Evaluation of a physical education programme for grade one blind and partially-sighted children in a residential school for the deaf and blind
Creators: name: Williams, Carol Inge
Publisher: name: University of British Columbia
Year: 2011

description: The purpose of the study was to evaluate the effects of a programme of physical education for Grade One blind and partially-sighted children at Jericho Hill School, the British Columbia Provincial Residential School for the Deaf and Blind. The programme instituted was devised by the author in a problem-solving, child-centered manner where the activities were performed at the level of interest and ability of the individual child. The programme included the following activities: 1. Orientation 2. Physical Education Activities: (a) Body awareness (b) Stretching, pulling, twisting (c) Small equipment (d) Large apparatus (e) Creative movements to music (f) Trampolining (g) Water activities (h) Outdoor running, walking (i) Visit to Santa Claus (j) Activities with a sighted class. The programme extended from September, 1965 to March, 1966 with two or three sessions per week lasting from one-half hour to three-quarters of an hour each. Three evaluative measures were used to assess the programme: 1. Objective scores from the pre- and post-programme tests were given where a numerical value could be assigned to these tests. 2. Film loops¹ of the objective test items were used to show pre-and post-programme performances. These were subjectively evaluated by eleven experts in the field of physical education. 3. The classroom teacher reported on her personal record of the effect of the programme on individual children and on the group as a whole. The improved objective test scores, the film loop evaluation by the physical education experts, and the subjective evaluation of the classroom teacher and the Vice-Principal of the Blind Department showed that the programme was successful in producing improvement in the children, especially in the areas of confidence and basic physical skill development. A film² was produced in conjunction with the programme but not as an actual part of the study, showing various activities performed by the children throughout the year. This 23 minute black and white 16 mm film was produced and titled by the author. ¹Stored in the Library of the School of Physical Education and Recreation, The University of British Columbia. ²"Learn to See", available from the Extension Department, The University of British Columbia.

description: Sparse coding--that is, modelling data vectors as sparse linear combinations of basis elements--is widely used in machine learning, neuroscience, signal processing, and statistics. This paper focuses on the large-scale matrix factorization problem that consists of learning the basis set, adapting it to specific data. Variations of this problem include dictionary learning in signal processing, non-negative matrix factorization and sparse principal component analysis. In this paper, we propose to address these tasks with a new online optimization algorithm, based on stochastic approximations, which scales up gracefully to large datasets with millions of training samples, and extends naturally to various matrix factorization formulations, making it suitable for a wide range of learning problems. A proof of convergence is presented, along with experiments with natural images and genomic data demonstrating that it leads to state-of-the-art performance in terms of speed and optimization for both small and large datasets.

description: Nowadays, a popular method used for additive watermarking is wide spread spectrum. It consists in adding a spread signal into the host document. This signal is obtained by the sum of a set of carrier vectors, which are modulated by the bits to be embedded. To extract these embedded bits, weighted correlations between the watermarked document and the carriers are computed. Unfortunately, even without any attack, the obtained set of bits can be corrupted due to the interference with the host signal (host interference) and also due to the interference with the others carriers (inter-symbols interference (ISI) due to the non-orthogonality of the carriers). Some recent watermarking algorithms deal with host interference using side informed methods, but inter-symbols interference problem is still open. In this paper, we deal with interference cancellation methods, and we propose to consider ISI as side information and to integrate it into the host signal. This leads to a great improvement of extraction performance in term of signal-to-noise ratio and/or watermark robustness.

description: The vibrational frequencies of atom to atom bonds within a molecule are a function of the bond energies. Each bond has its characteristic frequency, and most of these frequencies can be detected with the infrared spectrophotometer. When one compound reacts with another or is adsorbed on the surface of a solid, detectable frequency changes or shifts may occur. These changes or shifts yield valuable information about the bonds which are formed or broken.

description: The integrated branching fraction of the process $B\to X_s l^+l^-$ is dominated by resonance background from narrow charmonium states, such as $B\to X_sψ\to X_s l^+l^-$, which exceeds the non-resonant charm-loop contribution by two orders of magnitude. The origin of this fact is discussed in view of the general expectation of quark-hadron duality. The situation in $B\to X_s l^+l^-$ is contrasted with charm-penguin amplitudes in two-body hadronic B decays of the type $B\toππ$, for which it is demonstrated that resonance effects and the potentially non-perturbative $c\bar c$ threshold region do not invalidate the standard picture of QCD factorization. This holds irrespective of whether the charm quark is treated as a light or a heavy quark.

