Cities in the age of global migration : integration of mainland Chinese in Vancouver, Canada
Creators: name: Feng, Lisi
Publisher: name: University of British Columbia
Year: 2015

description: Since the late 1990s, the People’s Republic of China has emerged as the largest source of foreign students, tourists, skilled and low-skilled workers for the Pacific cities and regions. Upon arrival, the ‘new’ Chinese migrants have to carve out a place for themselves, which entails more than looking for jobs and shelter. In particular, they find themselves in a social milieu shaped by both new and long-established Chinese groups in the receiving places. Using migration flows between Mainland China and Vancouver as a case study, I explore specific processes and mechanisms that directly shape the diversity of migrant integration experiences and the variegated relations between migrant integration and the socioeconomic and spatial transformation of the Vancouver region. Specifically, I seek to understand how certain political economic characteristics of place (in terms of economic structures, political cultures, processes and institutions) have hindered and facilitated the livelihood production of migrant groups in multifaceted ways. Two methodological approaches inform my study: comparative historical analysis and agency-structure linkage. I argue that specific historical trajectory of urban development in localities in China and Vancouver offer very different structures of opportunities that enable individual migrant families to build different human capacity, hence, their capacity to adapt to a new life when they move from place to place. Group differences challenge the taken-for-granted claims of ‘Chineseness’ and the stale concept of ‘Chinese community’ in public debates and policy-making. By placing the multiplicity of Mainland Chinese experiences at the centre of my research, I have opened up new lines of theorizing about the substantive meaning of integration as opposed to providing definitive answers to when and how to achieve integration. The impossibility of presenting a coherent, unified trajectory through which one settles down with a definitive sense of belonging attests to the complexity and precariousness of migrant integration.
Supported and unsupported palladium nanoparticles for heterogeneous catalysis
Creators: name: Man, Renee Wai Ying

description: The development of new methods to prepare Pd-containing nanomaterials for catalysis are reported. Monodisperse, catalytically active Pd0 nanoparticles were prepared using a one-pot procedure, and new insights into the mechanism of the formation of these catalytically active Pd0 nanoparticles were obtained. A number of key intermediates and byproducts were determined using NMR and IR spectroscopies. Furthermore, addition of Lewis bases such as TOPO and DMSO to the reaction mixture greatly reduced the temperature at which highly monodisperse nanoparticles were formed. This effect was shown to be applicable to other Pd precursors in preparing Pd0 nanoparticles. Spherical Pd0@m-SiO2 core-shell nanoparticles were prepared and characterized by a number of techniques, including TEM, PXRD, TGA, and XPS. These nanoparticles consist of a Pd0 core enclosed by a mesoporous silica shell and are prepared using a simple, scalable one-pot procedure. The reaction conditions were crucial in controlling the morphology and pore diameter of the nanoparticles synthesized. Acid treatment of the Pd0@m-SiO2 nanoparticles was found to be the most suitable method in removing CTAB. The morphology, surface area, and pore diameter of the core-shell nanoparticles remained intact after removal of CTAB. A new ceria-containing core-shell material, PdO@m-CeO2, was prepared via templating from Pd0@m-SiO2 and PdO@m-SiO2 nanoparticles. The absence of Pd0 and presence of Pd2+ was explained by the possible formation of a solid solution composed of Ce1-xPdxO2-δ when Pd0 was the core. The catalytic activity of the nanoparticles was examined by performing the catalytic oxidation of methane. As well, the silica channels of the Pd0@m-SiO2 nanoparticles were used as selector to separate molecules based on their size. Size-selective hydrogenation was investigated using the porous silica shell of the Pd0@m-SiO2 nanoparticles as a selector, where the porous shell controlled the selectivity by the size of the substrates. Hydrogenation of a small molecule, 1-hexene, in CDCl3 using acid-treated Pd0@m-SiO2 nanoparticles occurred quickly, while the hydrogenation of a larger substrate, O-allyl cholesterol proceeded more slowly. However, similar results were observed using commercially available Pd/C as the catalyst. Narrowing the pore diameter of Pd0@m-SiO2 nanoparticles showed drastic difference in reaction rates between 1-hexene and O-allyl cholesterol.

