The hidden curriculum : an exploration into the potential for green buildings to silently communicate a pro-environmental message
Creators: name: Mitchell, Amanda
Publisher: name: University of British Columbia
Year: 2010

description: This qualitative research study explores whether high caliber green buildings can passively communicate a pro-environmental message to their occupants, and if so, whether some design strategies are more effective than others at communicating this message. The sample consisted of 26 participants (students, staff and faculty) who were occupants of one of the four study buildings: the C.K. Choi Institute for Asian Research and the Liu Institute for Global Issues at the University of British Columbia in Vancouver, BC; Princess Street Campus at Red River College in Winnipeg, MB; and the Computer Science Building at York University in Toronto, ON. Semidirected interviews of 20 to 80 minutes in duration (the average interview was 43 minutes) were conducted in situ by the researcher. This research found that to varying degrees green buildings can passively communicate a pro-environmental message to their occupants. How many "green" design features an occupant could identify appears to form the core message, which is enhanced or diminished by the operational context, occupant experience and comparisons to other buildings. Certain design features were more often associated with a pro-environmental message and are therefore more effective at communicating this message. These emphatically green design solutions, such as salvaged materials and photovoltaics, either utilized strategies that are heavily connected with pro-environmental behaviour (the 3R's, energy conservation and water conservation) or are icons of the environmental movement. These design solutions acted as "triggers" by capturing an occupant's attention and causing them to link the strategy with a proenvironmental construct. Complicating the communication process is that a conclusive definition for "pro-environment" did not exist among occupants. This means that a pro-environmental message may not be communicated unless the building embodies the occupant's specific definition for the term. This research provides direction to designers and building managers on how to increase the potential that a green building will communicate a pro-environmental message to their occupants, and it suggests that green buildings can be heuristic learning tools if they are designed with an aesthetic that challenges existing constructs.

description: We study the deconfining phase transition in SU(N) gauge theories at nonzero temperature using a matrix model of Polyakov loops. The most general effective action, including all terms up to two spatial derivatives, is presented. At large N, the action is dominated by the loop potential: following Aharony et al., we show how the Gross--Witten model represents an ultra-critical point in this potential. Although masses vanish at the Gross--Witten point, the transition is of first order, as the fundamental loop jumps only halfway to its perturbative value. Comparing numerical analysis of the N=3 matrix model to lattice simulations, for three colors the deconfining transition appears to be near the Gross--Witten point. To see if this persists for N >= 4, we suggest measuring within a window ~1/N^2 of the transition temperature.

description: The Food-Energy-Water (FEW) nexus for urban sustainability needs to be analyzed via an integrative rather than a sectoral or silo approach, reflecting the ongoing transition from separate infrastructure systems to an integrated social-ecological-infrastructure system. As technology hubs can provide food, energy, water resources via decentralized and/or centralized facilities, there is an acute need to optimize FEW infrastructures by considering cost-benefit-risk tradeoffs with respect to multiple sustainability indicators. This paper identifies, categorizes, and analyzes global trends with respect to contemporary FEW technology metrics that highlights the possible optimal integration of a broad spectrum of technology hubs for possible cost-benefit-risk tradeoffs. The challenges related to multiscale and multiagent modeling processes for the simulation of urban FEW systems were discussed with respect to the aspects of scaling-up, optimization process, and risk assessment. Our review reveals that this field is growing at a rapid pace and the previous selection of analytical methodologies, nexus criteria, and sustainability indicators largely depended on individual FEW nexus conditions disparately, and full-scale cost-benefit-risk tradeoffs were very rare. Therefore, the potential full-scale technology integration in three ongoing cases of urban FEW systems in Miami (the United States), Marseille (France), and Amsterdam (the Netherlands) were demonstrated in due purpose finally.