Bei heutigen Bestandsbauten ist vermutlich in den meisten Fällen ein hybrides Lüftungssystem im Einsatz. Als hybrides System gilt zum Beispiel die Kombination von Abluftventilatoren in den Nasszellen respektive einer Kochstellenentlüftung mit einer Fensterlüftung in den übrigen Räumen; unabhängig davon, wie die Nachströmung der Ersatzluft gelöst ist. Da diese Anlagen Teil der Planungsrealität sind, gleichzeitig aber keine Planungshilfen oder eine Norm existieren, besteht hier ein Bedarf. Ziel des Projektes ist daher, das aktuelle Wissen zu bündeln, Lücken zu identifizieren und zusammenzustellen. Damit wird die Basis für Planungsgrundlagen in Form einer SIA Norm zur hybriden Lüftung gelegt.

description: Rota--Baxter operators over groups have been recently defined in \cite{LHY2021}, and they share a close connection with skew braces, as demonstrated in \cite{VV2022}. In this paper, we classify all Rota--Baxter operators of weight 1 over the Heisenberg Lie algebra of dimension 3 by directly solving the operators defining equations. Using the fact that the exponential map from the Heisenberg Lie algebra to the Heisenberg Group is bijective, we induces these operators to the Heisenberg Group. Finally, we enumerate all skew left brace structures over the Heisenberg Group induced by these Rota--Baxter operators.

description: The Planck On-Fligh Forecaster (POFF) is a tool to predict when a position in the sky will be within a selected angular distance from any receiver direction of the Planck satellite according to its pre-programmed observational strategy. This tool has been developed in the framework of the Planck LFI Core Team activities, but it is now used by the whole collaboration. In this paper we will describe the tool and its applications to plan observations with other instruments of point sources which are expected to enhance the possibilities of scientific exploitation of the Planck satellite data, once they will be publicly available. Collecting simultaneous multi-frequency data, like those that can be planned with the POFF, will help, on one hand, to investigate variability of point sources and, on the other, to reconstruct point source spectral energy distributions on wide frequency ranges minimizing the effects due to source variability. POFF is a combination of IDL routines which combine the publicly available information about the Planck scanning strategy and focal plane shape in order to identify if a given (list of) position(s) can be observable by the satellite at a given frequency and/or by selected receivers in a given time range. The output can be displayed with the desired time resolution and selecting among various sorting options. The code is not a Planck product, but it has been validated within the Planck LFI pipeline. The code format and the large number of options make it flexible and suitable for many applications, allowing to get results quickly. POFF is currently successfully used to plan activities within the Planck collaboration, including observations with several ground-based facilities, and it is distributed outside it.

description: The global climate of #MeToo and #TimesUp has forced us to recognise that violence against women has a long and dark history that needs to be acknowledged. Antithetical to this are the number of crimes against women recorded by the India National Crime Record Bureau (thirty nine per hour) (NCRB, 2016). The brutal rape of Nirbhaya shocked countries world over. It forced Indians to take notice - this had more to do with the breeding of a culture of violence than a case of a one-off incident. In this context, the objective of this dissertation and its outcomes have been to expose a few examples of where this violence towards women potentially stems from. Within a research framework grounded in design and material praxis, this thesis used a narrative based enquiry along with embodied ways of knowing to develop a series of interventions that cite historical and contemporary examples. These informed three rounds of redesign of the well known game Snakes and Ladders. User participation and testing were used to refine schemas of chance to choice within the game. Throughout this design process I have aimed to challenge behaviors and provide spaces to have discussions about problematic biases that subjugate women. Moving forward this work will continue to be developed. It will shift, with care and attention, to India where it will be further developed to better reflect the nuances of the context it is meant for.
title: Salt Tolerance Studies of Selected Crop Plants
Creators: name: Funk, Cyril Reed
Publisher: name: Utah State University
Year: 1956

