description: Quantum walks have by now been realized in a large variety of different physical settings. In some of these, particularly with trapped ions, the walk is implemented in phase space, where the corresponding position states are not orthogonal. We develop a general description of such a quantum walk and show how to map it into a standard one with orthogonal states, thereby making available all the tools developed for the latter. This enables a variety of experiments, which can be implemented with smaller step sizes and more steps. Tuning the non-orthogonality allows for an easy preparation of extended states such as momentum eigenstates, which travel at a well-defined speed with low dispersion. We introduce a method to adjust their velocity by momentum shifts, which allows to investigate intriguing effects such as the analog of Bloch oscillations.

Characterization of somatostatin receptor in rat/mice brain : implication in Huntington's disease
Creators: name: Rajput, Padmesh Singh
Publisher: name: University of British Columbia
Year: 2013

description: Somatostatin (SST) is a multifunctional peptide present in most brain regions as well as in peripheral organs. In QUIN/NMDA-induced excitotoxicity, an experimental model of Huntington’s disease (HD), SST positive interneuron coexpressing NPY/NADPH-d/bNOS are selectively spared whereas, projection neurons expressing NMDA receptors and DARPP- 32 are vulnerable. SST plays neuroprotective role in excitotoxicity, however, which SSTR subtypes mediate the neuroprotective role is not known. Accordingly, as a first step, we describe the colocaliztion of SSTR subtypes with DARPP-32 to determine the percentage of receptor subtypes in projection neurons. We further extended our study and compared HD transgenic mice (R6/2) with SSTR1 and 5 double knock out mice. In both strains we compared the expression pattern of NMDARs, DARPP-32, SST, bNOS and SSTRs and key downstream signaling pathways linked to the neuronal loss in HD such as PI3K, ERK1/2 PKC-α, synapsin-IIa, enkephalin and calpain. Our data shows that SSTR1/5 double knock out mice mimic the neurochemical changes of HD transgenic mice indicating a key neuroprotective role of SSTR1 and 5 in HD. To derive direct physiological implications and mechanistic explanations for the role of SSTR subtypes in excitotoxicity we used striatal brain slices and determined the effect of SSTR1 and 5 agonist, alone or in combination with NMDA on key proteins such as DARPP-32, calpain, PSD-95 and signaling pathways associated with NMDA induced neurotoxicity. Our results here show significant decrease in NMDA currents and dissociation of NMDARs heterodimerization upon treatment with SSTR1 and 5-specific agonist. Our data further demonstrates significant decrease in NMDARs expression and upregulation of SSTR1 and 5 upon agonist treatment. Unlike NMDA, activation of SSTR1 or 5 in striatal slices induced DARPP-32 phosphorylation at Thr34 and Thr75 enhanced CREB phosphorylation and inhibits expression of calpain and PSD-95. The data presented in this thesis provides a new insight for the role of SSTR subtypes in excitotoxicity with relevance to neurological disorders.

description: The cosmological consequences of $f(R)$ gravity are reviewed in the framework of recent data obtained by PAMELA (Payload for Antimatter Matter Exploration and Light-nuclei Astrophysics) experiment. This collaboration has reported an excess of positron events that cannot be explained by conventional cosmology and particle physics, and are usually ascribed to the dark matter presence (in particular, weak interacting massive particles). The dark matter interpretation of PAMELA data has motivated the study of alternative cosmological models (with respect to the standard cosmology) owing to the fact that they predict an enhancement of the Hubble expansion rate, giving rise, in such a way, to thermal relics with a larger relic abundance. Our analysis shows that $f(R)$ cosmology allows to explain the PAMELA puzzle for dark matter relic particles with masses of the order or lesser than $10^2$ GeV in the regime $ρ^c \lesssim ρ^m $ where $ρ^c$ is the curvature density and $ρ^m$ the radiation density. For the model $f(R)=R+αR^n$, it then follows that $n\simeq 1$ and small corrections with respect to General Relativity could lead indeed to address the experimental results. However other interesting cosmological models can be considered during the pre-BBN epoch as soon as the BBN constraints are relaxed. In such a case, the PAMELA data can be fitted for a larger class of $f(R)$-models.

