title: The use of social media platforms for foreign language learning in adult and community education
Creators: name: Vogiatzis, Dimitrios
Publisher: name: The Open University
Year: 2023

description: The ubiquity of digital technologies in everyday life have transformed the landscape of education. Emerging digital tools are often used to facilitate teaching and learning in a range of ways, arguably providing opportunities for inclusion and access to diverse sources of information and knowledge. The advent of social media platforms like Facebook and WhatsApp has attracted scholarly attention both in terms of the ways in which people communicate in everyday life as well as in their potential in language learning settings. Although a lot of research has been conducted on the use of social media in higher education, there is no evidence on the impact of these digital platforms in the Adult and Community Learning (ACL) context. This thesis contributes to the under-researched field of ACL by investigating the use of Facebook and WhatsApp by two groups of language learners in an adult education centre in the UK. It explores the opportunities that social media (in this case, Facebook and WhatsApp) can provide in terms of student-to-student and teacher-to-student interaction and also points to their limitations. Following a case study design, pre- and post-questionnaires, online observation, and semi-structured interviews were used to elicit data for the study. A key methodological contribution of this thesis is the systematic combination of two analytical frameworks (i.e. the Community of Inquiry framework, and the framework for the analysis of sharing practices) to analyse teachers’ and learners’ online contributions. This study examines students’ perceptions of using these digital platforms for language learning purposes and provides an empirical account of the extent to which (and how) learners and teachers interact with each other in these online environments. The analysis pointed to a mismatch between students’ perceptions of the benefits of digital platforms for language learning and their online behaviour and foregrounded the importance of a set of contextual factors in the effective use of social media affordances for language learning.

description: The evolution equation for the shear is reobtained for a spherically symmetric anisotropic, viscous dissipative fluid distribution, which allows us to investigate conditions for the stability of the shear-free condition. The specific case of geodesic fluids is considered in detail, showing that the shear-free condition, in this particular case, may be unstable, the departure from the shear-free condition being controlled by the expansion scalar and a single scalar function defined in terms of the anisotropy of the pressure, the shear viscosity and the Weyl tensor or, alternatively, in terms of the anisotropy of the pressure, the dissipative variables and the energy density inhomogeneity.

Publisher: name: Unknown
Year: 2009
Subjects: Land Economics/Use

description: Introduction: The purpose of this paper is to provide farm-level information of the impact of recent policy changes on agriculture in Less Favoured Areas (LFAs). Our main contribution is the presentation of an integrated view of mixed impact of Single Farm Payment (SFP), the decoupling policy and Agri-Environmental Schemes (AESs) by examining farm-level financial conditions. The study reported here calculates not only the changes in agricultural incomes but also highlights changes in land use and livestock numbers that could influence the economy and environment of the countryside. The next section contains a brief review of the literature, followed by a concise description of our case study methodology in Northumberland, North East of England. The results of on-farm interviews are then examined focusing on changes in land use, labour, AESs and livestock numbers with reference to the policy changes.

From the more iconic to the less iconic linguistic form: morphological syntagms in Pāṇini
Creators: name: Pontillo, Tiziana
Publisher: name: Atti del sodalizio glottologico milanese
Year: 2019

description: Starting from Kastovsky’s definition of “morphological syntagm”, I try to understand whether any similarity exists between complex word forms (such as compounds and secondary derivatives) and the matching source-phrases which should be taken into account in the relevant formation-rules according to Pāṇini’s teaching. Thus, A 2.1.1 is interpreted and tested in a fresh manner, leading to the outline of a a scalar pattern of iconicity which encompasses the several outputs of the provisions it governs.

description: We calculate the expected branching fraction of the second-class-current decay tau --> pi eta' nu, motivated by a a recent experimental upper-limit determination of this quantity. The largest contribution to the branching fraction is due to the intermediate a0(980) scalar meson, assuming it is a $\bar ud$ state. Smaller contributions arise from a0(1450), rho(770), and rho(1450). Our calculated values are substantially below the experimental upper limit, and are smaller still if the a0(980) is a four-quark state, as often suggested. Thus, a precise measurement or tight upper limit has the potential to determine the nature of the a0(980), as well as search for new scalar interactions.

description: We investigate the phenomenology of general gauge mediation in the MSSM. We apply the strict definition of gauge mediated SUSY-breaking where B_mu is generated only through gauge interactions, and as a result is very close to zero at the messenger scale. In this setup tan beta is a prediction rather than an input. The input parameters are independent scales for the gaugino masses, the scalar masses and the messenger mass in accord with general gauge mediation. We investigate the spectra, the constraints on the parameter space from direct searches and indirect observables, as well as fine-tuning. The favoured region of parameter space includes and interpolates between non-split and mildly split SUSY, characteristic of ordinary gauge mediation and direct gauge mediation models, respectively.

