Eliciting information from adults: quality, quantity, and their willingness to disclose to an avatar interviewer

Avatars—digital representations of humans—may be a useful tool in a wide range of areas, such as education, advertising, communication, and health. The overarching goal of the present research was to examine the use of avatars in the context of evidential and clinical interviewing, in the hope that this novel technology could facilitate adults’ memory performance and enhance their disclosure of sensitive information. The first specific aim was to examine the effectiveness of an avatar interviewer on adults’ accounts of a witnessed event. In this context, adults were interviewed by either a digital-human avatar or a human face-to-face using both free- and directed-recall questions. Some participants also received post-event misinformation that was presented by either the digital-human avatar or the human interviewer. In addition, I examined the impact of several individual differences, including participants’ level of autism and personality traits, and their perception of the avatar’s operation. Finally, I investigated the effectiveness of avatar interviewers with varying degrees of anthropomorphism on adults’ accounts. The second specific aim was to explore the potential for avatar professionals in the context of the disclosure of sensitive information. In the present thesis, I investigated the effects of two types of avatar interviewers: a more anthropomorphic, 2D cartoon-rendered digital-human avatar, and a less anthropomorphic, speech-wave avatar. The digital-human avatar resembled the appearance of the human interviewers who were also used in the present research, but the avatar’s movement was restricted to eye blinks and head tilts. The speech-wave avatar interviewer resembled Apple’s Siri. Both types of avatar were voiced and operated by a concealed human interviewer. The digital-human avatar’s lips moved in synchrony with the human’s speech; the speech-wave avatar moved up and down, also in synchrony with the human’s speech. The avatar was displayed on a computer monitor that was placed on a table directly in front of the participant. The interviews involving the human interviewer were conducted face-to-face. Overall, differences in participants’ memory performance was not detected when they were interviewed only once by either a digital-human avatar or a human interviewer. When participants were interviewed twice, on the other hand, participants who were interviewed by the human interviewer were more talkative and provided more correct details than did participants who were interviewed by the digital-human avatar, but their reports were also less accurate during free recall. Still, the digital-human avatar did not protect the participants from the adverse effects of misleading information. Finally, relative to an interview with the digital-human avatar, participants’ memory performance was enhanced when the speech- wave avatar interviewed them. In addition to these group-level results, participants with low conscientiousness and autism traits, or who perceived the digital-human avatar as computer- operated, were more accurate in their accounts during free recall when a digital-human avatar interviewed them. With respect to disclosure, overall, participants preferred to disclose information to a human professional face-to-face rather than to avatar professionals. When I compared the digital-human avatar to the speech-wave avatar, participants preferred to disclose more embarrassing information, particularly sex-related topics, and reported more coherent details about an embarrassing personal event to a speech-wave avatar. In terms of the avatar’s characteristics, participants indicated that they would be more comfortable disclosing embarrassing information to an avatar appearing as a female around 45- to 54-years of age. Collectively, my findings provide initial insight of the potential value and pitfalls of using avatars in evidential and clinical interviewing. In this day and age, humans may have adapted to technology, treating non-human interviewers in much the same way as they treat human interviewers. Still, there is a place for avatars in specific populations, and in the context of disclosing stigmatising experiences. The results of the present research have important implications for designing and using avatars that might aid humans in performing specific tasks in help-seeking settings

Silicon Microring Resonator Driven by High-Mobility Conductive Oxide Capacitor

Silicon photonics has rapidly become one of the most promising photonic integration platforms. Especially, microring resonator (MRR) plays a pivotal role in silicon photonics and has been widely used for electro-optic (E-O) modulators and wavelength filters due to its small footprint, low energy consumption, and high quality factor (Q-factor). Recently, indium-tin-oxide (ITO) has emerged as a new material that can be integrated with silicon MRRs using a metal-oxide-semiconductor (MOS) structure, which can offer significantly enhanced E-O effect and better energy efficiency. However, the performance is limited by the relatively low electron mobility, which induces relatively high optical loss and degrades Q-factor. This thesis focuses on the demonstration of high Q-factor MRR driven by high mobility transparent conductive oxide (TCO) material. In the first part, a passive MRR is optimized by fabrication and theoretical design, which achieves a high Q-factor of 20,000. Next, a MRR with a titanium-doped indium oxide gate has been demonstrated to obtain a tunability of 42 pm/V with a high Q-factor above 3,600. Besides, a new method has been developed to characterize the optical frequency free carrier mobility in the accumulation layer of the MOS structure. At the end of the thesis, different MRRs driven by high mobility TCO materials are compared. The simulation results indicate that an ultra-high tunability of 906 pm/V and a high Q-factor above 6,700 can be potentially achieved with slotted waveguide MRR

