Available in PDF, EPUB and Kindle. Book excerpt: Online advertising is a core part of the modern web; ads sustain websites that provide free content and services to consumers, and inform people about products that they may be interested in. However, the ubiquity of the online advertising ecosystem makes it a potent vector for abuse; malicious actors can use the infrastructure of ad networks to serve scams, malware, and other misleading or detrimental content to millions of users across millions of websites. Though the ad networks that provide this infrastructure make efforts to prevent inappropriate and harmful content from appearing on their platforms through content moderation, many kinds of deceptive and unpleasant ads regularly appear on people's screens. Due to the opacity of the online advertising ecosystem, it is challenging for external observers to assess the harms and scale of problematic online ads. This dissertation presents a systematic investigation of the nature and prevalence of problematic content in online advertising, or "bad ads", on the modern web, through four studies. First, this work investigates users' perceptions of online advertising, characterizing the reasons why people dislike (and like) ads, and identifying types of ad content which engender negative reactions. Second, this work quantitatively measures the phenomenon of "clickbait" advertising on news and media websites. Using data crawled from over 7000 news and media websites, this work finds that native advertising networks are strong drivers of problematic content such as content farms and advertorials, and are extremely common across a variety of news websites. Third, this work examines problematic content in online political advertising during the 2020 U.S. elections. In a longitudinal measurement study, this work finds evidence of multiple categories of deceptive political content in online ads, including misleading polls and petitions, political clickbait, and misleading political-themed product ads, and found that these ads were targeted at partisan news sources. Lastly, this work empirically measures the targeting of online ads more broadly, through a unique field study using data collected from 286 real users. This dataset provides measurements of the prevalence of different categories of ad content, how such categories are targeted across websites and demographic groups, the monetary value placed on users by advertisers. Together, these works provide a foundation for future regulation, policy, and research aiming to curb problematic content in online advertising, and improve the overall experience for users on the web.

Available in PDF, EPUB and Kindle. Book excerpt: User engagement refers to the quality of the user experience that emphasizes the positive aspects of interacting with an online application and, in particular, the desire to use that application longer and repeatedly. User engagement is a key concept in the design of online applications (whether for desktop, tablet or mobile), motivated by the observation that successful applications are not just used, but are engaged with. Users invest time, attention, and emotion in their use of technology, and seek to satisfy pragmatic and hedonic needs. Measurement is critical for evaluating whether online applications are able to successfully engage users, and may inform the design of and use of applications. User engagement is a multifaceted, complex phenomenon; this gives rise to a number of potential measurement approaches. Common ways to evaluate user engagement include using self-report measures, e.g., questionnaires; observational methods, e.g. facial expression analysis, speech analysis; neuro-physiological signal processing methods, e.g., respiratory and cardiovascular accelerations and decelerations, muscle spasms; and web analytics, e.g., number of site visits, click depth. These methods represent various trade-offs in terms of the setting (laboratory versus ``in the wild''), object of measurement (user behaviour, affect or cognition) and scale of data collected. For instance, small-scale user studies are deep and rich, but limited in terms of generalizability, whereas large-scale web analytic studies are powerful but negate users' motivation and context. The focus of this book is how user engagement is currently being measured and various considerations for its measurement. Our goal is to leave readers with an appreciation of the various ways in which to measure user engagement, and their associated strengths and weaknesses. We emphasize the multifaceted nature of user engagement and the unique contextual constraints that come to bear upon attempts to measure engagement in different settings, and across different user groups and web domains. At the same time, this book advocates for the development of ``good'' measures and good measurement practices that will advance the study of user engagement and improve our understanding of this construct, which has become so vital in our wired world.

