A Three-Step Data-Mining Analysis of Top-Ranked Higher Education Institutions' Communication on Facebook 排名靠前高校Facebook交流的三步数据挖掘分析
Á. Figueira
Organizations are rushing into social media networks following a worldwide trend to create a social presence in multiple media channels. However, a social media strategy needs to be aligned with and framed in the overall organizational strategic management goals. Higher Educational Institutions (HEI) are not different from other organizations in which concerns these problems. Determining the organizational positioning of an organization current strategy will allow to combine monitoring and benchmarking methods to foster the identification of opportunities and threats, which can serve as inputs for the internal evaluation of social media strategies', for the necessary strategic readjustments and a subsequent efficiency measurement. In order to address these challenges, we propose a three-step automatic data-mining procedure to assess the posting behavior and strategy of HEI, understand the editorial policy behind it, and predict the future HEI engagement. We used a sample of the 5-top ranked educational institutions in 2017. We collected the posts from each HEI official Facebook page during an entire school year. Our method showed high degree of accuracy and is also capable of describing which topics are most common in each university's social media content strategy and relate them to the corresponding response from their publics.
随着在多种媒体渠道中建立社交形象的全球趋势,组织纷纷涌入社交媒体网络。然而,社会媒体战略需要与整个组织的战略管理目标保持一致和框架。高等教育机构(HEI)与关注这些问题的其他组织没有什么不同。确定组织当前战略的组织定位将允许将监测和基准方法相结合,以促进机会和威胁的识别,这可以作为社会媒体战略内部评估的输入,以进行必要的战略调整和随后的效率测量。为了应对这些挑战,我们提出了一个三步自动数据挖掘程序来评估高等教育的发布行为和策略,了解其背后的编辑政策,并预测未来的高等教育参与。我们选取了2017年排名前5位的教育机构作为样本。我们收集了整个学年里HEI官方Facebook页面上的帖子。我们的方法显示出高度的准确性,并且能够描述每个大学的社交媒体内容策略中最常见的主题,并将其与公众的相应反应联系起来。

The diversification of scientific communication: new genders and new models in the context of the Digital Humanities 科学传播的多元化:数字人文语境下的新性别与新模式
J. Cordón-García, María Muñoz-Rico, R. Gómez-Díaz, Araceli García Rodríguez
Scientific communication undergoes changes of growth and model in virtue of phenomena related to the new modes of production and dissemination of documents, which affect their forms of visibility and impact. The nature of the research, affected more and more by the pressure to publish, and by the acceleration of publication times, is increasingly affected by the appearance of phenomena such as those of the predatory Publisher, and the tensions between the large publishing corporations and open access platforms.
科学传播由于文献生产和传播新模式的相关现象而发生增长和模式的变化,影响了其知名度和影响力的形式。研究的性质越来越多地受到出版压力和出版时间加快的影响,越来越多地受到掠夺性出版商、大型出版公司和开放获取平台之间的紧张关系等现象的影响。

The 'supply chain' of teachers' digital skills training: The TPACK traceability in the teachers' trainers 教师数字技能培训的“供应链”:教师培训师的TPACK可追溯性
L. Perla, L. Agrati, V. Vinci
Starting from the stimuli coming from the TPCK model [30], the work invites to discuss the type of technological competence required today by the teacher for a 'wise' [27] and effective use of digital tools at school. The 'supply chain' metaphor will be used in order to describe the epistemic process that transforms European priorities into national competences of teachers. Specifically, a model of 'traceability' of the TPACK - that from the DigiComp Edu Framework leads up to the local training in the school-centres pole through the Italian National Digital Plan (PNSD), obtained from a survey using a questionnaire - will be proposed in order to reflect on the coherence between the general priorities and the actual formulation.
从TPCK模型[30]的刺激开始,该工作邀请讨论当今教师在学校“明智”[27]和有效使用数字工具所需的技术能力类型。将使用“供应链”比喻来描述将欧洲优先事项转变为教师国家能力的认知过程。具体来说,将提出一个TPACK的“可追溯性”模型——从DigiComp Edu框架到通过意大利国家数字计划(PNSD)在学校中心进行的地方培训,通过使用问卷调查获得——以反映总体优先事项与实际制定之间的一致性。

