More and more IT organizations or IT outsourcing service providers are embracing Information Technology Process Automation (ITPA) as it has transformed the way IT services are delivered to end users. As a result, one of the highly claimed benefits of ITPA is total cost reduction in IT operations. However, ITPA subjects to different interpretations on topics like ITPA criteria, use cases as well as its effects on organizations. Today, there is limited literature and conflicting views on such ITPA topics. The objective of this study is to shed some lights on ITPA criteria, use cases as well as the effects ITPA brings. The effects include the benefits as well as negative effects of ITPA. Moreover, some factors to guide organizations how to adopt and deploy ITPA are also discussed. This study has taken a qualitative approach in which ITPA literature was reviewed and some IT professionals were interviewed. Lastly, limitations of the study, future research and conclusion were also provided.
越来越多的IT组织或IT外包服务提供商正在接受信息技术过程自动化(ITPA),因为它已经改变了向最终用户交付IT服务的方式。因此,ITPA的一大好处就是降低了IT运营的总成本。然而,ITPA在诸如ITPA标准、用例及其对组织的影响等主题上有不同的解释。目前,关于此类ITPA主题的文献有限,观点相互矛盾。本研究的目的是阐明ITPA标准、用例以及ITPA带来的影响。其影响既有有利的一面,也有不利的一面。此外,还讨论了指导组织如何采用和部署ITPA的一些因素。本研究采用定性方法,对ITPA文献进行了回顾,并对一些IT专业人员进行了访谈。最后,对研究的局限性、未来的研究方向和结论进行了展望。

Many authors have studied the influence exerted by tourism on the economy. Today, Information and Communication Technologies (ICT) are an important factor influencing competitiveness in the tourism sector and consumers’ decision-making concerning tourism purchases. Along with the expansion of the European Union, the revolution in passenger air transportation has spread over new member states in Central and Eastern Europe, including Poland. The authors of this study analyzed ticket prices on Internet websites that aggregate offers from different carriers and on the websites managed by the carriers themselves, specifically studying offers for the most popular flight connections from F. Chopin airport in Warsaw to London, Frankfurt, Munich, and Paris. For each connection, the study examined flights operated by the Polish carrier, i.e., LOT Polish Airlines, and by a carrier originating from a destination country. The analysis of the particular coefficients illustrating the price dispersion for each flight operated by a foreign carrier in comparison to the offer from LOT Polish Airlines points to the conclusion that the tickets offered by the latter were marked by a much narrower price dispersion in contrast to the connections offered by foreign carriers on the same route.
许多作者研究了旅游业对经济的影响。如今,信息和通信技术(ICT)是影响旅游部门竞争力和消费者旅游购买决策的重要因素。随着欧盟的扩大,客运航空运输的革命已经蔓延到包括波兰在内的中欧和东欧的新成员国。这项研究的作者分析了互联网网站上的机票价格,这些网站汇总了来自不同航空公司的报价,以及航空公司自己管理的网站,特别研究了从华沙F. Chopin机场到伦敦、法兰克福、慕尼黑和巴黎的最受欢迎的航班报价。对于每个连接,研究检查了波兰航空公司(即LOT波兰航空公司)运营的航班,以及从目的地国家出发的航空公司运营的航班。对说明外国航空公司经营的每个航班与波兰航空公司提供的机票价格差异的特定系数的分析指出,与外国航空公司在同一航线上提供的连接相比,波兰航空公司提供的机票价格差异要小得多。

Platform Integration and Demand Spillovers in Complementary Markets: Evidence from Facebook’s Integration of Instagram 互补市场中的平台整合与需求溢出:来自Facebook整合Instagram的证据

