Identifying Effective Management Factors Across Human Errors – A Case in Elevator Installation
Pin-Chao Liao,Zhangming Ma,Heap-Yih Chong 대한토목학회 2018 KSCE JOURNAL OF CIVIL ENGINEERING Vol.22 No.9
Human errors are recognized as the main factor in causing construction accidents. Previous studies mainly focused on justifying theories associated with human errors and hardly quantifying the causal relations between external stimuli and human errors. Hence, the aim of this research is to develop comprehensive management measurements for addressing human errors in construction projects. Deductive reasoning was used to describe the methodological process. Firstly, we constructed a theoretical model of human errors based on Cognitive Reliability and Error Analysis Method (CREAM) and knowledge-combined structure learning algorithm. Then, Bootstrap method was adopted to verify the reliability of network topology, while the similarity-flooding algorithm was used to analyze similarity of factors across various causal models for their commonalities. Subsequently, Bayesian parameter estimation was to analyze the sensitivity of the nodes. The results show that inadequate quality control, design failure and inattention are the most fundamental causes of human errors in promoting safety management. This research has proposed an analytical approach that consolidated the influential mechanics to reflect the overall influence of a root cause in the human error. Ultimately, the research lays an analytical foundation for safety management research in the future.

Microfluidics has been developed as an important platform for biochemical/chemical reactions. How to enhance the performance of a microfluidic chemical reactor is one of the core concerns when designing the microfluidic device. In the pressure-driven microfluidics without micromixer, parabolic flow profile dominates the behaviors of the laminar flow as well as the reaction particles such as DNA fragments, proteins, and enzymes. The aim of this study is to elucidate and answer a question: does a groove-shape passive micromixer improve the performance of a continuous flow type microfluidic reactor? Two mold inserts were micro-milled in the experiments, one had regular microchannels and the other one had regular microchannels with groove-shape passive micromixers, and both polymeric chips were manufactured with hot embossing techniques. Multiple experiments were realized on both chips to evaluate the groove-shape passive mixer to the performance of a continuous flow type microfluidic reactor. Polymerase chain reaction (PCR) is a typical example of chemical reaction in microfluidics, a 99 bp DNA fragment from λ-DNA was used as the target in the experiments. In this study,multiple experiments were carried out, analyzed, and concluded that the groove-shape passive mixing is not beneficial to the performance of a continuous flow type microfluidic reactor. The results showed that a regular microfluidic device without mixing had better amplification efficiency of the target DNA fragments, which indicated that using a real-time passive mixing component inside a continuous flow environment, increasing the chance of protein absorption and strengthening shear force to molecules, might cause the negative impact to the PCR reaction performance.

Since human behavior has been argued as one of the most critical leading indicators of accidents, effective intervention in workers’ behavior may foster improved safety performance. Given that human behavior is directed by cognition, researchers have proposed various cognitive models of human behavior in order to provide a clearer understanding of how to allocate management resources. However, the influence of human cognition on behavior remains an overarching concept, rather than providing an understanding of the heterogeneity among various trades. Therefore, cognition research provides no guidance regarding how to strategically allocate management resources such as training. This study employed structural equation modeling to identify the cognitive structures of two trades (reinforcing steel bar and elevator workers). We find that the cognitive structures of workers in these sample trades are significantly different, indicating that management strategies should vary accordingly. Training of mechanical workers should focus on crew leads, who can further influence self-efficacy, risk comparisons, and workers’ perception of external conditions. For rebar crews, safety training should focus on self-supporting defense capability and elucidating dangerous behaviors. External conditions have a significant role in ensuring worker safety; safe facilities engender safe behaviors. This study lays a foundation of strategic resource allocation for behavioral management on construction jobsites.

The larch-fruit-like acetylferrocene micro-nanomaterials and beltlike acetylferrocene micro-nanomaterials have been cross-correspondingly prepared in bidirection by the top-down and bottom-up approach, respectively, and characterized by scanning electron microscope, transmission electron microscope and X-ray diffractometer. UV-Vis absorption spectra show that the redshift was found in the acetylferrocene micro-nanomaterials compared to that in solution. The formation mechanism of the acetylferrocene micro-nanomaterials is also proposed. This work provides a new strategy for the material synthesis and preparation and may realize the reuse of organometallic materials.
Transnational Negotiations: Transracial Adoption and Narratives of Return in Lisa Ko’s The Leavers
Pin-chia Feng 한국영어영문학회 2023 영어 영문학 Vol.69 No.4
The first Chinese arrived in New York in 1847 and founded Manhattan’s Chinatown. New York later saw a significant influx of Chinese in the late 1870s when anti-Chinese violence was mounting in the American West; thus began the extended history of the Chinese American community in the Big Apple. While there are differences and similarities among the different generations of Chinese immigrants, new immigrant writing is marked by a special interest in metropolitan New York. This Atlantic turn away from the predominantly transpacific narrative of Chinese America may have been influenced by the fact that in the 1970s New York City replaced San Francisco as the largest gathering place of Chinese Americans in North America. This ethnogeographical shift is faithfully reflected in the immigrant writing of the new millennium, such as Lisa Ko’s The Leavers (2017). In The Leavers, Ko reveals her strong racial and social consciousness by writing about the precarious lives of undocumented Chinese workers and the affective cost of transracial adoption in her debut novel. Peilan, the immigrant mother from Fuzhou, goes into debt to be smuggled into New York only to find herself entrapped in another sweatshop. Her American-born son Deming is adopted by a white family when she is imprisoned in a camp for undocumented immigrants. This paper analyzes the struggles of transnational negotiations in The Leavers, emphasizing particularly on the son’s perspective regarding issues of transracial adoption and narratives of return, to explore the complex and changing ethnic historiography of Chinese America.
We was girls together: The Double Female Bildungsroman in Toni Morrison`s Love
( Pin Chia Feng ) 한국영미문학페미니즘학회 2007 영미문학페미니즘 Vol.15 No.2
In this paper, I read Love as a double female Bildungsroman and argue that, as in Morrison`s second novel Sula, Love is primarily a story about interrupted love between girls. This reading focuses on the narratives of (anti-)Bildung of the two female characters, Christine Cosey and Heed the Night Johnson Cosey, in relation to the emotional conflicts that are associated with love. As readers, we are invited to work with the author to ferry out the why and how of this interruption and to witness the power of love when the two characters are reunited.

Ever since 1992, when Taipei Women’s Rescue Foundation (TWRF) was commissioned by Taiwan’s Ministry of Foreign Affairs to identify the former victims of sexual slavery from the island, the staff and volunteers of the foundation have been instrumental in caring and providing wellness workshops for this group of elderly women who suffered tremendous physical and psychological traumas. To document the life narratives and celebrate the spirit of perseverance of former Taiwanese “comfort women,” or amas in the Taiwanese dialect, TWRF also produced two documentary films, A secret buried for fifty years: Taiwanese comfort women [Yang, C. Y. (Director). (1998). A secret buried for fifty years: Taiwanese comfort women [A Ma De Mi Mi]. Taipei: Taipei Women's Rescue Foundation.] and Song of the reed [Wu, H. C. (Director). (2015). Song of the reed [Lu Wei Zhi Ge]. Taipei: Taipei Women’s Rescue Foundation]. This paper examines the various efforts of TWRF to empower and care for the grandmothers and analyze Song of the reed, in which the final five group workshops and activities of 2011 and 2012 are recorded.
