Description
Most people are experts in some area of information; however, they may not be knowledgeable about other closely related areas. How knowledge is generalized to hierarchically related categories was explored. Past work has found little to no generalization to categories closely related to learned categories. These results do not fit well with other work focusing on attention during and after category learning. The current work attempted to merge these two areas of by creating a category structure with the best chance to detect generalization. Participants learned order level bird categories and family level wading bird categories. Then participants completed multiple measures to test generalization to old wading bird categories, new wading bird categories, owl and raptor categories, and lizard categories. As expected, the generalization measures converged on a single overall pattern of generalization. No generalization was found, except for already learned categories. This pattern fits well with past work on generalization within a hierarchy, but do not fit well with theories of dimensional attention. Reasons why these findings do not match are discussed, as well as directions for future research.

Description
Recommendations made by expert groups are pervasive throughout various life domains. Yet not all recommendations--or expert groups--are equally persuasive. This research aims to identify factors that influence the persuasiveness of recommendations. More specifically, this study examined the effects of decisional cohesion (the amount of agreement among the experts in support of the recommendation), framing (whether the message is framed as a loss or gain), and the domain of the recommendation (health vs. financial) on the persuasiveness of the recommendation. The participants consisted of 1,981 undergraduates from Arizona State University. The participants read a vignette including information about the expert group making a recommendation--which varied the amount of expert agreement for the recommendation--and the recommendation, which was framed as either a gain or loss. Participants then responded to questions about the persuasiveness of the recommendation. In this study, there was a linear main effect of decisional cohesion such that the greater the decisional cohesion of the expert group the more persuasive their recommendation. In addition, there was a main effect of domain such that the health recommendation was more persuasive than the financial recommendation. Contrary to predictions, there was no observed interaction between the amount of decisional cohesion and the framing of the recommendation nor was there a main effect of framing. Further analyses show support for a mediation effect indicating that high levels of decisional cohesion increased the perceived entitativity of the expert group--the degree to which the group was perceived as a unified, cohesive group¬--which increased the recommendation's persuasiveness. An implication of this research is that policy makers could increase the persuasiveness of their recommendations by promoting recommendations that are unanimously supported by their experts or at least show higher levels of decisional cohesion.

Description
Advancing sustainable food systems requires holistic understanding and solutions-oriented approaches that transcend disciplines, so expertise in a variety of subjects is necessary. Proposed solutions are usually technically or socially oriented, but disagreement over the best approach to the future of food dominates the dialogue. Technological optimists argue that scientific advances are necessary to feed the world, but environmental purists believe that reductions in consumption and waste are sufficient and less risky. Life cycle assessment (LCA) helps resolve debates through quantitative analysis of environmental impacts from products which serve the same function. LCA used to compare dietary choices reveals that simple plant-based diets are better for the environment than diets that include animal products. However, analysis of soy protein isolate (SPI) demonstrates that certain plant-based proteins may be less preferable for the environment than some unprocessed meats in several categories due to additional impacts that come from industrial processing. LCAs' focus on production risks ignoring consumers, but the food system exists to serve consumers, who can be major drivers of change. Therefore, the path to a sustainable food system requires addressing consumption issues as well. Existing methods for advancing sustainable food systems that equate more information with better behavior or performance are insufficient to create change. Addressing food system issues requires sufficient tacit knowledge to understand how arguments are framed, what the supporting content is, the findings of primary sources, and complex and controversial dialogue surrounding innovations and interventions for food system sustainability. This level of expertise is called interactional competence and it is necessary to drive and maintain holistic progress towards sustainability. Development strategies for interactional competence are informed by studying the motivations and strategies utilized by vegans. A new methodology helps advance understanding of expertise development by assessing levels of expertise and reveals insights into how vegans maintain commitment to a principle that influences their daily lives. The study of veganism and expertise reveals that while providing information to debunk fallacies is important, the development of tacit knowledge is fundamental to advance to a stage of competence.

