description: Following Argentina’s seizure of the Falkland Islands and South Georgia on 2 and 3 April 1982, the United Kingdom’s military response to reclaim these overseas territories was the launching of a large maritime expeditionary operation extending over 8,000 miles into the harsh South Atlantic. As part of this challenging military undertaking, an extensive naval Task Force was assembled and despatched to the theatre of operations. Since the greatest threat to the Task Force would come from the numerically superior Argentine aircraft based on the South American mainland, air power would play a critical role in the successful prosecution of Operation Corporate. However, geography precluded the continuous and effective involvement by land-based aircraft of the Royal Air Force in the South Atlantic. Therefore, the task of providing the U.K.’s maritime expeditionary operation with the requisite air power fell to a small number of carrier-based fixed-wing aircraft. In total, 28 Sea Harriers of the RN’s Fleet Air Arm and ten Harrier GR.3s of the RAF carried aboard two small, non-fleet aircraft carriers were called upon to support Operation Corporate. By 14 June 1982, Argentine forces on the Falklands surrendered to the U.K., thus bringing to a close a unique military campaign at the bottom of the world. This thesis argues that, despite its inability to achieve permanent air supremacy or superiority, RN and RAF sea-based air power during the 1982 Falklands War was nevertheless a crucial contributing factor in the victory over Argentina due to its effective support of the U.K.'s maritime expeditionary operation.

description: In the course of the XMM-Newton survey of the Small Magellanic Cloud (SMC), two new bright X-ray sources were discovered exhibiting the spectral characteris- tics of High Mass X-ray Binaries - but revealing only weak evidence for pulsations in just one of the objects(at 153s in XMMUJ010743.1-715953). The accurate X- ray source locations permit the identification of these X-ray source with Be stars, thereby strongly suggesting these systems are new Be/X-ray binaries. From blue spectra the proposed classification for XMMUJ010633.1-731543 is B0.5-1Ve and for XMMUJ010743.1-715953 it is B2IV-Ve.

description: In this thesis a new six-stage prospect analysis and development methodology (PADEM) is discussed. Tools are developed in this work to assist with several stages of the PADEM including: prospect type-curve generation; prospect screening; exploration and pilot location selection. The tools developed in this work couple flow regime analysis and an analytical simulator with Monte Carlo simulation and economics to account for risk and uncertainty, while allowing direct comparison of prospect areas. Validating examples of each tool are given, using both simulated and field data. In addition, material balance techniques for shale gas are investigated with application to both static and flowing material balance for two conceptual gas storage models. A new material balance, which treats free and adsorbed gas as dependent components of gas-in-place, and a new transient productivity index, which is used to correctly identifying boundary-dominated flow in flowing material balance analysis, are also derived and tested.

description: There has been a rise in recent years in the number of women choosing to have a child without the involvement of a partner. These women, often referred to as ‘single mothers by choice’ or ‘choice mothers’, differ from single mothers who find themselves parenting alone following divorce, separation or unexpected pregnancy. This study delineates the experience of choosing single motherhood utilizing medically assisted donor insemination. I conducted 32 qualitative interviews focused on experiences of mothering and motherhood and reproductive decision-making. A grounded theory analysis revealed that for this sample, these women carefully craft a story to share with others explaining their decision. This story was influenced by the larger social discourses of “good” and “bad” mothering, “good” and “bad” female sexuality. These results give a new face and voice to the single mother, expanding our understanding of postmodern families.
Managing Dual Relationships in Rural and Remote Practice Settings

description: In social work in Ontario, a dual relationship exists when a social worker or social service worker, in addition to the professional relationship, has one or more other relationships with a client. Traditionally, dual relationships have been thought to be a circumstance where boundary violations, coercion, exploitation, or other misuse of power might take place. Social work codes of ethics/standards of practice, therefore, recommend avoiding dual relationships whenever possible. One practice setting where this is not always possible, however, is in rural and remote communities where, in fact, workers are often required to manage dual relationships as part of their day-to-day practice. To provide a better understanding of how non-sexual dual relationships are being managed in these communities there was a clear need for research grounded in social workers’ first-hand experiences with the process. Through the use of qualitative inquiry and grounded theory methodology, this study interviewed 25 social workers and social service workers familiar with rural and remote practice about their professional experiences with dual relationships. Specifically, the study explored the process of managing dual relationships in social work and social service work in small rural and remote communities. From the data/findings a substantive theory emerged that suggests that managing dual relationships in these practice settings is, in large part, an informal, emotional/intuitive process informed by workers’ subjective personal experiences, personal values/beliefs, and personal interpretations of codes and policy, as well as by community and agency expectation.

