Discursive Formations and Authority in Henry James’s Washington Square

( Billie Pritchett ) 경남대학교 인문과학연구소 2024 人文論叢 Vol.63 No.-

Using a Foucauldian-Lacanian framework, this paper examines how the father figure in Henry James’s Washington Square ([1880] 1881) deploys nineteenth-century legal and medical discursive formations to justify patriarchal authority. The father figure, American physician Doctor Austin Sloper, bars his daughter Catherine’s marriage to suitor Morris Townsend, claiming both patriarchal right and privileged diagnostic knowledge about human personality. This essay argues that Sloper’s circumscription of his daughter’s freedom and judgments about personality result from a system of rationalization based on popular discursive formations derived from the burgeoning urban landscape of nineteenth-century America, and that these discourses permit Sloper as scientist and patriarch to justify his prejudices and extend power over his daughter as the subject supposed to know.

Teacher Play Interaction Styles : Effects on Play Behavior and Relationships with Teacher Training and Experience

Billie Enz,James F . Christie 한국유아교육학회 1997 INTERNATIONAL JOURNAL OF EARLY CHILDHOOD EDUCATION Vol.2 No.1

This study examined how four preschool teachers, who differed greatly in terms of experience and training, interacted with children during play. Over the course of three months, each teacher was videotaped interacting with three groups of children. The teachers were taped twice with each group. The videotaped play sessions were then transcripted and analyzed. Six different play interaction styles were identified: uninvolved, interviewer, stage manager, co-player, player leaders and director. The stage-manager, co-player and play leaders styles appeared to have a positive impact on children‘s pretend play, whereas the uninvolved, interviewer and director styles impeded children‘s play efforts. The teachers‘ differences in training and experience paralleled their choice of play styles. The two most experienced teachers relied heavily on the three effective styles, while the two inexperienced teachers consistently used less effective styles.

Relationships between Creative Thinking and Problem Solving Styles among Secondary School Students

Billie L. Woodel-Johnson,Marcia Delcourt,Donald J. Treffinger 대한사고개발학회 2012 The International Journal of Creativity & Problem Vol.22 No.2

This study’s primary purposes were to explore relationships between creative thinking abilities and problem-solving styles among high school students and to provide additional evidence relating to the ongoing inquiry and discussion regarding “level and style” in assessing creativity. The 105 participants had a mean age of 16.2 and were enrolled in three high schools with similar demographics and academic offerings. Results of the correlational analyses indicated no significant relationships between creative thinking and problem solving style variables. These findings provide evidence supporting the independence of level and style in the assessment of creativity.

DNA sequence-dependent enhancement of Cy3 fluorescence

Harvey, Billie Jo,Perez, Claudia,Levitus, Marcia Korean Society of Photoscience 2009 Photochemical & photobiological sciences Vol.8 No.8

Cyanine dyes are extensively used as fluorescent probes in molecular biology, biochemical and biophysical applications. We investigated the fluorescent properties of Cy3 covalently attached to the 5' terminus of DNA oligonucleotides, and demonstrated that its fluorescence efficiency and lifetime depend strongly on DNA sequence. DNA sequence determines the extent and nature of the interactions between the dye and the DNA bases, which are responsible for the unusual enhancement in fluorescence observed for a large number of oligonucleotides. Results are discussed in terms of a photoisomerization mechanism that deactivates the excited state and thus competes with fluorescence. The efficiency of isomerization decreases when Cy3-DNA interactions prevent rotation around the double bonds, resulting in an increase in the lifetime of the singlet excited state. We have shown that the ability of Cy3 to interact with DNA depends on the flexibility of the oligonucleotide and the presence of purines in the chain.

A fast image-stitching algorithm for characterization of cracks in large-scale structures

Linlin Wang,Billie F. Spencer Jr,Junjie Li,Pan Hu 국제구조공학회 2021 Smart Structures and Systems, An International Jou Vol.27 No.4

Visual inspection of concrete cracks has been widely used in structural health monitoring (SHM). Capturing highresolution images is an effective method to visualize a complete crack, but it is difficult to show a whole crack from a single high-resolution image. One feasible method is using image stitching technique to stitch several images into a complete crack map. However, the current image stitching method is a computationally intensive process. Numerous images are required to cover large-scale structures with sufficient resolution, this can be computationally prohibitive. To address this problem, an improved image stitching method for crack damage evaluation is proposed, which can quickly stitch the crack images without affecting the quality of the stitching or the resulting images. Rather than first stitching the images together and then determining the crack maps, we propose to first develop the crack maps for the individual images and then stitch them together. The proposed method reduces the number of redundant matching points between the original images by combining their characteristics during image stitching, so it can reduce the calculation time without affecting the quality. Also, the results will not be influenced by the image stitching seam, which can reduce the complexity of the algorithm. Several experimental results are provided in this article to demonstrate that the proposed method can reduce the calculation time without affecting the quality of image stitching and have better robustness than the current method in use.