description: A wide swing charge sensitive amplifier (CSA) has been developed, as a part of a front-end electronics (FEE) readout ASIC, for a prototype silicon tungsten (Si-W) based electromagnetic (EM) calorimeter. The CSA, designed in 0.35 $μ$m N-well CMOS technology using 5V MOS transistors, has a wide linear operating range of 2.6 pC w.r.t the input charge with a power dissipation of 2.3 mW. A noise figure (ENC) of 820 e$^-$ at 0 pF of detector capacitance with a noise slope of 25 e$^-$/pF has been achieved (when followed by a CR-RC$^2$ filter of 1.2 $μ$s peaking time). This design of CSA provides a dynamic range (ratio of maximum detectable signal to noise floor) of 79 dB for the maximum input charge of 2.6 pC when connected to a silicon detector with a capacitance of 40 pF. Using folded cascode architecture-based input stage and low voltage high swing current mirrors as the load, the CSA provides an enlarged output swing when biasing the output node towards one supply rail and utilizing the voltage range towards the opposite rail. The design philosophy works for both polarities of a large input signal. This paper presents the design of CSA with a wide negative output swing for an anticipated input signal of positive polarity in the target application with a known detector biasing scheme.

description: The use of the hyperspherical harmonic (HH) basis in the description of bound states in an $A$-body system composed by identical particles is normally preceded by a symmetrization procedure in which the statistic of the system is taken into account. This preliminary step is not strictly necessary; the direct use of the HH basis is possible, even if the basis has not a well defined behavior under particle permutations. In fact, after the diagonalization of the Hamiltonian matrix, the eigenvectors reflect the symmetries present in it. They have well defined symmetry under particle permutation and the identification of the physical states is possible, as it will be shown in specific cases. The problem related to the large degeneration of the basis is circumvented by constructing the Hamiltonian matrix as a sum of products of sparse matrices. This particular representation of the Hamiltonian is well suited for a numerical iterative diagonalization, where only the action of the matrix on a vector is needed. As an example we compute bound states for systems with $A=3-6$ particles interacting through a short-range central interaction. We also consider the case in which the potential is restricted to act in relative s-waves with and without the inclusion of the Coulomb potential. This very simple model predicts results in qualitative good agreement with the experimental data and it represents a first step in a project dedicated to the use of the HH basis to describe bound and low energy scattering states in light nuclei.

description: Auf der internationalen Agenda steht Tuberkulose weit oben und war im Herbst 2018 erstmals Thema in der Generalversammlung der Vereinten Nationen. Dort wurde eine historische politische Deklaration verabschiedet mit dem Ziel, den weltweiten Kampf für die Elimination einer der ältesten Krankheiten der Menschheit zu beschleunigen. Eine niedrige TB-Inzidenz sowie ein gut funktionierendes Sozial- und Gesundheitssystem versetzen Deutschland in diesem globalen Unterfangen zwar in eine gute Ausgangslage. Die Zahl der Tuberkulose-Erkrankungen in Deutschland war 2018 jedoch ähnlich hoch wie 2017, berichtet das RKI im Epidemiologischen Bulletin 11/12 2019. Ein jährlicher Rückgang um 10 Prozent wäre aber erforderlich, um das Ziel der WHO zu erreichen, Tuberkulose bis 2050 zu eliminieren. Daher sind in der Tuberkulosekontrolle auch in Deutschland zusätzliche Anstrengungen notwendig. Von zentraler Bedeutung sind leistungsfähige Gesundheitsämter, um im Umfeld eines Tuberkulosepatienten infizierte oder bereits erkrankte Personen zu identifizieren und eine Verbreitung der Tuberkulose zu verhindern. Bei Symptomen wie länger bestehendem Husten, Nachtschweiß, Fieber und Gewichtsabnahme sollte immer auch an Tuberkulose gedacht werden. Bedeutsam sind auch eine frühzeitige Resistenztestung und eine resistenzgerechte Behandlung. Auch die molekulare Surveillance ist ein wichtiger Beitrag zur Elimination der Tuberkulose und sollte landesweit etabliert werden.

description: This paper presents a thorough survey of recent work addressing energy efficient multicast routing protocols and secure multicast routing protocols in Mobile Ad hoc Networks (MANETs). There are so many issues and solutions which witness the need of energy management and security in ad hoc wireless networks. The objective of a multicast routing protocol for MANETs is to support the propagation of data from a sender to all the receivers of a multicast group while trying to use the available bandwidth efficiently in the presence of frequent topology changes. Multicasting can improve the efficiency of the wireless link when sending multiple copies of messages by exploiting the inherent broadcast property of wireless transmission. Secure multicast routing plays a significant role in MANETs. However, offering energy efficient and secure multicast routing is a difficult and challenging task. In recent years, various multicast routing protocols have been proposed for MANETs. These protocols have distinguishing features and use different mechanisms

