A survey of wildlife rehabilitation goals, impediments, issues, and success in British Columbia, Canada
Creators: name: Dubois, Sara
Publisher: name: University of British Columbia
Year: 2009

description: Wildlife rehabilitators have various levels of training, most relying on their personal experience, while many also work to some degree with veterinarians. Rehabilitators also operate within a regulatory framework created by government agencies. Based on their own experience and training, these groups may have different perceptions of the value of wildlife, of rehabilitation goals, and of its impediments. Additionally, there is great scope for disagreement on numerous practice issues such as methods of care and euthanasia. Disclosure of these value positions and issues is important in resolving how stakeholders can work together more effectively to promote the welfare of individual wildlife. Also, to assess the accomplishments and areas of improvement for rehabilitation, it is important to identify what constitutes rehabilitation success and determine how to effectively evaluate success. Therefore, this study aims to describe rehabilitation goals, impediments, and issues, and discuss rehabilitation success and its measures, among stakeholders. This is achieved through a comprehensive survey, using interviews, questionnaires, and analysis of summary records. Participants in all three groups saw the primary goals of rehabilitation as humane treatment and public education; however, rehabilitators recognized a wider range of goals than others. This may help to explain why, despite members of all groups identifying multiple components of rehabilitation success, more rehabilitators had a broader view of success than others. Rehabilitators further differed from other stakeholders when discussing rehabilitation impediments; most participants cited money, however, over half the rehabilitators also felt that a lack of non-monetary assistance or acknowledgement by government were important impediments. Major disagreements exist on the care of nonnative species and the use of non-releasable animals for education. Although consensus was not achieved in all areas, consistent data recording and analysis, promotion of existing care and euthanasia guidelines, and increased enforcement and care assessments by a team of stakeholders, may serve to better inform practices and decision-making within the rehabilitation community. Finally, rehabilitation success of treating animals can be assessed by comparing facility operation and care methods to accepted professional standards, while other aspects of the program, such as public education, could be evaluated by surveying feedback.

description: This paper studies the multiplicative semigroup generated by all rationals of the form (3n+2)/(2n+1) for nonnegative integers n, together with 1/2. The subsemigroup of integers in this semigroup is called the wild integer semigroup, and the wild numbers are the irreducible elements in this subsemigroup. This paper presents evidence that the wild numbers consist of all the prime numbers p except 3. The subsemigroup of integers in the multiplicative semigroup generated by all rationals of the form (3n+2)/(2n+1) for nonnegative integers n is called the Wooley integer semigroup and its irreducible elements are called Wooley numbers. This semigroup is shown to be recursive, and various open problems are formulated about Wooley integers.

description: We investigated the possibility of superconductivity in monolayer hexagonal boron nitride (h-BN) doped using each group-1 (Li, Na, K) and group-2 (Be, Mg, Ca, Sr, Ba) atom via ab-initio calculations. Consequently, we reveal that Sr- and Ba-doped monolayer h-BN and Ca-doped monolayer h-BN with 3.5% tensile strain are energetically stable and become superconductors with Tc values of 5.83 K, 1.53 K, and 12.8 K, respectively, which are considerably higher than those of Ca-, Sr-, and Ba-doped graphene. In addition, the momentum-resolved electron-phonon coupling (EPC) constant shows that the scattering among intrinsic π electrons around the Γ point dominates Tc. The scattering process is mediated by the low-energy vibration of the adsorbate. Moreover, compared with graphene, the stronger adsorbate-substrate interaction and lower symmetry in h-BN are critical for enhancing EPC in doped h-BN.

Non-Markovian qubit dynamics in a thermal field bath: Relaxation, decoherence and entanglement