description: All organisms must simultaneously tolerate the environment and access limiting resources if they are to persist. Approaches to understanding abiotic filtering and competitive interactions have generally been developed independently. Consequently, integrating those factors to predict species abundances and community structure remains an unresolved challenge. We introduce a new synthetic framework that models both abiotic filtering and competition by using functional traits. First, our framework estimates species carrying capacities along abiotic gradients. Second, it estimates pairwise competitive interactions as a function of species trait differences. Applied to the study of a complex wetland community, our combined approach more than doubles the explained variance of species abundances compared to a model of abiotic tolerances alone. Trait-based integration of competitive interactions and abiotic filtering improves our ability to predict species abundances, bringing us closer to more accurate predictions of biodiversity structure in a changing world.

description: Research on assessing supervisees’ professional development (PD) has been primarily focused on either exploring subjective experiences or refining objective aspects of professional competence. As a complement, this study takes a situated/dialogical approach to explore how PD assessments are transacted and conversationally accomplished in actual supervision practice (i.e., how supervisory dyads bring about shared understandings vis-à-vis the supervisee’s PD through supervisory talk). Informed by Practice Theory and Ethnomethodology, I explore episodes of supervisory talk that four supervisory dyads regarded as significant to the supervisees’ PD (i.e., significant episodes). My focal discursive analysis of six significant episodes examines how participant supervisory dyads express, recognize, account for, negotiate and eventually agree upon relevant aspects of supervisees’ PD. I describe five “big” Practices/Outcomes, and three clusters of “small” conversational practices, through which participants negotiated their understandings of supervisees’ PD. I further suggest that PD assessments are ubiquitous, negotiated, and reflexive in the supervisory process. Finally, I discuss implications for supervision theory, research, and practice.

description: In this paper we present a high-resolution spectroscopic analysis of the chemically peculiar star HD207561. During a survey programme to search for new roAp stars in the Northern hemisphere, Joshi et al. (2006) observed significant photometric variability on two consecutive nights in the year 2000. The amplitude spectra of the light curves obtained on these two nights showed oscillations with a frequency of 2.79 mHz [P~6-min]. However, subsequent follow-up observations could not confirm any rapid variability. In order to determine the spectroscopic nature of HD207561, high-resolution spectroscopic and spectro-polarimetric observations were carried out. A reasonable fit of the calculated Hbeta line profile to the observed one yields the effective temperature (Teff) and surface gravity (log g) as 7300 K and 3.7 dex, respectively. The derived projected rotational velocity (vsin i) for HD207561 is 74 km/sec indicative of a relatively fast rotator. The position of HD207561 in the H-R diagram implies that this is slightly evolved from the main-sequence and located well within the delta-Scuti instability strip. The abundance analysis indicates the star has slight under-abundances of Ca and Sc and mild over-abundances of iron-peak elements. The spectro-polarimetric study of HD207561 shows that the effective magnetic field is within the observational error of 100 gauss (G). The spectroscopic analysis revealed that the star has most of the characteristics similar to an Am star, rather than an Ap star, and that it lies in the delta-Scuti instability strip; hence roAp pulsations are not expected in HD207561, but low-overtone modes might be excited.

description: Cotton growers in parts of the arid Southwest can raise their profits by switching to water-saving drip irrigation. In experiments, it has cut water use by up to 50 percent and raised cotton yields by a half bale per acre and more in some locations. New detailed data in this report show that the costs of operating a drip system on a cotton farm in central Arizona are comparable with the costs of operating a conventional furrow irrigation system. The analysis permits an assessment of the profitability of drip-irrigated cotton in the Southwest.
The secondary maximum of T CrB caused by irradiation of the red giant by a cooling white dwarf

description: Both the 1866 and 1946 outbursts of the recurrent symbiotic nova T CrB have displayed a mysterious secondary maximum peaking in brightness ~5 months past the primary one. Common to all previous modeling attempts was the rejection of plain irradiation of the red giant (RG), on the basis that the secondary maximum of T CrB would have been out of phase with the transit at superior conjunction of the RG. Implicit to this line of reasoning is the assumption of a constant temperature for the white dwarf (WD) irradiating the red giant. I show by radiative modeling that irradiation of the RG by a cooling WD nicely reproduces the photometric evolution of the secondary maximum, both in terms of brightness and color, removes the phasing offset, and provides a straightforward explanation that will be easy to test at the next and imminent outburst.

