description: Food reserves and trophallaxis help insect colonies regulate brood development and survive starvation events. Unlike wasps and bees, ants do not store food in external structures within the nest. Therefore, an ant colony’s ability to store food is greatly enhanced by the development of highly dimorphic workers and soldiers that are able to store food within their bodies. Carebara perpusilla (subfamily Myrmicinae, Emery, 1895) has a subterranean lifestyle and three castes: workers, soldiers with a proportionally larger head and gaster, and large winged queens. Workers are minute (1.5 mm long) and can hunt solitarily on tiny arthropods such as springtails and scavenge in groups on dead insects of various sizes. Rather than carrying big corpses to the nest, they bury it with soil and only retrieve haemolymph and small solid pieces. Moreover, some soldiers and virgin queens have a distended gaster and function as repletes. Food dyes revealed the storage of fat in the crop. Using dissections supplemented by micro-CT visualisation, we compared the crop of workers, soldiers and virgin queens and its capacity for considerable expansion. We discuss the morphological specialisation of repletes in ants that do not collect honeydew. Natural history data of more subterranean ants are needed to understand the adaptive context of foraging and other behaviours.

description: We use numerically exact quantum Monte Carlo (QMC) to compute the properties of three-dimensional bipolarons for interaction strengths where perturbation theory fails. For intermediate electron-phonon coupling and Hubbard U, we find that bipolarons can be both small and light, a prerequisite for bipolaron superconductivity. We use the QMC results to make estimates of transition temperatures, which peak at between 90-120 K and are demonstrated to be insensitive to Coulomb repulsion and impurities.

description: During the First World War, the warring parties included their colonial possessions in the hostility, either directly or indirectly. In West Africa, the proximity between the colonies of Germany and Britain ultimately made the region a theatre of war. Immediately the war started in Europe in 1914, hostility began between British Nigeria and German Cameroon lasting until 1916 when the Germans were defeated and ousted to the Spanish colony of Muni. This thesis seeks to explore the operational history of the war between British Nigeria and German Cameroon. Notably, the role of the Nigerian soldiers who formed the bulk of the British force facing a “peer-enemy” for the first time. This work will examine their movement from Nigeria to Cameroon, the successful amphibious landing at the Duala harbour, and their involvement in the eventual ousting of the Germans from Cameroon.

description: The SU(2) gauge theory with two massless Dirac flavors constitutes the building block of several models of Technicolor. Furthermore it has also been used as a template for the construction of a natural light asymmetric, or mixed type, dark matter candidate. We use explicit lattice simulations to confirm the pattern of chiral symmetry breaking by determining the Goldstone spectrum and therefore show that the dark matter candidate can, de facto, be constituted by a complex Goldstone boson. We also determine the phenomenologically relevant spin-one and spin-zero isovector spectrum and demonstrate that it is well separated from the Goldstone spectrum.

description: Breastfeeding from birth to 6 months has numerous benefits for maternal and child health. Mothers with chronic conditions are at risk for suboptimal breastfeeding outcomes, yet the underlying reasons for this are poorly understood. This thesis research investigated the factors associated with breastfeeding intentions, difficulties, and outcomes in mothers with chronic conditions. We conducted a prospective, community-based pregnancy cohort study called the Motherhood and Chronic Illness (MaCI) Study following 405 women from Alberta who reported living with a long-term physical health condition, carrying a singleton pregnancy, and intending to try breastfeeding. Women completed questionnaires at 32 weeks gestation, 6 weeks postpartum, and 6 months postpartum (overall response rate, 86.7%). In the prenatal period, we found that women who perceived their chronic condition to worsen during pregnancy were less likely to plan to exclusively breastfeed to 6 months per the global recommendation (adjusted odds ratio [OR] 0.50, 95% CI 0.30–0.82). From birth to 6 weeks postpartum, we identified three clusters of breastfeeding difficulties corresponding to physiologically expected lactation changes (51.1% of women), low milk production (15.4%), and ineffective latch (33.5%). Mothers with endocrine (adjusted relative risk ratio [RRR] 2.41, 95% CI 1.13–5.13), cardiovascular (adjusted RRR 2.87, 95% CI 1.02–8.09), and gastrointestinal (adjusted RRR 2.57, 95% CI 1.13–5.82) conditions were more likely to belong to the low milk production cluster and mothers with gastrointestinal (adjusted RRR 2.47, 95% CI 1.27–4.81) conditions were more likely to belong to the ineffective latch cluster, relative to the physiologically expected cluster. By 6 months postpartum, we found that one third (31.2%) of mothers had stopped breastfeeding, nearly all of whom did so earlier than planned. Compared to mothers who adhered to their pre-existing medications, mothers who did not adhere to pre-existing medications had shorter breastfeeding duration (adjusted hazard ratio [HR] 1.69, 95% CI 1.04–2.74) and greater odds of earlier than planned breastfeeding cessation (adjusted OR 1.85, 1.01–3.41). The MaCI Study highlighted three unique determinants of breastfeeding in mothers with chronic conditions, which can be addressed through person-centred support that jointly considers the ways in which breastfeeding patterns influence, and are influenced by, chronic condition status and management.
The relationship between management control systems and trust over the life cycle of an outsourcing contract
Creators: name: Sandher, Neha
Publisher: name: Monash University