description: Hybrid alkaline cement (HAC) is composed of a significant proportion of supplementary cementitious materials (SCMs) such as fly ash (FA) and/or granulated blast furnace slag (GBFS), a minor proportion of ordinary Portland cement (OPC), and alkali activators. A series of HACs were prepared with 10-30% OPC and 90- 70%SCM using 0-8% alkali activator and curing at room temperature. The samples were then characterized using compressive strength, setting time, X-Ray Powder Diffraction (XRD), Scanning Electron Microscopy (SEM), 1H Low-field NMR technology, isothermal conduction calorimetry, and thermogravimetric analysis (TG). The effects of type and dosage of activator used, and the ratio of raw materials on the mechanical, setting and durability properties of different HACs were studied. The results indicated that the setting times of HACs decreases with increasing alkali activator dosage. The HACs with high proportion of SCMs, cured at ambient temperature and activated by appropriate dosage of alkali activator perform similar or higher compressive strength than OPC. The compressive strength of HACs increases with the increasing of Na2O dosage. By selecting the type of alkali activators and adjusting their dosage, controlling the proportion of OPC in HAC system, HAC can be prepared at ambient temperature, which is useful for engineering application. The durability properties of HAC concrete are indeed crucial for its application in the construction industry. The results indicate that HAC concrete demonstrates significantly greater resistance to harsh environmental conditions compared to OPC concrete, exhibiting robust performance in both early and later stages of development. HAC concrete exhibits clear advantages over OPC in terms of resistance to chloride corrosion, sulfate penetration and alkali–silica reaction (ASR)-induced expansions.

description: Given a finite family $\mathcal U$ of finite subsets of $\mathbb Z^d\setminus \{0\}$, the $\mathcal U$-$voter\ dynamics$ in the space of configurations $\{+,-\}^{\mathbb Z^d}$ is defined as follows: every $v\in\mathbb Z^d$ has an independent exponential random clock, and when the clock at $v$ rings, the vertex $v$ chooses $X\in\mathcal U$ uniformly at random. If the set $v+X$ is entirely in state $+$ (resp. $-$), then the state of $v$ updates to $+$ (resp. $-$), otherwise nothing happens. The $critical\ probability$ $p_c^{\text{vot}}(\mathbb Z^d,\mathcal U)$ for this model is the infimum over $p$ such that this system almost surely fixates at $+$ when the initial states for the vertices are chosen independently to be $+$ with probability $p$ and to be $-$ with probability $1-p$. We prove that $p_c^{\text{vot}}(\mathbb Z^d,\mathcal U)<1$ for a wide class of families $\mathcal U$. We moreover consider the $\mathcal U$-Ising dynamics and show that this model also exhibits the same phase transition.

description: We explore the temperature dependence of the heavy-quarkonium interaction based on the Bhanot-Peskin leading order perturbative QCD analysis. The Wilson coefficients are computed solving the Schrodinger equation in a screened Coulomb heavy-quark potential. The inverse Mellin transform of the Wilson coefficients then allows for the computation of the 1S and 2S heavy-quarkonium gluon and pion total cross section at finite screening/temperature. As a phenomenological illustration, the temperature dependence of the 1S charmonium thermal width is determined and compared to recent lattice QCD results.

Effect of formal CH/P exchange on tandem Cope rearrangement and [2 + 2] cycloaddition of cis-1,2-diethylnylcyclopropane and its mono-hetero analogues

description: Effect of formal one and two CH/P exchange(s) on tandem Cope rearrangement and [2 + 2] cycloaddition of cis-1,2-diethylnylcyclopropane and its mono-hetero analogues has been investigated theoretically in the gas phase at the DFT (B3LYP/6-31+G(d)) level. The activation free energy for the first step, i.e., Cope rearrangement decreases successively on replacing one and two CH moieties of cis-1,2-diethylnylcyclopropane and its mono-hetero analogues with P atom(s), which could be rationalized on the basis of weaker C = P π bond than C = C π bond. However, this trend is not maintained in the second step, i.e. [2 + 2] cycloaddition of the initially formed intermediate; instead, the activation free energy for monophospha- and diphospha- analogues is slightly higher, which may be attributed to the lesser stability of monophospha- and diphosphacyclobutene rings than cyclobutene. The CASSCF calculations indicate that except the intermediates generated from the Cope rearrangement of cis-diethynylthiirane and cis-bis(phosphaethynyl)cyclopropane which are expected to follow concerted mechanism for the [2 + 2] cycloaddition, in all other cases, apparently, there is no preference for the concerted or stepwise mechanism. Inclusion of the dispersion correction in the DFT functional does not cause significant changes in energetics.

