Linzhang county and the culturally central periphery in mid-Ming China
Creators: name: Sedo, Timothy R.
Publisher: name: University of British Columbia
Year: 2010

description: This dissertation offers a local history of a small, peripheral county located in the most northern part of Henan Province during the Ming dynasty known as Linzhang County. Henan suffered a great deal from the wars that recurred frequently from the end of the Six Dynasties Period through the late fourteenth century and Linzhang County was among its many places that seemed to “fall behind” as the economic and cultural centres of the empire shifted to the south. Linzhang could however, claim a direct link with some of the empire’s most culturally central heartlands of the past. Given that the foundation of the Ming state followed a period of prolonged alien rule under the Mongol Yuan Dynasty, promotion of such “cultural centrality” was at the discursive core of the Ming state’s restorationist legitimacy. In this context, even a small peripheral county that went largely untouched by the dramatic commercial transformations characterizing southern China throughout the 15th to 17th centuries could rightfully claim a degree of “centrality” within the Ming realm. One particular mid-Ming magistrate named Jing Fang, realized this opportunity and in his tenure actively promoted projects that publicly linked the county to its distant antiquity. In just a few years Jing Fang successfully rectified Linzhang’s historic record; compiled and edited the county’s gazetteer; promoted the cult of the region’s most famous ancient culture hero, Ximen Bao; and renovated the county’s most important historic sites, temples and public buildings. Jing Fang’s dizzying pace of activity reveals the use and power of a stylized antiquity as a vital resource for local governance in north China during the mid-Ming period. While the dominant southern, or Jiangnan model of Ming studies emphasizes relatively autonomous commercial development and literati academic achievement as the key to late imperial wealth and culture, this “northern,” or perhaps more precisely “central” study gives more credit to state supervision and popular culture in the sustenance of this particular locality during the Ming period. It also offers a new local vantage point to begin to rethink the deeply regional characteristics of the composite Ming realm.

description: Separate populations of the same species often exhibit correlated fluctuations in abundance, a phenomenon known as spatial synchrony. Dispersal can generate spatial synchrony and more frequent dispersal increases synchrony. However, dispersal patterns investigated are typically simplistic and ignore occasional long-distance dispersal, which is common in natural systems. I used protist microcosms and theoretical models to investigate the impact of dispersal pattern on spatial synchrony. I found that occasional long-distance dispersal significantly increased spatial synchrony. This is due to the nonlinear relationship of synchrony to dispersal rate in the microcosm system. Increased long-distance dispersal at the expense of short-distance dispersal increased synchrony of widely separated populations without affecting short-distance synchrony. However, the theoretical models show that occasional long-distance dispersal can reduce short-distance synchrony without increasing long-distance synchrony, decreasing overall synchrony, depending on the shape of the dispersal rate-synchrony relation.

description: Newton's "superb theorem" for the gravitational inverse-square-law force states that a spherically symmetric mass distribution attracts a body outside as if the entire mass were concentrated at the center. This theorem is crucial for Newton's comparison of the Moon's orbit with terrestrial gravity (the fall of an apple), which is evidence for the inverse-square-law. Newton's geometric proof in the Principia "must have left its readers in helpless wonder" according to S. Chandrasekhar and J.E. Littlewood. In this paper we give an elementary geometric proof, which is much simpler than Newton's geometric proof and more elementary than proofs using calculus.

description: The 2016 Horse River wildfire in Northern Alberta devastated the community of Fort McMurray and surrounding areas, forcing residents to evacuate from their homes with little notice. Parents’ approach and style of communicating to their children about this event is critical in supporting family adaptability, resiliency, and children’s competence in making sense and meaning from their experience. Using Interpretative Phenomenological Analysis, the researchers sought to understand how parents make sense of their communication strategies to their children surrounding the 2016 Fort McMurray wildfire evacuation. Parents’ patterns of supporting their children were identified in the interviews of six Fort McMurray residents regarding their evacuation experiences. Results indicated three overarching themes of parents’ approaches to support: constructing realities, shaping values, and fostering independent construction. Understanding how parents effectively navigate natural disaster evacuations will assist professionals in meeting families’ needs in disasters and times of stress.