Subjects: Uncategorized

description: The objective of this thesis is to answer the following research questions: Do management control systems (MCS) (specifically, formal and informal controls) and trust (specifically, competence and goodwill trust) change over the life cycle of an outsourcing relationship? If so, what factors drive this change? The study argues that outsourcing relationships typically operate in a volatile environment which makes it difficult to anticipate all the aspects of the relationship at the beginning. However, as the engagement between the parties develop, the level of learning and knowledge sharing improves which assists in defining the requirements more precisely. Therefore, the design and the use of MCS may be adjusted to accommodate for these changing circumstances. This study analyses the relationship between MCS and trust by considering the transaction characteristics as well as the life cycle stages of an outsourcing relationship. The research questions were investigated using evidence from a single case study of an IT outsourcing relationship. Overall the data demonstrated that MCS and levels of trust do change over the life cycle stages of an outsourcing relationship. The birth stage of the relationship was associated with a lack of clarity around tasks and activities. In this stage, the reliance was on establishing high levels of communications between the parties and managing the relationship through a trust-based pattern of control. As the relationship progressed, the level of information exchanged between the parties increased which assisted in establishing a bureaucratic-based pattern of control to manage the relationship. The reliance on formal controls lessened during the maturity stage of the relationship once the activities became repetitive and the process/procedures and performance targets were developed. The last two stages of the relationship were characterised by a more bureaucratic-based pattern of control.
Australian corporate responses to climate change: the Carbon Disclosure Project

Subjects: Uncategorized

description: Climate change issues have increasingly attracted government, business and professional attention in recent years. More specifically, there is mounting evidence that indicates that human induced carbon emissions are a major cause of climate change. The objective of the Carbon Disclosure Project (CDP) is to ensure that investors are better informed about the risks and opportunities facing the largest quoted companies worldwide due to climate change (CDP 2007). This thesis investigates the factors that influence a company's decision to participate in and disclose corporate carbon emissions information via the CDP. The relationship between the extent of "solicited disclosure", corporate governance and total carbon emissions are also investigated. Factors influencing the degree of "solicited disclosure" are furthered examined as an additional analysis of the study. Company size, equity offerings and regulation regimes are found to be the significant determinants of corporate responses to the CDP. However a company's decision to reply to the CDP questionnaire is found not to be influenced by leverage. Companies representing the Utilities, Energy, and Industrials sectors are more likely to respond to the "solicited" CDP information request compared to other sectors, namely Consumer, Materials, Finance and Health Care sectors. Managerial ownership and total carbon emissions are found to be negatively related to the level of carbon disclosure, while the relationship between proportion of non-executive directors and disclosure is significantly positive. The results are consistent with the prediction of agency theory. Size, Equity Offerings, Utilities Sector and the companies' last year's CDP response are found to be the significant variables in explaining the variability of the degree of "solicited disclosure".