Social media platform owners often choose to provide tighter integration with their own complementary applications (i.e., first-party applications) as compared to that with other complementary third-party applications. We study the impact of such integration on consumer demand for first-party applications and competing third-party applications by exploring Facebook’s integration of Instagram in its photo-sharing application ecosystem. We find that consumers obtain additional value from Instagram after its integration with Facebook, leading to a large increase in the use of Instagram for Facebook photo-sharing. Further, we find that the growth of Instagram’s user base has a positive spillover effect on big third-party applications and a negative spillover effect on small third-party applications in Facebook’s photo-sharing ecosystem. As a result, while small third-party applications face reduced demand post-integration, big third-party applications experience a small increase in demand due to Facebook’s integration of Instagram. Thus, the overall demand for the entire photo-sharing application ecosystem actually increases, which suggests that Facebook’s integration strategy benefits the complementary market overall. Our results highlight the role of platform integration for first-party applications and the application ecosystem overall, and have implications for strategic management of first-party applications in the presence of third-party applications.
与其他互补的第三方应用程序相比,社交媒体平台所有者通常选择与自己的互补应用程序(即第一方应用程序)提供更紧密的集成。我们通过探索Facebook在其照片分享应用生态系统中整合Instagram的情况,研究了这种整合对消费者对第一方应用和竞争第三方应用需求的影响。我们发现,在Instagram与Facebook整合后,消费者从Instagram中获得了额外的价值,导致Instagram在Facebook上分享照片的使用大幅增加。此外,我们发现Instagram用户群的增长对Facebook照片分享生态系统中的大型第三方应用具有正向溢出效应,而对小型第三方应用具有负向溢出效应。因此,小型第三方应用在整合后需求减少,而大型第三方应用在Facebook整合Instagram后需求小幅增加。因此,对整个照片分享应用生态系统的总体需求实际上是增加的,这表明Facebook的整合战略总体上有利于互补市场。我们的研究结果强调了平台集成对第一方应用程序和整个应用生态系统的作用,并对存在第三方应用程序的第一方应用程序的战略管理具有启示意义。

The Interaction of Signals: A Fuzzy Set Analysis of the Video Game Industry 信号的相互作用:电子游戏产业的模糊集分析
Pub Date : 2014-06-01 DOI: 10.2139/ssrn.2456991

Customers continuously evaluate the credibility and reliability of a range of signals both separately and jointly. However, existing econometric studies pay insufficient attention to the interactions and complex combinations of these signals, and are typically limited as a result of difficulties controlling for multicollinearity and endogeneity in their data. We develop a novel theoretical approach to address these issues and study different signaling effects (i.e., word-of-mouth, brand reputation, and distribution strategy) on customer perceptions. Using data on the US video games market, we apply a fuzzy set qualitative comparative analysis (fsQCA) to account for cause-effect relationships. The results of our study address a number of key issues in the economics and management literature. First, our results support the contention that reviews from professional critics act as a signal of product quality and therefore positively influence unit sales, as do the discriminatory effects of prices and restricted age ratings. Second, we find evidence to support the use of brand extension strategies as marketing tools that create spillover effects and support the launch of new products.
客户不断地评估一系列信号的可信度和可靠性,无论是单独的还是联合的。然而,现有的计量经济学研究对这些信号的相互作用和复杂组合关注不足,并且由于难以控制其数据中的多重共线性和内生性,通常受到限制。我们开发了一种新的理论方法来解决这些问题,并研究了不同的信号效应(即口碑,品牌声誉和分销策略)对客户感知的影响。使用美国视频游戏市场的数据,我们应用模糊集定性比较分析(fsQCA)来解释因果关系。我们的研究结果解决了经济学和管理学文献中的一些关键问题。首先,我们的结果支持这样的论点,即专业评论家的评论作为产品质量的信号,因此对单位销售产生积极影响,价格和限制年龄评级的歧视性影响也是如此。其次,我们找到证据支持使用品牌延伸策略作为营销工具,创造溢出效应和支持新产品的推出。