Gaining New Understanding of Sarcomere Length Nonuniformities in Skeletal Muscles

description: Sarcomere lengths are non-uniform on all structural levels of mammalian skeletal muscle. These non-uniformities have been associated with a variety of mechanical properties, including residual force enhancement and depression, creep, increased force capacity, and extension of the plateau of the force-length relationship. However, the nature of sarcomere length non-uniformities has not been explored systematically. The purpose of this study was to determine the properties of sarcomere length non-uniformities in active and passive muscle. Single myofibrils of rabbit psoas (n=20; with 412 individual sarcomeres) were subjected to three activation/deactivation cycles at short, intermediate, and long sarcomere lengths of 2.7, 3.2, and 3.6 µm respectively, and individual sarcomere lengths were measured at 4 passive and 3 active points during the activation/deactivation cycles. The primary results were that sarcomere length non-uniformities did not occur randomly but were governed by some structural and/or contractile properties of the sarcomeres and that sarcomere length non-uniformities differed greatly between the active and passive state. We propose that the mechanisms that govern the systematic sarcomere lengths non-uniformities observed in active and passive muscle are associated with the variable number of contractile proteins and the variable number and stiffness of titin filaments in individual sarcomeres.

description: This project is an effort to create a live performance system borrowing features from different disciplines in sonic arts and employing multiple audio techniques. The project involves an immersive interactive sonic arts system that combines aspects of sound installation, interactive lighting design, and live sonic arts performance. The completed system was demonstrated with a live performance including three performers from different disciplines in music. The main idea of this project is to create a system that brings together elements from different concepts in sonic arts such as spatial audio, generative music, interactive audio system, and electroacoustic music. The system can be described as a living organism which interacts with the audience while being controlled by both humans and machines in real time. I designed a sonic environment which is alive and running from the very first moment that the audience enters the venue until they leave; a hybrid human-machine controlled system that can project sound through the performance space. In addition to sound art and digital audio, this project examines the relationship between sound and lights in music performances and how the use of lighting in live music can enhance the audience’s experience.

description: The experimental investigation of the $I_c(B)$--$T_c(B)$ phase boundary of superconducting niobium films with large area quasihexagonal hole arrays is reported. The hole arrays were patterned with microsphere photolithography. We investigate the perforated niobium films by means of electrical directed current transport measurements close to the transition temperature $T_c$ in perpendicularly applied magnetic fields. We find pronounced modulations of the critcal current with applied magnetic field, which we interpret as a consequence of commensurable states between the Abrikosov vortex lattice and the quasihexagonal pinning array. Furthermore, we observe Little-Parks oscillations in the critical temperature vs magnetic field.

description: We briefly review the approach to dipole-dipole scattering in holographic QCD developed in ARXIV:1202.0831. The Pomeron is modeled by exchanging closed strings between the dipoles and yields Regge behavior for the elastic amplitude. We calculate curvature corrections to this amplitude in both a conformal and confining background, identifying the holographic direction with the virtuality of the dipoles. The it wee-dipole density is related to the string tachyon diffusion in both virtuality and the transverse directions. We give an explicit derivation of the dipole saturation momentum both in the conformal and confining metric. Our holographic result for the dipole-dipole cross section and the it wee-dipole density in the conformal limit are shown to be identical in form to the BFKL pomeron result when the non-critical string transverse dimension is $D_\perp=3$. The total dipole-dipole cross section is compared to DIS data from HERA.

description: Autistic workers are often drawn to science, technology, engineering, arts, and math- related fields that rely on teamwork to produce innovative solutions. Yet, autistic traits like interpersonal communication and interaction differences can make teamwork challenging. Scientists and practitioners alike have not identified the unique needs of neurodiverse teams comprised of autistic and non-autistic members. A scoping review of 29 studies dispersed through psychology, vocational training, education, management, and disability journals revealed several themes: neurodiverse teamwork is an understudied yet extant phenomenon; the ‘autism advantage’ is lauded as a benefit to organizations but ignores the health and wellness cost to the individual; interpersonal communication is a challenge that is the responsibility of all team members; the effects of disclosure are complex; coworkers, leaders, and the organization have a role to play in neuroinclusivity. Theoretical and practical implications are described, and future research directions are identified.