Creators: name: Mann, Janelle

Publisher: name: Unknown
Year: 2009
Subjects: subject: Environmental Economics and Policy
subject: phosphorus
subject: nutrient management regulations
subject: manure application

description: Environmental concerns about phosphorus loadings in Lake Winnipeg and other water bodies have led to proposed phosphorus-based nutrient management regulations for the province of Manitoba (Canada), including maximum threshold levels for phosphorous on agricultural lands. The proposed regulations will require costly changes in the manure management practices of the provinceâ€™s pig farmers. This article focuses on the direct annual cost to the pig producers in the province of complying with the proposed regulations should they become law. A recent set of farm-level survey data provides a base for the analysis. A GIS data system is used to facilitate measurement of impacts at level of the individual producer which are aggregated to determine the added provincial cost. The estimated added annual cost to the Manitoba pig industry under a maximum threshold regulation of two-times phosphorus removal is 17.88 million dollars, representing 18% of the estimated annual 2005 net income accruing to pig producers in the province. The estimated added annual cost under a maximum threshold regulation of one-times phosphorus removal is 27.86 million dollars, representing 28% of the estimated annual 2005 net income accruing to pig producers in the province.

description: Flows of dense emulsions show many complex features among which long range nonlocal effects pose a problem for macroscopic characterization. In order to get around this problem, we study the flows of several dense emulsions in a wide-gap Couette geometry. We couple macroscopic rheometric experiments and local velocity measurements through MRI techniques. As concentration heterogeneities can be expected, we designed a method to measure the local droplet concentration in emulsions with a MRI device. In contrast to dense suspensions of rigid particles where very fast migration occurs under shear, we show that no migration takes place in dense emulsions even for strains as large as 100 000 in our systems. As a result of the absence of migration and of finite size effect, we are able to determine very precisely the local rheological behavior of several dense emulsions. As the materials are homogeneous, this behavior can also be inferred from purely macroscopic measurements. We thus suggest that properly analyzed purely macroscopic measurements in a wide-gap Couette geometry can be used as a tool to study the local constitutive laws of dense emulsions. All behaviors are basically consistent with Herschel-Bulkley laws of index 0.5, but discrepancies exist at the approach of the yield stress due to slow shear flows below the apparent yield stress in the case of a strongly adhesive emulsion. The existence of a constitutive law accounting for all flows contrasts with previous results obtained within a microchannel by Goyon et al. (2008): the use of a wide-gap Couette geometry is likely to prevent here from nonlocal finite size effects; it also contrasts with the observations of Bécu et al. (2006).
Magnetic Yang-Mills Theory as an Effective Field Theory of the Gluon Plasma
Creators: name: Baker, M.
Publisher: name: arXiv
Year: 2009
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We propose magnetic SU(N) pure gauge theory as an effective field theory describing the long distance nonperturbative magnetic response of the deconfined phase of Yang-Mills theory. The magnetic non-Abelian Lagrangian, unlike that of electrodynamics where there is exact electromagnetic duality, is not known explicitly, but here we regard the magnetic SU(N) Yang-Mills Lagrangian as the leading term in the long distance effective gauge theory of the plasma phase. In this treatment, which is applicable for a range of temperatures in the interval T_c < T < 3 T_c accessible in heavy ion experiments, formation of the magnetic energy profile around a spatial Wilson loop in the deconfined phase parallels the formation of an electric flux tube in the confined phase. We use the effective theory to calculate spatial Wilson loops and the magnetic charge density induced in the plasma by the corresponding color electric current loops. These calculations suggest that the deconfined phase of Yang-Mills theory has the properties of a closely-packed fluid of magnetically charged composite objects.

