Modern social media frequenters traditionally surround themselves around specific topics or interests, like a television show or sport, which breeds interaction with the people who you have mutual interests with. This is prevalent in social networks like Facebook where users like certain pages that are oriented around a topic, or Twitter users that tag their tweets using hashtags to illustrate a subject, and users of Reddit do the a similar thing with topic-specific sub-categories called subreddits. There are almost 400,000 subreddits which cover almost any category leading Reddit to label itself the "front page of the internet". Our interest in Reddit inclines us to ask: RQ1: Do popular comments, submissions, and subreddits have centrality measures proportional to their karma? RQ2: Does content defined as popular according to Reddit tend to cluster and fall in the same area in the network as other popular content? We expected to find that karma is directly proportional to centrality measures and that all popular content nodes will fall in the same general area as each other. If content is popular in a social network, it tends to have great influence which allows us to predict this.
现代社交媒体的常客通常围绕着特定的话题或兴趣,比如电视节目或体育运动,这促进了与你有共同兴趣的人的互动。这在像Facebook这样的社交网络中很普遍,用户喜欢围绕某个主题的某些页面,或者Twitter用户使用标签来标记他们的推文,以说明一个主题,Reddit的用户也做类似的事情,使用特定主题的子类别,称为subreddits。Reddit有近40万个子版块,几乎涵盖了所有类别,这使得Reddit给自己贴上了“互联网首页”的标签。我们对Reddit的兴趣促使我们问:RQ1:流行评论、提交和子Reddit是否有与它们的业力成比例的中心性度量?RQ2:根据Reddit定义为流行的内容是否倾向于与其他流行内容聚集在网络的同一区域?我们期望发现因果报应与中心性度量成正比,并且所有受欢迎的内容节点将落在彼此相同的一般区域。如果内容在社交网络中很受欢迎,它往往具有很大的影响力,这使我们能够预测这一点。

The authors reported whether there is a positive correlation between the numbers of symptoms and genes shared by a pair of diseases. A new network depicting disease-symptom relationships was introduced and analyzed by comparing it to Goh et al.'s network depicting disease-gene relationships. The two networks had very different structures, and there was essentially no correlation between genetic and symptomatic similarities between diseases. The methodology and findings may inform medical researchers and practitioners about sets of confusing diseases that require particular attention in diagnosis and treatment.
作者报告了症状的数量和一对疾病共有的基因之间是否存在正相关关系。介绍了一种新的描述疾病-症状关系的网络,并将其与Goh等人描述疾病-基因关系的网络进行了比较分析。这两个网络的结构非常不同,疾病之间的基因和症状相似性基本上没有关联。方法和结果可使医学研究人员和从业人员了解在诊断和治疗中需要特别注意的一系列令人困惑的疾病。

Undergraduates are influenced by modern technology such as smart-phone apps, social networks and the Internet. Technology is perceived to be “cool” and students are often interested in gaining expertise in them. However, most of them lack access to the tools/knowledge needed for a developer level involvement and several lack the opportunity to experience the research that creates the “cool stuff” of the future. This research project aims at providing both the tools and the opportunity to undergraduates at a minority serving institution. Through two phases: training and research that spanned from July to December 2014, several undergraduates were engaged in cutting edge Internet and mobile networks research. The training and research objective were to develop android based applications for the MobilityFirst future Internet architecture. The training phase consisted of two 8-week long workshops. The first workshop was to discuss current research in Future Internet Architecture while the second provided training in JAVA programming language and Android application development. In the research phase, nine students participated in developing geo-social network applications that generated content and shared locally in a geographic region. These applications used Wi-Fi Direct and/or MobilityFirst future Internet architecture for communication without the need for wide-area network connectivity.
大学生受到智能手机应用程序、社交网络和互联网等现代技术的影响。科技被认为是“酷”的,学生们经常对获得这方面的专业知识感兴趣。然而,他们中的大多数人无法获得开发人员级别参与所需的工具/知识,有些人没有机会体验创造未来“酷东西”的研究。本研究项目旨在为少数族裔服务机构的本科生提供工具和机会。2014年7月至12月,几名本科生通过培训和研究两个阶段,从事前沿互联网和移动网络的研究。培训和研究的目标是为MobilityFirst未来的互联网架构开发基于android的应用程序。培训阶段包括两个为期8周的讲习班。第一个研讨会是讨论未来互联网架构的当前研究,而第二个研讨会提供JAVA编程语言和Android应用程序开发的培训。在研究阶段,九名学生参与开发地理社交网络应用程序,生成内容并在一个地理区域内进行本地共享。这些应用使用Wi-Fi Direct和/或MobilityFirst未来互联网架构进行通信,而不需要广域网连接。