Arnold's strange duality list), thus extending the methods of 1006.3435 to singularities which are not the direct sum of minimal ones. In particular, we compute their BPS spectra in several `strongly coupled' chambers. From the TBA side, we construct ten new periodic Y-systems, providing additional evidence for the existence of a periodic Y-system for each isolated quasi-homogeneous singularity with $\hat c<2$ (more generally, for each N=2 superconformal theory with a finite BPS chamber whose chiral primaries have dimensions of the form N/l).

The recruitment and retention of community health workers in small cities, towns, and rural communities
Creators: name: Sharman, Zena Catherine
Publisher: name: University of British Columbia
Year: 2010

description: This study focused on the recruitment and retention of community health workers (CHWs) who work outside of large urban centres in small cities, towns, and rural communities in Canada. The study had three objectives: (1) to describe what CHWs working in small cities, towns, and rural communities have to say about their jobs, their working conditions, and their roles within the health care system; (2) to investigate these CHWs’ experiences of, and motivations for, pursuing a career in the home support sector; and (3) to develop recommendations to inform the design of policies and programs for the recruitment and retention of CHWs in small cities, towns, and rural communities. The study employed a qualitative research design informed by a feminist approach to health services research aimed at fostering “bottom-up” policy development informed by the perspectives of marginalized health care workers. The research process was carried out in partnership with a regional health authority in British Columbia, Canada. Data collection took place in four Vancouver Island communities: Campbell River, Parksville, Port Alberni and Port Hardy. Semi-structured interviews were conducted with 32 participants across the four study communities. The majority of the participants (n = 17) were unionized CHWs. The other respondents included nurses, managers, team leaders, and a scheduler. All interviews were transcribed and thematically analyzed. Study findings were later reported back to and validated by the participants. The study found that CHWs in the study communities performed a wide range of duties that extend beyond standard definitions of home support, of particular relevance to smaller communities with limited access to other health and social services. The primary facilitator of CHW recruitment and retention was the opportunity to build positive relationships with clients. Wages were the primary barrier to CHW recruitment and retention, in particular the wage disparity between community- and facility-based workers. Other barriers included the costs associated with paying for one’s own mobile phone and using one’s own vehicle on the job, CHWs’ unpredictable schedules, and feeling isolated from other members of the health care team.

description: Emblematic conducting performance involves the practice of significant non-verbal gestures to convey a musical interpretation that supports a homogeneous relationship of gesture and sound. The complex theories of audiovisual perception and the dynamic relationship that exists between a conductor and an ensemble is a fascinating topic worthy of exploration. New methods and approaches to teaching and evaluating gesture are beneficial and further the technical development of undergraduate conductors. Non-traditional learning sessions designed to improve goal-directed actions and the perceptual understanding of emblems involved the use of motion capture technology and body mind flow exercises. This investigation compiled data acquired from participant interviews and self-evaluations. Feedback collected from a chamber ensemble and an expert panel helped to validate the usefulness of the pedagogies. Gesture reviews that utilized point-light videos and corresponding sound moments and emblem identification tests helped strengthen each conductor’s self-awareness and sonic-object familiarity in an unbiased manner. Emblem practices addressed in training helped the conductors to improve the expressivity and specificity of their gestures. Interaction with motion capture technology, hands-on performance of march-style excerpts and body mind flow exercises raised the contextual focus the conductors applied to their movement executions.

description: We adopt a field theoretical approach to study the structure and thermodynamics of a homogeneous Maier-Saupe nematogenic fluid interacting with anisotropic Yukawa potential. In the mean field approximation we retrieve the standard Maier-Saupe theory for liquid crystals. In this theory the density is expressed via the second order Legendre polynomial of molecule orientations. In the Gaussian approximation we obtain analytical expressions for the correlation functions, the elasticity constant, the free energy, the pressure, and the chemical potential. We also use Ward symmetry identities to set a simple condition for the correlation functions. Subsequently we find corrections due to fluctuations and show that density now contains Legendre polynomials of higher orders.