description: Extensive land areas in arid and semi-arid regions contain excessive amounts of salt which inhibit or prevent the growth of desirable crop plants. This problem is increasing with the development of extensive irrigation projects. The future of irrigation agriculture will depend upon the development and the utilization of means of (1) preventing salt accumulation, (2) reclaiming salted soils. and (3) making the best use of those soils which by reason of drainage problems, soil texture and permeability, poor quality irrigation water, etc. are unsuited for economic reclamation.
The utilization of land that is not feasible to completely reclaim, at least under present economic conditions, will depend upon the selection, development, and use of varieties and strains of crop plants which will produce economically under such conditions.
The objectives of this research are to (1) test on a preliminary basis the salt tolerance of a number of promising crop plant materials. (2) observe the effect of salt upon plant behavior and growth, and (3) develop various methods of evaluating plant materials for salt tolerance.

description: The sweet cherry crop has always been the number one fruit crop in Utah until the last three or four years when it shifted to second place due to severe spring frosts. However, the outlook for its continued success is still very good. Even though there are drawbacks such as virus infestations, spring frosts, nutritional disorders, cracking, doubling, and bird injury, new plantings are being made each year in each of the important fruit producing counties. Utah is also important in the national production of sweet cherries and is presently sixth in the nation.

description: Reconstructing natural language from non-invasive electroencephalography (EEG) holds great promise as a language decoding technology for brain-computer interfaces (BCIs). However, EEG-based language decoding is still in its nascent stages, facing several technical issues such as: 1) Absence of a hybrid strategy that can effectively integrate cross-modality (between EEG and text) self-learning with intra-modality self-reconstruction of EEG features or textual sequences; 2) Under-utilization of large language models (LLMs) to enhance EEG-based language decoding. To address above issues, we propose the Contrastive EEG-Text Masked Autoencoder (CET-MAE), a novel model that orchestrates compound self-supervised learning across and within EEG and text through a dedicated multi-stream encoder. Furthermore, we develop a framework called E2T-PTR (EEG-to-Text decoding using Pretrained Transferable Representations), which leverages pre-trained modules alongside the EEG stream from CET-MAE and further enables an LLM (specifically BART) to decode text from EEG sequences. Comprehensive experiments conducted on the popular text-evoked EEG database, ZuCo, demonstrate the superiority of E2T-PTR, which outperforms the state-of-the-art in ROUGE-1 F1 and BLEU-4 scores by 8.34% and 32.21%, respectively. These results indicate significant advancements in the field and underscores the proposed framework's potential to enable more powerful and widespread BCI applications.

description: The acceleration of protons and electrons in a reconnecting current sheet (RCS) is simulated with a particle-in-cell (PIC) 2D3V code for the proton-to-electron mass ratio of 100. The electro-magnetic configuration forming the RCS incorporates all three components of the magnetic field (including the guiding field) and a drifted electric field. PIC simulations reveal that there is a polarisation electric field that appears during acceleration owing to a separation of electrons from protons towards the midplane of the RCS. If the plasma density is low, the polarisation field is weak and the particle trajectories in the PIC simulations are similar to those in the test particle (TP) approach. For the higher plasma density the polarisation field is stronger and it affects the trajectories of protons by increasing their orbits during acceleration. This field also leads to a less asymmetrical abundances of ejected protons towards the midplane in comparison with the TP approach. For a given magnetic topology electrons in PIC simulations are ejected to the same semispace as protons, contrary to the TP results. This happens because the polarisation field extends far beyond the thickness of a current sheet. This field decelerates the electrons, which are initially ejected into the semispace opposite to the protons, returns them back to the RCS, and, eventually, leads to the electron ejection into the same semispace as protons. Energy distribution of the ejected electrons is rather wide and single-peak, contrary to the two-peak narrow-energy distribution obtained in the TP approach. In the case of a strong guiding field, the mean energy of the ejected electrons is found to be smaller than it is predicted analytically and by the TP simulations.

