description: Although there is growing interest in forgiveness in the workplace as a positive outcome for repairing workplace relationships, little is known about unforgiveness in response to workplace transgressions. This dissertation explores the conditions in which unforgiveness may be a functional response to a transgression. An exploratory qualitative study of supervisor narratives of subordinate transgressions systematically analyzed the nature of workplace unforgiveness, how it differs from forgiveness, and its functional value within the context of supervisor-subordinate relationships (Study 1). While forgiven narratives tended to minimize the offender’s role in the offense, unforgiven narratives tended to emphasize the negative consequences of the offense and portray the offense as diagnostic of moral flaws in the offender’s character. Additionally, in line with a risk protection view of unforgiveness, unforgiven narratives emphasized more rigorous behavioral safeguards to prevent the incident from reoccurring (e.g., changing policies, choosing not to assign future consequential tasks to the transgressor) compared to forgiven narratives. A quantitative critical incident study (Study 2) demonstrates that stronger supervisor unforgiveness post-transgression predicts greater use of task-based and relational exclusion as safeguards. This study further demonstrates that the positive links between supervisor unforgiveness and both types of exclusion safeguards are mediated by self-protection motives. Finally, an experimental study (Study 3) demonstrates that supervisors who express unforgiveness of a subordinate’s offense are viewed as more effective and less passive by third party observers compared to supervisors that forgive. The study also shows that supervisors who express unforgiveness engender reduced team member intentions to turnover from the team and improved team member satisfaction. Study 3 further demonstrates that these effects are mediated by the “doormat effect” – that is, compared to forgiving supervisors, unforgiving supervisors are less likely to be viewed as individuals who let others take advantage of them. Results are discussed in terms of the implications for future studies of workplace forgiveness and unforgiveness and the practical benefits of supervisor unforgiveness under certain circumstances.
Semi-Markov Driven Models: Limit Theorems and Financial Applications

description: This thesis deals with models driven by so-called semi-Markov processes, and studies some limit theorems and financial applications in this context. Given a system whose dynamics are governed by various regimes, a semi-Markov process is simply a process that ``keeps track" of the system regime at each time. It becomes fully Markovian if we ``add" to it the process keeping track of how long the system has been in its current regime. Chapter 1 consists of a global introduction to the thesis. We introduce the concepts of semi-Markov and Markov renewal processes, and give a brief overview of each chapter, together with the main results obtained. Chapter 2 introduces a semi-Markovian model of high frequency price dynamics: as suggested by empirical observations, it extends recent results to arbitrary distributions for limit order book events inter-arrival times, and both the nature of a new limit order book event and its corresponding inter-arrival time depend on the nature of the previous limit order book event. Chapter 3 establishes strong law of large numbers and central limit theorem results for time-inhomogeneous semi-Markov processes, for which the kernel is time-dependent. Chapter 4 develops a rigorous treatment of so-called inhomogeneous semi-Markov driven random evolutions, and extends already existing results related to the time-homogeneous case. Random evolutions allow to model a situation in which the dynamics of a system are governed by various regimes, and the system switches from one regime to another at random times. This phenomenon will be modeled by using semi-Markov processes. The notion of ``time-inhomogeneity" appears twice in our framework: random evolutions will be driven by inhomogeneous semi-Markov processes (using results from chapter 3), and constructed with propagators, which are time-inhomogeneous counterparts of semigroups. Chapter 5 presents a drift-adjusted version of the well-known Heston model - the delayed Heston model - which allows us to improve the implied volatility surface fitting. Pricing and hedging of variance and volatility swaps is also considered. Finally, chapter 6 concludes the thesis and presents some possible future research directions.

description: Oil palm is a perennial crop, which produces high oil yield compared to other vegetable oils. Oil palm fruit yields two types of oil, crude palm oil (CPO) and palm kernel oil (PKO). Palm oil contains an equal amount of unsaturated and saturated fatty acids; this property is unique among all vegetable oils and fats. This balance of saturated and unsaturated fats contributes to palm oil's stability, versatility, and its ability to give products a longer shelf life. Oil palm is valuable not just for its high oil output, but also for the byproducts it produces. Due to its low cost about 80% of palm oil find its way into food products. Palm oil can be used in cooking and in producing many food products like shortening, margarine, Transe-free vanaspati, cheese and yogurt, and bakery products etc.

