Spatial Discovery of Linked Research Datasets and Documents at a Spatially Enabled Research Library     

Sara Lafia  Werner Kuhn 《Journal of Map & Geography Libraries》2018,14(1):21-39

Current publishing practices in academia tend to result in datasets that are difficult to discover. This is because datasets are not well-integrated across academic domains and they are often not linked to the documents that reference them. For these reasons, discovering datasets across domains can be challenging; for example, discovering archeological observations and biological specimens using the same search is not widely supported, even if both datasets share a similar spatial extent, like Mesoamerica. It is also challenging to retrieve relevant documents that reference datasets; for example, retrieving a series of field reports that reference archeological observations is typically not supported. Our work develops an extensible method for: (1) geographically integrating collections across disciplinary repositories and (2) connecting datasets to related documents. We describe a collection of spatially-referenced researcher datasets, capturing their metadata elements and encoding them as linked open data. We then leverage existing library services to formalize links from datasets to documents. The system described in this work has been deployed, resulting in an experimental open data site for the UCSB campus. Results indicate that this system can be scaled-up with support from an institutional repository in the near future.  相似文献   

An impulse to exploit: the behavioral turn in data-driven marketing     

Anthony Nadler  Lee McGuigan 《Critical Studies in Media Communication》2018,35(2):151-165

Industry advocates argue that by tailoring services and commercial solicitations to match media users’ personal interests, data-driven marketing benefits both consumers and businesses. This article shows, however, that advertisers and marketers who are taking up ideas and techniques from behavioral economics tell their clients a very different story about the aims and use of digital marketing and consumer surveillance. Listening in on this discourse demonstrates that some digital marketers conceptualize their own practices as forms of social control, appropriating concepts from behavioral economics to identify consumers’ cognitive and affective biases and target their vulnerabilities. Behavioral economics recognizes that economic decisions are not simply dictated by rational self-interest; rather, such choices depend on cognitive heuristics and habits, and can be manipulated through the design of “choice architecture.” This article discusses implications of the behavioral turn in data-driven marketing for critical advertising scholars, public advocates, and regulators.  相似文献

西非—中国航线原油远洋运输方案优化     

周晓玲  王震  肖文涛  许国栋 《上海海事大学学报》2017,38(1):31-36

为满足西非—中国航线的原油远洋运输方案的时效性要求,以油船运费、滞期费和靠港费之和最低为目标函数,以供需平衡、港口水深和装卸时间为约束条件,求解一个包含船型组合、装/卸港航线组合、油种替换、批次拆分等多决策变量的大规模NP(Non-deterministic Polynomial)难问题.采用差分进化算法进行求解.为提高求解速度,采用双染色体编码、基因组压缩编码、船型与拼装变量隐式联锁、配送油种比对解码等方法,进行供需平衡约束,降低问题规模,并缩减问题的"劣质解空间",提高差分进化算法的搜索时效.利用提出的算法对中国石化某月度西非—中国航线实际原油远洋运输方案进行优化,得到优化方案平均用时约5 min,可节约运费50余万美元.  相似文献   

Accounting for quality: arts evaluation,public value and the case of “Culture counts”     

Abigail Gilmore  Hilary Glow  Katya Johanson 《Cultural Trends》2017,26(4):282-294

Arts policy has a longstanding relationship with the concept of “quality” and the ways in which organisations measure, evaluate and account for it. Culture Counts, an evaluation system and digital platform, compiles data from standardised evaluation surveys of different stakeholder groups – organisations, audiences, critics, funders and peers – and provides the means to compare and triangulate data in an accessible format. As a result, it claims to provide a more effective, democratic tool for quality measurement of art, which demonstrates the public value of funding [Department of Culture and the Arts, & Knell, J. (2014). Public value measurement framework: Measuring the quality of the arts. Perth: Department of Culture and the Arts.]. Through qualitative research with two consortia of organisations involved in Culture Counts pilot projects in Manchester, England and Victoria, Australia, we explore these claims, comparing the reception and promotion of the system in both countries and considering its potential incorporation into policy assessment frameworks and adoption within arts organisations’ existing evaluation capacities.  相似文献

The effect of anticipated achievement feedback on students' semantic processing as indicated by the N400 cloze effect     

《Learning and Instruction》2017

The present study examined the effects of anticipated achievement feedback on students' semantic processing on the neural level, using event-related brain potentials (ERPs). Participants (N = 79) anticipated either self-referential or normative achievement feedback regarding an announced upcoming test. Additionally, their performance expectations (low vs. no expectations) were orthogonally manipulated. Subsequently, students' on-line semantic processing was assessed by measuring the N400 cloze effect, a component in the EEG signal of which the amplitude is associated with semantic processing. Within the low performance-expectation condition, no effect of anticipated feedback on semantic processing was found. Within the no-performance-expectation condition, participants anticipating self-referential feedback showed a more widely distributed N400 cloze effect than participants anticipating normative feedback. The results confirmed the hypothesis that the mere expectation of a particular type of feedback can affect students' semantic processes.  相似文献   

Multimodal data as a means to understand the learning experience     

《International Journal of Information Management》2019

Most work in the design of learning technology uses click-streams as their primary data source for modelling & predicting learning behaviour. In this paper we set out to quantify what, if any, advantages do physiological sensing techniques provide for the design of learning technologies. We conducted a lab study with 251 game sessions and 17 users focusing on skill development (i.e., user's ability to master complex tasks). We collected click-stream data, as well as eye-tracking, electroencephalography (EEG), video, and wristband data during the experiment. Our analysis shows that traditional click-stream models achieve 39% error rate in predicting learning performance (and 18% when we perform feature selection), while for fused multimodal the error drops up to 6%. Our work highlights the limitations of standalone click-stream models, and quantifies the expected benefits of using a variety of multimodal data coming from physiological sensing. Our findings help shape the future of learning technology research by pointing out the substantial benefits of physiological sensing.  相似文献