description: Video abstract
description: The field of urban studies has scrutinised digital technologies and their proliferation, but rather little attention has been paid to databases. Furthermore, contributions to date have focused almost exclusively on how digital technologies interface with human populations in cities. By contrast, we draw attention to databases maintained by city governments that contain identifying information about pet dogs and their legal owners in cities. Methodologically, our study merges database ethnography with multi-species ethnography. Conceptually, we contend that “dog data” contribute to orderly conduct in urban space. This orientation to urban governance illustrates “trans-biopolitics,” in the sense of socially-situated and technologically-mediated power relations that operate through multi-species entanglements. As such, this article extends the literature on (neoliberal) urban policing by providing a fine-grained analysis of how emergent forms of social control become palpable. In general terms, the adoption and use of digital technologies by city governments has increased their capacity to enforce rules and regulations. Overall, we find that the more legible dogs and their legal owners become in databases, the more governable both dogs and people become in urban life.

description: Regulation of DNA replication and copy number are necessary to promote genome stability and maintain cell and tissue function. DNA replication is regulated temporally in a process known as replication timing (RT). Rif1 is key regulator of RT and has a critical function in copy number control in polyploid cells. Previously, we demonstrated that Rif1 functions with SUUR to inhibit replication fork progression and promote underreplication (UR) of specific genomic regions. How Rif1-dependent control of RT factors into its ability to promote UR is unknown. By applying a computational approach to measure RT in Drosophila polyploid cells, we show that SUUR and Rif1 have differential roles in controlling UR and RT. Our findings reveal that Rif1 acts to promote late replication, which is necessary for SUUR-dependent underreplication. Our work provides new insight into the process of UR and its links to RT. @font-face {font-family:"Cambria Math"; panose-1:2 4 5 3 5 4 6 3 2 4; mso-font-charset:0; mso-generic-font-family:roman; mso-font-pitch:variable; mso-font-signature:-536870145 1107305727 0 0 415 0;}p.MsoNormal, li.MsoNormal, div.MsoNormal {mso-style-unhide:no; mso-style-qformat:yes; mso-style-parent:""; margin:0in; mso-pagination:widow-orphan; font-size:12.0pt; font-family:"Times New Roman",serif; mso-fareast-font-family:"Times New Roman"; mso-bidi-language:BN;}.MsoChpDefault {mso-style-type:export-only; mso-default-props:yes; font-family:"Calibri",sans-serif; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:Calibri; mso-fareast-theme-font:minor-latin; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:Vrinda; mso-bidi-theme-font:minor-bidi;}div.WordSection1 {page:WordSection1;}

description: The search for heavy resonances in the dijet channel is part of the on-going physics programme, both at the Tevatron and at the LHC. Lower limits have been placed on the masses of dijet resonances predicted in a wide variety of models. However, across experiments, the search strategy assumes that the effect of the new particles is well-approximated by on-shell production and subsequent decay into a pair of jets. We examine the impact of off-shell effects on such searches, particularly for strongly interacting resonances.

Mind the gap : exposing the protection gaps in international law for environmentally displaced citizens of small island states
Creators: name: Walter, Kerstin
Publisher: name: University of British Columbia
Year: 2012

description: The President of the Maldives, Mr. Mohamed Nasheed, has stressed repeatedly that if current trends in sea level rise continue, the Maldives and other island countries would disappear before the end of the century. Despite the growing awareness of the nexus between climate change and migration, academic research into the legal protection, or even the legal definition, of people who may be induced or forced to leave their homeland due to the effects of climate change is scarce. Citizens of Small Island States, displaced as a result of climate change, have very specific characteristics that make them unique in international law but so far it is unclear what status and protection they will have under international law. This thesis aims to provide an overview over existing legal instruments, their capacity to protect island citizen and the ensuing duties and obligations on signatory states and the international community in the hope that it will provide a roadmap for future actions. The author first confirms the leading opinion that environmentally displaced people are not refugees before moving on to explore the protection capacity of international human rights law, the international legal principle of non-refoulement and the legal framework on statelessness. This thesis reaches the unwelcome conclusion that current legal frameworks are not equipped to provide displaced citizen of disappearing islands with the necessary and effective protection they require and none of the discussed legal instruments can confer on them a secure and stable legal status, comparable to that of a refugee. It further concludes that - seeing how specific the needs of these geographically remote islands are and taking into account the wishes of the populations at risk - the most promising way forward for the protection of small island states citizen therefore lies in regional agreements aimed at gradual and dignified migration and the preservation of island communities and culture within the host countries.

