The relevance of stewardship in contemporary Anglican theology to sustainability planning
Creators: name: Dampier, Paige Allison Bain
Publisher: name: University of British Columbia
Year: 2009

description: The basis for this research project is my belief that the planet is in ecological crisis. This crisis has been brought about by an unhealthy vision for humanity as dominators of the ecosphere. The vision manifests itself in a belief that further scientific and technological advances will result in solutions to the 'environmental problem'. As a response to this position, this research project examines stewardship, from an Anglican theological understanding, as an alternative to the current paradigm. A stewardship response to the ecological crisis does not look to technology for solutions, but rather bases its strategies in behavioural change at the level of the individual and then the individual in community. I used theological and archival sources as well as accounts from volunteers and staff from two local Anglican dioceses and two parishes to develop a concept of stewardship that might be appropriate for use by planners. I recognized that the stewardship model developed within the thesis is but one of any number of possible alternative paradigms that could and should be pursued. What emerges is an understanding that stewardship is a valid and powerful model for behavioural change, especially when sustainability planning concepts are incorporated into it for use in long-term planning for community vision. When this partnership between disciplines occurs, behavioural change becomes a real possibility and a cause for hope. Transformative theory stands as a rallying point for stewardship alongside many other paradigms to work together to change the balance of power. The role of the planner emerges as one of mediator and facilitator within a context of multiple knowledges working towards a common goal.

description: This study investigates distribution of natural and technogenic radionuclides in rock samples in the eastern part of Kakheti region. The radioactivity of rocks in this region has not been investigated. 20 samples of rocks of various types – igneous, sedimentary and metamorphic were investigated with the gamma-spectroscopic method applied. Up to 21 naturally occurring radionuclides and 1 technogenic radionuclide have been identified in samples. Average activity concentration of Th-232 family radionuclides varied from 0.61 to 98.6 Bq/kg, U-238 family - from 9.1 to 77.0 Bq/kg, U-235 family - from 0.10 to 3.5 Bq/kg. The highest activity concentration was observed for K-40 (maximal value of 1475 Bq/kg). Activity of technogenic radionuclide Cs-137 varied from 0.10 to 1.2 Bq/kg. There are some marked features in radionuclides distribution depending, in particular, on rock type, tectonic zone. Some radionuclide activity ratios have been considered, in particular, U238/U-235, U-238/Th-232, Ra-226/U-238 and Pb-210/Ra 226. These ratios allow to estimate condition of system (closed or opened) and to receive a certain notion about character of relevant geochemical processes. Comparison was carried out with existing data in the literature.

description: In this paper, we study 2d Floquet conformal field theory, where the external periodic driving is described by iterated logistic or tent maps. These maps are known to be typical examples of dynamical systems exhibiting the order-chaos transition, and we show that, as a result of such driving, the entanglement entropy scaling develops fractal features when the corresponding dynamical system approaches the chaotic regime. For the driving set by the logistic map, fractal contribution to the scaling dominates, making entanglement entropy highly oscillating function of the subsystem size.

description: This review discusses the current status of supermassive black hole research, as seen from a purely observational standpoint. Since the early '90s, rapid technological advances, most notably the launch of the Hubble Space Telescope, the commissioning of the VLBA and improvements in near-infrared speckle imaging techniques, have not only given us incontrovertible proof of the existence of supermassive black holes, but have unveiled fundamental connections between the mass of the central singularity and the global properties of the host galaxy. It is thanks to these observations that we are now, for the first time, in a position to understand the origin, evolution and cosmic relevance of these fascinating objects.

description: This article presents the results of studies that examined the general antiradical status (TAA) of the body as a potential biomarker of the effects of radiation exposure. Thirty patients (60-70 years old) with squamous cell carcinoma of the larynx participated in the study. Every patient underwent fractional radiation therapy. Irradiation was performed on a linear accelerator in 2 gray/fraction mode, with a total dose of 70 gray given by a radical program. The examination of blood TAA was performed before the treatment (I) in the middle of treatment where the patient had received half of the total acceptable treatment dose (II) and after the radiation (III). In our study it was found that the TAA of blood increases linearly within the error, which indicates the activation of the body's antioxidant defense systems with the aim to neutralize the radicals generated by ionizing radiation. The results of our investigation support the fact that the non-enzymatic antiradical system plays an important role in the prevention of radiation damage during ionizing radiation exposure.

