Leveraging Mixed Expertise in Crowdsourcing.

Crowdsourcing systems promise to leverage the "wisdom of crowds" to help solve many kinds of problems that are difficult to solve using only computers. Although a crowd of people inherently represents a diversity of skill levels, knowledge, and opinions, crowdsourcing system designers typically view this diversity as noise and effectively cancel it out by aggregating responses. However, we believe that by embracing crowd workers' diverse expertise levels, system designers can better leverage that knowledge to increase the wisdom of crowds. In this thesis, we propose solutions to a limitation of current crowdsourcing approaches: not accounting for a range of expertise levels in the crowd. The current body of work in crowdsourcing does not systematically examine this, suggesting that researchers may not believe the benefits of using mixed expertise warrants the complexities of supporting it. This thesis presents two systems, Escalier and Kurator, to show that leveraging mixed expertise is a worthwhile endeavor because it materially benefits system performance, at scale, for various types of problems. We also demonstrate an effective technique, called expertise layering, to incorporate mixed expertise into crowdsourcing systems. Finally, we show that leveraging mixed expertise enables researchers to use crowdsourcing to address new types of problems.PhDComputer Science and EngineeringUniversity of Michigan, Horace H.

A Multi-Dimensional Approach for Framing Crowdsourcing Archetypes

All different kinds of organizations – business, public, and non-governmental alike – are becoming aware of a soaring complexity in problem solving, decision making and idea development. In a multitude of circumstances, multidisciplinary teams, high-caliber skilled resources and world-class computer suites do not suffice to cope with such a complexity: in fact, a further need concerns the sharing and ‘externalization’ of tacit knowledge already existing in the society. In this direction, participatory tendencies flourishing in the interconnected society in which we live today lead ‘collective intelligence’ to emerge as key ingredient of distributed problem solving systems going well beyond the traditional boundaries of organizations. Resulting outputs can remarkably enrich decision processes and creative processes carried out by indoor experts, allowing organizations to reap benefits in terms of opportunity, time and cost. Taking stock of the mare magnum of promising opportunities to be tapped, of the inherent diversity lying among them, and of the enormous success of some initiative launched hitherto, the thesis aspires to provide a sound basis for the clear comprehension and systematic exploitation of crowdsourcing. After a thorough literature review, the thesis explores new ways for formalizing crowdsourcing models with the aim of distilling a brand-new multi-dimensional framework to categorize various crowdsourcing archetypes. To say it in a nutshell, the proposed framework combines two dimensions (i.e., motivations to participate and organization of external solvers) in order to portray six archetypes. Among the numerous significant elements of novelty brought by this framework, the prominent one is the ‘holistic’ approach that combines both profit and non-profit, trying to put private and public sectors under a common roof in order to examine in a whole corpus the multi-faceted mechanisms for mobilizing and harnessing competence and expertise which are distributed among the crowd. Looking at how the crowd may be turned into value to be internalized by organizations, the thesis examines crowdsourcing practices in the public as well in the private sector. Regarding the former, the investigation leverages the experience into the PADGETS project through action research – drawing on theoretical studies as well as on intensive fieldwork activities – to systematize how crowdsourcing can be fruitfully incorporated into the policy lifecycle. Concerning the private realm, a cohort of real cases in the limelight is examined – having recourse to case study methodology – to formalize different ways through which crowdsourcing becomes a business model game-changer. Finally, the two perspectives (i.e., public and private) are coalesced into an integrated view acting as a backdrop for proposing next-generation governance model massively hinged on crowdsourcing. In fact, drawing on archetypes schematized, the thesis depicts a potential paradigm that government may embrace in the coming future to tap the potential of collective intelligence, thus maximizing the utilization of a resource that today seems certainly underexploited

The Anesthesia Continuing Education Market and the Value Creation From a Sustainable Unified Platform

Practicing anesthesia professionals in the United States are all governed by various profession-specific regulatory bodies that mandate continuing education (CE) requirements. To date, no unified resource exists for anesthesia professionals (i.e., Anesthesiologists, Certified Registered Nurse Anesthetists, and Anesthesiologist Assistants) to explore the CE offerings available within the marketplace. This study endeavored to convey the potential value of a unified anesthesia CE resource. It investigated how to cultivate a sustainable platform to potentially improve how anesthesia professionals search available CE offerings and to potentially enhance how anesthesia CE providers reach anesthesia professionals. This qualitative study was conducted utilizing an integrative review of the literature. The key concepts identified and investigated were network effect, segmentation, first to market, best of breed, search costs, transaction costs, minimally viable product, evolutionary phases of platforms, platform theory, platform business model, platform economy, and types of platforms. Inductive content analysis was chosen as the organizational method for the resultant qualitative data. The goal of the analysis was to create a conceptual, practical, and strategically applicable platform paradigm for the anesthesia CE marketplace driven by the insights and amalgamations from the literature. The analyzed concepts, dimensions, and indicators of platform successes and their applications potentially facilitate anesthesia professionals’ CE explorations and CE providers’ marketing efforts, as well as contextualize the overarching impacts and implications onto the anesthesia CE industry and beyond. The conclusion portrays these impacts and implications