Description
Corporations in biomedicine hold significant power and influence, in both political and personal spheres. The decisions these companies make about ethics are critically important, as they help determine what products are developed, how they are developed, how they are promoted, and potentially even how they are regulated. In the last fifteen years, for-profit private companies have been assembling bioethics committees to help resolve dilemmas that require informed deliberation about ethical, legal, scientific, and economic considerations. Private sector bioethics committees represent an important innovation in the governance of emerging technologies, with corporations taking a lead role in deciding what is ethically appropriate or problematic. And yet, we know very little about these committees, including their structures, memberships, mandates, authority, and impact. Drawing on an extensive literature review and qualitative analysis of semi-structured interviews with executives, scientists and board members, this dissertation provides an in-depth analysis of the Ethics and Public Policy Board at SmithKline Beecham, the Ethics Advisory Board at Advanced Cell Technology, and the Bioethics Committee at Eli Lilly and offers insights about how ideas of bioethics and governance are currently imagined and enacted within corporations. The SmithKline Beecham board was the first private sector bioethics committee; its mandate was to explore, in a comprehensive and balanced analysis, the ethics of macro trends in science and technology. The Advanced Cell Technology board was created to be like a watchdog for the company, to prevent them from making major errors. The Eli Lilly board is different than the others in that it is made up mostly of internal employees and does research ethics consultations within the company. These private sector bioethics committees evaluate and construct new boundaries between their private interests and the public values they claim to promote. Findings from this dissertation show that criticisms of private sector bioethics that focus narrowly on financial conflicts of interest and a lack of transparency obscure analysis of the ideas about governance (about expertise, credibility and authority) that emerge from these structures and hamper serious debate about the possible impacts of moving ethical deliberation from the public to the private sector.

Description
Recently, it was demonstrated that startle-evoked-movements (SEMs) are present during individuated finger movements (index finger abduction), but only following intense training. This demonstrates that changes in motor planning, which occur through training (motor learning - a characteristic which can provide researchers and clinicians with information about overall rehabilitative effectiveness), can be analyzed with SEM. The objective here was to determine if SEM is a sensitive enough tool for differentiating expertise (task solidification) in a common everyday task (typing). If proven to be true, SEM may then be useful during rehabilitation for time-stamping when task-specific expertise has occurred, and possibly even when the sufficient dosage of motor training (although not tested here) has been delivered following impairment. It was hypothesized that SEM would be present for all fingers of an expert population, but no fingers of a non-expert population. A total of 9 expert (75.2 ± 9.8 WPM) and 8 non-expert typists, (41.6 ± 8.2 WPM) with right handed dominance and with no previous neurological or current upper extremity impairment were evaluated. SEM was robustly present (all p < 0.05) in all fingers of the experts (except the middle) and absent in all fingers of non-experts except the little (although less robust). Taken together, these results indicate that SEM is a measurable behavioral indicator of motor learning and that it is sensitive to task expertise, opening it for potential clinical utility.

Description
This paper examines the strength of a recent argument made against democracy. The notion of epistocracy, a system of government where the wise or the knowers rule, has garnered some attention of late. These theories of epistocracy have traditionally struggled with questions of political legitimacy and authority. In Against Democracy, Jason Brennan articulates an alternative theory for epistocracy which may prove more promising. Brennan argues instead that democracy faces objections of political legitimacy which epistocracy avoids because democracy either harms or violates rights as a result of granting political power to the incompetent. This negative argument against democracy hopes to make epistocracy the preferable option in comparison. I will argue, however, that if we take this comparative approach then we ought to prefer democracy---or, rather, democratic reform---over epistocracy as the best solution in addressing the concerns which Brennan raises. It is not enough to merely point to flaws in democracy. For this argument to be successful, it must also be shown that epistocracy avoids those flaws at an acceptable cost. I claim that, upon examination, epistocratic theories fail to make this case. Rather, it is evident from this examination that there are various institutional mechanisms available with which democracy may manage the risks and harms which might arise from imbuing the incompetent with political power. This in turn suggests ways by which we might reform democracy to achieve similar results hoped for by epistocrats without the effort, risk, and cost of tearing down and rebuilding our fundamental political institutions.