description: The patient’s pus stain showed unstained organisms in the Gram stain (see Fig. 1C
in the photo quiz), which were positive by acid-fast staining (see Fig. 1D in the
photo quiz). Tissue and pus specimens were cultured at 32°C by inoculating the
sediment on LJ solid medium and in a mycobacterial growth indicator tube (MGIT)
(Becton, Dickinson, Sparks, MD). The cultures grew acid-fast bacilli (AFB) after 4 weeks
for the pus specimen and 8 weeks for the tissue specimen. Two groups of mycobacterial
colonies were identified. The first group (at 4 weeks) contained colonies that were
creamy in color and turned yellow when exposed to light (photochromogenic), while
the second group of colonies (at 8 weeks) appeared yellow and rough, with a welldemarcated
edge. The organisms were later identified as Mycobacterium marinum and
M. ulcerans, respectively (1). DNA extracted from pus and tissue samples were evaluated
by PCR targeting the 16S rRNA gene and by the IS2404 insertion elements. PCR
targeting the 16S rRNA gene confirmed Mycobacterium species most closely matching
M. marinum and/or M. ulcerans. The sequences of the IS2404 amplicon were identical
to those from M. ulcerans. Coinfections due to M. marinum and M. ulcerans, thus, were
diagnosed based on cultures (M. marinum and M. ulcerans) and PCR primers specific for
M. ulcerans. M. marinum and M. ulcerans were subjected to antimicrobial susceptibility
testing (AST) using a broth microdilution susceptibility test (2), and both organisms
were susceptible to clarithromycin, doxycycline, moxifloxacin, and rifampin. The patient
was empirically treated with rifampin, clarithromycin, and streptomycin together with
multiple surgical debridements of his left index finger, which resulted in a significant
reduction of the inflammation and resolution of the abscess.
A philosophical interpretation of Judea Pearl's theory of causality
Creators: name: Stafford, J
Publisher: name: University Of Tasmania
Year: 2023

description: Judea Pearl has provided a book long treatment to the topic of causality from a formal and predominantly non-philosophical perspective. One of the main aims of Pearl's treatment is to increase the clarity of scientists' reasoning about problems involving causal relationships. I offer a philosophical interpretation of Judea Pearl's treatment of causality. I argue Pearl (2000a) articulates an analysis of causality in two distinct parts. I claim that Pearl unifies several of the key concepts of causality relevant to the epidemiological, economic, social and biological sciences on one part and that Pearl describes several general conditions characteristic of objective causal processes on the other. I label the first part Pearl's account of causal modelling and the second part Pearl's account of causal processes respectively. I find that Pearl's account of causal processes is of the greatest philosophical interest despite the fact that Pearl's account of causal modelling is the primary component of the overall treatment. I locate Pearl's account of causal modelling first within the recent philosophical literature on the nature of models and modelling practices before the literature on causation and explanation as has been the standard elsewhere. With some reservations I argue Pearl's views on objective constraints are consistent with a nomic view of causation. To focus my interpretation I discuss several philosophical criticisms of Pearl's account and argue that each one is misplaced when targeteq at the first part of the account and merely analogues to familiar problems of model interpretation and justification when targeted at the second. I conclude that Pearl's account provides good reason to re-sharpen the philosophical focus on what it is to give an analysis of causation.

We evaluate interaction correction $δG$ to Andreev conductance and demonstrate a close relation between Coulomb effects and shot noise in NS systems. In the diffusive limit doubling of both shot noise power and charge of the carriers yields $|δG|$ four times bigger than in the normal case. Our predictions can be directly tested in future experiments.

