Individual-Technology Fit: Matching Individual Characteristics and Features of Biometric Interface Technologies with Performance
Abstract INDIVIDUAL-TECHNOLOGY FIT: MATCHING INDIVIDUAL CHARACTERISTICS AND FEATURES OF BIOMETRIC INTERFACE TECHNOLOGIES WITH PERFORMANCE By ADRIANE B. RANDOLPH MAY 2007 Committee Chair: Dr. Melody Moore Jackson Major Department: Computer Information Systems The term biometric literally means “to measure the body”, and has recently been associated with physiological measures commonly used for personal verification and security applications. In this work, biometric describes physiological measures that may be used for non-muscularly controlled computer applications, such as brain-computer interfaces. Biometric interface technology is generally targeted for users with severe motor disabilities which may last long-term due to illness or injury or short-term due to temporary environmental conditions. Performance with a biometric interface can vary widely across users depending upon many factors ranging from health to experience. Unfortunately, there is no systematic method for pairing users with biometric interface technologies to achieve the best performance. The current methods to accommodate users through trial-and-error result in the loss of valuable time and resources as users sometimes have diminishing abilities or suffer from terminal illnesses. This dissertation presents a framework and methodology that links user characteristics and features of biometric interface technologies with performance, thus expediting the technology-fit process. The contributions include an outline of the underlying components of capturing and representing individual user characteristics and the impact on the performance of basic interaction tasks using a methodology called biometric user profiling. In addition, this work describes a methodology for objectively measuring an individual’s ability to control a specific biometric interface technology such as one based on measures of galvanic skin response or neural activity. Finally, this work incorporates these concepts into a new individual-technology fit framework for biometric interface technologies stemming from literature on task-technology fit. Key words: user profiles, biometric user profiling, biometric interfaces, fit, individual-technology fit, galvanic skin response, functional near-infrared, brain-computer interfaceDoctor of Philosophy (PhD)Computer Information System
Understanding the Potential of Augmented Reality in Manufacturing Environments
Manufacturing companies are confronted with challenges due to increasing flexibility requirements and skill gaps. Augmented Reality applications offer an efficient way to overcome these tensions by enhancing the interaction between people and technology. The positive effects of Augmented Reality solutions are often described in individual models in the scientific literature. This research-in-progress aims to aggregate the empirical findings in the usage of Augmented Reality solutions in manufacturing environments. A meta-analysis is conducted to synthesise several small studies into one large study to achieve this. In particular, the meta-analysis will focus on the impact of Augmented Reality applications on cognitive load levels. Furthermore, the effect on processing time and error rates will be evaluated. Initial results of the meta-analysis will be expected and reported at this year’s NeuroIS Retreat.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Economics of Technology and InnovationSystem Engineerin
Anthia's tales, Embedded Narratives in Xenophon of Ephesus' Ephesika
Although Xenophon of Ephesus is considered as an author with relatively few literary merits, he stands out for his skill in composing embedded narratives, stories within the main story playing an important role in the action's development. The purpose of this paper is to examine how the author takes advantage of this secondary narratives particularly regarding a singular character, namely, Anthia, the Ephesiaka's heroine, Anthia, who is at once narrator and subject of narratives contained within the novel's major framing narrative. I sustain that such strategy is carried out in a close intertextual connection to the Odyssey and contributes to her characterization as a woman specially endowed for rhetoric and cunning.Dentre os autores do romance grego antigo, Xenofonte de Éfeso é considerado o menos habilidoso em vista do estilo. No entanto, destaca-se enquanto narrador pelo emprego que faz das narrativas intercaladas, histórias embutidas no quadro mais amplo do romance. Esse artigo propõe-se a examinar o emprego desse recurso relacionando-o com Antia, que é a uma só vez narradora e objeto de narrativa intercalada em Efesíacas. Argumenta-se que a estratégia promove a intertextualidade com a Odisseia e contribui para caracterização da personagem como dotada de habilidade retórica e astúcia.Fil: Silva Duarte, Adriane da.