Teaching for transfer through engineering design 工程设计转移教学
Pub Date : 2015-03-07 DOI: 10.1109/ISECON.2015.7119944

This document outlines a qualitative study with the aim of fostering the transfer of Science, Technology, Engineering, and Math (STEM) content while working through engineering design problems. Teaching for transfer offers a vehicle to foster the transfer of STEM content through the abstraction of knowledge in each individual discipline. Many theoretical approaches to explaining knowledge transfer are rooted in a belief that knowledge becomes generalizable through its abstraction. This study used a case study design. Student participants in this study were engaged in pre-engineering design-based activities and ranged from freshman to seniors. This study also took place in a low-income school district that has a high minority population. This group of students allowed for a unique lens, which looked at under-represented groups and their experience with engineering design. Data were collected through the use of a design log. Student work was aligned with teaching for transfer lessons to identify whether the instruction was fostering the transfer of STEM content. Preliminary findings indicate that when students are overtly made aware of STEM content connections they understand how each discipline can work together to solve a real world problem. Findings such as these have broad applications for curriculum development in the future. If teachers have the tools to teach for transfer and train students how to transfer knowledge they will be better equipped to solve more complex engineering design problems as they get older.
本文件概述了一项定性研究,旨在促进科学、技术、工程和数学(STEM)内容的转移,同时解决工程设计问题。迁移教学通过对每个单独学科的知识进行抽象,为促进STEM内容的迁移提供了一种手段。许多解释知识转移的理论方法都植根于这样一种信念,即知识通过抽象变得可概括。本研究采用案例研究设计。本研究的学生参与了基于工程前期设计的活动,范围从大一到大四。这项研究也在一个少数民族人口较多的低收入学区进行。这组学生提供了一个独特的视角,审视了代表性不足的群体和他们在工程设计方面的经验。通过使用设计日志收集数据。学生的作业与迁移课程的教学相结合,以确定教学是否促进了STEM内容的迁移。初步研究结果表明,当学生公开意识到STEM内容的联系时,他们就会理解每个学科如何协同工作来解决现实世界的问题。这些发现对未来的课程开发具有广泛的应用价值。如果教师有工具来教授知识转移,并训练学生如何转移知识,随着年龄的增长,他们将更好地解决更复杂的工程设计问题。

Infusing the creative-thinking process into undergraduate STEM education: An overview 将创造性思维过程注入本科STEM教育:概述
Pub Date : 2015-03-07 DOI: 10.1109/ISECON.2015.7119945

In this project, we develop and deliver a workshop to teach undergraduate Science, Technology, Engineering and Mathematics (STEM) faculty the creative thinking process and help them to develop modules for their classes. Leaning on ideas back to Plato's Theaetetus, we divide the creative process into seven discrete stages, and have developed exercises to help STEM faculty to explore and internalize these concepts. While we believe that many scientists invoke the creative process in their work regularly, we also believe that learning the creative process and practicing creative-process thinking can help STEM faculty and students to invoke this process more fluidly, expediently, and effectively. Initial feedback from the workshop indicates that the nine faculty who participated in the workshop report an increased understanding of the creative thinking process and increased comfort level with incorporating these ideas into their classes, among other things.
在这个项目中,我们开发并提供了一个研讨会,教授本科科学、技术、工程和数学(STEM)教师创造性思维的过程,并帮助他们为他们的课程开发模块。根据柏拉图的《泰阿泰德》(Theaetetus),我们将创造过程分为七个独立的阶段,并开发了练习来帮助STEM教师探索和内化这些概念。虽然我们相信许多科学家在他们的工作中经常调用创造性过程,但我们也相信学习创造性过程和练习创造性过程思维可以帮助STEM教师和学生更流畅、更方便、更有效地调用这一过程。讲习班的初步反馈表明,参加讲习班的9名教师报告说,他们对创造性思维过程的理解有所增加,并且在将这些想法融入课堂等方面感到更加舒适。