Description
With the help of some Information Measurement Theory (IMT), Kashiwagi Solutions Model (KSM), and deductive logic background, supply chain managers can start utilizing a new way to effectively and efficiently negotiate contracts. Developed by Dr. Dean Kashiwagi, the Best Value Approach has been 98% successful with over 1,800 projects for the past 20 years. The process gives vendors/suppliers the power to use their expertise. In return for not having to follow the rules set by the client/buyer, the vendor must show documentation and plans of risk management, value added processes, and metrics.

Description
The main purpose of this action research study was to understand the most appropriate methods to replicate expertise and expert performance in an ever-changing and dynamic global organization. It was also meant to empower team members in becoming more decisive experts within their respective fields/domains. In this study, ten (10) “snackable” videos were created to support microlearning on expertise. Interviews were conducted with experts across Microsoft spanning the United States, Latin America, and Europe. Using knowledge management theory, deliberate practice, and organizational learning theory helped create the framework. Phenomenological inquiry, narrative inquiry, and digital storytelling supported the enactment of the study. The Expert-to-Expert Practice Framework (E2EPF) is a capability that was created to connect outsider knowledge with internal requirements using sensemaking, knowledge creation, and team building. It was developed to address the many challenges of building and fostering expertise within a hybrid workplace. The study was conducted during a six-month period starting from March 2022 to September 2022. Ten Microsoft experts, six team members, and one leader participated in this study that included interviews, expert panel discussions, surveys, and the development of the next generation of expert profiles. The qualitative data from this study provides a much richer understanding of the phenomenon of expertise within a global workplace. Insider experts identified that the E2EPF was able to create a differentiated experience for their practice within a relatively short time frame. Four phenomenological themes and the essence of expertise emerged from the data which indicates the effective utilization of the practice framework.

Description
Northeastern Arizona has experienced a recent increase in helium extraction activity. This qualitative case study articulates and explores various sociotechnical imaginaries – or, collectively produced social justifications for technological decisions and systems – that inform this new stage of underground helium extraction. Leveraging two years of interviews, document analysis, and participant observations to understand and interrogate the political and cultural origins of perceptions around helium extraction, I examined how these imaginaries and associated power dynamics influenced communication within and between stakeholder groups. In order to mitigate the power differentials between stakeholder groups, and put these imaginaries in conversation with each other, I led the development of a series of short videos that explain controversial technoscientific concepts from this research. These videos were produced in continuous collaboration with multiple disparate stakeholders, including activists, regulators, and industry members, in order to create a space for a productive conversation and reflection to explore tensions between conflicting points of view between stakeholders. This iterative work used the imaginaries of helium extraction in Arizona to produce a space for collective deliberation that can result in negotiated shared knowledge through brokered dialogue amongst these disparate groups and their competing visions of Arizona’s helium futures.

Description
This dissertation explores the technolinguistic brokering experience of adolescents and (im)migrant non-English speaking mothers in acculturating families. By focusing on the performance of cultural intermediation, I examine the dimensions of technolinguistic brokering and their influence upon the Adolescent Language Technology Broker (ALTB) and mother relationship. Additionally, I explore the factors of power present as a result of the complexities of the ALTBs role to connect their mother to the English speaking community. This research uses a qualitative approach to explore concepts of expertise, knowledge, (inter)dependence, relational maintenance and quality, and power in the dialogic cultural relationship. Research indicates that expertise in the form of culture, cultural interactions, multilingual, and relational maintenance and quality contribute to the ALTBs capabilities in building cultural relationships. Moreover, to assist in dealing with power tensions created by differing levels of expertise and knowledge, ALTBs and mothers communicatively construct an (inter)dependent cultural relationship. I highlight practical implications, discuss limitations, and provide recommendations for future directions.