A dissociable role for dopamine receptors in the basolateral amygdala in risk/reward decision making
Creators: name: Larkin, Joshua Daniel
Publisher: name: University of British Columbia
Year: 2015

description: Different aspects of cost/benefit decision making involving uncertain rewards are facilitated by distributed corticolimbic circuits linking different regions of the prefrontal cortex, ventral striatum and the basolateral amygdala (BLA). Dopamine (DA) also plays an integral role in promoting choice of larger, uncertain rewards, as manipulations of DA transmission the PFC or nucleus accumbens alters risky choice. However, considerably less is known about how DA activity within the BLA regulates risk-based decision making. The present study assessed the effects of DA receptor modulation within the BLA on risk-based decision making, utilizing a probabilistic discounting task. Rats were trained to choose between a small/certain lever (1 sugar pellet) and a large/risky lever (4 sugar pellets) delivered in a probabilistic manner. The odds of obtaining the larger reward decreased in a systematic manner across 4 blocks of trials (100%, 50%, 25%, & 12.5%) during a daily session. Animals received counterbalanced intra-BLA microinfusions of the D1 receptor antagonist SCH23390, D2 antagonist eticlopride, the D1 agonist SKF81297 or D2 agonist quinpirole. Blockade of D1 receptors in the BLA caused rats to discount the larger/uncertain reward significantly more when compared to their performance after saline infusions, resulting in a reduction in risky choice most prominently during blocks where delivery of the larger reward was uncertain. Further, stimulation of the D1 receptor produced an optimization effect on choice behavior, increasing risky choice when it is more advantageous and decreasing risky choice when it is not advantageous. D1 receptors in the BLA seem to have an important role in facilitating optimal decision making and promoting choice of larger uncertain rewards. D2 receptor blockade showed a significant reduction in reward sensitivity, while stimulation of the D2 receptor did not affect choice behavior. More generally, these findings highlight a key contribution by mesoamygdala DA in regulating certain aspects of cost/benefit decision making, particularly the D1 receptor which may be the primary mechanism through which DA exerts its effect the BLA. These findings may have important implications to understanding mechanisms underlying disruptions in decision making and reward processes in psychiatric disorders linked to dysfunction of the DA system and the amygdala.

description: GRB 041219A is one of the longest and brightest gamma-ray bursts (GRBs) ever observed. It was discovered by the INTEGRAL satellite, and thanks to a precursor happening about 300 s before the bulk of the burst, ground based telescopes were able to catch the rarely-observed prompt emission in the optical and in the near infrared bands. Here we present the detailed analysis of its prompt gamma-ray emission, as observed with IBIS on board INTEGRAL, and of the available X-ray afterglow data collected by XRT on board Swift. We then present the late-time multi-band near infrared imaging data, collected at the TNG, and the CFHT, that allowed us to identify the host galaxy of the GRB as an under-luminous, irregular galaxy of about 5x10^9 M_Sun at best fit redshift of z=0.31 -0.26 +0.54. We model the broad-band prompt optical to gamma-ray emission of GRB 041219A within the internal shock model. We were able to reproduce the spectra and light curve invoking the synchrotron emission of relativistic electrons accelerated by a series of propagating shock waves inside a relativistic outflow. On the other hand, it is less easy to simultaneously reproduce the temporal and spectral properties of the infrared data.

Genre and parody in the music of the Beatles
Creators: name: Connolly, Michael
Publisher: name: University of British Columbia
Year: 2015

description: From the earliest outbreak of “Beatlemania” in 1963 to the announcement of their breakup in 1970, The Beatles fulfilled, exceeded, and reformed our conceptions of popular music. They have enjoyed an enduring popularity with critics and audiences and have cemented their position as one of the most celebrated acts in popular culture. Although it would be difficult to attribute their success to a single factor, it could be argued that their eclectic sound ensured their mass appeal. As their careers progressed, The Beatles effortlessly combined and moved between different genres. Many of these genres were atypical for popular music of the 1960s and can be regarded as parody. This thesis approaches parody as an important stylistic trait of The Beatles’ music. Parody is a broad concept that can be found in a number of forms of art and entertainment. By drawing from literary criticism and musicological discourse, this study develops a broader understanding of parody in which popular musicians evoke the music of another genre through borrowing and create a critical distance between their work and the preexisting one. Further investigation reveals how The Beatles applied parody to their music and how it was used by the band to connect with their listeners. In such songs as “Back In The U.S.S.R.” and “Happiness Is A Warm Gun,” The Beatles parody different musical genres in order to evoke social commentary. Genre parody is not exclusive to individual songs. It is one of the unifying threads in Sgt. Pepper’s Lonely Hearts Club Band, in which The Beatles parody the English music hall and use genre to connect themes on the album. Despite these instances, parody remains an underexplored practice in their music. Many scholars of the band will acknowledge the musical and critical elements associated with parody; however, they do not use the term, nor identify parody as a recurring practice in The Beatles’ music. This thesis hopes to shed light on this topic and add to our understanding of the rich legacy of The Beatles.