description: Canada has abundant sources of fossil fuels such as coal and renewable sources such as switchgrass, sawdust and biosolids. Gasification is a process that utilizes fossil fuels and renewable fuels to produce synthesis gas. Adding species such as alkali and alkaline earth salts can catalyze the gasification process. However, the issues with catalytic gasification are the cost and recovery of catalyst. There is also the chance of synergy during the co-gasification of biomass with fossil fuels due to high concentration of catalytic species in biomass. In this thesis, the availability of the gasification catalysts, especially alkali and alkaline earth elements, naturally present on biomass feedstocks during the co-gasification with non-biomass feedstocks was identified. The influence of pyrolysis temperature on the physical and chemical properties of the feedstocks during transformation to char at 1 atm pressure and temperatures of 750 ºC to 950 ºC were investigated. The biomass feedstocks were switchgrass (16.8 wt% potassium in ash), sawdust and biosolids and the non-biomass feedstocks were sub-bituminous coal (30.5 wt% ash) and fluid coke (2.0 wt% ash). The kinetics of CO2 co-gasification of switchgrass (char and ash) with non-biomass feeds was determined using a thermogravimetric analyzer. High interparticle mobility of the potassium in switchgrass to non-biomass feed was observed. The potassium in the switchgrass/coal mixtures deactivated, likely due to formation of potassium aluminosilicate during the co-gasification. Presence of excess potassium in the mixture (K/Al molar ratio > 1) for catalytic activity was required to satisfy the stoichiometric requirements of the deactivation reactions. The extended random pore model satisfactorily described the gasification profile of single and binary mixtures. The activation energy was influenced by the concentration of the catalytically active form of potassium. An increase in potassium concentration through the addition of switchgrass ash instead of char resulted in a decrease in activation energy in switchgrass/ash-free coal mixture, while the trend was reversed for coal, which had more interfering inorganic matter. Analyzing the co-gasification kinetics of the switchgrass and biosolids indicated increasing calcium concentration may allow more potassium to remain in a catalytically active form.

description: The accuracy, transparency, and comparability of life cycle estimates are central to the controversy over the use of life cycle assessment to support policy. This thesis examines the potential for a Canadian formal voluntary standard to create product category rules for crude oil products. Such a standard would be developed at the Canadian Standards Association, and may enhance the credibility and improve the comparability of greenhouse gas emissions claims of Alberta’s oil sands products. A case study is developed as a narrative of key stakeholders in the proposed standard’s development, and interview findings are compared with hypotheses derived from standards literature. Challenges facing consensus in life cycle assessment were found to parallel those facing standards development organizations. Novel findings indicate widespread disagreement with the use of life cycle assessment to support regulation, substantial differences in the desired prescriptiveness of the standard, and a heavy focus placed on its revision post-implementation.

description: Past research suggests that a sense of humour plays a role in the workplace. The present study builds upon this work by exploring how individual differences in various positive and negative humour styles (affiliative, self-enhancing, self-defeating, aggressive humour) related to organizational citizenship behaviours, counterproductive workplace behaviours, and workplace anxiety and depression. Survey results from 190 employed undergraduate participants indicated that affiliative humour use is associated with reduced anxiety, depression and counterproductive workplace behaviours, and with increased engagement in organizational citizenship behaviours. In addition, self-enhancing humour moderated the relationship of organizational stressors with OCBs, anxiety and depression. In order to assess the interpersonal aspects of humour, convergence between self- and observer reported humour styles was examined. The relatively low correlation indicates we may need to move beyond the traditional measurement of self- and observer agreement to capture the unique variance of each perspective. Implications of these findings and future research directions are discussed.