The effects of race, caucasian versus Chinese, on immittance audiometry norms
Creators: name: Davies, Dreena
Publisher: name: University of British Columbia
Year: 2009

description: This study examined racial differences between a group of normal hearing Caucasian and Chinese young adults on 5 tympanometric parameters. The goal of this study was to determine if the Chinese young adults had different low and multifrequency tympanometry results than the Caucasian young adults. There were a total of 40 subjects (and 80 ears) between the ages of 18 and 34 years, with 20 subjects (and 40 ears) per race group. Tympanometric data was gathered on a clinical immittance machine, the Virtual 310 equipped with an extended high frequency option. Two parameters—static admittance (SA) and tympanometric width (TW)—were measured at a standard low probe tone frequency of 226 Hz. The remaining 3 parameters—resonant frequency (RF), the frequency corresponding to an admittance phase angle of 45°, and SA up to 1200 Hz—could only be measured by multifrequency, multicomponent tympanometry. Findings indicated that all parameters except one (TW) showed a significant race effect. The parameter of SA up to 1200 Hz showed a significant race effect until 800 Hz. A significant measurement estimate effect (for negative vs. positive compensation and sweep pressure vs. sweep frequency) was found in all parameters except RF. Results from this study show that there is a significant race difference between Caucasian and Chinese adults on 4 tympanometric measures. The clinical implications of these findings are that audiologists should consider using race-based normative data when assessing patients with immittance audiometry. These findings suggest that further research into racial differences between other races should be initiated. Future research may also benefit from addressing racial differences in different age populations as well as determining the anatomic reasons for these differences.

description: In the software rich environment of 6G, systems will be surrounded by edge devices that sup- port distributed software systems which are critical to operations. Such systems may also be subject to frequent updates or uploads of individual software components. Trust in such systems will therefore depend on our ability to rapidly ensure that such software is not vulnerable to cyberattacks or malicious compromises. Thus this paper presents a novel System-Wide Vulnerability Assessment (SWVA) framework based on Machine Learning, that can be frequently activated to assess the vulnerability of interconnected software components over edge systems. The performance of the SWVA framework is illustrated by assessing the vulnerability of 13 versions of a real- world 11 component software system, and comparing the ARNN results against the well-known ML models MLP, KNN, and Lasso. The results show the superior performance of SWVA, offering over 85% median accuracy and good scalability as the number of connected software components increases.
Signals for CP Violation in Split Supersymmetry

description: Split supersymmetry is characterized by relatively light chargino and neutralino sector and very heavy sfermion sector. We study the consequence of CP violation in this scenario by evaluating two-loop contributions to electric dipole moments of fermions from Higgs-photon as well as $W$-$W$ diagrams. These contributions add coherently and produce electron and neutron electric dipole moments close to present bounds. We then explore Higgs production at a photon-photon collider, and consider the feasibility of measuring CP violating $hγγ$ coupling induced by chargino loops. Methods of enhancing the sensitivity are discussed. For lower chargino masses and lower Higgs boson masses, the effect of the CP violation can be observed with 90% confidence level significance.