description: We study the role of periodically driven time-dependent Rashba spin-orbit coupling (RSOC) on a monolayer graphene sample. After recasting the originally $4\times 4$ system of dynamical equations as two time-reversal related two-level problems, the quasi-energy spectrum and the related dynamics are investigated via various techniques and approximations. In the static case the system is a gapped at the Dirac point. The rotating wave approximation (RWA) applied to the driven system unphysically preserves this feature, while the Magnus-Floquet approach as well as a numerically exact evaluation of the Floquet equation show that this gap is dynamically closed. In addition, a sizable oscillating pattern of the out-of-plane spin polarization is found in the driven case for states which completely unpolarized in the static limit. Evaluation of the autocorrelation function shows that the original uniform interference pattern corresponding to time-independent RSOC gets distorted. The resulting structure can be qualitatively explained as a consequence of the transitions induced by the ac driving among the static eigenstates, i.e., these transitions modulate the relative phases that add up to give the quantum revivals of the autocorrelation function. Contrary to the static case, in the driven scenario, quantum revivals (suppresions) are correlated to spin up (down) phases.

Examining the Impact of Direct Experience on Preservice Teachers' Self-Efficacy for Teaching in Inclusive Classrooms: a Quantitative Study
Creators: name: Peebles, Jodi Lynn
Publisher: name: Graduate Studies
Year: 2012
Subjects: subject: Education--Teacher Training
subject: Inclusive Education

description: With increased implementation of inclusive education in schools, teacher educators have been challenged to redesign their programs to prepare preservice teachers for educating exceptional students within the general classroom. This study examined the impact of an inclusive education course and a field experience on preservice teachers’ self-efficacy for teaching in inclusive classrooms. A within-subjects repeated measures design was used to collect data from 141 preservice teachers at three points in time: before the course, after the course, and after the field experience. The results indicated that both the inclusion course and the field experience produced significant increases in preservice teachers’ self-efficacy. Preservice teachers with prior experience with people with exceptional needs had higher levels of self-efficacy throughout the study; however, both groups of preservice teachers, those with prior experience and those without, demonstrated significant gains in self-efficacy. A multiple regression analysis indicated that, during the field experience, as preservice teachers spent more time with individual instruction with students with exceptional needs, and less time with observation and whole class instruction, their self-efficacy was more likely to increase. Also, the results of the study determined that self-efficacy had a small, but significant, correlation to self-esteem at each point in which the two constructs were measured. However, as the self-efficacy scores increased throughout the study, the self-esteem scores remained relatively unchanged, indicating that the two constructs are theoretically different. The results of the study were discussed in light of current research in the area, and implications for practice and research were suggested.

description: We report on recently performed simulations of Causal Dynamical Triangulations (CDT) in 2+1 dimensions aimed at studying its effective dynamics in the continuum limit. Two pieces of evidence from completely different measurements are presented suggesting that three-dimensional CDT is effectively described by an action with kinetic term given by a modified Wheeler-De Witt metric. These observations could strengthen an earlier observed connection between CDT and Horava-Lifshitz gravity. One piece of evidence comes from measurements of the modular parameter in CDT simulations with spatial topology of a torus, the other from measurements of local metric fluctuations close to a fixed spatial boundary.

description: An accelerating accumulation of recent data suggests that enhancers, the principal architects of transcriptional regulation, are as important as protein-coding sequences in the etiology of developmental diseases. Conditional knockout of murine Shox2 in limbs specifically disrupts chondrogenesis and the development of the humerus and femur, and is phenotypically similar to human SHOX-deficient patients, albeit different proximodistal locations are affected. Although we now have some understanding of the mechanism of Shox2 function in limb patterning, the molecular underpinnings of the cis-regulation of Shox2 to instruct stylopod development are unknown. We wished to identify enhancers that regulate Shox2 expression in limbs and subsequently delineate the limb-specific cis-regulatory topology of Shox2 utilizing a combination of different criteria for enhancer identification. In addition to enhancer-associated epigenetic signature profiling, we have utilized circular chromosome conformation capture (4C-seq) technology to probe the entire cis-regulatory organization of the Shox2 gene during limb development. We show five of numerous genomic regions within a 1.5 megabase (Mb) chromosomal territory surrounding the Shox2 gene that interact with this gene during limb development to drive similar Shox2-like limb lacZ activity in transgenic mice. The sequences we have identified will facilitate the search for transcription factors regulating Shox2 expression. Indeed, we found several previously determined GLI3 binding regions (Vokes et al., 2008) to overlap with a subset of characterized Shox2 limb enhancers and with the Shox2 gene, suggesting that hedgehog signalling may be a regulatory input for this gene’s expression. Genetic examination of composite Shox2/Gli3 and Shox2/Shh mutations show Shox2 to cooperate with Gli3 and Shh to pattern the stylopod.

