School: A Case Study of USF's Muma College of Business 建设一个信息丰富的商学院:以USF的Muma商学院为例

Abstract As the complexity of a system grows, the challenge of informing the stakeholders of that system grows correspondingly. Nowhere is that challenge more daunting than in business education, where globalization, technological innovation, and increasingly complicated regulations continuously transform the business environment facing graduates and practitioners. Informing science theory proposes that different levels of complexity require different channels if effective informing is to be achieved. The paper first examines how two important sources of complexity--the diversity of clients and the ruggedness of the business landscape--are changing, and how these changes demand vastly more interactive informing channels if impact is to be achieved. Using an exploratory case study methodology, it then takes a detailed look at how one institution--the University of South Florida's Muma College of Business--has introduced a variety of new channels, many of which enable informing flows without necessarily directing them, to adapt to these environmental changes. It then considers both outcomes related to these individual informing channels and college-wide outcomes related to a broad and deep mosaic of informing flows. Finally, it considers the question of the resources required to support these new channels and the relationship between resource acquisition and channel introduction. The proposed framework for looking at business school informing channels can be applied by administrators, faculty members, and key stakeholders in understanding, evaluating, and planning programs and activities supporting informing in a complex environment. Ultimately, the informing business school framework may also provide a means for communicating impact to business school accrediting agencies (such as AACSB). Keywords: informing science, informing system, internships, externships, business education, case studies, research, channel, complexity, rugged landscape, business school, impact. Introduction Informing is central to the mission of virtually every educational institution. Recently, however, serious questions are being raised with respect to the impact that higher education is having on its stakeholders (Gill, 2010). In the U.S., high student loan default rates, failure of many students--particularly disadvantaged students--to graduate, the growth in the number of administrators, and the production of expensive research that appears to serve no useful purpose are all symptomatic of these concerns. Nowhere are these concerns more apparent than in today's business schools. Accrediting agencies, such as AACSB International, have made impact a top priority in ongoing accreditations (AACSB, 2008, 2015).

随着系统复杂性的增长,告知涉众该系统的挑战也相应增长。在商业教育领域,全球化、技术创新和日益复杂的法规不断改变着毕业生和从业者面临的商业环境,这是最令人生畏的挑战。信息科学理论提出,要实现有效的信息传递,不同的复杂程度需要不同的渠道。本文首先考察了复杂性的两个重要来源——客户的多样性和商业环境的坚固性——是如何变化的,以及如果要实现影响,这些变化如何要求更多的交互式信息渠道。然后,使用探索性案例研究方法,详细研究了南佛罗里达大学Muma商学院(University of South Florida’s Muma College of Business)这一机构是如何引入各种新渠道的,其中许多渠道在没有必要指导的情况下实现了信息流动,以适应这些环境变化。然后,它考虑了与这些个人信息渠道相关的结果,以及与广泛而深刻的信息流马赛克相关的大学范围内的结果。最后,本文考虑了支持这些新渠道所需的资源问题,以及资源获取与渠道引入之间的关系。研究商学院信息渠道的建议框架可以被管理者、教师和主要利益相关者应用于理解、评估和规划在复杂环境中支持信息的项目和活动。最终,通知商学院框架也可能提供一种向商学院认证机构(如AACSB)传达影响的手段。关键词:信息科学、信息系统、实习、实习、商业教育、案例研究、研究、渠道、复杂性、崎岖景观、商学院、影响。提供信息是几乎所有教育机构的核心使命。然而,最近,关于高等教育对其利益相关者的影响,人们提出了严重的问题(吉尔,2010)。在美国,高额的学生贷款违约率,许多学生——尤其是弱势学生——未能毕业,管理人员数量的增加,以及似乎毫无用处的昂贵研究成果的产生,都是这些担忧的症状。这些担忧在当今的商学院中表现得最为明显。认证机构,如AACSB国际,已经将影响作为正在进行的认证的首要任务(AACSB, 2008, 2015)。机构必须证明其对所有关键利益相关者的影响:学生、研究学者群体和实践群体。未能有效地告知这些利益相关者群体中的任何一个都可能导致试用状态,这可能危及机构的声誉,甚至其长期生存。利害攸关,各机构必须调整其通报活动,使其效力最大化,并确保获得有关其效力的证据。从信息科学的角度来看,利益攸关方所经历的环境性质的变化加剧了实现可衡量影响的挑战。特别重要的是这种环境的潜在复杂性。在其他地方(例如,Gill, 2010)也有人认为,商业环境正变得越来越复杂。虽然环境复杂性有许多来源,但一些最重要的驱动因素包括以下几点:全球化:有助于增加参与者的数量、他们的多样性,以及他们之间的相互依赖程度,正如精心设计的全球供应链的出现所证明的那样。…