description: Using the covariant spectator theory (CST), we present the results of a valence quark-diquark model calculation of the nucleon structure function f(x) measured in unpolarized deep inelastic scattering (DIS), and the structure functions g1(x) and g2(x) measured in DIS using polarized beams and targets. Parameters of the wave functions are adjusted to fit all the data. The fit fixes both the shape of the wave functions and the relative strength of each component. Two solutions are found that fit f(x) and g1(x), but only one of these gives a good description of g2(x). This fit requires the nucleon CST wave functions contain a large D-wave component (about 35%) and a small P-wave component (about 0.6%). The significance of these results is discussed.

description: Molecular Dynamics simulations (MD) were used to study how lipids interact with proteins, how proteins interact with each other in biological membranes, and the effects that the lipid environment has on these interactions. These studies were performed on the bacterial sensor protein DesK, which acts as a molecular switch to maintain membrane fluidity under different temperature conditions. Studies of pure lipid bilayers were performed to establish the effect of temperature on the pure bilayer as reflected by MD simulation. Interaction studies of proteins and lipids were performed on a minimal sensor protein, MS-DesK, identified experimentally as well as multiple representative Transmembrane Domain (TMD) peptides. The response of single instances of peptide (monomers) to change in temperature and bilayer thickness were studied with a focus on peptide location and orientation with respect to the bilayer, providing support for a thickness-based sensing mechanism. Further, the response of pairs of peptides (dimers) to change in membrane thickness and temperature was examined. Specifically, the role of helix-helix interactions in the mechanism of function of the protein was used to compare with different published models of function with a focus on the roles of sensing and signaling motifs. Following both experimental and theoretical observations the sequence of the linker peptide was examined for its role in signaling activity and protein function. This study shows that the protein is strongly located in the bilayer and that a thickness based sensing mechanism is viable. It also shows that previous suggestions of peptides sticking out of the bilayer are not supported by modeling results. The computations suggest that anchoring of both ends of the TMD to the boundaries of the bilayer and the change of the bilayer are most strongly correlated with protein activity.

description: The early stages of embryonic development rely on maternal products for proper regulation. However, screening for functional maternal-specific factors is challenging due to the time- and labor-intensive nature of traditional approaches. Here, we combine a computational pipeline and F0 null mutant technology to screen for functional maternal-specific chromatin regulators in zebrafish embryogenesis and identify Mcm3l, Mcm6l, and Npm2a as playing essential roles in DNA replication and cell division. Our results contribute to understanding the molecular mechanisms underlying early embryo development and highlight the importance of maternal-specific chromatin regulators in this critical stage.

description: The exploration of collisional fragmentation pheno-mena remains largely unexplored, yet it holds considerable importance in numerous engineering and physical processes. Given the nonlinear nature of the governing equation, only a limited number of analytical solutions for the number density function corresponding to empirical kernels are available in the literature. This article introduces a semi-analytical approach using the homotopy perturbation method to obtain series solutions for the nonlinear collisional fragmentation equation. The method presented here can be readily adapted to solve both linear and nonlinear integral equations, eliminating the need for domain discretization. To gain deeper insights intothe accuracy of the proposed method, a convergence analysis is conducted. This analysis employs the concept of contractive mapping within the Banach space, a well-established technique universally acknowledged for ensuring convergence. Various collisional kernels (product and polymerization kernels), breakage distribution functions (binary and multiple breakage) and various initial particle distributions are considered to obtain the new series solutions. The obtained results are successfully compared against finite volume method [26] solutions in terms of number density functions and their moments. The error between the exact and obtained series solutions is shown in plots and tables to confirm the applicability and accuracy of the proposed method.