description: Transition metal oxides hold great potential for the development of new device paradigms because of the field-tunable functionalities driven by their strong electronic correlations, combined with their earth abundance and environmental friendliness. Recently, the interfaces between transition-metal oxides have revealed striking phenomena such as insulator-metal transitions, magnetism, magnetoresistance, and superconductivity. Such oxide interfaces are usually produced by sophisticated layer-by-layer growth techniques, which can yield high quality, epitaxial interfaces with almost monolayer control of atomic positions. The resulting interfaces, however, are fixed in space by the arrangement of the atoms. Here we demonstrate a route to overcoming this geometric limitation. We show that the electrical conductance at the interfacial ferroelectric domain walls in hexagonal ErMnO3 is a continuous function of the domain wall orientation, with a range of an order of magnitude. We explain the observed behaviour using first-principles density functional and phenomenological theories, and relate it to the unexpected stability of head-to-head and tail-to-tail domain walls in ErMnO3 and related hexagonal manganites. Since the domain wall orientation in ferroelectrics is tunable using modest external electric fields, our finding opens a degree of freedom that is not accessible to spatially fixed interfaces.

description: Culturomics was recently introduced as the application of high-throughput data collection and analysis to the study of human culture. Here we make use of this data by investigating fluctuations in yearly usage frequencies of specific words that describe social and natural phenomena, as derived from books that were published over the course of the past two centuries. We show that the determination of the Hurst parameter by means of fractal analysis provides fundamental insights into the nature of long-range correlations contained in the culturomic trajectories, and by doing so, offers new interpretations as to what might be the main driving forces behind the examined phenomena. Quite remarkably, we find that social and natural phenomena are governed by fundamentally different processes. While natural phenomena have properties that are typical for processes with persistent long-range correlations, social phenomena are better described as nonstationary, on-off intermittent, or Levy walk processes.

description: The use of herbomineral formulation in the healthcare sector for different chronic diseases is gaining popularity due to its fewer side effects, high safety profile, and cost effectiveness. A new proprietary herbomineral formulation was formulated, consisting of four essential ingredients viz. herbal root extract (ashwagandha), and minerals (zinc, magnesium, and selenium). The study aims to evaluate the in vitro effect of Biofield Energy Healing (The Trivedi Effect®) on the test formulation using murine dendritic (DCs) and splenocyte cells. The herbomineral formulation was divided into two parts; one was represented as control, while the other part was treated with the Biofield Energy Healing Treatment remotely by eighteen renowned Biofield Energy Healers (The Trivedi Effect®) and defined as the Biofield Treated formulation. The effect of the test formulation on these cells were monitored by an estimation of pro-inflammatory cytokines level such as tumor necrosis factor (TNF-α), macrophage inflammatory protein (MIP-1α), and interleukin (IL-1β) in cell culture supernatants at the non-cytotoxic concentrations of the test formulation using MTT assay. The DCs were treated with the Biofield Energy Treated test formulation at different concentrations (i.e. 1.05 to 1052.5 µg/mL) for 24 hours, and the results showed significant (p≤0.001) suppression of TNF-α levels at all the tested concentrations with a maximum percentage decrease by 43.64% at 5.2 µg/mL concentration in the Biofield Treated formulation as compared with the untreated test formulation. Further, the Biofield Treated formulation also demonstrated inhibition of MIP-1α and IL-1β at a concentration range of 0.0000105 to 10.5 µg/mL in LPS stimulated splenocyte cells. There was a significant (p≤0.001) inhibition of MIP-1α (26.52%) and IL-1β (35.28%) in the Biofield Treated test formulation at concentration 0.000105 µg/mL and 0.0000105 µg/mL, respectively in comparison to the untreated test formulation. Overall, these results suggest that the Biofield Energy Healing based herbomineral formulation (The Trivedi Effect®) significantly down-regulated the tested cytokines expression in DCs and splenocyte cells as compared to the untreated formulation. Therefore, the Biofield Healing based formulation might be useful as a better anti-inflammatory product for many chronic and acute inflammatory disease conditions and autoimmune disorders. The Biofield Energy Treatment based formulation can also be effectively applied in cases of organ transplants, stress management and anti-aging by improving overall health.

