Exploring Chaotic Performance in Projects and its Relationship with Knowledge Creation Process 探索项目中的混沌绩效及其与知识创造过程的关系
R. A. Samra, K. Shaalan
In this study the researcher is focusing on the performance of the project. During the life cycle of projects managers are striving to forecast the future performance of the project according to the historical patterns of performance. Irregular performance and randomness are representing chaotic performance periods in project's life. The study proposes five propositions. The first proposition is that Manager have different conscious perceptions about accepted levels of order and chaos in their project performance. The second proposition is that Knowledge Creation Process has different characteristics in chaotic perceived projects and order perceived projects. The third proposition is that managers have different prioritization of knowledge assets from which they create new knowledge for chaotic performance projects. The fourth proposition is that Sources of knowledge creation differ according to the context of project performance. The fifth proposition is that Assets used for knowledge creation during chaotic performance periods differ according to managers' tendency to innovate. This study is a qualitative analysis of secondary data that comes from literature review and primary data that comes from interviews with experts and project managers. The researcher investigated four styles of knowledge creation during chaotic performance periods; experiential knowledge creation style, innovative knowledge creation style, precautions and risk minimization knowledge creation style, and specialty based knowledge creation style. Conclusions and recommendations are provided to project managers on which knowledge assets are leading to innovative knowledge creation.
在本研究中,研究人员关注的是项目的绩效。在项目生命周期中,项目经理努力根据项目的历史绩效模式来预测项目的未来绩效。不规则性能和随机性代表了项目生命周期的混沌性能阶段。该研究提出了五个主张。第一个命题是,经理对项目绩效中可接受的有序和混乱程度有不同的意识感知。第二个命题是知识创造过程在混沌感知项目和有序感知项目中具有不同的特征。第三个命题是,管理者对知识资产有不同的优先级,他们从这些资产中为混乱的绩效项目创造新的知识。第四个命题是,知识创造的来源根据项目绩效的背景而不同。第五个命题是,在混乱绩效时期,用于知识创造的资产根据管理者的创新倾向而有所不同。本研究是对来自文献综述的次要数据和来自专家和项目经理访谈的主要数据的定性分析。研究了企业在混乱绩效期的四种知识创造模式;体验型知识创造模式、创新型知识创造模式、防范与风险最小化型知识创造模式、专业型知识创造模式。结论和建议提供给项目经理的知识资产是导致创新的知识创造。

The Impact of Corporate Social Responsibility on the Firm's Financial Performance: the case of Publicly Listed Companies in the United Arab Emirates 企业社会责任对企业财务绩效的影响:以阿联酋上市公司为例
Sahar Mansour, Ali Mahdi Owayid, M. Ramadan
CSR in UAE still acknowledged as a new topic, the relationship between corporate social responsibility (CSR) and the firm's financial performance (FP) is important topic for researchers. The primary aim of the research is to develop a new conceptual framework that will address the underlying relationships between CSR and FP in the publicly listed companies in the UAE. The interaction effects between the CSR practices and FPof the UAE's firm will be studied by responding to the main research question by way of a triangulation of research data within a mixed-method research paradigm that integrates both quantitative and qualitative methodology. The result of analysis should confirm the association between CSR practices and firms FP in UAE. The results will also highlight whether a "Knowledge Gap" exists between the academic (theoretical) and the practical (applied) domains.

Creating incentives for knowledge sharing: combining context and signaling 为知识共享创造激励:结合语境和信号
Jouni A. Laitinen, D. Senoo
Incentives to encourage knowledge sharing have received considerable attention from the research community. However, consensus on the influence of incentives on sharing levels and what are the critical success factors is yet to emerge. This causes challenges for both knowledge management researchers and practitioners, as the effects of incentive systems cannot be predicted consistently. Hence, this article aims to discuss the critical factors for creating incentive systems to encourage sharing. To improve the prediction accuracy for such systems, a new framework is proposed. The proposed framework is a combination of sociological and economical approaches, which covers both the influence incentives and the relational factors that govern the behaviour of individuals in any given relationship. Analysis of a case study base on the proposed framework is then compared to two alternative frameworks approaches to incentive design. The comparison between the predictions made by the three theories shows that the prediction power and that the critical factors for designing incentives varies significantly. Therefore, when managers design new incentive structures to encourage knowledge sharing, they need to consider which theory captures their hidden assumptions and the presented situation's foundations most accurately. Finally future research directions are suggested based on the predictions made with the framework are proposed.
鼓励知识共享的激励措施受到了研究界的广泛关注。然而,关于激励措施对分享水平的影响以及什么是关键的成功因素,尚未达成共识。这给知识管理研究者和实践者都带来了挑战,因为激励制度的效果无法一致地预测。因此,本文旨在讨论创建激励机制以鼓励共享的关键因素。为了提高这类系统的预测精度,提出了一种新的预测框架。拟议的框架是社会学和经济学方法的结合,涵盖了影响激励和在任何特定关系中支配个人行为的关系因素。然后,将基于提议框架的案例研究分析与激励设计的两种替代框架方法进行比较。三种理论的预测结果对比表明,预测能力和激励设计的关键因素存在显著差异。因此,当管理者设计新的激励结构以鼓励知识共享时,他们需要考虑哪一种理论最准确地捕捉了他们隐藏的假设和所呈现的情况的基础。最后,在此基础上提出了未来的研究方向。