description: This paper presents a new variational data assimilation (VDA) approach for the formal treatment of bias in both model outputs and observations. This approach relies on the Wasserstein metric stemming from the theory of optimal mass transport to penalize the distance between the probability histograms of the analysis state and an a priori reference dataset, which is likely to be more uncertain but less biased than both model and observations. Unlike previous bias-aware VDA approaches, the new Wasserstein metric VDA (WM-VDA) dynamically treats systematic biases of unknown magnitude and sign in both model and observations through assimilation of the reference data in the probability domain and can fully recover the probability histogram of the analysis state. The performance of WM-VDA is compared with the classic three-dimensional VDA (3D-Var) scheme on first-order linear dynamics and the chaotic Lorenz attractor. Under positive systematic biases in both model and observations, we consistently demonstrate a significant reduction in the forecast bias and unbiased root mean squared error.

Publisher: name: University of British Columbia
Year: 2010

description: Background: The prevalence of cardiovascular disease in individuals with spinal cord injury (SCI) is as high as or greater than in the general population, yet assessment of cardiovascular fitness rarely occurs in individuals with SCI. Purpose: 1) To review current literature and develop guidelines to assist clinicians in choosing appropriate submaximal tests for the evaluation of cardiovascular fitness in individuals with SCI; 2) to design a submaximal single-stage arm ergometer test (SSSAET) for use in individuals with SCI; and 3) to determine the test-retest reliability and criterion validity of this exercise test. Methods: A systematic review of the literature was done to identify and evaluate arm exercise tests that submaximally measure cardiovascular fitness in individuals with SCI. To evaluate the SSSAET, 30 subjects with SCI were assessed using the American Spinal Injury Association (ASIA) scale, isometric strength testing, a physical activity questionnaire, the SSSAET, and a VO₂peak test. Test-retest reliability of the SSSAET was determined by having subjects complete the SSSAET on two days, separated by one week. Criterion validity was determined by comparing the results from the SSSAET with the VO₂peak test. Results: The literature review identified six submaximal arm exercise tests for measuring cardiovascular fitness in individuals with SCI, but all tests featured limitations that prevented widespread clinical use. Test-retest reliability of the SSSAET was excellent (ICC=0.81-0.90). As well, correlations between VO₂peak and outcomes of the SSSAET ranged from r=0.63- 0.92, indicating good to excellent criterion validity. Conclusions: Clinical recommendations were provided for the existing arm exercise test protocols. Testing showed that the SSSAET has acceptable test-retest reliability and criterion validity, however further research is necessary before the SSSAET will be ready for implementation as a clinical tool to assess baseline and changes in cardiovascular fitness in individuals with SCI.