description: We report a moderate-depth (70 ksec), contiguous 0.7 sq.deg, Chandra survey, in the Lockman Hole Field of the Spitzer/SWIRE Legacy Survey coincident with a completed, ultra-deep VLA survey with deep optical and near-infrared imaging in-hand. The primary motivation is to distinguish starburst galaxies and AGN, including the significant, highly obscured (log N_H >23) subset. Chandra has detected 775 X-ray sources to a limiting broad band (0.3-8 keV) flux ~4E-16 erg/cm^2/s. We present the X-ray catalog, fluxes, hardness ratios and multi-wavelength fluxes. The log N vs. log S agrees with those of previous surveys covering similar flux ranges. The Chandra and Spitzer flux limits are well matched: 771 (99%) of the X-ray sources have IR or optical counterparts, and 333 have MIPS 24 um detections. There are 4 optical-only X-ray sources and 4 with no visible optical/IR counterpart. The very deep (~2.7 uJy rms) VLA data yields 251 (> 4 sigma) radio counterparts, 44% of the X-ray sources in the field. We confirm that the tendency for lower X-ray flux sources to be harder is primarily due to absorption. As expected, there is no correlation between observed IR and X-ray flux. Optically bright, Type 1 and red AGN lie in distinct regions of the IR vs X-ray flux plots, demonstrating the wide range of SEDs in this sample and providing the potential for classification/source selection. The classical definition of radio-loudness, R_L, is not effective at selecting strong radio sources for red and relatively optically faint AGN. Using the 24 um to radio flux ratio (q_24) results in the usual ~10% radio-loud AGN (13 of 147).

description: The main aim of the Water Framework Directive (WFD) is to improve the water quality in all waters in Europe and the target is described as â€œgood ecological statusâ€, which should be reached in all water bodies by 2015 and no later than 2027. In the paper some key issues regarding the economic analyses and choice of the most cost effective measures is described. Results from preliminary analysis made by Denmark, The Netherlands and the United Kingdom are described. The findings suggest that all three countries find it difficult to achieve the goals in 2015. Instead they will postpone parts of the implementation until after 2015 to reduce overall costs, but in the Netherlands the target will not be reached by 2027. The costs for the agricultural sector in the implementation of WFD are low in the Netherlands and moderate in United Kingdom and Denmark. In the Netherlands few agricultural measures are included, although most of the nutrient loss comes from agriculture. In United Kingdom N-loses will be reduced through Farming schemes and P-losses will be reduced by 50% through Water Protection Zones. In Denmark, the measures consist of set a side, catch crops and wetlands. It is likely that the loss of direct income for Danish farmers is partly financed through a reduction in the Single Payment Scheme. The implementation of WFD is important for European farmers and so participation will have a large impact on the results and costs experienced at the farm level.

description: European agricultural and environmental policy has evolved considerably over the last 15 years. In this paper the changes in farm businesses in an Environmentally Sensitive Area in England are evaluated based on two surveys with the same farmers at the start and end of this period. The rate of participation in the environmental scheme had increased significantly at a time when Government led goals in this area had developed and become more output focussed. A combination of policy, market and animal health status changes had encouraged a number to leave cattle production and though remaining with stock and grass they had decided against any extensive development in the direction of pluriactivity-with or without Government encouragement. This leaves the future of this group in some uncertainty with two significant forms of financial support, the environmental scheme and the Hill Farm Allowance due to close.

description: The objective of this study is to evaluate on-farm costs and benefits of adopting Beneficial Management Practices (BMPs) to improve water quality. BMPs tested include permanent cover, buffer strips, off-stream watering and fencing riparian areas. Farms in Lower Little Bow River watershed are very large and with relatively little debt. A stochastic and dynamic farm-level simulation model is developed to assess net farm benefits. Model results indicate that implementation of these BMPs significantly reduces farm cash flow. Depending on desired level of riparian protection, increasing calf productivity and/or improving pasture utilization might in theory off-set off-stream watering costs. Fencing cost is prohibitive. Given vagaries of the cattle business, uncertainty about international border closures, high cost of fencing and no clear on-farm benefits to adoption, financial incentives may be required for voluntary implementation.

description: Techniques of load flow and economic analysis are presented in this thesis. Methods of load flow solutions for an electricity system presented in this project are: direct and indirect. The iterative methods have been made up of: Gauss Seidel, Fast decoupled load flow and second order load flow methods. The rule of thumb in order to determine the losses per annum is also presented. The powerful software DAPPER is used to calculate load flow and voltage drop. Four methods of economic analysis are studied but the net present value method is used to find the optimum option due to the reason that it has gained widespread acceptance in Australia.