Hajj crowd management via a mobile augmented reality application: a case of The Hajj event, Saudi Arabia

Hajj event is considered as one of the Islamic pillars that each Muslim, who could afford its’ expenses and are well bodied, should perform its’ rituals at least once in a lifetime. Therefore, they could travel to Mecca city, in the Kingdom of Saudi Arabia to perform Hajj rituals. This holy city hosts this event annually in the last month of the Arabic calendar, which is Dhul Hijjah, and it lasts for 6 days. In addition, those Muslim visitors or pilgrims are obligated to be accommodated at Hajj ritual places, which are Arafat, Mina and Muzdalifah. However, in the last ten years, it was noticed that the Hajj events are crowded every year. Therefore, Hajj crowd management is being a complex task, due to the huge number of the pilgrims as they are crowded at the Hajj ritual places. This huge number is causing many problems, and Hajj authorities are facing difficulties in managing those crowded pilgrims. As a result, this research focuses on three main problems that occur at Hajj events. First, difficulties in organizing the crowds’ movements of the pilgrims, as Hajj events host enormous number of pilgrims in limited geographical spaces at the ritual places. This problem leads to overcrowdings, congestions and stampedes. Second, the pilgrims could get lost at Hajj ritual places, especially when they are moving between these places. Third, lack of directional information and guidance for those lost pilgrims. This problem leads to difficulties in finding their groups at the ritual sites, because the huge number of the pilgrims. Thus, this research proposes to deploy a technology, such as a Mobile Augmented Reality application. This application would assist the Hajj authorities (staff and operators) in managing the pilgrims’ movements between the ritual places, and to provide directions to the lost pilgrims. In addition, it would help those lost pilgrims by alerting, and sending their location information to their group guide. On the other hand, the research literature review covers previous studies about the Hajj crowd management, as it is divided into two perspectives. The theoretical perspective, which explains the crowd management steps that should be followed and applied, as these steps would help the Hajj authorities to succeed in crowd management at Hajj events. The practical perspective presents some studies that are related to the Hajj events. Those studies offered some solutions to manage crowded pilgrims, to avoid overcrowdings and stampedes, and to identify, locate and guide lost pilgrims. The solutions were Radio Frequency Identification (RFID) systems, Global Positioning Systems (GPS) deceives and monitoring cameras. In addition, this research conducted and distributed questionnaires on 104 respondents. They were selected as they are related to Hajj events. The results of this research method confirmed that the Hajj events face problems. For example, overcrowdings, congestions and stampedes that occur at the ritual places, due to lack of pilgrims organization in limited spaces at these places. In addition, foreign pilgrims face difficulties in guidance, due to lack of directional information, and they could get lost from their groups at the Hajj events. In addition, the respondents suggested using technology to assist Hajj authorities in Hajj crowd management. Therefore, deploying MAR application is suggested, as a solution to solve or at least reduce the Hajj problems. The proposed application could help the Hajj authorities to manage the crowded pilgrims at the Hajj ritual places as this research illustrates two scenarios in Hajj crowd management. In conclusion, this application is beneficial and significant in crowd management at Hajj events, as it could provide instant information using high-speed process in sending and receiving information. In addition, the information about the pilgrims’ movements could be gathered, presented on smart devices and shared between applications’ users. Those users will be the Hajj staff on the ground and the Hajj operators in the control room of Hajj operations

THE NEW ENTREPRENEURIAL LANDSCAPE AND THE VALUE CO-CREATION PROCESS: THE ROLE OF THE CROWD IN THE PRE-PURCHASE CROWDFUNDING

The entrepreneurial finance landscape is changing very rapidly (Block, Colombo, Cumming, Vismara, 2018). New players have emerged, with a determinant contribution of the technological revolution. The resources interplay in the peer-to-peer business and network has led to the development of new financing instruments able to boosting innovation and the creation of new ventures. Social and economic innovation is searching new ways to emerge; this requires new models for interpreting the enlarged notion of value in the crowd/entrepreneurs relationship. Despite the rapid growth of alternative finance, the academic literature on crowdfunding as a new financing model able to reduce financing constraints for firms, still lack evidence whether and how these new players and their investment approach are transforming the entrepreneurial landscape. In particular, the reference is to the complex mix of economic and social expectations deriving from the participation to the pre-purchase crowdfunding mechanism. Findings from the explorative study suggest that the pre-purchase mechanism is leading to the configuration of new market niches, where supporters act as an informed investor and consumers. Additionally, the joint value created by the efforts made by entrepreneurs and the crowd, creates sounder positive externalities, those favor growth possibilities to survive of the new ventures