Subjects: subject: Optics (physics.optics)

description: Spatial filtering is a commonly deployed technique to improve the quality of laser beams by optically filtering the noise. In the "textbook" example, the noise is usually assumed to be high frequency and the laser beam, Gaussian. In this case, the filtering is achieved by a simple pin-hole placed at the common focal plane of two lenses. Here, we explain how to generalize the concept of spatial filtering to arbitrary beam profiles: spatial filtering of structured light. We show how to construct the spatial filters using a range of structured light examples, and highlight under what conditions spatial filtering works. In the process, we address some misconceptions in the community as to how and when spatial filters can be applied, extend the concept of spatial filtering to arbitrary beam types and provide a theoretical and experimental framework for further study at both the undergraduate and graduate level.
Junction conditions of cosmological perturbations

description: The behavior of perturbations is studied in cosmological models which consist of two different homogeneous regions connected in a spherical shell boundary. The junction conditions for the metric perturbations and the displacements of the shell boundary are analyzed and the surface densities of the perturbed energy and momentum in the shell are derived, using Mukohyama's gauge-invariant formalism and the Israel discontinuity condition. In both homogeneous regions the perturbations of scalar, vector and tensor types are expanded using the 3-dimensional harmonic functions, but the model coupling among them is caused in the shell by the inhomogeneity. By treating the perturbations with odd and even parities separately, it is found, however, that we can have consistent displacements and surface densities for given metric parturbations

General Principles of the Organisation of the Mechanisms of Biological Adaptation

name: Lapan, O.V.
Publisher: name: Radiobiology and Radiation Safety
Year: 2021

description: The existence of a hierarchy of mechanisms of their functioning and a hierarchy of mechanisms of the response to stressors is substantiated. That is based on the fact of the existence of a hierarchical organization of biological systems. It was shown that the adaptive response had been based on the hormesis action of the factor, and the study of the mechanism of adaptive action can be reduced to the study of the mechanism of hormesis effects caused by hypercompensatory processes in objects exposed to a certain stress factor. There is constitutive and inducible/stimulated phenotypic hyperadaptation (PHA). It occurs at the certain stage of positive readjustment of the initial state of the biological object in response to the action of above-threshold levels of factors of any nature. PHA is a process and it is the result of the functioning of constitutive or inducible/stimulated mechanisms of recovery. The whole hierarchy of recovery mechanisms, of which there are as many as there are recovery mechanisms (levels), can provide PHA at a particular level of the organization. PHA has a transitive and transient nature. There is a possibility of consolidating the state of hyperadaptation, when post-factor (post-stress) conditions contribute to its manifestation. At the base of PHA there are the processes of modification (in particular, degradation), the result of which is the emergence of appropriate signals that determine the final implementation of the mechanisms of hyperadaptation.

Social capital, trust foundation and risk construction as social determinants of blood donation
Creators: name: Fiddler, Jay A.
Publisher: name: University of British Columbia
Year: 2009

description: Understanding blood donor motivation has been the focus of much research in the past decade. To date the majority of this research has focused on individual factors related to altruism and "altruistic identity". Although important, such knowledge has been unable to produce an increase in blood donors. One aspect of blood donation that has been under-explored is the role of social determinants in blood donation. Current data demonstrates the demographic differences in blood donor rates by race, ethnicity, gender, age, geographic locale, community and income. Such findings suggest that it is important to understand how social factors influence donation. Thus, this paper is premised on the idea that blood donation is best understood through an examination of the social context in which decision to donate blood occur. In order to conceptualize the social context of blood donation, I utilized the theoretical perspectives of social capital, trust foundation and risk analysis. Such perspectives provided an important framework with which to understand both donation and non-donation. Current CBS data indicates that community-based donation programs are more effective at stimulating continued donation than are individual-based programs. As well, academic literature has demonstrated that issues of trust and perceptions of risk are mediated when donation occurs in a community-based setting. Such findings challenge the notion of individual altruism as the main explanatory factor in blood donation. Instead, demonstrating how social factors including community and social network relationships provide motivation to donate that altruistic appeals do not. Therefore, decisions to donate cannot be removed from the social context in which such decisions occur.