University Media in Ecuador: Types, Functions and Self-Determination 厄瓜多尔的大学媒体:类型、功能和自主性
Juan Pablo Trámpuz, D. B. Ibáñez, C. A. Calderón, Eduar Barbosa Caro
The university media are actors that, being attached to Higher Education Institutions (HEI), try to find a balance between media and education. This situation generates a series of peculiarities that differentiate them from their commercial counterparts. The present article proposes to define the types, functions and self-determination of the Ecuadorian university media, through a documentary review of the researches developed in this field, and the application of structured interviews to its directors. The results allow identifying the characteristics of the Ecuadorian university media, marked by the institutional model that is ascribed to the academic units, a range of functions that respond to institutional needs, and a self-determination that, at times, differs from the HEI type. which is ascribed to align with the community or generate a mixture beyond what is determined in current Ecuadorian regulations, ratifying their status as differentiated actors in the national media scenario.
大学媒体是依附于高等学校的行动者,他们试图在媒体和教育之间找到平衡。这种情况产生了一系列的特点,使它们与商业对手区别开来。本文建议通过对这一领域的研究进行文献回顾,并对其董事进行结构化访谈,来定义厄瓜多尔大学媒体的类型、功能和自决。研究结果可以确定厄瓜多尔大学媒体的特点,其特点是归于学术单位的机构模式、响应机构需求的一系列功能,以及有时不同于高等教育机构类型的自我决定。这被认为是为了与社区保持一致,或产生超出厄瓜多尔现行法规所确定的混合,认可他们在国家媒体情境中的特殊角色地位。

Blended Mobility: a way for the Sustainable Internationalization of Higher Education 混合流动:高等教育可持续国际化之路
N. Escudeiro, P. Escudeiro
Modern economy requires engineers to excel in collaborative and communication skills at an international setting. However, these competences are not usually addressed in most engineering curricula. In the Multinational Undergraduate Team Work course, MUTW, students develop their capstone project as members of an international team while working at their home institutions. Team members are geographically spread to assure heterogeneous teams and to promote international cooperation. This paradigm can be applied in any project/internship course unit. The results from the pilot editions that ran between 2009 and 2011 support our initial hypothesis that MUTW significantly promotes students' soft skills without requiring costly and time consuming changes to prior degree curricula.
现代经济要求工程师在国际环境中具有出色的协作和沟通能力。然而,这些能力通常不涉及大多数工程课程。在MUTW的跨国大学本科团队工作课程中,学生们在自己的学校工作时,作为国际团队的成员来开发他们的终极项目。团队成员在地理上分散,以确保异质团队并促进国际合作。此范例可应用于任何项目/实习课程单元。2009年至2011年间的试点结果支持了我们最初的假设,即MUTW可以显著提高学生的软技能,而不需要对先前的学位课程进行昂贵和耗时的更改。

Mapping the systematic literature studies about software ecosystems 对软件生态系统的系统文献研究进行梳理
A. Holgado, F. García-Peñalvo
There is a need to improve the definition and development of technological ecosystems in order to solve the main problems detected in previous studies. To achieve this goal, it is required to identify and analyse the solutions available in the literature in the field of software engineering applied to ecosystems. The research in software ecosystems is a relatively young research area, but there are already several works that analyse the literature associated. To conduct a new systematic literature review is necessary to ensure that there are no studies that do the same, namely, that do not answer the same research questions. The identification of the need for a review was done through a study focused on systematic literature reviews and mapping studies about software ecosystems. This work aims to describe the mapping conducted as part of that study. It provides a global state of the art of this kind of studies in the area of software ecosystems.
为了解决以往研究中发现的主要问题,有必要改进技术生态系统的定义和发展。为了实现这一目标,需要识别和分析应用于生态系统的软件工程领域的文献中可用的解决方案。软件生态系统的研究是一个相对年轻的研究领域,但是已经有一些作品分析了相关的文献。进行一项新的系统文献综述是必要的,以确保没有研究做同样的事情,即没有回答同样的研究问题。通过对软件生态系统的系统文献回顾和地图研究,确定了审查的必要性。这项工作的目的是描述作为该研究的一部分进行的绘图。它提供了软件生态系统领域中这类研究的全球最新状态。