description: Worldview-2 is the first very high resolution satellite imagery that has the ability to acquire data of eight bands named: Coastal (400 - 450 nm), Blue (450-510 nm), Green (510-580 nm), Yellow (585 - 625 nm), Red (630-690 nm), Red Edge (705 - 745 nm), Near Infrared(NIR) 1 (770-895 nm) and Near Infrared(NIR) 2 (860 - 1040 nm). Furthermore, five of these bands — Coastal Blue, yellow, red edge and NIR 2 are the new bands in WorldView-2 that are capable of extracting new features that were not possible with previous satellite imagery. Accurate and up-to-date bathymetric models are an effective tool for gaining a clearer understanding of the world’s waterways, and thus play an important role in many marine applications such as navigation. In this research, the automatic feature extraction technique will be used to locate water area edges. A threshold mask will then be used to determine small land and ships inside the shallow water area. An assessment will be done for all the eight bands to show their contribution to the bathymetry application and shore edge and shallow water outlining, with an emphasis on the yellow and Coastal bands. The conclusion and recommendation will be based on a statistical analysis of the comparison between Worldview-2 data and DEM data for the same area of interest.

description: We report the discovery of a new detached, double white dwarf system with an orbital period of 39.8 min. We targeted SDSS J163030.58+423305.8 (hereafter J1630) as part of our radial velocity program to search for companions around low-mass white dwarfs using the 6.5m MMT. We detect peak-to-peak radial velocity variations of 576 km/s. The mass function and optical photometry rule out main-sequence companions. In addition, no milli-second pulsar companions are detected in radio observations. Thus the invisible companion is most likely another white dwarf. Unlike the other 39 min binary SDSS J010657.39-100003.3, follow-up high speed photometric observations of J1630 obtained at the McDonald 2.1m telescope do not show significant ellipsoidal variations, indicating a higher primary mass and smaller radius. The absence of eclipses constrain the inclination angle to <82deg. J1630 contains a pair of white dwarfs, 0.3 Msun primary + >0.3 Msun invisible secondary, at a separation of >0.32 Rsun. The two white dwarfs will merge in less than 31 Myr. Depending on the core composition of the companion, the merger will form either a single core-He burning subdwarf star or a rapidly rotating massive white dwarf. The gravitational wave strain from J1630 is detectable by instruments like the Laser Interferometer Space Antenna (LISA) within the first year of operation.

description: Superconducting tips of YBa$_{2} $Cu$_{3}$O$_{7-x}$ were used to perform point-contact Andreev reflection spectroscopy on half-metallic CrO$_{2}$ thin films. At 4.2K, strong suppression of the d-wave Andreev reflection characteristics was observed, consistent with the high spin polarization of CrO$_{2}$. Our technique was validated by comparison with data taken on non-magnetic Au films, and with data taken by superconducting Pb tips. The point contacts were estimated to be $\lesssim$ 10nm in size, attesting to their ballistic and microscopic nature. Our results demonstrate the feasibility of using superconducting cuprate tips as spin-sensitive nanoprobes of ferromagnets.

description: Game engines provide sophisticated tools for rendering virtual environments. Their capabilities make them suitable for constructing detailed virtual environments. In this thesis, we present Eukaryo, an interactive, 3D model of a eukaryotic cell that was implemented in Unity and Unreal Engine. Eukaryo utilises mathematical modelling towards modelling enzyme kinetics, and agent-based modelling to illustrate the interaction between the individual proteins in the cell. Using hybrid modelling, Eukaryo is able to model the interactions for a diverse range of biological processes, such as protein activation pathways and cytoskeleton self-assembly. Further to this, Eukaryo provides support for virtual reality devices, such as the CAVE and Oculus Rift headset; users can immerse themselves in a virtual biomolecular environment. By combining state-of-the-art biological simulations with the 3D visualisations and real-time interactivity, Eukaryo provides an innovative environment for exploring cellular processes to convey the complexity in systems that constitute the machinery of life.
Effects of ocean acidification on different life history stages of northern abalone (Haliotis kamtschatkana)
Creators: name: Crim, Ryan Nathanial
Publisher: name: University of British Columbia
Year: 2010