description: The experience of racialized students in university is an area that is not well understood in Canada, due to the lack of data on experience and concerns brought up by racialized students today. Postsecondary education is a time of transition and critical identity development, and identity can be a beneficial lens to understand racialized student experience in postsecondary education. The purpose of this research aims to bring attention to the experiences of racialized students in terms of the racism, lack of safety, profiling, and microaggressions they still face. The methodology used was qualitative, specifically ethnography. There were 132 survey respondents and 10 personal interviews conducted with STEM students in the undergraduate and graduate program who identified as racialized or a visible minority. In the analysis chapter, the survey and interview data are used to determine overarching themes that can then be used to improve the supports and experience of racialized students. Five themes were noted as common narratives during the data analysis: Representation/Recognition, Emotional Labour and Emotionality in Science, Safe Spaces, Geographical and Historical Identity, and Navigating University Norms. These themes are then used to offer some insights and interpretations that can be used to improve the experiences of racialized students.

description: Dentition is vital to our understanding of mammalian evolution. In this thesis, I use dental morphology as a basis for investigating various phenomena in mammalian dentition. First, I investigate the utility of shape, form, and linear measurement when differentiating species of the genus Mesodma – part of an early group of mammals known as the multituberculates. I found that shape and size metrics reveal different classifications of species. I conclude this chapter by suggesting these methods of differentiation should be investigated further along with the genus. Second, I investigate if cusp shape covariation across the premolar-molar boundary can highlight dental morphology covariance patterns that may contribute to the evolution of molarization in mammals. I found a significant difference in the cusp shape modularity among the two extant orders of hoofed mammals. I infer there are differences in the mechanism of molarization contributing to this differentiation. Further studies are required to infer a mechanism. The studies I present in these chapters showcase how dentition continues to provide important discoveries in the history of mammalian evolution.

description: Resistive gaseous detectors can be broadly defined as those operated in conditions where virtually no field lines exist that connect any two metallic electrodes sitting at different potential. This condition can be operationally recognized as 'no gas gap being delimited by two metallic electrodes'. Since early 70's, Resistive Plate Chambers (RPCs) are the most successful implementation of this idea, that leads to fully spark-protected gaseous detectors, with solid state-like reliability at working fields beyond 100kV/cm, yet enjoying the general characteristics of gaseous detectors in terms of flexibility, optimization and customization. We present a summary of the status of the field of resistive gaseous detectors as discussed in a dedicated closing session that took place during the XI Workshop for Resistive Plate Chambers and Related Detectors celebrated in Frascati, and especially we review the perspectives and ambitions towards the XII Workshop to be celebrated in Beijing in year 2014. Due to the existence of two specific reviews ([1,2]) also at this workshop, a minimum amount of overlap was found to be unavoidable. We have realized, however, that the three works provide a look at the field from different optics, so they can be largely considered to be complementary. Contrary to the initial concerns, the overall appearance seems to be fairly round, in our opinion.

description: We investigate the late time acceleration with a Chaplygin type of gas in spherically symmetric inhomogeneous model. At the early phase we get Einstien-deSitter type of solution generalised to inhomogeneous spacetime. But at late stage of the evolution our solutions admit the accelerating nature of the universe. For a large scale factor our model behaves like a ?CDM model. We calculate the deceleration parameter for this anisotropic model, which, unlike its homogeneous counterpart, shows that the flip is not syn- chronous occurring early at the outer shells. This is in line with other physical processes in any inhomogeneous models. Depending upon initial conditions our solution also gives bouncing universe. In the absence of inhomogeneity our solution reduces to wellknown solutions in homogeneous case. We have also calculated the effective deceleration parameter in terms of Hubble parameter. The whole situation is later discussed with the help of wellknown Raychaudhury equation and the results are compared with the previous case. This work is an extension of our recent communication where an attempt was made to see if the presence of extra dimensions and/or inhomogeneity can trigger an inflation in a matter dominated Lemaitre Tolman Bondi model.
HDR image construction from multi-exposed stereo LDR images
Creators: name: Sun, Ning
Publisher: name: University of British Columbia
Year: 2012

