Disruption and Deception in Crowdsourcing: Towards a Crowdsourcing Risk Framework
While crowdsourcing has become increasingly popular among organizations, it also has become increasingly susceptible to unethical and malicious activities. This paper discusses recent examples of disruptive and deceptive efforts on crowdsourcing sites, which impacted the confidentiality, integrity, and availability of the crowdsourcing efforts’ service, stakeholders, and data. From these examples, we derive an organizing framework of risk types associated with disruption and deception in crowdsourcing based on commonalities among incidents. The framework includes prank activities, the intentional placement of false information, hacking attempts, DDoS attacks, botnet attacks, privacy violation attempts, and data breaches. Finally, we discuss example controls that can assist in identifying and mitigating disruption and deception risks in crowdsourcing
The Gig Economy: Workers, Work and Platform Perspective
In recent years, the gig economy has changed the way many people work. This research phenomenon has attracted scientists from many different fields to an emerging field of research. Given the actuality of the topic and diversity of perspectives, there is a great need to collect and connect what has been researched which can serve as a basis for future discussions. Starting with a collection of 139 publications on the gig economy, gig work and related terms, we identify some trends in the literature and the underlying research interests. In particular, we organize the literature around the concept of the gig economy in terms of gig workers, gig work, and digital platforms, and draw several interesting insights from the literature. Finally, we identify important gaps in the existing literature on working in the gig economy and provide guidance for future research
The Human Flesh Search Engine in China: a case-oriented approach to understanding online collective action
There has been a growing interest in online politics in China. The research mostly focuses on the role of the Internet in two areas, one is its creation of a public sphere and the challenges it poses to the existing communication and political system, and the other one is online censorship undertaken by Chinese authorities to reduce the scope of political discussion online and keep the domestic cyberspace from being merged with foreign cyberspace. However, some political uses of the Internet in China have tended to be overlooked. This thesis seeks to redress this lacuna in research by examining the political focus of a recent Internet phenomenon the Human Flesh Search Engine (HFSE). This term might be more at home in pages of a horror novel but was originally applied by the Chinese media to refer to the practice of online searching for people or human hunting.
While existing examinations have focused on breaches of individual privacy by these so called online vigilantes this study mainly focuses on the ability of HFSE to reveal norms transgressions by public officials and lead to their removal. As the politically-focused HFSE is part of the tendency of Chinese popular protest, it is necessary to explore how the HFSE differs from and is similar to those offline protests in China. A case-oriented approach is applied to the research on HFSE. More specifically, the first part of this research puts the understanding of HFSE in Chinese historical context, with the aim of exploring the common dynamics between HFSE and those historical examples of Chinese bottom-up collective action. Then in the second part, a comparison between HFSE and recent Chinese offline popular protests is conducted in order to establish the pattern of politically-focused HFSE. In the third part, based on the empirical cases, the research on HFSE continues with an exploration of HFSE s underlying causal mechanisms to answer a key question of this research: why did HFSE occur?
The study implies that there are continuities with respect to the Chinese bottom-up collective action as HFSE and Chinese rural resistances as well as urban labour strikes in the twentieth century of China tend to show similar dynamics, which are determined by the power structure they are exposed to. Moreover, the internal process of politically-focused HFSE differs largely from that of recent Chinese offline popular protests, which indicates that HFSE does not have an offline equivalent, although some of its stages can be witnessed offline. Furthermore, HFSE s occurrence is brought about by a combination of online and offline factors, which are relevant to not only the Internet and Chinese cyberspace, but also the political system that has contributed to the growth of official corruption and low government credibility in China
News in an era of content confusion: effects of news use motivations and context on native advertising and digital news perceptions
This study examined the effects of differing native advertising framing contexts (hard versus soft news) and individuals’ news use motivations on ability to perceive commercialized content, evaluations of native advertising, and ensuing digital news perceptions. Based upon the framework of the persuasion knowledge model, an online experiment was conducted among a sample of U.S. adults (N = 684). When revealed as advertising, people were more likely to perceive the hard news rather than the soft news framing as commercial in nature. Furthermore, hard news approaches to native advertising were perceived unfavorably by audiences and tarnished the subsequent reporting of actual journalists.Accepted manuscrip
Polycystic Ovary Syndrome and Non-Suicidal Self-Injury: A community-based study
Polycystic Ovary Syndrome (PCOS) is an endocrine condition that has been associated with atypical emotional regulation strategy use as well as elevated levels of depression, anxiety, self-harm and suicidal ideation. Despite the existence of clinical screening guidance for this population, there is still little to no understanding of how non-suicidal self-injury and suicidal ideation and intention manifest in women with PCOS and how this might differ from women without PCOS. Within this cross-sectional investigation, women with and without a diagnosis of PCOS (n = 418) completed validated metrics of emotion dysregulation, rumination and non-suicidal self-injury (NSSI), as well as self-reported indices of previous suicidal ideation and future suicidal intention. Group comparisons indicated that women with, relative to those without, PCOS reported significantly greater metrics across all variables. Moreover, serial mediation analyses were conducted to test the ideation-to-action framework of suicide in women with PCOS, with the positive relationship between a PCOS diagnosis and future suicidal intention being explained through the indirect pathway of increased emotion dysregulation, recent suicidal ideation and NSSI. Our findings call to action the need for international screening for suicide intention and self-harm in women with PCOS
Enhanced Content-Based Fake News Detection Methods with Context-Labeled News Sources
This work examined the relative effectiveness of multilayer perceptron, random forest, and multinomial naïve Bayes classifiers, trained using bag of words and term frequency-inverse dense frequency transformations of documents in the Fake News Corpus and Fake and Real News Dataset. The goal of this work was to help meet the formidable challenges posed by proliferation of fake news to society, including the erosion of public trust, disruption of social harmony, and endangerment of lives. This training included the use of context-categorized fake news in an effort to enhance the tools’ effectiveness. It was found that term frequency-inverse dense frequency provided more accurate results than bag of words across all evaluation metrics for identifying fake news instances, and that the Fake News Corpus provided much higher result metrics than the Fake and Real News Dataset. In comparison to state-of-the-art methods the models performed as expected