Insights from Poverty Maps for Development and Food Relief Program Targeting: An Application to Malawi

description: Poverty mapping applies models of household welfare developed from detailed household consumption and expenditure surveys to the extensive but less detailed data from national censuses. A poverty map for Malawi, developed by drawing upon information from the 1997–98 Malawi Integrated Household Survey with the 1998 Malawi Population and Housing Census, provides aggregate estimates of household welfare and poverty at a highly disaggregated level—down to the level of local government wards. Given the close association between welfare and food security in most Malawi households, such a detailed poverty map can be of considerable value to development and relief organizations, as they plan and target activities to improve the ability of poor households to cope with food scarcity. This paper assesses the value of the Malawi poverty map with reference to two activities of the World Food Programme (WFP) in Malawi: the Food for Assets and Development (FFASD) public works program and the Vulnerability Analysis and Mapping (VAM) food insecurity information generation system. First, the poverty targeting efficiency of the FFASD program is evaluated using the poverty map to determine whether the FFASD projects are preferentially located in areas where disproportionate numbers of the poor are found. This is done in part by comparing the poverty targeting efficiency of the WFP program to that of the Malawi Social Action Fund Public Works Programme projects. Second, WFP employs the VAM methodology to determine how and where to employ its resources from year to year. The potential value of the poverty map as a component of the VAM process in Malawi is then considered. The results indicate that the poverty map is an effective and objective way to geographically target projects and programs on a poverty basis in Malawi. In assessing household vulnerability to food insecurity, the poverty map serves as a useful proxy indicator of spatial variability in the ability of the population to cope with food scarcity. Poverty maps, in those countries were they are available, should be a privileged data source for undertaking any national vulnerability analyses. However, the poverty map needs to be used with complementary data to better understand the risks households face that might result in food scarcity and the actual mechanisms households use to cope with such stresses.
Understanding chemical reactions in a quantum degenerate gas of polar molecules via complex formation

description: A recent experiment reported for the first time the preparation of a Fermi degenerate gas of polar molecules and observed a suppression of their chemical reaction rate compared to the one expected from a purely classical treatment. While it was hypothesized that the suppression in the ultracold regime had its roots in the Fermi statistics of the molecules, this argument is inconsistent with the fact that the Fermi pressure should set a lower bound for the chemical reaction rate. Therefore it can not be explained from standard two-body $p$-wave inelastic collisions. Here we develop a simple model of chemical reactions that occur via the formation and decay of molecular complexes. We indeed find that pure two-body molecule losses are unable to explain the observed suppression. Instead we extend our description beyond two-body physics by including effective complex-molecule interactions possible emerging from many-body and effective medium effects at finite densities and in the presence of trapping light. %Under this framework we observe that additional complex-molecule collisions, which manifest as a net three-body molecular interaction could give rise to the additional suppression. Although our effective model is able to quantitatively reproduce recent experimental observations, a detailed understanding of the actual physical mechanism responsible for these higher-order interaction processes is still pending.

description: Let K be a p-adic field, R the valuation ring of K, P the maximal ideal of R and q the cardinality of the residue field R/P. Let f be a polynomial over R in n>1 variables and let χbe a character of R^{\times}. Let M_i(u) be the number of solutions of f=u in (R/P^i)^n for i \in \mathbb{Z}_{\geq 0} and u \in R/P^i. These numbers are related with Igusa's p-adic zeta function Z_{f,χ}(s) of f. We explain the connection between the M_i(u) and the smallest real part of a pole of Z_{f,χ}(s). We also prove that M_i(u) is divisible by q^{\ulcorner(n/2)(i-1)\urcorner}, where the corners indicate that we have to round up. This will imply our main result: Z_{f,χ}(s) has no poles with real part less than -n/2. We will also consider arbitrary K-analytic functions f.

We solve the dynamical mean field theory equations with the non crossing approximation and we use the coherent potential approximation to handle disorder. The excitation spectrum is given for various correlation strength $U$ and disorder. Two successive metal insulator transitions are observed at integer filling values as $U$ is increased. An important selective transfer of spectral weight arises upon doping. The strong influence of the temperature on the low energy dynamics is studied in details.

We reveal strong anomalies between 140 K and 200 K in the frequency of magnon and E(LO1), E(TO1) and A1(LO1) phonon modes. These anomalies are related to a surface expansion and are enhanced for nanoparticle sizes approaching the spin cycloidal length. These observations point out the strong interplay between the surface, the lattice, and the magnetism for sizes of BiFeO3 nanoparticles close to the cycloid periodicity.