description: The impact of earthquakes in urban areas is a complex problem compounded by multi-hazard and consequential risk issues, enormous inventory of vulnerable physical elements and the attendant socio-economic problems. An approach for assessment of urban earthquake risk is presented. Rational urban risk predictions and expected losses from major earthquakes in the future serve the basis and also provide strong reasons for the pro-active risk mitigation activities. The proposed approach is based on a combination of numerical values for the determined levels of consequences in the three considered areas (social consequences, material consequences, economic losses).

description: Using the framework of effective field theory, we present a detailed study of the Efimov effect in higher partial waves for systems of two identical particles and a third distinguishable particle. Depending on the total angular momentum $L$, the two identical particles must be bosons or fermions. We derive analytical expressions for the elastic and inelastic atom-dimer scattering cross sections as well as the atom-dimer relaxation rate at the dimer breakup threshold. For the experimentally most relevant case of P-waves, we numerically calculate the atom-dimer scattering cross sections and relaxation rates as a function of the scattering length, three-body parameter, and mass ratio for energies away from the breakup threshold.

Symmetry restoration and configuration mixing of axial and triaxial shapes are included in the calculations. Five 0+ states corresponding to different nuclear shapes are obtained below 2.25 MeV and several rotational and γ- bands built upon them are identified. Nevertheless, these states do not modify the β-decay half-life having a negligible effect in the rp-process. A good agreement with the available experimental data is obtained.

description: A recent development of smart materials called Iron-based Shape Memory Alloys (Fe-SMA) envisages a new perspective in the rehabilitation of structures. SMAs are metallic alloys that recover their original shape through heating. Utilizing this interesting feature of SMAs to retrofit reinforced concrete (RC) beams is the main objective of the current research project. An innovative active self-prestressing technique using Near Surface Mounted (NSM) Fe-SMA bars/strips for flexural strengthening of RC beams is proposed. The pre-strained (elongated) Fe-SMA bar/strip is anchored in a pre-cut groove in the tension side of the RC beam; heating the bar/strip will then trigger the recovery of the induced strain (i.e. the bar/strip tendency to shorten). However, due to the restrained ends of the bar/strip, a tensile force develops instead (i.e. prestressing force). In this case, no jacking tools or special anchorage systems are required. The main objective of this study is to examine the potential capability of the newly developed Fe-SMA as an active retrofitting material for RC beams. Consequently, its contribution to the flexural performance enhancement of the RC beam at service and ultimate load conditions was investigated. In addition, the long-term performance of the strengthened beams subjected to freeze-thaw cycles and fatigue loading was studied. In total, 11 RC beams were tested; 7 beams with a length of 2 meters and 4 large-scale beams with a length of 5 meters. The experimental test results revealed the effectiveness of the proposed technique in enhancing the flexural capacity of the RC beams at the service and ultimate load conditions, while maintaining a ductile failure mode similar to the under-reinforced beams. The strengthened beams tested under severe freeze-thaw cycles and fatigue loading showed a good performance except for the bonding between the Fe-SMA bars and the grout which experienced a rapid deterioration and resulted in a rupture of the Fe-SMA bar at the anchorage location under fatigue loading.

description: We consider a D-dimensional model of gravity with non-linear "scalar fields" as a matter source. The model is defined on the product manifold M, which contains n Einstein factor spaces. General cosmological type solutions to the field equations are obtained when n-1 factor spaces are Ricci-flat, e.g. when one space M_1 of dimension d_1 > 1 has nonzero scalar curvature. The solutions are defined up to solutions to geodesic equations corresponding to a sigma model target space. Several examples of sigma models are presented. A subclass of spherically-symmetric solutions is studied and a restricted version of "no-hair theorem" for black holes is proved. For the case d_1 =2 a subclass of latent soliton solutions is singled out.