description: The vast majority of cameras in the market nowadays can only capture a limited dynamic range of a scene. To generate high dynamic range (HDR) images, most existing methods use multiple images obtained from a single low dynamic range (LDR) camera at consecutive instances. These methods can obtain good quality HDR images for still or slow motion scenes but not for scenes with fast motion. In this thesis, we propose the use of two LDR cameras which have different exposures. To generate an HDR image, the two differently exposed LDR images of the same scene are used. The two LDR images should be captured at the same instance, so as to deal with scenes with fast motion. The most challenging step in this approach is to obtain accurate estimates of the disparity maps of the scenes. This will allow us to correctly align the pixels from the two differently exposed pictures when forming the HDR images. Very few state-of-the-art stereo matching algorithms can deal with the problem of obtaining accurate estimates of the disparity map from two differently exposed images. This is because the input LDR images that are used to construct HDR images have large radiometric changes. In addition, the two input LDR images usually have saturations in different areas. To obtain accurate disparity maps, we present a novel algorithm that obtains an initial estimate of the disparity map. Then a refinement step is used to minimize the edge effect and interpolates the values in the saturated regions. Compared to other state-of-the-art methods, our algorithm has a simpler set up with only two standard commercial LDR cameras. The offline processing of the LDR images has a simpler cost function, especially the cost function we use in the refinement step of the disparity map. This reduces the computational complexity and thus the processing time of the LDR images to form the HDR image. Moreover, the disparity map computed by our algorithm can tolerate greater radiometric changes and saturations. Therefore, the HDR images constructed by our algorithm are smoother and have fewer defects than those constructed by other methods.
Analysing the misclassification of US mutual funds through soft clustering.

Publisher: name: Monash University
Year: 2017
Subjects: Uncategorized

description: This thesis investigates when, how and why the misclassification of US mutual funds occurs. Misclassification is defined as the dislocation between the advertised style of a fund and the actual investment style. Using soft clustering (Fuzzy C-means), over 27% of U.S. equity mutual funds are found to be misclassified from their reported S&P styles. This confirms claims from related literature that traditional styles which rely on self disclosure or third party classifications are prone to misclassification. Misclassified funds seem to experience deliberately gaming of style to the ulterior benefit of their fund managers. The bona fide investment style of a mutual fund, relative to all other funds, is more accurately provided by clustering funds over time in a technique called style-by-clustering. Due to high levels of misclassification, traditional styles provide a poor peer group upon which to form a peer benchmark when evaluating performance. Style-by-clustering provides more accurate peer groups due to the resistance of clustering to misclassification. Peer benchmarks formed from soft clusters are discovered to track returns more accurately than their S&P counterparts and so prove to be superior for performance evaluation. Thus, fund managers may be gaming traditional styles to report better performance. Using Fuzzy C-Means to partition funds into style gamers and non-gamers, the returns of style gamers are statistically different and higher than non-gamers over time. This 'smoking gun' is an economic motive for fund managers to deliberately misclassify themselves and is a key finding that explains why misclassification occurs. Style gamers seem to be deliberately misclassifying style to chase higher returns or to take advantage of an inappropriate peer benchmark to report a superior evaluation of performance.

description: Using a constructivist grounded theory method and taking a critical theory approach, this study aims to understand how people reporting eco-anxiety grapple with uncertainty about individual and collective futures in the context of the climate emergency. Data is drawn from public discussions about climate change in two online community forums hosted by the website Reddit. Findings are presented as dialectics representative of the multiple tensions and contradictions that frame and inform how people (primarily in the Global North) are currently making sense of the threat of climate change. These dialectics delineate several discursive dimensions of eco-anxiety and the meaning-making processes that people engage in to manage various forms of distress and how they (re)construct visions of viable futures. This project will contribute to sociological and psychological literature on the nature of eco-anxiety and the process of coping with uncertainty to enhance understandings of the impact of eco-anxiety on individual and collective well-being. In closing with a discussion of the implications for therapeutic practice, four pathways are suggested for stoking the burgeoning transformative process theorized here to be implicit in eco-anxiety.