Nowhere is that challenge more daunting than in business education, where globalization, technological innovation, and increasingly complicated regulations continuously transform the business environment facing graduates and practitioners. Informing science theory proposes that different levels of complexity require different channels if effective informing is to be achieved. The paper first examines how two important sources of complexity--the diversity of clients and the ruggedness of the business landscape--are changing, and how these changes demand vastly more interactive informing channels if impact is to be achieved. Using an exploratory case study methodology, it then takes a detailed look at how one institution--the University of South Florida's Muma College of Business--has introduced a variety of new channels, many of which enable informing flows without necessarily directing them, to adapt to these environmental changes. It then considers both outcomes related to these individual informing channels and college-wide outcomes related to a broad and deep mosaic of informing flows. Finally, it considers the question of the resources required to support these new channels and the relationship between resource acquisition and channel introduction. The proposed framework for looking at business school informing channels can be applied by administrators, faculty members, and key stakeholders in understanding, evaluating, and planning programs and activities supporting informing in a complex environment. Ultimately, the informing business school framework may also provide a means for communicating impact to business school accrediting agencies (such as AACSB).

Recently, however, serious questions are being raised with respect to the impact that higher education is having on its stakeholders (Gill, 2010). In the U.S., high student loan default rates, failure of many students--particularly disadvantaged students--to graduate, the growth in the number of administrators, and the production of expensive research that appears to serve no useful purpose are all symptomatic of these concerns. Nowhere are these concerns more apparent than in today's business schools. Accrediting agencies, such as AACSB International, have made impact a top priority in ongoing accreditations (AACSB, 2008, 2015).

Influence of Information Product Quality on Informing Users: A Web Portal Context 信息产品质量对告知用户的影响:一个门户网站语境

Abstract Web portals have been used as information products to deliver personalized, feature-rich, and flexible information needs to Internet users. However, all portals are not equal. Most of them have relatively a small number of visitors, while a few capture the majority of surfers. This study seeks to uncover the factors that contribute the perceived quality of a general portal. Based on 21 factors derived from an extensive literature review on Information Product Quality (IPQ), web usage, and media use, an experimental study was conducted to identify the factors that are perceived by web portal users as most relevant. The literature categorizes quality factors of an information product in three dimensions: information, physical, and service. This experiment suggests a different clustering of factors: Content relevancy, Communication interactiveness, Information currency, and Instant gratification. The findings in this study will help developers find a more customer-oriented approach to developing high-traffic portals. Keywords: web portal, web portal quality, information quality, information product quality, perceived quality; intention to use Introduction An Information Product can be defined as a highly interdependent package of information that can be digitalized and can be transmitted and distributed in digital form (Fielding et al., 1998; Shapiro & Varian, 1998). Web portals are one of the commonly used Information Products nowadays and an example of the delivery mechanisms in the informing science framework (Cohen, 1999). People often set up a web portal as the first page of their web browser, a single access point to search, retrieve, and disseminate information (Marck, Raving, & Byrd, 2001). This results in the use of web portals for a considerable amount of time every day. To enhance the quality of website design, many developers refer to the templates proposed by software vendors. Most of the design principles were derived from the well-tested UML-based Graphical User Interfaces design principles and the increasing use of flash and related technologies. However, due to the necessity of using the portals as a gateway for collecting data that could be exploited for marketing and marketing research purposes, the design of the portals has recently been more directed toward the needs of the businesses rather than focusing on the desires of the surfers or customers. Google.com has recently issued some quality guidelines to remind developers to "make pages primarily for users, not for search engines" since there is an increasing trend to deceive surfers or present different content to improve search engine rankings ("Webmaster guidelines", 2009). In contrast, there remains little research as to what would attract users to a portal, as a particular Information Product (Meisel & Sullivan, 2000). Since many people spend a significant of their time on the use of web portals every day, it becomes important to investigate how people to use web
