The palace of Pak Tai: a study of the historyand architecture of Pak Tai Temple in Wan Chai
No full text“The historic environment is part of everyday life. It is accessible to everyone. It is around us every time we travel to work, drive to the supermarket or go to school. Studying it, being able to read and interpret it, enriches people’s lives as much as literature, music, or history. Access creates interest, interest stimulates understanding, understanding brings enjoyment, enjoyment leads to commitment. All contribute to the quality of life.”

What Alison said above is really the author’s passion to study the Architectural Conservation Programme (ACP) and the aspiration for writing this dissertation. The Pak Tai Temple in Wan Chai is a heritage place in urban area where it is accessible to every one. However, many people live in Wan Chai do not know the Temple. As a novice of architectural conservation, the author attempts to explore the tangibles as well as intangibles on a fundamental basis to collect all available data and information for this research. As far as possible, the author collects the primary information from the temple keeper, the local residents, worshippers and other stakeholders. At the same time, the author searches archival documents from public library websites as well as historic records from the Hong Kong Public Records Office.
The author hopes that this dissertation would not be an inventory record of the Pak Tai Temple on architecture. He wants it to be a collection of real life stories about the activities occurred in the Temple and its neighbouring community. It is the stories about the people and the changing social life here composite the heritage of the Temple. Of course, the essential tangible items for heritage conservation have been recorded in details.
The author regrets that he is not a graduate of architecture, so this dissertation will not provide too much technical information.published_or_final_versionConservationMasterMaster of Science in Conservatio
Real-Time, in-situ Detection of Pathogenic Bacteria on Food Surfaces Using a Surface-Scanning Coil Detector and Phage-Based Magnetoelastic Biosensors
No full textThis research uses wireless magnetoelastic (ME) biosensors combined with a surface-scanning coil detector for the direct, real-time detection of Salmonella Typhimurium on fresh food surfaces. The ME biosensor consists of an ME resonator as the sensor platform and E2 phage as the bio-recognition element. For in-situ detection of surface bacterial contaminants, a surface-scanning coil detector was designed and its performance was evaluated. The designed coil was used to excite the ME biosensor and then measure the biosensor’s signal in response to the potential presence of bacteria. A model of the sensor’s longitudinal vibration and an equivalent electrical circuit of the detection system were constructed to theoretically evaluate the coil design and its effect on signal amplitude and detection distance. In order to explain the reason for the different signal amplitudes, a theory of mutual inductive coupling between a vibrating sensor and the coil detector was proposed. Two types of coil detectors were evaluated for design and comparison: solenoid and planar spiral coils. Based on the sensor’s longitudinal vibration and the structure of the coils, the planar spiral coil detector was found to be more sensitive and to give a much larger signal amplitude at resonance. Furthermore, the ability to simultaneously measure multiple sensors on surfaces with the planar spiral coil has been demonstrated.
A gradual change of the resonant frequency was observed over time during the reaction between an E2 phage-coated ME biosensor and S. Typhimurium on fresh food surfaces. The effects of a humid environment were researched and the limit of detection was statistically determined. This new technique eliminates the time-consuming and costly sample selection and preparation steps previously required
Cosmic-ray all-electron spectrum with MAGIC
No full textStudying high-energy cosmic-ray electrons and positrons is crucial in understanding nearby cosmic-ray sources. These particles experience significant energy loss during their propaga- tion through the Interstellar Medium (ISM) via synchrotron radiation and inverse-Compton scattering, leading to a short and energy dependent path-length in our Galaxy. Electrons and positrons with energies in the TeV ranges are expected to originate from sources within a distance of approximately one kiloparsec. In addition to the astrophysical origin, the possibility of a Dark Matter scenario makes the study of these particles even more intriguing.
Numerous experiments, including balloon-borne and satellite missions, as well as ground- based Imaging Atmospheric Cherenkov Telescopes (IACTs), have extensively studied the energy spectrum of cosmic-ray electrons and positrons. Although IACTs are designed to detect γ-rays, electrons and positrons can also be detected due to the similar air shower development process. Due to their large collection areas, IACTs can provide large statistics electrons and positrons at TeV energies. However, extracting the electron and positron events against the dominating hadronic background remains a significant challenge for IACTs. Additionally, the ability to reconstruct the spectrum of cosmic-ray electrons and positrons demonstrates the capabilities of IACTs to study diffuse sources.
In this thesis, two methods are introduced for estimating the background cosmic-ray hadron events in order to further extract the electron and positron events based on Random Forest (RF) algorithm: the RF-Fit method, which is a template fit method, and the Two- Step RF method, which is a hard cut method based on two steps of RF training. The RF-Fit method is a commonly used technique for analyzing the cosmic-ray electron and positron spectrum with IACTs, which has been validated by instruments like H.E.S.S. and VERITAS. To adapt this method for use with MAGIC, I designed a Monte-Carlo (MC) tracking simulation method to ensure that the simulated background template precisely matches the Field of View (FoV) of the observation data. The Two-Step RF method is a novel approach that uses RF to accurately train between signal events and signal-like background events. By applying a tight cut of a few percent for the electron survival rate, the background events can be reduced to approximately 20%. After thorough evaluations of the systematics, both methods yield consistent reconstructed cosmic-ray electron and positron spectra in the energy range between 300 GeV and 6 TeV. The spectra can be described by a broken power-law and confirm the presence of an energy break around 900 GeV from MAGIC data for the first time, which is consistent with previous measurements.
Afterwards, the contribution to the cosmic-ray electron and positron spectrum from Supernova Remnant (SNR) and pulsar models are compared with MAGIC data. The model preferred by MAGIC suggests that a Monogem pulsar is a source of the broken power law spec- trum, where the pulsar appears above the background but experiences suppression at high energies
Chai Jing: The Power of Vulnerability
No full textIn the past seventeen years Chai Jing has risen from China’s official media to become a recognized investigative journalist, public intellectual, author, and more recently, an independent filmmaker and environmental activist. Her experience and work reflect how China’s news apparatus has reformed to adapt to the drastic societal changes with emotion being used to open up new ways of news communication. Her documentary Under the Dome further shows how the internet has transformed the ecology of media and provided innovative platforms for social engagement. Chai’s embracing her own feelings of vulnerability, which dominated the beginning of her career, and using it to channel public feelings and drive news reporting has made her a distinctively controversial media personality. Her leaving the CCTV can be viewed as a self-marginalization that helps her sustain that vulnerability, through which she gains resilience and critical power. The use of maternal voice in Under the Dome exemplifies her use of the power of vulnerability in its most mature form. The controversiality about that voice signals that post-socialist China remains a space where environmental and gender discourses are contested and negotiated