description: 1st Paragraph - Cash leasing and share leasing allocate risk very differently.With cash leasing, farmers assume all the risk because landlords get a fixed amount of money each year. Any profit the farmer earns on cash rented land is subject to variability in yields and prices. Yields are affected by a whole host of factors but most of these are weather driven. There are tools farmers can use to mitigate the effects of these risks, but the risks themselves are still present. Even with good risk management tools, farmers are likely to have variability in net income.

description: Organic milk production in New Zealand has expanded in recent years in response to increasing global demand for organic product. Most comparisons between organic and conventional dairying available in the literature are from Europe or North America where the conventional systems are more intensive than conventional systems in New Zealand. This paper compares the cost of production and profitability of certified organic and conventional dairy farming over five years of a Massey University system comparison trial. The difference between these pastoral farming systems was predicted to be less than that noted in the more intensive EU and the US dairy farming systems as fewer changes are required to achieve organic certification. However the results highlight the vulnerability of both pastoral systems to climatic variability and identify the additional risks of organic dairy systems.

description: We discuss the interplay of low-x physics and QCD scaling violations by extending the unified approach describing inclusive structure functions and diffractive production in $γ* p$ interactions proposed in previous papers, to large values of Q2. We describe the procedure of extracting, from the non-perturbative model, initial conditions for the QCD evolution that respect unitarity. Assuming Regge factorization of the diffractive structure function, a similar procedure is proposed for the calculation of hard diffraction. The results are in good agreement with experimental data on the proton structure function $F_2$ and the most recent data on the reduced diffractive cross section, $x_P σ_r^{\D(3)}$. Predictions for both $F_2$ and $F_L$ are presented in a wide kinematical range and compared to calculations within high-energy QCD.

The technical and economic aspects of power flow analysis
Creators: name: Nguyen, Thang Long
Publisher: name: University Of Tasmania
Year: 2023

description: Power Flow Analysis is basic to most studies of power systems. To analyze the power flow problem, the conventional approach is applied together with useful measures in power system studies : the numerical iterative techniques, the single-line diagram and the per-unit representation. This thesis deals with two inter-related aspects of power flow analysis - the technical and the economic. The methodology, the basic mathematical models and the major methods commonly used in each analysis are systematized in order to provide the theoretical foundation to the problem. The technical power flow and economic analysis is then applied to a system modelled on a simplified version of the practical power system of Tasmania, Australia. The application is performed with the use of digital computers, DAPPER software and MATLAB programming language for the technical analysis, and Excel spreadsheet software for the economic analysis.

The electronic bands, density of states, Fermi surfaces, atomic charges, together with Sommerfeld coefficients and molar Pauli paramagnetic susceptibility have been evaluated and discussed in comparison with oxyarsenide LaFeAsO - a parent phase for a new class of high-temperature (Tc about 26-56K) oxygen-containing FeAs superconductors. Similarity of our data for SrFeAsF and CaFeAsF with the band structure of oxygen-containing FeAs superconducting materials may be considered as theoretical background specifying the possibility of superconductivity in these oxygen-free systems.

Little is known about the comparative effectiveness of SDV versus high-dose influenza vaccine (HDV) in this population. Study Design: Cohort study using data from the US Renal Data System. Setting & Participants: 507,552 adults undergoing in-center maintenance hemodialysis between the 2010 to 2011 and 2014 to 2015 influenza seasons. Exposures: SDV and HDV. Outcomes: All-cause mortality, hospitalization due to influenza or pneumonia, and influenza-like illness during the influenza season. Analytic Approach: Patients were eligible for inclusion in multiple yearly cohorts; thus, our unit of analysis was the influenza patient-season. To examine the relationship between vaccine dose and effectiveness outcomes, we estimated risk differences and risk ratios using propensity score weighting of Kaplan-Meier functions, accounting for a wide range of patient- and facility-level characteristics. For nonmortality outcomes, we used competing-risk methods to account for the high mortality rate in the dialysis population. Results: Within 225,215 influenza patient-seasons among adults 65 years and older, 97.4% received SDV and 2.6% received HDV. We observed similar risk estimates for HDV and SDV recipients for mortality (risk difference, −0.08%; 95% CI, −0.85% to 0.80%), hospitalization due to influenza or pneumonia (risk difference, 0.15%; 95% CI, −0.69% to 0.93%), and influenza-like illness (risk difference, 0.00%; 95% CI, −1.50% to 1.08%). Our findings were similar among adults younger than 65 years, as well as within other subgroups defined by influenza season, age group, dialysis vintage, month of influenza vaccination, and vaccine valence. Limitations: Residual confounding and outcome misclassification. Conclusions: The HDV does not appear to provide additional protection beyond the SDV against all-cause mortality or influenza-related outcomes for adults undergoing hemodialysis. The additional cost and side effects associated with HDV should be considered when offering this vaccine. Future studies of HDV and other influenza vaccine strategies are warranted.