description: Herschel's PACS instrument observed the environment of the binary system Mira Ceti in the 70 and 160 micron bands. These images reveal bright structures shaped as five broken arcs and fainter filaments in the ejected material of Mira's primary star. The overall shape of the IR emission around Mira deviates significantly from the expected alignment with Mira's exceptionally high space velocity. The observed broken arcs are neither connected to each other nor are they of a circular shape; they stretch over angular ranges of 80 to 100 degrees. By comparing Herschel and GALEX data, we found evidence for the disruption of the IR arcs by the fast outflow visible in both Halpha and the far UV. Radial intensity profiles are derived, which place the arcs at distances of 6-85" (550 - 8000 AU) from the binary. Mira's IR environment appears to be shaped by the complex interaction of Mira's wind with its companion, the bipolar jet, and the ISM.

Mutagenesis studies of charged residues in the hERG K+ channel
Creators: name: Wu, Yue
Publisher: name: University of British Columbia
Year: 2015

description: The loss-of-function mutations in the human ether-à-go-go–related gene (hERG) K+ channel serve as one of the primary genetic substrates for congenital long QT syndrome (LQTS), and unlike most Kv channels with fast-activating kinetics, hERG channels have unusually slow activation kinetics. Thus, it is a necessary task to understand mechanisms of hERG gating, especially since the charge-rich S4 segments play such an important role in channel opening in response to membrane potential changes. Despite the structural homology to other Kv channels, how individual S4 charges in hERG are positioned and moved under the influence of membrane voltage changes remains controversial. Therefore, this thesis focuses on the molecular basis of individual charge residues underlying S4 movement. To monitor S4 movement associated with the voltage- and time-dependence accessibility by the sulfhydryl-specific agent MTSET, we mutated a series of S4 charges (K525-K538) to uncharged glutamine (Q) in a mutant in which cysteine replaced the isoleucine at position 521 near the top of S4. We found that K525, R528, and R534 mainly secure the S4 position in the resting state. Our results on the rate of S4 movement suggest that R528, R531, and R537 potentially facilitate the transition of S4 from the closed to the active state. Conversely, neutralization of the bottom lysine K538 significantly accelerates the rate of S4 movement, implying an important constraint on S4 by K538. To further investigate this unique role of K538, we measure the gating charge contributions of K538 and D411 (a potential ion-pairing in S1) with the cut-open vaseline gap technique. Our data show that mutations of both charges to neutral residues (K538Q and D411N) accelerate the time dependence of charge movement while both mutant channels are gated with faster kinetics than control over a physiologically relevant range of depolarizations. This highlights the substantial contribution of both residues to slow hERG gating.

The role of adsorbed enzymes in determining the hydrolysis kinetics of pretreated lignocellulosic biomass
Creators: name: Mok, Yiu Ki
Publisher: name: University of British Columbia
Year: 2015

description: The cost-effective production of sugars from biomass continues to remain challenging, partly due to the relatively high enzyme/protein loading required to effectively hydrolyze pretreated lignocellulosic substrates. Previous works have shown conflicting observations regarding the correlation between enzyme adsorption and the hydrolytic performance of an enzyme mixture. Unfortunately, it has proven difficult to accurately determine the roles of adsorbed enzymes during the hydrolysis of lignocellulosic substrates, in part because of the interference that protein determination methods encounter from the release of sugars and other biomass derived materials, the lack of a hydrolysis strategy for hydrolysis with only adsorbed enzymes and the use of “model” substrates in many studies. To better understand the role that adsorbed enzymes play in cellulose deconstruction, it is important that we are able to accurately quantify protein distribution and enzyme performance. Various protein quantification assays were initially assessed for their ability to accurately and reproducibly quantify protein/enzymes during typical biomass hydrolysis conditions. However, the ninhydrin assay, which was the most promising assay due to its specificity for protein and compatibility with most compounds derived from lignocellulosic samples, still suffered from the incompatibility with sugar degradation products, long hydrolysis times and potentially wide-ranging standard deviations. To overcome these limitations, an accurate and rapid modified ninhydrin assay was developed which employed a sodium borohydride treatment to eliminate sugar interference followed by acid hydrolysis at 130ºC, reducing the overall reaction time to 4 hours. Utilizing the modified ninhydrin assay, the role of adsorbed enzymes in determining the rate and extent of hydrolysis of several different pretreated biomass substrates was then assessed. Once the distribution of enzymes reached equilibrium, after 60 minutes, those enzymes that were adsorbed or free in solution were separated by centrifugation and subsequently assessed for their ability to hydrolyze various cellulosic substrates at different enzyme loadings. It was apparent that the adsorbed enzymes were critically important as the removal of those enzymes in solution resulted in no significant decrease in the rate and extent of hydrolysis. By using the adsorbed enzymes, enzyme loadings could be reduced by up to 53% while resulting in similar hydrolysis yields.