description: Anthropogenic atmospheric CO₂ levels are rapidly increasing; however, much of this CO₂ (ca. 30%) dissolves into the surface ocean (upper 200 m) where it reacts with seawater and disrupts both ocean pH and carbonate chemistry, a process termed ocean acidification. Average pH of the surface ocean has already decreased by 0.1 units since the beginning of the Industrial Revolution and is expected to drop another 0.2 to 0.4 units by the end of this century. Of primary concern is the potential for ocean acidification to dramatically disrupt biological processes, especially biogenic calcification. Different life history stages may also be affected in different ways. Furthermore, interactions between ocean acidification and other environmental perturbations are often non-additive and thus result in non-predictive outcomes. Here, I investigate the effects of ocean acidification on different life history stages of an endangered abalone, Haliotis kamtschatkana. I reared larvae and adults under elevated CO₂ conditions (800 and 1800 ppm), representing levels expected by the end of this century and beyond. Adults were also reared under two temperatures (9 and 12°C) to investigate interactions between CO₂ and temperature. Larval survival, shell size and shell morphology were negatively affected by elevated CO₂. At 1800 ppm, almost all larvae completely lacked a shell. Adults seem more tolerant of elevated CO₂. Survival, growth and feeding rates were unaffected by elevated CO₂, at either temperature. Early life history stages may be more sensitive due to differences in calcification processes. Near future levels of ocean acidification may dramatically impair early development of H. kamtschatkana but later life history stages may be more tolerant. Since H. kamtschatkana population growth is thought to be currently limited by successful fertilization, decreases in larval survival may have severe consequences for the recovery of this endangered species. Efforts to mitigate the dramatic population decline of H. kamtschatkana will need to consider the potential repercussions of ocean acidification.

The Shepherdess in the Garden: Navigating the Routes of Female Mobility in the Urania

Subjects: subject: Education--Language and Literature

description: This thesis examines Urania’s navigation of the various garden spaces represented in Part One of Lady Mary Wroth’s pastoral romance The Countess of Montgomery’s Urania. This project seeks to show that the early modern pleasure garden in England may have been a cultural discourse that informed the portrayal of female subjectivity in the Urania. Since Urania is a pastoral figure in a text that predominantly adheres to the generic conventions of the chivalric romance, her experience of and movement through garden spaces engenders the interaction between the pastoral and romance genres in the Urania. It is in these moments of generic interplay in the enclosed space of the garden that narrative time expands in Urania’s memory, where her physical and mental mobility become visible expressions of female subjectivity.
Surfactant enhanced soil washing technique for removal of trace metals from contaminated soils
Creators: name: Xu, Beini
Publisher: name: University of British Columbia
Year: 2010

description: Increasingly stringent environmental regulations and legislation around the world are demanding the development of environmentally friendly technologies for contaminated site remediation. Researchers have recognized soil washing as an economically promising in-situ treatment method. Despite research indicating the effectiveness of soil washing with the aid of aqueous acids or chelating agents such as HCl and EDTA, the need to minimize the environmental impact of the remediation process itself has prompted investigations into alternative soil washing agents such as surfactants, particularly degradable compounds. This thesis examines two surfactants in their effectiveness of removing cadmium (Cd) and lead (Pb) from artificially contaminated kaolinite and illite clay minerals to determine the optimum conditions (concentration of surfactants and reaction time) for removing metals from contaminated urban sediments from two locations: a Wetland and a parking lot in Vancouver B.C. Selective sequential extraction was used to investigate geochemical fractionation before and after treatment of sediments by the surfactants. The optimum effective concentration for removing Cd and Pb from kaolinite and illite was 20 mM for Rhamnolipid for 0.5 h and Texapon at a concentration of 100 mM for 0.5 h. Thus, the concentration of 20 mM Rhamnolipid and 100 mM Texapon and reaction time of 0.5 h were selected to apply to remediate the two contaminated urban sediments. The removal of total metal content (Cu, Mn, Pb, and Zn) under laboratory conditions for the Wetland was 31%, 26%, 43%, and 27% after treatment by Rhamnolipid; and 31%, 27%, 58% and 31% after treatment with Texapon. The removal of these metals was 28%, 26%, 60%, and 31% by Rhamnolipid and 39%, 18%, 86%, and 40% by Texapon. Removal of metals from exchangeable and reducible fraction which have the potential to be released into environment approached up to 100%. Determination of Rhamnolipid and Texapon concentration remaining in Wetland and parking lot sediments after treatment revealed that more than 99% of remaining surfactants were removed from the two sediments after two washes with distilled water. The residual Rhamnolipid and Texapon were below the LD50/LC50 and toxicity limits for aquatic life.
Exploring Translanguaging Practice in Creating Digital Identity Texts in a Farsi Heritage Language Class

