Translocal imagination of Hong Kong connections: the shifting of Chow Yun-Fat's star image since 1997

Anyone who is interested in Hong Kong cinema must be familiar with one name: Chow Yun-fat (b. 1955). He rose to film stardom in the 1980s when Hong Kong cinema started to attract global attention beyond East Asia. During his early screen career, Chow established a star image as an urban citizen of modern Hong Kong through films such as A Better Tomorrow/Yingxiong bense (John Woo, 1986), City on Fire/Longhu fengyun (Ringo Lam, 1987), All About Ah-Long/A Lang de gushi (Johnnie To, 1989), God of Gamblers/Du shen (Wong Jing, 1989), and Hard Boiled/Lashou shentan (John Woo, 1992)

Inequities in Social Determinants of Health Factors and Criminal Behavior: A Case Study of Immigrant Ex-Offenders

When immigrants arrive in a new country, they often discover that being an immigrant does not allow them to integrate easily into the new society. Immigrant offenders are more likely to engage in criminal behaviors due to inequities in social determinants of health factors as a source of strain.  This study was focused on utilizing the personal experiences of immigrant offenders to discover the various circumstances that contributed to their criminal behavior. General Strain Theory has been shown to be a useable theoretical model in explaining the relationship between race/ethnicity and criminal behavior. The participants in this study were adult immigrant ex-offenders in the province of Alberta, Canada.  The results of the study indicated a consensus among ex-offenders that there are social determinants of health factors such as stress, income problem, education issues, employment issue, and health risk behaviors that have led them to commit crime.  The recommendations presented below are divided into three groups. Recommendations include:  (a) future research in federal, provincial and territorial correctional systems, (b) identification of multiple risk factors that lead an individual to commit crime, (c) crime prevention strategies that help prevent criminal behavior for immigrants.

The interactions of hadrons containing a heavy quark in the strong coupling limit of lattice QCD

Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Physics, 2005.Includes bibliographical references (p. 105-107).In this thesis we calculate the interaction potentials between two hadrons that are pinned in place on the lattice by infinitely heavy quarks. The potentials are calculated to leading order in the strong coupling and hopping parameter expansions for the following six systems: meson/meson, baryon/antimeson, baryon/baryon, meson/antimeson, baryon/meson and baryon/antibaryon. For each hadron/hadron system, we consider all allowed spin and isospin configurations for the light quarks. The interaction potentials we find take the form of one-meson-exchange potentials, whose sign and magnitude depends on the light quarks' spin and isospin.by Brian C. Fore.Ph.D

Involving Citizen Scientists in Biodiversity Observation

The involvement of non-professionals in scientific research and environmental monitoring, termed Citizen Science (CS), has now become a mainstream approach for collecting data on earth processes, ecosystems and biodiversity. This chapter examines how CS might contribute to ongoing efforts in biodiversity monitoring, enhancing observation and recording of key species and systems in a standardised manner, thereby supporting data relevant to the Essential Biodiversity Variables (EBVs), as well as reaching key constituencies who would benefit Biodiversity Observation Networks (BONs). The design of successful monitoring or observation networks that rely on citizen observers requires a careful balancing of the two primary user groups, namely data users and data contributors (i.e., citizen scientists). To this end, this chapter identifies examples of successful CS programs as well as considering practical issues such as the reliability of the data, participant recruitment and motivation, and the use of emerging technologies

Citizen science for observing and understanding the Earth

Citizen Science, or the participation of non-professional scientists in a scientific project, has a long history—in many ways, the modern scientific revolution is thanks to the effort of citizen scientists. Like science itself, citizen science is influenced by technological and societal advances, such as the rapid increase in levels of education during the latter part of the twentieth century, or the very recent growth of the bidirectional social web (Web 2.0), cloud services and smartphones. These transitions have ushered in, over the past decade, a rapid growth in the involvement of many millions of people in data collection and analysis of information as part of scientific projects. This chapter provides an overview of the field of citizen science and its contribution to the observation of the Earth, often not through remote sensing but a much closer relationship with the local environment. The chapter suggests that, together with remote Earth Observations, citizen science can play a critical role in understanding and addressing local and global challenges

Studies of Two-Phase Flow Dynamics and Heat Transfer at Reduced Gravity Conditions

The ability to predict gas-liquid flow patterns is crucial to the design and operation of two-phase flow systems in the microgravity environment. Flow pattern maps have been developed in this study which show the occurrence of flow patterns as a function of gas and liquid superficial velocities as well as tube diameter, liquid viscosity and surface tension. The results have demonstrated that the location of the bubble-slug transition is affected by the tube diameter for air-water systems and by surface tension, suggesting that turbulence-induced bubble fluctuations and coalescence mechanisms play a role in this transition. The location of the slug-annular transition on the flow pattern maps is largely unaffected by tube diameter, liquid viscosity or surface tension in the ranges tested. Void fraction-based transition criteria were developed which separate the flow patterns on the flow pattern maps with reasonable accuracy. Weber number transition criteria also show promise but further work is needed to improve these models. For annular gas-liquid flows of air-water and air- 50 percent glycerine under reduced gravity conditions, the pressure gradient agrees fairly well with a version of the Lockhart-Martinelli correlation but the measured film thickness deviates from published correlations at lower Reynolds numbers. Nusselt numbers, based on a film thickness obtained from standard normal-gravity correlations, follow the relation, Nu = A Re(sup n) Pr(exp l/3), but more experimental data in a reduced gravity environment are needed to increase the confidence in the estimated constants, A and n. In the slug flow regime, experimental pressure gradient does not correlate well with either the Lockhart-Martinelli or a homogeneous formulation, but does correlate nicely with a formulation based on a two-phase Reynolds number. Comparison with ground-based correlations implies that the heat transfer coefficients are lower at reduced gravity than at normal gravity under the same flow conditions. Nusselt numbers can be correlated in a fashion similar to Chu and Jones

Counting constituents in molecular complexes by fluorescence photon antibunching

Modern single molecule fluorescence microscopy offers new, highly quantitative ways of studying the systems biology of cells while keeping the cells healthy and alive in their natural environment. In this context, a quantum optical technique, photon antibunching, has found a small niche in the continuously growing applications of single molecule techniques to small molecular complexes. Here, we review some of the most recent applications of photon antibunching in biophotonics, and we provide a guide for how to conduct photon antibunching experiments at the single molecule level by applying techniques borrowed from time-correlated single photon counting. We provide a number of new examples for applications of photon antibunching to the study of multichromophoric molecules and small molecular complexes

Integration of Art Pedagogy in Engineering Graduate Education

The integration of STEM with the Arts, commonly referred to as STEAM, recognizes the need for human skill, creativity, and imagination in technological innovations and solutions of real-world technical problems. The STEAM paradigm changes the dominant “chalk and talk” lecture and “closed-ended” problem-solving orientation of traditional engineering pedagogy to a hands-on, studio-based, and open-ended creative learning approach, typical in art education. A growing body of literature has provided evidence of the favorable impact of situating STEAM in K-16 education. The long-term objective of this work is to promote creativity in engineering students by integrating learning methods and environments from the Arts into graduate STEM education. To this end, an integrating engineering, technology and art (ETA) educational model is developed and is currently being tested. This ETA educational model systematically merges technical instruction with studio-based pedagogy. The ETA model consists of three courses, which were piloted in the year 2017. In each course, engineering and art instructors and students collaborated for 15 weeks on design projects. These projects ranged from drones to architectural installations