Closed-loop structural control with real-time smart sensors

Lauren E. Linderman,Billie F. Spencer Jr. 국제구조공학회 2015 Smart Structures and Systems, An International Jou Vol.16 No.6

Wireless smart sensors, which have become popular for monitoring applications, are an attractive option for implementing structural control systems, due to their onboard sensing, processing, and communication capabilities. However, wireless smart sensors pose inherent challenges for control, including delays from communication, acquisition hardware, and processing time. Previous research in wireless control, which focused on semi-active systems, has found that sampling rate along with time delays can significantly impact control performance. However, because semi-active systems are guaranteed stable, these issues are typically neglected in the control design. This work achieves active control with smart sensors in an experimental setting. Because active systems are not inherently stable, all the elements of the control loop must be addressed, including data acquisition hardware, processing performance, and control design at slow sampling rates. The sensing hardware is shown to have a significant impact on the control design and performance. Ultimately, the smart sensor active control system achieves comparable performance to the traditional tethered system

In vitro modeling of hepatocellular carcinoma molecular subtypes for anti-cancer drug assessment

Hadassa Hirschfield,C Billie Bian,Takaaki Higashi,Shigeki Nakagawa,Tizita Z Zeleke,Venugopalan D Nair,Bryan C Fuchs,Yujin Hoshida 생화학분자생물학회 2018 Experimental and molecular medicine Vol.50 No.-

Tractable experimental model that accounts for inter-tumor molecular heterogeneity is a key element of anti-cancer drug development. Hepatocellular carcinoma is known to exhibit highly heterogeneous molecular aberrations across the tumors, including somatic genetic and epigenetic alterations. Previous studies showed that molecular tumor subtypes determined by transcriptome, as a comprehensive functional readout, are reproducibly observed across global patient populations irrespective of geographic and etiological variations. Here we demonstrate that transcriptomic hepatocellular carcinoma subtypes, S1 and S2, determined by our previous transcriptome meta-analysis of multiple clinical hepatocellular carcinoma cohorts, are presented in a panel of hepatoma cell lines widely used by the research community. Interestingly, cell line that resembles gene expression pattern of S3 subtype, representing less aggressive tumors, was not identified in the panel. MYC pathway-activated S2-like cell lines showed higher sensitivity to a small molecule BET bromodomain inhibitor, (+)-JQ1, which has anti-MYC activity. These results support the use of hepatoma cell lines as models to evaluate molecular subtype-specific drug response, which is expected to lead to development of tailored, precision care of the patients with hepatocellular carcinoma.

Semi-active damped outriggers for seismic protection of high-rise buildings

Chia-Ming Chang,Billie F. Spencer, Jr.,Zhihao Wang,Zhengqing Chen 국제구조공학회 2013 Smart Structures and Systems, An International Jou Vol.11 No.5

High-rise buildings are a common feature of urban cities around the world. These flexible structures frequently exhibit large vibration due to strong winds and earthquakes. Structural control has been employed as an effective means to mitigate excessive responses; however, structural control mechanisms that can be used in tall buildings are limited primarily to mass and liquid dampers. An attractive alternative can be found in outrigger damping systems, where the bending deformation of the building is transformed into shear deformation across dampers placed between the outrigger and the perimeter columns. The outrigger system provides additional damping that can reduce structural responses, such as the floor displacements and accelerations. This paper investigates the potential of using smart dampers, specifically magnetorheological (MR) fluid dampers, in the outrigger system. First, a high-rise building is modeled to portray the St. Francis Shangri-La Place in Philippines. The optimal performance of the outrigger damping system for mitigation of seismic responses in terms of damper size and location also is subsequently evaluated. The efficacy of the semi-active damped outrigger system is finally verified through numerical simulation.

Investigation on vibration behavior of a high-speed railway bridge based on monitoring data

Hao Wang,Qingxin Zhu,Billie F. Spencer Jr 국제구조공학회 2023 Smart Structures and Systems, An International Jou Vol.31 No.6

Field monitoring techniques offer an attractive approach for understanding bridge behavior under in-service loads. However, the investigations on bridge behavior under high-speed train load using field monitoring data are limited. The focus of this study is to explore the structural behavior of an in-service long-span steel truss arch bridge based on field monitoring data. First, the natural frequencies of the structure, as well as the train driving frequencies, are extracted. Then, the train-induced bearing displacement and structural strain are explored to identify the effects of train loads and bearings. Subsequently, a sensitivity analysis is performed for the impact factor of strain responses with respect to the train speed, train weight, and temperature to identify the fundamental issues affecting these responses. Additionally, a similar sensitivity analysis is conducted for the peak acceleration. The results indicate that the friction force in bearings provides residual deformations when two consecutive trains are in opposite directions. In addition, the impact factor and peak acceleration are primarily affected by train speed, particularly near train speeds that result in the resonance of the bridge response. The results can provide additional insight into the behavior of the long-span steel truss bridges under in-service high-speed train loads.