Expanding high school STEM literacy through extra-curricular activities 通过课外活动拓展高中STEM素养
Pub Date : 2015-03-07 DOI: 10.1109/ISECON.2015.7119940
Sahaj Garg
As the movement to expand education in STEM fields grows, there must be a commensurate expansion of extra-curricular opportunities for STEM related fields. STEM extra-curricular activities inherently have a larger effect in increasing the amount of STEM graduates than additional focus in the classroom because they help students develop interests and allow them to gain the experience that is necessary for careers. In order to give students the opportunity to pursue their interests outside the classroom, the IEEE STEM club of Bridgewater-Raritan High School, known as iSTEM, was established. This club gives students the opportunity to pursue their interest in four major ways: by inviting guest speakers, by encouraging student research, presentations and entrepreneurship, by creating hands-on projects, and by offering competitions. A combination of these four will increase interest in STEM, a growing field. There is currently a lack of state level organizations and national organizations to bring together STEM clubs similar to the way Future Business Leaders of America brings together business clubs nationwide. To fill this void, we have created NJ iSTEM, a statewide organization that allows schools across the state to meet up in events such as a hackathon and a state conference. Although we have not yet created a nationwide organization, this is a future option open to exploration.
随着扩大STEM领域教育的运动不断发展,STEM相关领域的课外机会也必须相应扩大。与课堂上的额外关注相比,STEM课外活动在增加STEM毕业生数量方面具有更大的作用,因为它们可以帮助学生培养兴趣,并使他们获得职业所需的经验。为了让学生有机会在课堂之外追求自己的兴趣,布里奇沃特-瑞坦高中的IEEE STEM俱乐部(简称iSTEM)成立了。该俱乐部通过四种主要方式为学生提供了追求自己兴趣的机会:邀请演讲嘉宾,鼓励学生进行研究、演讲和创业,创建动手项目,以及举办竞赛。这四家公司的结合将增加人们对STEM这个不断发展的领域的兴趣。目前缺乏像美国未来商业领袖组织全国商业俱乐部那样将STEM俱乐部聚集在一起的州级组织和全国性组织。为了填补这一空白,我们创建了NJ stem,这是一个全州范围的组织,允许全州的学校在黑客马拉松和州会议等活动中会面。虽然我们还没有建立一个全国性的组织,但这是一个可供探索的未来选择。

Children, even as they are learning to take their first steps are already developing a more intimate relationship with technology that we ever did. Sadly, their relationship with technology is primarily based around consumption, not creation and invention. The educational robotics curriculum for grades 2, 3 and 4 at The School at Columbia is designed to shift this paradigm by giving students access to tools that inspire them to program and invent, becoming tool builders and not merely tool users. With robotics, new skills and concepts are tangible. Children are eager to dive into these new technologies and embrace the challenge of making real what they have imagined. Robotics gives students the opportunity to find new ways to work together, express themselves, problem-solve and think innovatively. Working with and learning from one another is critical to building new knowledge and understanding.
孩子们,即使他们还在学习迈出他们的第一步,他们已经与技术建立了比我们更亲密的关系。可悲的是,他们与技术的关系主要是基于消费,而不是创造和发明。哥伦比亚大学二年级、三年级和四年级的教育机器人课程旨在改变这种模式,让学生接触到激发他们编程和发明的工具,成为工具的建设者,而不仅仅是工具的使用者。有了机器人技术,新的技能和概念是切实可行的。孩子们渴望深入研究这些新技术,接受挑战,把他们想象的东西变成现实。机器人技术为学生提供了寻找合作、表达自我、解决问题和创新思维的新方法的机会。相互合作和相互学习对于建立新的知识和理解至关重要。