description: Ebben a tanulmányban a fenntartható fejlődés aktuális hazai és nemzetközi helyzetének kutatása kapcsán, szekunder kutatási módszerek segítségével a svéd–magyar gazdaság összehasonlító elemzését mutatom be. A két ország helyzetének vizsgálatát a Svédországban használt különböző innovatív és egyben környezettudatos megoldások bemutatásával kezdem. Köztudott, hogy Svédország a környezettudatos szemlélet és a társadalmi jóléti modell élenjáró európai képviselője, ezért néhány projekten keresztül érdemes megvizsgálnunk ennek a kivételes szerepnek a hátterét. A tanulmány első részében tehát betekintést nyerhetünk a Göteborgban található GRYAAB szennyvízkezelő társaság és a stockholmi Hammarby Sjöstad városrész központjának, a Glasshus Ett intézménynek mindennapi tevékenyégébe. Ezen kívül, az alnarpi egyetem és egy salix (energiafűz) farm bemutatásával különböző energianövények termesztésének módszertani és gazdasági aspektusaival ismerkedhetünk meg. A tanulmány második felében néhány fontosabb gazdasági mutatószámot vizsgálok, hogy segítségükkel feltárhassam a két ország között fennálló különbségek okait. Ezután a hazai fenntarthatóság jelenlegi helyzetét tárom fel és igyekszem megismerni a központi, kormányzati célkitűzéseket, valamint a civil és közösségi kezdeményezéseket. ------------------------------------------------------- In this study I write the comparative analysis of both the Swedish and the Hungarian economy – with the help of subsidiary investigations – and with regard to the research connected to the current Hungarian and national state of sustainable development. I start the study of the two countries with the description of the different innovative and environmentally friendly solutions used in Sweden. Sweden is well-known as the main European representative of environmentalism and the social welfare system model, therefore it is worth to examine the background of this special state through some projects. So, in the first part of this study we can get an insight into structure Gryaab a wastewater-treatment company which can be found in Göteborg and the daily activities of Glasshus Ett which is the centre of Hammarby Sjöstad in Stockholm. Besides these with the showing of the University of Alnarp and a salix farm we can get acquainted with the economical and methodological aspects of different energy-plants culture. In the other part of this study I investigate some significant economical indexes in order to discover the causes of the differences of the two countries. Then I discover the current state of domestic sustainability and try to get to know more about central, governmental purposes as well as the civil and communal initiatives.

description: Differential privacy (DP) is a promising framework for privacy-preserving data science, but recent studies have exposed challenges in bringing this theoretical framework for privacy into practice. These tensions are particularly salient in the context of open-source software libraries for DP data analysis, which are emerging tools to help data stewards and analysts build privacy-preserving data pipelines for their applications. While there has been significant investment into such libraries, we need further inquiry into the role of these libraries in promoting understanding of and trust in DP, and in turn, the ways in which design of these open-source libraries can shed light on the challenges of creating trustworthy data infrastructures in practice. In this study, we use qualitative methods and mental models approaches to analyze the differences between conceptual models used to design open-source DP libraries and mental models of DP held by users. Through a two-stage study design involving formative interviews with 5 developers of open-source DP libraries and user studies with 17 data analysts, we find that DP libraries often struggle to bridge the gaps between developer and user mental models. In particular, we highlight the tension DP libraries face in maintaining rigorous DP implementations and facilitating user interaction. We conclude by offering practical recommendations for further development of DP libraries.

We show that this behavior is hole-density-dependent and does not originate from surface anisotropy. The presence of uniaxial anisotropy as well its dependence on the hole-concentration and temperature can be explained in terms of the p-d Zener model of the ferromagnetism assuming a small trigonal distortion.

description: Competitiveness and competition are basic categories of the market economy. While analyzing the foreign trade they acquire an international aspect. After the Polish accession to the EU, the Polish dairy industry showed a very favourable performance as regards the foreign trade, which can confirm its competitive position. It was confirmed with a statistical analysis but in order to retain such position further restructuring processes will have to be carried out. The restructuring processes would lead to an improvement in efficiency. The reform of dairy market regime tending to an abolishment of milk quotas can lead to further improvement in foreign trade results. Therefore comparative advantages would be maintained. / Synopsis. Konkurencja i konkurencyjność to podstawowe kategorie ekonomii rynku, a w analizach handlu zagranicznego mają one aspekt międzynarodowy. Polskie mleczarstwo po integracji z UE osiągnęło bardzo korzystne wyniki w handlu zagranicznym, które sugerują dobrą pozycję konkurencyjną. Analiza statystyczna potwierdziła to, ale utrzymanie tych przewag będzie wymagało kontynuacji procesów restrukturyzacyjnych, których efektem będzie poprawa efektywności. Reforma regulacji rynku, zmierzająca do likwidacji kwot mlecznych, może przyczynić się do wzrostu przetwórstwa i poprawy wyników handlowych. W rezultacie możliwe będzie utrzymanie przewag komparatywnych.