How to correct the behavior of citizens from public entities?: The case of Nudges 如何从公共实体中纠正公民的行为?: Nudges案例
Marta Cerezo Prieto, Ricardo Rivero Ortega, F. Esteban
In this article my PhD research plan will be presented. This work revolves around communication and perception strategies that serve as guidelines for public administrations. Currently the science of behavior has taken a turn with the arrival of mass communication. In this sense, the agents that need to reach the population to make sense, such as public administrations, have changed their communication, marketing and message design strategies. This Project aims to analyze the behavior and reactions of different types of public to certain messages by public administrations to know whether these messages work or not. To do this, we will use traditional methodologies such as observation and analysis of official data and experimental methodologies in the application of strategies in order to know their effectiveness. When this investigation is completed, it is expected to offer a guide of good practices on the incidence of these strategies by public administrations on the behavior of citizens. This research work is divided into five sections: Context and motivation that drives the dissertation research; State-of-the-art; Research objectives and research questions; Research approach and methods; and Conclusions and future work.
这篇文章将介绍我的博士研究计划。这项工作围绕着作为公共行政指导方针的沟通和感知战略展开。目前,随着大众传播的到来,行为科学发生了转折。从这个意义上说,需要接触人口的代理人,如公共管理部门,已经改变了他们的沟通、营销和信息设计策略。本项目旨在分析不同类型的公众对公共管理部门的某些信息的行为和反应,以了解这些信息是否有效。为了做到这一点,我们将使用传统的方法,如观察和分析官方数据和实验方法在策略的应用,以了解其有效性。这项调查完成后,预期将提供一份良好做法指南,说明公共行政部门对公民行为采取这些战略的情况。本研究工作分为五个部分:驱动论文研究的背景和动机;最先进的;研究目标和研究问题;研究途径和方法;结论和未来工作。

Digital Tools for the Didactics of Colour in Fine Arts Studies: Remarks on Colour 美术研究中色彩教学的数字工具:对色彩的评论
Carmen González García, Felicidad García-Sánchez, J. S. González, Victor García, A. Fernández, José Gómez Isla
This paper includes the results of an experience of educational innovation for the study of color structures carried out with the students of the Degree in Fine Arts of the University of Salamanca during the 2017-2018 academic year. This experience was explicitly focused on the introduction of digital tools that contribute to the acquisition of necessary skills such as the ability to analyze the chromatic structure of the pictorial work and its critical commentary, and to complement traditional color learning based on mixing of color on the palette. With this aim, we have initially worked with the digital tool Google Cloud's Vision API for the first analysis and we have finished the experience with Adobe Color CC, a complementary tool that allows the creation of own schemes. The project started with the coordination of contents and teaching experiences in related subjects in the Degree in Fine Arts. This includes both practical subjects of the areas of Painting and Drawing in which content related to color, chromatic vocabulary and manipulation of parameters are developed in depth, as well as the theoretical subjects of History and Art Theory in which an analysis of color for the elaboration of critical comments is needed. This paper explains the working process and the result of the experience once the above-mentioned tools were applied to the image analysis in the classroom.
本文包括萨拉曼卡大学美术学位学生在2017-2018学年进行的色彩结构研究的教育创新经验的结果。这种经验明确地集中在数字工具的引入上,这些工具有助于获得必要的技能,例如分析绘画作品的色彩结构及其批判性评论的能力,并补充基于调色板上颜色混合的传统色彩学习。带着这个目标,我们最初使用数字工具Google Cloud的Vision API进行了第一次分析,我们已经完成了使用Adobe Color CC的体验,这是一个允许创建自己方案的补充工具。本课题从协调美术学位相关学科的内容和教学经验入手。这包括绘画和绘图领域的实践科目,其中与颜色、色彩词汇和参数操作相关的内容得到了深入的发展,以及历史和艺术理论的理论科目,其中需要对颜色进行分析,以阐述批判性评论。本文阐述了将上述工具应用于课堂图像分析的工作过程和经验结果。