Developing Soft Skills to Manage User Expectations in IT Projects: Knowledge Reuse among IT Project Managers
This research explores information technology (IT) project managers\u27 reuse of knowledge associated with soft skills when managing user expectations. Through interviews with IT project managers, several themes emerged: novelty of problems, conditions within the organization, types of available knowledge, and methods for reusing knowledge. Within this study, we discovered the need for additional research on how social norms and organizational conditions encourage or inhibit knowledge reuse. Furthermore, we identified a difference in the usefulness of knowledge captured in formal repositories according to levels of project management experience. The findings confirm, extend, and illuminate the current research associated with knowledge reuse in IT project management.

A qualidade de vida em idosos usuários de próteses auditivas com adaptação aberta e retroauriculares
TCC(graduação) - Universidade Federal de Santa Catarina. Centro de Ciências da Saúde.Fonoaudiologia.Introdução: A audição exerce grande influência na qualidade de vida do idoso, e visando melhorar a sua capacidade comunicativa, faz-se necessária a reabilitação desta capacidade, por meio do uso da prótese auditiva. Visando atender, minimizar e suprir as necessidades de indivíduos com perda auditiva de configuração descendente, no caso da presbiacusia, foi desenvolvido um novo modelo para a adaptação da prótese auditiva conhecido como adaptação aberta. Este modelo de prótese não necessita da utilização de molde auricular e o som é transmitido ao meato acústico externo através de um micro-tubo acoplado a uma pequena oliva. A literatura recomenda a utilização de medidas subjetivas, como questionários para entender o processo de adaptação com as próteses auditivas. O questionário WHOQOL-bref tem sido recomendado para avaliar a qualidade de vida e tem sido utilizado mundialmente, pois foi criado dentro de uma escala com perspectiva transcultural. Objetivo: Comparar a qualidade de vida dos idosos usuários de próteses auditivas retroauriculares com os usuários de próteses auditivas com adaptação aberta. Metodologia: Participaram deste estudo 12 idosos, com faixa etária de 60 a 82 anos, sendo seis do gênero masculino e seis do gênero feminino. Em relação ao tipo de adaptação sete foram adaptados com próteses retroauriculares s e cinco com próteses mini-retroauriculares com tubo fino e oliva aberta. A pesquisa foi realizada em dois Serviços de Atenção à Saúde Auditiva e duas empresas particulares localizadas na cidade de Florianópolis. Foram entrevistados idosos entre seis meses e um ano após a adaptação das próteses auditivas, sendo aplicado o questionário Abreviado de Avaliação da Qualidade de Vida (WHOQOL-bref) e questionário de uso e manutenção da prótese auditiva realizado pela própria autora. Resultados: Verificou-se que os usuários de próteses auditivas retroauriculares e com adaptação aberta apresentaram, os respectivos resultados, por domínio avaliado do WHOQOL-bref: físico 62,76 e 74,29; psicológico 65,1 e 76,39, relações sociais 63,1 e 75,00, meio ambiente 64,95 e 70,63. Em relação ao gênero, as mulheres apresentam os seguintes resultados: físico 74,4, psicológico 76,39, relações sociais 72,22 e meio ambiente 72,4. Já os homens apresentaram os respectivos resultados: físico 63,54, psicológico 65,28, relações sociais 65,28 e meio ambiente 65,28. Conclusão: Foi possível concluir que os idosos usuários de prótese auditiva com adaptação aberta apresentaram uma melhor qualidade de vida em todos os domínios avaliados, que os idosos usuários de prótese auditiva retroauricular.Introduction: Hearing has great influence on the quality of life of the elderly, and to improve their ability to communicate, it is necessary rehabilitation of this capability through the use of hearing aids. Seeking to assist, minimize and fulfill the needs of individuals with downward-sloping hearing loss, in the case of presbycusis a new model of hearing aid fitting known as open fit has been developed. This hearing aid model does not require the use of ear mold and the sound is transmitted to the ear canal through a micro-tube attached to a small olive. The literature recommends the use of subjective measures such as questionnaires to understand the adaptation process of hearing aids. The WHOQOL-BREF questionnaire has been recommended to assess the quality of life and has been used worldwide, since it was created in a scale with cross-cultural perspective. Objective: To compare the quality of life of elderly who are BTE hearing aid users with open fit hearing aid users. Methodology: The study included 12 elderly, aged between 60-82 years, six males and six females. Regarding the type of adaptation, seven BTE hearing aids and five mini-BTE hearing aids with slim tube and open olive were fitted. The research was conducted in two Hearing Health Care Services and two private companies located in the city of Florianópolis. Respondents were interviewed between six months and one year after the hearing aid fitting, trough the WHO Quality of Life questionnaire (WHOQOL-bref) and the “Use and Maintenance of Hearing Aids” questionnaire developed by the author. Results: It was found that BTE hearing aids users and open fit BTE users presented the following results for each domain of WHOQOL-BREF: physical health 62,76 - 74,29; psychological 65,1 - 76,39, social relationship 63,1 - 75,00, environment 64,95 - 70,63. Regarding gender, women showed as results: physical 74,4, psychological 76,39, social relationships 72,22 and environment 72,4. In contrast, men presented their results: physical health 63,54, psychological 65,28, social relationships 65,28 and environment 65,28. Conclusion: It was concluded that the elderly users of open fit hearing aids users presented better quality of life in all domains assessed when compared to regular BTE hearing aids

Individual Characteristics and Their Effect on Predicting Mu Rhythm Modulation
Brain-computer interfaces (BCIs) offer users with severe motor disabilities a nonmuscular input channel for communication and control but require that users achieve a level of literacy and be able to harness their appropriate electrophysiological responses for effective use of the interface. There is currently no formalized process for determining a user\u27s aptitude for control of various BCIs without testing on an actual system. This study presents how basic information captured about users may be used to predict modulation of mu rhythms, electrical variations in the motor cortex region of the brain that may be used for control of a BCI. Based on data from 55 able-bodied users, we found that the interaction of age and daily average amount of hand-and-arm movement by individuals correlates to their ability to modulate mu rhythms induced by actual or imagined movements. This research may be expanded into a more robust model linking individual characteristics and control of various BCIs.

Superteam Transactions: The Effect of an Intelligent Assistant in Virtual Teams
The 2020 Deloitte Global Human Capital Trends report identifies emerging advancements in artificial intelligence (AI) that are enabling humans and machines to interact in new ways (Deloitte Institute, 2020). Deloitte uses the term “superteams†to represent the integration of AI into teams. Examples of such interactions include the use of AI in a project at Microsoft to analyze and organize data that are then used to create knowledge networks for team members (Deloitte Institute, 2020). In many instances, the integration of AI into teams has taken the form of an intelligent assistant that provides relevant information when needed by aiding in knowledge sharing, application, and collaboration. Opus Research refers to 2021 as “The Year of the Ubiquitous Intelligent Assistants†noting that the use of intelligent assistants in businesses has grown significantly due to the Covid-19 pandemic (Miller, 2021). As a result, organizations have expanded the use of intelligent assistants in virtual teams. Team performance among virtual team members is dependent upon the sharing and application of knowledge during the execution of work. Virtual teams are in a unique position relative to knowledge sharing and application since they rarely, if ever, meet face-to-face and rely upon technology-mediated communications. Temporal, geographical, and cultural differences serve to create barriers to knowledge sharing and, thus, the effective application of knowledge when needed (Kanawattanachai & Yoo, 2007; Sarker, Sarker, Nicholson, & Joshi, 2005). Understanding the impact of knowledge sharing and application among virtual teams involves socio-cognitive processes. Transactive memory theory, developed by Wegner (1986), is based on the view that individuals serve as external memory aids for other individuals. Individuals thus depend upon each other to remember specific knowledge domains (Kanawattanachai & Yoo, 2007). A transactive memory system (TMS) develops among team members based on a shared understanding of who knows what within the group. Kanawattanachai and Yoo (2007) demonstrate that virtual teams with developed TMS can effectively coordinate tasks and knowledge among team members. In their study, virtual teams developed TMS over an extended time, such that performance improvements began to manifest in eight weeks. Specifically, this research seeks to understand (1) What is the impact of an intelligent assistant\u27s relationship between transactive memory systems and knowledge sharing within virtual teams?; (2) What is the impact of an intelligent assistant\u27s relationship between transactive memory systems and knowledge application within virtual teams? Our research extends the Choi et al. (2010) research model with the Bachrach et al. (2019) concept of an antecedent team member with special characteristics, an intelligent assistant. We seek to understand how the intelligent assistant team member contributes to the transactive memory system and knowledge sharing and application among all virtual team members. We plan to distribute a survey to teams who are using an intelligent assistant to understand these interactions and influences in the knowledge sharing and application processes