Available in PDF, EPUB and Kindle. Book excerpt: Web mining has become a popular area of research, integrating the different research areas of data mining and the World Wide Web. According to the taxonomy of Web mining, there are three sub-fields of Web-mining research: Web usage mining, Web content mining and Web structure mining. These three research fields cover most content and activities on the Web. With the rapid growth of the World Wide Web, Web mining has become a hot topic and is now part of the mainstream of Web - search, such as Web information systems and Web intelligence. Among all of the possible applications in Web research, e-commerce and e-services have been iden- fied as important domains for Web-mining techniques. Web-mining techniques also play an important role in e-commerce and e-services, proving to be useful tools for understanding how e-commerce and e-service Web sites and services are used, e- bling the provision of better services for customers and users. Thus, this book will focus upon Web-mining applications in e-commerce and e-services. Some chapters in this book are extended from the papers that presented in WMEE 2008 (the 2nd International Workshop for E-commerce and E-services). In addition, we also sent invitations to researchers that are famous in this research area to contr- ute for this book. The chapters of this book are introduced as follows: In chapter 1, Peter I.

Available in PDF, EPUB and Kindle. Book excerpt: The cardiovascular system consists of the heart and the vasculature. The physiology of the system is to circulate blood through the vasculature ensuring delivery of oxygen and vital nutrients to cells and organs in the body. Consequences of diseases disrupting normal cardiovascular function can be severe or fatal. Recent advancements in cardiovascular medicine have contributed significantly to improving life span and quality for patients by restoring normal cardiovascular function through the use of implantable devices. Examples of these cardiovascular implantable devices include endovascular stents, embolic protection devices and filters, closure devices, heart valve prostheses, cardiac rhythm management devices, such as pacemakers and defibrillators, and left ventricular assist devices. The main objective of this chapter is to provide an overview of device test methods commonly used in the development process from concept to commercialization of implantable cardiovascular devices. It is recognized that general device testing methodology and understanding for developing these cardiovascular devices can be extended to other devices as well as new product concepts under development. Developments of new medical devices are closely regulated by regulatory agencies. U.S. and international regulatory requirements for medical devices and drugs provide specific guidance for bench-top in vitro testing, in vivo animal study, clinical research, manufacturing, sterilization, and post-market surveillance for various device categories. Implantable cardiovascular devices generally fall within the Class II and Class III categories. Commercialization of these products in the United States requires FDA's Premarket Notifications (510Ks), Premarket Approvals (PMAs), or Exemptions. The design control element in the new product development procedure requires detailed documentation of design inputs and outputs as well as rational design verification through testing to ensure device functions and safety. Notably, implantable cardiovascular devices are subjected to very high safety expectation. The inability to perform periodic inspection and repair after device implantation also means that the statistical reliability and safety for these devices must be well established and verified prior to clinical uses. To facilitate discussions, a brief overview of the cardiovascular anatomy and physiology is provided in the beginning of this chapter. Following this overview are sections reviewing exemplary implantable devices used for treating various cardiovascular disorders. The majority of this chapter is then devoted to descriptions of necessary engineering characterizations and design verification test methods most relevant to developing cardiovascular devices for commercialization. Particular emphasis is placed on the attributes that are significantly affected by the biomaterials used in the designs. These include physical properties, such as the transformation temperatures for nitinol self-expanding devices, mechanical properties, structure integrity and durability, corrosion risk assessment as well as functional testing. In addition, biocompatibility testing refers to a battery of testing used to evaluate the biological reaction of the human body to the implanted device. There is a well-recognized ISO standard that governs the specific test protocol requirements (ISO 10993). Safety evaluation studies (in vitro and in vivo) are conducted on a variety of biomaterials, medical devices, and related products to identify the presence of toxins or any other potentially harmful effects. Common assessments of device imaging are also briefly described. These include radiopacity as well as magnetic resonance imaging (MRI) safety and compatibility.

Book excerpt: Over a decade ago, tech companies began using algorithms to personalize our experience of the web. Using sophisticated technology and vast amounts of consumer data, companies began to predict our tastes better than we could ourselves. In response, ecommerce expanded, and journalism adapted itself to the personalized attention economy. However, there was a hidden side effect, which Eli Pariser termed "the filter bubble," which is the exclusion of other perspectives from our tech-assisted preferences. Raising many hard questions including data security, political propaganda, and the pervasiveness of digital "junk food," filter bubbles reveal the future challenges of a personalized, automated web. Features such as media literacy questions and terms enhance this collection, encouraging readers to analyze reporting styles and devices.