It was shown, that possible use of gamma irradiation together with Ni(II),Cr(III), Cu(II),Pb(II), Cd(II),Co(II) and Zn(II) ions does not change nature of interaction of these metal ions on Spirulina platensis. In the case combined effects of ionizing radiation and Mg(II) ions for Spirulina platensis exhibit synergetic effects for all components of Spirulina platensis as a stimulatory agent to raise the contents of it. This trend is seen to continue for all constituents of Spirulina platensis when these metal ions were added in vitro after one year irradiation and recultivation. Chromium (VI) does not contribute to a decrease in absorption intensity unlike Cr(III) and Cu(II). Influence of these metal ions on the constituent (Chl a, Phycocyanin, soret band of Chl a) of cyanobacterium Spirulina platensis differs from its effectiveness.

description: We explore how globalization, broadly conceived to include international human-rights norms, humanitarianism, and alternative trade, might influence peaceful and food-secure outlooks and outcomes. The paper draws on our previous work on conflict as a cause and effect of hunger and also looks at agricultural exports as war commodities. We review studies on the relationships between (1) conflict and food insecurity, (2) conflict and globalization, and (3) globalization and food insecurity. Next, we analyze country-level, historical contexts where export crops, such as coffee and cotton, have been implicated in triggering and perpetuating conflict. These cases suggest that it is not export cropping per se, but production and trade structures and food and financial policy contexts that determine peaceful or belligerent outcomes. Export cropping appears to contribute to conflict when fluctuating prices destabilize household and national incomes and when revenues fund hostilities. Also, in these scenarios, governments have not taken steps to progressively realize the right to adequate food or to reduce hunger and poverty. We conclude by exploring implications for agricultural development, trade, and human-rights policies.

description: In all neighboring countries of Georgia, programs for the construction and operation of nuclear power plants of various capacities are being actively developed, which does not exclude the problems of radionuclide emissions and migration during technogenic accidents. A special place in this regard is occupied by the study and forecasting of possible food contamination mechanisms by taking into account the specifics of the food ration of the local population for each region. The present paper discusses the peculiarities of the accumulation of radionuclides by culinary herbs typical for Georgia. They are one of the main ingredients for Georgian national cuisine. Based on the experimental data obtained, calculations have been made on the possible risks to the health of the population in the event of extreme contamination of territories with anthropogenic radionuclides. By comparing the accumulation coefficients of radionuclides (radiocesium) in the tissues of culinary herbs with the level of the average consumption of these ingredients, additional parameters of dose load at the level of various organs of the human body have been determined. Based on the use of software modeling methods, the possible risks of radiobiological effects dangerous to health, on the example of radiation cancer development, during radionuclide contamination of culinary herbs in Georgia, through their long-term consumption for food, were identified.

description: For effective decision-making, policymakers and program managers often need detailed information about the welfare of the population, including knowledge about which specific areas are most affected by poverty and undernutrition. Household sample surveys are an important source of information, yet because the typical sample size is only a few thousand observations, the information is only useful for inferences at high levels of aggregation, such as the nation or large regional units. In contrast, data sources with wider coverage, such as national censuses, rarely capture detailed information on welfare levels. Recently small-area estimation techniques have been applied to the study of poverty to produce estimates of poverty, or poverty maps, for small geographic units. This paper uses household survey and unit record census data from Tanzania to explore the possibility of applying small-area estimation methods to the study of children’s nutritional status as measured by anthropometry. Overall, undernutrition models have had lower explanatory power than poverty models, which has important implications for the precision of the small-area estimates. The analysis finds that applying small-area estimation techniques to anthropometric data is feasible, although the relatively low explanatory power of the regressions does limit both the degree of disaggregation possible and the power to detect significant differences in undernutrition prevalence between districts and subdistricts. In the case of Tanzania, the nutrition mapping approach reveals considerable heterogeneity in nutritional status within regions and within districts. The most striking finding is the much lower levels of undernutrition in areas classified as urban, including relatively small district centers.