Overview of van chai in Thue Thien Hue, Vietnam: Tradition, present and future challenges
No full textDuring process of seeking methods of advanced fishery management experience to apply into small-scale fishery in Thua Thien Hue – Viet Nam, the author is surprised that some advanced countries also apply similar methods that the traditional fishing village associations (Van Chai) has been managed fishery activities in lagoons in Thua Thien Hue since feudal times. The changes by returning back to original points in order to connect and glue the traditional quintessences of fisheries management, to advanced management in foreign countries is a core in an argued approach as well as in reality of managing small - scale fishery in Thua Thien Hue- Viet Nam presently.
Based on that, this report has introduced previous fishery management in Tam Giang lagoon based on traditional fishery villages, to research ways to reform the management of small scale fisheries based upon local fisher’s associations; outlined a scenarios for fishery management patters for future based on local community in Thua Thien Hue. The system expect to solve disputes in term of fishermen, fishing grounds and fishery resources.
The report is a synthesized collection from researches of the author and relevant documents available. The findings show that fishery villages in Thua Thien Hue used to be successfully managed fishery resources through its own mechanism (regulations) and actively support of feudal authorities (a form of primary co-management) and practical experience derived from efforts to manage modern fishery. In Thua Thien Hue at present, the selectively inheritance of traditional values of fishery villages is one of potential ways in managing fishery in Tam Giang lagoon specifically.KEYWORDS: Van Chai, Fishery management, Thue Thien Hue, Vietnam, Small-scale fishery, Fisheries economics, Fishery resource
Improving intercultural communication skills: A challenge facing institutions of higher education in the 21st century
No full textFollowing discussion of the rationales for improving students' intercultural communication skills, this article described how the professors at the University of Rhode Island and their counterparts around the world use the Internet as a mechanism for improving a student's intercultural awareness and sensitivity. Using the Internet, students here and abroad debate on timely, relevant topics to become aware of how people of different cultures see things differently. In addition, they write and exchange cross-cultural dialogues and explanatory notes to become interculturally sensitive. In this way, the students meet with their future partners of the global workplace, while honing their computer skills, writing skills, and enhancing their intercultural awareness and sensitivity. However, those in higher education who want to implement this kind of Internet-based teaching technique on a permanent basis must first address several difficult issues, including how to find like-minded professors here and abroad who are willing to participate. If correctly used over time, these techniques (international e-mail debate and cross-cultural dialogues) can improve students' intercultural awareness and sensitivity. Assessment of whether or not this improvement lasts over a period of time presents a quantitative problem. Defining intercultural sensitivity practically and satisfactorily is the first task facing educators interested in following this path toward improved communication. One of the greatest challenges facing the institutions of higher education of the 21st Century is how to improve intercultural communication skills of their students. Accompanied by a yet-to-be-developed instrument for quantitative measurement of long-term outcomes, projects like the international e-mail debate and cross-cultural dialogue may well become the tools for understanding and negotiation in the new global environment. --

Label-free Immunosensor for Toxin Detection in Food Matrix
No full textA method for the detection of biological toxins in foods has to be sensitive, rapid, and field-applicable since toxin detection is on the front line of food safety and food protection against bioterrorism. In this thesis a sensitive, rapid, and label-free electrochemical impedance spectroscopy (EIS) immunosensor was developed and its performance in real foods was demonstrated. To improve the sensitive of EIS immunosensor, nanoporous aluminum was applied as the substrate of EIS immunosensor. Well ordered nanoporous aluminum having ~30nm in pore diameter was obtained by anodizing food grade aluminum in 0.3M oxalic acid at 40V. EIS immunosensor for the detection of staphylococcal enterotoxin B (SEB) or ricin was developed by immobilizing anti-SEB or ricin on nanoporous aluminum using 3-aminopropyltriethoxysilane (APTES). Particularly efficient immobilization of antibody (Ab) was attained by silanization of aluminum in 2 % APTES for 4hrs. A time-resolved EIS of immunosensor was performed to investigate the effect of immunoreaction on impedimetric signal outputs. Immunoreaction between immobilized i