Big Data in Education: Detection of ICT Factors Associated with School Effectiveness with Data Mining Techniques 教育中的大数据:用数据挖掘技术检测与学校有效性相关的ICT因素
F. Martínez-Abad, Adriana Gamazo, M. Rodríguez-Conde
The search for non-contextual process factors associated with school effectiveness has become a line of research with very broad dissemination, primarily from the ubiquity of research that includes analysis of secondary data from large-scale evaluations. With the aim of detecting ICT factors related to school effectiveness from the Spanish sample of the PISA 2015 evaluation, this work applies statistical techniques of data mining, specifically decision trees, for the optimization of the process. The results demonstrate that, while the availability and excessive use of ICTs, both in the educational environment and in the home, are factors associated with low effectiveness, other more personal characteristics of the pupils, such as their perception of self-efficacy in the management of ICT, or their own interest in the use of technologies, can be considered as factors in the protection of school effectiveness. We conclude by discussing the relationship between school effectiveness and academic performance through the analysis of previous studies, focusing on the common elements detected within both perspectives.
寻找与学校有效性相关的非情境过程因素已经成为一种传播非常广泛的研究,主要来自于无处不在的研究,其中包括对大规模评估的次要数据的分析。为了从2015年PISA评估的西班牙样本中发现与学校有效性相关的ICT因素,这项工作应用了数据挖掘的统计技术,特别是决策树,以优化这一过程。结果表明,尽管在教育环境和家庭中,信息通信技术的可用性和过度使用都是与低有效性相关的因素,但学生的其他更个性化的特征,如他们对信息通信技术管理的自我效能感的感知,或他们对技术使用的兴趣,可以被视为保护学校有效性的因素。最后,我们通过对以往研究的分析来讨论学校效能与学习成绩之间的关系,重点关注在这两个视角中发现的共同因素。

Artificial intelligence and the automatic classification of historical photographs 人工智能和历史照片的自动分类
Florian Eiler, Simon Graf, W. Dorner
The amount of historical photographs is a challenge for archives with regard to analyzing, documenting and structuring archival material and make it retrievable and accessible. Established human centric concepts will not be able to handle the instream of un- or semi-structured material or handle analogue documentation. We suggest the use of artificial intelligence to pre-classify and organize historic photographs in collections and archives. With regard to uncertainty the concept of artificial intelligence based classification is discussed based on two questions: (1) What is the uncertainty in current archival documentation, assuming that the quality and completeness of a current classification depends on the partial and restricted knowledge of a person?

历史照片的数量是档案馆在分析、记录和组织档案材料并使其可检索和利用方面面临的挑战。已建立的以人为中心的概念将无法处理非结构化或半结构化的材料流或处理模拟文档。我们建议使用人工智能对收藏和档案中的历史照片进行预分类和组织。关于不确定性,基于人工智能分类的概念基于两个问题进行了讨论:(1)假设当前分类的质量和完整性取决于个人的部分和有限知识,那么当前档案文件中的不确定性是什么?(2)算法概念是否有助于量化不确定性水平?在对算法和经典过程进行比较的基础上,讨论了文档化方面的问题。在一个案例研究中,对人工智能对量化不确定性的贡献进行了测试。为此,人工神经网络/卷积神经网络在一组历史照片上进行了训练和测试。

Established human centric concepts will not be able to handle the instream of un- or semi-structured material or handle analogue documentation. We suggest the use of artificial intelligence to pre-classify and organize historic photographs in collections and archives. With regard to uncertainty the concept of artificial intelligence based classification is discussed based on two questions: (1) What is the uncertainty in current archival documentation, assuming that the quality and completeness of a current classification depends on the partial and restricted knowledge of a person? (2) Can algorithmic concepts help to quantify the level of uncertainty? The aspect of documentation is discussed based on a comparison of algorithms and classical processes. The contribution of artificial intelligence to quantify the uncertainty is tested in a case study.
