Introducing People With Asd To Crowd Work, Kotaro Hara, Jeffrey P. Bigham
Research Collection School Of Computing and Information Systems
Adults with Autism Spectrum Disorders (ASD) are unemployed at a high rate, in part because the constraints and expectations of traditional employment can be difficult for them. In this paper, we report on our work in introducing people with ASD to remote work on a crowdsourcing platform and a prototype tool we developed by working with participants. We conducted a six-week long user-centered design study with three participants with ASD. The early stage of the study focused on assessing the abilities of our participants to search and work on micro-tasks available on the crowdsourcing market. Based on our preliminary findings, …
Crowdsourcing: A New Tool For Policy-Making?, Araz Taeihagh
Crowdsourcing: A New Tool For Policy-Making?, Araz Taeihagh
Research Collection School of Social Sciences
Crowdsourcing is rapidly evolving and applied in situations where ideas, labour, opinion or expertise of large groups of people is used. Crowdsourcing is now used in various policy-making initiatives; however, this use has usually focused on open collaboration platforms and specific stages of the policy process, such as agenda-setting and policy evaluations. Other forms of crowdsourcing have been neglected in policy-making, with a few exceptions. This article examines crowdsourcing as a tool for policy-making and explores the nuances of the technology and its use and implications for different stages of the policy process. The article addresses questions surrounding the role …

High variability interchange times often significantly affect the reliability of metro travels. Fine-grained measurements of interchange times during metro transfers can provide valuable insights on the crowdedness of stations, usage of station facilities and efficiency of metro lines. Measuring interchange times in metro systems is challenging since agentoperated systems like automatic fare collection systems only provide coarse-grained trip information and popular localization services like GPS are often inaccessible underground. In this paper, we propose a smartphone-based interchange time measuring method from the passengers’ perspective. It leverages low-power sensors embedded in modern smartphones to record ambient contextual features, and utilizes a …
Smartphone Sensing Meets Transport Data: A Collaborative Framework For Transportation Service Analytics, Yu Lu, Archan Misra, Wen Sun, Huayu Wu
Smartphone Sensing Meets Transport Data: A Collaborative Framework For Transportation Service Analytics, Yu Lu, Archan Misra, Wen Sun, Huayu Wu
Research Collection School Of Computing and Information Systems
We advocate for and introduce TRANSense, a framework for urban transportation service analytics that combines participatory smartphone sensing data with city-scale transportation-related transactional data (taxis, trains etc.). Our work is driven by the observed limitations of using each data type in isolation: (a) commonly-used anonymous city-scale datasets (such as taxi bookings and GPS trajectories) provide insights into the aggregate behavior of transport infrastructure, but fail to reveal individual-specific transport experiences (e.g., wait times in taxi queues); while (b) mobile sensing data can capture individual-specific commuting-related activities, but suffers from accuracy and energy overhead challenges due to usage artefacts and lack …
Evaluating Relevance And Reliability Of Twitter Data For Risk Communication, Xiaohui Liu
Evaluating Relevance And Reliability Of Twitter Data For Risk Communication, Xiaohui Liu
Dissertations
While Twitter has been touted to provide up-to-date information about hazard events, the relevance and reliability of tweets is yet to be tested. This research examined the relevance and reliability of risk information extracted from Twitter during the 2013 Colorado floods using five different approaches. The first approach examined the relationship between tweet volume and precipitation amount. The second approach explored the relationship between geo-tagged tweets and degree of damage. In the third approach, the spatiotemporal distribution of tweets was compared with flood extent. In the fourth approach, risk information from tweets were compared with survey responses obtained in a …
The Mobile Monitoring Of Particulate Matter Through Wearable Sensors And Their Influence On Students' Environmental Attitudes, Joseph M. Abbate
The Mobile Monitoring Of Particulate Matter Through Wearable Sensors And Their Influence On Students' Environmental Attitudes, Joseph M. Abbate
DePaul Discoveries
While we have a comprehensive understanding of air pollutants, and their spatiotemporal characteristics across global, and even regional, scales, we are quite limited in our capacity to monitor neighborhood-scale emissions. The mobile monitoring of air pollution is a growing field, prospectively filling in these gaps while personalizing air quality-based tools and risk assessment. In the present study, we developed wearable sensors for particulate matter (PM); and through a citizen science approach, students of partnering Chicago schools monitored PM concentrations throughout their commutes over a five-day period. While their recorded findings would be used to explore the relationship between PM concentrations …