Web门户作为一种信息产品,向Internet用户提供个性化、功能丰富、灵活的信息需求。然而,并非所有门户都是平等的。其中大多数都有相对较少的游客,而少数则吸引了大多数冲浪者。本研究旨在揭示影响一般门户感知质量的因素。基于对信息产品质量(IPQ)、网络使用和媒体使用的广泛文献综述得出的21个因素,进行了一项实验研究,以确定门户网站用户认为最相关的因素。文献将信息产品的质量因素分为三个维度:信息、物理和服务。这个实验提出了一个不同的聚类因素:内容相关性、交流互动性、信息流通和即时满足。本研究的发现将帮助开发人员找到一种更面向客户的方法来开发高流量门户。关键词:门户网站,门户质量,信息质量,信息产品质量,感知质量;信息产品可以定义为高度相互依赖的一揽子信息,这些信息可以数字化,并且可以以数字形式传输和分发(Fielding等人,1998;夏皮罗和瓦里安,1998)。门户网站是当今常用的信息产品之一,也是信息科学框架中交付机制的一个例子(Cohen, 1999)。人们经常将门户网站设置为浏览器的第一页,作为搜索、检索和传播信息的单一接入点(mark, Raving, & Byrd, 2001)。这导致每天使用门户网站的时间相当长。为了提高网站设计的质量,许多开发人员参考了软件供应商提出的模板。大多数设计原则来源于经过良好测试的基于uml的图形用户界面设计原则,以及越来越多地使用flash和相关技术。然而,由于有必要将门户用作收集数据的网关,这些数据可以用于营销和营销研究目的,因此门户的设计最近更侧重于业务需求,而不是关注冲浪者或客户的愿望。Google.com最近发布了一些质量指南,提醒开发人员“主要为用户而不是为搜索引擎制作页面”,因为欺骗浏览者或呈现不同内容以提高搜索引擎排名的趋势正在增加(“网站管理员指南”,2009)。相比之下,关于门户网站作为一种特定的信息产品是如何吸引用户的研究仍然很少(Meisel & Sullivan, 2000)。由于许多人每天花费大量时间使用门户网站,因此调查人们如何使用门户网站并感知其质量变得非常重要。在本研究中,资讯产品的品质被检验,看它是否能成为决定网站使用的关键因素。考虑到门户网站的质量,门户网站本身的内容并不是唯一重要的事情。门户网站呈现的形式及其提供的服务也非常重要。每一个信息产品都有三个组成部分:信息、物理和服务组件(Alter, 2002)。在本研究中,门户网站的质量是根据这三个组成部分的信息产品进行检查。门户网站的定义和分类Tatnall(2005)将门户网站定义为“作为访问其他网站的门户”和“从多个来源收集信息并使这些信息可供各种用户使用”以及“提供指南服务,帮助保护用户免受互联网混乱的影响,并引导他们走向最终目标”的网站。…

Warranty of Misinforming as an Option in Product Utilization Process 产品使用过程中可选择的错误信息保证

Abstract The following definition of "option" is given in Wikipedia - "In finance, an option is a contract, which gives the buyer (the owner or holder) the right, but not the obligation, to buy or sell an underlying asset or instrument at a specified strike price on or before a specified date, depending on the form of the option" ("Option," n.d.). Option as a risk management (mitigation) tool is broadly used in finance and trade. At the same time, it introduces asymmetry in the sense that, probabilistically, it limits the level of losses (e.g., the price of the option) and allows for unlimited gains. In the market of sophisticated devices (as smart phones, tablets, etc.), where technologies are rapidly advancing, customers usually do not have the experience to use all features of the device at the time of the purchase. Due to the lack of appropriate expertise, the risk of misinforming, leading to not purchasing the "right" device is high, but given enough time to learn the capabilities of the device and map these to the needs and tasks that device will be used for, could provide the client with substantial long term benefits. Warranty of misinforming is a mechanism that provides the client with the opportunity to explore the device and master its features under limited risk of financial losses. Thus, the warranty of misinforming could be considered as an option - the customers buy it (at a fixed cost) and may gain (theoretically) unlimited benefit by realizing (within the terms of the warranty) that the device can be used to solve a variety of problems not envisaged at the time of purchase. In this study we present the idea of treating the warranty of misinforming as an option in finances and provide examples to illustrate our viewpoint. Keywords: warranty of malfunctioning, warranty of misinforming, options, asymmetry, utility, risk of misinforming. "Trial and error is freedom." (Taleb, 2014, p. 246) Introduction The market of complex and technologically advanced devices is growing quickly, offering many challenges to all involved parties. The major challenge is that many new features are included in the next generation devices and these new devices show up on the market almost on a daily basis. This quick turnaround does not allow the customers to learn how to fully utilize the device's built-in features. Additionally, the smart devices allow an easy extension of their capabilities by adding a variety of on-line applications. All of the above significantly affect the risk of misinforming. Usually, at the time of purchase, the seller is not familiar with the problems/tasks the costumer aims to solve with the device and therefore is not able to provide in depth advice. The customer has to gain experience in using the device and mapping its features to the problems/tasks s/he faces.