description: We argue that dynamics of gapless Fractional Quantum Hall Edge states is essentially non-linear and that it features fractionally quantized solitons propagating along the edge. Observation of solitons would be a direct evidence of fractional charges. We show that the non-linear dynamics of the Laughlin's FQH state is governed by the quantum Benjamin-Ono equation. Non-linear dynamics of gapless edge states is determined by gapped modes in the bulk of FQH liquid. The dispersion of edge modes is traced to the double boundary layer of FQH states.

description: In the near-Earth space environment charged particles, mainly electrons and protons, are heavily influenced by Earth's magnetic field and can be captured for years and more. The number of particles with trapped trajectories accumulates over time to create regions of high-intensity radiation that are known as the Van Allen radiation belts. External forces can alter these trajectories such that particles are lost from the radiation belts and enter Earth's atmosphere where they deposit energy via collisions. The transfer of energy from particles that precipitate into the atmosphere triggers changes to the chemistry of the upper atmosphere that play a role in the destruction of ozone. This may engender long-term climate effects, but the extent of these changes has been difficult to quantify given that the flux and spectrum of precipitating particles is inherently difficult to estimate from limited point measurements of in-situ spacecraft. This thesis uses a globally integrated quantity, the Total Radiation Belt Electron Content (TRBEC), to quantify the rates of Energetic Electron Precipitation (EEP). The TRBEC is a single value that indicates the number of electrons in a given population in the radiation belts and its time rate of change is used to estimate the number of particles that are lost due to precipitation. The necessary framework of the TRBEC is first derived extensively followed by a demonstration of its ability to infer EEP by utilizing observations from the Van Allen Probes during a geomagnetically quiet interval in 2013. It is determined that the total number of electrons in the radiation belts has been overestimated in recent literature during the same period, at least by a factor of about 250. Simultaneously, a well-regarded EEP model underestimates precipitation rates compared to that from the TRBEC method, at least by an order of magnitude and generally much more.
Taxonomy-Driven Ontology Design

Ontologies

description: Taxonomies and ontologies are often merged. Ontologists might look upon taxonomies as the component or extension of ontologies to include hierarchies of subclasses. But it also goes the other way. Taxonomies can be semantically enriched to become ontologies with the addition of a high-level ontology model. This bottom-up approach to ontology creation leverages existing taxonomies. While stakeholder input and analysis of data are standard inputs into ontology design, taxonomies can serve as an additional source of input into designing an ontology. This session also addresses the difference of taxonomies and ontologies, presents benefits of taxonomy-based ontology design, and shows how an example taxonomy excerpt can serve as the basis for classes, object properties (semantic relations), and datatype properties (attributes).

description: The thesis hypothesises and largely finds more able managers positively affect firm investment efficiency consistent with prior findings that more able managers improve firm performance. The thesis extends this unconditional effect by moderating the relationship between managerial ability and firm investment efficiency on the level of managerial ownership and board monitoring in the firm, a condition that is missing in prior studies. The findings suggest increasing either managerial ownership or board monitoring in the firm significantly improves investment efficiency in companies managed by more able executives. In fact, where either managerial ownership or board monitoring reaches the lowest levels in the firm, more able managers no longer improve firm investment efficiency.
 The thesis uses regression analysis to test the hypotheses empirically. It relies on data collected from multiple databases to form a final sample of 58,734 firm-year observations of US listed firms between 1990 and 2014 for the unconditional effect of managerial ability on investment efficiency. Including the managerial ownership and board monitoring moderating variables reduces the sample to 19,317 and 11,314 firm-year observations, respectively. The thesis also performs a number of additional tests including studying individual components of aggregate investment and multiple robustness checks such as propensity score matching, firm-fixed effects and manager-fixed effects to enrich and corroborate the main findings.

The “Step-Ramp-Step” Protocol: Evaluating the Effects of a Smaller First Step Amplitude and Different Ramp Slopes to Determine the V̇O2 Mean Response Time and the Expression of the V̇O2 Slow Component During Ramp-Incremental Tests