description: Die Entwicklung von Medikamentenresistenz ist global derzeit eines der größten Hindernisse im Kampf gegen TB. Die Problematik resistenter TB ist auch in Deutschland präsent. Zwar sind die Resistenzraten in den letzten Jahren relativ stabil geblieben, die RKI-Surveillancedaten der letzten 10 Jahre zeigen jedoch, dass bei einem Großteil der Fälle multiresistenter TB (MDR-TB) mehr als nur die beiden wichtigsten TB-Medikamente Isoniazid und Rifampicin unwirksam sind. Um eine Ausbreitung von MDR-TB zu verhindern, sind rechtzeitige und sachgemäße Resistenztestungen sowie eine resistenzgerechte, individualisierte Behandlung durch Experten/-innen unabdingbar. Hierbei sind aktuelle Entwicklungen zur Diagnostik, Behandlungsmöglichkeiten und Medikamenten zu berücksichtigen. In Epidemiologischen Bulletin 11/12 2019 beschreiben Maurer et al. die von der WHO empfohlene Umstellung auf ein orales Behandlungsregime und betonen auch hier, dass die Möglichkeiten der Resistenztestung ausgeschöpft werden sollten.

description: In this paper, global optimization (GO) Lipschitz problems are considered where the multi-dimensional multiextremal objective function is determined over a hyperinterval. An efficient one-dimensional GO method using local tuning on the behavior of the objective function is generalized to the multi-dimensional case by the diagonal approach using two partition strategies. Global convergence conditions are established for the obtained diagonal geometric methods. Results of a wide numerical comparison show a strong acceleration reached by the new methods working with estimates of the local Lipschitz constants over different subregions of the search domain in comparison with the traditional approach.

description: Recently, Kazakov, Gromov and Vieira applied the discrete Hirota dynamics to study the finite size spectra of integrable two dimensional quantum field theories. The method has been tested from large values of the size L down to moderate values using the SU(2) x SU(2) principal chiral model as a theoretical laboratory. We continue the numerical analysis of the proposed non-linear integral equations showing that the deep ultraviolet region L -> 0 is numerically accessible. To this aim, we introduce a relaxed iterative algorithm for the numerical computation of the low-lying part of the spectrum in the U(1) sector. We discuss in details the systematic errors involved in the computation. When a comparison is possible, full agreement is found with previous TBA computations.

description: The asymptotic giant branch (AGB) stars X Her and TX Psc have been imaged at 70 and 160 microns with the PACS instrument onboard the Herschel satellite, as part of the large MESS (Mass loss of Evolved StarS) Guaranteed Time Key Program. The images reveal an axisymmetric extended structure with its axis oriented along the space motion of the stars. This extended structure is very likely to be shaped by the interaction of the wind ejected by the AGB star with the surrounding interstellar medium (ISM). As predicted by numerical simulations, the detailed structure of the wind-ISM interface depends upon the relative velocity between star+wind and the ISM, which is large for these two stars (108 and 55 km/s for X Her and TX Psc, respectively). In both cases, there is a compact blob upstream whose origin is not fully elucidated, but that could be the signature of some instability in the wind-ISM shock. Deconvolved images of X Her and TX Psc reveal several discrete structures along the outermost filaments, which could be Kelvin-Helmholtz vortices. Finally, TX Psc is surrounded by an almost circular ring (the signature of the termination shock?) that contrasts with the outer, more structured filaments. A similar inner circular structure seems to be present in X Her as well, albeit less clearly.