description: Health care−associated infections are an important source of morbidity
and mortality, with an estimated 1.7 million infections and
99,000 deaths annually in the United States.1 The major source of
health care−associated pathogens is thought to be the patient’s endogenous
flora, but an estimated 20% are acquired via other transmission
routes such as the environment, and 20%-40% are attributed to crosstransmission
via the contaminated hands of health care personnel.

description: Shukuri is a talented penman who was brought up in the school of classical speech art of the East and learned from the creative experiences of great poets such as Hafiz Sherozi, Alisher Navoi, Fuzuli. His skill is evident in following his predecessors and portraying his thoughts in various artistic mediums. In fact, the level of skill of any poet is judged by his new and impressive way of figuratively expressing his thoughts. When examining the poet's poems from the point of view of art, there is no doubt that he has a unique talent.

description: The stocker cattle grazing enterprise in the southern Plains regions of the United States is an important economic activity. The objective of the study was to determine the difference in the expected net return of a no-till forage establishment system relative to the intensive clean-till establishment system typically used in the region. Results show a reduction in fuel, lube, repairs, and labor expenses and fixed machinery costs of the conventional-till system outweigh the expenses associated with herbicide and herbicide application of the no-till system. Over the eight-year duration of the study, the no-till system realized an average of 11 greater days of grazing compared to the conventional till system. The expected net return of the no-till establishment system was $90 per hectare greater than the conventional-till system; however, this economic advantage is sensitive to relative differences in cattle performance between systems. It is also sensitive to the price of herbicide and price of diesel fuel.

description: Over the past decade, there is excellent evidence in the scientific literature that contaminated environmental surfaces and noncritical patient care items play an important role in the transmission of several key health care–associated pathogens including methicillin-resistant Staphylococcus aureus, vancomycin-resistant enterococci, Acinetobacter, norovirus, and Clostridium difficile. Thus, surface disinfection of noncritical environmental surfaces and medical devices is one of the infection prevention strategies to prevent pathogen transmission. This article will discuss a bundle approach to facilitate effective surface cleaning and disinfection in health care facilities. A bundle is a set of evidence-based practices, generally 3-5, that when performed collectively and reliably have been proven to improve patient outcomes. This bundle has 5 components and the science associated with each component will be addressed. These components are: creating evidence-based policies and procedures; selection of appropriate cleaning and disinfecting products; educating staff to include environmental services, patient equipment, and nursing; monitoring compliance (eg, thoroughness of cleaning, product use) with feedback (ie, just in time coaching); and implementing a “no touch” room decontamination technology and to ensure compliance for patients on contact and enteric precautions. This article will also discuss new technologies (eg, continuous room decontamination technology) that may enhance our infection prevention strategies in the future.
Renormalisability of noncommutative GUT inspired field theories with anomaly safe groups

description: We consider noncommutative GUT inspired field theories formulated within the enveloping-algebra formalism for anomaly safe compact simple gauge groups. Our theories have only gauge fields and fermions, and we compute the UV divergent part of the one-loop background-field effective action involving two fermionic fields at first order in the noncommutativity parameter theta. We show that, if the second-degree Casimir has the same value for all the irreps furnished by the fermionic multiplets of the model, then, that UV divergent part can be renormalised by carrying out multiplicative renormalisations of the coupling constant, theta and the fields, along with the inclusion of theta-dependent counterterms which vanish upon imposing the equations of motion. These theta-dependent counterterms have no physical effect since they vanish on-shell. This result along with the vanishing of the UV divergent part of the fermionic four-point functions leads to the unexpected conclusion that the one-loop matter sector of the background-field effective action of these theories is one-loop multiplicatively renormalisable on-shell. We also show that the background-field effective action of the gauge sector of the theories considered here receives no theta-dependent UV divergent contributions at one-loop. We thus conclude that these theories are on-shell one-loop multiplicatively renormalisable at first order in theta.