description: We study the non-Markovian dynamics of a qubit made up of a two-level atom interacting with an electromagnetic field (EMF) initially at finite temperature. Unlike most earlier studies where the bath is assumed to be fixed, we study the coherent evolution of the combined qubit-EMF system, thus allowing for the back-action from the bath on the qubit and the qubit on the bath in a self-consistent manner. In this way we can see the development of quantum correlations and entanglement between the system and its environment, and how that affects the decoherence and relaxation of the system. We find non-exponential decay for both the diagonal and non-diagonal matrix elements of the qubit's reduced density matrix in the pointer basis. From the diagonal elements we see the qubit relaxes to thermal equilibrium with the bath. From the non-diagonal elements, we see the decoherence rate beginning at the usually predicted thermal rate, but changing to the zero temperature decoherence rate as the qubit and bath become entangled. These two rates are comparable, as was shown before in the zero temperature case [C. Anastopoulos and B. L. Hu, Phys. Rev. A {\bf 62} (2000) 033821]. On the entanglement of a qubit with the EMF under this type of resonant coupling we calculated, for the qubit reduced density matrix, the fidelity and the von Neumann entropy, which is a measure of the purity of the density matrix. The present more accurate non-Markovian calculations predict lower loss of fidelity and purity as compared with the Markovian results. Generally speaking, with the inclusion of quantum correlations between the qubit and its environment, the non-Markovian processes tend to slow down the drive of the system to equilibrium, prolonging the decoherence and better preserving the fidelity and purity of the system.

description: We demonstrate the application of pattern recognition algorithms via hidden Markov models (HMM) for qubit readout. This scheme provides a state-path trajectory approach capable of detecting qubit state transitions and makes for a robust classification scheme with higher starting state assignment fidelity than when compared to a multivariate Gaussian (MVG) or a support vector machine (SVM) scheme. Therefore, the method also eliminates the qubit-dependent readout time optimization requirement in current schemes. Using a HMM state discriminator we estimate fidelities reaching the ideal limit. Unsupervised learning gives access to transition matrix, priors, and IQ distributions, providing a toolbox for studying qubit state dynamics during strong projective readout.

description: We reduce the intensity noise of laser light by using an electro-optic modulator and a cousto-optic modulator in series. The electro-optic modulator reduces noise at high frequency(10 kHz to 1 MHz), while the acousto-optic modulator sets the average power of the light and reduces noise at low frequency (up to 10 kHz). The light is then used to trap single sodium atoms in an optical tweezer, where the lifetime of the atoms is limited by parametric heating due to laser noise at twice the trapping frequency. With our noise eater, the noise is reduced by up to 15 dB at these frequencies, and the lifetime is increased by an order of magnitude to around 6 seconds. Our technique is general and acts directly on the laser beam, expanding laser options for sensitive optical trapping applications.

Variables analyzed include aspects of farm structure, human capital, farm objectives, and production system employed by the producer. Results reveal that operation size and dependency upon income from the stocker operation, in particular, influence the adoption of recommended practices. Older producers and those pursuing a year-round production strategy were found to lag in adoption.

description: Sterile neutrinos are a minimal extension of the Standard Model of Particle Physics. A promising model-independent way to search for sterile neutrinos is via high-precision beta spectroscopy. The Karlsruhe Tritium Neutrino (KATRIN) experiment, equipped with a novel multi-pixel silicon drift detector focal plane array and read-out system, named the TRISTAN detector, has the potential to supersede the sensitivity of previous laboratory-based searches. In this work we present the characterization of the first silicon drift detector prototypes with electrons and we investigate the impact of uncertainties of the detector's response to electrons on the final sterile neutrino sensitivity.

Examining the health-seeking patterns of immigrant South Asian women : family members’ influence
Creators: name: Grewal, Sukhdev Kaur
Publisher: name: University of British Columbia
Year: 2009

description: Immigrant South Asian women living in Canada are not only at increased risk for health problems and experiencing unnecessary illnesses, they also face barriers to culturally appropriate and safe health care. There is a paucity of research exploring the health beliefs, practices and health-seeking behaviours of this vulnerable immigrant population residing in Canada. The purpose of this study was to examine the influence of family members on immigrant South Asian women's decision making related to their health concerns and their health-seeking behaviours. This study also sought to identify suitable strategies to facilitate their access to culturally appropriate and safe health care. This qualitative study was part of a larger study that examined the health-seeking practices of South Asian women living in the Lower Mainland of British Columbia. Using ethnographic methods, data was collected through face-to-face individual interviews with immigrant South Asian women. The sample included women of a variety of ages and religious backgrounds. Their years of residence in Canada ranged from 10 months to 31 years. Interviews were conducted in the language of the women's choice, and included Punjabi, Hindi, Gujarati, Urdu, Kutchi and English. Analysis of the translated and transcribed data revealed that the women did not make health decisions in isolation but in consultation with other family members. Overall, family members were perceived to be supportive in assisting women with their decisions regarding health issues. Family members provided both indirect and direct assistance and often responded positively to women's needs. The women were expected to fulfill their traditional roles and responsibilities as wives, mothers, caregivers, housekeepers, dutiful daughters, and daughters-in-law. These roles and responsibilities often affected the decisions they made with regards to their health. This way of living was shown in this study to be both positive and negative for the women in terms of their health. The findings from this study suggest implications for nursing practice, education, administration, and research. Health care providers should ensure that there are adequate resources available and that there is a provision of culturally sensitive, appropriate, and safe care for this special group of women. Health care providers should be equipped to provide care to South Asian women taking into account the women's relationships with their family and that the women are not alone in making health care decisions. Crosscultural courses should be integrated into nursing education. Future research needs to focus on replication of this study with a second-generation population. In addition, research is needed to examine the effect of arranged marriages on women's health.