France and the Antarctic Treaty System
Creators: name: Sulikowski, CT
Publisher: name: University Of Tasmania
Year: 2023

description: France is a prominent player in international Antarctic affairs. As a claimant state, original signatory, and key player within all the Antarctic Treaty System (ATS) institutions, with an extensive environmental legacy, France has consistently occupied an influential role in the international Antarctica political arena. This thesis examines key instances of French cooperation in the ATS, and in doing so, addresses questions relating to the nature of a single state's cooperation within a multilateral treaty regime. It considers the factors that motivate French cooperation within the ATS, and the strategic focus setting for France's Antarctic agenda through examining two key questions: what are the drivers that have led to France undertaking increasing cooperative engagement within the ATS over the last decade? And, through what principal means is France pursuing cooperation within the ATS? International regime theory, and in particular, the insights from the concept of complex interdependence, provides the analytical framework, and more widely assists in our understanding of international cooperation. This thesis also considers relevant aspects of international environmental law relating to France's engagement in the ATS. Three empirical case studies covering scientific and technical cooperation, marine living resource management, and environmental protection in the Antarctic and Southern Ocean region, provide evidence that assists in identifying the key characteristics, and patterns of interaction that encourage and facilitate France's multi-¬¨‚â†‚ÄövÑv™‚ÄövÑv´level cooperation within the ATS, and that enhance our understanding of the contemporary cooperative trends of France as a key player within the ATS. France has maintained consistent engagement within the ATS following the entry into force of the Antarctic Treaty over fifty years ago, and has pursued a number of key policy objectives in order to achieve its Antarctic agenda. Several contributing factors are identified as influential in France's increasing cooperative behaviour within the ATS. France places significant emphasis on pursuing multilevel cooperative agreements within the ATS, particularly at the bilateral level.

description: The legal framework used by the Mormon pioneers to establish corporations was imported into early Utah as were many other institutional ideas, social customs, and economic principles used in establishing their Zion. To understand in some completeness the effect of the corporate organization in Territorial Utah it is requisite that we first understand what constituted a corporation at that time and how this device was applied to the formation of business enterprises. What follows is a brief discussion of the development of the characteristics of the corporate organization from its origin to its implementation in early Utah.

description: The 197Au(gamma,n) reaction is used as an activation standard for photodisintegration studies on astrophysically relevant nuclei. At the bremsstrahlung facility of the superconducting electron accelerator ELBE (Electron Linear accelerator of high Brilliance and low Emittance) of Forschungszentrum Dresden-Rossendorf, photoactivation measurements on 197Au have been performed with bremsstrahlung endpoint energies from 8.0 to 15.5 MeV. The measured activation yield is compared with previous experiments as well as with calculations using Hauser-Feshbach statistical models. It is shown that the experimental data are best described by a two-Lorentzian parametrization with taking the axial deformation of 197Au into account. The experimental 197Au(gamma,n) reaction yield measured at ELBE via the photoactivation method is found to be consistent with previous experimental data using photon scattering or neutron detection methods.

description: HR8799 is a nearby A-type star with a debris disk and three planetary candidates recently imaged directly. We undertake a coherent analysis of various portions of observational data on all known components of the system. The goal is to elucidate the architecture and evolutionary status of the system. We try to further constrain the age and orientation of the system, orbits and masses of the companions, as well as the location of dust. From the high luminosity of debris dust and dynamical constraints, we argue for a rather young system's age of <50Myr. The system must be seen nearly, but not exactly, pole-on. Our analysis of the stellar rotational velocity yields an inclination of 13-30deg, whereas i>20deg is needed for the system to be dynamically stable, which suggests a probable inclination range of 20-30deg. The spectral energy distribution is naturally reproduced with two dust rings associated with two planetesimal belts. The inner "asteroid belt" is located at ~10AU inside the orbit of the innermost companion and a "Kuiper belt" at >100AU is just exterior to the orbit of the outermost companion. The dust masses in the inner and outer ring are estimated to be ~1E-05 and 4E-02 M_earth, respectively. We show that all three planetary candidates may be stable in the mass range suggested in the discovery paper by Marois et al. 2008 (between 5 and 13 Jupiter masses), but only for some of all possible orientations. Stable orbits imply a double (4:2:1) mean-motion resonance between all three companions. We finally show that in the cases where the companions themselves are orbitally stable, the dust-producing planetesimal belts are also stable against planetary perturbations.