Exploring the spaces between theory and practice : a framework to integrate a structural approach and social work activities
Creators: name: Peters, Heather Ione
Publisher: name: University of British Columbia
Year: 2012

description: This dissertation explores and examines the use of structural social work theory in practice, in order to better understand the processes involved in effectively integrating theory into practice. Structural social work theory was developed in Canada and has been in use for about 30 years. It is related to other progressive approaches such as radical, feminist, anti-racist, anti-oppressive and critical social work. The first chapter outlines the history of progressive social work and situates structural social work theory in this context. The literature review identifies issues and concerns with theory-practice integration specific to structural social work and other progressive social work theories, as well as theory-practice integration in general in the social work field. While the social work literature notes the problems with theory-practice integration, there are few studies examining the factors in the successful use of theory in practice. In addition, the literature tends to focus on individual factors in theory-practice integration, and there is limited research examining interactions between these factors. In-depth interviews were conducted with social work practitioners who utilized a structural social work approach in their practice. Follow-up interviews, a questionnaire and the analysis of documents mentioned by participants provided additional data. The findings demonstrate that participants’ use of structural social work theory in practice progressed through a series of six developmental stages. The stages began with the use of conventional social work activities, and moved to seeing the effects of structural oppression, forging alliances, encompassing structural goals into conventional social work activities, engaging in specifically structural activities, and culminated in adapting structural social work theory for use in practice. Participants’ use of the structural approach and the development through the stages were influenced by external contexts. The interactions between participants and the contexts, or structures, they encountered reflect the agency-structure dialectic found in structural social work theory.
Optimality, Objectives, and Trade-Offs in Motor Control under Uncertainty

description: Biological motor control involves multiple objectives and constraints. In this thesis, I investigated the influence of uncertainty on biological sensorimotor control and decision-making, considering various objectives. In the first study, I used a simple biped walking model simulation to study the control of a rhythmic movement under uncertainty. Uncertainty necessitates a more sophisticated form of motor control involving internal model and sensing, and their effective integration. The optimality of the neural pattern generator incorporating sensory information was shown to be dependent on the relative amount of physical disturbance and sensor noise. When the controller was optimized for state estimation, other objectives of improved energy efficiency, reduced variability, and reduced number of falls were also satisfied. In the second study, human participants performed regression and classification tasks on visually presented scatterplot data. The tasks involved a trade-off between acting on small but prevalent errors and acting on big but scarce errors. We used inverse optimization to characterize the loss function used by humans in these regression and classification tasks, and found that these loss functions change systematically as the data sparsity changed. Despite being highly variable, there were overall shifts towards compensating for prevalent small errors more when the sparsity of the visual data decreased. In the third study, I extended the pattern recognition tasks to include visually mediated force tracking. When participants tracked force targets with visual noise, we observed a slight yet consistent force tracking bias. This bias, which increased with noise, was not explained by commonly hypothesized objectives such as a tendency to reduce effort while regulating error. Additional experiments revealed that a model balancing error reduction and transition reduction tendencies effectively explained and predicted experimental data. Transition reduction tendency was further separated into recency bias and central tendency bias. Notably, this bias disappeared when the task became purely visual, suggesting that such biases could be task-dependent. These findings across the three studies provide useful insights into understanding how uncertainty changes objectives and their trade-offs in biological motor control, and in turn, results in a different control strategy and behaviors.
The Divergence of Reinforcement Learning Algorithms with Value-Iteration and Function Approximation

description: This paper gives specific divergence examples of value-iteration for several major Reinforcement Learning and Adaptive Dynamic Programming algorithms, when using a function approximator for the value function. These divergence examples differ from previous divergence examples in the literature, in that they are applicable for a greedy policy, i.e. in a "value iteration" scenario. Perhaps surprisingly, with a greedy policy, it is also possible to get divergence for the algorithms TD(1) and Sarsa(1). In addition to these divergences, we also achieve divergence for the Adaptive Dynamic Programming algorithms HDP, DHP and GDHP.

The results led to the interpretation of the q-deformation acting as a factor of disorder or impurity modifying the characteristics of a crystalline structure as, for example, in the case of semiconductors.

description: Xavier Vazquez’s human rights capstone project critically examines the current “warehouse industry” in the California Inland Empire and how this has come about through various social and political phenomenon such as land development, neighborhood displacement, and economics. Through interviews with local Inland Empire residents, Xavier traces how this region became known as a "wasteland" and became a place of modern colonization and a development project designed to uplift wealthier, often whiter, communities. Furthermore, he tackles the historical development of the Inland Empire into a “warehouse industry” and discusses its history to analyze the methodology of previous and current Inland Empire stakeholders, its disproportionate effect on minorities, and its consequences on its residents. Highlighting the lived experiences of relevant Inland Empire residents, such as warehouse workers, developers, and public officials, Xavier also provides discussion on the nuances of a warehouse economy and establishes recommendations regarding the future state of the Inland Empire to build a better home for future residents.