description: The dielectronic recombination rate coefficients of N V and Ne VIII ions have been measured at a heavy-ion storage ring. The investigated energy ranges covered all dielectronic recombination resonances attached to 2s -> 2p (Delta n=0) core excitations. The rate coefficients in a plasma are derived and parameterized by using a convenient fit formula. The experimentally derived rate coefficients are compared with theoretical data by Colgan et al. (2004, A&A, 417, 1183) and Nahar & Pradhan (1997, ApJ, 111, 339) as well as with the recommended rate coefficients by Mazzotta et al. (1998, A&A, 133, 403). The data of Colgan et al. and Nahar & Pradhan reproduce the experiment very well over the temperature ranges where N V and Ne VIII are expected to exist in photoionized as well as in collisionally ionized plasmas. In contrast, the recommendation of Mazzotta et al. agrees with the experimental rate coefficient only in the temperature range of collisional ionization. At lower temperatures it deviates from the measured rate coefficient by orders of magnitude. In addition the influence of external electric fields with field strengths up to 1300 V/cm on the dielectronic recombination rate coefficient has been investigated.

description: Conversion of poultry litter to energy can serve as a renewable energy source and provide an alternative to land application in areas where poultry production is intensive. Economies of size may limit a farmer’s ability to economically use on-farm conversion. Capital costs can be spread across several poultry farmers to convert poultry litter to energy in a centralized facility. This research determined influences on the amount of litter poultry producers will to sell to a centralized conversion facility, on their willingness to invest in a conversion cooperative, and on the prices for litter required to divert litter from current uses.

description: Quantum devices are systems that can explore quantum phenomena, like entanglement or coherence, for example, to provide some enhancement performance concerning their classical counterparts. In particular, quantum batteries are devices that use entanglement as main element in its high performance in the charging powerful. In this paper, we explore the quantum battery performance and its relationship with the amount of entanglement that arises during the charging process. By using a general approach to a two and three-cell battery, our results suggest that entanglement is not the main resource to quantum batteries, where there is a non-trivial correlation-coherence trade-off as resource for the high efficiency of such quantum devices.

description: Rapidly declining gasoline prices from their record high during the summer of 2008, while ethanol prices remained relatively high, made it difficult for many bio-fuel policy modelers to fully explain the impacts of U.S. bio-fuel policies on fuel prices. Using profit-maximization models for blenders, refiners, and distillers, we conduct a comparative static analysis to measure the relative magnitudes of the impacts of tax credits and blending mandates on fuel-energy market equilibrium prices. Our results indicate that first, the prices of all fuels including conventional gasoline, ethanol, and blended gasoline decline as the biofuel tax credit increases, but they increase as the rate of the blending mandate increases. Second, the shadow value of a blending mandate represents the marginal rate of substitution between the marginal price change associated with a blending mandate and the marginal price change associated with a bio-fuel tax credit. Therefore, bio-fuel policies can affect the prices of all fuels including conventional gasoline, ethanol, and blended gasoline. Finally, ethanol imports are affected by domestic blender’s market-power effects, more than by the import duty imposed to offset the tax credit associated with the use of imported ethanol in the blending process.