“期权”的以下定义在维基百科中给出-“在金融中,期权是一种合同,它赋予买方(所有者或持有人)权利,但不是义务,根据期权的形式,在指定日期或之前以指定的执行价格购买或出售标的资产或工具”(“期权”,无日期)。期权作为一种风险管理(缓解)工具被广泛应用于金融和贸易领域。同时,它引入了不对称,从概率上讲,它限制了损失的水平(例如,期权的价格),并允许无限的收益。在技术快速发展的高端设备市场(如智能手机、平板电脑等)中,客户在购买时通常没有体验到设备的所有功能。由于缺乏适当的专业知识,错误信息的风险很高,导致没有购买“正确”的设备,但给予足够的时间来了解设备的功能,并将这些功能映射到设备将用于的需求和任务,可以为客户提供实质性的长期利益。误报保证是一种在有限的经济损失风险下,为客户提供探索设备和掌握其功能的机会的机制。因此,错误信息的保证可以被视为一种选择-客户购买它(以固定成本),并可能获得(理论上)无限的利益,通过实现(在保修条款内)该设备可用于解决购买时未设想的各种问题。在本研究中,我们提出了将错误信息的保证作为财务选择的想法,并提供示例来说明我们的观点。关键词:故障保修、误报保修、期权、不对称、效用、误报风险。“试错就是自由。”(Taleb, 2014, p. 246)引言复杂和技术先进的设备市场正在迅速增长,为所有相关方提供了许多挑战。主要的挑战是下一代设备中包含了许多新功能,这些新设备几乎每天都会出现在市场上。这种快速周转不允许客户学习如何充分利用设备的内置功能。此外,智能设备允许通过添加各种在线应用程序轻松扩展其功能。所有这些都显著影响了虚假信息的风险。通常,在购买时,卖方并不熟悉客户希望用设备解决的问题/任务,因此无法提供深入的建议。客户必须获得使用设备的经验,并将其功能映射到他/她面临的问题/任务。此外,通常很难意识到新遇到的问题/任务可以通过相同的设备来解决,因为客户在购买时没有意识到这种可能性,当然,他/她没有将这些包含在他/她的购买动机中。这表明,错误信息也可能有一些积极的结果。在早期的研究中,误报的正面效应的选择并没有被强调,绝对值得关注。就这些积极结果而言,买卖双方之间的信息不对称并不是量化错误信息风险的关键因素,而且不能通过改善双方之间的沟通过程来减少信息不对称。此外,即使是客户的培训也不一定能揭示产品的潜在潜力,减少误传。设备对特定客户的全部好处通常是通过试验和错误偶然了解的,并且高度依赖于客户快速采用设备的新技术进步的能力。…

Abstract The all-pervasive Internet has created serious problems, such as Internet overuse, which has triggered considerable debate over its relationship with addiction. To further explore its genetic susceptibilities and alternative explanations for Internet overuse, we proposed and evaluated four hypotheses, each based on existing knowledge of the biological bases of addiction, inattention, novelty-seeking, and harm-avoidance. Four genetic loci including DRD4 VNTR, DRD2 TaqlA, COMT Val158Met and 5-HTTLPR length polymorphisms were screened from seventy-three individuals. Our results showed that the DRD4 4R/4R individuals scored significantly higher than the 2R or 7R carriers in Internet Addiction Test (IAT). The 5-HTTLPR short/short males scored significantly higher in IAT than the long variant carriers. Bayesian analysis showed the most compatible hypothesis with the observed genetic results was based on attention (69.8%), whereas hypotheses based harm-avoidance (21.6%), novelty-seeking (7.8%) and addiction (0.9%) received little support. Our study suggests that carriers of alleles (DRD4 2R and 7R, 5-HTTLPR long) associated with inattentiveness are more likely to experience disrupted patterns and reduced durations of Internet use, protecting them from Internet overuse. Further-more, our study suggests that Internet overuse should be categorized differently from addiction due to the lack of shared genetic contributions. Keywords: Internet overuse; inattentiveness; dopamine receptor D4 gene (DRD4); serotonin transporter gene (5-HTTLPR); Internet Addiction Test Introduction The advent of the Internet age in the last decade provided the world with new