Exploring the Impact of YouthLink Calgary’s Crime Prevention Program on Youth

Publisher: name: Werklund School of Education
Year: 2023

description: Traditional methods of crime prevention have proven to be ineffective in reducing the occurrence of crime, especially among youth. Early intervention and educational crime prevention programs are recognized as more efficient forms of mediation than remedial or compensatory forms of reducing crime (Winterdyk, 2013). Community-based programs encourage youth to make positive life choices and increase the prospects of high-risk adolescents avoiding the criminal justice system all together (Vallee, 2010). The Calgary Police Interpretive Center, YouthLink program, focuses on crime prevention by empowering youth to make positive life choices, thus avoiding crime and the risk of being victimized. Crime-based prevention programs have struggled to provide evidence-based measures of their success through research. Through a partnership between the University of Calgary and the YouthLink Calgary this research study was developed to explore the impact of their one-day and week-long crime prevention programming on youth. The research design focuses on the short term impacts these programs have on youth participants, both from the perspective of the students and their teachers. A mixed methods approach was used in this study to collect and analyze both qualitative (open-ended survey questions) and quantitative (survey) data. Data was collected immediately after the completion of the program and again three months later. Findings showed students were comfortable and open to learning while attending the program. Pedagogical approaches such as authentic experiences and hands on investigative activities were helping students learn. Students were also applying what they are learning after attending and recalling messaging and strategies learned before making decisions. Findings also showed students were making safe decisions when faced with crime related pressures and challenges and were using tools and strategies they learned during the program. These findings highlight the short-term impacts of the YouthLink Calgary’s crime prevention and youth education program. This study has implications for crime-prevention programming and may be of interest to others engaged in developing or evaluating community based and crime prevent programs for youth.

description: The dark matter (DM) halos of field elliptical galaxies have not been well studied and their properties appear controversial. While some galaxies appear to be nearly devoid of DM, others show clear evidence of its presence. Furthermore, modified Netonian dynamics (MOND), which has been found to have predictive power in the domain of disk galaxies, has not yet been investigated for isolated elliptical galaxies. We study the kinematics of the isolated elliptical NGC 7507, which has been claimed as a clear example of DM presence in early-type galaxies. We obtained major and minor axis long-slit spectroscopy of NGC 7507 using the Gemini South telescope and deep imaging in Kron-Cousins R and Washington C using the CTIO/MOSAIC camera. Mean velocities, velocity dispersion and higher order moments are measured out to ~90 arcsec. The galaxy, although almost circular, has significant rotation along the minor axis and a rapidly declining velocity dispersion along both axes. Jeans models without DM provide an excellent representation of the data with a mass-to-light ratio (M/L) of 3.1 (R-band). The most massive Navarro-Frenk-White (NFW) halo the data allow has a virial mass of only 3.9+3.1-2.1E11 solar masses, although the data are more consistent with models that have a slight radial anisotropy, which implies the galaxy has an even lower DM halo mass of 2.2+2.0-1.2E11 solar masses. Modeling of the h_4 Gauss-Hermite coefficient is inconclusive but seems to be consistent with mild radial anisotropy. A cored logarithmic DM halo with parameters r0 = 7 kpc and v0 = 100 km/s can also reproduce the observed velocity dispersion profile. In conclusion, we cannot easily reproduce the previous findings of a predominance of DM in NGC 7507 within a simple spherical model. DM may be present, but only in conjunction with a strong radial anisotropy, for which there are some indications. (Abridged).

description: We consider the space $A(\mathbb T)$ of all continuous functions $f$ on the circle $\mathbb T$ such that the sequence of Fourier coefficients $\hat{f}=\{\hat{f}(k), ~k \in \mathbb Z\}$ belongs to $l^1(\mathbb Z)$. The norm on $A(\mathbb T)$ is defined by $\|f\|_{A(\mathbb T)}=\|\hat{f}\|_{l^1(\mathbb Z)}$. According to the known Beurling--Helson theorem, if $ϕ: \mathbb T\rightarrow\mathbb T$ is a continuous mapping such that $\|e^{inϕ}\|_{A(\mathbb T)}=O(1), ~n\in\mathbb Z,$ then $ϕ$ is linear. It was conjectured by Kahane that the same conclusion about $ϕ$ is true under the assumption that $\|e^{inϕ}\|_{A(\mathbb T)}=o(\log |n|)$. We show that if $\|e^{inϕ}\|_{A(\mathbb T)}=o((\log\log |n|/\log\log\log |n|)^{1/12})$ then $ϕ$ is linear.