description: We propose a versatile robotic system for kitting and assembly tasks which uses no jigs or commercial tool changers. Instead of specialized end effectors, it uses its two-finger grippers to grasp and hold tools to perform subtasks such as screwing and suctioning. A third gripper is used as a precision picking and centering tool, and uses in-built passive compliance to compensate for small position errors and uncertainty. A novel grasp point detection for bin picking is described for the kitting task, using a single depth map. Using the proposed system we competed in the Assembly Challenge of the Industrial Robotics Category of the World Robot Challenge at the World Robot Summit 2018, obtaining 4th place and the SICE award for lean design and versatile tool use. We show the effectiveness of our approach through experiments performed during the competition.
title: The effects of forest disturbance and fragmentation on fruit-feeding butterflies in Trinidad
Creators: name: Wood, Byron Charles
Publisher: name: The Open University
Year: 1999

description: This thesis explores the use of tropical butterflies as indicators of forest disturbance, fragmentation and forest recovery. The disturbance level of habitats was found to be characterised by the rate of the fraction of species accumulated, with species in undisturbed habitats accumulating more slowly. Undisturbed habitats, but not more disturbed ones, were found to have a vertically stratified butterfly assemblage between the forest understorey and canopy, and certain species were found to be horizontally stratified from the forest edge.

No significant effect of breaks in a forest habitat to the dispersal of certain fruit-feeding butterflies was found, but for species which did not cross breaks, it was not possible to determine whether this was due to low numbers of captures or because breaks acted as barriers to dispersal.

Cissia arnaea (Nymphalidae: Satyrinae) was present in significantly greatest abundance in 30 year selectively logged forest, even though canopy openness was not significantly different from that found in 5 year forest. Conversely, Colobura dirce (Nymphalidae: Nymphalinae) was found in greatest abundance in the O and 5 year forest and least abundant in the 30 year forest. It is possible that these species could be used to indicate forest recovery following selective logging.

Population size estimates and average residency rates were calculated for Cissia penelope and Morpho peleides from fruit trap data. Community structure in the Cissia genus was explored, and the relationship between local abundance and geographic range size investigated and certain restricted range species were not found to be adversely affected by forest disturbance in Trinidad as expected (Thomas 1991 and Hamer et al. 1997).

description: The article proves the Collatz conjecture by showing that the original conjecture corresponds to an equivalent similar conjecture on a reduced set of elements, and computes an analytical solution both to the top-down and the bottom-up versions. The article defines also a new set of axioms, named Peano-Collatz axioms, that is a slight generalization of the Peano axioms. The Peano-Collatz axioms are a theoretical framework for the study of the Collatz function and of similar structures.

We find that the $trans$ preference by the characteristic crystal field in the VO$_4$H$_2$ octahedron in addition to a coherent shrinkage along the V-H-V direction, taking place when such direction is consistent among neighboring hydrogens, stabilize the anion ordering observed in experiment. Our study gives an important clue for controlling the anion ordering in transition metal oxyhydrides.