textabstractThis paper presents the findings of a longitudinal study of a large corporation's transition to a new business model in the face of a major transformation in the ICT industry brought about by Cloud computing. We build theory on the process of business model innovation through a qualitative study that investigates how an established firm organizes for an emerging business model. Contrary to previous findings that presented spatial separation as the optimal structural approach for dealing with two competing business models, our findings indicate a need for recursive iterations between different modes of separated and integrated structures in line with the emergent nature of strategic intent toward the new business models. Our analyses reveal strategy formation to be a collective experimental learning process revolving around a number of alternative strategic intentions ranging from incremental evolution and transformation to complete replacement of the existing business model. Given the fundamental differences in the nature and requirements of those alternative intents, iterations between different structural modes and differing combinations proved to be crucial in enabling the organization to make transition to the new business model.
本文介绍了一项纵向研究的结果,该研究针对一家大公司在面对云计算带来的ICT行业重大变革时向新商业模式的过渡进行了研究。我们通过一项定性研究来建立商业模式创新过程的理论,该研究调查了一个成熟的公司如何为新兴的商业模式组织起来。与先前的研究结果相反,空间分离是处理两种竞争商业模式的最佳结构方法,我们的研究结果表明,根据对新商业模式的战略意图的突发性,需要在分离和集成结构的不同模式之间进行递归迭代。我们的分析表明,战略形成是一个集体的实验性学习过程,围绕着许多可选的战略意图,从渐进式发展和转型到完全取代现有的商业模式。考虑到这些可选意图的本质和需求的根本差异,不同结构模式和不同组合之间的迭代被证明是使组织能够过渡到新的业务模型的关键。

Do Google Trend Data Contain More Predictability than Price Returns? 谷歌趋势数据比价格回报更具可预测性吗?
Pub Date : 2014-03-07 DOI: 10.2139/ssrn.2405804
D. Challet, Ahmed Bel Hadj Ayed
Using non-linear machine learning methods and a proper backtest procedure, we critically examine the claim that Google Trends can predict future price returns. We first review the many potential biases that may influence backtests with this kind of data positively, the choice of keywords being by far the greatest culprit. We then argue that the real question is whether such data contain more predictability than price returns themselves: our backtest yields a performance of about 17bps per week which only weakly depends on the kind of data on which predictors are based, i.e. either past price returns or Google Trends data, or both.
使用非线性机器学习方法和适当的回测程序,我们批判性地检验了谷歌趋势可以预测未来价格回报的说法。我们首先回顾了许多可能对这类数据的回测产生积极影响的潜在偏差,其中关键词的选择是迄今为止最大的罪魁祸首。然后我们认为,真正的问题是这些数据是否比价格回报本身包含更多的可预测性:我们的回测每周产生约17个基点的表现,这只弱依赖于预测者所基于的数据类型,即过去的价格回报或谷歌趋势数据,或两者兼而有之。

Toward a Social Ontology for Conceptual Modeling 面向概念建模的社会本体
Pub Date : 2014-02-06 DOI: 10.17705/1cais.03470
S. March, G. Allen
Conceptual modeling is fundamental to information systems requirements engineering. Systems analysts and designers use the constructs and methods of a conceptual modeling formalism to represent, communicate and validate the contents, capabilities and constraints of an envisioned information system within its organizational context. The value of such a representation is measured by the degree to which it facilitates a shared understanding among all stakeholders of (1) the organizational information requirements and (2) the ability of the envisioned information system to meet them (Wand and Weber 2002). We propose using the social ontology developed by John Searle (1995, 2006, 2010) as the basis for conceptual modeling and present a meta model based on that ontology.
概念建模是信息系统需求工程的基础。系统分析员和设计者使用概念建模形式化的构造和方法来表示、交流和验证在其组织环境中所设想的信息系统的内容、能力和约束。这种表述的价值是通过它在多大程度上促进了所有利益相关者对(1)组织信息需求和(2)设想的信息系统满足这些需求的能力的共同理解来衡量的(Wand and Weber 2002)。我们建议使用John Searle(1995,2006,2010)提出的社会本体论作为概念建模的基础,并基于该本体论提出元模型。