description: Social collaborative platforms such as GitHub and Stack Overflow have been increasingly used to improve work productivity via collaborative efforts. To improve user experiences in these platforms, it is desirable to have a recommender system that can suggest not only items (e.g., a GitHub repository) to a user, but also activities to be performed on the suggested items (e.g., forking a repository). To this end, we propose a new approach dubbed Keen2Act, which decomposes the recommendation problem into two stages: the Keen and Act steps. The Keen step identifies, for a given user, a (sub)set of items in which he/she is likely to be interested. The Act step then recommends to the user which activities to perform on the identified set of items. This decomposition provides a practical approach to tackling complex activity recommendation tasks while producing higher recommendation quality. We evaluate our proposed approach using two real-world datasets and obtain promising results whereby Keen2Act outperforms several baseline models.

description: With the aim to investigate the statistical properties and the connection between thermal and non-thermal properties of the ICM in galaxy clusters, we have developed a statistical magneto-turbulent model which describes, at the same time, the evolution of the thermal and non-thermal emission from galaxy clusters. In particular, starting from the cosmological evolution of clusters, we follow cluster mergers, calculate the spectrum of the magnetosonic waves generated in the ICM during these mergers, the evolution of relativistic electrons and the resulting synchrotron and Inverse Compton spectra. We show that the broad band (radio and hard x-ray) non-thermal spectral properties of galaxy clusters can be well accounted for by our model for viable values of the parameters.

description: When a quantum system is subject to a thermal gradient it may sustain a steady non-equilibrium heat current, by entering into a so-called non equilibrium steady state (NESS). Here we show that NESS constitute a thermodynamic resource that can be exploited to fuel a quantum heat engine. This adds to the list of recently reported sources available at the nano-scale, such as coherence, entanglement and quantum measurements. We elucidate this concept by showing analytic and numerical studies of a two-qubits quantum battery that is alternatively charged by a thermal gradient and discharged by application of a properly chosen unitary gate. The presence of a NESS for the charging step guarantees steady operation with positive power output. Decreasing the duration of the charging step results in a time periodic steady state accompanied by increased efficiency and output power. The device is amenable to implementation with different nanotechnology platforms.

description: In response to nutria-linked degradation of much of its coastal wetlands, Louisiana established the Coastwide Nutria Control Program (CNCP) in January 2002. CNCP instituted, among other things, an ‘‘economic incentive payment’’ of $4.00 per delivered nutria tail from registered participants in the program. To examine whether this bounty has had an impact on nutria harvest and whether alternative bounty levels can, in general, generate additional harvesting activities, we developed a bioeconomic supply model that relates Louisiana’s annual nutria harvests to a suite of economic and environmental factors. Results suggested that the annual nutria harvest is responsive to both the price received per animal and costs. Results also suggested that the nutria harvest has increased as a result of the bounty, but that the initial bounty of $4.00 per tail may be insufficient to achieve the state’s goal of harvesting 400,000 animals per year but that a bounty equal to $5.00 per tail would likely achieve the stated goal.

description: We study electronic structures of quasi-two-dimensional finite electron systems in high magnetic fields. The solutions in the fractional quantum Hall regime are interpreted as quantum liquids of electrons and off-electron vortices. The ground states are classified according to the number of vortices inside the electron droplet. The theory predicts observable effects due to vortex formation in the chemical potentials and magnetization of electron droplets. We compare the transitions in the theory to those found in electron transport experiments on a quantum dot device and find significant correspondence.

description: We analyze temporal and spectral characteristics of Akhmediev breather and establish amplification and transmission of attenuated multi-soliton in nonlinear optical fiber. Our results show that the attenuated multi-soliton can be converted into Akhmediev breather through a judicious modulation of the spectrum. Subsequently, the maximally compressed pulse train of Akhmediev breather can be used to establish a robust breathing transmission by another spectrum modulation. In addition, the influence of the spectral modulation intensity on the excitation of Akhmediev breather and transmission of maximally compressed pulse train are also discussed.

description: While a substantial amount of research has been devoted to showing what social capital does, research explaining social capital itself lags behind. The literature has a long tradition of examining the effect of social capital on local economic growth and development. In this paper we examine whether local economic development can explain the variation in social capital across various geographical clusters in the state of Georgia. We begin by devising a measurement tool, a Human Development Index (HDI), to measure community development. Our social capital measure includes associational memberships, voluntary activities, and philanthropy obtained from the Georgia Social Capital Survey. The findings show that even after accounting for various demographic and economic characteristics, the HDI explains the variation in a number of social capital levels (especially those measured by associational involvement) across various geographical clusters in the state of Georgia.