description: There has been little research done on young Farsi children who are learning their home language in Canada. The project of creating digital identity texts using Scribjab in a Farsi heritage language class was designed. The model was based on integrating translanguaging, a common language practice of bilingual and multilingual individuals who use multiple languages simultaneously for problem solving, meaning making, and communication. The study draws upon Cummins’ call for identity affirmation and Garcia’s theory of educational translanguaging. Nine students from the Farsi heritage language class participated in the study. Data for the study were collected from students’ identity texts, field notes, parents’ interviews, and students’ digital stories. The project was designed to enable students to use Farsi as well as English so that they could express real and imaginary identities. The majority of the students used English and Farsi to actively participate in whole group discussions, in their writings, and voice recordings. Results indicate that creating identity texts in two languages enabled students to utilize all the linguistic resources they bring to class. Rather than limiting students to reading, writing, and responding only in their second language, allowing students to use both languages provided them more opportunities to express their understanding of the content and become more engaged in learning their heritage language. The final digital books which have been published on Scribjab reveal that incorporating both Farsi and English offered them the chance to believe in their capabilities. Pedagogical implications about translanguaging practices in a heritage language school using Sribjab to teach young children are discussed.

description: An iterative method we previously proposed to compute nuclear strength functions is developed to allow it to accurately calculate properties of individual nuclear states. The approach is based on the quasi-particle-random-phase approximation (QRPA) and uses an iterative non-hermitian Arnoldi diagonalization method where the QRPA matrix does not have to be explicitly calculated and stored. The method gives substantial advantages over conventional QRPA calculations with regards to the computational cost. The method is used to calculate excitation energies and decay rates of the lowest lying 2+ and 3- states in Pb, Sn, Ni and Ca isotopes using three different Skyrme interactions and a separable gaussian pairing force.

description: Canadian dairy producers have been protected by supply management and import-restricting border controls for over forty years. As a result of the recent Trans-Pacific Partnership (TPP) negotiations, Canada has agreed to increase foreign access to its dairy market by an estimated 3.25 percent of its yearly milk production over the course of 5 years. As compensation, it is proposed that the Canadian government will pay domestic dairy producers approximately $4.3 billion over 15 years. This study estimates the welfare effects of the increased market access negotiated through the TPP, compares these effects to a free-trade scenario, and evaluates the proposed compensation package. It is estimated that the TPP generates approximately one third of the consumer surplus gains and producer surplus losses that would result from completely free-trade, and that the compensation package is justifiable.

description: Star formation is arguably the most important physical process in the cosmos. It is a fundamental driver of galaxy evolution and the ultimate source of most of the energy emitted by galaxies. A correct interpretation of star formation rate (SFR) measures is therefore essential to our understanding of galaxy formation and evolution. Unfortunately, however, no single SFR estimator is universally available or even applicable in all circumstances: the numerous galaxies found in deep surveys are often too faint (or too distant) to yield significant detections with most standard SFR measures, and until now there have been no global, multi-band observations of nearby galaxies that span all the conditions under which star-formation is taking place. To address this need in a systematic way, we have undertaken a multi-band survey of all types of star-forming galaxies in the local Universe. This project, the Star Formation Reference Survey (SFRS), is based on a statistically valid sample of 369 nearby galaxies that span all existing combinations of dust temperature, SFR, and specific SFR. Furthermore, because the SFRS is blind with respect to AGN fraction and environment it serves as a means to assess the influence of these factors on SFR. Our panchromatic global flux measurements (including GALEX FUV+NUV, SDSS ugriz, 2MASS JHKs, Spitzer 3-8μm, and others) furnish uniform SFR measures and the context in which their reliability can be assessed. This paper describes the SFRS survey strategy, defines the sample, and presents the multi-band photometry collected to date.