Prospects for Online Crowdsourcing of Social Science Research Tasks: A Case Study Using Amazon Mechanical Turk 社会科学研究任务在线众包的前景:以亚马逊土耳其机器人为例
Pub Date : 2014-01-09 DOI: 10.2139/SSRN.2377016
Catherine E. Schmitt-Sands, Richard J. Smith
While the internet has created new opportunities for research, managing the increased complexity of relationships and knowledge also creates challenges. Amazon.com has a Mechanical Turk service that allows people to crowdsource simple tasks for a nominal fee. The online workers may be anywhere in North America or India and range in ability. Social science researchers are only beginning to use this service. While researchers have used crowdsourcing to find research subjects or classify texts, we used Mechanical Turk to conduct a policy scan of local government websites. This article describes the process used to train and ensure quality of the policy scan. It also examines choices in the context of research ethics.
虽然互联网为研究创造了新的机会,但管理日益复杂的关系和知识也带来了挑战。亚马逊(Amazon.com)有一项土耳其机器人服务,允许人们以象征性的费用将简单的任务众包。在线工作者可能在北美或印度的任何地方,能力不一。社会科学研究人员才刚刚开始使用这项服务。虽然研究人员使用众包来寻找研究对象或分类文本,但我们使用土耳其机械来对地方政府网站进行政策扫描。本文描述了用于训练和确保策略扫描质量的过程。它还考察了研究伦理背景下的选择。

Publisher's Announcements and Piracy-Monitoring Devices in Software Adoption 软件采用中的发行商公告和盗版监控设备
Pub Date : 2013-11-19 DOI: 10.2139/ssrn.2411447
Eric Darmon, Alexandra Rufini, Dominique Torre
In this paper, we investigate the distribution strategy of a software publisher. The user adoption context is characterized by uncertainty about quality (experience good) and heterogeneous piracy costs. Users can purchase or get unauthorized/illegal copies (digital piracy) of the software during two periods (or not adopt at all). Between these two periods, users can acquire information through word-of-mouth. To maximize profit, the publisher needs to decide about price, quality and level of monitoring of piracy. We show that the software publisher can profit from accommodation a certain level of piracy of the product. We add to the literature by explicitly considering the opportunity for the publisher to cheat about future price and monitoring levels (misleading announcements). This strategy that is falsely permissive towards piracy, can sometimes appear more profitable. However, when the degree of sophistication of user expectations about the publisher's strategy increases, only a strategy that is permissive (with respect to piracy) with non misleading announcements remains robust.
本文研究了一家软件发行商的发行策略。用户采用环境的特点是质量(良好的体验)和异构盗版成本的不确定性。用户可以在两个期间内购买或获得未经授权/非法的软件副本(数字盗版)(或者根本不采用)。在这两个时期之间,用户可以通过口碑获取信息。为了实现利润最大化,发行商需要决定价格、质量和盗版监控水平。我们表明,软件发行商可以从容忍一定程度的盗版产品中获利。我们通过明确考虑出版商在未来价格和监控水平(误导性公告)上作弊的机会来添加文献。这种错误地纵容盗版的策略有时似乎更有利可图。然而,当用户对发行商策略的期望越来越高时,只有允许(针对盗版)且没有误导性声明的策略才能保持稳健。

However, when the degree of sophistication of user expectations about the publisher's strategy increases, only a strategy that is permissive (with respect to piracy) with non misleading announcements remains robust.","PeriodicalId":414091,"journal":{"name":"Innovation & Management Science eJournal","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116250272","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}

This research draws on transaction-cost and resource-based theory to examine how information technology (IT) capital moderates the relationship between different types of assets and firm scope — both vertical integration and diversification. The analysis suggests that IT capital enables firms with narrowly valuable assets to be less vertically integrated and less diversified, and enables firms with broadly valuable assets to be more vertically integrated and more diversified. The moderating influence of IT capital on the relationship between different types of assets and firms’ vertical and product market scope is consistent with transactions-cost as well as resource-based traditions.
本研究利用交易成本和资源基础理论来考察信息技术(IT)资本如何调节不同类型资产和企业范围之间的关系——包括垂直整合和多元化。分析表明,IT资本使具有狭义有价值资产的企业更少垂直整合和更少多元化,并使具有广义有价值资产的企业更垂直整合和更多元化。信息技术资本对不同类型资产与企业垂直和产品市场范围之间关系的调节作用与交易成本和资源基础传统一致。