description: The non equilibrium relaxational dynamics of the solid on solid model on a disordered substrate and the Sine Gordon model with random phase shifts is studied numerically. Close to the super-roughening temperature $T_g$ our results for the autocorrelations, spatial correlations and response function as well as for the fluctuation dissipation ratio (FDR) agree well with the prediction of a recent one loop RG calculation, whereas deep in the glassy low temperature phase substantial deviations occur. The change in the low temperature behavior of these quantities compared with the RG predictions is shown to be contained in a change of the functional temperature dependence of the dynamical exponent $z(T)$, which relates the age $t$ of the system with a length scale ${\cal L}(t)$: $z(T)$ changes from a linear $T$-dependence close to $T_g$ to a 1/T-behavior far away from $T_g$. By identifying spatial domains as connected patches of the exactly computable ground states of the system we demonstrate that the growing length scale ${\cal L}(t)$ is the characteristic size of thermally fluctuating clusters around ``typical'' long-lived configurations.

description: The article proves the Collatz conjecture by showing that the original conjecture corresponds to an equivalent similar conjecture on a reduced set of elements, and computes an analytical solution both to the top-down and the bottom-up versions. The article defines also a new set of axioms, named Peano-Collatz axioms, that is a slight generalization of the Peano axioms. The Peano-Collatz axioms are a theoretical framework for the study of the Collatz function and of similar structures.

This version makes some changes of wording in the abstract (previously there was too much use of the word "conjecture"), and corrects a couple of typo (a double "m >" in a definition insead of a single one, and an "s" instead of a "z" in the note to Appendix 3.)
title: Magmatic And Tectonic Evolution Of Southern Tibet And The Himalaya
Creators: name: Williams, Helen Myfanwy
Publisher: name: The Open University
Year: 2000

description: The Himalaya-Tibetan orogen has become the paradigm for continental collision and is central to deciphering continental tectonics. Neogene extension in the orogen is not predicted by plate tectonic theory, and its significance is widely debated.

In the Himalaya, north-south extension is restricted to the Southern Tibetan Detachment System (STDS), which juxtaposes the High Himalayan Crystalline Series (HHCS) against the Tibetan Sedimentary Series (TSS). 40Ar-39Ar ages from HHCS and TSS of the Garhwal Himalaya indicate that STDS movement initiated between 17.3 ± 0.4 to 24.3 ± 1.6 Ma (2σ), synchronous with Main Central Thrust (MCT) movement. One-dimensional thermal modelling suggests that the STDS is a reactivated thrust, implying a fundamental change in Himalayan tectonics in the early Miocene.

The onset of east-west extension in southern Tibet is constrained by north-south trending shoshonitic dykes to be 13.3 ± 0.8-18.3 ± 2.7 Ma. Trace-element modelling indicates that the shoshonitic dykes and associated lavas in southern and northern Tibet were derived by ≤2% melting of enriched sub-continental lithospheric mantle (SCLM) at 65-85km. The northern and southern shoshonites have distinctive isotopic (εNd(i), north, -5.5 to-10.3; south -8.8 to - 18.1) and major element signatures that relate to distinct SCLM sources corresponding to the tectonically accreted terranes of the plateau. The trace-element compositions of these sources, determined by inverse modelling, suggest subduction-related metasomatism. 40Ar- 39Ar dating of xenocrystic phlogopites indicates metasomatism of the southern SCLM occurred at 62±2 Ma, synchronous with collision.

These data link Neogene extension to a thermally perturbed lithosphere. SCLM thinning following slab detachment explains magmatism, extension and uplift in southern Tibet. Episodic convective removal of the SCLM is proposed for northern Tibet. In view of these models, initiation of extension at 18.3±1.6 Ma in southern Tibet places a minimum constraint on plateau uplift. This overlaps with STDS and MCT movement, implying that changes in Himalayan tectonics are controlled by plateau uplift.

description: The transmission spectrum for one atom strongly coupled to the field of a high-finesse optical resonator is observed to exhibit a clearly resolved vacuum-Rabi splitting characteristic of the normal modes in the eigenvalue spectrum of the atom-cavity system. A new Raman scheme for cooling atomic motion along the cavity axis enables a complete spectrum to be recorded for an individual atom trapped within the cavity mode, in contrast to all previous measurements in cavity QED that have required averaging over many atoms.

