Preparing a Data Scientist: A Pedagogic Experience in Designing a Big Data Analytics Course          下载免费PDF全文

In this article, we present an experiential perspective on how a big data analytics course was designed and delivered to students at a major Midwestern university. In reference to the MSIS 2006 Model Curriculum, we designed this course as a level 2 course, with prerequisites in databases, computer programming, statistics, and data mining. Students in the class were mostly seniors or at the graduate level, and had a strong technical and quantitative background. We include details of concepts covered in the course, as well as summaries of four major sample course assignments used. Some of the concepts covered include large‐scale data collection and management using the Hadoop ecosystem, stream mining, visual analytics, and social network analytics. Besides Hadoop, the course also introduced various IBM and Teradata big data tools. We show how the course modules align with the intended learning goals and course objectives. A post‐course survey indicated that the structure and organization of the course helped students clearly and concisely assimilate the course content.  相似文献   

FRP材料在桥梁工程中的应用前景展望     

Amir Mirmiran  张金强 《石家庄铁路职业技术学院学报》2003,2(3):77-80

用以延长普通钢筋混凝土构件使用寿命的腐蚀控制措施不断失效,使人们对纤维增强聚合物(简称FRP)在既有结构的修补和修复,以及新建结构中的应用研究产生了极大兴趣.FRP材料的优点有抗电化学腐蚀性、高比强度、电绝缘性.现将对FRP材料在土木工程中的应用进程进行回顾,对FRP的应用前景作以前瞻,并将讨论FRP用于既有结构的修补.同时,还将介绍FRP应用于新建结构中,即作为原始承载构件、作为普通筋或者预应力筋用于混凝土构件中、作为混凝土的成型模板等几种应用型式.  相似文献

Triggering effects of mobile video marketing in nature tourism: Media richness perspective     

Ari Alamäki  Juho Pesonen  Amir Dirin 《Information processing & management》2019,56(3):756-770

The aim of this study was to investigate videos as potential triggers of behavior. Therefore, we applied the theories of triggers and media richness to learn about the triggering efficiency of mobile marketing videos on participants’ behavioral intentions. The experiment involved three distinct test groups, each comprising 41 student participants. From the perspective of media richness theory, we observed that the different kinds of videos had quite similar effects in terms of triggering behavioral changes. However, the mechanisms explaining why triggers were present differed for each video. Further, the results reveal that the consumer's position in the information search process was the most significant reason for the triggering of any kind of effect. In addition, the instructionally designed videos were able to exert an affective triggering effect: the more participants liked the video, the more it affected their participation intention and recall scores. This study extends the media richness research by demonstrating that the effects of media richness can vary within technically similar videos, as they form different logical connections among non-verbal visual cues related to a video's storyline.  相似文献

Linear-constant log-map,a fast accurate algorithm for map decoding     

Hamid Samadian  Amir Mousavie Nia 《Journal of The Franklin Institute》2012,349(5):1721-1733

This paper proposes a new approximation to be used for the correction function in the turbo decoding algorithm, called Linear-Constant-log Map. Max-log Map, Linear-log Map and Constant-log Map are the well known simplified versions of Jacobi-log Map (Maximum a Posteriori) algorithm already in use but they cannot meet a proper performance in term of output BER and clock consumption of the CPU decoding encoded bits. The proposed algorithm first breaks the correction function domain of the Jacobi logarithm to three subsections by determining the border points between these sections and then uses a linear function and two constant values as an approximation of this function. Using an AWGN channel model, simulation results show that the new algorithm is almost more than six times faster than Jacobi-log Map algorithm with a Bit Error Rate (BER) very close to it.  相似文献   

Analysing intellectual capital management and growth based on dynamic modelling     

Amir?Zakery  Abbas?AfrazehEmail author 《知识管理研究与实践》2017,15(1):101-113

The management of intellectual capital (IC) resources increases organizational value creation capacities. The aim of this study is to present an algorithm for analysing IC management with an emphasis on the recognition and modelling of growth mechanisms for strategic resources. Intensive interactions among different tangible and intangible assets turn organizations into complex systems of highly interrelated resources; therefore, a systems approach is adopted, and a causal loop diagram is used to model resource interaction feedback structures. The development and analysis of the resource interactions model is explained through a practical algorithm that reveals different dimensions of resource deployment, including the potential value of resources, utilization of resources in key business processes, and mechanisms responsible for the sustained growth of strategic resources. The proposed algorithm was used to examine a telecommunication company. We show that there are no growth mechanisms for certain strategic resources. To activate the growth of such strategic resources, several feedback loops are recognized and related initiatives are proposed.  相似文献   

Social and emotional problems associated with integration in the Israeli junior high school     

Yisrael Rich  Yehuda Amir  Rachel Ben-Ari 《Int J Intercult Relat》1981,5(3):259-275

Teachers and pupils in 28 integrated junior high schools in Israel were interviewed and observed to determine the kinds of social and emotional problems encountered in integrated schools. Though these schools are mandated to achieve both academic and social goals, academic aspects of schooling are inordinately stressed while the social goal is neglected. This strategy has major implications for teaching methods, curriculum, tracking, extra-curricular activities and staff morale. Furthermore, while bright, achieving disadvantaged pupils tend to gain socially and emotionally from this strategy, most disadvantaged children sustain significant losses in the social and emotional spheres and meaningful ethnic integration in the school is not achieved. It is recommended that the school invest greater resources in enhancing pupils' social and emotional development and that there be a dual emphasis in integrated schools on academic and personal development. Implementation of this recommendation requires retraining teachers to provide them with concrete skills in both areas that can be applied in the heterogeneous class.  相似文献

The Usual Suspect: A History of Football Violence in the State of Israel     

Amir Ben Porat 《Sport in History》2016,36(1):98-116

Rather than hooliganism per se, violence here is examined both in its totality and the extent to which the history of football violence in Israel has been subject to a fluctuating social, political and economic context. Initially, footballers were ‘the usual suspect’ as violence was often incited by the players on the pitch. For political reasons, the Israel Football Association (IFA) was practically helpless. Over time, violent incidents on the pitch decreased as a change in the pattern of violence took place. Due to an increasing commodification of Israeli football, players and spectators switched places. The crowd was now ‘the usual suspect’ and later, due to the Israeli–Palestinian conflict, ethnicity-nationality became the major trigger for violent actions in Israeli football.  相似文献