landscapes of sociability and access. Lately, the growing role of the Internet, along with other new information technologies (e.g., mobile devices and applications), has become increasingly pervasive and influential in all aspects of our everyday life. With its impersonal method of communication, copious amount of information, and many other unprecedented features, the Internet has reshaped and redefined friendships, businesses, professions, academia, and entertainment. Meanwhile, the omnipresent Internet has created serious social and personal problems, everything from privacy theft (Aimeur & Schonfeld, 2011) and cyberbullying (Tokunaga, 2010) to Internet overuse. Is Internet Overuse a Type of Addiction? Since the term "Internet addiction" was first introduced in 1996 (Young, 1996), there has been considerable debate by both clinicians and academicians over whether it should be diagnosed, studied, and treated the same way as substance addictions such as alcohol, nicotine and drugs (Beard & Wolf, 2001; Campbell, Cumming, & Hughes, 2006; Mitchell, 2000; Murali & George, 2007; Young, 2004). The discussion has become even more contentious after pathological gambling became the first behavioral disorder recognized as a type of addiction by the American Psychiatric Association (2013). The controversy is a
无所不在的互联网带来了严重的问题,如网络过度使用,这引发了关于网络与成瘾关系的激烈争论。为了进一步探索其遗传易感性和对互联网过度使用的替代解释,我们提出并评估了四种假设,每一种假设都基于成瘾、注意力不集中、追求新奇和避免伤害的现有生物学基础。从73个个体中筛选出DRD4 VNTR、DRD2 TaqlA、COMT Val158Met和5-HTTLPR长度多态性4个遗传位点。结果表明,DRD4型4R/4R个体在网络成瘾测试(IAT)中的得分显著高于2R或7R携带者。5-HTTLPR短/矮的男性在IAT上的得分明显高于长变异携带者。贝叶斯分析显示,与观察到的遗传结果最一致的假设是基于注意力(69.8%),而基于伤害避免(21.6%)、寻求新奇(7.8%)和成瘾(0.9%)的假设得到的支持很少。我们的研究表明,携带与注意力不集中相关的等位基因(DRD4 2R和7R,长5-HTTLPR)的人更有可能经历网络模式中断和网络使用时间缩短,从而保护他们免受网络过度使用的影响。此外,我们的研究表明,由于缺乏共同的基因贡献,互联网过度使用应该与成瘾区分开来。关键词:网络过度使用;分心而已;多巴胺受体D4基因;血清素转运基因(5-HTTLPR);在过去十年中,互联网时代的到来为世界提供了社交和访问的新景观。最近,互联网和其他新的信息技术(例如,移动设备和应用程序)的作用越来越大,在我们日常生活的各个方面变得越来越普遍和有影响力。互联网以其非个人的交流方式、丰富的信息和许多其他前所未有的特点,重塑和重新定义了友谊、商业、职业、学术和娱乐。与此同时,无处不在的互联网造成了严重的社会和个人问题,从隐私盗窃(Aimeur & Schonfeld, 2011)和网络欺凌(Tokunaga, 2010)到互联网过度使用。过度使用网络是一种成瘾吗?自从1996年首次提出“网瘾”一词以来(Young, 1996),临床医生和学者们就是否应该像酒精、尼古丁和毒品等物质成瘾一样诊断、研究和治疗网瘾进行了相当大的争论(Beard & Wolf, 2001;坎贝尔,卡明,&休斯,2006;米切尔,2000;Murali & George, 2007;年轻,2004)。在病态赌博成为第一个被美国精神病学协会认定为成瘾类型的行为障碍(2013年)之后,讨论变得更加有争议。争议也反映在术语的使用上。除了网络成瘾,一些人将其称为网络成瘾障碍(Bai, Lin, & Chen, 2001),而另一些人则更喜欢病态网络使用(Morahan-Martin & Schumacher, 2000)或网络依赖(W. Wang, 2001)。在本研究中,互联网过度使用一词被用来涵盖集体现象。尽管存在争论和争议,但互联网过度使用已成为研究的热门话题。1996年至2006年间,发表了120多篇同行评议的关于互联网过度使用及相关主题的文章(byn et al., 2009)。在东亚国家,如中国和韩国,对互联网过度使用的研究最多(Weinstein & Lejoyeux, 2010)。这似乎与该地区互联网过度使用的高发率和与互联网过度使用相关的悲惨事件频发相对应(Choi et al., 2009;邓&轩,2009;Lam, Peng, Mai, & Jing, 2009;Park, Kim, & Cho, 2008;蔡等. ...