description: Using the coherent-potential approximation, we have studied the effects of excess Fe, Se-deficiency, and substitutions of S, Te on Se sub-lattice and Co, Ni and Cu on Fe sub-lattice in FeSe. Our results show that (i) a small amount of excess Fe substantially disorders the Fe-derived bands while Se-deficiency affects mainly the Se-derived bands, (ii) the substitution of S or Te enhances the possibility of Fermi surface nesting, specially in FeSe$_{0.5}$Te$_{0.5}$, in spite of disordering the Se-derived bands, (iii) the electron doping through Co, Ni or Cu disorders the system and pushes down the Fe-derived bands, thereby destroying the possibility of Fermi surface nesting. A comparison of these results with the rigid-band, virtual-crystal and supercell approximations reveals the importance of describing disorder with the coherent-potential approximation.

description: It is widely acknowledged that environmental issues are complicated – that the means we use to try and address them are knotted affairs made up of many, many complicated threads. Too often the response to this tangle is avoidance and denial. Arguably, unsustainable human behaviour patterns are a significant barrier to addressing environmental concerns. This thesis details a design research approach considers approaches for behaviour change through interaction design and personal storytelling. The aim throughout has been to uncover new opportunities that could potentially provoke: environmental awareness, motivation towards changed behaviours, citizen agency. Environmental researchers are continuously analysing and describing environmental problems. Dissemination of this information is often seen as the main means to not only prove and demonstrate the issues but also to provide evidence that might change our current unsustainable living patterns. Social Media, documentaries, and news reporting provide a plethora of images, scientific facts and statistics about the issues. These unfortunately are not always effective – rather than motivating people to act - they often provoke responses such as fear, shame and consequent inaction. Acknowledging that objective, rational evidence does not necessarily impact human behavior, this body of work looks to narrative and interactive approaches as a means to invite people to consider environmental problems on a more personalized level. A key goal of my work has been to create means for enhancing and appreciating people’s experiences with nature - to provide outlets for people to share and reconsider their relations with the environment. By engaging people with their own personal stories or memories related to nature, I have sought to explore means to merge people’s collective memory of nature. Digital strategies that are commonly used in digital marketing campaigns aimed towards consumer agendas have been co-opted and revamped for an alternate purpose; to provide means for people to consider and respond with more motivation towards care for the environment. To that end, an open-ended, generative citizen design research tool intended to widen the perception of the use of interactive platforms for pro-environmental research practices was developed.

description: We propose a holographic tachyon model of dark energy with interaction between the components of the dark sector. The correspondence between the tachyon field and the holographic dark energy densities allows the reconstruction of the potential and the dynamics of the tachyon scalar field in a flat Friedmann-Robertson-Walker universe. We show that this model can describe the observed accelerated expansion of our universe with a parameter space given by the most recent observational results.

title: Studies on the Relationship of Moisture Content to Threshability and Viability of Pea Seeds
Creators: name: Roquia Y Dulalas, Filixberto
Publisher: name: Utah State University
Year: 1960

description: When in commercial practice seed peas (Pisum sativum) are harvested, the vines are cut and windrowed or bunched and allowed to cure for a week or longer, depending upon the moisture content of the crop and weather conditions. The sooner the crop can be threshed, the less is the chance of loss caused by rain and the often-necessary attendant operation of turning the windrow or bunch to facilitate drying. In general, growers wait until the vines, pods, and seeds are quite dry. To what extent this is necessary is not known.
Ultrastructure of the rostral sensory organs of the water bug, Cenocorixa bifida (Hungerford), (Hemiptera)
Creators: name: Lo, S. Esther
Publisher: name: University of British Columbia