Frequency Diversity in Mode-Division Multiplexing Systems

description: In the regime of strong mode coupling, the modal gains and losses and the modal group delays of a multimode fiber are known to have well-defined statistical properties. In mode-division multiplexing, mode-dependent gains and losses are known to cause fluctuations in the channel capacity, so that the capacity at finite outage probability can be substantially lower than the average capacity. Mode-dependent gains and losses, when frequency-dependent, have a coherence bandwidth that is inversely proportional to the modal group delay spread. When mode-division-multiplexed signals occupy a bandwidth far larger than the coherence bandwidth, the mode-dependent gains and losses are averaged over frequency, causing the outage capacity to approach the average capacity. The difference between the average and outage capacities is found to be inversely proportional to the square-root of a diversity order that is given approximately by the ratio of the signal bandwidth to the coherence bandwidth.

description: In this paper, we propose a randomized Bayesian optimal phase II (RBOP2) design with a binary endpoint (e.g., response rate). A beta-binomial distribution is used to model the binary endpoint for a two-arm phase II trial. Posterior probabilities of the endpoint of interest are evaluated at each interim look and used in the decision to stop the trial due to futility. Compared with other Bayesian designs, the proposed RBOP2 design has the following merits: (i) strongly controls the type I error rate at a pre-defined level; (ii) optimizes the stopping boundaries, thus maximizing the power to detect treatment effects and minimizing the expected sample size for futile treatment; (iii) does not limit the number of interim looks, thus enabling frequent trial monitoring; and (iv) allows the stopping boundaries to be pre-defined in the protocol and is easy to implement. We conduct simulation studies to compare the proposed design with a group sequential design and other Bayesian randomized designs and evaluate its operating characteristics under different scenarios.
Funding a Smoking Cessation Program for Patients with Crohn's Disease: An Economic Evaluation

description: Crohn’s disease (CD) is increasing in incidence and prevalence in Canada. It is diagnosed relatively early in life, and is a life-long burden to those who have it. Numerous risk factors have been associated with the development and exacerbation of CD, but one of the most prevalent modifiable risk factors is smoking; people who smoke have a higher likelihood of developing CD than those who do not smoke. Those who smoke after CD development experience more deleterious events during their disease course compared to those who do not smoke. The health care system does not regularly supply smoking cessation programs for these individuals, nor fund them, even though it has been shown that CD patients have a higher rate of smoking cessation than the general population. Therefore, the goal of this thesis is to assess the cost-effectiveness of funding smoking cessation programs for incidence cases of CD.

description: Approximately 16% of ulcerative colitis (UC) patients will have a colectomy within 10 years of their diagnosis of UC. Due to the high morbidity and mortality associated with colectomy procedures, clinicians and patients strive to avoid surgery. The decline of colectomy rates over the last 6 decades has been mainly attributed to advances in medical management of UC. Clostridium difficile infection and colorectal neoplasia have also been associated with driving the risk of colectomy. This dissertation focuses on describing the effect of C. difficile and colorectal neoplasia on the risk of colectomy for UC patients. Chapters 2 and 3 establish the cumulative risk of acquiring C. difficile infection after the diagnosis of UC and demonstrated that C. difficile infections increase the short- and long-term risk of colectomy. Further, both Chapters 2 and 3 demonstrate that C. difficile infections increased the risk of postoperative complications following colectomy for UC. Chapter 4 demonstrate that the incidence of colectomy for colorectal dysplasia and cancer has remained stable over time, and showed that the observed decrease in colectomy rates is most likely due to a decrease in colectomies from medically refractory disease. Finally, Chapter 5 determined the cost-effectiveness of different surveillance colonoscopy intervals for colorectal dysplasia among a subgroup of inflammatory bowel disease (IBD) patients with a higher risk of developing colorectal dysplasia and cancer; i.e., patients with IBD and primary sclerosing cholangitis (PSC).