Learning Enterprise Resource Planning (ERP) through Business Simulation Game 通过商业模拟游戏学习企业资源规划(ERP)
Paul Wu Horng-Jyh
Ever since its inception in the 1980s, Enterprise Resource Planning (ERP) has been readily making inroads into enterprise computing, became the focus of innovation, replacing traditional functional Management Information Systems, and finally established itself as the main stream of enterprise computing [1]. Nowadays every enterprises run ERP systems of some sort. ERP systems are also the backbone of Business Intelligence as well as Supply Chain Management (SCM) and Customer Relationship Management (CRM) systems. In this workshop, we shall focus on learning 2 key concepts of ERP: (1) Business Processes Integration that integrates Business Functions across Business Units (2) Managing supply to meet demand. How to make these two key concepts come alive for participants learning ERP is critical especially if they do not have business background. We design a learning activity system that is inspired by SECI [2] and Cascading Modes of Communication (CMC) knowledge creation theory [3, 4 & 5]. An ERP business simulation game1 is deployed as Socialization space to engender experiential knowledge about ERP among its participants. These experiences became the basis on which, the participants Externalize what they learnt about key ERP concepts, which is shared among team members and the entire group of participants with the objective to engender Combination of knowledge into a structured game plan. Finally, the game plan is to be Internalized through another round of the game play, that in turn, fosters a new round of knowledge creation cycle.
企业资源规划(Enterprise Resource Planning, ERP)自20世纪80年代诞生以来,迅速进入企业计算领域,成为创新的焦点,取代了传统的功能管理信息系统,最终成为企业计算的主流[1]。如今,每个企业都在运行某种类型的ERP系统。ERP系统也是商业智能、供应链管理(SCM)和客户关系管理(CRM)系统的支柱。在本次研讨会中,我们将重点学习ERP的两个关键概念:(1)业务流程集成,集成跨业务单元的业务功能(2)管理供应以满足需求。对于学习ERP的参与者来说,如何使这两个关键概念生动起来是至关重要的,特别是如果他们没有商业背景的话。我们设计了一个学习活动系统,该系统受到SECI[2]和级联通信模式(CMC)知识创造理论[3,4,5]的启发。将ERP业务模拟游戏1作为社会化空间,在参与者之间产生ERP经验知识。这些经验成为基础,在此基础上,参与者外化他们所学到的ERP关键概念,这些概念在团队成员和整个参与者群体中共享,目的是将知识组合成结构化的游戏计划。最后,游戏计划将通过另一轮的游戏被内化,这反过来又促进了新一轮的知识创造循环。

Jonnathan Acosta, Michael Gregory, Adriana Marcela Vega Escobar, Álvaro Espinel Ortega
This paper presents the design and development of an energy system for residences, destined for the consumer to do knowledge management through supervision and control electrical household and contribute to the rational use of energy, using protocols of OSI model (Open System Interconnection)[1] such as: Power Line Communication (PLC) [2], Ethernet, TCP-UDP/IP (Transport Control Protocol -- User Datagram Protocol/Internet protocol) and high level protocol HTTP (Hipertext Protocol) [3]. The system, from the hardware's perspective, is based on the use of ARM Cortex M4 of Freescale® microcontroller referenced as MK10 [4] and a system for voltage, current, power factor and energy measurement through Analog Device's® [5] ADE7763® device. A web application will be installed on the microcontroller so it can be used from any tablet or smartphone through Wi-Fi protocol, which allows to develop measurement and storage tasks on a data base, in the same way as turning on and off devices to be controlled, allowing the consumer to do knowledge management and perform energy saving in the residence.