Crowdsourced Delphis: Designing Solutions To Complex Environmental Problems With Broad Stakeholder Participation, Sarah Coleman, Stephanie Hurley, Christopher Koliba, Asim Zia
College of Agriculture and Life Sciences Faculty Publications
There is a well-established need for increased stakeholder participation in the generation of adaptive management approaches and specific solutions to complex environmental problems. However, integrating participant feedback into current science, research, and decision-making processes is challenging. This paper presents a novel approach that marries a rigorous Delphi method, borrowed from policy and organizational sciences, with contemporary “crowdsourcing” to address the complex problems of water pollution exacerbated by climate change in the Lake Champlain Basin. In an online Delphi forum that occurred over a six-week period during the Spring of 2014, fifty-three participants proposed and commented on adaptive solutions to address …
Unique Prediction Of Cannabis Use Severity And Behaviors By Delay Discounting And Behavioral Economic Demand, Justin C. Strickland, Joshua A. Lile, William W. Stoops
Unique Prediction Of Cannabis Use Severity And Behaviors By Delay Discounting And Behavioral Economic Demand, Justin C. Strickland, Joshua A. Lile, William W. Stoops
Psychology Faculty Publications
Few studies have simultaneously evaluated delay discounting and behavioral economic demand to determine their unique contribution to drug use. A recent study in cannabis users found that monetary delay discounting uniquely predicted cannabis dependence symptoms, whereas cannabis demand uniquely predicted use frequency. This study sought to replicate and extend this research by evaluating delay discounting and behavioral economic demand measures for multiple commodities and including a use quantity measure. Amazon.com’s Mechanical Turk was used to sample individuals reporting recent cannabis use (n = 64) and controls (n = 72). Participants completed measures of monetary delay discounting as well as alcohol …

Crowdsourcing Digital Public History, Jason A. Heppler, Gabriel K. Wolfenstein
Crowdsourcing Digital Public History, Jason A. Heppler, Gabriel K. Wolfenstein
Jason Heppler
The generation of communal knowledge is not a new phenomenon. In the late nineteenth century, the Oxford English Dictionary solicited volunteers to submit words and their usage for inclusion in the dictionary ( 1 ). Carl Becker, writing in 1932 on what was already an old discussion in the historical profession, noted that "if the essence of history is the memory of things said and done, then it is obvious that every normal person, Mr. Everyman, knows some history" (2). The historian Jo Guldi's work on participatory mapping shows that urban planners in the middle of the twentieth century attempted …

Encounters With Authority: Tactics And Negotiations At The Periphery Of Participatory Platforms, Gabriel Mugar
Dissertations - ALL
Digital participatory platforms like Wikipedia are often celebrated as projects that allow anyone to contribute. Any user can sign up and start contributing immediately. Similarly, projects that engage volunteers in the production of scientific knowledge create easy points of entry to make contributions. These low barriers to entry are a hallmark feature in digital participatory labor, limiting the number of hoops a new volunteer has to jump through before they can feel like they are making a difference. Such low barriers to participation at the periphery, or edges of participatory platforms, have presented a problem for organizational scholars as they …
How Facebook Has Transformed Journalism, Sarah E. Rodriguez
How Facebook Has Transformed Journalism, Sarah E. Rodriguez
Senior Honors Theses
Journalists use Facebook as a tool to distribute information to the public. Over recent years, Facebook with its updated features has changed the way journalists interact with readers and sources. Facebook Live and Instant Articles have increased reader engagement. Journalists use crowdsourcing and conversationally-toned posts to gather information and connect with readers on a personal level. The journalistic process has accelerated since the addition of Facebook because news is disseminated almost instantaneously. Yet the rise in fake news challenges journalists to effectively use Facebook as a platform for news dissemination. Facebook is using fact checkers and increased awareness to fight …

Many Hands Make Light Work: Crowdsourced Ratings Of Medical Student Osce Performance, Mark Grichanik
USF Tampa Graduate Theses and Dissertations
Clinical skills are often measured using objective structured clinical examinations (OSCEs) in healthcare professions education programs. As with assessment centers, it is challenging to provide learners with effective feedback due to burdensome human capital demands. The aim of this dissertation was to evaluate the viability of using a crowdsourced system to gather OSCE ratings and feedback. Aggregating evaluations of student performance from a crowd of patient proxies has the potential to mitigate biases associated with single-rater evaluations, allow the patient a voice as the consumer of physician behavior, improve reliability, reduce costs, improve feedback latency, and help learners develop a …

Crowdsourcing technologies, strategies and methods offer new opportunities for bridging existing gaps among law, policymaking, and the lived experience of citizens. In recent years, a number of initiatives across the world have applied crowdsourcing to contexts including constitutional reform, drafting federal bills, and generating local policies. However, crowd-civic systems also come with challenges and risks such as socio-technical barriers, marginalization of specific groups, silencing of interests, etc. Using a designthinking approach, this workshop will address both opportunities and challenges of crowd-civic systems to develop best practices for increasing public engagement with law and policy. The workshop organizers will suggest an …