description: Preferential measures for developing countries implemented within the General Agreement on Tariffs and Trade failed to achieve their purported goal of facilitating economic development; this failure was due to their weak theoretical underpinnings and poor policy design. Not only were the demands developing countries made for discriminatory preferences largely ineffectual, their demands for preferential treatment, together with their forgoing full participation in the multilateral trading system, fundamentally reduced the obligation of developed countries to consider the interests of developing countries in future negotiation rounds. Thus the winning of preferences was rendered a pyrrhic victory for developing countries.

description: In supersymmetric models where the gravitino is the lightest superparticle, the next-to-lightest superparticle (NLSP) is long-lived, and hence could be collected and studied in detail. We study the prospects of direct detection of lepton flavour violation in charged slepton NLSP decays. Mixing angles in the slepton sector as small as ~ 3\times 10^{-2} (9\times 10^{-3}) could be probed at the 90% confidence level if 3\times 10^3 (3\times 10^4) sleptons could be collected.

description: Uncertainty relations for mixed quantum states (precisely, purity-bounded position-momentum relations, developed by Bastiaans and then by Man'ko and Dodonov) are studied in general multi-dimensional case. An expression for family of mixed states at the lower bound of uncertainty relation is obtained. It is shown, that in case of entropy-bounded uncertainty relations, lower-bound state is thermal, and a transition from one-dimensional problem to multi-dimensional one is trivial. Results of numerical calculation of the relation lower bound for different types of generalized purity are presented. Analytical expressions for general purity-bounded relations for highly mixed states are obtained.

description: Measuring local temperatures of open systems out of equilibrium is emerging as a novel approach to study the local thermodynamic properties of nanosystems. An operational protocol has been proposed to determine the local temperature by coupling a probe to the system and then minimizing the perturbation to a certain local observable of the probed system. In this paper, we first show that such a local temperature is unique for a single quantum impurity and the given local observable. We then extend this protocol to open systems consisting of multiple quantum impurities by proposing a local minimal perturbation condition (LMPC). The influence of quantum resonances on the local temperature is elucidated by both analytic and numerical results. In particular, we demonstrate that quantum resonances may give rise to strong oscillations of the local temperature along a multiimpurity chain under a thermal bias.

description: We apply strategy of variational measurement to simplest variant of dissipative coupling (test mass displacement change transitivity of a single mirror) and compare it with simplest dispersive coupling (a single mirror as a test mass, which position changes the phase of reflected wave). We compare a ponderomotive squeezing in this two kinds of coupling. Also we analyze simplest variant of combined coupling, in which both dissipative and dispersive couplings are used, and show that it creates stable optical rigidity even in case of single pump. We demonstrate that variational measurement can be applied for combined coupling.

description: Analyser-Based Phase-Contrast imaging (ABPCI) is a phase-contrast imaging method that produces high contrast images of weakly absorbing materials. However, it is only sensitive to phase variations lying in the diffraction plane of the analyser crystal (i.e in one dimension; 1-D), as it is highly sensitive to phase variations lying in the diffraction plane of the analyser crystal. In order to accurately account for and measure phase effects produced by the wavefield-sample interaction, ABPCI and other 1-D phase sensitive methods must achieve 2-D phase sensitivity. We applied an inclined geometry method to a Laue geometry setup for X-ray ABPCI through rotation of the detector and object about the optical axis. This allowed this traditionally 1-D phase sensitive phase contrast method to possess 2-D phase sensitivity. We acquired tomographic datasets over 360 degrees of a multi-material phantom with the detector and sample tilted by 8 degrees. The real and imaginary parts of the refractive index were reconstructed for the phantom.

description: We study the finite-size corrections of the dimer model on $\infty \times N$ square lattice with two different boundary conditions: free and periodic. We find that the finite-size corrections in a crucial way depend on the parity of $N$; we also show that such unusual finite-size behavior can be fully explained in the framework of the $c=-2$ logarithmic conformal field theory.