Inpatient Pediatric Oncology Nursing Adolescent Relational Care: It is Different, the Difference, and Making a Difference

description: Adolescents diagnosed with cancer confront a unique set of psychosocial challenges related to their particular developmental stage. Adolescents have high rates of psychosocial distress at diagnosis and their distress rates remain high well into survivorship. A nurse’s knowledge and sensitivity to the unique intersection between adolescent development and having cancer is foundational to effective psychosocial care. Responsive relationships between adolescents and nurses may well ease the distress of being hospitalized for cancer treatment and mitigate the various unique psychosocial sequela that cancer has on the adolescent developing self. Very little research has been done to understand the experience and meaning of the relationships developed between inpatient pediatric oncology nurses and their adolescent cancer patients. My purpose in this philosophical hermeneutic inquiry was to better understand the experience of relationship between adolescents with cancer and pediatric oncology nurses on pediatric oncology inpatient units, from both nurse and patient perspectives. Eight participants who have or had cancer during adolescence (14-18 years of age) and four pediatric oncology nurses were interviewed with an intent to expand the meaning of this relationship as it applies to practice. These data were then analyzed according to hermeneutic tradition as guided by the philosophical hermeneutics of Hans-Georg Gadamer. Findings from this research revealed that adolescent needs are distinctive and important just because of their difference. Friendship-like adolescent-pediatric oncology nurse relationships on inpatient units are pivotal to a positive and developmentally constructive hospital experience. Developmentally appropriate relational nursing care includes: humor, social connection, “real speak,” being “rounded up” or treated older than chronological age, and friendship. The findings support the idea that friend-like relationships developed between nurses and adolescents are developmentally beneficial to the developing self and facilitate the integration of an adolescents pre-and-post cancer identity. Developmentally appropriate relational care of adolescents hospitalized for cancer on pediatric oncology units, I conclude, should be thought of as a psychosocial intervention in and of itself. Nurse-adolescent relationships are key to positive adolescent development in pediatric oncology inpatient care. The findings of this study underscore the need for future research that further understands the ways in which the inpatient pediatric oncology nurse-adolescent relationship may be therapeutic and the ways in which it is not.

description: We discuss and experimentally demonstrate a probabilistic Hadamard gate for coherent state qubits. The scheme is based on linear optical components, non-classical resources and the joint projective action of a photon counter and a homodyne detector. We experimentally characterize the gate for the coherent states of the computational basis by full tomographic reconstruction of the transformed output states. Based on the parameters of the experiment we simulate the fidelity for all coherent state qubits on the Bloch sphere.

description: Local volumetric groundwater (GW) contributions and non-point source (NPS) chloride loading to the Bow River were evaluated at the city scale in Calgary, Canada. In ten sampling and stream gauging events, discharge did not increase measurably between four locations three to five km apart. Mean chloride concentration and chloride mass flux (FCl-) increased with downstream distance due to NPSs. The major NPS of chloride was alluvial GW (379 mg/L, attributed to road salting). Mass-flux-based estimates of alluvial GW discharge were small (mean 0.02 m3 s-1 km-1) and spatially and seasonally similar. Local alluvial GW discharge to the Bow River was volumetrically insignificant (≤2% of river discharge), but at 7 g s-1 km-1, the chloride load was significant. The FCl- -based estimate of GW contribution to Bow River flow was consistent with long-term river discharge data that demonstrated that the majority of flow generation occurs upstream (92-95%) by mountain block recharge