Being in between : discovering the identities of emerging adult immigrants
Creators: name: Cohen, Julie-Anne
Publisher: name: University of British Columbia
Year: 2015

description: The proposed research aimed to discover the ways in which emerging adult immigrants negotiate their cultural identities within the context of both cultural and developmental transition. Using a grounded theory research design, 10 intensive-interviews were conducted with emerging adult immigrants, ages 19-27, who had immigrated and saw Canada as their long-term home. Emerging data was analyzed and results of this study yielded a conceptual model of cultural identity formation (MCIF) for emerging adult immigrants. The MCIF suggests that One’s Motivation and Sense of Agency to Create a New Identity is at the core of participant’s navigation of cultural identities. Additionally, the MCIF for emerging adult immigrants outlined six higher-order categories (1) Family Cultural Rigidity, (2) Connections Specific to Canada, (3) Connection to a Same Cultured Community, (4) Sense of Permanency, (5) Desire to Preserve Culture of Origin, (6) Desire to fit in to Canadian Culture, as well as two overarching factors (a) Dimension of Time and the (b) Dimension of Age that were found to be influential on participant’s overall sense of cultural identities (Blended, Dual, Disconnected, Intermediate). The present model and accompanying theory contributes to a deeper understanding of the lived experiences and sense of cultural selves of emerging adult immigrants during these phases of change. Recommendations for further research are made, as well as recommendations for counsellors working with an emerging adult immigrant population.

description: In sensor networks communication by broadcast methods involves many hazards, especially collision. Several MAC layer protocols have been proposed to resolve the problem of collision namely ARBP, where the best achieved success rate is 90%. We hereby propose a MAC protocol which achieves a greater success rate (Success rate is defined as the percentage of delivered packets at the source reaching the destination successfully) by reducing the number of collisions, but by trading off the average propagation delay of transmission. Our proposed protocols are also shown to be more energy efficient in terms of energy dissipation per message delivery, compared to the currently existing protocol.

description: Bei der Modellierung, Steuerung und Regelung nichtlinearer Prozesse werden häufig zwei- bzw. mehrdimensionale Kennfelder eingesetzt. Sie können äußerst effektiv in lokal verallgemeinernden Speichern abgelegt werden. Der Beitrag stellt an Hand von drei Beispielen und ihren Weiterentwicklungen dar, dass sehr verschiedenartige Ansätze möglich sind und die Auswahl gemäß ihren inherenten Vor- und Nachteilen von der ins Auge gefassten Anwendung bestimmt werden sollte. Teil II behandelt als dritten Ansatz eine Methode, die von einer mathematischen Darstellung beliebig geformter Flächen im Raum inspiriert wurde und fasst die Aussagen der beiden Teile des Aufsatzes zusammen.

Modelling the decay patterns and harvested wood product pools of residential houses
Creators: name: Xie, Sheng H.
Publisher: name: University of British Columbia
Year: 2015

description: The harvested wood products (HWP) in use carbon pool plays a beneficial but frequently unrecognized role in climate change mitigation by storing carbon that has been removed from the atmosphere and providing services that can substitute for emission intensive products. Countries with a culture of building houses with wood use a majority of HWP for structural purposes and, due to the long-lived nature of houses, the structural HWP within these dwellings can last for a long time. Long-lived products have the potential to make a major contribution to the HWP in use pool and accurate quantification of this pool is an important topic worthy of detailed investigation. This study reviewed published HWP decay models and developed a “regression-aggregation-fit” methodology to accurately model the inverse sigmoidal decay patterns of houses at the national level. Using this method, the end-use half-lives of U.S. single-family and multi-family houses, U.S. mobile homes, Canadian residential houses and Norwegian residential houses were estimated to be 137 years, 44 years, 92 years and 146 years, respectively. For comparison, the default product half-lives recommended by the IPCC are 35 years for sawnwood and 25 years for wood-based panels. The direct application of these default product half-lives to quantify the HWP pool in houses is likely to result in substantial underestimation of this carbon pool. The Gamma distribution model was shown to be the most applicable generalized model for describing the country-specific decay pattern of houses. It adequately modelled housing data sets from three different countries and it was the best of the six models evaluated. This model was used to quantify the structural HWP pool in U.S. single-family and multi-family houses and in 2009 this pool was 668 Tg C, which was about 20% larger than published estimates. A constant mass input scenario indicated that this pool may act as a sink for about 750 years with a saturation value of about 1.2 Pg C. This methods developed in this thesis should improve the accuracy of national greenhouse gas inventory reporting for countries with extensive forests and a tradition of building with wood.