To further explore its genetic susceptibilities and alternative explanations for Internet overuse, we proposed and evaluated four hypotheses, each based on existing knowledge of the biological bases of addiction, inattention, novelty-seeking, and harm-avoidance. Four genetic loci including DRD4 VNTR, DRD2 TaqlA, COMT Val158Met and 5-HTTLPR length polymorphisms were screened from seventy-three individuals. Our results showed that the DRD4 4R/4R individuals scored significantly higher than the 2R or 7R carriers in Internet Addiction Test (IAT). The 5-HTTLPR short/short males scored significantly higher in IAT than the long variant carriers. Bayesian analysis showed the most compatible hypothesis with the observed genetic results was based on attention (69.8%), whereas hypotheses based harm-avoidance (21.6%), novelty-seeking (7.8%) and addiction (0.9%) received little support. Our study suggests that carriers of alleles (DRD4 2R and 7R, 5-HTTLPR long) associated with inattentiveness are more likely to experience disrupted patterns and reduced durations of Internet use, protecting them from Internet overuse. Further-more, our study suggests that Internet overuse should be categorized differently from addiction due to the lack of shared genetic contributions. Keywords: Internet overuse; inattentiveness; dopamine receptor D4 gene (DRD4); serotonin transporter gene (5-HTTLPR); Internet Addiction Test Introduction The advent of the Internet age in the last decade provided the world with new landscapes of sociability and access. Lately, the growing role of the Internet, along with other new information technologies (e.g., mobile devices and applications), has become increasingly pervasive and influential in all aspects of our everyday life. With its impersonal method of communication, copious amount of information, and many other unprecedented features, the Internet has reshaped and redefined friendships, businesses, professions, academia, and entertainment. Meanwhile, the omnipresent Internet has created serious social and personal problems, everything from privacy theft (Aimeur & Schonfeld, 2011) and cyberbullying (Tokunaga, 2010) to Internet overuse. Is Internet Overuse a Type of Addiction? Since the term \"Internet addiction\" was first introduced in 1996 (Young, 1996), there has been considerable debate by both clinicians and academicians over whether it should be diagnosed, studied, and treated the same way as substance addictions such as alcohol, nicotine and drugs (Beard & Wolf, 2001; Campbell, Cumming, & Hughes, 2006; Mitchell, 2000; Murali & George, 2007; Young, 2004). The discussion has become even more contentious after pathological gambling became the first behavioral disorder recognized as a type of addiction by the American Psychiatric Association (2013).