description: Monitoring is one of the major concerns in offshore oil and gas production platform since the access to the offshore facilities is difficult. Also, it is quite challenging to extract oil and gas safely in such a harsh environment, and any abnormalities may lead to a catastrophic event. The process data, including all possible faulty scenarios, is required to build an appropriate monitoring system. Since the plant wide process data is not available in the literature, a dynamic model and simulation of an offshore oil and gas production platform is developed by using Aspen HYSYS. Modeling and simulations are handy tools for designing and predicting the accurate behavior of a production plant. The model was built based on the gas processing plant at the North Sea platform reported in Voldsund et al. (2013). Several common faults from different fault categories were simulated in the dynamic system, and their impacts on the overall hydrocarbon production were analyzed. The simulated data are then used to build a monitoring system for each of the faulty states. A new monitoring method has been proposed by combining Principal Component Analysis (PCA) and Dynamic PCA (DPCA) with Artificial Neural Network (ANN). The application of ANN to process systems is quite difficult as it involves a very large number of input neurons to model the system. Training of such large scale network is time-consuming and provides poor accuracy with a high error rate. In PCA-ANN and DPCA-ANN monitoring system, PCA and DPCA are used to reduce the dimension of the training data set and extract the main features of measured variables. Subsequently ANN uses this lower-dimensional score vectors to build a training model and classify the abnormalities. It is found that the proposed approach reduces the time to train ANN and successfully diagnose, detects and classifies the faults with a high accuracy rate.

description: My thesis argues that indigenous historical narratives demonstrate an understanding of the killer whale subjectivity that settler society is only beginning to comprehend. Set in the late 20th century, a period when human relationships with killer whales were undergoing a fast-paced reconfiguration, my research explores the spaces of orca-human encounter in regards to three killer whales: Moby Doll, the world’s first orca held in captivity; Skana, the first orca showcased at the Vancouver Aquarium; and Luna, the orphaned orca of Nootka Sound. Each example speaks to the common process by which humans project culturally-specific narratives and beliefs onto the lives of the whales. In the case of Moby Doll, I argue that the dominant discourse regarding the whale conformed to a strict gender script that functioned to silence other narratives and realities of Moby’s captivity. In my following chapter, I look at how the close relationship between Paul Spong and Skana inspired the scientist to abandon his most fundamental assumptions about orcas in favor of new affordances for orca subjectivity. Furthermore, I argue that the scientific research of John Lilly, a scientist who had a similar conversion experience with dolphins, inspired whole new literatures and imaginations of intelligent dolphins in New Age culture. Finally, I return to the recent story of the orphaned whale Luna to explore how these changing understandings of killer whales accompany an emergent recognition of the validity of indigenous ways of relating to both animals and the past. I argue that the conflict that arose between the Department of Fisheries and the Nuu-chah-nulth First Nation over the relocation of Luna is an instance of the informal negotiation of differing conceptions between settler and indigenous society over what is natural, what is right, what is history and what is the killer whale.