Promoting mobile computing and security learning using mobile devices 推广移动计算和使用移动设备进行安全学习
Pub Date : 2015-03-07 DOI: 10.1109/ISECON.2015.7119924

It is of vital importance to provide mobile computing and security education to students in the computing fields. As the mobile applications become increasingly popular and inexpensive ways for people to communicate, share information and take advantage of convenient functionality in people's daily lives, they also regularly attract the interests of malicious attackers. Malware and spyware that may damage smart phones or steal sensitive information are also growing in every aspect of people's lives. Another concern lies in insecure mobile application development. This kind of programming makes mobile devices more vulnerable. For example, some insecure exposures of the APIs or the abuse of some components while developing apps will make the applications suffer from potential threats. Although many academic institutions have started to or planned to offer mobile computing courses, there is a shortage of hands-on lab modules and resources that can be integrated into multiple existing computing courses. In this paper, we present our development on mobile computing and security hands-on Labs and share our experiences in teaching courses on mobile computing and security with students' learning feedback using Android mobile devices.
对计算机专业的学生进行移动计算和安全教育是至关重要的。随着移动应用成为人们日常生活中交流、分享信息和利用便捷功能的日益普及和廉价的方式,它们也经常吸引恶意攻击者的兴趣。可能损坏智能手机或窃取敏感信息的恶意软件和间谍软件也在人们生活的各个方面增长。另一个问题在于不安全的移动应用程序开发。这种编程使移动设备更容易受到攻击。例如,在开发应用程序时暴露一些不安全的api或滥用某些组件将使应用程序遭受潜在的威胁。尽管许多学术机构已经开始或计划提供移动计算课程,但是缺少可集成到多个现有计算课程中的动手实验模块和资源。在本文中,我们介绍了我们在移动计算和安全实践实验室的发展,并分享了我们在移动计算和安全课程教学中的经验,以及学生使用Android移动设备的学习反馈。

As the mobile applications become increasingly popular and inexpensive ways for people to communicate, share information and take advantage of convenient functionality in people's daily lives, they also regularly attract the interests of malicious attackers. Malware and spyware that may damage smart phones or steal sensitive information are also growing in every aspect of people's lives. Another concern lies in insecure mobile application development. This kind of programming makes mobile devices more vulnerable. For example, some insecure exposures of the APIs or the abuse of some components while developing apps will make the applications suffer from potential threats. Although many academic institutions have started to or planned to offer mobile computing courses, there is a shortage of hands-on lab modules and resources that can be integrated into multiple existing computing courses. In this paper, we present our development on mobile computing and security hands-on Labs and share our experiences in teaching courses on mobile computing and security with students' learning feedback using Android mobile devices.","PeriodicalId":386232,"journal":{"name":"2015 IEEE Integrated STEM Education Conference","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134470836","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}

In this integrated STEM learning module we developed a data collection tool and used innovative analysis methods to investigate the relationship between academic achievement and risky wellness behaviors among college students. Exploratory factor analysis (EFA) was performed using data from college students (n = 1,499) at a large north-central university. Advanced machine learning analysis techniques found a strong connection between student wellness behavior and academic achievement and that this relationship can be predicted using wellness behavior data. The real world research project in this study integrated educational activities among Mathematics, Computer Science, and Health Science creating an interdisciplinary learning experience within Science, Technology, Engineering and Mathematics (STEM).
在这个集成的STEM学习模块中,我们开发了一个数据收集工具,并使用创新的分析方法来调查大学生学习成绩与健康风险行为之间的关系。探索性因素分析(EFA)使用来自中北部一所大型大学的大学生(n = 1499)的数据进行。先进的机器学习分析技术发现,学生的健康行为和学业成绩之间存在很强的联系,这种关系可以通过健康行为数据来预测。本研究中的现实世界研究项目整合了数学、计算机科学和健康科学的教育活动,创造了科学、技术、工程和数学(STEM)的跨学科学习体验。