description: The sensory organs in the transverse grooves of the dorsal labium of the water bug, Cenocorixa bifida, (Hungerford) (Hemiptera) were studied with the electron microscope. It was found that each sense organ is supplied by a single, bipolar neuron, which, together with its sheath cell, forms a sensory unit. The dendrite of the neuron is modified into various structures along its length; it has a root system, two basal bodies, and an axial filament complex. These structures are characteristic of many mechanoreceptors and chemoreceptors in insects. The sheath cell surrounding the dendrite possesses many characteristic fine structures, such as the desmosomes and the microtubules. According to their ultrastructure and their location near the mouth opening, it is most likely that these sensory organs are chemoreceptors. The significance of the presence of the ciliary regions in the dendrites of these organs is suggested to be related to the regeneration of the distal portion of the dendrite which may be torn off during the process of moulting. The axial filament complex may also serve as an internal support in the dendrite.

description: The tip of the red giant branch (TRGB) method provides one of the most accurate and precise means of measuring the distances to nearby galaxies. Here we present a multi-wavelength, VIJHK absolute calibration of the TRGB based on observations of TRGB stars in the Large Magellanic Cloud (LMC), grounded on a geometric distance, determined by detached eclipsing binaries (DEBs). This paper presents a more detailed description of the method first presented by Freedman et al. for measuring corrections for the total line-of-sight extinction and reddening to the LMC. In this method, we use a differential comparison of the red giant population in the LMC, first with red giants in the Local Group galaxy IC 1613, and then with those in the Small Magellanic Cloud (SMC). As a consistency check, we derive an independent calibration of the TRGB sequence using the SMC alone, invoking its geometric distance also calibrated by DEBs. An additional consistency check comes from near-infrared observations of Galactic globular clusters covering a wide range of metallicities. In all cases we find excellent agreement in the zero-point calibration. We then examine the recent claims by Yuan et al., demonstrating that, in the case of the SMC, they corrected for extinction alone while neglecting the essential correction for reddening. In the case of IC 1613, we show that their analysis contains an incorrect treatment of (over-correction for) metallicity. Using our revised (and direct) measurement of the LMC TRGB extinction, we find a value of H0 = 69.6 ± 0.8 (±1.1% stat) ± 1.7 (±2.4% sys) km s−1 Mpc−1.
title: Selected Physio-Chemical, Microbiological, and Agronomical Studies on the Controlled Atmosphere Storage of Sugarbeet (Beta Vulgaris) Roots
Creators: name: Karnik, Vinod V.
Publisher: name: Utah State University
Year: 1970

description: The post-harvest physiology of sugarbeet (Beta vulgaris) roots was studied during controlled atmosphere (CA) storage at 35° and 50°F. Zero, 3, 6 and 10% carbon dioxide and 5% oxygen concentrations were employed to investigate the most beneficial concentrations of gases. Under the experimental conditions beets were stored successfully for 200 days. The maximum beneficial effects of CA were observed under 6% carbon dioxide and 5% oxygen at 35°F. Regardless of storage temperatures , sucrose retention was highest in the beets stored under CA, compared to conventional refrigeration (CR). Other beneficial effects include less hydrolysis of sucrose to reducing sugars and a decrease in raffinose accumulation. Fungal growth and sprouting were also inhibited significantly, under CA.
In the second phase of the studies, investigations were conducted on sugarbeets to study the effects of different levels of nitrogen fertilizer on the optimum CA storage at 40°F. Regardless of the level of nitrogen fertilization, the beets stored under CA demonstrated beneficial effects as described earlier. In addition, respiration, measured on the whole beets, and amino nitrogen content of the beets were lower in the CA-stored beets than those stored under CR. Accumulation of citric acid and succinic acid was significant in the CA-stored beets.
title: Catalytic Effect of Soil Components on the Nitrite Transformation in Buffer Acid Solutions

description: Nitrite decomposition in buffer solutions of pH 3, 4, and 5 was observed to be a first order reaction with rate constants (k) 6.39 x 10-3, 1.15 x 10-3, and 0. 17 x 10-3, respectively . When 10 grams of two different soils were introduced, the reaction was catalyzed in all three pH conditions studied . This effect, however, was more pronounced in pH 5.
When 10 grams of soil were introduced, all the added nitrite was not recovered. The deficit ranged from 17 to 30 parts per million when 150 parts per million nitrite nitrogen was added and allowed to react for 6 hours. The deficits seemed to increase when the incubated soil samples were used. The major portion of the deficit was suspected to be due to the formation of N2 gas.
The effect of three amino acids was studied on the nitrite decomposition. Tryptophan and tyrosine increased the deficit whereas cystine did not have any effect.