description: This study was designed to examine the acute metabolic response of men to the combined exposure to cold and hypoxia at rest. As the individual effects of both conditions have been extensively studied, our research focused on their combined effects in an effort to develop a better understanding of a lesser known topic. Eight participants (age:28.9±11.8 y; weight:80.7±11.5 kg; height:175.8±0.067 m; BMI:29±11 kg∙m⁻²) were recruited to participate in three experimental sessions for two hours on separate days. The experiment conditions included cold (C), hypoxia (H), and both cold and hypoxia combined (CH). Participants were asked to fast for 12 hours prior to beginning each experimental session. Once they arrived at the laboratory, the participants were instructed to lay in a supine position on a bed and were placed underneath a canopy for 30 minutes to measure their basal metabolic rate (BMR). Once the BMR protocol was complete, participants were then fitted with 4 wireless Electromyography (EMG) electrodes [trapezius (TR), pectoralis major (PE), rectus abdominis (RA), and rectus femoris (RF)] and were instructed to complete a maximal voluntary contraction (MVC) protocol for all four muscles. Shivering activity throughout the experimental sessions was expressed as percentage of the MVC values for each muscle group. Upon the completion of the MVC protocol, participants were asked to self-insert a rectal thermocouple, used to monitor core-body temperature throughout the sessions. Next, 11 skin thermo-sensors, using a modified Hardy and Dubois 12-point system, were applied directly to their skin, before they were finally fitted with a liquid conditioned suit. Once all initial procedures were complete, they were then transferred to an enclosed chamber to be exposed, in a random order while in a seated position, to C (FIO2=0.2093, 10°C), H (FᵢO₂=0.135 or ~2500m), or CH (10°C + FᵢO₂=0.135). Mean skin temperature significantly dropped over time during exposure in the climatic chamber from 31.9±0.9°C to 26.9±0.9°C and from 32.6±0.8°C to 26.4±1.0°C for C and C+H respectively, with no change in H, from 32.5±0.7°C to 33.1±0.7°C. Energy production (EP) responded accordingly, as it significantly increased over time from 5.8±0.6kcal·min⁻¹ to 10.6±1.9 kcal·min⁻¹ and from 6.0±0.9 kcal·min⁻¹ to 10.6±1.4 kcal·min⁻¹ for C and CH, respectively. A slight non-significant effect was observed in H, from 5.8±0.4 kcal·min⁻¹ to 6.7±0.7 kcal·min⁻¹. This effect was attributed to the seated position of the participants during exposure. The individual contributions of substrates to EP significantly differed between conditions over time, as glucose oxidation was higher during C when compared to H and CH, while lipid oxidation was higher during CH compared to C and H. To conclude, while the combination of CH did not impact energy production when compared to the other conditions, it did alter the contribution of individual substrates to energy production.

OPERA data and The Equivalence Postulate of Quantum Mechanics

description: An interpretation of the recent results reported by the OPERA collaboration is that neutrinos propagation in vacuum exceeds the speed of light. It has been further been suggested that this interpretation can be attributed to the variation of the particle speed arising from the Relativistic Quantum Hamilton Jacobi Equation. I show that this is in general not the case. I derive an expression for the quantum correction to the instantaneous relativistic velocity in the framework of the relativistic quantum Hamilton-Jacobi equation, which is derived from the equivalence postulate of quantum mechanics. While the quantum correction does indicate deviations from the classical energy--momentum relation, it does not necessarily lead to superluminal speeds. The quantum correction found herein has a non-trivial dependence on the energy and mass of the particle, as well as on distance travelled. I speculate on other possible observational consequences of the equivalence postulate approach.

description: What determines the design of an international court? Current literature on international courts is focused on what makes courts effective. However, we know less about how and why states seek to negotiate specific design features. This void sparks my driving question: what conditions and factors shape the design features of international courts? I attempt to answer this question through an analysis of the negotiations to create the International Criminal Court (ICC). Literature on the ICC points towards three factors that influenced the negotiations: the influence of a group of states, the influence of non-governmental actors, and the unique structure of the negotiations. Although these factors explain why some of the ICC’s design features give the Court significant independence in some areas, they do not explain why other design features restrict the Court’s independence. My thesis shows the importance of a fourth factor: the nature of the particular design feature.

description: We investigate static, planar, solutions of Einstein-scalar gravity admitting an anti-de Sitter (AdS) vacuum. When the squared mass of the scalar field is positive and the scalar potential can be derived from a superpotential, minimum energy theorems indicate the existence of a scalar soliton. On the other hand, for these models, no-hair theorems forbid the existence of hairy black brane solutions with AdS asymptotics. By considering a specific example (an exact integrable model which has the form of a Toda molecule) and by deriving explicit exact solution, we show that these models allow for hairy black brane solutions with non-AdS domain wall asymptotics, whose extremal limit is a scalar soliton. The soliton smoothly interpolates between a non-AdS domain wall solution at $r=\infty$ and an AdS solution near $r=0$.

description: Three phenolic compounds (±1 and 2) including a pair of new enantiomers were isolated from the sclerotia of Inonotus obliquus. Their structures were assigned by extensive spectroscopic analyses. All the compounds were evaluated for the neuroprotective activity against oxidative damage on human neuroblastoma SH-SY5Y cells induced by H2O2. Compound 2 showed remarkable neuroprotective effect and significantly improved the cell viability of SH-SY5Y cells treated by H2O2.