The tsimshian crest system : a study based on museum specimens and the Marius Barbeau and William Beynon field notes
Creators: name: Halpin, Marjorie Myers
Publisher: name: University of British Columbia

description: This thesis is about the relationship of art and society. Specifically, it investigates Tsimshian crest art and its relationship to social organization. The analytical framework is structural, with explanatory formulations derived in part from the writings of Claude Levi-Strauss and Victor Turner. The study is unusual in that it is based upon museum specimens and records, data not often perceived as amenable to treatment within the context of contemporary social anthropology. It is also the most systematic examination of Northwest Coast iconography yet undertaken. The data include the field notes of Marius Barbeau and William Beynon, collected from the Tsimshian between 1914 and 1957, and preserved in the National Museum of Man. These data were used to construct an iconographic framework or grid within which Tsimshian objects in museums can be identified as crests. The crest system was analyzed as a series of statements about Tsimshian social structure. There are several hundred distinct named crests in the Tsimshian system (these are listed in an appendix), which is considerably more elaborate than the crest systems of their neighbours, the Haida and Tlingit. This elaboration was principally produced by the application of a series of "operators" (attributes) to crest animals in order to produce new forms. Thus, the Haida had a single raven crest, while the Tsimshian had over a dozen (White Raven, Split Raven, All Copper Raven, etc.). Still other forms were produced by merging features of different animals into composite "monsters." This complexity of forms is related in the thesis to a parallel elaboration and complexity in social structure, notably the greater elaboration of ranking and chieftainship in Tsimshian society. An analytical distinction was developed between "crests of differentiation" and "crests of integration." Crests of differentiation are totemic; that is, they employ distinctions between natural species in order to express differences between human descent groups. Crests of integration are iconographically monsters, which blur the natural (species) distinctions upon which totemic systems are based, in order to express integrative tendencies in social organization at both clan and "tribal" levels. A sub-category of complex monster crests was defined and shown to be related to a cannibal theme in Tsimshian mythology. The cannibal was interpreted as a metaphor expressing the redistributive function of the chiefly role. Representations of complex monsters were found on totem poles, house front paintings, frontlets, and raven rattles (the face on its "stomach"). A number of these representations are illustrated. While the focus of the study is crest art, a non-crest iconographic system based on spirit (naxn>’x) names was also defined and illustrated. This iconographic system is presented as the first ethnographically substantiated interpretation of Tsimshian masks.

description: In recent years, cell therapy has emerged as a promising therapeutic strategy for Parkinson’s disease. To increase cell viability, biomaterials are used to facilitate cell deposition, through injection, to the site of interest. However, the existing cell delivery approaches have shown limited success in clinical translation.This study aims to develop a device for the delivery of a cell-embedded in situ forming hydrogel. Here, computational approaches on the delivery of collagen to the striatum are presented, to gain insight into different parameters affecting the delivery.

description: A pot trial was carried out to evaluate the effect of Chicken manure, Tithonia diversifolia and Albizzia spp on maize plant height and dry matter production at the University of Goroka in the Eastern Highlands Province of Papua New Guinea (PNG). Increasing levels of organic inputs (5, 10 & 20 t/ha) plus a control (0 t/ha) were used as treatments (10) replicated 3 times in completely randomized design. Experimental soil was analyzed for water soluble anions and cations. Application of organic inputs resulted in positive responses. All chicken manure levels and 20 t/ha level of Tithonia diversifolia resulted in highly significant maize plant heights and dry matter production compared to all other treatments. . Mean maize plant heights ranged from 34 cm (control) to 54 cm (20 t/ha chicken manure). Dry matter production followed a similar trend with figures ranging from 0.19 t/ha (control) to 0.63 t/ha (chicken manure 20 t/ha). The effectiveness of organic input followed the order: Chicken manure > Tithonia diversifolia > Albizzia > Control.