Performance-based Fire Safety Design for Existing Small-scale Hospitals

AbstractThe new era of National Health Insurance in 2000 has had a significant impacted on the management and operation of smallscale hospitals. In response to social needs, and in order to survive under the new insurance system, some small-scale hospitals have transformed or established new Respiratory Care Wards by using existing hospital space. According to the 2009 statistics released by Department of Health, Executive Yuan, there are a total of 307 small-scale medical institutes which provide servicesunder 99 beds. Compared with other large-scale medical centers and general hospitals, small-scale hospitals cannot properly deal with safety management and response to emergency evacuation due to lack of facilities, equipment and human resources. Therefore, small-scale hospitals face a major challenge in emergency response once a fire has occurred. As a result of such a situation, this study has focused mainly on Respiratory Care Wards (RCW) where patients are unable to evacuate. It hopes to analyse the safety management, and emergency response in small-scale hospitals by means of understanding the space characteristics and fire risk. Through on-site surveys, we can understand the fire risk, space features, patient characteristics, facilities and equipment. With reference to the related regulations of hospital emergency management and response, we will propose some fire safety engineering approaches, such as refuge areas in horizontal evacuation and so-called “besieged zones” for “defense-in-place”, etc., to provide some alternative measures to improve fire safety for those small-scale hospitals

Space Net Optimization

Most metaheuristic algorithms rely on a few searched solutions to guide later searches during the convergence process for a simple reason: the limited computing resource of a computer makes it impossible to retain all the searched solutions. This also reveals that each search of most metaheuristic algorithms is just like a ballpark guess. To help address this issue, we present a novel metaheuristic algorithm called space net optimization (SNO). It is equipped with a new mechanism called space net; thus, making it possible for a metaheuristic algorithm to use most information provided by all searched solutions to depict the landscape of the solution space. With the space net, a metaheuristic algorithm is kind of like having a ``vision'' on the solution space. Simulation results show that SNO outperforms all the other metaheuristic algorithms compared in this study for a set of well-known single objective bound constrained problems in most cases.Comment: 12 pages, 6 figure

Effect of Post Heated TiN Coating on Pitting Corrosion of Austenitic Stainless Steel

This study used cathodic arc deposition technique to coat TiN film on 316L austenitic stainless steel, and then the coated specimens were heat-treated at the different temperatures. Observation of coating morphology and corrosion tests were conducted for exploring the effect of post-heating temperature on composition, microstructure, and corrosion behavior of the coatings. The results showed when the heating temperature was up to the range of 500-600 oC, a Ti-N-O mixed film consisting of the two TiO2 and TiN phases was formed on the outer layer. Particular, the film heated at 500 oC had a dense structure as well as homogeneous chemical composition. Such the result could effectively inhibit pitting corrosion of 316L stainless steel in 3.5 wt% NaCl and 10 vol% HCl solutions

Apoptosis Induction in Primary Human Colorectal Cancer Cell Lines and Retarded Tumor Growth in SCID Mice by Sulforaphane

We have investigated the anticancer effects of the dietary isothiocyanate sulforaphane (SFN) on colorectal cancer (CRC), using primary cancer cells lines isolated from five Taiwanese colorectal cancer patients as the model for colorectal cancer. SFN-treated cells accumulated in metaphase (SFN 6.25 μM) and subG1 (SFN 12.5 and 25 μM) as determined by flow cytometry. In addition, treated cells showed nuclear apoptotic morphology that coincided with an activation of caspase-3, and loss of mitochondrial membrane potential (ΔΨm). Incubations at higher SFN doses (12.5 and 25 μM) resulted in cleavage of procaspase-3 and elevated caspase-2, -3, -8, and -9 activity, suggesting that the induction of apoptosis and the sulforaphane-induced mitosis delay at the lower dose are independently regulated. Daily SFN s.c. injections (400 micromol/kg/d for 3 weeks) in severe combined immunodeficient mice with primary human CRC (CP1 to CP5) s.c. tumors resulted in a decrease of mean tumor weight by 70% compared with vehicle-treated controls. Our findings suggest that, in addition to the known effects on cancer prevention, sulforaphane may have antitumor activity in established colorectal cancer

Giant lipoma arising from deep lobe of the parotid gland

BACKGROUND: Lipomas are common benign soft tissue neoplasms but they are found very rarely in the deep lobe of parotid gland. Surgical intervention in these tumors is challenging because of the proximity of the facial nerve, and thus knowledge of the anatomy and meticulous surgical technique are essential. CASE PRESENTATION: A 71-year-old female presented with a large asymptomatic mass, which had occupied the left facial area for over the past fifteen years, and she requested surgical excision for a cosmetically better facial appearance. The computed tomography (CT) scan showed a well-defined giant lipoma arising from the left deep parotid gland. The lipoma was successfully enucleated after full exposure and mobilization of the overlying facial nerve branches. The surgical specimen measured 9 × 6 cm in size, and histopathology revealed fibrolipoma. The patient experienced an uneventful recovery, with a satisfying facial contour and intact facial nerve function. CONCLUSION: Giant lipomas involving the deep parotid lobe are extremely rare. The high-resolution CT scan provides an accurate and cost-effective preoperative investigative method. Surgical management of deep lobe lipoma should be performed by experienced surgeons due to the need for meticulous dissection of the facial nerve branches. Superficial parotidectomy before deep lobe lipoma removal may be unnecessary in selected cases because preservation of the superficial lobe may contribute to a better aesthetic and functional result