We are told that we didn’t become privy to the inner workings and implementation of these laws. The reality is that there were waves of American scientists and journalists that were invited to survey, and sometimes even participate, in the daily implementation of National Socialism’s eugenic state. These scientists, doctors, and journalists then reported back, writing papers and articles that gave cover and a veil of scientific legitimacy to Nazism’s racial hygiene laws.

description: In meta-analysis practice, researchers frequently face studies that report the same outcome differently, such as a continuous variable (e.g., scores for rating depression) or a binary variable (e.g., counts of patients with depression dichotomized by certain latent and unreported depression scores). For combining these two types of studies in the same analysis, a simple conversion method has been widely used to handle standardized mean differences (SMDs) and odds ratios (ORs). This conventional method uses a linear function connecting the SMD and log OR; it assumes logistic distributions for (latent) continuous measures. However, the normality assumption is more commonly used for continuous measures, and the conventional method may be inaccurate when effect sizes are large or cutoff values for dichotomizing binary events are extreme (leading to rare events). This article proposes a Bayesian hierarchical model to synthesize SMDs and ORs without using the conventional conversion method. This model assumes exact likelihoods for continuous and binary outcome measures, which account for full uncertainties in the synthesized results. We performed simulation studies to compare the performance of the conventional and Bayesian methods in various settings. The Bayesian method generally produced less biased results with smaller mean squared errors and higher coverage probabilities than the conventional method in most cases. Nevertheless, this superior performance depended on the normality assumption for continuous measures; the Bayesian method could lead to nonignorable biases for non-normal data. In addition, we used two case studies to illustrate the proposed Bayesian method in real-world settings.

description: Abstract This thesis examines National Energy Board (NEB) decisions, legislation and policy documents regarding access to oil and natural gas export pipelines. The NEB approach to regulation of access to pipelines has changed over time as oil and gas markets have changed. Originally, oil pipelines were entirely common carriers. In the last fifteen years, the NEB has approved new oil pipelines in which the majority of capacity is subject to firm contracts, provided that certain conditions are met. Currently, capacity in oil export pipelines is tight. The thesis recommends that the NEB codify its current approach to access to oil export pipelines, with some minor improvements, to provide certainty and transparency. Natural gas pipelines are contract carriers. As there is currently adequate capacity in natural gas export pipelines, no changes to the NEB approach to access to natural gas pipelines are recommended at this time.

description: We investigate the effects of disorder on the propagation of one-dimensional polariton condensates in semiconductor microcavities. We observe a strong suppression of the backscattering produced by the imperfections of the structure when increasing the condensate density. This suppression occurs in the supersonic regime and is simultaneous to the onset of parametric instabilities which enable the "hopping" of the condensate through the disorder. Our results evidence a new mechanism for the frictionless flow of polaritons at high speeds.

description: Graph Convolutional Networks (GCN) which typically follows a neural message passing framework to model dependencies among skeletal joints has achieved high success in skeleton-based human motion prediction task. Nevertheless, how to construct a graph from a skeleton sequence and how to perform message passing on the graph are still open problems, which severely affect the performance of GCN. To solve both problems, this paper presents a Dynamic Dense Graph Convolutional Network (DD-GCN), which constructs a dense graph and implements an integrated dynamic message passing. More specifically, we construct a dense graph with 4D adjacency modeling as a comprehensive representation of motion sequence at different levels of abstraction. Based on the dense graph, we propose a dynamic message passing framework that learns dynamically from data to generate distinctive messages reflecting sample-specific relevance among nodes in the graph. Extensive experiments on benchmark Human 3.6M and CMU Mocap datasets verify the effectiveness of our DD-GCN which obviously outperforms state-of-the-art GCN-based methods, especially when using long-term and our proposed extremely long-term protocol.

description: В данной работе рассмотрено детское краеведческое движение 1960—1990-х гг. на примере деятельности клуба юных краеведов, основанного в 1964 году учителем истории З.С.Сорокиной в школе № 7 г. Боровичи Новгородской области. Работа кружка рассматривается с двух сторон: 1) краеведение как одна из форм культуры и досуга советской молодёжи; 2) участие школьников в археологических экспедициях и их вклад в сохранение памятников истории и культуры. Ученики занимались исследованием родного края: изучали топонимику, этнографию, ботанику, археологию, учились картографированию, ориентированию на местности, жизни в полевых условиях. Особое внимание уделялось изучению археологических памятников. Это направление работы поддерживалось боровичскими краеведами, археологами Новгородского пединститута, Новгородского музея, Института археологии АН СССР, областным отделением Всероссийского общества охраны памятников истории и культуры, а также государственным органом по охране памятников.
Modelling urban development trends and outdoor residential water demand in the Okanagan Basin, British Columbia