description: In this series of papers we examine magnetic reconnection in a domain where the magnetic field does not vanish and the non-ideal region is localised in space. In a previous paper we presented a technique for obtaining analytical solutions to the stationary resistive MHD equations in such a situation and examined specific examples of non-ideal reconnective solutions. Here we further develop the model, noting that certain ideal solutions may be superimposed onto the fundamental non-ideal solutions and examining the effect of imposing various such flows. Significant implications are found for the evolution of magnetic flux in the reconnection process. It is shown that, in contrast to the two-dimensional case, in three-dimensions there is a very wide variety of physically different steady reconnection solutions.

The evolution of subject approaches to innovation measurement, and implications for new innovation indicators
Creators: name: O'Brien, KR
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis addresses a need for further evaluation of existing and new innovation survey indicators, which now provide an important evidence base informing better policy approaches. The research focus is on indicators produced from large scale, economy-wide innovation surveys, which collect firm-level data, and move beyond traditional R&D, patent, and bibliometric approaches by providing a direct, 'subject' approach to measurement. Such surveys are conducted in approximately 80 countries, producing numerous indicators, though many portray counterintuitive results, and are subject to various shortcomings. Consequently, this study seeks to explore how new indicators can improve understanding of innovation. Three indicator categories are assessed, using microdata from two iterations of a large regional innovation survey, the Tasmanian Innovation Census (TIC). Results examine three degrees of innovation novelty, and show that R&D activity and intensity provide good measures of innovation capability. Complex 'mode' indicators reveal the distribution of innovation characteristics at a 'system' level, across sectors, and for firms of different sizes, with linear, chain-link and systems theories all underpinning selected indicators. Using panel data, 'output' mode indicators reveal specific movement of both innovative and non-innovative firms between four innovation modes, providing a dynamic understanding of capability development and erosion over time, and suggesting that innovation capability for the most part develops cumulatively. Innovation based on diffusion is shown as most common in services. Composite indicator results provide a simple, visual picture of sectoral innovation performance, demonstrating usefulness beyond the typical macro-level of analysis. Results and discussion expose issues around theory, policy and practice with implications for related future research, including a need for further work to standardise different indicators for degrees of novelty and capability, and for research to understand the links between innovation modes and economic outcomes.
title: Resistance to and Transmission of Witches' Broom and Comparative Yields of Alfalfa Varieties in the Uintah Basin, Utah
Creators: name: Glover, David Val
Publisher: name: Utah State University
Year: 1959

description: Alfalfa is the most important forage crop in Utah. It is of particular importance to the Uintah Basin, Utah area where alfalfa hay and seed production are major sources of agricultural income. This crop owes much of its popularity to the fact that it will normally produce large yields of good forage on land which is unsuited to more intensive cultivation. In many cases it is impractical to advocate disease control practices which involve extra labor or expense and as a result most diseases of alfalfa, if controlled at all, are controlled by the use of resistant varieties.
During the past few years alfalfa witches' broom has become detrimental in the Uintah Basin area. This disease shortens the length of life of alfalfa stands and reduces the yield. Some diseased stands are killed out in a period of three years. It is difficult and expensive to reestablish alfalfa in this area where water supplies are usually low. Therefore, it is imperative that alfalfa stands remain in production for several years. These problems justify a study to find resistance to alfalfa witches' broom.
The objectives of this study are to select varieties of alfalfa which are resistant to alfalfa witches' broom in the Uintah Basin area, to select varieties of alfalfa which are best adapted to the area for high yield per acre, to determine which of a few insects tested are responsible for transmission of alfalfa witches' broom virus, and to determine if certain dodder species (Cuscuta spp.) act as transmission bridges for alfalfa witches' broom.