description: Quantum key distribution (QKD) protocols are cryptographic techniques with security based only on the laws of quantum mechanics. Two prominent QKD schemes are the BB84 and B92 protocols that use four and two quantum states, respectively. In 2000, Phoenix et al. proposed a new family of three state protocols that offers advantages over the previous schemes. Until now, an error rate threshold for security of the symmetric trine spherical code QKD protocol has only been shown for the trivial intercept/resend eavesdropping strategy. In this paper, we prove the unconditional security of the trine spherical code QKD protocol, demonstrating its security up to a bit error rate of 9.81%. We also discuss on how this proof applies to a version of the trine spherical code QKD protocol where the error rate is evaluated from the number of inconclusive events.

S62 and S4711: Indications of a population of faint fast moving stars inside the S2 orbit -- S4711 on a 7.6 year orbit around Sgr~A*

description: We present high-pass filtered NACO and SINFONI images of the newly discovered stars S4711-S4715 between 2004 and 2016. Our deep H+K-band (SINFONI) and K-band (NACO) data show the S-cluster star S4711 on a highly eccentric trajectory around Sgr~A* with an orbital period of 7.6 years and a periapse distance of 144 AU to the super massive black hole (SMBH). S4711 is hereby the star with the shortest orbital period and the smallest mean distance to the SMBH during its orbit to date. The used high-pass filtered images are based on co-added data sets to improve the signal to noise. The spectroscopic SINFONI data let us determine detailed stellar properties of S4711 like the mass and the rotational velocity. The faint S-cluster star candidates, S4712-S4715, can be observed in a projected distance to Sgr~A* of at least temporarily $\leq$ 120 mas. From these stars, S4714 is the most prominent one with an orbital period of 12 years and an eccentricity of 0.985. The stars S4712-S4715 show similar properties with comparable magnitudes and stellar masses to S4711. The MCMC simulations determine confidently precise uncertainties for the orbital elements of S62 and S4711-S4715. The presence of S4711 in addition to S55, S62, and the also newly found star S4714 implies a population of faint stars that can be found at distances to Sgr~A* that are comparable to the size of our solar system. These short orbital time period stars in the dense cluster around the SMBH in the center of our Galaxy are perfect candidates to observe gravitational effects such as the periapse shift.

description: This report provides insight into four aspects of modeling indirect land use caused by expanded biofuels production. The report was motivated by the National Biodiesel Board’s interest in better understanding how the California Air Resources Board (CARB) estimated an indirect land-use factor for soybean-based biodiesel of 66 gCO2e/MJ, which is more than three times greater than the direct emissions from the fuel. Four aspects of CARB’s modeling approach were examined: (1) why CARB estimates that more U.S. forest than pasture will be converted to cropland; (2) whether CARB’s predicted land-use changes are consistent with observed U.S. land-use changes in the past decade; (3) how CARB could account for double cropping; and (4) whether CARB’s assumption that land brought into production has lower yields than land that was already in production. Results indicate that (1) much of the predicted U.S. forestland conversion is likely due to restrictions on cross-price elasticities imposed by use of the Constant Elasticity of Transformation supply function; (2) a stock of idled cropland could have accommodated the increase in U.S. cropland in 2007 and 2008; (3) the soybean yield elasticity with respect to price can be adjusted to account for double-cropped acres; and (4) there is no empirical support for the assumption that yields in Brazil on new land are lower than yields on old land. The analysis shows how much work needs to be done in this area if the models used to estimate indirect land use are to become widely accepted.

description: The structure of the observable algebra ${\mathfrak O}_Λ$ of lattice QCD in the Hamiltonian approach is investigated. As was shown earlier, ${\mathfrak O}_Λ$ is isomorphic to the tensor product of a gluonic $C^{*}$-subalgebra, built from gauge fields and a hadronic subalgebra constructed from gauge invariant combinations of quark fields. The gluonic component is isomorphic to a standard CCR algebra over the group manifold SU(3). The structure of the hadronic part, as presented in terms of a number of generators and relations, is studied in detail. It is shown that its irreducible representations are classified by triality. Using this, it is proved that the hadronic algebra is isomorphic to the commutant of the triality operator in the enveloping algebra of the Lie super algebra ${\rm sl(1/n)}$ (factorized by a certain ideal).