Metaphors for thinking in modern Mandarin Chinese : a corpus study
Creators: name: Vorontsova, Iuliia
Publisher: name: University of British Columbia
Year: 2012

description: This paper studies the system of conceptual metaphors for thinking in Modern Mandarin Chinese. It looks into the frequency, types of metaphors and the ways they are realized in Language. The present research concentrates on five commonly used words for thinking, namely 想 xiang, 认 ren, 觉 jue, 觉得 juede, and 认为 renwei. The expressions about thinking used in the research are taken from spoken and non-spoken Modern Mandarin Chinese corpora. All examples were reviewed and metaphorical examples were identified and classified according to the metaphor types as distinguished by Lakoff and Johnson 1999. Series of research done in the sphere of cognitive science proved that some expressions about thinking are generally structured by conceptual metaphor based on the source domain of our embodied experience. However it was unclear how often metaphoric expressions are used in language compared to the non-metaphoric ones. The paper also looks into the difference in metaphor use in spoken and non-spoken Mandarin Chinese, metaphors of heart and head as the locus of thinking in Chinese. The research has shown approximately every fifth common expression about thinking is metaphorical, while container and path metaphor are most widely used to talk about thinking. Moreover, a large number of metaphors in expressions about thinking are realized through grammatical patterns, such as resultative constructions, and are generally not perceived as metaphorical. The results suggest that possibly different types of metaphor dominate in thinking expressions in Chinese and other languages. The research also indicates that in learning and teaching Chinese as a foreign language, conceptual metaphor awareness is necessary for grammar literacy and language proficiency, since a large number of fixed metaphoric constructions are realized in grammar. Generally the paper suggests that while most metaphors for thinking are universal, there are often differences in the frequency and the ways to use the metaphors. Thus such cultural variations can often result in different conceptualizations of an abstract concept or higher sensitivity to one type of metaphor but not the other.

description: We construct six-dimensional (1,0) superconformal models with non-abelian gauge couplings for multiple tensor multiplets. A crucial ingredient in the construction is the introduction of three-form gauge potentials which communicate degrees of freedom between the tensor multiplets and the Yang-Mills multiplet, but do not introduce additional degrees of freedom. Generically these models provide only equations of motions. For a subclass also a Lagrangian formulation exists, however it appears to exhibit indefinite metrics in the kinetic sector. We discuss several examples and analyze the excitation spectra in their supersymmetric vacua. In general, the models are perturbatively defined only in the spontaneously broken phase with the vev of the tensor multiplet scalars serving as the inverse coupling constants of the Yang-Mills multiplet. We briefly discuss the inclusion of hypermultiplets which complete the field content to that of superconformal (2,0) theories.

description: We report no-core solutions for properties of light nuclei with three different approaches in order to assess the accuracy and convergence rates of each method. Full configuration interaction (FCI), Monte Carlo shell model (MCSM) and no core full configuration (NCFC) approaches are solved separately for the ground state energy and other properties of seven light nuclei using the realistic JISP16 nucleon-nucleon interaction. The results are consistent among the different approaches. The methods differ significantly in how the required computational resources scale with increasing particle number for a given accuracy.

Search for a light pseudoscalar Higgs boson in the dimuon decay channel in pp collisions at sqrt(s) = 7 TeV

description: The dimuon invariant mass spectrum is searched in the range between 5.5 and 14 GeV for a light pseudoscalar Higgs boson "a", predicted in a number of new physics models, including the next-to-minimal supersymmetric standard model. The data sample used in the search corresponds to an integrated luminosity of 1.3 inverse femtobarns collected in pp collisions at sqrt(s) = 7 TeV with the CMS detector at the LHC. No excess is observed above the background predictions and upper limits are set on the cross section times branching fraction sigma times B(pp to "a" to an oppositely charged muon pair) in the range of 1.5-7.5 pb. These results improve on existing bounds on the "a" b-bbar coupling for m("a") < m(Upsilon(1S)) and are the first significant limits for m("a") > m(Upsilon(3S)). Constraints on the supersymmetric parameter space are presented in the context of the next-to-minimal model.