description: The assumption that oxygen uptake (V̇O2) during ramp incremental (RI) testing can be used to prescribe constant-load exercise poses a few pertinent issues. First, this neglects the V̇O2 kinetics and time delay from the working muscles to the site of V̇O2 measurement, referred to as mean response time (MRT). Accurate estimation of the MRT following a RI test to exhaustion is critical for appropriately time-aligning the V̇O2-to-PO relationship. Furthermore, when using RI data, full expression of the delayed V̇O2 response (i.e., the V̇O2 slow component) makes identifying constant-load exercise above gas exchange threshold (GET) to the critical intensity of exercise (maximum metabolic steady state (MMSS), challenging. Therefore, the purpose of this study was to compare the estimated MRT when performing two step transitions of different intensities, and three different ramp rates. Prior to the RI test, using a step transition within the moderate-intensity domain (MOD), the constant-load V̇O2 at a given PO can optimize the estimation of the MRT. Additionally, through utilizing a heavy step transition (~50-65% peak PO) proceeding RI testing, identification of the V̇O2-PO relationship above GET can be made. This previously investigated approach known as the step-ramp-step (SRS) protocol was further applied and tested within this thesis across slow, moderate, and fast RI tests (15, 30 and 45 W·min-1 ramps) in a larger sample size (n=18). The results demonstrated that using a MOD as low as 50 W can result in accurate estimation of MRT for V̇O2. Additionally, identification of the V̇O2-PO relationship at the critical intensity of exercise was consistent irrespective of RI slope. Finally, the PO identified at GET using the 15 W·min-1 ramp was underestimated in comparison to the 30 and 45 W·min-1 ramps. These findings demonstrate the validity of using the SRS protocol with a smaller amplitude step (50W) different RI slope to accurately identify the V̇O2-PO relationship above the GET based on a moderate, and fast ramp, with some discretion required when using slower increasing ramps.
Abelian Extension of Standard Model with Four Generations

description: An abelian gauge extension of the Standard Model is proposed with a fourth generation. The fourth generation fermions obtain their masses from a heavier Higgs doublet which makes no tree level contributions to the first three generations masses. Light first three generations neutrino masses continue to have type I seesaw explanation whereas the fourth generation neutrino turns out to be a heavy Dirac neutrino. In the minimal version of such a model with no off-diagonal Yukawa couplings between the fourth and the first three generation, such a heavy Dirac neutrino can be long lived on cosmological time scales. In this model the stated LHC exclusion range $120 \; \text{GeV} < m_H < 600 \; \text{GeV}$ on the lighter Higgs placed in the context of generic fourth generation standard model is evaded. Also, the Dirac fourth generation neutrino in this model, if stable would constitute upto 1% of the cold Dark Matter in the Universe.

description: Exact solutions are constructed for a class of nonlinear hyperbolic reaction-diffusion equations in two-space dimensions. Reduction of variables and subsequent solutions follow from a special nonclassical symmetry that uncovers a conditionally integrable system, equivalent to the linear Helmholtz equation. The hyperbolicity is commonly associated with a speed limit due to a delay, between gradients and fluxes. With lethal boundary conditions on a circular domain wherein a species population exhibits logistic growth of Fisher-KPP type with equal time lag, the critical domain size for avoidance of extinction does not depend on. A diminishing exact solution within a circular domain is also constructed, when the reaction represents a weak Allee effect of Huxley type. For a combustion reaction of Arrhenius type, the only known exact solution that is finite but unbounded is extended to allow for a positive.

description: We study the following combinatorial game played by two players, Alice and Bob, which generalizes the Pizza game considered by Brown, Winkler and others. Given a connected graph G with nonnegative weights assigned to its vertices, the players alternately take one vertex of G in each turn. The first turn is Alice's. The vertices are to be taken according to one (or both) of the following two rules: (T) the subgraph of G induced by the taken vertices is connected during the whole game, (R) the subgraph of G induced by the remaining vertices is connected during the whole game. We show that if rules (T) and/or (R) are required then for every epsilon > 0 and for every positive integer k there is a k-connected graph G for which Bob has a strategy to obtain (1-epsilon) of the total weight of the vertices. This contrasts with the original Pizza game played on a cycle, where Alice is known to have a strategy to obtain 4/9 of the total weight. We show that the problem of deciding whether Alice has a winning strategy (i.e., a strategy to obtain more than half of the total weight) is PSPACE-complete if condition (R) or both conditions (T) and (R) are required. We also consider a game played on connected graphs (without weights) where the first player who violates condition (T) or (R) loses the game. We show that deciding who has the winning strategy is PSPACE-complete.