description: The Okanagan Basin, the most arid watershed in Canada per capita, has been undergoing rapid population growth in the past 30 years. The results of this research show the varying residential water demand in the major communities in the Okanagan Basin. The outdoor water use was determined on a lot size basis for 2006 and projections were made to the year 2026 using a projected population increase and three urban development scenarios. The outdoor residential water demand varied from 30% to 60% of the annual domestic water demand depending on lot size. Two extreme urban growth cases: urban sprawl and densification, and an in-between scenario were developed using GIS for four case study communities: Vernon, Kelowna, Penticton and Osoyoos, which represent the diversity in climate and population trends in the Basin. The results showed that currently 47% of the domestic water is used for outdoor watering for the case studies. The business as usual growth scenario (urban sprawl), includes climate change and results in 7.3 Mm3 of additional water needed for outdoor residential water demand, a 55% increase from existing conditions. However, with densification, 5.7 Mm3 of outdoor residential water savings can be made. Additional water savings can be made if the existing outdoor residential water demand is reduced through more aggressive conservation practices such as effective marketing, reduced grassed area through xeriscape and mandatory watering restrictions. Using current growth projection to 2026 it is possible to significantly reduce outdoor residential water demand by more than 50% from existing conditions if densification and aggressive conservation practices are put in place. The methods and results of this research have been incorporated into the Okanagan Basin Water Supply and Demand Project, which is in the final phases of completion.

description: The idea of unifying quarks and leptons in a gauge symmetry is very appealing. However, such an unification gives rise to leptoquark type gauge bosons for which current collider limits push their masses well beyond the TeV scale. We present a model in the framework of extra dimensions which breaks such quark-lepton unification symmetry via compactification at the TeV scale. These color triplet leptoquark gauge bosons, as well as the new quarks present in the model, can be produced at the LHC with distinctive final state signatures. These final state signals include high p_T multi-jets and multi-leptons with missing energy, monojets with missing energy, as well as the heavy charged particles passing through the detectors, which we also discuss briefly. The model also has a neutral Standard Model singlet heavy lepton which is stable, and can be a possible candidate for the dark matter.

International Trade, the Environment and Natural Resources

description: The linkage between trade and environment has been debated for several decades. The first chapter of my thesis examines how differences in environmental regulations across countries may affect trade patterns and pollution emissions when pollution is created by consumption. I develop a model of trade with new and used automobile choice and demonstrate that trade necessarily lowers emissions from the dirty good exporter and trade has a channel to lower emissions from the dirty good importer. Empirical results show that Mexico imported 6 million used cars from 2005 to 2010, which raises car emissions of major pollutants from Mexico by over 20%: emission intensity differences across countries lowers car emissions by less than 1% and is denominated by emission rise through a larger and older car fleet. Clean technologies curb global emissions but require as inputs rare earth elements (REEs), which pollute the local environment. China, the major producer of REEs, has been challenged at the WTO for its export restriction on REEs and has proposed to switch to a domestic environmental policy. In the second chapter, my coauthor and I examine these policies in a model with a vertical market structure in which governments trade of concerns for the local and global environments with the rent-shifting benefits of strategic policies. We find that replacing the trade policy on REEs with a domestic environmental policy will hurt global clean tech industries and other countries do not necessarily benefit from this change. In the standard theory of international trade, each of the production factors is inexhaustible. To understand how the exhaustibility of non-renewable resources works, in the third chapter, my coauthor and I analyze dynamically consistent extraction equilibria of non-renewable resource extraction, where firms move sequentially within each period and where both the leader and follower have market power. We show that the leader is able to manipulate extraction patterns by exploiting resource constraints. Unlike static Stackelberg games, the follower does not necessarily have a second mover disadvantage.
Generalized Brauer dimension of semi-global fields

description: Let $F$ be a one variable function field over a complete discretely valued field with residue field $k$. Let $n$ be a positive integer, coprime to the characteristic of $k$. Given a finite subgroup $B$ in the $n$-torsion part of the Brauer group ${}_{n}br(F)$, we define the index of $B$ to be the minimum of the degrees of field extensions which split all elements in $B$. In this thesis, we improve an upper bound for the index of $B$, given by Parimala-Suresh, in terms of arithmetic invariants of $k$ and $k(t)$. As a simple application of our result, given a quadratic form $q/F$, where $F$ is a function field in one variable over an $m$-local field, we provide an upper-bound to the minimum of degrees of field extensions $L/F$ so that the Witt index of $q otimes L$ becomes the largest possible.