description: Secure multiparty computation (MPC) protocols enable multiple parties to collaborate on a computation using private inputs possessed by the different parties in the computation. At the same time, MPC protocols ensure that no participating party learns anything about the other parties’ private inputs beyond what they can infer from the computation’s output and their own inputs. MPC has wide ranging applications for privacy protecting systems. However, these systems have been plagued by limited performance, lack of scalability, and poor accuracy. In this thesis, we demonstrate several novel techniques for using distributed point functions (DPFs) in combination with MPC to obtain significant performance improvements in several different applications. Namely, using novel observations about the structure of the most efficient available DPF construction in the literature, we show that DPF keys from untrusted sources can be checked for correctness using an MPC protocol between the two key holders, with direct applications in sender-anonymous messaging. We expand these observations to produce the most efficient available method to evaluate piecewise-polynomial functions, also known as splines. The scalability and efficiency of this method allows for splines to be used for extremely high accuracy approximation of non-linear functions in MPC. Furthermore, the protocols proposed in this thesis far outperform prior solutions both in large-scale asymptotic measurements and in concrete benchmarks using high-performance software implementations at both small- and large-scale.

description: Building on the recent experimental achievements obtained with scanning electron microscopy on ultracold atoms, we study one-dimensional Bose gases in the crossover between the weakly (quasi-condensate) and the strongly interacting (Tonks-Girardeau) regime. We measure the temporal two-particle correlation function and compare it with calculations performed using the Time Evolving Block Decimation algorithm. More pronounced antibunching is observed when entering the more strongly interacting regime. Even though this mimics the onset of a fermionic behavior, we highlight that the exact and simple duality between 1D bosons and fermions does not hold when such dynamical response is probed. The onset of fermionization is also reflected in the density distribution, which we measure \emph{in situ} to extract the relevant parameters and to identify the different regimes. Our results show agreement between experiment and theory and give new insight into the dynamics of strongly correlated many-body systems.
Achieving a Low Carbon Economy in Nigeria via the Climate Change Mechanisms in the Paris Agreement

description: Nigeria is an energy insecure country and heavily relies on combustion of fossil fuels to provide power to meet its teeming population’s energy needs. The Nigerian government desires transitioning to a low carbon economy and securing access to clean power for its energy needs. However, Nigeria is not capable of independently financing its transition to a low carbon economy and would require aid to achieve this objective. Nevertheless, Nigeria has been overlooked by international actors capable of donating financial aid for climate action or collaborating with it on sustainable projects for a myriad of legal and non-legal considerations. The situation in Nigeria calls for urgent international intervention as modern science has linked the evident effects of climate change to carbon emissions from the combustion of fossil fuels. This thesis employs a doctrinal approach to identify the Market-Based and Non-Market approaches within the Paris Agreement as legal avenues Nigeria can explore to secure needed financial aid and support on climate action. These legal avenues also incorporate vital accountability measures to reassure international actors that the Nigerian government will undertake all necessary action to champion its long-awaited transition to a low carbon society. This thesis discusses practical ways the Market-Based and Non-Market approaches of the Paris Agreement ought to be implemented in Nigeria, within the legal ambits of Nigeria’s climate system and with due acknowledgement of its domestic realities. Furthermore, this thesis proffers recommendations regarding ideal regulatory overhauls the Nigerian government ought to implement to attract international financial aid and support on climate action.
Unearthing archives : an examination of documents generated in the course of archaeological fieldwork in Canada
Creators: name: McManus, Elizabeth Caitrin
Publisher: name: University of British Columbia
Year: 2012

description: Archaeology is a science that destroys the very evidence it wishes to study. Archaeologists must therefore clearly document all stages of their work. In Canada, legislation dictates that all artefacts recovered from archaeological activity must be deposited in an archaeological repository. In most cases only copies of a final report are required to be submitted to the provincial government department responsible for archaeology. This thesis sought to discover what happens to the documents generated from archaeological activity and whether they are of value to archaeologists. Data was collected through semi-structured interviews and surveys, and a review of current literature on archaeological practice. It was found that archaeologists place a high value on the documents they generate during an archaeological project and wish that they be kept in perpetuity; however, a lack of recordkeeping standards and of a relationship based on trust between archaeologists and archaeological repositories has led to poor record keeping practices amongst archaeologists in both academic and consulting environments and few transfers to repositories. The few documents that are transferred to repositories are rarely processed according to archival methodology for preservation and they are not easily accessible to researchers or the public. Thus, this thesis is concluded by a series of recommendations aimed to ensure that the documentary by-products of archaeological activity be maintained and preserved as reliable and authentic evidence of the projects to which they relate.