Abstract In his "Theses on the Philosophy of History", Walter Benjamin suggests that all cultural treasures "owe their existence not only to the efforts of the great minds and talents who have created them, but also to the anonymous toil of their contemporaries. There is no document of civilization which is not at the same time a document of barbarism". The most obvious and prominent examples of cultural treasures in Benjamin's discourses can be found in monumental architectural works, and history has shown that rulers have really been interested in such splendor stone statements. Benjamin's discourse challenges a dominant idea that seeks to give an ambitious image of these architectural works with the purpose of confirming and endorsing a splendid cultural past so that it can give shape to an integrated and arbitrary cultural geography. This theoretical study, which has been conducted using library resources, employing the discourse and method of "cinematic thinking", attempts to review the role of these monumental architectural works in establishing and shaping national cultural geography. This process is an effort to open boundaries of theorization in area of art and architecture, with the help of ideas that moving cinematic images leave in place. Keywords: cinematic thinking, monumental architectural works, cultural documents, montage, cultural imaginary geography. Introduction Interdisciplinary studies refers to "the process of communication, interaction, and integration of knowledge, concepts, experiences, and specialties of two or several scientific disciplines which is conducted with purpose of comprehensive recognition, dynamic understanding, and scientific analysis of real problems, subjects, and phenomena" (Khorsandi Tasko, 2008, p. 36). Interdisciplinary studies create a space between participating disciplines and focus on overlapping areas between disciplines. In these studies, relations are quite relative, and participating parties can benefit from hypotheses and fundamentals of involved perspectives disciplines proportionately. Interdisciplinary studies, by expanding boundaries of knowledge, enable examination of different phenomena with various perspectives obtained from different disciplines and by opening traditional boundaries of fields to one another, expand potentials of each of participating areas. The more interdisciplinary studies can cross barriers and walls that separate disciplines, the more dynamic and creative interdisciplinary interactions are realized. In order to build a common ground in interdisciplinary studies, the following techniques have been proposed (Repko, Newell, & Szostak, 2011): 1- Redefinition: Semantic explanation & adaptation of terms and hypotheses 2- Extension: Extension of a new idea or territory 3- Organization: Explaining implicit commonalities between areas and describing the commonalities between them 4- Transformation: Observing differences Some theorists believe that in interdisciplinary stu
沃尔特·本雅明在《历史哲学提纲》中指出,一切文化瑰宝的存在“不仅要归功于创造它们的伟大思想家和人才的努力,也要归功于同时代人的默默无闻的辛勤劳动”。没有一份文明的文件不是同时也是一份野蛮的文件”。本雅明话语中最明显、最突出的文化宝藏可以在不朽的建筑作品中找到,历史表明,统治者确实对这种辉煌的石头宣言感兴趣。本雅明的话语挑战了一种主流观念,即试图给这些建筑作品一个雄心勃勃的形象,目的是确认和认可一个辉煌的文化过去,这样它就可以塑造一个完整的、任意的文化地理。本理论研究利用图书馆资源,运用“电影思维”的话语和方法,试图回顾这些纪念性建筑作品在建立和塑造国家文化地理中的作用。这个过程是一个努力,在艺术和建筑领域的理论化的边界,与思想的帮助下,移动的电影图像留下的地方。关键词:电影思维,纪念性建筑作品,文化文献,蒙太奇,文化想象地理。跨学科研究是指“以全面认识、动态理解和科学分析实际问题、主题和现象为目的,将两个或多个科学学科的知识、概念、经验和专长进行交流、互动和整合的过程”(Khorsandi Tasko, 2008, p. 36)。跨学科研究在参与的学科之间创造了一个空间,并关注学科之间的重叠领域。在这些研究中,关系是相对的,参与方可以按比例地从所涉及的观点学科的假设和基础中获益。跨学科研究,通过扩大知识边界,从不同学科获得不同的观点来检查不同的现象,通过开放传统的领域边界,扩大每个参与领域的潜力。跨学科研究越能跨越学科之间的障碍和壁垒,跨学科的互动就越有活力和创造性。为了在跨学科研究中建立一个共同点,提出了以下技术(Repko, Newell, & Szostak, 2011): 1-重新定义:术语和假设的语义解释和适应2-扩展:新思想或领域的扩展3-组织:解释领域之间的隐含共性并描述它们之间的共性4-转换:一些理论家认为,在跨学科研究中,各个学科的边界和领域保持不变,在相邻和联谊的过程中,各个参与学科保持各自的独立性。另一组认为,跨学科方法可以挑战相关分支的初始假设,并且作为学科之间合作和参与的结果,新的假设可能在每个学科中出现。这是信息科学研究所提出的立场。因此,跨学科方法通过揭示沉默和隐藏的方面,可以跨越和违反严格的格式和既定的边界(Khorsandi Tasko, 2008)。根据Klein的说法,通过跨学科研究的延伸,“将知识作为基础或线性结构的处理已经被网络和网络等术语所取代”(引自Khorshidi & Pishgahi, 2012, p. ...)