IMR based Anonymization for Privacy Preservation in Data Mining 基于IMR的数据挖掘中隐私保护的匿名化
G. Arumugam, V. J. V. Sulekha
Privacy Preserving Data Mining (PPDM) is a data mining research area that aims to protect individual's personal information from unsolicited or unauthorized disclosure. Privacy relates to personal information that a person would not wish others to know without authorization, and to a person's right to be free from the attention of others (UN Declaration of Human Rights, 1948). Advances in computer technology, social networking sites, communications and improvement in hardware technologies have made it possible to collect and store huge amounts of data in digital form. This results in the increasing ability to collect large amounts of personal information. However the collection and sharing of data have also raised a number of ethical issues. Such issues include privacy, data security, and intellectual property rights. These Privacy Issues violates a person's right and brings dignitary harm to the research participant. In addition, it would also bring social mortification, shame, disgrace, and damage to social and economic status. In recent years, numerous data mining algorithms combining privacy preserving techniques have been developed that hide sensitive item sets or patterns. An important issue here is to decide which privacy preserving technique gives better protection for sensitive information. It is also important to access the quality of the result as well as the performance of the algorithm, after applying the privacy preserving techniques. In this paper, we propose IMR (I - Buckets based Map Reducing) based Anonymization and present a brief introduction of different kinds of PPDM techniques with their merits and demerits. Our work highlights some considerations about future work and promising directions in the perspective of privacy preservation in data mining.
隐私保护数据挖掘(PPDM)是一个数据挖掘研究领域,旨在保护个人信息免受未经请求或未经授权的披露。隐私指的是一个人在未经授权的情况下不希望别人知道的个人信息,以及一个人不受他人注意的权利(联合国人权宣言,1948年)。计算机技术、社交网站、通信和硬件技术的进步使得以数字形式收集和存储大量数据成为可能。这导致收集大量个人信息的能力不断增强。然而,数据的收集和共享也引发了一些伦理问题。这些问题包括隐私、数据安全和知识产权。这些隐私问题侵犯了个人权利,给研究参与者带来尊严损害。此外,它还会给社会带来屈辱、耻辱、耻辱,损害社会经济地位。近年来,许多结合隐私保护技术的数据挖掘算法被开发出来,以隐藏敏感的项目集或模式。这里的一个重要问题是确定哪种隐私保护技术可以更好地保护敏感信息。在应用隐私保护技术之后,访问结果的质量以及算法的性能也很重要。在本文中,我们提出了基于IMR (I - Buckets - based Map reduction)的匿名化,并简要介绍了各种PPDM技术的优缺点。我们的工作强调了对数据挖掘中隐私保护的未来工作和有希望的方向的一些考虑。

Influence of News on Individual Confidence Bias in Stock Markets 新闻对股票市场个人信心偏差的影响
Y. R. Mukund, V. Naresh, Sourabh Patil, K. Chandrasekaran, V. Kumar, R. K. Gnanamurthy
The Phenomenon of stock markets is a complex one and is something which, has attracted researchers and statisticians for a long time. Complex statistics have long dominated this field where the prediction models are usually stochastic. The advent of machine learning gave us a new way of looking at the problem. Much work has been done in analyzing the stock market to predict the stock index of a particular organization. However, most of the work done is based on the previous stock data and other statistical parameters. Our work, uses data such as the online news articles about a particular company and aims to help a trader conclude the market sentiment towards that company through sentiment analysis. The online raw data is obtained through crawling and is indexed, weighted and subject to sentiment analysis to output the final sentiment of the market. It is found that the Naive-Bayesian Classifier is the more suitable option among the Decision Tree and Random Forests for the task of sentiment analysis. The Final Sentiment Factor arrived at, is found to reflect the real time market sentiment quite accurately. It is also shown that the sentiment factor can be used as an input to a more complex analysis model. This new model, performs better than the existing models.
股票市场现象是一个复杂的现象,长期以来一直是研究人员和统计学家关注的问题。复杂统计长期以来一直主导着这一领域,而预测模型通常是随机的。机器学习的出现给我们提供了一种看待问题的新方法。在分析股票市场以预测特定组织的股票指数方面已经做了很多工作。然而,所做的大部分工作都是基于以前的股票数据和其他统计参数。我们的工作,使用数据,如在线新闻文章,关于一个特定的公司,旨在帮助交易者得出结论,市场对该公司的情绪通过情绪分析。通过抓取获取在线原始数据,并对其进行索引、加权和情绪分析,输出最终的市场情绪。研究发现,在决策树和随机森林中,朴素贝叶斯分类器更适合于情感分析任务。最终情绪因子的到达,被发现是相当准确地反映了实时市场情绪。研究还表明,情绪因素可以作为更复杂的分析模型的输入。这种新型号比现有型号性能更好。

The online raw data is obtained through crawling and is indexed, weighted and subject to sentiment analysis to output the final sentiment of the market. It is found that the Naive-Bayesian Classifier is the more suitable option among the Decision Tree and Random Forests for the task of sentiment analysis. The Final Sentiment Factor arrived at, is found to reflect the real time market sentiment quite accurately. It is also shown that the sentiment factor can be used as an input to a more complex analysis model. This new model, performs better than the existing models.","PeriodicalId":159180,"journal":{"name":"Proceedings of the The 11th International Knowledge Management in Organizations Conference on The changing face of Knowledge Management Impacting Society","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133505361","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}

M. Thangaraj, P. P. Ponmalar, G. Sujatha, S. Anuradha
Internet of Things (IoT) is to connect objects of different application fields, functionality and technology. These objects are entirely addressable and use standard communication protocol. Intelligent agents are used to integrate Internet of Things with heterogeneous low-power embedded resource-constrained networked devices. This paper discusses with the implemented real world scenario of smart autonomous patient management with the assistance of semantic technology in IoT. It uses the Smart Semantic framework using domain ontologies to encapsulate the processed information from sensor networks. This embedded Agent based Semantic Internet of Things in healthcare (ASIOTH) system is having semantic logic and semantic value based Information to make the system as smart and intelligent. This paper aims at explaining in detail the technology drivers behind the IoT and health care with the information on data modeling, data mapping of existing IoT data into different other associated system data, workflow or the process flow behind the technical operations of the remote device coordination, the architecture of network, middleware, databases, application services. The challenges and the associated solution in this field are discussed with the use case.