Self-phase modulation of a single-cycle terahertz pulse by nonlinear free-carrier response in a semiconductor

description: We demonstrate the self-phase modulation (SPM) of a single-cycle THz pulse in a semiconductor, using bulk n-GaAs as a model system. The SPM arises from the heating of free electrons in the electric field of the THz pulse, leading to an ultrafast reduction of the plasma frequency, and hence to a strong modification of the THz-range dielectric function of the material. THz SPM is observed directly in the time domain. In the frequency domain it corresponds to a strong frequency-dependent refractive index nonlinearity of n-GaAs, found to be both positive and negative within the broad THz pulse spectrum, with the zero-crossing point defined by the electron momentum relaxation rate. We also observed the nonlinear spectral broadening and compression of the THz pulse.

description: A multiagent system may be thought of as an artificial society of autonomous software agents and we can apply concepts borrowed from welfare economics and social choice theory to assess the social welfare of such an agent society. In this paper, we study an abstract negotiation framework where agents can agree on multilateral deals to exchange bundles of indivisible resources. We then analyse how these deals affect social welfare for different instances of the basic framework and different interpretations of the concept of social welfare itself. In particular, we show how certain classes of deals are both sufficient and necessary to guarantee that a socially optimal allocation of resources will be reached eventually.
Nonlinear plasma density modification by the ponderomotive force of ULF pulsations at the dayside magnetosphere

description: We investigate analytically and numerically a nonlinear modification of the magnetospheric plasma density under the action of the ponderomotive force induced by ULF traveling waves, using the nonlinear stationary force balance equation. This equation is applied to both the dipole and dayside magnetosphere having one and two minima of the geomagnetic field near the magnetospheric boundary. The separate and joint actions of the ponderomotive, centrifugal, and gravitational forces on the density distribution are shown.

description: This dissertation seeks to understand the relationship between ancient Maya identities and dress during the Late Classic period (A.D. 600-900), through an analysis of sartorial representations of members within the royal court. The specific research question that frames this dissertation is whether roles or offices within the ancient Maya royal court were made salient through dress. Rather than focus on one particular type of identity or office role, this dissertation takes a more holistic approach by considering all royal court members represented on painted ceramic vessels. In carefully examining painted imagery and providing a means of identifying inauthentic representations of dress, this research also helps to uncover the life histories of Maya ceramics. Using organizational dress theory, the study contributes a novel insight into the nature of Maya royal courts. It demonstrates that dress is a useful means of examining the political makeup and behaviour of courts, though at present it cannot alone speak to all the identities of those within the court. The study also reveals the difficulty of understanding active individuals from static representations, reflecting the fluidity with which courtiers were able to change dress and shift their identities. Overall, there is a lack of evidence that dress made specific courtly roles salient. Maya courtiers seem to have chosen dress elements that align with their gender identity and elite positioning—choices that were regulated by informal rules (or norms) in society.

description: Deposition of smaller granular particles on a larger nucleus particle has been simulated in two-dimension using molecular dynamics method. Variation of sequences of velocity of deposited particles is conducted and reported in this work. The sequences obey a normal distribution function of velocity with the same parameters. It has been observed that for velocity in range of 0 to 0.02 the densest deposited site (15-17 % number of grains) is located at about angle π/4 where location of injection point is π/4. And the less dense is about π/4 + π/2. Different sequences give similar result.

description: Millions of people are migrating from around the world. Many of these migrants are born in Asia. Migrants can transport infectious diseases and sexually transmitted ailments to the host country. Social Determinants that impact migrant’s health are educational conditions, culture-based superstition, language barrier, and life-style in the state of origin. There is also a difference between migrants and refugees. This poster clarifies that difference. This poster also suggested some strategies to fix the problems and discuss success in the migrant health agenda.