description: While recent experiments confirm the existence of hundreds of topological electronic materials, only a few exhibit the coexistence of superconductivity and a topological electronic state. These compounds attract significant attention in forefront research because of the potential for the existence of topological superconductivity, paving the way for future technological advancements. $SrSn_{4}$ is known for exhibiting unusual superconductivity below the transition temperature ($T_{C}$) of 4.8 K. Recent theory predicts a topological electronic state in this compound, which is yet to be confirmed by experiments. Systematic and detailed studies of the magnetotransport properties of $SrSn_{4}$ and its Fermi surface characterizations are also absent. For the first time, a quantum oscillation study reveals a nontrivial $π$ Berry phase, very light effective mass, and high quantum mobility of charge carriers in $SrSn_{4}$. Magnetotransport experiment unveils large linear transverse magnetoresistance (TMR) of more than 1200% at 5 K and 14 T. Angle-dependent transport experiments detect anisotropic and four-fold symmetric TMR, with the maximum value ($\sim$ 2000%) occurring when the angle between the magnetic field and the crystallographic b-axis is 45 degree. Our results suggest that $SrSn_{4}$ is the first topological material with superconductivity above the boiling point of helium that displays such high magnetoresistance.

Fermi-ball dark matter from a first-order phase transition

description: We propose a novel dark matter (DM) scenario based on a first-order phase transition in the early universe. If dark fermions acquire a huge mass gap between true and false vacua, they can barely penetrate into the new phase. Instead, they get trapped in the old phase and accumulate to form macroscopic objects, dubbed Fermi-balls. We show that Fermi-balls can explain the DM abundance in a wide range of models and parameter space, depending most crucially on the dark-fermion asymmetry and the phase transition energy scale (possible up to the Planck scale). They are stable by the balance between fermion's quantum pressure against free energy release, hence turn out to be macroscopic in mass and size. However, this scenario generally produces no detectable signals (which may explain the null results of DM searches), except for detectable gravitational waves (GWs) for electroweak scale phase transitions; although the detection of such stochastic GWs does not necessarily imply a Fermi-ball DM scenario.

Cai Tingkai - the national hero from Lingnan
Creators: name: Lau, Wing-Hong
Publisher: name: University of British Columbia
Year: 2010

description: On 28th January 1932, Cai Tingkai ([Chinese Characters]) (1892-1968), and Jiang Guangnai ([Chinese Characters]) (1888-1967) led the Chinese 19th Route Army to fight the Japanese in Shanghai for 33 days and became instant household names among the Chinese. The battle was known as the 1.28 Incident. Lloyd Eastman in 1974 pointed out that historians from then onwards would have difficulties in deciding who is the greater among the two. In the thesis I shall argue that Cai Tingkai is a military hero comparable to Yue Fei ([Chinese Characters]) (1103-1142). My thesis will explicate why, on the heel of patriotism and regionalism Cai became a national hero in the 1930s. In China, military hero often belongs to a period of unrest and warfare, whose single-minded sincerity and faith in his cause will not allow him to escape and compromise in face of a challenge. His courage, sense of destiny and duty guide him forward, but he is tied to the losing side that will eventually doom him. In 1932 Cai took the cause so common among heroes: in practical term the struggle has been futile, and in many instances, even counter-productive. Cai lived in a period when the old social order had disintegrated. It was a good opportunity for regionalism to manifest itself: the North was China's traditional political center of authority and orthodoxy, but in the 1930s the South generated a current to challenge it. Unknown to Cai, he was a participant as well as a creator of that historical current. Cai discarded his Guomindang (GMD) ([Chinese Characters]) identity in November 1933, but he never was a Communist. Because he was a non-conformist in the GMD, his historical position as a national hero has been undeservedly played down by the Nanjing regime. Also, because of his former GMD identity, for political reasons, he is unlikely to be remembered as a national hero in Mainland China. The purpose of this thesis is to put Cai back to the right place in the annuals of history.
